Description

Technical Field

[0001] This invention relates to the field of elevator technology, and more specifically to a compact villa elevator. Background Technology

[0002] Elevators, as an important transportation device in modern buildings, are widely used in various types of residential buildings. In villa construction, the demand for installing elevators inside is becoming increasingly common to improve living convenience.

[0003] Chinese patent application CN202423095567.X proposes a steel belt villa elevator. This design uses a steel belt traction machine and guides the steel belt by setting a guide wheel beam and two guide wheels, which reduces the size of the traction wheel and guide wheels to some extent. However, the two guide wheels are arranged in a completely horizontally staggered manner in the front-to-back direction of the shaft, with no vertical projection overlap. This results in an excessively large size of the guide wheel assembly in the front-to-back direction, making it unsuitable for the narrow shaft scenarios of small villas and self-built houses. Secondly, the split guide wheel beam has no rigid connection with the main frame and the car load-bearing beam. In addition, the overall structure of the elevator is not compact enough, has poor adaptability, and is difficult to promote and apply in residential environments with limited space. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, the present invention provides a compact villa elevator.

[0005] The technical solution adopted by this invention to solve its technical problem is: A compact villa elevator includes a hoist, two counterweight guide rails and two car guide rails disposed within the hoist, a main frame connected to the top of the two counterweight guide rails, a load-bearing beam connected to the top of the two car guide rails, a traction machine disposed on the top of the main frame, a counterweight device that slides with the counterweight guide rails, and a car device that slides with the car guide rails; the counterweight device is provided with a counterweight pulley, and the car device is provided with a car top pulley; characterized in that: the bottom of the load-bearing beam is connected to two top frames that are distributed laterally and rigidly connected to the main frame; The two top frames are connected by a front top seat, a first shaft, and a second shaft arranged sequentially from front to back. The output shaft of the traction machine is equipped with a traction pulley. Each traction pulley is matched with a traction module. Each traction module includes a traction steel belt wound on the traction pulley, a first guide wheel installed on the first shaft, and a second guide wheel installed on the second shaft. The projections of the first guide wheel and the second guide wheel in the same traction module in the vertical direction overlap at least partially. One end of the traction steel belt passes through the second guide wheel, the first guide wheel, and the car top pulley in sequence and is fixedly connected to the front top seat. The other end passes through the counterweight pulley and is fixedly connected to the main frame.

[0006] In this invention, the installation height of the first guide wheel and the traction pulley is higher than the installation height of the second guide wheel.

[0007] In this invention, there are two traction pulleys arranged from left to right, each traction pulley corresponds to an independent traction module, the first guide wheels of the two traction modules are mounted on the same first shaft and are arranged at left and right intervals, and the two second guide wheels are mounted on the same second shaft and are arranged at left and right intervals.

[0008] In this invention, the main frame includes a main frame top plate, two main frame side seats respectively disposed on the left and right sides of the bottom of the main frame top plate, and a main frame front seat located between the two main frame side seats. The main frame front seat is welded and fixed to the main frame side seats. The top ends of the main frame front seat and the top ends of the main frame side seats are both welded to the bottom surface of the main frame top plate. Two counterweight guide rails are respectively connected to the inner side walls of the two main frame side seats. The counterweight guide rails and the main frame side seats are connected by a counterweight rail clamping block assembly.

[0009] In this invention, two main unit mounting seats distributed on the left and right are welded on the top surface of the main unit top plate. The base of the traction machine rests on the two main unit mounting seats, and the base of the traction machine is connected and fixed to the main unit mounting seats by main unit fixing bolts.

[0010] In this invention, the top plate of the main unit is provided with a top plate steel belt clearance opening for the traction steel belt to pass through, so that the other end of the traction steel belt passes through the top plate steel belt clearance opening after changing direction via the traction pulley, and then goes around the counterweight pulley and is fixedly connected to the main unit frame.

[0011] In this invention, the front top seat is provided with a front rope end connecting assembly for connecting and fixing one end of the traction steel belt, and the main unit top plate is provided with a rear rope end connecting assembly for connecting and fixing the other end of the traction steel belt.

[0012] In this invention, the front end of the main unit top plate is provided with two symmetrically arranged top frame clearance spaces and a reversing clearance space located between the two top frame clearance spaces. The top frame clearance space and the reversing clearance space are both arranged through the upper and lower ends and the front end of the main unit top plate. The top frame clearance space is used to accommodate the rear end of the top frame, and the reversing clearance space avoids the second guide wheel and the traction steel belt.

[0013] In this invention, the top frame includes a second guide wheel seat, a vertical connecting seat and a horizontal connecting seat. The rear ends of the second guide wheel seats of the two top frames are respectively inserted into the clearance space of the two top frames, and the second guide wheel seats are fixedly connected to the front seat of the main unit. The front end of the second guide wheel seat is provided with a shaft mounting hole, and the left and right ends of the second shaft are respectively inserted into the shaft mounting holes at the front end of the two second guide wheel seats; The lower end of the vertical connecting seat is fixedly connected to the front end of the second guide wheel seat, and the upper end is fixedly connected to the rear end of the horizontal connecting seat.

[0014] In this invention, load-bearing connecting seats are provided at the bottom of both the left and right ends of the load-bearing beam, and the load-bearing connecting seats at the left and right ends are respectively installed on the top of the two car guide rails; the load-bearing connecting seat includes a load-bearing horizontal support plate for pressing against the top of the car guide rail and a load-bearing vertical support plate for resting on the outside of the car guide rail, the bottom of the load-bearing beam is connected to the top of the load-bearing horizontal support plate, and the load-bearing vertical support plate is connected to the car guide rail by a car rail clamping block assembly.

[0015] The beneficial effects of this invention are: 1. The present invention sets the first guide wheel and the second guide wheel of the same traction module to have at least partial overlap in vertical projection, which abandons the conventional design of the two guide wheels being completely staggered front and back with no projection overlap in the prior art. This reduces the length occupied by the guide wheel group in the front and back direction of the shaft and effectively reduces the space requirements of the villa shaft in the front and back direction. 2. At the same time, the top frame clearance space and reversing clearance space set at the front end of the main frame can be used to make the rear end of the top frame, the second guide wheel and the main frame overlap twice in the front and rear directions, making the structure more compact and further reducing the front and rear dimensions of the top structure, making it more suitable for use in environments with small internal space of the derrick. 3. With the embedded installation structure of the electronic safety clamp, there is no need to increase the size of the car frame column for the safety clamp, which effectively reduces the lateral width occupied by the car frame and reduces the dimensional requirements of the hoistway in the left and right directions; 4. This invention optimizes the car guide shoe disassembly and assembly structure, allowing maintenance personnel to directly inspect and replace the lower guide shoes inside the car without entering the hoistway. This solves the maintenance problem of compact hoistways and reduces the safety risks of maintenance operations.

[0016] In summary, this invention achieves a compact elevator structure, improves the adaptability of home villa elevators to narrow shafts and small spaces, and has strong practicality and promotional value. Attached Figure Description

Furthermore, the counterweight rail clamping block assembly 214 includes a top counterweight rail clamping block 400, a top counterweight rail bolt, and a top counterweight rail nut. The top counterweight rail clamping block 400 and the main unit side seat vertical plate 2121 are clamped together on the main body of the counterweight guide rail 2. The screw of the top counterweight rail bolt passes through the top through hole of the top counterweight rail clamping block 400 and the through hole of the main unit side seat vertical plate 2121 and then engages with the top counterweight rail nut, thereby achieving combined installation.

[0027] In this embodiment, two main mounting bases 2111, distributed left and right, are welded to the top surface of the main unit top plate 211. The base of the traction machine 6 rests on the two main mounting bases 2111, and the base of the traction machine 6 is connected and fixed to the main mounting bases 2111 by main unit fixing bolts.

The top frame clearance space 2114 is used to accommodate the rear end of the top frame 7. The reversing clearance space 2115 avoids the second guide wheel 64 and the traction steel belt 62. With this structure, the rear end of the top frame 7, the second guide wheel 64 and the main unit top plate 211 can be partially overlapped in the front-back direction, making the structure more compact and reducing the space occupied in the front-back direction.

[0030] In this embodiment, the top frame 7 includes a second guide wheel seat 701, a vertical connecting seat 702, and a horizontal connecting seat 703.

[0033] In this embodiment, the car device 5 includes a car frame 51 and a car body 52 disposed within the car frame 51. The car frame 51 includes two symmetrically arranged support columns 511, a car chassis 512 fixedly connected to the lower ends of the two support columns 511 at both ends, and a car top beam 513 fixedly connected to the upper ends of the two support columns 511 at both ends. The support columns 511 are provided with guide rail clearance grooves 5111, and the car top beam 513 is provided with two upper car guide shoes 53, which correspond to the upper car guide shoes 53 above the guide rail clearance grooves 5111 of the two support columns 511. The lower end of the inner cavity of the guide rail clearance groove 5111 is provided with a lower car guide shoe 54 corresponding to the upper car guide shoe 53. The left and right ends of the car top beam 513 are provided with column seats 514, and the column seats 514 are provided with column receiving cavities 5141 for accommodating the upper ends of the support columns 511. The car top beam 513 is connected and fixed to the frame column 511 via the column base 514. The upper end of the frame column 511 is inserted into the column receiving cavity 5141 and fixed to the column base 514 by bolt connection.

The guide rail clearance groove 5111 is provided with an electronic safety clamp 55 corresponding to the upper car guide shoe 53. The fixed end of the electronic safety clamp 55 passes through the safety clearance port 5112 into the column receiving cavity 5141 and is rigidly fixed to the column base 514. This makes the electronic safety clamp 55 partially located in the column receiving cavity 5141, reducing the space occupied by the electronic safety clamp 55 in the guide rail clearance groove 5111, so that the size of the frame column 511 does not need to be increased to increase the depth of the guide rail clearance groove 5111. The guide section of the car guide rail 3 extends into the brake groove of the electronic safety clamp 55 to achieve real-time clamping and braking of the guide section of the guide rail by the electronic safety clamp 55.

[0034] In this embodiment, the thickness of the support column 511 in the left-right direction is less than the inner cavity width of the support column receiving cavity 5141 in the same direction. This allows for redundant space between the side of the support column 511 facing the car body 52 and the inner wall of the support column receiving cavity 5141 after they are assembled. This redundant space is used to accommodate the fixing end of the electronic safety clamp 55, thereby reducing the risk of spatial interference of the electronic safety clamp 55 in the guide rail clearance groove 5111. Furthermore, the column base 514 is provided with a plurality of safety clamp connection holes arranged in an array. The safety clamp connection holes penetrate the column base 514 from left to right and are connected to the column receiving cavity 5141. The fixed end of the electronic safety clamp 55 is provided with safety clamp mating holes corresponding to the safety clamp connection holes. The safety clamp fixing bolt is mated in the corresponding safety clamp connection holes and safety clamp mating holes. Preferably, the safety clamp connection hole is an elongated hole extending from front to back in the length direction, and the safety clamp mating hole is a threaded hole for threaded engagement with the safety clamp fixing bolt, thereby facilitating the adjustment of the position of the electronic safety clamp 55 in the guide rail clearance groove 5111.

[0035] In this embodiment, the car top beam 513 is provided with a car top wheel cavity, and a non-rotatable car top wheel axle 515 is fixedly installed on the car top beam 513.

The upper beam connecting plate 516 has two ends located at the top of the car top beam 513. The two upper car guide shoes 53 are respectively installed on the two upper beam connecting plates 516. The upper beam connecting plate 516 and the upper car guide shoes 53 are connected by bolts.

[0037] In this embodiment, the upper end of the support column 511, the upper end of the support column base 514, and one end of the main body of the top beam are installed together by bolt connection, and the lower end of the support column base 514 is fixed together with the support column 511 by bolt connection.

[0038] In this embodiment, the car body 52 includes a car top 521, an upper car bottom 522, a car front wall 523, a car rear wall 524, and two car side walls 525 distributed on the left and right. The car front wall 523 is provided with a car entrance and exit. The left and right ends of the car front wall 523 are fixedly connected to the front ends of the two car side walls 525, respectively. The left and right ends of the car rear wall 524 are fixedly connected to the rear ends of the two car side walls 525, respectively. The car top 521 is connected to the top of the car side walls 525, the car front wall 523, and the car rear wall 524. The upper car bottom 522 is fixedly connected to the bottom of the car side walls 525, the car front wall 523, and the car rear wall 524.

[0039] Furthermore, each of the support columns 511 is correspondingly arranged on the outer side of a car side wall 525. The car side wall 525 has a disassembly / removal opening 5251 corresponding to the position of the lower car guide shoe 54. The support column 511 has an installation port 5113 for inserting or removing the lower car guide shoe 54 into the guide rail clearance groove 5111. The installation port 5113 corresponds to the position of the disassembly / removal opening 5251 and communicates with the inner cavity of the guide rail clearance groove 5111. When it is necessary to disassemble or assemble the lower car guide shoe 54, the operator... The operator only needs to reach the tool through the disassembly opening 5251 inside the car body 52 and tighten or replace the lower car guide shoe 54 through the installation port 5113, which effectively improves maintenance efficiency. The side of the car side wall 525 facing the inside of the car body 52 can also be detachably installed with an inner side cover 526 for closing and covering the disassembly opening 5251. By covering the disassembly opening 5251 with the inner side cover 526, the interior of the car is visually complete and meets the decorative requirements, and foreign objects are also prevented from falling out of the disassembly opening 5251 to the outside of the car body 52.

[0040] In this embodiment, the lower car guide shoe 54 includes a lower guide shoe mounting seat and a wear-resistant liner detachably fixed to the lower guide shoe mounting seat.

The screw end of the first limiting adjustment bolt 86 passes through the first adjustment through holes of the base mating part 821 and the first limiting adjustment seat 85 and is threaded into the first limiting adjustment nut 87. By rotating the first limiting adjustment bolt 86, the position of the first limiting adjustment nut 87 on the first limiting adjustment bolt 86 changes, thereby driving the base mating part 821 to slide along the length direction of the side limiting adjustment groove 831, realizing the adjustment of the front-to-back position of the side limiting component relative to the limiting base 82. Furthermore, for ease of adjustment, the first limiting adjustment nut 87 can be welded to the base mating part 821, so that a wrench is not needed to fix the first limiting adjustment nut 87 during adjustment.

[0058] In this embodiment, the transverse limiting beam 81 is provided with a transverse limiting fitting part 811 for extending into the side limiting adjustment groove 831.

The screw end of the second limiting adjusting bolt 89 passes through the second adjusting through holes of the horizontal limiting fitting part 811 and the second limiting adjusting seat 88 and is threaded into the second limiting adjusting nut 810. By rotating the second limiting adjusting bolt 89, the front-to-back mating position between the second limiting adjusting bolt 89 and the second limiting adjusting nut 810 changes, thereby driving the horizontal limiting fitting part 811 to translate along the front-to-back direction of the side limiting adjusting groove 831, realizing the front-to-back position adjustment of the horizontal limiting beam 81 relative to the side limiting assembly. In addition, for convenient adjustment, the second limiting adjusting nut 810 can be welded and fixed to the horizontal limiting fitting part 811, so that the second limiting adjusting nut 810 does not need to be fixed with a wrench during adjustment.

[0059] Furthermore, the side limiting beam 83 and the base mating part 821, as well as the side limiting beam 83 and the transverse limiting mating part 811, are all fixedly connected by a limiting bolt assembly to facilitate position locking after adjustment.

[0060] Furthermore, each of the side limiting beams 83 is provided with two side beam hole structures, which correspond to the base mating part 821 and the horizontal limiting mating part 811 respectively, thereby realizing their installation and positioning; each side beam adjustment hole structure includes two sets of side beam adjustment holes respectively provided on the upper and lower sides of the side limiting beam 83, each set of side beam adjustment holes includes at least two side beam adjustment elongated oval holes 832 arranged along the length direction of the side limiting beam 83, the length of the side beam adjustment elongated oval holes 832 extends from left to right, and the side beam adjustment elongated oval holes 832 are all connected to the side limiting adjustment groove 831. Both the base mating part 821 and the horizontal limiting mating part 811 are provided with adjusting mounting elongated holes 800 corresponding one-to-one with the side beam adjusting elongated holes 832. The length direction of the adjusting mounting elongated holes 800 is parallel to the front-rear direction. The corresponding side beam adjusting elongated holes 832 and adjusting mounting elongated holes 800 are connected and locked by a limiting bolt assembly. The limiting bolt assembly includes a limiting bolt and a limiting nut. The thread of the limiting bolt passes through the side beam adjusting elongated holes 832 and the corresponding adjusting mounting elongated holes 800 in sequence, and then engages with the limiting nut to lock it in place, thereby fixing the position of the base mating part 821 and the horizontal limiting mating part 811. The limiting bolt assembly is not shown in the attached drawings.

[0061] Furthermore, the outer frame clamping plate 84 is located on the top surface of the side limiting beam 83. The outer frame clamping plate 84 is used to contact the left or right side of the derrick 1 to achieve limiting. The outer frame clamping plate 84 is provided with at least two clamping plate elongated holes 841 arranged from front to back. The length direction of the clamping plate elongated holes 841 is parallel to the length direction of the side beam adjusting elongated holes 832, so that the outer frame clamping plate 84 can be adjusted left and right. Each clamping plate elongated hole 841 corresponds one-to-one with the side beam adjusting elongated holes 832 on the top surface of the side limiting beam 83. The outer frame clamping plate 84 is passed through and locked by the limiting bolt assembly located on the upper part of the side limiting beam 83. That is, the threaded part of the limiting bolt located on the upper part of the side limiting beam 83 also passes through the clamping plate elongated hole 841, so that after the limiting nut is locked, the position of the outer frame clamping plate 84 is locked at the same time, thereby reducing the number of parts.
