Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and specifically relates to a suspended platform hoisting device at beam corners. Background Technology

[0002] Currently, when constructing the exterior facade and other high-altitude work on the main building structure, conventional scaffolding is typically used for installing the suspended platform. However, unlike the straightforward installation of conventional scaffolding on straight sections of beams, at beam corners, conventional scaffolding is often difficult to fix due to span limitations, or the fixation process is quite complicated (e.g., ...). Figure 4 As shown), the operating range of the suspended platform cannot meet the construction angle requirements at the beam corner, making construction operations inconvenient at this location. Furthermore, conventional scaffolding installation relies on counterweights (such as...). Figure 4 As shown, the weight of the suspended platform needs to be balanced. When hoisting in a location without a floor slab, the counterweight needs to be suspended, which poses a high safety hazard. Summary of the Invention

[0003] The purpose of this invention is to provide a suspended platform hoisting device at beam corners to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A suspended platform hoisting device for beam corners includes: a support frame, a frame hoop, a rear support rod, and a front support rod. The main body of the support frame consists of two sets of base frames, each composed of two sets of parallel square tubes. The two sets of base frames are spliced ​​together to form a right-angle structure. Each end of the right-angle structure has a connecting pipe of a square tube structure vertically fixed to it. Each set of base frame square tubes has a pipe fitting vertically fixed to it, with the pipe fitting closer to the corner of the right-angle structure being the front upright pipe, and the pipe fitting further away from the corner being the rear upright pipe. Each set of connecting pipes has mounting holes at both ends, and a U-shaped frame hoop fits into the mounting holes. The frame hoop and the connecting pipe... The pipes form a complete square ring structure; a rod is embedded in the front riser to form a front support rod, and a rod is embedded in the rear riser to form a rear support rod. The upper ends of the rear support rod and the front support rod are connected and fixed. A hanger is vertically connected to the side of the front support rod away from the rear support rod, and a lever is vertically connected to the side of the rear support rod away from the front support rod. The hanger and the lever are arranged collinearly and at a 45-degree angle to the connecting pipe. A pull cable is rotatably connected to the end of the lever away from the rear support rod, and a ring-shaped cable clamp is connected to the other end of the pull cable. An adjustable horizontal hanger is connected to the hanger rod using a movable hanger.

[0006] Furthermore, in order to achieve horizontal position adjustment of the suspension cable, the movable suspension frame includes: wheel frame, support wheel, lifting ring, positioning hole, and anti-deviation wheel; the suspension rod is a channel steel with a longitudinal section of a regular "I" shape; there are two sets of wheel frames, which are fixedly connected at the bottom; each set of wheel frames has at least one set of support wheels on the side near the suspension rod, which is in contact with the lower inner surface of the suspension rod, and the support wheels and the suspension rod form a rolling pair; a lifting ring is fixed at the bottom of the wheel frame, and the suspension cable is connected below the lifting ring; a limiter is provided at the end of the suspension rod near the suspension cable to prevent the support wheel from falling off.

[0007] Furthermore, in order to fix the horizontal position of the suspension cable after adjusting the horizontal position of the movable gantry and the suspension cable, the end of the gantry near the suspension cable is provided with equally spaced adjustment holes, and the wheel frame is provided with positioning holes with the same inner diameter as the adjustment holes. The center line of the positioning holes and the center line of all the adjustment holes are located in the same plane.

[0008] Furthermore, in order to reduce the back-and-forth swaying of the suspension cable and the basket below it when adjusting the horizontal position of the movable gantry and the suspension cable, each set of wheel frames has at least two sets of support wheels on each side.

[0009] Furthermore, in order to reduce the lateral sway of the hoisting cable and the basket below it, each side of the wheel frame is provided with a notch, and each notch is fitted with an anti-deviation wheel by a vertical shaft. The anti-deviation wheel is made of flexible elastic material and rolls with the sides of the hoisting rod. The corresponding anti-deviation wheels of the two sets of wheel frames are elastically clamped to the sides of the hoisting rod by an interference fit.

[0010] Furthermore, in order to increase the bearing capacity of the boom and lever arm, the upper ends of the rear support rod and the front support rod are extended, and the extended ends are respectively fixed to the boom or lever arm on the same side by diagonal bracing. The diagonal bracing can be one of steel cable, rod or pipe.

[0011] Furthermore, in order to enable the pier frame to be compatible with hoops of different widths, that is, to be compatible with beams of different widths, the number of mounting holes on one side of the connecting pipe is at least two sets.

[0012] Furthermore, in order to increase the anti-deflection strength of the rear and front support rods under stress, the rear and front uprights on the pier frame are reinforced and connected to each other using a strip plate structure reinforcement frame.

[0013] In summary, the present invention has the following beneficial effects:

[0014] ① Achieve the required construction angle at the beam corner: By setting up a scaffolding frame, place the scaffolding frame at the corner of the installation beam, ensuring that the right-angled corner of the scaffolding frame coincides with the corner of the installation beam. Then, take two sets of scaffolding hoops and insert them into the mounting holes at both ends of the two sets of connecting pipes from below the installation beam. External threads are provided at both ends of the scaffolding hoops, and threaded nuts are used to tighten and fix the connecting pipes and scaffolding hoops onto the installation beam. Finally, fix two sets of cable hoops on the lower beam of the installation beam. The two sets of cable hoops are positioned at... Below the two sets of hoop clamps, use a cable to connect the end of the boom arm and the cable clamp, and tighten the cable. Then, adjust the position of the movable gantry on the boom according to the actual width of the suspended platform. At this time, the support wheels provide rolling assistance, and the anti-deviation wheels are used to prevent the movable gantry from swaying left and right on both sides of the boom. After the adjustment is completed, use a pin or bolt to insert / tighten in the positioning hole and its nearest adjustment hole to fix the movable gantry and the boom as a whole. Then, hang the suspended platform below the two sets of cables to achieve the construction angle requirements at the beam corner position.

[0015] ② Lifting operations can be carried out without relying on counterweights: By setting up cables and cable clamps, the ends of the boom and the cable clamps are connected by cables, and the cables are tightened to straighten them, which can balance the weight of the basket. There is no need to set up additional counterweights, which would increase the transportation costs of counterweights and the suspension risks. Attached Figure Description
