Abstract
The utility model discloses a flat car disconnection prevention apparatus for coal mine, and the vehicle body forms the integral structure of the flat car disconnection prevention apparatus. The vehicle body employs an I-steel, a channel steel and a steel plate, which are welded together, and wheels are installed on the bottom of the vehicle body. An upper towing plate is installed on the upper surface at two ends of the vehicle body, and a lower towing plate is installed on the lower surface at the two ends of the vehicle body. A latch is installed at two ends of the vehicle body, and the bottom of the latch is provided with a disconnection prevention bolt. A disconnection prevention bolt is arranged in the center of a disconnection prevention ring, which is installed on the bottom of latch. A traction tri-loop chain has two coupling ends, of which one is connected to the tail portion of a vehicle body, and the other is connected to the head portion of the next flat car. The flat car disconnection prevention apparatus is safe and reliable for operation and convenient for maintenance, and the wheels are sealed in a labyrinth sealing manner, thereby effectively preventing entering of coal dust and sandy soil.
Description
Technical field
The utility model relates to flat truck accessory technical field, especially a kind of coal mine platform lorry anti-drop device.
Background technology
Flat truck is mainly used in coal mine, underground transportation heavy wares is as the special narrow gage vehicle of hydraulic support, coalcutter or the main equipment after disintegrating.Flat truck uses the traction of locomotive or winch, between car and car, is connected with monocycle chain or ring chain, makes it can smooth running on guide rail.But ring chain or monocycle chain rely on latch to be connected with vehicle, if there is no anti-drop device in operational process, latch is once deviate to cause vehicle to move; If latch deviates to occur in ramp, will cause very large accident, so, anti-drop device be flat bed transport vehicle must device.And anti-drop device in the past adopts latch below to use nut anti-falling, although the method is reliable and secure, there is inconvenience, speed is slow, and under harsh environment the shortcoming such as not easy to operate.In use, tend to appear under harsh environment cannot operate, workman use inconvenience etc. shortcoming.Therefore, for solving above-mentioned deficiency, a kind of coal mine platform lorry anti-drop device technology of special release, this anti-drop device adopts labyrinth anticreep method, has advantages such as using simple, convenient, fast, high quality, high safety.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of coal mine platform lorry anti-drop device.
For realizing this technical purpose, scheme of the present utility model is: a kind of coal mine platform lorry anti-drop device, comprise vehicle body main body, wheel, upper towing plate, lower towing plate, latch, anticreep bolt, anti-decylization, anticreep bolt is by mouth, traction ring chain, described vehicle body main body forms integral structure of the present utility model, vehicle body main body adopts I-beam section, channel-section steel and Plate Welding form, the bottom of vehicle body main body is provided with wheel, described upper towing plate is arranged on the upper surface at vehicle body main body two ends, described lower towing plate is arranged on the lower surface at vehicle body main body two ends, described latch is arranged on the two ends of vehicle body main body, latch bottom is provided with anticreep bolt, in the middle of described anti-decylization, be provided with anticreep bolt by mouth, anti-decylization is arranged on the bottom of latch, described traction ring chain has two connection ends, one end is connected to vehicle body main body afterbody, the other end connects the stem of next flat truck.
As preferably, on described upper towing plate and lower towing plate, be equipped with anticreep bolt by mouth.
As preferably, the two ends of described vehicle body main body are equipped with shock absorber, in this device, energy disperser are installed, available buffer and absorb the impulsive force from flat truck direction of travel.
The anti-decylization that the utility model adopts has the blocking function of spiral groove type, can prevent that connecting bolt from deviating from voluntarily, make the safer, more reliable of mine car operation, wheel component adopts mounting or dismounting open architecture form easy, easy to maintenance, be convenient to maintenance, wheel be sealed into labyrinth seal, can effectively prevent that coal dust, sand from invading, device high quality, uses high safety.
