Abstract
The utility model relates to an A-frame for lifting a drilling rig derrick which is characterized by comprising a pulley wheel seat, a pulley wheel, an A-frame body, a rope blocking device, a first connecting seat and a second connecting seat. The pulley wheel seat is arranged at the top of the A-frame body, the pulley wheel and the rope blocking device are arranged on the pulley wheel seat, and the A-frame body comprises a vertical supporting column and an inclined supporting column. The vertical supporting column is connected with the top end of the inclined supporting column, the first connecting seat is arranged in the middle of the vertical supporting column, and the second connecting seat is arranged at the lower end of the vertical supporting column. Two pin shaft holes are arranged on the second connecting seat. Compared with the prior art, the A-frame for lifting the drilling rig derrick has the advantages that 1 the structure is simple and light, and connection of the A-frame and a drill floor is convenient; and 2 the whole A-frame can be overturned to the position under the drill floor surface, serve as a paving platform support rod, save the space of the drill floor and enlarge working area of the drill floor by being matched with a paving platform.
Description
Technical field
The utility model relates to derrick telescoping device field, particularly a kind of drilling derrick Shears that hoists.
Background technology
It is important link in the oil drilling dead work that drilling derrick hoists.The drilling derrick lifting bracket often is designed to very heavy large-scale support, and installing/dismounting is all inconvenient, can not satisfy the requirement that the dismounting of oil drilling facility is quick, be convenient to move.
Summary of the invention
The purpose of the utility model provides a kind of drilling derrick Shears that hoists, and overcomes the deficiency of prior art, and the Shears body structure is simply light, and is easy to connect with rig floor.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of drilling derrick Shears that hoists; Comprise pulley base, pulley, herringbone support body, ward off rope device, Connection Block one and Connection Block two, herringbone support body top is provided with pulley base, and pulley base is provided with pulley and ward off rope device; Said herringbone support body comprises straight dagger and shore; Straight dagger links to each other with the shore top, and straight dagger middle part is provided with Connection Block one, and straight dagger bottom is provided with Connection Block two.
Said Connection Block two is provided with two pin shaft holes.
Compared with prior art, the beneficial effect of the utility model is: 1) simple and light, and easy to connect with rig floor; 2) whole turning to the rig floor face, can use by pawnshop platform strut bar, save floor space, collocation shop platform can increase the rig floor working area.

Fig. 1 is the utility model example structure scheme drawing;
Fig. 2 be derrick when hoisting the utility model be connected scheme drawing with rig floor;
Fig. 3 is that the utility model was connected scheme drawing with rig floor after derrick hoisted.
Among the figure: the straight dagger 8-of 1-pulley base 2-pulley 3-herringbone support body 4-ward off rope device 5-Connection Block one 6-Connection Block, two 7-shore 9-bearing pin one 10-rig floor 11-bearing pin two 12-bearing pins three 13-bearing pins four 14-pin-and-holes one 15-pin-and-hole two 16-pin-and-holes three
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Seeing Fig. 1, is a kind of drilling derrick of the utility model Shears example structure scheme drawing that hoists, and comprises pulley base 1, pulley 2, herringbone support body 3, ward off rope device 4, Connection Block 1 and Connection Block 26; Herringbone support body 3 tops are provided with pulley base 1; Pulley base 1 is provided with pulley 2 and ward off rope device 4, and herringbone support body 3 comprises straight dagger 7 and shore 8, and straight dagger 7 links to each other with shore 8 tops; Straight dagger 7 middle parts are provided with Connection Block 1, and straight dagger 7 bottoms are provided with Connection Block 26.
Connection Block 26 is provided with pin-and-hole 2 15 and pin-and-hole 3 16.Shore 8 bottoms are provided with pin-and-hole 1.
See Fig. 2, Fig. 3; When derrick hoisted, shore 8 bottoms on the herringbone support body 3 were hinged through bearing pin 1 and rig floor 10, and the Connection Block 26 of straight dagger 7 bottoms is hinged with bearing pin 3 12 and rig floor 10 through bearing pin 2 11; After herringbone support body 3 is fixed on the rig floor; Big lifting rope is through in the pulley 2, and ward off rope device 4 can prevent that big rope from skidding off pulley groove, and herringbone support body 3 can serve as the strong point of derrick telescoping at this moment; After derrick has hoisted, pull down bearing pin 1 and bearing pin 2 11, herringbone support body 3 outwards turn under the rig floor face around bearing pin 3 12, with bearing pin 4 13 with Connection Block 1 and rig floor 10 hinged securement after, will spread platform 14 and be arranged on the herringbone support body 3, can increase the area of rig floor.
