[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a support mechanism for suspended rail equipment, which can ensure that each support mechanism can be firmly supported on the tunnel ground or top by adjusting the extension state of each support swing angle cylinder, thereby meeting the requirements of the working stability of the whole machine, and can also ensure construction safety and significantly improve construction efficiency.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1:

[0036] like Figure 1-4 As shown, this embodiment provides a support mechanism for a suspended rail device, including a suspended rail platform assembly 1, a front support mechanism 2, a rear support mechanism 4, a driven wheel assembly 9 and a connecting rod assembly 10. Figure 1 As shown, the suspension rail 6 is suspended on the top of the tunnel through the existing hanging assembly 7; a plurality of driven wheel assemblies 9 are provided on the top of the suspension rail platform assembly 1, the top of the driven wheel assembly 9 is connected to the suspension rail 6 in a rolling manner, and the bottom of the driven wheel assembly 9 is connected to the suspension rail platform assembly 1 through a slewing support. The plurality of driven wheel assemblies 9 are sequentially connected through a connecting rod assembly 10, and the two ends of the connecting rod assembly 10 are respectively hinged to the driven wheel assembly 9. The suspension rail platform assembly 1 is also provided with a driving component, which drives the driven wheel assembly 9 to move along the suspension rail 6 through the relevant driving components to adjust the position of the suspension rail platform assembly 1 on the suspension rail 6. The front support mechanism 2 rotates within a range of 90 degrees under the drive of the front support angle mechanism, as shown in FIG. Figure 1 As shown, it can be retracted to a horizontal state and suspended at the front end of the combined platform (non-working state), or it can be supported vertically on the roadway ground. The rear support mechanism 4 is preferably arranged in a bilaterally symmetrical manner at the rear of the suspended rail platform assembly 1 (working state). Figure 3-4As shown, the rear support mechanism 4 can also be rotated within a range of 90 degrees under the drive of the rear support corner mechanism 5. It can be retracted into a horizontal state and folded into the lower part of the combined platform (non-working state), and can also be supported in a vertical state on the tunnel floor or supported in a vertical state between the tunnel floor and the tunnel top at the same time (working state).

[0037] In this embodiment, Figure 1 As shown, the front support angle mechanism 3 is preferably a front support angle cylinder, the top of the front support angle cylinder and one end of the front support mechanism 2 are respectively hinged to the top and bottom of the platform component mounting seat 8, and the piston end of the front support angle cylinder is hinged to the middle of the front support mechanism 2. Based on this, the front support mechanism 2 can be retracted into a horizontal state and suspended at the front end of the platform component or unfolded into a vertical state and supported on the tunnel ground under the extension and contraction of the front support angle cylinder.

[0038] Similarly, the rear support corner mechanism 5 is preferably a rear support corner cylinder, one end of the rear support corner cylinder and one end of the rear support mechanism 4 are both hinged to the middle of the suspension rail platform assembly 1, and the other end of the rear support corner cylinder is hinged to the middle of the rear support mechanism 4. Based on this, the rear support mechanism 4 can be folded to a horizontal state under the extension and contraction of the rear support corner cylinder to be folded to the bottom of the suspension rail platform assembly 1, or unfolded to a vertical state to be supported on the tunnel ground, or supported in a vertical state between the tunnel ground and the tunnel top at the same time.

[0039] In this embodiment, Figure 4 As shown, the rear support mechanism 4 can be composed of two components: an upper support mechanism 42 and a lower support mechanism 41. The lower support mechanism 41 is hinged to the rear support corner mechanism 5, and the upper support mechanism 42 is fixed to the side of the lower support mechanism 41 opposite the rear support corner mechanism 5. Based on this, the upper support mechanism 42 can move with the lower support mechanism 41 and then, depending on actual construction requirements, can choose to support the space between the tunnel top and the suspension rail platform assembly or not. The upper support mechanism 42 can also be set on the suspension rail platform assembly 1 and driven by a dedicated corner drive mechanism to switch between the folded state and the extended working state.

[0040] In this embodiment, Figure 5-7 As shown, the front support mechanism 2 includes a front left support mechanism 21, a front right support mechanism 22, and a front middle support mechanism 23, and the front left support mechanism 21, the front middle support mechanism 23 and the front right support mechanism 22 are all rotatably connected to the front part of the suspension rail platform assembly 1, that is, the platform assembly mounting seat 8. In actual construction, one of the three forms of left-right symmetrical distribution of two mechanisms, middle distribution of a single mechanism, or left-center-right interval distribution of three mechanisms can be adopted according to needs.

[0041] In this embodiment, the front left support mechanism 21, the front right support mechanism 22, the front center support mechanism 23, and each rear support mechanism are all capable of axial extension and retraction, and can be rotated upward to a horizontal position (non-operating state) or downward to a vertical position (operating support state) under the control of their respective angular cylinders. Each support mechanism can preferably be a hydraulic cylinder or an electric retractable mechanism, and can be hydraulically retractable or electrically retractable. Each support mechanism and angular cylinder utilizes a pin-shaped articulated connection, which is not only reliable in operation but also easy and convenient to assemble and disassemble.

[0042] As can be seen, the support mechanism for the suspended rail equipment provided in this embodiment has front and rear support mechanisms installed on the platform assembly of the suspended rail equipment, which can provide downward support or downward and upward support according to work needs (the front upward support can be replaced by a support platform supporting the tunnel roof). These support mechanisms are retractable and foldable. When the front support mechanism is folded, it is suspended horizontally at the front end of the platform assembly, and when the rear support mechanism is folded, it is hidden horizontally at the bottom of the platform assembly. After the suspended rail platform assembly is stably supported by the above-mentioned support mechanisms, it not only ensures the normal operation of the working mechanisms such as the rock drill boom, anchor drill boom, or excavation working arm installed on the platform, but also achieves the same stable working environment for the suspended rail equipment as the ground equipment, achieving parallel operation with the tunnel lower excavation equipment, eliminating the long auxiliary time caused by "passing vehicles" and safety accidents such as equipment collisions caused by "passing vehicles", significantly improving construction efficiency and enhancing practicality.
