Abstract
The utility model discloses a traction pipe with a special connecting structure, the convenient and fast connection of the traction pipe can be realized through welding a connecting pipe on the connecting end surface of the traction pipe, and then utilizing a connecting plate in the connecting pipe. With the utility model, the convenient, fast and firm connection between traction pipes can be realized, the reliability of the connection of traction pipes can be efficiently ensured, the production auxiliary time and cost can be reduced, and production efficiency and product quality of the product can be improved.
Description
Technical field
The utility model belongs to polyolefin pipe traction tube connection area, especially relates to a kind of traction tube of special syndeton.
Background technology
In the middle of the production process, as the skirt that polyolefin pipe is produced, it is long even surpass hundred meters that the length of traction tube often reaches tens of rice, and skirt is long more during particularly big more pipe production.Owing to the convenience of depositing and carrying, often skirt is cut into the segment length of 10-20 rice, in producing use, need the section of weak point skirt is connected to a satisfactory long tube.Traditional connected mode is on the end face cylindrical of traction tube, to punch; Utilize rope or iron wire to connect then; This connection belongs to the method that is flexible coupling, and there is following defective in this connected mode: one: connect built on the sand dislocation easily between the tube and tube; Can't guarantee to be connected axiality between the traction tube is blocked or damage equipment easily; Two: in distraction procedure, easy stretcher strain in the position that is flexible coupling even damage cause process of producing product to interrupt or influence product quality; Three: the connecting portion that is flexible coupling, because the cause of rope or iron wire causes the traction tube external diameter to increase, thereby increase the fault rate of distraction procedure, cause process of producing product to interrupt or influence product quality.
Summary of the invention
The technical problem that the utility model will solve provides a kind of easy to connect, quick, firm and can guarantee the syndeton of axiality between the traction tube, especially is fit to a kind of special construction connector that adopts and guarantees stability and the syndeton of axiality of traction tube between connecting.
The utility model is realized by following technical scheme; A kind of traction tube of special syndeton; Comprise the traction tube body, also be welded with the coupling assembling that two traction tubes are connected as one, also have operation window in the end sides of traction tube body in the termination at traction tube body two ends.
Said coupling assembling comprises the tube connector and the terminal pad that embeds in the tube connector of an end and the welding of traction tube body termination; The size of tube connector external diameter and traction tube external diameter is consistent; The tube connector inwall is divided into the internal diameter different portions; With the internal diameter of the tube connector part inner wall layer of traction tube body welding less than another part, excessive formation one step between two parts;
The external diameter of terminal pad is with suitable with the internal diameter of the tube connector part inner wall layer of traction tube body welding, and card ends said step place, and the terminal pad card is provided with at least three connecting holes that are used for wearing connecting screw rod.
The beneficial effect of the utility model is: through being provided with the link of connecting plate in the welding on traction tube; Utilize connecting plate to realize the connection of traction tube; Axiality between the traction tube has guaranteed to be connected; It is convenient, quick, firm to make also simultaneously that traction tube connects, and enhances productivity, and reduces production costs.
