[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 6 As shown, the portable assembled high-altitude work protection device of this embodiment includes a clamp 1, a base 2, a vertical rod 3 and a high-altitude fall arrester. The clamp 1 is fixed to the outer periphery of the substation structure 5, and the outer wall of one end of the clamp 1 is fixed to one end of the base 2; a through hole 21 is opened on one side wall of the base 2, and a mounting groove 22 is opened on the top of the base 2, and the through hole 21 is connected with the mounting groove 22; the bottom of the vertical rod 3 is arranged inside the mounting groove 22; a mounting hole is opened on the side wall of the vertical rod 3, and bolts pass through the through hole 21 and the mounting hole in sequence and are fixed with the through hole 21 and the mounting hole; a hanging ring 31 is fixed on the side wall of the vertical rod 3, and the high-altitude fall arrester is rotatably connected with the hanging ring 31.

[0027] The utility model uses the base 2, the vertical rod 3 and the high-altitude fall arrester to set up a construction device beside the power transformation structure 5, so that construction workers can adjust the height of the safety belt safely and conveniently.

[0028] Furthermore, the other end of the clamp 1 is fixed to the additional fastener 11, and the additional fastener 11 is fixed to the switch cabinet.

[0029] The device is connected to a switch cabinet (not shown) by means of additional fasteners 11, so as to be suitable for the construction of the switch cabinet.

[0030] Furthermore, a plurality of vertical rods 3 are provided, and flanges 32 are fixed between adjacent vertical rods 3 .

[0031] According to the height required for construction, a corresponding number of vertical rods 3 are connected.

[0032] Furthermore, a foot nail 33 is fixed in the mounting hole above the base 2 .

[0033] The foot nails 33 are provided for construction workers to move up and down.

[0034] Furthermore, the material of the vertical rod 3 is a steel pipe or a glass fiber reinforced plastic pipe.

[0035] Furthermore, the high-altitude fall arrester includes a U-bolt 41, a T-connector 42 and a speed differential fall arrester 43, the arc end of the U-bolt 41 is rotatably connected to the hanging ring 31, the open end of the U-bolt 41 is fixed to one end of the T-connector 42, the other end of the T-connector 42 is rotatably connected to one end of the speed differential fall arrester 43, and the other end of the speed differential fall arrester 43 is fixed to the safety belt.

[0036] Through this structure, the high-altitude fall arrester ensures that construction workers will not fall while giving them a certain range of activities.

[0037] Furthermore, the substation structure 5 is a support cement pole or steel pipe or a main transformer riser or a GIS vertical component.

[0038] For main transformer maintenance, the operator can use the clamp 1 to fasten it to the main transformer lifting base, and then fix the vertical rod 3 on the base 2. The base 2 is connected to the clamp 1 by bolts. At this time, the height of the vertical rod 3 can be set to about 2m. After the operator connects the safety belt to the speed differential anti-fall device 43, the speed differential anti-fall device 43 is fixed to the hanging ring 31 of the vertical rod 3 through the U-bolt 41 and the T-type connector 42 to complete the installation of the entire device.

[0039] For GIS equipment and brackets, since their main body height is relatively high, usually up to 2.5m, the safety belt hanging position should generally be considered to be at least 4-5m high, that is, the height of the vertical rod 3 should reach 4-5m. At this time, another vertical rod 3 can be connected through the flange 32 to provide a high hanging point.

[0040] For a decentralized switch cabinet, additional fasteners 11 may be further provided outside the clamp 1 to achieve fixation with the switch cabinet.

[0041] The method of using the utility model is:

[0042] 1. Install the clamp 1 on the substation structure 5. Rubber gaskets can be appropriately added inside the clamp 1 to protect the equipment body.

[0043] 2. Connect the base 2 and the clamp 1 with bolts.

[0044] 3. Insert the vertical rod 3 into the base 2, and limit the vertical rod 3 by inserting bolts.

[0045] 4. Foot spikes 33 are arranged around the vertical pole 3, and personnel can climb upward through the foot spikes 33. Hanging rings 31 are arranged every 2 meters on the vertical pole 3. When climbing, the safety belt can be hung on the upper hanging ring 31 until it meets the working requirements.

[0046] 5. To install the high-altitude fall arrester, the operator first connects the safety belt to the speed differential fall arrester 43, then connects the speed differential fall arrester 43 to the T-shaped connector 42, and finally hangs the T-shaped connector 42 and the U-shaped bolt 41 on the hanging ring 31 and connects them with screws.

[0047] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
