Description

Technical Field

[0001] The utility model relates to the technical field of inclined shaft layout, in particular to a safety detection yard layout device for preventing car dropping at the inclined shaft wellhead. Background Art

[0002] In the layout of the traditional inclined shaft wellhead yard in mines, a horizontal yard layout is mostly adopted. Although this layout form is simple, there are significant potential safety hazards in actual operation. Especially when uncoupling and coupling operations are carried out between ore car groups, due to factors such as complex working environments, insufficient light, or worker fatigue in mines, it is extremely easy to be negligent, resulting in the failure to correctly connect the couplings between ore cars. When the winch starts to lower the ore car group, the ore cars that are not firmly connected may suddenly fall off, causing serious safety accidents, not only threatening the lives of workers but also possibly damaging the mine equipment and affecting the production progress. In addition, the traditional horizontal yard layout also lacks an effective detection mechanism during the lowering process of the ore car group, and it is unable to detect and correct the situation where the couplings are not properly hung in a timely manner, further increasing the risk of car dropping accidents. In view of this, this application is specifically proposed. Content of the Utility Model

[0018] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0019] Please refer to the attached Figure 1-2 , an anti-falling vehicle safety detection yard 4 layout device at the inclined shaft wellhead, including a hoist chamber 1, an inclined shaft roadway, a yard 4, a slope 5, and a second ramp 6. The inclined shaft roadway is arranged between the hoist chamber 1 and the second ramp 6. The slope 5 is arranged between the inclined shaft roadway and the yard 4. An included angle of 6 degrees is formed between the slope 5 and the yard 4. The height of the inclined shaft roadway is higher than that of the yard 4. The second ramp 6 is connected to the inclined shaft entrance, and an included angle of 24° is formed between the second ramp 6 and the inclined shaft wellhead.

[0020] In some embodiments, the inclined shaft roadway includes a first ramp 3 and a platform 2. The first ramp 3, the platform 2, and the hoist chamber 1 are connected in sequence. An included angle of 6 degrees is formed between the first ramp 3 and the platform 2. The height of the first ramp 3 is higher than that of the platform 2. The slope 5 is connected to the break point between the first ramp 3 and the platform 2.

[0021] Adopting the above technical solution, the first ramp 3 is located between the hoist chamber 1 and the platform 2, forming a first ramp 3 with an included angle of 6 degrees for the preliminary guidance of the ore car group during the lowering process. The slope 5 is arranged between the platform 2 and the yard 4, and an included angle of 6 degrees is formed between the slope 5 and the yard 4, further helping the ore car group to move smoothly during the hook detection. If the hook is not properly hung, the ore car will not be lifted upward along with the hoisting steel wire rope, and the worker can continue to hang the hook of the ore car and then repeat the previous step. If the hook has been properly hung, the hoisting winch will continue to lift it to the platform 2, and then the ore car group will be lowered by the self-weight of the ore car group and the pulling force of the winch. The yard 4 serves as the parking and hooking area for the ore car group;

[0022] The second ramp 6 connects the platform 2 and the inclined shaft entrance, forming an included angle of 24°, which is the main channel for the lowering of the ore car group. A lowering device 7 is arranged in the hoist chamber 1 to control the hoisting and lowering of the ore car group through the first ramp 3, the platform 2, and the second ramp 6;

[0023] An included angle of 6 degrees is formed between the platform 2 and the first ramp 3. The height of the first ramp 3 is higher than that of the platform 2. The first ramp 3 with an included angle of 6 degrees can enable the ore car group to slide down according to its own gravity, enabling the ore car group to obtain a certain downward gravity component, which is convenient for the staff to push the ore car group.

[0024] In some embodiments, a lowering device 7 is provided on the hoist chamber 1, and the lowering device 7 passes through the first ramp 3, the platform 2, and the second ramp 6.

[0025] It should be noted that the lowering device 7 is composed of components such as a hoist, a steel rope, and a guide wheel. The entire lowering device 7 is an existing technology and will not be elaborated here.

[0026] In some embodiments, an upper and lower station platform is provided on the platform 2. The upper and lower station platform provides a safe area for workers during operation, facilitating the observation and operation of the coupling of the mine car group and the hoisting process.

[0027] Working principle:

[0028] In the initial state, the mine car group is parked in the yard 4, waiting for coupling. There is a slightly inclined ramp 5 designed between the yard 4 and the inclined shaft roadway. Workers perform coupling operations on the mine car group in the yard 4 to ensure the firm connection between each mine car, and then start to detect the coupling. The winch is used to drive the coupled mine car group towards the ramp 5. Since the ramp 5 slopes upward from the yard 4 towards the platform 2, during this process, if the coupling is not properly done, the mine car group will not be able to rise along with the hoisting steel wire rope and will remain in place or slide slightly downward, thus achieving the effect of reminding workers to recheck, so that the workers can hang the coupling properly after inspection;

[0029] After confirming that the coupling is correct, the winch continues to hoist to the inclined shaft roadway, enabling the lowering device 7 to be connected to the mine car group. Since an angle of 6 degrees is formed between the platform 2 and the first ramp 3, and the height of the first ramp 3 is higher than that of the platform 2, by using the self-weight of the mine car group, under the action of gravity, the mine car group slides down along the first ramp 3 to the platform 2. The setting of the first ramp 3 can save the effort of workers to push the mine car group. Then, the lowering device 7 drives the mine car group to be lowered along the ramp 5, and the mine car group is lowered along the inclined shaft to the designated position.

[0030] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention.
