Description

TECHNICAL FIELD

[0001] The utility model relates to a locking structure, specifically a belt pulley locking structure. BACKGROUND

[0002] In the running process of industrial production and various mechanical equipment, belt pulley transmission is a very common and important power transmission mode. However, the existing belt pulley locking technology and related devices have many problems to be solved.

[0003] At present, most of the devices for locking the belt of the belt pulley on the market have complex structures and are often composed of a large number of parts. These complex structures not only increase the manufacturing cost of the device, but also make the installation, debugging and maintenance work extremely cumbersome. The operator needs to have high professional skills and rich experience to correctly complete these operations, which undoubtedly raises the use threshold and reduces the work efficiency.

[0004] In terms of convenience of use, the existing devices also have obvious deficiencies. The operation process of many devices is complex, and it is necessary to use multiple tools and go through multiple steps to complete the locking work of the belt. This not only wastes a lot of time and manpower, but also is prone to errors in the operation process, affecting the normal operation of the equipment. For example, in some emergency situations, due to the inconvenience of device operation, the belt pulley cannot be locked in time and effectively, which may cause equipment failure and even safety accidents.

[0005] The existing belt pulley locking device has great limitations in the adjustment of locking force. Most devices can only provide fixed locking force and cannot be flexibly adjusted according to actual needs. However, the locking force required for the belt pulley is different in different working scenes and conditions. For example, in some high-precision mechanical equipment, a smaller locking force is required to avoid damage to the belt and belt pulley; while in some heavy-load equipment, a larger locking force is required to ensure stable transmission of power. Since the existing device cannot meet such diversified needs, its application range is greatly limited.

[0006] In summary, the existing belt pulley locking technology and device have serious deficiencies in structural complexity, convenience of use and locking force adjustment, and there is an urgent need for a belt pulley locking device with simple structure, convenient use and flexible locking force adjustment.

[0025] Please refer to Figures 1-4The utility model provides a belt pulley locking structure, including left support 1 and right support 2, and left support 1 and right support 2 are fixedly connected with adjusting support 3, and adjusting support 3 is provided with through groove 4, adjusting screw 5 is slidably connected in through groove 4, locking nut 6 is connected in the outer side of adjusting screw 5, and locking nut 6 is used for locking the relative position of adjusting screw and adjusting support 3, and locking unit 7 is arranged on the side of adjusting screw 5 close to belt pulley.

[0026] The locking unit 7 comprises a fixed box 8, a connecting frame 9 is fixedly connected to the fixed box 8, the connecting frame 9 is rotatably connected with the adjusting screw 5, a locking screw 10 is threadedly connected to the connecting frame 9, the locking screw 10 is used to adjust the relative angle of the connecting frame 9 and the locking nut 6, and a locking wheel 11 is rotatably connected to the fixed box 8 and cooperates with the belt pulley.

[0027] When in use, the left support 1 and the right support 2 are respectively located on the two sides of the belt pulley transmission belt and are symmetrically distributed, and the adjusting support 3 drives the locking unit 7 to move inward during rotation to clamp the belt, and the technical means for controlling the left support 1 and the right support 2 to move towards the middle to clamp the belt is the prior art, the locking unit 7 is connected with the adjusting support 3 through the adjusting screw 5, and the position of the adjusting screw 5 can be adjusted by loosening the locking nut 6, and when the position is adjusted to the appropriate position, the locking nut 6 can be tightened to fix the position of the locking unit 7. The locking wheel 11 in the locking unit 7 will extrude the belt during contact with the belt, so that the belt is slowed down.

[0028] The locking nut 6 is fixedly connected with a fixed baffle 12 on the outside.

[0029] The locking wheel 11 is provided with four, two are symmetrically arranged on both sides of the fixed box 8, a speed reduction belt 13 is sleeved on the outside of the locking wheel 11, and a pressurizing assembly 14 for applying pressure to the speed reduction belt 13 is further arranged at the both ends of the connecting frame 9.

[0030] When two locking wheels 11 need to contact the belt at the same time, the connecting frame 9 and the adjusting screw 5 can be rotated by loosening the locking screw 10, and at this time, an external force is applied, so that the fixed box 8 is self-adapted to rotate, so that the two locking wheels 11 extrude the belt at the same time. The locking wheel 11 rotates synchronously and drives the speed reduction belt 13 to move, and the speed reduction belt 13 cannot rotate freely under the damping action of the pressurizing assembly 14, and then the locking wheel 11 is slowed down, and the speed reduction damping of the speed reduction belt 13 controls the locking force of the locking wheel 11, and different friction plates in the friction plate assembly 16 contact the speed reduction belt 13 to achieve different speed reduction effects.

[0032] Pulling the guide rod 15 upwards makes the friction plate assembly 16 disengage from the deceleration belt 13, and then rotating the guide rod 15 can make different friction plates contact the deceleration belt 13, so as to adjust the degree of deceleration.

[0033] In addition, the device can also select a single locking wheel 11 or the deceleration belt 13 to contact the belt, and only needs to tilt the fixed box body 8 and then tighten the locking screw 10 to lock the tilt angle of the fixed box body 8, thereby realizing the single locking wheel 11 or the deceleration belt 13 contacting the belt.

The locking wheel 11 in the locking unit 7 will extrude the belt during contact with the belt, so as to slow down the belt.

[0035] When two locking wheels 11 need to contact the belt at the same time, the locking screw 10 can be loosened to make the connecting frame 9 and the adjusting screw 5 rotate, at this time, an external force is applied, and then the fixed box body 8 will automatically rotate to make the two locking wheels 11 extrude the belt at the same time. The locking wheel 11 will rotate synchronously and drive the deceleration belt 13 to move, and the deceleration belt 13 cannot rotate freely under the damping action of the pressing assembly 14, thereby slowing down the locking wheel 11, and the deceleration damping of the deceleration belt 13 controls the locking degree of the locking wheel 11, and different friction plates in the friction plate assembly 16 contacting the deceleration belt 13 achieve different deceleration effects. Pulling the guide rod 15 upwards makes the friction plate assembly 16 disengage from the deceleration belt 13, and then rotating the guide rod 15 can make different friction plates contact the deceleration belt 13, so as to adjust the degree of deceleration.

[0036] In addition, the device can also select a single locking wheel 11 or deceleration belt 13 to contact with the belt, only need to tilt the fixed box 8, then tighten the locking screw 10 to lock the tilt angle of the fixed box 8, and then realize the single locking wheel 11 or the deceleration belt 13 to contact with the belt.
