Description

Raceway repairing mechanism and concrete mixing and transporting car
Technical field
The present invention relates to engineering machinery field, particularly relate to a kind of raceway repairing mechanism and concrete mixing and transporting car.
Background technology
Concrete mixing and transporting car (hereinafter referred to as trucd mixer) be by ready-mixed concrete from mixing plant safe, reliable, efficient be transported to the special-purpose vehicle of building site, form primarily of automobile chassis, mixing drum, drive system, water system, operating system, discharging system, subframe and protector.Wherein mixing drum accumbency is on automobile chassis, forms supported at three point by reductor, two riding wheel apparatus.
Raceway is the annular construction member of boring after being welded on mixing drum, and be the roller contact of the rear supports of mixing drum, raceway and two riding wheel apparatus, form rolling bearing, when mixing drum rotates under the drive of reductor, raceway rolls on the roller of two riding wheel apparatus.In the ideal situation, raceway and roller are at the initial stage of use, the friction surface of raceway should be bright, but the defect because working service is lack of standardization, in manufacture process and the reason such as applying working condition is severe, the friction surface of raceway there will be the defects such as peeling, scuffing and groove, affects concrete-agitating effect and even threatens traffic safety.
At present in the raceway repairing wearing and tearing, mainly contain following three kinds of modes.
First kind of way adopts sanding machine to carry out manual polishing reparation.Which is without the need to dismantling mixing drum, and operative employee needs hand polishing machine to stand on the cat ladder of mixing drum both sides to polish to raceway.Because the fix tools such as sanding machine need be energized use, therefore, first this kind of mode require that operating environment has external power supply; Secondly repairing effect relies on level and the qualification of workman completely, requires higher, the poor stability of repairing effect to craftsmanship; Operation process relies on manually carry out completely again, and efficiency is not high, and labor strength is large.
The second way carries out machined reparation after mixing drum entirety being unloaded.Pulling down whole mixing drum due to needs is placed on renovation machine, needs to be equipped with several dismounting workman, and the amount of labour is large, and human cost is high.In addition, if the repair of trucd mixer in service radius need be met, this kind of machining apparatus and reparation mounting platform need circulation transport, but excessive prosthetic appliance and platform not only increase cost of transportation, and increase the cost repeating to manufacture, this is obviously unfavorable for that this demand for development falls in enterprise, also can not meet the requirement of after-sales maintenance service maneuverability.
The third mode replaces new raceway.Weld together owing to boring after raceway and mixing drum, more renew raceway and first the raceway of serious wear will be got off from gas cutting mixing drum, then change new raceway, then raceway and mixing drum are welded together.This repair mode cost is high, and has damage to mixing drum, and cannot ensure that raceway is concentric with mixing drum, has a strong impact on the normal use of user.
