Abstract
The utility model discloses an unhooking-preventing device, relating to the technical field of unhooking-preventing safety. The unhooking-preventing device adopts the following structure: a steel plate is installed at an opening of a hood body; one end of the steel plate can rotate at a hook head of the hood body; the other end of the steel plate is connected with a square tube capable of rotating along the surface of the steel plate; and the square tube is sleeved at a hook tip of the hook head. The unhooking-preventing device has the advantages of simple structure, easiness for processing, good safety performance, wide application range and suitability for popularization.
Description
Technical field
The utility model relates to the lock hook technical field, specifically is a kind of lock hook device, can be applicable to the various weight-lifting equipments of every profession and trade, need in the processing of aluminium sheet band and steel plate band to be specially adapted to the weight-lifting equipment with " C type hook " lifting coiled material.
Background technology
Driving (weight-lifting equipment) in use tends to because the unhook phenomenon appears in breakdown of equipment or misoperation, the driving unhook damage thing of can hurting sb.'s feelings, and abnormally dangerous, it is very necessary to increase a lock hook device therefore for driving.
Travelling crane hook carried lock hook device (like Fig. 1) in the past, because of simple and crude and poor quality can damage very soon, and must live steel plate with a hand when using; Hang again into and deviate from suspender, be extruded into hand because of carelessness through regular meeting, abnormally dangerous. particularly in aluminium sheet band and steel plate band processing enterprise, need with " C type hook " lifting coiled material; " C type hook " just can't be hung into suspension hook; The lock hook device of must dismantling could use, and has potential safety hazard, and the impassabitity safety check.Not only because suspender work but also very frequent is changed in driving, thus be necessary to the lock hook device improve, perfect, it is simple, safe and reliable that the structure of driving lock hook device will be tried one's best, and use wide.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of lock hook device, safe and handled easily.
The utility model is realized with following technical scheme: a kind of lock hook device; At the opening part of coupler body one steel plate is installed; One end of described steel plate can be in the rotation of the gib head place of coupler body; The other end is connected with can be along steel plate rectangular tube in axial sliding, and described rectangular tube is sleeved on the bill place of coupler body.
The beneficial effect of the utility model is: simple in structure, easy processing, and safety performance is good, and range of use is extensive, is fit to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a place where troops were originally stationed trip mechanism structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is that steel plate is connected scheme drawing with rectangular tube.
Among the figure: 1, steel plate, 11, mounting hole, 2, screw rod, 3, spring shim, 4, rectangular tube, 5, anchor ear, 6, spring.
The specific embodiment
As shown in Figure 1; Steel plate 1 withstands on the hook under the effect of spring 6, when unloading " C type hook ", need pin steel plate 1 inward with hand always, is easy to be extruded into hand like this; And steel plate 1 is movable and depart from the hook tip about easily after with a period of time, thereby lose protective effect.
As shown in Figures 2 and 3; The lock hook device is at the opening part of coupler body one steel plate 1 to be installed; One end of described steel plate 1 can be in the rotation of the gib head place of coupler body, and the other end is connected with can be along the rectangular tube 4 of surface of steel plate rotation, and described rectangular tube 4 is sleeved on the bill place of coupler body.
As shown in Figure 4, described steel plate 1 adopts the steel plate that has bending, and an end of steel plate is provided with mounting hole 11, at the gib head place of coupler body one screw rod 2 is installed laterally, is installed on the screw rod 2 with the end of nut with steel plate through mounting hole; Steel plate 1 can be around screw rod 2 rotations; Between steel plate 1 and screw rod 2, be set with spring shim 3.Adopt hinge to be connected between rectangular tube 4 and the steel plate 1; Rectangular tube 4 is installed in the other end of steel plate 1 through bearing pin in addition, and rectangular tube 4 can rotate around bearing pin.
In order not influence gib head intensity, so can not directly screw rod directly be welded on the gib head place, an anchor ear 5 is installed at the gib head place, again on the anchor ear 5 of screw rod welding shown position.
Working process: when needing hook, stir rectangular tube 4 and up rotate and throw off bill, then stir steel plate 1 and be with rectangular tube 4 up to revolve to turn 90 degrees above stopping, can hang into " C type hook " or other suspender, reverse operating is returned to shown position and gets final product then.When driving work, rectangular tube is enclosed within the hook tip, can prevent that steel plate from departing from the hook tip.When unloading " C type hook " or other suspender; Earlier upwards folding its disengaging hook tip that makes of square ring; To make steel plate then be the axle center with the screw rod in its plane, place left or move right and rest on about 90 degree; The effect of elastomeric pad 3 is exactly to increase damping, makes the steel plate can be owing to self gravitation falls after rise when rotating to arbitrary height.When unloading " C type hook ", can remove to contact steel plate more like this without hand, thus the danger of having avoided crowded hand etc. to occur.
