Abstract

The invention relates to the technical field of concrete vibrators, and discloses a concrete vibrator for prefabricated building assembly, hydraulic sleeves are uniformly mounted on the side wall of a vibration groove, the outer end parts of the hydraulic sleeves are movably sleeved with chucks, a movable groove is formed in the middle of the bottom surface of a vibration table, and a vibration motor is fixedly mounted at the bottom of a mounting block; a sleeve rod is fixedly mounted at the position, located at the bottom of the sleeve hole, of the top of the base, the top of the sleeve rod is sleeved with the sleeve hole, a sliding plate is movably sleeved with the adjusting cavity, a first electric control valve is fixedly mounted in the middle of the sliding plate, a transmission gear is movably mounted in the transmission groove, and a gear ring meshed with the transmission gear is arranged on the outer ring of the mounting block; a rotary column is movably installed in the limiting cavity, a communicating hole is formed between the adjusting cavity and the limiting cavity, a second electric control valve is fixedly installed in the middle of the communicating hole, and the vibration table is stable and uniform in vibration force on the prefabricated part formwork and good in vibration effect.

Description

technical field [0001] The invention relates to the technical field of concrete vibrators, in particular to a concrete vibrator for prefabricated building assembly. Background technique [0002] The prefabricated building is a building that transfers a large number of on-site operations in the traditional construction method to the factory, processes the prefabricated parts in the factory, transports it to the building construction site, and assembles and installs it on site through a reliable connection method. The most important thing is to finish pouring the prefabricated parts in advance, and when the prefabricated parts are poured, in order to make the internal air bubbles escape, a vibrator needs to be used to vibrate. The concrete is fully mixed, but the existing vibrating table still has certain shortcomings: [0003] The vibrating table is composed of a base and a table, which are connected together by a vibration spring, and a vibration motor is installed at the b...

AI Technical Summary

Problems solved by technology

[0003] The vibrating table is composed of a base and a table, which are connected together by vibrating springs, and a vibration motor is installed at the bottom of the table to drive its vibration. When working, place the prefabricated template that needs to be vibrated on the table, and then Start the vibration motor to vibrate it, but the prefabricated parts are placed directly on the general vibrating table, so it is easy to cause the prefabricated part template to slide randomly on the table when vibrating. On the one hand, it affects the quality of vibration, resulting in poor vibration effect. Even, it is easy to cause the concrete inside the formwork to be thrown out. On the other hand, it also causes the vibrating table to tilt, because the vibrating table and the base are connected by spring support, so that once the position of the prefabricated part slides to one side, it will cause If the table top is tilted, it is more likely to cause the concrete to be vibrated onto the table top, affecting the vibration effect;

[0004] At the same time, when the vibrating table is used to vibrate the preform, the vibrating table will not be moved after the motor is started, and the vibrating motor generates vibration force through the rotation of the internal eccentric block and then acts on the vibrating table, but due to the vibration The position of the motor is fixed, and the formwork of the prefabricated part is basically rectangular, but its length and width are often very different, so that the vibration force of different sections of the prefabricated part is different during vibration, and it cannot be adjusted. , so it will cause poor quality of the vibration, resulting in more holes in the local area and low structural strength
