Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a hoisting device for prefabricated building installation. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] Chinese invention patent CN116692716A discloses a hoisting device for prefabricated building construction, including a vehicle body, a base, a hoisting frame, a hoisting block, a hoisting mechanism, a fall protection mechanism, a first fixed seat, a second fixed seat, a first steel rope, and two vertical rods. The base is located at the top front end of the vehicle body, the hoisting frame is mounted on top of the base, and the top of the hoisting block is provided with a hoisting ring. The first fixed seat is installed at the top rear end of the vehicle body, and the second fixed seat is installed on top of the hoisting frame. The tail end of the first steel rope is fixed to a take-up roller, and the head end of the first steel rope passes through a pulley and connects to the hoisting ring. The hoisting mechanism is installed on the outer wall of the hoisting block, and the fall protection mechanism is installed at the bottom end of the hoisting frame. The hoisting mechanism of this invention can adjust its vertical length to match prefabricated building panels of different sizes, making it widely applicable. The fall protection mechanism provides buffer and fall protection for the hoisting block, preventing the prefabricated building panels from falling and injuring personnel, thus ensuring high safety.

[0004] However, in actual use, the aforementioned patent still has the problem that the counterweight needs to be manually adjusted and cannot be dynamically adjusted according to the hoisting load, which poses a stability risk. Utility Model Content

[0005] The purpose of this utility model is to provide a hoisting device for prefabricated building installation that uses a hydraulic pump station linked with a winding mechanism to adjust the position of the counterweight frame when the winding mechanism is working, so that the moving direction of the counterweight frame and the lifting direction of the hoisting steel cable form a torque balance relationship, thereby realizing the dynamic balance of the counterweight block. This solves the problems mentioned in the background art.

[0006] To achieve the above objectives, a hoisting device for prefabricated building installation is provided, comprising a vehicle body, a base, a hoisting frame, a hoisting mechanism, a fall protection mechanism, a first fixed seat, a second fixed seat, a counterweight frame, a counterweight block, a first steel rope, a vertical rod, and a winding mechanism located at the top of the first fixed seat. A hydraulic pump station is provided at the top of the vehicle body, and the input end of the hydraulic pump station is coaxial with the winding mechanism. A hydraulic telescopic rod is provided at the top of the vehicle body, which is connected to the hydraulic pump station via a hydraulic pipe, and the output end of the hydraulic telescopic rod is hinged to the counterweight block. A slide rail is provided at the top of the vehicle body that slides in cooperation with the counterweight frame.

[0007] Furthermore, the winding mechanism includes a winding roller fixed to the top of the first fixed base, a winding motor is provided on one side of the winding roller, the output end of the winding motor is fixedly connected to the winding roller shaft through a pin, and further, the shaft extends to the input end of the hydraulic pump station and is linked through a coupling.

[0008] Furthermore, the hydraulic telescopic rod is positioned between the take-up roller and the first fixed seat, and the axis of the hydraulic telescopic rod is perpendicular to the axis of the take-up roller.

[0009] Furthermore, the slide rail includes a long strip track with a downward-extending roller groove at the top of the track, and multiple rollers spaced apart along the length direction inside the roller groove.

[0010] Furthermore, the hoisting frame is a portal frame with an opening to the left, including a hoisting plate, upper and lower mounting plates, and two auxiliary beams. Multiple reinforcing rods are provided between the auxiliary beams and the hoisting plate, and the angle between the reinforcing rods and the auxiliary beams is 30-60°.

[0011] This utility model has the following advantages over the prior art: This invention achieves real-time balance of lifting torque through the mechanical linkage between the hydraulic pump station and the winding mechanism, solving the problems of insufficient stability and low efficiency of manual adjustment caused by the reliance on static counterweights in traditional equipment. It effectively improves lifting stability, reduces the risk of overturning, reduces manual operation, and improves work efficiency. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] In one implementation, please refer to Figure 1 As shown, a hoisting device for prefabricated building installation includes a vehicle body 1, a base 11, a hoisting frame 2, a hoisting mechanism 3, a fall protection mechanism 4, a first fixed seat 5, a second fixed seat 6, a counterweight frame 12, a counterweight block 13, a first steel rope 7, a vertical rod 8, and a winding mechanism located at the top of the first fixed seat 5. The top of the vehicle body 1 is equipped with a hydraulic pump station 14, the input end of which is coaxial with the winding mechanism. The top of the vehicle body 1 is equipped with a hydraulic telescopic rod 15 connected to the hydraulic pump station 14 via a hydraulic pipe, the output end of which is hinged to the counterweight block 13. The top of the vehicle body 1 is equipped with a slide rail 10 that slides with the counterweight frame 12.

[0016] Understandable, Figure 1 The images shown are merely illustrative examples of some components of hoisting equipment used for prefabricated building installation; the actual shape, size, and construction of these components are not subject to change. Figure 1 Furthermore, the structural details of components such as the hoisting mechanism 3 and the fall arrest mechanism 4 have already been disclosed in CN116692716A.

[0017] In addition, please see the appendix. Figure 1 and attached Figure 4 The first fixed seat 5 is screwed to the top of the vehicle body 1. The winding mechanism includes a winding roller that rotates with the first fixed seat 5. A winding motor 9 is provided on one side of the winding roller. The output end of the winding motor 9 is fixedly connected to the rotating shaft of the winding roller through a pin. The rotating shaft of the winding roller passes through the winding roller and extends along the axis to the input end of the hydraulic pump station 14. The input end of the hydraulic pump station 14 is fixedly connected to the rotating shaft through a coupling, thereby realizing the control of the hydraulic telescopic rod 15 by the hydraulic pump station 14 following the rotation direction of the winding roller.

[0018] Specifically, please refer to the appendix. Figure 4 The hydraulic telescopic rod 15 is disposed between the take-up roller and the first fixed seat 5, and the axis of the hydraulic telescopic rod 15 is perpendicular to the axis of the take-up roller.

[0019] Additionally, please see the appendix. Figure 5 The slide rail 10 includes a long, narrow track 101, with a roller groove 103 extending downward from the top of the track 101. A plurality of rollers 102 are arranged at intervals along the length of the roller groove 103 within the roller groove 103. In this application, "a plurality of" means at least two.

[0020] In this embodiment, the components such as the vehicle body 1, base 11, lifting frame 2, lifting mechanism 3, anti-fall mechanism 4, first fixed seat 5, second fixed seat 6, counterweight frame 12, counterweight block 13, first steel rope 7, vertical rod 8, and winding mechanism located at the top of the first fixed seat 5 have been disclosed in CN116692716A. During the lifting operation, the object to be lifted is fixed by the lifting mechanism 3, and then the winding motor 9 is started and drives the winding roller to work, thereby realizing the lifting mechanism 3 moving up and down along the vertical rod 8. At the same time, the rotating shaft synchronously drives the input shaft of the hydraulic pump station 14 to rotate. The hydraulic pump station 14 adjusts the flow direction of hydraulic oil according to the rotation direction of the rotating shaft, thereby controlling the extension and retraction of the hydraulic telescopic rod 15, thereby realizing the connection control between the lifting height and the counterweight position. When the winding roller rotates clockwise to wind up the first steel rope 7, the hydraulic pump station 14 drives the hydraulic telescopic rod 15 to extend, pushing the counterweight block 13 to move along the slide rail 10 toward the rear end of the vehicle body 1 to balance the overturning moment generated by the hoisting load; conversely, when the winding roller releases the rope counterclockwise, the hydraulic telescopic rod 15 retracts, and the counterweight block 13 moves forward to reduce the counterweight moment. Meanwhile, since multiple rollers 102 are arranged in the roller groove 103 of the track 101, the sliding friction between the counterweight frame 12 and the slide rail 10 is changed to rolling friction, which reduces the thrust required to push the counterweight frame 12 and reduces energy consumption.

[0021] In another embodiment, please refer to the appendix. Figure 4 The hoisting frame 2 includes a portal frame, which comprises a plate-shaped hoisting plate. A lower mounting plate and an upper mounting plate extend to the left from both the upper and lower ends of the hoisting plate. The portal frame opening faces left. Two auxiliary beams 201 are provided between the opposite faces of the upper and lower mounting plates, away from the hoisting plate. Multiple reinforcing rods 202 are provided between the auxiliary beams 201 and the opposite faces of the hoisting plate. The angle between the reinforcing rods 202 and the auxiliary beams 201 is 30-60 degrees; preferably, the angle between the reinforcing rods 202 and the auxiliary beams 201 is 45 degrees. In this application, "multiple" means at least two.

[0022] In this embodiment, by adding an auxiliary beam 201 to the upper / lower mounting plate bracket, the bending resistance of the hoisting frame 2 is improved. Then, by adding a reinforcing rod 202 between the auxiliary beam 201 and the hoisting plate, with the angle between the reinforcing rod 202 and the auxiliary beam 201 being 45°, a stable triangular support structure is formed, which further improves the torsional resistance.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
