Description

Technical Field

[0001] The utility model relates to the technical field of air box casing installation, in particular to a special machine for automatically turning over the casing of an air box by 90 degrees for installation. Background Art

[0002] In order to improve the reliability of power supply and enable users to obtain power from two directions, the power supply network is usually connected in a ring. This power supply method is referred to as ring network power supply. In the AC 10kV distribution system of industrial and mining enterprises, residential areas, ports and high-rise buildings, due to the small load capacity, the high-voltage circuit is usually controlled by load switches or vacuum contactors and equipped with high-voltage fuse protection. The system is usually powered by a ring network, and the high-voltage switchgear used is generally called a ring network cabinet. Among them, the inflatable cabinet is a new type of switchgear that has developed rapidly in recent years. It installs the high-voltage electrical appliances of each functional unit in a sealed stainless steel box. The gas box uses a high-quality 3mm thick stainless steel shell. The stainless steel sheet is formed by laser cutting and welded by a welding manipulator to ensure the airtightness of the gas box. The box is filled with sulfur hexafluoride insulating gas above atmospheric pressure, so that it can be used reliably under harsh conditions (such as moisture, condensation, dirt, high altitude and chemical substances, etc.), and can greatly reduce the size and floor space, which is popular with users.

[0003] In the process of producing the air box, there is a step of fixing the sleeve on the air box by screw connection. The existing operation requires two workers. One person extends the sleeve into the corresponding position of the air box from the back and holds it, and the other person screws the sleeve on the front of the air box. Although this method can complete the installation of the sleeve, two workers are required during the installation process, which consumes a lot of manpower. In addition, the workers screw the screws horizontally, which causes the screws to fall frequently, reducing efficiency. Utility Model Content

[0033] The clamping assembly 6 includes a mounting cross frame 61 arranged at the rear of the workbench 2, which is used to install a quick clamp 62. The quick clamp 62 is fixed on the mounting cross frame 61. The model of the quick clamp 62 can be GH-304EM, but is not limited to this. The quick clamp 62 can drive the compression rubber pad 63 to press the sleeve 200 on the air box 100. The number of quick clamps 62 is the same as the number of sleeves 200; the clamp end of the quick clamp 62 is connected with a compression rubber pad 63 for compressing the sleeve 200; the left and right ends of the mounting cross frame 61 are fixed with mounting vertical frames 64, and the push rod of the first telescopic cylinder 7 is fixed to the mounting vertical frame 64. The first telescopic cylinder 7 can drive the mounting vertical frame 64 to move forward and backward, thereby driving the quick clamp 62 on the mounting cross frame 61 to move forward and backward.

[0034] A U-shaped block 65 is fixed on the mounting cross frame 61, and a flip block 67 is connected to the U-shaped block 65 via a pin shaft 66, so that the flip block 67 can be flipped on the U-shaped block 65, and a channel 68 for the pin shaft 66 to pass through is opened on the flip block 67. When flipping is required, the flip block 67 is pulled forward so that the pin shaft 66 hits the inner wall of the rear side of the channel 68, and then the flip block 67 is rotated; an adjustment block 610 is fixed to the front end of the flip block 67 via a quick latch 69, and the model of the quick latch 69 can be VCN120-8-35 self-locking, but is not limited to this. The flip block 67 has a plurality of fixing holes that cooperate with the quick latch 69 for adjusting the position of the adjustment block 610, so that the position of the quick clamp 62 can be adjusted to adapt to the installation of sleeves 200 of different specifications; the quick clamp 62 is fixed to the top of the adjustment block 610.

[0036] The rotating assembly 3 includes a fixing seat 31 fixed to the left and right ends of the workbench 2;

[0037] A first support frame 32 and a second support frame 33 are fixed on the base 1 on one side. The first support frame 32 is connected to the upper end fixed frame 311 of the fixed seat 31 via a worm gear slewing bearing 34. The worm gear slewing bearing 34 can easily drive the fixed seat 31 to rotate, thereby driving the workbench 2 to rotate. The model of the worm gear slewing bearing 34 can be WEA9-62-BH-R but is not limited to this; a reduction motor 35 is fixed on the second support frame 33, and a first sprocket (not shown) is fixed on the output shaft of the reduction motor 35.

[0040] The working principle of this embodiment is as follows: the first telescopic cylinder 7 drives the mounting vertical frame 64 to move backward, thereby driving the quick clamp 62 on the mounting horizontal frame 61 to move backward; the air box 100 is hoisted onto the workbench 2 and the support plate 8, so that the positioning pin 4 is inserted into the positioning hole of the bracket on the air box 100, and the quick clamp 62 is retracted by the first telescopic cylinder 7;

[0041] Open the quick clamp 62 to drive the compression rubber pad 63 to move backward, then pull the flip block 67 forward to make the pin shaft 66 hit the inner wall of the rear side of the channel 68, then rotate the flip block 67 upward, and then install the sleeve 200 into the mounting hole of the air box 100, flip the flip block 67 downward to a horizontal position, and then push the flip block 67 backward to make the pin shaft 66 hit the inner wall of the front side of the channel 68. After the flip block 67 is in place, it is stuck and will not move. The worker holds the sleeve 200 with one hand and presses the quick clamp 62 downward with the other hand, so as to drive the compression rubber pad 63 to move forward and press the sleeve 200;

[0042] After all the sleeves 200 are pressed, the worm gear slewing bearing 34 is started by the reduction motor 35, thereby driving the fixing seat 31 to rotate upward 90°, so that the quick clamp 62 is located below the air box 100, and then the second telescopic cylinder 12 is started to drive the rack 13 to move forward, thereby driving the gear 14 to rotate, thereby driving the second rotating shaft 15 to rotate, and then driving the support plate 8 to rotate downward 180° to prevent the support plate 8 from obstructing the worker's operation;

[0043] Finally, the sleeve 200 is fixed to the air box 100 by screws.

[0044] In one embodiment of the utility model, an L-shaped block 611 is fixed to the clamp end of the quick clamp 62, and a compression rubber pad 63 is connected to the L-shaped block 611 via a spring 612, so that the compression rubber pad 63 can play a buffering role when the sleeve 200 is compressed to prevent the sleeve 200 from being crushed; the spring 612 ensures that the compression rubber pad 63 will not press the sleeve 200 too tightly, and the sleeve 200 can be rotated by hand when the sleeve 200 is misplaced, so as to facilitate the locking of the screw; the rear side of the compression rubber pad 63 is located in the spring 612 and a guide rod 613 is fixed thereto, and the rear end of the guide rod 613 penetrates the L-shaped block 611, and the guide rod 613 can play a limiting and guiding role when the compression rubber pad 63 is applied to the sleeve 200.

[0045] In one embodiment of the utility model, a third telescopic cylinder 16 is fixed in the support frame 312, and a push rod of the third telescopic cylinder 16 penetrates the support frame 312 and fixes a limit block (not shown in the figure). The support plate 8 has a limit groove (not shown in the figure) for inserting the limit block. The third telescopic cylinder 16 can drive the limit block to be inserted into the limit groove, so that the air box 100 can be better supported.

[0046] The telescopic cylinder, reduction motor and linear bearing in the utility model are all prior art, and those skilled in the art are already well aware of them, so they will not be described in detail here. The utility model protects the structural features of the special machine for automatically turning the air box 90° for installing the casing.
