Specific embodiment
As shown in Figure 1, movable mechanical self-locking crane of the invention includes: trolley 1, pull rod 2, frame 11, lifting
Nose 8, Manual press device 10, the first self-locking brace 5, the second self-locking brace 12, attachment device 7, the first spring 6 and second spring
9,2 lower end of pull rod is vertically fixed on trolley 1, and hand-push apparatus 4 and at least three wheels 13 are housed on trolley 1.On pull rod 2
It is set with frame 11, the rectangle that frame 11 is made of three sides.Frame 11 is moved up and down along pull rod 11, the one of frame 11
It is fixed with lifting nose 8 on side, lifts by crane and is provided with hole on nose 8, for hanging weight.Manual press is provided in the other side of frame 11
One end of device 10, Manual press device 10 is hinged by shaft 3 and frame 11, and the middle part of Manual press device 10 and second is certainly
Lock brace 12 one end it is hinged, the other end of the second self-locking brace 12 is sleeved on pull rod 2, and with pull rod 2 formed upwards it is self-locking,
It is also equipped with second spring 9 between the second self-locking brace 12 and frame 11, first self-locking brace 5 is housed in the top of frame 11,
The middle part of first self-locking brace 5 is sleeved on pull rod 12, and is formed with pull rod 2 self-locking upwards, and one end of the first self-locking brace 5 is logical
It crosses the first spring 6 to be connected with frame 11, the other end of the first self-locking brace 5 is connected by attachment device 7 with frame 11.First certainly
There is slideway on lock brace 5, the second self-locking brace 12 and the pull rod 2 that matches with the first self-locking brace 5, the second self-locking brace 12
14, when so that frame 11 being moved upwards along pull rod 12, the first self-locking brace 5 and the second self-locking brace 12 respectively with 2 shape of pull rod
