A device for conveying waste in building construction projects

Abstract

This utility model discloses a waste conveying device for building construction projects, relating to the field of construction engineering technology. It includes a support frame, a waste hopper rotatably connected to the inner wall of the support frame, and a locking assembly located at the top of the support frame. The locking assembly is used to lock the waste hopper. The locking assembly includes a receiving crossbar, which is movably inserted into the side of the support frame near the top via a built-in insert rod. Through the synergistic action of the locking assembly (receiving crossbar, built-in insert rod, push connecting rod, C-shaped push frame, handle, limiting slot, auxiliary locking block, and pressure block), the waste hopper can be stably locked during waste loading and conveying. The receiving crossbar's support of the pressure block restricts the rotation of the waste hopper, and the limiting slot of the handle and the engagement of the auxiliary locking block further fix the position of the locking assembly, effectively preventing waste from falling due to accidental overturning of the waste hopper during waste conveying, thus improving conveying safety.

Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically to a device for conveying waste in building construction projects. Background Technology

[0002] In building construction projects, a large amount of debris (such as concrete blocks, broken bricks, and waste wood) is generated during the construction process. This debris needs to be promptly transported from the construction floors to designated storage areas to ensure a clean construction environment and construction safety. Existing debris conveying systems generally have the following problems:

[0003] Unreliable locking: The locking structure of the slag hopper in some devices is simple and is prone to failure due to vibration or uneven road surface during movement. Accidental overturning of the slag hopper can cause residue to fall out, which not only affects construction efficiency but may also cause safety accidents.

[0004] Unloading operations are labor-intensive: Traditional unloading devices often require manual lifting or the use of complex power mechanisms. Manual lifting is labor-intensive, while power mechanisms increase the cost and maintenance difficulty of the device, and are not suitable for space-constrained scenarios such as multi-story construction.

[0005] Insufficient mobility: The moving parts of some devices are poorly designed, making it difficult to turn or adapt to uneven construction ground. They are inconvenient to operate when moving in narrow areas such as corridors and elevator entrances, affecting the continuity of residue transportation.

[0006] Lack of buffer protection: When the slag hopper resets after unloading, it often collides hard with the supporting structure. Long-term use can easily lead to deformation and damage of the slag hopper or supporting structure, shortening the service life of the device. Utility Model Content

[0007] To address the problems mentioned in the background art, the purpose of this utility model is to provide a slag conveying device for building construction projects, which adopts a multi-locking structure (supporting the pressure block with the supporting crossbar + locking the limiting slot with the auxiliary locking block) to ensure that the slag hopper is stably locked during the conveying process, thus solving the problem of unreliable locking.

[0008] The design features a linkage structure with the unloading shaft as the rotation center. The locking can be released by operating the handle, and the slag hopper automatically unloads under the action of gravity, solving the problem of laborious unloading.

[0009] Equipped with casters, a push handle, and a side-pull push handle, the device's mobility is enhanced to adapt to complex construction scenarios.

[0010] Adding a buffer crossbar and rubber buffer sleeve (with springs can be added) reduces collision damage when the slag hopper resets, solving the problem of lack of buffer protection.

[0011] To achieve the above objectives, this utility model provides the following technical solution: a device for conveying waste in building construction projects, comprising a support frame;

[0012] Rotate the slag hopper connected to the inner wall of the support frame;

[0013] A locking assembly is installed at the top of the support frame to lock the slag hopper. The locking assembly includes a receiving crossbar, which is movably inserted into the side of the support frame near the top via a built-in insert. Both ends of the receiving crossbar are rotatably connected to a pushing connecting rod via mounting blocks. The end of the pushing connecting rod away from the receiving crossbar is rotatably connected to a C-shaped pusher, and the bottom end of the C-shaped pusher is rotatably connected to the upper surface of the support frame.

[0014] As a preferred embodiment of this utility model, the support frame has a movable insertion hole on one side near the top, the inner wall of the movable insertion hole is movably connected to the outer wall of the built-in insertion rod, and a handle is movably connected to one side of the C-shaped push frame.

[0015] As a preferred embodiment of this utility model, the inner wall of the grip is provided with a limiting groove, and the top of the support frame is fixedly connected with an auxiliary locking block that is adapted to the limiting groove.

[0016] As a preferred embodiment of this invention, the inner wall of the limiting slot is movably engaged with the outer wall of the auxiliary block.

[0017] In a preferred embodiment of this utility model, the side of the slag hopper near the top is rotatably connected to the inner wall of the support frame via a discharge shaft. A caster wheel is fixedly connected to the bottom of the support frame, and a buffer crossbar is fixedly connected to the inner wall of the support frame near the bottom. A rubber buffer sleeve is fitted onto the outer wall of the buffer crossbar.

[0018] As a preferred embodiment of this utility model, a pressure block is overlapped on the upper surface of the receiving crossbar, and the pressure block is fixedly connected to the side of the slag hopper near the top.

[0019] As a preferred embodiment of this utility model, a movable push handle is fixedly connected to one end of the support frame, and a side pull push handle is fixedly connected to the right side of the support frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model utilizes the synergistic effect of locking components (receiving crossbar, built-in insert rod, pushing connecting rod, C-shaped push frame, handle, limiting slot, auxiliary locking block, and pressure block) to stably lock the slag hopper during slag loading and conveying. The receiving crossbar supports the pressure block, limiting the rotation of the slag hopper. The limiting slot of the handle and the engagement of the auxiliary locking block further secure the position of the locking components, effectively preventing slag from falling due to accidental overturning of the slag hopper during slag conveying and improving conveying safety.

[0022] 2. During unloading, this utility model only requires operating the handle to unlock the locking component, and the slag hopper can then rotate around the unloading shaft under gravity to unload the material, without the need for additional power. The lever structure design of the U-shaped pusher and the pusher connecting rod reduces the operating force when unlocking, making the unloading process more labor-saving.

[0023] 3. This utility model uses casters at the bottom of the support frame in conjunction with a movable push handle and a side pull push handle to make the device flexible in turning and moving. It can achieve linear transport by pushing with the movable push handle and adjust the position by pulling with the side pull push handle, adapting to complex site environments such as corridors and construction areas in building construction.

[0024] 4. This utility model provides buffering when the slag hopper is reset by the buffer crossbar on the inner wall of the support frame and the rubber buffer sleeve (with springs added) on the outer wall, reducing the collision and impact between the slag hopper and the support frame, reducing component wear, and extending the overall service life of the device. The slag hopper is equipped with an inclined plate, which allows the residue to slide smoothly out along the inclined plate during unloading, avoiding residue residue and improving unloading efficiency.

[0034] Example 1

[0035] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a device for conveying waste in building construction projects, including a support frame 1;

[0036] Rotate the slag hopper 5, which is connected to the inner wall of the support frame 1;

[0037] The locking assembly is located at the top of the support frame 1 and is used to lock the slag hopper 5. The locking assembly includes a receiving crossbar 7, which is movably inserted into the side of the support frame 1 near the top via a built-in insert rod 8. Both ends of the receiving crossbar 7 are rotatably connected to a pushing connecting rod 9 via an mounting block. The end of the pushing connecting rod 9 away from the receiving crossbar 7 is rotatably connected to a C-shaped pusher 10. The bottom end of the C-shaped pusher 10 is rotatably connected to the upper surface of the support frame 1.

[0038] Specifically, through the coordinated action of the locking component, including the supporting crossbar 7, the built-in insert rod 8, the pushing connecting rod 9, the U-shaped pusher 10, the handle 11, the limiting slot 13, the auxiliary locking block 14, and the pressure block 12, the slag hopper 5 can be stably locked during slag loading and conveying. The supporting crossbar 7 supports the pressure block 12, limiting the rotation of the slag hopper 5. The locking slot 13 of the handle 11 and the auxiliary locking block 14 further fix the position of the locking component, effectively preventing the slag from falling due to accidental overturning of the slag hopper 5 during slag conveying, thus improving conveying safety.

[0039] Example 2

[0040] The second embodiment of this utility model provides a technical solution: a movable insertion hole is provided on the side of the support frame 1 near the top, the inner wall of the movable insertion hole is movably connected to the outer wall of the built-in insertion rod 8, and a handle 11 is movably connected to one side of the C-shaped push frame 10.

[0041] The inner wall of the grip 11 has a limiting slot 13, and the top of the support frame 1 is fixedly connected with an auxiliary block 14 that is adapted to the limiting slot 13.

[0042] The inner wall of the limiting slot 13 is movably engaged with the outer wall of the auxiliary card block 14.

[0043] Example 3

[0044] The third embodiment of this utility model provides a technical solution: the side of the slag hopper 5 near the top is rotatably connected to the inner wall of the support frame 1 via the unloading shaft 6, the bottom of the support frame 1 is fixedly connected to the universal wheel 2, the inner wall of the support frame 1 near the bottom is fixedly connected to the buffer crossbar 15, and the outer wall of the buffer crossbar 15 is fitted with a rubber buffer sleeve.

[0045] A pressure block 12 is attached to the upper surface of the crossbar 7, and the pressure block 12 is fixedly connected to the side of the slag hopper 5 near the top.

[0046] A movable push handle 3 is fixedly connected to one end of the support frame 1, and a side pull push handle 4 is fixedly connected to the right side of the support frame 1.

[0047] Specifically, the buffer crossbar 15 on the inner wall of the support frame 1 and the rubber buffer sleeve (with springs) on the outer wall can provide buffering when the slag hopper 5 is reset, reducing the collision and impact between the slag hopper 5 and the support frame 1, reducing component wear, and extending the overall service life of the device. The slag hopper 5 is equipped with an inclined plate, which allows the residue to slide smoothly out along the inclined plate during unloading, avoiding residue residue and improving unloading efficiency.

[0048] Example 4

[0049] The fourth embodiment of this utility model provides a technical solution: the universal wheel 2 is made of high-strength polyurethane material, and the wheel core is made of No. 45 steel. It has the characteristics of wear resistance and strong load-bearing capacity, and can bear a weight of not less than 500 kg, adapting to the rough ground of the construction site.

[0050] The slag hopper 5 is made of Q235 carbon structural steel welded together, with a wall thickness of 3-5mm. The inner wall is coated with a wear-resistant ceramic coating with a thickness of 0.5-1mm to reduce the wear of the inner wall by the residue.

[0051] The unloading shaft 6 is rotatably connected to the inner wall of the support frame 1 by a deep groove ball bearing (model 6204). The outer ring of the bearing is interference-fitted with the support frame 1, and the inner ring is interference-fitted with the unloading shaft 6, ensuring smooth rotation of the slag hopper 5 and reducing frictional resistance.

[0052] Working principle:

[0053] The working principle of this waste conveying device used in building construction projects is as follows:

[0054] During slag loading, the device can be moved to the slag loading position by pushing the movable push handle 3 and using the universal wheels 2 at the bottom of the support frame 1. After the slag is loaded into the slag hopper 5, the locking component locks the slag hopper 5 to ensure stable conveying. At this time, the receiving crossbar 7 is movably inserted into the movable insertion hole near the top of the support frame 1 through the built-in insert rod 8. The pressure block 12 near the top of the slag hopper 5 overlaps on the receiving crossbar 7, and the receiving crossbar 7 provides support for the pressure block 12. At the same time, the handle 11 on one side of the C-shaped push frame 10 is movably engaged with the auxiliary locking block 14 at the top of the support frame 1 through the limiting slot 13 on its inner wall, further fixing the position of the locking component and preventing the slag hopper 5 from rotating accidentally.

[0055] During the conveying process, the device can be moved by moving the push handle 3 or pulling the push handle 4 in conjunction with the caster wheel 2 to realize the transfer of residue.

[0056] During unloading, pull the handle 11 to disengage the limiting slot 13 from the auxiliary locking block 14, and then push the handle 11 to drive the C-shaped pusher 10 to rotate and lift around the upper surface of the support frame 1. When the C-shaped pusher 10 rotates, the end away from the handle 11 drives the push connecting rod 9 to move forward. The push connecting rod 9 pushes the receiving crossbar 7 to move laterally along the direction of the inner insert rod 8 and the movable insertion hole of the support frame 1 through the mounting block. After the receiving crossbar 7 moves laterally, its supporting function on the pressure block 12 is released. Under the gravity of itself and the internal residue, the slag hopper 5 rotates downward around the unloading shaft 6 (the slag hopper 5 is rotatably connected to the inner wall of the support frame 1 through the unloading shaft 6). The residue in the slag hopper 5 slides out along its internal inclined plate to complete the unloading. The buffer crossbar 15 (with a rubber buffer sleeve on the outer wall, and a spring can be installed on the buffer crossbar 15 to enhance the buffering effect) near the bottom inner wall of the support frame 1 buffers the slag hopper 5, preventing the slag hopper 5 from colliding hard with the support frame 1. During the unloading process, the side pull handle 4 can be pulled to move away from the slag hopper 5 to assist in adjusting the unloading position.

[0057] After unloading, reset the slag hopper 5. A lifting groove can be opened on the inner wall of 5, or a lifting handle can be installed in a suitable position to facilitate its reset. Then, reverse the operation of the handle 11 to reset the receiving crossbar 7. The pressure block 12 is re-attached to the receiving crossbar 7, and the limiting slot 13 and the auxiliary locking block 14 are re-engaged to complete the re-locking of the slag hopper 5 for the next slag loading and conveying.

[0058] In summary, through the coordinated action of the locking components (receiving crossbar 7, built-in insert rod 8, pushing connecting rod 9, U-shaped pusher 10, handle 11, limiting slot 13, auxiliary locking block 14, and pressure block 12), the slag hopper 5 can be stably locked during slag loading and conveying. The receiving crossbar 7 supports the pressure block 12, limiting the rotation of the slag hopper 5. The limiting slot 13 of the handle 11 and the locking block 14 further fix the position of the locking components, effectively preventing the slag from falling due to accidental overturning of the slag hopper 5 during slag conveying, thus improving conveying safety.
