A hazardous waste drum transport pallet with leak-proof function

Abstract

The application discloses a dangerous waste transportation tray with a leakage prevention function, and relates to the technical field of transportation trays. A rotating linkage assembly is installed on a barrel positioning assembly, and a leakage prevention assembly coaxial with the rotating linkage assembly is arranged above the rotating linkage assembly. The barrel positioning assembly comprises a plurality of barrel positioning parts arranged in a ring shape and connected by torsional springs. The barrel positioning parts are used for tightly pressing against the outer wall of a dangerous waste barrel to position the dangerous waste barrel. The rotating linkage assembly is used for synchronously rotating the barrel positioning parts arranged in a ring shape. A leakage prevention part is installed on the dangerous waste barrel in a sleeved manner and is used for collecting leaked dangerous waste liquid. After the position of the dangerous waste barrel is limited, the expansion of the annular elastic ring tightly adheres to the outer surface of the dangerous waste barrel. During transportation, the dangerous waste liquid overflowing from the dangerous waste barrel cannot flow downward along the contact gap between the annular limiting seat and the dangerous waste barrel due to the blocking effect of the annular elastic ring, thereby avoiding the pollution of the entire tray and the transportation compartment by the dangerous waste liquid during transportation.

Description

Technical Field

[0001] This invention belongs to the field of transport pallet technology, and in particular relates to a hazardous waste barrel transport pallet with leak-proof function. Background Technology

[0002] With industrial development, the amount of hazardous waste liquid discharged from industrial production processes is increasing. Direct discharge of hazardous waste liquid into the environment can easily cause environmental pollution. In order to reduce the pollution of hazardous waste liquid to the environment, it is necessary to carry out harmless treatment of hazardous waste liquid generated in industrial production processes.

[0003] In existing technologies, the harmless treatment of hazardous waste liquids usually requires loading the hazardous waste liquid into a storage tank, and then transporting the storage tank to a hazardous waste treatment station for harmless treatment. Transport pallets are required during the transportation of the storage tank.

[0004] Existing transport pallets are generally designed for use with forklifts. By directly placing storage containers of hazardous waste liquid onto the pallet, during transport, shaking or vibration can easily cause the hazardous waste liquid to spill from the sealed lid. This spillage contaminates not only the pallet but also the transport vehicle, compromising the safe transport of the hazardous waste liquid. Therefore, we provide a leak-proof hazardous waste container transport pallet to solve the aforementioned problems. Summary of the Invention

[0008] In some embodiments, the barrel positioning part includes a support shaft connected to the inner side of the hollow ring seat by a torsion spring. The annular reinforcing plate is rotatably connected to each support shaft. A first positioning member and a second positioning member are 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 guide groove is provided on the top of the first positioning member, and a toggle rod is slidably arranged inside the guide groove. A locking rod is fixedly arranged on the top of the second positioning member.

[0009] In some embodiments, the rotary linkage assembly includes a rotary linkage ring, the top of which is circumferentially arranged with a plurality of linkage ports, each linkage port corresponding to a lever, the lever penetrating and engaging within the corresponding linkage port, the guide channel containing an elastic element connected to the corresponding lever, and the circumferential side of the rotary linkage ring being fixedly provided with guide members corresponding to the barrel positioning part.

[0010] In some embodiments, the locking part includes a vertically arranged support rod, and a locking tube is fixedly provided at the bottom of the support rod, the locking tube being inserted and engaged with the locking rod below it; the leak-proof part includes an annular limiting seat, the annular limiting seat being used to fit onto the hazardous waste bin, the annular limiting seat having an annular mounting cavity on its inner wall, an annular elastic ring being installed inside the annular mounting cavity, and a flow pipe corresponding to the flow connector being fixedly installed at the bottom of the annular limiting seat.

[0011] In some embodiments, the flow connector and the corresponding flow pipe are connected by a gas guide hose, the flow pipe is connected to the annular mounting cavity, and the flow pipe is located outside the annular elastic ring; the top of the annular limiting seat is fixedly provided with a sloping flow guide ring coaxial with it, the periphery of the annular limiting seat is fixedly provided with a liquid collection hood coaxial with it, the liquid collection hood is provided with a liquid collection chamber inside, the bottom of the liquid collection hood is installed with a control valve connected to the liquid collection chamber, and the inner wall of the liquid collection hood is provided with a liquid guide hole connected to the liquid collection chamber.

[0012] In some embodiments, the present invention further includes a barrel support assembly; wherein the barrel support assembly includes a barrel support seat, the top of the barrel support seat is provided with a barrel placement groove for supporting hazardous waste barrels, the inner wall of the barrel placement groove is provided with limiting grooves corresponding to limiting members, the peripheral side of the guide member is slidably attached to the inner wall of the hollow ring seat; the outer wall of the hollow ring seat is tightly fitted to the inner wall of the barrel placement groove, the limiting members are loosely fitted inside the corresponding limiting grooves, the barrel support seat is provided with an air guiding cavity, the top of the barrel support seat is installed with an external connector communicating with the air guiding cavity, the inner wall of the barrel placement groove is provided with a first vent hole communicating with the air guiding cavity, the outer wall of the hollow ring seat is provided with a second vent hole communicating with its inner cavity, and the positions of the first vent hole and the second vent hole are adapted to each other.

[0013] The present invention has the following beneficial effects: 1. After the hazardous waste bin is placed in the bin placement slot and the position of the hazardous waste bin is limited by each bin positioning part and the anti-leakage component, air is supplied to the annular mounting cavity to cause the annular elastic ring to gradually expand and stick tightly to the outer surface of the hazardous waste bin. At this time, the control valves on each flow pipe are closed. During transportation, the hazardous waste liquid that overflows cannot flow down along the contact gap between the annular limiting seat and the hazardous waste bin due to the obstruction of the annular elastic ring. It can only be collected between the inclined guide ring and the liquid collection hood. The collected hazardous waste liquid flows into the liquid collection cavity along each liquid guide hole to achieve collection, thereby avoiding the pollution of the entire pallet and transport vehicle by the hazardous waste liquid during transportation.

[0014] 2. This invention uses a forward-rotating linkage ring to cause circumferential movement of each linkage port on the rotating linkage assembly. During this process, the linkage ports push each actuating rod to slide along the corresponding guide groove. The support shaft, which rotates synchronously with the first positioning component, drives the second positioning component to rotate off-axis. After rotating each barrel positioning part off-axis by a certain angle, the hazardous waste barrel is placed between the circumferentially arranged barrel positioning parts. Then, the rotating linkage ring is rotated in the reverse direction to reset it. Through the action of the torsion spring at the position of each barrel positioning part, the circumferentially arranged barrel positioning parts are pressed tightly against the periphery of the hazardous waste barrel under strong elastic force. That is, the lower circumferentially arranged first positioning parts are pressed tightly against the periphery of the hazardous waste barrel, and the upper circumferentially arranged second positioning parts are pressed tightly against the periphery of the hazardous waste barrel. In this way, the position of the hazardous waste barrel can be limited, which can greatly improve the limiting effect of the hazardous waste barrel.

[0015] 3. After defining the position of the hazardous waste bin, the present invention installs an annular limiting seat onto the hazardous waste bin and inserts each locking tube into the corresponding locking rod, thereby achieving the installation of the leak-proof component on the hazardous waste bin. This installation method can further define the position of the hazardous waste bin, effectively preventing the positioning parts of the bin from detaching from the hazardous waste bin due to shaking or vibration during transportation, thus greatly improving the stability of the position definition of the hazardous waste bin. Subsequently, by controlling the gradual expansion of the annular elastic ring to make it tightly adhere to the outer surface of the hazardous waste bin, the installation of the hazardous waste bin containing hazardous waste liquid on the transport pallet is completed.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] For a specific implementation example, please refer to Implementation Example 1. Figure 1-11This invention relates to a leak-proof hazardous waste container transport pallet, comprising a container positioning assembly 1, a rotation linkage assembly 2 mounted on the container positioning assembly 1, and a leak-proof assembly 3 coaxially positioned above the rotation linkage assembly 2. The container positioning assembly 1 includes a plurality of circumferentially arranged container positioning parts 4 connected by torsion springs, which are used to press tightly against the outer wall of the hazardous waste container 5 to achieve positioning of the container 5. The rotation linkage assembly 2 is coaxially arranged with the container positioning assembly 1, and the rotation linkage assembly 2 is used to achieve synchronous rotation of the circumferentially arranged container positioning parts 4. Rotating the rotation linkage assembly 2 in the forward direction causes each container to rotate synchronously. When the body positioning part 4 rotates synchronously in a direction away from the axis, the hazardous waste bin 5 can be placed between the various bin positioning parts 4 arranged in a ring. Then, by rotating the linkage component 2 in the opposite direction, it can be reset. At this time, through the action of the torsion spring at the position of each bin positioning part 4, the various bin positioning parts 4 arranged in a ring are pressed tightly against the side of the hazardous waste bin 5 under the action of strong elasticity, thus realizing the position limitation of the hazardous waste bin 5. The leak-proof component 3 includes a locking part 6 and a leak-proof part 7. The locking part 6 is set one-to-one with the bin positioning part 4 and the two are inserted and matched. The leak-proof part 7 is sleeved on the hazardous waste bin 5 and is used to collect the leaked hazardous waste liquid.

[0031] In some implementation schemes, such as Figure 7 As shown, the barrel positioning assembly 1 also includes a hollow ring seat 101. Several limiting members 102 are fixedly arranged on the periphery of the hollow ring seat 101. An annular reinforcing plate 103 coaxial with the hollow ring seat 101 is arranged above the hollow ring seat 101. Several flow connectors 104 communicating with the inner cavity are installed on the top of the hollow ring seat 101. Through the connection of the annular reinforcing plate 103 to each barrel positioning part 4, the annular reinforcing plate 103 and each barrel positioning part 4 on it form an integrated structure, thereby improving the stability of each barrel positioning part 4 during use.

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

[0033] In some implementation schemes, such as Figure 8 and Figure 9As shown, the rotary linkage assembly 2 includes a rotary linkage ring 201. The top of the rotary linkage ring 201 is circumferentially arranged with a plurality of linkage ports 202. The linkage ports 202 are correspondingly set with the levers 109. The levers 109 pass through and are fitted inside the corresponding linkage ports 202. The circumferential side of the rotary linkage ring 201 is fixedly provided with guide members 203 corresponding to the barrel positioning part 4.

[0034] The locking part 6 includes a vertically arranged support rod 301, and a locking tube 302 is fixedly installed at the bottom of the support rod 301. The locking tube 302 is inserted and engaged with the locking rod 110 below it. By rotating the rotating linkage ring 201 in the forward direction, the linkage ports 202 on the rotating linkage assembly 2 will move in a circumferential direction. During this process, the linkage ports 202 push the actuating rods 109 to slide along the corresponding guide channels 108. During the sliding process of each actuating rod 109, it squeezes the corresponding elastic element, thereby causing the first positioning member 106 on each barrel positioning part 4 to rotate synchronously in a direction away from the axis. The support shaft 105, which rotates synchronously with the first positioning member 106, drives the second positioning member 107 to rotate in a direction away from the axis (that is, the first positioning member 106 and the second positioning member 107 always rotate synchronously). This causes the barrel positioning parts 4 to rotate in a direction away from the axis. After rotating a certain angle in the axial direction, the hazardous waste bin 5 is placed between the circumferentially arranged bin positioning parts 4. Then, the rotating linkage ring 201 is rotated in the opposite direction to reset it. During this process, the elastic restoring force of the elastic element in each guide channel 108 causes each actuating rod 109 to slide in the opposite direction along the corresponding guide channel 108. At the same time, the torsion spring at the position of each bin positioning part 4 causes the circumferentially arranged bin positioning parts 4 to press tightly against the circumferential side of the hazardous waste bin 5 under the action of strong elastic force. That is, the lower circumferentially arranged first positioning parts 106 press tightly against the circumferential side of the hazardous waste bin 5, while the upper circumferentially arranged second positioning parts 107 press tightly against the circumferential side of the hazardous waste bin 5. In this way, the position of the hazardous waste bin 5 can be limited, which can greatly improve the limiting effect of the hazardous waste bin 5.

[0035] Specific embodiment two, based on specific embodiment one, such as Figure 9 , Figure 10 and Figure 11As shown, the leak-proof part 7 includes an annular limiting seat 303, which is used to fit onto the hazardous waste container 5. An annular mounting cavity 304 is formed on the inner wall of the annular limiting seat 303. An annular elastic ring 305 (wear-resistant elastic material) is installed inside the annular mounting cavity 304. A flow pipe 306 corresponding to the flow connector 104 is fixedly installed at the bottom of the annular limiting seat 303. Through the above structural design, when air is continuously supplied into the annular mounting cavity 304 through the flow pipe 306, the air pressure in the annular mounting cavity 304 gradually increases, causing the annular elastic ring 305 to gradually expand and tightly adhere to the outer surface of the hazardous waste container 5. This effectively prevents the overflowing hazardous waste liquid from flowing down along the contact gap between the annular limiting seat 303 and the hazardous waste container 5, thereby preventing the hazardous waste liquid from contaminating the entire pallet and transport vehicle during transportation.

[0036] In some implementation schemes, such as Figure 1 , Figure 9 and Figure 11 As shown, the flow connector 104 is connected to the corresponding flow pipe 306 via a venting hose. The flow pipe 306 is connected to the annular mounting cavity 304 and is located outside the annular elastic ring 305 (a control valve is installed on each flow pipe 306). A sloping flow guide ring 307 coaxially mounted on the top of the annular limiting seat 303 is fixedly mounted. A liquid collecting hood 308 coaxially mounted on the periphery of the annular limiting seat 303 is fixedly mounted. A liquid collecting chamber 309 is provided inside the liquid collecting hood 308. A control valve connected to the liquid collecting chamber 309 is installed at the bottom of the liquid collecting hood 308. A liquid guiding hole 31 communicating with the liquid collecting chamber 309 is opened on the inner wall of the liquid collecting hood 308. 0; After the position of the hazardous waste bin 5 is defined, the annular limiting seat 303 is fitted onto the hazardous waste bin 5, and each locking tube 302 is inserted into the corresponding locking rod 110. This achieves the installation of the leak-proof component 3 on the hazardous waste bin 5. This installation method can again define the position of the hazardous waste bin 5, effectively preventing the positioning parts 4 of each bin from falling off the hazardous waste bin 5 due to shaking or vibration during transportation. This greatly improves the stability of the position definition of the hazardous waste bin 5. Then, by controlling the annular elastic ring 305 to gradually expand and make it stick tightly to the outer surface of the hazardous waste bin 5, the installation of the hazardous waste bin 5 containing hazardous waste liquid on the transport pallet is completed.

[0037] In some implementation schemes, such as Figure 6As shown, the present invention also includes a barrel support assembly 8; wherein, the barrel support assembly 8 includes a barrel support seat 801, the top of the barrel support seat 801 is provided with a barrel placement groove 802 for supporting the hazardous waste barrel 5, the inner wall of the barrel placement groove 802 is provided with a limiting groove 803 corresponding to the limiting member 102, the peripheral side of the guide member 203 is slidably attached to the inner wall of the hollow ring seat 101 (to ensure the stability of the rotation process 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 placement groove 802, and the limiting member 102... The clearance fit is inside the corresponding limiting groove 803 (thus limiting the position of the hollow ring seat 101 in the barrel placement groove 802). The barrel support 801 is provided with an air guiding cavity. The top of the barrel support 801 is equipped with an external connector 804 that communicates with the air guiding cavity (the external connector 804 can be connected to the connecting pipe of the air supply equipment). The inner wall of the barrel placement groove 802 is provided with a first vent hole that communicates with the air guiding cavity. The outer wall of the hollow ring seat 101 is provided with a second vent hole that communicates with its inner cavity. The positions of the first vent hole and the second vent hole are matched.

[0038] After placing the hazardous waste bin 5 into the bin placement slot 802 and defining its position using the bin positioning parts 4 and leak-proof components 3, air is supplied to the air guide chamber via the air supply equipment and external connector 804. The air entering the air guide chamber flows into the inner cavity of the hollow ring seat 101 through the first and second vent holes, and then enters the annular mounting cavity 304 through the flow connector 104, air guide hose, and flow pipe 306. This gradually increases the air pressure in the annular mounting cavity 304, causing the annular elastic ring 305 to gradually expand and press tightly against the outer surface of the hazardous waste bin 5. Then, the control valves on each flow pipe 306 are closed, and the connecting pipes on the air supply equipment are disconnected from the external connector 804. The same process can then be repeated. Most of the hazardous waste containers 5 are installed on various transport pallets. During transportation, if hazardous waste liquid overflows due to shaking or vibration, the overflowing hazardous waste liquid cannot flow down along the contact gap between the annular limit seat 303 and the hazardous waste container 5 due to the obstruction of the annular elastic ring 305. The overflowing hazardous waste liquid can only be collected between the inclined guide ring 307 and the liquid collection hood 308. The collected hazardous waste liquid flows into the liquid collection chamber 309 through each liquid guide hole 310 for collection, thereby avoiding the pollution of the entire pallet and transport vehicle by hazardous waste liquid during transportation. After the hazardous waste container 5 is transported to the destination, the hazardous waste container 5 is removed from the transport pallet, and the control valve at the bottom of the liquid collection hood 308 is opened to discharge the hazardous waste liquid in the liquid collection chamber 309.
