Description

Technical Field

[0001] The present invention belongs to the technical field of overhead crane handling systems, and in particular relates to a track docking unlocking mechanism, a docking mechanism and a method applied to an intelligent production line. Background Art

[0002] As my country's semiconductor technology continues to advance, system integrators need to continuously improve production efficiency and reduce costs to adapt to technological development. Overhead crane handling system (OHT) is an important automatic handling system in semiconductor manufacturing plants. It can improve material transportation efficiency, reduce labor costs, reduce workshop space occupancy, and correspondingly reduce product contamination rate, in order to fundamentally improve the overall production process.

[0003] The early lifting mechanism used aluminum alloy profiles as the structural frame, metal sheet metal parts as the connecting parts, vertical guide rails as the guiding mechanism, and the driving mechanism drove the chain as the lifting power to drive the hoist up along the guide rails. The advantages of this mechanism are firmness and stability, and the linear guide rail can withstand radial impact force, but its structural redundancy consumes a lot of design, production and installation costs, occupies space and reduces workshop utilization, and will gradually be eliminated by the development needs of high-utilization workshops.

[0004] The latest solution is to use a belt winch to lift the OHT trolley, cancel all ground fixing mechanisms, place the drive motor on the roof, use one drive motor to control multiple winches, place the OHT trolley in the lifting vehicle, extend four belts from the winch wheel and fix them at the four corners of the lifting vehicle respectively, the motor rotates to control the belt to drive the lifting vehicle to rise slowly, when the track in the lifting vehicle is level with the aerial track, the OHT trolley in the lifting vehicle can be driven into the aerial track.

[0005] In order to ensure that the track of the lifting vehicle can be leveled with the aerial track, the conventional method is to set a pin at one end of the aerial track and a socket on the track side of the lifting vehicle. When the lifting vehicle is lifted to the desired height, as long as the pin of the aerial track can be inserted into the socket of the lifting vehicle track, the track on both sides can be leveled. However, due to the reduced rigidity of the lifting vehicle, it was found in actual use that the lifting vehicle carrying the OHT trolley is prone to swinging, and the root of the pin cannot be inserted, so the lifting vehicle cannot be connected to the aerial track.

[0036] Based on the same concept, the present invention also provides a rail docking unlocking method, including the above-mentioned rail docking unlocking mechanism applied to the intelligent production line, including:

[0037] S1: driving the second track to rise, driving the fixed docking assembly to move toward the first accommodating space;

[0038] S2: the docking member of the fixed docking assembly moves along the first track in the first accommodating space, driving the elastic body to retract out of the first accommodating space, and then the docking member protrudes out of the first accommodating space;

[0045] When the elastic body is reset, the docking piece is separated from the locking section, so that the unlocking piece and the docking piece are moved to the bottom of the elastic body to realize unlocking.

[0046] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art:

[0047] 1. When the docking piece of the present invention moves toward the elastic body, the elastic body drives the docking piece to contract by contacting the docking piece, so that the docking piece moves to the side of the elastic body away from the second track, and then the elastic body resets and extends into the first accommodating space and limits the docking piece in the locking section to achieve docking and fixation of the first track and the second track. The docking piece moves to the side of the elastic body away from the second track and then docks, which can prevent docking failure caused by the second track retreating. Because if the docking piece is docked before moving to the side of the elastic body away from the second track, it is easy to cause docking failure when the second track retreats. However, the docking piece of the present invention moves to the side of the elastic body away from the second track and then docks, so that when the second track retreats, the elastic body is stressed and docking failure will not occur.

[0048] 2. After the docking piece of the present invention moves to the side of the elastic body away from the second track, the second track is controlled to move in the opposite direction to drive the docking piece and the elastic body to dock, so that the docking piece and the elastic body can be docked more smoothly and ensure a firm docking.

[0049] 3. The first track of the present invention is an aerial track, and the second track is a lifting track. In this way, when the docking piece moves to the side of the elastic body away from the second track, that is, the docking piece moves to the top of the elastic body, the elastic body can carry the docking piece after docking, thereby achieving the anti-falling purpose of the lifting track.

[0050] 4. The lifting rail of the present invention is raised and lowered by a suspended lifting device, which can reduce costs. When the lifting rail is lifted and docked, the height of the docking surface of the lifting rail exceeds the aerial rail, and then the lifting rail is lowered and dropped onto the elastomer. In this way, even if the lifting rail is slightly uneven during the lifting process, when each side of the lifting rail falls on the elastomer one after another, it can be ensured that the lifting rail and the aerial rail are docked evenly. And during docking, the docking piece is located above the elastomer, that is, the docking piece is pressed on the elastomer. Even if the suspended lifting device loses control and fails to hold the lifting rail, the lifting rail will be carried by the elastomer and will not fall, ensuring safety and achieving secondary fall prevention. At the same time, even if the lifting rail is not level and swings before it is in place, the lifting rail and the aerial rail can be docked horizontally by lowering the docking piece and cooperating with the elastomer, achieving anti-swing docking.

[0051] 5. The fixed docking assembly of the present invention includes an unlocking member. When the unlocking member moves toward the first track, it contacts with the elastic body and drives the elastic body to contract, so that the unlocking member moves to the side of the elastic body away from the second track; after the elastic body is reset, the unlocking member moves in the opposite direction away from the first track, and the unlocking member contacts with the elastic body again, and moves relative to the jacking column to abut against the docking member through the reaction force given by the elastic body. After abutment, the unlocking member drives the elastic body to contract, so that the unlocking member and the docking member move to the side of the elastic body close to the second track to achieve unlocking. In other words, the unlocking function can be achieved by driving the unlocking member through the suspended lifting device, so that there is no need to set up an additional unlocking drive mechanism, making the structure simpler, and when unlocking, the lifting track needs to be moved upward first, avoiding the sudden drop of the lifting track caused by misunderstanding the lock.

[0072] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and use inaccurate ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0073] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0074] The core of the present invention is to provide a track docking and unlocking mechanism for intelligent production lines, including a movable docking assembly 200 and a fixed docking assembly 100, wherein the movable docking assembly 200 is connected to the first track, and the fixed docking assembly 100 is connected to the second track, and the movable docking assembly 200 and the fixed docking assembly 100 cooperate with each other to realize the change between the first track and the second track between the docking fixed mode and the unlocking mode;

[0075] The movable docking assembly 200 further includes at least one pair of first docking assembly 21 and second docking assembly 22 arranged opposite to each other, a first accommodation space 202 is formed between the first docking assembly 21 and the second docking assembly 22, and at least one elastic body 24 is arranged on the first docking assembly 21 and the second docking assembly 22;

[0076] The fixed docking assembly 100 includes a docking member 102 and an unlocking member 104. The fixed docking assembly 100 is configured to move along a first track in the first accommodation space 202, driving the elastic body 24 to extend into or retract out of the first accommodation space 202.

[0077] The first track includes an unlocking section and a locking section. In the docking and fixing mode, the elastic body 24 can extend into the first accommodating space 202 and limit the docking member 102 in the locking section to achieve docking and fixing of the first track and the second track. In the unlocking mode, the unlocking member 104 is configured to drive the elastic body 24 to retract out of the first accommodating space 202 in the unlocking section to make the docking member 102 disengage from the locking section to unlock the first track and the second track.

[0078] During the material transportation process, the first track and the second track need to be able to work in a docking and fixing mode, and can also change to an unlocking mode after this mode; the seamless switching between docking and fixing and unlocking makes material handling convenient.

[0079] The core creative ideas of the present invention are respectively described below with multiple embodiments.

[0080] Example 1

[0081] See also Figure 1A , Figure 1B , Figures 2 to 16 , which is a diagram related to this embodiment. A track docking unlocking mechanism applied to an intelligent production line includes a movable docking assembly 200 and a fixed docking assembly 100.

[0082] The movable docking assembly 200 includes a fixed socket 201, a first accommodating space 202 connected along a first track direction (in this embodiment, the track direction is the radial direction of the fixed socket 201), and an accommodating hole 203 is arranged along the axial direction of the fixed socket 201. The first docking assembly 21 and the second docking assembly 22 are respectively located on opposite sides of the first accommodating space 202 in the accommodating hole 203. One end of the elastic body 24 (the elastic body 24 includes the first elastic body and / or the second elastic body) includes at least an end 25 and a spring 209. The end 25 is arranged at the proximal end of the first accommodating space 202. The compression spring 209 causes the end 25 to retract out of the first accommodating space 202, and the spring 209 is reset to cause the end 25 to extend into the first accommodating space 202. In this example, the first accommodating space 202 is a hollow large round through hole structure, please refer to Figures A and B, L 1 The diameter of the first accommodating space 202 is such that the fixed docking assembly 100 can extend into the first accommodating space 202 to move in the first track direction, and the fixed docking assembly 100 can exit the first accommodating space 202 to move in the opposite direction of the first track. The first accommodating space 202 provides an unlocking section and a locking section. The large round through hole structure of the first accommodating space 202 is only an example, and it is only necessary to provide a space for the fixed docking assembly 100 to move in the first track direction, and is not limited to a specific shape. It should also be noted that when the fixed docking assembly 100 can extend into the first accommodating space 202 to move in the first track direction, the position of the fixed docking assembly 100 above the elastic body is defined as the locking section, and the rebound of the elastic body 24 can clamp the fixed docking assembly 100 to achieve docking and fixation of the two tracks. When the fixed docking assembly 100 can exit the first accommodating space 202 to move in the opposite direction of the first track, the fixed docking assembly 100 falls below the top of the elastic body to be the unlockable section. In the figure, draw H 1 How the elastic body 24 is fixed in the fixing socket 201 and configured to be able to extend or retract into the first accommodating space 202 is a common technology, and the subsequent structure introduction is only an example and is not used to limit the present invention.

[0083] See also Figure 1B The fixed docking assembly 100 includes a docking member 102 and an unlocking member 104. The docking member 102 and the unlocking member 104 are installed on a jacking column 103.

[0084] The unlocking member 104 can be adjusted to different positions on the lifting column 103 through the adjustment structure. In this example, a cooperation spacing H is set between the docking member 102 and the unlocking member 104. 2 , collaboration distance H 2The spacing is set to be adjustable, and the side 1042 of the unlocking member close to the docking member is not smaller than the side 1022 of the docking member close to the unlocking member. In this solution, the docking member 102 adopts a cap structure that is small at the top and large at the bottom, and the unlocking member 104 adopts a cap structure that is large at the top and small at the bottom, and the bottom of the cap of the docking member 102 is the same size as the top of the cap of the unlocking member 104. In order to facilitate subsequent guidance, the docking member 102 and the unlocking member 104 respectively adopt a cone shape similar to a mirror structure.

[0085] In docking fixed mode, the coordination distance H 2 Adjust to large spacing H 大 The resetting elastic body 24 is clamped on the cooperation distance to limit the docking member 102 to the locking section.

[0086] In unlocked mode, the collaborative distance H 2 Adjust to small spacing H 小 The unlocking member 104 is configured to drive the elastic body 24 to retract out of the first accommodating space 202. When the elastic body 24 is reset, the unlocking member 104 is configured to drive the docking member 102 to leave the locking section. 大 >H 小 .

[0087] The docking member 102 and the unlocking member 104 are sequentially arranged on the jacking column 103. The unlocking member 104 can be adjusted to different positions on the jacking column 103 through an adjustment structure (such as an adjustment nut 106) to adjust the cooperation distance H. 2 size.

[0088] The docking member 102 and the unlocking member 104 are respectively provided with a groove 1021 and a protrusion 1041 that cooperate with each other. The adjustment structure can adjust the distance between the groove 1021 and the protrusion 1041 so that the docking member 102 and the unlocking member 104 fit tightly.

[0089] In this example, set H 1 >H 2 , the height of the elastic body 24 is H 1 , H 2 L is the cooperative spacing between the docking member 102 and the unlocking member 104. 4 ≥(L 2 -L 3 ) / ,L 4 is the working stroke of the first elastic body / the second elastic body, L 2 L is the maximum diameter of the cross section between the docking piece 102 and the unlocking piece 104, 3 is the radial dimension of the lifting column 103.

[0090] In this example, a cooperation distance H is set between the docking member 102 and the unlocking member 104. 2 , collaboration distance H2 The spacing is set to an adjustable size, and the first track and the second track are changed between the docking fixed mode and the unlocking mode through the above method. However, the above method is only one implementation scheme. 2 The elastic body 24 can be controlled to have a rebound force and a stroke, and the fixed docking assembly 100 can be controlled to have a movement speed in the opposite direction of the first track. Any one of the above parameters can be controlled so that when the elastic body 24 rebounds and resets, the docking member 102 of the fixed docking assembly 100 can be controlled to be separated from the locking section.

[0091] A first guiding conical surface is arranged on the elastic body 24, and a second guiding surface and a third guiding surface are arranged on the docking member 102 and the unlocking member 104 respectively. The guiding direction of the second guiding surface relative to the first guiding conical surface is adapted to the first trajectory movement direction in the docking and fixing mode, and the guiding direction of the third guiding surface relative to the first guiding conical surface is adapted to the first trajectory movement direction in the unlocking mode, and is opposite to the first trajectory movement direction in the docking and fixing mode.

[0092] When the docking member 102 of the present invention moves toward the elastic body 24, it contacts with the end 25 of the elastic body 24 and drives the elastic body 24 to contract, so that the docking member 102 moves to the side of the elastic body 24 away from the second track, and then the elastic body 24 resets and extends into the first accommodating space 202 and limits the docking member 102 in the locking section to achieve docking and fixing of the first track and the second track. The docking member 102 moves to the side of the elastic body 24 away from the second track and then docks, which can prevent docking failure caused by the second track retreating, because if the docking member 102 is docked before moving to the side of the elastic body 24 away from the second track, it is easy to cause docking failure when the second track retreats. However, the docking member 102 of the present invention moves to the side of the elastic body 24 away from the second track and then docks, so that when the second track retreats, the elastic body 24 is stressed and docking failure will not occur.

[0093] Furthermore, after the docking member 102 moves to the side of the elastic body 24 away from the second track, the second track is controlled to move in the opposite direction to drive the docking member 102 to dock with the elastic body 24, so that the docking member 102 and the elastic body 24 can be docked more smoothly and ensure a firm docking.

[0094] Specifically, in this embodiment, the second track is the lifting track 3, and the first track is the aerial track 4. When the lifting track 3 rises, it docks with the aerial track 4 through the fixed docking assembly 100 and the movable docking assembly 200. And the lifting track 3 is raised and lowered by a suspended lifting device.

[0095] In this way, when the docking piece 102 moves to the side of the elastic body 24 away from the second track, that is, the docking piece 102 moves to the top of the elastic body 24, the elastic body 24 can carry the docking piece 102 after docking, thereby achieving the purpose of preventing the lifting track 3 from falling.

[0096] Lifting by a suspended lifting device can reduce costs. The suspended lifting device can specifically be a belt winch hoist. The use of a suspended lifting device can completely eliminate the ground fixing mechanism, and the structure is simpler. However, the suspension lifting device drives the lifting track 3 to easily swing and it is difficult to achieve accurate and stable docking with the aerial track 4. The track docking unlocking mechanism of the present invention can effectively solve this problem.

[0097] When the lifting track 3 is lifted and docked, the docking surface is higher than the aerial track 4, and then the lifting track 3 is lowered and dropped onto the elastic body 24. In this way, even if the lifting track 3 is slightly uneven during the lifting process, when each side of the lifting track 3 falls on the elastic body 24 one after another, it can ensure that the lifting track 3 and the aerial track 4 are smoothly docked. When docking, the docking piece 102 is located above the elastic body 24, that is, the docking piece 102 is pressed on the elastic body 24. Even if the suspended lifting device loses control and does not pull the lifting track 3, the lifting track 3 will be carried by the elastic body 24 and will not fall, ensuring safety and achieving secondary anti-falling. At the same time, even if the lifting track 3 is not horizontal and swings before it is in place, the lifting track 3 can be horizontally docked with the aerial track 4 by lowering the docking piece 102 and cooperating with the elastic body 24, achieving anti-swing docking.

[0098] Specifically, the lower end of the docking member 102 is provided with a docking portion, and the upper end of the end 25 of the elastic body 24 is provided with a docking matching portion, and in this embodiment, the docking portion is the first positioning surface 109, and the docking matching portion is the second positioning surface 216. When the first positioning surface 109 is lowered and matched with the second positioning surface 216, the lifting track 3 and the aerial track 4 can be accurately docked on the same horizontal plane, and the surface matching can not only achieve accurate positioning docking of the lifting track 3 and the aerial track 4, but also prevent the lifting track 3 from shaking after docking.

[0099] The fixed docking assembly 100 also includes a mounting member and an unlocking member 104. The mounting member is connected to the lifting track 3. The docking member 102 is fixed on the mounting member. The unlocking member 104 is movably connected to the mounting member and is located on the side of the docking member 102 away from the aerial track 4. The unlocking member 104 is spaced apart from the docking member 102 and can move toward or away from the docking member 102.

[0100] When the unlocking member 104 moves toward the aerial track 4, it contacts with the end head 25 to drive the elastic body 24 to contract, so that the unlocking member 104 moves to the side of the elastic body 24 away from the lifting track 3; after the elastic body 24 is reset, the unlocking member 104 moves in the opposite direction away from the aerial track 4, and the unlocking member 104 contacts with the end head 25 again, and moves relative to the mounting member through the reaction force given by the end head 25 to abut against the docking member 102. After the abutment, the unlocking member 104 drives the elastic body 24 to contract, so that the unlocking member 104 and the docking member 102 move to the side of the elastic body 24 close to the lifting track 3 to achieve unlocking.

[0101] That is to say, the unlocking function can be achieved by driving the unlocking member 104 through the suspended lifting device, so that there is no need to set up an additional unlocking drive mechanism, which makes the structure simpler. When unlocking, the lifting track 3 needs to be moved upward first, avoiding the sudden drop of the lifting track 3 caused by misunderstanding the lock.

[0102] Furthermore, the lifting column 103 is arranged on the mounting member, the docking member 102 is fixedly arranged on the top of the lifting column 103, and the unlocking member 104 is sleeved and slidably connected to the lifting column 103. A connecting seat 105 is provided on the mounting member, the lifting column 103 is mounted on the connecting seat 105, and a waist-shaped hole is provided on the connecting seat 105 in the direction toward or away from the lifting track 3. The connecting seat 105 is adjustably connected to the mounting member through the waist-shaped hole, that is, the positions of the docking member 102 and the unlocking member 104 can be adjusted through the waist-shaped hole of the connecting seat 105 to improve the error tolerance rate and reduce the design and manufacturing cost.

[0103] The lifting column 103 is threadedly connected with an adjusting nut 106 below the unlocking member 104 , and the adjusting nut 106 is used to adjust the lower limit position of the unlocking member 104 .

[0104] Specifically, the first guide cone surface is provided at the end 25 of the elastic body 24 facing the lower end of the lifting track 3, and the second guide surface is provided at the upper end of the docking member 102 facing the aerial track 4. The docking member 102 drives the elastic body 24 to contract through the first guide cone surface and the second guide surface. The third guide surface is provided at the lower end of the unlocking member 104 away from the aerial track 4. When the unlocking member 104 moves upward toward the aerial track 4, the elastic body 24 is driven to contract through the first guide cone surface. When the unlocking member 104 moves downward in the opposite direction away from the aerial track 4, the elastic body 24 is driven to contract through the third guide surface.

[0105] In this embodiment, the first guiding conical surface is the downwardly inclined guiding conical surface 205, the second guiding surface is the second guiding conical surface 108, and the second guiding conical surface 108 is the circumferential side wall of the docking member 102 that contracts upward; the third guiding surface is the first guiding conical surface 107, and the first guiding conical surface 107 is the circumferential side wall of the unlocking member 104 that contracts downward.

[0106] The elastomer 24 is configured to switch between a locked state and an unlocked state; when in the locked state, the elastomer 24 is in an elastically extended state and the end 25 is located on the moving path of the docking member 102 and the unlocking member 104; when in the unlocked state, the elastomer 24 is in an elastically contracted state and the end 25 leaves the moving path of the docking member 102 and the unlocking member 104.

[0107] It also includes a detection component for detecting whether the elastic body 24 is in a locked state and an unlocked state, that is, whether the detection mechanism is in a docking fixed mode or an unlocking mode, so as to achieve the purpose of controlling the action of the suspended lifting device to achieve automatic docking and unlocking.

[0108] The movable docking assembly 200 also includes a fixed socket 201, a socket corresponding to the docking member 102 is provided in the middle of the fixed socket 201, and the socket is a first accommodation space 202 arranged along the first track direction. A accommodating hole 203 connected to the socket is provided on the side of the fixed socket 201, and an elastic body 24 is arranged in the accommodating hole 203, and one end of the elastic body 24 extends into the socket and is located on the lifting and moving path of the docking member 102 and the unlocking member 104. When the docking member 102 moves upward, it enters the socket and cooperates with the elastic body 24. In this embodiment, an elastic body 24 is arranged on each side of the socket, and of course, other numbers can be used in other embodiments, which is not limited in this embodiment.

[0109] The elastic body 24 includes an end 25, a positioning pin 204 and a spring 209. The end 25 is arranged on the positioning pin 204. The side of the accommodating hole 203 away from the socket passes through the fixed socket 201. The positioning pin 204 is penetrated in the accommodating hole 203, and the side of the positioning pin 204 close to the socket extends into the socket and the side away from the socket extends out of the accommodating hole 203. The end of the end 25 is the end of the positioning pin 204 close to the socket.

[0110] A cover 210 is provided on the outer end surface of the fixed socket 201 away from the socket, and a through hole corresponding to the accommodating hole 203 is provided on the cover 210. The diameter of the through hole is smaller than the accommodating hole 203. The positioning pin 204 is passed through the through hole, and the part of the positioning pin 204 extending out of the accommodating hole 203 and the through hole is provided with a limiting flange 207. The size of the limiting flange 207 is larger than the through hole. The limiting flange 207 is used to limit the extreme position of the positioning pin 204 moving toward the socket.

[0111] The spring 209 is sleeved on the positioning pin 204 and located in the accommodating hole 203. The end of the end 25 facing the positioning pin 204 is provided with a supporting step 206. One end of the spring 209 supports the supporting step 206 and the other end supports the cover 210. The spring 209 gives the positioning pin 204 an elastic force to move toward the insertion hole.

[0112] A stop surface 208 is provided on the side of the limiting flange 207, and a stop piece 211 is provided on the outer end surface of the fixed socket 201 away from the socket, and the stop piece 211 is attached to the stop surface 208. The cooperation between the stop piece 211 and the stop surface 208 can prevent the positioning pin 204 from rotating, making locking and unlocking more stable.

[0113] The detection assembly includes a first sensor 213 and a second sensor 214, and the first sensor 213 / the second sensor 214 are respectively used to detect whether the positioning pin 204 is in two positions close to the plug hole and far away from the plug hole, so as to detect whether the elastic body 24 is in a locked state and an unlocked state. For example, the first sensor and the second sensor are respectively arranged at positions close to the two outer end surfaces of the fixed socket, and the first sensor / the second sensor are used to detect whether the end is in a state of a near end or a state of a far end position of the first accommodating space, so as to detect whether the elastic body limits the docking piece in the locking section, or detects whether the docking piece is separated from the locking section.

[0114] Furthermore, a detection sheet 215 is provided on the end surface of the positioning pin 204 extending out of one side of the accommodating hole 203, and the first sensor 213 and the second sensor 214 are triggered by the detection sheet 215. The first sensor 213 and the second sensor 214 are both photoelectric sensors, and the first sensor / the second sensor is triggered by the detection sheet 215 to confirm that the end is in the distal end state of the first accommodating space.

For example, the movable docking assembly 200 further includes two pairs of first docking assemblies 21 and second docking assemblies 22 arranged opposite to each other, each pair includes the first docking assemblies 21 and the second docking assemblies 22 arranged opposite to each other, and in this way, when the objects that can be docked by the fixed docking assembly 100 are relatively heavy or require relatively stable docking, multiple sets of first docking assemblies 21 and second docking assemblies 22 arranged opposite to each other can improve the docking accuracy and stability.

[0117] Example 3

[0118] Only one elastic body 24 may be provided on the first docking assembly 21 and the second docking assembly 22. As long as the elastic body 24 can hold and fix the docking assembly 100 and the objects hung thereon, this method is simple to implement and is suitable for lightweight track docking.

[0129] Example 5

[0130] The method for achieving docking of the above-mentioned mechanism further comprises:

[0131] S1: driving the second track to rise, driving the fixed docking assembly 100 to move toward the first accommodating space 202;

[0132] S2: the docking member 102 of the fixed docking assembly 100 moves along the first track in the first accommodation space 202, driving the elastic body 24 to retract out of the first accommodation space 202, and then the docking member 102 protrudes out of the first accommodation space 202;

[0133] S3: The elastic body 24 is reset and extends into the first accommodating space 202, and the positioning docking member 102 is limited in the locking section to achieve docking and fixing of the first track and the second track;

[0134] S4: In the unlocking mode, the unlocking member 104 of the fixed docking assembly 100 drives the elastic body 24 to retract out of the first accommodating space 202 in the unlocking section so that the docking member 102 is separated from the locking section to unlock the first track and the second track.

[0139] When the elastic body 24 is reset, the docking member 102 is separated from the locking section, so that the unlocking member 104 and the docking member 102 move to the bottom of the elastic body 24 to achieve unlocking.

[0140] In reality,

[0141] S1: During docking, the lifting track 3 is first driven upward by the suspended lifting device. Before the lifting track 3 is in place, the docking piece 102 is inserted into the socket on the fixed socket 201, and the second guide cone surface 108 of the docking piece 102 contacts the guide slope 205 of the positioning pin 204. The docking piece 102 drives the end head 25 to overcome the elastic force of the spring 209 and move away from the socket, so that the end head 25 leaves the moving path of the docking piece 102 and the unlocking piece 104, until the docking piece 102 rises to above the end head 25.

[0142] S2: After the docking member 102 rises to the top of the end head 25, the end head 25 is reset from the extreme position away from the socket by the elastic force of the spring 209, so that the end head 25 enters between the docking member 102 and the unlocking member 104. When the positioning pin 204 moves from the extreme position away from the socket to the extreme position close to the socket, it is detected by the second sensor 214 and the first sensor 213 in sequence, so as to provide feedback to the suspended lifting device, and the suspended lifting device reversely drives the lifting track 3 to descend, so that the first positioning surface 109 at the lower end of the docking member 102 abuts against the second positioning surface 216 at the upper end of the end head 25, so as to achieve the docking of the lifting track 3 and the aerial track 4, and the docking member 102 is carried on the end head 25. At the same time, since the positioning pin 204 is located at the extreme position close to the socket, it is detected by the first sensor 213, and feedback can also be provided that the docking is completed.

[0143] S3: When unlocking, the lifting track 3 is first driven to rise by the suspended lifting device, and the unlocking member 104 contacts the guiding slope 205 of the end head 25 and drives the end head 25 to overcome the elastic force of the spring 209 and move away from the socket until the unlocking member 104 rises above the end head 25.

[0144] S4: After the unlocking member 104 rises to the top of the end head 25, the end head 25 is reset from the extreme position away from the insertion hole by the elastic force of the spring 209, so that the end head 25 enters the bottom of the unlocking member 104. When the positioning pin 204 moves from the extreme position away from the insertion hole to the extreme position close to the insertion hole, it is detected by the second sensor 214 and the first sensor 213 in sequence, so as to feedback to the suspended lifting device, and the suspended lifting device reversely drives the lifting track 3 to descend, and the unlocking member 104 abuts against the end head 25. The unlocking member 104 moves relative to the jacking column 103 to abut against the docking member 102 by the reaction force given by the end head 25. After the abutment, the unlocking member 104 drives the end head 25 to overcome the elastic force of the spring 209 and move away from the insertion hole, so that the unlocking member 104 and the docking member 102 move to the bottom of the end head 25 to achieve unlocking. After unlocking, the rear end head 25 is reset by elastic force, and the positioning pin 204 is detected by the second sensor 214 and the first sensor 213 in sequence when it moves from the extreme position far away from the insertion hole to the extreme position close to the insertion hole, and feedback is given that the unlocking is completed.

[0145] Application Examples

When the suspended lifting device drives the lifting track 3 to dock with the aerial track 4, the overhead crane can move from the lifting vehicle 5 to the aerial track 4.

[0147] The lifting vehicle 5 is a structural frame made of aluminum alloy profiles. In this embodiment, the suspended lifting device is a belt winch hoist. The winch wheel of the belt winch hoist extends four belts and is respectively fixed on the four corners of the lifting vehicle 5. The motor rotates to control the belt to drive the lifting vehicle 5 to rise slowly. When the lifting track 3 in the lifting vehicle 5 is connected to the aerial track 4 and is level, the overhead crane in the lifting vehicle 5 can be driven into the aerial track 4.

[0148] The mounting parts of the fixed docking assembly 100 are installed in the groove of the aluminum alloy profile of the lifting carrier 5 by T-bolts. This installation method can realize the position adjustment of the mounting parts along the length direction of the lifting track 3 to improve the error tolerance and reduce the design and manufacturing cost.

[0149] The present invention can realize the anti-swing docking of the lifting track 3 on the lifting vehicle 5 and the aerial track 4, and has the following advantages:

[0150] 1. Precise docking: When the first positioning surface 109 descends and cooperates with the second positioning surface 216, the lifting track 3 and the aerial track 4 can be precisely docked at the same level to ensure that the overhead crane can smoothly drive out of the lifting vehicle 5.

[0151] 2. Secondary anti-falling: Since the docking piece 102 is located above the positioning pin 204 during docking, that is, the docking piece 102 is pressed on the positioning pin 204, even if the suspended lifting device loses control and fails to hold the lifting vehicle 5, the lifting vehicle 5 will be supported by the positioning pin 204 and will not fall, thereby ensuring the safety of the overhead crane.

[0152] 3. Anti-swing docking: Even if the lifting vehicle 5 is not level and swings before it is in place, the lifting track 3 on the lifting vehicle 5 can be horizontally docked with the aerial track 4 by lowering the first positioning surface 109 and cooperating with the second positioning surface 216.

[0153] 4. Low cost: The push-pull movement of the positioning pin 204 does not require power supply, while the movement of the positioning pin 204 in similar mechanisms is driven by a motor. The present invention has a cost advantage. In addition, the installation, debugging and maintenance of the mechanism that does not require power supply are also safer.

[0154] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments.
