A coiling reel mounting shaft is mounted in a bearing in the hollow coil spring shaft and a bearing in the instrument box, one end of the coiling reel mounting shaft is equipped with a coiling reel, and the other end is equipped with pinions; the pinions engage with a plurality of transition gears mounted on the instrument box, the transition gears engage with internal teeth, and the internal teeth are fixed in the middle part of an excircle surface of a coil spring box; the coil spring box is sleeved on the hollow coil spring shaft, and a flat spiral spring is installed in the coil spring box. A brake mechanism is also sleeved on an excircle of the tensile housing anchoring sheath. The number of the internal teeth is two to three times that of the pinions. A flange on the instrument box can be equipped with different supporting plates as needed. The gear coupling coil spring anti-galloping length and angle transducer stores potential energy by the coil spring mounted in the gear coil spring box, and the gear ratio of the internal teeth to the pinions that multiplies by the number of effective folding-unfolding turns of the coil spring doubles the number of rotation turns of the coiling reel, in the case that self-weight of the coil spring is lightened exponentially, coiling-up length of the coiling reel is remarkably increased; at the same time, frictional force increased due to excessive self weight of the coil spring is eliminated completely, and a stuck phenomenon and noise that occur frequently are eliminated; and weight and cost of the coil spring are greatly reduced, so that such fittings reach a higher level.
Description
Technical field
The utility model relate to a kind of detect the crane arm extension elongation and with the pick-up unit of ground angle degree, concrete is a kind of gear connection wind spring runaway length and angular transducer.
Background branch art
Present truck-mounted crane has been increasingly to maximize, and the elongation of its arm also increases greatly, and therefore, supporting length and angle detector are also constantly increasing and surveying long length and accuracy of detection with it.In order to increase the length of length and the recyclable line of pull of angular transducer, and keep certain pulling force, present Related product, be all to adopt two wind spring series connection, and even the mode of three wind spring series connection realizes.The result of doing like this, the one, cause terminal box more and more heavier; The 2nd, wind spring is also increasing because of the overweight frictional resistance that produces of conducting oneself with dignity; The 3rd, the effect that increases is more and more not obvious; The 4th, spring in the process that reclaims line of pull, stuck phenomenon occurs again and again; The 5th, spring when recovering to discharge potential energy suddenly, constantly sends ear-piercing dry sound.In addition, line of pull in use also frequent appearance break suddenly and cause driving, to such an extent as to damage other parts.
The utility model content
For the problem of above-mentioned existence, the utility model provides a kind of gear connection wind spring runaway length and angular transducer.This device has thoroughly solved terminal box mechanism on long-term puzzlement length and angle detector equipment to be difficult to continue to increase bracing wire and stuck phenomenon, the perverse ear noise of generation again and again occur, and because broken string produces driving, causes the problem of more havoc.
The technical solution of the utility model is: a kind of gear connection wind spring runaway length and angular transducer, comprise supporting plate, instrument box, drawing shell, hollow enwinding spring axis, winding roll, winding roll installation shaft, transition gear, internal tooth, coil spring box, it is characterized in that: supporting plate, instrument box, drawing shell, the anchoring cartridge that is fixed on drawing shell, hollow enwinding spring axis form fixed integral body; The winding roll installation shaft is arranged in hollow enwinding spring axis interior bearing and the bearing in instrument box, on an end of winding roll installation shaft, winding roll is installed, and the other end is equipped with pinion wheel; Pinion wheel is meshed with a plurality of transition gears on being arranged on instrument box, transition gear and internal tooth engagement, and internal tooth is fixed on coil spring box periphery middle part; Coil spring box is enclosed within on the hollow enwinding spring axis, and plane scroll spring is housed in coil spring box.
Also overlap braking mechanism is arranged on the cylindrical of the anchoring cartridge of described drawing shell, the arc surface of braking mechanism bottom and the inner arc surface of winding roll are in a certain angle, be placed with the column type elastic body between two arc surface angles, and on the drawing shell of this angle intersection point direction one side, the block that stops braking mechanism be housed.
The number of teeth of described internal tooth is 2-3 times of the pinion wheel number of teeth.
Flange on described instrument box can be installed different supporting plates as required.
Advantage of the present utility model: this device is by the wind spring savings potential energy that is contained in the gear coil spring box, and the product of the gear ratio of internal tooth and pinion wheel and the effective folding and unfolding number of turns of wind spring doubles the mode of winding roll rotating cycle,, in the situation that alleviate at double the wind spring deadweight, increased very significantly the take-up length of winding roll; Simultaneously, eliminate wind spring fully because of the overweight friction force that increases of conducting oneself with dignity, eliminated frequent stuck phenomenon and the dry sound that occurs; Also greatly reduce simultaneously weight and the cost of wind spring, make this type of accessory reach higher class.

Embodiment
Now by reference to the accompanying drawings, the utility model is further illustrated.
As shown in Fig. 1-6, supporting plate 1, instrument box 2, drawing shell 3, the anchoring cartridge 3.1 that is fixed on drawing shell 3, hollow enwinding spring axis 4 form fixed integral body; Winding roll installation shaft 6 is arranged in hollow enwinding spring axis 4 interior bearing 4.1 and the bearing 2.1 in instrument box 2, on an end of winding roll installation shaft 6, winding roll 5 is installed, and the other end is equipped with pinion wheel 6.1; Pinion wheel 6.1 is meshed with a plurality of transition gears 7 on being arranged on instrument box 2, and transition gear 7 and internal tooth 8 engagements, internal tooth 8 are fixed on coil spring box 9 periphery middle parts; Coil spring box 9 is enclosed within on hollow enwinding spring axis 4, and plane scroll spring 9.1 is housed in coil spring box 9.
Also overlap braking mechanism 10 is arranged on the cylindrical of the anchoring cartridge 3.1 of wherein said drawing shell 3, the arc surface 10.1 of braking mechanism 10 bottoms is in a certain angle with the inner arc surface 5.1 of winding roll 5, be placed with column type elastic body 10.2 between two arc surface angles, and on the drawing shell 3 of this angle intersection point direction one side, the block 3.2 that stops braking mechanism 10 be housed.2-3 times of pinion wheel 6.1 numbers of teeth that the number of teeth of described internal tooth 8 is.Flange 2.2 on described instrument box 2 can be installed different supporting plate 1 as required.
Principle of work: when plant equipment is pulled out line of pull, winding roll 5 drives winding roll installation shaft 6 and pinion wheel 6.1 synchronous rotaries thereupon, be distributed on pinion wheel 6.1 a plurality of transition gears 7 rotations on every side thereby refute, due to transition gear 7 and internal tooth 8 engagements, and internal tooth 8 is fixed on coil spring box 9, pulling force while making coil spring box 9 stretch out by line of pull, pass to plane scroll spring 9.1 savings with potential energy, regains line of pull while being used for the plant equipment counteragent.In the situation that the number of teeth of internal tooth 8 be pinion wheel 6.1 numbers of teeth 2-3 doubly, the number of turns of winding roll folding and unfolding line of pull also just on the basis of plane scroll spring number of active coils, enlarges 2-3 times.
