Therefore, when lifting an object, a crane is required to connect the double hook hanger and move the double hook hanger to a position close to the object to be lifted, an operator approaches the double hook hanger, manually moves the double hook hanger to the horizontal position, inserts the double hook hanger into the hollow part of the coil-like object, and then the crane lifts the double hook hanger together with the object to be lifted and moves the double hook hanger to a required position.
However, the double-hook lifting appliance and the articles to be lifted have large mass, so that labor is consumed to a large extent by using the above method, and in the case that the articles to be lifted are stacked in multiple layers, an operator needs to climb on a lower layer to be lifted to contact and move the double-hook lifting appliance, which also causes great potential safety hazards.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: to the problem that above-mentioned existence, provide one kind and do not need operating personnel manual removal double hook hoist, can be at idle load and the balanced hoist of double hook of automatically regulated focus under the state of hanging the thing.
The utility model adopts the technical scheme as follows:
the utility model provides a balanced hoist of double hook, includes jib, the lifting hook that is parallel to each other, still includes lifting rope, the stretch cord of being connected with the jib, and the one end of lifting rope, stretch cord is close to the both ends of jib respectively, and the other end interconnect of lifting rope and stretch cord, and balanced hoist of double hook is hoisted for the hoisting point by the tie point of lifting rope and stretch cord.
Preferably, the double-hook balance lifting appliance further comprises an extension frame arranged along the extension line of the lifting rod, and the elastic rope is connected with the extension frame.
Preferably, the extension frame is further connected with an auxiliary rope.
Preferably, the tension of the bungee cord is one-half the weight of the hook.
Preferably, the bungee cord has the same original length as the length of the lifting cord.
Preferably, a connecting frame is connected between the hanging rod and the lifting hook, and the connecting frame is arranged close to the elastic rope.
Preferably, the extension bracket is fixed to the connection bracket.
Preferably, the lifting hook is provided with an anti-slip edge.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: in the no-load state, the device takes the connecting point of the lifting rope and the elastic rope as a lifting point, the lifting point is the gravity center of the whole device, the suspender, the lifting rope and the elastic rope form a triangular stable state, and the suspender and the lifting hook are relatively horizontal, so that the lifting hook can be conveniently inserted into an object to be lifted subsequently; under the state of lifting the object, the elastic rope extends, and the gravity center of the device moves to the connecting point of the lifting rope and the lifting rod, so that the device and the object to be lifted can be smoothly lifted. The operator does not need to manually move the device in the process of hanging the objects, so that the consumption of manpower is relatively reduced, and potential safety hazards are relatively avoided under the condition that the objects to be hung are stacked in multiple layers.
Drawings
Fig. 1 is a schematic structural diagram of a double hook balancing sling.
The labels in the figure are: the lifting device comprises a lifting rod 1, a lifting hook 2, a lifting rope 3, an elastic rope 4, an extension frame 5, an auxiliary rope 6, a connecting frame 7 and an anti-skid edge 8.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a double-hook balance hanger includes a suspension rod 1 and two suspension hooks 2 parallel to each other, and further includes a lifting rope 3 and a stretch rope 4 connected to the suspension rod 1, the lifting rope 3 is a chain, the stretch rope 4 is a spring, one end of the lifting rope 3 and one end of the stretch rope 4 are respectively close to two ends of the suspension rod 1, the other end of the lifting rope 3 and the other end of the stretch rope 4 are connected to each other, and the double-hook balance hanger is lifted by using a connection point of the lifting rope 3 and the stretch rope 4 as a lifting point.
Furthermore, the double-hook balance hanger also comprises an extension frame 5 arranged along the extension line of the hanger rod 1, and one end of the elastic rope 4 is tied to the end part of the extension frame 5.
Furthermore, an auxiliary rope 6 is tied on the extension frame 5, one end of the auxiliary rope 6 is close to one end of the elastic rope 4, the other end of the auxiliary rope 6 is held by an operator, and when the double-hook balance hanger breaks the balance state under external force, the operator uses the auxiliary rope 6 to adjust the double-hook balance hanger to enable the double-hook balance hanger to reach the balance state as soon as possible.
Furthermore, the tension of the elastic rope 4 is half of the weight of the lifting hook 2, so that when the double-hook balance lifting appliance lifts an object to be lifted, the elastic rope 4 can be stretched to enable the gravity center of the double-hook balance lifting appliance to move to the connecting point of the lifting rope 3 and the lifting rod 1.
