Description

(54) TELESCOPIC TOWER

one

The invention relates to oil field equipment, namely, telescopic towers.

A known telescopic tower comprising fixed and movable sections, a fixing unit of the latter with spring-loaded stops and cranks interconnected by means of thrusts, and a system for controlling the stops 1.

However, the implementation of the system for removing the stops, the priz.maticheskaya complicates the design of the device and reduces its reliability.

The purpose of the invention is to simplify the design and increase the reliability of the device.

This goal is achieved by the fact that the stop control system is made in the form of a spring-loaded rocker arm that is hinged on a fixed section, one shoulder of which is provided with a roller, and the other with a flexible link connected to the crank, and a copier mounted on the movable section with the ability to adjust its position along the axis of the mast and the interaction with the roller, and the working surface

the feast is made along the length of the paniioii: -, lifting the movable section.

FIG. 1 pr.stavleno irel.chagoye device, general view; on f11G. 2 mast part, node t in FIG. one; on iJMi ;. 3 is a section .A-A in FIG. 2; on flash 4 p.a.mchch B - B in FIG. 2

Claims (1)

Telescopic tower contains iolvidnuyu 1 and fixed 2 sections of the bottom of the node in the working position, located symmetrically on both sides of the mast. Ka / cd151 | 1 fixation unit of the movable section spring-loaded with a buckle 3 folding supports 4 and 5, bodies b, strips 7. bolts 8 and 9, curved types 10 and II, connected between themselves 12 to a fork and 1 13 and 14, and systems 15 for controlling the stops, in the form of a fixedly mounted on a stationary section 2 of a spring loaded rocker arm 16 and 15, one shoulder of which is provided with a roller 17, and the other connected with a flexible link 18 with a crank 10, and a copier 19 mounted on the fixed section 1 with the possibility of adjusting its position in height and interaction of its working surface 20 s roller 17 koromys.cha 16. D. | ina working surface 20 of the copier 19 is made equal to the length of the lifting of the movable section I. The device works as follows: v .i VI. In TpaiienopftioM and younger, i. when folded, the stops 4 and 5 are held by section 1 in their housings 6. When section 1 extends, the spring 3 through bar 12 and the core 10 and 11 converts the ports 4 and 5 to the working position and the section l is fixed to the stops. For dismantling: Ms. section 1 is raised to the position when the copier 19 is above the roller 17 of the rocker arm 16, and then it is pulled out, with the beam 16, deflected rifle 19, through a flexible link 18, cranks 10 and 11 and tu 2 turns the stops 4 and 5 in the housing 6 and seci 1 passes down. Thus, the operation of the proposed device is ensured only by mechanical references, which simplifies its construction and increases reliability. Claims of the invention: A telescopic peak, including fixed and movable sections, a fixing unit for the latter with spring-loaded stops and cranks interconnected, and an unravlepi unor.mi system. characterized in that, in order to simplify the construction and increase the case, the stop control system is made in an airbag mounted hingedly on a fixed section of an attached rocker arm, one shoulder of which is provided with a roller and the other with a flexible link connected to the crank and a copier mounted on the movable sections with the possibility of adjusting its position along the axis of the mast and the interaction with the roller, and the working surface of the copier is made at a length equal to the height and elevation of the movable section.
