Abstract
The utility model discloses a hydraulic clamping device which is composed of at least two hydraulic clamping units. Each hydraulic clamping unit comprises a fixed base and an arc-shaped clamping ring, a hydraulic oil cylinder is arranged in each fixed base, the telescopic ends of the hydraulic oil cylinders are connected with the arc-shaped clamping rings, the arc-shaped clamping rings are provided with position clamping structures, and the fixed bases are made of aluminum alloy and are of a square structure in shape. Due to the fact that fixation of a drilling tool in a well is operated by a person, a U-shaped bolt is prone to rotating or falling off, safety accidents are prone to occurring, and a drill is prone to being damaged. The hydraulic clamping device is fixed onto a well drilling rotary plate, when a drilling rod is prepared to be replaced, the telescopic ends of the hydraulic oil cylinders are driven by pistons to stretch out forwards, the drilling rod is tightly clamped by the arc-shaped clamping rings at the positions of the telescopic ends so as to prevent the drilling rod from falling, the position clamping structures on the arc-shaped clamping rings are attached to the step surface of the drilling rod so as to obtain a better anti-slip effect, and therefore well drilling operation can be completed more efficiently and more safely during construction.
Description
Technical field
The utility model relates to mechanical manufacturing field, specifically refers to a kind of hydraulic pressure clamping close device.
Background technology
Along with the fast development of China's agriculture and forestry, be different from traditional hand labour mode, the mechanization degree of modern agriculture is more and more higher.As excavated the well for irrigating or drinking, abandon original hand digging and used machinery instead, realized mechanically substituting manually, operating efficiency significantly improves.
With regard to current taked machinery well-digging mode, there are in practice many drawbacks.Take towed well sinker as example, mainly comprise pedestal, diesel engine, gearbox, slush pump, hydraulic system, mast and drilling tool etc.The most time-consuming in operating process is the replacing of drilling tool, and general replacing is all to adopt U-shaped bolt made of iron that the depression draw-in groove of the drilling rod tail end in well that submerges is fixed, more manually changes drilling tool.The length of drilling tool is commonly 1.5-2.0m, so the frequency of changing is higher, causes very large inconvenience.And, due to the drilling tool in well is fixed, be manual operation, U-shaped bolt is easy to rotation or comes off, and easily causes the damage of security incident and drill bit.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic pressure clamping close device, the problem of drilling rod (comprising drill bit) in safe and effective fixedly well when solving current middle-size and small-size well sinker more renewing drilling tool in practical operation, reaches the object of efficiency standard safety operation well-digging equipment.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hydraulic pressure clamping close device, comprise at least two hydraulic pressure engaging unit, described hydraulic pressure engaging unit comprises holder and arc snap ring, is provided with a hydraulic jack in described holder, the telescopic end of hydraulic jack is connected with arc snap ring, and described arc snap ring is provided with retaining structure.When stopping drilling well preparation replacing drilling rod, in hydraulic jack, piston rod drives the arc snap ring at its telescopic end place to move forward, by the drilling rod clamping having stopped operating; When arc snap ring contacts with drilling rod, the step surface of retaining structure and drilling rod fits, and is carved with multiple tracks anti-slip tank on retaining structure, prevents rocking of drilling rod, the new drilling rod of handled easily personnel quick-replaceable.
Further, described holder material is aluminium alloys, and quality is gently easy to carry and changes.
Further, described its material of arc snap ring is alloy steel, has the feature of shock-resistant, anticorrosion, long service life.
Further, the upper plane of described retaining structure is provided with anti-slip tank, increases the step surface of drilling rod and the friction between retaining structure, prevents that drilling rod from skidding.
Further, described arc snap ring for being fixedly connected with or removably connecting, is convenient to detachable maintaining with retaining structure.
The utility model can be provided with three hydraulic pressure engaging unit, and three hydraulic pressure engaging unit are one group, are fixedly centered around around drilling rotary table endoporus.
The utility model compared with prior art, has following advantage and beneficial effect:
A kind of hydraulic pressure clamping close device of 1 the utility model, is fixed on drilling rotary table, and the square structure that holder is aluminum alloy material, can install easily or dismantle; When preparing to change drilling rod, the telescopic end of hydraulic jack stretches out forward under the drive of piston, and the arc snap ring at telescopic end place clamps drilling rod, and snap ring material is alloy steel, can effectively prevent from making snap ring fracture because of the impact force that drilling rod falls.
Retaining structure on 2 arc snap rings and the laminating of the step surface of drilling rod, and on retaining structure, plane is provided with anti-slip tank to obtain better skidproof effect, thus in construction, complete more efficiently and safely well-digging operation.

Fig. 1 is the utility model structure chart;
Fig. 2 is the top view of arc snap ring;
Fig. 3 is the left view of arc snap ring;
Fig. 4 is jackrod structure figure.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment 1
As Fig. 1,2,3,4, the hydraulic pressure clamping close device in the utility model, its hydraulic pressure engaging unit comprises holder 1, screwed hole 2, hydraulic jack 3, arc snap ring 4.Holder 1 is fixed on drilling rotary table through screwed hole 2, hydraulic jack 3 and holder 1 phase embedding, and arc snap ring 4 is connected with the telescopic end of hydraulic jack 3.
When stopping drilling well preparation replacing drilling rod, in hydraulic jack 3, piston rod drives the arc snap ring 4 at its telescopic end place to move forward, by the drilling rod having stopped operating 6 clampings.When arc snap ring 4 contacts with drilling rod 6, retaining structure 5 fits with the step surface 7 of drilling rod 6, is carved with multiple tracks anti-slip tank on retaining structure 5, prevents rocking of drilling rod 6, the new drilling rod of handled easily personnel quick-replaceable.
Embodiment 2
As shown in Figure 1, the present embodiment is only provided with two hydraulic pressure engaging unit, and two hydraulic pressure engaging unit are one group, are fixedly placed in drilling rotary table endoporus symmetrical.
Embodiment 3
As shown in Figure 2, the upper plane of the retaining structure of the present embodiment is not to be provided with anti-slip tank, but the reeding arranging increases the step surface of drilling rod and the friction between retaining structure, prevents that drilling rod from skidding.
In sum, can realize better the utility model.
