Description

Technical Field

[0001] This utility model relates to the field of mining transportation equipment technology, and in particular to a vertical shaft cage mine car unloading device. Background Technology

[0002] In mining operations, shaft cages are crucial equipment for transporting mine cars, personnel, and materials. After the mine cars are raised to the surface by the cage, they need to be safely and efficiently removed from the cage for subsequent ore unloading operations. Existing shaft cage mine cars have some problems, such as swaying during cage lifting and lowering, causing frequent impacts between the cars and the cage, which can lead to structural deformation and ultimately make it difficult to remove the cars. Therefore, this paper presents a shaft cage mine car removal device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a vertical shaft cage mine car unloading device. Two first hydraulic push rods push the connecting block and rectangular frame upwards, which in turn drives two clamping rods to rotate upwards, clamping the mine car. A controller module energizes an electromagnet module, causing the electromagnet to attract and secure the mine car, thus significantly reducing swaying during cage lifting and lowering, preventing impacts on the cage structure, extending the cage's lifespan, and ensuring smooth mine car unloading. This overcomes the deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vertical shaft cage mine car unloading device includes a cage bottom plate. Two rails are symmetrically fixed to the upper end of the cage bottom plate. Two U-shaped seats are symmetrically fixed to the upper end of the cage bottom plate and located between the two rails. Clamping rods are rotatably installed on each of the two U-shaped seats. A lifting component is provided below the two clamping rods. A gantry frame is provided on the upper side of the cage bottom plate. An adsorption component is provided on one side of the horizontal section of the gantry frame. A pushing component is installed at the lower end of the horizontal section of the gantry frame.

[0006] As a further embodiment of this utility model: the lifting assembly includes two first hydraulic push rods symmetrically fixed to the upper end of the bottom plate of the cage, each of the two first hydraulic push rods having a connecting block fixed to its upper end, a rectangular frame connecting the two connecting blocks, and two clamping rods slidably engaging the inner side of the rectangular frame.

[0007] As a further improvement of this utility model: the adsorption assembly includes two positioning rods symmetrically fixed on one side of the horizontal section of the gantry frame, and an electromagnet module is installed at one end of each positioning rod.

[0008] As a further embodiment of this utility model: the pushing component includes a fixing plate fixed to the lower end of the horizontal section of the gantry frame, a second hydraulic push rod fixed to one side of the fixing plate, and a push plate connected to one end of the second hydraulic push rod.

[0009] As a further improvement of this utility model: a controller module is fixed on the other side of the gantry frame, and the first hydraulic push rod, the electromagnet module, and the second hydraulic push rod are all electrically connected to the controller module.

[0010] As a further improvement of this utility model: the bottom ends of the vertical sections on both sides of the gantry frame are welded with triangular support plates between them and the bottom plate of the cage.

[0011] The beneficial effects of this utility model are as follows:

[0012] Two hydraulic push rods push the connecting block and rectangular frame upwards, which in turn drive two clamping rods to rotate upwards, clamping the mine car. The controller module energizes the electromagnet module, causing it to attract the mine car's body and secure it. This significantly reduces the likelihood of the mine car swaying during cage lifting and lowering, preventing impacts on the cage structure and extending the cage's lifespan, thus ensuring the mine car can exit smoothly.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1, referring to Figure 1-3A vertical shaft cage mine car unloading device includes a cage bottom plate 1, two rails 2 are symmetrically fixed to the upper end of the cage bottom plate 1, two U-shaped seats 8 are symmetrically fixed to the upper end of the cage bottom plate 1 and located between the two rails 2, clamping rods 5 are rotatably installed on the two U-shaped seats 8, a lifting component is provided below the two clamping rods 5, a gantry frame 3 is provided on the upper side of the cage bottom plate 1, an adsorption component is provided on one side of the horizontal section of the gantry frame 3, and a pushing component is installed at the lower end of the horizontal section of the gantry frame 3.

[0019] The lifting assembly includes two first hydraulic push rods 15 symmetrically fixed to the upper end of the cage bottom plate 1. Each of the two first hydraulic push rods 15 has a connecting block 14 fixed to its upper end. A rectangular frame 7 is connected between the two connecting blocks 14. Two clamping rods 5 are slidably engaged with the inner side of the rectangular frame 7.

[0020] The adsorption assembly includes two positioning rods 4 symmetrically fixed on one side of the horizontal section of the gantry frame 3, and an electromagnet module 6 is installed at one end of each positioning rod 4.

[0021] The pushing component includes a fixing plate 9 fixed to the lower end of the horizontal section of the gantry 3, a second hydraulic push rod 10 fixed to one side of the fixing plate 9, and a push plate 11 connected to one end of the second hydraulic push rod 10.

[0022] A controller module 12 is fixed on the other side of the gantry 3. The first hydraulic push rod 15, the electromagnet module 6, and the second hydraulic push rod 10 are all electrically connected to the controller module 12.

[0023] Triangular support plates 13 are welded between the bottom ends of the vertical sections on both sides of the gantry frame 3 and the bottom plate 1 of the cage to ensure the structural strength of the gantry frame 3 during installation.

[0024] Working principle: After the mine car is moved to the track 2 of the cage bottom plate 1, the connecting block 14 and the rectangular frame 7 are pushed up by the two first hydraulic push rods 15. The rectangular frame 7 drives the two clamping rods 5 to rotate upward, and the two clamping rods 5 clamp the mine car. The controller module 12 energizes the electromagnet module 6, so that the electromagnet module 6 attracts the body of the mine car, thereby fixing the mine car. This greatly avoids the mine car shaking during the lifting and lowering of the cage, avoids impact on the structure of the cage, and extends the service life of the cage.

[0025] When it is necessary to remove the car from the cage, the controller module 12 controls the two first hydraulic push rods 15 to retract, so that the clamping rod 5 rotates downward under the action of gravity and leaves the mine car. By cutting off the circuit of the electromagnet module 6, the second hydraulic push rod 10 pushes the push plate 11, so that the push plate 11 pushes the mine car out of the cage.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
