Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a mining locomotive operating device. Background Technology

[0002] In mining production and transportation operations, electric locomotives are key equipment for transporting materials and personnel underground. To facilitate precise control of the locomotive by the driver in different positions, especially in specific working conditions such as vehicle coupling, dispatching, or limited visibility, portable or detachable operating devices are often used.

[0003] In practical applications, these portable operating devices need to be temporarily and securely mounted on the locomotive body during use. Existing fixing methods typically use bolts or clamps. However, while bolt fixing provides a reliable connection, its installation and disassembly process is cumbersome, requiring tools such as wrenches and is time-consuming, making it inefficient in situations where frequent relocation of the operating position is necessary. While clamps offer relatively convenient installation, the clamping force is often insufficient to guarantee the absolute stability of the operating device under the strong vibrations and impacts generated by the locomotive traveling underground, posing a risk of loosening or even detachment, which directly threatens operational safety.

[0004] Furthermore, the internal environment of mines is typically characterized by high levels of dust and moisture, which pose a serious threat to the delicate electronic components inside the operating devices, such as joysticks, switches, and circuit boards. Many existing operating devices are poorly designed to be waterproof and dustproof, making them susceptible to malfunctions such as poor contact and short circuits due to the intrusion of dust or moisture, thereby reducing the reliability and lifespan of the equipment.

[0005] Therefore, this utility model proposes a mining locomotive operating device to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a mining locomotive operating device, which aims to improve the problems of the existing mining locomotive operating devices, such as cumbersome fixed installation process, insufficient stability under strong vibration environment, and insufficient protection against harsh environments such as high dust and humidity in mines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A mining locomotive operating device includes: a cavity, an operating platform disposed on the cavity, a rocker arm disposed on the operating platform, and a fixing mechanism connected to the cavity; the fixing mechanism includes an mounting layer and a fixing plate; and a handle, an eccentric shaft, a squeezing block, and an expansion rod.

[0008] The eccentric shaft is mounted on the mounting layer, and the expansion rod passes through the fixing plate.

[0009] Furthermore, the handle is connected to the eccentric shaft, which drives the extrusion block to move. The extrusion block is slidably fitted inside the expansion rod and can expand the expansion rod, thereby fixing the entire device through the fixing plate.

[0010] Preferably, a shaft and bolt are provided between the eccentric shaft and the extrusion block, and the eccentric shaft pushes the extrusion block to move through the shaft and bolt.

[0011] Preferably, a rubber layer for buffering and wear resistance is provided between the eccentric shaft and the mounting layer.

[0012] Preferably, the outer side of the rocker arm is provided with a waterproof sleeve.

[0013] Preferably, the cavity is provided with an inspection door, the inspection door is equipped with a safety lock, and the inspection door is pivotally connected to the cavity via a hinge.

[0014] Preferably, the cavity is also provided with a waterproof connector for external electrical connection.

[0015] Preferably, the extrusion block has a wedge-shaped ramp that moves axially along the expansion rod to push the expansion rod.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting an expansion-type fixing mechanism consisting of a handle, an eccentric shaft, a squeezing block and an expansion rod, the operator only needs to rotate the handle to drive the squeezing block to open the expansion rod, which solves the problems of complex installation of the operating device in the prior art, reliance on tools and easy loosening in the strong vibration environment of the mine. It achieves the technical effect of fast and convenient installation, no tools required, firm and reliable fixing effect and strong seismic performance.

[0017] 2. In this utility model, by providing a waterproof sleeve for the rocker arm and a waterproof connector for external wiring on the cavity, and in conjunction with the closed cavity design, the problem of existing devices being easily damaged by dust and moisture in mines, resulting in low reliability, is solved. This achieves the technical effect of good waterproof and dustproof performance, strong environmental adaptability, and stable and reliable operation.

[0018] 3. In this utility model, by setting an inspection door on the cavity that is connected by a hinge and equipped with a safety lock, the problem of the existing device's internal structure being difficult to inspect and lacking safety protection measures is solved. This achieves the technical effect of facilitating maintenance and repair by professional personnel, preventing unauthorized personnel from misoperating, and improving the overall safety of the equipment.

[0019] 4. In this utility model, by setting a rubber layer between the eccentric shaft and the mounting layer inside the fixed mechanism, the problem of hard wear caused by long-term force rotation of key components in the transmission mechanism and the resulting impact on service life are solved. This achieves the technical effect of reducing mechanical wear, buffering impact force, and improving the durability and service life of the entire fixed mechanism. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to the appendix. Figure 1 -Appendix Figure 5 This utility model provides a mining locomotive operating device, which aims to solve the problems of complex fixing methods and insufficient stability under vibration environment of existing mining locomotive operating devices, as well as insufficient protection against harsh environments.

[0024] Specifically, the mining locomotive operating device includes a cavity 1 as the main body of the equipment, a fixing mechanism 2 for fixing the cavity 1 to the locomotive, and an operating platform 5 installed on the upper part of the cavity 1; the operating platform 5 is equipped with a rocker arm 4 for the operator to operate; the cavity 1 provides an installation base for other components and protects the internal components, and the fixing mechanism 2 is fixedly connected to the lower part of the cavity 1.

[0025] To achieve the aforementioned rapid and stable installation, the core of this mining locomotive operating device lies in the special design of the fixing mechanism 2. The fixing mechanism 2 mainly consists of a mounting layer 203, a fixing plate 10, a handle 201, an eccentric shaft 208, a shaft body 206, bolts 207, an extrusion block 205, an expansion rod 204, and a rubber layer 202. The mounting layer 203 is fixedly connected to the cavity 1 and serves as the mounting base for the internal transmission components of the fixing mechanism 2. The handle 201 is ergonomically positioned externally for easy application of rotational force by the operator. The eccentric shaft 208 is rotatably mounted on the mounting layer 203 and is connected to the handle 201. A rubber layer 202, providing cushioning and wear resistance, is also provided between the eccentric shaft 208 and the mounting layer 203. One end of the shaft body 206 is hinged to the eccentric portion of the eccentric shaft 208, and the bolts 207... The eccentric shaft 208 is connected to the other end of the shaft 206, so that the rotational motion of the eccentric shaft 208 can be converted into linear reciprocating motion through the shaft 206 and the bolt 207. The extrusion block 205 is slidably disposed above the bolt 207 and is moved by the push of the bolt 207. The extrusion block 205 has a wedge-shaped inclined surface. The expansion rod 204 passes through the fixed plate 10, and its inner cavity is slidably engaged with the extrusion block 205. When the operator rotates the handle 201 downward, the eccentric shaft 208 drives the shaft 206 and the bolt 207 to move upward. The bolt 207 pushes the extrusion block 205 to move axially along the expansion rod. The wedge-shaped inclined surface of the extrusion block 205 then spreads at least two halves of the expansion rod 204 outward, so that the expansion rod 204 expands radially and presses tightly against the inner wall of the mounting hole of the locomotive, thereby achieving a firm lock of the entire device through the fixed plate 10.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to improve the waterproof and dustproof performance of the device, a flexible waterproof sleeve 3 is provided on the outside of the rocker arm 4. The lower edge of the waterproof sleeve 3 is sealed and fitted to the operating table 5 to prevent liquid and dust from entering the cavity 1 along the gap at the root of the rocker arm 4. As another preferred embodiment, in order to facilitate the inspection and maintenance of the interior of the cavity 1 and ensure safety, an inspection port and an inspection door 6 are provided on the side wall of the cavity 1. The inspection door 6 is pivotally connected to the cavity 1 via a hinge 8. The inspection door 6 is also equipped with a safety lock 9 that requires a special key to open, to prevent unauthorized personnel from operating it by mistake. In another preferred embodiment, in order to ensure that the electrical connection between the device and the outside is safe and reliable in a humid environment, a waterproof connector 7 is provided at the bottom of the cavity 1, and the internal wiring terminals are sealed to the external cable through the waterproof connector 7.

[0027] Working principle: During installation, first insert the expansion rod 204 at the bottom of the fixing mechanism 2 into the preset mounting hole on the locomotive. Then, rotate the handle 201 downwards. The rotation of the handle 201 drives the eccentric shaft 208 to rotate. The eccentric shaft 208 converts the rotational motion into an upward linear thrust through the shaft body 206 and bolt 207. This thrust acts on the extrusion block 205, causing the extrusion block 205 to move upwards along the axial direction of the expansion rod 204. Because the extrusion block 205 has a wedge-shaped inclined surface, it will continuously push the expansion rod 204 outwards during its upward movement. This allows the device to expand radially and eventually press firmly against the inner wall of the mounting hole, thus achieving rapid and secure self-locking of the entire device. After fixing, the operator can control the locomotive via the rocker arm 4 on the control panel 5. The waterproof sleeve 3, inspection door 6, safety lock 9, and waterproof connector 7 work together to ensure the long-term stable and safe operation of the equipment in the humid and dusty environment of the mine. Through the above synergistic effect, this utility model effectively solves the problems of unstable fixing of the operating device, complex installation, and poor environmental adaptability in the prior art.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
