Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a lifting device for building construction. Background Art

[0002] During construction, some buildings or facilities require the installation of pipes, and some larger pipes are usually lifted by cranes when they need to be transported. However, during lifting, due to the overall length and weight of the pipes, the construction site usually uses ropes and other lifting tools to tie the pipes before lifting. The connection between the pipes and the hooks is relatively unstable, and the pipes are easily affected by factors such as wind, causing the pipes to swing greatly during lifting, which is relatively inconvenient. In addition, before loading the pipes, the lifting tools need to be used to connect the pipes to the hooks at the center to maintain the lifting stability. When the pipe is lifted, the center of gravity is located at the hook, making the pipe more stable during lifting. However, if the initial fixing of the sling is incorrect and the position of the sling on the pipe needs to be adjusted, the existing sling is not convenient for adjusting the relative position of the pipe and the sling, which is relatively inconvenient. Moreover, when the pipe is lifted to the appropriate position and needs to be installed or unloaded, the position of the pipe during lifting may have a certain error with the unloading point. Due to the small error, it is difficult to use the crane to control the movement and adjustment of the pipe position. Usually, the pipe position is adjusted manually with tools, which is relatively inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 In an embodiment of the present invention, a construction hoist comprises:

[0024] The plate body 100, a stabilizing mechanism 200 capable of reducing the swing of the pipe, two moving mechanisms 300 capable of moving the pipe and a supporting mechanism 400, a hanging ring 110 is fixedly connected to the center of the top surface of the plate body 100, the stabilizing mechanism 200 is located above the plate body 100, the stabilizing mechanism 200 includes two rotating rods 210, and the bottom ends of the two rotating rods 210 are respectively rotatably connected to the two ends of the top surface of the plate body 100, a socket is opened in the center of one side of the two rotating rods 210, and a plug rod 220 is fixedly sleeved inside the two sockets, both ends of the two plug rods 220 are rotatably connected to the rotating plates 230, and a bolt hole 231 for bolt connection is opened on one side of the four rotating plates 230, the two moving mechanisms 300 are both located below the plate body 100, and the supporting mechanism 400 is located between the two moving mechanisms 300.

[0025] Specifically, after the pipes on the vehicle arrive at the construction site, the two moving mechanisms 300 can be used to clamp the pipes on the vehicle, and then the crane hook can be used to hook the pipes on the lifting ring 110. Since the hook of a general crane is provided with a pulley block, and the hook pulley block and the boom top pulley block are often connected by multiple sets of steel wire ropes, the hook is not easy to swing or rotate during lifting. The stabilizing mechanism 200 is used to resist the hook, so that the connection between the plate body 100 and the hook is relatively stable, which reduces the swinging and rotating of the pipes during lifting. When users are loading, unloading, and laying pipes, when using the stabilizing mechanism 200, the users can rotate the two rotating rods 210 so that the top ends of the two rotating rods 210 touch the opposite sides of the hook, and rotate the two rotating plates 230 at the same end of the two connecting rods 220 so that the multiple bolt holes 231 on the two rotating plates 230 are aligned, and then use multiple bolts to pass through the multiple bolt holes 231 and then screw them into nuts to fix the positions of the two rotating rods 210, so that the relative position between the plate body 100 and the hook is fixed.

[0026] Example 1

[0027] like Figure 2 As shown, in this embodiment, the length of one plug rod 220 is greater than the length of the other plug rod 220 , and the top ends of the two rotating rods 210 are both rotatably connected to the abutment plate 211 .

[0028] In this embodiment, the length of one connecting rod 220 is greater than that of the other connecting rod 220, so that the rotating plates 230 at the same end of the two connecting rods 220 are in a staggered arrangement, which facilitates the rotation plates 230 on the two connecting rods 220 to be aligned with the bolt holes 231 and then fixed with bolts. The contact area between the top of the rotating rod 210 and the hook is increased by the abutment plate 211, thereby improving the stability of the rotating rod 210 when it contacts the hook.

[0029] like Figure 3 As shown, in this embodiment, the moving mechanism 300 includes:

[0030] The U-shaped plate 310 and the two U-shaped frames 320, have notches on opposite sides of the U-shaped plate 310, and the top center of the U-shaped plate 310 is rotatably connected to a support arm 311, and one end of the support arm 311 is rotatably connected to the bottom surface of the plate body 100, and the two opposite sides of the U-shaped plate 310 are rotatably connected to two screws 312, and the two U-shaped frames 320 are respectively located inside the two notches, and multiple card rollers 321 are rotatably connected between the two arms of the two U-shaped frames 320, and one side of the two U-shaped frames 320 is fixedly connected to a motor box 322, and the two motor boxes 322 are equipped with drive motors, and the motor shafts of the two drive motors are fixedly connected to one end of the adjacent card roller 321, and both ends of the two U-shaped frames 320 are fixedly connected to a support plate, and one end of any support plate is provided with a threaded hole, and the inner side walls of the threaded holes on the four support plates are respectively screwed with the outer side walls of the four screws 312, and any card roller 321 is a spindle-shaped structure.

[0031] In a specific implementation, the U-shaped plates 310 on the two moving mechanisms 300 are clamped above the pipe so that the pipe is located between the two arms of the U-shaped plate 310. Then, the user rotates the multiple screws 312 to adjust the relative position of the U-shaped frame 320 on the U-shaped plate 310 and the U-shaped plate 310, so that the two U-shaped frames 320 on the same U-shaped plate 310 clamp the pipe and the pipe is clamped in the middle depression of the clamping roller 321 on the U-shaped frame 320, thereby fixing the pipe. The outer surface of the clamping roller 321 is coated with a material with a large friction force with the surface of the pipe. The user can start the drive motor to drive The adjacent clamping rollers 321 rotate, so that the clamping rollers 321 drive the pipe to move, so that the pipe is moved to a suitable position. When the hook is lifting, if the initial installation position of the two U-shaped plates 310 is not located in the center of the pipe, the user can use the clamping rollers 321 to drive the pipe to move, so that the two U-shaped plates 310 are located in the center of the pipe, so that the pipe is more stable during lifting. After the pipe is lifted to a suitable position, the clamping rollers 321 can be used to drive the pipe to move, so that the pipe is moved to a suitable unloading or installation position. There is no need to use a crane or manual force to adjust the position of the pipe, which is convenient for users to unload or install the pipe.

[0032] like Figure 4 As shown, in this embodiment, the support mechanism 400 includes:

[0033] Two frames 410, multiple support rods 420 and two pressure plates 430, the bottom surfaces of the two frames 410 are fixedly connected to the top surfaces of the U-shaped plates 310 on the two moving mechanisms 300, the multiple support rods 420 are located between the two frames 410, and the two ends of any support rod 420 pass through the interior of the two frames 410 respectively. The two pressure plates 430 are respectively located inside the two frames 410, and the top surfaces of the two pressure plates 430 are rotatably connected with multiple screw-on rods 431. The top surface of any frame 410 is provided with multiple screw-on holes, and the multiple screw-on holes correspond one-to-one to the adjacent multiple screw-on rods 431. The outer wall of any screw-on rod 431 is screwed with the inner wall of the corresponding screw-on hole.

[0034] During specific implementation, the user can insert multiple support rods 420 into the two frames 410 and adjust the distance between the two frames 410, thereby adjusting the distance between the two U-shaped plates 310, and then rotate the screw-on rod 431 to drive the pressure plate 430 to press down, press and fix the multiple support rods 420, thereby fixing the distance between the two U-shaped plates 310.

[0035] Example 2

[0036] On the basis of the first embodiment, the contact surface between the pressing plate 430 and the support rod 420 is increased by providing the arc strip 440 .

[0037] like Figure 4As shown, in this embodiment, a plurality of arc-shaped bars 440 are fixedly connected to the bottom surfaces of the two pressing plates 430 , and the plurality of arc-shaped bars 440 on any pressing plate 430 correspond one-to-one to the plurality of support rods 420 .

[0038] In a specific implementation, when the pressing plate 430 is pressed down, the support rod 420 can be embedded in the arc strip 440 , and the arc strip 440 is used to increase the contact surface with the support rod 420 , thereby improving the fixing effect of the pressing plate 430 on the support rod 420 .

[0039] 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.
