Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering facilities, and in particular to a novel intelligent gate locking beam for extremely humid environments and a control method thereof. Background Art

[0002] The gate locking beam is a core component used to stably fix the gate in a specified position in water conservancy facilities. Its reliability plays a vital role in the safe operation of water conservancy projects. In actual applications, the locking beam is in an extremely humid environment for a long time. In this environment, a large amount of water vapor, corrosive gases, salt spray and other substances in the air will undergo complex electrochemical corrosion reactions with the metal material of the locking beam, resulting in the destruction of the protective layer on the surface of the locking beam, which in turn causes a series of serious problems. Among them, the spring's elastic modulus changes and fatigue strength decreases due to rust, and eventually elastic failure occurs; the internal raceway and ball surface of the rolling bearing are rusted, which increases the friction coefficient and causes jamming; under the action of corrosion, the effective load-bearing cross-sectional area of the bolt is reduced, and the stress concentration is aggravated, resulting in a significantly increased risk of bolt breakage; at the same time, the overall strength of the structure deteriorates due to rust, which seriously threatens the stability of the locking beam.

[0003] Not only that, in waters such as rivers, lakes, etc., external forces such as waves and water flow impacts frequently act. When the gate is subjected to such external forces, it will shake, and the connection between the locking beam and the gate is prone to loosening under repeated shaking and impact, which in turn causes the locking beam to move. Once the locking beam moves, it will not be able to perform its function of fixing the gate normally, posing a huge safety hazard to the water conservancy project and surrounding areas. Summary of the Invention

[0005] The embodiment of the present invention is achieved as follows:

[0006] An embodiment of the present invention provides a novel intelligent gate locking beam for extremely humid environments, which includes a locking beam body, a hydraulic pump station, and an electrical control cabinet;

[0007] A first slider and a second slider are respectively provided at both ends of the locking beam body. The first slider and the second slider are parallel to and spaced apart from each other. The two ends of the locking beam body are respectively fixedly connected to the first slider and the second slider. The bottoms of the first slider and the second slider are both slidably connected to slideways.

[0008] A first driving cylinder and a second driving cylinder are provided on one side of the locking beam body, which are parallel to and spaced apart from each other.

[0012] In this arrangement, the first L-shaped connecting member and the second L-shaped connecting member can not only support the locking beam body, but also connect the telescopic rods of the first driving cylinder and the second driving cylinder, so that the telescopic rods of the first driving cylinder and the second driving cylinder can drive the locking beam body to slide on the slide, thereby facilitating the stable fixing of the gate in the specified position.

[0013] Optionally: a first buffer support device and a second buffer support device are respectively arranged between the above-mentioned first L-shaped connecting member and the above-mentioned second L-shaped connecting member and the two ends of the above-mentioned locking beam body, the bottom ends of the above-mentioned first buffer support device and the above-mentioned second buffer support device are respectively pressed against the above-mentioned first L-shaped connecting member and the above-mentioned second L-shaped connecting member, and the top ends of the above-mentioned first buffer support device and the above-mentioned second buffer support device are telescopically supported on the bottom surfaces of the two ends of the above-mentioned locking beam body.

[0014] In this arrangement, the first buffer support device and the second buffer support device have adaptive buffering and resetting functions. The first buffer support device and the second buffer support device are installed at both ends of the locking beam body and can withstand the weight and impact transmitted by the locking beam body.

[0015] Optionally, the first buffer support device and the second buffer support device both have a base, an outer sleeve is fixedly connected to the base, a coaxial inner sleeve is provided inside the outer sleeve, a sealing end cap is provided at one end of the inner sleeve away from the base, the sealing end cap is sealably connected to the end of the outer sleeve away from the base, a piston rod is sealably passed through the axis of the sealing end cap, and the end of the piston rod close to the base is inserted into the inner sleeve;

[0016] A slidable elastic pressure ring is sleeved in the annular gap between the inner sleeve and the outer sleeve, and the upper and lower parts of the elastic pressure ring respectively have an elastic cavity and a non-elastic cavity. A spring is sleeved inside the elastic cavity, and the two ends of the spring elastically press against the elastic pressure ring and the sealing end cover respectively;

[0017] The inner sleeve is provided with a rod cavity and a rodless cavity. The rod cavity is provided with a piston. The outer wall of the piston is in sealing sliding engagement with the inner wall of the inner sleeve. The piston is fixedly connected to one end of the piston rod close to the base.

[0018] A plurality of first throttle holes are opened on the tube wall of the inner sleeve between the rodless cavity and the non-elastic cavity, and a plurality of second throttle holes are opened on the tube wall of the inner sleeve between the rod cavity and the elastic cavity;

[0019] One end of the piston rod away from the base is detachably connected to a pressure plate, and the elastic cavity, the non-elastic cavity, the rod cavity and the rodless cavity are all filled with hydraulic oil.

[0020] With such arrangement, when the locking beam body is subjected to the gate pressure, the pressure is transmitted to the piston through the piston rod, and the piston compresses the hydraulic oil in the rodless chamber. The hydraulic oil in the rodless chamber then flows to the non-elastic chamber through the first throttle hole, and continues to apply pressure to the elastic pressure ring and the spring. The spring is compressed and deformed after being compressed, and the space in the elastic chamber is thereby reduced. Under the action of pressure, the hydraulic oil in the elastic chamber flows to the rod chamber through the second throttle hole.

Finally, the above-mentioned locking beam body returns to its initial position.

[0021] Optionally, a weighing device is clamped between the first buffer support device, the second buffer support device, the first L-shaped connector, and the second L-shaped connector, and the weighing device is electrically connected to the electrical control cabinet.

[0022] In this way, the weighing device is used to detect whether the locking beam body carries the gate, and to judge the unlocking conditions in the electronic control logic to prevent erroneous operation when the locking beam body carries the gate, thereby avoiding the locking beam body from accidentally exiting the locked state.

[0023] Optionally, the first slider and the second slider are both rectangular grooves, the slideway is horseshoe-shaped, and the first slider and the second slider can be slidably clamped on the slideway.

[0024] Such an arrangement, by adopting a sliding displacement form, effectively reduces the resistance during sliding friction and prevents the components from rusting and becoming stuck in a humid environment.

[0025] Optionally, the two ends of the locking beam body are respectively fixedly connected with a first movement auxiliary rod and a second movement auxiliary rod.

[0026] Such an arrangement ensures that when the automation system fails, the connection between the first driving cylinder and the second driving cylinder and the locking beam body can be manually disconnected, and the locking beam body can be easily moved by manually pushing the first moving auxiliary rod and the second moving auxiliary rod.

[0027] Optionally, the front end and rear end of the first driving cylinder respectively have a first oil port and a second oil port, and the front end and rear end of the second driving cylinder respectively have a third oil port and a fourth oil port;

[0029] A third hydraulic pipeline is connected between the second oil port and the fourth oil port. The third hydraulic pipeline has a tee. A fourth hydraulic pipeline is connected between the tee and the hydraulic pump station.

[0030] With such arrangement, when the locking beam body needs to stably fix the gate in a specified position, the hydraulic pump station injects high-pressure oil to the second oil port and the fourth oil port through the fourth hydraulic pipeline and the third hydraulic pipeline. At this time, the telescopic rods of the first driving oil cylinder and the second driving oil cylinder push the locking beam body to slide to a suitable position, and the gate is mounted on the locking beam body. When the locking beam body does not need to stably fix the gate in a specified position, the hydraulic pump station injects high-pressure oil to the first oil port and the third oil port through the first hydraulic pipeline and the second hydraulic pipeline. At this time, the telescopic rods of the first driving oil cylinder and the second driving oil cylinder retract, so that the locking beam body slides to the initial position, facilitating the lowering of the gate to close the gate.

[0031] Optionally: the first driving cylinder and the second driving cylinder are both hingedly connected to an articulated seat in the radial direction, a base is provided at the bottom of the articulated seat, and the bottom surface of the articulated seat is rotatably connected to the top surface of the base.

[0039] Optionally, the hydraulic pump station, the electrical control cabinet and the surveillance camera all meet the IP68 protection grade.

[0040] With such a configuration, the IP68 protection level provides high dust and water resistance, making the hydraulic pump station, the electrical control cabinet and the surveillance camera less susceptible to damage.

[0041] In one implementation of this embodiment: a control method for a new intelligent gate locking beam for an extremely humid environment is also provided:

[0042] When the locking beam body is put into operation, the putting-in button of the locking beam body is pressed, and the electronic control system determines whether the locking beam body is in the withdrawn position and whether it bears weight. If the locking beam body is in the withdrawn position and does not bear weight, the electrical control cabinet receives the signal, and the electrical control cabinet electrically controls the hydraulic pump station. The hydraulic pump station injects high-pressure oil into the tail ends of the first driving cylinder and the second driving cylinder respectively through the third hydraulic pipeline and the fourth hydraulic pipeline. The telescopic rods of the first driving cylinder and the second driving cylinder push the locking beam body into place. After the electronic control system receives the put-in-place signal, the gate is lowered, and the locking ear plate on the gate is pressed on the locking beam body. The weighing device detects the pressure and transmits it to the electronic control system by telecommunication, and the electronic control system control equipment loses power.

[0043] When the locking beam body is withdrawn, the withdrawal button of the locking beam body is pressed, and the electronic control system determines whether the locking beam body is in the input position and whether it bears weight. When the locking beam body is in the input position and bears weight, the electrical control cabinet receives the signal, and the electrical control cabinet electrically controls the hydraulic pump station. The hydraulic pump station injects high-pressure oil into the head ends of the first driving cylinder and the second driving cylinder through the first hydraulic pipeline and the second hydraulic pipeline respectively. The telescopic rods of the first driving cylinder and the second driving cylinder pull the locking beam body back into position. After the electronic control system receives the return signal, the electronic control system control device loses power.

At this time, it is convenient for manpower to push the locking beam body 1 to move.

[0071] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 A monitoring camera (not shown in the figure) is provided on the side of the locking beam body 1 away from the first driving cylinder 7 and the second driving cylinder 8. The monitoring camera is installed on the outside of the locking beam body 1 to monitor the displacement of the locking beam body 1 and transmit the monitoring image to the gate hoist to facilitate remote operation and observation by the driver.

[0072] The outer wall of the locking beam body 1 adopts a zinc spraying anti-corrosion process, which can effectively prevent the locking beam body 1 from rusting in an extremely humid environment and improve the corrosion resistance of the locking beam body 1.

[0073] A wireless control transmission system (not shown) is provided inside the electrical control cabinet 3, so that the operator can remotely control the system from the driver's cab.

[0074] The hydraulic pump station 2, the electrical control cabinet 3 and the surveillance camera all reach the IP68 protection grade. The IP68 protection grade has high dustproof and waterproof properties, making the hydraulic pump station 2, the electrical control cabinet 3 and the surveillance camera not easily damaged.

[0075] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In one implementation of this embodiment: a control method for a new type of intelligent gate locking beam for an extremely humid environment is also provided:

[0076] When the locking beam body 1 is put into operation, the insertion button of the locking beam body 1 is pressed, and the electronic control system determines whether the locking beam body 1 is in the withdrawal position and whether it is load-bearing. If the locking beam body 1 is in the withdrawal position and is not load-bearing, the electrical control cabinet 3 receives the signal, and the electrical control cabinet 3 electrically controls the hydraulic pump station 2. The hydraulic pump station 2 injects high-pressure oil into the tail ends of the first driving cylinder 7 and the second driving cylinder 8 through the third hydraulic pipeline 37 and the fourth hydraulic pipeline 39 respectively. The telescopic rods of the first driving cylinder 7 and the second driving cylinder 8 push the locking beam body 1 into place. After the electronic control system receives the insertion into place signal, the gate is lowered, and the locking ear plate on the gate is pressed on the locking beam body 1. The weighing device 28 detects the pressure and transmits it to the electronic control system by telecommunication, and the electronic control system control equipment loses power.

[0077] When the locking beam body 1 is withdrawn, the withdrawal button of the locking beam body 1 is pressed, and the electronic control system determines whether the locking beam body 1 is in the input position and whether it is load-bearing. When the locking beam body 1 is in the input position and load-bearing, the electrical control cabinet 3 receives the signal, and the electrical control cabinet 3 electrically controls the hydraulic pump station 2. The hydraulic pump station 2 injects high-pressure oil into the head ends of the first driving cylinder 7 and the second driving cylinder 8 through the first hydraulic pipeline 35 and the second hydraulic pipeline 36 respectively. The telescopic rods of the first driving cylinder 7 and the second driving cylinder 8 pull the locking beam body 1 back into position. After the electronic control system receives the return signal, the electronic control system control device loses power.

[0078] Before the locking beam body 1 moves, the gate needs to be hoisted to prevent the gate from being erected on the locking beam body 1, otherwise the locking beam cannot be controlled.

[0079] In this embodiment, a filling hole 56 is radially opened on the outer wall of the outer sleeve 14. The filling hole 56 facilitates the staff to inject hydraulic oil into the first buffer support device 11 and the second buffer support device 12, or to discharge the hydraulic oil inside the first buffer support device 11 and the second buffer support device 12, so as to facilitate replacement or maintenance.

[0080] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In this embodiment, the locking beam body 1 is made of Q355 material, all connection parts are made of stainless steel bolts, and the locking beam body 1 is treated with zinc spraying anti-corrosion process, which can effectively prevent rust in extremely humid environments and improve the corrosion resistance of the locking beam body 1.

[0081] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In this embodiment, in order to prevent the rolling bearing from rusting and getting stuck in a humid environment, a sliding displacement form is adopted between the locking beam body 1 and the slide 6. A first slider 4 and a second slider 5 made of a high-strength and wear-resistant composite material are installed at the bottom of the locking beam body 1. The friction surfaces of the first slider 4 and the second slider 5 have a self-lubricating function, which can effectively reduce the resistance during sliding friction. The slide 6 adopts a horseshoe shape with a smooth transition at the edge. A certain distance gap is reserved on both sides of the first slider 4 and the second slider 5 and the slide 6 to prevent the locking beam body 1 from deflecting and getting stuck.

[0082] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8In this embodiment, in order to prevent the gate from shaking under the action of external forces such as surges and causing the locking beam body 1 to move, and considering that the locking beam body 1 adopts a sliding form, which increases the friction, a hydraulic pump station 2, a first driving oil cylinder 7 and a second driving oil cylinder 8 are provided to lock the beam body 1 for throwing and retracting; the first driving oil cylinder 7 and the second driving oil cylinder 8 are installed at appropriate positions on both sides of the selected beam, and the telescopic rods of the first driving oil cylinder 7 and the second driving oil cylinder 8 are connected to the locking beam body 1, and the other end is connected to a rotatable hinged seat 40 fixed on a base 41 in the concrete. The hydraulic pump station 2 includes: components such as a motor, an oil pump and valve parts, which are integrated and installed in a tank with an IP68 waterproof grade. The tank is made of stainless steel. The first hydraulic pipeline 35, the second hydraulic pipeline 36, the third hydraulic pipeline 37 and the fourth hydraulic pipeline 39 extend from the tank body and connect the first driving cylinder 7 and the second driving cylinder 8. On the concrete foundation, the first hydraulic pipeline 35, the second hydraulic pipeline 36, the third hydraulic pipeline 37 and the fourth hydraulic pipeline 39 are arranged using seamless steel pipes. At a position about 1.5 meters close to the cylinder, the first hydraulic pipeline 35, the second hydraulic pipeline 36, the third hydraulic pipeline 37 and the fourth hydraulic pipeline 39 are converted into high-pressure hoses and connected to the first driving cylinder 7 or the second driving cylinder 8. In addition, the hydraulic pump station 2 is equipped with an emergency external pressure interface, which can be connected to an external emergency pump station as a temporary power source in the event of oil pump damage.

[0083] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In this embodiment, a hydraulic system control box is set at a suitable position near the locking beam. The electrical control cabinet 3 has IP68 waterproof function and is made of stainless steel. The cables, power supply cables, and camera image transmission cables between the hydraulic pump station 2 and the control box are all axially sealed cables to isolate water vapor from entering the box. The electrical control cabinet 3 has a built-in wireless control transmission system, allowing the operator to remotely control it in the driver's cab. At the same time, the waterproof camera arranged on site transmits real-time monitoring images to the image monitoring screen in the driver's cab. The driver can monitor the entire process of throwing and retracting the locking beam and stop immediately if any abnormal situation is found.
