Problems solved by technology

[0003] 1. Use high-strength bolts to connect and fix the stud base and the lower base plate, relying on friction to prevent the movement of the support. Although the friction surfaces have been treated, the load capacity is still limited, and it is not practical for the case of excessive load. up
[0004] 2. To loosen or tighten high-strength bolts, a torque wrench is often used, which is inconvenient to operate
[0005] 3. This structure is still relatively large, and it is difficult to operate in the narrow space of the track beam support

Embodiment Construction

[0024] figure 1 It is a half-section diagram of an embodiment of the horizontal adjustment support of the present invention. The horizontal adjustment support of the present invention is composed of a top plate 1, a top seat 2, a ball hinge 3, a stud 4, a lock nut 5, a lock screw 52, ​​a stud base 6 and Bottom plate 7 forms, and its characteristic is:

[0025] There are protruding shoulders 771, 772, 773, 774 around the base plate 7. The flange 64 of the stud base 6 is square or rectangular and is provided with a transverse waist hole 63. The stud base 6 is placed around the base plate 7. In the pit surrounded by the shoulders, a wedge-shaped space 8 is formed between both sides of the base flange 64 and the bottom plate shoulders 771, 773, and a wedge 81 and four wedges, etc., can be inserted in the two wedge-shaped spaces 8. Thick plug irons 82, 83, 84, 85 are provided with screw holes 71 at the position of the base plate 7 relative to the transverse waist hole 63 of the ba...

Abstract

A transversely adjustable supporter is composed of top plate, top seat, ball-and-socket connector, screw bolt, lock nut, setting-up screw, screw bolt base and bottom, plate, and features that the said bottom plate has convex shoulders at 4 edges, the square or rectangular flanger of screw bolt base has transverse holes, there are two wedge spaces between the both sides of the said flange and a pair of the said shoulders for inserting a wedge block and several iron plugs, and the said bottom plate has screw holes opposite to the said transverse holes for joining the said base and bottom plate by screw bolts.

Description

technical field [0001] The invention relates to an adjustable support, in particular to a lateral adjustment support used for installation of elevated road beams, rail vehicle track beams and magnetic levitation railway track beams. Background technique [0002] The invention patent "adjustable support" applied by the applicant (application number: 01126627.9, application date: September 4, 2001) proposed adjustable track beam fixed support, adjustable track beam one-way movable support and adjustable track The two-way movable support of the beam adopts studs and stud bases, lock nuts, lock screws and spherical hinge systems, which solves the problem of vertical adjustment of the support; at the same time, it is composed of stud bases, lower bottom plates and high-strength bolts The horizontal adjustment system also basically solves the problem of lateral adjustment of the support, but the horizontal adjustment system is not perfect, because: [0003] 1. Use high-strength b...
