Description

Technical Field

[0001] The utility model belongs to the technical field of civil elevator equipment, and in particular relates to a civil linear guide screw elevator. Background Art

[0002] At present, there are still a considerable number of multi-storey (6-storey or less) residential buildings in China. With the aging of the population, stairs have become a travel obstacle for the elderly and people with mobility difficulties. However, the residential buildings built in the 1980s and 1990s are still within their effective service life. The cost of demolishing and rebuilding is too high, which also wastes resources. Based on this situation, it has become a necessary trend to install elevators in old multi-storey buildings.

[0003] Generally, when installing elevators in old residential buildings, entrances are often opened on each floor. Although this seems to make it easier for the elderly and the sick to go up and down the stairs, it actually poses a great safety hazard. Because many old residential buildings are very old and have dilapidated walls, cutting too many and too dense openings on the exterior walls is also a kind of damage to the building itself. In addition, the personnel and belongings in old residential buildings are complicated, and cutting too many entrances requires a lot of construction, many uncertain factors, and a lot of coordination with residents, which greatly increases the time and money costs. In addition, the stability and safety of the traditional elevators installed in old residential buildings also have a lot of room for improvement.

[0004] The Chinese invention with application number 202011359684.6 discloses a method of retrofitting an elevator and adding a staggered-floor entrance to residential buildings in old communities, comprising a car arranged on the outside of the residential building, a traction mechanism for driving the lifting and lowering movement of the car, and a plurality of derrick columns for slidingly supporting the car. The residential building comprises a building exterior wall, a rest platform, an entrance platform, a resident door, an upward staircase, a downward staircase and a unit door awning. A plurality of buckling mechanisms are arranged between the building exterior wall and the derrick columns, and an entrance corresponding to the position and size of the car door is opened on each even-numbered floor of the building exterior wall, and the entrance leads to the rest platform.

[0005] The Chinese invention patent application with application number 201710440748.7 discloses an elevator scheme with an openable and closable passage. In addition to the elevator bridge door, an openable and closable passage is added on the side of the elevator bridge. When the elevator is running, the side wall is close to the bridge passage and closed. When it reaches the predetermined floor, the passage opens and connects with the floor elevator entrance. The elevator does not pass directly through the floor elevator entrance when it is not parked, and the elevator bridge door can only be opened for passage when it is on the ground floor. This provides a convenient and practical optional solution for adding elevators to residential buildings in old communities that is adapted to local conditions.

[0006] The above-mentioned transformation solutions in the prior art are all vertical lifting solutions, which inevitably require opening an entrance on the building. This solution has a destructive effect on the building strength of old communities and also affects the first and second floors that do not need elevators. It is often not promoted because the residents on the first and second floors do not agree. In addition, this type of external span elevator has a huge investment and the residents cannot afford it.

The motor 13 is connected to the end of the screw rod 9 through the reducer 14 and the universal coupling 15 through flanges and bolts. The car 2 is transparent from front to back and has no door. Its top is suspended on the car support plate 11. The doorless design can avoid the inconvenience and safety hazards caused by the inability to open the car door when the elevator fails. The car 2 is equipped with a command control box 23 and a handrail 20 for easy operation and use. The car 2 is suspended on the main frame 1 and has no contact with the surface of the stair steps. The car 2 is formed by stainless steel pipes and plates to ensure ventilation and light transmission. The linear guide 8 can be a single guide rail or a double guide rail structure. In the embodiment, it is a double guide rail, which has the advantage of balanced force.

[0032] An extended upper frame 16 is provided at the entrance and exit of the upper frame 4. An extended lower frame 17 is provided at the entrance and exit of the lower frame 5, and a guide pedal 18 is provided on the extended lower frame 17. The functions of the extended upper frame 16 and the extended lower frame 17 are to improve the installation strength of the main frame 1 and increase the connection area with the building. The extended lower frame 17 can also reduce the height difference between the car 2 and the ground, which is convenient for use. The transmission mechanism 3 is arranged on the middle beam 19 of the extended upper frame 16 on the high side to reduce the occupied space of the effective channel.

[0033] In order to maximize the effective space of the passage and avoid the adverse effects of the elevator on the daily residents going up and down the stairs, the widest outer dimensions of the upper frame 4 and the lower frame 5 are flush with the outer contour of the stairway beam 7. The main frame 1 is formed by processing metal steel and the surface is electrostatically sprayed. The linear guide 8 is an I-shaped guide, and the slider 10 is processed into a C shape with 45# square steel. The slider 10 is matched with the linear guide 8 and is slidably connected.

The limit switches are respectively set on the upper limit and lower limit of the linear guide 8; the weight sensor is set on the car support plate 11; the emergency stop switch 22 is set on the command control box, and the command control box 23 is set in the car 2. When the car 2 is overweight, the alarm light flashes and the car does not run.

[0035] The utility model is a manufacturing process of a civil linear guide screw elevator, comprising the following steps:

[0036] 1) Cut the metal profiles for the main frame 1 according to the specifications and sizes in the drawings, and after processing, perform surface treatment and electrostatic spraying, and assemble them into a steel structure main frame;

[0037] 2) Install the pre-processed parts, such as the bearing seat 21, the linear guide 8, the slider 10, the screw 9, the screw nut 12, the reducer 14, the motor 13, the car support plate 11 and the car 2, at the designated positions respectively;

[0038] 3) The left and right sides of the linear guide rail 8 are processed into grooves, and the inner side of the slider 10 is processed into a boss, which is installed on the linear guide rail for active fit, and the two linear guide rails 8 are installed on the upper frame 4;

[0039] 4) The screw rod 9 is fixed on the upper frame 4 with a bearing seat 21, located between the two linear guide rails 8, and the reducer 14 is installed first, and then the motor 13;

[0040] 5) The car support plate 11 is hoisted on four sliders 10 to form a whole, the car 2 is hoisted on the car support plate 11, and the screw nut is fixed on the upper surface of the car support plate 11;

[0041] 6) When the motor 13 is started, the screw 9 rotates, and the car moves up and down freely, and stops automatically at the upper and lower limit positions; the elevator uses linear guides 8 and screws 9 to rotate. All parts of the elevator can only be installed after they have passed the processing inspection. After the installation is completed, they will be inspected again. After passing the inspection, they can be powered on and debugged before they can be put into operation.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
