Description

Technical Field

[0001] This utility model belongs to the technical field of mining transport vehicle cab design, specifically relating to a mining transport vehicle cab structure. Background Technology

[0002] Currently, mining truck cabs come in two structures: simple support and fully enclosed. Simple support cabs consist only of a cab roof and four supporting columns. While offering good visibility and ventilation, drivers often operate in a semi-reclining position, resulting in poor comfort. Furthermore, simple support cabs often pose significant safety hazards underground, such as falling objects, flying debris, and intrusion of underground anchor cables and support netting into the cab, all of which severely threaten the driver's life. Fully enclosed cabs, on the other hand, make it difficult for drivers to escape when turning underground or when the doors cannot be opened due to vehicle malfunction. They also significantly hinder communication between the driver and the outside world.

[0003] Therefore, how to design a new type of transport vehicle cab structure to solve the technical problems of safety, comfort, and difficulty in communication between the driver and the outside world in the cabs of existing coal mine transport equipment has long troubled technicians in this field. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cab structure for a mining transport vehicle. This structure adopts an integrated modular design and a fully enclosed structure, which can solve the technical problems of safety, comfort, and difficulty for drivers to communicate with the outside world in the cabs of existing coal mine transport equipment.

[0005] This utility model solves the above problems through the following technical means:

[0006] A mining transport vehicle cab structure, characterized in that it includes a cab, a door installed on one side of the cab, a guide rail window installed on the other side of the cab, an outward-curving window installed on the front side of the cab, and a protective window installed on the rear side of the cab, wherein: the guide rail window includes a sliding window and two L-shaped guide rails; pulleys are installed at the four corners of the sliding window, multiple handles are symmetrically installed on the horizontal frame of the sliding window, and two window locks are symmetrically installed on the vertical frame of the sliding window; the L-shaped guide rail is composed of vertical rails and horizontal rails, and the connection between the vertical rails and horizontal rails is transitioned by an arc-shaped track, the horizontal rail is close to the inner top surface of the cab, and the vertical rail is close to the inner side surface of the cab; the pulleys are rotatably installed in the L-shaped guide rails; locking pins are provided on the inner side and bottom of the horizontal rails, and the locking pins work in conjunction with the window locks to complete the limiting function of the sliding window.

[0007] Preferably, a control lever is swayably installed on the lower inner side of the window lock, and a locking head is swayably installed on the upper inner side of the window lock. The top of the control lever is connected to the bottom of the locking head through a pivot. By swinging the control lever, the locking head can be moved to engage with the lock pin limit position. A torsion spring is provided between the control lever or the locking head and the inner wall of the window lock.

[0008] Preferably, the top surface of the cab is equipped with a lifting ring, and multiple sets of explosion-proof lights are symmetrically arranged on the upper side of the cab. Pneumatic wipers and heater vents are installed inside the cab near the guide rail window and the outward-curved window.

[0009] Preferably, the outward-folding curved window is installed on the cab via multiple sets of top hinges.

[0010] Preferably, two sets of gas springs are symmetrically arranged inside the cab near the outward-folding curved window. The bottom of the gas spring is mounted on the base via a pivot, and the base is located at the bottom of the curved window. The top of the gas spring is connected to the inner end of the transmission arm via a pivot, and the other end of the transmission arm is fixed to the frame of the cab near the curved window. The contraction and retraction of the gas spring can drive the curved window to open around the top hinge.

[0011] Preferably, a protective mesh panel is installed on the outside of the protective window.

[0012] The cab structure of this mining transport vehicle has the following beneficial effects:

[0013] The structure adopts an integrated modular design, with the cab featuring a unibody design that allows for movement via a top-mounted lifting ring, enabling direct installation with existing mining vehicles. The fully enclosed cab effectively prevents safety hazards such as falling objects, flying particles, and intrusion of underground anchor cables or support netting into the cab. The outward-folding curved windows not only increase visibility but also have an outward-folding function. Furthermore, the guide rail windows can slide entirely to the top of the cab, facilitating communication between the driver and other miners underground, and enabling the driver to escape from the cab if the vehicle malfunctions and the doors cannot be opened.

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 8As shown, the cab structure of the mining transport vehicle includes a cab 1, a door 2 installed on one side of the cab 1, a guide rail window 3 installed on the other side of the cab 1, an outward-curved window 4 installed on the front side of the cab 1, and a protective window 5 installed on the rear side of the cab 1. In the figure, a lifting ring 101 is provided on the top surface of the cab 1, and multiple sets of explosion-proof lights 102 are symmetrically arranged on the upper side of the cab 1. Pneumatic wipers 103 and heater vents 104 are installed inside the cab 1 near the guide rail window 3 and the outward-curved window 4.

[0027] It should be noted that this structure adopts an integrated modular design, with the cab using an integral design that allows for movement via a top-mounted lifting ring, enabling direct installation with existing mining vehicles. The cab is a fully enclosed structure, effectively preventing safety hazards such as falling objects, flying particles, and intrusion of underground anchor cables or support netting into the cab.

[0028] In the figure, the curved window 401 of the outward-folding curved window 4 is installed on the cab 1 via multiple sets of top hinges 402. The curved surface of the curved window 401 is 270°, and the end of the flat glass turns 90° and continues to extend. In this embodiment, two sets of gas springs 403 are symmetrically arranged inside the cab 1 near the outward-folding curved window 4. The bottom of the gas spring 403 is mounted on the base 404 via a pivot. The base 404 is fixed to the bottom of the front window of the cab 1. The gas springs 403 are distributed on both sides of the front window of the cab 1. The top of the gas spring 403 is connected to the bottom hole of the L-shaped transmission arm 405 via a pivot. The other end of the transmission arm 405 is fixed to the non-moving, load-bearing frame of the cab near the curved window 401. Figure 5 In this configuration, since the transmission arm 405 is fixed, the retraction of the gas spring 403 will drive the base 404 and the curved window 401 to move. When the gas spring 403 extends, it will cause the curved window 401 to flip outward and open around the top hinge 402. The outward-flipping curved window 401 not only increases the field of vision but also has an outward-flipping function, which greatly facilitates the operator's work.

[0029] In the figure, a protective mesh plate 501 is installed on the outside of the protective window 5. The protective mesh plate 501 is located outside the driver's cab and can be positioned by bolts.

[0030] In the figure, the guide window 3 includes a sliding window 301 and two L-shaped guide rails 302; pulleys 303 are installed at the four corners of the sliding window 301, multiple handles 304 are symmetrically installed on the horizontal frame of the sliding window 301, and two window locks 305 are symmetrically installed on the vertical frame of the sliding window 301; the L-shaped guide rail 302 is composed of a vertical rail 306 and a horizontal rail 307, and the connection between the vertical rail 306 and the horizontal rail 307 is transitioned by an arc-shaped track. The horizontal rail 307 is close to the inner top surface of the cab 1, and the vertical rail 306 is close to the inner side of the cab 1; the pulleys 303 are rotatably installed in the L-shaped guide rail 302; a locking pin 308 is provided on the inner side and bottom of the horizontal rail 307, and the locking pin 308 works with the window locks 305 to complete the limiting work of the sliding window 301.

[0031] In practical applications, four pulleys 303 are installed in the L-shaped guide rails 302 on both sides. By pushing and pulling the handle 304, the guide rail window can be slid up to the top of the cab as a whole, which can facilitate communication between the underground driver and other miners. It can also facilitate the driver to get out of the cab when the vehicle door cannot be opened due to an underground vehicle malfunction.

[0032] It should be noted that the window lock 305 can adopt the existing structure, or it can adopt the following structure: a control lever 309 is swayably installed on the lower inner side of the window lock 305, and a latch 310 is swayably installed on the upper inner side of the window lock 305. The top of the control lever 309 is connected to the bottom of the latch 310 through a pivot. By swinging the control lever 309, the latch 310 can be moved to engage with the lock pin 308 for limiting. A torsion spring is provided between the control lever 309 or the latch 310 and the inner wall of the window lock 305. The torsion spring is used to reset the latch 310.

[0033] This utility model provides a cab structure for a mining transport vehicle. The structure adopts an integrated modular design and a fully enclosed structure, which can solve the technical problems of safety, comfort, and difficulty for drivers to communicate with the outside world in the cabs of existing coal mine transport equipment.
