[0025] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0026] This application discloses a door assembly for a wet spraying machine cab.

[0027] Reference Figs. 1-3 The system includes a cab body 1 and a door assembly 2. Door openings are located at the front and left front of the cab body 1. The door assembly 2 includes a main body 3 with a closed-loop structure. The left end of the main body 3 is bent into an arc, making it approximately a horizontal "L" shape. The left end of the main body 3 is called the arc end 4, and the right end is called the non-arc end 5. The main body 3 is formed into two surfaces with an included angle. The surface of the main body 3 closer to the arc end 4 is called the first surface 17, and the surface of the main body 3 away from the arc end 4 is called the second surface 18. The length of the first surface 17 is less than the length of the second surface 18. The door assembly 2 is located at the door opening, and the arc end 4 of the door assembly 2 is rotatably connected to the cab body 1. Because the door assembly 2 includes two surfaces with an included angle, the door assembly 2 and the cab body 1 are connected in a rotatable manner. The cab body 1 together forms an approximately rectangular driving space. The door assembly 2 does not change the shape of the cab, but utilizes the corner of the cab to allow the driver to open the door assembly 2. When the main body 3 is opened 90° around the cab body 1, the "L"-shaped main body 3 ensures that the dynamic minimum entry size H1 of the door assembly is greater than or equal to the static minimum entry size H2 of the door assembly. This provides the driver with more space to enter or leave the cab, thus enhancing the driver's sense of security. It also complies with the safety requirements of GB21500 for trackless tire-type mining vehicles in underground mines. Furthermore, when the door assembly is closed, the static minimum entry size of the door assembly is less than 550mm, thereby saving cab space and facilitating the safe operation of the wet spraying machine, thus improving safety.

[0028] Furthermore, in this embodiment, the main body 3 includes a first horizontal bar 6 in an approximately "L" shape, a second horizontal bar 7 in an approximately "L" shape, a first vertical bar 8, and a second vertical bar 9. The first horizontal bar 6 and the second horizontal bar 7 are symmetrically arranged, as are the first vertical bar 8 and the second vertical bar 9. The upper end of the first vertical bar 8 is welded to the left end of the first horizontal bar 6, and the other end is welded to the left end of the second horizontal bar 7. The upper end of the second vertical bar 9 is welded to the right end of the first horizontal bar 6, and the other end is welded to the right end of the second horizontal bar 7. The connection between the first vertical bar 8 and the first horizontal bar 6 and the second horizontal bar 7 is arc-shaped, and the connection between the second vertical bar 9 and the first horizontal bar 6 and the second horizontal bar 7 is also arc-shaped. The main body 3 has a pin hole portion 14 welded on the first vertical bar 8, and a pin hole is provided on the pin hole portion 14. The cab body has a pin shaft portion 15 welded near the first vertical bar 8, and a pin shaft is integrally formed on the pin shaft portion 15. The pin shaft and the pin hole cooperate to make the main body 3 rotatably connected to the cab body.

[0029] Furthermore, in this embodiment, the door assembly 2 also includes a third horizontal bar 10 in an approximately "L" shape. The third horizontal bar 10 is located on the upper part of the main body 3. The left end of the third horizontal bar 10 is welded to the first vertical bar 8, and the right end is welded to the second vertical bar 9. The third horizontal bar 10 is parallel to the first horizontal bar 6. The third horizontal bar 10 and the main body 3 form two closed-loop structures, which are respectively called the first closed-loop structure 11 and the second closed-loop structure 12. The first closed-loop structure 11 is located above the second closed-loop structure 12. The third horizontal bar 10 serves as a handrail for getting on and off the vehicle, opening and closing the door.

[0030] Furthermore, in this embodiment, the door assembly 2 also includes an auxiliary body 13, which is arranged along the direction of the third crossbar 10 and filled within the second closed-loop structure 12, allowing the driver to observe the outside of the cab through the first closed-loop structure 11.

[0031] Furthermore, in this embodiment, the auxiliary body 13 may be a steel plate or a mesh plate.

[0032] Furthermore, in this embodiment, the dynamic minimum entrance size H1 of the gate assembly is ≥550mm, thus complying with the requirements of GB21500 Safety Requirements for Trackless Tire-type Mining Vehicles in Underground Mines.

[0033] Furthermore, in this embodiment, the pin hole is opened below the pin hole portion 14, and the pin shaft is integrally formed above the pin shaft portion 15, so that the main body portion 3 can be sleeved on the pin shaft of the cab body through the pin hole portion 14, so that the main body portion 3 will not detach from the cab body under the action of gravity, thereby allowing the user to disassemble or install the main body portion 3 upwards or downwards.

[0034] Furthermore, in this embodiment, the third crossbar 10 of the non-arc end 5 of the door assembly 2 is bolted with a lock 16. The lock 16 is located on the inner wall of the third crossbar 10 and does not occupy space in the width of the wet spraying machine. The cab body 1 is bolted with a connecting hole for cooperating with the lock 16 near the non-arc end 5. The door assembly 2 is locked to the cab body through the lock 16 and the connecting hole.

[0035] Furthermore, in this embodiment, the cab body 1 and the door assembly 2 can also be disassembled and rotated via a 233-9012 hinge manufactured by Deluxe.

[0036] It should be noted that the various embodiments of this application can be arbitrarily combined into new embodiments, provided that the solutions do not conflict and the technical solutions can coexist.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
