Description

Technical Field

[0001] The present invention relates to the technical field of tunneling equipment for underground coal mine tunneling working faces, and in particular to a belt transfer machine connection device. Background Art

[0002] The belt transfer machine is composed of a machine head, an intermediate connecting frame, a machine tail, a supporting trolley, etc. It is a transfer equipment in the mechanical complete coal mining and transportation system and is used to be installed at the tail of the tunneling machine.

[0003] The existing connection method between the belt transfer machine and the tunnel boring machine is to connect the ear frame with the tunnel boring machine flange bolts, and the ear frame and the transfer machine tail frame are connected by a cross joint and a pin shaft. This connection method allows the transfer machine to swing left and right and have a certain degree of freedom in the up and down floating direction. However, when the tunnel boring machine has a large uphill and downhill angle, or when the tunnel boring machine and the transfer machine have a large horizontal angle, the tunnel boring machine and the transfer machine are prone to collision and interference problems. At the same time, the cross joint connection method is prone to stress concentration, causing the ear frame and the connecting pin shaft to break, affecting the progress of the engineering operation. To this end, we propose a belt transfer machine connection device that can effectively solve the above situation. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a belt transfer machine connecting device.

[0005] The present invention provides a belt transfer machine connection device, comprising a connecting ear frame 1, a pin shaft 2, a bracket 10, a baffle plate 7 and a connecting rod 11, which is installed between a transfer machine 14 and a tunnel boring machine 12. The connecting ear frame 1 is installed behind the tunnel boring machine 12 by bolts, the bracket 10 is connected to the connecting ear frame 1 by the pin shaft 2, and the bracket 10 is connected to the tail frame of the transfer machine 14 by the connecting rod 11 and the baffle plate 7.

[0006] Optionally, the connecting ear frame 1 is processed with a through hole on the connecting plate for installing bolts, and a rib plate is welded between the main board and the connecting plate to increase its mechanical strength.

[0007] Optionally, the front part of the bracket 10 adopts a duckbill structure, which is connected to the connecting ear frame 1 through a pin 2; the middle part is a frame structure with stable mechanical strength; the rear part is a fork frame structure, which is connected to the tail frame of the transfer machine 14 through a connecting rod 11.

[0008] Optionally, the top of the connecting rod 11 is designed with a baffle 7 embedded in it to facilitate fixing the position of the connecting rod 11; and an oil filling port is processed on the top for filling lubricating oil.

[0009] Compared with the prior art, the technical solution provided by the embodiments of the present disclosure has the following advantages:

[0010] The present invention provides a belt transfer machine connection device with a stable structure and high mechanical strength. It is suitable for connecting transfer machines with large conveying capacity and subsequent dust removal equipment. The total length of the connection device is 1500 mm, which increases the distance between the transfer machine and the tunnel boring machine 12, avoids collision and interference between the two, and increases the service life of the transfer machine and the tunnel boring machine 12. The pin shaft 2 is provided with a lubrication device, which reduces the friction between the pin shaft 2 and the connecting ear frame 1 and the bracket 10, reduces the wear of parts, and increases the service life of the device.
