[0003] The patent with the patent announcement number CN221363380U relates to the field of cable tray technology. The patent discloses a welding device for a special cable tray, which relates to the field of cable tray technology. The patent includes a welding table, a top seat is arranged above the welding table, a cable tray is arranged on the top of the welding table, a conveying assembly is arranged inside the welding table, and the conveying assembly includes a conveyor belt, a protrusion is fixedly connected to the outer surface of the conveyor belt, a conveying roller is connected to the inner wall of the conveyor belt, a rotating rod is fixedly connected at the center of the conveying roller, and a belt pulley 1 is fixedly connected to the outer surface of the rotating rod. The patent sets a conveying assembly, specifically, the starting motor drives the belt pulley 1 to rotate through the belt pulley 2, so that the rotating rod drives the conveying roller to rotate, and the conveyor belt conveys the cable tray.

[0004] In the above patent, a conveying assembly is provided, specifically, a starting motor drives pulley one to rotate through pulley two, thereby causing a rotating rod to drive a conveying roller to rotate, and the conveyor belt conveys the cable tray. However, during the conveying process, a too fast conveying speed may cause the cable tray to collide with each other, causing danger, damage to the cable tray, and possible injury to the staff. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a welding device for a cable tray, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a welding device for a cable tray includes a welding table, a table leg is fixedly installed at the bottom of the welding table, a welding frame is fixedly installed at the top of the welding table, a lifting device is fixedly installed at the top of the welding frame, the lifting device includes a lifting motor, a threaded rod and a sleeve, the lifting motor is fixedly installed on the top of the welding frame, the threaded rod is fixedly installed at the output end of the lifting motor, the sleeve is slidably installed on the circumferential surface of the threaded rod, the threaded rod is threadedly connected to the sleeve, a welding gun is fixedly installed on the circumferential surface of the sleeve, a slow conveying device is provided on the top of the welding table, a clamping device is provided on the welding table, and a collecting device is provided on the top of the welding table;

[0007] Wherein, the slow conveying device includes a transmission motor, a No. 1 transmission shaft, a friction disk, a No. 2 transmission shaft, a transmission belt, a conveyor belt and a No. 1 protrusion, the transmission motor is fixedly installed at the bottom of the welding table, the No. 1 transmission shaft is fixedly installed at the output end of the transmission motor, the friction disk is fixedly installed at the end of the No. 1 transmission shaft away from the transmission motor, the No. 2 transmission shaft is rotatably installed on the top of the welding table, the No. 1 transmission shaft is connected to the No. 2 transmission shaft through the transmission belt, the conveyor belt is fixedly installed on the circumferential surface of the No. 2 transmission shaft, the No. 1 protrusion is fixedly installed at the end of the conveyor belt away from the No. 2 transmission shaft, and the No. 1 protrusion is driven by the rotation of the conveyor belt to start moving, and the conveyor belt rotates to start conveying the cable bridge to the middle. The cable bridge does not need to be manually conveyed by the staff, which improves the work efficiency and increases the safety, so as to prevent the staff from manually conveying the cable bridge, which may cause unexpected dangers during the conveying period. The No. 1 protrusion arranged on the top of the conveyor belt increases the friction on the cable bridge during transportation, so as to prevent the smooth conveyor belt from having insufficient friction when conveying the cable bridge, resulting in slow transportation or transportation failure.

[0008] According to the above technical scheme, the slow conveying device also includes a deceleration column, a deceleration block and an elastic retractable plate. The deceleration column is fixedly mounted on one end of the No. 2 transmission shaft close to the transmission belt, the deceleration block is fixedly mounted inside the welding table, and the elastic retractable plate is fixedly mounted inside the deceleration column. The elastic retractable plate is driven by the deceleration column to start rotating. When the elastic retractable plate rotates, it contacts with the deceleration block. Under the squeezing of the deceleration block, the elastic retractable plate shrinks toward the inside of the deceleration column. Under continuous rotation, the elastic retractable plate keeps in contact with the deceleration block, and the elastic retractable plate keeps shrinking to achieve the purpose of deceleration, thereby slowing down the conveying speed of the conveyor belt to prevent the cable tray from colliding and being damaged due to excessive conveying speed of the conveyor belt.

[0009] The support frame is fixedly mounted on the top of the welding platform, and the welding block is slidably mounted on the bottom of the welding platform.

[0010] According to the above technical scheme, the clamping device also includes the No. 1 hydraulic cylinder, No. 1 hydraulic push plate, No. 1 hydraulic push rod, No. 2 hydraulic cylinder, No. 2 hydraulic push plate and No. 2 hydraulic push rod, the No. 1 hydraulic cylinder is fixedly installed on the left side of the push plate, the No. 1 hydraulic push plate is slidably installed on the inner wall of the No. 1 hydraulic cylinder, the No. 1 hydraulic push rod is fixedly installed on the end of the telescopic column close to the push plate, the No. 2 hydraulic cylinder is fixedly installed on the top of the bracket, the No. 2 hydraulic push plate is slidably installed on the inner wall of the No. 2 hydraulic cylinder, and the No. 2 hydraulic push rod is fixedly installed on the end of the No. 2 hydraulic push plate close to the welding frame, and the movement of the push block drives the L-shaped clamping rod to start moving. The movement of the L-shaped clamping rod releases the limit on the welding gun, so that the welding gun can start welding only after the push plate clamps the cable tray, which improves the safety of welding to prevent the staff from accidentally touching it before clamping, causing danger.

[0011] According to the above technical solution, the clamping device also includes a push block, a fixed plate and an L-shaped clamping rod. The push block is fixedly installed on the end of the No. 2 hydraulic push rod away from the No. 2 hydraulic push plate, and the fixed plate is fixedly installed on the top of the bracket. The L-shaped clamping rod slides through the fixed plate, and the movement of the push block drives the L-shaped clamping rod to start moving. The movement of the L-shaped clamping rod releases the limit on the welding gun, so that the welding gun can start welding only after the push plate clamps the cable tray, which improves the safety of welding and prevents danger caused by accidental touch by the staff before clamping.

[0012] According to the above technical solution, the No. 1 hydraulic cylinder is connected to the No. 2 hydraulic cylinder through a hydraulic pipe, the side of the L-shaped clamping rod in contact with the push block is set as an inclined surface, a No. 1 spring is provided between the push plate and the clamping plate, and a No. 2 spring is provided between the L-shaped clamping rod and the fixed plate. The movement of the push block drives the L-shaped clamping rod to start moving, and the movement of the L-shaped clamping rod releases the limitation on the welding gun, so that the welding gun can start welding only after the push plate clamps the cable tray, which improves the safety of welding and prevents danger caused by accidental touch by the staff before clamping.

[0013] According to the above technical scheme, the collecting device includes a fixed rod, a collecting box, a No. 3 rotating shaft, a rotating plate, a No. 2 protrusion and a knocking hammer.

When the plate starts to move, the fixed rod is driven to move, and the movement of the fixed rod drives the collecting box to move. When the collecting box moves to the bottom of the cable tray, it can catch the fallen welding slag during welding to make collection more convenient, so as to prevent the welding slag from falling on the welding table during welding and causing trouble in cleaning after welding.

[0014] According to the above technical solution, the collecting device also includes a bottom plate and a No. 3 protrusion, the bottom plate is fixedly installed inside the welding table, the No. 3 protrusion is fixedly installed on the top of the bottom plate, and a No. 3 spring is provided between the rotating plate and the collecting box. By sliding the No. 2 protrusion upward, the end of the rotating plate close to the striking hammer is continuously swung up and down, so that the striking hammer continuously strikes the cable tray when it is under the cable tray, so that the cable tray releases the internal stress before and after welding, so as to prevent the stress inside the cable tray from not being released before and after welding, resulting in fractures in the welding parts.

[0015] The present invention provides a welding device for a cable tray, which has the following beneficial effects:

[0016] (1) The invention drives the No. 1 protrusion to start moving by the rotation of the conveyor belt, and the conveyor belt starts to transport the cable tray to the middle. The staff does not need to manually transport the cable tray, which improves work efficiency and safety, and prevents the staff from manually transporting the cable tray, which may cause accidents and dangers during transportation. The No. 1 protrusion set on the top of the conveyor belt increases the friction on the cable tray during transportation, so as to prevent the smooth conveyor belt from having insufficient friction when transporting the cable tray, resulting in slow transportation or failure. The elastic retractable plate starts to rotate through the deceleration column. When the elastic retractable plate rotates, it contacts the deceleration block. Under the pressure of the deceleration block, the elastic retractable plate shrinks toward the inside of the deceleration column. Under continuous rotation, the elastic retractable plate keeps in contact with the deceleration block, and the elastic retractable plate keeps shrinking to achieve the purpose of deceleration, so as to slow down the conveying speed of the conveyor belt, so as to prevent the cable tray from colliding and being damaged due to excessive conveying speed of the conveyor belt.

[0017] (2) In the present invention, the movement of the telescopic column drives the clamping plate to start moving. After the clamping plate moves and contacts the cable tray, it continuously clamps the cable tray so that the cable tray will not move excessively or shake during the subsequent welding process, thereby preventing the cable tray from moving excessively or shaking during the welding process and causing welding failure. The movement of the push block drives the L-shaped clamping rod to start moving. The movement of the L-shaped clamping rod releases the limit on the welding gun, so that the welding gun can start welding only after the push plate clamps the cable tray, thereby improving the safety of welding and preventing danger caused by accidental touch by the staff before clamping.

[0018] (3) The invention drives the fixing rod to move when the plate starts to move, and the movement of the fixing rod drives the collecting box to move. When the collecting box moves to the bottom of the cable tray, it can catch the fallen welding slag during welding, making collection more convenient, so as to prevent the welding slag from falling on the welding table during welding and causing trouble in cleaning after welding. The second protrusion slides upward to make the rotating plate close to the hammer to swing up and down continuously, so that the hammer continuously strikes the cable tray when it is under the cable tray, so that the cable tray releases the internal stress before and after welding, so as to prevent the stress inside the cable tray from not being released before and after welding, resulting in fractures in the welding parts.

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.

The No. 1 projection 207 is driven to move by the rotation of the conveyor belt 206. The conveyor belt 206 rotates and starts to transport the cable tray to the middle, eliminating the need for workers to manually transport the cable tray, which improves work efficiency and increases safety, to prevent workers from manually transporting the cable tray, which may cause unexpected dangers during transportation. The No. 1 projection 207 set on the top of the conveyor belt 206 increases the friction on the cable tray during transportation, to prevent slow transportation or transportation failure due to insufficient friction of the smooth conveyor belt when transporting the cable tray.

[0032] The slow-down conveying device also includes a deceleration column 208, a deceleration block 209 and an elastic retractable plate 210. The deceleration column 208 is fixedly mounted on one end of the No. 2 transmission shaft 204 close to the transmission belt 205, the deceleration block 209 is fixedly mounted inside the welding table 1, and the elastic retractable plate 210 is fixedly mounted inside the deceleration column 208. The elastic retractable plate 210 is driven by the deceleration column 208 to start rotating. When the elastic retractable plate 210 rotates, it contacts with the deceleration block 209. Under the squeezing of the deceleration block 209, the elastic retractable plate 210 contracts toward the deceleration column 208. Under continuous rotation, the elastic retractable plate 210 is in continuous contact with the deceleration block 209, and the elastic retractable plate 210 continuously contracts to achieve the purpose of deceleration, thereby slowing down the conveying speed of the conveyor belt 206 to prevent the conveying speed of the conveyor belt 206 from being too fast, causing the cable tray to collide and be damaged.

The No. 1 protrusion 207 set on the top of the conveyor belt 206 Block 207 increases the friction force on the cable tray during transportation to prevent slow transportation or transportation failure due to insufficient friction of the smooth conveyor belt when transporting the cable tray; when the No. 2 transmission shaft 204 starts to rotate, it drives the deceleration column 208 to start rotating, and the deceleration column 208 drives the elastic retractable plate 210 to start rotating. When the elastic retractable plate 210 rotates, it contacts with the deceleration block 209. Under the squeezing of the deceleration block 209, the elastic retractable plate 210 shrinks toward the inside of the deceleration column 208. Under continuous rotation, the elastic retractable plate 210 continues to contact with the deceleration block 209, and the elastic retractable plate 210 continues to shrink to achieve the purpose of deceleration, so as to slow down the conveying speed of the conveyor belt 206 to prevent the conveying speed of the conveyor belt 206 from being too fast, causing the cable tray to collide and be damaged.

When the collecting box 402 moves to the bottom of the cable tray, it can catch the fallen welding slag during welding, making collection more convenient, so as to prevent the welding slag from falling on the welding table 1 during welding, and the trouble of cleaning after welding is prevented; the collection box 402 moves to drive the third rotating shaft 403 to move, and the third rotating shaft 403 moves to drive the rotating plate 404 to move, and the rotating plate 404 moves to drive the second protrusion 405 to move, and the second protrusion 405 moves to contact the third protrusion 408 on the top of the bottom plate 407 so that the second protrusion 405 slides upward continuously, and the second protrusion 405 slides upward to make the rotating plate 404 close to the end of the knocking hammer 406 constantly swing up and down, so that the knocking hammer 406 constantly knocks the cable tray under the cable tray so that the cable tray releases the internal stress before and after welding, so as to prevent the stress inside the cable tray from being released before and after welding, resulting in fracture of the welding part.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
