Description

Technical Field

[0001] This utility model belongs to the field of crusher technology, and in particular relates to a crusher belt replacement device. Background Technology

[0002] In the operation of crushers, especially jaw crushers and hammer crushers, belts play an indispensable role as a key component for power transmission. During belt installation, the connection between the belt and the belt shaft requires meticulous processing. It typically involves manually thinning the belt to a suitable thickness to ensure a tight fit with the belt shaft, thereby achieving efficient power transmission.

[0003] Because the fit between the belt and the belt shaft is extremely tight, disassembly during belt replacement is exceptionally difficult, requiring multiple people to work together to pry the belt off the belt shaft. This is not only time-consuming and labor-intensive, but also greatly reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a belt replacement device for a crusher to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A crusher belt changing device includes: a driving component, a drum, and a clamping component; the driving component is connected to the drum and is used to drive the drum to rotate; a pull rope is wound on the drum, and the free end of the pull rope is connected to the clamping component, which is used to clamp the belt.

[0007] As a further improvement of this utility model, the driving component includes a motor, which is mounted on the upper part of the motor base, and its output shaft is coaxially connected to the intermediate shaft of the roller through a coupling.

[0008] As a further improvement of this utility model, the driving component includes a rocker arm, which is Z-shaped and its end is connected to the intermediate shaft of the roller.

[0009] As a further improvement of this utility model, bearings are provided on the outside of the intermediate shafts on both sides of the roller, and a support is provided at the lower part of the bearing, and the support is adapted to the connection of the bearing.

[0010] As a further improvement of this utility model, the pull rope is a steel wire rope.

[0011] As a further improvement of this utility model, the pull rope is wrapped around the clamping member and bound to the clamping member.

[0012] As a further improvement of this utility model, the clamping member includes pliers.

[0013] The beneficial effects of adopting the above technical solution are as follows:

[0014] This utility model is equipped with a drive component, a roller, a pull rope, and a clamping component. In actual use, the clamping component accurately holds the belt, and after the drive component is started, it drives the roller to rotate, which in turn causes the pull rope wrapped around the roller to gradually contract, smoothly pulling the belt off the belt shaft, thus easily achieving belt disassembly. It eliminates the traditional method of manually removing the belt, greatly saving manpower and time, and significantly improving work efficiency.

[0015] Furthermore, this invention eliminates the need for perforating or otherwise damaging the belt during use, effectively preventing any form of damage and extending its service life. It also ensures the belt's performance and safety in subsequent use. Attached Figure Description

[0020] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0021] like Figures 1-3The diagram illustrates a belt changing device for a crusher, comprising: a drive component, a drum 1, and a clamping component 2. The drive component is connected to the drum 1 and is used to drive the drum 1 to rotate. In one possible embodiment, the drive component includes a motor 4, which is mounted on the upper part of a motor base 5. Its output shaft is coaxially connected to the intermediate shaft 6 of the drum 1 via a coupling. Therefore, when the motor 4 starts, it can drive the intermediate shaft 6 to rotate, thereby driving the entire drum 1 to rotate. In another possible embodiment, the drive component includes a crank handle, which is Z-shaped and its end is connected to the intermediate shaft 6 of the drum 1. The connection method between the crank handle and the intermediate shaft 6 is not limited. For example, the crank handle is welded to the intermediate shaft 6, or the end of the intermediate shaft 6 has a insertion hole, and the end of the crank handle is inserted into the insertion hole to connect with the intermediate shaft 6. Furthermore, threads that engage with each other can be provided on the insertion hole and the end of the crank handle, so that the insertion hole and the crank handle are threadedly connected. Manually cranking the crank handle drives the drum 1 to rotate synchronously with the intermediate shaft 6.

[0022] To facilitate stable placement of the roller 1, bearings 7 are provided on the exterior of the intermediate shafts 6 on both sides of the roller 1. Specifically, the bearings 7 are rolling bearings, and a support 8 is provided at the lower part of the bearing 7, with the support 8 and the bearing 7 connected at a suitable point. The inner ring of the bearing 7 is connected to the intermediate shaft 6 and rotates with the intermediate shaft 6, while the outer ring is connected to the support 8. Therefore, when the intermediate shaft 6 rotates, the inner ring rotates accordingly while the position of the outer ring remains unchanged, ensuring the stability of the roller 1.

[0023] A pull rope 3 is wound around the roller 1. In this embodiment, the pull rope 3 is a steel wire rope made of multiple strands of high-strength steel wire, capable of withstanding enormous tensile and impact loads. The free end of the pull rope 3 is connected to the clamping member 2. In this embodiment, the pull rope 3 is wound around the clamping member 2 and bound to it. The clamping member 2 is used to clamp the belt 9. Further, the clamping member 2 includes pliers, which can be commercially available pliers with a self-locking function. Further, the free end of the pull rope 3 can branch off into a branch rope, the end of which is connected to the clamping member 2.

[0024] When disassembling belt 9 using this device, the pliers clamp belt 9, and the extension direction of the pull rope 3 is at a certain angle to the running direction of belt 9. The angle is determined according to the actual needs on site. The motor 4 is started or the crank is manually operated, causing the roller 1 to rotate. The pull rope 3 on it retracts, pulling belt 9 away from the belt shaft 10, thus removing belt 9. One or more sets of this device can be used to remove belt 9 as needed. Figure 3As shown, when installing belt 9, place this device in the direction of belt 9 installation, then place both ends of belt 9 on belt shaft 10, and then use clamping member 2 to clamp belt 9. The driving member operates to drive clamping member 2 and belt 9 to move, thereby installing belt 9 on belt shaft 10, completing the replacement of belt 9. This device does not require piercing or other destructive operations on belt 9, thus effectively avoiding any form of damage to belt 9.
