[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a construction platform for a tailwater gate pier of a power plant building.

[0027] The utility model provides Figure 1-4 A construction platform for the tailwater pier of a power plant shown in the figure comprises a lower platform 1 and an upper platform 2, a plurality of symmetrically arranged hydraulic lifting columns 3 are fixedly arranged between the lower platform 1 and the upper platform 2, a protective frame 4 is fixedly arranged on the top of the upper platform 2, movable grooves are provided on both sides of the bottom of the inner wall of the protective frame 4, and extension frames 5 are provided inside the two movable grooves through a transverse moving mechanism, and side plates 7 are fixedly arranged on both sides of the lower end of the extension frame 5 through a plurality of connecting rods 6, and placement grooves 9 are provided on both sides of the protective frame 4 to match the side plates 7, and the transverse moving mechanism comprises a screw rod 10, which is rotatably arranged between the groove and the movable groove, and a slider 11 is fixedly arranged on the rod wall of the screw rod 10, and the slider 11 is slidably arranged in the movable groove and fixedly connected to the bottom of the extension frame 5, and two symmetrically arranged slide grooves are provided on both sides of the inner wall of the protective frame 4, and a pulley 23 is slidably arranged in the slide groove, and the pulley 23 is fixedly connected to the lower end of the side wall of the extension frame 5, a groove is provided at the middle end of the bottom of the inner wall of the protective frame 4, and a U-shaped plate 8 is fixedly arranged at the upper end of the inner wall of the protective frame 4.

[0028] Before the construction of the tailwater pier, the lower platform 1 is moved to the construction area, and the upper platform 2 and the protective frame 4 are supported and pushed up by a plurality of hydraulic lifting columns 3. When the protective frame 4 is moved to the construction height, the pier can be constructed. When it is necessary to assist in different lateral construction areas, the screw rod 10 at the corresponding position can be selected according to the use area, and the screw rod 10 is driven to rotate to drive the slider 11 to drive the extension frame 5 to move laterally. During this process, the side plate 7 slides in the placement groove 9. At the same time, with the cooperation of the pulley 23 and the slide groove, the extension frame 5 moves laterally and the use area of ​​the construction platform is lengthened, thereby improving the versatility of the construction platform.

[0029] In order to be able to drive the two side extension frames 5 separately according to different construction areas, such as Figure 2-3 As shown, a mobile driving mechanism for separate driving is provided between the U-shaped plate 8 and the groove, and the mobile driving mechanism includes a vertical rod 12, and a mobile plate 13 is rotatably sleeved on the upper end of the vertical rod 12, and positioning rods 14 are slidably penetrated at both ends of the inner part of the mobile plate 13, and the rod wall of the positioning rod 14 is sleeved with a first spring 15, and the two ends of the first spring 15 are respectively fixedly connected to the positioning rod 14 and the mobile plate 13, and two positioning grooves for matching the positioning rod 14 are provided on the rear side of the inner wall of the U-shaped plate 8, and a pull rod 16 is fixedly provided at the end of the positioning rod 14, and a rotating block 17 is fixedly provided on the top of the vertical rod 12, and a bevel gear 18 is fixedly provided at one end of the vertical rod 12 and the screw rod 10.

[0030] After the extension frame 5 to be adjusted is selected, the upper pull rod 16 can be pulled to allow the positioning rod 14 to stretch the first spring 15 while moving away from the positioning groove on one side. The movable plate 13 and the vertical rod 12 are then moved laterally, and the pull rod 16 is released after moving to the target position. The elastic force of the first spring 15 is restored to allow the positioning rod 14 to be inserted into the positioning groove, and the vertical rod 12 is preliminarily positioned. At this time, the two adjacent bevel gears 18 below are meshed. At this time, by rotating the vertical rod 12 and through the meshing of the two bevel gears 18, the two screw rods 19 can be driven separately.

[0031] In order to stably support the vertical rod 12 when the vertical rod 12 moves and rotates, Figure 2 As shown, a support ring 19 is fixedly provided at the lower end of the inner wall of the protective frame 4, the vertical rod 12 is arranged in the support ring 19, and a ring 22 is rotatably sleeved at the lower end, guide rods 20 are fixedly provided on both sides of the ring 22, and guide grooves are opened on both sides of the inner wall of the support ring 19, and the end of the guide rod 20 is slidably provided in the guide groove and a second spring 21 is fixed between the inner wall of the guide groove.

[0032] During the movement of the vertical rod 12, the outer wall of the collar 22 contacts and cooperates with the inner wall of the support ring 19. Through the sliding cooperation of the guide rod 22 and the guide groove, and under the rotation support of the second spring 21 and the collar 22, the vertical rod 12 can be guaranteed to perform stable lateral movement and rotation, thereby improving the convenience of use of the construction platform. Two left and right second springs 21 are provided in the guide groove on one side, and the second spring 21 is arranged in the guide groove. At the same time, the two second springs 21 are fixed to the side walls of the guide rod 20, which can provide stable lateral support for the vertical rod 12 when the vertical rod 12 moves.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
