Description

TECHNICAL FIELD

[0001] The utility model relates to a steel structure surface shot blasting cleaning equipment. BACKGROUND

[0002] Steel structure is an indispensable basic component for many large projects due to its high strength, good plasticity and relatively light weight. However, the surface of the steel structure is easily contaminated with various impurities during its processing, transportation and storage. For example, after cutting and welding, the steel structure may have residual oxide scale and welding slag. During transportation, dust and soil may be attached due to environmental factors. If the environment is humid, the surface may also rust. If these impurities are not removed, they will not only affect the appearance of the steel structure, but also seriously weaken its performance.

[0003] However, in the prior art, manual polishing tools are used for cleaning, which is extremely inefficient. Although chemical pickling can remove some impurities such as oxide scale, it has some disadvantages. On the one hand, the strong acid solution used in the pickling process is highly corrosive and can cause personal injury to the operator if not handled properly. It also causes serious pollution to the surrounding environment of the equipment. The cost of subsequent waste liquid treatment is high. In addition, pickling may excessively corrode the surface of the steel structure, change the microstructure of the steel structure, reduce its original mechanical properties, and cause the steel structure to be more prone to fatigue damage during use. Both methods have significant drawbacks. SUMMARY

[0004] The utility model discloses a steel structure surface shot blasting cleaning equipment to solve the prior art problems.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

The grid 37 is located in the middle of the fan wheel 36 and has two... The other end of the drive shaft 34 is fixedly connected to the drive shaft 34. The other end of the drive shaft 34 is connected to the stepper motor 31 via the belt drive assembly 32. The end of the shot inlet pipe 39 extends to the middle of the fan wheel 36. The fan wheel 36 is located inside the protective shell 38. The protective shell 38 is fixedly connected to the inner side of the outer shell 35. The outer shell 35 is fixedly connected to the upper side of the cleaning chamber 1, and the lower end of the outer shell 35 extends into the interior of the cleaning chamber 1. The shot inlet pipe 39 is fixedly connected to the middle of one side of the outer shell 35. The drive shaft 34 is rotatably mounted on the other side of the outer shell 35 via a bearing.

[0023] The specific settings and functions of this embodiment are described below: The feeding mechanism 4 drives the steel structure to move slowly, and the stepper motor 31 is started. The output shaft of the stepper motor 31 drives the transmission shaft 34 to rotate through the belt transmission assembly 32.

The shot is continuously replenished into the receiving bin 33 and enters the shot inlet pipe 39. The column grid 37 rotates in the shot inlet pipe 39, throwing some of the shot out from the slot of the shot inlet pipe 39.

The double sprocket set 46 is fixedly connected to the other end of the central shaft 44. Two adjacent sets of double sprocket sets 46 are connected by a chain 47.

[0025] The overall effect of this embodiment is that by controlling the start of the reduction motor 41, the output shaft of the reduction motor 41 drives the directly connected central shaft 44 to rotate, thereby driving the feeding roller 43 to rotate. At the same time, the central shaft 44 drives the double sprocket set 46 to rotate. Under the transmission action of a set of chains 47, the adjacent central shaft 44 is driven to rotate. This transmission continues in sequence, with multiple sets of central shafts 44 driving multiple sets of feeding rollers 43 to rotate.
