As shown in fig. 1, in one embodiment, the transition section includes a frame 100, a transition platform 200, and a ladder 300.

As shown in FIG. 1, in one embodiment, the frame 100 includes main chords 110, the main chords 110 being arranged in a first direction and in a rectangular arrangement.

It is understood that the adjacent two main chords 110 may be reinforced by providing web members to ensure structural strength and stability.

As shown in fig. 1, the web members may include a plurality of horizontal web members 120 arranged in a horizontal direction, and a plurality of inclined web members 130 arranged in an inclined direction, for example. The frame 100 further includes a middle web member 140, and each end of the middle web member 140 is connected to the two opposite main chords 110.

It should be understood that the definitions of horizontal, vertical, parallel, central, etc. for the orientation and position in the embodiments of the present application refer to the approximate horizontal, vertical, etc. direction and the approximate central position, etc. under the condition of neglecting various error conditions such as assembly error, measurement error, etc., and are not further described and defined herein.

With further reference to fig. 2, it should be understood that portions of the horizontal web member 120 and the diagonal web member 130 are omitted from fig. 2 for ease of viewing. In one exemplary embodiment, the transition section includes a total of four main chords 110, a first chord 111, a second chord 112, a third chord 113, and a fourth chord, with the four main chords 110 being arranged in a rectangular array along the first direction. After the transition joint is assembled on the tower crane, the directions of the four main chords 110 are in the vertical direction.

As shown in fig. 1, the frame 110 further includes an intermediate web member 140, and referring to fig. 2, in one embodiment, the intermediate web member 140 specifically includes a first web member 141 and a second web member 142, and the first web member 141 and the second web member 142 are disposed in parallel and in a horizontal direction.

The two ends of the first web member 141 and the second web member 142 are respectively connected to the two opposite main chords 110, and it can be understood that the first web member 141 and the second web member 142 are arranged along the diagonal direction of the four main chords 110 arranged in a rectangular shape.

As shown in fig. 2, in the present embodiment, the first web member 141 and the second web member 142 are connected to the second chord 112 and the fourth main chord 114.

As shown in fig. 1 and 2, the transition section further includes a transition platform 200, the transition platform 200 is disposed in a substantially horizontal direction, and the transition platform 200 is used for resting and stopping the worker during the climbing process. In one embodiment, the transition platform 200 may be a metal mesh structure, which can prevent rainwater from remaining and ensure a certain field of view while ensuring strength.

As shown in fig. 1 to 3, a first passage opening 210 is formed at the transition platform 200, and the first passage opening 210 is used for accommodating a ladder 300, so that the operator can climb from the lower part of the transition platform 200 to the upper part of the transition platform 200 through the first passage opening 210.

It can be understood that the directions of up, down, horizontal, vertical, etc. in this embodiment refer to directions in a normal installation or working state relative to the tower crane.

The ladder stand 300 in this embodiment specifically includes a first ladder stand 310 and a second ladder stand 320, wherein, the first ladder stand 310 is used for the operation personnel to climb to the transition platform 200 from the tower crane bottom, and the second ladder stand 320 is used for the operation personnel to continue climbing upwards from the transition platform 200. Obviously, when the climbing tower crane is implemented, the climbing directions of the operators can be opposite, that is, the operators can descend from the top of the tower crane to the transition platform 200 through the second ladder stand 320, and can also descend from the transition platform 200 to the bottom of the tower crane through the first ladder stand 310.

The top end of the first ladder 310 and the bottom end of the second ladder 320 are overlapped and spaced, and it can be understood that the first ladder 310 and the second ladder 320 are arranged in the same direction, but are staggered in position, so that a user can move to the transition platform 200 after climbing to the top of the first ladder 310, then further move to the second ladder 320 by the transition platform 200, and continue to climb along the second ladder 320.

As shown in fig. 3, in one embodiment, the orthographic projection of the first ladder 310 in the plane of the transition platform 200 does not overlap with the transition platform 200, and it can be understood that the first ladder 310 is located in the area of the first passage opening 210 for the worker to climb from the first passage opening 210 to the transition platform 200.

In the related art, the ladder stand 300 is continuously provided, and it can be understood that the ladder stand 300 is continuously provided from the bottom to the top of the tower crane, so that the worker can continuously climb on the ladder stand 300, and the platform for the worker to rest is generally provided in the lateral direction of the ladder stand 300, so that the worker needs to actively move to the platform in the lateral direction of the ladder stand 300 if the worker needs to temporarily rest. Therefore, in the related art, if the operator accidentally drops off his/her hands while climbing, the operator may slip off a long distance and even fall off the tower crane.

Obviously, there is also a ramp scheme in the related art, that is, the ladder 300 is inclined with respect to the vertical direction, so that the transition platform 200 can be arranged at the bottom of the ramp, and the ramp scheme has high safety, but the ramp occupies a relatively large space and is expensive to manufacture, which makes it difficult to apply and implement the ramp in various situations.

The technical solution of this embodiment is a vertical ladder solution, that is, the first ladder 310 and the second ladder 320 are both disposed along the first direction, that is, the extending direction of the main chord 110, in other words, the first ladder 310 and the second ladder 320 are disposed in the vertical direction.

As shown in fig. 1 and fig. 2, in the technical solution of this embodiment, in some embodiments, the planes of the first ladder stand 310 and the second ladder stand 320 are parallel to each other, and it can also be understood that the first ladder stand 310 and the second ladder stand 320 are arranged parallel to each other.

In some embodiments, the transition section further comprises a connecting rod 330, and the top end of the first ladder stand 310 is fixed to the bottom end of the second ladder stand 320 through the connecting rod 330, so that the first ladder stand 310 and the second ladder stand 320 are spaced apart in a direction perpendicular to the first direction.

The two ends of the connecting rod 330 may be fixed to the first ladder stand 310 and the second ladder stand 320, respectively, and may be fixed by welding, fastening, and the like, for example. This allows the first ladder 310 and the second ladder 320 to form a unitary structure and further connect to the frame 100 of the transition section.

In some embodiments, the ladder 300 is connected to the frame 100 at an intermediate web member, in this embodiment, the first ladder 310 is connected at its bottom end to the first web member 141 and the second ladder 320 is connected at its top end to the second web member 142.

In some of these embodiments, to provide more climbing space for the user, the first ladder 310 is connected to a central or substantially central location of the first web member 141 and the second ladder 320 is connected to a central or substantially central location of the second web member 142.

In one embodiment, the first ladder 310 and the second ladder 320 overlap somewhat in their length direction, as shown in figures 1 and 3, it will be appreciated that the height of the top of the first ladder 310 is higher than the height of the bottom of the second ladder 320. The first ladder 310 and the second ladder 320 are connected by a support bar, which in one embodiment is arranged in a direction crossing the length direction of the first ladder 310 and the second ladder 320, and may be, for example, perpendicular to the first ladder 310 and the second ladder 320, such that the first ladder 310 and the second ladder 320 remain substantially parallel after being fastened by the support bar.

As shown in fig. 1 and fig. 3, during climbing, a worker first climbs to the transition platform 200 through the first ladder 310, at this time, the worker cannot climb up through the first ladder 310, and the worker needs to first transfer to the transition platform 200, walk around the transition platform 200 to the second ladder 320, and climb up through the second ladder 320.

In contrast to the above process, when the worker descends, he first needs to descend to the transition platform 200 via the second ladder 320, then to go around to the first ladder 310, and continue to descend via the first ladder 310.

In the technical solution of this embodiment, the climbing surface of the second ladder 320 is located on a side of the second ladder 320 far away from the first passing opening 210. As shown in fig. 3, in some embodiments, the orthographic projection of the second ladder 320 in the plane of the transition platform 200 is within the range of the transition platform 200, that is, the bottom of the second ladder 320 is the transition platform 200, so that when the worker slips or falls off the second ladder 320, the transition platform 200 can play a role in bearing and protecting, which helps to reduce the work risk.

In order to ensure that the worker climbs or descends upward on the side of the second ladder 320, the position of the second passage opening in the cover plate above the second ladder 320 can further be adjusted in this embodiment. It will be appreciated that the transition section may be provided on a standard section and a slewing structure, where the slewing structure may be a boom of a tower crane, and that a top platform for access by the operator may be provided on the slewing structure, and the second ladder 320 is accessible to the top platform through a second access opening, and by adjusting the position of the second access opening such that the second access opening is located on the side of the second ladder 320 remote from the first ladder 310, it is ensured that the operator will get on and off the second ladder 320 on the side of the second ladder 320 remote from the first ladder 310.

In some of these embodiments, the first ladder 310 and the second ladder 320 are connected to the middle web member from opposite directions. That is, the first ladder 310 and the second ladder 320 are respectively disposed on opposite sides of the middle web member.

As shown in fig. 1 and 3, the first ladder 310 is connected to the first web member 141 by a first connecting portion 311, and the second ladder 320 is connected to the second web member 142 by a second connecting portion 321, wherein the first connecting portion 311 is located on a side of the first web member 141 facing away from the second connecting portion 321.

With continued reference to fig. 1 and 2, the middle web member divides the rectangular space defined by the main chord 110 into two triangular spaces, the first ladder stand 310 is connected to the first web member 141 in one of the triangular spaces, and the second ladder stand 320 is connected to the second web member 142 in the other triangular space.

It can also be understood that the first connection portion 311 of the first ladder 310 and the first web member 141 is located on the side of each intermediate web member facing the first chord 111, and the second connection portion 321 of the second ladder 320 and the second web member 142 is located on the side of each intermediate web member facing the third chord 113.

In some embodiments, the first ladder 310 and the second ladder 320 are the same length along the direction of extension of the first ladder 310 and the second ladder 320. It will be appreciated that the first ladder 310 and the second ladder 320 in this embodiment are of the same construction so that only one part of the ladder 300 of the same shape needs to be produced and then the two ladder 300 parts are connected to each other, one as the first ladder 310 and the other as the second ladder 320, which helps to simplify the production process and reduce production costs. The embodiment of the application also provides the tower crane. The tower crane comprises all technical schemes of the transition section embodiment, so that all technical effects can be at least realized, and the details are not repeated here.

While the foregoing is directed to the preferred embodiment of the present application, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the principles of the disclosure, and it is intended that such changes and modifications be considered as within the scope of the disclosure.
