[0003] In this regard, according to the retrieval report of the novelty search agency, the patent with publication number CN212452312U discloses an assembled construction support for bridge tower cross beams. At least a pair of mounting holes are transversely and oppositely arranged on the two side tower bodies of the bridge tower, including: at least one main strut, and each main strut is clamped between a pair of the mounting holes; an integral support frame, which is installed between the bridge tower cross beam of the bridge tower and the main strut, and the bottom of the integral support frame is detachably connected to the main strut; and at least a pair of corbels, which are respectively clamped between a pair of the mounting holes, and the corbels are connected to the main strut through diagonal support frames. A series of installation operations are carried out by using the mounting holes on the tower body, relying on the force balance of the tower body, the production, installation and construction are simple, fast, energy-saving and environment-friendly, the cost is saved, the construction progress is accelerated, the construction period is shortened, and it is convenient for turnover use.

[0004] For the assembled construction support for bridge tower cross beams disclosed above, by setting two pairs of mounting holes on the bridge tower and then installing and fixing the whole support through four tie rods in cooperation with external nut pads and other structures, the installation and support by using the tower body are realized, avoiding the problems of high height and large material consumption of the floor support.

The wireless remote control switch is matched with an external remote controller. The second piston 10 and the multi-stage electric telescopic rod 11 are arranged to cooperate. By using the multi-stage electric telescopic rod 11 to drive the second piston 10 to move upward or downward, the hydraulic oil in the upper part of the oil storage cylinder 9 can be pushed upward or the hydraulic oil in the lower part can be pushed downward respectively.

[0031] Further, the first oil passage assembly includes a return pipe 14 fixedly connected between the two main support rods 1. The V-shaped connection seat 2 is located inside the corresponding return pipe 14. A first explosion-proof hose 13 is fixedly connected and communicated between the side of the return pipe 14 close to the oil storage cylinder 9 and the top outside the oil storage cylinder 9.

The oil passage pipe 15 is located on the side of the corresponding piston 6 close to the oil storage cylinder 9. The first explosion-proof hose 13, the return pipe 14 and the oil passage pipe 15 are arranged to cooperate. When the hydraulic oil in the upper part of the oil storage cylinder 9 is pushed upward, it will sequentially pass through the two first explosion-proof hoses 13, the two return pipes 14 and the four oil passage pipes 15 and be split into the four sliding grooves 5, and the four first pistons 6 are driven to be extruded outward.

[0032] Further, the second oil passage assembly includes a communicating pipe 12 embedded and fixed on the adjacent sides of the two main support rods 1. The top and bottom ends of the communicating pipe 12 are respectively communicated with the corresponding sliding grooves 5. The communicating pipe 12 is located on the side of the corresponding piston 6 away from the oil storage cylinder 9. A second explosion-proof hose 16 is fixedly connected and communicated between the side of the communicating pipe 12 close to the oil storage cylinder 9 and the bottom outside the oil storage cylinder 9.

[0033] The method of using this embodiment is as follows: two V-shaped connecting seats 2 and two diagonal braces 3 are used to strengthen the connection between the two main braces 1 to form an integral body. At this time, the clamping brace 7 and the corresponding mounting clamp hole 101 are in a clamping state and in an installed state. At this time, the four clamping brace rods 7 are used to support the two supports 4, and the two supports 4 are used to support the two main braces 1. The upper main brace 1 is used to temporarily support the overall brace 200, and the overall brace 200 supports the bridge tower beam of the bridge tower 100;

[0034] When the assembled construction support body is dismantled after subsequent construction, the multi-stage electric telescopic rod 11 is started in reverse to drive the second piston 10 to squeeze and push the hydraulic oil in the lower part of the oil storage cylinder 9 downward. At this time, the hydraulic oil in the lower part of the oil storage cylinder 9 is diverted to the two connecting pipes 12 through the two second explosion-proof hoses 16, and then diverted to the four slide grooves 5 through the two connecting pipes 12, and is located on the side of the first piston 6 away from the oil storage cylinder 9. As the hydraulic oil enters, the hydraulic oil in the four slide grooves 5 squeezes and drives the four first pistons 6 to slide inward synchronously in the four slide grooves 5. At this time, the four first pistons 6 drive the four card support rods 7 to move inward, so that the four card support rods 7 are synchronously moved out of the four mounting card holes 101, and the card support connection state is released. The assembled construction support body can be moved down by external lifting equipment, so that it is convenient to unlock and disassemble the four points quickly and synchronously without tools after use, and there is no need to use special tools to unlock and disassemble one by one.

[0035] During installation, the personnel starts the multi-stage electric telescopic rod 11 in the positive direction to drive the second piston 10 to move upward, so that it can draw back the hydraulic oil in the lower part of the oil reservoir 9, so as to draw back the hydraulic oil in the direction of the first piston 6 away from the oil reservoir 9. When the second piston 10 moves upward, it also squeezes and pushes the hydraulic oil in the upper part of the oil reservoir 9. At this time, the upper hydraulic oil is divided into four chutes 5 through two first explosion-proof hoses 13, two round-shaped pipes 14 and four oil pipes 15 in turn, and is located on the side of the first piston 6 close to the oil reservoir 9. At this time, as the hydraulic oil enters, the four first The piston 6 slides outward in the four slide grooves 5. At this time, the four first pistons 6 drive the four support rods 7 to move outward synchronously and insert into the four mounting holes 101 for supporting work, so that the four support rods 7 can be driven out synchronously and quickly to insert into the four mounting holes 101 during use, so that tool-free synchronous and rapid four-point support connection can be achieved during use, and there is no need to use special tools to perform installation work at each position. Combined with the above-mentioned synchronous four-point unlocking and disassembly, it is convenient to quickly and integratedly perform the connection and unlocking and disassembly work at four positions, thereby improving work efficiency and operating convenience.
