A mechanical clamping device for an elevator car

Abstract

The invention relates to a mechanical clamping device used in an elevator car. The mechanical clamping device comprises a right-angled mounting plate and two clamping arms fixedly arranged on the mounting plate, wherein the mounting plate is of a right-angled structure, and the two clamping arms are arranged in a mirror symmetry mode; each clamping arm comprises a fixed arm fixedly arranged on the mounting plate, a clamping plate connected with the fixed arm through a telescopic transmission mechanism and a rubber base plate arranged on the clamping plate; and the clamping device is further provided with a motor speed reducing mechanism for driving the telescopic transmission mechanism and a wheel in-place detection device, wherein the motor speed reducing mechanism and the wheel in-place detection device are connected with a controller. The mechanical clamping device can be installed in the narrow elevator car; and by installing the device in the elevator car, a front wheel of a bicycle can be clamped and then lifted, and therefore an inclination state with the front wheel of the bicycle at a high position and a rear wheel touching the ground is formed, the space of the elevator car in the height direction can be well utilized, and the length of the bicycle does not divide the space of the elevator car into two portions.

Description

technical field [0001] The invention relates to a mechanical clamping device for an elevator car, in particular to a lifting device which is conveniently installed in the elevator car and can clamp the front wheel of a bicycle. Background technique [0002] In urban life, many people live in high-rise residential buildings, and high-rise residential buildings must rely on van elevators to go up and down. Since most people's commuting time is the same, there will be a peak in the morning and afternoon of weekdays. Expect. In the plain cities in the north, many people rely on bicycles to commute to get off work. Using bicycles to travel is a green and environmentally friendly way, which is very convenient and saves money. Therefore, many people insist on using bicycles to travel. [0003] There are many types of bicycles. Among them, 26-inch and 27-inch mountain bikes and road racing bikes are the two most common types. The lowest price is about 1,000 yuan, and the slightly b...

Problems solved by technology

[0004] The length of 26-inch and 27-inch mountain bikes and road racing cars is more than 1700mm. However, the size of the elevator car in the house is relatively small. Even if the car is larger, its length or width will not reach 170cm. , especially in many communities with high residential density and a large number of floors, the elevator car size is 1300*1300mm, and the diagonal length is only 1800mm. For example, in some affordable housing communities supervised by the government , Eighteen households on each floor, equipped with five elevators, three of which are normally open and two for backup, and the size of the elevator car is 1300*1300mm. There are many residents and the elevator space is small. In this case, the elevator car with a length of 1700mm When the bicycle is put into the elevator car, it can only use the length space of the diagonal line of the car. In this way, the bicycle divides the space of the elevator car into two parts from the position of the diagonal line, such as figure 1 As shown, even if the front wheel and the handlebar are twisted 90 degrees, and the length of the handlebar is added, the length reaches about 1500mm. One side of the elevator car must not be able to accommodate, and the space of the elevator car is still divided into two parts. Partly, in this case, the passengers that the elevator can accommodate will be seriously affected, greatly reducing the carrying capacity of the elevator, resulting in a large number of people waiting anxiously for the elevator in the morning and evening peak hours, resulting in "congestion" and "low efficiency" Phenomenon

[0005] Especially in the morning rush hour, people with lower floors will take the elevator up, and people on each floor will press the two buttons "up" and "down" at the same time. Since the elevator is separated by bicycles, part of the space cannot be used, so there is no It will be fully loaded, which will cause the elevator to stop floor by floor, but it cannot carry people or cars, and the efficiency is extremely low. In severe cases, it takes 20 minutes to go down the stairs, which is unbearable for many people.

[0006] In order to solve the above-mentioned technical problems, the applicant believes that it is possible to develop a sticking lifting mechanism, which clamps the front wheel of the bicycle and lifts it upwards. By using the upper space in the elevator car, the space on the bottom surface of the elevator car is freed to prevent the bicycle from falling. The elevator car is divided into two parts, resulting in the problem that one of the corners cannot be fully utilized

However, due to the limited space in the elevator car, the installation of the clamping and lifting device requires a certain power source. Therefore, on the basis of installing the clamping and lifting mechanism in the elevator car, it is necessary to further consider the installation position and the volume of the entire device. And technical issues such as the acquisition of power sources
