Abstract
Description
Technical Field

[0002] Steering gears are usually made of materials that are not easily rusted and are strong to ensure the safety and reliability of automobiles. The steering gear of a loader is hydraulically controlled and has a precise internal structure. When maintenance personnel perform internal maintenance, they need to remove the valve body to replace the internal seal. When performing this process, the positioning spring inside the steering gear needs to be contracted to be successfully removed. If the internal spring is not contracted, the disassembly and assembly process will be greatly increased in difficulty, and there is a high probability of causing wear to the steering gear control valve, resulting in steering jamming and abnormal noise in the steering gear, making the disassembly work take a long time and affecting the maintenance efficiency. Content of the Utility Model

One side of the connecting block is provided with a grip for holding, and a long rod is arranged between the connecting block and the six-flower head.
[0005] Preferably, the upper end of the grip is fixedly connected with a long rod, and the grip is connected with the six-flower head through the long rod.
[0006] Preferably, the surface of the grip is provided with anti-slip lines.
[0007] Preferably, the surface of the long rod is provided with anti-slip lines.
[0008] Preferably, the grip is connected with the six-flower head through the long rod.
[0009] Preferably, the materials of the connecting block, the grip, the six-flower head and the long rod are stainless steel.
[0010] The separating device for a steering gear spool and a housing of the utility model has the following advantages:
[0011] For the separating device for a steering gear spool and a housing, through the settings of the connecting block, the grip and the six-flower head, when disassembling the steering gear spool, hold the grip, insert the six-flower head into the spline sleeve of the steering gear spool transmission, and rotate the socket wrench to contract the fixed spring of the spool so that it is separated from the housing, shortening the time for disassembling the steering gear spool.

[0023] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a separating device for a steering gear spool and a housing of the present utility model with reference to the accompanying drawings.
[0024] As Figure 1 shown, a separating device for a steering gear spool and a housing of the present utility model includes a spline sleeve arranged at the transmission part of the steering control valve of the steering gear, and further includes a connecting block 1 and a six-flower head 2 matching with the spline sleeve of the spool transmission. One side of the connecting block 1 is provided with a handle 11 for holding, and a long rod 21 is arranged between the connecting block 1 and the six-flower head 2.
[0025] As Figures 2 - 3 shown, the upper end of the handle 11 is fixedly connected with the long rod 21. The diameter of the long rod 21 is smaller than the diameter of the six-flower head 2. The handle 11 is connected with the six-flower head 2 through the long rod 21, and the six-flower head 2 is a hexagonal rectangular block.
[0026] As Figure 4 shown, the surfaces of the handle 11 and the long rod 21 are provided with anti-slip lines to prevent slipping when using the device.
[0027] As Figure 2 shown, the distance between one end of the connecting block 1 away from the handle 11 and one end of the handle 11 away from the connecting block 1 is 7-9 cm.
[0028] As Figure 3 shown, the distance between one end of the connecting block 1 away from the six-flower head 2 and one end of the six-flower head 2 away from the connecting block 1 is 20 cm.
[0029] AsFigure 3 As shown, the diameter of the six - petal head 2 is 1.82 cm.
[0030] As Figure 4 As shown, the connecting block 1, the grip 11, the six - petal head 2 and the long rod 21 are made of stainless steel material to prevent the device from rusting and affecting its service life.
[0031] In summary: When disassembling the steering gear steering control valve from the housing, remove the valve end cover of the steering gear. Hold the grip 11 by hand, and make the six - petal head 2 engage with the transmission spline sleeve of the steering gear valve core. The transmission spline sleeve at the transmission part of the steering gear valve core is a hexagonal rectangular groove. Insert the six - petal head 2 into the transmission spline sleeve of the steering gear valve core and rotate the socket wrench to make the valve core fixing spring contract, so that it is separated from the housing. The disassembly operation time: It can be completed in 2 minutes, shortened from the original 10 minutes. This reduces the probability of personal injury accidents during the forced separation of the valve core and the housing, improves the safety during maintenance operations, and reduces the wear of the steering gear control valve.
[0032] It can be understood that the present utility model is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
