They are widely used in high-altitude work scenarios such as power construction, communication tower construction, wind turbine tower maintenance, and building construction. However, existing fall arrestor rail assemblies have some shortcomings, such as:

[0003] The fall protection device for a guide rail hydraulic lifting platform described in application number CN202510253399.2, while having a clear functional orientation and protective role in the field of guide rail hydraulic lifting platforms, has obvious limitations in its scope of application. This device is only designed for guide rail hydraulic lifting platforms, and it is difficult to play its fall protection function in other high-altitude operation scenarios such as tower climbing and building facade construction, failing to meet the safety protection requirements in these scenarios. At the same time, as can be seen from the patent information, it does not mention the modular design concept, which means that in actual use, once a component is damaged or needs to be upgraded, the replacement of the component is difficult, and the overall assembly lacks flexibility. It cannot be like modularly designed components, which can be quickly and conveniently replaced or combined according to different needs, thus affecting the maintenance efficiency and ease of use of the equipment to a certain extent.

The first adjustment block is rotatably connected to the top of the first support frame. The top of the first adjustment block has a circular structure, which facilitates the rotation of the adjustment block and reduces rotational friction. At the same time, a hexagonal hole is opened at the center of the first adjustment block.

Under the coordinated rotation of the first and second adjusting blocks, the overall function of the reversing mechanism is realized.

[0012] As a preferred technical solution of this utility model, a groove is formed on the contact surface of the first adjusting block and the second adjusting block, and a pair of limiting bolts are fixedly connected to the surface of the first support frame. The limiting bolts slide to connect the first adjusting block and the second adjusting block, and the grooves of the first adjusting block and the second adjusting block are diagonally distributed.

[0013] Using the above technical solution, grooves are formed on the contact surfaces of the first adjusting block and the second adjusting block, and a pair of limiting bolts are fixedly connected to the surface of the first support frame. The limiting bolts slidably connect the first adjusting block and the second adjusting block, and the grooves of the first adjusting block and the second adjusting block are diagonally distributed.

[0014] As a preferred technical solution of this utility model, a first fixed frame is fixedly connected above the first support frame, and a first limiting block and a second limiting block are fixed to the side of the first support frame by a first bolt;

[0015] Using the above technical solution, a first fixing frame is fixedly connected above the first support frame. The first fixing frame is used to further fix the components. The first limiting block and the second limiting block are fixed to the side of the first support frame by the first bolt. This fixing method is convenient for installation and disassembly and facilitates later maintenance.

[0016] As a preferred technical solution of this utility model, a pin is fixedly connected to the lower part of the first fixing plate, the first fixing plate is engaged with the second support frame through the pin, and a slot is opened on the upper part of the second support frame, the slot matching the pin;

[0017] Using the above technical solution, a pin is fixedly connected to the bottom of the first fixing plate. The first fixing plate is engaged with the second support frame through the pin, and a slot is opened on the top of the second support frame. The slot matches the pin.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-10 The present invention provides a modular anti-fall guide rail assembly with rotary steering adjustment, embodiment one.

[0038] For details, please refer to the following: Figures 1-6 It includes a first support frame 1, a first fixed frame 2, a first limiting block 4, a second limiting block 5, a first adjusting block 6, a second adjusting block 7, a transmission bolt 8, a limiting bolt 9, and a first bolt 10;

[0039] The reversing mechanism installed above the first support frame 1 is a key part for realizing the flexible steering of the guide rail assembly. The reversing mechanism is composed of a first adjusting block 6, a second adjusting block 7, a transmission bolt 8, and a limit bolt 9. The first adjusting block 6 and the second adjusting block 7 transmit power through the hexagonal transmission bolt 8. When it is necessary to adjust the direction of the guide rail assembly, the transmission bolt 8 is rotated, which will drive the first adjusting block 6 and the second adjusting block 7 to rotate synchronously. At the same time, the limit bolt 9 is inserted into the guide rail on the bottom surface of the first adjusting block 6 and the second adjusting block 7 to play a limiting role, thereby accurately completing the orientation and reversing function, allowing the guide rail assembly to change the guiding direction according to actual needs.

[0040] A guide rail mechanism is provided on the side of the first adjusting block 6. This mechanism includes a first fixed frame 2, a first limiting block 4 and a second limiting block 5. When the first adjusting block 6 completes the turning action, it can serve as a connecting part to ensure the continuity of its own movement.

[0041] The first support frame 1 adopts a cross-shaped structure. This unique shape design brings many advantages to the entire guide rail assembly. The cross-shaped structure gives the first support frame 1 good stability and strong load-bearing capacity. Like a solid foundation, it can steadily support the entire guide rail assembly in complex and ever-changing working environments, ensuring its normal operation. Above the first support frame 1, the first adjusting block 6 is rotatably connected. The top of the first adjusting block 6 is designed with a circular structure. The biggest advantage of the circular structure is that it facilitates the rotation of the adjusting block. During the rotation, the circular structure can effectively reduce frictional resistance, making the rotation of the adjusting block smoother. In addition, a hexagonal hole is opened at the center of the first adjusting block 6. This hexagonal hole perfectly matches the hexagonal structure of the transmission bolt 8. When the transmission bolt 8 rotates, the hexagonal structures fit together and can work closely together to achieve efficient power transmission and ensure the stable operation of the reversing mechanism.

[0042] The first adjusting block 6 is connected to the second adjusting block 7 via a transmission bolt 8. The lower part of the second adjusting block 7 is designed with a rectangular structure. Compared with other shapes, the rectangular structure increases the contact area with the first support frame 1. The larger contact area means a more stable connection, just like adding multiple support points, which improves the stability of the connection between the second adjusting block 7 and the first support frame 1. Moreover, the second adjusting block 7 and the first support frame 1 are rotatably connected. In this way, when the first adjusting block 6 and the second adjusting block 7 work together, they can rotate synchronously and jointly realize the overall function of the reversing mechanism, ensuring that the guide rail assembly can smoothly complete the steering adjustment action.

[0043] Grooves are formed on the contact surfaces of the first adjusting block 6 and the second adjusting block 7. Meanwhile, a pair of limiting bolts 9 are fixedly connected to the surface of the first support frame 1. The pair of limiting bolts 9 are slidably connected to the first adjusting block 6 and the second adjusting block 7, and the grooves of the first adjusting block 6 and the second adjusting block 7 are diagonally distributed. This carefully designed structure is of great significance because it can precisely limit the rotation angle and position of the first adjusting block 6 and the second adjusting block 7. When the guide rail assembly is adjusted for steering, the adjusting block can only rotate according to the trajectory defined by the limiting bolts 9 and the grooves, thereby greatly improving the accuracy and reliability of reversing and avoiding guide rail assembly failure caused by uncontrolled rotation of the adjusting block.

[0044] Above the first support frame 1, the first fixed frame 2 is fixedly connected. The first fixed frame 2 is like an auxiliary support platform. On the side of the first support frame 1, the first limiting block 4 and the second limiting block 5 are fixed by the first bolt 10. The biggest advantage of using bolt fixing is that it is easy to install and disassemble. When maintaining the guide rail assembly in the later stage, if a certain part has a problem, the maintenance personnel can easily unscrew the bolt and replace or repair the corresponding part.

[0045] Example 2

[0046] For details, please refer to the following: Figures 7-8 The difference between this embodiment and the first embodiment is that: the first fixing plate 12 is fixedly connected to the lower part of the pin 13, the first fixing plate 12 is engaged with the second support frame 11 through the pin 13, and the second support frame 11 has a slot 14 on the upper part, the slot 14 and the pin 13 are matched.

[0047] The first fixing plate 12 is fixedly connected to the lower part of the pin 13. The first fixing plate 12 is engaged with the second support frame 11 through the pin 13. The second support frame 11 has a slot 14 on the upper part, which matches the pin 13. This engaging connection method realizes the quick connection and disassembly between the first fixing plate 12 and the second support frame 11, which reflects the modular design concept of this guide rail assembly and makes it convenient to replace or combine different components according to actual needs.

[0048] Example 3

[0049] For details, please refer to the following: Figures 9-10 A guide groove 16 is provided on the side of the third bearing plate 15. The guide groove 16 has a T-shaped structure. The third adjusting block 3 is bolted to the center of the third bearing plate 15.

[0050] By simplifying the structure and fixing the third adjusting block 3 with bolts, the reversing efficiency of the third bearing plate 15 can be improved, ensuring the structural strength.
