Description

Technical Field

[0001] This invention relates to the field of elevator installation technology, and more specifically to a precise elevator motor installation device. Background Technology

[0002] Machine room-less elevator motor installation devices are specialized fixing equipment adapted to designs without a separate machine room. They are mostly installed on the top or side of the shaft and are used to accurately position and fix the drive motor. The adjustable installation structure is adapted to motors of different power. Integrated shock-absorbing and anti-loosening components reduce operating noise and vibration transmission. High-strength materials are used to balance load-bearing capacity and ease of installation, and the entire process complies with the space limitations and safety regulations of the elevator shaft.

[0003] Chinese patent CN119349483A discloses a working platform for elevator installation, including a base plate, a pair of support plates fixed to the top of the base plate, and a top plate fixed to the top of the two support plates. Slider blocks are fixed to both sides of the platform, forming a sliding connection between the sliders and their corresponding support plates. A cable is fixed to the top of the slider, with the other end of the cable passing through the top plate and connected to a drum. A pair of bearing seats are fixed to the top of the top plate, with a transverse shaft rotatably connected to each bearing seat. The drum is fixedly sleeved on the shaft. Supports are fixed to both sides of the top plate, with a motor fixed to the top of each support. The motor output shaft is fixedly connected to the end of the shaft. A pair of brackets are fixed to the top of the top plate, with fixed pulleys rotatably connected to each bracket. Two sets of anti-fall mechanisms are provided on the top of the top plate. In this device, when the motor malfunctions and the safety measures fail, the platform will fall. At this time, the anti-fall mechanisms will press the cable against the brackets, thereby slowing down the platform's fall speed. However, this device still has the following problems: When installing motors without a machine room, the platform can only move the motor to a position below the installation location due to its height. Workers still need to lift and move the motor to the installation location. Furthermore, the elevator shafts of high-rise buildings are tens of meters deep, and the device cannot push the platform to the corresponding height.

The horizontal moving component 71 is used to push the elevator motor 8 to move horizontally through the vertical moving component 72. The vertical moving component 72 is used to place the elevator motor 8 and, after reaching the installation position, drive the elevator motor 8 to be placed in the installation position. The vertical moving drive component 73 is used to drive the first base 1, the second base 2, the third base 3, the fourth base 4, the horizontal moving component 71, and the vertical moving component 72 to move up and down in height. The second base 2 and the vertical moving component 72 are both connected to the horizontal moving component 71. The vertical moving drive component 73 is connected to the second base 2.

[0015] In this invention, the operator moves the device and elevator motor 8 into the elevator shaft using the casters 5. Then, the size adjustment mechanism 6 drives the first base 1, the second base 2, the third base 3, and the fourth base 4 to adaptively adjust and install according to the dimensions of the motor shaft and the elevator guide rail. After installation, the vertical movement drive assembly 73 drives the entire device to move upward along the elevator guide rail to the motor installation height. Then, the horizontal movement assembly 71 pushes the elevator motor 8 horizontally above the installation position of the elevator motor 8 through the vertical movement assembly 72. Then, the vertical movement assembly 72 drives the elevator motor 8 to move downward and place it in the installation position, thus achieving the positioning and installation of the elevator motor 8 and saving manual labor.

[0016] Example 2: In some embodiments, such as Figures 1-6 As shown, in a preferred embodiment of the present invention, the transverse component 71 includes a limiting slide rail and slider assembly 711, a horizontal plate 712, a second screw 713, a handle 714, and a fixing plate 715; two sets of limiting slide rails and slider assemblies 711 are distributed front and rear; the fixed ends of both sets of limiting slide rails and slider assemblies 711 are fixedly connected to the second base 2; the moving ends of both sets of limiting slide rails and slider assemblies 711 are fixedly connected to the same horizontal plate 712; the horizontal plate 712 is rotatably connected to one end of the second screw 713; the other end of the second screw 713 is fixedly connected to the handle 714; the second screw 713 is threadedly connected to the fixing plate 715; and the fixing plate 715 is fixedly connected to the second base 2.

In this invention, an external winch drives the second base 2 to move upward under the limit of the size adjustment mechanism 6 via a fixed pulley 731 and a cable 732. After moving to the installation height, the operator rotates the second screw 713 via the handle 714. The rotation of the second screw 713 pushes the horizontal plate 712 to slide at the limit of the limit rail and the slider assembly 711, so that the vertical moving frame 721 approaches the installation position of the elevator motor 8 under the limit of the limit rail and the slider assembly 711. When the elevator motor 8 is above the installation position, the operator stops rotating the handle 714 and drives the vertical moving frame 721 to move downward under the limit of the third limit rod 723 via the screw jack 722 until the elevator motor 8 bracket placed on the placement frame 724 abuts against the installation position and the elevator motor 8 is supported by the installation position. Then, the screw jack 722 continues to drive the placement frame 724 to move downward through the vertical moving frame 721 to avoid the elevator motor 8, and then the operator rotates the handle 714 to reset, thus achieving precise installation of the elevator motor 8.

[0018] In this invention, the operator moves the device and elevator motor 8 into the motor shaft using the casters 5. Then, the first push cylinder 611 is activated to push the first base 1 and the second base 2 away from the limit of the first limit rod 612. At the same time, the first screw 621 drives the third base 3 and the fourth base 4 away from the limit of the second limit rod 613 until the first roller 631 and the second roller 632 are located on the front and rear sides of the elevator guide rail. Then, by turning the two nuts 622, the third base 3 is moved to slide against the limit of the first screw 621, so that the third base 3 and the fourth base 4 are brought closer together.
