Description

A vehicle-mounted long-stroke belt press working machine

technical field

The present invention relates to an oilfield workover equipment, in particular to a vehicle-mounted long-stroke snubbing machine. the

Background technique

With the introduction and promotion of snubbing technology, domestic snubbing equipment has been developed and promoted to a certain extent. However, looking at the domestic pressurized operation equipment, it can be roughly divided into two categories, one is independent, and the other is auxiliary, but they all rely on floating slips and fixed slips to pour out the pipe string, and their up and down strokes Most of them are 3.3m, and one pipe string needs to be poured out of the wellhead repeatedly for 3-4 times. The disadvantages are complex operation, low operating efficiency and poor reliability. the

Contents of the invention

In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a vehicle-mounted long-stroke working machine with pressure. , Simplify the mode of operation in order to maximize operating efficiency and reduce energy consumption. the

The technical solution adopted in the present invention is: a vehicle-mounted long-stroke pressurized working machine, including a car chassis, a rotating platform is arranged at the rear of the car chassis, and a hydraulic power system, an energy storage system, and an operating system of the working machine are installed on the car chassis. , a derrick oil cylinder is installed on the rotating platform, and a hoisting system and a pressurization system are installed on the derrick oil cylinder. The hoisting system is composed of a piston rod on the upper part of the derrick oil cylinder connected to a hoisting crane, a fixed hoisting wheel at the middle and upper part, and a hoisting wire rope passing through the rotating slips , hoisting crown block and lifting fixed wheel, the end of which is connected to the tension gauge mechanism, the pressurization system is composed of the lower piston rod of the derrick oil cylinder connected to the pressurized crown block, the middle and lower part is fixed to pressurize the fixed wheel, and the pressurized wire rope bypasses the pressurized wheel. The pressure rope pre-tightening device, the pressurized crown block, the pressurized fixed wheel and the end are fixed on the rotating slips through two direction changing wheels. the

As a preference, the operating system is composed of a large-bore reversing valve, an electromagnetic pilot valve and an electric control handle. the

Preferably, a hole is opened in the middle of the rotating platform, and the derrick cylinder passes through the rotating platform and is rigidly connected to it. the

As a preference, an operation platform is installed at the rear end of the derrick cylinder, and a blowout prevention tool string is installed inside the operation platform. the

As a preference, hydraulic outriggers are installed at the rear and front of the vehicle chassis. the

Compared with the prior art, the beneficial effect of the present invention is: all parts are rigidly fixed on the vehicle frame, the stability is high, and the relocation cost is low; the upper piston rod and the lower piston rod of the derrick oil cylinder are respectively connected to the lifting system Since the hoisting crane in the hoisting crane and the pressurizing crane in the pressurization system are an oil cylinder, the movements of the upper piston and the lower piston are consistent, and there is no potential safety hazard of breaking the steel wire rope due to asynchronous movements of the pistons. The gear is shifted by one key of the electric control handle, which abandons the traditional operation of one or more reversing valves at the same time to complete the gear shifting, reduces the skill requirements for workers, and improves work efficiency; The problem that a long stroke cannot be realized in the process of working with pressure makes the present invention have great advantages in working efficiency. the

Detailed ways

In order to understand the technical solution of the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings. the

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a vehicle-mounted long-stroke working machine with pressure, the rear of the chassis 19 is provided with a rotating platform 12, and the middle part of the rotating platform is opened, and the derrick cylinder 7 passes through the rotating platform 12 Rigidly connected with it, the upper piston rod of the derrick cylinder is connected to the hoisting crane 6, the middle and upper part is fixed to the hoisting wheel 8, the hoisting wire rope 5 passes through the rotating slip 4, the hoisting crane 6 and the hoisting wheel 8, and finally the end of the wire rope is connected to On the pull gauge mechanism 13, a lifting system is formed; the lower piston rod of the derrick cylinder 7 is connected to the pressurized crane 20, the middle and lower part is fixed with a pressurized fixed wheel 9, and the pressurized steel wire rope 3 bypasses the pressurized rope pretensioning device 10, pressurized The crane 20, the pressurized fixed wheel 9, and finally the free end of the pressurized steel wire rope 3 is fixed on the rotating slip 4 through two direction-changing wheels 2 to form a pressurized system, so that the hoisting steel rope 5 and the pressurized system of the hoisting system The pressurized wire rope 3 becomes a closed rope loop through the rotating slip 4. Since the hoisting system and the pressurizing system rely on their own cranes and fixed wheels to enlarge the stroke of the derrick cylinder 7 by four times, the rotating slip 4 The stroke is four times the stroke of the derrick cylinder 7; the operation platform 1 is installed at the rear end of the derrick cylinder 7, and the operation platform 1 is equipped with a blowout prevention tool string, and the blowout prevention tool string installed in the operation platform 1 and the rotating slip 4 work together Next, put out or lower the well pipe string with well suppression; the front end of the automobile chassis 19 is provided with a hydraulic power system 15 and an energy storage system 16, and a power distribution cabinet 18 is arranged next to the hydraulic power system 15; 14 is equipped with an electric control handle, and the electric signal sent by the electric control handle 22 acts on the electromagnetic reversing valve 23, and the electromagnetic reversing valve is used as the pilot valve of the large diameter reversing valve 11, so that one can be controlled simultaneously by the electric control handle 22.
