Description

Technical Field

[0001] This utility model relates to the field of installation tool technology, specifically a tool for installing rubber dams. Background Technology

[0002] Rubber dams, as a new type of hydraulic structure, have been widely used in water conservancy projects due to their significant advantages of low cost, short construction period, and good seismic performance. They have become important facilities in river management, water resource regulation, and water landscape construction. Currently, with the expansion of water conservancy projects and technological upgrades, rubber dams are rapidly developing towards larger and lighter sizes. The length of a single dam section can reach tens of meters, and the weight can reach several tons. Moreover, the surface rubber layer is soft and has weak damage resistance, making it extremely susceptible to irreversible damage from scratches and tears during hoisting. This poses three core challenges to the load-bearing capacity, clamping stability, and damage prevention performance of hoisting tools.

[0003] Water conservancy project construction sites are mostly located in special areas such as river channels and tidal flats, with harsh and variable terrain conditions: In riverbank areas, the terrain is steep, making it difficult for cranes and other lifting equipment to find stable parking points, which can easily lead to slippage and uneven stress on the dam body during lifting, seriously affecting the positioning accuracy; In tidal flat areas, the soil has high water content and low bearing capacity, and equipment is prone to sinking into the mud after entering. Even with auxiliary measures such as laying steel plates, it is difficult to completely prevent equipment settlement, often leading to work interruptions; In addition, existing buildings, trees, rocks and other obstacles at the construction site can significantly limit the operating range and movement path of lifting equipment. It is difficult to adjust the lifting angle in narrow spaces, further increasing the risk of friction and compression with obstacles during the lifting and transportation of the dam body. Therefore, it is essential to develop specialized lifting tools. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to provide a tool for installing rubber dams.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tool for installing a rubber dam, comprising: Two steel frames are provided, with concrete bases fixedly connected to the bottom of each steel frame. Two cables are installed at the top of the two steel frames, with anti-friction components between the cables and the steel frames. Concrete anchor seats are fixedly connected to both ends of each cable.

[0006] A steel wire rope is provided at the bottom of the cable, and a traction component is provided between the steel wire rope and the cable. A mechanical clamping device is fixedly connected to the bottom end of the cable. A buffer pad is provided on the inner side of each of the two clamping arms of the mechanical clamping device. A disassembly and assembly component is provided between the buffer pad and the clamping arms of the mechanical clamping device.

[0007] In a preferred embodiment of the present invention, the anti-friction component includes two mounting blocks fixed to the top of the steel frame, and an I-shaped pulley is rotatably connected between the two mounting blocks.

[0008] In a preferred embodiment of this utility model, the cable portion is placed in the middle of the I-shaped pulley on the same side.

[0009] In a preferred embodiment of the rubber dam installation tool provided by this utility model, the traction component includes a U-shaped frame placed at the bottom of the cable, and an I-shaped pulley is rotatably connected to the top of the inner side wall of the U-shaped frame.

[0010] In a preferred embodiment of this utility model, the cable is placed between the I-shaped pulley and the U-shaped frame.

[0011] In a preferred embodiment of this utility model, the disassembly component includes multiple threaded holes formed on the inner wall of the clamping arm of the mechanical clamping device, and multiple screws are inserted on the buffer pad, with the screws threadedly connected to the inner wall of the threaded holes.

[0012] In a preferred embodiment of this utility model, the cushioning pad is made of a soft and elastic material.

[0013] In a preferred embodiment of this utility model, the cushioning pad is made of rubber or polyurethane.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a tool for installing rubber dams. It forms a stable support system through two steel frames, a concrete base fixed at the bottom, and concrete anchors connecting both ends of the cable. This effectively resists the risk of equipment slippage in riverbank areas and the problem of equipment settlement in tidal flat areas, providing a reliable foundation for hoisting operations. It solves the problem of instability caused by harsh terrain in traditional hoisting methods. The anti-friction component between the cable and the steel frame, consisting of an installation block and an I-shaped pulley, transforms the hard friction between them into rolling friction, significantly reducing cable wear and extending component life. Furthermore, placing the cable in the middle of the I-shaped pulley ensures balanced force distribution, avoiding safety hazards caused by localized stress concentration. The traction component between the wire rope and the cable, consisting of a U-shaped frame and an I-shaped pulley, allows for smoother wire rope movement through the smooth rotation of the I-shaped pulley, preventing... Stuttering affects hoisting accuracy. To help the dam body be accurately positioned in narrow, obstacle-filled sites, the rubber or polyurethane buffer pads on the inner side of the mechanical clamping arms effectively isolate the clamping force from the direct action on the rubber dam surface, avoiding scratches and compression damage. The detachable design of the buffer pad and clamping arms through threaded holes and screws allows for flexible replacement of the buffer pad according to the surface characteristics of different rubber dams, improving the tool's adaptability to small to large rubber dams. The overall structure combines wind load resistance and component weather resistance, enabling continuous operation in windy, humid, and dusty construction sites, reducing work interruptions caused by environmental factors. This not only reduces the equipment procurement costs for construction units by adapting one tool to multiple working conditions, but also fundamentally improves the safety, efficiency, and accuracy of rubber dam installation, effectively ensuring the progress of water conservancy project construction and the quality of dam installation.

Detailed Implementation

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a tool for installing a rubber dam, including two steel frames 1, which serve as the core support skeleton of the tool. Their main function is to bear the weight of the entire hoisting system. The bottom end of the steel frame 1 is fixedly connected to a concrete base 2, which increases the contact area between the steel frame 1 and the ground and improves the overall support's resistance to overturning and settlement. Two cables 3 are installed at the top of the two steel frames 1, which bear the longitudinal load and transmit force. One end is connected to the top of the steel frame 1 through an anti-friction component 4, and the other end is fixed to a concrete anchor seat 5, forming a span-type hoisting support structure. Its flexible and high-strength characteristics can adapt to the span requirements of different construction sites. At the same time, it transmits the hoisting power of the crane to the mechanical clamping device 8, ensuring that the rubber dam is stable under force during hoisting and transportation, and avoiding local stress concentration caused by rigid connection. An anti-friction component 4 is installed between the cable 3 and the steel frame 1. Both ends of the cable 3 are fixedly connected to concrete anchor seats 5, which anchor the cable 3 at the ends and enhance the pull-out resistance and stability of the overall hoisting system. A steel wire rope 6 is installed at the bottom of the cable 3 to transmit hoisting power and bear the direct weight of the rubber dam. Its high strength and tensile strength characteristics can meet the hoisting requirements of rubber dams weighing several tons. A traction component 7 is installed between the steel wire rope 6 and the cable 3. A mechanical clamping device 8 is fixedly connected to the bottom end of the cable 3 to directly clamp the rubber dam. It is a key component to ensure the stability of the dam hoisting. It is an adjustable device that can adapt to the clamping requirements of rubber dams of different sizes. The inner sides of the two clamping arms of the mechanical clamping device 8 are equipped with buffer pads 9. The buffer pads 9 are made of soft and elastic materials, such as rubber or polyurethane, to protect the surface of the rubber dam from damage. Its elasticity can isolate the rigid clamping force of the clamping arms of the mechanical clamping device 8, avoiding the clamping arms from directly contacting the dam surface and causing scratches, squeezing deformation or tearing. At the same time, it increases the contact area with the dam through slight deformation, further improving the clamping stability. A disassembly and assembly part 10 is installed between the buffer pads 9 and the clamping arms of the mechanical clamping device 8.

[0020] The anti-friction component 4 includes two mounting blocks 41 fixed to the top of the steel frame 1. An I-shaped pulley 42 is rotatably connected between the two mounting blocks 41, which converts the hard sliding friction between the cable 3 and the steel frame 1 into rolling friction of the pulley, greatly reducing the wear of the cable 3 and extending its service life. Part of the cable 3 is placed in the middle of the I-shaped pulley 42 on the same side.

[0021] The traction component 7 includes a U-shaped frame 71 placed at the bottom of the cable 3. The top of the inner wall of the U-shaped frame 71 is rotatably connected to an I-shaped pulley 72. The cable 3 is placed between the I-shaped pulley 72 and the U-shaped frame 71. The I-shaped pulley 72 is locked onto the cable 3, which guides the movement direction of the wire rope 6, reduces the wear of the wire rope 6, and improves the hoisting accuracy.

[0022] The detachable component 10 includes multiple threaded holes 101 formed on the inner side wall of the clamping arm of the mechanical clamping device 8, and multiple screws 102 inserted on the buffer pad 9. The screws 102 are threadedly connected to the inner wall of the threaded holes 101, so as to realize the detachable connection between the buffer pad 9 and the mechanical clamping device 8.

[0023] The usage process of the rubber dam installation tools described in this embodiment is as follows: Before the rubber dam installation, two steel frames 1 are securely installed on the construction site via concrete bases 2 fixed at their bottom ends. Simultaneously, both ends of the cable 3 are connected and anchored to concrete anchor seats 5. The cable 3 is then spanned by an I-shaped pulley 42 supported by the mounting block 41 of the anti-friction component 4 at the top of the steel frame 1, forming a stable support system. The concrete bases 2 and concrete anchor seats 5, relying on their own weight and ground adhesion, effectively resist the risk of equipment slippage on the riverbank slope and the equipment settlement problem in the tidal flat area. The I-shaped pulley 42 converts the hard sliding friction between the cable 3 and the steel frame 1 into rolling friction. The cable 3 is reduced in wear and its force is balanced. During operation, the wire rope 6 moves smoothly under the guidance of the U-shaped frame 71 and the I-shaped pulley 72 of the traction component 7. The smooth rotation of the I-shaped pulley 72 avoids jamming of the wire rope 6 and ensures that the power is accurately transmitted to the mechanical clamping device 8 at the bottom of the cable 3. Then, the mechanical clamping device 8 clamps the rubber dam with the adjustable clamping arm. The rubber or polyurethane buffer pad 9 on the inside of the clamping arm can isolate the rigid clamping force of the clamping arm and prevent scratches, squeezing deformation or tearing on the surface of the dam. At the same time, the slight deformation of the buffer pad 9 can increase the contact area with the dam and further improve the clamping stability.
