Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of concrete test block transportation, specifically a concrete test block transportation vehicle. Background Technology
[0002] Concrete test blocks, also known as cubic test blocks, are used to determine the compressive strength of concrete. In my country, cubic molds are used for concrete compressive strength testing. The compressive strength of concrete test blocks is a key indicator reflecting the quality of concrete construction in an engineering project, and the appropriateness of the test block preparation method and procedure is crucial. The basic method of transporting test blocks involves manually placing each concrete test block onto a small cart, and then using the cart to transfer multiple concrete test blocks from the production site to the laboratory. During transportation, the test blocks are prone to collisions with the holding structure due to external forces.
[0003] Chinese patent CN214689656U discloses a concrete test block transfer device, including a trolley. The trolley includes a body, a push rod fixedly connected to the body, casters installed at the bottom of the body, and multiple support plates fixedly connected to the body. A holding mechanism for holding concrete test blocks is detachably connected to the support plates. The holding mechanism includes an upper mold and a lower mold that cooperates with the upper mold. Both the upper mold and the lower mold are rectangular blocks and are connected by bolts. The lower mold has multiple first grooves for placing concrete test blocks.
[0004] In the above scheme, the holding mechanism consisting of an upper mold and a lower mold allows the concrete test blocks to be transported to the laboratory without having to be taken out and sorted one by one. However, this has the following disadvantages: although the concrete test blocks can be confined within the holding mechanism consisting of the upper mold and the lower mold, the lack of a limiting structure within the holding mechanism makes it easy for the concrete test blocks to shake and collide within the holding mechanism due to external forces during the transfer process. Utility Model Content
[0005] The purpose of this utility model is to provide a concrete test block transport vehicle to solve the problem that although the concrete test block can be confined in the holding mechanism composed of the upper and lower molds, the holding mechanism does not have a limiting structure, which makes the concrete test block easily shake and collide in the holding mechanism due to external forces during the transport process.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a concrete test block transport vehicle, comprising several placement seats, all of which are slidably disposed on the inner wall of a housing. The bottom surface of the housing is fixed with a transport vehicle body. Several placement slots are formed on the top surface of each placement seat. A receiving slot is formed on the right side of the inner wall of each placement slot. A limiting rod is inserted into the inner wall of the receiving slot. A limiting plate is fixed to the left end of the limiting rod. The limiting plate is slidably connected to the placement slot. Several sliding holes are formed on the top surface of each placement seat. The sliding holes are connected to the receiving slot. A fixing bolt is inserted into the inner wall of each sliding hole. The threaded end of the fixing bolt is threadedly connected to the top surface of the limiting rod. Several positioning slots are formed on both the front and rear sides of the inner wall of each placement slot. The several positioning slots are interconnected. A positioning plate is inserted into the inner wall of each positioning slot.
[0007] Preferably, the top surface of the placement base has a plurality of scale lines, the scale lines corresponding to the positioning groove, and the top surface of the positioning plate has two pointers fixed thereto, the pointers corresponding to the scale lines.
[0008] Preferably, protective pads are fixed to both the left side of the inner wall of the placement groove and the limiting plate.
[0009] Preferably, a connecting groove is provided on the rear side of the placement seat, the connecting groove is connected to the placement groove, a collection box is slidably connected to the inner wall of the connecting groove, and an L-shaped block is fixed on the collection box.
[0010] Preferably, the inner wall of the housing has several mounting grooves on both the left and right sides, and the inner wall of the mounting groove is fixed with a slide rail, the slider of the slide rail being fixed to the placement seat.
[0011] Preferably, the housing has a plurality of sliding grooves, and the inner wall of the sliding groove is slidably connected to a limiting frame, which is engaged with the inner wall of the L-shaped block.
[0012] Compared with the prior art, the present invention has the following beneficial effects: I. Through the coordinated action of the placement seat, limiting rod, limiting plate, fixing bolts, and positioning plate, multi-directional limiting and fixing of concrete test blocks can be achieved, allowing the concrete test blocks to be stably placed in the placement groove. This effectively prevents the concrete test blocks from being impacted and vibrated by external forces during transportation, avoiding shaking, shifting, and collision within the placement groove, and reducing the risk of edge and corner damage. This not only significantly improves the structural stability and operational safety of the transport vehicle during transportation operations but also ensures the accuracy of subsequent test results. The coordinated action of the scale lines and the indicator allows operators to quickly determine the position of the positioning plate by using the scale value corresponding to the indicator, accurately adjusting the limiting distance in the front and rear directions of the test block. This is especially suitable for test blocks with small size differences, avoiding limiting failure due to adjustment errors. Second, the protective pads prevent direct rigid contact between the test blocks and the rigid material placement slots and limiting plates, buffering the impact force during transport vibrations or limit adjustments, reducing damage to the edges and corners of the test blocks, and ensuring the accuracy of the test data. The collection box allows for the centralized collection of fragments generated after testing, preventing fragments from scattering inside the equipment or on the ground, maintaining a clean operating environment, allowing intact test blocks to remain in the placement slots while fragments are collected separately, achieving classified storage of intact and fragmented test blocks. Third, the sliding rail provides a stable track for the placement seat, allowing it to move laterally along the rail. This facilitates pushing the test block assembly to the front position near the inspector, and after testing, it is moved to the rear storage area. This eliminates the need for the inspector to get up and move the blocks, significantly improving testing efficiency. The sliding groove and the limiting frame work together to secure the placement seat and collection box of the placed concrete test blocks, effectively preventing them from accidentally detaching during transport vehicle movement. This avoids test blocks falling and fragments spilling, thus improving the overall safety and stability of the transport vehicle. Attached Figure Description

[0018] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0019] like Figures 1-4As shown, a concrete test block transport vehicle includes several placement seats 1, each of which is slidably disposed on the inner wall of a housing 2. A transport vehicle body 201 is fixed to the bottom surface of the housing 2. Several placement grooves 3 are formed on the top surface of each placement seat 1. A receiving groove 4 is formed on the right side of the inner wall of each placement groove 3. A limiting rod 5 is inserted into the inner wall of the receiving groove 4. A limiting plate 6 is fixed to the left end of the limiting rod 5 and slidably connected to the placement groove 3. Several sliding holes 7 are formed on the top surface of each placement seat 1. Hole 7 is connected to receiving groove 4. A fixing bolt 8 is inserted into the inner wall of sliding hole 7. The threaded end of fixing bolt 8 is threaded to the top surface of limiting rod 5. Several positioning grooves 9 are opened on the front and rear sides of the inner wall of placement groove 3. The several positioning grooves 9 are interconnected. A positioning plate 10 is inserted into the inner wall of positioning groove 9. Several scale lines 11 are opened on the top surface of placement seat 1. The scale lines 11 correspond to the positioning grooves 9. Two pointers 12 are fixed on the top surface of positioning plate 10. The pointers 12 correspond to the scale lines 11.
[0020] When it is necessary to transfer concrete test blocks during use, the operator first adjusts the limiting frame 20 and pushes the two limiting frames 20 to move apart along the center line of the shell 2 in the sliding groove 19 to release their locking and limiting of the placement seat 1 and the collection box 15. After the limiting is released, the placement seat 1 is pulled out along the slide rail 18 on the inner wall of the shell 2 through the groove structure on the surface of the placement seat 1 to prepare for the loading of the test block. Subsequently, according to the width specifications of the concrete test block to be transported, the corresponding positioning groove 9 is selected, and two positioning plates 10 are inserted into the groove to make the spacing between the positioning plates 10 precisely match the width of the test block, thereby achieving the pre-positioning of the left and right sides of the test block. After the width adjustment is completed, the limiting plate 6 in the placement groove 3 is slid until both ends of the test block form a stable fit with the protective pad 13 on the left side of the inner wall of the placement groove 3 and the surface of the limiting plate 6, respectively. After the position of the limiting plate 6 is calibrated, the fixing bolt 8 in the sliding hole 7 is tightened. The pre-tightening force of the fixing bolt 8 is used to rigidly lock the limiting rod 5, thereby achieving the position fixation of the limiting plate 6 and completing the multi-directional limiting of the test block. When the concrete test blocks to be tested are placed steadily into the placement groove 3 that has been adjusted for limiting position, after loading is completed, push the placement seat 1 to slide along the slide rail 18, so that the placement seat 1 moves the test block into the shell 2 for temporary storage. Then, adjust the two limiting frames 20 in the opposite direction, so that they move towards each other along the center line of the shell 2 in the sliding groove 19 until the limiting frame 20 forms a reliable engagement with the inner wall of the L-shaped block 16, so as to achieve double limiting and fixing of the placement seat 1 and the collection box 15. Finally, the operator holds the handlebar of the transfer vehicle and pushes the transfer vehicle body 201 to smoothly transfer the equipment to the designated testing area through the bottom walking mechanism; Through the coordinated action of the placement seat 1, limiting rod 5, limiting plate 6, fixing bolt 8, and positioning plate 10, multi-directional limiting and fixing of the concrete test block can be achieved, allowing the concrete test block to be stably placed in the placement groove 3. This effectively prevents the concrete test block from being impacted and vibrated by external forces during transportation, avoiding shaking, shifting, and collision within the placement groove 3, and reducing the risk of damage to the test block's edges and corners. This not only significantly improves the structural stability and operational safety of the transport vehicle body 201 during transportation operations but also ensures the accuracy of subsequent test results. Through the coordinated action of the scale line 11 and the indicator 12, operators can quickly determine the position of the positioning plate 10 by using the scale value corresponding to the indicator 12, and accurately adjust the limiting distance in the front and rear directions of the test block. This is especially suitable for test blocks with small size differences, avoiding limiting failure due to adjustment errors.
[0021] like Figures 1-4 As shown, protective pads 13 are fixed on the left side of the inner wall of the placement groove 3 and on the limiting plate 6. A connecting groove 14 is provided on the rear side of the placement seat 1. The connecting groove 14 is connected to the placement groove 3. A collection box 15 is slidably connected to the inner wall of the connecting groove 14. An L-shaped block 16 is fixed on the collection box 15. Several mounting grooves 17 are provided on both the left and right sides of the inner wall of the housing 2. A slide rail 18 is fixed to the inner wall of the mounting groove 17. The slider of the slide rail 18 is fixed to the placement seat 1. Several sliding grooves 19 are provided on the housing 2. A limiting frame 20 is slidably connected to the inner wall of the sliding groove 19. The limiting frame 20 is snapped into the inner wall of the L-shaped block 16.
[0022] During use, the protective pad 13 prevents the test block from directly and rigidly contacting the rigid material placement groove 3 and the limiting plate 6. It buffers the impact force during transport vibration or limit adjustment, reduces the damage to the edges and corners of the test block, and ensures the accuracy of the test block test data. The collection box 15 can collect the fragments generated by the test block after testing, preventing fragments from scattering inside the equipment or on the ground, keeping the operating environment clean, allowing intact test blocks to remain in the placement groove 3, and fragments to be collected separately, achieving classified storage of intact test blocks and fragments. The slide rail 18 provides a stable sliding track for the placement seat 1, allowing it to move laterally along the slide rail 18. This facilitates pushing the test block group to the front position near the inspector, and after testing, it is moved to the rear storage area without requiring the inspector to get up and move it, greatly improving testing efficiency. Through the coordinated action of the sliding groove 19 and the limiting frame 20, the placement seat 1 and collection box 15 with the concrete test blocks placed on them can be limited and fixed, effectively preventing the placement seat 1 or collection box 15 from accidentally falling off when the transport vehicle body 201 moves, avoiding test blocks falling and fragments spilling, thereby improving the overall safety and stability of the transport vehicle body 201.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
