Abstract
Description
Technical Field
[0001] This utility model relates to the field of ladder technology, specifically a mine safety ladder. Background Technology
[0002] A ladder is a facility that facilitates movement at different heights within a mine. Ladders are usually fixed inside the mine shaft. Given the narrow cross-section of the shaft, when a disaster occurs underground, miners need to escape the disaster area by climbing the ladder. However, miners also need to use safety belts and hooks on the safety belts to hang on the ladder to prevent them from falling off during the climb. During the climb, the position of the hooks needs to be changed frequently, which seriously affects the escape time of the miners. Therefore, in order to solve the above technical problems, this utility model provides a mine safety ladder. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a mine safety ladder.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a mine safety ladder, comprising a ladder, wherein multiple railings are fixedly installed at equal intervals along the length of the ladder, safety rods are fixedly installed on the railings via connecting blocks, a sliding sleeve is slidably installed on the outer surface of the safety rod, a channel plate is fixedly installed on the outer surface of the sliding sleeve, an installation block is fixedly installed on the outer surface of the channel plate, a rope is fixedly installed on the installation block, and a notch is provided on the sliding sleeve;
[0005] A rotating block is rotatably mounted on the outer surface of the safety bar, a blocking block is fixedly mounted on the safety bar and located on the lower surface of the rotating block, and a limiting block is fixedly mounted at the bottom end of the channel plate.
[0006] Preferably, a ball bearing is rotatably mounted on the sliding sleeve, and a slide rail is provided on the outer surface of the safety bar for the ball bearing to slide.
[0007] Preferably, a plurality of the fences are fixedly installed with reinforcing bars between them. Beneficial effects
[0008] Compared with the prior art, this utility model provides a mine safety ladder with the following advantages:
[0009] A safety bar is fixedly installed on the fence via connecting blocks. A sliding sleeve is slidably installed on the outer surface of the safety bar. A passage plate is fixedly installed on the outer surface of the sliding sleeve. A rope is fixedly installed on the outer surface of the passage plate. A rotating block is rotatably installed on the outer surface of the safety bar. A blocking block is fixedly installed on the safety bar and located on the lower surface of the rotating block. A limiting block is fixedly installed at the bottom of the passage plate. This reduces the difficulty for personnel to climb upwards in the mine, making it faster and more convenient to climb upwards and escape.
[0010] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. The specific implementation methods of this utility model are given in detail in the following embodiments and their accompanying drawings. Attached Figure Description

[0017] The following combination Figures 1 to 4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0018] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0020] Please combine Figures 1 to 4 As shown, this utility model provides a mine safety ladder, which has a ladder 1. Multiple railings 3 are fixedly installed at equal intervals along the length of the ladder 1. The multiple railings 3 are fixedly connected by reinforcing rods 4 to increase the strength of the multiple railings 3. Safety rods 5 are fixedly installed on the railings 3 by connecting blocks 2. Sliding sleeves 8 are slidably installed on the outer surface of the safety rods 5. Ball bearings 10 are rotatably installed on the inner surface of the sliding sleeves 8. A slide rail 11 for the ball bearings 10 to slide is opened on the outer surface of the safety rods 5. A channel plate 9 is fixedly installed on the outer surface of the sliding sleeves 8. An installation block 13 is fixedly installed on the outer surface of the channel plate 9. A rope 14 is fixedly installed on the installation block 13. A notch 15 is opened on the sliding sleeves 8, which is adapted to the connecting block 2.
[0021] A rotating block 6 is rotatably mounted on the outer surface of the safety bar 5, a blocking block 7 is fixedly mounted on the safety bar 5 and located on the lower surface of the rotating block 6, and a limiting block 12 is fixedly mounted at the bottom of the channel plate 9.
[0022] In case of emergency, the safety belts worn by the personnel underground are fixedly connected to the rope 14. During the upward climbing process, the top of the passage plate 9 contacts the lower surface of the rotating block 6, which can push the rotating block 6 to rotate upward, allowing the passage plate 9 to pass over the rotating block 6 smoothly. If the climber accidentally separates from the ladder 1, the sliding sleeve 8 slides downward, and the limiting block 12 on the passage plate 9 will contact the upper surface of the rotating block 6. Due to the obstruction of the blocking block 7, the sliding sleeve 8 cannot slide downward smoothly, preventing the climber from falling. During the climbing process, the sliding sleeve 8 can rise smoothly with the climber without the climber needing to change the position of the sliding sleeve 8, making the upward climbing escape faster and more convenient.
[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
