A kind of support holder structure of vertical lift
The present invention relates to a kind of support holder structures, and in particular to a kind of support holder structure of vertical lift.
Equipment in engineering machinery field, which generally is, to be met a certain construction requirement and designs, it is most common have crane,
Loading machine, bull-dozer etc..Different equipment includes driver's cabin, for meeting driver safety, cosily carrying out construction operation, no
Same engineering field, function of the driver's cabin in structure design is also different, under normal circumstances, the equipment such as loading machine, bull-dozer
Driver's cabin is all centrally arranged, is fixed on main machine structure, is working in transportational process, driver's cabin remains at same position
On.And for hoisting machinery, since the weight and size of crane itself are larger so that exist in the transition transportational process of equipment
Therefore ultra-wide, overweight limitation have to consider integrally-built width, height dimension and weight in the design process.
In lifting equipment, the height of operating room is the bottleneck of transport under normal circumstances, as long as by the height of operating room
Degree reduces, and the shipping height of vehicle can reduce, and is required to meet ordinary road transport.
Under current technical status, domestic crane-men's house is generally designed using collapsible, level altitude, that is, is being risen
It remains unchanged in operating room vertical direction during heavy-duty machine is transported and worked, is wanted by being folded to host front end to meet width
It asks.At abroad, to meet the limitation of crane shipping height, limitation of the driver in some specific operation downward views is solved, is occurred more
The operating room lifting structure of connecting rod and hydraulic cylinder composition.The support holder structure being vertically moved up or down using telescopic arm and hydraulic oil cylinder driving, mesh
Before, do not occur with foreign countries at home.
In view of the above existing problems in the prior art, the present invention provides a kind of support holder structure of vertical lift, pallet lifts
Convenient, lifting levelness keeps preferable, simple in structure, easy to maintenance.
To achieve the goals above, the technical solution adopted by the present invention is：A kind of support holder structure of vertical lift, including support
Disk and operating room, operating room are arranged above pallet, further include telescopic arm and swing arm, and telescopic arm is arranged in the side of pallet, pendulum
Arm is connect with telescopic arm, and swing arm is provided with guide pad close to a side-lower of pallet, and the lower section of pallet is close to the position of guide pad
Cushion block is set, and cushion block is in contact with guide pad.
Further, the telescopic arm quantity is two, and two are oil cylinder or Telescopic-cylinder arm, and two flexible
Arm is arranged at the rear side of pallet, and swing arm is connect with two telescopic arms.
Further, two telescopic arms are located at the rear side of pallet and the position close to two sides.
Further, the cushion block is adjustable, is made of bolt, brake pad and welded plate, is opened in the middle part of welded plate
If threaded hole, being welded with tray bottom at the top of welded plate, bolt is connect by threaded hole with welded plate, and the one of brake pad and bolt
End connection, brake pad are contacted with guide pad.
Further, the swing arm is connect by axis pin with telescopic arm.
Further, a limited block is respectively arranged in the upper and lower part of the telescopic arm.
Lift pallet of the present invention using complicated support and lifts structure compared with prior art, only pallet with
The telescopic arm structure of built-in oil cylinder is set in the structure of swing arm connection；Secondly, telescopic arm structure, contain telescopic arm itself with it is interior
Two parts of oil cylinder are set, telescopic boom cylinder structure takes into account bearer properties and kinetic characteristic, meets the application of special dimension；Again
Secondary, telescopic arm structure of the present invention is simple, practical, only includes the movement of upper and lower directions, and have guide pad and oil in the movement direction
The included mechanical limit point of cylinder so that the sports safety of oil cylinder is reliable, caused by avoiding sensor detection movement and position
The problem of data inaccuracy；Cushion block is contacted with guide pad face always, and during ensureing that telescopic arm moves up and down, pallet is located always

Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figures 1 to 4, the present invention includes pallet 1 and operating room 2, and operating room 2 is arranged above pallet 1, further includes
Telescopic arm 3 and swing arm 4, telescopic arm 3 are arranged in the side of pallet 1, and swing arm 4 is connect with telescopic arm 3, swing arm 4 close to pallet 1 one
Side-lower is provided with guide pad 5, and cushion block 6 is arranged close to the position of guide pad 5 in the lower section of pallet 1, and cushion block 6 connects with guide pad 5
In order to ensure pallet 1 lift stability, 3 quantity of telescopic arm be two, and two be oil cylinder or
Telescopic-cylinder arm, oil cylinder or cylinder are built in telescopic arm 3, and two telescopic arms 3 are located at the rear side of pallet 1 and close to two
The position of side is arranged, and swing arm 4 is connect with two telescopic arms 3, and two telescopic arms 3 ensure that pallet 1 lifts stability, Bu Huifa
Raw shake tilts.
The cushion block 6 is adjustable, as shown in Fig. 2, cushion block 6 is made of bolt 61, brake pad 62 and welded plate 63,
63 middle part of welded plate opens up threaded hole, and 63 top of welded plate is welded with 1 bottom of pallet, and bolt 61 passes through threaded hole and welded plate 63
Connection, brake pad 62 are connect with one end of bolt 61, and brake pad 62 is contacted with guide pad 5, and friction is adjusted by rotating bolt 61
The front and back position of block 62, during ensureing that telescopic arm 3 moves up and down, pallet 1 is in horizontality always.
The swing arm 4 is connect by axis pin with telescopic arm 3, and telescopic arm 3 is in hinged state with swing arm 4, facilitates telescopic arm 3
Flexible, a limited block is respectively arranged in the upper and lower part of the telescopic arm 3, is rising to peak or is dropping to minimum point
When, it limits oil cylinder and continues to move, to accurately controlling pallet 1.
Working condition is as shown in Figure 1, the oil cylinder of telescopic arm 3 is in contraction state, at pallet 1 and operating room 2 at work
Height, meet operating personnel operating room 2 normal work；Under travel position as shown in figure 5, to reduce the height of operating room 2
Degree, 3 oil cylinder of telescopic arm reaches bottom, to reduce the height of pallet 1 and operating room 2, to meet wanting for road transport regulation
It asks；In 3 telescopic process of telescopic arm, the brake pad 62 on cushion block 6 is contacted with 5 face of guide pad in swing arm 4 always, is ensured flexible
During arm 3 moves up and down, pallet 1 is in horizontality always；The present invention can drop operating room 2 under travel position
To minimum point, meet limitation requirement of the highway transportation to height, in the operating condition, then operating room 2 promoted and arrives normal level,
Meet requirement of the driver to the visual field under working condition, easy to use, switching is freely.
