Continuous tube drawing device

Abstract

The invention discloses a continuous tube drawing device. The continuous tube drawing device comprises a rack (1), support bases (2) arranged on the rack (1), idler wheels (4), power systems (5) connected with the idler wheels (4) and support arms (3), wherein one end of each support arm (3) is connected with each support base (2) through a movable shaft, and the other end of each support arm (3) is connected with each idler wheel (4) through a movable shaft. The support bases (2), the support arms (3), the idler wheels (4) and the power systems (5) are all set to be two sets and are arranged symmetrically with the rack (1). The power systems (5) comprise transmission motors (51) and speed changers (52), wherein the output shafts of the transmission motors (51) are connected with the speed changers (52), and the idler wheels (4) are arranged on the output shafts of the speed changers (52). The continuous tube drawing device is stable in power output, a tube diameter is adjusted automatically, stress borne by tube materials is adjusted automatically, the tube materials and a transmission system can not be damaged by continuous tube drawing, and using is safer and more reliable.

Description

technical field [0001] The invention relates to a continuous pipe pulling machine, which is mainly used for continuous pulling of pipes in underground holes in construction projects and freezing projects. Background technique [0002] There are many types of pipe pulling machines, which are mainly used as supporting auxiliary equipment for drilling rigs in various geotechnical drilling and excavation projects. Pull out the drilling wall casing and drill pipe. It can also be used to pull out casing and drill pipe in various drilling tool accident treatment. This type of extubation machine is mainly a hydraulic extubation machine, which consists of four parts: a hydraulic station, an oil cylinder, a base, and a deck, and is connected with each other by a high-pressure hydraulic hose; the hydraulic station is composed of an overflow valve, a high-pressure reversing valve, an oil It is composed of road blocks; the card holder is the holding device of the tube extubation machin...

AI Technical Summary

Problems solved by technology

[0003] The equipment used for pulling out pipes in underground holes in construction projects or freezing projects is mainly for recycling PE plastic pipes. Because PE plastic pipes are soft in material and small in diameter, there is no need for a high-power pipe pulling machine, and the pulled out PE pipes can be recycled. Finally, it needs to be stored in coils, so this kind of extubation machine requires little power and can be continuously pulled out. The existing power system of this type of extubation machine is mostly belt and chain transmission, and there are the following problems: 1. Stability , Poor safety; 2. The size must be adjusted manually according to the diameter of the pipe to be pulled through the adjusting screw installed on the frame each time. The construction interval is long and the construction continuity is poor; 3. According to the pulling force, the bolts should be pre-adjusted Clamping force, easy to slip or pinch the pipe; 4. During pulling, the gap between the rollers is fixed, which is easy to damage the pipe. When the pipe is deformed or jointed, the pipe puller stays in this position, which damages the machine transmission system; 5. Since the connection between the support and the frame is adjustable in order to adjust the size, it is not convenient for transportation or manual handling

[0004] In the process of pulling out pipes in underground holes in existing construction projects or freezing projects, a stable and safe power output is required; it can be automatically adjusted according to the diameter of the pipe to be pulled out to ensure the continuity of construction; it can be adjusted according to the pipe resistance Size, automatic adjustment of frictional force, a tube extubator that solves the problems of easily damaged pipes and easily damaged transmission systems through joints, but there is no report in the prior art
