In this embodiment, a gantry crane wire rope bracket fixture is related, as shown in fig. 1 and 3, which includes a support frame, two rolling support assemblies 200, and a wear-resistant assembly.

The support frame body is used for supporting the two rolling support assemblies 200 and the wear-resistant assembly.

In this embodiment, as shown in fig. 4 and 5, the support frame includes two ear plates 110 disposed at intervals. A wear-resistant accessory support plate 120 is disposed between two spaced apart ear plates 110.

The two drum support assemblies 200 are respectively disposed between the ear plate 110 and the wear-resistant auxiliary support plate 120 on one side and the ear plate 110 and the wear-resistant auxiliary support plate 120 on the other side.

The drum support assembly 200 is rotatably coupled to the ear plate 110 and the wear-resistant auxiliary support plate 120 at both ends thereof, respectively.

The rolling support assembly 200 is used for rolling support of a wire rope.

The wear assembly comprises two wear plates 310. Two wear plates 310 are respectively attached to the inner sides of the two ear plates 110.

The rolling support assembly 200 is in rolling contact with the wire rope during the movement of the wire rope relative to the rolling support assembly 200, and wear on the wire rope can be reduced during the process of supporting the wire rope.

The wire rope can appear jumping relative to the rolling support assembly 200 in the moving process of the rolling support assembly 200, and can contact with the lug plate 110 in the jumping process, and the wire rope can wear the lug plate 110 in the moving process of the wire rope and the lug plate 110.

Thus, the wear assembly comprises two wear plates 310. Two wear plates 310 are respectively attached to the inner sides of the two ear plates 110.

In some embodiments, wear plate 310 is removably coupled to ear plate 110.

Specifically, wear plate 310 is coupled to ear plate 110 by fasteners 320.

Removal and replacement of wear plate 310 may be accomplished by removing fasteners 320 as wear plate 310 wears.

Specifically, two ear panels 110 are disposed in parallel. The ear plate 110 is disposed vertically.

The first step part is provided with a second stop surface.

The first stop surface abuts against the second stop surface.

Accordingly, the stopper plate 130 can prevent the rotation of the first stepped portion 211, thereby preventing the rotation of the spindle 210.

Also, since the end of the mandrel 210 is formed with the first stepped portion 211, the stopper plate 130 can prevent the mandrel 210 from falling off.

And, since the first stop surface abuts against the second stop surface, the rotation of the mandrel 210 can be prevented,

Thereby ensuring that the mandrel 210 does not rotate with the wire rope during movement relative to the rolling support assembly 200.

Two rolling bearings 220 are sleeved outside the mandrel 210, are respectively positioned at two ends of the mandrel 210, and carrier rollers 240 are sleeved outside the two rolling bearings 220.

Two retainers 230 are sleeved outside the mandrel 210 and are positioned on two sides of the two rolling bearings 220. The retainer ring 230 abuts against the outside of the two rolling bearings 220.

A spacer 250 is also provided between the retainer ring 230 and the ear plate 110. The cage 250 is used for positioning the rolling bearing 220.

The spindle 210 is also formed with a stepped shaft at the end with the wear-resistant accessory support plate 120. A second connection hole is formed in the wear-resistant auxiliary supporting plate 120, the second connection hole is a stepped hole, the stepped shaft extends from the second connection hole, and the stepped shaft abuts against the stepped hole. Axial positioning of the mandrel 210 is achieved.

In the present embodiment, two rolling support assemblies 200 are disposed at intervals in the horizontal direction. The axial directions of the two rolling support assemblies 200 are arranged in parallel. The two rolling support assemblies 200 are offset from each other.

Because the two rolling support assemblies 200 are staggered from each other, maintenance and replacement of each rolling support assembly 200 can be facilitated.

In this embodiment, the support housing further includes a bottom plate 140. The lower end of the ear plate 110 is connected to the bottom plate 140. The lower end of the abrasion-resistant auxiliary supporting plate 120 is connected to the bottom plate 140.

Specifically, ear plate 110 is disposed perpendicular to wear-resistant accessory support plate 120 relative to base plate 140.

In some of the present embodiments, the material on the side of the wear-resistant accessory support plate 120 that is adjacent to the rolling support assembly 200 is a wear-resistant material.

In other embodiments, the overall material of wear-resistant accessory support plate 120 is a wear-resistant material.

The auxiliary wear plate serves to prevent wear from occurring due to friction between the wear-resistant auxiliary support plate 120 and the wire rope.

In this embodiment, a distance assembly is connected between the two ear plates 110. The distance assembly serves to prevent the distance between the two ear plates 110 from being deformed under the force of an impact or the like.

A cotter 440 is further provided on the bolt 410 outside the nut 430, the cotter 440 further locking the bolt 410 in position.

Since the bolts are connected between the two lugs 110, the distance of the upper ends of the respective lugs 110 of the chain can be maintained unchanged.

At the same time, the wire rope is prevented from jumping out of the two ear plates 110.

The rolling tube 420 is sleeved outside the bolt 410, and the rolling tube 420 can rotate relative to the bolt 410.

The rolling tube 420 may rotate relative to the bolt 410 during the wire rope contact with the rolling tube 420. Rolling friction is provided between the wire rope and the rolling tube 420. Thereby reducing the friction between the two.

The two ear plates are arranged at intervals, the wear-resistant auxiliary supporting plates 120 are arranged between the two ear plates 110 and are respectively used for rotatably supporting two ends of the two rolling supporting assemblies 200, the rolling supporting assemblies 200 are used for rolling supporting the steel wire ropes, so that the wear of the steel wire ropes is reduced, the wear-resistant plates 310 are arranged on the inner sides of the two ear plates 110, the damage of the ear plates 110 and the steel wire ropes in the relative movement process is prevented, and the wear-resistant plates 310 can be detached to be replaced under the condition that the wear-resistant plates 310 are damaged; in addition, since the two rolling support assemblies 200 are respectively rotatably connected with the adjacent wear-resistant auxiliary support plates 120 and the adjacent ear plates 110, the rolling support assemblies 200 can be independently replaced in the process of damage, so that the cost can be saved, and the labor intensity can be reduced.
