Abstract
Claims
1. A pipe pull restorative device, characterized by, include: A connecting mechanism is used to install the drive mechanism and two sets of adjustable traction mechanisms; A drive mechanism, which pushes an adjacent adjustable traction mechanism and simultaneously pulls another set of adjustable traction mechanisms via a connecting mechanism; and Two sets of symmetrically arranged adjustable pulling mechanisms are provided. Each set of adjustable pulling mechanisms includes a guide frustum. An intermediate sleeve B is fixedly provided on the inner side of the guide frustum and is slidably sleeved on the outer side of the connecting rod and limited by an adjacent limiting pin. An adjusting plate is rotatably sleeved on the outer side of the intermediate sleeve B through a bearing. Multiple first locking grooves and second locking grooves are staggered on the outer side of the adjusting plate. The depth of the first locking groove is greater than the depth of the second locking groove. Adjusting handles are fixedly provided on both sides of the front of the adjusting plate. The adjustable pulling mechanism also includes multiple sets of blocking components evenly distributed on the outside of the adjusting plate. Each set of blocking components includes an extension plate that fits against the side of the guide frustum. A limiting sleeve that is fixedly connected to the guide frustum is slidably sleeved on the outside of the extension plate.
2. The pipe pull restorative device of claim 1, wherein: It also includes the old pipe to be repaired and two new pipes, the two new pipes being inserted into the inner sides of both ends of the old pipe to be repaired in a horizontal direction, and the inner diameter of the new pipes being larger than the diameter of the guide frustum.
3. The pipe pull restorative device of claim 2, wherein: The connecting mechanism includes a connecting rod, and limit holes are provided on both sides of the top of the connecting rod in a vertical direction.
4. The pipe pull restorative device of claim 3, wherein: Both of the limiting holes have a limiting pin that is slidably inserted into the inner side in the vertical direction, and the limiting pin is fixed to the inner side of the adjacent limiting hole by friction.
5. The pipe pull restorative device of claim 4, wherein: The drive mechanism includes an end plate. An intermediate sleeve A is fixedly disposed on the inner side of the end plate and is slidably sleeved on the outer side of the connecting rod and limited by an adjacent limiting pin. Two hydraulic cylinders are fixedly disposed on the left side of the end plate. The two hydraulic cylinders are connected to a hydraulic pump station that drives the output shaft of the hydraulic cylinders to extend and retract.
6. The pipe pull restorative device of claim 5, wherein: The output shafts of both hydraulic cylinders are fixedly connected to adjacent guide truncated cones, and the two hydraulic cylinders synchronously drive the adjacent guide truncated cones to move.
7. The pipe pull restorative device of claim 6, wherein: The adjustable pulling mechanism further includes a limiting groove formed on the surface of the limiting slide sleeve. A limiting slider fixedly connected to the extension plate is slidably arranged inside the limiting groove. A return spring is fixedly connected between the limiting slider and the inner wall of the limiting groove.
