Embodiment 1
[0031] Such as image 3 As shown, a special spreader for steel structures that is easy to disassemble includes a spreader body 1, a fixed structure 2, a locking structure 3 and a pull rope 4. The spreader body 1 includes a connecting block 1.1, a first sleeve 1.2 and a second The casing 1.3, the first casing 1.2 is perpendicular to the axis of the second casing 1.3, the connecting block 1.1 is provided with a socket 1.1.3, the socket 1.1.3 passes through the connecting groove 1.1.2 transversely, the first casing 1.2 The side wall of the side wall is provided with a first slide groove 1.2.1 and a first lock groove 1.2.2 which communicate with each other.
[0032] The fixed structure 2 includes a fixed pin 2.1, a first pull rod 2.2 and a first telescopic spring 2.3. The fixed pin 2.1 is arranged in the first sleeve 1.2 and is slidably connected with the first sleeve 1.2. The fixed pin 2.1 can move along the first sleeve 1.2. One end of the fixed bolt 2.1 passes through the sock...
Embodiment 2
[0036] Such as figure 1 As shown, a special spreader for steel structures that is easy to disassemble includes a spreader body 1, a fixed structure 2, a locking structure 3 and a pull rope 4. The spreader body 1 includes a connecting block 1.1, a first sleeve 1.2 and a second Sleeve 1.3, connecting block 1.1 is provided with jack 1.1.3, connecting hole 1.1.1 and connecting groove 1.1.2, jack 1.1.3 passes through connecting groove 1.1.2 transversely, side wall of first bushing 1.2 There are interconnected first chute 1.2.1 and first lock groove 1.2.2; the side wall of the second casing 1.3 is provided with interconnected second chute 1.3.1 and second lock groove 1.3. 2.
[0037] The fixed structure 2 includes a fixed pin 2.1, a first pull rod 2.2 and a first telescopic spring 2.3. The fixed pin 2.1 is arranged in the first sleeve 1.2 and is slidably connected with the first sleeve 1.2. The fixed pin 2.1 can move along the first sleeve 1.2. One end of the fixed bolt 2.1 passes...
Embodiment 3
[0041] Such as figure 1 and figure 2 As shown, on the basis of Example 2, the first pull rod 2.2 and the second pull rod 3.2 are connected to the same pull rope 4; the second pull rod 3.2 is provided with an elastic stretchable part 5, and one end of the elastic stretchable part 5 is connected to the second The pull rod 3.2 is connected, and one end of the stay rope 4 is fixed to the elastic stretchable member 5 and passed through the elastic stretchable member 5 and connected with the first pull rod 2.2.
[0042] In the above technical solution, the elastic stretchable member 5 may be a stretchable spring or an elastic elastic rope or other elastic members. One end of the stay rope 4 is bound on the first pull rod 2.2, and after leaving an appropriate margin, tie a knot and then tie it on the elastic expansion member 5 on the second pull rod 3.2. The effect of the elastic telescopic member 5 is to adjust the length of the rope between the two pull rods, and give the second...
