Technical Field

[0001] The utility model relates to the technical field of steel structure lifting and sliding, in particular to a steel structure lifting and sliding device. Background Art

[0002] Existing steel structures, such as trusses, are lifted to the installation site by a crane during installation. During installation, the trusses are easily shaken when suspended in the air, which is not conducive to installation.

[0003] Existing lifting and sliding devices, such as patent application number CN202211022334X, include a track, a trolley slidably mounted on the track, a push plate mechanism, and a lifting mechanism. During use, the lifting mechanism raises the steel structure to the designed height, and the push plate mechanism pushes the steel structure laterally onto the trolley. The trolley then carries the steel structure and slides along the track to the installation location for installation. Existing lifting and sliding devices require the push plate mechanism to push the steel structure laterally onto the trolley. This process can easily cause the steel structure to topple over, potentially leading to safety accidents. Utility Model Content

[0024] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a steel structure lifting and sliding device includes a supporting structure 3, a track assembly 4, a lifting vehicle 5 and a lifting mechanism 6. The supporting structure 3 is used to lock one end of the track assembly 4 on the building body 7, and the other end of the track assembly 4 is horizontally suspended. The front side of the suspended end of the track assembly 4 is provided with an avoidance space for the steel structure to pass through. The lifting mechanism 6 is provided above the avoidance space and is used to lift the steel structure. The lifting vehicle 5 is slidably connected to the upper side of the track assembly 4. The track assembly 4 can be axially extended and retracted so that the lifting vehicle 5 can reach directly below the lifting mechanism 6. The upper side of the lifting vehicle 5 is provided with a liftable support surface for supporting the steel structure.

[0026] Through the above arrangement, first, the track assembly 4 can be retracted to facilitate avoiding the steel structure; second, after the steel structure moves to the top of the track assembly 4, the lifting vehicle 5 can move to the bottom of the steel structure, and the lifting mechanism 6 can place the steel structure vertically on the lifting vehicle 5, so that the steel structure is not easy to tip over; third, the lifting vehicle 5 can move the steel structure horizontally and adjust the height of the steel structure, so that the steel structure can be conveniently transported to the installation site for installation.

[0027] The support structure 3 of the present application can refer to a tire frame, the lifting vehicle 5 can refer to a scissor-type work vehicle and other devices, and the lifting mechanism 6 can refer to an electric or manual hoist and the like; when in use, the support structure 3 is first installed on one side of the building body 7, and the track assembly 4 is horizontally installed on the support structure 3. The support structure 3 ensures that the track assembly 4 has good strength and stability. Initially, as shown in FIG. Figure 1As shown, the track assembly 4 is in a retracted state, and there is an avoidance space adapted to the size of the steel structure between the suspended end of the track assembly 4 and the other side of the building body 7. The lifting mechanism 6 is installed on the building body 7 and is located above the avoidance space; the lifting vehicle 5 is close to the upper side of the suspended end of the track assembly 4; after the lifting mechanism 6 is connected to the steel structure on the ground, it lifts the steel structure upward, and the steel structure moves to the top of the avoidance space after passing the suspended end of the track assembly 4. The track assembly 4 is extended, and the suspended end of the track assembly 4 drives the lifting vehicle 5 to move to the bottom of the steel structure, as shown in FIG. Figure 5 As shown, the lifting mechanism 6 lowers the steel structure 200 and places the steel structure vertically on the supporting surface of the lifting vehicle 5. The lifting vehicle 5 moves along the track assembly 4, and the steel structure moves with the lifting vehicle 5 close to the installation position where the steel structure needs to be installed. When there is an error between the steel structure and the installation position, the lifting vehicle 5 adjusts the height of the steel structure up and down so that the steel structure can be aligned with the installation position. After the steel structure is installed at the installation position, the supporting surface of the lifting vehicle 5 descends and separates from the steel structure, and then the lifting vehicle 5 returns to the suspended end of the track assembly 4 to prepare for the next round of installation.

[0028] As an implementation method, the track assembly 4 includes two telescopic rails 41 parallel to each other, the telescopic rail 41 includes a fixed rail portion 411 and a sliding rail portion 412, one end of the fixed rail portion 411 is locked on the support structure 3, and one end of the sliding rail portion 412 is coaxially slidably connected to the other end of the fixed rail portion 411, and the sliding rail portions 412 of the two telescopic rails 41 are fixedly connected by a connecting rod 42. The track assembly 4 also includes a first linear drive 43 parallel to the telescopic direction of the telescopic rail 41, one end of the first linear drive 43 is locked on the support structure 3, and the other end of the first linear drive 43 is connected to the connecting rod 42.

[0029] Through the above arrangement, the first linear driver 43 drives the sliding rail portion 412 to move via the connecting rod 42 to adjust the length of the telescopic rail 41 .

[0030] The first linear drive 43 of the present application can adopt a hydraulic cylinder or a pneumatic cylinder. The length of the telescopic rail 41 is adjusted by the extension and contraction of the first linear drive 43. In this embodiment, when the first linear drive 43 is extended, the first linear drive 43 synchronously drives the sliding rail parts 412 of the two telescopic rails 41 to move forward synchronously through the connecting rod 42, and the telescopic rail 41 is extended; when the first linear drive 43 is shortened, the first linear drive 43 synchronously drives the sliding rail parts 412 of the two telescopic rails 41 to move backward synchronously through the connecting rod 42, and the telescopic rail 41 is shortened.

[0031] As an implementation method, the fixed track portion 411 is set as the first I-beam, the web of the first I-beam is set vertically, and a slide groove is formed on the left and right sides of the first I-beam. The sliding track portion 412 includes a second I-beam 4121 and two sliding plates 4122. The second I-beam 4121 has the same cross-section as the first I-beam and is coaxially arranged at the suspended end of the first I-beam. The sliding plates 4122 are adapted to the slide groove. One end of the two sliding plates 4122 is attached to the left and right sides of the web of the first I-beam and can slide along the slide groove. The other end of the two sliding plates 4122 is fixedly connected to the second I-beam 4121.

[0032] Through the above arrangement, the fixed rail portion 411 and the sliding rail portion 412 have good strength, and the sliding rail portion 412 can stably slide along the axial direction of the fixed rail portion 411 .

[0033] The first I-beam and the second I-beam 4121 of the present application can be purchased from the market. A sliding groove is formed between the web and the wing plate of the first I-beam on the left and right sides of the first I-beam. The extension direction of the sliding plate 4122 is parallel to or coincides with the extension direction of the sliding groove. When the end of the sliding plate 4122 is slidably connected in the sliding groove, the second I-beam 4121 can always be coaxial with the first I-beam during movement. In the present application, the left and right sides of the web of each first I-beam are fitted with a limiting plate, that is, the limiting plate clamps the web of the first I-beam, so that the second I-beam 4121 is more stable during movement. The sliding plate 4122 is welded to the second I-beam. On the side of the web of 4121, the upper surface of the second I-beam 4121 is flush with the upper surface of the first I-beam; after the lifting mechanism 6 of the present application lifts the steel structure, the telescopic rail 41 extends, the second I-beam 4121 moves forward, the second I-beam 4121 is separated from the first I-beam, and the telescopic rail 41 extends. At this time, the lifting vehicle 5 is located on the upper side of the second I-beam 4121. After the steel structure is lowered onto the lifting vehicle 5, the second I-beam 4121 moves backward, the telescopic rail 41 shortens, and the end of the second I-beam 4121 is against the end of the first I-beam, so that the lifting vehicle 5 can move smoothly backward to the upper side of the first I-beam.

[0034] As an implementation method, the sliding plate 4122 on the inner side of the telescopic rail 41 is fixedly connected to the sliding plate 4122 on the inner side of another telescopic rail 41 through the connecting rod 42 .

[0035] As an implementation method, the rail assembly 4 also includes a mounting seat 44, which is vertically mounted on the support structure 3, and the end of the fixed rail portion 411 away from the sliding rail portion 412 is vertically fixedly connected to the mounting seat 44, and the end of the first linear drive 43 away from the connecting rod 42 is mounted on the mounting seat 44.

[0036] Through the above arrangement, the two telescopic rails 41 and the first linear drive 43 are connected together via the mounting seat 44 , thereby increasing the structural compactness of the rail assembly 4 .

[0037] The mounting seat 44 of the present application can be mounted on the supporting structure 3 by welding or fasteners.

[0038] As an implementation method, the lifting vehicle 5 includes a chassis 51, wheels 52, a lifting platform 53 and a second linear drive 54. The wheels 52 are rotatably connected to the left and right sides of the chassis 51 and are arranged on the upper side of the two telescopic rails 41. The lifting platform 53 is horizontally installed above the chassis 51 through the second linear drive 54. The second linear drive 54 can drive the lifting platform 53 to move up and down.

[0039] The chassis 51 of the present application is provided with two wheels 52 on the left and right sides respectively. The two wheels 52 on the left roll on one of the telescopic rails 41, and the two wheels 52 on the right roll on the other telescopic rail 41, so that the lifting vehicle 5 has better stability; the second linear drive 54 can adopt a hydraulic cylinder or an air cylinder and other devices, and the second linear drive 54 is vertically installed between the chassis 51 and the lifting platform 53; the support surface is set on the upper side of the lifting platform 53 to support the steel structure.

[0040] As an implementation method, the support structure 3 includes a grid frame structure 31 that can be vertically installed on the building body 7 by fasteners.

[0041] As an implementation manner, the support structure 3 further includes a support plate 32 that can be horizontally mounted on the building body 7 , and the support plate 32 supports the lower side of the telescopic rail 41 .

[0042] Through the above arrangement, the stability of the telescopic track 41 is increased, and the telescopic track 41 is prevented from deforming downward.
