Description

Technical Field

[0001] The utility model relates to the technical field of hot-fitting gear hoisting equipment, in particular to a hot-fitting gear hoisting and mating tool. Background Art

[0002] A gear is a mechanical transmission element, usually composed of two or more gears. The function of a gear is to convert rotational motion and torque into rotational motion and torque, and is used to control the motion and power transmission of mechanical equipment. Generally, the inner hole of a gear is in an interference fit with the shaft. When installing, the sprocket must be heated according to the principle of thermal expansion and contraction, so that the gear hole diameter becomes larger. After measuring the shaft hole size with a caliper and ensuring a proper fit, assembly can be carried out. Normally, when assembling a gear, the gear is usually heated and then hoisted and mated through the gear's own hoisting hole using a lifting lug, shackle, and chain block. However, the following problems often occur in this process: When the gear has its own hoisting hole, after the gear is heated, the hoisting hole diameter also changes, resulting in a too small safety factor for use and an increased safety risk; when the gear has no hoisting hole, after the gear is heated, only 2 to 3 maintenance personnel can cooperate to manually carry the heated gear for mating assembly, which greatly increases the safety risk in this process. Content of the Utility Model

[0003] In view of the above technical problems, the utility model provides a hot-fitting gear hoisting and mating tool.

[0004] To achieve the above object, the technical solution of the utility model is specifically as follows:

[0005] A hot-fitting gear hoisting and mating tool, comprising:

[0006] An assembled base;

[0007] Four lifting lugs, symmetrically arranged on the assembled base for connecting with a hoisting device;

[0008] At least three vertically arranged adjusting rods, annularly distributed on the assembled base, with a mating gear placed at the center;

[0009] At least three pressing plates, respectively arranged at the tops of the adjusting rods, and the pressing plates are fixed on the upper part of the mating gear through compression nuts, so that the mating gear is locked.

[0010] The assembled base includes:

[0011] Two bottom plates, butted against each other to form a flat plate;

[0012] Two inner plates, vertically arranged at the butting end of one of the bottom plates;

[0013] Two outer plates are vertically arranged at the docking ends of its other bottom plate, and fixing nuts are arranged on the fixing holes of the outer plates. After the two bottom plates are docked with each other, the inner plate and the outer plate overlap each other, and the fixing holes on them are also communicated with each other;

[0014] The connecting bolts are fitted and installed on the fixing nuts to fix the inner plate and the outer plate to each other.

[0015] Adjusting long holes are arranged on the pressing plates.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. When the present utility model is used, the two bottom plates are fixed by connecting bolts to form a flat plate. Then, the three adjusting rods are arranged on the flat plate to complete the positioning and installation of the adjusting rods. Then, the three pressing plates and the pressing bolts press the upper edge of the mating gear firmly through the adjusting rods, and the installation of this tool can be completed.

[0018] 2. When the present utility model is used, the shackle is placed on the four lifting lugs, and the leveling and mating of the gear are completed through the cooperation of the chain hoist. The adjusting rods and the pressing plates can well ensure that the gear will not fall due to sliding during the hoisting process, thereby increasing the safety performance. Using this platform can reduce the direct contact between the operating personnel and the hot gear and reduce the risk of scalding. The four symmetric lifting lugs can well ensure the stability of the hoisting process and greatly improve the accuracy of the gear leveling and mating process.

[0019] 3. The present utility model is convenient to use. The installation can be completed by hoisting with a crane, which is time-saving and labor-saving compared with the previous manual handling and installation, and has a relatively high safety factor. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following further describes in detail the specific embodiments of the present utility model with reference to the drawings.

[0021] Figure 1 is a schematic structural diagram of the present utility model.

[0022] Figure 2 is Figure 1 an exploded view of SPECIFIC EMBODIMENTS

[0023] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0024] As Figure 1 and Figure 2As shown in the figure, a hot-fitting gear hoisting and alignment tool includes: an assembled base; four lifting lugs 7 symmetrically arranged on the assembled base for connecting with a hoisting device; at least three vertically arranged adjusting rods 4 annularly distributed on the assembled base, with the alignment gear 3 placed at the center; at least three pressing plates 2 respectively arranged at the tops of the adjusting rods 4, and the pressing plates 2 are fixed on the upper part of the alignment gear 3 through compression nuts 1 so that the alignment gear 3 is locked, and adjusting long holes are arranged on the pressing plates 2.

[0025] As Figure 1 and Figure 2 shown, the assembled base includes: two bottom plates 6 butted with each other to form a flat plate; two inner plates 10 vertically arranged at the butting end of one of the bottom plates 6; two outer plates 8 vertically arranged at the butting end of the other bottom plate 6, and fixing nuts 9 are arranged on the fixing holes of the outer plates 8. After the two bottom plates 6 are butted with each other, the inner plates 10 and the outer plates 8 overlap each other, and the fixing holes on them are also communicated with each other; connecting bolts 5 are fitted and installed on the fixing nuts 9 to fix the inner plates 10 and the outer plates 8 to each other.

[0026] When the present utility model is in use, first, the two bottom plates 6 are assembled and fixed through the connecting bolts 5 on both sides, then the three adjusting rods 4 (16mm lead screws) are arranged on the assembled base, and then the alignment gear 3 is placed at the central position of the three adjusting rods 4. The three pressing plates 2 are passed through the tops of the adjusting rods 4 and pressed on the upper end surface of the alignment gear 3, and the alignment gear 3 is fixed through the compression nuts 1. Thus, the assembly of this tool is completed. After confirming that the installation is firm before the operation, the shackle is fixed on the four lifting lugs 7, and then the chain block and the overhead crane are used in cooperation to complete the leveling and alignment of the gear. After the assembly is completed, the tool can be disassembled by removing the bolts of the symmetric base. Using this tool is safe and efficient. Since the adjusting long holes are arranged on the pressing plates 2, the pressing position of the pressing plates 2 can be adjusted according to the alignment gears 3 of different sizes, so that the present utility model can adapt to the alignment gears 3 of different sizes.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
