Description
Technical Field
[0001] The utility model relates to the technical field of lifting devices, in particular to a safety lifting and traction device for a lift pump. Background Art
[0002] With the development of industry, the amount of industrial sewage is increasing, so various sewage treatment devices have emerged, and the sewage lift pump is one of them. Since the sewage contains a large amount of silt and impurities, the sewage lift pump needs to be taken out for maintenance every once in a while.
[0003] In the actual application process, taking the following sewage pool as an example: the pool depth is 12 meters, the pump opening is rectangular, 3 meters long and 2.3 meters wide, and the lift pump weighs 3 tons. Every time the lift pump is lifted, the personnel operate on the pool surface cover plate, tightening and loosening the shackle and the steel wire rope. And due to the height limit of the crane (usually only five or six meters high), it is necessary to borrow force twice or multiple times with the help of a chain to lift it up by the crane. This operation has great potential safety hazards. Content of the Utility Model
[0004] The purpose of the utility model is to provide a safety lifting and traction device for a lift pump. The utility model can lift the lift pump at one time and has the advantage of higher operation safety.

The crane is movably arranged on the track beam along the extending direction of the track beam. A hook is provided at the tension end of the crane. A lifting hook is provided on the lift pump. The traction rope passes through the lifting hook, and one end of the traction rope is connected to the hook, and the other end of the traction rope is connected to the power source of tension; it also includes a guide rail vertically arranged in the sewage pool. The lift pump is connected with a pump coupler, and the pump coupler is vertically slidably arranged on the guide rail; the traction rope is fixedly connected to the tip of the hook; at least one fixing ring is provided on the hook, and one of the fixing rings is arranged at the tip of the hook. A steel wire rope is threaded through the fixing ring, and the steel wire rope is wound around the outer periphery of the traction rope to fix the traction rope on the hook.
[0006] By adopting the above technical solution, the stainless steel chain is removed from this structure, and the operator does not need to stand on the suspended surface of the sewage tank for operation. It uses a traction rope to pass through the hook of the lift pump in advance. The two ends of the traction rope are respectively connected to the hook of the crane and a remote tension source.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment: As shown in the attached Figures 1 to 5 A lifting pump safety lifting and towing device for lifting the lift pump 1 in a sewage tank; it includes a rail beam 2, a crane 3, a towing rope 4 and a pulling force source 5. The crane 3 is movably arranged on the rail beam 2 along the extending direction of the rail beam 2. The crane 3 is a commercially available mass-produced part, and its specific structure will not be described in detail here. A hook 6 is provided at the pulling force end of the crane 3. The hook 6 is in the shape of a C shape or a J shape or a U shape. A suspension hook 7 is provided on the lift pump 1. The towing rope 4 can be made of nylon material or polyethylene fiber material with better strength, etc. The towing rope 4 passes through the suspension hook 7, and one end of the towing rope 4 is connected to the hook 6, and the other end of the towing rope 4 is connected to the pulling force source 5. This structure removes the stainless steel chain, and the operator does not need to stand on the suspended surface of the sewage tank for operation. It uses the towing rope 4 to pass through the suspension hook 7 of the lift pump 1 in advance. The two ends of the towing rope 4 are respectively connected to the hook 6 of the crane 3 and the pulling force source 5 in the distance. When it is necessary to lift the lift pump 1, the crane 3 lowers while the pulling force source 5 tightens the rope until the suspension hook 7 on the lift pump 1 slides along the towing rope 4 to the hook 6 of the crane 3, and the position can be found 100%. The crane 3 can lift the lift pump 1 onto the shore at one time without secondary relay, and has the advantage of higher operation safety.
[0023] As shown in the attached Figure 1 and attached Figure 3 As shown, the towing rope 4 is fixedly connected to the hook tip 8 of the hook 6. With this setting, the pulling force source 5 can pull the towing rope 4, prompting the suspension hook 7 on the lift pump 1 to slide along the towing rope 4 and finally accurately slide to the hook 6 of the crane 3, achieving 100% accurate positioning. It is not only more simple and convenient to operate, but also has higher safety.
[0024] As shown in the attached Figure 3As shown, at least one fixing ring 9 is provided on the hook 6, and one of the fixing rings 9 is arranged at the hook tip 8 of the hook 6. A steel wire rope 10 is threaded through the fixing ring 9, and the steel wire rope 10 is wound around the outer periphery of the towing rope 4 to fix the towing rope 4 on the hook 6. The connection between the towing rope 4 and the hook 6 can be realized, the connection operation is simple, and the connection structure is very firm. In addition, in this embodiment, two fixing rings 9 are adopted, and both of the two fixing rings 9 bind the towing rope 4 through the steel wire rope 10, thereby significantly improving the firmness of the connection between the towing rope 4 and the hook 6.
[0025] Among them, the fixing ring 9 is welded to the hook 6. The fixing ring 9 is arranged on the hook 6 by welding. This not only facilitates processing but also has a very firm connection and can withstand greater stress.
[0026] More specifically, in this embodiment, the fixing ring 9 is a hexagonal nut. The hexagonal nut is a common fastener. Using it as the fixing ring 9, one reason is that this component is easy to obtain and has a low cost. The other reason is that one side of the hexagonal nut is welded to the side of the hook 6 through solder, and the welding surface has a large contact area and the connection is also very firm.
[0027] As shown in the appendix Figure 4 As shown, the lifting hook 7 is arranged on the top of the lift pump 1, and the lifting hook 7 is in an inverted V shape. The structure of the inverted V-shaped lifting hook 7 can automatically adjust itself to the middle position when the towing rope 4 and the hook 6 cooperate, ensuring the stability of the lift pump 1 during movement. In addition, the lifting hook 7 can also be set in the shape of an inverted U.
[0028] Among them, both ends of the lifting hook 7 are connected to both sides of the top end of the lift pump 1 through bolts respectively. Its connection structure is simple and reliable, which is conducive to modification and processing. The use of bolts mainly takes into account the characteristics of easy disassembly and assembly. If the later disassembly and replacement are not considered, the two can also be connected by welding.
[0029] In addition, the pulling force source 5 is human power or a rope winch, and the rope winch is also a common commercially available product. By pulling the towing rope 4 remotely through human power or a rope winch, the lift pump 1 can be towed to the hook 6 of the crane 3, as shown in the appendix Figure 5 As shown, in this scheme, the pulling force source 5 adopted is a rope winch.
[0030] As shown in the appendix Figure 1 As shown, the device further includes a guide rail 11 vertically arranged in the sewage tank. The lift pump 1 is connected with a pump coupler 12, and the pump coupler 12 is slidably arranged on the guide rail 11 in the vertical direction. More specifically, the pump coupler 12 has a guide groove or a guide hole that cooperates with the guide rail 11. This design enables the lift pump 1 to be stably lifted or lowered along the guide rail 11.
