Abstract
The invention relates to a controllable self-modulation hook which comprises a fixed base, a foot bracket, a push pole and a support block. The use process of the invention is as follows: pulling up the push pole to move the support block towards the fixed base direction when needing a lifting inner bore to bear an object. The trapezoidal gradient is larger than the small inclined plane gradient of the foot bracket; thereby the foot bracket is opened by the outer wall acting force of the support block and the foot bracket can be fixed on the inner wall step of the object; a hook on the foot bracket can be arranged at a nozzle of the object, and then the hook of a crane is hooked on a ring, then the object can be lifted and moved; if the push pole is pushed reversely, the support block is pushed back to the original position. As the foot bracket and the fixed base are hinged, and the hinged part is provided with a spring, the foot bracket is reset to the original state, as a result the controllable self-modulation hook can be taken down from the object. The controllable self-modulation hook of the invention features simple structure, convenient and safe operation and brings great convenience for the object transportation.
Description
Technical field
The present invention relates to a kind of lifting tool, relate in particular to a kind of controllable self-modulation hook.
Background technology
In workshop or similar site, often run into that need to move or carry some volume ratio big or weight is heavier, and smooth surface does not have acting point, but endoporus has the situation of the object of step, when this class object outside can not be lifted by crane under the situation of support, taking a lot of time moves, and very dangerous.In that object is heavier can not carry out a dead lift the time, need the crane handling, but the front end of crane is a hook, therefore need instrument one end can connect object and fixing with it, the other end with can be connected with the hook on the crane.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of convenience the hook bonded assembly controllable self-modulation hook on object and the crane.
For achieving the above object, the present invention adopts a kind of controllable self-modulation hook, comprise permanent seat, foot support, push rod, bracer, offer through hole in the middle of the permanent seat vertically, outer edge at permanent seat is radially distributed with 3 mobilizable foot supports along it, the foot support shape is the L type, hinged and the outward-dipping setting of one end and permanent seat, the other end forms the grab of outer folding, on the medial surface of foot support, form 2 sections inclined-planes that gradient is different, promptly the little inclined-plane gradient of close permanent seat one side is less than the big inclined-plane gradient near grab one side, push rod passes the through hole of permanent seat versatilely, push rod and through hole constitute free-running fit, the other end of relative foot support forms suspension ring on the push rod, the other end of push rod is connected with bracer, bracer places the permanent seat below, it is the position between the foot support, the cross section of bracer is trapezoidal, trapezoidal gradient is less than or equal to the gradient on the big inclined-plane of foot support, trapezoidal gradient is greater than the gradient on the little inclined-plane of foot support, trapezoidal and foot support trapezoidal with foot support on the slope difference on little inclined-plane equal the open angle of foot support, stretch by push rod, realize moving up and down of bracer, constitute opening or closing up of foot support.
The assembly and disassembly of push rod and bracer for convenience, the present invention further are set to relative bracer one end formation outside thread on the push rod, and push rod is threaded with bracer.
The self-return of foot support for convenience, the present invention is set to further that corresponding hinge-point with foot support is provided with spring on the permanent seat.
Use of the present invention: when needs lifting object, to draw on the push rod, bracer is moved toward the permanent seat direction, because trapezoidal gradient is greater than the gradient on the little inclined-plane of foot support, therefore the application force of the outer wall of bracer is opened foot support, foot support just can be fixed on the inwall step of object, and the grab on it can be fastened on the tube port position of object, the hook of crane is hooked that suspension ring can be sling object again and moves; Anti-push rod, bracer are then got back to the home position, owing to be hinged between foot support and the permanent seat, and being provided with spring in the articulated section, foot support is returned to initial condition, controllable self-modulation hook can be taken off from object.Controllable self-modulation hook of the present invention is simple in structure, and is easy to operate, brings very big convenience for the carrying of object, eliminates safe hidden trouble simultaneously.Controllable self-modulation hook of the present invention can be applicable to workshop or similar site, and it is big or weight is heavier to be used to solve some volume ratio, and smooth surface does not have acting point, but endoporus has the carrying or the mobile operating problem of the object of step, cooperates crane to use.

Fig. 3 is an embodiment of the invention running condition front view.
Fig. 4 is that the embodiment of the invention and cylindrical shell are used view.
The specific embodiment
As Fig. 1,2, shown in 3, specific embodiments of the invention are a kind of controllable self-modulation hooks, comprise permanent seat 1, foot support 2, push rod 3, bracer 4, the spline of the similar 3 limit shapes of the cross-sectional plane of permanent seat 1, offer through hole in the middle of the permanent seat 1 vertically, outer edge at permanent seat 1 is radially distributed with 3 foot supports 2 that are articulated and connected with permanent seat along it, corresponding hinge-point with foot support 2 is provided with spring on the permanent seat 1, foot support 2 shapes are the L type, its upper end and permanent seat 1 hinged and outward-dipping setting, the lower end forms the grab 21 of outer folding, on the medial surface of foot support 2, form 2 sections inclined-planes that gradient is different, promptly little inclined-plane 22 gradients of close permanent seat 1 one sides are less than big inclined-plane 23 gradients near grab 21 1 sides, push rod 3 passes the through hole of permanent seat 1 versatilely, and push rod 3 constitutes free-running fit with through hole, and the other end of relative foot support 2 forms suspension ring 31 on the push rod 3, the other end of push rod 3 forms outside thread 32, and push rod 3 is threaded with bracer 4.Bracer 4 places permanent seat 1 below, it is the position between the foot support 2, the cross section of bracer 4 is trapezoidal, trapezoidal gradient is less than or equal to the gradient on the big inclined-plane 23 of foot support 2, trapezoidal gradient is greater than the gradient on the little inclined-plane 22 of foot support 2, and the slope difference on the little inclined-plane 22 on trapezoidal and the foot support 2 equals the open angle of foot support 2, stretches by push rod 3, realize moving up and down of bracer 4, constitute opening or closing up of foot support 2.
As shown in Figure 4, the use of controllable self-modulation hook of the present invention: when needs lifting object, to draw on the push rod 3, bracer 4 is moved toward permanent seat 1 direction, because trapezoidal gradient is greater than the gradient on the little inclined-plane 22 of foot support 2, so the application force of the outer wall of bracer 4 opens foot support 2, and foot support 2 just can be fixed on the inwall step of object 5, grab 21 on it can be fastened on nozzle 51 places of object 5, the hook of crane is hooked that suspension ring 31 can be sling object 5 again and moves; Anti-push rod 3,4 of bracers are got back to the home position, owing to be hinged between foot support 2 and the permanent seat 1, and are provided with spring in the articulated section, and foot support is returned to initial condition, controllable self-modulation hook can be taken off from object 5, has not only made things convenient for but also safety.
