Description
Technical field
The utility model relates to a kind of mechanical car stopping device technology, specifically, relates to a kind of mechanical anti-falling open in usual safety hook that falls.
Background technology
According to the requirement of the relevant laws and regulations of country and industry, all lifting cross sliding type mechanical parking equipments all must be equipped with the release mechanism that prevents that sweep from falling, and can not fall at the chain or the wire cable rupture back wall that promote vehicle-containing guaranteeing.What the falling proof device of present domestic most of mechanical parking equipment adopted all is the structure that electromagnet adds the machinery hook, this project organization cost is higher, and also has a significant disadvantages, that is exactly that the circuit relevant with electromagnet is many, this just causes the trouble point that may break down many, according to experience in the past, the fault that the lifting cross sliding type mechanical parking equipment of electromagnet falling proof device is installed has very most of safety hook with electromagnet relevant.Also just be based on the more reason in trouble point that electromagnet exists, domestic mechanical parking equipment manufacturers design has gone out the fall arrest safety hook of Purely mechanical structure, thereby has solved the problem that fault that the electromagnet safety hook exists takes place frequently.But owing to the mechanical type hook great majority employing that designs at present all is the normally closed type structure, that is to say that safety hook is to be in closure state when vehicle-containing is static, in the time of the vehicle-containing lifting, by the associated mechanisms on the vehicle-containing safety hook is removed, thereby made equipment be in normal operation.But also there is a potential safety hazard in this structure, machinery hook on some angles of vehicle-containing is owing to installing or using reason to cause and can't normally open in case that is exactly, vehicle-containing an angle will occur and caught on and can not descend so, and other three phenomenons that the angle normally descends, when this accident takes place, if administrative staff in time do not find, the danger that the automobile on the vehicle-containing is toppled over probably occurs.
It is the patent of CN201386413Y that Patent Office of the People's Republic of China has announced notification number on January 20th, 2010, and name is called: parking sweep mechanical type safety hook device, this device comprise the parking apparatus fixed frame, hang lifting appliance, the safety hook device; The safety hook device is made up of clevis arm, shifting block, shifting block support, wherein shifting block is made up of driving lever, pole socket, spacing ring, the shifting block support is fixed on suspension centre supporting base groove upper surface, clevis arm is made up of positive and negative two guiding surfaces on wedge shape gib head, arm body and the arm body, clevis arm is hinged on the fixed frame, on the upper and lower motion track of driving lever that positive and negative two guiding surfaces of clevis arm are positioned at shifting block.This device mainly is to concern by the position that moving between driving lever and the clevis arm regulated between gib head and the parking sweep, when lifting steel wire or chain sling are intact, driving lever side-play amount on pole socket is less, it is far away that driving lever pushes away the arm body, and gib head just can not contact with the parking sweep, when lifting steel wire or chain sling disconnect suddenly, the side-play amount of driving lever on pole socket is bigger, it is nearer to push away the arm body, and gib head does not leave on the upright position of parking sweep fully, and gib head hooks the parking sweep.This device security performance is better, but required component are more, and mostly is non-type, irregular, and structure is comparatively complicated.
Summary of the invention
The utility model has mainly solved: in the general lift-sliding mechanical parking equipment, because the general employing of falling proof device all is the structure that electromagnet adds the machinery hook, cost is higher, and there is certain security hidden trouble in other machinery hooks, provide a kind of simple in structure, the mechanical anti-falling open in usual that cost the is low safety hook that falls.
The technical solution adopted in the utility model is: a kind of mechanical anti-falling open in usual safety hook that falls, comprise hook coupler body and hanging block, the described mechanical anti-falling open in usual safety hook that falls is installed on the loading equipment, hook coupler body afterbody is provided with the hook base, hook coupler body afterbody is hinged with the hook base, the hook base is fixed on the top of the agent structure of loading equipment, hanging block is fixed on the support board of loading equipment and is corresponding with the hook coupler body, the middle part of hook coupler body is provided with a push rod, one end of push rod is fixed on the hook coupler body, is used for the steel wire of lifting or chain on the other end of push rod and the loading equipment and offsets and make and link up with the coupler body head and hanging block is spaced a distance.
The hook coupler body is fixed on the loading its upper side by the hook base, a push rod is fixed at the middle part of hook coupler body, the steel wire or the chain that are used for lifting on the front end of push rod and the loading equipment offset, and make the hook coupler body tilt, when support board rose, the hook coupler body can not hook the hanging block that is installed on the support board; After support board rises to certain altitude, when being used for the steel wire of lifting or chain on the loading equipment and rupturing suddenly, because hook coupler body afterbody is rotatably connected with the hook base, the hook coupler body can be under the effect of itself gravity, return to the nature plumbness, support board carries in the process of whereabouts, and the hanging block that is installed on the support board can be hooked in hook coupler body limit, prevents that support board lands.
As preferably, all have the installing hole that is used to install bearing pin on hook coupler body afterbody and the hook base, hook coupler body afterbody and hook base are hinged by bearing pin, connect by bearing pin, and the rotation of hook coupler body is more flexible, is convenient to hook and resets.
As preferably, push rod is provided with a sliding seat outward, and an end of sliding seat is connected with push rod, and the steel wire or the chain that are used for lifting on the other end of sliding seat and the loading equipment offset.The smooth surface of sliding seat, and contact area is big, with loading equipment on when being used for the steel wire of lifting or chain and offseting, frictional force and pressure all are reduced, and are of value to the operation of device.
As preferably, be provided with elastic component between hook coupler body afterbody and the hook base.Thing tilts before accident takes place because of the hook coupler body, and after accident takes place, for avoiding loss, need reset timely, and the connection by elastic component can allow the hook coupler body in time or the resetting of acceleration.
As preferably, elastic component is a spring, and spring is the simplest, and elasticity is better, and is convenient and practical.
The beneficial effect that the utility model is obtained: simple in structure, required component are less, and cost is lower, are easy to processing and popularization; Can improve the safety factor of loading equipment operation.
