The utility model provides a coiled tubing drilling machine cylinder transport vechicle adopts the formula of cutting off structure, divide into first section frame 8, second section frame 4, third section frame 9, and the second end frame is rectangular frame simultaneously, so can make the lower terminal surface of setting up the coiled tubing cylinder 5 on the second frame sink and exceed the second frame. Simultaneously, coiled tubing rig cylinder transport vechicle in this application all sets up driving system 1 and transmission system 2 on third section frame 9, and drive rear axle 3 through driving system 1, so make the below of second frame need not set up transmission shaft 14 to drive front axle 6, consequently, the sunken range of coiled tubing cylinder 5 on the second frame can greatly increased, under the condition that satisfies whole car trafficability characteristic, and under the same basic prerequisite of car overall height, the diameter of coiled tubing cylinder 5 in this application can be bigger, its winding capacity that can furthest't improve the cylinder.
To better understand the coiled tubing rig drum transport cart of the present application, it will be further explained and illustrated below. As shown in fig. 1 and 2, the vehicle frame includes: the frame comprises a first section of frame 8, a second section of frame 4 and a third section of frame 9, wherein the second section of frame 4 is a rectangular frame, and the second section of frame 4 is positioned between the first section of frame 8 and the third section of frame 9. The length of the first section of frame 8 and the third section of frame 9 can be relatively shorter, so that the processing is easier, the processing and heat treatment difficulty is effectively reduced, and the cost is favorably reduced. Fig. 4 is a schematic structural diagram of a second section frame 4 of a roller conveyor of a coiled tubing drilling machine in an embodiment of the invention, and as shown in fig. 4, the second section frame 4 in a rectangular frame comprises: the frame structure comprises a first cross beam 41, a second cross beam 42, a first vertical beam 43 and a second vertical beam 44, wherein the first vertical beam 43 and the second vertical beam 44 are connected to two ends of the first cross beam 41 and the second cross beam 42, the first section of frame 8 is connected with the second vertical beam 44, and the third section of frame 9 is connected with the first vertical beam 43.
In order to ensure the connection strength, the first section frame 8 and the second vertical beam 44 may be connected by welding, the third section frame 9 and the first vertical beam 43 may be connected by welding, and the welding strength may be achieved by enlarging the welding area.
The first cross beam 41, the second cross beam 42, the first vertical beam 43 and the second vertical beam 44 can be connected by welding. The first vertical beam 43 and the second vertical beam 44 of the second section frame 4 which is a rectangular frame are a complete straight beam, so that the continuity of the whole structure can be ensured, and the whole frame has no stress catastrophe points. Meanwhile, the distance between the first section of frame 8 and the third section of frame 9 can be adjusted at will, so that the gap between the first section of frame 8 and the third section of frame 9 can be larger, and thus, the size of the continuous pipe roller 5 arranged on the second section of frame 4 can be increased, so that the winding capacity of the roller can be increased; the distance between the first section of frame 8 and the third section of frame 9 can be adjusted at will, and the wheelbase can be adjusted conveniently, so that chassis of different varieties can be produced.
As shown in fig. 1, a first supporting mechanism 10 is disposed on the first beam 41, a second supporting mechanism 11 is disposed on the second beam 42, and two ends of the shaft of the continuous tube drum 5 are disposed on the first supporting mechanism 10 and the second supporting mechanism 11, respectively. The continuous tube roll 5 is arranged on the second frame section 4 in the above-described manner. Since the second-stage carriage 4 is a rectangular frame, the frame of the continuous tube drum 5 can be sunk to the middle of the second-stage carriage 4 so that the lower end face of the rim of the continuous tube drum 5 is lower than the second-stage carriage 4, and the edge of the rim of the continuous tube drum 5 abuts against the first vertical beam 43 and the second vertical beam 44. In a preferred embodiment, the height of the second frame section 4 may be higher than the height of the first frame section 8 and the second frame section 4, so that the sinking distance of the lower end surface of the continuous pipe roller 5 can be effectively increased, and the winding capacity of the roller can be further improved.
Fig. 3 is a schematic structural diagram of a power system 1 and a transmission system 2 on a third-stage frame 9 in an embodiment of the present invention, and as shown in fig. 1, fig. 2, and fig. 3, the power system 1, the transmission system 2, and a rear axle 3 are disposed on the third-stage frame 9, and the power system 1 includes: an engine 16 and a gearbox 15 in transmission connection with the engine 16. The engine 16 and the gearbox 15 are arranged on the table top of the third section frame 9. The transmission system 2 may then comprise: the transfer case 13 is in transmission connection with the transmission shaft 14, and is in transmission connection with the hydraulic pump 12 and the rear axle 3 respectively. The hydraulic pump 12 may be used to drive the coiled tubing drum 5 in rotation. Because the engine 16 is arranged on the table top of the third section frame 9, the engine can directly drive the rear axle 3 so as to enable the rear axle 3 to become a driving axle, the front axle 6 of the continuous pipe drilling machine roller transport vehicle is a non-driving axle, and the continuous pipe drilling machine roller transport vehicle can steer, so that the transmission structure is simplified, power is transmitted to the rear axle 3 and the hydraulic pump 12 through the transfer case 13, the power configuration is optimized, and the upper-mounted roller operation and chassis running can share one set of power system 1. Meanwhile, the engine 16 is arranged at the rear part, and the driving mode is used for rear driving, so that the transmission shaft 14 does not need to be arranged below the roller, and the phenomenon that the rim of the roller is required to be positioned above the transmission shaft 14, which has a large influence on the capacity of the roller, is avoided. Through the structure, the drum sinking amount can be further increased under the condition of meeting the passing property of the whole vehicle, and the winding pipe capacity is increased on the premise of keeping the overall dimension of the whole vehicle unchanged. Moreover, the engine 16 is arranged on the table of the third section frame 9, so that the engine 16 and the gearbox 15 can be easily arranged, fixed and overhauled, and the selection of the engine 16 is diversified and is not limited by any space.
As shown in fig. 1 and 2, the cab 7 and the front axle 6 may be disposed on a first-stage frame 8, the first-stage frame 8 being a front end of a continuous pipe drill drum transport vehicle.
