Description

Technical Field

[0001] This utility model relates to the field of mobile hoisting technology, specifically to a high-load-bearing armored protective hoisting wheel. Background Technology

[0002] A hanging rail and roller structure is a device used to achieve sliding and translational movement of objects, widely used in doors and windows, industrial equipment, and other fields. Machine tools require armored bellows for protection during operation, and these bellows need to move synchronously with the machine tool.

[0003] Existing machine tool armor wall-type protective hanging wheel systems have three major problems: 1. Limited load-bearing capacity, only able to support armor protection cavities under 100kg, cannot be adapted to extra-wide (e.g., width > 2m) or extra-large (e.g., length > 5m) wall-mounted armor protection cavities, and is prone to malfunctions such as deformation of the hanging wheels and sagging of the cavities; 2. Poor synchronization between the hanging wheel system, the bellows, and the machine tool can easily generate additional stress during operation, leading to cracking, wear, and other damage to the armored protective bellows due to concentrated preload. 3. The frictional losses between the rollers and guide rails, and between the bearings and the hanging plate are large, and there is a lack of effective lubrication structure, resulting in a short overall service life of the rollers.

[0004] Therefore, it is necessary to design a hanging wheel system that takes into account high load-bearing capacity, low stress, and long service life to solve the pain points of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a high-load-bearing armored protective roller. By optimizing the material of the roller body, the strength of the roller body is enhanced, and the overall load-bearing capacity is improved. Subsequently, the roller can realize the translation, rotation, and swing of the armored cavity through the first and second connecting parts, which can be easily adjusted synchronously with the movement of the machine tool. Then, the lubrication of the device is increased by using a POM plate and oilless bearings. At the same time, the POM plate can reduce the coefficient of friction, slow down the wear rate of the device, and increase its service life, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-load-bearing armored wall-type protective hanging wheel, comprising: The main body of the lifting wheel; The top of the main body of the hanging wheel has a downwardly extending storage groove. A first connector is movably installed in the storage groove. A hanging plate is movably connected in the storage groove through a second connector. Rollers are installed on both sides of the upper end of the hanging plate. POM plates are installed on both sides of the hanging plate and are located between the rollers.

[0007] Preferably, the first connecting member includes a cylindrical rod, one end of which is threaded, and a limiting seat is fixed at the end of the cylindrical rod away from the thread. An oilless bearing is installed on the outer side of the cylindrical rod, and the oilless bearing is fixedly embedded inside the main body of the hanging wheel. The limiting seat is located in the storage groove.

[0008] Preferably, the lower end of the hanging plate and the outer side of the hanging wheel body are provided with through holes, and the second connecting member includes a long bolt, which passes through the through holes in the hanging wheel body and the hanging plate and is threadedly connected to a limit nut.

[0009] Preferably, both sides of the upper end of the hanging plate are fixed with a fixed shaft, and the roller is rotatably mounted on the outside of the fixed shaft.

[0010] Preferably, a countersunk hole is provided on the outer side of the POM board, and an installation screw is provided in the countersunk hole. The installation screw passes through the POM board and is threadedly connected to the hanging plate.

[0011] Preferably, the POM plate has a circular hole, and the POM plate is sleeved on the outside of the fixed shaft through the circular hole, and the thickness of the POM plate is less than the distance between the hanging plate and the roller.

[0012] Preferably, the roller is slidably disposed within a metal track, and the lower part of the roller body is connected to the machine tool's armored protective cavity via a first connector.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model connects the main body of the hanging wheel to the armored cavity through the first connecting member. At the same time, the first connecting member and the main body of the hanging wheel are rotatably connected through an oilless bearing, which can avoid the armored cavity from being out of sync when moving and turning during the operation of the machine tool. The second connecting member can realize the swing of the main body of the hanging wheel. In addition to the extra stress caused by "asynchrony" during operation, the POM plate has self-lubricating properties, which can not only reduce the friction coefficient between the hanging plate and the metal track and improve the flexibility of the device, but also protect the hanging plate and prevent the hanging plate from contacting and rubbing against the metal track, which can effectively extend the service life of the hanging wheel.

[0014] 2. This utility model uses a POM board to be installed on a hanging plate via mounting screws, which facilitates the replacement of the POM board and reduces the maintenance cost of the hanging wheels. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] This utility model provides, for example Figures 1-5 The high-load-bearing armored wall-type protective hanging wheel shown includes: Hanging wheel body 1; The top of the main body 1 of the hanging wheel has a downwardly extending storage groove 2. A first connector 3 is movably installed in the storage groove 2. A hanging plate 5 is movably connected in the storage groove 2 through a second connector 4. Rollers 6 are installed on both sides of the upper end of the hanging plate 5. POM board 7 (polyoxymethylene resin board) is installed on both sides of the hanging plate 5. The POM board 7 is located between the rollers 6. The first connecting piece 3 connects the main body 1 of the hanging wheel to the armored cavity. The first connecting piece 3 and the main body 1 of the hanging wheel are rotatably connected by an oilless bearing 34, which can prevent the armored cavity from moving and turning out of sync during the operation of the machine tool. The second connecting piece 4 can realize the swing of the main body 1 of the hanging wheel. In addition to the extra stress caused by "asynchrony" during operation, the POM plate 7 has self-lubricating properties, which can not only reduce the friction coefficient between the hanging plate 5 and the metal rail and improve the flexibility of the device, but also protect the hanging plate 5 and prevent the hanging plate 5 from contacting and rubbing against the metal rail, which can effectively extend the service life of the hanging wheel.

[0019] The main body of the lifting wheel 1 is made of high-strength alloy material (such as 45 steel with heat treatment). By optimizing the wheel body wall thickness (8-12mm) and the diameter of the roller 6 (15-20mm), the overall load-bearing performance is improved. It can stably bear the ultra-wide and ultra-large armored protective bladder of 100-300kg, and avoid the bladder sagging or the lifting wheel deformation.

[0020] Among them, such as Figure 2 As shown: The first connecting member 3 includes a cylindrical rod 31, one end of which is provided with a thread 32. A limiting seat 33 is fixed to the end of the cylindrical rod 31 away from the thread 32. An oilless bearing 34 (model SF-1 optional) is installed on the outer side of the cylindrical rod 31. The oilless bearing 34 is fixedly embedded inside the main body 1 of the hanging wheel. The limiting seat 33 is located in the receiving groove 2. By setting the structure of the first connecting member 3, it can be connected to the moving parts of the machine tool through the thread 32, and the oilless bearing 34 can realize the flexible connection between the first connecting member 3 and the main body 1 of the hanging wheel, realizing the 60° rotation of the first connecting member 3 without dead angle. The limiting seat 33 provides stability between the cylindrical rod 31 and the main body 1 of the hanging wheel, preventing the first connecting member 3 from separating from the main body 1 of the hanging wheel.

[0021] Furthermore, such as Figure 3 As shown: Both the lower end of the hanging plate 5 and the outer side of the hanging wheel body 1 are provided with through holes 8. The second connecting piece 4 includes a long bolt 41, which passes through the through holes 8 on the hanging wheel body 1 and the hanging plate 5 and is threadedly connected to a limit nut 42. The second connecting piece 4 is movably connected to the hanging wheel body 1 and is designed to swing within a ±15° range. By setting the structure of the second connecting piece 4, the connection between the hanging plate 5 and the hanging wheel body 1 can be realized, and the hanging wheel body 1 can also swing back and forth on the hanging plate 5 to eliminate prestress.

[0022] Preferred, such as Figure 4 As shown: Fixed shafts 9 are fixed on both sides of the upper end of the hanging plate 5. Rollers 6 are rotatably mounted on the outside of the fixed shafts 9. The fixed shafts 9 enhance the stability of the rollers 6 on the hanging plate 5, so that the rollers 6 are stably placed in the metal track.

[0023] It is worth noting that, such as Figure 4 As shown: A countersunk hole is provided on the outer side of the POM plate 7, and an installation screw 10 is provided in the countersunk hole. The installation screw 10 passes through the POM plate 7 and is threadedly connected to the hanging plate 5. With the cooperation of the installation screw 10, it is convenient to install the POM plate 7, and it is also convenient to replace the POM plate 7 to prevent the hanging plate 5 from contacting the metal track after the POM plate 7 is excessively worn.

[0024] In a further preferred embodiment, such as Figure 4 As shown: A circular hole 11 is provided on the POM plate 7. The POM plate 7 is sleeved on the outside of the fixed shaft 9 through the circular hole 11. The thickness of the POM plate 7 is less than the distance between the hanging plate 5 and the roller 6. By providing a circular hole 11 on the POM plate 7, it is convenient to use the fixed shaft 9 to limit the POM plate 7 and ensure the stability of the POM plate 7.

[0025] In addition, such as Figure 5 As shown: The roller 6 is slidably set in the metal track. The lower part of the hanging wheel body 1 is connected to the armor protection cavity of the machine tool through the first connecting piece 3. Through the cooperation between the roller 6 and the metal track, the armor protection cavity can be moved by the hanging wheel to ensure synchronous movement with the machine tool.

[0026] In practical use, the first connecting piece 3 is connected to the protective cavity of the machine tool, and the roller 6 is placed in the metal rail. When the machine tool is running, the protective cavity moves through the hanging wheel. The first connecting piece 3 is rotatably connected to the hanging wheel body 1 through the oilless bearing 34, which can achieve 360° rotation. The second connecting piece 4 can make the hanging wheel body 1 swing under the hanging plate 5, releasing the preload of the protective cavity and avoiding local preload concentration that could cause the protective cavity to crack. When the roller 6 is displaced inside the metal guide rail, the POM plate 7 can replace the metal for direct friction, using its self-lubricating properties to reduce the coefficient of friction (coefficient of friction ≤ 0.15). The POM plate 7 can prevent wear between the hanging plate 5 and the metal rail, extending its service life.

[0027] 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.
