Description

Technical Field

[0001] The present invention belongs to the technical field of oil tank trucks and relates to a highly safe oil tank truck. Background Art

[0002] An oil tank truck, also known as a mobile refueling truck, a computerized tax-controlled refueling truck, an oil drainage tank truck, an oil loading truck, an oil transportation truck, an oil hauling truck, a petroleum transportation truck, and an edible oil transportation truck, is mainly used for the transportation and storage of petroleum derivatives (such as gasoline, diesel, crude oil, lubricating oil, and coal tar).

[0003] Among them, a common oil tank truck mainly includes a vehicle body and an oil tank located on the vehicle body. The oil tank is mainly used for injecting and pumping out the contents, such as the most common gasoline. In order to repair and clean the oil tank, a ladder is usually vertically welded at the end of the vehicle body, and the top of the ladder is fixedly connected to the end of the oil tank, so that workers can climb up to the top of the oil tank through the ladder for operations, such as cleaning or repairing the top. In order to increase the capacity of the oil tank, the ladder is usually in a vertical form, so that the oil tank can have enough length while ensuring that the length of the entire oil tank truck is not too long. However, it is found in practice that the ladder is in a vertical state, so it is easy to lose grip or step on empty when climbing up, and the safety factor during use is relatively low. Summary of the Invention

[0004] The purpose of the present invention is to provide a highly safe oil tank truck, aiming to solve the problem of low safety factor.

[0005] To solve the above technical problems, the present invention provides a highly safe oil tank truck, including:

[0006] A vehicle body and a tank disposed on the vehicle body;

[0007] A climbing ladder, which includes two side rods and a plurality of horizontal rods horizontally connecting the two side rods. The side rods are in an L shape, and the top of the side rods is hinged to the top of one end of the tank;

[0008] A support plate, which is horizontally disposed on the top of the end of the vehicle body;

[0009] A hinge member, which is hinged to the support plate and includes a first state and a second state;

[0010] When the hinge member is in the first state, the bottom of the side rod is fixedly connected to the hinge member, and the bottom of the side rod and the hinge member are both in a vertical state;

[0011] When the hinge is in the second state, the bottom of the side rod and the hinge are both inclined, and the inclination direction of the hinge is opposite to that of the bottom of the side rod. The free end of the hinge is fixedly connected to the side rod, and the projection of the connection between the hinge and the side rod in the vertical direction is located outside the projection of the vehicle body in the vertical direction.

[0012] The present invention is further configured such that two hinge seats are oppositely arranged on the support plate, a linkage rod is horizontally rotatably arranged between the two hinge seats, the linkage rod is lower than the movement trajectory of the side rod, and two hinges are provided, and both of the two hinges are fixedly connected to the linkage rod.

[0013] The present invention is further configured such that the cross-section of the side rod is circular, the cross-section of the hinge is arc-shaped, and a positioning cylinder is movably sleeved on the side rod;

[0014] When the hinge is in the first state, the hinge fits on the side of the side rod away from the tank body, and the top of the hinge fits on the inner wall of the positioning cylinder, and the positioning cylinder is located between two of the horizontal rods.

[0015] The present invention is further configured such that a stabilizing member is provided on the outer wall of the side rod, the projection of the stabilizing member in the vertical direction coincides with the projection of the hinge in the vertical direction, the stabilizing member is higher than the hinge, the bottom of the stabilizing member fits on the inner wall of the positioning cylinder, the shape of the cross-section of the inner cavity of the positioning cylinder is a first shape, and the shape of the common cross-section of the stabilizing member and the side rod connected to the stabilizing member is a second shape, and the first shape is matched with the second shape.

[0016] The present invention is further configured such that a magnetic body that can be magnetically attracted to the positioning cylinder is provided at the top of the stabilizing member. When the positioning cylinder and the magnetic body are magnetically attracted, the positioning cylinder and the hinge are in a separated state.

[0017] The present invention is further configured such that a positioning groove is vertically opened at the bottom of the positioning cylinder, a positioning rod is horizontally arranged on the side of the side rod close to the tank body, one end of the positioning rod is located in the positioning groove, a positioning nut is threadedly connected to the free end of the positioning rod, an anti-disengagement portion is provided on the outer side of the bottom of the positioning cylinder, the positioning nut is higher than the anti-disengagement portion, and the projection of the positioning nut in the vertical direction coincides with the projection of the anti-disengagement portion in the vertical direction.

[0018] The present invention is further configured such that an L-shaped connecting member is provided on the side of the side rod close to the tank body, a connecting hole is opened at the free end of the hinge, and the diameter of the connecting hole is larger than the diameter of the connecting member;

[0019] When the hinge is in the second state, the connecting piece passes through the connecting hole from bottom to top, the positioning nut is threadedly connected to the connecting piece, the positioning nut abuts against the inner wall of the hinge, and the end of the hinge abuts against the lower side of the side rod.

[0021] Compared with the prior art, the present invention provides a highly safe oil tanker. When the climbing ladder is not in use, the climbing ladder is in the first state, that is, the climbing ladder is in a vertical state. Therefore, the overall length of the oil tanker at this time meets the required manufacturing and use conditions and can have a relatively small total length. Then, when it is necessary to climb to the top of the tank body for maintenance or cleaning, first disconnect the connection between the hinge and the side rod, and then rotate the hinge and the side rod outward respectively. After rotating to an appropriate angle, fixedly connect the side rod and the hinge. At this time, the side rod and the hinge maintain the shape stability under the principle of the triangle. In this way, when the worker climbs to the top of the tank body, the climbing ladder can provide normal support. Since the climbing ladder is not in a vertical state at this time, but in an inclined state towards the tank body, the climbing difficulty and climbing safety of the worker are improved during the climbing process.

Specific embodiments

[0035] The following further describes in detail a highly safe oil tanker proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present invention. The same or similar reference numerals in the drawings represent the same or similar components.

[0036] A highly safe oil tanker, as Figures 1 to 12 shown, includes:

[0037] A vehicle body 1 and a tank body 2 provided on the vehicle body 1;

[0038] A climbing ladder 3, the climbing ladder 3 includes two side rods 3a and a plurality of horizontal rods 3b horizontally connected to the two side rods 3a, the side rods 3a are L-shaped, and the top of the side rods 3a is hinged to the top of one end of the tank body 2;

[0039] A support plate 4, the support plate 4 is horizontally arranged on the top of the end of the vehicle body 1;

[0040] A hinge 5, wherein the hinge 5 is hinged to the support plate 4, and the hinge 5 includes a first state and a second state;

[0041] When the hinge 5 is in the first state, the bottom of the side rod 3a is fixedly connected to the hinge 5, and the bottom of the side rod 3a and the hinge 5 are both vertical;

[0042] When the hinge 5 is in the second state, the bottom of the side rod 3a and the hinge 5 are both inclined, and the inclination direction of the hinge 5 is opposite to the inclination direction of the bottom of the side rod 3a, the free end of the hinge 5 is fixedly connected to the side rod 3a, and the projection of the connection between the hinge 5 and the side rod 3a in the vertical direction is located outside the projection of the vehicle body 1 in the vertical direction.

[0043] Two hinge seats 6 are relatively arranged on the support plate 4, and a linkage rod 7 is horizontally rotated between the two hinge seats 6. The linkage rod 7 is lower than the movement trajectory of the side rod 3a. Two hinge parts 5 are arranged, and both of the two hinge parts 5 are fixedly connected to the linkage rod 7.

[0044] The cross section of the side rod 3a is circular, the cross section of the hinge 5 is arc-shaped, and a positioning cylinder 8 is movably sleeved on the side rod 3a;

[0045] When the hinge 5 is in the first state, the hinge 5 is attached to the side of the side rod 3a away from the tank body 2, and the top of the hinge 5 is attached to the inner wall of the positioning tube 8, and the positioning tube 8 is located between two of the horizontal rods 3b.

[0046] A stabilizing member 9 is provided on the outer wall of the side rod 3a, and the projection of the stabilizing member 9 in the vertical direction coincides with the projection of the hinge 5 in the vertical direction. The stabilizing member 9 is higher than the hinge 5, and the bottom of the stabilizing member 9 is attached to the inner wall of the positioning tube 8. The shape of the cross section of the inner cavity of the positioning tube 8 is a first shape, and the shape of the common cross section of the stabilizing member 9 and the side rod 3a connected to the stabilizing member 9 is a second shape, and the first shape matches the second shape. A magnetic body 10 that can be magnetically attracted to the positioning tube 8 is provided on the top of the stabilizing member 9. When the positioning tube 8 is magnetically attracted to the magnetic body 10, the positioning tube 8 and the hinge 5 are in a separated state.

[0047] A positioning groove 11 is vertically formed at the bottom of the positioning cylinder 8. A positioning rod 12 is horizontally arranged on one side of the side rod 3a close to the tank body 2. One end of the positioning rod 12 is located in the positioning groove 11. A positioning nut is threadedly connected to the free end of the positioning rod 12. An anti-disengagement portion 13 is arranged on the outer side of the bottom of the positioning cylinder 8. The positioning nut is higher than the anti-disengagement portion 13, and the projection of the positioning nut in the vertical direction coincides with the projection of the anti-disengagement portion 13 in the vertical direction.

[0048] An L-shaped connecting member 14 is arranged on one side of the side rod 3a close to the tank body 2. A connecting hole 15 is formed at the free end of the hinge member 5. The diameter of the connecting hole 15 is larger than the diameter of the connecting member 14.

[0049] When the hinge member 5 is in the second state, the connecting member 14 passes through the connecting hole 15 from bottom to top. The positioning nut is threadedly connected to the connecting member 14. The positioning nut abuts against the inner wall of the hinge member 5. The end of the hinge member 5 abuts against the lower side of the side rod 3a.

[0050] Two hinge cylinders 16 are coaxially arranged on the tank body 2. One hinge rod 17 is horizontally arranged on the outer side of each of the two side rods 3a. The two hinge rods 17 are respectively movably attached to the inner walls of the two hinge cylinders 16.

[0051] A highly safe oil tanker provided by the present invention, when the climbing ladder 3 is not in use, the climbing ladder 3 is in the first state at this time, that is, the climbing ladder 3 is in a vertical state. Therefore, the overall length of the oil tanker at this time meets the required manufacturing and use conditions and can have a relatively small total length. Then when it is necessary to climb to the top of the tank body 2 for maintenance or cleaning, first disconnect the connection between the hinge member 5 and the side rod 3a, and then rotate the hinge member 5 and the side rod 3a outwards respectively. After rotating to an appropriate angle, fixedly connect the side rod 3a and the hinge member 5. At this time, the side rod 3a and the hinge member 5 maintain the shape stability under the triangle principle. In this way, when the worker climbs to the top of the tank body 2, the climbing ladder 3 can provide normal support. Since the climbing ladder 3 is not in a vertical state at this time, but in an inclined state towards the tank body 2, the climbing difficulty and climbing safety of the worker are improved during the climbing process.

[0052] Among them, when the climbing ladder 3 needs to be used, first rotate the positioning nut and remove the positioning nut from the positioning rod 12. At this time, the positioning cylinder 8 can be directly lifted upwards until the top of the positioning cylinder 8 is magnetically attracted to the magnetic body 10. Then the hinge member 5 is in a free state, and the same operation is performed on the other positioning cylinder 8.

[0053] After rotating an articulated member 5 outwards, it is possible to drive the articulated member 5 on the other side to rotate outwards through the linkage rod 7; after rotating to a certain angle, rotate the side rod 3a outwards. When the side rod 3a rotates to a large angle, then rotate the articulated member 5 in the reverse direction so that the free end of the articulated member 5 is located inside the side rod 3a; then also rotate the side rod 3a in the reverse direction so that the lower side of the side rod 3a fits on the free end of the articulated member 5; then rotate the articulated member 5 outwards again. At this time, the articulated member 5 rotates downwards in a way that fits on the side rod 3a until finally the connecting member 14 passes through the connecting hole 15 from bottom to top, and the lower side of the articulated member 5 abuts against the bent portion of the connecting member 14. Finally, thread the positioning nut onto the connecting member 14, which ensures the stability of the connection between the articulated member 5 and the connecting member 14. The diameter of the connecting hole 15 is larger than the cross-section of the connecting member 14, so that the connecting member 14 can pass through the connecting hole 15 normally. At the same time, the diameter of the connecting hole 15 is smaller than the diameter of the positioning nut, so that the positioning nut can normally limit the articulated member 5.

[0054] After the positioning nut is connected, the articulated member 5 is in the second state at this time and can normally climb up or down the climbing ladder 3. And because the articulated member 5 is arc-shaped, it has greater strength, can better prevent deformation, and further improves the use safety.

[0055] After use, remove the positioning nut from the connecting member 14, then rotate the articulated member 5 upwards so that the connecting member 14 is separated from the connecting hole 15, then rotate the side rod 3a upwards. When the connecting member 14 does not affect the rotation of the articulated member 5, rotate the articulated member 5 outwards so that the articulated member 5 does not affect the rotation of the side rod 3a, and then the side rod 3a can be rotated until the side rod 3a abuts against the end of the tank body 2. Finally, rotate the articulated member 5 upwards so that the articulated member 5 fits vertically on the bottom of the side rod 3a; the stabilizing member 9 is higher than the top of the articulated member 5, so the stabilizing member 9 does not affect the normal rotation of the articulated member 5;

[0056] Then move the positioning cylinder 8 downwards. The positioning cylinder 8 transitions from the stabilizing member 9 to the articulated member 5; until finally the bottom of the positioning cylinder 8 abuts against one of the horizontal rods 3b, and at this time the positioning rod 12 also enters the positioning groove 11. Connect the positioning nut to the positioning rod 12. Since the anti-detachment portion 13 can limit the positioning cylinder 8, the positioning cylinder 8 can stably fix the positions of the articulated rod 17 and the side rod 3a at this time, and thus also ensures the position stability of the climbing ladder 3 and the articulated rod 17.

[0057] The first shape and the second shape are matched, and the tops of the final positioning cylinder 8 are all attached to the outer wall of the stabilizing member 9. Therefore, during the process of moving the positioning cylinder 8 downward, the angle of the positioning cylinder 8 is fixed, and the fixed positioning cylinder 8 can be stably connected to the hinge member 5. At the same time, the positioning rod 12 can also stably enter the positioning groove 11, ensuring the convenience of operation.

[0058] The positioning nut can be used for the positioning of both the positioning cylinder 8 and the hinge member 5, and the usage cost is lower. At the same time, the two usage situations are the first state and the second state, which can also effectively prevent the positioning nut from being lost. During the process of transitioning from the second state to the first state, the positioning cylinder 8 is positioned by the magnetic body 10. Therefore, when the worker connects the positioning cylinder 8 and the hinge member 5, there is no need to move the positioning cylinder 8 upward and then downward, but only to move the positioning cylinder 8 downward directly, which is simple and convenient.

[0059] The top of the side rod 3a is hinged to the hinge cylinder 16 on the tank body 2 through the hinge rod 17, which reduces the interference between the two side rods 3a and improves the usage situation. At the same time, the hinge cylinder 16 is located outside the two side rods 3a, improving the position stability and usage stability of the entire climbing ladder 3.

[0060] It should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other.
