As shown in Figs 1-4, a kind of carbon dioxide fracturing device is with only flying device, including base assembly, strut socket 1, link assembly,
Slide assemblies, center-pole 6 and clamping sleeve 7.The center-pole 6 extends to after sequentially passing through the base assembly and strut socket 1
In the slide assemblies；The slide assemblies are located in the hollow cavity of the base assembly；The strut socket 1 rises by second
Pin 12 is fixedly mounted on the periphery of the base assembly lower end, and in this embodiment, the second size for rising by pin 12 is φ 16
×60；The link assembly is respectively hinged on the strut socket 1 and slide assemblies, that is, is located at existing Vacancy between the two
It sets.The clamping sleeve 7 is threaded in the upper end of the base assembly；The clamping sleeve 7, which moves down, pushes the sliding
Component is moved down along center-pole 6, so that the link assembly be driven to be against on the inner wall of borehole, is improved in link assembly and borehole
Frictional force between wall.
The base assembly includes pedestal 4, outer cylinder 10 and top link 14.Wherein, the bottom thread of the pedestal 4 connects
It is connected to fracturing device 15, passes through holding screw 13 in the centre bore of the pedestal 4 and is fixedly installed with the center-pole 6, holding screw
13 specification size is M6 × 20, holding screw 13 can either guarantee that center-pole 6 and pedestal 4 are fixedly mounted, and can be guaranteed
Core bar 6 will not rotate.The lower end of the outer cylinder 10 passes through on the step surface for being welded and fixed and being mounted on 4 top of pedestal, guarantees
The stability connected between outer cylinder 10 and pedestal 4.The upper end of the outer cylinder 10 is embedded in and is fixedly mounted on the top link
14 bottom end is provided with threaded line on the inner hole of top link 14, and the clamping sleeve 7 is threaded in the top link
In 14 inner holes, and can the screw on top link 14, realize clamping sleeve 7 relative to moving down on top link 14
It is dynamic.In addition,
The slide assemblies include sliding seat 5 and inner cylinder 9.Wherein, the bottom end of the inner cylinder 9, which is embedded in and passes through, is welded and fixed
It is mounted on the top stage face of the sliding seat 5；The sliding seat 5 and inner cylinder 9 are sleeved on the center-pole 6, can be along
Center-pole 6 slides up and down.The lateral surface of the sliding seat 5 is matched with the centre bore of the pedestal 4, and sliding connects each other
Touching.The top of the inner cylinder 9 passes through the clamping sleeve 7 and is threaded with nut 8,8 model M40 × 2 of nut.In addition, institute
It stating 7 lower end of clamping sleeve and positioning table 9-1 is installed, the positioning table 9-1 welds together with the inner cylinder 9, and clamping sleeve 7 moves down,
Positioning table 9-1 is driven to move down, so that inner cylinder 9 moves down therewith.
The link assembly includes strut 2 and connecting rod 3.Wherein, the upper end of the strut 2 and the lower end of the connecting rod 3 are logical
It is hinged to cross first pin 11 that rises, in this embodiment, the first size for rising by pin 11 is φ 8 × 38.The lower end of the strut 2
It is hinged on the strut socket 1, the upper end of the connecting rod 3 is hinged on the sliding seat 5, on the strut socket 1 and sliding seat 5
It offers hinged used groove, has the spherical type head matched with groove on the end of strut 2 and connecting rod 3, it can be in groove
Interior random rotation, and without departing from the constraint of groove.
