Description

Technical Field

[0001] The present application relates to the technical field of tunnel boring machines, and in particular to a motor fixing mechanism of a tunnel boring machine blade drive device. Background Art

[0002] During use, the existing tunnel boring machines may experience loosening or breaking of the fixing bolts of the shovel drive motor, causing the motor to fall off. If the motor fixing bolts become loose, the shovel drive must be dismantled, hoisted, and re-tightened. If the motor fixing bolts are broken but not completely broken, the shovel drive must be dismantled, hoisted, and then the motor must be dismantled. To deal with the broken bolts, the motor fixing bolts are all high-strength, so it is not easy to remove the broken bolts in the mine, so new ones must be replaced and lifted to the surface for processing. If all the fixing bolts of the shovel drive motor are broken or loose, or partially broken and partially loose, the motor output shaft will not rotate when it is not fixed, and the motor housing will rotate, thereby breaking the motor oil pipe seat or oil pipe, causing serious oil leakage, which is more troublesome to deal with. The above situations will seriously affect production and increase production costs. Summary of the Invention

[0003] In order to make up for the above shortcomings, the present application provides a motor fixing mechanism for a shovel drive device of a tunnel boring machine, which is designed to protect and limit the fixing bolts to prevent the fixing bolts from loosening and wearing out during long-term use, thereby increasing the service life of the shovel drive motor and greatly improving the efficiency of maintenance when subsequent problems occur.

[0004] The present application provides a motor fixing mechanism for a shovel drive device of a tunnel boring machine, comprising a mounting base, a drive motor base being mounted on the mounting base, a limit mechanism being provided above the drive motor base, a fixing bolt being connected to the interior of the limit mechanism, and a top cover being connected to the top of the fixing bolt;

[0005] The limiting mechanism includes a top cover slot, an inner hexagonal positioning hole and a slot. The inner hexagonal positioning hole is opened inside the limiting mechanism, and a top cover slot is opened outside the inner hexagonal positioning hole. An outer hexagonal eaves is formed between the inner hexagonal positioning hole and the top cover slot, and slots are opened on both sides above the outer hexagonal eaves.

[0006] In the above implementation process, the limiting mechanism is used in conjunction with the fixing bolts and the top cover to ensure the sealing of the fixing bolts after the connection is completed, reduce rust, and at the same time perform additional positioning and reinforcement on the fixing bolts to reduce the loosening of the fixing bolts and reduce the overall damage to the drive motor.

[0007] In a specific embodiment, a sealed cavity is opened inside the top cover, and positioning blocks are installed on both sides of the sealed cavity.

[0008] In the above implementation process, the fixing bolt is fixed by connecting the slot and the positioning groove through the positioning block.

[0009] In a specific embodiment, a positioning stabilization groove is formed through the inside of the mounting seat and the driving motor seat, and a positioning stabilization rod is inserted into the inside of the positioning stabilization groove.

[0010] In the above implementation process, the positioning stabilizing rod provides additional reinforcement to the mounting base and the drive motor base, thereby increasing the overall service life.

[0011] In a specific embodiment, a sealing groove is opened at the lower part of the top cover slot, a sealing strip is installed at the lower part of the top cover, and the sealing strip is inserted into the sealing groove.

[0012] In the above implementation process, the sealing strip is used in conjunction with the sealing groove to reduce the entry of external dust or sewage into the hexagonal positioning hole, thereby reducing the possibility of rust on the fixing bolts and increasing the service life.

[0013] In a specific embodiment, a connecting thread hole is provided at the bottom of the mounting seat, and a sealing ring is installed inside the connecting thread hole.

[0014] In the above implementation process, the connecting thread hole is protected by the sealing ring to reduce rust and facilitate the subsequent disassembly of the mounting base.

[0015] In a specific embodiment, the number of the limiting mechanisms is several.

[0016] In the above implementation process, multiple limiting mechanisms no longer need to be used at the same time. Only multiple ones need to be connected during connection. When situations occur at different positions and maintenance is required, only additional limiting mechanisms need to be used for fixing, which can also achieve the fixing effect and improve the efficiency of maintenance and production.

[0032] See also Figure 1 The present application provides a motor fixing mechanism of a shovel drive device of a tunnel boring machine, including a mounting base 1, a driving motor base 2 is installed on the mounting base 1, a limiting mechanism 4 is arranged above the driving motor base 2, a fixing bolt 6 is connected inside the limiting mechanism 4, and a top cover 5 is connected to the top of the fixing bolt 6.

[0033] The fixing bolt 6 is positioned by the limiting mechanism 4 , thereby reducing the possibility of the fixing bolt 6 becoming loose.

[0034] See also Figure 1 The limiting mechanism 4 includes a top cover slot 401, an inner hexagonal positioning hole 402 and a slot 405. The inner hexagonal positioning hole 402 is opened inside the limiting mechanism 4. The inner hexagonal positioning hole 402 is fixed for connecting the fixing bolt 6. A top cover slot 401 is opened outside the inner hexagonal positioning hole 402. The top cover slot 401 needs to be used in conjunction with the top cover 5 to fix the top cover 5. An outer hexagonal cornice 403 is formed between the inner hexagonal positioning hole 402 and the top cover slot 401. The outer hexagonal cornice 403 ensures that the positioning block 9 can be inserted into the slot 405. Slots 405 are opened on both sides above the outer hexagonal cornice 403.

[0035] See also Figure 1 Figure 2 Figure 3 、 Figure 4 and Figure 5 A sealed cavity 7 is formed inside the top cover 5 , and positioning blocks 9 are installed on both sides of the sealed cavity 7 .

[0036] In this embodiment, the positioning block 9 realizes the connection between the slot 405 and the positioning groove 10, thereby achieving the positioning and stabilization of the fixing bolt 6 and reducing loosening.

[0037] In this application document, a positioning and stabilizing groove 11 is provided inside the mounting seat 1 and the driving motor seat 2, a positioning and stabilizing rod 3 is inserted into the positioning and stabilizing groove 11, a sealing groove 404 is provided below the top cover slot 401, a sealing strip 8 is installed below the top cover 5, and the sealing strip 8 is inserted into the sealing groove 404, a connecting thread hole 13 is provided at the bottom of the mounting seat 1, a sealing ring 12 is installed inside the connecting thread hole 13, and the number of limiting mechanisms 4 is several.

[0038] During the specific setting, the positioning stabilizing rod 3 provides additional reinforcement for the mounting base 1 and the drive motor base 2, thereby improving the overall service life. The sealing strip 8 is used in conjunction with the sealing groove 404 to reduce the entry of external dust or sewage into the hexagonal positioning hole 402, thereby reducing the possibility of rust on the fixing bolt 6 and improving the service life. The connecting wire hole 13 is protected by the sealing ring 12 to reduce rust and facilitate the subsequent disassembly of the mounting base 1. Multiple limiting mechanisms 4 no longer need to be used at the same time. Only multiple need to be connected when connecting. When situations occur at different positions and maintenance is required, only the additional limiting mechanism 4 needs to be used for fixing, which can also achieve the fixing effect and improve the efficiency of maintenance and production.

[0039] Specifically, the working principle of the motor fixing mechanism of the shovel drive device of the tunnel boring machine is as follows: when in use, first connect the drive motor to the drive motor seat 2. When connecting, insert the fixing bolt 6 into the inner hexagonal positioning hole 402 inside the limiting mechanism 4 and fix it at the same time. After the fixing is completed, the positioning groove 10 is aligned with the slot 405 inside the outer hexagonal eaves 403. At this time, connect the top cover 5 to the limiting mechanism 4, insert the top cover 5 into the top cover slot 401, and insert the positioning block 9 into the positioning groove 10 and the slot 405. Then insert the positioning stabilizing rod 3 into the positioning stabilizing groove 11, reinforce and fix the drive motor seat 2 and the mounting seat 1, and complete the installation. If the fixing bolt 6 is damaged later, only the additional fixing bolt 6 needs to be inserted into the remaining internal mechanisms of the limiting mechanism 4 to reduce disassembly and facilitate maintenance.
