[0002] With the continuous development of society and the continuous advancement of science and technology, the technologies related to construction are also constantly improving. In the installation of pressure-bearing and load-bearing structures such as steel arch gates in hydropower stations, in order to ensure the installation accuracy of the steel structure and to avoid the cross-operation between civil engineering and installation and the mutual influence, corresponding holes, holes or pits will be reserved at the steel structure installation position in the early civil construction to facilitate the later installation of the steel structure base. After the steel structure is installed and the accuracy meets the requirements and the acceptance is passed, the second phase of concrete pouring will be carried out, that is, the holes in the steel structure will be backfilled.

[0003] At present, when backfilling the reserved installation holes of civil engineering casting bodies, it is necessary to set up a chute to assist the concrete in entering the warehouse. Since the backfill position is located inside the structure and there are a large number of steel structures around it, the space limitation during construction is large, and the construction operation of setting up the chute is relatively difficult, which is not conducive to the backfill construction of the reserved installation holes of the civil engineering building. Utility Model Content

[0007] A bidirectional screw is rotatably installed on the support platform, and two moving blocks with a T-shaped cross section are threadedly connected to the bidirectional screw, one of the moving blocks is fixedly connected to a bending rod, and both ends of each moving block are fixedly connected to an extrusion block, and each extrusion block is provided with a limiting opening for connecting the support rod. Two support seats are fixedly connected to the support platform, and a blocking frame is slidably connected to the two support seats. A T-shaped rod is rotatably connected between the two support seats, and the T-shaped rod is fixedly connected to the rotating rod.

[0008] Preferably, the blocking frame includes an integrally formed blocking plate and two sliding rods, the two sliding rods are slidably connected to the two supporting seats respectively, and the cross section of the blocking plate is arranged in a U-shape.

[0009] Preferably, a torsion spring is sleeved on the T-shaped rod, one end of the torsion spring is fixedly connected to the T-shaped rod, and the other end of the torsion spring is fixedly connected to the support seat.

[0010] Preferably, each of the support rods is sleeved with a first spring, one end of the first spring is fixedly connected to the support rod, and the other end of the first spring is fixedly connected to the support platform.

[0012] Preferably, a slide groove is provided on the support platform, and the lower end of each of the moving blocks is slidably connected to the slide groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] After each support rod moves downward, each pulley will be separated from the ground, thereby preventing the pulley from rolling and causing the support platform to move at will, so as to improve the stability of the support platform during construction. After the sealing plate contacts the steel structure and seals the installation hole, mortar can be injected into the interior of the installation hole through the pouring pipe. The sealing plate can prevent the mortar from seeping out of the installation hole, so that the mortar can fully fill the installation hole. There is no need to set up a chute, the operation is relatively convenient, and the narrow space is also convenient for filling, which is conducive to the backfill construction of the reserved installation hole of the earth building.

A bidirectional screw rod 14 is rotatably installed on the support platform 1, and two moving blocks 2 with a T-shaped cross section are threadedly connected on the bidirectional screw rod 14, one of the moving blocks 2 is fixedly connected to a bending rod 8, and both ends of each moving block 2 are fixedly connected to an extrusion block 13, and each extrusion block 13 is provided with a limiting opening for connecting the support rod 4, two support seats 9 are fixedly connected to the support platform 1, and a blocking frame is slidably connected to the two support seats 9. A T-shaped rod 10 is rotatably connected between the two support seats 9, and a rotating rod 12 is fixedly connected to the T-shaped rod 10.

[0023] The blocking frame includes an integrally formed blocking plate 11 and two sliding rods 17. The upper ends of the two sliding rods 17 are fixedly connected to the lower surface of the blocking plate 11. The two sliding rods 17 are respectively slidably connected to the two support seats 9. The cross-section of the blocking plate 11 is arranged in a U-shape. During the upward rotation of the rotating rod 12, it will move against the lower surface of the blocking plate 11, thereby causing the blocking plate 11 to move upward. Each sliding rod 17 extends to the outside of the support seat 9 at the same time until the blocking plate 11 contacts the steel structure and the mounting hole is sealed.

[0024] A torsion spring 16 is sleeved on the T-shaped rod 10, one end of the torsion spring 16 is fixedly connected to the T-shaped rod 10, and the other end of the torsion spring 16 is fixedly connected to the support seat 9. During the movement of the bending rod 8, it will move against the surface of the T-shaped rod 10, so that the T-shaped rod 10 and the support seat 9 rotate relative to each other, and the torsion spring 16 is deformed. A first spring 5 is sleeved on each support rod 4, one end of the first spring 5 is fixedly connected to the support rod 4, and the other end of the first spring 5 is fixedly connected to the support platform 1. As each extrusion block 13 moves with the moving block 2, the oblique inner wall of each limit opening will move against the upper end of the corresponding support rod 4, thereby causing each support rod 4 to move downward at the same time, and the first spring 5 is deformed.

Then, the servo motor is powered on and drives the bidirectional screw 14 to rotate. The two moving blocks 2 move along the bidirectional screw 14 at the same time, and the distance between the two moving blocks 2 is reduced. As each extrusion block 13 moves with the moving block 2, the inclined inner wall of each limit opening will move against the upper end of the corresponding support rod 4, thereby causing each support rod 4 to move downward at the same time. The first spring 5 is deformed, and after each support rod 4 moves downward, each pulley 7 will be separated from the ground, thereby preventing the pulley 7 from rolling and driving the support platform 1 to move at will.
