Detailed Description

Exemplary embodiments that embody features and advantages of the present invention will be described in detail in the following description. It is to be understood that the invention is capable of other and different embodiments and its several details are capable of modification without departing from the scope of the invention, and that the description and drawings are to be regarded as illustrative in nature and not as restrictive.

Referring to fig. 3 and 4, the movable platform provided in this embodiment is used for overlapping a deck platform 600 and a pile leg 100, and includes a hollow stop collar 1 fixed on the deck platform 600, an extension plate 2 slidably inserted into the stop collar 1 and having two ends extending out of the stop collar 1, and a first thrust block 3 disposed at one end of the extension plate 2 away from the pile leg 100. When the extension plate 2 extends out from the stop collar 1 towards the pile leg 100, the first thrust block 3 can abut against the end surface of the stop collar 1.

The lap joint between the deck platform 600 and the leg 100 is achieved by extending the extension plates 2 in the stop collar 1 towards the leg 100. Meanwhile, the limiting sleeve 1 can prevent the extension plate 2 from generating left and right displacement and tilting up and down, the first thrust block 3 can prevent the extension plate 2 extending outwards from falling off from the deck platform 600, and safety is greatly improved.

Specifically, referring to fig. 5, the stop collar 1 of the present embodiment includes two first angle bars 11 disposed oppositely and at intervals, so that interference does not occur when other structures are disposed on the surface of the extension plate 2 later. As shown in fig. 5, the first angle steel 11 is L-shaped, and the bottom end of the first angle steel 11 is fixedly connected to the deck platform 600, for example, by welding. Referring to fig. 6 together, in order to prevent the first angle steel 11 from bending and deforming after being stressed, a triangular reinforcing block 12 is additionally arranged on the outer side surface of the first angle steel 11.

With reference to fig. 5, the extension plate 2 of the present embodiment is formed by welding two second angle steels 21 opposite and spaced to each other, and two spline plates 22 fixedly connected to the upper and lower ends of the second angle steels 21, so as to form a hollow structure, which can reduce the weight of the extension plate 2. In other embodiments, the second angle steel 21 and the figured steel plate 22 can be replaced by other metal pieces with lighter weight, such as aluminum alloy.

Further, referring to fig. 3 and 7 together, the end of the extension plate 2 near the leg 100 is provided with a second thrust block 4, so that the extension plate 2 cannot be completely removed from the stop collar 1. Preferably, two first thrust blocks 3 are symmetrically arranged at one end of the extension plate 2 of the present embodiment, and two second thrust blocks 4 are symmetrically arranged at the other end.

Still further, with reference to fig. 7 to 9, the movable platform is also provided with a locking assembly 5, the locking assembly 5 comprising a pin 51. Wherein, a first positioning hole is arranged on the upper end surface of the first angle steel 11. The extending plate 2 is provided with a second positioning hole at a position corresponding to the first positioning hole. The pin 51 is detachably inserted into the first positioning hole and the second positioning hole, so that the relative position of the extension plate 2 and the first angle steel 11 is basically fixed, and the operation is very convenient. With continued reference to fig. 9, to prevent the pin 51 from being lost, the locking assembly 5 further includes a ring-shaped round bar 52 fixedly attached to the first angle iron 11, and a chain 53 having one end connected to the round bar 52 and the other end connected to the pin 51.

Preferably, as shown in fig. 6 and 7, two railings 6 are further disposed on the extension board 2 along the long side direction, so that the safety of the movable platform can be improved again.

In particular, as shown in fig. 3 and 5, the mobile platform of the present embodiment further includes a pad 7 disposed on the deck platform 600 and under the extension board 2, so as to prevent the extension board 2 from rubbing the deck platform 600. Preferably, the base plate 7 of the present embodiment is two strip-shaped plates spaced apart from each other, so that the load of the deck platform 600 can be reduced. In other embodiments, the bottom surface of the extension plate 2 can also be provided with a roller or ball structure to reduce the friction between the bottom of the extension plate 2 and the backing plate 7.

In combination with the above detailed structural description of the movable platform, the following detailed description of the method for using the platform is provided with reference to fig. 10 and 11:

as shown in fig. 10, when the movable platform is needed, the extension plate 2 is pushed out toward the leg 100, and when the first thrust block 3 pushes against the end face of the first angle steel 11, the extension plate 2 stops. The crew steps from the extension panel 2 to the spud leg 100 and walks to the manhole cover 300.

When the movable platform is not required, the entire extension board 2 is pulled back onto the deck platform 600, and the pins 51 are inserted into the first and second positioning holes from top to bottom to lock the extension board 2, as shown in fig. 11.

While the present invention has been described with reference to the exemplary embodiments described above, it is understood that the terms used are words of description and illustration, rather than words of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
