The first telescopic device 4111, the vertical telescopic column 412 and the third telescopic device 4131 are all connected to the same servo control system 3, and the servo control system 3 is used for adjusting the telescopic amplitude of the first telescopic device 4111, the vertical telescopic column 412 and the third telescopic device 4131, so that the end parts of the first telescopic device 4111, the vertical telescopic column 412 and the third telescopic device 4131 respectively abut against the primary support 2 of the cross section of the tunnel.
According to the invention, the prefabricated reinforcing support 4 is driven to the position of the primary support to be reinforced by the walking device 1, then the reinforcing support 4 is controlled to be stretched and opened by the servo control system 3 and respectively abutted against different positions of the primary support to be reinforced, after the temporary reinforcement is finished, the reinforcing support 4 is contracted, and then the walking device 1 is used for transporting the reinforcing support, so that the construction time of the temporary reinforcement of the primary support can be greatly shortened, the quick temporary reinforcement of the primary support is realized, meanwhile, the reinforcing support 4 is close to the primary support 2 when stretched and opened, a channel in the middle of a tunnel is not occupied, the passage of construction mechanical equipment is allowed, and the tunnel construction progress can be improved.
In the embodiment of the present invention, the first telescopic device 4111 includes two telescopic rods, and the vertical telescopic column 412 is installed on the telescopic rod near the end of the transverse telescopic beam 411. In order to reserve enough space for the channel in the middle of the tunnel, the vertical telescopic column 412 is required to be close to the side wall of the tunnel as much as possible, so the first telescopic device 4111 is selected to be a double-section telescopic rod, the first section of telescopic rod close to the transverse telescopic beam 411 is used for adjusting the transverse moving distance of the vertical telescopic column 412, and the second section of telescopic rod is used for adjusting the distance between the first section of telescopic rod and the side wall of the tunnel.
In the embodiment of the invention, the reinforcing trolley is applied to the mine-method tunnel, and mainly excavates by a drilling and blasting method, so that various sundries, broken stones and the like can be generated on the ground of the tunnel when the reinforcing trolley works in the tunnel, and if a walking device made of common tires is adopted, the tires can be broken and burst, so that the walking device is difficult to move continuously. Therefore, in the present embodiment, the traveling device 1 is a crawler type traveling device, and even if there are foreign materials such as crushed stones, the crawler type traveling device does not greatly affect the operation thereof.
In addition, for better placement of the reinforcing brace 4, the top of the traveling device 1 is provided with a bracket 11, and the bracket 11 is used for supporting the reinforcing brace 4 when transporting/retrieving the reinforcing brace 4. Specifically, as shown in fig. 6, the bracket 11 includes a platform, two longitudinal bars are disposed on the platform, and corresponding grooves are disposed on the longitudinal bars, so that the transverse telescopic beams 411 of the reinforcing bracket 4 can be disposed in the grooves, and the stability of the reinforcing bracket 4 is increased.
In this embodiment, the free end of the first telescopic device 4111 is hinged to a first supporting plate 4112, and the first supporting plate 4112 is used for supporting against the side wall of the primary support 2 when the first telescopic device 4111 is extended.

The contact area between the reinforcing bracket 4 and the primary support 2 can be increased by the first supporting plate 4112, the second supporting plate 4122 and the third supporting plate 4132, and thus the stability of the temporary support can be increased. Furthermore, the possibility of prestressing the primary branch 2 is also increased. If the supporting plate is not arranged, the telescopic device exerts force outwards, and meanwhile, the surface area of the telescopic head of the telescopic device is small, if the applied telescopic force is large, the surface of the primary support 2 can be stabbed and even broken, so that the supporting plate is added, and the risk cannot occur.
Furthermore, since the surface of the primary support 2 is a cambered surface, the first supporting plate 4112, the second supporting plate 4122 and the third supporting plate 4132 are respectively hinged with the telescopic device, so that even if the supporting plates are inclined to some extent when they are in contact with the surface of the primary support 2, the telescopic device can be extended and the orientation of the supporting plates can be adjusted to firmly abut against the surface of the primary support 2. In order to further increase the contact surface, the shape of the supporting plate can be processed into an arc surface with the same radian as the surface of the primary support 2, so that the supporting plate is more attached to the surface of the primary support when the telescopic device extends out.

The servo control system 3 is used for disconnecting the first telescopic device 4111, the vertical telescopic column 412 and the third telescopic device 4131 when the reinforcing bracket 4 temporarily reinforces the primary support 2.
When each telescopic device needs to be controlled, the servo control system 3 is connected with signal line interfaces and other application interfaces of each telescopic device, so that the reinforcing support 4 is controlled. When the reinforcing bracket 4 is stabilized to temporarily reinforce the primary support 2, the servo control system 3 and the interfaces of the respective telescopic devices can be disconnected, so that the telescopic devices are evacuated along with the traveling device 1. Thus, even if the primary support 2 unexpectedly collapses or the like, the servo control system 3 is not lost. In this embodiment, each telescoping device can select jack, hydro-cylinder, electric putter etc. as required by oneself.
