Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and more specifically, to a hoisting and construction device for prefabricated channels. Background Technology

[0002] With the trend of modern civil engineering towards industrialization, standardization, and efficiency, traditional cast-in-place channel construction requires a series of complex processes on-site, including formwork, rebar tying, concrete pouring, and curing. This not only results in long construction cycles and high labor demands but is also significantly affected by weather, making precise quality control difficult. Construction of irrigation canals in farmland is particularly inconvenient due to narrow and often muddy paths. To overcome these drawbacks, prefabricated building technology has rapidly developed. Precast channels are mass-produced in factories and then installed into pre-excavated trenches using specialized hoisting equipment. This significantly shortens the construction period, improves efficiency, and reduces dependence on the site environment and impact on surrounding traffic. Hoisting equipment for precast channels typically includes a hoisting frame, hoisting ropes, and a lifting device. In practice, the precast channel components are secured with hoisting ropes, then the ropes are attached to the lifting device on the hoisting frame. Activating the lifting device allows for the lifting and installation of the precast channel components.

[0003] However, the aforementioned technologies have the following drawbacks: during the hoisting process, precast channel components require real-time adjustments to their positions to ensure they are accurately hoisted to their designated locations. This minimizes the gap between the precast channel components and the previous ones, preventing leakage during subsequent channel use. However, precast channel components are cast from concrete and are large in size and weight, making manual adjustment of their hoisting positions extremely difficult. This not only increases the difficulty of construction but also raises the risks for workers. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated channel hoisting construction device, which can reduce construction difficulty, ensure accurate hoisting of prefabricated channel components, and reduce construction risks.

[0016] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0017] 1. Assuming the pre-installed channel component is located on the left, this invention uses a hoisting rope assembly on two mounting frames to hoist the channel component. First, the channel component in the air is positioned with the left side lower than the right side, so that the left sidewall of the channel component first abuts against the right top edge of the previously installed channel component, forming a line-surface contact. Then, the right side of the channel component is gradually lowered until the sidewalls of the two channel components are completely in contact. Finally, the hoisting frame is lowered to complete the hoisting of the channel component. This ensures the hoisting accuracy of the channel component. At the same time, during the hoisting process, there is no need for workers to manually adjust the air position of the channel component, which reduces the construction difficulty and also reduces the construction risk.

[0018] 2. This invention uses a connector to spirally braid the first and second lifting ropes in the same lifting rope assembly to form a rope structure, which can effectively improve energy absorption and the toughness of the lifting rope assembly during the lifting process. Energy is absorbed through the friction between the first and second lifting ropes, resulting in better toughness and impact resistance. At the same time, a connecting hole is formed between the first and second lifting ropes after weaving. When the connector is inserted into the connecting hole, the angle position of the channel component can be adjusted along the axial direction with the length direction of the installation part as the installation part rotates, so that the channel component is in a horizontal state during the lifting process, further improving the lifting accuracy of the channel component.

[0019] 3. This invention uses a first and second lifting rope in the same lifting rope assembly to wrap around different positions of the channel component, which can further improve the fixing stability of the channel component during the hoisting process. On this basis, by setting a connector, the position of the connector on the first and second lifting ropes can be flexibly adjusted according to the channel component with different weights, sizes and models. At the same time, the pitch of the spiral braid of the first and second lifting ropes above the connector, which is also the size of the connection hole, can be adjusted, thereby effectively improving the applicability of the lifting rope assembly to different channel components.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0032] Example

[0033] The following is for reference Figures 1-9 As shown in the figure, and further illustrated with specific embodiments, this embodiment provides a prefabricated channel hoisting and construction device.

[0034] Reference Figure 1 and Figure 2 A prefabricated channel hoisting construction device includes a hoisting frame 1, and an installation frame 2 is slidably arranged on the hoisting frame 1 along the length direction of the hoisting frame 1. There are two installation frames 2, and each installation frame 2 is equipped with a hoisting rope assembly 3.

[0035] As one possible implementation of the present invention, the lifting frame 1 can be installed on a crane or other lifting entity. The specific installation position is not specifically limited, as long as it can drive the lifting frame 1 to move. This is the prior art and will not be described in detail here.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The suspension rope assembly 3 includes a first suspension rope 31, a second suspension rope 32, and a connector 33. The mounting bracket 2 is provided with a mounting part 21. The bottom end of the first suspension rope 31 is wound around the bottom of the channel component, and the top end is wound around the mounting part 21. The bottom end of the second suspension rope 32 is wound around the side of the channel component, and the top end is wound around the mounting part 21. The connector 33 is sleeved on the first suspension rope 31 and the second suspension rope 32. The connector 33 acts on the first suspension rope 31 and the second suspension rope 32 so that the first suspension rope 31 and the second suspension rope 32 are arranged in parallel.

[0037] Among them, reference Figure 2 The hoisting frame 1 is equipped with a first driving device 4, which is used to drive the mounting frame 2 to move in a direction that is closer to or further away from each other on the hoisting frame 1.

[0038] As one embodiment of the present invention, refer to Figure 2 The first driving device 4 includes a first driving motor 41, a second driving motor 42, a first lead screw 43, and a second lead screw 44. A first sliding groove 45 and a second sliding groove 46 are horizontally formed at the bottom of the hoisting frame 1, located on opposite sides of the hoisting frame 1. The first sliding groove 45 and the second sliding groove 46 have the same length. Two first sliders 47 are slidably disposed within the first sliding groove 45, and two second sliders 48 are slidably disposed within the second sliding groove 46. The top of each mounting frame 2 is fixedly connected to one first slider 47 and one second slider 48. The first lead screw 43 is rotatably disposed within the first sliding groove 45, and the second lead screw 44 is rotatably disposed within the second sliding groove 46. The first driving motor 41 and the second driving motor 42 are both fixedly mounted on the side wall of the hoisting frame 1. The output shaft of the first driving motor 41 is connected to the first lead screw 43 via a coupling, and the output shaft of the second driving motor 42 is connected to the second lead screw 44 via a coupling.

[0039] In one embodiment of the present invention, a first slider 47 on one mounting bracket 2 is threaded onto a first lead screw 43, and a second slider 48 is slidably mounted onto a second lead screw 44; a first slider 47 on another mounting bracket 2 is slidably mounted onto a first lead screw 43, and a second slider 48 is threaded onto a second lead screw 44.

[0040] By adopting the above technical solution, in actual use, it is assumed that the pre-installed channel component is located on the left side of the channel component to be hoisted. During hoisting, the bottom end of the first hoisting rope 31 is wrapped around the bottom of the component, and the bottom end of the second hoisting rope 32 is wrapped around the side of the component. Since the two mounting frames 2 are driven independently by the first screw 43 and the second screw 44 respectively, the two mounting frames 2 can move independently and there is no movement linkage between them. At this time, one or both of the first drive motor 41 or the second drive motor 42 are started to adjust the position of one or two mounting frames 2 on the hoisting frame 1. Since the length of the first hoisting rope 31 and the second hoisting rope 32 only has a slight deformation, and the second hoisting rope 32 has already wrapped around both sides of the channel component, the hoisted channel component will be in a state of left lower and right higher as the mounting frame 2 moves. Under the lifting and wrapping action of the second hoisting rope 32, the channel component can be prevented from slipping in the left and right directions on the hoisting rope.

[0041] At this point, by moving the hoisting frame 1, the left side wall of the channel component to be hoisted first comes into contact with the right top edge of the previously installed channel component, forming a line-surface contact. Then, by moving one or two mounting frames 2, the right side of the channel component is gradually lowered until the side walls of the two channel components are completely fitted together. Then, the hoisting frame 1 is lowered again to complete the hoisting of the channel component. This effectively ensures the hoisting accuracy of the channel component. At the same time, during the hoisting process, the gravity of the channel component itself achieves the fitting of the component to be hoisted with the already hoisted component, eliminating the need for manual intervention by workers, significantly reducing the difficulty of construction, and also effectively reducing construction risks.

[0042] As one embodiment of the present invention, refer to Figure 3 , Figure 4 and Figure 5 In the same lifting rope assembly 3, the first lifting rope 31 and the second lifting rope 32 are two independent lifting ropes. During the lifting process, the first lifting rope 31 and the second lifting rope 32 are connected to the side wall of the channel component through the connector 33, forming a rope structure with a separate bottom and a spiral braided top. The separate bottom design allows the first lifting rope 31 to provide lifting force to the channel component, while the second lifting rope 32 wraps around the side of the channel component to prevent lateral slippage during tilting. The spiral braided top design makes the first lifting rope 31 and the second lifting rope 32 form a tightly integrated whole, effectively preventing slippage during lifting and forming a stable lifting rope combination. Compared with the simple parallel arrangement of the first lifting rope 31 and the second lifting rope 32, the spiral braid can withstand greater elongation. Energy is absorbed through the adjustment of the spiral braid structure and the friction between the first lifting rope 31 and the second lifting rope 32, resulting in better toughness and impact resistance.

[0043] At the same time, refer to Figure 4 A plurality of connecting holes 5 are formed between the first spirally woven suspension rope 31 and the second suspension rope 32, and the mounting part 21 is rotatably mounted on the mounting frame 2. A connector 51 is provided on the mounting part 21. As one embodiment of the present invention, see reference to Figure 4 The connector 51 is configured as a plug, which is inserted into the connector hole 5. At the same time, a drive component 6 is provided on the mounting bracket 2, which is used to drive the mounting part 21 to rotate.

[0044] In actual use, after the channel component is hoisted into the air, the channel component will inevitably deflect at an angle along its length axis. At this time, the drive component 6 drives the installation part 21 to deflect, which in turn drives the connector 51 to deflect. Since the connector 51 is inserted into the connection hole 5, the deflection of the connector 51 drives the first hoisting rope 31 and the second hoisting rope 32 to move. This allows for the adjustment of the angle deflection of the channel component along its length axis, thereby ensuring that the channel component is in a horizontal state during hoisting and further ensuring the hoisting accuracy of the channel components after they are lowered.

[0045] Reference Figure 3 In one embodiment of the present invention, the driving member 6 is configured as a rotary motor. A sliding part 61 is slidably disposed at the bottom of the mounting bracket 2 in a horizontal direction, and a mounting part 21 is rotatably disposed on one side of the sliding part 61. A mounting groove 62 is provided in the sliding part 61, the driving member 6 is disposed in the mounting groove 62, and the mounting part 21 is disposed on the output shaft of the driving member 6.

[0046] Reference Figure 3 An abutment portion 63 is fixedly provided at the bottom of the mounting bracket 2. A receiving groove 64 is provided on the side wall of the abutment portion 63 near the sliding portion 61. A rotating groove 65 is rotatably provided on the bottom wall of the receiving groove 64. The diameter of the rotating groove 65 is larger than that of the receiving groove 64. A rotating plate 66 is rotatably provided in the rotating groove 65. An abutment member 67 is rotatably provided at one end of the abutment portion 63 near the sliding portion 61. As an embodiment of the present invention, the abutment member 67 is set as an abutment plate. A first elastic member 68 is fixedly connected between the abutment member 67 and the rotating plate 66.

[0047] Reference Figure 3 In one embodiment of the present invention, the first elastic element 68 is configured as a compression spring, and three first elastic elements 68 are provided. The three first elastic elements 68 are evenly arranged along the circumference of the rotating plate 66. In other possible embodiments of the present invention, one, two, four or other quantities of first elastic elements 68 may be provided, as long as they can provide stable and uniform elastic support for the abutment 67.

[0048] Reference Figure 3 As one embodiment of the present invention, a ball bearing is embedded on the side wall of the rotating plate 66 away from the abutment member 67, and the ball bearing is used to roll in contact with the inner wall of the rotating groove 65.

[0049] Reference Figure 3A second driving device 7 is provided on the mounting frame 2. The second driving device 7 is used to drive the sliding part 61 to move on the mounting frame 2. As an embodiment of the present invention, the second driving device 7 includes an adjusting motor 71 and an adjusting screw 72. An adjusting groove 73 is provided at the bottom of the mounting part 21. An adjusting block 74 is slidably arranged in the adjusting groove 73. The adjusting motor 71 is fixedly arranged on the mounting part 21. The adjusting screw 72 is rotatably arranged in the adjusting groove 73. The adjusting block 74 is threadedly sleeved on the adjusting screw 72. The adjusting screw 72 is connected to the output shaft of the adjusting motor 71. The bottom of the adjusting block 74 is fixedly connected to the sliding part 61.

[0050] In actual use, during the hoisting of the channel components, the second drive device 7 first drives the sliding part 61 to move towards the abutment part 63, so that the side wall of the mounting part 21 abuts against the abutment part 67, and compresses the first elastic member 68 to a fully compressed state. At this time, the hoisting rope assembly 3 passes around the mounting part 21. As the mounting part 21 rotates, the hoisting rope assembly 3 moves, adjusting the aerial hoisting state of the channel components. At this time, the mounting part 21 and the abutment part 67 are in close contact, which can prevent the hoisting rope assembly 3 from detaching. After the hoisting of the channel components is completed, the second drive device 7 drives the sliding part 61 away from the abutment part 63, so that the side wall of the mounting part 21 is no longer in contact with the abutment part 67. At this time, since the channel components have been hoisted, the hoisting rope assembly 3 no longer bears tension. As the mounting part 21 moves, a gap appears between the mounting part 21 and the abutment part 67, and the workers can remove the hoisting rope from the mounting part 21, and then remove the hoisting rope from the channel components through the side or bottom edge, realizing the reuse of the hoisting rope assembly 3.

[0051] Reference Figure 5 and Figure 6 The connector 33 includes a first connecting portion 34 and a second connecting portion 35. The second connecting portion 35 is rotatably mounted on the first connecting portion 34 in a vertical direction. A through hole 36 is formed in the first connecting portion 34 in a vertical direction for the first lifting rope 31 and the second lifting rope 32 to pass through. A first through hole 37 and a second through hole 38 are formed in the second connecting portion 35 in a vertical direction. The first through hole 37 is for the first lifting rope 31 to pass through, and the second through hole 38 is for the second lifting rope 32 to pass through. A limiting member 8 (such as...) is provided on the second connecting portion 35. Figure 8 As shown), the limiting member 8 is used to limit the deflection angle of the second connecting part 35.

[0052] Reference Figure 5 and Figure 6A roller 39 is rotatably disposed inside the through hole 36. There are two rollers 39. The two rollers 39 roll in contact with the first suspension rope 31 and the second suspension rope 32 respectively. The second connecting part 35 interweaves the first suspension rope 31 and the second suspension rope 32. The portions of the first suspension rope 31 and the second suspension rope 32 located above the connector 33 interweave to form a number of connecting holes 5.

[0053] In actual use, the first lifting rope 31, the second lifting rope 32, and the connector 33 form a whole lifting rope assembly 3. The lifting rope assembly 3 contains two connectors 33. During the lifting process, the two connectors 33 are located on both sides of the channel component. According to the size and model of the channel component being lifted, the position of the connectors 33 on the first lifting rope 31 and the second lifting rope 32 is adjusted. Then, the second connecting parts 35 of the connectors 33 on both sides of the channel component are rotated in opposite directions, so that the first lifting rope 31 and the second lifting rope 32 above the connectors 33 form a spiral braided shape. The specific way to rotate the second connecting parts 35 can be determined according to the actual use needs, either by manual rotation by the staff or by electric drive by an external motor. This is existing technology and will not be described in detail here.

[0054] During the hoisting process, since the channel components are made of concrete and are extremely heavy, the first hoisting rope 31 and the second hoisting rope 32 in the hoisting rope assembly 3 will be in a taut state. Therefore, before hoisting, the connecting hole 5 formed by the spirally braided first hoisting rope 31 and the second hoisting rope 32 needs to be inserted into the connector 51. At the same time, during hoisting, the connector 33 will be pressed against the side wall of the channel component by the taut first hoisting rope 31 and the second hoisting rope 32 under the action of the gravity of the channel component. In addition, since the limiting member 8 is provided on the second connection part 35, the connector 33 can be further prevented from shifting on the first hoisting rope 31 and the second hoisting rope 32.

[0055] Reference Figure 7 and Figure 8 In one embodiment of the present invention, the limiting member 8 is configured as an insert block, a sliding strip 81 is slidably disposed on the side wall of the second connecting part 35 in the vertical direction, the limiting member 8 is fixedly disposed at the bottom of the sliding strip 81 in the vertical direction, a limiting block 82 is fixedly disposed on the side wall of the first connecting part 34, a limiting hole 83 is provided on the limiting block 82 for the limiting member 8 to be inserted, and a second elastic member 84 is provided on the second connecting part 35. The second elastic member 84 acts on the sliding strip 81 so that the sliding strip 81 has a downward tendency.

[0056] Reference Figure 7 and Figure 8A strip groove 85 is provided vertically on the side wall of the second connecting part 35. A strip block 86 is slidably disposed in the strip groove 85. A sliding strip 81 is fixedly connected to the strip block 86. A first fixing hole 87 is provided horizontally on the strip block 86. A fixing strip 811 is slidably disposed on the sliding strip 81. One end of the fixing strip 811 is slidably disposed in the first fixing hole 87. A second fixing hole 88 is provided on the inner wall of the strip groove 85. The second fixing hole 88 is used for inserting the fixing strip 811.
