[0016] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0017] The utility model discloses a top guard plate for protecting a trailer of tunnel boring equipment. The top guard plate for protecting a trailer of tunnel boring equipment mainly comprises a foldable support frame 1, an arc-shaped guard plate 2, and a connecting seat 3. The support frame 1 comprises a column 101, a crossbeam 102, a connecting rod 103, and a limit block 104. The connecting seat 3 is provided on the inner wall of the arc-shaped guard plate 2. The crossbeam 102 is installed on the connecting seat 3 by bolts. The top of the column 101 is hinged to the crossbeam 102. At the end, the cross-sections of the column 101 and the beam 102 are both U-shaped structures, one end of the connecting rod 103 is hinged on the column 101, and the other end is slidably installed in the straight slot 1021 on the beam 102, the limit block 104 is hinged on the beam 102 and close to the straight slot 1021 section on the side of the column 101, the length between the end of the limit block 104 and the hinge point is greater than the slot height of the beam 102, and U-shaped limit slots 1011 are provided on both the column 101 and the beam 102.

[0018] When tunnel excavation is carried out, the support frame 1 on the arc-shaped protective plate 2 is opened, and the operator rotates the column 101 so that the column 101 and the beam 102 are in a vertical state. At this time, the connecting rod 103 is located at the end of the straight notch 1021. Then, the limit block 104 is rotated so that its end abuts against the end of the connecting rod 103, thereby fixing the connecting rod 103 on the beam 102, ensuring the stability of the arc-shaped protective plate 2. Finally, the bottom end of the column 101 is installed on the frame of the tunnel excavation equipment; During the shotcrete operation, the rebound material generated will be blocked by the arc-shaped protective plate 2 and slide down along the arc-shaped protective plate 2, thereby protecting the trailer, ensuring the normal operation of the trailer, and reducing the occurrence of safety accidents; when the top guard plate needs to be folded, it is only necessary to rotate the limit block 104 in the opposite direction to release the limiting effect on the connecting rod 103, slide the connecting rod 103 along the straight slot 1021 to its other end, and rotate the column 101 to fold it up, which can save space and facilitate transportation and storage.

[0019] The arc-shaped protective plate 2 includes a first arc-shaped plate 201 and a second arc-shaped plate 202. The contact ends of the first arc-shaped plate 201 and the second arc-shaped plate 202 are provided with connecting blocks 2011, and the connecting blocks 2011 are connected by bolts. The detachable design makes the installation and transportation of the arc-shaped protective plate 2 in the tunnel more convenient.

[0020] A base plate 1012 is welded to the bottom end of the column 101, and a through hole is opened on the base plate 1012 for bolts to pass through; the base plate 1012 is fixed to the frame of the excavation equipment by bolts, which increases the stability and firmness of the column 101; in addition, the bolt connection is detachable, which facilitates the disassembly and assembly of the column 101.

[0021] Working process:

[0022] When tunnel excavation is carried out, the support frame 1 on the arc-shaped protective plate 2 is opened, and the operator rotates the column 101 so that the column 101 and the beam 102 are in a vertical state. At this time, the connecting rod 103 is located at the end of the straight slot 1021. Then, the limit block 104 is rotated so that its end abuts against the end of the connecting rod 103, thereby fixing the connecting rod 103 on the beam 102, ensuring the stability of the arc-shaped protective plate 2. Finally, the bottom end of the column 101 is installed on the frame of the tunnel excavation equipment by bolts. ; During the shotcrete operation, the rebound material generated will be blocked by the arc-shaped protective plate 2 and slide down along the arc-shaped protective plate 2, thereby protecting the trailer, ensuring the normal operation of the trailer, and reducing the occurrence of safety accidents; when the top guard plate needs to be folded, it is only necessary to rotate the limit block 104 in the opposite direction to release the limiting effect on the connecting rod 103, slide the connecting rod 103 along the straight slot 1021 to its other end, and rotate the column 101 to fold it up, which can save space and facilitate transportation and storage.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
