[0040] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0041] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0042] A locomotive is commonly known as a locomotive, which is used to pull or push railway vehicles. A locomotive may include a car body and a bogie. The car body of some locomotives may be mounted on the bogie through a spring system. A driving device for generating traction and a braking device for generating braking force are mounted on the bogie. A traction seat is mounted on the car body. The driving device and the braking device are connected to the traction seat through a traction rod, so as to transmit the traction and braking forces to the car body through the traction rod and the traction seat.

[0043] Figure 1 A schematic diagram of a locomotive traction seat mounting device supporting a traction seat provided by an embodiment of the present disclosure.

[0044] like Figure 1 As shown, in some locomotives, the traction seat 100 can be detachably mounted on the vehicle body by bolts. Specifically, the traction seat 100 can include a vehicle body mounting plate 110, a traction rod mounting plate 120 and a protective plate 130. The protective plates 130 are fixedly mounted on both ends of the vehicle body mounting plate 110 in the length direction. The protective plates 130 extend below the vehicle body mounting plate 110. The upper end of the traction rod mounting plate 120 is fixedly connected to the bottom surface of the vehicle body mounting plate 110. The two ends of the traction rod mounting plate 120 in the length direction extend along the length direction of the vehicle body mounting plate 110 and are respectively connected to the protective plates 130 at both ends of the vehicle body mounting plate 110. The traction rod mounting plate 120 is located in the middle of the width direction of the vehicle body mounting plate 110. The traction rod mounting plate 120 has a traction hole for mounting the traction rod. The vehicle body mounting plate 110 has a mounting hole 111 and a positioning hole 112. There can be multiple mounting holes 111 and positioning holes 112. For example, the vehicle body mounting plate 110 may have four mounting holes 111 distributed in a matrix, two rows of mounting holes 111 are respectively located on both sides of the drawbar mounting plate 12 in the width direction of the vehicle body mounting plate 110, and a positioning hole 112 is provided between two mounting holes 111 in each row. The vehicle body mounting plate 110 can be detachably mounted on the vehicle body by bolts passing through the mounting holes 111.

[0045] When the locomotive is overhauled, the traction seat 100 needs to be removed for inspection and repair, and then installed on the vehicle body after the inspection is completed. Since the part of the vehicle body for installing the traction seat 100 is at the bottom of the vehicle body, it is blocked by the vehicle body and it is impossible to use a crane or other lifting tool to lift the traction seat 100 and move it to the installation position at the bottom of the vehicle body.

[0046] In the related art, manual lifting is often used to install the fifth wheel onto the vehicle body. Since a single fifth wheel is heavy, usually more than 60 kg, this method requires at least two operators to lift the fifth wheel and move it to the installation position so that the mounting holes on the vehicle body mounting plate are aligned with the corresponding assembly holes on the vehicle body. The operator who lifts the fifth wheel needs to keep the fifth wheel at the installation position, and then another operator installs bolts under the fifth wheel to fix the fifth wheel to the vehicle body.

[0047] In the related art, it takes a large number of operators to install the traction seat on the vehicle body, and the labor intensity of the operators is relatively high. In addition, since it takes a long time to lift the traction seat, the operators who lift the traction seat are prone to fall after being tired, causing personal injury and device damage, which poses a great safety hazard. In addition, the working space under the locomotive body is relatively small, and it is difficult for the operators who lift the traction seat to move and stand. It is also difficult to move the traction seat to the installation position, resulting in a long operation time and a greater safety risk.

[0048] Figure 2 A schematic diagram of a locomotive traction seat installation device from one perspective provided by an embodiment of the present disclosure, Figure 3 A schematic diagram of a locomotive traction seat mounting device from another perspective provided in an embodiment of the present disclosure.

[0049] like Figure 2 , Figure 3 As shown, and see Figure 1 Based on this, the embodiment of the present application provides a locomotive traction seat installation device, which includes a universal wheel group 500, a base 200, a lifting mechanism 300 and a support assembly 400. The universal wheel group 500 is installed at the bottom of the base 200, and the support assembly 400 is installed above the base 200 through the lifting mechanism 300. The support assembly 400 is used to support the vehicle body mounting plate 110 of the traction seat 100 and expose the mounting hole 111 of the vehicle body mounting plate 110 supported by it. A positioning column 600 is fixedly connected to the top surface of the support assembly 400, and the positioning column 600 is used to penetrate the positioning hole 112 of the vehicle body mounting plate 110 to limit the traction seat 100 supported by the support assembly 400 from moving along the top surface of the support assembly 400.

[0050] It is understandable that the lifting mechanism 300 can be used to adjust the vertical spacing between the base 200 and the support assembly 400. When the traction seat 100 needs to be installed on the vehicle body, the locomotive traction seat installation device can be moved to a relatively open position first, and then the traction seat 100 can be placed on the support assembly 400 by manpower or lifting tools such as a crane, and the positioning column 600 is inserted into the positioning hole 112 of the vehicle body mounting plate 110, and then the locomotive traction seat installation device with the traction seat 100 is moved to the lower part of the installation position of the vehicle body through the universal wheel group 500, and the traction seat 100 placed on the support assembly 400 is lifted by the lifting mechanism 300. After the traction seat 100 is close to the installation position of the vehicle body, for example, when the traction seat 100 is 10 meters away from the vehicle body, the traction seat 100 is lifted. When the distance is about 100 mm, the position of the locomotive traction seat installation device on which the traction seat 100 is placed is finely adjusted by the universal wheel set 500 so that the installation hole 111 is opposite to the corresponding assembly hole on the vehicle body, and then the traction seat 100 is further lifted to the installation position by the lifting mechanism 300. The operator inserts the bolts into the exposed installation holes 111 and the corresponding assembly holes, and tightens them with nuts to fix the traction seat 100 to the vehicle body. The support assembly 400 is then lowered by the lifting mechanism 300, and the locomotive traction seat installation device is moved out from under the vehicle body by the universal wheel set 500, and the installation of the traction seat 100 and the vehicle body is completed.

[0051] In this way, after the traction seat 100 is placed on the support assembly 400, only one operator is required to move, lift and install the traction seat 100 with the vehicle body, and the number of operators required for the installation of the traction seat 100 with the vehicle body is small. In addition, the traction seat 100 is supported by the support assembly 400, and the traction seat 100 supported by the support assembly 400 can be moved by the universal wheel set 500, and the traction seat 100 supported by the support assembly 400 can be lifted by the lifting mechanism 300, which can reduce the labor intensity of the operators and help improve the efficiency and safety of the operation. In addition, the operator located at the side of the vehicle body can move the traction seat 100 supported by the support assembly 400 to the lower part of the installation position by pushing the base 200. When moving the traction seat, the operator does not need to be located under the vehicle body, and it is easier and safer to move the traction seat 100 to the installation position. Furthermore, after the positioning column 600 is inserted into the positioning hole 112 of the fifth wheel 100, the fifth wheel 100 supported by the support assembly 400 is not easy to fall off the support assembly 400. The fifth wheel 100 is installed on the vehicle body through the locomotive fifth wheel installation device, and the risk of safety accidents is small.

[0052] In a possible implementation, two spaced-apart positioning posts 600 are fixedly connected to the top surface of the support assembly 400 , and each positioning post 600 is used to pass through a positioning hole 112 of the vehicle body mounting plate 110 .

[0053] In this way, the fifth wheel 100 supported by the support assembly 400 can be restricted from rotating on the top surface of the support assembly 400, the support of the fifth wheel 100 by the support assembly 400 is stable, and the movement, lifting and installation of the fifth wheel 100 are safer.

[0054] In a possible embodiment, the support assembly 400 includes a bearing plate 410 and a first support member 420 and a second support member 430 fixedly connected to the top surface of the bearing plate 410. The bearing plate 410 is installed above the base 200 through the lifting mechanism 300. The first support member 420 and the second support member 430 are spaced apart on the top surface of the bearing plate 410. The top surfaces of the first support member 420 and the second support member 430 are both fixedly connected with a positioning column 600. The first support member 420 and the second support member 430 are both used to penetrate the space between the two protective plates 130 of the traction seat 100 and support the vehicle body mounting plate 110. The space between the first support member 420 and the second support member 430 is used to accommodate the traction rod mounting plate 120 of the traction seat 100.

[0055] In this way, the first support member 420 and the second support member 430 avoid the protective plate 130 and the traction rod mounting plate 120 that protrude downward from the vehicle body mounting plate 110, so that the traction seat 100 can be placed more stably on the support assembly 400. The traction seat 100 supported by the support assembly 400 is not easy to move, and the support assembly 400 supports the traction seat 100 more stably.

[0056] It can be understood that the supporting surfaces of the first support member 420 and the second support member 430 for supporting the vehicle body mounting plate 110 are coplanar.

[0057] Exemplarily, the supporting plate 410 may be a rectangular plate.

[0058] In a possible embodiment, the first support member 420 includes a first side vertical plate 421, a first support plate 422, and at least two first ribs 423 arranged at intervals along the length direction of the first side vertical plate 421, and the second support member 430 includes a second side vertical plate 431, a second support plate 432, and at least two second ribs 433 arranged at intervals along the length direction of the second side vertical plate 431.

[0059] The lower ends of the first side upright plate 421 and the second side upright plate 431 are fixedly connected to the top surface of the supporting plate 410 , and the second side upright plate 431 is opposite to the first side upright plate 421 on one side in the thickness direction of the first side upright plate 421 and is spaced apart.

[0060] The top end of the first side upright plate 421 is fixedly connected to one end of the first support plate 422 toward the second side upright plate 431, the first rib plate 423 is located on the side of the first side upright plate 421 away from the second side upright plate 431, the upper end of the first rib plate 423 is fixedly connected to the first support plate 422, the lower end of the first rib plate 423 is fixedly connected to the bearing plate 410, and the end of the first rib plate 423 toward the first side upright plate 421 is fixedly connected to the first side upright plate 421.

[0061] The top end of the second side upright plate 431 is fixedly connected to one end of the second support plate 432 toward the first side upright plate 421, the second rib plate 433 is located on the side of the second side upright plate 431 away from the first side upright plate 421, the upper end of the second rib plate 433 is fixedly connected to the second support plate 432, the lower end of the second rib plate 433 is fixedly connected to the bearing plate 410, and the end of the second rib plate 433 toward the second side upright plate 431 is fixedly connected to the second side upright plate 431.

[0062] The top surfaces of the first support plate 422 and the second support plate 432 are fixedly connected with positioning columns 600. The first support plate 422 and the second support plate 432 are both used to support the vehicle body mounting plate 110. The lengths of the first support plate 422, the first side upright plate 421, the second support plate 432 and the second side upright plate 431 are all smaller than the minimum interval between the two protective plates 130 of the traction seat 100. The interval between the first side upright plate 421 and the second side upright plate 431 is used to accommodate the traction rod mounting plate 120.

[0063] Thus, the first support member 420 and the second support member 430 are light in weight and can provide a large supporting force, and the first support member 420 and the second support member 430 are not easily crushed. In addition, the first support plate 422 and the second support plate 432 support the fifth wheel 100, and the support is also relatively stable.

[0064] It can be understood that the supporting surfaces of the first support plate 422 and the second support plate 432 for supporting the vehicle body mounting plate 110 are coplanar.

[0065] In some examples, the lifting mechanism 300 includes a telescopic rod 310 , the lower end of the telescopic rod 310 is fixedly connected to the top surface of the base 200 , and the upper end of the telescopic rod 310 is fixedly connected to the bottom surface of the support assembly 400 .

[0066] In a possible embodiment, the lifting mechanism 300 includes three telescopic rods 310 distributed in a triangular shape on the top surface of the base 200, the lower end of each telescopic rod 310 is fixedly connected to the top surface of the base 200, and the upper end of each telescopic rod 310 is hinged to the bottom surface of the support assembly 400.

[0067] In this way, the angle of support assembly 400 is adjustable, so that the angle of fifth wheel 100 supported by support assembly 400 is adjustable, and the angle of support assembly 400 can be adjusted according to the actual state of the vehicle body and the flatness of the ground, which helps to eliminate the problem of difficulty in aligning mounting holes 111 on fifth wheel 100 with corresponding assembly holes on the vehicle body due to the tilt of the vehicle body or the uneven ground, thereby facilitating the installation of fifth wheel 100 and the vehicle body.

[0068] It can be understood that the three telescopic rods 310 distributed in a triangle are spaced apart from each other, and each telescopic rod 310 can be independently telescopic.

[0069] When the support assembly 400 includes a bearing plate 410 , the upper end of the telescopic rod 310 may be hinged to the bottom surface of the bearing plate 410 via a hinge seat.

[0070] In one possible embodiment, the lifting mechanism 300 includes four telescopic rods 310 distributed in a matrix on the top surface of the base 200, the lower end of each telescopic rod 310 is fixedly connected to the top surface of the base 200, and the upper end of each telescopic rod 310 is hinged to the bottom surface of the support assembly 400.

[0071] In this way, the angle of the support assembly 400 is adjustable and the angle adjustment of the support assembly 400 is relatively convenient. When the vehicle body is tilted or the ground is uneven, it is relatively easy to align the mounting holes 111 on the fifth wheel 100 supported by the support assembly 400 with the corresponding assembly holes on the vehicle body.

[0072] It can be understood that the four telescopic rods 310 distributed in a matrix are spaced apart from each other, and each telescopic rod 310 can be independently telescopic.

[0073] In a possible implementation manner, the lifting mechanism 300 is a hydraulic lifting mechanism 300 .

[0074] In this way, the lifting mechanism 300 can provide a greater supporting force, and the locomotive traction seat mounting device can stably support the traction seat 100. In addition, the hydraulic lifting mechanism 300 can also adjust the lifting and lowering of the support assembly 400 with a higher precision.

[0075] When the lifting mechanism 300 includes the telescopic rod 310 , the telescopic rod 310 may be a hydraulic telescopic rod 310 .

[0076] In a possible implementation manner, the base 200 is a plate-shaped structure.

[0077] In this way, the thickness of the base 200 is relatively thin, which is beneficial to lowering the height of the locomotive traction seat installation device and facilitating the movement of the locomotive traction seat installation device in the space below the vehicle body.

[0078] Exemplarily, the base 200 may be a rectangular plate.

[0079] In a possible implementation, the vertical projection of the support assembly 400 is located inside the base 200 , and the area of ​​the vertical projection of the support assembly 400 is smaller than the area of ​​the vertical projection of the base 200 .

[0080] In this way, it is convenient to install the wheels in the universal wheel set 500 to a position outside the vertical projection of the support assembly 400, so that the support for the support assembly 400 and the fifth wheel 100 is relatively stable.

[0081] Illustratively, the support assembly 400 is fixed at the center of the top surface of the base 200 .

[0082] In a possible implementation manner, an armrest 210 is fixedly connected to the base 200 .

[0083] In this way, it is convenient to move the locomotive traction seat installation device and the traction seat 100 supported thereon, and it is convenient to adjust the locomotive traction seat installation device and the traction seat 100 supported thereon.

[0084] In a possible implementation manner, armrests 210 are fixedly connected to both opposite ends of the base 200 in the horizontal direction.

[0085] In this way, it is convenient to fine-tune the position of the locomotive traction seat installation device and the traction seat 100 supported thereon, so that it is easier to align the mounting holes 111 on the traction seat 100 with the corresponding assembly holes on the vehicle body.

[0086] For example, four handrails 210 arranged in a matrix are fixedly connected to the base 200. This facilitates fine adjustment of the position of the locomotive traction seat mounting device and the traction seat 100 supported thereon, making it easy to align the mounting holes 111 on the traction seat 100 with the corresponding assembly holes on the vehicle body.

[0087] In a possible implementation, the universal wheel set 500 includes a first row of wheels and a second row of wheels arranged side by side, and the first row of wheels and the second row of wheels are arranged at intervals. The first row of wheels includes two universal wheels 510 arranged at intervals, and the second row of wheels includes two fixed wheels 520 arranged at intervals. The fixed wheels 520 are provided with a wheel locking mechanism, which is used to limit the rotation of the fixed wheel 520 and release the restriction on the rotation of the fixed wheel 520.

[0088] In this way, when the lifting mechanism 300 is raised or lowered and the traction seat 100 is installed, the directional wheel 520 can be locked by the wheel locking mechanism. After the directional wheel 520 is locked, the movement of the locomotive traction seat installation device can be restricted, thereby reducing the safety risks caused by the random movement of the locomotive traction seat installation device.

[0089] In a possible implementation manner, a top surface of the support assembly 400 is provided with an anti-skid structure, and the anti-skid structure is used to contact the vehicle body mounting plate 110 .

[0090] In this way, the movement of the traction seat 100 when it is raised is reduced, the support assembly 400 supports the traction seat 100 more stably, the traction seat 100 supported by the support assembly 400 is not easy to fall off the support assembly 400, and it is safer to lift and move the traction seat 100 through the locomotive traction seat installation device.

[0091] Exemplarily, the anti-skid structure may be an anti-skid pattern or an anti-skid rubber pad provided on the top surface of the support assembly 400 .

[0092] When the support assembly 400 includes the first support member 420 and the second support member 430, the top surfaces of the first support member 420 and the second support member 430 may be provided with anti-slip structures. Specifically, the top surfaces of the first support plate 422 and the second support plate 432 may be provided with anti-slip structures.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
