Description

Technical Field

[0001] This utility model relates to the field of painting technology for hydraulic gate opening and closing machinery, and in particular to a painting device for hydraulic gate opening and closing machinery. Background Technology

[0002] In water conservancy projects, hydraulic gate opening and closing machinery, as the core structure for controlling the raising and lowering of gates, is exposed to humid, salt spray, or chemically corrosive environments for extended periods. The quality of its surface anti-corrosion coating directly affects the service life of the equipment.

[0003] Existing hydraulic gate hoist painting devices often employ a design disclosed in CN211801967U, where the gate hoist on a motor-driven workbench rotates, the spray gun operates, and a moving plate is pushed. The moving plate, through the cooperation of a slider and a groove, changes the distance between the spray gun and the gate hoist, thus altering the area painted by the spray gun. However, the device used for rotating the gate hoist and adjusting the distance between the hoist and the spray gun does not mention any actual fixing device. This lack of effective limiting measures for hydraulic gate hoists makes them prone to displacement or even tilting during dynamic painting. Furthermore, the use of a general-purpose clamping structure easily leads to blind spots on the outer surface of the hydraulic gate hoist. Moreover, the existing hydraulic gate hoist structure is large and multifaceted, making it difficult for painting equipment that only allows for linear distance adjustment to guarantee comprehensive painting. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of instability and uneven spraying during operation of the existing gate hoist spraying device, and to propose a painting device for hydraulic gate hoisting machinery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A painting device for hydraulic gate opening and closing machinery includes a circular base and an integrated platform concentrically arranged on a base plate. A spray gun is movably mounted on the circular base. The integrated platform is composed of a square support platform and a rectangular platform. The integrated platform vertically holds the hydraulic gate opening and closing machinery equipped with a limiting flange through the rectangular platform. The integrated platform is also equipped with a limiting mechanism for fixing the hydraulic gate opening and closing machinery through the square support platform. A rotary drive mechanism for driving the spray gun to revolve around the hydraulic gate opening and closing machinery to achieve painting processing is installed in the circular base.

[0007] Preferably, the rectangular platform and the square support platform are integrally connected from top to bottom.

[0008] Preferably, the rectangular platform has a countersunk hole with a diameter smaller than the outer diameter of the hydraulic opening and closing mechanism's limiting flange.

[0009] Preferably, the limiting mechanism includes sliding grooves on the left and right sides of the square support platform, with a slider slidably disposed in each of the two sliding grooves. A sliding sleeve is welded to the center of the square support platform, and a hydraulic cylinder is fixedly disposed inside the sliding sleeve. A mounting plate is fixedly connected to the output end of the hydraulic cylinder, which is fitted inside the sliding sleeve and used to move and pull the slider. A pin is connected to the sliding sleeve to a clamping rod that is moved and pulled by the slider and used to support and fix the hydraulic opening and closing mechanism.

[0010] Preferably, a first connecting rod is pinned between the slider and the mounting plate, and a second connecting rod is pinned between the slider and the locking rod.

[0011] Preferably, the rotary drive mechanism includes a square hole in the outer wall of the annular base, a drive motor is fixedly installed in the square hole, a drive gear is keyed to the drive motor, an annular groove communicating with the square hole is opened in the middle of the annular base, and an external gear ring that meshes with the drive gear is movably installed in the annular groove. An annular slide rail that is slidably fitted in the annular groove and used to fix the spray gun is integrally connected below the external gear ring.

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

[0013] 1. This utility model has a countersunk hole for placing the hydraulic opening and closing mechanism on a rectangular platform, and a limiting mechanism is set between the square support platform and the countersunk hole.

[0014] 2. This utility model has a rotary drive structure installed in the circular base. The drive gear drives the external gear ring to rotate under the limit of the annular slide rail, so that the spray gun can rotate concentrically with the integrated base along the rotation direction of the annular slide rail.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A painting device for hydraulic gate opening and closing machinery includes a circular base 2 and an integrated base 3 concentrically arranged on a base plate 1. The integrated base 3 is inside the circular base 2. A spray gun 5 is movably arranged on the circular base 2. The integrated base 3 is composed of a square support platform 31 and a rectangular platform 32. The rectangular platform 32 and the square support platform 31 are integrally connected from top to bottom. The square support platform 31 and the rectangular platform 32 are integrally connected by four circumferentially equidistant support columns. A countersunk hole 4 with a diameter smaller than the outer diameter of the limiting flange of the hydraulic gate opening and closing machinery is opened in the rectangular platform 3. The integrated base 3 is used to vertically place the hydraulic gate opening and closing machinery equipped with the limiting flange through the rectangular platform 32.

[0023] The integrated base 3 is equipped with a limiting mechanism 7 for fixing the hydraulic opening and closing mechanism via a square support platform 31. The limiting mechanism 7 abuts against and fixes the hydraulic opening and closing mechanism from the inside. The circular base 2 is equipped with a rotary drive mechanism 6 for driving the spray gun 5 to revolve around the hydraulic opening and closing mechanism to achieve the painting process. It should be noted that the spray gun 5 includes a hose, a paint tank, and an electric telescopic rod nozzle. The paint tank provides paint to the nozzle through the hose. At the same time, the spray gun 5, which revolves, moves vertically up and down, so that the nozzle of the spray gun 5 is fixed at the lowest point of the electric telescopic rod and sprays paint once before slowly rising vertically. This ensures that the paint on the surface of the hydraulic opening and closing mechanism is sprayed evenly and completely, and at the same time makes the device more adaptable.

[0024] The limiting mechanism 7 includes sliding grooves 71 located on the left and right sides of a square support platform 31. A slider 72 is slidably mounted in each of the two sliding grooves 71. A sliding sleeve 73 is welded to the center of the square support platform 31. A hydraulic cylinder 74 is fixedly mounted inside the sliding sleeve 73. A mounting plate 75, which is slidably fitted inside the sliding sleeve 73 and used to move and pull the slider 72, is fixedly connected to the output end of the hydraulic cylinder 74. A pin is pin-connected to the sliding sleeve 73 to a lever 78, which is moved and pulled by the slider 72 and used to support and fix the hydraulic gate opening and closing mechanism. A support platform is welded to the upper end of the sliding sleeve 73 for pin-connecting the lever 78. The slider 72... A first connecting rod 76 is pin-connected to the mounting plate 75. A through hole is provided in the middle of the sliding sleeve 73 for the first connecting rod 76, which is pin-connected to the slider 72, to rotate up and down. A second connecting rod 77 is pin-connected between the slider 72 and the locking rod 78. The locking rod 78 is pulled by the horizontal thrust of the slider 72 and the first connecting rod 76, which drives the second connecting rod 77 to generate a downward traction force on the locking rod 78, thereby causing the locking rod 78 to open. The sliding groove 71, slider 72, first connecting rod 76, second connecting rod 77 and locking rod 78 can be increased to four if conditions permit, which helps to apply pressure and limit the hydraulic opening and closing machinery in more directions.

[0025] The rotary drive mechanism 6 includes a square hole 61 formed in the outer wall of the annular base 2. The square hole 61 is located outside the annular base 2, and a drive motor 62 is fixedly mounted thereon. A drive gear 63 is keyed to the drive motor 62. An annular groove 64 communicating with the square hole 61 is formed in the middle of the annular base 2. An external gear ring 65, meshing with the drive gear 63, is movably mounted within the annular groove 64. When the drive motor 62 rotates, it drives the drive gear 63, thereby rotating the external gear ring 65 meshing with the drive gear 63. (See the attached instruction manual for details.) Figure 2 Through the meshing transmission between the drive gear 63 and the external gear ring 65, the annular slide rail 66 drives the spray gun 5 to revolve around the hydraulic opening and closing mechanism during slow rotation, ensuring uniform spraying speed and avoiding incomplete spraying caused by excessive rotation speed. The annular slide rail 66, which is integrally connected to the lower part of the external gear ring 65 and is slidably fitted in the annular groove 64, is used to fix and install the spray gun 5. Under the action of the annular slide rail 66, the spray gun 5 rotates concentrically and sprays paint evenly on the surface of the hydraulic opening and closing mechanism.

[0026] It should be noted that the specific model and specifications of the drive motor 62 and spray gun 5 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0027] The functional principle of this utility model can be explained through the following operation methods:

[0028] The hydraulic opening and closing mechanism is placed vertically through the countersunk hole 4 in the rectangular platform 32 until the limiting flange abuts against the rectangular platform 32;

[0029] The hydraulic cylinder 74 is opened, causing the mounting plate 75 to move vertically downward along the sliding sleeve 73. The first connecting rod 76 pushes the slider 72 to move along the sliding groove 71. The slider 72 pulls the locking rod 78 to open and deflect through the second connecting rod 77 until the locking rod 78 abuts against the inner wall of the hydraulic opening and closing mechanism.

[0030] The drive motor 62 is turned on on the circular base 2. The drive gear 63 and the external gear ring 65 drive the annular slide rail 66 to rotate in the annular groove 64, so that the spray gun 5 revolves around the hydraulic opening and closing mechanism to spray paint the outer wall of the hydraulic opening and closing mechanism.
