Description

TECHNICAL FIELD

[0001] The utility model relates to an elevator, in particular to a right-angle door opening elevator with adjustable door opening size. BACKGROUND

[0002] Due to the special requirements of building layout and car door orientation, some elevators need to be designed as right-angle door opening elevators that vertically enter and exit the car from two directions. Based on this requirement, the arrangement structure of the existing right-angle door opening elevator is shown in patent 202210775572.1, which sets the elevator guide rail and car door at 45° staggered, so that the car frame can cover the car in a 45° inclined state, leaving space for the car door on the front and side of the car to realize the right-angle door opening function of the elevator.

[0003] However, the structure has the following defects: on the one hand, the two car doors will cause the front and rear and left and right deviation of the car's center of gravity after installation, and the monolithic inclined car frame can only lift two ends of the car, causing the other two ends of the car to tilt or swing due to weight difference, reducing the stability of the elevator. Due to the limitation of the car door structure, manufacturers cannot increase the car frame to lift and limit the other two ends of the car.

[0004] On the other hand, the inclined car frame and its elevator guide rail will occupy the space of the elevator shaft at both end corners after installation, which makes it impossible to use a relatively wide center-split car door assembly to avoid the car frame and elevator guide rail after installation, and instead requires a relatively wide side-opening car door assembly with relatively high cost as the elevator car door, thereby increasing the production cost of the elevator.

[0005] Therefore, the existing right-angle door opening elevator has the problems of poor stability and high equipment cost. UTILITY MODEL CONTENTS

[0006] The utility model aims to provide a right-angle door opening elevator with adjustable door opening size. It has the characteristics of good stability and low equipment cost.

[0007] The technical solution of this utility model is as follows: A right-angle door elevator with adjustable door opening size includes a car body. Side-opening car door assemblies and center-parting car door assemblies are respectively provided on the two side walls of the car body. The side-opening car door assemblies and center-parting car door assemblies are arranged perpendicularly to each other. A car frame assembly is connected to the outside of the car body. The car frame assembly includes a first car top beam and a second car top beam that overlap and intersect each other. The two ends of the first car top beam are connected to a car bottom frame located below the car body via tie rods. The two ends of the second car top beam are connected to the car bottom frame via vertical beams. The car body forms an inwardly recessed opening at the angle between the side-opening car door assembly and the center-parting car door assembly. The vertical beam at one end of the second car top beam extends through the opening to the bottom of the car body.

[0008] In the aforementioned right-angle door elevator with adjustable door size, a car top wheel is connected to the top of the first car top beam.

[0009] In the aforementioned right-angle door elevator with adjustable door size, one end of the side-opening car door assembly extends to the outside of the car body and forms a retractable section. A counterweight device is provided on one side of the retractable section, located in the elevator shaft. The counterweight device and the car body are arranged parallel to each other.

[0010] In the aforementioned right-angle door elevator with adjustable door size, the car body forms an outwardly protruding car door mounting bracket on the side near the side-opening car door assembly. The side-opening car door assembly is connected to the car body via the car door mounting bracket, and an opening is formed between the car door mounting bracket and the side wall of the car body.

[0011] In the aforementioned right-angle door elevator with adjustable door size, the car body has tie rod grooves at the end corners near the retractable section and away from the retractable section, and the lower end of the tie rod passes through the tie rod groove to connect to the car bottom frame.

[0012] Compared with the prior art, this utility model has the following characteristics:

[0013] (1) By limiting the structure of the car frame assembly, this utility model can simultaneously support the four corner positions of the car body, thereby effectively improving the stability of the car during the lifting process; by opening the corner of the car body, the vertical beam on one side of the car frame assembly can extend through the opening to the bottom of the car body and connect to the car bottom frame, thereby effectively reducing the occupation of the shaft space; and with the above combination, this utility model can use the side-opening car door assembly and the center-split car door assembly as the two car doors, that is, compared with the existing right-angle elevator, it effectively reduces its equipment cost and avoids forming a chamfer in the internal space of the car.

[0014] (2) By extending one end of the side-opening car door assembly to the outside of the car body and installing the counterweight device in the elevator shaft on one side of the side-opening car door assembly, the internal space of the elevator shaft can be effectively utilized. At the same time, by limiting the installation position of the car frame assembly, it will not occupy the space of the elevator shaft in the depth direction. Thus, under the above combination, this utility model can effectively improve the space utilization rate of the elevator shaft and reduce the requirements for the size of the shaft space.

[0015] Therefore, this utility model has the characteristics of good stability and low equipment cost. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example. A right-angle door elevator with adjustable door opening size, configured as follows: Figure 1 As shown, the system includes a car body 1. Side-opening car door assemblies 2 and center-parting car door assemblies 3 are respectively installed on the two side walls of the car body 1. The side-opening car door assemblies 2 and center-parting car door assemblies 3 are arranged perpendicularly to each other. A car frame assembly is connected to the outside of the car body 1. The car frame assembly includes a first car top beam 4 and a second car top beam 5 that overlap and intersect each other. The two ends of the first car top beam 4 are connected to a car bottom frame 7 located below the car body 1 via tie rods 6. The tie rods 6 are long, round rods. The car bottom frame 7 is a frame structure that supports the bottom of the car body 1. The two ends of the second car top beam 5 are connected to the car bottom frame 7 via vertical beams 8. The car body 1 forms an inwardly recessed opening 9 at the angle between the side-opening car door assemblies 2 and the center-parting car door assemblies 3. The vertical beam 8 at one end of the second car top beam 5 extends through the opening 9 to the bottom of the car body 1. The outside of the two vertical beams 8 are connected to guide rails located in the elevator shaft via elevator guide shoes.

[0022] The top of the first car top beam 4 is connected to a car top wheel 10. The car top wheel 10 is located at the center of gravity of the car body 1 in the horizontal direction. Balance blocks can be installed on both sides of the car body 1 except for the car door, so that the center of gravity of the car body 1 is located at the center of the car body 1.

[0023] One end of the side-opening car door assembly 2 extends to the outside of the car body 1 and forms a retractable section. A counterweight device 11 located in the elevator shaft is provided on one side of the retractable section. The counterweight device 11 and the car body 1 are arranged parallel to each other.

[0024] The car body 1 has an outwardly protruding car door mounting bracket 12 on the side near the side-opening car door assembly 2. The side-opening car door assembly 2 is connected to the car body 1 via the car door mounting bracket 12, and an opening 9 is formed between the car door mounting bracket 12 and the side wall of the car body 1.

[0025] The car body 1 has a tie rod groove at one end near the retractable part and the other end away from the retractable part. The tie rod groove can be formed by drilling directly in the middle of the car wall or the car door mounting bracket 12, or it can be a groove formed in the car wall after assembly. The lower end of the tie rod 6 passes through the tie rod groove and connects to the car bottom frame 7. The two ends of the tie rod 6 are respectively fixed to the first car top beam 4 and the car bottom frame 7 by nuts.

[0026] The working principle of this utility model is as follows: This utility model provides a side-opening car door assembly 2 and a center-parting car door assembly 3 on both sides of the car body 1, and extends one end of the side-opening car door assembly 2 into the elevator shaft outside the car body 1 to form a retractable part. This allows the car body 1 to form an opening at the angle between the side-opening car door assembly 2 and the center-parting car door assembly 3 to accommodate the vertical beam 8. This reduces the space occupied by the vertical beam 8 on the outside of the car body 1 after installation, and does not obstruct the center-parting car door assembly 3.

[0027] By connecting the first car top beam 4 to the car bottom frame 7 via a round rod 6, and by opening rod grooves at both corners of the car body 1 for the rod 6 to pass through, the rod 6 can avoid occupying the shaft space outside the car body 1. With the above-mentioned combination, this utility model can, on the one hand, use the cooperation of the first car top beam 4, the second car top beam 5 and the car bottom frame 7 to support the four corners of the car body 1, thereby reducing the swaying of the car during the lifting and lowering process; on the other hand, it can reduce the occupation of the car frame in the shaft space outside the car, thereby reducing the required elevator shaft space and improving its space utilization rate.
