Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, specifically to a material transport device and method for scaffolding. Background Technology

[0002] During the main structure construction of a building project, after the full-span scaffolding is dismantled, it is necessary to promptly clear away the formwork, timber, steel pipes, and other materials inside to provide a work area for secondary structure construction. Currently, forklifts and other machinery are conventionally used for material transportation during scaffolding dismantling. However, mechanical transportation has significant drawbacks: firstly, the rental and operating costs of machinery are high; secondly, forklifts are difficult to maneuver inside dense scaffolding, resulting in low transportation efficiency; and thirdly, when there are height differences or thresholds in the construction foundation, forklifts cannot pass directly and additional ramps must be built. This process not only increases the workload but also poses a safety hazard of forklifts tipping over when crossing ramps.

[0003] Therefore, there is an urgent need for a low-cost, high-efficiency, and high-safety material transportation method suitable for the complex environment inside scaffolding. Summary of the Invention

[0004] This invention is made to solve the above-mentioned technical problems. Its purpose is to provide a material transportation device inside scaffolding, so as to solve the problems of high cost, low efficiency, many limitations due to space and ground conditions, and insufficient safety when using forklifts and other tools to transfer materials inside the scaffolding.

[0005] Another object of the present invention is to provide a transportation method that ensures the safety and efficiency of transportation operations.

[0006] According to one embodiment of the present invention, a material transport device for internal scaffolding is provided, comprising: a track frame, a traveling crane assembly disposed on the track frame, and a connecting assembly disposed on the traveling crane assembly; wherein, The driving assembly includes two driving brackets arranged at the front and rear. The connecting assembly connects the two travel brackets into a single unit.

[0007] In one embodiment, each of the travel brackets includes: a support beam and two travel wheels mounted on the bottom of the support beam; wherein, The traveling wheel is a roller with a groove on its outer circumference, used to roll on the track frame.

[0008] In one embodiment, the track frame includes: a plurality of support frames, a horizontal connecting rod disposed between the plurality of support frames, a track support horizontal rod disposed at the upper end of the horizontal connecting rod, a pad disposed on the track support horizontal rod, and a track steel pipe disposed on the pad; wherein, The track frame is erected on the passageway removed from inside the scaffolding; The grooves of the traveling wheels match the rail steel pipe.

[0009] In one embodiment, the pad is a wooden block or a plastic block.

[0010] In one embodiment, a roller is provided at the center of the traveling wheel, and a U-shaped component is provided between the traveling wheel and the roller. The U-shaped component is welded to the bottom of the support beam.

[0011] As one implementation, a fixed square hole is provided at each end of the support beam.

[0012] As one embodiment, one end of the connecting component is provided with a U-shaped groove for engaging the support beam, and the other end is provided with a plurality of connecting holes corresponding to the fixed square hole, and a fastener is provided that can be inserted into the fixed square hole and the connecting hole.

[0013] In one embodiment, the support frame is formed by connecting two vertical poles and one horizontal pole with fasteners.

[0014] In one embodiment, the track steel pipe is configured as two pipes, wherein, The distance between the two rail steel pipes is the same as the distance between the two traveling wheels on the traveling support.

[0015] A method for transporting internal materials using the aforementioned scaffolding internal material transport device includes the following steps: S1: Assemble the track trolley by connecting the two traveling brackets front and rear using the connecting component; S2: Set up the transport track and place the assembled track trolley onto the transport track; S3: Load and secure the material to be transported onto the connecting assembly of the track trolley; S4: The track trolley is manually pulled to run along the transport track, transporting materials from inside the scaffolding to the exit.

[0016] Based on the above description and practice, it is clear that the advantages of the scaffolding internal material transport device and method in this invention compared to traditional scaffolding internal material transport devices and methods are as follows: 1. No need to use large machinery such as forklifts, saving rental and fuel costs; the rail frame is built using steel pipes from scaffolding that is about to be dismantled, realizing the recycling of resources and greatly reducing material costs.

[0017] 2. Rail transport is smooth and labor-saving, and its efficiency is significantly improved compared to manual handling or mechanical transport that is limited by space.

[0018] 3. By setting up tracks, the limitations of transportation caused by ground elevation differences, thresholds, and other obstacles are perfectly overcome, making it suitable for various complex construction site environments.

[0019] 4. It avoids the safety risks of operating heavy machinery in narrow spaces and on slopes. The pure manual towing method is more controllable and safer.

[0020] 5. The components used in the device are simple and easy to manufacture. The track erection method is easy to master, making it easy to promote and apply quickly on the construction site. Attached Figure Description

[0030] Unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] According to one embodiment of the present invention, a material transport device for internal scaffolding is provided. This device is mainly used in the scaffolding dismantling stage of construction projects, solving the problems of difficult, costly, and inefficient internal material transport. The following is in conjunction with... Figures 1 to 6 The material transport device inside the scaffolding is described.

[0032] The material transport device inside the scaffolding in this embodiment mainly includes: a track frame, a trolley assembly, and connecting components. The track frame is erected and fixed using the internal space of the scaffolding. The connecting components connect the various parts of the trolley assembly into a whole, and also bear and secure the materials to be transported. These three parts—the track frame, the trolley assembly, and the connecting components—are organically combined to form a complete transport system.

[0033] The track frame can be erected directly using the passageway space partially modified from full-span scaffolding, without the need for additional foundations or support points. The traveling mechanism consists of two independent front and rear traveling supports 11. This split structure gives the device a certain degree of flexibility and the ability to navigate curves. The connecting component is the connecting part that connects the two traveling supports 11. It not only serves a simple connecting function but also forms a platform, allowing the two traveling supports 11 to move synchronously and share the load, thereby integrating the dispersed components into a stable and reliable transportation unit.

[0034] Each traveling support 11 includes a support beam and two traveling wheels 12 mounted on the bottom of the support beam. Each traveling wheel 12 is a roller with grooves on its outer circumference for rolling on the track frame. The support beam, as the main load-bearing component, is typically made of flat steel 100 mm wide and 6 mm thick. This specification of support beam is readily available on the construction site and possesses sufficient rigidity. The two traveling wheels 12 are symmetrically mounted at both ends of the bottom of the support beam, directly contacting the track. The outer circumference of the traveling wheel 12 is machined with grooves, the shape of which matches the arc-shaped outer surface of the track steel pipe 22. When the device is placed on the track, the grooves securely engage with the track steel pipe 22, serving as guides and preventing derailment. This ensures that the trolley, under manual traction, can travel in a straight line or smoothly through slight curves along a predetermined route without slipping off the side.

[0035] Furthermore, the erection of the track frame first requires working within a dense, full-span scaffold. During construction, some members are carefully removed to create a passage wide enough to accommodate the transport device. Next, the track foundation is constructed within this passage. Support frames 21 serve as the basic pillars of the track, quickly assembled from standard scaffolding steel pipes and fasteners. To ensure track stability, several support frames 21 are arranged at regular intervals within the passage. These support frames 21 are then tightly connected together using horizontal connecting rods and fasteners, forming a stable overall frame to prevent individual support frames 21 from shifting. A track support horizontal bar is erected above the support frames 21. To adjust the track height and ensure even stress on the track steel pipes 22, pads are placed on the track support horizontal bar. Finally, two parallel track steel pipes 22 are precisely placed on the pads. The grooves on the traveling wheels 12, in conjunction with the track steel pipes 22, ensure a smooth and stable transport process.

[0036] Furthermore, the pads allow for fine-tuning of height and cushioning. In practice, the most commonly used material is timber, readily available on construction sites, due to its ease of processing, low cost, and degree of elasticity, which can absorb some vibration. It can be cut into different thicknesses as needed. Another viable option is a sufficiently strong plastic block, which offers advantages such as durability and uniform specifications. The pads allow construction workers to flexibly adjust the height of the track steel pipes 22 to address minor unevenness in the ground, ensuring that the two track steel pipes 22 are always on the same horizontal plane, preventing bumps or jamming during trolley operation.

[0037] Furthermore, a roller is provided at the center of each traveling wheel 12, and a U-shaped component 13 is provided between the traveling wheel 12 and the roller. The U-shaped component 13 is welded to the bottom of the support beam. Each traveling wheel 12 has a roller at its center, allowing the traveling wheel 12 to rotate freely around the roller. The U-shaped component 13 can be a U-shaped steel clamp. The two ends of the roller are fixed between the two side arms of the U-shaped component 13. Then, the base of the U-shaped component 13 of this assembly is firmly welded to the bottom of the support beam. This welding installation method is not only simple and reliable, but also, because the U-shaped component 13 provides a certain amount of space, allows the traveling wheel 12 to produce a slight adaptive oscillation when encountering slight unevenness in the track, improving the trolley's passability on the track.

[0038] Furthermore, fixing square holes 15 are provided at both ends of the support beam. The fixing square holes 15 enable quick, tool-free connection. The size of the fixing square holes 15 is set according to construction needs, and the fixing square holes 15 can form a tight fit with their matching fasteners 16 (such as a small square steel piece). The fixing square holes 15 provide an interface for fixing the connecting components to the support beam, enabling rapid assembly and disassembly of the device.

[0039] Furthermore, one end of the connecting assembly is provided with a U-shaped groove 17 for engaging the support beam, and the other end is provided with multiple connecting holes corresponding to the fixed square holes 15, and a fastener 16 is provided for insertion into the fixed square holes 15 and the connecting holes. The connecting assembly is typically made of a strip of steel plate. One end of it is welded or bent to form an open U-shaped groove 17. During assembly, the support beam of the front travel bracket 11 is simply pushed directly into this U-shaped groove 17 to complete the quick connection of the front end, which is very convenient. The other end of the connecting assembly has multiple connecting holes at certain intervals, which correspond to the fixed square holes 15 on the support beam of the rear travel bracket 11. When it is necessary to connect the rear bracket, simply align the holes and insert the fastener 16 into the hole. The baffle prevents the fastener 16 from falling out of the hole. The fastener 16 is a small square steel with a baffle on the top. The connecting assembly can fine-tune the spacing between the front and rear travel brackets 11 according to the length of the transported material, enhancing the adaptability of the device. At the same time, the connecting component itself also forms a long platform that can be directly used to bind and support long strip materials such as steel pipes and timber.

[0040] Furthermore, the specific construction of the support frame 21 makes full use of existing resources. Each support frame 21 consists of a simple "gate"-shaped frame: two uprights stand vertically on the ground, and a horizontal bar is connected to the top of the two uprights by right-angle fasteners. The "gate"-shaped frame ensures the reliability of the support frame 21's strength, and the fasteners provide a secure connection when connected to other parts of the track frame.

[0041] Furthermore, the spacing between the track steel pipes 22 matches the spacing between the traveling wheels 12. When setting up the track, precise measurements must be taken using tools such as a measuring tape to ensure that the inner distance between the two track steel pipes 22 is completely consistent with the distance between the center lines of the grooves of the two traveling wheels 12 on the front or rear traveling support 11. If the distance is too large, the grooves of the traveling wheels 12 will not effectively fit with the track steel pipes 22, causing the trolley to sway left and right and easily derail; if the distance is too small, the traveling wheels 12 will be stuck by the track steel pipes 22 and unable to move forward. Therefore, matching the spacing between the track steel pipes 22 and the traveling wheels 12 ensures that the trolley wheels always roll along the correct path on the track.

[0042] Furthermore, a method for transporting internal materials using the aforementioned scaffolding internal material transport device, ensuring the safety and efficiency of the transport operation, includes the following steps: S1: Connect the two traveling brackets 11 front and rear to assemble the track trolley 1 using the connecting component 14; S2: Set up the transport track 2 and place the assembled track trolley 1 on the transport track 2; S3: Load and secure the material to be transported onto the connecting assembly 14 of the track trolley 1; S4: The track trolley 1 is manually pulled to run along the transport track 2 to transport materials from inside the scaffolding to the exit.

[0043] First, the construction workers placed two travel brackets 11, each already equipped with travel wheels 12, one behind the other on the ground, and then connected them using a connecting assembly. The front support beam was secured to the front end using a U-shaped groove 17, and the rear support beam was fixed to the connecting assembly using insert fasteners 16. After verifying the connection was secure, the complete track trolley 1 was assembled.

[0044] Then, along the planned transport route, the internal passageways of the scaffolding are removed. Next, the support frame 21 is installed sequentially, the horizontal bars are connected, and the pads are placed. Finally, the two track steel pipes 22 are precisely laid. After laying, the unloaded trolley should be manually pushed back and forth on the track for a short distance to check for any jamming or abnormal noise, ensuring that the track is laid flat and stable.

[0045] Secondly, the steel pipes, timber and other materials that need to be transported are neatly arranged and tightly tied to the connecting component (i.e. the long strip steel plate) of the track trolley 1 with wire or hemp rope.

[0046] Finally, one or two workers push the trolley from the front using ropes or by hand. Because the track reduces most of the frictional resistance, workers don't need to exert much effort to move the material-loaded trolley smoothly. The trolley will then safely transport the materials from deep within the scaffolding to the external storage point along the pre-set track.

[0047] By repeating the above four steps, the removal of materials inside the scaffolding can be completed efficiently and safely.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
