Description

Technical Field

[0001] This utility model relates to the field of substation switching operation tools, specifically a special toolbox for switching operations. Background Technology

[0002] Currently, substation operation and maintenance switching operations require carrying multiple tools, including insulated boots, insulated gloves, insulated levers, voltage detectors, computer anti-misoperation lock keys, voice recorders, operation tickets, power recorders, grounding wires, red and black pens, operating cranks, and flashlights. It is impossible for one operator to carry all the tools, often requiring the assistance of multiple people. Furthermore, the tools are easily misplaced, significantly impacting operational efficiency in terms of tool carrying capacity.

[0003] Analysis of past switching operation data revealed that the current power outage time for a single line switching operation is approximately 20 minutes, while busbar switching operations often take more than an hour. The main time spent on these operations is spent on two main areas: installing grounding wires (32%) and preparing tools (40%). Further research showed that in most cases, only the operator and supervisor are present, making it difficult to carry all tools at once. Furthermore, the operation locations are often far from the tool room, resulting in significant time wastage during retrieving tools.

[0004] Utility model patent application number 201220141930.5 discloses a multi-functional trolley for switching operation, including a frame and wheels. A push handle is provided on one side of the frame. The frame is a three-layer frame structure. A tool tray is fixed at one end of the upper layer of the frame. A lighting box is provided inside the tool tray. A tool box is fixed between the upper and middle layers of the frame. A voltage detector plate with through holes and an operating handle plate are welded on the middle layer of the frame. A voltage detector slot and an operating handle slot are provided on the lower layer of the frame corresponding to the voltage detector plate and the operating handle plate. An insulating glove holder is fixed to the bottom layer of the frame directly below the tool tray. A grounding plate is fixed in the middle of the opposite side of the push handle of the frame.

[0005] This multi-functional cart can carry all tools at once and can be pushed by manpower to the vicinity of the work position, effectively saving working time for switching operations. However, the cart still has the disadvantage of being too large and having difficulty passing through sloping terrain or steps. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a special toolbox for switching operations. It features readily available raw materials, a simple manufacturing process, and effectively overcomes the problem of multi-functional trolleys struggling to traverse steep or stepped terrain.

[0007] To achieve the above technical objectives, the specific solution adopted by this utility model is as follows: a special toolbox for switching operations, including a box body and a shoulder strap set on the box body. The box body includes a first vertical plate, and a second vertical plate is vertically connected to each of the two long end faces of the first vertical plate. The two second vertical plates are located on the same side of the first vertical plate, and the shoulder strap is set on the other side of the first vertical plate.

A drawer is set inside the first chamber, and an operating crank storage position and an insulating glove rack are set inside the second chamber.

[0008] As an optimized solution for the aforementioned special toolbox for switching operations, the lower surface of the second horizontal plate is fixedly connected with an anti-slip block that restricts the drawer from disengaging from the first chamber.

[0009] As an optimized solution for the aforementioned special toolbox for switching operations, the drawer is connected to the first chamber via a slide rail.

[0010] As an optimized solution of the above-mentioned special toolbox for switching operation, the storage position of the operating handle is an opening-up accommodating chamber, which is surrounded by the upper surface of the second horizontal plate and multiple steel pipes fixedly connected to it end to end.

[0011] As an optimized solution to the aforementioned switching operation toolbox, the insulating glove frame includes a horizontal bar connected to the upper surface of the steel pipe and a vertical bar connected above the horizontal bar.

[0012] As an optimized solution for the aforementioned special toolbox for switching operations, a slide rail is provided between the steel pipe and the crossbar.

[0013] As an optimized solution for the aforementioned special toolbox for switching operations, the steel pipe includes two longitudinal steel pipes and two transverse steel pipes, and there are two slide rails respectively set on the two longitudinal steel pipes.

[0014] As an optimized solution for the aforementioned switching operation toolbox, the crossbar is provided with multiple upward-facing mounting holes spaced apart along its length.

[0026] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the fastening method of the insulating pull rod buckle and the voltage detector buckle.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a special toolbox for switching operations, including a box body and a shoulder strap 12 set on the box body. The box body includes a first vertical plate 1, and a second vertical plate 2 is perpendicularly connected to each of the two long end faces of the first vertical plate 1. The two second vertical plates 2 are located on the same side of the first vertical plate 1. The first vertical plate 1 and the second vertical plate 2 are both rectangular structural boards made of balsa wood and have the same thickness. The connection method between the first vertical plate 1 and the second vertical plate 2 can be adhesive, screw connection or other effective connection methods. In this embodiment, the adhesive method commonly used by woodworkers is adopted.

[0029] Within the semi-enclosed space formed by the connection of the first vertical plate 1 and two second vertical plates 2, a first horizontal plate 3 and a second horizontal plate 4 are arranged. The first horizontal plate 3 and the second horizontal plate 4 are parallel to each other. The lower surface of the first horizontal plate 3 is flush with the lower ends of the first vertical plate 1 and the second vertical plate 2. The second horizontal plate 4 is located above the first horizontal plate 3, forming a first chamber 5 at the lower part of the second horizontal plate 4 and a second chamber 8 at the upper part of the second horizontal plate 4. The first horizontal plate 3 and the second horizontal plate 4 are both rectangular structural plates made of balsa wood and have the same thickness. The first horizontal plate 3 is connected to the first vertical plate 1 and the second vertical plate 2 by adhesive bonding, screw connection, or other effective connection methods. In this embodiment, adhesive bonding is used for connection. The second horizontal plate 4 is also connected to the first vertical plate 1 and the second vertical plate 2 by adhesive bonding.

[0030] The first chamber 5 is equipped with a drawer 6, and the second chamber 8 is equipped with an operating crank storage space 9 and an insulated glove rack 10.

[0031] Drawer 6 is also made of balsa wood. Drawer 6 is installed in the first chamber 5 via two slides. The two slides are located on both sides of drawer 6 and connected to the inner wall of the corresponding second vertical plate 2. The drawer opens and closes smoothly. The slides that control the opening and closing of the drawer are commercially available products, and their installation method is existing technology, which will not be described in detail here.

[0032] To prevent drawer 6 from slipping out of the first chamber 5, an anti-slip block 7 is fixedly connected to the lower surface of the second horizontal plate 4. The anti-slip block 7 is located at the outer end of the second horizontal plate 4 on the side away from the first vertical plate 1. The anti-slip block 7 is connected to the second horizontal plate 4 by screws, which are screwed vertically into the lower surface of the anti-slip block 7 and then tightened into the second horizontal plate 4. Meanwhile, drawer 6 is rationally divided into sections for easy organization and categorization of small tools.

[0033] In other embodiments of this utility model, a T-shaped pin (not shown in the figure) is rotatably installed on the anti-slip block 7, and a strip hole for inserting the T-shaped pin is provided on the drawer 6. When the drawer 6 is closed, the T-shaped pin is inserted into the strip hole, and rotating the T-shaped pin locks the drawer 6 in the first chamber 5, preventing the drawer 6 from opening when the user carries the toolbox.

[0034] The operating handle storage position 9 is an upward-opening accommodating chamber, formed by multiple steel pipes 14 connected end-to-end and fixedly connected to the upper surface of the second horizontal plate 4. In this embodiment, the steel pipes 14 are hollow square steel pipes, and there are four of them. The four steel pipes are connected vertically end-to-end and glued to the upper surface of the second horizontal plate 4. Specifically, the four steel pipes are two longitudinal steel pipes and two transverse steel pipes. The two steel pipes 14 parallel to the second vertical plate 2 are longitudinal steel pipes, and the two steel pipes 14 parallel to the first vertical plate 1 are transverse steel pipes.

[0035] The insulating glove frame 10 includes a crossbar 15 connected to the upper surface of a longitudinal steel pipe and a vertical bar 16 connected above the crossbar 15. Both ends of the crossbar 15 are fixedly connected to two longitudinal steel pipes, and the crossbar 15 is parallel to the vertical plate 1. In this embodiment, both ends of the crossbar 15 are welded to the middle of the two longitudinal steel pipes, achieving a reliable and effective connection through welding. In other embodiments of this invention, both ends of the crossbar 15 can also be fixed to two transverse steel pipes, making the crossbar 15 perpendicular to the vertical plate 1.

[0036] The vertical bars 16 on the horizontal bar 15 are used to stabilize and fix the insulating gloves, ensuring that the insulating gloves are clean, dry and easy to handle. Generally, there are two vertical bars 16, which can hold one pair of insulating gloves for easy use. Considering that there may be scenarios where multiple pairs of insulating gloves need to be used, multiple upward-facing mounting holes 17 are also provided on the horizontal bar 15 along its length. In the case where multiple pairs of insulating gloves need to be used, vertical bars that cooperate with them can be installed on the mounting holes 17 to increase the number of insulating gloves that the insulating glove rack 10 can hold.

[0037] like Figure 5As shown, the shoulder strap 12 is located on the outside of the first vertical plate 1. The shoulder strap 12 adopts a double shoulder strap carrying form. The shoulder strap width is moderate, conforms to ergonomics, reduces shoulder pressure, and the shoulder strap length is adjustable, which is convenient and comfortable to carry. At the same time, it improves the load-bearing capacity, frees the operator's hands, and facilitates the operator to perform switching operations.

[0038] like Figure 3 , Figure 4 As shown, the outer side of the second vertical plate 2 is provided with an insulating pull rod buckle 11 and an electroscope buckle 13. One of the second vertical plates 2 has two insulating pull rod buckles 11 of the same height on its outer side, and the other second vertical plate 2 also has two electroscope buckles 13 of the same height on its outer side. Both the insulating pull rod buckle 11 and the electroscope buckle 13 are large-diameter buckles to ensure that the tools are firmly fixed and prevent them from falling.

[0039] The usage process of this utility model is as follows:

[0040] When preparing tools for switching operations, first open drawer 6 and put small tools such as a voice recorder, operation ticket, recorder, computer anti-misunderstanding lock key, and flashlight into drawer 6. Close drawer 6 and then place the operation crank in the operation crank storage position 9. Next, put the insulating gloves on the vertical bars 16 on the insulating glove rack 10, one insulating glove on each vertical bar 16. Then insert the insulating pull rod into the insulating pull rod buckle 11 and insert the voltage detector into the voltage detector buckle. Then the operator can carry the entire device on their back using the shoulder strap 12. After another operator checks the tools, the tool preparation for switching operations is completed.

[0041] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:

[0042] Example 2

[0043] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in the following: the crossbar 15 is connected to the longitudinal steel pipe via two slide rails, each mounted on the upper surface of one of the two longitudinal steel pipes (not shown in the figure). The slide rails are installed parallel to the second vertical plate 2. The crossbar 15 is vertically mounted on the two slide rails. The crossbar 15 and the vertical bar 16 connected to it can move together along the slide rails. In use, the crossbar 15 can be moved to the innermost end of the slide rail first, then the operating handle can be placed, and then the crossbar 15 can be moved to the middle of the slide rail, positioned directly above the operating handle storage position 9 to prevent the operating handle from falling. Furthermore, moving the crossbar 15 and the vertical bar 16 connected to it to the outer end of the slide rail also facilitates the placement or retrieval of insulating gloves.

[0044] As a specific arrangement of the slide rail in this embodiment, the slide rail includes a slide groove and a slider disposed in the slide groove. The slide groove is opened on the upper surface of the longitudinal steel pipe and is consistent with the length direction of the longitudinal steel pipe. The slider is disposed in the slide groove and is fixedly connected to the crossbar 15. Pulling the crossbar 15 can move the slider along the length direction of the slide groove, thereby adjusting the position of the insulating glove holder 10 above the operating crank storage position 9.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
