Description

Technical Field

[0001] This utility model relates to the field of handling tools, specifically a building demolition and handling device for engineering construction. Background Technology

[0002] In multi-story building demolition scenarios, the transfer of materials between different floors is a core pain point. While existing handling equipment can achieve inter-floor movement, the load-bearing mechanisms are mostly fixed structures with large volumes, making them difficult to store and transport when not in operation, increasing storage space and relocation costs. Furthermore, most load-bearing mechanisms lack effective protective measures on both sides, making it easy for materials to slip off the sides when moving them on stairs due to unstable stress. This not only causes material loss but also risks injuring construction workers below, further reducing the safety and efficiency of the handling process. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a building demolition and handling device for engineering construction, which solves the technical problems of existing handling devices being large in size, inconvenient to transport, and materials easily slipping during handling.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a building demolition and transportation device for engineering construction, including a trailer assembly, wherein a climbing step assembly is fixedly provided on one side near the bottom of the trailer assembly and a foldable and retractable load-bearing assembly is fixedly provided on the other side; The load-bearing component includes a fixed plate fixed to the bottom of the trailer assembly. The inner side of the fixed plate is hinged to a support plate via two hinges. The bottom of the support plate is fixed with two symmetrically arranged support frames. The support frames have a "V" shaped structure. The support plate is fixed with side support units that can be extended to both sides.

[0005] Preferably, the side support unit includes two sets of fixed blocks fixed to the support plate, and a connecting shaft is rotatably connected between the two fixed blocks on the same side. Multiple side support rods are fixed on the connecting shaft at equal intervals, and a stop bar fixed to the support plate is provided on the outer side of the side support rod.

[0006] Preferably, a fixing rope is tied between the two opposing side struts.

[0007] Preferably, the trailer assembly includes a frame, with a handle bar movably connected to the top of the frame. The two ends of the handle bar are slidably disposed within the frame. Springs are installed inside the handle bar near both ends, and locking blocks are fixed to the springs. The locking blocks are inserted into locking holes opened on the side wall of the frame.

[0008] Preferably, the climbing component includes two sets of fixed frames fixed to the bottom of the trailer component, and a rotating shaft is rotatably connected between the two sets of fixed frames. Wheel frames are installed at both ends of the rotating shaft, and three movable wheels are installed on the wheel frames, and the three movable wheels are distributed in a triangle.

[0009] Preferably, the fixing plate has an "L" shaped structure, and the bottom of the fixing plate is attached to the bottom of the support plate.

[0010] By employing the above technical solution, this utility model provides a building demolition and transportation device for engineering construction, which has at least the following beneficial effects: 1. The construction demolition and handling device used in this project features a movable load-bearing component at the bottom of the trailer assembly. With the help of hinges, the entire load-bearing component can be folded and stored to one side of the trailer assembly, reducing the overall volume. This allows for quick storage and transportation when not in operation, reducing storage space and relocation costs. Simultaneously, when the load-bearing component is unfolded, the side support unit provides lateral support for materials placed on the pallet, effectively reducing material slippage and increasing the amount that can be handled at one time. Furthermore, the fixing ropes secure the materials, further improving the safety of material handling.

[0011] 2. The construction demolition and handling device for this project uses a climbing component with three moving wheels at the bottom of the trailer assembly. The three moving wheels are arranged in a triangle to form a stable support triangle. When climbing stairs, the three moving wheels can contact different step surfaces respectively. Through the alternating support and rolling of the wheel set, the bumps during the climbing process can be greatly reduced, making the device more stable when going up and down stairs. It also has the advantages of saving time and effort and is suitable for flat ground and material handling on stairs. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0015] In the field of engineering construction, building demolition is a complex process involving the handling of large amounts of materials. Construction waste and recyclable building components generated during demolition need to be promptly transferred from the demolished floors to the ground or designated storage areas. However, current material handling processes face numerous technical challenges, severely restricting the efficiency and safety of demolition operations.

[0016] Due to the inherent technical drawbacks of existing technologies, such as inconvenience in transportation and the tendency for materials to slip during handling, please refer to... Figures 1-5 The construction demolition and handling device provided in this embodiment can be quickly stored and transported when not in operation, reducing the storage space and transfer costs of the equipment. At the same time, it can effectively reduce the problem of material slippage and increase the amount of material handled at one time. With the help of the fixing rope 355, the material can be tied and fixed, further improving the safety of material handling. The device includes a trailer assembly 1. A climbing component 2 is fixed on one side of the trailer assembly 1 near the bottom, and a foldable load-bearing component 3 is fixed on the other side. The trailer assembly 1 provides structural support for the whole. When in use, the material is placed on the load-bearing component 3. When moving the material on the stairs, the trailer assembly 1 is tilted at a certain angle. With the help of the climbing component 2, the whole can be moved gradually on the stairs.

[0017] Most existing load-bearing mechanisms are fixed flat plate structures that cannot be folded, occupy a large space when not in use, and are inconvenient for transportation and storage. To address this issue, please refer to... Figure 2 and Figure 3The load-bearing component 3 includes a fixed plate 31 fixed to the bottom of the carriage assembly 1. A tray 33 is movably hinged to the inner side of the fixed plate 31 via two hinges 32. Two symmetrically arranged support frames 34 are fixed to the bottom of the tray 33. The support frames 34 have a "V" shape structure. Side support units 35 that can be unfolded to both sides are fixed on the tray 33. By setting a movable load-bearing component 3 at the bottom of the carriage assembly 1, the entire load-bearing component 3 can be folded and stored to one side of the carriage assembly 1 under the action of the hinges 32, thereby reducing the overall volume. It can be quickly stored and transported in the non-operating state, reducing the storage space and transfer cost of the equipment. The design of the "V" shaped support frame 34 can prevent the entire device from moving when placed, making it more stable. Under the action of the side support unit 35, the material placed on the tray 33 is supported from the side, which can effectively reduce the problem of material slippage and increase the single handling capacity.

[0018] Most load-bearing structures lack effective protective measures on both sides. When moving materials on stairs, the unstable force makes it easy for materials to slip off the sides, causing not only material loss but also potential injury to workers below. This further reduces the safety and efficiency of material handling. For solutions to this problem, please refer to... Figure 3 The side support unit 35 includes two sets of fixing blocks 351 fixed to the pallet 33. A connecting shaft 352 is rotatably connected between the two fixing blocks 351 on the same side. Multiple side support rods 353 are fixed on the connecting shaft 352 at equal intervals. A stop bar 354 fixed to the pallet 33 is provided on the outer side of the side support rod 353. After the side support rod 353 is unfolded, it is tilted on both sides under the limiting action of the stop bar 354. When materials are placed, the side support rod 353 can provide lateral support for the materials, which can prevent the materials from slipping. The entire side support rod 353 can be folded onto the pallet 33, which also facilitates overall folding.

[0019] Furthermore, a fixing rope 355 is tied between the two opposing side support rods 353; under the action of the fixing rope 355, the material can be tied and fixed, further improving the safety of material handling.

[0020] The existing device has a fixed handle height, which cannot meet the needs of operators of different heights, easily causing them to bend over or stand on tiptoe during operation, increasing labor fatigue. To address this issue, the trailer assembly 1 includes a frame 11, with a handle 12 movably connected to the top of the frame 11. The two ends of the handle 12 are slidably disposed within the frame 11, and springs 13 are installed inside the handle 12 near both ends. Locking blocks 14 are fixed to the springs 13 and are inserted into locking holes 111 opened on the side wall of the frame 11. The handle 12 can be height adjusted by inserting the locking blocks 14 into different locking holes 111 to accommodate operators of different heights, improve operating comfort, and reduce strain on the waist and shoulders. The springs 13 drive the locking blocks 14 to automatically lock into the locking holes 111, ensuring that the handle 12 will not loosen when bearing weight, thus enhancing operational stability and safety.

[0021] Specifically, the climbing component 2 includes two sets of fixed frames 21 fixed to the bottom of the support frame component 1. A rotating shaft 22 is rotatably connected between the two sets of fixed frames 21. Wheel frames 23 are installed at both ends of the rotating shaft 22. Three movable wheels 24 are installed on the wheel frames 23, and the three movable wheels 24 are arranged in a triangular pattern. The three movable wheels 24 can form a stable support triangle. When climbing stairs, the three movable wheels 24 can contact different step surfaces respectively. Through the alternating support and rolling of the wheel sets, the bumps during the climbing process can be greatly reduced, making the device more stable when going up and down stairs, and has the advantages of saving time and effort.

[0022] Furthermore, the fixing plate 31 is made into an "L" shape, and the bottom of the fixing plate 31 is in contact with the bottom of the support plate 33. When the support plate 33 is unfolded, the bottom of the support plate 33 will contact the fixing plate 31. In this way, when the support plate 33 carries heavy objects, most of the weight will be distributed to the fixing plate 31, which can avoid the problem of the hinge 32 being deformed due to excessive force on the support plate 33, and avoid affecting the folding.

[0023] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
