[0028] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] With the continuous development of industrial technology, tank trucks, as an important means of logistics and transportation, are increasingly widely used in chemical, metallurgical and other fields. In the electrolytic aluminum industry, the feeding desulfurization workshop also uses tank trucks to transport raw materials. However, during the unloading process, due to tire wear, improper maintenance and other reasons, the risk of tire explosion always exists, posing a serious threat to the safety of operators. Traditional tank truck protective devices are often designed for tank truck transportation collisions. For example, the rear protective device of a hazardous goods transport tank truck is to protect the safety of the pipe body in a rear-end collision accident and avoid secondary disasters such as leakage, pollution, combustion, and explosion caused by damage to the tank truck. The relevant technology does not design protective devices for tank truck unloading.

[0030] In order to solve the above technical problems, this application proposes a unloading safety protection device, please refer to Figure 1-Figure 2 , Figure 1 This is a schematic diagram of an unloading safety protection device in a storage state according to an embodiment of the present application. Figure 2 This is a schematic diagram of an unloading safety protection device of an embodiment of the present application in use, wherein the unloading safety protection device includes a base 10 and a protection assembly 20, wherein the base 10 includes a first supporting member 11, and the protection assembly 20 includes a fixedly connected protection member 21 and a second supporting member 22, and the protection member 21 is rotatably connected to the first supporting member 11. In an embodiment of the present application, the unloading safety protection device has a storage state and a use state, wherein, in the storage state, the protective member 21 can be flipped in a direction close to the first carrier 11 and remain in contact with the first carrier 11, so that the operator can move and store the unloading safety protection device; in the use state, the protective member 21 can be flipped in a direction away from the first carrier 11, so that the second carrier 22 is in contact with the ground. At this time, the protective member 21 will be vertically arranged between the first carrier 11 and the second carrier 22. In this way, in the use state, the tank truck can be stably parked on the second carrier 22, and the operator stands on the first carrier 11 to operate, and the protective member 21 forms an effective protective barrier between the operator and the tank truck, effectively preventing the tank truck's tires from bursting and causing harm to the operator.

[0031] Continue to see Figure 1 The base 10 includes a first bearing member 11 and a sliding mechanism 12, and the first bearing member 11 and the sliding mechanism 12 jointly support and move the entire device.

[0032] Specifically, see Figure 1-Figure 3 , Figure 3This is a side view schematic diagram of an unloading safety protection device of an embodiment of the present application in the use state. In the embodiment of the present application, the first bearing member 11 is used to carry the operator, and the first bearing member 11 has a manning board 111 for the operator to stand, a first rotating part 112 and a first fixed part 113. Among them, the first rotating part 112 is connected to the manning board 111, and the first rotating part 112 is arranged at one end of the first bearing member 11 close to the protective member 21, and the first fixed part 113 is connected to the manning board 111. In the embodiment of the present application, the surface of the manning board 111 can be anti-slip treated, for example, spraying anti-slip paint on the manning board 111, or setting anti-slip strips, to prevent the operator from slipping during the unloading operation.

[0033] In addition, in the embodiment of the present application, the first bearing member 11 further includes a guardrail 114, which is used to prevent the operator from accidentally falling during operation. In this embodiment, the guardrail 114 is detachably connected to the manned board 111, or the guardrail 114 is fixedly connected to the manned board 111.

[0034] It can be understood that if the operator's use requirement is to flexibly install or remove the guardrail 114, the guardrail 114 and the manned board 111 are connected in a detachable manner. Further, the detachable connection between the guardrail 114 and the manned board 111 includes at least one of a snap connection, a screw connection, and an interference fit. If the operator's use requirement is to effectively ensure the operator's safety, the guardrail 114 and the manned board 111 are fixedly connected. Further, the fixed connection between the guardrail 114 and the manned board 111 can be welding, or riveting, etc.

[0035] The sliding mechanism 12 is arranged at the bottom of the first carrier 11, and is used to move the unloading safety protection device. In the embodiment of the present application, the sliding mechanism 12 includes a sliding component 121 and a locking component 122, wherein the sliding component 121 is connected to the manned board 111, and the locking component 122 is connected to the sliding component 121. It can be understood that the sliding component 121 allows the manned board 111 and the unloading safety protection device to slide smoothly and steadily in the workshop, while the locking component 122 can fix the manned board 111 and the unloading safety protection device at a specified position to prevent the device from displacement or sliding.

[0036] Preferably, the sliding component 121 can be at least one of a pulley, a universal wheel, and a ball bearing to facilitate the operator to adjust the position of the unloading safety protection device. For example, the sliding component 121 uses a universal wheel, and a universal wheel is installed at each of the four corners of the manning board 111.

[0037] See also Figure 2 In the embodiment of the present application, the protection assembly 20 includes a protection member 21 and a second supporting member 22 that are fixedly connected.

[0038] In the embodiment of the present application, the protective member 21 is relatively rotatably connected to the first bearing member 11, and the protective member 21 includes a protective layer plate 211, a buffer layer 212, a second rotating portion 213, and a second fixed portion 214. The buffer layer 212 is wrapped around the protective layer plate 211, the second rotating portion 213 is connected to the protective layer plate 211, and the second rotating portion 213 is disposed at one end of the protective member 21 close to the first bearing member 11.

[0039] Preferably, the protective layer plate 211 can be a metal plate, for example, a 2 mm steel plate is used as the protective layer plate 211. It can be understood that in the embodiment of the present application, the protective layer plate 211 is used to form a protective barrier when the tank truck tire bursts to prevent the operator from suffering impact injuries or debris splashing injuries. Therefore, the protective layer plate 211 is required to have a certain strength. Furthermore, the buffer layer 212 can be made of soft materials such as rubber and foam plastics. It can be understood that when the tank truck tire bursts, if there is debris splashing and contacting the buffer layer 212, the buffer layer 212 can absorb the impact potential energy of the residue to prevent it from continuously rebounding and splashing to other locations to cause damage.

[0040] Further, in the embodiment of the present application, the first rotating part 112 and the second rotating part 213 are rotationally matched, so that the protective member 21 can be relatively rotatably connected to the first supporting member 11. Specifically, the first rotating part 112 and the second rotating part 213 can be rotatably connected by a rotating shaft-shaft hole. As a feasible implementation mode, the first rotating part 112 is a rotating shaft, and the second rotating part 213 is a shaft hole, wherein the first rotating part 112 is rotationally connected in the second rotating part 213, so that the protective member 21 is rotationally connected to the first supporting member 11. As another feasible implementation mode, the first rotating part 112 is a shaft hole, and the second rotating part 213 is a rotating shaft, wherein the second rotating part 213 is rotationally connected in the first rotating part 112, so that the protective member 21 is rotationally connected in the first supporting member 11.

[0041] Furthermore, in the embodiment of the present application, in the storage state, the first fixing portion 113 can cooperate with the second fixing portion 214, so that the protective member 21 and the first carrier 11 are kept in close contact and storage. It can be understood that in the embodiment of the present application, there are multiple ways of cooperating and connecting the first fixing portion 113 and the second fixing portion 214. For example, a through hole is provided on each of the first fixing portion 113 and the second fixing portion 214. In the storage state, the two through holes can be penetrated by bolts to make the first fixing portion 113 and the second fixing portion 214 cooperate. For another example, Figure 1-Figure 2 As shown, the first fixing portion 113 is a buckle, and the second fixing portion 214 is a limiting protrusion. In the storage state, the buckle and the limiting protrusion are engaged with each other, so that the first fixing portion 113 and the second fixing portion 214 are engaged with each other.

[0042] Continue reading Figure 2In the embodiment of the present application, the second bearing member 22 is fixedly connected to the protective member 21. Further, the second bearing member 22 is connected to the protective member 21 at an angle. It can be understood that when the second bearing member 22 is connected to the protective member 21 at an angle, it can be realized that when the protective member 21 is flipped in a direction away from the first bearing member 11 and vertically arranged between the first bearing member 11 and the second bearing member 22 in the use state, the second bearing member 22 contacts the ground. Preferably, the angle between the second bearing member 22 and the protective member 21 is 90°.

[0043] Furthermore, the second bearing member 22 includes a carrier plate 221 and an anti-skid layer 222, wherein the carrier plate 221 is connected to the protective layer plate 211 for stopping the tank truck. Preferably, the carrier plate 221 is a metal plate, for example, a 2 mm steel plate is used as the carrier plate 221. It should be noted that the second bearing member 22 is clamped between the tank truck and the ground when in use. This structure can effectively prevent the protective member 21 from being overturned when the tire explodes, thereby ensuring the stability and safety of the unloading safety protection device. Therefore, in order to ensure the connection strength between the second bearing member 22 and the protective member 21, in the embodiment of the present application, the carrier plate 221 is fixedly connected to the protective layer plate 211, and the two are fixedly connected by welding or an integrally formed structure.

[0044] Furthermore, in the embodiment of the present application, a guide slope is provided at the edge of the vehicle loading plate 221, wherein the guide slope is used to guide the tanker onto the second load-bearing member 22. A gripping portion 2211 is provided at one end of the vehicle loading plate 221 away from the protective layer plate 211. In the embodiment of the present application, the gripping portion 2211 is used for a person to hold in the storage state, so that the operator can move the unloading safety protection device. In the embodiment of the present application, the gripping portion 2211 can be a handle, or can be set as a gripping plate extending outward from the edge of the vehicle loading plate 221.

[0045] Furthermore, in the embodiment of the present application, the anti-slip layer 222 can be an anti-slip material, such as a rubber layer or an anti-slip paint layer, or it can be a structure with an anti-slip function, for example, the upper surface of the vehicle loading plate 221 extends upward to form an anti-slip protrusion.

[0046] It should be noted that when using the unloading safety protection device in the embodiment of the present application, the operator pushes the unloading safety protection device in the storage state to the designated position, and switches the unloading safety protection device to the use state by rotating the protective member 21, and then guides the tank truck to travel and stop on the second support member 22, and keeps the rear tires of the tank truck on the second support member 22. At this time, after the operator stands on the first support member 11, the protective member 21 can form a protective barrier between the operator and the rear tires of the tank truck, thereby protecting the safety of the operator.
