Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a modular hoisting device for flood interception ditches. Background Technology

[0002] Interception ditches are water conservancy facilities used to intercept runoff from hillsides or surfaces. Their core function is to prevent soil erosion and flood disasters. They are widely used in road engineering, urban flood control, and landfills. Interception ditches are constructed using materials such as precast concrete modular components. The cross-sectional shape is usually trapezoidal. When the ground slope is steep, a rectangular structure may be used. Lifting equipment is required to lift them. The existing patent authorization announcement number CN220578729U discloses a precast component hoisting device. By setting a fixing component and a fixing plate, when the worker places the precast component inside the slot block during the hoisting process, the worker rotates the fixing plate to drive the clamp plate to fix the precast component, thereby facilitating the worker to fix the precast component and avoiding the situation where the precast component accidentally slips during the hoisting process. When using the aforementioned patent, the clamping plate and screw are located below the slot block. The precast concrete component needs to be fixed inside the slot block before hoisting. When the precast concrete component is lowered, the fixing plate is located below the precast concrete component and touches the ground first before the component, making it inconvenient to lower the component. This has significant limitations for operation of heavier precast components and reduces the ease of use. Utility Model Content

[0003] The purpose of this utility model is to provide a modular hoisting device for flood interception ditches, so as to solve the problem in the above-mentioned background technology that when the precast concrete component is lowered, the fixing plate is located below the precast concrete component and contacts the ground before the component, which makes it inconvenient to lower the component. This has a great limitation on the operation of heavier components and reduces the convenience of use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modular hoisting device for a flood interception ditch, comprising a hoisting frame, wherein two sliding grooves are symmetrically arranged front and back inside the hoisting frame, and multiple limiting adjustment holes are symmetrically arranged front and back at equal intervals on the top of the hoisting frame, wherein two hoisting components are movably engaged inside the two sliding grooves, and a groove is provided in the center of the bottom of the hoisting frame, wherein a stabilizing component is provided inside the groove; the hoisting component includes a sliding seat movably engaged inside the sliding groove, wherein a limiting hole corresponding to the limiting adjustment hole is provided on the top of the sliding seat, and a limiting pin is provided on the top of the hoisting frame that penetrates the limiting adjustment hole and engages in the limiting hole, wherein two lifting rings are fixedly connected to the bottom of the sliding seat and are symmetrically arranged left and right, and two hoisting ropes are hung outside the two lifting rings, wherein a hook is fixedly connected between the two hoisting ropes.

[0005] Preferably, multiple rollers are movably mounted on both the left and right sides of the sliding seat, and the multiple rollers are all located inside the sliding groove.

[0006] Preferably, a rubber block is fixedly installed at the bottom of the limiting pin.

[0007] Preferably, the limiting adjustment holes are arranged symmetrically along the length of the sliding groove.

[0008] Preferably, the stabilizing component includes a bidirectional lead screw rotatably mounted inside the groove. The external thread of the bidirectional lead screw is connected to two sliders symmetrically arranged on the left and right. The bottom of each of the two sliders is movably hinged to two intermediate rods. The ends of the two intermediate rods away from the sliders are movably hinged to stabilizing pressure plates. One end of the bidirectional lead screw is fixedly connected to a handle located outside the hoisting frame.

[0009] Preferably, a protective pad is fixedly installed at the bottom of the stabilizing pressure plate.

[0010] Preferably, the stabilizing pressure plate is located at the center of the bottom of the hoisting frame, and the stabilizing pressure plate is vertically downward.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When using, place the two hoisting ropes at the symmetrical ends of the bottom of the precast concrete component to be hoisted, and hook the hooks at both ends of the hoisting ropes onto the lifting rings on the left and right sides of the bottom of the sliding seats to facilitate hoisting. After hoisting to the construction position, lower the precast concrete component, remove the hooks from the lifting rings, and then pull the hoisting ropes out from under the precast concrete component. The whole operation is more convenient and easy to use. 2. By rotating the handle, the double-sided lead screw in the groove is rotated. The rotation of the double-sided lead screw causes the sliders on the left and right sides to slide closer to each other, which in turn pushes the middle rod to move. This pushes the stabilizing pressure plate down to contact the top of the precast concrete component, applying pressure from top to bottom, thereby reducing the shaking of the precast concrete component and enhancing its stability during hoisting.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a modular hoisting device for a flood interception ditch, comprising a hoisting frame 1, with two symmetrically arranged sliding grooves 2 inside the hoisting frame 1, and multiple symmetrically arranged limiting adjustment holes 3 at equal intervals on the top of the hoisting frame 1. Two hoisting components 4 are movably engaged inside the two sliding grooves 2. A groove 5 is centrally located at the bottom of the hoisting frame 1, and a stabilizing component 6 is arranged inside the groove 5. The hoisting component 4 includes a sliding seat 41 movably engaged inside the sliding groove 2, with a limiting hole 42 corresponding to the limiting adjustment hole 3 on the top of the sliding seat 41. A limiting pin 43 penetrates the limiting adjustment hole 3 and engages within the limiting hole 42 on the top of the hoisting frame 1. Two symmetrically arranged lifting rings 45 are fixedly connected to the bottom of the sliding seat 41, and two hoisting ropes 46 are hung outside the two lifting rings 45. Two hoisting ropes 46 are fixedly connected with hooks 47. The two hoisting ropes 46 are placed at the symmetrical ends of the bottom of the precast concrete component to be hoisted. The limiting pin 43 is pulled out from the limiting adjustment hole 3, allowing the sliding seat 41 to slide inside the sliding groove 2. After the sliding seat 41 is adjusted to a position that matches the hoisting ropes 46 by sliding in the sliding groove 2, the limiting pin 43 is passed through the limiting adjustment hole 3 that matches the current position of the limiting hole 42, and then inserted into the limiting hole 42 to limit the sliding seat 41. The hooks 47 at both ends of the hoisting ropes 46 are respectively hung on the lifting rings 45 on the left and right sides of the bottom of the sliding seats 41 on both sides, and then hoisting is carried out. After hoisting to the construction position, the precast concrete component is lowered. The hooks 47 on both sides can be removed from the lifting rings 45, and the hoisting ropes 46 can be pulled out from under the precast concrete component. The whole operation is more convenient and easy to use.

[0016] Multiple rollers 44 are movably mounted on both the left and right sides of the sliding seat 41. The rollers 44 are all located inside the sliding groove 2. The rollers 44 can roll along the inner wall of the sliding groove 2, which effectively reduces the friction when the sliding seat 41 slides in the sliding groove 2, making the position adjustment process of the sliding seat 41 smoother and avoiding the situation where the sliding seat 41 gets stuck or is difficult to adjust due to excessive friction. At the same time, it also reduces the wear between the sliding seat 41 and the sliding groove 2, which helps to extend the service life of the device.

[0017] A rubber block 48 is fixedly installed at the bottom of the limiting pin 43. The diameter of the hole in the rubber block 48 is slightly larger than that in the limiting hole 42. When the limiting pin 43 is inserted into the limiting hole 42, the rubber block 48 will make close contact with the edge of the limiting hole 42. By utilizing the elasticity and friction of the rubber material itself, the stability of the limiting pin 43 in the limiting hole 42 is further enhanced, preventing the limiting pin 43 from accidentally loosening or falling off due to vibration or other factors during hoisting. This ensures that the sliding seat 41 is reliably fixed and improves the safety of the entire hoisting device during use.

[0018] The limiting adjustment holes 3 are symmetrically arranged on the left and right sides along the length of the sliding groove 2. The diameter of the limiting adjustment holes 3 is adapted to the limiting holes 42. The spacing between two adjacent limiting adjustment holes 3 is equal. The uniformly distributed design allows the sliding seat 41 to be fixed according to the actual hoisting requirements when adjusting its position in the sliding groove 2, thereby achieving precise adjustment of the position of the sliding seat 41 and improving the applicability and flexibility of the hoisting device.

[0019] Please see Figure 1 , Figure 2 and Figure 5 The stabilizing component 6 includes a bidirectional lead screw 61 rotatably installed inside the groove 5. The external thread of the bidirectional lead screw 61 is connected to two sliders 62 symmetrically arranged on the left and right. The bottom of the two sliders 62 is movably hinged to two intermediate rods 63. The ends of the two intermediate rods 63 away from the sliders 62 are movably hinged to stabilizing pressure plates 64. One end of the bidirectional lead screw 61 is fixedly connected to a handle 65 located outside the hoisting frame 1. When the precast concrete component is first hoisted, the handle 65 is rotated, which drives the bidirectional lead screw 61 in the groove 5 to rotate. The rotation of the bidirectional lead screw 61 causes the sliders 62 on the left and right sides to slide closer to each other, thereby pushing the intermediate rods 63 to move and pushing the stabilizing pressure plate 64 to move downward. The stabilizing pressure plate 64 moves downward and contacts the top of the precast concrete component, applying pressure from top to bottom, thereby reducing the swaying of the precast concrete component and enhancing its stability during hoisting.

[0020] A protective pad 66 is fixedly installed at the bottom of the stabilizing plate 64. The protective pad 66 is made of high-density rubber material and has anti-slip texture on its surface, which can effectively increase the friction between the stabilizing plate 64 and the precast concrete component, further improving the anti-slip effect. The rubber material has good elasticity and cushioning performance. When the stabilizing plate 64 comes into contact with the precast concrete component, the protective pad 66 can prevent the metal stabilizing plate 64 from making direct hard contact with the concrete surface, preventing indentations or damage to the surface of the precast concrete component, and playing a role in protecting the appearance quality of the precast concrete component.

[0021] The stabilizing pressure plate 64 is located at the center of the bottom of the hoisting frame 1. The stabilizing pressure plate 64 is set vertically downwards. Its length is adapted to the lateral span of the hoisting frame 1, and its width is designed according to the common size of the precast concrete component to ensure that it can form a uniform coverage on the top of the precast component and ensure a stable pressing effect on the precast concrete component.

[0022] Working principle: During use, two hoisting ropes 46 are positioned symmetrically at the bottom of both ends of the precast concrete component to be hoisted, ensuring that both ends are as equal in length as possible. Then, the limiting pin 43 is pulled out from the limiting adjustment hole 3, and the sliding seat 41 slides along the inside of the sliding groove 2. The sliding seat 41 is adjusted within the sliding groove 2 to a position suitable for the hoisting ropes 46. Subsequently, the limiting pin 43 is passed through the limiting adjustment hole 3, which is now aligned with the position of the limiting hole 42, and inserted into the limiting hole 42 to limit the sliding seat 41, thus hoisting the concrete component. The hooks 47 at both ends of the rope 46 are respectively hung on the lifting rings 45 on the left and right sides of the bottom of the sliding seats 41 on both sides. Then, the hoisting frame 1 is lifted by the hoisting vehicle using the lifting holes at the top of the hoisting frame 1. The hoisting ropes 46 located at both ends of the concrete precast component ensure the stable hoisting of the concrete precast component. After the concrete precast component is hoisted to the construction position, it is lowered. The hooks 47 on both sides can be removed from the lifting rings 45, and then the hoisting ropes 46 can be pulled out from under the concrete precast component. The overall operation is more convenient and easier to use. When the precast concrete component is initially lifted, the handle 65 is turned, which drives the bidirectional lead screw 61 in the groove 5 to rotate. The rotation of the bidirectional lead screw 61 drives the sliders 62 of the left and right parts to slide closer to each other, thereby driving the middle rod 63 to move and push the stabilizing pressure plate 64 downward. The downward movement of the stabilizing pressure plate 64 contacts the top of the precast concrete component and applies a downward force to it, reducing the swaying of the precast concrete component and improving the stability of the precast concrete component during lifting. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
