[0020] The present invention will now be described in further detail.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 2 As shown, a heavy-duty mining truck battery assembly disassembly device mainly consists of five parts: an adjustment mechanism 100, a support mechanism I 200, a support mechanism II 300, a support mechanism III 400, and a power control system 500. The support mechanism I 200 and the support mechanism III 400 are horizontally slidably connected to both ends of the rear side of the adjustment mechanism 100, and the support mechanism II 300 is fixedly connected to the middle of the rear side of the adjustment mechanism 100, with the support mechanism II 300 positioned between the support mechanism I 200 and the support mechanism III 400. The lower middle part of the adjustment mechanism 100 is provided with a steering wheel 600, and the lower ends of the support mechanism I 200, support mechanism II 300 and support mechanism III 400 are all provided with steering wheels 600 and heavy-duty universal wheels 700. Support mechanism I 200 and support mechanism III 400 have the same structure. Support mechanism II 300 has a similar structure to support mechanism I 200 and support mechanism III 400. The difference is that support mechanism II 300 is equipped with only one set of support components, which are the telescopic components used for lifting. The telescopic component is driven to move horizontally via a drive assembly and a second transmission assembly on the support mechanism; like Figure 3 The adjustment mechanism 100 shown has a housing 101 on one side that drives the support mechanism to move left and right in the horizontal direction via a drive assembly and a first transmission assembly. The drive assembly includes a servo motor 102 and a planetary reducer 103. The first transmission assembly includes a bidirectional ball screw 104, a first slider 106, and a second slider 107. The servo motor 102, the planetary reducer 103, and the transmission connection method with the bidirectional ball screw 104 are existing technologies and will not be described in detail here.

[0023] The two ends of the bidirectional ball screw 104 are mounted in the support seat 109 through bearings 108, and the support seat 109 is fixed to both sides of the housing 101 by screws.

[0024] The rear side of the housing 101 is also provided with a horizontally extending guide rail 105, which, in conjunction with... Figure 4 As shown, one end of the support mechanism I 200 is provided with a mounting plate 208. The mounting plate 208 has a sliding groove that is slidably connected to the guide rail 105. The mounting plate 208 of the support mechanism I 200 is fixedly connected to the first slider 106. Figure 6 As shown, the mounting plate 208 of the support mechanism Ⅲ400 is fixedly connected to the second slider 107.

[0025] Combination Figure 4 , Figure 5 , Figure 6As shown, the structures of support mechanism II 300, support mechanism I 200, and support mechanism III 400 are roughly the same.

[0026] Combination Figure 4 As shown, support mechanism I 200 and support mechanism III 400 have the same mechanism. Support mechanism I 200 includes a bracket 201, and heavy-duty casters 700 and steering wheels 600 are installed at the lower end of the bracket 201; The bracket 201 has two bushings 207 that pass through it. The bushings 207 of the support mechanism I 200 and the support mechanism III 400 are connected in series by the guide rod of the support mechanism II 300. The guide rod is slidably connected to the bushing 207.

[0027] A parallel and horizontally extending track 203 and a second transmission assembly are fixedly connected to the bracket 201; The second transmission assembly includes a rack 202 mounted parallel to the track 203; A connecting plate 204 is slidably connected to the track 203. A support column 205 and a servo motor 102 are fixedly connected to the connecting plate 204 by bolts. A telescopic component I 206 (i.e., a lifting cylinder) is fixedly connected to the support column 205 by bolts. The output shaft of the servo motor 102 passes downward through the connecting plate 204 and is connected by a key to a gear that meshes with a rack 202. When the servo motor 102 rotates, it drives the gear to rotate. The gear meshes with the rack 202, transmitting force to the connecting plate 204 through the fixing bolts of the servo motor 102. This drives the connecting plate 204 to slide along the track 203, thereby adjusting the position of the telescopic component.

[0028] The support mechanism I200 has two sets of connecting plates 204 that are slidably connected. The two sets of connecting plates 204 are respectively equipped with telescopic component I206 and telescopic component II209.

[0029] The support mechanism Ⅱ300 is equipped with a telescopic component Ⅲ302.

[0030] The support mechanism Ⅲ400 is equipped with telescopic component Ⅳ401 and telescopic component Ⅴ402.

[0031] Combination Figure 7As shown, a hydraulic pump station 501, a power battery assembly 502, and a walking control system 503 are installed inside the housing 101. A wireless remote control component 504 is installed on the housing 101. The hydraulic pump station 501 is connected to telescopic components I 206, II 209, III 302, IV 401, and V 402 via hydraulic pipelines, and controls the lifting of multiple telescopic components through the hydraulic pump station 501. The power battery assembly 502 is electrically connected to the walking control system 503, which is electrically connected to the servo motor 102 and the steering wheel 600. The power battery assembly 502 supplies power to the walking control system 503, the servo motor 102, and the steering wheel 600. The walking control system 503 is used to control the servo motor 102 and the steering wheel 600 (this part belongs to the prior art and will not be described in detail here).

[0032] Combination Figure 1 , Figure 2 , Figure 8 As shown, the heavy-duty mining truck battery assembly disassembly equipment of this embodiment operates as follows: 1) Tow the disabled vehicle to a flat surface, release the parking brake, and disassemble the high-voltage wiring harness, cooling water circuit, low-voltage wires, and front and rear mounting shock absorbers.

[0033] 2) Control each steering wheel 600 drive device to enter the bottom of the battery assembly, and control the bidirectional ball screw 104 to drive the first slider 106 and the second slider 107 to adjust the left and right distance of the support mechanism I 200 and the support mechanism III 400 to keep it consistent with the width of the two longitudinal beams of the battery frame.

[0034] 3) Telescopic components II 209 and V 402 are driven to the rear end of the battery rack by servo motor 102, and telescopic components I 206 and IV 401 are driven to the middle position between the front beam and the gantry beam by servo motor 102. The four telescopic components simultaneously lift the longitudinal beam of the battery rack, so that the battery assembly moves upward by 100mm and is removed from the frame mounting seat. The equipment lifts the battery assembly and moves it forward by four steering wheels 600, so that the battery assembly bracket 201 extends out of the front bumper, completing the first movement.

[0035] 4) Telescopic component III 302 is driven by servo motor 102 to the frontmost bracket 201 crossbeam of the battery rack, where it extends to complete the lifting. Telescopic components I 206 and IV 401 move backward along the longitudinal beam of the battery rack via servo motor 102 until they are close to the front side of the gantry beam, and are lifted onto the longitudinal beam of the battery rack. At this time, the five hydraulic cylinders move forward via four steering wheels 600 until telescopic components II 209 and V 402 are close to the rear side of the gantry beam, completing the second movement.

[0036] 5) Telescopic components I 206 and IV 401 are depressurized and shortened, then moved to the foremost position along the battery rack longitudinal beam via servo motor 102, and lifted onto the battery rack. Telescopic component III 302 is depressurized and driven by servo motor 102 to the rearmost crossbeam of the battery rack for lifting. Telescopic components II 209 and V 402 are depressurized and moved along the battery rack to the front end of the gantry beam via servo motor 102 for lifting. Telescopic component III 302 is depressurized and shortened. At this point, the four telescopic components lifting the battery assembly move forward via four steering wheels 600 until telescopic components II 209 and V 402 are close to the rear end face of the front mounting base, completing the third movement.

[0037] 6) The pressure relief of telescopic component III 302 is driven by servo motor 102 to the crossbeam at the rear end of the battery rack for lifting. Telescopic components II 209 and V 402 are also depressurized and driven by servo motor 102 to move along the battery rack to the front end of the front mounting bracket for lifting. Telescopic component III 302 is then depressurized. At this point, the four telescopic components lifting the battery assembly move forward via four steering wheels 600 until telescopic components II 209 and V 402 are close to the rear end face of the front bumper, completing the fourth movement.

[0038] 7) The pressure relief of telescopic component III 302 is driven by servo motor 102 to the crossbeam at the rear of the battery rack for lifting. The pressure relief of telescopic components II 209 and V 402 is driven by servo motor 102 to move along the battery rack to the front of the front bumper for lifting. The pressure relief of telescopic component III 302 is then achieved. At this point, the four telescopic components lift the battery assembly and move it forward via four steering wheels 600, completing the fifth movement. The battery assembly disassembly is then complete.

[0039] 8) The battery assembly is moved from the equipment by crane for maintenance.
