Description

Technical Field

[0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to a climbing and operating device for reinforcing the bottom of a bridge beam. Background Art

[0002] In bridge construction and maintenance projects, construction workers often need to perform various operations at the bottom of the bridge, such as inspection, maintenance, and painting of the bridge structure. Traditional operation methods face many difficulties. On the one hand, since the bottom of the bridge is at a certain height from the ground, providing construction workers with safe and convenient access to and from the bridge becomes a key issue. In the past, long ladders were often built directly on the outside of the bridge. This type of ladder not only occupies a large external space, but also in some complex construction environments, the overly long ladder is very likely to interfere with the surrounding building structures, construction equipment or terrain, affecting the construction progress and even bringing safety hazards. On the other hand, when construction workers are working at the bottom of the bridge, their range of activities is often limited. They need to move frequently to complete work in different parts, but traditional work platforms usually provide limited mobile space and cannot meet the needs of efficient construction. This results in construction workers having to spend a lot of time on relocation, reducing 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 the diverse construction scenarios. How to quickly and conveniently build a construction device that not only meets the construction height requirements, but also provides operators with sufficient moving distance, while ensuring safety and avoiding equipment interference has become an urgent problem to be solved in the field of bridge construction. Summary of the invention

Figure 3, comprising a mobile body 1 for moving the entire device, the top of the mobile body 1 is horizontal, a scissor-type lifting platform 2 is arranged on the top of the mobile body 1, a construction gallery 3 is arranged on the scissor-type lifting platform 2, a long channel 31 extending laterally is arranged along the bottom of the construction gallery 3, and a climbing ladder group is slidably arranged in the long channel 31, such as Figure 4 and Figure 6 As shown, the climbing ladder group includes a plurality of ladder sections 4 connected end to end in sequence, the ladder section 4 includes two ladder frames 41 arranged side by side, a plurality of steps 42 are arranged between the two ladder frames 41, a connecting rod 43 is rotatably provided at one end of the ladder frame 41, and a sliding groove 411 for the connecting rod 43 to slide into is provided at the other end, and a latch 44 and a pin hole 412 for the latch 44 to be inserted are also provided at the end of the ladder frame 41.

[0024] This device is used to quickly build a construction corridor 3 at a suitable height at the bottom of the bridge. The construction corridor 3 is located across the bottom of the bridge, providing operators with more moving distance. The construction corridor 3 moves with the movement of the mobile trolley and the lifting of the scissor-type lifting platform 2. After moving to the construction position, the climbing ladder group located in the long channel 31 at the bottom of the construction corridor 3 can be pulled out. The climbing ladder group consists of a number of mutually hinged ladder sections 4. The pulled out ladder sections 4 and the unpulled ladder sections 4 are connected by the matching of the pins 44 and the pin holes 412 to maintain a uniform straight line splicing. The exit position is the bending position of the climbing ladder group. The connection point of the ladder section 4 at this position is stretched and then rotated, so that the pulled-out ladder section 4 rotates downward and rests on the ground in an inclined state. At this time, a structure to assist operators in climbing is formed. This device is provided with a climbing ladder group that can be adjusted according to the height of the construction corridor 3. This climbing ladder group reasonably utilizes the length of the construction corridor 3 to store the climbing ladder group. Compared with the long ladder directly arranged outside the construction corridor 3, this structure can obtain a shorter climbing structure and will not cause interference with the bridge of the overly long climbing ladder group.

[0025] In a further solution, Figure 2 , Figure 5 and Figure 7As shown, there are two latches 44 and they are slidably arranged along the extension direction of the ladder frame 41. The step 42 is a plate-like structure. A rotating shaft 421 is provided in the middle of both ends of the step 42. The step 42 is rotatably arranged on the side of the ladder frame 41 through the rotating shaft 421. Slide rollers 422 are respectively provided at the two ends of the step 42. A plurality of transverse grooves 441 are arranged on the side of the latch 44. The slide rollers 422 are slidably arranged in the transverse grooves 441. When the ladder section 4 is connected, the latches 44 located in the ladder frame 41 are abutted against each other end to end, and the long channel 31 The end of the ladder group is provided with a fixing portion 5 for fixing the first step 42 at the end of the ladder group, the fixing portion 5 fixes the step 42 so that the step 42 remains horizontal, the fixing portion 5 includes an extension bar 51 arranged at the upper and lower ends of the long channel 31, two fixing columns 52 pass through the extension bar 51, both ends of the fixing column 52 are located on the outside of the two extension bars 51 and are fixed by nuts, and a fixing hole 423 for the fixing column 52 to pass through is provided on the first step 42 at the end of the ladder group, and the fixing holes 423 are respectively located on both sides of the rotating shaft 421.

[0026] In this scheme, a plate-like step 42 is provided for the convenience of construction workers to step on. The plate-like step 42 can be adjusted and fixed by the fixing part 5 after the extended stair section 4, so as to maintain a horizontal state suitable for stepping up and down, that is, two fixing columns 52 pass through the fixing holes 423 on the first step 42 at the end of the ladder group, and the two fixing columns 52 are fixed to the extension strip 51 at the end of the long channel 31 by nuts. The rotation of the first step 42 slides in the slide groove 411 through the sliding roller 422, and drives the movement of the two latches 44 to different distances. The movement of the latches 44 drives the rotation of all the steps 42 in the extended ladder group, so that the steps 42 remain in a horizontal state, and the steps 42 in the extended ladder group remain horizontal, which assists the operator's foot to step up and down and ensures the safety of the construction workers. This structure is easy to adjust and can adapt to stair sections 4 with different inclination angles.

[0027] In a further solution, Figure 2 As shown, the construction corridor 3 is provided with a fixing screw 32, which penetrates into the long channel 31 and is connected to the end of the ladder frame 41 located at the end of the long channel 31. By fixing the fixing screw 32, the extension length of the climbing ladder group can be fixed, and the stability of the climbing ladder group can be improved.

[0028] In a further solution, 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 connection point. The connecting plate 6 is a detachable structure. By fixing the connecting plate 6, it can be ensured that the extended ladder sections 4 are connected to each other to avoid separation.
