Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a material transfer device for building labor construction. Background Technology

[0002] Existing construction material transport vehicles are prone to material falling off during use, affecting material transport.

[0003] Compared to patent publication number CN211943407U, a material transfer vehicle for construction uses a different method. In this method, the operator places the material to be transferred on the vehicle body, then adjusts the position of the clamps using a telescopic rod to fix the two clamps on both sides of the material, thus securing it. Next, the position of the locking blocks is adjusted by sliding them along a groove, fixing the two blocks to both ends of the material. Finally, a bolt is rotated clockwise on the connecting block until it enters the threaded hole, limiting the locking blocks and preventing them from sliding, thus increasing the effectiveness of securing the material.

[0004] The aforementioned construction material transfer vehicle requires adjusting the positions of two clamping plates and then limiting the two locking blocks when securing materials. This operation is cumbersome and reduces the efficiency of securing materials. Furthermore, relying on manual operation to bring the two locking blocks close to the materials for clamping cannot guarantee the clamping force. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a material transfer device for construction labor. Through a linkage adjustment structure composed of a crank handle, a bidirectional threaded rod, a threaded sleeve, and a U-shaped slide, only rotating the crank handle is needed to drive two sets of clamping components to move closer or separate synchronously, eliminating the need for separate adjustment of each set of clamping components. This significantly shortens the preparation time before material clamping and greatly improves operational efficiency. Simultaneously, the rotational precision of the bidirectional threaded rod allows for accurate control of the movement distance of the clamping components, thereby flexibly adjusting the clamping degree on the material. This ensures that the material remains stable and does not shake during transfer, while also preventing damage to the material due to excessive clamping force.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material transfer device for construction labor, comprising a platform;

[0007] The clamping assembly is provided on the upper surface of the vehicle board. There are two sets of clamping assemblies, which are symmetrically distributed on the upper surface of the vehicle board. Each clamping assembly includes an arc-shaped clamping plate. A U-shaped clamping plate is fixedly connected to the outer arc surface of the arc-shaped clamping plate. A connecting sleeve is provided on the bottom surface of the arc-shaped clamping plate. A supporting slide is fixedly connected to the bottom end of the connecting sleeve.

[0008] An adjustment assembly is provided at the bottom of the vehicle platform. The adjustment assembly is used to adjust the distance between the two sets of clamping assemblies. The adjustment assembly includes a bidirectional threaded rod. A threaded sleeve is threaded onto the outer wall of the bidirectional threaded rod. A C-shaped slide is fixedly connected to the outer wall of the threaded sleeve. The top of the C-shaped slide is fixedly connected to the bottom surface of the supporting slide plate.

[0009] A transverse sliding groove is formed on the upper surface of the vehicle body.

[0010] In a preferred embodiment of this utility model, the outer wall of the C-shaped slide near the top is slidably connected to the inner wall of the transverse sliding groove. The connecting sleeve includes an inner sleeve and an outer sleeve. The top end of the inner sleeve is fixedly connected to the bottom surface of the supporting slide plate, and the bottom end of the outer sleeve is fixedly connected to the upper surface of the supporting slide plate. The inner sleeve is movably inserted into the outer sleeve.

[0011] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the side of the arc-shaped clamping plate near the bottom end, an adjusting bolt is movably passed through the bottom surface of the connecting plate, and an installation hole adapted to the adjusting bolt is provided on the upper surface of the supporting slide plate.

[0012] In a preferred embodiment of this invention, a limiting washer is movably fitted onto the outer wall of the adjusting bolt near its top end, and a fixing nut is movably connected to the bottom surface of the limiting washer. The fixing nut is threaded onto the outer wall of the adjusting bolt, and the bottom end of the adjusting bolt is threadedly connected to the inner wall of the mounting hole.

[0013] In a preferred embodiment of this invention, the outer wall of the U-shaped carriage near the top is slidably connected to the inner wall of the transverse sliding groove, and both ends of the bidirectional threaded rod are rotatably connected to the bottom surface of the vehicle plate through a bearing seat.

[0014] As a preferred embodiment of this utility model, one end of the bidirectional threaded rod is fixedly connected to a crank handle, the bottom surface of the vehicle plate is fixedly connected to a movable wheel, and the upper surface of the vehicle plate near one end is fixedly connected to a push handle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model utilizes a linkage adjustment structure comprised of a crank handle, a bidirectional threaded rod, a threaded sleeve, and a U-shaped slide frame. Simply rotating the crank handle drives the two sets of clamping components to move closer or further apart synchronously, eliminating the need for separate adjustment of each set. This significantly reduces preparation time before material clamping and greatly improves operational efficiency. Simultaneously, the rotational precision of the bidirectional threaded rod allows for accurate control of the clamping component's movement distance, thereby flexibly adjusting the clamping force on the material. This ensures the material remains stable and does not wobble during transport, while also preventing damage due to excessive clamping force.

[0017] 2. This utility model integrates two clamping structures—a C-shaped clamping plate and an arc-shaped clamping plate—through a clamping assembly. The detachable connection between the adjusting bolt and the mounting hole, combined with the rotation function of the connecting sleeve, allows for quick switching between the two clamping plates. The C-shaped clamping plate is suitable for clamping materials with regular cross-sections such as rectangles and squares, while the arc-shaped clamping plate is suitable for curved materials such as circles and arcs, significantly expanding the device's adaptability to materials of different shapes. Furthermore, by utilizing the lifting and lowering adjustment of the adjusting bolt within the mounting hole and the telescopic characteristics of the connecting sleeve, the height of the arc-shaped clamping plate can be flexibly adjusted, further adapting to the clamping needs of materials of different heights and improving the device's practicality in complex construction scenarios.

[0018] 3. This utility model utilizes a sliding fit structure between a U-shaped slide and a transverse sliding groove to precisely guide and limit the movement of the clamping component, preventing deviation and wobbling during movement and ensuring accurate clamping and positioning of the material. Simultaneously, the connection between the adjusting bolt, limiting washer, and fixing nut ensures stable fixation of the clamping plate. Combined with the telescopic limiting function of the connecting sleeve, this effectively prevents the clamping plate from loosening or shifting during material transfer, reducing the risk of material falling and improving the safety of the transfer operation.

[0028] Example 1

[0029] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a material transfer device for construction labor, including a vehicle platform 1;

[0030] The clamping assembly 5 is provided on the upper surface of the vehicle plate 1. There are two sets of clamping assemblies 5, which are symmetrically distributed on the upper surface of the vehicle plate 1. The clamping assembly 5 includes an arc-shaped clamping plate 8. A U-shaped clamping plate 7 is fixedly connected to the outer arc surface of the arc-shaped clamping plate 8. A connecting sleeve 9 is provided on the bottom surface of the arc-shaped clamping plate 8. A supporting slide plate 10 is fixedly connected to the bottom end of the connecting sleeve 9.

[0031] An adjustment component is provided at the bottom of the vehicle plate 1. The adjustment component is used to adjust the distance between the two sets of clamping components 5. The adjustment component includes a bidirectional threaded rod 6. A threaded sleeve 12 is threadedly sleeved on the outer wall of the bidirectional threaded rod 6. A U-shaped slide 11 is fixedly connected to the outer wall of the threaded sleeve 12. The top of the U-shaped slide 11 is fixedly connected to the bottom surface of the support slide plate 10.

[0032] A transverse sliding groove 4 is formed on the upper surface of the car body 1.

[0033] Specifically, through the linkage adjustment structure consisting of the crank handle 17, the bidirectional threaded rod 6, the threaded sleeve 12, and the U-shaped slide 11, only rotating the crank handle 17 is needed to drive the two sets of clamping components 5 to move closer or separate synchronously. This eliminates the need for separate adjustment of the two sets of clamping components 5, significantly shortening the preparation time before material clamping and greatly improving operational efficiency. Simultaneously, the rotational precision of the bidirectional threaded rod 6 allows for precise control of the movement distance of the clamping components 5, thereby flexibly adjusting the clamping degree on the material. This ensures that the material remains stable and does not shake during transport, while also preventing damage to the material due to excessive clamping force.

[0034] Example 2

[0035] The second embodiment of this utility model provides a technical solution: the outer wall of the C-shaped slide 11 near the top is slidably connected to the inner wall of the transverse sliding groove 4, the connecting sleeve 9 includes an inner tube and an outer tube, the top of the inner tube is fixedly connected to the bottom surface of the supporting slide plate 10, the bottom of the outer tube is fixedly connected to the upper surface of the supporting slide plate 10, and the inner tube is movably inserted into the outer tube.

[0036] A connecting plate is fixedly connected to one side of the arc-shaped clamping plate 8 near the bottom. An adjusting bolt 13 is movably passed through the bottom surface of the connecting plate. An installation hole 16 adapted to the adjusting bolt 13 is opened on the upper surface of the supporting slide plate 10.

[0037] A limiting washer 14 is movably sleeved on the outer wall near the top of the adjusting bolt 13. A fixing nut 15 is movably connected to the bottom surface of the limiting washer 14. The fixing nut 15 is threaded onto the outer wall of the adjusting bolt 13. The bottom end of the adjusting bolt 13 is threadedly connected to the inner wall of the mounting hole 16.

[0038] Specifically, the clamping assembly 5 integrates two clamping structures: a U-shaped clamping plate 7 and an arc-shaped clamping plate 8. The detachable connection between the adjusting bolt 13 and the mounting hole 16, combined with the rotation function of the connecting sleeve 9, allows for quick switching between the two clamping plates. The U-shaped clamping plate 7 is suitable for clamping materials with regular cross-sections such as rectangles and squares, while the arc-shaped clamping plate 8 is suitable for curved materials such as circles and arcs, significantly expanding the device's adaptability to materials of different shapes. Furthermore, by utilizing the lifting adjustment of the adjusting bolt 13 within the mounting hole 16 and the telescopic characteristics of the connecting sleeve 9, the height of the arc-shaped clamping plate 8 can be flexibly adjusted, further adapting to the clamping needs of materials of different heights and improving the device's practicality in complex construction scenarios.

[0039] Example 3

[0040] The third embodiment of this utility model provides a technical solution: the outer wall of the U-shaped slide 11 near the top is slidably connected to the inner wall of the transverse sliding groove 4, and both ends of the bidirectional threaded rod 6 are rotatably connected to the bottom surface of the carriage 1 through a bearing seat. A crank handle 17 is fixedly connected to one end of the bidirectional threaded rod 6, a moving wheel 2 is fixedly connected to the bottom surface of the carriage 1, and a push handle 3 is fixedly connected to the upper surface of the carriage 1 near one end.

[0041] Example 4

[0042] The fourth embodiment of this utility model provides a technical solution: the inner wall of the outer sleeve of the connecting sleeve 9 is provided with 2 to 3 evenly distributed guide grooves along the axial direction, and the corresponding position of the outer wall of the inner sleeve is provided with guide protrusions that are adapted to the guide grooves. The guide protrusions are slidably embedded in the guide grooves to realize the axial guidance of the inner sleeve and the outer sleeve and prevent relative rotation.

[0043] Working principle:

[0044] When materials need to be clamped and fixed, the operator rotates the crank handle 17, which drives the bidirectional threaded rod 6 to rotate around its two end bearings. Since the outer wall of the bidirectional threaded rod 6 is threaded with threaded sleeves 12, and the threads of the bidirectional threaded rod 6 are bidirectionally symmetrically distributed, under its rotation, the two sets of threaded sleeves 12 synchronously translate along the axis of the bidirectional threaded rod 6 towards the center of the vehicle plate 1. The C-shaped slide 11, fixedly connected to the outer wall of the threaded sleeve 12, moves synchronously with the threaded sleeve 12. Because the outer wall of the C-shaped slide 11 near the top is slidably connected to the inner wall of the transverse sliding groove 4 opened on the upper surface of the vehicle plate 1, the transverse sliding groove 4 limits the direction of movement of the C-shaped slide 11, ensuring its stable translation. The top of the U-shaped slide 11 is fixedly connected to the bottom surface of the support slide 10, thereby driving the clamping components 5 on the support slide 10 to move synchronously. The two sets of clamping components 5 approach each other and contact the material. By continuously rotating the crank handle 17, the pressure between the clamping components 5 and the material can be adjusted until the required clamping degree is reached, thus completing the clamping and fixing of the material.

[0045] When the arc-shaped clamping plate 8 is needed to clamp materials, the operator rotates the adjusting bolt 13, causing the adjusting bolt 13 to rotate upwards from the inner wall of the mounting hole 16 on the upper surface of the support slide plate 10 and disengage from the mounting hole 16. At this time, the arc-shaped clamping plate 8 can rotate around the support slide plate 10 through the connecting sleeve 9. After rotating the arc-shaped clamping plate 8 half a turn, the adjusting bolt 13 is reconnected to the corresponding mounting hole 16 and tightened. The limiting washer 14, which is movably sleeved on the outer wall of the adjusting bolt 13, cooperates with the fixing nut 15 to enhance the stability of the connection, thereby realizing the adaptive clamping of materials by the arc-shaped clamping plate 8. When it is necessary to adjust the height of the arc-shaped clamping plate 8, the adjusting bolt 13 is rotated upward on the inner wall of the mounting hole 16 without disengaging from the mounting hole 16. At this time, the arc-shaped clamping plate 8 moves upward under the pushing action of the limiting washer 14 and the fixing nut 15. The inner tube of the connecting sleeve 9 extends and retracts along the axial direction of the outer sleeve (the top of the inner tube is fixedly connected to the bottom surface of the support slide plate 10, the bottom of the outer sleeve is fixedly connected to the upper surface of the support slide plate 10, and the inner tube is movably inserted into the outer sleeve), thereby realizing the fine adjustment of the height of the arc-shaped clamping plate 8 to adapt to the clamping requirements of materials of different sizes.

[0046] After the material is clamped and fixed, the operator pushes the cart 1 with the push handle 3 and uses the moving wheels 2 to transfer the material to the target position. After reaching the destination, the crank handle 17 is rotated in the opposite direction, which drives the bidirectional threaded rod 6 to rotate in the opposite direction, so that the two sets of threaded sleeves 12 move away from the center of the cart 1 along the bidirectional threaded rod 6. Then, through the C-shaped slide 11, the clamping assembly 5 is separated from each other, releasing the clamping of the material and completing the unloading of the material.

[0047] In summary, the linkage adjustment structure consisting of the crank handle 17, the bidirectional threaded rod 6, the threaded sleeve 12, and the U-shaped slide 11 allows for the simultaneous approach or separation of the two clamping components 5 simply by rotating the crank handle 17. This eliminates the need for separate adjustment of each clamping component 5, significantly reducing preparation time before material clamping and greatly improving operational efficiency. Furthermore, the rotational precision of the bidirectional threaded rod 6 allows for accurate control of the movement distance of the clamping components 5, enabling flexible adjustment of the clamping force on the material. This ensures the material remains stable and does not wobble during transport, while also preventing damage due to excessive clamping force.
