Description

Technical Field

[0001] This utility model relates to a maintenance device for industrial automatic control, belonging to the technical field of industrial automation equipment. Background Technology

[0002] Industrial automation refers to the technological system and practice model that introduces technologies such as mechanics, electronics, computers, communications, and artificial intelligence into the industrial production process to replace or assist manual labor in completing detection, control, operation, and management processes, thereby achieving high efficiency, precision, unmanned operation, and intelligence in the production process. Its core objectives are to improve production efficiency, ensure product quality, reduce operating costs, reduce safety risks, and promote the transformation and upgrading of traditional manufacturing industries towards "intelligent manufacturing".

[0003] The existing Chinese utility model patent with announcement number CN210452650U describes a maintenance device for industrial automatic control. This patent achieves the purpose of adjusting the height of the maintenance platform by setting up a controller, a rotating motor, a first bevel gear, a second bevel gear, a threaded rod, a horizontal bar, and a vertical bar. The limit block plays a limiting role, and the guide groove and guide column play a guiding role.

[0004] When the above-mentioned maintenance device is used for maintenance, the structure used for maintenance is installed on the upper part of the maintenance platform. However, the sides of the maintenance platform are limited by guide grooves and guide columns, and the bottom is equipped with rollers for movement. This causes the maintenance platform to shake easily during use, which affects the maintenance accuracy of the equipment being maintained and may even damage the equipment being maintained in severe cases. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a maintenance device for industrial automatic control, which forms a rigid connection by setting up multiple sets of mechanisms to jointly eliminate the risk of shaking and avoid the impact of shaking on maintenance accuracy or damage to the equipment being maintained.

[0006] The industrial automatic control maintenance device of this utility model includes a workbench, which is provided with a disassembly area and a maintenance area. The equipment to be disassembled is placed in the disassembly area, and the equipment to be directly maintained is placed in the maintenance area. A controller is fixedly installed on one side of the workbench. The disassembly area and the maintenance area are both equipped with a transverse moving mechanism, a longitudinal moving mechanism, an auxiliary support mechanism, and a connecting mechanism of the same structure. The lateral moving mechanism is fixed on the worktable, and a longitudinal moving mechanism is slidably arranged above the lateral moving mechanism. A support plate is installed above the longitudinal moving mechanism. An auxiliary support mechanism is sleeved on the outside of the support plate to reinforce and support the support plate. The connecting mechanism is installed below the auxiliary support mechanism to connect the support plate to the auxiliary support mechanism.

[0007] The technical solution of this utility model is to provide a maintenance device for industrial automatic control. Equipment to be maintained is categorized according to requirements. Equipment requiring disassembly is placed on a support plate in the disassembly area of ​​the workbench, while equipment requiring direct maintenance is placed on a support plate in the maintenance area. The device is activated by a controller, and according to positional requirements, the lateral movement mechanism drives the longitudinal movement mechanism and the support plate to move laterally. Then, the longitudinal movement mechanism drives the support plate and its longitudinal movement, initially adjusting the equipment to a position convenient for operation. A connecting mechanism connects the support plate to an auxiliary support mechanism, which then reinforces the support plate, reducing its sway. Finally, disassembly operations are performed on the equipment in the disassembly area, and maintenance operations are performed on the equipment in the maintenance area.

[0008] Preferably, the lateral movement mechanism includes a lateral movement module and a limiting frame. Both the lateral movement module and the limiting frame are fixedly connected to the worktable. There are two sets of limiting frames, which are distributed on both sides of the lateral movement module. The limiting frames are arranged parallel to the lateral movement module, and the limiting frames are provided with limiting grooves inside.

[0009] Preferably, the longitudinal moving mechanism includes a longitudinal moving module. The bottom of the longitudinal moving module is fixedly connected to the slide plate on the transverse moving module. Limiting sliders that cooperate with limiting slide grooves are also provided on both sides of the bottom of the longitudinal moving module to guide and limit the longitudinal moving module, ensuring its smooth movement. A support lifting seat and a support plate drive motor are fixed on the slide plate of the longitudinal moving module. The support plate drive motor is located below the top plate of the support lifting seat. The support lifting seat is rotatably connected to a rotating rod and supports the rotating rod. The bottom of the rotating rod is connected to the output shaft of the support plate drive motor through a coupling. The top of the rotating rod is fixedly connected to the support plate. The support plate drive motor can drive the support plate to rotate, thereby adjusting the maintenance angle of the equipment.

[0010] Preferably, the auxiliary support mechanism includes a movable ring, which is mounted on the outside of the support plate by a rotatable connection. Multiple support hydraulic cylinders are evenly fixedly mounted on the movable ring. A support block is fixed to the output end of the support hydraulic cylinder. An annular anti-slip pad is fixed to the lower end of the support block. A groove is provided at the lower end of the support block, and a miniature ranging sensor is fixedly embedded in the groove.

[0011] Furthermore, the height of the movable ring is greater than the height of the support plate, and the lower inner side of the movable ring is provided with an internal tooth array; the lower end of the support plate is fixedly connected to the movable ring drive motor through a mounting bracket, and a drive gear is fixed on the output shaft of the movable ring drive motor. The drive gear meshes with the internal teeth, and the movable ring drive motor can drive the movable ring to rotate.

[0012] Preferably, the connecting mechanism includes a fixed cylinder located below the support plate and movably sleeved on the outside of the rotating rod. Connecting rods are evenly distributed on the outside of the fixed cylinder. The fixed cylinder is fixedly connected to the bottom of the movable ring through the connecting rods, and the connecting rods are offset from the support hydraulic cylinder.

[0013] Furthermore, a clamping block is slidably installed around the bottom of the fixed cylinder. The clamping block has clamping teeth on its inner side and rounded corners on its outer side. A limiting strip is provided at the lower end of the clamping block. A rectangular groove is provided at the bottom of the fixed cylinder corresponding to the position of the limiting strip. The limiting strip is movably locked in the rectangular groove.

[0014] Furthermore, a drive ring is rotatably connected to the inner wall of the fixed cylinder, and a semi-circular protrusion is fixed around the inner wall of the drive ring. The semi-circular protrusion is located in the clockwise direction of the clamping block. An arc-shaped guide groove is opened at the bottom of the fixed cylinder, and an arc-shaped slider is provided at the bottom of the drive ring. The arc-shaped slider is inserted into the arc-shaped guide groove. A locking hydraulic cylinder is hinged to the bottom of the fixed cylinder. A connecting piece is provided on one side of the arc-shaped slider. The connecting piece has an elongated hole. The output end of the locking hydraulic cylinder is movably connected to the arc-shaped slider through the elongated hole. The locking hydraulic cylinder can push the arc-shaped slider to move in the arc-shaped guide groove, causing the drive ring to rotate. Then, through the semi-circular protrusion on the inner wall of the drive ring, it pushes the clamping block to move towards the center of the fixed cylinder, so that the clamping block clamps the rotating rod.

[0015] After adjusting the position and angle of the equipment to be repaired, start the moving ring drive motor of the auxiliary support mechanism. The moving ring drive motor drives the drive gear to rotate, which in turn drives the moving ring to rotate, so that the support hydraulic cylinder on the moving ring is aligned with the stable support point on the worktable. The miniature distance sensor in the support block detects the distance to the worktable and feeds the data back to the controller. The controller controls the support hydraulic cylinder to extend until the annular anti-slip pad at the lower end of the support block is tightly attached to the surface of the worktable. The support block forms an outer auxiliary support for the support plate, reducing swaying. Then, the controller controls the locking hydraulic cylinder of the connecting mechanism to move. The locking hydraulic cylinder pulls the connecting plate, which drives the arc-shaped slider to slide along the arc-shaped guide groove, thereby causing the drive ring to rotate. The semi-circular protrusion on the inner side of the drive ring pushes the clamping block to move towards the center of the fixed cylinder, so that the clamping block clamps the rotating rod. After the rotating rod is clamped, the support plate forms a rigid whole through the rotating rod, fixed cylinder, connecting rod, and movable ring, completely eliminating the risk of shaking of the support plate.

[0016] The advantages of this utility model compared with the prior art are: 1. This utility model achieves basic positioning through a horizontal moving mechanism and a vertical moving mechanism. At the same time, the hydraulic cylinder of the auxiliary support mechanism pushes the support block to fit with the worktable to form multi-point support. The connecting mechanism fixes the rotating rod through the clamping block and forms a rigid connection. The multiple structures work together to eliminate the swaying risk of the support plate and avoid affecting the maintenance accuracy or causing damage to the equipment being maintained due to swaying. 2. This utility model achieves precise horizontal and vertical displacement of the support plate in the plane through the combination of a horizontal moving mechanism and a vertical moving mechanism. The support plate drive motor drives the rotating rod to rotate so as to flexibly adjust the angle of the support plate. The movable ring of the auxiliary support mechanism can adjust the support position through the movable ring drive motor to meet the positioning requirements of different maintenance equipment. Combined with the zoning design of the disassembly area and maintenance area of ​​the workbench, it further improves the convenience of maintenance operation and the applicability of the equipment.
