Description

Technical Field

[0001] This utility model relates to the field of plastic-coated composite pipe processing technology, specifically to a plastic-coated composite pipe processing and welding equipment. Background Technology

[0002] Plastic-coated composite pipes use welded steel pipes / seamless steel pipes as the base material, and form a steel-plastic composite structure by melting a plastic anti-corrosion layer on the inner and outer walls through hot-dip plastic coating or spraying processes. Typical coating materials include polyethylene (PE), epoxy resin (EP), polypropylene (PP), etc.

[0003] Currently, welding equipment is used in the processing of plastic-coated composite pipes to weld two butt-jointed plastic-coated composite pipes. However, the existing plastic-coated composite pipe processing and welding equipment has a simple overall structure. After fixing the two butt-jointed plastic-coated composite pipes, it cannot drive them to rotate, which is inconvenient for personnel to weld them. Therefore, a plastic-coated composite pipe processing and welding equipment is proposed. The pipe pressing assembly presses the two plastic-coated composite pipes into an arc-shaped groove. The geared motor drives the shaft and the transmission wheel on its outer side to rotate, which drives the plastic-coated composite pipe in the arc-shaped groove to rotate, making it easier for personnel to weld them. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a plastic-coated composite pipe processing and welding equipment. The pipe pressing assembly presses two plastic-coated composite pipes into an arc-shaped groove. The geared motor drives the shaft and the transmission wheel on its outer side to rotate, causing the plastic-coated composite pipes in the arc-shaped groove to rotate, which facilitates welding by personnel.

[0005] The technical solution adopted by this utility model to solve its technical problem is a plastic-coated composite pipe processing and welding equipment, including a base plate, a clamping assembly provided on the top of the base plate, the clamping assembly including a plate sleeve fixed to the top of the base plate by bolts, a connecting plate sleeved on the top of the plate sleeve, a clamping sleeve welded to the top of one side of the connecting plate, and a first base and a second base welded to both ends of the base plate respectively.

[0006] The first base and the second base have arc grooves on their tops. The first base and the second base are rotatably connected to a shaft through bearings. A transmission wheel is fixedly sleeved on the outside of the shaft through a flat key. A reduction motor is fixed to one end of the first base and the second base through bolts.

[0007] By adopting the above technical solution, the geared motor drives the shaft and the transmission wheel on its outer side to rotate, which in turn drives the plastic-coated composite pipe placed in the arc groove to rotate. The height of the welding gun fixed in the sleeve can be adjusted by moving the connecting plate up and down.

[0008] Specifically, the top of the transmission wheel is located inside the arc-shaped groove, the outer side of the transmission wheel is fitted with an anti-slip sleeve, and the output shaft on one side of the reduction motor is fixedly connected to one end of the shaft through a connecting sleeve.

[0009] Specifically, one side of the plate sleeve is connected to a fixing bolt via a threaded groove, and one side of the connecting plate is provided with equidistant locking holes corresponding to the fixing bolts.

[0010] Specifically, the first base and the second base are both provided with a pressure tube assembly on the top of the outer side of the arc groove. The pressure tube assembly includes a gantry frame that is fixed to the top of the first base and the second base by bolts. The top of the gantry frame is welded with an internal threaded sleeve, and a long screw is sleeved through the internal threaded sleeve.

[0011] Specifically, the bottom end of the long screw located inside the gantry is connected to a structural frame via a bearing, and a pressure roller is rotatably connected inside the structural frame via a bearing.

[0012] Specifically, a rocker arm is fixed to the top of the long screw by bolts, and auxiliary rods are connected to both ends of the top of the structural frame by threaded grooves, with the auxiliary rods penetrating the gantry frame.

[0013] The beneficial effects of this utility model are:

[0014] (1) The plastic-coated composite pipe processing and welding equipment of this utility model has a deceleration motor driving shaft and multiple transmission wheels on its outer side to rotate. The rotation of the transmission wheels pushes the plastic-coated composite pipe pressed by the rocker arm to rotate, which facilitates the comprehensive welding of its connection.

[0015] (2) In the plastic-coated composite pipe processing and welding equipment described in this utility model, when the connecting plate is moved up and down, the welding gun head fixed in the sleeve contacts the connection of the two plastic-coated composite pipes. Hold the rocker arm and rotate the long screw, and push the structural frame and the pressing roller down through the internal thread sleeve to press the plastic-coated composite pipe in the arc groove.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The pipe pressing assembly presses two plastic-coated composite pipes into an arc-shaped groove. A geared motor drives the shaft and its outer transmission wheel to rotate, causing the plastic-coated composite pipes within the arc-shaped groove to rotate, facilitating welding. Figure 1-4 As shown, the plastic-coated composite pipe processing and welding equipment of this utility model includes a base plate 1, a fastening assembly 4 is provided on the top of the base plate 1, the fastening assembly 4 includes a plate sleeve 401 fixed to the top of the base plate 1 by bolts, a connecting plate 402 is sleeved on the top of the plate sleeve 401, a clamping sleeve 403 is welded to the top of one side of the connecting plate 402, and a first base 2 and a second base 3 are welded to both ends of the base plate 1 respectively.

[0024] The first base 2 and the second base 3 have an arc-shaped groove 6 on their tops. The first base 2 and the second base 3 are both rotatably connected to a shaft 7 through a bearing. The shaft 7 is fixedly fitted with a transmission wheel 8 through a flat key on its outer side. The first base 2 and the second base 3 are both fixed with a reduction motor 10 by bolts at one end.

[0025] In use, the geared motor 10 drives the shaft 7 and the transmission wheel 8 on its outer side to rotate, pushing the plastic-coated composite pipe placed in the arc groove 6 to rotate. The vertical movement of the connecting plate 402 can adjust the height of the welding gun fixed in the sleeve 403.

[0026] For example, such as Figure 3 As shown, the present invention also includes the following: the top end of the transmission wheel 8 is located inside the arc groove 6; an anti-slip sleeve 9 is sleeved on the outside of the transmission wheel 8; and the output shaft on one side of the reduction motor 10 is fixedly connected to one end of the shaft rod 7 through a connecting sleeve.

[0027] In use, the geared motor 10 drives the shaft 7 to rotate, and the anti-slip sleeve 9 can increase the friction between the transmission wheel 8 and the plastic-coated composite pipe.

[0028] For example, such as Figure 2As shown, the present invention also includes a fixing bolt 404 connected to one side of the plate sleeve 401 through a threaded groove, and a locking hole 405 corresponding to the fixing bolt 404 is provided at equal intervals on one side of the connecting plate 402.

[0029] When in use, tighten the fixing bolt 404 so that one end is inserted into the corresponding clip hole 405 to fix the connecting plate 402 that moves up and down.

[0030] For example, such as Figure 4 As shown, the present invention also includes a pressure tube assembly 5 on the top of the first base 2 and the second base 3 located outside the arc groove 6. The pressure tube assembly 5 includes a gantry frame 501 fixed to the top of the first base 2 and the second base 3 by bolts. The top of the gantry frame 501 is welded with an internal threaded sleeve 502, and a long screw 503 is sleeved through the internal threaded sleeve 502.

[0031] During use, the long screw 503 rotates and moves downward through the internal threaded sleeve 502.

[0032] For example, such as Figure 4 As shown, the present invention also includes a structural frame 504 connected to the bottom end of the long screw 503 inside the gantry frame 501 via a bearing, and a pressure roller 505 is rotatably connected inside the structural frame 504 via a bearing.

[0033] In use, the long screw 503 moves down and presses the plastic-coated composite pipe through the pressing roller 505 in the structural frame 504, and the pressing roller 505 can limit the plastic-coated composite pipe.

[0034] For example, such as Figure 4 As shown, the present invention also includes a rocker arm 506 fixed to the top of the long screw 503 by bolts, and auxiliary rods 507 connected to the top two ends of the structural frame 504 by threaded grooves, the auxiliary rods 507 penetrating the gantry frame 501.

[0035] When in use, the rocker arm 506 is designed to make it easy for personnel to hold and rotate the long screw 503, and the auxiliary rod 507 is designed to prevent the structural frame 504 from rotating along with the long screw 503 without affecting its up and down movement.

[0036] When using this utility model, the operator connects the device to an external power source using a power cord, places the welding machine next to the base plate 1, inserts the welding torch into the sleeve 403, and secures it with bolts.

[0037] Place the two plastic-coated composite pipes to be joined in the arc-shaped groove 6 at the top of the base plate 1 and the first base 2, and make the ends of the two plastic-coated composite pipes stick together. Hold the rocker arm 506 and rotate the long screw 503. Through the inner thread sleeve 502, push the structural frame 504 and the pressing roller 505 down to press the plastic-coated composite pipe in the arc-shaped groove 6.

[0038] When the connecting plate 402 moves up and down, the welding gun head fixed in the sleeve 403 contacts the connection of the two plastic-coated composite pipes. Tighten the fixing bolt 404 so that one end is inserted into the corresponding clip hole 405, and fix the connecting plate 402 and the welding gun after moving up and down. The electric welding machine works to weld the plastic-coated composite pipes through the welding gun.

[0039] Turn on the geared motor 10 to drive the shaft 7 and the multiple transmission wheels 8 on its outer side to rotate. The rotation of the transmission wheels 8 pushes the plastic-coated composite pipe pressed by the rocker arm 506 to rotate, which facilitates the comprehensive welding of its connection. The anti-slip sleeve 9 is set to prevent slipping, so that the rotation of the transmission wheel 8 can drive the plastic-coated composite pipe to rotate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
