Detailed implementation mode

[0025] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the attached drawings and preferred embodiments to detail the specific implementation mode, structure, features and their effects according to the present utility model as follows.

[0026] Embodiment 1:

[0027] A kind of underground loader cab door body provided in this embodiment is applied to the ceiling 1 of the cab, as Figure 1 、 Figure 2 、 Figure 3 shown, including a door body part 2, and the door body part 2 is rotatably connected to the ceiling 1; a locking mechanism is provided between the door body part 2 and the ceiling 1, and the locking mechanism is used for locking the door body part 2 in the closed state.

[0028] Furthermore, the door body part 2 is rotatably connected to the ceiling 1 through a bearing seat 5; the bearing seat 5 is located at the top of the ceiling 1; one end of the door body part 2 is connected to the bearing seat 5.

[0029] Furthermore, as Figure 6 、 Figure 7 、 Figure 8 shown, the door body part 2 includes an elbow main body 201, a half shaft 202, a half shaft ear hole 203 and at least one horizontal elbow 204; the half shaft 202 is located at one end of the elbow main body 201, and the half shaft ear hole 203 is located at the other end of the elbow main body 201; the horizontal elbows 204 are arranged in an array on the elbow main body 201.

[0030] Furthermore, the bottom of the elbow main body 201 extends outwards, and the horizontal elbow 204 is flush with the bottom of the elbow main body 201. In this way, it is easier to grab the horizontal elbow 204 to open and close the door through the horizontal elbow 204; at the same time, the horizontal elbow 204 being flush with the bottom of the elbow main body 201 increases the control space and boundary sense of the driving area, thereby ensuring the safety and comfort of the driver.

[0031] Furthermore, the locking mechanism is a bolt assembly 3, the bolt assembly 3 is located at the top of the ceiling 1, and one end of the door body part 2 is connected to the bolt assembly 3; as Figure 4As shown, the bolt assembly 3 includes a socket body 301, a bolt 303 provided with a threaded hole, and a handle 304; a U-shaped chute 302 is provided on the socket body 301; the bolt 303 is arranged inside the socket body 301; the handle 304 is connected to the threaded hole of the bolt 303.

[0032] When opening the door, separate the other end of the door body 2 from the bolt assembly 3, and rotate one end of the door body 2 around the plug bearing seat 5 to open the door.

[0033] Furthermore, knurling 305 is provided on the handle 304, and the outer end face of the handle 304 is a hemispherical body 306 to avoid injuries caused by accidental collisions by personnel. In some other embodiments, a rubber spherical body is provided on the hemispherical body 306 to relieve pain when personnel are accidentally collided.

[0034] The shape of the knurling 305 is straight or reticulate. Therefore, the frictional force of operation is increased, making it not easy to separate from the hand.

[0035] When the door body 2 is in the closed state, pull the bolt 303 to slide within the long side of the U-shaped chute 302 through the handle 304, and self-lock through the short side at one end of the U-shaped chute 302, so that the bolt 303 is inserted into the semi-axle ear hole 203 to lock the door body 2;

[0036] When the door body 2 is in the open state, pull the bolt 303 to slide within the long side of the U-shaped chute 302 through the handle 304, and self-lock through the short side at the other end of the U-shaped chute 302, so that the bolt 303 disengages from the semi-axle ear hole 203 to open the door body 2.

[0037] Furthermore, a travel switch bracket 4 is provided between the door body 2 and the ceiling 1, and the travel switch bracket 4 is located at the top of the ceiling 1; as Figure 5 shown, the travel switch bracket 4 is an L-shaped bent plate. A long slot 401 is provided on one side surface of the L-shaped bent plate, and a mounting hole 402 is provided on the other side surface of the L-shaped bent plate. The mounting hole 402 is used to mount the travel switch, and the travel switch is electrically connected to a buzzer alarm provided on the underground loader control box; the travel switch bracket 4 is mounted on the top of the ceiling 1 through the long slot 401.

[0038] Furthermore, the door body 2 further includes an impact plate 205 provided at the other end of the bent pipe main body 201 and below the semi-axle ear hole 203. In this way, when the door body 2 is in the closed state, the impact plate 205 is in contact with the travel switch. When the door body 2 is in the open state, the impact plate 205 is separated from the travel switch. At the same time, the travel switch sends a signal to the buzzer alarm of the electric control box to warn personnel and vehicles in the operation area, thereby ensuring the safety of the driver.

[0039] The distance value from the bottom edge of the door body part 2 to the ground of the cab is H, and the value of H is in the range of 950 mm - 1020 mm. Therefore, when the door body part 2 is closed, it can effectively protect the driver's head and shoulders, and does not affect the operation of the rear control box installed on the rear frame. Therefore, when opening and closing the cab door, the cab door does not interfere with the rear frame, and smooth opening and closing can be achieved.

[0040] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the above-disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
