Description

Technical Field

[0001] The utility model relates to the technical field of concrete test block curing, in particular to a storage rack for placing concrete blocks. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates, water and admixtures added when necessary in a certain proportion, which is then evenly mixed, compacted into a dense shape, and cured and hardened. When using concrete for construction, it is necessary to make concrete test blocks for testing. Concrete test blocks are an important tool for testing whether the compressive strength of concrete meets the requirements. According to the requirements of the quality acceptance code for concrete structure engineering, a certain number of test blocks need to be left for each batch of concrete pouring, and sent to the curing room for a period of curing before testing. The prepared concrete test blocks are sent to the curing room for testing. During curing, it needs to be placed on a special rack. Existing racks for placing concrete blocks are mostly composed of a frame body and a rack plate. The rack plates are fixed to the inside of the frame body in sequence by bolts, and then the concrete test blocks are placed on the rack plates in sequence for curing. Since the concrete test blocks are made of aggregate and water, the weight of the test blocks is relatively large. The position of the rack plates of traditional racks for placing concrete blocks is fixed. When placing and taking concrete test blocks on the high rack plates, it is often difficult to place and take them in easily due to the weight of the test blocks. It is necessary to use high stools and ladders to assist in the placement of the concrete test blocks, which puts a heavy labor burden. For this reason, we propose a rack for placing concrete blocks.

The single-chip microcomputer controls the telescopic ends of the two electric push rods to move upward, lifting the movable plate. The pressure of the concrete block weight disappears, and the locking frame leaves the bottom wall of the locking groove. Once the spring is no longer under force, it rebounds, driving the two locking frames to move inward synchronously. The locking frame is retracted into the movable plate. The movable plate is no longer restricted and can be quickly raised and lowered, making it easier to take and place concrete blocks.

[0023] Moving mechanism 4: It includes a locking frame 41, a first spring 42, a cam 43 and a locking groove 44. The locking frames 41 are respectively slidably connected to the front and rear sides inside the moving plate 2. The locking frame 41 is a U-shaped frame. A first spring 42 is provided between the middle of the outer sides facing away from each other of two longitudinally adjacent locking frames 41 and the inner wall of the moving plate 2. The cams 43 are respectively rotatably connected to the lower end of the center inside the moving plate 2. The opposite inner sides of two longitudinally adjacent locking frames 41 are respectively fitted and installed with the outer edges of the cams 43. The locking grooves 44 are respectively opened on the front and rear side walls of the frame 1. The locking frames 41 on the same side are fitted and installed with the locking grooves 44, providing a basis for the fixation of the moving plate 2. The height of the locking groove 44 is greater than the thickness of the locking frame 41, facilitating the upward movement of the locking frame 41. The moving mechanism 4 further includes a moving component 45. The moving component 45 further includes sliding columns 451, a support plate 452 and a second spring 453. Installation grooves 3 are respectively opened in the middle of the left and right sides inside the moving plate 2. The sliding columns 451 are respectively slidably connected to the inside of the installation grooves 3. The support plates 452 are respectively arranged at the outer ends of the sliding columns 451. The inner ends of the sliding columns 451 are respectively fitted and installed with the outer edges of the laterally adjacent cams 43. A second spring 453 is provided between the middle of each sliding column 451 and the inner wall of the installation groove 3. The second springs 453 are respectively sleeved on the outer surfaces of the sliding columns 451, providing a basis for the retraction and extension of the support plate 452. The moving mechanism 4 further includes a worm 46 and a worm gear 47. The worms 46 are respectively rotatably connected to the middle of the upper end inside the moving plate 2. The worm gears 47 are respectively arranged at the upper ends of the cams 43. The laterally adjacent worms 46 and worm gears 47 are meshed and connected, providing a basis for the rotation of the cams 43. It further includes a handwheel 5. The handwheels 5 are respectively arranged at the front ends of the worms 46, providing drive for the rotation of the cams 43. The moving mechanism 4 further includes electric push rods 48. The electric push rods 48 are respectively arranged at the middle of the left and right sides at the upper end of the frame 1. The input ends of the electric push rods 48 are electrically connected to the output ends of the single-chip microcomputer 6. The upper ends of the telescopic ends of the electric push rods 48 are respectively fitted and installed with the lower ends of the vertically adjacent support plates 452, providing stable drive for the movement of the moving plate 2. There is a movable support plate, which can quickly raise and lower the support plate and firmly fix the support plate, enabling the picking and placing of concrete blocks at a low position and reducing the burden of manual picking and placing.

[0024] The working principle of a storage rack for placing concrete blocks provided by the present invention is as follows: when placing concrete blocks, the concrete blocks are first placed on the upper end of the uppermost movable plate 2 in sequence, and the single-chip microcomputer 6 controls the two electric push rods 48 to work. The telescopic ends of the two electric push rods 48 move upward at the same time until the telescopic ends of the electric push rods 48 are close to the lower end of the supporting plate 452 inside the uppermost movable plate 2. At this time, the handwheel 5 in front of the uppermost movable plate 2 is rotated forward, driving the worm 46 to rotate, and the worm gear 47 also rotates synchronously, driving the cam 43 to rotate accordingly. As the cam 43 rotates, the protruding part of the cam 43 squeezes the inner end of the sliding column 451, and the sliding column 451 moves outward accordingly, and the supporting plate 452 also moves outward synchronously. The spring two 453 is compressed by force until the cam 43 rotates ninety degrees. At this time, the outer side of the support plate 452 extends out of the movable plate 2. The support plate 452 is vertically adjacent to the telescopic end of the electric push rod 48. The cam 43 loses the squeezing effect on the relative inner sides of the two locking frames 41. Due to the pressure of the weight of the concrete block, the lower end of the locking frame 41 is still close to the bottom wall of the initial locking groove 44. The two locking frames 41 will not retract inward. The single-chip microcomputer 6 controls the two electric push rods 48 to work. The telescopic ends of the two electric push rods 48 move up to a certain height at the same time. As the telescopic ends of the electric push rods 48 move up, the telescopic ends of the electric push rods 48 contact the support plate 452 and lift the support plate 452, and the movable plate 2 also moves up accordingly. As the movable plate 2 moves upward, the lower end of the locking frame 41 leaves the bottom wall of the locking groove 44, and the spring 1 42 rebounds without force, driving the two locking frames 41 to move inward synchronously, and the locking frames 41 are retracted into the inside of the movable plate 2. At this time, the telescopic end of the electric push rod 48 continues to move upward until the locking frames 41 are aligned with the corresponding locking groove 44, and the hand wheel 5 is reversed, driving the worm gear 47 and the cam 43 to rotate synchronously until the cam 43 returns to its original position. The protruding part of the cam 43 squeezes the relative inner side surfaces of the two locking frames 41, so that the two locking frames 41 move outward synchronously and insert into the corresponding locking groove 44. The cam 43 loses the squeezing effect on the inner ends of the two sliding posts 451. Due to the pressure of the weight of the concrete block, the support plate 452 is close to the electric push rod 48. The upper end of the telescopic end of the push rod 48 will not be retracted. At this time, the single-chip microcomputer 6 controls the telescopic ends of the two electric push rods 48 to move down to their original positions. After the telescopic end of the electric push rod 48 leaves the support plate 452, the locking frame 41 is pressed against the bottom wall of the locking groove 44 due to gravity. The spring 2 453 rebounds without force and drives the sliding column 451 and the support plate 452 back to their original positions. The support plate 452 returns to the inside of the movable plate 2, and then the concrete block is placed on the next movable plate 2 and starts to move, and so on and so forth until all the movable plates 2 are moved to the appropriate position. After the maintenance is completed, it is only necessary to move the movable plates 2 in sequence from bottom to top, so that all the movable plates 2 can be quickly moved to the bottom of the frame 1, which is convenient for taking and placing concrete blocks.

[0025] It is worth noting that the single chip microcomputer 6 disclosed in the above embodiment is an S7-200 single chip microcomputer, the electric push rod 48 is a LAP56 electric push rod, and the single chip microcomputer 6 controls the operation of the electric push rod 48 using a method commonly used in the prior art.
