The runway for carrying the moving vehicle is made of profiles; for the known profiles for runways, most of them are assembled into runways for moving vehicles by using commercially available profiles through different components. These profiles are mostly in standardized series, with low prices, convenient procurement, and high mechanical strength; however, they are difficult to assemble, have a large amount of secondary processing, high on-site installation difficulty, poor accuracy of the assembled runway, and great difficulty in the design and manufacture of moving vehicles; as a result, for some professional application designs, commercially available profiles are difficult to apply and cannot meet the needs of the development of science and technology. Summary of the Invention

[0003] In view of the above problems, a brand-new multi-functional runway assembled from profiles and related components is designed.

[0004] The object of the present invention is achieved as follows:

[0007] A cavity that can reduce the weight of the profile and runs through the entire length of the profile is allowed to be opened in the vertical plate of the profile;

[0008] Below the horizontal plate of the profile and on both sides of the vertical plate, mirror - symmetric grooves opening downward and running through the entire length of the profile are designed; on both sides of the middle and lower parts of the vertical plate, mirror - symmetric horizontally - opening grooves running through the entire length of the profile are designed; on both sides of the near - lower part of the vertical plate of the profile, mirror - symmetric trapezoidal ribs running through the entire length of the profile and symmetric about the central plane of the vertical plate are designed, and an auxiliary hole running through the entire length of the profile is designed at the symmetric center position of the two ribs;

[0009] The outer contour of the bottom cross - section of the vertical plate is rectangular, and a groove running through the entire length of the profile is designed at the symmetric center of the bottom end. The upward outer contour of the bottom rectangle is connected to the outer contour of the bottom surface of the rib running through the entire length of the profile;

[0010] The horizontal section of the profile has an upper contour that is a horizontally mirror-symmetrical plane that runs through the entire length of the profile and is placed on both sides of the vertical section; on both vertical surfaces of the horizontal section, there are mirror-symmetrical grooves that run through the entire length of the profile; within the horizontal section adjacent to the grooves on both sides of the profile's horizontal section, there are mirror-symmetrical auxiliary holes that run through the entire length of the profile.

[0011] The profile is made of a metal material with good plasticity and is cut to the same length. The mounting parts are used for hoisting or wall-mounted connection of the profile. Two mounting parts are used at the interface of every two profiles; the mounting parts are placed on both sides of the top of the profile. There are several corresponding holes between the lower part of the mounting part and the groove at the top of the profile. Drive rivets or screws are passed through the holes in the lower part of the mounting part and inserted into the grooves at the top of the two profiles, and the two are fastened to complete the connection at the top between the two profiles.

[0012] The grooves on both sides of the vertical section below the horizontal section of the profile are inclined or right-angled grooves, and the grooves on both sides of the middle and lower parts of the vertical section of the profile are inwardly tapered grooves. The grooves can be used to install sliding contact lines for transmitting current and signals; the grooves can also be assembled with a plug-in board for clamping new components. The upper end of the sliding contact line is stuck in the inclined or right-angled groove at the upper part of the vertical section, and the lower end is fastened outside the horizontally open inwardly tapered groove with a pressing plate through which drive rivets or screws are passed.

[0013] The outer contour of the trapezoidal ribs on both sides near the lower part of the vertical section of the profile can be used as a guiding runway; the moving vehicle is equipped with a set of guiding wheels, and the guiding wheels are clamped outside the two ribs.

[0014] When using cables for power supply and signal transmission, the upper contour surfaces of the two ribs become runways for carrying the cable towing mechanism; the cable towing mechanism is composed of multiple cable towing groups. Each cable towing group consists of two pulleys with an axle passing through them. The axles are respectively inserted into the holes at the upper ends of the vertical plates of the cable towing bracket and fixed with nuts. There are two holes on the horizontal plate below the cable towing bracket for installing "U" - shaped clamps, thus forming a cable towing group; the gap size between the "U" - shaped clamp and the cable towing bracket is adjustable. The cable is threaded through it, an appropriate length of the cable is taken and placed, the spacing of each cable towing group is arranged, and the nuts on the "U" - shaped clamp are adjusted to position the cable, thus forming the cable towing mechanism; the two pulleys of each cable towing group in the cable towing mechanism are respectively hung on the runways formed by the upper contour surfaces of the ribs, and the cable can be smoothly and quietly retracted and extended with the moving vehicle.

[0015] The inner contour of the groove at the bottom end of the vertical plate of the profile is composed of an elliptical cylindrical hole connected by two straight surfaces; it can also be composed of a rectangular groove with chamfered top connected by two straight surfaces; holes are processed on the rack, and the rack is horizontally fixed under the groove at the bottom end of the vertical plate by blind rivets or screws for receiving the drive of the straight-running gear of the moving vehicle in the horizontal state; the rack connector is in the shape of a right angle, and there are holes on its horizontal plate surface and vertical plate surface. The horizontal plate surface of the rack connector is fastened under the groove at the bottom surface of the vertical plate by blind rivets or screws. At this time, the vertical plate surface of the rack connector should face downward, and the rack with downward teeth is fixed on the vertical plate surface of the rack connector by blind rivets. At this time, the rack is in a vertical state and can receive the drive of the ring gear of the moving vehicle performing two-dimensional movement.

[0017] Half-length connecting strips are inserted into the grooves on the vertical surfaces on both sides of the horizontal plate and the grooves at the bottom of the vertical plate at the butt ends of the two profiles respectively, and the connecting strips are squeezed and pressed tightly with screws respectively, thus forming a stable inverted isosceles triangle structure connected by three connecting strips, connecting the two profiles together without spacing, misalignment and tightly; repeat the above operation until a complete runway is assembled as required.

[0018] The cross-sectional contour of the auxiliary holes in the horizontal plates on both sides of the profile is in the shape of two unequal-diameter arcs connected by two straight lines; the auxiliary holes at the symmetric center positions of the two ribs of the vertical plate are composed of two arcs and an inner cavity similar to the shape of the two ribs.

[0019] The aforementioned multi-section profiles and related components can be quickly assembled into corresponding multi-functional runways for various power sources, signal transmission methods and moving vehicles with different structures; in order to adapt to environmental characteristics and motion trajectory requirements, they can be assembled into straight runways, curved runways, etc., providing a favorable basic condition for the design of moving vehicles.

[0022] 2. The profiles of the present invention are combined into a runway, and no secondary processing is required for on-site assembly, with high installation efficiency and low working intensity.

[0023] The profiles of the present invention can be assembled into straight runways, curved runways, or runways with multi-dimensional complex shapes, and are adapted to electrodes or cables for transmitting commercial power and other power sources.

The blind rivets 3 or screws 4 are passed through the holes in the lower part of the mounting parts 2 and inserted into the grooves at the top of the two profiles 1, and the two are fastened together with tools to complete the connection at the top between the two profiles, waiting for hoisting or wall mounting; repeat the above operations until a complete multi-functional runway is assembled as required; the design of the internal tapered groove running through the entire length provides a condition for hoisting and wall mounting of the profiles without secondary processing, and fasteners such as screws 4 and blind rivets 3 can be selected for installation. In particular, the application of blind rivets 3 has increased the installation efficiency several times.

Two holes are opened on the horizontal plate below the towing cable bracket 10 for fitting a "U"-shaped card 12, thereby forming a towing cable group; there is a large gap between the "U"-shaped card 12 and the towing cable bracket 10 The cable 13 is installed in between, and the cable 13 of appropriate length is put in and taken out, and the spacing of each towing cable group is arranged. The nut 11 on the "U"-shaped card 12 is adjusted to position the cable 13, thereby forming a towing cable traction mechanism; the two pulleys 8 of each towing cable group in the towing cable traction mechanism are hung on the runway formed by the contour surface of the convex rib, and the cable can be smoothly and quietly retracted and released with the moving vehicle. This structure solves the problem that exposed electrodes cannot be used for power supply in some occasions, and at the same time, there is no need to set up a suspension cable for installing the towing cable.

[0043] Figure 5 , Figure 6 In the embodiment, the outer contour of the bottom cross section of the vertical plate of the profile 1 is rectangular, and a groove running through the entire length of the profile 1 is designed at the symmetrical center of the bottom end. The inner contour of the groove is composed of two straight surfaces connecting an elliptical cylindrical hole; it can also be composed of two straight surfaces connecting a rectangular groove with a chamfered top; the outer contour of the bottom rectangle is connected to the outer contour of the bottom surface of the convex rib running through the entire length of the profile 1; a hole is processed on the rack 14, and the rack 14 is horizontally fixed under the groove at the bottom end of the vertical plate by a blind rivet 3 or a screw 4, which is used to receive the drive of the straight gear 15 of the mobile car in a horizontal state; the rack connecting member 16 is in a right-angle shape, and its horizontal plate surface and vertical plate surface are both provided with holes, through The horizontal plate surface of the rack connector 16 is fastened to the groove on the bottom surface of the vertical plate by means of blind rivets 3 or screws 4. At this time, the vertical plate surface of the rack connector 16 should be downward, and the rack 14 with downward teeth is fixed to the vertical plate surface of the rack connector 16 by means of blind rivets 3. At this time, the rack 14 is in a vertical state and can be driven by the circular gear 17 of the mobile vehicle that performs two-dimensional motion; the groove at the bottom end of the vertical plate and running through the entire length of the profile 1 is used for the installation of the rack 14 and the rack connector 16, providing a condition that does not require secondary processing and can select a variety of fasteners for installation, which is particularly suitable for the application of blind rivets that improve the efficiency several times.

[0044] Figure 4 ,Figure 3 In it, for the horizontal plate part of the profile 1, the upper contour thereof is a horizontally mirror-symmetrical plane that runs through the entire length of the profile 1 and is disposed on both sides of the vertical plate, and the two horizontal planes form a runway for the moving vehicle load-bearing wheels 18 to travel; the inner contour of the vertical plane grooves on both sides of the horizontal plate is composed of two straight-plane-connected elliptical cylindrical holes; it can also be composed of two straight-plane-connected rectangular grooves with chamfered tops; if the moving vehicle is applied outdoors or in an environment with water dripping, a waterproof and rainproof plate 19 can be installed outside the groove of the horizontal plate with blind rivets 3 or screws 4; the waterproof and rainproof plate 19 is organically combined with the structural design of the profile 1, effectively solving the problem that the runway with exposed electrodes is not suitable for outdoor use; the groove design of the vertical planes on both sides of the horizontal plate creates conditions for selecting a variety of fasteners and efficient installation.

The cross-sectional contour of the auxiliary holes is in the shape of two unequal-diameter arcs connected by two straight lines. The auxiliary holes at the symmetrical center positions of the two convex ribs on the vertical plate are composed of two arcs and an inner cavity similar to the outer shape of the two convex ribs; the above three auxiliary holes are used for clamping fixtures during secondary processing to achieve the purpose of non-destructive processing of the profile 1 and reducing the weight of the profile 1; since the structural design of the profile 1 cannot meet some personalized requirements, some special processing such as milling and drilling needs to be carried out on the profile 1 at this time. These three auxiliary holes provide convenience for the clamping of the work fixtures, ensure that the surface of the profile 1 is not damaged, and ensure the consistency of the processing position and accuracy.
