In addition, the stacked pipe rods are not prone to collapse, and potential safety hazards are avoided.

Description

Technical Field

[0001] This utility model belongs to the field of oil well operation technology, specifically relating to a rod support frame for oilfield well workover operations. Background Art

[0002] An oil well is a hole drilled according to the well layout system of an oilfield development plan for the purpose of extracting oil. It is the channel through which oil rises from the bottom of the well to the wellhead. When performing well workover operations, a large number of pipes are needed. People often use special pipe racks to arrange the numerous pipes for centralized storage.

[0003] The existing pole racks have certain drawbacks in use. First, it is not convenient to access the poles inside the rack. Second, the racks are stacked with a large number of poles, which can easily collapse if care is not taken when accessing them, posing a safety risk. Therefore, a new type of pole rack needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a rod rack for oilfield well workover operations, so as to solve the problems mentioned in the background art of the inconvenience of accessing the internal rods and the safety hazards during access when using the existing rod racks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oilfield well workover operation rod rack, comprising a placement rack and rods stacked inside the placement rack. A discharge chute is provided at the bottom of one side of the placement rack. A discharge assembly is provided on the outside of the discharge chute on one side of the placement rack. The discharge assembly includes a baffle, a receiving plate, and a connecting rod. The baffle has an L-shaped structure and is slidably connected to one side surface of the placement rack. The receiving plate is located at the bottom of the baffle. The connecting rod is fixedly connected between the two ends of the baffle and the receiving plate. A spring assembly is provided between the top of the baffle and one side of the placement rack.

[0006] Preferably, the length and height of the unloading trough are adapted to a single pipe rod, and the bottom surface of the placement frame is inclined and tilted towards the unloading trough.

[0007] Preferably, the spring assembly includes a fixing plate and a spring, the fixing plate being fixed to one side surface of the placement frame and located directly above the baffle, and the spring being fixedly connected between the fixing plate and the baffle.

[0008] Preferably, the receiving plate has a V-shaped structure, and a rubber pad is provided on the inner side of the receiving plate.

[0009] Preferably, the discharge assembly further includes a slide bar and a chute, wherein the slide bar is fixed to one side of the baffle and slidably connected to the chute formed on the surface of the placement frame.

[0010] Preferably, the slide bar has a T-shaped structure when viewed from above, and the outer surface of the slide bar is adapted to the inner wall of the slide groove.

[0011] Preferably, the bottom of the placement rack is provided with a base, and a base frame is fixedly connected between the base and the bottom of the placement rack.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The designed rack allows for centralized storage of pipes, with a single pipe placed on a receiving plate. The weight of this pipe pulls down a baffle, which blocks the unloading chute from the outside, thus preventing the remaining pipes inside the rack from falling out. To retrieve a pipe, simply remove it from the receiving plate. The baffle, pulled by a spring assembly, moves upward, exposing the unloading chute. A pipe then falls from inside the rack into the receiving plate. Pressing down the baffle again blocks the unloading chute from the outside, preventing the remaining pipes from falling out. By continuously removing pipes from the receiving plate, they will fall one by one onto the receiving plate. This design not only facilitates pipe retrieval but also prevents the stacked pipes from collapsing, thus avoiding safety hazards. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example

[0021] Please see Figures 1 to 4 This embodiment of the present invention provides a technical solution: an oilfield well workover operation rod rack, including a placement frame 100 and rods 700 stacked inside the placement frame 100. A discharge chute 200 is provided on one side of the bottom of the placement frame 100, allowing the rods 700 inside the placement frame 100 to fall out through the discharge chute 200. A discharge assembly 300 is provided on one side of the placement frame 100 outside the discharge chute 200. The discharge assembly 300 includes a baffle 301, a receiving plate 302, and a connecting rod 303. The baffle 301 has an L-shaped structure and is slidably connected to one side surface of the placement frame 100. The baffle 301 can slide up and down; after sliding down... The baffle 301 can block the unloading chute 200. After sliding upwards, the unloading chute 200 is open. The receiving plate 302 is set at the bottom of the baffle 301. The connecting rod 303 is fixedly connected between the two ends of the baffle 301 and the receiving plate 302. The tube rod 700 falling from the unloading chute 200 can fall into the receiving plate 302. A spring assembly 400 is provided between the top of the baffle 301 and one side of the placement frame 100. The spring assembly 400 can pull the baffle 301 upwards. When there is no tube rod 700 on the receiving plate 302, the spring assembly 400 can pull the baffle 301 to the top. When the tube rod 700 falls onto the receiving plate 302, the weight increases and the baffle 301 slides down.

[0022] In this embodiment, preferably, the length and height of the unloading trough 200 are adapted to the individual pipe rods 700, so that the pipe rods 700 can fall down from the unloading trough 200 one by one. The bottom surface of the placement frame 100 is inclined and tilted towards the unloading trough 200, so that the pipe rods 700 can gather towards the unloading trough 200.

[0023] In this embodiment, preferably, the spring assembly 400 includes a fixing plate 401 and a spring 402. The fixing plate 401 is fixed to one side surface of the placement rack 100 and located directly above the baffle 301. The spring 402 is fixedly connected between the fixing plate 401 and the baffle 301, and the baffle 301 can be pulled up by the spring 402.

[0024] In this embodiment, preferably, the receiving plate 302 has a V-shaped structure, and a rubber pad is provided on the inner side of the receiving plate 302. When the tube rod 700 falls, the rubber pad plays a buffering role.

[0025] In this embodiment, preferably, the discharge assembly 300 further includes a slide bar 304 and a slide groove 305. The slide bar 304 is fixed to one side of the baffle 301 and is slidably connected to the slide groove 305 opened on the surface of the placement frame 100. The slide bar 304 has a T-shaped structure when viewed from above. The outer surface of the slide bar 304 is adapted to the inner wall of the slide groove 305 to realize a stable lifting connection between the baffle 301 and the placement frame 100.

[0026] In this embodiment, preferably, a base 600 is provided at the bottom of the placement rack 100, and a base frame 500 is fixedly connected between the base 600 and the bottom of the placement rack 100 to support the placement rack 100.

[0027] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
