Description

TECHNICAL FIELD

[0002] Section steel is a kind of strip steel material with certain cross-sectional shape and size, and is one of the four major varieties of steel (plate, pipe, section, wire). According to the cross-sectional shape, the section steel is divided into simple cross-section section steel and complex cross-section section steel (profiled steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc., and the latter refers to I-beam, channel steel, rail, window frame steel, curved section steel, etc. It is difficult to carry the steel structure frame assembled by section steel, which is prone to danger.

[0003] Chinese patent No. CN104908032B discloses an integrated manipulator structure, which comprises a manipulator body, a two-device carrying structure and a plugboard carrying structure. The manipulator body is provided with a connecting flange, a first mounting bracket and a second mounting bracket. The connecting flange is arranged at the uppermost part of the manipulator body, and the second mounting bracket is arranged on one side of the first mounting bracket. The manipulator body is connected with a robot through the connecting flange. The two-device carrying structure is installed on the manipulator body through the first mounting bracket. The plugboard carrying structure is installed on the manipulator body through the second mounting bracket. This scheme uses an integrated manipulator structure to complete two-device carrying and plugboard carrying at the same time. The manual process is replaced by automatic operation, which reduces the labor intensity of workers, improves the working environment of workers and improves the carrying efficiency.

[0040] In use, first, the mobile frame 1 is moved to the upper end of the steel structure frame to be carried, the lifting motor 4 is started to drive the lifting threaded rod 5 to rotate, the lifting column 6 slides downward in the guide sleeve 3, the lifting platform 10 and the lifting clamping jaw 8 and the limiting angle clamping jaw 12 are lowered, the lifting clamping jaw 8 and the limiting angle clamping jaw 12 are lowered to the inner side of the steel structure frame, the angle motor 13 is started to drive the lifting push plate 14 to rotate, the lifting push plate 14 rotates to push the push bar 151, and the push bar 151 is pushed and lifted over the blocking key 112 of the angle column 11, the clamping push rod 15 pushes the limiting angle clamping jaw 12 to rotate and open on the surface of the angle column 11, the blocking key 112 in the movable slot 111 of the angle column 11 blocks the reverse sliding of the clamping push rod 15, until the limiting angle clamping jaw 12 is opened to a suitable angle, the limiting angle clamping jaw 12 extends to block the falling of the steel structure frame, the second hydraulic rod 73 is started to change the distance between the adjusting platform 74 and the lifting platform 71, so that the second lifting rod 93 changes the height of the adjusting ring 91 on the surface of the lifting column 6, the bending finger 82 is pushed open by the push-pull connecting rod 92, the lifting motor 4 is started to drive the lifting column 6 to rise, and the lifting clamping jaw 8 and the limiting angle clamping jaw 12 are clamped on the inner side of the steel structure frame, so that the steel structure frame is lifted up as the lifting column 6 rises.

[0041] When the steel structure frame is lifted up and needs to adjust the grabbing position, the first hydraulic rod 72 is started to drive the lifting platform 71 to approach the positioning plate 62, and the lifting platform 71 drives the lifting finger sleeve 81 to rise along the lifting column 6 by the first lifting rod 83, so that the bending finger 82 hooks the steel structure frame to rise, and the steel structure frame continues to rise by a distance on the basis of the original position, and at the same time, the lifting push plate 14 keeps the state of lifting the push bar 151 to prevent the push bar 151 from being clamped with the blocking key 112, and when the clamping push rod 15 is not blocked, the limiting angle clamping jaw 12 is retracted by its own gravity on the clamping push rod 15 to prevent the limiting angle clamping jaw 12 from being opened to block the rising steel structure frame, and the steel structure frame is lifted to the desired position, and the limiting angle clamping jaw 12 is opened again to support the steel structure frame, and the lifting clamping jaw 8 is reset, and if the steel structure frame needs to be lifted again, the above actions are repeated to gradually lift the steel structure frame.
