Description

Technical Field

[0001] This utility model relates to the field of gate rust removal technology, specifically to a lifting device for a gate rust removal machine. Background Technology

[0002] A lock is a box-shaped hydraulic structure used to ensure the smooth passage of ships and to concentrate water level differences in a waterway. For example, the Three Gorges double-line continuous five-stage lock is the main navigation facility of the Three Gorges Dam. A lock is generally equipped with multiple gates that work together. The gates are coated with a protective coating to ensure their long-term stable use. For example, the Three Gorges double-line five-stage lock has been operating safely and stably for nearly 20 years.

[0003] However, after long-term use, the surface coating of metal structures such as lock gates will gradually approach the design protection period, so rust removal is required. The current method is to send workers and rust removal machines to the front of the lock gate through an aerial work platform, and then the workers operate the rust removal machine to remove rust. The rust removal machines for lock gates are generally sandblasting rust removal machines and laser rust removal machines.

[0004] However, transporting workers and gate rust removal machines via aerial work platforms is not only unstable and poses certain safety hazards, but also inconvenient to operate near the gate and difficult to transport. Utility Model Content

Detailed Implementation

[0037] Example 1:

[0038] like Figure 1 , 2 As shown in Figures 3 and 4, a lifting device for a gate rust removal machine includes a fixed base 1, which is used to install on the top of the gate. The fixed base 1 is provided with a drive mechanism 2, and the drive mechanism 2 is provided with a cable 3, which is preferably a steel cable.

[0039] One end of the cable 3 is provided with a movable seat 4, which is used to install a rust removal machine. The specific type of rust removal machine to be installed depends on the actual usage requirements, such as a sandblasting rust removal machine. The movable seat 4 in this application only needs to reserve the installation position of the rust removal machine.

[0040] The other end of the cable 3 is equipped with a counterweight 6, which is used to balance the forces at both ends of the cable 3;

[0041] Specific usage status as follows: Figure 5 The diagram shown is an embodiment of the lifting device of this application used for rust removal of a gate.

[0042] When in use, the rust removal machine or manual rust removal work platform is installed on the movable base 4. The preferred installation method is bolt connection or welding. During the rust removal process of the gate, the drive mechanism 2 drives the cable 3 to move, thereby moving the movable base 4 to complete the lifting and lowering of the rust removal machine. At the same time, because a counterweight 6 is set to balance the pressure, the drive mechanism 2 is subjected to more even force, which makes it more stable during operation and less prone to tipping over.

[0043] In a further embodiment, the drive mechanism 2 includes two fixed plates 201 fixedly connected to the fixed base 1. A first motor 202 is provided on one side of the fixed plate 201. The first motor 202 is preferably a servo motor with a reducer, and is connected and controlled in an existing manner.

[0044] The output shaft of the first motor 202 is provided with a rotating shaft 203;

[0045] The rotating shaft 203 is equipped with a conveying roller 204, which is located between two fixed plates 201;

[0046] Cable 3 is wrapped around conveyor roller 204. The number of turns of cable 3 around conveyor roller 204 is 1-3 to ensure that there is sufficient friction between cable 3 and conveyor roller 204.

[0047] In use, starting the first motor 202 can drive the rotating shaft 203 to rotate, which in turn drives the conveyor roller 204 to rotate. The rotation of the conveyor roller 204 will cause the wound cable 3 to move, so that one side of the cable 3 is wound around the conveyor roller 204 and the other side is away from the conveyor roller 204, thereby driving the movable seat 4 to rise and fall.

[0048] In a further embodiment, the fixed base 1 is provided with a plurality of guide rollers 7, the cable 3 passes around the guide rollers 7, and preferably passes over the top of the guide rollers 7, in order to determine the position of the cable 3.

[0049] In the preferred embodiment, the counterweight 6 and the movable seat 4 are provided with hooks on their tops, and the two ends of the cable 3 are provided with connecting hooks, which are connected to the hooks.

[0050] Therefore, during use, cable 3 can be connected to counterweight 6 and movable seat 4 by means of hook, which facilitates connection and disassembly during use.

[0051] Example 2:

[0052] like Figure 1 , 2 As shown in Figures 3 and 4, the fixed base 1 is provided with a recycling mechanism 5. The recycling mechanism 5 includes two support plates 501. A second motor 502 is provided on one side of the support plate 501. The output shaft of the second motor 502 is provided with a movable shaft 503. The second motor 502 is preferably a servo motor with a reducer, which is connected and controlled in an existing manner.

[0053] The movable shaft 503 is equipped with a winding roller 504, which is located between two support plates 501.

[0054] The circumferential surface of the winding roller 504 is provided with a through hole 505 that passes through the winding roller 504. The cable 3 passes through the through hole 505, and the width of the through hole 505 is greater than the diameter of the cable 3.

[0055] During normal use, cable 3 passes through the through hole 505, and the second motor 502 stops, thus not affecting the movement of cable 3 during the lifting and lowering of the movable seat 4. During the installation process after or before the rust removal work is completed, the lengths of the two ends of cable 3 below the fixed seat 1 are made similar, that is, the heights of the two ends of cable 3 are similar. Then, the second motor 502 is started to drive the movable shaft 503 to rotate, which in turn drives the winding roller 504 to rotate. Then, cable 3 can be wound onto the winding roller 504, which restricts the movement of cable 3. Then, the winding roller 504 continues to rotate until both ends of cable 3 are close to the top of the gate, which makes it easy for the staff to disassemble and assemble the counterweight 6 and the movable seat 4. Conversely, the winding can be canceled without affecting the movement of the cable.

[0056] In a preferred embodiment, the top of the counterweight 6 is provided with a pull ring 601, which facilitates the connection and hooking of the counterweight.

[0057] In a further embodiment, the circumferential surface of the winding roller 504 is provided with a threaded hole 506, which communicates with the through hole 505.

[0058] The threaded hole 506 is internally threaded to a limiting post 507, and the limiting post 507 is externally provided with a thread that is compatible with the threaded hole 506.

[0059] The limiting post 507 has a limiting protrusion at one end near the through hole 505, and the other end of the limiting post 507 has an internal hexagonal hole 508. The size of the internal hexagonal hole 508 is compatible with the size of existing hexagonal wrenches.

[0060] When it is necessary to wind the cable 3, insert a hex wrench into the internal hexagonal hole 508 and turn it to drive the limiting post 507 to rotate. This causes the limiting post 507 to move under the action of the threaded hole 506, so that the limiting post 507 moves to block the cable 3, thereby completing the limitation of the cable 3, so that the winding roller 504 can rotate to wind the cable 3. When it is not necessary to wind, loosen the limiting post 507.

[0061] The movable seat 4 is equipped with several guide wheels 401 on the side near the rust-removing gate. These guide wheels are used to stabilize the movement of the movable seat 4 when it is raised or lowered, and to prevent the movable seat 4 from directly contacting the gate.

[0062] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
