Description

Technical Field

[0001] This utility model relates to the field of surface processing technology for pipe-seam anchor bolts, and in particular to a surface coating device for pipe-seam anchor bolts. Background Technology

[0002] Pipe joint anchors are commonly used support components in mining roadways and tunnels. Their working principle is to achieve anchoring through the friction between the rod and the rock wall. Due to long-term exposure to humid, high-stress, or corrosive environments (such as mine water and rock fissure water), the rod is prone to rust and wear, leading to a decrease in anchoring force or even failure, which threatens the safety of the project. Therefore, during the production process, it is necessary to spray anti-corrosion coating on its surface to improve the service life of the equipment.

[0003] Existing coating devices require manual loading and unloading of materials during installation and use. During the unloading process, the coating on the surface of the anchor bolt after spraying is easily damaged by the workers, affecting the spraying effect and causing certain adverse effects on the use process. In order to overcome the shortcomings of the existing technology, we propose a coating device for the surface of pipe seam anchor bolts. Utility Model Content

[0004] The main objective of this invention is to provide a surface coating device for pipe seam anchor bolts, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A surface coating device for pipe joint anchor bolts includes a workbench. Two sets of support rods of different heights are horizontally welded to the inner side of the workbench. A pouring rod is symmetrically arranged above the two sets of support rods. A fixing ring is welded to the upper end of each pouring rod, and the fixing ring is sleeved on the outside of one set of support rods. Multiple grooves corresponding to the pouring rods are provided on the inner wall of the other set of support rods. A baffle is provided on the inner side of the workbench, and a collection trough is provided below the baffle. A receiving rack is provided at the rear end of the workbench. Multiple receiving rods are welded to the upper interior of the receiving rack, and multiple stop rods are welded to the upper right side of the receiving rack.

[0007] Preferably, a first motor is arranged on the upper left side of the workbench, a first cylinder is arranged on the upper right side, and two sets of sliding rods are horizontally and symmetrically welded on the upper inner side of the workbench. A sliding base is arranged inside the upper part of the workbench, and both sets of sliding rods pass through the lower inner wall of the sliding base. A mounting groove is arranged in the middle inner wall of the sliding base. A conical clamping block is arranged on the rotor end of the first motor and one side of the sliding base, and a rotating bearing is sleeved on the outer side of one set of conical clamping blocks. A pressure plate is arranged inside the upper part of the sliding base. A fixing groove is horizontally welded to the rear end of the workbench, and a transmission rod is rotatably connected inside the fixing groove. A second motor is arranged at the right end of the fixing groove, and the rotor end of the second motor is connected to one end of the transmission rod. A mounting bracket is arranged above the fixing groove, and the transmission rod passes through the lower inner wall of the mounting bracket. A second cylinder is arranged on the upper surface of the front end of the mounting bracket.

[0008] Preferably, the inner diameter of the fixing ring is larger than the outer diameter of the support rod at the top, and a groove is provided on the inner wall of the outer side of the support rod to fit the outer surface of the pouring rod.

[0009] Preferably, the baffle is welded to the inner side of the workbench in an inclined state, and the baffle is located below the two sets of pouring rods. The collecting trough is located below the baffle, and the receiving rod is welded to the inner side of the receiving frame in an inclined state.

[0010] Preferably, the first cylinder and the first motor are detachably mounted on the left and right sides of the worktable, and a set of conical clamping blocks are detachably mounted on the rotor end of the first motor, while another set is movably mounted on one side of the sliding base through a rotating bearing and a mounting groove.

[0011] Preferably, the telescopic end of the first cylinder is detachably connected to the other side of the sliding base, and the sliding base is slidably connected above the two sets of sliding rods. The mounting bracket is threadedly connected to the transmission rod, and a nozzle is detachably installed at the lower end of the second cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, a first cylinder pushes a sliding base to slide inside the worktable above it. Under the action of two sets of conical clamps, the two ends of the anchor rod are clamped. Then, a first motor controls the anchor rod to rotate, and a nozzle below the second cylinder sprays paint onto the surface of the anchor rod, thereby improving its service life.

[0014] In this invention, when the sliding base is reset by the first cylinder, the painted anchor rods automatically fall below the two sets of pouring rods. Since the pouring rods are tilted, the anchor rods roll along the pouring rods under the action of gravity to the top of the receiving frame for collection. During the rolling process, excess paint adhering to the surface of the anchor rods automatically drips onto the top of the baffle and is collected by the collection trough.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Example 1, as Figures 1-3 As shown, a surface coating device for pipe seam anchor bolts is described. Before use, the device is first connected to the existing power supply and air compressor equipment. Then, the operator manually places the anchor bolt to be coated horizontally above the workbench 1, with one end pressed against the conical clamping block 8 at the rotor end of the first motor 4. The first cylinder 3 is then activated, pushing the sliding base 5 to move slowly inside the workbench 1, controlling another set of conical clamping blocks 8 to press against the other end of the anchor bolt, thus clamping it. The first motor 4 is then activated, controlling the conical clamping block 8 to rotate, causing the anchor bolt to rotate. Then, a hose is used to connect the nozzle below the second cylinder 14 to the existing spraying equipment. The spraying equipment atomizes the paint into tiny particles and uses air pressure to spray them out from the nozzle, allowing the paint to adhere to the surface of the anchor bolt and form a protective coating. After spraying is completed, the first cylinder 3 retracts, controlling the sliding base 5 to return to its original position. At this time, the coated anchor bolt falls from between the two sets of conical clamping blocks 8 onto the top of the pouring rod 18.

[0021] Example 2, as Figures 1-3As shown, a surface coating device for pipe seam anchor bolts uses multiple sets of grooves on the outer wall of the support rod 15 in conjunction with the fixing ring 19. This allows workers to easily adjust the distance between the two sets of pouring rods 18 according to the length of the anchor bolt, ensuring that the anchor bolt falls evenly above the pouring rods 18. Since the pouring rods 18 are inclined, when the anchor bolt falls below the pouring rods 18, it automatically rolls down to the top of the receiving frame 20 under the action of gravity. The multiple sets of receiving rods 22 support the coated anchor bolts, and the multiple sets of stop rods 21 support the sides of the anchor bolts. Once a suitable amount of anchor bolts have been collected above the receiving frame 20, workers need to replace them promptly.

[0022] It should be noted that this utility model is a surface coating device for pipe seam anchor rods. In use, after the worker clamps the anchor rod, the second motor 11 is started. The second motor 11 controls the rotation of the transmission rod 12. Since the mounting bracket 13 is threadedly connected to the transmission rod 12, the mounting bracket 13 can be controlled to move above the fixed groove 10 during rotation. At the same time, the baffle welded to the back and top of the worktable 1 prevents the paint from contacting the transmission rod 12. The height of the nozzle can be controlled by the second cylinder 14 to improve the spraying effect. Since the pouring rod 18 is in an inclined state, when the sprayed anchor rod falls, it will hit the pouring rod 18. The excess paint adhering to its surface will drip onto the baffle 16. At the same time, since the baffle 16 is also in an inclined state, it can effectively block the paint during the spraying process and prevent the mist-like paint from spreading out from the gap between the collection tank 17 and the worktable 1.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
