Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pumping station technology and relates to a self-processing wooden template device for the curved section of the flow channel of a hydraulic pumping station. Background Technology

[0002] In the construction of water conservancy and hydropower projects, the inlet and outlet channels of hydraulic pumping stations and the tailrace pipes of hydropower stations are generally designed with irregular curved surface structures. The fabrication and installation of such variable cross-section irregular curved surface formwork is a challenging construction task. Hydraulic pumping stations require the construction of inlet and outlet channel formwork, which is constructed using wooden formwork and then reinforced with concrete. The use of prefabricated wooden formwork or on-site support is employed; the wooden formwork is removable and cost-effective.

[0003] The equipment for processing wooden formwork for the inlet and outlet channels of hydraulic pumping stations is large in size and heavy in weight, with complex shapes and internal support structures. It has disadvantages such as long production time, low precision, poor overall stability, and difficulty in ensuring smooth channel lines, posing certain difficulties in manufacturing, processing, and on-site support. Chinese patent "A Wooden Formwork for the Outlet Channel of a Vertical Shaft Axial Flow Pump" (Application Date: 2021.05.19; Application No.: CN202121078020.2; Publication Date: CN217735755U; Publication No.: 2022.11.04) discloses a wooden formwork for the outlet channel of a vertical shaft axial flow pump, including a formwork frame, with assembled formwork set outside the formwork frame. The formwork frame includes several irregular cross-section formwork frames, which are set at certain intervals and connected and fixed by longitudinal connecting rods. However, the formwork frame is a square structure of different sizes, formed by grinding the edges. When processing the formwork on-site, it is difficult to grind the edges quickly and accurately, and simple manual grinding cannot guarantee the accuracy for subsequent use. Utility Model Content

[0026] Based on embodiment 2, the fixing frame 5 adopts a right-angle steel structure. The right-angle steel structure includes two mutually perpendicular side plates.

[0027] like Figure 3As shown, an electric push rod 62 is fixedly installed at the end of the slide plate 61. The output rod of the electric push rod 62 is perpendicular to the extension direction of the slide plate 61. The end of the output rod of the electric push rod 62 is connected to the mounting plate 63. The mounting plate 63 is horizontally set. A motor 67 is fixedly installed on the mounting plate 63. The output shaft of the motor 67 passes through the mounting plate 63 and is vertically connected to the crank 68. A push rod 69 is fixedly installed at the bottom of the other end of the crank 68. A through hole is opened at the center of the mounting plate 63. A rotating shaft 64 is rotatably engaged in the through hole.

[0029] The working principle of this utility model of a self-processing wooden template device for the curved section of a hydraulic pumping station flow channel is as follows: After the template frame 3 is clamped by the positioning mechanism 4, the fixing frame 5 and the sliding plate 61 move along the diagonal direction of the template frame 3. The sliding plate 61 is adjusted by the screw so that the rotating shaft 64 coincides with the axis of the grinding curve.

The radius of the grinding curve is adjusted by adjusting the position of the adjusting rod 610 and locking it with the locking bolt. The motor 611 drives the grinding rod 612 to rotate, and the electric push rod 62 moves the mounting plate 63 down, so that the grinding rod 612 can accurately grind the edges and corners of the template frame 3. This solves the problem that existing template frames are formed by grinding the edges and corners, and it is difficult to grind the edges quickly and accurately when processing templates.

[0030] The working process of this utility model's self-processing wooden template device for the curved section of a hydraulic pumping station flow channel is as follows: After the template frame 3 is placed on the placement platform 2, the worm gear 45 is rotated. The worm gear 45 drives the turntable 41 to rotate through the toroidal worm wheel 44. The turntable 41 simultaneously drives the four clamping plates 42 to move towards the axis of the placement platform 2 through the planar thread 43, thereby self-centering and clamping the template frame 3 so that the square center of the template frame 3 coincides with the axis of the placement platform 2. After the template frame 3 is clamped, the fixing frame 5 and the sliding plate 61 move along the diagonal direction of the template frame 3. The sliding plate 61 is adjusted by the screw so that the rotation... Shaft 64 coincides with the grinding curve axis. Motor 67 drives crank 68 to rotate, and push rod 69 drives swing frame 65 to swing back and forth along shaft 64 through waist groove 66. The swing angle is 90°. By adjusting the position of adjusting rod 610 and locking it with locking bolt, the radius of grinding curve can be adjusted. Motor 611 drives grinding rod 612 to rotate, and electric push rod 62 drives mounting plate 63 to move down, so that grinding rod 612 can accurately grind the edges and corners of template frame 3, conforming to the flow channel curve section template curve, and meeting the self-processing of template frames of different sizes of wooden templates.
