Abstract
Description
Technical Field
[0001] The present application relates to the technical field of spraying equipment, and in particular to a guide rail pressure plate spraying device. Background Art
[0002] Rail clamps are usually used on high-speed rail tracks, intercity tracks and subway tracks to tighten the rails. Since the rail clamps need to cooperate with the concrete sleepers on the track, waist-shaped holes for bolts to pass through are opened on the rail clamps. In coastal cities, the relatively humid air can easily corrode the rail clamps, so the rail clamps need to be sprayed with an anti-corrosion layer on their surface before leaving the factory.
[0003] In the related art, the staff will first arrange multiple guide rail pressing plates, and then spray one side of the guide rail pressing plate. When the anti-corrosion paint on the sprayed surface is naturally air-dried, the other side will be sprayed and the other sprayed surface will be allowed to naturally air-dry before the guide rail pressing plate can be placed in the finished product area, thereby reducing work efficiency. Utility Model Content
[0004] In order to improve the work efficiency when spraying the guide rail pressure plate, the present application provides a guide rail pressure plate spraying device.
[0005] The present application provides a guide rail pressure plate spraying device, which adopts the following technical solution:
[0006] A guide rail pressure plate spraying device, comprising:
[0007] The conveying mechanism comprises a conveying belt and a hook assembly installed on the conveying belt to hang the guide rail pressure plate;
[0008] The spraying mechanism includes a paint bucket located below the hook assembly and capable of being sleeved on the guide rail pressing plate after being lifted and lowered, and a paint spray head rotatably installed in the paint bucket for spraying the entire guide rail pressing plate;
[0009] The drying mechanism is located below the conveyor belt and is used for drying the guide rail pressing plate after being sprayed.
[0010] In order to reduce the influence of the hook assembly on the area of the guide rail pressure plate during spraying, the hook assembly includes a fixed hook fixedly installed on the conveyor belt and a thin wire hook detachably installed on the fixed hook.
[0011] In order to drive the paint spray head to rotate so as to achieve multi-angle spraying of the guide rail pressure plate, the spraying mechanism also includes a turntable rotatably installed inside the paint bucket, and the paint spray head is installed on the turntable and rotates synchronously with the turntable.
[0012] A paint pump is installed at the eccentric position of the turntable, and the paint spray head is arranged on the paint pump.
[0013] In order to be able to spray both the upper side wall and the lower side wall of the guide rail pressure plate, three paint spray heads are arranged at intervals along the vertical direction, the top paint spray head is arranged tilted downward, and the bottom paint spray head is arranged tilted upward.
[0014] In order to prevent the paint in the paint bucket from solidifying during the spraying process, the paint pump is provided with a pumping pipe which is inserted into the paint and rotates with the turntable to stir the paint.
[0015] In order to clean out the remaining paint in the paint bucket after the work is finished, a discharge pipe connected to the interior of the paint bucket is provided at the bottom of the paint bucket, and a rubber plug is inserted into the discharge pipe.
[0016] In order to drive the paint bucket to automatically rise and fall, a screw motor group for driving the paint bucket to rise and fall is arranged on the outside of the paint bucket.
[0017] In order to improve the solidification efficiency of the paint on the guide rail pressing plate, the drying mechanism includes a box shell for the guide rail pressing plate to pass through and a heating lamp installed in the box shell to dry the guide rail pressing plate.
[0018] In summary, the present application includes at least one of the following beneficial technical effects:
[0019] The conveying mechanism conveys the guide rail pressing plate to be sprayed to the top of the paint bucket, and the screw motor unit drives the paint bucket to rise, so that the guide rail pressing plate is located in the paint bucket. Then the paint pump rotates with the turntable to spray various positions of the guide rail pressing plate. Finally, the sprayed guide rail pressing plate is conveyed to the box shell and dried at high temperature by the heating lamp, thereby improving the spraying work efficiency.
[0020] The guide rail plate is hung on a thin wire hook. Compared with other thick diameter hooks, the thin wire hook has a smaller projection area on the guide rail plate, which has less impact on spraying. In addition, the thin wire hook can be detached from the fixed hook, so that the thin wire hook can be replaced after long-term use;
[0021] The topmost paint nozzle of the three paint nozzles is tilted downward, and the bottommost paint nozzle is tilted upward, so that both the top and the bottom of the guide rail pressure plate can be sprayed, thereby increasing the spraying range. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0027] The following is combined with Figure 1-4 This application is described in further detail.
[0028] The present application embodiment discloses a guide rail pressure plate spraying device. Figure 1 The guide rail plate spraying device includes a conveying mechanism 1, a spraying mechanism 2 and a drying mechanism 3. The spraying mechanism 2 and the drying mechanism 3 are both located below the conveying mechanism 1, and the drying mechanism 3 is located on one side of the spraying mechanism 2. The conveying mechanism 1 is used to convey the guide rail plate to move. The guide rail plate is first moved to the spraying mechanism 2 station through the conveying mechanism 1 to realize spraying; then the guide rail plate is moved to the drying mechanism 3 position for drying, so as to improve the working efficiency during spraying.
[0029] Reference Figure 1 The conveying mechanism 1 includes a conveying frame 11, a conveying belt 12 and a hook assembly 13. The conveying belt 12 is installed on the conveying frame 11, and a conveying motor capable of driving the conveying belt 12 is provided on the conveying frame 11. The hook assembly 13 is provided on the conveying belt 12 and moves synchronously with the conveying belt 12, and the guide rail pressure plate is hung on the hook assembly 13. Among them, the hook assembly 13 is provided with multiple groups, and the multiple groups of hook assemblies 13 are arranged at intervals on the conveying direction of the conveying belt 12. The following is described by taking one group of hook assemblies 13 as an example.
[0030] Reference Figure 1 and Figure 2The hook assembly 13 includes a fixed hook 131 and a thin wire hook 132. The diameter of the thin wire hook 132 is smaller than that of the fixed hook 131, but the thin wire hook 132 can hook up the guide rail scraper without deformation. The fixed hook 131 is fixedly installed on the conveyor belt 12, and a hanging ring is bent at the top of the thin wire hook 132. The thin wire hook 132 is hung on the fixed iron hook through the hanging ring. When the thin wire hook 132 needs to be replaced, it only needs to be removed. The thin wire hook 132 hooks up the guide rail pressure plate through the waist-shaped hole on the guide rail pressure plate.
[0031] Reference Figure 2 and Figure 3 The spraying mechanism 2 includes a screw motor group 21 (composed of a motor and a screw), a paint bucket 22, a turntable 23, a paint nozzle 24 and a paint pump 25. The screw motor group 21 drives the paint bucket 22 to rise and fall so that one of the guide rail pressing plates on the conveyor belt 12 is sleeved inside the paint bucket 22. The paint bucket 22 contains the paint to be sprayed, the turntable 23 is located above the paint liquid level and the turntable 23 is rotatably installed in the paint bucket 22. The paint nozzle 24 is installed on the paint pump 25, the paint pump 25 is located at the eccentric position of the turntable 23, and the paint pump 25 rotates synchronously with the turntable 23, thereby realizing multi-directional spraying of the guide rail pressing plate.
[0032] Reference Figure 2 and Figure 3 , there are two groups of screw motor groups 21, and the two groups of screw motor groups 21 are arranged at intervals on the outside of the paint bucket 22. Two lug blocks 221 are integrally formed on the outer wall of the paint bucket 22, and the two lug blocks 221 correspond to the two groups of screw motor groups 21 one by one. The screw in the screw motor group 21 passes through the lug block 221 and is threadedly connected with the lug block 221, and the motor in the screw motor is fixed on the platform. When the guide rail pressure plate needs to be sprayed, the screw motor group 21 drives the paint bucket 22 to rise. After spraying one of the guide rail pressure plates, the screw motor group 21 drives the paint bucket 22 to descend to make way for the movement of the guide rail pressure plate.
[0033] A discharge pipe 222 is integrally formed at the bottom of the exterior of the paint bucket 22. The discharge pipe 222 is connected to the interior of the paint bucket 22. A rubber plug 223 is inserted into the discharge pipe 222 to plug the discharge pipe 222. When a day's work is finished, the worker can pull the rubber plug 223 out of the discharge pipe 222, and the remaining paint in the paint bucket 22 will be discharged through the discharge pipe 222.
[0034] Reference Figure 2 and Figure 3A motor bracket 26 is fixedly installed at the bottom of the paint bucket 22, and a rotating motor 27 is fixedly installed on the top of the motor bracket 26. The turntable 23 rotates by rotating the motor 27. In this embodiment, three paint spray heads 24 are preferably arranged, and the three paint spray heads 24 are arranged at intervals along the vertical direction on the paint pump 25. The top paint spray head 24 is tilted downward; the bottom paint spray head 24 is tilted upward; the middle paint spray heads 24 are arranged radially along the turntable 23. In this way, multi-angle spraying of the guide rail plate can be achieved.
[0035] A draw pipe 251 is fixedly installed at the bottom of the paint pump 25. The draw pipe 251 is a hard plastic pipe. The draw pipe 251 penetrates the turntable 23 and is inserted below the paint liquid surface. The paint pump 25 draws the paint in the paint bucket 22 through the draw pipe 251 and sprays it through the paint nozzle 24. In addition, as the turntable 23 rotates, the draw pipe 251 also rotates, thereby stirring the paint in the paint bucket 22, so that the paint is not easy to solidify.
[0036] Reference Figure 3 The drying mechanism 3 includes a box shell 31 and a heating lamp 32 disposed on the inner wall of the box shell 31. The top of the box shell 31 and both sides of the box shell 31 along the conveying direction of the guide rail pressing plate are open, so that the guide rail pressing plate after spraying can pass through the inside of the box shell 31. When the guide rail pressing plate after spraying passes through the inside of the box shell 31, the high temperature generated by the heating lamp 32 will dry the guide rail pressing plate.
[0037] The implementation principle of a guide rail plate spraying device in an embodiment of the present application is as follows: first, the guide rail plate to be sprayed is hung on a thin iron wire hook 132 , and the conveyor belt 12 will drive the guide rail plate to move and move it to just above the paint bucket 22 .
[0038] Afterwards, the screw motor group 21 will drive the paint bucket 22 to rise, so that the guide rail pressure plate is located inside the paint bucket 22. At the same time, the rotating motor 27 drives the turntable 23 to drive the paint pump 25 to move and make the paint nozzle 24 spray the paint toward the guide rail pressure plate. During this process, the conveyor belt 12 stops moving.
[0039] After spraying is completed, the screw motor group 21 drives the paint bucket 22 to descend to make way for the movement of the guide rail pressing plate, and the conveyor belt 12 will restart to drive the guide rail pressing plate to move toward the drying mechanism 3. When the sprayed guide rail pressing plate passes through the inside of the box shell 31, the high temperature generated by the heating lamp tube 32 will dry the paint on the guide rail pressing plate.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
