Background technology
In recent years, along with the fast development of water power hydraulic engineering construction cause, overburden cover is increasing, from about 40m to about 100m, about 200m, about 300m, about 400m, even more than 500m, this is challenge again and again to water power hydraulic engineering drilling technique, it requires that water power water conservancy driller author constantly pushes away to deposit and makes new advances, and being ready for the challenge again and again, reaches probing object.Along with the development of explosion pipe-following drilling technology, the sleeve pipe follow-up degree of depth is increasing, and the difficulty of case pulling and recycling is also more and more higher.And the case pulling method generally adopted at present be adopt top on rig to coordinate sash weight is counter to be beaten, it is limited that this method works the degree of depth of pulling out sleeve pipe, is usually no more than 200m, and usually can not rise completely and pull out; The drawbench adopted in prior art, is mainly two cylinder structure, and its pulling force, generally at 60t ~ 80t, rises and pulls out the needs that tubing depth can not meet the complicated covering layer probing of water power hydraulic engineering ultra-deep.In addition, adopt two cylinder structure, rise pull out sleeve pipe time usually because its unbalance stress run-off the straight causes sleeve pipe to pull off, sleeve pipe such as can not to extract completely at the situation; Meanwhile, adopt two oil cylinder will meet enough pulling forces, often need to increase single oil cylinder appearance and size and weight, make troubles to tube drawing operation and relocation equipment.
Utility model content
The technical problem that the utility model solves is to provide one and can improves the case pulling degree of depth, has improved the multi-cylinder synchronous drawbench pulling out stability simultaneously.
The utility model solves the technical scheme that its technical problem adopts: multi-cylinder synchronous drawbench, comprise top board, base plate and hydraulic jack, top board and base plate are respectively arranged with the cased perforated of passing for sleeve pipe, described hydraulic jack is no less than three, described multiple hydraulic jack interval is evenly distributed in the circumference of cased perforated, and the base end of each hydraulic jack and base plate hinged, the push rod end of hydraulic jack and top board hinged.
Further: also comprise Hydraulic Station, the input hydraulic pressure oil circuit of described multiple hydraulic jack and output hydraulic pressure oil circuit in parallel respectively after be communicated with Hydraulic Station.
Further: the base end of each hydraulic jack is connected by hinge with base plate, the push rod end of hydraulic jack and top board pass through hinge.
Further: each hydraulic jack and the connection between base plate and top board are for removably connecting.
Further: the axis of each bearing pin and the axes intersect of sleeve pipe.
Further: above top board, be also provided with slips and slip spider.
Further: described top board and base plate are all in square, and described cased perforated is arranged on above-mentioned foursquare center, and described hydraulic jack has four, four hydraulic jacks respectively with foursquare four right angle one_to_one corresponding.
Further: on top board and base plate, be provided with handle.
The beneficial effects of the utility model are: by adopting Multi-cylinder structure, can improve the case pulling degree of depth on the one hand, can improve drawbench on the other hand and work stability when pulling out; Simultaneously, when ensureing identical pulling force, work appearance and size and the weight of pulling out and can greatly reduce every oil cylinder for machine relative to double-cylinder structure, time like this by each oil cylinder being adopted removably installation, being more convenient to pull out the operation of sleeve pipe and the resettlement of equipment is operated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of hydraulic circuit of the present utility model;
Be labeled as in figure: top board 1, base plate 2, hydraulic jack 3, sleeve pipe 4, base end 31, push rod end 32, Hydraulic Station 5, input hydraulic pressure oil circuit 51, output hydraulic pressure oil circuit 52, bearing pin 6, slips 7, slip spider 8, handle 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in fig. 1, multi-cylinder synchronous drawbench described in the utility model, comprise top board 1, base plate 2 and hydraulic jack 3, top board 1 and base plate 2 are respectively arranged with the cased perforated of passing for sleeve pipe 4, described hydraulic jack 3 is provided with and is no less than three, described multiple hydraulic jack 3 interval is evenly distributed in the circumference of cased perforated, and the base end 31 of each hydraulic jack 3 is hinged with base plate 2, and the push rod end 32 of hydraulic jack 3 is hinged with top board 1.
Wherein, arrange and be no less than three hydraulic jacks 3, the circumference of hydraulic jack 3 along cased perforated is distributed simultaneously, its objective is in order to ensure the stability of drawbench when tube drawing operation.As shown in fig. 1, can preferably by top board 1 and base plate 2 all in square, described cased perforated is arranged on above-mentioned foursquare center, and described hydraulic jack 3 has four, four hydraulic jacks 3 respectively with foursquare four right angle one_to_one corresponding.
In addition, can synchronization job in order to ensure multiple hydraulic jack 3, when arranging Hydraulic Station 5, be communicated with Hydraulic Station 5 after further the input hydraulic pressure oil circuit 51 of multiple hydraulic jack 3 and output hydraulic pressure oil circuit 52 is in parallel respectively; Concrete hydraulic circuit can refer to annexation shown in Fig. 2.
