Description

Technical Field

[0001] This utility model relates to the field of hydraulic gate hoisting technology, and in particular to a piston rod support and leveling device for a hydraulic gate hoisting machine. Background Technology

[0002] Hydraulic gate hoists are commonly used in water conservancy projects such as pumping stations and ship locks. The piston rods of these hoists are often coated, and disassembly and repair are necessary when the coating peels off, the piston rod deforms or is damaged, or the piston seals need replacement. Traditionally, the entire hoist is disassembled and returned to the factory for repair, with the piston rod safely disassembled using specialized tools. However, the entire device weighs over ten tons, making installation and disassembly extremely complex and difficult. Disassembling only the piston rod would significantly reduce workload and maintenance costs. However, the piston rods of hydraulic gate hoists are typically 3-8 meters long and weigh approximately 2 tons. In the field environment, the piston rods lack effective support, making them highly susceptible to damage during disassembly or installation. Therefore, horizontal disassembly and assembly of the piston rods is not feasible. Furthermore, transporting the piston rods is also problematic. Forklifts within the factory area are insufficient for transporting such long equipment, while overhead cranes have limited mobility, making it impossible to transport the piston rods under these challenging conditions. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a piston rod support and leveling device for hydraulic gate hoists. It has a reasonable structural design and is easy to operate. It can complete the transportation and horizontal support of the piston rod in confined working conditions, thereby avoiding damage to the piston rod caused by uneven force on the piston rod. It also enables on-site installation and disassembly of the piston rod, effectively reducing workload and maintenance costs, and solving the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A piston rod support leveling device for a hydraulic gate hoist includes symmetrically arranged support members on the left and right sides, connected by a connecting beam.

The upper end of each guide rod movably passes through the positioning sleeve on the corresponding side and is connected to the positioning block. An abutment block is provided on the inner side wall of the positioning block, which movably abuts against the side wall of the movable column.

[0007] Optionally, the locking seat includes a base fixed to the end of the cylinder piston rod, with inclined plates symmetrically arranged on the front and rear sides of the base surface.

[0022] like Figure 1-6 As shown in this embodiment, a piston rod support leveling device for a hydraulic gate opener includes symmetrically arranged support members on the left and right sides. The two support members are connected by a connecting beam 1. A level 2 is provided on the connecting beam 1. The support member includes a movable column 3 connected to the connecting beam 1. A groove 4 is provided in the center of the surface of the movable column 3. The cylinder seat of a cylinder 5 is fixed to the bottom of the groove 4, and its piston rod extends vertically upward and is connected to the locking seat. A base plate 6 is horizontally arranged below the movable column 3. Several universal wheels 7 are spaced apart along the edge of the bottom of the base plate 6. A cavity 8 is provided in the middle of the base plate 6. A threaded hole 9 is vertically arranged in the center of the bottom of the movable column 3. A vertically arranged lead screw 10 is threaded into the threaded hole 9. Its lower end moves through the surface of the base plate 6 and is connected to a chuck 11 that is movably locked in the cavity 8. A turntable 12 is fixedly sleeved on the lead screw 10 between the base plate 6 and the movable column 3. Several adjusting columns 13 are evenly spaced along the circumference of the side wall of the turntable 12.

[0023] Optionally, a positioning sleeve 14 is vertically installed on the lower part of each side wall of the movable column 3. Several guide rods 15 are installed on the surface of the chassis 6 corresponding to each positioning sleeve 14. The upper end of each guide rod 15 movably passes through the positioning sleeve 14 on the corresponding side and is connected to the positioning block 16. An abutment block 17 is provided on the inner side wall of the positioning block 16, which movably abuts against the side wall of the movable column 3. When the movable column 3 moves up and down, it can move more smoothly along the corresponding guide rods 15 through each positioning sleeve 14. At the same time, each abutment block 17 abuts against the side wall of the movable column 3, providing stable support for the movement of the movable column 3.

[0024] Optionally, the locking seat includes a base 18 fixed to the end of the piston rod of the cylinder 5, and inclined plates 19 are symmetrically arranged on the front and rear sides of the surface of the base 18. The included angle formed by the two inclined plates 19 is used to lock the piston rod of the hydraulic gate opener. Buffer anti-slip pads 20 are provided on the surfaces of the two inclined plates 19.

[0025] Optionally, a limiting plate 21 is provided on the surface of the moving column 3 to abut against the cylinder seat of the cylinder 5. A through hole 22 for the piston rod of the cylinder 5 to pass through is provided in the middle of the limiting plate 21, and a flange 23 is provided at the bottom of the limiting plate 21 to engage between the cylinder seat of the cylinder 5 and the inner wall of the moving column 3. The limiting plate 21 can better fix the position of the cylinder 5, making it more firmly fixed in the groove 4 of the moving column 3, and ensuring the stability of its piston rod movement.

[0026] Optionally, a number of locking lugs 24 are provided at intervals along the length of the front and rear side walls of the connecting beam 1. When it is necessary to transport the piston rod of the hydraulic gate hoist, a rope can be wrapped around the connecting beam and the piston rod and passed through the locking lugs 24 for binding, making it more secure.

[0027] Optionally, all the casters 7 are Mecanum casters. Mecanum casters can more easily achieve displacement in all directions, making it easier for the operator to move the device.

[0028] When this device is used to disassemble the piston rod of a hydraulic gate hoist, it moves on the ground via the casters 7 of the two chassis 6, allowing for flexible movement in complex working conditions unaffected by the environment. When the device moves to the area below the piston rod of the hydraulic gate hoist, firstly, the device's level needs to be adjusted to ensure the connecting beam is parallel to the piston rod. To adjust the level of the left-side moving column 3, a socket tool can be inserted onto one of the adjusting columns 13 of the turntable 12 and pushed to rotate. As the turntable 12 rotates, it drives the lead screw 10 to rotate radially. Its lower end is placed on the chassis 5 via the chuck 11, and its upper end moves the moving column 3 up and down via a threaded connection. At this time, it is necessary to observe the level gauge 2 in the middle of the connecting beam 1 to determine the level of the connecting beam 1. Secondly, when the piston rod of the hydraulic gate hoist extends outward, the piston rods of the two cylinders 5 are activated, causing them to move upward until the inclined plates 19 of the two clamping seats hold the piston rod of the hydraulic gate hoist and provide stable support. The operator then disassembles the piston rod of the hydraulic gate hoist. Finally, the piston rod is tied to the connecting beam 1 with rope. Its reasonable structural design and convenient operation allow for the transportation and horizontal support of the piston rod even in confined spaces, thus avoiding damage to the piston rod caused by uneven stress. This enables on-site installation and disassembly of the piston rod, effectively reducing workload and maintenance costs, and solving problems existing in current technologies.
