Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical maintenance, in particular to a clamping mechanism for electromechanical maintenance. Background Art

[0002] In the field of electromechanical maintenance, the main purpose of the clamping mechanism is to improve work efficiency, ensure the safety of operators, and clamp workpieces of different sizes or shapes in a certain position for a long time to facilitate repair and maintenance. The designed structure can be complex and diverse, but the designed operation needs to be simple and easy to use. The mechanical equipment maintained by the electromechanical maintenance lock is mostly finished machinery, electrical appliances and electrical automation equipment that only realize certain functions.

[0003] The existing electromechanical maintenance clamping mechanism has the following problems:

[0004] 1. When repairing electromechanical equipment, in some cases it is suitable to disassemble or observe at a horizontal angle, and in some cases it is suitable to disassemble or observe at a vertical angle. For example, when disassembling a centrifugal pump, first unscrew the pump cover connection nut, and it is easier to use a screw gun when the operator is standing. When disassembling or observing the internal impeller and journal, squatting horizontally with a searchlight to observe the internal situation and then lifting the two sections of the shaft will avoid damaging the impeller. Horizontal clamping on a clamping mechanism and then disassembling and assembling it on another vertical clamping mechanism for secondary maintenance work preparation will delay maintenance time, and the adjustment of the clamping position may also increase the difficulty of construction.

[0005] 2. The existing equipment has a single clamping function and a small clamping size range. Some can only clamp electromechanical equipment of a certain size. In addition, maintenance personnel need to remove the repaired equipment when they adjust the position horizontally after repairing the equipment to install it on another larger equipment. Manually carrying heavy equipment is very laborious and has safety hazards. Using a clamping mechanism for horizontal transportation is much more labor-saving and safer. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , a clamping mechanism for electromechanical maintenance, comprising a base 1 and a slide 6, the inner surface of the slide 6 is rotatably connected with a bidirectional threaded rod 8, the outer surface of the bidirectional threaded rod 8 is threadedly connected with a dovetail block 9, the dovetail block 9 slides on the inner surface of the slide 6, and the dovetail block 9 is set to slide synchronously under the thread transmission on both sides of the bidirectional threaded rod 8, so that two opposite directions of opening or the same direction of approaching can be achieved to achieve the effect of centering clamping, the upper end of the dovetail block 9 is fixedly connected with a 7 clamp, and a V-shaped plate 10 is movably installed on the side of the 7 clamp. The activity mode of the V-shaped plate 10 between the 7 clamps is mainly a rotation angle, and an adjuster 11 is fixedly installed on one side of the 7 clamp. By setting the synchronous approach or opening between the two dovetail blocks 9, the centering clamping of the electromechanical equipment to be repaired is achieved, and the V-shaped plate 10 with a movable connection can rotate the angle to adjust to horizontal clamping or vertical clamping, so that the operator can disassemble the electromechanical equipment such as the centrifugal pump in the order of disassembly in a standing posture or a squatting posture more comfortably;

[0024] The adjuster 11 is internally rotatably connected to the end gear 12, and the inner side of the adjuster 11 is rotatably connected to the second shaft gear 21, the outer surface of the second shaft gear 21 is meshingly connected to the outer surface of the end gear 12, and the side of the second shaft gear 21 is fixedly connected to the turbine 14, and the output end of the turbine 14 is meshingly connected to the worm 15. By setting the worm 15 and the turbine 14, the self-locking function of the V-shaped plate 10 is realized, and the angular position of the V-shaped plate 10 can only be adjusted when the worm 15 is rotated; the inner surface of the adjuster 11 is fixedly connected to the bearing seat 16, and the bearing seat 16 is rotatably connected to the worm 15. The upper end of the worm 15 is fixedly connected to the first rotating wheel 17, and the bearing seat 16 is provided to allow the worm 15 to have a connection outlet and be fixedly connected to the first rotating wheel 17, so that when the first rotating wheel 17 actively rotates to drive the worm 15 to rotate, there is a relatively stable position relationship, thereby avoiding the phenomenon of motion deviation;

[0025] A motor 20 is fixedly installed on the side of the slide 6, and the output end of the motor 20 is fixedly connected to the side of the bidirectional threaded rod 8. The screw rod 4 passes through the inner surface of the base 1 and is fixedly connected to the second rotating wheel 19. By setting a method of manually driving the second rotating wheel 19 and controlling the driving motor 20, the electromechanical equipment can be quickly clamped and then manually operated instead of manually transported, which helps to install and connect the repaired equipment with another equipment.

[0026] See also Figure 1-Figure 4 The base 1 is fixedly provided with a slide rail 2 inside, and a slider 3 is slidably connected to the outer surface of the slide rail 2. The sliding connection between the slide rail 2 and the slider 3 enables the upper end to bear most of the weight of the electromechanical equipment when the slide seat 6 is positioned to clamp the electromechanical equipment. The upper end of the slider 3 is fixedly connected to a fixed block 5. The inner surface of the base 1 is rotatably connected to a screw rod 4. The inner surface of the fixed block 5 is threadedly connected to the outer surface of the screw rod 4. The upper surface of the fixed block 5 is fixedly connected to the lower surface of the slide seat 6. The displacement is transmitted by setting a screw rod 4 threaded connection, so that the weight borne by the fixed block 5 is borne by the slider 3 and the slide rail 2, and the sliding direction and speed are determined by the rotation of the screw rod 4, thereby achieving the effect of carrying the electromechanical equipment in a clamped state to facilitate installation on other equipment.

[0027] A main shaft 18 is fixedly mounted on the side of the end gear 12, and the main shaft 18 is rotatably connected to the inner surface of the adjuster 11. The inner surface of the adjuster 11 is rotatably connected to the first shaft gear 13, and the side of the first shaft gear 13 is meshingly connected to the side of the end gear 12. By arranging the main shaft 18 and the first shaft gear 13 to be rotatably connected at different positions of the adjuster 11, the relative position relationship is determined, and the position of the end gear 12 is supported to ensure that the rotation and meshing movement relationship proceeds normally without a serious tilt position.

[0028] Working principle:

[0029] Step 1: When centering and clamping the electromechanical equipment, the motor 20 drives the bidirectional threaded rod 8 to rotate, so that the V-shaped plates 10 are brought closer together, and the V-shaped groove between the two V-shaped plates 10 is used to clamp the electromechanical equipment such as a centrifugal pump;

[0030] Step 2: After the electromechanical equipment is centered and clamped, the staff needs to be horizontal or tilted to ensure convenient maintenance after disassembly or maintenance is completed in the vertical state. The first rotating wheel 17 is rotated to make the meshing transmission structures such as the worm 15 and the turbine 14 move, and finally the V-shaped plate 10 is tilted relative to the dovetail block 9, so that the clamped electromechanical equipment is clamped in a horizontal state.

[0031] Step three, by rotating the second rotating wheel 19, the slider 3 and the slide rail 2 bear the weight, and the screw rod 4 rotates to drive the fixed block 5 to move horizontally, so as to realize the movement of the clamped electromechanical equipment, so as to replace the operator to carry the equipment, and to facilitate the stable position during the transportation process to facilitate the installation of the repaired equipment on the port of another device.
