Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, specifically an adjustable cement transfer device for engineering construction. Background Technology
[0002] During engineering construction, cement is an important building material, and its transportation directly affects construction efficiency and cost control. Cement transportation devices for engineering construction are key equipment to achieve efficient transportation of cement from storage points to construction sites. Among them, electric flatbed carts have become important equipment for short-distance transportation of bagged cement (such as from warehouses to construction sites, trucks to storage areas, etc.) due to their advantages such as convenient operation, stable power, and adaptability to narrow spaces. They play an irreplaceable role, especially in small-batch, decentralized construction.
[0003] However, the existing electric flatbed trolleys used in engineering construction mostly have a fixed platform area, and the width of their bearing surface and support range cannot be flexibly adjusted according to actual transportation needs. When multiple cement bags are placed side by side or stacked to improve transportation efficiency, some cement bags can easily extend beyond the edge of the platform. Lacking effective lateral support, and in addition, the uneven ground of the construction site, the bumps during the trolley's movement can easily cause the edge cement bags to slip due to unstable force. This not only causes damage and waste of cement bags, but may also cause construction workers to trip due to falling cement bags, and also reduces transportation efficiency. Utility Model Content
[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable cement transfer device for engineering construction. This device features flexible adjustment of the platform support area, providing stable support and anti-slip properties, and adaptability to different cement bag placement needs. It improves upon or solves the problem that existing electric flatbed trolleys used in engineering construction often have a fixed platform area, meaning the width and support range of the bearing surface cannot be flexibly adjusted according to actual transfer needs. When multiple cement bags are placed side-by-side or stacked to improve transfer efficiency, some bags easily extend beyond the platform edge, lacking effective lateral support. Furthermore, the uneven surface of construction sites and the bumps during trolley movement can cause edge cement bags to slip due to unstable force, resulting in not only damage and waste of cement bags but also tripping hazards for construction workers and reduced transfer efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cement transfer device for engineering construction, comprising a platform, a drive wheel assembly, a control wheel assembly, a battery pack, and a control handle. The drive wheel assembly is fixedly connected to the lower front end of the platform, the control wheel assembly is fixedly connected to the lower rear end of the platform, the battery pack is fixedly connected to the lower side of the platform, and the control handle is located on the rear side of the platform, with its lower end fixedly connected to the control wheel assembly. A cavity is provided inside the platform, and an adjustment device is provided inside the platform. The adjustment device includes an extension component, a movable support component, and a linkage control component.
[0006] In a preferred embodiment of this utility model, there are two expansion components, which are respectively disposed on the left and right sides of the upper part of the vehicle panel. There are four movable support components, which are respectively disposed below the front and rear ends of the expansion components on the left and right sides. The linkage control component is disposed at the lower part of the vehicle panel.
[0007] As a preferred embodiment of the present invention, the extension component includes an extension plate and a movable block. The extension plate is disposed on the right side of the upper end of the vehicle panel, and its right end extends out of the vehicle panel and is slidably connected to the vehicle panel. The movable block is fixedly connected to the lower surface of the left end of the extension plate.
[0008] As a preferred embodiment of this utility model, the extension plate extends from the upper surface of one end of the vehicle plate and is fixedly connected to a limit rail.
[0009] In a preferred embodiment of this invention, the movable support assembly includes a support beam, a movable support rod, and a support bracket. The support beam is fixedly connected to the right side of the lower surface of the vehicle panel. The movable support rod is disposed inside the support beam, with its right end extending out of the support beam and slidably connected to it. The support bracket is sleeved on the surface of the end of the movable support rod extending out of the support beam and is fixedly connected to the movable support rod. The upper side of the support bracket is fixedly connected to the lower surface of the extension plate extending out of the vehicle panel.
[0010] As a preferred embodiment of this utility model, the linkage control component includes a motor and screws. The motor is a bidirectional output motor, which is fixedly connected to the lower surface inside the vehicle panel. There are two screws, which are respectively fixedly connected to the left and right output ends of the motor. The ends of the two screws that are far apart from each other pass through the moving blocks on the left and right sides respectively, and are rotatably connected to the left and right sides inside the vehicle panel. The two screws are threadedly connected to the two moving blocks.
[0011] As a preferred embodiment of this utility model, the upper surface of the vehicle plate and the upper surfaces of the two extended plates are each uniformly provided with a plurality of anti-slip textures.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the coordinated use of a platform, drive wheel assembly, control wheel assembly, battery pack, control handle, adjustment device, extension component, extension plate, moving block, movable support component, support beam, movable support rod, support bracket, linkage control component, motor, screw, limit bar, and anti-slip texture, improves or solves to a certain extent the problem that the platform area of existing electric flatbed trolleys used in engineering construction is mostly a fixed structure, and the width of its bearing surface and support range cannot be flexibly adjusted according to actual transportation needs. When multiple cement bags are placed side by side or stacked to improve transportation efficiency, some cement bags can easily exceed the edge of the platform, lacking effective lateral support. In addition, the ground of the construction site is often uneven, and the bumps during the trolley's movement can easily cause the edge cement bags to slip due to unstable force, which not only causes damage and waste of cement bags, but may also cause construction workers to trip due to falling cement bags, and also reduces transportation efficiency.
[0014] 2. By setting up an extension component and a movable support component, this utility model not only achieves flexible expansion of the support area of the vehicle platform, but also provides stable support for the extended part. At the same time, the limit bar prevents the cement bag from slipping, which significantly improves the safety and applicability of transportation.

This utility model, by setting up a linkage control component, wherein the bidirectional output end motor synchronously drives the screws on both sides, realizes the symmetrical adjustment of the left and right extension plates, ensures the stability and accuracy of the support area adjustment, and improves the ease of operation.

[0025] Example 1
[0026] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an adjustable cement transfer device for engineering construction, including a vehicle platform 1, a drive wheel set 2, a control wheel set 3, a battery pack 4, and a control handle 5. The drive wheel set 2 is fixedly connected to the lower front side of the vehicle platform 1, the control wheel set 3 is fixedly connected to the lower rear side of the vehicle platform 1, the battery pack 4 is fixedly connected to the lower side of the vehicle platform 1, and the control handle 5 is located on the rear side of the vehicle platform 1, with its lower end fixedly connected to the control wheel set 3. A cavity is opened inside the vehicle platform 1, and an adjustment device 6 is provided inside the vehicle platform 1. The adjustment device 6 includes an extension component 7, a movable support component 8, and a linkage control component 9.
[0027] There are two extension components 7, which are respectively located on the left and right sides of the upper part of the vehicle plate 1. There are four movable support components 8, which are respectively located below the front and rear ends of the extension components 7 on the left and right sides. The linkage control component 9 is located at the lower part of the vehicle plate 1.
[0028] Specifically, the device uses the adjustment device 6 to flexibly adjust the support area on both sides of the vehicle platform 1, which can accommodate the placement needs of cement bags of different quantities and sizes, effectively preventing cement bags from slipping and improving the stability and efficiency of transportation.
[0029] Furthermore, the linkage control component 9 drives the extension component 7 to extend and retract along the cavity of the vehicle panel 1 to change the support area. The movable support component 8 moves synchronously with the extension component 7 to provide stable support. The three work together to complete the adjustment and stabilization of the support area.
[0030] Example 2
[0031] In the second embodiment of this utility model, the extension component 7 includes an extension plate 71 and a moving block 72. The extension plate 71 is disposed on the right side of the upper end of the vehicle plate 1, and the right end extends out of the vehicle plate 1 and is slidably connected to the vehicle plate 1. The moving block 72 is fixedly connected to the lower surface of the left end of the extension plate 71.
[0032] The extension plate 71 extends out of the upper surface of one end of the vehicle plate 1 and is fixedly connected to the limit rail 10;
[0033] The movable support assembly 8 includes a support beam 81, a movable support rod 82, and a support bracket 83. The support beam 81 is fixedly connected to the right side of the lower surface of the vehicle plate 1. The movable support rod 82 is disposed inside the support beam 81, and its right end extends out of the support beam 81 and is slidably connected to the support beam 81. The support bracket 83 is sleeved on the surface of the end of the movable support rod 82 that extends out of the support beam 81 and is fixedly connected to the movable support rod 82. The upper side of the support bracket 83 is fixedly connected to the lower surface of the extension plate 71 that extends out of the vehicle plate 1.
[0034] The upper surface of the vehicle plate 1 and the upper surfaces of the two extension plates 71 are each uniformly provided with a number of anti-slip textures 11.
[0035] Specifically, by setting the extension component 7 in conjunction with the movable support component 8, the support area of the vehicle platform 1 can be flexibly expanded, and stable support can be provided for the extended part. At the same time, the limit bar 10 prevents the cement bag from slipping, which significantly improves the safety and applicability of transportation.
[0036] Furthermore, the screw 92 is threadedly connected to the movable block 72 in the extension assembly 7, and the movable block 72 is fixed to the lower surface of the extension plate 71. Therefore, the rotation of the screw 92 is converted into the horizontal linear motion of the movable block 72. When it is necessary to increase the support area on both sides of the vehicle plate 1, the control motor 91 is rotated in the forward direction, and the two screws 92 respectively drive the movable blocks 72 on the left and right sides to move outward from the vehicle plate 1, thereby pushing the extension plate 71 to slide outward along the cavity inside the vehicle plate 1. The portion of the extension plate 71 extending out of the vehicle plate 1 gradually increases until it reaches the width suitable for placing cement bags. When the extension plate 71 extends outward, the support bracket 8 fixed on the lower surface of its extension end... 3 will cause the movable support rod 82 to slide along the inside of the support beam 81, so that the movable support rod 82 extends outward synchronously with the extension plate 71. The support beam 81 and the movable support rod 82 together form the bottom support structure for the extension plate 71, ensuring that the extension plate 71 remains stable when bearing the weight of the cement bag, and avoiding significant sinking due to force, which would affect its use. At the same time, the limiting rail 10 on the upper surface of the extension plate 71 extends synchronously with the extension plate 71, which can play a lateral blocking role for the cement bag placed on the extension plate 71, preventing it from slipping. Throughout the process, the anti-slip texture 11 on the upper surface of the vehicle plate 1 and the extension plate 71 can increase the friction between the cement bag and the bearing surface, further improving the placement stability.
[0037] Example 3
[0038] In the third embodiment of this utility model, the linkage control component 9 includes a motor 91 and screws 92. The motor 91 is a bidirectional output motor 91, which is fixedly connected to the lower surface of the vehicle plate 1. There are two screws 92, which are fixedly connected to the left and right output ends of the motor 91 respectively. The ends of the two screws 92 that are far apart from each other pass through the moving blocks 72 on the left and right sides respectively, and are rotatably connected to the left and right sides inside the vehicle plate 1. The two screws 92 are threadedly connected to the two moving blocks 72.
[0039] Specifically, by setting up a linkage control component 9, in which the bidirectional output motor 91 synchronously drives the screws 92 on both sides, the symmetrical adjustment of the left and right extension plates 71 is realized, ensuring the stability and accuracy of the support area adjustment and improving the ease of operation.
[0040] Furthermore, after the motor 91 starts, its output ends on the left and right sides will synchronously drive the two screws 92 to rotate. Since the screws 92 are threadedly connected to the moving block 72 in the extension component 7, and the moving block 72 is fixed on the lower surface of the extension plate 71, the rotation of the screws 92 will be converted into the horizontal linear motion of the moving block 72.
[0041] Working principle:
[0042] In use, the motor 91 can be started according to the number, size and placement requirements of the cement bags to be placed on the platform 1. After the motor 91 is started, the output ends on the left and right sides will synchronously drive the two screws 92 to rotate. Since the screws 92 are threadedly connected to the moving blocks 72 in the extension component 7, and the moving blocks 72 are fixed on the lower surface of the extension plate 71, the rotation of the screws 92 will be converted into the horizontal linear motion of the moving blocks 72. When it is necessary to increase the support area on both sides of the platform 1, the motor 91 is controlled to run in the forward direction. The two screws 92 drive the moving blocks 72 on the left and right sides to move outward from the platform 1, thereby pushing the extension plate 71 to slide outward along the cavity inside the platform 1. The part of the extension plate 71 extending out of the platform 1 gradually increases until it reaches the width suitable for placing cement bags.
[0043] During this process, when the extension plate 71 extends outward, the support bracket 83 fixed on the lower surface of its extension end will drive the movable support rod 82 to slide along the inside of the support beam 81, so that the movable support rod 82 extends outward synchronously with the extension plate 71. The support beam 81 and the movable support rod 82 together form the bottom support structure for the extension plate 71, ensuring that the extension plate 71 remains stable when bearing the weight of the cement bag, and avoiding significant sinking due to force, which would affect its use. At the same time, the limiting rail 10 on the upper surface of the extension plate 71 extends outward synchronously with the extension plate 71, which can play a lateral blocking role for the cement bag placed on the extension plate 71, preventing it from slipping.
[0044] If the support area needs to be reduced, the control motor 91 rotates in reverse, and the screw 92 drives the moving block 72 and the extension plate 71 to retract into the vehicle plate 1. The movable support rod 82 also retracts into the support beam 81 in sync with the support bracket 83 until the extension plate 71 returns to its initial position, thus completing the adjustment of the support area. Throughout the process, the anti-slip texture 11 on the upper surface of the vehicle plate 1 and the extension plate 71 can increase the friction between the cement bag and the bearing surface, further improving the placement stability. Through the linkage of the adjustment device 6, the function of flexibly adjusting the support area according to the placement requirements of the cement bag is realized.
[0045] In summary, by using the combined components of the vehicle platform 1, drive wheel assembly 2, control wheel assembly 3, battery pack 4, control handle 5, adjustment device 6, extension assembly 7, extension plate 71, moving block 72, movable support assembly 8, support beam 81, movable support rod 82, support bracket 83, linkage control component 9, motor 91, screw 92, limit bar 10, and anti-slip texture 11, the vehicle platform support area can be flexibly adjusted, providing stable support and anti-slip properties, and adapting to different cement bag placement needs.
