Description

Technical Field

[0001] This utility model relates to the field of inclined shaft related equipment, specifically a device for fixing the main shaft of the floating sheave of an inclined shaft hoist. Background Technology

[0002] During the installation and trial operation of the hoist and the floating sheave, the floating sheave rotates synchronously on the main shaft and cannot swing normally left and right. Especially when the hoist moves upward and winds up the steel rope, the wire rope is disordered on the drum, causing it to squeeze against each other and making it impossible to maintain a uniform speed of ascent and descent. This situation seriously shortens the service life of the wire rope and poses a significant potential risk to the safe use of the hoist.

[0003] In addition, the fixing method at both ends of its spindle is too simple, resulting in insufficient load-bearing capacity and short service life. Utility Model Content

[0004] The purpose of this invention is to provide a device for fixing the main shaft of the floating sheave of an inclined shaft hoist that ensures the stability and reliability of the conveying process, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a main shaft fixing device for a floating sheave of an inclined shaft hoist, comprising a main shaft and reinforcing and limiting structures fixedly installed near both ends of the main shaft. The reinforcing and limiting structures include clamps. Two symmetrically arranged clamps are fixedly fitted near both ends of the main shaft. Several mounting holes are opened on both sides of the clamps, and bolts are installed inside the mounting holes. A clamp inclined side plate is fixedly connected to the top side wall of the clamp at the bottom position, and a base plate is fixedly connected to the bottom of the clamp inclined side plate. The bottom side wall of the clamp at the bottom position is fixedly connected to the other side wall of the base plate. Mounting base structures are fixedly installed at both ends of the main shaft. A guide wheel structure is slidably fitted on the main shaft.

[0006] Preferably, the connection area between the bottom clamp and the clamp's inclined side plate is welded, and the connection area between the bottom clamp and the base plate is also welded.

[0007] Preferably, the mounting base structure includes a top seat and a base. The top seat and the base are symmetrically arranged at both ends of the main shaft. Several first fastening bolts are provided on both ends of the base. The top seat is installed to the base by several second fastening bolts.

[0008] Preferably, the base is T-shaped, and reinforcing ribs are fixedly provided on the right-angled sides of the base.

[0009] Preferably, the guide wheel structure includes a hub and a guide sleeve. The guide sleeve is fitted onto the main shaft, and the outer circumferential side of the guide sleeve is fixedly connected to the inner ring sidewall of the hub by a number of annularly arranged connecting ribs.

[0010] Preferably, the outer circular sidewall of the hub has an annular groove with a V-shaped cross-section.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by fixing and installing a reinforcing limiting structure at both ends of the spindle, the stability of the spindle in the vertical direction is significantly enhanced. The reinforcing limiting structure consists of a clamp, mounting holes, clamp inclined side plates and a base plate, and is fastened to the spindle by bolts to ensure a stable connection. This structural design not only improves the stability of the spindle, but also helps to extend the service life of the spindle.

[0012] Secondly, the guide wheel structure that is slidably mounted on the main shaft can slide freely, playing the role of guiding and supporting the floating head wheel, ensuring that the floating head wheel moves smoothly horizontally in the inclined shaft, which helps the inclined shaft hoist to operate safely and efficiently.

[0013] Furthermore, the welding connection between the bottom clamp and the clamp's inclined side plate and the bottom plate not only ensures the structural integrity but also enhances the overall load-bearing capacity and extends the service life. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The diagram shows a fixing device for the main shaft of a floating sheave of an inclined shaft hoist, including a main shaft 1 and reinforcing and limiting structures 2 fixedly installed near both ends of the main shaft 1. The reinforcing and limiting structures 2 include clamps 21. Two symmetrically arranged clamps 21 are fixedly fitted near both ends of the main shaft 1. Several mounting holes 22 are opened on both sides of the clamps 21. Bolts 25 are installed inside the mounting holes 22. A clamp inclined side plate 23 is fixedly connected to the top side wall of the clamp 21 at the bottom position. A base plate 24 is fixedly connected to the bottom of the clamp inclined side plate 23. The bottom side wall of the clamp 21 at the bottom position is fixedly connected to the other side wall of the base plate 24. Mounting base structures 3 are fixedly installed at both ends of the main shaft 1. A guide wheel structure 4 is slidably fitted on the main shaft 1.

[0022] It is worth noting that the main shaft 1, as the core component of the entire device, has a reinforcing and limiting structure 2 fixedly installed at both ends. The reinforcing and limiting structure 2 consists of a clamp 21, mounting holes 22, clamp inclined side plates 23, and a base plate 24. The clamps 21 are symmetrically arranged at both ends of the main shaft 1 and are fastened to the main shaft 1 by bolts 25 inside the mounting holes 22, ensuring a stable connection between the clamps 21 and the main shaft 1. The clamp inclined side plate 23 is fixedly connected to the top side wall of the clamp 21 at the bottom position, and the bottom of the clamp inclined side plate 23 is then fixedly connected to the base plate 24. At the same time, the bottom side wall of the clamp 21 at the bottom position is also fixedly connected to the other side wall of the base plate 24. This structural design enhances the vertical stability of the main shaft 1. In addition to ensuring stability, a guide wheel structure 4 is slidably sleeved on the main shaft 1. The guide wheel structure 4 can slide freely on the main shaft 1. During operation, the guide wheel structure 4 guides and supports the floating head wheel, ensuring that the floating head wheel can move smoothly horizontally in the inclined shaft. The floating head wheel main shaft fixing device of this inclined shaft hoist achieves stable support and guidance for the floating head wheel through the synergistic effect of the reinforcing limit structure 2, the mounting base structure 3 and the guide wheel structure 4, ensuring the safe and efficient operation of the inclined shaft hoist. Moreover, it is assembled with bolt parts 25, and the reinforcing limit structure 2 can be subsequently added to the main shaft 1 to extend its service life without disassembling the main shaft 1 for addition, thus improving work efficiency.

[0023] Please see Figure 1 , Figure 4 and Figure 5The connection area between the bottom clamp 21 and the clamp inclined side plate 23 is welded, and the connection area between the bottom clamp 21 and the bottom plate 24 is also welded.

[0024] The welding connection method not only ensures the structural robustness, but also increases the overall stability by welding into a triangular shape, thus improving the overall load-bearing capacity. The weld points are finely processed with smooth surfaces, reducing stress concentration and effectively preventing loosening or breakage due to long-term use. In addition, this welding connection method simplifies the installation steps and improves assembly efficiency, making the installation of the entire fixing device on the inclined shaft hoist more convenient and faster.

[0025] Please refer to Figure 1 and Figure 2 The mounting structure 3 includes a top seat 31 and a base 32. The top seat 31 and base 32 are symmetrically arranged at both ends of the main shaft 1. Several first fastening bolts 33 are provided on both ends of the base 32. The top seat 31 is installed together with the base 32 by several second fastening bolts 34 to form a stable mounting structure. The first fastening bolts 33 and the second fastening bolts 34 are all high-strength bolts, which ensures a tight connection between the mounting structure 3 and the main shaft 1 and effectively prevents loosening caused by vibration or external impact. The design of the top seat 31 and the base 32 not only enhances the support stability of the main shaft 1, but also facilitates the subsequent maintenance and repair of the main shaft 1. In addition, the surfaces of the top seat 31 and the base 32 are treated with anti-corrosion, which improves their corrosion resistance, extends their service life, and ensures the long-term stable operation of the inclined shaft hoist.

[0026] See Figure 2 The base 32 is T-shaped, and a reinforcing rib 35 is fixedly provided on the right-angled side of the base 32. The reinforcing rib 35 further enhances the structural strength of the base 32, enabling it to maintain higher stability and durability when facing the complex mechanical environment generated during the operation of the inclined shaft hoist.

[0027] See Figure 1 , Figure 2 and Figure 3 The guide wheel structure 4 includes a hub 41 and a guide sleeve 43. The guide sleeve 43 is sleeved on the main shaft 1. The outer side of the guide sleeve 43 is fixedly connected to the inner ring side wall of the hub 41 by a number of annularly arranged connecting ribs 42.

[0028] The connecting ribs 42 are evenly distributed to ensure the overall rigidity and stability of the guide wheel structure 4. The outer edge of the hub 41 is provided with a wear-resistant layer, which is made of high-hardness and wear-resistant material, effectively improving the service life of the guide wheel structure 4 and reducing wear problems caused by long-term friction.

[0029] Please see Figure 3The outer circular sidewall of the hub 41 is provided with an annular groove 44, and the cross-section of the annular groove 44 is V-shaped.

[0030] The V-shaped annular groove 44 is designed to increase the surface area of ​​contact between the guide wheel structure 4 and the wire rope, reduce the risk of the wire rope falling off, and thus improve the stability of the wire rope guidance.

[0031] 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 and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
