[0042] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] like Figures 1 to 3 As shown, the present invention provides an automatic installation device for roof anti-cold nails, which welds the anti-cold nails 1 to the roof 2 by welding. The automatic installation device includes a support frame 3, at least one hanger 4, a grinding device 5, a welding device 6 and a control system (not shown in the figure). It is particularly suitable for the installation of roof anti-cold nails of aluminum alloy high-speed EMUs.

[0046] Among them, the support frame 3 is supported on both sides of the width direction of the roof 2 and spans over the roof 2. The support frame 1 can also be moved along the length direction of the vehicle through a moving mechanism (not shown in the figure) to facilitate the change of different working positions in the length direction of the vehicle. A hanger 4 is installed on the support frame 3. The hanger 4 is connected to the support frame 3 through a running mechanism 7 and moves along the support frame 3 in the width direction of the vehicle to change different working positions in the width direction of the vehicle; the grinding device 5 and the welding device 6 are integrated and installed on a hanger 4, that is, a set of grinding devices 5 and welding devices 6 are integrated and installed on each hanger 4. The grinding device 5 is used to grind the oxide film in the installation area, and the welding device 6 is used to install the anti-cold nail 1 on the roof 2 by welding; the above-mentioned running mechanism 7, grinding device 5 and welding device 6 are all connected to the control system and are uniformly controlled by the control system.

[0047] This embodiment also provides another implementation mode, where multiple hangers 4 can be installed simultaneously on one support frame 3, and a set of grinding devices 5 and welding devices 6 are integrated and installed on each hanger 4. In this way, multiple sets of grinding devices 5 and welding devices 6 can be used to work simultaneously, and each set of grinding devices 5 and welding devices 6 has a different working area, which is conducive to improving the working efficiency.

[0048] In this embodiment, before each operation, the set installation position coordinates of all the anti-cold nails in this operation are pre-input into the control system, and the control system controls the movement of the grinding device 5 and the welding device 6 according to the initial coordinates and the set installation position coordinates to realize the fully automatic installation of the anti-cold nails 1 of the entire roof 2.

[0049] The installation device is centrally controlled by a control system, and can realize fully automatic installation of all the anti-cold nails 1 on the entire roof 2, which can not only greatly improve the installation efficiency and installation quality, but also ensure the safety of the installation operation.

[0050] In this embodiment, preferably, the support frame 3 is composed of support blocks 31 at both ends and a slide rail 32 in the middle, the two support blocks 31 are respectively clamped and fixed on the roof profile 8 at both ends of the roof 2, the support blocks 31 have a slide groove 33 matching the shape of the roof profile 8, and the support blocks 31 slide along the roof profile 8. In this way, the entire support frame 3 can move along the length direction of the vehicle, adjust different working positions, and also facilitate accurate control of the coordinate position of the movement of the support frame 3.

[0051] In this embodiment, it is further preferred that at least two groups of rolling elements are installed on the inner wall of the slide 33, and the rolling elements are preferably rollers 34, and the two groups of rollers 34 are respectively supported by rolling on the upper and lower surfaces of the roof profile 8. It is further preferred that three groups of rollers 34 are installed on the inner wall of the slide 33, and the three groups of rollers 34 are respectively connected to the upper, lower and top surfaces of the roof profile 8. The three groups of rollers 34 are connected to a rolling drive device (not shown in the figure), and the rolling drive device can use a motor, and the control system controls the action of the motor to drive the support frame 3 to move in the direction of the vehicle length to achieve fully automatic installation operations. In this way, not only can the support frame 3 slide more smoothly along the vehicle length, but also shaking in the three coordinate directions during sliding can be avoided, so that the movement of the support frame 3 is more stable and the operation quality is guaranteed.

[0052] In this embodiment, preferably, the running mechanism 7 includes a running drive device (not shown) and a running wheel 71, the running wheel 71 is rotatably mounted on the hanger 4, and moves along the vehicle width direction on the slide rail 32 of the support frame 3. The running drive device is connected to the control system, and the control system controls the movement of the running wheel 71 through the running drive device, thereby controlling the grinding device 5 and the welding device 6 to reach the set installation coordinate position.

[0053] In this embodiment, the hanger 4 has an inverted L-shaped structure as a whole, and the side extends in the vertical direction. The grinding device 5 and the welding device 6 are installed on the side of the hanger 4. There is a C-shaped groove 41 at the top of the hanger 4, and the running wheel 71 is embedded in the C-shaped groove 41. The C-shaped groove 41 can play a certain protective role for the running wheel 71.

[0054] In this embodiment, the grinding device 5 preferably includes a grinding wheel 51 and a grinding drive device (not shown in the figure), and the oxide film around the coordinate position is removed by the grinding wheel 51. The grinding drive device is connected to the control system, and the grinding drive device can be a motor or a duct machine.

[0055] The welding device 6 includes a shell 61 and a welding gun 62 installed inside the shell 61 . The welding gun 62 is used to melt the end of the anti-cold nail 1 through electric current, and then the anti-cold nail 1 is welded to the roof 2 .

[0056] In this embodiment, preferably, a first lifting mechanism 9 is installed on the hanger 4, and the grinding device 5 and the welding device 6 are both connected to the first lifting mechanism 9, and the first lifting mechanism 9 is connected to the control system. The first lifting mechanism 9 drives the grinding device 5 and the welding device 6 to rise and fall in the vertical direction, so that the grinding device 5 and the welding device 6 can selectively enter the designated working height respectively.

[0057] The lifting and lowering of the grinding device 5 and the welding device 6 in the device are completed by the first lifting mechanism 9, which can make the structure of the entire installation device simpler, reduce costs, and be easy to control. The device only needs to accurately control the lifting distance of the grinding device 5 and the welding device 6 through the control system. When grinding is required before welding, the grinding device 5 is lowered to the specified working height, and when welding is required, the welding device 6 is lowered to the specified working height. Among them, the specified working height of the grinding device 5 is different from the specified working height of the welding device 6, ensuring that when one device reaches the specified working height, the other device will not enter the working height area.

[0058] The designated working height of the grinding wheel 51 in the grinding device 5 is the height in contact with the surface of the roof 2, and the height relative to the surface of the roof 2 is 0. At this time, the welding device 6 is located above the grinding wheel 51 as a whole. After the grinding is completed, the grinding wheel 51 is lifted up and separated from the surface of the roof 2. When welding is required, the first lifting mechanism 9 is restarted to lower the welding device 6, and the grinding device 5 is also lowered at this time. In order to prevent the grinding wheel 51 from contacting the surface of the roof 2, the lowering distance of the welding device 6 is less than the lowering distance required by the grinding device 5.

[0059] In order to complete the welding, in this embodiment, a second lifting mechanism 10 is further preferably installed on the welding gun 62, and the second lifting mechanism 10 is connected to the control system, and the second lifting mechanism 10 drives the welding gun 62 to move up and down relative to the shell 61 to achieve the installation of the cold-proof nail 1. Since the welding gun 62 moves downward alone and the shell 61 does not move, the grinding wheel 51 will not continue to move downward and contact the roof 2 during this process.

[0060] In this embodiment, it is further preferred that the first lifting mechanism 9 includes a housing 91, a first driving device (not shown in the figure) and a first transmission mechanism, the first driving device is connected to the control system, the input end of the first transmission mechanism is connected to the first driving device, the output end of the first transmission mechanism is connected to the housing 91, and the grinding device 5 and the welding device 6 are respectively connected to the housing 91. Specifically, the housing 61 in the welding device 6 and the grinding wheel 51 in the grinding device 5 are respectively connected to the housing 91. When the first driving device is running, the housing 91 is driven to move up and down through the first transmission mechanism, thereby driving the grinding device 5 and the welding device 6 to move up and down.

[0061] The first transmission mechanism can adopt any structure that can achieve lifting and lowering in the prior art. In this embodiment, in order to simplify the structure of the device and reduce costs, the first transmission mechanism preferably adopts a rack and pinion transmission mechanism. The first drive device can adopt a motor, or a cylinder or a hydraulic cylinder.

[0062] The rack and pinion transmission mechanism includes a rack 92 and a gear 93. The first driving device is installed on the shell 91. The rack 92 is fixed to the side of the hanger 4 in the vertical direction. The gear 93 and the rack 92 are meshed with each other. The output end of the first driving device is fixedly connected to the central axis of the gear 93. At the same time, the central axis of the gear 93 is also fixedly connected to the shell 91. When the first driving device drives the gear 93 to rotate, the gear 93 moves up and down relative to the rack 94, thereby driving the shell 91 to move up and down, and finally driving the grinding device 5 and the welding device 6 to move up and down.

[0063] In order to further reduce the height of the grinding wheel 51 relative to the outer shell 61 in the welding device 6, the grinding wheel 51 is connected to the shell 91 via a connecting piece 11, which extends downward from the shell 91 to reduce the height of the grinding wheel 51 relative to the welding device 6.

[0064] In this embodiment, it is further preferred that the second lifting mechanism 10 includes a second driving device (not shown in the figure) and a second transmission mechanism. The second transmission mechanism can adopt any transmission mechanism in the prior art. In this embodiment, in order to simplify the device structure and reduce costs, the second transmission mechanism preferably adopts a lead screw pair, which is composed of a lead screw 101 and a lead screw slider 102. The welding gun 62 is fixedly connected to the lead screw slider 102, and the lead screw 101 is connected to the second driving device. The second driving device can adopt a motor, and the second driving device is installed on the housing 61. The second driving device drives the lead screw 101 to rotate, thereby causing the lead screw slider 102 to move up and down on the lead screw 101, thereby driving the welding gun 62 to move up and down relative to the housing 61.

[0065] In this embodiment, the first driving device in the first lifting mechanism 9, the second driving device in the second lifting mechanism 10, the traveling driving device in the traveling mechanism, and the rolling driving device can all be powered by servo motors.

[0066] In this embodiment, further, a nail storage container 12 is installed at the bottom of the welding device 6. The nail storage container 12 is specifically installed below the welding gun 21. A portion of the nail storage container 12 extends out of the outer shell 61 of the welding device 6, and a portion extends into the outer shell 61. One side of the nail storage container 12 is connected to the inner space of the outer shell 61, and the outer shell of the nail storage container 12 is fixed to the outer shell 61 of the welding device 6. A nail loading mechanism 13 is installed in the nail storage container 12, which is used to push the cold-proof nails 1 in the nail storage container 12 forward one by one to the welding position, that is, the position directly below the welding gun 62.

[0067] like Figure 4As shown, in this embodiment, it is further preferred that the nailing mechanism 13 includes a nailing channel 131, which is fixed to the outer shell of the nail storage container 12, and the cold-proof nails 1 are arranged in sequence in the nailing channel 131. The nailing channel 131 is composed of two crossbeams, and the nailing channel 131 is formed between the two crossbeams.

[0068] A first baffle 132 and a spring 133 are respectively installed at both ends of the upper nail channel 131. The first baffle 132 and the spring 133 clamp the cold-proof nail 1 in the upper nail channel 131 from both ends. The installation position and the length of the first baffle 132 limit the first cold-proof nail 1 ( Figure 4 The leftmost cold-proof nail 1) is located at the welding position (i.e., the position directly below the welding gun 62).

[0069] The first baffle 132 can be turned down and installed on the welding device 6. Specifically, the first baffle 132 can be turned down and installed on a support column 134. The bottom of the support column 134 is fixed on the housing 61 of the welding device 6. Through the setting of the support column 134, the height of the first baffle 132 can be raised so that it can abut against the approximately middle position of the anti-cold nail 1, so that the anti-cold nail 1 can be stably restricted in the upper nail channel 131. The first baffle 132 is connected to the support column 134 through a first torsion spring 135, so that the first baffle 132 can only be turned down. In the natural state, the first baffle 132 is kept in a horizontal position to abut against the anti-cold nail 1, and the first anti-cold nail 1 at the leftmost end is restricted to be directly below the welding gun 62. Under the action of the spring 133, the anti-cold nail 1 is pushed forward in sequence and abuts against the end of the first baffle 132.

[0070] A second baffle 136 is provided below the upper nail channel 131. The bottom of the cold-proof nail 1 is supported on the second baffle 136. The second baffle 136 can be turned downward and installed on the housing 61 of the welding device 6. The second baffle 136 is connected to the bottom plate of the housing 61 through a second torsion spring 137, which restricts the second baffle 136 to turn downward and keeps the second baffle 136 in a horizontal state in a natural state. When the welding gun 62 moves downward, the first baffle 132 and the second baffle 135 are pushed to turn downward in turn to avoid the movement path of the cold-proof nail 1.

[0071] Furthermore, a third baffle plate 138 is installed on both sides of the upper nail channel 131, and the two third baffle plates 138 are respectively turned down and installed on the upper nail channel 131. The third baffle plate 138 is connected to the upper nail channel 131 through a third torsion spring 139, which restricts the third baffle plate 138 to only turn down, and keeps the third baffle plate 138 in a horizontal state in a natural state. The third baffle plate 138 extends forward (toward the left side in the figure) from the upper nail channel 131, and the third baffle plates 138 on both sides clamp the cold-proof nail 1 between the two third baffle plates 138, so that when the welding gun 62 moves downward, the upper nail channel 131 can avoid its movement path, and when the welding gun 62 moves downward, it can push the third baffle plate 138 to turn downward to avoid the movement path of the welding gun 62.

[0072] When the welding gun 62 moves downward, the anti-cold nail 1 is loaded into the welding gun 62. In the process of the welding gun 62 moving downward, the first baffle 132, the second baffle 136 and the third baffle 138 are pushed to flip downward to avoid the movement path of the welding gun 62. At the same time, the remaining anti-cold nails 1 are moved backward ( Figure 4 The spring 133 is squeezed in the direction of the middle right side. After the welding is completed, the welding gun 62 moves upward. During this process, the first baffle 132, the second baffle 136 and the third baffle 138 are restored to a horizontal state under the action of their respective torsion springs. Under the action of the spring 133, the cold-proof nail 1 is squeezed onto the first baffle 132, ensuring that the leftmost cold-proof nail 1 is directly under the welding gun 62, thereby realizing the automatic nailing of the cold-proof nail 1.

[0073] The present invention also provides a method for installing an automatic installation device for roof anti-cold nails, comprising the following steps:

[0074] S1, placing the support frame 3 on the roof 2, and inputting the installation position coordinates of the anti-cold nail 1 into the control system;

[0075] S2, the control system drives the running mechanism 7 to move left and right along the support frame 3 according to the position coordinates, so that the grinding device 6 is above the coordinate position;

[0076] S3, driving the first lifting mechanism 9 to move the grinding wheel 51 in the grinding device 5 downward by a set distance to a specified working height, and after removing the oxide film around the coordinate position, driving the first lifting mechanism 9 to move the grinding wheel 51 upward to leave the roof 2;

[0077] S4, the control system drives the running mechanism 7 to move left and right along the support frame 3 according to the position coordinates, so that the welding device 6 is above the coordinate position;

[0078] S5, driving the first lifting mechanism 9 to make the housing 61 in the welding device 6 move downward for a certain distance, and the welding gun 62 is then driven by the second lifting mechanism 10 to continue to move downward, pressing the anti-cold nail 1 onto the roof 2, and at the same time, melting the end of the anti-cold nail 1 by electric current, and welding the anti-cold nail 1 to the roof 2;

[0079] S6. After welding is completed, the welding gun 62 is moved upward by the second lifting mechanism 10, and the cold-proof nails 1 in the nail storage container 12 are pushed to the welding position directly below the welding gun 62;

[0080] S7, repeating steps S2-S6 to realize the automatic installation process of all the cold-proof nails 1 in the specified position of one of the vehicle length directions at the specified coordinate position;

[0081] S8, control the support frame to move to the next coordinate position along the vehicle length direction, repeat the above steps S2-S7, and realize the automatic installation process of all cold-proof nails 1 at the specified coordinate positions.

[0082] The automatic installation device and method for roof anti-cold nails provided by the present invention have the following advantages:

[0083] 1. The present invention solves the problem that the aluminum alloy roof anti-cold nails cannot be automatically welded and need manual grinding, marking positioning and welding, and the manual welding is time-consuming.
