Description

Technical Field

[0001] The utility model relates to the technical field of overhead crane tracks, and in particular to a smoke shielding structure of an overhead crane track which has a simple overall structure, low installation cost, and has real-time action and shielding integrity in times of danger. Background Art

[0002] The fire and smoke doors currently installed are mainly installed at the entrances and exits of buildings. If it is a large building with several spaces inside, it is installed at the entrances and exits of two adjacent spaces. When a fire occurs, the detection system is activated due to the thick smoke, and the fire and smoke doors are activated and deployed downward, and the entrances and exits are closed through the fire and smoke doors. However, for the fire prevention effect, such fire and smoke doors are basically designed to be very heavy, and the manufacturing cost is relatively high.

[0003] As for fire prevention in semiconductor factories, the fire prevention on the ground is not much different from that in general buildings, but there are often overhead hoist transfer (OHT) systems in factories. This aerial unmanned transport vehicle, commonly known as a crane, can effectively utilize the three-dimensional space of the factory for transportation. However, the smoke and fire prevention system of the crane is difficult to implement in actual use, and there are the following problems and defects that need to be improved:

[0004] First, the ceiling height of a semiconductor factory is no less than 4 to 5 meters, while the common fire door size is only about 2 meters high. If this is used to prevent smoke and fire in the factory, the modification cost will be considerable.

[0005] Secondly, the thickness of common fire doors ranges from about 5 cm to 12 cm, and the overhead travelling track must be a continuous track on the ceiling. Even at the turning or connecting points, there will not be 5 cm to 12 cm of space for users to install fire doors, so it is difficult to free up space in the middle of the track to install fire doors.

[0006] Third, the fire and smoke protection of overhead cranes can usually only be provided by rolling doors above the tracks or by fire doors below the tracks. As a result, thick smoke and flames can easily burst out from the uncovered tracks, and the fire and smoke protection effects do not comply with regulations.

[0007] Therefore, there is an urgent need to provide a smoke shielding structure for an overhead travelling vehicle track to solve the above problems. Utility Model Content

[0008] The utility model aims to provide a smoke shielding structure for an overhead crane track. By utilizing the gap design of the overhead crane track, a vertical wall mechanism for smoke protection can easily pass through the overhead crane track for shielding. By utilizing the design of electromagnetic positioning parts and elastic components, in conjunction with a control device and a smoke sensing component, both the setting cost and the real-time performance of the action can be taken into account.

[0009] To achieve this purpose, the utility model adopts the following technical solutions:

[0010] A smoke shielding structure for an overhead crane track, comprising:

[0011] One day car track;

[0012] A gap portion is formed on the overhead travelling vehicle track;

[0013] A vertical wall guide rail, disposed above the gap portion;

[0014] A vertical wall mechanism, movably disposed on the vertical wall guide rail, and movable between an open position and a closed position;

[0015] A movable fixing member, disposed in the vertical wall guide rail and fixed to one end of the vertical wall mechanism;

[0016] an electromagnetic positioning member, disposed on the vertical wall guide rail adjacent to the opening position and used for positioning the movable fixing member;

[0017] An elastic component, disposed on the vertical wall guide rail adjacent to the closed position;

[0018] A traction assembly, disposed between the movable fixing member and the elastic assembly;

[0019] a control device electrically connected to the electromagnetic positioning element; and

[0020] At least one smoke sensing component is connected to the control device so as to send a warning signal to the control device when smoke is detected, so that the electromagnetic positioning component releases the movable fixing component.

[0021] As an optional solution, the vertical wall mechanism has a plurality of shielding sheets and a plurality of connecting parts arranged between the shielding sheets, so that the shielding sheets are connected and folded by the connecting parts.

[0022] As an optional solution, the overhead travelling vehicle track has a plurality of chamfered portions at a side adjacent to the gap portion.

[0023] As an optional solution, the vertical wall mechanism has a yielding portion whose position corresponds to the gap portion, and the thickness of the yielding portion is smaller than the thickness of the vertical wall mechanism.

[0024] As an optional solution, the movable fixing member has a magnetic body and a plurality of pulleys arranged on one side of the magnetic body.

[0025] As an optional solution, at least one proximity sensing component connected to the control device is provided on one side of the overhead crane track adjacent to the vertical wall mechanism. When the vertical wall mechanism is in the closed position and the proximity sensing component detects the overhead crane, a warning signal is sent to the control device to stop the overhead crane from moving.

[0026] As an optional solution, the elastic component is a spiral spring.

[0027] As an optional solution, the traction component is a steel cable.

[0028] Beneficial effects of the utility model:

[0029] The overhead crane track smoke shielding structure provided by the utility model uses an electromagnetic positioning member to absorb the movable fixing member in normal times, so that the vertical wall mechanism is positioned in the open position. When the smoke sensing component detects smoke, the control device automatically releases the electromagnetic positioning member, so that the vertical wall mechanism is pulled by the elastic component and the traction component is pulled along the vertical wall guide rail to pass through the gap portion, so that the overhead crane track is isolated from the gap portion by the vertical wall mechanism to shield the smoke, thereby achieving real-time and complete shielding action, and the overall structure is simple and the cost is low. Through the above technology, the problems of the smoke and fire protection system of the general overhead crane, such as high production cost, difficulty in freeing up space in the middle of the track to set up a fire door, and thick smoke and flames easily bursting out from the track that is not shielded, can be overcome, and the practical progress of the above advantages can be achieved.

[0044] refer to Figure 1 FIG. 1 is a perspective view of a smoke shielding structure for a crane track provided in a first preferred embodiment of the present invention. It can be clearly seen from the figure that the present invention provides a smoke shielding structure for a crane track, including:

[0045] One day car track 1;

[0046] A gap portion 11 is formed on the overhead travelling vehicle track 1;

[0047] A vertical wall guide rail 2, disposed above the gap portion 11;

[0048] A vertical wall mechanism 3 is movably disposed on the vertical wall guide rail 2 and moves between an open position and a closed position;

[0049] A movable fixing member 4 is disposed in the vertical wall guide rail 2 and fixed to one end of the vertical wall mechanism 3;

[0050] An electromagnetic positioning member 5, disposed near the opening position of the vertical wall guide rail 2, and used to position the movable fixing member 4;

[0051] An elastic component 6 is disposed near the closed position of the vertical wall guide rail 2;

[0052] A traction assembly 7, disposed between the movable fixing member 4 and the elastic assembly 6;

[0053] a control device 8 electrically connected to the electromagnetic positioning member 5; and

[0054] At least one smoke sensing component 81 is connected to the control device 8 so as to send a warning signal to the control device 8 when smoke is detected, so that the electromagnetic positioning component 5 releases the movable fixing component 4.

[0055] The overhead crane track 1 is used for a double-track overhead crane 9, the vertical wall guide rail 2 is laterally placed above the gap 11, the vertical wall mechanism 3 is a suspended curtain, the electromagnetic positioning member 5 is an electromagnetic buckle, the movable fixing member 4 is one of a metal fixing block or a magnetic fixing block, the elastic component 6 is a volute spring, the traction component 7 is a steel cable, the control device 8 is a server or a computer, and the electromagnetic positioning member 5 is connected to the information by wire or wireless means, and the smoke sensing component 81 is a photoelectric smoke detector as an example, and can be set at any position in the semiconductor plant. The corresponding forms of the above structures are only examples of preferred embodiments, and all structures with the same function belong to the scope of this application and are not limited to the above examples.

[0056] Through the above description, the structure of the present technology can be understood, and according to the corresponding coordination of this structure, the overall structure can be simple, the installation cost is low, and it has the advantages of real-time action and shielding integrity in times of crisis. The detailed explanation will be described below.

[0057] At the same time with reference Figures 1 to 3 As shown, it is a three-dimensional perspective view and an action schematic diagram of the smoke shielding structure of the overhead crane track provided in the first preferred embodiment of the present application. Through the above-mentioned arrangement, when no disaster occurs, the movable fixing member 4 is attracted by supplying power to the electromagnetic positioning member 5, so that the vertical wall mechanism 3 is positioned in the open position. At this time, the use of the overhead crane track 1 is no different from a general overhead transport system.

[0058] When the smoke sensing component 81 detects smoke, in addition to sending out an alarm, it also sends out a warning signal to the control device 8. After receiving the warning signal, the control device 8 automatically sends out a control signal to the electromagnetic positioning member 5. The control signal can actually be a power-off action, so that the electromagnetic positioning member 5 releases the positioning action on the movable fixing member 4 due to the loss of power. At this time, the traction component 7 fixedly connected to the movable fixing member 4 is pulled by the elastic force of the elastic component 6. At the moment when the electromagnetic positioning member 5 is released from the fixation, the vertical wall mechanism 3 moves laterally along the vertical wall guide rail 2 along with the movable fixing member 4, and passes through the gap 11 of the overhead crane track 1, and completes the smoke shielding action of the overhead crane track 1 on both sides of the gap 11, and can even abut against the wall or other fire doors on the ground to form a smoke-proof wall extending from the ground to the ceiling. Therefore, the overall structure of this embodiment is simple, the setting cost is low, the protection action is more timely, and the overhead crane track 1 is effectively shielded to take into account the normal use of the overhead crane 9 and the safety in times of distress.

[0059] At the same time with reference Figure 4, which is a schematic diagram of the structure of the yielding portion provided in the second preferred embodiment of the present application, it can be clearly seen from the figure that the present embodiment is similar to the above embodiment, the only difference being that the vertical wall mechanism 3 has a yielding portion 31 corresponding to the gap portion 11, and the thickness of the yielding portion 31 is less than the thickness of the vertical wall mechanism 3. Through the design of the yielding portion 31, the vertical wall mechanism 3 can pass through the gap portion 11 more easily, which can reduce the risk of the vertical wall mechanism 3 rubbing against the overhead travelling vehicle track 1, or can reduce the width of the gap portion 11, so that when the overhead travelling vehicle 9 passes through the gap portion 11, the vibration caused by the gap portion 11 can be reduced.

[0060] At the same time with reference Figure 5 , which is a schematic diagram of the structure of the chamfered portion of the overhead travelling vehicle track provided in the third preferred embodiment of the present application, it can be clearly seen from the figure that this embodiment is similar to the above-mentioned embodiment, and the only difference is that the overhead travelling vehicle track 1 has a plurality of chamfered portions 12 at the side adjacent to the gap portion 11, and the chamfered portions 12 are inclined surfaces or arc surfaces. The design of the chamfered portions 12 allows a certain degree of deviation of the vertical wall mechanism 3 before entering the gap portion 11, and because the width of the opening end of the chamfered portion 12 is greater than the width of the gap portion 11, even if the width of the gap portion 11 is reduced, the vertical wall mechanism 3 can be accurately guided to enter the gap portion 11, and the vibration caused by the gap portion 11 can be reduced when the overhead travelling vehicle 9 passes through the gap portion 11.

[0061] At the same time with reference Figure 6 1 is a schematic diagram of the smoke shielding structure of the overhead crane track provided in the fourth preferred embodiment of the present application. It can be clearly seen from the figure that the present embodiment is similar to the above-mentioned embodiment, and the only difference is that at least one proximity sensing component 82 connected to the control device 8 is provided on the side of the overhead crane track 1 adjacent to the vertical wall mechanism 3. When the vertical wall mechanism 3 is in the closed position and the proximity sensing component 82 detects the overhead crane 9, a warning signal is sent to the control device 8 to stop the overhead crane 9 from moving. The proximity sensing component 82 is a proximity sensor, which is a sensor that can detect the presence of objects nearby without contact. It can be one of a capacitive sensor, a photoelectric sensor or an inductive sensor. In this embodiment, an infrared photoelectric sensor is used as an example. Generally speaking, when the wall hanging mechanism 3 is in the descending position, the control device 8 will also send a stop signal to the overhead travelling crane 9 at the same time. However, when a fire occurs, there may be uncontrollable factors that cause the overhead travelling crane 9 to fail to receive the signal. Therefore, the proximity sensor component 82 can be additionally used to detect whether the overhead travelling crane 9 is approaching the wall hanging mechanism 3, thereby adding a safety mechanism for the overhead travelling crane 9 to prevent collision.

[0062] At the same time with reference Figure 7FIG. 1 is a schematic diagram of the structure of the movable fixing member provided in the fifth preferred embodiment of the present application. It can be clearly seen from the figure that the present embodiment is similar to the above-mentioned embodiment, and the only difference is that the movable fixing member 4 has a magnetic body 41 and a plurality of pulleys 42 arranged on one side of the magnetic body 41. By utilizing the design of the magnetic body 41 and the pulley 42, the movable fixing member 4 is formed into a pulley form, which can move smoothly in the vertical wall guide rail 2, ensure the normal movement of the vertical wall mechanism 3, and reduce the wear of the vertical wall guide rail 2, the movable fixing member 4, and the traction assembly 7, thereby increasing the service life.

[0063] At the same time with reference Figure 8 As shown, it is a structural schematic diagram of the vertical wall mechanism 3 provided in the sixth preferred embodiment of the present application. It can be clearly seen from the figure that this embodiment is similar to the above-mentioned embodiment, and the only difference is that the vertical wall mechanism 3 has a plurality of shielding sheets 32 and a plurality of connecting parts 321 arranged between each shielding sheet 32, so that these shielding sheets 32 are connected and folded using the connecting parts 321. The connecting portion 321 is a soft material such as plastic or a pivoting structure such as a hinge. The present embodiment takes a soft material as an example, so the design of the shielding sheet 32 ​​is utilized so that the vertical wall mechanism 3 can be folded in a smaller volume and placed on one side of the overhead traveling vehicle track 1 when not in use. This not only can be applied to a smaller space, but also can reduce the windward surface area of ​​the vertical wall mechanism 3, thereby preventing the vertical wall mechanism 3 from shaking unnecessarily in the open position, thereby increasing the service life of the movable fixing member 4 and the vertical wall guide rail 2. When in use, the movable fixing member 4 is utilized to drive the first shielding sheet 32a, and the connecting portion 321 on one side of the first shielding sheet 32a is utilized to drive the second shielding sheet 32b, and so on to unfold all the shielding sheets 32.

[0064] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
