Description

Technical Field

[0001] This utility model relates to the field of hydraulic gate technology, and in particular to a hydraulic sealing gate. Background Technology

[0002] Existing hydraulic sealing gates suffer from poor sealing performance and large installation space requirements. Furthermore, existing hydraulic sealing gates have externally mounted hydraulic cylinders, causing the gate to extend out of the housing after opening, resulting in poor sealing performance. When closing the gate, there is no wedge-shaped top block, leading to insufficient compression of the sealing strip and poor sealing performance. The installation space required is one more gate travel position than that of the concealed type. Therefore, we propose a hydraulic sealing gate to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned shortcomings and to propose a hydraulic sealing gate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hydraulic sealing gate includes a gate housing, on which a hydraulic gate mechanism is provided. The hydraulic gate mechanism includes a hydraulic cylinder rotatably connected to the inner wall of one side of the gate housing. A piston rod is fixedly connected to the output shaft of the hydraulic cylinder, and one end of the piston rod is rotatably connected to a gate. The piston rod is located inside the gate.

[0006] As a preferred embodiment of this utility model, a left position switch and a right position switch are fixedly connected inside the gate housing, and both the left position switch and the right position switch are coordinated with the gate.

[0007] As a preferred embodiment of this utility model, the top of the gate housing is provided with an opening, and the gate is slidably fitted into the opening.

[0008] As a preferred embodiment of this utility model, a mounting bracket is fixedly connected inside the opening, and a sealing strip is fixedly connected to the bottom of the mounting bracket, with the sealing strip movably abutting against the top of the gate.

[0009] As a preferred embodiment of this utility model, the bottom of the mounting bracket is threaded with several screws, and an anti-slip pad is slidably fitted on the outside of the screws. The top of the sealing strip has multiple through holes, and the screws are slidably fitted in the corresponding through holes. The anti-slip pads are movably abutted between the sealing strip and the screws.

[0010] As a preferred embodiment of this utility model, a lower wedge-shaped top block is fixedly connected to the bottom inner wall and one side inner wall of the gate housing, and an upper wedge-shaped top block is fixedly connected to the bottom left side and right top side of the gate, and the upper wedge-shaped top block movably abuts against the inclined surface of the corresponding lower wedge-shaped top block.

[0011] As a preferred embodiment of this utility model, the gate housing is threaded with fixing screws on both the bottom inner wall and one side inner wall, and the two wedge-shaped top blocks are respectively fixedly connected to the bottom inner wall and one side inner wall of the gate housing by fixing screws.

[0012] In this utility model, a hydraulic sealing gate is provided with power to a hydraulic cylinder by a hydraulic station. The hydraulic cylinder drives the piston rod to extend, and the piston rod drives the gate to move to the left to block and close the opening. When the gate is closed to the left position switch, the left position switch sends a signal and the hydraulic oil supply stops. When the gate is opened to the right position switch, the right position switch (also known as a limit switch) sends a signal and the hydraulic oil supply stops, thereby achieving the control of the opening and closing of the gate.

[0013] In this utility model, the hydraulic sealing gate, when closed, will cause the upper wedge-shaped top block to move to the left and slide on the inclined surface of the lower wedge-shaped top block. Under the compression and lifting of the lower wedge-shaped top block, the compression of the sealing strip increases, thereby improving the sealing performance. The hydraulic cylinder is built into the structure, and the gate does not protrude from the gate housing when opened. The equipment has fewer opening positions, making the structure more compact and requiring less installation space.

[0014] This utility model has a reasonable structural design. The hydraulic cylinder is internally mounted, and the gate does not extend outside the gate housing after opening. The gate closing band has an upper wedge-shaped top block and a lower wedge-shaped top block. The sealing strip has a large compression capacity and good sealing performance. The equipment has fewer opening positions, a more compact structure, less installation space, and high reliability. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A hydraulic sealing gate includes a gate housing 1, on which a hydraulic gate mechanism is provided. The hydraulic gate mechanism includes a hydraulic cylinder 2 rotatably connected to the inner wall of one side of the gate housing 1. A piston rod 21 is fixedly connected to the output shaft of the hydraulic cylinder 2. One end of the piston rod 21 is rotatably connected to a gate 5. The piston rod 21 is located inside the gate 5. A left position switch 3 and a right position switch 4 are fixedly connected inside the gate housing 1. Both the left position switch 3 and the right position switch 4 cooperate with the gate 5.

[0023] The above scheme is adopted: the hydraulic station provides power to the hydraulic cylinder 2, the hydraulic cylinder 2 drives the piston rod 21 to extend, the piston rod 21 drives the gate 5 to move to the left to block and close the opening 13. When the gate 5 is closed to the position of the left position switch 3, the left position switch 3 sends a signal and the hydraulic oil supply stops; when the gate 5 is opened to the right position switch 4, the right position switch 4 (also known as the limit switch) sends a signal and the hydraulic oil supply stops, thereby achieving the control of the opening and closing of the gate 5.

[0024] As a further feature of this invention, the top of the gate housing 1 is provided with an opening 13, and the gate 5 is slidably fitted into the opening 13, which facilitates the guidance of the gate 5 and makes its movement more stable and smooth.

[0025] As a further feature of this invention, an installation bracket 6 is fixedly connected inside the opening 13, and a sealing strip 7 is fixedly connected to the bottom of the installation bracket 6. The sealing strip 7 is movably abutted against the top of the gate 5.

[0026] As a further feature of this invention, the bottom of the mounting bracket 6 is threaded with several screws 8, and anti-slip pads 9 are slidably fitted on the outer side of the screws 8. The top of the sealing strip 7 has multiple through holes, and the screws 8 are slidably fitted in the corresponding through holes. The anti-slip pads 9 are movably abutted between the sealing strip 7 and the screws 8.

[0027] The above solution facilitates the disassembly and assembly of the sealing strip 7 by using the mounting bracket 6, screws 8, and anti-slip pads 9, making it easy to replace damaged sealing strips 7 in a timely manner and preventing damage to the sealing strip 7 from reducing its sealing performance.

[0028] As a further feature of this utility model, a lower wedge-shaped top block 12 is fixedly connected to the bottom inner wall and one side inner wall of the gate housing 1, and an upper wedge-shaped top block 10 is fixedly connected to the bottom left side and right top side of the gate 5, with the upper wedge-shaped top block 10 movably abutting against the inclined surface of the corresponding lower wedge-shaped top block 12.

[0029] As a further aspect of this utility model, a fixing screw 11 is threadedly connected to the bottom inner wall and one side inner wall of the gate housing 1, and two wedge-shaped top blocks 12 are respectively fixedly connected to the bottom inner wall and one side inner wall of the gate housing 1 by the fixing screw 11.

[0030] Using the above scheme: when the gate 5 is closed, it will drive the upper wedge-shaped top block 10 to move to the left and slide on the inclined surface of the lower wedge-shaped top block 12. Then, under the squeezing and lifting of the lower wedge-shaped top block 12, the compression of the sealing strip 7 will increase, thereby improving the sealing performance.

[0031] In this invention, during operation, the hydraulic station provides power to the hydraulic cylinder 2, which in turn drives the piston rod 21 to extend. The piston rod 21 then moves the gate 5 to the left to block and close the opening 13. When the gate 5 is closed to the position of the left position switch 3, the left position switch 3 sends a signal to stop the hydraulic oil supply. When the gate 5 is opened to the right position switch 4, the right position switch 4 (also known as the limit switch) sends a signal to stop the hydraulic oil supply, thereby achieving the control of opening and closing the gate 5.

[0032] When the gate 5 is closed, it will cause the upper wedge-shaped top block 10 to move to the left and slide on the inclined surface of the lower wedge-shaped top block 12. Then, under the squeezing and lifting of the lower wedge-shaped top block 12, the compression of the sealing strip 7 will increase, thus improving the sealing performance. The hydraulic cylinder 2 has a built-in structure, and the gate 5 does not extend out of the gate housing 1 when it is open. The equipment has fewer opening positions, making the structure more compact and the installation space smaller.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
