Abstract

The utility model discloses a pivot shaft device for a crane, since a hinge seat of a hinge device is divided into two half bodies along a symmetrical shaft line, a gap for the two half bodies to relatively rotate is arranged between the two half bodies, the half bodies of the two hinge seats are respectively fixed on the corresponding positions of a crane vehicle body and a crane stillage truck frame, a jointed shaft can be firstly mounted on either of the half bodies of the hinge seats in assembly, and the other half body of the hinge seats is finally mounted on the jointed shaft, and the installation is convenient and labor-saving, the relative rotation gap of the two half bodies guarantees the rotation angle between the crane vehicle body and the crane stillage truck frame, load of the crane is led to be evenly distributed on each wheel, when being disassembled, the two hinge seats are separated by a jack, and then, the jointed shaft is taken out, and finally, the crane stillage truck frame is moved, the disassembly is simple, and the maintenance is convenient. The pivot shaft has low installation precision requirement, simple and convenient adjustment, labor-saving and time-saving disassembly and assembly, and improves the production and operation efficiency of enterprises.

Description

Hoisting crane hinge device

Technical field

The utility model relates to a kind of hinge device, relates in particular to the hinge device that a kind of hoisting crane is used.

Background technology

Be by the articulated mounting bonded assembly between the car body of hoisting crane and the bogie frame, when common articulated mounting is installed, need bore two holes separately on bearing and bogie frame respectively, the two assembling needs four articulation hole coaxial lines, accuracy requirement height, installation is wasted time and energy, difficulty is bigger, and when safeguarding dismounting, and the side direction end carriage is striden the outside and thrown axle in needing stride from end carriage, the no point of application is wasted time and energy and dangerous.

As the present inventor, be devoted for years to production in hoisting crane, have rich practice experience.Through the concentrating on studies of contriver, creatively work out articulated mounting between a kind of car body that is used for hoisting crane and the bogie frame, this articulated mounting convenient for installation and maintenance, laborsaving.

The utility model content

Technical problem to be solved in the utility model provides a kind of easy installation and hoisting crane easy to maintenance hinge device.

For solving the problems of the technologies described above, the technical solution of the utility model is: hoisting crane hinge device, comprise, and jointed shaft and hinged seat, described jointed shaft rotates and is installed in the described hinged seat; Described hinged seat is split into two halfbodies along diad, has between described two halfbodies to allow both gaps in relative rotation.

As a kind of improvement, described hoisting crane also comprises two end caps with the hinge device, and described two end caps are individually fixed on the two ends of described jointed shaft and the end face that retaining leans against described hinged seat.

As further improvement, be provided with hermetically-sealed construction between the corresponding end face of described end cap and hinged seat.

After having adopted technique scheme, the beneficial effects of the utility model are: because the hinged seat of this articulated mounting is split into two halfbodies along diad, have between described two halfbodies and allow both gaps in relative rotation, so, two hinged seat halfbodies are separately fixed on the relevant position of hoisting crane car body and hoisting crane bogie frame, during assembling, can earlier jointed shaft be installed in the halfbody of hinged seat, at last another hinged seat halfbody is installed on the jointed shaft, easy for installation and laborsaving, and the gap that relatively rotates between two halfbodies has guaranteed rotational angle between hoisting crane bogie frame and the hoisting crane car body load of hoisting crane to be evenly distributed on each wheel of hoisting crane; During dismounting, with jack with two hinged seats separately, take out jointed shaft again, last jenny bogie frame is dismantled simple and directly, maintains easily.The end cap that is provided with at the jointed shaft two ends can block jointed shaft and not come off in hinged seat, uses reliable.It is low that the utility model setting accuracy requires, and adjusts simple and conveniently, and dismounting is laborsaving to save time, and has improved enterprises production efficiency.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is that the A of Fig. 1 is to cutaway view;

Fig. 3 is that the utility model embodiment is installed in the structural representation on the hoisting crane.

In the accompanying drawing: 1. go up hinged seat; 2. bolt; 3. end cap; 4. descend hinged seat; 5. jointed shaft; 6. hoisting crane car body; 7. hoisting crane bogie frame; 8. groove; 9. protruding stupefied; 10. oilway.

The specific embodiment

Hoisting crane hinge device, as depicted in figs. 1 and 2, comprise jointed shaft 5 and hinged seat, described jointed shaft 5 rotates and is installed in the described hinged seat, described hinged seat is split into hinged seat 1 and following hinged seat 4 along diad, has between described upward hinged seat 1 and the following hinged seat 4 to allow both gaps in relative rotation.Described hoisting crane also comprises two disc end caps 3 with the hinge device, and two ends and retaining that described two end caps 3 are individually fixed in described jointed shaft 5 lean against on the end face of described upward hinged seat 1 and following hinged seat 4.Be respectively equipped with groove 8 on the end face of hinged seat 1 and following hinged seat 4 on described, and be provided with protruding stupefiedly 9 with described groove 8 corresponding positions on described end cap 3, described protruding stupefied 9 can insert in the described groove 8.Be provided with oilway 10 on the inwall of hinged seat 1 and following hinged seat 4 on described.

Principle of work of the present utility model: as shown in Figure 3, the described hinged seat 1 of going up is fixed on hoisting crane car body 6 bottoms, with described down hinged seat 4 be fixed on described hoisting crane bogie frame 7 tops and with the last hinged seat 1 corresponding position of described hoisting crane car body 6, during installation, earlier jointed shaft 5 is installed in down 4 li of hinged seats, will goes up hinged seat 1 then and be installed in down hinged seat 4 tops, by bolt 2 that end cap 3 is fixing with jointed shaft 5 at last, setting accuracy requires low, adjusts simple and convenient; During demolition and maintenance, only need end cap 3 is taken off, with jack with upper and lower hinged seat separately, take out jointed shaft 5, the jenny bogie frame 7 again, and " one gets two tops three moves " three steps can be finished dismounting and be safeguarded very rapid and simple convenience.

It is simple that the utility model is made assembly technology, convenient for installation and maintenance quick, improved enterprises production efficiency.
