Description

Technical Field

[0001] The present invention relates to the technical field of mold cleaning and spraying, and more particularly to a mold cleaning and spraying device for a concrete test piece. Background Art

[0002] Concrete specimens are samples used to test concrete material properties, including but not limited to compressive strength, tensile strength, and elastic modulus. Concrete specimens are produced and tested to ensure that the concrete used in construction meets design requirements and guarantees the safety and durability of the structure. Energy-saving concrete, a concrete material designed to improve the energy efficiency of buildings, is increasingly being used due to its low thermal conductivity, lightweight, and high durability.

[0003] Concrete specimen molds are used to form concrete test blocks, ensuring they have a uniform, standard size and shape for accurate mechanical property testing. Concrete specimen molds should be cleaned immediately after each use to prevent concrete from hardening on the mold surface. Applying a release agent to the mold's inner surface after cleaning effectively reduces adhesion between the concrete and the mold, facilitating demolding, reducing the amount of concrete residue adhering to the mold, and improving the surface finish of the specimen.

[0004] Currently, the cleaning of specimen molds and the application of release agents are mainly done manually. Operators use handheld flushing equipment to flush and clean the inside and outside of the mold, and manually apply or spray the inner wall of the mold after cleaning. However, this method requires a lot of labor and time. Especially in the case of large-scale projects, the cleaning efficiency of concrete specimen molds is low, which greatly slows down the production process of the specimens. It is also easy to fail to clean them properly, affecting the production quality of subsequent specimens.

[0058] In use, before the test piece mold 1 is placed on the device, the distance between the adjacent four clamping pieces 5 on the receiving plate 4 is slightly greater than the length of each side of the test piece mold 1. Then the test piece mold 1 after demolding is placed on each clamping piece 5, and at this time the test piece mold 1 can be supported by the clamping piece 5. Then the transmission mechanism 6 drives the four clamping pieces 5 to move synchronously, that is, the opposite clamping pieces 5 move towards each other, so that the four clamping pieces 5 can clamp and fix the four sides of the test piece mold 1, thereby ensuring the stability of the test piece mold 1 and preventing the test piece mold 1 from shifting and shaking during subsequent cleaning and spraying, greatly improving the quality and effect of cleaning and spraying, and having high practicability.

[0059] After the test piece mold 1 is fixed, the inner wall of the test piece mold 1 is washed by the inner spraying mechanism 7, and the outer wall of the test piece mold 1 is washed by the outer spraying mechanism 9 at the same time. The lifting mechanism 10 drives the lifting plate 8 and the outer spraying mechanism 9 to move up and down, so that the outer spraying mechanism 9 can thoroughly wash the outer wall of the test piece mold 1, thereby improving the cleaning effect of the test piece mold 1.

[0063] The driving component 65 is used to drive the rotating disc 61 to rotate.

[0064] In this way, the rotating disc 61 can be driven to rotate by the driving component 65, the rotating disc 61 drives the arc-shaped groove 62 to rotate, so that the shaft column 64 moves along the arc-shaped groove 62, the shaft column 64 drives the sliding plate 63 to slide along the sliding groove 11, and the clamping piece 5 moves horizontally. Figure 5-6 For example, when the driving component 65 drives the rotating disc 61 to rotate clockwise, the rotating disc 61 drives the sliding plate 63 and the clamping piece 5 to move towards the rotating disc 61 through the cooperation of the arc-shaped groove 62 and the shaft column 64, that is, the area surrounded by the clamping pieces 5 is reduced at this time, and the test piece mold 1 is clamped; on the contrary, when the driving component 65 drives the rotating disc 61 to rotate counterclockwise, the sliding plate 63 and the clamping piece 5 move away from the rotating disc 61, the area surrounded by the clamping pieces 5 is increased, and the test piece mold 1 is conveniently taken and placed, and the operation is simple and convenient.

Specifically, the first driving piece 651 in the application can adopt a servo motor, and the first driving piece 651 drives the driving gear 652 to rotate, and the driving gear 652 drives the rotating disc 61 to rotate through the gear ring 653, so that the rotating disc 61 is driven to rotate forward or reverse through the forward and reverse rotation of the first driving piece 651.

[0067] Through the driving of the first driving piece 651 in the driving component 65, the rotating disc 61 drives the plurality of clamping pieces 5 to move synchronously, without the need to set driving pieces at each clamping piece 5, so that the synchronization effect of the clamping pieces 5 is better, the driving piece error is reduced, and the clamping effect of the clamping pieces 5 is affected; and through the driving of the single first driving piece 651, a large amount of electric energy and driving piece waste is saved, the procurement cost is reduced, and the energy saving is good.

[0068] The receiving plate 4 is provided with a support 23 which is connected with the rotating disc 61 to slide, and the rotating disc 61 is provided with a ring plate 24, and the support 23 is provided with an arc-shaped sliding groove which is adapted to slide with the ring plate 24. When the driving component 65 drives the rotating disc 61 to rotate, the rotating disc 61 rotates along the support 23, the support 23 supports the rotating disc 61, and the ring plate 24 on the rotating disc 61 slides along the arc-shaped sliding groove on the support 23, so that the rotating smoothness and stability of the rotating disc 61 are improved.

Before the test piece mold 1 is placed, the distance between the adjacent clamping pieces 5 is slightly larger than the length of each side of the test piece mold 1. When the test piece mold 1 is placed on the bottom support block 52, the four sides of the test piece mold 1 fall on the four bottom support blocks 52 of the clamping pieces 5 respectively. Then, when the clamping piece 5 moves, the side baffle 53 limits and clamps the side of the test piece mold 1, and the upper limiting plate 54 limits and clamps the vertical direction of the test piece mold 1. That is, the horizontal and vertical directions of the test piece mold 1 can be limited by the clamping piece 5, so as to achieve the clamping and fixing effect of the test piece mold 1.

When different sizes of test piece molds 1 are needed later, the position of the clamping piece 5 can be adjusted, so that different test piece molds 1 can be conveniently clamped and used. Only the position of the vertical rod 51 on the sliding plate 63 needs to be manually adjusted, without the need to change the parameters of the first driving piece 651 to change the rotation degree of the rotating disc 61. The parameters of the first driving piece 651 are not easy to control and adjust, and the staff cannot adjust them well. At this time, only the position of the vertical rod 51 needs to be manually adjusted. After the adjustment is completed, the adjusting bolts 14 are screwed into the corresponding adjusting holes 13 to fix the sliding seat 12. The number of rotations of the rotating disc 61 driven by the driving part 65 is the same, but the position of the vertical rod 51 on the sliding plate 63 is adjusted, that is, the positions of the clamping pieces 5 are changed to adapt to different situations.
