Description

A kind of traction machine and the home lift for being provided with the traction machine

Technical field

The utility model belongs to elevator technology field, and in particular to a kind of traction machine and the household electric for being provided with the traction machine Ladder.

Background technology

With the progress of society, economic growth, requirement more and more higher of the people to quality of the life, particularly individual's Home lift generally existing is installed in villa or house.Existing private villa or residential houses are typically all pitched roof knot Structure, top of building space can not possibly install computer room, and its to be used to install the space of elevator very limited, especially to having made When transformation installation elevator is carried out on the basis of good private villa or residential houses, its space is even more limited, only stair turning The space vacated can install elevator.The length of the hoistway of this building is all fixed, how to have made full use of this One of the problem of limited space is home lift installation urgent need to resolve.

As shown in Figure 1 and Figure 2, existing home lift mainly includes traction machine, car 2, counterweight 3, car guide rail 4, counterweight Guide rail 5, machine frame 6, crossbeam 7 etc., described traction machine include traction machine body 1, for supporting fixed traction machine body 1 Footing 1111 and the traction sheave 120 that moves up and down of driving car 2, the top of the car guide rail 4 be provided with for installation lead boots, The crossbeam 7 of the parts such as safety component, car top fixed mechanism, in order that car 2 is higher as far as possible, crossbeam 7 need to set higher, In order that the length in the gate direction of car 2 is as long as possible, be arranged on the counter weight guide track 5 of the side of car 2 then need to take it is less Space, the home lift traction machine body 1 in top are installed on machine frame 6, and described traction machine typically uses two Kind structure, one kind is dual-support structure, " one as involved by Chinese utility model patent Authorization Notice No. is CN204917567U Kind of villa elevator ", Chinese utility model patent Authorization Notice No. be disclosed in CN206069165U " a kind of elevator is draged with horizontal Draw machine " and a kind of " home-use elevator traction for being provided by CN205709387U of Chinese utility model patent Authorization Notice No. The support footing 1111 of machine ", wherein traction machine body 1 is distributed in the both sides of traction sheave 120, specifically as shown in Fig. 2 traction sheave 120 center wider width of the middle part of width and traction machine body 1 before and after car 2, crossbeam 7 is also close to car 2 The middle part of width, the footing 1111 and its installation bolt of traction machine easily interfere with crossbeam 7, in order that footing 1111 Do not interfered with crossbeam 7, will stagger certain position between machine frame 6 and crossbeam 7, will certainly so increase car top Away from the headroom height between roof, if hoistway height is limited, the position of machine frame 6 or crossbeam 7 can only be reduced, if reducing horizontal The height of beam 7, then the height of car 2 will be reduced, if reducing the height of machine frame 6, the length in the gate direction of car 2 will be reduced Degree, no matter any method, can not all obtain length and width high spatial and arrange comparatively ideal car 2.

Another structure of traction machine is cantilever design, as Chinese utility model patent Authorization Notice No. is " a kind of drag device of household ladder " mentioned by CN205739897U, Chinese utility model patent Authorization Notice No. is " a kind of villa traction machine " that CN205034930U is illustrated, the support footing 1111 of wherein traction machine body 1 is all located at draging The side of running wheel 120, it is specific as Fig. 3 and Fig. 4, the wherein footing 1111 of traction machine body 1 are located at traction sheave 120 away from crossbeam 7 Side, will not be interfered with crossbeam 7, but whole traction machine body 1 is arranged in hoistway close to the front portion of gate, traction machine The brake side of body 1 and the distance of well enclosure are reduced by, and are so not easy to repair and are detected.

In order that the inner space of car 2 is as far as possible greatly it is necessary to making full use of limited hoistway space to arrange that installation is draged Draw the parts such as machine body 1, car 2, counterweight 3, car guide rail 4, counter weight guide track 5, safety device, ensure elevator safety and work( On the basis of energy property so that elevator ride is more comfortable, and installation and maintenance are more convenient.
