Description
Technical field:
The utility model belongs to mine car latch technical field.
Background technology:
Mine car is the main transported material instrument in mine, utilizes latch and loop chain that mine car one is saved during transportation and links up.At present, the latch that mine car connecting bridge in down-hole uses on the coal mine normally adopts special chain, and chain one end is enclosed within on the handheld ring of latch, and the other end is welded on the mine car car body.Because the use amount of mine car is big, chain materials demand amount is many, and latch is in use often lost during not prison welding; Latch does not possess latch anticreep regulating device in addition, also can cause latch to eject sometimes, causes derailing accident.
The utility model content:
The purpose of this utility model provides a kind of anti-lost, anti-disconnection, safe and reliable mine car prevents losing latch with anticreep.
To achieve these goals, the utility model comprises: handheld ring, fixed cover, swivel pin, the seat of meeting and discussing, stub, lower plate, middle plate, upper plate, lower plate, middle plate, upper plate fixed interval respectively is arranged on the car body termination, be fixedly welded with the seat of meeting and discussing in the upper plate outer end, at the seat of meeting and discussing, middle plate, have the stub jack in the middle of the lower plate, handheld ring and stub fuse, stub is inserted in the stub jack, the seat of meeting and discussing is provided with fixed cover, have plug helix on the fixed cover, top at stub is provided with swivel pin, swivel pin cooperates with the fixed cover rotation, be inlaid with in the lower end of stub one side and anti-lose pin, have keyway with a corresponding side of middle plate stub jack, prevent losing pin and keyway is complementary in lower plate.
Like this, mine car is when normal transportation by regular carriers, and the fixing loop chain of mine car one end is through on the stub and between upper plate and middle plate, stub is under the effect of its gravity, and swivel pin is in fixed cover spiral fluted extreme lower position all the time, owing to there is not rotational force, stub is not scurried on not understanding, and has realized the function of anticreep.When unsnaping mine car, utilize handheld ring to rotate up and lift stub, because correspondence one side at lower plate, middle plate stub jack has keyway, preventing losing pin can be smoothly by middle plate and lower plate, and only be processed with the stub jack on the termination of meeting and discussing and do not have keyway, add anti-outstanding length of losing pin greater than stub jack size, so no matter loop chain is in coupled condition or in disengaged condition, latch can not separate all the time with the seat of meeting and discussing, thereby realizes the anti-function of losing.The operator is by the rotation handheld ring, under fixed cover spiral fluted directional tagging, controlled latch about, the excision that realizes ring chain be connected.Have characteristics such as anti-lost, anti-ly disconnect, safe and reliable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the integral structure scheme drawing of mine car.
