[0041] Referring to Figure 1 , Figure 4 and Figure 5The quick mounting mechanism 2 comprises two positioning rods 201 fixedly connected to the inner wall bottom of the corresponding support seat 5, which provides an initial positioning reference for the mounting of the cross beam 6. The bottom of the cross beam 6 is provided with a positioning hole 202 on the left and right sides, and the two positioning rods 201 are respectively clamped with the corresponding positioning hole 202. The horizontal position of the cross beam 6 on the support seat 5 is preliminarily determined through this clamping mode. The top of the cross beam 6 is fixedly connected with a fixed block 203 on the left and right sides, which provides a mounting and sliding space for the insertion rod 204. The inner wall of the two fixed blocks 203 is slidingly connected with the insertion rod 204, which slides in the fixed block 203 to realize different connection and disassembly states. The outer wall of the middle part of the two insertion rods 204 is fixedly connected with a fixed plate 205, which is used to connect the spring 206 and transmit the force of the spring 206. The adjacent side of the two fixed plates 205 is fixedly connected with the spring 206, which provides elastic force to assist the insertion rod 204 to realize automatic clamping and disengagement action. The adjacent end of the two springs 206 is fixedly connected with a support plate 207, which stably transmits the elastic force of the spring 206 to the insertion rod 204 and is fixed with the cross beam 6. The two support plates 207 are fixedly connected with the cross beam 6, which ensures that the whole structure becomes a stable whole with the cross beam 6. The two support plates 207 are respectively slidingly connected with the corresponding insertion rod 204, which ensures that the insertion rod 204 can smoothly slide under the action of the spring 206. The top of the cross beam 6 is fixedly connected with a bidirectional telescopic rod 209, which is used to control the movement of the insertion rod 204.

At this time, the cross beam 6 can be easily removed from the support seat 5. The whole process realizes quick and stable connection and disassembly operation through ingenious structural design.

[0043] With reference to Figure 1 , Figure 2 and Figure 4 , the top of each of the plurality of threaded rods 12 is fixedly connected with a handle 18, and the surface of each of the plurality of handles 18 is provided with anti-skid treatment. The handle 18 provides a force application site for an operator to rotate the threaded rod 12, facilitating operation of the threaded rod 12. The anti-skid treatment increases the friction between the hand and the handle 18, ensuring that the hand does not easily slip when the operator rotates the handle 18, making the operation more stable and reliable. The top of each of the two bases 1 is fixedly connected with a lamp holder 19 for mounting and fixing a lighting lamp 20, thereby providing support and a mounting basis for the lighting lamp 20. The top of each of the two lamp holders 19 is fixedly connected with a plurality of lighting lamps 20 at equal intervals on the front and rear sides. The lighting lamps 20 provide illumination during hoisting operations, ensuring that the operator can clearly observe the working conditions in a relatively dark environment, thereby ensuring safe and smooth operation.

[0044] Specifically, the surface of the handle 18 is provided with anti-skid treatment, facilitating rotation of the threaded rod 12 by an operator to adjust the positioning plate 11 to fit different slope placement surfaces. The plurality of lighting lamps 20 are fixed on the lamp holder 19 at equal intervals on the front and rear sides, thereby providing illumination for beam and column dismantling operations, facilitating construction under different light conditions.

[0045] With reference to Figure 1 , Figure 3 and Figure 5The outer wall of the right side support base 5 is fixedly connected with a mounting box 21, which provides a stable mounting position for the alarm lamp 22, and plays a role of protecting and positioning the alarm lamp 22; the inner wall of the mounting box 21 is fixedly connected with the alarm lamp 22, which can send a warning signal when the device appears an abnormal condition; the outer wall of the right side support leg 3 is fixedly connected with a controller 23, which is electrically connected with the two telescopic joints 4 and the moving box 7 respectively, so that the operator can accurately control the telescopic action of the telescopic joint 4 by using the controller 23 to adjust the overall height of the hoisting frame, and can also control the movement of the moving box 7 on the cross beam 6, thereby meeting the adjustment requirements of height and transverse position in different hoisting scenes, and improving the flexibility and accuracy of hoisting operation;

[0046] Specifically, when the device appears an abnormal condition, the alarm lamp 22 sends a warning to remind the operator, and the controller 23 is electrically connected with the two telescopic joints 4 and the moving box 7, so that the telescopic height of the telescopic joint 4 and the position of the moving box 7 can be conveniently controlled to realize accurate operation.

[0047] Working principle: When facing different slope placement surfaces, rotating the threaded rod 12 will produce up and down displacement, which is transmitted to the ball head 13 connected to the bottom of the threaded rod 12, so that it moves in the ball groove 14 on the top of the positioning plate 11. Due to the sliding connection between the ball head 13 and the ball groove 14, the positioning plate 11 is driven to rotate around the rotating rod 10. By finely adjusting the rotation degree of the threaded rod 12, the inclination angle of the positioning plate 11 can be changed to closely fit different slope placement surfaces such as ground, ensuring that the hoisting frame can be stably placed on uneven or sloping sites, providing a solid foundation for hoisting operation. The telescopic joint 4 is stably fixed in the inner wall of the support leg 3. When facing different height requirements, the operator can flexibly operate the telescopic joint 4. When demolishing beams on higher building floors, the telescopic joint 4 is elongated, which drives the support base 5, the cross beam 6, the moving box 7 and the lifting hook 8 connected thereto to rise together to reach the appropriate lifting height to meet the operation requirements. When operating in a lower space, the telescopic joint 4 is retracted to reduce the overall height. Through these two adjustment methods, the applicability and stability of the hoisting frame are greatly enhanced, so that it can be used for beam and column demolition and hoisting operation in various complex scenes;

[0048] And when installing the crossbeam 6, the crossbeam 6 is aligned with the support base 5 and is moved downward, at this time, the positioning rod 201 is accurately inserted into the corresponding positioning hole 202 on the left and right sides of the bottom of the crossbeam 6, the preliminary positioning of the crossbeam 6 is completed, and the horizontal position is ensured to be accurate, at the same time, the insertion rod 204 in the fixed block 203 on the top left and right sides of the crossbeam 6 will be extruded from the corresponding part of the support base 5, since the middle part of the outer wall of the insertion rod 204 is connected with the fixed plate 205, and the fixed plate 205 is connected with the support plate 207 through the spring 206, after the insertion rod 204 is extruded, the spring 206 will be compressed, and the insertion rod 204 will slide to the inside of the fixed block 203, when the crossbeam 6 is moved to the accurate position, the insertion rod 204 is accurately aligned with the insertion hole 210 on the outer wall of the positioning rod 201, and is clamped into the insertion hole 210 under the partial elastic force of the spring 206, thereby further stabilizing the connection between the crossbeam 6 and the support base 5, and ensuring the firmness of the connection, when the crossbeam 6 needs to be removed, the operator only needs to operate the bidirectional telescopic rod 209 to make it contract, during the contraction process of the bidirectional telescopic rod 209, the iron chain 208 at both ends will be pulled, the iron chain 208 drives the insertion rod 204 to overcome the elastic force of the spring 206, and the insertion rod 204 is smoothly separated from the insertion hole 210 of the positioning rod 201, at this time, the crossbeam 6 is no longer fixedly constrained, and can be easily removed from the support base 5.

[0049] Finally, it should be noted that: the above only for preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
