Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a hoisting device. Background Technology

[0002] In the field of metal processing, square tubes are a common structural material widely used in construction, machinery manufacturing and industrial pipelines. Before cutting and processing them, efficient hoisting and loading technology is a key link, which directly affects production efficiency and cutting accuracy. This link requires the use of hoisting equipment.

[0003] Chinese Patent Publication No. CN223385778U discloses a hoisting device, including a main housing. Two limiting grooves are formed on the inner surface of the main housing. A top shell is movably embedded in the inner surface of the main housing. Two limiting strips are fixedly connected to the outer surface of the top shell, and the outer surfaces of the limiting strips are movably embedded in the limiting grooves. A liner is fixedly connected to the inner surface of the main housing. A threaded rod is rotatably connected inside the liner. An internal threaded block is threadedly connected to the outer surface of the threaded rod. Fixing plates are fixedly connected to both sides of the internal threaded block. This invention features an upper and lower support structure, forming a stable support system that effectively disperses forces, preventing the equipment from tipping or shaking during operation. It fixes the equipment in a relatively stable space, allowing for smooth hoisting operations. It has high load-bearing capacity and will not be damaged due to excessive localized stress.

[0004] The aforementioned equipment improves its own stability. However, existing equipment relies solely on rotation to change the hoisting position of the square tube, which causes the square tube to swing significantly. At the same time, the hoisting range is limited, and the square tube cannot be quickly grabbed. Therefore, a hoisting device is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device to solve the problems of large swing of square tubes caused by the limited hoisting range of existing equipment and the difficulty in grabbing square tubes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device, including a hoisting motor, a hoisting rope fixedly installed on the output end of the hoisting motor, and a sliding mechanism provided on the hoisting motor; the sliding mechanism includes a gantry frame, a transverse motor fixedly installed at one end of the gantry frame, a first threaded shaft fixedly installed at the output end of the transverse motor, a first slide block threadedly installed on the first threaded shaft, an extension rod rotatably installed on the first slide block, a longitudinal motor fixedly installed at one end of the extension rod, a second threaded shaft fixedly installed at the output end of the longitudinal motor, and a second slide block threadedly installed on the second threaded shaft.

[0007] Preferably, the first threaded shaft is rotatably mounted on the gantry frame, and the second threaded shaft is rotatably mounted on the extension rod.

[0008] Preferably, the first slide block is slidably mounted on the gantry frame, and the second slide block is slidably mounted on the extension rod.

[0009] Preferably, the bottom of the extension rod is rotatably mounted on the first slide block by two discs with different inner diameters, and the longitudinal movement motor is fixedly mounted on the second slide block.

[0010] Preferably, a gripping mechanism is fixedly installed at one end of the hoisting rope. The gripping mechanism includes a frame, which is fixedly installed on the hoisting rope. A first hook and a second hook are rotatably installed on the frame. A buckle is rotatably installed through both the first hook and the second hook, and an electric telescopic rod is fixedly installed between the two buckles.

[0011] Preferably, the first grab hook and the second grab hook are rotatably connected in an alternating manner, and the two latches are respectively rotatably installed at the front end positions of the first grab hook and the second grab hook.

[0012] Preferably, the two buckles are fixedly connected to the output end of the electric telescopic rod and the outer casing respectively, and two spherical protrusions are arranged side by side on the hanger.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The hoisting equipment controls the horizontal and vertical motors to rotate the No. 1 and No. 2 threaded shafts, which in turn drive the No. 1 and No. 2 slide blocks to reciprocate on the gantry and extension rods, respectively. This further enables the hoisting motors to move horizontally or vertically smoothly. This movement method can ensure the relative stability of the square tube during hoisting.

[0014] 2) This hoisting equipment benefits from the connection between the No. 1 grab hook and the No. 2 grab hook. The two ends of the electric telescopic rod are rotatably connected to the No. 1 grab hook and the No. 2 grab hook through the buckle. When in use, the electric telescopic rod is extended or shortened as a whole, thereby realizing the quick grabbing or release of the No. 1 grab hook on the pipe. Compared with the traditional sleeve-type fixing of the pipe, this method is more flexible and stable. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Combination Figures 1-4 A hoisting device includes a hoisting motor 1, a hoisting rope 2 fixedly installed on the output end of the hoisting motor 1, and a sliding mechanism 3 provided on the hoisting motor 1; the sliding mechanism 3 includes a gantry frame 301, a transverse motor 302 fixedly installed on one end of the gantry frame 301, a first threaded shaft 303 fixedly installed on the output end of the transverse motor 302, a first slide block 304 threadedly installed on the first threaded shaft 303, an extension rod 305 rotatably installed on the first slide block 304, a longitudinal motor 306 fixedly installed on one end of the extension rod 305, a second threaded shaft 307 fixedly installed on the output end of the longitudinal motor 306, and a second slide block 308 threadedly installed on the second threaded shaft 307.

[0019] The first threaded shaft 303 is rotatably mounted on the gantry 301, the second threaded shaft 307 is rotatably mounted on the extension rod 305, the first slide block 304 is slidably mounted on the gantry 301, and the second slide block 308 is slidably mounted on the extension rod 305. Driven by the first threaded shaft 303 and the second threaded shaft 307 respectively, the first slide block 304 and the second slide block 308 reciprocate on the gantry 301 and the extension rod 305, further enabling the hoisting motor 1 to move laterally or longitudinally. This movement method ensures the relative stability of the square tube during hoisting. The bottom of the extension rod 305 is rotatably mounted on the first slide block 304 via two discs of different inner diameters, allowing the extension rod 305 to retain its rotational function and adapt to small-amplitude turning. The longitudinal movement motor 306 is fixedly mounted on the second slide block 308.

[0020] Example 2 See Figure 5 A gripping mechanism 4 is fixedly installed at one end of the suspension rope 2. The gripping mechanism 4 includes a frame 401, which is fixedly installed on the suspension rope 2. A first gripping hook 402 and a second gripping hook 403 are rotatably installed on the frame 401. A buckle 404 is rotatably installed through both the first gripping hook 402 and the second gripping hook 403. An electric telescopic rod 405 is fixedly installed between the two buckles 404.

[0021] The first hook 402 and the second hook 403 are rotated and interleaved, allowing the square tube to be gathered and clamped between the first hook 402 and the second hook 403. Two latches 404 are rotatably installed at the front end of the first hook 402 and the second hook 403, respectively. The two latches 404 are fixedly connected to the output end of the electric telescopic rod 405 and the outer shell, respectively. By controlling the extension or retraction of the electric telescopic rod 405 as a whole, the first hook 402 can grasp or release the square tube. Two spherical protrusions are arranged side by side on the hanger 401 to facilitate the movement of the hanger 401.

[0022] In actual operation, the horizontal movement motor 302 and the vertical movement motor 306 are controlled to rotate the first threaded shaft 303 and the second threaded shaft 307, so that the first slide block 304 and the second slide block 308 are driven by the first threaded shaft 303 and the second threaded shaft 307 respectively to reciprocate on the gantry frame 301 and the extension rod 305, and further cause the hoisting motor 1 to move horizontally or vertically. This movement method can ensure the relative stability of the square tube during hoisting. Benefiting from the connection between the first grab hook 402 and the second grab hook 403, and with both ends of the electric telescopic rod 405 rotatably connected to the first grab hook 402 and the second grab hook 403 via the buckle 404, the electric telescopic rod 405 can be extended or shortened as a whole during use, thereby enabling the first grab hook 402 to quickly grab or release the square tube. Compared with the traditional sleeve-type fixing of the square tube, this method will better ensure the flexible grabbing and stability of the square tube.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
