Description

Technical Field

[0001] The utility model relates to the technical field of steel structure hoisting, in particular to a steel structure hoisting device. Background Technique

[0002] The steel structure hoisting device is an auxiliary device for steel structure hoisting. During the process of hoisting the steel structure, both ends of the hoisting rope are connected to the steel structure member by bolts and screw holes. After the hoisting rope is connected, it is then hung on the hook, and the hoisting of the steel structure member is realized by the lifting of the hook by an external traction device. During the hoisting process, after both ends of the hoisting rope are connected to the steel structure member, the opening and closing degree of the hoisting rope is relatively fixed and cannot be adjusted. When the opening and closing degree of the hoisting rope is too large, the tension of the hoisting rope will increase, which may cause the hoisting rope to break or the hoisted object to become unstable. When the opening and closing degree of the hoisting rope is too small, although the tension of the hoisting rope will decrease, the stability of the hoisted object will also be affected, and it may swing or rotate, affecting the use of the hoisting device.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , a steel structure hoisting device provided by the present utility model includes a lifting rope 101 and a hook 102. The lifting rope 101 is hung on the hook 102, and both ends of the lifting rope 101 are fixedly connected to the steel structure member 2 by bolts. It further includes a mounting frame 3 sleeved outside the lifting rope 101 after hanging. Both ends of the lifting rope 101 pass through the mounting frame 3, and two groups of limiting components for limiting the movement and adjustment of the mounting frame 3 on the lifting rope 101 are arranged on the mounting frame 3;

[0020] The limiting component includes a limiting slot 401 opened on the inner wall of the mounting frame 3. A limiting plate 402 is connected inside the mounting frame 3 through a connecting component. One end of the lifting rope 101 passes through between the limiting slot 401 and the limiting plate 402. An arc-shaped groove 403 for abutting against the outer side of the lifting rope 101 is opened on the limiting plate 402. A transmission component for driving the limiting plate 402 is arranged on the mounting frame 3;

[0021] It should be noted here that during the hoisting process, after connecting both ends of the lifting rope 101 to the steel structure member 2, the mounting frame 3 is slid on the lifting rope 101 and limited. Through the sliding and limiting of the mounting frame 3, the mounting frame 3 squeezes the lifting rope 101 to contract, realizing the adjustment of the opening degree of the lifting rope 101 after connection, so that the lifting rope 101 has an appropriate opening degree for hoisting operation, facilitating the stable hoisting operation of the hoisting device.

[0022] The connecting component includes a fixing plate 501 fixed inside the mounting frame 3. A plurality of first sleeves 502 are fixed on the fixing plate 501. A first sliding rod 503 is slidably connected to the first sleeve 502. One end of the first sliding rod 503 is fixed to the limiting plate 402;

[0023] It should be noted here that the movement of the limiting plate 402 after being stressed is guided through the first sleeve 502 and the first sliding rod 503.

[0024] The transmission assembly includes an installation groove 601 formed on one side of the installation frame 3. The installation groove 601 is communicated with the interior of the installation frame 3. A transmission plate 602 is connected to the installation groove 601 through a guiding assembly. Two symmetrically arranged inclined grooves 603 are formed on the transmission plate 602. A transmission pin 604 is slidably connected to the two inclined grooves 603. The two transmission pins 604 are respectively fixed to one side of the limiting plates 402 on the two limiting assemblies. A pushing assembly for pushing the transmission plate 602 is arranged on the installation frame 3;

[0025] It should be noted here that: through the pushing assembly and the guiding assembly, the transmission plate 602 moves downward after being stressed. During the downward movement of the transmission plate 602, through the interaction between the two groups of inclined grooves 603 and the two groups of transmission pins 604, the two limiting plates 402 are respectively driven to move towards the two limiting card slots 401. During the movement, through the extrusion effect, the two sides of the lifting rope 101 are respectively abutted against the limiting card slots 401 and the arc-shaped grooves 403 on the limiting plates 402, so that the installation frame 3 after sliding adjustment is limited and fixed on the lifting rope 101.

[0026] The pushing assembly includes a threaded sleeve 801 fixed on the installation frame 3. A threaded rod 802 is in threaded engagement with the threaded sleeve 801. One end of the threaded rod 802 is rotatably connected to the upper end of the transmission plate 602;

[0027] It should be noted here that: when the threaded rod 802 is driven to rotate, during the rotation of the threaded rod 802, the transmission plate 602 is driven to move through the meshing transmission between the threaded rod 802 and the threaded sleeve 801.

[0028] A driving pin 803 for driving the threaded rod 802 is fixed to one end of the threaded rod 802;

[0029] It should be noted here that: through the driving pin 803, it is convenient to drive the threaded rod 802.

[0030] The guiding assembly includes a plurality of second sleeves 701 fixed inside the installation frame 3. A second sliding rod 702 is slidably connected to each second sleeve 701. One end of the second sliding rod 702 is fixed to the transmission plate 602;

[0031] It should be noted here that: through the plurality of second sleeves 701 and the second sliding rods 702, the movement of the transmission plate 602 after being stressed is guided.

[0032] Working principle: During the hoisting operation of the steel structure member 2 by the hoisting device, both ends of the hoisting rope 101 are connected to the corresponding positions of the steel structure member 2 in the way of bolts and screw holes. After the connection is completed, the hoisting rope 101 is hung on the hook 102. After the hanging is completed, the hook 102 is tractioned to rise and move by an external traction device to complete the hoisting operation of the steel structure member 2;

[0033] During the hoisting process, after connecting both ends of the hoisting rope 101 to the steel structure member 2, the installation frame 3 slides on the hoisting rope 101. Through the sliding of the installation frame 3, the installation frame 3 squeezes and contracts the hoisting rope 101 to adjust the opening and closing degree of the hoisting rope 101 after connection, so that the hoisting rope 101 performs the hoisting operation with a suitable opening and closing degree, which is convenient for the hoisting device to perform the hoisting operation stably;

[0034] After the installation frame 3 slides and adjusts on the hoisting rope 101, the threaded rod 802 is driven to rotate through the driving pin 803. During the rotation of the threaded rod 802, through the meshing transmission between the threaded rod 802 and the threaded sleeve 801, the transmission plate 602 is driven to move. During the movement of the transmission plate 602, through the sliding guiding action of each second sleeve 701 and the second sliding rod 702, the transmission plate 602 moves downward after being stressed. During the downward movement of the transmission plate 602, through the interaction between the two groups of inclined slots 603 and the two groups of transmission pins 604 respectively, the two limiting plates 402 are driven to move towards the two limiting card slots 401 respectively. During the movement, through the extrusion effect, both sides of the hoisting rope 101 are abutted against the arc-shaped slots 403 on the limiting card slots 401 and the limiting plates 402 respectively, so that the installation frame 3 after sliding adjustment is limited and fixed on the hoisting rope 101, which is further convenient for maintaining the state after the opening and closing degree of the hoisting rope 101 is adjusted.
