Description

Technical Field

[0001] This utility model belongs to the field of lifting equipment technology, specifically relating to a stabilizer for crane lifting. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. Also known as an overhead crane, gantry crane, or hoist, some lifting equipment operates intermittently, meaning that the corresponding mechanisms for material handling, transport, and unloading alternate within a work cycle. Cranes are becoming increasingly widespread in the market.

[0003] Sometimes, due to variations in the lifting conditions of the load at the bottom, lifting equipment may sway during the subsequent lifting process. This can sometimes affect nearby workers, thus requiring improvements to address the swaying issue. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a stabilizer for crane lifting.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a stabilizer for crane lifting, comprising two opposing side frames and a crossbeam connected to the top of the two side frames, an electric trolley slidably disposed below the crossbeam, an electric hoist disposed below the electric trolley, a controller extending downward from the bottom of the electric hoist, and a hook installed on the chain at the output end of the electric hoist, characterized in that: a stabilizer is installed between the two side frames, the stabilizer extends to the bottom of the hook, and the stabilizer is slidably disposed on both sides corresponding to the sides of the side frames.

[0006] Preferably, the stabilizer includes slide rails disposed on two sides of the side frame, with sliders slidably disposed on the slide rails, and limit pins at both ends of the slide rails.

[0007] Preferably, a lead screw is threaded into the top of the slider, and a limit block is fixedly connected to the top of the lead screw. A side plate is inserted between the two lead screws on the same side of the two side frames, and the two ends of the side plate are respectively provided with slots for inserting into the surface of the lead screw.

[0008] Preferably, each of the two opposing side plates is slidably provided with a sliding sleeve, and a pulley is rotatably inserted into the top and bottom of the sliding sleeve. The pulley is slidably provided with the side plate, and a sleeve is provided at the top and bottom of the two sliding sleeves facing each other. A limiting ring is inserted between the four sleeves, and a limiting hoop is fitted on both sides of the limiting ring.

[0009] The beneficial effects of this utility model are as follows: By setting slide rails on the front and rear sides of the side frame, and connecting the slide plates to the sliders on the slide rails via screw rods, the side plates can slide up and down on the slide rails in conjunction with the sliders. When the corresponding goods are lifted, the side plates move up and down with the sliders, thus providing better stability. At the same time, the sliding sleeves on the side plates, together with the pulleys set above and below the sliding sleeves, allow the pulleys to slide better left and right on the side plates. In addition, the sleeves are connected by a limit ring made of elastic rubber material, which can limit the side of the lifted goods. The limit rings are also fixed on the front and rear sides with the limit rings, making the goods more stable when being lifted up and down. Attached Figure Description

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] Example: A stabilizer for crane lifting, such as Figures 1-3 As shown, it includes two opposing side frames 1 and a crossbeam 11 connected to the top of the two side frames 1. An electric trolley 12 is slidably arranged below the crossbeam 11, and an electric hoist 13 is arranged below the electric trolley 12. A controller 15 is arranged downwardly at the bottom of the electric hoist 13, and a hook 14 is installed on the chain at the output end of the electric hoist 13. The feature is that a stabilizer is installed between the two side frames 1, the stabilizer extends to the bottom of the hook, and the two sides of the stabilizer are slidably arranged on the sides of the side frames 1.

[0016] The stabilizer includes slide rails 21 on two sides of the side frame 1. A slider 22 is slidably mounted on the slide rail 21, and each end of the slide rail 21 has a limit pin. A lead screw 23 is threaded into the top of the slider 22, and a limit block 24 is fixedly connected to the top of the lead screw 23. A side plate 25 is inserted between the two lead screws 23 on the same side of the two side frames 1. The two ends of the side plate 25 are respectively provided with slots 26 corresponding to the surface of the lead screw 23. Sliding sleeves 27 are slidably mounted on the two side plates 25 facing each other. A pulley 28 is rotatably inserted into the top and bottom of the sliding sleeve 27. The pulley 28 is slidably mounted corresponding to the side plate 25. A sleeve 29 is provided on the top and bottom of the two sliding sleeves 27 facing each other. A limit ring 210 is inserted between the four sleeves 29. Limiting hoops 211 are respectively fitted on the two sides of the limit ring 210.

[0017] The principle of this utility model is as follows: When lifting goods using the hook 14, the sliding sleeves 27 on both sides move according to the lateral size of the goods, driving the limiting rings 210 to both sides of the goods. After the limiting rings 210 are fitted onto both sides of the goods, the goods are clamped, preventing them from shaking freely. However, at this time, the limiting clamps 211 located on the limiting rings 210 need to be moved. The limiting clamps 211 can clamp the front and rear sides of the goods, working together with the limiting rings 210 to clamp the entire length of the goods. After clamping is completed, the limiting block 24 is rotated and inserted into the slider 22 through the lead screw 23. After the limiting block 24 clamps the inserted side plate 25, the stability of the goods movement is increased by the movement of the sliding rails 21 on both sides and the side plate 25 during lifting or transportation.

[0018] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
