Description

Technical Field

[0001] The present invention relates to the technical field of mine bin equipment, and in particular to a safety cover lifting device for a mine bin and a use method thereof. Background Art

[0002] The safety cover lifting device for mine bin is a mechanical device that can automatically open and close the mine bin cover. It controls the mine bin cover through a specific lifting mechanism, such as a motor, a winch, a traction rope, etc., so that it can be automatically opened or closed when needed, thereby ensuring the safety of the mine bin in a non-operating state and improving the loading and unloading efficiency of ore during operation.

[0003] Existing safety cover lifting devices for mine bins usually have a simple structure and can only realize the lifting effect of the cover to control the opening and closing of the bin door. However, when loading and unloading materials, although many mine bins can automatically control the opening and closing of the bin door, the bin door diameter is large. During the operation of the mine bin, the temperature in the mine bin is greatly affected by the external environment. Frequent opening and closing of the bin door will cause frequent temperature exchanges inside and outside the mine bin, thereby affecting the temperature stability in the mine bin, which has an adverse effect on the stored materials, such as causing material agglomeration and deterioration. In view of the shortcomings of the prior art, the present invention provides a safety cover lifting device for a mine bin and a use method to solve the above problems. Summary of the invention

Improvements are made on the traditional lifting device so that the lifting device can not only control the lifting of the bin cover body, but also control the lifting and opening and closing of the portable bin door on the bin cover body. During the operation of the mine bin, the management personnel can choose to open the bin cover body or the portable bin door according to actual conditions, thereby improving work efficiency. When loading and unloading a small amount of materials, it is only necessary to open the portable bin door for quick operation without waiting for the bin cover body to be fully opened. Therefore, when loading and unloading a small amount of materials, the bin door diameter is small, and the temperature inside the mine bin body is less affected, thereby ensuring the temperature stability inside the mine bin body, avoiding material agglomeration and deterioration, and meeting usage requirements.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a safety cover lifting device for a mine bin, comprising a bearing platform arranged on a mine bin body, a bin cover body being arranged on the mine bin body, and a portable bin door being rotatably connected to the bin cover body;

[0038] The embodiments of the present application provide a safety cover lifting device for a mine bin and a method for using the safety cover lifting device, thereby solving the problem that the existing safety cover lifting device for a mine bin usually has a single structure and can only lift the cover to control the opening and closing of the bin door. However, when loading and unloading materials, although many mine bins can automatically control the opening and closing of the bin door, the bin door diameter is large. During the operation of the mine bin, the temperature in the mine bin is greatly affected by the external environment. Frequent opening and closing of the bin door will cause frequent temperature exchanges between the inside and outside of the mine bin, thereby affecting the temperature stability in the mine bin, which has an adverse effect on the stored materials, such as causing problems such as material agglomeration and deterioration.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] The carrying platform 4 is provided with a first lifting unit 5 for driving the bin cover body 2 to lift;

[0042] The first lifting unit 5 includes a guide rail frame 51 arranged on the carrying platform 4 and an adjustment platform 52 sleeved on the guide rail frame 51. The first lifting unit 5 also includes a driving structure for driving the adjustment platform 52. The bin cover body 2 is provided with a support arm 21, and the support arm 21 is clamped with the adjustment platform 52.

[0043] The adjusting platform 52 is provided with a second lifting unit 6 for driving the portable door 3 to adjust.

[0044] The safety cover lifting device for the mine bin is improved on the traditional lifting device, so that the lifting device can not only control the lifting of the bin cover body 2, but also control the lifting, opening and closing of the portable bin door 3 on the bin cover body 2. During the operation of the mine bin, the management personnel can choose to open the bin cover body 2 or the portable bin door 3 according to the actual situation, so as to improve the work efficiency. When loading and unloading a small amount of materials, it is only necessary to open the portable bin door 3 for quick operation without waiting for the bin cover body 2 to be fully opened. Therefore, when loading and unloading a small amount of materials, the bin door diameter is small, and the temperature inside the mine bin body 1 is less affected, so as to ensure the temperature stability inside the mine bin body 1, avoid the agglomeration and deterioration of the materials, and meet the use requirements.

At the same time, in conjunction with the design of the torsion spring 32, the portable compartment door 3 always maintains a fit with the compartment cover body 2 when the compartment cover body 2 is not subjected to external force.

[0054] A sleeve 521 is fixedly connected to the adjustment platform 52, a plug-in column 211 is provided on the support arm 21, the plug-in column 211 is movably plugged into the sleeve 521, a locking assembly 7 for locking the position of the plug-in column 211 is provided on the sleeve 521, the locking assembly 7 includes a guide rod 71 fixedly connected to the two sets of sleeves 521 and a limit platform 72 slidably connected to the guide rod 71, a locking rod 73 is provided on the limit platform 72, a locking hole 212 is provided on the plug-in column 211, the locking rod 73 is movably clamped in the locking hole 212, a double-threaded screw 74 is rotatably connected to the sleeve 521, and the double-threaded screw 74 is threadedly connected to the limit platform 72;

[0055] The device adopts a clamping method of the sleeve 521 and the plug-in column 211, and cooperates with the design of the locking assembly 7, so that the bin cover body 2 and the portable bin door 3 are easy to install. Therefore, when the bin cover body 2 and the portable bin door 3 are damaged, they are also easy to quickly disassemble and maintain, so that the bin cover body 2 and the portable bin door 3 have good stability;

[0056] When installing the bin cover body 2 and the portable bin door 3, directly align the bin cover body 2 and the portable bin door 3 with the position of the supporting platform 4 and lift them so that the plug-in column 211 is aligned with the interior of the sleeve 521 and inserted. After being fully inserted, rotate the double-threaded screw 74 so that the double-threaded screw 74 drives the limit platform 72 to move along the guide rod 71, and the limit platform 72 drives the locking rod 73 to move, and finally the locking rod 73 is inserted into the interior of the locking hole 212 to complete the installation of the bin cover body 2 and the portable bin door 3.
