Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment products, and particularly relates to an anti-reversal single support wheel. Background Art

[0002] The supporting wheel is an important component of the supporting device. It connects the rope and supports the weight of the rotating part of the rope. It also plays a directional role on the rope. The single supporting wheel is a single load-bearing supporting wheel, and the supporting wheel has the characteristic of changing the force. It is used in many fields such as machinery, electromechanics, engineering construction, etc., and its use is very wide.

[0003] Nowadays, the supporting wheels on the market can rotate in both directions. In some cases, after the applied force disappears (such as the breakage of the steel cable, etc.), the pulled object on the other side of the supporting wheel will quickly reverse along the original route, which can easily lead to safety accidents and cause loss of life and property of the workers. In addition, the wheel lining will be worn after long-term use, and the friction between the supporting wheel and the supporting wheel will be reduced, which may cause slippage and affect the normal operation of the supporting wheel. In order to solve the above problems, an anti-reversal single supporting wheel is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the supporting wheels on the market nowadays can rotate in both directions, but in some cases, after the applied force disappears (such as the breakage of the steel cable, etc.), the pulled object on the other side of the supporting wheel will quickly reverse along the original route, which is likely to cause safety accidents and cause losses to the lives and property of the workers. In addition, the wheel lining will be worn after long-term use, and the friction between the supporting wheel and the supporting wheel will be reduced, which may cause slippage and affect the normal operation of the supporting wheel. Therefore, an anti-reversal single supporting wheel is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-reversal single support wheel, comprising a threaded rod, a fixing rod is fixedly installed at one end of the threaded rod, a nut is fixedly installed on the outer wall of the threaded rod, one end of the fixing rod is rotatably connected to a rotating rod, an anti-reversal component is arranged on the outside of the rotating rod, a support wheel is fixedly installed at one end of the rotating rod, a wheel liner is arranged on the outside of the support wheel, and a fixed positioning component is arranged at one end of the support wheel.

[0006] As a further description of the above technical solution:

[0007] The fixing and positioning assembly comprises bolts, the supporting wheel is threadedly connected with the bolts through a threaded hole arranged inside the supporting wheel, and the wheel liner is slidably connected with a protrusion through a groove arranged inside the wheel liner.

[0008] As a further description of the above technical solution:

[0009] A fixing plate is fixedly mounted on one side surface of the protrusion, the supporting wheel is fixedly mounted on the fixing plate via bolts, and a bearing housing is fixedly mounted on the outer wall of the fixing rod.

[0010] As a further description of the above technical solution:

[0011] The anti-reversal component comprises a ratchet, the ratchet is fixedly mounted on the outer wall of the rotating rod, and a fixing frame is fixedly mounted on one end of the bearing housing.

[0012] As a further description of the above technical solution:

[0013] A spring is fixedly connected to the top surface of the fixing frame, a pawl is fixedly installed on the top end of the spring, and one end of the bearing housing is rotatably connected to the pawl.

[0014] As a further description of the above technical solution:

[0015] A friction pad is fixedly mounted on the outside of the supporting wheel, and two fixed positioning components are symmetrically arranged about the longitudinal central symmetry axis of the supporting wheel.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, by providing a fixed positioning component and an anti-reversal component, when the device is used, during installation, the fixed plate is inserted into the groove in the wheel liner through the protrusion to perform positioning, and then the bolt is inserted to fix the fixed plate and the supporting wheel. During the fixing of the two fixed plates, the wheel liner is gradually clamped, and it is convenient to disassemble. Then, the supporting wheel is fixed to the steel frame by rotating the nut. Under normal circumstances, the rotation of the supporting wheel drives the rotation of the rotating rod, and the rotation of the rotating rod drives the rotation of the ratchet wheel. The rotation of the ratchet wheel causes its teeth to squeeze the pawl, and the ratchet wheel is squeezed to cause the spring to The spring is compressed so that the ratchet can rotate normally. When the ratchet rotates in the opposite direction, the pawl will press the teeth on the outside of the ratchet to prevent reversal. Through this design, not only the function of preventing the wheel lining from slipping during use is achieved, but also the function of preventing the supporting wheel from reversing, thus avoiding safety accidents caused by the reversal of the supporting wheel, thereby causing loss of life and property of the workers. In addition, since the wheel lining will be worn after long-term use, the friction between the supporting wheel and the supporting wheel will be reduced, and slipping may occur, affecting the normal operation of the supporting wheel. In addition, it is simple and convenient to use and has strong practicality.

[0018] 2. In the utility model, by providing a friction pad, during the use of the device, since the wheel lining is mostly made of plastic, a certain amount of wear will occur during use. The provision of the friction pad can prevent the wire rope from directly contacting the supporting wheel, thereby causing the wire rope to break or break and the supporting wheel to be worn, affecting work efficiency and causing loss of life and property. The utility model is simple and convenient to use and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The fixed positioning assembly 2 includes a bolt 23, the supporting wheel 6 is threadedly connected with the bolt 23 through a threaded hole provided therein, the wheel liner 1 is slidably connected with a protrusion 21 through a groove provided therein, a fixed plate 22 is fixedly installed on one side surface of the protrusion 21, the supporting wheel 6 is fixedly installed with the fixed plate 22 through the bolt 23, a bearing housing 24 is fixedly installed on the outer wall of the fixing rod 3, the anti-reversal assembly 9 includes a ratchet 93, a ratchet 93 is fixedly installed on the outer wall of the rotating rod 8, a fixing frame 92 is fixedly installed on one end of the bearing housing 24, a spring 91 is fixedly connected to the top surface of the fixing frame 92, a ratchet 94 is fixedly installed on the top of the spring 91, and a ratchet 94 is rotatably connected to one end of the bearing housing 24;

[0028] The specific implementation method is as follows: when the device is used, during installation, the fixing plate 22 is inserted into the groove in the wheel liner 1 through the protrusion 21 to position it, and then the bolt 23 is turned to fix the fixing plate 22 and the supporting wheel 6. During the fixing of the two fixing plates 22, the wheel liner 1 will be gradually clamped, and it is convenient to disassemble. Then, the supporting wheel 6 is fixed to the steel frame by rotating the nut 4. Under normal circumstances, the rotation of the supporting wheel 6 drives the rotation of the rotating rod 8, and the rotation of the rotating rod 8 drives the rotation of the ratchet 93. The rotation of the ratchet 93 causes its teeth to squeeze the pawl 94. After the ratchet 93 is squeezed, the spring 91 is compressed, so that the ratchet 93 can rotate normally. When the ratchet 93 rotates in the opposite direction, the pawl 94 will press the teeth outside the ratchet 93 to prevent reversal.

[0029] A friction pad 7 is fixedly mounted on the outside of the supporting wheel 6 , and two fixed positioning components 2 are symmetrically arranged about the longitudinal central symmetry axis of the supporting wheel 6 .

[0030] The specific implementation method is as follows: during the use of the device, since the wheel lining 1 is mostly made of plastic, it will produce certain wear during use, and the setting of the friction pad 7 can prevent the steel wire rope from directly contacting the supporting wheel 6, thereby causing the steel wire rope to break or break and the supporting wheel 6 to be worn, affecting work efficiency and causing loss of life and property.

[0031] Working principle: When the device is used, during installation, the fixing plate 22 is inserted into the groove in the wheel liner 1 through the protrusion 21 to position it, and then the bolt 23 is turned to fix the fixing plate 22 and the supporting wheel 6. During the fixing of the two fixing plates 22, the wheel liner 1 will be gradually clamped, and it is convenient to disassemble. Then, the supporting wheel 6 is fixed to the steel frame by rotating the nut 4. Under normal circumstances, the rotation of the supporting wheel 6 drives the rotation of the rotating rod 8, and the rotation of the rotating rod 8 drives the rotation of the ratchet 93. The rotation of the ratchet 93 causes its teeth to engage with the ratchet. The pawl 94 is squeezed, and the spring 91 is compressed after the ratchet 93 is squeezed, so that the ratchet 93 can rotate normally. When the ratchet 93 rotates in the opposite direction, the pawl 94 will press the teeth on the outside of the ratchet 93 to prevent reversal. During the use of the device, since the wheel liner 1 is mostly made of plastic, it will produce a certain amount of wear during use. The setting of the friction pad 7 can prevent the wire rope from directly contacting the supporting wheel 6, which will cause the wire rope to break or break and the supporting wheel 6 to wear, affecting the work efficiency and causing loss of life and property.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
