Description

Technical Field

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

[0002] As the country continues to develop and grow stronger, many buildings have begun to be constructed in various regions. The most important considerations when constructing buildings are the strength and safety of the building structure. Cement of different strength grades has different strengths, and it is usually necessary to prepare test specimens and conduct multiple strength tests. When preparing test specimens, cement mortar needs to be poured into a mold, and a vibrating table is used to make the mortar evenly fill the mold. After the mortar has cured, it is demolded to obtain the test specimen. However, existing mortar vibration tables can only apply a single vertical vibration force to the mold on the vibration platform during use. Since some molds have complex internal cavity shapes and internal corners, the use of a single vertical vibration force cannot effectively fill all corners of the mold with mortar. This results in voids inside and on the surface of the demolded specimen. These voids directly affect the structural strength of the specimen and thus interfere with the accuracy of the specimen strength test results. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Example 1 Reference Figure 1-3 This is the first embodiment of the present invention, which provides a mortar compaction table. The mortar compaction table includes a base plate 1, a top plate 11 above the base plate 1, springs at the four corners of the base plate 1, the base plate 1 and the top plate 11 are connected by springs, a guide cylinder 1 is provided at the four corners of the base plate 1, the spring is provided inside the guide cylinder 1, a guide cylinder 2 is provided at the four corners of the top plate 1, the guide cylinder 2 is slidably inserted into the guide cylinder 1, the end of the spring away from the base plate 1 is connected to the top plate 11, a cleaning unit 2 is provided on one side of the base plate 1, and a vibration unit 3 is provided on the upper surface of the base plate 1. The vibration unit 3 includes a swing seat 31, a swing hammer 32 is hinged on the swing seat 31, a roller array is provided at one end of the swing hammer 32, the roller is rotatably connected to the swing hammer 32, and the swing seat 31 is fixedly provided on the upper surface of the base plate 1. A vibration platform 12 is slidably mounted on the upper surface of the top plate 11, a contact plate 13 is mounted on the lower surface of the vibration platform 12, a limit plate 14 is mounted on the lower surface of the top plate 11, and a spring piece 15 is mounted between the contact plate 13 and the limit plate 14. The swing hammer 32 can contact the contact plate 13 during the swinging and shifting process. A linear groove is symmetrically mounted on the upper surface of the top plate 11, and a linear rail is mounted on the lower surface of the vibration platform 12. The linear rail is slidably mounted in the linear groove. An avoidance groove is opened in the middle of the top plate 11, and the contact plate 13 passes through the avoidance groove. One end of the spring piece 15 is connected to the contact plate 13, and the other end is connected to the limit plate 14.

[0018] The vibration unit 3 includes a base 33, an eccentric wheel 34 is mounted on the base 33, a connecting rod 35 is mounted on the eccentric wheel 34, one end of the connecting rod 35 is hinged to the eccentric part of the eccentric wheel 34, the base 33 is mounted on the upper surface of the base plate 1, and a motor is mounted on the base 33. The motor is located on the side of the base 33 away from the eccentric wheel 34, and the output shaft of the motor passes through the base 33 and is coaxially connected to the eccentric wheel 34.

[0019] A fixed seat 36 is provided on the base plate 1, and a movable rod 37 is slidably provided on the fixed seat 36. One end of the movable rod 37 is hinged to the end of the connecting rod 35 away from the eccentric wheel 34. The fixed seat 36 is provided on the upper surface of the base plate 1.

[0020] The end of the moving rod 37 away from the connecting rod 35 is connected to the swing hammer 32, the middle part of the swing hammer 32 is connected to the swing seat 31, and the moving rod 37 is hinged to one end of the swing hammer 32.

[0021] During use, first place the mold containing mortar on the vibration platform 12, and then start the motor. When the motor starts, the motor output shaft rotates and drives the eccentric wheel 34 to rotate. When the eccentric wheel 34 rotates, it will pull the connecting rod 35. The displacement of the connecting rod 35 will pull the moving rod 37. At this time, the moving rod 37 will reciprocate linearly. During the reciprocating movement of the moving rod 37, the moving rod 37 will pull the swing hammer 32. The swing hammer 32 will then swing back and forth around the connection point between it and the swing seat 31 as the axis. Then the swing hammer 32 will contact and push the top plate 11 and the vibration platform 12 to rise vertically. At the same time, the swing hammer 32 will also contact the contact plate 13 and push the contact plate 13 and the vibration platform 12 to move linearly. At this time, the spring piece 15 deforms. When the swing hammer 32 swings until it separates from the top plate 11 and the vibration platform 12, the top plate 11 and the vibration platform 12 will descend under the action of the spring force and gravity. At this time, the mortar inside the mold will be subjected to a vertical vibration force. As the swing hammer 32 gradually moves to reset, it no longer applies a pushing force to the contact plate 13. At this time, the vibration platform 12 is reset under the reset elastic force of the spring plate 15. During this process, the vibration platform 12 will move laterally linearly, thereby causing the mortar in the mold to be subjected to a lateral force.

[0022] Example 2 Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: A hopper 16 is provided on one side of the top plate 11, and a water spray plate 17 is provided on the side of the top plate 11 away from the hopper 16. Spray nozzles 18 are arranged in an array on the water spray plate 17, and the water outlet direction of the spray nozzles 18 is inclined downward.

[0023] The cleaning unit 2 includes a cleaning box 21, which is equipped with a partition 22 that divides the interior of the cleaning box 21 into a collection tank 23 and a clean water tank 24. A water pipe 25 is installed on the cleaning box 21, with one end of the water pipe 25 away from the cleaning box 21 connected to the spray plate 17 and communicating with it internally. The cleaning box 21 is located at the lower end of the hopper 16, and the position of the collection tank 23 corresponds to the discharge direction of the hopper 16. The partition 22 is provided with an array of filter holes. The water pipe 25 is internally connected to the clean water tank 24. A water pump is installed at the connection between the water pipe 25 and the cleaning box 21. Water in the clean water tank 24 can enter the water pipe 25 under the action of the water pump, and then enter the spray plate 17 through the water pipe 25, and finally be sprayed out by the nozzle 18.

[0024] During use, in order to ensure that the mortar can be fully filled in the mold, an appropriate amount of excess mortar needs to be added to the mold. Before the mortar is compacted, the mortar will accumulate above the mold. During vibration, some of the mortar in the mold will seep out of the mold and fall onto the vibration platform 12 under the action of vibration force. At this time, the water in the cleaning box 21 is pumped into the water pipe 25 by the water pump, and then the water enters the spray plate 17 through the water pipe 25. Finally, the water in the spray plate 17 is sprayed out by multiple nozzles 18. When water is sprayed from nozzle 18, it washes the mortar on the vibrating platform 12. Under the action of lateral vibration, the water and mortar move towards the hopper 16 and then enter the collection tank 23. After entering the collection tank 23, the water enters the clean water tank 24 through the filter holes on the partition 22, while the sand and gravel are filtered in the collection tank 23. The water entering the clean water tank 24 is sprayed out again from nozzle 18 by the water pump, and the cycle continues.

[0025] The remaining structure is the same as that in Example 1.
