[0024] Reference Figure 1 and Figure 2The utility model discloses a bridge reconstruction work platform, including two guide beams 100, four ladder cages 300, two trusses 500 and a plurality of scaffolding boards 700. The length direction of the guide beams 100 is the same as the length direction of the beam body 200. The two guide beams 100 are used to be arranged on the left and right sides of the beam body 200; the four ladder cages 300 are distributed in a rectangular shape, wherein two ladder cages 300 are connected to one of the guide beams 100 through two first lifting mechanisms 400, and the other two ladder cages 300 are connected to the other guide beam 100 through the other two first lifting mechanisms 400. The first lifting mechanisms 400 can drive the ladder cages 300 to rise and fall; both ends of the two trusses 500 are provided with limit Channel, the length direction of the truss 500 is parallel to the left-right direction, one truss 500 is sleeved on two ladder cage frames 300 distributed on the left and right through two limiting channels, and the two ends of one truss 500 are respectively connected to the two ladder cage frames 300 distributed on the left and right through two second lifting mechanisms 600, another truss 500 is sleeved on the other two ladder cage frames 300 distributed on the left and right through two limiting channels, and the two ends of another truss 500 are respectively connected to the other two ladder cage frames 300 distributed on the left and right through two second lifting mechanisms 600, and the second lifting mechanisms 600 can drive the truss 500 to rise and fall; multiple scaffolding boards 700 are laid on the two trusses 500 to form an operating platform.

[0025] The first lifting mechanism 400 can adjust the height of the ladder cage 300, and the second lifting mechanism 600 can adjust the height of the truss 500 and the scaffolding 700. After the ladder cage 300, the truss 500 and the scaffolding 700 are installed on the ground, the ladder cage 300 and the operating platform can be lifted to the height of each construction point of the beam body 200. The operating platform provides space for construction personnel and various construction tools, making it convenient for construction personnel to carry out construction at each construction point of the beam body 200.

[0026] Since the length direction of the guide beam 100 is the same as that of the beam body 200, the two guide beams 100 are respectively arranged on the left and right sides of the beam body 200, and the guide beam 100 can be stably placed on the beam body 200. Even during the partial demolition of the bridge, the guide beam 100 can still stably hold the ladder cage 300, the truss 500 and the scaffolding 700, and the bridge reconstruction work platform can still provide a construction work surface for the construction of the bridge surface reinforcement.

[0027] The truss 500 is sleeved on two ladder cage frames 300 distributed on the left and right through two limiting channels. The limiting channels can limit the truss 500 on the ladder cage frames 300 to avoid excessive horizontal deviation of the truss 500 on the ladder cage frames 300.

[0028] The scaffolding plank 700 can be connected by connecting the two ends of the scaffolding plank 700 to two trusses 500 respectively, or by setting multiple support rods between the two trusses 500, interlacing the multiple support rods and connecting the two trusses 500 together, and then laying multiple scaffolding planks 700 slowly on the multiple support rods.

[0029] In some of the embodiments, the guide beam 100 includes a plurality of first Bailey beams connected in sequence. The first Bailey beams have a simple structure, are easy to assemble, and have a strong bearing capacity.

[0030] The length of the plurality of first Bailey beams connected in series should be long enough so that the contact area between the guide beam 100 and the beam body 200 is large enough so that the guide beam 100 can be sufficiently supported.

[0031] In some of the embodiments, the ladder cage 300 is connected to the guide beam 100 through a rope group, and the rope group firmly drops the ladder cage 300 on the guide beam 100. The rope group and the first lifting mechanism 400 can play a role of double traction of the ladder cage 300, thereby improving the safety of the ladder cage 300.

[0032] According to the installation position requirements of the ladder cage 300, one section of the rope group and the first lifting mechanism 400 are connected to the corresponding position of the guide beam 100, and then the hook of the first lifting mechanism 400 is connected to the upper end of the ladder cage 300. The first lifting mechanism 400 lifts the ladder cage 300 to the construction point, and then the other section of the rope group is connected to the upper end of the ladder cage 300.

[0033] After the second lifting mechanism 600 is connected to the corresponding position of the guide beam 100 or the ladder cage 300, the hook of the second lifting mechanism 600 is then connected to the upper end of the truss 500. After the second lifting mechanism 600 lifts the truss 500 to the construction site, the ladder cage 300 and the truss 500 can be connected together through other rope groups to improve the safety of the truss 500 and the operating platform.

[0034] In some of the embodiments, the first lifting mechanism 400 and the second lifting mechanism 600 are both electric hoists, which are common components, easy to set up and use, and have low cost.

[0035] In some of the embodiments, a ladder structure is provided in the ladder cage 300, and the ladder structure is used for construction workers to pass through. The construction workers can move from the beam body 200 to the operating platform through the ladder structure.

[0036] In some of the embodiments, the ladder cage 300 includes a plurality of second Bailey beams connected in sequence. The second Bailey beams have a simple structure, are easy to assemble, and have a strong bearing capacity.

[0037] In some of the embodiments, the truss 500 includes a plurality of third Bailey beams connected in sequence. The third Bailey beams have a simple structure, are easy to assemble, and have a strong bearing capacity.

[0038] Of course, the ladder cage 300 and the truss 500 may also be other forms of hollow beam structures. The guide beam 100, the ladder cage 300 and the truss 500 are made of square steel.

[0039] In some of the embodiments, the bridge reconstruction work platform also includes a lifting trolley 800 and two guide rails. The two guide rails are respectively arranged on two guide beams 100, and the guide rails and the guide beams 100 have the same length direction. The lifting trolley 800 is straddled on the two guide rails. The lifting trolley 800 is moved on the two guide beams 100 through the two guide rails, so that the lifting trolley 800 is located on different sections on the beam body 200.

[0040] The hoisting crane 800 is used to hoist the ladder cage 300, the truss 500 and the scaffolding board 700, so as to facilitate the installation of the ladder cage 300, the truss 500 and the scaffolding board 700 in place.

[0041] It can be understood that the hook of the lifting trolley 800 can be connected to four ladder cages 300 at the same time. The lifting trolley 800 lifts the four ladder cages 300, and the lifting trolley 800 can keep the positions of the four ladder cages 300 unchanged. Then the lifting trolley 800 carries the four ladder cages 300 and the operating platform to different sections on the beam body 200, so as to facilitate construction at different construction points of the beam body 200.

[0042] The manufacturing method of the bridge reconstruction work platform is simple. The guide beam 100, ladder cage 300, truss 500, scaffolding board 700, first lifting mechanism 400 and second lifting mechanism 600 and other components used are all common components with low cost. Compared with the cost of renting a bridge aerial work vehicle, the overall cost is lower.

[0043] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
