[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] As Figures 1-5As shown, the oiling device for spiral spikes of monolithic track bed comprises an upper shell 2, the upper shell 2 comprises an oil injection chamber 5 and an oiling chamber 4, and the oil injection chamber 5 and the oiling chamber 4 are communicated through an oil outlet hole 6, a push oil plate 52 is arranged in the oil injection chamber 5 for pushing oil to the oiling chamber 4; the oiling chamber 4 comprises an upper flange 41, a lower flange 44 and four brushes 43, the upper flange 41 is rotationally connected with the top surface of the upper shell 2, the lower flange 44 is arranged in parallel at the lower part of the upper flange 41 and is rotationally connected with the upper shell 2, the bottom of the lower flange 44 is provided with a driving device for driving the rotation of the lower flange 44, the four brushes 43 are vertically arranged between the upper flange 41 and the lower flange 44, and the four brushes 43 form a hole for inserting the spiral spike 1, the center of the upper flange 41 and the lower flange 44 is provided with a through hole, the through hole is communicated with the hole, the spiral spike 1 extends into the hole from the through hole at the center of the upper flange 41 and contacts with the four brushes 43, the two ends of each brush 43 are rotationally connected with the upper flange 41 and the lower flange 44 respectively, and each brush 43 can contact with the oil outlet hole 6.

[0035] In the embodiment, the driving device comprises a screw rod 71, a nut 73, a thrust bearing 72 and a thrust device for pushing the screw rod 71 back to the original position, the race of the thrust bearing 72 is fixedly connected with the bottom surface of the upper shell 2, the shaft of the thrust bearing 72 is connected with the lower flange 44, the nut 73 is arranged at the bottom of the hole, and the nut 73 is fixedly connected with the lower flange 44, the screw rod 71 is a ball screw rod, the screw rod 71 passes through the thrust bearing 72 and extends into the hole through the through hole at the bottom of the lower flange 44, and one end of the screw rod 71 is threadedly connected with the nut 73, and the other end is connected with the thrust device. Specifically, one end of the screw rod 71 passes through the nut 73 and is located in the hole, when the spiral spike 1 extends into the hole, the spiral spike 1 contacts with the end of the screw rod 71 away from the thrust device, with the pressing of the spiral spike 1, the screw rod 71 moves downward, so that the nut 73 threadedly connected with the screw rod 71 rotates, the nut 73 drives the lower flange 44 to rotate, the upper flange 41 and the four brushes 43 rotate synchronously, so that the spiral spike 1 is rotated and oiled.

[0036] In the embodiment, the oiling device for spiral spikes further comprises a lower shell 3, the lower shell 3 is arranged at the lower part of the upper shell 2 and is fixedly connected with the upper shell 2 through bolts, so as to facilitate assembly and disassembly, and the thrust device is arranged in the lower shell 3.

[0037] In the embodiment, the thrust device comprises a spring 74 and a guide column 75 vertically arranged on the bottom surface of the lower shell 3, one end of the spring 74 is fixedly sleeved on the guide column 75, and the other end is sleeved on the outside of the lead screw 71. The lead screw 71 is pressed downward by the spiral dowel 1 to move downward, thereby compressing the spring 74, until the lead screw 71 is in contact with the guide column 75, the lead screw 71 stops moving, the lower flange 44 stops rotating, the oiling is completed, and as the spiral dowel 1 is extracted, the spring 74 slowly rebounds upward, thereby pushing the lead screw 71 to move upward until it is reset.

[0038] In the embodiment, the lead screw 71 is provided with a limiting piece 76 for limiting the rotation of the lead screw 71. Specifically, the limiting piece 76 is a shaft sleeve, which is sleeved on the outside of the lead screw 71 and is fixedly connected with the lead screw 71 by bolts. The outside of the shaft sleeve is provided with a groove 77, and a protrusion 78 is arranged between the gap formed by the bottom surface of the lower shell 3 and the lead screw. As the lead screw 71 rises, the groove 77 cooperates with the protrusion 78 to form a limit, thereby avoiding the rotation of the lead screw 71 and allowing only linear upward and downward movement.

[0039] In the embodiment, the oil pushing plate 52 is vertically arranged in the oil injection chamber 5, a guide rod 54 is vertically arranged on the oil pushing plate 52, the guide rod 54 is threaded through the side wall of the upper shell 2, one end of the guide rod 54 is rotationally connected with the oil pushing plate 52, and the other end is connected with a hand wheel 53. Rotating the hand wheel 53 drives the guide rod 54 to rotate, and the guide rod 54 moves to one side of the oil pushing plate 52 along the side wall of the upper shell 2, thereby pushing the oil pushing plate 52 to push the oil to the oil outlet hole 6. When the oil pushing plate 52 is reset, the hand wheel 53 is reversely rotated, thereby moving the oil pushing plate 52 to one side of the hand wheel 53 to reset.

[0040] In the embodiment, an oil injection hole 51 is further formed on the top surface of the upper shell 2, which is in communication with the oil injection chamber 5, so as to facilitate oil injection into the oil injection chamber through the oil injection hole 51.

[0041] In the embodiment, the four brushes 43 are centrally symmetrically distributed, and the two ends of each brush 43 are rotationally connected with the upper flange 41 and the lower flange 44 through bearings 42. During the rotation of the lower flange 44, the upper flange 41 is synchronously rotated, and the four brushes 43 between the upper flange 41 and the lower flange 44 are synchronously rotated around the spiral dowel 1. At the same time, since the brushes 43 are connected with the upper flange 41 and the lower flange 44 through the bearings 42, the brushes 43 can also rotate around their own rotation shafts while rotating around the spiral dowel 1, thereby further ensuring the uniform oil coating of the spiral dowel 1.

[0042] In this embodiment, there are multiple oil outlet holes 6, which are arranged in a straight line on the side wall of the oil injection chamber 5 near the oil coating chamber 4. The oil pusher 52 slowly pushes the grease in the oil injection chamber 5 toward the oil outlet holes 6. The straight arrangement of the oil outlet holes 6 can make the grease evenly distributed along the axial direction of the brush 43, so that when the brush 43 applies oil, the grease can also be evenly coated on the spiral road stud 1.

[0043] The working principle of this invention is as follows:

[0044] Grease is injected into the oil filling chamber 5 through the oil filling port 51. The handwheel 53 is turned, which pushes the oil pushing plate 52 to the oil outlet 6 side, pushing the grease into the oiling chamber 4. At the same time, the spiral spike 1 is inserted into the channel through the through hole on the upper flange 41. The spiral spike 1 is pressed, and the spiral spike 1 contacts the lead screw 71, pushing the lead screw 71 to move downward. The nut 73, which is threaded to the lead screw 71, rotates, causing the lower flange 44 connected to it to rotate, thereby causing the four brushes 43 to rotate and contact the oil outlet 6 in turn, evenly applying grease. As the brushes 43 rotate, the grease is evenly coated on the spiral spike 1 to complete the oiling operation of the spiral spike 1. After the oiling is completed, the spiral spike is pulled out, and the elastic force of the spring 74 pushes the lead screw 71 to return to its original position, so as to carry out the oiling operation of the next spiral spike 1.

[0045] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
