Description

Technical Field

[0001] This utility model relates to the field of building material hoisting technology, and in particular to a strip hoisting device. Background Technology

[0002] In the construction industry, paneling is widely used in interior and exterior walls, ceilings, and other applications due to its advantages such as lightweight, high strength, and environmental friendliness. Its installation efficiency and quality directly affect project progress and cost. Lifting equipment, as the core equipment for paneling installation, undertakes the crucial tasks of vertical transportation and precise positioning. Traditional lifting equipment uses wire ropes or hooks to hook one end of the paneling and lifts it vertically to the predetermined position. Workers at the predetermined position then install the paneling. However, with the promotion of prefabricated buildings and modular construction, the installed panels can be either vertical or horizontal, such as ceiling panels and horizontal partition panels. After lifting the paneling vertically to the predetermined position, if horizontal installation is required, manual adjustment of the paneling's posture is necessary. Due to the paneling's weight, workers need to slowly (to ensure safety) lower the paneling to a horizontal position, consuming a significant amount of time and effort, resulting in low installation efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a strip hoisting device, which solves the problem that in existing technologies, after the hoisting device hoists the strip to the predetermined position, workers need to spend a lot of time adjusting the posture of the strip for horizontal installation, resulting in low installation efficiency.

[0004] According to an embodiment of this utility model, a strip hoisting device includes a base, a winch, and a winding assembly. The base has wheels at its bottom and a support column fixed at its top. A cantilever is provided on one side of the top of the support column. Both the support column and the cantilever are provided with several fixed pulleys. The winch is fixedly mounted on the base and has a first pull rope wound on it. The free end of the first pull rope passes over several fixed pulleys and is connected to two branch ropes. The winding assembly is fixedly mounted on the cantilever and has a second pull rope wound on it. The free end of the second pull rope is also connected to two branch ropes. Each branch rope has a clamping assembly connected to its free end. The clamping assembly is used to clamp and fix the strip.

[0005] Compared with existing technologies, this utility model has the following advantages: By using wheels at the bottom of the base, the device can be easily moved to a predetermined position. The first pull rope wound on the winch passes over the support column and the fixed pulley on the cantilever and is connected to the clamping assembly through two support ropes. The two support ropes of the second pull rope wound by the winding assembly on the cantilever are also connected to clamping assemblies. The four clamping assemblies clamp and fix the four corners of the strip. By simultaneously starting the winch and the winding assembly to wind up the first and second pull ropes, the strip is hoisted to the predetermined height. To facilitate the adjustment of the strip's hoisting state by the workers during subsequent installation, the winch can be controlled to wind up or release the first pull rope, and the winding assembly can be controlled to wind up or release the second pull rope. This eliminates the need for workers to readjust the strip's posture after receiving it, saving time and reducing the workers' labor intensity, thus greatly improving the installation efficiency of the strip.

[0006] Furthermore, each clamping assembly includes: two clamping blocks arranged opposite each other, the two clamping blocks being detachably connected by a connector, and slots for inserting the feed bar being opened on opposite sides of the two clamping blocks, and a connecting ring on each clamping block.

[0007] Furthermore, the connector includes: at least one bolt, each clamping block having several through holes for the bolt to pass through, and one end of the bolt passing through two opposing clamping blocks and then being screwed with a nut.

[0008] Furthermore, each clamping block has an anti-slip rubber pad inside its slot.

[0009] Furthermore, the winding assembly includes: a mounting box, which is fixedly mounted at the bottom of the cantilever, a winding shaft is rotatably mounted inside the mounting box, a motor is fixedly mounted on the side wall of the mounting box, the output end of the motor is fixed to the winding shaft, a second pull rope is wound on the winding shaft, and an opening is provided at the bottom of the mounting box for the second pull rope to pass through.

[0010] Furthermore, the connecting ring includes a retaining ring and a connecting rod. One end of the connecting rod is fixedly connected to the retaining ring, and the other end of the connecting rod is connected to a sliding rod. Each clamping block is provided with a T-shaped groove for the sliding rod to slide. The T-shaped groove is arranged in an L-shape along the direction in which the two clamping blocks are opposite to each other.

[0011] Furthermore, each connecting rod is threadedly connected to the corresponding slide rod.

[0012] Furthermore, both the cantilever and the strut are telescopic rods. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a strip hoisting device, including a base 1, a winch 6, and a winding assembly. The base 1 is provided with a traveling wheel 2 at the bottom and a support column 3 fixedly provided at the top of the base 1. A cantilever 4 is provided on one side of the top of the support column 3. Both the support column 3 and the cantilever 4 are provided with a plurality of fixed pulleys 5. The winch 6 is fixedly installed on the base 1. A first pull rope 7 is wound on the winch 6. The free end of the first pull rope 7 passes over a plurality of fixed pulleys 5 and is connected to two branch ropes 8. The winding assembly is fixedly installed on the cantilever 4. A second pull rope 9 is wound on the winding assembly. Two branch ropes 8 are also connected to the free end of the second pull rope 9. A clamping assembly is connected to the free end of each branch rope 8. The clamping assembly is used to clamp and fix the strip. In this embodiment, when hoisting the strip, the clamping components on each rope 8 are clamped onto the strip, thereby fixing the strip to the corresponding first pull rope 7 and second pull rope 9. When hoisting the strip, if the installation state of the strip is vertical, the second pull rope 9 is released through the winding component, so that the end of the strip connected to the first pull rope 7 is at the top and the end of the strip connected to the second pull rope 9 is at the bottom, keeping the strip in a vertical state. If the installation state of the strip is horizontal, the second pull rope 9 is wound up through the winding component, so that the end of the strip connected to the first pull rope 7 and the end connected to the second pull rope 9 are horizontal. By winding and releasing the second pull rope 9 through the winding component, the hoisted strip can be adjusted to a horizontal or vertical state according to the installation needs, which is convenient for workers to install the strip after hoisting it into place. Workers do not need to spend too much time adjusting the state of the strip, saving a lot of time and improving the installation efficiency of the strip.

[0021] like Figure 4 and Figure 5 As shown, each clamping assembly further includes two opposing clamping blocks 10, which are detachably connected by a connector. Each clamping block 10 has a slot on its opposite side for the strip to be inserted. Each clamping block 10 also has a connecting ring. When clamping the strip, the clamping blocks 10 are assembled in pairs, with two clamping blocks 10 clamping one corner of the strip. A total of four sets of clamping blocks 10 clamp the four corners of the strip. When hoisting the strip, the winch 6 winds up the first pull rope 7, and the winding assembly winds up the second pull rope 9, thereby hoisting the strip as a whole to a predetermined high position.

[0022] like Figure 4 and Figure 5 As shown, the connecting component further includes: at least one bolt 11, and each clamping block 10 has several through holes for the bolt 11 to pass through. One end of the bolt 11 passes through two opposing clamping blocks 10 and is screwed with a nut 12. In this embodiment, each clamping block 10 has three through holes. When connecting two clamping blocks 10, one end of the bolt 11 is inserted from one through hole of clamping block 10 into the other through hole, and then tightened with a nut. The distance between the two clamping blocks 10 is adjusted according to the thickness of the strip to be clamped. Specifically, the two clamping blocks 10 are first clamped at any corner of the strip, at which point the corner of the strip is inserted into the slot of the clamping block 10, and then the two clamping blocks 10 are tightened with bolt 11 and nut 12. Subsequently, when clamping strips of the same thickness, the two connected clamping blocks 10 are simply clamped at the corner of the strip without needing to adjust the bolt 11 and nut 12 again.

[0023] like Figure 4 and Figure 5 As shown, each clamping block 10 is further provided with an anti-slip pad 13 in its slot. In order to make the clamping of the strip more stable when the two clamping blocks 10 clamp the strip, the anti-slip pad 13 is provided in the slot of the clamping block 10. The anti-slip pad 13 increases the friction between the strip and the strip, thereby achieving the purpose of stabilizing the lifting of the strip.

[0024] like Figure 3As shown, the winding assembly further includes: a mounting box 14, which is fixedly mounted at the bottom of the cantilever 4. A winding shaft 15 is rotatably mounted inside the mounting box 14. A motor 16 is fixedly mounted on the side wall of the mounting box 14. The output end of the motor 16 is fixed to the winding shaft 15. The second pull rope 9 is wound on the winding shaft 15. The bottom of the mounting box 14 has an opening for the second pull rope 9 to pass through. When changing the hoisting state of the strip, the motor 16 is started, and the motor 16 drives the winding shaft 15 to rotate. The winding shaft 15 winds up or releases the second pull rope 9, thereby causing the end of the strip connected to the second pull rope 9 to move up or down. At the same time, the winch 6 also releases or winds up the first pull rope 7, achieving the purpose of changing the hoisting state of the strip.

[0025] like Figure 4 and Figure 5 As shown, the connecting ring further includes a retaining ring 17 and a connecting rod 18. One end of the connecting rod 18 is fixedly connected to the retaining ring 17, and the other end of the connecting rod 18 is connected to a sliding rod 19. Each clamping block 10 has a T-shaped groove for the sliding rod 19 to slide. The T-shaped groove is arranged in an L-shape along the direction in which the two clamping blocks 10 are opposite to each other. The L-shaped arrangement of the T-shaped groove on the clamping block 10 allows the connecting rod 18 to rotate to a state where the cantilever 4 is parallel or perpendicular. In this embodiment, the sliding rod 19 is slidably disposed in the T-shaped groove of the clamping block 10. When hoisting the strip plate, if the initial hoisting state of the strip plate is horizontal, then the strip plate is placed horizontally, and the retaining ring 17 on each clamping block 10 is moved to a vertically upward state. If the strip is initially vertical, then adjust the retaining ring 17 connected to the branch rope 8 of the first pull rope 7 to a vertical state, and adjust the retaining ring 17 connected to the branch rope 8 of the second pull rope 9 to a horizontal state. This makes the force on the connecting rod 18 more reasonable, less prone to deformation during long-term use, and also ensures the stability of the strip when it is suspended.

[0026] Furthermore, each connecting rod 18 is threadedly connected to a corresponding slide rod 19. The connecting rod 18 and slide rod 19 are detachable, facilitating the replacement of the connecting rod 18 or the retaining ring 17.

[0027] Furthermore, both the cantilever 4 and the support column 3 are telescopic rods. Specifically, the structure of the telescopic rod can be selected from existing technologies, preferably an electric telescopic rod. The raising or retracting of the support column 3 serves to adjust the hoisting height of the device, and the extension or shortening of the cantilever 4 serves to adjust the hoisting distance of the device.

[0028] 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.
