Description

Technical Field

[0001] The invention belongs to the technical field of oil field field operations, and in particular relates to a mobile auxiliary device for a board house at a pressure operation site. Background Art

[0002] Jilin Oilfield is currently mainly engaged in oil production and auxiliary operations, among which well repair operations are more common. Pressure operations are required on site. In addition to pressure operation equipment, the site also requires board houses. Board houses are mainly used for workers to live, tools to store, and various on-site control devices to store. This brings great difficulties to relocation. A pressure operation site is generally equipped with 7-8 board houses. Due to the large size of the board houses, crane assistance is required during the relocation process, and there are high requirements for the length of the boom. Therefore, cranes of 25 tons and above are used for relocation during the relocation process. Because the site has high requirements for the placement of board houses, relocation is difficult. During the process, the crane is used for a long time. It often takes more than 10 hours to move a site. The crane that pulls the board house has to stand by on site. After lifting one board house, the next board house is far away. The crane needs to retract the boom and legs to change the position and continue lifting. At the same time, due to the well control requirements, the board house must be at the side of the wellhead during the pressure operation. The operation cycle is generally long during the operation, with a short period of 5-7 days and a long period of 10-60 days. When the wind direction changes, the crane must be used to rearrange the board house, which takes more than 10 hours each time, causing great waste of resources for the crane and the board car, and the relocation efficiency is extremely low. There are also great risks in the relocation process. Summary of the invention

[0003] In order to solve the above-mentioned problems, the present invention proposes: a device for assisting the movement of a prefabricated house at a pressure-carrying operation site, comprising a vehicle body, a prefabricated house fixing pin shaft, a connecting sleeve, a cylinder sleeve connecting rod, a liquid cylinder, and a liquid cylinder fixing base. The liquid cylinder fixing base is arranged on the vehicle body, and a liquid cylinder is arranged on the liquid cylinder fixing base. The liquid cylinder sleeve connecting rod is parallel to the horizontal plane of the vehicle body surface. The telescopic hydraulic rod of the liquid cylinder is connected to the center point of the liquid cylinder sleeve connecting rod. A connecting sleeve is arranged at each end of the liquid cylinder sleeve connecting rod. On each of the four vertical surfaces of the prefabricated house, two fixed bases are installed on each surface, a fixed pin shaft is installed on the fixed base, and the connecting sleeve is sleeved on the fixed pin shaft.

[0004] Furthermore, the length of the cylinder sleeve connecting rod is equal to the distance between the fixed pins on two fixed bases on a vertical plane of the board house.

[0005] Furthermore, the connecting sleeve is connected to the fixing pin shaft of the board house through a latch of the fixing connecting piece.

[0006] Furthermore, the vehicle body includes two auxiliary wheels, an auxiliary wheel driving hydraulic motor, and a manual steering wheel. The rear wheels of the vehicle body are provided with two auxiliary wheels, an auxiliary wheel driving hydraulic motor is provided on the vehicle body, the auxiliary wheel driving hydraulic motor is connected to the auxiliary wheels, and a manual steering wheel is provided in the center of the front of the vehicle body.

[0007] Furthermore, a manual steering handle for controlling the steering of the manual steering wheel is provided on the manual steering wheel.

[0008] Furthermore, the diameter of the board house fixing pin is 20 mm.

[0009] Furthermore, the wall thickness of the connecting sleeve is 8 mm.

[0010] Furthermore, the supporting force of the hydraulic cylinder is 2.5 tons and its own weight is within 20 kg.

[0016] In order to make the technical means and objectives of the present invention easy to understand, the present invention is further described below in combination with specific embodiments. A mobile auxiliary device for a prefabricated house on a pressurized operation site, such as Figure 1-Figure 2 As shown, it includes a vehicle body, a fixed pin shaft 1 of a board house, a connecting sleeve 3, a cylinder sleeve connecting rod 4, a cylinder 5, and a cylinder fixed base 8. The cylinder fixed base 8 is arranged on the vehicle body, and the cylinder 5 is arranged on the cylinder fixed base 8. The cylinder sleeve connecting rod 4 is parallel to the horizontal plane of the vehicle body surface. The telescopic hydraulic rod of the cylinder 5 is connected to the center point of the cylinder sleeve connecting rod 4. A connecting sleeve 3 is arranged at each end of the cylinder sleeve connecting rod 4. On the four vertical surfaces of the board house, two fixed bases are installed on each surface, and the fixed pin shaft 1 is installed on the fixed base, and the connecting sleeve 3 is sleeved on the fixed pin shaft 1.

[0017] The length of the cylinder sleeve connecting rod 4 is equal to the distance between the fixed pins 1 on two fixed bases on a vertical plane of the board house.

[0018] The connecting sleeve 3 is connected to the fixed pin shaft 1 of the board house through the latch 2 of the fixed connecting piece.

[0019] Among them, the vehicle body includes two auxiliary wheels 6, an auxiliary wheel driving hydraulic motor 7, and a manual steering wheel 9. Two auxiliary wheels 6 are set on the rear wheels of the vehicle body, and an auxiliary wheel driving hydraulic motor 7 is set on the vehicle body. The auxiliary wheel driving hydraulic motor 7 is connected to the auxiliary wheels 6, and a manual steering wheel 9 is set in the center of the front of the vehicle body.

[0020] Wherein, a manual steering handle 10 for controlling the steering of the manual steering wheel 9 is provided on the manual steering wheel 9 .

[0021] Wherein, the diameter of the board house fixing pin shaft 1 is 20 mm.

[0022] Wherein, the wall thickness of the connecting sleeve 3 is 8 mm.

[0023] The supporting force of the hydraulic cylinder 5 is 2.5 tons, and its own weight is within 20 kg.

[0024] The fixed pin 1 of the board house is designed to have a diameter of 20mm. The shear resistance of a single pin is more than 10 tons, and the deadweight of the board house is generally within 3 tons;

[0025] The latch 2 for fixing the connecting piece is designed to facilitate damage to the invention during transportation, and the device can be disassembled and assembled at any time;

[0026] The connecting sleeve 3 is used to connect the device to the board house, and the designed wall thickness is 8mm, which produces sufficient tensile and torsional strength;

[0027] Cylinder sleeve connecting rod 4, by which the sleeve is connected to the top of the cylinder;

[0028] Cylinder 5, the cylinder support force is 2.5 tons, and the dead weight is within 20kg;

[0029] Auxiliary wheel 6, as the power output end of the board house, has a diameter of 30cm and a tread width of 15cm to prevent the soft ground at the work site from sinking into the ground;

[0030] The auxiliary wheel drives the hydraulic motor 7, which uses a low-speed motor with a rated pressure of 5 MPa and a torque of 200 Nm, which provides a strong driving force while avoiding excessive speed and difficulty in operation;

[0031] The hydraulic cylinder fixed base 8, when the device is moving, will form an angle with the board house. The fixed base is designed as a disc connection. The hydraulic cylinder can rotate freely between the device and no bearing is installed, which greatly improves the running stability and is maintenance-free for life.

[0032] Manual steering wheel 9. During the turning process, the on-site operator performs the turning operation through the steering wheel. The connection principle between the steering wheel and the device is the same as that of the hydraulic cylinder base.

[0033] The manual steering handle 10 is connected to the steering wheel for easy operation. The hydraulic source adopts the hydraulic source of the on-site operation equipment and is designed as a unified hydraulic connection port, which is easy to install and reliable to use, achieving the best board house moving effect.

[0034] In view of the current situation of low lifting efficiency and serious occupation of equipment resources, a prefabricated house moving auxiliary device was invented, which fundamentally solves the drawbacks of the coordination of cranes and shuttle buses for relocation, solves the problem that prefabricated houses need to be placed in different positions, and during the operation cycle, as the wind direction changes continuously, the well control requires the prefabricated houses to be placed at the side air outlet. It solves the problem of serious occupation of equipment resources and low relocation efficiency, and also greatly improves the safety of relocation.

[0035] This invention utilizes a hydraulic cylinder and a hydraulic motor to drive auxiliary wheels, thereby realizing the movement of the prefabricated houses in the absence of cranes or carts on site; it meets the well control requirements in the absence of cranes or carts, and adjusts the position of the prefabricated houses at any time according to the wind direction, and adjusts the position to the side wind outlet; it meets the safety requirements and greatly reduces the idle time during the process of crane lifting the prefabricated houses; it realizes the one-time lifting of all the prefabricated houses by the crane, without the need to frequently retract the boom and legs, and without having to change positions and repeat operations, which greatly saves the waiting time of cranes and carts and improves the utilization efficiency of lifting equipment.

[0036] The effect achieved is as follows:

[0037] 1. Through the on-site experimental application of the invention, the overall use time of cranes and pallet trucks has been greatly reduced. The hoisting time of 7-8 board houses on site has been shortened from about 5 hours to 0.5 hours, and the hoisting efficiency has been greatly improved;

[0038] 2. It effectively reduces the frequency of crane use. Due to well control requirements, the board house must be placed with side vents. It is estimated that the board house is hoisted twice for each well. Based on the calculation of 2,000 wells constructed per year, the board house is hoisted 4,000 times less;

[0039] 3. Improved safety, reducing the number of injuries during lifting by more than 10 times per year on average;

[0040] 4. The crane and shuttle bus can move 2 wells a day, and can move more than 5 wells a day; 5. Economic benefit calculation: ① Reduce investment, increase the lifting speed by 2.5 times, and greatly reduce the number of cranes and pallet trucks required. At present, there are about 100 25-ton cranes and 500 20-ton pallet trucks in Jilin Oilfield. The application of this invention can reduce the number of cranes to 40 and pallet trucks to 200, reducing vehicle purchase investment = 1 million XCMG 25-ton × 40 units + 300,000 × 200 units = 100 million yuan; ② Save time, 2,000 wells can be constructed annually, and 1 well can be constructed annually. The relocation was done an average of 4 times, and each relocation saved 4.5 hours, so the time saved = 2,000 wells × 4 times × 4.5 hours = 36,000 hours; ③ Saving oil and materials: calculated at 30 liters per hour, the oil saved = 36,000 × 30 liters × 7.5 yuan / liter = 8.1 million yuan, and maintenance was done once every 100 hours, which cost 1,000 yuan each time, so the maintenance cost saved = 36,000 ÷ 100 hours × 1,000 yuan = 360,000 yuan; ④ Comprehensive calculation of benefits = ① + ② + ③ = 108.4 million yuan. In addition to saving capital investment, the production and operation efficiency was improved.
