Description
Technical Field
[0001] This utility model relates to the field of monorail technology, specifically to a monorail track avoidance structure. Background Technology
[0002] One of the most important functions of monorail transport is the overall transport of hydraulic supports, including the rails, locomotive, and lifting beam. The rails are installed and fixed to the tunnel roof using chain locks to form the track. The locomotive runs on the rails and uses the lifting beam to transport the hydraulic supports.
[0003] The monorail is suspended from the top of the tunnel. When the monorail is deployed underground, it may encounter interference with other moving parts, such as the overhead personnel carrier. In this case, the upper part of the monorail needs to be moved aside to allow the other equipment to operate normally. Utility Model Content

[0005] This utility model is achieved through the following technical solution: a single-rail suspension track avoidance structure is provided, including a track a and a track b, both of which are fixedly arranged, and a movable track that connects between track a and track b. The connecting end of the movable track is hinged to the end of track b through a hinge structure, and the movable end of the movable track connects to the end of track a. The structure also includes a drive mechanism for driving the movable track to swing, and the movable track is locked by a locking mechanism when it connects with track a.

A locking plate is fixed on the track a, and the locking plate has a socket adapted to the locking shaft.
[0010] As an optimization, a fixed avoidance support frame is also included, on which a locking avoidance plate is fixedly connected. The locking avoidance plate has an avoidance insertion hole, and when the movable track avoids avoidance, the locking shaft is inserted into the avoidance insertion hole to achieve locking.
[0011] As an optimization, a limit baffle is fixedly connected to track a, and an avoidance baffle is fixedly connected to the avoidance support frame.
[0012] As an optimization, the locking mechanism further includes a return proximity switch and an extension proximity switch. The extension proximity switch is triggered when the locking shaft extends, and the return proximity switch is triggered when the locking shaft retracts.
[0013] As an optimization, the hinge structure includes an upper support fixed to the upper end face of the movable track connection end and a fixed seat fixed to the upper end face of track b.

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0028] like Figures 1-9 As shown, this utility model discloses a monorail overhead crane track clearance structure, which includes two fixedly installed tracks a1 and b2, which are on a straight line or nearly straight. A certain gap is left between tracks a1 and b2 to form a notch. The structure also includes a movable track 3 that connects to tracks a1 and b2. When the two ends of the movable track 3 are connected to tracks a1 and b2 respectively, it is used to fill the gap.
[0029] It also includes a fixed frame 4, which is a horizontal frame made of rectangular tubes and fixed to the top of the tunnel. The tracks a1 and b2 are both fixed to the two ends below the fixed frame 4. A support beam 21 is fixed to the fixed frame 4, and a support wheel bracket 19 is fixed to the movable track 3. The support wheel bracket 19 is equipped with support wheels 20 that travel on the support beam 21, thereby supporting the movable track 3 through the support wheels 20.
[0030] like Figure 1As shown, connecting plates 13 are fixedly connected to the upper ends of both track a1 and track b2. The connecting plates 13 are vertically welded into the middle groove on the upper surface of the track. A U-shaped groove is provided at the upper end of the connecting plate 13, and a connecting rectangular tube 12 is fixedly connected within the U-shaped groove. The connecting rectangular tube 12 is horizontally positioned, with its upper end welded to the lower end face of the fixing frame 4. The lower end of the connecting rectangular tube 12 is welded into the U-shaped groove of the connecting plate 13, thereby improving the welding strength and the support strength for the track. End plates 14 are welded to both ends of the connecting rectangular tube 12 to reinforce it.
[0031] The above arrangement ensures that there is a certain vertical gap between the track formed by the movable track 3, track a1 and track b2 and the fixed frame 4, which is used to arrange parts and other equipment.
[0032] The connecting end of the movable track 3 is hinged to the end of track b2 via a hinge structure 6, and the hinge axis is vertically arranged. The movable end of the movable track 3 is connected to the end of track a1. Figure 4 As shown, the connecting end of the movable track 3 and the end of the track b2 are both obliquely cut, so as to realize the swing of the movable track 3 while ensuring the continuity when the movable track 3 and the track b2 are connected, and reduce the amount of track swing cut-off.
[0033] like Figure 8 , 9 As shown, the hinge structure 6 includes an upper support 61 fixed to the upper end face of the connecting end of the movable track 3 and a fixed seat 62 fixed to the upper end face of the track b2. The upper support 61 extends to the upper end of the fixed seat 62. The movable track pin 63 passes through the upper support 61 and is threadedly connected to the fixed seat 62, so that the upper support 61 can rotate relative to the movable track pin 63 to achieve hinge.
[0034] The hinge structure 6 also includes a lower support 64 fixed to the lower end face of the track b2 and a lower pin 65 fixed to the lower end face of the connecting end of the movable track 3. The lower end face of the track b2 is cut into a plane, and the lower support 64 is welded to the plane. The lower end face of the connecting end of the movable track 3 is also cut into a plane, and the upper end of the lower pin 65 is welded to the plane.
[0035] The lower support 64 has a connecting slot on the side facing the movable track 3. The bottom of the connecting slot is arc-shaped and its radius is equal to the radius of the lower pin 65. The lower pin 65 is located inside the connecting slot. Therefore, during installation, the movable track 3 can be moved laterally so that the lower pin 65 is inserted into the connecting slot, the upper support 61 is inserted above the fixed seat 62, and then the movable track pin 63 is installed, thereby achieving the connection of the upper and lower positions of the connecting end of the movable track 3. As the movable track 3 is subjected to downward force, the lower pin 65 is pressed tightly against the bottom arc of the connecting slot.
[0036] It also includes a drive mechanism for driving the movable track 3 to swing, the drive mechanism including a drive cylinder 7, one end of the drive cylinder 7 is hinged to the cylinder mounting bracket 8 on the fixed frame 4, and the other end is hinged to the movable track 3.
[0037] Since the movable track 3 needs to be hoisted through after docking with track a1, the movable track 3 is under significant stress. To prevent the movable end of the movable track 3 from sagging, an upper support plate 10 extending above track a1 is fixedly connected to the upper surface of the movable track 3. A lower support plate 9 extending below the movable track 3 is fixedly connected to the lower surface of track a1. When the movable end of the movable track 3 sags, the upper support plate 10 presses against track a1, and the movable end of the movable track 3 presses against the lower support plate 9.
[0038] After the movable track 3 is connected to the track a1, in order to achieve accurate connection, prevent misalignment, and improve the load-bearing capacity of the movable track 3, the movable track 3 is locked by the locking mechanism 5 when connected to the track a1.
[0039] like Figure 7 As shown, the locking mechanism 5 includes a locking shaft guide plate 54 fixed to the movable track 3, a locking shaft 53 slidably connected to the locking shaft guide plate 54, and a locking cylinder 51 that drives the locking shaft 53 to slide. In this embodiment, the locking shaft guide plate 54 and the cylinder mounting plate 52 are welded to the upper support plate 10, the locking cylinder 51 is mounted on the cylinder mounting plate 52, and the telescopic shaft of the locking cylinder 51 passes through the cylinder mounting plate 52 and is coaxially connected to the locking shaft 53.
[0040] A locking plate 56 is fixedly connected to the track a1, and the locking plate 56 has an insertion hole adapted to the locking shaft 53. The front end of the locking shaft 53 is tapered to facilitate insertion into the insertion hole.
[0041] It also includes a fixed clearance support frame 22, which is fixed below the fixed frame 4. A locking clearance plate 23 is fixedly connected to the clearance support frame 22. The locking clearance plate 23 has a clearance insertion hole. When the movable track 3 makes clearance, the locking shaft 53 is inserted into the clearance insertion hole to lock it.
[0042] like Figure 3 , 4 As shown, a limiting baffle 11 is fixedly connected to track a1, and an avoidance baffle 24 is fixedly connected to the avoidance support frame 22. When the drive cylinder 7 drives the movable track 3 to swing to dock with track a1, the side of the movable track 3 hits the limiting baffle 11 and stops, achieving precise docking between the movable track 3 and track a1. When the drive cylinder 7 drives the movable track 3 to swing to avoid track a1, the side of the movable track 3 hits the avoidance baffle 24 and stops, facilitating the insertion of the locking shaft 53 into the avoidance socket.
[0043] The fixed frame 4 is also equipped with a clearance proximity switch 25. When the movable track 3 clears the clearance position, the clearance proximity switch 25 is triggered, and the system recognizes that the movable track 3 has cleared the clearance position.
[0044] The locking mechanism 5 also includes a return proximity switch 55 and an extension proximity switch 57. A protrusion is fixed to the outside of the locking shaft 53. When the locking shaft 53 is retracted, the protrusion triggers the return proximity switch 55, and the system recognizes that the locking shaft 53 has returned to its original position.
[0045] There are two extension proximity switches 57. One extension proximity switch 57 is installed on the locking plate 56 and the locking clearance plate 23. When the locking shaft 53 extends, the protrusion triggers the corresponding extension proximity switch 57.
[0046] The track a1 is equipped with a car stopper 17 and a car stopper cylinder 18 that drives the car stopper 17 to swing. The car stopper 17 is hinged to the upper end of the track a1. Its lower end swings downward to stop the car. The extension and retraction of the car stopper cylinder 18 drives the lower end of the car stopper 17 to swing upward, thereby allowing the monorail crane to pass and preventing the monorail crane from passing when the moving track 3 needs to avoid it.
[0047] How to use this utility model:
[0048] When the monorail is working normally, the movable track 3 is used to connect with track a1 and track b2 to form a continuous track for the monorail to move. At this time, the locking shaft 53 in the locking mechanism 5 is inserted into the insertion hole of the locking plate 56 to achieve a precise and stable connection.
[0049] When avoidance is required, the locking cylinder 51 retracts, causing the locking shaft 53 to be pulled out of the insertion hole of the locking plate 56. After the proximity switch 55 detects that the locking shaft 53 is in place, it drives the cylinder 7 to retract, causing the movable track 3 to swing laterally on the horizontal plane, thereby forming a gap between track a1 and track b2. After the movable track 3 avoids the obstacle, the locking cylinder 51 extends, causing the locking shaft 53 to be inserted into the avoidance insertion hole.
[0050] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
