Description

Technical Field

[0001] The invention belongs to the technical field of component turnover, and in particular relates to a turning device for a steel structure. Background Art

[0002] At present, the steel structure module (or steel structure member, steel frame) is welded by steel sections. After the steel structure module is formed, the height direction is placed horizontally on the ground. Later, it needs to be erected (that is, the steel structure module needs to be turned over 90 degrees) for vertical installation or installation of other accessories. At present, the turning method of the steel structure module from horizontal to vertical is: the top of the steel structure module is hoisted by a hoisting device such as a crane, and then the crane gradually lifts the top of the steel structure module. During the lifting process, the crane needs to move synchronously with the change of the position of the top of the steel structure module until the steel structure module is completely erected (the position after erection is the position of the non-hoisting end of the steel structure module). The above method has the following defects:

[0003] 1. During the lifting process, the synchronous movement of the trolley will cause the steel structure module to shake (the trolley and the steel structure module are flexibly connected), making the turning work difficult and seriously affecting the work efficiency;

[0004] 2. There are potential safety hazards. Summary of the invention

[0005] The present invention provides a turning device for a steel structure, so as to solve the problem that the lifting equipment shakes when it moves synchronously, making the turning work difficult and affecting the work efficiency.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a turning device for a steel structure, including a lifting device and a steel structure, a track is provided under the lifting device, a sliding seat is movably installed on the track, a hinged seat is hinged on the sliding seat, a connecting mechanism is provided on the hinged seat, one end of the steel structure is connected to the lifting device, and the other end of the steel structure is fixedly installed on the connecting mechanism.

[0007] As an improvement, the connection mechanism includes a positioning plate fixedly mounted on the hinge seat, the positioning plate is provided with a positioning hole matched with the shape of the steel structure; a plurality of locking members are provided between the positioning plate and the steel structure.

[0008] As a further improvement, a plurality of fixing blocks are provided on both sides of the positioning plate, and the locking member is threadedly mounted on each of the fixing blocks, and the end of the locking member abuts against the steel structure member.

[0009] As a further improvement, at least two positioning plates are provided on the hinge seat, and each positioning plate is fixedly mounted on the hinge seat via a plurality of L-shaped connecting plates.

[0010] As a further improvement, the articulated seat includes a plurality of articulated ear plates arranged on the sliding seat, each of the articulated ear plates is hinged with a wedge block, all the wedge blocks are provided with a mounting plate, and the positioning plate is fixedly mounted on the mounting plate.

[0011] As a further improvement, a cushion block is provided below the mounting plate at one end away from the hinged ear plate, and the cushion block is fixedly mounted on the slide seat.

[0012] As a further improvement, a mounting seat is provided at the end of the track away from the lifting end of the steel structure, and a traction device is provided on the mounting seat; a connecting ear plate is provided on the sliding seat, and the connecting ear plate is connected to the traction rope on the traction device.

[0013] As a further improvement, a support block is provided on the track at a position corresponding to the lifting end of the steel structure.

[0014] After adopting the above technical solution, the effects of the present invention are:

[0015] Since the turning over device includes a lifting device and a steel structure, a track is provided at the bottom of the lifting device, a slide is movably installed on the track, an articulated seat is hinged on the slide, a connecting mechanism is provided on the articulated seat, one end of the steel structure is connected to the lifting device, and the other end of the steel structure is fixedly installed on the connecting mechanism. Therefore, when the steel structure is turned over, the lifting device drives one end of the steel structure to be lifted, and since the other end of the steel structure is fixedly installed on the connecting mechanism, the lifting device does not need to be moved during the lifting process, and the other end of the steel structure will drive the slide to move along the track toward the lifting end. During the gradual movement and lifting, the articulated seat will rotate synchronously with the steel structure until the steel structure is completely erected (the position after erection is the position of the lifting end of the steel structure module), and then the steel structure is separated from the connecting mechanism, and the lifting device moves the erected steel structure again.

[0016] To sum up, by adopting the turning device, the turning work of the steel structure can be completed without moving the lifting equipment, and during the turning work, the connecting end of the steel structure and the connecting mechanism will move synchronously with the change of the lifting height through the sliding seat, thereby greatly reducing the shaking of the steel structure during the lifting process. At the same time, it effectively reduces the difficulty of turning the steel structure, greatly improves the work efficiency, and makes the work safe and reliable.

[0017] Since the connecting mechanism includes a positioning plate fixedly mounted on the hinge seat, the positioning plate is provided with a positioning hole that matches the shape of the steel structure; a plurality of locking members are provided between the positioning plate and the steel structure, so that when the steel structure is fixed, the steel structure is inserted into the positioning hole and fixed to the positioning plate through the locking members, the structure is simple, the fixing effect is good, and it will not interfere with the operation of the hinge seat.

[0018] Since multiple fixing blocks are provided on both sides of the positioning plate, each fixing block is threadedly installed with a locking piece, and the end of the locking piece is abutted against the steel structure, so that the steel structure is fixed to the positioning plate through the cooperation of the locking piece and the fixing block. The structure is simple and the operation process is convenient and fast.

[0019] Since at least two positioning plates are provided on the articulated seat, the reliability of positioning and fixing of the steel structure is improved; since each positioning plate is fixedly mounted on the articulated seat by multiple L-shaped connecting plates, the structure is simple, the connection with the articulated seat is convenient, and the fixing reliability of the positioning plate on the articulated seat is high.

[0020] Since the articulated seat includes multiple articulated ear plates arranged on the sliding seat, each articulated ear plate is hinged with a wedge block, all the wedge blocks are provided with mounting plates, and the positioning plate is fixedly installed on the mounting plate; a pad is provided under the mounting plate away from one end of the articulated ear plate, and the pad is fixedly installed on the sliding seat, so that through the cooperation of the wedge block and the pad, not only will the articulation work not be affected, but the mounting plate can also be in a horizontal state, thereby facilitating the positioning and cooperation of the steel structure and the positioning plate.

[0021] Since a mounting seat is provided at the end of the rail far away from the lifting end of the steel structure, a traction device is provided on the mounting seat; a connecting ear plate is provided on the slide, and the connecting ear plate is connected to the traction rope on the traction device, so that the slide is pulled by the traction device to ensure the stability of the movement of the steel structure during the lifting work, which helps to avoid the problem of sliding during the lifting work and further improves the reliability of use and the safety of work.

[0022] Since a support block is provided on the track at a position corresponding to the lifting end of the steel structure, the lifting end of the steel structure is supported by the support block, which helps to make the two ends of the steel structure at the same height so that the steel structure and the connecting mechanism can be fixedly connected; at the same time, it can play a role in blocking and limiting the slide.
