Description

Technical Field

[0001] This utility model relates to the field of safety passage technology, specifically to a double-span bridge deck safety passage. Background Technology

[0002] During the construction of a double-span bridge, safety passages play a crucial role in ensuring the safety of construction workers. However, traditional double-span bridge safety passages have certain limitations in practical applications.

[0003] Existing safety passages have fixed dimensions before being put into use. Their width, length, and height are difficult to adjust flexibly according to the actual needs of the construction site and the specific requirements of different construction workers. These fixed-size safety passages often fail to achieve optimal safety assurance when faced with different specifications of double-span bridge decks and variations in the number of construction workers and their work methods.

[0004] Therefore, we propose a double-span bridge deck safety passage. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings and provide a safe passage across a double-span bridge deck.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model is achieved using the following technical solution: a safety passage across a double-span bridge deck, including a passage mechanism for pedestrians to cross the bridge deck, including a passage step one and a passage step two disposed below the passage step one. The passage step two is provided with a connecting component for connecting the passage step one. The passage mechanism is placed above the gap between the two bridge decks, and construction workers can cross the double-span bridge deck by stepping on the passage step one and the passage step two.

[0008] The connecting assembly includes a sliding groove on both sides of the second passage pedal and a threaded post fixed to the bottom side of the first passage pedal and slidably inserted in the sliding groove. The threaded post passes through the sliding groove and is provided with a limiting nut for abutting the second passage pedal and the first passage pedal. The overall length of the passage mechanism can be adjusted by the operation of the connecting assembly.

[0009] The positioning component includes multiple slots formed on the bottom side of the first passage pedal, and a locking block fixed on the top of the second passage pedal that mates with the adjacent slots. The relative positions of the first passage pedal and the second passage pedal can be defined by the sliding engagement of the slots and the locking blocks.

[0010] As a further improvement to the above solution, the diameter of the limiting nut is greater than the width of the groove. By using a limiting nut with a diameter greater than the width of the groove, the limiting nut can be prevented from passing through the groove.

[0011] As a further improvement to the above solution, protective plates for warning construction workers are fixed on both sides above the first and second passage steps. The protective plates on the first and second passage steps are staggered. Warning signs are affixed to the protective plates. The protective plates can be used to warn construction workers on the bridge.

[0012] As a further improvement to the above solution, each of the two passage pedals, one at a distance from the other, is fixed with a side plate. The side plate is provided with an adjustment component for adjusting the height of the side plate, and the two passage pedals can be supported by the side plate.

[0013] As a further improvement to the above solution, the adjustment assembly includes a base plate fixed to the bottom of the side plate and casters fixed to the four corners of the bottom of the base plate. The top side of the base plate is fixed with a step block fixed to the side plate. The base plate has multiple sliding grooves, and a support block for supporting the base plate is slidably inserted inside the sliding groove. By rotating the casters on the bottom side of the base plate, the passage mechanism can be moved. By operating the adjustment assembly, the corresponding heights of passage step one and passage step two can be adjusted.

[0014] As a further improvement to the above solution, a connecting block is slidably connected inside the pedal block, and the top of the support block is fixed on the connecting block. Above the connecting block, there is a threaded post with opposite thread directions at both ends. The outer walls of the threaded post are threaded with drive blocks that slide inside the pedal block. Fixed blocks are fixed on both sides of the top side of the connecting block. The outer side of the fixed block is hinged with a transmission block, the other end of which is hinged to the adjacent drive block. Through the cooperation of the threaded post and the drive block, the drive block can be moved, the transmission block can be deflected, the fixed block can be moved vertically, and the support block can be moved vertically.

[0015] As a further improvement to the above solution, one end of the threaded post II is rotatably connected to the inner side of the adjacent foot block, and the other end of the threaded post II passes through the adjacent side plate and is fixed with a handle for driving the threaded post II to rotate. Rotating the handle can drive the threaded post II to rotate.

[0016] As a further improvement to the above solution, the handle is threaded with a bolt, and the inner side of the side plate is provided with multiple threaded grooves that mate with the bolt threads. Through the cooperation of the bolt and the threaded grooves, the handle and the threaded post can be locked. When it is necessary to rotate the handle, the bolt can be rotated to drive the bolt out of the threaded groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model allows construction workers to easily walk across a double-span bridge deck. The overall length of the passage mechanism can be adaptively adjusted according to the width of the gap between the two bridge decks. The placement of the passage mechanism can be flexibly adjusted according to installation requirements. It is easy to use and the height of the passage mechanism can be adjusted according to the length of the steel bars in the gap between the two bridge decks. It has a wide range of applications.

[0019] In summary, this utility model has a reasonable structure, which facilitates construction workers to walk across the double-span bridge deck. It allows for adaptive adjustment of the overall length and height of the passage mechanism and flexible control of its placement position, making it highly flexible and easy to use.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1:

[0030] Combination Figure 1 , Figure 2 and Figure 6 This embodiment provides a double-span bridge deck cross-span safety passage, including a passage mechanism for pedestrians to cross the bridge deck, including a passage step 1 and a passage step 2 disposed below the passage step 1, with a connecting component on the passage step 2 for connecting to the passage step 1.

[0031] The connecting assembly includes a slide groove 9 opened on both sides of the passage pedal 2 and a threaded post 10 fixed on the bottom side of the passage pedal 1 and slidably inserted in the slide groove 9. The threaded post 10 passes through the slide groove 9 and is provided with a limiting nut 11 for abutting the passage pedal 2 and the passage pedal 1.

[0032] The positioning component includes multiple slots 12 formed on the bottom side of the passage pedal 1, and a locking block 13 fixed on the top of the passage pedal 2 to cooperate with the adjacent slots 12.

[0033] The implementation principle of a cross-span safety passage on a double-span bridge deck in this application embodiment is as follows: The passage mechanism is placed above the gap between the two bridge decks. Construction workers can walk across the double-span bridge deck by stepping on passage tread 1 and passage tread 2. When construction workers need to adjust the overall length of the passage mechanism during use, they can rotate the limiting nut 11, causing it to shift. When the limiting nut 11 separates from the bottom side of passage tread 2, they can pull passage tread 1 or passage tread 2, causing passage tread 1 to shift vertically upwards or passage tread 2 to shift vertically downwards. When the locking block 1 on passage tread 2... 3. After disengaging from the slot 12, the passage pedal 1 or passage pedal 2 can be pulled laterally to move the passage pedal 1 or passage pedal 2 laterally. At this time, the overall length of the passage mechanism can be adjusted. After the overall length of the passage mechanism is adjusted, the passage pedal 1 or passage pedal 2 can be pulled to move the passage pedal 1 vertically downward or the passage pedal 2 vertically upward. When the locking block 13 on the passage pedal 2 enters the adjacent slot 12, the limiting nut 11 is rotated to move the limiting nut 11. When the limiting nut 11 contacts the bottom side of the passage pedal 2, the overall length of the passage mechanism is fixed.

[0034] The diameter of the limiting nut 11 is greater than the width of the slide groove 9. By using the limiting nut 11 with a diameter greater than the width of the slide groove 9, the limiting nut 11 can be prevented from passing through the slide groove 9.

[0035] Protective plates 7 are fixed on both sides above the passage tread 1 and passage tread 2. The protective plates 7 on passage tread 1 and passage tread 2 are staggered. Warning signs are affixed to the protective plates 7, which can be used to warn construction workers on the bridge.

[0036] Example 2:

[0037] Combination Figure 3 , Figure 4 and Figure 5This embodiment, based on embodiment 1, further improves upon the following: Side plates 3 are fixed to the ends of both the first and second passage treads 1 and 2, which are located away from each other. The side plates 3 are equipped with adjustment components for adjusting their height. These components include a base plate 4 fixed to the bottom of the side plate 3 and casters 6 fixed to the four corners of the bottom of the base plate 4. The casters 6 are equipped with limiting mechanisms. A foot block 5 is fixed to the top of the base plate 4 and is also fixed to the side plate 3. The base plate 4 has multiple sliding grooves, and support blocks 15 for supporting the base plate 4 are slidably inserted into the sliding grooves. By pushing the side plate 3, the height of the bottom plate 4 is adjusted via the casters 6. The rotation of wheel 6 can drive the passage mechanism to move. At this time, the corresponding position of the passage mechanism can be adjusted. When the passage mechanism needs to be used, the support block 15 can be pulled to move the support block 15 vertically downward. When the support block 15 contacts the bridge deck and supports the bottom plate 4, the universal wheel 6 on the bottom side of the bottom plate 4 is separated from the bridge deck. At this time, the construction personnel can step on the step block 5 to move to the top side of the passage step 1 and passage step 2. By adjusting the corresponding position of the support block 15, the corresponding height of the bottom plate 4, side plate 3, passage step 1 and passage step 2 can be adjusted.

[0038] The pedal 5 is internally slidably connected to a connecting block 14. The top of the support block 15 is fixed to the connecting block 14. Above the connecting block 14 is a threaded post 16 with opposite thread directions at both ends. The outer walls of the threaded post 16 are threaded with drive blocks 17 that slide inside the pedal 5. Fixed blocks 18 are fixed on both sides of the top side of the connecting block 14. The outer side of the fixed block 18 is hinged to a transmission block 19 with its other end hinged to the adjacent drive block 17. By rotating the threaded post 16, the drive block 17 can be moved by the cooperation of the threaded post 16 and the drive block 17, which in turn causes the transmission block 19 to deflect, the fixed block 18 to move vertically, and the support block 15 to move vertically.

[0039] One end of the threaded post 16 is rotatably connected to the inner side of the adjacent foot block 5, and the other end of the threaded post 16 passes through the adjacent side plate 3 and is fixed with a handle 20 for driving the threaded post 16 to rotate. Rotating the handle 20 can drive the threaded post 16 to rotate.

[0040] The handle 20 is threaded with a bolt 21. The inner side of the side plate 3 has multiple threaded grooves 8 that are threaded to the bolt 21. The handle 20 and the threaded post 16 can be locked by the cooperation of the bolt 21 and the threaded grooves 8. When the handle 20 needs to be turned, the bolt 21 can be turned to drive the bolt 21 out of the threaded grooves 8.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
