[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1, reference Figure 1 - Figure 4, which is the first embodiment of the present invention, provides a follow-up cement pole safety belt hanging point device, including an installation unit 100, including a rotating bracket 101, a rotating bracket 102, a movable bracket 103 and a movable bracket 104, and an adjustment component 107 arranged between the rotating bracket 101 and the movable bracket 103.

[0028] Among them, the rotating bracket 101 and the rotating bracket 2 102 are arranged in a mirror image and are rotatably connected at adjacent locations by a hinge 105, so that the rotating bracket 101 and the rotating bracket 2 102 are fixedly connected together at adjacent locations and can rotate, and the movable bracket 103 and the rotating bracket 2 102 are arranged in a mirror image and are movably connected at adjacent locations by a lock 106, so that the movable bracket 103 and the movable bracket 2 104 can be temporarily fixedly connected together by the lock 106, and the opening and closing of the movable bracket 103 and the movable bracket 2 104 can be achieved by turning the lock 106.

[0029] Furthermore, the adjustment component 107 includes a stepper motor 107a, a linear guide rail 107b, a fixed block 107c and a limit block 107d. The stepper motor 107a is arranged between the rotating bracket 101 and the movable bracket 103, the driving end of the stepper motor 107a is located outside the movable bracket 103, and the output end of the stepper motor 107a is threadedly connected with the fixed block 107c. When the stepper motor 107a is driven to rotate, the fixed block 107c can be driven to slowly approach the driving end of the stepper motor 107a while rotating. Since the fixed block 107c is rotatably connected to the rotating bracket 101 through a bearing, the fixed block 107c drives the rotating bracket 101 to approach the movable bracket 103.

[0030] The linear guide 107b is arranged between the rotating bracket 101 and the movable bracket 103, and is located above and below the stepping motor 107a. The fixed end of the linear guide 107b is fixedly connected to the movable bracket 103, and the other end of the linear guide 107b passes through the rotating bracket 101 and is movably connected to the limiting block 107d. When the fixed block 107c drives the rotating bracket 101 to move, the linear guide 107b can provide a guiding effect to ensure that the rotating bracket 101 and the movable bracket 103 are parallel to each other, that is, the rotating bracket 101 moves closer to or away from the movable bracket 103.

[0031] When the fixed block 107c is driven by the stepper motor 107a, it starts to move through the threaded connection. The linear guide 107b provides a guiding function in this process to ensure that the fixed block 107c moves along a predetermined linear path. The movement of the fixed block 107c drives the rotating bracket 101 to move along the linear guide 107b through the bearing to maintain the relative position and direction of the rotating bracket 101 and the movable bracket 103. The design and layout of the linear guide 107b ensure that the rotating bracket 101 maintains the relative position and direction with the movable bracket 103 when moving. The precise control capability of the stepper motor 107a enables the movement of the rotating bracket 101 to be precisely adjusted to achieve fine-tuning or precise positioning, whether it is approaching or moving away from the movable bracket 103. The limit block 107d acts as a limit at the other end of the linear guide rail 107b to prevent the rotating bracket 101 from moving excessively, thereby ensuring the stability and safety of the structure. The precise relative movement between the rotating bracket 101 and the movable bracket 103 can be achieved, and the parallel relationship between the two can be maintained, whether it is approaching or moving away.

[0032] Among them, the adjustment component 107 is also arranged between the rotating bracket 102 and the movable bracket 104, so that the rotating bracket 101, the rotating bracket 102, the movable bracket 103 and the movable bracket 104 are connected together to form a circular ring structure, and the movable bracket 103 and the movable bracket 104 are opened and closed at adjacent positions through the adjustment of the lock 106, so as to achieve the effect of setting the device on the outside of the pole, and by driving the stepper motor 107a on the movable bracket 103 and the movable bracket 104, the rotating bracket 101, the rotating bracket 102, the movable bracket 103 and the movable bracket 104 simultaneously apply extrusion force to the surface of the pole, so that the device is fixed on the outside of the pole.

[0033] Also, the ultrasonic probe 108 and the crawler 109 on the inner sides of the rotating bracket 101, the rotating bracket 2 102, the movable bracket 1 103 and the movable bracket 2 104, the crawler 109 can drive the device to move vertically along the outer wall of the pole.

[0034] Example 2, reference Figure 1 - Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the detection unit 200 includes a detection component 201 arranged on the movable bracket 2 104 and a driving unit 202 arranged on the rotating bracket 101.

[0035] Furthermore, the ultrasonic controller 201a is arranged on the outside of the movable bracket 104 near the upper part, and is responsible for controlling the operation of the ultrasonic probe 108, including transmitting and receiving ultrasonic signals. It is located below the ultrasonic controller 201a and provides power for the ultrasonic controller 201a and other electronic components. The main control board 201c is located below the battery pack 201b. As the main control unit of the system, it is responsible for processing data from the ultrasonic controller 201a and other sensor signals and executing corresponding control logic. The laser sensor 201d is arranged inside the movable bracket 104 for detecting specific targets or measuring distances and providing high-precision measurement data. The ultrasonic probe 108 is used in conjunction with the ultrasonic controller 201a to measure distances or detect obstacles.

[0036] Furthermore, a human body sensor 202a is arranged at the bottom of the rotating bracket 101 to detect the distance between the device and the staff. The driving plate 202b is arranged on the outside of the rotating bracket 101 to control the operation of the stepper motor 107a and receive the instructions of the main control board 201c to achieve precise motion control. The stepper motor 107a cooperates with the driving plate 202b to perform precise stepping motion according to the instructions of the driving plate 202b to achieve the clamping force of the device on the pole.

[0037] When the device is started, the distance between the device and the worker is preset in the main control board 201c. When the worker is climbing, the device is always on top of the worker. The human sensor 202a detects the distance between the device and the person and controls the device to maintain the set distance with the worker until the worker climbs to the predetermined position, or the device automatically stops rising after encountering an obstacle or reaching the top of the pole. Since the device uses the crawler 109 as a drive, it can well cross the depression at the joint of the pole.

[0038] During the climbing process of the device, the ultrasonic probe 108 detects the distance between the device and the pole, and receives the ultrasonic probe 108 through the ultrasonic controller 201a, transmits it to the main control board 201c to control the rotation of the stepper motor 107a, tighten the rotating bracket 101, the rotating bracket 2 102, the movable bracket 1 103 and the movable bracket 2 104, so that the track 109 maintains a certain contact pressure with the pole, and the device can reliably move up and down on the pole.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3, reference Figure 1 - Figure 4 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the protection unit 300 includes a safety rod 301 and a reset component 302 arranged on the safety rod 301 and connected to the installation unit 100.

[0041] Furthermore, the safety rod 301 is in the shape of a Chinese character "U", which is convenient for the safety hook on the staff's safety belt to be installed on the safety rod 301. The connecting rod 302a is divided into two groups, each group of two, which are rotatably connected to the outer walls of the two sides of the safety rod 301 through a rotating shaft. The other end of the connecting rod 302a is rotatably connected to the rotating bracket 101, the rotating bracket 2 102, the movable bracket 1 103 and the movable bracket 2 104 through the rotating shaft, allowing the safety rod 301 to rotate relative to these. The tension spring 302b is arranged on both sides of the safety rod 301, and the other end of each group of tension springs 302b is fixedly connected to the movable bracket 103 and the movable bracket 2 104, respectively, to provide restoring force for the safety rod 301. When the safety rod 301 deviates from its original position due to external force, the elastic action of the tension spring 302b will prompt the safety rod 301 to return to its initial position, that is, reset. The rotating connection design of the connecting rod 302a enables the safety rod 301 to flexibly adapt to different directions and angle changes during the resetting process.

[0042] The remaining structure is the same as that of Example 2.
