Description

Technical Field

[0001] This utility model relates to the field of door locks in underground engineering, and in particular to a door lock mechanism suitable for trackless equipment in underground mines. Background Technology

[0002] In underground trackless equipment (such as trackless mining vehicles and underground operating machinery), the door lock mechanism is a key component for fixing the door panel, and its performance directly affects the safety and reliability of the equipment. In existing technologies, common door lock mechanisms used in underground trackless equipment often suffer from the following problems: complex structure leading to inconvenient operation and high manufacturing costs; in harsh working conditions such as high dust, high vibration, and high humidity underground, they are prone to jamming and failure, resulting in insufficient reliability; and the door locks have a short lifespan, with frequent replacements increasing equipment maintenance costs.

[0003] Therefore, there is an urgent need for a door lock mechanism for trackless underground equipment that is simple in structure, easy to operate, low in manufacturing cost, and can maintain high reliability and extend service life under harsh working conditions. Utility Model Content

[0004] To address the issues of insufficient reliability, complex structure, and high cost in existing door lock mechanisms for trackless underground equipment, the present invention aims to provide a door lock mechanism suitable for trackless underground equipment. This mechanism is simple in structure, easy to operate, and has low manufacturing cost. Furthermore, it can improve reliability under harsh working conditions and extend the service life of the door lock through optimized structural design.

[0005] To achieve the above objectives, the present invention provides a door lock mechanism suitable for trackless underground equipment, the specific technical solution of which is as follows:

[0006] A door lock mechanism suitable for trackless equipment in underground mines includes a locking pin, a locking pin guide plate, and a locking pin baffle. The locking pin guide plate is U-shaped, and each of the two upright plates of the locking pin guide plate is provided with a locking pin through hole. One end of the locking pin baffle is provided with a wedge. The locking pin can slide in the locking pin through hole, and one end of the locking pin passes through the two locking pin through holes and is located on the side of the locking pin baffle with the wedge.

[0007] Furthermore, the door lock mechanism also includes a spring and a limiting pin. The locking pin has a limiting pin through hole, and the limiting pin is movably disposed on the limiting pin through hole. The spring is disposed on the locking pin and located between the two upright plates of the locking pin guide plate. One end of the spring abuts against the inner side of the upright plate of the locking pin guide plate, and the other end of the spring abuts against the limiting pin.

[0008] Furthermore, the door lock mechanism also includes a handle, which is located at the end of the lock pin away from the lock pin baffle.

[0009] Furthermore, the locking pin is L-shaped.

[0010] Furthermore, the locking pin guide plate and locking pin baffle are provided with screw holes, and the locking pin guide plate and locking pin baffle are fixed by the screw holes, which makes the installation convenient, quick and stable, and has strong vibration resistance.

[0011] Furthermore, the locking pin has several protruding ridges along its axial direction, and the locking pin through hole has a groove that matches the protruding ridges.

[0012] Furthermore, the door lock mechanism also includes a spring retainer ring, which is disposed between the spring and the limiting pin. The spring retainer ring ensures that the spring is subjected to uniform force and prevents it from disengaging.

[0013] This utility model consists of only a few components, including a locking pin, a locking pin guide plate, and a baffle plate. It is easy to manufacture, significantly reducing production costs. It is also convenient to operate, automatically locking; the locking pin can be directly pulled with a handle to unlock. When closing the door, the locking pin automatically slides into the locking position along the wedge surface of the locking pin baffle plate under the spring force, requiring no additional operation and achieving "locking with a single close." The protruding edge of the locking pin cooperates with the groove of the locking pin guide plate, restricting radial rotation and preventing sliding jamming, ensuring high reliability and adaptability to harsh working conditions. Optimized component fit (such as wedge surface transition and protruding edge-groove guidance) reduces wear. Furthermore, the diameter and thickness of the locking pin and locking pin baffle plate can be adjusted according to actual working conditions to further extend their service life.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a door lock mechanism suitable for trackless underground equipment includes a locking pin 1, a locking pin guide plate 2, a locking pin baffle 3, a spring 4, a limit pin 5, a handle 6, and a spring retaining ring 8. The structure and connection relationship of each component are as follows:

[0026] Locking pin 1: It is generally L-shaped, with one end being the locking actuator and the other end being the operating end connected to the handle. The locking pin 1 has several protruding ribs 12 along its axial direction to improve sliding stability; at the same time, the locking pin 1 also has a radially penetrating limit pin through hole 11 for the installation of the limit pin 5.

[0027] Locking pin guide plate 2: It has a "U" shaped structure, including two opposing upright plates and a base plate connecting the two upright plates. The locking pin guide plate can also be a one-piece molded structure. Each of the two upright plates has a corresponding locking pin through hole 21. The inner wall of the locking pin through hole 21 has a groove 211 that mates with the protruding ridge 12 on the locking pin 1. After the locking pin 1 passes through the two locking pin through holes 21, it can slide axially. The engagement between the protruding ridge 12 and the groove 211 restricts the radial rotation of the locking pin 1, ensuring stable sliding direction. In addition, the upright plates of the locking pin guide plate 2 also have screw holes 7 for fixing it to the equipment door panel with screws.

[0028] Locking pin baffle 3: One end is provided with a wedge 31, and the other end is fixed to the equipment door panel through a screw hole 7 and a screw. The actuating end of the locking pin 1 passes through the two locking pin through holes 21 of the locking pin guide plate 2 and extends to the side of the locking pin baffle 3 with the wedge 31. Locking and unlocking are achieved by cooperating with the wedge 31.

[0029] Spring 4: Sleeves on the locking pin 1 and located between the two upright plates of the locking pin guide plate 2. One end of the spring 4 abuts against the inner side of the upright plate of the locking pin guide plate 2 near the locking pin baffle 3, and the other end abuts against the limiting pin 5 through the spring retaining ring 8, which is used to provide the return force for the locking pin 1.

[0030] Limiting pin 5: It is movably set in the limiting pin through hole 11 of the locking pin 1, with both ends extending out of the locking pin 1, and is used to limit the movement stroke of the locking pin 1: When the locking pin 1 slides, the limiting pin 5 can contact the vertical plate of the locking pin guide plate 2 or the spring 4 to limit the initial position and maximum sliding distance of the locking pin.

[0031] Spring retainer ring 8: Sleeve onto the locking pin 1, located between the spring 4 and the limiting pin 5, used to ensure that the spring 4 is evenly stressed at the limiting pin 5, preventing the spring 4 from disengaging due to uneven stress. Handle 6: Fixedly located at the end of the locking pin 1 away from the locking pin baffle 3, i.e., the operating end, for the user to grip and operate. By pulling or pushing the handle 6, the locking pin 1 can be moved to slide axially.

[0032] The locking pin guide plate 2 is fixed to the preset position of the equipment door panel through the screw hole 7 and screws; the locking pin baffle 3 is fixed to the corresponding position of the door panel to ensure that the actuating end of the locking pin 1 can extend to the wedge surface 31 side of the locking pin baffle 3. The door panel has a pre-reserved guide hole for the locking pin. One end of the locking pin is passed through the door panel, and a handle 6 is installed on the outside. The purpose of unlocking is achieved by pulling the handle 6.

[0033] Locking process: When the door is closed, the door panel moves the locking pin 1 closer to the locking pin baffle 3. The actuating end of the locking pin 1 first contacts the wedge surface 31 of the locking pin baffle 3 and slides along the wedge surface 31. During this process, the locking pin 1 overcomes the elastic force of the spring 4 and moves away from the baffle, and the spring is compressed. When the door panel is completely closed, the actuating end of the locking pin 1 slides past the wedge surface 31, the spring 4 resets and pushes the locking pin 1 to move in the opposite direction, so that the locking pin 1 is engaged in the other side of the locking pin baffle 3, thus achieving locking.

[0034] Unlocking process: The user pulls the handle 6, which causes the locking pin 1 to move away from the locking pin baffle 3, overcoming the elastic force of the spring 4. This causes the actuating end of the locking pin 1 to be released from the restriction of the locking pin baffle 3, at which point the door panel can be opened. After releasing the handle 6, the spring 4 returns to its original position, causing the locking pin 1 to return to its initial position.

[0035] Through the above-described structure and operation, this invention achieves reliable locking and convenient operation of the door lock for trackless equipment in underground mines, making it suitable for harsh underground working conditions and possessing high practical value.

[0036] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
