Description

Technical Field

[0001] The present invention relates to the technical field of vertical lift gates, and in particular to an auxiliary braking device for vertical lift gates. Background Art

[0002] Gates are an important component of hydraulic structures and can be divided into service gates, emergency gates, and maintenance gates according to their function. A vertical lift gate is a type of service gate that can be opened and closed in moving water to control water levels and regulate flow.

[0003] Vertical gates are often opened and closed using a fixed winch hoist as a sling connected to the gate. The fixed winch hoist rotates the drum through a gear transmission system, retracting and releasing the wire rope, which in turn drives the vertical gate up and down. It is simple in structure, easy to manufacture, and convenient to maintain and repair.

[0004] However, fixed winch hoists do not have a self-locking function. This means that whether they are manually or electrically operated, they must be equipped with a reliable braking device to automatically maintain the stable position of the vertical gate when stationary. Without a reliable braking device, the vertical gate may fall due to its own weight, posing a safety hazard.

[0005] During flood seasons and when floods are imminent, existing methods for ensuring the stable opening of vertical gates and preventing them from slipping include using a lever to secure the motor spindle to lock the vertical gates, or hanging a sling from the upper end of the vertical gates to secure them. However, these methods significantly damage the lifting equipment and can even pose safety risks.

[0006] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be considered as an admission or any form of suggestion that the information constitutes the prior art already known to a person of ordinary skill in the art. Summary of the Invention

[0007] Purpose of the invention: The technical problem to be solved by the present invention is to provide an auxiliary braking device for a vertical lift gate in response to the deficiencies of the existing technology, which can prevent the vertical lift gate from sliding down and being damaged, and also avoid damage to the vertical lift gate caused by excessive lateral pressure.

[0008] In order to solve the above technical problems, the present invention discloses an auxiliary braking device for a vertical lift gate, wherein the vertical lift gate is arranged in the gate slot in a liftable manner. The auxiliary braking device includes:

[0009] a hydraulic separation crane configured to apply lateral pressure to the vertical lift gate so that the vertical lift gate is pressed against the gate slot and fixed;

[0010] an electric pump connected to a fluid inlet of the hydraulic separation crane and configured to supply hydraulic fluid to the fluid inlet of the hydraulic separation crane at a hydraulic pressure;

[0011] and a regulating valve provided on a pipeline connecting the fluid inlet of the hydraulic separation crane and the outlet of the electric pump; the auxiliary braking device is configured to adjust the pressure level of the hydraulic fluid in the hydraulic separation crane by adjusting the opening of the regulating valve to adjust the lateral pressure.

[0012] In some embodiments, the auxiliary braking device further includes a solenoid valve, which is provided on a pipeline connecting the outlet of the electric pump and the inlet of the regulating valve to achieve controllable on-off communication between the electric pump and the fluid inlet of the hydraulic separation crane.

[0013] In some embodiments, the auxiliary brake device includes a hydraulic pressure gauge connected to an outlet of the electric pump for detecting the hydraulic pressure of the hydraulic fluid supplied by the electric pump to a fluid inlet of the hydraulic separation crane.

[0014] In some embodiments, the hydraulic separation crane is provided with two concrete foundations on the waterfront side of the vertical lift gate.

[0015] In some embodiments, a friction enhancement structure is provided between the vertical lift gate and the gate slot.

[0016] Specifically, the friction enhancement structure includes a P-type rubber sealing belt, and the P-type rubber sealing belt is fixedly connected to the vertical lifting gate.

[0017] More specifically, an embedded steel component is installed in the door groove, and the door groove is pressed and fixed with the P-type rubber sealing belt on the vertical lifting gate through the embedded steel component.

[0018] In some embodiments, the auxiliary brake device further comprises an oil tank for containing the hydraulic fluid, wherein the oil tank outlet is connected to the inlet of the electric pump, and the oil tank inlet is connected to the fluid outlet of the hydraulic separation crane;

[0019] The inlet and outlet of the oil tank and the liquid inlet and outlet of the hydraulic separation crane are also respectively provided with switch valves. These switch valves are convenient for maintenance and replacement of each part.

[0020] In some embodiments, the auxiliary braking device includes a pressure sensor installed in an operating portion of the hydraulic separation crane for abutting against the door groove; the pressure sensor is configured to detect the lateral pressure.

[0021] In some embodiments, the auxiliary braking device includes a relative displacement detection device, which is configured to detect the relative sliding displacement between the vertical lifting gate and the gate slot; the auxiliary braking device is configured to adjust the opening of the regulating valve according to the detection result of the relative displacement detection device.

[0022] Beneficial effects:

[0023] The present invention provides an auxiliary braking device for a vertical lift gate. When relative displacement occurs between the vertical lift gate and the threshold, the device can control the opening of a regulating valve to adjust the pressure level of the hydraulic fluid in the hydraulic separation crane, thereby adjusting the lateral pressure applied by the hydraulic separation crane to the vertical lift gate.

[0029] See also Figures 1 to 2 The present invention discloses an auxiliary braking device for a vertical lifting gate, which includes a hydraulic separation crane 1, an electric pump 6 and a regulating valve 7.

[0030] The hydraulic separation crane 1 is configured to apply lateral pressure to the vertical lift gate 3 so that the vertical lift gate 3 is pressed against the gate groove 5 and fixed.

[0031] The electric pump 6 is connected to the fluid inlet of the hydraulic separation crane 1 and is configured to supply hydraulic fluid to the fluid inlet of the hydraulic separation crane 1 at a hydraulic pressure.

[0032] The regulating valve 7 is provided on the pipeline connecting the fluid inlet of the hydraulic separation crane 1 and the outlet of the electric pump 6; the auxiliary braking device is configured to adjust the pressure level of the hydraulic fluid in the hydraulic separation crane 1 by adjusting the opening of the regulating valve 7 to adjust the lateral pressure.

[0033] Figure 1 The arrows in the middle represent the flow direction of the hydraulic fluid.

[0034] In one embodiment, see Figure 1 The vertical lift gate 3 is installed in the gate groove 5 in a liftable manner through a fixed winch type hoist.

[0035] For further information, see Figure 1 The auxiliary braking device further includes a pressure sensor 11 installed in the hydraulic separation crane 1 for contacting the operating portion of the door groove 5; the pressure sensor 11 is configured to detect lateral pressure.

[0036] For further information, see Figure 1 The auxiliary braking device further includes a relative displacement detection device 12, which is configured to detect the relative sliding displacement between the vertical lift gate 3 and the gate slot 5. The auxiliary braking device is configured to control the opening of the regulating valve 7 based on the detection results of the relative displacement detection device 12 and the pressure sensor 11. In some examples, the relative sliding displacement refers to the downward displacement of the vertical lift gate.

[0037] Specifically, the relative displacement detection device 12 includes a magnetostrictive displacement sensor and a magnetic ring. The fixed portion of the magnetostrictive displacement sensor is installed in the door groove 5 , and the magnetic ring is installed on the vertical lift gate 3 .

[0038] For details, see Figure 1 The auxiliary braking device includes a controller 13, and the regulating valve 7, the relative displacement detection device 12 and the pressure sensor 11 are electrically connected to the controller 13. The controller 13 is configured to control the opening of the regulating valve 7 according to the detection results of the relative displacement detection device 12 and the pressure sensor 11.

[0039] Further, see Figure 1 The auxiliary braking device also includes a solenoid valve 8, which is arranged on a pipeline connecting the outlet of the electric pump 6 and the inlet of the regulating valve 7 to achieve controllable on-off communication between the outlet of the electric pump 6 and the liquid inlet of the hydraulic separation crane 1.

[0040] For details, see Figure 1The auxiliary brake device includes a hydraulic pressure meter 19 connected to the outlet of the electric pump 6 for detecting the hydraulic pressure of the hydraulic fluid supplied by the electric pump 6 to the fluid inlet of the hydraulic separation crane 1.

[0041] For details, see Figure 1 The hydraulic separation crane 1 is provided with two concrete foundations 17 on the water-facing side, both of which are installed on one side of the vertical lifting gate 3 .

[0042] It should be understood that the number of the hydraulic separation cranes 1 in this embodiment is not limited to two, but can be multiple.

[0043] Specifically, in order to generate a sufficiently large static friction force, a friction enhancement structure is provided between the vertical lift gate 3 and the gate slot 5. The friction enhancement structure is located on a side of the vertical lift gate 3 away from the hydraulic separation crane 1.

[0044] For details, see Figure 1 The friction enhancement structure includes a P-type rubber sealing belt 4, which is fixedly connected to the vertical lifting gate 3.

[0045] by Figure 1 For example, the hydraulic separation crane 1 presses against the front of the vertical lift gate 3. Accordingly, the P-type rubber sealing strip 4 on the back of the vertical lift gate 3 for contacting the gate groove 5 is provided on the back of the vertical lift gate 3. The P-type rubber sealing strip extends from the top end of the vertical lift gate 3 to the bottom end of the vertical lift gate 3. Figure 1 The structure of the P-type rubber sealing belt 4 cannot be shown.

[0046] It should be understood that a P-type rubber sealing belt 4 can also be provided between the vertical lift gate 3 and the hydraulic separation crane 1. The P-type rubber sealing belt 4 is fixedly mounted on the vertical lift gate 3. Figure 1 shown.

[0047] For details, see Figure 1 An embedded steel member 9 is installed in the gate groove 5, and the gate groove 5 is pressed and fixed to the vertical lift gate 3 by the embedded steel member 9. For the embodiment with a P-type rubber sealing strip 4, the vertical lift gate 3 is pressed and fixed by the P-type rubber sealing strip 4 against the embedded steel member 9, thereby achieving the pressing and fixing between the gate groove 5 and the vertical lift gate 3.

[0048] For further information, see Figure 1The auxiliary brake device also includes an oil tank 18 for containing the hydraulic fluid. The outlet of the oil tank 18 is connected to the inlet of the electric pump 6, which in turn is connected to the fluid outlet of the hydraulic separation crane 1. On-off valves 10 are also provided at the inlet and outlet of the oil tank 18, as well as the fluid inlet and outlet of the hydraulic separation crane 1. These on-off valves 10 facilitate maintenance and replacement of various components. During normal use, these on-off valves 10 are in the open state.

[0049] In a specific embodiment, the controller 13 of this device is a PLC controller. The PLC controller analyzes the data transmitted by various sensors and, by controlling the on / off operation of the electric pump 6 and the opening of the regulating valve 7, appropriately increases or decreases the pressure of the hydraulic separation crane 1. This maintains a high friction force between the P-type rubber sealing strip on the vertical lift gate and the embedded steel member 9 in the gate slot 5, stabilizing the vertical lift gate's open state. The controller also transmits relevant data to the host computer 14. More specifically, when the vertical lift gate opens to a set height, the device is powered on, and the PLC controller initializes each sensor and establishes communication. The PLC controller activates the electric pump 6 and solenoid valve 8 according to the settings, supplying high-pressure oil, or hydraulic fluid, to the hydraulic separation cranes 1 on both sides of the vertical lift gate through pipes. This causes the pistons, or operating components, of the hydraulic separation cranes 1 to generate pressure against the vertical lift gate body, forcing the P-type rubber sealing strip 4 on one side of the vertical lift gate to tightly press against the embedded steel member 9 in the gate slot 5. The resulting tremendous friction holds the vertical lift gate firmly in place, thus achieving an auxiliary braking effect. If the vertical lift gate slides downward for any reason, the relative displacement detection device 12 installed on the vertical lift gate immediately sends a signal to the PLC controller. The PLC controller, in response to the signal, activates the electric pump 6 and regulating valve 7 to increase piston pressure, increasing friction and preventing the vertical lift gate from sliding downward. Simultaneously, the PLC controller receives detection signals from the pressure sensor 11 installed on the hydraulic separation crane 1 to control the hydraulic fluid output capacity and prevent excessive piston pressure. In an embodiment in which multiple hydraulic separation cranes 1 are provided, the PLC controller sends relevant signals to the host computer 14. The host computer 14 determines whether the vertical lifting gate has slipped or tilted on one side based on the received signals. In both cases, the host computer 14 will control the alarm 15 to sound an alarm.

[0050] In some embodiments, see Figure 2 , further comprising a touch screen 16, which is electrically connected to the host computer 14. The touch screen 16 is used to control the pressure, start and stop, and to display data such as pressure and alarms. No keyboard is required, which is convenient and fast.

[0051] In some embodiments, the preferred models of the various components of the device are as follows: the hydraulic separation crane 1 adopts the Shanghai Industrial RSC-201 series products and the electric pump 6 series supporting products, and the manufacturer is Shanghai Yiying Crane Machinery Co., Ltd.; the magnetostrictive displacement sensor adopts the Zhejiang Da Jingyi E series products, and the manufacturer is Zhejiang Hangzhou Zhejiang Da Jingyi Mechanical and Electrical Technology Co., Ltd.; the pressure sensor 11 adopts the Dijia Sensing DJYZ series products, and the manufacturer is Shanghai Dijia Sensing Technology Co., Ltd.; the solenoid valve 8 adopts the Lidian solenoid valve LD87H series products, and the manufacturer is Shanghai Lidian Solenoid Valve Co., Ltd.; the switch valve 10 adopts the Zhongli Valve GJ11Y series products, and the manufacturer is Jiangsu Zhongli Valve Co., Ltd.; the regulating valve 7 adopts the TL900-DL series products, and the manufacturer is Shanghai Julang Valve Group; the PLC controller adopts the Siemens 2000 series.

[0052] Below, refer to Figures 1 to 2 , a method for using the auxiliary braking device for a vertical lift gate of the present invention shown in embodiment 1 during the braking process is described.

[0053] When the vertical lifting gate 3 is lifted to the set position by the fixed winch hoist, the auxiliary braking device is energized, the controller 13 controls the electric pump 6 to start, the solenoid valve 8 is opened, and the regulating valve 7 cooperates with the electric pump 6 to enable the hydraulic separation crane 1 to apply lateral pressure to the vertical lifting gate so that the vertical lifting gate is pressed against the gate groove 5 and fixed.

[0054] When the relative displacement detection device 12 detects relative displacement between the vertical lift gate 3 and the gate slot 5, the controller 13 controls the opening of the regulating valve 7 according to the detection results of the relative displacement detection device 12 and the pressure sensor 11 to adjust the pressure level of the hydraulic fluid in the hydraulic separation crane 1, thereby adjusting the lateral pressure applied by the hydraulic separation crane 1 to the vertical lift gate. This lateral pressure presses the vertical lift gate against the gate slot 5 and fixes it, preventing the vertical lift gate from sliding down and also preventing the vertical lift gate from being damaged due to excessive lateral pressure.

[0055] The present invention provides a concept and method for an auxiliary braking device for a vertical lift gate. There are numerous methods and approaches for implementing this technical solution. The above is merely a preferred embodiment of the present invention.

Any components not specified in this embodiment may be implemented using existing technologies.
