[0049] As described in the background, the railway locomotive is a key part of the railway transportation system, and undertakes the task of transporting goods and passengers. The railway locomotive includes an air compressor and a main reservoir system for storing compressed air generated by the compressor to ensure stable and continuous supply of necessary air source when the brake or other pneumatic equipment is needed, to ensure the safety and smoothness of the railway locomotive operation.

[0050] In order to maintain the running state of the railway locomotive and the reliability of the brake system, it is necessary to regularly inspect and maintain each part of the locomotive. In this maintenance process, the main reservoir needs to be disassembled from the locomotive and transferred to a special maintenance area by a cart for detailed detection and repair.

[0051] However, when the main reservoir is transported by the cart, it is difficult to ensure the stability of the transportation. During the transfer transportation, due to uneven road surface or improper operation, the main reservoir may be subjected to jolt and impact, thereby causing damage problems such as cracks, thereby affecting the normal use of the main reservoir and affecting the overall safety of the railway locomotive.

[0052] To solve the above problems, the embodiment of the present application provides a transfer device, comprising a base; at least one limiting piece, which is arranged on the base and is matched with a to-be-transferred piece, the limiting piece being used for limiting the relative position between the to-be-transferred piece and the base; a wheel set, which is rotatably arranged at the bottom of the base; and at least one damping assembly, which is arranged on the base, one end of the damping assembly being connected with the limiting piece, and the damping assembly being configured to absorb the displacement change of the limiting piece relative to the base. The transfer device provided by the embodiment of the present application limits the position of the to-be-transferred piece through the limiting piece, prevents the to-be-transferred piece from falling out due to uneven road surface or acceleration and deceleration in the transfer and transportation process, absorbs the displacement change of the limiting piece relative to the base through the damping assembly, that is, absorbs the vibration energy generated in the transfer and transportation process, avoids rigid collision between the to-be-transferred piece, the limiting piece and the base, reduces the impact and vibration suffered by the to-be-transferred piece, and realizes stable and safe transportation.

[0053] The technical solutions of the embodiments of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the embodiments of the present application will be described below with reference to the drawings.

[0054] Please refer to Figures 1 to 3 The embodiment provides a transfer device, comprising: a base 100; at least one limiting piece 200, which is arranged on the base 100 and is matched with a to-be-transferred piece 10, the limiting piece 200 being used for limiting the relative position between the to-be-transferred piece 10 and the base 100; a wheel set 300, which is rotatably arranged at the bottom of the base 100; and at least one damping assembly 400, which is arranged on the base 100, one end of the damping assembly 400 being connected with the limiting piece 200, and the damping assembly 400 being configured to absorb the displacement change of the limiting piece 200 relative to the base 100.

[0055] Specifically, in the embodiment, the base 100 is used for carrying the limiting piece 200, the to-be-transferred piece 10 and the damping assembly 400, and is made of a solid and durable material to ensure the carrying capacity and stability of the base 100 as the basic support structure of the entire transfer device.

[0056] In an exemplary embodiment, the base 100 is a bottom plate made of steel to ensure the stability of the base 100.

[0057] In this way, by setting the base 100 in the form of a bottom plate, the production process is simple, and the production cost is saved.

[0058] In an exemplary embodiment, the base 100 is in the form of a frame composed of multiple aluminum alloy profiles, thereby saving manufacturing materials and production costs.

[0059] When the base 100 is in the form of a frame, adaptive construction can be performed according to actual needs, and the embodiment does not make any limitation on this. For example, the base 100 is constructed into a square structure by a plurality of aluminum alloy profiles, and a reinforcing rib connected to two opposite sides respectively is arranged in the square structure to ensure the stability of the entire base 100.

[0060] In addition, the embodiment does not make any limitation on the specific material and processing technology of the base 100, and adaptive selection can be performed according to actual needs.

[0061] Specifically, in the embodiment, the limiting piece 200 is arranged on the base 100 and is arranged in matching with the to-be-shifted piece 10, and the limiting piece 200 is used to limit the relative position between the to-be-shifted piece 10 and the base 100.

[0062] Specifically, the number of the limiting piece 200 can be multiple, and the installation position and number of the limiting piece 200 can be adaptively selected according to actual needs to support and limit the to-be-shifted piece 10, and the embodiment does not make any limitation on this.

[0063] At the same time, the specific shape of the limiting piece 200 can be adaptively set according to the shape of the to-be-shifted piece 10.

[0064] In an optional embodiment, the limiting piece 200 is arranged below the to-be-shifted piece 10 to support the to-be-shifted piece 10. The to-be-shifted piece 10 can be directly placed on the limiting piece 200, or the to-be-shifted piece 10 can be fixed on the limiting piece 200 through other fixing pieces. For example, a bandage is arranged on the limiting piece 200, and the two ends of the bandage are detachably connected to the two ends of the limiting piece 200, so as to fix the to-be-shifted piece 10 on the limiting piece 200.

[0065] Specifically, in the embodiment, the damping assembly 400 is arranged on the base 100.

[0066] Specifically, the embodiment does not make any limitation on the connection mode between the damping assembly 400 and the base 100, and adaptive selection can be performed according to actual needs.

[0067] In an exemplary embodiment, the damping assembly 400 is fixed on the base 100 by welding to ensure the stability of the connection between the damping assembly 400 and the base 100.

[0068] In an exemplary embodiment, the damping assembly 400 is fixed on the base 100 by a bolt, so as to realize detachable connection between the damping assembly 400 and the base 100, and the operator can maintain and repair the damping assembly 400 and the base 100.

[0069] Specifically, in the embodiment, one end of the damping assembly 400 is connected with the limiting piece 200 to absorb the displacement change of the limiting piece 200 relative to the base 100.

[0070] Specifically, the embodiment does not limit the connection mode between the damping assembly 400 and the limiting piece 200, and the connection mode can be selected adaptively according to actual needs.

[0071] In an exemplary embodiment, the limiting piece 200 and the damping assembly 400 are fixed by welding to ensure the stability of the connection between the limiting piece 200 and the damping assembly 400, and to avoid disengagement of the limiting piece 200 and the damping assembly 400 due to road bumps and the like.

[0072] In an exemplary embodiment, the limiting piece 200 and the damping assembly 400 are connected by screwing, clamping or other detachable connection modes, so as to facilitate maintenance of the damping assembly 400 and the limiting piece 200 by the operator.

[0073] By using the above technical solution, the position of the to-be-shifted piece 10 is limited by the limiting piece 200 to prevent the to-be-shifted piece 10 from falling out due to uneven road surface or acceleration and deceleration during the shifting and transporting process. The displacement change of the limiting piece 200 relative to the base 100 is absorbed by the damping assembly 400, that is, the vibration energy generated during the shifting and transporting process is absorbed, and rigid collision between the to-be-shifted piece 10, the limiting piece 200 and the base 100 is avoided, so as to reduce the impact and vibration of the to-be-shifted piece 10, and stable and safe shifting and transporting is achieved.

[0074] In an optional embodiment, the damping assembly 400 includes a support 410 arranged on the base 100, the support 410 has an accommodating cavity formed therein; a connecting piece 420, part of which is located in the accommodating cavity, one end of the connecting piece 420 extends out of the accommodating cavity and is connected with the limiting piece 200; and an elastic piece 430 arranged in the accommodating cavity, and two ends of the elastic piece 430 abut against the connecting piece 420 and the bottom of the accommodating cavity, respectively.

The support 410 has the accommodating cavity formed therein, the elastic piece 430 is arranged in the accommodating cavity, and one end of the connecting piece 420 is located in the accommodating cavity and abuts against the elastic piece 430, and the other end is connected with the limiting piece 200. Thus, the elastic deformation capacity of the elastic piece 430 is used to absorb and store vibration energy, and the vibration energy is gradually released after the vibration ends, thereby effectively reducing the influence of the vibration on the to-be-shifted piece 10 and ensuring the stability during the shifting and transporting process.

[0076] In the embodiment, the elastic piece 430 is a spring.

[0077] In other alternative embodiments, the elastic member 430 can also be made of other materials having good elastic deformation ability, such as rubber, spring steel, etc.

[0078] In the present embodiment, the limiting member 200 is connected to the end of the connecting member 420 extending out of the accommodating cavity, and the to-be-transferred member 10 is arranged on the limiting member 200. When jolting or shaking occurs, the limiting member 200 drives the connecting member 420 to move in the height direction of the accommodating cavity, thereby extruding or stretching the elastic member 430, so as to store vibration energy in the elastic member 430, reduce the impact of jolting and shaking on the to-be-transferred member 10, and ensure the stability of the to-be-transferred member 10 during the transfer and transportation.

[0079] In an alternative embodiment, the transfer device further comprises an anti-skid member 500 arranged on the limiting member 200 and abutting against the to-be-transferred member 10.

At the same time, the anti-skid member 500 can be made of a material having a certain elastic deformation ability, which can absorb a certain degree of vibration energy, thereby further enhancing the stability of the to-be-transferred member 10 during transfer and transportation.
