Abstract

The invention belongs to the technical field of concrete processing equipment, and relates to a vibrating bar of a tunnel trolley. The vibrating rod comprises a cylindrical rod body. A vibrating assembly is arranged in the rod body. The vibrating rod is characterized in that a vibration reduction connecting assembly is arranged at the upper end of the rod body, the vibration reduction connecting assembly comprises two symmetrically-arranged connectors, the connector at the lower end is fixed to the upper end of the rod body, and the two connectors are connected through an elastic vibration reduction sleeve. Compared with the prior art, the vibrating bar of the tunnel trolley has the advantages that 1, the design is reasonable, the structure is compact, and the vibration amplitude is guaranteed; 2, the sealing performance is good, and the normal work of the vibrating rod can be guaranteed; and 3, the cooling is reliable, and the vibrating bar can operate for a long time.

Description

technical field [0001] The invention belongs to the technical field of concrete processing equipment, and relates to a vibrating rod for a tunnel trolley. Background technique [0002] When mixing the concrete components with a concrete mixer, the air bubbles must be removed. The use of vibrating rods for tamping can make the concrete densely combined, eliminate the phenomenon of concrete honeycomb pockmarks, etc., so as to improve its strength and ensure the quality of concrete components. The existing vibrating rod is installed on the frame to vibrate the concrete during use, but because the vibrating rod is directly fixed on the frame, the vibration amplitude is reduced, and the vibration amplitude cannot be further improved, even if the vibration amplitude is forcibly increased. It will cause damage to the rack and its components, and the noise will be louder. [0003] For example, Chinese patent literature discloses a concrete vibrating rod [application number: 201721...
