Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment maintenance technology, and in particular to a piston rod oiling and maintenance device. Background Technology

[0002] Self-propelled tail sections for belt conveyors are mobile devices used in conjunction with belt conveyors and transfer conveyors in fully mechanized mining and tunneling faces of coal mines. They mainly consist of guide rails, a frame, a pushing cylinder, a height adjustment cylinder, a deviation adjustment cylinder, and an electro-hydraulic control system. Due to the presence of multiple piston rod structures, rust-preventive oil must be applied to the oil port mating surfaces and exposed piston rod parts during storage to ensure normal operation. However, current oiling devices typically require ample oiling space, making it difficult to conveniently oil the inner areas where the gap between the piston rod and the frame is small. Therefore, improvements are needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a piston rod oiling and maintenance device that can quickly apply oil to the exposed part of the piston rod and the oil port mating surface, and is suitable for oiling operations in small spaces, with outstanding practicality.

[0004] The technical solution adopted by this utility model is as follows: A piston rod oiling and maintenance device is provided, including an oil storage box arranged in a left-right direction; the oil storage box has a strip-shaped structure; an installation groove is provided in the middle of the oil storage box; a control screw is arranged inside the oil storage box in a left-right direction; the left and right ends of the control screw are respectively rotatably connected to the left and right ends inside the oil storage box; the control screw sealably passes through the left and right ends of the installation groove; a handwheel is provided in the installation groove; the handwheel is correspondingly sleeved and fixed on the control screw; the threads on the left and right sides of the control screw have opposite directions; piston blocks are slidably fitted on the left and right sides inside the oil storage box; the piston blocks are threadedly connected to the control screw; oil outlet pipes are respectively connected to the left and right sides of the lower end of the oil storage box; brackets are respectively fixed on the left and right sides of the front end of the oil storage box; an oiling adjustment mechanism is provided between the two brackets.

[0005] The oiling adjustment mechanism includes a support rod arranged in the left-right direction; positioning tooth sleeves are respectively sleeved and fixed at both ends of the support rod; a toothed groove is opened at the bottom of the bracket; the positioning tooth sleeves are correspondingly engaged with the toothed grooves on the bracket on the same side; one end of the oil outlet pipe is connected to the oil storage box, and the other end is fixed to the support rod; the oil outlet pipe is respectively connected to the front and rear sides of the support rod; multiple oil outlet micro-holes are distributed on the surface of the oil outlet pipe along its direction.

[0006] To further optimize this technical solution, the oil storage box and support rod of the piston rod oiling and maintenance device are connected by a liner; the oil outlet pipe is fixed to the surface of the liner accordingly.

[0007] To further optimize this technical solution, a reinforcing pin is slidably inserted through the front end of the bracket of the piston rod oiling and maintenance device in the front-rear direction; the front part of the reinforcing pin is connected to the front end of the bracket by a tension spring; the rear end of the reinforcing pin is engaged with the front side of the positioning tooth sleeve.

[0008] To further optimize this technical solution, the surface of the oil outlet pipe of the piston rod oiling and maintenance device is covered with a layer of fluff.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The handwheel can drive the control screw to rotate. By controlling the screw to rotate in opposite directions, the piston blocks on the left and right sides inside the oil reservoir can move synchronously in opposite directions, achieving the effect of simultaneously injecting oil into the oil outlet pipes on both the front and rear sides.

[0011] One end of the oil outlet pipe is connected to the oil reservoir, and the other end is fixed to the support rod. The oil outlet pipe can be passed around the piston rod surface by the support rod, so that the oil outlet pipe can be fitted onto the piston rod. There are multiple oil outlet micro-holes distributed along the direction of the oil outlet pipe. The oil outlet micro-holes can flow out rust-preventive oil. By moving the oil outlet pipe along the piston rod surface, the piston rod can be oiled.

[0012] 2. Positioning toothed sleeves are fitted and fixed at both ends of the support rod. The bottom of the bracket has a toothed groove. The positioning toothed sleeves and the toothed grooves on the same side of the bracket are matched and engaged. The support rod can wind the oil pipe and, combined with the toothed grooves on the bracket, can position the positioning toothed sleeves to achieve the positioning of the support rod. This allows the oil pipe to fit and adapt to piston rods of different diameters, making it highly practical. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-2As shown, the piston rod oiling and maintenance device includes an oil reservoir 1 arranged in the left-right direction (the upper end of the oil reservoir 1 is provided with an oil replenishment port for easy replenishment of anti-rust oil); the oil reservoir 1 has a strip-shaped structure; an installation groove 2 is provided in the middle of the oil reservoir 1; a control screw 3 is arranged in the left-right direction inside the oil reservoir 1; the left and right ends of the control screw 3 are respectively rotatably connected to the left and right ends inside the oil reservoir 1; the control screw 3 sealably passes through the left and right ends of the installation groove 2; a handwheel 4 is provided in the installation groove 2; the handwheel 4 is correspondingly sleeved and fixed on the control screw 3; the threads on the left and right sides of the control screw 3 have opposite directions; piston blocks 5 are slidably fitted on the left and right sides inside the oil reservoir 1; the piston blocks 5 are threadedly connected to the control screw 3; oil outlet pipes 6 are respectively connected to the left and right sides of the lower end of the oil reservoir 1; brackets 7 are fixed on the left and right sides of the front end of the oil reservoir 1; an oiling adjustment mechanism is provided between the two brackets 7;

[0019] like Figure 1 As shown, the oiling adjustment mechanism includes a support rod 8 arranged in the left-right direction; positioning tooth sleeves 9 are respectively sleeved and fixed at the left and right ends of the support rod 8; the bottom of the bracket 7 has a toothed groove 10; the positioning tooth sleeve 9 and the toothed groove 10 on the same side of the bracket 7 are correspondingly engaged; one end of the oil outlet pipe 6 is connected to the oil storage box 1, and the other end is fixed to the support rod 8; the oil outlet pipe 6 is respectively connected to the front and rear sides of the support rod 8; multiple oil outlet microholes 11 are distributed on the surface of the oil outlet pipe 6 along its direction.

[0020] By inserting the support rod 8 into the gap inside the piston rod, the oil outlet pipe 6 can be easily passed through the relatively narrow gap inside the piston rod using the gravity of the support rod 8, making it easy to operate in a small space. Then, the support rod 8 is wrapped around the piston rod so that the oil outlet pipe 6 fits against the piston rod surface. If the oil outlet pipe 6 is found to be too long, it can be appropriately wound around the support rod 8 to shorten its length. Finally, the positioning sleeve 9 is positioned by the toothed groove 10 on the bracket, thus positioning the support rod 8 so that a part of the oil outlet pipe 6 can fit tightly against the piston rod.

[0021] After completing the above preparations, the handwheel 4 is rubbed to drive the control screw 3 to rotate, which drives the two piston blocks 5 to squeeze rust-preventive oil into the corresponding oil outlet pipes 6. After the rust-preventive oil flows out from the oil outlet micro-hole 11, the piston rod surface can be fully coated by moving the device along the piston rod axis and rubbing it appropriately in the circumference.

[0022] In the above process, the arrangement of two oil outlet pipes 6, one in front and one behind, can achieve the effect of "checking for omissions and filling gaps," ensuring a more comprehensive oiling process and facilitating oiling at the joint surfaces of the piston rod and the oil port. Furthermore, if reduced oiling is detected, the handwheel 4 can be turned at any time to promptly release oil through the oil outlet micro-holes 11.

[0023] like Figure 1As shown, the oil reservoir 1 and the support rod 8 are connected by a lining 12; the oil outlet pipe 6 is fixed to the surface of the lining 12. The lining 12 can support and reinforce the oil outlet pipe 6, and can also block the oil during application, reducing the problem of rust-preventive oil dripping.

[0024] like Figure 2 As shown, a reinforcing pin 13 slides through the front end of the bracket 7 in the front-back direction; the front part of the reinforcing pin 13 is connected to the front end of the bracket 7 by a tension spring 14; the rear end of the reinforcing pin 13 is engaged with the front side of the positioning tooth sleeve 9.

[0025] The tension spring 14 allows the reinforcing pin 13 to further engage and reinforce the positioning tooth sleeve 9, improving the stability of the support rod 8 and ensuring that the support rod 8 will not fall off the bracket 7 even when adjusted to a downward angle, thus further expanding the applicability of this device.

[0026] like Figure 3 As shown, the surface of the oil outlet pipe 6 is covered with a fluffy layer 15. The fluffy layer 15 allows for more even application of rust-preventive oil to the piston rod.
