Abstract
The utility model provides a road and bridge construction mixer damping device, this damping device are fixed in the (mixing) shaft top, and it adopts rubber arm and balancing weight, can effectively alleviate the vibration of (mixing) shaft according to its heavy burden of working strength adjustment, promotes motor life.
Description
Technical Field
The utility model relates to a construction machinery technical field specifically is a road bridge construction mixer damping device.
Background
The concrete in the road and bridge engineering construction is widely applied as a basic building material, and is called as concrete for short: the concrete is cement concrete which is prepared by mixing cement as a cementing material and sand and stone as an aggregate with water (which may contain an additive and an admixture) according to a certain proportion and stirring, is also called common concrete and is widely applied to civil engineering such as road and bridge construction, inorganic cementing materials such as cement, lime, gypsum and the like are mixed with water to enable concrete mixtures to have plasticity, and then various concretes are subjected to setting and hardening through chemistry and physical chemistry to generate strength, when the concrete is prepared, firstly, raw materials are reasonably selected and the mixing proportion is determined according to the requirements of engineering on workability, strength, durability and the like to achieve the purpose of economy and applicability, the preparation of the concrete needs to stir the raw materials, while the existing stirring barrel works, because the stirring resistance is large, the power of the adopted motor is usually several kilowatts, the stirring shaft is easy to generate vibration because of self-work, and because concrete is attached to the stirring shaft, the stirring shaft is easy to generate resonance in stirring, the machine can shift because of vibration, the service life of the motor can be influenced because of vibration, and the construction process is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the utility model provides a road and bridge construction mixer damping device, this damping device are fixed in the (mixing) shaft top, and it adopts rubber arm and balancing weight, can effectively alleviate the vibration of (mixing) shaft according to its heavy burden of working strength adjustment, promotes motor life.
The utility model adopts the technical proposal that: the utility model provides a road and bridge construction mixer damping device, this damping device bilateral symmetry respectively are equipped with one fan head (4), go up through rubber arm (3) of threaded connection on every fan head (4), connect through stainless steel branch (2) between two rubber arms (3), stainless steel branch (2) on set up threaded hole (1), screw hole (1) be used for connecting external screwed joint (10) on (mixing) shaft (9), screw hole (1) screw in external screwed joint (10) after fixed with fastening bolt. The fan head (4) is further provided with an arc-shaped resistance reducing sheet (8), and the arc-shaped resistance reducing sheet (8) is made of rubber materials with smooth surfaces and used for throwing away concrete adhered to the arc-shaped resistance reducing sheet.
Furthermore, the fan head (4) is further provided with a balancing weight base (7), the balancing weight base (7) is provided with a convex shoulder, the convex shoulder is provided with an external thread rod (5), the balancing weight (6) with internal threads is screwed into the external thread rod (5), and the balancing weight (6) is screwed and fixed through a screwing piece (11).
The utility model has the advantages that: the utility model provides a road and bridge construction mixer damping device, this damping device are fixed in the (mixing) shaft top, and it adopts rubber arm and balancing weight, can effectively alleviate the vibration of (mixing) shaft according to its heavy burden of working strength adjustment, promotes motor life.
