[0032] The U-shaped sheath 13 is sleeved on the outer side of the supporting plate 8 and the clamping plate 9, and is used for protecting the supporting plate 8 and the clamping plate 9. The U-shaped sheath 13 is designed in a quick release mode. When the U-shaped sheath 13 needs to be replaced due to deformation, the fixing of the U-shaped sheath 13 by the locking pin structure can be released, so that the U-shaped sheath 13 is convenient to maintain, and the service life of the supporting plate 8 and the clamping plate 9 is longer.

[0033] It is worth further explaining that the lower end of the hanger 1 is provided with two limiting cylinders 2, the limiting cylinders 2 are fixedly connected with the hanger 1, two adjusting columns 3 are respectively inserted into the two limiting cylinders 2, the adjusting columns 3 are slidingly connected with the limiting cylinders 2, the upper end of the limiting cylinder 2 is provided with two first hydraulic rods 4, the mounting end of the first hydraulic rod 4 is fixedly connected with the limiting cylinder 2, and the output end of the first hydraulic rod 4 is movably connected at the end of the adjusting column 3 away from the limiting cylinder 2.

[0035] Regarding the locking pin structure:

[0036] The locking pin structure comprises push-pull plates 16 arranged on the left and right sides of the U-shaped sheath 13. The side of the push-pull plate 16 facing the U-shaped sheath 13 is provided with at least two pin rods 15, and the pin rods 15 are fixedly connected with the push-pull plate 16. The left and right sides of the U-shaped sheath 13 are provided with through holes matched with the pin rods 15, and the outer sides of the clamping plate 9 and the supporting plate 8 are provided with positioning holes 12 matched with the pin rods 15. After the U-shaped sheath 13 is sleeved on the outer sides of the supporting plate 8 and the clamping plate 9, when the through holes on the U-shaped sheath 13 are in a coinciding state with the positioning holes 12 on the outer sides of the supporting plate 8 and the clamping plate 9, the push-pull plate 16 on the outer side of the U-shaped sheath 13 is pushed, the pin rods 15 on the push-pull plate 16 are inserted into the positioning holes 12 from the through holes, the pin rods 15 are fixed on the outer sides of the supporting plate 8 and the clamping plate 9 by cooperating with the positioning holes 12, and the U-shaped sheath 13 is flexible to replace.

[0037] In order to enable the push-pull plate 16 to be attached to the left and right sides of the U-shaped sheath 13, and the pin rods 15 arranged in the through holes not to automatically fall out of the through holes, the side of the U-shaped sheath 13 facing the push-pull plate 16 is provided with a spring groove 18, the spring groove 18 is provided with a spring 19, the spring 19 is fixedly connected with the U-shaped sheath 13, and the end of the spring 19 away from the U-shaped sheath 13 is fixedly connected with the push-pull plate 16. When the push-pull plate 16 is pulled outward, the spring 19 will be unfolded, the pin rods 15 will slide into the through holes from the positioning holes 12, and after the push-pull plate 16 is released, the push-pull plate 16 will keep close to the U-shaped sheath 13 under the pulling of the spring 19, and the pin rods 15 will be reset.

[0038] In order to facilitate the staff to pull the push-pull plate 16, the pin rod 15 is separated from the positioning hole 12, in the preferred scheme, the push-pull plate 16 is provided with a handle 17 away from the U-shaped sheath 13 side, the handle 17 is fixedly connected to the center of the push-pull plate 16. When the pin rod 15 is released from the limiting of the supporting plate 8 and the clamping plate 9, the push-pull plate 16 is horizontally pulled out by holding the handle 17.

[0039] Regarding the lifting assembly:

[0040] The lifting assembly comprises a second hydraulic rod 11, the second hydraulic rod 11 is fixedly connected to the upper end of the sleeve frame 6, and the output end of the second hydraulic rod 11 is fixedly connected to the upper end of the clamping plate 9. The lifting of the clamping plate 9 is controlled by the second hydraulic rod 11, of course, in addition to using the second hydraulic rod 11 to control the lifting of the clamping plate 9, a linear pushing mechanism such as an electric push rod or a hydraulic push rod can also be used as an alternative, which will not be described here.

When the clamping plate 9 is lowered in the sleeve frame 6 to fix the guardrail to be hoisted, the sliding blocks 10 fixed to the two ends of the clamping plate 9 will slide along the sliding grooves 7 opened on the side edges of the sleeve frame 6, and the sliding grooves 7 will limit the clamping plate 9 from both ends of the clamping plate 9 through cooperation with the sliding blocks 10, to ensure that the clamping plate 9 remains stable during adjustment.

[0042] Working principle of the present application:

[0043] When hoisting the guardrail, the first hydraulic rod 4 pushes the adjusting column 3, the adjusting column 3 slides along the inner side wall of the limiting cylinder 2, adjusts the distance between the two fixing seats 5, and makes the two sleeve frames 6 open. The operating personnel need to place the assembled guardrail between the two sleeve frames 6, and the sleeve frame 6 limits the guardrail from both ends. The lifting assembly pushes the clamping plate 9 to fall, and the clamping plate 9 is fixed between the supporting plate 8 and the clamping plate 9 after falling. The U-shaped sheath 13 is clamped outside the supporting plate 8 and the clamping plate 9, which is used to protect the supporting plate 8 and the clamping plate 9. The U-shaped sheath 13 adopts quick-release design, when the U-shaped sheath 13 needs to be replaced due to deformation, the fixing of the U-shaped sheath 13 by the locking pin structure is released, the U-shaped sheath 13 is convenient to maintain, and the service life of the supporting plate 8 and the clamping plate 9 is improved.
