The platform mechanism is arranged in the tower barrel and used for an operator to climb the upper platform, and a peripheral tower barrel is omitted in the drawing. Said ladder 2 cooperates with the opening 11, in particular the ladder 2 may be arranged below the opening 11, or the ladder 2 may extend through the opening 11.

The platform structure of this embodiment sets up open closed door 4 through opening 11 below at upper platform 1 to door 4 is in horizontal position when closing, and operating personnel can stand and accomplish the operation of removing or tying safety lock on second platform 3's door 4 like this, and like this, even operating personnel has removed safety lock, also can not take place to fall on being in second platform 3, can effectively avoid the risk of falling, reduce the emergence of accidental injury, improve the factor of safety of operation.

The door 4 is provided in front of the ladder 2, and the front of the ladder 2 is a side where the operator climbs the ladder 2. Even if the operator accidentally falls from the ladder stand 2 without fastening the safety lock catch, the operator can fall onto the second platform 3 without continuously falling down under the condition that the door 4 is closed, and the accidental injury can be effectively reduced.

In particular, the second platform 3 further comprises a support 31. The bracket 31 is used to mount and support the door 4. The bracket 31 supports the door 4, particularly when the door 4 is in a horizontal position. The door 4 is thus supported by the support 31 and can carry a certain weight for the operator to stand and work on the second platform 3.

Alternatively, the bracket 31 is fixed to the upper platform 1 so that the weight of the second platform 3 and the operator can be carried by the upper platform 1, enhancing the load-bearing and strength of the second platform 3. In another way, the support 31 is fixed to the inner wall of the tower, which carries the weight of the second platform 3 and the operator.

The guard rail 32 thus serves both as a guard and as a connecting and fixing support 31, making the second platform 3 more compact, having a smaller number of parts and light in weight. Optionally, a connecting plate 33 is provided at the upper end of the guardrail 32, and the guardrail 32 can be connected with the upper platform 1 through the connecting plate 33.

Alternatively, the door 4 may be engaged with the bracket 31 in a variety of ways, as described in more detail below with respect to the particular manner in which the door 4 engages the bracket 31.

Fig. 1 to 7 show a manner of engagement of the door 4 and the bracket 31, in which the door 4 is hinged to the bracket 31 and the door 4 can be turned upwards. Specifically, the door 4 is a reversible flap plate 41, and one end of the flap plate 41 is hinged to the bracket 31 by a hinge 43 so that the flap plate 41 can be rotated about the hinge axis. Specifically, when the roll-over panel 41 is rotated to the horizontal position, the door 4 is in the closed position, and the roll-over panel 41 is supported by the bracket 31 at this time, and can bear a certain weight for the operator to stand and operate. When the door 4 needs to be opened, the turnover plate 41 is turned upwards. The door 4 preferably adopts a structure that the door is turned upwards to a vertical position to be opened and turned downwards to a horizontal position to be closed, so that the door 4 can be supported and limited by the bracket 31 at the horizontal position and cannot continue to rotate downwards, and the phenomenon that the door 4 is accidentally turned downwards to cause the falling of an operator and the injury can be avoided.

Alternatively, in this fitting mode, the bracket 31 comprises two opposite support portions, one of which is hinged to the flap plate 41 and supported in a horizontal position by the other support portion. The support part includes a horizontal support plate 311, and the support plate 311 can be used to support the flipping plate 41 and to connect the guard rail 32.

Optionally, the supporting plate 311 is further provided with a reinforcing rib 312, the reinforcing rib 312 can enhance the strength of the supporting plate 311, and the reinforcing rib 312 can be used for supporting the flipping plate 41. It should be noted that the structure of the bracket 31 is not limited to the structure of two supporting portions, and any structure suitable for mounting and carrying the door 4 is within the limit of the present embodiment.

A second way of cooperating the door 4 and the bracket 31 is shown in fig. 8 and 9, in which the door 4 is a folding door comprising at least two hinged folding plates 44, one end of the door 4 is hinged to the bracket 31, and the door 4 can be unfolded or folded in a horizontal direction. The number of the folding plates 44 is not limited to two, and may be more than 3, and the folding plates are connected in sequence in an end-to-end hinged manner.

Optionally, one of the folding plates 44 at the extreme edge is hinged to the bracket 31 by a hinge 43. In the horizontally unfolded state, the door 4 is in the closed position, and the bracket 31 can provide support for all the folding plates 44, so that the door 4 can bear certain load. The structure of the folding door can save the space in the vertical direction, and compared with the mode of the turnover plate 41, the folding door is labor-saving to operate when being folded or unfolded (opened or closed).

A third way of cooperating the door 4 and the bracket 31 is shown in fig. 10 and 11, in which the door 4 is a sliding door 45, which is horizontally slidably arranged on the bracket 31. In comparison to the first two modes of engagement, the weight of the sliding door 45 is borne by the bracket 31, so that the force required to open and close the door 4 is minimal and the operation is easiest. However, the sliding door 45 occupies a large space in the transverse direction.

It should be noted that the manner of fitting the door 4 and the bracket 31 in this embodiment is not limited to the above three specific manners of fitting, and any manner of fitting the door and the bracket that satisfies the requirement that "the door is openable and closable, and the door is in a horizontal position when closed" is within the limit of this embodiment.

Optionally, as shown in fig. 6, a handle 42 is provided on the door 4. Optionally, a handle 42 may be provided on one or both sides of the door 4 to facilitate the operator opening and closing the door 4.

Optionally, the platform structure of the tower further comprises a drive mechanism connected to the door 4 for opening and closing the door 4. The driving mechanism may be a motor, a cylinder, etc., and may open and close the door 4 according to the control of an operator. Thus, an operator can hold the ladder 2 with two hands to wait for the driving mechanism to open the door 4 or close the door 4 without using one hand to open and close the door 4, and the risk of accidents is further reduced.

The following describes the operation of the operator in the platform structure of the present embodiment: when an operator needs to climb the upper platform 1, the climbing ladder 2 is firstly reached below the second platform 3, the door 4 is opened and continuously moves upwards between the second platform 3 and the upper platform 1, and then the operator closes the door 4 to enable the door 4 to be in a horizontal position. Then the operator can be separated from the ladder 2 and stand on the second platform 3 to safely release the safety lock catch, and the operator cannot be in danger of falling due to the protection of the second platform 3. When the operator needs to leave from the upper platform 1, the door 4 is in a closed state at the moment, the operator firstly climbs the second platform 3, the safety lock catch is tied on the second platform 3, then the operator climbs the ladder 2 to ascend for a short distance, opens the door 4 and then descends, and therefore the operator is always protected by the second platform 3 under the condition that the safety lock catch is not tied, and the danger of accidental falling is avoided.
