Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, the connection set of a kind of base and its support is provided, solve being connected of present large-scale mine disintegrator drive unit base and its support, adopt welding, common bolt mode dismounting difficulty, adopt the large technical problem of pin Placement operation easier.
The utility model is achieved through the following technical solutions:
The connection set of a kind of base and its support, it is characterized in that: described connection set is by base, support, bearing pin, expansion sleeve, the ear seat, stove bolt, packing ring forms, be welded with upper ear seat on the described base, be welded with lower ear base in the described support, be processed with identical pilot hole on described upper ear seat and the lower ear base, right expansion sleeve is installed in the pilot hole of described upper ear seat, left expansion sleeve is installed in the pilot hole of described lower ear base, the endoporus of described right expansion sleeve and left expansion sleeve is taper hole, after the big opening end alignment of two taper holes a bearing pin is set therein, the profile of described bearing pin matches with two described taper holes, the flange of described right expansion sleeve is by some stove bolts, packing ring and upper ear seat are fastening, and the flange of described left expansion sleeve is by some stove bolts, packing ring and lower ear base are fastening.
Further, between the flange of described right expansion sleeve and the described upper ear seat, all leave the safety space between the flange of described left expansion sleeve and the described lower ear base.
Further, the flange of described right expansion sleeve and left expansion sleeve is provided with additional threaded bores, and the specification of additional threaded bores is identical with tapped hole specification on the ear seat.
The utility model compared with prior art because described connection set adopts a plurality of bolts than small dimension, just can be with the connection set pretension by less pretightening force.Avoid using the bolt of large specification, thereby simplify the mounting or dismounting program.When pretension, only need to use torque spanner to carry out pretension to the bolt on the described connection set, need not use hydraulic spanner.Simultaneously, described connection set compact structure, thus it is little to take up room; Processing and fabricating is easier to, and dismounting is easy to maintenance, operability good.

Embodiment
Such as Fig. 1,2,3, shown in 4, the connection set of a kind of base and its support, by base 1, support 2, bearing pin 3, expansion sleeve 4, ear seat 5, stove bolt 6, packing ring 7 forms, be welded with upper ear seat 5-1 on the described base 1, be welded with lower ear base 5-2 in the described support 2, be processed with identical pilot hole on described upper ear seat 5-1 and the lower ear base 5-2, right expansion sleeve 4-1 is installed in the pilot hole of described upper ear seat 5-1, left expansion sleeve 4-2 is installed in the pilot hole of described lower ear base 5-2, the endoporus of described right expansion sleeve 4-1 and left expansion sleeve 4-2 is taper hole, after the big opening end alignment of two taper holes a bearing pin 3 is set therein, described bearing pin 3 matches with two described taper holes, the flange of described right expansion sleeve 4-1 is by some stove bolts 6, packing ring 7 is fastening with upper ear seat 5-1, and the flange of described left expansion sleeve 4-2 is by some stove bolts 6, packing ring 7 is fastening with lower ear base 5-2.
Between the flange of described right expansion sleeve 4-1 and the described upper ear seat 5-1, all leave safety space H between the flange of described left expansion sleeve 4-2 and the described lower ear base 5-2.
The flange of described right expansion sleeve 4-1 and left expansion sleeve 4-2 is provided with additional threaded bores E, and the specification of additional threaded bores E is identical with tapped hole specification on the ear seat.
The below is elaborated to the installation method of described connection set
1. the installation of bearing pin 3 and expansion sleeve 4
1.1 drive unit base 1 passed and supported 2 ear seat positions of aliging separately, will be with pack into the smoothly connecting pore place of ear seat one side of the expansion sleeve 4 that loosers a bolt, prevent the inclination of base 1 and support 2, then with hand with bolt tightening.
1.2 bearing pin 3 is smoothly packed in the taper hole of 1.1 described expansion sleeves 4.
1.3 will to prevent base 1 and the inclination of supporting 2 with smoothly pack into the other end of 1.2 described bearing pins of the expansion sleeve 4 that loosers a bolt, then with hand with bolt tightening.
1.4 by regulating the position of bearing pin 3 two ends expansion sleeves 4 relative ear seats 5, in order to allow the middle position of bearing pin 3 as close as possible a pair of ear seats.
2. tighten the method for expansion sleeve bolt 6
2.1 the tightening of bolt 6 should use torque spanner by diagonal angle, intersection, tighten equably.
2.2 the screw-down torque value (being assumed to M) of bolt 6 can be with reference to the torque value of tightening of screw in JB/T7934-1999 table 1, the table 2, and follows these steps to carry out:
