Description

A kind of single-column cantilevered household lift

Technical field

Invention relates to a kind of villa household lift [B66], and its structure is single-column cantilever, and Backpack type works: lightweight car is fixed on the sedan-chair frame [12] of L-shaped, and L-type sedan-chair frame depends on the T-shaped guide rail [7] that column both sides are installed；Sedan-chair frame upper and lower side is respectively provided with three rolling guide shoes along T-shaped guide rail；Column top is equipped with traction machine [9], limiter of speed [4], and pull rope is chain [13], and miniature weight [11] is contained in vertical column square tube；Sedan-chair frame side adds eccentric contract block clamp [8], and when disconnected rope, eccentric contract block clamp are stuck on column and protect car not drop；Polyurethane bumper absorber [15] is installed on the lower end side of L-type sedan-chair frame；Switch board is the VVVF frequency-converting speed-governing control system that 220V power supply is powered, and is arranged in top wall；The feature of this equipment is compact conformation, safety guarantee, and scheme is novel, has substantially accomplished at machine room, runs without the elevator under counterweight state。

Background technology

Conventional elevator structure is traction-type, and cage side takes rail as the leading factor, and counterweight side is secondary guide rail, and during traction, car and counterweight are each run up and down by the track retrained in orbit；Running safety for ensureing simultaneously, be provided with pit buffering, top prevents the upper super protection rushed to summit, and prevents the safety tongs overspeed protection fallen；These safety measures have been included GB in and have been enforced standard, and Just because of this, elevator was once seeming very complicated, and particularly pit depth and machine room height make civil engineering cost increase much, limit the development of villa household lift to a certain extent。

Chinese patent 200720094481.2 discloses the household lift of a kind of L-type, single-column support traction；It has certain creativeness, but counterweight is still configured according to a conventional method, and result of which still must consider pit depth and headroom height problem；That is: although the existence of counterweight solves traction equilibrium problem, but the side effect brought to be floor space big, effective requirement of shelter at the pendant end of rushing to summit is higher。

The purpose of patent of the present invention is in that to design a kind of brand new elevator without counterweight, machine room；Of course not be placed in safety ignore and for it, but first solve the safety precautions of new structure, when the experiment of its form reaches safety criterion, consider again equipment operational feasibility: for chain drive scheme, it has good anti-traction sheave skidding ability, and counterweight thus can be down to the minimum only weight of several kilograms；Learning through experiment: in 1:1 traction situation, load 2000Kg, counterweight side only needs 20Kg just can complete traction；It is best selection that so good result is applied to household lift。

Summary of the invention

A kind of single-column cantilevered household lift: lightweight car is fixed on the sedan-chair frame [12] of L-shaped, and sedan-chair frame upper and lower side is respectively provided with three rolling guide shoes, and sedan-chair frame lower end position is also equipped with safety tongs [14], by limiter of speed [4] enable action；T-shaped guide rail is installed in column both sides；Column top is equipped with traction machine [9], limiter of speed [4], and pull rope is chain [13], and miniature weight [11] is contained in vertical column square tube；Sedan-chair frame side adds eccentric contract block clamp [8], and when disconnected rope, eccentric contract block clamp are stuck on column and protect car not drop；Polyurethane bumper absorber [15] is installed on the lower end side of L-type sedan-chair frame；Switch board is the VVVF frequency-converting speed-governing control system that 220V power supply is powered, and is arranged in top wall。

The scheme of patent of the present invention is realized in

Utilize the superpower anti-skidding ability of chain, in without counterweight situation, realize elevator traction；Time up, traction is that load adds that car sedan-chair frame is conducted oneself with dignity, and the load of 400Kg, the speed of 0.4M/S, the traction machine of 1.2Kw just can complete；Time descending, load is done work to traction machine, the dynamic braking unit of converter complete energy conversion, keep elevator even running；Because speed is relatively low, pit buffer distance is only 0.3+0.035V²M (), is about 0.3 meter, close to without pit。And buffer is placed in side, and cage bottom space is better ensured；For preventing disconnected rope, also adding eccentric contract block clamp [8] in sedan-chair frame side, when disconnected rope, eccentric contract block clamp are stuck on column and protect car not drop；Upper sheaf space be can be made smaller, because the reason of elevator deadweight occurs up automatic brake never。

Beneficial effect

Compared to the prior art, having the advantages that of patent of the present invention, save hoistway space, from total equipment complex cost and family's civil engineering restriction, equipment cost performance is at a relatively high, and the suitability is very strong。

Applicating example has the villa of a client, its Top height 3300, and hoistway cross section is 1400*1400；This environment [Fig. 6], the elevator of standard specifications cannot be installed and come into operation, but adopts this patent scheme, it may be achieved the elevator arrangement of 400Kg。4 conditions of headroom height that GB7588-2003 GB 5.7.1.1 requires; it it is the safety precautions for the traction elevator having counterweight; because this patent does not have counterweight; the release of inertia energy source that car does not rise voluntarily, thus its first, the second; fourth condition can be avoided; only considering that third condition, sedan-chair top overhead must have a human body being not less than 0.5*0.6*0.8 to hide space, this condition substantially can meet；Above structural design carries out exclusively in user's special environment situation, still requires to stay by GB enough enough headroom heights and pit depth under normal circumstances。
