Description

Technical Field

[0001] The invention relates to the technical field of steel structure construction, and in particular to a hoisting device and a hoisting method. Background Art

[0002] In large-span space structures such as terminal buildings and gymnasiums, pins are usually used to connect the steel beams and steel columns with the lugs on the steel beams and steel columns. The lugs are usually welded on the ground and then hoisted to the predetermined position together with the steel beams and steel columns. However, after the steel beams and steel columns are installed, due to installation errors, the position of the lug mounting holes will be misaligned, resulting in the pins being unable to be smoothly inserted into the mounting holes.

[0003] In order to avoid the above situation, in the prior art, only the ear plates of the steel beams are welded on the ground, while the ear plates of the steel columns are repositioned according to the actual installation positions of the steel beams and steel columns, and welded at high altitude. Due to the large size and heavy weight of the ear plates, tower cranes are usually used to hoist the ear plates; however, due to the obstruction of the steel beams, the tower cranes cannot directly hoist the ear plates to the top of the steel columns. Therefore, during the specific hoisting, the ear plates are usually first hoisted to the vicinity of the installation position by a tower crane, and the operator then manually moves the ear plates between the steel beams and the steel columns, and finally welds and fixes them. The above method of installing the ear plates is subject to the limitation of the operating space for high-altitude operations, and the installation is difficult, the construction efficiency is low, and the safety risks of the operators are increased. Summary of the invention

[0004] In view of this, the present invention provides a hoisting device and a hoisting method to solve the problem that the ear plate is hoisted to the vicinity of the installation position by a tower crane and then installed by cooperating with a fall chain, which is restricted by the operating space limitation of high-altitude operations, resulting in great installation difficulty, low construction efficiency and increased safety risks for operators.

[0005] In a first aspect, the present invention provides a hoisting device for hoisting a first fixing member between a first member to be installed and a second member to be installed, wherein the first member to be installed and the second member to be installed are arranged at an angle to each other, and the hoisting device comprises:

[0006] Lifting parts;

[0007] A support member, the first fixing member is detachably connected to the support member, the first fixing member is arranged near the end of the support member, and the size of the support member is larger than the size of the first fixing member along the direction parallel to the extension length of the support member, and the size of the support member is smaller than the size of the first fixing member along the direction perpendicular to the extension length of the support member, and a hoisting portion is arranged on the support member;

[0008] A connecting member, one end of which is connected to the lifting part and the other end of which is connected to the lifting member, is used to maintain the center of gravity balance of the supporting member.

[0009] Beneficial effect: by setting the first fixing part close to the end of the supporting part, during hoisting, the hoisting part can hoist the first fixing part between the first part to be installed and the second part to be installed by hoisting the supporting part, and because the size of the supporting part is larger than the size of the first fixing part along the extension length direction parallel to the supporting part, when the hoisting part hoists the supporting part to the vicinity of the installation position, the first fixing part can be located between the first part to be installed and the second part to be installed. At the same time, along the extension length direction perpendicular to the supporting part, the size of the supporting part is smaller than the size of the first fixing part, so that the supporting part will not interfere with the installation of the first fixing part between the first part to be installed and the second part to be installed. The hoisting device in this embodiment can prevent the connecting part from being blocked by the first part to be installed or the second part to be installed, and can directly hoist the first fixing part to the specified position without being restricted by the operating space, thereby reducing the difficulty of installation, improving construction efficiency, reducing the safety risks of operators, and reducing the cost of safety protection investment.

[0010] In an optional embodiment, at least two connecting members are provided, and at least one of the connecting members has an adjustable length, so as to adjust the angle of the supporting member under the action of an external force.

[0011] Beneficial effect: By adjusting the length of the connecting part to adjust the angle of the supporting part, the angle of the first fixing part can be adjusted at a position far away from the first part to be installed and the second part to be installed, so that the angle of the first fixing part is matched with the first part to be installed and the second part to be installed, which is convenient for installation, not limited by the operating space, and the adjustment is more convenient and accurate.

[0012] In an optional embodiment, the support member is provided with three lifting parts, the first lifting part is close to the first fixing member, and the second lifting part and the third lifting part are sequentially provided in a direction away from the first fixing member;

[0014] When the first fixing member is assembled on the supporting member, the first connecting member and the third connecting member jointly provide a pulling force for the supporting member to keep the center of gravity of the supporting member balanced;

[0015] When the first fixing member is removed from the supporting member, the second connecting member and the third connecting member jointly provide a pulling force for the supporting member to keep the center of gravity of the supporting member balanced.

[0016] Beneficial effect: By adopting three lifting parts and three connecting parts, the corresponding connecting parts can be selected for lifting according to the change of the center of gravity position, which is convenient for quickly and accurately adjusting the angle of the support part and preventing the support part from flipping and falling during the lifting process, causing danger to the operator.

[0018] And / or, the second connecting member and the third connecting member are steel wire ropes;

[0019] And / or, the length of the second connecting member is equal to the length of the third connecting member.

[0020] Beneficial effect: By setting the length of the second connecting member to be equal to the length of the third connecting member, after the first fixing member is removed, the second connecting member and the third connecting member can be stretched, thereby ensuring that the support member is in a horizontal state, and the angle of the support member can be quickly adjusted to prevent the support member from flipping over due to an unstable center of gravity.

[0021] In an optional embodiment, a first assembly portion is provided on the first fixing member, and a second assembly portion is provided on the supporting member, and the first assembly portion and the second assembly portion are detachably connected via a first fastener.

[0024] The supporting member and the first fixing member are hoisted between the first member to be installed and the second member to be installed.

[0025] Beneficial effect: Since the hoisting method includes the hoisting device, it has the same effect as the hoisting device and will not be described in detail herein.

[0026] In an optional implementation, before hoisting the first fixing member between the first member to be installed and the second member to be installed, the method further includes:

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0045] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0046] According to an embodiment of the present invention, on the one hand, a lifting device is provided for lifting a first fixing member 1 between a first member to be installed 2 and a second member to be installed 3, wherein the first member to be installed 2 and the second member to be installed 3 are arranged at an angle to each other, and the lifting device comprises: a lifting member; a support member 4, to which the first fixing member 1 is detachably connected, the first fixing member 1 is arranged near the end of the support member 4, and along a direction parallel to the extension length of the support member 4, the size of the support member 4 is larger than the size of the first fixing member 1, and along a direction perpendicular to the extension length of the support member 4, the size of the support member 4 is smaller than the size of the first fixing member 1, and a lifting portion 41 is provided on the support member 4; a connecting member 5, one end of which is connected to the lifting portion 41, and the other end is connected to the lifting member, for maintaining the center of gravity balance of the support member 4.

[0047] By arranging the first fixing member 1 close to the end of the support member 4, during lifting, the lifting member can lift the first fixing member 1 between the first to-be-installed member 2 and the second to-be-installed member 3 by lifting the support member 4, and because the size of the support member 4 is larger than the size of the first fixing member 1 along the extension length direction parallel to the support member 4, when the lifting member lifts the support member 4 to the vicinity of the installation position, the first fixing member 1 can be located between the first to-be-installed member 2 and the second to-be-installed member 3. At the same time, along the extension length direction perpendicular to the support member 4, the size of the support member 4 is smaller than the size of the first fixing member 1, so that the support member 4 will not interfere with the installation of the first fixing member 1 between the first to-be-installed member 2 and the second to-be-installed member 3. The lifting device in this embodiment can prevent the connecting member 5 from being blocked by the first to-be-installed member 2 or the second to-be-installed member 3, and can directly lift the first fixing member 1 to the specified position without being restricted by the operating space, thereby reducing the difficulty of installation, improving construction efficiency, reducing the safety risks of operators, and reducing the cost of safety protection investment.

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

[0049] In one embodiment, the first fixing member 1 is a first ear plate, the first member to be installed 2 is a steel column, and the second member to be installed 3 is a steel beam. As a convertible embodiment, the first fixing member 1 can also be a flat plate structure, which is welded and fixed to the first member to be installed 2 and the second member to be installed 3. The first fixing member 1 can also be other connection structures, as long as the ends of the first member to be installed 2 and the second member to be installed 3 can be connected. As a convertible embodiment, the first member to be installed 2 and the second member to be installed 3 can also be other structures arranged at an angle to each other, and there are no excessive restrictions here.

[0050] Specifically, the first fixing member 1 is provided with a first assembly part, and the support member 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. 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 bolts; the support member 4 is a 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 member 1 and the support member 4, it is convenient to separate the first fixing member 1 from the support member 4 after hoisting it to a designated position, and the support member 4 can be recycled. As a convertible embodiment, it can also be that the corresponding positions of the first fixing member 1 and the support member 4 are both provided with plug-in parts, and the first fixing member 1 and the support member 4 are plug-in connected.

[0051] In one embodiment, three connectors 5 are provided, and the length of one connector 5 is adjustable, and is used to adjust the angle of the support member 4 under the action of an external force. By adjusting the length of the connector 5 to adjust the angle of the support member 4, the angle of the first fixing member 1 can be adjusted at a position away from the steel column and the steel beam, so that the first fixing member 1 is adapted to the angle of the steel column and the steel beam, which is convenient for installation, is not limited by the operating space, and is more convenient and accurate to adjust. As a convertible embodiment, the connector 5 can also be provided with one, two or four connectors, and the number of connectors provided is determined according to the length and weight of the support member 4, and no excessive restrictions are made here. As a convertible embodiment, the lengths of two connectors 5 can be adjusted, or the lengths of all three connectors 5 can be adjusted, and no excessive restrictions are made here.

[0052] Specifically, Figure 1As shown, the hoisting parts 41 and the connecting parts 5 are arranged one by one, wherein the support member 4 is provided with three hoisting parts 41, the first hoisting part is close to the first fixing member 1, and the second hoisting part and the third hoisting part are sequentially arranged in the direction away from the first fixing member 1; there are three connecting parts 5, the first connecting part is connected to the first hoisting part, and the length of the first connecting part is adjustable, the second connecting part is connected to the second hoisting part, and the third connecting part is connected to the third hoisting part; when the first fixing member 1 is assembled on the support member 4, the first connecting part and the third connecting part jointly provide tension for the support member 4 to keep the center of gravity of the support member 4 balanced; when the first fixing member 1 is removed from the support member 4, the second connecting part and the third connecting part jointly provide tension for the support member 4 to keep the center of gravity of the support member 4 balanced. Among them, the first connecting part is a fall chain; the second connecting part and the third connecting part are steel wire ropes. By using three hoisting parts 41 and three connecting members 5, the corresponding connecting member 5 can be selected for hoisting according to the change of the center of gravity position, so as to facilitate the rapid and accurate adjustment of the angle of the support member 4, and prevent the support member 4 from flipping and falling during the hoisting process, which may cause danger to the operator. As a convertible embodiment, the second connecting member and the second hoisting part may not be provided, but the angle of the support member 4 may be adjusted directly by adjusting the length of the first connecting member to change the center of gravity of the structure.

[0053] When the first fixing member 1 is assembled on the supporting member 4, the center of gravity of the supporting member 4 is biased toward one side of the first fixing member 1; when the first fixing member 1 is removed from the supporting member 4, the center of gravity of the supporting member 4 coincides with its geometric center.

[0054] In one embodiment, the length of the second connecting member is equal to the length of the third connecting member. By setting the length of the second connecting member to be equal to the length of the third connecting member, after the first fixing member 1 is removed, the second connecting member and the third connecting member can be stretched, so that the support member 4 can be kept in a horizontal state, and the angle of the support member 4 can be quickly adjusted to prevent the support member 4 from flipping due to an unstable center of gravity. As a convertible embodiment, the length of the second connecting member can be slightly greater than the length of the third connecting member, or the length of the second connecting member can be slightly less than the length of the third connecting member, as long as the stability of the support member 4 during the lifting process can be guaranteed, and no excessive restrictions are made here.

[0055] According to an embodiment of the present invention, on the other hand, a hoisting method is provided, which is applied to the above-mentioned hoisting device, including: hoisting a support member 4 and a first fixing member 1 between a steel column and a steel beam.

[0056] like 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 a pulling force for the supporting member 4, the second connecting member is in a relaxed state, and the supporting member 4 is adjusted to a horizontal state for hoisting. By adjusting the supporting member 4 to a horizontal state for hoisting, it is possible to prevent the supporting member 4 from turning over during the hoisting process to cause danger.

[0057] like Figure 3 As shown, in one embodiment, before hoisting the first fixing member 1 between the steel column and the steel beam, it also includes: adjusting the angle of the support member 4 so that the placement angle of the first fixing member 1 matches 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 match 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 adjusting the angle of the support member 4.

[0058] like Figure 4-Figure 5 As shown, in one embodiment, after hoisting the first fixing member 1 between the steel column and the steel beam, it also includes: after the first fixing member 1 is fixedly connected to the steel column, the first fixing member 1 is separated from the support member 4; and the hoisting device is removed. As a convertible implementation, the first fixing member 1 can also be fixedly connected to the end of the steel beam. The specific fixing position is determined according to the actual situation, and no excessive restrictions are made here.

[0059] like Figure 2-Figure 5 As shown, the end of the steel beam close to the steel column is fixedly connected with a second fixing member 6, and the second fixing member 6 is arranged opposite to 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. The second fastener is inserted into the first mounting hole 11 and the second mounting hole 61 for fixing. Among them, the second fastener is a pin, and the second fixing member 6 is a second ear plate. As a convertible embodiment, it is also possible that the end of the steel column close to the steel beam is fixedly connected with the second fixing member 6, and at this time, the first fixing member 1 is fixedly connected to the end of the steel beam.

[0060] like Figure 4 As shown, in one embodiment, after separating the first fixing member 1 from the supporting member 4, the method further includes: adjusting the angle of the supporting member 4 so that the supporting member 4 is in a horizontal state. By adjusting the supporting member 4 to a horizontal state for hoisting, the supporting member 4 can be prevented from turning over during the hoisting process to cause danger.

[0061] In one embodiment, adjusting the angle of the support member 4 so that the support member 4 is in a horizontal state includes: removing the first connecting member so that the second connecting member and the third connecting member jointly provide a pulling force for the support member 4 so that the support member 4 is in a horizontal state. Specifically, the length of the first connecting member is adjusted first, and the first connecting member is removed after the second connecting member is stretched, so that the second connecting member and the third connecting member jointly provide a pulling force for the support member 4. Since the second connecting member and the third connecting member have the same length, the support member 4 is in a horizontal state at this time.

[0062] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
