Abstract
The utility model discloses a mast connection mechanism for rotary digging machines. The utility model has the main technical scheme that a mast is provided with a rectangular through hole; a crossed block is arranged in the through hole; the crossed block is connected with an amplitude changing triangular block through a pin shaft; the rise, the left swing and the right swing of the mast and the rotation of the triangular block are all carried out round a central shaft of the crossed block; an installation gap reserved between the crossed block and the mast needs eliminating; a high strength nylon plate is arranged in the gap, and a circle of threaded bolts are arranged under the high strength nylon plate. The threaded bolts are regulated for tightly pushing the nylon plate for eliminating the gap between the mast and the crossed block for preventing the slack and the slide between the mast and the crossed block according to the gap. The utility model has the advantages of simple structure and better slack and slide resisting effect.
Description
Technical field
A kind of mechanical device of the utility model for realizing that the rotary drilling rig mast is connected with the jib lubbing mechanism corner block especially can prevent mast and be connected the sliding bindiny mechanism of cross piece pine.
Technical background
At present, the structure that domestic existing rotary drilling rig mast is connected with the jib lubbing mechanism corner block all is that the belly at mast welds a circular trough, a plectane is connected in this groove by bolt again, and the corner block of jib lubbing mechanism is connected on the plectane in the groove by bearing pin.This form of structure assemblage gap between better controlled plectane and the mast of having no idea, and this gap can cause that mast rocks, thereby the beyond thought consequence of unstable initiation when causing whole equipment to be worked, and sleeve mechanism not only takes up room in the outside of mast, outward appearance mixed and disorderly but also poor stability.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, a kind of mast bindiny mechanism is provided, the sleeve mechanism design links to each other with the luffing corner block by a cross piece in mast and can effectively control above-mentioned assemblage gap, strengthens the stability of equipment greatly and saves the space.
The technical scheme that the utility model adopted is: a kind of rotary drilling rig mast bindiny mechanism, it is characterized in that it comprises a cross piece, one central rotating shaft, two make the bearing pin that is connected that cross piece and luffing corner block link to each other, one is loosened the high-strength nylon plate, one border holds out against the bolt that loosens plate and prevents the border locking nut that the bolt pine is unloaded, on mast, have a rectangular through holes, described cross piece is installed in the mast through hole, the center that central rotating shaft vertically passes the cross piece links together mast and cross piece, two that cross piece and luffing corner block are coupled together are connected bearing pin and are distributed in cross piece both lateral sides, loosening the high-strength nylon plate is installed between cross piece and the mast, the puller bolt border be distributed on loosen the high-strength nylon plate under, locking nut is close to mast and is contained in respectively on every puller bolt.Owing to adopted such scheme, mast hoist, swing and the rotation of corner block all around the central axis expansion of this cross piece, and the assemblage gap that is stayed between cross piece and mast is exactly the gap that will eliminate.A high-strength nylon plate of installing in this gap is also thereunder adorned a border bolt, eliminates gap between mast and the cross piece and reaches the purpose that prevents mast and the loose cunning of cross piece thereby make it to press closer all the time nylon sheet according to these bolts of gap adjustment.
The beneficial effects of the utility model are, the simple and stable that is connected of mast and luffing corner block, and elimination mast that can be convenient and simple and the gap between the cross piece prevent that effectively both from the sliding phenomenon of pine occurring, and be simple in structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the longitudinal sectional view of present embodiment;
Fig. 2 is that the A-A of Fig. 1 is to view.
Among the figure: 1, locking nut, 2, bolt, 3, nylon block, 4, bearing pin, 5, the luffing corner block, 6, mast, 7, the cross piece, 8, central rotating shaft.
The specific embodiment
As shown in Figure 1, cross piece (7) is installed in the mast (6) and by bearing pin (4) and links to each other with luffing corner block (5), and mast (6) can swing 5 ° around the central rotating shaft (8) that links to each other with cross piece (7).Be the gap of when in mast (6), cross piece (7) being installed, leaving for convenience detach between the two, eliminate the gap that cross piece (7) generation is installed by a high-strength nylon piece (3) being installed again and being pressed closer nylon block (3) with a border bolt (2) between mast (6) and cross piece (7), unload 1 locking nut of installation on every bolt for preventing bolt (2) pine.Like this with regard to convenient and safe elimination cause the gap that mast rocks, for the work of equipment safety and stability provides effective assurance.
