[0002] A tunnel is an engineering structure buried in the strata of the earth. It is a form of human utilization of underground space. During tunnel construction, the internal surface needs to be supported. This is usually done by installing support devices inside the tunnel. The existing support devices are equipment installed inside the tunnel to support the construction site. Existing support devices, when used for tunnel construction, directly press the top support main plate against the inner top surface of the tunnel. Therefore, during the support process, after the bottom lifting cylinder fully tightens the support main plate, if the tunnel top is subjected to prolonged stress or external force, causing the support to loosen, it is not convenient to readjust and reinforce the support. This reduces the support effect on the inner top of the tunnel and affects the convenience of the support device for auxiliary support and reinforcement of the inner top during tunnel construction. To address this issue, this utility model proposes a tunnel construction support device. Utility Model Content

[0018] A cleaning mechanism is provided at the end of the side electric cylinder 105 on the side of the base 101. The cleaning mechanism includes a mounting component on the side of the base 101. The outer surface of the mounting component is provided with a cleaning component on the surface of the side electric cylinder 105. When dirt or concrete is attached to the surface of the telescopic end of the side electric cylinder 105 during support treatment, the cleaning mechanism can scrape and clean the dirt on the outer surface of the side electric cylinder 105 during telescopic adjustment.

[0019] In order to facilitate the installation and cleaning of the scraper ring 1052 by means of the mounting component, in this embodiment, preferably, the mounting component includes an external threaded ring 1054 welded and fixed to the side of the base 101, and the telescopic end of the side electric cylinder 105 passes through the interior of the external threaded ring 1054, so that the internal threaded ring 1051 can be rotated to install the scraper ring 1052 for use through the external threaded ring 1054.

[0020] To facilitate the cleaning of objects adhering to the surface of the telescopic end of the side electric cylinder 105 during telescopic adjustment, in this embodiment, preferably, the cleaning component includes an inner threaded ring 1051 threaded to the outer surface of the outer threaded ring 1054. A scraper ring 1052 is integrally provided on the inner surface of the end of the inner threaded ring 1051. The inner surface of the scraper ring 1052 contacts the telescopic end surface of the side electric cylinder 105. Engaging grooves 1053 are provided on both sides of the surface of the inner threaded ring 1051. A wrench can be engaged inside the engagement grooves 1053 to thread the inner threaded ring 1051 inside the outer threaded ring 1054. During telescopic adjustment, the telescopic end of the side electric cylinder 105 contacts the inner surface of the scraper ring 1052 for scraping and cleaning, which is not easily obstructed by dirt or concrete.

[0021] In this utility model, both the side electric cylinder 105 and the lifting electric cylinder 108 are electrically connected to the external power distribution box via wires. The control of the movement of the side electric cylinder 105 and the lifting electric cylinder 108 by the power distribution box is existing technology and will not be described in detail.

[0022] The working principle and usage process of this utility model: Before use, this tunnel construction support device is first placed at the construction position inside the tunnel by the bottom of the base 101. The two lifting electric cylinders 108 are moved simultaneously to drive the limiting main frame 102 and the side support 103 to move upward until the support main plate 104 drives the auxiliary support top plate 1041 and the auxiliary support side plate 1047 to contact the inner surface of the tunnel for support treatment. Then, the side electric cylinder 105 moves to drive the side support plate 106 to move laterally until it is pressed against the side of the tunnel, thereby facilitating the support device to support the inside of the tunnel under construction. Then, when the support device falls off due to long-term support and external force at the top, and the contact is not tight, and the lifting electric cylinder 108 cannot rise again, the wrench can be engaged at the bottom of the adjusting bolt 1044 to drive the adjusting bolt 1044 to rotate. When the adjusting bolt 1044 is rotated, the top frame 1043 moves inside the limiting groove 1042, and the auxiliary support top plate 1041 is lifted up to make tight contact again. At the same time, the same operation is used to adjust the auxiliary support side plate 1047 to make tight contact with the inner surface of the tunnel, which facilitates the auxiliary adjustment for tight support. The auxiliary support is more convenient, and the convenience of the support device for internal top auxiliary support reinforcement during tunnel construction is improved. Finally, when the side electric cylinder 105 drives the side support plate 106 to support the inner side of the tunnel, and when the telescopic end of the side electric cylinder 105 exposes the external surface with dirt attached, the dirt attached to the surface can be scraped off and cleaned by the inner surface of the scraper ring 1052 when the telescopic end of the side electric cylinder 105 moves back to its original position. This makes cleaning more convenient, less prone to damage during repositioning, and less likely to damage the side electric cylinder 105. In addition, the friction generated during scraping is small, which is less likely to damage or obstruct the telescopic end, thus improving the convenience of cleaning the telescopic end of the side electric cylinder 105 during the construction and support of the support device inside the tunnel.
