Description

Technical Field

[0001] This invention belongs to the field of transportation equipment technology, specifically a flatbed transport vehicle for power storage. Background Technology

[0002] Flatbed trucks, as common mechanical equipment in existing technology, have applications in most fields, such as the handling of electrical equipment in power warehousing. Common flatbed trucks have a relatively simple structure, typically consisting only of a platform for placing items and wheels mounted at the bottom. Items are transferred by pulling the flatbed truck manually or using external mechanical equipment. However, when handling electrical equipment, some of which have many delicate internal structures, vibrations during transport can easily cause malfunctions. Furthermore, during the handling of electrical equipment, dust and moisture in the air can easily adhere to the outside of the equipment and even enter its interior, affecting the use of some structural components.

[0003] Existing patent CN114906195A discloses a power equipment transport vehicle, including: a handcart and a box; the handcart includes a base plate and a baffle plate disposed on the top edge of the base plate; the box is disposed on the base plate, and a first spring is disposed between the box and the base plate; the box is located inside the baffle plate, and a second spring is disposed between the box and the baffle plate; a slide rail is disposed at the bottom of the box to change the center of gravity of the box; at least two shelves for storing power equipment are disposed on the slide rail; the shelves are slidably connected to the slide rail via wheels, and the wheels are provided with locking devices for locking the shelves onto the slide rail. Although this application can provide shock absorption and cushioning for the power equipment, the power equipment needs to be placed inside the box to achieve dust and moisture protection. The packing and unpacking process is relatively complicated, which is not conducive to the transportation of power equipment. If the power equipment is transported exposed, it is not convenient for its dust and moisture protection.

[0004] Currently, some transport vehicles are equipped with sealed boxes (similar to box trucks) to place electrical equipment inside before transfer. However, the sealed boxes increase the overall size of the transport vehicle, making it unsuitable for use in warehouses. In addition, the sealed boxes usually only have an opening on one side, resulting in low efficiency in loading and unloading electrical equipment. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a power storage flatbed transport vehicle with high shock absorption effect, which avoids serious vibration during the transfer of power equipment and damage to the internal electronic components of the power equipment, facilitates the use of power equipment, and can effectively protect the power equipment through the set protective parts, preventing dust, moisture and other substances from entering the interior of the power equipment during the transfer process and affecting the use of the structure. At the same time, it facilitates the loading and unloading of power equipment and can effectively improve the transfer efficiency of power equipment, which can effectively solve the problems in the background art.

An air supply pipe communicating with the inner cavity of the protective component is provided on the side of the protective component, and an air jet port is opened on the side of the protective component. An air pump is fixedly installed on the side of the frame, and a connecting pipe communicating with the inner cavity of the cylinder is provided at the air outlet of the air pump. An air guide pipe communicating with the inner cavity of the cylinder is installed on the side of the cylinder, and the air guide pipe is connected to the air supply pipe through a pressure relief component.

[0008] As a preferred embodiment of the present invention, an mounting cavity is provided on the upper side of the frame, a bearing plate is installed in the mounting cavity, a bladder is provided below the bearing plate and located in the mounting cavity, and an air intake pipe communicating with its inner cavity is fixed on the lower side of the cylinder, with the end of the air intake pipe away from the cylinder communicating with the inner cavity of the bladder.

[0009] As a preferred embodiment of the present invention, the frame includes a push handle.

[0010] As a preferred embodiment of the present invention, one end of the bearing plate is provided with a slope, and the slope is provided on the side of the bearing plate away from the push handle.

[0011] As a preferred embodiment of the present invention, the pressure relief assembly includes a cylinder, the gas supply pipe is connected to the inner cavity of the cylinder, a sealing plug is slidably disposed in the cylinder, the sealing plug is used to seal the connection between the gas supply pipe and the cylinder, an elastic element is disposed on one side of the sealing plug and located in the cylinder, and the gas guide pipe is installed in the cylinder at a position away from the elastic element.

[0012] As a preferred embodiment of the present invention, the protective component includes a first hollow column and a second hollow column. The outer side of the second hollow column is in sealed contact with the inner side of the first hollow column, and a fastening screw for limiting the second hollow column is provided on the outer side of the first hollow column. The air supply pipe is connected to the inner cavity of the second hollow column, and air jets are provided on the sides of both the first hollow column and the second hollow column.

[0013] As a preferred embodiment of the present invention, a switch and a power supply component are also fixed on the side of the vehicle frame, and the air pump, the switch and the power supply component are connected in series to form the working circuit of the air pump.

[0014] As a preferred embodiment of the present invention, the protective components are disposed at the four corners of the mounting plate, and airflow is ejected between the air nozzles of two adjacent protective components to form a wind wall for protection.

[0015] As a preferred embodiment of the present invention, the middle part of the vehicle frame has a U-shaped structure.

[0016] As a preferred embodiment of the present invention, the telescopic end of the telescopic member is equipped with a support wheel.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The electric storage flatbed transport vehicle of the present invention has a high shock absorption effect, which avoids serious vibration during the transfer of electric equipment and damage to the internal electronic components of the electric equipment. It facilitates the use of electric equipment, and the protective parts can effectively protect the electric equipment, preventing dust, moisture and other substances from entering the interior of the electric equipment during the transfer process and affecting the use of the structure. At the same time, it facilitates the loading and unloading of electric equipment and can effectively improve the transfer efficiency of electric equipment.

[0019] 2. In the electric storage flatbed transport vehicle of the present invention, after the piston moves away from the connection between the air intake pipe and the cylinder, the gas enters the bladder through the air intake pipe. The bladder gradually expands as it is inflated. During the transportation of the electric equipment, the bladder plays a buffering role. At the same time, the telescopic component also plays a buffering role, which improves the shock absorption effect of the transport vehicle and avoids the electric equipment from being subjected to more severe vibrations during transportation, which could cause failure of the internal precision structure.

[0020] 3. In the electric storage flatbed transport vehicle of this invention, after the air pressure inside the bladder reaches its peak, some of the gas inside the cylinder enters the cylinder through the air guide pipe. As the air pump continues to work, the pressure inside the cylinder gradually increases. When the pressure exceeds the elastic force of the elastic element, the air pressure pushes the sealing plug to move inside the cylinder and squeezes the elastic element. After the sealing plug is removed from the connection between the air supply pipe and the cylinder, the gas enters the protective component through the air supply pipe and is ejected through the air jet on the side of the protective component. The ejected gas forms an air wall to block dust, moisture and other external environmental factors, thus facilitating the protection of the power equipment.

[0021] 4. The power storage flatbed transport vehicle of this invention adjusts the intensity of the ejected airflow by rotating the second hollow column to misalign the jet nozzles on the side of the second hollow column with those on the side of the first hollow column. When the jet nozzles on the side of the second hollow column are completely aligned with those on the side of the first hollow column, the space through which the gas can pass is larger, resulting in a weaker wind wall. As the jet nozzles on the side of the second hollow column gradually become misaligned with those on the side of the first hollow column, the space through which the gas can pass is smaller, the airflow is compressed, and a stronger wind wall is formed. The adjusted second hollow column is positioned by tightening bolts, facilitating the use of the protective components after adjustment. Attached Figure Description

[0035] Please see Figures 1-7 This invention provides a technical solution: a power storage flatbed transport vehicle, including a frame 1. Several sets of telescopic components 4 are provided on both sides of the frame 1, and support wheels 5 are installed at the telescopic ends of the telescopic components 4. When the telescopic components 4 are not extended, the bottom of the frame 1 is in contact with the ground. At this time, the loading height of the transport vehicle is low, facilitating the transfer of larger and heavier power equipment onto the transport vehicle. When the telescopic components 4 are extended, the bottom of the frame 1 gradually separates from the ground, facilitating the movement of the transport vehicle for transferring power equipment. The telescopic component 4 includes a cylinder 41 fixed to the side of the frame 1. A rod 42 is slidably provided at the bottom of the cylinder 41, and a piston 43 is fixed at the end of the rod 42, located inside the cylinder 41 and in sealed contact with the inner side of the cylinder 41. A mounting plate 8 is fixed to the top of the cylinder 41, and several sets of protective components 9 are provided on the upper side of the mounting plate 8.

[0036] In a preferred embodiment, four sets of protective components 9 are provided, and are respectively located at the four corners of the transport vehicle. The protective components 9 are provided with air supply pipes 10 communicating with their inner cavities on their sides, and air jets are provided on the sides of the protective components 9. The protective components 9 spray gas through the air jets to form a wind wall to protect the transported electrical equipment.

[0037] In one alternative embodiment, the jet nozzles on the side of the protective member 9 are opened toward the adjacent other protective members 9, that is, a wind wall is formed around the transport vehicle.

[0038] In one optional embodiment, an air pump 3 is fixedly installed on the side of the frame 1. The air outlet of the air pump 3 is provided with a connecting pipe 31 that communicates with the inner cavity of the cylinder 41. The air pump 3 supplies air to control the operation of the telescopic component 4. An air guide pipe 6 that communicates with the inner cavity of the cylinder 41 is installed on the side of the cylinder 41. The air guide pipe 6 is connected to the air supply pipe 10 through a pressure relief component. After the air pressure inside the transport vehicle reaches a certain peak value, the excess gas is released to the outside, and the released gas forms a wind wall to protect the electrical equipment.

[0039] In one alternative embodiment, the protective elements 9 are disposed at the four corners of the mounting plate 8, and airflow is ejected between the nozzles of two adjacent protective elements (9) to form a wind wall for protection.

[0040] In one optional embodiment, a mounting cavity is provided on the upper side of the frame 1, that is, the middle part of the frame 1 has a U-shaped structure. A support plate 7 is installed in the mounting cavity. The support plate 7 is used to place the transported electrical equipment, and the support plate 7 is movable up and down. A bladder 71 is provided below the support plate 7 and located in the mounting cavity. An air inlet pipe 72 communicating with its inner cavity is fixed on the lower side of the cylinder 41. The end of the air inlet pipe 72 away from the cylinder 41 is connected to the inner cavity of the bladder 71. After the piston 43 is removed from the connection between the air inlet pipe 72 and the cylinder 41, gas enters the bladder 71 through the air inlet pipe 72. The bladder 71 is inflated and gradually expands to play a buffering and shock-absorbing role.

[0041] In a preferred embodiment, the frame 1 includes a push handle to facilitate the movement of the transport vehicle, and a ramp is provided at one end of the bearing plate 7, which is located on the side of the bearing plate 7 away from the push handle, so that the ramp facilitates the loading and unloading of electrical equipment.

[0042] In one optional embodiment, the pressure relief assembly includes a cylinder 11, with an air supply pipe 10 communicating with the inner cavity of the cylinder 11. A sealing plug 12 is slidably disposed inside the cylinder 11, and the sealing plug 12 is used to seal the connection between the air supply pipe 10 and the cylinder 11. An elastic element 13 is disposed on one side of the sealing plug 12 and located inside the cylinder 11. The elastic element 13 is preferably a spring. The air guide pipe 6 is installed in the cylinder 11 at a position away from the elastic element 13. After the air pressure inside the bladder 71 reaches its peak value, part of the gas inside the cylinder 41 enters the cylinder 11 through the air guide pipe 6. As the air pump 3 continues to work, the pressure inside the cylinder 11 gradually increases. When the pressure is greater than the elastic force of the elastic element 13, the air pressure pushes the sealing plug 12 to move inside the cylinder 11 and squeezes the elastic element 13. After the sealing plug 12 is removed from the connection between the air supply pipe 10 and the cylinder 11, the gas enters the protective member 9 through the air supply pipe 10.

[0043] In one optional embodiment, the protective component 9 includes a first hollow column 91 and a second hollow column 92. The outer side of the second hollow column 92 is in sealed contact with the inner side of the first hollow column 91, and a fastening screw is provided on the outer side of the first hollow column 91 to limit the positioning of the second hollow column 92. The air supply pipe 10 is connected to the inner cavity of the second hollow column 92. Both the first hollow column 91 and the second hollow column 92 have air jets on their sides. By rotating the second hollow column 92, the air jets on the side of the second hollow column 92 are misaligned with the air jets on the side of the first hollow column 91, thereby adjusting the intensity of the ejected airflow.

[0044] In one optional embodiment, a switch and a power supply component 2 are also fixed on the side of the frame 1. The air pump 3, the switch and the power supply component 2 are connected in series to form the working circuit of the air pump 3. The setting of the power supply component 2 and the switch facilitates the use of the air pump 3.

[0045] When the telescopic component 4 is not inflated, the bottom of the frame 1 is in contact with the ground, and the bladder 71 is not inflated. The bearing plate 7 is set close to the ground. At this time, the bearing plate 7 is in the lowest position, which facilitates the transfer of large power equipment to this transport vehicle. There is no interception or protection around this transfer device. When transporting small power equipment, the power equipment can be moved from multiple sides at the same time, which improves the efficiency of loading and unloading power equipment in this transport vehicle. This transport vehicle is mainly used for protection around the sides. If it is necessary to protect the top of the transport vehicle, a top plate can be fixed on the top of the protective component 9.

[0046] After the power equipment is loaded, the air pump 3 is started by the switch. The air pump 3 fills the cylinder 41 with air through the connecting pipe 31. The gas compresses the piston 43 and moves the rod 42 to the outside, that is, the telescopic part 4 extends, so that the bottom of the frame 1 gradually separates from the ground, making it easier to move the transport vehicle to transfer the power equipment.

[0047] As the air pump 3 continues to pump air into the cylinder 41, causing the piston 43 to move downwards, once the piston 43 moves away from the connection between the air intake pipe 72 and the cylinder 41, the gas enters the bladder 71 through the air intake pipe 72. The bladder 71 gradually expands as it is inflated. During the transport of the power equipment, the bladder 71 acts as a buffer. At the same time, the telescopic component 4 also has a buffering effect, improving the shock absorption effect of this transport vehicle and preventing the power equipment from being subjected to severe vibrations during transport, which could cause malfunctions in the internal precision structure.

[0048] When the air pressure inside the bladder 71 reaches its peak, some of the gas inside the cylinder 41 enters the cylinder 11 through the air guide pipe 6. As the air pump 3 continues to work, the pressure inside the cylinder 11 gradually increases. When the pressure exceeds the elastic force of the elastic element 13, the air pressure pushes the sealing plug 12 to move inside the cylinder 11 and squeezes the elastic element 13. After the sealing plug 12 is removed from the connection between the air supply pipe 10 and the cylinder 11, the gas enters the protective element 9 through the air supply pipe 10 and is ejected through the jet nozzle on the side of the protective element 9. The ejected gas forms a wind wall to block dust, moisture and other substances in the external environment, which is conducive to the protection of electrical equipment.

[0049] By rotating the second hollow column 92, the jet nozzles on the side of the second hollow column 92 are misaligned with the jet nozzles on the side of the first hollow column 91, thus adjusting the intensity of the ejected airflow. When the jet nozzles on the side of the second hollow column 92 are completely aligned with the jet nozzles on the side of the first hollow column 91, the space through which the gas can pass through the jet nozzles is larger, and the resulting wind wall is weaker. As the jet nozzles on the side of the second hollow column 92 and the jet nozzles on the side of the first hollow column 91 are gradually misaligned, the space through which the gas can pass through the jet nozzles is smaller, the airflow is compressed, and the resulting wind wall is stronger. The adjusted second hollow column 92 is positioned by tightening bolts, facilitating the use of the adjusted protective component 9.
