Abstract
The invention which is applicable for the field of pipe internal wall hot melting belt welding, provides a pipe internal wall hot melting belt welding supporting structure which comprises a plurality of arc-shaped top plates which lead the hot melting belt to be closely on the internal wall of the pipe, a plurality of telescopic force-applying devices which are connected with the arc-shaped top plates and push and pull the arc-shaped top plates, a fixed frame which is used for fixing the telescopic device, and a traveling trolley which can bear the fixed frame, the telescopic devices and the arc-shaped top plates. The supporting structure uses the traveling trolley for bearing the weight of the supporting structure and uses the telescopic devices for pushing and pulling the arc-shaped top plates; furthermore, the supporting structure has simple structure and convenient operation.
Description
Technical field
The invention belongs to pipe material inner wall hot melt belt and connect the field, relate in particular to a kind of structure for welding and supporting pipe material inner wall hot melt belt.
Background technology
Tubing is connected with various ways, but reaches certain value when the nominal bore diameter (Dn) of tubing, and as greater than 1200 millimeters the time, tubing connects the modes that adopt inner wall hot melt belts to connect more to be realized.How guaranteeing that hot melt band and pipe material inner wall fit tightly, is the major quality controlling point in connecting, and the bracing or strutting arrangement of choosing which kind of mode is particularly important.
The bracing frame scope of application commonly used at present is narrow, and support space is limited.Many mechanism's complicated operations, heavy being difficult for moves.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of structure for welding and supporting pipe material inner wall hot melt belt, is intended to solve existing supporting construction complicated operation, unreliable, the heavy problem that is difficult for moving of welding quality.
The embodiment of the invention is to realize like this, a kind of structure for welding and supporting pipe material inner wall hot melt belt, but comprise and make Electric thermal smelting belt fit tightly inner-walls of duct and execute some camber top boards of certain pre-applied force, be connected with the camber top board and the walking dolly of the several expansion device of push-and-pull camber top board, the fixed mount that supports retractor device and carrying fixed mount, retractor device and camber top board.
The present invention compared with prior art, beneficial effect is: but utilize the weight of walking dolly carrying supporting construction and adopt retractor device push-and-pull camber top board, simple in structure, be convenient to operation.
Description of drawings
Fig. 1 is the structure for welding and supporting pipe material inner wall hot melt belt schematic diagram that one embodiment of the invention provides.
Fig. 2 is the structure for welding and supporting pipe material inner wall hot melt belt schematic diagram that another embodiment of the present invention provides.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
But the weight of the structure for welding and supporting pipe material inner wall hot melt belt that the embodiment of the invention provides is by the walking dolly carrying, and employing retractor device push-and-pull camber top board, and is simple in structure, is convenient to operation.
As shown in Figure 1, but the structure for welding and supporting pipe material inner wall hot melt belt of one embodiment of the invention comprises some camber top boards 12, as some cylinder piston pairs 14, fixed mount 16 and the walking dolly 18 of retractor device.But described camber top board 12, cylinder piston secondary 14 and fixed mount 16 are by walking dolly 18 carryings.Fixed mount 16 is circle or polygon, and cylinder 14 is radially and is uniformly distributed on it.Camber top board 12 is installed on piston rod 142 tops of cylinder piston pair 14.After the cylinder ventilation, piston rod 142 is released camber top board 12 towards tubing 30 inwall directions, push the hot melt band 40 that overlays on tubing 30 inwalls until camber top board 12, and hot melt band 40 and tubing 30 inwalls are fitted tightly and convenient enforcement welding.After treating that hot melt band 40 is welded to tubing 30 inwalls, oppositely ventilation, piston rod 142 rollbacks are pulled back camber top board 12, and it is separated with hot melt band 40.Cylinder piston pair 14 in the present embodiment can use also that oil cylinder piston is secondary to be replaced, and can realize the release of camber top board 12 equally and pulls back.
As shown in Figure 2, but the structure for welding and supporting pipe material inner wall hot melt belt of another embodiment of the present invention comprises some camber top boards 22, the some feed screw nut pairs 24 as retractor device, bracing frame 26 and walking dolly 28.But described camber top board 22, feed screw nut pair 24 and bracing frame 26 are by walking dolly 28 carryings.Fixed mount 26 is circle or polygon, and screw mandrel 24 is radially and is uniformly distributed on it.Camber top board 22 is installed on screw mandrel one end of feed screw nut pair 24, and regulating feed screw nut pair 24 can the pushing tow or the camber top board 22 of pulling back.Rotary screw pair of nut 24 is released camber top board 22 towards tubing 30 inwall directions, push the hot melt band 40 that overlays on tubing 30 inwalls until camber top board 22, and hot melt band 40 and tubing 30 inwalls are fitted tightly and convenient enforcement welding.After treating that hot melt band 40 is welded to tubing 30 inwalls, return feed screw nut pair 24, camber top board 22 is pulled back, it is separated with hot melt band 40.Feed screw nut pair 24 quantity generally adopt the quantity of feed screw nut pair 24 to be no more than 12 by the shape and the radian decision of camber top board 22.Present embodiment also may be used on tubing and is oval situation, only needs fine setting screw mandrel 24, just can guarantee hot melt band 40 and pipe material inner wall are adjacent to.In addition, the supporting construction that present embodiment provides need not source of the gas and power supply, only need manually push away just and can advance in pipe, is convenient to operation in the hole.
But the weight of the structure for welding and supporting pipe material inner wall hot melt belt that the embodiment of the invention provides is carried by walking dolly, and adopts the secondary and feed screw nut pair push-and-pull camber top board of cylinder piston respectively, and is simple in structure, is convenient to operation.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
