[0029] Embodiment:

[0030] The preferred embodiment of the present application provides a steel rope winding device with adjustable pre-tightening force, which comprises two parallelly arranged rope winding drums 1, a rope pressing device 2 is arranged on both sides of the two rope winding drums 1, a steel rope 3 passes through the left rope pressing device 2 and is wound around the two parallelly arranged rope winding drums 1 as a whole, and then passes out from the right rope pressing device 2. Of course, the steel rope 3 passes out from the rope pressing devices 2 at both ends in order to realize fixation or use on both sides, especially for the case with counterweight, so that only one rope pressing device 2 can be used when needed. The use mode is obvious and will not be described.

[0031] The rope winding drum 1 and the rope pressing device 2 are arranged on the same bottom plate 4 or installed on the same horizontal plane, that is, the installation is kept on the same plane as much as possible, so that the steel rope 3 can pass through conveniently. Of course, the horizontal means that the height of the bottom surface is kept consistent to a certain extent, which is based on the height preset for the rope winding drum 1 and the rope pressing device 2, and the essential requirement is to realize cooperation in height, because the specifications can be adjusted according to the requirements, and the height difference can be provided if necessary.
