A flip-type dust-proof tire breaker

Abstract

The invention relates to a turnover plate type dustproof tire puncturing device. The turnover plate type dustproof tire puncturing device is characterized by comprising a connecting triangular hollow block, a horizontal plate, barbs, a reinforcing rib plate, an electric push rod, a supporting triangular hollow block, a bottom plate, bearing seats, a force releasing base, a cross plate and a connecting plate; the lower parts of the connecting triangular hollow block and the supporting triangular hollow block are symmetrically fixed on two sides of the bottom plate; the upper parts of the connecting triangular hollow block and the supporting triangular hollow block are connected with the horizontal plate; the barbs are mounted on the bottom plate through the bearing; the bottom plate is an oblong steel sheet; in a length direction of the tire puncturing device, a water drain groove is formed in one side of the bottom plate, and a plurality of bearing seat mounting holes are formed in the other side of the bottom plate; four bearing seat mounting holes form one group; each group of bearing seat mounting holes is distributed in the length direction of the tire puncturing device in an equally spaced manner; two bearing seats are mounted on one group of bearing seat mounting holes; one barb is mounted between the two bearing seats; and a force releasing base mounting groove is formed in the middle of the external side of each group of bearing seat mounting holes.

Description

technical field [0001] The invention relates to the technical field of tire breaking, in particular to a flap-type dust-proof tire breaking device. Background technique [0002] The tire breaker, also known as road barricades and barbed barricades, is a tire-breaking type of vehicle-blocking barricades, which are now widely used in government agencies, prisons, police stations, schools, etc. The road thorn can penetrate the tire within 0.5 seconds and release the gas in the tire through the vent hole, so that the vehicle cannot move forward. It is a very effective security device. The tire breaker can be divided into buried type and surface type according to the installation position. The buried type needs to be excavated before installation, resulting in an increase in time and cost; while the surface type tire breaker is installed on the ground, which is suitable for many occasions. etc. are flexible, so the surface tire breaker has gradually become the mainstream of the ...

AI Technical Summary

Problems solved by technology

The disadvantages of the above two patents are as follows: 1. When the tire breaking device is not working, it is impossible to prevent dust, stones, etc. from entering the inside of the tire breaking device, and the tire breaking device cannot be raised when the tire is compacted by the vehicle tires. ; 2. The anti-collision performance of the tire breaker is poor, and it is easy to break the main shaft; 3. The cost of using hydraulic cylinders or electromagnetic devices is high and the requirements for the working environment are high
