Description

Technical Field

[0001] The utility model belongs to the technical field of electric flipping platforms, and particularly relates to an electric flipping platform. Background Technique

[0002] In the huge system of coal mining, as a key equipment for coal transportation, the performance and reliability of the scraper conveyor are directly related to the production efficiency and safety of the mine. The middle trough inside the scraper conveyor, as an important component for carrying coal and guiding it to move along the conveyor, is in a working environment of high load and high wear for a long time. With the continuous transportation of coal, the bottom and side walls of the middle trough will gradually wear, which not only affects the conveying efficiency of the conveyor, but also may cause faults such as coal leakage, chain jamming or even chain breakage due to severe wear, seriously endangering the safety production of the mine.

[0003] The traditional method of repairing and welding wear-resistant layers on the middle trough mainly relies on manual operation. The specific process includes: first, use lifting equipment (such as a crane) to lift the heavy middle trough and fix it in the working area. Subsequently, the welder holds a welding torch and performs manual welding operations around the middle trough to repair the worn area and weld on the wear-resistant layer. Since the angle needs to be continuously adjusted manually during the construction process, the danger coefficient of the construction is increased, and it is very difficult to carry out maintenance work in some places with tricky angles and narrow construction surfaces. The operation is time-consuming and laborious, and the construction period cannot be guaranteed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electric flipping platform to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An electric flipping platform, comprising:

[0007] A bottom plate, on the top end of which a flipping frame is movably installed;

[0008] A fixing component, which is arranged on both sides of the flipping frame. The fixing component includes fixing blocks fixedly installed on both sides of the flipping frame, and a pressing plate is movably installed on one side of each fixing block.

[0009] Preferably, two support plates are fixedly installed on the top end of the bottom plate. A rotating shaft is movably installed between the two support plates through bearings, and the flipping frame is fixedly installed on the outer side of the rotating shaft.

[0010] Preferably, a driving member is installed on one side of the support plate through a fixing seat, and the output end of the driving member is in shaft transmission connection with the rotating shaft through a coupling.

[0011] Preferably, fixing blocks are fixedly installed at the four corners on both sides of the flipping frame, and fixing bolts are installed inside the fixing blocks by screw threads.

[0012] Preferably, a pressing plate is movably installed on one side of the fixing block, and two connecting grooves are formed inside the pressing plate.

[0013] Preferably, the pressing plate is sleeved outside the fixing bolt through the connecting groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment:

[0021] Please refer to Figure 1 - Figure 2 as shown, an electric flipping platform includes:

[0022] A bottom plate 1, and a flipping frame 11 is movably installed at the top of the bottom plate 1;

[0023] The fixing component 2 is arranged on both sides of the flipping frame 11. The fixing component 2 includes fixing blocks 21 fixedly installed on both sides of the flipping frame 11, and a pressing plate 23 is movably installed on one side of the fixing block 21.

[0024] Specifically, two support plates 12 are fixedly installed at the top of the bottom plate 1. A rotating shaft 13 is movably installed between the two support plates 12 through bearings. A flipping frame 11 is fixedly installed on the outer side of the rotating shaft 13. A driving member 14 is installed on one side of the support plate 12 through a fixing seat. The output end of the driving member 14 is in shaft transmission connection with the rotating shaft 13 through a coupling. Fixing blocks 21 are fixedly installed at the four corners on both sides of the flipping frame 11. Fixing bolts 22 are installed in the fixing blocks 21 by screw threads. A pressing plate 23 is movably installed on one side of the fixing block 21. Two connecting grooves 24 are formed inside the pressing plate 23. The pressing plate 23 is sleeved on the outer side of the fixing bolt 22 through the connecting grooves 24.

[0025] As can be seen from the above, the rotating shaft 13 can drive the flipping frame 11 to rotate, and then the flipping frame 11 drives the middle trough to flip. The driving member 14 is composed of a stepping motor and a speed reducer. In order to realize the slow driving of the middle trough to rotate for convenient welding, when the fixing bolt 22 is tightened, it will drive the pressing plate 23 to approach the flipping frame 11 and then tightly press the middle trough to fix the middle trough.

[0026] This application can be applied in large-scale coal mine operation scenarios. For example, in a large coal mine enterprise, after the middle trough of the underground scraper conveyor has been running for a long time, it has suffered serious wear, affecting the coal conveying efficiency and safety. In order to repair the middle trough in time and restore the normal operation of the scraper conveyor, the enterprise decides to use the device of this application to carry out surfacing and wear-resistant treatment on the middle trough. The specific implementation steps are as follows:

[0027] S1. First, conduct a comprehensive inspection of the electric flipping platform to ensure that all its components are intact and in a normal working state;

[0028] S2. Use special transportation equipment to transport the middle trough to be repaired to the maintenance workshop and carefully place it near the electric flipping platform;

[0029] S3. First, place the flipping frame 11 horizontally, then place the middle trough above the flipping frame 11 from the side, and then rotate the fixing bolt 22 to tightly press the pressing plate 23 on the middle trough until the middle trough is firmly fixed. The same operation is carried out on the reverse side;

[0030] S4. Wear personal protective equipment such as welding masks, protective clothing, gloves, etc. to ensure the safety of the operators;

[0031] S5. Start the driving member 14 to drive the flipping frame 11 to rotate at a constant speed, set to rotate one circle per minute;

[0032] After S6, when the flipping frame 11 stops rotating after welding is completed, the welding quality can be inspected at this time. If necessary, local repair or adjustment can be carried out.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
