Description

Consecutive mining tractor

Technical field

The utility model relates to a kind of mining transportation locomotive, specifically is a kind of coal mine downhole crossheading consecutive mining tractor.

Background technology

In recent years, raising day by day along with down-hole comprehensive mechanical coal mining technology, the raw coal transportation has realized the large conveying quantity belt conveyerization, but the underground orbit assistant conveyance is more and more incompatible with it, especially adopt the exploiting field equipment of traditional puffer group relay-type transportation mode, the transportation of material, the transportation battle line is long, the link equipment of copying mechanically, personnel many, that take are many, poor safety performance, efficient are low.Therefore, the application of consecutive mining tractor in the underground orbit assistant conveyance is increasingly extensive, consecutive mining tractor is a kind of endless rope winch transport systems, comprise: endless rope winch, shuttle car, tail wheel, tightening device, be used to drag the steel rope of shuttle car, and be arranged at track holder rope rope press device along the line, be to provide power by endless rope winch, by the rope traction shuttle car, drag car team by shuttle car and come and go operation in orbit, realization is to exploiting field equipment, the efficient transportation of material, be mainly used in the big lane in mining face under mine crossheading and exploiting field and realize material, the equipment transportation, be specially adapted to the traction and the long distance transportation of large-scale fully-mechanized mining equipment, also can be used for the transportation of metal mine and ground rail, applicable to the rail transport of in easy flights and fluctuations.The shuttle car of existing consecutive mining tractor is employing voussoir fashion of extrusion when fixing steel rope, voussoir squash type steel rope fixed form is for fixing steel rope two ends, really a kind of good method of can yet be regarded as, but for consecutive mining tractor, the fixed sturcture relative complex needs the fixedly centre portion of steel rope usually, adopts fashion of extrusion easily to cause steel rope partial failure, installation simultaneously is difficult for, and is not easy to the down-hole practical operation; And when concrete the use, unclamp voussoir after, drag rope with manpower on one side, on one side with the moving storage of manpower dish rope sheave, labor strength is excessive.

Summary of the invention

The utility model for the shuttle car that solves existing consecutive mining tractor when the fixing steel rope, have the fixed sturcture relative complex, problems such as difficult be installed, provide a kind of steel rope fixed sturcture consecutive mining tractor simple, easy for installation.

The utility model is to adopt following technical scheme to realize: a kind of consecutive mining tractor, comprise endless rope winch, shuttle car, be used to drag shuttle car steel rope, be fixed in the conveying track end tail wheel, be arranged at track holder rope rope press device along the line, be arranged at the tightening device at endless rope winch rear, be fixed with the storage rope sheave on the vehicle frame of shuttle car, also be provided with solid rope sheave and bearing up pulley on the vehicle frame of shuttle car, bearing up pulley is provided with push bolt, and the lower end of push bolt is provided with the steel cable fixture block.During use, steel rope one end is fixed on the solid rope sheave, and holder rope rope press device, tail wheel that the other end is provided with on the way through endless rope winch, track store up on the rope sheave around being wound in behind the circle by bearing up pulley then, form the steel rope dragging system of a closure; Tighten the push bolt of bearing up pulley, steel cable fixture block by the push bolt lower end can compress the steel rope that is wound on the bearing up pulley, receiving restricts puts the push bolt that unclamps when restricting on the bearing up pulley, steel rope is involved in or rolls out the storage rope sheave to get final product, and solid rope sheave plays fixedly steel rope.Compared with prior art, the utility model is provided with solid rope sheave and bearing up pulley on the shuttle car vehicle frame, Gu the extension of steel rope and fastening is convenient in the setting of rope sheave structure, in the service life of having improved steel rope, strengthens safety performance; Setting up of bearing up pulley structure, changed unclamp voussoir in the past after, on one side drag rope with manpower, with the manpower tight rope situation of the moving storage of manpower dish rope sheave, reduced labor strength on one side; In a word, make the solid rope structure of shuttle car simple, easy for installation.

The utility model is provided with solid rope sheave and bearing up pulley on the vehicle frame of shuttle car, simple in structure, easy to use, and there is the structure relative complex in the shuttle car that has solved existing consecutive mining tractor when fixing steel rope, the problem that is difficult for is installed.

The specific embodiment

A kind of consecutive mining tractor, comprise endless rope winch 1, shuttle car 2, be used to drag shuttle car 2 steel rope, be fixed in the conveying track end tail wheel 3, be arranged at track holder rope rope press device along the line, be arranged at the tightening device 4 at endless rope winch 1 rear, be fixed with storage rope sheave 6 on the vehicle frame 8 of shuttle car 2, also be provided with solid rope sheave 5 and bearing up pulley 7 on the vehicle frame 8 of shuttle car 2, bearing up pulley 7 is provided with push bolt 10, and the lower end of push bolt 10 is provided with steel cable fixture block 11.During use, steel rope one end is fixed on the solid rope sheave 5, and holder rope rope press device, tail wheel 3 that the other end is provided with on the way through endless rope winch 1, track store up on the rope sheave 6 around being wound in behind the circle by bearing up pulley 7 then, form the steel rope dragging system of a closure; Tighten the push bolt 10 of bearing up pulley 7, steel cable fixture block 11 by push bolt 10 lower ends can compress the steel rope that is wound on the bearing up pulley 7, receiving restricts puts the push bolt 10 that unclamps when restricting on the bearing up pulley 7, steel rope is involved in or rolls out storage rope sheave 6 to get final product, and solid rope sheave 5 plays fixedly steel rope.

During concrete enforcement, the endless rope winch of the JWB-55 type that described endless rope winch 1 employing University Of Science and Technology Of Shandong electromechanical research is produced, this type endless rope winch speed change adopts friction wheel planetary clutch mode, manually nearly machine operation, variable speed operation is convenient, flexible.Specifically, this type endless rope winch has adopted third-level planetary train deceleration transmission, the planetary differential of motor input shaft through-coupling constant-mesh, fast, at a slow speed manually under the corresponding combination of block brake lock, form zero-speed, fast and at a slow speed, last transmission last level planet circular system and bipyramid friction roll.Can realize: 1, electrical motor starting under no load, cargo are realized zero-speed or buffer starting at a slow speed, do not have the starting danger that slides down; 2, winch two grades of speed changes in service satisfy different material, the speed of different tunnels condition, moment requirement; 3, the speed before and after a lot of volt roadway slope changes is switched arbitrarily.And adopt friction wheel on the structure, realize forward and reverse all have reliable constant tensile force and propulsive effort, no skidding.

In addition, during for the operation of assurance continuous drafter, steel rope has stable initial tension, must dispose tightening device, and described tightening device 4 adopts Hydranlic tensioners, and its specific implementation is that those skilled in the art are easy to realize; Tightening device described in the utility model adopts rear portion tensioning mode, utilize the rear portion tensioning can absorb the part that steel rope system extends owing to elastic deformation, and provide enough tensile forces for winch, guarantee that steel rope has more stable positive pressure on the bipyramid friction roll, impel winch normally to draw, prevent that steel rope from skidding on the bipyramid friction roll of endless rope winch.
