Description

Technical Field

[0001] This utility model relates to the field of railcar technology, specifically to a railcar cab. Background Technology

[0002] Currently, the installation and maintenance of traditional railcar cabs used in underground coal mines present numerous inconveniences. Traditional railcar cabs and chassis mounting panels are typically rigidly connected using multiple sets of bolts. Installation requires multiple workers to work together to tighten each bolt individually, which is not only time-consuming and labor-intensive, but also further prolongs installation time due to limited tool access in the confined underground space. When the cab needs repair or replacement, disassembling the bolts is equally cumbersome, often requiring significant manpower and time, severely impacting the operational efficiency of the railcar. Furthermore, traditional cabs mostly lack dedicated lifting structures, making them prone to center of gravity shifts during lifting and transportation, increasing lifting difficulty and safety risks. This poses a significant challenge to the disassembly, assembly, and maintenance of the cab, especially in the complex underground working environment.

[0003] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

The control panel 3 is made of ABS engineering plastic with a non-slip textured surface. It integrates multiple function buttons and knobs on the front. A dedicated control switch is provided for the electric push rod 22. This control switch is a two-way self-resetting switch. Pressing one end of the switch controls the electric push rod 22 to extend and push the insert 23 into the perforated steel column 21 for fixation. Pressing the other end of the switch controls the electric push rod 22 to retract, causing the insert 23 to disengage from the perforated steel column 21, facilitating the separation of the cab body 1 from the mounting panel 19. The control handle 4 is ergonomically designed for comfortable grip. It integrates a displacement sensor and is connected to the railcar's driving control system via a wire. The driver and passengers can control the railcar's forward, backward, steering, and speed operations through the control handle 4. Storage box 14 is made of polypropylene, which has a certain degree of impact resistance and corrosion resistance. It has internal dividers to classify and store items, making it convenient for drivers and passengers to place tools, documents and other personal items.

[0028] Example 5 refer to Figure 4 and Figure 5 A brake handle 15 is installed on the lower inner side of the cab body 1, and the brake handle 15 is located on the right side of the seat 2.

[0029] A brake handle 15 is installed on the lower inner side of the cab body 1, near the right side of the seat 2. The brake handle 15 is made of cast steel with a powder-coated surface to prevent rust. The brake handle 15 is connected to the railcar's braking system via a pivot shaft. A return spring is installed at the pivot shaft, allowing the brake handle 15 to automatically return to its initial position when the driver or passenger releases it. A brake travel switch is installed below the brake handle 15. When the driver or passenger pulls the brake handle 15, the brake travel switch is triggered simultaneously, transmitting a braking signal to the railcar's main controller. Upon receiving the signal, the main controller controls the braking actuators to decelerate or stop the railcar. The brake handle 15 has moderate operating force and a reasonable travel, facilitating quick and accurate braking by the driver or passenger, ensuring the railcar's safe operation.

[0030] Example 6 refer to Figure 6 The perforated steel column 21 has a square hole on its surface corresponding to the insertion block 23. The head of the insertion block 23 has a conical structure. A pin 25 is inserted and installed on the side of the perforated steel column 21, and the pin 25 is inserted into the insertion block 23.

[0031] The perforated steel column 21 has a square hole on its surface corresponding to the insertion block 23. The size of the square hole matches the cross-sectional size of the insertion block 23, with the gap controlled within 0.5mm to ensure a firm connection after insertion. The head of the insertion block 23 has a conical structure with a conical angle of 30 degrees. This conical structure guides the insertion block 23 when it is inserted into the square hole of the perforated steel column 21, facilitating quick and accurate insertion. A cylindrical pin 25, made of stainless steel, is inserted and installed on the side of the perforated steel column 21 below the square hole. One end of the pin 25 has a pull ring for easy insertion and removal. The corresponding position of the insert 23 is provided with a pin hole that matches the pin 25. When the insert 23 is fully inserted into the perforated steel column 21, the pin 25 can pass through the side wall of the perforated steel column 21 and be inserted into the pin hole of the insert 23 to form a double fixing structure. This prevents the insert 23 from accidentally coming out when the electric push rod 22 fails, and further improves the reliability of the connection between the cab body 1 and the mounting panel 19.

[0032] Example 7 refer to Figure 5 and Figure 6 The upper part of the back of the cab body 1 is equipped with a remote control receiver 16, an audible and visual alarm 17 and a methane sensor 18, which are arranged in a linear fashion.

[0033] The upper rear of the cab body 1 is equipped with a remote control receiver 16, an audible and visual alarm 17, and a methane sensor 18, all arranged linearly on the same horizontal line with a spacing of 20cm. The remote control receiver 16, model XY-RF-02, operates at a frequency of 433MHz and receives control signals from the remote controller, transmitting these signals to the main controller of the railcar to enable remote control of the railcar. The audible and visual alarm 17, model LTE-1101J, features both audible and visual alarm functions. The audible alarm volume reaches 110 decibels, and the visual alarm uses a red strobe light. When the railcar malfunctions or encounters an emergency, the main controller will trigger the audible and visual alarm 17 to alert surrounding personnel to safety. The methane sensor 18 is model MQ-4, with a detection range of 0-100%LEL. It can detect the concentration of methane gas in the environment around the cab in real time and convert the detected concentration signal into an electrical signal and transmit it to the main controller. When the methane concentration exceeds the set threshold, the main controller will immediately trigger the audible and visual alarm 17 and cut off the power supply of the railcar to prevent safety accidents.

[0034] Working principle: First, the cab is hoisted onto the mounting panel 19 using the lifting ring 8 on the top surface of the cab body 1, aligning the perforated steel columns 21 in the four corner shock absorbers 9 with the mounting frame 20 on the mounting panel 19 and extending them inwards. The control switch on the control panel 3 on the right side of the operating seat 2, corresponding to the electric push rod 22, extends the electric push rod 22, pushing the insert 23 through the square hole in the perforated steel column 21 and inserting it into the positioning sleeve 24 on the inner side of the mounting frame 20, completing the initial fixation between the cab and the mounting panel 19. Then, the pin 25 is inserted for double fixation. During driving, the laser radar 10 inside the explosion-proof protective shell 7 on the top of the cab body 1 scans for obstacles in real time, and the camera 12 captures real-time images of the front. Both data are transmitted via shielded wires to the screen 13 in front of the seat 2 for display. The headlights 11 adjust the high and low beams according to the ambient light to provide illumination for driving. The operator controls the railcar's forward, reverse, steering, and speed via the operating handle 4, and decelerates or stops via the brake handle 15. The braking signal is transmitted to the main controller via the brake limit switch to control the braking actuators. Simultaneously, the methane sensor 18 on the back of the cab monitors the methane concentration in real time, and the remote control receiver 16 receives remote control signals. When a malfunction occurs or the methane concentration exceeds the standard, the main controller triggers the audible and visual alarm 17 to ensure operational safety.
