[0047] Figure 1 A schematic diagram of a side bearing is shown in FIG. Figure 2The present invention is a cross-sectional schematic diagram of a side bearing installed on a vehicle body within a side bearing installation tube.

[0048] like Figure 1 , Figure 2 As shown, a locomotive is commonly known as a locomotive, and is used to pull or push a railway vehicle. The locomotive may include a car body 200 and a bogie. In some locomotives, a ball head seat may be provided on the bogie, and a side bearing mounting cylinder 210 is provided on the car body 200. The ball head 110 at the lower part of the side bearing 100 is mounted on the ball head seat of the bogie, and the upper part of the side bearing 100 is sleeved in the side bearing mounting cylinder 210. The top end of the side bearing 100 may be fixed to the pressure plate 220 on the car body 200 by a first fastener 230, so that the car body 200 can be mounted on the bogie through the side bearing 100.

[0049] Specifically, the side bearing 100 may include a ball head 110, a center shaft 130 and an elastic sleeve assembly 120. The ball head 110 is coaxially arranged with the center shaft 130. The ball head 110 is fixedly connected to the lower end of the center shaft 130. The ball head 110 and the center shaft 130 may be an integral structure. The elastic sleeve assembly 120 is sleeved on the outside of the center shaft 130. The elastic sleeve assembly 120 is located above the ball head 110. The upper end of the ball head 110 supports the elastic sleeve assembly 120. The upper end of the center shaft 130 passes through the elastic sleeve assembly 120. A first assembly hole 131 is provided at the center of the upper end surface of the center shaft 130. The first assembly hole 131 may be a threaded hole. The elastic sleeve assembly 120 may be formed by alternatingly stacking elastic gaskets 121 and rigid gaskets 122. The inner cavity of the side bearing mounting cylinder 210 passes through the lower surface of the car body 200, and a second assembly hole 211 for accommodating the upper end of the central axis 130 is provided at the center of the top wall of the side bearing mounting cylinder 210. The second assembly hole 211 is a through hole. After the elastic sleeve assembly 120 of the side bearing 100 is sleeved in the side bearing mounting cylinder 210, a pressure plate 220 with a third assembly hole 221 can be placed on the upper surface of the top wall of the side bearing mounting cylinder 210. The third assembly hole 221 is a through hole. The side bearing 100 can be fixed to the side bearing mounting cylinder 210 by a first fastener 230 penetrated through the third assembly hole 221 and the first assembly hole 131. The pressure plate 220 is supported by the top wall of the side bearing mounting cylinder 210, and the ball head 110 of the side bearing 100 is exposed below the side bearing mounting cylinder 210. The ball head 110 of the side bearing 100 is used to be connected to the ball head seat of the bogie. The lower surface of the vehicle body 200 may also be provided with a side bearing cover clamping edge 240 for mounting the side bearing cover, and the opening of the side bearing mounting tube 210 on the lower surface of the vehicle body 200 is located in the side bearing cover clamping edge 240 .

[0050] In the related art, when installing the side bearing on the vehicle body, the upper part of the side bearing is often inserted into the side bearing installation tube on the vehicle body by manual lifting. After the upper part of the side bearing is inserted into the side bearing installation tube, another operator fixes the top end of the side bearing to the side bearing installation tube.

[0051] In the related art, it takes a large number of operators to install the side bearing into the side bearing installation tube, and the labor intensity of the operators is relatively high. In addition, when lifting the side bearing, it is necessary to apply force to the spherical surface of the ball head, and there is often grease on the spherical surface of the ball head. Manual force applied to the spherical surface of the ball head is prone to slipping, and the side bearing lifted manually is prone to falling, which can easily cause personal injury, device damage and other problems, and poses a great safety hazard. In addition, during the installation of the side bearing, it is difficult to keep the side bearing aligned with the side bearing installation tube, and the side bearing is prone to getting stuck when moving in the side bearing installation tube.

[0052] Figure 3 A schematic diagram of a locomotive side bearing installation device provided in an embodiment of the present application, Figure 4 A schematic diagram of a locomotive side bearing installation device supporting a side bearing provided by an embodiment of the present application, Figure 5 A schematic diagram of a locomotive side bearing installation device provided in an embodiment of the present application supporting a side bearing below a side bearing installation cylinder.

[0053] like Figure 3-Figure 5 As shown, and see Figure 1 , Figure 2 Based on this, the embodiment of the present application provides a locomotive side bearing installation device, which includes a base plate 300, a lifting mechanism 400, a carrier plate 500, a ball head support seat 510, a guide mechanism 900, a straightening assembly 700 and an elastic support mechanism 800. The carrier plate 500 is installed above the base plate 300 through the lifting mechanism 400, and the ball head support seat 510 is fixedly installed on the upper surface of the carrier plate 500. The upper end of the guide mechanism 900 is fixedly connected to the lower surface of the straightening assembly 700, and the straightening assembly 700 is slidably connected to the carrier plate 500 through the guide mechanism 900. The straightening assembly 700 is arranged above the carrier plate 500, and the straightening assembly 700 and the guide mechanism 900 can slide up and down relative to the carrier plate 500. The elastic support mechanism 800 is arranged between the straightening assembly 700 and the carrier plate 500, and the upper end of the elastic support mechanism 800 abuts against the straightening assembly 700, and the lower end of the elastic support mechanism 800 abuts against the carrier plate 500. The straightening assembly 700 defines a side bearing mounting opening for passing the side bearing 100, and the ball head support seat 510 is arranged directly below the side bearing mounting opening. Among them, the ball head support seat 510 is used to support the ball head 110 of the side bearing 100, the inner wall of the straightening assembly 700 is used to contact the surrounding wall of the elastic sleeve assembly 120 of the side bearing 100 supported by the ball head support seat 510 to limit the swing of the side bearing 100 supported by the ball head support seat 510, and the upper surface of the straightening assembly 700 is used to contact the lower surface of the vehicle body 200.

[0054] It is understandable that the lifting mechanism 400 can be used to adjust the vertical spacing between the bottom plate 300 and the carrier plate 500. After the side bearing 100 is placed in the side bearing installation opening and the ball head 110 of the side bearing 100 is supported by the ball head support seat 510, the side bearing 100 is straightened by the straightening assembly 700. At this time, the supported side bearing 100 can be lifted by the lifting mechanism 400 so that the elastic sleeve assembly 120 of the side bearing 100 gradually enters the side bearing installation cylinder 210. When the supported side bearing 100 gradually enters the side bearing installation cylinder 210, the upper surface of the straightening assembly 700 abuts against the lower surface of the vehicle body 200, the elastic support mechanism 800 is compressed, and the straightening assembly 700 gradually moves closer to the carrier plate 500. The lifting mechanism 400 can move in the direction of the side bearing 100 so as to keep the side bearing 100 straightened without affecting the side bearing 100 entering the side bearing installation cylinder 210. After the side bearing 100 enters the preset position in the side bearing installation cylinder 210, the lifting mechanism 400 stops lifting and the operator can insert the first fastener 230 into the third assembly hole 221 of the pressure plate 220 and the first assembly hole 131 of the side bearing 100 to fix the side bearing 100 to the side bearing installation cylinder 210. After the side bearing 100 is fixed to the side bearing installation cylinder 210, the carrier plate 500 and the straightening assembly 700 can be lowered by the lifting mechanism 400.

[0055] In this way, after the side bearing 100 is placed in the side bearing installation opening and the ball head 110 of the side bearing 100 is supported by the ball head support seat 510, only one operator is needed to complete the installation of the side bearing 100 in the side bearing installation cylinder 210, and the number of operators required is relatively small. In addition, the side bearing 100 is supported by the locomotive side bearing installation device and can be lifted by the locomotive side bearing installation device to enter the side bearing installation cylinder 210, which can reduce the work intensity of the operator. In addition, from the time when the side bearing 100 is placed on the ball head support seat 510 to the time when the side bearing 100 is installed with the side bearing installation cylinder 210, the straightening assembly 700 can prevent the side bearing 100 supported by the ball head support seat 510 from falling, and the safety of installing the side bearing 100 is relatively high. Furthermore, after the side bearing 100 is placed on the ball head support seat 510 and until the installation with the side bearing mounting tube 210 is completed, the straightening assembly 700 can play the role of straightening the side bearing 100 supported by the ball head support seat 510, which is beneficial for the side bearing 100 to maintain alignment with the side bearing mounting tube 210, and the side bearing 100 is not prone to getting stuck when moving in the side bearing mounting tube 210.

[0056] It can be understood that the upper surface of the centralizing assembly 700 can be used to abut against a portion of the lower surface of the vehicle body 200 located within the side bearing cover clamping edge 240 .

[0058] like Figure 3-Figure 5 As shown, in some other possible implementations, the straightening assembly 700 includes a first fan ring plate 710 and a second fan ring plate 720, the guide mechanism 900 includes a first guide column 910 and a second guide column 920, and the elastic support mechanism 800 includes a first elastic support assembly 810 and a second elastic support assembly 820. The first fan ring plate 710 and the second fan ring plate 720 are spaced apart, and the axes of the first fan ring plate 710 and the second fan ring plate 720 coincide. The upper end of the first guide column 910 is fixedly connected to the lower surface of the first fan ring plate 710, and the first fan ring plate 710 is slidably connected to the carrier plate 500 through the first guide column 910. The upper end of the second guide column 920 is fixedly connected to the lower surface of the second fan ring plate 720, and the second fan ring plate 720 is slidably connected to the carrier plate 500 through the second guide column 920. The first fan ring plate 710 and the second fan ring plate 720 are both located above the carrier plate 500. The first fan ring plate 710 and the first guide column 910 as well as the second fan ring plate 720 and the second guide column 920 are connected to the carrier plate 500. The columns 920 can slide up and down relative to the carrier 500. The first elastic support component 810 is arranged between the first fan ring plate 710 and the carrier 500. The upper end of the first elastic support component 810 abuts against the first fan ring plate 710, and the lower end of the first elastic support component 810 abuts against the carrier 500. The second elastic support component 820 is arranged between the second fan ring plate 720 and the carrier 500. The upper end of the second elastic support component 820 abuts against the second fan ring plate 720, and the lower end of the second elastic support component 820 abuts against the carrier 500. The inner wall of the first fan ring plate 710 and the inner wall of the second fan ring plate 720 define a side bearing installation opening, and the inner wall of the first fan ring plate 710 and the inner wall of the second fan ring plate 720 are both used to abut against the peripheral wall of the elastic sleeve assembly 120 of the side bearing 100 supported by the ball head support seat 510 to limit the swing of the side bearing 100 supported by the ball head support seat 510, and the upper surface of the first fan ring plate 710 and the upper surface of the second fan ring plate 720 are both used to abut against the lower surface of the vehicle body 200.

[0059] In this way, it is convenient to first place the ball head 110 and the center shaft 130 of the side bearing 100 into the side bearing installation opening, and make the ball head 110 of the side bearing 100 supported by the ball head support seat 510, and then alternately sleeve the elastic gasket 121 and the rigid gasket 122 on the center shaft 130 to form an elastic sleeve assembly 120 on the outside of the center shaft 130. When sleeveing ​​the elastic gasket 121 and the rigid gasket 122, the operator can support the elastic gasket 121 and the rigid gasket 122 through the gap between the first fan ring plate 710 and the second fan ring plate 720, so that it is more convenient and safe to sleeve the elastic gasket 121 and the rigid gasket 122, which can reduce the difficulty of placing the side bearing 100 on the locomotive side bearing installation device.

[0060] Exemplarily, the outer diameter of the rigid gasket 122 is greater than the outer diameter of the elastic gasket 121 , and the inner wall of the first fan ring plate 710 and the inner wall of the second fan ring plate 720 are both used to abut against the peripheral wall of the rigid gasket 122 .

[0061] In some possible implementations, the first elastic support assembly 810 includes a plurality of first column springs 811 disposed at intervals, and the second elastic support assembly 820 includes a plurality of second column springs 821 disposed at intervals. A plurality of first limiting sleeves 711 corresponding to the first column springs 811 are fixedly connected to the lower surface of the first fan ring plate 710, and a plurality of second limiting sleeves 520 corresponding to the first column springs 811 are fixedly connected to the upper surface of the carrier plate 500. The upper end of the first column spring 811 is sleeved in the corresponding first limiting sleeve 711 and abuts against the lower surface of the first fan ring plate 710, and the lower end of the first column spring 811 is sleeved in the corresponding second limiting sleeve 520 and abuts against the upper surface of the carrier plate 500. The lower surface of the second fan ring plate 720 is fixedly connected with a plurality of third limit sleeves 721 corresponding one-to-one to the second column spring 821, and the upper surface of the carrier plate 500 is fixedly connected with a plurality of fourth limit sleeves 530 corresponding one-to-one to the second column spring 821. The upper end of the second column spring 821 is sleeved in the corresponding third limit sleeve 721 and abuts against the lower surface of the second fan ring plate 720, and the lower end of the second column spring 821 is sleeved in the corresponding fourth limit sleeve 530 and abuts against the upper surface of the carrier plate 500.

[0062] In this way, the first elastic support assembly 810 and the second elastic support assembly 820 can be extended and retracted to a greater extent, and the first fan ring plate 710 and the second fan ring plate 720 can move along a longer path, which is conducive to installing the side bearing 100 supported by the ball head support seat 510 to a preset position in the side bearing installation cylinder 210. In addition, both ends of the first column spring 811 are limited by the first limiting sleeve 711 and the second limiting sleeve 520, and both ends of the second column spring 821 are limited by the third limiting sleeve 721 and the fourth limiting sleeve 530, so that the first column spring 811 and the second column spring 821 are not easily displaced.

[0063] In some examples, the first column spring 811 may also be sleeved on the outside of the first guide column 910 , and the second column spring 821 may also be sleeved on the outside of the second guide column 920 .

[0064] In some possible implementations, at least two first guide posts 910 are fixedly connected to the lower surface of the first fan ring plate 710 , and at least two second guide posts 920 are fixedly connected to the lower surface of the second fan ring plate 720 .

[0065] In this way, the first fan ring plate 710 and the second fan ring plate 720 are not prone to shaking.

[0066] In some possible embodiments, a first sliding hole corresponding to the first guide column 910 is opened on the carrier plate 500, the first guide column 910 is inserted into the corresponding first sliding hole and slidably cooperates with the hole wall of the first sliding hole, and the lower end of the first guide column 910 is fixedly connected with a first limiting cap 911, and the first limiting cap 911 is arranged below the carrier plate 500. The first limiting cap 911 is used to abut against the lower surface of the carrier plate 500 to limit the maximum distance between the first fan ring plate 710 and the carrier plate 500.

[0067] In this way, the first limiting cap 911 can be used to limit the first guide column 910 from escaping from the first sliding hole, thereby reducing the risk of the first guide column 910 being separated from the carrier plate 500, and the first guide column 910 and the first fan ring plate 710 are not easily separated from the carrier plate 500.

[0068] In some possible embodiments, a second sliding hole corresponding to the second guide column 920 is opened on the carrier 500, the second guide column 920 is inserted into the corresponding second sliding hole and slidably cooperates with the hole wall of the second sliding hole, and the lower end of the second guide column 920 is fixedly connected to a second limiting cap 921, the second limiting cap 921 is arranged below the carrier 500, and the second limiting cap 921 is used to abut against the lower surface of the carrier 500 to limit the maximum distance between the second fan ring plate 720 and the carrier 500.

[0069] In this way, the second limiting cap 921 can be used to limit the second guide column 920 from escaping from the second sliding hole, thereby reducing the risk of the second guide column 920 separating from the carrier plate 500, and the second guide column 920 and the second fan ring plate 720 are not easily separated from the carrier plate 500.

[0070] In an embodiment in which at least two first guide pillars 910 are fixedly connected to the lower surface of the first fan ring plate 710 and at least two second guide pillars 920 are fixedly connected to the lower surface of the second fan ring plate 720, at least two first sliding holes corresponding one-to-one to the first guide pillars 910 are opened on the carrier plate 500, and at least two second sliding holes corresponding one-to-one to the second guide pillars 920 are opened on the carrier plate 500.

[0071] In some examples, the lifting mechanism 400 includes a telescopic rod 410 , the lower end of the telescopic rod 410 is fixedly connected to the upper surface of the base plate 300 , and the upper end of the telescopic rod 410 is fixedly connected to the lower surface of the carrier plate 500 .

[0072] In a possible embodiment, the lifting mechanism 400 includes three telescopic rods 410 distributed in a triangle on the upper surface of the base plate 300, the lower ends of the telescopic rods 410 are fixedly connected to the upper surface of the base plate 300, and the upper ends of the telescopic rods 410 are hinged to the lower surface of the carrier plate 500.

[0073] In this way, the angle of the carrier plate 500 and the ball head support seat 510 installed thereon is adjustable, so that the angle of the side bearing 100 supported by the ball head support seat 510 can be adjusted. The angle of the carrier plate 500 and the ball head support seat 510 installed thereon can be adjusted according to the actual state of the vehicle body 200 and the flatness of the ground, which helps to eliminate the problem of difficulty in aligning the side bearing 100 supported by the ball head support seat 510 with the side bearing mounting tube 210 on the vehicle body 200 due to the tilt of the vehicle body 200 or the uneven ground, thereby facilitating the installation of the side bearing 100 and the vehicle body 200.

[0074] It can be understood that the three telescopic rods 410 distributed in a triangle are spaced apart from each other, and each telescopic rod 410 can be independently telescopic.

[0075] In some possible embodiments, the lifting mechanism 400 includes four telescopic rods 410 distributed in a matrix on the upper surface of the base plate 300, the lower ends of the telescopic rods 410 are fixedly connected to the upper surface of the base plate 300, and the upper ends of the telescopic rods 410 are hinged to the lower surface of the carrier plate 500.

[0076] In this way, the angle of the carrier plate 500 and the ball head support seat 510 installed thereon is adjustable, and it is relatively convenient to adjust the angle of the carrier plate 500 and the ball head support seat 510 installed thereon. When the vehicle body 200 is tilted or the ground is uneven, it is relatively easy to align the side bearing 100 supported by the ball head support seat 510 with the side bearing mounting tube 210 on the vehicle body 200.

[0077] It can be understood that the four telescopic rods 410 distributed in a matrix are spaced apart from each other, and each telescopic rod 410 can be independently telescopic.

[0078] It is understandable that the upper end of the telescopic rod 410 can be hinged to the lower surface of the carrier plate 500 via a hinge seat.

[0079] In a possible implementation manner, the lifting mechanism 400 is a hydraulic lifting mechanism.

[0080] In this way, the lifting mechanism 400 can provide a greater supporting force, and the locomotive side bearing installation device can stably support the side bearing 100. In addition, the hydraulic lifting mechanism can also adjust the lifting and lowering of the carrier plate 500 with a higher precision.

[0081] When the lifting mechanism 400 includes the telescopic rod 410 , the telescopic rod 410 may be a hydraulic telescopic rod.

[0082] In some possible implementations, the ball head support seat 510 is detachably connected to the carrier plate 500 .

[0083] In this way, the ball head support seat 510 can be replaced, which makes it easy to replace the ball head 110 support column according to the side bearing 100 that needs to be supported, so that the locomotive side bearing installation device has better versatility.

[0084] Exemplarily, the ball head support seat 510 can be detachably connected to the carrier plate 500 by means of snap connection, fastener connection, etc.

[0085] Exemplarily, the ball head support seat 510 may include a seat body 511 and a mounting plate 513, the lower end of the seat body 511 is fixedly connected to the mounting plate 513, the upper end of the seat body 511 has a groove 512, and the mounting plate 513 can be detachably connected to the carrier plate 500 via a second fastener.

[0086] In some possible implementations, the upper surface of the ball head support seat 510 has a groove 512 , the inner wall of the groove 512 is a spherical structure for fitting with the surface of the ball head 110 , and the inner wall of the groove 512 is used to support the ball head 110 .

[0087] In this way, the support of the ball head 110 by the ball head support seat 510 is more stable, and when the elastic sleeve assembly 120 is not set on the central shaft 130 connected to the ball head 110 supported by the ball head support seat 510, the ball head 110 and the central shaft 130 are not easy to swing.

[0088] In some possible embodiments, a plurality of mutually spaced connection posts 310 are fixedly connected to the upper surface of the base plate 300, a plurality of connection holes corresponding to the connection posts 310 are opened on the carrier plate 500, the connection posts 310 are inserted into the corresponding connection holes, the connection posts 310 are gap-matched with the hole walls of the corresponding connection holes, a third limiting cap 311 is fixedly connected to the upper end of the connection post 310, the third limiting cap 311 is arranged above the carrier plate 500, and the third limiting cap 311 is used to abut against the upper surface of the carrier plate 500 to limit the maximum distance between the base plate 300 and the carrier plate 500.

[0089] In this way, the height to which the carrier plate 500 and the side bearing 100 supported by the ball head support seat 510 are lifted can be limited, the risk of the side bearing 100 or the straightening assembly 700 damaging the side bearing mounting tube 210 or the vehicle body 200 can be reduced, and when the lifting mechanism 400 is out of control, a safety accident caused by the carrier plate 500 being lifted too high is less likely to occur.

[0090] In some possible implementations, the locomotive side bearing mounting device further includes a universal wheel set 600 , and the universal wheel set 600 is mounted on the bottom of the base plate 300 .

[0091] In this way, the locomotive side bearing installation device is easily moved, and the position of the locomotive side bearing installation device and the side bearing 100 placed thereon is adjusted, and the side bearing 100 is easily aligned with the side bearing installation cylinder 210 .

[0092] In some possible implementations, the universal wheel set 600 includes a first row of wheels 610 and a second row of wheels 620 arranged side by side, the first row of wheels 610 and the second row of wheels 620 are arranged at intervals, the first row of wheels 610 includes two universal wheels 611 arranged at intervals, and the second row of wheels 620 includes two fixed wheels 621 arranged at intervals. The fixed wheels 621 are provided with a wheel locking mechanism, which is used to limit the rotation of the fixed wheel 621 and release the restriction on the rotation of the fixed wheel 621.

[0093] In this way, when the lifting mechanism 400 is raised or lowered and the side bearing 100 is installed, the directional wheel 621 can be locked by the wheel locking mechanism. After the directional wheel 621 is locked, the movement of the locomotive side bearing installation device can be restricted, thereby reducing the safety risks caused by the random movement of the locomotive side bearing installation device.

[0094] In some possible embodiments, the locomotive side bearing mounting device also includes a mounting frame 320, the lower end of the mounting frame 320 is fixedly connected to the base plate 300, the mounting frame 320 is arranged at the end of the base plate 300, and the upper end of the mounting frame 320 is equipped with a handrail 321, and the handrail 321 is installed on the side of the mounting frame 320 away from the base plate 300.

[0095] In this way, it is convenient to install the handrail 321 above the bottom plate 300. After the handrail 321 is arranged above the bottom plate 300, it is more convenient to push the locomotive side bearing installation device.

[0096] 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.
