Description
Technical Field
[0001] This utility model relates to the technical field of precast block hoisting devices, and in particular to a hoisting device for precast concrete blocks for slope protection. Background Technology
[0002] Laying precast concrete blocks on slopes is a robust, durable, and prefabricated method used in water conservancy projects, particularly in areas prone to severe water erosion such as riverbank protection and lake embankments. The interlocking structure effectively resists water flow impact, preventing soil subsidence due to water erosion and seepage. The precast blocks laid on the slope form a sturdy "armor," directly bearing the impact of water flow and wind, protecting the underlying soil. However, the concrete blocks are typically transported to the top of the embankment by vehicles and then manually transferred to the construction surface. Since slopes are typically inclined, this process is inconvenient for workers, time-consuming, labor-intensive, and poses safety hazards. Utility Model Content
[0003] This utility model discloses a hoisting device for precast concrete blocks for slope protection, which solves the problems of inconvenience for workers to move precast blocks to the slope, the time-consuming and labor-intensive process, and the safety hazards involved.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A hoisting device for precast concrete blocks for slope protection includes a column, a cylindrical column rotatably connected to the top of the column, a horizontally fixed frame fixed on the cylindrical column, a movable block movable towards both ends of the fixed frame on the fixed frame, a rotating rod rotatably connected inside the movable block, and a locking component detachably connected to the movable block inside the fixed frame; a rotatable winding roller is provided on the cylindrical column, and a driving assembly for driving the winding roller to rotate is also provided on the cylindrical column, a hoisting rope is wound on the winding roller, and the top surface of the rotating rod is in contact with the hoisting rope; a movable assembly for driving the column to move is provided on the column.
[0005] Compared with the prior art, the present invention has the following beneficial effects: After moving the hoisting device to the designated position and adjusting the position of the moving block, the precast block is lifted by the hoisting rope. The cylinder is then rotated, causing the fixing frame to rotate as well, moving the precast block above the area of the slope where it needs to be laid. The drive assembly drives the winding roller to unwind the hoisting rope, causing the precast block to move downwards and be placed on the slope where it needs to be laid. When hoisting the second precast block, the position of the moving block is adjusted to change the landing point of the precast block after hoisting, ensuring it lands on another area of the slope where it needs to be laid. Before each hoisting of a precast block, the position of the moving block is adjusted to change the final landing point of the precast block, allowing several precast blocks to be placed on the slope where they need to be laid, enabling workers to directly lay the precast blocks on the slope. This invention allows precast blocks to be directly hoisted to the slope where they need to be laid, eliminating the need for manual handling by workers, reducing their workload, and improving the efficiency of precast block laying.

[0008] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0009] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a hoisting device for precast concrete blocks for slope protection, including a column 1, a cylinder 11 rotatably connected to the top of the column 1, a horizontally fixed frame 2 fixed on the cylinder 11, a movable block 3 movable towards both ends of the fixed frame 2 on the fixed frame 2, a rotating rod 31 rotatably connected inside the movable block 3, and a locking component detachably connected to the movable block 3 inside the fixed frame 2; a rotatable take-up roller 4 is provided on the cylinder 11, and a drive assembly for driving the take-up roller 4 to rotate is also provided on the cylinder 11, a hoisting rope 6 is wound on the take-up roller 4, and the top surface of the rotating rod 31 contacts the hoisting rope 6; a movable assembly for driving the column 1 to move is provided on the column 1. The drive assembly includes a motor 5, a circular plate 51 fixed on the rotating shaft of the motor 5, a circular block 41 rotatably connected to the circular plate 51 fixed at one end of the take-up roller 4, and the circular plate 51 and the circular block 41 are fixed together by bolts; a bearing plate 12 fixed on the cylinder 11 and fixed to the main body of the motor 5. The drive assembly includes a throttle 42, which is fixed to the end of the take-up roller 4 away from the circular block 41. A connecting frame 8 is fixed to the side of the cylinder 11 away from the fixed frame 2. A counterweight frame 81 is fixed to the connecting frame 8, and a power supply box 82 is fixed to the counterweight frame 81. A connecting rod 13 is fixed to the top of the cylinder 11, and two cables 14 are fixed to the connecting rod 13, which are respectively connected to the fixed frame 2 and the connecting frame 8. When precast blocks need to be hoisted, after the circular block 41 and the circular plate 51 are fixed together with bolts, the motor 5 is started to drive the winding roller 4 to rotate. The end of the winding roller 4 away from the motor 5 passes through the bearing plate 12 and is rotatably connected to the bearing plate 12. In the event of a power failure such as the battery in the power supply box 82 being dead during field operations, the bolts on the circular block 41 can be removed, so that the circular block 41 is no longer fixed to the circular plate 51. Then, the workers can rotate the handle 42 to rotate the winding roller 4 and wind or unwind the hoisting rope 6. According to the weight of the precast blocks to be hoisted, objects of corresponding weight can be placed in the counterweight frame 81 to keep the hoisting device balanced. The cable 14 can further increase the stability of the fixing frame 2 and the connecting frame 8. After the column 1 is moved to the top of the slope, the position is adjusted. The position of the moving block 3 on the fixed frame 2 is determined, and then the precast block is lifted by the lifting rope 6 (a hook can be set at the end of the lifting rope 6 away from the winding roller 4 so that the hook can lift the container containing the precast block); then the cylinder 11 is rotated so that the precast block is perpendicular to the slope. The power supply box 82 is also equipped with a control switch to control the motor 5 to turn on or off. After the power supply box 82 supplies power to the motor 5 (the motor 5 is a servo motor), the motor 5 starts to unwind the winding roller 4 onto the lifting rope 6, and the rotating rod 31 starts to rotate due to friction with the lifting rope 6. After the precast block moves downward, it is placed on the slope of the slope; then the cylinder 11 is rotated again so that the fixed frame 2 is perpendicular to the top of the slope. Then, according to the position of the precast block to be placed on the slope, the position of the moving block 3 is adjusted, and then the above operation is repeated to continue to lift the precast block.
[0010] like Figure 1 and Figure 2 As shown, the locking component includes a connecting plate 21 fixed inside the fixing frame 2. The top of the connecting plate 21 has a set of screw holes arranged in a straight line. The movable block 3 has an opening through which the connecting plate 21 passes. The top of the movable block 3 is threaded with a screw 33 that matches the screw hole on the top of the connecting plate 21. The movable block 3 is slidably connected inside the fixing frame 2. After adjusting the position of the movable block 3 by sliding it, rotating the screw 33 causes it to thread into a corresponding screw hole on the top of the connecting plate 21, thus fixing the movable block 3.
[0011] like Figure 1 and Figure 2 As shown, there are two movable blocks 3, and a fixing rod 34 is fixed between the two movable blocks 3. The side of the fixing frame 2 away from the column 1 is located between the two movable blocks 3. A reinforcing rod 7 is fixedly connected through the movable block 3 located outside the fixing frame 2. A recessed hole is opened at the end of the connecting plate 21 away from the column 1. One end of the reinforcing rod 7 passes through the fixing frame 2 and extends into the recessed hole, where it is slidably connected. The movable block 3 is U-shaped, and an auxiliary rod 32 located above the rotating rod 31 and holding the suspension rope 6 is rotatably connected to the inner side of the movable block 3. One movable block 3 is located inside the fixed frame 2, and the other movable block 3 is located outside the fixed frame 2. When it is necessary to lift the precast block to a position further away from the column 1, the end of the lifting rope 6 away from the motor 5 can be passed through the inside of the movable block 3 located outside the fixed frame 2, so that the lifting rope 6 contacts the top surface of the rotating rod 31 inside the movable block 3. Then, by moving the movable block 3 located inside the fixed frame 2, the movable block 3 located outside the fixed frame 2 is moved along with it by the fixed rod 34. After adjusting the position of the movable block 3, the precast block can be lifted. The block is placed on the slope of the slope, further away from the column 1; there are two fixing rods 34, which are distributed vertically, and the fixing frame 2 is located between the two fixing rods 34 to increase the stability of the two moving blocks 3. At the same time, the reinforcing rod 7 moves with the moving block 3 located outside the fixing frame 2. The reinforcing rod 7 cooperates with the connecting plate 21 to further increase the stability of the moving block 3 located outside the fixing frame 2; the bottom surface of the auxiliary rod 32 is in contact with the hoisting rope 6, and with the rotating rod 31, it can effectively limit the hoisting rope 6.
[0012] like Figure 1As shown, the movable component includes a fixed plate 9 fixed to the column 1, and a set of movable support legs 91 fixed to the bottom of the fixed plate 9. A connecting ring 10 located below the fixed plate 9 is threaded onto the column 1. A lifting ring 101 is fixed to the bottom of the connecting ring 10, and a stud 102 is threaded onto the lifting ring 101. A stop plate 103 is fixed to the bottom of the stud 102. The column 1 can be moved to a designated position by moving the support legs 91, and then the connecting ring 10 can be rotated to move the lifting ring 101 downward. The stud 102 drives the stop plate 103 (which is circular) to contact the ground, thus fixing the column 1. When the ground is uneven, the height of a certain stop plate 103 can be adjusted by rotating the corresponding stud 102 to better support the column 1.
[0013] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
