Description

Technical Field

[0001] The utility model relates to the technical field of cement compression resistance testing, in particular to a cement compression resistance clamping device. Background Art

[0002] Cement compression test refers to the maximum pressure that cement can withstand when subjected to pressure under specified test conditions. The specific principle of compressive strength test is to use a pressure testing machine to vertically compress the cement test block until the test block is crushed. The maximum load recorded is the compressive strength. During the test using a pressure testing machine, it is usually necessary to use a compression clamp to fix the cement.

[0003] At present, traditional cement compression clamping devices usually use a tension spring to reset the pressure plate after use. When the push rod is subjected to pressure, the spring extends, and when the pressure disappears, the spring resets, thereby driving the pressure plate to reset. After long-term use, the spring may be deformed due to long-term tension, thereby affecting the reset effect of the pressure plate and affecting the normal use of the pressure clamp.

[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following describes the cement compression clamping device according to an embodiment of the present invention with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, the cement compression-resistant clamping device of the embodiment of the present invention includes: a clamping member 1 and a plurality of return springs 2.

[0023] The clamping member 1 includes a housing 11 , a connecting column 12 , a push plate 13 and a pressing plate 14 .

[0024] Among them, the pressure plate 14 is installed inside the shell 11, the connecting column 12 passes through the shell 11 and is connected to one end of the connecting column 12, the push plate 13 is connected to the other end of the connecting column 12, and multiple return springs 2 are equidistantly arranged under the push plate 13.

[0025] A receiving groove 31 is provided on the shell 11, and the other end of the return spring 2 is connected to the bottom wall of the receiving groove 31. A telescopic column 32 is provided inside the return spring 2, and one end of the telescopic column 32 is connected to the bottom wall of the receiving groove 31, and the other end of the telescopic column 32 is connected to the push plate 13.

[0026] It should be noted that the depth of the receiving groove 31 described in this embodiment should be greater than the height of the return spring 2 after it is fully compressed, and the height of the telescopic column 32 after it is fully retracted should be less than the depth of the receiving groove 31. For example, if the depth of the receiving groove 31 is 10CM, then the height of the return spring 2 after it is fully compressed should be less than or equal to 10CM and the height of the telescopic column 32 after it is fully retracted should also be less than or equal to 10CM. This ensures that the receiving groove 31 will not affect the normal reciprocating motion of the connecting column 12 while normally accommodating the return spring 2.

[0027] Specifically, cement is placed inside the shell 11, and then relevant staff applies pressure to the push plate 13 through the pressure testing machine, and then transmits the force to the pressure plate 14 through the connecting column 12. At this time, the pressure plate 14 moves downward to apply pressure to the cement to be tested, completing the pressure test of the cement.

[0028] When the push plate 13 moves downward, the return spring 2 is compressed and stored in the storage groove 31. The telescopic column 32 can limit the movement trajectory of the return spring 2. The pressure applied by the contact pressure testing machine drives the push plate 13 to move upward through the return spring 2. The push plate 13 drives the pressure plate 14 to reset through the connecting column 12. Long-term squeezing of the return spring 2 will not affect the force storage effect of the return spring 2, thereby ensuring the normal reset of the pressure plate 14.

[0029] In one embodiment of the present invention, Figures 1-4 As shown, the outer wall of the housing 11 is symmetrically provided with a sliding groove 41 , the inner wall of the sliding groove 41 is slidably connected with a slider 42 , and one side of the slider 42 is connected to the pressure plate 14 .

[0030] It is understandable that, when the pressing plate 14 moves downward, the slider 42 will slide up and down inside the sliding groove 41 , thereby limiting the pressing plate 14 .

[0031] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, balls 43 are symmetrically arranged inside the slider 42.

[0032] It is understandable that providing the ball bearings 43 can reduce the friction between the slider 42 and the slide groove 41 .

[0033] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the lower wall of the pressing plate 14 and the inner wall of the shell 11 are both provided with anti-skid pads 51 , and the surface of the anti-skid pads 51 is provided with anti-skid grooves 52 .

[0034] It is understandable that the provision of the anti-slip pad 51 and the anti-slip groove 52 can increase the friction between the cement and the clamping member 1, thereby preventing the cement from falling off the clamping member 1 when pressure is applied to the cement.

[0035] In summary, the cement compression-resistant clamping device of the present invention can increase the service life of the spring and improve the resetting effect of the pressure plate in the clamping part by changing the deformation mode of the spring after being subjected to force.
