Description

Technical Field

[0001] This utility model relates to the field of component hoisting technology, specifically to a prefabricated component hoisting device. Background Technology

[0002] Existing precast components are formed by filling steel bars into a template and pouring concrete. After molding, the precast component is demolded to obtain its complete shape. When transporting or installing large precast components, non-manual handling and docking are required, and hoisting equipment is needed. However, during hoisting, it is necessary to avoid severe shaking of the precast components, which can lead to problems such as hook detachment and chain breakage. Furthermore, it is difficult to carry out transportation and docking installation work during shaking. Therefore, a precast component hoisting device that solves the above problems is needed. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a prefabricated component hoisting device, which solves the problems mentioned in the background.

[0004] This utility model provides the following technical solution: a precast component hoisting device, comprising: a lifting node, a traction rope connected to the bottom of the lifting node, a lifting device connected to the bottom of the traction rope, a connecting seat provided on the outer wall of the lifting device, a rope movably connected to the bottom of the connecting seat, a hook connected to the bottom of the rope, a return spring connected to the inner wall of the hook, a dome column connected to the outer wall of the return spring, a lever connected to the outer wall of the dome column, a stepper motor mounted on the outer wall of the lifting device, a lead screw threadedly connected to the inner wall of the stepper motor, a mounting seat movably connected to the bottom of the lead screw, a sleeve fixedly connected to the mounting seat, a connector movably fitted onto the inner wall of the sleeve, a metal box connected to the bottom of the connector, a metal rod fitted onto the inner wall of the metal box, a connector mounted on the outer wall of the mounting seat, a balance spring connected to the outer wall of the connector, and a precast component provided at the bottom of the lifting device.

[0005] Preferably, the number of connecting seats is eight, and the eight connecting seats are arranged at the four corners of the lifting device and are symmetrical vertically.

[0006] Preferably, the number of traction ropes is four, and the four traction ropes are connected to the same lifting node and four connecting seats.

[0007] Preferably, the outer wall of the lead screw is provided with external threads, and the inner wall of the stepper motor meshes with the lead screw.

[0008] Preferably, the inner wall of the metal box has a through hole, and a metal nail is fitted into the hole.

[0009] Preferably, the end of the metal rod away from the metal box is arc-shaped, and the end of the metal rod away from the metal box passes through the inner cavity of the lifting ring.

[0010] Preferably, the two ends of the connector are respectively connected to the mounting base and the metal box, and the two ends of the balance spring are respectively connected to the connector.

[0011] Preferably, the outer wall of the precast component is connected with lifting rings, and the number of lifting rings is six.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This precast component hoisting device, through the setting of hooks, return springs, dome columns, levers, and lifting rings, allows the precast components on the device to be hoisted with the lifting equipment. The hook hooks the lifting ring, and at the same time, the lever is manually moved to compress the height of the return spring by the dome column in the inner cavity of the hook. This causes the hook to engage the lifting ring. When the hand is released, the return spring automatically pushes the dome column out, thereby closing the arc-shaped inner wall of the hook and preventing the hook from detaching when it hooks the lifting ring.

[0014] 2. This precast component hoisting device, through the installation of screw rods, metal boxes and connectors, balance springs, and metal rods, causes severe swaying of the precast components during hoisting. To prevent severe tilting of the precast components on both sides during this swaying, a metal rod is used to pass through the inner cavity of the lifting ring. When the screw rod pulls the metal box, the metal rod is pressed tightly against the lifting rings on both sides. This allows the balance springs connected by the connector to exert force on both sides simultaneously, keeping the precast components and the hoisting device in a balanced state. Consequently, a severe angular tilt occurs between the swaying precast components and the hoisting device, making it difficult to perform subsequent leveling or docking installation operations at the hoisting angle.

[0021] 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.

[0022] Please see Figure 1-5 The precast component hoisting device includes: a lifting node 1, a traction rope 2 connected to the bottom of the lifting node 1, a lifting device 3 connected to the bottom of the traction rope 2, a connecting seat 4 on the outer wall of the lifting device 3, a rope 5 movably connected to the bottom of the connecting seat 4, a hook 6 connected to the bottom of the rope 5, a return spring 7 connected to the inner wall of the hook 6, a dome column 8 connected to the outer wall of the return spring 7, a lever 9 connected to the outer wall of the dome column 8, a stepper motor 10 installed on the outer wall of the lifting device 3, a lead screw 11 threadedly connected to the inner wall of the stepper motor 10, a mounting seat 12 movably connected to the bottom of the lead screw 11, a sleeve 13 fixedly connected to the mounting seat 12, a socket joint 14 movably sleeved on the inner wall of the sleeve 13, a metal box 15 connected to the bottom of the socket joint 14, a metal rod 16 sleeved on the inner wall of the metal box 15, a connector 17 installed on the outer wall of the mounting seat 12, a balance spring 18 connected to the outer wall of the connector 17, and a precast component 19 at the bottom of the lifting device 3.

[0023] There are eight connecting seats 4, and the eight connecting seats 4 are arranged at the four corners of the lifting device 3 and are symmetrically arranged vertically. Through the eight connecting seats 4 on the device, the connecting seats 4 on the device are set at the four corner edges of the lifting device 3, and the upper and lower surfaces of the lifting device 3 are provided with connecting seats 4, so that the connecting seats 4 on the device are connected to the traction rope 2 and the rope 5 on the upper and lower sides of the lifting device 3 respectively.

[0024] There are four traction ropes 2, and the four traction ropes 2 are connected to the same lifting node 1 and four connecting seats 4. Through the four traction ropes 2 on the device, the lifting node 1 on the device is connected to the connecting seats 4 on the outer wall of the lifting device 3 by the four traction ropes 2, so that the lifting device 3 transfers the weight of the hoisting to the lifting node 1 through the traction ropes 2.

[0025] The lead screw 11 has an external thread on its outer wall, and the inner wall of the stepper motor 10 meshes with the lead screw 11. Because the lead screw 11 has an external thread on its outer wall, when the stepper motor 10 outputs rotational power, it drives the lead screw 11 to move up and down, so that the lead screw 11 carries the mounting base 12, metal box 15 and other structures to move up and down synchronously.

[0026] The inner wall of the metal box 15 has a through hole, and a metal nail is fitted into the hole. Because the inner wall of the metal box 15 has a through hole, the inner wall of the metal rod 16 on the device also has a through hole. The metal rod 16 is fixed with a metal nail before and after it extends and retracts in the inner cavity of the metal box 15, so that the metal rod 16 on the device can be fixed again before and after extension and retraction.

[0027] The end of the metal rod 16 away from the metal box 15 is set to be arc-shaped, and the end of the metal rod 16 away from the metal box 15 passes through the inner cavity of the lifting ring 20. By setting the end of the metal rod 16 away from the metal box 15 to be arc-shaped, the metal rod 16 on the device can extend and retract within the inner cavity of the metal box 15 after the height is reduced. By using the arc-shaped side of the metal rod 16 to pass through the inner cavity of the lifting ring 20, the metal rod 16 can be raised slightly and hook the lifting rings 20 on both sides of the precast part 19, thereby keeping the two sides of the precast part 19 at a parallel angle.

[0028] The connector 17 is connected to the mounting base 12 and the metal box 15 at both ends, and the balance spring 18 is connected to the connector 17 at both ends. By connecting the mounting base 12 and the metal box 15 at both ends of the connector 17, the connector 17 and the balance spring 18 form a triangular connection on both sides of the mounting base 12 and the metal box 15. When the metal rod 16 hooks the lifting ring 20, when the height of the two sides of the precast part 19 fluctuates, the balance spring 18 in the symmetrical state is compressed and stretched at the same time, so that the balance springs 18 on both sides exert force to bring the metal box 15 and the metal rod 16 to a balanced state, thus avoiding the inconsistency in the height of the two sides of the precast part 19.

[0029] The precast component 19 has six lifting rings 20 connected to its outer wall. By connecting the lifting rings 20 to the outer wall of the precast component 19, the precast component 19 can be lifted by hooking the hook 6 with four lifting rings 20 and by overlapping the metal rod 16 with two lifting rings 20. This allows the precast component 19 and the lifting device 3 to remain parallel, thus preventing the precast component 19 from swaying during lifting and causing uneven height on both sides, which could lead to disengagement.

[0030] The working principle is as follows: First, by setting up structures such as a hook 6, a return spring 7, a dome column 8, a lever 9, and a lifting ring 20, when the prefabricated component 19 on the device needs to be lifted with the lifting device 3, the hook 6 hooks the lifting ring 20, and at the same time, the lever 9 is manually moved to compress the height of the return spring 7 by pushing down the dome column 8 in the inner cavity of the hook 6, so that the hook 6 fits the lifting ring 20 in it. When the hand is released, the return spring 7 automatically pushes the dome column 8 out, thereby closing the arc-shaped inner wall of the hook 6 and preventing the hook 6 from disengaging when hooking the lifting ring 20. Then, by setting up structures such as a lead screw 11, a metal box 15 and a connector 17, a balance spring 18, and a metal rod 16, the device can be installed... When the precast component 19 is hooked and lifted by the hook 6, it will sway severely during the lifting process. In order to avoid the precast component 19 from tilting severely on both sides during the swaying process, a metal rod 16 is used to pass through the inner cavity of the lifting ring 20. When the lead screw 11 pulls the metal box 15, the metal rod 16 is close to the lifting rings 20 on both sides. This allows the swaying precast component 19 to be kept in a balanced state with the lifting device 3 by the balance spring 18 connected by the connector 17 exerting force on both sides. This causes the swaying precast component 19 to tilt severely at an angle with the lifting device 3, making it difficult to perform subsequent leveling or docking installation operations.

[0031] 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.
