Description

Technical Field

[0001] This utility model relates to the field of backpack elevator technology, and in particular to a backpack frame structure with a car top wheel steel belt. Background Technology

[0002] Backpack-style elevators are a classic early villa elevator structure, with relatively low requirements for the top floor and pit. They can meet the installation requirements of most residential elevator shafts, and the counterweight and guide rails are on the same side, making them more aesthetically pleasing for panoramic cars. The backpack frame structure is constructed from high-strength steel welded or bolted together, forming a stable triangular or rectangular structure that bears the weight of the car and its load. The car top wheel assembly is located on top of the elevator car and is typically a grooved wheel made of high-strength alloy steel with a precision-machined surface to reduce wear on the steel belt.

[0003] Existing home elevators typically use a single-sided fixing method, which results in the car guide shoes being stressed on one side after being subjected to force. This causes the guide shoes to wear out quickly and vibrate significantly during operation, resulting in low structural strength and poor riding comfort.

[0004] An existing patent (publication number: CN220245218U) discloses a backpack-type home elevator structure, which includes a traction machine located at the far end of the shaft, a car located in the shaft, and a backpack frame assembly. The backpack frame assembly includes four small vertical beams passing through the far end of the car, with wheel beams connecting adjacent small vertical beams. Car return rope pulleys are provided at the front and rear ends of the wheel beams. A main vertical beam is provided at the rear end of the car. Supports are provided on both sides of the rear end of the car inside the shaft. When the car is driven by the steel belt, the load is balanced, reducing uneven loading and noise during operation, improving the elevator ride comfort and the service life of the elevator equipment, especially meeting the elevator installation requirements of small shafts, low top floors, and shallow pits.

[0005] To address the aforementioned issues, while existing patents have proposed solutions that improve elevator comfort and extend the lifespan of elevator equipment, particularly meeting the installation requirements for elevators with small shafts, low top floors, and shallow pits, their backpack-like mechanical structures suffer from uneven load distribution. Furthermore, the car cannot be made too large, and its small size limits its applicability to elevators with smaller shafts. Summary of the Invention

[0006] The purpose of this utility model is to provide a car top wheel steel belt backpack frame structure, in which the elevator steel belt is wrapped around two car anti-corrosion pulleys, so that the car suspension center is roughly coincident with the car's center of gravity. Without changing its original backpack-style advantages, the mechanical structure is optimized. The steel belt is connected to the counterweight and the car respectively through the traction machine. Two car anti-corrosion pulleys are used on the car, so that the car suspension center is roughly coincident with the car's center of gravity. By adjusting the center of gravity through double wheels, the backpack-style suspension method is optimized, increasing the comfort of elevator operation. Furthermore, it allows for a larger car size when the shaft is limited, making it suitable for backpack-style home elevators of various structures, increasing versatility, and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a car roof wheel steel belt backpack frame structure, including an upper beam frame, a car roof plate fixed on the lower surface of the upper beam frame, a hoisting mechanism for hoisting inside the upper beam frame, a reinforcing mechanism for strengthening at the lower end of the hoisting mechanism, and a buffering mechanism for cushioning on the lower surface of the reinforcing mechanism.

[0008] The hoisting mechanism includes two reinforcing plates, both of which are welded to the inside of the upper beam frame. Each of the two reinforcing plates has a fixing rod at its end. A fixing bearing is fitted on the outer surface of the fixing rod, and a car anti-rope pulley is fixed on the outer surface of the fixing bearing.

[0009] Preferably, two auxiliary uprights are fixed to one side of the upper beam frame by bolts, and two main uprights are fixed to the other side of the upper beam frame by bolts.

[0010] Preferably, a lower beam frame is fixed to the inner side of both the secondary beams and the main beam, and a car bottom frame is installed on the upper surface of the lower beam frame.

[0011] Preferably, the reinforcing mechanism includes a fixing plate, which is integrally fixed to one side of the lower beam frame. Four mounting brackets are symmetrically fixed to the inner wall of the lower beam frame. Elastic pads are fixed to the upper surface of each of the four mounting brackets. A connecting plate that is bolted to the car bottom frame is fixed to the upper surface of each elastic pad.

[0012] Preferably, the buffer mechanism includes two sets of buffer components, each set of which is fixed to the lower surface of the fixed plate, and each set of buffer components has a piston installed inside.

[0013] Preferably, a movable rod that is telescopically connected to the buffer is fixed on the lower surface of the piston, and a movable plate is integrally fixed to the end of the movable rod.

[0014] Preferably, the outer surface of the movable rod is fitted with a buffer spring that abuts against the movable plate, the outer surface of the buffer is connected to a compression member, and the side walls of the main beam and the secondary beam are both equipped with car wall frames.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up car anti-reverse rope pulleys, the elevator steel belt is wrapped around two car anti-reverse rope pulleys, so that the car suspension center is roughly aligned with the car's center of gravity. Without changing its original backpack-style advantages, the mechanical structure is optimized. The steel belt is connected to the counterweight and the car respectively through the traction machine. Two car anti-reverse rope pulleys are used on the car to make the car suspension center roughly aligned with the car's center of gravity. By adjusting the center of gravity with double pulleys, the backpack-style suspension method is optimized, increasing the comfort of elevator operation. Moreover, the car size can be increased when the shaft is limited, making it suitable for backpack-style home elevators of various structures and increasing versatility.

[0017] 2. Through the buffer mechanism, the movable plate contacts the bottom of the elevator shaft. The movable plate will push the movable rod to move, which in turn drives the piston to move inside the buffer component, compressing the nitrogen gas filled inside the buffer component. The movement of the movable plate will push the buffer spring to compress, thus playing a buffering role. The nitrogen gas filled inside the buffer component will enter the compression component after being compressed, thereby absorbing a certain impact force and reducing the injury to people inside the elevator.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A car roof wheel steel belt backpack frame structure includes an upper beam frame 1, a car roof plate 2 fixed on the lower surface of the upper beam frame 1, a hoisting mechanism for hoisting is provided inside the upper beam frame 1, a reinforcing mechanism for strengthening is provided at the lower end of the hoisting mechanism, and a buffering mechanism for cushioning is provided on the lower surface of the reinforcing mechanism.

[0028] The hoisting mechanism includes two reinforcing plates 3, which are welded to the inside of the upper beam frame 1. Each reinforcing plate 3 has a fixing rod 31 at its end. A fixing bearing 32 is fitted onto the outer surface of the fixing rod 31, and a car anti-rope pulley 33 is fixed to the outer surface of the fixing bearing 32. Two auxiliary vertical beams 35 are bolted to one side of the upper beam frame 1, and two main vertical beams 36 are bolted to the other side. A lower beam frame 37 is fixed to the inner sides of both the auxiliary vertical beams 35 and the main vertical beams 36. A car bottom frame 34 is mounted on the upper surface of the lower beam frame 37. The reinforcing mechanism includes a fixing plate 4, which is integrally fixed to one side of the lower beam frame 37. Four mounting brackets 41 are symmetrically fixed to the inner wall of the lower beam frame 37. Elastic pads 42 are fixed to the upper surfaces of the four mounting brackets 41, and connecting plates 43, bolted to the car bottom frame 34, are fixed to the upper surfaces of the elastic pads 42.

[0029] By adopting the above technical solution, before using the car top wheel steel belt backpack frame structure, the backpack frame is first assembled into the elevator shaft. The car top plate 2 installed on the upper beam frame 1, in conjunction with the reinforcing plate 3, enhances the overall strength of the upper beam frame 1. Furthermore, the two car anti-rope pulleys 33 on the reinforcing plate 3 allow the elevator steel belt to pass around them, making the car's center of gravity approximately coincide with the car's center of gravity. This optimizes the mechanical structure without altering the original backpack-style advantages. The steel belt is connected to the counterweight and car via a traction machine. Two car anti-rope pulleys 33 are used on the car to make the car's center of gravity approximately coincide with the car's center of gravity. This double-wheel adjustment of the center of gravity optimizes the backpack-style suspension. This design increases elevator operating comfort and allows for larger car sizes in situations with limited shaft space. It is suitable for various types of backpack-style home elevators, increasing versatility. The fixed bearing 32 on the fixed rod 31 ensures the normal rotation of the two car anti-corrosion pulleys 33. The auxiliary upright beam 35 and main upright beam 36 facilitate the connection and fixation of the car wall frame 6. The car bottom frame 34 on the lower beam frame 37 facilitates subsequent car assembly. The mounting bracket 41 on the fixed plate 4, in conjunction with the elastic pad 42 and connecting plate 43, provides a certain buffering effect, preventing the car bottom frame 34 from colliding with the lower beam frame 37 in the event of a fall.

[0030] Specifically, such as Figures 1-4 As shown, the buffer mechanism includes a buffer component 5, which is provided in two sets. Both sets of buffer components 5 are fixed to the lower surface of the fixed plate 4. A piston 51 is installed inside each set of buffer components 5. A movable rod 52 that is telescopically connected to the buffer component 5 is fixed to the lower surface of the piston 51. A movable plate 53 is integrally fixed to the end of the movable rod 52. A buffer spring 54 that abuts against the movable plate 53 is sleeved on the outer surface of the movable rod 52. A compression component 55 is connected to the outer surface of the buffer component 5. A car wall frame 6 is installed on the side walls of the main beam 36 and the secondary beam 35.

[0031] By adopting the above technical solution, the buffer 5 set at the bottom of the fixed plate 4 makes the movable plate 53 contact the bottom of the elevator shaft. The movable plate 53 will push the movable rod 52 to move, which in turn drives the piston 51 to move inside the buffer 5, compressing the nitrogen gas filled inside the buffer 5. At the same time, the movement of the movable plate 53 will push the buffer spring 54 to be compressed, thus playing a buffering role. After being compressed, the nitrogen gas filled inside the buffer 5 will enter the compression member 55, thereby absorbing a certain impact force, reducing the injury to people inside the elevator, and improving practicality.

[0032] Working principle: The car top plate 2 installed on the upper beam frame 1, in conjunction with the reinforcing plate 3, enhances the overall strength of the upper beam frame 1. Furthermore, the two car anti-cord pulleys 33 on the reinforcing plate 3 guide the elevator steel belt around them, ensuring the car's center of gravity roughly coincides with the car's center of gravity. This optimizes the mechanical structure without altering its original backpack-like advantages. The mounting bracket 41 on the fixing plate 4, in conjunction with the elastic pad 42 and connecting plate 43, provides a certain degree of cushioning, preventing damage to the car bottom frame 34. When the backpack frame collides with the lower beam frame 37 and falls, the buffer 5 at the bottom of the fixed plate 4 causes the movable plate 53 to contact the bottom of the elevator shaft. The movable plate 53 pushes the movable rod 52 to move, which in turn drives the piston 51 to move inside the buffer 5, compressing the nitrogen gas filled inside the buffer 5. At the same time, the movement of the movable plate 53 pushes the buffer spring 54 to be compressed, thus playing a buffering role. The nitrogen gas filled inside the buffer 5 is compressed and enters the compression member 55, thereby absorbing a certain impact force.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
