Description

Technical Field

[0001] This utility model relates to the field of petroleum machinery and equipment technology, specifically to a walkway railing that can be quickly folded and stored at the drilling and well workover site. Background Technology

[0002] In the field of oilfield machinery and equipment, walkways and guardrails are used to connect various components, primarily serving to facilitate personnel movement and prevent falls. During well site relocation, due to road transport size limitations and local legal regulations, all walkways and guardrails need to be dismantled. A typical workover rig consists of modules such as the main engine vehicle, power trailer, gas source trailer, and mud tank trailer. Each module, as an independent unit, is equipped with walkways for easy personnel access and guardrails to prevent falls. The installation and dismantling of these walkways and guardrails involves a significant number of components. Traditionally, this involves repeatedly installing each walkway using cranes, forklifts, and personnel, followed by the repetitive installation of each guardrail using cranes, forklifts, and personnel – a time-consuming process. This not only increases the labor intensity of personnel but also significantly increases the operating costs of on-site equipment and extends the well site relocation time, failing to meet the customer's requirement for rapid relocation of modules. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a walkway railing that can be quickly folded and stored at the drilling and workover site, which can solve the technical problems of high labor intensity, long time and high cost caused by the need to repeatedly disassemble and assemble walkways and railings when moving well sites.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A walkway railing for quick folding and storage at drilling and workover sites includes a modular main beam. A walkway and railing are located on one side of the main beam. One end of the walkway is hinged to the main beam, and the other end is folded upwards via a power mechanism fixed to the main beam. The railing is connected to the main beam via several rotating support mechanisms. Each rotating support mechanism includes a double-eared seat welded to the main beam and bolted to one end of the rotating support main beam. The railing is connected to the other end of the rotating support main beam via a cotter pin. The rotating support main beam has pin holes, and the main beam has a stop pin that engages with the pin holes for locking.

[0006] Preferably, one end of the walkway is connected to the main beam of the module via a hinge, and the bottom of the other end is provided with a limiting plate, the width of the inner groove of the limiting plate being clearance-fitted with the width of the rotating support main beam.

[0007] Preferably, the walkway includes a frame, within which a fiberglass grating is provided, and a latch is provided on one side of the frame.

[0008] Preferably, the power mechanism includes a hand-cranked winch, and the wire rope on the hand-cranked winch is connected to the free end of the walkway frame via pulleys.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model can realize the quick folding of walkways and guardrails, shorten the well site relocation time, reduce the labor intensity caused to personnel by repeated disassembly and assembly of walkways and guardrails, reduce the use cost of on-site cranes, forklifts and other equipment, and reduce the impact and damage to surrounding parts caused by repeated disassembly and assembly.

Detailed Implementation

[0020] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0021] like Figures 1 to 7 As shown, this utility model discloses a walkway railing that can be quickly folded and stored at the drilling and workover site. It includes a modular main beam 1, with a walkway 2 and a railing 3 on one side of the main beam 1. One end of the walkway 2 is hinged to the main beam 1, and the other end is driven by a power mechanism to fold upwards by 90°. The power mechanism is fixed to the main beam 1. The railing 3 is connected to the main beam 1 via several rotating support mechanisms 4. The rotating support mechanisms 4 support the walkway 2 and fix the railing 3. Each rotating support mechanism 4 includes a double-eared seat 41, which is welded to the main beam 1. The double-eared seat 41 is connected to one end of the rotating support main beam 43 via bolts 42. The railing 3 is connected to the other end of the rotating support main beam 43 via a cotter pin 5. The rotating support main beam 43 has a pin hole 44, and the main beam 1 has a stop pin 6. The stop pin 6 cooperates with the pin hole 44 to achieve locking.

[0022] Furthermore, in this embodiment, one end of the walkway 2 is connected to the main beam 1 of the module via a hinge 7, and the bottom of the other end is provided with a limiting plate 8, the width of the inner groove of the limiting plate 8 being clearance-fitted with the width of the rotating support main beam 43.

[0023] When the rotating support mechanism 4 is used to support the walkway 2, the support is perpendicular to the module main beam 1 so that the walkway 2 can be placed on the support. At this time, the limiting plate 8 on the walkway 2 is fixed to the rotating support main beam 43, which can ensure the stability of the rotating support.

[0024] When the transport unit needs to be moved, the bolt 42 rotates, making the rotating support main beam 43 parallel to the module main beam 1, and the support is locked by the stop pin 6.

[0025] Furthermore, in this embodiment, the walkway 2 includes a frame 21, which is made of low-density profiles; the frame 21 is provided with a fiberglass grating 22, which makes the overall weight of the walkway 2 lighter and easier for manual operation; a pin 23 is provided on one side of the frame 21, which helps to fix the folded walkway 2.

[0026] Furthermore, in this embodiment, the power mechanism includes a hand-cranked winch 9, and the wire rope on the hand-cranked winch 9 is connected to the free end of the walkway frame 21 through a pulley 10; by operating the hand-cranked winch 9, the pulley 10 is driven, thereby pulling the free end of the walkway frame 21 upward to fold up. When the walkway 2 is folded up to 90°, the pin 23 is manually inserted to achieve the purpose of vertical transportation of the walkway 2.

[0027] Working principle: When in use, first open the stop pin 6, and the operator rotates the rotating support main beam 43 to open the guardrail 3. Then, push open the latch 23 and drive the walkway 2 downward by the hand-cranked winch 9 until the limit plate 8 contacts and is fixed with the rotating support main beam 43. The walkway is then ready for use. When moving and storing, first fold the walkway 2 upward by 90° using the hand-cranked winch 9, insert the latch 23 to fix it, then rotate the rotating support main beam 43 to move the guardrail 3. Finally, lock it with the stop pin 6 to complete the storage.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
