Abstract

The utility model discloses a power head installation bracket for a raise boring machine. The power head installation bracket for the raise boring machine comprises a guide post (3) which is formed by welding guide sleeves (8), lifting lugs (9), a top plate (10), side plates (11), a bottom plate (12) and a power head installation plate (13); the upper end of the guide post is hinged with the lower end of a lifting bracket (1); the lower end of the guide post is connected and fixed with a rack base (6) by bolts; the upper end of the guide post is connected with a top fixing plate (2) by bolts; the lifting bracket is hinged with a feed cylinder (5); the guide post is connected with a full hydraulic power head (4) by bolts; and the rack base is connected with a rack supporting seat (7) through a pin shaft. Compared with the prior art, the power head installation bracket has the advantage that the bearing capacity of each guide sleeve is reduced under the same load in the mode that the power head installation bracket adopts four guide sleeves, so that the drilling process is more stable; and the displacement deflection of the power head during high torque drilling is reduced.

Description

Raise boring machine unit head mounting bracket

Technical field

The utility model relates to a kind of raise boring machine installing component, specifically is a kind of raise boring machine unit head mounting bracket.

Background technology

At present in the anti-well engineerings such as colliery, metallurgy, water power, special major diameter gravity vent, pressure pipeline equal aperture are greater than 3m, and in the prior art, mining large-scale raise boring machine drilling ability is less, under big load, the bearing capacity of each unit head mounting bracket fairlead is big, very easily causes and creeps into instability, the problem that the displacement deflection of unit head when high pulling torque creeps into is bigger makes workmanship and progress be affected then.

The utility model content

Problem at above-mentioned prior art existence, the utility model provides a kind of raise boring machine unit head mounting bracket, is implemented under the same load, reduces the bearing capacity of each fairlead, make drilling process more stable, reduce the displacement deflection of unit head when high pulling torque creeps into.

To achieve these goals, the utility model comprises the lead that is made of fairlead, hanger, top board, side plate, base plate and the welding of unit head installing plate;

The lead upper end is hinged with the lower end of hoisting bracket, lead lower end and gantry base are connected and fixed with bolt, the upper end is connected with the top fixed head with bolt, hoisting bracket and feed cylinder are hinged, lead is connected with screw with all-hydraulic power head, and gantry base is connected on the frame support seat by bearing pin.

Guiding is with four, is distributed on four angles of lead.

The beneficial effects of the utility model are: compared with prior art, the mode that this unit head mounting bracket adopts four fairleads has realized reducing the bearing capacity of each fairlead under same load, make drilling process more stable, reduce the displacement deflection of unit head when high pulling torque creeps into.

Fig. 1 is the main overall structure schematic diagram of looking;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is four fairlead unit head supports;

Fig. 4 is four fairlead unit head support upward views.

Among the figure: 1, hoisting bracket, 2, the top fixed head, 3, lead, 4, unit head, 5, feed cylinder, 6, gantry base, 7, the frame support seat, 8, fairlead, 9, hanger, 10, top board, 11, side plate, 12, base plate, 13, the unit head installing plate.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 3 and Figure 4, this unit head mounting bracket comprises the lead 3 that is made of fairlead 8, hanger 9, top board 10, side plate 11,

base plate

12 and 13 welding of unit head installing plate.

As depicted in figs. 1 and 2, the lower end of the upper end of lead 3 and hoisting bracket 1 is hinged, the lower end of lead 3 and gantry base 6 usefulness high-strength bolts are connected and fixed, the upper end is connected with top fixed head 2 with high-strength bolt, hoisting bracket 1 is hinged with feed cylinder 5, lead 3 and all-hydraulic power head 4 are connected with screw, and gantry base 6 is connected on the frame support seat 7 by bearing pin.

Fairlead 8 has four, is distributed on four angles of lead 3.

[0014] this unit head mounting bracket has been realized reducing the bearing capacity of each fairlead under same load, makes drilling process more stable, reduces the displacement deflection of unit head when high pulling torque creeps into.
