Description

Technical Field

[0001] The utility model relates to the technical field of tank truck side protection, in particular to a tank truck side protection structure which can be turned upward. Background Art

[0002] The side protection structure of traditional tank trucks is fixed, that is, the upper and lower side guardrails are an integral structure, and the upper side guardrail cannot be flipped upward; when parking, it is not possible to determine whether the vehicle is safely parked by whether the upper side guardrail can be flipped upward. Utility Model Content

[0003] The purpose of the utility model is to provide a tank-type vehicle side protection structure that can be flipped upward, so as to solve the technical problems existing in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A side protection structure for a tank vehicle that can be flipped upward includes two parallel and opposite vertical connecting members, each of which is hingedly provided with an upper protection support member on its upper part and fixedly provided with a lower protection support member on its lower part. The two upper protection supports are connected to an upper side guardrail at one end away from the vertical connecting member, and the two lower protection supports are connected to a lower side guardrail at one end away from the vertical connecting member.

[0006] Furthermore, an upper connecting member is fixedly provided on the upper part of each of the two vertical connecting members, and the two upper connecting members are hinged to the two upper protective support members in a one-to-one correspondence.

[0007] Furthermore, a lower connecting member is fixedly provided at the lower portion of each of the two vertical connecting members, and the two lower connecting members are fixedly connected to the two lower protective support members in a one-to-one correspondence.

[0008] Furthermore, a cylinder connecting countersunk flange is fixedly provided on one of the upper connecting parts, and a cylinder is fixedly connected to the cylinder connecting countersunk flange, and the piston rod of the cylinder can freely shuttle between the corresponding upper connecting part and the upper protective support part.

[0009] Furthermore, the upper connecting member and the upper protective support member are both provided with piston rod shuttle holes for facilitating the free shuttle of the piston rod of the cylinder.

[0010] Furthermore, the upper connecting member is an upper connecting plate structure with a flange at the bottom to hold the upper protective support member.

[0011] Furthermore, the lower connecting member is a lower connecting plate structure with a flange at the bottom to hold the lower protective support member.

[0012] The working principle of the upward-flippable side protection structure for tank trucks provided by the utility model is as follows: first, it is connected to the chassis beam of the tank truck through two parallel and opposite vertical connecting parts, and then the cylinder is connected to the cab of the tank truck through an air circuit. Thereafter, when the tank truck is moving, the handbrake is released, so that the piston rod of the cylinder pops out and extends into the piston rod shuttle hole opened on the upper connecting part and the upper protection support. In this state, the upper side guardrail structure of the side protection structure of the utility model will be in a fixed state and cannot be flipped up; when the tank truck stops, the handbrake is pulled up. At this time, the piston rod of the cylinder will contract and withdraw from the piston rod shuttle hole opened on the upper connecting part and the upper protection support. In this state, the upper side guardrail structure of the side protection structure of the utility model can be flipped upward.

[0013] Compared with the prior art, the advantages of the present invention are as follows:

[0014] 1) Novel and flexible structure: the upper and lower guardrails are independent of each other and are not a whole. The lower guardrail is always fixed, while the upper guardrail can be fixed or flipped upwards;

[0015] 2) Easy to operate: After the vehicle stops and the parking brake is applied, you only need to use the latch to fix the upward-flipped side guardrail structure to proceed with subsequent operations;

[0016] 3) It can avoid the problem of rolling away and effectively improve the safety of the vehicle. This is because when the vehicle is parked, the handbrake must be pulled up before the upper side guardrail can be flipped up and subsequent operations can be carried out.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0035] The present invention will be further described below with reference to the accompanying drawings:

[0036] like Figures 1 to 9 As shown, an embodiment of the present invention provides a side protection structure for a tank vehicle that can be flipped upward, comprising two parallel and opposite vertical connecting members 1, the upper parts of the two parallel and opposite vertical connecting members 1 are respectively hingedly provided with an upper protection support member 2, and the lower parts are respectively fixedly provided with a lower protection support member 3, the two upper protection support members 2 are connected to an upper side guardrail 4 at one end away from the vertical connecting member 1, and the two lower protection support members 3 are connected to a lower side guardrail 5 at one end away from the vertical connecting member 1.

[0037] Specifically, in the above embodiment, an upper connecting member 6 is fixedly mounted on each of the two vertical connecting members 1, and the two upper connecting members 6 are hingedly connected to the two upper protective support members 2 in a one-to-one correspondence. More specifically, each upper connecting member 6 is connected to the corresponding upper protective support member 2 via a bolt 11, and each upper protective support member 2 can be flipped upward using the corresponding bolt 11 as a rotation axis.

[0038] Specifically, in the above embodiment, a lower connecting member 7 is fixedly provided at the lower portion of each of the two vertical connecting members 1 , and the two lower connecting members 7 are fixedly connected to the two lower protective support members 3 in a one-to-one correspondence.

[0039] Specifically, in the above embodiment, a cylinder connecting countersunk flange 8 is fixedly provided on one of the upper connecting parts 6, and a cylinder 9 is fixedly connected to the cylinder connecting countersunk flange 8, and the piston rod of the cylinder 9 can freely shuttle between the corresponding upper connecting part 6 and the upper protective support part 2.

[0040] More specifically, in the above embodiment, both the upper connecting member 6 and the upper protective support member 2 are provided with piston rod shuttle holes 10 that facilitate the free movement of the piston rod of the cylinder 9. When the piston rod of the cylinder 9 is inserted into the piston rod shuttle holes 10 of the upper connecting member 6 and the upper protective support member 2, the side guard rail portion of the upper portion of the side guard structure of the present invention is fixed and cannot be flipped upward. When the piston rod of the cylinder 9 is released from the piston rod shuttle holes 10 of the upper connecting member 6 and the upper protective support member 2, the side guard rail portion of the upper portion of the side guard structure of the present invention can be flipped upward.

[0041] More specifically, in the above embodiment, Figure 10 As shown, the upper connecting member 6 is an upper connecting plate structure with a flange at the bottom to hold the upper protective support member 2. Such a design can make the upper protective support member 2 only turn up and not turn down.

[0042] More specifically, in the above embodiment, Figure 11 As shown, the lower connecting member 7 is a lower connecting plate structure with a flange at the bottom to hold the lower protective support member 3.

[0043] More specifically, in the above embodiment, the vertical connector 1, the upper protective support 2 and the protective support 3 are preferably U-channel steel structures; the upper protective rail 4 and the lower protective rail 5 are preferably rectangular flat tube structures.

[0044] The working principle of the upward-turnable tank vehicle side protection structure provided by the utility model is as follows:

[0045] When using, Figure 12 and Figure 13 As shown, first connect the two parallel and opposite vertical connecting parts 1 to the chassis beam 12 of the tank truck, and then connect the cylinder 9 to the cab 13 of the tank truck through the air circuit. Then, when the tank truck is moving, release the handbrake, so that the piston rod of the cylinder 9 pops out and extends into the piston rod shuttle hole 10 opened on the upper connecting part 6 and the upper protective support 2. In this state, the upper side guardrail structure of the side protection structure of the utility model will be in a fixed state and cannot be flipped up; when the tank truck stops, pull up the handbrake. At this time, the piston rod of the cylinder 9 will shrink and withdraw from the piston rod shuttle hole 10 opened on the upper connecting part 6 and the upper protective support 2. In this state, the upper side guardrail structure of the side protection structure of the utility model can be flipped upward.

[0046] Finally, it should be noted that the above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
