Description

Technical Field

[0001] The utility model relates to the technical field of steel materials, in particular to a steel material production hoisting device. Background Art

[0002] Steel is a material with a certain shape and size made from steel ingots and steel billets through pressure processing. It is an important material indispensable for national construction and the realization of the four modernizations. Steel is an important supporting material in various infrastructures.

[0003] Hoisting refers to the installation and positioning of equipment by cranes or lifting mechanisms. During the inspection or maintenance process, various lifting machines are used to lift equipment, workpieces, tools, materials, etc. to change their position. Steel is widely used in various fields and in many types. The production and processing of steel requires a variety of devices or tools, among which a steel production hoisting device will be used.

[0004] In view of the existing patent CN202022234955.7, a steel production hoisting device is provided. When the steel is hoisted inside the device, the motor drives the threaded rod to rotate, and the sliding block drives the clamping blocks on both sides to move up and down, so as to facilitate the clamping and lifting of the steel. The technical effect of using threaded rods instead of wire ropes for hoisting work solves the technical problem that hoisting tools usually use wire ropes, which are prone to shaking during work and affect production safety. However, the device only adjusts the height of the cross brace through a telescopic cylinder, which has poor stability and is easy to cause damage to the telescopic cylinder. At the same time, the device cannot adjust the angle during hoisting, and has poor practicality. Therefore, it does not meet the existing needs. In this regard, we propose a steel production hoisting device. Utility Model Content

[0024] See also Figures 1 to 4 The utility model provides an embodiment: a steel production hoisting device, comprising a base 1, a supporting plate 2 is arranged above the base 1, a support box 3 is fixedly connected to the central end of the upper surface of the supporting plate 2, and a connecting box 7 is arranged above the supporting box 3, a hoisting mechanism 4 is fixedly arranged above the connecting box 7, and rollers 8 are fixedly arranged at the four end corners of the bottom surface of the base 1, characterized in that: a lifting component 6 is arranged between the base 1 and the supporting plate 2, and fixing components 5 are fixedly connected to both sides of the base 1;

[0025] Wherein, the lifting assembly 6 includes four lower mounting blocks 601 and four upper mounting blocks 602, and the four lower mounting blocks 601 are respectively fixedly mounted at the four corners of the upper surface of the base 1, and the four upper mounting blocks 602 are respectively fixedly mounted at the four corners of the lower surface of the supporting plate 2, and a two-way threaded rod 603 is rotatably mounted between the two lower mounting blocks 601 on the front and rear sides, and each of the two-way threaded rod 603 is threadedly connected to a lower moving seat 604 on both sides, and a sliding rod 605 is fixedly mounted between the two upper mounting blocks 602 on the front and rear sides, and each of the sliding rods 605 is slidably connected to an upper moving seat 606 on both sides, and a support rod 607 is movably mounted between the lower moving seat 604 and the upper moving seat 606 arranged on the diagonal line;

[0026] The fixing component 5 includes a built-in plate 52 and a screw 53. Storage grooves 51 are provided on both sides of the base 1. One end of the built-in plate 52 is hinged to the storage groove 51, and the other end is threadedly matched with the screw 53. A clamping plate 54 is provided at one end of the screw 53 close to the ground, and a rotating handle 55 is provided at the other end.

[0027] The two bidirectional threaded rods 603 are both fixedly mounted with motors 608 which are fixedly connected to the upper surface of the base 1 through a fixing block. By adopting the above technical solution, the bidirectional threaded rods 603 can be rotated by starting the motors 608 when in use.

[0028] The bottom surface of the lower moving seat 604 is in contact with the upper surface of the base 1 , and the two lower moving seats 604 arranged on the front side and the two lower moving seats 604 arranged on the rear side are both symmetrically arranged, and the two upper moving seats 606 arranged on the front side and the two upper moving seats 606 arranged on the rear side are both symmetrically arranged.

The rotation of the two bidirectional threaded rods 603 is achieved by rotating the two rotating wheels 608, and the lifting assembly 6 is operated in the reverse direction to put down the hoisting mechanism 4, which is conducive to stable movement. Compared with the original device, the present device has higher structural stability, is not easy to be damaged, can extend the service life, and is convenient for adjusting the angle of the clamped steel material and performing transfer work;

[0034] Through the rotating groove 35 and the ball 72, the rotating shaft 32 drives the connecting box 7 to rotate while driving the ball 72 at the bottom end of the support column 71 to rotate in the rotating groove 35. The ball 72 rolls and fits against the inner wall of the rotating groove 35, reducing the friction between the support column 71 and the rotating groove 35, and reducing the wear of the support column 71 caused by friction.
