Description

Technical Field

[0001] This application belongs to the field of elevator stair surface anti-collision technology, and in particular relates to an elevator stair surface anti-collision mechanism. Background Technology

[0002] An elevator is a permanent transportation device that serves several specific floors within a building. Its car moves on at least two rigid tracks that are perpendicular to the horizontal plane or have an angle of inclination of less than 15° to the vertical. Elevators can be divided into passenger elevators and freight elevators. Freight elevators have a large load-bearing capacity, and staff often use trolleys to move goods in and out of freight elevators.

[0003] The existing utility model with authorization announcement number CN219602978U discloses an elevator anti-collision mechanism, including an anti-collision rod and an anti-collision rod base. The anti-collision rod base is fixedly installed at the bottom inside the elevator. The anti-collision rod base includes a first base and a second base. The first base is installed on one side inside the elevator, and the second base is installed on the other side inside the elevator. One end of the anti-collision rod is movably connected to the first base.

[0004] The above technical solutions can prevent mobile tools such as wheelbarrows from falling from heights due to accidental direct impact with the construction elevator door. However, most freight elevators only have a single anti-collision strip at the very bottom, which is not ideal. First, the existing anti-collision strips are not high enough to protect taller trolleys. Second, most existing anti-collision strips or anti-collision posts are made of rigid materials, and their anti-collision effect is achieved by hard impact, which can easily damage the goods. Such anti-collision mechanisms cannot meet the needs of most freight elevators.

[0005] Therefore, we propose an elevator stair surface anti-collision mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem that existing anti-collision mechanisms are ineffective or easily damage goods, and to propose an elevator stair surface anti-collision mechanism.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An elevator escalator anti-collision mechanism includes a car body. The car body has twelve mounting plates inside. A bent pipe is fixedly connected to one side of each set of mounting plates that are close to each other. A connecting pipe is fixedly connected to one side of each set of bent pipes that are close to each other. A flexible hose is installed inside each connecting pipe. A buffer layer is fixedly connected to the outer surface of each flexible hose. A wear-resistant layer is fixedly connected to the outer surface of each buffer layer. The outer surface of each wear-resistant layer is in contact with the inner wall of the connecting pipe. Five limiting brackets are engaged on the outer surface of each wear-resistant layer. A non-powered limiting telescopic rod is fixedly connected to one side of each set of limiting brackets that is far from each other. A strong spring is fixedly connected to the outer surface of each non-powered limiting telescopic rod. The far side of each set of non-powered limiting telescopic rods is fixedly connected to the inner wall of the car body.

[0009] Preferably, each of the mounting plates has six bolts on its outer side, and the end of each bolt near the mounting plate passes through the mounting plate and is threaded to the inner wall of the housing.

[0010] Preferably, the inner wall of each of the connecting pipes is threaded with a threaded rod, and the outer surface of each threaded rod is threaded with two threaded caps.

[0011] Preferably, a hoisting frame is provided on the outside of the chassis, and the inner wall of the hoisting frame is fixedly connected to the outer surface of the chassis.

[0012] Preferably, a chassis rail is provided on the outer side of the hoisting frame, and the inner wall of the chassis rail is slidably connected to the inner wall of the hoisting frame.

[0013] Preferably, a connector is provided above the hoisting frame, and the bottom surface of the connector is fixedly connected to the upper surface of the hoisting frame.

[0014] Preferably, five steel wire ropes are fixedly connected to the upper surface of the connector, and four sliding doors are slidably connected to the inner wall of the chassis.

[0015] Preferably, a buffer is fixedly connected to the upper surface of the chassis rail, and the buffer is located below the chassis.

[0016] In summary, the technical effects and advantages of this application are as follows:

[0017] By incorporating a mounting plate, bends, connecting pipes, a wear-resistant layer, a buffer layer, flexible hoses, a limit frame, a telescopic rod, and a powerful spring, the system effectively mitigates collisions. The mounting plate and bends, made of rigid materials, provide support, while the wear-resistant layer, buffer layer, and flexible hoses, made of soft materials, offer protection. The limit frame, telescopic rod, and powerful spring work together to buffer and support the impact, ensuring that when different trolleys come into contact with the anti-collision mechanism, the impact is effectively mitigated, protecting the goods on the trolleys.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 An elevator escalator anti-collision mechanism includes a car 1. The interior of the car 1 is provided with twelve mounting plates 2. Each mounting plate 2 has six bolts 11 on its outer side. The end of each bolt 11 near the mounting plate 2 passes through the mounting plate 2 and is threadedly connected to the inner wall of the car 1. The bolts 11 serve to fasten the mounting plates 2 and ensure the stability of the mounting plates 2.

[0025] Each set of mounting plates 2 has a bend 3 fixedly connected to one side of each other, and a connecting pipe 4 fixedly connected to one side of each set of bends 3. The inner wall of each connecting pipe 4 is threaded with a threaded rod 12, and the outer surface of each threaded rod 12 is threaded with two threaded caps 13. The cooperation between the threaded rod 12 and the threaded cap 13 serves to connect the connecting pipe 4 and the hose 7.

[0026] Each set of connecting pipes 4 has a flexible hose 7 inside, and a buffer layer 6 is fixedly connected to the outer surface of each flexible hose 7. A hoisting frame 15 is provided on the outside of each car 1. The inner wall of the hoisting frame 15 is fixedly connected to the outer surface of the car 1. The hoisting frame 15 is used to limit the movement trajectory of the car 1 and ensure the stability of the freight elevator during operation.

[0027] The outer surface of the buffer layer 6 is fixedly connected with a wear-resistant layer 5. The outer surface of each wear-resistant layer 5 is in contact with the inner wall of the connecting pipe 4. The outer side of the hoisting frame 15 is provided with a chassis rail 14. The inner wall of the chassis rail 14 is slidably connected with the inner wall of the hoisting frame 15. The hoisting frame 15 stabilizes the position of the chassis 1 and increases the overall strength of the chassis 1.

[0028] Five limit frames 8 are snapped onto the outer surface of each wear-resistant layer 5. A non-powered limit telescopic rod 9 is fixedly connected to the opposite side of each set of limit frames 8. A connector 16 is provided above the hoisting frame 15. The bottom surface of the connector 16 is fixedly connected to the upper surface of the hoisting frame 15. The connector 16 serves to connect the steel wire rope 17, ensuring that the connector 16 can lift the hoisting frame 15.

[0029] Each non-powered limit telescopic rod 9 has a strong spring 10 fixedly connected to its outer surface. The side of each set of non-powered limit telescopic rods 9 that is far apart from each other is fixedly connected to the inner wall of the machine compartment 1. Five steel wire ropes 17 are fixedly connected to the upper surface of the connector 16. Four sliding doors 18 are slidably connected to the inner wall of the machine compartment 1. The machine compartment 1 can be lifted up as a whole by using the steel wire ropes 17. The four sliding doors 18 are set up to achieve the purpose of bidirectional entry and exit, thereby improving the efficiency of handling goods.

[0030] A buffer 19 is fixedly connected to the upper surface of the chassis rail 14. The buffer 19 is located below the chassis 1. The buffer 19 is a safety device that can protect the safety of the staff inside the elevator in case of elevator malfunction.

[0031] The working principle of this utility model is as follows: When in use, the power provided by the externally installed motor first drives the steel wire rope 17 to rise or fall, so as to achieve the basic operation of the elevator. At this time, the design of four sliding doors 18 facilitates the entry and exit of staff. The cooperation of the car rail 14 and the hoisting frame 15 restricts the position of the car 1 and ensures the stability of the car 1.

[0032] When staff push the trolley into the elevator, the three-layer height design of the anti-collision mechanism can meet the height of most trolleys on the market, ensuring that most trolleys can contact the anti-collision mechanism. If the trolley comes into contact with the anti-collision mechanism, it will first contact the wear-resistant layer 5 and its internal buffer layer 6 and hose 7. The hose 7 is made of soft plastic and can bend freely under force. At this time, the hose 7 pushes the limit frame 8 to retract the non-powered limit telescopic rod 9. Then, the outward rebound force of the strong spring 10 can offset the impact force, thus achieving the goal of softly offsetting the impact force of the trolley, thereby protecting the goods on the trolley and avoiding the risk of damage to the goods from hard collisions.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
