The clamping means comprise a first clamping plate 7, a second clamping plate 12, guiding means and locking means. The head end of the first clamping plate 7 is connected with the connecting base 3, the tail end of the first clamping plate 7 is provided with a first bayonet 9, and the tail end of the second clamping plate 12 is provided with a second bayonet 13. The first bayonet 9 and the second bayonet 13 are located on the same axis and are suitable for being sleeved on one group of fasteners of the flange 8 of the GIS equipment, and thus the two clamping devices are respectively clamped on the two groups of fasteners of the flange 8. The orientation of the guide means is parallel to the axis between the first bayonet 9 and the second bayonet 13, and the locking means causes the second clamping plate 12 to perform a clamping action towards the first clamping plate 7 under the action of the guide means.

The device needs to be installed on the flange 8 of GIS equipment when in use, because the GIS equipment is sealed with insulating gas, a plurality of flanges 8 can exist in the whole set of GIS equipment, so that a proper installation place can be conveniently found, and the device has higher universality. During installation, the first clamping plate 7 and the second clamping plate 12 are firstly opened and then are mutually far away from each other, the distance between the two clamping plates is larger than the length of a bolt on the flange 8, then the opened first clamping plate 7 and the second clamping plate 12 are inserted into two sides of the flange 8, the first clamping opening 9 and the second clamping opening 13 of the same clamping device are aligned to the same group of fasteners, then the first clamping plate 7 and the second clamping plate 12 are folded and clamped through the locking device, and the first clamping opening 9 and the second clamping opening 13 are finally clamped on the bolt head or the nut. Because the upper and lower sets of clamping devices clamp the two different bolt groups of the flange plate 8 respectively, a triangular connection relationship is formed between the two different bolt groups and the connection base 3 when seen in the front view direction of fig. 1, so that the connection base 3 obtains higher stability and provides stable support for the safety belt hanging ring 1 above. In the side view direction, the first clamping plate 7 and the second clamping plate 12 are spanned on two sides of the flange plate 8, and are tightened and locked through the locking device, so that the two clamping plates are not separated at will, firm support is provided for the connecting base 3, the connecting base 3 is enabled to be subjected to lateral force and not to overturn, the stability of the whole device is guaranteed, and the personal safety of a falling person is guaranteed even if the falling accident occurs.

The slide bar 5 and the sliding sleeve 11 are convenient to process, and the guiding device is arranged at the head end of the clamping plate, so that the guiding device can interfere with the flange 8 when the two clamping plates are spanned on the flange 8, and meanwhile, the connection and guiding problems of a spanned structure are solved, so that the structure of the whole device is more reasonable.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 1, after the upper and lower sets of clamping devices are both clamped, that is, when the whole device is in an operating state, the outer side surface of the sliding sleeve 11 of each set of clamping device abuts against the outer edge of the flange 8 of the GIS device. After the sliding sleeve 11 is propped against the flange 8, a limiting relation is formed, so that the whole fixing structure can be more stable, the extrusion force of the sliding sleeve 11 and the flange 8 can also share the lateral force applied by the two bayonets to the bolt group, and the problem that the bolt group is bent after being subjected to the too strong lateral force is avoided.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 1, the mating parts of the sliding rod 5 and the sliding sleeve 11 are circular in cross section, and the guiding device further comprises a key 6; the key 6 is connected between the slide bar 5 and the slide bush 11 and prevents rotation between the slide bar 5 and the slide bush 11. The shaft and the sleeve with the circular section are easier to process, but the problem of relative rotation can be caused, so that the guide device of the device is further provided with the key 6 to prevent rotation, thereby ensuring that the first bayonet 9 and the second bayonet 13 can always keep a coaxial relationship, and the bayonet on the other side can be self-aligned after one bayonet is aligned with the fastener, thereby improving the installation operation efficiency.

In another preferred embodiment, the mating parts of both the slide bar 5 and the slide bush 11 may also be square in cross section. The square section shaft and sleeve are more complex than round processing, but still relatively easy to process, and the square section directly provides the function of preventing rotation, so that the number of parts of the device can be reduced, and the assembly efficiency can be improved.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 3, the locking device comprises an adjusting bolt 10, and the adjusting bolt 10 is threaded with the second clamping plate 12 after penetrating the first clamping plate 7. The adjusting bolt 10 is used as a locking device, so that the operation is simple and quick, and a high enough clamping force can be provided only by a common wrench, and the danger of loosening and the like of the device is avoided.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 3, a first support arm 15 is disposed on the sliding sleeve 11 located at the head end of the first clamping plate 7, a second support arm 14 is disposed on the side wall of the connection base 3, and the first support arm 15 and the second support arm 14 are rotatably connected through the rotating shaft 4. The axis of the rotary shaft 4 is parallel to the axis between the first bayonet 9 and the second bayonet 13. After the rotating shaft 4 is arranged, the two sets of clamping devices can move in an opening-closing mode, so that the bayonet distance between the two sets of clamping devices can be adjusted to adapt to flanges 8 with different diameters or different bolt group spans, and the adaptability of the device is improved.

In a preferred embodiment, based on the above embodiment, as shown in fig. 1, the first bayonet 9 and the second bayonet 13 are circular holes. Although the most suitable shape of the bayonet is hexagonal with the same size as the corresponding bolt head or nut, the corners of the bolt and the nut after being fastened are not unified, and the bayonet has extremely high randomness, so that the bayonet is used as a round hole and is only sleeved outside the fastener in order to adapt to fasteners with different corners, thereby not only providing a clamping function, but also ensuring adaptability.

It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present utility model.
