Description

Technical Field

[0001] The utility model belongs to the technical field of vibration tables, and particularly relates to a leveling mechanism of a vibration test table. Background Technique

[0002] The leveling mechanisms of vibration tables are mostly fixedly arranged on the vibration tables, which are inconvenient to disassemble and assemble when not in use, and additional mechanisms are required to control during the leveling operation, increasing the use cost. Content of the Utility Model

[0003] The purpose of the utility model is to provide a leveling mechanism of a vibration test table to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a leveling mechanism of a vibration test table, the leveling mechanism is detachably installed on the first clamping plate or the second clamping plate, and the first clamping plate and the second clamping plate are used for clamping a mold;

[0005] Driving mechanisms are arranged on the sides of the first clamping plate and the second clamping plate, and the driving mechanisms drive the first clamping plate and the second clamping plate to move towards or away from each other.

[0006] It should be noted in the solution that the leveling mechanism includes a tension spring, a slider, a fixed pipe and a first spring. The tension spring is arranged in the connection groove of the first clamping plate or the second clamping plate. The lower end of the tension spring is fixedly connected to the bottom of the connection groove, and the upper end of the tension spring is fixedly connected to the lower part of the slider for restricting the position of the slider.

[0007] Further, it is worth noting that a guiding column is fixedly arranged inside the connection groove. The guiding column is slidably connected with the slider and penetrates through the slider for restricting the moving direction of the slider.

[0008] Furthermore, it should be noted that the fixed pipe is a tubular structure with one end open. The other end of the fixed pipe is threadedly connected with the slider. The first spring is arranged inside the fixed pipe. One end of the first spring is connected to the inside of the fixed pipe. The other end of the first spring is connected with a connecting rod. One side of the connecting rod is slidably connected to the inside of the fixed pipe. The other end of the connecting rod is fixedly provided with a scraping strip.

[0009] Compared with the prior art, the leveling mechanism of a vibration test table provided by the utility model has at least the following beneficial effects:

[0010] Detachably installing the leveling mechanism on the clamping plate has two advantages. One is that it is convenient to disassemble when not in use, and the other is that the driving mechanism of the clamping plate can be used as a power source, reducing costs. Description of the Drawings

[0015] Please refer to Figures 1-4 , the present utility model provides a leveling mechanism for a vibration test bench.

[0016] The leveling mechanism 4 is detachably installed on the first clamping plate 302 or the second clamping plate 303. When the vibrating table is used for ramming sand and gravel concrete, the leveling mechanism 4 levels the sand and gravel concrete. The vibrating table body includes a base 101 and an installation table 104. Two clamping plates are slidably connected to the installation table, and driving mechanisms 2 are installed on both sides of the clamping plates, which can be replaced by hydraulic cylinders. The driving mechanisms 2 drive the first clamping plate 302 and the second clamping plate 303 to move towards or away from each other, so as to clamp or loosen the mold.

[0017] The leveling mechanism 4 includes a tension spring 404, a slider 403, a fixed tube 405 and a first spring 408. The tension spring 404 is arranged in the connection groove 401 of the first clamping plate 302 or the second clamping plate 303. The lower end of the tension spring 404 is fixedly connected to the bottom of the connection groove 401. The upper end of the tension spring 404 is fixedly connected to the lower part of the slider 403 for restricting the position of the slider 403. A guide post 402 is fixedly arranged inside the connection groove 401. The guide post 402 is slidably connected to the slider 403 and penetrates through the slider 403 for restricting the moving direction of the slider 403. The fixed tube 405 is a tubular structure with one end open. The other end of the fixed tube 405 is threadedly connected to the slider 403. The first spring 408 is arranged inside the fixed tube 405. One end of the first spring 408 is connected to the inside of the fixed tube 405. The other end of the first spring 408 is connected to a connecting rod 406. One side of the connecting rod 406 is slidably connected to the inside of the fixed tube 405. The other end of the connecting rod 406 is fixedly provided with a scraping strip 407.

[0018] When the vibration table body 1 is used as sand, gravel and concrete in the ramming mold, the vibration ramming operation part is the same as the above vibration test operation steps. Connect the fixed pipe 405 and the slider 403 by thread, and pull the slider 403 upward along the guide post 402. Under the limiting action of the tension spring 404 and the limit of the mold height, the fixed pipe 405 can be fitted and connected to the upper part of the mold, and it can be applied to molds of different heights. When the first clamping plate 302 and the second clamping plate 303 perform the clamping operation, the scraping strip 407 and the connecting rod 406 squeeze the first spring 408 inside the fixed pipe 405 under the limiting action of the slider 403, which can be applied to molds of different widths, and at the same time can push off the excess sand and gravel. When the limit on the mold is released after the vibration ramming operation is completed, the first clamping plate 302 can drive the limiting mechanism 305 and the limiting mechanism 306 to level the part of the sand and gravel shaken out.
