[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0032] Combination Figure 1-4 As shown, the embodiment of the present disclosure provides an auxiliary assembly device for a wet brake parking piston of an off-road mining vehicle, including: a power assembly 100 and a press-fitting part 200. The power assembly 100 has an output end 110, and the output end 110 can rotate in the horizontal direction; the press-fitting part 200 is arranged above the output end 110, one end of the press-fitting part 200 is connected to the output end 110, and the other end extends to one side of the power assembly 100 in the horizontal direction; wherein, the output end 110 of the power assembly 100 can drive the press-fitting part 200 to move in the vertical direction, and the wet brake parking piston is press-fitted by using the press-fitting part 200 extending to the other end of the power assembly 100.

[0033] The off-road mining vehicle wet brake parking piston auxiliary assembly device provided by the embodiment of the present disclosure is used. When the parking piston is assembled by the off-road mining vehicle wet brake parking piston auxiliary assembly device, the brake housing is placed on a workbench, and multiple off-road mining vehicle wet brake parking piston auxiliary assembly devices are assembled on the circumference of the brake housing, and multiple power assemblies 100 are fixed to the workbench. The parking piston with a sealing assembly installed on the outside is docked with the brake housing, and multiple press-fit parts 200 are used to press against different positions of the parking piston respectively. Each press-fit part 200 provides pressure through its corresponding power assembly 100, so that the multiple press-fit parts 200 rotate and press down the parking piston at the same time, and then the parking piston is automatically pressed into the brake housing. The intensity of the parking piston assembly work is reduced, the assembly efficiency is improved, the production efficiency is improved, and the production cost is reduced.

[0034] It can be understood that by using multiple off-road mining truck wet brake parking piston auxiliary assembly devices to press the parking piston around the brake housing, the parking piston is evenly stressed during the process of pressing it into the brake housing, reducing the risk of parking piston deviation.

[0035] Optionally, the press-fitting part 200 is made of chromium-molybdenum-vanadium alloy tool steel material. In this way, the press-fitting part 200 made of chromium-molybdenum-vanadium alloy tool steel has higher hardness and higher strength, reducing the risk of fracture and deformation of the press-fitting part 200 during press-fitting of the parking piston.

[0036] In one embodiment, the press-fitting part 200 includes: a press plate 210. The press plate 210 is a long plate-shaped structure, one end of which is connected to the output end 110, and the other end extends horizontally to one side of the power assembly 100. In this way, the press plate 210 is driven to rotate at the output end 110 of the power assembly 100, and the press plate 210 rotates to abut against the parking piston, and the parking piston is automatically pressed into the brake housing under the drive of the power assembly 100, thereby reducing the intensity of the assembly work, improving the assembly efficiency, thereby improving the production efficiency, and reducing the production cost.

[0037] Combination Figure 2As shown, in another embodiment, the press-fitting part 200 includes: a first telescopic plate 220 and a second telescopic plate 230. One end of the first telescopic plate 220 is connected to the output end 110; the second telescopic plate 230 is telescopically connected to the first telescopic plate 220, and the lower side surfaces of the first telescopic plate 220 and the second telescopic plate 230 are located in the same horizontal plane. In this way, the first telescopic plate 220 and the second telescopic plate 230 are driven to rotate at the output end 110 of the power assembly 100. For a parking piston with a relatively small size, the brake housing and the parking piston are relatively far away from the power assembly 100 on the workbench. The second telescopic plate 230 is slid out from the first telescopic plate 220, so that the second telescopic plate 230 can be smoothly rotated to abut against the parking piston, and the parking piston is automatically pressed into the brake housing under the drive of the power assembly 100. For a relatively large parking piston, the brake housing and the parking piston are relatively close to the power assembly 100 on the workbench, and the second telescopic plate 230 and the first telescopic plate 220 can be smoothly rotated to abut against the parking piston without sliding the second telescopic plate 230 from the first telescopic plate 220, and the parking piston is automatically pressed into the brake housing under the drive of the power assembly 100, thereby reducing the intensity of assembly work, improving assembly efficiency, thereby improving production efficiency and reducing production costs. Through the telescopic connection of the first telescopic plate 220 and the second telescopic plate 230, the press-fitting of parking pistons of different sizes is adapted, and the application range of the auxiliary assembly device for the parking piston of the wet brake of the off-road mining vehicle is improved.

[0038] Specifically, the inner side wall of the first telescopic plate 220 is slidably connected to the outer side wall of the second telescopic plate 230. In this way, for a relatively small parking piston, the brake housing and the parking piston are relatively far from the power assembly 100 on the workbench, and the second telescopic plate 230 is slid and extended along the inner side wall of the first telescopic plate 220, so that the second telescopic plate 230 can be smoothly rotated to abut against the parking piston, and the parking piston is automatically pressed into the brake housing under the drive of the power assembly 100, thereby adapting to the press-fitting of parking pistons of different sizes, and improving the application range of the auxiliary assembly device for the parking piston of the wet brake of the off-road mining vehicle.

[0039] Optionally, a locking knob 240 is provided at one end of the first telescopic plate 220 facing away from the output end 110, and the locking knob 240 is connected to the first telescopic plate 220 by threads, and one end of the locking knob 240 can be extended into the inner side of the first telescopic plate 220 and abut against the second telescopic plate 230. In this way, when the second telescopic plate 230 slides out from the first telescopic plate 220, the locking knob 240 is rotated on the first telescopic plate 220, and the locking knob 240 is tightly locked with the second telescopic plate 230, so as to limit the sliding of the second telescopic plate 230 and reduce the risk of the second telescopic plate 230 falling off from the first telescopic plate 220 during the process of press-fitting the parking piston.

[0040] Optionally, the power assembly 100 is a hydraulic power cylinder 120. The output end 110 of the power assembly 100 is the output shaft of the hydraulic power cylinder 120, and the output shaft can be extended and retracted in the vertical direction, and one end of the pressing plate 210 is fixedly connected to the upper end of the output shaft. In this way, the hydraulic power cylinder 120 provides power for the pressing plate 210 to press the parking piston, and the output shaft of the hydraulic power cylinder 120 is extended and retracted in the vertical direction to drive the pressing plate 210 to move, and the pressing plate 210 is driven to automatically press the parking piston into the brake housing, thereby reducing the intensity of the assembly work, improving the assembly efficiency, thereby improving the production efficiency, and reducing the production cost.

[0041] Optionally, one end of the pressing plate 210 is fixedly connected to the upper end of the output shaft via a self-locking nut 130. In this way, the output shaft of the hydraulic power cylinder 120 is connected to one end of the pressing plate 210 via the self-locking nut 130, reducing the risk of the pressing plate 210 falling off the output shaft of the hydraulic power cylinder 120 due to loosening of the nut.

[0042] It is understandable that the hydraulic cylinder 120 may also be replaced by an electric push rod.

[0043] Optionally, the off-road mining vehicle wet brake parking piston auxiliary assembly device further includes: a base 300. The base 300 is fixedly connected to the bottom of the power assembly 100. In this way, the base 300 provides support for the power assembly 100, and at the same time increases the starting height of the power assembly 100 for press-fitting the parking piston, thereby increasing the application scope of the off-road mining vehicle wet brake parking piston auxiliary assembly device. In addition, the power assembly 100 is connected to the workbench through the base 300, which makes disassembly and assembly more convenient and the connection stability is better.

[0044] It is understandable that when the parking piston press-fitting height is higher than the maximum height of the power assembly 100 extending upward, the parking piston cannot be press-fitted; when the parking piston press-fitting height is lower, a pad can be placed on the lower side of the brake housing to facilitate press-fitting of the parking piston.

[0045] Optionally, the base 300 includes: a connecting substrate 310 and a supporting platform 320. The connecting substrate 310 is a rectangular plate-shaped structure; the supporting platform 320 is fixedly connected to the upper side of the connecting substrate 310. In this way, the connecting substrate 310 is a rectangular plate-shaped structure, which can better fit the surface of the workbench and improve the stability of the connecting substrate 310 installed on the workbench.

[0046] Optionally, a plurality of connection holes 311 are provided on the connection base plate 310. In this way, the connection base plate 310 is fixed on the workbench by passing a plurality of bolts through the connection holes 311, thereby improving the stability of the connection base plate 310 installed on the workbench.

[0047] Optionally, a laser sensor 400 is provided on the base 300, and the irradiation end of the laser sensor 400 is vertically upward, for sensing the movement of the press-fitting part 200. In this way, after the press-fitting part 200 rotates and abuts against the parking piston, the press-fitting part 200 is located above the irradiation end, and the laser sensor 400 further senses the movement signal of the press-fitting part 200, detects the height of the press-fitting part 200 at the beginning of the press-fitting and the length of the press-fitting, and provides data support for the power assembly 100 to prevent the press-fitting part 200 from over-pressing the parking piston.

[0048] Optionally, the base 300 and the laser sensor 400 are connected via a connecting bracket 410. Thus, the distance between the laser sensor and the base 300 can be increased by connecting the bracket 410, thereby reducing the risk of interference caused by the base 300 to the laser sensor 400 during operation.

[0049] Combination Figure 3 As shown, optionally, the connecting bracket 410 includes: a mounting plate 411, a connecting plate 412 and a connecting seat 413. The connecting seat 413 is fixedly connected to the base 300, the connecting plate 412 and the connecting seat 413 are connected by bolts, and the connecting seat 413 and the connecting plate 412 are both arranged vertically; the mounting plate 411 is arranged horizontally, one end of which is fixedly connected to the upper end of the connecting plate 412, and the other end of the mounting plate 411 is provided with a mounting hole 414, and the mounting hole 414 is used to install the laser sensor 400. In this way, the bolts on the connecting plate 412 and the connecting seat 413 are removed, and then the connecting plate 412 and the connecting seat 413 are separated, and then the laser sensor 400 is removed, which is convenient for maintenance and replacement of the laser sensor 400. The distance between the laser sensor and the base 300 can also be increased by the mounting plate 411, the connecting plate 412 and the connecting seat 413, reducing the risk of interference caused by the base 300 when the laser sensor 400 works.

[0050] Specifically, the connecting seat 413 is fixedly connected to the supporting platform 320 .
