Detailed Description

The following are specific examples of the present invention, and the technical solutions of the present invention are further described with reference to the drawings, but the present invention is not limited to these examples, and the following embodiments do not limit the invention according to the claims. Moreover, all combinations of features described in the embodiments are not necessarily essential to the solution of the invention.

It will be understood by those of ordinary skill in the art that all directional references (e.g., above, below, upward, downward, top, bottom, left, right, vertical, horizontal, etc.) are illustratively used in the figures to aid the reader's understanding and do not imply (e.g., position, orientation, or use, etc.) a limitation on the scope of the invention, which is defined by the claims appended hereto. Additionally, the term "substantially" may refer to slight imprecision or deviation in conditions, amounts, values, or dimensions, etc., some of which may be within manufacturing or tolerance limits.

Example one

As shown in fig. 1, 2 and 3, a communication tower lifting device comprises a tower body, an antenna 201 arranged on the tower body, the antenna is connected with the tower body through an antenna support, the tower body is a pipe body 1, the bottom of the pipe body is provided with a lower inlet 101, the upper part of the pipe body is provided with an upper access 102, the antenna bracket comprises an annular maintenance platform 2 which is movably sleeved on the pipe body, a manned lifting platform 3 is arranged in the pipe body, the manned lifting platform is connected with an annular maintenance platform through a traction rope 4, the weight of the annular maintenance platform is larger than that of the manned lifting platform, but not so much different, preferably not exceeding the average adult weight, the bottom outside the upper access opening is provided with a stop 5 preventing the annular maintenance platform from descending, when the annular maintenance platform supports the blocking body, the manned lifting platform corresponds to the inlet and the outlet, and the annular maintenance platform further comprises a lifting control device for controlling the manned lifting platform to move up and down relative to the pipe body. Of course, the guide wheels 301 can be supported between the manned lifting platform and the annular maintenance platform and the pipe body, the inner wall of the pipe body can be provided with guide grooves in the vertical direction, and the guide wheels 301 are matched in the guide grooves, so that the more smooth vertical movement of the manned lifting platform and the annular maintenance platform is reduced; the lower access and the upper access are both provided with doors; and a guide pulley 6 is supported between the traction rope and the pipe body. Lifting control device is from the top down the climbing handle 7 that the body inner wall distributes to it is supplementary through climbing handle that the workman carries the rising or the decline of manned elevating platform, of course, leading wheel 301 should stagger with the climbing handle position, avoids climbing the handle and blocks leading wheel up-and-down motion.

Further, set up the counter weight on the elevating platform, the counter weight is counter weight disc 8, and is a plurality of the counter weight disc stacks in the pipe body of manned elevating platform below, the shoulder hole has on the counter weight disc, the aperture 801 of shoulder hole is last, the macropore 802 of shoulder hole is under, the aperture of shoulder hole has two radial notches 803 of symmetry, manned elevating platform bottom has counter weight connecting rod 9, the gliding passing of direction from top to bottom of counter weight connecting rod manned elevating platform bottom, the sheer pole 10 is connected to counter weight connecting rod lower extreme, sheer pole length is less than the distance of two radial notches. The upper end of the counterweight connecting rod is connected with an upper cross rod 11, and a spring 12 is supported between the upper cross rod and the bottom of the manned lifting platform, so that the upper cross rod has an upward trend.

The lowermost counterweight disc is fixedly connected with the pipe body. And a pressure sensor 13 for supporting the bottom of the manned lifting platform is arranged at the bottom of the inner side of the lower access opening.

When the lifting control device is not used, the manned lifting platform can be fixed at a lower entrance through a temporary connecting device, such as a device which is convenient to fix and separate, such as a hook or a lock, and the like, a lower cross rod at the lower end part of the counterweight connecting rod is positioned in a large hole of a counterweight at the lowest part and clamped at a step, so that the manned lifting platform cannot lift up, when an antenna needs to be maintained, a door is opened to enter the manned lifting platform in a pipe body, an upper cross rod of the counterweight connecting rod is rotated, so that the lower cross rod of the counterweight connecting rod corresponds to a radial notch of the counterweight disc, the counterweight connecting rod moves upwards, the number of required counterweight discs is determined according to the size of a pressure sensor (the force detected by the pressure sensor is the weight difference value between the annular maintenance platform and the manned lifting platform, and the increased number of the counterweight discs makes the counterweight discs as small as possible), for example, the lower cross bar is moved into the large hole of the first step hole of the counterweight, and then the counterweight connecting rod is rotated, so that the lower cross bar is clamped at the step, and the counterweight discs can be lifted together when the manned lifting platform is lifted. When it is desired to ascend, the temporary connection means is opened, and then the worker may ascend or descend by slightly climbing the handle. For example, if the weight of the annular maintenance platform is greater than the people lift, the worker is prevented from rising too fast by the aid of the climbing handle, and vice versa.

When the annular maintenance platform descends to the blocking body, the manned lifting platform also moves to the upper access, at the moment, a worker enters the annular maintenance platform through the upper access, returns to the manned lifting platform after the maintenance work is finished, can descend in an opposite mode, and then fixes the lower cross rod into the large hole of the lowest counter weight.

Example two

As shown in the figure, different from the above embodiment, the lifting control device is a rope winding and unwinding device, the rope winding and unwinding device is pulled by a rope, the rope winding and unwinding device can be a hand winch 14, the rope is connected to the bottom of the manned lifting platform, and an assistant person outside the pipe controls the winding and unwinding of the rope by the hand winch.
