Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and particularly to a welding equipment for manufacturing temporary piers. Background Art

[0002] During the construction of steel box girder temporary piers, welding is an important link to ensure the structural stability and bearing capacity of the piers. During the installation of the piers, first determine the position and height of the piers, then carry out the foundation construction, then install the columns and crossbeams of the piers, and finally carry out the welding and fastening work. During the welding of the piers of the viaduct, as the welding height of the column body changes, the center of gravity of the lifting equipment rises. At this time, the stability of the lifting equipment is poor, which may affect the welding accuracy and the safety of welding operations. Moreover, the harmful gases and fumes generated during welding may affect the operators or the surrounding environment.

[0003] For example, a welding positioning device for steel box girder parts with the publication number of CN221755143U includes a working box, four legs symmetrically arranged on the bottom of the working box, a part body, and also includes two clamping components symmetrically arranged on the top of the working box. The part body can be clamped between the two clamping components. A spacing adjustment component is also arranged in the working box and is used in cooperation with the two clamping components. The spacing adjustment component can adjust the distance between the two clamping components, so as to realize the clamping and positioning of part bodies with different lengths. However, for the welding of the piers of the viaduct, when welding the column and crossbeam components at high places, it is not convenient to correspondingly improve the stability of the lifting equipment, reducing the welding accuracy and the welding safety of the operators. Moreover, it is not convenient to timely treat the harmful gases and fumes generated during welding, and there are certain limitations.

One side of the gear away from the winding sleeve is eccentrically fixedly connected with a limiting rod. Two clamping seats are symmetrically fixedly connected up and down on the other side inside the side groove. The limiting rod is clamped with the clamping seat;

[0011] Vertical grooves are symmetrically opened inside the fixed column. The vertical grooves are communicated with the three side grooves. A pull rope is wound around the outside of the winding sleeve. Transverse cylinders are symmetrically fixedly connected to both sides of the lower part of the fixed column. The number of each side of the transverse cylinders is the same as that of the side grooves. A sliding groove is opened on one side of the fixed column close to the transverse cylinder. An inner rod is slidably connected inside the transverse cylinder. One end of the pull rope away from the winding sleeve passes through the vertical groove and the sliding groove and is fixedly connected with the inner rod;

[0012] A fixed ring is fixedly connected inside the transverse cylinder. A spring is fixedly installed between the fixed ring and the inner rod. The spring is initially in a compressed state.

The tightening bolts are abutted against the sliding cylinders. The number of the negative pressure suction devices is the same as that of the sliding cylinders. The number of the tightening bolts is the same as that of the sliding cylinders.

[0014] By adopting the above technical solution, when the telescopic end of the hydraulic lifting rod drives the support plate and the enclosure to rise, it will also drive the arc-shaped block and the toothed plate to rise.

The clamping seat is made of magnet material, the limiting rod is made of iron material, and the limiting rod is magnetically connected to the clamping seat.

[0016] By adopting the above technical solution, the clamping seat is made of magnet material and the limiting rod is made of iron material, so that the limiting rod and the clamping seat are adsorbed and fixed.

[0018] By adopting the above technical solution, the winding sleeve releases the winding of the pulling rope. The spring is initially in a compressed state. At this time, the elastic force of the spring drives the inner rod to approach the side block. The inner rod pulls the pulling rope, and the pulling rope slides inside the vertical groove and the sliding groove, facilitating the clamping of the plug connector.

[0019] Preferably, the plug connector is snap-fitted with the slot, the number of the slots is the same as that of the plug connectors and the positions correspond one by one, and all three pulling ropes are slidably connected to the vertical groove.

The positioning strip is slidably connected to the limit frame, and the positioning strip is in contact with the inner side of the limit frame.

[0024] By adopting the above technical solution, rotate the double-headed lead screw on this side, and the limit frame limits the positioning strip, so that the two positioning strips approach each other until the two positioning strips clamp the cross beam body, which is convenient for maintaining the horizontal positioning welding of the cross beam body.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. An adjustment component is provided. When welding the vertical column body and the cross beam body at a high place, the operator climbs to the top of the support plate by using a ladder. At this time, multiple hydraulic lifting rods are started to work. The telescopic end of the hydraulic lifting rod drives the support plate and the enclosure to rise, and the telescopic end of the hydraulic lifting rod also drives the arc-shaped block and the toothed plate to rise. The toothed plate first meshes with the lowermost gear, and when the toothed plate contacts and then separates from the gear, it will exactly drive the gear to rotate half a turn. The gear drives the limit rod to pop out from the upper clamping seat. The clamping seat is made of magnetic material, and the limit rod is made of iron material, so that the limit rod and the clamping seat are adsorbed and fixed. The rotation of the gear will also drive the winding sleeve to rotate, and the winding sleeve releases the winding of the pulling rope. The spring is initially in a compressed state. At this time, the elastic force of the spring drives the inner rod to approach the side block, and the inner rod pulls the pulling rope. The pulling rope slides inside the vertical groove and the sliding groove. When the limit rod is stuck in the lower clamping seat, the inner rod drives the plug connector to exactly fit into the slot completely, thereby improving the connection strength between the hydraulic lifting rod and the fixed column and the support stability of the support plate. When the hydraulic lifting rod drives the arc-shaped block to descend, the toothed plate drives the gear to reverse and reset. The limit rod is stuck in the upper clamping seat, the pulling rope is wound by the winding sleeve, and the pulling rope drives the plug connector to reset. The multiple gears provided will be sequentially driven as the height of the arc-shaped block rises, so that the plug connectors are sequentially clamped in the slots from bottom to top, so as to adapt to the lifting height of the support plate and sequentially superimpose the support stability, reducing the problem that the center of gravity rises during lifting and affecting the support stability, and solving the problem that it is not convenient to correspondingly improve the stability of the lifting equipment when welding the vertical column and the cross beam components at a high place, reducing the welding accuracy and the welding safety of the operator;

[0031] 2. A positioning component is provided. After the height adjustment is completed, the operator starts the electric push rod. The electric push rod drives the clamping block to tightly press against the vertical column body, which is convenient for positioning the vertical column body. Then, the cross beam body is kept between the two positioning strips on the same side, and the double-headed lead screw on this side is rotated. The limit frame limits the positioning strips, so that the two positioning strips approach each other until the two positioning strips clamp the cross beam body, which is convenient for maintaining the horizontal positioning welding of the cross beam body, improving the welding stability. And when the operator welds through the welding equipment, the exhaust fan is started to work. The exhaust fan extracts air through the extraction pipe and the extraction hood, which is convenient for extracting the smoke and dust generated by welding and temporarily storing them in the dust collection box, improving the convenience of welding;

[0032] 3. A sliding cylinder, a negative pressure suction device and a tightening bolt are provided. When the vehicle frame body moves to the use position, the operator loosens the tightening bolt to adjust the position of the sliding cylinder, so that the suction cup at the bottom of the sliding cylinder adsorbs and fixes to the ground. Then, the tightening bolt is tightened to fix the sliding cylinder. The negative pressure suction device is started to pump air into the inside of the sliding cylinder and the suction cup, which is convenient for keeping the suction cup in a negative pressure state, improving the adsorption effect of the suction cup and the stability of the device when it is stationary, and facilitating subsequent precise welding.

A toothed plate 84 is fixedly connected to the inner side of the inner groove 83.

[0052] There are three side grooves 86. One side inside the side groove 86 is rotatably connected with a rotating shaft 87. A winding sleeve 88 is fixedly connected to the outer side of the rotating shaft 87. A gear 89 is fixedly connected to the side of the winding sleeve 88 away from the rotating shaft 87.

[0053] The arc-shaped block 82 is slidably connected with the fixed column 85. The rotating shaft 87 is horizontally arranged. The winding sleeve 88 and the gear 89 are both located inside the side groove 86. The gear 89 protrudes outside the side groove 86 for smooth meshing with the toothed plate 84. The clamping seat 811 is made of magnetic material, and the end stop rod 810 is made of iron material. The end stop rod 810 is magnetically connected with the clamping seat 811.

[0054] Vertical grooves 812 are symmetrically opened inside the fixed column 85. The vertical grooves 812 are communicated with all three side grooves 86. A pull rope 813 is wound around the outer side of the winding sleeve 88. Two cross cylinders 814 are symmetrically fixedly connected to the lower sides of both sides of the fixed column 85. The number of each side cross cylinder 814 is the same as that of the side groove 86. A sliding groove 815 is opened on one side of the fixed column 85 close to the cross cylinder 814. An inner rod 816 is slidably connected inside the cross cylinder 814. One end of the pull rope 813 away from the winding sleeve 88 passes through the vertical groove 812 and the sliding groove 815 and is fixedly connected with the inner rod 816.

[0055] A fixed ring 817 is fixedly connected inside the cross cylinder 814. A spring 818 is fixedly installed between the fixed ring 817 and the inner rod 816. The spring 818 is initially in a compressed state. The pull rope 813 is slidably connected with the fixed ring 817. One side of the inner rod 816 away from the fixed column 85 is fixedly connected with a plug connector 819. A side block 820 is fixedly connected to the outer side of the sleeve part of the hydraulic lifting rod 5. A slot 821 is opened on one side of the side block 820 close to the fixed column 85.

[0056] The vertical groove 812 is communicated with the sliding groove 815. The number of the sliding grooves 815 is the same as that of the cross cylinders 814. The spring 818 is slidably connected with the cross cylinder 814. One end of the spring 818 is fixedly connected with the inner rod 816, and the other end of the spring 818 is fixedly connected with the fixed ring 817.

[0057] The plug connector 819 is snap-fitted to the slot 821. The number of slots 821 is the same as that of the plug connectors 819, and their positions correspond one by one. All three draw ropes 813 are slidably connected to the vertical groove 812.

[0058] Example 1: As Figures 1-10 shown, when welding the high column body 1 and the cross beam body 2, the driving device at the bottom of the vehicle frame body 3 drives the traveling wheels 10 to travel to the use position. The operator loosens the fastening bolt 13 to adjust the position of the sliding cylinder 11, so that the suction cup at the bottom of the sliding cylinder 11 adsorbs and fixes to the ground. Then, the fastening bolt 13 is tightened to fix the sliding cylinder 11. The negative pressure suction device 12 is started to pump air into the inside of the sliding cylinder 11 and the suction cup, which is convenient for keeping the suction cup in a negative pressure state, improving the adsorption effect of the suction cup and the stability of the device when it is stationary, and facilitating subsequent precise welding.

[0059] The operator climbs to the top of the support plate 6 by using a ladder. At this time, multiple hydraulic lifting rods 5 are started to work. The telescopic ends of the hydraulic lifting rods 5 drive the support plate 6 and the enclosure 7 to rise. Moreover, the telescopic ends of the hydraulic lifting rods 5 also drive the arc-shaped block 82 and the toothed plate 84 to rise. The toothed plate 84 first meshes with the lowermost gear 89. When the toothed plate 84 comes into contact with the gear 89 and then separates from the gear 89, it will exactly drive the gear 89 to rotate half a turn. The gear 89 drives the limiting rod 810 to pop out from the upper clamping seat 811. The clamping seat 811 is made of a magnetic material, and the limiting rod 810 is made of an iron material, so that the limiting rod 810 and the clamping seat 811 are adsorbed and fixed to each other.

[0060] The rotation of the gear 89 will also drive the winding sleeve 88 to rotate. The winding sleeve 88 releases the winding of the draw rope 813. The spring 818 is initially in a compressed state. At this time, the elastic force of the spring 818 drives the inner rod 816 to approach the side block 820. The inner rod 816 pulls the draw rope 813, and the draw rope 813 slides inside the vertical groove 812 and the sliding groove 815. When the limiting rod 810 is stuck in the lower clamping seat 811, the inner rod 816 drives the plug connector 819 to exactly and completely fit into the inside of the slot 821, thereby improving the connection strength between the hydraulic lifting rod 5 and the fixed column 85 and the support stability for the support plate 6.

[0061] When the hydraulic lifting rod 5 drives the arc-shaped block 82 to descend, the toothed plate 84 drives the gear 89 to reverse and reset. The limit rod 810 is stuck in the upper clamping seat 811, the pulling rope 813 is wound by the winding sleeve 88, and the pulling rope 813 drives the plug connector 819 to reset. A plurality of gears 89 provided will be sequentially driven as the height of the arc-shaped block 82 rises, so that the plug connector 819 is sequentially clamped in the slot 821 from bottom to top, thereby being able to adapt to the lifting height of the support plate 6, perform sequential superposition of support stability, reduce the problem that the center of gravity rises during lifting and affects the support stability, and solve the problem that it is not convenient to correspondingly improve the stability of the lifting equipment when welding the column and beam components at high places, reducing the welding accuracy and the welding safety of the operator.

[0062] A positioning component 9 is arranged on the top of the support plate 6. The positioning component 9 includes an electric push rod 91 and a clamping block 92. The electric push rod 91 is horizontally and fixedly installed on the back side of the inner wall of the enclosure 7. The telescopic end of the electric push rod 91 is fixedly connected to the clamping block 92, and the clamping block 92 is attached to the column body 1.

[0063] Double-headed lead screws 93 are symmetrically and rotatably connected to the top of the support plate 6. Limit frames 94 are also symmetrically and fixedly connected to the top of the support plate 6. A positioning strip 95 is threadedly connected to the outside of the double-headed lead screw 93. The positioning strip 95 is slidably connected to the limit frame 94, and the positioning strip 95 is attached to the inner side of the limit frame 94.

[0064] Dust collection boxes 14 are also symmetrically and fixedly installed inside the support plate 6. The two dust collection boxes 14 are located outside the two limit frames 94. An exhaust fan 15 is fixedly installed on the top of the dust collection box 14. The model of the exhaust fan 15 is RAETTS70.

[0065] The outlet end of the exhaust fan 15 is connected to the dust collection box 14 through a pipeline. The inlet end of the exhaust fan 15 is connected with a suction pipe 96. A suction hood 97 is fixedly installed on the side of the suction pipe 96 away from the exhaust fan 15. The side of the suction pipe 96 close to the suction hood 97 is fixedly installed on the positioning strip 95 through a clamping block.

[0066] Embodiment 2: As Figures 11-14 shown, after height adjustment, the operator starts the electric push rod 91. The electric push rod 91 drives the clamping block 92 to press against the column body 1, which is convenient for positioning the column body 1. Then, with the beam body 2 kept between the two positioning strips 95 on the same side, the double-headed lead screw 93 on this side is rotated. The limit frame 94 limits the positioning strip 95, so that the two positioning strips 95 approach each other until the two positioning strips 95 clamp the beam body 2, which is convenient for maintaining the horizontal positioning welding of the beam body 2, improving the welding stability. And when the operator welds with a welding device, the exhaust fan 15 is started to work. The exhaust fan 15 sucks air through the suction pipe 96 and the suction hood 97, which is convenient for extracting the fumes and dust generated during welding and temporarily storing them in the dust collection box 14, improving the convenience of welding.

[0067] Working principle: When using this device, first, as Figures 1-14 shown, when the vehicle frame body 3 moves to the use position, the operator adjusts the suction cup at the bottom of the sliding cylinder 11 to adsorb and fix to the ground, starts the negative pressure suction device 12 to pump air into the inside of the sliding cylinder 11 and the suction cup, which is convenient for subsequent precise welding. The operator climbs to the top of the support plate 6 by using a ladder. At this time, start multiple hydraulic lifting rods 5 to work. The telescopic ends of the hydraulic lifting rods 5 drive the support plate 6 and the enclosure 7 to rise, and the telescopic ends of the hydraulic lifting rods 5 also drive the arc-shaped block 82 and the toothed plate 84 to rise. The toothed plate 84 first meshes with the lowermost gear 89, and the inner rod 816 drives the plug connector 819 to exactly fit into the inside of the slot 821, thereby improving the connection strength between the hydraulic lifting rod 5 and the fixed column 85 and the support stability of the support plate 6. Multiple gears 89 will be sequentially driven as the height of the arc-shaped block 82 rises, so that the plug connector 819 is sequentially clamped in the slot 821 from bottom to top, so as to adapt to the lifting height of the support plate 6 and perform sequential superposition of support stability, which is convenient for subsequent welding. Then the operator starts the electric push rod 91, and the electric push rod 91 drives the clamping block 92 to press against the column body 1, which is convenient for positioning the column body 1. Then rotate the double-headed lead screw 93 until the two positioning strips 95 clamp the cross beam body 2, which is convenient for maintaining the horizontal positioning welding of the cross beam body 2.
