Description
Technical field
The utility model relates to a kind of protective fence door lock, particularly a kind of gravity type boat davit protective fence door lock.
Background technology
For ensureing ground staff's safety, building hoist ground protective fence must arrange machinery and electric interlocking installation.The mechanical lock of current all building hoist ground protective fence all have employed spring as the element keeping mechanical lock coupling mechanism force, and its complex structure, fault rate is higher.
Utility model content
In order to solve the problem, the utility model provides a kind of gravity type boat davit protective fence door lock, comprise eccentric swinging arm, tourelle, lock ring, lock pin and mounting bracket, one end of described eccentric swinging arm is provided with tourelle, the other end is welded with metal lock ring, described eccentric swinging arm is arranged on one end of mounting bracket by the first rotating shaft, the other end of described mounting bracket welds with the upper end of protective fence door, distance between described first rotating shaft and tourelle is less than the distance between the first rotating shaft and metal lock ring, and described metal lock ring weight is greater than the weight of described tourelle, described first rotating shaft and the cage vertical distance of hitting between plate are less than the distance between tourelle and the first rotating shaft, the top of described protective fence door is provided with cylindric lock pin, and described cotter diameter is less than described metal lock ring internal diameter, and the distance between described lock pin axle center and the first rotating shaft core is equal with the distance between the metal lock ring center of circle and the first rotating shaft core.
Described tourelle is roller, and described roller is socketed in eccentric swinging arm one end by the second rotating shaft.
Described cage hits plate and tourelle contact jaw is inclined-plane.
The beneficial effects of the utility model are: 1, structure of the present utility model is simple, reasonable in design, can effectively lock; 2, by arranging eccentric swinging arm, when protective fence door needs to close locking, this eccentric swinging arm metal lock ring weight is greater than roller weight, under gravity, metal lock ring can nature sink until lock with the lock pin on protective fence door, without any need for power can complete locking; 3, by arranging roller, and the first rotating shaft and the cage vertical distance of hitting between plate is less than the distance between roller and the first rotating shaft, cage is made to hit plate when decline, roller end can decline the locking state opened between lock ring and lock pin, and roller can hit on plate at cage and rolls, reduce friction drag.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model;
In figure, 1, mounting bracket; 2, eccentric swinging arm; 3, metal lock ring; 4, tourelle; 5, lock pin; 6, protective fence door; 7, cage hits plate; 8, the first rotating shaft; 9, the second rotating shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
As shown in Figure 1, a kind of gravity type boat davit protective fence door lock of the present utility model, comprise eccentric swinging arm 2, tourelle 4, lock ring 3, lock pin 5 and mounting bracket 1, one end of eccentric swinging arm 2 is provided with tourelle 4, the other end is welded with metal lock ring 3, eccentric swinging arm 2 is arranged on one end of mounting bracket 1 by the first rotating shaft 8, the other end of mounting bracket 1 welds with the upper end of protective fence door 6, distance between first rotating shaft 8 and tourelle 4 is less than the distance between the first rotating shaft 8 and metal lock ring 3, and metal lock ring 3 weight is greater than the weight of tourelle 4; First rotating shaft 8 and the cage vertical distance of hitting between plate 7 are less than the distance between tourelle 4 and the first rotating shaft 8; The top of protective fence door 6 is provided with cylindric lock pin 5, and lock pin 5 diameter is less than described metal lock ring 3 internal diameter, and the distance between lock pin 5 axle center and the first rotating shaft 8 axle center is equal with the distance between metal lock ring 3 center of circle and the first rotating shaft 8 axle center.
Tourelle 4 is roller, and roller is socketed in eccentric swinging arm 2 one end by the second rotating shaft 9.It is inclined-plane that cage hits plate 7 with tourelle 4 contact jaw.
In use, eccentric swinging arm 2 installs one end of metal lock ring 3 under gravity, all the time be flapped toward protective fence door 6, now the metal lock ring 3 of eccentric swinging arm 2 front end just in time entangles the lock pin 5 at protective fence door 6 top, so protective fence door 6 is in locking states.When cage moves to ground downwards, the cage be arranged on cage hits the roller 4 that plate 7 can knock eccentric swinging arm 2 rear end, and eccentric swinging arm 2 is rotated, now eccentric swinging arm 2 front end is lifted, lock ring 3 leaves lock pin 5, and protective fence door 6 is in released state, and now protective fence door 6 can manually upwardly open.In protective fence door 6 opening, due to the restriction of electric interlocking installation, cage can not start.After protective fence door 6 is closed, cage can upwards start, along with cage upwards runs, cage hits plate 7 and leaves roller 4 on eccentric swinging arm 2, eccentric swinging arm 2 is flapped toward protective fence door 6 side under gravity, the metal lock ring 3 of eccentric swinging arm 2 front end is inserted in the lock pin 5 at protective fence door 6 top automatically, and protective fence door 6 is in locking states again.
Set forth a lot of detail in the above description so that fully understand the utility model.But above description is only preferred embodiment of the present utility model, the utility model can be much different from alternate manner described here to implement, and therefore the utility model is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solutions of the utility model ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solutions of the utility model protection.
