DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] As shown in Figure 1 and Figure 2 An embodiment provided by the utility model: a pile clamping mechanism of a water surface power station maintenance platform, comprising a square tube 1, a rotating shaft 2, a sliding sleeve 6 and a pile clamping jaw 7; the square tube 1 is fixed horizontally on a ship deck; the lower part of the rotating shaft 2 is fixedly connected to the square tube 1; the sliding sleeve 6 is connected to the upper part of the rotating shaft 2, so that the sliding sleeve 6 rotates relative to the rotating shaft 2, and the sliding sleeve 6 is fixed in the upper, inner and lower directions of the rotating shaft 2 through plane bearings 3, copper sleeves 4 and cover plates 5; the pile clamping jaw 7 is inserted into the sliding square hole of the sliding sleeve 6 and can slide linearly in the middle of the sliding sleeve 6; the front opening of the pile clamping jaw 7 holds the cement column therebetween through linear and rotary operation, then the opening end is buckled by the swing arm 8, finally the check device 9 prevents it from loosening reversely, so that the cement column is locked between the pile clamping jaw 7 and the swing arm 8, then the rotating fixing screw of the sliding sleeve 6 and the linear motion fixing screw of the pile clamping jaw 7 are fixed by bolts, and two sets of pile clamping mechanisms are simultaneously operated to fix the iron ship and the entire maintenance platform, so that the iron ship and the entire maintenance platform cannot move horizontally and will not tip over, and the pile clamping mechanism is used for the maintenance of solar module, support, combiner box and other field equipment of a water surface photovoltaic power station.

[0021] Wherein, the square tube 1 is provided with openings on the upper and lower surfaces at one end position, and the rotating shaft 2 is fixedly connected to the two opening surfaces by welding. The square tube 1 has two functions, the first function is to strengthen the rigidity of the ship in the transverse direction. If the rotating shaft 2 is directly welded on the deck of the iron ship without the square tube 1, the deck is mostly made of steel plate, which is relatively thin, within 20mm. If the ship has the possibility of capsizing, the holding pawl 7 will generate a large torque, and the pawl will finally transmit the torque to the rotating shaft 2 and the deck steel plate fixedly connected with the rotating shaft 2, which may cause the deck to deform, thereby causing the elevator at a high place to tilt and cause danger. With the square tube 1, the rigidity of the deck is greatly strengthened, and the deck is not easy to deform. The rotating shaft is welded on the two surfaces in contact with the square tube 1, thereby strengthening the firmness of the welding.

[0022] In the preferred embodiment, as shown in Figure 3 The copper sleeve 4 is provided with a flange to reduce the friction when the sliding sleeve 6 rotates. The sliding sleeve 6 includes an upper iron plate 11, a lower iron plate, a first channel steel 12, a second channel steel 13, and a single third channel steel 14, which are connected by bolts and appropriate thickness gaskets to form the sliding sleeve 6. The first channel steel 12 and the second channel steel 13 are fixedly connected by butt welding and are processed with a through hole. The through hole passes through the copper sleeve 4 with a flange, and the copper sleeve 4 is connected with the first channel steel 12 and the second channel steel 13 by screws through the flange, which is equivalent to the copper sleeve 4 being embedded in the first channel steel 12 and the second channel steel 13. The third channel steel 14 is opposite to the groove direction of the second channel steel 13, and a square hole with four sides is formed between the third channel steel 14 and the second channel steel 13 through the upper iron plate 11 and the lower iron plate. The four sides of the square hole of the sliding sleeve 6 are fixed with ball bearings 15 parts by nuts, so that the pile holding pawl 7 can move freely therein. In addition, a plate-shaped rotation stop device 10 is also provided on the square tube 1, one side of which is attached to the lower iron plate, and the other side is in the shape of a circular arc. The rotation stop device 10 is processed with a rotation stop arc-shaped groove 16, the circular arc angle of which is matched with the sliding sleeve 6. After the screw passing through the rotation stop arc-shaped groove 16 is fastened, the sliding sleeve 6 stops rotating.

[0023] In the preferred embodiment, as shown in Figure 4 The pile holding pawl 7 includes connecting rods and pawl parts. The rods are inserted into the square hole of the sliding sleeve 6. The pawl parts are provided with a through hole on the pawl edge close to the sliding sleeve 6, and a bearing 19 is installed in the through hole. The swing arm sleeve 18 is fixed on the pawl part by the screw 17 and the matching nut passing through the bearing 19. The swing arm 8 is in the shape of a 7, which is welded on the swing arm sleeve 18. When the pile needs to be held, the swing arm 8 is turned to the F opening state. After the F holds the cement pile, the swing arm 8 is rotated to the F closed state, and the swing arm 8 is locked by the check device 9 and cannot be reversed.

[0024] In the preferred embodiment, as shown in Figure 5As shown, the check device 9 includes a check seat 21 and a check tongue 20, the check tongue 20 is provided with an axle hole at one end, and is fixed on the check seat 21 through a rotating shaft on the axle hole, and the rotating shaft is provided with a torsion spring 22. Figure 5 The left side figure is the structure of the pile holding claw 7 in the opening state, the check seat 21 is fixed on the side of the pile holding claw 7, the check tongue 20 is provided with a small hole at one end, and the small hole is penetrated into the rotating shaft on the check seat 21, the check tongue 20 is in the standing state under the elastic action of the torsion spring 22, when the swing arm 8 moves from right to left, the right side of the check tongue 20 is compressed by the swing arm 8, the check tongue 20 rotates counterclockwise, like Figure 5 When the swing arm 8 is separated from the right side of the check tongue 20 (at this time, the right side becomes the upper side), the check tongue 20 cannot be compressed, and the check tongue 20 is popped up under the action of the torsion spring 22 until Figure 5 The right side figure is that the other side of the check tongue 20 is pressed against the swing arm 8, and the check tongue 20 no longer rotates, because one vertical side of the check tongue 20 is pressed against the swing arm 8, so that the swing arm 8 cannot rotate to the right, thereby realizing the one-way operation of the swing arm 8. The opening becomes a mouth-shaped, and the cement detection pile is held.
