Description

Technical Field

[0001] The present invention belongs to the technical field of transportation pallets, and particularly relates to a hazardous waste transportation pallet with a leak-proof function. Background Art

[0002] With the development of industry, the amount of hazardous waste liquid discharged during industrial production processes is increasing day by day. Directly discharging the hazardous waste liquid into the environment easily causes environmental pollution. To reduce the environmental pollution caused by the hazardous waste liquid, it is necessary to harmlessly treat the hazardous waste liquid generated during industrial production processes.

[0003] In the prior art, for the harmless treatment of hazardous waste liquid, it is usually necessary to load the hazardous waste liquid into a storage barrel, and then transport the storage barrel to a hazardous waste treatment station for harmless treatment. A transportation pallet is required during the transportation of the storage barrel.

[0004] Existing transportation pallets are generally pallet structures used in cooperation with forklifts. By directly placing a storage barrel storing hazardous waste liquid on the transportation pallet, during the transportation of the transportation pallet carrying the storage barrel, it is easy for the hazardous waste liquid in the storage barrel to overflow from the closed cover due to shaking or vibration. The overflowing hazardous waste liquid will not only pollute the transportation pallet but also contaminate the transportation carriage, which is not conducive to the safe transportation of hazardous waste liquid. Therefore, we provide a hazardous waste transportation pallet with a leak-proof function to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a hazardous waste transportation pallet with a leak-proof function. Through the specific structural design of the barrel positioning component, the rotation linkage component, the leak-proof component, and the barrel supporting component, the problem that existing transportation pallets lack a leak-proof function is solved.

[0006] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a hazardous waste transportation pallet with a leak-proof function, including a barrel positioning component. A rotation linkage component is installed on the barrel positioning component, and a leak-proof component coaxial with it is arranged above the rotation linkage component. Among them, the barrel positioning component includes a plurality of barrel positioning parts arranged circumferentially and connected by torsion springs. The barrel positioning parts are used to tightly press against the outer wall of the hazardous waste barrel to achieve the positioning of the hazardous waste barrel. The rotation linkage component is coaxially arranged with the barrel positioning component, and the rotation linkage component is used to realize the synchronous rotation of a plurality of circumferentially arranged barrel positioning parts. The leak-proof component includes a locking part and a leak-proof part. The locking part is arranged corresponding to the barrel positioning part one by one and the two are inserted and matched. The leak-proof part is sleeved on the hazardous waste barrel and is used to collect the leaked hazardous waste liquid.

[0007] In some embodiments, the barrel positioning assembly further includes a hollow ring seat. A plurality of limiting members are fixedly arranged on the peripheral side of the hollow ring seat. An annular reinforcing plate coaxial with the hollow ring seat is arranged above the hollow ring seat. A plurality of flow-through connectors communicating with the inner cavity thereof are installed at the top of the hollow ring seat.

[0008] In some embodiments, the barrel positioning portion includes a support shaft connected to the inner side of the hollow ring seat through a torsion spring. The annular reinforcing plate is rotatably connected to each support shaft. A first positioning member and a second positioning member are respectively fixedly installed on the peripheral side of the support shaft. The first positioning member is located below the annular reinforcing plate, and the second positioning member is located above the annular reinforcing plate. A guiding channel is formed at the top of the first positioning member. A shifting rod is slidably arranged inside the guiding channel. A locking rod is fixedly arranged at the top of the second positioning member.

[0009] In some embodiments, the rotation linkage assembly includes a rotation linkage ring. A plurality of linkage ports are circumferentially arranged at the top of the rotation linkage ring. The linkage ports are arranged in one-to-one correspondence with the shifting rods. The shifting rods are inserted and matched inside the corresponding linkage ports. An elastic element connected to the corresponding shifting rod is arranged inside the guiding channel. A guiding member corresponding to the barrel positioning portion is fixedly arranged on the peripheral side of the rotation linkage ring.

[0010] In some embodiments, the locking portion includes a vertically arranged support rod. A locking tube is fixedly arranged at the bottom of the support rod. The locking tube is inserted and matched with the locking rod below it; the leak-proof portion includes an annular limiting seat for sleeving on the hazardous waste barrel. An annular installation cavity is formed on the inner wall of the annular limiting seat. An annular elastic ring is installed inside the annular installation cavity. A flow-through connection pipe corresponding to the flow-through connector is fixedly installed at the bottom of the annular limiting seat.

[0011] In some embodiments, the flow-through connector is connected to the corresponding flow-through connection pipe through a gas guiding hose. The flow-through connection pipe is communicated with the annular installation cavity, and the flow-through connection pipe is located outside the annular elastic ring; an inclined surface diversion ring coaxial with the annular limiting seat is fixedly arranged at the top of the annular limiting seat. A liquid collecting cover coaxial with the annular limiting seat is fixedly arranged on the peripheral side of the annular limiting seat. A liquid collecting cavity is arranged inside the liquid collecting cover. A control valve communicating with the liquid collecting cavity is installed at the bottom of the liquid collecting cover. Liquid guiding holes communicating with the liquid collecting cavity are formed on the inner wall of the liquid collecting cover.

[0012] In some embodiments, the present invention further includes a barrel support assembly; wherein, the barrel support assembly includes a barrel support seat, a barrel placement groove for supporting the hazardous waste barrel is formed at the top of the barrel support seat, limiting grooves corresponding to the limiting members one by one are formed on the inner wall of the barrel placement groove, and the circumferential side surface of the guiding member is slidably attached to the inner wall of the hollow ring seat; the outer wall of the hollow ring seat is closely fitted to the inner wall of the barrel placement groove, the limiting member is in clearance fit inside the corresponding limiting groove, an air guiding cavity is arranged inside the barrel support seat, an outer joint communicated with the air guiding cavity is installed at the top of the barrel support seat, a first ventilation hole communicated with the air guiding cavity is formed on the inner wall of the barrel placement groove, a second ventilation hole communicated with its inner cavity is formed on the outer wall of the hollow ring seat, and the positions of the first ventilation hole and the second ventilation hole are adapted to each other.

[0013] The present invention has the following beneficial effects: 1. After the hazardous waste barrel is placed in the barrel placement groove and the position of the hazardous waste barrel is limited by each barrel positioning part and the leak-proof assembly, air is conveyed into the annular installation cavity to gradually expand the annular elastic ring so that it closely adheres to the outer surface of the hazardous waste barrel. At this time, the control valves on each flow-through connecting pipe are closed. During transportation, the spilled hazardous waste liquid cannot flow down along the contact gap between the annular limiting seat and the hazardous waste barrel due to the blocking effect of the annular elastic ring, and can only be gathered between the inclined surface diversion ring and the liquid collecting cover. The gathered hazardous waste liquid flows into the liquid collecting cavity along each liquid guiding hole for collection, thereby avoiding the pollution of the entire tray and the transportation carriage by the hazardous waste liquid during transportation.

[0014] 2. By rotating the rotation linkage ring forward, the circumferential movement of each linkage port on the rotation linkage assembly occurs. During this process, each toggle rod is pushed to slide along the corresponding guiding channel through the linkage port, and the support shaft rotating synchronously with the first positioning member drives the second positioning member to rotate in a direction deviating from the axis. After rotating each barrel positioning part in a direction deviating from the axis by a certain angle, the hazardous waste barrel is placed between the circumferentially arranged barrel positioning parts. Subsequently, the rotation linkage ring is rotated in the reverse direction to complete its reset. Under the action of the torsion springs at the positions of each barrel positioning part, the circumferentially arranged barrel positioning parts tightly press against the circumferential side surface of the hazardous waste barrel under the action of strong elastic force, that is, each circumferentially arranged first positioning member at the lower layer tightly presses against the circumferential side surface of the hazardous waste barrel, and at the same time, each circumferentially arranged second positioning member at the upper layer tightly presses against the circumferential side surface of the hazardous waste barrel. In this way, the position of the hazardous waste barrel can be limited, and the limiting effect on the hazardous waste barrel can be greatly improved.

[0015] 3. After the position of the hazardous waste barrel is defined in the present invention, the annular limiting seat is sleeved and installed on the hazardous waste barrel, and each locking tube is inserted onto the corresponding locking rod, thereby realizing the installation of the leak-proof component on the hazardous waste barrel. Through this installation method, the position of the hazardous waste barrel can be defined again, effectively preventing the positioning parts of each barrel from detaching from the hazardous waste barrel due to shaking or vibration during transportation, and thus greatly improving the stability of the position definition of the hazardous waste barrel. Subsequently, by controlling the gradual expansion of the annular elastic ring to make it closely adhere to the outer surface of the hazardous waste barrel, the installation of the hazardous waste barrel containing hazardous liquid waste on the transportation tray is completed.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0030] For specific embodiment 1, please refer to Figure 1-11The present invention is a hazardous waste transport pallet with a leak-proof function, comprising a barrel body positioning assembly 1, a rotating linkage assembly 2 is installed on the barrel body positioning assembly 1, and a leak-proof assembly 3 coaxial with the rotating linkage assembly 2 is arranged above the rotating linkage assembly 2; wherein the barrel body positioning assembly 1 includes a plurality of barrel body positioning parts 4 arranged in an annular direction and connected by a torsion spring, and the barrel body positioning part 4 is used to press tightly against the outer wall of the hazardous waste barrel 5 to realize the positioning of the hazardous waste barrel 5; the rotating linkage assembly 2 is coaxially arranged with the barrel body positioning assembly 1, and the rotating linkage assembly 2 is used to realize the synchronous rotation of the plurality of barrel body positioning parts 4 arranged in an annular direction, and the rotating linkage assembly 2 is rotated in the forward direction so that each barrel When the body positioning part 4 rotates synchronously in a direction away from the axis, the hazardous waste barrel 5 can be placed between the circumferentially arranged barrel body positioning parts 4, and then the rotary linkage assembly 2 is rotated in the opposite direction to complete its reset. At this time, through the action of the torsion springs at the positions of the barrel body positioning parts 4, the circumferentially arranged barrel body positioning parts 4 are tightly pressed against the side surfaces of the hazardous waste barrel 5 under the action of strong elastic force, so that the position of the hazardous waste barrel 5 can be limited; the leak-proof assembly 3 includes a locking part 6 and a leak-proof part 7. The locking part 6 is arranged one-to-one with the barrel body positioning part 4 and the two are plugged in and matched. The leak-proof part 7 is mounted on the hazardous waste barrel 5 and is used to collect leaked hazardous waste liquid.

[0031] In some embodiments, as Figure 7 As shown, the barrel body positioning assembly 1 also includes a hollow ring seat 101, and a plurality of limit members 102 are fixedly arranged on the side surface of the hollow ring seat 101. An annular reinforcement plate 103 coaxial with the hollow ring seat is arranged above the hollow ring seat 101, and a plurality of flow joints 104 connected with the inner cavity thereof are installed on the top of the hollow ring seat 101. The annular reinforcement plate 103 connects each barrel body positioning part 4 so that the annular reinforcement plate 103 and each barrel body positioning part 4 thereon form an integrated structure, thereby improving the stability of each barrel body positioning part 4 during use.

[0032] The barrel body positioning part 4 includes a support shaft 105 connected to the inner side of the hollow ring seat 101 through a torsion spring, and the annular reinforcement plate 103 is rotatably connected to each support shaft 105. The first positioning member 106 and the second positioning member 107 are fixedly installed on the side surface of the support shaft 105. The first positioning member 106 is located below the annular reinforcement plate 103, and the second positioning member 107 is located above the annular reinforcement plate 103. A guide groove 108 is provided on the top of the first positioning member 106, and a toggle rod 109 is slidingly provided inside the guide groove 108. An elastic element connected to the corresponding toggle rod 109 is provided inside the guide groove 108 (to ensure that the toggle rod 109 can be automatically reset after moving), and a locking rod 110 is fixed on the top of the second positioning member 107.

[0033] In some embodiments, as Figure 8 and Figure 9As shown in the figure, the rotation linkage assembly 2 includes a rotation linkage ring 201. A number of linkage ports 202 are circumferentially arranged at the top of the rotation linkage ring 201. The linkage ports 202 are arranged in one-to-one correspondence with the toggle rods 109. The toggle rods 109 are penetrated and fitted inside the corresponding linkage ports 202. A guide member 203 corresponding to the barrel positioning portion 4 is fixedly arranged on the circumferential side surface of the rotation linkage ring 201.

[0034] The locking portion 6 includes a vertically arranged support rod 301. A locking tube 302 is fixedly arranged at the bottom of the support rod 301. The locking tube 302 is inserted and fitted with the locking rod 110 below it. By rotating the rotation linkage ring 201 in the positive direction, the circumferential movement of each linkage port 202 on the rotation linkage assembly 2 occurs. During this process, each toggle rod 109 is pushed to slide along the corresponding guide channel 108 through the linkage port 202. During the sliding process of each toggle rod 109, the corresponding elastic element is squeezed. As a result, the first positioning members 106 on each barrel positioning portion 4 are synchronously rotated in a direction deviating from the axis. The support shaft 105 that rotates synchronously with the first positioning member 106 drives the second positioning member 107 to rotate in a direction deviating from the axis (that is, the first positioning member 106 and the second positioning member 107 always rotate synchronously). After rotating each barrel positioning portion 4 in a direction deviating from the axis by a certain angle, the hazardous waste barrel 5 is placed between the circumferentially arranged barrel positioning portions 4. Subsequently, the rotation linkage ring 201 is rotated in the reverse direction to complete its reset. During this process, under the action of the elastic restoring force of the elastic elements in each guide channel 108, each toggle rod 109 slides reversely along the corresponding guide channel 108. At the same time, under the action of the torsion springs at the positions of each barrel positioning portion 4, the circumferentially arranged barrel positioning portions 4 are tightly pressed against the circumferential side surface of the hazardous waste barrel 5 under the action of strong elastic force. That is, the circumferentially arranged first positioning members 106 in the lower layer are tightly pressed against the circumferential side surface of the hazardous waste barrel 5, and at the same time, the circumferentially arranged second positioning members 107 in the upper layer are tightly pressed against the circumferential side surface of the hazardous waste barrel 5. In this way, the position limitation of the hazardous waste barrel 5 can be realized, and the limiting effect on the hazardous waste barrel 5 can be greatly improved.

[0035] Specific Embodiment 2, on the basis of Specific Embodiment 1, as Figure 9 、 Figure 10 and Figure 11As shown, the leak-proof part 7 includes an annular limiting seat 303 which is used to be sleeved on the hazardous waste barrel 5. An annular installation cavity 304 is formed in the inner wall of the annular limiting seat 303, and an annular elastic ring 305 (made of wear-resistant elastic material) is installed inside the annular installation cavity 304. A flow-through connecting pipe 306 corresponding to the flow-through joint 104 is fixedly installed at the bottom of the annular limiting seat 303. Through the above structural design, when continuously delivering an air flow into the annular installation cavity 304 through the flow-through connecting pipe 306, the air pressure in the annular installation cavity 304 gradually increases, and then the annular elastic ring 305 gradually expands and closely adheres to the outer surface of the hazardous waste barrel 5. In this way, it can effectively prevent the spilled hazardous waste liquid from flowing downward along the contact gap between the annular limiting seat 303 and the hazardous waste barrel 5, thereby avoiding the pollution of the entire tray and the transport carriage by the hazardous waste liquid during transportation.

[0036] In some embodiments, as Figure 1 、 Figure 9 and Figure 11 shown, the flow-through joint 104 and the corresponding flow-through connecting pipe 306 are connected by a gas guide hose. The flow-through connecting pipe 306 is communicated with the annular installation cavity 304, and the flow-through connecting pipe 306 is located outside the annular elastic ring 305 (a control valve is installed on each flow-through connecting pipe 306); a beveled flow guide ring 307 coaxial with it is fixedly arranged at the top of the annular limiting seat 303, and a liquid collecting cover 308 coaxial with it is fixedly arranged on the circumferential side of the annular limiting seat 303. A liquid collecting cavity 309 is arranged inside the liquid collecting cover 308. A control valve communicated with the liquid collecting cavity 309 is installed at the bottom of the liquid collecting cover 308. Liquid guide holes 310 communicated with the liquid collecting cavity 309 are formed in the inner wall of the liquid collecting cover 308; after the position of the hazardous waste barrel 5 is limited, the annular limiting seat 303 is sleeved and installed on the hazardous waste barrel 5, and each locking pipe 302 is inserted into the corresponding locking rod 110, thereby realizing the installation of the leak-proof component 3 on the hazardous waste barrel 5. Through this installation method, the position of the hazardous waste barrel 5 can be limited again, and it can effectively prevent each barrel positioning part 4 from separating from the hazardous waste barrel 5 due to shaking or vibration during transportation, and then can greatly improve the stability of the position limitation of the hazardous waste barrel 5. Subsequently, by controlling the annular elastic ring 305 to gradually expand and closely adhere to the outer surface of the hazardous waste barrel 5, the installation of the hazardous waste barrel 5 containing hazardous waste liquid on the transport tray is completed.

[0037] In some embodiments, as Figure 6As shown in the figure, the present invention further includes a barrel supporting component 8; wherein, the barrel supporting component 8 includes a barrel supporting seat 801, a barrel placing groove 802 for supporting the hazardous waste barrel 5 is formed at the top of the barrel supporting seat 801, and limiting grooves 803 corresponding to the limiting members 102 one by one are formed on the inner wall of the barrel placing groove 802. The circumferential side surface of the guiding member 203 is slidably attached to the inner wall of the hollow ring seat 101 (to ensure the smoothness of the rotation of the rotation linkage assembly 2); the outer wall of the hollow ring seat 101 is tightly fitted to the inner wall of the barrel placing groove 802, and the limiting member 102 is in clearance fit inside the corresponding limiting groove 803 (thus realizing the position limitation of the hollow ring seat 101 in the barrel placing groove 802). A gas guiding cavity is arranged inside the barrel supporting seat 801, and an external joint 804 communicated with the gas guiding cavity is installed at the top of the barrel supporting seat 801 (this external joint 804 can be externally connected to the connecting pipe of the gas supply device). The first ventilation holes communicated with the gas guiding cavity are formed on the inner wall of the barrel placing groove 802, and the second ventilation holes communicated with its inner cavity are formed on the outer wall of the hollow ring seat 101, and the positions of the first ventilation holes and the second ventilation holes are adapted to each other.

[0038] After placing the hazardous waste barrel 5 into the barrel placing groove 802 and realizing the position limitation of the hazardous waste barrel 5 through each barrel positioning part 4 and the leak-proof component 3, air is conveyed into the gas guiding cavity through the gas supply device and the external joint 804. The air entering the gas guiding cavity flows into the inner cavity of the hollow ring seat 101 along the first ventilation holes and the second ventilation holes, and then enters the annular installation cavity 304 through the flow connection joint 104, the gas guiding hose and the flow connection pipe 306, so that the air pressure in the annular installation cavity 304 is gradually increased, and then the annular elastic ring 305 is gradually expanded and tightly attached to the outer surface of the hazardous waste barrel 5. Subsequently, the control valves on each flow connection pipe 306 are closed, and the connecting pipe on the gas supply device is detached from the external joint 804. In the same way, the installation of most hazardous waste barrels 5 on each transport tray can be realized. After the hazardous waste liquid overflows due to shaking or vibration during transportation, the overflowed hazardous waste liquid cannot flow down along the contact gap between the annular limiting seat 303 and the hazardous waste barrel 5 due to the blocking effect of the annular elastic ring 305. The overflowed hazardous waste liquid can only be gathered between the inclined surface diversion ring 307 and the liquid collecting cover 308, and the gathered hazardous waste liquid flows into the liquid collecting cavity 309 along each liquid guiding hole 310 for collection, thereby avoiding the pollution of the entire tray and the transport carriage by the hazardous waste liquid during transportation. After transporting the hazardous waste barrel 5 to the destination, the hazardous waste barrel 5 is taken off the transport tray, and then the control valve at the bottom of the liquid collecting cover 308 is opened to discharge the hazardous waste liquid in the liquid collecting cavity 309.
