Abstract

The utility model relates to the technical field of machinery, in particular to a tower crane with an improved griper, which comprises a beam, a griper, a bracket and a rotating shaft and is characterized in that the rotating shaft is arranged below the outer side of the griper, the bracket is connected to the rotating shaft in shaft connection mode, and the bracket is formed by vertically connecting a V-shaped frame to the bottom end of the extensible rod. Compared with the prior art, the bracket is added, thereby enabling materials to be more stable during the process the materials are grabbed and improving safety.

Description

A kind of tower crane that improves the pawl bucket
Technical field
The utility model relates to field of mechanical technique, specifically a kind of tower crane that improves the pawl bucket.
Background technology
When generally on the building ground, grabbing heavy construction materials such as hanging cement plate, the left and right sides two halves of the pawl bucket of tower crane are directly clamped the cement plate outer wall, and its bottom is unsettled, does not have support, because volume of material is bigger, weight is very big, causes potential safety hazard easily.
Summary of the invention
The utility model is the deficiency that overcomes prior art, is provided with carriage at the outer side-lower of pawl bucket, makes in the process of material grasping and can stablize material.
For realizing above-mentioned purpose; Design a kind of tower crane that improves the pawl bucket, comprise crossbeam, pawl bucket, carriage, rotating shaft, it is characterized in that: the outer side-lower of pawl bucket is provided with rotating shaft; The carriage that is coupling in the rotating shaft, described carriage vertically connects wishbone by the bottom that is employed in expansion link and is formed.
Rotating shaft and carriage are provided with 2 at least.
The utility model is compared with prior art, has increased carriage, makes material more stable in crawled process, has improved safety.
Description of drawings
Fig. 1 is the scheme drawing of the utility model structure.
Fig. 2 is the initial condition figure of the utility model.
Fig. 3 is the amplification inclinating view of carriage.
Referring to Fig. 1, Fig. 2,1 is crossbeam, and 2 is the pawl bucket, and 3 is expansion link, and 4 are rotating shaft, 5 is wishbone.
The specific embodiment
According to accompanying drawing the utility model is done explanation further below.
Like Fig. 1, shown in Figure 2, design a carriage, this carriage is that an end that is employed in expansion link 3 vertically connects 5 compositions of wishbone.
Pawl bucket 2 down either side are established a rotating shaft 4 respectively, and the other end of the expansion link 3 that is coupling in the rotating shaft 4 is not when pawl bucket 2 is worked; Expansion link 3 is fitted in pawl bucket 2 lateral walls, and after pawl bucket 2 grasped material, the tower crane operator controlled pawl bucket 2 earlier and promotes slightly; And then set rotating shaft 4 rotations in control pawl bucket 2 outsides, thereby make expansion link 3 around axle 4 rotations, control expansion link 3 then and upwards shrink again till wishbone props up the material bottom to suitable length; And then lifting material; Like this in the process that grasps owing to set up carriage, make material more firm in the process that grasps, improved safety.

Claims (2)
