Description

Technical Field

[0001] The present invention relates to the technical field of tank type circuit breakers, and in particular to an HMB-4 type hydraulic spring mechanism disassembly and assembly device. Background Art

[0002] Currently, common substations on the market utilize GIS and HGIS (gas-insulated, fully enclosed) combination units, also known as tank-type circuit breaker combination units. Due to various factors, including manufacturing quality, component precision, and long-term operation, these combination units suffer from low reliability and frequent failures. When a serious failure occurs in the HMB-4 hydraulic spring mechanism, the HMB-4 hydraulic spring mechanism must be replaced. The existing replacement method involves first passing a steel pipe through the upper ring of the HMB-4 hydraulic spring mechanism. Maintenance personnel then lift the HMB-4 hydraulic spring mechanism back and forth to suspend it in the air. The HMB-4 hydraulic spring mechanism is then lifted out of the switchgear, and the reverse process is repeated for reinstallation. This replacement method has the following shortcomings: 1) The shape of the HMB-4 hydraulic spring mechanism is irregular - the auxiliary switch, secondary wiring, opening and closing coils, and motor protrude in different directions, and the protruding parts are at a small distance from the inner wall of the switch cabinet. During manual lifting, they are easily bumped against the switch cabinet, causing the equipment damage characteristics to be unqualified; 2) The HMB-4 hydraulic spring mechanism needs to be raised above the threshold of the switch cabinet, but the lifting height cannot be accurately controlled manually. The lifting height needs to be continuously adjusted during the process, which is time-consuming and labor-intensive, and the replacement efficiency is low; 3) The irregular shape of the HMB-4 hydraulic spring mechanism causes the center of gravity to be not located at the geometric center of the HMB-4 hydraulic spring mechanism. During transportation, it will shake, further increasing the probability of collision and the difficulty of controlling the lifting height, further reducing the replacement efficiency.

[0092] The embodiment of the present invention provides an HMB-4 type hydraulic spring mechanism disassembly and assembly device, which is used to solve the technical problem that the replacement efficiency of the HMB-4 type hydraulic spring mechanism by manual handling in the prior art is low.

[0093] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

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

[0094] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0095] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections. They can also refer to direct connections or indirect connections through an intermediate medium. They can also refer to internal connections between two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0096] The existing replacement method of the HMB-4 hydraulic spring mechanism has the following shortcomings: 1) The shape of the HMB-4 hydraulic spring mechanism is irregular - the auxiliary switch, secondary wiring, opening and closing coils and motor protrude in different directions, and the protruding parts are at a small distance from the inner wall of the switch cabinet. During manual lifting, they are prone to collision with the switch cabinet, causing equipment damage characteristics to be unqualified; 2) The HMB-4 hydraulic spring mechanism needs to be lifted higher than the threshold of the switch cabinet, but the lifting height cannot be accurately controlled manually. The lifting height needs to be continuously adjusted during the process, which is time-consuming and labor-intensive, and the replacement efficiency is low; 3) The irregular shape of the HMB-4 hydraulic spring mechanism causes the center of gravity to be not located at the geometric center of the HMB-4 hydraulic spring mechanism. During transportation, it will shake, further increasing the probability of collision and the difficulty of controlling the lifting height, further reducing the replacement efficiency.

[0107] The beneficial effects of this embodiment include:

[0108] ① The HMB-4 hydraulic spring mechanism 600 is raised by the driving member 330 and limited by the connecting member 410 to avoid shaking during the pulling process. This allows for precise control of the raising height, saves time and effort during the assembly and disassembly process, and improves replacement and maintenance efficiency.

[0109] ② By rotating the rotating member 430 to drive the HMB-4 hydraulic spring mechanism 600 to rotate, the left and right door frames of the front door 510 can be avoided, thereby avoiding collisions during transportation and ensuring that the equipment damage characteristics are qualified.

[0110] In a preferred embodiment of the rotating assembly 400, the fourth bracket includes a first plate 311 perpendicular to the first direction. The first plate 311 defines a first arcuate through-hole 3111 and a second arcuate through-hole 3112, which extend through the first plate 311 along the first direction and are symmetrical about the rotation center of the rotating member 430. The connecting member 410 includes four connecting posts extending along the first direction; two connecting posts extend through the first arcuate through-hole 3111, and the other two extend through the second arcuate through-hole 3112. The first arcuate through-hole 3111 and the second arcuate through-hole 3112 limit the rotation angle of the rotating member 430, preventing large rotation angles. The provision of multiple connecting posts connects the rotating member 430 to the HMB-4 hydraulic spring mechanism 600, improving connection stability and ensuring more uniform force distribution on the HMB-4 hydraulic spring mechanism 600.

[0111] Exemplarily: the first flat plate 311 is a square plate structure, on which are provided two arc-shaped through holes perpendicularly passing through its upper and lower surfaces, namely the first arc-shaped through hole 3111 and the second arc-shaped through hole 3112, the extension curves of the two arc-shaped through holes on the upper surface of the square plate structure are located on the same circle, and the center of the circle is located at the center of the upper surface of the square plate structure; the upper surface of the square plate structure is fixedly connected to the outer ring of a ball bearing, and the straight line where the axis of the ball bearing is located passes through the center of the upper surface of the square plate structure, and the ball bearing is the rotating support member 420; the upper end face of the inner ring of the ball bearing is fixedly connected to the lower surface of a square plate structure, and the square plate structure is the rotating member 430, and the areas of the lower surface of the square plate structure corresponding to the two arc-shaped through holes are fixedly connected to the upper end faces of two connecting columns, and the two connecting columns connected in the same area are spaced parallel to each other.

When the hydraulic cylinder's drive shaft extends upward, partially penetrates the first through-hole of the second plate 312, and continues to extend upward, the second plate 312 is pushed upward, driving the fourth bracket to rise. The drive shaft then retracts downward, driving the fourth bracket to descend. By providing multiple connecting shafts 321 to connect the fourth bracket to the third plate 214, the force applied to the fourth bracket is more evenly distributed. The multiple connecting shafts 321 guide the fourth bracket's movement, improving its stability.

[0113] For example, the driving member 330 is a HOB50-125 oil cylinder; the fourth bracket further includes a square rod structure of A crossbeam 313, B crossbeam 314, C crossbeam 315, D crossbeam 316, E crossbeam 317, F crossbeam 318, A vertical beam 319 and B vertical beam 320; A crossbeam 313 and B crossbeam 314 have the same shape and are spaced parallel to each other, and the extension direction of A crossbeam 313 and B crossbeam 314 are parallel to the extension direction of the first guide rail 130. The extension direction of the C beam 315 is perpendicular to the extension direction of the A beam 313. One end of the C beam 315 is fixedly connected to the middle of the A beam 313, and the other end is fixedly connected to the middle of the B beam 314. The D beam 316 and the E beam 317 have the same shape and are spaced parallel. The extension directions of the D beam 316 and the E beam 317 are parallel to the extension direction of the first guide rail 130.

The number of circular connecting shafts 321 is 4; 4 circular third through holes extending along the first direction are opened on the third plate 214, and the centers of the openings of the 4 third through holes are connected in sequence to form a rectangle, 2 third through holes correspond to the A beam 313, and the other 2 third through holes correspond to the B beam 314; the second through hole is located in the area corresponding to the rectangle; the 4 connecting shafts 321 are respectively passed through the 4 third through holes; the upper end of the connecting shaft 321 is fixedly connected to the second plate 312, and the lower end is fixedly connected to the A beam 313 or the B beam 314. The ends of the A beam 313 and the B beam 314 corresponding to the third plate 214 are both two-level stepped structures, wherein the lower step is used to support the connecting shaft 321. At this time, the 4 connecting shafts 321 are pump tops, and the HOB50-125 oil cylinder is connected to the pump top through a four-way valve. The synchronous lifting and lowering of the 4 pump tops realizes the synchronous lifting and lowering of the fourth bracket, thereby preventing the fourth bracket from tilting due to uneven force.

[0114] A preferred embodiment of the sliding assembly 200: the third bracket also includes a first crossbeam 211, a second crossbeam 212 and a third crossbeam 213 with a square rod structure; the first crossbeam 211 and the second crossbeam 212 are spaced apart and parallel, and the extension directions of the first crossbeam 211 and the second crossbeam 212 are both parallel to the extension direction of the first guide rail 130; the first crossbeam 211 is connected to the first guide rail 130 through the first sliding member 220, and the second crossbeam 212 is connected to the second guide rail 140 through the second sliding member 230; the extension directions of the third crossbeam 213 and the first crossbeam 211 are perpendicular to each other, one end of the third crossbeam 213 is fixedly connected to the first crossbeam 211, and the other end is fixedly connected to the second crossbeam 212; the opposite ends of the third plate 214 are respectively fixedly connected to the first crossbeam 211 and the second crossbeam 212; the fourth bracket corresponds to the interval between the first crossbeam 211 and the second crossbeam 212.

[0115] A preferred embodiment of the first sliding member 220 and the second sliding member 230: the first sliding member 220 includes N first pulleys arranged at intervals along the extension direction of the second beam 212, where N is an integer greater than or equal to 1; the rotation center of the first pulley is perpendicular to the extension direction of the first beam 211 and the first direction; the second sliding member 230 includes N second pulleys arranged at intervals along the extension direction of the second beam 212; the rotation center of the second pulley is perpendicular to the extension direction of the second beam 212 and the first direction; the N first pulleys and the N second pulleys correspond one to one.

[0116] For example: the first crossbeam 211 is evenly spaced and connected with three No. 8 channel steel wheels, namely the first pulley, and the rotating shaft of the first pulley passes through the first crossbeam 211 and is rotatably connected to the first crossbeam 211; the second crossbeam 212 is evenly spaced and connected with three No. 8 channel steel wheels, namely the second pulley, and the rotating shaft of the second pulley passes through the second crossbeam 212; the rotation center of any first pulley is collinear with the rotation center of a second pulley; accordingly, the first guide rail 130 and the second guide rail 140 are both channel steel structures.

[0117] Optimized: The first bracket 110 is provided with a laser transmitter; the second bracket 120 is provided with a laser receiver, which corresponds to the laser transmitter; the laser transmitter and the laser receiver are used to detect whether the HMB-4 hydraulic spring mechanism 600 is aligned with the door of the switch cabinet 500; the third bracket is provided with a laser rangefinder for detecting the lifting distance between the fourth bracket and the fourth bracket.

[0118] For example, the first bracket 110 is provided with a first laser emitter and a second laser emitter. The laser emitted by the first laser emitter is flush with the right door frame of the front door 510 and the rear door 520 of the switch cabinet 500, and the laser emitted by the second laser emitter is flush with the left door frame of the front door 510 and the rear door 520 of the switch cabinet 500. The first bracket 110 is provided with a first laser receiver and a second laser receiver. The first laser receiver corresponds to the first laser emitter and can receive the laser emitted by the first laser emitter. The second laser receiver corresponds to the second laser emitter. It can receive the laser emitted by the second laser transmitter; when the laser receiver receives the laser emitted by the corresponding laser transmitter, it means that the HMB-4 hydraulic spring mechanism 600 is aligned with the front door 510 and can be moved out or in. When the laser receiver does not receive the laser emitted by the corresponding laser transmitter, it means that the HMB-4 hydraulic spring mechanism 600 is not aligned with the front door 510, an audible and visual alarm is issued, and the mechanism cannot be moved out or in. The HMB-4 hydraulic spring mechanism 600 needs to be rotated so that the raised part on it avoids the laser. The mechanism can be moved out or in only after the audible and visual alarm disappears. To ensure that the first and second guide rails 130 and 140 are aligned on the same horizontal plane, a level is installed on each of them. Adjustable feet 111 are installed at the bottom ends of the first and second brackets 110 and 120. These adjustable feet 111 contact the ground, allowing the heights of the first and second brackets 110 and 120 to be adjusted according to varying ground conditions. This allows the first and second guide rails 130 and 140 to be aligned on the same horizontal plane, adapting to uneven surfaces. Furthermore, the first and second guide rails 130 and 140 are designed to be assembled in sections, eliminating the problem of insufficient front-to-back clearance for passage through a switchgear cabinet. Furthermore, the first bracket 110 can be constructed with two separate supports, providing increased handling stability.
