Abstract
Description
Technical Field
[0001] The utility model relates to the field of gate maintenance equipment, in particular to a flat gate pin shaft disassembly device. Background Art
[0002] Before the metal joint center of various flat gates in power stations is anti-corroded, various pins need to be removed so that the gates can be dismantled for maintenance. Since the gates have been in operation for more than ten years, the pin surfaces and gate bodies are severely corroded, making disassembly difficult.
[0003] At present, there are no professional tools or practical solutions for the removal of rusted pins of flat-type gates and similar working conditions in China. Most of them are carried out by using rust removers or hot work in combination with vibrating hammers, manual impact on the pins, etc. A few use "woodpeckers" to cooperate with the work. Some companies, such as the Sanhe Gate Steel Gate Lifting Ear Pin, rely on changing the chemical material of the pin to reduce the degree of corrosion, and increasing the gap between the shaft and the shaft hole.
[0004] Relying on instruments such as vibrating hammers to hit the pin shaft or using instruments such as "woodpeckers" to assist cannot ensure that the hammer head and the gate are relatively stable, and the rebound is serious, which is easy to damage the gate and the pin shaft. In addition, the size is large and the operation cost is high. Using a hydraulic excavator with a hydraulic vibrating hammer (hydraulic breaker) or manually hitting the shaft to remove the shaft will cause certain damage to the gate, and the removal cost is high and the efficiency is low. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide a flat gate pin shaft disassembly device, which is used to disassemble the rusted pin shaft of the flat gate, prevent the vibration hammer from deviating from the pin shaft, and improve the disassembly efficiency.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a flat gate pin shaft disassembly device, including a machine base, which is connected to a support platform through a positioning mechanism, a mounting seat is provided on the support platform, a hydraulic clamp and a vibrating hammer are provided on the mounting seat, a through hole matching the vibrating hammer is provided on the mounting seat, the vibrating hammer is hinged to the propulsion mechanism, the propulsion mechanism includes a propulsion rod hinged to the vibrating hammer, a strip groove for the propulsion rod to move is provided on the support platform, the lower end of the propulsion rod is hinged to the connecting rod, the other end of the connecting rod is hinged to the machine base, the adjusting cylinder is hingedly installed on the machine base, and the telescopic end of the adjusting cylinder is hinged to the propulsion rod.
[0007] In a preferred solution, the positioning mechanism includes a lifting cylinder, the lower end of the lifting cylinder is connected to the machine base, and the telescopic end is connected to the support platform.
[0008] In a preferred solution, the positioning mechanism also includes an angle adjustment cylinder whose tail end is hingedly mounted on the machine base, a telescopic end of the angle adjustment cylinder is hingedly connected to the support platform, and a telescopic end of the lifting cylinder is hingedly connected to the support platform.
[0009] In a preferred solution, travel wheels are provided at the bottom of the machine base.
[0010] The utility model provides a flat gate pin disassembly device, which has the following beneficial effects:
[0011] 1. The entire device is fixed on the gate by hydraulic clamps, which can ensure that the pin is always in contact with the drill rod, ensuring that the gate or device will not move, and avoiding the problem of the drill rod being separated from the pin due to vibration and needing to be repositioned.
[0012] 2. Ensure that the axis of the drill rod is always parallel to the axis of the pin, so that the vibration force and propulsion force of the drill rod of the vibration hammer can all act in the moving direction of the pin, and no lateral force will be generated, resulting in a waste of power.
[0013] 3. Since the vibration hammer moves along the through hole on the mounting seat, it can ensure that the vibration hammer maintains a linear feed, and can prevent the gate and the vibration hammer from moving relative to each other during the vibration hammer's impact on the pin shaft, thereby preventing the vibration hammer from being hit off-center and stuck.
[0014] 4. The device can be adjusted in height and inclination to adapt to different working environments and improve adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] Embodiment 1:
[0021] like Figures 1 to 3As shown, a flat gate pin shaft disassembly device includes a machine base 1, which is connected to a support platform 2 through a positioning mechanism. The positioning mechanism can be a support frame or a support rod or other structures. A mounting seat 3 is provided on the support platform 2, and a hydraulic clamp 4 and a vibrating hammer 5 are provided on the mounting seat 3. A through hole matching the vibrating hammer 5 is provided on the mounting seat 3, and the vibrating hammer 5 can move forward and backward along the through hole. In this embodiment, the vibrating hammer 5 uses a 180KW vibrating hammer.
[0022] The hydraulic clamp 4 may be provided with a through hole for the drill rod 501 of the vibration hammer 5 to pass through, that is, the drill rod 501 of the vibration hammer 5 is located between the two clamps of the hydraulic clamp 4, thereby improving the compactness of the entire device.
[0023] Alternatively, the vibration hammer 5 and the hydraulic clamp 4 can also be arranged horizontally and in parallel, that is, the relative horizontal left and right positions and the up and down positions of the vibration hammer 5 and the hydraulic clamp 4 remain unchanged, and the vibration hammer 5 can only be pushed forward and backward along the through hole of the mounting seat 3.
[0024] The outer shell of the vibration hammer 5 is hinged to the propulsion mechanism, and the propulsion mechanism includes a propulsion rod 7 hinged to the vibration hammer 5. The propulsion rod 7 is tilted, and a strip groove 201 for the propulsion rod 7 to move is provided on the support platform 2. The propulsion rod 7 can move or swing in the strip groove 201. The lower end of the propulsion rod 7 is hinged to the connecting rod 8, and the other end of the connecting rod 8 is hinged to the machine base 1. The adjusting cylinder 9 is hingedly installed on the machine base 1, and the telescopic end of the adjusting cylinder 9 is hinged to the propulsion rod 7.
[0025] During the extension and retraction process of the adjustment oil cylinder 9 , the propulsion rod 7 can be pulled to swing and move up and down, thereby forming a driving force for the vibration hammer 5 , thereby achieving the front and rear position adjustment of the vibration hammer 5 .
[0026] In actual use, the bottom of the base 1 is provided with running wheels to facilitate the movement of the entire device.
[0027] Alternatively, the base 1 may also be placed on a forklift or a mobile trolley for loading, so as to achieve movement of the device or height adjustment of the device.
[0028] Embodiment 2:
[0029] Different from Example 1, Figure 1 and 3 As shown, the positioning mechanism includes a lifting cylinder 10 , the lower end of the lifting cylinder 10 is connected to the machine base 1 , and the telescopic end is connected to the support platform 2 .
[0030] By extending and retracting the lifting cylinder 10, the height of the support platform 2 can be adjusted, thereby cooperating with the adjusting cylinder 9 to adjust the working height, and adjusting the height of the pin shaft of different types of gates to improve adaptability.
[0031] Furthermore, the positioning mechanism also includes an angle adjustment cylinder 6 , the rear end of which is hingedly mounted on the machine base 1 , the telescopic end of the angle adjustment cylinder 6 is hingedly connected to the support platform 2 , and the telescopic end of the lifting cylinder 10 is hingedly connected to the support platform 2 .
[0032] Since the telescopic end of the lifting cylinder 10 is hinged to the support platform 2, when the angle adjustment cylinder 6 is extended or retracted, the support platform 2 can be rotated along the hinge position with the lifting cylinder 10, so as to adjust the angle of the support platform 2. When the gate is placed unevenly so that the pin shaft has a certain inclination angle, the advancement angle of the vibration hammer 5 is made consistent with the pin shaft to prevent the deviation and jamming caused by the angle change during the advancement process of the shaft removal.
[0033] The working principle of this device is as follows:
[0034] First, move the device to the vicinity of the gate where the pin shaft is to be disassembled. According to the height and angle of the pin shaft, start the lifting cylinder 10 and the angle adjustment cylinder 6, adjust the angle of the drill rod of the vibration hammer 5 to make it exactly set on the pin shaft to be disassembled, then start the adjustment cylinder 9 to push the vibration hammer 5 so that the pin shaft is within the operating range of the drill rod 501 of the vibration hammer 5, start the hydraulic clamp 4 to clamp it on the gate, and fix the entire device to the gate to prevent the gate or the device from moving during the disassembly process and causing deviation; then start the vibration hammer 5 to vibrate and disassemble the pin shaft.
[0035] The device replaces the manual hammering method or the vibration hammer method for dismantling the rusted pin shaft, which can ensure that the hammer will not deviate during the hammering process to cause damage to the gate or the phenomenon of deviation and jamming, thereby improving the dismantling efficiency.
