Description

Technical Field

[0001] This utility model relates to the field of bearing cover technology, and in particular to a tool for quick disassembly and assembly of bearing covers for mining rollers. Background Technology

[0002] The crankshaft main bearing cap is a critical component in an engine, often referred to as the crankshaft main bearing cap. Its primary function is to secure and support the engine's crankshaft, located at the bottom of the engine. By mating with the bearing bush, the bearing cap ensures easy circumferential rotation of the crankshaft and limits axial runout. The bearing cap also withstands the cyclic alternating loads applied during engine operation, ensuring efficient engine performance. A crankshaft main bearing cap removal device is a tool or device specifically designed for removing crankshaft main bearing caps. Its main function is to simplify the removal process, reduce operational difficulty, and prevent damage to the bearings and other components.

[0003] Existing technologies, such as CN208342720U, disclose a convenient diesel engine main bearing cover disassembly tool, which includes a main bearing cover connecting plate and a lifting mechanism that drives the main bearing cover connecting plate to move vertically. The lifting mechanism includes an upper head and a support base, with a four-bar linkage lifting frame between the upper head and the support base. The four-bar linkage lifting frame is equipped with a screw thread adjustment mechanism that drives the four-bar linkage lifting frame to operate. The lifting structure can achieve stepless height adjustment through screw thread adjustment, resulting in more accurate adjustment. During the lifting process, the operator can sense the lifting force to avoid over-lifting and causing deformation of the main bearing cover's contact surface with the engine body. This utility model has a simple and compact structure, is easy to place, does not affect disassembly and assembly work, is low in cost, and can significantly improve worker efficiency.

[0004] To address the issue of rapid disassembly of roller bearings using existing equipment, which is limited to roller bearings of a certain size range, and requires operators to use cumbersome tools to disassemble larger bearings, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing equipment can only disassemble roller bearings within a certain size range, resulting in a limited scope of use. When the size is too large, the operator needs to change to a tool that matches the size of the roller bearing for disassembly, which is cumbersome. Therefore, this utility model proposes a tool for quick disassembly and assembly of roller bearing covers in mining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tool for quick disassembly and assembly of a mining roller bearing cover, comprising a base, a rotating column rotatably connected to the surface of the base, a rotating rod rotatably connected to the surface of the base, a hand lever fixedly connected to the surface of the rotating rod, a support rod disposed on the surface of the base, an auxiliary device disposed on the surface of the base, the auxiliary device comprising a rotating seat rotatably connected to the inner wall of the base, the rotating seat being disposed above the base, a first support rod rotatably connected to the inner wall of the rotating seat, a stop block disposed on the surface of the rotating column, the stop block being fixedly connected to the surface of the connecting seat, a threaded block disposed directly above the rotating seat, a rotating block disposed above the threaded block, the rotating block being sleeved and connected to the rotating rod, the rotating column being sleeved and connected to the rotating rod, and the insert rod being sleeved and connected to the inner wall of the spring.

[0007] Furthermore, the number of the first support rods is three sets arranged in a circular array, and the rotating seat is sleeved and connected to the surface of the rotating column.

[0008] Furthermore, the rotating column has a threaded block on its surface, and a rotating shaft is fixedly connected to the inner wall of the threaded block. The rotating shaft is arranged in three sets in a circular array.

[0009] Furthermore, a second support rod is rotatably connected to the surface of the rotating shaft, and a connecting seat is rotatably connected to the end of the second support rod away from the rotating shaft. The end of the first support rod away from the rotating seat is rotatably connected to the inner wall of the connecting seat.

[0010] Furthermore, a stop block is fixedly connected to the surface of the connecting seat, and a rotating block is fixedly connected to the upper surface of the rotating column.

[0011] Furthermore, the rotating rod has a threaded post on its surface, the threaded post is located above the rotating block, and a crossbar is fixedly connected to the surface of the threaded post. The support rod is slidably connected to the surface of the crossbar.

[0012] Furthermore, a spring is fixedly connected to the surface of the support rod, a protrusion is fixedly connected to the end of the spring away from the support rod, an insert rod is fixedly connected to the surface of the protrusion, a positioning hole is opened on the surface of the crossbar, and the insert rod is inserted into the inner wall of the positioning hole.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting an auxiliary device, the use of the support rod is more convenient when disassembling the roller bearing. The base is passed through the roller bearing, and then the rotating block is rotated, so that the rotating block drives the rotating rod to rotate. The rotating column rotates stably around the axis of the base, and then drives the threaded block to perform threaded transmission with the surface of the rotating column, so that the first support rod rotates along the axis of the rotating seat, and the second support rod also rotates along the axis of the rotating shaft. Then the first support rod and the second support rod work together to adjust the abutment block to fit against the inner wall of the roller bearing.

[0015] 2. In this utility model, after the abutment block is in contact with the inner wall of the roller bearing, pulling the protrusion causes the spring to stretch and expand under force, causing the insertion rod to leave the inner wall of the positioning hole. Then, the support rod is moved along the surface of the crossbar. When adjusted to a suitable position, the support rod abuts against the surface of the roller bearing. The protrusion is released, and the spring rebounds after being unrestrained, driving the insertion rod to be inserted into the inner wall of the positioning hole. Then, the position of the support rod is fixed. Then, the hand lever is rotated, causing the drive thread column and the surface of the rotating rod to perform threaded transmission. Then, the crossbar drives the support rod to move up and down in the vertical direction, so that the abutment block removes the roller bearing. By setting an auxiliary device, it is easy to disassemble the roller bearing, avoiding the limitations of existing equipment that can only disassemble roller bearings within a certain size range, resulting in a limited range of use. When the size is too large, the operator needs to change to a tool that matches the size of the roller bearing for disassembly, which is cumbersome. This effectively improves the ease of use and practicality of the equipment. Attached Figure Description

Detailed Implementation

[0023] Please see Figures 1-5 This utility model provides a technical solution: a tool for quick disassembly and assembly of a mining roller bearing cover, including a base 1, a rotating column 2 rotatably connected to the surface of the base 1, a rotating rod 3 rotatably connected to the surface of the base 1, a hand rod 4 fixedly connected to the surface of the rotating rod 3, a support rod 5 disposed on the surface of the base 1, and an auxiliary device 6 disposed on the surface of the base 1.

[0024] The specific setup and function of auxiliary device 6 will be explained below.

[0025] In this embodiment: the auxiliary device 6 includes a rotating seat 61, which is rotatably connected to the inner wall of the base 1. The rotating seat 61 is located above the base 1. A first support rod 62 is rotatably connected to the inner wall of the rotating seat 61. A stop block 67 is located on the surface of the rotating column 2 and is fixedly connected to the surface of the connecting seat 66.

[0026] Specifically, the number of the first support rods 62 is three sets arranged in a circular array, and the rotating seat 61 is sleeved and connected to the surface of the rotating column 2.

[0027] Specifically, the rotating column 2 has a threaded block 63 on its surface, and a rotating shaft 64 is fixedly connected to the inner wall of the threaded block 63. The rotating shaft 64 consists of three sets arranged in a ring array.

[0028] Specifically, a second support rod 65 is rotatably connected to the surface of the rotating shaft 64, and a connecting seat 66 is rotatably connected to the end of the second support rod 65 away from the rotating shaft 64. The end of the first support rod 62 away from the rotating seat 61 is rotatably connected to the inner wall of the connecting seat 66.

[0029] Specifically, a stop block 67 is fixedly connected to the surface of the connecting seat 66, and a rotating block 68 is fixedly connected to the upper surface of the rotating column 2.

[0030] Specifically, the rotating rod 3 has a threaded post 69 on its surface, which is located above the rotating block 68. A crossbar 610 is fixedly connected to the surface of the threaded post 69, and the support rod 5 is slidably connected to the surface of the crossbar 610.

[0031] Specifically, a spring 611 is fixedly connected to the surface of the support rod 5, a protrusion 612 is fixedly connected to the end of the spring 611 away from the support rod 5, an insert rod 613 is fixedly connected to the surface of the protrusion 612, a positioning hole 614 is opened on the surface of the crossbar 610, and the insert rod 613 is inserted into the inner wall of the positioning hole 614.

[0032] The effects achieved by the above components are as follows: by setting a rotating seat 61, the first support rod 62 can rotate along the axis of the rotating seat 61; by setting a threaded block 63, the second support rod 65 can be rotated along the axis of the rotating shaft 64, so that the first support rod 62 and the second support rod 65 can be adjusted at an angle to press the abutment block 67 against the inner wall of the roller bearing, and can be completely and effectively fitted to roller bearings of different sizes; by setting a rotating block 68, the rotating column 2 can be rotated; by setting a crossbar 610, the position of the two end support rods 5 can be adjusted along the surface of the crossbar 610, so that the support rods 5 fit against the surface of the roller bearing; by setting a spring 611, after the protrusion 612 loses its force, the rebound force of the spring 611 can drive the insertion rod 613 to reset, so that the insertion rod 613 is inserted into the corresponding positioning hole 614, and the position of the support rod 5 is fixed.

[0033] Working principle: By setting auxiliary device 6, the use of support rod 5 is more convenient when disassembling the roller bearing. The base 1 is passed through the roller bearing, and then the rotating block 68 is rotated, so that the rotating block 68 drives the rotating rod 3 to rotate. The rotating column 2 rotates stably around the axis of the base 1, and then drives the threaded block 63 to perform threaded transmission with the surface of the rotating column 2, so that the first support rod 62 rotates along the axis of the rotating seat 61, and the second support rod 65 also rotates along the axis of the rotating shaft 64. Then the first support rod 62 and the second support rod 65 work together to move the abutment block 67 to fit against the inner wall of the roller bearing.

[0034] After the abutment 67 is in contact with the inner wall of the roller bearing, pull the protrusion 612 to stretch and expand the spring 611, causing the insertion rod 613 to leave the inner wall of the positioning hole 614. Then move the support rod 5 along the surface of the crossbar 610. When it is adjusted to a suitable position, so that the support rod 5 abuts against the surface of the roller bearing, release the protrusion 612, and the spring 611 will rebound after being unrestrained, driving the insertion rod 613 to be inserted into the inner wall of the positioning hole 614. Then the position of the support rod 5 is fixed. Then rotate the lever 4 to make the drive threaded column 69 and the surface of the rotating rod 3 make contact. Driven by a threaded transmission, the crossbar 610 drives the support rod 5 to move up and down vertically, causing the stop block 67 to remove the roller bearing. By setting up the auxiliary device 6, it is easier to disassemble the roller bearing, avoiding the limitation of existing equipment that can only disassemble roller bearings within a certain size range, resulting in an overly limited range of applications. When the size is too large, the operator needs to change to a tool that matches the size of the roller bearing for disassembly, which is cumbersome. This effectively improves the ease of use and practicality of the equipment.
