Description

Technical Field

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

[0002] On construction sites, the transfer and handling of materials is a key link in ensuring the progress of the project. In order to improve the efficiency of material transportation, various construction transportation devices, such as handcarts or electric material carts, have been widely used.

[0003] However, existing construction transport equipment is usually designed in a relatively fixed manner, and the material containers used to load materials in these transport equipment often have a constant loading volume.

[0004] This fixed-volume design makes it inflexible in practical applications. When a large amount of materials need to be transported at the construction site, operators must use the transport device to make multiple round trips, which significantly reduces work efficiency. When only a small amount of materials need to be transported, using a fixed large-volume transport vehicle is not flexible enough and will result in a waste of transport capacity. The existing transport device cannot dynamically adjust its loading volume according to the actual loading requirements of the materials.

[0005] Therefore, this utility model proposes a construction transportation device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of fixed material box volume, inability to flexibly meet the needs of transporting different batches of materials in the existing construction transportation device, resulting in low transportation efficiency, this utility model aims to provide a construction transportation device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a construction transportation device, including: a material box, movable wheels installed at the bottom of the material box, and a control rod fixedly connected to the side wall of the material box and electrically connected to the movable wheels. The construction transportation device also includes an adjustment mechanism.

[0008] The adjustment mechanism includes a recycling tank formed within the wall of the material bin, and an extension plate that can be slidably housed within the recycling tank.

[0009] Furthermore, the adjustment mechanism also includes an electric telescopic rod, a limiting plate, a rubber pad, and a protective cover. One end of the electric telescopic rod is fixed inside the material box, and the other end is connected to the extension plate, which is used to drive the extension plate to slide in the recycling tank. The limiting plate is fixedly installed at the opening of the recycling tank away from the inside of the material box, which is used to block and limit the extension plate when it extends, preventing it from extending excessively. The rubber pad is fixed at the outlet of the recycling tank and is located on the side of the limiting plate facing the extension plate, which is used to buffer the impact. The protective cover is fixed on the material box and covers the outside of the electric telescopic rod, which is used to prevent the electric telescopic rod from being bumped by external objects.

[0010] Preferably, the construction transport device further includes a protective mechanism, which includes a cover plate that can be opened and closed to cover the top opening of the material box to prevent materials inside the material box from falling out during transport.

[0011] Preferably, as a specific implementation, the cover plate is designed as two pieces, which are arranged side by side and jointly seal the top opening of the material box to accommodate the extended state of the material box after adjustment by the adjustment mechanism.

[0012] Preferably, the protective mechanism further includes a hinge, and the cover is rotatably connected to the top edge of the material box via the hinge to realize the opening and closing of the cover relative to the material box.

[0013] Preferably, the protective mechanism further includes a handle fixed to the top surface of the cover plate, which is used to facilitate the operator to hold and open or close the cover plate.

[0014] Preferably, to improve sealing reliability, magnetic strips are fixed to the bottom edge of the cover and the top edge of the material box. When the cover is closed, the magnetic strip at the bottom of the cover and the magnetic strip at the top of the material box attract and fix each other, preventing the cover from opening due to transportation bumps.

[0015] Preferably, for ease of observation, the cover plate has a through hole and an observation plate is fixedly installed thereon. The observation plate is made of transparent material, allowing operators to check the internal materials without opening the cover plate.

[0016] Preferably, to improve safety, the control lever is integrated with a circular alarm, which is electrically connected to a weight sensor located at the bottom of the material bin, and is used to alert the operator when the material bin is loaded to a predetermined level.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting a control lever and a moving wheel electrically connected to it, allows the operator to control the moving wheel to achieve electric driving through the control lever, and is equipped with a circular alarm to remind the user of overload. It solves the problems of existing transportation devices that rely on manual pushing, are time-consuming and labor-intensive when the material is heavy, have low efficiency and safety hazards, and achieve the goals of saving manpower, convenient operation, improving transportation efficiency and safety.

[0019] 2. This utility model, by setting an adjustment mechanism, including an electric telescopic rod, an extension plate that can slide and be accommodated in the recycling trough, a limiting plate, a rubber pad, and a protective cover, solves the defects of the existing technology where the volume of the transport box is fixed and cannot flexibly meet the transportation needs of different batches of materials. It achieves the goal of flexibly adjusting the volume of the material box, improving the single loading capacity and transportation efficiency, and ensures the stability and durability of the adjustment mechanism through the limiting, buffering, and protective structures.

[0020] 3. This utility model, by setting up a protective mechanism, includes two cover plates, a hinge, an observation plate, a handle, and corresponding magnetic strips. The cover plates cover the top of the material box, and the magnetic strips are used for adsorption and fixation. This solves the problem in the prior art that open transport boxes will spill materials when traveling on bumpy roads at construction sites, causing waste and safety hazards. It effectively seals the box, prevents materials from falling out due to bumps, improves transport adaptability, and enhances the ease of operation through the observation plate and handle.

[0027] 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.

[0028] Example:

[0029] Please refer to Figures 1 to 4 This utility model provides a construction transportation device, which aims to solve the problems of existing construction transportation devices, such as heavy manual pushing burden, low transportation efficiency, inflexible loading of fixed volume, and material spillage during transportation on bumpy roads.

[0030] like Figure 1 and Figure 2 As shown, a construction transportation device includes a material box 1 and a set of casters 2 installed at the bottom of the material box 1. The material box 1 is used to load construction materials, and the casters 2 are used to support the material box 1 and move it on the ground. The device also includes a control lever 3, which is fixedly connected to the side wall of the material box 1 and electrically connected to the casters 2. The operator controls the casters 2 to move forward, backward, and left and right using the smart button on the control lever 3.

[0031] In order to load a large amount of material at once, the material box 1 includes an adjustment mechanism 4, such as... Figure 4 As shown, the adjustment mechanism 4 includes a recycling trough 404 formed in the wall of the material box 1, and an extension plate 402 that can be slidably housed in the recycling trough 404. The adjustment mechanism 4 also includes an electric telescopic rod 401. One end of the electric telescopic rod 401 is fixed inside the material box 1, and the other end of the electric telescopic rod 401 is connected to the extension plate 402. The electric telescopic rod 401 is used to drive the extension plate 402 to slide along its length in the recycling trough 404, so that the extension plate 402 extends or retracts, thereby enabling the material box 1 to be adjusted and extended left and right to change the volume of the material box 1.

[0032] To ensure the stability and safety of the adjustment mechanism 4, the adjustment mechanism 4 also includes a limiting plate 403. The limiting plate 403 is fixedly installed at the opening of the recycling tank 404 away from the inside of the material box 1. When the extension plate 402 extends, the limiting plate 403 blocks and limits it to prevent the extension plate 402 from extending excessively and detaching from the recycling tank 404. The adjustment mechanism 4 also includes a rubber pad 406. The rubber pad 406 is fixed at the outlet of the recycling tank 404 and is located on the side of the limiting plate 403 facing the extension plate 402. When the extension plate 402 retracts or moves, the rubber pad 406 is used to buffer the impact generated by the extension plate 402 colliding with the inside of the box or the limiting plate 403 for a long time, preventing the limiting plate 403 from being damaged. The adjustment mechanism 4 further includes a protective cover 405. The protective cover 405 is fixed on the material box 1 and covers the outside of the electric telescopic rod 401. The protective cover 405 can prevent external objects from bumping into the electric telescopic rod 401.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The protective mechanism 5 includes a cover plate 501, which can be opened and closed to cover the top opening of the material box 1 to prevent the material inside the material box 1 from falling out during transportation. In order to adapt to the extended state of the material box 1 after adjustment by the adjustment mechanism 4, the cover plate 501 is designed as two pieces, and the two cover plates 501 are arranged side by side and jointly seal the top opening of the material box 1.

[0034] To enable the opening and closing of the cover 501, the protective mechanism 5 also includes a hinge 502. The cover 501 is rotatably connected to the top edge of the material box 1 via the hinge 502. The protective mechanism 5 further includes a handle 505, which is fixed to the top surface of the cover 501 for easy gripping and opening or closing of the cover 501 by the operator.

[0035] To ensure that the cover 501 remains closed during transportation, magnetic strips 504 are fixed to the bottom edge of the cover 501 and the top edge of the material box 1. When the cover 501 is closed, the magnetic strips 504 at the bottom of the cover 501 and the magnetic strips 504 at the top of the material box 1 attract and fix each other, preventing the cover 501 from opening accidentally due to transportation bumps.

[0036] To facilitate operators in inspecting the internal materials, a through hole is provided on the cover plate 501 and an observation plate 503 is fixedly installed thereon. The observation plate 503 is made of transparent material, so operators do not need to open the cover plate 501 to inspect the internal materials through the observation plate 503.

[0037] In addition, to enhance safety, a circular alarm is integrated on the control lever 3. The circular alarm is electrically connected to a weight sensor located at the bottom of the material bin 1, which is used to alert the operator when the material bin 1 is loaded with material to a predetermined level.

[0038] As a preferred embodiment, in order to accommodate the extended state of the material box 1 after adjustment by the adjustment mechanism 4, the cover plate 501 is designed as two pieces, with the two cover plates 501 arranged side by side and jointly sealing the top opening of the material box 1;

[0039] In a preferred embodiment, to enable the opening and closing of the cover 501 relative to the material box 1, the protective mechanism 5 further includes a hinge 502, and the cover 501 is rotatably connected to the top edge of the material box 1 via the hinge 502.

[0040] As a preferred embodiment, to facilitate the operator to hold and open or close the cover plate 501, the protective mechanism 5 also includes a handle 505, which is fixed to the top surface of the cover plate 501.

[0041] As a preferred embodiment, in order to prevent the cover 501 from opening due to transportation bumps, magnetic strips 504 are fixed to the bottom edge of the cover 501 and the top edge of the material box 1 respectively. When the cover 501 is closed, the magnetic strips 504 at the bottom of the cover 501 and the magnetic strips 504 at the top of the material box 1 are attracted and fixed to each other.

[0042] As a preferred embodiment, to facilitate operators to check the internal materials without opening the cover plate 501, the cover plate 501 is provided with a through hole and an observation plate 503 is fixedly installed thereon. The observation plate 503 is made of transparent material.

[0043] Working principle: Construction materials are loaded into the material box 1. The intelligent button on the control lever 3 on the right side of the material box 1 controls the forward, backward, left and right directions of the moving wheels 2, avoiding the problem of the vehicle being unable to be pushed manually. At the same time, in order to load more materials at once, the box body is expanded by the adjustment mechanism 4. The extension plate 402 is adjusted inside the recycling tank 404 by the electric telescopic rod 401, so that the material box 1 can be adjusted and extended left and right. Meanwhile, the protective cover 405 can prevent external objects from hitting the electric telescopic rod 401. The limiting plate 403 prevents excessive extension, which may lead to poor load-bearing capacity in the middle. A rubber pad 406 is placed at the outlet of the recycling tank 404, mainly to prevent the electric telescopic rod 401 from driving the extension plate 402 to collide with the inside of the box for a long time, which may damage the limiting plate 403. When the material inside the material box 1 is loaded to a certain extent, the circular alarm on the control lever 3 will remind the operator. The overall mechanism improves the efficiency of building material transportation and the safety of use.

[0044] Furthermore, to prevent materials from falling out of the material box 1 due to road bumps during transportation, the cover plate 501 in the protective mechanism 5 is used for sealing. At the same time, since the box body can extend, the cover plate 501 is designed as two. The operator does not need to open the cover plate 501 to check the internal material condition. The handle 505 and hinge 502 can be used to open and close the cover plate 501 more conveniently. The magnetic strip 504 at the bottom of the cover plate 501 and the magnetic strip 504 at the top of the material box 1 are used to fix the two together, preventing the cover plate 501 from opening due to bumps during transportation. The overall mechanism improves the ease of operation and transportation adaptability.
