Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a hoisting device. Background Art

[0002] Scraper conveyors, scraper transfer machines, and crushers (hereinafter referred to as the "three machines") are essential components of specialized conveying equipment in coal mines. The power unit is the source of power and directly impacts the overall operation of the equipment. The quality of overhaul of the power unit of these "three machines" is directly related to the proper functioning and efficiency of the conveying equipment. Reducer maintenance is crucial to the quality of equipment maintenance. Reducers vary in structure depending on their function. Some heavy-duty planetary reducers for mining are designed with a single-piece cast reducer housing.

[0003] The high-speed shaft of this type of reducer is assembled by assembling the high-speed shaft assembly, adjusting the clearance, then hoisting the entire assembly horizontally, installing it into the high-speed shaft bearing hole, and then adjusting and tightening it. The assembled high-speed shaft assembly weighs approximately 130-280kg, and a crane is required to hoist the high-speed shaft in conjunction with it. Traditionally, slings have been used for hoisting. To adjust the high-speed shaft assembly to a horizontal position and align it with the reducer housing, multiple lifting points must be selected during assembly, which takes a long time to adjust and consumes a lot of assembly manpower. Utility Model Content

[0004] The utility model provides a hoisting device to solve the problem in the prior art that a high-speed shaft of a speed reducer is difficult to hoist and assemble.

[0005] In order to solve the above problems, the utility model provides a lifting device, including: a horizontal beam, wherein the horizontal beam has a plurality of lifting holes distributed along the length direction, and the lifting holes are used to connect with the hook of the lifting equipment; a vertical beam, the upper end of the vertical beam is fixedly connected to one end of the horizontal beam; a fixed cylinder, which is fixedly connected to the lower end of the vertical beam, the length direction of the fixed cylinder is parallel to the length direction of the horizontal beam, and the fixed cylinder is used to be sleeved on an axis structure to lift the axis structure.

[0006] In this solution, the arrangement of horizontal beams, vertical beams, and a fixed tube creates a C-shaped lifting device. Once the fixed tube is mounted on the shaft structure, the lifting device does not interfere with the housing when connected to the housing. Multiple lifting holes allow the position of the hook to be adjusted, thereby adjusting the center of gravity and the shaft structure to the appropriate angle for easy connection to the housing. Furthermore, the multiple lifting holes allow for adaptability to shafts of varying sizes, enhancing versatility. This lifting device can be used for applications such as assembling a high-speed shaft of a reducer with a housing.

[0007] Furthermore, the lower end of the vertical beam has multiple mounting positions along the height direction, and the fixing tube can be connected to different mounting positions to adjust the position on the vertical beam. In this way, the position of the fixing tube can be adjusted according to actual usage to adjust the angle of the shaft structure.

[0008] Furthermore, the hoisting device further comprises a fastening assembly, which securely connects the fixing cylinder and the vertical beam, thereby achieving a reliable connection between the fixing cylinder and the vertical beam, and allowing the fixing cylinder to be disassembled and the installation position to be adjusted.

[0009] Furthermore, the fastening assembly includes a bolt and a spring washer. The bolt passes through the vertical beam and is threadedly connected to the fixing tube. The spring washer is sleeved on the bolt and located between the nut of the bolt and the vertical beam. The bolt and spring washer connection has a simple structure and is easy to assemble and disassemble.

[0010] Furthermore, the fastening components are multiple groups, and the multiple groups of fastening components jointly fix the fixing cylinder. The connection is performed by multiple groups of fastening components, thereby improving the reliability of the connection.

[0011] Furthermore, the inner wall of the fixing cylinder is provided with an anti-slip structure to increase the friction with the shaft structure. By providing the anti-slip structure, the connection security between the fixing cylinder and the shaft structure is improved, and the shaft structure is prevented from accidentally falling out.

[0012] Furthermore, the anti-slip structure is a plurality of annular ribs, which are arranged at intervals along the axial direction of the fixing tube, so as to prevent the shaft structure from falling out of the fixing tube.

[0013] Furthermore, the cross beam and the vertical beam are an integrated structure, which has high strength.

[0014] Furthermore, the connection between the horizontal beam and the vertical beam has a transition arc surface, which avoids stress concentration at the connection position and improves the structural strength.

[0015] Furthermore, a reinforcing rib is provided on the upper side of each of the lifting holes, so as to ensure the structural strength and bearing capacity of the beam.

[0016] The technical solution of the present invention is applied to provide a lifting device, comprising: a horizontal beam having a plurality of lifting holes distributed along its length, the lifting holes being used to connect to a hook of a lifting device; a vertical beam having its upper end fixedly connected to one end of the horizontal beam; and a fixing cylinder fixedly connected to the lower end of the vertical beam, the length direction of the fixing cylinder being parallel to the length direction of the horizontal beam, the fixing cylinder being used to be mounted on a shaft structure to lift the shaft structure. In this solution, the arrangement of the horizontal beam, the vertical beam, and the fixing cylinder makes the lifting device a C-shaped structure. After the fixing cylinder is mounted on the shaft structure, when connected to the housing, the lifting device will not interfere with the housing. The position of the hook can be adjusted through the plurality of lifting holes, thereby adjusting the center of gravity and adjusting the shaft structure to a suitable angle for easy connection to the housing. Furthermore, the plurality of lifting holes can adapt to shaft structures of different sizes, thereby improving versatility. The lifting device can be used for assembling the high-speed shaft of a reducer with a housing.

[0017] By using this design's lifting device, you can use a bridge crane to lift the reducer's high-speed shaft and adjust its position. This lifting device allows you to hoist the reducer's high-speed shaft horizontally. Install the reducer's high-speed shaft assembly into its mounting hole. Because the high-speed shaft assembly's bearings, bearing seats, and other accessories fit tightly with the reducer, horizontal hoisting of the high-speed shaft assembly makes it easier to install it in its proper location. After installation, lower the hook and easily remove the lifting device. BRIEF DESCRIPTION OF THE DRAWINGS
