Abstract

The invention relates to the technical field of a gas spring opening and closing door of a rotary drilling rig cover element, and particularly relates to a gas spring opening and closing door of a rotary drilling rig cover element. The gas spring opening and closing door of the rotary drilling rig cover element comprises a door lock, a handle, a door, a gas spring, a link stopper and a door frame, wherein the top end of the door is hinged with the top end of the door frame; the gas spring is arranged between the middle section of the door and the middle of the door frame for connection; the handle is arranged on the door; a door lock is arranged at the tail end of the door, and the link stopper is arranged at the lower end of the door frame. Opening and shutting of the door of the cover element become quite convenient; the door is fixed at the maximal position by self-lock of the gas spring, and does not fall off, so that a manual limiting rod in the traditional mode is saved.

Description

Rotary drilling rig cladding element gas spring switching door

Technical field

The present invention relates to rotary drilling rig covering switching door technical field, especially a kind of rotary drilling rig cladding element gas spring switching door.

Background technology

Existing door-opening mode generally adopts hinge to lean on the manpower folding, and sight line is blocked in effort and horizontal folding meeting, repairs inconvenience, and area occupied is also larger.Realize that at present switching door mainly adopts the mode of accompanying drawing 2, accompanying drawing 3: door and doorframe are connected through the hinge, and realize 90 ° of opening and closing left and right.The folding of this kind mode door and hinge be manufactured with much relations, hinge as lubricated will be so that door folding difficulty and send the ear-piercing sound, open angle is also restricted, repairing to have good visual angle, when door reached maximum, the movement of gag lever post meeting lock door was if want to close to the doorstep, must manually gag lever post be shifted out from lockhole, be very much trouble.

Summary of the invention

In order to overcome the deficiency of existing technology, the invention provides a kind of rotary drilling rig cladding element gas spring switching door.

The technical solution adopted for the present invention to solve the technical problems is: a kind of rotary drilling rig cladding element gas spring switching door, comprise door lock, handle, door, air spring, collision block, doorframe, top and the doorframe top of door are hinged, the door interlude is provided with air spring with the doorframe centre and is connected, door is provided with handle, the end of door is equipped with door lock, and collision block is equipped with in the doorframe lower end.

The invention has the beneficial effects as follows, the invention enables the folding of covering door to become particularly convenient, the self-locking of air spring can not fall so that door is fixed on the maximum position, and manual gag lever post and the folding angle of having saved the traditional approach needs are larger.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is structural representation of the present invention;

Fig. 2 is the schematic diagram of original open-close ways structure;

Fig. 3 is A-A segment structure schematic diagram among Fig. 2;

Among the figure, 1, door lock, 2, handle, 3, door, 4, air spring, 5, collision block, 6, doorframe, 11, original door, 12, hinge, 13, original doorframe, 14, gag lever post, 15, original door lock, 16, positioning seat

The specific embodiment

Structural representation of the present invention such as Fig. 1, a kind of rotary drilling rig cladding element gas spring switching door, comprise door lock 1, handle 2, door 3, air spring 4, collision block 5, doorframe 6, top and doorframe 6 tops of door 3 are hinged, door 3 interludes are provided with air spring 4 with doorframe 6 centres and are connected, door 3 is provided with handle 2, and the end of door 3 is equipped with door lock 1, and collision block 5 is equipped with in doorframe 6 lower ends.

Automatically door 3 is slowly flicked by air spring 4 after opening door lock 1, when stroke reaches maximum, air spring 4 self-lockings also are fixed on eminence with door 3, the folding angle determines by choosing air spring and installation site, on the doorframe 6 air spring install hinge from swivel point more close to, the folding angle is larger, and general angle can reach 135 °.Close door such as need, hold handle 2 and get final product whole moving process light and fast downwards.

The invention enables the folding of covering door to become particularly convenient, the back door of unblanking can be opened automatically up, as long as selected angle is suitable, just can obtain the larger visual field, the self-locking of air spring so that the door be fixed on the maximum position, can not fall, save the manual gag lever post that traditional approach needs, have good use value.

Claims

1. rotary drilling rig cladding element gas spring switching door, comprise door lock (1), handle (2), door (3), air spring (4), collision block (5), doorframe (6), top and doorframe (6) top of door (3) are hinged, it is characterized in that, door (3) interlude is provided with air spring (4) with doorframe (6) centre and is connected, door (3) is provided with handle (2), and the end of door (3) is equipped with door lock (1), and collision block (5) is equipped with in doorframe (6) lower end.
