Description
Technical field
Hydraulic support disintegration ejector pin device, belongs to colliery support solution pin apparatus field.
Background technology
Install in colliery, withdraw in work.Because some hydraulic support volumes in mine are large, heavy, be subject to the restriction of transportation route on the way, the support packing that needs after withdrawing from first to disintegrate could be gone up well.The traditional dismantle processes of hydraulic support is first to use mantle fiber bolt to be packaged silk the bolt hole on round pin, uses 24 or 30 the bolt tightening of pulling pin, and re-uses pin pulling out device and is hauled out.But because hydraulic support uses for a long time in down-hole, can cause the connecting pin of each parts in disintegration process to be difficult to extract.The bolt that often occurs pulling pin pulls off or extracts even situations such as connection chain pull off, operating personnel separating in pin process that labour intensity is higher, safety can not get ensureing hindering simultaneously and withdraws speed and affect normal organism of production.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of simple in structure, safety good, efficiency is high, labour intensity is low hydraulic support disintegration ejector pin device is provided.
The technical solution adopted for the present invention to solve the technical problems is: this hydraulic top pin assembly, it is characterized in that: comprise the bracing frame being slidably installed in base, base and be welded on the oil cylinder at bracing frame top, described base bottom and bracing frame middle part are provided with crossbeam, between two crossbeams, are flexibly connected by Lift Part; On described oil cylinder front and back sides, corresponding stand connection is housed, oil cylinder connects feeding means by sebific duct.
Effect of the present invention is to provide a kind of ejector pin device for large, the heavy support of mine inner volume, base of the present invention and bracing frame can be supported on desired position by ejector pin assembly, when oil cylinder starts ejector pin work, the feeding means that sebific duct connects can have certain distance from support.Stand connection is connected this ejector pin device behind location with the round pin of support, staff can control at feeding means place ejector pin, even can in the blindage arranging, hide oneself, and ensures constructor's safety.The course of work only need be fixed ejector pin setting position and be controlled feeding means, and labour intensity reduces greatly, and operating efficiency obtains larger raising.
Described Lift Part is jackscrew or hydraulic jack.
The a pair of middle part that angular vertex is hinged on respectively to crossbeam of described jackscrew, another of jackscrew is to being connected with rocking bar to screw thread between angular vertex; Described rocking bar is made up of the crank of threaded rod and threaded rod one end welding, and threaded rod comprises and is provided with two parts before and after reverse thread.
Lift Part is selected jackscrew of the present invention, and simple in structure being easy to controlled, and lifting process is stable.Jackscrew of the present invention utilizes rocking bar can arbitrarily regulate height, thinks and closely controls without extra power, and operating process is convenient, simple, steady.
Described stand connection comprises two parts before and after adjusting rod and hook, and adjusting rod one end is hinged on oil cylinder, and the adjusting rod other end and hook socket are offered multiple equidistant screws and fixed by bolt on adjusting rod and hook.The present invention adopts this simple stand connection that this ejector pin device is connected to location with the support that needs dismounting round pin.When aggressiveness operation, only hook need be hung on support, regulate adjusting rod and the fixing position of the upper bolt of hook, make hook as far as possible stressed, control afterwards oil cylinder and extend, round pin can be ejected.The adjusting rod of both sides and hook screwhole position are certain, and length is constant, ensure the center of oil cylinder and the center of round pin all the time point-blank, prevent from being offset and cause danger.
Described feeding means can be selected hand supercharging bar.Feeding means selects hand supercharging bar to meet drive environment, without additional energy source power is provided, is easy to carry about with one and moves, operates easily.
Described oil cylinder enters, liquid return hole is equipped with hydraulic two-way lock.
Described base and bracing frame be the cube framework for being surrounded by four armstands and horizontal beam all, and four armstand inner sides of base form slideway, and bracing frame is slidably mounted in slideway bracing frame can be slided up and down in base.The material of its neutral arm is angle steel, and the material of crossbeam is band steel.Bracing frame and base ensure that lifting is steady, and the quadrangle bottom surface that base forms is easy to obtain diagonal, determines center of gravity, and the mechanism while ensureing work is steady.Slideway when base forms bracing frame lifting, the support force that lifting provides side direction steadily can also to the bracing frame on top and oil cylinder, ensures in oil cylinder ejector pin process all the time the center of oil cylinder and the center of round pin point-blank, and is not offset.
It is ejector pin accessory that this hydraulic top pin assembly is furnished with ejector pin piece, and ejector pin piece is cylindrical bloom.In ejector pin process, round pin occurs after a loosening backward outer cheap segment distance, and pin-and-hole leaks outside, and ejector pin piece is placed in pin-and-hole, again fixes this ejector pin device, and ejector pin piece is aimed at the center of oil cylinder, utilizes ejector pin piece round pin to be ejected completely again.Ejector pin piece is acted for sb behind the position of round pin, and support is avalanche at once not, and ejector pin piece easily takes out.For convenience detach.In process, can not incur loss through delay other work of pulling pin of ejector pin device.
Compared with prior art, the beneficial effect that hydraulic top pin assembly of the present invention has is: the application of hydraulic top pin assembly, guarantee the personal safety of ejector pin process, the chain rupture of having stopped to pull pin, damaged the phenomenon of pulling out screw, improved pull pin effect and efficiency simultaneously.Coming into operation of hydraulic top pin assembly improved the personal security coefficient in support disintegration process.Reduce construction link, greatly reduced workman's labour intensity.Improve efficiency, stopped the phenomenon of doing over again.Simple in structure, with low cost, there is social benefit and promotional value widely.
