Description
Technical Field
[0001] This utility model relates to the field of gas tank unloading technology, and more specifically, it relates to an unloading device. Background Technology
[0002] Combustible gases such as natural gas or hydrogen generally require storage and transportation in gas cylinders. For long-distance transportation, trucks are used, and unloading devices are needed to safely remove the gas cylinders from the trucks. Existing unloading devices can only provide simple guidance for the gas cylinders. The gas cylinders fall quickly during unloading, making them prone to collisions and damage. There is a lack of suitable safety support mechanisms during the unloading process. Furthermore, when using safety support mechanisms, the limit mechanisms are not convenient to adjust when protecting different types of gas cylinders during unloading, and their practicality needs to be improved. In addition, after unloading, the gas cylinders are placed on a transfer rack for transportation. The stability of the transfer rack is poor, and there is a lack of suitable quick-connect and disconnection mechanisms between the transfer rack and the unloading device. Utility Model Content

[0030] More specifically, the position of the limiting plate 10 is adjusted according to the model of the gas tank to be unloaded. The limiting plate 10 and the support plate 5 cooperate to support and limit the gas tank. The transfer frame 11 is installed corresponding to the unloading plate 1 to collect the unloaded gas tank. After collection, the transfer frame 11 and the unloading plate 1 are separated, and the caster wheel 12 drives the transfer frame 11 to move.
[0031] Please see Figure 1 and Figure 3 As one embodiment of the limiting plate 10: both limiting plates 10 are provided with T-shaped plates 13, and the support plate 5 is provided with guide grooves 14 corresponding to the two T-shaped plates 13. The guide grooves 14 are provided with guide rods 15 corresponding to the two T-shaped plates 13. Both T-shaped plates 13 are symmetrically provided with locking holes 16. Each locking hole 16 is provided with a locking rod 17. The locking rod 17 and the locking hole 16 are threadedly connected. The lower end face of the support plate 5 is provided with locking grooves 18 on both the upper and lower sides corresponding to the multiple locking rods 17.
[0032] Specifically, the T-shaped plate 13 slides and guides relative to the guide groove 14 with the guide rod 15. After sliding and adjusting to a suitable position, the locking rod 17 is rotated. The locking rod 17 and the locking hole 16 are threaded together. The locking rod 17 is inserted into the locking groove 18 to strengthen the locking and achieve the locking of the position of the limiting plate 10.
[0033] Please see Figure 2 and Figure 4 As one embodiment of disassembling and assembling the transfer frame 11: the rear end of the transfer frame 11 is symmetrically provided with mounting blocks 19, the front end of the unloading plate 1 is provided with mounting grooves 20 corresponding to the two mounting blocks 19, the left and right ends of the unloading plate 1 are provided with mounting rods 21, the two mounting blocks 19 are provided with mounting holes 22 corresponding to the mounting rods 21, the outer ends of the two mounting rods 21 are provided with mounting rings 23, and springs 24 are connected between the mounting rings 23 and the unloading plate 1, and the springs 24 are fitted on the outer ends of the mounting rods 21.
[0034] Specifically, when the transfer frame 11 is installed relative to the unloading plate 1, the mounting ring 23 is grasped, the mounting rod 21 is pulled outward, the spring 24 is stretched, the mounting block 19 and the mounting groove 20 cooperate to install and position, the mounting ring 23 is released, the spring 24 retracts, the mounting rod 21 is reset and inserted into the mounting hole 22 of the mounting block 19, and the installation is tightened.
[0035] Please see Figure 1 , Figure 4 and Figure 5 As one embodiment of protection for the transfer frame 11: the upper end face of the transfer frame 11 is provided with a U-shaped guardrail 25, and the left and right sides of the rear end face of the U-shaped guardrail 25 are provided with rotating grooves 26. The two rotating grooves 26 are each provided with a guard plate 27, and the two guard plates 27 are each provided with a first locking hole 28. The two first locking holes 28 are each provided with a locking rod 29, and the locking rod 29 is threadedly connected to the first locking hole 28. The upper end of the transfer frame 11 is provided with a second locking hole 30 corresponding to the two locking rods 29.
[0036] Specifically, the gas cylinder is placed on the transfer frame 11. The U-shaped guardrail 25 and the guard plate 27 work together to protect the internal gas cylinder. When the transfer frame 11 is installed with the unloading plate 1, the guard plate 27 is rotated to the open state. After unloading, the transfer frame 11 and the unloading plate 1 are separated, and the guard plate 27 is rotated to the closed state. The locking rod 29 is rotated, and the locking rod 29 is threaded into the first locking hole 28. The locking rod 29 is inserted downward into the second locking hole 30 of the transfer frame 11 to lock the guard plate 27 in the closed state and to protect the internal gas cylinder.
[0037] In summary, the overall equipment is in use:
[0038] When adjusting the position before unloading, the position of the limiting plate 10 is adjusted according to the model of the gas tank to be unloaded. The T-shaped plates 13 of the two limiting plates 10 slide and guide each other relative to the guide groove 14 with guide rod 15. After sliding and adjusting to the appropriate position, the locking rod 17 is rotated. The locking rod 17 and the locking hole 16 are threaded together, and the locking rod 17 is inserted into the locking groove 18. The position adjustment achieves enhanced locking and facilitates unloading adjustment of different models of gas tanks.
[0039] When the transfer frame 11 is in the disassembly / assembly state, before installation, rotate the locking rod 29. The locking rod 29 engages with the first locking hole 28, and the locking rod 29 is pulled out from the second locking hole 30. The guard plate 27 rotates and opens relative to the rotating groove 26 to a non-conflicting position. The caster wheel 12 drives the transfer frame 11 to the unloading plate 1 position. Grasp the mounting ring 23 and pull the mounting rod 21 outward. The spring 24 is stretched. After the mounting block 19 is installed in the mounting groove 20, release the mounting ring 23, and the spring 24 retracts. The mounting rod 21 is reset and inserted into the mounting hole 22 to secure the installation. After removing an appropriate number of gas cylinders, the transfer frame 11 is disassembled. The mounting rod 21 is pulled outward by gripping the mounting ring 23. The caster wheel 12 drives the transfer frame 11 to move as a whole. After the mounting block 19 is removed from the mounting groove 20, the guard plate 27 is rotated to close. The locking rod 29 is rotated in the opposite direction. The locking rod 29 and the first locking hole 28 are threaded together. The locking rod 29 is inserted downward into the second locking hole 30 to provide safety protection for the gas cylinders placed above the transfer frame 11.
[0040] When unloading, the side of the unloading plate without the adjusting motor 9 is aligned with the external truck. After the limit plate 10 is adjusted, the control device with its own control system starts the adjusting motor 9, which rotates back and forth. The adjusting motor 9 drives the adjusting rod 8 to rotate. The adjusting rod 8 and the slider 6 are threaded together. The slider 6 slides relative to the slide groove 7, which drives the support plate 5 to rise and fall relative to the unloading plate 1. The support plate 5 and the limit plate 10 work together to support and limit the unloaded gas tank, allowing it to be unloaded at a uniform speed, improving unloading safety and preventing the gas tank from falling rapidly and causing damage.
