Description

Technical Field

[0001] This invention belongs to the technical field of track protective film coating devices, and relates to a non-powered track coating machine. Background Technology

[0002] Train tracks are in constant contact with train wheels, causing severe wear on the track surface. Applying a protective film to the upper and inner surfaces of the rails can greatly reduce wheel-rail wear, thereby extending the service life of the rails. Therefore, track protective film coating equipment is needed.

[0003] Existing track coating equipment mainly relies on solar cells or other large batteries for power, driving motors to operate oil pumps. The problem with this equipment is that solar cells are affected by weather, resulting in significant issues with battery life. If other large batteries are used for power, there are environmental problems and safety issues related to the absence of large obstacles on both sides of the track. Summary of the Invention

[0004] The purpose of this invention is to provide a non-powered track coating machine that solves the problems of existing track coating equipment relying on solar cells for poor battery life and other large batteries for power, which affects the safety of both sides of the track.

[0005] The technical solution adopted in this invention is a non-powered track coating machine, including a trigger conversion device, a self-resetting plunger pump, a hydraulic motor, a retractable spline shaft, a lead screw, and a storage tank. The trigger conversion device is directly opposite the free end face of piston I of the self-resetting plunger pump. The oil outlet of the self-resetting plunger pump is connected to the oil inlet of the hydraulic motor through an oil pipe. The output shaft of the hydraulic motor is connected to the retractable spline shaft. The retractable spline shaft and the lead screw are connected through an electromagnetic clutch. The storage tank contains piston II and a capsule-shaped coating film plastic tank. Piston II is installed at the end of the lead screw. The capsule-shaped coating film plastic tank is located between piston II and the inner wall of the storage tank. A copper nut is installed on the outer side wall of the storage tank. The lead screw is threadedly connected to the copper nut. The discharge port of the capsule-shaped coating film plastic tank and the discharge port of the storage tank are connected.

[0006] The trigger conversion device includes a pressure rod, a guide rail II, and a right-angled trapezoidal bracket. The pressure rod consists of a vertical rod, a horizontal rod, an inclined rod, and a slider I connected and fixed in sequence. The horizontal rod is fixed in the middle of the vertical rod. The right-angled trapezoidal bracket has through holes at the top and bottom that allow the vertical rod to pass through. The right-angled trapezoidal bracket is located at the top of the guide rail II. The slider II is installed at the bottom of the right-angled trapezoidal bracket and is located in the middle of the guide rail II. The guide rail I is fixed on the inclined surface of the right-angled trapezoidal bracket. Supports are fixed on the bottom of the slider I on opposite sides. The support has grooves on its bottom surface, and the guide rail I is located in the grooves of the support. Two clamping plates are provided on the side of the right-angled trapezoidal bracket opposite to the inclined surface. The free end of the piston I is located between the two clamping plates.

[0007] It also includes a lifting device, which consists of a stepped bracket, a miniature electric cylinder, and a support. The stepped bracket is composed of a vertical plate, a bottom plate, and a top plate. The bottom plate and the top plate are located on opposite sides of the vertical plate. The guide rail II is fixed to the bottom plate with bolts. The telescopic rod of the miniature electric cylinder is fixedly connected to the top plate. The miniature electric cylinder is installed on the support. Two rows of vertical guide rails III are provided on the side of the support. The miniature electric cylinder is located between the two rows of guide rails III. A slider III that cooperates with the guide rails III is installed on the side of the vertical plate.

[0008] Rib plate I is provided between the upright plate and the bottom plate of the stepped bracket.

[0009] A horizontal pressure plate is fixed on the vertical rod of the pressure bar. The horizontal pressure plate is located at the bottom of the horizontal rod. A laser counter is installed on the bottom plate of the stepped bracket. The laser counter faces the horizontal pressure plate and is electrically connected to the electromagnetic clutch.

[0010] A worm gear reducer is connected between the hydraulic motor and the retractable spline shaft.

[0011] A one-way valve I is installed in the middle of the oil pipe.

[0012] The self-resetting plunger pump includes a pump body, pump cover, piston I, plunger, cylinder, return spring, and control valve. One end of piston I is located inside the pump body cavity, and the other end is located outside the pump body. The plunger is installed inside the pump body cavity, and the cylinder is sleeved on the plunger. The pump body cavity is a two-step bore, with the inner diameter of the first-step bore being larger than that of the second-step bore. One end of the cylinder is installed inside the second-step bore and threaded to the inner wall of the second-step bore, while the other end is located inside the first-step bore. The return spring is sleeved on the cylinder and the plunger, and a spring seat is sleeved at the junction of the plunger and piston I. The pump body has an oil inlet and an oil outlet. The control valve is located between the oil inlet and the oil outlet, and a three-way oil passage is opened inside the control valve. One end of the three-way oil passage is connected to the pump body cavity, and the other two ends are connected to the oil inlet and the oil outlet, respectively. A one-way valve II is installed between the oil inlet and the control valve.

[0013] The plunger has a through hole inside, and a safety valve is installed in the through hole. The piston I has an oil passage A connected to the through hole, and the outlet of oil passage A is connected to the oil tank inlet through a pipe.

[0014] The oil inlet is connected to the oil tank outlet via an oil pipe. The oil outlet, hydraulic motor return port, and drain port are all connected to the oil tank inlet via pipes.

[0015] The beneficial effects of this invention are that the pressure of the wheel is converted into a horizontal driving force by the trigger conversion device, which drives the self-resetting plunger pump to work. The self-resetting plunger pump outputs high-pressure hydraulic oil, which is injected into the hydraulic motor to drive its output shaft to rotate at high speed, thereby driving the retractable spline shaft and the lead screw to rotate, causing piston II to move to the right, compressing the capsule-shaped coating film plastic can, and extruding the coating film in the can to coat the track surface. This coating machine does not require electric drive, is energy-saving and environmentally friendly, does not require a large battery, and does not affect the safety of both sides of the track. It has a simple structure, small size, and the trigger conversion device is touch-activated, so there is no waste of protective film material. Attached Figure Description

[0029] Example 1

[0030] A non-powered track coating machine, referring to Figure 1 and Figure 2 The system includes a trigger conversion device 9, a self-resetting plunger pump 8, a hydraulic motor 6, a retractable spline shaft 3, a lead screw 14, and a storage tank 1. The trigger conversion device 9 is directly opposite the free end face of the piston I 81 of the self-resetting plunger pump 8. The oil outlet of the self-resetting plunger pump 8 is connected to the oil inlet of the hydraulic motor 6 through an oil pipe 7. A one-way valve I 71 is installed in the middle of the oil pipe 7. The output shaft of the hydraulic motor 6 is connected to the retractable spline shaft 3. The retractable spline shaft 3 is connected to the lead screw 14 through an electromagnetic clutch 2. The storage tank 1 is equipped with... The system includes a piston II 13 and a capsule-shaped coated plastic container. The outlet of the capsule-shaped coated plastic container is connected to the outlet of the storage tank 1. The piston II 13 is mounted at the end of the lead screw 14. The capsule-shaped coated plastic container is located between the piston II 13 and the inner wall of the storage tank 1. A copper nut 15 is installed on the outer side wall of the storage tank 1. The lead screw 14 is threadedly connected to the copper nut 15. When the lead screw 14 rotates, it drives the piston II to move to the right. The piston II compresses the capsule-shaped coated plastic container, thereby extruding the coated film and coating it onto the track surface. (See [reference]). Figure 3 .

[0031] Reference Figure 4 and Figure 5The trigger conversion device 9 includes a pressure rod 91, a guide rail II 92, and a right-angled trapezoidal bracket 93. The pressure rod 91 consists of a vertical rod, a horizontal rod, an inclined rod, and a slider I 99 connected and fixed in sequence. The horizontal rod is fixed in the middle of the vertical rod. The right-angled trapezoidal bracket 93 has through holes at the top and bottom that allow the vertical rod to pass through. The right-angled trapezoidal bracket 93 is located at the top of the guide rail II 92. A slider II 98 is installed at the bottom of the right-angled trapezoidal bracket 93 and is located in the middle of the guide rail II 92. A guide rail I 97 is fixed on the inclined surface of the right-angled trapezoidal bracket 93. Supports 95 are fixed on the bottom of the slider I 99 on opposite sides. A groove is opened on the bottom surface of the support 95. The guide rail I 97 is located in the groove of the support 95. Two clamping plates 96 are provided on the side of the right-angled trapezoidal bracket 93 opposite to the inclined surface. The free end of the piston I 81 is located between the two clamping plates 96.

[0032] When the wheel passes the top of the trigger conversion device 9, the wheel pressure drives the pressure rod 91 to move down, which in turn moves the right-angle trapezoidal bracket 93 toward the piston I, pushing the piston I into the inner cavity of the self-resetting plunger pump 8. This forces the hydraulic oil in the pump body into the hydraulic motor 6, which then rotates and outputs torque, which is transmitted to the telescopic spline shaft. The telescopic spline shaft then transmits the torque to the electromagnetic clutch, which in turn drives the lead screw to rotate. The lead screw pushes the piston II to squeeze the capsule-shaped coated plastic can inside the storage tank, thereby extruding the coated film.

The plunger 86 is installed inside the pump body 83, and the cylinder 87 is sleeved on the plunger 86. The inner cavity of the pump body 83 is a two-step bore, with the inner diameter of the first step bore being larger than that of the second step bore. One end of the cylinder 87 is installed inside the second step bore and threaded to the inner wall of the second step bore, and the other end... Located within the first-step bore, a return spring 85 is sleeved on the cylinder 87 and the plunger 86. A spring seat 84 is sleeved at the junction of the plunger 86 and the piston I 81.

A one-way valve II 89 is provided between the oil inlet 810 and the pilot valve 88.

[0048] Reference Figure 11 The plunger 86 has a through hole inside, in which a safety valve 812 is installed. The piston I 81 has an oil passage A connected to the through hole, and the outlet of oil passage A is connected to the oil inlet of the oil tank 10 via a pipe. The through hole is a three-stage hole. The first stage hole connects to the oil passage in the piston. The inner diameters of both the first and third stage holes are larger than the inner diameter of the second stage hole. The safety valve is installed in the first stage hole and consists of a perforated screw, a miniature spring, a copper sleeve A, and a steel ball A arranged in sequence.

[0052] When the train wheel passes the trigger conversion device, the device converts the downward pressure of the wheel into a horizontal driving force, driving piston I to move into the pump body cavity. This causes the plunger to move inward, expelling the air from the pump body cavity. After the external force is eliminated, the return spring drives the plunger to return to its original position, making the air pressure in the pump body cavity negative. This allows hydraulic oil from the oil tank to enter the pump body cavity through the inlet. When the external force drives the piston to move inward again, the plunger moves inward, expelling the hydraulic oil from the pump body cavity through the outlet and injecting it into the hydraulic motor, thus driving the hydraulic motor to work.

[0053] The non-powered track coating machine also includes an infrared sensor 11, which consists of an infrared transmitter and an infrared receiver. The infrared transmitter is fixed to the bottom surface of the electromagnetic clutch 2, and the infrared receiver is located at the bottom of the electromagnetic clutch 2. The infrared receiver is electrically connected to the electromagnetic clutch 2. The horizontal distance between the infrared receiver and the inner right wall of the storage tank 1 is equal to the sum of the length of the lead screw 14 and the thickness of the capsule-shaped coating film plastic tank after it is fully compressed. After the material in the capsule-shaped coating film plastic tank is completely squeezed out, the infrared receiver detects the signal of the electromagnetic clutch 2 passing through, causing the electromagnetic clutch 2 to disengage, thus reminding the operator to add oil to the tank.

[0054] The working principle of the non-powered track coating machine of this invention is as follows:

[0055] When a train wheel passes the trigger conversion device, the device converts the downward pressure of the wheel into a horizontal driving force, which drives the self-resetting plunger pump to work and output high-pressure hydraulic oil. The hydraulic oil is injected into the hydraulic motor, and the hydraulic motor rotates to output torque. After the torque is reduced and increased by the worm gear reducer, it is output to the telescopic spline shaft. The telescopic spline shaft transmits the torque to the electromagnetic clutch. The electromagnetic clutch drives the lead screw to rotate, and the lead screw pushes the piston II to squeeze the capsule-shaped plastic container of the storage tank, thereby extruding the coating film and coating it onto the wheel and rail surface.
