Abstract
The utility model relates to a lifting rope device for a racking platform, which comprises a lifting rope and pulleys. A pulley A is arranged at the upper end of the lower body of a head frame, a pulley B is arranged at the lower end of the upper body of the head frame, a pulley C is arranged on a traveling hoist, and the lifting rope has one end thereof fixed on the racking platform and the other end thereof sequentially passing through the pulley C, pulley B and pulley A and fixed on the lower body of the head frame. The device, with a simple structure, increases the winding stroke of a wire rope, ensures the head frame to keep in a tightening state all the time during movement, and prevents the racking platform from tamping and pressing the upright post of the head frame.
Description
Technical field
The utility model relates to a kind of oil drilling equipment, particularly relates to a kind of quadruple board platform lifting rope device.
Background technology
Self-propelled workover rig is in the process of carrying out well workover, hoisting and transferring of derrick needs quadruple board platform to open thereupon and to pack up, design in the past can not realize finishing synchronously, and the quadruple board platform lifting rope can not guarantee tight state, has caused quadruple board platform that the phenomenon of pounding kill-job frame column is arranged in the withdrawal process.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of reasonable in design is provided, easy to operate quadruple board platform lifting rope device.
In order to address the above problem, the utility model by the following technical solutions:
A kind of quadruple board platform lifting rope device comprises lifting rope and pulley, and pulley A is installed in derrick lower body upper end, pulley B is installed in lower end, derrick upper body, pulley C is installed on the overhead traveling crane, and lifting rope one end is fixed on the quadruple board platform, and an end is according to this by pulley C, pulley B and pulley A and be fixed on the derrick lower body.
Compared with prior art, the beneficial effects of the utility model are:
This device has increased pulley on the derrick lower body on original architecture basics, thereby increased the stroke that whole lifting rope twines, and guarantees that lifting rope remains tight state, the phenomenon of having avoided quadruple board platform to pound kill-job frame column in the withdrawal process in the derrick course of action.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, derrick upper body 2, derrick lower body 3, pulley A 4, pulley C 5, pulley B 6, quadruple board platform
The specific embodiment
A kind of quadruple board platform lifting rope device, as shown in Figure 1, comprise lifting rope and pulley, pulley A3 is installed in derrick lower body 2 upper ends, pulley B5 is installed in 1 lower end, derrick upper body, pulley C4 is installed on the overhead traveling crane, and lifting rope one end is fixed on the quadruple board platform 6, and an end is successively by pulley C4, pulley B5 and pulley A3 and be fixed on the derrick lower body 2.
When original derrick reclaims, downward movement along with derrick upper body 1, quadruple board platform 6 is rotated to vertical direction by level, because derrick lower body 2 limited length, wire rope is long quadruple board platform 6 will to be occurred to regain action not to be the situation of vertical state after finishing, when derrick when vertical state is transferred to level, quadruple board platform 6 has a process that hurtles down, the situation that has so just caused quadruple board platform 6 to pound kill-job frame column.
Claims (1)
1. quadruple board platform lifting rope device, comprise lifting rope and pulley, it is characterized in that, pulley A is installed in derrick lower body upper end, pulley B is installed in lower end, derrick upper body, pulley C is installed on the overhead traveling crane, and lifting rope one end is fixed on the quadruple board platform, and an end is successively by pulley C, pulley B and pulley A and be fixed on the derrick lower body.
