TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic engineering, in particular to a hoist for realizing automatic layered water taking of a stoplog gate and a control system and a control method thereof. BACKGROUND

[0002] In a water supply project, the stoplog gate is a gate suitable for layered water taking. A plurality of separate gates are placed in the gate slot one by one and are placed side by side to form a planar water retaining structure. When water at different heights is needed, the stoplog gate can be stacked one by one in the vertical direction to form a gate with an increased total height. When taking water, the water level can be controlled according to the number of opened gates to realize layered water taking.

[0003] However, the layered water taking at the stoplog gate is currently mainly realized by manually opening the gate. This operation method not only requires the operator to interpret the water level for 24 hours a day and to perform relevant operations in combination with the specific water level, but also requires multiple people to cooperate to complete the operation due to the large weight of the gate. Therefore, it not only leads to a large working intensity of the operator, but also leads to a large number of required operators. SUMMARY

[0004] In order to solve at least one of the problems of a large working intensity of the operator and a large number of required operators caused by the layered water taking of the traditional stoplog gate, according to one aspect of the present application, a hoist for realizing automatic layered water taking of a stoplog gate is provided.

[0005] The hoist for realizing automatic layered water taking of the stoplog gate includes a centralized gate library provided on a gate pier and used for respectively storing sub-gates constituting the stoplog gate; a first movement unit fixed relative to the gate pier; and a hoist device provided on the first movement unit; wherein the first movement unit is configured to drive the hoist device to reciprocate between a total gate slot of the gate pier for installing the stoplog gate and the centralized gate library provided on the gate pier; and the hoist device is configured to grab the sub-gate.

[0006] Therefore, the operator can grab the sub-gate by the hoist device and drive the hoist device by the first movement unit to transport the grabbed sub-gate from the centralized gate library to the total gate slot or from the total gate slot to the centralized gate library. Thus, the layered water taking according to the requirement can be realized while reducing the working intensity of the operator and the number of operators.

[0007] According to another aspect of the present application, a control system for the hoist is provided.

[0008] The control system for the hoist is used for the hoist for automatically taking water by layer of the aforementioned hoist, and comprises a control module, one of a first positioning device and a first detection device corresponding to the gate slot, and the other of the first positioning device and the first detection device arranged on the pier; and the first detection device is arranged to send a detection signal to the control module when the first positioning device is detected; and the control module is arranged to control the hoist to take and place the sub-gate in the corresponding gate slot according to the received detection signal.

[0009] Therefore, the control module, the first positioning device and the first detection device can assist the first movement unit to automatically drive the lifting unit and the hydraulic grab beam to the position of the corresponding gate slot, so as to assist the hoist to realize automation.

[0010] According to another aspect of the present application, a control method of a control system for a hoist is provided.

[0011] The control method of the control system for the hoist comprises the following steps:

[0012] S31: The control module controls the first movement unit to transport the hoist to the total gate slot according to the detection signal sent by the second detection device according to the water level signal;

[0013] S32: The control module controls the hoist to grab the sub-gate above the water level in the total gate slot according to the height detection device;

[0014] S33: The control module controls the first movement unit to transport the hoist to the corresponding gate slot according to the detection signal sent by the first detection device, and controls the hoist to place the grabbed sub-gate into the corresponding gate slot;

[0015] S34: Steps S31 to S33 are repeated until the water level at the sub-gate at the top of the total gate slot matches the water level signal; or the following steps are included:

[0016] S31`: The control module controls the first movement unit to transport the hoist to the corresponding gate slot according to the detection signal sent by the first detection device according to the water level signal;

[0017] S32`: The control module controls the hoist to grab the sub-gate in the corresponding gate slot;

[0018] S33`: The control module controls the first movement unit to transport the hoist to the total gate slot according to the detection signal sent by the second detection device, and controls the hoist to place the grabbed sub-gate into the total gate slot;

[0019] S34`: Repeat steps S31` to S33` until the water level height at the sub-gate at the top of the total gate slot matches the collection water level height.

[0020] Therefore, the control module, the first positioning device, the first detection device, the auxiliary first movement unit, the height detection device, the second positioning device and the second detection device can drive the opening and closing device to the position corresponding to the sub-gate slot, so as to assist the hoist to realize automation, thereby solving the problems of low intelligent degree and difficulty in realizing automatic operation and intelligent regulation of water flow of the traditional hoist.

[0045] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0046] Figures 1 to 21 A hoist for realizing automatic stratified water taking of a stoplog gate 50 according to an embodiment of the present application is schematically shown.

[0047] As Figure 1 shown, the hoist for realizing automatic stratified water taking of the stoplog gate 50 comprises a centralized gate warehouse 40 arranged on a gate pier 100 and used for respectively storing sub-gates 51 constituting the stoplog gate 50; a first movement unit 1 fixedly arranged relative to the gate pier 100; and a hoist device 2 arranged on the first movement unit 1; wherein the first movement unit 1 is arranged to be capable of driving the hoist device 2 to reciprocate (i.e. along an X direction) between a total gate slot 101 of the gate pier 100 for mounting the stoplog gate 50 and the centralized gate warehouse 40 arranged on the gate pier 100; and the hoist device 2 is arranged to be capable of grabbing the sub-gate 51. Generally, a water stop device 512 is arranged between adjacent sub-gates 51 to prevent water leakage between the adjacent sub-gates 51, and each sub-gate 51 is arranged with a pin hole 511 matched with a hydraulic grab beam 2A to facilitate the hoist device 2 to hoist the sub-gate 51.

[0048] As one of the embodiments of the first movement unit 1, continuing to refer to Figure 1 shown, the first movement unit 1 comprises a walking track 11 fixedly arranged relative to the gate pier 100, the walking track 11 being arranged along the X direction; and a walking mechanism 12 capable of moving along the extension direction of the walking track 11. Exemplarily, the walking mechanism 12 comprises a walking wheel 122 matched with the walking track 11, and a first rotating motor 121 capable of driving the walking wheel 122 to rotate on the walking track 11. Preferably, in order to facilitate the hoist device 2 to be arranged on the first movement unit 1, the first movement unit 1 further comprises a rack 13, the first rotating motor 121 and the hoist device 2 are fixedly arranged relative to the rack 13, and the walking wheel 122 is pivotally arranged on the rack 13.

[0049] As one of the embodiments of the hoist device 2, the hoist device 2 can adopt a hoist device 2 commonly used in hoists.

[0050] When using this hoist, the operator can grab the sub-gate 51 through the hoisting device 2, and drive the hoisting device 2 through the first motion unit 1 to transport the grabbed sub-gate 51 from the central gate storage 40 to the main gate slot 101, or from the main gate slot 101 to the central gate storage 40. In this way, the operator can achieve stratified water intake according to demand while reducing the workload of the operator and the number of operators.

[0051] In some embodiments, such as Figure 1 As shown, the centralized gate storage 40 is provided with at least two gate slots 410 for accommodating individual sub-gates 51. The centralized gate storage 40 is configured such that, when it is installed on the gate pier 100, all gate slots 410 are arranged along the direction of movement (i.e., the X direction) of the opening and closing device 2 driven by the first motion unit 1. This facilitates the first motion unit 1 driving the opening and closing device 2 to place different sub-gates 51 into different gate slots 410, enabling the classified placement of the sub-gates 51 and allowing the hoist to automatically retrieve and place the sub-gates 51 according to the actual water intake scheme. Specifically, the number of gate slots 410 is equal to the number of sub-gates 51 constituting the stacked beam gate 50. This ensures that every sub-gate 51 retrieved from the main gate slot 101 has a gate slot 410 to store it.

[0052] In some preferred embodiments, the centralized gatehouse 40 is detachably mounted on the gate pier 100, and the centralized gatehouse 40 is provided with a locking structure 42. The centralized gatehouse 40 has an unfolded state when locked with the locking structure 42, and a folded state when unlocked with the locking structure 42. For example, the centralized gatehouse 40 includes a gatehouse body 41 and a locking structure 42; the gatehouse body 41 has an unfolded state when locked with the locking structure 42 (e.g., ...). Figure 2 (as shown), and the folded state when the locking structure 42 unlocks it (as shown). Figure 4 (As shown). Therefore, when the sub-gate 51 needs to be stored in the central gate 40, the central gate can be kept in an unfolded state by locking structure 42; when the central gate 40 needs to be transported, the central gate 40 can be folded by unlocking locking structure 42, thereby reducing the difficulty of transporting the central gate 40 by reducing its volume.

[0053] As one embodiment of the centralized gatehouse 40, such as Figures 2 to 4 As shown, the centralized access gate 40 includes a bottom support 411 and side supports 412, one end of which is pivotally mounted on opposite sides of the bottom support 411 about a first pivot axis 413, i.e., at least two sets of side supports 412 are arranged side by side; the side supports 412 have an unfolded state when locked to the bottom support 411 by the locking structure 42 (e.g., Figure 2 (as shown), and the folded state when the locking structure 42 unlocks it from the bottom bracket 411 (as shown).Figure 4 As shown in FIG. 1, the side support 412 is provided with a locking structure 42, and the locking structure 42 is provided with a locking mechanism 421 and a locking handle 422. As shown in FIG. 1, when the side support 412 is in the unfolded state, the locking mechanism 421 is in the locked state, and the locking handle 422 is in the locked state. When the side support 412 is in the folded state, the locking mechanism 421 is in the unlocked state, and the locking handle 422 is in the unlocked state. Thus, when it is necessary to store the sub-gates 51 in the centralized gate library 40, the side support 412 can be kept in the unfolded state by locking the locking structure 42; when it is necessary to transport the centralized gate library 40, the side support 412 can be kept in the folded state by unlocking the locking structure 42, and since the side support 412 can also be pivoted relative to the bottom support 411 about the first pivot shaft 413, the folding state of the centralized gate library can be further improved, so that the difficulty of transporting the centralized gate library 40 can be reduced by reducing the volume of the centralized gate library 40.

[0054] As one of the embodiments in which the side support 412 has the unfolded state and the folded state, with continued reference to FIG. 1, Figures 1 to 4 As shown in FIG. 1, the side support 412 includes at least two guide rods 4121 and at least one support rod 4122 pivotally connected with all the guide rods 4121 about a second pivot shaft 4123, the guide rods 4121 are pivotally arranged relative to the bottom support 411 about the first pivot shaft 413, and the second pivot shaft 4123 is parallel to the first pivot shaft 413, and the adjacent two guide rods 4121 form a containing position for containing one sub-gate 51. Thus, the side support 412 can be switched between the unfolded state and the folded state by adjusting the angle at which the support rod 4122 is pivoted relative to the guide rods 4121 about the second pivot shaft 4123, and the sub-gates 51 can be classified and managed. In particular, all the guide rods 4121 are arranged in the direction in which the first movement unit 1 drives the opening and closing device 2 to move when the centralized gate library 40 is arranged on the pier 100. Thus, when the side support 412 is in the folded state by adjusting the angle at which the support rod 4122 is pivoted relative to the guide rods 4121 about the second pivot shaft 4123, the adjacent guide rods 4121 can be arranged side by side and abut against each other, so that the structure of the side support 412 is compact enough when the side support 412 is in the folded state. Preferably, the containing position for containing one sub-gate 51 is formed between the adjacent two guide rods 4121 in the side support 412, and the containing positions of the two side supports 412 and the bottom support 411 together form the gate separating groove 410. Thus, the space between the guide rods 4121 forms the space for containing the sub-gates 51, which can simplify the structure of the centralized gate library and facilitate the manufacture and installation of the centralized gate library. Preferably, in order to facilitate the sub-gates 51 to be smoothly put into the gate separating groove 410, a guide segment 41211 is further arranged at the opening of the gate separating groove 410, and in particular, the guide segment 41211 (such as a chamfer or an inclined surface) is arranged on the side of the guide rod 4121 away from the bottom support 411. Generally, the chamfer and the inclined surface are arranged on the sides of the adjacent guide rods 4121 facing each other.

[0055] As one of the embodiments of the locking structure 42, as shown in FIG. 1, Figures 2 to 4As shown, the locking structure 42 comprises at least two inclined support rods 421, which are not parallel to the guide rod 4121, and one end of the at least two inclined support rods 421 is connected to the bottom support 411 and the other end is connected to the side support 412, and the connection positions on at least one of the bottom support 411 and the side support 412 are different, and the connection with at least one of the bottom support 411 and the side support 412 is detachable. Thus, the side support 412 can be locked relative to the bottom support 411 by connecting the at least two inclined support rods 421 to the bottom support 411 and the side support 412; when it is needed to unlock the side support 412 from the bottom support 411, it is only needed to detach the inclined support rods 421 from the bottom support 411 or the side support 412, which is convenient for installation and detachment. Preferably, the at least two inclined support rods 421 are not parallel when the side support 412 is in the unfolded state. Thus, it can be ensured that when the inclined support rods 421 connect the side support 412 to the bottom support 411, the side support 412 is locked and in the unfolded state. Preferably, the connection positions of the at least two inclined support rods 421 with the side support 412 are respectively located near the two ends of the side support 412. Thus, it can be ensured that when the inclined support rods 421 connect the side support 412 to the bottom support 411, the side support 412 is locked and in the unfolded state. In particular, the inclined support rods 421 are pivotably connected to the bottom support 411 through a third pivot shaft 422 and to the side support 412 through a fourth pivot shaft 423, and the third pivot shaft 422 and the fourth pivot shaft 423 are parallel to the first pivot shaft 413. Thus, when the inclined support rods 421 are pivotably connected to the bottom support 411 through the third pivot shaft 422, when it is needed to unlock the centralized door bank 40, the inclined support rods 421 can be detached from the side support 412; when the inclined support rods 421 are pivotably connected to the side support 412 through the fourth pivot shaft 423, when it is needed to unlock the centralized door bank 40, the inclined support rods 421 can be detached from the bottom support 411, so that not only the side support 412 can form a folded state, but also the inclined support rods 421 can make the entire centralized door bank 40 fold more compactly by pivoting relative to the bottom support 411 (or the side support 412).

[0056] As a preferred embodiment of the opening and closing device 2, as shown in Figures 5 to 15As shown, the opening and closing device 2 comprises a lifting unit 200 arranged on the first movement unit 1; and a hydraulic grab beam 2A arranged on the lifting unit 200 for taking and placing the sub gate 51; wherein the first movement unit 1 is arranged to be able to drive the lifting unit 200 to reciprocate between the total gate slot 101 of the gate pier 100 for mounting the stoplog gate 50 and the centralized gate library 40 arranged on the gate pier 100; the lifting unit 200 is arranged to be able to drive the hydraulic grab beam 2A to rise or fall; the hydraulic grab beam 2A is arranged to be able to grab or release the sub gate 51. Thus, when the first movement unit 1 drives the lifting unit 200 to move to the position, the hydraulic grab beam 2A can be driven by the lifting unit 200 to make lifting movement, so as to take and place the sub gate 51 by the hydraulic grab beam 2A. Generally, the lower part of the hydraulic grab beam 2A is provided with a positioning and pinning device 37 for automatically grabbing the sub gate 51.

[0057] As one of the embodiments of the lifting unit 200, the lifting unit 200 can adopt the lifting unit 200 commonly used in the hoist.

[0058] As one of the embodiments of the hydraulic grab beam 2A, the lifting unit 200 can adopt the hydraulic grab beam 2A commonly used in the hoist.

[0059] Due to the different functions and opening and closing modes of the trash rack, the maintenance gate, the working gate and other hydraulic metal structures, and the different widths of the gate slot (or the trash rack slot 102) and the distances from the lifting point of the to-be-lifted object to the supporting surface, different hydraulic grab beams 2A need to be configured to adapt to the different gate slots (or trash rack slots 102) and the gravity center positions of the opening and closing objects when the hydraulic grab beam 2A is used to open and close these hydraulic metal structures, which not only causes the problem of high equipment cost due to the large number of hydraulic grab beams 2A, but also causes the problems of safety hazards and inconvenience in use due to the frequent disconnection and connection of the power supply devices of the hydraulic grab beams 2A and different hydraulic grab beams 2A. At the same time, the problems of water leakage and electric leakage caused by the poor sealing of the water-tight joints during the disconnection and connection conversion process often occur. In addition, for some small-width gates (or trash racks) with the lifting point arranged on the side beam, the winch-type hoist cannot be matched with double lifting points, and only a hydraulic grab beam 2A with an upper single lifting point 21 and a lower double lifting point can be used. The upper single lifting point 21 of the hydraulic grab beam 2A is matched with the single lifting point 21 hoist, and the lower double lifting point of the hydraulic grab beam 2A is matched with the double lifting point of the gate (or trash rack). If the hydraulic grab beam 2A with this structure is to be used to open and close gates (or trash racks) of different sizes, the matching method and the distance adjustment between the lifting point of the to-be-lifted object and the supporting surface in the water flow direction are very critical to avoid the problem that the hydraulic grab beam 2A cannot work stably due to the imbalance of the gravity center caused by the structure of the upper single lifting point 21. Moreover, if the hydraulic grab beam 2A with the upper single lifting point 21 is used to open and close the gate (or trash rack) with the double lifting point, the distance between the lifting point of the to-be-lifted object and the supporting surface in the water flow direction needs to be adjusted to the distance between the upper single lifting point 21 of the hydraulic grab beam 2A and the supporting surface, which is not only inconvenient, but also causes the problem that the hydraulic grab beam 2A cannot work stably due to the imbalance of the gravity center. Figure 1 and Figure 2As shown, in most projects, the width B of the gate slot is greater than the width B' of the trash rack slot 102; the distance Y1 from the opening and closing center to the gate slot is different from the distance Y1' from the opening and closing center of the trash rack to the center of the supporting surface to the trash rack slot 102, according to the traditional method, two different hydraulic grab beams 2A need to be set to meet the opening and closing of the gate and the trash rack, that is, the aforementioned problems of high equipment cost caused by too many hydraulic grab beams 2A, safety hazards and inconvenience caused by frequent disconnection and connection of the power supply device of the hydraulic grab beam 2A and different hydraulic grab beams 2A, and water leakage and electric leakage caused by poor sealing of the water-tight joint during the disconnection and connection conversion process still exist. In order to solve the above problems, as shown in Figures 10 to 18 The application provides a hydraulic grab beam 2A.

[0060] As shown in Figure 10 The hydraulic grab beam 2A comprises a grab beam body 20, a hydraulic pump station 22 and a first balancing block 23; wherein a single lifting point 21 is fixedly arranged on the upper part of the grab beam body 20 (because the size of the gate slot (or the trash rack slot 102) in the direction perpendicular to the water flow direction (the length direction of the hydraulic grab beam 2A (the grab beam body 20)) is small, if a double-lifting-point winch-type hoist is arranged, the lifting mechanism of the hoist cannot avoid the interference between the steel wire rope and the gate slot (or the trash rack slot 102) during the working process, therefore, the inventor conceives a hydraulic grab beam 2A with a single lifting point 21 on the upper part and double lifting points on the lower part, which is used in cooperation with the hoist. The single lifting point 21 is arranged on the upper part of the grab beam body 20 and is matched with the movable pulley set of the winch-type hoist, and the double lifting points are matched with the lifting points of the gate or the trash rack, the grab beam body 20 is provided with a pin passing device 37, such as a hydraulic pin passing device, which is pushed or pulled by the hydraulic pressure, generally, the single lifting point 21 on the upper part is located at the center of gravity of the grab beam body in the length direction y and the width direction x of the grab beam body 20; the hydraulic pump station 22 is used to provide power for the pin passing device 37 on the hydraulic grab beam 2A, the pin passing device 37 is used to detachably connect the lower lifting point 26 of the grab beam body 20 and the upper lifting point of the target object to be opened and closed, the connection mode can adopt the commonly used connection mode in the prior art, and the hydraulic pump station 22 can adopt the commonly used hydraulic pump station 22 in the prior art, which is not limited in the application; because the length of the general grab beam body 20 is much greater than its width, therefore, the hydraulic pump station 22 is generally arranged on one side of the upper part of the grab beam body 20 in the length direction of the grab beam body 20; the first balancing block 23 is arranged on the grab beam body and can balance the eccentric moment of the hydraulic pump station 22, the first balancing block 23 balances the eccentric moment of the hydraulic pump station 22, that is, the first balancing block 23 can balance the eccentric moment of the grab beam body 20 provided with the hydraulic pump station 22.

[0061] For example, the first counterbalance block 23 capable of balancing the eccentric moment of the hydraulic pump station 22 is implemented as follows: the weight of the first counterbalance block 23 on the side away from the hydraulic pump station 22 along the length direction of the grab beam body 20 is greater than that on the side close to the hydraulic pump station 22, for example, the volume V1 of the first counterbalance block 23 on the side away from the hydraulic pump station 22 along the length direction of the grab beam body 20 is set to be greater than the volume V2 of the first counterbalance block 23 on the side close to the hydraulic pump station 22, i.e. V1>V2 (as shown in Figure 11 Due to the fact that the hoisting point center A1 and the hydraulic pump station gravity center B1 do not coincide, by setting the volume V1 of the first counterbalance block 23 on the side away from the hydraulic pump station 22 along the length direction of the grab beam body 20 to be greater than the volume V2 of the first counterbalance block 23 on the side close to the hydraulic pump station 22, the combined gravity center of the hydraulic pump station 22 and the first counterbalance block 23 can be made to coincide with the hoisting point gravity center A1. In some embodiments, the first counterbalance block 23 can be made of concrete or steel (for example, steel leftover material) to reduce the production cost of the first counterbalance block 23.

[0062] Due to the fact that the first counterbalance block 23 capable of balancing the eccentric moment of the hydraulic pump station 22 is arranged on the grab beam body 20, the grab beam body 20 provided with the upper single hoisting point 21 structure can work stably to meet the requirement that the group of hydraulic grab beams 2A can stably open and close different sizes of gates and trash racks respectively.

[0063] In order to avoid the installation problems of the upper single hoisting point 21, the lower hoisting point 26, the positioning guide sleeve 31 and the pin passing device 37, and the support sliding block 36 due to the arrangement of the first counterbalance block 23, in some preferred embodiments, the first counterbalance block 23 is arranged inside the grab beam body 20, and thus the compactness of the overall structure of the hydraulic grab beam 2A can be ensured.

[0064] Due to the fact that the first counterbalance block 23 has a certain density tolerance, the first counterbalance block 23 obtained by theoretical calculation cannot completely balance the eccentric moment of the hydraulic pump station 22 in actual use, for example, after the first counterbalance block 23 is installed, there is still an eccentric moment of not more than 300 N·mm. In order to reduce the influence of the eccentric moment of the hydraulic pump station 22 that cannot be completely balanced, in some preferred embodiments, as shown in Figure 10As shown, the hydraulic grab beam 2A further comprises a fixed weight 24 arranged on the grab beam body 20, and the fixed weight 24 is arranged on the grab beam body 20 at a position corresponding to the single lifting point 21 of the upper portion. For example, the fixed weight 24 is arranged at the same position along the length direction of the grab beam body 20 as the single lifting point 21 of the upper portion. Preferably, the fixed weight 24 is not arranged on the upper portion of the grab beam body 20, nor on the lower portion of the grab beam body 20, but is arranged on the front side or the rear side of the grab beam body 20 (one of the front side and the rear side faces the water flow direction, and the other is located on the side of the grab beam body 20 away from the former, generally, the water flow direction is parallel to the width direction of the grab beam body 20), so as not to affect the installation of the single lifting point 21 of the upper portion and the lifting point or the positioning guide sleeve 31 of the lower portion. Preferably, the fixed weight 24 is arranged on both the front side and the rear side of the grab beam body 20. Further, in order to ensure the stability of the single lifting point 21 of the upper portion, the length of the fixed weight 24 along the length direction of the grab beam body 20 is greater than the length of the single lifting point 21 of the upper portion along the length direction of the grab beam body 20.

[0065] In some preferred embodiments, as Figure 12As shown, the hydraulic grab beam 2A further comprises at least two groups of guide seats 25 arranged at the lower part of the grab beam body 20; and at least one group of positioning guide sleeves 31 arranged on the guide seats 25 in a detachable manner and used in cooperation with guide pins on the target object to be opened and closed. Exemplarily, the number of guide seats 25 can be set according to the number and characteristics of the target objects to be opened and closed. For example, when a group of hydraulic grab beams 2A are required to open and close a working gate and a trash rack respectively, two groups of guide seats 25 can be arranged, i.e. a first guide seat 251 and a second guide seat 252, wherein the first guide seat 251 can correspond to the guide pin of the working gate, and the second guide seat 252 can correspond to the guide pin of the trash rack. For another example, when a group of hydraulic grab beams 2A are required to open and close a working gate, an inspection gate and a trash rack respectively, three groups of guide seats 25 can be arranged, i.e. a first guide seat 251, a second guide seat 252 and a third guide seat, wherein the first guide seat 251 can correspond to the guide pin of the working gate, the second guide seat 252 can correspond to the guide pin of the trash rack, and the third guide seat can correspond to the guide pin of the working gate. Since the size or structure between the top beam of different gates or trash racks and the upper lifting point is different, when the same group of hydraulic grab beams 2A is required to open and close different target objects (trash racks, inspection gates or working gates), different positions of the positioning guide sleeves 31 need to be arranged on the grab beam body 20, and preferably, the at least two groups of guide seats 25 are arranged along the width direction of the grab beam body 20. Since different target objects will generate different moments on the upper single lifting point 21 of the hydraulic grab beam 2A when the hydraulic grab beam 2A opens and closes the different target objects, in order to balance the different moments generated by different target objects on the upper single lifting point 21 of the hydraulic grab beam 2A, further, the hydraulic grab beam 2A further comprises a first moving unit 32 arranged on the grab beam body 20 and a second balancing block 33 arranged on the first moving unit 32, and the first moving unit 32 is arranged to drive the second balancing block 33 to move along the width direction of the grab beam body 20. Exemplarily, the first moving unit 32 comprises a first slide rod 321 arranged on the grab beam body 20 along the width direction of the grab beam body 20, and the second balancing block 33 is sleeved on the first slide rod 321. Further, in order to enable the second balancing block 33 moved to the position to be stably kept at the position, the hydraulic grab beam 2A further comprises a first locking unit 34 arranged to lock the second balancing block 33 relative to the first moving unit 32. Exemplarily, the first locking unit 34 comprises a first screw rod 341 and a first nut 342 which are adapted to each other, the first screw rod 341 is arranged on the grab beam body 20 along the width direction of the grab beam body 20, the second balancing block 33 is sleeved on the first screw rod 341, and the first nut 342 is arranged at least on both sides of the second balancing block 33. Thus, the position of the second balancing block 33 fixed relative to the first slide rod 321 can be adjusted by adjusting the position of the first nut 342 on the first screw rod 341.Specifically, the installation position of the second balancing block 33 depends on the position of the center of gravity of the object to be opened or closed. For example, when the positioning guide sleeve 31 is connected to the first guide seat 251, the second balancing block 33 is fixed to the side close to the first guide seat 251 (as shown). Figure 10 When the positioning guide sleeve 31 is connected to the second guide seat 252, the second balancing block 33 is fixed to the side close to the second guide seat 252 (as shown). Figure 13 Preferably, the first moving unit 32 is arranged on at least one end along the length direction of the grab beam body 20. Further, in order to ensure the balancing effect of the second balancing block 33, the first moving unit 32 is provided with two groups and is arranged on both ends along the length direction of the grab beam body 20.

[0066] Since the groove width corresponding to different target objects and the distance from the lifting point of the object to be lifted to the support groove surface are different, the existing same group of hydraulic grab beams 2A cannot simultaneously ensure that the single lifting point 21 of the upper part of the hydraulic grab beam 2A and the lifting point of all target objects are consistent in the direction of the water flow when the hydraulic grab beam 2A is used for different target objects. In order to solve this problem, as shown in Figure 11 and Figure 13As shown, the hydraulic grab beam 2A further comprises at least one set of lifting point offset plates 35 arranged on the grab beam body 20 for keeping the single lifting point 21 of the upper part of the grab beam body 20 consistent with the lifting point of the target object to be opened or closed in the width direction of the grab beam body 20. Preferably, when the hydraulic grab beam 2A further comprises a support slider 36 detachably arranged on the grab beam body 20; the lifting point offset plates 35 arranged on the grab beam body 20 are detachably arranged between the support slider 36 and the grab beam body 20, so as to ensure that the single lifting point 21 of the upper part of the hydraulic grab beam 2A is consistent with the size of the lifting point of the target object in the direction of the water flow, while ensuring that the support slider 36 can abut against the groove wall of the corresponding groove. Preferably, the thickness T of the lifting point offset plate 35 is set to be half of the distance difference between the opening and closing center of different target objects to be opened or closed and the corresponding groove. The lifting point offset plate 35 can be determined according to the size of the corresponding groove of the target object to be opened or closed and the size of the lifting point of the target object to be opened or closed in the width of the corresponding groove. For example, the lifting point offset plate 35 is arranged on the side of the grab beam body 20 away from the positioning guide sleeve 31 in the width direction of the grab beam body 20. Thus, when the same set of hydraulic grab beams 2A are used to open or close different target objects, the size of the single lifting point 21 of the upper part of the hydraulic grab beam 2A can be kept consistent with the size of the lifting point of the target object in the direction of the water flow by installing the lifting point offset plate on different sides of the grab beam body 20. Specifically, the thickness, position and number of the lifting point offset plate 35 can be set according to the corresponding groove width and the distance range of the lifting point of the target object to be lifted to the support surface when the hydraulic grab beam 2A is used. Preferably, the lifting point offset plate 35 is arranged on the side of the grab beam body 20 away from the positioning guide sleeve 31 in the width direction of the grab beam body 20. For example, when the hydraulic grab beam 2A is used to open or close a gate, since the center of gravity of the gate is biased downstream, the lifting point offset plate 35 needs to be installed at a position biased upstream (as shown in Figure 14 When the hydraulic grab beam 2A is used to open or close a trash rack, since the center of gravity of the trash rack is biased upstream, the lifting point offset plate 35 needs to be installed at a position biased downstream (as shown in Figure 15 When the hydraulic grab beam 2A is used to open or close a trash rack, since the center of gravity of the trash rack is biased upstream, the lifting point offset plate 35 needs to be installed at a position biased downstream (as shown in

[0067] Figure 16 The use method of the hydraulic grab beam 2A according to an embodiment of the present application is shown schematically.

[0068] The use method of the hydraulic grab beam 2A comprises the following steps:

[0069] S21: determining the position of the hydraulic pump station 22 on the grab beam body 20;

[0070] S22: setting the first counterbalance block 23 on the grab beam body 20 according to the eccentric moment generated by the hydraulic pump station 22 on the grab beam body 20, and ensuring that the value of the comprehensive eccentric moment generated by the hydraulic pump station 22 and the first counterbalance block 23 on the grab beam body 20 is less than 300 N·mm;

[0071] S23: setting the fixed counterweight block 24 on the grab beam body 20 according to the comprehensive eccentric moment, and ensuring that the value of the comprehensive eccentric moment generated by the hydraulic pump station 22, the first counterbalance block 23 and the fixed counterweight block 24 on the grab beam body 20 is zero.

[0072] Therefore, the eccentric moment of the hydraulic grab beam 2A can be initially balanced by the first counterbalance block 23, and then completely balanced by the fine adjustment of the fixed counterweight block 24.

[0073] Figure 17 The use method of the hydraulic grab beam 2A according to another embodiment of the present application is schematically shown.

[0074] S201: adjusting the position of the second counterbalance block 33 along the width direction of the grab beam body 20 by the first moving unit 32 according to the center of gravity position of the target object to be opened and closed, and locking the second counterbalance block 33 relative to the first moving unit 32 by the first locking unit 34 when the single lifting point 21 at the upper part of the hydraulic grab beam 2A and the center of gravity of the target object to be opened and closed are on the same vertical line.

[0075] Therefore, a group of hydraulic grab beams 2A can be used to open and close different sizes of gates (or trash racks); when a specific target object needs to be opened and closed, only the positioning guide sleeve 31 needs to be installed into the corresponding guide seat 25; and the first moving unit 32 can be used to drive the second counterbalance block 33 to move, so as to balance the different moments generated by different target objects on the single lifting point 21 at the upper part of the hydraulic grab beam 2A, and the first locking unit 34 can be used to enable the second counterbalance block 33 that has been moved to a position to be stably kept at the position.

[0076] Figure 18 The use method of the hydraulic grab beam 2A according to another embodiment of the present application is schematically shown.

[0077] S2001: determining the thickness of the lifting point offset plate 35 according to the distance from the opening and closing center of different target objects to be opened and closed to the corresponding slot;

[0078] S2002: The placement position of the lifting point offset plate 35 is determined according to the size of the slot corresponding to the target object to be opened or closed and the size of the lifting point of the target object to be opened or closed on the support surface of the corresponding slot in the width direction of the slot. For example, the lifting point offset plate 35 is arranged on the side of the grab beam body 20 away from the positioning guide sleeve 31 in the width direction thereof.

[0079] As one of the specific embodiments of step S2001, the thickness T of the lifting point offset plate 35 is set to be half of the distance difference between the opening and closing center of different target objects to be opened or closed and the corresponding slot, for example, when the slot width B of the gate slot is the same as the slot width B' of the trash rack slot 102, the distance Y1 from the opening and closing center to the gate slot when the gate is opened is different from the distance Y1' from the opening and closing center to the support surface of the trash rack slot 102, and the thickness T of the lifting point offset plate 35 is |Y-Y'| / 2.

Exemplarily, the first detection device 63 can be a commonly used detection device such as an infrared sensor or a contact sensor, or other commonly used detection devices. Exemplarily, the control module 61 can adopt a PLC or an MCU.

[0082] When the opening and closing machine is used with the opening and closing machine control system, the lifting unit 200 and the hydraulic grab beam 2A can be automatically driven to the position corresponding to the total gate slot 101 by the control module 61, the first positioning device 62 and the first detection device 63 to assist the opening and closing machine to realize automation.

[0083] In some preferred embodiments, continuing to refer to Figure 1 and Figure 19 , the opening and closing machine control system further comprises one of the second positioning device 64 and the second detection device 65 arranged on the pier 100 corresponding to the total gate slot 101, and the other of the second positioning device 64 and the second detection device 65 arranged on the opening and closing device 2; wherein the second detection device 65 is arranged to send a detection signal to the control module 61 when the second positioning device 64 is detected; the control module 61 is arranged to control the opening and closing device 2 to grab the sub gate 51 in the total gate slot 101 according to the received detection signal. Exemplarily, the second detection device 65 can be a commonly used detection device such as an infrared sensor or a contact sensor, or other commonly used detection devices. Thus, the lifting unit 200 and the hydraulic grab beam 2A can be automatically driven to the position of the total gate slot 101 by the control module 61, the second positioning device 64 and the second detection device 65 to assist the opening and closing machine to realize automation, specifically, the first rotating motor 121 in the first motion unit 1 is controlled.

[0084] In some preferred embodiments, as shown in Figure 1 , the first positioning device 62 is arranged on the pier 100, all the first positioning devices 62 are arranged along the direction in which the first motion unit 1 drives the opening and closing device 2 to move, and are arranged along the direction perpendicular to the direction in which the first motion unit 1 drives the opening and closing device 2 to move; the number of the first detection devices 63 is the same as the number of the first positioning devices 62, the first detection devices 63 are arranged on the opening and closing device 2, and all the first detection devices 63 are arranged along the direction perpendicular to the direction in which the first motion unit 1 drives the opening and closing device 2 to move. Thus, each first detection device 63 can detect one first positioning device 62 to ensure the accuracy of the first detection device 63.

[0085] In some preferred embodiments, as shown in Figure 19As shown, the control system of the hoist also comprises a height detection device 66 for detecting the height of the hoist device 2. The height detection device 66 is arranged on the frame 13. The height detection device 66 is arranged to send a height signal of the hoist device 2 to the control module 61. Thus, the hoist device 2 can be controlled by the control module 61 and the height detection device 66 to drive the hydraulic grab beam 2A to a set height, and automatically take and place the sub gate 51 at the set height, so as to assist the hoist to realize automation. For example, the height detection device 66 can be a displacement sensor or a distance measuring device commonly used in the prior art.

[0086] In some preferred embodiments, as shown in Figure 1 and Figure 19 As shown, the control system of the hoist also comprises a water level detection device 67 for detecting the water level. The water level detection device 67 is arranged on the pier 100. The water level detection device 67 is arranged to send a water level signal to the control module 61. Thus, the control module 61 can determine the nth gate to be opened or closed according to the water level signal collected by the water level detection device 67 and the water intake flow instruction, and control the hoist device 2 to place the nth gate to be opened or closed into the corresponding sub gate slot 410 or the total gate slot 101. For example, the water level detection device 67 can be a water level sensor commonly used in the prior art.

[0087] Figure 20 The control method of the control system of the hoist according to an embodiment of the present application is schematically shown.

[0088] As shown in Figure 20 The control method of the control system of the hoist comprises the following steps:

[0089] S31: The control module 61 controls the first movement unit 1 to transport the hoist device 2 to the total gate slot 101 according to the water level signal collected by the second detection device 65;

[0090] S32: The control module 61 controls the hoist device 2 to grab the sub gate 51 above the collected water level in the total gate slot 101 according to the height detection device 66;

[0091] S33: The control module 61 controls the first movement unit 1 to transport the hoist device 2 to the corresponding sub gate slot 410 according to the detection signal sent by the first detection device 63, and controls the hoist device 2 to place the grabbed sub gate 51 into the corresponding sub gate slot 410;

[0092] S34: repeating steps S31-S33 until the water level height at the top of the sub-gate 51 in the total gate slot 101 matches the collection water level height.

[0093] Figure 21 A control method of the control system for the hoist is schematically shown according to another embodiment of the present application.

[0094] As Figure 21 shown, the control method of the control system for the hoist includes the following steps:

[0095] S31`: the control module 61 controls the first movement unit 1 to transport the hoist device 2 to the corresponding sub-gate slot 410 according to the detection signal sent by the first detection device 63 based on the collection water level height signal;

[0096] S32`: the control module 61 controls the hoist device 2 to grab the sub-gate 51 in the corresponding sub-gate slot 410;

[0097] S33`: the control module 61 controls the first movement unit 1 to transport the hoist device 2 to the total gate slot 101 according to the detection signal sent by the second detection device 65, and controls the hoist device 2 to put the grabbed sub-gate 51 into the total gate slot 101;

[0098] S34`: repeating steps S31`-S33` until the water level height at the top of the sub-gate 51 in the total gate slot 101 matches the collection water level height.

[0099] Therefore, the hoist device 2 can be automatically driven to the position where the corresponding sub-gate slot 410 is located by the control module 61, the first positioning device 62, the first detection device 63, the auxiliary first movement unit 1, the height detection device 66, the second positioning device 64, and the second detection device 65, so as to facilitate the hoist to realize automation, thereby solving the problems of low intelligent degree and difficulty in realizing automatic operation and intelligent adjustment of water supply flow of the traditional hoist.

[0100] In some embodiments, the collection water level height signal is calculated by the control module 61 based on the water intake flow instruction received by the control module 61 and the water level height information detected by the water level detection device 67. Therefore, the hoist device 2 can be automatically driven to the position where the corresponding sub-gate slot 410 is located by the received water intake flow instruction and the water level detection device 67, as well as the control module 61, the first positioning device 62, the first detection device 63, the auxiliary first movement unit 1, the height detection device 66, the second positioning device 64, and the second detection device 65, so as to facilitate the hoist to realize automation.

[0101] When the control method of the control system of the gate hoist is used to operate the gate hoist, the water level detection device 67 can detect the water level height, and convert the water level height signal into a 4-20 mAn current output signal, and feed the output signal to the control module 61. After calculation by the control module 61, the number of sections of the gate to be opened and closed is determined. When the height of the gate does not reach the water level determined by the water level detection device 67, the control module 61 continues to issue instructions to the gate hoist 2, and the gate hoist 2 continues to open and close the gate (increase or decrease the number of sections of the gate), so as to finally achieve the purpose of automatically adjusting the water volume. The height of the gate hoist sub-gate 51 can be detected by the height detection device 66, and the lifting height signal of the lifting unit 200 is converted into a 4-20 mAn current output signal, and the output signal is fed back to the control module 61. Through the control module 61, the height of the sub-gate 51 is assigned to the first detection device 63 of the gate hoist 2, and the first detection device 63 of the gate hoist 2 is one-to-one corresponding to the first positioning device 62 above each gate slot. The gate height information is transmitted to the control module 61 by the height detection device 66, and the control module 61 decides to stop the nth gate at the Nth gate slot position of the centralized gate slot.

[0102] In the present application, the connection or installation is fixed connection without special emphasis. The fixed connection can be realized as detachable connection or non-detachable connection commonly used in the prior art. The detachable connection can be realized by the prior art, such as threaded connection or key connection. The non-detachable connection can also be realized by the prior art, such as welding or gluing.

[0103] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are all within the protection scope of the present application.
