Therefore, a pipe connection device is proposed to assist operators in pipe welding, making the operation more time-saving and labor-saving. Summary of the Invention

Then, the connection and fixation are achieved by passing through the fixing holes on the surfaces of the first fixing block and the second fixing block with bolts.

[0008] First, the first gun holder passes through the welding end of the welding gun and aligns the welding end with the pipe connection gap. Then, the first small electric push rod drives the first clamping block to clamp and fix the welding gun in position. Subsequently, the first slide rail cooperates with the first gun holder to slide in a semi-circular shape at the top between the first support ring and the second support ring to assist the personnel in passing through the welding end of the welding gun to carry out the welding work.

[0009] Subsequently, the welding gun is inserted through the welding end of the second gun holder, and the second clamping block is driven by the second small electric push rod to fix the welding gun in place. Then, the second slide rail cooperates with the second gun holder to slide in a semi-arc shape at the bottom between the first support ring and the second support ring to realize the welding work on the bottom periphery of the pipe. The operation is time-saving and labor-saving.

[0010] Specifically, one end of the first support ring and the second support ring are connected by rotational damping, and the top and bottom of the other end of the first support ring and the second support ring are respectively provided with a first fixing block and a second fixing block.

[0011] By adopting the above technical solution, rotational damping is used in conjunction with connecting clamps to fit around the pipe.

[0013] By adopting the above technical solution, the fixing holes on the surfaces of the first fixing block and the second fixing block are used to connect and fix the blocks with through bolts.

[0014] Specifically, the first gun mount and the second gun mount are slidably connected to the first slide rail and the second slide rail via sliders on both sides.

[0015] By adopting the above technical solution, the first slide rail and the second slide rail are used to cooperate with the first gun mount and the second gun mount respectively to perform a semi-circular sliding motion.

[0016] Specifically, a first clamping block is provided on the inner side of the first gun mount corresponding to the position of the first small electric push rod, and the driving end of the first small electric push rod is connected to the first clamping block.

[0017] By adopting the above technical solution, the first gun holder passes through the welding end of the welding gun and makes the welding end correspond to the pipe connection gap, and then the first clamping block is driven by the first small electric push rod to clamp and fix the welding gun.

[0018] Specifically, a second clamping block is provided on the inner side of the second gun mount corresponding to the position of the second small electric push rod, and the driving end of the second small electric push rod is connected to the second clamping block.

[0019] By adopting the above technical solution, the second gun holder passes through the welding end of the welding gun, and the second clamping block is driven by the second small electric push rod to fix the welding gun in place.

[0021] The present invention discloses a pipe connection device in which a first gun holder passes through the welding end of a welding gun and aligns the welding end with the pipe connection gap. Then, a first small electric push rod drives a first clamping block to clamp and fix the welding gun in place. Subsequently, a first slide rail cooperates with the first gun holder to slide in a semi-arc shape at the top between the first support ring and the second support ring to assist personnel in passing through the welding end of the welding gun to perform welding work.

[0022] The pipe connection device described in this utility model uses a second gun holder that passes through the welding end of the welding gun.

Then, the first small electric push rod 9 drives the first clamping block 10 to clamp and fix the welding gun. Subsequently, the first slide rail 6 cooperates with the first gun holder 8 to slide in a semi-arc shape at the top between the first support ring 101 and the second support ring 102 to assist the personnel in passing through the welding end of the welding gun to carry out the welding work.

[0034] Subsequently, the welding gun is inserted through the welding end of the welding gun by the second gun holder 11, and the second clamping block 13 is driven by the second small electric push rod 12 to fix the welding gun in place.

[0045] In use, the connecting clamp 1 is fitted around the pipe joint, and the first gun holder 8 and the second gun holder 11 correspond to the welding gap position. Then, the connection and fixation are achieved by passing through the fixing holes 5 on the surfaces of the first fixing block 3 and the second fixing block 4 with bolts.

[0046] First, the first gun holder 8 passes through the welding end of the welding gun and makes the welding end correspond to the pipe connection gap.
