Description

Technical Field

[0001] The utility model relates to the technical field of arch frame operation platforms, in particular to an arch frame operation platform for an arch frame trolley. Background Technique

[0002] The arch frame operation platform is a key device used for installing and supporting arch frames in tunnel construction, which provides a safe and stable working surface for construction workers. This kind of platform usually has adjustable functions to adapt to different construction needs and ensure efficient operation in the complex and changeable tunnel environment.

[0003] The patent with the authorized publication number of CN208234502U discloses an arch frame operation platform, which includes a main platform and a flipping platform hinged to the side of the main platform. The flipping platform can be flipped and folded relative to the main platform. In addition, there is a flipping guardrail on the flipping platform that can be flipped and folded relative to the flipping platform, and a connecting piece that flexibly connects the main platform and the flipping platform for hanging the flipping platform. This design effectively expands the operation space of construction workers through the flipping functions of the flipping platform and the flipping guardrail, and at the same time provides a necessary guardrail to enhance safety. However, during the installation of the arch frame, since there are no shielding measures on the tops of both the main platform and the flipping platform, the crushed stones that may fall from the tunnel top pose a safety threat to the staff, and the construction safety cannot be fully ensured.

[0004] Therefore, there is a need for an arch frame operation platform for an arch frame trolley with a protective function. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: An arch operation platform for an arch frame trolley, please refer to Figures 1 - 7, including a support plate 1, a connecting shaft 101, a connecting plate 2, a bottom plate 3, a sliding bar 4, a connecting block 5, a double-shaft motor 6 and a lead screw 7. A connecting shaft 101 is rotatably arranged on the support plate 1. A connecting plate 2 is fixedly connected to the top of the connecting shaft 101. A bottom plate 3 is fixedly connected to the connecting plate 2. Sliding bars 4 are slidably arranged on both the left and right sides of the bottom plate 3. A connecting block 5 is fixedly connected to the bottom of the sliding bar 4. A double-shaft motor 6 is arranged at the bottom of the connecting plate 2 by means of bolt connection. Both output shafts of the double-shaft motor 6 are connected to a lead screw 7 through a coupling. The lead screw 7 is threadedly connected to the connecting block 5. A support plate 8 is arranged on the sliding bar 4 by means of bolt connection. Two support plates 8 jointly set a baffle 9. The support plate 8 slides within the baffle 9. Two support seats I 10 are fixedly connected to the sliding bar 4. A sliding frame 11 is rotatably arranged on the support seats I 10. A support seat II 12 is fixedly connected to the sliding bar 4. A placement frame 13 is rotatably arranged on the support seat II 12. Before installing the arch support, operating tools can be placed in the placement frame 13, which is convenient for the staff to pick up. A lighting lamp 24 is arranged at the bottom of the baffle 9 by means of bolt connection. The lighting lamp 24 can be turned on during operation to illuminate the inside and surrounding of the arch support operation platform, facilitating the work of the staff.

[0027] When an arch support operation platform is needed, first start the arch support trolley and drive it to the designated position in the tunnel. After reaching the designated position, stop the trolley and ensure its stable fixation to prevent accidental movement during construction. Next, turn on the double-shaft motor 6. The two output shafts of the double-shaft motor 6 rotate, driving the lead screw 7 to rotate. As the lead screw 7 rotates, the connecting block 5 moves along the lead screw 7, thereby pushing the sliding bar 4 to expand outwards, increasing the width of the arch support operation platform, so that more staff can be accommodated, improving the work efficiency of arch support installation. As the sliding bar 4 moves outwards, the support plate 8 will also expand accordingly. The support plate 8 and the baffle 9 work together to form a shelter for the top of the arch support operation platform, effectively preventing the gravel that may fall from the tunnel top during operation from hurting the staff and ensuring construction safety.

[0028] Embodiment 2: On the basis of Embodiment 1, please refer to Figure 1 , Figure 2 and Figure 3 , a drive motor 14 is arranged on the support plate 1 by means of bolt connection. The output shaft of the drive motor 14 is connected to a worm 15 through a coupling. A worm gear 16 is fixedly connected to the connecting shaft 101. The worm gear 16 meshes with the worm 15. A protective shell 25 is fixedly connected to the support plate 1. The drive motor 14, the worm 15 and the worm gear 16 are all located inside the protective shell 25, thereby protecting the drive motor 14, the worm 15 and the worm gear 16 and preventing foreign objects from winding around the worm 15 and the worm gear 16 and affecting the adjustment of the angle of the arch support operation platform.

[0029] When it is necessary to adjust the angle of the arch frame working platform, the driving motor 14 is turned on. The output shaft of the driving motor 14 rotates to drive the worm 15 to rotate. Under the meshing action of the worm gear 16 and the worm 15, the worm gear 16 rotates accordingly and drives the connecting shaft 101 to rotate, adjusting the angle of the connecting plate 2, thereby changing the angle of the arch frame working platform to meet the requirements of different working environments and tasks.

[0030] Please refer to Figures 5 - 9 , sliding plates 17 are fixedly connected to both the left and right sides of the bottom plate 3. A number of card slots 18 are formed in the sliding plates 17. A support shell 22 is fixedly connected to the sliding bar 4. Two guide rods 20 are fixedly connected to the support shell 22. A clamping plate 19 is slidably arranged on the two guide rods 20 together. The clamping plate 19 is snapped into the card slot 18. A return spring 21 is sleeved on the guide rod 20. The two ends of the return spring 21 are respectively connected to the support shell 22 and the clamping plate 19. An electromagnet 23 is arranged inside the support shell 22.

[0031] When it is necessary to widen the arch frame working platform, the electromagnet 23 is energized to generate suction, adsorbing the clamping plate 19 to move outwards and disengage from the card slot 18, thereby releasing the limit on the sliding bar 4. At this time, the return spring 21 is compressed accordingly. Then, the double-shaft motor 6 is turned on to widen the arch frame working platform. After the operation is completed, the output shaft of the double-shaft motor 6 is controlled to reverse to restore the arch frame working platform. Subsequently, the electromagnet 23 is powered off, and the return spring 21 immediately returns to its original state, pushing the clamping plate 19 to move inwards and re-engage with the card slot 18, thereby limiting the sliding bar 4 again to prevent it from moving.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
