Description
Technical field
This utility model relates to drilling equipment, is specifically related to a kind of built-in crawler belt levelling gear for drill carriage.
Background technology
Existing drill carriage crawler belt levelling gear typically uses leveling cyclinder and external control valve block structure, oil cylinder
And it is connected by hydraulic hose between external control valve block, the drill carriage crawler belt levelling gear of this structure, knot
Structure is the compactest, and control valve block and leveling cyclinder need maintaining respectively, very inconvenient.The more important thing is
Owing to the hydraulic hose between oil cylinder and external control valve block once occurs accident (booster or disconnected by pounding), drill carriage
Will tumble and cause serious equipment and personal safety accident.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, it is provided that a kind of compact conformation built-in
Formula drill carriage crawler belt levelling gear.
In order to realize object above, this utility model have employed techniques below scheme:
A kind of built-in drill carriage crawler belt levelling gear, including cylinder body and piston rod, described cylinder body one end is provided with oil
Cylinder hydraulic fluid port, cylinder interior includes big chamber and the loculus separated by piston rod, in big chamber, loculus and oil cylinder oil
Be provided with hydraulic control unit between Kou, hydraulic fluid port A that described hydraulic control unit includes being arranged on cylinder body, hydraulic fluid port B, hydraulic fluid port P,
Hydraulic fluid port T and be arranged on hydraulic cartridge valve and the overflow valve of cylinder interior, described hydraulic fluid port A inserts through a hydraulic pressure
Dress valve connects with the big chamber in cylinder body, and hydraulic fluid port B connects with the loculus in cylinder body through a hydraulic cartridge valve,
Hydraulic fluid port P and two hydraulic cartridge valves connect, and each hydraulic cartridge valve is connected with an overflow valve respectively, two
Overflow valve is connected with hydraulic fluid port T.
When hydraulic fluid port P has pressure signal, hydraulic cartridge valve is opened；When hydraulic fluid port P no pressure signal, hydraulic pressure
Inserted valve disconnects.
Hydraulic fluid port P is signal hydraulic fluid port, and when hydraulic fluid port P has pressure signal, 2/2-way hydraulic cartridge valve is opened,
Oil circuit is unimpeded, connects between hydraulic fluid port A, hydraulic fluid port B and the large and small chamber in cylinder body.Hydraulic oil is squeezed into toward hydraulic fluid port A
Time, the piston rod in cylinder body stretches out；Otherwise, when past hydraulic fluid port B squeezes into hydraulic oil, piston rod bounces back；Work as oil
When the hydraulic fluid pressure of mouthful A or hydraulic fluid port B exceedes the setting value of overflow valve, hydraulic oil from this overflow valve off-load,
Hydraulic fluid port T oil return.When hydraulic fluid port P no pressure signal, hydraulic cartridge valve disconnects, hydraulic fluid port A, hydraulic fluid port B and cylinder body
Block between interior large and small chamber.Playing hydraulic oil toward hydraulic fluid port A, B cannot drive hydraulic jack to move, from
And realize the locking of hydraulic jack.
The built-in drill carriage crawler belt levelling gear of said structure, will by arranging hydraulic control unit on leveling cyclinder
External hydraulic control valve block is integrated into inside leveling cyclinder, makes levelling gear structure compacter, and it is right to facilitate
The care and maintenance of control valve block.Also eliminate oil pipe accident booster simultaneously or pounded disconnected and cause equipment and people
The hidden danger of body accident, it is ensured that drill carriage and the work safety of personnel.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is hydraulic schematic diagram of the present utility model.
Wherein: 1, cylinder body, 11, big chamber, 12, loculus, 2, hydraulic fluid port A, 3, hydraulic fluid port B, 4, hydraulic fluid port P,
5, hydraulic fluid port T, 6, hydraulic cartridge valve, 7, overflow valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
One built-in drill carriage crawler belt levelling gear as depicted in figs. 1 and 2, including cylinder body 1 and piston rod,
Cylinder body one end is provided with oil cylinder port, internal big chamber 11 and the loculus 12 including being separated by piston rod of cylinder body 1,
Being provided with hydraulic control unit between big chamber 11, loculus 12 and oil cylinder port, described hydraulic control unit includes being arranged on cylinder body
Hydraulic fluid port A2 on 1, hydraulic fluid port B3, hydraulic fluid port P4, hydraulic fluid port T5 and be arranged on the hydraulic cartridge valve 6 of cylinder interior
With overflow valve 7, the hydraulic cartridge valve 6 of the present embodiment is 2/2-way inserted valve.Hydraulic fluid port A2 is through a liquid
Pressure inserted valve 6 connects with the big chamber 11 in cylinder body, and hydraulic fluid port B3 is in a hydraulic cartridge valve 6 with cylinder body
Loculus 12 connect, hydraulic fluid port P4 and two hydraulic cartridge valves 6 connect, each hydraulic cartridge valve 6 respectively with
One overflow valve 7 connects, and two overflow valves 7 are connected with hydraulic fluid port T5.Hydraulic fluid port A2, hydraulic fluid port B3, hydraulic fluid port P4,
Hydraulic fluid port T5 connects the oil pipe of outside respectively, and wherein hydraulic fluid port P4 is signal hydraulic fluid port, and hydraulic fluid port T5 is that oil return opening is when oil
When mouth P4 has pressure signal, hydraulic cartridge valve 6 is opened, and oil circuit is unimpeded, hydraulic fluid port A2, hydraulic fluid port B3 and cylinder body
In big chamber 11, connect between loculus 12.When past hydraulic fluid port A2 squeezes into hydraulic oil, the piston rod in cylinder body is stretched
Go out；Otherwise, when past hydraulic fluid port B3 squeezes into hydraulic oil, piston rod bounces back；When hydraulic fluid port A2 or the hydraulic pressure of hydraulic fluid port B3
When oil pressure exceedes the setting value of overflow valve 7, hydraulic oil is from this overflow valve 7 off-load, hydraulic fluid port T5 oil return.When
During hydraulic fluid port P4 no pressure signal, hydraulic cartridge valve 6 disconnects, hydraulic fluid port A2, hydraulic fluid port B3 and the big chamber in cylinder body
11, block between loculus 12.Playing hydraulic oil toward hydraulic fluid port A2, hydraulic fluid port B3 is to drive hydraulic jack to move
, thus realize the locking of hydraulic jack.
External hydraulic control device is integrated in leveling cyclinder by this utility model, compact conformation, it is simple to after
Maintenance and management in continuous use.
