[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-3 As shown, this embodiment provides an emergency device for refueling equipment, including: a base 10, an oil delivery assembly 20, a handrail 31, a fixing member 32, and a connecting member 33. The bottom of the base 10 is provided with casters. The oil delivery assembly 20 is supported on the top of the base 10 by a base plate 21. The oil delivery assembly 20 is adapted to be connected to the refueling pipeline 1. The handrail 31 is rotatably connected to the base 10. The fixing member 32 is movably connected to the base 10. One end of the connecting member 33 is rotatably connected to the handrail 31, and the other end of the connecting member 33 is rotatably connected to the fixing member 32. The handrail 31 rotates to drive the fixing member 32 to move, so that the fixing member 32 can selectively cooperate with the base 10 and clamp the base plate 21.

[0026] In some embodiments, the base 10 is equipped with casters to enable the emergency device to move flexibly and quickly adjust its position according to actual needs, adapting to refueling emergency requirements in different scenarios. The fuel delivery assembly 20 is stably supported on top of the base 10 by the base plate 21. The fuel delivery assembly 20 can be connected to the existing refueling pipeline 1, thereby ensuring the normal delivery of fuel in emergency situations. The handrail 31 is rotatably connected to the base 10, allowing the handrail 31 to rotate within a certain range, providing a means for moving the drive fixing member 32. As a fulcrum, the fixing member 32 is movably connected to the base 10. The fixing member 32 can move on the base 10 to fit with the base 10, thereby clamping and fixing the bottom plate 21 of the oil delivery assembly 20 and ensuring the stability of the oil delivery assembly 20 during operation. One end of the connecting member 33 is rotatably connected to the handrail 31, and the other end of the connecting member 33 is rotatably connected to the fixing member 32. When the handrail 31 rotates, the rotational motion is converted into the movement of the fixing member 32 through the connecting member 33, thereby realizing the clamping or loosening operation of the fixing member 32 on the bottom plate 21.

[0027] It is understandable that the handrail 31 has a first state and a second state. In the first state, the handrail 31 is in contact with the base 10 to reduce the space occupied by the emergency device in the height direction, so as to facilitate the storage and transportation of the emergency device. In the second state, the handrail 31 intersects with the base 10. At this time, the staff can push or pull the handrail 31 to drive the emergency device to move, thereby facilitating the movement of the emergency device.

[0028] When the handrail 31 is in the first state, the projection of the fixing member 32 in the height direction of the base 10 is spaced apart from the base plate 21. When the handrail 31 is in the second state, the projection of the fixing member 32 in the height direction of the base 10 at least partially overlaps with the base plate 21.

[0029] When the handrail 31 switches from the first state to the second state, the handrail 31 drives the fixing member 32 to move towards the base plate 21 through the connector 33. When the fixing member 32 moves to the side of the base plate 21 away from the base 10, the fixing member 32 cooperates with the base 10 to clamp and fix the base plate 21. When the handrail 31 switches from the second state to the first state, the handrail 31 drives the fixing member 32 away from the base plate 21 through the connector 33. When the fixing member 32 moves to the point of disengaging from the base plate 21, the fixing of the base plate 21 is released. At this time, the staff can easily remove the oil delivery assembly 20.

[0030] Understandably, when an emergency device is needed, staff can first place the oil delivery assembly 20 on the base 10, and then rotate the handrail 31 to switch the handrail 31 to the second state, which will fix the oil delivery assembly 20 to the base 10, preventing the oil delivery assembly 20 from shifting when the moving trolley vibrates or bumps, making the transportation of the oil delivery assembly 20 more convenient.

[0031] Furthermore, after the oil delivery component 20 is used, it needs to be disassembled from the base 10 and cleaned. With the above-mentioned arrangement, after the oil delivery component 20 is used, the staff only needs to rotate the handrail 31 to switch the handrail 31 to the first state to release the oil delivery component 20 from the base 10. At this time, the staff can easily remove the oil delivery component 20 and clean it.

[0032] According to the present invention, the emergency device for refueling equipment can fix the oil delivery component 20 to the base 10 or release the fixation between the oil delivery component 20 and the base 10 by rotating the handle 31. The connection between the oil delivery component 20 and the base 10 is more convenient, which not only avoids displacement of the oil delivery component 20 during transportation, but also makes it easy to disassemble the oil delivery component 20 from the base 10, thus improving the ease of use of the emergency device.

[0033] It is worth mentioning that the handrail 31 includes an upper rod 311 and a lower rod 312. The bottom of the lower rod 312 is rotatably connected to the base 10, and one end of the lower rod 312 is rotatably connected to the connector 33. The upper rod 311 and the lower rod 312 are movably connected. Thus, the height of the handrail 31 can be adjusted through the above settings, making it convenient for workers of different heights to use the handrail 31 and improving the applicability of the emergency device.

[0034] Furthermore, an adjustment space is formed between the upper rod 311 and the lower rod 312. When the upper rod 311 moves relative to the lower rod 312, the size of the adjustment space will also change. When the handrail 31 is rotated to the first state, the positional relationship between the upper rod 311 and the lower rod 312 can be adjusted so that the oil delivery assembly 20 is located within the adjustment space, thus avoiding interference from the handrail 31 to the disassembly and assembly of the oil delivery assembly 20.

[0035] According to some embodiments of the present invention, the emergency device further includes an elastic support base, which is connected to the base 10. The elastic support base is provided with a support part that is suitable for moving along the height direction of the base 10, and the support part is suitable for cooperating with the base plate 21.

[0036] In some embodiments, when the oil delivery assembly 20 is placed on the base 10, the base plate 21 contacts the support portion of the elastic support seat. Since the support portion can move along the height direction of the base 10, the elastic support seat will undergo elastic deformation when the oil delivery assembly 20 is subjected to its own weight or external vibration, impact, etc., thereby offsetting part of the pressure and playing a buffering and shock absorption effect.

[0037] Furthermore, when the fastener 32 is located on the side of the base plate 21 away from the base 10, the fastener 32 can apply a downward pressure to the base plate 21 to compress the elastic support seat, so that the elastic support seat is in a pre-tightened state. Thus, the above-mentioned arrangement can improve the fixing effect of the base plate 21 and also improve the buffering and vibration reduction effect of the elastic support seat.

[0038] According to some embodiments of the present invention, the elastic support base includes a fixing plate 41, which is connected to the base 10. A buffer member 42 is provided on the top of the fixing plate 41, and a support plate 43, which is configured as a support part, is provided on the top of the buffer member 42.

[0039] In some embodiments, when the oil delivery assembly 20 is placed on the support plate 43, the weight of the base plate 21 and the external forces that may be subjected to it (such as vibration, impact, etc.) will be transmitted to the buffer 42 through the support plate 43. After being subjected to force, the buffer 42 will undergo elastic deformation, such as compression or stretching (depending on the material of the buffer 42 and the direction of the force). This elastic deformation can consume and disperse the external force, converting some of the energy into the elastic potential energy of the buffer 42 itself. When the external force disappears, the buffer 42 will return to its initial state by relying on its own elastic restoring force, and at the same time drive the support plate 43 to reset, thereby achieving buffering and stable support for the oil delivery assembly 20.

[0040] According to some embodiments of the present invention, the buffer 42 includes a sleeve 421, which is connected to the fixing plate 41. A return spring 422 is provided inside the sleeve 421. The free end of the return spring 422 is connected to a support rod 423. A portion of the support rod 423 is located outside the sleeve 421 and is connected to the support plate 43.

[0041] In some embodiments, when the oil delivery assembly 20 is placed on the support plate 43, the weight of the base plate 21 and any external forces (such as vibration, impact, etc.) that may be applied are transmitted to the support rod 423 through the support plate 43. After the support rod 423 is subjected to downward pressure, it will move downward within the sleeve 421 and compress the return spring 422. After being compressed, the return spring 422 will generate an elastic force opposite to the direction of the pressure. This elastic force will act upward on the support rod 423, thereby generating an upward supporting force on the base plate 21 through the support plate 43, which plays a role in buffering and balancing external forces. When the external force disappears, the return spring 422 will return to its original state under the action of its own elastic force, pushing the support rod 423 upward and causing the support plate 43 to return to its initial position, preparing for the next force application.

[0042] It is worth mentioning that the sleeve 421 provides a stable installation environment for the return spring 422 and the support rod 423, which can prevent the return spring 422 from bending or shifting when under force, and ensure that the support rod 423 can only move along the axial direction of the sleeve 421, thereby improving the structural stability and reliability of the buffer 42.

[0043] According to some embodiments of the present invention, a positioning block 431 is provided on the top of the support plate 43, and a positioning groove suitable for receiving the positioning block 431 is provided on the bottom of the base plate 21.

[0044] Understandably, the cooperation between the positioning block 431 and the positioning groove can ensure that the oil delivery assembly 20 is quickly and accurately positioned on the base 10 during installation, thereby improving the assembly efficiency of the oil delivery assembly 20 and the base 10 and reducing the adjustment time caused by inaccurate installation position.

[0045] According to some embodiments of the present invention, a first guide surface 321 is provided on the side of the fixing member 32 facing the base plate 21, and a second guide surface 211 is provided on the side of the base plate 21 facing the fixing member 32. The first guide surface 321 is adapted to cooperate with the second guide surface 211.

[0046] In some embodiments, the first guide surface 321 and the second guide surface 211 are inclined surfaces or curved surfaces with a certain inclination angle or a specific curvature. When the base plate 21 approaches the fixing member 32 during installation or movement, the first guide surface 321 and the second guide surface 211 will come into contact with each other, and a component force along the direction of the guide surface will be generated during the contact process. This component force will guide the base plate 21 to move in the direction toward the base 10, so that the top surface of the base plate 21 can abut against the bottom surface of the fixing member 32. When the base plate 21 moves toward the base 10, it will compress the return spring 422, so that the return spring 422 is in a pre-tightened state to improve the cushioning effect of the base plate 21.

[0047] According to some embodiments of the present invention, the handrail 31 is rotatably disposed at one end of the base 10 in the length direction. The emergency device also includes a first fence 51. The base 10 is provided with a first fence 51 on both sides in the width direction. The first fence 51 is adapted to move along the length direction of the base 10. At least one first fence 51 is connected to the fixing member 32. The other end of the connecting member 33 is rotatably connected to the first fence 51.

[0048] In some embodiments, one first fence 51 may be connected to the fixing member 32, or both first fences 51 may be connected to the fixing member 32; there is no limitation here. When both first fences 51 are connected to the fixing member 32, both ends of the handrail 31 are connected to the first fence 51 through a connector 33, which can increase the driving force on the fixing member 32, thereby allowing the fixing member 32 to move more stably.

[0049] It is worth mentioning that the oil delivery assembly 20 is positioned between two first fences 51, and the two first fences 51 can provide protection for the oil delivery assembly 20.

[0050] According to some embodiments of the present invention, the base 10 is provided with a receiving cavity, and the elastic support seat and the fixing member 32 are both provided in the receiving cavity. The top of the base 10 is provided with a placement opening that is directly opposite to and through the support part. The top of the base 10 is also provided with a sliding groove 11 that is directly opposite to and through the first fence 51. The bottom of the first fence 51 extends into the receiving cavity through the sliding groove 11 and is connected to the fixing member 32.

[0051] In some embodiments, when it is necessary to assemble the oil delivery assembly 20 with the base 10, the operator only needs to place the base plate 21 of the oil delivery assembly 20 into the mounting opening to achieve stable engagement between the base plate 21 and the support plate 43 and to place the base plate 21 in a preset position. At this time, the operator can rotate the handle bar 31 to control the movement of the fixing member 32, thereby fixing or releasing the fixing of the base plate 21, which further facilitates the assembly efficiency of the oil delivery assembly 20 and the base 10.

[0052] It is understood that the extension direction of the slide groove 11 is parallel to the length direction of the base 10. The inner peripheral wall of the slide groove 11 can restrict the outer peripheral wall of the first guardrail 51, allowing the first guardrail 51 to move stably along the extension direction of the slide groove 11, thereby allowing the first guardrail 51 to move stably along the length direction of the base 10, and consequently allowing the fixing member 32 to move stably along the length direction of the base 10. Thus, the above arrangement makes the movement of the fixing member 32 more stable, thereby ensuring the assembly effect between the oil delivery assembly 20 and the base 10.

[0053] It is worth mentioning that, through the above-mentioned arrangement, the first fence 51 can not only protect the oil delivery component 20, but also serve as an intermediate linkage for driving the movement of the fixing component 32, thereby reducing the number of parts in the emergency device of this application and simplifying the structure of the emergency device of this application.

[0054] According to some embodiments of the present invention, the oil delivery assembly 20 includes an oil pump 22, the oil inlet of the oil pump 22 is connected to a first oil delivery pipe mechanism 23, the oil outlet of the oil pump 22 is connected to a second oil delivery pipe mechanism 24, the bottom of the oil pump 22, the first oil delivery pipe mechanism 23 and the second oil delivery pipe mechanism 24 are all provided with a base plate 21, and the fixing members 32 are constructed in multiple ways corresponding to the base plate 21, and the multiple fixing members 32 are all connected to the first fence 51.

[0055] In some embodiments, one end of the first oil pipeline mechanism 23 is connected to the oil tank, the other end of the first oil pipeline mechanism 23 is connected to the oil inlet of the oil pump 22, one end of the second oil pipeline mechanism 24 is connected to the oil outlet of the oil pump 22, and the other end of the second oil pipeline mechanism 24 is connected to the refueling pipeline 1. The oil pump 22 serves as the core power source for oil transportation, and the oil can be transported through the action of the oil pump 22.

[0056] In other embodiments, the first oil delivery pipe mechanism 23 includes a first oil delivery pipe and a first winding device for winding the first oil delivery pipe, and the second oil delivery pipe mechanism 24 includes a second oil delivery pipe and a second winding device for winding the second oil delivery pipe. The bottom of the first winding device, the bottom of the second winding device, and the bottom of the oil pump 22 are all provided with a base plate 21. Three fixing members 32 are provided, and all three fixing members 32 are connected to the first fence 51. Thus, by rotating the handrail 31, the three fixing members 32 can be driven to move. The movement of the three fixing members 32 can fix or release the first winding device, the second winding device, and the oil pump 22 respectively.

[0057] According to some embodiments of the present invention, the emergency device further includes a second fence 52, which is disposed at the other end of the base 10 along its length.

[0058] It is understandable that the oil delivery component 20 is positioned between the handrail 31, the second fence 52, and the two first fences 51. Thus, the handrail 31, the second fence 52, and the two first fences 51 can together form a protective fence for the oil delivery component 20, preventing the oil delivery component 20 from accidentally colliding with external objects and improving the protection effect of the oil delivery component 20.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
