Chiseling machine for tunnel top surface layer with airflow mutual-contacting and anti-splashing

Abstract

The invention discloses a chiseling machine for a tunnel top surface layer with airflow mutual-contacting and anti-splashing. The structure of chiseling machine for the tunnel top surface layer with airflow mutual-contacting and anti-splashing comprises: a chiseling device, a driving host, a moving wheel, a hand push rod and an operation switch. The chiseling machine for the tunnel top surface layer with airflow mutual-contacting and anti-splashing has the beneficial effects that the chiseling head arranged on the attack mechanism can rotate independently, so that larger stones are subjected to rotary crushing, the surrounding soil layers are not influenced, the chiseling head is prevented from generating large impact force when being contacted with the stones due to the fixed structure, the reinforced concrete protective layer at the periphery of the chiseling head is damaged, airflow generated by fast rotation of the rotating rod is collected and utilized by utilizing the aerodynamicprinciple, the airflow pressure is increased under the structure of the airflow hopper and is output through the air outlet, the external expanded airflow generated by the attack mechanism is subjected to convection, the strength of the external expanded airflow is weakened, and meanwhile, crushed stones splashed along with the attack mechanism are resisted, thereby effectively avoiding the userfrom being injured by the external splashing due to larger airflow force.

Description

technical field [0001] The invention relates to the field of concrete engineering construction equipment, more precisely, it relates to a chisel machine for the surface layer of the top of a tunnel in which the airflow resists and splashes each other. Background technique [0002] With the rapid development of the city, more and more people are pouring into the city to work, which leads to dense population and serious traffic congestion in the city. Therefore, in recent years, the construction of tunnels has gradually become the mainstream in the transportation industry. It is developed underground, so its construction has strict standards, and it needs regular maintenance. When repairing the top surface of the tunnel, a concrete chisel machine is usually used to chisel the surface. Increase the bonding force between the new and old joint surfaces of concrete to ensure that the concrete pouring forms a whole. However, when this kind of concrete roughing machine encounters la...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a chisel machine for the top surface of the tunnel with airflow resisting and splashing each other, so as to solve the problem in the prior art that when larger stones are encountered, the collision with the stones will A large impact force is generated, so that during the crushing process of the stone, it splashes around due to the large force, causing the user to be injured. The surrounding soil layer will be affected to a certain extent, causing the original structural material to be destroyed, thereby affecting the protective layer of reinforced concrete, and causing catastrophic damage if it is serious
