Movable crushing equipment

describe

The invention relates to a movable breaking plant (Brechanlage) according to the preamble of claim 1 .

运送到固定的卸料输送带或者另一个与可活动的破碎设备不同的装置中。在通过上游的挖土机为可活动的破碎设备进行的加料过程(Beladungsvorgang)中，挖土机在实际的挖掘过程和随后的将所得挖掘物转移到装料斗或接收料斗之间要完成至少一次水平的回旋运动。在该回旋运动期间，经常会有较小和较大的挖掘物部分从挖斗中掉落到挖土机与可活动的破碎设备之间的路基(Planum)上。另外，在挖掘过程期间，还可能有大块的部分从挖掘前端(Grabfront)脱落，随后滚到路基上。为了使可活动的破碎设备在开采进展中能够跟随上挖土机的位置，其行车路线上就必须始终没有相应的大块挖掘物部分。否则这些之前掉落在该路线上的大块挖掘物部分能够处于可活动的破碎设备的履带式车辆链条下，并引起履带式行走装置的损坏。为了这个目的，目前为止可活动的破碎设备必须以规则的距离相对其工作方向或前进行驶方向回撤，这样，通过较小的平地车(Planierfahrzeug)能够对前进行驶方向上的路线进行清理。不但由于清洁中断，而且由于可能的因损坏的履带式行走装置所引起的修理工作，都会产生出成本高昂的停工期。A movable crushing device of this type is known from DE 10314958 A1. A crushing device has been described therein which is used in particular as a mobile or semi-mobile unit in the surface mining and recycling industry. Such movable crushing plants are preferably used in surface mining. It works directly downstream of mining equipment such as shovels or backhoes. The bucket of the mining plant loads the excavated material into the loading hopper of the movable crushing plant. The crushing device in the movable crushing equipment crushes the obtained excavated materials to a particle size range suitable for transportation. The crushed excavated material then passes through the transfer conveyor belt

Transported to a fixed discharge conveyor or another device different from the movable crushing equipment. In the feeding process (Beladungsvorgang) for movable crushing equipment by an upstream excavator, the excavator completes at least once between the actual excavation process and the subsequent transfer of the resulting excavated material to a charging or receiving hopper Horizontal roundabout motion. During this pivoting movement, small and large parts of the excavated material often fall out of the bucket onto the road bed (Planum) between the excavator and the movable crushing device. In addition, during the excavation process, it is also possible for large pieces to break off from the digging front (Grabfront) and subsequently roll onto the roadbed. In order for the movable crushing device to follow the position of the excavator during mining progress, its driving path must always be free of corresponding large parts of the excavated material. Otherwise, parts of these large excavated objects that have previously fallen on this route could get under the tracked vehicle chain of the movable crushing plant and cause damage to the tracked undercarriage. For this purpose, hitherto movable crushing plants had to be withdrawn at regular distances relative to their working direction or forward direction of travel, so that the path in the forward direction of travel could be cleared by means of smaller flatbed vehicles. Costly downtimes arise not only due to interruptions in cleaning, but also due to possible repair work caused by a damaged crawler track.

The object of the present invention is to create a movable crushing plant by means of which costly downtimes can be avoided as much as possible.

According to the invention, this task is achieved by a movable crushing plant having the features of the independent claims. Advantageous refinements are to be found in the subclaims. According to the invention, each tracked chassis is preceded by a deflection stop. The installation of the diverting apron has the advantage that, viewed in the longitudinal extent of the crushing plant, the apron is installed between the front-mounted receiving hopper and each crawler travel unit assigned to it. Objects or excavated debris lying on the path can thus be automatically cleared from the path during operation of the movable crushing plant and kept away from the traction chain and the drive unit of the tracked chassis. Each turning fence shall be measured and maintained such that its effective width, or the distance of its side fence edge measured perpendicular to its forward direction of travel, is greater than the tracked running gear or track chain to be protected width. It is advantageous if the deflection panel is adjustable in its height and/or angle. In addition, the deflection panels of two tracked chassis mounted parallel to one another and mounted mirror-symmetrically with respect to the longitudinal axis of the vehicle can be oriented differently or (also fixedly) mounted.

In the first embodiment of the present invention, the steering baffle starts from a position installed vertically or orthogonally to the longitudinal axis of the vehicle and slopes away from the midpoint of the vehicle so as to form an arrow shape (with (open) arrow pointing in the direction of travel).

In another embodiment of the present invention, the steering baffle is reversely installed compared with the first embodiment, and is inclined towards the direction of the midpoint of the vehicle, thereby forming a funnel shape when viewed in the direction of forward travel (with a Oppositely pointing (open) arrows).

Finally, the diverting flaps can also be oriented in the same way, so that in the forward direction of travel, the material to be cleaned is guided inwardly by the diverting flap between the two tracked undercarriages and directed toward the rear by the other diverting flap. The outer guide is sent to the side of the assigned crawler running gear.

In a further embodiment of the invention, the movable crushing plant has a third crawler-type running gear, which is actually mounted on two parallel and mirror-symmetrical with respect to the longitudinal axis of the vehicle, viewed in the direction of forward travel. In the middle front of the crawler, the third crawler is likewise assigned a deflection paddle. The deflector of the third crawler advantageously has the shape of an arrow pointing in the forward direction of travel.

In a further embodiment of the invention that has not been described, one or each deflection barrier has a top plate (also at least partially closed upwardly), so that Excavation debris must not fall between the deflector fence and the tracked undercarriage.

Further advantages, features and suitable embodiments of the invention can be seen from the dependent claims and the following description of the figures.

The attached picture shows:

1-5 show in explanatory views different embodiments of the movable crushing plant according to the invention.

Figure 1 shows a first possible embodiment of the mobile crushing plant according to the invention. The mobile crushing plant actually consists of two crawler-type running gear 2 and a supporting frame 4 connected thereto which is mounted on or carried by another structure. The other structure actually comprises a material receiving arm 6 carried by the support frame 4 , a crushing device 8 carried by the support frame 4 and a material transfer arm 10 carried by the support frame 4 . Wherein, the material receiving arm 6 actually consists of a conveyor belt 6a and a receiving hopper 6b. The crushing device 8 practically also corresponds to a conventional pulverizer device especially for mineral excavations. The material transfer arm 10 actually comprises only another conveyor belt 10a through which the ground material is carried away and can be transferred to another device 12, for example a stable conveyor belt. According to the invention, the mobile crushing plant comprises, in front of each crawler running gear 2 , on its face facing away from the material transfer arm 10 , a separate deflection fence 14 . According to the illustrated embodiment, the deflector baffle 14 is mounted on the support frame 4 of the movable crushing plant by means of fixing means 14a. In this case, the fastening device 14 a can also be realized, for example, as a hydraulically or pneumatically operable telescopic arm. On the one hand, each deflection flap 14 can be adjusted both horizontally and vertically via the telescopic arm. On the other hand, it is also possible to change each deflector flap 14 with reference to the tilted state or transverse state (with reference to the forward travel direction V) of the deflector flap 14 by means of the fixing device 14a. Alternatively or additionally, one or each fixed apron 14 can also be fixed to the crawler chassis 2 or to the material receiving arm 6 .

The bucket S of the excavator performs at least one horizontal pivoting movement between the actual excavation process and the subsequent transfer of the resulting excavated material to the receiving hopper 6b of the mobile crushing plant. During the swinging motion, there are often smaller and larger parts of the excavated material falling out of the bucket S onto the plane P between the excavator and the pulverizer. During the mining progress, the movable crushing equipment follows the real-time position of the excavator. Parts of larger excavations that fell on the route before will be cleared from the route by means of the diverting baffle 14 according to the invention, so that they can no longer reach under the chains of the crawler 2 of the movable crushing plant and cannot be placed in the Unnecessary damage is caused there. Unnecessary shutdowns of the entire extraction plant and subsequent transport equipment for maintenance and repair purposes are thereby avoided.

FIG. 2 shows a plan view of the movable crushing plant shown in FIG. 1 . According to this embodiment, the deflection panel 14 is mounted in such a way that it forms an arrowhead pointing in the forward direction of travel V (opened by the arrow).

In the embodiment according to FIG. 3 , the deflection flap 14 is installed in such a way that it forms a funnel shape when viewed in the forward direction of travel V (or in the shape of an arrow with an open arrow pointing opposite to the direction of forward travel). The excavated objects to be cleaned are guided into the open space between the two crawler-type running gear 2 of the movable crushing plant.

In FIGS. 4 and 5 a mobile crushing plant with a total of three crawler units 2 is shown. Among them, the third crawler-type traveling device is actually installed in the middle of the two parallel and mirror-symmetrical crawler-type traveling devices with respect to the longitudinal axis X of the vehicle when viewed from the forward driving direction, among which the third crawler-type traveling device is The device 2 is likewise assigned a deflection flap 14 . In this case, the deflection flap 14 of the third crawler 2 has the shape of an arrow pointing in the forward direction of travel V (with a substantially closed arrow).

All deflector flaps 14 involved can consist of a single or multiple deflector flap parts. Likewise, all embodiments of the deflector apron 14 in question have an effective width W extending perpendicular to the forward direction of travel and acting in the forward direction of travel between the outer and side edges of the deflector apron 14 , which The effective width W is greater than the width B of the crawler chassis B to be supported or of the crawler chain and its drive unit A to be supported.
