Description

Technical Field

[0001] The invention relates to the technical field of power equipment maintenance, in particular to an indoor 35kV switch operation anti-dumping device. Background Art

[0002] In the 35kV distribution room of the substation, the 35kV indoor trolley switch is tall, large and heavy. There are two ways to pull the trolley switch from the experimental position to the maintenance position: 1. Temporarily install an outward-tilted operating gasket on the door of the switch cabinet. When pulling the trolley switch out of the switch cabinet, directly pull the switch out to the ground through the outward-tilted operating gasket. Improper operation force or displacement of the operating gasket will cause the switch to topple over and become inoperable or injure the operator. When the switch is moved from the cabinet to the ground, there is a 4-6cm height difference with the ground. Although there is a slope pad for transition, it is still difficult to ensure reliability during operation. 2. Use a guide rail to pull the switch out. One side of the guide rail is fixed on the switch cabinet, and the other side is cut outward to the ground. Because the guide rail is placed on the ground without any other protection, the switch immediately tilts downward and slides when pulled out. Under the influence of gravity, it will accidentally topple over and injure the operator or damage the switch. Summary of the invention

When the trolley switch is pulled from the experimental position of the switch cabinet to the maintenance position, and the switch trolley is bent over to pull and push, the switch trolley is prone to tilt and overturn, causing injuries or damage to the switch.

[0028] Specifically, the support unit 100 includes a support assembly 101 and an anti-dumping assembly 102 disposed on one side of the support assembly 101;

[0029] The pushing unit 200 includes a pushing assembly 201 disposed on one side of the supporting assembly 101 , and a locking assembly 202 disposed on one side of the pushing assembly 201 .

[0030] Further, the support assembly 101 includes a switch trolley bracket 101a, a guide member 101b disposed at the bottom of the switch trolley bracket 101a, an adjustment bolt 101c disposed on the upper side of the bottom support plate 101b-1, and two sets of handles 101d disposed on the outside of the switch trolley bracket 101a;

[0031] The guide member 101b includes a bottom support plate 101b-1 arranged at the bottom of the switch trolley bracket 101a, two sets of guide rails 101b-2 arranged on the upper side of the bottom support plate 101b-1, a sliding block 101b-3 fixedly connected to the bottom of the guide rails 101b-2, and four sets of through grooves 101b-4 symmetrically opened on the bottom support plate 101b-1.

[0032] It should be noted that four sets of universal wheels are installed at the bottom of the switch trolley bracket 101a. The universal wheels are locked to ensure that the trolley does not move when the switch cabinet is pulled out, making it more convenient to turn when transporting the switch cabinet.

[0033] Furthermore, the direction of the guide rail 101b-2 is parallel to the movement direction of the switch, the bottom of the guide rail 101b-2 is fixedly connected to the sliding block 101b-3, the bottom support plate 101b-1 is symmetrically provided with four groups of through grooves 101b-4, the sliding block 101b-3 is slidably set on the inner side of the through grooves 101b-4, and the spacing of the guide rail 101b-2 is adjusted to be the same as the spacing of the rollers set by the switch through the through grooves 101b-4 and the sliding block 101b-3, and the width of the guide rail 101b-2 is slightly larger than the width of the roller.

[0034] It should be noted that the dimension of the through slot 101b-4 in the direction perpendicular to the guide rail 101b-2 is larger than that of the sliding block 101b-3, and the dimension range of the through slots 101b-4 at both ends is adapted to the commonly used spacing of the switch cabinet rollers, and the dimension of the through slot 101b-4 parallel to the guide rail 101b-2 is adapted to the dimension of the sliding block 101b-3, thereby limiting the sliding block 101b-3.

[0035] Furthermore, the adjusting bolts 101c are respectively arranged on the inner sides of the two sets of guide rails 101b-2, and cooperate with the slider and the through slot 101b-4 to drive the guide rails 101b-2 to adjust the spacing.

[0036] It should be noted that the adjusting bolt 101c includes a bolt and a base. The end of the bolt close to the guide rail 101b-2 is the control end, and the end away from the guide rail 101b-2 is the adjustment end. The adjustment end is provided with a knob. The base is fixedly connected to the bottom support plate 101b-1, and the control end of the bolt is fixedly connected to the guide rail 101b-2. The staff adjusts the spacing of the guide rail 101b-2 by turning the knob at the adjustment end.

[0037] Furthermore, the anti-dumping assembly 102 includes a foldable armrest 102a disposed on one side of the switch trolley bracket 101a, wherein the foldable armrest 102a includes a fixed section and a folding section, the fixed end is fixedly connected to the switch trolley bracket 101a, and the folding section is hinged to the fixed end.

[0038] Furthermore, the pushing assembly 201 includes a hydraulic rod 201a arranged on the inner side of the supporting assembly 101, an electric operating arm 201b arranged at one end of the hydraulic rod 201a, and a pushing rod 201c arranged at one end of the electric operating arm 201b, wherein the hydraulic rod 201a includes a hydraulic cylinder and a telescopic rod, the hydraulic cylinder is fixedly connected to the switch trolley bracket 101a, the telescopic rod is fixedly connected to the electric operating arm 201b, and the pushing rod 201c is hinged to the electric operating arm 201b.

[0039] Furthermore, the locking assembly 202 includes a lock catch 202a penetrating the inner side of the pushing rod 201c, and a driving spring 202b disposed at both ends of the lock catch 202a.

[0040] Furthermore, the lock buckle 202a is provided with an inwardly facing hook on the side close to the 35kV switch. There are two groups of lock buckles 202a, which are symmetrically arranged at both ends of one side of the push rod 201c, and the spacing between them is adapted to the corresponding groove of the switch.

[0041] Furthermore, one end of the driving spring 202b is fixedly connected to the inner wall of the pushing rod 201c and the other end is fixedly connected to the base of the lock buckle 202a. When the driving spring 202b is in the initial position, the lock buckle 202a is in a parallel state.

[0042] Furthermore, a cabinet connection latch is provided on the outer side of the bottom support plate 101b-1 for locking the switch trolley for easy pushing and pulling.

[0043] During use, when maintenance is required, the staff adjusts the adjustment bolt 101c according to the roller of the switch cabinet to make the spacing of the guide rail 101b-2 the same as the spacing of the rollers. Further, the staff pushes the switch trolley bracket 101a to the front of the switch cabinet through the handle 101d, so that the cabinet connection card is inserted into the lower side of the cabinet. Further, the staff controls the hydraulic rod 201a to extend outward, and the hydraulic rod 201a pushes the electric operating arm 201b to extend outward until the pushing rod 201c contacts the switch cabinet. At this time, the hook provided by the lock buckle 202a is squeezed by the groove provided by the switch cabinet and rotates outward, driving the base of the lock buckle 202a to rotate inward, and the base of the lock buckle 202a drives the driving spring 202b to stretch. When the hook of the lock buckle 202a passes the outer edge of the groove, the tensile force of the driving spring 202b contacts, and the driving spring 202b returns to the initial state, driving the base of the lock buckle 202a to rotate outward. The lock catch 202a is driven to rotate to the initial position, so that the hook of the lock catch 202a is stuck in the inner side of the groove, so that the pushing rod 201c is fixedly connected to the switch cabinet. Further, the staff controls the hydraulic rod 201a to retract inward, and the hydraulic rod 201a drives the electric operating arm 201b to retract inward. The electric operating arm 201b pulls the pushing rod 201c to move synchronously in the same direction. The pushing rod 201c drives the switch cabinet to move synchronously in the same direction through the lock catch 202a. When the switch cabinet moves to the point where the roller completely enters the guide rail 101b-2, the hydraulic rod 201a is retracted to the initial position, and the electric operating arm 201b drives the pushing rod 201c to retract to the initial position. At the same time, the staff folds the handrails and puts them down to protect the two sides of the switch cabinet from tipping over. Further, the staff pulls the switch trolley bracket 101a through the handle 101d to drive the switch cabinet to continue to move outward to the maintenance position to perform switch cabinet maintenance.

[0044] When the inspection is completed, the staff pushes the switch trolley bracket 101a through the handle 101d to drive the switch cabinet to move to the front of the experimental position. Further, the staff lifts the folding handrail. Further, the staff controls the hydraulic rod 201a to extend outward. The hydraulic rod 201a pushes the electric operating arm 201b to extend outward. The electric operating arm 201b pushes the switch cabinet to move outward through the pushing rod 201c. The rollers provided on the switch cabinet assist the switch cabinet to move outward to the experimental position along the guide rail 101b-2. Further, the staff pushes the base of the lock buckle 202a inward to put the driving spring 202b in a stretched state. At this time, the hook provided on the lock buckle 202a rotates outward following the movement of the base of the lock buckle 202a, and the lock buckle 202 a The hook releases the lock on the groove provided in the switch cabinet. After the staff moves the hook out of the groove, the base of the lock buckle 202a is loosened. At this time, the tensile force of the driving spring 202b is in contact, and the driving spring 202b returns to the initial state, driving the base of the lock buckle 202a to rotate outward, driving the lock buckle 202a to rotate to the initial position, so that the lock buckle 202a and the switch cabinet are unlocked. Further, the staff controls the hydraulic rod 201a to retract inward, and the hydraulic rod 201a drives the electric operating arm 201b to retract inward. The electric operating arm 201b pulls the pushing rod 201c to move synchronously in the same direction to the initial position. Further, the staff pulls the switch trolley bracket 101a to the trolley storage position through the handle 101d to complete the maintenance.

[0045] In summary, the present invention drives the switch cabinet to move smoothly out of the experimental position through the electric operating arm 201b, the pushing rod 201c and the lock 202a, and assists the switch cabinet to completely enter the inner side of the switch trolley bracket 101a through the guide rail 101b-2. The electric operating arm 201b is folded to assist the switch cabinet to be prevented from tipping over during transportation, thereby preventing the switch cabinet from tipping over due to improper operation when pulling out the switch cabinet, and avoiding the problem of personal injury or switch damage.
