Specific implementation manner

[0045] The present application discloses an energy storage type lifting trolley with adjustable height to adapt to the table tops of process equipment at different heights and reduce labor intensity.

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0047] The transformer is a large-scale equipment with a large weight. During the production process of the transformer, the transformer semi-finished products need to be transferred between different process equipment. At present, the table top heights of different process equipment for the transformer semi-finished products are different and cannot adapt to the energy storage type lifting trolley at the same height. Operators need to continuously carry the transformer semi-finished products up and down to carry the transformer semi-finished products onto the energy storage type lifting trolley.

[0048] Based on this, as Figures 1 to 3 shown, the energy storage type lifting trolley disclosed in the present application includes: a vehicle frame 1, a load platform 2, a driving assembly, and an energy storage device.

[0049] Among them, the vehicle frame 1 is the installation basis of the entire energy storage type lifting trolley. The shape, size, and material of the vehicle frame 1 can be set according to different needs and are all within the protection scope. In some embodiments, the vehicle frame 1 can be a frame structure to reduce the weight of the vehicle frame 1 and the processing cost; the vehicle frame 1 can also be a cabinet structure and form an accommodation space inside to accommodate tools or components with protection requirements, etc.

[0050] The load platform 2 is connected to the vehicle frame 1, and the load platform 2 can be lifted relative to the vehicle frame 1. It should be noted that the moving direction of the load platform 2 relative to the vehicle frame 1 is the direction of the height difference between the vehicle frame 1 and the tabletop of the semi-finished transformer process equipment, so as to change the height of the load platform 2 relative to the tabletop of the semi-finished transformer process equipment. See Figure 1 As shown, after the vehicle frame 1 is normally placed on the ground, the load platform 2 moves in the height direction relative to the vehicle frame 1. The load platform 2 can be adjusted in height relative to the vehicle frame 1, so as to change the height of the load platform 2 relative to the tabletop of the semi-finished transformer process equipment, so as to adapt to the heights of different semi-finished transformer process equipment tabletops, and try to make the height of the load platform 2 the same as that of the corresponding semi-finished transformer process equipment tabletop.

[0051] In the present application, the drive assembly is connected to the load platform 2 and is used to drive the load platform to lift relative to the vehicle frame 1. The energy storage device is connected to the drive assembly and is used to provide the energy required for the operation of the drive assembly. The drive assembly is connected to the load platform 2, and the drive assembly can stop driving within the lifting range of the load platform 2, and under the support of the drive assembly, the load platform 2 can hover within the lifting range.

[0052] Combined with the structure of the energy storage type lifting trolley described above, during the working process of the energy storage type lifting trolley, the energy storage device provides energy to the drive assembly, so that the drive assembly starts, and the drive assembly drives the load platform 2 to lift relative to the vehicle frame 1 until the load platform 2 reaches the required height, and the drive assembly stops working and can support the load platform 2 to hover.

[0053] In some embodiments, the lifting range of the load platform 2 is between 650 mm and 950 mm. Under the driving action of the drive assembly, the load platform 2 can lift between 650 mm and 950 mm, and under the support of the drive assembly, the load platform 2 can hover at any position between 650 mm and 950 mm.

[0054] In the energy storage type lifting trolley disclosed in the present application, the energy storage device provides energy to the drive assembly body, so that the drive assembly starts and drives the load platform 2 to lift relative to the vehicle frame 1, thereby changing the height of the load platform 2, so as to adjust the distance between the load platform 2 and the tabletop of the semi-finished transformer process equipment, reduce the distance between the load platform 2 and the tabletop of the semi-finished transformer process equipment, that is, reduce the distance for transporting the semi-finished transformer from the equipment tabletop to the load platform, thereby reducing the handling difficulty of the operator. In addition, the operator uses the energy storage type lifting trolley to transfer the semi-finished transformer between different process equipment, which can effectively improve the production efficiency of the transformer.

[0055] As Figures 1 to 3 shown in the embodiment, the drive assembly includes: a cylinder 4 and a control valve 51.

[0056] Among them, the main body of the air cylinder 4 is fixed to the vehicle frame 1, including but not limited to being fixed to the bottom plate 11 of the vehicle frame 1, and the telescopic rod of the air cylinder 4 is connected to the load platform 2. In some embodiments, the telescopic rod of the air cylinder 4 and the load platform 2 are connected by, including but not limited to, bonding, clamping or threaded connection. The control valve 51 is used to control the start and stop of the air cylinder 4 to adjust the height of the load platform 2.

[0057] In this application, the air cylinder 4 is used to adjust the height of the load platform 2, and the telescopic rod is used to support the load platform 2. Combining with the working principle of the air cylinder 4, if the gas in the air cylinder 4 is not discharged, the telescopic rod can maintain its position to support the load platform 2. In some embodiments, the air cylinder 4 can provide a supporting force for the load platform 2 with a dynamic load of 150 KG and a static load of 500 KG.

[0058] The shape and size of the load platform 2 can be set according to different needs. Exemplarily, the load platform 2 is a rectangular platform and can support a transformer workpiece with a maximum width of 800 mm and a maximum length of 2200 mm. Those skilled in the art can understand that the size of the workpiece that the load platform 2 can support is not limited to the above size, as long as it can support the largest size during the transformer processing.

[0059] In some embodiments, the energy storage device includes: an on-vehicle gas storage tank 3, a gas supply pipeline 31, a triple unit 32 and a quick connector 33.

[0060] Among them, the on-vehicle gas storage tank 3 is installed on the vehicle frame 1, including but not limited to being fixed to the bottom plate 11 of the vehicle frame 1. The on-vehicle gas storage tank 3 is communicated with the air cylinder 4 for inflating the air cylinder 4, and the control valve 51 is arranged between the on-vehicle gas storage tank 3 and the air cylinder 4.

[0061] The shape and size of the on-vehicle gas storage tank 3 can be set according to different needs. In some embodiments, the capacity of the on-vehicle gas storage tank 3 can meet the requirements of multiple lifts of the load platform 2. Exemplarily, when the on-vehicle gas storage tank 3 is full of gas, it can realize no less than 15 lifts of the load platform 2.

[0062] One end of the gas supply pipeline 31 is communicated with the on-vehicle gas storage tank 3, and a quick connector 33 is arranged at the other end of the gas supply pipeline 31. The gas supply pipeline 31 includes but not limited to a metal pipeline or a plastic pipeline. The gas supply pipeline 31 is hermetically communicated with the on-vehicle gas storage tank 3. The quick connector 33 at the other end of the gas supply pipeline 31 is used for quick detachable connection with a gas supply device. When the quick connector 33 is connected to the gas supply device, the gas in the gas supply device enters the on-vehicle gas storage tank 3 through the gas supply pipeline 31 to complete the gas collection of the on-vehicle gas storage tank 3. In this application, the quick connector 33 can be quickly detached from the gas supply device, which is beneficial to improving the inflation efficiency of the on-vehicle gas storage tank 3.

[0063] In some embodiments, the combination unit is arranged on the air supply pipeline 31, and the combination unit includes: an air filter, a pressure reducing valve, and an oiler. Among them, the pressure reducing valve can stabilize the air source pressure, keeping the air source in a constant state, and can reduce the damage to hardware such as valves or actuators caused by sudden changes in the air source pressure. The filter is used to clean the air source and can filter out moisture in the compressed air to prevent moisture from entering the device along with the gas. The oiler can lubricate the moving parts of the machine body and can lubricate parts where it is inconvenient to add lubricating oil, greatly extending the service life of the machine body.

[0064] In some embodiments, the drive assembly further includes: a pneumatic push-button valve 5. Among them, the pneumatic push-button valve 5 controls the opening and closing of the control valve 51, and the on-vehicle air storage tank 3 supplies air to the pneumatic push-button valve 5. In this application, the on-vehicle air storage tank 3 supplies air to the pneumatic push-button valve 5, the pneumatic push-button valve 5 controls the above-mentioned control valve 51, and controls the cylinder 4 through the control valve 51.

[0065] In order to facilitate the operator to control the pneumatic push-button valve 5, in some embodiments, the pneumatic push-button valve 5 is arranged on the armrest of the vehicle frame 1. By installing the pneumatic push-button valve 5 on the armrest of the vehicle frame 1, after the operator pushes the energy storage type lifting trolley to the preset position, the control valve 51 can be controlled by pressing the pneumatic push-button valve 5.

[0066] In some embodiments, the control valve 51 is a pneumatic three-position five-way valve, and the type of the control valve 51 can be set according to different needs and is within the protection scope.

[0067] In some embodiments, the drive assembly can also be other structures. Exemplarily, the drive assembly includes: a lead screw nut assembly and a motor.

[0068] Among them, the nut of the lead screw nut assembly is connected to the load platform 2. The nut and the load platform 2 can be connected through a connecting rod, enabling the nut to be located inside the vehicle frame 1 so that the load platform 2 will not collide with the lead screw during the movement. The lead screw of the lead screw nut assembly is threadedly connected to the nut, and the vehicle frame 1 has a limiting structure for restricting the rotation of the nut, and the motor drives the lead screw to rotate.

[0069] The driving method using the lead screw nut assembly can drive the load platform 2 to lift, and due to the threaded fit between the lead screw and the nut, the nut is fixed on the lead screw, thereby enabling the load platform 2 to hover at the required position. Exemplarily, the limiting structure includes, but is not limited to, a limiting sleeve on the vehicle frame 1 that is sleeved outside the nut and abuts against the outer surface of the nut. The limiting sleeve can restrict the rotation of the nut, thereby enabling the nut to move along the axis of the lead screw.

[0070] In some embodiments, the driving component may also be a linear motor. The output shaft of the linear motor is connected to the load platform 2, and the main body of the linear motor is fixed to the vehicle frame 1. Those skilled in the art can understand that the driving component can also be selected according to different needs, and all are within the protection scope.

[0071] When the above-mentioned driving component includes a motor or is a linear motor, the energy storage device in the present application is a power source, and the power source is fixed to the vehicle frame 1, connected to the motor, and supplies power to the motor. The power source is a rechargeable battery or a solar cell. The energy storage device in the present application is a rechargeable battery or a solar cell, which can realize the reuse of the energy storage device.

[0072] The vehicle frame 1 in some embodiments includes: a bottom plate 11 and a top plate 12.

[0073] Rollers 13 are provided on the bottom surface of the bottom plate 11. The rollers 13 include but are not limited to universal wheels. Exemplarily, there are four rollers 13, which are distributed on the bottom surface of the bottom plate 11. The top plate 12 is opposite to the bottom plate 11 and is connected by columns, so that the vehicle frame 1 forms a frame structure. The load platform 2 is liftably connected to the top plate 12, and the lifting direction of the load platform 2 is the direction of the line connecting the bottom plate 11 and the top plate 12.

[0074] See Figure 3 As shown, the load platform 2 is connected to the top plate 12 through a light axis guide rod 21. The first end of the light axis guide rod 21 is connected to the load platform 2. A buffer pad is sleeved on the first end of the light axis guide rod 21, and the buffer pad can abut against the load platform 2; the light axis guide rod 21 penetrates through the top plate 12, and the other end of the light axis guide rod 21 has a limit baffle that can abut against the top plate 12.

[0075] In some embodiments, the buffer pad includes but is not limited to a rubber pad, and the buffer pad is sleeved on the light axis guide rod 21, and the buffer pad is connected to the top plate load platform 2. The edge of the second end of the limit baffle is an outward-turning structure to prevent the light axis guide rod 21 from detaching from the top plate 12. Exemplarily, the load platform 2 is a rectangular plate, and there may be four light axis guide rods 21, which are arranged at the four top corners of the load platform 2, that is, the light axis guide rods 21 are arranged along the circumferential direction of the load platform 2.

[0076] Based on the above arrangement of the light axis guide rods 21, the driving component is arranged within the range surrounded by the light axis guide rods 21. Exemplarily, the driving component is arranged at the middle position of the rectangular plate.

[0077] In order to prevent the light axis guide rod 21 from tilting, in some embodiments, a guide seat is provided on the vehicle frame 1. The light axis guide rod 21 is arranged in the guide seat and can lift along the guide seat, and the guide seat has circumferential limitation with the light axis guide rod 21. The space between the light axis guide rod 21 and the guide seat is filled with oil to reduce wear.

[0078] In some embodiments, the optical axis guide rod 21 is a hollow shaft, and a graphene slip ring is provided at the position where the top plate 12 is used to cooperate with the optical axis guide rod 21 to reduce the wear between the optical axis guide rod 21 and the top plate 12.
