DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 7 As shown, a quick assembly device for a transformer insulation protective cover includes a positioning block 101, a mounting plate 103, a mounting column 104, a force rod 105 and a breakaway plate 109. The positioning block 101 is a C-shaped structure with an opening facing right. The positioning block 101 is a hollow structure. Circular adsorption holes 101a are evenly distributed on the inner wall of the positioning block 101. Suction holes 101b are symmetrically distributed on the outer wall of the positioning block 101. Suction holes 101b are all connected to suction pipes 102. The mounting plate 103 is horizontal. Fixed on the upper side of the positioning block 101, the mounting column 104 is provided with a pair and is vertically welded to the upper side of the mounting plate 103 symmetrically front and back, the force rod 105 is provided with a pair and is horizontally hinged to the two mounting columns 104 symmetrically front and back, the left section of the force rod 105 is slidably connected with a mounting tube 107, the upper side of the mounting tube 107 is threadedly connected with a hand screw 108 in the center, the split piece 109 is a "𠃎" type structure, the split piece 109 is provided with a pair and is symmetrically fixed to the side walls of the two mounting tubes 107 front and back.

[0024] In this embodiment, a pair of anti-slip sleeves 106 are further included, and the two anti-slip sleeves 106 are correspondingly sleeved on the right ends of the two force-applying rods 105. The anti-slip sleeves 106 are added to increase the friction force of the user's palm when holding the force-applying rod 105.

[0025] In this embodiment, a pair of heating blocks 110 are also included. The two heating blocks 110 are connected to the bends of the two split pieces 109 respectively. A heating rod 111 is inserted in the center of the heating block 110. A heat insulating sheet 112 is installed at the connection between the heating block 110 and the split piece 109. By installing a heating block 110 with a heating rod 111 to heat both sides of the process slit 115a on the transformer insulation protection cover 115, the difficulty of splitting and assembling is reduced. At the same time, by installing a heat insulating sheet 112 between the two, the heat of the heating block 110 is prevented from being transferred to the split piece 109, which would cause the split piece 109 to be burned or deformed when in contact with the transformer insulation protection cover 115.

[0026] In this embodiment, a limiting piece 113 is also included. The limiting piece 113 is of V-shaped structure and is opened to the right. The limiting piece 113 is horizontally welded to the left side of the mounting piece 103. Both ends of the limiting piece 113 are vertically connected to compression springs 114. The other ends of the two compression springs 114 are correspondingly pressed against the left sections of the two force-applying rods 105. By installing the limiting piece 113 and the compression springs 114 thereon, the process slit 115a on the transformer insulation protection cover 115 is always located in the middle of the two split pieces 109.

[0027] The quick assembly device for the transformer insulation protection cover includes the following steps when actually used:

[0028] Step 1: Loosen the hand screw 108 first, and then move the mounting tube 107 as far as possible to the right of the force rod 105;

[0029] Step 2: Install a transformer insulation protection cover 115 on the inner side of the positioning block 101, and make the process slit 115a on the transformer insulation protection cover 115 be located in the middle of the two broken pieces 109, and firmly absorb the transformer insulation protection cover 115 through the negative pressure condition formed at the adsorption hole 101a on the positioning block 101;

[0030] Step 3: Move the installation tube 107 as far as possible to the left of the force-applying rod 105, and insert the lower ends of the two split pieces 109 into the inner side of the process slit 115a on the transformer insulation protection cover 115, and then tighten the hand screw 108;

[0031] Step 4: The two sides of the process slit 115a on the transformer insulation protection cover 115 are heated remotely by the heating block 110 with the heating rod 111;

[0032] Step 5: Move the entire quick assembly device and the transformer insulation protection cover 115 thereon to the top of the transformer, and then use both hands to simultaneously move the two force-applying rods 105 outwards, and simultaneously drive the two breakaway pieces 109 to unfold along the process slits 115a on the transformer insulation protection cover 115, and then put the unfolded transformer insulation protection cover 115 onto the wiring of the transformer;

[0033] Step 6: Use both hands to simultaneously retract the two force rods 105 inward, temporarily disconnect the negative pressure gas source connected to the suction pipe 102, and then lift the entire quick assembly device upward and detach it from the transformer insulation protective cover 115.

[0034] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
