Description

Technical field:

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a turnaround structure of a walkway of a papermaking machine. Background technology:

[0002] In the field of paper machine walkways, a large number of walkway flip structures are used. During the overhaul and maintenance of paper machines, parts need to be replaced, but the replacement space of some parts is opposite to the walkway, and the walkway needs to be dismantled for replacement, which is labor-intensive and inefficient. Utility model content:

[0003] The technical problem to be solved by the utility model is that the existing fixed walkway conflicts with the maintenance space of the paper machine, and the fixed walkway needs to be dismantled during maintenance, which results in high labor intensity and reduced work efficiency.

[0004] In order to solve the above technical problems, the utility model provides a technical solution: a paper machine walkway turning structure, comprising a fixed walkway, a turning walkway and a rotating mechanism, characterized in that: a support plate is arranged at the lower side of one end of the fixed walkway, one end of the turning walkway is placed on the support plate and aligned with the end of the fixed walkway, and is hinged with the end of the fixed walkway through a rotating mechanism, so that the turning walkway can turn upward, and the other end of the turning walkway is suspended;

[0005] The flipping platform includes a connecting plate, a rotating shaft and a reinforcing plate, one end of the rotating shaft is connected to the reinforcing plate, the other end of the rotating shaft passes through the fixed platform and is hinged to one end of the connecting plate, the other end of the connecting plate is connected to the flipping platform, and the reinforcing plate is connected to the fixed platform.

[0006] Furthermore, an upper corner of one end of the fixed walkway and a lower corner of a hinged end of the connecting plate and the rotating shaft are chamfered.

[0007] The beneficial effects of the utility model are:

[0008] 1. The present application improves upon the existing fixed walkway by hingedly connecting a flip walkway at its end. The flip walkway can serve as a walkway during normal production, and the flip walkway flips upward to make room when replacing parts. The existence of the flip structure reduces the production and maintenance costs of the paper machine in the later stage, and there is no need to dismantle the fixed walkway, which reduces the workload and improves work efficiency.

[0009] 2. In the present application, one end of the flip walkway is placed on the support plate at the end of the fixed walkway and is hinged to the fixed walkway. The support plate plays the role of support limit. When the flip walkway is working normally, the flip walkway is supported by the rotating shaft, the connecting plate and the support plate to ensure the stability of the work.

[0010] 3. In the present application, one end of the rotating shaft is connected to the reinforcing plate, and after the rotating shaft passes through the side wall of the fixed walkway, the reinforcing plate is connected to the fixed walkway through screws or rivets, thereby increasing the connection stability of the rotating shaft.

[0011] 4. The upper corner of one end of the fixed walkway described in the present application and the lower corner of the hinged end of the connecting plate and the rotating shaft are chamfered to prevent the protruding corners from interfering with the flipping when the flipping walkway rotates upward.

[0012] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. Description of the drawings:
