Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy aqueduct construction, and particularly to a middle support leg assembly and a flume making machine. Background Art

[0002] A flume making machine is a construction equipment required in the manufacture of flumes. The flume making machine is installed on each capping beam of a channel to process a flume between each capping beam. The flume making machine includes a mid-span connecting beam and support legs and a formwork trough frame that displace along the mid-span connecting beam. When the support legs move to the position of the capping beam, they need to be connected to the capping beam to form a stable structure to ensure effective connection and safety during the pouring construction of the flume.

[0003] The connection between the existing support legs of the flume making machine and the capping beam adopts the structure of an ear plate locking anchor buckle. Due to the limited shear load of the ear plate, the ear plate is prone to breakage or dislocation when the support legs apply pressure downward on the capping beam. When pouring concrete for the flume, there is a risk of collapse due to the increased load. This structure with insufficient connection stability requires adaptation to a continuous transverse movement machine frame, which will slow down the working progress of the flume making machine and also requires multiple repairs for adjustment. Summary of the Invention

[0004] The purpose of the present invention is to provide a middle support leg assembly and a flume making machine that can make the flume making machine firmly built and have no risk of collapse when pouring concrete for the flume.

[0005] The technical solution of the present invention is: a middle support leg assembly, including a middle support leg and an anchoring seat connected to the lower end of the middle support leg. The anchoring seat includes a beam body, a clamping jaw, and a locking member. The beam body is provided with a first hinge hole, a second hinge hole located above the first hinge hole, and a third hinge hole located horizontally outside the first hinge hole: one end of the clamping jaw is provided with a fourth hinge hole and a fifth hinge hole, and the other end of the clamping jaw is connected to the locking member. The fourth hinge hole is coaxially arranged with the first hinge hole, so that the clamping jaw rotates to form a first position or a second position. In the first position, the fifth hinge hole is aligned with the second hinge hole and is detachably connected by a pin. In the second position, the fifth hinge hole is aligned with the third hinge hole and is detachably connected by a pin;
