The hook fixing device for the folding-arm lorry-mounted crane comprises a telescopic arm and a pulley stand, wherein the telescopic arm of the crane is connected with one end of a connecting block, and the other end of the connecting block is connected with the pulley stand; a steel cable is twined on the pulley stand, and one end of the steel cable is connected with a heavy punch; the heavy punch is connected with the hook through a shackle, and the other end of the steel cable is twined on a hoisting mechanism; a plane which can be mutually fitted with the heavy punch is arranged on the peripheral surface of the pulley stand.
Description
Technical field
A kind of folding-jib lorry-mounted crane of the utility model lifting hook fixing device, belongs to technical field of engineering machinery.
Background technology
Lorry-mounted crane is divided into folding-jib lorry-mounted crane and the large class of straight arm type lorry-mounted crane two substantially, and folding-jib lorry-mounted crane is little in retracted state lower volume, it is little to take up room, but operation not as straight arm type lorry-mounted crane convenient; Straight arm type lorry-mounted crane band elevator, after only arm amplitude need being adjusted, utilizes elevator just can realize crane lifting service when lifting weight, but retracted state lower volume large, take up room large; For the advantage of comprehensive this two classes lorry-mounted crane, be born and a kind ofly on folding-jib lorry-mounted crane, installed hoisting mechanism additional, make it possess retracted state lower volume little, under mode of operation, operate feature easily, liked by user.
Yet, adopt the hoisting crane of said structure to produce suspension hook fixation problem, on straight arm type truck with loading crane, suspension hook is generally fixed on its special fixing device, if add elevator on folding-jib lorry-mounted crane, corresponding suspension hook is fixed, and normally at boom assembly weldering lifting hook fixing device, is fixed, more loaded down with trivial details like this, be difficult to realize the Fast Installation of suspension hook and fix.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is to provide a kind of easy to use, and realizes the fixing folding-jib lorry-mounted crane lifting hook fixing device of Fast Installation of suspension hook.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of folding-jib lorry-mounted crane lifting hook fixing device, comprise telescopic boom and pulley yoke, the telescopic boom of described hoisting crane is connected to one end of contiguous block, the other end of described contiguous block is connected with pulley yoke, on described pulley yoke, is wound with wirerope, and one end of described wirerope is connected with weight, described weight is connected with suspension hook by shackle, and the other end of described wirerope is wrapped on hoisting mechanism; The outer surface of described pulley yoke is provided with plane that can be bonded to each other with weight.
Between the telescopic boom and contiguous block of described hoisting crane, between described contiguous block and pulley yoke and between described wirerope and weight, all by quick change bearing pin, be connected.
The utility model compared with prior art, has following beneficial effect.
The utility model is simple in structure, and by install pulley yoke additional on telescopic boom, suspension hook is connected to one end of the wirerope on the pulley being wrapped in pulley yoke, and the other end of wirerope is wrapped on hoisting mechanism, realizes the convenient of lorry-mounted crane hook and uses; When lorry-mounted crane is not worked, while on the way travelling, by hoisting mechanism, reclaim wirerope, the plane of outer surface and the plane of weight that are arranged on pulley yoke are bonded to each other, realize the fixing of suspension hook, have dwindled the volume under hoisting crane recovery state simultaneously, the utility model is changed without the original structure to folding-jib crane, and mostly adopt quick change bearing pin to connect between each component part of this lifting hook fixing device, dismounting is very convenient, reduce staff's working strength.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of suspension hook in stationary state in the utility model.
In figure: 1 is that telescopic boom, 2 is that contiguous block, 3 is that pulley yoke, 4 is that wirerope, 5 is that weight, 6 is that shackle, 7 is that suspension hook, 8 is hoisting mechanism.
The specific embodiment
Structure of the present utility model as shown in Figure 1, a kind of folding-jib lorry-mounted crane lifting hook fixing device, comprise telescopic boom 1 and pulley yoke 3, the telescopic boom 1 of described hoisting crane is connected to one end of contiguous block 2, the other end of described contiguous block 2 is connected with pulley yoke 3, on described pulley yoke 3, is wound with wirerope 4, and one end of described wirerope 4 is connected with weight 5, described weight 5 is connected with suspension hook 7 by shackle 6, and the other end of described wirerope 4 is wrapped on hoisting mechanism 8;
The outer surface of described pulley yoke 3 is provided with plane that can be bonded to each other with weight 5.
Between the telescopic boom 1 and contiguous block 2 of described hoisting crane, between described contiguous block 2 and pulley yoke 3 and between described wirerope 4 and weight 5, all by quick change bearing pin, be connected.
The utility model is simple in structure, and by install pulley yoke additional on telescopic boom, suspension hook is connected to one end of the wirerope on the pulley being wrapped in pulley yoke, and the other end of wirerope is wrapped on hoisting mechanism, realizes the convenient of lorry-mounted crane hook and uses; When lorry-mounted crane is not worked, while on the way travelling, by hoisting mechanism, reclaim wirerope, the plane of outer surface and the plane of weight that are arranged on pulley yoke are bonded to each other, realize the fixing of suspension hook, have dwindled the volume under hoisting crane recovery state simultaneously, the utility model is changed without the original structure to folding-jib crane, and mostly adopt quick change bearing pin to connect between each component part of this lifting hook fixing device, dismounting is very convenient, reduce staff's working strength.
The utility model belongs to the technological improvement to folding-jib lorry-mounted crane, hoisting crane after improvement is used more convenient, the volume of recovery state is less, by reference to the accompanying drawings the specific embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in those of ordinary skills' ken, can in the situation that not departing from the utility model aim, to the utility model, make various improvement.
