Description

Technical Field

[0001] This application relates to the technology of concrete pressure bleeding rate test, and particularly to a concrete pressure bleeding instrument. Background Art

[0002] A concrete pressure bleeding instrument is a test determination device used to test the bleeding volume of pumped concrete under a certain pressure state and calculate the bleeding rate.

[0003] After the existing concrete pressure bleeding instrument is filled with concrete slurry, it is necessary to use a tamping rod to vibrate and discharge the air bubbles in the concrete, and cooperate with a rubber hammer to knock on the outer wall of the cylinder to make the concrete slurry vibrate evenly, so as to avoid the air bubbles and the aggregates in the concrete affecting the accuracy of the bleeding test. The vibration frequency generated by manual vibration and knocking with a tamping rod and a rubber hammer is relatively low, and the vibration effect is poor, which is likely to affect the test results and increase the error. At the same time, the operation is not only time-consuming and laborious, but also the test time is relatively long, delaying the test progress. Utility Model Content

The top of the cylinder body is a pressure component connected detachably, and the bottom is sealed and connected with a base. A vertical rod sealed with the base penetrates and is fixed at the bottom of the base. An elastic telescopic member capable of vertically telescoping up and down is fixed at the upper end of the vertical rod. A vibrator is arranged below the base, and the output port at the upper end of the vibrator is fixed with the lower end of the vertical rod.

[0007] Optionally, the cylinder body is vertically fixed on a tripod, and the legs hinged at the lower end of the tripod can be opened and closed for support.

[0008] Optionally, the vibrator is arranged below the center of the base.

[0011] Compared with the prior art, the beneficial effects of the concrete pressure bleeding instrument provided by this application are:

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following clearly and completely describes the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present application also belong to the scope of protection of the present application.

[0022] As Figures 1-5As shown in the figure, an embodiment of the present application provides a concrete pressure bleeding instrument, which includes a cylinder body 1. The top of the cylinder body 1 is detachably connected with a pressure component 2, and the bottom is hermetically connected with a base 3. A vertical rod 4 sealed with the base 3 penetrates and is fixed at the bottom. An elastic telescopic member 5 capable of vertically telescoping up and down is fixed at the upper end of the vertical rod 4. A vibrator 7 is arranged below the base 3, and an output port 8 at the upper end of the vibrator 7 is fixed to the lower end of the vertical rod 4.

[0023] During use, remove the pressure component 2 and open the upper cover body, load the mixed concrete slurry into the cylinder body 1, and start the vibrator 7. The vibrator 7 conducts vibration from the vertical rod 4 to the elastic telescopic member 5 through the output port 8, so that the elastic telescopic member 5 vibrates in the cylinder body 1 to discharge the air bubbles in the concrete slurry and vibrate the concrete slurry evenly. After vibration compaction, turn off the vibrator 7, cover the pressure component 2 back on the cylinder body 1 and seal and fix it. After pressurizing the concrete slurry in the cylinder body 1 through the pressure component 2, open the drain pipe 14 to take water and measure the bleeding amount. The elastic telescopic member 5 can telescopically move up and down, and can contract downward with the movement when the pressure component 2 presses down, without affecting the pressing action of the pressure component 2. After the measurement is completed, disassemble the cylinder body 1, the pressure component 2 and the base 3 to clean the internal concrete.

[0024] In this embodiment, vibration is generated by the vibrator 7, and the vibration is conducted from the vertical rod 4 to the elastic telescopic member 5, so that the elastic telescopic member 5 vibrates in the cylinder body 1 to discharge the air bubbles in the concrete slurry in the cylinder body 1 and vibrate the concrete slurry in the cylinder body 1 evenly. The vibration frequency generated by the vibrator 7 is higher, and the vibration effect is good, ensuring the accuracy of the test. At the same time, the process of manual vibration and knocking is eliminated, reducing physical consumption and shortening the test time.

[0025] In a possible implementation manner, the elastic telescopic member 5 fixed at the upper end of the vertical rod 4 is a spring 6.

[0026] The spring 6 can generate a greater elastic deformation, and has a greater vibration amplitude and vibration frequency in the range of vibration conduction, and the vibration compaction effect is better. And the spring 6 has a greater telescopic range, can contract in time when the pressure component 2 presses down, and is not easy to fail and damage, and has higher durability.

[0027] In a possible implementation manner, the cylinder body 1 is vertically fixed on a tripod 9, and the legs 10 hinged at the lower end of the tripod 9 can be opened and closed for support.

[0028] The support of the cylinder body 1 by the tripod 9 is convenient for placing and fixing the concrete pressure bleeding instrument during use.

[0029] In a possible implementation, the vibrator 7 is arranged below the center of the base 3. One end of the support leg 10 is hinged to the connecting rod 11, and the other end of the connecting rod 11 extends towards the center and is hinged to the vibrator 7. The output port 8 at the upper end of the vibrator 7 is detachably connected to the lower end of the vertical rod 4.

[0030] When each support leg 10 retracts inwards, the vibrator 7 moves downwards, and the output port 8 is separated from the vertical rod 4, facilitating the removal of the base 3 from the lower end to clean the concrete. During use, open each support leg 10, and each support leg 10 pulls the connecting rod 11 to move the vibrator 7 upwards, so that the output port 8 is plugged and fixed to the bottom of the vertical rod 4. Starting the vibrator 7 can conduct vibration to the vertical rod 4.

[0031] In a possible implementation, a telescopic part 12 for leveling the tripod 9 is provided at the lower end of the support leg 10.

[0032] The telescopic part 12 can extend or retract along the support leg 10 and then be fixed, facilitating leveling the cylinder body 1 to a vertical state through the tripod 9 to ensure the accuracy of the bleeding test.

[0033] In a possible implementation, a rubber ring 13 for shock absorption is fixed between the cylinder body 1 and the tripod 9.

[0034] After the rubber ring 13 is sleeved on the cylinder body 1, it is fixed to the tripod 9. The rubber ring 13 can play a role in shock absorption for the tripod 9. The housing of the vibrator 7 has a shock-absorbing structure and will not conduct vibration to the tripod 9. The rubber ring 13 can prevent the vibration generated at the output port 8 on the vibrator 7 from being conducted to the tripod 9 through the cylinder body 1, enabling the tripod 9 to more stably support the pressure bleeding instrument.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
