Description

Technical Field

[0001] This application relates to the field of construction machinery, and in particular to a bearing assembly lifting device for a tunneling machine. Background Technology

[0002] Tunneling machine bearings are important mechanical components used in various mechanisms of tunneling machines, mainly including traveling mechanisms and slewing mechanisms.

[0003] Currently, operators use wire to fix the bearing first, then lift it up to heat the bearing, and then assemble it with the main shaft. After the bearing and main shaft are installed in place, the wire needs to be broken before it can be pulled out. Therefore, the traditional hoisting method is inconvenient during the assembly of the tunneling machine main shaft bearing, which leads to time-consuming and labor-intensive assembly and thus affects work efficiency. Utility Model Content

[0004] To facilitate bearing installation for operators, improve their work efficiency, and reduce the risks associated with bearing installation, this application provides a bearing assembly lifting tool for tunneling machines.

[0005] The technical solution of the tunneling machine bearing assembly lifting tool provided in this application is as follows: A tunneling machine bearing assembly lifting tool includes a lifting tool tray and a mounting ring, wherein the lifting tool tray is provided with a mounting mechanism for clamping and installing the bearing;

[0006] The installation mechanism includes multiple insertion holes on the outside of the lifting tray, each insertion hole containing multiple corresponding bearing supports, each bearing support having multiple corresponding positioning holes extending to the top of the lifting tray, each positioning hole containing a positioning pin for positioning the bearing supports, and the top of the lifting tray containing multiple threaded holes, each threaded hole containing multiple threaded seats, each threaded seat having a corresponding lifting ring fixedly installed.

[0007] By adopting the above technical solution, the positioning pin and positioning hole can be matched with the outer diameter of multiple bearings, so that one lifting tool can assemble multiple bearings and achieve the purpose of one lifting tool for multiple uses. The bearing support rod and positioning pin are used together to ensure that the installation is firm, the disassembly and assembly are simple and easy to operate. The lifting ring is connected to the lifting tool tray to play a role in stabilizing the connection.

[0008] Preferably, one end of each of the plurality of bearing support rods is fixedly mounted with a corresponding mounting plate.

[0009] By adopting the above technical solution and setting up an installation disk, an auxiliary installation function can be achieved.

[0010] Preferably, a plurality of connecting columns are fixedly installed on the top of the spreader tray, and a corresponding mounting sleeve is fixedly installed on one end of the top of each of the plurality of connecting columns.

[0011] By adopting the above technical solution and setting up connecting columns, an auxiliary installation and connection function can be achieved.

[0012] Preferably, each of the plurality of mounting sleeves is screwed with a corresponding threaded post, one end of which is fixedly mounted with a reinforcing rod, and the other end of which is fixedly mounted with a knob.

[0013] By adopting the above technical solution, rotating the knob will cause the threaded column to rotate and move. When the threaded column moves, it will also move the reinforcing rod and make contact with the outer surface of the bearing, thereby reinforcing and positioning the bearing. Therefore, the stability and safety of bearing assembly can be improved.

[0014] Preferably, the reinforcing rod is fitted with an anti-slip pad and contacts the outer surface of the bearing.

[0015] By adopting the above technical solution and setting up anti-slip mats, the friction can be increased.

[0016] Preferably, the mounting ring is fitted with a plurality of first connecting ropes, and a corresponding nylon strap is integrally mounted on the plurality of first connecting ropes.

[0017] By adopting the above technical solution and using nylon belts, the assembly spindle will not be bumped or damaged during the installation of bearings, thus improving the protection during use.

[0018] Preferably, the nylon strap has an opening, a second connecting rope is provided in the opening, a third connecting rope is connected to the second connecting rope, and a hook adapted to the lifting ring is connected to the third connecting rope.

[0019] By adopting the above technical solution, and by setting up a hook, the lifting ring can be installed in conjunction with the lifting ring, thereby achieving the purpose of lifting.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application utilizes a lifting pallet and other components, employing a positioning pin and positioning hole to match the outer diameter of multiple bearings. This allows for the assembly of multiple bearings with a single lifting device, achieving multi-purpose functionality. The bearing support rod, in conjunction with the positioning pin, ensures secure installation, easy assembly and disassembly, and convenient operation. The lifting ring connects to the lifting pallet, providing a stable connection. Furthermore, the use of nylon straps prevents impacts to the assembled spindle during bearing installation, thus enhancing protection during use.

[0022] 2. This application employs a reinforcing rod and the like. By rotating a knob, the knob rotates and drives the threaded column to rotate and move. As the threaded column moves, it drives the reinforcing rod to move as well, and it comes into contact with the outer surface of the bearing. This allows for the reinforcement and positioning of the bearing, thereby improving the stability and safety of the bearing assembly. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0029] This application discloses a bearing assembly lifting tool for a tunneling machine.

[0030] Reference Figure 1-3A bearing assembly lifting tool for a tunneling machine includes a lifting tool tray 1 and a mounting ring 5, an installation mechanism for clamping and installing the bearing on the lifting tool tray 1, a reinforcement mechanism on the lifting tool tray 1, and a connecting mechanism on the mounting ring 5.

[0031] The installation mechanism includes multiple insertion holes 8 on the outside of the lifting tray 1, multiple bearing support rods 9 corresponding to the insertion holes 8, multiple positioning holes 11 on the bearing support rods 9 extending to the top of the lifting tray 1, positioning pins 12 for positioning the bearing support rods 9 in the positioning holes 11, multiple threaded holes 2 on the top of the lifting tray 1, multiple threaded seats 3 in each threaded hole 2, a corresponding lifting ring 4 fixedly installed on each threaded seat 3, and a corresponding mounting plate 10 fixedly installed on one end of each bearing support rod 9.

[0032] In use, the positioning pin 12 and the positioning hole 11 are matched to the outer diameter of multiple bearings, so that one lifting tool can assemble multiple bearings and achieve the purpose of one lifting tool for multiple uses. The bearing support rod 9 is used in conjunction with the positioning pin 12 to ensure that the installation is firm, the disassembly and assembly are simple and easy to operate. The lifting ring 4 is connected to the lifting tool tray 1 to play a role in stabilizing the connection.

[0033] Reference Figure 1-2 The reinforcement mechanism includes multiple connecting columns 13 fixedly installed on the top of the lifting tray 1, and each of the multiple connecting columns 13 has a corresponding mounting sleeve 14 fixedly installed at one end of its top. Each of the multiple mounting sleeves 14 has a corresponding threaded column 15 screwed into it. A reinforcement rod 17 is fixedly installed at one end of the threaded column 15, and a knob 16 is fixedly installed at the other end of the threaded column 15. An anti-slip pad is fitted on the reinforcement rod 17 and contacts the outer surface of the bearing.

[0034] In use, by rotating the knob 16, the rotation of the knob 16 will cause the threaded column 15 to rotate and move. When the threaded column 15 moves, it will cause the reinforcing rod 17 to move as well, and make contact with the outer surface of the bearing. This will reinforce and position the bearing, thereby improving the stability and safety of the bearing assembly.

[0035] Reference Figure 1 and Figure 4 The connecting mechanism includes multiple first connecting ropes 6 sleeved on the mounting ring 5, with corresponding nylon straps 7 integrally installed on the multiple first connecting ropes 6, openings 18 on the nylon straps 7, and a second connecting rope 19 inside the openings 18. A third connecting rope 20 is connected to the second connecting rope 19, and a hook 21 adapted to the lifting ring 4 is connected to the third connecting rope 20.

[0036] During use, the use of nylon strap 7 prevents the assembled spindle from being bumped or damaged during bearing installation, thus improving protection during use.

[0037] The implementation principle of the bearing assembly lifting tool for a tunneling machine according to this application embodiment is as follows: In use, the positioning pin 12 and the positioning hole 11 are matched to the outer diameter of multiple bearings, so that one lifting tool can assemble multiple bearings and achieve the purpose of one lifting tool for multiple uses. The bearing support rod 9 is used in conjunction with the positioning pin 12, so that the installation is firm, the disassembly and assembly are simple, and the operation is convenient. The lifting ring 4 is connected to the lifting tool tray 1, which plays a role in stabilizing the connection. In addition, by using nylon belt 7, the assembly of the main shaft will not be bumped during the installation of bearings, so as not to cause damage. Therefore, the protection during use can be improved.

[0038] By rotating the knob 16, the knob 16 rotates and drives the threaded column 15 to rotate and move. When the threaded column 15 moves, it drives the reinforcing rod 17 to move as well, and it comes into contact with the outer surface of the bearing. This allows for the reinforcement and positioning of the bearing, thereby improving the stability and safety of the bearing assembly.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
