Self-walking stair-climbing emergency UPS (Uninterrupted Power Supply)

Abstract

The utility model discloses a self-walking stair-climbing emergency UPS (Uninterrupted Power Supply) which comprises a power supply body, a power supply vehicle and a jacking mechanism, when the power van encounters steps of a building and needs to climb the building, the jacking supporting rods stretch out, the front end of the vehicle-mounted platform is jacked to fall off the ground, at the moment, the front wheels are suspended, and the rear wheels and the pulleys form driving wheels for driving the power van to move forwards; when the power van climbs to the steps, the jacking supporting rods are retracted, and stair climbing power is provided by the front wheels, the rear wheels and the crawler belts. Due to the fact that the jacking supporting rods are perpendicular to the vehicle-mounted platform, when the jacking supporting rods jack the vehicle-mounted platform and the power van moves forwards, the pulleys can jack the steps firstly, and therefore the climbing gradient is limited. Therefore, when a ladder with a large gradient is encountered, the jacking supporting rod moves in the direction away from the front wheel through the adjusting rod, namely, the jacking radius (the distance from the jacking supporting rod to the rear wheel) is reduced, the climbing gradient of the power van can be improved, and therefore the rapid arrangement capacity of the emergency UPS power supply in the complex environment with the ladder is improved.

It is a kind of power supply equipment containing an energy storage device. In order to make the emergency UPS power supply quickly deployable, safe, portable, self-propelled and other functions, the power body of the emergency UPS power supply is usually installed on a power supply vehicle, and the self-propelled function of the emergency UPS power supply is realized based on the self-propelled function of the power supply vehicle, so that the emergency UPS power supply has the advantage of being quickly deployed to the power outage point of the power grid. When the existing emergency UPS power supply needs to provide power in the face of sudden power outages in complex environments, especially when facing power supply in complex buildings, the existing emergency UPS power supply cannot realize the function of self-propelled climbing stairs, which results in the existing emergency UPS power supply being unable to be quickly deployed in the face of complex environments with stairs, and then losing its emergency properties. Therefore, a self-propelled climbing emergency UPS power supply is proposed. Utility Model Content

[0003] The utility model aims to provide a self-propelled stair climbing emergency UPS power supply to solve the above problems.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0016] Optionally, a track support plate is provided between the ground-contacting section and the suspended section of the track.

[0017] Compared with the prior art, the utility model has the following beneficial effects: by arranging the power supply body on the power supply vehicle, relying on the flexible maneuverability of the power supply vehicle, the self-propelled, fast-arranged and portable functions of the emergency UPS power supply are realized. When encountering the steps of the building and needing to climb the stairs, the lifting support rod is extended and the front end of the vehicle-mounted platform is lifted off the ground.

[0023] In order to make the purpose, features and advantages of the invention of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in combination with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments.

It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0025] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0026] Reference Figure 1 to Figure 2 The embodiment of the utility model provides a self-propelled stair climbing emergency UPS power supply, including a power supply body 10, a power supply vehicle 20 and a lifting mechanism 30. The power supply body 10 is arranged on the power supply vehicle 20, and the power supply body 10 is driven by the power supply vehicle 20, so as to realize the self-propelled, fast deployment and portable functions of the emergency UPS power supply. The power supply body 10 is provided with a battery pack, an inverter, etc., to provide AC power when the power grid is out of power.

[0027] The power supply vehicle 20 includes a vehicle-mounted platform 21, which is in a rectangular shape. A front wheel 22 is provided at one end of the vehicle-mounted platform 21, and a rear wheel 23 is provided at the other end. The front wheel 22 and the rear wheel 23 on the same side of the vehicle-mounted platform 21 are connected by a track 24. The design of the track 24 has the following advantages: ① The track 24 has a larger contact area on the ground than the solution of a simple front wheel 22 + rear wheel 23, and can distribute the weight of the power supply vehicle 20 more evenly; ② The track 24 can move on various complex terrains, such as uneven roads; ③ The track 24 has a larger contact area, and the unit pressure on the ground is smaller, reducing damage to the fragile ground. The power supply body 10 is arranged on the power supply vehicle 20, specifically, the power supply body 10 is arranged on the vehicle-mounted platform 21.

[0028] The lifting mechanism 30 is arranged on the lower end surface of the vehicle-mounted platform 21 and close to one end of the front wheel 22. Specifically, the lifting mechanism 30 is arranged on the side of the central axis of the vehicle-mounted platform 21 close to the front wheel 22, so that when climbing the stairs, the lifting mechanism 30 lifts the front end of the vehicle-mounted platform 21 and then climbs up the stairs. The lifting mechanism 30 includes a retractable lifting support rod 31, and when the front end of the vehicle-mounted platform 21 needs to be lifted, the lifting support rod 31 is extended. A pulley 32 is arranged at one end (i.e., the retractable end) of the lifting support rod 31 away from the vehicle-mounted platform 21. When the lifting support rod 31 is extended to lift the vehicle-mounted platform 21, the pulley 32 replaces the front wheel 22 and becomes the wheel of the new power supply vehicle 20, that is, the rear wheel 23 and the pulley 32 form a driving wheel that drives the power supply vehicle 20 forward. At this time, the power supply vehicle 20 is in a tilted state, and it can climb up the stairs by continuing to move forward, thereby realizing the stair climbing function of the self-propelled emergency UPS power supply.

[0029] In this embodiment, the lifting support rod 31 lifts the front and rear of the vehicle platform 21, and the lifting support rod 31 is in a vertical state with the vehicle platform 21. When the front end of the power supply vehicle 20 is lifted and in an inclined state, the lifting support rod 31 is perpendicular to the vehicle platform 21 and downward. At this time, the power supply vehicle 20 continues to move forward, and the pulley 32 will first collide with the stairs, thereby limiting the forward movement of the power supply vehicle 20. The closer the lifting support rod 31 is to the front wheel 22, the easier it is to occur. Therefore, the closer the lifting support rod 31 is to the front wheel 22, the smaller the slope of the stairs that can be climbed. If the lifting support rod 31 is always in a position away from the front wheel 22, the lifting force required to lift the vehicle platform 21 each time is at its maximum. For this reason, the lifting mechanism 30 of this embodiment also includes an adjusting rod 33, which is arranged at one end of the lifting support rod 31 close to the vehicle platform 21, and is used to adjust the position of the lifting support rod 31 in the forward direction.

[0030] Specifically, when encountering stairs of a building and needing to climb the stairs, the lifting support rod 31 is extended and the front end of the vehicle-mounted platform 21 is lifted off the ground. At this time, the front wheel 22 is suspended in the air, and the rear wheel 23 and the pulley 32 form a driving wheel for driving the power supply vehicle 20 forward; when the power supply vehicle 20 climbs onto the stairs, the lifting support rod 31 is retracted, and the front wheel 22, the rear wheel 23 and the crawler 24 provide the power for climbing the stairs. Since the lifting support rod 31 is perpendicular to the vehicle-mounted platform 21, when the lifting support rod 31 lifts the vehicle-mounted platform 21 and the power supply vehicle 20 moves forward, the pulley 32 will first hit the stairs, thereby limiting the climbing slope. To this end, when encountering a steep staircase, the lifting support rod 31 is moved away from the front wheel 22 by adjusting the rod 33, that is, the lifting radius (the distance from the lifting support rod 31 to the rear wheel 23) is reduced, which can increase the climbing slope of the power supply vehicle 20, thereby improving the ability of the emergency UPS power supply to be quickly deployed in a complex environment with stairs.

[0031] Furthermore, the lifting mechanism 30 also includes a bearing plate 34 fixed to the lower end surface of the vehicle-mounted platform 21 and a mounting seat 35 disposed on the bearing plate 34. The mounting seat 35 is slidably connected to the bearing plate 34, and the lifting support rod 31 is mounted on the mounting seat 35. By sliding the mounting seat 35, the lifting support rod 31 is moved in the forward direction.

[0032] The bearing plate 34 is provided with a guide groove 341, the cross section of which is in a "T" shape, and the mounting seat 35 is slidably connected in the guide groove 341. There are two lifting struts 31 and two bearing plates 34, which are symmetrically arranged on both sides of the vehicle platform 21, so as to improve the stability of the vehicle platform 21 after lifting. A through hole 342 is provided on the side walls of the two guide grooves 341 close to each other, and the thickness of the through hole 342 is less than the thickness of the mounting seat 35. The lifting mechanism 30 also includes a connecting rod 36, which passes through the through hole 342 and is fixedly connected to the two mounting seats 35, so as to realize the synchronous movement of the two mounting seats 35.

[0033] Furthermore, a slider 37 is provided on the connecting rod 36, and the center of the slider 37 coincides with the center of the connecting rod 36. The adjusting rod 33 is a threaded rod, and the slider 37 is provided with an internal threaded hole corresponding to the threaded rod, and the threaded rod passes through the slider 37. When the threaded rod rotates, the slider 37 slides on the threaded rod. Specifically, the slider 37 is threadedly connected to the threaded rod, and the slider 37 is restricted by the connecting rod 36 and cannot rotate. When the threaded rod rotates, the slider 37 slides on the threaded rod. In this embodiment, the driving motor 39 drives the threaded rod to rotate, the threaded rod drives the slider 37, and the slider 37 drives the connecting rod 36 and the mounting seat 35, thereby realizing the movement of the lifting support rod 31.

[0034] In the lifting mechanism 30 of the utility model, a double threaded rod solution can also be adopted, that is, an internal threaded hole corresponding to the threaded rod is set on the mounting seat 35, each mounting seat 35 is rotatably connected with a threaded rod, and one end of each threaded rod is connected to a driving motor 39. That is, two driving motors 39 drive a threaded rod to rotate respectively, and the threaded rod drives the mounting seat 35, thereby realizing the movement of the lifting support rod 31. The double threaded rod solution has stronger power when adjusting the position of the lifting support rod 31 in the forward direction, and can still provide driving force for adjusting the lifting support rod 31 after the lifting support rod 31 lifts the vehicle-mounted platform 21.

[0035] The two bearing plates 34 are connected by a fixing plate 38, and the fixing plate 38 is fixed to both ends of the bearing plates 34. A driving motor 39 is arranged on the fixing plate 38. The adjusting rod 33 is fixedly connected to the output shaft of the driving motor 39, and the axis of the adjusting rod 33 is in the same straight line as the axis of the output shaft of the driving motor 39. The adjusting rod 33 is rotatably connected to the fixing plate 38. When the driving motor 39 is working, the driving motor 39 drives the threaded rod to rotate, thereby adjusting the lifting support rod 31 to move in the forward direction of the power supply vehicle 20.

[0036] It should be noted that the two lifting struts 31 of this embodiment are synchronous lifting cylinders, that is, the two lifting cylinders can move simultaneously or synchronously.

[0037] Furthermore, a first sensor for sensing stairs is provided at the front end of the power supply body 10. When the power supply body 10 approaches the stairs and detects the stairs, the lifting support rod 31 extends and lifts the vehicle-mounted platform 21. A second sensor for sensing stairs is provided on the lower end surface of the vehicle-mounted platform 21. When the stairs are stepped down and the second sensor senses that the vehicle-mounted platform 21 is suspended in the air, the lifting support rod 31 extends and supports the vehicle-mounted platform 21 to prevent it from rolling due to unstable center of gravity.

[0038] Furthermore, a track support plate 25 is provided between the ground-connected section and the suspended section of the track 24. When the power supply vehicle 20 climbs stairs and the front wheels 22 or the rear wheels 23 are suspended in the air, the track support plate 25 provides support force.

[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
