Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding equipment for parts used in mining machinery. Background Technology

[0002] In mining operations, a large amount of mining equipment is required for mine exploration and excavation. During the exploration process, steel pipes are driven into the ground to extract internal water and gas. When the steel pipes are damaged or insufficient in length during exploration and transportation, welding is required to facilitate reuse. Traditional steel pipe welding presents the following problems: First, welding is done manually with a handheld welding torch. This method requires skilled welders. Given the smooth cylindrical surface of the steel pipe, it is difficult for ordinary welders to rotate and weld it simultaneously. Alternatively, more manpower may be needed to manually clamp and rotate the pipe, which is time-consuming, labor-intensive, and very inconvenient.

[0003] In existing technologies, welding equipment in the form of a chassis is used to clamp and position pipe fittings to ensure alignment before welding. This can improve welding efficiency while ensuring welding alignment. However, this technology cannot meet the needs of welding multiple pipe sections. In actual pipe processing, the required length may necessitate welding multiple pipe sections. Outdoor welding equipment has limited length and may not be able to accommodate all pipes on the equipment. As a result, some pipes will be exposed. Without support, their own weight can easily cause misalignment of other pipe ends, affecting the welding effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a welding device for mining machinery parts to solve the problems mentioned in the background. This invention features a novel structure. Through the cooperation of a drive assembly, drive wheel, and auxiliary wheel, pipe fittings of different sizes are adjusted and limited, driving the pipe fittings to rotate for welding. With the cooperation of a moving assembly and a clamping assembly, the two welded pipe sections are pushed out of the welding position by clamping at the bottom and sides. A new pipe is added from the inlet end of the processing box to continue welding with one end of the original welded pipe. During this process, the moved pipe is clamped and supported to maintain a consistent axis with the newly fed pipe, thus avoiding interference with the welding result and improving welding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a welding equipment for parts in mining machinery, comprising a processing box, a base box fixed to the bottom of the processing box, an outer pull plate slidably installed inside the base box, movable wheels installed at the four corners of the bottom of the base box, two rows of drive wheels on both sides of the bottom of the processing box, a shaft fixed at the center of the shaft of the same row of drive wheels, and sliding seats rotatably installed at both ends of the shaft via bearings, a top frame fixed to the top of the processing box in the middle position, and a welding device installed on the top of the top frame, auxiliary wheels on both sides of the welding device, two sets of pipe fittings placed between the drive wheels and the auxiliary wheels, and the pipe fittings connecting to the bottom of the welding device, a drive assembly on one side of the inlet end of the processing box, the drive assembly including a drive shaft, and the processing box on both sides... A drive shaft is rotatably mounted on the inner wall via bearings, and a second motor is fixed on the outer wall of the processing box at the position corresponding to the drive shaft. The output end of the second motor is fixedly connected to the drive shaft. A driven bevel gear is fixed to one end of the drive wheel shaft facing the drive shaft. Two sets of driving bevel gears are sleeved on the surface of the drive shaft, and the driving bevel gears mesh with the driven bevel gears. Clamping assemblies are provided on the top of the outer pull plate and the inner walls of both sides of the processing box. The clamping assemblies include bottom extrusion plates. The processing box and the bottom box are located between the two sets of drive wheels and have a moving notch. Two bottom extrusion plates are symmetrically provided on the top of the outer pull plate, and the bottom extrusion plates are in extrusion contact with the bottom of the two pipes. A moving assembly is provided on the inner wall of the bottom of the bottom box. The moving assembly includes a moving frame, and the bottom of the outer pull plate slides along the inside of the moving frame.

[0006] Furthermore, the moving component also includes a one-way screw, which is rotatably mounted inside the moving frame via a bearing, and a moving plate is threaded onto the surface of the one-way screw. The moving plate slides along the inside of the moving frame, and the bottom of the outer pull plate is fixedly connected to the moving plate. A first motor is fixedly mounted at the bottom of the inlet end of the processing box, and the output end of the first motor is fixedly connected to the one-way screw.

[0007] Furthermore, the clamping assembly also includes slide rails. Slide rails are fixed on the inner walls of both sides of the processing box, and two sliders are symmetrically slidably installed inside the slide rails. The sliders and the bottom extrusion plate are on the same cross-section. Telescopic rods are fixed on the outer surface of the sliders, and side extrusion plates are fixed to the extended ends of the telescopic rods. Connecting plates are fixed to the extended ends of the two telescopic rods. A vertical frame is fixed to the outer end of the slider, and the bottom of the vertical frame is fixedly connected to the outer pull plate.

[0008] Furthermore, a connecting rod is rotatably mounted on one end of the connecting plate at the outlet end of the processing box via a rotating shaft, and the other end of the connecting rod is rotatably mounted on the side of the bottom extrusion plate via a rotating shaft. An electric push rod is fixed inside the outer pull plate at a position corresponding to the bottom extrusion plate, and the extended end of the electric push rod is fixedly connected to the bottom extrusion plate.

[0009] Furthermore, the movable notch, the bottom box, and the slide rail all have openings on one side of the processing box outlet, and the outer pull plate has two movable support legs fixed at the position corresponding to the opening of the bottom box.

[0010] Furthermore, the drive assembly also includes a sliding frame, with sliding frames fixed on the bottom inner walls of both ends of the processing box, and the sliding blocks at both ends of the shaft sliding along the corresponding sliding frame interiors, and the sliding frame on one side of the processing box outlet end is provided with an outlet outlet identical to the moving notch.

[0011] Furthermore, a bidirectional screw is rotatably mounted inside the slide frame at the inlet end of the processing box via a bearing, and the slide block is threaded onto the surface of the bidirectional screw. A third motor is fixed on the outer wall of the processing box at a position corresponding to the bidirectional screw, and the output end of the third motor is fixedly connected to the bidirectional screw.

[0012] Furthermore, the slide is mounted on the back of the driven bevel gear with a mounting bracket, and the other end of the mounting bracket is slidably sleeved on the drive shaft. The driving bevel gear is rotatably mounted on the mounting bracket via a bearing.

[0013] Furthermore, symmetrical protrusions are fixed on the surface of the drive shaft, and a groove is opened on the surface of the active bevel gear to slide and engage with the protrusions. The active bevel gear is slidably engaged and mounted on the surface of the drive shaft.

[0014] Furthermore, auxiliary wheels are installed on both sides of the top frame, the bottom of the auxiliary wheels slides in contact with the top of the pipe, and inserts are fixed on both sides of the auxiliary wheels, with the two ends of the inserts slidingly inserted into the inside of both sides of the processing box.

[0015] The beneficial effects of this invention are:

[0016] 1. In this invention, a cylinder drives the welding device and auxiliary wheel to move up and down. The brackets on both sides of the auxiliary wheel slide along the side of the processing box to guide the movement of the auxiliary wheel. The position of the welding device and the auxiliary wheel can be adjusted in conjunction with the movement of the drive wheel so that they can maintain contact with the top of the pipe and prevent the pipe from jumping up as the drive wheel rotates.

[0017] 2. In this invention, the second motor drives the drive shaft to rotate. Because the active bevel gear is engaged with the convex strip, it rotates together with the drive shaft. The active bevel gear meshes with the driven bevel gear, driving the drive wheels on both sides to rotate synchronously. During processing, the pipe is slowly rotated. Because the drive wheels at the bottom of the two sets of pipes are connected by a shaft, they rotate at the same speed, which can maintain the stability of welding. When dealing with pipes of different diameters, the third motor is turned on to drive the bidirectional screw to rotate. The slide of the shaft and the threaded engagement of the bidirectional screw slide along the slide frame. The mounting bracket drives the active bevel gear to slide along the surface of the drive shaft. Because the drive shaft is provided with convex strips on the top and bottom, the active bevel gear can move while maintaining the engagement relationship with the drive shaft.

[0018] 3. After the welding of the two pipe sections is completed, the electric push rod drives the bottom extrusion plate to contact the bottom of the two pipe sections. As the bottom extrusion plate passes through the moving notch, it drives the two connecting rods to rotate, pulling the connecting plate and the side extrusion plate to move towards the side of the pipe section. The telescopic rod extends until it extrudes and fixes the side of the pipe section, keeping the pipe section clamped and fixed on both sides and bottom. This facilitates the delivery of the pipe section out of the processing box via the moving component. The connecting rod can be telescopic, and its length can be adjusted when welding pipe sections of different diameters to ensure that the bottom extrusion plate and the side extrusion plate can extrude the side and bottom of the pipe section simultaneously.

[0019] 4. In this invention, the first motor is turned on to drive the one-way screw to rotate. The moving plate and the one-way screw are threaded together and move outward along the moving frame. At this time, the outer pull plate moves out of the bottom box and, together with the clamping assembly, pulls the welded pipe part out of the processing box, which is convenient for subsequent welding of the pipe.

[0020] 5. Compared with the prior art, the present invention, through the cooperation of the drive component, drive wheel and auxiliary wheel, adjusts and limits the pipe fittings of different sizes, and drives the pipe fittings to rotate for welding. With the cooperation of the moving component and the clamping component, the two sections of pipe that have been welded are pushed out of the welding position by the clamping action of the bottom and sides. A new pipe is added from the inlet end of the processing box and the welding work is continued to be completed with one end of the original welded pipe. In this process, the moved pipe is clamped and supported to keep it on the same axis as the newly fed pipe, so as not to interfere with the welding result and improve the welding efficiency.

[0031] Please see Figures 1 to 8This invention provides a technical solution: a welding equipment for parts of mining machinery, including a processing box 1, a bottom box 2 fixed to the bottom of the processing box 1, and an outer pull plate 3 slidably installed inside the bottom box 2. Moving wheels 21 are installed at the four corners of the bottom of the bottom box 2. Two rows of drive wheels 5 are provided on both sides of the bottom of the processing box 1. A shaft 51 is fixed at the axis of the same row of drive wheels 5. Slide seats 89 are rotatably installed at both ends of the shaft 51 via bearings. A top frame 11 is fixed to the top of the processing box 1 in the middle position, and a welding device 14 is installed on the top of the top frame 11. The welding device 14... Auxiliary wheels 13 are provided on both sides. Two sets of pipe fittings 4 are placed between the drive wheel 5 and the auxiliary wheels 13, and the pipe fittings 4 are connected to the bottom of the welding device 14. A drive assembly 8 is provided on one side of the inlet end of the processing box 1. The drive assembly 8 includes a drive shaft 82. The drive shaft 82 is rotatably mounted on the inner walls of both sides of the processing box 1 through bearings. A second motor 81 is fixed on the outer wall of the processing box 1 at the position corresponding to the drive shaft 82. The output end of the second motor 81 is fixedly connected to the drive shaft 82. A driven bevel gear 86 is fixed on the end of the shaft 51 of the drive wheel 5 facing the drive shaft 82. Two sets of driving bevel gears 85 are fitted onto the surface of 82, and the driving bevel gears 85 mesh with the driven bevel gears 86. Clamping assemblies 6 are provided on the top of the outer pull plate 3 and on the inner walls of both sides of the processing box 1. The clamping assembly 6 includes a bottom pressing plate 68. A moving notch 16 is provided between the processing box 1 and the bottom box 2, located between the two sets of drive wheels 5. Two bottom pressing plates 68 are symmetrically provided on the top of the outer pull plate 3, and the bottom pressing plates 68 are in pressing contact with the bottom of the two pipe fittings 4. A moving assembly 7 is provided on the inner wall of the bottom of the bottom box 2. The moving assembly 7 includes a moving frame 72. The bottom of the outer pull plate 3... Sliding along the inside of the movable frame 72, when using the device, the processing box 1 can be pushed to the use position by the movable wheel 21 at the bottom. After locking the movable wheel 21, the two pipe sections are first placed inside the processing box 1. The drive assembly 8 adjusts the position of the drive wheel 5 according to the diameter of the pipe 4. The bottom sides of the pipe 4 contact the drive wheel 5. The welding device 14 in the middle position welds the two pipe sections 4 at the joint position. After welding, the clamping assembly 6 clamps the bottom and sides of the two pipe sections 4. The movable assembly 7 sends part of the pipe section 4 out of the processing box 1 and sends in another set of new pipe sections 4 to complete the welding process when joining.

[0032] In this embodiment, the moving component 7 further includes a one-way screw 73. The one-way screw 73 is rotatably mounted inside the moving frame 72 via a bearing, and a moving plate 74 is threaded onto the surface of the one-way screw 73. The moving plate 74 slides along the inside of the moving frame 72. The bottom of the outer pull plate 3 is fixedly connected to the moving plate 74. A first motor 71 is fixedly mounted at the bottom of the inlet end of the processing box 1, and the output end of the first motor 71 is fixedly connected to the one-way screw 73. When the first motor 71 is turned on, it drives the one-way screw 73 to rotate. The moving plate 74 and the one-way screw 73 are threadedly engaged and move outward along the moving frame 72. At this time, the outer pull plate 3 moves out of the bottom box 2, and with the help of the clamping component 6, the welded pipe part 4 is pulled out of the processing box 1, which facilitates the subsequent welding of the pipe.

[0033] In this embodiment, the clamping assembly 6 further includes a slide rail 61. The slide rail 61 is fixed to the inner walls of both sides of the processing box 1, and two sliders 62 are symmetrically slidably installed inside the slide rail 61. The sliders 62 and the bottom extrusion plate 68 are on the same cross-section. A telescopic rod 63 is fixed to the outer surface of the slider 62, and a side extrusion plate 65 is fixed to the extended end of the telescopic rod 63. A connecting plate 64 is fixed to the extended ends of the two telescopic rods 63. A vertical frame 66 is fixed to the outer end of the slider 62, and the bottom of the vertical frame 66 is fixedly connected to the outer pull plate 3. A connecting rod 67 is rotatably mounted on the bottom of one end of the connecting plate 64 at the outlet end of the processing box 1 via a rotating shaft. The other end of the connecting rod 67 is rotatably mounted on the side of the bottom extrusion plate 68 via a rotating shaft. The outer pull plate 3 corresponds to the bottom extrusion plate inside. An electric push rod 69 is fixed at position 68, and the extended end of the electric push rod 69 is fixedly connected to the bottom extrusion plate 68. After the two pipe sections 4 are welded, the electric push rod 69 drives the bottom extrusion plate 68 to contact the bottom of the two pipe sections 4. As the bottom extrusion plate 68 passes through the moving notch 16, it will drive the two connecting rods 67 to rotate, pulling the connecting plate 64 and the side extrusion plate 65 to move to the side of the pipe section 4. The telescopic rod 63 extends until it extrudes and fixes the side of the pipe section 4, keeping the sides and bottom of the pipe section 4 clamped and fixed, so that the pipe section 4 can be sent out of the processing box 1 through the moving component 7. The connecting rod 67 can be telescopic, and the length can be adjusted when welding pipe sections 4 of different diameters to ensure that the bottom extrusion plate 68 and the side extrusion plate 65 can extrude the side and bottom of the pipe section 4 at the same time.

[0034] In this embodiment, the movable notch 16, the base box 2, and the slide rail 61 are all open on one side of the processing box 1 at the outlet end. The outer pull plate 3 has two movable support legs 31 fixed at the position corresponding to the opening of the base box 2. The notches of the movable notch 16, the base box 2, and the slide rail 61 facilitate the delivery of the outer pull plate 3 and the pipe 4 by clamping them with the bottom extrusion plate 68. The two movable support legs 31 of the outer pull plate 3 support the pull-out end of the pipe 4, keeping the pipe 4 on the same axis during the welding process.

[0035] In this embodiment, the drive assembly 8 further includes a sliding frame 87. Sliding frames 87 are fixed to the inner walls of the bottom at both ends of the processing box 1, and sliding seats 89 at both ends of the shaft 51 slide along the corresponding sliding frames 87. The sliding frame 87 on the outlet side of the processing box 1 has an outlet port identical to the moving notch 16. A bidirectional screw 88 is rotatably mounted inside the sliding frame 87 at the inlet end of the processing box 1 via a bearing, and the sliding seat 89 is threaded onto the surface of the bidirectional screw 88. A third motor 810 is fixed on the outer wall of the processing box 1 at a position corresponding to the bidirectional screw 88, and the output end of the third motor 810 is fixedly connected to the bidirectional screw 88. A mounting bracket 84 is mounted on the back of the driven bevel gear 86, and the other end of the mounting bracket 84 is slidably mounted on the drive shaft 82. The driving bevel gear 85 is rotatably mounted on the mounting bracket 84 via a bearing. A symmetrically fixed protrusion 83 is fixed on the surface of the drive shaft 82, and the surface of the driving bevel gear 85 has a protrusion 83 corresponding to the protrusion 83. 3. A sliding engagement groove is provided. The active bevel gear 85 is slidably engaged on the surface of the drive shaft 82. The pipe 4 is placed on the two drive wheels 5 on both sides. The second motor 81 drives the drive shaft 82 to rotate. Because the active bevel gear 85 is engaged with the protrusion 83, it will rotate together with the drive shaft 82. The active bevel gear 85 meshes with the driven bevel gear 86, driving the two drive wheels 5 on both sides to rotate synchronously. During the processing, the pipe 4 is driven to rotate slowly. Because the drive wheels 5 at the bottom of the two sets of pipe 4 are connected by the shaft 51, the rotation speed is the same, which can maintain the stability of welding. When facing pipe 4 with different diameters, the third motor 810 is turned on to drive the bidirectional screw 88 to rotate. The slide seat 89 of the shaft 51 and the bidirectional screw 88 are threaded together and slide along the slide frame 87. The mounting bracket 84 drives the active bevel gear 85 to slide along the surface of the drive shaft 82. Because the drive shaft 82 is provided with protrusions 83 on the top and bottom, the active bevel gear 85 can move while maintaining the engagement relationship with the drive shaft 82.

[0036] In this embodiment, auxiliary wheels 13 are installed on both sides of the top frame 11. The bottom of the auxiliary wheels 13 slides in contact with the top of the pipe fitting 4. Insert brackets 15 are fixed on both sides of the auxiliary wheels 13, and the two ends of the insert brackets 15 are slidably inserted into the inside of both sides of the processing box 1. The bottom position of the auxiliary wheels 13 is close to the welding end of the welding device 14. That is, when the auxiliary wheels 13 are in contact with the top of the pipe fitting 4, the welding device 14 can just weld the joint of the two sets of pipe fittings 4. The cylinder 12 drives the welding device 14 and the auxiliary wheels 13 to move up and down. The insert brackets 15 on both sides of the auxiliary wheels 13 slide along the side of the processing box 1 to guide the movement of the auxiliary wheels 13. The position of the welding device 14 and the auxiliary wheels 13 can be adjusted in conjunction with the movement of the drive wheel 5 so that they can maintain contact with the top of the pipe fitting 4 and prevent the pipe fitting 4 from jumping during the rotation of the drive wheel 5.

[0037] When using the device, the processing box 1 can be pushed to the working position by the bottom moving wheels 21. After locking the moving wheels 21, first put the two pipe sections into the processing box 1, and place the pipe fittings 4 on the two drive wheels 5 on both sides. The second motor 81 drives the drive shaft 82 to rotate. Because the active bevel gear 85 is engaged with the convex strip 83, it will rotate together with the drive shaft 82. The active bevel gear 85 meshes with the driven bevel gear 86, driving the drive wheels 5 on both sides to rotate synchronously. During the processing, the pipe fittings 4 are driven to rotate slowly because the two sets of pipe fittings 4 at the bottom of the drive shaft 82 rotate slowly. The driving wheel 5 is connected by the shaft 51, so they rotate at the same speed, maintaining welding stability. When dealing with pipe fittings 4 of different diameters, the third motor 810 is activated to drive the double-acting screw 88 to rotate. The slide seat 89 of the shaft 51 and the double-acting screw 88 are threaded together and slide along the slide frame 87. The mounting bracket 84 drives the driving bevel gear 85 to slide along the surface of the drive shaft 82. Because the drive shaft 82 has protrusions 83 on its upper and lower parts, the driving bevel gear 85 can move while maintaining a snap-fit ​​relationship with the drive shaft 82. The bottom sides of the pipe fitting 4 contact the driving wheel 5, which is controlled by the cylinder. 12 drives the welding device 14 and auxiliary wheel 13 to move up and down. The brackets 15 on both sides of the auxiliary wheel 13 slide along the side of the processing box 1 to guide the movement of the auxiliary wheel 13. It can be used in conjunction with the movement of the drive wheel 5 to adjust the position of the welding device 14 and the auxiliary wheel 13 so that they can keep in contact with the top of the pipe fitting 4. The pipe fitting 4 is kept from jumping as it rotates with the drive wheel 5. The electric push rod 69 drives the bottom extrusion plate 68 to contact the bottom of the two pipe fittings 4. As the bottom extrusion plate 68 passes through the moving notch 16, it will drive the two connecting rods 67 to rotate. Pull the connecting plate 64 and the side extrusion plate 65 to move towards the side of the pipe fitting 4. The telescopic rod 63 extends until it extrudes and fixes the side of the pipe fitting 4, keeping the pipe fitting 4 clamped and fixed on both sides and bottom. This makes it easy to send part of the pipe fitting 4 out of the processing box 1 through the moving component 7. Turn on the first motor 71 to drive the one-way screw 73 to rotate. The moving plate 74 and the one-way screw 73 are threaded together and move outward along the moving frame 72. At this time, the outer pull plate 3 moves out of the bottom box 2 and, together with the clamping component 6, pulls the welded part of the pipe fitting 4 out of the processing box 1, which is convenient for subsequent welding of the pipe.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
