TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure construction, in particular to a hoisting device and a hoisting method. BACKGROUND

[0002] In large-span space structures such as terminals and stadiums, a pin shaft is usually used to connect the ears on the steel beams and the steel columns. The ears are usually welded on the ground and then hoisted together with the steel beams and the steel columns to the predetermined position. However, after the installation of the steel beams and the steel columns is completed, due to installation errors, the position of the ear mounting hole will be misaligned, resulting in the pin shaft being unable to be smoothly inserted into the mounting hole.

[0003] In order to avoid the above situation, in the prior art, only the ears of the steel beams are welded on the ground, while the ears of the steel columns are repositioned according to the actual installation position of the steel beams and the steel columns and welded in the air. Due to the large size and heavy weight of the ears, a tower crane is usually used to hoist the ears. However, due to the obstruction of the steel beams, the tower crane cannot directly hoist the ears above the steel columns. Therefore, during the actual hoisting, the tower crane is usually used to hoist the ears to the vicinity of the installation position, and then the operator manually moves the ears between the steel beams and the steel columns, and finally the ears are welded and fixed. Using the above method to install the ears, the installation is difficult due to the limited operating space of the high-altitude operation, the construction efficiency is low, and the safety risk of the operator is increased. SUMMARY

[0004] Therefore, the present application provides a hoisting device and a hoisting method to solve the problem that the ears are hoisted to the vicinity of the installation position by the tower crane, and then installed by the inverted chain cooperation method, which is difficult to install due to the limited operating space of the high-altitude operation, the construction efficiency is low, and the safety risk of the operator is increased.

[0046] According to the embodiments of the present application, in one aspect, a hoisting device is provided for hoisting a first fixing member 1 between a first to-be-mounted member 2 and a second to-be-mounted member 3, the first to-be-mounted member 2 and the second to-be-mounted member 3 are arranged at an angle to each other, the hoisting device comprises: a hoisting member; a support member 4, the first fixing member 1 is detachably connected to the support member 4, the first fixing member 1 is arranged close to an end of the support member 4, and the size of the support member 4 is greater than the size of the first fixing member 1 in a direction parallel to the extension length of the support member 4, and the size of the support member 4 is smaller than the size of the first fixing member 1 in a direction perpendicular to the extension length of the support member 4, and the hoisting part 41 is arranged on the support member 4; a connecting member 5, one end of which is connected to the hoisting part 41, and the other end of which is connected to the hoisting member, for keeping the center of gravity of the support member 4 balanced.

[0047] By arranging the first fixing member 1 close to the end of the support member 4, when hoisting, the hoisting member can hoist the support member 4 to hoist the first fixing member 1 between the first to-be-mounted member 2 and the second to-be-mounted member 3, and because the size of the support member 4 is greater than the size of the first fixing member 1 in a direction parallel to the extension length of the support member 4, when the hoisting member hoists the support member 4 to the vicinity of the mounting position, the first fixing member 1 can be between the first to-be-mounted member 2 and the second to-be-mounted member 3, and because the size of the support member 4 is smaller than the size of the first fixing member 1 in a direction perpendicular to the extension length of the support member 4, the support member 4 will not interfere with the installation of the first fixing member 1 between the first to-be-mounted member 2 and the second to-be-mounted member 3. The hoisting device in the embodiment can prevent the connecting member 5 from being blocked by the first to-be-mounted member 2 or the second to-be-mounted member 3, and can directly hoist the first fixing member 1 to the specified position without being limited by the operation space, thereby reducing the installation difficulty, improving the construction efficiency, reducing the safety risk of the operator, and reducing the safety protection investment cost.

[0048] ​In order to prevent the connecting piece 5 from being blocked by the first to-be-installed piece 2 and the second to-be-installed piece 3 during hoisting, the hoisting part 41 can be arranged away from the first fixing piece 1, as long as the center of gravity of the supporting piece 4 can be kept balanced during hoisting.

[0049] In one embodiment, the first fixing piece 1 is a first ear plate, the first to-be-installed piece 2 is a steel column, and the second to-be-installed piece 3 is a steel beam. As a transformable implementation, the first fixing piece 1 can also be a flat plate structure, which is welded and fixed with the first to-be-installed piece 2 and the second to-be-installed piece 3. The first fixing piece 1 can also be other connecting structures, as long as it can connect the end portions of the first to-be-installed piece 2 and the second to-be-installed piece 3. As a transformable implementation, the first to-be-installed piece 2 and the second to-be-installed piece 3 can also be other structures arranged at an angle to each other, which is not limited here.

[0050] Specifically, the first fixing piece 1 is provided with a first assembly part, and the supporting piece 4 is provided with a second assembly part, and the first assembly part and the second assembly part are detachably connected by a first fastener. Among them, the first assembly part is a first connecting plate, and the second assembly part is a second connecting plate, and the first connecting plate and the second connecting plate are both provided with threaded holes, and the first fastener is a bolt, and the first connecting plate and the second connecting plate are detachably connected by the bolt; the supporting piece 4 is a cross beam structure, specifically a square tube with a cross-sectional size of 400mm*200mm*16mm and a length of 6m. By detachably connecting the first fixing piece 1 and the supporting piece 4, the first fixing piece 1 can be hoisted to a specified position and then separated from the supporting piece 4, and the supporting piece 4 can be recycled. As a transformable implementation, the corresponding positions of the first fixing piece 1 and the supporting piece 4 can be provided with plug-in parts, and the first fixing piece 1 and the supporting piece 4 can be plug-in connected.

[0051] In one embodiment, the connecting piece 5 is provided with three, one of which has an adjustable length, which is used to adjust the angle of the supporting piece 4 under external force. By adjusting the length of the connecting piece 5 to adjust the angle of the supporting piece 4, the angle of the first fixing piece 1 can be adjusted away from the steel column and the steel beam, so that the angle of the first fixing piece 1 and the steel column and the steel beam is adapted, which is convenient for installation and is not limited by the operation space, and the adjustment is more convenient and accurate. As a transformable implementation, the connecting piece 5 can also be provided with one, two or four, and the number of settings is determined according to the length and weight of the supporting piece 4, which is not limited here. As a transformable implementation, the lengths of two connecting pieces 5 can be adjustable, or the lengths of three connecting pieces 5 can be adjustable, which is not limited here.

[0052] Specifically, as shown in FIG. 6, the first to-be-installed piece 2 and the second to-be-installed piece 3 are arranged at an angle to each other, and the first fixing piece 1 is arranged between the first to-be-installed piece 2 and the second to-be-installed piece 3. Figure 1As shown, the lifting parts 41 are provided in one-to-one correspondence with the connecting pieces 5, wherein three lifting parts 41 are provided on the support piece 4, the first lifting part is close to the first fixing piece 1, and the second lifting part and the third lifting part are sequentially provided in the direction away from the first fixing piece 1; the connecting piece 5 is provided with three, the first connecting piece is connected with the first lifting part, the length of the first connecting piece is adjustable, the second connecting piece is connected with the second lifting part, and the third connecting piece is connected with the third lifting part; when the first fixing piece 1 is assembled on the support piece 4, the first connecting piece and the third connecting piece jointly provide the support piece 4 with a pulling force to keep the center of gravity of the support piece 4 balanced; when the first fixing piece 1 is removed from the support piece 4, the second connecting piece and the third connecting piece jointly provide the support piece 4 with a pulling force to keep the center of gravity of the support piece 4 balanced. Wherein, the first connecting piece is a chain; the second connecting piece and the third connecting piece are steel wires. By adopting three lifting parts 41 and three connecting pieces 5, corresponding connecting pieces 5 can be selected for lifting according to the change of the center of gravity position, so as to facilitate quick and accurate adjustment of the angle of the support piece 4 and prevent the support piece 4 from overturning and falling during lifting, which is dangerous to the operator. As a convertible embodiment, the second connecting piece and the second lifting part can not be provided, but the length of the first connecting piece is directly adjusted to adjust the angle of the support piece 4 to change the structural center of gravity.

[0053] Wherein, when the first fixing piece 1 is assembled on the support piece 4, the center of gravity of the support piece 4 deviates to one side of the first fixing piece 1; when the first fixing piece 1 is removed from the support piece 4, the center of gravity of the support piece 4 coincides with the geometric center thereof.

[0054] In one embodiment, the length of the second connecting piece is equal to the length of the third connecting piece. By setting the length of the second connecting piece to be equal to the length of the third connecting piece, both the second connecting piece and the third connecting piece are stretched after the first fixing piece 1 is removed, so that the support piece 4 can be kept in a horizontal state, the angle of the support piece 4 can be quickly adjusted, and the support piece 4 can be prevented from overturning due to unstable center of gravity. As a convertible embodiment, the length of the second connecting piece can be slightly greater than the length of the third connecting piece, or the length of the second connecting piece can be slightly less than the length of the third connecting piece, as long as the stability of the support piece 4 during lifting can be ensured, which is not limited here.

[0055] According to the embodiment of the present application, on the other hand, a lifting method is also provided, which is applied to the lifting device described above, and includes: lifting the support piece 4 and the first fixing piece 1 to the steel column and the steel beam.

[0056] As Figure 2As shown, when the first fixing member 1 is away from the steel column and the steel beam, the length of the first connecting member is adjusted so that the first connecting member and the third connecting member jointly provide the pulling force for the support member 4, the second connecting member is in a relaxed state, and the support member 4 is adjusted to a horizontal state for hoisting. By adjusting the support member 4 to a horizontal state for hoisting, it can be prevented that the support member 4 is overturned during hoisting to cause danger.

[0057] As shown in the drawings, Figure 3 In one embodiment, before hoisting the first fixing member 1 between the steel column and the steel beam, it further includes adjusting the angle of the support member 4 so that the placement angle of the first fixing member 1 is adapted to the assembly angle of the steel column. As a convertible implementation, it can also be that, according to the end angle of the steel column, when the first fixing member 1 is fixedly connected to the support member 4, that is, the angle of the first fixing member 1 is adjusted to adapt to the end angle of the steel column, then the first fixing member 1 can be directly fixed and installed after being hoisted to the specified position, without the need to adjust the angle of the support member 4.

[0058] As shown in the drawings, Figures 4-5 In one embodiment, after hoisting the first fixing member 1 between the steel column and the steel beam, it further includes separating the first fixing member 1 from the support member 4 after the first fixing member 1 is fixedly connected to the steel column; and removing the hoisting device. As a convertible implementation, it can also be that the first fixing member 1 is fixedly connected to the end of the steel beam, and the specific fixing position is determined according to the actual situation, which is not limited here.

[0059] As shown in the drawings, Figures 2-5 The second fixing member 6 is fixedly connected to the end of the steel beam close to the steel column, and the second fixing member 6 is oppositely arranged with the first fixing member 1. The first fixing member 1 is provided with a first mounting hole 11, and the second fixing member 6 is provided with a second mounting hole 61, and a second fastener is arranged in the first mounting hole 11 and the second mounting hole 61 for fixation. The second fastener is a pin shaft, and the second fixing member 6 is a second ear plate. As a convertible implementation, the second fixing member 6 can be fixedly connected to the end of the steel column close to the steel beam, and at this time, the first fixing member 1 is fixedly connected to the end of the steel beam.

[0060] As shown in the drawings, Figure 4 In one embodiment, after separating the first fixing member 1 from the support member 4, it further includes adjusting the angle of the support member 4 so that the support member 4 is in a horizontal state. By adjusting the support member 4 to a horizontal state for hoisting, it can be prevented that the support member 4 is overturned during hoisting to cause danger.

[0061] In one embodiment, the angle of the support 4 is adjusted to be horizontal by removing the first connecting member and allowing the second and third connecting members to provide tension to the support 4 to make the support 4 horizontal. Specifically, the length of the first connecting member is adjusted first, and then the first connecting member is removed after the second connecting member is stretched by tension, so that the second and third connecting members provide tension to the support 4. Since the second and third connecting members have the same length, the support 4 is in a horizontal state at this time.

[0062] Although the embodiments of the present application have been described with reference to the accompanying drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes are intended to fall within the scope of the appended claims.
