The embodiments described below by reference to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0035] As Figures 1-7 Indicated, the utility model provides a track equipment for carrying and guiding the movement of the hanging rail type robot 9, wherein the track equipment can be arranged on the wall 8.

[0036] The track equipment comprises a fixed track 1, a lifting track 2, a lifting driving mechanism 3 and a positioning mechanism 4. The fixed track 1 is provided with a notch section 11, the lifting track 2 is arranged opposite to the notch section 11 along the vertical direction (i.e. the Z direction in the drawing), and the driving end of the lifting driving mechanism 3 is connected to the lifting track 2 for driving the lifting track 2 to move along the vertical direction, so that the lifting track 2 can be connected with the fixed track 1 at the notch section 11 or lowered to a lower position.

[0037] Meanwhile, the positioning mechanism 4 comprises two telescopic rods 41 movably arranged at both ends of the lifting track 2 respectively, when the lifting track 2 is located at the notch section 11, the two telescopic rods 41 can extend out of the lifting track 2 along the first direction (i.e. the X direction in the drawing) to be clamped on the fixed track 1, ensuring that the lifting track 2 is fixedly connected with the fixed track 1, when the lifting track 2 is separated from the notch section 11, the two telescopic rods 41 can retract into the lifting track 2 along the first direction, at this time, the lifting track 2 is disconnected with the fixed track 1, to facilitate the lifting driving mechanism 3 to drive the lifting track 2 to lift, wherein the hanging rail type robot 9 can move on the fixed track 1 and the lifting track 2, so that the hanging rail type robot 9 can follow the lifting track 2 to lift, to facilitate the maintenance of the hanging rail type robot 9. Optionally, the fixed track 1 and the lifting track 2 are both rectangular pipe structures, so the weight is lighter, reducing the construction difficulty of the track arrangement, and the cost of the rectangular pipe structure is lower.

[0038] The track device can drive the lifting track 2 to lift the hanging rail robot 9 through the lifting driving mechanism 3, so as to realize the maintenance of the hanging rail robot 9, without the need for workers to climb to a high place to take down the hanging rail robot 9 by means of a ladder or a scaffold, thereby improving the safety during the process of loading and unloading the hanging rail robot 9, and the gap section 11 can be located at any position of the fixed track 1 according to the requirement, so that the hanging rail robot 9 can be disassembled at any position, and therefore, a large amount of time is not wasted to move the hanging rail robot 9 to the end of the fixed track 1, thereby improving the maintenance efficiency of the hanging rail robot 9. Optionally, a plurality of gap sections 11 are arranged on the fixed track 1, and the lifting track 2, the lifting driving mechanism 3 and the positioning mechanism 4 are arranged at the position corresponding to each gap section 11, so that when facing a long fixed track 1, the workers can move the hanging rail robot 9 to the lifting track 2 close to them to realize disassembly and maintenance.

[0039] As shown in Figures 4-7 The positioning mechanism 4 further comprises a transmission gear 45 arranged on the lifting track 2, and the transmission rack 413 is arranged at one end of the telescopic rod 41 away from the fixed track 1, and the transmission racks 413 of the two telescopic rods 41 are respectively meshed and connected to the opposite sides of the transmission gear 45, so that when one of the telescopic rods 41 extends out of the lifting track 2, the other telescopic rod 41 can also extend or retract the lifting track 2 through transmission, and when one of the telescopic rods 41 retracts into the lifting track 2, the other telescopic rod 41 can also retract into the lifting track 2 through transmission.

[0040] Specifically, the positioning mechanism 4 comprises an elastic member 42, the telescopic rod 41 has a mounting through slot 411, the elastic member 42 is arranged in the mounting through slot 411, the lifting track 2 is provided with a baffle 21 located in the mounting through slot 411, one end of the elastic member 42 abuts against the slot wall of the mounting through slot 411, and the other end of the elastic member 42 abuts against the baffle 21, and the elastic member 42 always has a movement trend of driving the telescopic rod 41 to extend out of the lifting track 2 in the first direction, so that when no external force is applied to the telescopic rod 41, the telescopic rod 41 extends out of the lifting track 2 and is inserted into the fixed track 1, to ensure the stable connection of the lifting track 2 and the fixed track 1, so that the hanging rail robot 9 can be continuously moved from the lifting track 2 and the fixed track 1.

[0041] Meanwhile, the positioning mechanism 4 further comprises an elastic positioning pin 43, the elastic positioning pin 43 is arranged on the telescopic rod 41, the positioning hole 22 is arranged on the lifting rail 2, the pressing rod 12 is arranged on the fixed rail 1, and the positioning hole 22 and the pressing rod 12 are arranged opposite in the vertical direction. When the lifting rail 2 is separated from the gap section 11, the elastic positioning pin 43 can be stretched and inserted into the positioning hole 22, so that the elastic positioning pin 43 can position the telescopic rod 41, so that the telescopic rod 41 is fixed in the lifting rail 2 in the retracted state, thereby avoiding the telescopic rod 41 from being stretched out of the lifting rail 2 under the influence of the elastic member 42 when the lifting rail 2 is separated from the gap section 11. When the lifting rail 2 is located in the gap section 11, the pressing rod 12 can press the elastic positioning pin 43 into the lifting rail 2, so that the elastic positioning pin 43 is separated from the positioning hole 22, so that the telescopic rod 41 can be stretched out of the lifting rail 2 under the influence of the elastic member 42, thereby realizing the insertion of the fixed rail 1.

[0042] Further, the positioning mechanism 4 further comprises a stop block 44, the stop block 44 is movably arranged on the lifting rail 2 in the second direction (i.e. the Y direction in the drawing), and the side end of the telescopic rod 41 is provided with a dovetail groove 412 arranged obliquely in the first direction. The stop block 44 is movably arranged in the dovetail groove 412, so that during the process of the telescopic rod 41 stretching out of the lifting rail 2 and retracting into the lifting rail 2, the stop block 44 can move relative to the telescopic rod 41 through the dovetail groove 412, that is, the stop block 44 moves relative to the telescopic rod 41 in the first direction and the second direction. Specifically, when the telescopic rod 41 stretches out of the lifting rail 2, the telescopic rod 41 can drive the stop block 44 to retract into the lifting rail 2 in the second direction, at this time the rail-mounted robot 9 can normally move on the lifting rail 2. When the telescopic rod 41 retracts into the lifting rail 2, the telescopic rod 41 can drive the stop block 44 to stretch out of the lifting rail 2 in the second direction to stop the rail-mounted robot 9, at this time the rail-mounted robot 9 is limited on the lifting rail 2, thereby avoiding the rail-mounted robot 9 from moving and falling out of the lifting rail 2 during the lifting process of the lifting rail 2. Wherein, the first direction, the second direction and the vertical direction are arranged perpendicular to each other.

When the lifting track 2 is located in the notch section 11, the unlocking rod 51 is arranged opposite to the telescopic rod 41 in the first direction, so that a worker can hold the unlocking rotating rod 53 to rotate the unlocking gear 52, and the unlocking gear 52 drives the unlocking rod 51 to move. When the lifting track 2 is located in the notch section 11, the unlocking rod 51 can abut against the telescopic rod 41 during the process of extending out of the fixed track 1, so that the telescopic rod 41 is retracted into the lifting track 2 against the elastic force of the elastic member 42, thereby achieving the disconnection between the lifting track 2 and the fixed track 1.

[0044] Further, the lifting driving mechanism 3 comprises a self-locking winch 31, a driving rope 32, a fixed pulley 33 and a movable pulley 34. The fixed track 1 is provided with a rope support 13, and the lifting track 2 is provided with a pulley support 23. The movable pulley 34 is rotatably arranged on the pulley support 23. One end of the driving rope 32 is connected to the self-locking winch 31, and the other end of the driving rope 32 is connected to the rope support 13 after being arranged on the fixed pulley 33 and the movable pulley 34 in sequence. Thus, the self-locking winch 31 can wind and unwind the driving rope 32, so that the driving rope 32 pulls the movable pulley 34 to move up and down after being redirected by the fixed pulley 33, and then pulls the lifting track 2 to move up and down. Optionally, the pulley support 23 is provided with a limiting plate 231, and the rope support 13 is provided with a limiting hole 131. When the lifting track 2 is located in the notch section 11, the limiting plate 231 is inserted into the limiting hole 131, so that the insertion positioning of the limiting plate 231 and the limiting hole 131 can ensure that the two ends of the lifting track 2 are aligned with the fixed track 1. Further optionally, the driving rope 32 is connected to the rope support 13 after being arranged on the movable pulley 34, so that the driving rope 32 is guided on both sides of the rope support 13 to avoid tangling during winding and unwinding.

Optionally, the hoisting assembly 6 comprises a basket screw, a fixing clamp and a hoisting rope, one end of the hoisting rope is connected to the wall 8, and the other end is locked to the fixed track 1 through the basket screw and the fixing clamp, so as to facilitate the adjustment of the height of the fixed track 1 and improve the flexibility of the adjustment. Further optionally, the telescopic reinforcing assembly 7 comprises two porous plates, the two porous plates are detachably connected through a bolt assembly, and the length of the two porous plates as a whole can be adjusted by adjusting the mounting position of the bolt assembly on the two porous plates, so as to be suitable for actual fixing requirements.
