Continuous large-power turbine fracturing equipment

The invention discloses continuous large-power turbine fracturing equipment. The large-power turbine fracturing equipment comprises a turbine engine, a reduction box, a transmission shaft and a plunger pump, wherein the turbine engine and the reduction box are arranged on the same straight line; the reduction box is connected to the plunger pump through a transmission shaft; and an angle of the transmission shaft ranges from 2 degrees to 4 degrees. The continuous large-power turbine fracturing equipment has the beneficial effects that: a chassis T1 material is selected, so that a stable working platform is provided for the equipment; the turbine engine and the reduction box are on the same straight line, the transmission shaft is arranged between the reduction box and the plunger pump, andthe angle of the transmission shaft ranges from 2 degrees to 4 degrees, so that stable and efficient transmission of the turbine engine is guaranteed, and a fault occurrence rate is reduced; a lubricating system driven by an auxiliary power system guarantees that the turbine engine, the reduction box and the plunger pump work under a proper environment; dual lubricating systems guarantee that theplunger pump realizes continuous operation under power of 5000 HP or higher; and the technical means finally can meet continuous large-power operation requirements of the fracturing equipment.

Fracturing blender truck

The invention provides a fracturing blender truck. The fracturing blender truck comprises a chassis, a sand blending device, a four-connecting-rod mechanism and a power system. The sand blending device is arranged above the chassis and provided with a sand blender, and a closed-type mixing pump serves as the sand blender. The four-connecting-rod mechanism is capable of driving the sand blending device to move to enable a base of the closed-type mixing pump to contact with the ground, a first connecting rod and a third connecting rod of the four-connecting-rod mechanism are arranged on the chassis rotatably, and the sand blending device is arranged on a second connecting rod of the four-connecting-rod mechanism. The power system arranged on the chassis is connected with the first connecting rod and drives the four-connecting-rod mechanism to rotate to enable the closed-type mixing pump to contact with the ground. The fracturing blender truck has the advantages that the closed-type mixing pump serves as the sand blender, and the second connecting rod of the four-connecting-rod mechanism is used for bearing the sand blending device to enable the base of the closed-type mixing pump to be capable of contacting with the ground, so that the height of the closed-type mixing pump is decreased, suction capacity of the closed-type mixing pump is improved, a great quantity of fracturing fluid can be guided out, delivery capacity of the fracturing blender truck is increased, and the requirements on large-scale fracturing operation can be met.

The invention discloses an automatic recovery and placing vehicle for traffic road cones. The vehicle comprises a vehicle chassis (1), a road cone recovery and placing device (2), a road cone delivery and storage device (3), a road cone transverse pushing mechanism (5), a road cone guiding mechanism (4), an electric device control cabinet (6) and a generator set (7), wherein the road cone recovery and placing device (2) is used for placing and recovering road cones, the road cone delivery and storage device (3) and the road cone transverse pushing mechanism (5) are used for delivering road cones onto the road cone recovery and placing device (2), the road cone guiding mechanism (4) is used for adjusting directions and positions of road cones, and the electric device control cabinet (6) and the generator set (7) serve as a vehicle control and power source. According to the vehicle, both advanced mechanical control technologies and advanced electric control technologies are used to finish automatic recovery and placing of traffic road cones, and the automatic recovery of road cones in a left traffic lane, a right traffic lane and a middle traffic lane can be achieved. During the automatic recovery of road cones, the vehicle moves backwards, and a liquid crystal monitoring screen and vehicle reflectors are used for path positioning. A storage box is hung on a vehicle body and is automatically recovered onto the vehicle chassis under the non-working condition, and the width of the vehicle body is not affected.
