Abstract
A long spiral drilling machine top pulley 360-degree rotating mechanism comprises a main winch pulley frame and an auxiliary winch pulley frame, wherein the main winch pulley frame is installed on the top of a stand column of a drilling machine through a connecting part, and the auxiliary winch pulley frame is combined with the main winch pulley frame. The rotating mechanism is characterized in that a cantilever type arm rest used for installation of the auxiliary winch pulley frame is arranged on one side of the main winch pulley frame in the mode that the cantilever type arm rest is perpendicular to the side wall of the main winch pulley frame; the auxiliary winch pulley frame is hung at the horizontal extending end of the cantilever type arm rest through a rotating hinge pin which is arranged in the mode that the rotating hinge pin is vertical to the axis of the cantilever type arm rest, the lower extending line of the axis of the rotating hinge pin vertically intersects with the axis of the axle of an auxiliary winch pulley installed on the auxiliary winch pulley frame, and therefore a universal joint structure is formed. The universal joint structure is mainly used for the rotating mechanism, the auxiliary winch pulley can rotates in the radial direction while rotating in the axial direction, and a guide baffle is arranged on one side of the auxiliary winch pulley, so the auxiliary winch pulley frame can still rotate in the direction of a steel wire rope head when hoisting heavy objects, the directions of the auxiliary winch pulley and the auxiliary winch pulley frame are kept consistent, the problems that a steel wire rope disengages from a groove, the hoisting range is small and hoisting is not convenient to carry out are solved, production efficiency is improved, and operation delay caused by groove disengagement of the steel wire rope and risk brought by climbing at high altitudes are avoided.
Description
Technical field
The utility model relates to long spiral preparation of construction, is that one can 360 ° of rotating anticreep groove derricking gears.
Background technology
At present, in long spiral industry preparation of construction, rely on secondary elevator to realize the effect of auxiliary lifting.Top pulleys structure adopts in-line or Y-shaped structure.Independently secondary elevator pulley yoke of nothing in these two kinds of structures, spider-less structure, secondary elevator pulley yoke cannot be realized 360 ° and freely turn round, without pulley revolution guide piece.Cause that lifting scope is little, easily de-groove, operating efficiency are low for steel rope.
Summary of the invention
The purpose of this utility model provides a kind of more convenient operation for existing weak point in above-mentioned prior art just, and practicality is stronger, 360 ° of swing type mechanisms of long-spiral drilling machine top pulleys that fault rate is lower.
The purpose of this utility model can realize by following technique measures:
360 ° of swing type mechanisms of long-spiral drilling machine top pulleys of the present utility model comprise by attaching parts and are arranged on the master winch pulley yoke (top pulleys of Y-shaped structure or be called gooseneck boom, cathead) at rig column top and the secondary elevator pulley yoke combining with master winch pulley yoke; In master winch pulley yoke one side, to be provided with the cantilevered jib for secondary elevator pulley yoke is installed with the perpendicular mode of master winch pulley yoke side wall surface; Described secondary elevator pulley yoke is the horizontal-extending end at cantilevered jib by the revolution bearing pin hanging to arrange with the perpendicular mode of the axis of cantilevered jib, and the lower extended line of described revolution bearing pin axis intersects vertically with the axle axis that is arranged on the secondary elevator pulley on described secondary elevator pulley yoke, forms cross axle structure.
The utility model is provided with deflector apron in secondary elevator pulley one side.
The beneficial effects of the utility model are as follows:
The utility model is used on long screw top pulley, under the traction of steel wire rope head, realizes when bearing heavy burden load and completes revolution, and degreeof turn reaches 360 °, increases lifting scope, effectively prevents steel cable slot disengaging, thereby improve operating efficiency.

Detailed description of the invention
The utility model is further described below with reference to example (accompanying drawing):
As shown in Figure 1, 2,360 ° of swing type mechanisms of long-spiral drilling machine top pulleys of the present utility model comprise that the master winch pulley yoke 2(of Y-shaped structure that the two ends that are arranged on rig column top by attaching parts are separately installed with master winch pulley 1 is referring to Fig. 4,5) and the secondary elevator pulley yoke 3 that combines with master winch pulley yoke; In master winch pulley yoke one side, to be provided with the cantilevered jib 5 for secondary elevator pulley yoke is installed with the perpendicular mode of master winch pulley yoke side wall surface; Described secondary elevator pulley yoke 3 is by hanging the horizontal-extending end at cantilevered jib with the revolution bearing pin 10 arranging with the perpendicular mode of the axis of cantilevered jib 5, and the lower extended line of described revolution bearing pin 10 axis and the intersect vertical axis of wheel shaft 11 that is arranged on the secondary elevator pulley 12 on described secondary elevator pulley yoke 3, form cross axle structure.
The utility model is provided with deflector apron 4 in secondary elevator pulley one side.
More specifically, described revolution bearing pin 10 is arranged on the horizontal-extending end of cantilevered jib by upper end bearing 8, bottom end bearing 9, limit baffle ring, gland cover 7 and jam nut 6 etc.; Secondary elevator pulley 12 is arranged on secondary elevator pulley yoke 3 by bearing pin, and secondary elevator pulley yoke 3 is provided with pulley yoke revolution deflector apron 4.Degreeof turn of the present utility model reaches 360 °, and lifting scope is increased greatly, effectively avoids the generation of de-groove fault simultaneously, improves operating efficiency, more convenient operation.
Principle of work of the present utility model is as follows:
as shown in Figure 4,5, swing type mechanism of the present utility model is arranged on long-spiral drilling machine column top, and the auxiliary pulley that secondary hoisting rope rolls out rope process top pulleys frame from pair, to level ground, is fixed on the weight that will lift by crane.When hoisting heavy (weight is likely local arbitrarily all around at rig), secondary elevator pulley is along with the traction of steel rope is turned round towards the direction of weight, like this, steel rope rope outlet direction points to weight all the time, the de-groove fault causing while effectively having avoided side direction lifting.
