Definitions
- the invention relates to a broker according to the preamble of claim 1.
- brokers which represents a mast with guide rail along which slides a slide, which is suitable for holding tools such as drills, vibrators, quick hammers, diesel bears, presses and the like. is trained.
- the broker is usually attached to a hydraulic excavator. Its task is to guide the tools and to create contact and tensile forces.
- the brokers are either designed to perform a task, or, as with the universal leader, designed for working with various equipment. In the Universalmäklem outweigh embodiments in which the tools are conventionally mounted with screws and bolts firmly on the slide of the leader. An exchange of the implement therefore takes in Switzerland tardkemper of this kind therefore usually several hours.
- the aim is to optimize the mechanical pickup devices. For example, at the DE 43 12 368 A1 a time saving when changing equipment achieved in that the mechanical connection between the implement and lifting is made with a hydraulic lock.
- the tools are designed as exchange devices. They are mounted on a guide slide, which slides in the guide rail of the leader. When replacing the implement, the guide carriage is moved out together with the implement from the guide rail and instead used a complete unit of guide carriage and provided implement again. For this exchange process only a small amount of time is required.
- the invention has set itself the task of specifying a changing device, which significantly shortens the entire change process when replacing equipment, allows leakage-free switching, and also eliminates errors due to human error.
- the guide carriage carries the implement while the base carriage provides the supply lines for the implement.
- the base carriage is equipped with a plate with coupling elements.
- This plate cooperates with a coupling block, which is mounted on the guide carriage and equipped with counter-receptacles for the dome elements.
- both carriages are connected to one another with a generally hydraulically operating locking device. In this position, the coupling elements of the plate engage in the Countermounts in the coupling block and thus establish the hydraulic connection between the base carriage and implement.
- the broker sets the implement on a stable surface. Subsequently, leading to the implement hydraulic lines are depressurized and released the locking devices between the base and guide carriage. As a result, the mechanical connection between the base and guide carriage is canceled. Subsequently, the base carriage is raised while the guide carriage remains on the base with the implement. During this process, all hydraulic feeds leading to the implement are disconnected from the implement. The separation takes place in that the coupling elements of the plate attached to the base carriage are moved out of the corresponding counter-receptacles of the coupling block attached to the guide carriage. Thus, the disassembly of the implement is almost completed. It remains only the unthreading of the implement from the guide rail of the leader. This process is performed by raising the leader.
- Makers must be set only for very short periods out of service. Since downtime for high-tech equipment, such as brokers, are very expensive, can be saved considerable costs with the present invention.
- the coupling elements arranged on the plate in the form of plugs the counter-receptacles on the coupling block in the form of sleeves formed are.
- the plug of the base carriage attached to the plate are also shielded by the locking device also attached to the base carriage and therefore protected from mechanical damage.
- Plate and block generally have a plurality of hydraulically actuable coupling elements or counter-recordings. Since different tools sometimes require a different number of hydraulic lines, the number of coupling elements and the counter-receptacles is dimensioned so that when using the various tools each required hydraulic lines are provided. In an advantageous embodiment, therefore, corresponds to the number of coupling elements and the counter-receptacles equal to the maximum number of hydraulic lines occurring in the different equipment.
- the base and guide carriages are joined together and connected to the locking device with each other.
- the joining process designed as a plug coupling elements of the plate must be introduced into the counter-receptacles formed as sleeves on the coupling block.
- the plate is floating and has elements for aligning the plate in the plane of the plate, which cooperate with the corresponding counter-elements in the coupling block. These elements, in cooperation with the floating support of the plate, ensure that the plate and coupling block are precisely aligned before the plugs engage the respective sleeves.
- the coupling block on the side of the counter receptacles is equipped with a leakage oil channel in a further development of the changing device. This channel is used to receive and forward the leakage oil to an oil sump.
- the implement In a trained according to the present invention leader the hydraulic connections between the parent carriage and implement are made automatically.
- the different operation of the individual tools requires the setting of different operating conditions, such as adjustment of oil quantity, flow direction and operating pressure.
- the implement is equipped with a memory unit in which information about the implement, preferably hydraulic and electrical operating data stored. It is advantageous if the memory unit is battery-free, preferably using an NMOS-EPROM or FRAM operated.
- the storage unit operates wirelessly, preferably by means of electromagnetic induction, together with an electronic data reader / writer provided on the guide or base carriage.
- the reading device forwards data read from the memory unit as signals to the machine control of the leader and / or signals from the machine control as data to the memory unit.
- the communication between reading and writing device and the machine control is usually via a serial interface.
- Data read from the storage unit relates to the operating data of the implement. Based on this information, the hydraulic lines to the valves on the plate attached to the base carriage are released and hydraulically acted upon.
- Data passed to the memory unit may include, for example, the hours of operation or times of particular operating conditions, such as periods of operation. As overloads, hold on. Overall, this data can be detected, which are necessary for maintenance, maintenance or repair of the implement.
- the memory unit and the read / write unit allow automatic recognition of the type of implement and all data relevant to the operation of this device. Operating errors due to manual intervention are therefore excluded.
- the data stored in the memory unit may also be of interest outside the operating hours of the author. Therefore, in the present invention, a hand-held terminal is provided which has the characteristics of the reading device and allows to query the data from the memory unit.
- a working device usually has electrical supply lines in addition to the hydraulic supply lines. Feeders of electrical type or data lines are also required for the reading unit. These cables are therefore equipped with basic connections and work equipment with plug connections.
- the connections between the base carriage and the inside of the locking device are formed. Through this training, it is achieved that in the same operation with the closing or opening of the locking device and the electrical connections are closed or opened.
- this arrangement provides for the connectors also some protection both against mechanical damage as well as against oil and moisture in the periods in which the base and guide carriages are separated.
- FIG. 1a is reproduced attached to the base carriage plate.
- the illustration shows the guide carriage facing side with the dome elements designed as a plug (1).
- the plugs have two different-sized embodiments (1 '), (1 "), which are assigned hydraulic lines with different throughputs
- elements (2) for aligning the plate which are formed as columns. These columns serve as a joining aid in assembling the floating plate and the coupling block.
- FIG. 1b shows the opposite side, ie the side of the plate facing the base carriage.
- the reference numeral (3) indicates the other ends of the plugs, which are designed as connections and are connected to the hydraulic feeders on the base carriage.
- FIG. 2 gives a view of the coupling block again.
- This block is mounted on the guide carriage and points with its upper side (4) to the base carriage.
- the counter-receptacles (5) are reproduced to the coupling plugs of the plate, which are formed in the present embodiment as sleeves.
- holes (6) can be seen, which receive the serving as mounts columns (2) of the plate.
- a leakage oil passage (7) is provided, which feeds the accumulating at each uncoupling leak oil lying under the clutch block, not shown, oil sump.
- On the front side (8) of the coupling block openings (9) are reproduced by channels, which are formed within the coupling block and with the respective sleeves (5) have connection. The hydraulic hoses of the implement are connected to these openings.
