Description

Technical Field

[0001] The utility model belongs to the technical field of car unloading machines, and relates to a supporting sliding device, in particular to a supporting sliding device for a telescopic main arm of a car unloading machine positioning vehicle with a buffering function. Background Art

[0002] The unloading machine positioning car is a key equipment for the tipping unloading operation of the unloading machine. After the open car allocated by the railway enters the unloading machine track and completes the alignment, the unloading machine positioning car runs to the starting position of the car shifting, and its telescopic main arm extends and is connected to the connection part of the train car through the hook head. After the connection, the positioning car moves to the working position of the unloading platform, and the train car moves with the positioning car. When the positioning car shifts the train car to the working position of the unloading platform, the positioning car stops running. At this time, the wheel clamp corresponding to the train car clamps the train car and fixes it. After the fixation is completed, the telescopic main arm of the positioning car retracts. After retracting into position, the positioning car returns to the starting position of the car shifting to prepare for the next cycle of car shifting operation. When entering the next cycle, its operation method is the same as the previous cycle. After multiple cycles of operation until this operating train enters the last cycle, in the last cycle, the positioning car uses the tail car arm to shift the last car. After the operation is completed, the positioning car returns to the starting position. During the operation, if the positioning vehicle does not position the carriage correctly and cannot perform the unloading operation, it will directly affect the operating efficiency of the unloading machine.

[0003] When the positioning vehicle is operating the railway's allocated open wagon, when the positioning vehicle's telescopic main arm is extended, the front of the telescopic main arm will sink after it is fully extended due to the heavy hook head at the front of the telescopic main arm, and the rear of the telescopic main arm will rise accordingly. Afterwards, when the telescopic main arm retracts to the horizontal position, the raised rear part of the telescopic main arm moves downward to the horizontal position. During this process, the downward movement of the telescopic main arm will cause an impact on the rear sliding roller at its lower part. The long-term impact will cause the rear sliding roller to be damaged, and the rear sliding roller in this part needs to be replaced regularly, which is relatively wasteful of spare parts costs. If it is not replaced regularly, it may also cause the positioning vehicle's telescopic main arm to move sluggishly, which to a certain extent affects the working efficiency. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a telescopic main arm supporting sliding device for a car unloader positioning vehicle with a buffering function, so as to overcome the problems raised in the above-mentioned background technology.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A telescopic main arm support sliding device for a car unloading machine positioning vehicle with a buffering function is characterized in that it includes a fixed base, a buffering mechanism, a fixed end cover and a sliding mechanism, the buffering mechanisms are symmetrically installed at the front and rear ends of the fixed base, the fixed end covers are supported and installed on the two buffering mechanisms, and the sliding mechanism is installed on the fixed end cover at the position corresponding to the buffer mechanism.

[0007] Moreover, the buffer mechanism includes a buffer spring, an upper mounting groove of the buffer spring and a lower mounting groove of the buffer spring. The lower mounting groove of the buffer spring is installed on the upper end surface of the fixed base, and the upper mounting groove of the buffer spring is installed on the lower end surface of the fixed end cover. The buffer spring limiter is installed between the upper mounting groove of the buffer spring and the lower mounting groove of the buffer spring.

[0008] Moreover, the sliding mechanism includes a sliding roller and a bearing seat. The sliding rollers are symmetrically installed on the fixed end cover at the position corresponding to the buffer spring. Each sliding roller is rotatably installed on the fixed end cover through the bearing seat.

[0009] The advantages and positive effects of the utility model are:

[0010] This buffering support sliding device for the telescopic main arm of the unloader positioning vehicle is installed in front of the rear sliding roller, below the telescopic main arm and in the middle and rear part, above the rear sliding roller. When the telescopic main arm is in the horizontal position, it provides support and assists in the sliding of the rear part. When the telescopic main arm retracts, the rear part of the telescopic main arm moves from a high position to a horizontal position. The support sliding device can pre-emptively buffer the downward impact caused by the telescopic main arm, reducing the downward movement speed of the telescopic main arm, reducing the impact of the telescopic main arm on the rear sliding roller, and significantly reducing the possibility of damage to the rear sliding roller. This saves spare parts costs and maintenance man-hours to a certain extent, and improves operational efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0018] A telescopic main arm supporting sliding device for a car unloading machine positioning vehicle with a buffering function, the innovation of which lies in: comprising a fixed base 1, a buffering mechanism, a fixed end cover 5 and a sliding mechanism, the buffering mechanisms being symmetrically installed at the front and rear ends of the fixed base, the fixed end covers being supported and installed on the two buffering mechanisms, and the sliding mechanism being installed on the fixed end cover at a position corresponding to the buffering mechanism.

[0019] The buffer mechanism includes a buffer spring 3, an upper buffer spring mounting slot 4, and a lower buffer spring mounting slot 2. Two lower buffer spring mounting slots are symmetrically mounted on the front and rear ends of the upper end face of the fixed base, and two upper buffer spring mounting slots are symmetrically mounted on the front and rear ends of the lower end face of the fixed end cover. The two buffer spring limiters are installed between the upper and lower buffer spring mounting slots. The upper and lower buffer spring mounting slots serve to limit the buffer springs, ensuring the stability of the operation of the utility model.

[0020] The sliding mechanism includes sliding rollers 7 and bearing blocks 6. Two sliding rollers are symmetrically mounted on the fixed end cap, corresponding to the buffer springs. Each sliding roller is rotatably mounted on the fixed end cap via the bearing blocks. As the rear portion of the telescopic boom descends, the sliding rollers provide sliding support, preventing wear on the boom.

[0021] The utility model is installed at the lower middle rear part of the telescopic main arm 9 of the positioning vehicle of the unloading machine, and plays a role in buffering and assisting the sliding of the rear part of the telescopic main arm. When the telescopic main arm of the positioning vehicle is extended, the front part of the telescopic main arm will sink after being extended to its full position due to the heavy hook head 8 at the front of the telescopic main arm, and the rear part of the telescopic main arm will rise accordingly. At this time, the telescopic main arm is supported by the hook head, the positioning vehicle steel structure 12 and the front sliding roller 11. Afterwards, when the telescopic main arm retracts to the horizontal position during the retraction process, the raised rear part of the telescopic main arm moves downward to the horizontal position. During this process, the downward movement of the telescopic main arm will cause an impact on the rear sliding roller 10 at its lower part. Long-term impact will cause damage to the rear sliding roller, and the rear sliding roller in this part needs to be replaced regularly. The device is installed in the front part of the rear sliding roller, at the middle and rear part below the telescopic main arm and higher than the rear sliding roller. When the telescopic main arm moves downward, the utility model can buffer the impact caused by it in advance, so that the downward movement speed of the telescopic main arm is reduced, the impact of the telescopic main arm on the rear sliding roller is reduced, and the possibility of damage to the rear sliding roller is greatly reduced. To a certain extent, the spare parts cost and maintenance man-hours are saved, and the working efficiency is improved.

[0022] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
