Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 This embodiment provides a semi-automatic lifting and early warning device for an open-pit coal mine production command vehicle, including a vehicle mechanism 100, a lifting mechanism 200, and a warning mechanism 300.

[0020] Reference Figure 1 The vehicle mechanism 100 includes a front drive component 101 and a rear cargo box component 102 connected thereto. The front drive component 101 is equipped with a vehicle body, and the interior of the vehicle body includes an engine, a control panel, and a seat, which can be used by staff to ride or drive the vehicle. The rear cargo box component 102 consists of a hollow rear cargo box body and rear moving wheels, which facilitates the carrying of the lifting mechanism 200 and the warning mechanism 300.

[0021] Reference Figure 1 , Figure 2 , Figure 3The lifting mechanism 200 includes a base 201, which is an elliptical, hollow shell. One side of the base 201 is connected to a wire, a command receiver, and a controller. The upper end of the base 201 has two sets of circular grooves that fit the bottom of the fixing rod 204 and the protective cylinder 203. A first threaded post 202, threaded into the interior of the rear cargo box component 102 and corresponding to the bottom of the base 201, is also threaded. Half of the first threaded post 202 is installed inside the lower end of the base 201, and the other half is embedded inside the rear cargo box 102. The installation method can vary depending on the specific situation and is not limited to one set of first threaded posts. The upper end of the base 201 is bolted to the column 202 and the base 201, and a fixing rod 204 is bolted to the fixing rod 204. The fixing rod 204 is a cylindrical rod with an internal diameter larger than that of the lifting rod 205, and can just accommodate the space of the limiting plate 204a. The fixing rod 204 is equipped with a lead screw 205b. The top of the lead screw 205b is equipped with a lifting rod 205 that runs along a spiral line. The lifting rod 205 is hollow inside with a screw groove, which can mesh with the lead screw 205b. The lifting rod 205 moves telescopically on the lead screw 205b. The top of the lifting rod 205 is provided with a first threaded groove 205a.

[0022] Reference Figure 1 , Figure 2 , Figure 5 The warning mechanism 300 is connected to the trapezoidal connecting sleeve 305 at the top of the lifting rod 205, and the supporting arc plate 304 is connected to the upper end of the trapezoidal connecting sleeve 305. A photosensitive component 306 is provided at the end of the supporting arc plate 304 away from the trapezoidal connecting sleeve 305. Threaded grooves are provided at both the upper and lower ends of the trapezoidal connecting sleeve 305 to facilitate the docking of the upper and lower components. A hydraulic cylinder 308 is sealed to the upper end of the supporting arc plate 304. The hydraulic cylinder 308 includes a shell, a gas compression component and a sealing ring.

[0023] Example 2 This embodiment is based on the previous embodiment, but differs from it in that: in this embodiment, during open-pit coal mine production, workers driving a command vehicle can automatically raise or lower the early warning device. The specific structure of this embodiment is as follows.

[0024] refer to Figure 4 The fixed rod 204 is hollow inside and has a limiting disc at the top. The lifting rod 205 passes through the limiting disc. The inner wall of the fixed rod 204 is provided with a limiting plate 204a. The limiting plate 204a is hollow inside and can accommodate the wire connected to the micro switch 204a-1. The length of the limiting plate 204a is less than the length of the inner wall of the fixed rod 204. Two sets of micro switches 204a-1 are provided on one side of the limiting plate 204a, and the brake buttons of the two sets of micro switches 204a-1 are installed on the inside.

[0025] Combination Figure 3 , Figure 4Limiting rings 205c are attached to both sides of the limiting plate 204a. One end of the limiting ring 205c has a groove of the same width as the limiting plate 204a, allowing the limiting plate 204a to slide on the limiting ring 205c. The limiting ring 205c is fixed inside to the outer wall of the lifting rod 205 and is located at the end of the lifting rod 205. The top of the lifting rod 205 can pass through the top limiting disc of the fixed rod 204. When the lifting rod 205 is rotated by the lead screw 205b, it will be limited by the limiting ring 205c, so the lifting rod 205 cannot rotate and can only move slowly upward. When the limiting ring 205c contacts the micro switch 204a-1, the lifting rod 205 stops moving.

[0026] refer to Figure 4 The bottom of the lead screw 205b is provided with a secondary gear 205b-1, and a first connecting rod 201a and a second connecting rod 201b are fixed inside the base 201 in sequence. A first reduction gear 201a-1 and a second reduction gear 201b-1 are respectively sleeved on the ends of the first connecting rod 201a and the second connecting rod 201b. The first reduction gear 201a-1 and the second reduction gear 201b-1 are the same size and mesh with each other. The secondary gear 205b-1 and the first reduction gear 201a-1 mesh with each other, and the first reduction gear 201a-1 and the second reduction gear 201b-1 mesh with each other.

[0027] refer to Figure 2 , Figure 3 and Figure 4 A protective cylinder 203 is provided on the upper end of the base 201 away from the fixed rod 204. The protective cylinder 203 is parallel to the fixed rod 204. A brushless motor 203a is sleeved inside the protective cylinder 203, and the output end of the brushless motor 203a faces downward.

[0028] refer to Figure 4 The lower end of the brushless motor 203a is fitted with a connecting shaft 203a-1, the top end of the connecting shaft 203a-1 is fixed on the output end, and the corresponding end of the connecting shaft 203a-1 is fitted with a main gear 203a-2, which meshes with the second reduction gear 201b-1.

[0029] In this embodiment, when overall lifting is required, the controller first controls the command receiver to start the brushless motor 203a inside the protective cylinder 203 to rotate. While the brushless motor 203a rotates, it drives the main gear 203a-2 below to rotate. The movement of the main gear 203a-2 drives the first reduction gear 201a-1 and the second reduction gear 201b-1, which in turn drives the auxiliary gear 205b-1. The rotation of the auxiliary gear 205b-1 drives the lead screw 205b to rotate, so that the lifting rod 205 connected to the lead screw 205b is driven by the lead screw 205b to repeatedly extend and retract up and down, thereby achieving the adjustment of the overall height.

[0030] Example 3 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: this embodiment includes a lifting mechanism 200 that can extend and retract while simultaneously enabling the warning mechanism 300 to issue an early warning. The specific structure of this embodiment is as follows.

[0031] Combination Figure 2 and 6 A spring wire 307 is fixedly and electrically connected to the lower end of the support arc plate 304 near the side of the photosensitive component 306. The photosensitive component 306 includes a photosensitive module and an infrared photosensitive component. A sealing ring 311 is wrapped around the upper end of the hydraulic cylinder 308, and the other end of the sealing ring 311 is wrapped around the lamp tube 301. The lamp tube 301 is hollow, and there are three sets of lamp tubes 301. Each set of lamp tubes 301 is connected by a sealing ring 311.

[0032] refer to Figure 6 A hydraulic tank 309 is fixedly installed inside the lamp tube 301. The input end of the lower end of the hydraulic tank 309 is connected to the output end of the hydraulic cylinder 308. Hydraulic plates 309a are provided at both ends of the hydraulic tank 309. The hydraulic plates 309a include a support plate and a flexible hydraulic layer, which facilitates closing and opening. The two sets of hydraulic plates 309a extend and retract in opposite directions.

[0033] refer to Figure 6 A support column 310 is fixedly installed on the left side of the hydraulic plate 309a. A telescopic column 310b is sleeved on the left side of the support column 310. A spring cylinder 310a is wound around the outer wall of the telescopic column 310b. The telescopic column 310b and the support column 310 are separated by a partition. The support column 310 passes through the partition. One end of the spring cylinder 310a is attached to the left side of the partition, and the other end is attached to the inner side of the lamp tube 301.

[0034] Combination Figure 2 and 6An arc-shaped light panel 302 is fixedly installed on the left side of the telescopic column 310b. The arc-shaped light panel 302 emits three colors of light, and each group of lamp tubes 301 corresponds to a different light source, namely red, blue, and orange. The arc-shaped light panel 302 is attached to the outer wall of the lamp tube 301 and is exactly half of the outer wall of the lamp tube 301. A supplementary light plate 312 is fixedly installed on the outer wall of the lamp tube 301. A buzzer 303 is sealed and connected to the upper end of the lamp tube 301.

[0035] In this embodiment, when a warning is required, the photosensitive component 306 automatically controls the arc-shaped lamp plate 302 on the outside of the lamp tube 301 to light up when it senses that the ambient light has dimmed, thus forming a warning. When there is rain, snow, or fog in the external environment, the controller can control the hydraulic cylinder 308 to work. The hydraulic cylinder 308 draws air inward, causing the gas to be pumped to both sides in the hydraulic tank 309, which drives the support column 310 to open outward, while simultaneously compressing the telescopic column 310b to extend and retract outward. This causes the curved light panel 302 to move away from the lamp tube 301. When the curved light panel 302 moves away from the lamp tube 301, the visual distance between the staff and the curved light panel 302 will be shortened. At this time, the light emitted by the curved light panel 302 that is away from the lamp tube 301 will be greater than the light emitted by the curved light panel 302 that is not away from the lamp tube 301. Furthermore, the warning light can be enhanced by the supplementary light plate 312 on the outer wall of the lamp tube 301, thus strengthening the warning and preventing the staff from being unable to see the light and causing harm.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
