Preferably, a buffer seat facing the counterweight is provided on the bottom side of the hoistway.

Preferably, the section of the hoistway is square, and the section of the car is octagonal with four corners cut off.

Preferably, the hoistway has multiple layers, and the four sides of the hoistway on each layer are provided with landing doors corresponding to the car doors.

Preferably, the hoistway has two layers, the shaft has a first layer and a second layer, and the four sides of the first layer and the second layer are respectively provided with four landing doors.

Preferably, the four sides of the car are respectively provided with door operators for driving the car door.

Preferably, the hoistway includes a hoistway main body, the car includes a car main body, and the hoistway main body and the car main body are equipped with transparent glass panels.

With respect to the above-mentioned background technology, the elevator with doors open from all sides provided by the present invention includes a shaft and a car installed in the shaft. There are two sets of diagonals inside. The first set of diagonals is provided with a pair of guide rail brackets, each of which is provided with a guide rail. The second set of diagonals is arranged with a car frame for carrying the car. There is a car fixing frame sliding along the guide rail on the side. The four-sided door elevator realizes four-sided door opening by setting car doors on different four sides of the car, and realizes the up and down movement of the car in the hoistway by setting the traction machine. Guide rail brackets are used to fix the guide rails. By setting the guide rails and the car fixing frame matched with the guide rails, the car can rise or fall along the rails in the hoistway. During the use of the four-sided door elevator, the four car doors can be opened at the same time. For users to transfer in and out, the number of passengers entering the elevator increases, which effectively solves the problem of congestion at the elevator door, saves the time for transferring elevators, improves social and economic benefits, and also cleverly utilizes the hoistway. Two sets of diagonals make reasonable use of the well space. This elevator with doors opening from all sides is suitable for special buildings.

The heavy rope ends form a "loop" fixed at both ends, and the car 5 and the counterweight 7 run up and down in the hoistway to serve each floor.

Exemplarily, the number of car bottom wheels 6 is two. In this embodiment, the steel belt 12 starts from the car rope head, passes through two car bottom wheels 6 in turn, and then reaches the steel belt main machine, and finally bypasses the counterweight 7 Reach the end of the counterweight rope and form a "loop" with both ends secured.

In addition, a buffer seat 8 is provided on the bottom side of the hoistway, and the buffer seat 8 is located directly below the counterweight 7 and is arranged towards the counterweight 7 so as to play the role of buffering and shock absorbing.

Exemplarily, the outer cross-section of the hoistway is square, and the cross-section of the car 5 is an octagon with four corners cut off, wherein, the inner cross-section of the hoistway matches the cross-section of the car 5 with an inner hollow octagon.

In this embodiment, the hoistway has multiple layers. In other words, the four-sided door elevator is provided with multiple layers to meet the needs of people carrying in buildings of different heights. The landing doors 10 are installed on the four openings on the four sides of the hoistway through the door pockets 9, the number of landing doors 10 in each well is four, and the four sides of the car 5 are respectively provided with the opening and closing of the car door 11. Door operator, considering door operator and guide rail support 14 can not have interference, so guide rail support 14 will special design, promptly make a small rectangular structure, and strength is better.

Exemplarily, the hoistway has two floors, the car 5 travels between the first floor of the hoistway and the second floor of the hoistway, and four landing doors 10 are respectively provided on the four sides of the first floor and the second floor.

In another specific embodiment, the hoistway includes a hoistway main body, and the car 5 includes a car main body, and the hoistway main body and the car main body are equipped with transparent glass panels. In the novel four-sided sightseeing elevator, the shaft and the car 5 are made of transparent glass, such as landing doors 10 and car doors 11, to meet the needs of natural light transmission and sightseeing.
