Description

Technical Field

[0001] The utility model belongs to the field of mobile pavement, and in particular relates to a mobile pavement for a gantry crane crossing a road section used at a construction site. Background Art

[0002] In order to save space, two gantry cranes are required for one combined yard track line, and a cement road is arranged longitudinally in the center of the yard to realize unloading and loading. For the gantry crane crossing section, in order to prevent the cables from being crushed when the truck passes by, it is necessary to arrange cable troughs in the crossing section to protect the cables.

[0003] Due to the different models of gantry cranes, the distance between the center of the track and the center line of the cable drum varies to a certain extent. It is necessary to arrange two cable troughs within a distance of 800mm and the road surface should be strong and durable to ensure that trucks are not affected when passing through. There are two problems in the cement crossing section where the track sinks and the gantry crane cable is pressed:

[0004] (1) In order to prevent the cables from being crushed, the existing technology places the cables in channel steels and lays concrete on the edges of the channel steels. However, long-term rolling will crush the concrete on the edges of the channel steels. Without the protection of concrete, the channel steels will affect the normal traffic on the road section.

[0005] (2) When a gantry crane passes through a road section, the track may sink due to the rolling of heavy trucks passing by, and the sunken road surface needs to be repaired. However, in the existing technology, the road surface is cast as a whole, which is not convenient for repairing the sunken track. Summary of the invention

[0006] In view of the above technical problems, the present invention provides a mobile pavement for gantry crane-crossed road sections used in construction sites; the mobile pavement is provided with a reinforcement groove, and concrete is poured in the reinforcement groove, so that the concrete and steel structure are integrated to be more solid and reliable.

[0007] The utility model is realized by the following technical solutions:

[0008] A gantry crane-crossing section movable pavement applied to a construction site, comprising: a bottom steel plate, a first side steel plate, a second side steel plate, a first partition, a second partition and a third partition;

[0009] The bottom steel plate is in a rectangular shape, and the first side steel plate and the second side steel plate are respectively arranged on two opposite sides of the bottom steel plate; the first partition plate, the second partition plate and the third partition plate are arranged parallel to each other and are arranged in sequence between the first side steel plate and the second side steel plate;

[0010] Several groups of reinforcing steel bars are arranged between the first side steel plate and the first partition plate to form a first reinforcement groove; several groups of reinforcing steel bars are arranged between the second partition plate and the third partition plate to form a second reinforcement groove;

[0011] pouring concrete in the first reinforcement groove and the second reinforcement groove;

[0012] The bottom steel plate, the first partition plate and the second partition plate define a first cable trough; the bottom steel plate, the third partition plate and the second side steel plate define a second cable trough.

[0013] Furthermore, two lifting ear openings are provided on the first partition plate, and two lifting ear openings are provided on the third partition plate; the diameter of each lifting ear is in the range of 30-40 mm.

[0014] Furthermore, the bottom steel plate, the first side steel plate, the second side steel plate, the first partition plate, the second partition plate and the third partition plate are all made of Q235 steel with a thickness of 8-16 mm;

[0015] Further, each group of reinforcing steel bars includes two reinforcing steel bars crossing each other;

[0016] Furthermore, the reinforcing steel bars are made of φ14-18 mm steel bars.

[0017] Furthermore, the first side steel plate, the second side steel plate, the first partition plate, the second partition plate, and the third partition plate are all connected to the bottom steel plate by welding.

[0018] Furthermore, the first side steel plate, the second side steel plate, the first partition plate, the second partition plate and the third partition plate have the same height, and the height range is 100-200 mm.

[0019] Furthermore, the width of the first cable trough and the second cable trough is 150-200 mm.

[0020] Furthermore, the distance between the first side steel plate and the first partition is 150-200 mm; the distance between the second partition and the third partition is 200-300 mm.

[0021] Furthermore, C30 concrete is poured in the first reinforcement groove and the second reinforcement groove.

[0022] Beneficial technical effects of the utility model:

[0023] In order to facilitate the maintenance of the sunken road surface, the utility model adopts a mobile road surface, which is used as the road surface of the passing section around the track; when the track sinks and needs to be repaired, the road surface of the passing section is lifted open through the pre-reserved lifting lugs, and the road surface of the passing section is lifted back to its original position after the maintenance is completed, which solves the maintenance problem after the track sinks;

[0024] In order to solve the problem that the edge concrete of the cable trough is easily crushed and damaged when it is close to the edge of the track, the utility model adopts a first reinforcement groove and a second reinforcement groove in the mobile pavement. The reinforcement groove contains reinforcing steel bars, and concrete is poured in the first reinforcement groove and the second reinforcement groove to integrate the concrete with the steel structure, thereby protecting the edge of the mobile pavement from damage, making it stronger and more reliable, and thus being able to better protect the cables in the cable trough.
