A movable pulley unit (2) with steel wire ropes is arranged on the upper end surface of the equalizing beam (1), a plate hook (3) is mounted below the equalizing beam (1), the plate hook (3) is connected with the lower end surface of the equalizing beam (1) through a suspension fork (4), the upper end of the suspension fork (4) is connected with lower end surface of the equalizing beam (1) through a pin (5), and the upper portion of the plate hook (3) penetrates into the lower end of the suspension fork (4) and is connected with the lower end of the suspension fork (4) through a suspension fork pin (6).

Description

A kind of gantry hook

Technical field

The utility model relates to a kind of metallurgical casting hoisting crane, particularly a kind of gantry hook.

Background technology

The used fixedly gantry hook of existing metallurgical casting hoisting crane mainly comprises equalizing bar, plate hook and is arranged on the running block of equalizing bar upper surface; Wherein plate hook directly is connected with equalizing bar through the pin that is arranged in the equalizing bar; There is following shortcoming in such structure: 1. because gantry hook is a rivet welding spare; Have manufacturing errors during fabrication, plate hook is directly through pin and the distance adjustment that can't carry out after equalizing bar is connected between the plate hook.2. though steel rope is wrapped on the running block, the termination of steel rope but is connected on the walking dolly of gantry hook top, when needs more during change steel rope, changes very inconvenient.

The utility model content

The purpose of the utility model just provides a kind of gantry hook that can carry out size adjusting between the plate hook during fabrication.

The purpose of the utility model is to realize through such technical scheme; A kind of gantry hook comprises equalizing bar, is provided with the running block of band steel rope in the equalizing bar upper surface; Below equalizing bar, be provided with plate hook, said plate hook is connected with the equalizing bar lower surface through hanging fork.

Wherein, said upper end of hanging fork is connected with the equalizing bar lower surface through pin, and the top of said plate hook penetrates in the lower end of hanging fork and through hanging bolt and connects.

Change steel rope more for ease; The said T type equalizer bar that on running block, vertically is provided with; Said T type equalizer bar is connected with running block through bearing, is respectively arranged with wire rope grip in the both sides on T type equalizer bar top, and the termination of said steel rope is connected with wire rope grip.

Owing to adopted technique scheme; The utlity model has structure design ingenious, make convenient installation, adopt and not only can adjust the size between the plate hook during fabrication, the error that can bring because of manufacturing; Simultaneously, can also change steel rope easily.

Description of drawings

The description of drawings of the utility model is following:

Fig. 1 is the structural representation of the utility model;

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

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.

Embodiment 1: like Fig. 1, shown in 2, a kind of gantry hook comprises equalizing bar 1, is provided with the running block 2 of band steel rope in equalizing bar 1 upper surface, below equalizing bar 1, is provided with plate hook 3, and said plate hook 3 is connected with equalizing bar 1 lower surface through hanging fork 4.

Further describe, above-mentioned upper end of hanging fork 4 is connected with equalizing bar 1 lower surface through pin 5, and the top of said plate hook 3 penetrates in the lower end of hanging fork 4 and through hanging bolt 6 and connects.

Connection through hanging fork 5 and hanging bolt 6 between equalizing bar 1 and the plate hook 3, when installing and use gantry hook, size can be regulated, and has prevented owing to scale error is rectified and improved framing member, thereby has reduced cost, has improved capacity rating.

Wherein, the said T type equalizer bar 7 that on running block 2, vertically is provided with, said T type equalizer bar 7 is connected with running block 2 through bearing; Both sides on T type equalizer bar 7 tops are respectively arranged with wire rope grip 8; The termination of said steel rope is connected with wire rope grip 8, and such when being arranged so that more change steel rope, the operator directly changes at the running block place and gets final product; Make things convenient for replacing, improved work efficiency.
