[0040] The specific implementation of the utility model will be described below in combination with the drawings.

[0041] As shown in Figure 1 , Figure 2 and Figure 3 , the utility model discloses a power top strong drive villa elevator, which comprises a car 80, a support frame 60 is installed in a shaft above the car 80, a main machine power take-up assembly 10 and a rope head clamp assembly 30 are installed on the support frame 60; the main machine power take-up assembly 10 comprises a main machine shaft 12 directly driven by a driving power 13, a steel belt 40 is wound on the main machine shaft 12, the steel belt 40 drawn out from the main machine shaft 12 is wound downward through a guide wheel set 70 on the car 80, and the end of the steel belt 40 wound out from the guide wheel set 70 extends upward and is clamped to the rope head clamp assembly 30.

[0042] In the embodiment, the power is arranged on the top support frame 60 in combination with the strong drive power structure, so that the overall structure of the elevator is effectively simplified, and the space occupation is reduced.

[0043] In the embodiment, the driving power 13 in the main machine power take-up assembly 10 drives the main machine shaft 12 to rotate, so that the steel belt 40 is driven to perform the take-up and release action on the main machine shaft 12, and the take-up and release of the steel belt 40 realize the lifting drive of the car 80 below.

[0044] In the case of the host power winding assembly 10 top, the guide pulley group 70 can be arranged on the top surface or the bottom surface of the car 80, which can realize the structural arrangement, and the winding of the steel belt 40 can realize the lifting of the car 80.

[0045] In Figure 1 In the first embodiment shown in the embodiment, the guide pulley group 70 is installed on the outer top surface of the car 80, and the guide pulley group 70 includes two groups of guide pulleys which are spaced along the winding direction of the steel belt 40 and are arranged axially in parallel. The steel belt 40 drawn out from the host shaft 12 is downwardly drawn out, reversely changed to horizontal above the top of the car 80 and sequentially wound around the two groups of guide pulleys, and the steel belt 40 constitutes a suspension lifting structure for the top of the car 80. The overall structure is simplified, and the layout is reasonable and compact.

[0046] In Figure 2 And Figure 3 In the second embodiment shown in the embodiment, the guide pulley group 70 is installed on the bottom surface of the car 80, and the guide pulley group 70 includes two groups of guide pulleys which are spaced along the winding direction of the steel belt 40 and are arranged axially in parallel. The guide pulley group 70 also includes a guide wheel 90 installed on the support frame 60 on the outgoing side of the host shaft 12. The steel belt 40 wound around the guide wheel 90 is downwardly drawn out, reversely changed to horizontal below the bottom of the car 80 and sequentially wound around the two groups of guide pulleys, and the steel belt 40 constitutes a suspension lifting structure for the bottom of the car 80.

[0047] In the embodiment, when the guide pulley group 70 is arranged on the bottom of the car 80, the steel belt 40 drawn out from the host power winding assembly 10 needs to pass through the lateral shaft of the car 80 from above, so the guide wheel 90 is arranged in the outgoing direction of the steel belt 40 from the host shaft 12, thereby effectively ensuring the constant outgoing position of the steel belt 40 downwardly, avoiding the change of the outgoing position of the steel belt 40 caused by winding and causing safety problems, and helping to ensure the utilization rate of the shaft.

[0048] In the first embodiment and the second embodiment, only the support frame 60 needs to be arranged in the shaft above the car 80, and the necessary components such as the host power winding assembly 10 and the rope clamp assembly 30 are centrally installed and arranged on the support frame 60, so that the overall components are simplified, reasonable and compact.

[0049] As Figure 4 As shown, the host power winding assembly 10 includes an inverted U-shaped rack 11, and the host shaft 12 is rotatably installed between the two side walls of the rack 11, and the host shaft 12 is driven to rotate by the driving power 13. The two wall surfaces of the rack 11 can also be downwardly extended to form a connecting foot 111, which effectively ensures the installation reliability on the support frame 60.

[0050] In the embodiment, one end of the host shaft 12 extends out of the rack 11 and is connected to the driving power 13, and the driving power 13 is a commonly used rotating drive such as a motor. The other end of the host shaft 12 is located on the rack 11, and common components such as brakes and encoders can be installed thereon to ensure the use of the elevator.

[0051] As shown in Figure 6 and Figure 7 , the outer wall surface of the main shaft 12 is concave to form a flat structure 122, and the flat structure 122 is equipped with a pressing block 15, and the end of the steel belt 40 is pressed between the pressing block 15 and the flat structure 122; the pressing block 15 and the flat structure 122 on the main shaft 12 are attached to realize and ensure the compression and fixation of the end of the steel belt 40.

[0052] In this embodiment, the steel belt 40 is used as the transmission medium, and because the thickness of the steel belt 40 is much smaller than the diameter of the steel wire rope under the same load, it has a natural advantage in reducing the diameter of the drum and the wheel set; through the thickness advantage of the steel belt 40, the structure of the flat structure 122 on the main shaft 12 combined with the pressing block 15 is used to reliably and smoothly fix the end of the steel belt 40, and the overall structure is compact, which can also match the winding of the steel belt 40 on the main shaft 12.

[0053] In actual operation, two flat structures 122 can be arranged circumferentially parallel to the main shaft 12, and the two flat structures 122 are respectively equipped with a pressing block 15, and the end of the steel belt 40 is sequentially attached to the two flat structures 122 and is pressed by the corresponding pressing block 15, so that the end of the steel belt 40 is compressed and fixed twice in succession, effectively ensuring the fixation reliability of the end of the steel belt 40.

[0054] The size of the flat structure 122 in the length direction of the main shaft 12 is greater than the width size of the steel belt 40, and the fastener 16 is locked from top to bottom through the pressing block 15 to the flat structure 122, and the fastener 16 is located on both sides of the width direction of the steel belt 40; the locking of the fastener 16 ensures the compression of the pressing block 15 to the steel belt 40, the overall structure is simple, and the end of the steel belt 40 is convenient to disassemble and assemble, so that the steel belt 40 can be quickly replaced and reused when needed.

[0055] In this embodiment, the surface of the pressing block 15 away from the flat structure 122 is located on the same circumferential surface as the circumferential wall surface of the main shaft 12, and the pressing block 15 and the main shaft 12 cooperate to form a split shaft, and the outer circumference is located on the same circumferential surface, which guarantees the effect of the steel belt 40 after winding.

[0056] As shown in Figure 5 , an even number of baffle plates 14 are axially spaced and sleeved on the main shaft 12, the baffle plates 14 are paired, and the paired baffle plates 14 form a limiting space for winding the corresponding steel belt 40; during the winding process of the steel belt 40, the baffle plates 14 on both sides guide and limit the winding of the steel belt 40 to prevent the steel belt 40 from deviating during operation, effectively ensuring the reliable, stable and smooth winding of the steel belt 40, and guaranteeing safety.

[0057] In the embodiment, the baffle 14 is an annular plate structure, and the outer circumferential diameter of the baffle 14 is 1.5-3 times the diameter of the main shaft 12; through the baffle 14 with a relatively large outer diameter, on the one hand, a receiving space for the steel belt 40 is formed to limit the steel belt 40 on both sides, and on the other hand, reliable winding guidance is provided for the steel belt 40 before winding, so that the winding is smooth and effective.

[0058] In the embodiment, the inner edge of the baffle 14 can extend laterally along the circumference to form a flange 141, and the fastening bolt is locked to the main shaft 12 after passing through the flange 141; the flanges 141 on the baffles 14 located on both sides of the same groove 121 are arranged in opposite directions; the installation reliability of the baffle 14 on the main shaft 12 is effectively ensured through the setting of the flange 141; the pressure block 15 can also be pressed on both ends of the inner side through the flange 141, so that the limiting of the end of the steel belt 40 is reliable.

[0059] As shown in Figure 8 In the embodiment, the groove 121 can be formed on the circumferential surface of the main shaft 12 between the edges of the planar structure 122, and the width of the groove 121 is matched with the width of the steel belt 40; a pair of baffles 14 are installed on both sides of the groove 121; the depth of the groove 121 is limited, and in actual operation, the initial winding of the steel belt 40 on the main shaft 12 is positioned by the groove 121, and after the baffle 14 is installed, the winding of the steel belt 40 is limited by the baffle 14.

[0060] In the case that the main machine power winding and unwinding assembly 10 is placed on the support frame 60 and installed together with the rope clamp assembly 30, the rope clamp assembly 30 can be arranged horizontally or vertically according to the actual space conditions, such as the horizontal and vertical space size of the support frame 60.

[0061] In combination with the height size of the main machine power winding and unwinding assembly 10, the horizontal arrangement of the rope clamp assembly 30 can save vertical space. Figure 9 In the embodiment shown in the figure, the rope clamp assembly 30 is arranged horizontally relative to the support frame 60, and the reversing wheel assembly 50 is installed on the support frame 60 on the side where the rope clamp assembly 30 enters the rope; after the steel belt 40 is reversed to be horizontal by the reversing wheel assembly 50, the end of the steel belt 40 is fixed to the rope clamp assembly 30.

[0062] The reversing wheel assembly 50 is installed on the support 51, and the damping member 52 is installed between the support 51 and the support frame 60; the damping member 52 includes steel plates arranged in an upper and lower interval, and damping pads are arranged in the circumferential direction between the steel plates; as shown in Figure 10As shown, long studs 53 are installed through the support 51 and the upper and lower steel plates, and the support frame 60. The middle part of the long stud 53 is a smooth rod part. The two ends of the long stud 53 extending out of the support 51 and the support frame 60 are threaded parts. Locking nuts 54 are installed on the two end threaded parts of the long stud 53.

[0063] In this embodiment, the long stud 53 structure that penetrates up and down makes the damping member 52 not only play a role in damping in the height direction, but also bear the lateral force caused by the transverse arrangement of the rope head. The support 51 and the support frame 60 are pulled by the long stud 53, so as to avoid the safety risk caused by the upper and lower steel plates of the damping member 52 being pulled off due to the lateral force.

[0064] In this embodiment, the middle part of the long stud 53 is set as a smooth rod part, which effectively avoids friction noise between the shaft and the hole. In addition, the locking of the locking nuts 54 at both ends can be position-limited, and the length of the smooth rod part effectively ensures the space between the support 51 and the support frame 60, guarantees the damping effect of the damping member 52, and avoids the locking nuts 54 being locked too much in the full-thread condition, which causes the damping rubber pad to be pressed to death and lose the buffering effect.

[0065] In this embodiment, the damping member 52 includes at least two groups arranged side by side on the support frame 60. At least one group of damping members 52 is installed by the long stud 53 that penetrates up and down, so as to bear the lateral force. The upper and lower steel plates in at least one group of damping members 52 are independently locked and fixed by the short studs 55 respectively with the abutting support 51 and support frame 60. The installation of multiple groups of damping members 52 in parallel effectively guarantees the damping effect and meets the damping requirement.

[0066] In this embodiment, the wheel shaft 56 at the end of the reversing wheel assembly 50 is supported on the support 51. The locking member with an inverted U-shaped structure is downwardly buckled on the wheel shaft 56. The bottom end of the locking member is inserted into the support 51, so as to realize the installation of the reversing wheel assembly 50. A guide limiting groove that is adapted to limit the steel belt 40 can also be formed on the circumferential wall surface of the reversing wheel assembly 50.

[0067] In another embodiment, for example Figure 2 and Figure 3 As shown, the rope clamp assembly 30 is vertically arranged relative to the support frame 60 in combination with the arrangement space on the support frame 60. The steel belt 40 is extended upward after being led out from the guide wheel set 70 of the car 80 and is clamped by the rope clamp assembly 30.

[0068] Of course, for the use case in Figure 2 and Figure 3 , the rope clamp assembly 30 can also be arranged on the bottom surface of the support frame 60 for transverse arrangement according to the actual layout, so as to solve the problem of insufficient horizontal space on the top surface of the support frame 60, and match the reversing wheel assembly 50 in the transverse arrangement.

[0069] In actual operation, the horizontal or vertical arrangement of the rope head clamp assembly 30 can be comprehensively considered according to actual conditions, such as the horizontal space, vertical space, etc. of the hoistway.

[0070] As shown in Figure 11 and Figure 12 , the structure of the rope head clamp assembly 30 is: a supporting rod 32 is penetrated through the clamp seat 20, a rope penetrating block 37 is installed at the end of the supporting rod 32, a through opening 371 is formed in the rope penetrating block 37, a steel band 40 is inserted into the small end and extended out of the large end of the opening 371, and then reversely folded at the large end and extended out of the small end, and the end of the steel band 40 extended out of the small end is installed with a steel band clamp 38; the wedge block 39 is pressed and assembled between the double-layer steel bands 40 in the rope penetrating block 37.

[0071] In actual operation, the steel band 40 is inserted into the small end and extended out of the large end of the rope penetrating block 37, the wedge block 39 is covered by the steel band 40 from the large end and then inserted back into the opening 371 of the rope penetrating block 37, the end of the steel band 40 is extended out of the small end and pulled tight and then installed with the steel band clamp 38, the steel band 40 is pressed by the wedge surface between the wedge block 39 and the opening 371, and the installation of the end of the steel band 40 on the rope head clamp assembly 30 is completed.

[0072] In this embodiment, the steel band clamp 38 can be a structure of opposite buckling and mutual locking with fasteners to prevent the steel band 40 from loosening and retracting into the small end of the opening 371.

[0073] The supporting rod 32 away from the rope penetrating block 37 and located on the other side of the clamp seat 20 is sequentially sleeved with a positioning block 31, a gasket 34, an elastic piece 33, a gasket 34, and is threadedly locked with two locking nuts 35; a bolt 36 is radially inserted on the supporting rod 32 close to the outer side of the locking nut 35; the setting of the elastic piece 33 on the supporting rod 32 makes the rope head clamp assembly 30 clamping the end of the steel band 40 have a moving buffer elasticity; the bolt 36 is used to prevent the locking nut 35 from falling off.

[0074] In this embodiment, the end of the supporting rod 32 is threadedly fitted with the rope penetrating block 37; a through groove is formed in the wedge block 39, a locking pin is horizontally penetrated through the rope penetrating block 37 and the through groove, and the locking pin is used to prevent the wedge block 39 from separating from the rope penetrating block 37.
