[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0029] Reference Figures 1-2 An embodiment provided by the utility model: an external frame mother rope safety buckle mechanism, comprising a limiting piece 1, the left side of the limiting piece 1 is hingedly connected with a clamping piece 2, the clamping piece 2 can rotate around the hinge joint with the rear end of the limiting piece 1, the limiting piece 1 can be sleeved on the scaffold first, and then the clamping piece 2 is rotated to the position close to the scaffold, at this time, the limiting piece 1 and the clamping piece 2 are mutually close and clamped on the outside of the scaffold, the front side of the clamping piece 2 is provided with a limiting groove 3, and the right side surface of the limiting piece 1 is provided with a groove 4.
[0030] The inside of the groove 4 is provided with a limiting unit, the limiting unit comprises a limiting rod 41, the left side surface of the limiting rod 41 is mutually close to the left side inner wall surface of the groove 4, the left side inner wall of the groove 4 can limit the movement of the limiting rod 41, the limiting rod 41 is arranged in the inside of the groove 4, the left side of the limiting rod 41 is fixedly connected with a screw rod 42, the limiting rod 41 can drive the screw rod 42 to move synchronously when moving, the limiting rod 41 cannot continue to move to the left side in the inside of the groove 4, thereby the movement of the screw rod 42 can be limited, so that the screw rod 42 cannot be pulled to the left continuously, the left end of the screw rod 42 penetrates the limiting piece 1 and the limiting groove 3, the left side of the screw rod 42 is threadedly connected with a nut 43, and the right side surface of the nut 43 is mutually close to the left side surface of the clamping piece 2.
[0031] When the clamping piece 2 is rotated to be clamped on the outside of the scaffold in cooperation with the limiting piece 1, the limiting groove 3 is rotatably sleeved outside the lead screw 42, at this time the worker twists the nut 43 to the outside of the lead screw 42, and rotates the nut 43 to the position close to the left side surface of the clamping piece 2, so as to extrude and limit the clamping piece 2, and apply extrusion force to the clamping piece 2 relative to the side close to the limiting piece 1, so that the whole mechanism tightly wraps the scaffold with appropriate pressure and mode, at this time the limiting piece 1 and the clamping piece 2 generate positive pressure with the scaffold, thereby generating friction force, which is in balance with the external load, and the stable installation is completed.
[0032] With reference to Figures 1-3 The right side surface of the limiting piece 1 is fixedly connected with a fixed plate 5, the fixed plate 5 can be installed on the outside of the scaffold through cooperation of the limiting piece 1, the clamping piece 2 and the limiting unit, the bottom surface of the fixed plate 5 is fixedly connected with a fixed block 6, and the front side surface of the fixed block 6 is provided with a through hole 7. When the steel strand is installed, the steel strand can pass through the through hole 7 to support the steel strand in sections, and disperse the load on the whole mother rope to multiple section points. The diameter of the through hole 7 is greater than the thickness of the fixed plate 5, and the thickness of the fixed plate 5 is less than the diameter of the fixed block 6.
[0033] When selecting the safety lock, a notch matching the fixed plate 5 can be formed on the safety lock, so that the safety lock can pass through the fixed plate 5 directly through the notch when the safety lock is separated from the steel strand. When the worker moves the safety lock to the unloading section point, the notch on the safety lock can be aligned with the fixed plate 5, and the safety lock can be directly moved through the fixed plate 5, without the need to disassemble and move the safety lock as a whole, thereby reducing the safety hazard.
[0034] With reference to Figure 3 The front and rear side surfaces of the fixed plate 5 are fixedly connected with triangular rods 8. When the safety lock is moved to the outside of the fixed plate 5, the notch position can be aligned with the triangular rods 8, and then the safety lock is moved. At this time, the notch can be quickly moved to the fixed plate 5 along the inclined surfaces on the upper and lower sides of the triangular rods 8, thereby reducing the obstruction of the thickness of the fixed plate 5 to the movement of the safety lock, improving the passing efficiency. The upper surface of the fixed plate 5 is fixedly connected with a fixed rod 9, the upper end of the fixed rod 9 is fixedly connected with a guide rod 10, the front and rear ends of the guide rod 10 are downwardly inclined, the front and rear ends of the guide rod 10 are lower than the bottom surface of the fixed plate 5, and the height of the fixed rod 9 relative to the fixed plate 5 is matched with the size of the safety lock. When the safety lock moves to the fixed plate 5, it can be quickly moved upward along the inclined end of the guide rod 10. When the upper end of the safety lock is close to the guide rod 10, the notch of the safety lock can quickly approach the triangular rods 8, thereby further improving the passing efficiency.
[0035] Working principle: after the steel strand is inserted through the through hole 7, the limiting piece 1 is attached to the outer side of the scaffold, and the clamping piece 2 is rotated to the position attached to the scaffold, at this time the limiting groove 3 is rotated to be sleeved outside the lead screw 42, the worker twists the nut 43 to the outside of the lead screw 42, and the nut 43 is attached to the left side surface of the clamping piece 2, so that the clamping piece 2 can be extruded and limited, the extrusion force of the clamping piece 2 relative to the side close to the limiting piece 1 is applied, so that the whole mechanism tightly wraps the scaffold with appropriate pressure and mode, the installation of the buckle mechanism is completed, when the worker moves the safety lock buckle close to the unloading section point, the safety lock buckle can be pulled to move upward along the inclined end of the guide rod 10, so that the gap of the safety lock buckle quickly approaches the triangular rod 8, and the gap passes through the triangular rod 8, at this time the gap can quickly move the fixed plate 5 along the inclined surfaces on both sides of the triangular rod 8, improve the efficiency, avoid the worker to disassemble the safety lock buckle at the unloading section point, cause the existence of the safety risk.
