Problems solved by technology

(3) There is a gap between the horizontal guide wheel and the track. When the wheel wears to a certain extent, the gap must be readjusted. However, the existing assembly and disassembly methods are cumbersome, which not only increases maintenance costs, but also delays production tasks

Embodiment 1

[0029] The utility model relates to a horizontal wheel anti-gnawing rail device of a two-force bar system. The device as figure 1 As shown, it includes four two-force link mechanisms, the fixed ends of the four two-force link mechanisms are symmetrically fixed on the four corners of the main girder 1 of the bridge frame, and the four two-force bar mechanisms are located on both sides of the main beam 1 of the bridge frame. Such as Figure 4 As shown, the installation gap e between the movable ends of the four two-force lever mechanisms and the inner side of the track 5 is 4-6mm. Such as figure 2 As shown, the stiffener plate is welded at the end of main beam 1 and the outer web.

[0030] The size and structure of the 4 two-force lever mechanisms are identical, and all consist of a fixed frame group and a horizontal wheel group.

[0031] Such as image 3 As shown, the fixed frame set includes a box-shaped fixed frame 2 , a pressing frame 3 and a compression spring 15 ...

Embodiment 2

[0036] The utility model relates to a horizontal wheel anti-gnawing rail device of a two-force bar system. Except following technical parameter, all the other are with embodiment 1.

[0037] The installation clearance e between the movable ends of the four two-force rod mechanisms and the inner side of the track 5 is 6-8 mm; there are 5-8 radial oil holes on the wall of the stepped hole of the shaft sleeve 13; the eccentric transparent cover 9 is evenly arranged with 4 ~7 or 9~12 screw holes; the distance between the eccentric holes of the eccentric transparent cover 9 is b=20~25mm.

[0038] In this specific embodiment, during installation, the vertical centerline of the wheel 6 and the vertical centerline of the track 5 tend to be close to or even overlap, so as to balance the force couple and the reaction couple produced by the lateral force on the track 5 on both sides, and reduce the size of the lateral force on the rail. .

[0039] Compared with the prior art, this spec...

Abstract

The invention relates to a horizontal wheel rail gnawing preventing device for a two-force rod system. The technical scheme is as follows: the device comprises four two-force rod mechanisms with the same size and structure, and the four two-force rod mechanisms are symmetrically fixed on four corners of a bridge girder (1). Each two-force rod mechanism is composed of a fixed frame set and a horizontal wheel set, wherein the fixed frame set comprises a box-shaped fixed frame (2), a pressing frame (3) and a compression spring (15); the horizontal wheel set comprises a horizontal wheel (4), a bearing (8), an eccentric transparent cover (9), an adjustable pad (10), a wheel axle (12) and a shaft sleeve (13). The box-shaped fixed frame (2) is fixed on web plates at two sides of the bridge girder (1); the pressing frame (3) slides inside the box-shaped fixed frame (2) through the compression spring (15); and the horizontal wheel (4) is fixed on the pressing frame (3) through the bearing (8), the wheel axle (12) and the eccentric transparent cover (9). By using the horizontal wheel rail gnawing preventing device, the precise guide for the operation of a crane is realized; and a track (5) is in flexible contact with the horizontal wheel (4), thus the wheel rail gnawing phenomenon is effectively avoided. The horizontal wheel rail gnawing preventing device has the characteristics of simple structure, easiness for maintenance, strong stability and long service life.

Description

technical field [0001] The invention belongs to the technical field of anti-gnawing rail devices for crane operating mechanisms. Specifically relates to a horizontal wheel anti-gnawing rail device of a two-force bar system. Background technique [0002] The traveling mechanism of the large-span bridge crane usually adopts double rim wheels, and the function of the rims is to guide and bear the horizontal lateral force during deflection operation. When the crane encounters problems such as "improper wheel assembly position", "large difference in track height or parallelism", "bridge frame deformation", etc., it is very easy to cause the deflection of the wheels, and not only will there be extreme accidents between the wheels and the track A large impact will also cause serious wear, which is called rail gnawing. The data shows that it is quite common for bridge cranes to gnaw rails during operation, especially in the metallurgical industry with high loads. The accidents of ...
