Description

Technical Field

[0001] This application relates to the technical field of steel structure hoisting, and particularly relates to a steel structure lifting tool and a hook. Background Art

[0002] When constructing a steel structure building, usually the main steel columns are hoisted and fixed first. After the installation of the main steel columns is completed, the main steel beams between two main steel columns are hoisted.

[0003] During the hoisting process of the main steel beam, in order to speed up the construction progress, usually workers will put a lifting rope on both sides of the main steel beam. After the hook of the crane hooks the lifting rope, the hoisting starts. However, during this process, if the center of gravity of the main steel beam shifts, the main steel beam may slip out of the lifting rope, making the safety during the hoisting process unable to be guaranteed. Summary of the Invention

[0004] In order to improve the problem that the steel structure may slip out of the lifting rope during the steel structure hoisting process, this application provides a steel structure lifting tool and a hook.

[0005] This application provides a steel structure lifting tool and a hook, adopting the following technical solutions:

[0006] A steel structure lifting tool, including a central plate;

[0007] A locking assembly, arranged on one side of the central plate, for detachably connecting with a hook;

[0008] A hoisting assembly, arranged on the side of the central plate away from the locking assembly, for detachably connecting with a steel member;

[0009] A pulling rope, one end of the pulling rope is connected to the central plate, and can be used to release the locking between the hoisting assembly and the steel member.

[0010] By adopting the above technical solutions, before hoisting the steel member, the lifting tool is fixedly arranged on the steel member through the hoisting assembly, and the hook is fixedly connected with the locking assembly. During hoisting, since the steel member is fixedly connected with the hoisting assembly, and the hoisting assembly is fixedly connected with the locking assembly, the steel member is not easy to slip during the hoisting process, improving the safety of hoisting the steel member; after hoisting is completed, the pulling rope is used to release the locking between the hoisting assembly and the steel member, facilitating the recycling of the lifting tool.

[0011] Optionally, the locking assembly includes two side plates vertically and fixedly arranged on the central plate. The two side plates are parallel to each other. A limiting plate is fixedly arranged on the side of the side plate away from the central plate. The limiting plate is perpendicular to the side plate. A clamping area for inserting the hook is provided on the side plate.

[0012] By adopting the above technical solution, when hoisting steel members, the hook is placed in the gap between the limit plate and the center plate, and the hook is inserted into the clamping area, so that the connection and fixation between the hook and the lifting tool can be realized. The setting of the clamping area can limit the position of the hook during the hoisting process.

[0013] Optionally, the clamping area is arranged on the surface of the limit plate close to the center plate. The clamping area includes an inclined slot and a clamping hole opened on the limit plate, and the inclined slot and the clamping hole are communicated.

[0014] By adopting the above technical solution, when using the lifting tool to hoist steel members, the hook is inserted into the inclined slot and the clamping hole, so that the position of the hook is limited. During the hoisting process, the hook is not easy to shift, enhancing the stability and safety during the hoisting process. After the hoisting is completed, the lifting rope above the hook is loosened, and the hook is separated from the lifting tool, which is convenient for removing the hook from the lifting tool.

[0015] Optionally, the hoisting assembly includes two parallel sliding plates, and a bearing plate vertically and fixedly arranged on the opposite sides of the two sliding plates. The bearing plate is arranged in parallel and at intervals with the center plate;

[0016] The hoisting assembly further includes an adjusting member for adjusting the position of the sliding plate relative to the center plate.

[0017] By adopting the above technical solution, during the hoisting process of steel members, the lifting tool is installed on the steel member, and the wing plate of the steel member is placed between the bearing plate and the center plate. The position of the sliding plate is adjusted by the adjusting member, so that the wing plate of the steel member is restricted between the bearing plate and the center plate to complete the connection and fixation between the lifting tool and the steel member.

[0018] Optionally, a sliding track is opened on the side wall of the center plate, and a plurality of fixing grooves are also arranged at intervals along the length direction of the sliding track in the center plate. The fixing grooves are communicated with the sliding track. The adjusting member includes a sliding bar slidably arranged in the sliding track. The sliding bar can drive the sliding plate to move and is clamped in the fixing groove.

[0019] By adopting the above technical solution, the sliding plate can be adjusted along the length direction of the sliding track, and when the sliding bar slides to a suitable position, the sliding bar can be clamped in the fixing groove to fix the position of the sliding bar relative to the center plate.

[0020] Optionally, the hoisting assembly further includes an adjusting block detachably connected to the sliding plate. The adjusting block is arranged between the sliding bar and the sliding plate. A lifting groove for the sliding plate to slide is opened in the adjusting block, and a plurality of clamping grooves are arranged in parallel and at intervals on the side wall of the lifting groove;

[0021] A rotating rod is slidably arranged in the sliding plate. One end of the rotating rod is fixedly provided with a rotating head, and the rotating head can be rotatably clamped into the clamping groove.

[0022] By adopting the above technical solution, the skateboard can be adjusted up and down along the set path of the lifting groove. Rotate the rotating head so that the rotating head is located in the lifting groove. At this time, the skateboard can slide along the lifting groove. After adjusting the skateboard to an appropriate position, rotate the rotating head so that the rotating head is clamped into the clamping groove. At this time, the position of the skateboard is fixed.

[0023] Optionally, it further includes a power component. The bearing plate is electrically connected to the power component, and the bearing plate has magnetism after being powered on. The power component includes a power source fixedly arranged on the central plate and a switch for turning on and off the power source. The pull rope can close the switch.

[0024] By adopting the above technical solution, when hoisting, turn on the switch to make the bearing plate powered on. At this time, the bearing plate and the steel member are attracted to each other by magnetic force. During the hoisting process, the steel member is tightly attracted to the bearing plate, making it difficult for the steel member to slip; when the hoisting of the steel member is completed, pull the pull rope to close the switch, making the bearing plate demagnetized. At this time, there is no attracting magnetic force between the lifting tool and the steel member. Pull the pull rope to make the lifting tool slide relative to the steel member until the lifting tool is removed.

[0025] On the other hand, a hook used in cooperation with the above lifting tool provided by the present application adopts the following technical solution:

[0026] A hook includes a middle column and two inverted hooks symmetrically arranged along the middle column. One end of the middle column is fixedly connected to the crane, and the other end is fixedly connected to one end of the two inverted hooks at the same time. The inverted hooks are used to abut against the side wall of the inclined groove.

[0027] By adopting the above technical solution, the hook is located in the space between the limit plate and the central plate during the hoisting process. The setting of the inverted hooks enables the hook to be clamped in the inclined groove, making the hook stably connected to the lifting tool during the hoisting process. And the inverted hooks are clamped in the inclined groove, making it difficult for the hook to slip and deviate during the hoisting process.

[0028] Optionally, a clamping column is vertically fixed at one end of the two inverted hooks away from the end of the middle column. The clamping column is used to be clamped into the clamping hole.

[0029] By adopting the above technical solution, when hoisting a steel member, the clamping column is clamped into the clamping hole, making the connection between the hook and the lifting tool more stable. It is more difficult for the hook to slip relative to the lifting tool during the hoisting process, making the safety of the hoisting process higher.

[0030] To sum up, the present application includes at least one of the following beneficial effects:

[0031] 1. When hoisting a steel member, due to the magnetic suction force of the bearing plate, the steel member can be stably connected to the lifting tool, reducing the possibility of the steel member slipping from the lifting tool;

[0032] 2. The hook is clamped in the clamping area, so that when hoisting steel structures, the hook can be firmly connected to the lifting tool. After the hoisting is completed, loosening the lifting rope above the hook can realize the connection between the hook and the lifting tool, making it more convenient to remove the hook.

[0033] 3. A pulling rope is arranged on the lifting tool. On the one hand, it is convenient for construction workers to control the opening and closing of the power source, so as to control the magnetic connection between the lifting tool and the hook. On the other hand, setting the pulling rope makes it more convenient to remove and recycle the lifting tool from the steel member. Description of the Drawings

Detailed Description of the Embodiment

[0040] The following further describes the present application in detail Figures 1-5 with reference to the attached drawings.

[0041] A steel structure lifting tool and a hook disclosed in the embodiment of the present application.

[0042] Referring to Figure 1 , a steel structure lifting tool includes a central plate 1, a locking assembly 2 and a hoisting assembly 3. The central plate 1 is made of steel of Q345 material. The locking assembly 2 is fixedly arranged on the plate surface of the central plate 1 and is used for detachably connecting with the hook 7. The hoisting assembly 3 is slidably arranged on the plate surface of the central plate 1 away from the locking assembly 2 and is used for connecting and fixing with the steel member.

[0043] Refer to Figure 1 , the locking assembly 2 includes two side plates 21 parallel to each other. The side plates 21 are perpendicularly and fixedly connected to the central plate 1. One end of the side plate 21 away from the central plate 1 is fixedly connected with a limiting plate 22. The limiting plate 22 is vertically arranged on one side where the two side plates 21 face each other, and is arranged parallel and spaced apart from the central plate 1. The limiting plates 22 fixedly connected to the two side plates 21 are in the same plane, and there is a gap between the two limiting plates 22.

[0044] Refer to Figure 1 and Figure 2 , clamping areas are arranged on the side walls of the two limiting plates 22 close to the central plate 1. The limiting plate 22 is provided with an inclined slot 221 and a clamping hole 222 in the clamping area. The inner wall of the inclined slot 221 facing the central plate 1 is an inclined surface, and gradually approaches the central plate 1 in the direction away from the side plate 21. The clamping hole 222 is arranged at one end of the inclined slot 221 close to the side plate 21. The clamping hole 222 is perpendicularly opened with respect to the plate surface of the limiting plate 22, and the clamping hole 222 communicates with the inclined slot 221.

[0045] Refer to Figure 1 , the hoisting assembly 3 includes two parallel sliding plates 31. The sliding plates 31 are arranged perpendicular to the plate surface of the central plate 1. One end of the sliding plate 31 away from the central plate 1 is fixedly provided with a bearing plate 32. The bearing plate 32 is arranged on the side walls where the two sliding plates 31 face each other and is perpendicular to the plate surface of the sliding plate 31. The two bearing plates 32 are arranged coplanarly, and the bearing plate 32 is parallel and spaced apart from the central plate 1. There is a gap between the two bearing plates 32. The bearing plate 32 is all or partially an electromagnet structure that can have magnetism after being electrified.

[0046] Refer to Figure 3 and Figure 4 , the hoisting assembly 3 further includes an adjusting member, and the adjusting member enables the sliding plate 31 to slide horizontally along the central plate 1. A sliding track 11 is opened on one side of the central plate 1 away from the locking assembly 2. The sliding track 11 is arranged along the connection line direction between the two sliding plates 31, and a plurality of rectangular fixing slots 12 are opened on the side wall of the sliding track 11 in parallel and at intervals. The adjusting member is specifically a sliding bar 4 arranged in the sliding track 11. The cross section of the sliding bar 4 is rectangular. A clamping block 41 is fixedly arranged on the sliding bar 4, and the clamping block 41 can be clamped into the fixing slot 12. When it is necessary to adjust the horizontal position of the sliding plate 31, lift the sliding plate 31 upward so that the clamping block 41 on the sliding plate 31 is separated from the fixing slot 12, move the sliding bar 4 in the sliding track 11, and after adjusting to a suitable position, clamp the clamping block 41 into the fixing slot 12 to fix the position of the sliding plate 31 relative to the central plate 1.

[0047] Refer to Figure 3, the two sliding plates 31 can also adjust their positions perpendicular to the center plate 1. Specifically, the hoisting assembly 3 further includes two adjusting blocks 33. One adjusting block 33 is located between one sliding plate 31 and the sliding bar 4 and is fixedly connected to the sliding bar 4; the other adjusting block 33 is located between the other sliding plate 31 and the center plate 1 and is fixedly connected to the center plate 1. A lifting groove 331 is formed in the adjusting block 33, and the sliding plate 31 can slide along the lifting groove 331. A plurality of groups of clamping grooves 332 are arranged in parallel and at intervals on the side wall of the lifting groove 331. Each group of clamping grooves 332 includes two clamping grooves 332 symmetrically arranged along the path direction of the lifting groove 331. A circular hole is penetrated in the sliding plate 31, and a rotating rod 311 is rotatably arranged in the circular hole. One end of the rotating rod 311 is fixedly provided with a rotating head 312. When the sliding plate 31 needs to be adjusted up and down, the rotating rod 311 is pulled out so that the rotating head 312 is located outside the lifting groove 331. The sliding plate 31 is slid to a suitable position, and the rotating rod 311 is pushed so that the rotating head 312 is clamped in a group of clamping grooves 332. At this time, the position of the sliding plate 31 relative to the center plate 1 is fixed.

[0048] Referring to Figure 1 and Figure 5 , after the lifting appliance is fixed on the steel member, the steel member is hoisted. The lifting appliance of the present application further includes a power assembly 5. The power assembly 5 is fixedly arranged on the center plate 1. The power assembly 5 includes a power source 51 and a switch 52. The power source 51 can be a power source capable of storing electricity. The power source is turned on and off through the switch 52. The power assembly 5 is electrically connected to the bearing plate 32. A pull rope 6 is tied to the switch 52. At the same time, a pull rope 6 is also tied to the center plate 1. The ends of the two pull ropes 6 away from the lifting appliance are tied to the end of the steel member.

[0049] Referring to Figure 1 and Figure 5 , when the steel member is hoisted, the switch 52 is turned on so that the bearing plate 32 is energized and has magnetism. During the hoisting process, the bearing plate 32 is magnetically attracted to the steel member, so that the steel member is not easily slipped off the lifting appliance during the hoisting process; after the hoisting is completed, the construction worker can untie the pull rope 6 at the end of the steel member and pull the pull rope 6 to turn off the switch 52. At this time, the bearing plate 32 releases the magnetic attraction force with the steel member. At the same time, the two pull ropes 6 are pulled so that the lifting appliance slides along the steel member until the lifting appliance is removed.

[0050] The embodiment of the present application also provides a hook, which is used in cooperation with the steel structure lifting appliance in the embodiment of the present application. Referring to Figure 2 and Figure 3, including a central column 71 and two barbs 72 symmetrically arranged along the central column 71. Both the barbs 72 and the central column 71 are made of steel of Q345 specification. One end of each of the two barbs 72 is fixedly connected to the end of the central column 71, and an angle is formed between the barb 72 and the central column 71. A clamping column 73 is fixedly provided at the end of the barb 72 far from the central column 71. One end of the clamping column 73 is fixedly connected to the end of the barb 72, and the clamping column 73 is vertically arranged. When lifting a steel member by using a lifting hook 7, the clamping column 73 can be inserted into the clamping hole 222.

[0051] The implementation principle of a steel structure lifting tool and a lifting hook in an embodiment of the present application is as follows: Before hoisting a steel member, install two lifting tools on the steel member first. Set the flange of the steel member between the bearing plate 32 and the central plate 1. Use the adjusting member to adjust the horizontal position of a sliding plate 31 so that the flange of the steel member will not slip from the gap between the two bearing plates 32 and the flange of the steel member can be as close to the sliding plate 31 as possible. Then continue to adjust the vertical positions of the two sliding plates 31 so that the flange of the steel member is as close to the central plate 1 and the bearing plate 32 as possible. After the positions of the sliding plates 31 are adjusted, tie the ends of the two pulling ropes 6 on the lifting tool far from the lifting tool to the end of the steel member. After the lifting tool is installed, hang the lifting hook 7 on the lifting tool, and insert the barb 72 and the clamping column 73 of the lifting hook 7 into the inclined slot 221 and the clamping hole 222 respectively. After the lifting hook 7 is installed, turn on the switch 52 so that the bearing plate 32 has magnetism or has magnetism locally. At this time, the bearing plate 32 and the steel member are magnetically attracted to each other, and use a crane to hoist the steel member.

[0052] After the steel member is hoisted, drive the lifting hook 7 to move towards the central plate 1. At this time, the lifting hook 7 disengages from the inclined slot 221 and the clamping hole 222 and is between the central plate 1 and the limiting plate 22. Horizontally move the lifting hook 7 to realize the separation between the lifting hook 7 and the lifting tool. The construction worker unties the connection between the two ends of the steel member and the pulling rope 6, and pulls the pulling rope 6 connected to the switch 52 to close the switch 52. At this time, the bearing plate 32 is demagnetized, and there is no magnetic connection between the steel member and the lifting tool. At the same time, pull the two pulling ropes 6 to make the lifting tool slide along the steel member until the lifting tool is removed from the steel member.

[0053] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
