Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of belt dismounting, in particular to a flexible belt dismounting device. BACKGROUND

[0002] Since the belt has the advantages of stable transmission operation, low noise, small vibration, simple structure, convenient adjustment and the like, it is used to transmit power in many machining occasions. The fan belt needs to be repaired or replaced due to wear after being used for a period of time. At present, since there is a lack of a special tool for dismounting the fan belt, most of the replacement is dependent on manual operation by the operator. When the operator dismounts the belt manually, one hand is generally used to rotate the belt pulley and the other hand is used to pull the belt, which is time-consuming and laborious, and the belt pulley may uncontrollably rotate under the action of the belt during the pulling process, thereby causing the operator's hand to be clamped between the belt and the belt pulley, resulting in safety accidents such as hand injury or permanent hand injury.

[0003] Although there are some belt dismounting tools in the prior art, the existing belt dismounting tools can only dismount a belt of a certain fixed size or model, and different specifications of belt dismounting tools need to be designed to dismount different belts, which results in a large variety of belt dismounting tools, poor universality and high use cost. Therefore, it is urgent to develop a tool capable of quickly dismounting belts of different sizes or models to improve the belt dismounting efficiency and avoid the occurrence of belt clamping accidents. SUMMARY

[0004] The present application provides a flexible belt dismounting device to solve the problems of time-consuming and laborious belt dismounting and easy occurrence of work injury accidents in the prior art.

When the size of the installation slot is less than R65mm, the dismounting device is not suitable for the dismounting requirement of the belt on the commonly used belt pulley in the workshop. When the size of the installation slot is greater than R180mm, the overall volume and weight of the dismounting device are relatively large, which is inconvenient for maintenance personnel to install the device on the belt pulley. At the same time, the length of the installation slot ranges from R65mm to R180mm, which can meet the dismounting requirement of the belt on the belt pulley in the workshop.

[0010] Further, three circumferentially distributed rib plates are arranged between the outer rim and the inner rim, and a fourth rib plate is further arranged between two adjacent rib plates.

[0011] The beneficial effects of the above further technical solutions are that the dismounting device can be fixed on belt pulleys of different sizes by arranging four rib plates, so as to meet the dismounting requirement of the belt.

[0012] Further, a plurality of evenly distributed accommodating holes are arranged on the outer rim, and the operating rod is detachably installed in the accommodating hole.

[0013] The beneficial effects of the above further technical solutions are that one or more operating rods can be installed according to the size of the belt pulley, so as to exert a large enough force to rotate the belt pulley, so that the belt can be smoothly dismounted.

[0014] Further, a bandage is further included, and the bandage is used to bind the belt.

[0015] The beneficial effects of the above further technical solutions are that the hands of the maintenance personnel are prevented from contacting the belt, extrusion is avoided, and the safety during maintenance is improved.

[0016] Further, the tension plate and the tension rod are in L shape.

[0017] The beneficial effects of the above further technical solutions are that the dismounting device can be conveniently fixed on the rib plate of the fan belt pulley, so that the belt pulley can be smoothly rotated.

[0018] Further, the inner rim is arranged with a shaft sleeve, the inner wall of the shaft sleeve is arranged with a key groove, the outer wall of the shaft sleeve is arranged with a groove, the inner rim is arranged with a fixing hole corresponding to the groove, and the fixing hole is used for accommodating a jackscrew.

[0019] The beneficial effect of the further technical scheme is that the key groove is fixed with the main shaft of the fan, and the shaft sleeve and the inner rim are fixed together through the cooperation of the groove, the fixing hole and the jackscrew, so that the belt wheel is driven to rotate when the runner body rotates, thereby the belt is disassembled from the belt wheel, the overall connection is simple, the disassembly is convenient, the hands of the maintenance personnel are prevented from contacting the meshing pressure point of the belt wheel, and the safety risk is reduced.

[0020] Further, the side wall of the shaft sleeve is arranged with a positioning hole, and the positioning hole is arranged with a positioning piece.

[0021] The beneficial effect of the further technical scheme is that the shaft sleeve is preliminarily fixed on the output shaft of the belt wheel through the positioning piece, so that the runner body is more convenient to install, and the firmness of the shaft sleeve is ensured through cooperation with the key groove, thereby preventing the shaft sleeve from rotating on the output shaft of the belt wheel.

[0022] Further, the groove is arranged with three, the three grooves are circumferentially distributed on the outer side wall of the shaft sleeve, and the groove extends along the length direction of the shaft sleeve.

[0023] The beneficial effect of the further technical scheme is that the firmness of the shaft sleeve is ensured, and the position of the shaft sleeve is adjusted, thereby reducing the difficulty of installation.

[0024] Further, the prying rod comprises a rod body and a prying rod and a supporting rod arranged at the end of the rod body, the prying rod is perpendicular to the rod body, and the supporting rod is arranged at an angle with the rod body.

[0025] The beneficial effect of the further technical scheme is that when the belt is installed, the belt can be smoothly installed in the belt wheel through the prying rod, the hands of the maintenance personnel are prevented from directly installing, and the safety of installing the belt is improved.
