Definitions
- the present invention relates to a traction lift for passengers or goods and more particularly to a traction lift of the type with load car hoisting machine located beside the top of the hoistway (also termed "Traction Top Side” or TTS type).
- the general purpose of the present invention is to remedy the above mentioned shortcomings by making a available a traction lift with car hoisting machine located beside the upper end of the hoistway and which, in addition to obviating the prior art shortcomings, would display at least one of the following advantages:
- the traction lift according to the invention is of the type with load car hoisting machine located beside the top of the hoistway, and in which are a fixed frame supporting the hoisting machine, a counterweight and movable frame supporting the car, a traction pulley for operation of the hoisting ropes and a diverting pulley designed to locate the vertical section of the counterweight support ropes in the desired position, guide tracks for guiding the movement of the movable frame and counterweight, and brackets for fastening the tracks to the hoistway walls. It is characterized in that:
- the above mentioned movable frame presents a cantilever structure and comprises horizontal support beams for the car base and a pair of vertical beams abreast of one of the car walls,
- the movable frame and counterweight guide tracks are located near a same hoistway wall
- FIG.1 shows a vertical cross section view of a machine room in accordance with the present invention with the car in upper limit-stop position
- FIG.2 shows a horizontal cross section view of the hoistway and car of
- FIG 1 , FIG.3 shows a perspective view of a movable car-rack frame in accordance with the present invention
- FIG.4 horizontal cross section view of the machine room of FIG 1
- FIGS. 5 and 6 show side and front views of the fixed frame supporting the hoisting machine of FIG 1
- FIG.7 shows a variant of FIG 5 concerning the different positioning of the hoisting machine.
- FIGS. 1 , 2 and 3 show a preferred embodiment of the traction lift in accordance with the present invention displaying a housing ("car") 1 for passengers and goods to be conveyed, fastened to a movable frame 2 (car-rack frame) running along guide tracks 31 ,32 arranged at its sides.
- the car rests on the movable frame through a base 11 and along one of its walls.
- the car can have one or more accesses 12 arranged on any of its sides except the side in contact with the frame.
- the movable frame presents a cantilever structure.
- the movable frame has as its main components two beam pairs with each pair made up of a horizontal beam 21 and a vertical beam 22 arranged according to an L position.
- the two horizontal beams act as a support for the base 11 of the car while each vertical beam accommodates at its ends two shoes 24, 25 designed to hold the movable frame on its guide tracks 31 , 32.
- the two horizontal beams are connected together by two crosspieces 26 which give additional stiffness to the system.
- a third crosspiece 27 connects the upper end of the two vertical beams.
- the first two beams 26 also support a beam 29 to which are anchored (at its intersection with the vertical plane passing through the tracks 31 , 32) the hauling ropes.
- the third crosspiece also acts as a support for two plates 28 with L cross section serving for the upper fastening of the car.
- the hoisting machine 5 is positioned on a fixed frame 6 supported by four pillars constituted by the movable frame guide tracks 31 , 32 and by another pair of tracks 33, 34 guiding the counterweight 7. Said pillars depart from beneath said frame 6 to descend to the bottom of the hoistway (the system "pit").
- the two left-hand pillars 31 , and 33 are connected together and to the wall behind through metal brackets like no. 35 of FIG 2 while the two right-hand pillars 32, 34 are connected together and to the wall behind through metal brackets like no. 36 of the same figure.
- the frame 6 is fastened to the tracks 31 , 32, 33, 34 through bolts and blocks 37 welded outside the upper end of the tracks.
- buffers 38 placed between the blocks 37 and frame 6 as well as buffers 20 placed between the car base and the car-rack frame.
- On the wall behind the above mentioned pillars at the height of the frame 6 is an opening designed to allow partial emergence of the frame 6 and the machine 5 from the hoistway. This opening communicates with an adjacent compartment 8 (machine room) in which is located (at the point considered most appropriate) the electronic control system (control panel) 81 of the system.
- a stop device (parachute, not shown in the figures) capable of mechanically stopping the car-rack frame by means of blocks clamping on the guide tracks. Operation of this stop device is caused by a speed limiting device 9 (FIG 3) having pulleys 43, 44 (with the pulley 43 having a microswitch operated when the centrifugal force generated by rotation exceeds a certain value, and with the pulley 44 having a tensioning device) whose peripheral speed is held equal to that of the car by means of a cable 45 fastened at one of its points to the car-rack frame.
- a speed limiting device 9 FIG. 3
- the car-rack frame guide tracks must therefore be sized not only in relation to the peak load to which they are subjected by the forces exerted by the car-rack frame on its tracks and the bending moment exerted by the shoes 24, 25 but also in relation to the dynamic stresses to which they would be subjected in case of parachute operation.
- the speed limiter 9 is located in the high part of the hoistway at the level of the frame 6 while, as already explained, the control panel 81 is located in the machine room. Inspection and maintenance thereof are thus easy and safe as is operation in case of emergency control to free passengers trapped in the car.
- the connection opening between the hoistway and the machine room allows easy inspection of the speed regulator.
- Rotation of the hoisting machine motor is controlled by an encoder allowing extrapolation of the position and speed of the car in the hoistway.
- a device for regulation of the level and frequency of the power supply voltage allows fine adjustment of motor rotation speed.
- a variant could concern arrangement of the machine 5 on the frame 6.
- said machine could be positioned with its motor axis arranged vertically as indicated in FIG. 7 instead of with its motor axis arranged horizontally as shown in FIG. 5. This would have the advantage of better practicability of the machine room or the possibility of further reduction of its occupied space.
