Drawings
Fig. 1 is a schematic diagram of the present utility model.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.
Referring to fig. 1, a crane sling specially used for lifting a cement lining cast tube comprises a sling frame 10, wherein four movable pulleys 12 are fixed on the sling frame 10 and are used for being connected with a steel wire rope of a trolley, and two rigid guide posts 13 are fixed on the sling frame 10 to prevent a workpiece (the cement lining cast tube) from shaking in the running process.
Two slide ways 11 are fixed at two ends of the lifting tool frame 10, two clamps 20 are arranged at two ends of the lifting tool frame 10, each clamp 20 comprises two slide bars 28, the slide bars 28 are inserted into the slide ways 11 and can slide along the slide ways, and a supporting plate 21 is fixed at the bottom of each clamp 20.
Two L-shaped side guard plates 14 are arranged on the hanger frame 10, and the side guard plates 14 are arranged on the outer side of the slideway 11.
Four servo electric cylinders 30 are arranged on the lifting tool frame 10, one servo electric cylinder 30 is arranged at each slide 11, the cylinder body end of each servo electric cylinder 30 is fixed on the lifting tool frame 10, the moving end of each servo electric cylinder is fixed on the clamp 20, and power is provided for sliding of the sliding rod 28 in the slide 11.
To prevent the workpiece from rolling, the upper surface of the pallet 21 is a wave plate 22.
To achieve automation, each servo cylinder 30 is connected in parallel with a hard wire PLC via a communication bus.
In order to prevent the failure of the PLC from causing the servo cylinder to be unusable, a hanger 15 is attached to the hanger frame 10.
The specific working process is as follows:
first, during normal operation, couple 15 does not work, specifically:
s1, firstly, moving a crane lifting appliance (hereinafter referred to as lifting appliance) special for lifting the cement lining cast pipe to the upper part of a workpiece, so that the axis of the workpiece is consistent with the direction of a slideway 11, and two side guard plates 14 are positioned on two sides of the workpiece;
s2, the four servo cylinders 30 extend out to control the clamp 20 to move outwards until the supporting plate 21 avoids the end part of the workpiece;
s3, the lifting appliance continues to fall until the supporting plate 21 passes over the lower surface of the workpiece;
and S4, the four servo cylinders 30 are contracted, so that the clamp 20 is controlled to move inwards until the supporting plate 21 just supports the end part of the workpiece.
At this time, both end portions of the workpiece are supported by the pallet 21, and both side surfaces of the workpiece are blocked by the side guards 14, which is very safe.
When the servo electric cylinder cannot be used due to the failure of the second PLC, the hanger 15 is used for lifting, and meanwhile, the method is the same as the prior art and is not repeated.
The characteristics of the application:
(1): the upper part of the L-shaped bracket adopts a wave plate design, so that rolling of the cement lining cast tube in the movement process is effectively prevented.
(2): a mechanical anti-falling stop is arranged in the running direction, so that the cast tube falling caused by inertia in the acceleration/deceleration process is prevented.
(3): the double L-shaped bracket can be freely opened and closed, is compatible with cement lining cast pipes with various specifications, and can be suitable for lifting all cylindrical and strip-shaped sectional materials.
(4): and a double rigid guide post is adopted between the lifting appliance and the host machine, so that shaking in the running process is prevented.
(5): a special lifting hook is arranged under the lifting appliance, and the manual flexible strapping tape lifting can be carried out when the electric control is completely invalid.
(6): the redundant control and the driving host can be controlled by a bus and can be controlled by hard wires.
See the prior art for others.
The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
