Abstract
The utility model provides a winding auxiliary device for a drill tower guiding frame. The winding auxiliary device comprises a guide frame striding over the upper part of a winding cylinder, wherein a second roller positioned at the upper part of the winding cylinder and a first roller positioned at the upper part of the second roller are mounted on the guide frame; the central shaft of the first roller and the central shaft of the second roller are both parallel to the central shaft of the winding cylinder; the length of the winding cylinder is greater than that of the second roller, and the length of the second roller is greater than that of the first roller. The winding auxiliary device lowers the axial impact caused by horizontal swing of a wire rope on a pulley, reduces abrasion of the pulley caused by the wire rope, and effectively prevents the wire rope from divorcing from the pulley.
Description
technical field
The utility model relates to a kind of boring tower guide frame winding auxiliary device of geological exploration field.
background technology
The drilling tool lifting of geoexploration boring tower generally completes by winch, and the steel rope being wrapped on winding drum is walked around the pulley and the outer end connecting shackle that are arranged on boring tower.In use find, elevator when rope row, because the steel rope amplitude that swings is excessive, pulley is produced to lateral action power, two side shields of frequent impact pulley, cause pulley both sides serious wear.The phenomenon (being commonly called as rope skipping phenomenon) that there will be steel rope to depart from from pulley when serious, not only affects work efficiency, and exists great safety hidden.
utility model content
Technical problem to be solved in the utility model is, a kind of boring tower guide frame winding auxiliary device is provided, and reduces the axial impact that steel rope swings to pulley, to reduce the wearing and tearing of steel rope to pulley, and effectively prevents that steel rope from departing from from pulley.
The technical solution adopted in the utility model is as follows:
Boring tower guide frame winding auxiliary device, comprise the winding drum that is arranged on boring tower one side, it is characterized in that: also comprise the guide frame that straddles described winding drum top, the second tin roller that is positioned at winding drum top and the first cylinder that is positioned at second tin roller top are installed on described guide frame; The center shaft of described the first cylinder and the center shaft of second tin roller all parallel with the center shaft of winding drum; The length L of winding drum
1be greater than the length L of second tin roller
2, the length L of second tin roller
2be greater than the length L of the first cylinder
3.
Preferably, L
1=2L
2～3L
2, L
2=2L
3～3L

Good effect of the present utility model is:
The utility model has been set up guide frame, and adopts two cylinders to lead to steel rope, because the driving surface of cylinder is larger, so steel rope can swing on cylinder.On the other hand, because the length of winding drum, second tin roller and the first cylinder is dwindled from bottom to top gradually, therefore on winding drum, the amplitude of fluctuation of steel rope also reduces from bottom to top gradually, after conducting to pulley, this amplitude of fluctuation is smaller, the swing of steel rope is effectively dwindled the impact of boring tower top sheave, thereby has alleviated the axial impact force of steel rope to pulley, thereby has reduced the wearing and tearing of pulley, extend service life, and eliminated the potential safety hazard that steel rope departs from from pulley.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the shape schematic diagram of the utility model cylinder.
Detailed description of the invention
Further illustrate the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, the utility model comprises the winding drum 6 that is arranged on boring tower 2 one sides, also comprise the guide frame 8 that straddles described winding drum 6 tops, on described guide frame 8, be provided with and be positioned at the second tin roller 5 of winding drum 6 tops and be positioned at the first cylinder 9 of second tin roller 5 tops, the center shaft of the center shaft of described the first cylinder 9 and second tin roller 5 all parallels with the center shaft of winding drum 6.The length L of winding drum 6
1be greater than the length L of second tin roller 5
2, the length L of second tin roller 5
2be greater than the length L of the first cylinder 9
3.Preferably, L
1=2L
2～3L
