Efficient and energy-saving cordless elevator

Abstract

An efficient and energy-saving elevator is composed of a screw rod, a motor, a sliding support, an H-shaped bearing, a fixing square strip, a sliding hoop and the like. According to the driving mode, the whole support is directly pulled through positive and negative rotation of the screw to drive the elevator room to ascend and descend, so that noise caused by multiple gears of a reduction gearbox is eliminated, the full-motion efficiency is improved, the screw is parallel to the H-shaped bearing and the square strip frame, the meshing face can be increased, and the tension strength is improved; due to the fact that the elevator can rotate and different racks are fixed, resistance, abrasion and noise are reduced, the elevator can be driven by a motor with low power efficiency, and the elevator is simple in structure, high in safety degree, free of various parts of a brake part and capable of reducing power consumption by several times compared with similar elevators. And a good foundation is laid for developing high-efficiency, energy-saving and low-noise elevators.

Description

Technical Field

[0001] The invention relates to electromechanical energy saving Background Art

[0002] There are several types of existing elevators: the hydraulic and screw types are high in cost and have limited height, and the rack and pinion types have noise problems, etc. Most high-rise buildings use wire rope types, which are pulled by several wire ropes and require many components such as reduction gearboxes and brakes. The biggest disadvantage is that the wire ropes wear out quickly and need to be replaced frequently, because the wire ropes rotate and straighten when they work, so they need to be replaced if they are not used for a long time. If they are not replaced, they will be unsafe, so the maintenance cost is very high. In addition, the above elevators require reduction gearboxes, several rotating wire ropes and brakes, which increases power consumption and fails to achieve energy-saving effects. Summary of the invention

[0003] In order to solve the above problems, I invented an efficient and energy-saving ropeless elevator. A screw and H-type bearing can directly drive the elevator room to rise and fall after the engagement and rotation. The structure consists of: 1 screw, 2 screw bearing, 3 motor, 4 sliding bracket, 5 H-type bearing, 6 fixed shaft, 7 fixed square bar, 8, 9 sliding clamps, 10, 11, 12 fixed nails. The characteristics are: 1. The rotation of the screw directly drives the bracket to rise and fall, the screw and the square bar of the H-type bearing are parallel to each other to increase the joint surface area, the screw and the motor shaft are connected and there is no need for a speed reduction part and a large gear, which greatly improves the transmission efficiency. In addition, many H-type bearings are used to replace traditional racks. Because the bearings can rotate, it can reduce wear, improve efficiency and noise caused by rotation, and its shaft is installed on the fixed square bar. Although many H-type bearings are used, the cost is the same as that of the rack, because it rotates instead of sliding and is not easy to wear, and it works in turns, with several bearings working at a time, so the annual maintenance cost is low. As can be seen from the figure below, it is easy to install and does not require brakes. It is safe and reliable. As long as the screw stops rotating, the entire elevator frame will not move, achieving the function of automatic braking.

[0004] Description of the drawings: Figure 1 This is a schematic diagram of the present invention, in which: 1 screw; 2 screw bearing; 3 motor; 4 sliding bracket; 5 H-type bearing; 6 fixed shaft; 7 fixed square bar; 8 and 9 slidable clamps; 10, 11, 12 fixed nails

[0005] Specific implementation plan: The screw 1 is coaxially mounted on the bracket 4 with the motor 3, and the shaft 6 is inserted in the middle of the H-type bearing 5 and fixed on the square bar 7. The square bar 7 is fixed to the ground and the building wall with nails in the middle. Hoops 8 and 9 are installed on the upper and lower parts, one end of which is mounted on the sliding bracket and the other end is held on the fixed square bar. The hoop is made into an open ring so that it is not blocked by the fixing nails and can be flexible up and down and can fix the square bar. No matter how high the bracket is, there is no need to worry about the bracket loosening. The H-type bearing is made of many circular pieces. There are concave rings on both sides and then steel balls are installed in the concave. The center of it is also loaded with steel balls and then inserted into the shaft 6. Large-scale ones can have two identical groups that are symmetrical on the left and right.

Claims

1. The energy-efficient ropeless elevator uses the rotation of the screw to directly drive the bracket to rise and fall. The screw and the H-type bearing and the square bar are parallel to each other to increase the bite area. The screw and the motor shaft are installed on the sliding bracket.

2. Use many H-type bearings to replace the traditional rack to reduce resistance and wear. It is installed on the fixed square bar after the center is inserted into the shaft.

3. H-type bearings are composed of many discs, with many steel balls installed in the center and both sides of the discs. There are groove rings on both sides of the discs to accommodate the steel balls. There are steel balls in the center of the discs and on both sides, which means that ordinary bearings and pressed surface bearings are integrated.
