Description

Technical Field:

[0001] The present invention relates to the technical field of water conservancy maintenance equipment, and more specifically to a multifunctional vehicle for disassembling and assembling gate tie rods. Background Art:

[0002] A reservoir is generally explained as "a water conservancy project building for flood interception, water storage, and water flow regulation, which can be used for irrigation, power generation, flood control, and fish farming." It refers to an artificial lake formed by building a dam across a narrow valley or river. After the reservoir is built, it can play roles such as flood control, water storage for irrigation, water supply, power generation, and fish farming.

[0003] Existing reservoirs generally have multiple sluice gates. Some of the sluice gates are connected to a conveying channel for delivering fresh water to other places. An opening and closing machine room is provided at the sluice gate. A gate is provided below the opening and closing machine room. The gate blocks the sluice gate. By opening the gate, the water in the reservoir can flow out into a specified flow channel. After a certain period of time, the gate needs to be overhauled. Since the ground of the opening and closing machine room is higher than the water level, and the gate is generally located at the bottom of the reservoir, the height difference between the two is relatively large. At this time, multiple sections of tie rods are installed on the top of the gate, and the top of the top tie rod is fixed to a connecting seat on a wire rope of a hoist installed on the floor of the opening and closing machine room. Similarly, a maintenance gate mechanism with the same structure is installed on the opening and closing machine room. During maintenance, first lower the maintenance gate to block the sluice gate, and then lift the gate to be repaired and maintained. Since multiple sections of tie rods are connected, it is impossible to lift the gate out of the gate lifting through hole on the ground of the opening and closing machine room at one time. When the wire rope of the hoist reaches the top, only some of the tie rods can be extended out of the gate lifting through hole. At this time, only the corresponding tie rods can be disassembled one by one to gradually lift the gate until it can be extended out of the gate lifting through hole for overhaul. Since a connecting plate part is provided at the connection between two adjacent tie rods above and below, and a pin shaft is inserted into the through holes of the corresponding four connecting plate parts to achieve connection, when disassembling, the pin shaft connecting the two tie rods needs to be disassembled;

[0004] The disassembly process of the existing tie rod is as follows. Through the pulling of the steel wire rope of the hoist, the top of the tie rod below the topmost tie rod is positioned above the gate lifting through-hole. Assume the tie rod to be disassembled is the first tie rod, and the tie rod below the first tie rod is the second tie rod. Two locking beams need to be placed on the ground on both sides of the gate lifting through-hole. Then, by operating the hoist, the first tie rod is lowered a certain distance so that the support blocks on both sides of the upper part of the second tie rod press against the top surfaces of the two locking beams. Then, the locking plate at the pin shaft is disassembled, and the pin shaft is pulled out. Since the tie rod generally weighs four or five hundred kilograms and the pin shaft also weighs two or three hundred catties, the existing disassembly method is generally to manually push out the pin shaft step by step with a hammer, etc. During the pushing process, it is necessary to manually wind a rope around the protruding part of the pin shaft and then manually pull and support it to ensure that the pin shaft does not fall when it comes out. It requires multiple people to support and pull, and the manual labor intensity is very high. Then, it is carried. After the pin shaft is disassembled, the first tie rod and the second tie rod are separated. At this time, multiple people need to support and pull the bottom of the first tie rod outwards. Then, through the continuous lowering of the movable pulley block of the steel wire rope of the hoist, the first tie rod is lowered, and at the same time, the first tie rod moves obliquely outwards until the head of the first tie rod is close to the top of the second tie rod. At this time, the first tie rod is horizontal. Place the fork of the trolley (a manual hydraulic stacker can be used) below the middle part of the first tie rod, lift the fork and press it against the bottom surface of the middle part of the first tie rod to achieve support. Then, remove the pin shaft at the connection between the connecting plate of the movable pulley block and the top of the first tie rod. At this time, the first tie rod needs to be completely separated from the equipment. At this time, by multiple people pulling the trolley and supporting the first tie rod, it can be moved out to complete the disassembly. Then, lower the movable pulley block, connect it to the second tie rod through a pin shaft, and then operate the hoist to lift the second tie rod. In the same way as before, disassemble the second tie rod. In this way, the tie rods are gradually disassembled in sequence until the gate extends above the gate lifting through-hole. Then, it can be repaired and maintained, such as replacing the sealing strip of the gate, etc.

[0005] This process is all manually operated, with poor effect and low efficiency. It often takes nearly a month to repair one gate, and nearly twenty people are needed for operation, which is time-consuming and laborious. Summary of the Invention:

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a multi-functional vehicle for disassembling and assembling the gate tie rod. It can assist in disassembling the pin shaft, and at the same time, can clamp the bottom of the tie rod to assist the tie rod to move obliquely outwards and descend for support, making the disassembly convenient. It only requires three to five people to operate, greatly reducing the manual labor intensity, saving time and effort, and having a good effect.

[0047] When disassembling the tie rod of the gate in this embodiment, generally, one multifunctional vehicle and one manual hydraulic stacker of this embodiment are required, and then, one more manual hydraulic platform truck is needed. Both the manual hydraulic stacker and the manual hydraulic platform truck are products that can be directly purchased on the market.

[0048] The process of disassembling the tie rod is as follows:

[0049] 1. First, start the hoist and lift the tie rod of the gate that needs to be repaired and maintained. When the top tie rod (the first tie rod) and the tie rod (the second tie rod) below it extend out of the valve lifting through hole on the ground of the hoist room, then, place the left and right locking beams on the ground at the left and right parts of the valve lifting through hole. Then, through the operation of the hoist, slightly lower the first tie rod so that the support seat on the outer side wall of the second tie rod is pressed against the top surface of the corresponding locking beam. At this time, observe and confirm whether the locking beam is completely supported. After confirmation, lower the first tie rod again to make the pin shaft at the connection of the first tie rod and the second tie rod relatively loose, and clean the dirt on the pin shaft.

[0050] 2. Unscrew the lock piece bolt on the pin shaft and fix a power-assisted rod (a horizontal straight rod) at one end of the pin shaft to facilitate the movement of the pin shaft in the extraction direction.

[0051] III. Push this embodiment. Place channel steel rails at the left and right parts of the valve lifting through-hole. The bottom surface of the channel steel rail presses against the ground of the hoisting machine room. Then, push the trolley wheels 17 of this embodiment along the channel steel rails. By operating the foot pedal or manual lever at the rear of the hydraulic cylinder 21, the height position of the push rod of the hydraulic cylinder 21 can be adjusted, thereby adjusting the height position of the lifting frame 30. Move the claw 47 of the gripper mechanism 40 close to the pin shaft (two claws 47 are shown in the attached drawing, and actually there are at least six claws 47). By rotating the rotating wheel 45, all the claws 47 are spread out, and then move to the pin shaft so that the radially extending edge formed on the outer side wall of the corresponding end of the pin shaft is located in the clamping grooves 473 of all the claws 47. Then, rotate the rotating wheel 45 again so that all the claws 47 come closer together, clamping the radially extending edge at all the claws 47 to achieve locking. Then, push the resistance through the assisting rod to move the long rod body 53 outward at the end of the pin shaft with the radially extending edge. When the pin shaft is moved out by 2 / 3, rotate the long rod body 53 and operate the hand chain hoist 56. Tie the rope around the lifting center of the pin shaft, hook the upper end of the rope to the hook part of the hand chain hoist 56, hoist the pin shaft and adjust its height to keep it horizontal. Then, push the pin shaft out forcefully. The long rod body 53 rotates, and after the pin shaft is moved out, place it on the corresponding pusher trolley and then it can be pushed out.

[0052] IV. Then, push this embodiment to move it to an appropriate position. By adjusting the height position of the push rod of the hydraulic cylinder 21, adjust the height position of the positioning circular block 37 to the required height. Manually rotate the two adjusting rotating wheels 39 to make the two positioning circular blocks 37 close to the two connecting plate parts at the bottom of the first pull rod, and finally make the circular convex positioning part 371 insert into the pin connection through-hole at the corresponding connecting plate part. The connecting plate part closely adheres to the end face of the corresponding positioning circular block 37. Then, the hoisting machine operates to slowly lower the first pull rod. While lowering, move this embodiment backward. In this embodiment, generally move backward about 2 meters. At this time, the first pull rod moves obliquely backward.

[0053] V. Use a manual hydraulic platform truck as a transfer truck and move it to the bottom end of the first pull rod. Press the bottom end of the first pull rod against the top surface of the lifting plate of the transfer truck. Then, rotate the two adjusting rotating wheels 39 to separate the two positioning circular blocks 37 from the first pull rod. At the same time, slowly lower the height of the first pull rod. At this time, the transfer truck moves backward to adjust the inclination of the first pull rod so that the head of the first pull rod rests on the head of the second pull rod (it is necessary to ensure that the wire rope of the movable pulley always remains in a natural vertical state).

[0054] VI. Move the manual hydraulic stacker (schematic diagram in the attached figure) to the middle side of the first pull rod, move its fork under the middle bottom surface of the first pull rod, and lift it by manually adjusting the lifting rod of the hydraulic cylinder of the manual hydraulic stacker, so that the main cross bar of the hydraulic cylinder is lifted, the fork is lifted, and it is pressed against the middle bottom surface of the first pull rod to achieve middle support (the manual hydraulic stacker here can also be a multi-functional vehicle identical to that in this embodiment, and the fork 510 on it can be used for support). In the same way, remove the pin shaft at the connection between the connecting plate of the movable pulley group and the top of the first pull rod. Then, confirm whether the pin shaft is separated from the first pull rod.

[0055] VII. After separation, pull the transfer vehicle backward again, so that the first pull rod gradually becomes horizontal and finally completely presses against the fork of the manual hydraulic stacker. Then, by moving this manual hydraulic stacker, the first pull rod can be removed to achieve disassembly. Its disassembly effect is good, the efficiency is high, and the operation difficulty is greatly reduced.

[0056] After the first pull rod is disassembled, the movable pulley group can be lowered, connected to the top of the second pull rod through a pin shaft, and then the second pull rod can be lifted for disassembly. The subsequent operations can be the same as the above method to disassemble all the pull rods.
