Description

Technical Field

[0001] The utility model belongs to the technical field of the design of protective frames for mine car cabs, and particularly relates to a collision buffer protective frame for a mine car cab. Background Technique

[0002] Mine cars are mainly used to transport the mined ore. For example, in coal mines, ore-carrying mine cars transport coal from the coal mining face to the bottom of the shaft, and then the coal is transported to the ground through lifting equipment. Its carriage structure is usually relatively simple, aiming to maximize the loading capacity, and is generally open-top, which is convenient for loading and unloading of ore. In modern large mines, mine cars are one of the key equipment for large-scale production. Only through an efficient mine car transportation system can a large amount of mined ore be transported out in time to meet market demand. For example, in some large gold mines, the amount of ore mined every day is huge, and the mine car transportation system must be able to operate continuously and stably to ensure the normal production and economic benefits of the gold mine.

[0003] The existing protective frame has a low protection strength at the door position. Since the door needs to be opened for personnel to enter, when the design is relatively complex, it is inconvenient for the driver to get in and out, and there are overall weak points.

[0025] Please refer to Figures 1 - 4 , a collision buffer protection frame for a mine car cab, including a cab body 1, a frame device 2 is arranged outside the cab body 1, and a door device 3 is arranged on one side of the frame device 2.

[0026] In this embodiment: The cab body 1 includes a cab outer shell 101. A cab door 102 is rotatably provided on one side of the cab outer shell 101. A connecting seat 103 is fixedly provided on the outer side of the cab door 102. The connecting block 304 drives the cab door 102 to open synchronously through the connecting seat 103, enabling the driver to enter the cab outer shell 101 through the frame device 2. When the driver inside the cab outer shell 101 closes the cab door 102, the protection door 301 closes synchronously, improving the convenience of closing the door.

[0027] In this embodiment: The frame device 2 includes a support frame 201. An integrated side plate 203 is fixedly provided on one side of the support frame 201. A decentralized side plate group 204 is fixedly provided on the side of the support frame 201 away from the integrated side plate 203. A support shaft 205 is provided in the middle of the decentralized side plate group 204. Two card slots 206 are symmetrically arranged on the upper and lower sides of the support frame 201. A number of reinforcing bars 202 are evenly and fixedly provided in the middle of the support frame 201. The support shaft 205 is welded to the support frame 201. The protection door 301 is hinged to the support shaft 205. The reinforcing bars 202 respectively strengthen the strength of the front and top of the support frame 201. The integrated side plate 203 protects the left side of the cab outer shell 101. The decentralized side plate group 204 and the protection door 301 are combined to protect the integrated side plate 203 and protect the right side of the cab outer shell 101.

[0028] In this embodiment: The door device 3 includes a protection door 301. Two reinforcing bars 303 are symmetrically and fixedly provided on the upper and lower sides of the protection door 301. A connecting block 304 is rotatably provided on the front of the protection door 301. A handle 302 is fixedly provided on one side of the protection door 301. The connecting block 304 is hinged to the connecting seat 103. During use, the driver pulls the protection door 301 to rotate along the support shaft 205 through the handle 302. The connecting block 304 rotates when the protection door 301 rotates. When the protection door 301 is closed, the upper and lower reinforcing bars 303 are inserted into the card slots 206 on the outer side of the support frame 201 to prevent the protection door 301 from rotating inward when being impacted. The entire support frame 201 protects the cab outer shell 101, reducing the risk of the driver being injured in a collision.

[0029] Working principle: When in use, the driver pulls the protection door 301 through the handle 302 to rotate along the support shaft 205. During the rotation of the protection door 301, the connecting block 304 is driven to rotate. The connecting block 304 drives the chamber door 102 to open synchronously through the connecting seat 103, enabling the driver to pass through the frame device 2 and enter the driver's cab housing 101. When the driver in the driver's cab housing 101 closes the chamber door 102, the protection door 301 closes synchronously, improving the convenience of closing the door. When the protection door 301 is closed, the upper and lower reinforcement rods 303 are snapped into the card slots 206 on the outer side of the support frame 201 to prevent the protection door 301 from rotating inward when being impacted. The overall support frame 201 protects the driver's cab housing 101, reducing the risk of the driver being injured in a collision. The strengthening rods 202 strengthen the strength of the front and top of the support frame 201 respectively. The integrated side plate 203 protects the left side of the driver's cab housing 101. The distributed side plate group 204 and the protection door 301 are combined to protect the integrated side plate 203 and protect the right side of the driver's cab housing 101.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
