The present invention relates to a mechanism providing safe, fast and automatic opening and closing of jib located on main boom without need for manual activation, which is used to provide enhancement of effect range of telescopic boom cranes.
Background of the Invention
In current applications opening jib mechanism requires great quantity of man effort and manual workmanship. Production process and workmanship costs are highly affected by manual performance of this process. Therefore, more time and workmanship is needed to be included in operation of jib mechanism.
Multi-personnel are needed in current applications as the said jib mechanism is operated by manual intervention. Employing more than one person for a work affects cost, production and processes considerably.
When the said operation is performed manually, the pins used for opening and fixing the jib mechanism are less safe when compared to the systems opened and fixed by automation systems.
Also when workmanship is conducted manually, the joining operation may not be performed in a practical way.
When the subject matter was searched in literature, a European patent numberedEP2842903 was found. The said application discloses a device that being part of jib and this jib can extend and retract. In the said application, jib is not fitted when required but works as integrated to the system all times. Non-modular jib causes problems when working in narrow area.
Because of the above mentioned reasons, a system providing safe and quick fitting of the jib mechanism used for ensuring enhancement of telescopic boom cranes' field of effects is needed. Description of the Invention
From the current related art, the purpose of the invention is to provide safe, quick and automatic opening and closing of the jib mechanism to the system used for providing enhancement of effect range of telescopic boom cranes.
Another purpose of the invention is to activate the jib mechanism by automatic system without need for manual intervention.
A further purpose of the invention is to minimize the production, process and personnel costs by means of automatic start of jib mechanism disclosed hereunder.
Another purpose of the invention is to provide an embodiment wherein the jib mechanism disclosed hereunder continue to perform even in case of electric failures. A further purpose of the invention is to eliminate the work accidents thanks to automatic opening and closing motion of jib mechanism. Thus an embodiment providing high safety in terms of occupational safety is disclosed.
Another purpose of the invention is to convert performance of a work performed by three persons manually into a performance by one person by remote control.
A further purpose of the invention is to minimize the work force by unit time and work processes into minimum levels. Thus, production process and workmanship costs are minimized.

It consists of a rotating piston (91 ) and a second rotating piston (92) giving the first rotation movement to the said jib boom (100) mechanism, a rotating piston (91 ) giving second rotation movement to the said jib boom (100) and located in the same level as the main boom piston (90) and a second rotating piston (92) connected in such a manner to give rotation movement to the said rotation piston (91 ) by means of at least a moving joint (93).
It consists of a joint (93) located between the said rotating piston (91 ) and second rotating piston (92) and giving an angular motion at an angle of 0Q to 180° to the said rotating piston (91 ) and the second rotating piston (92). It contains a locking mechanism (10) ensuring that the jib opens at 180° and fixing in the same alignment by means of the said joint (93). The said locking mechanism (10) consists of lock pistons (1 1 ) moving in vertical axis (Z) and lock pins (12) performing locking by means of vertical motion in z-axis of the said lock pistons (1 1 ). Also it contains dust blowers (14) positioned in vertical axis (Z) of lock pistons (1 1 ) by means of flap for locking (15). Figure 6 shows load grasping hydraulic system (1 1 1 ) of the lock pistons (1 1 ).
90 In addition, there are several lock bearings (13) provided on main boom (A) where lock pins (12) are located on vertical axis (Z) upon driving, and flap for rotation center (94) on front surface of main boom (A) where the said second rotating piston (92) is connected. It contains at least a sleeve (95) provided on moving jib boom (100) fixing the second rotating piston (92) and rotating piston (91 ) in the same direction.
On the other hand, it consists of safety valve (20) preventing oil at pressure higher than operating range of the second rotating piston (92), a pressure valve (30) providing control of pressure of oil flowing to rotating pistons (91 ), direction valve (50) activating rotating piston (91 ) single load check valve (60) providing operation of rotating piston (91 ) in a safe manner. Moreover, it consists of speed control valve (70) providing regulation of pressure of oil transmitted to the said rotating piston (91 ), electrical poppet (80) providing operation of single load check valve (60).
After jib boom (100) opens and locks automatically, operator dismantles the electric connection socket manually. Then machine becomes ready for use. During use, jib boom (100) does not have electricity, it has been designed like that because of preventing any potential failures. In order to prevent hydraulic failure, it has locks to prevent return of oil after the system is full. After completion of the work, the machine is retracted and operator plugs in socket and jib boom (100) closes and locks. Opening-closing system of jib boom (100) is fully free of any electrical and hydraulic failures and is 100 % safe.
The operating of the jib boom (100) mechanism is as follows: After giving electric to direction valve (50), single load check valve (60) located on the main boom (A) is activated. Single load check valve (60) provides safety against hose bursting. Operation of single load check valve (60), main boom piston (90) lifting jib boom (100) operates. Upon this operation, jib boom (100) moves from 0 degree up to 40 degrees. When direction valve (50) of the jib boom (100) is energized, pressure valve (30) starts piston movement. The driven pistons direct the cylinder driving valve (40). Thereafter, the speed control valve (70) is driven and electrical poppet (80) is driven and thus hydraulic valve provides oil. Rotating piston (91 ) is connected to expellant and puller from electrical poppet (80). Upon start of rotating piston (91 ) motion, second rotating piston (92) opens and closes the jib boom (100) on rotating axis (x) at 90 degrees. Also cylinder driving valve (40) shifts to single load check valve (60) and provides high safety against hydraulic hose bursting. From single load check valve (60) to safety valve (20), locking of lock mechanism (10) at vertical axis (z) is provided. Lock mechanism (10) preferably consists of two lock pistons (1 1 ) and the lock pins (12) are pushed and housed in lock bearing (13) by means of vertical
motion given via hydraulic cylinder on z-axis to the said lock pistons (1 1 ). Thus jib boom (100) is fixed to the main boom (A) (see Figure 4).
It consists of joint (93) having two different x1 , x2 rotating axis, independent of each other and housed to the said main boom (A) from single point x-1 axis to second rotating piston (92) and in a manner making rotating movement on the same x2-axis of the rotating piston (91 ) by the said second rotating piston (92).
