Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold for tunnel maintenance. Background Art

[0002] Tunnel maintenance often requires high-altitude operations, such as inspecting the tunnel top structure, repairing cracks, and cleaning dust. The setting of scaffolding can provide construction workers with a stable working platform, reducing the risk of falling from heights and improving work safety.

[0003] After searching, the announcement number CN216109607U discloses a scaffold for railway tunnel maintenance. When using the scaffold, the scaffold is first moved to the desired position, and the knob is turned to make its stud drive the gear to rotate, thereby driving the rotating rod and the hinged rod to rotate, and the hinged rod drives the connecting rod to rotate. Through the coordinated use of rollers, the stairs are effectively unfolded, which makes it easy for workers to climb onto the frame. It is simple to operate and convenient to use.

[0004] However, when the above scaffold is in use, the scaffold is fixed as a whole and cannot be quickly disassembled, resulting in the scaffold taking up more space when being moved, transported and stored, reducing the space utilization rate around the scaffold and reducing the use effect of the scaffold.

[0009] Connecting plates are fixedly provided at both ends of the adjacent side of the first side plate and the second side plate, and a plurality of hinged bearing plates are provided between two laterally adjacent connecting plates, and the bearing plates are hingedly matched with the connecting plates;

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The embodiment of the utility model discloses a scaffold for tunnel maintenance.

[0027] The utility model provides Figure 1-3 The tunnel maintenance scaffold shown includes a first side panel 1 and a second side panel 2. A climbing ladder 15 is fixedly provided on the outer wall of the second side panel 2. Two symmetrically arranged drive columns 3 are rotatably provided on both sides of the outer wall of the first side panel 1. A slide groove 4 is provided on both sides of the second side panel 2. Two symmetrically arranged sliding columns 5 are slidably provided in the two slide grooves 4. The cross-sections of the drive columns 3 and the sliding columns 5 are both T-shaped. A connecting plate 6 is fixedly provided between two adjacent staggered drive columns 3 and sliding columns 5.

[0028] Connecting plates 7 are fixedly provided at both ends of the adjacent sides of the first side plate 1 and the second side plate 2 . A plurality of hinged supporting plates 8 are provided between two laterally adjacent connecting plates 7 . The supporting plates 8 are hingedly matched with the connecting plates 7 .

[0029] When the scaffolding is not in use, the first side panel 1 and the second side panel 2 are close to each other. At this time, the multiple supporting plates 8 are folded and arranged, and the angle between the two adjacent connecting plates 6 is the largest. At this time, the space occupied by the scaffolding is small and the space utilization rate is high. When the scaffolding needs to be used, the multiple driving columns 3 on the outside of the first side panel 1 can be rotated so that the two adjacent driving columns 3 rotate in opposite directions. At this time, under the sliding cooperation of the sliding column 5 and the slide groove 4, the angle between the two adjacent connecting plates 6 is reduced, which can quickly separate the first side panel 1 and the second side panel 2. At the same time, the multiple supporting plates 8 are unfolded and gradually transformed into a horizontal state. At this time, the scaffolding is completed. The operator can move to the top of the scaffolding by climbing the escalator 15 and quickly maintain the interior of the tunnel with the support of multiple supporting plates 8.

[0030] In order to enable the first side panel 1 and the second side panel 2 to be separated quickly, and at the same time, the position of the supporting panels 8 can be stably supported after the multiple supporting panels 8 are unfolded, such as Figure 1-2As shown, a driving opening and closing mechanism is provided between two adjacent driving columns 3, and the driving opening and closing mechanism includes two symmetrically arranged fixed plates 9, and the two fixed plates 9 are fixedly arranged on the side walls of the first side plate 1. A worm 10 is rotatably provided inside the two fixed plates 9, and the two worms 10 are fixedly connected. The thread directions of the rod walls of the two adjacent worms 10 are opposite. The outer wall of the driving column 3 is fixedly sleeved with a worm gear 11, and the worm gear 11 is matched with the worm 10. A rotating block 12 is fixedly provided at the bottom of the worm 10, and a through hole is provided at the lower end of the first side plate 1. The lower ends of the two worms 10 are fixedly sleeved with a synchronous wheel 13, and a transmission sleeve between the two synchronous wheels 13 is provided with a synchronous belt 14, and the synchronous belt 14 is provided in the through hole.

[0031] When the scaffolding needs to be unfolded, the rotating block 12 can be rotated. At this time, the two worms 10 on the same side rotate simultaneously under the support of the fixed plate 9, and the multiple worms 10 on both sides of the first side plate 2 can rotate simultaneously under the transmission of the synchronous wheel 13 and the synchronous belt 14. At this time, with the cooperation of the worm 10 and the worm wheel 11, the driving column 3 can be driven to rotate. At the same time, since the thread directions of the rod walls of the two adjacent worms 10 are opposite, the rotation directions of the two adjacent driving columns 4 are opposite, so that the two adjacent connecting plates 6 can be staggered and rotated to complete the reduction of the angle. At this time, under the push of the connecting plate 6, the second side plate 2 can move away from the first side plate 1 to complete the unfolding of the scaffolding. Since the worm 10 and the worm wheel 11 have a self-locking function after stopping rotation, the multiple bearing plates 8 can maintain a stable unfolding state while the scaffolding is unfolded, which can provide stable support for the operator and ensure the stability of the scaffolding.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
