[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model provides a technical solution, such as Figure 1-Figure 4 As shown; a detachable lifting device acting on a steel beam, comprising: an upper pressure seat 1, which is placed on the upper surface of the steel beam, and an adjusting shaft 11 is arranged above the upper pressure seat, the adjusting shaft 11 and the upper pressure seat 1 are slidably connected through a shaft seat 12, and limit baffles 111 are arranged on both sides of the center of the adjusting shaft 11, and the two limit baffles 111 are respectively located on the outside of the shaft seat 12, linkage keys 112 are arranged at both ends of the outer surface of the adjusting shaft 11, a lifting rod 13 is installed at the center of the adjusting shaft 11, and a lifting ring 14 is installed on the lifting rod 13.

[0033] In the embodiment of the utility model, by utilizing the setting of the lifting rod 13 and through the lifting ring 14, it can be quickly connected with the external lifting equipment and lifted, which is convenient for operation. Secondly, by utilizing the pulling force of the lifting rod 13 during lifting, the lifting rod 13 can drive the adjusting shaft 11 to rotate, and then the rotating adjustment mechanism 3 drives the lower support plate 2 to move upward, so that the steel beam is fixed by the squeezing of the upper pressure seat 1 and the lower support plate 2, effectively avoiding the problem of the steel beam falling during lifting.

[0034] In the embodiment of the utility model, the setting of the rotating seat 12 and the limit baffle 111 can ensure that the position of the adjusting shaft 11 remains fixed while it rotates freely, thereby avoiding the device from shifting and ensuring the stability of the steel beam during hoisting.

[0035] In the embodiment of the utility model, by utilizing the setting of the upper pressure seat 1, on the one hand, the steel beam can be squeezed through the contact between the upper pressure seat 1 and the upper surface of the steel beam, so that the steel beam can be fixed by squeezing to ensure the stability of its hoisting; on the other hand, the upper pressure seat 1 can be utilized to strengthen the structure of the steel beam to avoid the problem of deformation caused by excessive force on the hoisting part of the steel beam during hoisting, thereby ensuring the shape and structural strength of the steel beam itself.

[0036] The lower support plate 2 is arranged below both sides of the upper end surface of the steel beam, and a grid-type reinforcing bracket 21 is arranged on the lower surface thereof.

[0037] In the embodiment of the utility model, the support of the lower support plate 2 below the two ends of the upper end surface of the steel beam can make it possible to lift the steel beam by hoisting, and the setting of the upper pressure seat 1 can fix the steel beam by squeezing, which effectively facilitates the hoisting of the steel beam. The setting of the grid-type reinforcing bracket 21 can improve the strength of the lower support plate 2, avoid bending, breaking, etc. during the hoisting process, and ensure the safety of the hoisting.

[0038] The rotation adjustment mechanism 3 is arranged on both sides of the steel beam, and includes: an adjustment frame 31, which is located on both sides of the steel beam, and its lower end is fixedly connected to the grid-type reinforcing bracket 21, and observation grooves 311 are opened on the side surfaces of both sides; an adjustment bolt 32, which is threadedly installed at the center of the upper surface of the adjustment frame 31, and the lower end is inserted into the adjustment frame 31, and an adjustment pressure plate 321 is arranged below it, and the adjustment pressure plate 321 is located in the adjustment frame 31 and is movably connected with the adjustment bolt 32; an adjustment sleeve 33, which is sleeved on both ends of the adjustment shaft 11, and is inserted in the observation groove 311, and is located below the adjustment pressure plate 321, and a linkage key groove 331 is opened on it, and the linkage key groove 331 is sleeved on the linkage key 112, and a fastening bolt 332 is threadedly installed at one end of its outer surface, and the fastening bolt 332 is in contact with the adjustment shaft 11, and a circular adjustment seat 333 is installed at the center of its outer surface, and the circular adjustment seat 333 is located inside the adjustment frame 31 and in sliding contact with the adjustment pressure plate 321.

[0039] In the embodiment of the utility model, by utilizing the setting of the adjusting sleeve 33 and through the cooperation of the linkage key 112 and the linkage key slot 331, the adjusting sleeve 33 can be able to rotate synchronously with the adjusting shaft 11, and the adjusting sleeve 33 can be slidably adjusted on the adjusting shaft 11, thereby facilitating the control of the position of the adjusting frame 31. On the one hand, it can facilitate the disassembly and assembly of the device on the steel beam, and on the other hand, it can increase the lifting range of the device to meet the lifting needs of steel beams of different sizes.

[0040] In the embodiment of the utility model, the circular adjustment seat 333 is used to perform rotation adjustment along with the rotation of the adjustment shaft 11, so that the contact position with the adjustment pressure plate 321 is controlled by rotation, and then the height of the adjustment pressure plate 321 is controlled, so that the device can quickly fix and release the steel beam, which is convenient for the operation and use of the staff. In addition, during the hoisting process, the dragging force of the wire rope can be used to ensure the stability of the connection between the steel beam and the device, thereby avoiding safety accidents during the hoisting of the steel beam.

[0041] In the embodiment of the utility model, the adjustment frame 31 is set up and connected with the grid-type reinforcing bracket 21 so that the position can be adjusted along with the adjustment sleeve 33. At the same time, the position of the adjustment pressure plate 321 can be adjusted to control the clamping thickness of the device. On the one hand, the firmness of the connection between the steel beam and the device can be ensured. On the other hand, the device can meet the needs of hoisting steel beams of different sizes.

[0042] In the utility model, both ends of the adjustment shaft 11 extend out of the adjustment frame 31 through the observation slot 311 respectively; the adjustment frame 31 can be adjusted within a certain range on the adjustment shaft 11 to facilitate the rapid disassembly and assembly of the device and the steel beam.

[0043] In the present invention, the width of the observation slot 311 is smaller than the diameter of the circular adjustment seat 333 , which can prevent the circular adjustment seat 333 from moving out of the adjustment frame 31 , thereby ensuring the stability of the internal structure of the adjustment frame 31 when the position is adjusted.

[0044] In the utility model, one end of the circular adjustment seat 333 is a plane, and the angle between the plane and the lifting rod 13 is 90°; by using the plane on the circular adjustment seat 333, the upward height of the lower support plate 2 can be adjusted through the contact between the plane and the arc surface with the adjusting pressure plate 321 respectively, so that when the arc surface contacts the adjusting pressure plate 321, the steel beam can be fixed by the extrusion of the lower support plate 2 and the upper pressure seat 1, and when the plane contacts the adjusting pressure plate 321, the lower support plate 3 is spaced a certain distance from the lower surface of the upper end face of the steel beam, which is convenient for moving and disassembling the device on the steel beam.

[0045] In the utility model, when the hoisting rod 13 is facing one end of the steel beam, the plane on the circular adjustment seat 333 faces directly upward and contacts the adjustment pressure plate 321; when the steel beam is hoisted, the hoisting rod 13 is rotated toward the top of the center of the steel beam, and the gravity of the steel beam is used to ensure the stability of the position of the hoisting rod 13, thereby ensuring safety during hoisting.

[0046] In the utility model, when the position of the lower support plate 2 is adjusted, the two ends of the upper pressure seat 1 are always located above the lower support plate 2, thereby avoiding the lower support plate 2 and the upper pressure seat 1 being completely misaligned, causing the upper end surface of the steel beam to receive shear force, thereby ensuring the structural strength of the steel beam itself.

[0047] When the utility model is used specifically, the staff takes out two devices. When installing, the devices can be inserted into the steel beam from both ends of the steel beam respectively, so that the upper pressure seat 1 is placed on the upper end surface of the steel beam, and the lower support plate 2 is placed on both sides below the upper end surface of the steel beam. Then, the pushing device is slid on the steel beam to move it to a suitable position of the steel beam.

[0048] Afterwards, the staff can loosen the fastening bolts 332 so that the rotating adjustment mechanism 3 can slide and adjust on the adjusting shaft 11, and make the adjusting frame 31 and the steel beam separated by a suitable distance, and then tighten the fastening bolts 332. After the adjustment is completed, the staff rotates the lifting rod 13 to drive the adjusting shaft 11 to rotate, and through the cooperation of the linkage key 112 and the linkage key slot 331, the adjusting sleeve 33 drives the circular adjusting seat 333 to rotate. The staff rotates the adjusting bolts 32 with the tool to drive the adjusting pressure plate 321 to adjust the height, and adjusts the position of the lower support plate 2 to a suitable position, so that the upper pressure seat 1 and the lower support plate 2 can utilize the rotation of the circular adjustment seat 333 to clamp the steel beam.

[0049] When the device is adjusted separately, the staff then rotates the lifting rod 13, and uses the lifting rod 13 to drive the adjustment shaft 11 to rotate, so that it drives the adjustment sleeve 33 to rotate, and then the plane of the circular adjustment seat 333 gradually moves away from under the adjustment pressure plate 321, and the arc surface gradually contacts the adjustment pressure plate 321, and then uses its arc surface to support the adjustment pressure plate 321, so that it drives the adjustment frame 31 to move upward, and then drives the lower support plate 2 to move upward, so that the upper pressure seat 1 and the lower support plate 2 clamp the steel beam, and then the lifting ring 13 can be connected to the external lifting equipment to lift the steel beam to a suitable position.

[0050] During the steel beam hoisting process, the hoisting position is generally located above the center of the steel beam, and is connected to the lifting ring 14 through a wire rope and a hook, so that the hoisting equipment lifts the steel beam through the hoisting wire rope. In this process, due to the pulling of the wire rope, the hoisting rod 13 rotates toward the center of the steel beam, and then the rotation angle of the hoisting rod 13 is greater than 90°. At this time, the contact position between the circular adjustment seat 333 and the adjustment pressure plate 321 is still an arc surface, which can ensure the stability of the steel beam during hoisting and prevent it from falling.

[0051] When the device is implemented, in order to ensure the clamping force of the upper pressure seat 1 and the lower support plate 2 on the steel beam, the staff can adjust the adjusting plate 321 to a suitable height, and then make the plane of the circular adjusting seat 333 contact the adjusting plate 321 again, and use the tool to control the rotation of the adjusting bolt 32 again, so that the height of the adjusting plate 321 is slightly lowered, and then the arc surface of the circular adjusting seat 333 is in contact with the adjusting plate 321. Then, the distance between the lower support plate 2 and the upper pressure seat 1 is smaller, and the steel beam can be clamped more tightly. When the lifting rod 13 rotates, its rotation resistance is too large, and the staff can use an external crowbar to assist its rotation adjustment.
