Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding equipment, in particular to a synchronous double-changer for pipeline processing. Background Art

[0002] The pipeline processing process includes welding.

[0070] Specifically, welding parts are sleeved on both ends of the pipe to be welded, and then the pipes sleeved with the welding parts are respectively placed on the first mounting member 11 and the second mounting member 21 for fixing. Since the first transmission mechanism 12 is drivingly connected to the first mounting member 11, one end of the pipe is drivingly connected to the first transmission mechanism 12 based on the first mounting member 11; since the second transmission mechanism 22 is drivingly connected to the second mounting member 21, the other end of the pipe is drivingly connected to the second transmission mechanism 22 based on the second mounting member 21, so that both ends of the pipe rotate synchronously. Since both ends of the pipe rotate synchronously, the worker holds the electric welding instrument and realizes welding by means of the self-rotation of the pipe, improving the comfort of the worker's hand and the quality of pipe welding.

[0071] Further, the first transmission mechanism 12 includes a first driving wheel 121, a first driven wheel 122 and a first belt transmission mechanism 123; the first driving wheel 121 and the first driven wheel 122 are connected based on the first belt transmission mechanism 123; the first driven wheel 122 and the first mounting member 11 are coaxially arranged.

[0072] Specifically, the first mounting member 11 includes a first rotating disk 111 and a first fixing bracket 112. A second connecting shaft is provided between the first driven wheel 122 and the first rotating disk 111. One end of the second connecting shaft is connected to the first driven wheel 122, and the other end of the second connecting shaft passes through the first fixing bracket 112 and is connected to the first rotating disk 111, so that the first rotating disk 111 and the first driven wheel 122 rotate synchronously.

[0075] Specifically, the synchronous double-variable machine further includes a bracket 3. A first connecting shaft 31 is provided at the bottom of the bracket 3. The first connecting shaft 31 is located at the spacing between the second driving wheel 221 and the first driving wheel 121. One end of the first connecting shaft 31 is connected to the first driving wheel 121, and the other end of the first connecting shaft 31 is connected to the second driving wheel 221, so that the first driving wheel 121 and the second driving wheel 221 rotate synchronously based on the first connecting shaft 31. The second mounting member 21 includes a second rotating disk 211 and a second fixing bracket 212. A third connecting shaft is provided between the second driven wheel 222 and the second rotating disk 211. One end of the third connecting shaft is connected to the second driven wheel 222, and the other end of the third connecting shaft passes through the second fixing bracket 212 and is connected to the second rotating disk 211, so that the second rotating disk 211 and the second driven wheel 222 rotate synchronously.

[0076] Further, a motor 32 and a third belt transmission mechanism 33 are provided at the bottom of the bracket 3; a third driving wheel 34 is provided at the output end of the motor 32; a third driven wheel 35 is provided on the first connecting shaft 31; the third driving wheel 34 and the third driven wheel 35 are connected based on the third belt transmission mechanism 33; the motor 32 and the first connecting shaft 31 are drivingly connected based on the third driven wheel 35.

[0077] Specifically, the third driving wheel 34 on the output end of the motor 32 is connected to the third driven wheel 35 on the first connecting shaft 31 through the third belt transmission mechanism 33. The first connecting shaft 31 is connected to the output end of the motor 32 based on the third driven wheel 35, thereby driving the first connecting shaft 31 to rotate. Since one end of the first connecting shaft 31 is connected to the first driving wheel 121 and the other end of the first connecting shaft 31 is connected to the second driving wheel 221, the first driving wheel 121 and the second driving wheel 221 rotate following the first connecting shaft 31.

[0078] Further, the first fixing component 1 and the second fixing component 2 are located on the bracket 3.

[0079] Specifically, the first fixing component 1 and the second fixing component 2 are located on the bracket 3, which is convenient for workers to weld and reduces the number of times of bending down during welding.

[0080] Further, the synchronous double-variable machine further includes a support component 4; the support component 4 is located on the bracket 3.

[0081] Further, the support component 4 includes a lifting member 41, a screw 42, a handwheel 43, a guide rod 44, a worm 45 and a gear 46; one end of the lifting member 41 is fixedly connected to one end of the screw 42; the other end of the screw 42 extends to the bottom of the bracket 3; one end of the handwheel 43 is fixedly connected to one end of the worm 45; the gear 46 is threadedly connected to the screw 42, and the worm 45 is meshed with the gear 46; one end of the guide rod 44 is fixedly connected to the bracket 3, and the other end of the guide rod 44 is slidably connected to the lifting member 41.

[0082] Specifically, the lifting member 41 is used to support the pipeline, avoiding the pipeline from detaching from the fixation of the first mounting member 11 and the second mounting member 21 during the rotation process due to the heavy weight of the pipeline.

[0083] When the user needs to adjust the position of the lifting member 41 upward so that the lifting member 41 can better support the pipeline, the handwheel 43 is fixedly connected to one end of the worm 45. The user manually rotates the handwheel 43 in a certain direction to make the worm 45 rotate. Since the worm 45 is meshed with the gear 46, the gear 46 rotates. Since the gear 46 is threadedly connected to the screw 42, when the gear 46 rotates, the screw 42 moves upward; since one end of the lifting member 41 is fixedly connected to the screw 42, when the screw 42 moves upward, the lifting member 41 moves upward following the screw 42; one end of the guide rod 44 is fixedly connected to the bracket 3, and the other end of the guide rod 44 is slidably connected to the lifting member 41, enabling the lifting member 41 to move upward stably.

[0084] When the user needs to lower the position of the lifting member 41 so that the lifting member 41 can better support the pipeline, the user manually rotates the handwheel 43 in the opposite direction to make the worm 45 rotate. Since the worm 45 is meshed and connected with the gear 46, the gear 46 rotates. Since the gear 46 is threadedly connected to the screw 42, when the gear 46 rotates, the screw 42 moves downward, and the lifting member 41 follows the screw 42 and moves downward.

[0085] There is more than 1 support assembly 4, and all the support assemblies 4 are located on the bracket 3.

[0086] Further, the first mounting member 11 further includes a first sliding member 113. A first sliding groove 101 is provided on the first rotating disk 111, and the first sliding member 113 is slidably connected to the first sliding groove 101; there is more than 1 first sliding groove 101 and the first sliding member 113; one end of the first sliding member 113 is provided with a first fixing block 1131, and a first circular hole 102 is provided in the middle part of the first rotating disk 111; the first fixing block 1131 is located in the first circular hole 102 of the first rotating disk 111.

[0087] Specifically, when the welding part sleeved at one end of the pipeline is too large, the user moves the first sliding member 113 on the first rotating disk 111 away from the first circular hole 102 to make the first sliding member 113 slidably connected to the first sliding groove 101, and the welding part abuts against the first fixing block 1131, thereby fixing the welding part.

[0088] When the welding part sleeved at one end of the pipeline is too small, the user moves the first sliding member 113 on the first rotating disk 111 closer to the first circular hole 102 to make the first sliding member 113 slidably connected to the first sliding groove 101, and the welding part abuts against the first fixing block 1131, thereby fixing the welding part.

[0089] Further, the second mounting member 21 further includes a second sliding member 213. A third sliding groove 201 is provided on the second rotating disk 211, and the second sliding member 213 is slidably connected to the third sliding groove 201; there is more than 1 third sliding groove 201 and the second sliding member 213; one end of the second sliding member 213 is provided with a second fixing block 2131, and a second circular hole 202 is provided in the middle part of the second rotating disk 211; the second fixing block 2131 is located in the second circular hole 202 of the second rotating disk 211.

[0090] Specifically, when the welding part sleeved at the other end of the pipeline is too large, the user moves the second sliding member 213 on the second rotating disk 211 away from the second circular hole 202 to make the second sliding member 213 slidably connected to the third sliding groove 201, and the welding part abuts against the second fixing block 2131, thereby fixing the welding part.

[0091] When the welding piece sleeved on the other end of the pipeline is too small, the user moves the second sliding piece 213 on the second rotating disc 211 towards the direction close to the second round hole 202, so that the second sliding piece 213 is slidably connected with the third sliding groove 201, and the welding piece abuts against the second fixing block 2131, thereby fixing the welding piece.

[0092] Further, a slider 13 is provided at the bottom of the first fixing assembly 1, and a pull rod 14 is provided on one side of the first fixing assembly 1; a second sliding groove 301 is provided on the bracket 3; the slider 13 is slidably connected with the second sliding groove 301.

[0093] Specifically, when the pipeline is too short, the user pushes the pull rod 14 towards the direction close to the second fixing assembly 2, so that the slider 13 is slidably connected with the second sliding groove 301 towards the direction close to the second fixing assembly 2, thereby shortening the distance between the first fixing assembly 1 and the second fixing assembly 2; when the pipeline is too long, the user pulls the pull rod 14 away from the second fixing assembly 2, so that the slider 13 is slidably connected with the second sliding groove 301 away from the second fixing assembly 2, thereby increasing the distance between the first fixing assembly 1 and the second fixing assembly 2.

[0094] The utility model provides a synchronous double-variable machine for pipeline processing. Welding pieces are sleeved on both ends of the pipeline to be welded, and then the pipeline sleeved with the welding pieces is respectively placed on the first mounting member 11 and the second mounting member 21 for fixing. Since the first transmission mechanism 12 is drivingly connected with the first mounting member 11, one end of the pipeline is drivingly connected with the first transmission mechanism 12 based on the first mounting member 11; since the second transmission mechanism 22 is drivingly connected with the second mounting member 21, the other end of the pipeline is drivingly connected with the second transmission mechanism 22 based on the second mounting member 21, so that both ends of the pipeline rotate synchronously. Since both ends of the pipeline rotate synchronously, the worker holds the electric welding instrument and realizes welding by means of the self-rotation of the pipeline, improving the comfort of the worker's hand and the quality of pipeline welding.
