Definitions
- the invention relates to a method and a device for disassembling / reassembling hammers, hammer axes and / or protective caps of the rotors of hammer crushers, which are used in particular for the comminution of generally metallic old material.
- Hammer breakers essentially consist of a housing with the rotor mounted therein, which consists of several disks or arm crosses which are non-rotatably attached to a shaft and of hammers distributed between them, which are rotatably mounted on hammer axes which are guided eccentrically to the shaft through the disks, whereby the hammer axes at the same time hold the rotor against wear caps.
- the rotor and especially the hammers, protective caps and the hammer axes holding the latter are exposed to different wear situations as a result of the shredding process.
- Devices with a hydraulic drive are used which represent an independent structural unit which can only be used during the maintenance period, but which are not connected to the actual function of the hammer breaker.
- a hammer axis pulling device it is of importance for the hammer crusher when it comes to both replacing the hammers and protective caps themselves and increasing the availability of the hammer crusher.
- the previous hammer axis pulling devices consisted in principle of a drawbar mounted on a chassis that can be moved by hand, attached to it and movable to it, which required a large amount of space and a great deal of effort, so that the necessary maintenance times had an unfavorable effect on the availability of the hammer breaker system.
- the invention has for its object to develop a method and a device which simplifies the disassembly and reassembly of hammers, hammer axes and / or protective caps in hammer breakers in such a way that pull rods are dispensed with and the device can be built compactly, furthermore low manufacturing costs for the Device arise and the sequence of disassembly and reassembly leads to increased availability of the hammer breaker due to short maintenance times.
- the advantages of the invention in their entirety and in solving the problem are that the method with the device on the use of tie rods can dispense with, a small space requirement for the drawing operations can be realized, so that the work platforms, buildings and / or soundproofing walls surrounding the hammer crusher can be built closer to the hammer axis pulling device. Furthermore, the traverse can be moved to the rotor by means of the drive, without time-consuming manual work for moving a chassis. Finally, the compact design guarantees lower manufacturing or investment costs for the installation of a hammer crusher, and the function according to the invention increases the availability of a hammer crusher system.
- FIG. 1 is a schematic representation of the process sequence and the construction of the invention with the functions a) hammer axis pulling device in the ready state, b) establishing the connection between cross member and rotor, c) pulling the hammer axis in 3 strokes,
- Fig. 2 shows the construction principle of the hammer axis pulling device with hydraulic drive in releasable operative connection to the longitudinally cut rotor of the hammer breaker and
- Fig. 3 shows the rotor of FIG. 2 in the front view initially without features of the hammer axis pulling device, wherein the section AA represents the section AA of FIG. 2 and contains the section BB, which is shown as a detail BB. Best way to carry out the invention
- a rotor 1 mounted in a housing of a hammer crusher (not shown) is first explained according to FIGS. 2 and 3.
- the rotor 1 consists of a plurality of disks 1.2 or arm crosses which are attached to a shaft 1.1 in a rotationally fixed manner, and of hammers 1.3 which are arranged between them and which are rotatably mounted on hammer axes 1.5 which are guided eccentrically to the shaft 1.1 through the disks 1.2.
- the hammer axes 1.5 also hold protective caps 1.4, which protect the rotor 1 with its disks 1.2 against wear.
- the hammer axes 1.5 are secured in the axial direction with releasable locking pieces 1.7, which are fastened to the outer disks 1.2.
- recesses such as elongated holes 1.6, are provided in the outer disks 1.2 as a corresponding fastening element for a hammer axis pulling device 2 to be attached for the disassembly and reassembly of the hammers 1.3, hammer axes 1.5 and protective caps described at the outset, which is shown in FIG. 1.
- the hammer axis pulling device 2 consists of a drive unit 2.8 which is connected to a lockable carriage 2.4 which can be moved on an anchored rail frame 2.9 and which has a cross member 2.1 with fastening elements 2.3, such as hammer head screws, which engage and engage in the recesses 1.6 previously described. Both the entire carriage 2.4 to the rotor 1 and the crossmember 2.1 are movable relative to one another.
- a pulling head 2.2 is attached on the one hand to the hammer axis 1.5 after the closure piece 1.7 has been removed, and on the other hand connected to the slide 2.4 in several relative positions to one another.
- the drive unit 2.8 consists of two hydraulic cylinders 2.8.1, 2.8.2, which are attached to the slide 2.4 and whose piston rods 2.8.3, 2.8.4 are connected by means of the cross member 2.1.
- the drive unit 2.8 can also consist of an electric motor (not shown) with a spindle, the spindle being connected to the crossmember 2.1 via a screw.
- the crossbeam 2.1 has, as fastening elements 2.3, said hammer head screws which engage in the corresponding elongated holes or recesses 1.6 of the end plate 1.2 or the element of the rotor 1, engage behind the end plate 1.2 by turning by means of locking levers 2.6 and are secured by nuts 2.7 (FIG. 3, BB ). In this position, the traverse 2.1 is in a fixed and detachable connection with the rotor 1.
- the pulling head 2.2 is connected to the slide 2.4 by a releasable element 2.5, such as an insertable latch, whereby the pulling head 2.2 can be locked in several intervals / positions on the slide 2.4 (FIG. 3, A-A).
- the carriage 2.4 has several insertion positions in this regard.
- the slide 2.4 When the piston rods 2.8.3, 2.8.4 (Fig. La) are retracted, the slide 2.4 is arranged at a distance in the axial direction of the rotor 1 and locked on the anchored rail frame 2.9 in such a way that its dimension divides the length of the respective hammer axis 1.5 plus tolerances corresponds to the required or desired number of strokes (Fig. lc) for pulling the hammer axis 1.5. The resulting position of the carriage 2.4 is locked with the releasable element 2.5 (Fig. Lb).
- the hammer axis pulling device 2 is designed such that after the hammer axis 1.5 has been pulled completely, it lies in the slide 2.4 and can be exchanged for a possibly new hammer axis 1.5, the position of which corresponds to the removal or installation position relative to the rotor 1.
- the hammer axis pulling device 2 designed in this way naturally also serves to install the hammer axes 1.5.
- the method according to the invention for dismantling and reassembling hammers 1.3, hammer axes 1.5 and / or protective caps 1.4 during a repair operation by means of the hammer axis pulling device 2 is implemented by the following process step sequence: a) exposing the rotor 1, which is also mounted in at least part of the housing, and rotating and securing the same to an upper dead center position of the respective hammer axis 1.5,
- Locking lever 2.6 and fastener elements 2.3 of the crossbar 2.1 designed as hammer head screws and secured with nuts 2.7, as well as backing them up in the fastener elements 1.6 of the rotor 1, which are designed as recesses or elongated holes, as a result of which the crossbar 2.1 is fastened to the rotor 1.
- the industrial applicability of the invention is characterized by the fact that a small space is required for disassembly and reassembly, the peripheral devices can be built closer to the system of the hammer crusher which is thus becoming more compact, so that the function according to the invention rationalizes the repair operation and the availability the plant increased.
