[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with 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 belong to the scope of protection of the present utility model.

[0018] The following gives specific embodiments.

[0019] Refer to Figures 1 to 5 , in the embodiment of the present utility model, an adjustable steel transportation and lifting device includes a base 1, a lifting mechanism 2, a lifting plate 3, an adjusting mechanism 4, and a clamping mechanism 5. The base 1 is fixed on the ground. The lifting mechanism 2 is installed on the base 1. The lower end of the lifting mechanism 2 is fixed with a lifting plate 3. The lower side of the lifting plate 3 is provided with an adjusting mechanism 4. The adjusting mechanism 4 includes: a second motor 401, a bidirectional screw 402, a first external thread 403, a second external thread 404, a first thread sleeve 405, a second thread sleeve 406, and a bracket 407. The second motor 401 is fixed on the lower side of the lifting plate 3. The bidirectional screw 402 is rotatably connected to the lower side of the lifting plate 3. The output shaft of the second motor 401 is connected to the bidirectional screw 402. The left half section of the bidirectional screw 402 is provided with a first external thread 403. The outside of the first external thread 403 is installed with a first thread sleeve 405 that matches it. The right half section of the bidirectional screw 402 is provided with a second external thread 404. The outside of the second external thread 404 is installed with a second thread sleeve 406 that matches it. A bracket 407 is fixed to the lower sides of both the first thread sleeve 405 and the second thread sleeve 406. Two slide rails 4072 are fixed to the lower side of the lifting plate 3. Two sliders 4071 are fixed to each bracket 407. The upper sliders 4071 are slidably installed on the slide rails 4072. A clamping mechanism 5 is installed on each bracket 407. The first external thread 403 and the second external thread 404 have opposite helix directions, so that when the bidirectional screw 402 rotates, the moving directions of the first thread sleeve 405 and the second thread sleeve 406 are opposite. When in use, the second motor 401 drives the bidirectional screw 402 to rotate. The rotation of the bidirectional screw 402 drives the first thread sleeve 405 and the second thread sleeve 406 to move towards each other. The first thread sleeve 405 and the second thread sleeve 406 drive the two clamping mechanisms 5 to move towards each other, thereby adjusting the distance between the two clamping mechanisms 5 to support steel materials of different lengths.

[0020] The lifting mechanism 2 includes: a first motor 201, a transmission shaft 202, a winding wheel 203, and a steel wire rope 204. The first motor 201 is fixed to the upper end of the base 1. The transmission shaft 202 is rotatably connected to the upper end of the base 1. The output shaft of the first motor 201 is connected to the transmission shaft 202. A winding wheel 203 is installed on the transmission shaft 202. A steel wire rope 204 is installed on the winding wheel 203. The lower end of the steel wire rope 204 is fixed to the lifting plate 3. When in use, the first motor 201 drives the transmission shaft 202 and the winding wheel 203 to rotate. The rotation of the winding wheel 203 drives the telescopic movement of the steel wire rope 204. The telescopic movement of the steel wire rope 204 drives the up and down movement of the lifting plate 3.

[0021] The clamping mechanism 5 includes: a hydraulic cylinder 501 and a pressing plate 502. The hydraulic cylinder 501 is fixed to the bracket 407. The output end of the hydraulic cylinder 501 is connected to the pressing plate 502. When in use, the hydraulic cylinder 501 drives the pressing plate 502 to press the steel material into the bracket 407.

[0022] Both the lifting plate 3 and the bracket 407 are made of aluminum alloy, making them have good strength and corrosion resistance.

[0023] Working principle: For this adjustable steel material transportation and lifting device, when in use, the second motor 401 drives the bidirectional screw 402 to rotate. The rotation of the bidirectional screw 402 drives the first thread sleeve 405 and the second thread sleeve 406 to move towards each other. The first thread sleeve 405 and the second thread sleeve 406 drive the two clamping mechanisms 5 to move towards each other, thereby adjusting the distance between the two clamping mechanisms 5 to support steel materials of different lengths. After adjustment, the steel material is inserted into the two brackets 407. Then, the hydraulic cylinder 501 drives the pressing plate 502 to press the steel material into the bracket 407 to improve the stability of the steel material. Finally, the first motor 201 drives the transmission shaft 202 and the winding wheel 203 to rotate. The rotation of the winding wheel 203 drives the contraction of the steel wire rope 204. The contraction of the steel wire rope 204 drives the lifting plate 3 to move upward, thereby lifting the steel material.
