Description

Technical Field

[0001] This utility model relates to the field of drainage pump truck technology, specifically to an emergency mobile drainage pump truck. Background Technology

[0002] Emergency mobile drainage pumping vehicles are crucial rescue equipment for responding to emergencies such as urban flooding and flood disasters. Traditional emergency mobile drainage pumping vehicles often employ a design where the diesel tank is suspended and mounted under the frame or chassis. However, this suspended fuel tank design has significant safety and stability defects in practical applications. Because emergency drainage operations typically involve complex and harsh road conditions, the pumping vehicle inevitably experiences severe road bumps during relocation. Over time, this can easily lead to cracking of welds, seal failure, or even structural breakage in the fuel tank body or connecting parts, resulting in fuel leaks. Utility Model Content

[0003] The main purpose of this utility model is to provide an emergency mobile drainage pump truck to solve the problem that, due to the complex and harsh road conditions in the emergency drainage operation environment, the pump truck will inevitably experience severe road bumps during the relocation process. Over time, this can easily cause cracks in the welds of the fuel tank body or connecting parts, seal failure, or even structural breakage, which in turn leads to fuel leakage.

[0004] To achieve the above objectives, this utility model provides an emergency mobile drainage pump truck, comprising two strip-shaped oil tanks and a traction beam;

[0005] Two strip-shaped oil tanks are arranged side by side and fixedly connected by multiple support plates, forming a rectangular chassis with the multiple support plates;

[0006] A diesel engine and a water pump are fixed at the top of a rectangular chassis. The diesel engine is connected to the water pump via a coupling and is also connected to two strip-shaped fuel tanks.

[0007] A traction beam is fixed at the bottom of a rectangular chassis. The traction beam is arranged along the length of the rectangular chassis and has a detachable traction component at its front end for use with a mobile vehicle. A drive shaft is rotatably threaded through the rear end of the traction beam. The drive shaft is arranged along the width of the rectangular chassis and has wheels fixed at both ends.

[0008] A preferred solution is to arrange two strip-shaped oil tanks side by side and integrate them with multiple receiving plates into a single structure.

[0009] A preferred option is to use a flexible coupling.

[0010] A preferred embodiment is that the water pump has an inlet pipe and an outlet pipe, and both the inlet end of the inlet pipe and the outlet end of the outlet pipe are welded with fixed flanges.

[0011] A preferred embodiment is that the traction component includes a triangular shell, a bracket, a first arc-shaped plate, a connecting plate, and a positioning pin;

[0012] The bottom end of the bracket is fixedly connected to the traction beam, and the top end is fitted with a pivot rod;

[0013] One end of each of the two first arc-shaped plates is fixedly connected to both ends of the shaft, and the other end is hinged to the two side walls of the triangular shell.

[0014] One end of each of the two connecting plates is hinged to the two side walls of the traction beam, and the other end is hinged to the two side walls of the triangular shell.

[0015] A second arc plate is fixed at one end of each connecting plate near the traction beam, and multiple positioning holes are opened along the outer arc edge of the second arc plate.

[0016] The traction beam has perforations along its width.

[0017] The locating pin passes through one locating hole, a through hole, and another locating hole in sequence;

[0018] A traction ring is fixed to the side wall of the triangular shell away from the traction beam.

[0019] A preferred embodiment is that lifting frames are fixed at all four corners of the rectangular chassis, and a base plate is fixed at the bottom of the lifting frames.

[0020] A preferred embodiment is that the emergency mobile drainage pump truck also includes a rectangular shell, with the diesel engine housed inside the rectangular shell. The rectangular shell is fixed to the top of the rectangular chassis, and four lifting rings are arranged in a matrix on the top wall.

[0021] The beneficial effects of the above scheme are:

[0022] The design employs two parallel, strip-shaped fuel tanks, fixedly connected by multiple support plates to form a rectangular chassis. A diesel engine and water pump are mounted at the top of the rectangular chassis, with the diesel engine connected to the fuel tanks. A traction beam is located at the bottom of the rectangular chassis, with a detachable connection to a mobile vehicle at the front and wide-base wheels driven by a driveshaft at the rear. This design disperses vibration loads through the overall frame, reducing localized stress in the fuel tanks and preventing weld cracking and seal failure. The low center of gravity of the strip-shaped fuel tanks and rectangular chassis enhances stability, while the wide-base wheels reduce the impact of lateral vibrations. Compared to traditional suspended fuel tanks, this invention fundamentally solves the safety hazards of fuel tanks under complex operating conditions, improving equipment reliability and emergency response efficiency.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Example:

[0030] like Figure 1 , Figure 2As shown, this embodiment provides an emergency mobile drainage pumping vehicle, including two strip-shaped fuel tanks 10 and a traction beam 30. The two strip-shaped fuel tanks 10 are arranged side-by-side and fixedly connected by multiple support plates 11, forming a rectangular chassis 12. The two strip-shaped fuel tanks 10 and the multiple support plates 11 are an integral structure. A diesel engine (not shown) and a water pump 20 are fixed to the top of the rectangular chassis 12. Both the diesel engine and the water pump 20 utilize existing technology and will not be described in detail. The diesel engine is connected to the water pump 20 via a coupling 21, and the diesel engine is also connected to the two strip-shaped fuel tanks 10. The coupling 21 is a flexible coupling 21. The flexible coupling 21 significantly improves the reliability and operational efficiency of the emergency mobile drainage pumping vehicle under complex working conditions by compensating for shaft misalignment, absorbing vibration and shock, reducing noise, and lowering maintenance costs. A lifting frame 50 is fixed to each of the four corners of the rectangular chassis 12, and a base plate 51 is fixed to the bottom of the lifting frame 50. The lifting frame 50 is based on existing technology and will not be described in detail here; please refer to patent publication number: CN207261394U - A Manual Lifting Frame. A traction beam 30 is fixed to the bottom of the rectangular chassis 12. The traction beam 30 is arranged along the length of the rectangular chassis 12, and its front end is provided with a detachable traction component 40 for use with a mobile vehicle. A drive shaft 31 is rotatably threaded through the rear end of the traction beam 30. The drive shaft 31 is arranged along the width of the rectangular chassis 12, and wheels 32 are fixedly mounted at both ends of the drive shaft 31. Figure 2 As shown, the traction component 40 includes a triangular shell 41, a bracket 42, a first arc-shaped plate 43, a connecting plate 44, and a positioning pin 45. The bottom end of the bracket 42 is fixedly connected to the traction beam 30, and a shaft 46 is rotatably mounted on the top end of the bracket 42. One end of each of the two first arc-shaped plates 43 is fixedly connected to both ends of the shaft 46, and the other end of each of the two first arc-shaped plates 43 is hinged to the two side walls of the triangular shell 41. One end of each of the two connecting plates 44 is hinged to the two side walls of the traction beam 30, and the other end of each of the two connecting plates 44 is hinged to the two side walls of the triangular shell 41. A second arc-shaped plate 47 is fixedly mounted on the end of each connecting plate 44 near the traction beam 30, and multiple positioning holes 470 are formed along the outer arc edge of the second arc-shaped plate 47. A through hole (not shown) is formed along the width direction of the traction beam 30. The positioning pin 45 passes through one positioning hole 470, the through hole, and another positioning hole 470 in sequence. A traction ring 48 is fixed to the side wall of the triangular shell 41 away from the traction beam 30.

[0031] Based on the existing technology for mobile vehicle traction height, rotating the triangular shell 41 causes the first arc-shaped plate 43 and connecting plate 44 to swing, selecting a suitable positioning hole 470 on the second arc-shaped plate 47 on the connecting plate 44. Positioning pins 45 are then passed sequentially through the positioning holes 470 of the connecting plates 44 on both sides and through the traction beam 30, rigidly constraining the angle of the triangular shell 41 to prevent loosening. The mobile vehicle traction hook is then connected to the traction ring 48 on the side wall of the triangular shell 41, and the mobile vehicle is started to drive the pump truck to the site.

[0032] Two strip-shaped fuel tanks 10 are arranged side by side and fixedly connected by multiple support plates 11 to form a rectangular chassis 12. A diesel engine and a water pump 20 are mounted on the top of the rectangular chassis 12, and the diesel engine is connected to the fuel tanks. A traction beam 30 is set at the bottom of the rectangular chassis 12, with a detachable connection to a mobile vehicle at the front end and wide-base wheels 32 driven by a drive shaft 31 at the rear end. This design disperses vibration loads through the overall frame, reduces local stress in the fuel tanks, avoids weld cracking and seal failure, and improves stability with the low center of gravity layout of the strip-shaped fuel tanks 10 and the rectangular chassis 12. The wide-base wheels 32 reduce the impact of lateral vibration. Compared with traditional suspended fuel tanks, this utility model fundamentally solves the safety hazards of fuel tanks under complex working conditions, and improves equipment reliability and emergency response efficiency.

[0033] The water pump 20 has an inlet pipe 22 and an outlet pipe 23. Both the inlet end of the inlet pipe 22 and the outlet end of the outlet pipe 23 are welded with fixed flanges 24. The pipeline is pre-installed with flanges, making connection simple and quick. The emergency mobile drainage pump truck also includes a rectangular shell 60, with the diesel engine housed inside. The rectangular shell 60 is fixed to the top of the rectangular chassis 12, and four lifting rings 61 are arranged in a matrix on the top wall of the rectangular shell 60 for easy lifting of the structure.

[0034] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
