Abstract

The utility model relates to a double-jaw grab with a dust cover, characterized in that a guide roller and a fixed pulley of steel rope are arranged on the upper and lower end of an upper bearing beam; a left strut and a right strut are respectively arranged on the both ends of the upper bearing beam; a left bucket body and a right bucket body are articulated with the lower ends of the left strut and right strut; a lower bearing beam and a movable pulley thereof are articulated with the upper end of the opposite port of the left and right bucket body; the steel rope which makes the left bucket body and right bucket body open and close is arranged on the guide roller of the fixed pulley and the movable pulley; a left dust cover and right dust cover are respectively arranged on the left strut and right strut of the left bucket body and right bucket body to prevent the bulk goods in the grab from blowing by the wind, thus the environmental pollution is reduced. The utility model is provided with advantages of simple structure, easy manufacturing, etc.

Description

The cham shell grab that has dust cap

Technical field

The utility model relates to a kind of grab bucket that is used to load and unload bulk goods, especially a kind of cham shell grab that has dust cap.

Background technology

Cham shell grab is that a kind of port and pier uses comparatively general bulk-handling equipment, the structure of traditional cham shell grab is that the lower end of deck beam is equipped with fixed pulley, the two ends of deck beam are hinged left strut and right strut respectively, hinged respectively left bucket body and the right bucket body that has middle hinge shaft in the lower end of whisker boom, the hinged through beam that has movable pulley on the middle hinge shaft of left and right sides bucket body is equipped with the wire rope that left and right sides bucket body is opened and closed on fixed pulley and the movable pulley.The grab bucket of this structure upper end is to be opening-wide state, and therefore the pollution surrounding enviroment are flown away at the bulk goods place of bending with the wind in the grab bucket when the weather of wind.

Summary of the invention

The utility model provides a kind of cham shell grab that has dust cap that keeps clean environment for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:

A kind of cham shell grab that has dust cap, by deck beam, be installed in the fixed pulley of deck beam lower end, be installed in the guide roller of deck beam upper end, be hinged on the whisker boom at deck beam two ends, be hinged on the whisker boom lower end have in the middle of the left bucket body and the right bucket body of jointed shaft, be hinged on the through beam and the fixed pulley of the middle jointed shaft of left bucket body and right bucket body, the wire rope that left bucket body and right bucket body are opened and closed that is installed on fixed pulley and movable pulley and the guide roller is formed, be fixed with left dust cap and right dust cap on the described strut respectively, two dust caps bend with a metal sheet respectively and form, and its cross section is the grooved of symmetry.

Advantage and the good effect that the utlity model has are: owing on the left and right strut on the bucket body of the left and right sides left and right dust cap is installed, blocked wind brushing to the bulk goods in grabbing bucket, greatly reduce the environment pollution of bulk-handling, make port and pier, boats and ships sanitation and hygiene more, advantage simple in structure, that be easy to make that the utility model also has.

Description of drawings

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

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: the strut of a 1-left side; 2-left side bucket body; The 3-through beam; The 4-guide roller; The 5-deck beam; The 6-fixed pulley; The 7-movable pulley; The 8-wire rope; The right bucket body of 9-; The right strut of 10-; The right dust cap of 11-; The 12-screw; 13-left side dust cap; The 14-screw.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:

See also Fig. 1, the top and bottom of deck beam 5 are separately installed with the guide roller 4 and the fixed pulley 6 of wire rope 8, the two ends, the left and right sides of deck beam are hinged with left strut 1 and right strut 10 respectively, the lower end of left side strut and right strut is hinged left bucket body 2 and right bucket body 9 respectively, the common hinged through beam 3 that has movable pulley 7 in the upper end of a left side bucket body and right bucket body counterpart is equipped with the wire rope that left bucket body of control and right bucket body open and close on the fixed pulley of the movable pulley of through beam, deck beam and guide roller.In order to prevent air intake in left bucket body and the right bucket body, on left bucket body and left strut above the right bucket body and right strut, be separately installed with left dust cap 13 and right dust cap 11 and

trip bolt

12 and 14, left and right dust cap bends with a metal sheet respectively and forms, its cross section is the grooved for symmetry, as shown in Figure 2, left and right dust cap is switch with the switching of left and right bucket body, can prevent effectively like this that wind from entering blows afloat fully loaded bulk goods in the left and right bucket body and pollutes surrounding environment, reaches the purpose of loading and unloading environment sanitation and hygiene.

Claims

1. cham shell grab that has dust cap, by deck beam, be installed in the fixed pulley of deck beam lower end, be installed in the guide roller of deck beam upper end, be hinged on the whisker boom at deck beam two ends, be hinged on the whisker boom lower end have in the middle of the left bucket body and the right bucket body of jointed shaft, be hinged on the through beam and the fixed pulley of the middle jointed shaft of left bucket body and right bucket body, the wire rope that left bucket body and right bucket body are opened and closed that is installed on fixed pulley and movable pulley and the guide roller is formed, it is characterized in that: be fixed with left dust cap and right dust cap on the described strut respectively, two dust caps bend with a metal sheet respectively and form, and its cross section is the grooved of symmetry.
