Description

Technical Field

[0001] The utility model relates to the technical field of mine cars, and particularly relates to a side-dumping mine car with a pin anti-detachment structure. Background Art

[0002] The side-dumping mine car is the main equipment for long-distance transportation in the horizontal roadway of the mine. It has a high running speed, a large adhesive weight, and the use environment is metal and non-metal mines. The walking part adopts a four-axle and eight-wheel mechanism, and a bogie structure is adopted between the axle and the car body frame, which reduces the turning radius of the mine car, effectively reduces the wear between the wheels and the track, and at the same time avoids the occurrence of the phenomenon of the mine car derailing. The connecting device between the mine cars is designed with a rubber buffer, which effectively reduces the impact force during the operation of the mine car.

[0003] During the unloading process, the movement of the contact point between the unloading wheel and the unloading curved rail is simultaneously composed of two movements: one is the rotational movement of the unloading wheel around the center of the rotating shaft between the moving car body 2 and the carriage 1, and the other is the horizontal linear movement of the unloading wheel along the advancing direction of the mine car; the center of the rotating shaft between the moving car body 2 and the carriage 1 adopts four pins 5 (one end of the pin 5 passes through the through holes provided on the carriage mounting plate 3 and the car body mounting plate 4, the lower end of the pin clamping plate 6 is clamped in the card slot 7 provided on the pin 5, and is fixedly connected to the carriage mounting plate 3 through bolts) to bear all the unloading forces. Due to the large impact and vibration during the actual use process, it is easy for the pin clamping plate 6 to loosen and fall off, and finally the pin 5 is disengaged, which will cause the carriage 1 to deform. Therefore, the present application provides a side-dumping mine car with a pin anti-detachment structure to meet the requirements. Summary of the Utility Model

[0004] The purpose of the present application is to provide a side-dumping mine car with a pin anti-detachment structure, which is used to solve the technical problem that the pins installed through the pin clamping plates in the prior art are prone to fall off.

[0005] To achieve the above purpose, the present application provides the following technical solutions: A side-dumping mine car with a pin anti-detachment structure includes a carriage, a moving car body, a carriage mounting plate, a car body mounting plate, and a pin. It further includes a block welded to the end of the pin, and both ends of the block extend beyond the pin by a certain distance. Triangular welding cavities are provided on both the upper and lower sides of the side of the block close to the pin.

[0006] As a preferred implementation manner in this embodiment, support rods are fixed to both ends of the block, and one end of the support rod close to the carriage mounting plate is in sliding contact with the side end of the carriage mounting plate.

[0007] As a preferred implementation manner in this embodiment, balls are installed at the ends of the two support rods close to the carriage mounting plate, and the balls are in rolling contact with the side end of the carriage mounting plate.

[0008] As a preferred implementation manner in this embodiment, the support rod is set as a telescopic rod, and a buffer spring is installed in the inner cavity of the telescopic rod.

[0009] As a preferred implementation manner in this embodiment, it further includes a pin shaft clamping plate. The lower end of the pin shaft clamping plate is clamped in a clamping groove provided on the pin shaft, and the pin shaft clamping plate is fixedly connected to the carriage mounting plate through no less than two groups of bolts.

[0010] In summary, the technical effects and advantages of the present utility model are as follows:

[0011] The structure of the present utility model is reasonable. By providing a stop block on one side end of the pin shaft, the part of the stop block exceeding the pin shaft can form a block with the carriage mounting plate, which can effectively prevent the pin shaft from falling off. There are two welding cavities arranged vertically on the stop block, which can make the stop block and the pin shaft form two welds, improving the welding firmness of the stop block. The triangular welding cavity can increase the welding area, further improving the welding firmness and also playing a role in accommodating the melted solder, preventing the solder from dripping.

[0012] In the present utility model, support rods are fixed at both ends of the stop block, which can prevent the pin shaft from moving horizontally and improve the service life of the component.

[0013] In the present utility model, balls are installed at the ends of the two support rods close to the carriage mounting plate, which can reduce the friction between the support rods and the carriage mounting plate, avoid frictional wear of the support rods, and be beneficial to the horizontal stability of the pin shaft, that is, no horizontal movement occurs.

[0014] In the present utility model, the support rod is set as a telescopic rod, and a buffer spring is installed in the inner cavity of the telescopic rod. Buffering can be carried out by setting the buffer spring, which can buffer the collision between the stop block and the carriage mounting plate and improve the service life of the component.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: Refer to Figures 1-3 A side-dumping mine car with a pin shaft anti-detachment structure shown in the figure, including a carriage 1, a movable vehicle bottom 2, a carriage mounting plate 3, a vehicle bottom mounting plate 4, and a pin shaft 5. It further includes a stop block 8 welded to the end of the pin shaft 5, and both ends of the stop block 8 extend beyond the pin shaft 5 by a certain distance. On both the upper and lower sides of the side of the stop block 8 close to the pin shaft 5, there are welding cavities 9 with a triangular structure.

[0024] By providing a stop block 8 on one side end of the pin shaft 5, the part of the stop block 8 that extends beyond the pin shaft 5 can form a block with the carriage mounting plate 3, effectively preventing the pin shaft 5 from falling off. There are two welding cavities 9 arranged vertically on the stop block 8, which can make the stop block 8 and the pin shaft 5 form two welds, improving the welding firmness of the stop block 8. The welding cavity 9 with a triangular structure can increase the welding area, further improving the welding firmness while also accommodating the melted solder, preventing the solder from dripping during the welding process and avoiding solder waste.

[0025] As a preferred implementation manner in this embodiment, as shown in Figure 3 In the figure, support rods 10 are fixed to both ends of the stop block 8, and the end of the support rod 10 close to the carriage mounting plate 3 is in sliding contact with the side end of the carriage mounting plate 3.

[0026] After the original pin shaft 5 is installed on the mine car, the plug-in end of the original pin shaft 5 is some distance away from the side end of the carriage mounting plate 3, which may easily cause the pin shaft 5 to move laterally when the mine car is running or unloading or loading, and cause the protruding part of the block 8 to collide frequently with the carriage mounting plate 3 (frequent collisions may easily cause metal fatigue). Therefore, a support rod 10 is provided to prevent the pin shaft 5 from moving laterally and increase the service life of the components.

[0027] It should be noted that the lateral movement of the pin 5 will also aggravate the wear of the pin 5 .

[0028] As a preferred implementation in this embodiment, Figure 4 As shown, balls 11 are installed on the ends of the two support rods 10 close to the carriage mounting plate 3, and the balls 11 are in rolling contact with the side ends of the carriage mounting plate 3.

[0029] Since no limiting structure is set for the rotation of the pin shaft 5, the pin shaft 5 rotates during the operation of the mine car. Therefore, the ball 11 is set to reduce the friction between the support rod 10 and the car mounting plate 3, thereby avoiding friction loss of the support rod 10 and facilitating the lateral stability of the pin shaft 5, i.e., preventing lateral movement.

[0030] As a preferred implementation in this embodiment, Figure 4 As shown, the support rod 10 is configured as a telescopic rod, and a buffer spring 12 is installed in the inner cavity of the telescopic rod.

[0031] A buffer spring 12 can be provided to provide buffering, so as to buffer the collision between the stopper 8 and the carriage mounting plate 3 and increase the service life of the components.

[0032] As a preferred implementation in this embodiment, Figure 2 As shown, it also includes a pin clamping plate 6, the lower end of which is clamped in a clamping groove 7 provided on the pin 5, and the pin clamping plate 6 is fixedly connected to the carriage mounting plate 3 by no less than two groups of bolts.

[0033] The stopper 6 can be used alone or in conjunction with the original pin pull plate 6. When used in conjunction, when the pin pull plate 6 becomes loose and falls off, the stopper 8 prevents the pin 5 from falling off.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
