[0002] Steel components refer to steel structure composite components that can bear and transfer loads and are made of steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-shaped steels that are cold-bent or welded and connected through connectors.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] See also Figure 1-Figure 9 In the embodiment of the present invention, the large-span steel member hoisting equipment based on multi-point suspension anti-sway includes a truss 1, which is connected to a hook on an electric hoist through a rope; the large-span steel member hoisting equipment based on multi-point suspension anti-sway also includes: a connecting plate 2, two of which are symmetrically and movably provided on the truss 1, and the two connecting plates 2 are connected to a spacing adjustment mechanism installed on the truss 1, and the spacing adjustment mechanism can drive the two connecting plates 2 to move toward each other; a loading mechanism, which is arranged below the connecting plate 2 and is used to support the end of the steel member, and the loading mechanism is connected with a cross Column 15, the transverse column 15 cooperates with the traction belt 8 arranged under the connecting plate 2, the traction belt 8 is used to lift the loading mechanism through the transverse column 15, so that the loading mechanism drives the steel structure to rise, and the traction belt 8 is connected with the tightening and stabilizing mechanism installed on the connecting plate 2; a side limiting mechanism, a group of which is provided on each side of the loading mechanism, the side limiting mechanism and the tightening and stabilizing mechanism are triggered when the steel structure is lifted, the side limiting mechanism can move along the length direction of the truss 1, and the tightening and stabilizing mechanism can perform a tightening action on the transverse column 15.

[0032] Specifically, two assembly plates 27 are provided on the truss 1, and each end of the assembly plate 27 is provided with a hook for connecting with an electric hoist. Furthermore, the assembly plate 27 can be connected to the electric hoist through multiple ropes, which is convenient for multi-point suspension of multiple steel components, thereby ensuring the stability of the steel components during the lifting process and avoiding the deviation of the steel components.

[0033] When in use, the steel member is located between the two groups of the loading mechanisms, and the spacing adjustment mechanism works to drive the two connecting plates 2 to drive the two groups of the loading mechanisms to approach each other until the two groups of the loading mechanisms can support the two ends of the steel member; after the steel member is lifted, under the action of the gravity of the steel member, the side limiting mechanism and the tightening and stabilizing mechanism will be triggered, so that the side limiting mechanism will move along the length direction of the truss 1 to play a role of enclosure on both sides of the steel member, so as to avoid the displacement of the steel member in its own width direction during the lifting process, which may cause the steel member to accidentally fall and cause dangerous accidents, and the tightening and stabilizing mechanism will tighten the cross column 15, so that the connection between the traction belt 8 and the cross column 15 is more stable, which can prevent the steel member from shaking due to the gap between the traction belt 8 and the cross column 15 during the lifting process; therefore, the lifting equipment can effectively improve the safety of lifting work, provide effective protection for safe production, and is suitable for popularization and use.

[0034] Please refer again Figure 6 and Figure 7 The loading mechanism includes a guide plate 16 fixedly connected to the horizontal column 15 and a receiving seat 17 slidably fitted with the guide plate 16. The receiving seat 17 is arranged in an "L" shape, and two sets of elastic connectors are arranged between the receiving seat 17 and the guide plate 16. The two sets of side limit mechanisms are respectively located on both sides of the receiving seat 17. The elastic connector includes a guide cylinder 19 fixedly mounted on the receiving seat 17, a telescopic rod 20 fixedly connected to the guide plate 16 and slidably fitted with the guide cylinder 19, and a second cylindrical spring 22 arranged inside the guide cylinder 19. The telescopic rod 20 is also fixed to a round table 18 slidably arranged inside the guide cylinder 19. The two ends of the second cylindrical spring 22 are respectively connected to the inner wall of the guide cylinder 19 and the round table 18.

[0035] After the two ends of the steel component are respectively located on the two receiving seats 17, the lifting begins. Under the action of the gravity of the steel component, the receiving seat 17 and the steel component move downward relative to the guide plate 16. Accordingly, the telescopic rod 20 slides toward the outside of the guide cylinder 19, causing the second cylindrical spring 22 to be compressed. During this process, the side limiting mechanism will be triggered to enclose the side of the steel component to prevent the steel component from accidentally falling during the lifting process and causing a dangerous accident.

[0036] The side limiting mechanism includes a guide member 21 fixedly installed on the side of the receiving seat 17 and a cross arm 24 slidably connected to the guide member 21, and a second column 26 is fixedly provided on the cross arm 24 through a vertical arm 25, and the second column 26 cooperates with a second limiting plate 23 fixedly installed on the guide plate 16; wherein, the second limiting plate 23 is provided with a second through groove 2301 adapted to the second column 26, the second through groove 2301 is inclined, and the second column 26 passes through the second through groove 2301 and is slidably connected to the second limiting plate 23.

[0037] During the sliding process between the guide plate 16 and the receiving seat 17, the second column 26 will slide and cooperate with the second limiting plate 23 through the second through groove 2301, so that the second column 26 drives the cross arm 24 to make way through the vertical arm 25, so that the cross arm 24 slides toward the center direction of the steel component, so that the cross arm 24 can enclose the two sides of the receiving seat 17 to prevent the steel component from shifting along its own width direction during lifting.

[0038] Furthermore, if the cross arm 24 is directly fixed on the receiving seat 17, the corresponding enclosure effect can also be achieved. However, in this case, the receiving seat 17 has a certain depth. During actual construction, on the one hand, it is more difficult to place the steel member on the receiving seat 17. On the other hand, after the steel member is hoisted to the target position, the difficulty of transferring the steel member from the receiving seat 17 is also increased. In this application, the cross arm 24 is movably arranged. Initially, the two sides of the receiving seat 17 are not enclosed. In order to facilitate material discharge from the side of the receiving seat 17, after the steel component is lifted, under the action of the gravity of the steel component, relative sliding occurs between the guide plate 16 and the receiving seat 17, prompting the cross arm 24 to move, and the two sides of the receiving seat 17 are enclosed. After the steel component is lifted to the target position and the effect of the gravity of the steel component on the receiving seat 17 is released (that is, the receiving seat 17 lands), the guide plate 16 and the receiving seat 17 return to their initial state, and the cross arm 24 retracts, so as to facilitate the transfer of the steel component from the receiving seat 17.

[0039] It should be added that, during actual construction, the loading mechanism can be directly used as a base for placing steel components in the workshop. When the steel components need to be lifted, the traction belt 8 is connected to the cross column 15, and then the lifting can be started, thereby facilitating production work.

[0040] Please refer again Figure 5 , Figure 8 as well as Fig. 9The tightening and stabilizing mechanism includes two horizontal plates 6 connected to the connecting plate 2 through multiple groups of elastic support members, two vertical plates 7 are fixedly provided at the bottom of the horizontal plate 6, the traction belt 8 is provided at one end of the vertical plate 7 away from the horizontal plate 6, and a group of restraint components are provided on both sides of the horizontal plate 6. The elastic support member includes a column 3 fixed on the horizontal plate 6 and slidably connected to the connecting plate 2, a first cylindrical spring 5 sleeved on the outer periphery of the column 3, and a circular boss 4 fixedly provided at one end of the column 3 away from the horizontal plate 6, and the two ends of the first cylindrical spring 5 are respectively connected to the circular boss 4 and the connecting plate 2.

[0041] A gap is reserved between the two horizontal plates 6, and the constraint assembly includes a slider 12 slidably arranged in the gap and a sleeve plate 9 slidably mounted on the vertical plate 7. The two sleeve plates 9 on the same side are fixedly connected by a connecting rod 10, and a push plate 11 is provided between the connecting rod 10 and the slider 12, one end of the push plate 11 is hinged to the connecting rod 10, and the other end is hinged to the slider 12; wherein, a first column 13 is also fixedly provided on the slider 12, and a first limiting plate 14 cooperating with the first column 13 is fixedly connected to the connecting plate 2, and a first through groove 1401 adapted to the first column 13 is provided on the first limiting plate 14, and the first through groove 1401 is inclined, and the first column 13 passes through the first through groove 1401 and is slidably connected to the first limiting plate 14.

[0042] When the steel structure is lifted, the gravity of the steel structure will cause the cross plate 6 to move away from the connecting plate 2. Accordingly, the first column spring 5 is compressed, and the first column 13 slides with the first limiting plate 14 through the first through groove 1401, thereby causing the first column 13 to drive the slider 12 to give way. Specifically, the slider 12 slides toward the center in the gap between the two cross plates 6, and pushes the sleeve plate 9 to slide on the vertical plate 7 away from the cross plate 6 through the push plate 11. Therefore, the sleeve plate 9 can restrain the traction belt 8 and tighten the cross column 15, thereby enhancing the stability of the connection between the traction belt 8 and the cross column 15 and preventing the steel structure from shaking during lifting.

[0043] After the steel structure is hoisted to the target position, the truss 1 moves downward. At this time, the first column spring 5 and the second column spring 22 will rebound to reset each component, that is, the sleeve plate 9 releases the tightening state of the cross column 15, and the cross arm 24 retracts to facilitate the separation of the steel structure from the receiving seat 17.

[0044] In detail, the inner sides of the two transverse plates 6 are provided with guide grooves 601 adapted to the slider 12, and the slider 12 is slidably engaged in the gap between the two transverse plates 6 through the guide grooves 601, so that the slider 12 can slide along the length direction of the transverse plate 6.

[0045] Please refer again Figure 1 , Figure 3 as well as Fig. 9 The spacing adjustment mechanism includes a bidirectional screw rod 29 rotatably mounted on the truss 1, two threaded sleeves 30 symmetrically sleeved on the bidirectional screw rod 29 and threadedly connected to the bidirectional screw rod 29, and a driving motor 28 mounted on the side of the truss 1, the output end of the driving motor 28 is connected to the bidirectional screw rod 29, the two threaded sleeves 30 are respectively fixed to the two connecting plates 2, and a guide sleeve 32 is also fixed on the two connecting plates 2, and the two guide sleeves 32 are slidably fitted with a guide rod 31 fixedly mounted on the truss 1.

[0046] During operation, the driving motor 28 drives the bidirectional screw 29 to rotate. Under the guiding action of the guide sleeve 32 and the guide rod 31, the two threaded sleeves 30 can be threadedly matched with the bidirectional screw 29 to move closer to or away from each other, so that the staff can adaptively adjust the distance between the two receiving seats 17 according to the length of the dry component, thereby improving the practicality of the equipment.

[0047] As another embodiment of the present invention, a method for hoisting a steel member is also proposed, using the hoisting equipment, comprising the following steps:

[0048] Step 1: The electric hoist controls the movement of the truss 1 so that the two sets of loading mechanisms are located at the two ends of the steel member respectively;

[0049] Step 2: The spacing adjustment mechanism works to drive the two sets of loading mechanisms to move closer to each other until the two sets of loading mechanisms can support the ends of the steel members after lifting up;

[0050] Step 3: The two groups of loading mechanisms lift the steel member, the tightening and stabilizing mechanism and the side limiting mechanism are triggered, the tightening and stabilizing mechanism tightens the cross column 15, and the side limiting mechanism blocks both sides of the steel member;

[0051] Step 4: The steel structure is hoisted to the target position, the tightening and stabilizing mechanism and the side limiting mechanism are reset, and the steel structure is separated from the loading mechanism.

[0052] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0053] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

A method for hoisting a steel member, using the large-span steel member hoisting equipment based on multi-point suspension and anti-swaying as claimed in claim 1, characterized in that: The following steps are involved: Step 1: The electric hoist controls the truss (1) to move so that the two sets of loading mechanisms are located at the two ends of the steel member respectively; Step 2: The spacing adjustment mechanism works to drive the two sets of loading mechanisms to move closer to each other until the two sets of loading mechanisms can support the ends of the steel members after lifting up; Step 3: The two groups of loading mechanisms lift the steel member, the tightening and stabilizing mechanism and the side limiting mechanism are triggered, the tightening and stabilizing mechanism tightens the crossbar (15), and the side limiting mechanism blocks both sides of the steel member; Step 4: The steel structure is hoisted to the target position, the tightening and stabilizing mechanism and the side limiting mechanism are reset, and the steel structure is separated from the loading mechanism.
