Problems solved by technology

Now provide a mobile operating device that is convenient for the operation of the Christmas tree. The sliding device used can slide up and down in the cuboid groove, and is fixed by a block set in the through hole, so that it can be moved when not in use. Sliding up and fixed, relying on the supporting structure of the work ladder to place it, which solves the technical problem that the work ladder slides arbitrarily during the placement process and is not easy to slide during use

Embodiment 1

[0023] Such as figure 1 , figure 2 As shown, a mobile operating device that facilitates the operation of the Christmas tree includes a working ladder body 1, and the working ladder body 1 includes a first long pole 11 and a second long pole 12 arranged parallel to each other. The first long pole 11, the second long pole One end of long bar 12 is all provided with sliding device, and sliding device comprises connecting cross bar 3, connecting longitudinal bar 4, pulley 5, and one end of connecting longitudinal bar 4 is hinged with connecting cross bar 3, and the other end of connecting longitudinal bar 4 is connected with pulley. The side of the end of the first long rod 11 close to the ground is provided with a cuboid groove 2, and at least two through holes 21 are arranged in the cuboid groove 2, and a detachable block is installed in the through hole 21.

[0024] The existing working ladder structure is provided with a roller structure at the bottom, which can slide the wo...

Embodiment 2

[0026] This embodiment is further defined on the basis of the above embodiments, the sliding device is located on the outer surface of the end of the first long rod 11 that contacts the ground. A sliding device is also provided on the outer surface of the end of the second long rod 12 that contacts the ground. Both outer surfaces of the first long rod 11 and the second long rod 12 are provided with sliding devices to facilitate sliding.

Embodiment 3

[0028] In this embodiment, on the basis of the above embodiments, the cross-section of the connecting cross bar 3 is further defined as a square, and its side width is smaller than the short side width of the cuboid groove 2, with a difference of 1.5-3 cm. There is a certain gap between the connecting cross bar and the cuboid groove, rather than complete close contact, which is beneficial for the connecting cross bar to slide in the cuboid groove.

Abstract

The invention discloses a mobile operation ladder capable of facilitating Christmas tree operation. The mobile operation ladder comprises an operation ladder body, wherein the operation ladder body comprises a first long rod and a second long rod which are arranged parallelly; a sliding device is arranged at one end of the first long rod; the sliding device comprises a connecting cross rod, a connecting longitudinal rod and a pulley wheel; one end of the connecting longitudinal rod is hinged with the connecting cross rod while the other end of the connecting longitudinal rod is connected with the pulley wheel; a cuboid groove is formed in a side wall at one end, which is close to the ground, of the first long rod; at least two through holes are formed in the cuboid groove; clamping blocks capable of being pulled are arranged in the through holes. The pulley wheel device, the cuboid groove and the through holes are arranged on the mobile operation ladder, the connecting cross rod slides up and down in the cuboid groove and the clamping blocks are inserted into the through holes for fixing the position of the connecting cross rod, so that the fixing of the state that the pulley wheel is in contact with the ground is realized and the operation is convenient and simple. The mobile operation ladder has a simple structure, is beneficial to control and can be used for effectively solving the problem of moving around the operation ladder.

Description

technical field [0001] The invention relates to petroleum mechanical equipment, in particular to a mobile operation device which facilitates the operation of a Christmas tree. Background technique [0002] In the process of oilfield development, Christmas trees are widely used. The height of the wellhead of the Christmas tree is generally 1.5-2m from the ground. The staff often need to work on the wellhead of the Christmas tree. Extremely inconvenient. [0003] The Christmas tree is a wellhead device used for oil extraction such as self-flowing wells and mechanical production wells. It is the main equipment for controlling and regulating oil and gas production at the uppermost part of the oil and gas well. It mainly consists of three parts: casing head, tubing head, and Christmas tree body. [0004] The oilfield development staff needs to use the operation ladder during the control operation of the Christmas tree, and there will be multiple Christmas trees in the same oil f...
