Description

A kind of stilt formula elevating device

Technical field

The present invention relates to mechanical device field of ascending a height, especially a kind of stilt formula elevating device.

Background technique

Usually eminence is needed to take object in life and production, such as picks hydropower installation, house decoraton, cleaned with wall body door or window, Fruit-picking and pendulum takes commodity etc. to ascend a height operation on shelf, usually we are using ladder, lifting platform as tool help people Reach eminence.

Traditional ladder will often select long ladder or short ladder according to the height of setting when in use, what is unconditionally selected In the case of, the normal handy long ladder of work present in short, long ladder is not only heavy, and too long ladder bars interfere user's operation and safety. Ladder is too short, does not reach working face, is unable to complete the awkward situation of operation.Low change height when high when being required during operation, People must climb up and climb down.If all around to change operating position, it must swash from ladder, carry on one's shoulders or with both hands after moving ladder Climbing up again again can just work on.Need not consuming for user's physical strength is caused, is dallied over one's work the time, operating efficiency is reduced.Ladder The mobile difficulty of son, lifting platform, ladder or lifting platform with locomotive function are needed by the outer of other staff or driving mechanism Power could be completed to move.

Stilt are that two legs of professional fix a root long bar respectively, and as leg extension, professional can using stilt With walking, it has been found that stilt, which are that one kind is transportable, not to be needed to want environment compared to ladder stilt by external force tool Ask low, but stilt need just to can be used by long-term training, higher-height upper stilt and lower stilt can be by other people Member's auxiliary or aloft upper and lower stilt of standing.

Referring to Figure 1, the Chinese utility model patent of notification number CN201981993U discloses a kind of stilt formula and can increase Drop step moves ladder, is made of two mutual disjunct ladder bars.The support rod of supporter is sleeved on group in the lifting bore of lifting body At ladder bars.Supporter includes support rod and stabilizer, and stabilizer is made of steadying plate and stable pin.Lifting pipe with by manipulator Handle, connecting rod, spring, control box, idler wheel, elastic slice, the lift control system of removable pin synthesis and foot pedal and cingulum constitute lifting Body.

Fig. 2 is referred to, publication No. discloses a kind of scissor lift platform for the Chinese invention patent of CN104627899Z, including Pedestal 100, elevating mechanism 200, lift drive mechanism 300, load carrier 400 and pressure sensor 500.Pedestal 100 is located at institute The scissor lift platform bottom is stated, there are 4 mounting holes 101 thereon convenient for connecting with bottom surface or other equipment.Elevating mechanism 200 be by Two sets are identical and be parallel to each other, and the multilayer for being correspondingly arranged at 100 two sides of pedestal is formed in the elevator component of X-shaped, The elevator component of same layer is made of two hinged connecting rods 201 for making it have revolute pair in middle part, adjacent two layers liter Descending mechanism part is hinged by the linkwork that 201 both ends of connecting rod are arranged in, a company in bottom elevator component One end of bar 201 and pedestal 100 are hinged.Lift drive mechanism 300 is set on the pedestal, two sets of multiple layer up-down mechanism members It is intermediate.

It needs in technology, stilt type adjustable lifting walking ladder user, which needs that balance could be grasped by long-term training, to complete Lifting, while occupied space is big.

The shortcomings that scissor lift platform is：Weight is big, price is high, needs electricity consumption, moving range small.
