DETAILED DESCRIPTION

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Embodiment 1

[0033] Reference Figures 1 to 4The utility model provides a grouting slurry fluidity test device, including a base 1, a test frame 2 is arranged on the base 1, a fluidity cone 3 is arranged on the top of the test frame 2, and the fluidity cone 3 is located just above the center of the base 1. The base 1 includes a leveling assembly, which includes a bottom plate 4 and a support plate 5 arranged above the bottom plate 4, and a plurality of rotating sleeves 6 are arranged on the upper surface of the bottom plate 4. The lower end of the rotating sleeve 6 is connected to the bottom plate 4 through a universal joint, and a rotating screw 7 is arranged in the rotating sleeve 6 through a bearing. A rotating sleeve 8 is threadedly sleeved on the outside of the rotating screw 7, and the top end of the rotating sleeve 8 is connected to the support plate 5 through a universal joint.

[0034] In the leveling assembly, the rotating sleeve 8 can be driven to move along the axial direction of the rotating screw 7 by rotating the rotating screw 7, so as to adjust the distance between the support plate 5 and the base plate 4. The number of rotations of each rotating screw 7 is different, so that the distance between the support plate 5 and the base plate 4 is different at different locations, so that the support plate 5 can be adjusted to different planes.

[0035] Further, a loading groove 25 is provided on the support plate 5, a drain port 26 is provided at the edge of the loading groove 25, a leveling groove 27 is provided at the edge of the support plate 5, a transparent sealing cover 28 is provided at the top of the leveling groove 27, the lower surface of the transparent sealing cover 28 is concave to form a spherical surface, a leveling chamber 30 is formed between the transparent sealing cover 28 and the leveling groove 27, the leveling chamber 30 is filled with water and air, the air gathers at the top of the leveling chamber 30 to form a leveling bubble 31, and a screw knob 29 is fixedly sleeved on the rod body of the rotating screw 7. By observing the leveling bubble 31, it can be judged whether the support plate 5 is level, thereby providing guidance for subsequent leveling.

[0036] Since the center of gravity of the test device remains unchanged, no matter it is in an inclined state or a horizontal state, the distance between the hinge point of the rotating sleeve 8 and the support plate 5 and the center of gravity does not change, so the pressure on each rotating sleeve 8 is consistent.

[0037] This embodiment can change the center of gravity position of the test device by setting a center of gravity adjustment component, so that when the test device is in different tilt states, its center of gravity position changes, causing the distance between the hinge point of each rotating sleeve 8 and the support plate 5 and the center of gravity to change, thereby different pressures are applied to each rotating sleeve 8.

[0038] In this way, whether the test device is leveled can be judged by whether the pressure exerted on each rotating sleeve 8 is consistent. At the same time, the pressure exerted on each rotating sleeve 8 can be used as a guide to guide the leveling component to move and quickly level the device.

[0039] Specifically, refer to Figure 4The center of gravity adjustment assembly in this embodiment includes a counterweight adjustment seat 9 arranged on the lower surface of the support plate 5. The interior of the counterweight adjustment seat 9 is hollow to form a counterweight adjustment cavity 10. The bottom surface of the counterweight adjustment cavity 10 is concave to form a spherical groove 11. A counterweight ball 12 is movably arranged in the spherical groove 11. When the support plate 5 is in a horizontal state, the counterweight ball 12 is located at the center position of the spherical groove 11, resulting in the same distance between the hinge point of each rotating sleeve 8 and the support plate 5 and the center of gravity, and the same pressure on each rotating sleeve 8. When the support plate 5 is tilted, the counterweight ball 12 moves away from the center position of the spherical groove 11, changing the center of gravity position of the test device, resulting in different distances between the hinge point of each rotating sleeve 8 and the support plate 5 and the center of gravity, and different pressure on each rotating sleeve 8.

[0040] During the leveling operation, the force on each rotating sleeve 8 is related to its distance from the center of gravity. The farther away from the center of gravity, the smaller the force, and vice versa. Therefore, when the support plate 5 is tilted, the rotating sleeve 8 subjected to increased pressure is at the bottom, so the rotating screw 7 in the rotating sleeve 8 needs to be extended.

[0041] It should be noted that in this embodiment, the counterweight adjustment seat 9 is supported by a transparent material, so the position of the counterweight ball 12 can be observed intuitively from the outside, and at the same time, it can be judged whether the support plate 5 is in a horizontal state according to the position of the counterweight ball 12. When the counterweight ball 12 is at the center of the spherical groove 11, the support plate 5 is in a horizontal state, otherwise it is in an inclined state, and the support plate 5 is inclined to the side of the center position where the counterweight ball 12 is located.

[0042] In this way, in the present embodiment, when performing the leveling operation, the position of the weighted ball 12 can be used as a guide, thereby achieving rapid leveling.

The adjustment bevel gear 17 is meshed with the screw bevel gear 13. By twisting the adjustment knob 16, the adjustment shaft 15 can be driven to rotate, and then the adjustment bevel gear 17 can be rotated, so that the screw bevel gear 13 and the rotating screw 7 are rotated to achieve leveling drive.

[0045] To further facilitate the leveling operation, refer to Fig. 9A pressure sensor 18 is arranged between the rotating sleeve 8 and the supporting plate 5. A pressure display 19 is arranged on the outer surface of the rotating sleeve 8. The pressure display 19 is electrically connected to the pressure sensor 18. The pressure between the rotating sleeve 8 and the supporting plate 5 can be visually observed through the pressure display 19, thereby providing guidance for the leveling operation.

[0046] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0047] This embodiment can change the center of gravity position of the test device by setting a center of gravity adjustment component, so that when the test device is in different tilt states, the center of gravity position changes, causing the distance between the hinge point of each rotating sleeve 8 and the support plate 5 and the center of gravity to change. As a result, the pressure exerted on each rotating sleeve 8 is different, providing guidance for subsequent leveling operations and achieving rapid leveling.
