Description

Technical Field

[0001] The utility model relates to the technical field of vacuum suction cup transmission, in particular to a protective device for a vacuum suction cup used for pipe segment processing. Background Art

[0002] The vacuum cup relies on the suction force of the vacuum chamber to attach to the surface of the pipe segment to form a vacuum, thereby sucking the pipe segment and lifting it. Since the vacuum cup relies on the close fit between the cup and the pipe segment to form a vacuum, the surface of the pipe segment needs to be very smooth and no unevenness is allowed. The vacuum cup also requires a vacuum pump to control the suction force of the storage tank through a one-way valve and maintain the vacuum degree of the storage tank at or above 80%.

[0003] However, if the vacuum degree does not reach this value, it indicates that there is a leak in the suction circuit. The pipeline between the storage tank and the vacuum pump must be checked, and the seal on the filter must also be checked. The existence of these problems may easily lead to the possibility of the pipe segment falling. Therefore, the present application proposes a protective device for the vacuum suction cup used in pipe segment processing to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a protective device for a vacuum suction cup used for pipe segment processing, which has the advantages of preventing the pipe segment from falling off, and solves the problem that the vacuum degree fails to reach 80%, which easily causes the pipe segment to fall off.

[0006] The protection mechanism includes a safety arm hinged on the left side of the load frame through an articulated shaft, a cylinder is hinged on the left side of the load column through an articulated shaft, a connecting rod is fixed on the outer side of the cylinder output shaft, and the left end of the connecting rod is hinged to the articulated frame through the articulated shaft.

[0007] Furthermore, a pipe segment body is provided below the load frame, and the pipe segment body is movably attached to the lower surfaces of the three vacuum suction cup bodies.

[0008] The beneficial effect of adopting the above further solution is that the plurality of vacuum suction cup bodies rely on the suction force of the vacuum chamber to adhere to the upper surface of the tube segment body and form a vacuum, thereby sucking the tube segment body.

[0009] Furthermore, the cross-sectional shape of the safety arm is a U-shaped plate, and a rubber pad is fixed to the bottom wall of the inner cavity of the safety arm.

[0010] The beneficial effect of adopting the above further solution is: using rubber pads to protect the pipe segment body, thereby avoiding the problem of wear and tear on the pipe segment body.

[0011] Furthermore, the shape of the articulated frame is an inverted U-shaped U-shaped plate.

[0012] Furthermore, the lower right end of the articulated frame is hinged to the front and rear sides of the load frame through an articulated shaft.

[0013] Furthermore, the lower left end of the articulated frame is hinged to the outer side of the safety arm through a hinge shaft.

[0014] The beneficial effect of adopting the above further scheme is: by starting the left and right cylinders, the left and right articulated frames begin to drive the left and right safety arms to begin to flip downward, so that the left and right safety arms contact the lower surface of the pipe segment body.

[0015] Furthermore, the number of the protection mechanisms is two, and the two protection mechanisms are symmetrically distributed with respect to each other on the left and right sides with the central axis of the load frame as the symmetry line.

[0016] The beneficial effect of adopting the above further solution is that protection mechanisms are provided on the left and right sides to support and stabilize the main body of the segment.

[0017] Furthermore, the segment body is located between two safety arms.

[0018] The beneficial effect of adopting the above further solution is that the main body of the segment is supported and protected by the safety arms on the left and right sides.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] The protective device of the vacuum suction cup used for pipe segment processing relies on the suction force of the vacuum chamber to attach to the upper surface of the pipe segment body and form a vacuum, thereby sucking the pipe segment body. By starting the left and right cylinders, the left and right articulated frames begin to drive the left and right safety arms to start flipping downward, so that the left and right safety arms contact the lower surface of the pipe segment body, and use rubber pads to protect the pipe segment body to avoid wear and tear of the pipe segment body.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In this embodiment, a segment body 5 is provided under the load frame 1. The segment body 5 is movably fitted to the lower surfaces of three vacuum suction cup bodies 4. The segment body 5 is located between two safety arms 201. Multiple vacuum suction cup bodies 4 rely on the suction force of the vacuum chamber to adhere to the upper surface of the segment body 5 and form a vacuum, thereby sucking the segment body 5, and then the segment body 5 is lifted by an external crane or other device.

[0028] See also Figure 3 In order to protect the segment body 5, the protection mechanism 2 in this embodiment includes a safety arm 201 hinged to the left side of the load frame 1 through a hinge shaft, a cylinder 203 is hinged to the left side of the load column 6 through a hinge shaft, a connecting rod 204 is fixed to the outer side of the output shaft of the cylinder 203, and the left end of the connecting rod 204 is hinged to an articulated frame 205 through a hinge shaft.

The cross-sectional shape of the safety arm 201 is a U-shaped plate. A rubber pad 202 is fixed to the bottom wall of the inner cavity of the safety arm 201. The rubber pad 202 is used to protect the pipe segment body 5 to avoid wear of the pipe segment body 5. The shape of the articulated frame 205 is an inverted U-shaped U-shaped plate. The lower right end of the articulated frame 205 is hinged to the front and rear sides of the load frame 1 through a hinge shaft. When the pipe segment body 5 is vacuum-adsorbed, in order to prevent the pipe segment body 5 from falling, the left and right cylinders 203 are started at this time, so that the left and right articulated frames 205 start to drive the left and right safety arms 201 to start to flip downward, so that the left and right safety arms 201 contact the lower surface of the pipe segment body 5 to support the lower surface of the pipe segment body 5, and the lower left end of the articulated frame 205 is hinged to the outside of the safety arm 201 through a hinge shaft.

[0030] It should be noted that, by relying on the suction force of the vacuum chamber, multiple vacuum suction cup bodies 4 are attached to the upper surface of the pipe segment body 5 and form a vacuum, thereby sucking the pipe segment body 5, and by starting the left and right cylinders 203, the left and right articulated frames 205 begin to drive the left and right safety arms 201 to begin to flip downward, so that the left and right safety arms 201 are in contact with the lower surface of the pipe segment body 5, and the rubber pads 202 are used to protect the pipe segment body 5 to avoid wear and tear of the pipe segment body 5.

[0032] The working principle of the above embodiment is:

[0033] When it is necessary to use the vacuum suction cup protection device for segment processing, multiple vacuum suction cup bodies 4 rely on the suction force of the vacuum chamber to adhere to the upper surface of the segment body 5 and form a vacuum, thereby sucking the segment body 5, and then lifting the segment body 5 by an external crane or other device. When the segment body 5 is vacuum-adsorbed, in order to prevent the segment body 5 from falling, the left and right side cylinders 203 are started at this time, so that the left and right side articulated frames 205 begin to drive the left and right side safety arms 201 to start flipping downward, so that the left and right side safety arms 201 are in contact with the lower surface of the segment body 5, and the rubber pads 202 are used to protect the segment body 5 to avoid wear of the segment body 5.
