Among the figure: 1, frame, 2, main shaft, 3, support arm, 4, claw, 5, ratchet, 6, cylinder, 7, tooth bar, 8, sensor, 9, induction rod, 10, connecting rod, 11, slide bar, 12, slider block, 13, spring, 14, limited block, 15, cylinder, 16, piston rod, 17, location fork, 18, guide wheel, 19, column.
The specific embodiment
Shown in Fig. 1,2,3 and 4, a kind of chassis, comprise frame 1, be arranged on the main shaft 2 on the frame 1, be fixedly installed on some support arms 3 at main shaft 2 tops, be arranged on the claw 4 on the support arm 3, main shaft 2 is provided with ratchet 5, and ratchet 5 rotates by unilateral bearing and is arranged on the main shaft 2, and ratchet 5 is meshed with tooth bar 7, tooth bar 7 directly is connected with the piston rod of cylinder 6, and cylinder 6 is fixedly installed on the frame 1; Described tooth bar 7 outsides also are provided with a guide wheel 18, and guide wheel 18 offsets with the outside of tooth bar 7, and guide wheel 18 is fixed on the frame 1 by column 19; Between frame 1 and main shaft 2, be provided with stopping means, also be provided with positioner between frame 1 and the support arm 3.In the present embodiment, cylinder 6 also can change the transmission device of other form into, and as oil cylinder etc., but its cost is than cylinder height.
Stopping means in the foregoing description comprises an end and tooth bar 7 outsides connecting rod 10 that connects of hinge mutually, the middle part hinge of connecting rod 10 is met sb. at the airport on the frame 1, one end of the other end of connecting rod 10 and slide bar 11 offsets, slide bar 11 is arranged in the slider block 12 by spring 13, the other end of slide bar 11 and the some limited blocks 14 mutual corresponding matching that are arranged on the main shaft 2, limited block 14 is arranged on the main shaft 2 of support arm 3 downsides, and limited block 14 is corresponding with support arm 3 respectively.
Above-mentioned positioner comprises the sensor 8 that is arranged on the frame 1, be arranged on the support arm 3 and with sensor 8 corresponding induction rods 9, sensor 8 is connected with cylinder 15 by control device, cylinder 15 is arranged on the frame 1, cylinder 15 is connected with location fork 17 by piston rod 16, and location fork 17 is arranged on support arm 3 downsides and corresponding with support arm 3.
During this chassis work, start cylinder 6 work, driving tooth bar 7 by cylinder 6 by piston rod travels forward, what drive was engaged with rotates with ratchet 5, because only can drive main shaft 2 in a direction when this ratchet 5 rotates rotates, dally during answer, can not drive main shaft 2 rotates, ratchet 5 drives main shaft 2 rotations, thereby driving the some support arms 3 and the claw 4 on the support arm 3 that are arranged on the main shaft 2 rotates together, when tooth bar 7 drove ratchet 5 rotations, an end was hinged and connected to the also swing simultaneously of connecting rod 10 on the tooth bar 7, the slide bar 11 that the other end promotion of connecting rod 10 offsets with it, slide bar 11 is stretched out in slider block 12, when main shaft 2 drive support arms 3 turned to certain position, the external part of slide bar 11 was just inconsistent with the limited block 14 that turns over, thereby main shaft 2 is stopped operating.Simultaneously, the induction rod 9 that is arranged on the support arm 3 is corresponding with the sensor 8 on being arranged on frame 1, sensor 8 passes to cylinder 6 and cylinder 15 by control device with induced signal, cylinder 15 moves upward by the location fork 17 that piston rod 16 drives its top, location fork 17 just blocks support arm 3, to prevent that main shaft 2 from driving support arm 3 and rotating with claw 4.Support arm 3 is behind the location of certain hour, and cylinder 6 restarts, and drives tooth bar 7 and does return motion, does not rotate because ratchet 5 can not drive main shaft 2, and this hour rack 7 just resets; Cylinder 15 also restarts, and drives location fork 17 and resets; Simultaneously, tooth bar 7 also drivening rod 10 is also done return motion, because slide bar 11 is arranged in the slider block 12 by spring 13, therefore, slide bar 11 also resets, and prepares the rotation in following cycle together.
