Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy engineering, and particularly relates to an asymmetric pull rod structure for a ship lift lock gate. BACKGROUND

[0002] The ship lift is a kind of navigation building for ship to pass through the concentrated water level difference on the navigation channel. The ship lift is composed of upper and lower lock heads, a ship chamber (a ship car), a supporting and guiding structure and a driving device.

[0003] The design of the ship lift lock gate has a large gate opening width and a large supporting width, and the self weight of the gate is large, so that a double-point hydraulic hoist is needed for operation. The traditional gate pull rod structure is designed symmetrically, and four locking devices (such as the double-point pull rod gate provided in CN106638493A) are needed.

[0004] However, for the ship lift project with limited space, the civil structure cannot provide effective bilateral support, and can only provide unilateral support outside the gate slot. If the traditional symmetric pull rod design is continued, the following problems will exist:

[0005] (1) The unilateral support of the conventional pull rod structure will generate a large overturning moment compared with the bilateral support, which will affect the safety and stability of the equipment;

[0006] (2) In order to cope with the overturning moment, the strength of the pull rod and the locking device needs to be increased from the structure, which will greatly increase the size of the pull rod and the locking device;

[0007] (3) The large-sized pull rod and the locking device are not conducive to the compact arrangement of the equipment, and increase the complexity and installation cost of the overall structure.

[0008] Therefore, when the traditional symmetric pull rod design is applied to the ship lift project with limited space, the structural design of the pull rod and the locking device is very difficult, and it is difficult to realize a safe and reliable gate pull rod structure. SUMMARY

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0036] The spacing between the upper part of Z-shaped outer flange plate 1 and lug plate 3 is greater than the spacing between the lower part of Z-shaped outer flange plate 1 and the lower part of Z-shaped inner flange plate 2. According to this size setting, the connection between the two pull rods is facilitated; when it is required to connect the two pull rods up and down, the end part of the Z-shaped outer flange plate 1 and the lug plate 3 of the lower pull rod can be sleeved on the end part of the Z-shaped outer flange plate 1 and the Z-shaped inner flange plate 2 of the upper pull rod, so that the assembly holes are aligned, and the pull rod connecting shaft 15 is facilitated to be installed.

[0037] The range surrounded by Z-shaped outer flange plate 1, Z-shaped inner flange plate 2, lug plate 3 and locking plate 6 is provided with a special-shaped web 5, the top edge of the special-shaped web 5 is located between Z-shaped outer flange plate 1 and lug plate 3, the bottom edge of the special-shaped web 5 is located between Z-shaped outer flange plate 1 and Z-shaped inner flange plate 2 and is arranged below the two angles, the left side of the special-shaped web 5 is connected with the inner wall of Z-shaped outer flange plate 1, and the right side of the special-shaped web 5 is connected with the inner wall of Z-shaped inner flange plate 2, the top surface of locking plate 6 and the inner wall of lug plate 3 from bottom to top respectively. The special-shaped web 5 serves to improve the structural strength of the pull rod web.

[0038] The connecting position of the locking plate 6 and the Z-shaped inner flange plate 2 is arranged at a position deviated from the top end of the Z-shaped inner flange plate 2; the special-shaped web plate 5 is provided with a triangular notch 11 at the top end of the Z-shaped inner flange plate 2. Because the locking plate 6 is subjected to a vertical upward force, it needs to be provided with double-sided welds when connected, so that the structure is safer and more reliable than that with single-sided welds; therefore, the connecting position of the locking plate 6 and the Z-shaped inner flange plate 2 is arranged at a position deviated from the top end of the Z-shaped inner flange plate 2, a weld processing position is left, and the triangular notch 11 is arranged on the special-shaped web plate 5, so as to avoid interference with the fillet weld.

[0039] The special-shaped web plate 5 is connected with a plurality of web plate reinforcing plates 8, and the two sides of the web plate reinforcing plate 8 are connected with the inner wall of the Z-shaped outer flange plate 1 and the inner wall of the Z-shaped inner flange plate 2, respectively. By arranging the web plate reinforcing plate 8, the strength and stability of the pull rod at the special-shaped web plate 5 are improved.

[0040] The two sides of the L-shaped corner position composed of the Z-shaped outer flange plate 1, the Z-shaped inner flange plate 2, the lug plate 3 and the locking plate 6 are provided with locking plate lateral reinforcing plates 9, and the inner side walls of the locking plate lateral reinforcing plates 9 are connected with the side edges of the Z-shaped outer flange plate 1, the Z-shaped inner flange plate 2, the lug plate 3 and the locking plate 6. By arranging the locking plate lateral reinforcing plate 9, the problem of local stress concentration at the L-shaped corner position is overcome, the stress uniformity of the structure is improved, and the local strength of the pull rod is enhanced.

[0041] The Z-shaped outer flange plate 1, the Z-shaped inner flange plate 2 and the lug plate 3 are provided with reinforcing plates on both sides of the assembly hole arrangement position. The assembly hole is preferably in the shape of a pear-shaped hole, which is used for the connection between the pull rods, the pull rods and the ship lift lock gate, and the pull rods and the hoisting equipment (hoist). When connected, the pull rod connecting shaft 15 structure can be used; the reinforcing plate has the effect of improving the strength of the connection structure. The structure of connecting two sections of pull rods by using the pull rod connecting shaft 15 is shown in Figure 6 .

[0042] It should be further pointed out that the above-mentioned components of the present pull rod are preferably made of steel plates, and the connection mode adopts welding.

[0043] The above-mentioned asymmetric pull rod structure for the ship lift lock gate is applied to obtain a ship lift lock gate with an asymmetric pull rod structure for the ship lift lock gate, which has a structure similar to a conventional gate and includes a gate slot 12, a gate 13 and a hoist 14. The structure is shown in Figures 7-8As shown, the gate 13 is characterized in that the left and right parts of the top of the gate 13 are connected with the hoist 14 through the pull rod assembly respectively; the pull rod assembly is connected by using a plurality of the asymmetric pull rod structures for the ship lift gate head gate described above, and the connection mode of the adjacent asymmetric pull rod structures for the ship lift gate head gate is that the lower part of the Z-shaped outer flange plate 1 and the lower part of the Z-shaped inner flange plate 2 of the asymmetric pull rod structure for the ship lift gate head gate located at the upper part are arranged between the upper part of the Z-shaped outer flange plate 1 and the lug plate 3 of the asymmetric pull rod structure for the ship lift gate head gate located at the lower part, so that the four assembly holes are aligned and the pull rod connecting shaft 15 is arranged to pass through and connect the adjacent two asymmetric pull rod structures for the ship lift gate head gate.

[0044] The above embodiment structure is applied, and the application background is that in the Silin ship lift project, because the civil structure cannot provide bilateral support, only one side support outside the gate slot can be provided, so the conventional symmetric pull rod design cannot be used (if the conventional symmetric pull rod is insisted to be used, the support structure on one side is simply strengthened, because the metal structure is heavy in weight, and the distance between the support center line and the pull rod structure center line (the gravity center line / the lug center line is coincident) is large, a large overturning moment is generated, the size of the pull rod and the locking device needs to be greatly increased; at the same time, because the installation position space of the locking device is limited, if the method of simply increasing the size of the conventional pull rod structure is used, the design difficulty of the ship lift civil structure is greatly increased, so the pull rod and the locking device are not suitable for the conventional symmetric structure design).

[0045] And the embodiment structure of the present application is applied in the Silin ship lift project, because the locking structure is arranged on one side, the overturning moment is effectively reduced, the stability of the overall structure is improved, and the problem that the conventional symmetric structure pull rod is prone to overturning is solved; and through the asymmetric structure, the overall structure is more simple and compact, the installation space is reduced, the compact arrangement of the device is realized, the complexity of the overall structure is reduced, and the implementation effect is good.
