Description

Technical Field

[0001] The invention relates to the technical field of hydropower station gates, and in particular to a flexible automatic throwing and retracting device for a locking beam of a hydropower station gate. Background Art

[0002] The gate is an important component of the hydraulic structure of a hydropower station, and plays the role of cutting off water flow, controlling water level, controlling flow through the gate, and discharging sediment.

[0003] In the daily operation of a hydropower station, the opening and closing of the gate is one of the important operations, and the locking beam plays a vital role as a device to ensure the safety and stability of the gate. When the gate is lifted, in order to avoid continuous stress on the wire rope on the gate opening and closing equipment, it is necessary to manually put the gate locking beam into the gate slot base on the platform on both sides of the gate, and then the lifting equipment will drop the gate and place it on the left and right locking beams, so that the opening and closing equipment will no longer be stressed, reducing the risk of damage.

[0004] When the gate needs to be lowered, it is first lifted a certain distance, and then the locking beam is manually withdrawn. At present, most power stations still use manual operation, which cannot achieve remote operation and unattended operation, increasing labor intensity and causing certain risks. Some power stations need to frequently open and close the gate and insert and withdraw the locking beam, which seriously affects their safety and economy. Summary of the invention

[0005] The invention provides a flexible automatic throwing and retracting device for a locking beam of a hydropower station gate, aiming to realize the automatic throwing and retracting of the locking beam and improve the operating efficiency and safety of the hydropower station gate.

[0006] The present invention is realized by the following technical scheme: a hydropower station gate locking beam flexible automatic throw-in and throw-out device, comprising a locking beam and an automatic throw-in and throw-out unit, wherein the two sides of the locking beam are respectively slidably matched with the platforms on the two sides of the gate slot;

[0007] The automatic insertion and withdrawal unit includes a connecting member and a driving member driving the connecting member to move horizontally back and forth. The connecting member is connected to the locking beam. The driving member can drive the locking beam to move below the gate or away from the gate through the connecting member.

[0008] Compared with the prior art, this solution has the following advantages and beneficial effects:

[0009] In this solution, the connecting member is driven to move back and forth horizontally by the driving member in the automatic insertion and withdrawal unit, thereby driving the locking beam connected to the connecting member to move back and forth horizontally. This makes it easy to drive the locking beam to automatically be invested under the gate to support the gate, and it can also be moved away from the gate to facilitate the gate to be inserted into the gate slot again to cut off the water flow.

[0010] This solution can effectively realize the automatic insertion and withdrawal of the locking beam, thereby improving the operating efficiency and safety of the hydropower station gate.

[0011] Furthermore, the driving member includes a motor and a lead screw, a vertical plate and a base are installed on the platform, the vertical plate is vertically connected to the base, and the motor is installed on the base;

[0012] One end of the lead screw is connected to the output shaft of the motor, the other end of the lead screw is rotationally matched with the vertical plate, the connecting piece is threadedly matched with the lead screw, and the connecting piece is slidingly matched with the base.

[0013] Beneficial effect: The driving member in this scheme drives the screw to rotate through the motor, thereby driving the connecting member matched with the screw thread to move horizontally, and then drives the locking beam to move horizontally toward or away from the gate. The driving member in this scheme has a simple structure and drives the locking beam smoothly and efficiently.

[0014] Further, the connecting member includes a left connecting rod, a right connecting rod and a cross slider, one end of the left connecting rod and one end of the right connecting rod are respectively connected to the two ends of the cross slider, and the other end of the left connecting rod and the other end of the right connecting rod are respectively connected to the left and right parts of the locking beam, the cross slider is threadedly matched with the lead screw, and the cross slider is slidably matched with the base.

[0015] Beneficial effects: The two ends of the left connecting rod and the right connecting rod in the connecting member of the present invention are connected to the locking beam and the horizontal slider respectively, and the left connecting rod and the right connecting rod are connected to the left and right parts of the locking beam respectively, so that the gravity of the locking beam can be dispersed, the support of the locking beam is more stable, and the loss of the entire connecting member can be reduced. The structural design of the present invention is compact. The reasonable layout and mutual cooperation of the left connecting rod, the right connecting rod and the horizontal slider make the device have high reliability and stability.

[0016] Furthermore, a left slide cylinder and a right slide cylinder are connected to the platform on one side of the gate slot, and the left connecting rod and the right connecting rod pass through the left slide cylinder and the right slide cylinder respectively.

[0017] Beneficial effects: The left slide cylinder and the right slide cylinder in this solution can guide the movement of the left connecting rod and the right connecting rod, thereby ensuring the stability and straightness of the movement of the two ends of the locking beam.

[0018] Furthermore, the driving member also includes a driver, which is electrically connected to the motor and is used to control the output of the motor. The lead screw is connected with a retracted-in-place switch and an inserted-in-place switch. The position where the connecting member is connected to the lead screw is located between the retracted-in-place switch and the inserted-in-place switch. The retracted-in-place switch and the inserted-in-place switch are both electrically connected to the driver.

[0019] Beneficial effects: In this solution, the retraction switch and the insertion switch are connected to the screw, and the driver outputs signals to control the forward and reverse rotation and start and stop of the motor. When the connecting part touches the retraction switch and the insertion switch, the driver controls the motor to stop output and the locking beam stops moving, thereby realizing the automatic retraction and insertion of the locking beam.

[0020] Furthermore, a fuzzy controller is provided in the driver, and a position sensor is installed on the side of the vertical plate facing the retracted into position switch, and the position sensor detects the position of the connecting part in real time; the position sensor is electrically connected to the fuzzy controller, and the fuzzy controller is used to receive the position signal sent by the position sensor so that the driver can adjust the output of the motor in real time.

[0021] Beneficial effects: In this solution, a position sensor is used to monitor the position of the locking beam in real time and serve as the signal input of the fuzzy controller. Through the fuzzy controller, the output of the stepper motor is adjusted in real time, which shortens the action time of the locking beam and effectively reduces the impact force when contacting the retracted switch and the inserted switch, ensuring the flexibility and accuracy of the locking beam's insertion and retraction process, improving the system's response speed and accuracy, and enhancing the system's reliability and safety.

[0022] Furthermore, the fuzzy controller receives a precise input quantity output from the position sensor, obtains a position deviation and a rate of change of the position deviation as input variables of the fuzzy controller by subtracting the precise input quantity from an expected value, converts the input variable into a fuzzy quantity, determines the fuzzy language value of the input variable and the corresponding membership function, performs reasoning according to a fuzzy rule base established in the fuzzy controller, calculates the fuzzy output corresponding to the fuzzy input, obtains a precise output value based on the defuzzification, adjusts the stepper motor output in real time, reduces the motor output in advance when the locking beam is close to being put into place or retracted, and increases the motor output when the locking beam is far from being put into place or retracted.

[0023] Beneficial effect: In this scheme, the fuzzy control quantity is calculated, and the precise control quantity is obtained through anti-fuzzy transformation. The control quantity controls the motor output in real time to realize the smooth automatic throwing and retraction of the locking beam of the hydropower station. At the same time, the dual protection of the locking beam retracting switch, the locking beam throwing switch and the position sensor makes the automatic throwing and retraction device safer.

[0024] Furthermore, the top end of the locking beam is provided with an inclined surface inclined toward the gate direction, and one or more limiting grooves are provided on the inclined surface, and the gate can be inserted into the limiting grooves.

[0025] Beneficial effect: After the lifting device lifts the gate, it needs to wait for a certain period of time for the locking beam to move to the bottom of the gate. If the lifting device fails, the gate lifting height does not meet the requirements, resulting in the gate lifting being shorter. In this solution, since the top of the locking beam is an inclined surface inclined toward the gate, when the locking beam moves to the gate, the inclined surface of the locking beam will push the gate upward, thereby moving the gate to the corresponding limit groove;

[0026] In addition, the inclined surface and limit groove of the locking beam in this solution have low requirements on the accuracy of the locking beam's support position for the gate. It only requires that the locking beam be located below the gate, and the lifting equipment allows the gate to fall to the inclined surface of the locking beam. The lifting equipment then allows the gate to retain a shorter displacement space. In this way, by driving the locking beam forward again, the inclined surface of the locking beam lifts the gate until it is opposite to the limit groove and is located in the limit groove.

[0027] The setting of the limit groove in this scheme can provide stable support and limit for the gate. At the same time, the setting of multiple limit grooves can change the support height of the gate. At the same time, it is convenient to drive the locking beam to continue to move forward so that the gate can be stuck in the nearest limit groove for locking and support.

[0028] Furthermore, it also includes a locking rod, slideways are provided on the platforms on both sides of the gate slot, and the two sides of the locking beam can respectively slide with the two slideways on the platform; the first slide plate and the second slide plate are connected to both sides of the bottom of the locking beam, and the slideway is located between the first slide plate and the second slide plate; the first slide plate and the second slide plate are provided with plug holes arranged opposite to each other; a through hole is provided at the position of the slideway opposite to the locking beam when it is put into place;

[0029] When the locking beam is put into place, it moves to be directly below the gate. When the locking beam is put into place, the sockets on the first slide and the second slide are aligned with the through holes on the slide, and the locking rod can pass through the socket on the first slide, the through hole on the slide and the socket on the second slide in sequence.

[0030] Beneficial effect: The setting of the slide can provide a guide for the movement of the locking beam and ensure the reliability and stability of the movement of the locking beam; in this solution, a through hole is opened on the slide for the position where the locking beam is put into place, so that when the locking beam is put into the specified position, the locking rod is inserted into the socket on the first slide, the through hole on the slide and the socket on the second slide in sequence, which can further limit the insertion position of the locking beam, improve the stability of the locking beam after it is put into the specified position, thereby improving the stability and reliability of the locking beam when supporting the gate.

[0031] In addition, in this solution, after the socket and the through hole are facing each other, the locking rod can be inserted. The cooperation between the locking rod, the socket and the through hole also plays a certain positioning role in the insertion position of the locking beam. When the locking rod can be inserted into the socket and the through hole, it means that the locking beam has been put into place.

[0032] Furthermore, it also includes an auxiliary support beam, a movable groove is opened at the bottom of the locking beam, the auxiliary support beam is located in the movable groove, the movable groove is a T-shaped groove structure, the top end of the auxiliary support beam is located in the movable groove, and the shape of the auxiliary support beam is adapted to the shape of the movable groove, and there is a distance between the top end of the auxiliary support beam and the top wall of the movable groove under the action of gravity;

[0033] The top of the platform on both sides of the gate slot and the position where the locking beam is put into place are provided with mounting holes, and a main support block is provided in the mounting hole. The mounting hole is a stepped hole, and a spring is connected between the main support block and the bottom of the mounting hole. Under the action of the spring, the top of the main support block is located above the mounting hole;

[0034] Auxiliary support blocks are connected to both sides of the bottom of the auxiliary support beam, and an inclined surface is provided at one end of the auxiliary support block facing the main support block;

[0035] The locking rod is threadedly connected to at least one of the two sockets, and one end of the locking rod facing the auxiliary support block is provided with two conical surfaces that can respectively abut and cooperate with the inclined surfaces of the main support block and the auxiliary support block.

[0036] It plays a supporting role, but because the gate needs to be inserted in the gate slot, the weight of the gate will be concentrated on the position where the locking beam and the gate slot width are consistent. In this way, the gate slot exerts greater pressure on the middle part of the locking beam. Long-term use can easily reduce the bearing capacity of the locking beam and easily cause the risk of collapse and fracture of the locking beam, resulting in the inability to effectively support the gate, which creates potential risks.

[0037] In the present solution, an auxiliary support beam is further provided at the bottom of the locking beam, and the auxiliary support beam is suspended in the moving groove at the bottom of the locking beam under the action of gravity, and mounting holes are opened at the top of the platforms on both sides of the gate groove, and main support blocks are provided in the mounting holes. Under the action of the spring, the top of the main support block is located above the mounting hole, and the main support block and the auxiliary support block at the bottom of the auxiliary support beam are both provided with inclined surfaces. In this way, when the locking beam is put into place, the locking rod is screwed into the plug hole and the through-hole tube, so that the conical surface at the end of the locking rod is in contact with the inclined surface of the main support block and the inclined surface of the auxiliary support block. The locking rod is then screwed in, and as the locking rod continues to be screwed in, the conical surface at the end of the locking rod pushes the main support block and the auxiliary support block to move in opposite directions until the auxiliary support beam contacts the top wall of the movable groove, and the main support block abuts against the step in the mounting hole. In this way, the auxiliary support beam can be supported by the main support block and the locking rod, so that the auxiliary support beam can strengthen the support for the position of the locking beam relative to the gate groove. This can not only improve the support for the gate and reduce existing safety hazards, but also share the load-bearing capacity of the locking beam and enhance the supporting strength of the locking beam.

DETAILED DESCRIPTION

[0049] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0050] like Figure 1 As shown, this embodiment provides a hydropower station gate locking beam flexible automatic throw-in and throw-out device, including a locking beam 2 and an automatic throw-in and throw-out unit, the two sides of the locking beam 2 are respectively slidably matched with the platforms 100 on both sides of the gate 3 slot. In this embodiment, slideways 1 are provided on the platforms 100 on both sides of the gate 3 slot, and the two sides of the locking beam 2 can respectively slidably match with the two slideways 1 on the platform 100.

[0051] The automatic throwing and withdrawing unit includes a connecting member and a driving member that drives the connecting member to move horizontally back and forth. The connecting member is connected to the locking beam 2. The driving member can drive the locking beam 2 to move below the gate 3 or away from the gate 3 through the connecting member. Specifically: Figure 1 and Figure 2 As shown, in this embodiment, the driving member includes a motor 5 and a lead screw, and a vertical plate 502 and a base 501 are installed on the platform 100. The vertical plate 502 is vertically connected to the base 501. In this embodiment, the vertical plate 502 and the base 501 are bolted or integrally formed, and the motor 5 is installed on the base 501;

[0052] One end of the lead screw is connected to the output shaft of the motor 5 through a coupling, and the other end of the lead screw is rotatably matched with the vertical plate 502 through a bearing. The connecting piece is threadedly matched with the lead screw, and the connecting piece is slidably matched with the base 501, such as Figure 1As shown, in this embodiment, the connecting parts include a left connecting rod 7, a right connecting rod 8 and a cross slider 11. One end of the left connecting rod 7 and one end of the right connecting rod 8 are respectively connected to the two ends of the cross slider 11 as a whole, and the other end of the left connecting rod 7 and the other end of the right connecting rod 8 are respectively threaded, welded or bolted to the left and right parts of the locking beam 2, the cross slider 11 is threadedly matched with the lead screw, and the cross slider 11 is slidably matched with the base 501, and the driving member is arranged parallel to the left connecting rod 7 and the right connecting rod 8.

[0053] Combination Figure 2 and Figure 3 As shown, a threaded through hole is provided in the middle of the cross slider 11, and the cross slider 11 is threadedly connected to the lead screw through the threaded through hole, and a track 16 is connected to the top of the base 501, and pulleys 17 are rotatably connected to both sides of the bottom of the cross slider 11, and the two pulleys 17 slide along the two sides of the track 16. In this way, when the lead screw is rotating, the cross slider 11 can reciprocate forward and backward along the track 16. In this embodiment, the cooperation of the track 16 and the pulley 17 can reduce the friction of the cross slider 11 during the movement, and can also support the cross slider 11.

[0054] like Figure 1 As shown, a left slide 9 and a right slide 10 are also connected to the platform 100 on one side of the gate 3 slot, and the left connecting rod 7 and the right connecting rod 8 pass through the left slide 9 and the right slide 10 respectively. In this embodiment, the left slide 9 and the right slide 10 both include a hollow cylinder and connecting plates on both sides of the cylinder, and the connecting plates are fixed to the top of the platform 100 by bolts. In this embodiment, the inner wall of the cylinder is smooth, and the left connecting rod 7 and the right connecting rod 8 pass through the cylinder of the left slide 9 and the right slide 10 respectively and can slide axially along the cylinder.

[0055] In another embodiment, a buffer pad 4 is connected to the top of the locking beam 2 to mitigate the impact force when the locking beam 2 contacts the gate 3 and protect the gate 3 and the locking beam 2 from damage.

[0056] In another embodiment, in combination Figure 1 and Figure 4 As shown, the driving component also includes a driver 6, which is electrically connected to the motor 5. In this embodiment, the motor 5 is a stepper motor 5. The driver 6 is used to control the output of the stepper motor 5. The stepper motor 5 is connected to the driver 6 via a signal line, and the signal output end of the driver 6 is connected to the signal input end of the stepper motor 5.

[0057] like Figure 1As shown, a retracted-in-place switch 13 and an inserted-in-place switch 14 are connected to the lead screw, and the position where the connecting piece is connected to the lead screw is between the retracted-in-place switch 13 and the inserted-in-place switch 14. Specifically: in this embodiment, the horizontal slide block 11 is located between the retracted-in-place switch 13 and the inserted-in-place switch 14. After the gate 3 is lifted, the locking beam 2 is located directly below the lifted gate 3, which means that the locking beam 2 is in place, and at this time, the horizontal slide block 11 is in contact with the inserted-in-place switch 14; when the gate 3 is lowered, the locking beam 2 is located away from the gate 3, which means that the locking beam 2 is retracted into place, and at this time, the horizontal slide block 11 is in contact with the retracted-in-place switch 13.

[0058] The retracted position switch 13 and the inserted position switch 14 are both electrically connected to the driver 6. In this embodiment, the retracted position switch 13 and the inserted position switch 14 both include a limit block and a trigger. The limit block is connected to the lead screw, and the trigger is installed on the limit block. The signal output end of the trigger is connected to the signal input end of the driver 6. In this embodiment, the retracted position switch 13 and the inserted position switch 14 are provided to limit the locking beam 2 when it is retracted and inserted. When the locking beam 2 touches the trigger, the in-position signal is sent to the driver 6, and the driver 6 controls the operation of the stepping motor 5 to stop driving.

[0059] In another embodiment, in combination Figure 1 , Figure 2 and Figure 4 As shown, a fuzzy controller is provided in the driver 6, and a position sensor 15 is installed on the side of the vertical plate 502 facing the retracted position switch 13. The position sensor 15 detects the position of the connecting piece in real time, that is, detects the position of the locking beam 2; the position sensor 15 is electrically connected to the fuzzy controller, and the fuzzy controller is used to receive the position signal sent by the position sensor 15 so that the driver 6 can adjust the output of the motor 5 in real time.

[0060] Combination Figure 4 and Figure 5As shown, the fuzzy controller receives the precise input quantity (i.e., the precise position signal) output from the position sensor 15, and obtains the position deviation and the position deviation change rate as the input variables of the fuzzy controller by subtracting the precise input quantity from the expected value, and converts the input variables into fuzzy quantities, determines the fuzzy language value of the input variables and the corresponding membership function, and performs reasoning according to the fuzzy rule base established in the fuzzy controller to calculate the fuzzy output corresponding to the fuzzy input, obtains the precise output value according to the defuzzification, and adjusts the output of the stepper motor 5 in real time, and reduces the output of the motor 5 in advance when the locking beam 2 is close to the insertion or retraction position to prevent overshoot, effectively reduces the impact force when the horizontal slide block 11 collides with the insertion position switch 14 and the retraction position switch 13, and reduces the inertia of the locking beam 2, so that the locking beam 2 can smoothly reach the specified position, which can also reduce the wear between the components in the entire device and extend the service life; when the locking beam 2 is far from the insertion or retraction position, the output of the motor 5 is increased to shorten the action time of the locking beam 2. This embodiment uses fuzzy control to make the process of inserting or retracting the locking beam 2 smoother.

[0061] The rule base established in this embodiment is as follows: when the position deviation is large, if the position deviation change rate is fast, the control amount can be maintained stable.

[0062] If the rate of change is fast, slow, or slow, the control amount needs to be increased to approach the target faster; when the position deviation is large, the control amount is reduced when the position deviation change rate is fast to avoid overshoot, and the control amount is maintained to ensure stability when the change rate is fast.

[0063] If the position deviation changes at a low or slow rate, the control amount needs to be increased to speed up the approach to the target; when the position deviation is small and the position deviation changes at a high or fast rate, the control amount needs to be reduced to avoid overshoot.

[0064] When the position deviation rate of change is slow, maintain the control amount to ensure stability. When the position deviation rate of change is slow, increase the control amount to speed up the approach to the target; when the position deviation is small, the position deviation rate of change is fast, fast or slow, and the control amount needs to be reduced to avoid overshoot. When the position deviation rate of change is slow, maintain the control amount to ensure reaching the target.

[0065] In the specific implementation of the present invention: when the locking beam 2 needs to be invested or retracted, the output signal of the driver 6 controls the motor 5, the screw on the stepper motor 5 rotates to drive the horizontal slider 11 to move straightly along the track 16 on the base 501, and the horizontal slider 11 drives the locking beam 2 to move through the left connecting rod 7 and the right connecting rod 8 connected thereto, so that it moves straightly on the slide 1 on the platform 100 on both sides of the gate 3 slot. When the retraction position switch 13 and the investment position switch 14 are touched, the stepper motor 5 stops outputting and the locking beam 2 stops moving, thereby realizing the automatic investment and withdrawal of the locking beam 2.

[0066] During the movement, the position sensor 15 detects the position of the horizontal slide 11, i.e., the locking beam 2, in real time, and transmits the position signal to the driver 6. The driver 6 obtains the position deviation and position deviation change rate of the locking beam 2, converts the precise input quantity into a fuzzy quantity, and determines the fuzzy language and membership function of the fuzzy quantity. When the position deviation of the locking beam 2 from the retracted position switch 13 or the inserted position switch 14 is large, and the position deviation change rate is slow, then it is necessary to increase the control amount, increase the output of the stepping motor 5, and shorten the time of insertion or retraction (exit);

[0067] When the position deviation of the locking beam 2 from the retracted into position switch 13 or the inserted into position switch 14 is small and the position deviation changes at a fast rate, it is necessary to reduce the control amount and gradually reduce the output of the stepping motor 5 to prevent a violent collision.

[0068] According to the above principle, the fuzzy control rule table is determined, the fuzzy control quantity is calculated, and the precise control quantity is obtained through anti-fuzzy transformation. The control quantity controls the output of the stepping motor 5 in real time to realize the smooth automatic throwing and retreating of the locking beam 2 of the hydropower station. At the same time, the double protection of the locking beam 2 retracting into place switch 13, the locking beam 2 throwing into place switch 14 and the position sensor 15 makes the automatic throwing and retreating device safer.

[0069] The present invention supports remote control function, and realizes remote operation and smooth insertion and retraction of the locking beam 2 through the connection between the driver 6 and the signal line, which facilitates management and monitoring, improves the automation management level of the system, and ensures the safe operation of the gate 3.

[0070] like Figure 6 As shown, in another embodiment, the difference from the above embodiment is that a hydropower station gate locking beam flexible automatic throwing and retracting device in this embodiment also includes a locking rod 22.

[0071] The first slide plate 101 and the second slide plate 102 are connected to both sides of the bottom of the locking beam 2, and the slide 1 is located between the first slide plate 101 and the second slide plate 102. The locking beam 2 is horizontally slidably matched with the slide 1 through the first slide plate 101 and the second slide plate 102, that is, the locking beam 2 can be slidably matched with the slide 1 under the action of the first slide plate 101 and the second slide plate 102.

[0072] The first slide 101 and the second slide 102 are provided with sockets that are arranged opposite to each other; a through hole is provided on the slide 1 at the position opposite to the locking beam 2 when it is put into place. In this embodiment, when the locking beam 2 is put into place, it moves to be directly below the gate 3, and when the locking beam 2 is put into place, the sockets on the first slide 101 and the second slide 102 are aligned and overlapped with the through holes on the slide 1. At this time, the locking rod 22 can pass through the sockets on the first slide 101, the through holes on the slide 1, and the sockets on the second slide 102 in sequence, so that the insertion position of the locking beam 2 can be accurately positioned and limited, so that the locking beam 2 can provide stable and reliable support for the gate 3, and is not easily caused by accidental touch or other situations to cause the locking beam 2 to be retracted prematurely, thereby ensuring the reliability of the locking beam 2 supporting the gate 3.

[0073] In another embodiment, Figure 6 and Figure 7 As shown, in this embodiment, a flexible automatic throwing and retracting device for the locking beam of a hydropower station gate also includes an auxiliary support beam 18, a movable groove 201 is opened at the bottom of the locking beam 2, and the auxiliary support beam 18 is located in the movable groove 201. In this embodiment, the movable groove 201 is a T-shaped groove structure, and the top of the auxiliary support beam 18 is located in the movable groove 201, and the shape of the auxiliary support beam 18 is adapted to the shape of the movable groove 201. In this embodiment, the top edge of the auxiliary support beam 18 is provided with a protruding block 180 protruding outward, and the protrusion 180 on the edge of the auxiliary support beam 18 can be confined in the movable groove 201 and will not fall out of the movable groove 201.

[0074] Under the action of gravity, there is a distance between the top end of the auxiliary support beam 18 and the top wall of the moving groove 201, so that the auxiliary support beam 18 has space to move upward.

[0075] Mounting holes 20 are provided at the top of the platforms 100 on both sides of the gate 3 slot and at the position where the locking beam 2 is put into place. A main support block 19 is provided in the mounting hole 20. In this embodiment, the mounting hole 20 is a stepped hole, so that there is a step in the mounting hole 20. A spring 21 is connected between the main support block 19 and the bottom of the mounting hole 20. Under the action of the spring 21, the top of the main support block 19 is located above the mounting hole 20, and the bottom of the main support block 19 is located above the step in the mounting hole 20.

[0076] In this embodiment, when the locking beam 2 is put into place, the auxiliary support block 181 at the bottom of the auxiliary support beam 18 is arranged vertically opposite to the main support block 19; auxiliary support blocks 181 are connected to both sides of the bottom of the auxiliary support beam 18, and the ends of the auxiliary support blocks 181 and the main support blocks 19 facing each other are provided with inclined surfaces, and the inclined surfaces of the auxiliary support blocks 181 and the inclined surfaces on the main support blocks 19 form a flared structure opening in the direction of the slideway 1 on the same side.

[0077] The end of the locking rod 22 facing the auxiliary support block 181 is provided with two conical surfaces that can respectively abut and cooperate with the inclined surfaces of the main support block 19 and the auxiliary support block 181, so that the locking rod 22 forms a conical structure. The conical surface of the locking rod 22 abuts against the inclined surfaces of the auxiliary support block 181 and the main support block 19 and pushes the top of the auxiliary support beam 18 to abut against the top wall of the movable groove 201, while the bottom of the main support block 19 also abuts against the step in the mounting hole 20. This can be achieved by designing the distance between the top wall of the movable groove 201 and the top of the auxiliary support beam 18 and the distance between the main support block 19 and the step in the mounting hole 20. For example, the distance between the top wall of the movable groove 201 and the top of the auxiliary support beam 18 is equal to the distance between the bottom of the main support block 19 and the step in the mounting hole 20 when the spring 21 is in the natural state, thereby enabling the main support block 19 to effectively support the auxiliary support beam 18.

[0078] The locking rod 22 is threadedly connected to at least one of the two sockets. In this embodiment, the locking rod 22 is threadedly connected to the socket on the first slide 101 and the socket on the second slide 102 as an example. By screwing in the locking rod 22, the locking rod 22 can be moved toward the auxiliary support block 181 and the main support block 19, thereby pushing the auxiliary support block 181 and the main support block 19 to move in opposite directions. In this way, when the locking beam 2 is put into place, by screwing the locking rod 22 into the socket, the end conical surface of the locking rod 22 is brought into contact with the inclined surfaces on the auxiliary support block 181 and the main support block 19, and the auxiliary support block 181 is pushed to move upward until the top of the auxiliary support beam 18 abuts against the top wall of the movable groove 201, and at the same time, the main support block 19 is pushed downward until the bottom of the main support block 19 abuts against the step in the mounting hole 20.

[0079] In this way, the auxiliary support beam 18, under the support of the locking rod 22 and the main support block 19, effectively enhances the support for the locking beam 2, thereby realizing the dual support effect of the locking beam 2 and the auxiliary support beam 18 on the gate 3. Moreover, since the auxiliary support beam 18 is located directly above the groove of the gate 3, it can enhance the supporting strength of the position where the locking beam 2 is used to support the gate 3, thereby reducing the load-bearing pressure of the locking beam 2 and thereby increasing the service life of the locking beam 2.

[0080] In another embodiment, Figure 8 As shown, the top end of the locking beam 2 is provided with an inclined surface inclined toward the gate 3 , and one or more limiting grooves 202 are opened on the inclined surface, and the gate 3 can be inserted into the limiting grooves 202 .

[0081] After the lifting device lifts the gate 3, it needs to wait for a certain period of time for the locking beam 2 to move to the bottom of the gate 3. If the lifting device fails and the lifting height of the gate 3 does not meet the requirements, the gate 3 will be lifted shorter. In this embodiment, since the top of the locking beam 2 is an inclined surface inclined toward the gate 3, when the locking beam 2 moves to the gate 3, the inclined surface of the locking beam 2 can push the gate 3 upward while the locking beam 2 continues to move forward, so that the gate 3 is moved to the corresponding limit groove 202 for locking. At this time, the locking beam 2 can support the gate 3.

[0082] In addition, this embodiment has lower requirements on the accuracy of the supporting position of the locking beam 2 for the gate 3. It only requires that the locking beam 2 is located below the gate 3, and the lifting equipment allows the gate 3 to fall to the inclined surface of the locking beam 2. The lifting equipment allows the gate 3 to retain a shorter vertical displacement space. In this way, by driving the locking beam 2 forward again, the inclined surface of the locking beam 2 will lift the gate 3 until it is opposite to the limit groove 202 and is located in the limit groove 202.

[0083] The setting of the limit groove 202 in this solution can provide stable support and limitation for the gate 3. At the same time, the setting of multiple limit grooves 202 can change the support height of the gate 3. At the same time, it is convenient to drive the locking beam 2 to continue to move forward so that the gate 3 can be stuck in the nearest limit groove 202 for locking and support.
