The adjusting screw rod connection of lever apparatus, and can be slided in piston shoes；Roller in roller erecting device is installed on slide bar by wheel shaft
It is in the following, with the slip of slide bar and flexible.
The piston shoes are made of four pieces of piston shoes risers, wherein, front and rear two pieces of piston shoes risers top is provided with pin hole-and positioning
Screw hole, two pieces of left and right piston shoes riser lower part are welded with bottom blend stop；Eight positive stop strips are arranged at the edge of four pieces of risers of the slide bar,
Positive stop strip and bottom blend stop are formed with guiding, the mechanism of limit function.
The push rod device is made of adjusting screw rod, locating clamp plate, pinboard, clevis bolt and adjusting nut, adjusts spiral shell
For master card in the U-type groove of the locating clamp plate on both sides, the pin hole of pinboard through piston shoes compresses adjusting nut；And can be by tearing open
Dismounting to whole device can simply and easily be realized by plugging pin plate.
Using the above scheme, the present invention has the advantage that and has the beneficial effect that：
Wheel is stretched out outside piston shoes, and movement is rolled by realizing after steel, convenient walking, after annular steel by segment in installment work, again
It can be adjusted by push rod device, and in pushing tow working status, unnecessary wheels retracted, there is provided stable working environment.Separately
Outside, whole expanding pulley apparatus structure design is easy to disassemble, and structure is also very simple.

Embodiment
The Extensible wheel by a kind of easy disassembly to the present invention is described in further detail below.To make this hair
Bright purpose, feature become apparent, and the embodiment of the present invention is further described below in conjunction with the accompanying drawings.
As shown in Figures 1 to 10, installation extension type traveling wheel 100 is leaned on after a kind of steel of easy disassembly, including：Piston shoes
2nd, slide bar 6, push rod device and roller erecting device.Push rod device is installed on piston shoes 2 by locating clamp plate 5, and by inserting
It is spacing that pin plate 3 carries out top；Slide bar 6 is connected by flexural pivot and the adjusting screw rod of push rod device 1, and is slided in piston shoes 2；Roller
Roller 7 in erecting device is installed on slide bar 6 in the following, with the slip of slide bar 6 and flexible by wheel shaft 8；Slide bar 6 is in piston shoes 2
Slide, it declines scope as shown in figure 9, position when 6 strip of paper used for sealing of slide bar and 2 bottom blend stop of piston shoes contact is the decline of slide bar 6
Extreme position, that is, the extreme position that roller stretches out.
As shown in Figure 5, Figure 6, piston shoes 2, pin hole is provided with the first piston shoes riser 2-1 and the second piston shoes riser 2-2 tops
