Description

Technical Field

[0001] The utility model belongs to the technical field of boom installation tools, in particular to a boom installation lifting device. Background Art

[0002] With the rapid development of the construction industry, the role of hangers in the construction industry is increasing day by day. In the traditional construction process, the hanger is generally installed by manually lifting the hanger with a hanger sleeve assembly. The hanger sleeve assembly is sleeved on the hanger. When the top of the hanger is installed into the hole, the hanger sleeve assembly is rotated to drive the nut on the top of the hanger to rotate, so that the nut is tightened and pushes the expansion screw cylinder to expand and fix it in the hole.

[0003] During this installation process, if the ceiling height is too high, workers are required to use ladders to install it, which creates safety risks in high-altitude construction. In addition, in traditional boom installation construction, workers are located directly below the boom. In order to ensure that the boom is installed into the hole, they need to keep their heads up for a long time and lift the boom sleeve assembly for a long time, which makes the workers very prone to fatigue, which not only affects the construction quality, but also causes safety accidents due to worker fatigue. Summary of the invention

[0004] The purpose of the utility model is to provide a boom installation lifting device to address the problems existing in the prior art, thereby solving the problem that workers need to lift the boom for a long time and keep their heads up for a long time to observe the boom installation status, which makes the workers very easy to get tired, thereby affecting work efficiency and construction quality.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a boom installation lifting device, comprising a mobile work box and a lifting rod, the top of the mobile work box is provided with a lifting seat for lifting the lifting rod, the top of the lifting rod is provided with a piston telescopic rod, the movable end of the piston telescopic rod is provided with a sleeve rod, and the top of the sleeve rod is provided with a knob seat;

[0006] The knob seat includes a shell arranged at the top end of the sleeve rod, a knob wheel and a clamping seat arranged on the upper and lower sides of the top wall of the shell and cooperating with each other, the knob wheel is rotatably connected to the shell, and the top end of the clamping seat is provided with a through-slot group vertically penetrating the clamping seat for suspending the suspension rod, and also includes a driving member arranged on the side of the shell for driving the knob wheel to rotate, and a small camera arranged on the other side of the shell for observing the suspension rod mounting tube of the suspension rod installed on the ceiling wall.

[0007] The lifting rod is raised by the lifting seat to realize the lifting operation of the boom, which replaces the purpose of manually lifting the boom. The installation holes on the ceiling are photographed by a small camera at all times, instead of manually looking up to observe the relative positions of the installation holes and the top of the boom. This makes it easier for workers to align the top of the boom with the installation holes, making it easier for workers.

[0008] After the top of the hanger rod is aligned with the mounting hole on the ceiling, the piston telescopic rod is used to knock the hanger rod in the sleeve rod upward to insert the top of the hanger rod into the mounting hole. Then the direction of the knob seat is adjusted to allow the nut on the hanger rod to be stuck in the card slot group. Then the knob wheel and the card seat are driven to rotate through the driving part, which in turn drives the nut on the hanger rod to rotate. The lifting rod is continuously lifted by the lifting seat, so that the nut on the hanger rod can be tightened and the expansion screw cylinder can be pushed to expand and fix it in the hole, thereby completing the installation of the hanger rod.

[0009] Optionally, universal wheels are provided on all four sides of the bottom of the mobile work box, a sleeve for guiding the lifting rod is provided inside the mobile work box and directly below the lifting seat, an air pump for providing power to the piston telescopic rod is provided inside the mobile work box, the output end of the air pump is connected to the piston telescopic rod through an air pipe, and a display device is placed on the top wall of the mobile work box.

[0010] The sleeve allows the lifting rod to be in a relatively stable state after being inserted into the mobile work box, and also allows the lifting rod to be lifted and lowered more stably. The air pump provides intermittent air source to the piston telescopic rod, allowing the piston telescopic rod to repeatedly extend and retract, thereby achieving the effect of hammering the bottom of the hanging rod, making it easier for the top of the hanging rod to be inserted into the installation hole on the ceiling. The display device can view the shooting picture of the small camera in real time, making it convenient for workers to control the installation progress.

[0011] Optionally, the lifting seat includes a driving wheel seat and a passive wheel seat which are relatively arranged on the top wall of the mobile working box. The surface of the wheel body of the driving wheel seat is provided with an outer ring groove for accommodating the lifting rod. The driving wheel seat and the passive wheel seat have the same structure and also include a driving motor arranged on one side of the driving wheel seat to drive the wheel body of the driving wheel seat to rotate.

[0012] The lifting rod is clamped by the driving wheel seat and the passive wheel seat, and when the driving wheel seat rotates, an upward or downward thrust is generated on the lifting rod, thereby realizing the lifting and lowering of the lifting rod.

[0013] Optionally, a docking seat threadedly connected to the lifting rod is provided at the bottom of the piston telescopic rod, a docking ring threadedly connected to the sleeve rod is provided at the top of the piston telescopic rod and located at the periphery of the movable end of the piston telescopic rod, and a hammer head is welded to the movable end of the piston telescopic rod.

[0014] Air is instantly injected into the piston telescopic rod through an air pump, thereby driving the movable end of the piston telescopic rod to move upward instantly until the hammer head hits the bottom end of the suspension rod, thereby allowing the suspension rod to be nailed into the installation hole of the ceiling.

[0015] Optionally, a docking plate threadedly connected to the sleeve rod is welded to the bottom of the shell, a bottom hole with a diameter larger than the suspension rod is opened on the bottom wall of the shell, and an installation opening for accommodating the knob wheel is opened on the top wall of the shell.

[0016] The shell and the sleeve rod can be removed at any time through the docking plate, and the bottom hole at the bottom of the shell allows the suspension rod in the shell to slide up and down freely.

[0017] Optionally, the knob wheel includes a knob gear ring and a knob tube welded to the top of the knob gear ring, the inner diameters of the knob gear ring and the knob tube are equal, and threaded grooves are provided on the inner walls of the knob gear ring and the knob tube, the knob tube passes through the placement port, and the knob tube is rotatably connected to the shell.

[0018] The knob wheel is used as a driving member to drive the intermediate member to rotate the locking seat. In order to make the knob wheel rotate more smoothly, a number of sliding balls are embedded at the top of the knob gear ring and on the outer periphery of the knob tube, so that the sliding balls contact the inner top wall of the shell to reduce the friction between the knob wheel and the shell.

[0019] Optionally, the clamping seat includes a clamping plate and a docking sleeve welded to the bottom of the clamping plate, and the docking sleeve is threadedly connected to the knob sleeve.

[0020] The knob wheel and the clamping seat are connected together by the cooperation of the docking tube and the knob tube, and the docking tube can drive the knob tube to rotate synchronously.

[0021] Optionally, the insertion slot group includes a through hole and a hexagonal slot located above the through hole, the inner diameter of the through hole is larger than the diameter of the suspension rod, and the size of the hexagonal slot matches the mounting nut on the suspension rod.

[0022] After the top of the hanger is nailed into the mounting hole on the ceiling, the nut on the hanger can be stuck in the hexagonal slot as the lifting rod continues to rise, and then the nut can be driven to rotate through the driving part, thereby realizing the pushing work of the expansion screw cylinder until the final installation step of the hanger is completed.

[0023] Optionally, the driving member includes a knob motor arranged on the side wall of the shell and a driving gear arranged at the output end of the knob motor and meshing with the knob gear ring, and a notch adapted to the driving gear is opened on the outer side of the shell.

[0025] Compared with the prior art, the beneficial effects of the utility model are: the height of the lifting rod is raised by the lifting seat, and then the lifting operation of the suspension rod is realized, so as to replace manual lifting of the suspension rod and reduce the labor intensity of workers. The installation hole on the ceiling is constantly photographed by a small camera, so as to replace manual observation of the relative position of the installation hole and the top of the suspension rod, which is convenient for workers to align the top of the suspension rod with the installation hole, and also makes workers more relaxed. The driving member drives the knob wheel and the positioning seat to rotate, and then drives the nut on the suspension rod to rotate. With the lifting seat continuously lifting the lifting rod, the nut on the suspension rod can be tightened and the expansion screw cylinder can be pushed to expand and fix it in the hole, so that the installation of the suspension rod can be completed. Semi-automation is realized during the installation process, which improves work efficiency and ensures consistent construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

The knob tube 722 passes through the placement opening, and the knob tube 722 is rotatably connected to the shell 71.

[0059] The knob wheel 72 is used as a driving member to drive the locking seat 73 to rotate. In order to make the knob wheel 72 rotate more smoothly, a number of sliding balls are embedded at the top of the knob gear ring 721 and on the periphery of the knob tube 722. The sliding balls contact the inner top wall of the shell 71 to reduce the friction between the knob wheel 72 and the shell 71.

[0060] The clamping seat 73 includes a clamping plate 731 and a docking tube 732 welded to the bottom of the clamping plate 731 , and the docking tube 732 is threadedly connected to the knob tube 722 .
