Description

Technical Field

[0001] This utility model relates to the technical field of railway track fastener maintenance devices, specifically a track fastener oiling device. Background Technology

[0002] Rail fasteners are components used on railway tracks to connect rails and sleepers (or other types of rail foundations), also known as intermediate connecting parts. Their function is to fix the rails to the sleepers, maintain track gauge, and prevent longitudinal and lateral movement of the rails relative to the sleepers. To prevent rail fasteners from rusting and affecting the stability and safety of the track, they need to be regularly oiled to prevent corrosion. Chinese patent document CN209502034U discloses a novel hand-held rail fastener oiling device, which includes a vehicle body, a traveling mechanism, and an oil spraying system. A battery-powered motor drives the traveling wheels to rotate, enabling automatic movement. Metal sensors detect the position of the rail fasteners, and a PLC controls a solenoid valve. A gear pump and an air compressor work together to pressurize the oil and spray it onto the rail fasteners for rust prevention. Although this type of rail fastener oiling equipment can be used for oiling rail fasteners, it has the following problems in actual use: 1. It is powered by a battery to drive the wheels and the oiling components, resulting in a short continuous operating time and low reliability. Due to power limitations, it cannot be used for a long time along railway lines in the field; 2. Since the rail and the components near the rail fasteners are mostly metal, the metal sensors have poor reliability and often make detection errors, resulting in accidental oil spraying, wasting oil and polluting the environment, and even failing to operate normally.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1:

[0020] As attached Figure 1-3As shown, this utility model provides a rail fastener oiling device, including a frame 1, a traction hook 2, a pusher frame 3, a front rail wheel 4, a rear rail wheel 5, an oil tank 6, a mechanical oil spraying device, and a drive arm. The frame 1 has a traction hook 2 at its front and a pusher frame 3 at its upper rear. The front and lower rear ends of the frame 1 have a front rail wheel 4 and a rear rail wheel 5 that can be mounted on the left and right rails 9, respectively. An oil tank 6 is located in the middle of the upper end of the frame 1. The mechanical oil spraying device includes a left oil spraying device and a right oil spraying device 7. The left and right oil spraying devices 7 have the same structure and are arranged in a mirror image. The right oil spraying device 7 includes a right spray... The machine includes an oil injector 701, a right inner nozzle 702, and a right outer nozzle 703. A right transverse frame 101 is located on the right side of the frame 1, and the right oil injector 701 is fixedly installed thereon. The right oil injector 701 draws oil from the oil tank 6 and delivers it to the right inner nozzle 702 and the right outer nozzle 703. The right oil injector 701 is located above the right rail 9. An inner nozzle frame 102 and an outer nozzle frame 103 are fixedly installed on the right transverse frame 101 on the left and right sides of the right rail 9, respectively. The right inner nozzle 702 is fixedly installed on the inner nozzle frame 102, and the right outer nozzle 703 is fixedly installed on the outer nozzle frame 103. The upper rear side of the oiling device 7 is connected to the oil tank 6 via an oil supply pipe 704. A piston push rod 7011 is located on the lower rear side of the right oiling device 7, and an oil outlet pipe 705 is located on the lower front side of the right oiling device 7. The lower end of the oil outlet pipe 705 is connected to the upper ends of the right inner nozzle 702 and the right outer nozzle 703 via a three-way connector 7051. The drive arm includes a left drive arm and a right drive arm 8. The left drive arm and the right drive arm 8 have the same structure and are arranged in a mirror image. The right drive arm 8 includes a right arm vertical rod 801 and a right arm horizontal rod 802. The upper end of the right arm vertical rod 801 is integrated with the front end of the right arm horizontal rod 802. The upper part of the arm vertical rod 801 is hinged to the lower right end of the right transverse frame 101. The rear part of the right arm horizontal rod 802 is provided with an upper right roller 8021 that can push the piston rod 7011 of the right oil injection device 7. The lower end of the right arm vertical rod 801 can be pushed by the track fastener 10 on the outside of the right rail 9 to move the upper right roller 8021 forward. The upper right roller 8021 can push the piston rod 7011 forward and make the right inner nozzle 702 and the right outer nozzle 703 spray oil. When the upper right roller 8021 leaves, the piston rod 7011 can move backward to reset and stop the right inner nozzle 702 and the right outer nozzle 703 from spraying oil.The frame 1 of this invention is equipped with mechanical oil spraying devices on the left and right sides, respectively, and the oil spraying is achieved by mechanically driving the rotating arm. It does not require electricity or electronic devices such as metal sensors. It can be powered by the pushing force of the operator on the pusher frame 3 or the pulling force of other rail vehicles on the traction hook 2, so that the equipment can work normally without electricity. It has high reliability during long-term continuous operation, is easy and simple to operate, and can be used for a long time along the railway line in the field without accidental oil spraying. When moving, it can automatically and accurately spray oil on the rail fasteners, which can effectively avoid oil waste and reduce the environmental pollution caused by oil. By spraying oil on the rail fasteners, it can effectively prevent the fasteners from rusting and extend their service life. In use, the operator places the device on the left and right rails 9, with the front rail wheel 4 and rear rail wheel 5 secured to the rails. The device is then pushed forward by the pusher frame 3 or pulled forward by other rail vehicles via the traction hook 2. When it reaches the rail fastener 10, the rail fastener 10 causes the lower end of the right drive arm 8 to deflect backward, allowing the upper right roller 8021 to push the piston rod 7011 forward. The right inner fastener nozzle 702 and the right outer fastener nozzle 703 spray oil onto the rail fastener 10. When the rail fastener 10 leaves the lower end of the right drive arm 8, the piston rod 7011 automatically moves backward to reset and stops spraying oil, achieving "pass-through spraying." This eliminates the need to stop the device or tighten / loosen bolts, greatly improving oiling efficiency and work quality. The device is safe, labor-saving, simple, and highly efficient.

[0021] Example 2:

[0022] As attached Figure 1-3 As shown, the difference between this embodiment and Embodiment 1 is that the lower end of the right arm vertical rod 801 is provided with a pivot and a lower right roller 8022 is installed. The lower right roller 8022 enables the track fastener 10 to push the drive arm to deflect more smoothly, and allows the lower end of the right arm vertical rod 801 to roll on the upper end of the track fastener 10 via the lower right roller 8022, driving the mechanical oil spraying device to spray oil onto the track fastener 10 smoothly without jamming. When the lower end of the right arm vertical rod 801 falls from the upper end of the track fastener 10, it rolls down more smoothly via the lower right roller 8022, reducing the accidental swing amplitude of the right arm vertical rod 801.

[0023] Example 3:

[0024] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1 and 2 is that the right injector 701 includes an injector housing 7012, a connecting seat 7013, a fuel injection cylinder 7014, a fuel injection check valve 7015, and a fuel injection check valve 7016. The injector housing 7012 has a housing frustum 70120 at its rear end. The connecting seat 7013 is fixedly installed on the rear part of the injector housing 7012. The connecting seat 7013 is fixedly installed on the right transverse frame 101. The upper rear end of the housing frustum 70120 has a fuel injection valve seat hole 70121 and a fuel injection check valve 7015 is installed thereon. The fuel injection check valve 7015 is connected to the fuel tank 6 through a fuel supply pipe 704 and can deliver fuel to the fuel injection cylinder 7014. The lower rear end of the housing frustum 70120 has a cylinder seat hole 70122 and a fuel injection cylinder 7014 is installed thereon. A piston push rod 701... Located on the fuel injection cylinder 7014, the piston push rod 7011 can open the fuel injection check valve 7016 and supply fuel to it when moving forward, and open the fuel intake check valve 7015 when moving backward to draw fuel from the fuel tank 6 into the fuel injection cylinder 7014. The lower front end of the injector housing 7012, corresponding to the central axis position of the cylinder seat hole 70122, is provided with a fuel injection valve seat hole 70123 and is equipped with a fuel injection check valve 7016. The fuel injection check valve 7016 is connected to the right inner nozzle 702 and the right outer nozzle 703 via the oil outlet pipe 705, enabling fuel injection. The oil intake valve seat hole 70121 is connected to the cylinder seat hole 70122 and the fuel injection valve seat hole 70123 via the vertical cavity hole 70124. The injector housing 7012 at the upper end of the vertical cavity hole 70124 is provided with a sealing thread and a cavity pin 7017 is fixedly installed. By installing the cavity pin 7017, the vertical cavity hole 70124 can be kept sealed. The vertical cavity hole 70124 can connect the fuel intake cylinder 7014, the fuel intake check valve 7015, and the fuel injection check valve 7016, while the manufacturing process is relatively simple.

[0025] Example 4:

[0026] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1-3 is that the oil injection cylinder 7014 includes a cylinder sleeve 70141, a piston rod assembly, and a push spring 70145. The outer side of the cylinder sleeve 70141 is fixedly installed in the cylinder seat hole 70122 by threads. The piston rod assembly that can slide back and forth is fitted inside the inner cavity of the cylinder sleeve 70141. The rear part of the inner wall of the cylinder sleeve 70141 is threaded and fixedly installed with a piston retaining ring 70146. The front end of the piston push rod 7011 is fixed or connected to the rear end of the piston rod assembly. The front end of the piston rod assembly is directly opposite the rear end of the injection valve seat hole 70123 and can move forward to open the injection check valve 7016. The front part of the piston rod assembly is equipped with a push spring 70145, and the front end of the push spring 70145 is pressed against the front side wall of the vertical cavity hole 70124. The drive arm can push the piston push rod 7011, causing the piston rod assembly to move forward within the cylinder liner 70141 and open the fuel injection check valve 7016, thereby enabling the fuel injection check valve 7016 to inject fuel. When the drive arm leaves the piston push rod 7011, the push spring 70145 can cause the piston rod assembly to move backward and reset, thereby enabling the intake of fuel.

[0027] Example 5:

[0028] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1-4 is that the piston-rod assembly includes a suction-jet piston 70142, a disc-head push rod 70143, and a piston spring 70144. The suction-jet piston 70142 is fitted inside the cylinder liner 70141, and the rear end of the suction-jet piston 70142 is pressed against the front end of the piston retaining ring 70146. The front end of the piston push rod 7011 is integrated with the center of the rear end of the suction-jet piston 70142. The suction-jet piston 70142 has a piston chamber with an opening facing forward and is equipped with a piston spring 70144. The elastic force of the piston spring 70144 is less than that of the push spring 70145. The opening of the piston chamber has a conical surface that is larger at the front and smaller at the back. The disc-head push rod 70143 includes a push plate 701431 and a push rod 70144. The push rod 701432 has its rear end integrated with the front center of the push plate 701431. The push plate 701431 has an oil passage hole 701433. The outer side of the push plate 701431 is a disc head cone surface that matches the cone surface of the piston cavity. The push plate 701431 is fitted into the cone surface of the piston cavity through the disc head cone surface. The front end of the piston spring 70144 is pressed against the rear end of the push plate 701431, and the rear end of the piston spring 70144 is pressed against the inner wall of the rear end of the piston cavity. The front end of the push rod 701432 is directly opposite the center of the rear end of the fuel injection valve seat hole 70123. The push spring 70145 is fitted on the outer side of the push rod 701432, and the rear end of the push spring 70145 is pressed against the front side of the push plate 701431. By setting a piston chamber inside the pumping piston 70142 and installing a piston spring 70144, and setting a pan head push rod 70143 separate from the pumping piston 70142, the oil pressure impact when the pumping piston 70142 moves can be reduced. In actual manufacturing, the number of oil passage holes 701433 is not less than one. When the pumping piston 70142 moves, the oil in the inner cavity of the cylinder liner 70141 can slowly enter the piston chamber of the pumping piston 70142 or slowly flow out of the piston chamber of the pumping piston 70142 through the oil passage hole 701433, thus further effectively reducing the oil pressure fluctuation or impact caused by the movement of the pumping piston 70142.

[0029] The fuel injection check valve 7016 includes a fuel injection valve body 70161, a fuel injection valve cover 70162, a fuel injection valve spring 70163, and a fuel injection valve ball 70164.

The diameter of the rear end of the fuel injection cone surface 70165 is larger than the outer diameter of the push rod column 701432. The fuel injection valve body 70161 has a through fuel injection valve hole, and the inner diameter of the fuel injection valve hole is larger than the diameter of the fuel injection valve ball 70164. A valve hole annular platform is provided on the inner wall of the middle part of the fuel injection valve hole. The fuel injection valve spring 70163 is installed in the fuel injection valve hole behind the valve hole annular platform. The rear end of the fuel injection valve spring 70163 presses against the fuel injection valve ball 70164, and the rear end of the fuel injection valve ball 70164 is pressed against the fuel injection cone surface 70165. The front part of the fuel injection valve body 70161 is fixedly installed with a fuel injection valve cover 70162 by threads. The front end of the fuel injection valve cover 70162 is provided with a core hole and is fitted with an oil outlet pipe 705. The oil outlet pipe 705 is pressed and fixed to the rear end of the fuel injection valve body 70161 by the fuel injection valve cover 70162. The inner cavity of the oil outlet pipe 705 is connected to the fuel injection valve hole through the core hole of the fuel injection valve cover 70162. The diameter of the rear end of the injection cone 70165 is larger than the outer diameter of the push rod 701432, allowing the push rod 701432 to enter the inner cavity of the injection cone 70165 and push the injection valve ball 70164. The inner diameter of the injection valve hole is larger than the diameter of the injection valve ball 70164, allowing the pushed injection valve ball 70164 to compress the injection valve spring 70163 and enter the injection valve hole, thereby opening the one-way injection valve 7016 to achieve fuel injection.

[0030] Example 6:

[0031] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1-5 is that the oil-drawing one-way valve 7015 includes an oil-drawing valve body 70151, an oil-drawing valve cover 70152, an oil-drawing valve spring 70153, an oil-drawing valve ball 70154, and a valve spring top sleeve 70155. The front part of the oil-drawing valve body 70151 is fixedly installed in the oil-drawing valve seat hole 70121 by threads, and the oil-drawing valve cover 70152 is fixedly installed on the outer side of the rear part of the oil-drawing valve body 70151 by threads. The rear end of the oil-drawing valve cover 70152 has a core hole and is fitted with an oil supply pipe 704. The oil supply pipe 704 is pressed and fixed to the rear of the oil-drawing valve body 70151 by the oil-drawing valve cover 70152. At the end, the front end of the oil-drawing valve body 70151 is provided with a threaded countersunk hole and a valve spring top sleeve 70155 is fixedly installed. The bottom of the threaded countersunk hole is provided with an oil-drawing valve hole. The oil-drawing valve hole includes a valve hole large diameter section, a valve core cone surface that is larger at the front and smaller at the back, and a valve hole small diameter section connected from front to back. An oil-drawing valve spring 70153 and an oil-drawing valve ball 70154 are installed in the valve hole large diameter section. The valve spring top sleeve 70155 presses the oil-drawing valve ball 70154 through the oil-drawing valve spring 70153 and makes the rear part of the oil-drawing valve ball 70154 press against the valve core cone surface. The rear end of the valve hole small diameter section is connected to the inner cavity of the oil supply pipe 704 through the core hole of the oil-drawing valve cover 70152. The valve spring top sleeve 70155 can be used to adjust the compression of the oil-drawing valve spring 70153, thereby adjusting the clamping force of the oil-drawing valve spring 70153 on the oil-drawing valve ball 70154, that is, adjusting the opening oil pressure difference of the oil-drawing check valve 7015, so that the amount of oil drawn into the oil-drawing injection cylinder 7014 can be adjusted as needed, which makes it more convenient to use.

[0032] During operation, when the lower end of the drive arm contacts the track fastener 10, the upper part of the drive arm pushes the piston rod 7011 forward and drives the right injector 701 to work. The piston rod 7011 drives the injection piston 70142 forward. The injection piston 70142 drives the push rod column 701432 forward through the push plate 701431 of the pan head push rod 70143, overcoming the elastic force of the push spring 70145. The injection piston 70142 increases the oil pressure inside the cylinder liner 70141 and the vertical cavity 70124, thus increasing the oil pressure. With valve 7015 closed, the front end of push rod 701432 gradually extends into the injection cone 70165 cavity, pushing the injection valve ball 70164 forward, causing the injection valve ball 70164 to leave the injection cone 70165. The injection check valve 7016 opens, and as the suction piston 70142 continues to move forward, the pressurized oil in the inner cavity of cylinder liner 70141 and vertical cavity 70124 is forced out and transported to the track fastener by oil outlet pipe 705, three-way connector 7051, right inner buckle nozzle 702, and right outer buckle nozzle 703. As the present invention continues to move forward, the drive arm disengages from the track fastener 10 and the rear end of the piston push rod 7011. The push spring 70145, due to its own elasticity, pushes the disc head push rod 70143 and the injection piston 70142 back to their original positions. During the return stroke of the injection piston 70142, the injection valve spring 70163, due to its own elasticity, pushes the injection valve ball 70164 to press against the injection cone surface 70165 again, causing the injection check valve 7016 to close. The right inner nozzle 702 and the right outer nozzle 703 stop injecting oil. Simultaneously, the injection piston 70142... During the backward movement, the interior of the vertical cavity 70124 becomes a negative pressure space. The oil in the oil supply pipe 704, which is connected to the oil tank 6, moves forward due to the oil pressure difference, pushing the oil suction valve ball 70154 to overcome the elastic force of the oil suction valve spring 70153. This causes the oil suction check valve 7015 to open. The oil suction check valve 7015 draws in oil again through the oil supply pipe 704 and sends it to the vertical cavity 70124 and the inner cavity of the cylinder liner 70141 for storage, waiting for the drive arm to contact the next track fastener again. In this way, the oil tank 6 continuously supplies oil through the right injector 701.

[0033] Example 7:

[0034] As attached Figure 1-3As shown, the difference between this embodiment and embodiments 1-6 is that the right arm vertical rod 801 is hinged to the right transverse frame 101 via the right arm hinge pin 803. A damping return device 11 is provided on the right transverse frame 101 below the right arm hinge pin 803. The damping return device 11 includes a return seat plate 1101, a front spring upright plate 1102, a rear spring upright plate 1103, a front return spring 1104, and a rear return spring 1105. The return seat plate 1101... The right transverse frame 101 is welded and fixed to the bottom right end of the right transverse frame 101. The front and rear ends of the return plate 1101 are welded with a front spring plate 1102 and a rear spring plate 1103, respectively. The ends of the front return spring 1104 and the rear return spring 1105 that are far apart are fixed to the front spring plate 1102 and the rear spring plate 1103, respectively. The ends of the front return spring 1104 and the rear return spring 1105 that are close to each other are fixed to the front and rear sides of the right arm vertical rod 801, respectively. The damping return device 11 allows the right arm vertical rod 801 to return to the vertical position promptly after leaving the track fastener 10, preventing it from swinging back and forth due to inertia. This ensures that the upper right roller 8021 leaves the piston push rod 7011 in time, avoiding oil waste caused by accidental oil injection. Furthermore, a limiting pin 12 can be installed on the right transverse frame 101 to limit the maximum tilt position of the right arm vertical rod 801, protecting the right injector 701.
