Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drilling and grouting equipment, in particular to a truss mechanism of an integrated tunnel drilling and grouting device. Background Technique

[0002] During the tunnel construction process, the ground is usually reinforced by bolt grouting when the formation is weak, and drilling operations are required during the construction. Especially in shield construction in soft soil areas, in order to enhance the bearing capacity of the formation, formation grouting reinforcement is carried out synchronously during the segment assembly process. In order to meet the high-efficiency construction of shield tunneling, an integrated drilling and grouting device system needs to be designed to complete the drilling and grouting construction when segment assembly is carried out at the shield tail. The integrated drilling and grouting device system includes a modular bolt drilling device. The modular bolt drilling device realizes the drilling operation through the drill arm unit. Therefore, a reliable truss platform must be available to support the drill arm and at the same time meet the movement of the drill arm between different hole positions.

[0019] The features of the present utility model and other related features are further described in detail below in conjunction with the accompanying drawings through examples for the understanding of those skilled in the same industry:

[0020] As Figures 1 - 8 shown, the marks in the figure are respectively represented as:

[0022] Example: As Figures 1 - 8As shown in the figure, this embodiment relates to a truss mechanism of a tunnel drilling and grouting integrated device, which mainly includes a crossbeam of the trolley frame 1, a track beam assembly 2, a crossbeam walking mechanism assembly 3, a drilling rig crossbeam mechanism 4, a drilling rig walking mechanism 5, an operating platform mechanism 6 and an operating platform walking mechanism 7. The double-arm drilling rig is installed on the drilling rig walking mechanism 5. The double-arm drilling rig includes an anchor drilling rig and a steel pipe grouting drilling rig, and the double-arm drilling rig is connected to the drilling rig walking mechanism 5 through a flange. There are two sets of the crossbeam of the trolley frame 1 and the drilling rig crossbeam mechanism 4 respectively. One track beam assembly 2 is installed on each crossbeam of the trolley frame 1, and the crossbeam of the trolley frame 1 and the track beam assembly 2 are welded. One drilling rig crossbeam mechanism 4 is provided at the same end of the two crossbeams of the trolley frame 1. Each end of the drilling rig crossbeam mechanism 4 is connected to a crossbeam walking mechanism assembly 3, and the drilling rig crossbeam mechanism 4 and the crossbeam walking mechanism assembly 3 are connected by bolts. The crossbeam walking mechanism assembly 3 is installed on the track beam assembly 2 and moves along the length direction of the track beam assembly 2. One drilling rig walking mechanism 5 is provided at the bottom of each drilling rig crossbeam mechanism 4, and the drilling rig walking mechanism 5 moves along the length direction of the drilling rig crossbeam mechanism 4. Among them, the movement of the drilling rig walking mechanism 5 ensures the walking of the double-arm drilling rig in the radial direction of the tunnel axis to cooperate with the anchor holes arranged at different angles on the same cross-section of the tunnel; the movement of the crossbeam walking mechanism assembly 3 ensures the movement of the double-arm drilling rig along the tunnel axis direction to cooperate with the anchor holes and steel pipe grouting reinforcement drilled at different spacings in the tunnel axis direction. The operating platform mechanism 6 is arranged in the middle of the two crossbeams of the trolley frame 1 and between the two drilling rig crossbeam mechanisms 4. One operating platform walking mechanism 7 is provided at each end of the operating platform mechanism 6. The operating platform walking mechanism 7 is installed on the track beam assembly 2 and moves along the length direction of the track beam assembly 2. Among them, the operating platform mechanism 6 is convenient for the operation of the operator.

[0023] As Figures 1 - 5As shown in FIGS. 7 and 8, the track beam assembly 2 includes a support base 21, a track beam welding assembly 22, a rack 23, a walking track 24, and a limit seat 25. The track beam welding assembly 22 is connected to the crossbeam of the vehicle frame 1 through the support base 21. The track beam welding assembly 22 is respectively provided with a rack 23 and a walking track 24 along its length direction for bearing loads and transmitting power. Limit seats 25 are provided at both ends of the track beam welding assembly 22. The limit seats 25 can limit the crossbeam walking mechanism assembly 3 and are used to limit the walking distance of the drilling rig walking mechanism 5 in the tunnel axis direction. The operating platform walking mechanism 7 includes walking wheels 71, a transmission gear 72, a walking speed reducer 73, an electrical limit contact rod 74, and an audible and visual alarm 75. The transmission gear 72 meshes with the rack 23 of the track beam assembly 2. The walking wheels 71 are installed on the walking track 24 of the track beam assembly 2. The walking speed reducer 73 drives the transmission gear 72 to rotate on the rack 23 of the track beam assembly 2 and drives the walking wheels 71 to move on the walking track 24. The electrical limit contact rods 74 are provided on both longitudinal sides of the operating platform walking mechanism 7 to prevent collision between the operating platform walking mechanism 7 and the crossbeam walking mechanism assembly 3. The audible and visual alarm 75 is connected to the electrical limit contact rod 74. When the electrical limit contact rod 74 contacts the crossbeam walking mechanism assembly 3, the audible and visual alarm 75 will give an alarm.

[0024] As Figure 6 shown, the operating platform mechanism 6 includes an operating platform 61, railings 62, an inclined ladder 63, columns 64, and a climbing ladder 65. Railings 62 are provided on both lateral sides of the operating platform 61. Columns 64 are provided on both longitudinal sides of the operating platform 61. The operating platform mechanism 6 is connected to the operating platform walking mechanism 7 through the columns 64. An inclined ladder 63 is installed on the operating platform 61. Climbing ladders 65 are provided at the lower parts of both longitudinal sides of the operating platform 61. In this embodiment, when the double-arm drilling rig is working, the anchor drilling rig needs to pre-drill the anchor holes in advance, and then switch to the steel pipe shed drilling rig to press the steel pipe shed into the pre-drilled anchor holes. At this time, the operator needs to stand on the operating platform 61 to load the pre-stored steel pipe shed into the steel pipe shed drilling rig; the operator reaches the operating platform 61 from the inner circular surface of the shield through the climbing ladder 65; the inclined ladder 63 is a manually retractable structure and does not need to be released during normal operation. When the maintenance personnel need to perform maintenance and inspection work on the drilling rig crossbeam mechanism 4, the inclined ladder 63 needs to be released and lapped on the drilling rig crossbeam mechanism 4.

[0025] The beneficial technical effects of this embodiment are as follows: The movement of the drilling rig in the tunnel axis direction and the tunnel axis radial direction is realized, which is convenient for drilling, and solves the problems of small drilling angle and low drilling coverage rate of the original drilling rig in the tunnel.

[0026] Although the above embodiments have been described in detail with reference to the accompanying drawings for the concept and embodiments of the purpose of the present utility model, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present utility model without departing from the scope defined by the claims, so they will not be elaborated here one by one.
