Description

Technical Field

[0001] This utility model relates to the field of cement testing technology, and in particular to a cement mortar vibration table. Background Technology

[0002] The cement mortar vibration table is a special equipment used to prepare cement strength test samples. The equipment consists of a vibration component, a frame component and a proximity switch programmable control system. It uses a synchronous motor to drive a cam to achieve periodic vibration.

[0003] In actual testing work, due to differences in cement type, testing purpose, and industry standards, different sizes of test molds (such as prism or cube test molds of different sizes) are often required. However, the existing cement mortar vibration table uses welding or bolt fastening to directly fix the test mold limiting clamps to the test mold bearing platform. The distance between the clamps on both sides is fixed to a specific size. This fixed structure means that the equipment can only be adapted to one or a few sizes of test molds. When it is necessary to change to a different size test mold, the limiting clamps cannot be adjusted according to the size of the test mold, thus reducing applicability. Therefore, a cement mortar vibration table is proposed to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a cement mortar vibration table. By setting a movable frame, sliding components, and threaded openings in multiple positions, the position of the mold limiting fixture can be adjusted, thus broadening the scope of application and improving the utilization rate of the equipment.

[0005] (II) Technical Solution This utility model provides a cement mortar vibration table, including a cement mortar vibration table body, a cement mortar vibration table cover, a vibration table surface, and a test mold support platform. The cement mortar vibration table cover is hinged to the edge of the mounting opening of the cement mortar vibration table body. The vibration table surface is horizontally installed at the vibration output end at the top of the cement mortar vibration table body. The test mold support platform is coaxially fixed to the upper middle part of the vibration table surface. It also includes symmetrically distributed test mold limiting clamps and moving frames. Two sets of moving frames are symmetrically arranged on both sides of the upper surface of the test mold support platform along the length direction. Both sides of the moving frames are connected to the sliding components through vertically fixed side plates. The sliding components are arranged on the side of the test mold support platform along the width direction. The trial mold limiting fixture is installed on the upper surface of the movable frame. Multiple sets of threaded openings are provided on both sides of the upper surface of the trial mold support platform, which are equidistant along the length direction. The threaded openings are located in the area directly below the movable frame. The outer wall of the movable frame is also equipped with a limiting component that can cooperate with the threaded openings for locking.

[0006] Furthermore, the sliding assembly includes a slide rod frame, a slide rod, and a slide sleeve. The slide rod frame has a U-shaped structure with its opening facing upwards, and its bottom is fixed to the upper end face of the vibration table. The slide rod is horizontally fixed between the inner walls of both sides of the slide rod frame. The slide sleeve is gapped on the outer wall of the slide rod and can slide along the slide rod. The upper end face of the slide sleeve is welded and fixed to the lower end face of the side plate.

[0007] Furthermore, the upper surface of the test mold support platform is polished to form a smooth plane, and the lower surface of the movable frame is fitted to the upper surface of the test mold support platform, and the lower surface of the movable frame is also polished.

[0008] Furthermore, the limiting component includes a mounting plate and a butterfly bolt. The mounting plate is vertically welded to the outer wall of the movable frame, and the mounting plate has a through hole that matches the diameter of the threaded opening. The butterfly bolt passes through the through hole of the mounting plate and is threadedly connected to any one of the threaded openings to lock the position of the movable frame.

[0009] Furthermore, a handle is welded to the middle of the outer wall of the cement mortar compaction table cover.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-4As shown, the present invention proposes a cement mortar vibration table, comprising a cement mortar vibration table body 4, a cement mortar vibration table cover 1, a vibration table surface 5, and a mold support platform 6. The cement mortar vibration table cover 1 is hinged to the edge of the mounting opening of the cement mortar vibration table body 4, facilitating the opening and closing of the cement mortar vibration table cover 1. When the table is in operation, the cement mortar vibration table cover 1 can be closed to provide protection and sound insulation. The vibration table surface 5 is horizontally installed at the vibration output end at the top of the cement mortar vibration table body 4. The vibration table surface 5 receives the vibration energy transmitted by the vibration table body and transmits it to the mold support platform 6. The mold support platform 6 is coaxially fixed to the upper middle part of the vibration table surface 5. The mold support platform 6 is used to place the mold and provide a stable support platform for the mold. The cement mortar vibration table also includes symmetrically distributed mold limiting clamps 8 and moving frames 9. The two sets of moving frames 9 are symmetrically arranged on both sides of the upper end face of the mold support table 6 along the length direction. The moving frames 9 can move along the width direction of the mold support table 6, thereby driving the mold limiting clamps 8 to adjust their positions. Both ends of the moving frames 9 are connected to the sliding components through vertically fixed side plates 13. The sliding components are arranged on the side of the mold support table 6 along the width direction. The sliding components provide guidance and support for the movement of the moving frames, ensuring that the moving frames move smoothly.

[0022] The mold limiting clamp 8 is installed on the upper surface of the movable frame 9. The mold limiting clamp 8 is used to limit and fix the mold placed on the mold support platform 6 to prevent the mold from shifting during vibration. Multiple sets of threaded holes 14 are provided on both sides of the upper surface of the mold support platform 6, which are equidistant along the length direction. The threaded holes 14 are located in the area directly below the movable frame 9. The threaded holes 14 provide multiple fixing positions for the limiting components, which are convenient to fix the movable frame 9 after adjusting its position according to the size of the mold. The outer wall of the movable frame 9 is also equipped with a limiting component that can be locked in conjunction with the threaded holes 14. When the movable frame is adjusted to a suitable position, the position of the movable frame 9 is locked by the limiting component engaging with the corresponding threaded holes 14, ensuring the fixing effect of the mold limiting clamp 8 on the mold.

[0023] In this embodiment, the sliding assembly includes a slide bar frame 15, a slide bar 16, and a slide sleeve 17. The slide bar frame 15 has a U-shaped structure with its opening facing upwards. Its bottom is fixed to the upper end face of the vibration table 5. The slide bar frame 15 provides stable mounting support for the slide bar 16. The slide bar 16 is horizontally fixed between the inner walls on both sides of the slide bar frame 15. The slide bar 16 provides guidance for the sliding of the slide sleeve 17. The slide sleeve 17 is fitted with a gap on the outer wall of the slide bar 16 and can slide along the slide bar 16. The upper end face of the slide sleeve 17 is welded and fixed to the lower end face of the side plate 13.

[0024] It should be noted that when the movable frame 9 needs to be moved, the sliding sleeve 17 slides along the sliding rod 16, causing the side plate 13 and the movable frame 9 to move synchronously, ensuring the straightness and stability of the movement of the movable frame 9.

[0025] In this embodiment, the upper surface of the test mold support platform 6 is polished to form a smooth plane, and the lower surface of the movable frame 9 is fitted to the upper surface of the test mold support platform 6, and the lower surface of the movable frame 9 is also polished.

[0026] In this embodiment, the limiting component includes a mounting plate 10 and a butterfly bolt 11. The mounting plate 10 is vertically welded to the outer side wall of the movable frame 9. The mounting plate 10 provides a mounting carrier for the butterfly bolt 11. The mounting plate 10 has a through hole that matches the diameter of the threaded opening 14. After the butterfly bolt 11 passes through the through hole of the mounting plate 10, it is threadedly connected to any one of the threaded openings 14 to lock the position of the movable frame 9.

[0027] It should be noted that the butterfly bolt 11 can be tightened or loosened manually without the aid of tools, making it easy to operate.

[0028] In this embodiment, a handle 7 is welded to the middle of the outer wall of the cement mortar compaction table cover 1.

[0029] It should be noted that the handle 7 allows operators to easily open and close the cover 1 of the cement mortar compaction table.

[0030] In this embodiment, the inner wall of the cement mortar vibrating table cover 1 is fixed with a first sound insulation board 2 by an adhesive, and the inner wall of the cement mortar vibrating table body 4 is fixed with a second sound insulation board 3 by bolts. Both the first sound insulation board 2 and the second sound insulation board 3 are made of porous sound-absorbing material.

[0031] It should be noted that both the first sound insulation panel 2 and the second sound insulation panel 3 are made of porous sound-absorbing material. When noise is generated, some of the noise is transmitted through the air to the surfaces of the first sound insulation panel 2 and the second sound insulation panel 3. The sound waves enter the pores inside the porous sound-absorbing material, where they are continuously reflected, refracted, and rubbed. The sound energy is gradually converted into heat energy and consumed, thereby reducing the propagation of the noise. At the same time, the tight fit between the cement mortar vibrating table cover 1 and the main body 4 of the cement mortar vibrating table can also block the outward diffusion of noise to a certain extent, further improving the noise level of the equipment's working environment.

[0032] In this embodiment, the movable frame 9 is connected to one side of the corresponding side plate 13 by a second reinforcing plate 18, and the movable frame 9 is connected to the other side of the corresponding side plate 13 by a first reinforcing plate 12.

[0033] It should be noted that the first reinforcing plate 12 and the second reinforcing plate 18 enhance the stability and firmness of the connection between the movable frame 9 and the side plate 13, effectively improving the structural strength of the connection between the movable frame 9 and the side plate 13.

[0034] Working principle: First, determine the required adjustment position of the mold limiting clamp 8 based on the size of the cement sample to be tested. Manually loosen the butterfly bolt 11 to disengage it from the threaded opening 14 on the mold support platform 6. At this point, the moving frame 9 moves along the slide rod 16. Then, push the moving frame 9; under the action of the sliding component, the moving frame moves along the width direction of the mold support platform 6. When the mold limiting clamp 8 is adjusted to a suitable position to effectively limit and fix the mold, stop moving the moving frame 9. Pass the butterfly bolt 11 through the through hole of the mounting plate 10 and thread it into the corresponding threaded opening 14 on the mold support platform 6. Manually tighten the butterfly bolt to lock the position of the moving frame 9. Then, place the cement mold on the mold support platform 6, ensuring that both sides of the mold are tightly fitted with the mold limiting clamp 8. The mold limiting clamp securely fixes the mold, preventing it from shifting during vibration.

[0035] Then, the cover 1 of the cement mortar vibrating table is closed, and the main body 4 of the cement mortar vibrating table is started. After receiving the vibration energy, the vibration table surface 5 evenly transmits it to the mold support platform 6, which is coaxially fixed on it. The mold support platform 6 then drives the mold placed on it and fixed by the mold limiting clamp 8 to vibrate synchronously. Under the action of periodic vibration, the gaps between the cement mortar particles in the mold are continuously squeezed and filled, and the cement mortar gradually becomes dense, providing a guarantee for the accurate subsequent testing of cement strength.

[0036] Among them, the cement mortar vibrating table body 4 is a common device in this field. Its working principle is as follows: The synchronous motor inside the cement mortar vibrating table body 4 is the source of vibration energy. When the motor starts, its output shaft drives the cam to rotate. During the rotation of the cam, due to the irregularity of its contour, a periodic eccentric force is generated. This force is transmitted to the horizontally installed vibrating table surface 5 through the vibration output end of the vibrating table body.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
