The upper fixing plate 111 and the lower fixing plate 112 have the same structure.
With reference to fig. 2, the above structures of the fixing plate 111 and the mounting plate 11 are specifically described in this embodiment. A vertical sliding groove is formed in the mounting plate 11, a vertical screw rod is mounted on the groove wall of the sliding groove, and a hand wheel is welded at the top of the screw rod. The upper fixing plate 111 is slidably mounted on the inner wall of the chute, and the upper fixing plate 111 is in threaded fit with the screw. Two sections of threads with opposite directions are arranged on the upper section and the lower section of the screw, when a worker rotates the hand wheel, the screw can drive the upper fixing plate 111 and the lower fixing plate 112 to synchronously move in opposite directions or opposite directions, and the worker can adjust the distance between the upper clamping assembly 12 and the lower clamping assembly 13 and the duct piece by rotating the screw.
Referring to fig. 3, the upper clamping assembly 12 and the lower clamping assembly 13 are provided with a plurality of groups, in this embodiment, three groups are specifically described as examples, and the three groups of upper clamping assemblies 12 and lower clamping assemblies 13 are respectively uniformly distributed on the upper fixing plate 111 and the lower fixing plate 112. The upper fixing plate 111 is provided with a screw hole, and the upper clamping assembly 12 includes a lifting rod 121 vertically arranged and screw-mounted in the screw hole, and a contact seat 122 hinged to the bottom end of the lifting rod 121 by using a hinge seat. A rubber mount is adhered to the lower surface of the contact mount 122. A force nut 123 having a regular hexagonal cross section is welded to the top of the lifting rod 121.
When a worker clamps a pipe piece, a spanner is sleeved on the force application nut 123, the spanner is used for rotating the lifting rod 121, and under the action of threads, the lifting rod 121 pushes the rubber seat on the lower surface of the contact seat 122, so that the rubber seat is abutted on the upper surface of the pipe piece. Under the pushing of the lifting rod 121, the contact seat 122 is pressed against the rubber pad 124 for a certain time, so that the rubber pad 124 is elastically deformed, and the contact area between the rubber pad 124 and the duct piece is increased.
Referring to fig. 4, a mounting lug is welded on a side of the top of the mounting plate 11 away from the upper clamping assembly 12, a vertical mounting hole is formed in the mounting lug, and the connection mechanism 2 is rotatably mounted in the mounting hole. The connection mechanism 2 includes a hook 21 rotatably installed at the bottom inside the hole, a drop-preventing lever 22 hinged on the tail of the hook 21, and a spring 23 provided between the hook 21 and the drop-preventing lever 22.

The implementation principle of the suspender anti-slip device for vertical pipe piece hoisting is as follows: after the pipe piece is placed by a worker, the heights of the upper clamping assembly 12 and the lower clamping assembly 13 are adjusted by rotating the screw rod by a hand wheel, so that the upper clamping assembly 12 and the lower clamping assembly 13 are approximately close to the upper surface and the lower surface of the pipe piece, and then the worker rotates the lifting rod 121 by using a spanner to finely adjust the height of the contact seat 122, so that the rubber seat is abutted on the surface of the pipe piece. Under the pressure applied by the contact seat 122, the rubber pad 124 deforms, so that the contact area between the rubber pad 124 and the duct piece is increased, and the stability of the clamping ground of the upper clamping assembly 12 and the lower clamping assembly 13 is improved. After the upper clamp assembly 12 and the lower clamp assembly 13 are installed, the worker installs the harness on the hanger 21.
