Referring to fig. 1 to 3, a fall arrest device provided by the present application will now be described. The anti-falling device comprises a support frame 1, a swing frame 3 with one end installed on the support frame 1, a turntable 4 rotatably installed at the other end of the swing frame 3 and a stop frame 5 hinged on the swing frame 3. A plurality of slots 41 for mounting the to-be-supported member 2 are formed in the rotating disc 4 in an annular array, and each slot 41 is arranged along the radial direction of the rotating disc 4. A plurality of abutting blocks 42 are convexly arranged on the peripheral surface of the rotary table 4 at intervals. The stopping frame 5 is used for abutting and matching with the corresponding abutting block 42 and limiting the rotation of the rotary table 4 along the positive direction, so that the external support piece 2 to be supported is hung in the corresponding clamping groove 41, and is used for separating from the abutting with the corresponding abutting block 42 when the support piece 2 to be supported pushes the rotary table 4 to rotate along the negative direction, so that the support piece 2 to be supported is separated from the corresponding clamping groove 41.

In one embodiment, the supporting member 2 may be a vehicle plate suspension loop, which is not limited herein. In some embodiments, the board suspension loop may have an inverted "U" shape, so as to be conveniently mounted in the corresponding slot 41, and thus, the connection with the turntable 4 is achieved.

In the process of ascending the member to be supported 2, the corresponding stopper 42 can guide the member to be supported into the corresponding slot 41; in the process that the supporting piece 2 continues to rise, the stop frame 5 and the corresponding stop block 42 can be matched with the stop turntable 4 to rotate; then, the supporting member 2 descends and extends into the bottom of the clamping groove 41, and at this time, the turntable 4 cannot rotate because the stopping frame 5 is stopped by the corresponding stopping block 42, so that the supporting member 2 is hung on the turntable 4. When the supporting member 2 is unloaded, the supporting member 2 moves upwards and drives the rotating disc 4 to rotate reversely, so that the stop frame 5 and the corresponding stop block 42 are unlocked, and the supporting member 2 can be taken down from the rotating disc 4.

According to the structure, the turntable 4 is rotatably arranged on the swing frame 3, the annular array on the turntable 4 is provided with a plurality of clamping grooves 41, and the peripheral surface of the turntable 4 is convexly provided with a plurality of abutting blocks 42 at intervals. When the supporting piece 2 extends into one of the clamping grooves 41, the stop frame 5 can be matched with the corresponding stop block 42 to stop the rotation of the rotating disc 4, and the supporting piece 2 and the rotating disc 4 are automatically connected and locked; when the member to be supported 2 is removed from the slot 41, the stop frame 5 and the stop block 42 can be unlocked, so that the member to be supported 2 and the rotating disc 4 can be automatically separated. Compared with the traditional electromagnetic hook and power hook, the power hook has the advantages of no need of power-assisted operation, convenient and quick operation, less energy consumption and low cost.

In an embodiment, please refer to fig. 1, as a specific implementation manner of the anti-falling device provided in the present application, a stopping block 42 is disposed between two adjacent slots 41; each abutting block 42 has a first arc-shaped surface 421 connected to the inner side wall of the adjacent one of the slots 41 close to the abutting block 42, and a second arc-shaped surface 422 connected to the inner side wall of the adjacent other one of the slots 41 close to the abutting block 42. Specifically, in two adjacent card slots 41: the inner side wall of one locking groove 41 close to the corresponding resisting block 42 extends towards the direction far away from the center of the rotating disc 4 and is gradually bent for a certain distance towards the circumferential direction of the rotating disc 4 to form the first arc-shaped surface 421; the inner side wall of the other engaging groove 41 close to the corresponding stop block 42 is bent and extended towards the end of the first arc-shaped surface 421 far away from the rotating disc 4 to form the second arc-shaped surface 422. The outer peripheral surface of the rotating disk 4, each first arc-shaped surface 421 and the corresponding second arc-shaped surface 422 enclose the shape of the abutting block 42. With this structure, on the one hand, the first arc-shaped surface 421 can realize effective cooperation with the stopping frame 5 for stopping; on the other hand, the first arc-shaped faces 421 can guide the pieces to be supported 2 into the respective slots 41; on the other hand, the first arc-shaped surface 421 on one resisting block 42 is matched with the second arc-shaped surface 422 on the other resisting block 42, so that the support piece 2 and the stopping frame 5 can be quickly unhooked, and the use reliability of the anti-falling device is improved.

In one embodiment, the number of the abutting blocks 42 may be four or five, and the number of the slots 41 may be arranged in a one-to-one correspondence with the number of the abutting blocks 42. This structure, through experimental simulation analysis reachs, will support the dog 42 and set up and be four or five, can realize treating effective carry between support piece 2 and the carousel 4 and break away from, can not have the fault point, and the reliability is high. Of course, in other embodiments, the number of the stopping blocks 42 and the card slots 41 can be adjusted according to actual needs, and is not limited herein.

In one embodiment, referring to fig. 1, as a specific implementation of the fall-prevention device provided by the present application, the curvature of the first arc-shaped surface 421 is greater than that of the second arc-shaped surface 422. Specifically, the degree of curvature of the first arc-shaped surface 421 is greater than that of the second arc-shaped surface 422. The bending angle of the first arc-shaped surface 421 forms a pushing angle of the to-be-supported member 2, so that the to-be-supported member 2 can smoothly enter the corresponding slot 41. The second arc-shaped surface 422 forms an incision angle with the inner side wall of the corresponding slot 41, so that the to-be-supported member 2 can be conveniently separated from the slot 41. The push-in angle and the cut-in angle are formed through experimental simulation, and are high in precision and good in reliability. With the structure, the first arc-shaped surface 421 with a larger bending degree can effectively improve the stopping effect with the stopping frame 5, and can avoid the separation of the stopping block 42 and the stopping frame 5; but also facilitates the introduction of the member to be supported 2 into the card slot 41. The second arc-shaped surface 422 with the smaller curvature may help to guide the stopper frame 5 to be disengaged from the notch 41, thereby achieving unhooking between the stopper frame 5 and the resisting block 42. In other embodiments, the curvature relationship between the first arc-shaped surface 421 and the second arc-shaped surface 422 can be adjusted according to actual needs, and is not limited herein.

In an embodiment, referring to fig. 1, as a specific implementation manner of the anti-falling device provided by the present application, the anti-falling device further includes a first limiting rod 7 for limiting a rotation angle of the blocking frame 5, the first limiting rod 7 is mounted on the swing frame 3, and the first limiting rod 7 and the blocking frame 5 are disposed at an interval. Wherein, the first limit rod 7 can be arranged along the axial direction parallel to the rotating disc 4. With the structure, when the rotary table 4 rotates reversely, the second arc-shaped surface 422 of the stop block 42 can support the stop frame 5 to rotate, the first limiting rod 7 can limit the stop frame 5 to rotate, and the phenomenon that the stop frame 5 cannot be automatically restored to the initial position due to an overlarge rotation angle is avoided.

The length of the arc-shaped groove can be set according to the angle of the stop frame 5 which needs to swing. When the resisting block 42 resists the rotation of the resisting block frame 5, one end of the arc-shaped groove can resist the limiting rod; when the stop frame 5 reversely rotates under the action of self gravity, the other end of the arc-shaped groove can stop the limiting rod. Therefore, the limit of the rotation angle of the stop frame 5 can be realized through the matching of the two ends of the arc-shaped groove and the limiting rod. In other embodiments, the limitation of the angle of the swing frame 3 may also be achieved by an elastic member, which may be a spring. One end of the elastic element is connected with the swing frame 3, and the other end is connected with the stop frame 5. When the stop frame 5 rotates a certain angle, the elastic member extends, and the rotation of the stop frame 5 can be limited when the maximum extension position is reached. Alternatively, the elastic member is compressed to a maximum compression position to restrict the rotation of the stopper frame 5. Moreover, the elastic piece can pull or push the stopping frame 5 to the initial position in the reverse direction under the action of the elastic force, so that the stopping frame 5 can return quickly.

According to the structure, the rotation angle of the swing frame 3 can be limited through the angle limiting component 6, so that the phenomenon that the operation of the anti-falling device fails due to the fact that the rotation angle of the swing frame 3 is too large can be avoided.

In an embodiment, referring to fig. 1, as a specific implementation of the anti-falling device provided by the present application, the angle limiting component 6 includes a second limiting rod 61 and a third limiting rod 62 that are installed on the supporting frame 1 at intervals, and the swing frame 3 is disposed between the second limiting rod 61 and the third limiting rod 62.

The second limiting rod 61 and the third limiting rod 62 can respectively limit the swing angles of the swing frame 3 in the left direction and the right direction, and the limiting effect is good.

In some embodiments, the supporting frame 1 is provided with an arc-shaped groove, and the swing frame 3 can be provided with a limiting rod extending into the arc-shaped groove. The length of the arc-shaped groove can be set according to the angle of the swing frame 3 needing to swing. The two ends of the arc-shaped groove can be respectively matched with the limiting rods to support the swing frame 3, so that the angle of the swing frame 3 is limited. In other embodiments, the limitation of the angle of the swing frame 3 may also be achieved by an elastic member, which may be a spring. One end of the elastic piece is connected with the supporting frame 1, and the other end is connected with the swing frame 3. When the swing frame 3 swings for a certain angle, the elastic member extends, and the swing of the swing frame 3 can be limited when the elastic member reaches the maximum extension position. Alternatively, the resilient member compresses to limit the swinging motion of the swing frame 3 when it reaches the maximum compressed position. Moreover, the elastic element can pull or push the swing frame 3 to the initial position in the reverse direction under the action of the elastic force, so that the swing frame 3 can return quickly.

With this structure, the positioning guide post 53 is located at one side of the swing frame 3 and can be stopped by the two support plates 31. When the resisting block 42 resists against the resisting frame 5, the positioning guide post 53 rotates through the connecting rod 52 and the rotating shaft 51, and the hooking and unhooking with the corresponding resisting block 42 are realized.
