Abstract
Description
Technical Field
[0001] The invention relates to an auxiliary bracket of a self-propelled hard rock tunneling machine. Background Art
[0002] With the rapid development of the rail transit industry, tunnel boring machines have been widely used in municipal, transportation, water conservancy and other projects.
[0003] At present, special running tracks are laid according to the specific shape of the tunnel to realize the start and transfer of the tunnel boring machine. When the tunnel boring machine is started and transferred, special running tracks are usually laid according to the specific shape of the tunnel section to facilitate the movement of the equipment. However, the laid tracks cannot be reused, which wastes materials and increases the remanufacturing cost. Summary of the invention
[0004] In order to solve the problem of mutual conversion between the horizontal ground and the walking surface of tunnels with different cross-sections (including circular tunnels, horseshoe-shaped tunnels, etc.) of the crawler-type self-propelled mechanism during the process of starting and transferring in and out of the tunnel for a self-propelled hard rock tunnel boring machine, and realize the efficient and rapid starting and transfer of the self-propelled tunnel boring machine, thereby comprehensively reducing the remanufacturing cost, the present invention provides an auxiliary bracket of a self-propelled hard rock tunnel boring machine, and the technical solution of the present invention is:
[0005] The auxiliary bracket of the self-propelled hard rock tunnel boring machine includes a base, a supporting cylinder, an adjusting cylinder and a supporting plate. A supporting cylinder installation area is formed in the middle of the base, and a plurality of supporting cylinder installation grooves are opened in the supporting cylinder installation area. A supporting cylinder is installed in each of the supporting cylinder installation grooves, and a supporting plate is installed on the piston rod of the supporting cylinder; a supporting plate is respectively arranged on the base on both sides of the supporting cylinder installation area, and each supporting plate is hinged to the base, and the two supporting plates are symmetrically arranged along the supporting cylinder installation area, and an adjusting cylinder is installed in the base at the lower part of each supporting plate, and the supporting plate is driven by the adjusting cylinder.
[0006] There are several adjusting oil cylinders, which are arranged along the length direction of the support plate; an oil cylinder seat is installed on the base, and the cylinder body of each adjusting oil cylinder is hinged on the oil cylinder seat, and the rod body is hinged on the support plate.
[0007] The base is in a rectangular shape as a whole, and grooves are arranged along the periphery of the base.
[0008] The invention has the advantages that when the self-propelled hard rock tunnel boring machine is starting and transferring, it can efficiently and quickly realize the back and forth conversion between the tunnel walking surface of different cross sections and the horizontal ground, thereby improving the overall construction efficiency and reducing the cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1It is a schematic diagram of the main structure of the present invention.
[0010] Figure 2 It is a schematic diagram of the process flow of the present invention when it works. DETAILED DESCRIPTION
[0011] The present invention will be further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the scope of protection of the present invention.
[0012] See also Figure 1 and Figure 2 The present invention relates to an auxiliary bracket of a self-propelled hard rock tunnel boring machine, comprising a base 1, a supporting cylinder 2, an adjusting cylinder 3 and a supporting plate 4. A supporting cylinder installation area is formed in the middle of the base 11, and a plurality of supporting cylinder installation grooves are provided in the supporting cylinder installation area. A supporting cylinder 2 is installed in each of the supporting cylinder installation grooves, and a supporting plate is installed on the piston rod of the supporting cylinder 2 to support the passing walking mechanism; a supporting plate 4 is respectively arranged on the bases on both sides of the supporting cylinder installation area, and each supporting plate 4 is hinged to the base 1, and the two supporting plates 4 are symmetrically arranged along the supporting cylinder installation area, and an adjusting cylinder 3 is installed in the base at the lower part of each supporting plate 4, and the supporting plate 4 is driven by the adjusting cylinder 3.
[0013] There are several adjusting cylinders 3. The present invention takes the example that each support plate is driven by four adjusting cylinders, which are arranged along the length direction of the support plate 4. A cylinder seat is installed on the base 1, and the cylinder body of each adjusting cylinder 3 is hinged on the cylinder seat, and the rod body is hinged on the support plate 4.
[0014] The base 1 is in a rectangular shape as a whole, and grooves are arranged along the periphery of the base.
[0015] The working principle of the present invention is:
[0016] First, the crawler-type self-propelled mechanism moves from the horizontal ground to the auxiliary bracket;
[0017] In the second step, the supporting cylinder extends to lift the entire mechanism;
[0018] The third step is to keep the support cylinder extended, and adjust the extension amount of the cylinder according to the diameter and cross-section of the tunnel, so that the crawler self-propelled mechanism is tangent to the tunnel walking surface;
[0019] The fourth step is to keep the adjustment cylinder extended, retract the support cylinder, and move the crawler self-propelled mechanism into the tunnel. Conversely, when the crawler self-propelled mechanism exits the tunnel and enters the horizontal ground, the opposite of the above scheme can be completed.
