Abstract

The utility model discloses a portable manpower grab, belonging to the type of tools. The utility model is characterized in that a draw rod whose flexion is driven by a pressure rod is arranged in the cavity of a loop rod, and the pressure rod is hinged at the upper end of the draw rod by a shaft. The pressure rod and the loop rod are mutually hinged by a supporting arm, and a symmetrical switching grab is hinged by a connection arm and a rotation shaft on a transverse shaft positioned at the lower end of the loop rod and a transverse shaft of the draw rod positioned at the lower end of the draw rod. The draw rod can be flexed in a cavity rod by the reciprocating wrench the pressure rod, the grab positioned at the lower end of the draw rod and the loop rod is driven, and the switching is realized. The utility model has the advantages of convenient operation, and high work efficiency, and the sludge in one launch caisson can be cleaned to cleanness with labor-saving.

Description

Portable manpower grab

The utility model relates to the employed instrument of mud in a kind of cleaning sewer pipe open caisson.

The sewer pipe open caisson of urban road both sides, every interval some months just should be cleared up primary sludge, and present employed cleaning tool is very backward.Cooperated to carry out by two people when the cleaning open caisson, a people uses right angle type side's spade to put into open caisson, and another people user spade is stirred mud in right angle type side's spade, because open caisson is young, spade is not used power elongated, and efficient is very low.Therefore influence the timely cleaning of sewer pipe, and make line clogging not smooth.

At present still not having a kind of desirable instrument can provide use, if adopt other mechanical means cleaning open caissons, has only design to do the both uneconomical flexible use that is not easy to like this with clearing up open caisson mud corresponding apparatus and power.

The purpose of this utility model is that a kind of light manpower grab bucket will be provided, and it can clear up the mud that accumulates in the sewer pipe open caisson effectively.

The purpose of this utility model is achieved in that being equipped with one in a loop bar can pull the pull bar that press rods promotes to stretch by manpower, grab bucket in the hinged symmetrical folding in the lower end of pull bar and loop bar, the open caisson bottom is put in grab bucket, stirred press rods, both realized the folding of grabbing bucket.

Therefore the utility model is because laborsaving when having adopted lever principle to operate, and structure is also simple, owing to adopted grab bucket, each mud that grasps is many and do not drop down, but straight cutting is gone into the clean of open caisson bottom cleaning.

The concrete structure of utility model is provided by following examples and accompanying drawing.

Fig. 1 is the utility model whole elevation of grabbing bucket.

Fig. 2 is the utility model grab bucket unitary side view.

Fig. 3 is the utility model grab bucket partial view.

Fig. 4 is the utility model grab bucket profile of tooth bucket bucket portion sectional view.

This grab bucket comprises the grab bucket (1) of a symmetrical folding, the pull bar (3) of an outer loop bar (2), a flexible push-and-pull grab bucket folding in loop bar (2), a press rods (4) that is hinged with rotating shaft (5) and pull bar upper end, one is connected between press rods (4) and the loop bar (2), and as the supporting arm (9) of pulling the fulcrum of press rods (4), all disjunctor is provided with lug (8) and is hinged with rotating shaft (6) in the hinged place of the fulcrum place of press rods (4) and loop bar (2) and supporting arm (9).A side is an opening in the lug top of loop bar (2), is convenient to pull press rods (4).In the lower end of loop bar (2) and pull bar (3), loop bar (2) is gone up disjunctor and is equipped with loop bar transverse axis (11) and has boss (13) to be connected.Lower end disjunctor at pull bar (3) is equipped with pull bar transverse axis (12), pull bar transverse axis (12) is hinged with the opening and closing place of grab bucket centering, and grab bucket (1) two side is corresponding hinged with loop bar transverse axis (11) with rotating shaft (7) by linking arm (10).

The insertion open caisson bottom this moment of the grab bucket (1) shown in figure one of will grabbing bucket when using the utility model is opening.Press rods (4) is pulled by subordinate, press rods (4) is fulcrum (6) rotation around the shaft from the opening part of loop bar (2) with supporting arm (9), and the pull bar (3) that press rods (4) resistance arm one end upwards lifts and spurs simultaneously in loop bar (2) cavity that is hinged with rotating shaft (5) moves upward.Pull bar (3) moves upward and has driven the grab bucket rotating shaft (7) on pull bar transverse axis (12) and linking arm (10) the simultaneously rotation that is hinged on the pull bar transverse axis (12), grab bucket is opened and closed finish the action of once grasping mud.Otherwise upwards pulling press rods (4) grab bucket opens.Therefore flexible operation is easy.

The structure of another kind of grab bucket (1) is to distinguish that around two of the grab bucket (1) of the symmetrical folding of pull bar transverse axis (12) the counterpart place disjunctor of body is provided with long tooth (14) one, there is a reinforcing rib (15) to increase the intensity of long tooth under every long tooth, the engagement that interlaces of two teeth of distinguishing body, the structure of this grab bucket (1) is favourable for the foreign material that grasp in the open caisson.

The utility model also can be used among the similar working environment.

Claims

1, a kind of light manpower grab bucket, the pull bar (3) that has loop bar (2) and in its cavity, stretch, having with supporting arm (9) is the press rods (4) that fulcrum one end is hinged with rotating shaft (5) and pull bar (3), has the grab bucket (1) that is installed in loop bar (2) and pull bar (3) lower end, the utility model is characterized in that: pull press rods (4), the upper end, making press rods (4) is that fulcrum rotates with supporting arm (9), and pushing drawing rod (3) at loop bar (2) thus flexiblely cavity in drive grab bucket (1) the realization folding that is hinged on loop bar (2) lower end loop bar transverse axis (11) and pull bar (3) the bottom end pulling bar transverse axis (12).
