Description

Technical Field

[0001] The utility model relates to a gravity suspension anti-dropping mechanism, in particular to a safety anti-dropping padlock mechanism. Background Art

[0002] Existing automation equipment often involves mechanisms for lifting and lowering loads and maintaining suspension after they are in place. Traditional suspension and holding mechanisms generally rely on the reverse force of a gear set or the pressure of a cylinder to keep it in a loaded state. However, as the loading time increases, it is easy to cause gear set reversal, cylinder deflation, etc., which in turn poses a safety hazard to the motion mechanism or actuator. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a safety anti-dropping padlock mechanism with an anti-dropping locking function to prevent the load-bearing mechanism from slipping and improve the safety and reliability in view of the deficiencies in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0005] A safety anti-drop padlock mechanism comprises a frame, a lifting frame and a driving mechanism for driving the lifting frame to move up and down, a backstop plate is fixed to the side of the lifting frame, a crossbeam is fixed to the side of the frame, a cylinder is provided on the crossbeam, a telescopic rod of the cylinder is transmission-connected with a safety lock shaft, and the cylinder is used to drive the safety lock shaft to move to the bottom of the backstop plate or move out from the bottom of the backstop plate.

[0006] Preferably, the crossbeam is a vertical plate-shaped crossbeam.

[0007] Preferably, a shaft sleeve seat is fixed on the crossbeam, the cylinder is fixed to the end of the shaft sleeve seat, and one end of the safety lock shaft is arranged in the shaft sleeve seat.

[0008] Preferably, a floating connector is provided in the shaft sleeve seat, and the floating connector is connected between the telescopic rod of the cylinder and the safety lock shaft.

[0009] Preferably, the outer side wall of the safety lock shaft is provided with a groove portion for the retaining plate to be inserted into.

[0010] In the safety anti-slip padlock mechanism disclosed by the utility model, the driving mechanism drives the lifting frame to move up and down, and the lifting frame can carry loads or carry an actuator. When the lifting frame is located and moves to a lower position, the cylinder drives the safety lock shaft to retract, and the safety lock shaft moves out from under the stop plate. At this time, the safety lock shaft does not interfere with the up and down movement of the stop plate. When the lifting frame rises to a higher position and remains in a suspended state, the cylinder drives the safety lock shaft forward to move the safety lock shaft to under the stop plate. In this state, even if the lifting frame slides down due to the load, the stop plate can be clamped on the safety lock shaft, thereby playing a safety anti-slip effect. Compared with the prior art, the utility model has an anti-slip locking function, which can effectively prevent the load-bearing mechanism from slipping, thereby improving the safety and reliability of the automation equipment.

[0015] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0016] The utility model discloses a safety anti-drop padlock mechanism, combined with Figures 1 to 4 As shown, it includes a frame 1, on which a lifting frame 2 and a driving mechanism 3 for driving the lifting frame 2 to move up and down, a backstop plate 4 is fixed to the side of the lifting frame 2, a crossbeam 5 is fixed to the side of the frame 1, a cylinder 6 is provided on the crossbeam 5, and a telescopic rod of the cylinder 6 is transmission-connected with a safety lock shaft 7, and the cylinder 6 is used to drive the safety lock shaft 7 to move to the bottom of the backstop plate 4 or move out from the bottom of the backstop plate 4.

[0017] In the above structure, the driving mechanism 3 drives the lifting frame 2 to move up and down, and the lifting frame 2 can carry loads or carry actuators. When the lifting frame 2 is located and moves to a lower position, the cylinder 6 drives the safety lock shaft 7 to retract, and the safety lock shaft 7 moves out from under the stop plate 4. At this time, the safety lock shaft 7 does not interfere with the up and down movement of the stop plate 4. When the lifting frame 2 rises to a higher position and remains in a suspended state, the cylinder 6 drives the safety lock shaft 7 forward to move the safety lock shaft 7 to under the stop plate 4. In this state, even if the lifting frame 2 slides down due to the load, the stop plate 4 can be clamped on the safety lock shaft 7, thereby playing a safety anti-slip effect. Compared with the prior art, the utility model has an anti-slip locking function, which can effectively prevent the load-bearing mechanism from slipping, thereby improving the safety and reliability of the automation equipment.

[0018] As a preferred method, see Figure 1 The cross beam 5 is a vertical plate-shaped cross beam. Specifically, the cross beam 5 is fixed between two legs of the frame 1.

[0019] Combination Figures 1 to 3 As shown, in order to facilitate the installation of the cylinder 6 and provide a movable space for the safety lock shaft 7, in this embodiment, a shaft sleeve seat 8 is fixed on the crossbeam 5, the cylinder 6 is fixed to the end of the shaft sleeve seat 8, and one end of the safety lock shaft 7 is arranged in the shaft sleeve seat 8.

[0020] In the above structure, the sleeve seat 8 is fixed to the crossbeam 5 through a flange, and the safety lock shaft 7 can slide forward and backward relative to the sleeve seat 8. In actual application, the cylinder 6 drives the safety lock shaft 7 forward or backward through the telescopic rod.

[0021] As a preferred method, combined with Figure 3 and Figure 4 As shown, a floating connector 9 is provided in the shaft sleeve seat 8, and the floating connector 9 is connected between the telescopic rod of the cylinder 6 and the safety lock shaft 7. The floating connector 9 is movably connected between the telescopic rod of the cylinder 6 and the safety lock shaft 7, and the floating connector 9 plays a push-pull transmission role between the two. By setting the floating connector 9, this embodiment can effectively avoid jamming, unsmooth telescopic movement, etc. caused by processing and installation errors, thereby ensuring the reliable movement of the safety anti-drop padlock mechanism.

[0022] On this basis, the outer wall of the safety lock shaft 7 is provided with a groove portion 70 for the backstop plate 4 to be inserted into. The width of the groove portion 70 is slightly greater than the thickness of the backstop plate 4. When the lifting frame 2 is forced to sink, the backstop plate 4 can be inserted into the groove portion 70. Based on the limiting relationship between the two, the backstop plate 4 can be stably and reliably locked and restricted.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
