[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0020] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0021] The track roller is one of the four wheels and one belt of the crawler engineering machinery chassis. Its main function is to support the weight of the crawler crane and allow the crawler to move along the wheel. As the crawler crane's service life increases, the track roller is prone to damage. However, since the track roller is heavy, it is very troublesome to replace it after a failure. The conventional replacement plan requires the crawler crane to be disassembled and the crawler to be turned over as a whole. The turning process mainly requires human cooperation to achieve the lifting of the track roller, or relatively bulky lifting tools, such as existing forklifts or auxiliary equipment, are used. The tools used to install the track roller are particularly bulky and require large machinery to work together. There is also a method of installing the track roller using a crowbar and a wooden board, that is, using a simple lever principle, several people cooperate to install the track roller with a crowbar and a wooden board. This method is easy to slip off the track roller, which not only cannot guarantee the safety of the maintenance workers, but also has defects such as low installation efficiency, high labor intensity, poor safety, and complicated operation procedures. Not only is the operation process complicated, but there are also high safety risks and serious safety issues in the work.

[0022] Please refer to the attached Figure 1 To Attachment Figure 4 The invention describes a supporting wheel disassembly and assembly adjustable lifting tool and supporting wheel disassembly and assembly equipment.

[0023] This embodiment provides a support wheel disassembly and assembly adjustable lifting tool, such as Figure 1 and Figure 2 As shown, the lifting tool includes a first bracket 1 and a bracket group 2. The bracket group 2 can slide along a first direction relative to the first bracket 1. A support plate 3 is arranged on the bracket group 2. The support plate 3 is arc-shaped to adapt to the supporting roller. The supporting roller is detachable and adjustable. The lifting tool also includes a driving member, which is installed on the bracket group 2 and is used to guide the support plate 3 to move along the second direction.

[0024] The lifting device utilizes an arc-shaped support plate 3 to adapt to the supporting rollers, thereby avoiding deformation of the supporting rollers during adjustment. When in use, the support plate 3 can be used to drive the supporting rollers to slide relative to the first support plate 1 using the bracket group 2, so that the whole is moved to a suitable position. Then, the driving part is started to complete the disassembly and replacement of the old and new supporting rollers, solving the problem of disassembly and replacement of the supporting rollers of the existing crawler crane. It not only avoids the tedious operation of replacing the supporting rollers and disassembling the entire machine in the existing disassembly and assembly operation, but also reduces the safety risks of disassembly and assembly, and can effectively save equipment investment and manpower investment, thereby improving work efficiency.

[0025] Furthermore, if Figure 2 and Figure 3 As shown, the support plate 3 includes a supporting arc plate 31, which is set as an arc-shaped semicircular pipe for supporting the supporting roller, and the outer edges of the two sides thereof are welded with supporting plates 32. In actual operation, the supporting roller can be placed in the arc-shaped supporting arc plate 31, so as to realize the support of the supporting roller. Since the arc-shaped structure is not easy to connect with other components, that is, the connection is more prone to failure, therefore, a planar supporting plate 32 is additionally designed for connecting with other structures, so as to ensure the connection strength of each component of the device and the overall stability.

[0026] Optionally, the above-mentioned support plate 3 can also be replaced by multiple support bars, the middle position of the support bar is recessed downward to form an arc structure, so as to facilitate adaptation with the supporting wheel. It can be understood that the middle recessed part of the support bar can be equivalent to the supporting arc plate 31 of the present embodiment, and the positions on both sides can be equivalent to the supporting flat plate 32 of the present embodiment. In addition, in order to further improve the stability, the above-mentioned support bars are provided with at least 2, and the support bars are parallel to each other.

[0027] Furthermore, if Figure 2 and Figure 3 As shown, the bracket assembly 2 includes a supporting base plate 21, on which a guide assembly 22 is provided, and the guide assembly 22 is used to guide the support plate 3 to move along the second direction. The supporting base plate 21 is mainly used to support the driving member so that the driving member can follow the bracket to achieve movement in the first direction.

[0028] Specifically, Figure 3As shown, the guide assembly 22 includes a support guide sleeve 221 and a vertical guide column 222, the support guide sleeve 221 is sleeved on the outside of the vertical guide column 222, the vertical guide column 222 can slide along the second direction relative to the support guide sleeve 221, one of the vertical guide column 222 and the support guide sleeve 221 is connected to the support plate 3, and the other is connected to the support bottom plate 21. The guide column and the guide sleeve have good usability, and have the advantages of reliable guidance, and it is easy to ensure the distance between the support plate 3 and the support bottom plate 21, and the installation of the two is also relatively easy, and it is more reliable and easy to operate during use.

[0029] In this embodiment, the vertical guide column 222 is selected to be connected to the supporting plate 32 of the pallet 3, and the support guide sleeve 221 is fixed on the supporting base plate 21. Alternatively, it is also possible to additionally select not to provide the above-mentioned supporting plate 32, and directly connect the vertical guide column 222 to the supporting arc plate 31. In other embodiments, the vertical guide column 222 can also be connected to the supporting base plate 21 of the pallet 3, and the guide sleeve can be fixed on the supporting plate 32. No specific limitation is made here.

[0030] Furthermore, if Figure 2 As shown, the supporting base plate 21 includes a mounting position 211 , the driving member is arranged in the mounting position 211 , and the mounting position 211 is arranged at a middle position of the supporting base plate 21 .

[0031] Furthermore, the bracket group 2 includes a second bracket 4 , and a plurality of pulleys 100 are provided on the second bracket 4 . The second bracket 4 slides along the first direction relative to the first bracket 1 via the pulleys 100 .

[0032] Further, the bracket group 2 includes a third bracket 5, the third bracket 5 is connected to the supporting bottom plate 21, a plurality of pulleys 100 are arranged on the third bracket 5, and the third bracket 5 slides along the third direction relative to the second bracket 4 through the pulleys 100; The first direction, the second direction and the third direction are perpendicular to each other.

[0033] It should be noted that the main function of the above-mentioned pulley 100 is to enable the second bracket 4 and the third bracket 5 to slide in the first direction and the third direction, and to achieve precise position movement of the supporting wheel for disassembly and assembly. In this embodiment, two deep groove ball bearings are installed in the pulley 100, which are mainly used for rolling displacement on the first bracket 1 or the second bracket 4 to adjust the disassembly and installation position of the supporting wheel. The staff can select a suitable pulley 100 structure according to actual needs, and no specific limitation is made here.

[0034] Furthermore, the third bracket 5 and the supporting base plate 21 are integrally formed.

[0035] Furthermore, the driving member is a hydraulic jack.

[0036] The method of using the above-mentioned adjustable lifting tool for disassembling and assembling the supporting wheel is as follows: 1. Remove the crawler frame support of the crawler crane from the ground. If the track rollers to be replaced are on both sides of the track, the track plates should be disconnected first to ensure that there is enough space to install and remove the track rollers; 2. The adjustable lifting tool for disassembling and assembling the supporting wheels is placed under the supported crawler frame of the crawler crane, so that the first bracket 1 is perpendicular to the direction of the crawler; 3. Place the driving member, i.e. the hydraulic jack, on the supporting base plate 21, use the pulley 100 to move the second bracket 4 forward and backward, and move the third bracket 5 left and right to place the bracket in the installation or removal position of the supporting roller; 4. Use the hydraulic jack bracket to lift it vertically until it reaches the installation position. During this period, the pulley 100 on the second bracket 4 can be used to adjust the position of the supporting roller; 5. Install or remove the track wheels and the fixing bolts on the track wheels; 6. Release the hydraulic jack, pull out the bracket group 2 as a whole, adjust the position of the first bracket 1, and repeat the above steps 1 to 5 according to the actual situation until the operation is completed.

[0037] This embodiment also provides a track wheel disassembly and assembly device, which uses the above-mentioned track wheel disassembly and assembly adjustable lifting tooling.

[0038] The track roller disassembly equipment adjusts the track rollers by moving the support plate 3 in three directions, that is, the support group 2 slides on the first support 1 to achieve adjustment in the first direction, and the third support 5 slides on the second support 4 to achieve adjustment in the third direction. Finally, the driving member drives the support plate 3 and the track rollers to move in the second direction to complete the spatial adjustment of the track rollers. Finally, the workers can replace the old track rollers with the new ones, avoiding the problem of the traditional track roller disassembly and assembly operation requiring the entire track to be flipped, thereby ensuring the safety of the workers and improving the disassembly and assembly efficiency.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
