Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a tension regulating device for an elevator belt. Background Art

[0002] Hoists are large-scale mechanical equipment that transports by changing potential energy, such as mine hoists and dam hoists; in a broad sense, elevators, overhead cranes, winches, stabilizers, cranes, hoists, etc. can all be called hoists; hoists generally refer to large-scale mechanical equipment with high power and strong lifting capacity. Due to the wide range of uses of hoists, it is also necessary to optimize the structure of the hoists.

[0003] For example, a Chinese utility model patent with announcement number CN219651986U discloses an elevator. Although the above-mentioned prior art can solve the problem that after the elevator belt is offset, it needs to be manually adjusted repeatedly, which is labor-intensive and time-consuming, but when the elevator is in use, the belt will be pulled by the rotation of the motor shaft to allow the shaft of another elevator to rotate. Such pulling is not a problem in a short time, but it will cause the belt to loosen over time. After the belt is loose, it will not be able to fit tightly against the two shafts, which will cause problems in the transmission system of the elevator. Because the belt is not damaged and cannot be used, it will waste resources to replace it every time it is not damaged, and each replacement requires stopping the machine for employees to climb up and down, affecting work efficiency. Therefore, it is necessary to design a tension adjustment device for the elevator belt that can adjust the tension of the elevator belt after it is loose. Utility Model Content

[0004] In order to solve the technical problem that the elevator belt cannot be closely attached to the two shafts after being loosened, which causes problems in the transmission system, the utility model provides a tension adjustment device for the elevator belt.

[0005] The utility model is implemented by the following technical scheme: a tension adjustment device for an elevator belt, comprising an elevator body, a motor is provided on one side of the elevator body, a first rotating shaft is installed on the other side of the elevator body, a second rotating shaft is fixedly installed on the output end of the motor, a synchronous belt is sleeved on the first rotating shaft and the second rotating shaft, an adjustment component for adjusting the tension of the synchronous belt is provided on one side of the synchronous belt, a driving component for driving the adjustment component to move and control the tension of the synchronous belt is provided on one side of the driving component, and a fixing component for fixing the driving component is provided on one side of the driving component.

[0006] Through the above technical solution, after the synchronous belt of the elevator body is relaxed, the adjusting component can adjust the tension of the synchronous belt by rotating the driving component.

[0007] As a further improvement of the above-mentioned scheme, the adjustment assembly includes an adjustment plate arranged on one side of the synchronous belt and having a rotation groove, a rotating shaft rotatably installed inside the rotation groove, and a rotating column sleeved on the rotating shaft. The synchronous belt is used in conjunction with the rotation groove, and the outer surface of the rotating column is in contact with one side of the synchronous belt.

[0008] Through the above technical solution, when the adjustment plate moves downward, the rotating column will pull the synchronous belt, so the tension of the synchronous belt can be adjusted.

[0009] As a further improvement of the above scheme, the driving assembly includes a rack fixedly mounted on one side of the adjusting plate, a rotating rod rotatably mounted on one side of the elevator body, and a driving gear fixedly sleeved on the rotating rod and meshingly connected to the rack, and a pushing column is fixedly mounted on one side of the driving gear.

[0010] Through the above technical solution, the driving gear rotates, which causes the rack to pull the adjustment plate.

[0011] As a further improvement of the above scheme, the fixing assembly includes a fixing plate fixedly installed on one side of the lifting machine body, a locking block arranged on one side of the fixing plate and two limiting rods fixedly installed on one side of the locking block, one end of the two limiting rods passes through the fixing plate, and the two limiting rods are each provided with a pushing spring with one end fixedly installed on the locking block and the other end fixedly installed on the fixing plate, and the locking block is used in conjunction with the driving gear.

[0012] Through the above technical solution, the spring pushes the locking block so that the locking block can fix the driving gear.

[0013] As a further improvement of the above solution, the sliding sleeve on the adjustment plate is provided with a limiting sleeve with one side fixedly mounted to the elevator body, and a moving opening matched with the rack is opened on one side of the limiting sleeve.

[0014] Through the above technical solution, the limiting sleeve can prevent the adjustment plate from deviating.

[0015] As a further improvement of the above solution, a sliding groove is provided on one side of the elevator body, and a sliding block is slidably installed inside the sliding groove and one side of the sliding block is fixedly installed with the adjustment plate.

[0016] Through the above technical solution, the sliding block cooperates with the adjusting plate to prevent the adjusting plate from tilting during the movement.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides an adjusting component, a driving component and a fixing component. After the synchronous belt of the elevator body is loose due to insufficient tension, the fixing component is moved to release the fixing effect of the driving component, and the driving component is rotated to allow the adjusting component to move, so that the synchronous belt can be pulled and the loose synchronous belt can be straightened. This arrangement allows the synchronous belt to continue to be used when it is just loose due to insufficient tension but not damaged, avoiding waste caused by replacement and stopping the machine to affect work efficiency.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A tension adjustment device for an elevator belt in this embodiment includes an elevator body 1, a motor 2 is provided on one side of the elevator body 1, a first rotating shaft 3 is installed on the other side of the elevator body 1, a second rotating shaft 4 is fixedly installed on the output end of the motor 2, a synchronous belt 5 is sleeved on the first rotating shaft 3 and the second rotating shaft 4, an adjusting component for adjusting the tension of the synchronous belt 5 is provided on one side of the synchronous belt 5, a driving component for driving the adjusting component to move and control the tension of the synchronous belt 5 is provided on one side of the adjusting component, and a fixing component for fixing the driving component is provided on one side of the driving component.

[0027] Combination Figure 1 and Figure 2 The adjustment component includes an adjustment plate 601 which is arranged on one side of the synchronous belt 5 and has a rotation groove, a rotating shaft 602 rotatably installed inside the rotation groove, and a rotating column 603 sleeved on the rotating shaft 602. The synchronous belt 5 is used in conjunction with the rotation groove. The outer surface of the rotating column 603 fits with one side of the synchronous belt 5. When the adjustment plate 601 moves downward, the rotating column 603 will pull the synchronous belt 5, so that the tension of the synchronous belt 5 can be adjusted.

[0028] Combination Figure 2 and Figure 3 The driving assembly includes a rack 701 fixedly mounted on one side of the adjusting plate 601, a rotating rod 702 rotatably mounted on one side of the lifting machine body 1, and a driving gear 703 fixedly sleeved on the rotating rod 702 and meshingly connected with the rack 701. A pushing column 9 is fixedly mounted on one side of the driving gear 703. When the driving gear 703 rotates, the rack 701 will pull the adjusting plate 601.

[0029] Combination Figure 2 and Figure 3 The fixing assembly includes a fixing plate 801 fixedly installed on one side of the lifting machine body 1, a locking block 802 arranged on one side of the fixing plate 801 and two limiting rods 803 fixedly installed on one side of the locking block 802. One end of the two limiting rods 803 passes through the fixing plate 801. The two limiting rods 803 are both sleeved with a pushing spring 10 with one end fixedly installed on the locking block 802 and the other end fixedly installed on the fixing plate 801. The locking block 802 is used in conjunction with the driving gear 703. The pushing spring 10 pushes the locking block 802 so that the locking block 802 can fix the driving gear 703.

[0030] Combination Figure 1 , Figure 2 and Figure 4 A sliding sleeve on the adjustment plate 601 is provided with a limit sleeve 11 whose one side is fixedly mounted on the elevator body 1, and a moving opening matched with the rack 701 is opened on one side of the limit sleeve 11. A sliding groove is opened on one side of the elevator body 1, and a sliding block 12 whose one side is fixedly mounted on the adjustment plate 601 is slidably installed inside the sliding groove. The sliding block 12 cooperates with the adjustment plate 601 to prevent the adjustment plate 601 from tilting during the movement.

[0031] The implementation principle of a tension adjustment device for a hoist belt in the embodiment of the present application is as follows: when the synchronous belt 5 is loose due to insufficient tension, the locking block 802 is pulled to release the fixing effect on the driving gear 703, and then the driving gear 703 rotates, which will drive the rack 701 to move, and the rack 701 will pull the adjustment plate 601 to move together, so that the rotating column 603 inside the rotating groove will move downward, and during the downward movement of the rotating column 603, one side of the synchronous belt 5 will be pulled downward together, so that the original two points of the synchronous belt 5 become three points, and the synchronous belt 5 will be straightened again after being pulled. The rotating column 603 is a cylinder, so it will not affect the rotation of the synchronous belt 5. This arrangement allows the synchronous belt 5 to continue to be used when it is just loose due to insufficient tension but not damaged, avoiding waste caused by replacement and stopping the machine to affect work efficiency.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
