Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a stacking material anti-dumping device which is used in a carriage and can adapt to articles of various specifications and has a good anti-dumping effect. Background Art

[0002] In the civil explosives industry, packaged cartons, paper bags and other packaging items need to be transported between different sites by transfer vehicles during the production process. In order to reduce the number of people on the production line, a large number of manipulator automatic loading systems have been adopted. The manipulator uses a clamp to stack the packaged items according to certain stacking rules. Because the clamp's movement space requirements cause gaps between the stacked items and between the items and the inner wall of the carriage, and because of the variety of item specifications, a gap of 40 to 50 mm needs to be maintained between the items in the carriage and the anti-dumping device, and there is also a certain relative gap between the stacked items; it is easy to shake during transportation, especially the airbag suspension vehicle currently required by the civil explosives industry. The shaking during the transportation of items is large, and the stacked items are displaced, resulting in the elimination of gaps between some items and the increase of gaps in some items. The items with increased gaps will tilt and tip over, causing damage to the items.

[0003] The existing anti-dumping device has the following problems:

[0004] (1) The existing anti-dumping device can only be adjusted before or after loading, and the gap cannot be adjusted during transportation. The objects move during transportation, causing the gaps between the objects to be concentrated on one side. When the gap increases to a certain extent, the objects will tilt and dump.

[0005] (2) Existing anti-dumping devices are all rigid structures and need to be adjusted according to different specifications. They can only adapt to the situation where the palletizing width is consistent. When a truck needs to load several varieties, it will not be able to play an anti-dumping role when the palletizing width is inconsistent.

[0006] (3) In order to adjust the gap after loading, the existing anti-dumping device can only remove the middle support, resulting in weak structural strength of the anti-dumping device and easy deformation. The deformed position will cause the gap between the cargo and the anti-dumping device to increase. Utility Model Content

[0007] The utility model provides an anti-dumping device for a carriage which has high compatibility, good effect, can adapt to different material specifications, and always ensures the stability of stacked materials.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] The invention discloses an anti-dumping device for a carriage, comprising a plurality of inflatable and deflated air bags, wherein the air bags are fixed on the inner wall of the carriage.

[0010] The design idea of ​​the above technical scheme is that this technical scheme utilizes the flexibility and expandability of the airbag so that the anti-dumping device can adapt to materials of different specifications in the car. No matter how the specifications, volume, and shape of the materials change, the airbag can squeeze the stacked materials and completely fill the gap between the inner wall of the car and the stacked materials, which greatly improves the practicality and anti-dumping effect of the anti-dumping device; at the same time, because the airbag applies force to the stacked materials in the form of a continuous whole, compared with the existing anti-dumping device that has eliminated the intermediate support, its structural strength is higher and it is not easy to deform, which further increases the anti-dumping effect on the stacked materials.

[0011] As a further preferred embodiment of the above technical solution, the plurality of airbags are symmetrically mounted and fixed on the left and right inner walls of the compartment and the door at the rear of the compartment. By arranging an airbag on each side of the inner wall of the automobile compartment and the two rear doors, the airbags can press the cargo from both sides and the rear of the compartment after being inflated, ensuring that the cargo is close to each other and preventing the cargo from falling over.

[0012] As a further preferred embodiment of the above technical solution, an on-board air pump is provided in the vehicle compartment, the airbag is connected to an inflation / exhaust pipe, the inflation / exhaust pipe is provided with a quick inflation / exhaust port and a continuous inflation / exhaust port, the airbag can be connected to an external air pump through the quick inflation / exhaust port for inflation or exhaust, and the airbag is connected to the on-board air pump through the continuous inflation / exhaust port for inflation or exhaust. By setting different inflation / exhaust ports on the inflation / exhaust pipes, the needs under different operating conditions can be met: after parking and loading the cargo or before unloading the cargo, the airbag can be inflated and exhausted through the quick inflation / exhaust port by an external air pump, so as to quickly achieve the expansion and contraction of the airbag and the readiness and withdrawal of the anti-dumping device; during driving, the airbag pressure can be adjusted by inflating through the continuous inflation / exhaust port by the on-board air pump to ensure the stability of the pressure inside the airbag and prevent the airbag from losing pressure due to leakage of the airbag and the connecting pipe, thereby losing the squeezing and holding effect on the cargo; during unloading, in order to ensure that there is a certain gap between the cargo and the car wall for easy unloading, the airbag can be continuously exhausted by the on-board air pump to make the airbag close to the car wall, so as to avoid the anti-dumping device affecting the unloading.

[0013] As a further preferred embodiment of the above technical solution, a hanging lug is provided on the side of the airbag, and a hanging rail is correspondingly provided on the inner wall of the carriage, and the airbag is fixed by the connection between the hanging lug and the hanging rail.

[0014] As a further preferred embodiment of the above technical solution, the airbag is suspended and installed below the inner wall of the compartment, the distance between the bottom of the airbag and the bottom of the compartment is less than the height of the smallest unit that can be separated from the carried items, and the height of the airbag is the same as the stacking height of the carried items. According to the ductility of the airbag, without exceeding the maximum thickness of the airbag, a uniform compression effect can be achieved for goods of different widths, and the inflation pressure can be adjusted according to the rigidity of the goods to avoid excessive squeezing and damage to the goods.

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] The utility model discloses the anti-dumping device for the carriage has strong compatibility and can meet the demand of loading materials of various specifications at the same time. There is no need to change the shape and adjust the material when reinforcing the materials of different specifications. The anti-dumping effect is good and the dumping of the items during transportation can be completely prevented. The airbag is provided with two inflation ports. When quick inflation is required, the airbag can be quickly inflated at the quick inflation port by an external large-capacity inflation pump. The structure is simple and easy to repair and maintain, which can effectively save labor costs and repair and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0024] Embodiment 1:

[0025] The structure of the anti-dumping device for the carriage of this embodiment is as follows: Figure 2 As shown, the arrangement mode in the carriage 1 is as follows Figure 1 As shown, it includes two airbags 2 respectively fixed on the side walls of the carriage 1 and two airbags 2 respectively fixed on the two doors at the rear of the carriage. The structural schematic diagram of the airbag 2 is shown in Figure 3 As shown, the upper and lower ends of the side of the airbag 2 are provided with hanging ears 5, and the airbag is fixed to the inner wall of the carriage 1 through the hanging ears 5. The airbag 2 is suspended and installed below the inner wall of the carriage 1. In actual use, the distance between the bottom of each airbag 2 and the bottom of the carriage 1 should be less than the height of the smallest unit (such as a box, a bag, etc.) of the carried items 6, and the setting height of each airbag 2 should be the same as the stacking height of the carried items 6. The airbag 2 is connected to an inflation / exhaust pipe 4, which is provided with a quick inflation / exhaust port 401 and a continuous inflation / exhaust port 402. Each airbag 2 can be connected to an external air pump through the quick inflation / exhaust port 401 for inflation or exhaust. Each airbag 2 can also be connected to an on-board air pump 3 arranged in the vehicle compartment 1 (or in the driver's cab) through the continuous inflation / exhaust port 402 for inflation or exhaust (the setting structure details of the inflation / exhaust pipe, the quick inflation / exhaust port and the continuous inflation / exhaust port are as shown in the figure). Figure 4 shown).

[0026] Taking a van as an example, the method for using the anti-dumping device for a compartment of this embodiment to reinforce materials against dumping is as follows:

[0027] When the van returns to the loading platform, the on-board air pump 3 is used to evacuate the four air bags 2 through the continuous inflation / exhaust port 402, so that the air bags 2 are in a vacuum state, and the valve of the continuous inflation / exhaust port 402 is closed after a certain vacuum degree is reached, and the on-board air pump 3 is stopped, so that the air bags 2 are closely attached to the inner wall of the carriage 1 to leave enough loading space. After arriving at the loading platform, the manipulator automatic loading system is used for stacking and loading. After the loading is completed, the rear door of the carriage 1 is closed, and the large-displacement air pump set on the loading platform is connected through the fast inflation / exhaust port 401 to quickly inflate the air bags 2. After the inflation pressure reaches more than 0.01MPa (the inflation pressure of the air bags is between 0.01 and 0.03MPa, and the maximum thickness of the air bags is greater than the gap of the stacked goods in the carriage), the valve of the fast inflation / exhaust port 401 is closed, the inflation pipeline is disconnected, and the large-displacement air pump is stopped. Start the vehicle for transfer and transportation. During the transfer process, start the on-board air pump 3 installed in the cab, and continuously inflate the airbag 2 through the continuous inflation / exhaust port 402 to ensure the stability of the pressure in the airbag 2 and prevent the airbag 2 from losing pressure due to leakage of the airbag 2 and the connecting pipe, and losing the squeezing and holding effect on the goods. After arriving at the unloading warehouse, open the valve of the quick inflation / exhaust port 401, deflate the airbag 2, so that the airbag 2 loses its squeezing effect on the goods, so as to facilitate unloading. The operation of the automatic unloading system requires a certain gap between the goods and the wall of the carriage. The on-board air pump 3 in the cab is used to exhaust the airbag 2, so that the airbag 2 is tightly attached to the wall of the carriage 1, leaving enough gap between the goods and the carriage 1.
