Description

Technical Field

[0001] The utility model relates to the technical field of petroleum well repairing equipment, in particular to a pipe laying machine with adjustable crossbeam length. Background Art

[0002] During oil well repair, it is necessary to arrange the pipes and rods (oil pipes and pumping rods) pulled out of the oil well in an orderly manner, or to transport the pipes and rods arranged in the oil pipe warehouse to the wellhead equipment for the oil pipe lowering operation. At present, the oil pipe pulling and lowering operations during oil well repair are mostly carried out by mechanical equipment.

[0003] For the lifting / lowering of pipe rods, pipe laying machines are mostly used for orderly discharge. Most of the existing pipe laying machines used for oil well repair use pipe rod grippers to grab, move and discharge pipe rods above the pipe laying equipment. The pipe laying machine of this structure needs to set a long and heavy connecting beam above the pipe laying space, and the pipe rod gripper is connected to the bottom of the connecting beam. The two ends of the connecting beam are respectively slidably set on the guide rails. This pipe laying machine has a complex structure, large overall size, heavy weight, inconvenient transportation, and strict site requirements.

[0004] In addition, in the process of oil well repair, in order to facilitate transportation, the height of the support column of the cantilever pipe laying machine and the width of the pipe laying are generally not large. This results in the cantilever and the moving mechanism on the cantilever often interfering with the oil pipe and other equipment during the use of the cantilever pipe laying machine, affecting the promotion and application of the cantilever pipe laying machine.

[0005] If the width of the pipes in the pipe laying machine is too small, the height of the pipes will inevitably increase under the same load, resulting in requirements for the height of the support columns in the pipe laying; not only does the pipe laying operation require a high height, but it also poses a safety hazard to mobile transportation. Utility Model Content

[0006] The utility model aims to solve the problems that the pipe laying height of the existing cantilever pipe laying machine is too high, the height of the existing support columns and the width of the pipes are generally not large, and it is difficult to meet the transportation and work requirements at the same time, and provides a pipe laying machine with adjustable crossbeam length.

[0007] The utility model is realized by the following technical scheme: a pipe laying machine with adjustable crossbeam length, comprising a support frame and a telescopic cantilever; the support frame comprises a bottom support and a vertical support perpendicular to each other, a ship-shaped cofferdam for placing oil pipes is arranged on the bottom support, and a telescopic cantilever perpendicular to the vertical support is arranged above the ship-shaped cofferdam;

[0008] A lifting and moving mechanism is provided at the bottom of the telescopic cantilever, and at least one oil pipe grabbing mechanism is provided at the bottom of the lifting and moving mechanism. The lifting and moving mechanism comprises a lifting mechanism and a moving mechanism which are perpendicular to each other, and the moving mechanism moves along the width direction of the telescopic cantilever.

[0009] Further, the telescopic cantilever comprises an inner frame, a sliding body and a linear telescopic mechanism;

[0010] The inner frame is vertically mounted on the vertical bracket of the support frame; the sliding body is a hollow structure located outside the inner frame and is slidably connected to the inner frame;

[0011] The two ends of the linear telescopic mechanism are respectively mounted on the sliding body and the crossbeam of the inner frame.

[0012] Furthermore, a sliding groove and a load-bearing cross beam are provided on the inner wall of the sliding body, and the load-bearing cross beam is fixedly arranged on the upper side of the inner wall of the sliding body perpendicular to the inner wall.

[0013] Furthermore, a supporting beam is provided on the inner frame, and two ends of the linear telescopic device are respectively fixedly connected to the upper surface of the supporting beam and the lower surface of the load-bearing beam.

[0014] Furthermore, the lifting mechanism is a liftable scissor-type structure, and the scissor-type structure is connected to a lifting cylinder for driving the scissor-type structure to lift and lower.

[0015] Furthermore, the moving mechanism is a reciprocating multi-stage telescopic fork, which includes a telescopic arm, a power motor, a transmission mechanism and a linkage mechanism; the telescopic arm includes at least two layers of fork arms.

[0016] Furthermore, the oil pipe grabbing mechanism is an electro-permanent magnet.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] (1) The pipe laying machine with adjustable crossbeam length of the utility model utilizes the bottom support and vertical support of the support frame, and the telescopic cantilever mounting frame to achieve the adjustment of the cantilever length (the cantilever length erected above the pipe stacking area), and the cantilever length adjustment range is large;

[0019] (2) The telescopic boom advance and lift mechanism of the utility model increases the height of the boom in the working state by using an adjustable height lifting mechanism to avoid interference between the boom and the oil pipe slideway; during the transportation of the cantilever pipe laying machine, the height of the support column is adjusted to be small for easy transportation;

[0020] (3) The telescopic cantilever and lifting moving mechanism of the utility model increases the cross-span of the pipe laying machine when in working state by using a moving mechanism with adjustable lateral width, thereby avoiding the situation where the pipes are laid too high under the same load; during the transportation of the cantilever pipe laying machine, the width of the pipes is increased and the height of the pipes is reduced, thereby facilitating transportation.
