DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, a movable shield tunnel construction platform includes a platform 1, a telescopic slot 2 is provided inside the platform 1, a sleeve 3 is slidably provided inside the telescopic slot 2, a first set of rods 4 are fixedly connected to the outer end of the sleeve 3, a wheel bracket 5 is connected to the outer side of the first set of rods 4, a roller 6 is rotatably connected to the wheel bracket 5, and a locking structure 7 for locking the sleeve 3 is provided inside the sleeve 3. By setting the platform 1 as a carrier, it is convenient for workers to construct on the platform 1, and by setting the telescopic slot 2 to provide space for the sliding of the sleeve 3, the sleeve 3 adjusts the distance between the rollers 6 on both sides of the platform 1 by sliding in the telescopic slot 2 to control the telescopic distance of the first set of rods 4, so that whether the platform 1 is walking on the ground or on the track, the roller 6 can effectively abut on the side wall of the tunnel to achieve a stable support effect for the platform 1. By setting the locking structure 7 to lock the sleeve 3, after the roller 6 abuts against the inner wall of the tunnel, the stable support for the platform 1 is achieved.

[0024] A cavity 8 is provided inside the sleeve 3, and the locking structure 7 includes a card slot 7.1 provided on the inner top wall and the inner bottom wall of the cavity 8, and a card member 7.2 inserted between the inner top wall and the inner bottom wall of the cavity 8, and a bolt 9 is rotatably connected to the side of the card member 7.2, and the bolt 9 is threadedly connected to the platform 1. The cavity 8 is provided to provide an installation space for the locking structure 7, and the card member 7.2 is pulled out of the card slot 7.1 by rotating the bolt 9. At this time, the sleeve 3 can slide in the telescopic slot 2, and the roller 6 is abutted against the inner wall surface of the tunnel. After the abutment is completed, the bolt 9 is rotated in the opposite direction to insert the card member 7.2 into the cavity 8. At this time, the sleeve 3 is locked, and the roller 6 will not retract after abutting against the inner wall surface of the tunnel.

[0025] The first rod 4 is connected to the end of the sliding sleeve 3 and the outer sliding sleeve is provided with a second rod 10, the second rod 10 is fixedly connected to the inner wall surface of the platform 1, and the end of the second rod 10 away from the sliding sleeve 3 is fixedly connected to a spring 11. The second rod 10 is provided to provide a basis for the installation of the spring 11, and the spring 11 provides elastic force for adjusting the extension and contraction of the roller 6.

[0026] A disc 12 is fixedly connected to the circumferential surface of one end of the first rod 4 away from the second rod 10, and one end of the spring 11 away from the second rod 10 is fixedly connected to the inner side of the disc 12. By arranging the disc 12 to connect the spring 11, an outward elastic force is provided to the disc 12 during the sliding process of the sliding sleeve 3. After the clamp 7.2 is separated from the sliding sleeve 3, the first rod 4 can be quickly ejected from the telescopic slot 2, and the roller 6 can be supported to always be attached to the inner wall surface of the tunnel during the height adjustment process of the platform 1.

[0027] A gear shaft 13 is rotatably connected in the cavity 8, and teeth 14 meshing with the gear shaft 13 are provided on the inner top wall of the clamp 7.2. A wheel shaft 15 is rotatably connected to the outer end of the first set rod 4. A gear 16 is fixedly sleeved on the outer end of the wheel shaft 15 away from the first set rod 4, and the wheel bracket 5 is fixedly connected to the wheel shaft 15. The clamp 7.2 is pulled out by rotating the bolt 9, and the clamp 7.2 is separated from the clamping slot 7.1, the sliding sleeve 3 is unlocked, and the gear shaft 13 is driven to rotate by the teeth 14, so that the wheel bracket 5 rotates, and the roller 6 is switched from the horizontal state to the longitudinal state.

[0028] The outer end of the first set of rods 4 is fixedly connected with a connecting plate 17, and the wheel axle 15 is passed through the outer surface of the connecting plate 17, and the wheel axle 15 is rotatably connected with the connecting plate 17, and the wheel axle 15 is located above the first set of rods 4. The connecting plate 17 is provided to provide support for the installation of the wheel axle 15. In the process of pulling out the clamp 7.2 and unlocking the sliding sleeve 3, the teeth 14 drive the gear shaft 13 to rotate, and the gear shaft 13 drives the gear 16 to rotate so that the wheel axle 15 rotates, so that the wheel bracket 5 rotates, so that the roller 6 switches from the horizontal state to the longitudinal state, so that the roller 6 can roll in the height direction of the tunnel.

[0029] During the switching process between platform 1 walking on the ground and walking on the track, the height of roller 6 changes, resulting in a change in the width of the tunnel corresponding to roller 6. At this time, roller 6 can be used to move on platform 1 to adjust the distance between rollers 6 in the width direction of platform 1, so that in the above two scenarios, roller 6 can effectively walk close to the inner wall of the tunnel and maintain a stable support effect on platform 1.

[0030] Specifically, the extension and retraction of the roller 6 on the platform 1 can be adjusted in the following manner:

[0031] The first step is to rotate the bolt 9 so that the card 7.2 is separated from the card slot 7.1. At this time, the roller 6 can be adaptively attached to the inner wall of the tunnel under the action of the spring 11. The second step is to rotate the bolt 9 in the opposite direction so that the card 7.2 can be inserted into the card slot 7.1 again to fix the roller 6 in the adjusted position. In the process of the card 7.2 being pulled out from the card slot 7.1, the teeth 14 drive the roller 6 to switch from the horizontal to the vertical direction through the gear shaft 13 and the gear 16, so that when the platform 1 switches between the above two scenarios, the roller 6 rolls along the height direction on the inner wall of the tunnel. In addition, in the process of reinserting the card 7.2 into the card slot 7.1, the teeth 14 drive the roller 6 to switch from the vertical to the horizontal direction through the gear shaft 13 and the gear 16, so that after the roller 6 is locked, the roller 6 can roll on the inner wall of the tunnel along the length direction of the tunnel to maintain a stable support effect on the platform 1.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
