Description

Technical Field

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

[0002] With the acceleration of industrialization in the construction industry, prefabricated buildings have been widely used in various construction projects due to their advantages such as short construction cycles and controllable component quality. The core of prefabricated buildings lies in the use of a large number of standardized prefabricated components. These prefabricated components (such as wall panels and composite slabs) are usually large in size and heavy in weight, and the transfer between the production site and the construction site is highly dependent on specialized transfer equipment.

[0003] Currently, there are various devices available in the industry for transporting precast components. For example, Chinese utility model patent CN223213700U discloses a device for unloading and hoisting precast concrete components at a water conservancy construction site. This device, through the cooperation of a ring plate, an L-shaped support plate, a moving mechanism, and an electric hoist, achieves horizontal movement and lifting unloading of precast components, thus meeting the basic transportation needs to a certain extent.

[0004] However, the existing equipment mentioned above still has obvious shortcomings in practical applications: First, it does not have a swing amplitude limiting mechanism designed for the hoisting process of prefabricated components. After the electric hoist lifts the prefabricated component, it is very easy for it to sway left and right or back and forth when moving horizontally or affected by external airflow and inertia. Second, such swaying not only leads to unstable posture of the prefabricated component, increasing the risk of collision damage, but may also cause safety accidents due to excessive swaying amplitude. It is difficult to meet the high precision and high safety requirements of transporting prefabricated components for prefabricated buildings. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a prefabricated building component transfer device that has the advantage of limiting the swing amplitude, thus solving the problem that the lack of a swing amplitude limiting mechanism in existing equipment leads to large swings of prefabricated components during the transfer process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building component transfer device, comprising a transfer mechanism, the transfer mechanism including a movable frame, universal wheels fixedly installed at the four corners of the bottom of the movable frame, an I-beam fixedly installed at the top of the movable frame, an electric hoist slidably installed at the bottom of the surface of the I-beam, the rope end of the electric hoist connected to the transfer frame, and a swing amplitude limiting mechanism, the swing amplitude limiting mechanism including a nylon cloth belt, the nylon cloth belt being disposed on the left and right sides of the bottom of the transfer frame, a fixing rod fixedly installed on the left and right sides of the inner side of the movable frame, a fixing frame fixedly installed at the top of the fixing rod, an upper clamping plate fixedly installed at the top of the inner side of the fixing frame, a lower clamping plate disposed at the bottom of the inner side of the fixing frame, a transmission assembly movably connected to the bottom of the inner side of the lower clamping plate via a bearing, an engagement assembly fixedly connected to the top of the lower clamping plate, and mounting assemblies provided on the front and rear sides of the nylon cloth belt near the bottom of the transfer frame.

[0007] In a preferred embodiment of this invention, the transmission assembly includes a screw, which is movably connected to the bottom of the lower clamping plate via a bearing. The fixed rod has a transmission screw hole inside that is used to engage with the screw, and the screw is threaded into the transmission screw hole.

[0008] As a preferred embodiment of the present invention, the biting component includes tooth blocks, which are fixedly connected to the top of the lower clamping plate. Multiple tooth blocks are provided and are evenly distributed. The bottom of the upper clamping plate is provided with tooth grooves for use with the tooth blocks.

[0009] As a preferred embodiment of this utility model, the mounting component includes mounting holes, which are opened on the front and rear sides of the bottom of the nylon tape near the transfer frame. Bolts are installed inside the mounting holes, and fixing screw holes for use with the bolts are opened at the four corners of the bottom of the transfer frame. The bolts pass through the mounting holes and are threadedly connected to the fixing screw holes.

[0010] As a preferred embodiment of this utility model, guide rods are fixedly connected to the front and rear sides of the bottom of the lower clamping plate, and guide holes for use with the guide rods are opened inside the fixed rods.

[0011] As a preferred embodiment of this invention, a metal ring is fixedly fitted inside the mounting hole.

[0012] As a preferred embodiment of this invention, a drive handwheel is fixedly connected to the bottom end of the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a swing amplitude limiting mechanism, has nylon cloth straps installed on both sides of the bottom of the transfer frame through an installation assembly. After being lifted, the nylon cloth straps pass between the upper and lower clamping plates, and the lower clamping plate is driven to move towards the upper clamping plate through a transmission assembly. The upper and lower clamping plates clamp and fix the nylon cloth straps through an interlocking assembly. When the precast component is lifted and transferred, the nylon cloth straps can limit the range of motion of the transfer frame and the precast component, preventing it from swinging significantly due to inertia, airflow, and other factors. This solves the problem of significant swinging of precast components during the transfer process caused by the lack of a swing amplitude limiting mechanism in existing equipment, and achieves the effect of limiting the swing amplitude.

[0015] 2. This utility model, by setting up a transmission component, can precisely control the lifting distance of the lower clamping plate through the threaded engagement of the screw and the transmission screw hole. This avoids the nylon tape from slipping due to excessively loose clamping or being damaged by excessively tight clamping. The threaded transmission has a natural self-locking characteristic. After the screw and the transmission screw hole are engaged, the lower clamping plate will not move on its own due to the tension of the nylon tape or the weight of the prefabricated parts if there is no active rotation of the screw, ensuring that the clamping force on the nylon tape remains stable during the transfer process.

[0016] 3. By setting up an interlocking component, the meshing of the toothed blocks and toothed grooves can significantly increase the friction of the clamping plate on the nylon tape. Compared with a smooth clamping plate, it can effectively prevent the nylon tape from sliding under force. Multiple equally spaced toothed blocks can evenly distribute the clamping force on the surface of the nylon tape, avoiding excessive local pressure that could cause damage to the nylon tape, extending the service life of the nylon tape, reducing equipment maintenance costs, and ensuring the reliability of clamping, thus avoiding safety hazards caused by damage to the nylon tape.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the appendix to the specification. Figure 1-3 The specific embodiments of this utility model are described in detail.

[0022] Example 1

[0023] Reference Figure 1-3 This is the first embodiment of the present invention, providing a prefabricated building component transfer device, including a transfer mechanism 1. The transfer mechanism 1 includes a movable frame 101, with casters 102 fixedly installed at the four corners of the bottom of the movable frame 101, an I-beam 103 fixedly installed on the top of the movable frame 101, an electric hoist 104 slidably installed on the bottom of the surface of the I-beam 103, and a transfer frame 105 connected to the rope end of the electric hoist 104. Also included is a swing amplitude limiting mechanism 2, which includes a nylon strap 21. The nylon strap 21 is set... Fixed rods 22 are fixedly installed on the left and right sides of the bottom of the transfer frame 105 and on the left and right sides of the inner side of the movable frame 101. Fixed frame 23 is fixedly installed on the top of the fixed rods 22. Upper clamping plate 24 is fixedly installed on the top inside the fixed frame 23. Lower clamping plate 25 is provided at the bottom inside the fixed frame 23. Transmission assembly 26 is movably connected to the bottom inside the lower clamping plate 25 through bearings. Engaging assembly 27 is fixedly connected to the top of the lower clamping plate 25. Mounting assembly 28 is provided on the front and rear sides of the bottom of the nylon cloth belt 21 near the bottom of the transfer frame 105.

[0024] Specifically, by setting up a swing amplitude limiting mechanism 2 consisting of a nylon cloth belt 21, a fixing frame 23, an upper clamping plate 24, and a lower clamping plate 25, the swing range during the transfer of precast components can be effectively limited, avoiding left-right and front-back swaying caused by inertia and airflow interference, thus achieving stable suspension and transfer of precast components.

[0025] Furthermore, nylon straps 21 are provided on the left and right sides of the bottom of the transfer frame 105. The end of the strap near the transfer frame 105 is fixed to the transfer frame 105 by the mounting assembly 28. Fixing frames 23 are fixed on the fixing rods 22 on the left and right sides inside the movable frame 101. The upper clamping plate 24 and the adjustable lower clamping plate 25 inside the fixing frame 23 cooperate to clamp and fix the nylon straps 21. When the prefabricated part is lifted and transferred, the nylon straps 21 can limit the range of motion of the transfer frame 105 and the prefabricated part, preventing them from swinging significantly due to inertia, airflow and other factors. If the transfer position needs to be adjusted, the clamping of the nylon straps 21 by the lower clamping plate 25 can be loosened first. After the electric hoist 104 moves the transfer frame 105 to a suitable position, the nylon straps 21 are clamped again by the cooperation of the lower clamping plate 25 and the upper clamping plate 24 to ensure the stability of the subsequent transfer process.

[0026] Example 2

[0027] In the second embodiment of this utility model, the transmission assembly 26 includes a screw 261, which is movably connected to the bottom of the lower clamping plate 25 via a bearing. The fixed rod 22 has a transmission screw hole 262 that is used to cooperate with the screw 261, and the screw 261 is threadedly connected to the inside of the transmission screw hole 262.

[0028] Specifically, by setting up the transmission component 26, the lifting distance of the lower clamping plate 25 can be precisely controlled through the threaded engagement of the screw 261 and the transmission screw hole 262. This prevents the nylon tape 21 from slipping due to excessively loose clamping or from being damaged by excessively tight clamping. The threaded transmission has a natural self-locking characteristic. After the screw 261 engages with the transmission screw hole 262, the lower clamping plate 25 will not move on its own due to the tension of the nylon tape 21 or the weight of the prefabricated part if the screw 261 is not actively rotated. This ensures that the clamping force on the nylon tape 21 remains stable during the transfer process.

[0029] Furthermore, when it is necessary to clamp or loosen the nylon tape 21, since the screw 261 is movably connected to the bottom of the lower clamping plate 25 through the bearing, and the screw 261 is threadedly connected to the transmission screw hole 262 inside the fixed rod 22, when the screw 261 is rotated, the screw 261 will move axially along the internal thread of the transmission screw hole 262, thereby driving the lower clamping plate 25 to move up and down synchronously: when the screw 261 is rotated clockwise, the screw 261 moves upward along the transmission screw hole 262, pushing the lower clamping plate 25 closer to the upper clamping plate 24, until the engagement component 27 at the top of the lower clamping plate 25 cooperates with the upper clamping plate 24 to clamp the nylon tape 21; when the screw 261 is rotated counterclockwise, the screw 261 moves downward along the transmission screw hole 262, driving the lower clamping plate 25 away from the upper clamping plate 24, releasing the clamping of the nylon tape 21. At this time, the electric hoist 104 can drive the transfer frame 105 and the prefabricated parts to move freely.

[0030] Example 3

[0031] In the third embodiment of this utility model, the biting component 27 includes tooth blocks 271, which are fixedly connected to the top of the lower clamping plate 25. Multiple tooth blocks 271 are provided and are distributed at equal distances. The bottom of the upper clamping plate 24 is provided with tooth grooves 272 that cooperate with the tooth blocks 271.

[0032] Specifically, by setting the biting component 27, the meshing of the toothed block 271 and the toothed groove 272 can significantly increase the friction of the clamping plate on the nylon tape 21. Compared with a smooth clamping plate, it can effectively prevent the nylon tape 21 from sliding when under force. Multiple equally spaced toothed blocks 271 can evenly distribute the clamping force on the surface of the nylon tape 21, avoiding excessive local pressure that could cause the nylon tape 21 to break, extending the service life of the nylon tape 21, reducing equipment maintenance costs, and ensuring the reliability of clamping, thus avoiding safety hazards caused by damage to the nylon tape 21.

[0033] Furthermore, when the lower clamping plate 25 moves upward under the drive of the transmission assembly 26, the multiple equally spaced toothed blocks 271 fixed at the top of the lower clamping plate 25 gradually embed into the toothed grooves 272 opened at the bottom of the upper clamping plate 24, and the nylon tape 21 is clamped between the upper clamping plate 24 and the lower clamping plate 25. The meshing structure of the toothed blocks 271 and the toothed grooves 272 can increase the contact friction between the clamping plate and the nylon tape 21, while restricting the sliding of the nylon tape 21 in the horizontal direction. Even if the preform generates slight tension during the transfer process, the nylon tape 21 will not slide along the surface of the clamping plate, ensuring a stable swing restriction effect.

[0034] Example 4

[0035] In the fourth embodiment of this utility model, the mounting component 28 includes mounting holes 281. The mounting holes 281 are opened on the front and rear sides of the bottom of the nylon cloth belt 21 near the end of the transfer frame 105. Bolts 282 are provided inside the mounting holes 281. Fixing screw holes 283 for use with the bolts 282 are opened at the four corners of the bottom of the transfer frame 105. The bolts 282 pass through the mounting holes 281 and are threadedly connected to the fixing screw holes 283.

[0036] Specifically, by setting up the installation component 28 and connecting it with bolts 282, the nylon tape 21 is designed to be detachable. When the nylon tape 21 is worn, aged or damaged due to long-term stress, a new tape can be quickly replaced, which greatly reduces equipment maintenance costs and downtime.

[0037] Furthermore, when assembling or replacing the nylon tape 21, align the mounting hole 281 at the bottom of the end of the nylon tape 21 closest to the transfer frame 105 with the fixing screw holes 283 at the four corners of the bottom of the transfer frame 105. Then, pass the bolt 282 through the mounting hole 281 and screw it into the fixing screw hole 283. Through the threaded connection between the bolt 282 and the fixing screw hole 283, the nylon tape 21 is tightly fixed to the transfer frame 105. If it is necessary to remove the nylon tape 21, simply unscrew the bolt 282 to remove the nylon tape 21 from the transfer frame 105. The operation is convenient and the connection is reliable.

[0038] Working principle:

[0039] Construction workers push the mobile frame 101, using the casters 102 mounted at its four corners to move the entire transfer device to the precast component storage location, ensuring the transfer frame 105 is directly above the precast component for initial positioning. Then, the electric hoist 104, slidably mounted on the surface of the I-beam 103, is activated. The hoist 104 releases its rope, slowly lowering the transfer frame 105 until it contacts the precast component or reaches a suitable height for fixing it. The precast component is then placed on top of the transfer frame 105, and the electric hoist 104 is controlled to raise the transfer frame 105 to a suitable height. Finally, the nylon strapping 21 is threaded through the upper clamping plate 2. Between the upper clamping plate 24 and the lower clamping plate 25, adjust the extension length of the nylon tape 21 according to the estimated lifting height of the precast component to ensure that the nylon tape 21 is taut and has adjustment margin after lifting. Then, rotate the drive handwheel 6 clockwise to drive the screw 261 to move upward along the transmission screw hole 262, pushing the lower clamping plate 25 to rise. During this process, the guide rods 3 on the front and rear sides of the bottom of the lower clamping plate 25 slide along the guide holes 4 inside the fixed rod 22 to ensure that the lower clamping plate 25 rises and falls horizontally until the toothed block 271 at the top of the lower clamping plate 25 is embedded in the toothed groove 272 at the bottom of the upper clamping plate 24, and the nylon tape 21 is tightly clamped between the upper clamping plate 24 and the lower clamping plate 25. Between these steps, the swing limiting mechanism is fixed, and the electric hoist 104 is restarted. The electric hoist 104 retracts its rope, causing the transfer frame 105 and the fixed precast component to slowly rise. At this time, the nylon tape 21 is slightly taut, and the swing limiting mechanism begins to function. If short-distance lateral movement is required, the construction personnel push the moving frame 101 and adjust the overall position of the equipment using the casters 102. During this process, the precast component cannot swing significantly left, right, or back and forth due to the tension of the nylon tape 21. Because the upper clamping plate 24 and the lower clamping plate 25 clamp the nylon tape 21 through the meshing of the toothed block 271 and the toothed groove 272, the friction is increased. At the same time, the screw... The self-locking characteristics of the threads of 261 and the transmission screw hole 262 ensure the stability of the lower clamping plate 25 and prevent the nylon tape 21 from slipping. During the transfer process, the guide rod 3 and the guide hole 4 always ensure that the lower clamping plate 25 does not tilt. The metal ring 5 prevents the nylon tape 21 from being damaged by the compression of the bolt 282. All parts work together to ensure the stability of the precast part and eliminate the risk of collision. After the equipment is moved to the construction position, the drive handwheel 6 is rotated counterclockwise to loosen the lower clamping plate 25, remove the nylon tape 21, start the electric hoist 104 to release the rope, and drive the transfer frame 105 and the precast part to slowly descend until the precast part is placed stably on the installation position, completing the positioning and lowering.

[0040] In summary: By setting up the swing amplitude limiting mechanism 2, the nylon cloth strip 21 in the swing amplitude limiting mechanism 2 is installed on both sides of the bottom of the transfer frame 105 through the mounting assembly 28. After being lifted, the nylon cloth strip 21 passes between the upper clamping plate 24 and the lower clamping plate 25, and the lower clamping plate 25 is driven to move towards the upper clamping plate 24 through the transmission assembly 26. The upper clamping plate 24 and the lower clamping plate 25 clamp and fix the nylon cloth strip 21 through the biting assembly 27. When the precast part is lifted and transferred, the nylon cloth strip 21 can limit the range of motion of the transfer frame 105 and the precast part, and prevent it from swinging significantly due to inertia, airflow and other factors. This solves the problem of the precast part swinging significantly during the transfer process due to the lack of a swing amplitude limiting mechanism in the existing equipment, and achieves the effect of limiting the swing amplitude.
