Description

Technical Field

[0001] The utility model relates to the technical field of construction of a ship lock water delivery gallery, in particular to a fast shaping device for a steel face of a ship lock water delivery gallery. Background Art

[0002] The most commonly used modern navigation structure is the ship lock, which is a box-shaped structure consisting of upstream and downstream pilot channels and upstream and downstream gates connected to the lock chamber. The lock chamber is a box-shaped chamber for mooring ships. The water level in the lock chamber is adjusted by filling or draining water in the chamber, so that the ship can be vertically raised and lowered between the upstream and downstream water levels, thereby passing through the concentrated water level difference of the channel. When the ship travels from downstream to upstream, the water level in the chamber drops to the same level as the downstream water level, and then the gate of the downstream gate is opened, the ship enters the lock chamber, the gate is closed, and water is filled. After the water level rises to the same level as the upstream water level, the gate of the upstream gate is opened, and the ship can exit the lock through the upstream pilot channel and sail upstream. When the ship travels from upstream to downstream, the operation procedure for passing the lock is the opposite. The filling and filling or draining of the lock chamber needs to be completed with the help of the water transfer corridor. The filling and draining time of the water transfer corridor should be as short as possible and meet the requirements for the stable mooring of ships passing through the lock. The filling and draining time of the ship lock is generally 10 to 15 minutes. The stability of the mooring of ships passing through the lock is usually measured by the force of the water flow on the ships passing through the lock during the filling and discharge of the lock chamber, that is, the tension on the mooring ropes of the ships passing through the lock. The allowable value is generally 1 / 600 to 1 / 2000 of the ship's displacement (in tons). There are two basic forms of water delivery corridors: ① Centralized water delivery system. The filling and discharge of the lock chamber are concentrated at the lock head through the water delivery corridors located in the upper and lower lock heads, also known as the head water delivery system; ② Decentralized water delivery system. The filling and discharge of the lock chamber are carried out by the water delivery corridor through the outlets distributed along the length of the lock chamber on the lock chamber floor or in the lock wall. Water delivery valves are installed on the water delivery corridor. During the process of water inlet and outlet, the water delivery valve on the water delivery corridor is opened, and the water flow has a greater impact on the water delivery corridor, which is destructive to a certain extent. Especially when the high water level valve is just opened, vortices are easily formed at the sharp turns of the water flow in the water delivery corridor, causing cavitation and water hammer. This cavitation and water hammer have a strong vibration effect on the structures in the water delivery corridor. If cracks appear in the corridor, the internal concrete density is insufficient, and there are quality problems such as misalignment and leakage at the joint line between the plane and the curved surface of the water delivery corridor, cavitation and water hammer will have a destructive effect on the defective parts of the concrete surface. In order to reduce the damage caused by cavitation and water hammer caused by vortices formed at the sharp turns of the water flow in the lock water delivery corridor to the defective parts of the concrete surface, steel protective surfaces are added at the sharp turns of the water flow in the lock water delivery corridor to protect the lock water delivery corridor and reduce the destructive effect of cavitation and water hammer caused by the turbulent water flow on the structures of the water delivery corridor. These steel face guards of water conveyance corridors should be closely attached to the surface of the streamlined diversion piers in the water conveyance corridors. They are complex and asymmetric steel structure components. During the manufacturing process, due to the complex structure and asymmetric welding construction, thermal stress deformation is very easy to occur, and the deformation can easily exceed the requirements of the specifications.

[0003] Chinese patent 2023102944045 discloses the "Standardized System for the First Section of the Ship Lock Inlet Gate", with the publication number CN116335101A. The system includes an inlet section gate wall and a gate head structure, wherein the inlet section gate wall includes a maintenance gate slot and a water delivery corridor. The entrance of the water delivery corridor is set on the gate wall on both sides of the water inlet section, and a trash rack slot is provided. The water delivery corridor turns inside the gate wall and extends downstream along the length of the lock chamber. There are many sharp turns in the entire water delivery corridor, and steel protective surfaces need to be added.

[0004] Another Chinese patent 2023221041133 discloses "A high-precision correction support clamping structure for steel plates", with the announcement number CN220635873U. The clamping structure includes two parallel side plates, and a plurality of support rollers are rotatably connected at equal intervals between the two side plates at the lower position, and two legs are symmetrically fixed at both ends of the two side plates. It also includes two clamping propulsion mechanisms, and the two clamping propulsion mechanisms are respectively arranged on the outer sides of the two side plates. The clamping structure supports the lower side of the steel plate through a plurality of support rollers, and at the same time, the clamping propulsion mechanism can press the upper surface of the steel plate, and at the same time, apply thrust to the steel plate to push the steel plate to move, thereby improving the correction efficiency and correction effect of the steel plate. However, this clamping structure can only correct steel plates with regular shapes, and is powerless for the steel face of the asymmetric and complex structure of the lock water delivery gallery.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, the utility model of a rapid shaping device for the steel face of a water delivery gallery of a ship lock comprises an adjusting rod 2 and a clamping plate assembly connected to both ends of the adjusting rod 2, the clamping plate assembly is used to be connected to the edge of the steel face, the clamping plate assembly comprises a U-shaped groove 1, and a pin plate 12 fixedly connected to the outer wall of the U-shaped groove 1, the width of the U-shaped groove 1 is adapted to the thickness of the steel face 4, so that it can just fit into the edge of the upper chamfer 41 or the lower chamfer 42 of the steel face 4. The end of the adjusting rod 2 is provided with a pin 13 mounted on the pin plate 12, the pin plate 12 can be a shaft seat with the pin 13 installed, or can be a hanging ear with the pin 13 installed, and the pin 13 can be rotatably mounted on the pin plate 12. The upper chamfer 41 and the lower chamfer 42 of the steel face of the water delivery gallery of the ship lock are inclined toward the same side. The thermal stress deformation caused by the welding construction usually makes the distance between the upper chamfer 41 and the lower chamfer 42 greater than the deformation required by the specification. When in use, the clamping plate assemblies at both ends of the adjusting rod 2 are respectively clamped on the edge of the upper chamfer 41 and the edge of the lower chamfer 42 of the steel face 4. The distance between the upper chamfer 41 and the lower chamfer 42 can be reduced by contracting the adjusting rod 2 to meet the deformation required by the specification. When the length of the steel face is large, the requirements for the shape and deformation of the upper chamfer 41 and the lower chamfer 42 at different positions on the same steel face are not the same. At this time, accurate shaping of different parts can be achieved by setting such a plurality of rapid shaping devices in parallel.

[0024] like Figure 2 , Figure 3As shown, as an embodiment of the utility model, the adjusting rod 2 includes a rod body and an O-ring 21 connected to one end of the rod body by threading, and the other end of the O-ring 21 is connected to a screw 22 by reverse threading, that is, the threads at both ends of the same O-ring 21 have opposite directions of rotation. The end of the screw 22 is fixedly connected to a pin 13 installed on the pin plate 12, and the pin 13 is perpendicular to the axis of the screw 22, and the two are connected in a T-shape. The O-ring 21 is a circular ring body or a long strip ring structure, and the ring walls at both ends thereof are provided with coaxially arranged threaded holes, but the threads in the threaded holes have opposite directions of rotation. One end of the O-ring 21 is connected to the screw 22 and the other end is connected to the rod body. When the O-ring 21 is rotated with the axis of the rod body as the center, the screw 22 and the rod body move toward each other or in the opposite direction, changing the overall length of the adjusting rod 2, and applying tension to the upper chamfer 41 and the lower chamfer 42 of the steel face of the lock water delivery gallery.

[0025] In addition, as a further improvement of the present invention, a top screw 11 is threadedly connected to the side wall of the U-shaped groove 1. The top screw 11 penetrates the side wall of the U-shaped groove 1 and its front end is pressed on the upper chamfer 41 or the lower chamfer 42 to fix the U-shaped groove 1 on the upper chamfer 41 or the lower chamfer 42.

One end of the rod body connected to the O-ring 21 is a smooth rod 23, and the smooth rod 23 is inserted through the ring wall of one end of the O-ring 21. The end of the smooth rod is provided with an end cap 24 to prevent the smooth rod from falling off the O-ring 21. When the O-ring 21 is rotated, the smooth rod and the O-ring 21 rotate freely, and the screw 22 at the other end of the O-ring 21 moves axially with the rotation of the O-ring 21.
