[0003] The patent with the patent announcement number CN217224017U relates to a suspended long-arm welding machine, belonging to the technical field of suspended welding machines. It includes a suspended welding machine main body and a support mechanism; the support mechanism includes a base, a pulley is installed on the lower surface of the base, a fixed arm is vertically fixed in the center on the upper surface of the base, a telescopic arm is movably inserted through the top of the fixed arm, and an installation component for installing the suspended welding machine main body is arranged at the top of the telescopic arm; the installation component includes a connecting plate one horizontally fixed at the top of the telescopic arm, a rotating seat is rotatably installed at the top of the connecting plate one, a connecting ear plate is movably inserted on the rotating seat, a fixing pin passing through the connecting ear plate horizontally penetrates through the side wall of the rotating seat, and a connecting plate two is fixed on the connecting ear plate. This suspended long-arm welding machine can support the suspended long-arm welding machine and has functions of multi-angle adjustment and height adjustment.

[0004] In the above patent, it has the function of conveniently adjusting the height of the suspended long-arm welding machine. By movably inserting a telescopic arm through the top of the fixed arm, the operator can quickly adjust the height of the welding machine main body under standardized operation. Quickly adjusting the height of the welding machine main body can enable the operator to more efficiently adapt to the needs of different workpieces during the welding process. However, after the adjustment is completed, the operator needs to spend time on limiting the telescopic arm to ensure that the telescopic arm will not get out of control. When the operator makes a mistake and does not perform the limiting work in a timely manner, the un-limited telescopic arm will move or extend, resulting in harm to the operator and surrounding personnel. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a suspended long-arm welding machine, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: a suspended long-arm electric welding machine, including a moving platform, on the top of which a housing is fixedly installed. Inside the housing, a support plate is fixedly installed. A hole is opened at the bottom of the moving platform, and a limiting groove is opened on the surface of the housing. An arc surface one is opened on the top of the support plate. Among them, the adjusting device includes a lifting mechanism, a welding mechanism, a control gear, a hand crank, a circular sleeve, a Z-shaped plate, a limiting plate and an L-shaped sliding plate. Push the hand crank to rotate in a specified direction. The rotation of the hand crank drives the control gear to rotate in a specified direction. The lifting mechanism is fixedly installed on the top of the support plate. A gear one is fixedly installed on the circumferential surface of the lifting mechanism close to the support plate. The welding mechanism is fixedly installed on the top of the free end of the lifting mechanism. The control gear is rotatably installed on the inner wall of the housing. The control gear meshes with the gear one. The hand crank rotates through the inner and outer walls of the housing. One end of the hand crank close to the housing is fixedly installed on the surface of the control gear away from the lifting mechanism. The circular sleeve slidably penetrates the circumferential surface of the hand crank. The Z-shaped plate is fixedly installed on the circumferential surface of the circular sleeve close to the control gear. The limiting plate is fixedly installed at one end of the Z-shaped plate away from the circular sleeve. The movement of the circular sleeve drives the Z-shaped plate to move away from the control gear. The movement of the Z-shaped plate drives the limiting plate to move away from the control gear. The L-shaped sliding plate slidably penetrates the inner and outer walls of the hand crank. The limiting plate contacts the inner wall of the limiting groove. During the movement, the limiting plate separates from the limiting groove, so that the limit applied by the housing to the hand crank is released.

[0007] According to the above technical solution, a first spring is arranged between the circular sleeve and the hand crank. When the circular sleeve moves, it compresses the first spring. The restored first spring drives the circular sleeve to move to the initial position. A rectangular groove is opened on the circumferential surface of the circular sleeve. During the reset process, the L-shaped sliding plate contacts the rectangular groove. An arc surface two is opened on the surface of the circular sleeve close to the control gear.

[0008] According to the above technical solution, the L-shaped sliding plate contacts the inner wall of the rectangular groove. Push the L-shaped sliding plate to move upward. During the movement, the surface where the L-shaped sliding plate contacts the rectangular groove separates, so that the limit applied by the L-shaped sliding plate to the circular sleeve is released. A first inclined surface is opened at one end of the L-shaped sliding plate close to the circular sleeve. During the movement, the arc surface two of the circular sleeve contacts the first inclined surface of the L-shaped sliding plate, so that the reset of the circular sleeve drives the L-shaped sliding plate to move upward. A second spring is arranged between the L-shaped sliding plate and the hand crank. When the L-shaped sliding plate moves, it compresses the second spring. The restored second spring drives the L-shaped sliding plate to move to the initial position.

[0009] According to the above technical solution, the protection device includes a buffer damper, a U-shaped plate, a contact plate, a rubber sheet, a round rod and a linkage plate. When the lifting mechanism moves downward to a predetermined position, it contacts the top of the U-shaped plate, causing the lifting mechanism to drive the U-shaped plate to move downward. The buffer damper is fixedly installed on the top of the moving platform, the U-shaped plate is fixedly installed on the top of the free end of the buffer damper, the contact plate slidably penetrates the inner and outer walls of the U-shaped plate, the rubber sheet is fixedly installed at one end of the contact plate close to the housing, the round rod is fixedly installed on the surface of the contact plate. When the U-shaped plate moves, it drives the contact plate to move downward, the movement of the contact plate drives the rubber sheet to move downward, and at the same time, the movement of the contact plate drives the round rod to move downward. The linkage plate slidably penetrates the inner and outer walls of the U-shaped plate.

[0010] According to the above technical solution, an arc surface three is provided on the surface of the contact plate close to the support plate. A spring three is arranged between the contact plate and the U-shaped plate. The restored spring three drives the contact plate to reset, and the reset of the contact plate drives the rubber sheet to reset. A corrugation one is provided on the surface of the rubber sheet close to the housing. The corrugation one of the rubber sheet contacts the inner wall of the housing during movement, causing friction to be generated between the rubber sheet and the housing when the rubber sheet continues to move.

[0011] According to the above technical solution, an arc surface four is provided on the surface of the linkage plate close to the support plate. The arc surface four of the linkage plate contacts the arc surface one of the support plate during movement, causing the linkage plate to be subjected to a resistance force applied by the support plate and move towards the housing when it continues to move. A groove is provided on the surface of the linkage plate close to the round rod. The groove contacts the circumferential surface of the round rod. The movement of the groove of the linkage plate drives the round rod to move towards the housing. A spring four is arranged between the linkage plate and the U-shaped plate.

[0012] According to the above technical solution, the stabilizing device includes an adapter box, a long plate, a carrying plate, a cushion plate, a bending piece and a clamping plate. When the U-shaped plate moves downward, it contacts the top of the long plate, causing the U-shaped plate to drive the long plate to move downward, and the long plate drives the carrying plate to move downward. The adapter box is fixedly installed on the inner wall of the housing, the long plate is slidably installed on the inner wall of the adapter box, the carrying plate is slidably installed on the surface of the long plate, the cushion plate is fixedly installed at the bottom of the carrying plate, the bending piece is fixedly installed at the bottom of the long plate, the end of the bending piece away from the long plate is fixedly installed at the bottom of the inner wall of the carrying plate, the clamping plate slidably penetrates the inner and outer walls of the long plate. A spring five is arranged between the long plate and the adapter box. A card slot is provided on the surface of the carrying plate. The carrying plate contacts the inner wall of the hole. The bending piece itself has elasticity. When the bending piece is squeezed, it deforms, and the deformed bending piece exerts a downward reaction force on the carrying plate under the action of its own elasticity.

[0013] According to the above technical solution, a second corrugation is provided at the bottom of the backing plate. The second corrugation of the backing plate contacts the ground during the movement, and the backing plate stops moving downward. An arc surface four is provided on the surface of the clamping plate close to the carrying plate, and the arc surface four contacts the inner wall of the carrying plate. A sixth spring is arranged between the clamping plate and the long plate. The arc surface four of the clamping plate separates from the inner wall of the carrying plate during the movement, so that the compressed sixth spring is restored to drive the clamping plate to move away from the long plate.

[0014] The present invention provides a suspended long-arm electric welding machine, which has the following beneficial effects:

[0015] (1) In this suspended long-arm electric welding machine, when the limiting plate moves, it separates from the limiting groove, so that the limitation exerted by the outer shell on the hand crank is released. By limiting the hand crank, it is realized that after the operator operates in a standard manner, the limitation on the hand crank can be quickly released, ensuring that the height of the electric welding mechanism can only be adjusted after correct operation. The Z-shaped plate resets to drive the limiting plate to reset. The limiting plate contacts the limiting groove during the reset process, and automatically limits the hand crank after adjusting the position of the electric welding mechanism, effectively reducing the workload of the operator and thus improving work efficiency.

[0016] (2) In this suspended long-arm electric welding machine, when the first corrugation moves, it contacts the inner wall of the outer shell, so that a frictional force is generated between the rubber sheet and the outer shell. By intermittently contacting the inner wall of the outer shell with the rubber sheet, an intermittent frictional force is applied to the U-shaped plate, and the downward movement speed of the U-shaped plate is slowed down by the intermittent frictional force, thereby improving the buffering effect. The groove of the linkage plate moves to drive the round rod to move towards the outer shell, and the movement of the round rod drives the contact plate to move. By changing the contact mode between the rubber sheet and the outer shell when the linkage plate contacts the support plate, the rubber sheet is always attached to the inner wall of the outer shell, thereby enhancing the protection effect when dealing with emergencies.

[0017] (3) In this suspended long-arm electric welding machine, the bent sheet in deformation exerts a downward reaction force on the carrying plate. Under the influence of the reaction force, the backing plate is in close contact with the ground, and the supporting force exerted by the ground is obtained through the close contact between the backing plate and the ground, avoiding the harm caused to the operator by the offset of the moving platform in case of emergencies, thereby improving the safety during work. When the clamping plate moves through the card slot during movement, the long plate is limited by the carrying plate. By limiting the long plate, it is ensured that the long plate can stably transmit the supporting force exerted by the ground to the moving platform, effectively improving the stability in the face of emergencies.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-4, an embodiment of the present invention is: a suspended long-arm electric welding machine, including a mobile platform 1, a housing 2 is fixedly installed on the top of the mobile platform 1, a support plate 3 is fixedly installed on the inner wall of the housing 2, a hole is opened at the bottom of the mobile platform 1, a limiting groove is opened on the surface of the housing 2, a first arc surface is opened on the top of the support plate 3, and an adjusting device is further included; wherein, the adjusting device includes a lifting mechanism 4, an electric welding mechanism 5, a control gear 6, a hand crank 7, a circular sleeve 8, a Z-shaped plate 9, a limiting plate 10 and an L-shaped sliding plate 11. The lifting mechanism 4 is fixedly installed on the top of the support plate 3, a first gear is fixedly installed on the circumferential surface of the lifting mechanism 4 close to the support plate 3, the electric welding mechanism 5 is fixedly installed on the top of the free end of the lifting mechanism 4, the control gear 6 is rotatably installed on the inner wall of the housing 2, the control gear 6 meshes with the first gear, the hand crank 7 rotatably penetrates the inner and outer walls of the housing 2, and one end of the hand crank 7 close to the housing 2 is fixedly installed on the surface of the control gear 6 away from the lifting mechanism 4. The circular sleeve 8 slidably penetrates the circumferential surface of the hand crank 7, the Z-shaped plate 9 is fixedly installed on the circumferential surface of the circular sleeve 8 close to the control gear 6, the limiting plate 10 is fixedly installed at one end of the Z-shaped plate 9 away from the circular sleeve 8, the L-shaped sliding plate 11 slidably penetrates the inner and outer walls of the hand crank 7, and the limiting plate 10 contacts the inner wall of the limiting groove. By limiting the rotation of the hand crank 7, it is ensured that the operator can only adjust the height of the electric welding mechanism 5 after standard operation, effectively improving the accuracy during operation.

[0029] A first spring is arranged between the circular sleeve 8 and the hand crank 7. A rectangular groove is opened on the circumferential surface of the circular sleeve 8, and a second arc surface is opened on the surface of the circular sleeve 8 close to the control gear 6. By arranging the first spring between the circular sleeve 8 and the hand crank 7, it is ensured that the circular sleeve 8 can automatically return to the initial position after moving, preparing for the next work.

[0030] The L-shaped sliding plate 11 contacts the inner wall of the rectangular groove. A first inclined surface is opened at one end of the L-shaped sliding plate 11 close to the circular sleeve 8. A second spring is arranged between the L-shaped sliding plate 11 and the hand crank 7. After adjusting the position of the electric welding mechanism 5, the hand crank 7 is automatically limited, reducing the work burden of the operator and thus improving the work efficiency.

[0031] During the operation of this embodiment, when lowering the height of the electric welding mechanism 5, the L-shaped sliding plate 11 is pushed upward. When the L-shaped sliding plate 11 moves, it compresses the second spring. At the same time, the surface of the L-shaped sliding plate 11 in contact with the rectangular groove during the movement is separated, so that the limit applied by the L-shaped sliding plate 11 to the circular sleeve 8 is released, and the circular sleeve 8 is pushed to move away from the control gear 6. When the circular sleeve 8 moves, it compresses the first spring. At the same time, the movement of the circular sleeve 8 drives the Z-shaped plate 9 to move away from the control gear 6. The movement of the Z-shaped plate 9 drives the limiting plate 10 to move away from the control gear 6. The limiting plate 10 is separated from the limiting groove during the movement, so that the limit applied by the housing 2 to the hand crank 7 is released. By limiting the rotation of the hand crank 7, it is ensured that the height of the electric welding mechanism 5 can only be adjusted under standard operation. Push the hand crank 7 to rotate in the specified direction. The rotation of the hand crank 7 drives the control gear 6 to rotate in the specified direction. When the control gear 6 rotates, it drives the first gear to rotate. The rotation of the first gear drives the lifting mechanism 4 to move downward. The movement of the lifting mechanism 4 drives the electric welding mechanism 5 to move downward. After the electric welding mechanism 5 moves to the specified position, release the L-shaped sliding plate 11, so that the compressed second spring restores and drives the L-shaped sliding plate 11 to move to the initial position. Release the circular sleeve 8, so that the compressed first spring restores and drives the circular sleeve 8 to move to the initial position. The movement of the circular sleeve 8 drives the Z-shaped plate 9 to reset. The reset of the Z-shaped plate 9 drives the limiting plate 10 to reset. The limiting plate 10 contacts the limiting groove during the reset process. At the same time, the second arc surface of the circular sleeve 8 contacts the first inclined surface of the L-shaped sliding plate 11 during the movement, so that the reset of the circular sleeve 8 drives the L-shaped sliding plate 11 to move upward. The L-shaped sliding plate 11 compresses the second spring when it moves. When the circular sleeve 8 resets to the initial position, the compressed second spring restores and drives the L-shaped sliding plate 11 to reset. The L-shaped sliding plate 11 contacts the rectangular groove during the reset process. By automatically limiting the hand crank 7 after adjusting the position of the electric welding mechanism 5, the work burden of the operator is effectively reduced, thereby improving work efficiency.

[0032] Please refer to Figures 1-8 Based on the above embodiment, in another embodiment of the present invention, a protection device and a stabilizing device are further included; the protection device includes a buffer damper 121, a U-shaped plate 122, a contact plate 123, a rubber sheet 124, a round rod 125 and a linkage plate 126. The buffer damper 121 is fixedly installed on the top of the moving platform 1. The U-shaped plate 122 is fixedly installed on the free end top of the buffer damper 121. The contact plate 123 slides through the inner and outer walls of the U-shaped plate 122. The rubber sheet 124 is fixedly installed at one end of the contact plate 123 close to the housing 2. The round rod 125 is fixedly installed on the surface of the contact plate 123. The linkage plate 126 slides through the inner and outer walls of the U-shaped plate 122. The buffer damper 121 performs a buffering operation after the lifting mechanism 4 moves to the specified position, ensuring the safety of the operator when adjusting the electric welding mechanism 5, thereby improving the safety of the operation.

[0033] The surface of the contact plate 123 close to the support plate 3 is provided with a third arc surface. A third spring is arranged between the contact plate 123 and the U-shaped plate 122. The surface of the rubber sheet 124 close to the housing 2 is provided with a first corrugation. By intermittently contacting the inner wall of the housing 2 through the rubber sheet 124, an intermittent frictional force is applied to the U-shaped plate 122, so that the downward movement speed of the U-shaped plate 122 is slowed down under the influence of the interval frictional force, thereby improving the buffering effect of the buffer damper 121.

[0034] The surface of the linkage plate 126 close to the support plate 3 is provided with a fourth arc surface. The surface of the linkage plate 126 close to the round rod 125 is provided with a groove, and the groove is in contact with the circumferential surface of the round rod 125. A fourth spring is arranged between the linkage plate 126 and the U-shaped plate 122. By changing the contact mode between the rubber sheet 124 and the housing 2 after the linkage plate 126 contacts the support plate 3, the rubber sheet 124 is always in contact with the housing 2 after intermittent contact, which helps to improve the protection effect when dealing with emergencies.

[0035] The stabilizing device includes an adapter box 131, a long plate 132, a carrier plate 133, a backing plate 134, a bending piece 135 and a clamping plate 136. The adapter box 131 is fixedly installed on the inner wall of the housing 2. The long plate 132 is slidably installed on the inner wall of the adapter box 131. The carrier plate 133 is slidably installed on the surface of the long plate 132. The backing plate 134 is fixedly installed at the bottom of the carrier plate 133. The bending piece 135 is fixedly installed at the bottom of the long plate 132. One end of the bending piece 135 away from the long plate 132 is fixedly installed at the bottom of the inner wall of the carrier plate 133. The clamping plate 136 slidably penetrates the inner and outer walls of the long plate 132. A fifth spring is arranged between the long plate 132 and the adapter box 131. The surface of the carrier plate 133 is provided with a card slot, and the carrier plate 133 is in contact with the inner wall of the hole. The bending piece 135 itself has elasticity. By closely contacting the ground through the backing plate 134, the supporting force exerted by the ground is obtained, so as to avoid the moving platform 1 shifting and causing harm to the operator in case of emergencies.

[0036] The bottom of the backing plate 134 is provided with a second corrugation. The surface of the clamping plate 136 close to the carrier plate 133 is provided with a fourth arc surface, and the fourth arc surface is in contact with the inner wall of the carrier plate 133. A sixth spring is arranged between the clamping plate 136 and the long plate 132. By being limited after the long plate 132 moves to a predetermined position, it is ensured that the long plate 132 will not shake after the movement is completed, so as to realize the stable transmission of the supporting force exerted by the ground to the moving platform 1 by the long plate, effectively improving the stability in the face of emergencies.

[0037] When the present embodiment is working, when the lifting mechanism 4 moves downward to a predetermined position and contacts the top of the U-shaped plate 122, the downward movement of the lifting mechanism 4 drives the U-shaped plate 122 to move downward. The movement of the U-shaped plate 122 drives the free end of the buffer damper 121 to move downward. At the same time, the movement of the U-shaped plate 122 drives the contact plate 123 to move downward. The movement of the contact plate 123 drives the rubber sheet 124 to move downward. At the same time, the movement of the contact plate 123 drives the round rod 125 to move downward. The arc surface three of the contact plate 123 contacts the arc surface one of the support plate 3. The contact plate 123 continues to move and moves in the direction of the housing 2 under the resistance applied by the support plate 3. When the contact plate 123 moves, it compresses the spring three. At the same time, the movement of the contact plate 123 drives the rubber sheet 124 to move in the direction of the housing 2. The first corrugation of the rubber sheet 124 contacts the inner wall of the housing 2 during movement, so that the rubber sheet 124 continues to move and generates a frictional force with the housing 2. The downward movement speed of the U-shaped plate 122 is slowed down by the frictional force. When the contact plate 123 separates from the support plate 3, the compressed spring three restores and drives the contact plate 123 to reset. The reset of the contact plate 123 drives the rubber sheet 124 to reset. The surface where the first corrugation contacts the housing 2 during reset separates. By intermittently contacting the inner wall of the housing 2 through the rubber sheet 124 to apply intermittent frictional force to the U-shaped plate 122, it helps to improve the buffering effect of the buffer damper 121. The downward movement of the U-shaped plate 122 drives the linkage plate 126 to move downward. When the U-shaped plate 122 moves to the lowest position, it stops moving. At the same time, the arc surface four of the linkage plate 126 contacts the arc surface one of the support plate 3 during movement, so that the linkage plate 126 continues to move and moves in the direction of the housing 2 under the resistance applied by the support plate 3. When the linkage plate 126 moves, it compresses the spring four. At the same time, the groove of the linkage plate 126 moves and drives the round rod 125 to move in the direction of the housing 2. The movement of the round rod 125 drives the contact plate 123 to move in the direction of the housing 2. The movement of the contact plate 123 drives the rubber sheet 124 to move in the direction of the housing 2. The rubber sheet 124 contacts the inner wall of the housing 2 during movement. After the linkage plate 126 moves to a predetermined position, it stops moving, so that the compressed spring four cannot be restored. By making the rubber sheet 124 always fit with the inner wall of the housing 2 when the linkage plate 126 contacts the support plate 3, it helps to improve the protection effect when dealing with emergencies;

[0038] When the U-shaped plate 122 moves downward, it contacts the top of the long plate 132, causing the U-shaped plate 122 to drive the long plate 132 to move downward. When the long plate 132 moves, it compresses the fifth spring. At the same time, the long plate 132 drives the carrier plate 133 to move downward, and the carrier plate 133 drives the cushion plate 134 to move downward. The second corrugation of the cushion plate 134 contacts the ground during the movement, and the cushion plate 134 stops moving downward, causing the long plate 132 to continue moving and compress the bending piece 135. The bending piece 135 deforms under the extrusion. The deformed bending piece 135 exerts a downward reaction force on the carrier plate 133 under the action of its own elasticity. The carrier plate 133 transmits the reaction force to the cushion plate 134. Under the influence of the reaction force, the cushion plate 134 is in close contact with the ground. By being in close contact with the ground, the cushion plate 134 obtains the supporting force exerted by the ground, avoiding the offset of the moving platform 1 in case of emergencies. While the long plate 132 moves downward, it drives the clamping plate 136 to move downward. The fourth arc surface of the clamping plate 136 separates from the inner wall of the carrier plate 133 during the movement, causing the compressed sixth spring to recover and drive the clamping plate 136 to move away from the long plate 132. When the clamping plate 136 moves, it passes through the card slot, causing the long plate 132 to be limited by the carrier plate 133. After being limited, the long plate 132 cannot move. By being limited after the long plate 132 moves to a predetermined position, it is ensured that the long plate 132 can stably transmit the supporting force exerted by the ground to the moving platform 1, effectively improving the stability in the face of emergencies.
