Technical Field

[0001] The utility model relates to the technical field of elevator protection structures, in particular to an elevator anti-overturning system. Background Art

[0002] Common lifting systems dedicated to cargo lifting and mechanical energy storage are mainly friction traction systems, such as common mining hoists. Such systems often have problems such as single safety measures and lack of anti-overturning structures. Civil elevators used for mixed passenger and cargo use have a lot of redundant designs to improve safety, resulting in high system costs and unable to meet the requirements of high-speed heavy-load freight and efficient transmission of mechanical energy storage systems. Therefore, especially in mechanical energy storage systems, there is an urgent need for an open elevator structure that can quickly move horizontally and pick up and place heavy objects, facilitate the free entry and exit of heavy objects in the elevator body, and prevent heavy objects from overturning when the elevator is in operation, thereby improving system safety. Utility Model Content

[0003] The utility model aims to provide an elevator anti-overturning system, which facilitates the free entry and exit of heavy objects into the elevator body and can prevent the heavy objects from overturning when the elevator is in lifting operation, thereby improving the safety of the system.

DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings, and this embodiment does not constitute a limitation of the utility model. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] An anti-overturning system for an elevator, such as Figure 1 and Figure 2 As shown, it is used in a mechanical energy storage system, including an electric generator 1 and an elevator body 2. The elevator body 2 is used to load a heavy object 31. When the electric generator 1 operates in motor mode, the elevator body 2 together with the heavy object 31 is lifted from a low position to a high position, and the electrical energy is converted into potential energy. On the contrary, when the electric generator 1 is in generator mode, the heavy object 31 drives the elevator body 2 to descend by its own gravity, and at the same time drives the traction shaft to rotate through the traction belt, and drives the electric generator 1 to rotate and generate electricity through the transmission system. This process converts the gravitational potential energy of the heavy object 31 into electrical energy. Its specific structural principle is the existing technology and will not be described in detail.

[0023] like Figure 2 As shown, a cargo inlet and outlet are provided on one side or on two opposite sides of the lift body 2, and an anti-overturning assembly 27 is provided at the cargo inlet and outlet position. The anti-overturning assembly 27 includes a blocking bar 2701 and an anti-overturning driving motor 2706 for driving the blocking bar 2701 to rotate. The rotation path of the blocking bar 2701 passes through a blocking position and an avoidance position. When the blocking bar 2701 rotates to the blocking position, it blocks the path of the cargo overturning or moving laterally in the direction of the corresponding inlet and outlet. When the blocking bar 2701 is transferred to the avoidance position, it leaves the path of the cargo moving laterally in the direction of the corresponding inlet and outlet.

[0024] In this embodiment, the elevator body 2 is only provided with one cargo entrance and exit, including a guide frame at the bottom and a transverse frame at the upper part. The guide frame is lifted and lowered under the guidance of traction and the vertical guide rail. The transverse frame is C-shaped, and the opening is the cargo entrance and exit. The open C-shaped structure is convenient for carrying heavy objects 31 whose width is greater than that of the transverse frame. The heavy objects 31 move laterally from the cargo entrance and exit to enter or leave the elevator body 2; relative lateral sliding with the guide frame is achieved through hydraulic means, and a hydraulic lifting system is arranged inside to facilitate the lateral movement of the heavy objects 31 in and out. The lifting and lowering of the heavy objects 31 are achieved through the lifting and lowering of the heavy objects 31, so as to realize the transportation of the heavy objects 31. That is, after the transverse frame moves laterally outward, the heavy objects 31 are lifted from the original platform by hydraulic lifting, and then the transverse frame is reset to realize the taking of the heavy objects 31, and vice versa.

[0025] like Figure 3 As shown, the anti-tipping assembly 27 includes two symmetrically arranged baffles 2701, which are respectively located on both sides of the corresponding cargo inlet and outlet, and the anti-tipping assembly 27 is installed on the top of the elevator body 2; when the baffles 2701 are rotated to the blocking position, they are set downward and blocked at the corresponding cargo inlet and outlet, and when the baffles 2701 are transferred to the avoidance position, they are set horizontally and point to the side close to each other.

[0026] like Figure 3 As shown, a circle of shaft retaining ring 2705 is provided on the rotating pin 2703, and a shaft bracket 2704 is fixedly connected to the top of the elevator body 2. The rotating pin 2703 passes through the shaft bracket 2704, and the shaft retaining ring 2705 abuts against the inner side of the shaft bracket 2704, which can prevent the rotating pin 2703 from being pulled out of the shaft bracket 2704. The outward thrust of the blocking bar 2701 can be transmitted to the shaft retaining ring 2705;

[0027] The outer end of the rotating pin 2703 is connected to the rotating seat 2702, and the baffle 2701 is detachably connected to the rotating seat 2702 by means of threads or the like, so as to facilitate the replacement of the baffle 2701, and the baffle 2701 is perpendicular to the rotating pin 2703. The anti-overturning drive motor 2706 is connected to and drives the rotating pin 2703 to rotate, thereby driving the rotating seat 2702 and the baffle 2701 installed thereon to rotate. The baffle 2701 is a long metal rod with a certain bending resistance.

[0028] When the elevator body 2 is loading or unloading a heavy object 31, the two baffle bars 2701 on the left and right sides are in a horizontal position, pointing inward; when the elevator body 2 is moving horizontally or lifting with a full load, the anti-overturning drive motor 2706 rotates to drive the baffle bars 2701 to rotate 90 degrees, and the lower half of the baffle bars 2701 on both sides are located in front of the upper edge of the heavy object 31. Once the heavy object 31 has a tilted displacement, the baffle bars 2701 can prevent the heavy object 31 from tilting further, thereby ensuring the safety of the system.

[0029] like Figure 3 and Figure 4 As shown, in order to further improve the stability of the elevator body during lifting and lowering and reduce the risk of overturning, a number of vertical guide rails 8 are installed in the elevator shaft, and a number of corresponding guide wheel systems 24 are connected to the bottom of the elevator body 2, and one set of guide wheel systems 24 is installed in conjunction with one vertical guide rail 8; the guide wheel system 24 includes two X-direction pressure wheels 241 and one Y-direction pressure wheel 242, the Y-direction pressure wheel 242 abuts against the side of the corresponding vertical guide rail 8 facing the elevator body 2, the X-direction pressure wheel 241 (x direction) is perpendicular to the Y-direction pressure wheel 242 (y direction), and abuts against the opposite sides of the vertical guide rail 8; in this embodiment, a total of 4 vertical guide rails 8 and 4 sets of guide wheel systems 24 are provided, which are respectively located in the front and rear directions on both sides of the elevator body 2, and the number of vertical guide rails 8 and guide wheels / guide wheel systems 24 can also be increased or decreased as needed.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions should also be deemed to fall within the protection scope of the technical solution of the present invention.
