Description

Technical Field

[0001] The utility model belongs to the technical field of oil field drilling, in particular to an oil field drilling explosion-proof electric control box. Background Art

[0002] The explosion-proof electric control box is welded by automatic shielded gas welding. After welding, the surface is treated with a special polishing process. It has a beautiful appearance and a bright stainless steel surface. It is suitable for various highly corrosive and explosive environments. When the explosion-proof electric control box is used in oil field drilling, the display screen and operation panel on the surface of the explosion-proof electric control box need to be protected.

[0003] A Chinese patent with application number CN202222868327.3 discloses an explosion-proof electric control box, which relates to the technical field of electric control boxes, and includes an electric control box body, the top and bottom of the front side of the electric control box body are fixedly connected to a stainless steel frame, a protective plate is movably inserted in the middle of the stainless steel frame, and one end of the protective plate is fixedly connected to a movable push strip.

[0004] The above scheme opens the protective plate by pushing the push handle to both sides, exposing the operation buttons of the electric control box body for the operator to operate. However, in actual use, after pushing the push handle to both sides, it is necessary to continuously apply pressure on the push handle to prevent the protective plate from closing. It is difficult for the staff to complete it independently, the operation is inconvenient, and it causes waste of manpower.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an explosion-proof electric control box for oilfield drilling.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0009] Two storage tubes are installed on both sides of the inner wall of the electric control box body. The inner wall of the storage tube is slidably matched with a hollow tube. One end of the two hollow tubes is fixedly connected with a protective plate, and a pull rope is installed between the roller and the protective plate.

[0010] Optionally, both sides of the inner wall of the electric control box body are provided with wire grooves, and the pull rope cooperates with the wire grooves. By providing the wire grooves, the winding shaft in the wire grooves guides the pull rope, reducing the wear of the pull rope when it is used.

[0011] Optionally, both sides of the inner wall of the electric control box body are provided with limit slots, and both sides of the protective plate are fixedly connected with limit blocks that slide with the limit slots. By providing the limit slots and limit blocks, the movement of the protective plate is guided to increase the stability of the movement of the protective plate.

[0012] Optionally, a mounting groove is provided on one side of the two protection plates, and an observation plate is provided on the inner wall of the mounting groove. By providing the mounting groove and the observation plate, the observation plate is a transparent acrylic plate, which facilitates direct observation of the display screen and improves the convenience of using the device.

[0013] Optionally, one side of one of the two protective plates is fixedly connected with two trapezoidal blocks, and one side of the other of the two protective plates is provided with two trapezoidal grooves that match the trapezoidal blocks. The trapezoidal blocks and the trapezoidal grooves are provided to guide the connection of the two protective plates, so that the protective plates are more tightly connected.

[0014] In this embodiment, a return spring is installed between the two protection plates and the electric control box body, and the return spring cooperates with the storage tube. The return spring is provided to apply pressure to the protection plate so that the protection plate protects the operation panel on the electric control box body.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0016] By setting a pull rope, when the protective plate needs to be opened, the driving block is pulled, the driving block drives the rack to move, the rack drives the gear to rotate, the gear rotation drives the roller to rotate, and the roller pulls the pull rope when rotating. Under the transmission of the pull rope, the pull rope drives the protective plate to move and open, which is convenient for operating the control button on the electric control box body. When the operation is completed, the driving block is released, and under the action of the reset spring, the driving block is reset. It can be operated by one person, saving labor.
