Description

Technical Field

[0001] The present invention relates to an automatic plate cutting device for a plastic drainage plate inserting boat. Background Art

[0002] As a plastic plate drainage method for soft soil foundation treatment, it is a method that uses an inserting machine to insert strip-shaped plastic drainage plates into soft soil, and then applies surcharge preloading (or vacuum preloading). The pore water in the soft soil will escape through the channels of the plastic drainage plates, so that the soft foundation can be consolidated and the strength can be increased. The traditional plastic drainage plate inserting method is as follows: manually insert the plastic drainage plate into the inserting sleeve; manually hold the root of the drainage plate and follow the inserting sleeve down until the head of the drainage plate touches the soft foundation mud surface and then let go. The inserting sleeve "presses" the drainage plate into the bottom mud to the specified depth; then the inserting sleeve is withdrawn from the bottom mud surface, and the operator uses a sickle or a hydraulic scissors to reach a certain height above the bottom mud surface to cut the drainage plate, completing one inserting operation. When the operator performs the plate cutting operation, he needs to stand on the edge of the operation platform of the inserting boat, and there is a safety risk of falling into the water during the operation. The underwater inserting operation personnel cannot directly observe the underwater situation and cannot accurately control the cutting position of the drainage plate. To ensure the construction quality, generally a large margin is maintained for the length of the drainage plate exposed above the bottom mud surface, resulting in a large loss of drainage plates.

[0030] The scissors 4 includes a sleeve plate 40, two scissor arms 41, a return spring 42 and two electromagnets 43; wherein,

[0031] The sleeve plate 40 is in the shape of a circular ring with an inner diameter larger than the outer diameter of the insertion plate sleeve 17. The sleeve plate 40 is arranged around the insertion plate sleeve 17. The sleeve plate 40 includes an upper layer circular steel plate 40A, a lower layer circular steel plate 40B and three isolation struts 400 connecting the upper layer circular steel plate 40A and the lower layer circular steel plate 40B; the inner diameters of the upper layer circular steel plate 40A and the lower layer circular steel plate 40B are the same, and the outer diameters of the upper layer circular steel plate 40A and the lower layer circular steel plate 40B are also the same; the isolation strut 400 can be composed of bolts and three nuts; two pairs of tie rope rings 401 corresponding to the two pairs of scissors lifting ropes 32 are installed on the top surface of the upper layer circular steel plate 40A, so that the sleeve plate 40 is connected to the lower ends of the two pairs of scissors lifting ropes 32.

[0032] The scissor arm 41 includes a blade section 411 and a handle section 412. The inner side of the blade section 411 is provided with a blade. The length of the blade section 411 is greater than the inner diameter of the sleeve ring 40. The two scissor arms 41 are cross-arranged between the upper layer circular steel plate 40A and the lower layer circular steel plate 40B, and the blade sections 411 of the two scissor arms 41 are both located inside the sleeve plate 40 and are located on both sides of the plastic drain board 5 in one-to-one correspondence, while the handle sections 412 of the two scissor arms 41 are located outside the sleeve plate 40.

[0034] Two electromagnets 43 are respectively mounted on the inner sides of the handle segments 412 of the two scissors arms 41; a cable 44 is connected to the electromagnet 43, and the cable 44 sequentially passes upward through the wire loops 24 on the two limit frames 2 and then enters the cab 14, and is connected to the plate cutting controller in the cab 14;

[0035] For the automatic plate cutting device of the plastic drainage plate inserting boat of the present invention, the cab 14 serves as the operation room for the plate cutting operation and can be shared with the cab of the inserting boat. The cab 14 introduces a plate cutting controller to realize remote operation of the plate cutting operation. The two pairs of guide rope loops 23 on the two limit frames 2 can radially position the scissors 4, so that the socket plate 40 of the scissors 4 is in a horizontal state. The shearing winch 31 and the two pairs of scissors lifting ropes 32 can control the height position of the scissors 4, so as to control the exposed length of the drainage plate 5.

[0036] For the automatic plate cutting device of the plastic drainage plate inserting boat of the present invention, when inserting the plastic drainage plate 5, the inserting boat sails into the construction water area. First, the drainage plate upper socket on the drainage plate inserting and mounting plate of the plastic drainage plate 5 is inserted into the drainage plate through hole in the inserting sleeve 17, so that the plate head of the plastic drainage plate 5 penetrates out of the shoe mounted at the bottom of the inserting sleeve 17, and the plate head of the plastic drainage plate 5 is wound on the shoe. Then, the inserting winch is started to lower the vibrating hammer 15, and the inserting sleeve 17 is inserted into the set depth below the water bottom surface through the exciting force of the vibrating hammer 15. When pulling out the inserting sleeve 17, the vibrating hammer 15 and the inserting sleeve 17 are lifted by the inserting winch, and the plate head of the plastic drainage plate 5 still stays in place, thus completing the driving process of the plastic drainage plate 5. During the downward movement of the inserting sleeve 17, the operator in the cab 14 remotely operates the switch of the shearing winch to drive the shearing winch 31 and the two pairs of scissors lifting ropes 32 to lower the scissors 4 at the same height as the bottom of the row frame 13. The operator determines whether the scissors 4 are lowered to the bottom mud surface by observing the slack degree of the two pairs of scissors lifting ropes 32. After the inserting sleeve 17 is pulled out of the bottom mud surface, the operator remotely operates the switch of the shearing winch to control the shearing winch 31 and the two pairs of scissors lifting ropes 32 to lift the scissors 4 so that the scissors 4 are located at the set exposed length position of the plastic drainage plate 5. Then, the operator makes the electromagnet 43A energized through the remote operation switch of the scissors, so that the two electromagnets 43 attract each other against the elastic force of the return spring 42, driving the blade segments 411 of the two scissors arms 41 to close and cut the plastic drainage plate 5. Then, the operator makes the electromagnet 43A de-energized through the remote operation switch of the scissors, and the two electromagnets 43 no longer attract each other, and the blade segments 411 of the two scissors arms 41 are separated by the return spring 42. After the plate cutting operation is completed, the operator remotely operates the switch of the shearing winch to drive the shearing winch 31 to retract the two pairs of scissors lifting ropes 32, so that the scissors 41 rise to the horizontal position at the same height as the bottom of the row frame 13, waiting for the next plate cutting operation. The entire plate cutting operation does not require the participation of operating personnel and only needs to be controlled by the operator in the cab, effectively reducing the safety risk of manual operation.

[0037] The above embodiments are only for illustrating the present invention, rather than limiting the present invention. Those skilled in the relevant technical fields can also make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and should be defined by each claim.
