[0001] This application relates to the field of installation of coupler tongue bushings, and particularly to an auxiliary tool for installing coupler tongue bushings. Background Art

[0002] During the overhaul or assembly of railway freight cars, the installation of coupler tongue bushings is a key step. Traditional installation methods mainly rely on manual operations by workers, which are not only inefficient, but also difficult to ensure installation accuracy, increasing the risk of rework.

[0003] Currently, the commonly used solution is for workers to use simple tools such as hammers and pliers to apply force to the bushing for the installation of the bushing and the coupler tongue. This method requires high skills from workers, and long-term operation is likely to cause fatigue, thereby affecting the installation quality. Utility Model Content

[0004] To improve the above problems, this application provides an auxiliary tool for installing coupler tongue bushings.

[0005] An auxiliary tool for installing coupler tongue bushings provided by this application adopts the following technical solution:

[0006] An auxiliary tool for installing coupler tongue bushings includes a mobile cart. A pressing column and a press are provided on the mobile cart. An embedding groove is opened at one end of the pressing column. One end of the pressing column is embedded in the bushing. A pressing head is slidably connected to the press. A control component for controlling the sliding of the pressing head is provided on the mobile cart. The pressing head is used to apply a force to the pressing column.

[0007] By adopting the above technical solution, when the installation of the bushing and the coupler tongue is required, the operator moves the bushing to a suitable position of the coupler tongue, and then embeds one end of the pressing column into the bushing. At this time, the bottom of the embedding groove abuts against one end of the bushing. Then, the press is moved. The movement of the press can drive the movement of the pressing head, so that the pressing head abuts against the end of the pressing column away from the bushing. The control component is used to control the sliding of the pressing head. The pressing head applies a force to the pressing column, and the pressing column applies a force to the bushing, thereby installing the bushing into the coupler tongue. There is no need for manual installation with tools, reducing the labor intensity and improving the installation quality of the bushing.

[0008] Preferably, the control component includes a hydraulic pump and a connecting pipe. The hydraulic pump is installed in the mobile cart. One end of the connecting pipe is connected to the hydraulic pump, and the other end is connected to the press.

[0009] By adopting the above technical solution, when it is necessary to control the sliding of the pressing head, the operator can drive the hydraulic pump, so that the liquid in the hydraulic pump flows into the connecting pipe and then into the press through the connecting pipe, thereby pushing out the pressing head, facilitating the pressing head to exert a force on the pressing column, and further facilitating the pressing column to exert a force on the bushing.

[0010] Preferably, a handle is installed on the moving cart.

[0011] By adopting the above technical solution, the operator can move the moving cart through the handle, which is convenient for the installation of the bushing and the hook tongue.

[0012] Preferably, a hook is installed on the handle.

[0013] By adopting the above technical solution, when the pressing head is not needed, the hook can limit the connecting pipe, saving the occupied space of the connecting pipe; when the hydraulic pump is not needed, the hook can limit the wire of the hydraulic pump, saving the occupied space of the wire of the hydraulic pump.

[0014] Preferably, a placement box is provided inside the moving cart, and the placement box is for placing the pressing column.

[0015] By adopting the above technical solution, the placement box can protect the pressing column, reducing the possibility of damage to the pressing column due to collision when the moving cart moves, and facilitating the storage of the pressing column.

[0016] Preferably, a placement hole is formed in the placement box, and one end of the pressing column passes through the placement hole.

[0017] By adopting the above technical solution, when the pressing column is placed in the placement box, one end of the pressing column passes through the placement hole, and the placement hole can limit the pressing column, positioning the pressing column in the placement box and reducing the possibility of collision of the pressing column in the placement box, facilitating the storage of the pressing column.

[0018] Preferably, a limiting block is fixedly connected inside the moving cart, and a limiting groove is formed in the limiting block for placing the press.

[0019] By adopting the above technical solution, when the press is not needed, the operator can place the press in the limiting groove, and the limiting groove can limit the press, positioning the press inside the moving cart and reducing the possibility of damage caused by the collision between the press and the inner wall of the placement box when the moving cart moves, prolonging the service life of the press.

[0020] Preferably, a rubber plate is fixedly connected to the groove wall of the limiting groove, and the rubber plate is in contact with the press.

[0021] By adopting the above technical solution, the rubber plate can protect the press-fitting device, reduce the possibility of wear of the press-fitting device caused by friction between the press-fitting device and the groove wall of the limiting groove, and facilitate the storage of the press-fitting device.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the settings of the press-fitting column, press-fitting device, press-fitting head and control component, when the installation of the bushing and the hook tongue is required, the operator moves the bushing to a suitable position of the hook tongue, and then inserts one end of the press-fitting column into the bushing. At this time, the bottom of the embedding groove abuts against one end of the bushing. Then, the press-fitting device is moved. The movement of the press-fitting device can drive the movement of the press-fitting head, so that the press-fitting head abuts against the end of the press-fitting column away from the bushing. By controlling the control component to make the press-fitting head slide, the press-fitting head applies a force to the press-fitting column, and the press-fitting column applies a force to the bushing, thereby installing the bushing into the hook tongue. There is no need for manual installation with tools, reducing the labor intensity and improving the installation quality of the bushing;

[0024] 2. Through the setting of the placement hole, when the press-fitting column is placed in the placement box, one end of the press-fitting column is passed through the placement hole. The placement hole can limit the press-fitting column, position the press-fitting column in the placement box, and reduce the possibility of the press-fitting column colliding with the inner wall of the placement box.

[0031] Embodiment 1:

[0032] An auxiliary tool for installing a coupler tongue bushing is disclosed in an embodiment of the present application. As Figure 1 and 2 shown, it includes a mobile cart 1. Universal wheels are installed below the mobile cart 1, and a handle 5 is fixedly connected to the mobile cart 1. A pressing column 2 is provided inside the mobile cart 1, and an embedding groove 21 is opened at one end of the pressing column 2. An operator can move the mobile cart 1 through the handle 5. The movement of the mobile cart 1 can drive the pressing column 2 to move near the coupler tongue. Then, the operator embeds one end of the pressing column 2 into the bushing, and the bottom of the embedding groove 21 abuts against the end of the bushing away from the coupler tongue, facilitating the installation of the bushing and the coupler tongue.

[0033] As Figure 1 shown, a presser 3 is provided inside the mobile cart 1. A pressing head 31 is slidably connected to the presser 3. The pressing head 31 is used to apply a force to the pressing column 2. A control assembly 4 for controlling the sliding of the pressing head 31 is provided on the mobile cart 1. The control assembly 4 includes a hydraulic pump 41 and a connecting pipe 42. The hydraulic pump 41 is fixedly installed inside the mobile cart 1. One end of the connecting pipe 42 is connected to the hydraulic pump 41, and the other end is connected to the presser 3. After one end of the pressing column 2 is embedded into the bushing, the operator moves the presser 3 to a suitable position. The movement of the presser 3 can drive the movement of the pressing head 31, so that the pressing head 31 moves to abut against the end of the pressing column 2 away from the bushing. Then, the hydraulic pump 41 is driven. The hydraulic pump 41 can apply a force to the pressing head 31 through the connecting pipe 42, causing the pressing head 31 to move away from the presser 3. The pressing head 31 can apply a force to the pressing column 2, and the pressing column 2 can apply a force to the bushing, causing the bushing to be embedded into the coupler tongue, thereby realizing the installation of the bushing and the coupler tongue.

[0034] As Figure 1 shown, a hook 51 is fixedly connected to the handle 5. When the pressing head 31 is not needed, the hook 51 can limit the connecting pipe 42, saving the occupied space of the connecting pipe 42; when the hydraulic pump 41 is not needed, the hook 51 can limit the wire of the hydraulic pump 41, saving the occupied space of the wire of the hydraulic pump 41.

[0035] The implementation principle of an auxiliary tool for installing a coupler knuckle bushing in an embodiment of the present application is as follows:

[0036] When the bushing needs to be installed, the operator inserts one end of the pressing column 2 into the bushing, and the bottom of the insertion groove 21 abuts against one end of the bushing. Then, the pressing device 3 is moved so that the pressing head 31 abuts against the end of the pressing column 2 away from the bushing. The hydraulic pump 41 is driven, and the hydraulic pump 41 controls the pressing head 31 to move away from the pressing device 3. The pressing head 31 exerts a force on the pressing column 2, and the pressing column 2 exerts a force on the bushing, causing the bushing to be inserted into the coupler knuckle, thereby realizing the installation of the bushing and the coupler knuckle.

When the pressing column 2 is not needed, the operator can place the pressing column 2 in the placement box 6 for storage. When the pressing column 2 is placed in the placement box 6, the operator puts one end of the pressing column 2 into the placement hole 61. The placement hole 61 can limit the pressing column 2, so that the pressing column 2 is positioned inside the placement box 6, reducing the possibility of collision of the pressing column 2 inside the placement box 6 and facilitating the storage of the pressing column 2.

[0039] As Figure 3 shown, a limiting block 7 is fixedly connected inside the moving vehicle 1, and a limiting groove 71 is provided on the limiting block 7, and a limiting groove 71 is provided on the limiting block 7. A rubber plate 72 is fixedly connected to the wall of the limiting groove 71, and the rubber plate 72 is attached to the pressing device 3. When the pressing device 3 is not needed, the operator can put the pressing device 3 into the limiting groove 71. The limiting groove 71 can limit the pressing device 3, so that the pressing device 3 is limited inside the moving vehicle 1, reducing the possibility of damage caused by collision of the pressing device 3 inside the moving vehicle 1 and facilitating the storage of the pressing device 3; the rubber plate 72 can further protect the pressing device 3, reducing the possibility of friction between the outer wall of the pressing device 3 and the wall of the limiting groove 71, resulting in wear of the pressing device 3, and extending the service life of the pressing device 3.

[0040] The implementation principle of an auxiliary tool for installing a coupler knuckle bushing in an embodiment of the present application is as follows:

[0041] The operator can place the press-fitting column 2 in the placement box 6 for storage, and the placement hole 61 can limit the press-fitting column 2, reducing the possibility of damage to the press-fitting column 2 due to collision and facilitating the storage of the press-fitting column 2; the operator can place the press-fitting device 3 in the limiting groove 71 for storage, the limiting groove 71 can limit the press-fitting device 3, and the rubber plate 72 can reduce the possibility of wear of the press-fitting device 3, facilitating the storage of the press-fitting device 3.
