Description

Technical Field

[0001] This utility model relates to the field of building testing equipment technology, specifically a mortar compaction table for cement testing in highway engineering. Background Technology

[0002] In highway engineering, in order to ensure the quality of highway construction, it is necessary to conduct quality testing on the cement mortar used in its construction. This is done by making corresponding test specimens, storing the specimens in a designated environment for setting, and then testing their quality after setting. During the specimen making process, a special mortar compaction table is usually used for compaction.

[0003] Traditional mortar vibratory compaction tables are quite long, mainly because they have internal horizontal stabilizing rods for positioning. One end of the stabilizing rod is hinged to the inside of the box, and the other end is connected to the vibratory specimen. This ensures that the vibratory specimen can move vertically up and down and prevents tilting. However, this makes the overall size of the mortar vibratory compaction table too large and difficult to carry. At the same time, due to its fixed design, the vertical movement of the specimen is fixed during the vibration process and cannot be adjusted to meet the requirements. Therefore, a mortar vibratory compaction table for cement testing in highway engineering is provided to solve the above problems. Utility Model Content

[0004] This utility model provides a mortar vibration table for cement testing in highway engineering, which solves the problems of existing mortar vibration tables being large and difficult to carry, and having a fixed range of vertical movement of the specimen during vibration, which cannot be adjusted to meet specific needs.

[0011] Preferably, the device housing has a built-in upward drive component, which is connected to the adjustment component via a transmission connection.

[0012] Preferably, the upward driving component includes;

[0013] Two sets of protrusions are symmetrically arranged on both sides inside the equipment box, and when the protrusions rotate, they abut against the bottom of the adjusting component to push the adjusting component to move upward.

[0022] This utility model discloses a mortar compaction table for cement testing in highway engineering, which has the following beneficial effects: During use, the convex block rotates, pushing the adjusting component upward, causing the sliding contact plate to move upward along the T-shaped axis, compressing the compaction spring, and driving the material tray upward. As the convex block continues to rotate, it eventually disengages from the adjusting component. At this time, under the action of the compaction spring, the sliding contact plate is pushed to fall rapidly, thereby compacting the specimen on the material tray. Furthermore, by adjusting the length of the adjusting component extending outward from both ends of the sliding contact plate, the height of the sliding contact plate when the convex block disengages from the adjusting component is changed, thereby changing the vertical movement range of the compaction. At the same time, by replacing the traditional stabilizer bar with the T-shaped shaft, the overall size is smaller and easier to carry. Attached Figure Description

[0029] This application provides a mortar vibration table for cement testing in highway engineering, which solves the problems of existing mortar vibration tables being large and difficult to carry, and having a fixed range of vertical movement of the specimen during vibration, which cannot be adjusted to meet specific needs.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This utility model discloses a mortar vibrating table for cement testing in highway engineering.

[0032] Example 1

[0033] According to the appendix Figure 1-4 As shown, it includes an equipment box 1, and an improved vibration compaction mechanism 2 is provided inside the equipment box 1. The improved vibration compaction mechanism 2 includes:

[0034] T-shaped shaft 21 is fixedly installed at the bottom of the equipment box 1;

[0035] The sliding contact plate 22 is slidably disposed on the outer surface of the T-shaped shaft 21;

[0036] The vibrating spring 23 is movably sleeved on the outer surface of the upper end of the T-shaped shaft 21, and its bottom end abuts against the top of the sliding contact plate 22.

[0037] The material tray 25 is fixedly mounted on the top of the sliding contact plate 22;

[0038] Adjustment component 27, which is telescopically mounted at both ends of sliding contact plate 22, is used to change the height at which sliding contact plate 22 is pushed upward.

[0039] The equipment box 1 has an internal push-up drive 3, which is connected to the adjustment component 27 via a transmission.

[0040] The upward drive component 3 includes two sets of protrusions 31, which are symmetrically arranged on both sides inside the equipment box 1. When the protrusions 31 rotate, they abut against the bottom of the adjusting component 27 to push the adjusting component 27 to move upward.

[0041] The outer surface of the adjusting component 27 is provided with a plurality of equidistant positioning holes 28, and the adjusting component 27 is fixedly installed to the sliding contact plate 22 through the positioning holes 28.

[0042] A silent support platform 14 is fixedly installed at the bottom of the equipment box 1, facing the sliding contact plate 22, and a silent cover 12 is rotatably installed on the top of the equipment box 1.

[0043] A connecting column 24 is fixedly installed between the bottom of the material pallet 25 and the sliding contact plate 22, and the connecting column 24 penetrates the top surface of the equipment box 1.

[0044] A mounting column is fixedly installed on the top of the material tray 25, and a specimen fixing frame 26 is fixedly installed on the outer surface of the mounting column by nuts.

[0045] A control switch 13 is fixedly installed on the outer surface of the equipment box 1, and the control switch 13 is connected to the servo motor 32 for control.

[0046] In this embodiment, the device incorporates a modified vibration compaction mechanism 2. During use, the upward drive component 3 is activated, causing the two sets of protrusions 31 to rotate. At this point, the protrusions 31 rotate to a position below the adjusting component 27. As the protrusions 31 rotate, they push the adjusting component 27 upward, causing the sliding contact plate 22 to move upward along the T-shaped shaft 21. This compresses the vibration spring 23, and simultaneously, the connecting column 24 drives the material tray 25 to move upward. As the protrusions 31 continue to rotate, they eventually disengage from the adjusting component 27. At this point, under the action of the vibration spring 23, the sliding contact plate 22 is pushed to fall rapidly, thereby compacting the specimen on the material tray 25. Furthermore, by adjusting the length of the adjusting component 27 extending outward from both ends of the sliding contact plate 22, the height of the sliding contact plate 22 when the protrusions 31 disengage from the adjusting component 27 is changed, thus altering the vertical movement range of the vibration. Additionally, by replacing the traditional stabilizing rod with the T-shaped shaft 21, the overall size is reduced, making it easier to carry.

[0047] Example 2

[0048] According to the appendix Figure 1-4 As shown, based on Embodiment 1, more specifically, the upward drive component 3 also includes a servo motor 32, two sets of transmission gears 33, and a transmission chain 34. The servo motor 32 is fixedly installed inside the equipment housing 1. The two sets of transmission gears 33 are respectively fixedly installed on a set of protrusions 31 and the end of the output shaft of the servo motor 32, and the two sets of transmission gears 33 mesh with each other. The transmission chain 34 is installed between the output end of the servo motor and another set of protrusions 31. In actual assembly, sprockets are installed at both ends of the transmission chain 34. The two sets of sprockets are respectively fixedly installed on a set of protrusions 31 and the end of the output shaft of the servo motor 32. The two sets of sprockets are the same size. Therefore, when the servo motor 32 is started, the angular velocities of the two sets of sprockets are the same. The transmission gears 33 on the output shaft of the servo motor 32 are coaxially installed with the sprockets. Therefore, the angular velocities of the transmission gears 33 and the sprockets are the same, thereby realizing that the two sets of protrusions 31 rotate at the same angular velocity.

[0049] In this embodiment, by starting the servo motor 32, the servo motor 32 drives a set of protrusions 31 to rotate synchronously in the opposite direction to the output shaft of the servo motor 32 through two sets of transmission gears 33. At the same time, the transmission chain 34 drives another set of protrusions 31 to rotate synchronously in the same direction as the output shaft of the servo motor 32, so that the two sets of protrusions 31 can maintain the same rotation speed and frequency.
