Description

The invention relates to a device for vulcanizing conveyor belt connections within or near a conveyor system with a press that can be driven on a chassis and that has two press frames that can be pressed against one another and that have columns separable press plates.

When vulcanizing the connection points of very wide conveyor belts with the previously known mobile vulcanizing devices (cf. British patent specification 641 043), considerable difficulties arise in terms of temperature distribution, especially at the plate joints. Another disadvantage of the known mobile vulcanizing devices is the difficulty of assembling the many individual parts and the associated high personnel requirements. There are, for example, conveyor belts with a width of 3000 mm and a connection length of about 3.5 m. Before the necessary vulcanizing device of known design would have a total weight of 12 to 14 tons and would have to be transported in individual parts and at the assembly point by hand or with a Special crane can be assembled. Since the hydraulic pressure of the vulcanizing ^{device would have to be increased from about 10 kp / cm 2} to 15 kp / cm ² , a considerable increase in the moment of resistance in the crossbeams is necessary in addition to the enlargement of the area. Despite its high price, this vulcanizing device is only suitable for making connections.

The invention is based on the object of a

To vulcanize long conveyor belt connections in the case of wide conveyor belts, to create suitable grooves that are ready for use at any time and with which vulcanization can be carried out with little effort.

In a device of the type mentioned at the outset, the object of the invention is that the drive system is designed for trackless driving of the press and the lower press plate is assigned an auxiliary plate that can be accommodated in the press as a vulcanizing mold as a base for making the conveyor connection.

For the implementation! tion of the vulcanization, the press is driven over the joint and the auxiliary plate placed between the lower pressing plate and the conveyor belt ends to be joined.

The press is not only suitable for vulcanizing conveyor belt connections, but also for carrying out repairs on the conveyor belt. These repairs can be carried out inside the conveyor system without removing the conveyor belts or opening connections.

Another useful embodiment of the device according to the invention is that for Receiving the auxiliary plate on each press frame at least one column part can be folded out laterally and can be locked in the folded-in state, so that the conveyor belt can be inserted laterally into the press when the press is approached to the connection point without the press being disassembled must become.

From the German patent 532 816 a vulcanizing press is already known in which the Columns located on one side can be lowered by hydraulic cylinders in order to access them Way to open the press room to one side. The hydraulic actuation of the columns requires a "relatively high structural effort. Furthermore, this press is not designed to be mobile.

According to a further development of the device according to the invention are with the chassis of the press the required hydraulic pumps and switching devices can also be moved. As a result, only one electrical connection is necessary for moving and operating the press.

To reduce the weight of the press, the press frames are thin-walled and proportionate arranged in large numbers.

In a further embodiment of the invention, a relatively large number of press cylinders are assigned to the press plates for applying the press pressure this measure results in a further saving in weight and a reduction in the overall height.

The last two features of the invention are already known from a standing press (patent 33 057 of the Office for Invention and Patents in East Berlin). No protection is sought for these features, nor for the feature known in part from German patent specification 532 816, but only in connection with the other features of the claims.

The invention is explained in more detail with reference to the drawing. It shows

As shown in FIGS. 3 and 4, the mobile press is retracted into the conveyor system after the lower run of the conveyor 5 has been lowered and the roller stations or structural parts have been removed, if necessary on the lowered interior. the upper part of the conveyor belt 5 arranged on the auxiliary plate 4 being introduced into the press. Around. the auxiliary plate 4 with the upper run of the conveyor belt 5 arranged thereon ^; n insert the press / u can, the Säulencile 6 are folded out. One of the pillars 6 is in the V i ü. 5 undo shown on a larger scale. The auxiliary plate 4 is partially supported during the manufacture, connection and start-up of the press by support frames which are arranged outside the start-up area of the press.

The press can be heated from a unit carried on a special vehicle, which also enables the press to be cooled at the same time. The press can also be heated electrically. In this case no separate vehicle is required .. -I.
