Description

Technical Field

[0001] This invention relates to the field of gate auxiliary tools, and in particular to a gate control device. Background Technology

[0002] Planar gates are commonly used water-retaining structures in water conservancy and hydropower projects and industrial waterways. Their main function is to block or open the flow channel through lifting and lowering movements. Normally, when the gate is in the working state, it is lowered to the gate position to block the water flow. When the gate is not in the working state, it is raised to a high position to allow water flow or keep the channel open. In existing gate opening and closing systems, most use winches in conjunction with wire ropes to pull the gate up and down. When the gate is in the open high position, that is, when the gate is not in the working state, the entire self-weight load of the gate will be borne by the wire rope and winch system for a long time.

[0003] However, when the gate is in a non-working state for a long time, the wire rope and winch are continuously subjected to static tensile loads, which can easily lead to metal fatigue, creep or brake failure, resulting in a shortened equipment life or even the safety hazard of the gate falling unexpectedly. In addition, if a fixed supporting beam is set to support the gate after it is opened in order to protect the opening and closing equipment, although the stress on the wire rope can be eliminated, the fixed structure will occupy the gate's lifting path, making it impossible for the gate to switch from the non-working state to the working state, that is, it cannot fall to close, which seriously affects the normal opening and closing function of the gate. Therefore, we urgently need a device that can bear the gate load in the non-working state to protect the opening and closing equipment, and automatically avoid the gate in the working state to allow the gate to pass normally. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to balance the load protection of the opening and closing equipment when the gate is in a non-working state and the normal operation requirements of the gate in a working state.

[0005] The above-mentioned technical problems are solved by the following technical solution: This invention proposes a gate control device, which includes a receiving beam having a first surface and a second surface opposite to each other; a support seat located below the second surface, and the projection area of ​​the second surface of the receiving beam in the direction of gravity at least partially overlaps with the support seat; a movable component is also provided on the receiving beam to control the position of the receiving beam; when the gate is in a non-working state, by moving the receiving beam below the gate, the gate falls on the first surface of the receiving beam, and the support seat bears the self-weight load of the gate; when the gate is in a pre-working state, the receiving beam is moved to avoid obstruction, so as to allow the passage of the gate.

[0006] In a preferred embodiment of the gate control device of the present invention: the moving part includes a connecting plate connected to the receiving beam; the moving part also includes a pulley that is movably engaged with the support seat.

[0007] In a preferred embodiment of the gate control device of the present invention: a connecting frame is provided on the pulley, and a connecting column is provided on the connecting frame.

[0008] In a preferred embodiment of the gate control device of the present invention: a sliding groove is provided on the connecting plate, and the sliding groove is movably engaged with the connecting column.

[0009] In a preferred embodiment of the gate control device of the present invention: an elastic element is sleeved on the outer wall of the connecting column; and the elastic element is located between the connecting plate and the connecting frame.

[0010] In a preferred embodiment of the gate control device of the present invention: the support base is provided with a slide rail, and the slide rail is movably engaged with the pulley.

[0011] In a preferred embodiment of the gate control device of the present invention: a limit block is provided on the slide rail, and the limit block abuts against the pulley.

[0012] In a preferred embodiment of the gate control device of the present invention, the gate control device further includes a drive component connected to the supporting beam or the moving component.

[0013] In a preferred embodiment of the gate control device of the present invention: the driving component is a hydraulic cylinder, and the output end is connected to the supporting beam or the moving component.

[0014] In a preferred embodiment of the gate control device of the present invention: a connecting seat is provided on one side of the receiving beam, and the hydraulic cylinder is movably connected to the connecting seat.

[0015] The beneficial effects of this invention are as follows: By setting up a supporting beam, when the gate is not in operation, in order to avoid the gate being suspended for a long time and its own weight being entirely borne by the wire rope and winch, which would cause safety hazards, the gate can be started and placed on the supporting beam, so that the weight can be borne by the support seat. When it is necessary to lower the gate to close the gate, the position of the supporting beam can be moved by activating the hydraulic cylinder, so that it is offset from the gate, so as not to affect the lowering and opening of the gate. This setting greatly improves the overall safety of use. Attached Figure Description

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0019] Reference Figures 1-5 This embodiment provides a gate control device, which includes: a supporting beam 1 having a first surface 11 and a second surface 12 facing each other; and a support 2 located below the second surface 12, wherein the projection area of ​​the second surface 12 of the supporting beam 1 in the direction of gravity at least partially overlaps with the support 2; and a movable member 3 is also provided on the supporting beam 1 to control the position of the supporting beam 1. Among them, such as Figure 2 As shown, the supporting beam 1 is preferably configured as an I-beam, and the area of ​​its first surface 11 and second surface 12 can be set to be relatively wide to distribute the pressure and thus improve the stability of the support. Furthermore, the support base 2 can utilize building components such as walls and ground around the gate installation environment to provide better support. The projection area of ​​the second surface 12 of the supporting beam 1 in the direction of gravity at least partially overlaps with the support base 2. That is to say, with the supporting beam 1 as the medium, when the gate falls on the first surface 11 of the supporting beam 1, the supporting beam 1 further falls on the support base 2, and its second surface 12 must at least overlap with the support base 2 in order to complete the transfer of the gate's self-weight load and be supported by the support base 2.

[0020] Furthermore, the movable parts 3 are preferably arranged symmetrically in two sets, distributed on both sides of the supporting beam 1. The movable parts 2 are mainly used to move and adjust the position of the supporting beam 1, thereby controlling whether the gate can pass.

[0021] When the gate is in a non-working state, that is, when the gate is suspended, by moving the supporting beam 1 to below the gate, the gate falls on the first surface 11 of the supporting beam 1, and the support seat 2 bears the self-weight load of the gate. When the gate is in the pre-operation state, that is, when the gate is ready to start working and close the gate, the position of the moving support beam 1 is offset from that of the gate to allow passage.

[0022] In one embodiment provided in this application, the movable component 3 includes a connecting plate 31 connected to the supporting beam 1; the movable component 3 also includes a pulley 32 that is movably engaged with the support base 2.

[0023] Furthermore, by setting pulley 32 to roll in cooperation with support seat 2, the position of the supporting beam 1 can be flexibly adjusted, and the tensile burden can be reduced more than dragging the supporting beam 1.

[0024] In one embodiment provided in this application, a connecting frame 321 is provided on the pulley 32, and a connecting post 33 is provided on the connecting frame 321. A sliding groove 311 is provided on the connecting plate 31, and the sliding groove 311 is movably engaged with the connecting post 33. Figure 4 As shown, the outer wall of the connecting column 33 is also fitted with an elastic element 34; and the elastic element 34 is located between the connecting plate 31 and the connecting frame 321, and the elastic element 34 is preferably a compression spring.

[0025] The slide 311 is used to control the moving direction of the connecting plate 31. Under the action of the elastic element 34, the supporting beam 1 moves up and down. Specifically, when the gate falls on the supporting beam 1, the elastic element 34 is compressed, and the supporting beam 1 falls on the support seat 2, which bears the weight of the gate. When the gate is lifted, the elastic element 34 rebounds, which can suspend the supporting beam 1 in the air. This makes it easy to move the supporting beam 1 through the pulley 32 so that it is offset from the gate position, and then the gate can fall down to close the gate.

[0026] Preferably, a protective cover may be provided around the elastic member 34 to prevent foreign objects from entering and affecting the reset.

[0027] In one embodiment provided in this application, the support base 2 is provided with a slide rail 21, the slide rail 21 is movably engaged with the pulley 32, and a limit block 211 is provided on the slide rail 21, and the limit block 211 abuts against the pulley 32.

[0028] It should be further explained that the limiting block 211 is preferably disposed at the end of the slide rail 21 and cooperates with the pulley 32, such as Figure 3 As shown, the limiting block 211 can be used to prevent the receiving beam 1 from derailing when it is pushed.

[0029] In one embodiment provided in this application, the gate control device further includes a drive member 4 connected to the receiving beam 1 or the moving member 3, wherein the drive member 4 is preferably a hydraulic cylinder 41.

[0030] The output end of the hydraulic cylinder 41 is connected to the supporting beam 1 or the moving part 3. Specifically, the output end of the hydraulic cylinder 41 can be connected to the connecting plate 31 in the moving part 3.

[0031] It should be further noted that, in this solution, the use of other pushing devices such as cylinders is not excluded.

[0032] In one embodiment provided in this application, such as Figure 4 As shown, a connecting seat 5 is provided on one side of the supporting beam 1. The connecting seat 5 is preferably perpendicular to the supporting seat 1, and the hydraulic cylinder 41 is movably connected to the connecting seat 5.

[0033] The connecting seat 5 can utilize building components such as walls and ground around the gate to install the hydraulic cylinder 41. The cylinder barrel of the hydraulic cylinder 41 can be hinged to the connecting seat 5. Figure 5 As shown, it can then swing up and down with the receiving beam 1, thereby achieving forward and backward pushing control of the receiving beam 1.

[0034] In summary, by setting up the supporting beam 1, the load transfer of the gate's own weight can be realized, avoiding the gate being suspended by the steel wire rope and winch load for a long time. As a result, the gate falls on the supporting beam 1 and is supported by the support seat 2. When the gate needs to perform the gate closing action, only the supporting beam 1 needs to be moved, which is very convenient.

[0035] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
