Problems solved by technology
[0004] Although the above-mentioned patent can solve the problem of self-resetting of the anti-falling safety device, when it is applied to heavy-weight transportation equipment, it is difficult to ensure the safety of the transportation equipment only by relying on the safety device, which leaves hidden dangers for production safety; at the same time, the transportation equipment with double guide rails Risk of inclination (height difference) on both sides when disturbed by external factors

Embodiment Construction
[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0021] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features that are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0022] Such as figure 1 , figure 2 As shown, an anti-fall safety device 2 with synchronous function is installed on the work platform 1 (or cage), and the work platform 1 rises or falls along the guide rails 101 on both sides. The anti-falling safety device 2 includes a synchronous mechanism 3 coupled with the working platform 1 , a transmission mechanism 4 located in the middle of the synchronous mechanism 3 coupled with the synchronous mechanism 3 , and a safety...

The invention discloses an anti-drop safety device with a synchronizing function. The anti-drop safety device is mounted on an operating platform which ascends or descends along guide rails at the twosides; the anti-drop safety device comprises a synchronizing mechanism connected with the operating platform, a speed change mechanism connected with the synchronizing mechanism, and a safety unit connected with the speed change mechanism; the synchronizing mechanism comprises a central mandrel, a synchronizing shaft and a bearing plate assembly; the synchronizing shaft and the bearing plate assembly are positioned at one side of the central mandrel; one end of the synchronizing shaft is connected with the central mandrel; the other end of the synchronizing shaft is connected with the bearingplate assembly; the bearing plate assembly is connected with the operating platform; and the synchronizing shaft and the bearing plate assembly are symmetrically arranged by taking the central mandrel as center. The anti-drop safety device can prevent transportation equipment from tilting, has a synchronizing function, can force transportation equipment to horizontally ascend, and is safe and reliable.
Description
technical field [0001] The invention belongs to the field of building construction, in particular to an anti-falling safety device with a synchronous function applied to vertical transportation equipment. Background technique [0002] After the PC components prefabricated in the factory are transported to the construction site of the prefabricated building, they need to be transported vertically to the established construction layer again. Some heavy PC components weigh about 15 tons. If there is an accidental fall from a high altitude, the consequences will be disastrous. In order to ensure the stability of the transport equipment, a double guide rail frame is usually used. [0003] Chinese patent 2017109845971 discloses a self-resetting anti-falling safety device, including a safety device gear connected to the work platform, the safety device gear is installed on the rotating shaft, and also includes a friction block bracket and a radial sleeve hanging on the rotating...
