The following examples are further illustrative and supplementary to the present invention and do not limit the present invention in any way.

As shown in fig. 1 to 5, the screw lifting device of the present invention includes a screw 10, a driving device 20, and a lifting fixing base 30. The screw 10 is used for being vertically arranged on the climbing frame 40, and can rotate under the driving of the driving device 20. The lifting fixing base 30 is connected to the screw rod 10 in a threaded manner, and when the screw rod 10 rotates, the lifting fixing base 30 moves relative to the screw rod 10. When the climbing frame is lifted, the lifting fixing seat 30 is fixedly connected with a wall-attached support 60 fixed on a building wall 50, and the driving device 20 can drive the screw 10 to rotate to drive the climbing frame 40 to lift the wall-attached frame.

As shown in fig. 1 to 5, the screw 10 is movably connected to the climbing frame 40 through a bearing 70. Specifically, two ends of the screw 10 are respectively connected with the climbing frame 40 through bearings 70, an end of the screw 10 is connected with an inner ring of the bearing 70, and an outer ring of the bearing 70 is fixedly connected with the climbing frame 40, so that the screw 10 can rotate on the climbing frame 40. In this embodiment, the bearing 70 is a deep groove ball bearing, and the screw 10 is a trapezoidal screw.

As shown in fig. 1 to 5, the length of the screw 10 can be set according to the requirement, and in this embodiment, the length of the screw 10 is slightly greater than the story height of the building.

As shown in fig. 1 to 5, the driving device 20 is provided on the creeper 40, and drives the screw 10 to rotate. The driving device 20 is disposed at an end position of the screw 10, in this embodiment, the driving device 20 is disposed at a lower end of the screw 10. In other embodiments, the driving device 20 may also be disposed at the upper end of the screw 10.

As shown in fig. 1 to 5, the driving device 20 includes a driving motor 21, a reduction gear mechanism 22, and a driving gear 23.

As shown in fig. 1 to 5, the driving motor 21 is fixed on the climbing frame 40, and may be a suitable motor type according to actual conditions. In this embodiment, the driving motor 21 is disposed horizontally, and an output shaft thereof is disposed horizontally.

As shown in fig. 1 to 5, the reduction transmission mechanism 22 is provided on the climbing frame 40, connected to an output end of the driving motor 21, and configured to transmit the driving gear 23. In this embodiment, the reduction transmission mechanism 22 is a worm and gear reduction mechanism, which includes a worm and a gear. The worm is arranged in the horizontal direction and is coaxially and fixedly connected with an output shaft of the driving motor 21. The worm wheel is meshed with the worm, and the axial direction of the worm wheel is parallel to the axial direction of the screw 10. The worm gear and worm speed reducing mechanism has a self-locking function, can play a role in preventing falling, and avoids falling of the climbing frame in the use process.

As shown in fig. 1 to 5, the driving gear 23 is coaxially fixed to the screw 10 and can rotate synchronously with the screw 10. The driving gear 23 is connected to the reduction transmission mechanism 22, and in this embodiment, the driving gear 23 is engaged with the worm gear.

When the driving motor 21 works, the power is output to the worm of the speed reduction transmission mechanism 22, the worm works to drive the worm wheel to rotate, the worm wheel rotates to drive the driving gear 23 to rotate, and the driving gear 23 rotates to drive the screw rod 10 to rotate.

As shown in fig. 1 to 5, the lifting fixing base 30 is screwed to the screw rod 10 and can be connected to a wall-attached support 60 fixed to a building wall 50. The lifting fixing seat 30 is provided with a screw hole, which can be fixedly connected with the wall-attached support 60 through a bolt 80 and can be conveniently detached from the wall-attached support 60. A nut is fixedly arranged on the lifting fixing seat 30. The internal thread of the nut matches the thread of the screw 10. The nut is sleeved on the screw rod 10 and is in threaded connection with the screw rod 10.

Thus, the screw lifting device of the utility model is formed: the screw 10 can be vertically arranged on the climbing frame 40, and can rotate under the driving of the driving device 20, and the lifting fixing seat 30 is connected to the screw 10 in a threaded manner and can be fixedly connected with the wall-attached support 60.

The working principle and the using method of the screw lifting device are as follows:

as shown in fig. 1, the screw elevating device is installed on a climbing frame 40, and the climbing frame 40 is attached to the building wall through other known structures. On the building wall 50, for example, a known wall-attached support 60 is installed at the nth floor, the lifting fixing base 30 is moved to the upper end of the screw rod 10, and then the lifting fixing base 30 and the wall-attached support 60 at the nth floor are fixedly connected together. When the driving device 20 is started, the driving motor 21 drives the driving gear 23 to rotate forward through the speed reduction transmission mechanism 22, so as to drive the screw rod 10 to rotate forward. Since the lifting fixing base 30 is fixed on the building wall 50 through the wall-attached support 60, the screw 10 is moved upward relative to the lifting fixing base 30 by the forward rotation of the screw 10, so that the entire climbing frame 40 is lifted upward relative to the building wall 50, and the climbing frame 40 is lifted, for example, lifted one floor upward.

In the lifting process, the position of the lifting fixing seat 30 relative to the screw rod 10 changes; as shown in fig. 1, before lifting, the lifting fixing base 30 is located at the upper end of the screw bar 10. As shown in fig. 2, after lifting, the lifting fixing base 30 is located at the lower end of the screw bar 10.

As shown in fig. 2, after the climbing frame 40 is lifted to a predetermined height, for example, after a floor is lifted, the climbing frame 40 is fixed to the building wall 50 by a known method; then, separating the lifting fixing seat 30 from the wall-attached support 60 on the nth layer; then the driving motor 21 is controlled to rotate reversely, the driving gear 23 is driven to rotate reversely, and the screw rod 10 is driven to rotate reversely; since the creeper 40 is fixed and the lifting fixing base 30 is separated from the wall-attached support 60, the reverse rotation of the screw 10 drives the lifting fixing base 30 to move upward relative to the screw 10, so that the lifting fixing base 30 moves from the lower end of the screw 10 to the upper end of the screw 10 (as shown in fig. 3), i.e. from the nth layer to the (N + 1) th layer.

As shown in fig. 3, after the lifting fixing seat 30 moves to the upper end of the screw 10, for example, after the N +1 th floor, when the climbing frame 40 needs to be lifted again, the lifting fixing seat 30 is fixedly connected to the wall-attached support 60 on the N +1 th floor, and then the climbing frame 40 can be lifted by driving the motor 21 to rotate forward.

While the utility model has been described with reference to the above embodiments, the scope of the utility model is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the spirit of the utility model.
