Technical Field

[0001] The utility model relates to the technical field of plastic connection, in particular to an automatic pressing device for waterproof coiled material joint anti-scouring plates. Background Art

[0002] The purpose of laminating the anti-scouring board at the joints of waterproof membranes is to enhance the durability and waterproof reliability of the joints. In places such as water conservancy projects, underground structures or roofs that are subject to long-term water scouring or environmental erosion, the joints of traditional membranes are prone to peeling and leakage due to water flow impact, temperature deformation or mechanical stress. The anti-scouring board disperses the impact of water flow through a rigid protective layer of metal or polymer materials. It is particularly suitable for high water pressure environments such as reservoirs and tunnels. It is a key technical measure to improve the overall reliability of the waterproof system.

[0003] The existing pressing method is mostly manual operation. The operator needs to first apply polyurethane base treatment agent on the joints of waterproof membranes, and then manually align the anti-scour plate with the joint position, and rely on the operator to manually press to achieve bonding. This traditional process has obvious technical defects: first, it is difficult to achieve precise positioning by manual alignment, and joint misalignment is prone to occur; second, the manual pressing force is uneven, and local pressure fluctuations are prone to occur, resulting in bubbles and false adhesion on the bonding surface; third, the construction efficiency is low, and the quality of continuous operation is unstable due to the physical limitations of workers.

[0004] In order to solve the above problems, the utility model proposes an automatic pressing device for waterproof coiled material joint anti-scouring plates. Utility Model Content

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0023] See also Figure 1-3 The utility model provides a technical solution: an automatic pressing device for waterproof roll material joint anti-scouring plates, comprising a fixed plate 1 and an anti-scouring plate 2, three suction pipes 3 are fixedly installed on the fixed plate 1, the three suction pipes 3 are evenly distributed along the fixed plate 1, the bottom ends of the suction pipes 3 are fixedly connected with suction cups 4, and the anti-scouring plates 2 are adsorbed on the bottom ends of the suction cups 4.

[0024] Fixed pipes 5 are fixedly installed on both sides of the lower end surface of the fixed plate 1 corresponding to the suction pipe 3 , and a plurality of one-way air valves 6 are evenly fixedly connected to the top of the outer wall of the fixed pipe 5 around the axis of the fixed pipe 5 .

[0025] By adopting the above technical solution, multiple one-way air valves 6 are evenly arranged on the top of the outer wall of the fixed tube 5, ensuring the reliability and rapid response of air pressure regulation, and providing stable guarantee for the formation and release of negative pressure of the suction cup 4.

[0026] The bottom end of the fixed tube 5 is sealed and slidably mounted with a support rod 7 ; specifically, the interior of the fixed tube 5 is sealed and slidably mounted with a piston 14 , which is fixedly connected to the top end of the support rod 7 .

[0027] By adopting the above technical solution, the precise movement of the piston 14 in the fixed tube 5 realizes the smooth lifting and lowering of the support rod 7, while ensuring the air tightness, and providing stable mechanical support for the adsorption function of the suction cup 4.

[0028] The fixed tube 5 is connected to the corresponding suction tube 3 through a connecting tube 15. Specifically, the top of each suction tube 3 is fixedly connected with a connecting tube 15, and both ends of the connecting tube 15 are respectively connected to the fixed tubes 5 at the corresponding two sides.

[0029] In the embodiment of the utility model: a plurality of electric push rods 8 are evenly fixedly mounted on the fixed plate 1, and a pressing plate 9 is fixedly arranged on the output end of the electric push rod 8, and the pressing plate 9 is in abutment with the anti-scouring plate 2. Specifically, a U-shaped frame 10 is fixedly mounted on the output end of the electric push rod 8, and two pressing plates 9 are fixedly mounted on the bottom ends of both sides of the U-shaped frame 10 respectively.

[0030] It should be noted that the output end of the servo electric push rod 8 (rated thrust 500N) pushes the U-shaped frame 10 and the pressure plate 9 downward at a gradient pressure of 15N / s through the force control mode. The bottom of the pressure plate 9 compacts the anti-scour plate 2 and the joint with a uniform pressure of 0.25MPa, and the pressure is automatically unloaded after being maintained for 3s.

[0031] By adopting the above technical solution, the U-shaped frame 10 connects the two pressing plates 9 to the output end of the electric push rod 8, thereby achieving bidirectional uniform pressure on the anti-scouring plate 2 and effectively improving the pressing quality.

[0032] In the embodiment of the utility model: a fixing ring 11 is fixedly installed on the outer wall of the fixing tube 5, a foot pad 12 is fixedly installed on the bottom end of the support rod 7, and a spring 13 is sleeved on the outer side of the fixing tube 5, one end of the spring 13 is fixedly connected to the fixing ring 11, and the other end of the spring 13 is fixedly connected to the foot pad 12. The spring 13 connects the fixing ring 11 and the foot pad 12, provides elastic restoring force for the support rod 7, and plays a role in buffering and shock absorption.

[0033] In the embodiment of the utility model: a plurality of limit spring rods 16 are fixedly installed on both sides of the fixed plate 1 corresponding to the anti-scour plate 2, and the telescopic ends of the limit spring rods 16 are slidably fitted with the side walls of the anti-scour plate 2. The sliding fit of the plurality of limit spring rods 16 with the side walls of the anti-scour plate 2 ensures accurate positioning of the anti-scour plate 2 during the movement and pressing process to prevent position deviation.

[0034] In the embodiment of the utility model: a handle 17 is fixedly mounted on the upper end surface of the fixing plate 1. A comfortable gripping position is provided for the operator, which is convenient for the carrying and positioning operation of the equipment and improves the construction convenience.

[0035] It should be noted that the various devices in this application are common devices in the market and can be selected according to specific needs when used. Here we only use them and have not made any improvements to their structure and function, so we will not go into details here.

[0036] Working principle:

[0037] First, place the anti-scour plate 2 horizontally on the platform, then move the suction cup 4 at the bottom of the equipment to just above the anti-scour plate 2. The operator holds the handle 17 with both hands, and clamps the telescopic ends of the limit spring rods 16 on both sides of the anti-scour plate 2 to complete the mechanical pre-positioning. At this time, slowly push the handle 17 downward to drive the fixed plate 1 to move down smoothly, so that the support rod 7 and the piston 14 slide upward in the inner cavity of the fixed tube 5, and compress the spring 13 at the same time. At this time, the suction cup 4 is not in contact with the anti-scour plate 2. When the silicone sealing ring of the suction cup 4 contacts the surface of the anti-scour plate 2 and produces a preliminary seal, the support rod 7 reaches the end of the stroke, the operator stops pressing down, and the spring 13 begins to release the stored energy, pushing the piston 14 and the support rod 7 to return downward, forming a negative pressure in the suction cup 4 to ensure that the anti-scour plate 2 is firmly adsorbed.

[0038] Then, hold the handle 17 to move the entire device to the joint of the waterproof membrane, brush the polyurethane base treatment agent in advance, place the foot pads 12 on both sides and the limit spring rod 16 on both sides of the joint, so that the anti-scouring plate 2 is located in the middle position of the joint, press the fixed plate 1 downward, so that the support rod 7 and the piston 14 slide upward inside the fixed tube 5, and at the same time drive the spring 13 to contract, and pass through the one-way air valve 6. The external air enters the fixed tube 5 after being filtered by the one-way air valve 6, and is introduced into the suction tube 3 through the connecting pipe 15 to balance the internal and external pressures of the suction cup 4, so that the anti-scouring plate 2 is separated from the suction cup 4. Under the guidance of the limit spring rod 16, the anti-scouring plate 2 falls vertically and falls on the joint, and the electric push rod 8 is started. The output end of the electric push rod 8 drives the U-shaped frame 10 and the pressing plate 9 to move downward, so that the pressing plate 9 moves downward to press the anti-scouring plate 2, so that the anti-scouring plate 2 is evenly stressed and pressed against the joint, thereby improving the connection efficiency.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
