Description

A special cat ladder for well site maintenance operation

Technical Field

The utility model relates to a ladder with longitudinal fixity part specifically is a special cat ladder that is used for well site maintenance operation.

Background

The staff overhauls the operation, and the purpose is that the inspection appears functional defect's spare part because of long-time work, maintains and changes, to workover rig and these higher equipment of beam-pumping unit, the staff generally can carry the ladder when overhauing the operation.

Most workover rigs and pumping units have crawling ladders which are welded on the machine body, and workers can replace a plurality of important components after climbing by using the crawling ladders, but some old machine types do not have the crawling ladders, and particularly when parts near a walking beam of the walking beam pumping unit are maintained, the workers even need to tie safety belts to perform high-altitude operation.

Because of the peculiar characteristics of well site ground, the earthwork of the bottom of the pumping unit is often softer, the ground of part well sites is uneven, a ladder carried by a worker needs to be manually supported by other workers when the scaffold is used, and the scaffold spliced by using steel pipes is large in size and large in occupied area, and is not suitable for the workers to overhaul and use.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a special cat ladder for well site maintenance operation fixes the cat ladder on the well site through the simple operation of staff, reaches the purpose that improves maintenance operation security.

The technical scheme is as follows: the utility model provides a special cat ladder for well site maintenance operation, includes two identical landing legs and a plurality of foot bars of fixed setting on the landing leg, characterized by: the lower end face of one of the supporting legs is welded with a strip-shaped plate, the lower end face of the other supporting leg is welded with an annular plate, the upper surface of the annular plate is welded with a sliding sleeve with the same aperture as the annular plate, and the upper end face of the sliding sleeve is welded with an annular baffle with the same aperture as the sliding sleeve; the inside activity of sliding sleeve sets up thick pole, the lower part of thick pole sets up the cone, the upper portion welding of thick pole with ring baffle has the clamp plate of equal diameter, square piece is welded to the higher authority of clamp plate.

Furthermore, a thin rod is welded below the strip-shaped plate, and a conical head is arranged at the lower part of the thin rod.

Further, the lower face of the annular plate and the lower face of the strip-shaped plate are located on the same horizontal plane.

Further, the thin rod is a pair of identical thin rods arranged below the strip-shaped plate.

Has the advantages that: the utility model discloses a through the simple operation of staff, can fix the cat ladder on the well site, current activity ladder is more firm relatively, can reach the purpose that improves staff's security, this utility model simple structure moreover, the cost of manufacture is low.

1. a conical head; 2. a thick rod; 3. an annular plate; 4. a sliding sleeve; 5. an annular baffle; 6. pressing a plate; 7. a square block; 8. a support leg; 9. a foot bar; 10. a strip plate; 11. a thin rod.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the accompanying fig. 1 to 2, but the invention can be implemented in many different ways as defined and covered by the claims.

It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed, unless otherwise specified, and all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

Referring to the attached

drawings

1 and 2, the special crawling ladder for well site overhaul operation provided by the utility model comprises two identical support legs 8 and a plurality of foot levers 9 fixedly arranged on the support legs 8, wherein a strip-shaped plate 10 is welded on the lower end face of one support leg 8, an annular plate 3 is welded on the lower end face of the other support leg 8, a sliding sleeve 4 with the same aperture is welded on the annular plate 3, and an annular baffle 5 with the same aperture is welded on the upper end face of the sliding sleeve 4; thick pole 2 is set up in the inside activity of sliding sleeve 4, the lower part of thick pole 2 sets up cone 1, the upper portion welding of thick pole 2 with ring baffle 5 has the clamp plate 6 of equal diameter, square piece 7 of the higher authority welding of clamp plate 6.

In order to make this utility model reach better fixed effect, the slender pole 11 of welding below the strip shaped plate 10, the lower part of slender pole 11 sets up cone 1.

In order to make the utility model achieve better fixing effect, the lower surface of the annular plate 3 and the lower surface of the strip-shaped plate 10 are positioned on the same horizontal plane.

In order to achieve a better fixing effect of the utility model, the thin rod 11 is a pair of identical thin rods 11 arranged below the strip-shaped plate 10.

In the concrete operation process, the staff uses instruments such as sledgehammer to hit and hits square piece 7 and can fix this utility model on the well site, thick pole 2 and thin pole 11 can restrict this utility model longitudinal movement, annular slab 3 and bar shaped plate 10 can restrict this utility model and swing to both sides, can say that, this utility model is that two thin poles 11 below using bar shaped plate 10 fix this utility model with thick pole 2 jointly, the three forms firm triangle-shaped structure, in operation process, though still need other staff's auxiliary operation, but the activity cat ladder that has relatively had higher security.

In addition, the utility model discloses a still have simple structure, advantage that the cost of manufacture is low to saving manufacturing cost, improving the economic benefits of unit and having positive effect.
