[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a main shaft mounting support device for a mining hoist, including several support frames 1. A drive module 2 is fixedly mounted on the top of the support frame 1. A quick-release bearing seat 6 is provided at the top of the support frame 1. The quick-release bearing seat 6 includes a fixed seat 61 mounted on the top of the support frame 1. A movable seat 64 is provided above the fixed seat 61. Ear seats 65 are provided on both outer walls of the fixed seat 61 and the movable seat 64. A limit hole 66 is provided on one outer wall of the ear seat 65, and an embedded locking block 67 is connected inside the limit hole 66. A seat with a hole 68 is installed above the ear seat 65 on the movable seat 64. The interior of the perforated seat 68 is fitted with pins 69 from top to bottom. The interior of the fixed seat 61 and the movable seat 64 is provided with bearings 70. The outer walls of the fixed seat 61 and the movable seat 64 are provided with slots 62, and the outer sides of the fixed seat 61 and the movable seat 64 are fitted with sealing covers 63 through the slots 62. The sealing covers 63 are inserted into the interior of the slots 62 to seal one side of the fixed seat 61 and the movable seat 64. At the same time, an oil injection nozzle is provided above the movable seat 64 to add lubricant to the bearing 70 between the fixed seat 61 and the movable seat 64. An oil injection nozzle is also provided above the end face liner 7.

[0018] In this embodiment, the quick-release bearing seat 6 enables the spindle 4 to be quickly installed and removed from the top of the support frame 1, and can provide stable support and rotation for the spindle 4, thus ensuring the stability of the spindle 4's rotation.

[0019] Please see Figure 3, Figure 4 and Figure 6 The quick-release bearing housing 6 has a rotating main shaft 4 inside, and a detachable take-up roller 5 is sleeved on the outside of the main shaft 4. The take-up roller 5 is used for winding and unwinding the wire rope. One end of the main shaft 4 is fixedly connected to a coupling 3, and the end of the main shaft 4 is connected to the drive module 2 through the coupling 3. The take-up roller 5 has a two-part symmetrical structure. The take-up roller 5 is composed of a semi-annular bearing sleeve 52 in the middle and a retaining plate 51 installed at both ends of the bearing sleeve 52. The outer wall of the retaining plate 51 is provided with a positioning plate 53 with several holes.

[0020] In this embodiment, the rewinding roller 5 with a separate structure is easy to assemble and disassemble outside the main shaft 4, which improves the flexibility of disassembling the main shaft 4. The positioning plate 53 is also a separate structure with annularly distributed holes on its outside, which are used in conjunction with the insertion post 82.

[0021] Please see Figure 3 , Figure 4 and Figure 5 A quick-release bearing housing 6 is provided on one side with an end face bushing 7 that is sleeved on the outside of the main shaft 4. The end face bushing 7 includes an end face bearing 71 that is sleeved on the outside of one end of the fixed seat 61 and the movable seat 64. A housing 72 is sleeved on the outer side of one end of the end face bearing 71, and a bushing tube 73 is fixedly connected to one side of the outer wall of the housing 72.

[0022] In this embodiment, it should be noted that the sleeve 72 is sleeved on the outside of the end face bearing 71. Since the end face bearing 71 is relatively fixed with the fixed seat 61 and the movable seat 64, the end face bearing 71 is also in a fixed state. The inner wall of the sleeve 72 and the outer wall of the main shaft 4 can adopt a keyway and key connection structure, so that when the main shaft 4 rotates, it can drive the sleeve 72 and the liner 73 to rotate synchronously. The end face bearing 71 can eliminate the friction between the take-up roller 5 and the fixed seat 61 and the movable seat 64.

[0023] Please see Figure 4 and Figure 6 A locking module 8 is provided on one side of the end face liner 7. The locking module 8 is used for the fixed connection of the take-up roller 5 outside the main shaft 4. The locking module 8 includes a sliding ring 81 sleeved on the outside of the liner tube 73, and a number of annularly distributed inserts 82 are fixedly provided on one side of the outer wall of the sliding ring 81. A lower retaining ring 84 and an upper retaining ring 83 sleeved on the outside of the liner tube 73 are provided on one side of the sliding ring 81.

[0024] In this embodiment, it should be noted that the movement of the sliding ring 81 can drive the insertion post 82 to move, so that the insertion post 82 is inserted into the hole of the positioning disk 53, thereby realizing the fixed installation of the take-up roller 5 outside the main shaft 4. The inner wall of the sliding ring 81 and the outer wall of the liner 73 can adopt a keyway and key connection structure, so that when the main shaft 4 drives the housing 72 to rotate, the liner 73 can rotate synchronously, and the liner 73 drives the sliding ring 81 to rotate synchronously, so as to realize the synchronous rotation of the main shaft 4 and the take-up roller 5.

[0025] The working principle and usage process of this utility model are as follows: First, the operator puts the end face liner 7, the locking module 8 and the bearing 70 on the outside of the main shaft 4. Then, the main shaft 4 is placed on the quick-release bearing seat 6. The main shaft 4 is placed inside the fixed seat 61. The movable seat 64 is fastened to the upper part of the main shaft 4, so that the ear seats 65 on both sides of the fixed seat 61 and the ear seats 65 on both sides of the movable seat 64 are in contact. The locking block 67 is inserted into the limiting hole 66, and the pin 69 is inserted into the hole seat 68 from top to bottom to limit the locking block 67 and ensure the stability of the locking block 67 inside the limiting hole 66. The locking block 67 is used to fix the fixed seat 61 and the movable seat 64. After the quick-release bearing housing 6 is installed and fixed, the operator slides the end face bushing 7 toward one side of the quick-release bearing housing 6, so that one side of the end face bearing 71 is fitted onto the outside of the fixed seat 61 and the movable seat 64. A keyway and key connection structure can be used between the outside of the fixed seat 61 and the movable seat 64 and the inner wall of the bushing, so as to ensure that the bushing of the end face bearing 71 is relatively fixed with the fixed seat 61 and the movable seat 64, and the spindle 4 rotates inside it. Then, the sliding ring 81 is moved to the installation position of the retaining ring, and the take-up roller 5 of the separate structure is sleeved on the outside of the main shaft 4. The sliding ring 81 drives the sliding of the insertion post 82, so that the insertion post 82 is inserted into the hole of the positioning plate 53, thereby realizing the fixed installation of the take-up roller 5 on the outside of the main shaft 4. Finally, the operator secures the upper retaining ring 83 and the lower retaining ring 84 with bolts, positioning them within the space on one side of the sliding ring 81 to limit the movement of the sliding ring 81. When disassembling the above structure, the operation is performed in reverse.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
