Water cart without beam structure

Abstract

This application relates to the field of water transport vehicle technology, and in particular to a water transport vehicle with a beamless structure, including a vehicle chassis, a subframe, and a tank. The subframe is arranged along the length of the vehicle chassis, and the sides of the subframe and the sides of the vehicle chassis are connected and fixed by multiple sets of fixing components. Multiple irregularly shaped bases are welded to the bottom of the tank, arranged at intervals, perpendicular to the length of the tank. The bottom of the irregularly shaped bases is fixed to the two sides of the subframe by multiple sets of bolts. The height difference between the bottom of the tank and the top surface of the vehicle chassis is between 200-250 mm, formed by the irregularly shaped bases and the subframe. This beamless water transport vehicle increases the height of the tank relative to the vehicle chassis, ensuring that the bottom of the tank is at least 200-250 mm higher than the vehicle chassis, significantly increasing the height space between them. This facilitates later maintenance, and the overall connection is very robust and secure, making it suitable for harsh environments and poor road conditions abroad.

Description

Technical Field

[0001] This application relates to the field of water transport vehicle technology, and in particular to a water transport vehicle with a beamless structure. Background Technology

[0002] Water trucks, also known as water supply trucks or water tankers, are specialized transport vehicles with a core structure consisting of a car chassis, water inlet / outlet systems, and a tank. They are primarily used for transporting and spraying hot water, drinking water, and other water bodies. Their functions cover engineering water supply, drought relief, fire emergency response, and environmental sanitation. They can be equipped with optional devices such as water pumps, fire hose connections, and corrosion protection facilities, and are categorized into landscaping, engineering, and fire protection types.

[0003] For example, Chinese patent application number CN202022812143.6 discloses a split-type frame for a semi-trailer, in which the tank sub-beam is welded to the tank, the traveling frame is connected to the traveling part, and the tank sub-beam is connected to the traveling frame by mounting bolts.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Water tankers typically require welded sub-beams to their tanks. Since the bottom of the tank is generally an arc shape, the sub-beams run parallel to the length of the tank and are located on either side of the tank. They are then directly or indirectly fixed to the vehicle chassis. This means the bottom of the tank is much lower than the sub-beams, resulting in a very small height gap between the tank and the vehicle chassis. This makes maintenance difficult and the overall connection not robust enough, making it unsuitable for harsh environments and poor road conditions abroad. Utility Model Content

[0006] This application provides a water truck with a beam-less structure to improve the following technical problems:

[0007] Common water tankers typically require welded sub-beams on their tanks, and the bottom of the tank is very close to the vehicle chassis. The height space between the two is very small, making it inconvenient for later maintenance. Moreover, the overall connection is not strong enough, making it unsuitable for harsh environments and poor road conditions abroad.

[0008] This application provides a water truck with a beamless structure, employing the following technical solution:

[0009] A water transport vehicle with a beamless structure includes a vehicle chassis, a subframe, and a tank. The subframe is arranged along the length of the vehicle chassis. The sides of the subframe and the sides of the vehicle chassis are connected and fixed by multiple sets of fixing components. The bottom of the tank is welded with multiple irregularly shaped bases arranged at intervals. The irregularly shaped bases are arranged perpendicular to the length of the tank. The bottom of the irregularly shaped bases and the two sides of the subframe are fixedly connected by multiple sets of bolts. The height difference between the bottom of the tank and the top surface of the vehicle chassis is between 200-250 mm, and the height difference is formed by the irregularly shaped bases and the subframe.

[0010] In one feasible technical solution of this application, the width of the irregularly shaped base is between 180-220 mm, and there are at least four irregularly shaped bases, two of which are located in front of and behind the wheel of the vehicle chassis, respectively, and the other two are located at the front end and rear end of the vehicle chassis, respectively.

[0011] In one feasible technical solution of this application, the upper surface of the irregularly shaped base is configured as a concave arc surface, which is used to adapt to and fit the arc surface of the bottom of the tank. The bottom of the irregularly shaped base is provided with a horizontal surface, and the two sides of the horizontal surface are provided with oblique cut surfaces that slope outward and upward.

[0012] In one feasible technical solution of this application, a first plate arranged horizontally is welded and fixed on the horizontal plane, and a second plate and a third plate are welded and fixed on the upper surfaces of the two sides of the subframe, respectively. One side of the first plate is attached to the second plate and the two are fixedly connected by multiple sets of first bolts, and the other side of the first plate is attached to the third plate and the two are fixedly connected by multiple sets of second bolts.

[0013] In one feasible technical solution of this application, the subframe includes a first side beam and a second side beam arranged in parallel at intervals, and a plurality of longitudinal beams arranged at intervals are vertically connected between the first side beam and the second side beam. The first plate is connected to the first side beam, and the second plate is connected to the second side beam.

[0014] In one feasible technical solution of this application, the first bolt group is provided with at least six groups, of which four groups of the first bolt group are located on the outer side of the first side beam and at least two groups of the first bolt group are located on the inner side of the first side beam; the second bolt group is provided with at least six groups, of which four groups of the second bolt group are located on the outer side of the second side beam and at least two groups of the second bolt group are located on the inner side of the second side beam.

[0015] In one feasible technical solution of this application, the fixing component includes a U-shaped rod, two fixing seats and two locking nuts. The two ends of the U-shaped rod are set as threaded sections. The two fixing seats are respectively welded and fixed to the two sides of the first side beam or the two sides of the second side beam. The threaded sections pass through the fixing seats and are threadedly assembled to the locking nuts. The side beam of the vehicle chassis passes through the U-shaped rod and is clamped between the bottom of the U-shaped rod and the bottom of the subframe.

[0016] In one feasible technical solution of this application, the first side beam, the second side beam and the longitudinal beam are all square steel tubes, and the first plate, the second plate and the third plate are all steel plates.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] The auxiliary beam structure on the tank body has been eliminated. The tank body is mainly connected and fixed to the vehicle chassis through an irregularly shaped base and a subframe, which raises the height of the tank body relative to the vehicle chassis. This ensures that the bottom of the tank body is at least 200-250 mm higher than the vehicle chassis, significantly increasing the height space between the two. This facilitates later maintenance, and the overall connection is very strong and secure, making it suitable for harsh environments and poor road conditions abroad. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a water truck with a beam-less structure. (Refer to...) Figure 1-3The water transport vehicle without a subframe structure includes a vehicle chassis 1, a subframe 2, and a tank body 3. The subframe 2 is arranged along the length of the vehicle chassis 1. The sides of the subframe 2 and the sides of the vehicle chassis 1 are connected and fixed by multiple sets of fixing components 4. Multiple irregularly shaped bases 5 are welded to the bottom of the tank body 3 at intervals. The irregularly shaped bases 5 are arranged perpendicular to the length of the tank body 3. The bottom of the irregularly shaped bases 5 and the two sides of the subframe 2 are fixedly connected by multiple sets of bolts. The height difference between the bottom of the tank body 3 and the top surface of the vehicle chassis 1 is between 200-250 mm, and the height difference is formed by the irregularly shaped bases 5 and the subframe 2. The height of the subframe 2 is about 140 mm, and the height of the bottom of the irregularly shaped bases 5 is about 80 mm, that is, the above-mentioned height difference is preferably 220 mm.

[0040] In this embodiment, the irregular base 5 is welded from multiple steel plates, and the width of the irregular base 5 is between 180-220 mm. There are at least four irregular bases 5, two of which are located in front of and behind the wheel of the vehicle chassis 1, respectively, and the other two are located at the front end and rear end of the vehicle chassis 1, respectively.

[0041] In one feasible technical solution of this application, the upper surface of the irregular base 5 is set as a concave arc surface 51, which is used to adapt to and fit the arc surface of the bottom of the tank 3. The bottom of the irregular base 5 is provided with a horizontal surface 52, and the two sides of the horizontal surface 52 are provided with inclined cut surfaces 53 that slope outward and upward.

[0042] To achieve a secure connection between the irregularly shaped base 5 and the subframe 2, a first flat plate 6 arranged horizontally is welded and fixed on the horizontal plane 52. A second flat plate 7 and a third flat plate 8 are welded and fixed on the upper surfaces of both sides of the subframe 2, respectively. One side of the first flat plate 6 is in contact with the second flat plate 7 and the two are fixedly connected by multiple sets of first bolts 9. The other side of the first flat plate 6 is in contact with the third flat plate 8 and the two are fixedly connected by multiple sets of second bolts 10. The first flat plate 6, the second flat plate 7 and the third flat plate 8 are all steel plates.

[0043] The subframe 2 includes a first side beam 21 and a second side beam 22 arranged in parallel at intervals. Multiple longitudinal beams 23 are vertically connected between the first side beam 21 and the second side beam 22. A first flat plate 6 is connected to the first side beam 21, and a second flat plate 7 is connected to the second side beam 22. The first side beam 21, the second side beam 22, and the longitudinal beams 23 are all made of square steel tubing. The subframe 2 designed above is simple and robust in structure, lightweight, easy to manufacture, and low in cost. It is also convenient to connect and fix, and easier to assemble.

[0044] In this embodiment, in order to further improve the connection between the irregular base 5 and the subframe 2, at least six sets of first bolt groups 9 are provided, of which four sets of first bolt groups 9 are located on the outer side of the first side beam 21 and at least two sets of first bolt groups 9 are located on the inner side of the first side beam 21; at least six sets of second bolt groups 10 are provided, of which four sets of second bolt groups 10 are located on the outer side of the second side beam 22 and at least two sets of second bolt groups 10 are located on the inner side of the second side beam 22.

[0045] In this embodiment, the fixing component 4 includes a U-shaped rod 41, two fixing seats 42, and two locking nuts 43. The two ends of the U-shaped rod 41 are threaded sections. The two fixing seats 42 are welded and fixed to both sides of the first side beam 21 or both sides of the second side beam 22, respectively. The threaded sections pass through the fixing seats 42 and are threaded onto the locking nuts 43. The side beams of the vehicle chassis 1 pass through the U-shaped rod 41 and are clamped between the bottom of the U-shaped rod 41 and the bottom of the subframe 2. The fixing component 4 designed above is simple and robust in structure, easy to manufacture and low in cost, and facilitates connection, fixing, and assembly.

[0046] The beneficial technical effects of the beamless water truck in this application embodiment are roughly as follows:

[0047] The sub-beam structure on the tank body 3 has been eliminated. The tank body 3 is mainly connected and fixed to the vehicle chassis 1 through the irregular base 5 and the sub-frame 2. This raises the height of the tank body 3 relative to the vehicle chassis 1, so that the bottom of the tank body 3 is at least 1200-250 mm higher than the vehicle chassis. This significantly increases the height space between the two, which facilitates later maintenance. Moreover, the overall connection is very strong and secure, making it suitable for harsh environments and poor road conditions abroad.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
