Technical Field

[0001] The utility model relates to an auxiliary device, and more specifically to a supporting wheel disassembly and assembly auxiliary device. Background Art

[0002] In crawler walking equipment such as crawler excavators, track rollers are installed under the crawler beam. The track rollers are located between the crawler and the crawler beam and bear the weight of the entire equipment. Therefore, the track rollers are prone to oil leakage, sticking and other faults, and often need to be disassembled, replaced and maintained.

[0003] The track rollers are located under the track beam, and the operating space for disassembly, assembly and replacement is small. The existing lifting or handling equipment is of little use during the disassembly, assembly and replacement process, and it is often necessary to move and lift the track rollers to the installation position under the track beam manually. Since the track rollers are made of steel, they are heavy, especially for large crawler walking equipment. Therefore, there are safety hazards in the process of disassembly, assembly and replacement of the track rollers, and the maintenance efficiency is low. Utility Model Content

[0029] The specific implementation scheme is described below with reference to the accompanying drawings.

[0030] Figure 1 A track wheel disassembly and assembly auxiliary device in this embodiment is shown, and the track wheel disassembly and assembly auxiliary device is used for disassembling and assembling track wheels on crawler walking equipment.

[0031] The auxiliary device for disassembling and assembling the supporting wheel comprises: a base frame 1, a slide frame 2, a lifting and lowering device 3, a bracket 5, etc.

[0032] The base frame 1 is provided with legs for supporting on the ground. The bottom of the slide 2 is provided with rollers 22 for rolling on the base frame. The lifting and supporting device 3 is installed on the slide 2. The bracket 5 is fixed on the platform at the top of the lifting and supporting device 3, and the supporting wheels 4 can be placed on it.

[0033] like Figure 2 As shown, the chassis 1 is composed of two parallel longitudinal beams 11 and a plurality of transverse beams 12 whose two ends are fixedly connected to the corresponding longitudinal beams 11, forming a rectangular frame structure. The longitudinal beams 11 are provided with a rolling track for the rollers 22 to roll on. Specifically, the longitudinal beams 11 are composed of angle steels, so that the rolling track is formed thereon.

[0034] Universal wheels 13 are installed at the four corners of the bottom of the chassis 1, and the universal wheels 13 act as supporting legs. When disassembling and assembling the supporting rollers, after the crawler beam is supported, one end of the chassis 1 is extended under the crawler walking device, and the other end is located outside the crawler beam, so that the chassis 1 straddles the crawler. The chassis 1 can be adjusted to a suitable position through the rollers 13, which is convenient for disassembling and assembling the supporting rollers 4.

[0035] The carriage 2 is a rectangular frame structure, and the upper roller 22 is arranged at the lower side of the end in the length direction. After the base frame 1 is placed in place, the carriage 2 is placed on the base frame 1, and the carriage 2 moves to the bottom of the crawler beam to the position where the supporting wheel 4 is removed or installed.

[0036] The lifting and lifting device 3 is a scissor lift with a scissor structure, the base of which is composed of a carriage 2, and the lifting power device of which is composed of a screw rod 33 whose two ends are respectively connected to the carriage 2 and the scissor arm connecting rod 32 in the scissor structure. The screw rod 33 is connected to the carriage 2 and is threadedly connected to the scissor arm connecting rod 32 in the scissor structure. When the screw rod 33 is rotated, the screw rod can push the scissor arm connecting rod 32 to move, thereby lifting the scissor lift.

[0037] like Figure 3 As shown, the carriage 2 constitutes the base of the scissor lift, and the side beams on both sides thereof are made of channel steel, and the channel structure thereof forms the sliding track 21 of the scissor lift. In the scissor structure, the two ends of one scissor arm connecting rod 32 are rotatably connected to the carriage 2, and the two ends of the other scissor arm connecting rod 32 are installed with pulleys, which slide on the base track 21 on the carriage 2 through the pulleys, thereby realizing the lifting and lowering of the platform at the top of the scissor lift. The screw rod 33 is rotated, and the screw rod 33 can push the scissor arm connecting rod 32 to move, thereby realizing the lifting and lowering of the scissor lift.

[0038] The platform at the top of the scissor lift is composed of two parallel grooved tracks 34 , and the pulleys at the upper ends of the scissor arms 32 in the scissor structure are located in the track grooves of the grooved tracks 34 .

[0039] The bracket 5 is composed of two parallel bearing slats, and the two ends of the two bearing slats are fixedly connected to the two grooved rails 34. The middle of the bearing slats is provided with an arc depression that can match the cylindrical surface of the supporting wheel. The arc depression can make the supporting wheel be placed on the bracket securely without shaking.

[0040] like Figure 3 As shown, the two bearing strips are the first bearing strip 51 and the second bearing strip 52, wherein the first bearing strip 1 is fixedly connected to the grooved track 34. The end of the second bearing strip 52 is bent to form a sliding guide portion 53 that matches the grooved track, and a locking bolt 54 for locking the sliding guide portion and the grooved track is provided on the sliding guide portion 53. After the locking of the locking bolt 54 is released, the position of the second bearing strip 52 can be moved to adjust the distance between the first bearing strip 51 and the second bearing strip 52 to adapt to the corresponding axial length of the supporting wheel 4.

[0041] In the present embodiment, when installing the supporting roller 4, after the track beam is raised, one end of the chassis 1 is extended under the crawler walking device, and the other end is located outside the track beam, so that the chassis 1 is placed on the crawler, the slide 2 is placed on the chassis, and the supporting roller 4 is placed on the bracket 5, and the chassis 1 and the slide 2 are moved to move the supporting roller 4 to the position just below the installation position, and the supporting roller 4 is lifted by the scissor lift 3, so that the supporting roller 4 can be conveniently fixed on the track beam by the mounting bolts. When removing the supporting roller 4, the chassis 1 and the slide 2 are moved and the lifting and lifting device is lifted, and the mounting bolts of the supporting roller 4 can be removed after the supporting roller 4 to be disassembled is lifted by the bracket 5, and then the lifting and lifting device 3 is lowered to move the slide 2 out from under the track beam. The supporting roller disassembly and assembly auxiliary device in the present embodiment facilitates the lifting and lowering of the supporting roller in the narrow space under the track beam, and is safe to operate, reduces labor intensity, and improves work efficiency.
