Description

Technical Field

[0001] This invention relates to the technical field of transformer relocation, and more particularly to a track-mounted wheel set suitable for transformer relocation. Background Technology

[0002] In recent years, the main transformers of large power plants are generally large in size and heavy in weight. During installation and maintenance, there is a transfer process from the work site to the maintenance workshop. Due to the large size and heavy weight of the main transformer and the limited space in the station, the entire transfer process is quite difficult. Generally, a winch is used for external dragging or a wheeled unit with self-propelled capability is used for transportation. Both methods have certain drawbacks.

[0003] Currently, most self-propelled wheel sets use a combination of motor and reducer. When a larger output torque is required, an additional multi-stage transmission gear set is needed, which further increases the overall size and limits its use. Moreover, the reducer housing has limited load-bearing capacity. To meet the load-bearing requirements under high load conditions, the side-mounted motor and reducer will increase material costs and the overall size of the equipment. Furthermore, the wheels are relatively brittle and are easily damaged when they come into contact with sand or gravel during track travel, resulting in a short service life. Summary of the Invention

[0004] Given that most existing self-propelled wheel sets use a combination of motor and reducer, additional multi-stage transmission gear sets are required when a large output torque is needed, resulting in large size and limited use. Moreover, the reducer housing has limited load-bearing capacity. To meet the load-bearing requirements under high load conditions, the side-mounted motor and reducer configuration will increase material costs and the overall size of the equipment. Furthermore, the wheels are relatively brittle and easily damaged when in contact with sand or gravel during track travel, resulting in a short service life. Therefore, this invention is proposed.

[0038] Example 1

[0039] Reference Figures 1-6 The first embodiment of the present invention provides a track-mounted wheel assembly suitable for transformer transportation, the device comprising:

[0040] The walking mechanism 100 includes a wheel frame 101, a power component 102, an auxiliary component 103, and an eccentric support component 104. The power component 102 and the auxiliary component 103 are respectively installed on both sides of the inner cavity of the wheel frame 101, and the eccentric support component 104 is located on the side biased towards the auxiliary component 103.

[0041] Among them, the bearing material in auxiliary component 103 is 40Cr, and the material stress is 785MPa; the wheel frame 101 is made of low alloy material Q355 welded together.

[0042] The cleaning mechanism 200 includes a quick-release component 201 fixedly installed on the outer side of the wheel frame 101, a support frame 202 snapped and fixed to the quick-release component 201, a dust removal component 203 installed on the inner side of the support frame 202, a mud and dirt collection component 204 and a maintenance component 205 adapted to be installed on the outer side of the dust removal component 203, and a sand and gravel collection component 206 fixedly installed on the outer side of the maintenance component 205. The maintenance component 205 is installed at the bottom of the mud and dirt collection component 204.

[0043] Furthermore, the power assembly 102 includes a drive wheel 102a, a hydraulic motor reducer assembly 102b, an encoder mounting plate 102c, and a grating rotary encoder 102d. The drive wheel 102a and the hydraulic motor reducer assembly 102b are connected and fastened together by hexagonal screws in a nested manner, making them integrated into one unit. The grating rotary encoder 102d is fixed to the hydraulic motor reducer assembly 102b by the encoder mounting plate 102c. The auxiliary assembly 103 includes a driven wheel 103a. The driven wheel axle 103b and the driven wheel 103a are fixedly mounted on the wheel set frame 101 via the driven wheel axle 103b and a nut; the eccentric support assembly 104 includes a spreader beam axle 104a, a beam frame 104b, a cylinder cover plate 104c and a floating cylinder 104d. The spreader beam axle 104a and the beam frame 104b are movably mounted on the wheel set frame 101 by screws. The cylinder cover plate 104c is fixedly mounted on the top of the beam frame 104b. The cylinder body of the floating cylinder 104d is fixed to the cylinder cover plate 104c by welding.

[0044] In addition, considering the unevenness of the track surface during the journey, a floating hydraulic cylinder 104d is installed on the device. When the track surface is high, the hydraulic cylinder piston rod retracts, and when the ground is low, the hydraulic cylinder piston rod extends, ensuring that the traveling mechanism 100 is always in pressure contact with the track.

[0045] Among them, the hydraulic pump is driven by a variable frequency motor to generate fluid force to drive the hydraulic motor reducer assembly 102b. The hydraulic system is mainly composed of a hydraulic power source device consisting of an electric motor, hydraulic pump, oil tank, electric control valve, throttle valve, relief valve, accumulator, etc. It includes a hydraulic power source system, control system, safety system, heat dissipation system, cleaning and filtration system, etc. The hydraulic system is designed with flow, pressure and flow direction control according to the requirements of the actuator device. It is suitable for various machines where the load device and hydraulic station are separated. By connecting the hydraulic station and the drive device (cylinder or motor) with oil pipes, the hydraulic system can realize various specified actions and purposes.

[0046] Preferably, by utilizing the lever principle of a spreader beam, the load-bearing capacity of the two wheels in the traveling mechanism 100 is distributed differently, allowing more load to be distributed to the driven wheel 103a. Taking a single wheel set bearing 50T as an example, the force-bearing center axis of the wheel set is biased towards the driven wheel 103a. Therefore, it can be ensured that the power component 102 always bears only 20T under the effect of eccentricity, while the driven wheel bears 30T of force. This design effectively solves the problem of the limited load-bearing capacity of the entire wheel set caused by the load-bearing capacity limitation of the hydraulic motor itself, breaks through the upper limit of the load-bearing capacity of the integrated power component 102, and increases the upper limit of the load-bearing capacity of the wheel set while reducing the size of the wheel set.

[0047] It should be noted that the four independent walking mechanisms 100 of this invention are combined into a four-wheel drive system, and each walking mechanism 100 is individually controlled to achieve controllable and adjustable speed of a single walking wheel set. A grating rotary encoder 102d is equipped on the power assembly 102 to achieve high speed control accuracy. Simultaneously, the control system enables closed-loop feedback synchronous control of the four-wheel drive wheel sets, achieving synchronized movement, greatly increasing the output torque of the walking equipment and improving passability. This design effectively solves the problem of insufficient obstacle-crossing ability or slippage leading to insufficient passability for most walking wheel sets. Furthermore, the individual hydraulic control of the four-wheel drive system enables differential movement of each wheel set, solving the problems of vehicle deviation and rail collision / rail wear caused by asynchrony between wheel sets during travel.

[0048] In summary, the hydraulic motor and reducer assembly 102b integrates the motor, reducer, and traveling wheels into one unit, greatly reducing the size of the device and enabling the mobile equipment to operate in a very small space. The traveling wheel set adopts a front and rear dual-wheel structure with an eccentric load support design, which shifts the load support center axis toward the load-bearing driven wheel 103a without a hydraulic motor. By utilizing the lever principle of the spreader beam axle 104a, the load-bearing capacity of the two wheels in the traveling mechanism 100 is distributed differently, allowing more load to be distributed to the driven wheel 103a, exceeding the upper limit of the hydraulic motor's load-bearing capacity, and increasing the upper limit of the wheel set's load-bearing capacity while reducing the wheel set's size.

[0049] Example 2

[0050] Reference Figure 1 , Figure 7 , Figure 8 and Figure 13 This is the second embodiment of the present invention, which differs from the first embodiment in that a cleaning mechanism 200 is installed on one side of the walking mechanism 100 using a quick-release part 201.

[0051] Furthermore, the quick-release component 201 includes two snap-fit ​​boxes 201a fixedly mounted on the outer surface of the wheel set frame 101, and a threaded pin 201b threadedly connected to the top of the snap-fit ​​box 201a. One end of the support frame 202 is inserted into the inner cavity of the snap-fit ​​box 201a and fixed by the threaded pin 201b.

[0052] Furthermore, the dust removal component 203 includes a transmission rod 203a disposed inside the support frame 202, a wheel 203b fixedly sleeved on the middle section of the outer surface of the transmission rod 203a, a soft bristle cleaning sleeve 203c bonded to the outer surface of the wheel 203b, a drive gear roller 203d fixedly sleeved on one side of the outer surface of the transmission rod 203a, a rack and belt 203e meshing with the outer surface of the drive gear roller 203d, and the other end of the rack and belt 203e... The driven gear roller 203f engages with the wall; the sludge collection component 204 includes a dust collection box 204a fixedly mounted to the support frame 202, a feed inlet 204b opened on the side of the dust collection box 204a near the dust cleaning component 203, a scraper 204c fixedly mounted on the outside of the feed inlet 204b, and scraper teeth 204d fixedly mounted on the upper end of the scraper 204c. Both the scraper 204c and the scraper teeth 204d are in contact with the outer surface of the soft bristle cleaning sleeve 203c.

[0053] The walking mechanism 100 is placed on the track, with the lowest point of the wheel 203b slightly higher than the track height. The soft bristle cleaning sleeve 203c is designed to rub and deform when in contact with the track, cleaning the sand, dust, and rust on the track surface. The scraper 204c and scraper teeth 204d can scrape off the sand, dust, and rust carried by the soft bristle cleaning sleeve 203c. The sand, dust, and rust can enter the dust collection box 204a through the feed inlet 204b.

[0054] Specifically, the sand and gravel collection component 206 includes a support member 206a fixedly connected to the outer surface of the support frame 202, a sand and gravel box 206b fixedly connected to the support member 206a, and a stepped collection plate 206c fixedly installed on the outer surface of the sand and gravel box 206b and communicating with its interior.

[0055] The lowest point of the stepped collection plate 206c is slightly higher than the track height, allowing fine sand and gravel to pass through the gaps. During the movement of the device, the stepped collection plate 206c exerts a pushing force on larger sand and gravel particles. Some of the sand and gravel will flip upwards along the stepped collection plate 206c and enter the sand and gravel box 206b, while some larger particles may remain on the surface of the stepped collection plate 206c. All of this can prevent the traveling mechanism from contacting larger sand and gravel particles.

[0056] In use, the hydraulic motor reducer assembly 102b provides rotational power to the drive wheel 102a. The drive wheel 102a rotates to drive the walking mechanism 100 to move. The walking mechanism 100 drives the cleaning mechanism 200 to move as a whole. The soft bristle cleaning sleeve 203c can rotate with it and rubs and deforms when it contacts the track.

[0057] In summary, the soft bristle cleaning sleeve 203c is designed to generate friction and deformation upon contact with the track, cleaning and collecting small grit, dust, and rust from the track surface. The stepped collection plate 206c exerts a pushing force on larger grit particles, causing some of the grit to flip upwards along the stepped collection plate 206c and enter the sand and gravel box 206b. This effectively cleans the grit, dust, and rust adhering to the track surface, improves the passability of the traveling mechanism 100 on the track surface, and effectively extends the service life of the wheel set.

[0058] Example 3

[0059] Reference Figure 1 , Figures 7-12 This is the third embodiment of the present invention, which differs from the second embodiment in that a maintenance component 205 is added to comb the soft bristle cleaning sleeve 203c.

[0060] Specifically, the maintenance component 205 includes a housing 205a fixedly installed at the bottom of the dust collection box 204a, a fluffing component 205b disposed on the side of the housing 205a near the dust cleaning component 203, an oil supply component 205c fixedly installed at the top of the inner cavity of the housing 205a, a first transmission component 205d connected to the driven gear roller 203f, and a second transmission component 205e disposed in the inner cavity of the housing 205a.

[0061] The first transmission component 205d is used to drive the fluffing component 205b to reciprocate; the second transmission component 205e is used to control the intermittent oil supply of the oil supply component 205c.

[0062] Specifically, the fluffing component 205b includes a brush plate 205b-1 disposed between the housing 205a and the soft bristle cleaning sleeve 203c, a plurality of brush needles 205b-2 communicating with the brush plate 205b-1 and fixed on one side of its surface, and guide posts 205b-3 slidably connected to the outer surface of the housing 205a and fixedly connected to the brush plate 205b-1.

[0063] The brush plate 205b-1 has an arc-shaped hollow structure. The front end of the brush needle 205b-2 has several fine holes. The front end of the brush needle 205b-2 is inserted into the soft bristle cleaning sleeve 203c. Lubricating oil can flow into the interior of the brush plate 205b-1 through the hose 205c-5, then enter the brush needle 205b-2 through the brush plate 205b-1, and finally seep out from the fine holes on its surface and be absorbed by the bristle end of the soft bristle cleaning sleeve 203c.

[0064] Furthermore, the oil supply assembly 205c includes a lubricating oil box 205c-1 fixedly installed on the top of the inner cavity of the housing 205a, an oil pipe 205c-2 communicating with the lubricating oil box 205c-1, a valve 205c-3 installed on the outer surface of the oil pipe 205c-2, a return spring 205c-4 provided at the valve handle of the valve 205c-3, a flexible hose 205c-5 communicating with the other end of the oil pipe 205c-2, and a supplementary pipe 205c-6 communicating with the lubricating oil box 205c-1.

[0065] The other end of the return spring 205c-4 is fixed to the inner wall of the housing 205a. The return spring 205c-4 is used to reset and close the valve handle on the valve 205c-3.

[0066] Furthermore, the first transmission assembly 205d includes a first rotating rod 205d-1 fixedly mounted on the inner wall of the driven gear roller 203f, a driving bevel gear 205d-2 fixedly connected to the end face of the first rotating rod 205d-1, a driven bevel gear 205d-3 meshing with the outer surface of the driving bevel gear 205d-2, a second rotating rod 205d-4 fixedly mounted on the inner wall of the driven bevel gear 205d-3, and a first cam disk fixedly connected to the end face of the second rotating rod 205d-4. 205d-5, a sleeve rod 205d-6 movably sleeved on the connecting post on the surface of the first cam disk 205d-5, a connecting rod 205d-7 hinged to the sleeve rod 205d-6, a reciprocating rod 205d-8 hinged to the other end of the connecting rod 205d-7, and a power rod 205d-9 fixedly connected to the end face of the reciprocating rod 205d-8. The other end of the power rod 205d-9 passes through the housing 205a and is fixed to the outer surface of the brush plate 205b-1.

[0067] The reciprocating rod 205d-8 is fitted with a limiting slide block, which is fixed to the inner wall of the housing 205a by a fixing rod. By setting the limiting slide block, the reciprocating rod 205d-8 can be limited to make it perform linear reciprocating motion.

[0068] It should be further noted that the second transmission assembly 205e includes a first gear disc 205e-1 fixedly sleeved on the middle section of the outer surface of the second rotating rod 205d-4, a second gear disc 205e-2 meshing with the first gear disc 205e-1, a third rotating rod 205e-3 fixedly installed on the inner wall of the second gear disc 205e-2, a second cam disc 205e-4 fixedly connected to the end face of the third rotating rod 205e-3, a suspension rod 205e-5 fixedly installed on the top of the inner cavity of the housing 205a, and a hinged to the suspension rod 205d-4. The bottom of the 05e-5 has a contact plate 205e-6, a limiting spring 205e-7 fixedly installed at the other end of the contact plate 205e-6, and a trigger head 205e-8 fixedly installed on one side of the outer surface of the contact plate 205e-6. The bottom of the contact plate 205e-6 is in contact with the surface of the second cam plate 205e-4, the top of the limiting spring 205e-7 is fixedly connected to the inner wall of the housing 205a, and the outer end of the trigger head 205e-8 is in contact with the valve handle of the valve 205c-3.

[0069] The outer diameter of the first toothed disc 205e-1 is half that of the second toothed disc 205e-2. Therefore, the brush plate 205b-1 reciprocates four times, and the second transmission component 205e can control the valve 205c-3 to open and close once, achieving the effect of intermittent oil supply, which is energy-saving and environmentally friendly. The contact plate 205e-6 slides in contact with the second cam disc 205e-4. The second cam disc 205e-4 can drive the contact plate 205e-6 to reciprocate and rotate, thereby enabling the trigger head 205e-8 to control the opening and closing of the valve handle of the valve 205c-3.

[0070] In use, the hydraulic motor reducer assembly 102b provides rotational power to the drive wheel 102a. The rotation of the drive wheel 102a drives the traveling mechanism 100 to move. Furthermore, the soft-bristle cleaning sleeve 203c contacts the track and rotates accordingly. The soft-bristle cleaning sleeve 203c drives the wheel body 203b, which in turn drives the transmission rod 203a. The transmission rod 203a drives the drive gear roller 203d to rotate, which in turn drives the rack and pinion belt 203e. The rack and pinion belt 203e drives the driven gear roller 203f, which in turn drives the first… Rotating rod 205d-1 drives the active bevel gear 205d-2, which in turn drives the driven bevel gear 205d-3 to rotate. The driven bevel gear 205d-3 then drives the second rotating rod 205d-4, which in turn drives the first cam disc 205d-5. The rotation of the first cam disc 205d-5 drives the connecting rod 205d-6 in a curved circular motion. The connecting rod 205d-6 then drives the connecting rod 205d-7, which in turn drives the reciprocating rod 205d-8 in a linear reciprocating motion. The drive rod 205d-9 drives the fluffing component 205b to perform a horizontal linear reciprocating motion, combing the surface of the soft-bristle cleaning sleeve 203c. Meanwhile, the second rotating rod 205d-4, during its rotation, also drives the first gear disc 205e-1 to rotate. The first gear disc 205e-1 drives the second gear disc 205e-2, which in turn drives the third rotating rod 205e-3. The third rotating rod 205e-3 then drives the second cam disc 205e-4. Under the elastic force of the limit spring 205e-7, the second cam disc 205e-4 rotates... The rotation can drive the contact plate 205e-6 to tilt back and forth. The contact plate 205e-6 drives the trigger head 205e-8, which in turn, with the cooperation of the return spring 205c-4, can intermittently switch the valve handle of the valve 205c-3. The lubricating oil in the lubricating oil box 205c-1 can enter the hose 205c-5 through the oil pipe 205c-2 by gravity, and then flow into the brush plate 205b-1 through the hose 205c-5. The lubricating oil then seeps into the brush needle 205b-2 from the brush plate 205b-1, and finally seeps out through the fine holes on the surface of the brush needle 205b-2.

[0071] In summary, during the rotation of the soft bristle cleaning sleeve 203c, the part cleaned by the mud and dirt collection component 204 will then rotate to the fluffing component 205b. The reciprocating fluffing component 205b can brush the fluffy ends of the soft bristle cleaning sleeve 203c, making it fluffier and more absorbent. It can also apply lubricant to the fluffy ends, which not only ensures the continuous absorption capacity of the soft bristle cleaning sleeve 203c for fine sand and dust on the track surface, but also applies oil to the track surface to improve lubrication, further enhancing the protection of the traveling mechanism 100.

[0072] Example 4

[0073] Reference Figure 14 This is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that the device is used in conjunction with the running scheme of the bearing steel plate and the driven wheel set on the track surface.

[0074] Furthermore, according to Figure 14 This invention is used to design a transport trolley with a total load capacity of 400t. The transport trolley has a total of 8 sets of wheels (4 sets of the device of this invention and 4 sets of driven wheels).

[0075] Furthermore, given that the mass of the load is 400t, the gravity N = 400 × 9.8 × 10 = 3920000N, and the coefficient of friction of the track is μ = 0.03 (refer to the mechanical handbook); calculate the friction force f. According to the formula f = μ·N = 0.03 × 3920000 = 117600N, the on-track friction force is 117600N.

[0076] The diameter of the drive wheel in the drive wheel assembly is selected as 387mm. According to the torque formula: t=M×F.

[0077] Where: t—torque N·m; M—lever arm m; F—force N.

[0078] The total driving torque required for the power trolley is: t=387 / 2*1000×117600=22755.6N·m2. Driving capacity calculation and correction design are also considered. Furthermore, considering the gaps at the track joints and the risk of the drive wheel set coming off course, the power trolley is driven in a four-wheel drive configuration with two sets of walking wheels at the front and two at the rear. Each walking wheel set is independently driven and does not interfere with each other, greatly improving the trolley's traveling ability. The four walking mechanisms are 100% independently controlled. By controlling the input flow, the trolley's walking wheels perform differential movements during travel to achieve vehicle correction, preventing deviation and rail wear. The control program includes both automatic and manual operation modes.

[0079] The technical parameters of the selected walking hydraulic motor reducer assembly 102b are as follows:

[0080] Maximum input flow rate: 80 L / min;

[0081] Motor displacement: 53 mL / r;

[0082] Maximum working pressure: 30MPa;

[0083] Gearbox reduction ratio: 45.569;

[0084] Theoretical output torque: 11500 N·m;

[0085] Rotation direction: bidirectional;

[0086] Braking method: hydraulic braking + brake pad braking.

[0087] When the driving pressure is 30MPa, the hydraulic motor output torque of a single drive wheel set is 11500N·m. The total output torque of the four drive wheel sets is 11500×4=46000N·m>22755.6N·m. The safety factor is 46000 / 22755=2.02, which meets the driving force design requirements.

[0088] The travel speed of the power trolley can be controlled by changing the speed of the hydraulic pump and thus the output flow. In this solution, the hydraulic pump drive motor is a variable frequency motor, and the maximum speed can be controlled to be 700-1450 r / min.

[0089] It should also be noted that both ends of the transmission rod 203a are mounted on the support frame 202 via one-way bearings. The one-way bearing design allows the soft-bristle cleaning sleeve 203c to rotate only in one direction with the trolley. The friction between the soft-bristle cleaning sleeve 203c and the track in the locked state is negligible. (Reference) Figure 14 The two sets of the present invention are arranged opposite each other to ensure that the track surface can be cleaned and maintained no matter which direction the power trolley moves, thus protecting the traveling mechanism 100 and extending its service life.

[0090] In summary, the hydraulic motor and reducer assembly 102b integrates the motor, reducer, and traveling wheels into one unit, significantly reducing the size of the device and enabling the mobile equipment to operate in extremely small spaces. The traveling wheel set adopts a front and rear dual-wheel structure with an eccentric load support design, offsetting the load support center axis towards the load-bearing driven wheel 103a without a hydraulic motor. Utilizing the lever principle of the spreader beam axle 104a, the load-bearing capacity of the two wheels in the traveling mechanism 100 is distributed differently, allowing more load to be distributed to the driven wheel 103a, exceeding the upper limit of the hydraulic motor's load-bearing capacity. This reduces the wheel set's size while increasing its upper limit of load-bearing capacity. The cleaning mechanism 200 is installed to pre-clean the track surface during travel, effectively removing mud and sand and applying lubricating oil to the track surface, improving the traveling mechanism 100's passability on the track surface and effectively extending the service life of the wheel set.
