Problems solved by technology

If it is wrong, it is not efficient, or it cannot be used.
[0003] my country's traditional grab has been in use for nearly 60 years. Although there have been great improvements and changes in the 1960s and 1970s, these improvements and innovations are limited to structural and situational innovations and improvements, and their working principles are not The fundamental change is that when the grab is retrieving materials, the opening and closing bucket wire rope rises to gradually close the bucket opening. In order to ensure that the bucket is full, the closing time must be extended so that the grab can go down by its own weight during the retrieving process. Shen, this is the only way to ensure that the bucket is filled with materials

Embodiment

[0015] -A kind of grab, such as figure 1 As shown, the grab bucket body 6 is included. The upper end of the grab bucket body 6 is provided with an opening and closing bucket speed controller 1 which is linked with the crane lifting speed controller 2.

[0016] The opening and closing bucket speed controller 1 controls the speed of the opening and closing bucket to be 1 / 3 to 1 / 4 of the crane hoisting speed controlled by the crane hoisting speed controller 2.

[0017] The upper end of the grab bucket body 6 is provided with a bolster 3, and the opening and closing bucket speed controller 1 is provided on the bolster 3.

[0018] The grab bucket body 6 is divided into a left bucket body 61 and a right bucket body 62. The left bucket body 61 and the right bucket body 62 are connected with two left and right support rods 5, and the upper ends of the left and right two support rods 5 pass through the rotating shaft 4 Connected to the bolster 3, the support rod 5 expands outward or closes i...

Abstract

The invention belongs to the technical field of lifting appliances, and relates to a grab bucket, in particular to a grab bucket without a pulley block and a bucket opening and closing steel wire rope. The grab bucket comprises a grab bucket body (6), a bucket opening and closing speed controller (1) is arranged at the upper end of the grab bucket body (6) and is linked with a crane lifting speed controller (2), and the bucket opening and closing speed is set to be 1 / 4 to 1 / 3 of the crane lifting speed. The grab bucket overcomes the defect that in the prior art, the aim of deceleration can only be achieved with the help of the pulley block and the bucket opening and closing steel wire rope; the grab bucket without the pulley block and the bucket opening and closing steel wire rope is provided; in the bucket opening and closing process, the structure is simple, the manufacturing cost is low, the weight is small, the bucket volume is large, maintenance is simple, the service life is long, and the working efficiency is high. The grab bucket has a good application prospect in the technical field of the lifting appliances.

Description

Technical field [0001] The present invention belongs to the technical field of spreaders, and relates to a grab bucket, in particular to a grab bucket without a pulley block and a steel wire rope for an opening and closing bucket. Background technique [0002] The grab bucket is a bucket that can be opened and closed for grabbing mud and various bulk goods. It is a spreader that grabs and discharges bulk materials by opening and closing two combined buckets or multiple jaws. The grab is a fetching device under the crane, so even the most advanced grab can not do the work without the crane. On the contrary, no matter how advanced, no matter how large the tonnage of the ship unloader is, it is inseparable from the grab to have production efficiency. Therefore, what kind of crane should be equipped with what kind of grab, it can not be used if it is equipped with a wrong one, and it cannot be used if it is equipped with a large overload. Grab is used for loading and unloading vari...
