[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0023] like Figures 1-3 As shown, the suspended platform wire rope connection system of this utility model includes a fixed lifting mechanism 1, a guide frame 2, a suspended platform 3 and a wire rope 4, wherein the wire rope 4 is connected to the fixed lifting mechanism 1, the guide frame 2 and the suspended platform 3;
[0024] The fixed lifting mechanism 1 includes a Bailey frame 11 and a rope winding device 12, wherein the rope winding device 12 is disposed in the Bailey frame 11;
[0025] The guide frame 2 includes several vertically connected hangers 21. Figure 1 (Taking four as an example), the bracket 21 has several guide wheels 22 on both sides;
[0026] The suspended platform 3 is provided with a connecting kit 31, which includes safety guide wheels 311 and safety locks 312 on both sides of the connecting kit 31.
[0027] The wire rope 4 includes a working rope 41 and two safety ropes 42. The rope winding device 12 is connected to the guide wheel 22 and the safety guide wheel 311 through the working rope 41. The Bailey frame 11 is connected to the safety lock 312 through the safety ropes 42.
[0028] The safety lock 312 is aligned with the guide wheel 22 to form a plane, so as to ensure that the safety lock 312 is activated in time when the tilt angle of the suspended platform 3 reaches the set value and instantly intervenes in the locking state. The locking principle of the safety rope 42 and the safety lock 312 is existing technology.
[0029] This utility model's suspended platform wire rope connection system provides multi-segment guidance for the working rope 41 through the guide wheel 22 of the guide frame 2 and the safety guide wheel 311 of the connection kit 31. The Bailey frame 11 is connected to the safety lock 312 through the safety rope 42 to prevent the suspended platform 3 from falling or tilting, so as to ensure the accurate installation and positioning of the wire rope 4. This system can ensure the precise control of the position of the suspended platform 3, protect the normal use of the wire rope 4, and avoid accidental damage.
[0030] Specifically, the suspended platform 3 includes several horizontally connected upper frames 32, several platform walkways 33, and several platform uprights 34;
[0031] The platform uprights 34 are located on the inner and outer sides of the upper frame 32 and the inner and outer sides of the platform walkway 33 to connect the upper frame 32 and the platform walkway 33.
[0032] The upper frame 32 includes two horizontal bars 321, several reinforcing bars 322, and two bottom connecting bars 323.
[0033] The two crossbars 321 are connected at their middle parts by the reinforcing rod 322, and the ends of the two crossbars 321 are connected by the bottom connecting rod 323, which is located at the bottom of the crossbars 321.
[0034] The connecting kit 31 also includes several pulleys 313, which are mounted on the bottom connecting rod 323. The pulleys 313 act as movable pulleys during the lifting and lowering of the suspended platform, which can reduce the load on the working rope.
[0035] The safety lock 312 is mounted on the platform uprights 34 at both ends of the bottom connecting rod 323, and the safety guide wheel 311 is mounted on the inner side of the upper part of the safety lock 312.
[0036] For ease of installation and disassembly, the pulley 313 is detachably connected to the bottom connecting rod 323, and the safety lock 312 is detachably connected to the platform upright 34. The preferred connection method is bolt connection.
[0037] It should be noted that the safety guide wheel 311, safety lock 312 and pulley 313 of the connecting kit 31 cooperate to form a hanging point. In actual construction, if the position of the hanging point is not fixed, it is easy to cause some wire ropes to be overloaded due to uneven distribution of the hanging points. Therefore, the connecting kit 31 can be set at a fixed position on the suspended platform 3 according to actual needs to reduce the situation of some wire ropes being overloaded due to uneven distribution of the hanging points.
[0038] Regarding the specific structure of the guide frame 2, the hanging frame 21 includes a hanging frame walkway 211 and several hanging frame uprights 212, with the hanging frame uprights 212 located on the inner and outer sides of the hanging frame 211 walkway.
[0039] It should be noted that adjacent hanging brackets 211 in the vertical direction are connected by adjacent hanging bracket uprights 212 in the vertical direction. This connection can be achieved by welding or by introducing intermediate connecting parts. The specific connection methods are existing technologies, and their principles will not be elaborated here.
[0040] To facilitate the installation and adjustment of the guide wheel 22, the guide wheel 22 is detachably connected to the hanging bracket upright 212. The guide wheel 22 and the hanging bracket upright 212 are connected by bolts. For example, the guide wheel 22 and the hanging bracket upright 212 are provided with corresponding threaded holes for bolts to pass through, so as to fix the guide wheel 22 to the hanging bracket upright 212. Bolt connection is a preferred connection method for the guide wheel 22 and the hanging bracket upright 212. In practical applications, other connection methods can also be used.
[0041] Preferably, the guide wheel 22 is located on the outer side of the top end and / or the outer side of the bottom end of the hanging bracket upright 212. One guide wheel 22 can be installed on the outer side of the top end of the uppermost hanging bracket upright 212 and the outer side of the bottom end of the lowermost hanging bracket upright 212 to guide the working rope 41 along the overall height of the guide frame 2. When the guide frame 2 is relatively high, the guide wheel 22 can also be added in the middle to enhance the guiding effect on the working rope 41.
[0042] The Bailey bridge 11 includes an upper suspension beam 111 and a lower suspension beam 112. The upper suspension beam 111 is connected to an I-beam hanging beam 111a, which is connected to the safety lock 312 via a safety rope 42. Preferably, the safety rope 42 is vertically connected to the I-beam hanging beam 111a for higher reliability. Specifically, the safety rope 42 is connected to the I-beam hanging beam 111a by wrapping or perforating, and the rope end of the safety rope 42 is locked with a U-bolt. To prevent the bottom ends of the two safety ropes 42 from tangling together, a weight block 421 is connected to the bottom end of each safety rope 42. Preferably, the weight block 421 weighs 25 kg. During the lifting and lowering of the suspended platform 3, the weight block 421 is on the ground and not suspended in the air, and the safety ropes 42 should not be too long to avoid tangling.
[0043] The I-beam hanging beam 111a can be connected to the upper suspension beam 111 by bolts, or a connection method conforming to design standards, such as welding connection, can be adopted according to actual needs.
[0044] The rope winding device 12 includes a frame body 121 mounted on the lower suspension beam 112 and a winch 122 mounted on the frame body 121. The rope winding device 12 is located in the middle of the lower suspension beam 112 to ensure that the Bailey bridge 11 is subjected to balanced forces.
[0045] The frame body 121 is provided with frame guide wheels 121a on both sides, and the winch 122 is connected to the frame guide wheels 121a, guide wheels 22 and safety guide wheels 311 through the working rope 41.
[0046] The frame guide wheel 121a, guide wheel 22 and safety guide wheel 311 are located on the same straight line to ensure the verticality of the working rope 41. The connection between the safety rope 42 and the I-beam hanging beam and the safety lock are located on the same straight line to ensure the verticality of the safety rope 42.
[0047] To further ensure safety, anti-derailment devices (not shown in the figure) are installed on the hanging bracket upright 212 and platform upright 34. The working principle of the anti-derailment device is based on existing technology, such as a mechanical wire rope anti-derailment device, which mainly consists of a locking mechanism, a spring mechanism, and a sensor. When the wire rope experiences a decrease in tension or loosening, the sensor can detect the signal and trigger the locking mechanism to prevent the wire rope from further slipping out.
[0048] The following describes the main construction methods and steps of the suspended platform wire rope connection system of this utility model:
[0049] 1. Install the rope winding device 12 on the lower suspension beam 112 of the Bailey bridge 11;
[0050] 2. Align the rope drum of the winch 122 with the connecting kit 31 (i.e., the hanging point) on the suspension platform 3;
[0051] 3. Install the guide wheel 22 on the hanging frame upright 212, and install the anti-rope detachment device on the hanging frame upright 212 and the platform upright 34;
[0052] 4. Install the safety lock 312 and safety guide wheel 311 on the platform upright 34;

[0056] 2) Install the working rope:
[0057] First, untie the fixed end of the working rope 41, and after passing through the frame guide wheel 121a, extend vertically downward along the outside of the hanging frame 21, and pass through the guide wheel 22 and the safety guide wheel 311 to reach the suspended platform 3, and pass through the pulley 313.
[0058] Next, after the working rope 41 reverses its direction, it goes vertically upward along the inner side of the bracket 21, and passes through the safety guide wheel 311 and the guide wheel 22 in sequence, to the winch position, where the working rope 41 is connected to the fixed end of the winch 122.
[0059] Finally, the tension sensors are installed in parallel (parallel connection provides dual protection).
[0060] 6. Check the installation of the wire rope 4 to ensure that the safety rope 42 is properly matched with the I-beam hanging beam 111a and the safety lock 312, and to ensure that the working rope 41 is properly matched with the guide wheel 22, the safety guide wheel 311 and the pulley 313.
[0061] In summary, the wire rope connection system for the suspended platform of this utility model provides multi-segment guidance for the working rope 41 through the guide wheel 22 of the guide frame 2 and the safety guide wheel 311 of the connection kit 31. The Bailey frame 11 is connected to the safety lock 312 through the safety rope 42 to prevent the suspended platform 3 from falling or tilting, thereby ensuring accurate installation and positioning of the wire rope 4. This ensures precise control of the position of the suspended platform 3, protects the wire rope 4 for normal use, and avoids accidental damage. The wire rope connection system for the suspended platform of this utility model also includes the pulley 313 and the frame guide wheel 121a. By setting multiple guides for positioning, it avoids phenomena such as positional deviation, derailment, and jamming of the wire rope 4. The working rope 41 and the safety rope 42 run from both sides of the hanging frame 21, and with the arrangement of multiple pulleys, it ensures the stability of the suspended platform 3.
[0062] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
