Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

The utility model relates to a pipe drawing machine for an inner lining oil pipe 8, which is shown in figures 1 to 4, and the device of the utility model is designed to be capable of rapidly taking out the inner lining pipe in order to facilitate the extraction of the inner lining pipe in the oil pipe 8 after the clamping of the inner lining pipe in the oil pipe 8 and the oil pipe 8. Including oil pipe mount 1, set up mount foot 2 on the oil pipe mount 1, it places the district to be provided with inside lining oil pipe 8 in the oil pipe mount 1, still includes following subassembly: a motor 7 arranged at one end of the oil pipe fixing frame 1,

the supporting plate 5 is arranged in a placing area of the lining oil pipe 8, and the supporting plate 5 is used for fixing the lining oil pipe 8;

salvage lance 3, the afterbody is provided with rings 34, is connected with motor 7 through the steel cable, salvage lance 3 includes the lance, be provided with the chute on the lance, slips 31 is placed on the chute, be provided with swash plate 35 on the slips 31, still be provided with locking piece 32 on the chute, swash plate 35 wears to establish on locking piece 32, and is fixed mutually with locking piece 32.

The principle of the device is as follows: if the layer board 5 that 2 set up on oil pipe mount 1 sets up for bilateral symmetry, has formed the V-arrangement groove between two layer boards 5, establishes the oil pipe 8 body card and can realize the fixed of oil pipe 8 body between two layer boards 5, through the end of sticking the lining pipe with fishing spear 3, through motor 7 pulling steel cable, the steel cable is connected with the rings 34 of fishing spear 3 afterbody, fishing spear 3 pulls down, extracts the lining pipe.

Wherein, can refer to fig. 3 and fig. 4, the working principle of the fishing spear 3 is: be provided with the chute on fishing spear 3's spear, slips 31 fixes on the chute, and the swash plate 35 that sets up on slips 31 wears to establish on locking piece 32, therefore slips 31 can slide along the chute, and until slips 31 is higher than the surface of spear, at this moment, locking piece 32 can realize dying to the locking of swash plate 35, can block at the pipe wall of interior bushing pipe this moment and establish between slips 31 and spear, and the pulling through the steel cable drives fishing spear 3 and extracts interior bushing pipe, and the height of slips 31 in this device can be adjusted, adapts to taking out of the interior bushing pipe of different diameters.

Further, the motor 7 is placed on the motor bottom plate 6, and the motor bottom plate 6 is placed on the oil pipe fixing frame 1.
