A rotatable and direction-changing box grab

Abstract

The invention relates to a rotatable turning box grab bucket. The rotatable turning box grab bucket comprises a fixed plate, four electric slide rails, four mechanical claws and a rotary turning device, wherein the four electric slide rails are respectively located on the four vertex angle bisectors of the fixed plate; the four mechanical claws are respectively mounted under the four electric slide rails; the rotary turning device is located right above the fixed plate and comprises a lower disc, an upper disc, balls, reinforcing ribs and a rotary motor; the upper disc adopts a disc-shaped structure; a ring-shaped groove is formed in the bottom end surface of the upper disc in the circumferential direction; 36 balls are uniformly mounted in the ring-shaped groove in the bottom end surface of the upper disc along the central axis of the upper disc; the main shaft of the rotary motor penetrates the middle of the upper disc to be connected with the lower disc; the rotary motor is fixed to the upper disc through a motor seat. The rotatable turning box grab bucket can achieve the rotary turning function in the article grabbing process to take the 360-degree adjusting effect, thereby facilitating adjustment of the article hoisting, grabbing and placing positions.

Description

technical field [0001] The invention relates to the field of grabbing equipment, in particular to a rotatable direction-changing box grab. Background technique [0002] The grab bucket is a bucket that can be opened and closed by grabbing sand, gravel and various bulk goods. It is a spreader that mainly relies on the opening and closing of two combined buckets on the left and right or multiple jaw plates to grab and discharge bulk materials. According to the classification of the shape, the grab can be divided into a shell-shaped grab and a orange-shaped grab. The former is composed of two complete buckets, and the latter is composed of three or more jaw plates; according to the driving method, it can be divided into hydraulic There are two types of grabs and mechanical grabs.

Problems solved by technology

[0003] With the development of modern logistics, the transportation of goods is more and more developed. Now the goods are mostly loaded in boxes, and for large cargo equipment, they are loaded in containers. Therefore, in ports, transportation stations, and some free trade zones, containers are used. There are a lot of body handling every day. At present, manual handling is used for small box handling, forklifts are mostly used for large box handling, and grabs and cranes are used for container handling. There is no professional grab for the existing box handling and lifting. , the claw-type grab is commonly used. This kind of grab will cause great damage to the outside of the box, and sometimes even damage the items inside the box. It is carried out by crane, which is very inconvenient when placing items
