[0001] The utility model relates to the technical field of engineering vehicle construction equipment, in particular to a plug-in type reel locking device. Background Art

[0002] When the underground electric scraper is in transportation or vehicle maintenance, repair and assembly, the cable drum needs to be relatively still to prevent rotation from causing damage to other parts or accidental injury. The drum locking device can easily and quickly lock the cable drum in any position to ensure the needs of daily maintenance, repair and transportation.

[0003] At present, the locking device of the cable drum of electric scrapers for mining in the market is mostly a spring-type lock pin welded to the bottom of the frame. When operating, the operator needs to lean under the drum, which is not conducive to operation. In addition, the underground working environment is harsh. After a long time, the spring lock pin is easily rusted and stuck due to factors such as underground corrosion and mud and sand blockage, causing damage. If the lock pin is replaced, cutting and welding are required, and it is not conducive to replacement because it is installed at the bottom of the frame.

[0035] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0036] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0037] A plug-in reel locking device of the present application is arranged above the frame of an underground scraper, so as to facilitate the insertion of the cable reel of the underground scraper from above, so that the cable reel can remain relatively still when the underground scraper is in a transportation state or a vehicle maintenance, repair and assembly state.

[0038] like Figure 1 , Figure 2 As shown, a plug-in reel locking device of the present application includes a locking device, which is used for a reel 3, and the reel 3 is horizontal, that is, the rotating axis of the reel 3 is perpendicular to the ground. The reel 3 is located in the inner cavity of the underground scraper frame. The locking device includes a fixing portion 1 and a locking pin 2.

[0039] The fixing part 1 has a first supporting position and a second supporting position. When the lock pin 2 is located at the first supporting position, the lock pin 2 is located outside the reel 3 and the reel 3 can rotate; when the lock pin 2 is located at the second supporting position, the lock pin 2 is inserted into the reel 3 to restrict the reel 3 from rotating.

[0040] Specifically, the fixing portion 1 is provided with a limiting portion, which includes a first limiting portion 11 and a second limiting portion 12 located below the first limiting portion 11, and the first limiting portion 11 and the second limiting portion 12 are used to support the locking pin 2. The first supporting position is the first limiting portion, and the second supporting position is the second limiting portion 12.

[0041] When the locking pin 2 is located at the first limiting portion 11 , the locking pin 2 is located outside the reel 3 , and the reel 3 can rotate.

[0042] When the locking pin 2 is located at the second limiting portion 12 , the locking pin 2 is inserted into the reel 3 to limit the rotation of the reel 3 .

[0043] More specifically, if Figure 3 , Figure 4 As shown, the reel 3 includes an upper reel 31 and a lower reel 31 located directly below the upper reel 31 , and reinforcing rods 311 are arranged at intervals along the circumferential direction of the upper reel 31 .

[0044] like Figure 5 , Figure 6 As shown, the first limiting portion 11 is provided with an end through hole 111 and a middle through hole 112 , and the second limiting portion 12 is provided with a limiting hole 121 .

[0045] The locking pin 2 includes an insertion portion 21, a horizontal connecting portion 22 and a locking mechanism. The insertion portion 21 is preferably an inverted U-shape. The horizontal connecting portion 22 is located between the insertion portions 21 and is fixedly connected to the insertion portions 21. The horizontal connecting portion 22 is used to abut against the upper end surface of the limiting portion. A through hole 221 is provided in the middle of the horizontal connecting portion 22, and the through hole 221 is arranged corresponding to the middle through hole 112 and the limiting hole 121.

[0046] When the lock pin 2 is located at the first limiting portion 11, the locking mechanism sequentially passes through the through hole 221 and the middle through hole 112. When the lock pin 2 is located at the second limiting portion 12, the locking mechanism sequentially passes through the through hole 221 and the limiting hole 121. The locking mechanism is used to limit the displacement of the insertion portion 21 together with the horizontal connecting portion 22 relative to the limiting portion in the vertical direction. The locking mechanism is preferably a pin shaft 23.

[0047] The locking mechanism includes a latch 231 and a buckle 232. The buckle 232 is an elastic component and is U-shaped. One end of the buckle 232 is detachably mounted on the latch 231, and the other end is detachably inserted into the top of the latch 231. The end of the buckle 232 is triangular. When the pin 23 needs to be inserted into the horizontal connecting portion 22, the lower end of the buckle 232 is first separated from the latch 231. After the buckle 232 is inserted into the horizontal connecting portion 22, the buckle 232 is restored to lock the latch 231.

[0048] like Figure 3 , Figure 4As shown, when the reel 3 is required to be in a relatively static state, the insertion portion 21 is located at the second limiting portion 12. After the insertion portion 21 is inserted into the frame through-hole at the corresponding position, a pair of insertion rods of the insertion portion 21 abut against the outer wall of the same reinforcing rod 311, or a pair of insertion rods of the insertion portion 21 are located in the gap formed by two adjacent reinforcing rods 311.

[0049] The locking pin 2 is located above the reel 3. During the process of inserting the reel 3 from top to bottom, it is very convenient for the operator to observe, and the reel does not need to be provided with an insertion hole, so the locking pin 2 can be inserted and removed conveniently and quickly.

[0050] The second limiting portion 12 is provided with only one limiting hole 121 because when the pin shaft 2 is located at the second limiting portion 12, the rotation of the pin shaft 2 does not need to be limited. In other words, due to the harsh working environment of the underground scraper, slight rotation of the drum 3 and the pin shaft 2 during the cooperation between the two is also allowed.

[0051] A rubber sleeve is provided at the bottom of the insertion rod of the insertion portion 21 . When the insertion rod is inserted into the reel 3 , the rubber sleeve is used to reduce the wear on the reinforcing rod 311 .

[0052] The fixing part 1 is detachably connected to the vehicle frame, which is convenient for maintenance and replacement.

[0053] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
