[0018] (2) In this invention, the piston is driven to move away from the sliding block by the movement of the transmission rod. The movement of the piston will inflate the interior of the hollow cylinder through the inflation hole. Since the air cannot flow into the interior of the hollow cylinder through the square hole, the speed of the piston is slowed down when it is reset, preventing the fixed plate from being reset quickly, which may cause the staff to be unable to dodge in time and get injured, further improving the safety of the device when in use.

[0019] (3) The invention prevents the limit block from moving further after being blocked by the triangular block, so that the degree of return of the No. 1 spring is limited, thereby preventing the No. 1 spring from making abnormal noises due to material aging when the No. 1 spring is in a state of accumulation or tension for a long time, thereby affecting the user experience and improving the practicality of the device. The limit block moves so that the triangular block contacts. Since the limit block is not blocked by the one-way baffle, it will not be affected when it moves in the direction of the triangular block, thereby improving the stability of the device when in use.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 - Figure 3 , one embodiment of the present invention is: a spliced ​​steel structure beam, comprising a sling 1, a keel 2 is fixedly installed at the bottom of the sling 1, and a docking device is provided at the bottom of the sling 1;

[0030] The docking device includes: a T-slot 31, a circular slot 32, a nut 33, a fixing block 34, an arc block 35, a vertical plate 36, a sliding block 37, a positioning block 38 and a fixing plate 39, wherein the T-slot 31 is provided on the surface of the keel 2, the circular slot 32 is provided on the top of the keel 2, the nut 33 is fixedly mounted on the bottom of the inner wall of the keel 2, the fixing block 34 is fixedly mounted on the top of the keel 2, the arc block 35 is fixedly mounted on a side of the fixing block 34 close to the T-slot 31, the vertical plate 36 is fixedly mounted on the bottom of the inner wall of the keel 2, and the sliding block 37 is fixedly mounted on the bottom of the inner wall of the keel 2. 7 is slidably mounted on the inner wall of the keel 2, the positioning block 38 is fixedly mounted on the side of the sliding block 37 away from the vertical plate 36, and the fixing plate 39 is fixedly mounted on the side of the positioning block 38 away from the sliding block 37. The keel 2 can be connected by pressing it to the bottom, so that the two keels 2 can be connected quickly, which reduces the difficulty of operation for workers in high-altitude operations and improves the safety of workers in operation. The surface thickness of the keel 2 is reduced by the circular groove 32, which makes it more convenient for workers to drive the drop into the interior of the keel 2, reduces the difficulty of operation and improves work efficiency.

[0031] A No. 1 spring 310 is arranged between the vertical plate 36 and the sliding block 37 . The positioning block 38 contacts the T-shaped slot 31 , and the No. 1 spring 310 drives the sliding block 37 to reset.

[0032] The arc block 35 contacts the positioning block 38 , and the circular hole on the surface of the fixing plate 39 coincides with the circular groove 32 , so that the position of the circular groove 32 is positioned through the circular hole.

[0033] When this embodiment is working: the keel 2 to be spliced ​​is placed on the right side of another keel 2, the positioning block 38 is aligned with the T-slot 31, and then the keel 2 is pressed toward the bottom. The movement of the keel 2 drives the sliding block 37 to move toward the bottom, and the movement of the sliding block 37 drives the positioning block 38 to move toward the bottom. The movement of the positioning block 38 will contact the arc block 35. The positioning block 38 is blocked by the arc block 35, so that the positioning block 38 moves in the direction away from the fixed block 34. The movement of the positioning block 38 drives the sliding block 37 to move in the direction away from the T-slot 31. As the positioning block 38 moves toward the bottom, when the positioning block 38 no longer contacts the arc block 35, the No. 1 spring 310 is reset to drive the sliding block 37 to move in the direction away from the vertical plate 36. The movement of the sliding block 37 drives the fixed block 34. The positioning block 38 moves in the direction away from the vertical plate 36. After the positioning block 38 moves, it is limited by the T-slot 31, so that the positioning block 38 cannot move into the inside of the T-slot 31. The docking can be completed by pressing the keel 2 toward the bottom, so that the two keels 2 can be quickly docked, which reduces the difficulty of operation for workers during high-altitude operations and improves the safety of workers during operations. After the docking is completed, the positioning screw is aligned with the circular hole on the surface of the fixing plate 39, and then the positioning screw is rotated toward the bottom. After the screw is rotated, the circular groove 32 is penetrated, and then the screw is engaged with the thread inside the nut 33 and is limited by the nut 33. The surface thickness of the keel 2 is reduced by the circular groove 32, which makes it more convenient for workers to drive the screw into the inside of the keel 2, reduces the difficulty during operation, and improves work efficiency.

[0034] See also Figure 1 - Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a protective device for protecting the docking and a positioning device for limiting the docking device are arranged inside the keel 2, wherein the protective device comprises: a hollow cylinder 41, a transmission rod 42, a piston 43, an elastic telescopic rod 44, a circular plate 45, a square hole 46, an inflation hole 47 and a sealing block 48, the hollow cylinder 41 is fixedly installed at the inner bottom of the keel 2, the hollow cylinder 41 slides through the inner and outer walls of the sliding block 37, the piston 43 is slidably installed on the inner wall of the hollow cylinder 41, one end of the transmission rod 42 is fixedly installed on the surface of the piston 43, and the other end of the transmission rod 42 is fixedly installed on the surface of the piston 43. One end is fixedly mounted on a side of the positioning block 38 close to the hollow cylinder 41, the elastic telescopic rod 44 is fixedly mounted on a side of the piston 43 away from the transmission rod 42, the circular plate 45 is fixedly mounted on an end of the hollow cylinder 41 away from the piston 43, the square hole 46 is opened on the circumferential surface of the hollow cylinder 41, the inflation hole 47 is opened on the surface of the circular plate 45, and a storage groove is opened at the free end of the elastic telescopic rod 44. The sealing block 48 is slidably mounted on the inner wall of the storage groove, so that the speed of the piston 43 is slowed down when it is reset, preventing the fixed plate 39 from being quickly reset, which may cause the staff to be unable to avoid in time and cause injuries, thereby further improving the safety of the device when in use.

[0035] A No. 2 spring is provided between the sealing block 48 and the receiving groove. The sealing block 48 contacts the square hole 46, and the No. 2 spring drives the sealing block 48 to reset.

[0036] The positioning device includes: a hollow box 51, an L-shaped rod 52, a sliding long rod 53, a rotating rod 54, a sliding cross rod 55, a triangular block 56 and a rotating shaft 510. The hollow box 51 is fixedly installed on the bottom of the inner wall of the keel 2, the L-shaped rod 52 is fixedly installed on the top of the inner wall of the hollow box 51, the sliding long rod 53 is slidably installed on the bottom of the inner wall of the hollow box 51, the rotating shaft 510 is rotatably installed on the inner wall of the hollow box 51, the rotating rod 54 is fixedly installed on the surface of the rotating shaft 510, the sliding cross rod 55 is slidably installed on the inner wall of the hollow box 51, one end of the rotating rod 54 is rotatably installed on the surface of the sliding long rod 53, the rotating rod 54 is rotatably installed on the surface of the sliding cross rod 55, and the triangular block 56 is fixedly installed on the top of the sliding cross rod 55.

[0037] The positioning device also includes: a limit plate 57, a limit block 58 and a one-way baffle 59. The limit plate 57 is fixedly installed on a side of the sliding block 37 close to the vertical plate 36, the limit block 58 is rotatably installed on the end of the limit plate 57 away from the sliding block 37, and the one-way baffle 59 is fixedly installed on the top of the limit plate 57, so that the degree of resetting of the No. 1 spring 310 is limited, preventing the No. 1 spring 310 from making abnormal noises due to material aging when the No. 1 spring 310 is in a power storage or tension state for a long time, thereby affecting the use experience, improving the practicality of the device, and ensuring that the limit block 58 will not be affected when it moves in the direction of the triangular block 56, thereby improving the stability of the device during use.

[0038] A torsion spring is provided between the limit block 58 and the limit plate 57 . The limit block 58 contacts the triangular block 56 , and the limit block 58 is driven by the torsion spring to reset.

[0039] When the present embodiment is working, when the positioning block 38 moves toward the direction of the vertical plate 36, the positioning block 38 moves to drive the transmission rod 42 to move toward the direction of the sliding block 37, and the transmission rod 42 moves to drive the piston 43 to move toward the direction of the sliding block 37. The movement of the piston 43 squeezes the air inside the hollow cylinder 41 to be discharged from the square hole 46 and the inflation hole 47. The movement of the piston 43 drives the elastic telescopic rod 44 to move toward the direction of the circular plate 45. The movement of the elastic telescopic rod 44 drives the sealing block 48 to move toward the direction of the square hole 46. When the sealing block 48 moves and contacts the square hole 46, the sealing block 48 is driven to move away from the elastic telescopic rod 44 through the second spring reset. After the sealing block 48 moves, the inner square hole 46 is limited, so that the sealing Block 48 is inserted into the interior of square hole 46 and seals square hole 46, so that air cannot flow through square hole 46. When positioning block 38 moves in the direction away from sliding block 37, positioning block 38 moves to drive transmission rod 42 to move in the direction away from sliding block 37. Transmission rod 42 moves to drive piston 43 to move in the direction away from sliding block 37. The movement of piston 43 will inflate the interior of hollow cylinder 41 through inflation hole 47. Since air cannot flow into the interior of hollow cylinder 41 through square hole 46, the speed of piston 43 when resetting is slowed down, preventing the fixing plate 39 from being quickly reset, which may cause the staff to be unable to dodge in time and get injured, thereby further improving the safety of the device when in use.

[0040] The movement of the sealing block 48 will contact the sliding cross bar 55, and the movement of the sealing block 48 will drive the sliding cross bar 55 to move to the top. The movement of the sliding cross bar 55 will drive the rotating rod 54 to rotate. After the rotating rod 54 rotates, it will be stuck in the inside of the hollow box 51 and support the sliding cross bar 55. The movement of the sliding block 37 drives the limit plate 57 to move away from the triangular block 56. The movement of the limit plate 57 will drive the limit card block 58 to move. The limit card block 58 moves and contacts the triangular block 56, so that the limit card block 58 cannot continue to move after being blocked by the triangular block 56, so that the first spring 310 The degree of resetting is limited to prevent the No. 1 spring 310 from making abnormal noises due to material aging when the No. 1 spring 310 is in a state of storing force or stretching for a long time, thereby affecting the use experience and improving the practicality of the device. The movement of the sliding block 37 drives the limit plate 57 to move in the direction of the triangular block 56. The movement of the limit plate 57 will drive the limit block 58 to move. The movement of the limit block 58 will contact the triangular block 56. Since the limit block 58 is not blocked by the one-way baffle 59, it will not be affected when the limit block 58 moves in the direction of the triangular block 56, thereby improving the stability of the device during use.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
