Description

Technical Field

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

[0002] Building materials are the various materials used in construction projects. Common building materials include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, composite materials, etc. During the construction process, some building materials need to be transported by trolleys, such as cement, sand, glass, and insulation cotton.

[0003] However, traditional transport carts are mostly of fixed size, making it difficult to flexibly expand their capacity according to actual transport needs, resulting in low transport efficiency. During the transport of building materials, the placement of unloading tools (such as shovels) is not properly planned. Traditional transport carts do not have a dedicated tool storage structure, and construction workers often have to place unloading tools randomly on the cart. During transport, the tools are very easy to fall off due to shaking, affecting transport efficiency. Therefore, a building material transport device is proposed to address the above situation. Utility Model Content

[0004] The purpose of this utility model is to provide a building material handling device. Through the structural design of fixing blocks, positioning bolts, L-shaped plates and nylon mesh, the loading area of ​​the device can be quickly expanded to meet the temporary increase in handling volume. This avoids the problem of low loading efficiency caused by fixed trolley size. The expansion mechanism can be stored away when not in use, which greatly reduces the overall volume of the device, making it convenient for transportation and storage. This solves the problem that the size of traditional handling trolleys is mostly fixed, making it difficult to flexibly expand according to actual handling needs, resulting in low handling efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a building material handling device, including a base and an expansion mechanism. A storage box is fixed on the top of the base, and there is a gap between the storage box and the base. Fixing blocks are fixed on both side plates of the base.

[0007] There are two expansion mechanisms, each including an L-shaped plate that slides vertically on the base. The horizontal end of the L-shaped plate has two positioning holes. After the expansion mechanism slides away from the storage box, it cooperates with the side wall of the storage box to form a rectangular cavity. The fixing block is threaded with a positioning bolt, one end of which extends into the positioning hole.

[0008] Furthermore, the base is equipped with casters at the bottom and a push handle is fixed to one end of the top of the base.

[0009] Furthermore, a sliding plate is fixed to the top of the base below the storage box, and a groove is provided on the top of the sliding plate.

[0010] Furthermore, a slider is fixed to the bottom of the L-shaped plate, and the slider slides in conjunction with the groove.

[0011] Furthermore, multiple limiting grooves are provided on the top of the L-shaped plate along its length, and rubber pads are provided on the surface of the limiting grooves. Nylon mesh is fixed to both ends of the L-shaped plate, and one end of the nylon mesh is fixed to one side plate of the storage box.

[0012] Furthermore, a threaded hole is provided through the top of the fixing block, and the positioning bolt is threadedly engaged with the threaded hole.

[0013] This utility model has the following beneficial effects:

[0014] This utility model, through the structural design of a fixing block, positioning bolts, L-shaped plate and nylon mesh, allows for the rapid expansion of the device's loading area when additional materials or tools need to be moved. This meets the needs of temporarily increased handling volume and avoids the problem of low loading efficiency caused by the fixed size of the trolley. The expansion mechanism can be stored away when not in use, greatly reducing the overall size of the device and facilitating transportation and storage.

[0015] This utility model, by setting a limiting groove on the L-shaped plate, can control the hand-held parts of tools such as shovels, reducing the possibility of tools falling off during transportation due to bumps or shaking. It also avoids construction interruptions caused by frequent tool picking, thus improving the continuity and efficiency of transportation operations.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a building material handling device, including a base 1 and an expansion mechanism 4. A storage box 2 is fixed on the top of the base 1. The storage box 2 is used to store the main building materials. Its interior is treated with an anti-rust coating to extend its service life. The bottom of the base 1 is provided with moving wheels, and a push handle is fixed at one end of the top of the base 1.

[0024] The bottom-mounted casters are omnidirectional wheels equipped with brakes, a current technology that will not be elaborated upon here. The casters allow the transport device to maneuver flexibly in complex terrain at the construction site, while the brakes quickly secure the device after it has been moved to the designated location, preventing accidental slippage and ensuring safety during unloading. The push handle is ergonomically designed with a non-slip rubber layer, making it easy for workers to grip when pushing the device, reducing hand fatigue and improving operational comfort and convenience.

[0025] The storage box 2 is spaced apart from the base 1. Fixing blocks 3 are fixed on both sides of the base 1. A threaded hole is opened through the top of the fixing block 3, and the positioning bolt 30 is threadedly engaged with the threaded hole.

[0026] There are two expansion mechanisms 4. The expansion mechanism 4 includes an L-shaped plate 40, which slides in the vertical direction of the base 1. Specifically, a sliding plate 10 is fixed on the top of the base 1 below the storage box 2, and a groove 100 is provided on the top of the sliding plate 10.

[0027] The depth and width of the slide 100 are designed according to actual needs and the data are not unique. This can effectively limit the movement range of the slider 42 and prevent it from deviating or detaching during the sliding process.

[0028] The horizontal end of the L-shaped plate 40 is provided with positioning holes 401. There are two positioning holes 401. After the expansion mechanism 4 slides to the side away from the storage box 2, the expansion mechanism 4 and the side wall of the storage box 2 cooperate to form a rectangular cavity. The fixing block 3 is threaded with a positioning bolt 30, and one end of the positioning bolt 30 extends into the positioning hole 401.

[0029] When the L-shaped plate 40 slides to the side away from the storage box 2, the positioning bolt 30 is screwed into the positioning hole 401 through threaded engagement, forming a firm mechanical connection, which stably fixes the expansion mechanism 4 and ensures that it will not be displaced due to vibration or other factors during transportation.

[0030] A slider 42 is fixed to the bottom of the L-shaped plate 40. The slider 42 slides in conjunction with the slide groove 100. Multiple limiting grooves 400 are provided on the top of the L-shaped plate 40 along the length direction of the L-shaped plate 40. Rubber pads are provided on the surface of the limiting grooves 400. Nylon mesh 41 is fixed to both ends of the L-shaped plate 40. One end of the nylon mesh 41 is fixed to one side plate of the storage box 2.

[0031] The spacing of the multiple limiting grooves 400 is reasonably designed according to the size of common vehicle-mounted tools, which can accommodate various tools such as shovels and small hoes. The rubber pads on the surface of the limiting grooves 400 have good elasticity and friction, which can effectively prevent the tools from directly contacting the L-shaped plate 40 and causing wear while limiting the tools. The nylon mesh 41 fixed at both ends has high strength and tear resistance. One end is fixed to the side plate of the storage box 2. When the expansion mechanism 4 is unfolded, the nylon mesh 41 can form a barrier to further protect the building materials or tools placed in the expansion area and prevent them from falling from the side during transportation. At the same time, the nylon mesh 41 is soft and will not damage the materials and tools.

[0032] In its initial state, the L-shaped plate 40 of the expansion mechanism 4 is stored on the base 1 and slides in a compact manner through the slider 42 and the slide groove 100 of the slide plate 10, which facilitates the storage of the device. When it is necessary to increase the loading space, the operator holds the L-shaped plate 40 and slides the L-shaped plate 40 along the vertical direction of the base 1 to the side away from the storage box 2. After the L-shaped plate 40 moves into place, the positioning hole 401 at its horizontal end is aligned with the threaded hole on the fixing block 3. At this time, the operator screws the positioning bolt 30 into the threaded hole and through the positioning hole 401, and tightens it through the threaded engagement to firmly fix the L-shaped plate 40. The L-shaped plate 40 and the side wall of the storage box 2 cooperate to form a rectangular cavity, thus completing the expansion.

[0033] During loading, the storage bin 2 is used to store heavy building materials such as sand, gravel, and cement, while the expanded rectangular cavity can hold lightweight building materials such as wood and boards, or the ends of shovels and small hoes can be inserted into the limiting groove 400 at the top of the L-shaped plate 40. The rubber pad on the surface of the limiting groove 400 provides friction and cushioning to prevent the tools from shaking and wearing. At the same time, the nylon mesh 41 forms a barrier after the L-shaped plate 40 is unfolded to prevent materials or tools from falling from the side.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
