Description

Technical Field

[0001] The invention relates to the technical field of welding and cutting torches, in particular to an adjusting device for welding and cutting torches. Background Art

[0002] The main function of the welding and cutting torch is to mix the combustible gas and oxygen in the cutting torch to form a preheating flame with a certain heat energy and shape, and to eject a high-pressure oxygen flow from the center of the preheating flame to perform gas cutting. The fuel used is acetylene and oxygen.

[0003] Patent publication number CN103619524B discloses a welding torch adjustment device that can improve thermal countermeasures and easily set the welding torch angle. A welding torch adjustment device for adjusting the position of a welding torch composed of a welding torch or a cutting torch carried on a trolley (B) that is loaded with a workpiece and travels relative to the workpiece, comprises a welding torch bracket (27) for holding the welding torch in a detachable manner, a welding torch angle adjustment portion for adjusting the angle of the welding torch bracket relative to the workpiece, and a welding torch entry and exit adjustment portion for adjusting the entry and exit position by moving the welding torch bracket in a plane parallel to the workpiece in a direction orthogonal to the travel direction of the trolley (B). The welding torch bracket is formed into a groove shape consisting of a pair of upright pieces (27a, 27b) and a connecting piece (27c) connecting the pair of upright pieces. A mounting member (28) for mounting the welding torch in a detachable manner is provided on the connecting piece, and the welding torch is mounted on the welding torch angle adjustment portion via one of the upright pieces (27a).

[0004] However, this device still has some shortcomings: the device realizes welding and cutting of the workpiece through the angle adjustment part, but during the welding process, it is difficult to ensure that the bottom of the welding and cutting mechanism does not contact the top of the workpiece. Therefore, in the process of welding and cutting the workpiece, when the two come into contact with each other during welding and cutting, flame release and tempering are likely to occur, which easily increases the processing risk during the welding and cutting process. Summary of the Invention

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

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an adjustment device for a welding and cutting torch, comprising a base, a transmission mechanism is provided inside the base slide groove, an electric turntable is provided on the top of the transmission mechanism, a driving mechanism is fixedly installed on the top of the electric turntable, an oil and gas anti-oil device for removing oil stains from the equipment is provided below the driving mechanism, an anti-condensation device is provided on the periphery of the oil and gas anti-oil device to prevent acetylene and oxygen supply hoses from freezing at low temperatures, a bearing mechanism is slidably installed inside the driving mechanism, a mounting groove is provided at the bottom of the bearing mechanism, a welding and cutting mechanism is provided inside the bearing mechanism, two elastic retractable plates are symmetrically and fixedly installed at the left edge of the bottom of the bearing mechanism, a pulley is rotatably installed inside the retractable end of the elastic retractable plate, a heat collecting plate is hinged at the left edge of the driving mechanism by a torsion spring, a number of semicircular blocks are equidistantly and fixedly installed on the edge of one side of the heat collecting plate close to the bearing mechanism, and a convex ball rod is fixedly installed on the outer wall of the bearing mechanism.

[0007] According to the above technical solution, a slide groove is opened inside the base, and a moving mechanism is provided at the corners of the bottom of the base. The moving mechanism is used to convert the horizontal friction between the base and the ground into rolling friction, and the bottom of the electric turntable and the top of the transmission mechanism are rotatably connected.

[0008] According to the above technical solution, the carrying mechanism realizes vertical movement through the output end of the driving mechanism, and two connecting ends are provided at the right end of the top of the welding and cutting mechanism. The two connecting ends of the welding and cutting mechanism are respectively connected to the acetylene and oxygen supply ends through hoses, and the pulley converts the contact surface of the telescopic end of the elastic telescopic plate from sliding friction to rolling friction. The heat collecting plate realizes swing reset through a torsion spring, and the heat collecting plate covers the high temperature generated when the welding and cutting mechanism is working. The convex ball rod contacts the surface of the semicircular block away from the end of the carrying mechanism, and the base completes the azimuth adjustment through the rolling friction between the moving mechanism and the ground. When the workpiece needs to be welded and cut, the transmission mechanism is started, and the transmission mechanism drives the electric turntable to realize horizontal movement on the top of the base. At the same time, when the electric turntable starts and rotates on the top of the transmission mechanism, it will drive the driving mechanism to move synchronously, and the driving mechanism The structure causes the carrying mechanism to slide vertically inside itself, and the carrying mechanism drives the welding and cutting mechanism to approach the workpiece. At this time, the welding and cutting mechanism starts to weld and cut the workpiece through the acetylene and oxygen provided by the hose; when the carrying mechanism drives the elastic telescopic plate to move downward, the elastic telescopic plate drives the pulley to move synchronously. When the pulley moves vertically, it first contacts the top of the workpiece to be welded and cut. At the same time, the pulley is limited and suppressed by the elastic telescopic plate, so that its outer wall is always close to the top of the workpiece. When the carrying mechanism moves horizontally, the pulley starts to rotate due to the friction between it and the workpiece, and the pulley moves horizontally on the top of the workpiece in a rotating posture. At the same time, the carrying mechanism drives the convex ball rod to move vertically, and the convex ball rod is separated from the limit of the semicircular block. At this time, the heat collecting plate relies on the torsion spring to swing towards the carrying mechanism. When the convex ball rod hits the semicircular block again, the heat collecting plate is reset, and this cycle repeats.

[0009] According to the above technical solution, the oil and gas prevention device includes a negative pressure device, the top of which is fixedly installed inside the mounting groove of the supporting mechanism. The negative pressure device is used to extract the oil and gas diffused around the welding and cutting mechanism. The bottom of the negative pressure device is connected through a spiral hose and a vacuum gun is fixedly installed.

[0010] According to the above technical solution, the oil and gas prevention device also includes an L-shaped slide, the top end of the L-shaped slide passes through and is fixedly installed on the outer wall of the convex ball rod, a cross bar is installed inside the cross groove of the L-shaped slide through a spring sliding, the cross bar is fixedly installed on the outer wall of the vacuum gun near the side of the supporting mechanism, the cross bar passes through and is fixedly installed with a resistance roller near the outer wall of one end of the L-shaped slide, an arc panel is fixedly installed on the left side of the driving mechanism, and an oil isolation plate is fixedly installed on the resistance roller near the side of the supporting mechanism, the supporting mechanism drives the negative pressure device to move synchronously, and the negative pressure device transmits the suction force to the vacuum gun through the spiral hose. Before the welding and cutting mechanism is started, the vacuum gun absorbs the oil and gas diffused around the welding and cutting mechanism to avoid the volatilization of lubricating oil and other oils added during the equipment maintenance phase and thus distributing them around the welding and cutting mechanism.

[0011] The L-shaped plate is fixed to the left side of the driving mechanism, and the L-shaped plate is fixed to the left side of the driving mechanism, and the L-shaped plate is fixed to the right ... right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the L-shaped plate is fixed to the right side of the driving mechanism, and the

[0012] According to the above technical solution, the anti-condensation device includes two rotating rods, the bottoms of the two rotating rods are symmetrical and rotatably installed on the top of the electric turntable, the top of the rotating rods is fixedly installed with an impeller, the top of the driving mechanism is symmetrical and has two sliding plates installed through spring sliding, the top of the sliding plate is hinged with an inclined plate through a torsion spring, and the inclined plate is hinged with a top plate at one end away from the sliding plate.

[0013] When the cam is in the L-shaped groove, the cam is moved upwards to move the cam, and the cam is moved along the L-shaped groove so that the cam can move freely.

[0014] According to the above technical solution, a U-shaped frame is fixedly installed on the right side of the top of the sliding plate, and an insulation plate is fixedly installed on the outer wall of the U-shaped frame. The insulation plate is arc-shaped, and a heating mechanism is fixedly installed on the side of the U-shaped frame close to the top plate. The heating mechanism is used to prevent the fuel supply pipe of the welding mechanism from condensing under low temperatures outdoors. The sliding plate drives the U-shaped frame to move toward the direction close to the supporting mechanism, and the U-shaped frame drives the insulation plate and the heating mechanism to move synchronously. The heating mechanism approaches the fuel supply hose. When the low temperature environment causes the hose to harden, causing the fuel to condense inside it and thereby slowing down the circulation speed, the hose is softened by relying on the heat emitted by the reciprocating horizontal motion of the heating mechanism. At the same time, the insulation plate intercepts the heat emitted by the heating mechanism to increase the overall temperature within the activity range of the heating mechanism.

[0015] The present invention provides an adjustment device for a welding and cutting torch, which has the following beneficial effects: (1) The present invention cooperates with a transmission mechanism, an electric turntable, a driving mechanism, a bearing mechanism, a welding and cutting mechanism, an elastic telescopic plate, a pulley, a heat collecting plate, a semicircular block and a convex ball rod. The operation of the electric turntable and the driving mechanism realizes the orientation adjustment of the welding and cutting mechanism. At the same time, the transmission mechanism causes the welding and cutting mechanism to move horizontally and complete the welding and cutting of the workpiece, thereby improving the orientation adjustment capability and practicality of the welding and cutting mechanism. The pulley is used to prevent the welding and cutting mechanism from contacting the top of the workpiece, and a certain welding and cutting distance is maintained to prevent the occurrence of tempering and flame release. At the same time, the reciprocating heat collecting plate absorbs the heat generated by the welding and cutting mechanism during operation to prevent it from overflowing, thereby preventing the high temperature from radiating to external equipment and causing interference, thereby improving the protection of external equipment.

[0016] (2) The present invention adopts the setting of the oil and gas prevention device, and cooperates with the convex ball rod, the negative pressure device, the air extraction gun, the L-shaped slide plate, the cross bar, the contact roller, the arc plate and the oil isolation plate to extract the oil and gas around the welding and cutting mechanism through the negative pressure device and the air extraction gun, thereby avoiding the combustion phenomenon caused by the excessively high oil and gas content in the surrounding area when the welding and cutting mechanism is working, thereby improving the safety in the working area; the contact roller enables the air extraction gun to absorb the oil and gas around the welding and cutting mechanism at a closer distance, further shortening the removal rate of the dangerous components around the welding and cutting mechanism; at the same time, the oil isolation plate protects the bottom of the supporting mechanism, preventing the bottom of the supporting mechanism from being close to one end of the driving mechanism and other equipment, and being continuously exposed to oil and gas, thereby increasing the flammability.

[0017] (3) The present invention adopts the setting of the anti-condensation device, and cooperates with the L-shaped slide plate, rotating rod, impeller, sliding plate, inclined plate, top plate, U-shaped frame, insulation plate and heating mechanism. Through the reciprocating pushing of the top plate, the two ends of the hose are ensured to be tightly connected with the welding and cutting mechanism and the fuel supply end respectively, avoiding the phenomenon of loosening and leakage at one end, and facilitating the staff to check whether the hoses are in a non-entangled state, thereby realizing fast and safe inspection of the welding and cutting work; through the indirect heating of the heating mechanism, the cracking of the hose due to excessive heating caused by fixed-point heating is avoided, and the hose is softened by the heating mechanism, avoiding the hardened hose from breaking due to increased brittleness under the combing of the top plate, and at the same time avoiding the condensation of fuel inside the hose resulting in insufficient supply, thereby reducing the welding and cutting rate of the welding and cutting mechanism on the workpiece.

A carrying mechanism 6 is slidably installed inside the driving mechanism 5, and a mounting groove is provided at the bottom of the carrying mechanism 6. A welding and cutting mechanism 7 is provided inside the carrying mechanism 6. Two elastic telescopic plates 8 are symmetrically and fixedly installed at the left edge of the bottom of the carrying mechanism 6, and a pulley 9 is rotatably installed inside the telescopic end of the elastic telescopic plate 8. A heat collecting plate 10 is hinged at the left edge of the driving mechanism 5 through a torsion spring. A plurality of semicircular blocks 11 are equidistantly and fixedly installed on the edge of the heat collecting plate 10 near one side of the carrying mechanism 6, and a convex ball rod 12 is fixedly installed on the outer wall of the carrying mechanism 6.

[0022] A slide groove is provided inside the base 1, and a moving mechanism 2 is provided at the bottom corners of the base 1. The moving mechanism 2 is used to convert the horizontal friction between the base 1 and the ground into rolling friction. The bottom of the electric turntable 4 is rotatably connected to the top of the transmission mechanism 3.

[0023] The carrying mechanism 6 realizes vertical movement through the output end of the driving mechanism 5. Two connecting ends are provided at the top right end of the welding and cutting mechanism 7. The two connecting ends of the welding and cutting mechanism 7 are respectively connected to the acetylene and oxygen supply ends through hoses. The pulley 9 converts the contact surface of the telescopic end of the elastic telescopic plate 8 from sliding friction to rolling friction. The heat collecting plate 10 realizes swing reset through a torsion spring. The heat collecting plate 10 covers the high temperature generated when the welding and cutting mechanism 7 is working. The convex ball rod 12 is in contact with the surface of the semicircular block 11 at one end away from the carrying mechanism 6.

[0024] Through the operation of the electric turntable 4 and the driving mechanism 5, the orientation adjustment of the welding and cutting mechanism 7 is achieved. At the same time, the transmission mechanism 3 causes the welding and cutting mechanism 7 to move horizontally and complete the welding and cutting of the workpiece, thereby improving the orientation adjustment ability and practicality of the welding and cutting mechanism 7; the pulley 9 prevents the welding and cutting mechanism 7 from contacting the top of the workpiece, retains a certain welding and cutting distance to prevent tempering and flame release, and at the same time, the reciprocating heat collecting plate 10 absorbs the heat generated by the welding and cutting mechanism 7 during operation to prevent it from overflowing, prevents the high temperature from radiating to external equipment and causing interference, and improves the protection of external equipment.

[0025] When in use, the base 1 completes the orientation adjustment through the rolling friction between the moving mechanism 2 and the ground. When the workpiece needs to be welded and cut, the transmission mechanism 3 is started, and the transmission mechanism 3 drives the electric turntable 4 to realize horizontal movement on the top of the base 1. At the same time, when the electric turntable 4 is started and rotates on the top of the transmission mechanism 3, it will drive the driving mechanism 5 to move synchronously. The driving mechanism 5 prompts the supporting mechanism 6 to slide vertically inside itself, and the supporting mechanism 6 drives the welding and cutting mechanism 7 to approach the workpiece. At this time, the welding and cutting mechanism 7 starts to weld and cut the workpiece through the acetylene and oxygen provided by the hose; when the supporting mechanism 6 drives the elastic telescopic plate 8 to move downward, the elastic telescopic plate 8 drives the pulley 9 to move synchronously. When the pulley 9 moves vertically, it first contacts the top of the workpiece to be welded and cut. At the same time, the pulley 9 is limited and suppressed by the elastic telescopic plate 8, so that its outer wall is always close to the top of the workpiece. When the supporting mechanism 6 moves horizontally, the pulley 9 starts to rotate due to the friction between it and the workpiece, and the pulley 9 moves horizontally on the top of the workpiece in a rotating posture. At the same time, the supporting mechanism 6 drives the convex ball rod 12 to move vertically, and the convex ball rod 12 is separated from the limit of the semicircular block 11. At this time, the heat collecting plate 10 relies on the torsion spring to swing toward the direction close to the supporting mechanism 6. When the convex ball rod 12 again contacts the semicircular block 11, the heat collecting plate 10 is reset, and so on.

[0026] According to the above embodiment, the orientation adjustment of the welding and cutting mechanism 7 is achieved through the operation of the electric turntable 4 and the driving mechanism 5. At the same time, the transmission mechanism 3 prompts the welding and cutting mechanism 7 to move horizontally and complete the welding and cutting of the workpiece, thereby improving the orientation adjustment ability and practicality of the welding and cutting mechanism 7; the pulley 9 is used to prevent the welding and cutting mechanism 7 from contacting the top of the workpiece, and a certain welding and cutting distance is retained to prevent tempering and flame release. At the same time, the reciprocating heat collecting plate 10 absorbs the heat generated by the welding and cutting mechanism 7 during operation to prevent it from overflowing, prevents the high temperature from radiating to external equipment and causing interference, and improves the protection of external equipment.

[0027] See also Figures 1-8 , based on the above embodiment, another embodiment of the present invention further includes an oil and gas prevention device 13; The oil and gas prevention device 13 includes a negative pressure device 131. The top of the negative pressure device 131 is fixedly installed inside the mounting groove of the supporting mechanism 6. The negative pressure device 131 is used to extract the oil and gas diffused around the welding and cutting mechanism 7. The bottom of the negative pressure device 131 is connected through a spiral hose and is fixedly installed with an air extraction gun 132.

[0028] The oil and gas prevention device 13 also includes an L-shaped slide 133. The top of the L-shaped slide 133 passes through and is fixedly installed on the outer wall of the convex ball rod 12. A cross bar 134 is installed inside the cross groove of the L-shaped slide 133 through a spring sliding. The cross bar 134 is fixedly installed on the outer wall of the vacuum gun 132 near the side of the supporting mechanism 6. The cross bar 134 passes through the outer wall near one end of the L-shaped slide 133 and is fixedly installed with a resistance roller 135. An arc panel 136 is fixedly installed on the left side of the driving mechanism 5. An oil isolation plate 137 is fixedly installed on the side of the resistance roller 135 near the supporting mechanism 6.

[0029] The right end of the L-shaped slide 133 is slidably installed on the left edge of the driving mechanism 5. A transverse groove is provided on the side of the L-shaped slide 133 close to the supporting mechanism 6. The arc surface of the left end of the arc panel 136 is located on the movement trajectory of the outer wall of the resistance roller 135, and the top of the oil isolation plate 137 is in contact with the bottom of the supporting mechanism 6.

[0030] The negative pressure device 131 and the vacuum gun 132 are used to extract the oil and gas around the welding and cutting mechanism 7, thereby preventing the welding and cutting mechanism 7 from burning due to excessive oil and gas content in the surrounding area when the welding and cutting mechanism 7 is working, thereby improving the safety in the working area; the friction roller 135 is used to enable the vacuum gun 132 to absorb the oil and gas around the welding and cutting mechanism 7 at a closer distance, thereby further shortening the removal rate of dangerous components around the welding and cutting mechanism 7; at the same time, the oil isolation plate 137 protects the bottom of the supporting mechanism 6, preventing the bottom of the supporting mechanism 6 from being close to the end of the driving mechanism 5 and other equipment, and being continuously exposed to oil and gas, thereby increasing flammability.

[0031] When in use, the carrying mechanism 6 drives the negative pressure device 131 to move synchronously, and the negative pressure device 131 transmits the suction force to the air extraction gun 132 through the spiral hose. Before the welding and cutting mechanism 7 is started, the air extraction gun 132 absorbs the oil and gas diffused around the welding and cutting mechanism 7 to prevent the lubricating oil and other oils added during the equipment maintenance phase from evaporating and being distributed around the welding and cutting mechanism 7; the convex ball rod 12 drives the L-shaped slide plate 133 to move synchronously, the L-shaped slide plate 133 drives the cross bar 134 to move vertically, and the cross bar 134 drives the air extraction gun 132 to move downward, and When the cross bar 134 drives the resistance roller 135 to move downward, it contacts the arc surface of the outer wall of the arc panel 136. The resistance of the arc panel 136 causes the resistance roller 135 to generate a force to move in the direction of the welding and cutting mechanism 7. The resistance roller 135 causes the cross bar 134 to slide synchronously inside the L-shaped slide 133 and drives the vacuum gun 132 to move synchronously. Then the cross bar 134 is reset by the spring force, and this process repeats repeatedly, thereby shortening the distance between the vacuum gun 132 and the welding and cutting mechanism 7. At the same time, the resistance roller 135 drives the oil isolation plate 137 to move synchronously along the supporting mechanism 6.

[0032] According to the above embodiment, the negative pressure device 131 and the vacuum gun 132 are used to extract the oil and gas around the welding and cutting mechanism 7, so as to avoid combustion caused by excessive oil and gas content in the surrounding area when the welding and cutting mechanism 7 is working, thereby improving the safety in the working area; the friction roller 135 is used to enable the vacuum gun 132 to absorb the oil and gas around the welding and cutting mechanism 7 at a closer distance, thereby further shortening the removal rate of dangerous components around the welding and cutting mechanism 7. At the same time, the oil isolation plate 137 protects the bottom of the supporting mechanism 6 to prevent the bottom of the supporting mechanism 6 from being close to one end of the driving mechanism 5 and other equipment, and being continuously exposed to oil and gas, thereby increasing flammability.

[0033] See also Figures 1-8 , based on the above embodiment, another embodiment of the present invention further includes an anti-condensation device 14; The anti-condensation device 14 includes two rotating rods 141, the bottoms of the two rotating rods 141 are symmetrical and rotatably installed on the top of the electric turntable 4, the top of the rotating rods 141 is fixedly installed with an impeller 142, the top of the driving mechanism 5 is symmetrical and two sliding plates 143 are installed through spring sliding, the top of the sliding plate 143 is hinged with an inclined plate 144 through a torsion spring, and the inclined plate 144 is hinged with a top plate 145 at one end away from the sliding plate 143.

[0034] A non-self-locking reciprocating spiral groove is provided on the outer wall of the rotating rod 141. The outer wall of the spiral groove of the rotating rod 141 passes through and is movably installed inside the L-shaped slide 133. The sliding plate 143 is horizontally reset by the elastic force of a spring. The sliding plate 143 is located on the movement trajectory of the impeller 142 near one end of the rotating rod 141, and the top plate 145 pushes the fuel supply hose of the welding and cutting mechanism 7.

[0035] A U-shaped frame 146 is fixedly installed on the right side of the top of the sliding plate 143, and an insulation plate 147 is fixedly installed on the outer wall of the U-shaped frame 146. The insulation plate 147 is an arc-shaped design. A heating mechanism 148 is fixedly installed on the side of the U-shaped frame 146 close to the top plate 145. The heating mechanism 148 is used to prevent condensation in the fuel supply pipe of the welding and cutting mechanism 7 at low temperatures outdoors.

[0036] Through the reciprocating pushing of the top plate 145, it is ensured that the two ends of the hose are tightly connected to the welding and cutting mechanism 7 and the fuel supply end respectively, avoiding loosening and leakage at one end, and making it convenient for the staff to check whether the hoses are in a non-entangled state, thereby realizing fast and safe inspection of the welding and cutting work; through the indirect proximity heating of the heating mechanism 148, it is avoided that the hose will crack due to excessive temperature rise caused by fixed-point heating, and the heating mechanism 148 softens the hose, avoiding the hardened hose from increasing in brittleness and breaking under the combing of the top plate 145, and at the same time avoiding the condensation of fuel inside the hose resulting in insufficient supply, thereby reducing the welding and cutting rate of the welding and cutting mechanism 7 on the workpiece.

[0037] When in use, when the L-shaped slide plate 133 moves downward along the outer wall of the non-self-locking spiral groove of the rotating rod 141, the spiral groove limits the rotating rod 141, driving the rotating rod 141 to start rotating, and the rotating rod 141 drives the impeller 142 to revolve. When the impeller 142 revolves, it contacts and pushes the sliding plate 143 to slide along the top of the driving mechanism 5 toward the direction close to the supporting mechanism 6. When the impeller 142 passes over the sliding plate 143, the sliding plate 143 is reset by the elastic force of the spring. When the sliding plate 143 moves horizontally, it drives the inclined plate 144 to move synchronously. The inclined plate 144 is limited by the top plate 145, so that its own hinge axis starts to rotate. At this time, the inclined plate 144 drives the top plate 145 with the hinge axis as the axis. Move upward. Before the welding and cutting work begins, the top plate 145 pushes the hose that supplies acetylene and oxygen fuel to the welding and cutting mechanism 7; the sliding plate 143 drives the U-shaped frame 146 to move toward the direction of the supporting mechanism 6, and the U-shaped frame 146 drives the insulation plate 147 and the heating mechanism 148 to move synchronously. The heating mechanism 148 approaches the fuel supply hose. When the low temperature environment causes the hose to harden, causing the fuel to condense inside it and thus the circulation speed to slow down, the hose is softened by the heat emitted by the reciprocating horizontal motion of the heating mechanism 148. At the same time, the insulation plate 147 intercepts the heat emitted by the heating mechanism 148, thereby increasing the overall temperature within the activity range of the heating mechanism 148.

[0038] According to the above embodiment, the reciprocating pushing of the top plate 145 ensures that the two ends of the hose are tightly connected to the welding and cutting mechanism 7 and the fuel supply end respectively, avoiding loosening and leakage at one end, and making it convenient for the staff to check whether the hoses are in a non-entangled state, thereby realizing fast and safe inspection of the welding and cutting work; the indirect proximity heating by the heating mechanism 148 avoids the cracking of the hose due to excessive temperature rise caused by fixed-point heating, and the heating mechanism 148 softens the hose, avoiding the hardened hose from increasing its brittleness and breaking under the combing of the top plate 145, and at the same time avoiding the condensation of fuel inside the hose resulting in insufficient supply, thereby reducing the welding and cutting rate of the welding and cutting mechanism 7 on the workpiece.
