Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic climbing formwork devices, and specifically relates to a hydraulic climbing formwork device for steel formwork. Background Technique

[0002] The climbing formwork device is attached to the concrete structure through a carrier. When the newly poured concrete is demolded and the concrete strength at the force-bearing part of the carrier reaches 10 MPa, the climbing formwork device is lifted up one layer with the hydraulic cylinder as the power and the guide rail as the climbing track. Such a construction process of repeated cyclic operation is simply called climbing formwork.

[0003] In the existing hydraulic climbing formwork device, it is fixed to the climbing formwork frame. The climbing formwork frame is self-locked and slidably assembled with the building by using the guide rail. The hydraulic climbing formwork device uses a clamping part to gradually clamp and lift the steel frame rail, then move down and extend, clamp and lift again, and so on to complete the climbing formwork work. However, the steel frame is only fixedly clamped and lifted by the clamping device. When the upper end of the steel frame does not contact the upper fixed node, only the lower node supports the steel frame, with single-point support. When the steel frame is lifted by climbing formwork, it is very likely that the upper end of the steel frame will shift, thus affecting the climbing formwork work and making it difficult for the steel frame to be accurately aligned with the upper node.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a hydraulic climbing formwork device for steel formwork is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hydraulic climbing formwork device for steel formwork to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hydraulic climbing formwork device for steel formwork, including a fixing part, a limiting plate is fixedly installed on the upper surface of the fixing part, sliding grooves are respectively opened at the left and right ends of the inner surface of the limiting plate, a spring is fixedly installed on the inner surface of the sliding groove, a slider is fixedly installed at one end of the spring close to the middle of the limiting plate, the slider slides inside the sliding groove, and a rubber roller is rotatably installed on the opposite side in the horizontal direction of the slider, and the rubber roller protrudes from the inner surface of the limiting plate.

[0007] Preferably, a hydraulic telescopic rod is fixedly installed at the lower end of the fixing part, and a positioning frame is fixedly installed at the lower end of the hydraulic telescopic rod.

[0008] Preferably, a steel frame slides through the right side inside the positioning frame, and a clamping mechanism is installed on the lower surface of the positioning frame.

[0009] Preferably, the clamping mechanism includes a fixing frame fixedly installed on the left side of the lower surface of the positioning frame, and a guiding rod is fixedly installed at the right end inside the fixing frame.

[0010] Preferably, the clamping mechanism further includes a telescopic cylinder fixedly arranged through the left side of the fixed frame surface, and a connecting plate is fixedly arranged at the right end of the telescopic cylinder.

[0011] Preferably, the clamping mechanism further includes movable rods rotatably connected to the middle parts of the front and rear sides of the connecting plate. Clamping plates are rotatably connected to the right ends of the movable rods, and the clamping plates are slidably sleeved on the surface of the guiding rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the settings of the limiting plate, sliding groove, spring, slider and rubber roller in the present utility model, when the steel frame climbs, the upper part of the steel frame will be limited by the limiting plate to prevent the upper end of the steel frame from shifting. At the same time, the front and rear sides of the steel frame will come into contact with the rubber roller first. The rotation of the rubber roller will reduce the frictional force of the steel frame moving upward and prevent the steel frame from being worn. At the same time, the rubber roller slides inside the sliding groove by squeezing the spring with the slider, which can adjust the space inside the limiting plate to adapt to steel frames of different widths, greatly improving the climbing stability of the steel frame and enhancing the adaptability of the limiting plate to the steel frame, and significantly increasing the flexibility of use;

[0014] 2. Through the settings of the clamping mechanism, fixed frame, guiding rod, telescopic cylinder, connecting plate, movable rod and clamping plate in the present utility model, the steel frame passes through the middle of the clamping plate. When the telescopic cylinder contracts, it contracts to the left through the connecting plate and the movable rod. Under the limitation of the guiding rod, the clamping plate will be pulled to move towards the middle, thereby clamping the steel frame. Then, by contracting the hydraulic telescopic rod, the steel frame can be pulled upward to complete the climbing work. The clamping method is simple and reliable, easy to maintain, and the clamping force is transmitted in a way that avoids the direct contact between the clamping force generating part and the steel frame, preventing the surface of the steel frame from being sunken and deformed due to excessive force.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] As Figures 1 - 3 shown, a hydraulic climbing formwork device for steel formwork includes a fixing piece 1. A limiting plate 2 is fixedly installed on the upper surface of the fixing piece 1. Sliding grooves 3 are respectively opened at the left and right ends of the inner surface of the limiting plate 2. A spring 4 is fixedly installed on the inner surface of the sliding groove 3. One end of the spring 4 close to the middle of the limiting plate 2 is fixedly installed with a slider 5. The slider 5 slides inside the sliding groove 3. A rubber roller 6 is rotatably installed on the opposite side in the horizontal direction of the slider 5. The rubber roller 6 protrudes from the inner surface of the limiting plate 2.

[0022] By adopting the above technical solutions, when the steel frame 9 climbs, the upper part of the steel frame 9 will be limited by the limiting plate 2 to prevent the upper end of the steel frame 9 from shifting; the front and rear sides of the steel frame 9 will come into contact with the rubber roller 6 first. The rotation of the rubber roller 6 will reduce the frictional force of the steel frame 9 during upward climbing and prevent the steel frame 9 from being worn; the rubber roller 6 uses the slider 5 to squeeze the spring 4 and slide inside the sliding groove 3, which can adjust the space inside the limiting plate 2 to adapt to steel frames 9 of different widths.

[0023] Furthermore, a hydraulic telescopic rod 7 is fixedly installed at the lower end of the fixing piece 1. A positioning frame 8 is fixedly installed at the lower end of the hydraulic telescopic rod 7;

[0024] The steel frame 9 is slidably penetrated through the right side inside the positioning frame 8. A clamping mechanism 10 is installed on the lower surface of the positioning frame 8.

[0025] By adopting the above technical solutions, the positioning frame 8 limits the insertion position of the steel frame 9; the hydraulic telescopic rod 7 can pull the clamping mechanism 10 upward through the positioning frame 8 to complete the climbing operation.

[0026] As Figure 1 and Figure 4 shown, the clamping mechanism 10 includes a fixing frame 1001 fixedly installed on the left side of the lower surface of the positioning frame 8. A guiding rod 1002 is fixedly installed at the right end inside the fixing frame 1001.

[0027] By adopting the above technical solution, the fixing frame 1001 provides an installation and connection assembly position for the entire clamping mechanism 10 .

[0028] Furthermore, the clamping mechanism 10 also includes a telescopic cylinder 1003 that passes through and is fixedly arranged on the left side of the surface of the fixing frame 1001 , and a connecting plate 1004 is fixedly arranged on the right end of the telescopic cylinder 1003 .

[0029] By adopting the above technical solution, the telescopic cylinder 1003 can drive the connecting plate 1004 to move left and right.

[0030] Furthermore, the clamping mechanism 10 also includes a movable rod 1005 rotatably connected to the middle of the front and rear sides of the connecting plate 1004 , and a clamping plate 1006 rotatably connected to the right end of the movable rod 1005 , which is slidably sleeved on the surface of the guide rod 1002 .

[0031] By adopting the above technical solution, the connecting plate 1004 moves, and the movable rod 1005 is used to move the clamping plate 1006, while the guide rod 1002 limits the moving direction of the clamping plate 1006, so that the clamping plate 1006 can only move along the guide rod 1002.

[0032] Working principle: When using the hydraulic climbing formwork device for steel formwork, first, the steel frame 9 is connected by the first fixed slide rail node on the building, and the connection position corresponds to the middle of the clamping plate 1006, and also corresponds to the middle position of the positioning frame 8, to ensure that the entire hydraulic climbing formwork device is accurate with the steel frame 9 and the building climbing point. Then, the telescopic cylinder 1003 contracts and contracts to the left through the connecting plate 1004 and the movable rod 1005. Under the limit of the guide rod 1002, the clamping plate 1006 will be pulled to move to the middle, thereby clamping the steel frame 9. Then, by contracting the hydraulic telescopic rod 7, the steel frame 9 can be pulled up, so that the hydraulic telescopic The rod 7 moves up and down reciprocatingly, and the clamping mechanism 10 closes and opens reciprocatingly to complete the climbing work. When the steel frame 9 is climbing, the upper part of the steel frame 9 will be limited by the limit plate 2 to prevent the upper end of the steel frame 9 from shifting. At the same time, the front and rear sides of the steel frame 9 will preferentially contact the rubber roller 6. The rotation of the rubber roller 6 will reduce the friction of the steel frame 9 climbing up and prevent the steel frame 9 from being worn. At the same time, the rubber roller 6 uses the slider 5 to squeeze the spring 4 to slide inside the slide groove 3, and the space inside the limit plate 2 can be adjusted to adapt to steel frames 9 of different widths until the upper end of the steel frame 9 is connected with the second fixed slide rail node of the upper layer of the building. This is the working principle of the hydraulic climbing formwork device for steel formwork.
