Detailed Implementation
[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] This utility model discloses a rapid rebar cage welding machine, such as... Figures 1-8 As shown, it includes a frame 1 and a guide frame 2. The guide frame 2 is located on one side of the outer surface of the frame 1. The frame 1 is mainly composed of two parallel longitudinal beams and multiple crossbeams that are alternately connected between the two longitudinal beams.
[0027] A fixed frame 4 is fixedly installed on one side of the top surface of the frame 1. A movable frame 3 is slidably connected to one side of the outer surface of the frame 1. The movable frame 3 can move along the frame 1. A support plate 5 is slidably connected inside the guide frame 2. The support plate 5 can move along the guide frame 2. A support frame 6 is fixedly installed on the top surface of the support plate 5. The movable frame 3 and the support frame 6 are fixedly connected. Since the support frame 6 and the support plate 5 are fixedly connected, when the movable frame 3 moves the support frame 6, it will move the support plate 5.
[0028] A vacuum cleaner 601 is fixedly installed on one side of the top surface of the support frame 6, and a filter box 603 is fixedly installed on one side of the top surface of the support frame 6. A connecting pipe 602 is fixedly connected between the inlet of the vacuum cleaner 601 and the filter box 603. The vacuum cleaner 601 drives the fan to rotate by a motor to generate airflow, and then the airflow sucks the smoke and dust generated when welding the steel cage into the filter box 603.
[0029] The outer surface of the filter box 603 is fixedly installed with a dust suction pipe 605 away from one end of the connecting pipe 602, and the dust suction pipe 605 is fixedly installed with a tee joint 606 away from one end of the filter box 603. The two ends of the tee joint 606 are fixedly installed with fixed pipes 607, and the ends away from the tee joint 606 of the two fixed pipes 607 are fixedly installed with dust suction heads 608. The tee joint 606 has three ports for merging the medium paths of the two fixed pipes 607. When the dust collector 601 operates, the external smoke dust enters the two dust suction heads 608 and then enters the two fixed pipes 607 through the two dust suction heads 608. The smoke dust entering the two fixed pipes 607 is merged into the dust suction pipe 605 through the tee joint 606, and finally enters the filter box 603 through the dust suction pipe 605.
[0030] The two dust suction heads 608 are located above and below, respectively, so as to be able to absorb the smoke dust above and below.
[0031] The inside of the filter box 603 is slidably connected with a plurality of filter plates 6031. When the smoke dust generated during welding enters the filter box 603 through the dust suction pipe 605, the smoke dust particles in the airflow are captured by the inertia impact on the surface of the filter plate 6031, thereby realizing the filtering effect of the larger size smoke dust particles.
[0032] The plurality of filter plates 6031 are arranged at equal intervals. The plurality of filter plates 6031 can filter the smoke dust multiple times. The filter plate 6031 can linearly slide inside the filter box 603. The outer surface of the filter box 603 is threadedly connected with a plurality of threaded rods 6032, and the plurality of threaded rods 6032 correspond to the plurality of filter plates 6031 one by one. One end of the threaded rod 6032 inside the filter box 603 is rotationally connected with the filter plate 6031, and the end away from the filter plate 6031 of the threaded rod 6032 is fixedly installed with a handle 6033.
[0033] The user holds and rotates the handle 6033 to drive the threaded rod 6032 to rotate. The rotating threaded rod 6032 moves under the action of the threads. When the threaded rod 6032 moves, it pushes the filter plate 6031 to move. The linearly sliding filter plate 6031 and the rotational connection between the threaded rod 6032 and the filter plate 6031 can prevent the filter plate 6031 from rotating with the rotation of the threaded rod 6032. The moving filter plate 6031 can move to the outside of the filter box 603 through the opening on one side of the outer surface of the filter box 603, so that the user can clean the filter plate 6031 used for a long time.
[0034] The top surface right side of the support plate 5 is fixedly installed with a treatment box 604, the outlet of the dust collector 601 is fixedly installed with a conveying pipe 609, and the conveying pipe 609 extends to the bottom of the treatment box 604. The filtered smoke dust enters the treatment box 604 through the conveying pipe 609, and the water in the treatment box 604 adheres to the residual smoke dust particles to increase the weight of the smoke dust particles, so that they fall to the bottom of the treatment box 604, thereby realizing the capture and settlement of the smoke dust particles.
[0035] The inner bottom surface of the treatment box 604 is fixedly installed with a guide block 6041, the outer surface left side upper portion of the treatment box 604 is fixedly installed with a water inlet pipe 6047, and the external water can enter the treatment box 604 through the water inlet pipe 6047. The outer surface right side upper portion of the treatment box 604 is fixedly installed with an air outlet pipe 6048, and the processed smoke dust is discharged through the air outlet pipe 6048.
[0036] The top surface right side of the support plate 5 is fixedly installed with a recovery box 6049, the outer surface right side lower portion of the treatment box 604 is fixedly installed with a water conveying pipe 6043 with a valve, and the water conveying pipe 6043 is fixedly connected with the recovery box 6049. The guide block 6041 is inclined and inclined towards the direction of the water conveying pipe 6043. When the valve of the water conveying pipe 6043 is opened, the water in the treatment box 604 flows into the water conveying pipe 6043 due to the inclined guide block 6041, and enters the recovery box 6049 through the water conveying pipe 6043 to settle, so as to separate the water and the smoke dust particles.
[0037] The outer surface left side middle portion of the recovery box 6049 is fixedly installed with an overflow pipe 6042 with a valve, and the overflow pipe 6042 is fixedly connected with the treatment box 604. When the water is separated and accumulated to the overflow pipe 6042, the valve of the overflow pipe 6042 is opened, so that the separated water reenters the treatment box 604 through the overflow pipe 6042, so as to recycle the water.
[0038] The end of the overflow pipe 6042 extending into the treatment box 604 is arc-shaped, so as to avoid that when the valve of the overflow pipe 6042 is opened, the water in the treatment box 604 enters the recovery box 6049 through the overflow pipe 6042.
[0039] The outer surface right side bottom of the recovery box 6049 is fixedly installed with a drain pipe 6044 with a valve. The valve of the drain pipe 6044 is opened, so as to discharge the separated smoke dust particles at the bottom of the recovery box 6049.
[0040] The inner top surface of the recycling box 6049 is slidably connected with a connecting rod 6046, one part of the connecting rod 6046 is located inside the recycling box 6049, and the other part is located on the outer surface of the recycling box 6049, one end of the connecting rod 6046 located inside the recycling box 6049 is fixedly installed with a floating ball 6045, and the floating ball 6045 and the connecting rod 6046 are both made of existing light materials, and the density is less than water. When the water in the treatment box 604 enters the recycling box 6049, the floating ball 6045 will float on the surface of the water in the recycling box 6049, and as the water level in the recycling box 6049 rises, the floating ball 6045 will rise, and the capacity of the water in the recycling box 6049 can be estimated by observing the part of the connecting rod 6046 extending outside the recycling box 6049, so that the staff can open the valve of the overflow pipe 6042 at the right time.
[0041] The bottom surface of the moving frame 3 is fixedly installed with a first motor 3011, and the output end of the first motor 3011 is fixedly installed with a second gear 3015. Both sides of the bottom surface of the moving frame 3 are rotatably connected with rotating rollers 3012, and both ends of the two rotating rollers 3012 are fixedly installed with movable wheels 3013. The movable wheels 3013 at both ends of the rotating rollers 3012 are in contact with the inner sides of the two sides of the rack 1. The outer surface of one side of the two rotating rollers 3012 is fixedly installed with a first gear 3014, and the second gear 3015 is engaged with the first gear 3014. The first motor 3011 drives the second gear 3015 to rotate, which drives the first gear 3014 engaged with the second gear 3015 to rotate. The rotation of the first gear 3014 drives one of the rotating rollers 3012 to rotate, which in turn drives the two movable wheels 3013 corresponding to the rotating roller 3012 to rotate, so that the moving frame 3 moves along the rack 1. When the moving frame 3 moves, the support frame 6 moves.
[0042] Because the main reinforcement is rotated and moved at the same time during welding of the reinforcement cage, the contact points between the stirrup and the main reinforcement increase in the direction of movement of the main reinforcement. The worker moves in the direction of the increasing contact points and welds the contact points. The moving frame 3 drives the support frame 6 to move, so that the dust collector 601 can timely absorb the welding dust, avoiding the reduction of dust collection effect due to the long distance between the dust collector 601 and the welding point.
[0043] The inside of the moving frame 3 is rotatably connected with a moving disc 301, and the inside of the fixed frame 4 is rotatably connected with a fixed disc 401. The moving disc 301 and the fixed disc 401 are both provided with a plurality of limiting holes on one side, so as to insert the reinforcing steel bars into the limiting holes.

[0045] The side of the moving disc 301 is fixedly provided with a plurality of installation pipes 3021 through bolts, the outer surface of the installation pipe 3021 is screw-connected with a fixing bolt 3022, one end of the reinforcing steel bar is inserted into the installation pipe 3021, then the fixing bolt 3022 is rotated to be in contact with the reinforcing steel bar inserted into the installation pipe 3021, until the reinforcing steel bar is pressed, so that the reinforcing steel bar is fixed in the installation pipe 3021.
[0046] The working principle of the utility model is as follows: a plurality of main reinforcement bars are sequentially inserted into the limiting holes of the fixing disc 401 and then inserted into the installation pipe 3021, then the fixing bolts 3022 on the outer surface of the plurality of installation pipes 3021 are sequentially rotated to be in contact with the main reinforcement bars inserted into the installation pipe 3021, until the main reinforcement bars are pressed, so that the main reinforcement bars are fixed in the installation pipe 3021, then the second motor 3023 drives the third gear 303 to rotate, so that the gear ring 302 engaged with the third gear 303 is rotated, so that the moving disc 301 is rotated, the rotation of the moving disc 301 drives the plurality of main reinforcement bars to rotate, at the same time, the first motor 3011 drives the second gear 3015 to rotate, so that the first gear 3014 engaged with the second gear 3015 is rotated, the rotation of the first gear 3014 drives one of the rotating rollers 3012 to rotate, so that the corresponding two movable wheels 3013 are rotated, so that the moving frame 3 is moved along the rack 1, when the moving frame 3 is moved, the support frame 6 is moved, so that the plurality of main reinforcement bars are moved and rotated at the same time, in the process, the hoop is wound on the outer surface of the plurality of main reinforcement bars by other equipment, in the winding process, the worker holds the welding gun to weld the place where the hoop is in contact with the main reinforcement bar;
[0047] During the welding process, the moving frame 3 drives the support frame 6 to move, the dust collector 601 rotates through the motor-driven fan to generate airflow, so that the smoke generated during welding can be sucked into the filter box 603 through the dust collection head 608, the fixed pipe 607 and the dust collection pipe 605, the smoke particles in the airflow are captured due to the inertia impact on the surface of the filter plate 6031, thereby realizing the filtering effect of the larger size smoke particles, the filtered smoke enters the treatment box 604 through the conveying pipe 609, and contacts with the water in the treatment box 604, and the water in the treatment box 604 is attached to the residual smoke particles to increase the weight of the smoke particles, so that they fall to the bottom of the treatment box 604, so as to realize the capture and settlement of the smoke particles, and the treated smoke is discharged through the air outlet pipe 6048.
