[0003] The steel beams are heavy, and are usually fixed by sleeving flexible belts or steel wires on both ends of the steel beams, and then hoisted to the top of the steel roof truss by a hoisting device. However, since the steel beams are in linear contact with the flexible belts or steel wires, the risk of the steel beams slipping off the sleeving part of the steel wires is easy to occur, and the safety hazard is high.

[0034] Please refer to Figures 1-4The first aspect of the embodiments of the present application provides a hoisting device, which comprises a clamping mechanism 5 for placing a steel beam 2 and a hoisting mechanism 4 for driving the clamping mechanism 5. Through the cooperation of the clamping mechanism and the hoisting mechanism 4, the safety of hoisting the steel beam 2 to the steel roof truss 1 is improved.
[0035] The clamping mechanism 5 comprises a seat body 51, a first limiting piece 53 and a second limiting piece 54. The seat body 51 has a groove 52 for placing a columnar piece, and the opening of the groove 52 is arranged on the side wall of the seat body 51. The first limiting piece 53 is arranged on the seat body 51, and the first limiting piece 53 has a limiting plate 531 which can operatively shield at least part of the opening of the groove 52. The second limiting piece 54 is arranged on the first limiting piece 53, and the second limiting piece 54 can operatively extend into the groove 52 so that the spacing between the second limiting piece 54 and the groove bottom of the groove 52 is adjustable.
[0036] It can be understood that the opening of the groove 52 is arranged on the side wall of the seat body 51, so that the groove 52 has a groove wall which can be used to bear the steel beam 2. The contact area between the steel beam 2 and the groove wall is large, and the corresponding friction force is also large, so the steel beam 2 is not easy to slip off, and the safety is improved. The first limiting piece 53 can close the opening of the groove 52, that is, after the steel beam 2 is placed in the groove 52, the first limiting piece 53 can block the steel beam 2 in the groove 52, so that it cannot slide out from the opening of the groove 52. Further, by adjusting the length of the second limiting piece 54 extending into the groove 52, the second limiting piece 54 can abut the steel beam 2 against the groove bottom of the groove 52, thereby limiting the position of the steel beam 2. When the clamping mechanism 5 is lifted by the hoisting mechanism 4, the first limiting piece 53 and the second limiting piece 54 cooperate to enable the steel beam 2 to remain relatively stationary in the groove 52, greatly improving the safety of hoisting the steel beam 2.
[0037] In some embodiments, the first limiting piece 53 can be a door plate which is hinged to the side wall of the seat body 51 near the opening of the groove 52. By rotating the door plate, the opening of the groove 52 can be shielded. Of course, a fastening piece is also arranged on the seat body 51 to lock the door plate after the door plate shields the opening of the groove 52, so that the door plate can keep shielding the opening of the groove 52.
[0038] Please refer to Figure 2 In some embodiments, the top wall of the seat body 51 is provided with a first through hole which communicates with the groove 52, and the limiting plate 531 is arranged in the groove 52. The first limiting piece 53 further comprises a connecting piece 532 which is arranged through the first through hole, one end of the connecting piece 532 is connected to the limiting plate 531, and the other end of the connecting piece 532 is located outside the seat body 51. The limiting plate 531 is operatively located in the first through hole.
[0039] Specifically, by pulling the part of the connecting piece 532 outside the seat body 51, the limiting plate 531 can be moved in the vertical direction, and the opening of the groove 52 can be shielded. The first through hole is arranged on the top wall of the seat body 51, that is, the limiting plate 531 will automatically approach the side wall of the groove 52 under the action of gravity, thereby shielding the opening of the groove 52. At the same time, the mutual restriction of the connecting piece 532 and the first through hole can also make the limiting plate 531 keep shielding the opening of the groove 52, which is simple to operate and has high safety performance.
[0040] In some embodiments, the connecting piece 532 can be a columnar piece with straight edges, such as a triangular prism or a T-shaped column. The shape of the first through hole matches the shape of the connecting piece 532. The shape of the connecting piece 532 and the shape of the first through hole make the connecting piece 532 not easy to rotate, and the limiting plate 531 is not easy to rotate, which has a good limiting effect on the steel beam 2.
[0041] Of course, please refer to Figures 2-3 In some embodiments, the side wall of the groove 52 close to the bottom surface of the seat body 51 is provided with a limiting groove 521 capable of accommodating the bottom end of the limiting plate 531. That is, by setting the limiting groove 521 to limit the limiting plate 531, the limiting plate 531 is not easy to rotate.
[0042] In some embodiments, the top wall of the seat body 51 is provided with two first limiting pieces 53, and the connecting pieces 532 of the two first limiting pieces 53 are connected by a pull rod 533, and the pull rod 533 is located above the seat body 51.
[0043] The seat body 51 is provided with two first through holes to match the connecting pieces 532 of the two first limiting pieces 53, respectively. The two connecting pieces 532 are connected by the pull rod 533, so that the two connecting pieces 532 and the pull rod 533 form a connecting rod structure. At this time, the connecting piece 532 is limited by the other connecting piece 532 and cannot rotate compared with the first through hole, that is, the limiting plate 531 is not easy to rotate, which has a good limiting effect on the steel beam 2. The second limiting piece 54 can be arranged on the two first limiting pieces 53 to increase the ability of the clamping mechanism 5 to lock the steel beam 2 in the groove 52, and further improve the safety.
[0044] In some embodiments, the first limiting piece 53 further comprises a support frame 534, the support frame 534 is provided with a second through hole, and the connecting piece 532 is further arranged in the second through hole; the connecting piece 532 is sleeved with a compression spring 535, and the compression spring 535 is located between the support frame 534 and the limiting plate 531.
[0045] The first through hole and the second through hole cooperate, and the limiting capacity of the connecting piece 532 is good, so that the stability during pulling the connecting piece 532 can be improved. When the connecting piece 532 is lifted upward, the limiting plate 531 can be in contact with the compression spring 535 and make the compression spring 535 compressed. After the work personnel places the steel beam 2 in the groove 52 or takes out the steel beam 2 from the groove 52, it is not necessary for the work personnel to manually press the connecting piece 532 or the pull rod 533. After the compressed compression spring 535 is no longer stressed, the compression spring 535 will reset and push the limiting plate 531 to fall, so that the operation steps of the work personnel are reduced.
[0046] Of course, in order to reduce the overall weight of the hoisting device 3, the top wall of the seat body 51 can be relatively thin, and the first through hole is a strip-shaped hole, and the limiting plate 531 can be arranged in the first through hole. The shape of the second through hole matches the shape of the connecting piece 532, and the limiting plate 531 is limited by the support frame 534, so that the limiting plate 531 or the limiting plate 531 and the connecting piece 532 are prevented from completely separating from the first through hole. During use, the work personnel does not need to be careful to operate, and the work efficiency can be improved.
[0047] Please refer to Figures 2-4 In some embodiments, the limiting plate 531 is provided with a threaded hole, and the threaded hole is axially directed to the groove bottom of the groove 52; and the second limiting piece 54 includes a screw rod 541, and the screw rod 541 is threadedly connected with the threaded hole.
[0048] It can be understood that by rotating the second limiting piece 54, the length of the second limiting piece 54 in the groove 52 can be adjusted, so that the second limiting piece 54 can tightly abut the steel beam 2 in the groove 52.
[0049] In some embodiments, one end of the screw rod 541 directed to the groove 52 is provided with an abutting plate 542, and the other end of the screw rod 541 is provided with a handle 543.
[0050] The area of the abutting plate 542 is greater than the area of the end surface of the screw rod 541. By increasing the contact area between the second limiting piece 54 and the steel beam 2, the pressure is reduced, and the surface of the steel beam 2 is prevented from being damaged by the second limiting piece 54. Of course, a rubber pad can also be arranged on the side of the abutting plate 542 directed to the steel beam 2, so as to further reduce the possibility of damaging the steel beam 2, increase the friction between the abutting plate 542 and the steel beam 2 by using the characteristics of rubber, improve the stability of the steel beam 2 in the groove 52, and improve the safety.
[0051] In some embodiments, the side wall of the groove 52 close to the top surface of the seat body 51 is provided with an avoiding groove 511 capable of accommodating the second limiting piece 54, so as to avoid the second limiting piece 54 from colliding with the seat body 51 during movement of the limiting plate 531.
[0052] In some embodiments, the side wall of the limiting plate 531 facing away from the groove 52 is provided with an extension cylinder 544, the extension cylinder 544 is provided with an inner thread coaxial with the screw hole, and the screw rod 541 is threadedly connected with the extension cylinder 544.
[0053] In order to reduce the overall weight of the hoisting device 3, the thickness of the limiting plate 531 can be set to be relatively thin, and the normal use of the screw rod 541 can be ensured by arranging the extension cylinder 544, so that the screw rod 541 can be stably threadedly connected.
[0054] In some embodiments, the hoisting mechanism 4 includes two support seats 42 arranged opposite to each other along the length direction of the groove 52, and two hoisting ropes 41 detachably connected with the support seats 42, and the other ends of the two hoisting ropes 41 are used to connect a driving mechanism. At this time, the two hoisting ropes 41 and the seat body 51 form a stable triangular relationship, and the driving mechanism is not easy to shake the locking mechanism during the process of driving the hoisting rope 41 to pull the locking mechanism to move, and the stability and safety are high, and the driving mechanism can be any kind of hoisting device, such as a hoisting vehicle or a gantry crane.
