Description

Heat supply pipeline poling pulley

Technical Field

The utility model relates to a heat supply pipeline poling pulley belongs to municipal administration construction equipment technical field, concretely relates to pipeline installation equipment.

Background

In the municipal administration work progress, pipeline erection is very common, and most pipelines adopt direct landfill mode to go on, but receive the construction condition restriction during partial pipeline erection, and the construction adopts earlier pipe-jacking back poling operation, for example: and (4) installing a heat supply pipeline and a gas pipeline.

Common major diameter, long distance pipeline among the poling operation engineering generally adopt the socle to spread sand and trusteeship, and the progress is slow, causes unrecoverable damage to the heat preservation skin or the body of pipeline easily. Once the pipe body is damaged, the heat preservation effect is poor and energy is wasted, and in case of serious damage, the danger of gas leakage of the pipe body possibly exists, and the consequences are not reasonable.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art exists not enough, provides a poling pulley for assisting long distance, major diameter poling operation.

In order to solve the technical problem, the utility model discloses a technical scheme be: a heat supply line threading pulley comprising: the device comprises an outer ring, a roller and an inner clamp; the outer lane is the tubular structure, be fixed with the gyro wheel on the outer wall of outer lane, and a plurality of the central line of gyro wheel is perpendicular with the outer lane central line, be provided with the inside callipers in the intraductal interior card of outer lane, it is a plurality of the inside callipers are used for chucking heat supply pipeline.

The inside card includes: a movable frame and a clamping disc; be provided with curved inner wall on the chucking dish, it is a plurality of curved inner wall mutually supports and forms circularly, and is a plurality of curved inner wall conflict heat supply pipeline, chucking dish outer wall passes through the adjustable shelf and is connected with the outer lane, just the chucking dish can be close to or keep away from the outer lane inner wall through the adjustable shelf.

The adjustable shelf is a screw rod, the adjustable shelf penetrates through a threaded hole in the outer ring, and one end of the adjustable shelf is fixedly connected with the outer wall of the clamping disc.

And a hexagonal end head is fixed at the other end of the movable frame and used for clamping a wrench.

The roller comprises a roller frame and a roller; the two roller carriers are fixed on the outer wall of the outer ring, the roller is arranged between the two roller carriers, and the roller can rotate relative to the roller carriers.

The roller carrier is of a plate-shaped structure.

Compared with the prior art, the utility model beneficial effect who has is: the utility model adopts the pipe-penetrating pulley device, on one hand, the friction and the damage of the tunnel wall to the pipe body in the pipe-penetrating operation can be assisted, the operation efficiency is improved, and the whole quality of the pipe body is ensured; on the other hand, the pipe body has more diameters and types in the operation field, and the inner clamp is convenient to adapt to various pipelines, is beneficial to field use and is convenient to install.

Drawings

The present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.
