Description

Technical Field

[0001] The utility model relates to the technical field of dangerous goods unloading, in particular to a parking and loading and unloading platform for a normal pressure tank truck of dangerous goods. Background Art

[0002] At present, the company uses tank trucks to transport hazardous chemicals, and the tank trucks are equipped with storage tanks. In the early stage of unloading hazardous chemicals, the driver reversed based on experience, stopped and unloaded after reaching the appropriate position. When unloading, the unloading port at the rear of the tank truck needs to be connected to the unloading pipe on the transfer tank. The current problem is that the unloading pipe cannot be connected to the unloading port due to frequent parking failures. Therefore, the driver needs to reverse slowly again until the unloading port can be connected to the unloading pipe. This process is also reversed based on experience. There are often cases where the driver makes mistakes when parking, resulting in over-reversing. The distance between the parking position and the feed port of the transfer tank becomes shorter, resulting in the unloading pipe being placed on the ground. The height of the unloading pipe is lower than the height of the feed port of the transfer tank. Therefore, after unloading, there will be hazardous chemicals remaining in the unloading pipe, which will volatilize or scatter on the ground, causing safety hazards. At the same time, since the current loading and unloading platform is a plane, there will also be a problem that the materials in the storage tank on the tank truck cannot be unloaded cleanly. Based on this problem, the existing loading and unloading platform is improved, and a parking and loading and unloading platform for atmospheric pressure tank trucks of hazardous goods is provided. Summary of the invention

[0003] The utility model limits the position of the rear tires of the tank truck by limiting the position of the limit plate or the DN50 steel pipe to further optimize the parking distance, and provides a parking and loading and unloading platform for dangerous goods atmospheric pressure tank trucks, which avoids the situation of under-parking or over-parking and makes the parking process simpler and more convenient.

[0016] The advantages and positive effects of the utility model are:

[0017] When not unloading, the top surface of the limit plate or DN50 steel pipe is flush with the top surface of the downhill area, and does not affect normal driving; when unloading, the limit plate or DN50 steel pipe protrudes from the top surface of the downhill area, and an optimal parking position is provided by the limiting effect of the limit plate or DN50 steel pipe. During reversing, the tank truck stops in place when the rear wheels contact the side of the limit plate or the DN50 steel pipe, thus avoiding the situation of inadequate parking or over-parking, avoiding later adjustments, saving working time, and because it is parked in the designated position, the unloading pipe can be straightened and not fall to the ground. Combined with the fact that the unloading port of the storage tank on the tank truck is higher than the feeding port of the transfer tank, all the materials will enter the transfer tank, reducing the problem of material retention in the unloading pipe and reducing safety hazards.

[0018] The tank truck unloads materials in the downhill area of ​​the platform body. Since the angle between the high point of the platform body and the unloading end and the ground is 30 degrees, the storage tank on the tank truck tends to tilt downward, making it easier to unload the materials in the storage tank. Since the angle is only 30 degrees, the materials in the storage tank can be unloaded and the construction cost of the platform body can be saved.

[0019] The lifting height of the limit plate or DN50 steel pipe is 30-90cm, which can meet the limit requirements of rear tires of different sizes. By limiting the width of the platform body to be greater than 2.5m and less than or equal to 3.2m, the left and right deviation distance of the vehicle is limited and the unloading requirements of tank trucks of different widths can be met.

[0020] The limit plate and the piston rod are fixed by a number of screws, so the structure is more stable, and the stability is further improved by the triangular bracket. Since the top surface of the screw is flush with the top surface of the limit plate after fixation, it does not affect the normal driving of the vehicle.

[0021] The side surface of the limit plate in the parking area is covered with a rubber layer, and at least the upper corner of the two corners covered by the rubber layer is rounded, thereby reducing the friction between the limit plate and the rear tire.

[0022] The distance to the rear tire is measured by the distance sensor within the limit surface. When it reaches the appropriate position, the controller controls the alarm device to warn and remind the driver to stop in time. The unloading status is monitored by the camera to ensure the safety of the work. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present embodiment provides a parking and loading and unloading platform for normal pressure tank trucks of dangerous goods, including a platform body 1, wherein the platform body 1 protrudes from the ground and is built with cement and bricks, such as Figure 1 As shown, the structure from the vehicle entry end to the unloading end is uphill to downhill. The platform body 1 includes an uphill area 2 and a downhill area 3. The high point is between the two areas. Figure 1 As shown by the virtual center and the marked angle, the angle formed by the high point of the platform body 1 to the unloading end and the ground is 30 degrees, and the width of the platform body 1 is 3m. Since the angle is only 30 degrees and the width of the platform body 1 is 3m, it meets the unloading needs of the widest 2.5m tank truck, which not only saves raw materials but also limits the left and right deviation distance of the vehicle, making the parking position more accurate in the later stage.

[0033] like Figure 2 As shown, a groove 4 is provided on the downhill area 3. Figure 3 As shown, two lifting devices are provided in the groove 4, and the lifting devices adopt hydraulic cylinders. The top surface of the lifting devices is provided with a long strip-shaped limit plate 5, and the top end of the piston rod 6 of the hydraulic cylinder is connected to the limit plate 5; the limit plate 5 and the top end of the piston rod 6 are fixed by a plurality of screws, and after fixing, the top surface of the screws is flush with the top surface of the limit plate 5; Figure 4 As shown, the bottom of the limit plate 5 and the outer circumference of the piston rod 6 are further fixed by a plurality of triangular brackets 7, one end of the bracket 7 is against the bottom surface of the limit plate 5, and the other end is against the outer circumference of the piston rod 6, and is fixed by a plurality of screws screwed into the bracket 7 and the threaded holes on the limit plate 5 and the piston rod 6;

[0034] The height of the limit plate 5 is controlled by the lifting device to protrude from the downhill area 3 by 30-90 cm or be flush with the downhill area 3. When the height of the limit plate 5 is flush with the downhill area 3, the limit plate 5 covers the entire top surface of the groove 4. The height of the limit plate 5 protruding from the downhill area 3 by the lifting device is determined according to the size of the tire. In principle, it is higher than the center axis of the rear tire and lower than the top surface of the rear tire.

[0035] A lamp post 9 and a street lamp are provided on the top surface of the downhill area 3 near the downhill area 3; an explosion-proof control box 10 is provided on the lamp post 9, and a signal receiver and a controller are provided in the explosion-proof control box 10, and the lifting state of the lifting device is controlled by the controller; an alarm device is provided on the lamp post 9, and the position signal is received and the alarm device is controlled by the explosion-proof control box 10; a camera is provided on the lamp post 9, and the alarm device is a device on the camera;

[0036] The parking area is between the limit plate 5 and the high point. The side of the limit plate 5 in the parking area is covered with a rubber layer, and the upper corner of the two corners covered by the rubber layer is a rounded corner 8; further, the side of the limit plate 5 covered by the rubber layer is a limit surface, and at least one distance sensor 11 is provided in the limit surface. The distance sensor 11 is used to measure the distance of the rear tire, and the distance sensor 11 is embedded in the limit surface;

[0037] Embodiment 1:

[0038] Step 1: Before unloading, the controller controls the lifting device to further control the height of the limit plate 5 protruding from the downhill area 3, and controls the lifting height of the limit plate 5 according to the size of the tire, so that the limit plate 5 is higher than the center axis of the rear tire and the top surface of the limit plate 5 is lower than the top surface of the rear tire;

[0039] Step 2: According to the width of the platform body 1, adjust the front of the vehicle and the parking space to be in a straight line and align the parking space with the vehicle entry end, and then start reversing;

[0040] Step 3: When the parking space is close to the limit plate 5, the distance sensor 11 sends a signal and controls the alarm device through the controller to sound an alarm to remind the driver to slow down or stop; or directly reverse until the rear tire contacts the rubber layer on the surface of the limit plate 5. Since the side surface of the limit plate 5 in the parking area is covered with a rubber layer, at least the upper corner of the two corners covered by the rubber layer is a rounded corner 8, which can reduce the friction between the limit plate 5 and the rear tire. Due to the limiting effect of the limit plate 5, the tank truck cannot continue to retreat. The limiting function of the limiting plate 5 provides an optimal parking position. During the reversing process, the tank truck stops in place when the rear wheels contact the side of the limiting plate 5, thereby avoiding the situation of under-parking or over-parking, avoiding later adjustments, saving working time, and because it is parked in the designated position, the unloading pipe can be straightened and will not fall to the ground. Combined with the fact that the unloading port of the storage tank on the tank truck is higher than the feeding port of the transfer tank, all the materials will enter the transfer tank, reducing the problem of materials being retained in the unloading pipe and reducing safety hazards.

[0041] Step 4: After the unloading is completed, the top surface of the limit plate 5 is flush with the top surface of the downhill area 3, and does not affect normal driving.

[0042] The street lights need to be turned on during nighttime operation, and the entire unloading process is captured by the camera to avoid safety accidents caused by improper operation.

[0043] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
