Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of bridge construction equipment, and particularly relates to a climbing and working device for bridge beam bottom reinforcement. BACKGROUND

[0002] In bridge construction and maintenance engineering, construction personnel often need to perform various types of work at the bottom of the bridge, such as bridge structure detection, repair, painting, and the like. The traditional working method faces many problems. On the one hand, since the bridge bottom is a certain height from the ground, providing a safe and convenient access for the construction personnel becomes a key problem. In the past, a long ladder was often directly built on the outside of the bridge. Such a long ladder not only occupies a large external space, but also in some complex construction environments, the excessively long ladder is prone to interfere with the surrounding building structures, construction equipment, or topography, affecting the construction progress, and even causing safety hazards. On the other hand, when the construction personnel work at the bottom of the bridge, their activity range is often limited. They need to frequently move positions to complete work at different parts, but the traditional working platform usually provides limited moving space, which cannot meet the needs of efficient construction. This results in the construction personnel having to spend a lot of time on position transfer, reducing the overall construction efficiency.

[0003] With the development of bridge construction technology and the continuous improvement of construction quality and safety requirements, the existing simple construction auxiliary equipment has been difficult to adapt to diversified construction scenes. How to quickly and conveniently build a construction device that not only meets the construction height requirements, but also provides sufficient moving distance for the operator, while ensuring safety and avoiding equipment interference, has become a problem to be solved in the field of bridge construction.

DETAILED DESCRIPTION

[0023] With reference to Figure 1 , the present application discloses a climbing and working device for bridge deck reinforcement, which is used for lifting on the bridge deck, assisting the worker in climbing and working, and with reference to Figure 3, including a mobile trolley 1 for moving the entire device, a scissor lift platform 2 provided on top of the mobile trolley 1, a construction gallery 3 provided on the scissor lift platform 2, a long strip passage 31 extending transversely along the bottom of the construction gallery 3, and a climbing ladder set slidingly provided in the long strip passage 31, as shown in Figure 4 and Figure 6 , the climbing ladder set comprises a plurality of ladder segments 4 connected end to end, each ladder segment 4 comprises two ladder frames 41 arranged side by side, a plurality of steps 42 arranged between the two ladder frames 41, a connecting rod 43 rotatably provided at one end of the ladder frame 41, and a sliding groove 411 provided at the other end of the ladder frame 41 for the connecting rod 43 to slide into, and a latch 44 provided at the end of the ladder frame 41 and a pin hole 412 for the latch 44 to insert into.

[0024] This device is used to quickly build the construction gallery 3 at an appropriate height on the bottom of the bridge, the construction gallery 3 spans the side of the bridge to provide more moving distance for the operator, and the construction gallery 3 moves with the mobile trolley and the lifting of the scissor lift platform 2, and after moving to the construction position, the climbing ladder set in the long strip passage 31 at the bottom of the construction gallery 3 can be pulled out, the climbing ladder set is composed of a plurality of ladder segments 4 connected to each other, the pulled-out ladder segments 4 and the not-pulled-out ladder segments 4 are connected through the cooperation of the latch 44 and the pin hole 412 to maintain the straight-line splicing, at the exit position of the long strip passage 31, the bending position of the climbing ladder set, the connection point of the ladder segments 4 at this position is pulled out and rotated, so that the pulled-out ladder segments 4 rotate downward and rest on the ground in an inclined state, thus forming a structure for assisting the operator to climb, this device sets the climbing ladder set which can be adjusted according to the height of the construction gallery 3, this climbing ladder set reasonably utilizes the length of the construction gallery 3 to store the climbing ladder set, compared with the long ladder directly provided outside the construction gallery 3, this structure can obtain a relatively short climbing structure and will not cause the interference of the long climbing ladder set with the bridge.

[0025] In a further scheme, as shown in Figure 2 , Figure 5 and Figure 7As shown, there are two pins 44 that slide along the extension direction of the ladder frame 41. The ladder step 42 is a plate-like structure. A pivot 421 is provided at the middle of both ends of the ladder step 42. The ladder step 42 is rotatably mounted on the side of the ladder frame 41 via the pivot 421. Sliding rollers 422 are provided at both ends of the ladder step 42. Several transverse grooves 441 are arranged on the side of the pin 44, and the sliding rollers 422 slide within the transverse grooves 441. When the ladder segments 4 are connected, the pins 44 located within the ladder frame 41 abut against each other. The elongated channel 31... The end of the ladder assembly is provided with a fixing part 5 for fixing the first step 42 of the ladder assembly. The fixing part 5 fixes the step 42 to keep the step 42 horizontal. The fixing part 5 includes an extension strip 51 set at the upper and lower ends of the long channel 31. Two fixing posts 52 pass through the extension strip 51. The two ends of the fixing posts 52 are located outside the two extension strips 51 and are fixed by nuts. Fixing holes 423 are opened on the first step 42 of the ladder assembly for the fixing posts 52 to pass through. The fixing holes 423 are respectively located on both sides of the rotating shaft 421.

[0026] In this design, a plate-shaped ladder step 42 is provided for easy footing by construction workers. The plate-shaped ladder step 42 can be adjusted and fixed by a fixing part 5 after the extended ladder section 4, so as to keep it in a horizontal state suitable for footing. Specifically, two fixing posts 52 pass through the fixing holes 423 on the first ladder step 42 at the end of the ladder group. The two fixing posts 52 are fixed to the extension strip 51 at the end of the long channel 31 by nuts. The rotation of the first ladder step 42 causes the sliding roller 422 to slide in the sliding groove 411, which drives the two pins 44 to move at different distances. The movement of the pins 44 drives the rotation of all the ladder steps 42 in the extended ladder group, keeping the ladder steps 42 in a horizontal state. Keeping the ladder steps 42 in the extended ladder group horizontal assists the operator in stepping up and down, ensuring the safety of construction workers. This structure is easy to adjust and adapts to ladder sections 4 with different inclination angles.

[0027] In further proposals, such as Figure 2 As shown, the construction corridor 3 is equipped with fixing screws 32, which pass through the long passage 31 and connect to the end of the ladder frame 41 located at the end of the long passage 31. By fixing the screws 32, the extension length of the climbing ladder assembly can be fixed, thereby improving the stability of the climbing ladder assembly.

[0028] In further proposals, such as Figure 4 and Figure 5 As shown, it also includes a connecting plate 6, which is fixedly connected to the inner sides of the two ladder frames 41 at the joint. The connecting plate 6 is a detachable structure. By fixing the connecting plate 6, it can be ensured that the extended ladder segments 4 are connected to each other and prevent separation.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
