Description

Technical Field

[0001] This utility model belongs to the technical field of hoisting devices, and in particular to a hoisting device for steel structure profiles. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. When constructing a steel structure building, the steel structure needs to be lifted. When lifting the steel structure, clamps need to be placed in the center of the steel structure to hold it and lift it. The placement of the clamps mostly requires manual assistance. During lifting, the structure is prone to tilting due to the different weights at both ends. Therefore, the position of the clamps needs to be adjusted. The process of releasing the steel structure and adjusting its position again is quite cumbersome.

[0003] A search revealed a Chinese patent document (authorization announcement number CN222556337U) for a steel structure profile hoisting device, which includes a fixed plate and two hoisting plates. Both hoisting plates are fitted over the fixed plate, and U-shaped frames are fixedly installed on the bottom walls of both hoisting plates. Fixed rods are fixedly installed on the inner side walls of the U-shaped frames, and two second connecting rods are fitted on the side walls of the fixed rods. While the above device can automatically tighten and lift the steel structure, if clamping deviation occurs during actual use, the clamps need to be loosened and moved before being clamped again. This hoisting device is inconvenient for moving the clamps, therefore, a steel structure profile hoisting device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure profile hoisting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure profile hoisting device, comprising an installation plate for installing the steel structure profile hoisting device and a clamping plate for holding the steel structure profile, wherein two rectangular grooves are symmetrically opened on both sides of the installation plate, and two sliding plates are slidably installed in the plurality of rectangular grooves, and the clamping plate is fixedly installed on the bottom of the two sliding plates;

[0006] Each of the two clamping plates has a support plate fixedly installed on its bottom side opposite to the other side;

[0007] Multiple hydraulic cylinders are fixedly installed on the top surface of the mounting plate corresponding to the sliding plate. A connecting plate is fixedly installed on the top surface of each of the sliding plates. The telescopic ends of the hydraulic cylinders are fixedly connected to the side wall of the connecting plate.

[0008] Two sliding grooves are symmetrically opened on opposite sides of the two clamping plates, and abutment plates are slidably installed in each of the sliding grooves. A cylinder is fixedly installed on the side of the clamping plate away from the abutment plate, and the telescopic end of the cylinder slides into the sliding groove and is fixedly connected to the abutment plate.

[0009] The top surfaces of both pallets are provided with multiple arc-shaped grooves, and ball bearings are rolled inside each of the multiple arc-shaped grooves.

[0010] Preferably, limit strips are symmetrically fixedly installed on the side walls of the plurality of sliding plates, and strip grooves are symmetrically opened on the inner walls of the plurality of rectangular grooves.

[0011] Preferably, the limiting strips fixedly installed on the sidewall of the skateboard are slidably connected to the interiors of two strip-shaped grooves opened on the inner wall of the rectangular groove.

[0012] Preferably, the sidewalls of the abutment plate are symmetrically fixedly equipped with limiting blocks, and the inner wall of the slide groove is symmetrically provided with two limiting grooves.

[0013] Preferably, the two limiting blocks fixedly installed on the side wall of the abutment plate are slidably connected to the inside of the limiting groove opened on the inner wall of the slide.

[0014] Preferably, one side of the top surface of the two trays is an inclined surface.

[0015] Preferably, anti-slip pads are fixedly adhered to the side walls of the plurality of abutment plates.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This steel structure hoisting device, thanks to the design of hydraulic cylinders, sliding plates, connecting plates, and clamping plates, works by activating multiple hydraulic cylinders to push the sliding plates, which are fixedly installed at their telescopic ends, outward. This allows the two clamping plates to separate. The device is then placed on both sides of the steel structure to be hoisted. At this point, multiple hydraulic cylinders are activated again to retract the sliding plates into the rectangular groove. The two sliding plates move the two clamping plates at their bottoms toward the steel structure and clamp them. Simultaneously, the two support plates extend to the bottom of the steel structure. At this point, the bottom of the steel structure will contact multiple ball bearings on the top surface of the support plates. When it is necessary to adjust the clamping plates to the center position of the steel structure, the device can be moved under the action of the ball bearings.

[0018] This steel structure profile hoisting device benefits from the fact that the ends of the two support plates are set at an angle, which makes it easy for the support plates to be inserted into the bottom of the steel structure when the clamps are moved.

[0019] This steel structure hoisting device benefits from the design of a sliding groove, abutment plates, and cylinders. By activating the cylinder, the abutment plates slide outward, and the two abutment plates abut against the side wall of the steel structure under the push of the cylinder. The steel structure is then fixed by the two abutment plates, thereby further improving the stability of the steel structure during hoisting.

[0020] Compared with existing technologies, this steel structure profile hoisting device can facilitate the movement of the clamps in the hoisting device, thereby further improving the hoisting efficiency of steel structure profiles. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 3The main structure of the steel structure profile hoisting device shown is an installation plate 1 for installing the steel structure profile hoisting device and a clamping plate 4 for clamping the steel structure profile. The clamping plate 4 is longitudinally slidably installed below the installation plate 1. Most steel structure profiles are rectangular strips. When hoisting the steel structure, the clamps need to be placed in the middle of the steel structure to prevent deviation during hoisting. When manually adjusting the hoisting position, deviation is inevitable. Therefore, the position of the hoisting device needs to be adjusted before hoisting can be done again.

[0031] Two rectangular slots 2 are symmetrically opened on both sides of the mounting plate 1. Two sliding plates 3 are slidably installed in the rectangular slots 2. The clamping plate 4 is fixedly installed on the bottom of the two sliding plates 3. The two sliding plates 3 are slidably inserted into the interior of the mounting plate 1 through the rectangular slots 2. This can reduce the overall volume of the device and improve the compactness between the structures in the device.

[0032] Each of the two clamping plates 4 has a support plate 5 fixedly installed on the bottom of its opposite side. The support plate 5 is connected to the bottom of the clamping plate 4 by welding, thereby improving the connection strength. The two support plates 5 can support the steel structure profile that is fixedly clamped between the two clamping plates 4, thereby improving the stability of the steel structure profile clamping.

[0033] Multiple hydraulic cylinders 6 are fixedly installed on the top surface of the mounting plate 1 corresponding to the sliding plate 3. Connecting plates 7 are fixedly installed on the top surface of each sliding plate 3. The telescopic ends of the hydraulic cylinders 6 are fixedly connected to the side walls of the connecting plates 7. The hydraulic cylinders 6 can synchronously drive the two connecting plates 7 to move laterally. At the same time, the connecting plates 7 drive the clamping plates 4 fixedly installed thereto to move synchronously. The connecting plates 7 and clamping plates 4 need to be connected by welding to improve the connection strength between the connecting plates 7 and clamping plates 4. Thanks to the structure of hydraulic cylinders 6, sliding plates 3, connecting plates 7 and clamping plates 4, by starting multiple hydraulic cylinders 6, the sliding plates 3 fixedly installed at their telescopic ends are pushed outward, so that the two clamping plates 4 can be separated from each other. Then, the device is placed on both sides of the steel structure to be lifted. At this time, multiple hydraulic cylinders 6 are started again to retract the sliding plates 3 into the rectangular groove 2. The two sliding plates 3 drive the two clamping plates 4 at their bottom to move towards the steel structure and clamp it. At the same time, the two support plates 5 extend to the bottom of the steel structure.

[0034] Two sliding grooves 8 are symmetrically opened on opposite sides of the two clamping plates 4, and abutment plates 9 are slidably installed in multiple sliding grooves 8. A cylinder 10 is fixedly installed on the side of the clamping plate 4 away from the abutment plate 9, and the telescopic end of the cylinder 10 slides into the sliding groove 8 and is fixedly connected to the abutment plate 9. When the clamping plate 4 moves to both sides of the steel structure profile to be clamped, multiple cylinders 10 are activated simultaneously to push the abutment plate 9 fixedly installed at the end of the cylinder 10, and the abutment plate 9 abuts against the surface of the steel structure profile, thereby fixing and clamping the steel structure.

[0035] Multiple arc-shaped grooves are provided on the top surface of both pallets 5. Roller balls 11 are rolled inside the multiple arc-shaped grooves. The bottom of the steel structure will contact the multiple roller balls 11 on the top surface of the pallet 5. When it is necessary to adjust the clamp 4 to the center position of the steel structure, the device can be pushed to move the device under the action of the roller balls 11. The roller balls 11 can reduce the friction between the steel structure and the roller balls 11, which is conducive to the movement of the steel structure.

[0036] Limiting strips 12 are symmetrically fixedly installed on the side walls of multiple sliding plates 3. Strip grooves are symmetrically opened on the inner walls of multiple rectangular grooves 2. The limiting strips 12 fixedly installed on the side walls of the sliding plates 3 are slidably connected to the inside of two strip grooves opened on the inner walls of the rectangular grooves 2. The limiting strips 12 can effectively improve the stability of the sliding plates 3 when sliding.

[0037] Limiting blocks 13 are symmetrically fixedly installed on the side wall of the abutment plate 9. Two limiting grooves are symmetrically opened on the inner wall of the slide groove 8. The two limiting blocks 13 fixedly installed on the side wall of the abutment plate 9 are slidably connected to the inside of the limiting grooves opened on the inner wall of the slide groove 8. The limiting blocks 13 can effectively limit the sliding direction of the abutment plate 9, and can also further improve the stability of the abutment plate 9 when sliding.

[0038] One side of the top surface of the two support plates 5 is inclined, and the inclined surface of the support plates 5 can facilitate the insertion of the support plates 5 into the bottom of the steel structure profile.

[0039] Anti-slip pads 15 are fixedly bonded to the side walls of multiple abutment plates 9. The anti-slip pads 15 can further increase the friction between the abutment plates 9 and the steel structure, thereby further improving the stability of the steel structure.

[0040] Working principle

[0041] When using this steel structure hoisting device, firstly, multiple hydraulic cylinders 6 are activated to push the two clamping plates 4 apart. At this time, the device is lowered to both sides of the steel structure to be hoisted. Then, multiple hydraulic cylinders 6 are activated again, which drives the two clamping plates 4 to move closer together. At the same time, the clamping plates 4 drive the two support plates 5 at their bottom to be inserted into the bottom of the steel structure. The support plates 5 will then lift the steel structure to be hoisted. The bottom of the steel structure will contact multiple ball bearings 11 on the top surface of the support plates 5. If the device needs to be moved, it can be pushed or the steel structure can be pushed. Under the action of the ball bearings 11, the device can be moved easily. Then, multiple air cylinders 10 are activated, which push the abutment plates 9 fixedly installed at their telescopic ends to move towards the steel structure until the two abutment plates 9 squeeze and fix the steel structure. This completes the fixing and clamping of the steel structure.
