Description

Technical Field

[0001] The utility model relates to a novel villa ladder structure, belonging to the field of elevator equipment. Background Art

[0002] Villa elevator is a small elevator system designed for villas or low-rise residences. Different from traditional large elevators, villa elevators usually have smaller size and load capacity to adapt to the space limitations and residents' needs in villas. Villa elevators usually consist of electric drive devices, cars, car doors and safety systems. Its design takes into account safety, comfort and convenience to meet the vertical transportation needs of family members. It should be noted that villa elevators need to comply with relevant regulations and standards when installed and used, and need to be designed, installed and maintained by professional elevator companies.

[0003] In the prior art, the common villa elevator is a right-angle door villa elevator. Conventional right-angle door villa elevators basically have a side-mounted counterweight or a rear-mounted counterweight, and a traction ratio of 2:1 bottom-supporting structure. This type of elevator structure has limitations on the requirements for the shaft size, and the relative distance between the internal counterweight and the car is large, resulting in a large amount of waste in the internal space of the elevator shaft, thereby reducing the selectivity of the elevator structure and reducing the utilization efficiency of the elevator shaft.

[0004] In summary, the utility model therefore provides a novel villa ladder structure to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a novel villa elevator structure to solve the problem that the elevator structure proposed in the above background technology causes a large amount of waste of the internal space of the elevator shaft.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a new type of villa ladder structure, including two guide rail brackets and a frame system, the two guide rail brackets are respectively fixedly connected to the two diagonals of the elevator shaft, a car is slidably connected between the opposite sides of the two guide rail brackets, a counterweight is fixedly connected to the bottom of one side of the car and one side located on the inner wall of the elevator shaft, a car frame is fixedly connected to the bottom, front and back of the car by bolts, a suspension bridge upper beam is fixedly connected to the top of the car frame and located above the car, the frame system is fixedly connected to the top corner of the elevator shaft, the bottom of the frame system is fixedly connected to a main machine, and the output end of the main machine is connected to a steel belt body for transmission.

[0007] Furthermore, the rack system includes a rack body, the rack body is fixedly connected to the top corner of the elevator shaft, the main machine is fixedly connected to the bottom of the rack body, both sides of the top of the rack body are fixedly connected to guide wheels, and one side of the top of the rack body is fixedly connected to a mounting rail.

[0008] Furthermore, the steel belt body is transmission-connected between the two guide wheels and the output end of the main machine, and the inclination angle between the car and the vertical direction of the installation track is less than 15°.

[0009] Furthermore, both ends of the steel belt body extend to the top of the counterweight and the upper beam of the suspension bridge respectively.

[0010] Furthermore, the portion of the steel belt main body located above the car is the car side steel belt, and the portion of the steel belt main body located above the counterweight is the counterweight side steel belt.

[0011] Furthermore, one end of the steel belt body is fixedly connected to the top of the counterweight machine, and the other end of the steel belt body is fixedly connected to the top of the upper beam of the suspension bridge.

[0012] Furthermore, the frame system and the upper beam of the suspension bridge form a top-hung right-angle door structure with a traction ratio of 1:1.

[0013] Beneficial effects of the utility model:

[0014] By installing the frame system as a whole at the top corner of the elevator shaft, the frame system and the upper beam of the suspension bridge form a top-hanging right-angle door structure with a traction ratio of 1:1, thereby eliminating the use of the counterweight and the guide wheels above the car frame, and compressing the relative distance between the counterweight and the car, thereby transferring the saved space into the effective utilization space of the car, increasing the optionality of the elevator structure, compressing the elevator's requirements for the shaft size, and improving the utilization efficiency of the shaft.

[0015] The main engine is suspended upside down through the guide wheels directly between the counterweight frame and the car frame. The frame body and the upper beam of the suspension bridge are fixed with pressed guide rails. The guide rail brackets are arranged at the corners of the wall to reduce the effective space of the hoistway occupied by the fixed installation of the guide rail brackets. The elevator structure is easy to install and maintain later, with a simple structure, safety and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-3 The two ends of the steel belt body 2 extend to the top of the counterweight machine 1 and the suspension bridge upper beam 5 respectively. The counterweight machine 1 is a heavy-duty engineering machinery equipment used in construction sites. It has a strong carrying capacity and can complete transportation, loading and other tasks.
