Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a construction material transfer device for construction sites. Background Technology

[0002] On construction sites, the horizontal and sloping transfer of building materials is a key part of the entire construction process. Simple transfer equipment such as handcarts and wheelbarrows are widely used for short-distance transportation of bulk materials or components such as sand, gravel, concrete, and bricks due to their low cost and flexible operation.

[0003] Currently, most existing construction material transfer equipment used on construction sites is a simple hand-push structure, mainly consisting of a bucket to carry materials, a frame supporting the bucket, and wheels installed at the bottom of the frame. By manually pushing a push rod installed on the frame, the wheels are made to roll, thereby moving the bucket and the materials inside.

[0004] However, when existing equipment operates on slopes with a certain gradient, the center of gravity of the equipment and the grip angle of the push rod are fixed, making it difficult to adjust according to the slope. When going uphill, the center of gravity of the equipment shifts backward, and the operator needs to exert effort to lift the push rod to prevent the front of the vehicle from tilting and tipping over. When going downhill, the center of gravity of the equipment moves forward, and the operator needs to press down the push rod to resist the forward tilting trend and control the descent speed. This not only increases the labor intensity and operation difficulty of the operator, but also makes the equipment prone to tipping over due to instability of the center of gravity when the material is unevenly loaded or the slope is steep, causing material spillage or even personnel injury, affecting the safety and efficiency of slope transfer operations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a construction material transfer device for construction sites, aiming to improve the problem that the fixed center of gravity position and the fixed grip angle of the hand lever of the existing equipment not only increase the labor intensity and operation difficulty of the operator, but also make the equipment prone to tipping over due to instability of the center of gravity, thus affecting the safety and efficiency of slope transfer operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction material transfer device for construction sites, comprising a base plate, an mounting frame fixedly connected to the upper surface of the base plate, an axle provided on the lower surface of the base plate, a traveling wheel rotatably connected to both ends of the axle, a support frame symmetrically provided on the left and right sides of the outer wall of the base plate, and an adjustment component provided on the inner wall of the support frame;

A rotating shaft is rotatably connected to one end of the connecting rod. A connecting rod is rotatably connected to the outer wall of the rotating shaft. A rotating shaft is fixedly connected to one end of the connecting rod.

[0008] Furthermore, a support block is fixedly connected to the upper surface of the support frame, the outer wall of the rotating shaft is rotatably connected to the inner wall of the support block, and a push rod is fixedly connected to the other end of the rotating shaft.

[0009] Furthermore, a mounting plate is fixedly connected to the upper surface of the support block, a hydraulic rod is fixedly connected to the lower surface of the mounting plate, a connecting rod is fixedly connected to the output end of the hydraulic rod, and the two ends of the connecting rod are fixedly connected to the opposite side of the slide rod.

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.

[0026] Reference Figures 1-3This utility model provides an embodiment of a construction material transfer device for construction sites, including a base plate 1 for providing basic support for the equipment. A mounting frame 2 is fixedly connected to the upper surface of the base plate 1, and the mounting frame 2 is used to install transfer buckets 30 and other related components, providing an installation platform for the transfer buckets 30. A wheel axle 6 is provided on the lower surface of the base plate 1, and two wheels 7 are rotatably connected to both ends of the wheel axle 6. Support frames 3 are symmetrically arranged on the left and right sides of the outer wall of the base plate 1. An adjustment assembly is provided on the inner wall of the support frame 3, including a slide rod 13 and a guide rail 18. The outer wall of the guide rail 18 is fixedly connected to the inner wall of the support frame 3, and the inner wall of the slide rod 13 is slidably connected to the outer wall of the guide rail 18. An auxiliary wheel 14 is provided on the lower surface of the slide rod 13 for providing additional support points. A rotating shaft 12 is fixedly connected to one side of the outer wall of the slide rod 13, and a connecting rod 11 is rotatably connected to the outer wall of the rotating shaft 12. One end of the connecting rod 11 is rotatably connected to... There is a rotating shaft 10, and a connecting rod 9 is rotatably connected to the outer wall of the rotating shaft 10. One end of the connecting rod 9 is fixedly connected to a rotating shaft 4 for connecting the hand push rod 5 and the support block 8. The support block 8 is fixedly connected to the upper surface of the support frame 3. The outer wall of the rotating shaft 4 is rotatably connected to the inner wall of the support block 8. The other end of the rotating shaft 4 is fixedly connected to a hand push rod 5 for manually operating the force application point. The upper surface of the support block 8 is fixedly connected to a mounting plate 15. The lower surface of the mounting plate 15 is fixedly connected to a hydraulic rod 16. The hydraulic rod 16 is a hydraulic drive device, which provides linear telescopic power to drive the connecting rod 17, thereby controlling the position of the slide rod 13. This is common knowledge and will not be elaborated further here. The output end of the hydraulic rod 16 is fixedly connected to the connecting rod 17 for transmitting hydraulic power, thereby synchronizing the telescopic movement of the hydraulic rod 16 to the slide rods 13 on both sides. The two ends of the connecting rod 17 are fixedly connected to the opposite side of the slide rod 13.

[0027] Specifically, the traveling wheel 7 rotates in conjunction with the wheel axle 6 to support the movement of the equipment, achieving the effect of flexibly transporting building materials on construction sites. The slide bar 13 slides up and down in conjunction with the guide rail 18, so that the auxiliary wheel 14 can move down to prevent backward tilting when going uphill and lift up to prevent forward tipping when going downhill, achieving the effect of dynamically adjusting the center of gravity of the transfer bucket 30 and solving the safety hazards in slope transfer. The connecting rod 2 11 rotates in conjunction with the rotating shaft 3 12, thereby driving the connecting rod 1 9 to swing around the rotating shaft 4, realizing the effect of automatic angle adaptation of the push rod 5. The four-bar mechanism ensures that the push rod 5 is always consistent with the direction of force applied by the operator, optimizing the mechanical angle and improving the comfort of pushing and pulling.

[0028] Reference Figure 4 and Figure 5The upper surface of the mounting frame 2 has a sliding groove 19, which adopts a dovetail groove design, i.e., an isosceles trapezoidal cross section. The inclined surface of its inner wall is closely fitted with the trapezoidal outline of the guide rail 21. The guide rail 21 is slidably connected to the inner wall of the sliding groove 19. A connecting plate 20 is fixedly connected to the upper surface of the guide rail 21. A transfer bucket 30 for loading building materials is fixedly connected to the upper surface of the connecting plate 20. A locking block 22 is fixedly connected to one end of the guide rail 21. A groove is provided on one side of the locking block 22. A lock box 26 is fixedly connected to one side of the outer wall of the mounting frame 2. The outer wall of the locking block 22 is slidably connected to the inner wall of the lock box 26. A rotating shaft 4 is fixedly connected to the inner wall of the lock box 26. 29. A locking block 23 is rotatably connected to the inner wall of the rotating shaft 29. One end of the locking block 23 has a protrusion. A spring 24 is fixedly connected to one side of the outer wall of the locking block 23. The spring 24 is used to push the locking block 23 to reset. When the locking block 1 22 slides into the lock box 26, the spring 24 rebounds and resets the locking block 23 to lock the locking block 1 22, ensuring the reliability of the locking effect. One end of the spring 24 is fixedly connected to one side of the inner wall of the lock box 26. A pressing rod 25 is slidably connected to the inner wall of the lock box 26. One end of the pressing rod 25 is in contact with one side of the outer wall of the locking block 23. A screw 27 is provided on the inner wall of the mounting bracket 2. A nut 28 is threadedly connected to the outer wall of the screw 27.

[0029] Specifically, guide rail 21 slides within the slide groove 19 and is fixed to the transfer bucket 30 via connecting plate 20. Guide rail 21 moves horizontally in conjunction with slide groove 19, thereby driving the transfer bucket 30 in and out of mounting frame 2, achieving the effect of quick bucket replacement. Locking blocks 1 22 and 2 3 cooperate, sliding into locking box 26 when guide rail 21 is pushed forward. Its groove precisely engages with the protrusion of locking block 2 23, locking guide rail 21. Pressing rod 25 is used to manually release the lock, thereby pushing locking block 2 23 to rotate and compressing spring 24, achieving quick release of locking block 1 22. The operation is convenient and efficient. Screw 27 is inserted into the inner wall of mounting frame 2, and nut 28 is tightened to form a secondary safety, assisting in securing guide rail 2 21, thereby enhancing bucket stability, preventing loosening during transfer, and improving safety.

[0030] Working principle: When transporting building materials at a construction site, the building materials are first placed into the transfer bucket 30. Then, the operator applies a pushing or pulling force to the push rod 5, thereby causing the traveling wheel 7 and the auxiliary wheel 14 to rotate, thus changing the position of the transfer bucket 30 and realizing the transfer of building materials.

[0031] When there is a slope in the transfer route, the hydraulic rod 16 is operated to extend and retract, driving the connecting rod 17 to move the slide rod 13 up and down along the guide rail 18 inside the support frame 3, thereby adjusting the height of the auxiliary wheel 14 and changing the center of gravity of the transfer bucket 30. When going uphill, it moves down to prevent backward tilting, and when going downhill, it moves up to prevent forward tipping, eliminating the risk of equipment overturning when transferring on a slope. While the slide rod 13 slides, it drives the rotating shaft 12 to drive the connecting rod 11 to rotate. The connecting rod 11 drives the connecting rod 9 to rotate around the rotating shaft 4 through the rotating shaft 10, so that the angle of the push rod 5 automatically adapts to the height of the auxiliary wheel 14, making the direction of the operator's push and pull force more in line with the optimal mechanical angle and improving the comfort of operation.

[0032] For different building materials, the bucket can be quickly replaced. First, unscrew the nut 28, pull out the screw 27, and then press the pressing rod 25 to make the second locking block 23 rotate around the fourth rotating shaft 29 and compress the spring 24, thereby releasing the lock on the first locking block 22. Then, push out the second guide rail 21 along the slide groove 19 of the mounting frame 2 to remove the transfer bucket 30. Then, install the new bucket. The second guide rail 21 of the new bucket is pushed in along the slide groove 19. Then, the first locking block 22 slides into the lock box 26. At the same time, the spring 24 rebounds and pushes the second locking block 23 to reset, locking the first locking block 22 and completing the quick locking. Finally, insert the screw 27 and tighten the nut 28 to secure the second guide rail 21 and prevent the bucket from loosening during the transfer process.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
