Abstract
The utility model discloses a rail mounted hoist stopper, including the lifting mechanism, the lifting mechanism is connected with the promotion crank, promotes the crank and is connected with the main shaft of dress on the organism, and the main shaft is connected with stopper drive mechanism, and stopper drive mechanism connects the stopper, and the main shaft is connected with the drag hook connecting piece, sets up drag hook mechanism in the near side of drag hook connecting piece. The utility model discloses rational in infrastructure easy operation, maintenance convenience, braking are reliable, effectual, long service life.
Description
Technical field:
The utility model relates to a kind of inhibiting device of hoisting crane.
Background technology:
The locomotive crane of outdoor work, particularly harbour, are often blown away, blow down by strong wind easily, even blow to Jiang Haizhong, thereby cause enormous economic loss when unmanned operation is not taked measures necessary again with locomotive crane.Similar reason occurring is; Unattended, when hoisting crane stops at a certain position, when sweeping strong wind, especially wind-force is bigger, and hoisting crane is subjected to a certain side force, because of force of rolling friction between hoisting crane wheel and guide rail less, when wind-force acquires a certain degree, hoisting crane is walked along guide rail, and in case walking then produces acceleration/accel under the effect of wind-force, walk faster and faster, and when going to tail track, because huge inertia, thereby hoisting crane is toppled over.In order to prevent the generation of this type of accident, many users adopt the most original method, and after the end of job was shut down, artificial added a voussoir between wheel and guide rail, and this method had both bothered also unreliable, can not reach the purpose of safety guard-safeguard.Also there are some users adopt mechanical brake device (comprising Japanese import) now, this device clamps in orbit by spring force, pushed open by hydraulic efficiency gear during the hoisting crane walking, it prevents that wind-force from promoting hoisting crane and moving the friction that is produced by the spring gripping power fully, so its braking force can not be very big again, the opposing party is in order to push spring force open, will very big hydraulic thrust, so complex structure, energy consumption is big, it is also unreliable to brake, and is out of order easily.
Summary of the invention:
The purpose of this utility model is to provide a kind of rational in infrastructure, locomotive crane limiting device that result of use is good.
Technical solution of the present utility model is:
A kind of locomotive crane limiting device, comprise lifter, its feature: lifter is connected with lift crank, lift crank is connected with main shaft on being contained in body, main shaft is connected with the limiting stopper transmission device, the limiting stopper transmission device connects limiting stopper, and main shaft is connected with the drag hook attaching parts, at the nearside of drag hook attaching parts drag hook mechanism is set.
The limiting stopper transmission device comprises and main shaft bonded assembly main crank that main crank is connected with connecting rod, and connecting rod is connected with double crank, and double crank connects slide block by the little axle of slide block, and slide block is connected with the limiting stopper connecting panel.Drag hook mechanism comprises drag hook, and the drag hook below is provided with electromagnet.Main shaft is connected with handle.
The utility model rational in infrastructure simple to operate, easy to maintenance, the braking reliable, effective, long service life.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A view of Fig. 1.
The specific embodiment:
A kind of locomotive crane limiting device, comprise lifter 1, lifter 1 is connected with lift crank 2, lift crank 2 is connected with main shaft 4 on being contained in body 3, main shaft 4 is connected with main crank 5, main crank 5 is connected with connecting rod 6, connecting rod 6 is connected with double crank 7, double crank 7 connects slide block 9 by the little axle 8 of slide block, slide block 9 can float in double crank 7, can guarantee that limiting stopper 11 can fit with wheel arc surface and orbital plane simultaneously, wedging, slide block 9 is connected with limiting stopper connecting panel 10, and limiting stopper connecting panel 10 connects limiting stopper 11, main shaft 4 is connected with drag hook attaching parts 12, nearside at drag hook attaching parts 12 is provided with drag hook mechanism, and drag hook mechanism comprises drag hook 13, and drag hook 13 belows are provided with electromagnet 14.Main shaft 4 is connected with handle 15, can carry out manual operations in case of necessity.
