Description

Technical Field

[0001] This utility model relates to the field of natural gas transport tank dispatching technology, specifically a liquefied natural gas transport tank dispatching device. Background Technology

[0002] As a clean energy source, liquefied natural gas (LNG) is increasingly in demand in scenarios such as urban gas supply, chemical industrial parks, and emergency peak shaving, creating a rigid demand for short-distance transportation. Although long-distance pipelines are the main transportation method, they lack flexibility in short-distance scenarios such as transfers from receiving stations to distribution centers and tank farms within industrial parks. Short-distance transfer vehicles have become a key connecting hub. Industry policies are driving technological upgrades. The regulations on the safety management of road transport of dangerous goods have strengthened the requirements for tank materials, sealing, and safety devices, promoting the transformation of vehicles towards high safety and lightweight design. Traditional long-distance tank trucks are inefficient when adapted for short-distance, high-frequency transfers due to their large size and inconvenient steering. Specialized models are needed for optimization. At the same time, the application of lightweight materials reduces the overall vehicle weight, and some vehicles integrate simple monitoring systems. With the diversification of short-distance transfer needs, the requirements for vehicle flexibility, loading and unloading efficiency, and compliance are continuously increasing, driving the iteration of structural and safety technologies.

[0003] In existing technologies, short-distance transport vehicles are typically equipped with hydraulic cylinders and fixing belts. The fixing belts are connected to the output end of the hydraulic cylinders, and the fixing belts are tightened by the hydraulic cylinders to fix the tanks to the vehicle body. Although this fixing method has the advantage of convenient operation, during vehicle operation, the inertia generated by the vehicle platform due to starting, stopping, turning, etc., will be directly transmitted to the tanks. Since the fixing belts can only achieve axial tightening, it is difficult to offset the lateral inertial impact force of the tanks, which can easily cause the tanks to slide or shift on the vehicle platform. This not only significantly reduces the stability of tank transportation, but also causes wear on the surface coating of the tanks and even structural damage due to friction and collision between the tanks, the vehicle platform, and the fixing belts, affecting the service life of the tanks and transportation safety. Utility Model Content

[0004] The purpose of this invention is to provide a liquefied natural gas transport tank dispatching device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquefied natural gas transport tank dispatching device, including a vehicle platform, a symmetrically arranged support seat fixedly connected to the top of the vehicle platform, a fixing strap fixedly connected to the back wall of each support seat, a hydraulic cylinder fixedly installed at the middle position of the top of the vehicle platform, a lifting plate fixedly connected to the output end of the hydraulic cylinder, and a symmetrically arranged hook fixedly connected to the top of the lifting plate. The vehicle platform, lifting platform, and support base are all equipped with a positioning mechanism. The positioning mechanism includes symmetrically arranged sliding grooves, first hinge seats, and lifting grooves. Guide rods are fixedly connected inside each sliding groove. Moving blocks are slidably connected to the bottom of each sliding groove. Second hinge seats are fixedly connected to each moving block. A mounting plate is slidably connected to each lifting groove. A third hinge seat is fixedly connected to the bottom of the mounting plate. Positioning blocks are fixedly connected to both ends of the mounting plate. A main rod is hinged to each first hinge seat, and a secondary rod is hinged to each second hinge seat.

[0006] Preferably, one end of each hook is attached to a corresponding fixing strap.

[0007] Preferably, the sliding grooves are symmetrically formed on the vehicle panel, the first hinge seat is symmetrically fixedly connected to the bottom end of the lifting plate, and the lifting grooves are all formed on the side wall of the support seat.

[0008] Preferably, one end of each guide rod slides through the corresponding moving block.

[0009] Preferably, one end of each main rod is hinged to a corresponding second hinge seat, and one end of each secondary rod is hinged to a corresponding third hinge seat.

[0010] Preferably, each of the positioning blocks has a rubber pad fixedly connected inside.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the positioning mechanism is linked with the hydraulic cylinder power source. When the output end of the hydraulic cylinder retracts to drive the fixing belt to tighten, it can simultaneously drive the two positioning blocks in the positioning mechanism to lift upward. After the positioning blocks move upward, they can engage with the two ends of the tank to fit the contour of the tank end, forming a two-way limiting structure. Even if the tank has a tendency to move laterally due to inertia during vehicle start-stop and turning, it will be firmly locked by the two positioning blocks and will not be able to slide relative to each other. This not only greatly improves the overall stability of the tank during short-distance transportation, but also fundamentally avoids friction and collision between the tank and the vehicle board and fixing belt due to lateral movement, effectively protecting the integrity of the tank's external coating and structure, and reducing scratches, wear and other damage.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 The present invention provides the following technical solution: Example 1: A liquefied natural gas transport tank dispatching device includes a vehicle platform 1, a symmetrically arranged support base 2 fixedly connected to the top of the vehicle platform 1, a fixing strap 3 fixedly connected to the back wall of each support base 2, a hydraulic cylinder 4 fixedly installed at the middle position of the top of the vehicle platform 1, a lifting plate 5 fixedly connected to the output end of the hydraulic cylinder 4, and a symmetrically arranged hook 6 fixedly connected to the top of the lifting plate 5, one end of each hook 6 being hooked to the corresponding fixing strap 3; In use, the tank can be hoisted onto the two support seats 2 using an external lifting device. Then, the fixing strap 3 is wrapped around the top of the tank, and one end of the fixing strap 3 is hooked onto the corresponding hook 6. Then, the hydraulic cylinder 4 is activated, causing the output end of the hydraulic cylinder 4 to retract and drive the lifting plate 5 to move down. The movement of the lifting plate 5 will drive the two hooks 6 to move down, and the movement of the hooks 6 will pull on one end of the fixing strap 3, thereby making the fixing strap 3 secure the tank to the two support seats 2. Then, the external power vehicle is connected to one side of the vehicle platform 1 for short-distance transportation.

[0016] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a positioning mechanism 7 is provided on the vehicle plate 1, the lifting plate 5, and the support base 2. The positioning mechanism 7 includes a symmetrically arranged slide groove 71, a first hinge seat 72, and a lifting groove 73. A guide rod 74 is fixedly connected inside the slide groove 71. A moving block 75 is slidably connected to the bottom of the slide groove 71. A second hinge seat 76 is fixedly connected to the moving block 75. The lifting groove 73 is slidably connected to the mounting plate 77. A symmetrically arranged third hinge seat 78 is fixedly connected to the bottom of the mounting plate 77. A positioning block 79 is fixedly connected to both ends of the mounting plate 77. A main rod 80 is hinged to the first hinge seat 72, and a secondary rod 81 is hinged to the second hinge seat 76. The slide grooves 71 are symmetrically opened on the vehicle plate 1. The first hinge seat 72 is symmetrically fixedly connected to the bottom end of the lifting plate 5. The lifting grooves 73 are all opened on the side wall of the support seat 2. One end of the guide rod 74 slides through the corresponding moving block 75. One end of the main rod 80 is hinged to the corresponding second hinge seat 76. One end of the auxiliary rod 81 is hinged to the corresponding third hinge seat 78. The positioning block 79 is fixedly connected with a rubber pad inside. In operation, when the output end of hydraulic cylinder 4 retracts, it causes the lifting plate 5 to move downwards. The downward movement of lifting plate 5 causes both first hinge seats 72 to move downwards together. The downward movement of each first hinge seat 72 causes one end of the main rod 80 to move downwards. At this time, the other end of the main rod 80 acts on the corresponding second hinge seat 76. Driven by one end of the main rod 80, the second hinge seat 76 moves towards the third hinge seat 78. The movement of the second hinge seat 76 causes the moving block 75 to slide inside the slide groove 71. The guide rod 74 guides the movement of the moving block 75 and the second hinge seat 76. The movement of the second hinge seat 76 also causes one end of the auxiliary rod 81 to move. The other end of the auxiliary rod 81 then pushes the third hinge seat 78. Both 78 will move upwards, and the upward movement of the third hinge seat 78 will jointly drive the mounting plate 77 to move upwards. Both ends of the mounting plate 77 will move upwards inside the lifting groove 73. The mounting plate 77 will also drive the two positioning blocks 79 to move upwards. The upward movement of the positioning blocks 79 will respectively wrap around the bottom corners of both sides of the tank. The continuous upward movement of the positioning blocks 79 will cause the internal rubber pads to abut against the tank, so that the two sides of the tank are flexibly positioned by the positioning blocks 79. At this time, the hydraulic cylinder 4 will bind the tank through the fixing strap 3, and the positioning blocks 79 will fix the two ends of the tank, which will close the hydraulic cylinder 4. This not only greatly improves the overall stability of the tank during short-distance transportation, but also fundamentally avoids the friction and collision between the tank and the vehicle plate 1 and the fixing strap 3 due to lateral movement.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
