Abstract

The utility model provides an automatic couple device breaks off relations, still includes the support of being connected with hoisting apparatus including the couple, the support is connected with hook rotate, the couple is including coupler body and counter weight hammer, the end connection of counter weight hammer and coupler body, the weight of counter weight hammer is greater than the weight of coupler body. This automatic couple device breaks off relations is setting up the counter weight hammer on the couple, because of the weight of counter weight hammer is greater than the weight of coupler body, unloads when heavy, and the counter weight hammer rotates downwards the connecting rod through the dead weight reacting phase, and corresponding, the coupler body upwards rotates, and at this moment, the couple is invertd, lifts by crane the thing and breaks away from with the couple to automatically unhook has been realized.

Description

Automatically-unhooked hooking device
Technical field
The utility model relates to a kind of automatically-unhooked hooking device.
Background technology
When transport or mobile heavy objects, as bag greatly, timber, circle base, steel billet, section bar etc., often need to use the suspension hook of suspender to hook displacement of slinging on goods hoist cable, when goods movement puts down to destination, by staff, the hoist cable of suspension hook from goods is taken off again, then suspension hook is hooked on another part goods hoist cable, completes lifting operation so one by one.This operating process need special staff to wait for goods falls rear decoupling device, run into large-scale, easily roll, easily sliding goods time, because measurement of cargo is large, also need during staff's decoupling device to climb down on goods swashes, take a lot of work, require great effort, time-consuming.This mode of operation not only efficiency is low, and needs staff constantly to climb up in operation process to climb down, and pin easily occurs and steps on sliding and the accidents such as tumble injury that fall down.Particularly roll at commute, easily sliding cargo operation time dangerous large, be more prone to accidents.Meanwhile, the situation that suspension hook throws up the personnel of damaging also happens occasionally, and people's goods is not separated very dangerous.Therefore, according to dangerous not production principle, the safety problem solved in decoupling device operation is very urgent task.
Utility model content
Technical problem to be solved in the utility model provides a kind of simple and reasonable for structure for the above-mentioned state of the art, the automatically-unhooked hooking device of use safety.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of automatically-unhooked hooking device, comprise hook, also comprise the support be connected with hoisting device, described support and hook are rotationally connected, described hook comprises coupler body and counter weight, described counter weight is connected with the end of coupler body, and the weight of described counter weight is greater than the weight of coupler body.
Preferably, described support comprises pipe link, and described pipe link and hook are rotationally connected.
Preferably, described support also comprises pole, and one end of described pipe link is connected with pole, and the other end and the hook of described pipe link are rotationally connected.
Preferably, described pipe link comprises head rod and the second pipe link, and two described head rods are connected with the two ends of pole respectively, and two described second pipe links are connected with the middle part of pole respectively and lay respectively at the both sides of pole.The technical program is provided with four hooks, and what be applicable to have four suspension ring has treated weight, as ton bag; The hooking device of the technical program can be sling a ton bag reposefully.
Preferably, two described second pipe links are about the plane symmetry at pole place; Two described head rods are about the plane orthogonal at two second pipe link places.The pole of the hooking device of the technical program is provided with equably four hooks, during with its hoisting heavy, four hooks homogeneity firmly can be ensured, thus ensure the stationarity of hoisting heavy.
Preferably, the middle part of described pipe link and hook is rotationally connected.
Preferably, described hook and pipe link hinged.
Preferably, described hook is rotationally connected by pin and pipe link.
Compared with prior art, the utility model has the advantage of: this automatically-unhooked hooking device is provided with counter weight on hook, weight because of counter weight is greater than the weight of coupler body, when unloading heavy, counter weight is rotated by the relative pipe link of Gravitative Loads, accordingly, coupler body upwards rotates, now link up with inversion, lifting thing departs from hook, thus achieves automatically-unhooked.
This hooking device is simple and reasonable for structure, and lifting is convenient, and can realize automatically-unhooked, and in addition, this hooking device is safe and reliable.

Fig. 1 is the structural representation of the utility model embodiment hook;
Structural representation when Fig. 2 is the suspension ring of the utility model embodiment hooking device hook ton bag;
Fig. 3 is the structural representation of the utility model embodiment hooking device when playing gross ton bag;
Fig. 4 is the structural representation that the utility model embodiment hooking device unloads when weighing.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
The automatically-unhooked hooking device of the present embodiment, as shown in Figure 1, the support comprising hook 1 and be connected with hoisting device.Wherein, hook 1 comprises coupler body 11 and counter weight 12, and counter weight 12 is connected with the end of coupler body 11, and the weight of counter weight 12 is greater than the weight of coupler body 11; Support comprises pole 4 and pipe link, and one end of pipe link is connected with pole 4, is rotationally connected in the middle part of the other end of pipe link and hook 1.
The mode that is rotationally connected of the present embodiment for hinged, can be specially: be rotationally connected by pin 5 in the middle part of the end of pipe link and hook 1, hook 1 can do 360 ° of rotations around pin 5.
Pipe link comprises two head rods 2 and two second pipe links, 3, two head rods 2 are connected with the two ends of pole 4 respectively, and two second pipe links 3 are connected with the middle part of pole 4 respectively and lay respectively at the both sides of pole 4.Angle between head rod 2, second pipe link 3 and pole 4 is respectively obtuse angle.
Exert a force harmonious in order to ensure four on support hook 1, two second pipe links 3 are about the plane symmetry at pole 4 place; Two head rods 2 are about the plane orthogonal at two second pipe link 3 places.
The pole 4 of i.e. the present embodiment support is symmetrically distributed with four pipe links and hook 1, for four suspension ring of ton bag of slinging, the middle part of pole 4 is provided with the connecting portion 6 be connected with weight-lifting equipment.
With the automatically-unhooked hooking device hoisting heavy of the present embodiment, such as, during ton bag, manually the hook 1 of four on support is hooked four suspension ring of ton bag, when hooking the suspension ring of ton bag, link up with 1 dextrorotation and go to the position shown in Fig. 2; Under the effect of hoisting device, when this automatically-unhooked hooking device plays gross ton bag, suspension ring rotate clockwise the position shown in Fig. 2 because the weight of ton bag hauls hook 1.Haul hook 1 by suspension ring, the friction force between suspension ring and hook 1 makes movable hook not overturn, and remains on the position of Fig. 3, thus a ton bag of slinging.
When unloading ton bag, support falls, and hook 1 does not bear the weight of ton bag, does not have friction force between hook 1 and suspension ring, and hook 1 up time under the effect of counter weight 12 rotates the position to Fig. 4, and ton bag suspension ring depart from hook 1, thus achieve automatically-unhooked.
