[0002] Hydraulic support is a commonly used structure in coal mining. It is usually installed by multi-layer and multi-pass welding in the manufacturing process. The multi-layer and multi-pass welding method can effectively improve the strength of the welded part. Hydraulic support welding includes strip and ring welding (strip welding such as frame structure welding, ring welding such as hydraulic cylinder and support rod, hydraulic cylinder and frame structure connection parts);

[0003] Traditional welding is to perform multi-layer and multi-pass welding by hand-held welding guns. This method places great demands on welding workers. Nowadays, corresponding welding devices are used for corresponding welding.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Reference Figure 1-Figure 11 A multi-layer and multi-channel hydraulic support welding device includes a base plate 1, a vertical rod 2 is fixedly installed on the base plate 1, and a base 3 is fixedly installed at the lower end of the vertical rod 2; the vertical rod 2 can also be replaced by a rod body with an adjustment function, such as an electric push rod, or it can be composed of two rod bodies with matching threads, and the two rod bodies are threadedly connected (one rod body is an external thread, and the other rod body is hollow inside and is provided with a matching external thread), so as to adjust the height of the base plate 1 when it is used as a whole, and also to reduce the space occupied by the placement when not in use; the shape of the base 3 can be selected according to the required use environment, Figure 1As shown, the length of the base 3 is perpendicular to the width direction of the base plate 1, and the lower end of the vertical rod 2 and the base 3 can also be set to a rotation method with a self-locking function (such as a threaded connection), so that when necessary, the length of the base 3 can be made flush with the width direction of the base plate 1.

[0045] A servo motor 1 4 is fixedly mounted on the back side of the base plate 1 (for ease of understanding, the side where the arc-shaped rotating seat 35 is located is named as the back side, and the other side is the front side), a ball screw 5 is fixedly mounted on the driving end of the servo motor 1 4, and the ball screw 5 rotates through the base plate 1 and is fixedly mounted with a stopper 1, a moving seat 7 is mounted on the ball screw 5 through a ball nut 6 (and the diameter of the stopper 1 is greater than the height of the moving seat 7), and clamping grooves 16 are symmetrically opened on both sides of the moving seat 7;

[0046] The front side of the base plate 1 is provided with an arc groove 8, in which a limit block 9 is slidably installed (refer to Figure 4 , here the limit block 9 is composed of two cylindrical fixed parts with different diameters), and the lower end of the arc groove 8 is cylindrical, and its size is equal to the maximum diameter of the limit block 9, so that when it is at the lowest point, the limit block 9 can be moved out of the arc groove 8 (the premise of moving out is that the limit block 9 is subjected to a large external force. In order to ensure that it will not move when it is not subjected to a large external force, the limit block 9 can be made of metal or magnetic material, and then an installation groove is opened on the bottom wall of the lower end of the arc groove 8, and then an object that can be attracted to the limit block 9, such as a magnet, is set in the installation groove, and the friction resistance can also be increased);

[0047] A mounting frame 10 (similar to a U shape) is fixedly installed at one end of the limit block 9. The mounting frame 10 includes two round blocks and a fixed cross block. The cross block is fixed between the two round blocks. Two shaft rods 12 are rotatably installed between the two round blocks. The two shaft rods 12 are fixedly installed with meshing transmission gears 13. A servo motor 2 14 is fixedly installed on one of the round blocks, and one end of the corresponding shaft rod 12 is fixed on the driving end of the servo motor 2 14. A clamping frame 15 that matches the clamping groove 16 is fixedly sleeved on the two shaft rods 12; when the servo motor 2 14 is working, with the cooperation of the transmission gear 13, the two shaft rods 12 can drive the corresponding clamping frames 15 to move toward each other (approach each other or move away from each other), thereby completing the clamping fixation or separation with the moving seat 7.

[0048] Reference Figure 1-Figure 11A disc 11 is fixedly mounted on the lower end surface of the mounting frame 10, an electric telescopic rod 17 is fixedly mounted on the lower surface of the disc 11, a disc 2 18 is fixedly mounted on the lower end of the electric telescopic rod 17, and two short plates are fixedly mounted on the lower surface of the disc 2 18, an angle adjustment motor 19 is fixedly mounted on the outer side of one of the short plates, a rotating rod is fixedly mounted on the driving end of the angle adjustment motor 19, one end of the rotating rod rotates through the short plate and is rotatably mounted on the outer side of the other short plate, a mounting seat is fixedly mounted on the rotating rod, a welding gun 20 is fixedly mounted on the lower surface of the mounting seat, and the spacing between the upper surface of the mounting seat and the lower surface of the disc 2 18 must meet the requirements for the normal rotation of the mounting seat with the rotating rod.

[0049] Reference Figure 1-Figure 11 A change-of-direction hole 21 is provided on the base plate 1, and the upper end of the arc groove 18 is connected to the change-of-direction hole 21, and a rotating disk 23 is rotatably installed on the change-of-direction hole 21 through a damping shaft (a damping shaft can be specifically provided, which is not shown in the figure, and is specifically provided at the lower end of the rotating disk 23, and the upper end of the rotating disk 23 is used for cooperating with the tightening screw 22 for use), and a plurality of limiting holes 25 are provided on the rotating disk 23, and a limiting rod 26 is slidably installed on each limiting hole 25, and a movable disk 24 is fixedly installed on one end of the plurality of limiting rods 26, and a stopper 2 is fixedly installed on the other end of each limiting rod 26; the large size of the rotating disk 23 and the movable disk 24 The two have the same small shape, and it is not easy to slide between them when not subject to a large external force. Specifically, the friction resistance between the limiting hole 25 and the limiting rod 26 can be increased, or an annular magnetic block is arranged between the rotating disk 23 and the movable disk 24, and the sides of the two annular magnetic blocks that are close to each other attract each other; an arc groove 27 matching the arc groove 1 8 is provided on the movable disk 24, and the upper end of the arc groove 27 and the lower end of the arc groove 1 8 are arranged in the same way, the end faces of the arc groove 1 8 and the arc groove 27 are both stepped, and the radii of the two are the same, and the arc centers overlap, so that the limiting block 9 can slide along the arc groove 1 8 to the arc groove 27.

[0050] An elastic pad 30 that matches the direction-changing hole 21 is fixedly provided on the outside of the rotating disk 23. The elastic pad 30 has a notch to meet the matching use of the arc groove 1 8 and the arc groove 27, and the maximum diameter of the limit block 9 is greater than the width of the notch, thereby ensuring that the limit block 9 can slide smoothly along the arc groove 1 8 to the arc groove 27, and at the same time, the outer wall of the moving disk 24 fits with the inner wall of the elastic pad 30; the purpose of setting the elastic pad 30 is to enable the rotating disk 23 to rotate on the direction-changing hole 21, and the two are in Figure 1 In the state shown, it is in a tightly fitting state.

[0051] A threaded hole connected to the direction-changing hole 21 is provided on the base plate 1, and a tightening screw 22 is threadedly installed on the threaded hole. The lower end of the tightening screw 22 cooperates with the rotating disk 23, and a stopper 3 is fixedly installed on the upper end of the tightening screw 22. The setting of the stopper 3 is convenient for applying a rotational force to the tightening screw 22 by hand, so that the lower end of the tightening screw 22 moves up or down (upward movement is separated from the rotating disk 23, and downward movement is tightened against the rotating disk 23) (the lower end of the tightening screw 22 can specifically be against the elastic pad 30, or a hole is provided on the elastic pad 30, so that the lower end of the tightening screw 22 can pass through the hole and directly contact the rotating disk 23);

[0052] The damping shaft can be specifically arranged in the middle position of the changing hole 21. At this time, the thickness of the rotating disk 23 and the movable disk 24 can be the same, or the thickness of the rotating disk 23 is greater than the thickness of the movable disk 24. When the thickness is the same, only half of the end of the damping shaft away from the changing hole 21 is fixedly connected to the rotating disk 23, and the other half is fitted with the movable disk 24. When the thickness of the rotating disk 23 is greater than the thickness of the movable disk 24, the difference in thickness between the two can be greater than or equal to the diameter of the damping shaft, so that the end of the damping shaft away from the changing hole 21 is completely fixed to the rotating disk 23.

[0053] The setting of the limit rod 26 and the second stopper must be able to rotate to the other side of the base plate 1 with the rotation of the rotating disk 23. The diameter of the movable disk 24 can be increased to meet the above operation, or the limit rod 26 can be set as a retractable multi-section rod body, and springs are arranged between the multi-section rod bodies. In the initial state, the limit rod 26 is in the shortest position. When in use (the movable disk 24 moves relative to the rotating disk 23), the multiple rod bodies will be extended, thereby meeting the movement of the movable disk 24 after rotation;

[0054] A vertical step groove 28 is also provided on the movable plate 24, on which a step block is slidably installed (the end face shape of the vertical step groove 28 is also stepped), and a sliding block 29 that cooperates with the mounting frame 10 is fixedly installed at one end of the step block (when the mounting frame 10 moves to the arc groove 27 along with the limit block 9, the sliding block 29 contacts the inner side of the round block that fits the base plate 1, thereby limiting and blocking it); the friction between the vertical step groove 28 and the step block can also be increased so that the sliding block 29 can overcome the effect of gravity and stay at any position after moving to that position.

[0055] Reference Figure 1-Figure 11, an arc-shaped support seat 33 is fixedly installed on the back of the base plate 1 through a plurality of fixing rods 32, an arc-shaped support groove 34 is provided on the outer side and the inner side of the arc-shaped support seat 33, an arc-shaped body matching therewith is slidably installed on each of the two arc-shaped support grooves 34, and an arc-shaped rotating seat 35 is fixedly installed on the two arc-shaped bodies (not shown in the figure) together (the arc-shaped rotating seat 35 has an arc-shaped groove matching the arc-shaped support seat 33 on the side close to the base plate 1, and the arc-shaped body is fixed on the inner wall of the arc-shaped groove);

[0056] The arc-shaped support groove 34 and the arc-shaped rotating seat 35 are both set in an optimal arc. The arc-shaped rotating seat 35 will rotate under the action of external force (the rotating motor 38 is used as a power source). During the rotation process, the arc-shaped rotating seat 35 will not be completely separated from the arc-shaped support groove 34. A rotating seat 37 is fixedly installed on the arc-shaped rotating seat 35 by a short rod 36, and clamping grooves 16 that cooperate with the upper end of the clamping frame 15 are also opened on both sides of the rotating seat 37.

[0057] Reference Figure 1-Figure 11 A rotating motor 38 is fixedly installed on the back of the base plate 1. A shaft 39 is installed on the driving end of the rotating motor 38 and the back of the base plate 1. A transmission structure 40 is installed between the two shafts 39. With the cooperation of the transmission structure 40, the rotating motor 38 can make the two shafts 39 rotate simultaneously when it is working. A gear 41 is fixedly installed on the two shafts 39. An arc-shaped gear ring 31 that meshes with the two gears 41 at the same time is fixedly installed on the arc-shaped rotating seat 35. The arc-shaped gear ring 31 is a superior arc, which ensures that it can always mesh with one gear 41 (the figure shows a state of meshing with both gears 41);

[0058] The transmission structure 40 can be specifically a chain transmission structure or a belt transmission structure. Both transmission structures are prior arts, each with its own advantages, and can be selected and used according to specific circumstances.

[0059] The distance between the above-mentioned arc-shaped rotating seat 35 and the base plate 1 is constant, and the distance between the two can also be set to be adjustable. For example, the fixed rod 32 is replaced by a component with a telescopic function such as an electric push rod. At this time, it should be noted that the position of the rotating motor 38, the shaft 39, the transmission structure 40, and the gear 41 must move with the arc-shaped rotating seat 35 to ensure that the gear 41 is always engaged with the arc-shaped gear ring 31. At this time, an electric push rod is also used to drive a moving block, and the rotating motor 38 and the other shaft 39 can be installed on the side of the moving block away from the electric push rod.

[0060] A micro servo motor can be used to drive the rotation of the rotating disk 23 instead of manual operation, so there is no need to set the tightening screw 22 at this time; at this time, the arc groove 1 8 and the arc groove 2 27 are set as electric slide rails, thereby driving the limit block 9 to slide thereon, which part is the prior art and is not elaborated in detail here; the movement of the movable disk 24 relative to the rotating disk 23 can also be automatically operated, such as setting an electric push rod between the rotating disk 23 and the movable disk 24, or setting a matching magnet on the side where the rotating disk 23 and the movable disk 24 are in contact, and two magnets are symmetrically arranged on the rotating disk 23 and the movable disk 24, and the two magnets on the rotating disk 23 are opposite in magnetism to the side of the movable disk 24, and the two magnets on the movable disk 24 are opposite in magnetism to the side of the rotating disk 23, and a connecting rod is fixed between the two magnets on the rotating disk 23, and the connecting rod is driven by a motor (rotating 180° each time).

[0061] The above-mentioned electrical components (such as servo motor 1 4, electric telescopic rod 17, etc.) can be used in conjunction with a controller for unified control when in use; servo motor 1 4, servo motor 2 14 and rotary motor 38 all need to select motors with self-locking function, which is specifically the existing technology, or a brake is added to the shaft (ball screw 5, shaft 12, shaft body 39) used therewith, which is also the existing common technology and will not be elaborated on here.

[0062] The naming of the above technical features is for ease of understanding, and functional names are used. For example, the rotating disk 23 is a disk-shaped structure that can rotate on the base disk 1, and the remaining structures are not described in detail here.

[0063] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0064] The specific working principle of the present invention is as follows:

[0065] Strip multi-layer multi-pass welding: Figure 1 The welding gun 20 shown is located below the moving seat 7, and is used to perform multi-layer and multi-pass welding in the length direction. The servo motor 4 and the welding gun 20 are turned on, and the welding gun 20 works to weld. The servo motor 4 drives the moving seat 7 to reciprocate along the length direction of the ball screw 5 through the cooperation of the ball screw 5 and the ball nut 6, so as to perform welding. After the first welding is completed, the angle of the welding gun 20 can be changed by turning on the angle adjustment motor 19, so as to facilitate subsequent welding.

[0066] Strip welding is switched to ring welding: At this time, the limit block 9 is located at the lower end of the arc groove 1 8, and then the two clamping frames 15 are controlled by the servo motor 2 14 to rotate (move away from each other), thereby separating from the moving seat 7, and then the operator drives the relevant part of the mounting frame 10 by hand ( Figure 4 All shown) slide along the arc groove 1 8 and slide into the arc groove 2 27 (the lower end of the welding gun 20 is facing downward during this process), at this time, the part where the mounting frame 10 is in contact with the base plate 1 will not be separated from the movable plate 24 under the limiting effect of the sliding block 29;

[0067] An upward rotational force is applied to the clamping screw 22 by hand to release the clamping state of the clamping screw 22 on the rotating disk 23, and then a rotational force is applied to the rotating disk 23 or the movable disk 24 by hand (specifically, the force can be applied by holding the mounting frame 10 by hand) to rotate the part 180° (turn over), and then a pulling force away from the rotating disk 23 is applied to the movable disk 24. When the stopper block 2 is in contact with the rotating disk 23, the clamping frame 15 moves to the bottom of the rotating seat 37. At this time, the servo motor 2 14 works in the reverse direction so that the upper ends of the two clamping frames 15 are clamped to the rotating seat 37, and then an upward force is applied to the sliding block 29, and a pushing back force is applied to the movable disk 24.

[0068] Annular multi-layer and multi-pass welding: Turn on the rotating motor 38. The rotating motor 38 works through the cooperation of the shaft 39 and the transmission structure 40 to drive the two gears 41 to rotate at the same time. The rotation of the two gears 41 can ensure the rotation of the arc gear ring 31 (the arc gear ring 31 will always be meshed with at least one gear 41). The rotation of the arc gear ring 31 drives the arc swivel seat 35 to rotate in a circle. During the rotation process, the arc swivel seat 35 will drive the welding gun 20 to rotate together through the rotating seat 37. The welding gun 20 works during the rotation process of the arc swivel seat 35 to perform the required welding. The specific multi-layer and multi-pass welding operation method has been described above and will not be elaborated here.
