Abstract
The utility model provides a multifunctional hydraulically controlled variable angle jib. The jib is technically characterized in that four hinged points at the front end of a variable angle frame are connected with a lifting lug at the front end of a main arm of an automobile crane; an upper hinge point at the rear end of the variable angle frame is connected with a cylinder body hinged point of a variable angle hydraulic oil cylinder; a hinged point at the lower end of the variable angle frame is connected with a lower hinged point of a jib body; a hinged point at a flexible rod end of the variable angle hydraulic oil cylinder is connected with an upper hinged point of a sequence jib body through a pin shaft, and then the variable angle of the jib is realized through the stretching of the hydraulic oil cylinder; and a bidirectional hydraulic lock is connected with a variable angle hydraulic oil cylinder body through a bolt, and is used for preventing accidents caused by the fact that a pipeline cracks and the hydraulic cylinder extends out in an acceleration manner. The multifunctional hydraulically controlled variable angle jib has the advantages of achieving multiple purposes, and being applicable to not only jib working conditions, but also high-altitude platform operation.
Description
Technical field
The utility model relates to a kind of car hosit, particularly the multi-functional hydraulic control angle of a kind of car hosit auxiliary.
Background technology
Along with expanding economy both at home and abroad, engineering construction project is also more and more, and the frequency that car hosit uses is also more and more.Because specific operation demand, car hosit need could operation under the auxiliary angle operating mode.Now adopt the armstrong's patent formula to regulate the auxiliary angle, it is in control process, and work capacity is big, and regulating error is big, and efficient is lower.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and the multi-functional hydraulic control angle of a kind of car hosit auxiliary is provided.Can be under specific operation, automobile crane subsidiary arm is realized automatic angle, convenient, fast and accurately is implemented in operation under the specific operation.Simultaneously can install high-altitude operation platform additional in the auxiliary end, can in 0 °～45 ° scopes of principal arm, carry out aloft work.
The purpose of this utility model is achieved in that and comprises angle variable frame, hydraulic ram, hydraulic lock, three position four-way directional control valve, auxiliary body.It is characterized in that four hinges of the front end of angle variable frame are connected with car hosit principal arm front end hanger by bearing pin, hinge is connected with angle hydraulic ram cylinder body hinge by bearing pin on the angle variable frame rear end, and the lower end hinge is connected with hinge under the auxiliary body.The flexible rod end hinge of angle hydraulic ram is connected with hinge on the order auxiliary body by bearing pin, then by the flexible auxiliary angle of realizing of hydraulic ram.Bidirectional hydraulic lock is connected with angle hydraulic ram cylinder body by bolt, and effect is to prevent that pipe breakage from causing hydraulic actuating cylinder to accelerate to stretch out, and causes the accident.Car hosit is when the specific operation operation, at first adjust principal arm angle and principal arm length by amplitude oil cylinder and telescopic oil cylinder, pull auxiliary angle pull bar then and make the three-position four-way valve commutation, the angle hydraulic ram is flexible to make auxiliary body angle reach the operating mode of wanting, hoisting heavy fulfils assignment.When carrying out aloft work, along with the change of principal arm change angle, regulate auxiliary angle hydraulic actuating cylinder accordingly, the work bucket of making remains horizontality, installs bidirectional hydraulic lock on the hydraulic actuating cylinder additional, prevents that pipe breakage from causing the hydraulic actuating cylinder retraction, and platform inclination has an accident.
The utility model is compared with existing product, and main advantage is, can realize a tractor serves several purposes, namely can be used as the auxiliary operating mode and carries out the High Altitude Platform operation again.

Fig. 1 is the utility model constructional drawing
Fig. 2 is the birds-eye view of Fig. 1
Fig. 3 is hydraulic schematic diagram of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing present embodiment is described further
By Fig. 1-2 as can be known, four hinges of the front end of angle variable frame 1 are connected with car hosit principal arm front end hanger by bearing pin, and hinge is connected with the cylinder body hinge of angle hydraulic ram 3 by bearing pin on the angle variable frame rear end, and 4 times hinges of lower end hinge and auxiliary body are connected.The flexible rod end hinge of angle hydraulic ram is connected with hinge on the auxiliary body by bearing pin, by the flexible auxiliary angle of realizing of hydraulic ram.Bidirectional hydraulic lock 2 is connected with angle hydraulic ram cylinder body by bolt, and effect is to prevent that pipe breakage from causing hydraulic actuating cylinder to accelerate to stretch out, and causes the accident.
As shown in Figure 3, from swivel coupling, in the high pressure fuel pipe of the valve of getting on the bus, tell one road to 3-position 4-way hand change over valve P mouth oil inlet with T-pipe joint, three position four-way directional control valve mouth A, B are connected with the bidirectional hydraulic lock hydraulic fluid port respectively, flexible by hand change over valve regulator solution compressing cylinder, change-over valve T mouth connects in the working connection oil return.
