Description

Technical Field

[0001] This utility model relates to a hoisting device, specifically a triangular interlocking slope protection block hoisting device, belonging to the field of water conservancy and hydropower technology. Background Technology

[0002] Slope protection blocks are engineering components used to protect slopes and prevent soil erosion. They are usually made of concrete, stone, or eco-friendly materials.

[0003] A search revealed a triangular interlocking slope protection block hoisting device in Chinese Patent Publication No. CN216377150U. This invention utilizes four hoisting mechanisms to simultaneously hoist four triangular interlocking slope protection blocks. By cleverly leveraging the triangular structure and weight of the blocks, the four blocks are hoisted as a group, significantly improving on-site construction efficiency. Simply assemble the four blocks into a single flat section, and then use a hoisting device to directly engage and lock the blocks for lifting.

[0004] Although the above solution can simultaneously lift four triangular interlocking slope protection blocks using four lifting mechanisms, significantly improving construction efficiency, the lifting device in the above patent is difficult to fix the lifted slope protection blocks. It relies solely on the self-weight of the slope protection blocks and the mutual contact of the triangular structure. When the blocks are lifted, swayed, or tilted, displacement may occur between the blocks, leading to partial detachment from the lifting device. This risk is exacerbated, especially in environments with high-speed wind or mechanical vibration. Utility Model Content

[0005] The purpose of this utility model is to provide a triangular interlocking slope protection block hoisting device to solve the above-mentioned problems, thereby solving the problem of difficulty in fixing hoisted slope protection blocks in the prior art.

[0006] This utility model is achieved through the following technical solution: a triangular interlocking slope protection block hoisting device, including a first hydraulic cylinder, a first telescopic rod slidably connected to the inner side of the first hydraulic cylinder, a fixing mechanism provided at the lower end of the first telescopic rod, the fixing mechanism including a fixing sleeve fixedly connected to the lower end of the first telescopic rod, and a second hydraulic cylinder connected to the inner side of the fixing sleeve.

[0007] The inner side of the second hydraulic cylinder is slidably connected to a second telescopic rod, and the lower end of the second telescopic rod is fixedly connected to a fixing block. A first connecting rod is hinged to one side of the fixing block, and an expansion plate is hinged to the end of the first connecting rod away from the fixing block. A second connecting rod is hinged to one side of the expansion plate, and the end of the second connecting rod away from the control plate is hinged to one side of the fixing sleeve.

[0008] Preferably, the outer surface of the second telescopic rod is slidably connected to the inner wall of the fixed sleeve, the second telescopic rod passes through the fixed sleeve, the second telescopic rod is installed inside the fixed sleeve, and the fixed block can be pushed to move up and down by the second telescopic rod.

[0009] Preferably, a sliding column is fixedly connected to the upper end of the first hydraulic cylinder, and a groove is provided on the inner side of the sliding column. The first hydraulic cylinder is mounted on the sliding column, and the fixed mechanism can be adjusted by the sliding column.

[0010] Preferably, a spring is fixedly connected to the inner side of the groove, and a limit block is fixedly connected to the lower end of the spring. Under the elastic force of the spring itself, the limit block can be supported, thus playing a supporting role.

[0011] Preferably, the outer surface of the limiting block is slidably connected to the inner wall of the sliding column, and a fixed column is slidably connected to the outer surface of the sliding column. The sliding column is installed inside the fixed column, thereby enabling the fixing mechanism to be adjusted according to the size of the slope protection block.

[0012] Preferably, the lower surface of the fixed column is provided with a slot, and the inner side of the slot is inserted into the limiting block. The limiting block is installed in the slot, thereby fixing the sliding column.

[0013] Preferably, one end of the fixed column is hinged to a lifting rod, and the upper end of the lifting rod is fixedly connected to a lifting ring, which is installed on the lifting rod, so that the device can be lifted to install the slope protection block.

[0014] Preferably, an electric telescopic rod is hinged to the upper surface of the fixed column, and the fixed end of the electric telescopic rod is hinged to one side of the lifting rod. The electric telescopic rod can push the fixed column to adjust the angle, thereby enabling the slope protection blocks to be lifted and transported.

[0015] This utility model provides a triangular interlocking slope protection block hoisting device, which has the following beneficial effects:

[0016] 1. The hoisting device uses a fixed sleeve, a second hydraulic cylinder, a second telescopic rod, a fixed block, a first connecting rod, an expansion plate, and a second connecting rod in cooperation. When the second hydraulic cylinder drives the second telescopic rod to move downward, the fixed block drives the first connecting rod to move, causing the expansion plate to unfold outward and form a rigid support for the inner wall of the slope protection block. At the same time, the second connecting rod and the fixed sleeve form a triangular stable structure, which generates a self-locking effect during hoisting to ensure that the slope protection block will not fall off due to shaking.

[0017] 2. This hoisting device uses a combination of sliding columns, fixed columns, slots, grooves, springs, and limit blocks. The sliding columns can slide up and down within the fixed columns, allowing the hoisting device to adapt to the hoisting needs of slope protection blocks of different heights. By pressing the limit blocks and adjusting the position of the sliding columns, operators can quickly adjust the working height of the hoisting device, improving construction flexibility.

[0026] This utility model embodiment provides a triangular interlocking slope protection block hoisting device.

[0027] Example 1:

[0028] Please see Figure 1 The system includes a first hydraulic cylinder 1, with a sliding column 4 fixedly connected to the upper end of the first hydraulic cylinder 1. A groove 7 is provided on the inner side of the sliding column 4. The first hydraulic cylinder 1 is mounted on the sliding column 4. The sliding column 4 can drive the first hydraulic cylinder 1 to adjust according to the width of the slope protection block. The groove 7 on the inner side of the sliding column 4 facilitates the fixation of the sliding column 4 by the limiting block 9. A spring 8 is fixedly connected to the inner side of the groove 7. The lower end of the spring 8 is fixedly connected to the limiting block 9. Both the spring 8 and the limiting block 9 are installed in the groove 7. Under the elastic force of the spring 8, the limiting block 9 can be supported, so that the limiting block 9 can be inserted into the slot 6, thereby fixing the sliding column 4.

[0029] Please see Figure 4 The outer surface of the limiting block 9 is slidably connected to the inner wall of the sliding column 4. The outer surface of the sliding column 4 is slidably connected to the fixed column 5. When the scale needs to be adjusted, pressing the limiting block 9 can make the sliding column 4 slide inside the fixed column 5, thereby fixing the adjusted sliding column 4 and playing a fixing role. The upper surface of the fixed column 5 is hinged to an electric telescopic rod 11. The fixed end of the electric telescopic rod 11 is hinged to one side of the lifting rod 10. The electric telescopic rod 11 is installed on the fixed column 5 and the lifting rod 10. The angle of the fixed column 5 can be adjusted by the electric telescopic rod 11, so that the slope protection block can be hoisted according to the angle.

[0030] Example 2:

[0031] Please see Figure 2 One end of the fixed column 5 is hinged to a lifting rod 10, and the upper end of the lifting rod 10 is fixedly connected to a lifting ring 12. Both the fixed column 5 and the lifting ring 12 are installed on the lifting rod 10. The device can be suspended on the crane through the lifting ring 12, which facilitates the crane to lift the slope protection block. The fixed column 5 can be angled on the lifting rod 10, which is beneficial to the lifting efficiency. The lower surface of the fixed column 5 is provided with a slot 6. The inner side of the slot 6 is inserted into the limiting block 9. The fixed column 5 is provided with a slot 6. After the limiting block 9 is inserted into the slot 6, the adjusted sliding column 4 can be fixed, which plays a fixing role.

[0032] A first telescopic rod 2 is slidably connected to the inner side of the first hydraulic cylinder 1. An externally installed hydraulic pump connects to the oil inlet and outlet ports on the first hydraulic cylinder 1. The telescopic rod is pushed to extend and retract within the first hydraulic cylinder 1 by hydraulic oil. A fixing mechanism 3 is provided at the lower end of the first telescopic rod 2. The fixing mechanism 3 includes a fixing sleeve 301 fixedly connected to the lower end of the first telescopic rod 2. A second hydraulic cylinder 302 is connected to the inner side of the fixing sleeve 301. The first telescopic rod 2 is installed inside the first hydraulic cylinder 1. The first telescopic rod 2 can be pushed to extend and retract within the first hydraulic cylinder 1 by the hydraulic oil in the first hydraulic cylinder 1, thereby pushing the fixing mechanism 3 to fix the slope protection block.

[0033] Example 3:

[0034] Please see Figure 3The second hydraulic cylinder 302 has a second telescopic rod 303 slidably connected to its inner side. It is connected to the oil inlet and outlet of the first hydraulic cylinder 302 via an externally installed hydraulic pump. The telescopic rod is pushed to extend and retract within the first hydraulic cylinder 302 by hydraulic oil. The outer surface of the second telescopic rod 303 is slidably connected to the inner wall of the fixed sleeve 301. The second telescopic rod 303 passes through the fixed sleeve 301 and is installed inside the fixed sleeve 301. The fixed sleeve 301 can fix the second telescopic rod 303 during extension and retraction, preventing it from tilting and serving as a guide.

[0035] The lower end of the second telescopic rod 303 is fixedly connected to a fixing block 304. A first connecting rod 305 is hinged to one side of the fixing block 304. An expansion plate 306 is hinged to the end of the first connecting rod 305 away from the fixing block 304. A second connecting rod 307 is hinged to one side of the expansion plate 306. The end of the second connecting rod 307 away from the control plate is hinged to one side of the fixing sleeve 301. The fixing mechanism 3 can be inserted into the slope protection block by the first hydraulic cylinder 1 and the first telescopic rod 2. Then, the second telescopic rod 303 is pushed to extend and retract by the second hydraulic cylinder 302. When the second telescopic rod 303 extends and retracts, it can drive the fixing block 304 and the first connecting rod 305 to extend and retract, so that the first connecting rod 305 can push the expansion plate 306 to unfold. The expansion plates 306 on both sides can be locked into the fixing groove of the slope protection block, thereby preventing loosening during hoisting and playing a fixing role. The first hydraulic cylinder 1 and the second hydraulic cylinder 302 are both controlled by an externally installed hydraulic pump.

[0036] The first hydraulic cylinder 1, the second hydraulic cylinder 302, and the electric telescopic rod 11 in this application are all common electrical devices in the prior art, and their models or specific structures will not be described in detail in this application.

[0037] Working principle: The operator presses the limiting block 9 to disengage it from the slot 6 of the fixed column 5. At this time, the sliding column 4 can slide freely within the fixed column 5. According to the width requirement of the slope protection block, the position of the sliding column 4 is adjusted. After releasing the limiting block 9, the spring 8 pushes the limiting block 9 to automatically engage with the corresponding slot 6, completing the width locking. The first hydraulic cylinder 1 is activated, pushing the first telescopic rod 2 downward to extend it, causing the fixing mechanism 3 to descend to the center hole position of the slope protection block. The fixing sleeve 301 and the expansion plate 306 move down with the first telescopic rod 2 and are inserted into the triangular interlocking hole of the slope protection block. The second hydraulic cylinder 302 is activated, pushing the second telescopic rod 303 downward to move it, causing the fixing block 304 to move down. When the fixing block 304 moves down, the first connecting rod 305 pushes the expansion plate 306 outward to unfold tightly against the inner wall of the slope protection block. The second connecting rod 307 and the fixed sleeve 301 form a triangular stable structure, which generates a self-locking effect during hoisting to prevent the expansion plate 306 from retracting. The expansion plate 306 is completely attached to the inner wall of the slope protection block, forming a multi-point rigid support to ensure that there is no loosening during hoisting. By controlling the extension and retraction of the electric telescopic rod 11, the angle between the fixed column 5 and the lifting rod 10 is adjusted so that the slope protection block is kept horizontal or at a specific tilt angle to adapt to the installation requirements of the slope. The lifting ring 12 is connected to the crane hook to smoothly lift the slope protection block to the target position. The second hydraulic cylinder 302 retracts, driving the second telescopic rod 303 to move upward. The fixed block 304 pulls the expansion plate 306 back through the first connecting rod 305, detaching it from the inner wall of the slope protection block. The first hydraulic cylinder 1 retracts, lifting the fixing mechanism 3 as a whole to complete the unloading and ensure that the slope protection block will not fall off due to shaking.
