RIG Mast
Description
Product Name: RIG Mast
Overview
The mast is one of the important parts of the drilling rig and the workover rig, two-section telescoping mast, front-open, hydraulic cylinders for raising and telescoping, welded by high quality structure steel. It mainly consists of the following components: crown block, upper body, lower body, bearing mechanism, Y-type bracket, monkey board, escape device, raising cylinder, telescopic cylinder and its supporting device, standpipe assembly, guyline assembly and upper and lower body ladders and other components.
The standing up and putting down the mast is realized by the double-acting variable-level raising cylinder which mounted on the chassis and connected the lower body of the mast with the girder of the chassis. The sticking out and retracting of the mast is realized by two single-acting long telescopic cylinders, and a stabilizer mechanism is arranged in the middle of the telescopic cylinder to ensure the safety and stability of the mast when it is stretched out, retracted and worked.
Features
Designed and manufactured in accordance with API Spec 4F standards.
ANSYS finite element analysis technique is used to check the load distribution.
The material of the low temperature mast is low-alloy, high-strength, low-temperature impact-resistance material, and it is welded according to low temperature welding process, so it can meet the requirements of -45℃ low temperature environment.
Main standards for the design and manufacture of mast are as follows:
GB/T 23505: Petroleum Drilling and Workover Rigs
SY/T 5609: The types and basic parameters for oil drilling rigs
API Spec 4F: Specification for Drilling and Well Servicing Structures
SY/T 5170: Petroleum and natural gas industries-specification for wire rope
SY/T 5025: Specification for drilling and well servicing structures
API Spec 8A/8C: Specification for Drilling and Production Hoisting Equipment
Model
The commonly used product models of the mast are as follows: JJ15835 Mast, JJ18038 Mast, JJ22538 Mast
