DETAILED DESCRIPTION

[0026] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

[0027] Please refer to Figures 1-7 The utility model provides a kind of lubricating device of coal mine equipment, including lubricating gun body 1 and support base frame, lubricating gun body 1 includes the gun barrel 11 of opening up and down, the lower end of gun barrel 11 is fixedly connected with bucket-shaped interface 12, the lower end of bucket-shaped interface 12 is fixedly connected with oil pipe 13, valve 14 is installed in oil pipe 13 middle, the upper end of gun barrel 11 is detachably connected with end cover 15, conical piston block 2 is slidably arranged in the inside of gun barrel 11, the upper of conical piston block 2 is connected with adjusting part 3 for adjusting the position of conical piston block 2, oil dripping pipe 4 or lubricating head 5 is detachably connected with the lower end of oil pipe 13, lubricating gun body 1 is movably placed on support base frame;

[0028] Support base frame includes base plate 6 and two groups of vertical rail 7, two groups of side support rods 61 are fixedly connected on the front and back sides of base plate 6, two groups of vertical rail 7 are symmetrically fixed on the left and right sides of the upper surface of base plate 6, movable vertical plate 8 is slidably connected to the inside of two groups of vertical rail 7, and relative fixation is realized between vertical rail 7 and movable vertical plate 8 by fixed bolt 71, U-shaped bracket 9 is rotatably connected to the front side upper end of movable vertical plate 8, and lubricating gun body 1 is detachably installed on U-shaped bracket 9.

[0029] The utility model can meet the lubricating needs of different coal mine equipment by setting oil dripping pipe 4 and lubricating head 5. Specifically, when drip irrigation lubrication is needed, oil dripping pipe 4 can be used for oil dripping lubrication to ensure that lubricating oil can drip into the required position, and when coating lubrication is needed, lubricating head 5 can be used to coat the surface of equipment lubrication position. Staff can choose different lubrication modes according to different equipment needs, improve the applicability of the device, and the use range is wider.

[0030] By setting the support base, when long-time lubrication is needed, the lubrication gun body 1 can be installed on the U-shaped bracket 9, thereby avoiding long-time lifting operation of the staff and effectively reducing the labor intensity. During use, the relative height of the movable vertical plate 8 and the two groups of vertical rails 7 can be adjusted according to the actual use scene, so as to adjust the height of the lubrication gun body 1. Secondly, the U-shaped bracket 9 is rotationally connected with the movable vertical plate 8, and the staff can adjust the inclination angle of the lubrication gun body 1 according to the actual use demand, thereby assisting the staff to complete the lubrication work more quickly.

[0031] Specifically, during lubrication, the staff can make the conical piston block 2 move downward through the adjusting piece 3. At this time, the lubricating oil in the gun barrel body 11 is pushed downward by the conical piston block 2, and flows out along the bucket-shaped interface 12, the oil pipe 13 and the oil dripping pipe 4 (lubrication head 5), thereby completing the lubrication operation. When lubrication is not needed, the valve 14 can be closed, and at this time, the oil outlet channel of the oil pipe 13 is blocked, thereby avoiding leakage of the lubricating oil. When the gun barrel body 11 needs to be filled with lubricating oil, the oil dripping pipe 4 (lubrication head 5) can be removed, and then the staff drives the conical piston block 2 to move upward through the adjusting piece 3, thereby sucking the lubricating oil from the outside into the gun barrel body 11.

[0032] Further, a threaded hole one 151 is formed through the surface center of the end cover 15, and a guide hole 152 is formed through one side of the surface of the end cover 15. The adjusting piece 3 comprises a threaded long rod 31 and a guide rod 33. The threaded long rod 31 is threadedly connected in the inside of the threaded hole one 151, the lower end of the threaded long rod 31 is rotationally connected with the conical piston block 2, the upper end of the threaded long rod 31 is fixedly connected with a rotating handle 32, and the guide rod 33 is slidingly connected in the inside of the guide hole 152.

[0033] Specifically, the end cover 15 is threadedly installed at the upper end opening of the gun barrel body 11. When the lubricating oil needs to be squeezed out, the staff rotates the rotating handle 32, the rotating handle 32 drives the threaded long rod 31 to rotate, and under the cooperation of the threaded long rod 31 and the threaded hole one 151, the rotation of the threaded long rod 31 makes the conical piston block 2 at the lower end of the threaded long rod 31 move downward. During the downward movement of the conical piston block 2, the conical piston block 2 drives the guide rod 33 to slide in the guide hole 152, so that the conical piston block 2 can only slide vertically, thereby avoiding the situation that the conical piston block 2 synchronously rotates with the threaded long rod 31.

[0034] Further, the oil dripping pipe 4 is threadedly connected with the lower end of the oil pipe 13. The lubrication head 5 comprises a hollow pipe 51 and a shunt pipe base 52. The hollow pipe 51 is threadedly connected with the lower end of the oil pipe 13, the shunt pipe base 52 is fixedly connected with the lower end of the hollow pipe 51, a plurality of shunt holes 521 are formed through the upper surface of the shunt pipe base 52, a sleeve ring 53 is threadedly sleeved with the lower end of the shunt pipe base 52, and a sponge block 54 is fixedly connected with the inside lower end of the sleeve ring 53.

[0035] Specifically, the oil outlet drip pipe 4 and the lubricating head 5 are connected with the oil pipe 13 in a threaded manner, facilitating replacement by the staff. Secondly, the oil outlet drip pipe 4 has a structure of a wide opening at the upper end and a narrow opening at the lower end, which can effectively control the flow of lubricating oil and meet the needs of drip irrigation lubrication. When using the lubricating head 5 to apply lubrication, the lubricating oil in the oil pipe 13 first flows through the hollow pipe 51, then is reasonably distributed through the plurality of distribution holes 521 on the distribution pipe base 52, and finally flows to the surface of the sponge block 54 and is absorbed by the sponge block 54. The staff can uniformly apply the lubricating oil to the lubrication parts of the equipment through the sponge block 54. The sleeve ring 53 outside the sponge block 54 is detachably connected with the distribution pipe base 52, facilitating subsequent replacement of the sponge block 54.

[0036] Further, a threaded hole two 70 is formed through the upper end of one side of the upright rail 7, and a plurality of groups of fixing holes 81 are equidistantly formed on the left and right sides of the movable vertical plate 8. The fixing bolt 71 is screwed through the threaded hole two 70 and extends to abut in the fixing hole 81 at the corresponding position.

[0037] Specifically, when adjusting the relative height of the movable vertical plate 8 and the two groups of upright rails 7, the fixing bolt 71 is first loosened so that the distal end is separated from the fixing hole 81. Then, the movable vertical plate 8 is moved upward or downward, so that the movable vertical plate 8 slides inside the two groups of upright rails 7. After adjustment, the fixing bolt 71 is tightened again to abut in the fixing hole 81 at the corresponding position.

[0038] Further, a rotating hole 82 is formed through the upper end of the front side of the movable vertical plate 8, a side plate 91 is fixedly connected to the rear side of the U-shaped bracket 9, a rotating pin 92 is fixedly connected to the rear side of the side plate 91, and the rotating pin 92 is rotatably connected inside the rotating hole 82.

[0039] Specifically, the staff can rotate the U-shaped bracket 9 according to the use demand, so as to change the inclination angle of the lubricating gun body 1. When the U-shaped bracket 9 rotates, the rotating pin 92 is driven to rotate in the rotating hole 82 through the side plate 91.

[0040] Further, a limiting arc-shaped groove 83 is formed through the front side of the movable vertical plate 8 and located at the periphery of the rotating hole 82, a long threaded column 93 is fixedly connected to the rear side of the side plate 91, the long threaded column 93 is slidingly connected inside the limiting arc-shaped groove 83, and a fixing nut 94 for limiting the rotation of the side plate 91 is threadedly sleeved on the outside of the long threaded column 93.

[0041] Specifically, when the U-shaped bracket 9 drives the lubricating gun body 1 to rotate, the U-shaped bracket 9 drives the long threaded column 93 to slide in the limiting arc-shaped groove 83 through the side plate 91. When it is necessary to lock the inclination angle of the lubricating gun body 1, the fixing nut 94 can be tightened to abut against the rear side of the movable vertical plate 8, and at this time, the rotation angle of the U-shaped bracket 9 is temporarily locked.

[0042] Further, the outer side of the gun barrel 11 is fixedly provided with a fixing ring frame 16, the upper surface of the fixing ring frame 16 is provided with a through hole 161 penetratingly formed on the left and right sides, the upper surface of the two side edges of the U-shaped bracket 9 is fixedly connected with a short threaded column 95 insertedly matched with the through hole 161, and the outer side of the short threaded column 95 is threadedly provided with a locking nut 96.

[0043] Specifically, the gun barrel 11 is further fixedly connected with a handle 17, and the staff can hold and use the lubricating gun body 1 through the handle 17. When it is necessary to lubricate a certain part for a long time, the staff can support the lubricating gun body 1 by means of a supporting base frame. At this time, the staff only needs to place the fixing ring frame 16 outside the gun barrel 11 above the U-shaped bracket 9, and during the placing process, the through hole 161 is insertedly matched with the short threaded column 95, and after the insertion is completed, the locking nut 96 is used for limiting.

[0044] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
