Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, in particular to a spraying device for anti-corrosion treatment of the surface of a steel structure in construction. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields. Since steel structures are prone to rust, spraying devices are often used to treat their surfaces for corrosion protection during steel structure production and processing to extend the service life of the steel structure. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN217911021U discloses a steel structure surface anti-corrosion treatment equipment, wherein a reciprocating screw is rotatably installed in the bracket one, one end of the reciprocating screw penetrates and extends out of the bracket one, a motor is installed on the right side of the bracket one, the output shaft of the motor is fixedly connected to the reciprocating screw, two Z-shaped slide seats are threadedly installed on the reciprocating screw, and a fixing assembly is arranged on the slide seat. When the steel structure is sprayed, in order to ensure that the steel structure used in different environments has sufficient corrosion resistance, the surface needs to be sprayed with paint of different thicknesses, and it is often difficult to spray to a suitable thickness at one time due to the influence of the physical properties of the paint during spraying. In order to ensure that the thickness of the paint surface reaches a suitable range, it is necessary to spray the steel component multiple times. Equipment that can only perform single spraying is difficult to spray the steel structure quickly and continuously, and customized processing equipment according to the number of spraying times required for the steel structure greatly increases the production cost and reduces the processing efficiency;

[0004] 2. When the spraying device is spraying the steel structure, due to the existence of the supporting surface of the steel structure, the supporting position cannot be sprayed during spraying. The spraying equipment often cannot complete the spraying operation of the steel structure in one go. After one spraying operation, it is often necessary to manually adjust the supporting position and spray again, which is time-consuming and labor-intensive. Utility Model Content

[0005] The utility model aims to provide a spraying device for anti-corrosion treatment of the surface of steel structures in construction. Through a treatment chamber and a spraying chamber, the utility model solves the problem that when anti-corrosion treatment is performed on the surface of steel structures, it is often necessary to control the thickness of the spraying according to the application position of the steel structures. Equipment that can only perform a single spraying operation is difficult to spray the steel structures quickly and continuously. Customizing the treatment equipment according to the number of spraying times required for the steel structures greatly increases the production cost. During spraying, the support positions cannot be sprayed, and after one spraying, the support positions need to be manually adjusted for spraying again.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

When purchasing the spraying device, the staff can purchase an appropriate number of processing bins and spraying bins according to the number of times the steel structure needs to be sprayed, and the bolts penetrate the first connecting plate and the second connecting plate to position and connect the processing bin and the spraying bin. There is no need to customize the spraying device according to the number of spraying times, thereby reducing costs. The spraying bin and the processing bin can be flexibly spliced ​​according to needs, thereby improving the flexibility of the device.

[0009] Furthermore, a limit plate is welded and fixed at the bottom of the processing chamber, a ventilation hole is penetrated through the processing chamber on the other side relative to the blower, a first universal wheel is rotatably connected to the bottom of the processing chamber, and the first conveyor belt is located between the limit slide plate and the limit plate;

[0010] The paint stored at the bottom of the spraying bin can be limited by the limiting plate to prevent the paint from flowing out through the two ends of the processing bin, and the paint after spraying can flow directly into the bottom of the spraying bin under the action of gravity, so that the paint can be recycled and the waste of paint can be avoided.

[0012] The first conveying motor drives the first rotating rod to rotate, which can further drive the movement of the first conveyor belt and the steel structure, so that the steel structure can be dusted or dried by the flow of air driven by the blower while moving, so as to facilitate spraying and discharging of the steel structure.

[0013] Furthermore, a slide groove is provided on the top of the processing chamber, the limiting slide plate is slidably engaged in the slide groove, one end of the bottom of the limiting slide plate is slidably engaged with a lifting cylinder, and the bottom of the lifting cylinder is engaged in the processing chamber;

[0014] The lifting cylinder can drive the limit slide to move up and down along the slide slot, so that when the steel structure has not moved to the side of the limit slide, the limit slide can limit the sprayed paint in the spray chamber, ensuring that the steel structure can perform stable dust removal and drying operations in the processing chamber, avoiding the airflow in the processing chamber from affecting the spraying operation in the spray chamber.

[0015] Furthermore, a feed pipe and a discharge pipe are welded through the bottom of one side of the spraying tank, the feed pipe is located at the top of the discharge pipe, a liquid pump is clamped and fixed at the bottom of one side of the spraying tank, one end of the liquid pump is clamped with a liquid extraction pipe, the top of the liquid pump is clamped with a liquid infusion pipe, the top of the liquid infusion pipe is clamped with a spray pipe, the liquid extraction pipe is inserted through the bottom of one side of the spraying tank, and the spray pipe is inserted through the top of one side of the spraying tank;

[0016] The paint at the bottom of the spray chamber can be pumped into the spray pipe through the liquid pump, and the paint is sprayed onto the surface of the steel structure through the spray pipe, thereby improving the automation level of the spray device.

[0017] Furthermore, a flip motor is clamped at the center of one end of the rotating frame, and the flip motor is clamped through one side of the spraying chamber. A group of second rotating rods are rotatably clamped around the inner side of the rotating frame, and four second conveyor belts are respectively attached to the outer circumferences of the four groups of second rotating rods.

After the steel structure passes through a spraying chamber for a spraying operation, after entering an adjacent spraying chamber, the flipping motor can drive the rotating frame and the steel structure to flip, exposing the contact position between the second conveyor belt and the steel structure, making it easier for the spraying equipment to spray various positions of the steel structure. The structure is simple and the operation is convenient.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that when spraying steel structures, in order to ensure that the steel structures used in different environments have sufficient corrosion resistance, the surface needs to be sprayed with paint of different thicknesses, and it is often difficult to spray to an appropriate thickness at one time due to the influence of the physical properties of the paint during spraying. In order to ensure that the thickness of the paint surface reaches an appropriate range, the steel components need to be sprayed multiple times. Equipment that can only perform single spraying is difficult to spray the steel structure quickly and continuously, and customizing the processing equipment according to the number of spraying times required for the steel structure greatly increases the production cost and reduces the processing efficiency. When purchasing the spraying device, the staff can purchase an appropriate number of processing bins and spraying bins according to the number of spraying times required for the steel structure, and penetrate the first connecting plate and the second connecting plate with bolts to position and connect the processing bin and the spraying bin.

The utility model solves the problem that when a spray device sprays a steel structure, due to the existence of a supporting surface for the steel structure, the supporting position cannot be sprayed during spraying, and the spraying equipment often cannot complete the spraying operation of the steel structure in one go. After one spraying operation, it is often necessary to manually adjust the supporting position and spray again, which is a time-consuming and laborious operation. When the steel structure passes through a spraying bin for one spraying operation, after drying and entering an adjacent spraying bin, the rotating motor drives the rotating frame and the steel structure to flip, exposing the contact position between the second conveyor belt and the steel structure, so that the spraying equipment can spray various positions of the steel structure. The structure is simple and the operation is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
