Detailed description of the invention

This utility model embodiment discloses a kind of drilling machine mast, to avoid its exposed structure to be attacked by dust storm.

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

Refer to the main TV structure schematic diagram of a kind of detailed description of the invention of drilling machine mast that Fig. 1-Fig. 4, Fig. 1 provide for this utility model; Fig. 2 is the plan structure schematic diagram of Fig. 1; Fig. 3 is Section A-A structural representation in Fig. 1; Fig. 4 is section B-B structural representation in Fig. 2.

In a kind of detailed description of the invention, the drilling machine mast that this utility model provides includes mast principal piece 1, mast top section 2, mast rear 3 and protective cover 4.

Wherein, mast top section 2 and mast rear 3 lay respectively at the two ends of mast principal piece 1, are provided with fixed pulley, movable pulley and chain in mast. General fixed pulley is arranged at mast top section 2 with in mast rear 3, and movable pulley arranges and in mast principal piece 1, is connected to chain between movable pulley and fixed pulley. Its concrete connected mode and set-up mode refer to prior art, repeat no more herein.

Protective cover 4 is arranged at outside mast, and dismountable with mast fixing is connected. The shape of concrete protective cover 4 and structure can be configured according to the shape of mast and structure, generally may be configured as identical with the shape of mast, and then can be sheathed on outside mast. And between protective cover 4 and mast outer wall, leave a fixed gap, it is simple to the parts normal operation outside mast.

During the drilling machine mast that application this utility model provides, drilling machine mast is provided with unit head and feeds the parts such as oil cylinder. Feeding oil cylinder reciprocating and pull two chains by movable pulley and fixed pulley, chain active force is passed to the unit head being fixed on two chains, unit head moves up and down along mast slide rail, it is achieved feeds and promotes. Setting by protective cover 4, the structures such as original chain being exposed to outside mast are covered, it is to avoid its directly corroding by adverse circumstances such as dusts storm such that it is able to the service life of each parts of effective prolongation, and then the service life of prolongation drilling machine mast, improve the security reliability of its work. Meanwhile, protective cover 4 is dismountable with mast fixing to be connected, and when protective cover 4 is declined by environmental attack protective action, it is simple to only protective cover 4 is replaced, and then saves cost.

Concrete, protective cover 4 can be arranged at outside mast principal piece 1, and mast top section 2 and mast rear 3 outward and are not provided with protective cover 4. Parts owing to being subject to dust storm invasion and attack are predominantly located at outside mast principal piece 1, therefore only arrange protective cover 4 outside mast principal piece 1 and can play effective protective action and the simple in construction of mast principal piece 1, are easy to setting and the installation of protective cover 4 accordingly.

Further, protective cover 4 can with mast principal piece 1 clamping, and the connected mode of clamping is reliable and is easily installed and dismantles. Certainly, as required it is also contemplated that adopt dismountable connected mode of other routines to connect, such as bolt connection etc.

For ease of the installation of protective cover 4 and do not affect the normal operation of mast principal piece 1 external part, on protective cover 4 opening can be axially set along mast, namely protective cover 4 is overall in shelly, the two ends up and down of opening, namely it is parallel to the axial two ends up and down of mast to be tightly connected with mast, and then can effectively prevent the erosion of dust storm.

Concrete, it is possible to protective cover 4 to be set to the axially hinged two parts at described mast, and the jointed shaft between two parts is parallel with the bearing of mast, so can easily and protective cover 4 carry out installing and dismantling.

On the basis of the various embodiments described above, it is possible to scale 5 and then the position that convenient control chain-driving unit head moves are set outside protective cover 4.

Further, cushion pad can be set between protective cover 4 and mast. It is pointed out that the setting of cushion pad should not affect the normal operation of the parts outside mast, therefore position is set should the avoiding each parts of cushion pad. By the setting of cushion pad, it is possible to when preventing protective cover 4 by invasion and attack such as strong wind, mast is caused damage.

Further, it is possible to include multiple cushion pad, and multiple cushion pad be uniformly arranged along the periphery of mast central authorities. And then cushioning effect can be played uniformly all directions of periphery.

Specifically, cushion pad is rubber blanket or the complex buffering pad of foam-rubber cushion or rubber blanket and foam-rubber cushion formation. For complex buffering pad, both can be the complex buffering pad of rubber blanket and the foam-rubber cushion set gradually from the inside to the outside, it is also possible to be the complex buffering pad of rubber blanket and foam-rubber cushion from outside to inside successively. Certainly, as required, it would however also be possible to employ the cushion pad of other materials, only need to ensure buffering effect.

Based on the drilling machine mast provided in above-described embodiment, this utility model additionally provides a kind of rig, and this rig includes any one drilling machine mast in above-described embodiment. The drilling machine mast in above-described embodiment is have employed, so the beneficial effect of this rig refer to above-described embodiment due to this rig.

In this specification, each embodiment adopts the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually referring to.

Above check-valves provided by the utility model is described in detail. Principle of the present utility model and embodiment are set forth by specific case used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof. Should be understood that; for those skilled in the art; under the premise without departing from this utility model principle, it is also possible to this utility model carries out some improvement and modification, these improve and modification also falls in this utility model scope of the claims.
