Description

Technical Field

[0001] This utility model application relates to the technical field of lifting tools, and specifically relates to a U-shaped rib integral lifting tool. Background Art

[0002] U-shaped ribs are usually used on the sides of raft slabs to enhance the structural stability and bearing capacity. In addition, U-shaped ribs can also be used for the end bending of cantilever beams to adapt to the required shape of the design and ensure the integrity and safety of the structure. In architectural design and construction, the correct use of U-shaped ribs is crucial for improving the overall performance of building structures.

[0003] During the installation and construction of traditional U-shaped ribs, most of them are first bent into shape one by one, and then the steel bars are placed at the steel bar layout settings of the box girder steel cage frame. The method of placing them one by one has the problem of large errors in the placement of steel bars during the processing, which is not conducive to the subsequent binding of the steel cage. Therefore, a U-shaped rib integral lifting tool is proposed. Summary of the Invention

[0004] In order to solve the problem that the existing U-shaped ribs are relatively cumbersome to arrange and place individually during construction and installation, this utility model provides a U-shaped rib integral lifting tool to solve the above problems.

[0005] To achieve the above object, this utility model provides the following technical solution: A U-shaped rib integral lifting tool includes a shaping bracket, and limiting side brackets are arranged on both sides of the shaping bracket for positioning the U-shaped ribs. Clamping components are arranged at the upper and lower ends on both sides of the limiting side brackets and at the bottom of the shaping bracket.

[0006] The clamping component includes a fixed clamping plate, a fixed clamping groove and a fixed clamping block. Fixed clamping plates are fixed at the bottom ends of both ends of the shaping bracket and at the upper and lower ends of the limiting side brackets, and upper control rockers matched with the U-shaped ribs are arranged on the outer sides of the fixed clamping plates. A support rod is fixed on the side of each fixed clamping groove, and a fixed clamping block is rotatably sleeved on the support rod. One end of the fixed clamping block away from the fixed clamping groove is rotatably sleeved on a connecting rod, and the connecting rods are all fixed on a pulling plate. Limiting plates are slidably arranged on both sides of the pulling plate, and the limiting plates are fixed on the shaping bracket or the limiting side bracket.

The connecting chain between the guide wheels at both ends is connected by a pulling rope. The connecting chains at the bottom of the shaping bracket and the two limiting side brackets are controlled by an upper control rocker and a lower control rocker respectively.

[0007] Furthermore, the shaping bracket and the limiting side brackets are both arranged in a U shape matched with the U-shaped ribs. The pulling ropes and guide wheels on both sides of the shaping bracket and the limiting side brackets cooperate with the pulling plate to form a rectangular closed loop.

[0008] Further, one end of each of the fixed clamping blocks away from the connecting rod and the fixed clamping groove are both set to be arc-shaped to cooperate with the U-shaped ribs, and each of the fixed clamping blocks is movably connected inside the fixed clamping plate.

[0009] Further, the tops of the two guide wheels of the shaping bracket are fixed by a pulling rope, the bottoms of the two guide wheels above the limiting side frame are both fixed with a pulling rope, and the bottoms of the pulling ropes are both fixed with another guide wheel.

[0010] Further, the two other guide wheels are both meshingly sleeved on the two lower connecting chains, and the connecting chains are rotatably connected to the shaping bracket or the limiting side frame through bearings. The relative ends of the two guide wheels are also fixedly connected by a pulling rope.

[0011] Further, a guide sleeve is slidably sleeved outside each of the pulling ropes, and the guide sleeves are respectively fixed on the shaping bracket and the limiting side frame. Two evenly distributed guide sleeves are sleeved on each of the pulling ropes.

[0012] Further, the upper control rocker and the lower control rocker both penetrate and are fixed at the central position on the side of the connecting chain, and the upper control rocker and the lower control rocker are respectively rotatably connected to the limiting side frame or the shaping bracket.

[0013] Further, locking cylinders are arranged on the sides of the upper control rocker and the lower control rocker, and a pressing block that cooperates with the outer surfaces of the upper control rocker and the lower control rocker is fixed at the output end of the locking cylinder.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, the U-shaped ribs are first arranged and positioned by the positioning side frame, and then the U-shaped ribs are clamped by the cooperation of the fixed clamping groove and the fixed clamping block. After transporting them to the installation position, the fixed clamping block is opened, and the U-shaped ribs can be accurately placed into the installation position of the box girder steel reinforcement cage, ensuring the accuracy of the U-shaped ribs during construction and installation.

Detailed implementation manners

[0024] To make the application purpose, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0025] Referring to Figure 1 , Figure 2 and Figure 3 , a U-shaped rib integral sling includes a sizing bracket 1, and limiting side frames 2 are arranged on both sides of the sizing bracket 1 for positioning the U-shaped rib. Clamping assemblies are arranged at the upper and lower ends on both sides of the limiting side frames 2 and at the bottom of the sizing bracket 1;

[0026] The clamping assembly includes a fixed clamping plate 3, a fixed clamping groove 4, and a fixed clamping block 5. Fixed clamping plates 3 are fixed to the bottom ends of both sides of the shaping bracket 1 and the upper and lower ends of the limiting side frame 2. Upper control rockers 14 that cooperate with the U-shaped ribs are provided on the outer sides of the fixed clamping plates 3. A support rod 6 is fixed to the side of each fixed clamping groove 4, and a fixed clamping block 5 is rotatably sleeved on the support rod 6. One end of the fixed clamping block 5 away from the fixed clamping groove 4 is rotatably sleeved on the connecting rod 8, and the connecting rods 8 are fixed to the pulling plate 9. Limiting plates 7 are slidably arranged on both sides of the pulling plate 9, and the limiting plates 7 are fixed to the shaping bracket 1 or the limiting side frame 2. Guide wheels 13 are fixed to both ends of each pulling plate 9, and the guide wheels 13 are meshingly sleeved on the connecting chain 10. The guide wheels 13 at both ends are connected by a pulling rope 11.

[0027] Specifically, the shaping bracket 1 and the limiting side frame 2 are both arranged in a U-shape that cooperates with the U-shaped rib. The pulling ropes 11 and the guide wheels 13 on both sides of the shaping bracket 1 and the limiting side frame 2 cooperate with the pulling plate 9 to form a rectangular closed loop, which is convenient for the guide wheels 13 and the guide sleeve 12 to move forward to drive the pulling plate 9 to move towards one side when moving, thereby driving the fixed clamping block 5 to rotate. One end of each fixed clamping block 5 away from the connecting rod 8 and the fixed clamping groove 4 are both arranged in an arc shape that cooperates with the U-shaped rib. Each fixed clamping block 5 is movably connected inside the fixed clamping plate 3, which is convenient for the fixed clamping block 5 to clamp the U-shaped rib.

[0028] As an optimized solution, as Figure 3 and Figure 4 shown, the pulling ropes 11 are fixed between the tops of the two guide wheels 13 of the shaping bracket 1. Pulling ropes 11 are fixed to the bottoms of the two guide wheels 13 above the limiting side frame 2. Another guide wheel 13 is fixed to the bottom of each pulling rope 11. The two other guide wheels 13 are meshingly sleeved on the two connecting chains 10 below, and the connecting chains 10 are rotatably connected to the shaping bracket 1 or the limiting side frame 2 through bearings. The pulling ropes 11 are also fixedly connected between the opposite ends of the two guide wheels 13. A guide sleeve 12 is slidably sleeved on the outside of each pulling rope 11, and the guide sleeves 12 are respectively fixed to the shaping bracket 1 and the limiting side frame 2. Two guide sleeves 12 are evenly distributed on each pulling rope 11. The connecting chains 10 at the bottom of the shaping bracket 1 and the two limiting side frames 2 are respectively controlled by the upper control rocker 14 and the lower control rocker 15.

[0029] Specifically, both the upper control rocker 14 and the lower control rocker 15 penetrate and are fixed at the central position on the side of the connecting chain 10. The upper control rocker 14 and the lower control rocker 15 are respectively rotatably connected to the limit side frame 2 or the shaping bracket 1. Locking cylinders are arranged on the sides of the upper control rocker 14 and the lower control rocker 15, and a pressing block that cooperates with the outer surfaces of the upper control rocker 14 and the lower control rocker 15 is fixed at the output end of the locking cylinder, which facilitates rotating the upper control rocker 14 and the lower control rocker 15 to drive the connecting chain 10 to rotate. The connecting chain 10 drives the guide wheel 13 to move, so as to control the fixed clamp 5 to rotate and clamp the U-shaped rib through the pulling plate 9.

[0030] Working principle: When the lifting tool is needed, arrange the U-shaped ribs one by one inside the limit side frame 2. After being supported and positioned by the limit side frame 2 and the shaping bracket 1, at this time, the U-shaped ribs are engaged inside the fixed card slot 4. Then rotate the upper control rocker 14 and the lower control rocker 15 respectively, so that the upper control rocker 14 and the lower control rocker 15 drive the connecting chain 10 to rotate. When the connecting chain 10 rotates, its teeth drive the guide wheel 13 engaged with the upper control rocker 14 to move. When the guide wheel 13 moves, it drives the pulling rope 11 to slide inside the guide sleeve 12. At the same time, the pulling rope 11 and the guide wheel 13 as a whole move to one side, driving the pulling plate 9 to move. The movement of the pulling plate 9 can push the fixed clamp 5 to rotate. When the fixed clamp 5 rotates to the side of the fixed card slot 4 to clamp the U-shaped rib, the U-shaped rib can be fixed on the shaping bracket 1. Move the shaping bracket 1, and the position of the U-shaped rib can be moved. After the adjustment is completed, control the upper control rocker 14 and the lower control rocker 15 to rotate in the reverse direction, which can drive the connecting chain 10 to rotate in the reverse direction, thereby driving the pulling plate 9 to move in the reverse direction and pushing the fixed clamp 5 to rotate away from the fixed card slot 4, so that the fixed card slot 4 can be opened. At this time, the fixation of the U-shaped rib is released, and the U-shaped rib can be removed from the shaping bracket 1 and the limit side frame 2. When adjusting the upper control rocker 14 and the lower control rocker 15, the locking cylinder drives the pressing block away from the upper control rocker 14 and the lower control rocker 15. After the adjustment is completed, the locking cylinder pushes the pressing block to abut against the upper control rocker 14 and the lower control rocker 15 to lock the upper control rocker 14 and the lower control rocker 15.
