Description

Technical Field

[0001] The utility model relates to the technical field of tunnel operation vehicles, in particular to a tunnel operation vehicle which is easy to maintain. Background Art

[0002] A tunnel is an engineering structure buried in the ground. It is a form of human utilization of underground space. The top of the tunnel is usually very high. Therefore, when constructing a tunnel, in order to facilitate the construction on the top of the tunnel, it is usually necessary to use a tunnel work vehicle to lift the construction workers to the top of the tunnel for construction.

[0003] When the existing tunnel working vehicle is in use, in order to ensure the stability of the entire lifting frame, the lifting frame is usually fixed to the vehicle body, which means that when the lifting needs to be inspected and maintained, it is necessary to climb onto the frame to inspect and maintain the lifting frame, and since the space on the top of the frame is very narrow, it is very inconvenient to inspect and maintain the lifting frame. Utility Model Content

[0004] The utility model aims to provide a tunnel operation vehicle which is easy to maintain, so as to solve the problem that the tunnel operation vehicle currently used is inconvenient to inspect and maintain the lifting frame, as mentioned in the above background technology.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 The utility model provides a technical solution: a tunnel operation vehicle that is easy to maintain, comprising: a vehicle body 1 and a guardrail 6, a vehicle frame 2 is installed on the top of the vehicle body 1, a support seat 3 is installed on the top of the vehicle frame 2, a lifting frame 4 is installed on the top of the support seat 3, an operating platform 5 is installed on the top of the lifting frame 4, and the guardrail 6 is installed on the top of the operating platform 5.

[0026] A screw sleeve 7 is installed between the support seat 3 and the groove of the frame 2, and a screw rod 8 is connected through the middle of the screw sleeve 7, and a driving motor 9 is installed on one side of the screw rod 8. Side panels 10 are installed on both sides of the frame 2, and one side of the side panel 10 is connected to a first rotating block 11 through a rotating shaft. A fixed block 12 is installed on the side of the frame 2, and the top of the fixed block 12 is connected to a second rotating block 13 through a rotating shaft. A clamping rod 14 is installed on one side of the second rotating block 13, and a limiting rod 15 that passes through the fixed block 12 is inserted on one side of the clamping rod 14, and a movable spring 16 is installed between the limiting rod 15 and the fixed block 12. A protrusion 23 is installed on one side of the first rotating block 11, and the first rotating block 11 forms a rotating structure with the side panel 10 through the rotating shaft.

[0027] In a specific implementation, when the maintenance of the lifting frame 4 is needed, the limit rod 15 can be pulled toward one side of the fixed block 12 to move the limit rod 15 out of the groove of the clamping rod 14. Without the limit rod 15 limiting the clamping rod 14, the second rotating block 13 can be rotated to rotate through the rotating shaft between the second rotating block 13 and the fixed block 12, and the second rotating block 13 can be separated from the fixed block 12. Without the limit of the second rotating block 13 on the protrusion 23, the second rotating block 13 can be moved. The shaft rotates the first rotating block 11, and the first rotating block 11 is rotated to one side of the side plate 10. At this time, the side plate 10 can be quickly removed from one side of the frame 2, and then the driving motor 9 is started. The driving motor 9 drives the screw rod 8 at the output end to rotate. The rotation of the screw rod 8 will drive the top support seat 3 to slide along the slide groove on the top of the frame 2 through the screw sleeve 7, so that the entire lifting frame 4 can be pushed to one side of the frame 2. At this time, it is convenient for the user to inspect and maintain the lifting frame 4, so that the lifting frame 4 can be used normally;

[0028] On the contrary, the lifting frame 4 can be driven to the middle position of the workshop by the screw rod 8 and the screw sleeve 7, and then the side panel 10 can be installed on one side of the frame 2, and the first rotating block 11 can be rotated to one side of the frame 2 by the rotating shaft, and the protrusion 23 can be docked in the groove of the fixed frame. Since one end of the protrusion 23 is larger, it can be stuck in the groove of the fixed block 12 at this time, and then the second rotating block 13 is rotated to the top of the fixed block 12, and the clamping rod 14 can be docked in the groove on one side of the fixed block 12, and then the limiting rod 15 is released, and the limiting rod 15 will be reset by the movable spring 16 and stuck on one side of the clamping rod 14, so that the second rotating block 13 can be limited, and the side panel 10 can be quickly installed on one side of the frame 2 through the fixed block 12 and the second rotating block 13, so that the bottom of the lifting frame 4 can be protected.

[0029] See also Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 It can be seen that when in use, the side panel 10 can be removed from one side of the frame 2, and then the screw sleeve 7 drives the support seat 3 and the lifting frame 4 to move to one side of the frame 2 through the cooperation of the driving motor 9 and the screw rod 8, so as to facilitate the use and quick inspection and maintenance of the lifting frame 4.

[0030] A rotating rod 17 is connected to one side of the operating platform 5, and a worm 18 is connected to one side of the rotating rod 17 through a bevel gear set. Worm wheels 19 are provided on both sides of the worm 18. A connecting rod 20 is connected to one side of the worm wheel 19. A side of the connecting rod 20 away from the worm wheel 19 is connected to a slider 21 through a rotating shaft. A telescopic plate 22 is provided on one side of the slider 21. The slider 21 forms a sliding structure with the telescopic plate 22 through a sliding groove.

[0031] In specific implementation, the tunnel operation vehicle which is easy to maintain can rotate the rotating rod 17 when it is necessary to place tools. One side of the rotating rod 17 is connected to the worm 18 through a bevel gear set. The bevel gear set is connected by two bevel gears meshing with each other, one bevel gear is connected to the rotating rod 17, and the other bevel gear is connected to the worm 18. With the cooperation of the bevel gear set, the worm 18 can be rotated. Worm wheels 19 are connected to both sides of the worm 18. At this time, the worm 18 will drive the worm wheel 19 to rotate. The worm wheel 19 is connected to the connecting rod 20, and the other side of the connecting rod 20 is connected to the slider 21 through a rotating shaft. The rotation of the worm wheel 19 will drive the connecting rod 20 to rotate, and pull the slider 21 to slide along the slide groove of the telescopic plate 22 with the cooperation of the rotating shaft. At this time, the telescopic plate 22 can be pushed out from one side of the operating platform 5, and some commonly used tools can be placed through the telescopic plate 22 to increase the placement space of the tools.

[0032] See also Figure 1 , Figure 2 and Figure 3 It can be seen that when in use, the rotating rod 17 can be rotated according to the use requirements, and with the cooperation of the worm wheel 19 and the worm 18, the telescopic plate 22 is pushed out from one side of the operating platform 5, and the construction tools can be placed through the telescopic plate 22.

[0033] In summary, the tunnel operation vehicle that is easy to maintain can drive the entire vehicle body 1 to the tunnel that needs to be constructed, and stop the vehicle body 1. Then the construction personnel can climb onto the operating platform 5 through the vehicle frame 2 and control the lifting frame 4 to move upward, so that the construction personnel can be lifted to a suitable height through the lifting frame 4. Then the construction personnel can construct the tunnel. This is the use feature of the tunnel operation vehicle that is easy to maintain.
