Description

Technical Field

[0001] This utility model belongs to the field of building concrete construction technology, and in particular relates to a concrete lifting and feeding machine for building concrete construction. Background Technology

[0002] Concrete construction is a crucial part of building projects, involving mixing cement, sand, gravel, and water in specific proportions to create concrete, and then forming a solid structure through steps such as pouring, vibration, and curing. This process is essential to ensuring the strength and durability of buildings. In modern construction, especially high-rise building construction, concrete lifting and loading machines play an important role. This equipment is mainly used to solve the problem of vertical transportation of concrete. It can efficiently and safely lift concrete from the ground or a lower position to the required height, overcoming the shortcomings of traditional manual handling, such as low efficiency and high labor intensity, greatly improving construction efficiency and safety, while adapting to the needs of various complex construction sites.

[0003] The problem with existing technology is that existing equipment generally has a fixed bottom structure that cannot be expanded or retracted, resulting in a large space occupation during placement or transportation, affecting the reasonable layout and traffic efficiency of the construction site. Especially when facing narrow spaces or multi-story operations, it is difficult to flexibly arrange the equipment, which limits its applicability and ease of use, while also increasing the difficulty of handling and storage. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a concrete lifting and feeding machine for building concrete construction. It has the advantages of an expandable and retractable bottom structure, which solves the problem that the bottom structure of existing equipment is fixed and cannot be expanded or retracted. This results in a large space occupation during placement or transportation, affecting the reasonable layout and traffic efficiency of the construction site. Especially when facing narrow spaces or multi-story operations, it is difficult to flexibly arrange the equipment, which limits its applicability and ease of use, and also increases the difficulty of handling and storage.

[0005] This utility model is implemented as follows: a concrete lifting and feeding machine for building concrete construction includes a mobile frame and a lifting and feeding machine body. The lifting and feeding machine body is fixedly connected to the top of the mobile frame. Universal wheels are fixedly connected to the four corners of the bottom of the mobile frame. A control cabinet is fixedly connected to the right side of the lifting and feeding machine body. Extension frames are placed on the front and rear sides of the mobile frame body. The sides of the extension frames that are close to each other are slidably connected to the inside of the mobile frame.

[0006] In a preferred embodiment of this invention, receiving blocks are fixedly connected to both the front and rear sides of the top of the movable frame. Each receiving block has a receiving groove inside. Springs are fixedly connected to the left and right sides of the top of each receiving groove. A movable plate is placed inside each receiving groove. The bottom of each spring is fixedly connected to the top of the movable plate. A fixing rod is fixedly connected to the bottom of each movable plate. The bottom of each fixing rod penetrates through and extends out of the bottom of the receiving block. A number of fixing holes are equidistantly opened on the top of the extension frame. The fixing holes cooperate with the fixing rods. By setting the fixing rods and fixing holes, the extension frame can be quickly positioned and securely locked, improving the safety and ease of operation of the equipment.

[0007] As a preferred embodiment of this utility model, stabilizing rods are placed on both the left and right sides inside the receiving groove. The upper and lower ends of the stabilizing rods are fixedly connected to the surface of the receiving groove. The positions of the stabilizing rods correspond to the positions of the springs. The left and right sides of the moving plate are slidably connected to the surface of the stabilizing rods. By setting stabilizing rods, the guiding and stability of the moving plate during the lifting process can be enhanced, preventing it from deviating or getting stuck, thereby improving the smoothness of the overall operation.

[0008] As a preferred embodiment of this utility model, extension plates are placed on both the left and right sides inside the extension frame. The extension plates are slidably connected to the inside of the extension frame. A sliding groove is provided on the top of the extension frame. Slider blocks are placed on both the left and right sides inside the sliding groove. The slider blocks are slidably connected to the inside of the sliding groove. The bottom of the slider blocks is fixedly connected to the top of the extension plate. By setting the extension plates, the width of the extension frame can be flexibly adjusted, which is convenient for expanding the bottom support area according to actual construction needs, while ensuring the smooth movement and accurate positioning of the extension plates during the adjustment process.

[0009] In a preferred embodiment of this invention, the top of each slider is fixedly connected to a limiting frame, and each limiting frame contains a limiting rod. The limiting frame is slidably connected to the inside of the limiting frame. The top of the extension frame is provided with a number of limiting holes at equal intervals. Each limiting hole cooperates with the limiting rod. By setting the limiting rod and the limiting hole, the position of the extension plate can be stably locked, preventing unnecessary movement during use, thereby improving the stability and safety of the overall structure of the equipment.

[0010] As a preferred embodiment of this utility model, connecting blocks are fixedly connected to the left and right sides of the extension frame and the side of the extension plate that is far apart from each other. A lead screw is placed at the bottom of each connecting block. The lead screw is threaded to the surface of the connecting block. A fixing plate is fixedly connected to the bottom of each lead screw. By setting the lead screw and the fixing plate, adjustable auxiliary support can be provided for the extended parts of the extension frame and the extension plate, thereby enhancing the stability of the equipment on complex terrain or uneven ground.

[0011] As a preferred embodiment of this utility model, each of the movable plates is fixedly connected to a pull rod at its top. The top of each pull rod extends through and out of the top of the receiving block. By setting the pull rod, the operator can conveniently and quickly adjust the position of the movable plate, thereby realizing the rapid unlocking and repositioning of the extension frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, the concrete lifting and feeding machine for building concrete construction provided by this utility model embodiment includes a mobile frame 1 and a lifting and feeding machine body 2. The lifting and feeding machine body 2 is fixedly connected to the top of the mobile frame 1. Universal wheels 3 are fixedly connected to the four corners of the bottom of the mobile frame 1. A control cabinet 5 is fixedly connected to the right side of the lifting and feeding machine body 2. Extension frames 4 are placed on the front and rear sides of the mobile frame 1 body. The sides of the extension frames 4 that are close to each other are slidably connected to the inside of the mobile frame 1.

[0023] refer to Figure 3 and Figure 4 The top front and rear sides of the movable frame 1 are fixedly connected to receiving blocks 6. Receiving slots 7 are opened inside the receiving blocks 6. Springs 8 are fixedly connected to the top left and right sides of the receiving slots 7. Moving plates 9 are placed inside the receiving slots 7. The bottom of the springs 8 is fixedly connected to the top of the moving plates 9. The bottom of the moving plates 9 is fixedly connected to the fixing rods 10. The bottom of the fixing rods 10 passes through and extends out of the bottom of the receiving blocks 6. A number of fixing holes 11 are opened at equal intervals on the top of the extension frame 4. The fixing holes 11 are used in conjunction with the fixing rods 10.

[0024] By adopting the above solution, the extension frame 4 can be quickly positioned and securely locked by setting the fixing rod 10 and fixing hole 11, thereby improving the safety and ease of operation of the equipment.

[0025] refer to Figure 4 Stabilizing rods 12 are placed on both the left and right sides inside the receiving groove 7. The upper and lower ends of the stabilizing rods 12 are fixedly connected to the surface of the receiving groove 7. The positions of the stabilizing rods 12 correspond to the positions of the springs 8. The left and right sides of the moving plate 9 are slidably connected to the surface of the stabilizing rods 12.

[0026] By adopting the above solution, the stability of the moving plate 9 during the lifting and lowering process can be enhanced by setting the stabilizing rod 12, preventing it from deviating or getting stuck, thereby improving the smoothness of the overall operation.

[0027] refer to Figure 2 and Figure 3Extension plates 13 are placed on both the left and right sides inside the extension frame 4. The extension plates 13 are slidably connected to the inside of the extension frame 4. A slide groove 14 is provided on the top of the extension frame 4. Slider 15 is placed on both the left and right sides inside the slide groove 14. The slider 15 is slidably connected to the inside of the slide groove 14. The bottom of the slider 15 is fixedly connected to the top of the extension plate 13.

[0028] By adopting the above solution, the width of the extension frame 4 can be flexibly adjusted by setting the extension plate 13, which facilitates the expansion of the bottom support area according to actual construction needs, while ensuring the smooth movement and accurate positioning of the extension plate 13 during the adjustment process.

[0029] refer to Figure 3 Each slider 15 is fixedly connected to a limit frame 16 at its top. Each limit frame 16 has a limit rod 17 placed inside it. Each limit frame 16 is slidably connected to the inside of the limit frame 16. The top of the extension frame 4 is provided with a number of limit holes 18 at equal intervals. Each limit hole 18 is used in conjunction with the limit rod 17.

[0030] By adopting the above solution, the position of the extension plate 13 can be securely locked by setting the limiting rod 17 and the limiting hole 18, preventing unnecessary movement during use, thereby improving the stability and safety of the overall structure of the equipment.

[0031] refer to Figure 2 Connecting blocks 19 are fixedly connected to the left and right sides of the extension frame 4 and the side of the extension plate 13 that is far away from each other. A lead screw 20 is placed at the bottom of each connecting block 19. The lead screw 20 is threaded to the surface of the connecting block 19. A fixing plate 21 is fixedly connected to the bottom of each lead screw 20.

[0032] By adopting the above solution, by setting the lead screw 20 and the fixing plate 21, adjustable auxiliary support can be provided for the extended parts of the extension frame 4 and the extension plate 13, thereby enhancing the stability of the equipment on complex terrain or uneven ground.

[0033] refer to Figure 4 Each of the movable plates 9 is fixedly connected to a pull rod 22, and the top of the pull rod 22 extends through and out of the top of the receiving block 6.

[0034] By adopting the above solution, the operator can easily and quickly adjust the position of the moving plate 9 by setting the pull rod 22, thereby realizing the rapid unlocking and repositioning of the extension frame 4.

[0035] The working principle of this utility model:

[0036] In use, first move the device to a suitable working location, then fix the casters 3. Next, use the pull rod 22 to pull the moving plate 9 upwards. The moving plate 9 drives the fixing rod 10 upwards. When the fixing rod 10 moves out of the fixing hole 11, the fixing state of the extension frame 4 is released. Then pull the extension frame 4 out of the moving frame 1 and move it to a suitable position. Release the pull rod 22. At this time, the spring 8 returns to its original position, causing the fixing rod 10 to insert into the corresponding fixing hole 11, thereby fixing the extension frame 4. Adjust the extension frame 4. After completion, rotate the limiting rod 17. When the limiting rod 17 rotates to a certain angle, it moves out of the limiting hole 18. Then, move the slider 15 along the slide groove 14. The slider 15 drives the extension plate 13 to move. When the extension plate 13 moves to the appropriate position, the limiting rod 17 is inserted into the corresponding limiting hole 18. Then rotate the limiting rod 17 to prevent it from resetting. After the extension plate 13 is adjusted, rotate the lead screw 20 to make the fixing plate 21 contact the ground to increase the overall stability of the equipment.

[0037] In summary, the concrete lifting and feeding machine for building concrete construction, through the coordinated use of a movable frame 1, lifting and feeding machine body 2, casters 3, extension frame 4, control cabinet 5, receiving block 6, receiving groove 7, spring 8, moving plate 9, fixing rod 10, fixing hole 11, stabilizing rod 12, extension plate 13, slide 14, slider 15, limiting frame 16, limiting rod 17, limiting hole 18, connecting block 19, screw 20, fixing plate 21, and tie rod 22, solves the common problem of existing equipment having a fixed bottom structure and being unable to expand or contract. This results in a large space occupation during placement or transportation, affecting the reasonable layout and traffic efficiency of the construction site. Especially when facing narrow spaces or multi-story operations, it is difficult to flexibly arrange the equipment, limiting its applicability and ease of use, while also increasing the difficulty of handling and storage.
