Background

At present, the elevator for villa in market mainly comprises a hydraulic villa elevator, a screw type villa elevator, a forced driving villa elevator and a traction type villa elevator, wherein the hydraulic villa elevator utilizes oil pressure to enter a hydraulic elevator cylinder, so that a plunger moves linearly and drives an elevator car to move up and down. The oil pump motor has high noise, low lifting speed and oil pollution caused by leakage of the sealing ring of the piston of the hydraulic oil cylinder. The screw type villa elevator utilizes the elevator to drive the nut to rise and fall relative to the screw rod in a rotating way, and the nut drives the elevator car to move up and down. No steel wire rope and counterweight are arranged, the well utilization rate is high, but because the steel wire rope and the counterweight are driven by the screw and the nut in a matched mode, the operation noise is high, the lifting speed is low, the abrasion of the screw and the nut is high, and the maintenance cost is high. The forced driving villa elevator makes the lift car move up and down by winding steel wire rope or steel belt with winding machine fixed in the well or the lift car. The elevator has the advantages that no counterweight exists, the shaft utilization rate is high, but because the elevator drives the car to operate by winding the steel wire rope through the winch, the operation noise is high, the hoisting height is limited by the rope containing amount of the winding drum, the abrasion of the rope groove and the rope belt is high, and the maintenance cost is high. The traction type villa elevator drives the lift car and the counterweight to move up and down through the traction rope. The running speed is faster, but the elevator is provided with a counterweight and a traction cable, the well arrangement is complex, the occupied space is large, the well utilization rate is low, the abrasion of a traction sheave rope groove and the traction cable is large, and the maintenance cost is higher. The self-driven elevator directly drives the elevator car to move up and down by utilizing the driving wheel arranged on the elevator car, a counterweight, traction or traction cable is not required to be arranged, the well arrangement is simple, the well utilization rate is high, the well arrangement is attractive, and the lifting speed and the lifting height are not limited; the tire friction driving wheel is adopted for driving, the tire can reduce vibration and noise, the abrasion is small, the noise is low, the operation is stable and comfortable, and the maintenance cost is low.

Here, the wedge blocks 20 on both sides are all provided with the driving units 30, under the load action of the car 200, the wedge seats 10 on both sides respectively press down the wedge blocks 20 on both sides, so that the driving wheels 31 of the driving units 30 on both sides compress the elevator guide rail positioned in the middle, and thus, the driving units 30 can obtain corresponding friction force by virtue of the compression force between the driving wheels 31 and the elevator guide rail, and lifting driving is realized. Referring to fig. 2, the mating bevel between the wedge shoe 10 and the wedge block 20 is inclined toward the middle from bottom to top.

In another embodiment of the application, a wedge shoe 10, a wedge block 20 are arranged on each side of the elevator guide rail, and the wedge blocks 20 on the same side and the wedge shoe 10 have a sliding fit. A driving unit 30 is arranged on the wedge block 20 on the first side, and a freely rotatable guide wheel 40 is arranged on the wedge block 20 on the second side; the wedge shoes 10 on both sides respectively press down the wedge blocks 20 on both sides, so that the driving wheel 31 and the guide wheel 40 of the driving unit 30 respectively press the elevator guide rail positioned in the middle from both sides.

The yielding gap 11 is formed on the wedge-shaped seat 10, so that the driving unit 30 can be conveniently arranged, the arrangement size of the whole lifting driving assembly 100 in the vertical direction is reduced, and the structure is more compact.

Referring to fig. 1, in an embodiment of the present application, a pre-tightening bolt 12 is installed on the wedge base 10 to be adjusted in an up-down thread, the pre-tightening bolt 12 is located at the bottom of the wedge block 20, and the wedge block 20 is pressed upward by pressing the wedge block 20 upward so that the wedge base 10 is pressed upward by the wedge block 20. The pretension bolt 12 effects an initial pressure on the drive wheel by pushing up on the wedge. When the elevator is provided with a plurality of groups of lifting drive assemblies 100, the pretension bolts 12 realize uniform load adjustment of the plurality of groups of lifting drive assemblies 100. Further, an elastic element can be arranged on the pre-tightening bolt 12 to elastically compress the wedge block so as to buffer pressure fluctuation in the movement process.

Illustratively, referring to fig. 4, a first guiding and spacing fit a, a first guiding and spacing fit b, and a first guiding and spacing fit c are circumferentially arranged around the rotation of the drive wheel 31. The first guiding and limiting fit a and the first guiding and limiting fit b are simultaneously inclined sliding fit, and are used for realizing sliding fit between the wedge block 20 and the wedge seat 10. It should be understood that the labels a, b, c in fig. 4 are only schematically shown in three positions of guiding limit fit.

Specifically, three limit matching designs are adopted, and relative to single-position and two-position guide limit, more stable limit guide can be formed, the effect of dispersing stress is achieved, the guide limit of the wedge block is more stable, the deformation caused by the influence of load is reduced, the deformation of related connecting parts can be reduced, the driving wheel can be more uniformly pressed against the rail, and the pressure distribution of the driving wheel is more uniform. Meanwhile, the three limit matching designs can reduce the contact force of the guide limit, so that the sliding is smoother, and the blocking and the abrasion are reduced.

In addition, it should be noted that a greater number of guiding and limiting fits, e.g. 4, 5, 6, 7, 8, 9, … …, may be provided between the wedge shoe 10 and the wedge block 20. Fig. 4 and 5 only show the technical solution in which three guiding limit fits are provided between the wedge shoe 10 and the wedge block 20.

Specifically, here, the sliding portion 21 of the wedge block 20 is brought into a sliding fit relationship by being inserted into the guide groove 13 of the wedge shoe 10. When the lift driving assembly 100 moves up and down along the elevator guide rail, the sliding part 21 of the wedge block 20 slides in the guide groove 13 of the wedge base 10, and the wedge block 20 is difficult to separate from the wedge base 10 due to the limitation of the shape of the guide groove 13, so that the lift driving assembly is more stable and reliable.

Referring to fig. 3, in some embodiments, the connection between the wedge shoe and the car is on the same side of the wedge shoe as the drive sheave. Here, the installation surface of the wedge-shaped seat and the driving wheel are positioned on the same side, so that the moment generated by the pressing force of the driving wheel on the installation structure can be reduced.

Referring to fig. 6, the driving unit 30 includes a driving wheel 31, a driving source 32, and the driving source 32 is configured to drive the driving wheel 31 to rotate and output power.

Referring to fig. 7 and 8, the embodiment of the present application also provides a villa elevator including a car 200, an elevator guide rail, a guide mechanism 400, and the elevation drive assembly 100 provided in the former part. The elevation drive assembly 100 is used to drive the car 200 up and down along elevator guide rails. The car 200 is used for loading people or goods and for vertically transporting pedestrians or goods. The self-driven elevator directly drives the elevator car to move up and down by using a friction driving wheel arranged on the elevator car.

In one embodiment of the application, the elevator guide rail is formed of a first type of rail 50 for use in conjunction with the elevator drive assembly 100 to effect elevator drive and a second type of rail 60 for use in conjunction with the guide mechanism 400. The first type of rail 50 is disposed in a neutral position and a second type of rail 60 is disposed on each side of the first type of rail 50. The elevator car frame is connected with the second type rails 60 on the two sides through guide shoes to realize guide limit. The lift drive assembly 100 cooperates with the first type of rail 50 to achieve frictional drive while the lift drive assembly 100 is positioned between the two guide rails, i.e., the second type of rail 60, and is connected to the frame riser.

In one embodiment of the application, the elevator guide rail consists of third class rails arranged on both sides; the third rail is used to cooperate with the lifting drive assembly 100 to realize lifting drive, and is also used to cooperate with the guide mechanism 400.

Above two kinds of elevator guide rail designs, the spacing arm of force of multiplicable elevator direction reduces elevator direction stop gear's load, improves elevator operation transverse stability, reduces the structural dimension of track size and hookup location simultaneously, further reduces the well size.
