[0031] With the development of the electric power industry, the application of gas cabinets is becoming more and more extensive. The gas cabinet, also known as the high-voltage ring network cabinet, is a high-voltage switchgear. Its main function is to serve as a high-voltage power distribution device, suitable for various environments and applications. The installation of components in the gas cabinet is an important step for this type of product. The quality of the installation of components will directly affect the quality of this type of product.

[0032] In the related art, when workers install components inside the gas box, they must first install the gas box on the base and use the base as an operating platform for subsequent assembly. However, the position of the base is usually fixed, and the volume and weight of the gas box are relatively large, which makes it difficult for workers to install, and will affect the work efficiency and safety of the components installed in the gas box of the inflatable cabinet.

[0033] In order to solve the above-mentioned problems, the present application provides a tooling for assembling the air box of an inflatable cabinet. The embodiments of the present application are further described in detail below in conjunction with Figures 1-6.

[0034] Refer to Figure 1, which shows a side view schematic diagram of a tooling in an embodiment of the present application. An embodiment of the present application provides a tooling for assembling inside an air box of an inflatable cabinet, specifically a tooling for assembling an air box. The tooling for assembling inside an air box of an inflatable cabinet includes a support assembly 1 for providing structural support. The support assembly 1 includes a tooling frame 11 placed in an operating site, and at least one support beam 12 connected to the tooling frame 11. All the support beams 12 are parallel to each other and arranged at intervals, and together form a bearing surface V1 for bearing the air box to achieve lifting of the air box.

[0035] In the embodiment of the present application, only two support beams 12 arranged parallel to each other are installed on each tooling frame 11 as an example for illustration. It can be understood that in some other embodiments, the support beams 12 can also be set to three or more, and all the support beams 12 are parallel to each other and arranged at intervals, so that the formed bearing surface V1 has a stronger load-bearing capacity, thereby improving the structural stability and assembly safety of the assembly tooling.

[0036] As shown in FIG2 , FIG2 is a schematic diagram of the tooling after the air box is lifted in one embodiment of the present application. The tooling also includes a lifting assembly 2 installed between the tooling frame 11 and the support beam 12. Driven by the lifting assembly 2, the support beam 12 can be lifted and moved along the first direction F1 relative to the tooling frame 11 to drive the air box placed on the bearing surface V1 to move to a suitable height, so that the staff can assemble parts inside and at the bottom of the air box, thereby improving the work efficiency and safety of the installation of components in the air box of the inflatable cabinet.

[0037] Furthermore, in order to ensure the operating safety of the workers during the lifting and assembly of the gas box, the tooling for assembling the gas box in the inflatable cabinet provided in one embodiment of the present application also includes a clamping assembly 3, and the clamping assembly 3 includes at least one pair of relatively arranged claws.

[0038] In some embodiments, the clamping assembly 3 only includes a pair of relatively arranged claws, and the pair of claws are arranged one-to-one corresponding to the two support beams 12 mentioned above, and can be clamped together on the outer wall of the air box to fix the horizontal position of the air box, thereby avoiding abnormal displacement or even falling of the air box during lifting or assembly, ensuring the safety of the use of the tooling, and thereby improving the operating safety of the staff.

[0039] Taking FIG. 1 and FIG. 2 as examples, in some other embodiments, the clamping assembly 3 includes two groups of claws, and the same group of claws is provided with two claws, and the claws are arranged relatively along the arrangement direction of the support beam 12, so as to be clamped together on the outer wall of the air box to fix the position of the air box in the horizontal direction. It can be understood that in some other embodiments, the clamping assembly 3 can also include three or more groups of claws to further improve the clamping stability of the air box and ensure the safety of the operator's operation.

[0040] In some other embodiments, when a plurality of support beams 12 are arranged on a fixture frame 11, the claws can be connected to the support beams 12 in a detachable manner. That is, according to the actual size of the air box to be assembled, two support beams 12 with corresponding spacing are selected for the installation of the claws, so that the claws can always abut against the outer wall of the air box to achieve transverse fixation of the air box.

[0041] Specifically, the claw and the support beam 12 can be detachably connected by means of a structure such as a clamp, a clamp or a bolt connection. As long as the claw can be detachably fixed to the support beam 12 and a certain force is provided for the claw to abut against the air box to achieve limiting force, the specific detachable connection structure between the claw and the support beam 12 is not limited in the embodiment of the present application.

[0042] Referring to FIGS. 1 to 4 , FIG. 3 shows a front view schematic diagram of a tooling in an embodiment of the present application, and FIG. 4 shows a schematic diagram of an air box clamping in an embodiment of the present application. In some embodiments, the lifting assembly 2 includes a driving member 21, a lead screw 22, a connecting member 23 and a guide assembly 24, wherein the driving member 21 is fixedly mounted on the top of the tooling frame 11, and in the embodiment of the present application, the driving member 21 can specifically be a driving motor. The lead screw 22 extends along the first direction F1 and is transmission-connected to the output shaft of the driving member 21, and one end of the lead screw 22 away from the driving member 21 is rotationally mounted on the tooling frame 11 to realize the movable installation of the lead screw 22. The connecting member 23 is transmission-connected between the above-mentioned support beam 12 and the lead screw 22, and the guide assembly 24 is movably connected to the connecting member 23 and is used to prevent the connecting member 23 from rotating around the lead screw 22, so that the connecting member 23 and the support beam 12 can be driven by the drive motor and the lead screw 22 to move up and down along the first direction F1.

[0043] During the actual assembly process, the staff first drives the drive member 21 to rotate the lead screw 22, thereby moving the support beam 12 to the bottom end of the tooling frame 11 through the connecting member 23, so that the staff can place the air box on the load-bearing surface V1 for subsequent assembly; then, the staff adjusts the clamping assembly 3 so that a pair of claws are clamped together on the outer wall of the air box to fix the position of the air box on the load-bearing surface V1; finally, according to the assembly requirements, the staff starts the drive member 21 again, and the lead screw 22 rotates in the opposite direction under the drive of the drive member 21, and moves the support beam 12 along the first direction F1 to a suitable position on the tooling frame 11 through the connecting member 23 to adapt to the assembly height requirements of the staff.

[0044] Specifically, the connecting member 23 includes a support frame 231 and a threaded member 232, all the support beams 12 are fixedly connected to one side wall of the support frame 231, and the threaded member 232 is connected to the other side wall of the support frame 231, so as to connect the support frame 231 to the above-mentioned lead screw 22. In the embodiment of the present application, the threaded member 232 and the lead screw 22 are threadedly matched, so that the threaded member 232 can be driven by the driving member 21 and the lead screw 22 to move up and down along the first direction F1, thereby driving the air box fixed on the bearing surface V1 to move up and down along the first direction F1 to adapt to the assembly requirements.

[0045] 1, the guide assembly 24 includes a guide rail 241 and a guide member 242. The guide rail 241 extends along the first direction F1 and is installed on the above-mentioned tooling frame 11, and the guide member 242 is connected to the above-mentioned threaded member 232. In the embodiment of the present application, the guide member 242 is specifically a slider, and is configured to be slidably installed in the guide rail 241 along the first direction F1 to achieve rotational limit of the threaded member 232, so that the threaded member 232 can be driven by the lead screw 22 to move up and down along the first direction F1.

[0046] Furthermore, in some other embodiments, the assembly tooling for the gas cabinet gas box also includes a limit assembly 4 for controlling the travel of the lifting assembly 2 in the first direction F1, and the limit assembly 4 includes an upper limit unit 41 and a lower limit unit 42 arranged at intervals along the first direction F1, wherein the upper limit unit 41 corresponds to the upper limit position of the lifting assembly 2, and is used to detect whether the lifting assembly 2 has reached the upper limit position; the lower limit unit 42 corresponds to the lower limit position of the lifting assembly 2, and is used to detect whether the lifting assembly 2 has reached the lower limit position.

[0047] In the embodiment of the present application, the upper limit unit 41 and the lower limit unit 42 are both communicatively connected to the above-mentioned driving member 21. When the support frame 231 drives the air box to the upper limit position or to the lower limit position, the upper limit unit 41 or the lower limit unit 42 detects the position of the lifting component 2, and triggers a power-off signal to be transmitted to the driving member 21 accordingly, so that the driving member 21 is actively powered off, thereby preventing the lifting component 2 from continuing to rise or fall, thereby ensuring the safety of the equipment.

[0048] As shown in Figure 3, in some embodiments, the assembly tooling for the air box of the inflatable cabinet also includes a controller 5, and the controller 5 is communicatively connected to the above-mentioned driving member 21 to realize the start and stop control of the driving member 21, so that the staff can use the controller 5 to actively switch the operating state of the driving member 21, so that the lifting assembly 2 can lift the air box to a suitable assembly position, thereby improving the assembly efficiency.

[0049] In the embodiment of the present application, the controller 5 includes a mounting bracket and a control panel, wherein the mounting bracket and the tooling frame 11 are arranged at intervals, and a certain safety distance is left between the two, so that the staff can evacuate to a safe position after completing the fixing and assembly of the gas box and then control the drive member 21 to start, so as to ensure the safety of the staff's operation. The control panel is installed on the top of the mounting bracket, and a signal transceiver device (not shown) is arranged inside it. The signal transceiver device and the control member are connected by wires or wireless signals to realize communication, so that the staff can control and switch the start and stop state of the drive member 21 in a safe area, thereby improving the efficiency of gas box assembly while effectively ensuring the personal safety of the staff.

[0050] Referring to Figures 5 and 6, Figure 5 shows a schematic diagram of the expansion of the support beam 12 in one embodiment of the present application, and Figure 6 shows a schematic diagram of the folding of the support beam 12 in one embodiment of the present application. In some embodiments, the support beam 12 is configured to be able to rotate toward the tooling frame 11, so that the support beam 12 is folded when the tooling is not working, thereby reducing the overall footprint of the tooling for assembling the gas box of the inflatable cabinet.

[0051] Specifically, the support beam 12 includes a fixed section 121, a rotating section 122 and a rotating member 123 that is transmission-connected between the fixed section 121 and the rotating section 122. The fixed section 121 is connected to the above-mentioned tooling frame 11 by means of a lifting assembly 2. Under the drive of external force, the fixed section 121 can rotate around the rotating member 123 toward the tooling frame 11 to achieve folding.

[0052] In the embodiment of the present application, when the central axis of the fixed section 121 coincides with the central axis of the rotating section 122, the dimensions of all the support beams 12 in the longitudinal direction are the same. In addition, in order to achieve a better folding effect, there is a size difference between the dimensions of two adjacent fixed sections 121 in the longitudinal direction, and the size difference is at least the radial dimension of one rotating section 122, so that the two adjacent support beams 12 can be folded and embraced together without spatial interference, thereby reducing the overall footprint of the tooling for assembling the gas box of the inflatable cabinet.

[0053] In some other embodiments, the support beam 12 only includes a rotating section 122 and a rotating member 123, and the rotating section 122 is rotatably mounted on the support frame 231 of the lifting assembly 2 by means of the rotating member 123. When the assembly tool for the gas cabinet gas box is not working, the fixed section 121 can be turned around the rotating member 123 toward the top of the tool frame 11 under the drive of external force, and the support beam 12 can also be folded to reduce the floor space occupied by the assembly tool for the gas cabinet gas box.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
