Abstract
A kind of preventing escape bolt device, it is made up of pull bar, draw ring, shank and locking plate, and there is a through hole at columniform shank center, axially a groove is had bottom shank, pull bar is through in the through hole at shank center, and upper end connects a draw ring, and lower end radial direction installs a link bearing pin; Groove side bottom shank is provided with a limit shaft, and have elongated hole in the middle of the locking plate of strip shape, locking plate one end is rotatably connected on limit shaft, and the link bearing pin of pull bar lower end is arranged in the elongated hole on locking plate, and can slide in elongated hole.The utility model structure is simple, and manufacture handling ease, cost is low; The height of screw thread adjustable pull bar on pull bar, to adapt to different traction diameter of bores, locking plate rotates the upper-lower position of adjustable locking plate around limit shaft; Efficiently solve Mine haul vehicle in transit oblique, Vehicular vibration jolts the excessive jumping pin caused, and the vehicle caused disconnects and the phenomenon of sport car; Locking is convenient, reliable, improves the safety of transport.
Description
Technical field
The utility model relates to field of mine transportation equipment, particularly Mine haul vehicle preventing escape bolt device.
Background technology
Mine car connecting bolt is the vitals of Mine haul vehicle, be made up of bearing pin, round platform and draw ring, bearing pin inserts in the pin-and-hole of mine car connecting portion, round platform display snibbing position, prevent it from falling, round platform welds draw ring, facilitate staff to extract out and insert latch, latch and chain link arrange mine vehicle Connecting groups, meet level and inclination transportation request.
At present, mining company greatly Mine haul vehicle all uses cylinder plugs, and after this latch inserts car haul connecting bore, relying under normal circumstances self conducts oneself with dignity to there will not be to alter runs out of.But because latch lower end can not realize self-locking, in oblique lane transport, train vibration is jolted and can be occurred to jump pin phenomenon, causes mine car disconnect and cause sport car problem, there is larger potential safety hazard.
Summary of the invention
The purpose of this utility model is: design a kind of preventing escape bolt device, prevents Mine haul vehicle connecting bolt jumping pin problem in transit, reduces labour intensity and reduces potential safety hazard.
Realizing the technical scheme that the utility model object takes is: it is made up of pull bar, draw ring, shank, sliding sleeve, nut and locking plate, there is a through hole at columniform shank center, axially a groove is had bottom shank, pull bar is through in the through hole at shank center, upper end connects a draw ring, and lower end radial direction installs a link bearing pin; Groove side bottom shank is provided with a limit shaft, and have elongated hole in the middle of the locking plate of strip shape, locking plate one end is rotatably connected on limit shaft, and the link bearing pin of pull bar lower end is arranged in the elongated hole on locking plate, and can slide in elongated hole.
Screw thread has been attacked in pull bar upper end, and have a nut to spin in the above, draw ring is fixed on nut.
An annular stop boss is provided with on shank top.
Have a round boss in end, shank upper end, form a slideway between itself and annular stop boss below, have a lid formula sliding sleeve to be arranged on slideway, nut is fixed on sliding sleeve top, and pull bar is screwed on nut through sliding sleeve.
The length of sliding sleeve is substantially identical with the stroke of pull bar.
Good effect of the present utility model is: structure is simple, and manufacture handling ease, cost is low; Rely on the height of screw thread adjustable pull bar on pull bar, to adapt to different traction diameter of bores, rely on locking plate to rotate the upper-lower position of adjustable locking plate around limit shaft, reach link latch to mine vehicle locking and unblock; Efficiently solve Mine haul vehicle in transit oblique, Vehicular vibration jolts the excessive jumping pin caused, and vehicle disconnects and the phenomenon of sport car; Locking is convenient, reliable, improves the safety of transport, is also applicable to other tractor equipments simultaneously, has high economic value.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model; Accompanying drawing 2 is that A-A is to schematic diagram during blocking; Accompanying drawing 3 is that A-A inserts or released state schematic diagram to shank.
Detailed description of the invention
As shown in Figure 1, it is made up of pull bar 4, draw ring 1, shank 5, sliding sleeve 3, nut 2 and locking plate 8, there is a through hole at columniform shank 5 center, axially a groove 9 is had bottom shank 5, screw thread has been attacked in pull bar 4 upper end, be through in the through hole at shank 5 center, utilize the height of screw thread adjustable pull bar 4, make mine car locking plate adapt to different traction diameter of bores; A round boss 12 is had in end, shank 5 upper end, an annular stop boss 10 is provided with on shank 5 top, can prevent latch Action of Gravity Field from gliding, a slideway 11 is formed between two boss, have a lid formula sliding sleeve 3 to be arranged on slideway 11, nut 2 and draw ring 1 are welded on sliding sleeve 3 top, and pull bar 4 is screwed on nut 2 through sliding sleeve 3, sliding sleeve 3 can also play dustproof effect, and the length of sliding sleeve 3 is substantially identical with the stroke of pull bar 4.Pull bar 4 lower end radial direction installs a link bearing pin 6, groove 9 side bottom shank 5 is provided with a limit shaft 7, elongated hole 13 is had in the middle of the locking plate 8 of strip shape, locking plate 8 one end is rotatably connected on limit shaft 7, the link bearing pin 6 of pull bar 4 lower end is arranged in the elongated hole 13 on locking plate 8, and can slide in elongated hole 13.
When connecting mine car, upwards mention latch, draw ring 1 drives pull bar 4 upwards, the link bearing pin 6 of pull bar 4 bottom drives locking plate 8 to pack up, now locking plate 8 is recovered in the groove 9 of shank 5 bottom, at this moment latch can be inserted in car haul connecting bore, unclamp draw ring 1, pull bar 4 and sliding sleeve 3 are descending by deadweight, promote locking plate 8 to rotate around limit shaft 7, locking plate 8 one end is stretched out from shank 5 upper groove 9 side, the latch that actv. stops mining transportation vehicle to cause because of the factors such as vibration that are in operation moves up, thus play locking effect, effectively can solve the caducous hidden danger of mine car latch.
When needs decompose mine car, mention the draw ring 1 on latch, draw ring 1 drives pull bar 4 upwards, and the link bearing pin 6 of pull bar 4 bottom drives locking plate 8 to pack up, now locking plate 8 be recovered in latch groove, remove the locking of locking plate 8.When sliding sleeve 3 rising contacts with the round boss 12 on shank 5 upper end, drive shank 5 to move up together, thus whole latch is extracted from car haul position.
