Description

Technical Field

[0001] This utility model relates to the field of climbing formwork fall prevention technology, and in particular to a hydraulic climbing formwork climbing guide rail fall prevention device. Background Technology

[0002] Climbing formwork, also known as scaffolding formwork internationally, consists of three parts: climbing formwork, climbing scaffolding (some climbing formwork systems do not have climbing scaffolding), and climbing equipment. It is an effective tool in the construction of tall structures such as shear wall systems, cylindrical tube systems, and bridge piers. Due to its self-climbing capability, it eliminates the need for lifting machinery, reducing the workload of transport equipment during construction. Suspending scaffolding on the self-climbing formwork eliminates the need for external scaffolding during construction. In summary, climbing formwork reduces the number of lifting machines required and speeds up construction, thus offering good economic benefits.

[0003] A search revealed a climbing formwork safety fall arrest device (publication number CN221194215U), comprising a climbing formwork wall, a climbing frame, a protective plate, and a fall arrest component. A climbing frame is installed at one end of the climbing formwork wall, and scaffolding is correspondingly connected to one end of the climbing frame. The fall arrest component is installed at the lower end of the scaffolding. A protective plate is installed on one side of the climbing frame, and a connecting plate is detachably installed at one end of the climbing frame. This application utilizes a climbing frame installed at one end of the climbing formwork wall and a protective plate on one side of the climbing frame to protect the climbing frame structure during upward climbing, preventing damage from external factors and avoiding jamming during ascent, ensuring normal use of the climbing frame. The fall arrest component at the lower end of the scaffolding intercepts any loose parts that may fall during use.

[0004] In the aforementioned existing technical solutions, the fall arrestor was not designed with the potential for collision between the scaffolding and the fall arrestor frame during the climbing operation in mind. Since the scaffolding needs to be in close contact with the fall arrestor frame during the climbing process, and without a buffer device, a collision between the scaffolding and the fall arrestor frame could result in significant impact on the frame, thus affecting its stability and functionality.

[0005] Therefore, we propose a hydraulic climbing formwork climbing guide rail anti-fall device. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a hydraulic climbing formwork climbing guide rail anti-fall device.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic climbing formwork climbing guide rail anti-fall device, comprising a climbing formwork wall, a slide groove, a positioning groove, an anti-fall plate, and scaffolding. A slide rail is installed in the slide groove, and a slider slides on the slide rail. A positioning block is provided in the positioning groove, and a shock-absorbing sleeve is fixed at the bottom of the positioning block. A spring is fixed in the inner cavity of the shock-absorbing sleeve, and a shock-absorbing rod slides in the shock-absorbing sleeve. A buffer sleeve is fixed at the bottom of the shock-absorbing rod, and a buffer rod is sleeved in the inner cavity of the buffer sleeve. A spring is fixed in the inner cavity of the buffer sleeve, and a buffer slider is slidably connected to the buffer rod. A spring is sleeved on the buffer rod.

[0008] Preferably, limit grooves are provided on both side walls of the inner cavity of the buffer sleeve, and limit sliders are fixedly connected to both sides of the top of the buffer sleeve rod.

[0009] Preferably, the limiting slider and the limiting groove are adapted to each other, and the limiting slider is limited in the inner cavity of the limiting groove.

[0010] Preferably, the top of the shock-absorbing sleeve is fixedly connected to the other end of the spring.

[0011] Preferably, the other end of the spring three is fixed to the top wall of the buffer sleeve rod.

[0012] Preferably, the second spring is located below the buffer slider.

[0013] This utility model provides a fall prevention device for a hydraulic climbing formwork guide rail. It has the following beneficial effects:

[0014] 1. This hydraulic climbing formwork climbing guide rail anti-fall device initially reduces shock through the cooperation of a shock-absorbing sleeve and a spring, and then buffers the impact force of the scaffolding through the cooperation of a buffer sleeve and a spring. Furthermore, the buffer sleeve continuously compresses the buffer slider, which compresses the spring and further buffers the impact force of the scaffolding, thereby reducing the impact on the anti-fall frame and improving its stability and functionality.

[0015] 2. This hydraulic climbing formwork climbing guide rail anti-fall device, through the cooperation of the limiting slider and the limiting groove, makes the buffer sleeve rod limited in the inner cavity of the buffer sleeve, so as to avoid falling off and improve the stability of the device.

[0025] Example: A hydraulic climbing formwork climbing guide rail anti-fall device, such as... Figures 1-4As shown, the climbing formwork wall 1 includes a sliding groove 101 and a positioning groove 102 on both sides of the climbing formwork wall 1. A slide rail 2 is installed in the inner cavity of the sliding groove 101, and a slider 201 is slidably connected to the slide rail 2. A positioning block 3 is provided in the inner cavity of the positioning groove 102 at a position corresponding to the slider 201. Scaffolding 104 is installed on the wall surface of the slider 201 and the positioning block 3. A fall arrestor 103 is installed on the side wall of the climbing formwork wall 1 below the scaffolding 104. A shock-absorbing sleeve 4 is fixedly connected to the bottom of the positioning block 3. A spring 401 is fixedly connected to the inner cavity of the shock-absorbing sleeve 4. A shock-absorbing rod 5 is slidably connected to the inner cavity of the shock-absorbing sleeve 4. The top of the shock-absorbing rod 5 is fixedly connected to the other end of the spring 401. A buffer sleeve 6 is fixedly connected to the bottom of the shock-absorbing sleeve rod 5. A buffer sleeve rod 7 is fitted inside the cavity of the buffer sleeve 6. Limiting grooves 601 are opened on both side walls of the inner cavity of the buffer sleeve 6. Limiting sliders 703 are fixedly connected to both sides of the top of the buffer sleeve rod 7 at positions corresponding to the limiting grooves 601. The limiting sliders 703 and the limiting grooves 601 are mutually adapted and the limiting sliders 703 are limited in the inner cavity of the limiting grooves 601. A spring 3 8 is fixedly connected to the inner cavity of the buffer sleeve 6. The other end of the spring 3 8 is fixed to the top wall of the buffer sleeve rod 7. A buffer slider 701 is slidably connected to the buffer sleeve rod 7. A spring 2 702 is fitted on the buffer sleeve rod 7 below the buffer slider 701.

[0026] The working principle of this utility model:

[0027] When the scaffold 104 moves downwards towards the fall arrestor 103, the positioning block 3 compresses the spring 401 in the inner cavity of the shock-absorbing sleeve 4 downwards, and continues to buffer the impact force of the scaffold 104 through the spring 8 in the inner cavity of the buffer sleeve 6. The buffer sleeve 6 continuously compresses the buffer slider 701, which compresses the spring 702, and the spring 702 buffers the impact force of the scaffold 104 again.
