Description

Technical Field

[0001] The utility model relates to the technical field of fault self-locking of counterweight block energy storage equipment, in particular to a fault self-locking structure for a counterweight block gravity energy storage device. Background Art

[0002] Using a steel wire rope to pull the counterweight to lift and lower is one of the commonly used structures in contemporary counterweight energy storage equipment. The counterweight falls from a height, and during the falling process, the steel wire rope is used to pull the generator mechanism to rotate and generate electricity, thereby realizing energy conversion.

[0003] The existing counterweight energy storage device lacks a self-locking structure when the wire rope breaks. Once a fault such as a wire rope break occurs, the counterweight will lose control and fall to a low place. Utility Model Content

[0004] The utility model aims to provide a fault self-locking structure for a counterweight gravity energy storage device, which can self-lock the counterweight in time when a wire rope breaks, so as to prevent the counterweight from falling out of control to a low place.

[0007] By adopting the above-mentioned technical scheme, the deadweight of the counterweight block can be used to apply a force to one end of the linkage arm, thereby causing the other end of the linkage arm to squeeze the second hydraulic rod. Under the movement of the liquid guide tube, the hydraulic oil enters the interior of the first hydraulic rod. The extension of the two first hydraulic rods makes the two brake blocks approach each other and squeeze the brake seat to achieve self-locking operation.

[0008] Furthermore, a limit seat is fixedly connected to each of the four corner positions of the upper surface of the movable bottom frame, and a limit linkage block is fixedly connected to the side surface of the placement frame, and the limit linkage block is slidably installed inside the limit seat.

[0009] By adopting the above technical solution, it is ensured that in the process of pulling the placement frame to raise its height, the height of the movable bottom frame can be raised synchronously.

[0010] Furthermore, a limiting track is respectively arranged at the four corner positions of the movable bottom frame, and a sliding block is respectively fixedly connected to the four corner positions of the movable bottom frame, and the sliding block is slidably connected in the sliding groove of the limiting track.

[0011] By adopting the above technical solution, it is ensured that one end of the linkage arm and the placement frame can achieve stable linkage operation.

[0012] Furthermore, a plurality of mounting holes are arranged on the side surface of the position limiting track, and spring rings are fixedly installed inside the mounting holes.

[0013] By adopting the above technical solution, the movable bottom frame can be limited and blocked, ensuring that the movable bottom frame and the placement frame can move relative to each other.

[0014] Furthermore, the telescopic end of the second hydraulic rod is provided with an arc top structure, and the second hydraulic rod is distributed vertically.

[0015] By adopting the above technical solution, the force stability of the second hydraulic rod is ensured.

[0016] Furthermore, two brake seats are provided, and the two brake seats are symmetrically distributed at two sides of the movable bottom frame.

[0017] By adopting the above technical solution, the stability and effectiveness of self-locking are improved.

[0018] In summary, the beneficial technical effects of the utility model are:

[0019] The utility model can, when a fault such as wire rope breakage occurs, the pulling force of the wire rope on the placement frame disappears, and at this time the counterweight block and the placement frame generate downward pressure on one end of the linkage arm. Under the action of the lever principle, the other end of the linkage arm applies a force to the telescopic end of the second hydraulic rod, thereby squeezing out the hydraulic oil inside the second hydraulic rod, and the hydraulic oil enters the interior of the first hydraulic rod along the liquid guide tube. The first hydraulic rod is extended, so that the two brake pads are close to each other and squeeze the brake seat, thereby realizing self-locking operation, effectively preventing the counterweight block from falling out of control, and effectively improving the overall practicality and safety.

A limit seat 4 is fixedly connected to the four corner positions of the upper surface of the movable bottom frame 3. A limit linkage block 6 is fixedly connected to the side surface of the placement frame 5. The limit linkage block 6 is slidably installed inside the limit seat 4. When a fault such as a wire rope breakage occurs, the pulling force of the wire rope on the placement frame 5 disappears. At this time, the counterweight block and the placement frame 5 generate downward pressure on one end of the linkage arm 14. Under the action of the lever principle, the other end of the linkage arm 14 applies a force to the telescopic end of the second hydraulic rod 15, thereby squeezing the hydraulic oil inside the second hydraulic rod 15. The hydraulic oil enters the first hydraulic rod 10 along the liquid guide tube 12. The first hydraulic rod 10 is extended, so that the two brake pads 11 are close to each other and squeeze the brake seat 7, thereby realizing self-locking operation, which can effectively prevent the counterweight block from falling out of control, and the overall practicality and safety are effectively improved.

[0027] Reference Figure 1 A limiting track 1 is respectively arranged at the four corner positions of the movable bottom frame 3, and a slider is fixedly connected to the four corner positions of the movable bottom frame 3, and the sliding connection of the slider is in the slide groove of the limiting track 1. A plurality of mounting holes are arranged on the side surface of the limiting track 1, and a spring ring 2 is fixedly installed inside the mounting hole, wherein the limiting track 1 can be used to improve the stability of the movable bottom frame 3 during the up and down movement, and at the same time, the spring ring 2 is used to start a certain blocking effect on the movable bottom frame 3, so that the relative position of the movable bottom frame 3 and the placement frame 5 can be changed, thereby enabling the self-locking mechanism to be stably and flexibly triggered.

[0028] Working principle: When in use, the structure is first installed at the specified position. When the wire rope breaks, the traction of the wire rope on the placement frame 5 disappears. At this time, the placement frame 5 and the internal counterweight block fall together with the movable bottom frame 3. Since the sliding connection of the movable bottom frame 3 is in the slide groove of the limiting track 1, a plurality of spring coils 2 are installed on the side surface of the limiting track 1. Therefore, the spring coils 2 can block the movable bottom frame 3 to a certain extent, so that the relative position between the movable bottom frame 3 and the placement frame 5 moves. At this time, the placement frame 5 falls downward relative to the movable bottom frame 3. This process can One end of the linkage arm 14 generates a downward force. Since the middle outer part of the linkage arm 14 is rotationally connected to the movable bottom frame 3, under the action of the lever principle, the other end of the linkage arm 14 squeezes one end of the second hydraulic rod 15. At this time, the hydraulic oil inside the second hydraulic rod 15 enters the first hydraulic rod 10 along the liquid guide tube 12, and the first hydraulic rod 10 extends, thereby driving the two brake pads 11 to approach each other and squeeze the brake seat 7. At this time, the falling speed can be effectively decelerated, and finally locked on the brake seat 7 to achieve self-locking operation, thereby preventing the counterweight from falling out of control.

Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
