Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a transportation device for oil pipes and sucker rods. Background Technique

[0002] At present, most oilfields use traditional equipment for placing oil pipes. Generally, two workers are required to drag and carry the oil pipes on the well site, responsible for the placement of the oil pipes between the wellhead and the pipe rack. The working environment is harsh, the labor intensity of the workers is high, the floor area of the placement equipment is large, and there are also potential safety hazards during the operation. There is a problem of crude oil pollution during the transportation and placement of the oil pipes. The on-site placement of the oil pipes occupies a large area, which is inconvenient for construction.

[0003] At present, during the operation of pulling out and lowering oil pipes at the production site of oilfield workover operations, a kind of bridge seat is usually used, which is commonly known as an oil pipe bridge on the site. When carrying out workover operations, it is necessary to carry out conventional operations of lowering and retrieving oil pipes. The traditional mode is to use three oil pipe bridges as the base, and arrange the oil pipes neatly in layers on the oil pipe bridges. The oil pipes are transported to or retrieved from the wellhead platform manually. There are two ways to transport or retrieve the oil pipes: one is to use two oil pipes as sliding rails and use a small trolley to transport the oil pipes. The other is to use an oil pipe conveyor. The worker manually moves the oil pipe to the small hook of the conveyor, the small hook lifts the oil pipe, and flips the oil pipe to the chute of the oil pipe conveyor, and then transports the oil pipe to the wellhead. This traditional operation mode has environmental protection problems, high labor intensity of workers, and potential safety hazards. The area of the oil pipe bridge is large. In order to prevent the crude oil and sewage in the pipe from falling to the ground, it is necessary to lay a large area of oil-proof plastic cloth and fences under it, which not only has high costs, but also is easy to be damaged. If it is reused, the cleaning is very cumbersome. Content of the Utility Model

A plurality of frames are stacked between the four columns 7. The lowermost frame is fixedly connected to the base 6, and the remaining frames are slidably connected to the columns 7. The upper and lower adjacent frames are connected by a plurality of vertical first oil cylinders 9.

[0033] The frame includes a bracket 8 in an inverted U shape, and the open end of the bracket 8 faces the special loading and unloading vehicle for oil pipes and sucker rods.

[0034] A plurality of longitudinally arranged support rods 13 are fixed on the straight parts of the bracket 8, and a storage cavity is formed between the upper and lower adjacent support rods 13.

[0035] A support unit and a push plate 17 are slidably arranged in the storage cavity. The push plate 17 is located in front of the support unit, and the support unit is in movable contact with the support rods 13 on its upper and lower sides.

[0036] Drive units are arranged in the brackets 8 below the storage cavity. The drive units include telescopic rods 15. The telescopic rods 15 are parallel to the support rods 13. The front ends of the telescopic rods 15 are fixedly connected to the brackets 8, and the rear ends of the telescopic rods 15 are fixedly connected to the rear ends of the connecting plates 16.
