DETAILED DESCRIPTION

[0018] The utility model will be further described through the specific implementation.

[0019] Referring to Figures 1 to 5 The adjusting passageway connecting the crawling ladder and the capped beam construction platform comprises a connection mechanism 1, steps 2, a rotating mechanism 3 and an angle adjusting mechanism 4.

[0020] The connection mechanism 1 is provided with two, is connected in parallel between the crawling ladder 5 and the capped beam construction platform 6, and comprises an upper rotating rod 11, a lower rotating rod 12 and a connecting rod 13; the upper rotating rod 11 is rotatable on the crawling ladder 5; the lower rotating rod 12 is rotatably arranged on the capped beam construction platform 6 and corresponds to the upper rotating rod 11; and the connecting rod 13 is connected between the upper rotating rod 11 and the lower rotating rod 12. The connection mechanism 1 further comprises a fixing assembly 14 connected between the connecting rod 13 and the upper rotating rod 11 or the lower rotating rod 12, and the fixing assembly 14 comprises a mounting seat 141 arranged at the end of the upper rotating rod 11, the lower rotating rod 12 and the connecting rod 13, a fixing screw 142 penetrating through the mounting seat 141 and a fixing nut 143 cooperating with the fixing screw 142 to fix the two mounting seats 141. Specifically, the passageway guardrail 15 is arranged on the connection mechanism 1, and the two ends of the passageway guardrail 15 are fixed on the upper rotating rod 11 and the lower rotating rod 12 respectively; since the connecting rod 13 is only connected with the two ends of the upper rotating rod 11 and the lower rotating rod 12, the connection mode is less reliable than the connection mode of the upper rotating rod 11 or the lower rotating rod 12 with the crawling ladder 5 or the capped beam construction platform 6, so the guardrail is not connected with the connecting rod 13, thereby reducing the influence of external force on the connecting rod 13.

[0021] The steps 2 are provided with a plurality of, are evenly arranged between the two connection mechanisms 1. The steps 2 are L-shaped, comprising a supporting part 21 and a blocking part 22 connected perpendicularly to each other, the connection position of the steps 2 and the rotating shaft is located at the connection position of the supporting part 21 and the blocking part 22, the bottom surface of the supporting part 21 is supported on the supporting column 43 for being stepped on by the construction personnel, the blocking part 22 extends vertically downward from the end of the supporting part 21 for preventing the construction personnel from stepping empty, the supporting column 43 is inserted into different positioning holes 42 according to the angle of rotation of the connection mechanism 1, so that the supporting part 21 of the steps 2 is always in a relatively stable position, facilitating the construction personnel to climb.

[0022] The rotating mechanism 3 is arranged on the ladder 5 and the bent cap construction platform 6 and connected with the upper rotating rod 11 and the lower rotating rod 12 respectively.

The upper rotating rod 11 is arranged on the rotating seat 31 and rotates around the second rotating shaft 35. The fixing seat 32 is arranged on the bent cap construction platform 6, and the lower rotating rod 12 is rotatably arranged on the fixing seat 32. The limiting groove 33 extends in the circumferential direction of the second rotating shaft 35. The limiting rod 34 is arranged on the rotating seat 31 and opposite to the limiting groove 33, and can be inserted into the limiting groove 33 to limit the rotating range of the upper rotating rod 11. During installation, the upper rotating rod 11 is first installed on the rotating seat 31, then the connecting rod 13 and the lower rotating rod 12 are sequentially installed, and then the lower rotating rod 12 is supported at the end of the bent cap construction platform 6 by rotating the upper rotating rod 11, and then the lower rotating rod 12 is fixed on the fixing seat 32. The installation is simple and convenient, and the connecting mechanism 1 can be quickly adjusted and installed through the rotating mechanism 3.

The supporting column 43 can pass through different positioning holes 42 and contact the bottom surface of the footboard 2, thereby supporting the footboard 2 and adjusting the angle of the footboard 2. Compared with the fixed channel, the angle change of the connecting mechanism 1 causes the footboard 2 to tilt, which makes it difficult for the construction personnel to climb. The application always keeps the footboard 2 horizontal, which is more conducive to the walking and climbing of the construction personnel, and the structure is simple. The installation and correction of the angle of the footboard 2 can be quickly performed after the rotating adjustment of the connecting mechanism 1 is completed. Specifically, the positioning holes 42 are arranged on the upper rotating rod 11, the lower rotating rod 12 and the connecting rod 13. The spacing of the positioning holes 42 on the upper rotating rod 11 or the lower rotating rod 12 is the same as the spacing of the positioning holes 42 on the connecting rod 13, so that the footboard 2 maintains the same spacing. Further, when the connecting mechanism 1 is at an angle of 45°, 2-3 positioning holes 42 are arranged on the upper and lower sides of the supporting part 21 of the footboard 2 respectively, and the angle between the adjacent two positioning holes 42 is 5°-10°.

[0024] In the installation, the upper rotating rod 11, the connecting rod 13 and the lower rotating rod 12 are sequentially connected and fixed through the fixing mechanism, and are transported to the ladder 5, the upper rotating rod 11 is installed on the rotating seat 31, the lower rotating rod 12 is made to be placed on the bent cap construction platform 6 by rotating the connecting mechanism 1, then the front and back positions of the fixing seat 32 are adjusted for fixing the lower rotating rod 12, then the position of the supporting column 43 is adjusted according to the rotating angle to keep the step plate 2 horizontal, finally the channel guard 15 is installed to complete the installation of the channel. According to the cover degree of the ladder 5 and the bent cap construction platform 6, the angle of the upper rotating rod 11 and the lower rotating rod 12 can be adjusted, so that they are just connected between the two, adapt to different height differences, improve the use scene, have high universality, meanwhile, the supporting column 43 can be inserted into different positioning holes 42 according to the rotating angle of the connecting mechanism 1, and the step plate 2 is supported on the supporting column 43, so that the step plate 2 is always in a relatively horizontal position when the connecting mechanism 1 rotates, which is convenient for the construction personnel to climb, has high practicability.

[0025] The above is only a preferred embodiment of the present application, and therefore cannot limit the scope of the present application, that is, equivalent changes and modifications made according to the patent application scope and the content of the specification should still be within the scope of the present application.
