Example Embodiment

[0016] see figure 1 , 2 , which are the structural schematic diagram of a trolley for detecting and sending and receiving equipment for oil and natural gas pipelines according to the present invention. As shown in the figure: it is assembled by a carrying device, a booster device, a power system and a moving device.
[0017] Its specific structure is as follows:
[0018] The bearing device includes a circular arc bearing plate 9, 4-10 bottom reinforcing ribs 6, 2-4 bearing beams 5, 4-8 supporting hydraulic cylinders 11, 2-4 base beams 22 and 4-8 The base bearing platform 20; wherein: the arc bearing plate 9 and the bottom reinforcing rib 6 are connected together by welding, the bottom reinforcing rib 6 and the bearing beam 5 are welded together, and the bearing beam 5 is connected with the supporting hydraulic cylinder 11 through the first pin 8 Together, the supporting hydraulic cylinder 11 and the base beam 22 are connected together by a first screw 21 , and the supporting hydraulic cylinder 11 and the base bearing platform 20 are connected together by a second pin 18 . The carrying device remains stable during the working process and can bear the weight of 0.1~10 tons.
[0019] The booster device includes a large hydraulic cylinder 2, a rear support base 1, a front support base 3, 1-5 connecting rods 10 and several hooks 4; wherein: the large hydraulic cylinder 2 is fixed on the front support base 3. And on the rear support base 1 , the connecting rod 10 is connected with the large hydraulic cylinder 2 through the first pin 8 ; a plurality of hooks 4 are arranged on the hydraulic rod of the large hydraulic cylinder 2 . Wherein: the connecting rod 10 is connected with the large hydraulic cylinder 2 through the first pin 8, and the connecting rod 10 will not be used when the pushing stroke is within the required range. In the working process, the connecting rod 10 is increased or decreased according to the actual situation, and the lifting hook 4 is disassembled to complete the pushing and pulling work, and the booster device provides a pushing force or pulling force of 0.1-10 tons, and can keep moving continuously.
[0020] The power system includes a hydraulic cylinder 13, a number of high-pressure oil pipes 12, 23, a motor 14 and an oil pump 15; wherein: the hydraulic cylinder 13 is provided with an oil pump 15 controlled by the motor 14, and the oil pump 15 passes the first high pressure. The oil pipe 12 is connected to the large hydraulic cylinder 2 , and the oil pump 15 is connected to the support hydraulic cylinder 11 through a second high-pressure oil pipe 23 .
[0021] The moving device includes several universal wheels 17 and several second screws 24 ; the universal wheels 17 are connected with the base beam 22 through the second screws 24 . Under the action of external force, the universal wheel 17 slides and rubs with the ground, so that the equipment can move quickly and save time and effort.
[0022] In addition, as a preferred structure, the connecting rod 10 is inserted through the hole 25 of the bottom reinforcing rib 6 .
[0023] Furthermore, the power system also includes several throttle valves 16 and several regulating valves 7, 19; the oil pump 15 is connected to the large hydraulic cylinder 2 through the first high pressure oil pipe 12 with the first regulating valve 7, and the oil pump 15 passes through the A second high-pressure oil pipe 23 with a second regulating valve 19 is connected to the support hydraulic cylinder 11 ; a throttle valve 16 is provided at the connection between the oil pump 15 and the high-pressure oil pipes 12 and 23 . The power system can be adjusted through the regulating valve 7 , regulating valve 19 , and throttle valve 16 according to the actual required pressure, and fully meet the weight and thrust required to be provided.
[0024] When the present invention is used, the present invention provides power to the oil pump 15 through the motor 14, and at the same time, the oil pump 15 converts the power transmitted from the motor 15 into pressure and transmits it to the support hydraulic cylinder 11 so that the height of the trolley can be adjusted and the base bearing platform 20 is supported on the ground. And to meet the requirements of use, adjust the trolley through the regulating valve 19 to keep it flat and horizontal. Place the testing equipment on the bearing arc plate 9 and keep it still, close the regulating valve 19 between the supporting hydraulic cylinders, adjust the height and parallelism of the large hydraulic cylinder 2 through the rear support seat, adjust the large hydraulic cylinder 2, and open the regulating valve 7 , the oil pump 15 continues to provide pressure to the large hydraulic cylinder 2. Under the action of hydraulic pressure, the large hydraulic cylinder 2 moves linearly on the bearing beam 5, and pushes the detection equipment to move until the detection equipment is pushed into the designated position, and the detection equipment is launched. success.
[0025] In the process of receiving the testing equipment, when the testing equipment is completed, the testing equipment is pushed to the pipe opening through the internal pressure of the pipeline, the height and parallelism of the trolley are adjusted, and the supporting base is fixed by the supporting hydraulic cylinder 11, and the motor 14 continues to provide the oil pump 15. Power, the oil pump 15 converts the power into pressure and transmits it to the large hydraulic cylinder 2, the hydraulic rod extends to the desired length, connects the hook 4 with the testing equipment, opens the regulating valve, and the large hydraulic cylinder 2 under the action of high pressure oil The inspection equipment is pulled out from the pipe mouth and moved on the arc bearing plate until the inspection equipment is completely pulled out of the pipe, and the work of the inspection equipment is completed.
[0026] To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made according to the content of the patented scope of the present invention shall fall within the technical scope of the present invention.
