[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4The utility model provides an embodiment: a lifting and hoisting machine for special equipment, comprising a support column 1, a fixed plate 101 being fixedly connected to the lower end of the support column 1, a circular table 103 being fixedly connected to the upper end of the support column 1, a fixed shaft 104 being fixedly connected to the middle part of the upper end of the circular table 103, a boom 2 being rotatably connected to the upper end of the fixed shaft 104, a transmission box 6 being provided on one side of the upper end of the boom 2, a second drive motor 601 for driving the boom 2 to rotate being fixedly provided inside the transmission box 6, a movable groove 201 being provided inside the boom 2, a screw 4 being rotatably connected to the middle part of the movable groove 201, a motor groove 202 being provided inside the boom 2 and on one side of the movable groove 201, a sliding sleeve 5 being sleeved and slidably connected to the boom 2, and an electric hoist 503 being fixedly connected to the lower end of the sliding sleeve 5.

[0024] Furthermore, a shear support plate 102 is fixedly connected between the upper end of the fixing plate 101 and the lower ends of the four end surfaces of the support column 1. The fixing plate 101 is fixed to the ground by multiple bolts to fix the support column 1, and the shear support plate 102 provides a connection between the support column 1 and the fixing plate 101 to prevent bending between the support column 1 and the fixing plate 101.

[0025] Furthermore, a rotation groove 203 is provided at one end of the boom 2, and a fixed tube 3 is fixedly connected to the upper end surface of the rotation groove 203 and the upper end surface of the boom 2. The upper end of the fixed tube 3 extends to the inside of the transmission box 6 and is fixedly connected to the worm gear 301 on the outer end surface.

[0026] Furthermore, one side of the upper end of the fixed shaft 104 passes through the rotating groove 203 and the fixed tube 3 to extend into the interior of the transmission box 6 and is fixedly connected to the fixed ring 105. The upper end of the fixed shaft 104 passes through the fixed ring 105 and is fixedly connected to the upper end surface of the transmission box 6, so that the boom 2 can be rotated through the fixed shaft 104, which makes it convenient for the special equipment to be lifted by the electric hoist 503 and then lifted in different directions by rotating the boom 2.

[0027] Furthermore, the output shaft of the second drive motor 601 is fixedly connected to a worm 602, which is engaged with the teeth of the worm gear 301 on the fixed tube 3. The worm 602 is driven by the second drive motor 601 to rotate, thereby driving the fixed tube 3 to rotate, so that the fixed tube 3 drives the boom 2 to rotate.

[0028] Furthermore, a first drive motor 401 is fixedly installed inside the motor slot 202 , one end of the screw 4 extends into the motor slot 202 and is fixedly connected to the output shaft of the first drive motor 401 , and the screw 4 is driven to rotate by the first drive motor 401 .

[0029] Furthermore, a slider 501 is fixedly connected to the inside of the sliding sleeve 5, and a threaded hole 502 is provided in the middle of the slider 501. The slider 501 is inserted into the movable groove 201 and the screw 4 is threadedly connected through the threaded hole 502. When the screw 4 rotates, it drives the slider 501 to slide horizontally along the inside of the movable groove 201, so that the sliding sleeve 5 moves on the boom 2.

[0030] Working principle: When in use, first, the fixing plate 101 is firmly fixed to the ground by bolts. The presence of the shear support plate 102 effectively enhances the connection strength between the support column 1 and the fixing plate 101, preventing the structure from bending or shaking during the hoisting process. Subsequently, according to the hoisting requirements, the first drive motor 401 in the motor slot 202 is started, and its output shaft drives the screw 4 to rotate. Since the slider 501 inside the sliding sleeve 5 is tightly threaded with the screw 4 through the threaded hole 502, the rotation of the screw 4 will drive the slider 501 and the entire sliding sleeve 5 to slide horizontally along the movable slot 201 inside the boom 2, thereby accurately adjusting the position of the electric hoist 503 on the boom 2. The special equipment is lifted vertically by the electric hoist 503, and the worm 602 on the output shaft of the second drive motor 601 in the transmission box 6 is precisely engaged with the worm gear 301 on the outside of the fixed tube 3. When the second drive motor 601 is started, the rotation of the worm 602 drives the worm gear 301 and the fixed tube 3 to rotate together. Since the fixed tube 3 is fixedly connected to the upper end surface of the boom 2, this rotational motion is ultimately transmitted to the boom 2, causing it to rotate omnidirectionally around the fixed axis 104. In this way, the hoisted object, in addition to being vertically hoisted by the electric hoist 503, can also be flexibly moved in different directions as the boom 2 rotates, greatly expanding the scope and flexibility of the hoisting operation.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
