Description

Technical Field

[0001] The utility model belongs to the technical field of concrete curing, and in particular relates to a concrete test block curing device. Background Art

[0002] Concrete test blocks are made of concrete in a certain proportion and prepared into standard parts of specified size and weight. Their performance determines the performance of concrete engineering to a certain extent. When preparing concrete test blocks, appropriate temperature and humidity are provided for the concrete test blocks through maintenance, thereby promoting the hydration reaction of cement-based materials, reducing the occurrence of cracks, and ensuring the performance of concrete test blocks.

[0003] A Chinese patent with publication number CN220094959U discloses a concrete test block curing device, including a plurality of drainage mechanisms, which are fixed at intervals in a box body, and are all used to drain condensed water generated in a humid environment during the curing process. The limit rods on both sides of the concrete test block are used to prevent the concrete test block from rolling. The limit rods are moved by the movable block and the limit rods, so that the limit rods fit the concrete test block. The bottom of the concrete test block is engaged by the placement groove, and the condensed water droplets on the placement plate are guided into the through groove through the inclined groove and fall into the bottom of the box body, so as to prevent the surface of the concrete test block from absorbing condensed water.

[0004] However, in actual use, since concrete test blocks have various sizes and shapes, and the limit rods in the above scheme can only move up and down, the wider square concrete test blocks cannot be placed between the limit rods, and the narrower concrete test blocks cannot be limited by the limit rods. In summary, the scope of application of the above scheme is narrow, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a concrete test block curing device to solve the problem of narrow application scope of the prior art mentioned above.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete test block curing device, comprising

[0007] The box body has a moisturizing cavity and a moisturizing mechanism inside, and a box door corresponding to the moisturizing cavity is installed outside the box body;

[0008] A plurality of placement plates are arranged at intervals along the height direction of the moisturizing chamber, and the top edge of the placement plate close to the box door is lower than the top edge of the placement plate away from the box door;

[0009] The maintenance mechanism is arranged in multiple intervals along the length direction of the placement plate. The maintenance mechanism includes a limit unit and two symmetrically arranged clamping components. The clamping components include a clamping plate, a connecting plate, a connecting rod, a limit block and a spring. The connecting plate is installed on the placement plate. The connecting rod is slidably inserted into the connecting plate, and one end of the connecting rod is fixed to the clamping plate, and the other end of the connecting rod is fixed to the limit block. The spring is sleeved on the connecting rod and is located on the side of the connecting plate away from the limit block. The limit unit is movably installed on the placement plate and is used to limit the sliding of the concrete test block relative to the placement plate.

[0010] The principle and effect of this technical solution:

[0011] 1. Through the arrangement of the placement plate, the moisturizing mechanism, the moisturizing chamber and the box door, the concrete test block placed in the device can obtain a specific curing humidity, and the curing mechanism includes a limit unit and two clamping components, so that when the concrete test block is placed on the placement plate, it can be restricted by the limit unit and not slip off the placement plate, and the clamping of the clamping component can play a centering function, so that the concrete test block can maintain a stable position.

[0012] 2. By tilting the placement plate and using the limit unit, the condensed water droplets can flow spontaneously, so that they are not easily accumulated on the concrete test block and excessively absorbed by the concrete test block, and the concrete test block will not fall off the placement plate.

[0013] 3. Through the setting of the clamping assembly, the distance between the clamping plate and the connecting plate can be adjusted by the compression spring, and the coordinated use of the connecting rod and the limit block can guide and limit the movement of the clamping plate, so that when round or square concrete test blocks of different sizes are placed on the placement plate, the clamping plate can be abutted against the outer surface of the concrete test blocks of different sizes by changing the compression amount of the spring to adapt to concrete test blocks of different sizes, thereby expanding the scope of application, and the round or square concrete test blocks can be restricted by the abutment of the clamping plate, and the setting of the two clamping assemblies can achieve a centering effect.

[0014] The utility model is further configured as follows: the limit unit includes two symmetrically arranged limit components, the limit components include a limit rod, a slider and a limit bolt, a placement plate is provided with a slide groove with a "T"-shaped cross-section, the limit rod is slidably inserted in the slide groove, the limit bolt is threadedly inserted in the bottom of the limit rod, and the head of the limit bolt is abutted against the bottom of the placement plate, the slider is fixed on the limit rod, and the slider is slidably fitted in the slide groove.

[0015] The principle and effect of this technical solution: through the setting of the slider, the limit bolt and the slide groove, the limit rod can slide along the slide groove, and the limit rod can also be restricted by the cooperation between the slider and the slide groove, and the abutment between the head of the limit bolt and the bottom of the placement plate, so that the limit rod has a good anti-roll capability, can abut against the side wall of the concrete test block, thereby preventing the concrete test block and the placement plate from sliding out on the side close to the box door, and the limit bolt can be turned to separate the limit rod from the placement plate, which is convenient for subsequent maintenance and replacement, and the position of the limit rod is adjusted by sliding the limit rod, so that the limit rod will not hinder the placement and removal of the concrete test block.

[0016] The utility model is further configured as follows: the limiting component also includes a plurality of support plates arranged at intervals along the placement plate, and the support plates are located on a side of the slide groove away from the box door.

[0017] The principle and effect of the technical solution: the contact area between the bottom of the concrete test block and the flat surface can be reduced by setting the support plate, so that the bottom of the concrete is not easy to hide water, and the water droplets are easy to drain. The round concrete test block can also be clamped by the edges of the two support plates, so that the round concrete test block is not easy to roll when placed on the placement plate.

[0018] The utility model is further configured as follows: the maintenance mechanism also includes a control component, the clamping component also includes a transmission shaft and a transmission plate, the transmission shaft is fixed to the bottom of the connecting plate, a transmission groove is opened on the placement plate, the transmission shaft is slidably inserted in the transmission groove, the bottom of the transmission shaft extends to the bottom of the placement plate, and is hinged to one end of the transmission plate, the control component is installed at the bottom of the placement plate, and is used to drive the other end of the transmission plate to move relative to the placement plate.

[0019] The principle and effect of the technical solution are as follows: through the arrangement of the transmission shaft, the transmission plate, the transmission groove and the control component, the control component drives the movement of the transmission plate and the transmission shaft to indirectly move the connecting plate, thereby playing the role of adjusting the position of the connecting plate. By adjusting the position of the connecting plate, when the clamping plate clamps the concrete test block, the connecting plate can be moved according to the specific size of the concrete test block, so that after the clamping plate is pressed against the concrete test block, the compression amount of the spring will not be too small or too large, so that concrete test blocks of different sizes can all be subjected to reasonable clamping compression force, thereby not damaging the concrete test block and playing the centering function.

[0020] The utility model is further configured as follows: the control component includes a control cap, a control screw and a control block, the control screw is rotatably installed on the bottom of the placement plate, the control cap is fixed to one end of the control screw close to the box door, the control block is threadedly sleeved on the control screw, and the control block is abutted against the bottom of the placement plate, and the end of the transmission plate is hinged to the control block.

[0021] The principle and effect of this technical solution are as follows: the control screw is controlled to rotate by the control cap, so that the control screw can drive the control block to move, and the control block is restricted by the abutment of the placement plate and cannot rotate, so that the control block can drive the transmission plate to move, so that the transmission shaft, transmission plate, control block and transmission groove together form a crank slider structure, that is, the operator can change the position of the connecting plate by controlling the control cap, thereby changing the compression degree of the spring, so that the clamping force of concrete test blocks of different sizes can be reasonably adjusted.

[0022] The utility model is further configured as follows: the control screw is a bidirectional screw, the control blocks are two and symmetrically distributed on the control screw, and two transmission shafts are symmetrically distributed on the bottom of the connecting plate.

[0023] The principle and effect of this technical solution: because the control screw is a bidirectional screw and there are two groups of control blocks, transmission shafts, and transmission plates, when the operator controls the rotation of the control screw through the control cap, the control screw simultaneously controls the two control blocks to indirectly adjust the position of the connecting plate, so that the connecting plate has more force points, so that the force stability of the connecting plate is higher, so that the control component drives the clamping component to move more stably and is not easy to get stuck.

[0024] The utility model is further configured as follows: a plurality of water seepage holes are arranged at intervals on the placement plate.

[0025] The principle and effect of this technical solution: the setting of the water seepage holes facilitates the upper layer of accumulated water to penetrate to the bottom of the moisturizing cavity for recovery. BRIEF DESCRIPTION OF THE DRAWINGS
