Description

Technical Field

[0001] This utility model relates to the field of elevators, and in particular to an arrangement structure of the drive unit in a forced-drive home elevator. Background Technology

[0002] Currently, the main locations of the drive unit in forced-drive home elevators on the market are either external or internal to the shaft. In externally mounted forced-drive home elevators, the drive unit is located on the outside of the shaft, requiring customers to prepare dedicated installation space for it. This layout is inflexible and takes up valuable home space. In some cases, it may even require drilling holes in the wall to house the drive unit, which is very inconvenient. Furthermore, a guide wheel structure needs to be installed at the top of the shaft, with the traction rope wound around the guide wheel from the car's frame before connecting to the drive unit's rollers. This reduces the space utilization of the shaft and places higher requirements on the shaft's height. In a shaft-integrated forced-drive home elevator, the drive unit is located at the bottom or top of the shaft. For some forced-drive home elevators with the drive unit located at the top of the shaft, it needs to be reinforced with the customer's floor slab. Space needs to be left at the top of the shaft for installing the drive unit. One end of the traction rope is connected upwards to the roller of the drive unit, and the other end is connected downwards to the car frame. For some forced-drive home elevators with the drive unit located at the bottom of the shaft, space needs to be left at the bottom of the shaft for installing the drive unit, and space also needs to be left at the top of the shaft for installing guide wheels. After the traction rope is wound around the guide wheels, both ends of the traction rope are connected downwards to the roller of the drive unit and the car frame, respectively. Although shaft-integrated forced-drive home elevators do not occupy additional living space for the customer, they will occupy a large amount of space at the top or bottom of the shaft. Compared to externally mounted forced-drive home elevators, shaft-integrated forced-drive home elevators have higher requirements for shaft height, requiring an increase in shaft height to achieve installation. Therefore, externally mounted forced-drive home elevators require additional openings, increasing installation costs, while internally mounted forced-drive home elevators require increasing the height of the shaft, which also increases installation costs. Utility Model Content

[0003] The purpose of this utility model is to provide an arrangement structure for the forced drive host in a forced drive home elevator, which places the forced drive host in the shaft without reducing the utilization rate of the shaft space.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an arrangement structure for a forced drive main unit in a home elevator, comprising: a shaft with a shaft frame and a car backpack frame, a car mounted on the car backpack frame, the car backpack frame being slidably locked in the shaft frame, a forced drive main unit being mounted in the car backpack frame, the forced drive main unit not interfering with the car, a traction rope fixed on the rollers of the forced drive main unit, a rope head beam fixedly installed above the car backpack frame, and the traction rope being fixedly connected to the rope head beam.

[0005] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced drive home elevator, the forced drive host is fixed on the bottom wall of the car backpack frame and located at the rear of the car. The roller in the forced drive host extends rearward from the car backpack frame, and the traction rope on the roller is vertically upward and connected to the rope head beam.

[0006] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced drive home elevator, the forced drive host is a double-ended structure, with rollers provided at both ends of the forced drive host. The left and right symmetrical center lines of the forced drive host are aligned vertically with the left and right symmetrical center lines of the bottom wall of the car backpack frame. The two traction ropes on the two rollers of the forced drive host are vertically upward and connected to the rope head beam.

[0007] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced drive home elevator, two rope head seats are symmetrically arranged on the rope head beam. The two rope head seats are respectively aligned vertically with two rollers extending rearward from the car backpack frame, and the traction ropes on the two rollers are respectively connected to the two rope head seats on the rope head beam.

[0008] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced drive home elevator, the rope head beam is fixed to the top of the shaft frame.

[0009] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced drive home elevator, the rope head beam is fixed to the top wall of the shaft.

[0010] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced drive home elevator, guide shoes are provided at both the upper and lower ends of the left and right side walls of the car backpack frame, and a sliding groove is provided in the shaft frame to slide and cooperate with the two guide shoes on the same side.

[0011] Furthermore, in the aforementioned arrangement structure of the forced drive host in a forced-drive home elevator, the traction rope is a steel wire rope.

[0012] The advantages of this utility model are as follows: by setting the main drive unit on the car backpack frame, it is only necessary to fix the traction rope to the rope head beam in the shaft. There is no need to set a guide wheel structure at the top of the shaft, and therefore no need to occupy the space at the top or bottom of the shaft, which improves the space utilization of the shaft. Compared with the traditional shaft-built forced drive home elevators on the market, it does not require increasing the shaft height, reducing the height requirements of the shaft. It also does not require additional openings like the shaft-external forced drive home elevators, which greatly reduces the installation difficulty and cost of home elevators.

[0015] Figure 3 This is a schematic diagram of another embodiment of the arrangement structure of the forced drive host in a forced drive home elevator according to this utility model. Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] like Figure 1 , Figure 2As shown, the arrangement structure of the forced drive host in a forced drive home elevator according to this utility model includes: a shaft 1 with a shaft frame 2 and a car carrier frame 3. A car is installed on the car carrier frame 3. Installing the car on the car carrier frame 3 is prior art and is not shown in the figure. Guide shoes 31 are provided at the upper and lower ends of the left and right side walls of the car carrier frame 3. A sliding groove 21 is provided in the shaft frame 2 to slide and engage with the two guide shoes 31 on the same side. The guide shoes 31 on the car carrier frame 3 are slidably engaged in the sliding groove 21 on the corresponding side, thereby allowing the car to move freely. The car backpack frame 3 can stably rise and fall within the hoistway frame 2. A forced-drive unit 4 is installed within the car backpack frame 3. The forced-drive unit 4 has a double-ended structure, with rollers 41 on both its left and right ends. The forced-drive unit 4 is fixed to the bottom wall of the car backpack frame 3 and located at the rear of the car. The forced-drive unit 4 does not interfere with the car. Because the front-to-back width of the hoistway 1 is greater than the front-to-back width of the hoistway frame 2, a gap is left between the hoistway frame 2 and the rear wall of the hoistway 1. When the car backpack frame 3 is slidably positioned within the hoistway frame 2, the car backpack frame... There is also a gap between the rear end of the shaft frame 2 and the drive unit 3, so when the drive unit 4 is fixed on the car backpack frame 3 located at the rear of the car, there is a large gap between the drive unit 4 and the rear wall of the shaft 1. The two rollers 41 in the drive unit 4 extend backward out of the car backpack frame 3, and the two rollers 41 on the drive unit 4 will not interfere with the rear wall of the shaft 1. The left and right symmetrical center lines of the drive unit 4 are aligned vertically with the left and right symmetrical center lines of the bottom wall of the car backpack frame 3, and the drive unit 4 is located at the left and right symmetrical center of the car backpack frame 3. To ensure the balance of the car backpack frame 3, traction ropes 5 are fixed on both rollers 41. In this embodiment, the traction ropes 5 are steel wire ropes. The connection structure between the traction ropes 5 and the rollers 4 is existing technology and will not be described in detail here. A rope head beam 6 is provided at the top of the hoistway frame 2. Two rope head seats 61 are symmetrically arranged on the rope head beam 6. The two rope head seats 61 are respectively aligned vertically with the two rollers 41 that extend backward from the car backpack frame 3. The traction ropes 5 on the two rollers 41 are vertically connected to the two rope head seats 61 on the rope head beam 6.

[0018] When the drive unit 4 drives the two rollers 41 to rotate in the forward direction, the two traction ropes 5 are wound onto the corresponding rollers 41 respectively. When the traction ropes 5 are wound, they will drive the drive unit 4 and the car backpack frame 3 to rise together. The car backpack frame 3 is used to install the car, so the car in the elevator can rise. When the drive unit 4 drives the two rollers 41 to rotate in the reverse direction, the traction ropes 5 will be released, and the drive unit 4 and the car backpack frame 3 will descend together, and the car in the elevator will descend.

[0019] If the customer's home has limited height space, the rope head beam 6 can be fixed to the top wall of the shaft 1, see [reference]. Figure 3This will further save space in shaft 1.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
