Description

Technical Field

[0001] This utility model relates to the technical field of nylon belt traction devices, specifically to a nylon belt traction device with buffering and steering functions. Background Technology

[0002] Nylon belts are widely used as flexible traction media in equipment connections and power transmission. In traditional nylon belt traction devices, when the nylon belt moves rapidly due to external forces, a severe impact load is generated at the contact point with the guide bearing, which can easily lead to bearing deformation, wear, or even breakage, seriously affecting the service life of the equipment. In addition, the steering function of nylon belts in existing technologies usually relies on multiple sets of fixed guide wheels or complex steering mechanisms, which not only occupy a lot of space but also make it difficult to simultaneously complete buffering and direction switching under impact conditions, resulting in structural redundancy and low energy absorption efficiency.

[0003] In summary, this utility model provides a nylon belt traction device with buffering and steering functions to solve the problems existing in the prior art. Utility Model Content

[0031] Example

[0032] See Figure 1 and Figure 2 This embodiment provides a nylon belt traction device with buffering and steering functions, including a base 1, a guide 2, a bearing assembly, a buffer mechanism, and a reel 3; the guide 2 is connected to the base 1, and the base 1 is fixedly connected to the ground through a fixing pile 4.

[0033] The reel 3 is vertically fixed to the base 1 by two support frames 5. Preferably, the support frames 5 of the reel 3 are connected to the base 1 by a flange. The flange is provided with an arc-shaped adjustment groove, which is arranged along the axial direction of the reel 3. By providing the arc-shaped adjustment groove, the distance between the two support frames 5 can be adjusted to meet the installation requirements of reels 3 of different sizes.

[0034] The bearing assembly includes a first bearing 7 and a second bearing 8 arranged opposite to each other. The first bearing 7 is fixed to the base 1 by a support 9, and the second bearing 8 is connected to a buffer mechanism. The buffer mechanism is arranged on the base 1 and located below the reel 3.

[0035] The buffer mechanism includes two sets of buffer cylinders 10 arranged side by side on the base 1. The piston rods of the buffer cylinders 10 are arranged in the same direction, and the piston rods of the two sets of buffer cylinders 10 are connected by a pin. The second bearing 8 is sleeved on the pin and rotatably connected to the pin. The axial direction of the pin is perpendicular to the direction of movement of the nylon belt.

[0036] In this embodiment, the buffer cylinder 10 is a hydraulic cylinder with adjustable pressure to meet the needs of different levels of buffering conditions.

[0037] The buffer mechanism also includes a limiting seat 11, which is disposed on the base 1 along the extension and retraction path of the piston rod and is used to limit the retraction of the piston rod. The position of the limiting seat 11 is adjustable to adjust the buffer distance and meet the needs of different working conditions.

[0038] Preferably, the limiting seat 11 is provided with an elastic buffer layer, the shape of which is adapted to the contour of the pin end. The elastic buffer layer is preferably rubber. By setting the elastic buffer layer, rigid collisions can be reduced, the impact force on the bearing can be reduced, and the service life of the bearing can be extended.

[0039] In this embodiment, a nylon strip 6 is wound around the drum of the reel 3; the nylon strip 6 extends horizontally (parallel to the ground), passes around the first bearing 7 and the second bearing 8 in sequence to turn, and then is turned by the guide 2 to extend vertically (perpendicular to the ground).

[0040] Preferably, the outer ring surfaces of the first bearing 7 and the second bearing 8 are provided with nylon belt guide grooves to limit and guide the nylon belt. The bottom of the guide groove is provided with a wear-resistant layer, preferably a high wear-resistant ceramic liner. The wear-resistant layer can enhance the wear resistance and improve the service life of the bearing.

[0041] In this embodiment, a nylon strap outlet is provided on the side of the base 1, and the nylon strap outlet is perpendicular to the ground. The guide 2 is disposed at the nylon strap outlet on the base 1, and the axis of the guide groove of the guide 2 is perpendicular to the ground.

[0042] In actual use, the nylon belt 6 passes sequentially around the first bearing 7 and the second bearing 8. The nylon belt 6 is in a horizontal state and is redirected by the first bearing 7 and the second bearing 8. See [link / reference]. Figure 3 In section AA; nylon belt 6 passes through the nylon belt exit. At this point, nylon belt 6 begins to change direction from the end of the second bearing 8 to the end of the nylon belt exit. See [link / reference]. Figure 3 In the CC segment; after the nylon tape 6 passes through the nylon tape exit, it wraps around to the guide rail 2, with the nylon tape 6 perpendicular to the ground. See [link / reference]. Figure 3 The DD segment in the middle.

[0043] When the equipment is working, the nylon belt 6 is subjected to external force and suddenly accelerates rapidly; the nylon belt 6 comes into contact with the second bearing 8, and the nylon belt 6 drives the second bearing 8 to compress the piston rod of the buffer cylinder 10, and the piston rod retracts to absorb energy; the piston rod of the buffer cylinder 10 retracts a certain distance (i.e., the buffer distance, see...) Figure 3 When the pin is in section BB, it contacts the limit seat 11. At this time, the piston rod stops retracting and the second bearing 8 rotates around the pin. The nylon belt 6 moves synchronously from the position of the second bearing 8 to the nylon belt outlet position of the base, and then turns to a vertical state after passing through the guide 2.

[0044] The nylon belt traction device with buffering and steering functions provided by this utility model effectively reduces the impact load on the second bearing and extends the service life of the device by setting a buffer mechanism; the nylon belt can be steered by setting a first bearing, a second bearing and a guide, the structure is simple and easy to implement, and with the setting of the buffer mechanism, it can meet the requirement of simultaneously completing buffering and direction switching under impact conditions.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
