Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a concrete permeameter for concrete detection. Background Art

[0002] Nowadays, concrete is widely used in the construction field. Concrete is an artificial stone widely used in construction. For some buildings, such as tunnels, hydraulic structures and other construction projects, the concrete used in the building is required to have specific anti-seepage properties. When using concrete, it is often necessary to test its permeability, which is called concrete anti-seepage. Concrete anti-seepage meter is mainly used for testing the anti-seepage performance of concrete and determining the anti-seepage grade. Concrete anti-seepage refers to the ability of concrete to resist the penetration of pressurized water. The destruction process of concrete durability is almost closely related to water. Therefore, anti-seepage has become an important indicator for evaluating the durability of concrete.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 、 Figure 2 As shown, a concrete permeameter for concrete testing includes a base 1, a plurality of laterally distributed control valves 2 are movably installed on the front side of the base 1 near the upper side, four rectangularly distributed universal wheels 3 are rotatably connected to the lower side of the base 1 near the four corners, a water injection pipe 4 is fixedly connected to the left side of the base 1 near the lower side, a plurality of evenly distributed placement platforms 5 are fixedly connected to the upper surface of the base 1, a plurality of rectangularly distributed fixing mechanisms 6 are fixedly connected to the upper surface of the base 1, and the placement platforms 5 are located on the inner side of the fixing mechanisms 6, and molds 7 are movably sleeved on the inner sides of the plurality of fixing mechanisms 6.

[0025] It should be noted that a rubber ring is embedded in the upper side of the placement table 5 near the edge to prevent water from overflowing from the gap between the placement table 5 and the mold 7.

[0026] like Figure 2-Figure 5 As shown, the fixing mechanism 6 includes a mechanism sleeve 61, the lower side of the mechanism sleeve 61 is fixedly connected to the upper side of the base 1, and the placement table 5 is located on the inner side of the mechanism sleeve 61, and the outer side of the mechanism sleeve 61 is rotatably connected to a gear ring 62 near the upper side, and the middle part of the outer side of the mechanism sleeve 61 is rotatably connected to four annularly distributed threaded sleeves 63, and the outer sides of the four threaded sleeves 63 are fixedly connected to gears 64, and the upper side of the gear 64 is meshed and connected with the lower side of the gear ring 62, and the inner sides of the four threaded sleeves 63 are threadedly connected to screws 65.

[0027] It should be noted that, when the ring gear 62 is rotated, the ring gear 62 drives the gear 64 to rotate, and when the gear 64 rotates, the threaded sleeve 63 is driven to rotate, and when the threaded sleeve 63 rotates, the screw 65 moves axially along the inner side of the mechanism sleeve 61.

[0028] like Figure 3-Figure 5 As shown, the four screws 65 are fixedly connected to two horizontally distributed first springs 66 on the side close to the mold 7 through a vertical plate, and the first spring 66 is fixedly connected to a push plate 67 on the side away from the threaded sleeve 63, and four push plates 67 are distributed in a ring, and the inner side of the push plate 67 is movably sleeved with a number of ring-distributed blocks 68, and the lower side of the block 68 is slidably connected to the slide groove opened on the upper side of the base 1, the lower side of the mold 7 is overlapped on the upper side of the placement table 5, and the lower side of the upper wall of the block 68 is overlapped on the upper surface of the flange on the lower side of the mold 7.

[0029] It should be noted that when the screw 65 moves, it pushes the block 68 to move, causing the block 68 to push the push plate 67 together, so that the upper wall of the block 68 is pressed tightly against the flange on the lower side of the mold 7, so that the mold 7 is fixed. The setting of the first spring 66 allows the screw 65 to continue to move, so as to further increase the pressure of the block 68 on the flange on the lower side of the mold 7, and avoid the problem of directly pushing the push plate 67 and causing the push plate 67 to move too much and cause damage to the components. The first spring 66 is used to stabilize the push plate 67 and the vertical plate, so that the screw 65 and the push plate 67 are in the same state.

[0030] like Figure 4 As shown, the four push plates 67 are rotatably connected to two symmetrically distributed telescopic rods 610 at the positions near the two ends of the horizontal side away from the mold 7, and the end of the telescopic rod 610 away from the mold 7 is rotatably connected to the inner middle part of the mechanism sleeve 61.

[0031] It should be noted that the telescopic rod 610 is used to stabilize the push plate 67 so that the push plate 67 does not deflect when it is displaced, and at the same time ensures that the threaded sleeve 63 does not drive the screw rod 65 to rotate when it rotates.

[0032] like Figure 5 As shown, the upper wall of the block 68 is in the shape of an isosceles trapezoid.

[0033] It should be noted that the shape of the block 68 is such that when the mold 7 is installed, the flange on the lower side thereof will push the inclined surface on the upper side of the upper wall of the block 68, causing the block 68 to move away from each other. When the mold 7 is being removed, the flange on the lower side of the mold 7 will push the inclined surface on the lower side of the upper wall of the block 68, causing the block 68 to move away from each other.

[0034] like Figure 4 、 Figure 5 As shown, four rectangularly distributed second springs 69 are fixedly connected between the positions of the four corners of the side of the plurality of clamping blocks 68 close to the threaded sleeve 63 and the inner side of the mechanism sleeve 61 .

[0035] It should be noted that the second spring 69 is a tension spring, so when the push plate 67 does not push the block 68, the second spring 69 will pull the block 68, so that the blocks 68 are in the same state, preventing the blocks 68 from moving at will and affecting the installation and disassembly of the mold 7.

[0036] The working principle of the present invention is as follows: first, the gear ring 62 is rotated, causing the gear ring 62 to drive the gear 64 to rotate. When the gear 64 rotates, it drives the threaded sleeve 63 to rotate. When the threaded sleeve 63 rotates, the screw 65 moves axially along the inner side of the mechanism sleeve 61. When the screw 65 moves, it pushes the block 68 to move, causing the block 68 to push the push plate 67 closer, so that the upper wall of the block 68 is pressed against the flange on the lower side of the mold 7, so that the mold 7 is fixed. The setting of the first spring 66 allows the screw 65 to continue to move, so as to further increase the pressure of the block 68 on the flange on the lower side of the mold 7, so as to avoid the problem of excessive movement of the push plate 67 caused by directly pushing the push plate 67 and causing damage to the components. The first spring 66 is used to stabilize the push plate 67 and the vertical plate, so that the screw 65 and the push plate 67 are in the same state. By rotating the mechanism sleeve 61, the push plate 67 is moved, so that the push plate 67 pushes the block 68 to quickly fix the mold 7. Only one rotation is required to drive all The rotation of gear 64 greatly shortens the time of fixing the mold 7 and improves the installation efficiency of the mold 7. Finally, the shape of the block 68 is such that when the mold 7 is installed, the flange on the lower side thereof pushes the inclined surface on the upper side of the upper wall of the block 68, causing the block 68 to move to the side away from each other. When the mold 7 is being removed, the flange on the lower side of the mold 7 pushes the inclined surface on the lower side of the upper wall of the block 68, causing the block 68 to move to the side away from each other. The second spring 69 is a tension spring, so that when the push plate 67 does not push the block 68, the second spring 69 will pull the block 68, so that the blocks 68 are in the same state, avoiding that each block 68 moves at will and affects the installation and removal of the mold 7. The block 68 is stabilized by the second spring 69, and relying on the shape of the upper wall of the block 68, the mold 7 can be quickly inserted and removed, avoiding that the block 68 obstructs the outer bottom flange of the mold 7, which is convenient for quickly placing the mold 7 when fixing the mold 7.
