Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic hoist auxiliary equipment, in particular to a cable guiding device of a pneumatic hoist. Background Art

[0002] Pneumatic hoist is a lifting equipment that uses air pressure as driving force. It is widely used in petroleum, chemical industry, coal mining, textile, warehousing, production lines, etc. It is mainly composed of air distribution system, power system, deceleration system and winch system.

[0003] During the use of pneumatic hoists, the hoisting system is the component for winding cables. During hoisting, the cables are stressed and always in a taut state. If they are directly wound up, they are easy to accumulate at the same position of the winding roller. Even after winding up, the cables are still taut, which can easily reduce the service life of the pneumatic hoist. Therefore, a cable guiding device is proposed to reduce the fatigue of the cables.

[0015] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to Figure 1-3 The utility model discloses a cable guiding device for a pneumatic hoist, comprising a mounting frame 1, wherein a first pneumatic winding wheel 2 and a second pneumatic winding wheel 3 are respectively arranged at two ends of the bottom of the mounting frame 1, wherein the first pneumatic winding wheel 2 and the second pneumatic winding wheel 3 are both pneumatically driven, and a movable guiding frame 8 is arranged at the lower middle part of the mounting frame 1, and the cable of the pneumatic hoist passes through the inside of the guiding frame 8.

[0019] A slide groove 4 is excavated in the middle of the mounting frame 1, and a guide slider 5 is slidably connected inside the slide groove 4. The bottom of the guide slider 5 is fixedly connected to the guide frame 8. A reciprocating screw rod 6 is rotatably connected between the two ends of the slide groove 4, and the reciprocating screw rod 6 is threadedly connected to the guide slider 5. A servo motor 7 is fixedly connected to one side of the mounting frame 1. The output end of the servo motor 7 passes through the mounting frame 1 and is threadedly connected to the reciprocating screw rod 6. Driven by the servo motor 7, the reciprocating screw rod 6 drives the guide slider 5 to reciprocate inside the slide groove 4, so that the guide frame 8 evenly arranges the cable on the No. 1 pneumatic winding wheel 2. Two extrusion plates 10 are provided inside the guide frame 8. A plurality of springs 9 are fixedly connected to the sides of the two extrusion plates 10 away from each other. The end of the spring 9 away from the extrusion plate 10 is fixedly connected to the guide frame 8. When the No. 1 pneumatic winding wheel 2 is wound, due to the extrusion of the two extrusion plates 10 inside the guide frame 8, the cable is prevented from being too loose and knotted when it is wrapped around the No. 1 pneumatic winding wheel 2.

[0020] Specifically, when the utility model is used, after fixing the end of the cable on the No. 1 pneumatic winding wheel 2, the cable is passed between the two extrusion plates 10 inside the guide frame 8, and the cable is wound around the outside of the No. 2 pneumatic winding wheel 3 for several turns, so that the cable between the No. 2 pneumatic winding wheel 3 and the guide frame 8 is in a drooping state. When the pneumatic hoist is used, the driving system of the No. 2 pneumatic winding wheel 3 and the No. 1 pneumatic winding wheel 2 is turned on to drive the two winding wheels to rotate, and the No. 2 pneumatic winding wheel 3 pulls up the cable that pulls the heavy object. The No. 1 pneumatic winding wheel 2 also rotates to wind up the cable pulled up by the No. 2 pneumatic winding wheel 3. When the No. 1 pneumatic winding wheel 2 is wound, the reciprocating screw rod 6 drives the guide slider 5 to move back and forth inside the slide groove 4 under the drive of the servo motor 7, so that the guide frame 8 evenly arranges the cable on the No. 1 pneumatic winding wheel 2. When the No. 1 pneumatic winding wheel 2 is wound, due to the squeezing of two squeezing plates 10 inside the guide frame 8, the cable is prevented from being too loose and knotted when it is wound around the No. 1 pneumatic winding wheel 2.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
