Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 5, the present invention relates to a multiple-damping machine room-less elevator, which includes a car 15 located in a hoistway, a car frame for floating installation of the car 15, a winding motor 11 located at the top of the hoistway, a hoisting rope 12 for pulling and winding the car frame and the car 15 by the winding motor 11, two car top wheels 16 separately disposed at the top of the car frame and bypassed by the hoisting rope, the car frame includes a groove-shaped pillar 21 located at both sides, a hidden guide shoe 13 disposed in the groove of the pillar 21, the guide shoe 13 includes a groove-shaped shoe liner 31, a shoe base 32 half-surrounded on the side and back of the shoe liner 31, and a damping member 33 mounted between the back and side of the shoe liner 31 and the shoe base 32. The shoe 31 guides the up and down movement of the elevator car in cooperation with a guide rail installed in the hoistway. In the elevator cage without a machine room, the return rope wheel is arranged on the top of the cage and the cage frame of the elevator to form the top wheel 16, so that the requirement of the depth of a pit can be reduced. The guide shoe is arranged in the upright post 21, so that the requirements on the depth of a pit and the height dimension of the top layer are reduced by 150mm respectively, and the guide shoe can avoid the hauling rope 12 to avoid interference. Change the base, change mounted position, increase damper 33 for it can install in car stand 21 to lead boots, and has the shock attenuation effect, effectively eliminates noise and shake.

To eliminate the resonance and noise generated by the hard guide shoe and the vibration generated when the guide shoe passes through the guide rail interface. The guide shoe is additionally provided with soft damping rubber at the left side, the right side and the back of the shoe liner 31. When the car 15 inclines slightly, the shoe lining 31 can compress rubber, so that the shoe lining 31 of the guide shoe 13 can generate an angle, the whole shoe lining 31 surface is tightly attached to the guide rail to rub, the forced friction contact area is increased, and the noise and vibration are effectively reduced.

In particular, the damping member 33 is a damping rubber, which provides a flatter and larger cushion area, and is more stable and durable.

As shown in fig. 4, 5 and 6, the shock absorbing members 33 on both sides are fixedly connected to the shoe lining 31 to buffer and protect the shoe lining 31, so that the shoe lining 31 can change its inclination angle to adapt to the situation when swinging under the action of external force, thereby reducing the shaking and improving the stability, the shoe base 32 is provided with a limiting member 35 for limiting the sliding amplitude of the shoe lining 31 to prevent the shoe lining 31 from sliding out, and the limiting members 35 are located above, below and on the front side of the shoe lining 31. The shock absorbing member is sheet-shaped or block-shaped.

Specifically, the limiting member 35 is an L-shaped limiting piece, and two bent end portions are respectively used for mounting and limiting the shoe lining 31.

Preferably, the shoe base 32 is provided with a side baffle 36 forming a groove shape, the side baffle 36 limits the shoe lining 31 and the shock absorbing member 33 playing a buffering role, a screw 39 is arranged through the side baffle 36, the front end of the screw 39 extends into two ends of the block shock absorbing member to form a limiting stop rod, the up-down moving range and the back-and-forth moving range of the shock absorbing member are limited, the stability of the whole structure is improved, and the shoe lining 31 is prevented from being moved by too large amplitude and is adsorbed by the guide rail to be thrown away.

As shown in fig. 2 and 3, the car frame further includes a top beam 22 fixedly connected to the top end of the upright 21, a secondary beam 23 connected to the top beam 22 in a floating manner, a bottom beam 27 fixedly connected to the bottom end of the upright 21, and a chassis 26 installed on the bottom beam 27 in a floating manner, wherein a load-bearing car bottom 25 of the car 15 is installed on the chassis 26 in a floating manner, and the car top wheel 16 is installed on the secondary beam 23. The floating installation has a buffer effect between the components, reduces the transmission of vibration, increases the running stability of the elevator, and promotes the comfortable sensation of standing in the lift car 15, so that the elevator is suitable for serving as a passenger elevator. The double-upper-beam structure formed by the combination of the top beam 22 and the auxiliary beam 23 increases the shock absorption effect for the elevator, can weaken the vibration transmission of friction between the car top wheel 16 and the steel wire rope (the hauling rope 12) when the car 15 runs, and also weakens the resonance of a counterweight and a main machine brought by the steel wire rope. The connection surfaces (bearing car bottom) of the bottom beams 27 and the chassis 26 and the connection surfaces (bearing car bottom) of the chassis 26 and the car bottom 25 are provided with shock absorbing pieces 28/29 for floating installation, and the shock absorbing pieces can be polyurethane shock absorbing rubber blocks 28 or shock absorbing rubber sheets 29 serving as spacing cushion layers and can weaken the vibration transmitted by friction between the guide rails and the guide shoes 13. Thus, the car 15 can have triple shock absorbing functions by absorbing shock between the platform 25 and the chassis 26, absorbing shock between the bottom beams 27 and the chassis 26, and absorbing shock between the top beams 22 and the sub-beams 23. Finally, resonance and shaking are weakened through the effect of the damping rubber, so that the elevator is comfortable, stable and quiet in operation. The chassis 26 may be in the form of a shelf structure.

Specifically, an elastic buffer is arranged between the top beam 22 and the secondary beam 23, an elastic buffer is arranged between the bottom beam 27 and the chassis 26, and an elastic buffer is arranged between the car 15 and the chassis 26. Further, the elastic buffer is a buffer rubber pad (which may be a shock-absorbing rubber block 28 or a shock-absorbing rubber sheet 29). The top beam 22 and the secondary beam 23, the bottom beam 27 and the chassis 26, and the car 15 and the chassis 26 are spaced by using damping members, specifically, polyurethane rubber pads or rubber gaskets.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, therefore, the invention is not limited thereto.
