Description

Technical Field

[0001] The utility model relates to a steel structure sliding device.

Background Art

[0002] At present, long-span steel structures are widely used in construction projects. During the construction of steel structures, the existing technology generally installs them by means of aerial hoisting. However, for long-span and heavy steel structures in the relatively middle position of a building, due to limited construction site space during installation, it is impossible to use a crane or the crane cannot meet the hoisting requirements. Therefore, a steel structure sliding device needs to be used to install the long-span steel structure.

[0003] The prior art Chinese patent with the application number 202121489787.4 discloses a steel structure sliding device, which includes: a concrete structure frame with a working area inside; sliding rails arranged in the working area for carrying the steel structure; a vertical driving component arranged below the sliding rails for driving the sliding rails to lift and making their height higher and lower than the height of the concrete structure frame; and a horizontal driving component arranged at one end of the concrete structure frame for driving the steel structure to move along the sliding rails. However, this prior art needs to install a large number of side baffles beside the sliding track as supports for the hydraulic pusher to apply force. But in actual use, it is usually necessary to customize specific tracks, weld side baffles on the tracks, or install side baffles on the installed foundation, which increases the workload and thus affects the construction period process.

The pushing structure and the installation frame are both slidably arranged on the sliding track, and both ends of the hydraulic pusher are rotatably connected to the pushing structure and the installation frame respectively;

[0007] The installation frame is a U-shaped structure with an opening downward. Limiting parts that are inwardly retracted are arranged on both sides of the bottom of the installation frame for clamping the installation frame on the sliding track. The hydraulic cylinder is fixedly arranged through the installation frame, and the telescopic rod at the lower end of the hydraulic cylinder is connected to the pressing block, and the lower surface of the pressing block is in contact with the top of the sliding track;

[0008] A connecting plate is provided at the rear end of the mounting frame, the lower pressure rod is slidably inserted on the connecting plate, the tension spring is sleeved on the upper end of the lower pressure rod, and the two ends of the tension spring are respectively connected to the top of the lower pressure rod and the upper surface of the connecting plate; the roller is provided at the bottom of the lower pressure rod, the roller is rollingly connected to the upper surface of the sliding track, and the roller is connected to the angle sensor;

[0009] The angle sensor is electrically connected to a wireless communication module, and the wireless communication module, the hydraulic cylinder and the hydraulic jack are electrically connected to a control system.

[0010] Furthermore, the sliding track is an I-shaped track.

[0011] The advantages of the utility model are:

[0012] The utility model can realize the continuous pushing of the steel structure through the cooperation of the hydraulic pusher, the installation frame, the hydraulic device and other structures, thereby solving the problem that the prior art needs to modify the sliding track or add the corresponding side baffles, which requires the sliding track to be customized or the side baffles to be processed, which increases the cost or cycle.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Please refer to Figures 1 to 4 As shown, a steel structure sliding device of the present utility model includes a sliding track 1, a pushing structure 2, a hydraulic pusher 3, a mounting frame 4, a hydraulic cylinder 5, a pressing block 6, a downward pressing rod 7, a tension spring 8, a roller 9, an angle sensor 10, a wireless communication module 11, and a control system 12. The pushing structure 2 and the mounting frame 4 are both slidably arranged on the sliding track 1, and both ends of the hydraulic pusher 3 are rotatably connected to the pushing structure 2 and the mounting frame 4 respectively;

[0021] The mounting frame 4 is a U-shaped structure with an opening downward. Limiting parts 13 that are inwardly retracted are arranged on both sides of the bottom of the mounting frame 4 for clamping the mounting frame 4 on the sliding track 1; the hydraulic cylinder 5 is fixedly penetrated through the mounting frame 4, and a telescopic rod 14 at the lower end of the hydraulic cylinder 5 is connected to the pressing block 6, and the lower surface of the pressing block 6 is in contact with the top of the sliding track 1;

[0022] A connecting plate 15 is arranged at the rear end of the mounting frame 4. The downward pressing rod 7 is slidably inserted into the connecting plate 15. The tension spring 8 is sleeved on the upper end of the downward pressing rod 7, and both ends of the tension spring 8 are respectively connected to the top of the downward pressing rod 7 and the upper surface of the connecting plate 15; a roller 9 is arranged at the bottom of the downward pressing rod 7, and the roller 9 is in rolling connection with the upper surface of the sliding track 1, and the roller 9 is connected to the angle sensor 10;

[0023] The angle sensor 10 is electrically connected to the wireless communication module 11 , and the wireless communication module 11 , the hydraulic cylinder 5 , and the hydraulic jack 3 are electrically connected to a control system 12 .

[0024] In a specific implementation, a preferred embodiment is: the sliding track 1 is an I-shaped track.

[0025] In another embodiment of the present invention, the working process is as follows:

[0026] Multiple sliding devices are arranged in parallel, and the steel structure is placed on the sliding track 1 at the front end of the pushing structure 2; when pushing is required, the control system 12 controls the multiple sliding devices to act simultaneously: the telescopic rod 14 of the hydraulic cylinder 5 extends to drive the extrusion block 6 to squeeze the sliding track 1, so that the installation frame 4 is lifted up in the opposite direction, and the inward limit portion 13 at the bottom of the installation frame 4 is hooked on the sliding track 1 for fixing, and then the installation frame 4 is locked and fixed; then the hydraulic pusher 3 is extended to drive the pushing structure to slide forward along the sliding track 1, thereby driving the steel structure at the front end of the pushing structure 2 to move a corresponding distance;

[0027] When the hydraulic jack 3 stops extending, the telescopic rod 14 of the hydraulic cylinder 5 retracts, driving the installation frame 4 to move downward, and the lower limit part 13 moves downward to be movably connected with the sliding track 1; at this time, the installation frame 4 drives the connecting plate 15 to move downward, and the connecting plate 15 drives the pressing rod 7 to be pressed downward through the tension spring 8, so that the roller 9 and the upper surface of the sliding track 1 are in contact to achieve rolling connection; then the hydraulic jack 3 is retracted, driving the installation frame 4 at the rear end to move forward, and then the movement distance of the installation frame 4 is collected by the angle sensor 10 that cooperates with the rotation of the roller 9. The displacement information collected by the angle sensor 10 is uploaded to the control system 12 through the wireless communication module 11 to determine whether the movement displacement of each sliding device is consistent and how many cycles have been pushed. When the movement displacement of a certain sliding device is inconsistent, it can be adjusted by controlling the extension length of the corresponding hydraulic jack 3.

[0028] Repeat the above process to achieve the pushing work.

[0029] The utility model can realize the continuous pushing of the steel structure through the cooperation of the hydraulic pusher, the installation frame, the hydraulic device and other structures, thereby solving the problem that the prior art needs to modify the sliding track or add the corresponding side baffles, which requires the sliding track to be customized or the side baffles to be processed, which increases the cost or cycle. The utility model has a reasonable structure and a high degree of automation, which can greatly improve the work efficiency.
