Description
Technical field
The present invention relates to a kind of meet bolt self-locking device of mining electric locomotive.
Background technology
Under existing technical conditions, the material under the mine is mainly by electric locomotive transportation, and between electric locomotive and the compartment, what being connected between compartment and the compartment adopted is that meet bolt connects.The meet bolt of existing mining electric locomotive is divided into automatically and manually operated two big classes, but in the existing two big class meet bolt devices, at short notice under the situation of stopping walking, meet bolt is taken off pull out, promptly usually said unhook because of electric locomotive through regular meeting.Therefore it is necessary designing a kind of problem that fundamentally solves the unhook of meet bolt device.
Summary of the invention
Goal of the invention of the present invention provides a kind of simple for structure, fundamentally solves the meet bolt self-locking device of the mining electric locomotive of meet bolt device unhook problem.
For achieving the above object, a kind of meet bolt self-locking device of mining electric locomotive, it is included in head and the afterbody and both ends, the compartment rigid connector of electric locomotive, be provided with several contiguous blocks in the shrinkage pool of connector, the top of connector is fixing from lock tube, and Bolt with latching action is inserted in the endoporus of lock tube, contiguous block and connector; The end that described Bolt with latching action is included in pin rod is provided with back plate, is provided with several lateral pins on pin rod; Described top from lock tube is provided with several cotter ways, is provided with several rotary chutes from the jacket wall of lock tube.
For implementation structure optimization, improve, improve Combination property of the present invention, further step is:
The top of described back plate is provided with suspension ring.
Described cotter way is communicated with rotary chute.
The present invention adopts head and afterbody and both ends, the compartment rigid connector at electric locomotive, is provided with several contiguous blocks in the shrinkage pool of connector, and the top of connector is fixing from lock tube, and Bolt with latching action is inserted in the endoporus of lock tube, contiguous block and connector; Described Bolt with latching action comprises that an end of pin rod is provided with back plate, and pin rod is provided with several lateral pins; Described top from lock tube is provided with several cotter ways, is provided with several rotary chutes from the jacket wall of lock tube, and cotter way is communicated with the scheme of rotary chute, has solved the problem that existing meet bolt device easily breaks off relations.
The beneficial effect that the present invention is produced compared to existing technology:
1, the present invention have simple and reasonable, the advantage that cost is low.
2, solved each compartment of electric locomotive connecting portion meet bolt electric locomotive frequent stop walking variation the time, be prone to the unhook problem.
3, adopt Bolt with latching action in the positioning of rotating in the rotary chute of lock tube, under the effect of Bolt with latching action weight, reasonably avoided the notch that Bolt with latching action may be jumped out, guaranteed that Bolt with latching action can not jump out.
4, guaranteed that the transportation of electric locomotive is smooth, improved the safety of down-hole transportation.
The present invention be applicable between mining electric locomotive and the compartment be connected and the compartment between connection, the connecting device of power actuated vehicle.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Description of drawings
Fig. 1 is an assembly drowing of the present invention.
Fig. 2 is the front view of Bolt with latching action.
Fig. 3 is the front view from lock tube.
Fig. 4 is the birds-eye view of Fig. 3.
Among the figure: 1, contiguous block, 2, Bolt with latching action, 21, suspension ring, 22, back plate, 23, lateral pin, 24, pin rod, 3, from lock tube, 31, cotter way, 32, rotary chute, 4, connector, 5, attaching parts.
The specific embodiment
Extremely shown in Figure 4 by accompanying drawing Fig. 1, a kind of meet bolt self-locking device of mining electric locomotive, it is included in the head of electric locomotive and the both ends rigid connector 4 in afterbody and compartment, be provided with several contiguous blocks 1 in the shrinkage pool of connector 4, the top of connector 4 is fixing from lock tube 3, and Bolt with latching action 2 is inserted in the endoporus of lock tube 3, contiguous block 1 and connector 4; Bolt with latching action 2 comprises that an end of pin rod 24 is provided with back plate 22, and pin rod 24 is provided with several lateral pins 23; Be provided with several cotter ways 31 from the top of lock tube 3, be provided with several rotary chutes 32 from the jacket wall of lock tube 3.The top of back plate 22 is provided with suspension ring 21.Cotter way 31 is communicated with rotary chute 32.
The present invention in an embodiment, the rotary chute 32 on cotter way 31 quantity at lock tube 3 tops and jacket wall and lateral pin 23 quantity of Bolt with latching action 2 equate that preferable design quantity keeps balance more than 2 when utilizing Bolt with latching action 2 self-lockings.Rotary chute 32 is a through hole, with the endoporus perforation from lock tube 2.
When the afterbody of electric locomotive is connected with the compartment or two compartments when connecting, the attaching parts 5 of use is the chain of the band collar or the connecting panel of band through hole.
Use of the present invention is: attaching parts 5 is placed in the shrinkage pool of connector 4, between two contiguous blocks 1, the endoporus of attaching parts 5 is alignd with endoporus from lock tube 3, connector 4 and contiguous block 1, the pin rod 24 of Bolt with latching action 2 is inserted in the endoporus, the lateral pin 23 of Bolt with latching action 2 is sleeved in the cotter way 31 of lock tube 3, then along the direction rotary self-locking latch 2 of rotary chute 32, be stuck in the circular arc position of the extreme lower position of rotary chute 32 until lateral pin 23, and back plate 22 is pressed on the end face of lock tube 3, Bolt with latching action 2 is finished self-locking under the weight effect.The self-locking position of lateral pin 23 is in the extreme lower position of rotary chute 32, so Bolt with latching action 2 can not screw out from rotary chute 32.Solved that the prior motor car is connected with the compartment or two compartment bonded assembly meet bolt self-locking are poor, the problem that Bolt with latching action is easy to come off.
