Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic gates, and in particular relates to a mechanical linkage mechanism and method for hanging and unhanging a gate. Background Art

[0002] Automatic gate hanging and detaching beams are increasingly used in my country's water conservancy and hydropower projects. When a mobile gate hoist is used to operate a multi-hole gate or when the gate is frequently loaded and unloaded during operation, it is more appropriate to use an automatic hanging and detaching beam.

[0003] In water conservancy and hydropower projects, the application of automatic gate grab beams is quite extensive. When a mobile gate hoist is used to operate a multi-hole gate or a stacked beam gate is used for maintenance, and the gate is frequently hoisted, the automatic grab beam is particularly suitable to ensure the accuracy of underwater work.

[0004] There are many types of automatic grab beams, but the principles of hooking and unhooking are basically the same. How to choose the appropriate type of automatic grab beam needs to be determined according to the size of the gate and the lifting capacity of the automatic grab beam. The automatic grab beam types suitable for small gates include heavy hammer hook type, heavy hammer rotating hook type, automatic hook type, automatic lifting ring type, manual pin type, etc. The automatic grab beam types suitable for large and medium-sized gates include clamp type, free hook and unhooking type, hydraulic type, etc.

[0005] The automatic grab beam must successfully complete the hooking and unhooking operations. Whether the hook design is reasonable is the most critical. According to some water pipe units, when using the hooking and unhooking beam to lift the inspection door, there are problems such as discomfort and sticking. Repeated attempts are required to successfully lift it. Similar problems also exist when lowering the inspection door, resulting in difficulties in lifting and grabbing, which seriously affects the improvement of the sluice management level and also increases the cost of daily maintenance. Summary of the invention

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

[0007] To achieve the above object, the present invention provides the following technical solution: a mechanical linkage mechanism for gate hooking and unhooking, comprising a first hooking and unhooking component symmetrically arranged on a hooking and unhooking beam and a second hooking and unhooking component symmetrically arranged on the gate; The first hanging assembly includes a first suspension rod and a first rotating assembly. The first suspension rod is slidably mounted on the hanging beam. When the first suspension rod moves upward relative to the hanging beam, it can be acted upon by the first rotating assembly to rotate around its own axis from a first angular position to a second angular position. When the first suspension rod moves downward relative to the hanging beam, it can be acted upon by the first rotating assembly to rotate around its own axis from the second angular position to a third angular position. The second hanging and releasing assembly includes a second hanging rod, which is slidably mounted on the gate and has a matching groove on its top, and the bottom hook of the second hanging rod or the bottom hook of the first hanging rod can be inserted into the matching groove below it to form a circumferential connection; after the gate is opened and the first hanging rod is lowered to the limit position, the second hanging rod is lowered to the limit position relative to the gate; after the gate is stacked and installed and the first hanging rod is separated from the second hanging rod below, the second hanging rod is raised to the limit position relative to the gate; The first angle position corresponds to a state in which the bottom hook of the first suspension rod can enter and exit the through hole of the gate ear plate below and the bottom of the second suspension rod can enter and exit the through hole of the gate ear plate below. The third angle position corresponds to a state in which the bottom hook of the first suspension rod can hook the through hole of the gate ear plate below and the bottom hook of the second suspension rod can hook the through hole of the gate ear plate below.

[0008] Furthermore, the first rotating assembly includes an upper sleeve and a lower sleeve coaxially mounted on the hanging beam body, and the first suspension rod is mounted with a double-tooth sleeve; the first suspension rod is connected with the upper sleeve and the lower sleeve in a sliding sleeve; The bottom of the upper sleeve and the top of the lower sleeve are both provided with a plurality of first saw teeth, and the upper and lower ends of the double-tooth sleeve are both provided with second saw teeth matching the first saw teeth; When the first suspension rod moves to the point where the second saw teeth of the double-toothed sleeve are matched with the first saw teeth, the first suspension rod generates a circumferential rotation.

[0009] Furthermore, 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-toothed sleeve is installed on the first rod body.

[0010] Furthermore, the first rod body has an upper boss and a lower boss for limiting the movement position of the first rod body relative to the hook-and-release beam.

[0011] Furthermore, the second rotating assembly includes a positioning sleeve installed on the gate and a suspension rod spring providing a force for the second suspension rod to move upward to the limit position, and the second suspension rod is connected to the positioning sleeve in a sliding sleeve.

[0012] Furthermore, the second suspension rod includes a second rod body and a second hook body, and the second hook body is installed at the bottom of the second rod body.

[0013] Furthermore, 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.

[0014] Furthermore, the second suspension rod is provided with a positioning boss, and when the second suspension rod is lowered to the extreme position, the positioning boss contacts the top of the positioning sleeve.

[0015] Furthermore, it also includes two gate locking mechanisms installed on the uppermost gate section, and the gate locking mechanisms can be driven by the first suspension rod to drive the second suspension rod to rotate from the third angle position to the first angle position.

[0016] The present invention also provides a mechanical linkage method for gate hanging and unhanging, including beam hanging operation and beam unhanging operation; During the hanging beam operation, after the first hanging rod at the first angle position is lowered to the limit position along with the hanging and removing beam, the hanging and removing beam continues to be lowered to the first rotating assembly to cooperate with the first hanging rod and drive the first hanging rod to rotate to the second angle position, and then the hanging and removing beam rises, and the second hanging rod at the second angle position cooperates with the first rotating assembly again and is driven by it to rotate to the third angle position, and the second hanging rod is hooked with the hanging ear plate of the gate below; During the beam-dropping operation, after the first suspension rod at the third angle position is lowered to the limit position along with the hanging and dropping beam, the hanging and dropping beam continues to drop to the first rotating assembly to cooperate with the first suspension rod and drive the first suspension rod to rotate to the second angle position, and then the hanging and dropping beam rises, and the second suspension rod at the second angle position cooperates with the first rotating assembly again and is driven by it to rotate to the first angle position, and the second suspension rod is unhooked from the lug plate of the gate below; In the above operation, after the first suspension rod and the second suspension rod are butted against each other and form a circumferential connection, the two are rotated together at the same angle, so that the second suspension rod is hooked or unhooked with the lug plate of the gate below.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention adopts the form of a "free-hanging and detaching grab beam" and adds upper and lower limit engagement devices, which significantly improves the accuracy of hanging and detaching, eliminates the danger of falling due to blocking during the gate lifting process, and thus improves and perfects the function of the "free-hanging and detaching grab beam". It is not only suitable for small and medium-sized tonnage, but also has a more prominent effect on large, medium and extra-large tonnage capacity. It can replace various types of automatic grab beams used in the past, does not increase its own weight, and is simple and easy to manufacture.

[0018] (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, and the operation is convenient. The main mechanism is directly connected to the hoisting device, and the force is clear, which will not increase the weight of the equipment. The upper and lower shaft sleeves and the suspension shaft embedded wedges are made of self-lubricating nylon. During the rotation transmission, they only bear the deadweight of the hanging beam itself and its tiny impact force control. The rotation operation mode makes it more light and flexible. The shaft has few stepped sections and is simple to manufacture. The strength and reliability of the shaft are further improved, and the power transmission is optimized.

[0019] (3) The present invention is fully mechanically operated, without electrical equipment, and can safely hang and detach the gate deep into the water. The project cost is low, economical and practical, and different series of hanging shaft diameters can be designed according to gates of different tonnages, which is convenient for standardization, serialization and universalization of the opening and closing locking device.

[0020] (4) The double-toothed sleeve in the present invention is detachable and easy to maintain, and can be operated with only one tooth. The present invention has a redundant design, which can quickly increase the service life of the double-toothed sleeve and reduce the number of maintenance times.

[0021] (5) The gate hook and detachable top plate of the present invention has a simple structure and is easy to manufacture and install. The hook has good overall strength and is evenly stressed, and will not generate local stress and cause damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1: Figures 1 to 15 As shown, the present embodiment discloses a mechanical linkage mechanism for gate hooking and unhooking, including a first hooking and unhooking component 2 and a second hooking and unhooking component 9. Two first hooking and unhooking components 2 are symmetrically arranged on the hooking and unhooking beam 1, and are respectively close to the two ends of the hooking and unhooking beam 1. Two second hooking and unhooking components 9 are symmetrically arranged on the gate 3, and are coaxially aligned with the first hooking and unhooking components 2 on the same side. The gate 3 in the present invention is preferably a stacked beam gate, and the stacked beam gate has a plurality of gates 3 connected in series up and down. When the present invention applies such a gate 3, except for the last section of the gate 3, the remaining gates 3 are all installed with the second hooking and unhooking component 9. A limit plate is provided at the position of the second hooking and unhooking component 9 above the last section of the gate 3, which is used for the extreme limit of the second hooking and unhooking component 9 above.

[0026] The first hanging assembly 2 includes a first suspension rod and a first rotating assembly. The first suspension rod is slidably mounted on the hanging beam 1. When the first suspension rod moves upward relative to the hanging beam 1, it can be affected by the first rotating assembly and rotate around its own axis from the first angle position to the second angle position. When the first suspension rod moves downward relative to the hanging beam 1, it can be affected by the first rotating assembly and rotate around its own axis from the second angle position to the third angle position. In this example, the angle of a single rotation of the first suspension rod is set to 45°, that is, the angle between the first angle position and the second angle position and the angle between the second angle position and the third angle position are both 45°.

[0027] As a preferred example, the first rotating assembly includes an upper sleeve 23 and a lower sleeve 26 coaxially mounted on the main body of the hanging beam 1, and the first suspension rod is installed with a double-tooth sleeve 24; the first suspension rod is slidably connected with the upper sleeve 23 and the lower sleeve 26. The upper sleeve 23 and the lower sleeve 26 are both provided with end face bosses, so as to be positioned and mounted on the top and bottom surfaces of the hanging beam 1, and the end face bosses are both located on the outer side of the top and bottom surfaces of the hanging beam 1.

[0028] The bottom of the upper sleeve 23 and the top of the lower sleeve 26 both have four first serrations evenly distributed around the circumference, and the upper and lower ends of the double-tooth sleeve 24 both have second serrations matching the first serrations. The first serrations of the upper sleeve 23 and the first serrations of the lower sleeve 26 are staggered 45° in the circumferential direction.

[0029] When the first suspension rod moves, when the second saw teeth at one end of the double-toothed sleeve 24 cooperate with the corresponding first saw teeth, the first suspension rod is driven to rotate 45° in the circumferential direction.

[0030] In order to facilitate maintenance, the first suspension rod adopts a split design. As a preferred example, the first suspension 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 and is fixedly connected relative to the first rod body 5. The double-toothed sleeve 24 is fixedly installed on the first rod body 5 by screws. When the first rod body 5 is raised or lowered, the first hook body 6 is raised or lowered together.

[0031] As a preferred example, the first rod body 5 has an upper boss 22 and a lower boss 25 for limiting the movement position of the first rod body 5 relative to the hook beam 1. The upper boss 22 moves above the top surface of the hook beam 1, and the lower boss 25 moves below the bottom surface of the hook beam 1. When the upper boss 22 moves to contact the end face boss of the upper sleeve 23, the first rod body 5 is in the maximum descending position relative to the hook beam 1, and conversely, when the lower boss 25 moves to contact the end face boss of the lower sleeve 26, the first rod body 5 is in the maximum ascending position relative to the hook beam 1.

[0032] The second hook-and-release assembly 9 includes a second suspension rod, which is slidably mounted on the gate 3, and has a matching groove 16 on its top, and the bottom hook of the second suspension rod or the bottom hook of the first suspension rod can be inserted into the matching groove 16 below it to form a circumferential connection. The purpose of the circumferential connection between the first suspension rod and the second suspension rod is to drive the synchronous rotation of all the second suspension rods on the same axis through the rotation of the first suspension rod, thereby realizing the hooking and unhooking operations of all the gates 3, and finally achieving the overall linkage control purpose.

[0033] As a preferred example, the second rotating assembly further includes a positioning sleeve 12 mounted on the gate 3 and a suspension spring 11 providing a force for the second suspension rod to move upward to the limit position, and the second suspension rod is slidably connected with the positioning sleeve 12. The positioning sleeve 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 sleeve 12; the other is to realize the positioning of the second suspension rod, that is, the maximum descending position of the second suspension rod is limited by the positioning sleeve 12.

[0034] In order to facilitate maintenance, the second suspension rod adopts a split design. 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 installed at the bottom of the second rod body 10 .

[0035] To facilitate the disassembly and installation of the second hook body 15 , as a preferred example, the bottom of the second rod body 10 has a receiving hole, and the top of the second hook body 15 is installed in the receiving hole using a pin shaft, so that the second rod body 10 and the second hook body 15 are fixedly connected.

[0036] As a preferred example, the second suspension rod is provided with a positioning boss 17. When the second suspension rod is lowered to the limit position, the positioning boss 17 contacts the top of the positioning sleeve 12, thereby preventing the second suspension rod from coming out of the positioning sleeve 12. On the other hand, since the second suspension rod will be lowered to the limit position and will not be lowered any more, the uppermost gate 3 will provide a force point for the first suspension rod above, so that the first suspension rod cooperates with the upper sleeve 23 to rotate. In other words, when the first suspension rod is lowered, it will press down the second suspension rod to make it drop to the limit position. At this time, the second suspension rod will no longer be lowered and will provide an upward force to the first suspension rod, thereby completing the rotation operation.

[0037] After the gate 3 is opened and the first suspension rod is lowered to the extreme position, the second suspension rod is lowered to the extreme position relative to the gate 3; after the gate 3 is stacked and installed and the first suspension rod is separated from the second suspension rod below, the second suspension rod is raised to the extreme position relative to the gate 3.

[0038] The first angle position corresponds to the state that the bottom hook of the first suspension rod can enter and exit the through hole 4 of the gate ear plate below and the state that the bottom of the second suspension rod can enter and exit the through hole 4 of the gate ear plate below. The third angle position corresponds to the state that the bottom hook of the first suspension rod can hook the through hole 4 of the gate ear plate below and the state that the bottom hook of the second suspension rod can hook the through hole 4 of the gate ear plate below.

[0039] Generally speaking, the gate 3 is provided with a lug plate 7, and the lug plate 7 is provided with a gate lug plate through hole 4 for hooking and unhooking with the first suspension rod and the second suspension rod. When the bottom hook of the first suspension rod and the bottom hook of the second suspension rod are at the first angle position, they can freely pass through the gate lug plate through hole 4. When they are rotated to the third angle position, the bottoms of the two cannot pass through the gate lug plate through hole 4. In other words, when the two are located below the lug plate 7, they will be hooked with the lug plate 7 when they move upward. As a preferred example, the gate lug plate through hole 4 is a rectangular hole or a special-shaped hole. The special-shaped hole has a circular part and rectangular parts located on both sides of the circular part. The rectangular hole is easy to process and manufacture. The shape of the bottom of the first hook body 6 and the bottom of the second hook body 15 are both semicircular.

[0040] As a preferred example, in order to enable the upper and lower adjacent gates 3 to be unhooked so that the hanging beam 1 can hang each gate 3 separately, as shown in FIG. Fig. 9 As shown, the linkage mechanism in the present invention also includes two gate locking mechanisms installed on the top section of the gate 3, and the gate locking mechanism is located behind the second suspension rod, that is, in the backwater direction. The gate locking mechanism can be driven by the first suspension rod to sequentially switch between the first angle position and the second angle position. Specifically, the gate locking mechanism includes a rack 14, a gear 21, a limit block 19 and a reset spring 18. The rack 14 is horizontally slidably installed on the gate 3, and the gear 21 is correspondingly installed on the second suspension rod on the gate 3 through a one-way bearing 13. A wedge block 20 is provided on one side of the rack 14, one end of which abuts against the reset spring 18. The limit block 19 is used to limit the moving distance of the rack 14.

[0041] When the hanging beam 1 is separated from the first gate 3, it moves toward the backwater side in a direction perpendicular to the gate 3 under the drive of the trolley, and the first suspension rod is just located above the wedge block 20. When the first suspension rod descends and contacts the wedge block 20, it drives the rack 14 to move to the position limited by the limit block 19. In this process, the second suspension rod rotates 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 reset spring 18, but because a one-way gear 21 is provided between the gear 21 and the second suspension rod and there is friction resistance between the second suspension rod, the second suspension rod will not rotate with the one-way gear 21 and remain at the first angle position.

[0042] Embodiment 2: The present invention also provides a mechanical linkage method for hanging and removing the gate 3, including a beam hanging operation and a beam removing operation; like Fig.12As shown, during the beam hanging operation, since the last gate section 3 does not have the second hanging assembly 9, there are two situations for hanging the beam. One is to hang the beam on the last gate section 3, and the hanging beam 1 starts to descend from the initial height H1 under the drive of the hoist. During this process, the double-toothed sleeve 24 cooperates with the lower sleeve 26, and the first suspension rod is at the first angle position. Fig.13 As shown, when the hanging beam 1 drops to the first height H2, the bottom hook of the first hanging rod at the first angle position passes through the gate ear plate through hole 4 and drops to the limit position, which is determined by the top surface of the positioning plate 27 on the last section of the gate 3. Fig.14 As shown, at this time, the hanging beam 1 is controlled to continue to descend to the second height H3. During this process, the double-toothed sleeve 24 is separated from the lower sleeve 26 and cooperates with the upper sleeve 23, so that the first suspension rod rotates to the second angle position under the cooperation of the saw teeth, and the rotation angle is 45°. At this time, the hanging beam 1 does not descend any more. Fig.15 As shown, the gate hoist controls the hanging beam 1 to rise to the third height H4. At this time, the double-toothed sleeve 24 disengages from the upper sleeve 23 and cooperates with the lower sleeve 26 again, so that the first suspension rod is rotated to the third angle position again. At this time, the first suspension rod is hooked with the ear plate 7 of the gate section 3 to complete the beam hanging operation.

[0043] The other is to perform the beam hanging operation on the remaining gates 3. The process is roughly the same, except that when the bottom hook of the first hanging rod passes through the gate ear plate through hole 4 and descends to the limit position, the limit position is determined by the top of the second hanging rod on the gate 3 after forming a connection. In other words, the second hanging rod will also descend to the limit position under the pressure of the first hanging rod, and at this time, the first hanging rod will no longer continue to descend and also reach the limit position. After that, the first hanging rod is hooked with the ear plate 7 of the gate 3 through the same operation to complete the beam hanging operation.

[0044] During the beam removal operation, the process is similar to that of the hanging beam. Driven by the hoist, the hanging beam 1 drops to the first height H2, and the first suspension rod at the third angle position drops to the limit position. At this time, the hanging beam 1 is continued to be controlled to drop to the second height H3, and the double-toothed sleeve 24 is separated from the lower sleeve 26 and cooperates with the upper sleeve 23, thereby driving the first suspension rod to rotate to the second angle position. Then the hanging beam 1 is controlled to rise to the third height H4, and the double-toothed sleeve 24 is separated from the upper sleeve 23 and cooperates with the lower sleeve 26, thereby driving the first suspension rod to rotate to the first angle position. Then the hanging beam 1 is continued to be controlled to rise, and the bottom hook body of the first suspension rod is separated from the ear plate 7, completing the beam removal operation.

[0045] In the above operation, the initial angle positions of the first and second suspension rods are both the first angle positions, so that the bottom hooks of both can pass through the corresponding gate ear plate through holes 4. After the first suspension rod and the second suspension rod are docked and circumferentially connected, the two are rotated together at the same angle, so that the second suspension rod is hooked or unhooked with the ear plate 7 of the gate 3 below. In other words, when the first suspension rod is rotated to any angle position, the second suspension rod is also rotated to the angle position.

[0046] When installing the gate 3, the steps of installing the hanging beam operation and the removing beam operation are to install each gate 3 in the gate slot of the gate 3, and water blocking can be achieved when all the gates 3 are installed. However, when it is necessary to open the gate, the first hanging rod is used to hook the uppermost gate 3 according to the steps of the hanging beam operation. In this process, all the second hanging rods also rotate with the first hanging rod to hook the upper and lower gates 3. At this time, the hanging and removing beam 1 is lifted up, so that all the gates 3 can be lifted to open the gate and release water.

[0047] It should be noted that when two adjacent gates 3 each provided with the second hook-and-release assembly 9 are installed section by section, since the lower gate 3 has completed the beam removal operation, its second suspension rod is at the first angle position, and before the upper gate 3 is disconnected from the hook-and-release beam, the second suspension rod on the upper gate 3 is at the second angle position, so 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 hook-and-release beam, the second suspension rod on the upper gate 3 is at the first angle 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 installed in this way in sequence.

[0048] It should also be noted that when the gate 3 is lifted as a whole, of the two adjacent gate sections, the upper gate section 3 is first subjected to the pulling force of the gate hoist relative to the lower gate section 3, and at the same time, because the second suspension rod will drop relative to the gate section 3 when lifting, a gap of the same spacing is generated between the two gate sections 3. In other words, when opening the gate, the load first borne by the gate hoist is only the weight of the first gate section, and 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, the gate opening operation after adopting this structure can greatly reduce the initial instantaneous load of the gate hoist, which helps to extend the service life of the gate hoist. On the other hand, due to the gap between the two upper sections of the gate when the gate is opened, the water on the water-facing side of the gate flows through the gap to the water-receiving side of the gate. This will reduce the pressure difference on both sides of the lower sections of the gate, improve the stress condition of the gate, reduce the deformation of the gate, and help extend the service life of the gate. At the same time, the reduction in pressure difference also means that the opening and closing force provided by the gate hoist is also reduced, making it easier to lift the gate.

[0049] When it is necessary to take the gate 3 out of the gate slot, it can be lifted up to the gate slot after the gate opening operation. After being transferred to other places, the gate 3 is taken off the beam and put into storage.

[0050] Due to the use of a locking mechanism, each gate section can be lifted up and fixed to one side of the slot top or the gate door when opening the gate. This method requires lower power for the gate hoist, and as each gate section is lifted up, the water pressure on the lower gate is more balanced, which helps to achieve hydrostatic balance, reduce gate deformation, and help extend the service life of the gate.
