Description

Technical Field

[0001] The utility model belongs to the technical field of dam construction equipment, and in particular relates to a dam surface water stop cover plate forming mechanism. Background Art

[0002] At present, face rockfill dams at home and abroad often use V-shaped grooves to embed flexible fillers to waterproof the surface of the joints. The function of the filler is to use water pressure to flow the filler into the seam cavity when the dam body undergoes large settlement and deformation, block the leakage channel, enhance the water-stopping effect of the joints, and improve the safety and reliability of the dam body. In order to protect the filler from the influence of the external environment and prevent the filler from deforming or losing under water pressure, we will set a cover plate outside the filler. This method can effectively improve the waterproof effect of the panel joints and ensure the safety of the project.

[0003] At present, the most widely used method of embedding fillers is manual embedding. However, since most of the flexible fillers sold on the market are rectangular plates or columns and have certain elastic-plastic properties, it is very difficult to carry out manual dense embedding on the dam slope. Especially when the outside temperature is low, the hardness of the filler increases, making the embedding work more difficult. This leads to low efficiency of manual embedding and the embedding quality is not very ideal. Utility Model Content

[0013] Optionally, a mounting seat is provided at the bottom end of the inner rod, and the roller is mounted on the mounting seat.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] One end of the cover plate is fixed on the dam panel in advance, and the filler is squeezed into the V-shaped groove by the filler extrusion device. At the same time, the winding roller rotates under the movement of the trolley to realize automatic laying of the cover plate on the surface of the filler just filled, and a cover plate pressing component with downward telescopic performance is provided.

[0022] A frame 1, with four wheels 2 arranged at the bottom of the frame 1, so that the entire device can be moved on the surface of the dam and has sufficient stability and load-bearing capacity;

[0023] The power device 3 is horizontally installed on the top of the dam and connected to the frame 1 through a traction rope 4 to provide power for the equipment so that the equipment can keep moving smoothly during operation;

[0024] The filler extrusion device is mounted on the frame 1 and is used to extrude the filler into a specific shape and embed it into the V-shaped groove 5. It may include components such as a material box 10, a feeding pump, an extrusion screw 11 and a die head 12 to ensure that the shape of the filler is accurate and the filler extrusion work can be performed efficiently;

[0025] The cover plate forming device is also mounted on the vehicle frame 1 and operates simultaneously with the filler extrusion device. It is used to lay the cover plate 6 on the filler and press the cover plate 6 downward to protect the filler and enhance the water-stopping effect. It may include a coiling roller 13, a cover plate 6 pressing assembly and other components to ensure that the laying and pressing of the cover plate 6 can be stable and reliable.

[0026] Through the above scheme, it is possible to achieve that at the same time as the filler extrusion device is used to fill the seams with filler, the cover plate forming device lays the cover plate 6 on top of the filler and compacts it downwards, thereby realizing the integrated flow operation of filler embedding and cover plate 6 laying; the embedding machine moves and runs uninterruptedly along the seam, the process is simple, and the construction speed and quality are greatly improved.

[0027] In a specific embodiment, the frame 1 is designed to consist of a frame-type chassis 7 and an operating platform 8. The wheels 2 are mounted on the chassis 7 so that the frame 1 can move on the dam slope 9. The chassis 7 is designed to be parallel to the slope of the dam to ensure that the equipment remains stable when moving. The operating platform 8 is fixedly connected to the chassis 7 and parallel to the horizontal plane, providing a stable working platform for operators so that they can easily operate the equipment and perform necessary work. This structural design is intended to improve the operating convenience and stability of the equipment and ensure that the equipment can operate safely and efficiently when working.

[0028] In a specific embodiment, the power device 3 is a winch installed on the horizontal plane of the top of the dam. The winch is connected to the front end of the frame 1 through a traction rope 4. The winch provides power and controls the movement of the frame 1 by adjusting the retraction and release of the rope to ensure that the device can maintain a stable power source and movement trajectory when working. This design allows the power device 3 to be installed on the top of the dam without occupying space on the surface of the dam, while maintaining the convenience and stability of the operation of the device.

[0029] In a specific embodiment, the filler extrusion device includes the following components:

[0030] Material box 10: installed on the operating platform 8, used to store filler. Material box 10 is reasonably designed to facilitate the supply and management of filler.

[0031] Feeding pump: installed at one end of the feeding pipe, used to pump the filler from the material box 10 to the extrusion screw 11.

[0032] Extrusion screw 11: fixed on the base frame 7, parallel to the direction of the traction rope 4. The extrusion screw 11 is provided with a feed port, connected to the material box 10 through a feed pipe, and the lower end is an extrusion port.

[0033] Die head 12: It is installed at the extrusion outlet and is trumpet-shaped. The shape of its outlet is the same as the cross-section of the joint filler to be embedded, so as to ensure the accuracy of the shape of the filler.

[0034] In addition, the design of the filler extrusion device enables the extrusion port to be located above the V-groove, which facilitates the filler to flow directly into the joint, achieving fast, accurate and continuous extrusion of the filler, thereby ensuring uniform distribution and tight filling of the filler in the joint.

[0035] In a further embodiment, the head is designed to be trumpet-shaped, and the shape of its outlet is the same as the cross-section of the joint filler to be embedded. This means that the design of the die head 12 is customized according to the shape and size of the joint filler, ensuring that the filler can form a shape that matches the cross-section of the joint when it is extruded. With this design, the filler can fill the joint more accurately when it is extruded, ensuring the uniformity and tightness of the filler, thereby improving the water-stopping effect and the safety of the project.

[0036] In a further embodiment, a heating device is also provided on the extrusion screw 11. This heating device can be a heating tube or a heating coil, etc., and their function is to heat the filler to an appropriate temperature by heating the extrusion screw 11, so that the filler is softer and easier to extrude during the extrusion process. Heating the filler can reduce the viscosity of the filler, increase the fluidity of the filler, and help the filler to better fill the joints during the extrusion process, ensuring the uniform distribution and tight filling of the filler. At the same time, heating can also improve the fluidity of the filler, reduce the resistance of the filler during the extrusion process, and further improve the efficiency and quality of the filler extrusion. Therefore, providing a heating device on the extrusion screw 11 can effectively improve the extrusion performance of the filler, improve the working efficiency of the equipment and the use effect of the filler. .

[0040] Guide column 15: It is fixed horizontally on the operating platform 8 and is used to prevent the cover plate 6 from contacting the extrusion screw 11 to avoid unnecessary friction and damage.

[0041] One end of the cover plate is fixed on the dam panel in advance, and the filler is squeezed into the V-shaped groove by the filler extrusion device. At the same time, the winding roller rotates under the movement of the trolley to realize automatic laying of the cover plate on the surface of the filler just filled, and a cover plate pressing component with downward telescopic performance is provided. The pressure wheel presses the two side edges of the cover plate downward under the action of the compression spring to ensure a good seal between the cover plate 6 and the filler.
