Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment in the utility model can make up mutually.
At the technical problem that exists in the prior art, the utility model proposes a kind of fixing device and be provided with the middle mast of this fixing device, to solve following technical problem: 1) wire rope is fixed on the problem that it seems not at random that where could make; 2) problem how to avoid wire rope fixing device and power head device to interfere; 3) how to design the structure of wire rope fixing device in limited space; 4) how wire rope fixing device tightens the problem of wire rope.
Below in conjunction with accompanying drawing, each preferred embodiment of the present utility model is described further:
Please refer to Fig. 1 to Fig. 2, it shows the fixing device of present embodiment, and this fixing device comprises: fixing chuck plate 1 and connected element.Wherein, fixing chuck plate 1 offers for limited impression 12, and offers for the attachment hole 11 that connects in a side of described limited impression 12.Connected element is arranged in described attachment hole 11, is used for fixing described fixing chuck plate 1.
In the present embodiment, this fixing device can be used for the location of parts such as wire rope or fixing, snaps in or easy to operate and fixing reliable when taking out wire rope.And, simple in structure, the easy accessibility of this fixing device.
In an optional embodiment, as shown in Figure 3 and Figure 4, described connected element can comprise bolt 14.In the present embodiment, described attachment hole 11 is bolt hole.Preferably, described connected element also comprises the packing ring that is used with bolt.
In a preferred embodiment, as shown in Figure 2, described fixing chuck plate 1 offers draw-in groove 13 in the outside that offers described attachment hole 11.For example: as shown in Figure 4, draw-in groove 13 is used for being connected in the stiffening rib 21 of middle mast.
It is pointed out that in above-described embodiment that fixing chuck plate 1 is fixed on the stiffening rib 21 by bolt 14, can take full advantage of the space between the front panel (or the side plate that is connected with front panel) of stiffening rib and middle mast, and can fix wire rope effectively.
Preferably, in above-described embodiment, described limited impression 12 is semicircle.In the present embodiment, adopt semicircular structure, be convenient to ccontaining wire rope.
On the other hand, the utility model also proposes a kind of middle mast embodiment, described middle mast is provided with above-mentioned any described fixing device, in the sunk area that the front panel 4 that described fixing device is arranged on middle mast and base plate 2 form, and the height of described fixing device is lower than the plane of described front panel 4 or equal with the plane of described front panel 4.
In above-described embodiment, the tail end of described front panel 4 is provided with flange 3, is provided with the stiffening rib 21 that is connected with described base plate 2 with described flange 3 in described sunk area, and described fixing chuck plate 1 is fixed on the described stiffening rib 21 by described connected element.
In above-described embodiment, described middle mast is provided with two described fixing devices, two described fixing devices be separately positioned on described front panel 4 and the space that forms between the adjacent stiffening rib 21 with it in, or be arranged in the space that forms between each described stiffening rib 21.
For example: wire rope fixing device is positioned over the middle mast bottom, makes two sections wire rope of coming out of from unit head pressurization pulley to be fixed on smoothly on this wire rope fixing device.The height of this wire rope fixing device is equal to or less than the plane of middle mast front panel, interferes to avoid itself and power head device.This wire rope fixing device has taken full advantage of the space between stiffening rib and the side plate by being bolted on the stiffening rib.Its structural feature is single bolt constraint translation, and one-sided draw-in groove constraint is rotated.The semicircle limited impression of this wire rope fixing device can fix wire rope effectively.
As shown in Figure 3 and Figure 4, the fixing chuck plate 1 of this wire rope fixing device is fixed on the stiffening rib 21 by bolt 14, the draw-in groove 13 of one-sided setting on the fixing chuck plate 1 plays and prevents that the effect of rotating, the limited impression 12 of the inner circular arc on the fixing chuck plate 1 from playing the effect of chucking wire rope.Like this, when middle mast be in level, when down mast is in plumbness, wire rope is in loose condition (of surface).At this moment, strain two sections pressurization wire rope of coming out of from unit head pressurization pulley, then wire rope is pushed gently the limited impression of fixing chuck plate 1.Because 12 pairs of wire rope of limited impression of fixing chuck plate 1 have a resistance, so wire rope can not deviate from.Before rotary drilling rig work, again wire rope is pulled out gently from the limited impression 12 of fixing chuck plate 1.
Need to prove, under the enough situation in space, can then wire rope be snapped in its semicircular limited impression earlier with the fixing chuck plate fit on; Under the situation of insufficient space, can earlier wire rope be snapped in fixing chuck plate, then with the fixing chuck plate fit on.
Alternatively, fixing chuck plate can be welded on the gusset of middle mast.
From the various embodiments described above as can be seen, the utlity model has following advantage:
1) simple, the easy accessibility of fixture structure of the present utility model.
2) fixing device of the present utility model adopts single bolt constraint translation, and one-sided draw-in groove constraint is rotated, and snaps in or when taking out wire rope, and is easy to operate and fixing reliable.
3) fixing chuck plate is fixed on dexterously space between gusset and the front panel (side plate), and with fixing chuck plate by being bolted on the stiffening rib, thereby take full advantage of space between stiffening rib and the front panel, and can effectively fix wire rope.
The utility model embodiment also provides a kind of engineering machinery, rotary drilling rig for example, this project machinery is provided with above-mentioned any middle mast, because above-mentioned any middle mast has above-mentioned technique effect, therefore, the engineering machinery that is provided with this middle mast also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not give unnecessary details now.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
