Description

Technical Field

[0001] The invention relates to the technical field of lifting elevators, in particular to a strong-drive villa elevator with a bottom-mounted power side. Background Art

[0002] An elevator is a vertical lift equipped with a box-shaped car, used to carry people or goods in multi-story buildings. As a means of vertical transportation, elevators have become an important and indispensable equipment in construction sites. In order to meet the needs of some users, villa elevators have developed rapidly and the demand is also increasing.

[0003] Since the hoistway of villa elevators is generally small, the requirements for hoistway space utilization are getting higher and higher. In actual applications, we often encounter hoistways with relatively small top floor height, bottom pit depth, and hoistway length and width, which poses a challenge to elevator installation.

[0004] The mainstream elevator type with high market acceptance is the traction elevator. The traction elevator needs to be balanced with the counterweight of the car to achieve lifting and lowering. The structure is relatively complex and a machine room is also required. It occupies a large space and is not conducive to use in villa scenarios with limited shaft space. For scenarios with limited top floor height, it may even be necessary to change the overall structure and shape of the villa, increasing construction costs and affecting the aesthetics of the villa building. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a rationally structured strong-drive villa elevator with a bottom-mounted power side, thereby effectively simplifying the overall structure of the elevator system and reducing space occupancy. It is particularly suitable for villa scenarios with limited shaft space and limited top floor height, greatly improving the utilization rate of the shaft space.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A strong-drive villa elevator with a bottom-mounted power side comprises a car, a support frame is installed in a hoistway above the car, a guide wheel group and a rope clamp assembly are installed on the support frame; it also comprises a main engine power retracting assembly located below the car side, the main engine power retracting assembly comprises a main engine shaft directly driven by a driving power, a steel belt is wound on the main engine shaft, the steel belt led out from the main engine shaft passes through the guide wheel group upwards and then passes through the guide wheel group on the car, and the end of the steel belt wound from the guide wheel group is clamped upwards to the rope clamp assembly.

[0008] As a further improvement of the above technical solution:

[0009] The guide wheel group is installed on the outer top surface of the car. The guide wheel group includes two groups of guide wheels that are spaced apart and axially parallel along the winding direction of the steel belt. The steel belt that passes around the guide wheel group is led downward, changes to be horizontal above the top of the car and passes around the two groups of guide wheels in sequence. The steel belt constitutes a suspension and lifting structure for the top of the car.

[0010] The guide wheel group includes a guide wheel 1 installed on the support frame, and the guide wheel 1 is installed on the side of the support frame close to the main engine power retracting and releasing assembly; the guide wheel 1 and the rope end clamp assembly are installed on the support frame in parallel, and the steel belt that is fixed to the rope end clamp assembly after passing through the guide wheel 1 and the guide wheel group forms a U-shaped structure.

[0011] The guide wheel group is installed on the bottom surface of the car, and the guide wheel group includes two groups of guide wheels that are spaced apart and axially parallel along the winding direction of the steel belt. The steel belt that passes around the guide wheel group is led downward, changes to be horizontal below the bottom of the car and passes around the two groups of guide wheels in turn, and the steel belt forms a suspension and lifting structure for the bottom of the car.

[0012] The guide wheel group includes a guide wheel 1 and a guide wheel 2 which are axially parallelly installed on the support frame. The rope end clamp assembly is installed below the guide wheel group. The steel belt horizontally passes through the guide wheel 1 and the guide wheel 2, then changes direction to pass around the guide wheel group downward, and then changes direction to be fixed upward to the rope end clamp assembly.

[0013] The main engine power retractable assembly is also provided with a guide wheel, the axial direction of which is parallel to the axial direction of the main engine shaft. The guide wheel is located obliquely above the main engine shaft, and the steel belt wound around the main engine shaft is led out upward after passing through the guide wheel.

[0014] The main engine power retracting and releasing assembly includes a frame with an inverted U-shaped structure, a main engine shaft is rotatably installed between the two side walls of the frame, the main engine shaft is driven to rotate by the end driving power, a guide wheel seat is installed on the top surface of the frame, and a guide wheel is rotatably installed on the guide wheel seat; the guide wheel is concave inwardly along the circumferential direction to form an annular groove, and the width of the annular groove matches the width of a single steel belt.

[0015] The outer wall surface of the main shaft is concave to form a plane structure, a pressure block is installed at the plane structure, and the end of the steel belt is pressed between the pressure block and the plane structure; an even number of baffles are axially spaced on the main shaft, and the baffles are paired, and the pairs of baffles form a limiting space for winding the corresponding steel belt.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention effectively simplifies the overall structure of the elevator system and reduces space occupancy by arranging the power at the side bottom and adopting a strong driving force structure. It is particularly suitable for villas with limited hoistway space and limited top floor height, greatly improving the utilization rate of the hoistway space.

[0020] The present invention also includes the following advantages:

[0021] By setting a guide wheel on the main engine power take-up and release assembly, the steel belt is wound and led out through the guide wheel to ensure a constant rope outlet point of the steel belt, thereby eliminating the need to lay out the guide pulley in the well, helping to ensure the well utilization rate; and, according to actual installation requirements, the guide wheel can be adjusted to the left or right installation relative to the main engine power take-up and release assembly through the guide wheel seat, which is convenient to use;

[0022] During the steel strip winding process, the baffles on both sides form the guide and limit of the steel strip winding to prevent the steel strip from deviating during operation, effectively ensuring the reliable, stable and smooth winding of the steel strip and ensuring safety;

[0023] Through the lateral setting of the rope end clamp assembly combined with the reversing wheel assembly, the reversing wheel assembly converts the steel belt end from vertical to horizontal, thereby realizing the lateral arrangement of the steel belt rope head structure.

[0042] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, a strong-drive villa elevator with a bottom-mounted power side in this embodiment includes a car 90, a support frame 70 is installed in the hoistway above the car 90, and a guide wheel group and a rope end clamp assembly 50 are installed on the support frame 70; it also includes a main engine power retracting assembly 10 located at the lower side of the car 90, and the main engine power retracting assembly 10 includes a main engine shaft 12 directly driven by a driving power 11, and a steel belt 30 is wound on the main engine shaft 12. The steel belt 30 led out from the main engine shaft 12 passes around the guide wheel group upward and then passes through the guide wheel group 80 on the car 90, and the end of the steel belt 30 wound from the guide wheel group 80 is clamped upward to the rope end clamp assembly 50.

[0044] In this embodiment, by arranging the power at the side bottom and adopting a strong driving force structure, the overall structure of the elevator system is effectively simplified and the space occupancy is reduced.

[0045] exist Figure 1 In the first embodiment shown, the guide wheel group 80 is installed on the outer top surface of the car 90. The guide wheel group 80 includes two groups of guide wheels that are spaced apart and axially parallel along the winding direction of the steel belt 30. The steel belt 30 that passes around the guide wheel group is led downward, changes direction to be horizontal above the top of the car 90 and passes around the two groups of guide wheels in turn. The steel belt 30 constitutes a suspension and lifting structure for the top of the car 90.

[0046] The guide wheel group includes a guide wheel 40 installed on the support frame 70, and the guide wheel 40 is installed on the side of the support frame 70 close to the main engine power retracting assembly 10; the guide wheel 40 and the rope end clamp assembly 50 are installed in parallel on the support frame 70, and the steel belt 30 that is fixed to the rope end clamp assembly 50 after passing through the guide wheel 40 and the guide wheel group 80 forms a U-shaped structure.

[0047] exist Figure 2 and Figure 3 In the second embodiment shown, the guide wheel group 80 is installed on the bottom surface of the car 90. The guide wheel group 80 includes two groups of guide wheels that are spaced apart and axially parallel along the winding direction of the steel belt 30. The steel belt 30 that passes around the guide wheel group is led downward, changes to a horizontal direction below the bottom of the car 90 and passes around the two groups of guide wheels in turn. The steel belt 30 constitutes a suspension and lifting structure for the bottom of the car 90.

[0048] The guide wheel group includes a guide wheel 1 40 and a guide wheel 2 41 which are axially parallelly installed on the support frame 70. The rope end clamp assembly 50 is installed below the guide wheel group. The steel belt 30 horizontally passes through the guide wheel 1 40 and the guide wheel 2 41, then changes direction to pass downward around the guide wheel group 80, and then changes direction to be upwardly fixed to the rope end clamp assembly 50.

[0049] In the first and second embodiments, when the power side is placed at the bottom, two different situations are proposed, in which the guide wheel group 80 for lifting the car 90 is located at the top and bottom of the car 90 respectively; and the layout of the corresponding guide wheel group in different situations.

[0050] In the first and second embodiments, except for the power mechanism placed at the bottom of the side, it is only necessary to arrange a support frame 70 in the shaft above the car 90, and the necessary components such as the guide wheel group and the rope head clamp assembly 50 are centrally installed on the support frame 70, so that the overall components are simplified, reasonable and compact.

[0051] like Figure 4 As shown, a guide wheel 20 is also installed on the main engine power retracting assembly 10. The axial direction of the guide wheel 20 is parallel to the axial direction of the main engine shaft 12. The guide wheel 20 is located obliquely above the main engine shaft 12. The steel belt 30 wrapped around the main engine shaft 12 is led out upward after passing through the guide wheel 20.

[0052] In this embodiment, a guide wheel 20 is provided on the main engine power retracting and releasing assembly 10, and the steel belt 30 is wound and led out through the guide wheel 20 to ensure a constant rope-out point of the steel belt 30, thereby eliminating the need for laying a guide pulley in the hoistway and helping to ensure the utilization rate of the hoistway.

[0053] The main engine power retractable assembly 10 includes a frame 13 with an inverted U-shaped structure, and a main engine shaft 12 is rotatably installed between the two side walls of the frame 13. The main engine shaft 12 is driven to rotate by the end driving power 11. A guide wheel seat 21 is installed on the top surface of the frame 13, and a guide wheel 20 is rotatably installed on the guide wheel seat 21.

[0054] In this embodiment, Figure 5 As shown, the guide wheel seat 21 includes a base plate 211 installed on the top surface of the frame 13, and support plates 212 are symmetrically installed on the base plate 211 at intervals, and the ends of the support plates 212 are rotatably installed together to install the guide wheel 20; the support plate 212 can be installed offset in the left or right direction relative to the base plate 211, so that the guide wheel 20 after installation is located at an oblique upper position to the left or right of the driving power 11.

[0055] During installation, the guide wheel 20 can be adjusted to the left or right position relative to the main engine power retractable assembly 10 through the guide wheel seat 21 according to actual installation requirements, which is convenient to use.

[0056] like Figure 5 As shown, an annular groove is formed on the guide wheel 20 along the circumferential direction. The width of the annular groove matches the width of a single steel belt 30. The steel belt 30 is drawn out by fitting to the wall of the annular groove. The annular groove limits the lead-out position of the steel belt 30 on the guide wheel 20, thereby effectively ensuring a constant rope-out point of the steel belt 30 after it is drawn out through the guide wheel 20 through the annular groove, thereby ensuring the stability and smoothness of the steel belt 30 during operation.

[0057] like Figure 6 As shown, an even number of baffles 14 are axially spaced apart on the main shaft 12, and the baffles 14 are paired, and the paired baffles 14 form a limiting space for winding the corresponding steel belt 30; during the winding process of the steel belt 30, the baffles 14 on both sides form a guide and limit for the steel belt 30 during winding, preventing the steel belt 30 from deviating during operation, effectively ensuring the reliable, stable and smooth winding of the steel belt 30, and ensuring safety.

[0058] In this embodiment, the baffle 14 is an annular sheet structure, and the diameter of the outer circumference of the baffle 14 is 1.5-3 times the diameter of the main shaft 12 at the mounting location; the baffle 14 with a relatively large outer diameter, on the one hand, constitutes a accommodating space for the wound steel strip 30, and limits the wound steel strip 30 on both sides; on the other hand, it can also provide a reliable winding guide for the steel strip 30 before winding, thereby ensuring smooth and effective winding.

[0059] like Figure 7 , Figure 8 and Fig. 9 As shown, the outer wall surface of the main shaft 12 is concave to form a plane structure 122, and a pressure block 15 is installed at the plane structure 122. The end of the steel belt 30 is pressed between the pressure block 15 and the plane structure 122; the pressing and fixing of the end of the steel belt 30 is achieved and guaranteed by the fit between the pressure block 15 and the plane structure 122 on the main shaft 12.

[0060] In this embodiment, a steel belt 30 is used as a transmission medium. Since the thickness of the steel belt 30 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 group. By taking advantage of the thickness of the steel belt 30, the planar structure 122 on the main shaft 12 is combined with the structure of the pressure block 15 to reliably and smoothly fix the end of the steel belt 30. The overall structure is compact and can also match and satisfy the winding of the steel belt 30 on the main shaft 12.

[0061] In actual operation, two planar structures 122 can be arranged in parallel along the circumference of the main shaft 12, and the two planar structures 122 are respectively equipped with pressure blocks 15. The ends of the steel belt 30 are successively attached to the two planar structures 122 and then pressed by the corresponding pressure blocks 15, so that the ends of the steel belt 30 are clamped and fixed twice in succession, effectively ensuring the reliability of the fixation of the ends of the steel belt 30.

[0062] The size of the plane structure 122 in the length direction of the main shaft 12 is larger than the width of the steel belt 30. Fasteners 16 are locked from top to bottom through the pressure block 15 toward the plane structure 122. The fasteners 16 are located on both sides of the width direction of the steel belt 30. The fasteners 16 are locked to ensure that the pressure block 15 presses the steel belt 30. The overall structure is simple, and the ends of the steel belt 30 are easy to disassemble and assemble. The steel belt 30 can be quickly replaced when needed, and the steel belt 30 can be reused.

[0063] In this embodiment, the inner edge of the baffle 14 can extend laterally along the circumferential direction to form a flange 141, and the fastening bolts pass through the flange 141 and are locked to the main shaft 12; the flanges 141 on the baffles 14 on both sides of the same groove 121 are arranged back to back; the arrangement of the flange 141 effectively ensures the installation reliability of the baffle 14 on the main shaft 12; the two ends of the pressure block 15 can also be pressed on the inside through the flange 141 to ensure reliable limiting of the end of the steel belt 30.

[0064] In this embodiment, the surface of the pressure block 15 that is away from the plane structure 122 is located on the same circumferential surface as the circumferential wall of the main shaft 12. The pressure block 15 and the main shaft 12 cooperate to form a split shaft, and their outer circumferences are located on the same circumferential surface, thereby ensuring the effect of the steel belt 30 after winding.

[0065] In this embodiment, a groove 121 can be opened 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 adapted to the width of the steel belt 30 ; two pairs of baffles 14 are installed at the edges of both sides of the groove 121 .

[0066] The depth of the groove 121 is limited. In actual operation, the groove 121 is used to position the initial winding of the steel belt 30 on the main shaft 12. After the baffle 14 is installed, the baffle 14 limits the winding of the steel belt 30.

[0067] One end of the main shaft 12 extends out of the frame 13 and is connected to the driving power 11, which is a common rotating drive such as a motor; the frame 13 located at the other end of the main shaft 12 can be installed with common components such as brakes and encoders to ensure the use of the elevator; the bottom ends of the two walls of the frame 13 can also extend downward to form connecting feet 131 to facilitate the installation and fixation of the frame 13.

[0068] like Fig.10 As shown, a reversing wheel assembly 60 is also installed on the support frame 70. After the steel belt 30 is reversed to the horizontal by the reversing wheel assembly 60, the end of the steel belt 30 is fixed to the rope end clamp assembly 50; the rope end clamp assembly 50 is arranged horizontally on the support frame 70.

[0069] In this embodiment, through the lateral setting of the rope end clamp assembly 50, combined with the reversing wheel assembly 60, the reversing wheel assembly 60 converts the end of the steel belt 30 from vertical to horizontal, thereby realizing the lateral arrangement of the steel belt rope end structure. The layout is reasonable and compact, and the plane space of the shaft is cleverly utilized to effectively reduce the height occupancy, especially reducing the requirements for the top floor height.

[0070] In this embodiment, whether the guide wheel group 80 is arranged at the top of the car 90 in the first embodiment or the guide wheel group 80 is arranged at the bottom of the car 90 in the second embodiment, Figure 1 and Figure 3 As shown, the rope end clamp assembly 50 can be arranged horizontally in combination with the reversing wheel assembly 60 to effectively reduce the height of the used space.

[0071] like Fig.11 As shown, the reversing wheel assembly 60 is installed on the support 62, and a shock-absorbing member 63 is installed between the support 62 and the support frame 70; the shock-absorbing member 63 includes steel plates arranged at intervals above and below, and shock-absorbing pads indented along the circumferential direction are installed between the steel plates; a long stud 64 is installed through the support 62, the upper and lower steel plates, and the support frame 70 from top to bottom, and the middle part of the long stud 64 is a smooth rod part, and the two ends of the long stud 64 extending upward from the support 62 and downward from the support frame 70 are set as threaded parts, and the threaded parts at both ends of the long stud 64 extending out are locked with tightening nuts 65.

[0072] In this embodiment, by adopting a long stud 64 structure that runs through the upper and lower parts, the shock absorber 63 can not only play a shock-absorbing role in the height direction, but also withstand the lateral force caused by the horizontal arrangement of the rope head. The long stud 64 holds the support 62 and the support frame 70, thereby avoiding the safety risk caused by the upper and lower steel plates in the shock absorber 63 being pulled off due to the lateral force.

[0073] In this embodiment, the middle part of the long stud 64 is set as a smooth rod part, which effectively avoids friction noise between the shaft and the hole. Moreover, the locking position of the tightening nuts 65 at both ends can also be limited. The length of the smooth rod part effectively guarantees the space between the support 62 and the support frame 70, ensures the shock-absorbing effect of the shock-absorbing part 63, and avoids excessive locking of the tightening nuts 65 in the full thread state, which will crush the shock-absorbing rubber pad and lose its buffering effect.

[0074] In this embodiment, the shock-absorbing components 63 include at least two groups arranged in parallel on the support frame 70. At least one group of shock-absorbing components 63 is installed using long studs 64 that penetrate from top to bottom to withstand lateral forces. The upper and lower steel plates in at least one group of shock-absorbing components 63 are independently locked and fixed to the fitting support 62 and the support frame 70 using short studs 66. By installing multiple groups of shock-absorbing components 63 in parallel, the shock-absorbing effect is effectively guaranteed and the shock-absorbing requirements are met.

[0075] In this embodiment, the axle 61 at the end of the reversing wheel assembly 60 is supported on the support 62, and an inverted U-shaped locking component is buckled downward on the axle 61, and the bottom end of the locking component is inserted into the support 62 to achieve the installation of the reversing wheel assembly 60; a guide limit groove that adapts to the limit position of the steel belt 30 can also be opened on the circumferential wall surface of the reversing wheel assembly 60.

[0076] like Fig.12 and Fig.13 As shown, the structure of the rope end clamp assembly 50 is: it includes a support rod 52 that passes through the clamp seat 500, and a rope threading block 57 is installed at the end of the support rod 52. The rope threading block 57 and the reversing wheel assembly 60 are located on the same side of the clamp seat 500; a through opening 571 is opened on the rope threading block 57, and the steel belt 30 horizontally led out from the reversing wheel assembly 60 extends from the small end of the opening 571 and extends out from the large end, and then reversely folded at the large end to extend from the small end, and the end of the steel belt 30 extending out of the small end is installed with a steel belt clamp 58; a wedge block 59 is pressed between the double-layer steel belts 30 located inside the rope threading block 57.

[0077] During actual operation, the steel belt 30 is inserted into the small end of the rope threading block 57 and extended out from the large end. The steel belt 30 wraps the wedge block 59 from the large end and is then stuffed back into the opening 571 of the rope threading block 57. The end of the steel belt 30 is extended from the small end and tightened, and then the steel belt clamp 58 is installed. The wedge surface between the wedge block 59 and the opening 571 is pressed against the steel belt 30 to complete the installation of the end of the steel belt 30 on the rope end clamp assembly 50.

[0078] In this embodiment, the steel band clamps 58 may be in a structure that is interlocked with each other using fasteners to prevent the steel band 30 from loosening and shrinking into the small end of the opening 571.

[0079] A positioning block 51, a gasket 54, an elastic member 53, a gasket 54 are sequentially mounted on the support rod 52 located on the other side of the clamp seat 500, away from the rope threading block 57, and two locking nuts 55 are threadedly locked; a pin 56 is radially inserted on the support rod 52 adjacent to the outer side of the locking nut 55; through the arrangement of the elastic member 53 on the support rod 52, the rope end clamp assembly 50 that clamps the end of the steel belt 30 has buffer elasticity for movement; the pin 56 is used to prevent the locking nut 55 from falling off.

[0080] In this embodiment, the end of the support rod 52 is threadedly assembled with the rope threading block 57; a through groove is opened on the wedge block 59, and a locking pin is installed horizontally through the rope threading block 57 and the through groove to prevent the wedge block 59 from detaching from the rope threading block 57.

[0081] In actual operation, the main engine power retractable assembly 10 is arranged at the lower part of the elevator shaft, and the steel belt 30 wound on the main engine shaft 12 in the driving main engine is led upward through the guide wheel 20, and is passed through the guide wheel group on the upper support frame 70 of the shaft. The steel belt 30 is wound from the top guide wheel group 80 of the car 90 or the bottom guide wheel group 80 of the car 90, and the end of the steel belt 30 is fixed to the rope end clamp assembly 50 arranged horizontally on the support frame 70, so that the car 90 can be raised and lowered by the operation of the driving power 11 through the winding and releasing of the steel belt 30.

[0082] In actual use, the driving main unit can be arranged on the left or right side of the lower part of the elevator shaft according to actual needs, and the direction of the guide wheel 20 can be adjusted by installing the guide wheel seat 21 on the frame 13.

[0083] The present invention effectively simplifies the overall structure of the elevator system and reduces space occupancy. It is particularly suitable for villa scenarios with limited hoistway space and limited top floor height, greatly improving the utilization rate of the hoistway space.

[0084] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0085] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
