Abstract
The utility model relates to a safety device for the track haulage of a mine, which is used for self-locking and preventing unhooking for a mine-car link pin. The utility model is composed of a guide plate on the wall of a car box, a square-frame-shaped supporting frame, a flexible connecting element, a self-locking block, and a pin shaft frame and a pin shaft which are arranged on a car frame. The frame edge of the upper part of the supporting frame is sheathed in the frame of the guide plate, and is connected with one end of the flexible connecting element; the lower part of the supporting frame is hinged with the self-locking block. The self-locking block which is hinged with the pin shaft frame is provided with a clamping opening which clamps the bayonet on the upper part of the mine-car link pin. The device has the advantages of simple structure, easy manufacture and installation, convenient operation and reliable work, effectively prevents the link pin from unhooking, and conveniently achieves that a mine car can not be turned over without unhooking when a cage turns over.
Description
The utility model relates to the safety guard of mine rail transportation, further is a kind of mine car attachment pegs lock hook self-locking device that is used for preventing mine car transportation unhook.
At present, in colliery, metallurgical mine rail transport, mine car easily causes the attachment pegs unhook to influence transportation because of jolting, colliding.In the tube-train hoisting transportation of gradient tunnel, also can cause derailing accident because of mine car breaks off relations.When realizing that not decoupling device of kick-up is overturned, set up complicated lock hook device.
Design goal of the present utility model is to overcome the weak point in the prior art, and provides a kind of simple in structure, and installing easily, and is easy for operation, and reliable operation can prevent the mine car attachment pegs lock hook self-locking device that attachment pegs breaks off relations effectively.
Design goal of the present utility model can reach by following measure:
Mine car attachment pegs lock hook self-locking device by be fixed on guide rail plate 1 on the outer wall of mine car casing end, be the bracing frame 2 of square frame shape, for the flexible connecting member, the self-locking block 4 that lift usefulness, be fixed on and connect pin-and-hole other bearing pin frame 5 and bearing pin 6 on the mine car frame and form.The top edge of bracing frame 2 is enclosed within guide rail plate 1 and the formed framework of car wall and links with an end of flexible connecting member, and its underpart links with self-locking block 4.Self-locking block 4, is had on the self-locking block 4 for blocking the bayonet socket of mine car attachment pegs 8 upper ends on bearing pin frame 5 by bearing pin 6 hinge joints.
Design goal of the present utility model can also reach by following measure:
The cross-sectional plane of the top edge of the bracing frame 2 of this device is circular, cooperate for no gap with the bottom of guide rail plate 1 and the formed framework of car wall, when the top of bracing frame 2 was lifted to guide rail plate framework top by flexible connecting member, the extended line of its side line of centers was in the mine car Che Biyi side of the axial line of bearing pin 6.
The bracing frame 2 of this device has an intermediate transverse girder, is " day " font, adopts connection chain 3 for the flexible connecting member that lifts usefulness, and the annulus at an end of connection chain 3 and the binding of the intermediate transverse girder of bracing frame 2, its other end and mine car attachment pegs 8 tops is connected.
Compared with the prior art the utility model has following advantage:
1. simple in structure, reliable operation, easy for operation, can prevent effectively that attachment pegs from breaking off relations.
2. the processing installing is simple, and cost of manufacture is low.
3. can realize not decoupling device of kick-up overturning easily.
The drawing of accompanying drawing is described as follows:
Fig. 1: the utility model structural representation front view
Fig. 2: the utility model structural representation birds-eye view
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1, Fig. 2 show composition of the present utility model.It is installed on the mine car vehicle frame, by the hole of attachment pegs 8, be made up of guide rail plate 1, bracing frame 2, connection chain 3, self-locking block 4, bearing pin frame 5, bearing pin 6 and spring cotter 7 thereof, cushion block 9.
Guide rail plate 1 is welded on the outer wall of mine car casing end, bracing frame 2 usefulness round steel are made square frame and are welded a crossbeam and make it to be " day " font, and its top edge is enclosed within guide rail plate 1 and the formed framework of car wall, crossbeam links with an end binding, its underpart and the self-locking block 4 of connection chain 3 in the middle of it.Self-locking block 4 has on the self-locking block 4 for blocking the bayonet socket of mine car attachment pegs 8 upper ends by on bearing pin 6, the spring cotter 7 hinge joint bearing pin framves 5.The opposite side that bearing pin frame 5 is welded on the mine car vehicle frame, mine car connects the other Che Biyi side of pin-and-hole, connection pin-and-hole is welded with cushion block 9.The annulus at the other end of connection chain 3 and mine car attachment pegs 8 tops is connected.
The top edge of the bracing frame 2 of this device, cooperate for no gap with the bottom of guide rail plate 1 and the formed framework of car wall, when being near level attitude with assurance bracing frame 2, its top edge is subjected to certain Clamping force, when kick-up overturns, keep self-locking block 4 to be in self-locking state like this.
When the top of the bracing frame 2 of this device is lifted to guide rail sheet frame top by connection chain 3, the extended line of bracing frame 2 side line of centerss is in the mine car Che Biyi side of the axial line of bearing pin 6, be that to put on the moment of self-locking block 4 around bearing pin 6 axle center be counter-clockwise applied moment the lower end of bracing frame 2, face upward to keep self-locking block 4 to extract its bayonet socket of back in attachment pegs 8.
When operation of mine car bunching or winch traction, mine car attachment pegs 8 is in coupled position, and bracing frame 2 is horizontal, and self-locking block 4 is chain in coupled position with attachment pegs 8.When needs proposed attachment pegs 8, connection chain 3 was at first mentioned bracing frame 2, removed the self-locking state of self-locking block 4, and attachment pegs 8 proposes coupled position.When connecting once more, attachment pegs 8 is inserted linkage self-locking piece 4 and is together fallen, and the upper end of attachment pegs 8 is blocked by the bayonet socket of self-locking block 4, and bracing frame 2 is fallen level attitude simultaneously, is in self-locking state.
