Description

Technical Field

[0001] The utility model relates to the technical field of manhole cover production, in particular to a manhole cover spraying device with a positioning function. Background Art

[0002] Manhole covers are used to cover deep wells on roads or at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Manhole covers usually need to be sprayed during the processing process, which can improve the corrosion resistance of manhole covers and increase the service life of manhole covers. During the painting process of manhole covers, the spraying position is usually fixed, which leads to uneven spraying and low spraying efficiency.

[0003] After searching, for example, the Chinese patent publication "A high-strength anti-corrosion manhole cover spraying device" with publication number "CN214183757U" can realize automatic rotary spraying on the surface of the manhole cover through the spray box, spray circular plate, rotating shaft, diversion channel, transmission channel, atomizing nozzle, ventilation hole, rotary joint, pump body, spray liquid tank and first motor. The spraying effect is uniform, but the device needs to unload the finished product after the manhole cover is sprayed, and then load it and spray it again, and the spraying efficiency is low. Another example is the Chinese patent publication "A spraying device for preparing high-performance road manhole covers" with publication number "CN2184 86347U", this patent only needs to arrange multiple manhole covers to be painted on the grid conveyor belt at one end of the rectangular support frame, and the second stepper motor is set to drive the grid conveyor belt to rotate, so that the manhole cover is conveyed to the paint spray nozzle, and the paint spray nozzle realizes the painting of the manhole cover. The whole process is convenient to use. Although the spraying effect of this patent is faster, the range of paint sprayed by the nozzle in this patent is wider, which may cause the range of paint spraying to exceed the top area of ​​the manhole cover, resulting in waste of paint. Although a recovery device is also set, impurities in the air in the production room are easy to adhere to the paint, causing impurities in the paint, which may affect the molding effect of the paint layer on the surface of the manhole cover after spraying again.

[0004] Therefore, a manhole cover spraying device with a positioning function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a manhole cover spraying device with a positioning function in order to solve the above-mentioned problem, thereby improving the problem that the spraying device in the comparative patent is difficult to achieve both high spraying efficiency and high spraying accuracy.

After the spraying is completed, the first hydraulic cylinder drives the balance plate and the positioning seat to move upward, and at the same time the lifting assembly is reset to place the manhole cover back to the top of the conveyor roller. Then the manhole cover that has been sprayed is removed, the first hydraulic cylinder will be reset, and the next manhole cover will be blocked by the positioning seat, and then the above operation will be repeated. Compared with the comparative patent, this device not only has high spraying accuracy and will not cause waste of spraying raw materials, but also has higher spraying efficiency and improved production efficiency.

[0007] Preferably, the lifting assembly includes a second hydraulic cylinder arranged on the inner bottom wall of the conveying mechanism, the top of the second hydraulic cylinder is fixedly connected to a load-bearing plate, the top of the load-bearing plate is fixedly connected to an equidistantly distributed lifting plate, the top of the lifting plate is provided with a resistance-increasing pad, the resistance-increasing pad is a wear-resistant rubber material component, when the pressure sensor is subjected to force, the controller will control the second hydraulic cylinder to drive the load-bearing plate and the lifting plate to move upward, at this time the lifting plate will drive the resistance-increasing pad to pass through the gaps between multiple conveying rollers to lift the manhole cover, thereby preventing the bottom of the manhole cover and the surface of the conveying roller from being in a friction state all the time, causing excessive wear of the conveying roller and the manhole cover.

The positioning seat is arc-shaped, and the balls are stainless steel components. When the manhole cover contacts the pressure sensor, it will also contact the balls synchronously to avoid excessive impact of the manhole cover on the pressure sensor and damage to the pressure sensor. When the positioning seat rotates, it drives the balls to rotate on the surface of the manhole cover, and the position of the manhole cover can be adjusted during rotation to avoid the manhole cover from shifting its position after rising, causing misalignment of the spraying range.

[0009] Preferably, the inner walls on both sides of the conveying mechanism are fixedly connected to guide seats, and the inner walls of the guide seats are rotatably connected to equidistantly distributed rotating rods. Before the manhole cover enters the spraying mechanism, its surface will contact the rotating rod and drive the rotating rod to rotate, thereby limiting the position of the manhole cover and aligning it with the positioning seat during movement.

At this time, the manhole cover will be blocked by the positioning seat, and the manhole cover will contact the pressure sensor, which is convenient for positioning the manhole cover to prevent the manhole cover from moving out of the spraying space. At the same time, the lifting component lifts the manhole cover, and the rotating atomizing nozzle driven by the motor sprays the surface of the manhole cover, so as to avoid the spraying range exceeding the manhole cover range, causing the waste of raw materials, and improve the spraying accuracy. After the spraying is completed, the first hydraulic cylinder drives the balance plate and the positioning seat to move upward, and the lifting component resets and places the manhole cover back to the top of the conveying roller. Then the manhole cover that has been sprayed is removed, and the first hydraulic cylinder resets. The next manhole cover will be blocked by the positioning seat again, and then the above operation is repeated. Compared with the comparative patent, this device not only has high spraying accuracy and will not cause waste of spraying raw materials, but also has higher spraying efficiency and improves production efficiency.

[0012] 2. When the pressure sensor is under force, the controller will control the second hydraulic cylinder to drive the load-bearing plate and the lifting plate to move upward. At this time, the lifting plate will drive the resistance-increasing pad to pass through the gaps between multiple conveying rollers to lift the manhole cover, thereby preventing the bottom of the manhole cover and the surface of the conveying roller from being in a state of friction all the time, causing excessive wear of the conveying roller and the manhole cover.
