[0002] During the construction process, it is usually necessary to hoist the steel beam to a high altitude construction location. After the steel beam is hoisted into place, the construction workers are required to release the connection between the hoist and the steel beam. However, the construction location is generally high, and manual release of the connection requires high-altitude work, which poses a greater safety risk. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide an automatic unhooking hoist for steel beams and a method of using the same, which solves the problem of high safety risks of manual unhooking. After the steel beam is hoisted into place, the hoist automatically unhooks to avoid manual unhooking, reduce safety risks, and ensure the safety of construction workers. The invention also has a simple structure and is easy to implement.

[0004] The technical solution to achieve the above purpose is:

[0005] The present invention provides an automatic unhooking hanger for a steel beam, comprising:

[0006] A stress-bearing rod vertically mounted on the steel beam, the bottom of the stress-bearing rod being bent upward to form a hook portion;

[0007] A baffle having one end rotatably connected to the end of the hook portion and the other end abutting against the force bearing rod; and

[0008] The shackle is buckled on the hook part and fixedly connected to the lifting equipment. The steel beam is lifted by the lifting equipment to drive the shackle to move upward along the load-bearing rod and push the baffle to rotate, so that the shackle is disengaged from the hook part and is sleeved on the load-bearing rod. Then the shackle is lowered by the lifting equipment, so that the shackle moves downward along the load-bearing rod and the baffle, thereby detaching from the load-bearing rod.

[0009] The automatic unhooking hoist of the steel beam of the present invention has a shackle clamped in the area enclosed by the baffle and the hook portion. When the lifting equipment lifts the steel beam, the shackle is driven to move upward along the load-bearing rod and push the baffle to rotate, so that the shackle is disengaged from the hook portion and sleeved on the load-bearing rod. The lifting equipment is then used to lower the shackle, so that the shackle moves downward along the load-bearing rod and the baffle, thereby disengaging from the load-bearing rod. That is, the shackle can be automatically disengaged from the load-bearing rod and the hook portion, reducing the time for construction personnel to work at high altitudes and solving the problem of high safety risks of manual unhooking. After the steel beam is hoisted into place, the hoist is automatically unhooked, avoiding manual unhooking, reducing safety risks, and ensuring the safety of construction personnel. The structure is simple and easy to implement.

[0010] A further improvement of the automatic unhooking hanger for steel beams of the present invention is that the elevation position of the end of the baffle against the force-bearing rod is higher than the elevation position of the end of the baffle rotatably connected to the hook portion, so that the baffle is tilted downward.

[0011] A further improvement of the automatic unhooking hanger for steel beams of the present invention is that the cross section of the steel beam is I-shaped, including two wing plates arranged opposite to each other and a web plate connected between the two wing plates;

[0012] The stress-bearing rod is opposite to the web plate and is installed on one wing plate, and a set distance is provided between the bottom of the stress-bearing rod and the other wing plate.

[0013] A further improvement of the automatic unhooking hanger for steel beams of the present invention is that it also includes a clamping piece installed on the wing plate, and the positioning rod is fixed to the bottom of the clamping piece.

[0014] A further improvement of the automatic unhooking hanger for steel beams of the present invention is that the clamping member comprises an L-shaped plate with an L-shaped vertical section, a screw rod fixed to the top of the L-shaped plate, a clamping plate sleeved on the screw rod, and a nut screwed on the screw rod, a through hole is opened in the wing plate corresponding to the screw rod, and the force-bearing rod is fixed to the bottom of the L-shaped plate;

[0015] The screw rod passes through the wing plate through the through hole, and the clamping plate is sleeved on the screw rod, and then the nut is screwed on the screw rod, so that the clamping plate and the L-shaped plate are clamped on the wing plate, and the load-bearing rod is fixed to the steel beam.

[0016] A further improvement of the automatic unhooking hanger for steel beams of the present invention is that two screw rods are arranged opposite to each other.

[0017] A further improvement of the automatic unhooking lifting device for steel beams of the present invention is that the shackle includes a U-shaped portion and a closing rod connected to the open end of the U-shaped portion to close the opening of the U-shaped portion, and the closing rod is passed through the area enclosed by the bent hook portion and the baffle. When the lifting equipment lifts the steel beam upward, the closing rod pushes the baffle to rotate, so that the shackle is separated from the bent hook portion, and the U-shaped portion and the closing rod are against the bottom of the clamp.

[0018] A further improvement of the automatic unhooking hanger for steel beams of the present invention is that the blocking piece is rotatably connected to the end of the hook portion via a rotating shaft.

[0019] The present invention provides a method for using an automatic unhooking hanger for a steel beam, comprising the following steps:

[0020] Provide an automatic unhooking sling to fix the load-bearing rod to the steel beam, and a shackle is provided on the hook portion to fix the hook portion to the lifting equipment;

[0021] Start the lifting equipment to drive the shackle to move upward along the stress rod and push the blocking plate to rotate, so that the shackle is released from the hook portion and sleeved on the stress rod;

[0022] After the steel beam is transported to its place, the shackle is lowered by the lifting equipment, so that the shackle moves downward along the load-bearing rod and the baffle, and then comes out from the bottom of the load-bearing rod.

[0023] A further improvement of the method for using the automatic unhooking hanger for steel beams of the present invention is that the elevation position of the end of the baffle plate against the force-bearing rod is higher than the elevation position of the end of the baffle plate rotatably connected to the hook portion, so that the baffle plate is tilted downward;

[0024] The shackle is lowered by a lifting device so that the shackle moves downward along the baffle to prevent the shackle from being stuck in the hook portion. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1 The present invention provides an automatic unhooking sling for steel beams and a method for using the same. The shackle is clamped in the area enclosed by the baffle and the hook portion. When the lifting equipment lifts the steel beam, the shackle is driven to move upward along the force-bearing rod and push the baffle to rotate, so that the shackle is disengaged from the hook portion and sleeved on the force-bearing rod. The lifting equipment is then used to lower the shackle, so that the shackle moves downward along the force-bearing rod and the baffle, thereby disengaging from the force-bearing rod. That is, the shackle can automatically disengage from the force-bearing rod and the hook portion, reducing the time for construction personnel to work at high altitudes, solving the problem of high safety risks of manual unhooking. After the steel beam is hoisted into place, the sling automatically unhooks, avoiding manual unhooking, reducing safety risks, and ensuring the safety of construction personnel. The structure is simple and easy to implement. The automatic unhooking sling for steel beams of the present invention is described below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 3 As shown, the automatic unhooking hanger for steel beams of the present invention comprises:

[0032] A stress-bearing rod 11 vertically mounted on the steel beam 21, wherein the bottom of the stress-bearing rod 11 is bent upward to form a hook portion 111;

[0033] One end is rotatably connected to the end of the hook portion 111 and the other end is against the blocking piece 12 of the force bearing rod 11; and

[0034] The shackle 13, which is buckled on the hook portion 111 and fixedly connected to the lifting equipment, lifts the steel beam 21 by the lifting equipment to drive the shackle 13 to move upward along the load-bearing rod 11 and push the baffle 12 to rotate, so that the shackle 13 is disengaged from the hook portion 111 and is sleeved on the load-bearing rod 11, and then the shackle 13 is lowered by the lifting equipment, so that the shackle 13 moves downward along the load-bearing rod 11 and the baffle 12, thereby detaching from the load-bearing rod 11.

[0035] Preferably, the blocking piece 12 is rotatably connected to the end of the hook portion 111 via a rotating shaft.

[0036] As a preferred embodiment of the present invention, the elevation position of the end of the baffle 12 against the load-bearing rod 11 is higher than the elevation position of the end of the baffle 12 rotatably connected to the hook portion 111, so that the baffle 12 is tilted downward, that is, when the shackle 13 is lowered, the shackle 13 can be separated from the load-bearing rod 11 along the inclined baffle 12, thereby preventing the shackle 13 from being re-stuck in the hook portion 111.

[0037] Furthermore, the cross section of the steel beam 21 is I-shaped, including two wing plates 211 arranged opposite to each other and a web plate 212 connected between the two wing plates 211;

[0038] The stress-bearing rod 11 is opposite to the web 212 and is mounted on one wing plate 211 , and there is a set distance between the bottom of the stress-bearing rod 11 and the other wing plate 211 .

[0039] Furthermore, it also includes a clamping member 14 installed on the wing plate 211 , and the positioning rod 11 is fixed to the bottom of the clamping member 14 .

[0040] Specifically, the clamp 14 includes an L-shaped plate 141 with an L-shaped vertical section, a screw 143 fixed to the top of the L-shaped plate 141, a clamping plate 142 for sleeved on the screw 143, and a nut 1431 screwed on the screw 143. The wing plate 211 is provided with a through hole corresponding to the screw 143, and the force-bearing rod 11 is fixed to the bottom of the L-shaped plate 141.

[0041] The screw 143 passes through the wing plate 211 through the through hole, and the clamping plate 142 is sleeved on the screw 143, and then the nut 14311 is screwed on the screw 143, so that the clamping plate 142 and the L-shaped plate 141 are clamped on the wing plate 211, so that the load-bearing rod 11 is fixed to the steel beam.

[0042] Preferably, two screw rods 143 are arranged opposite to each other.

[0043] Furthermore, the shackle 13 includes a U-shaped portion 131 and a closing rod 132 connected to the open end of the U-shaped portion 131 to close the opening of the U-shaped portion 131. The closing rod 132 is inserted into the area enclosed by the hook portion 111 and the baffle 12. When the lifting equipment lifts the steel beam 21 upward, the closing rod 132 pushes the baffle 12 to rotate, so that the shackle 13 is disengaged from the hook portion 111, and the U-shaped portion 131 and the closing rod 132 are against the bottom of the clamp 14.

[0044] The specific implementation method of the present invention is as follows:

[0045] The L-shaped plate 141 is clamped on the wing plate 211. At this time, the vertical plate of the L-shaped plate 141 is against the side of the wing plate 211, and the horizontal plate of the L-shaped plate 141 is attached to the bottom surface of the wing plate 211. The screw 143 is inserted into the through hole of the wing plate 211, and the clamping plate 142 is sleeved on the screw 143, and then the nut 1431 is screwed on the screw 143, so that the clamping plate 142 and the L-shaped plate 141 are clamped on the wing plate 211, and the force-bearing rod 11 is fixed to the wing plate 211;

[0046] The baffle 12 is rotated to insert the closing rod 132 of the shackle 13 into the area enclosed by the hook portion 111 and the baffle 12, and the lifting equipment is fixedly connected to the shackle 13. The lifting equipment is started to lift the steel beam 21 upward. At this time, the shackle 13 moves upward along the force-bearing rod 11 and pushes the baffle 12 upward, so that the baffle 12 rotates, so that the shackle 13 is separated from the hook portion 111 and abuts against the bottom of the L-shaped plate 141;

[0047] After the steel beam 21 is hoisted into place, the shackle 13 is lowered by a lifting device. Under the action of its own gravity, the shackle 13 moves downward along the load-bearing rod 11 to the baffle 12. Since the baffle 12 is tilted downward, the shackle 13 can continue to slide down along the baffle 12 until it is separated from the load-bearing rod 11, thereby completing the unhooking. The downwardly tilted baffle 12 can also prevent the shackle 13 from being re-stuck in the hook portion 111.

[0048] The present invention also provides a method for using the automatic unhooking hanger for steel beams, the method comprising the following steps:

[0049] An automatic unhooking sling is provided, the force bearing rod 11 is fixed to the steel beam 21, and the shackle 13 is buckled on the hook portion 111, and the hook portion 111 is fixedly connected to the lifting equipment;

[0050] Start the lifting equipment to drive the shackle 13 to move upward along the stress rod 11 and push the blocking plate 12 to rotate, so that the shackle 13 escapes from the hook portion 111 and is sleeved on the stress rod 11;

[0051] After the steel beam 21 is transported to the position, the shackle 13 is lowered by a lifting device, so that the shackle 13 moves downward along the load-bearing rod 11 and the baffle 12 , and then comes out from the bottom of the load-bearing rod 11 .

[0052] Furthermore, the elevation position of the end of the baffle 12 abutting against the force-bearing rod 11 is higher than the elevation position of the end of the baffle 12 rotatably connected to the hook portion 111, so that the baffle 12 is tilted downward;

[0053] The shackle 13 is lowered by using a lifting device, so that the shackle 13 moves downward along the blocking piece 12 , thereby preventing the shackle 13 from being stuck in the hook portion 111 .

[0054] The actual operation mode of the method provided by the present invention is as follows:

[0055] The L-shaped plate 141 is clamped on the wing plate 211. At this time, the vertical plate of the L-shaped plate 141 is against the side of the wing plate 211, and the horizontal plate of the L-shaped plate 141 is attached to the bottom surface of the wing plate 211. The screw 143 is inserted into the through hole of the wing plate 211, and the clamping plate 142 is sleeved on the screw 143, and then the nut 1431 is screwed on the screw 143, so that the clamping plate 142 and the L-shaped plate 141 are clamped on the wing plate 211, and the force-bearing rod 11 is fixed to the wing plate 211;

[0056] The baffle 12 is rotated to insert the closing rod 132 of the shackle 13 into the area enclosed by the hook portion 111 and the baffle 12, and the lifting equipment is fixedly connected to the shackle 13. The lifting equipment is started to lift the steel beam 21 upward. At this time, the shackle 13 moves upward along the force-bearing rod 11 and pushes the baffle 12 upward, so that the baffle 12 rotates, so that the shackle 13 is separated from the hook portion 111 and abuts against the bottom of the L-shaped plate 141;

[0057] After the steel beam 21 is hoisted into place, the shackle 13 is lowered by a lifting device. Under the action of its own gravity, the shackle 13 moves downward along the load-bearing rod 11 to the baffle 12. Since the baffle 12 is tilted downward, the shackle 13 can continue to slide down along the baffle 12 until it is separated from the load-bearing rod 11, thereby completing the unhooking. The downwardly tilted baffle 12 can also prevent the shackle 13 from being re-stuck in the hook portion 111.

[0058] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
