DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0027] Please refer to Figure 1 to Figure 3 The utility model provides a construction elevator, including a lifting car 7, a wall frame 2 installed on a wall 1, a rack 11 and a linear guide 8 installed on the wall frame 2, and a lifting drive motor 12 installed on the lifting car 7, a lifting drive gear 13 of the lifting drive motor 12 is meshed with the rack 11, and the lifting car 7 is matched with the linear guide 8 through rollers.

[0028] A first protective shell 3 is provided on the wall-mounted frame 2, and the non-working surface of the rack 11 is wrapped in the first protective shell 3; the lifting car 7 is provided with a dust removal and lubrication system and a second protective shell 4, and the part of the lifting drive gear 13 away from the rack 11 is wrapped in the second protective shell 4, and the dust removal and lubrication front end component of the dust removal and lubrication system contacts the lifting drive gear 13.

[0029] In the present invention, the first protective housing 3 is mounted on the wall frame 2, covering the non-working surface of the rack 11 to prevent erosion by dust, moisture and other pollutants. The second protective housing 4 is mounted on the lift car 7 to protect the exposed part of the lift drive gear 13 and reduce the impact of environmental factors on its performance.

[0030] The dust removal and lubrication system is composed of multiple components, including but not limited to a dust removal device, a lubricating oil supply system, and a lubricating oil distribution structure. The dust removal and lubrication system contacts the lifting drive gear 13 through the front end component, automatically removes dust and impurities attached to the gear, and provides lubricating oil to reduce friction and wear.

[0031] During the lifting process, the dust removal and lubrication system operates continuously to ensure that the lifting drive gear 13 is properly cleaned and lubricated at all times, thereby improving the operating efficiency and safety of the lift.

[0032] When installing the protective housing and dust removal lubrication system, it is necessary to ensure that they are precisely matched with the rack 11 and the lifting drive gear 13 to avoid interference or excessive clearance during operation. Although the dust removal lubrication system reduces the need for manual maintenance, it is still necessary to regularly check the working status of the system, including the replenishment of lubricants and the cleaning of the dust removal device. Under different environmental conditions, such as extreme temperature or humidity, the performance of the protective housing and lubrication system needs to be evaluated to ensure that they can work properly under various conditions. Before the construction hoist is put into use, a comprehensive safety inspection of the protective housing and dust removal lubrication system should be carried out to ensure that there are no safety hazards.

[0033] In an optional embodiment of the utility model, the lifting car 7 is also provided with a gear-type fall arrester 10, the fall arrester gear 14 of the gear-type fall arrester 10 is meshed with the rack 11, and the part away from the rack 11 is wrapped in the second protective shell 4, and the dust removal and lubrication front end component of the dust removal and lubrication system is also in contact with the fall arrester gear 14.

[0034] By arranging the gear type fall arrester 10 on the lift car 7, when the lift drive system fails, the fall arrester gear 14 can immediately mesh with the rack 11 to prevent the car from falling, which significantly improves the safety of the construction hoist. The gear type fall arrester 10 supplements the lift drive system and provides a second layer of safety protection. Even if the lift drive gear 13 fails, the fall arrester can ensure the safety of the car.

[0035] The part of the fall arrester gear 14 that is away from the rack 11 is wrapped by the second protective shell 4, which not only protects the fall arrester gear 14 from erosion by environmental factors, but also shares the same protective measures with the lifting drive gear 13, simplifying the design and maintenance. Since the dust removal and lubrication front end components of the dust removal and lubrication system are in contact with the lifting drive gear 13 and the fall arrester gear 14 at the same time, simultaneous maintenance of the two key components is achieved, thereby improving maintenance efficiency. It can be seen that the introduction of the toothed fall arrester 10 not only improves the safety performance of the construction elevator, but also improves the reliability and maintenance efficiency of the system by integrating protection and maintenance measures, and also contributes to the technological innovation and industry development of the construction elevator.

[0036] In an optional embodiment of the present invention, Figure 4 As shown, the dust removal and lubrication system includes an oil supply box 6 installed on the lifting car 7, an oil suction lubrication dust removal brush 15 installed in the second protective shell 4, and an oil supply intermediate part 5 for transporting the lubricating oil in the oil supply box 6 to the oil suction lubrication dust removal brush 15; the oil suction lubrication dust removal brush 15 is the dust removal and lubrication front end component of the dust removal and lubrication system.

[0037] Through the coordinated work of the oil supply box 6, the oil-absorbing lubricating dust removal brush 15 and the oil supply middleware 5, the system can continuously supply lubricating oil to the lifting drive gear 13 and the anti-fall gear 14, ensuring their smooth operation and reducing wear during the lifting process.

[0038] The oil-absorbing lubricating dust-removing brush 15 not only provides lubrication, but also has a dust-removing function, which can remove dust and impurities attached to the gears to prevent these impurities from further damaging the gears. Since the oil supply tank 6 is installed in the lift car 7, maintenance personnel can easily check and replenish lubricating oil, simplifying the maintenance process.

[0039] In an optional embodiment of the utility model, the oil supply middleware 5 is an oil supply pipeline, and an oil supply pump is installed in the oil supply box 6 to slowly supply oil to the oil suction lubrication dust removal brush 15 through the oil supply pipeline, thereby improving lubrication efficiency and reducing oil waste; enhancing system reliability and reducing the risk of equipment failure due to insufficient oil.

[0040] In an optional embodiment of the utility model, the oil supply middle piece 5 is an oil-absorbing material strip, which simplifies the design of the oil supply system and improves the transmission efficiency and uniformity of the lubricating oil. The oil-absorbing material strip can continuously and stably provide oil to the lubricating dust removal brush, ensuring that the gears are continuously lubricated and cleaned, thereby extending the service life of the equipment; at the same time, the material strip is easy to maintain and replace, reducing maintenance costs.

[0041] In an optional embodiment of the utility model, an oil receiving tank 9 is provided below the rack 11, and the lower ends of the first protective housing 3 and the rack 11 extend directly into the oil tank 9. By providing the oil receiving tank 9 to collect the oil dripping from the rack 11 and the first protective housing 3, the lubricating oil is effectively recycled, waste is reduced, oil pollution at the construction site is reduced, and environmental friendliness is improved; the waste oil treatment process is simplified and maintenance costs are reduced.

[0042] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
