Description

Technical Field

[0001] The utility model relates to a test block curing box, in particular to a test block constant temperature and humidity curing box. Background Art

[0002] According to the "Concrete Structure Engineering Construction Quality Acceptance Code", after demoulding, the test blocks need to be cured in a standard curing box for 28 days, and then subjected to compressive testing to determine whether their compressive strength meets the requirements. For small mortar test blocks, the existing curing box is usually equipped with multi-layer test block placement racks. Usually, several rows of test blocks can be placed in one rack. Because the test blocks in the outer row will block the test blocks in the inner row, the test blocks in the inner row are not easy to take out when taking them out, which affects the removal of the test blocks.

[0003] Patent document CN220428760U discloses a test block picking and placing device for a concrete curing workshop, which stores the test blocks by arranging multiple layers of coaxial rotating trays, and rotates the inner side to the outer side by rotating the trays, so as to facilitate loading and unloading.

[0004] When the curing amount of test blocks is large, in order to ensure that the test blocks can fully reach the 28-day curing, each batch of test blocks on the shelves needs to be date-marked. Therefore, in the daily use of the curing box, the test blocks may be put on and taken off the shelves at the same time. When the staff who put the test blocks on the shelves store the test blocks on the rotating tray, it may affect the staff who take the test blocks off the shelves from viewing the date marks. Therefore, a test block curing box is needed that can facilitate the putting on and taking off of the test blocks without affecting the simultaneous work of both. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0023] See also Figures 1 to 6 The utility model provides a constant temperature and humidity curing box for test blocks, comprising a box body 1 and a constant temperature and humidity module, the constant temperature and humidity module is connected to the inside of the box body 1, a main rotating shaft 2 is arranged in the box body 1, the upper and lower ends of the main rotating shaft 2 are rotatably connected to the inner wall of the box body 1, a plurality of load-bearing platforms 3 are equidistantly arranged on the main rotating shaft 2, the load-bearing platform 3 is coaxially and fixedly connected to the main rotating shaft 2, a placement plate 4 is arranged on the top of the load-bearing platform 3, the placement plate 4 is movably connected to the main rotating shaft 2, a two-way rotation mechanism is also arranged between the placement plate 4 and the load-bearing platform 3, the load-bearing platform 3 can drive the placement plate to rotate in the same direction through the two-way rotation mechanism, and the placement plate can rotate on its own while the load-bearing platform 3 remains stationary through the two-way rotation mechanism.

[0024] The constant temperature and humidity module of the curing box can be purchased online or in physical stores, such as SHIKE-ZByinan's intelligent temperature and humidity control box, which can provide a constant temperature and humidity curing environment for the inside of the box 1. This device is divided into two practical scene modes:

[0025] Scenario 1 is that only one staff member operates. When putting the test blocks 12 on the shelves, the test blocks 12 can be first stacked in the area on the outward side of the placement tray 4, and then the load-bearing platform 3 is rotated to drive the placement tray 4 to rotate synchronously in the same direction through the two-way rotation mechanism, and the test blocks 12 are rotated from the outside to the inside, and the original vacant area on the inside is rotated to the outward side, which is convenient for the staff to continue to put on the shelves, and the same is true for the operation of taking off the shelves;

[0026] Scenario 2 is, when there are two staff members operating, one responsible for putting on the shelves and the other responsible for taking off the shelves, they only need to rotate the placement tray 4 that they are responsible for. Under the action of the two-way rotation mechanism, the load-bearing platform 3 remains stationary, and the other placement trays 4 also remain stationary when not affected by external force. Only the two placement trays 4 on the upper and lower shelves rotate independently with the rotation of the staff members. Therefore, during the simultaneous operations of putting on and taking off the shelves, the two do not affect each other, thereby improving the work efficiency of putting on and taking off the shelves.

[0027] The bidirectional rotating mechanism includes a rotating ring 5, a clamping strip 6 and a clamping slot 7. The bottom of the placement plate 4 is rotatably connected to the top of the load-bearing platform 3 through the rotating ring 5. The top of the load-bearing platform 3 is provided with a plurality of clamping slots 7 along the circumferential direction. The bottom of the placement plate 4 is provided with a plurality of slide grooves 8 corresponding to the slide grooves 7 along the circumferential direction. The clamping strip 6 is slidably installed in the slide groove 8. When the slide groove 8 and the clamping slot 7 are located on the same vertical line, the bottom end of the clamping strip 6 slides freely into the clamping slot 7. The bottom of the clamping strip 6 is provided with arc-shaped force-bearing teeth 9.

[0028] A limiting block 10 is provided on the top of the clamping strip 6 .

[0029] A circular hole 11 is opened at the center of the placement plate 4 , and the placement plate 4 is sleeved on the outer side of the main shaft 2 through the circular hole 11 . The inner diameter of the circular hole 11 is greater than the outer diameter of the main shaft 2 .

[0030] The front end of the force-bearing tooth 9 is an arc surface, and the rear end of the force-bearing tooth 9 is a vertical plane. The direction of the arc surface is along the direction of clockwise rotation. When the clamping strip 6 is at the lowest point, the top of the arc surface of the force-bearing tooth 9 is located above the clamping slot 7.

[0031] Rotate the load-bearing platform 3 clockwise, and under the synchronous action of the main shaft 2, drive all the load-bearing platforms 3 to rotate synchronously. During the rotation of the load-bearing platform 3, the inner wall of the slot 7 abuts against the rear end of the force-bearing tooth 9, pushing the force-bearing tooth 9 to move. Under the action of the force-bearing tooth 9, drive the placement plates 4 of each layer to rotate synchronously in the clockwise direction, which is convenient for a single staff member to operate, and is suitable for the above-mentioned scenario 1;

[0032] Taking into account the effect of friction, the staff can support the bottom of the load-bearing platform 3 with one hand and push the placement plate 4 to rotate clockwise with the other hand. During the rotation of the placement plate 4, the front end of the force-bearing tooth 9 abuts against the inner wall of the slot 7. Under the action of force, the arc surface can drive the force-bearing tooth 9 and the card strip 6 to move upward, and the card strip 6 retracts into the slide groove 8, and the force-bearing tooth 9 is separated from the inside of the slot 7. Therefore, the placement plate 4 can rotate clockwise alone when the load-bearing platform 3 is stationary, without affecting the placement plates 4 on other layers. Therefore, during the simultaneous operation of putting on and taking off the shelves, the two do not affect each other, thereby improving the work efficiency of putting on and taking off the shelves.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
