[0039] Please see the appendix Figure 1-6 An embodiment of the present invention provides an installation, commissioning, and transportation device for a high-voltage disconnector switchgear box 50, comprising a fixing component 10, a height adjustment mechanism 20, and two support components 30 arranged laterally opposite each other. First, it should be noted that in this application, "lateral" refers to the width direction of the overall device, and "longitudinal" refers to the length direction of the overall device. Please refer to the accompanying drawings for details; the specific design is as follows:

[0040] The fixing assembly 10 includes two fixing rods 110 and at least one quick-release fixing rod 120. Each support assembly 30 includes a first diagonal brace 310, a second diagonal brace 320, and a support rod 330. The first diagonal brace 310 and the second diagonal brace 320 are hinged together to adjust the support height of the support assembly 30. The support rod 330 is connected to the top of the support assembly 30. The two ends of the two support rods 330 are connected by the fixing rods 110 extending laterally. The two ends of the quick-release fixing rod 120 are respectively engaged with the two fixing rods 110. On the support rod 330, the two support rods 330 and the two fixing rods 110 together form a placement space, and the quick-release fixing rod 120 divides the placement space into multiple placement units; the height adjustment mechanism 20 is connected above the cross hinge point of the first diagonal brace 310, and the drive end of the height adjustment mechanism 20 is connected above the cross hinge point of the second diagonal brace 320, and the drive end of the height adjustment mechanism 20 is set to be tightened / untightened; wherein, when the drive end of the height adjustment mechanism 20 is gradually tightened, the height of the support assembly 30 increases.

[0041] Specifically, the installation, commissioning and transportation device for the high-voltage disconnector mechanism box 50 in this application includes a fixing component 10, a height adjustment mechanism 20 and two support components 30 arranged laterally opposite each other. The fixing component 10 is used to connect the two support components 30 to form a whole and share the force. The height adjustment mechanism 20 is used to adjust the height of the support components 30 so as to adjust the high-voltage disconnector mechanism box 50 installed on the support components to the required height, thereby facilitating maintenance and commissioning.

[0042] Each of the support components 30 includes a first diagonal brace 310, a second diagonal brace 320, and a support rod 330. The two diagonal braces are hinged together. Since the bottom is placed on the ground, when the tops of the first diagonal brace 310 and the second diagonal brace 320 approach each other, the tops of the first diagonal brace 310 and the second diagonal brace 320 gradually rise. Consequently, the position of the support rod 330, mounted on the tops of the first diagonal brace 310 and the second diagonal brace 320, also rises, adjusting the height of the high-voltage disconnector mechanism box 50 mounted on the support rod 330. Furthermore, the two ends of the oppositely positioned support rod 330 are respectively provided with the fixed... The fixed rod 110 can have a transverse through hole to allow the fixed rod 110 to pass through and achieve a transverse connection and fixation effect. The quick-release fixed rod 120 is used to further fix the middle range between the two support rods 330 and improve the transverse strength. Unlike the fixed rod 110, the quick-release fixed rod 120 is snapped onto the support rod 330, which makes disassembly and assembly more convenient and allows for quick disassembly and assembly. It is worth mentioning that the quick-release fixed rod 120 can also divide the placement space into multiple placement units for multiple high-voltage disconnect switch mechanism boxes 50 to be placed and installed separately. The specific number of placement units depends on the number of quick-release fixed rods 120.

[0043] Furthermore, the height adjustment mechanism 20 is used to adjust the opening degree of the support assembly 30. It is located above the cross hinge point of the first diagonal brace 310, and its drive end is connected to the cross hinge point of the second diagonal brace 320. Thus, by tightening / relaxing, the opening degree of the upper section of the support assembly 30 at the cross hinge point is controlled, thereby achieving the effect of height adjustment. Specifically, when the drive end of the height adjustment mechanism 20 is gradually tightened, it pulls the upper section of the second diagonal brace 320 closer to the upper section of the first diagonal brace 310 around the cross hinge point (i.e., the upper sections move closer together), thereby increasing the overall height. Please refer to the appendix for details. Figure 5 As shown in the figure; when the drive end of the height adjustment mechanism 20 gradually relaxes, its tension gradually disappears. At this time, the support component 30 can be manually adjusted, or the support component 30 can be adjusted back to its initial state under the action of gravity of the high voltage disconnect switch mechanism box 50.

[0044] In a preferred embodiment of the present invention, the first diagonal brace 310 includes two diagonal braces arranged laterally opposite each other, and the second diagonal brace 320 passes through the two diagonal braces to be intersected and hinged with the first diagonal brace 310 by a pin.

[0045] It should be noted that by differentiating the two types of diagonal bracing structures, the first diagonal bracing 310 consists of two diagonal braces spaced apart, while the second diagonal bracing 320 is a single rod that passes between the two diagonal braces and connects the intersection point with a pin. This makes installation convenient and improves the stability of the interlocking structure.

[0046] In a preferred embodiment of the present invention, the support rod 330 includes a first support section 331 and a second support section 332. The width of the first support section 331 is smaller than the width of the second support section 332. The first support section 331 has a first groove extending longitudinally, and the second support section 332 has a slide rail extending longitudinally. A second slide rail is also provided on both sides of the slide rail. The two diagonal rods of the first diagonal brace 310 are respectively disposed on both sides of the first support section 331 and are slidably connected to the first support section 331 by a pin passing through the first slide rail. The top end of the second diagonal brace 320 extends into the slide rail and is slidably connected to the second support section 332 by a pin passing through the top end of the second diagonal brace 320 and being placed in the second slide rail.

[0047] It should be noted that since the first diagonal brace 310 and the second diagonal brace 320 have different structural forms, the corresponding connection structures at both ends of the support rod 330 are also different to facilitate installation. Specifically, it includes a first support section 331 and a second support section 332. The first support section 331 has a smaller width to facilitate connection between the two diagonal braces of the first diagonal brace 310. It also has a first sliding groove so that the pin passes through the top ends of the two diagonal braces and then passes through the first sliding groove simultaneously. The first diagonal brace 310 rotates around the cross hinge point. When the top support rod 330 is connected, the position changes adaptively to avoid rigid failure. Similarly, the second support section 332 is wider and has a slide rail for the top of the second diagonal brace 320 to be inserted and placed. The connection is made by a pin, with both ends of the pin extending out of the top of the second diagonal brace 320 to be placed in the second slide rails on both sides. When the second diagonal brace 320 rotates around the cross hinge point, the connection point between the second diagonal brace 320 and the second support section 332 also moves accordingly, thus utilizing the excellent adaptability of the hinge movement.

[0048] In a preferred embodiment of the present invention, the height adjustment mechanism 20 includes a transmission rod 210, a mounting box 220, a pawl 230, a ratchet 240, a return spring 250, and two fixing plates 260 arranged laterally opposite each other. The driving end of the height adjustment mechanism 20 is a steel wire rope 270. The two fixing plates 260 are respectively connected above the cross hinge points of the two first diagonal braces 310. The mounting box 220 is fixed to one of the fixing plates 260. The pawl 230, ratchet 240, and return spring 250 are all built into the mounting box 260. In the mounting box 220, the transmission wheel passes through the ratchet 240, the mounting box 220, and the fixing plate 260 and is connected to another fixing plate 260. The transmission rod 210 is rotatably mounted. One end of the wire rope 270 is wound and connected to the transmission rod 210, and the other end of the wire rope 270 is connected to the second diagonal brace 320 on the same side. The two ends of the return spring 250 are respectively connected to the pawl 230 and the mounting box 220. The pawl 230 and the ratchet 240 mesh with each other to perform unidirectional intermittent rotation.

[0049] It is worth noting that the principle of using the rotating transmission rod 210 to wind the steel wire rope 270 to tighten the steel wire rope 270 and thus pull the second diagonal support rod 320 is achieved. Therefore, one end of the steel wire rope 270 is wound and connected to the transmission rod 210, and the other end of the steel wire rope 270 is connected to the second diagonal support rod 320 on the same side. It can be understood that, considering the synchronous pulling of the two support components 30, a set of steel wire ropes 270 is wound around each end of the transmission rod 210 to connect to the second diagonal support rod 320 on the same side. Holes can be made in the second diagonal support rod 320 for the steel wire ropes 270 to pass through and be fixed. The fixing plate 260 is used for... The mounting box 220 is used for housing the pawl 230, ratchet 240, and return spring 250. The pawl 230 and ratchet 240 achieve unidirectional intermittent rotation. Each rotation tightens the gear by one stop, limiting the movement through the interaction of the pawl 230, preventing it from reversing on its own, thus ensuring stability after adjustment. The return spring 250 is used to pull the pawl 230 back after the ratchet 240 rotates one tooth, ensuring a unidirectional limiting effect. These principles are well-known to those skilled in the art and will not be elaborated upon here; for easier understanding, please refer to the appendix. Figure 2 The example shown illustrates that each time the ratchet 240 is rotated counterclockwise, the ratchet 240 pushes the pawl 230 downward. After rotating one tooth, the pawl 230 is pulled back by the return spring 250 to lock the ratchet 240 (engaging with the ratchet 240). At this time, the two diagonal braces move closer to each other by a certain distance to raise the height to a certain level. If a higher height is required, the rotation continues until the target height is reached.

[0050] In a preferred embodiment of the present invention, there are two quick-release fixing rods 120, and each quick-release fixing rod 120 has a groove 123 recessed at both ends; wherein, the groove 123 of the quick-release fixing rod 120 located in the first support section 331 is matched with the first support section 331, and the groove 123 of the quick-release fixing rod 120 located in the second support section 332 is matched with the second support section 332.

[0051] It is worth noting that when two quick-release fixing rods 120 are used, the system is divided into three placement units, which can accommodate three high-voltage disconnector switch mechanism boxes 50. For details, please refer to the appendix. Figure 6 As shown in the figure; considering the segmented form of the support rod 330, the groove widths of the two quick-release fixing rods 120 need to be set differently during processing, that is, they correspond to the width of the support segment to be installed, so as to match each other and ensure the snap-fit ​​effect. The two support rods 330 are also mutually laterally limited by the action of the slot 123 to achieve the fixing effect. When disassembling and assembling, you can simply lift the quick-release fixing rod 120 upwards, which is quick and convenient.

[0052] Furthermore, the quick-release fixing rod 120 is slidably arranged longitudinally.

[0053] It should be noted that the length range of the placement unit can be adjusted by sliding along the longitudinal direction of the support section through the slot 123, so as to adapt to high-voltage disconnector mechanism boxes 50 of different lengths.

[0054] Furthermore, it also includes a lateral limiting component 40, which includes a fixing tube 410 and two limiting sleeve 420 units arranged laterally opposite each other. Each limiting sleeve 420 unit includes two limiting sleeves 420. The two ends of the fixing tube 410 are respectively provided to pass through and extend out of the two fixing plates 260. The two limiting sleeves 420 of each limiting sleeve 420 unit abut against the two sides of one of the fixing plates 260, and the limiting sleeves 420 are connected to the fixing tube 410 by bolts passing through the limiting sleeves 420 and abutting against the side wall of the fixing tube 410.

[0055] It should be understood that the lateral limiting component 40 is used to fix the lateral distance between the two support components 30 to fix the width of the entire device. The lateral distance between the two support components 30 can be adjusted according to the width requirements of the high-voltage disconnector mechanism box 50. After adjustment, it is fixed by the fixing component 10 and further limited and fixed by the lateral limiting component 40. Specifically, the fixing tube 410 passes through the two fixing plates 260. When adjusting the lateral distance, the fixing tube 410 can slide in the through hole of the fixing plate 260. After adjustment, the bolts on the limiting sleeve 420 are tightened and the fixing tube 410 is held to achieve fixation. Each fixing plate 260 is provided with a limiting sleeve 420 on both sides to ensure the lateral front and rear bidirectional limiting effect, which greatly improves the limiting and fixing ability.

[0056] Furthermore, the quick-release fixing rod 120 includes a connecting part 121 and two fixing parts 122 arranged laterally opposite each other. The slot 123 is formed at the bottom end of the fixing part 122. The fixing part 122 is engaged with the support rod 330 through the slot 123. The inner side of the two fixing parts 122 that are close to each other is recessed to form a blind hole. The two ends of the connecting part 121 are respectively inserted into the blind holes of the two fixing parts 122 to connect the two fixing parts 122. The end of the connecting part 121 is reserved with a lateral sliding gap in the blind hole.

[0057] It should be noted that, due to the adjustment of the lateral width of the entire device, the fixing rod 110 can slide within the opening, while the quick-release fixing rod 120, which is used for snap-fit ​​installation, cannot slide. Therefore, it can be configured such that the connecting part 121 cooperates with the two fixing parts 122. By adjusting the length of the connecting part 121 extending into the interior of the fixing part 122, the distance between the two fixing parts 122 can be shortened to adapt to the lateral width of the entire device. Therefore, the end of the connecting part 121 has a lateral sliding gap reserved in the blind hole. When it needs to be shortened, the two fixing parts 122 can be pressed together, so that the connecting part 121 can be further inserted into the blind hole.

[0058] Furthermore, it also includes casters 340, with each of the bottoms of the first diagonal brace 310 and the second diagonal brace 320 being hinged with a caster 340.

[0059] It should be noted that the caster 340 facilitates the transportation and movement of the entire device. It is worth mentioning that the caster 340 connected to the bottom end of the first diagonal brace 310 can adopt a single-ear plate structure and be hinged between the two diagonal braces, while the caster 340 connected to the bottom end of the second diagonal brace 320 can adopt a double-ear plate structure, so that the bottom end of the second diagonal brace 320 can be hinged between the double-ear plates.

[0060] Furthermore, the height adjustment mechanism 20 also includes a hand crank 280, the transmission rod 210 has a control end, the control end of the transmission rod 210 extends out of the mounting box 220, and the hand crank 280 is fixed to the control end of the transmission rod 210.

[0061] Understandably, the hand crank 280 is designed to facilitate operation by technicians, thereby improving ease of use and efficiency.

[0062] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
