[0027] The present application provides a hoisting and supporting device of a wind turbine tower hoist. Figures 1-8As shown, the lifting support device comprises a pair of parallel support beams 1, a hoist beam 2 for mounting the elevator steel wire rope, and a mounting seat 3 fixedly connected with the inner wall 4 of the tower drum, both ends of the support beam 1 are bolted to the mounting seat 3, and a plurality of groups of first bolt connection holes 111 adapted to be connected with both ends of the hoist beam 2 are arranged on the support beam 1 along the length direction, so that the mounting position of the hoist beam 2 can be adjusted along the length direction of the support beam 1. By adjusting the position of the hoist beam 2 along the length direction of the support beam 1, the position of the elevator 5 can be arranged as required between the inner wall 4 of the tower drum and the twisted cable located in the middle of the tower drum, so that it can be adapted to various models and sizes of elevators.

[0028] According to the embodiment of the utility model, the main body of the support beam 1 is H-shaped steel 11, a plurality of groups of first bolt connection holes 111 are arranged on the upper flange plate of the H-shaped steel 11, each group comprises two first bolt connection holes 111 respectively located on both sides of the web plate; preferably, the interval of each adjacent two groups of first bolt connection holes 111 is equal, so that the minimum adjustment distance of the hoist beam 2 installation is equal to the interval of the adjacent two groups of first bolt connection holes 111, thereby realizing the fine adjustment of the installation position of the hoist beam 2. Two ends of the lower flange plate of the H-shaped steel 11 are respectively provided with second bolt connection holes 112 for connecting with the mounting seat 3 on both sides of the web plate. Preferably, the support beam 1 further comprises a rib plate 12, which is respectively welded with the upper and lower flange plates and the web plate of the H-shaped steel 11, so as to strengthen the supporting strength of the lifting support device, prevent the support beam from being too long to cause bending when installed in the high-power unit tower drum, and improve the safety and reliability of the device.

[0029] According to the embodiment of the utility model, the hoist beam 2 comprises a pair of channel steels 21 oppositely arranged in notches and a hoist plate 22 bolted between the pair of channel steels 21. The lifting holes on the hoist plate 22 can be designed according to the interfaces provided by different elevator manufacturers and as compatible as possible. For those that cannot be compatible, different hoist plates 22 can be designed, and the appropriate one can be selected and bolted with the channel steel 21. Two long bolt connection holes 211 for connecting with the support beam 1 are respectively arranged at both ends of the lower flange plate of each channel steel 21, so that both ends of the hoist beam 2 are bolted to the support beam 1 through four bolts; the interval of the corresponding long bolt connection holes 211 on the two channel steels 21 is equal to the interval of each adjacent two groups of first bolt connection holes 111 on the support beam 1, so that the minimum installation adjustment distance of the hoist beam 2 along the length direction of the support beam 1 is equal to the distance between the center lines of the long bolt connection holes 211 on the two channel steels 21. The length direction of the long bolt connection hole 211 is consistent with the length direction of the hoist beam 2, so as to ensure the adaptation with each group of first bolt connection holes 111 on the support beam 1, and avoid the failure of smooth bolt connection when the installation position of the hoist beam 2 needs to be adjusted due to machining error.

[0030] According to the embodiment of the utility model, the mounting seat 3 comprises a vertical steel plate 31 and a horizontal steel plate 32 which are connected with each other, and the outer sides of the vertical steel plate 31 and the horizontal steel plate 32 are respectively welded to the inner wall of the tower drum, so that the mounting seat 3 and the inner wall of the tower drum form spaced apart welding areas in the horizontal and vertical directions, thereby improving the connecting strength of the hoisting support device and the tower drum. The horizontal steel plate 32 is provided with bolt connecting holes 321 located on both sides of the vertical steel plate 31, and preferably, the two bolt connecting holes 321 on the same horizontal steel plate 32 are symmetrically arranged as long curved holes. Correspondingly, the second bolt connecting hole 112 of the support beam 1 is a long straight hole, and the long curved hole and the long straight hole are matched to adjust the position of bolt connection as required, thereby adjusting the relative position between the support beam 1 and the mounting seat 3 and between the pair of support beams 1, so as to improve the adaptability of the device to the tower drums of different sizes, and the number of connecting bolts can be adjusted according to the bearing requirement. In addition, in order to avoid interference with the twisted cable in the middle of the tower drum, the distance L between the pair of support beams 1 is greater than 600 mm.
