Description

Technical Field

[0001] This invention relates to the field of diesel generator braking technology, specifically to a shock-absorbing braking system that can effectively ensure the stability of a diesel generator. Background Technology

[0002] Diesel generators are a type of power supply equipment with a wide range of applications. When assembled into mobile units, they are suitable for field operations in industrial and mining enterprises and construction machinery, as emergency backup power for telecommunications systems, and as emergency power sources for infrastructure projects. The advantages of this type of generator lie in its mobility and flexibility, providing stable power support in various environments and conditions.

[0003] However, the existing trailer-mounted generator sets are equipped with direct-push-the-ground brake levers, which do not have a shock absorption function. This causes the generator set to still generate a large amplitude when it is stopped, especially when it is parked on a soft surface. Its contact area with the ground is small, and it is easy to get stuck, which can lead to the failure of the braking function. Summary of the Invention

[0004] In order to overcome the deficiencies in the prior art, the present invention aims to provide a shock-absorbing braking system that can effectively ensure the stability of a diesel generator, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides a shock-absorbing braking system that can effectively ensure the stability of a diesel generator, comprising a generator housing and a diesel generator set installed inside it. A base is installed at the bottom of the generator housing, and shock-absorbing wheel sets are provided at both the front and rear of the bottom of the base. Each shock-absorbing wheel set includes a pair of coaxially connected wheels, a pair of spring-loaded plates sleeved with the central axle of the wheels, a shock absorber suspended above the spring-loaded plates, and a heat dissipation assembly located below the center of the shock absorber. The shock absorber includes a shock-absorbing tube filled with damping oil, a piston rod for transmitting the amplitude of the spring-loaded plates within the shock-absorbing tube, and a support frame for supporting the shock-absorbing tube on the center of the spring-loaded plates. The heat dissipation assembly includes a fan blade assembly, a transmission wheel coaxially connected to the fan blade assembly, and a cable for transmitting the amplitude of the spring-loaded plates to drive the transmission wheel to rotate.

[0006] The base has brake assemblies on both sides, front and back, for lifting the wheels and braking them when they touch the ground. The brake assembly includes a wheel cover fixedly connected to the bottom surface of the base, a pair of wheel brakes sealed to the wheel cover, and a servo electric cylinder for pumping out damping oil from the wheel cover. The bottom inner wall of the wheel brake is provided with several rollers, and the bottom outer wall of the wheel brake is provided with a support block along its tangential direction.

[0007] As a further improvement to this technical solution, a collar is welded to the center of the bottom surface of the pressure plate, and the collar is sleeved with the central shaft of the wheel and can slide. A pressure seat is provided directly above the pressure plate and is fixedly connected to the base. A pair of clamping blocks are provided at both ends of the pressure seat, and the pair of clamping blocks are hinged to one end of the pressure plate.

[0008] As a further improvement to this technical solution, the middle part of the shock absorber tube is a straight tube and its two ends are inclined downwards. The piston rod is inserted into the inclined section of the shock absorber tube. The upper end of the piston rod is tightly fitted with a round block and the end face of the round block is provided with several oil holes.

[0009] As a further improvement to this technical solution, the lower end of the piston rod is rotatably connected to a support by a pin. The support has a U-shaped structure and is engaged with and slidable with the pressure plate. The upper end of the support is fixedly connected to the shock absorber tube, and its lower end is fixedly connected to the middle of the pressure plate.

[0010] As a further improvement to this technical solution, a heat dissipation sleeve is snapped onto the bottom surface of the middle part of the shock-absorbing tube. The heat dissipation sleeve is made of thermally conductive metal with an open ring structure and several heat dissipation fins are provided at equal intervals on its outer side.

[0011] As a further improvement to this technical solution, the transmission wheel is wound with the pull wire, and the two ends of the pull wire are fixedly connected with sleeves. The sleeves are rotatably connected to the inner wall of the support by pins.

[0012] As a further improvement to this technical solution, the transmission wheel is tightly fitted with a transmission shaft in the center hole. The top outer side of the transmission shaft is provided with several vertically oriented slots. The fan blade assembly is composed of several fan blades and an integrally formed sleeve block at their inner ends. The inner wall of the sleeve block is provided with several vertically oriented storage slots. A lever is rotatably connected to the storage slot near its side. The outer end of the lever engages with the slot. A spring is provided between the outer end of the lever and the storage slot.

[0013] As a further improvement to this technical solution, a support rod is sleeved in the middle of the transmission shaft, and the two ends of the support rod are fixedly connected to the two ends of the shock absorber tube. A coil spring is provided on the transmission wheel, the inner end of the coil spring is bonded to the transmission shaft, and the outer end of the coil spring is bonded to the bottom surface of the support rod.

[0014] As a further improvement to this technical solution, the wheel cover has a hollow semi-circular ring structure with an opening at its bottom end. The top of the wheel cover is connected to an oil pipe. The output shaft of the servo electric cylinder is inserted into the opening of the oil pipe with a gap, and a circular block that slides and engages with the oil pipe is tightly sleeved on the outer end of the output shaft.

[0015] As a further improvement to this technical solution, the bottom end of the wheel cover is tightly fitted with a sleeve, the wheel brake has an arc structure and has locking blocks on both sides of its upper end, the wheel brake is fitted with the sleeve, and the locking blocks are slidably connected to the inner wall of the wheel cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. This shock-absorbing and braking system effectively ensures the stability of the diesel generator. Through the set shock-absorbing wheel set and brake set, a pair of wheel brakes surround the lower half of the wheel until the pair of wheel brakes converge and touch the ground, lifting the wheel and supporting it on the ground. Then, the support block forms a stable support by contacting the ground with a large area. The amplitude of the generator box is transmitted to the pressure plate through the pressure seat, which then drives the piston rod to move in and out of the shock-absorbing tube. At the same time, heat is generated by the compression of the oil hole, thereby converting the vibration amplitude of the pressure plate. The heat is then quickly dissipated through the heat dissipation jacket, which accelerates the energy conversion and plays a role in shock absorption.

[0018] 2. This shock-absorbing and braking system, which can effectively ensure the stability of the diesel generator, uses a heat dissipation group. When the pressure plate vibrates, the support seat pulls the cable, which in turn drives the transmission wheel to rotate. Under the elastic force of the spring plate, the lever pops out of the storage slot and locks into the slot. That is, the rotation of the transmission shaft drives the fan blade group to rotate, increasing the airflow speed and accelerating heat dissipation and energy dissipation.

However, the specific embodiments of the present invention described herein are for illustrative purposes only and should not be construed as limiting the invention in any way. Under the teachings of this invention, those skilled in the art can conceive of any possible modifications based on the invention, and these should all be considered to fall within the scope of the invention.

Furthermore, in the description of the invention, "a number" means two or more, unless otherwise explicitly specified.

[0038] Please see Figures 1-12 As shown, the present invention provides a shock-absorbing braking system that can effectively ensure the stability of a diesel generator, including a generator housing 100 and a diesel generator set installed inside it. A base 110 is installed at the bottom of the generator housing 100, and shock-absorbing wheel sets 200 are provided at the front and rear of the bottom of the base 110 for supporting the movement and stopping of the generator housing 100 and for shock absorption. The shock-absorbing wheel set 200 includes a pair of coaxially connected wheels 210, a pair of spring pressure plates 220 sleeved with the central axle of the wheels 210, a shock absorber 230 suspended above the spring pressure plates 220, and a heat dissipation group 240 located below the middle of the shock absorber 230. The spring pressure plates 220 are made of spring steel and are rod-shaped with both ends raised, using their elasticity to buffer the vibration amplitude of the generator housing 100 during operation.

[0039] The shock absorber 230 includes a shock-absorbing tube 231 filled with damping oil, a piston rod 232 for transmitting the amplitude of the spring pressure plate 220 into the shock-absorbing tube 231, and a support frame 235 for supporting the shock-absorbing tube 231 on the middle of the spring pressure plate 220. This allows the shock-absorbing tube 231 to be stably suspended. When the generator box 100 vibrates due to the operation of the diesel generator, the spring pressure plate 220 bounces up and down at both ends by buffering the amplitude, which in turn drives the piston rod 232 to reciprocate within the shock-absorbing tube 231. This causes the friction damping oil to heat up, and the heat is dissipated from the shock-absorbing tube 231, thus converting the amplitude and achieving the effect of damping the generator box 100.

[0040] Furthermore, the heat dissipation assembly 240 includes a fan blade assembly 241, a transmission wheel 242 coaxially connected to the fan blade assembly 241, and a pull wire 243 for transmitting the amplitude of the spring pressure plate 220 to drive the transmission wheel 242 to rotate. By the spring pressure plate 220 bouncing up and down at both ends, the pull wire 243 is pulled, thereby driving the transmission wheel 242 to rotate, which in turn drives the fan blade assembly 241 to rotate, thereby accelerating the heat dissipation process of the damping tube 231 and achieving a further effect of damping the generator box 100.

[0041] In addition, brake assemblies 300 are provided on both sides and front and rear of the base 110 to lift the wheel 210 and brake it when it touches the ground; this allows the generator box 100 to be parked stably on the ground, facilitating the transfer of the generator box 100; the brake assembly 300 includes a wheel cover 310 fixedly connected to the bottom surface of the base 110, a pair of wheel brakes 320 sealed to the wheel cover 310, and a servo cylinder 330 for pumping out the damping oil inside the wheel cover 310; the wheel cover 310 is located outside the upper half of the wheel 210 and is coaxially arranged; when the servo cylinder 330 is activated, its output shaft is driven to squeeze out the damping oil on the top of the wheel cover 310, thereby pushing out the pair of wheel brakes 320 around the center axis of the wheel 210. The wheels deflect around the central axis and converge at the bottom of the wheel 210, supporting the wheel 210 on the ground to form a braking state. The inner wall of the bottom end of the wheel brake 320 is provided with several rollers 321, and the side of the bottom end of the wheel brake 320 is provided with a protrusion 324. The two ends of the rollers 321 are embedded in the side wall of the protrusion 324 and rotate. The rollers 321 are in rolling contact with the outer surface of the wheel 210 to reduce friction. When a pair of wheel brakes 320 touch the ground and converge, they can smoothly support the wheel 210. The outer wall of the bottom end of the wheel brake 320 is provided with a support block 322 along its tangential direction. The contact plane formed by the support block 322 ensures that the friction force at the ground is sufficient for braking.

[0042] Furthermore, a collar is welded to the center of the bottom surface of the pressure plate 220, and the collar is sleeved with the central shaft of the wheel 210 and can slide, so that the wheel 210 can roll smoothly and can be supported by the pressure plate 220 to back the generator box 100; a pressure seat 221 fixedly connected to the base 110 is provided directly above the pressure plate 220, and a pair of clamping blocks are provided at both ends of the pressure seat 221. The pair of clamping blocks are hinged to one end of the pressure plate 220, that is, the amplitude of the generator box 100 is transmitted to the pressure plate 220 through the pressure seat 221, and then the pressure plate 220 is used for buffering.

[0043] Furthermore, the middle part of the shock absorber tube 231 is a straight tube with both ends inclined downwards. The piston rod 232 is inserted into the inclined section of the shock absorber tube 231. A round block is tightly fitted at the upper end of the piston rod 232, and several oil holes 2321 are opened through the end face of the round block. A sealing ring is fitted at the end of the inclined section of the shock absorber tube 231 to seal the piston rod 232. The oil holes 2321 are used to circulate the damping oil separated by the round block inside the shock absorber tube 231. Heat is generated by the compression of the oil holes 2321, thereby converting the vibration amplitude of the pressure plate 220.

[0044] Furthermore, the lower end of the piston rod 232 is rotatably connected to a support 233 via a pin. The support 233 has a U-shaped structure and is engaged with the pressure plate 220 and can slide. The upper end of the support 235 is fixedly connected to the shock absorber tube 231, and its lower end is fixedly connected to the middle of the pressure plate 220, so that the shock absorber tube 231 is stably suspended, and then the piston rod 232 is driven to reciprocate and extend through the vibration of both ends of the pressure plate 220.

[0045] A heat dissipation sleeve 234 is snapped onto the bottom of the middle part of the shock-absorbing tube 231. The heat dissipation sleeve 234 is made of thermally conductive metal with an open ring structure and several heat dissipation fins are provided at equal intervals on its outer side. It is preferably made of aluminum alloy.

[0046] Specifically, the transmission wheel 242 is wound with the pull wire 243, and the two ends of the pull wire 243 are fixedly connected with sleeves 2431. The pull wire 243 is made of steel strand, making it tensile and durable. The sleeves 2431 are rotatably connected to the inner wall of the support 233 by pins, so that when the pressure plate 220 vibrates, the support 233 drives the pull wire 243 to be pulled, which in turn drives the transmission wheel 242 to rotate.

[0047] The transmission shaft 2421 is tightly fitted into the center hole of the transmission wheel 242. The top outer side of the transmission shaft 2421 has several vertically oriented slots 2422. The fan blade assembly 241 is composed of several fan blades and an integrally formed sleeve block at its inner end. The inner wall of the sleeve block has several vertically oriented storage slots 2413. A lever 2411 is rotatably connected to the storage slot 2413 near its side. The outer end of the lever 2411 engages with the slot 2422. A spring piece 2412 is provided between the outer end of the lever 2411 and the storage slot 2413. Under the elastic force of the spring piece 2412, the lever 2411 pops out of the storage slot 2413 and engages with the slot 2422. That is, the rotation of the transmission shaft 2421 drives the fan blade assembly 241 to rotate, increasing the airflow speed and accelerating heat dissipation and energy dissipation.

[0048] A support rod 245 is sleeved in the middle of the drive shaft 2421. The two ends of the support rod 245 are fixedly connected to the two ends of the shock absorber tube 231 to support the drive shaft 2421 for stable rotation. A coil spring 244 is provided on the drive wheel 242. The inner end of the coil spring 244 is bonded to the drive shaft 2421, and the outer end of the coil spring 244 is bonded to the bottom surface of the support rod 245. This allows the stretched pull wire 243 to wind back onto the drive wheel 242 under the action of the coiling force of the coil spring 244. At this time, the drive shaft 2421 rotates, and the slot 2422 switches to sliding contact with the lever 2411 to avoid stopping the fan blade assembly 241 from rotating. After the pull wire 243 is stretched again, the drive shaft 2421 rotates forward and uses the slot 2422 to lock the lever 2411, thereby driving the fan blade assembly 241 to continue rotating with increased force.

[0049] It is worth noting that the wheel cover 310 has a hollow semi-circular ring structure with an opening at the bottom. The top of the wheel cover 310 is connected to an oil pipe 311. The output shaft of the servo electric cylinder 330 is inserted into the opening of the oil pipe 311 with a gap, and a round block that slides and fits tightly on the outer end of the output shaft is connected to the oil pipe 311. This allows the opening of the oil pipe 311 to communicate with the outside when the round block extends or retracts, avoiding obstruction. The outer side of the round block is wrapped with a sealing ring to prevent the damping oil in the oil pipe 311 from leaking.

[0050] The bottom end of the wheel cover 310 is tightly fitted with a sealing sleeve 312 to seal the damping oil; the wheel brake 320 has an arc structure and has a locking block 323 on both sides of its upper end. The wheel brake 320 is fitted with the sealing sleeve 312. The bottom surface of the sealing sleeve 312 is open and has a sealing sleeve attached. The locking block 323 is slidably connected to the inner wall of the wheel cover 310. The top of the wheel brake 320 and the outer side of the locking block 323 are completely covered with a sealing sleeve to seal the inner wall of the wheel cover 310 and ensure that the damping oil does not leak. When the servo electric cylinder 330 drives its output shaft to retract, a vacuum negative pressure state is formed in the oil pipe 311. Under the action of atmospheric pressure, the wheel brake 320 is attracted and retracted into the wheel cover 310, that is, the wheel 210 touches the ground and rolls, thereby driving the generator box 100 to move.

[0051] Before operation, the shock-absorbing braking system of the present invention, which can effectively ensure the stability of the diesel generator, first transports the generator box 100 to the place where power generation is needed and stops it. Then, it drives several servo cylinders 330 to drive the output shaft to squeeze the damping oil in the oil pipe 311 into the wheel cover 310, and squeezes out a pair of wheel brakes 320 to surround the lower half of the wheel 210 until the pair of wheel brakes 320 converge and touch the ground, lifting the wheel 210 and supporting it on the ground.

[0052] At this point, the generator set can be started and operated. The vibration generated during its operation is transmitted to the damping wheel assembly 200 through the base 110, and then transmitted to the pressure plate 220 through the pressure seat 221. The pressure plate 220 then buffers the vibration. The piston rod 232 then moves in and out of the damping tube 231. At the same time, the piston rod generates heat through the compression of the oil hole 2321, thereby converting the vibration amplitude of the pressure plate 220. The heat is then quickly dissipated through the heat dissipation sleeve 234, which accelerates the energy conversion and plays a role in shock absorption.

[0053] In addition, when the pressure plate 220 vibrates, the support 233 drives the pull wire 243 to be pulled, which in turn drives the transmission wheel 242 to rotate. Under the elastic force of the spring piece 2412, the lever 2411 pops out of the storage groove 2413 and gets into the slot 2422. That is, the rotation of the transmission shaft 2421 drives the fan blade assembly 241 to rotate, increasing the airflow speed and accelerating heat dissipation and energy dissipation.

[0054] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
