Abstract
Description
Technical Field
[0001] The present invention relates to a civilian open-type residential walking lift, in particular to a civilian lift used for renovation of residential buildings in old communities, and belongs to the field of passenger elevator design and manufacturing. The present invention belongs to the field of special equipment elevator industry. Background Art
[0002] At present, old-style houses without elevators can no longer meet people's growing demand for use. In order to improve people's existing living environment and enhance the use function of existing houses, installing elevators has become the focus of the renovation of old buildings in cities. Under the current technical conditions, installing elevators in old buildings means installing a prefabricated steel structure shaft in front of the building unit door, installing a standard elevator inside, and connecting the corridor to the stairwell as the elevator exit. Figure 1 As shown in the figure, the traditional standard elevator is a double-rail type, and the car and counterweight need to be equipped with T-shaped rails respectively. Therefore, the prefabricated steel structure shaft used in it has a long construction period and high installation cost. At the same time, it is necessary to modify the manhole at the door of the unit, occupying the already very tight passage space, and may even affect the smooth flow of the fire escape. In addition, due to the inconsistency between the self-weight of the later installed elevator and the steel structure shaft and the settlement coefficient of the rigid connection of the building, it may cause a series of hidden dangers in the operation of the elevator and the stability of the building. Summary of the invention
[0003] The purpose of the present invention is to provide a civilian mobility lift suitable for the renovation of old buildings, to provide an open and rotatable residential mobility lift, to make full use of the space on the left and right sides of the unit door, to use the elevator combination guide rail as the main guiding and load-bearing structural component of the mobility lift, to use the idle space at the unit door as a base station, the opening direction of the base station is perpendicular to the unit door, the normal entry and exit of the original unit door is not changed, and a protected base station is only provided on the first floor of the building, and all floors above are open, which greatly reduces the cost.
[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:
[0005] An open and rotatable residential mobility elevator comprises a car, a combined guide rail, a drive system, a double-fold side-opening car door, a brake-type steering mechanism, a car frame mechanical locking device, and a rotating shaft combination. The car can be reciprocated in the vertical direction by the drive system and is installed on the outer wall of the building that needs to be renovated through a support system. When the elevator is running, the brake-type steering mechanism loses power and locks. When the elevator rises to the target floor, the brake-type steering mechanism and the car frame mechanical locking device open, and drive the car to rotate 90 degrees before stopping and locking. The car door and floor door open, and passengers can enter and exit the car.
[0006] After the passengers enter and exit, the floor door and car door are closed, the brake-type steering mechanism starts to work, and stops after rotating 90°. The car frame mechanical locking device locks the car and the car frame for standby use.
[0007] The combined guide rail adopts a relatively high-strength H-steel as the main rail of the elevator car, and the T-rail is the counterweight auxiliary rail. The combined guide rail is composed of H-steel, main and auxiliary guide rail brackets, pressure plates, main and auxiliary guide rail connectors, fasteners, and T-rails for counterweights. The combined guide rail composed of H-steel is fixed to the outer wall of the building through a bracket, so that the elevator is perfectly combined with the building and the steel structure shaft is eliminated.
[0008] The addition of the brake-type steering mechanism is different from that of conventional elevators and is an important part of the present invention. The brake-type steering mechanism adopts a gear reducer with a large ratio, stable speed and small inertia, and has its own braking system, which ensures that the car is accurately in place and can meet the use requirements of the equipment.
[0009] The car frame mechanical locking device comprises a fixed shaft, a hook and an electromagnet, and is a safety device added when the car is reset to ensure the overall reliability of the vertical operation of the elevator.
[0010] The rotating shaft assembly is composed of a self-locking rotating mechanism, a bearing seat assembly, and a car fixed shaft clamp. Due to the slow speed, this part only rotates a quarter of a circle, and it only needs to have sufficient strength and flexibility.
[0011] The signal automatic control system of the elevator is controlled by a microcomputer, which meets all the requirements of conventional elevator technical requirements and the national elevator technical standard (GB7588), except that it adds a steering mechanism (5) and an associated car frame mechanical locking device (10) that are different from ordinary elevators. The electric control system of the elevator has its own UPS backup power supply, which automatically turns on when a power outage occurs to ensure the normal use of lighting, drive host and door machine, and release the trapped people.
[0012] Furthermore, the drive system includes 3 drive systems and 5 brake-type steering mechanisms (the steering mechanism is an NMRV worm gear reducer with a built-in brake device).
[0013] Furthermore, the flat-opening landing door is arranged on the outer wall of the building and opens inwards, making full use of the wall thickness, and is modified from the position of the ventilation window of the existing stairwell step platform. Furthermore, when the brake steering mechanism drives the car to rotate, the steering space used is the external space of the building.
[0014] Compared with the prior art, the following beneficial effects can be achieved by using the technical solution described in the present invention:
[0015] 1. The idle space on both sides of the unit door is used as the base station. The door opening direction is perpendicular to the unit door, which does not affect or change the original normal entry and exit, ensuring the smooth flow of fire passages;
[0016] 2. Since the elevator is open, only one floor is equipped with protection and door, and there is no need to set up a shaft above the first floor, which shortens the construction period and greatly reduces the cost, which can reach about 50% of the cost of installing an ordinary elevator. After rising, it rotates 90° and stops, making use of the existing idle space on the building's outer wall, occupying a small ground area;
[0017] 3. This elevator is traction type, and the control system and electric traction are the same as those of elevators. The safety measures are equal to or even greater than those of standard elevators, and the reliability is high;
[0018] 4. This elevator adopts a new guide rail structure. The combined guide rail is a core component of the present invention. It uses H-steel as the main guide rail of the car and T-rail as the counterweight auxiliary guide rail. The main and auxiliary rails are combined together by connectors. It has high strength and compact structure. It is directly installed on the outer wall of the building through the guide rail bracket, which reduces the commonly used steel structure hoistway, greatly reduces installation restrictions and construction period, makes full use of the building outer wall, and greatly reduces the overall cost;
[0019] 5. The elevator hall door adopts a single-leaf swing door with a simple structure, low failure rate, and good airtightness and thermal insulation performance. Since the swing hall door is installed on the outside of the building, it fully utilizes the thickness of the wall and does not occupy or occupies less space on the stair landing, ensuring normal traffic in the stairwell.

DETAILED DESCRIPTION
[0028] An open and rotatable residential mobility elevator comprises a car 7, a combined guide rail 4, a driving system 3, a double-folding side-opening car door 8, a brake-type steering mechanism 5, a mechanical locking device 10 for a car frame, and a rotating shaft combination. A double-folding side-opening door enclosure 18 on the first floor is fixedly arranged on the outer wall of the first floor building, and a buffer 16 is installed at the lower end of the double-folding side-opening door enclosure 18 on the first floor. The combined guide rail 4 adopts a high-strength H-steel as the main guide rail 24 of the elevator car, and the T-rail is the counterweight auxiliary guide rail 19. The combined guide rail is composed of the main guide rail 24 of the car, the main guide bracket 22, the pressure plate 23, the main and auxiliary guide rail connector 20, the fastener 21, and the counterweight auxiliary guide rail 19. The combined guide rail 4 composed of H steel is fixed to the outer wall of the building through the main guide bracket 22, so that the elevator is perfectly combined with the building body, eliminating the steel structure shaft.
[0029] The car 7 can be reciprocated in the vertical direction through the drive system 3 and installed on the outer wall of the building that needs to be modified through the support system. When the elevator is running, the brake-type steering mechanism 5 loses power and is locked. When the elevator rises to the target floor, the brake-type steering mechanism 5 and the mechanical locking device 10 of the car frame are opened, and the car is driven to rotate 90° and then stop and lock. The double-fold side-opening car door 8 and the floor door 9 are opened, and passengers can enter and exit the car.
[0030] After the passengers enter and exit, the floor door 9 and the double-folding side-opening car door 8 are closed, the brake-type steering mechanism 5 starts to work, rotates 90° and stops, and the car frame mechanical locking device 10 locks the car 7 and the car frame 1 for standby use.
[0031] The addition of the brake-type steering mechanism 5 is different from that of conventional elevators and is an important part of the present invention. The brake-type steering mechanism 5 adopts a gear reducer with a large ratio, stable speed and small inertia, and has its own braking system, which ensures that the car is accurately in place and can meet the use requirements of the equipment.
[0032] The mechanical locking device 10 of the car frame includes a fixed shaft 25, a hook 26 and an electromagnet 27. It is a safety device added when the car 7 is reset to ensure the overall reliability of the vertical operation of the elevator (see attached Figure 7).
[0033] The rotating shaft assembly is composed of a brake-type steering mechanism 5, a bearing seat assembly 11, and a car fixed shaft clamp 12 (see attached Figure 3 ), this part only rotates a quarter of a turn due to the slow speed, and it is enough to have sufficient strength and flexibility.
[0034] like Figure 4 As shown in the figure, the elevator car 7 and the flat-opening elevator landing door 9 are installed on the wall at the original ventilation window position of the floor step platform. The landing door 9 is installed on the outside of the stairs and opens flatly to the inside of the building, making use of the wall thickness to reduce the space occupied by the step platform. The elevator adopts a combination of H-shaped steel and T-shaped rails, as shown in the attached figure. Figure 6 As shown, the counterweight auxiliary guide rail 19 is connected to the car main guide rail 24 through the main and auxiliary guide rail connectors 20 and fasteners 21 to form a combined guide rail. The car main guide rail 24 is directly attached to the building wall with through-wall bolts using the main rail bracket 22 and the pressure plate 23, which saves space and is consistent with the building settlement coefficient. The H-shaped steel replaces the existing elevator T-shaped guide rail to reduce the number of guide rails from two to one, thereby avoiding the shaft limitation of the elevator installation. During use, the mechanical properties of the H-shaped steel need to be checked and the car guide structure needs to be adjusted to meet the use.
[0035] Different from the traditional elevator fixed car structure, the elevator car 7 is connected to the car frame 1 through the shaft 6, and a 90° brake-type steering mechanism 5 is arranged on the top of the car frame and connected to the shaft 6 to provide the car 7 with rotation power; (Structural diagram is attached) Figure 3 ) A mechanical locking device 10 is provided at the connection between the car frame 1 and the car 7. The mechanical locking device 10 is interlocked with the brake-type steering mechanism 5. When the elevator is running, the drive system 3 is started, and the mechanical locking device 10 is locked. When the elevator rises to the target floor, the drive system 3 brakes, and the mechanical locking device 10 of the car frame receives the brake signal to open, and the brake-type steering mechanism 5 is energized. After the car rotates 90°, the brake-type steering mechanism 5 is powered off and self-locked, and the double-folding side-opening car door 8 receives the opening signal to start, and at the same time, the opening floor door 9 is triggered to start and open. After the passengers have finished entering and exiting, the opening floor door 9 is closed, and at the same time, the double-folding side-opening car door 8 is closed and a signal is triggered, and the brake-type steering mechanism 5 is energized. After the car rotates 90° back to the original position of the car frame, the mechanical locking device 10 of the car frame is started and locked, and the brake-type steering mechanism 5 is powered off and on standby.
