Description

Technical Field

[0001] The utility model relates to a spraying device, in particular to a reciprocating machine for spraying bridge frames. Background Art

[0002] After the bridge frame is processed, in order to extend its service life, a protective coating is sprayed on the outside of the bridge frame to isolate the surface of the bridge frame from the external environment and prevent the erosion of chemical substances such as acids, alkalis, and salts on the surface of the object. Due to the simple structure of the bridge frame product, during the spraying process, according to the operating space, operating convenience, and the shape and size of the product, the spraying requirements of the bridge frame product can be met by adopting two methods: vertical spraying or horizontal spraying.

[0003] Spraying operation will use a reciprocating spraying machine. With the development of technology, there have also appeared automatic reciprocating machines on the existing market that can achieve multi-dimensional movement. However, such reciprocating machines are often extremely expensive, and the higher the degree of automation, the higher the failure rate and the later maintenance cost. For the spraying operation of simple products, such as bridge frames, if this highly automated reciprocating machine is used, it will cause a great waste of costs. Moreover, the extremely high investment in equipment costs is not suitable for some small and micro enterprises, and this operation will also increase the selling cost of the product, thereby reducing the market competitiveness of the product. Based on the above problems, the present invention was born. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reciprocating machine for spraying bridge frames. The reciprocating machine for spraying bridge frames has a simple structure and can achieve vertical spraying or horizontal spraying, so as to reduce the equipment investment cost, the later selling cost and maintenance cost of the enterprise, and improve the market competitiveness of the product.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A reciprocating machine for spraying bridge frames includes a base, a horizontal sliding arm, a second sliding seat that reciprocates linearly and slides on the horizontal sliding arm, a driving component arranged on the horizontal sliding arm and used to drive the movement of the second sliding seat, a gun rack, and a plurality of spray guns installed on the gun rack. The gun rack is rotatably connected to the second sliding seat, and a locking structure is arranged between the two. A vertical sliding arm is arranged on the base, and a first sliding seat reciprocates vertically and slides on the vertical sliding arm. The horizontal sliding arm is longitudinally rotatably arranged on the first sliding seat. A locking component is formed between the horizontal sliding arm and the vertical sliding arm, and the locking component locks the horizontal sliding arm in a horizontal or vertical state.

[0006] By adopting the above technical solution, the horizontal sliding arm is rotatably arranged on the first sliding seat, and the first sliding seat is cooperatively arranged to enable the height adjustment of the horizontal sliding arm while realizing the switching of the horizontal sliding arm between the horizontal and vertical states.

[0012] By adopting the above technical solution, the limit seat drives the locking claw to rotate towards the locking bar side to engage the locking bar into the claw opening, and then rotates the control bolt to drive the control block to move. The moving control block drives the two claw teeth to move towards each other under the action of the linkage structure, and then bites the locking bar to form a fixation.

[0013] Further set as: The linkage structure includes a linkage groove formed in the control block, a linkage inclined surface formed in each claw tooth and cooperating with the linkage groove, and a return spring for driving the two claw teeth to move away from each other. The linkage groove cooperates with the linkage inclined surface to drive the two claw teeth to move towards each other.

[0014] By adopting the above technical solution, the cooperation between the linkage groove and the linkage inclined surface is used to change the direction of the acting force, and the reciprocating movement between the two claw teeth can be realized with the cooperation of the set return spring.

[0015] Further set as: A guide ring is provided at the top of the vertical sliding arm, and a control rope passing through the guide ring is connected to the first sliding seat.

[0016] By adopting the above technical solution, the control rope pulls the first sliding seat to adjust the height of the horizontal sliding arm, making the height adjustment operation of the horizontal sliding arm more convenient.

[0017] In summary, the present utility model has the following beneficial effects: The structure of the present utility model is simple and can achieve vertical spraying or horizontal spraying, thereby reducing the equipment investment cost of the enterprise and the selling cost and maintenance cost of the later products, and enhancing the market competitiveness of the products.
