The specific embodiment
Below we do further and elaborate hydraulic lifting derrick of the present utility model with specific embodiment by reference to the accompanying drawings; in the hope of more cheer and bright, understand architectural feature of the present utility model and use procedure, but can not limit protection domain of the present utility model with this.
Please see Figure 2 and Fig. 4, Fig. 2 is the utility model oil-well rig boring tower structural representation while being horizontal.Fig. 4 is the utility model oil-well rig boring tower structural representation when vertical position.As seen from the figure, oil-well rig hydraulic lifting derrick of the present utility model is a kind of innovation design to the oil-well rig boring tower of prior art.Like the prior art, wherein oil-well rig includes derrick 4, base 7, and described derrick is positioned at the top of base, and described base includes drilling floor surface 51 and bottom base 52.
As a new breakthrough design, on the utility model oil-well rig hydraulic lifting derrick, be provided with hydraulic jack 6, strut 7 and tripod 8.
The centre of derrick is provided with a pin otic placode 9 near the position of bottom.When derrick is installed, pin otic placode 9 is connected with hydraulic jack 6 tops.
When derrick 4 is during in level, hydraulic jack 6 is perpendicular to the lower basal plane 52 of derrick 4 and base, and hydraulic jack plays the effect of supporting derrick 4.
The bottom of derrick 4 is provided with round end 41 and fixed end 42, when derrick installation, the round end of derrick 41 is connected by rotating shaft with the tip position of tripod 8.When derrick 4 hoists, derrick 4 rotates around tripod 8, and final derrick 4 rests on vertical position.The fixed end 42 of derrick is connected by rotating shaft with one end of strut 7.At derrick 4, hoist in process, strut 7 moves along with the rising of derrick 4 fixed ends 42.
Drilling floor surface is provided with immobilising device 10, and the other end of described immobilising device 10 and strut 7 is provided with corresponding aperture.When derrick 4 turns to vertical position, strut 7 just rests on immobilising device 10, and the aperture on the aperture on strut 7 and immobilising device 10 overlaps, and by squeezing into pin in aperture, strut 7 is fixed on drilling floor surface 51.
Tripod 8 is fixed on and on the drilling floor surface 51 of base, plays the effect of supporting derrick 4.Being shaped as of tripod 8 "
r" shape, vertical rack 81 is perpendicular to drilling floor surface 51, and tilted supporter 82 tilts to vertical rack direction, and the top of two supports and centre position are fixing by cross bar 83.Wherein vertical rack 81 plays load-bearing effect, and tilted supporter 82 and cross bar 83 play the effect of stablizing vertical rack 81.Vertical rack 81, tilted supporter 82 and cross bar 83 form firm tripod 8 structures.
When derrick 4 is raised to vertical position, derrick 4 and tripod 8 are point-blank and perpendicular to drilling floor surface 51.The active force of 4 pairs of tripods 8 of derrick drops on vertical rack 81, so by vertical rack by force transmission to drilling floor surface 51.
The hydraulic lifting derrick of the utility model oil-well rig carries out the installation of derrick while being horizontal, the round end of derrick 4 41 is connected with the top of tripod 8, the fixed end 42 of derrick 4 is connected with strut 7, and the pin otic placode 9 on derrick is connected with hydraulic jack 6.After derrick installation, primer fluid compressing cylinder 6, derrick 4 starts to hoist.When derrick lifting, along with the promotion of hydraulic jack 6, derrick 4 rotates around tripod 8.When 4, derrick is raised to vertical position, strut 7 is fixed on the immobilising device 10 of drilling floor surface 51 to support derrick 4, derrick 4 enters vertical duty.
Derrick of the present utility model adopts hydraulic jack as the power set that hoist of derrick, derrick lifting speed is fast, this fast lifting derrick adopts tripod simple in structure and strut for supporting, and has reduced the cost of installation and the difficulty of installation of derrick, and has improved the installation effectiveness of derrick.The installation of derrick and the technology that hoists have simply reduced the quantity of executing brill personnel.
