Embodiment 1

[0030] The usage method of the device for installing the winch trough of the present invention will be explained in detail below through specific embodiments.

[0031] A method for using the device for installing the winch tank body of the present invention is specifically implemented according to the following steps:

[0032] Step 1, after the cylindrical tank body 7 to be installed is cut along the center line, after being fastened on the outer wall of the drum 6, the chain 2 is placed on the outer wall of the tank body 7 to be installed and the drum 6, and one end of the hydraulic cylinder 1 Butt on the outer wall of the drum 6, and the other end pushes up the chain 2.

[0033] Step 2, start the hydraulic station 3, the control box 5 is connected to the oil circuit, the hydraulic oil is pressed into the hydraulic cylinder 1 after passing through the oil pipeline 4, the rod end of the hydraulic cylinder 1 protrudes out and tightens the chain 2, and the tension of the chain 2...

Embodiment 2

[0036] A method for using the device for installing the winch tank body of the present invention is specifically implemented according to the following steps:

[0037] Step 1, after the cylindrical tank body 7 to be installed is cut along the center line, after being fastened on the outer wall of the drum 6, the chain 2 is placed on the outer wall of the tank body 7 to be installed and the drum 6, and one end of the hydraulic cylinder 1 Push up on the outer wall of the drum 6, and the other end lifts up the chain 2;

[0038] Step 2, start the hydraulic station 3, the control box 5 is connected to the oil circuit, the hydraulic oil is pressed into the hydraulic cylinder 1 after passing through the oil pipeline 4, the rod end of the hydraulic cylinder 1 protrudes out and tightens the chain 2, and the tension of the chain 2 makes the tank body 7 and the outer wall of the cylinder 6 are closely attached and compacted. The position limiting rod 8 limits the position of the groove ...

Abstract

The invention discloses a device for installing a winch groove body. The device comprises a roller and at least two hydraulic cylinders, wherein one ends of the two hydraulic cylinders abut against the outer side wall of the roller, the other end of each hydraulic cylinder is correspondingly provided with a lock chain wound around the outer side wall of the roller, the two hydraulic cylinders areeach connected with one end of an oil pipeline, the other end of the oil pipeline is connected with a hydraulic station, and an operation box is connected between the hydraulic cylinders and the hydraulic station in series. The invention also discloses a using method of the device. The using method comprises the steps that (1) the groove body to be installed is cut into two halves, and one half ofthe groove body abuts against the roller through the hydraulic cylinders; (2) hydraulic oil is controlled to be opened to jack up the hydraulic cylinders so that the half of the groove body to be installed is tightly attached to the roller, the correct axial and circumferential positions are ensured, and then plug welding is carried out; and (3) the extending ends of the hydraulic cylinders are retracted, and the other half of the groove body to be installed is continuously installed according to the steps of 1 and 2. According to the device and the method, the accurate installation and positioning of the groove body are ensured, the installation process is easy and labor-saving, and the safety performance is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a device for installing a winch trough, and also relates to a method for using the device. Background technique [0002] At present, the drawworks drum assembly of oil drilling rigs mostly adopts a split structure, that is, the cylindrical tank is cut along the center line, and then assembled by splicing, and the tank is fixed on the drum by plug welding or bolts. At present, there are no special tools for installing the tank body. The existing tank body installation method is: after the tank body cut along the center line is buckled on the roller, it is lifted by a crane or other lifting equipment, and the roller and tank body are used to lift it up. The self-weight makes the two snap together, and then the plug welding connection between the tank body and the drum is carried out, and finally the splicing and assembly of the entire tank body is realized....
