Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a building construction object lifting machine. Background Technology

[0002] A crane is a piece of equipment used for lifting and transporting materials during construction. For example, a construction crane provided in application number 202420664382.7 includes a counterweight, a boom, a support boom, a hook, steel cables, and a winch. The counterweight is equipped with a movable adjustment seat assembly, which includes a track groove, a movable track bar, a strip groove, a connecting bar, and a telescopic handle. The track groove is located on the bottom surface of the counterweight and has an open outer end. The movable track bar is slidably disposed inside the track groove. When it is necessary to maintain the stability of the device, not only can the counterweight be adjusted, but the movable track bar can also be extended from inside the track groove through the telescopic handle and the connecting bar, thereby increasing the force-bearing area between the counterweight and the ground and improving the stability of the device. The advantage of this design is that it provides another way for the device to maintain stability, and the adjustment is simple and quick. When retracted, it is also convenient for moving the device, making the use of the device more flexible and convenient for users.

The electromagnet 304, electronic button 306, and button battery 305 are all electrically connected.

[0021] The working process of this utility model is as follows: When the construction hoist designed using this scheme is in operation, the movable seat 6 is pushed to move the movable seat 6 and the hoist body 1 to the construction site. The hoist body 1 is started, and the motor inside the hoist body 1 releases the cable. The hook at the bottom of the cable falls to the ground. The worker hangs the hanging basket on the hook and pushes the left sliding ring 301 and the right sliding ring 302. The left sliding ring 301 and the right sliding ring 302 move closer to and are pressed against the hanging basket. The electronic button 306 is pressed, which activates the electromagnet 304. The electromagnet 304 will attract the hook, thereby lifting the left sliding ring 301 and the right sliding ring 302. The right sliding ring 302 is fixed on the lifting ring. The fixed left sliding ring 301 and right sliding ring 302 will abut against the hanging basket lug, pushing the pressure rod 307. The pressure rod 307 will rotate downward and approach the right sliding ring 302. Rotate the limit pin 308 so that the limit pin 308 is aligned with the positioning groove 310. Continue to push the pressure rod 307. The pressure rod 307 will fall down to the outer wall of the right sliding ring 302. The limit pin 308 passes through the positioning groove 310. Release the limit pin 308. The spiral spring 309 drives the limit pin 308 to rotate in the opposite direction. The reverse-rotating limit pin 308 will lock the pressure rod 307. The fixed pressure rod 307 will press against the hanging basket lug. The controller 5 activates the electric push rod 202, which pushes the squeezing block 203 downward. The downward-moving squeezing block 203 squeezes the mounting plate 204. The squeezed mounting plate 204 drives the connecting plate 205 and the cleaning plate 206 to move outward. The lower edge of the inner wall of the outward-moving cleaning plate 206 will be close to the cable of the crane body 1. The crane body 1 retracts the cable. The retracted cable pulls the basket upward through the hook. At the same time, the retracted cable passes through the fixing box 201. The cleaning plate 206 in the fixing box 201 scrapes off the debris attached to the cable. When the basket rises to the appropriate position, the crane body 1 stops retracting the cable. The electric push rod 202 drives the squeezing block 203 upward. The squeezing block 203 stops squeezing the mounting plate 204. The return spring 212 pulls the mounting plate 204 inward. The mounting plate 204 drives the connecting plate 205 and the cleaning plate 206 away from the cable. When the cleaning plate 206 is damaged, remove the sealing cover 213. The controller 5 starts the servo motor 211. The servo motor 211 drives the worm wheel 209 to rotate via the worm gear 210. The rotating worm wheel 209 drives the mounting plate 207 to rotate downwards. The downward rotation of the mounting plate 207 causes the positioning block 208 to disengage from the connecting plate 205. The mounting plate 207 no longer presses against the connecting plate 205. Pull the cleaning plate 206 to remove it from the fixing box 201. Then, put the new cleaning plate 206 in. Inside the fixed box 201, the connecting plate 205 on the outer wall of the new cleaning plate 206 will be inserted into the mounting plate 204. The servo motor 211 drives the worm wheel 209 to rotate in the opposite direction through the worm gear 210. The worm wheel 209 rotates in the opposite direction, which drives the mounting plate 207 to rotate upward. The upward rotating mounting plate 207 drives the positioning block 208 to be inserted into the connecting plate 205. The mounting plate 207 then locks the connecting plate 205 in place. Finally, the sealing cover 213 is reinstalled at the bottom of the fixed box 201, completing the replacement of the cleaning plate 206.

[0022] 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 these 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.
