[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.
[0024] Example 1
[0025] like Figure 1 As shown, an underground loader cab door lock device includes a main shaft 1, a latch 2, and an elbow support 3. The main shaft 1 is rotatably connected to the door panel. The main shaft 1 is provided with a handle 4 for driving the main shaft 1 to rotate. The main shaft 1 is connected to the latch 2. The loader frame is provided with a locking block 7 that matches the latch 2. The locking block 7 is located on the inner side wall of the loader frame, between the latch 2 and the frame. The latch 2 is engaged with the side of the locking block 7 facing the cab. The loader cab is provided with a baffle 8 for limiting the door panel. The baffle 8 is used to prevent the door panel from moving into the cab and limit the rotation angle. The main shaft 1 is provided with a support plate 5. The elbow support 3 is connected to the support plate 5 and is used to place the elbow. When the latch 2 and the locking block 7 are locked, the elbow support 3 is horizontal.
[0026] Turning handle 4 rotates the main shaft 1, causing the locking tongue 2 to rotate, which in turn rotates the support plate 5 and the elbow support 3. When the locking tongue 2 rotates to the end located in the slot between the locking block 7 and the loader frame, the locking tongue 2 and the locking block 7 are locked in place. At this point, the elbow support 3 is in a horizontal position, allowing the elbow to be placed on the elbow support 3 to adjust the operating handle. Whether the elbow support 3 is in the operating position indicates whether the door lock is closed, ensuring the safety of underground transport vehicles.
[0027] Example 2
[0028] The difference between this embodiment and Embodiment 1 is that: a handle holder 6 is provided on the door panel for placing the control handle 61. When the latch 2 and the lock block 7 are locked, the lower part of the support plate 5 contacts the handle holder 6, thereby limiting the position of the support plate 5 and allowing for a clearer judgment of the door lock status. When the door lock is not closed, the elbow support 3 is not in the operating position, which can promptly remind the driver to close the door lock, ensuring the safety of underground transport vehicles and avoiding the risk of driving without locking due to the handle 4 not being turned to the correct position.
[0029] The support plate 5 is detachably connected to the main shaft 1, and the elbow 3 is detachably connected to the support plate 5 by bolts, so that the maintenance and replacement of the door lock device in a poor underground environment are facilitated. The detachable mode can be various, in the embodiment, the main shaft 1 is provided with a clamping block, the clamping block is square, the support plate 5 is provided with a clamping hole, the clamping block is clamped in the clamping hole, and the main shaft 1 drives the support plate 5 to rotate by cooperation of the clamping block and the clamping hole. When the handle 4 rotates, the lock tongue 2 and the support plate 5 rotate with the handle 4 to lock.
[0030] In order to reduce wear, the handle 4 and the door plate are provided with a bushing.
