Description

Technical Field:

[0001] This application relates to the technical field of laying devices, in particular to a membrane bag laying device. Background Art:

[0002] Relevant research shows that more than 90% of dam breaches are caused by piping. For thousands of years, the method of plugging piping has been to throw sand, gravel, soil bags or wicker bundles. Since the leakage channels of piping in the dam body are curved and irregular, it is impossible to determine the leakage points on the upstream face of the dam, and it can only be thrown blindly, resulting in very low plugging efficiency, and most of the thrown materials do not cover the leakage holes.

[0003] The invention patent with the application number CN201310162203.6 - a cloth bag laying device. This device is provided with a flatbed truck, and two winches are relatively arranged on the flatbed truck. The two winches are respectively connected to both ends of a rotating shaft through steel wires. A drum is arranged on the rotating shaft, and the drum can rotate on the rotating shaft. A membrane bag is wound around the drum. One end of the membrane bag is provided with a fixing rod, and the other end of the membrane bag is wound around the drum. A sand inlet is arranged on the membrane bag near the fixing rod end. Two or more sand inlets can be set. According to the number of sand inlets, high - strength lines are used to set membrane bag dividing lines on the membrane bag to divide the membrane bag. The winches are synchronous winches.

[0004] The two winches in this device control the drum through steel wires, and use the self - weight of the drum to lay the membrane bag. However, not all dams have a flat structure. When laying on an uneven dam, if one side of the drum is blocked and the other side is unobstructed, it is easy to cause the winding direction of the membrane bag to deviate from the original predetermined route, affecting the laying progress and quality; and the horizontal section beyond the toe of the slope cannot be laid due to the loss of power. Utility Model Content:

[0025] By arranging the support device to support the telescopic arm, it is prevented that the front end of the telescopic arm touches the ground due to the change of the center of gravity during the extension process of the telescopic arm, ensuring the stability of the device.

[0029] To make the purpose, technical solutions and advantages of the implementation of the present utility model clearer, the present utility model will now be further described in detail with reference to the accompanying drawings and the following embodiments, so that the public can better master the implementation method of the present utility model. The specific implementation scheme of the present utility model is as follows:

[0030] The membrane bag laying device includes a traveling mechanism 1. The traveling mechanism 1 is provided with a telescopic arm 2 or a folding arm. The front part of the telescopic arm 2 or the folding arm is provided with a laying frame 3. The laying frame 3 is provided with a clamping mechanism. The clamping mechanism is connected to the roller 17 through a rotating shaft; through the cooperation of the telescopic arm 2 or the folding arm and the laying frame, the membrane bag is laid along a predetermined path, which can meet the needs of laying membrane bags on complex dams, improve work efficiency, ensure construction quality, and can extend to the horizontal section at the toe of the slope for laying, improving practicability.

[0031] Specifically, the traveling mechanism 1 is a crawler chassis, which has better passability and is suitable for complex terrains and harsh working conditions; the crawler chassis is provided with a rotary drive for connecting the telescopic arm 2 or the folding arm. Through the rotary drive, the telescopic arm 2 or the folding arm can rotate 360 degrees, improving operation flexibility.

[0032] It should be noted that a support base 6 is provided on the upper end surface of the rotary drive in a fixed structure manner. The support base 6 is connected to the telescopic arm 2 in a hinged structure manner. A power device 7 is provided between the support base 6 and the telescopic arm 2. The power device 7 is used to drive the telescopic arm 2 to rotate around the hinge point with the support base 6. The telescopic arm 2 can adjust the angle according to the slope of the dam, improving adaptability. Specifically, the power device 7 is a hydraulic cylinder or a telescopic cylinder.

[0033] It should be elaborated that an installation frame 8 is provided at the front end of the telescopic arm 2. The installation frame 8 can be of an L-shaped structure. A connecting arm 9 is provided at the horizontal section of the installation frame 8 in a hinged structure manner. The connecting arm 9 is connected to the laying frame 3 in a fixed structure manner. An electric cylinder is provided inside the vertical section of the installation frame 8. The output end of the electric cylinder is connected to a chain or a wire rope. The other end of the chain or the wire rope is connected to the laying frame 3 or the connecting arm 9. The electric cylinder drives the connecting arm 9 to rotate around the hinge point through the chain or the wire rope, thereby lifting the laying frame 3 to prevent the clamping mechanism from hooking the film bag when the telescopic arm 2 retracts, ensuring that the film bag is not damaged.

[0034] Specifically, the clamping mechanism includes semi-circular hooks 16 fixedly connected to both ends of the laying frame 3. A semi-circular lock 17 is provided on one side of the semi-circular hook 16 in a hinged structure manner. The other end of the semi-circular lock 17 is detachably connected to the semi-circular hook 16 through a pin shaft. The film bag is wound around the roller 17. Rotating shafts are provided at both ends of the roller 17, and the rotating shafts are connected to the semi-circular hook 16. By using the opening and closing actions of the semi-circular hook 16 and the semi-circular lock 17, the roller 17 is installed or removed.

[0035] It should be elaborated that a support device 10 for preventing the telescopic arm 2 from tipping over is provided at the lower part of the installation frame 8. The support device 10 is a cylinder or a triangular crawler wheel. The cylinder is connected to the installation frame 8 through a U-shaped frame. The cylinder is of a hollow structure to reduce its own weight, support the telescopic arm 2, prevent the front end of the telescopic arm 2 from touching the ground due to the change of the center of gravity during the extension process of the telescopic arm 2, and ensure the stability of the device; it can also press the film bag on the surface of the dam to ensure that the film bag does not float in the water.

[0036] On the basis of the above embodiments, in another embodiment, a connecting rod 11 is provided on the laying frame 3. A leak detection frame 12 is provided at the other end of the connecting rod 11. Probes 13 of a dam piping leakage detector are evenly spaced on the leak detection frame 12. The probe 13 is connected to a receiver. When the transmitter emits a signal, an induced signal will be generated on the dam slope. The probe 13 monitors the magnitude of the induced signal in real time and feeds it back to the receiver. The abnormal point of the induced signal is the piping leakage point. If a piping point is found, concrete can be poured into the film bag immediately to plug the piping point, greatly shortening the emergency rescue time.

[0037] For the convenience of transporting the device, the connecting rod 11 is connected to the laying frame 3 in a hinged manner. When not in use, the leak detection frame 12 can be rotated above the telescopic arm 2; the leak detection frame 12 is also provided with rollers for supporting the leak detection frame 12; to ensure the detection accuracy of the probe 13, both the leak detection frame 12 and the connecting rod 11 are made of hard insulating materials.

[0038] It should be noted that both the laying frame 3 and the leak detection frame 12 include fixed rods 14. Telescopic rods 15 are sleeved on both sides of the fixed rod 14 in a sliding telescopic structure manner, which is convenient for the transfer and transportation of the laying device. It should be noted that the telescopic rod 15 is positioned by a spring pin.

[0039] The membrane bag of this patent refers to a geomembrane and a concrete form bag.

[0040] The working principle and process of this utility model are as follows:

[0041] First, the device is transported to the dam by the crawler chassis 1. Then, the drum 17 wrapped with the membrane bag is placed at the semi-circular hook 16 through the rotating shaft. The semi-circular lock 17 is buckled and connected to the semi-circular hook 16 through the pin shaft to prevent the rotating shaft from falling off within the clamping mechanism.

[0042] According to the slope of the dam, adjust the angle of the telescopic arm 2, and place one end of the membrane bag under the lower part of the cylinder 10 until the cylinder 10 presses the membrane bag against the dam surface. Start the telescopic arm 2 to extend. Since the membrane bag is pressed by the cylinder 10, it is continuously pulled out on the drum 17 and adheres to the dam surface.

[0043] After laying the membrane bag, the telescopic arm 2 retracts. The receiver detects the signal of the piping point and pours concrete into the membrane bag to seal the piping leakage point.

[0044] After laying the membrane bag, if no piping position is found, the telescopic arm 2 retracts. Start the electric cylinder, and use the chain to pull up the laying frame 3 through the connecting arm 9 to avoid the clamping mechanism from hooking the membrane bag lifted by the vegetation, which is convenient for the telescopic arm 2 to quickly retract.
