Technical field
This utility model relates to a kind of water conservancy project cavern con struction scissor-type mobile lifting platform, particularly to a kind of with self-balancing and from being fixedly mounted with the scissor-type mobile lifting platform put。
Background technology
In water conservancy project cavern excavation is constructed, present typical tunnel excavation effect, very easily cause caving in, falling the security incident generation that the geology such as block are destroyed；And constantly raise along with work cycle increases excavation face, adopt and during traditional level altitude operation frame, need continuous padded frame body so that bore that quick-fried operating cycle constantly extends, pore-creating direction is difficult to control to, safe work efficiency is low, construction cost is high。In order to ensure the realization of construction safety, progress, quality and cost objective, excavation is optimized with supporting parameter design and research and develop a kind of ensure construction safety, be easy to the construction operation safety device that operation is closely connected propose in the urgent need to。
Summary of the invention
In order to overcome existing level altitude operation frame deficiency in construction, this utility model provides a kind of self-balancing scissor-type mobile lifting platform, can realize the quickly movement in cavern excavation process, freely lift；And equipment has self-balancing, certainly firm function, a construction environment safely and efficiently can be provided for workmen。
This utility model solves its technical problem and be the technical scheme is that a kind of self-balancing scissor-type mobile lifting platform includes low bottom-disc, top bottom-disc, and top bottom-disc is connected to low bottom-disc by scissor-type lifting mechanism, and low bottom-disc is provided with road wheel；
Described top bottom-disc is provided with protective platform, equalizing feature, moves parts from stabilizing components, platform, described platform moves parts and includes platform line slideway, platform oil cylinder, platform line slideway, platform oil cylinder are located on top bottom-disc, platform oil cylinder is mechanically connected with protective platform, and protective platform is located on platform line slideway and can slide along platform line slideway under the driving of platform oil cylinder；Equalizing feature includes balance weight, balancing cylinder, balance line slideway, balance line slideway is located on top bottom-disc, balance weight slides along balance line slideway under the driving of balancing cylinder, the described firm line slideway that includes being arranged symmetrically with from stabilizing components, double-piston rod-type double; two go out rod oil cylinder, going out at double-piston rod-type pair and respectively set a strut on two power output shafts that rod oil cylinder is symmetrical, power output shaft is the firm line slideway slip in edge under the double; two rod hydraulic oil cylinder driving of double-piston rod-type；
What described platform line slideway, balance line slideway, firm line slideway were parallel to each other is located on top bottom-disc。
Further, low bottom-disc is provided with hydraulic leg。
The beneficial effects of the utility model are: protective platform is connected with top bottom-disc by balancing line slideway by platform line slideway, balance weight, and balancing cylinder, platform oil cylinder are all singly go out rod oil cylinder, do synchronous relative motion during work；Being mounted with on top bottom-disc from securing device, after hoistable platform is raised to specified altitude assignment, double-piston rod-type pair goes out rod oil cylinder and makes bar motion, drives the support bar on power output shaft to stretch out, pushes against on cavern's wall。
By tradition fork type elevator increase being perpendicular to the locomotive function of direction of travel (longitudinal direction), add the scope of operation of platform；Set up again self balancing device, with the centre offset avoiding platform vertical misalignment to produce；Set up from securing device, strengthen the safety of platform operations and reduce platform rocking when operation。

In figure: 1. low bottom-disc, 2. scissor-type lifting mechanism, 3. top bottom-disc, 4. from securing device, 5. protective platform, 6. balance weight, 7. platform line slideway, 8. platform oil cylinder, 9. balancing cylinder, 10. balance line slideway, 11. struts, 12. firm line slideways, 13. double-piston rod-types pair go out rod oil cylinder。
Detailed description of the invention
Such as Fig. 1, in 2, a kind of self-balancing scissor-type mobile lifting platform includes low bottom-disc 1, top bottom-disc 2, and top bottom-disc 1 is connected to low bottom-disc 1 by scissor-type lifting mechanism 2, and low bottom-disc 1 is provided with road wheel；
Top bottom-disc 3 is provided with protective platform 5, equalizing feature, moves parts from stabilizing components, platform, platform moves parts and includes platform line slideway 7, platform oil cylinder 8, platform line slideway 7, platform oil cylinder 8 are located on top bottom-disc 3, platform oil cylinder 8 and protective platform 5 are mechanically connected, and protective platform 5 is located on platform line slideway 7 and can slide along platform line slideway 7 under the driving of platform oil cylinder 8；Equalizing feature includes balance weight 6, balancing cylinder 9, balance line slideway 10, balance line slideway 10 is located on top bottom-disc, balance weight 6 slides along balance line slideway 10 under the driving of balancing cylinder 9, in Fig. 4, the firm line slideway 12 that includes being arranged symmetrically with from stabilizing components, double-piston rod-type double; two go out rod oil cylinder 13, respectively setting a strut 11 on two power output shafts that double-piston rod-type pair goes out rod oil cylinder 13 symmetry, power output shaft goes out the firm line slideway 12 in edge under rod oil cylinder 13 drives at double-piston rod-type pair and slides；
In Fig. 3, what platform line slideway 7, balance line slideway 10, firm line slideway 12 were parallel to each other is located on top bottom-disc 3, platform oil cylinder 8 is located between two platform line slideways 7, outside two balance line slideways 10, being provided with double-piston rod-type pair between two firm line slideways 12 and go out rod oil cylinder 13, balancing cylinder 9 is located between two balance line slideways 10, outside two firm line slideways 12。
Preferably, low bottom-disc 1 is provided with hydraulic leg。
During work, hoistable platform moves to assigned work position, launches and rises hydraulic leg。When wheel leaves ground, lift scissors mechanism。After arriving assignment height, go out under the effect of rod oil cylinder 13 at double-piston rod-type pair from securing device strut 11, stretch out in opposite directions, hold out against hole wall；And together with scissors mechanism hoist cylinder, due to the effect of hydraulic lock by locked for platform at level altitude。Along with the increase of the scope of operation, protective platform 5 is under the effect of platform mobile device, longitudinally movable, and balance weight is also under the effect of balancing cylinder 8 simultaneously, moves towards along balance line slideway。The proportionate relationship that they move is set up by flow speed control valve。
Work complete, first make protective platform 5 return, then regain from securing device, then can be reduced podium level by scissors mechanism, finally regain hydraulic leg, it is possible to start next cycle of operation。
