DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1-3 , the present invention provides a fixed screw compressor lifting device for a zirconium sponge production workshop, including a support 1. A hinge seat 3 is fixedly assembled on the side end of the support 1. Swing rods 4 are rotatably assembled on both the upper and lower sides of the hinge seat 3. A protection structure 5 is assembled between the two swing rods 4. A main rod 6 is fixedly assembled on the upper end of the support 1. A suspension rod 9 is fixedly assembled on the upper end of the main rod 6. A winch 10 is fixedly assembled on one side of the surface of the suspension rod 9. A sling 11 is wound around the outer wall of the winch 10. A roller 12 is rotatably assembled on the inner wall of the other side of the suspension rod 9. The outer end of the sling 11 is attached to the roller 12 and a hook 13 is fixedly assembled. A pulley 2 is fixedly assembled at the lower end of the support 1. Two pulleys 2 are fixedly assembled at the lower end of each swing rod 4. The pulley 2 is a universal wheel.

[0016] The main components are connected together through the support 1 and cooperate with the pulley 2 to facilitate the movement of the equipment. At the same time, the pulley 2 is arranged at the lower end of the swing rod 4, which also facilitates the movement of the equipment. Through the cooperation of the hinge seat 3 and the swing rod 4, the included angle of the two swing rods 4 on both sides can be adjusted, so as to adjust whether the protection structure 5 works. When lifting the screw compressor, the angles of the two swing rods 4 on both sides need to be adjusted to close to 90 degrees to ensure sufficient lifting space. After the lifting is completed, the two swing rods 4 are adjusted to the state as shown in Figure 2 , and the protection structure 5 is connected. Through the action of the protection structure 5, during the transportation of the screw compressor, the screw compressor is prevented from falling and being damaged, playing a role in protecting the screw compressor. Through the cooperation of the main rod 6 and the suspension rod 9, a main frame for lifting is formed, and through the cooperation of the winch 10, the sling 11 and the hook 13, it is convenient to lift the screw compressor. At the same time, the winch 10 is arranged far away from the hook 13 at one time, which can effectively offset the gravity generated during lifting, ensuring the use effect and service life of the suspension rod 9. The roller 12 can effectively prevent the sling 11 from being worn, and has strong practicability.

[0017] The protection structure 5 includes two buffer plates 51. Both buffer plates 51 are fixedly assembled on the side walls of the corresponding swing rods 4. A metal plate 52 is fixedly assembled on the outer end of one of the buffer plates 51. An electromagnet 53 is fixedly assembled on the outer end of the other buffer plate 51. The electromagnet 53 is adsorbed to the metal plate 52.

[0018] When the buffer plates 51 on both sides are attached together, the electromagnet 53 is turned on to firmly adsorb the metal plate 52 on its side wall, ensuring the effect of the two buffer plates 51 being attached. The buffer plate 51 can be made of materials such as hard foam.

[0019] It also includes a buffer structure 7. The buffer structure 7 penetrates through the main rod 6 and the suspension rod 9, and the buffer structure 7 is connected to the sling 11.

[0020] The buffer structure 7 includes a slide rod 72. The slide rod 72 is assembled through the inner wall of the main rod 6. A top plate 71 is fixedly assembled at the outer end of the slide rod 72. A spring 73 is sleeved on the outer wall of the slide rod 72, and the spring 73 is located between the top plate 71 and the main rod 6. A steel rope 74 is fixedly assembled on the inner wall of the slide rod 72. The end of the steel rope 74 penetrates through the main rod 1 and the suspension rod 9 and is connected to a reel 77. The reel 77 is sleeved on the outer wall of the sling 11. A support wheel 75 is fixedly assembled on the side wall of the main rod 6. The steel rope 74 is attached to the outer side wall of the support wheel 75.

[0021] When the winch 11 is damaged during the hoisting and moving process, due to the gravitational force, the sling 11 will displace extremely rapidly. At this time, the reel 77 will immediately clamp the sling 11, and the support rod 76 will fix the position of the reel 77, and the sling 11 will also be fixed, which plays a role in protecting the hoisted screw compressor. At the same time, when the support rod 76 is damaged, the reel 77 will drive the steel rope 74 to displace a certain distance. At this time, the steel rope 74 will drive the slide rod 72 to displace along the inner wall of the main rod 6 and drive the top plate 71 to squeeze the spring 72 to achieve a certain buffering effect, protecting the steel rope 74 and fixing the steel cable 11 at the same time, also playing a role in protecting the hoisted screw compressor. The dual protection has a better effect.

[0022] A counterweight block 8 is fixedly assembled on the outer wall of the sling 11 on the side close to the hook 13.

[0023] The counterweight block 8 facilitates the falling of the hook 13.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
