Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy gates, and particularly relates to a mechanical linkage mechanism and method for hooking and unhooking of gates. Background Technique

[0002] Automatic hooking and unhooking beams for gates are increasingly used in water conservancy and hydropower projects in China. When a mobile hoist is used to operate multi-orifice gates or during the operation of gates where the hanging rods are frequently loaded and unloaded, it is more suitable to use an automatic hooking and unhooking beam.

[0003] In water conservancy and hydropower projects, automatic grasping beams for gates are quite widely used. When a mobile hoist is used to operate multi-orifice gates or when a laminated gate for maintenance is used and the gate is frequently lifted, it is particularly suitable to use an automatic grasping beam to ensure the accuracy of underwater work.

[0004] There are many forms of automatic grasping beams, but the principles of hooking and unhooking are basically the same. How to select a suitable form of automatic grasping beam needs to be determined according to the size of the gate and the lifting capacity of the automatic grasping beam. Forms of automatic grasping beams suitable for small gates include weight hammer hooking type, weight hammer rotating hook type, automatic hooking type, automatic lifting ring type, manual pin-passing type, etc. Forms of automatic grasping beams suitable for large and medium-sized gates include clamp type, freely hooking and unhooking type, hydraulic type, etc.

[0005] For the automatic grasping beam to successfully complete the hooking and unhooking operations, the design of the hook is the most crucial. According to some water conservancy units, when using the hooking and unhooking beam to lift the maintenance gate, there are problems such as inflexibility and jamming, and it is necessary to try repeatedly several times to successfully lift it. When lowering the maintenance gate, there are similar problems, resulting in difficulties in lifting and grasping, seriously affecting the improvement of the water gate management level, and at the same time increasing the daily maintenance cost. Summary of the Invention

[0006] The purpose of the present invention is to provide a mechanical linkage mechanism and method for hooking and unhooking of gates, which can utilize the lifting and lowering operation of the hooking and unhooking beam by the hoist to achieve automatic hooking and unhooking between the gate and between two sections of the gate.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A mechanical linkage mechanism for hooking and unhooking of gates, including a first hooking and unhooking assembly symmetrically arranged on the hooking and unhooking beam and a second hooking and unhooking assembly symmetrically arranged on the gate;

[0008] The first hooking and unhooking assembly includes a first hanging rod and a first rotating assembly. The first hanging rod is slidably installed on the hooking and unhooking beam. When it moves upward relative to the hooking and unhooking beam, it can be affected by the first rotating assembly and rotate around its own axis from a first angular position to a second angular position. When it moves downward relative to the hooking and unhooking beam, it can be affected by the first rotating assembly and rotate around its own axis from the second angular position to a third angular position;

[0009] The second hanging and disengaging assembly includes a second suspension rod, which is slidably installed on the gate. There is a mating groove at its top. The bottom hook body of the second suspension rod or the bottom hook body of the first suspension rod can be inserted into the mating groove below it to form a circumferential connection. After the gate is opened and after the first suspension rod descends to the limit position, the second suspension rod descends to the limit position relative to the gate. After the gates are stacked and installed and after the first suspension rod disengages from the second suspension rod below, the second suspension rod ascends to the limit position relative to the gate.

[0010] The first angular position corresponds to the state where the bottom hook of the first suspension rod can enter and exit the through hole of the gate lug plate below and the state where the bottom of the second suspension rod can enter and exit the through hole of the gate lug plate below. The third angular position corresponds to the state where the bottom hook of the first suspension rod can hook the through hole of the gate lug plate below and the state where the bottom hook of the second suspension rod can hook the through hole of the gate lug plate below.

[0011] Further, the first rotating assembly includes an upper bushing and a lower bushing coaxially installed on the body of the hanging and disengaging beam. The first suspension rod is equipped with a double-tooth bushing. The first suspension rod is slidably sleeved and connected with the upper bushing and the lower bushing.

[0012] Both the bottom of the upper bushing and the top of the lower bushing have a number of first sawteeth. Both the upper and lower ends of the double-tooth bushing have second sawteeth that match the first sawteeth.

[0013] When the first suspension rod moves to the position where the second sawteeth of the double-tooth bushing cooperate with the first sawteeth, the first suspension rod generates a circumferential rotation.

[0014] Further, the first suspension rod includes a first rod body and a first hook body. The first hook body is installed at the bottom of the first rod body, and the double-tooth bushing is installed on the first rod body.

[0015] Further, the first rod body has an upper convex platform and a lower convex platform that limit the movement position of the first rod body relative to the hanging and disengaging beam.

[0016] Further, the second hanging and disengaging assembly further includes a positioning bushing installed on the gate and a suspension rod spring that provides an upward force to move the second suspension rod to the limit position. The second suspension rod is slidably sleeved and connected with the positioning bushing.

[0017] Further, the second suspension rod includes a second rod body and a second hook body. The second hook body is installed at the bottom of the second rod body.

[0018] Further, the bottom of the second rod body has a receiving hole, and the top of the second hook body is installed in the receiving hole.

[0019] Further, the second suspension rod is provided with a positioning convex platform. When the second suspension rod descends to the limit position, the positioning convex platform contacts the top of the positioning bushing.

[0020] Further, it further includes two locking mechanisms installed on the uppermost section of the gate, and the locking mechanisms can drive the second suspension rod to rotate from the third angular position to the first angular position under the action of the first suspension rod.

[0021] The present invention also provides a mechanical linkage method for gate hanging and detachment, including a hanging beam operation and a beam detachment operation;

[0022] During the hanging beam operation, when the first suspension rod at the first angular position descends to the limit position along with the hanging and detaching beam, and then the hanging and detaching beam continues to descend until the first rotating assembly cooperates with the first suspension rod and drives the first suspension rod to rotate to the second angular position, and then the hanging and detaching beam rises. The second suspension rod at the second angular position cooperates with the first rotating assembly again and is driven by it to rotate to the third angular position, and the second suspension rod hooks onto the lug plate of the gate below;

[0023] During the beam detachment operation, when the first suspension rod at the third angular position descends to the limit position along with the hanging and detaching beam, and then the hanging and detaching beam continues to descend until the first rotating assembly cooperates with the first suspension rod and drives the first suspension rod to rotate to the second angular position, and then the hanging and detaching beam rises. The second suspension rod at the second angular position cooperates with the first rotating assembly again and is driven by it to rotate to the first angular position, and the second suspension rod disengages from the lug plate of the gate below;

[0024] In the above operations, after the first suspension rod and the second suspension rod are butted and form a circumferential connection, the two rotate the same angle together, so that the second suspension rod hooks onto or disengages from the lug plate of the gate below.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) The present invention adopts the form of "self - hanging and detaching grab beam", adds upper and lower limit meshing devices, significantly improves the accuracy of hanging and detaching, eliminates the danger of falling caused by jamming during the hoisting of the gate, and thus improves and perfects the function of the "self - hanging and detaching grab beam". It is not only applicable to medium and small tonnages, but also more prominent in the hanging and detaching beam effects of large, medium and extra - large tonnage capacities. It can replace various types of automatic grab beams used in the past, without increasing its own weight, and is simple and easy to manufacture.

[0027] (2) The working mechanism of the present invention has a simple structure, the design and manufacturing dimensions of the suspension shaft are easy to control, the operation is convenient, the main mechanism is directly connected to the hoist spreader, the force is clear, and it will not increase the weight of the equipment. The upper and lower shaft sleeves and the suspension shaft inlaid with wedges are all made of self - lubricating nylon material. When rotating and transmitting, it only bears the weight of the hanging and detaching beam itself and its tiny impact force control. Also, the rotating operation mode makes it more light and flexible. The shaft has fewer stepped sections, is simple to manufacture, further improves the strength and reliability of the shaft, and optimizes the power transmission.

[0028] (3)All mechanical operations are involved in the present invention without electrical equipment, and it can safely hook and unhook the gate deep in the water. The project cost is low, it is economical and practical, and different series of hoisting shaft diameters can be designed according to gates of different tonnages, which is convenient for the standardization, serialization and generalization of the opening and closing device.

[0029] (4)The double-tooth part bushing in the present invention is detachably installed, which is convenient for maintenance. It can operate with only one tooth part. The present invention has a redundant design, which can improve the service life of the double-tooth part bushing as soon as possible and reduce the number of maintenance times.

[0030] (5)The corresponding gate hooking and unhooking top plate in the present invention has a simple structure and is easy to manufacture and install. The overall strength of the hook is good, the force is evenly distributed, and no local stress will be generated to cause damage. Description of the Drawings

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0049] As Figures 1 to 15 shown, this embodiment discloses a mechanical linkage mechanism for gate hanging and disengaging, including a first hanging and disengaging assembly 2 and a second hanging and disengaging assembly 9. Two first hanging and disengaging assemblies 2 are symmetrically arranged on the hanging and disengaging beam 1 and are respectively close to both ends of the hanging and disengaging beam 1. Two second hanging and disengaging assemblies 9 are symmetrically arranged on the gate 3 and are coaxially aligned with the first hanging and disengaging assemblies 2 on the same side. The gate 3 in the present invention is preferably a laminated gate, and the laminated gate has a plurality of gates 3 connected in series up and down. When applying such a gate 3 in the present invention, except for the last gate 3, the second hanging and disengaging assemblies 9 are installed on the remaining gates 3. A limit plate is provided at the position corresponding to the upper second hanging and disengaging assembly 9 on the last gate 3 for the ultimate limit of the upper second hanging and disengaging assembly 9.

[0050] The first hanging and detaching component 2 includes a first hanging rod and a first rotating component. The first hanging rod is slidably installed on the hanging and detaching beam 1. When it moves upward relative to the hanging and detaching beam 1, it can be affected by the first rotating component and rotate around its own axis from the first angular position to the second angular position. When it moves downward relative to the hanging and detaching beam 1, it can be affected by the first rotating component and rotate around its own axis from the second angular position to the third angular position. In this example, the angle of a single rotation of the first hanging rod is set to 45°. That is to say, the included angle between the first angular position and the second angular position and the included angle between the second angular position and the third angular position are both 45°.

[0051] As a preferred example, the first rotating component includes an upper shaft sleeve 23 and a lower shaft sleeve 26 coaxially installed on the body of the hanging and detaching beam 1. The first hanging rod is installed with a double-toothed shaft sleeve 24. The first hanging rod is slidably sleeved and connected with the upper shaft sleeve 23 and the lower shaft sleeve 26. Both the upper shaft sleeve 23 and the lower shaft sleeve 26 are provided with end face bosses, so as to be positioned and installed on the top surface and the bottom surface of the hanging and detaching beam 1. The end face bosses are both located outside the top surface and the bottom surface of the hanging and detaching beam 1.

[0052] Both the bottom of the upper shaft sleeve 23 and the top of the lower shaft sleeve 26 have four first sawteeth evenly distributed in the circumferential direction. Both the upper and lower ends of the double-toothed shaft sleeve 24 have second sawteeth matching the first sawteeth. The first sawteeth of the upper shaft sleeve 23 and the first sawteeth of the lower shaft sleeve 26 are staggered by 45° in the circumferential direction.

[0053] When the first hanging rod moves, when the second sawteeth at one end of the double-toothed shaft sleeve 24 cooperate with the corresponding first sawteeth, it will drive the first hanging rod to rotate circumferentially by 45°.

[0054] For the convenience of maintenance, the first hanging rod adopts a split design. As a preferred example, the first hanging rod includes a first rod body 5 and a first hook body 6. The first hook body 6 is installed at the bottom of the first rod body 5 by a pin shaft and is fixedly connected relative to the first rod body 5. The double-toothed shaft sleeve 24 is fixedly installed on the first rod body 5 by screws. When the first rod body 5 moves up and down, the first hook body 6 moves up and down together.

[0055] As a preferred example, the first rod body 5 has an upper boss 22 and a lower boss 25 that limit the movement position of the first rod body 5 relative to the hanging and detaching beam 1. The upper boss 22 moves above the top surface of the hanging and detaching beam 1, and the lower boss 25 moves below the bottom surface of the hanging and detaching beam 1. When the upper boss 22 moves to contact the end face boss of the upper shaft sleeve 23, the first rod body 5 is in the maximum descending position relative to the hanging and detaching beam 1. On the contrary, when the lower boss 25 moves to contact the end face boss of the lower shaft sleeve 26, the first rod body 5 is in the maximum ascending position relative to the hanging and detaching beam 1.

[0056] The second hanging and disengaging assembly 9 includes a second suspension rod which is slidably mounted on the gate 3. A mating groove 16 is provided at the top thereof. The bottom hook body of the second suspension rod or the bottom hook body of the first suspension rod can be inserted into the mating groove 16 below it to form a circumferential connection. The purpose of forming a circumferential connection between the first suspension rod and the second suspension rod is to drive the synchronous rotation of all the second suspension rods in the same axial direction through the rotation of the first suspension rod, so as to realize the hooking and unhooking operations of all the gates 3, and finally achieve the overall linkage control purpose.

[0057] As a preferred example, the second hanging and disengaging assembly further includes a positioning bushing 12 mounted on the gate 3 and a suspension rod spring 11 that provides an upward force for the second suspension rod to move to the extreme position. The second suspension rod is slidably sleeved with the positioning bushing 12. The positioning bushing 12 has two functions. One is to realize the sliding installation of the second suspension rod, that is, the second suspension rod can slide up and down in the positioning bushing 12; the other is to position the second suspension rod, that is, the maximum descending position of the second suspension rod is restricted by the positioning bushing 12.

[0058] For the convenience of maintenance, the second suspension rod is designed in a split type. As a preferred example, the second suspension rod includes a second rod body 10 and a second hook body 15, and the second hook body 15 is mounted at the bottom of the second rod body 10.

[0059] For the convenience of disassembly and installation of the second hook body 15, as a preferred example, a receiving hole is provided at the bottom of the second rod body 10, and the top of the second hook body 15 is mounted in the receiving hole by a pin shaft, so that the second rod body 10 and the second hook body 15 are fixedly connected.

[0060] As a preferred example, the second suspension rod is provided with a positioning boss 17. When the second suspension rod descends to the extreme position, the positioning boss 17 contacts the top of the positioning bushing 12, so as to prevent the second suspension rod from disengaging from the positioning bushing 12. On the other hand, since the second suspension rod will descend to the extreme position and will no longer descend, the uppermost gate 3 will provide a force application point for the upper first suspension rod, so that the first suspension rod cooperates with the upper bushing 23 to rotate. That is to say, when the first suspension rod descends, it will press down the second suspension rod to make it descend to the extreme position. At this time, the second suspension rod will no longer descend and provide an upward force for the first suspension rod, thus completing the rotation operation.

[0061] After the gate 3 is opened and after the first suspension rod descends to the extreme position, the second suspension rod descends to the extreme position relative to the gate 3; after the gates 3 are stacked and installed and after the first suspension rod disengages from the second suspension rod below, the second suspension rod rises to the extreme position relative to the gate 3.

[0062] The first angular position corresponds to the state where the bottom hook of the first suspension rod can enter and exit the through hole 4 of the gate lug plate below, and the state where the bottom of the second suspension rod can enter and exit the through hole 4 of the gate lug plate below. The third angular position corresponds to the state where the bottom hook of the first suspension rod can hook the through hole 4 of the gate lug plate below, and the state where the bottom hook of the second suspension rod can hook the through hole 4 of the gate lug plate below.

[0063] Generally speaking, lifting lugs 7 are provided on the gate 3, and a through hole 4 of the gate lug plate is provided on the lifting lug 7 for hooking and unhooking with the first suspension rod and the second suspension rod. When the bottom hook bodies of the first suspension rod and the second suspension rod are at the first angular position, they can freely pass through the through hole 4 of the gate lug plate. When rotated to the third angular position, the bottoms of both cannot pass through the through hole 4 of the gate lug plate. That is to say, when both are below the lifting lug 7, moving them upward will form a hook connection with the lifting lug 7. As a preferred example, the through hole 4 of the gate lug plate is a rectangular hole or a special-shaped hole. The special-shaped hole has a circular part and rectangular parts on both sides of the circular part. The rectangular hole is convenient for processing and manufacturing. The shapes of the bottoms of the first hook body 6 and the second hook body 15 are both semi-circular.

[0064] As a preferred example, in order to be able to unhook the two adjacent gates 3 above and below to facilitate the hanging and detaching beam 1 to separately hook each section of the gate 3, as Figure 9 shown, the linkage mechanism in the present invention further includes two lock gate mechanisms installed on the topmost section of the gate 3. The lock gate mechanisms are located behind the second suspension rod, that is, in the direction of the water-retaining side. The lock gate mechanisms can be driven by the first suspension rod to drive the second suspension rod to sequentially switch between the first angular position and the first angular position. Specifically, the lock gate mechanism includes a rack 14, a gear 21, a limit block 19, and a return spring 18. The rack 14 is horizontally slidably installed on the gate 3. The gear 21 is correspondingly installed on the second suspension rod of this section of the gate 3 through a one-way bearing 13. A wedge block 20 is provided on one side of the rack 14, and one end abuts against the return spring 18. The limit block 19 is used to limit the moving distance of the rack 14.

[0065] When the hanging and detaching beam 1 disengages from the first section of the gate 3, it moves in the direction perpendicular to the gate 3 towards the water-retaining side under the drive of the trolley, and makes the first suspension rod exactly above the wedge block 20. When the first suspension rod descends and touches the wedge block 20, it will drive the rack 14 to move until it is limited by the limit block 19. During this process, the second suspension rod rotates by 90°, thereby realizing the locking and unlocking of the second suspension rod and the lower gate 3. When the first suspension rod moves upward and leaves the wedge block 20, the rack 14 is reset under the action of the return spring 18. However, since a one-way gear 21 is provided between the gear 21 and the second suspension rod and there is frictional resistance between the second suspension rods, the second suspension rod will not rotate with the one-way gear 21 and thus remains at the first angular position. Embodiment

[0066] The present invention also provides a mechanical linkage method for hanging and detaching a gate 3, including a hanging beam operation and a detaching beam operation;

[0067] As Figure 12 shown, during the hanging beam operation, since the last section of the gate 3 has no second hanging and detaching component 9, the hanging beam operation is divided into two cases. One is the hanging beam operation for the last section of the gate 3. The hanging and detaching beam 1 starts to descend from the initial height H1 driven by the hoist. During this process, the double-tooth sleeve 24 cooperates with the lower sleeve 26, and the first suspension rod is in the first angular position. As Figure 13 shown, when the hanging and detaching beam 1 descends to the first height H2, the bottom hook body of the first suspension rod in the first angular position passes through the through hole of the gate hanger plate 4 and descends to the limit position, and this limit position is determined by the top surface of the positioning plate 27 on the last section of the gate 3. As Figure 14 shown, at this time, control the hanging and detaching beam 1 to continue descending the second height H3. During this process, the double-tooth sleeve 24 disengages from the lower sleeve 26 and cooperates with the upper sleeve 23, so that the first suspension rod rotates to the second angular position under the action of the sawtooth cooperation, and the rotation angle is 45°. At this time, the hanging and detaching beam 1 stops descending. As Figure 15 shown, the hoist controls the hanging and detaching beam 1 to rise to the third height H4. At this time, the double-tooth sleeve 24 disengages from the upper sleeve 23 and cooperates with the lower sleeve 26 again, so that the first suspension rod rotates to the third angular position again. At this time, the first suspension rod is hooked to the hanger plate 7 of this section of the gate 3, and the hanging beam operation is completed.

[0068] The other is the hanging beam operation for the remaining sections of the gate 3. The general process is the same. The difference is that when the bottom hook body of the first suspension rod passes through the through hole of the gate hanger plate 4 and descends to the limit position, this limit position is determined after being connected to the top of the second suspension rod on this section of the gate 3. That is to say, the second suspension rod will also descend to the limit position under the pressure of the first suspension rod. At this time, the first suspension rod no longer continues to descend and also comes to the limit position. After that, through the same operation, the first suspension rod is hooked to the hanger plate 7 of this section of the gate 3, and the hanging beam operation is completed.

[0069] During the detaching beam operation, the process is similar to the hanging beam operation. The hanging and detaching beam 1 descends to the first height H2 driven by the hoist. At this time, the first suspension rod in the third angular position descends to the limit position. At this time, continue to control the hanging and detaching beam 1 to descend to the second height H3. The double-tooth sleeve 24 disengages from the lower sleeve 26 and cooperates with the upper sleeve 23, so as to drive the first suspension rod to rotate to the second angular position. Then control the hanging and detaching beam 1 to rise to the third height H4. At this time, the double-tooth sleeve 24 disengages from the upper sleeve 23 and cooperates with the lower sleeve 26, so as to drive the first suspension rod to rotate to the first angular position. Then continue to control the hanging and detaching beam 1 to rise, and the bottom hook body of the first suspension rod disengages from the hanger plate 7, and the detaching beam operation is completed.

[0070] In the above operation, the initial angular positions of the first suspension rod and the second suspension rod are both the first angular position, so that the bottom hook bodies of both can pass through the through holes 4 of the corresponding gate lug plates. After the first suspension rod and the second suspension rod are butted and circumferentially connected, the two rotate the same angle together, so that the second suspension rod is hooked or unhooked from the lug plate 7 of the lower gate 3. That is to say, when the first suspension rod rotates to any angular position, the second suspension rod also rotates to the same angular position.

[0071] When installing the gate 3, the steps of installing the hanging beam operation and the beam removal operation install each section of the gate 3 in the gate slot of the gate 3, and water blocking can be achieved after all the gates 3 are installed. However, when the gate needs to be opened, the topmost section of the gate 3 is hooked using the first suspension rod according to the steps of the hanging beam operation. During this process, all the second suspension rods also rotate with the first suspension rod to hook the upper and lower gates 3. At this time, when the hanging and removing beam 1 is lifted, all the gates 3 can be lifted to open the gate and release water.

[0072] It should be noted that when two adjacent gates 3 both provided with the second hanging and removing assembly 9 are installed one by one, since the lower gate 3 has completed the beam removal operation, its second suspension rod is in the first angular position. Before the upper gate 3 is disconnected from the hanging and removing beam, the second suspension rod on the upper gate 3 is in the second angular position. Therefore, when the upper gate 3 is placed on the top surface of the lower gate 3, no circumferential connection is formed between the two second suspension rods. After the upper gate 3 is disconnected from the hanging and removing beam, the second suspension rod on the upper gate 3 is in the first angular position, and at this time, a circumferential connection is formed with the second suspension rod on the lower gate 3. The remaining gates 3 are all installed in this way in sequence.

[0073] It should also be noted that when the gate 3 is lifted as a whole, among two adjacent gates, the upper gate 3 is first subjected to the pulling force of the hoist relative to the lower gate 3. At the same time, when lifting, the second suspension rod will descend relative to this section of the gate 3, so that the same spacing gaps are generated between all the gates 3. That is to say, when opening the gate, the load initially received by the hoist is only the weight of the first section of the gate. Then, as the gate is lifted, the load gradually increases. It can be seen that compared with the integral gate opening in the prior art, adopting this structure for gate opening operation can greatly reduce the initial instantaneous load of the hoist, which helps to extend the service life of the hoist. On the other hand, since gaps appear between the upper two gates when opening the gate, the water on the water-facing side of the gate flows to the water-back side through the gaps, which will reduce the pressure difference on both sides of the following several gates, improve the stress condition of the gate, reduce the deformation of the gate, help to extend the service life of the gate. At the same time, the reduction of the pressure difference also means that the opening and closing force provided by the hoist is also reduced, making it more convenient to lift the gate.

[0074] When the gate 3 needs to be removed from the gate slot of the gate 3, it can be lifted above the gate slot of the gate 3 on the basis of the gate opening operation. After being transferred to other places, the gate 3 can be removed from the beam and stored in the warehouse.

[0075] Due to the adoption of the gate locking mechanism, each section of the gate can be lifted and fixed on one side of the top of the slot or in the gate warehouse in sequence when opening the gate. This method requires a lower power for the hoist, and as each section of the gate is lifted, the water pressure on the lower gate becomes more balanced, which helps to achieve hydrostatic balance, reduce the deformation of the gate, and contribute to extending the service life of the gate.
