Description

Technical Field

[0001] The invention relates to the technical field of electric telescopic tools, and in particular to an electric push rod for efficient and stable transportation. Background Art

[0002] Electric linear actuator, also known as linear drive, is mainly composed of motor, push rod, control system and other mechanisms. It is a mechanical element that converts the rotational motion of the motor into linear motion. It is also one of the most basic components. The electric linear actuator can be controlled by the operator to perform linear motion at a fixed distance and speed. The application of electric linear actuator in the field of material transportation is mainly reflected in its ability to provide precise thrust and pull, which is suitable for pushing and pulling goods, thereby improving logistics efficiency. In warehousing and logistics centers, electric linear actuator can be used in automated conveying systems to realize automatic pushing and positioning of goods, reduce manpower requirements, and improve loading and unloading efficiency.

[0003] When the existing electric push rod pushes or pulls materials, due to the difference in weight of the materials to be loaded and unloaded, when loading and unloading heavier materials, the degree of wear between the screw and the push rod during rotation is affected by the weight of the materials, compared with the loading and unloading of lighter materials. It is necessary to add lubricating oil between the screw and the push rod to reduce wear. At the same time, metal debris generated by the wear of the screw and the push rod will remain in the lubricating oil, and the metal debris in the lubricating oil further causes secondary wear to the screw and the push rod. After long-term use, it is difficult to ensure the stability of the electric push rod when pushing or pulling materials. At the same time, when loading and unloading materials of different weights, it is also necessary to replace different types of lubricating oils. Therefore, the present application provides an electric push rod for efficient and stable transportation to meet the needs. Summary of the invention

At the same time, metal debris generated by the wear of the screw and the push rod will remain in the lubricating oil, and the metal debris in the lubricating oil will further cause secondary wear to the screw and the push rod.

[0036] like Figure 1 and Fig. 9 As shown, an embodiment of the present invention provides an electric push rod for efficient and stable transportation, including a mounting base 1, a control module 2 is installed on the top of the mounting base 1, a mounting shell 3 is installed on the top of the mounting base 1, a motor 4 is installed on the top of the inner wall of the mounting base 1, a bevel gear set 5 is installed at one end of the motor 4, one end of the motor 4 is connected to one group of bevel gears in the bevel gear set 5, a transmission rod 6 is installed on the top of the other group of bevel gears in the bevel gear set 5, the transmission rod 6 is nested and installed on the top of the mounting base 1, a screw 7 is installed on the top of the transmission rod 6, and a push rod 8 is threadedly sleeved on the outer surface of the screw 7; a filter component 9 is installed on the top of the mounting shell 3, and the filter component 9 is used to filter the lubricating oil in the internal cavity of the mounting shell 3; a lubricating component 10 is installed on the side of the mounting shell 3, and the lubricating component 10 is used to replenish the lubricating oil in the internal cavity of the mounting shell 3; a switching component 11 is installed on the top of the lubricating component 10, and the switching component 11 is used to switch when the lubricating component 10 replenishes the lubricating oil in the internal cavity of the mounting shell 3.

[0037] By setting up the filter component 9, the metal debris on the inner surface of the filter plate 98 is scraped off by the cleaning brush 99, so as to prevent the metal debris from entering the exchange barrel 101 along with the lubricating oil, thereby increasing the repeated service life of the lubricating oil and reducing the use cost of the lubricating oil. At the same time, the fallen metal debris is collected and processed by the collecting box 910, so as to further increase the service life of the electric push rod. By setting up the lubricating component 10, the lubricating oil can fully enter between the screw 7 and the push rod 8, so as to ensure the lubrication degree between the screw 7 and the push rod 8, reduce the wear between the screw 7 and the push rod 8, and ensure the service life of the electric push rod when loading and unloading materials. By setting up the switching component 11, when loading and unloading materials of different weights, it is possible to switch between the two types of lubricating oil according to the actual weight of the materials to be loaded and unloaded, so as to ensure the lubrication protection effect between the screw 7 and the push rod 8 and improve the use flexibility of the electric push rod when loading and unloading materials.

[0038] like Figures 3 to 5 As shown, the filter assembly 9 includes a trigger plate 91, an elastic telescopic rod 92 is installed at the bottom of the trigger plate 91, and the elastic telescopic rod 92 is installed at the top of the push rod 8. The trigger plate 91 is elastically connected to the top of the push rod 8 through the elastic telescopic rod 92. A rack 93 is fixedly installed on one side of the trigger plate 91, and an inner ratchet 94 is meshingly installed on one side of the rack 93. The inner ratchet 94 is installed on one side of the top of the mounting shell 3, and a bevel gear set 95 is installed on one side of the inner ratchet 94. The bevel gear set 95 is installed on one side of the top of the mounting shell 3. One end of one of the bevel gears in the wheel set 2 95 is connected to the inner ratchet 94, and a flat gear 2 96 is installed at the bottom end of the other bevel gear in the bevel gear set 2 95. The flat gear 2 96 is installed on one side of the top of the mounting shell 3. A gear ring 97 is meshingly installed on one side of the flat gear 2 96. The gear ring 97 is nested in the top of the mounting shell 3. A filter plate 98 is installed at the bottom end of the gear ring 97. A cleaning brush 99 is in contact with the inner side of the filter plate 98. A collection box 910 is installed at the bottom end of the cleaning brush 99. The collection box 910 is threadedly installed at the bottom end of the mounting shell 3.

[0039] Under the continuous squeezing action of the material, the bottom end of the material approaches and squeezes the trigger plate 91. The trigger plate 91 slides downward under the force, while driving the elastic telescopic rod 1 92 at the bottom to contract. The trigger plate 91 slides down while driving the rack 93 to slide synchronously. Under the sliding action of the rack 93, the rack 93 meshes with the inner ratchet 94 and causes the inner ratchet 94 to rotate. When the inner ratchet 94 rotates, the input end is driven to rotate synchronously. When the input end of the bevel gear set 2 95 rotates, it meshes with the output end of the bevel gear set 2 95 and rotates synchronously. When the output end of the bevel gear set 2 95 rotates, it drives The movable flat gear 96 rotates synchronously, and the flat gear 96 drives the filter plate 98 at the bottom end to rotate in the mounting housing 3, so that the contact surface of the filter plate 98 and the lubricating oil when entering rotates and changes position. At the same time, the inner wall of the filter plate 98 contacts the cleaning brush 99 when the filter plate 98 rotates. Under the rotation of the filter plate 98, the cleaning brush 99 cleans the metal debris trapped at the contact surface of the filter plate 98 and the lubricating oil when entering, so that the metal debris falls along the inner wall of the filter plate 98 to the bottom end of the inner wall of the collection box 910, completing the collection of the trapped metal debris;

[0040] The lubricating oil passes through the filter plate 98 when circulating and exchanging between the mounting shell 3 and one of the groups of exchange barrels 101. Under the filtering effect of the filter plate 98, the metal debris carried by the lubricating oil after entering the mounting shell 3 is retained on the inner wall of the filter plate 98, thereby preventing the metal debris mixed in the lubricating oil from being brought into the exchange barrel 101 on the other side when the lubricating oil is sucked into the exchange barrel 101 on the other side.

[0041] By setting the elastic cooperation between the trigger plate 91 and the elastic telescopic rod 1 92, utilizing the force when the trigger plate 91 contacts the material, through the meshing linkage between the inner ratchet 94, the bevel gear set 2 95, the flat gear 2 96 and the gear ring 97, the gear ring 97 drives the filter plate 98 to rotate at intervals, so that when the lubricating oil in the mounting shell 3 is extracted from the mounting shell 3, the metal debris carried in the lubricating oil can be intercepted by the filter plate 98, and at the same time, in conjunction with the interval rotation effect of the filter plate 98, the metal debris on the inner surface of the filter plate 98 is scraped off by the cleaning brush 99 to prevent the metal debris from entering the exchange barrel 101 with the lubricating oil, thereby increasing the repeated service life of the lubricating oil and reducing the use cost of the lubricating oil. At the same time, the fallen metal debris is collected and processed by the collecting box 910. After the material loading and unloading is completed, when the electric push rod is disassembled for maintenance, the collecting box 910 is disassembled and the metal debris and other impurities collected in the collecting box 910 are centrally processed, thereby further increasing the service life of the electric push rod.

[0042] like Figure 6As shown, the lubrication assembly 10 includes an exchange barrel 101, and an elastic telescopic rod 1010 is installed at the bottom of the exchange barrel 101. The elastic telescopic rod 1010 is elastically installed at the top of the mounting base 1. The exchange barrel 101 is elastically connected to the top of the mounting base 1 through the elastic telescopic rod 1010. The number of exchange barrels 101 is set to two groups, and the two groups of exchange barrels 101 are arranged at equal angles on the top of the mounting base 1. Each group of exchange barrels 101 is symmetrically arranged along the mounting shell 3. One side of the exchange barrel 101 is connected to the inside of the mounting shell 3 through a hose. A liquid storage barrel 102 is fixedly installed on the top of the exchange barrel 101, and the liquid storage barrel 102 is connected to the exchange barrel 101 through a hose. A turbofan 103 is rotatably installed in the internal cavity of the liquid storage barrel 102, and a screw 104 is installed at the bottom of the turbofan 103. The screw 104 is nested and installed in the exchange barrel 101. At the top of the inner wall of the exchange barrel 101, a piston disk 105 is threadedly sleeved on the outer surface of the second screw 104, and the outer surface of the piston disk 105 contacts the inner wall of the exchange barrel 101. Two groups of liquid storage barrels 102 are installed on the top of the two groups of exchange barrels 101. The rotation directions of the two groups of turbofans 103 in the two groups of liquid storage barrels 102 are opposite. One side of the liquid storage barrel 102 is connected with a liquid inlet barrel 106 through a hose, and the liquid inlet barrel 106 is fixedly installed on one side of the exchange barrel 101. The top of the liquid storage barrel 102 is connected with a liquid outlet barrel 107 through a hose, and the liquid outlet barrel 107 is fixedly installed on the top of the liquid storage barrel 102. The bottom end of the inner wall of the liquid outlet barrel 107 is elastically connected with a spring 108, and a push plate 109 is elastically installed on the top of the spring 108. The push plate 109 is nested and installed on the top of the liquid outlet barrel 107, and the elasticity of the spring 108 is less than the elasticity of the elastic telescopic rod 1010.

[0043] The user places the material to be conveyed on the top of the push plate 109. Under the action of the material's own weight, the material pushes the push plate 109 to slide downward. Under the action of the block 117, the distance between the push plate 109 and the top of the liquid outlet barrel 107 at the push plate 109 at the top of one group of exchange barrels 101 has been limited. Therefore, under the action of the material's own weight, the material squeezes the push plate 109 to slide down, and the push plate 109 pushes the liquid outlet barrel 107, the liquid storage barrel 102 and the exchange barrel 101 to slide downward as a whole through the block 117. While the exchange barrel 101 slides, the elastic telescopic rod 1010 at the bottom of the exchange barrel 101 contracts. Under the continuous squeezing of the material, the material gradually approaches and contacts the push plate 109 at the top of the other group of exchange barrels 101. Since the elasticity of the spring 108 at the bottom of the push plate 109 is less than the elasticity of the elastic telescopic rod 1010, the material pushes the push plate 109 to slide nested in the top of the liquid outlet barrel 107, and the spring 108 contracts while the push plate 109 slides.

[0044] The push plate 109 slides while squeezing the oil in the liquid outlet barrel 107. Under the squeezing action of the push plate 109, the oil in the liquid outlet barrel 107 enters the liquid storage barrel 102 through the hose. Under the continuous squeezing action of the push plate 109, the oil enters the liquid inlet barrel 106 from the liquid storage barrel 102. In this process, the oil passes through the turbofan 103 in the liquid storage barrel 102, causing the turbofan 103 to rotate. The rotation of the turbofan 103 drives the screw 104 to rotate synchronously. Under the rotation action of the screw 104, the piston disc 105 threadedly sleeved on the outer surface of the screw 104 slides downward in the direction of the screw 104, and the active As the plug disc 105 slides, the lubricating oil stored in the exchange barrel 101 is squeezed into the installation shell 3 through the hose. Similarly, the other set of turbofans 103 rotates in the opposite direction under the action of the oil, so that the turbofan 103 drives the screw rod 104 to rotate in the opposite direction. Under the reverse rotation of the screw rod 104, the piston disc 105 on the outer surface of the screw rod 104 slides upward along the direction of the screw rod 104. Under the action of the negative pressure generated, the lubricating oil in the installation shell 3 is sucked into the exchange barrel 101 on the other side, so that the lubricating oil is circulated and exchanged in the installation shell 3 and one set of exchange barrels 101, so that the lubricating oil can fully contact the screw rod 1 7 and the push rod 8.

[0045] By setting up two groups of exchange barrels 101, two different types of lubricating oils are separately stored, and at the same time, the two groups of exchange barrels 101 are arranged at different heights, and the elastic cooperation between the exchange barrels 101 and the elastic telescopic rod 1010 is utilized to realize the switching between the two different types of lubricating oils in the two groups of exchange barrels 101. At the same time, through the two exchange barrels 101 arranged at a medium angle in each group of exchange barrels 101, the extrusion force when the push plate 109 contacts the material is utilized to realize the circulation exchange of the lubricating oil between the two exchange barrels 101 and the mounting shell 3, and at the same time, the inflow and outflow of the lubricating oil are guided. Through the exchange and guidance of the lubricating oil between the two exchange barrels 101 and the mounting shell 3, the lubricating oil can fully enter between the screw 1 7 and the push rod 8, thereby ensuring the lubrication degree between the screw 1 7 and the push rod 8. When the electric push rod loads and unloads heavy materials, the wear between the screw 1 7 and the push rod 8 is reduced, thereby ensuring the service life of the electric push rod when loading and unloading materials.

[0046] like Figures 7 to 9As shown, the switching assembly 11 includes a rotating disk 111, which is sleeved on the outer surface of the liquid outlet barrel 107. A gear disk 112 is installed on the top of the rotating disk 111. A bevel gear 113 is meshed and installed on one side of the gear disk 112. The bevel gear 113 is installed on the top of the liquid outlet barrel 107. The number of bevel gears 113 is set to two groups. The two groups of bevel gears 113 are arranged at equal angles on the top of the liquid outlet barrel 107. A screw rod 114 is installed at one end of the bevel gear 113. A sliding base 115 is threadedly sleeved on the outer surface of the screw rod 114. A limiting rod 116 is sleeved on the outer surface of the sliding base 115. The limiting rod 116 It is fixedly installed on the top of the liquid discharge barrel 107, and a block 117 is installed at one end of the sliding base 115. The top of the block 117 contacts the push plate 109. The number of the blocks 117 is set to two groups. The two groups of blocks 117 are arranged at equal angles on the top of the liquid discharge barrel 107. The other end of one group of bevel gears 113 is installed with a bevel gear set 3 118 through a connecting rod. One end of one group of bevel gears in the bevel gear set 3 118 is connected to the other end of the bevel gear 1 113 through a connecting rod. The number of the bevel gear set 3 118 is set to two groups. The other group of bevel gears in the two groups of bevel gear sets 3 118 are connected by a rotating rod 119.

[0047] After the user places the device at the installation position, the user fixes the installation base 1 as a whole by a fixing tool. At the same time, the user then rotates the rotating disk 111 according to the actual weight of the material to be transported. The rotating disk 111 drives the geared disk 112 to rotate synchronously at the top of one group of liquid outlet barrels 107. Under the rotation of the geared disk 112, the two groups of bevel gears 113 are engaged with the geared disk 112 to rotate. The rotation of the bevel gear 113 drives the screw rod 3 114 at one end to rotate synchronously. Under the rotation of the screw rod 3 114, the sliding base 115 sleeved on the outer surface of the screw rod 3 114 slides in the direction of the limiting rod 116. The sliding base 115 drives the block 117 to approach and contact the surface of the push plate 109 while sliding. The distance between the push plate 109 and the top of the liquid outlet barrel 107 is limited by the two groups of blocks 117.

[0048] When one of the bevel gear sets 113 rotates, it drives the input end of one of the bevel gear sets 3 118 to rotate synchronously. When the input end of the bevel gear set 3 118 rotates, it meshes with the output end of the bevel gear set 3 118 to rotate. When the output end of the bevel gear set 3 118 rotates, it drives the input end of another bevel gear set 3 118 to rotate synchronously through the rotating rod 119. When the input end of another bevel gear set 3 118 rotates, it meshes with the output end of another bevel gear set 3 118 to rotate synchronously. When the output end of another bevel gear set 3 118 rotates, it meshes with the rotation of the gear disk 112 at the top of another group of liquid discharge barrels 107. Similarly, when another group of gear disks 112 rotates, it meshes with the two groups of bevel gears 113 at the top of another group of liquid discharge barrels 107 to rotate, so that the two groups of blocks 117 at the top of another group of liquid discharge barrels 107 limit the distance between the top of the group of liquid discharge barrels 107 and the push plate 109.

[0049] By setting the block 117 and utilizing the rotational cooperation among the toothed disk 112, the bevel gear one 113 and the screw three 114, when loading and unloading materials, the user can limit the distance between the push plate 109 and the top of the liquid outlet barrel 107 by rotating the rotating disk 111 according to the actual weight difference of the materials to be loaded and unloaded through the block 117, and at the same time cooperate with the lubrication component 10 to achieve the switching effect of the two types of lubricating oil in the two groups of exchange barrels 101. When loading and unloading materials of different weights, the two types of lubricating oil can be switched according to the actual weight of the materials to be loaded and unloaded, thereby ensuring the lubrication protection effect between the screw one 7 and the push rod 8 while improving the flexibility of the electric push rod in loading and unloading materials.

[0050] The working principle of the technical solution provided by the present invention is as follows:

[0051] After the user places the device at the installation position, the user fixes the installation base 1 as a whole with a fixing tool. At the same time, the user then rotates the rotating disk 111 according to the actual weight of the material to be conveyed. The rotating disk 111 drives the geared disk 112 to rotate synchronously at the top of one group of liquid outlet barrels 107. Under the rotation of the geared disk 112, the two groups of bevel gears 113 are engaged with the geared disk 112 to rotate. The rotation of the bevel gear 113 drives the screw rod 3 114 at one end to rotate synchronously. Under the rotation of the screw rod 3 114, the sliding base 115 sleeved on the outer surface of the screw rod 3 114 slides in the direction of the limiting rod 116. When the sliding base 115 slides, it drives the block 117 to approach and contact the surface of the push plate 109, and the distance between the push plate 109 and the top of the liquid outlet barrel 107 is limited by the two groups of blocks 117.

[0052] When one of the bevel gear sets 113 rotates, it drives the input end of one of the bevel gear sets 3 118 to rotate synchronously. When the input end of the bevel gear set 3 118 rotates, it meshes with the output end of the bevel gear set 3 118 to rotate. When the output end of the bevel gear set 3 118 rotates, it drives the input end of another bevel gear set 3 118 to rotate synchronously through the rotating rod 119. When the input end of another bevel gear set 3 118 rotates, it meshes with the output end of another bevel gear set 3 118 to rotate synchronously. When the output end of another bevel gear set 3 118 rotates, it meshes with the rotation of the gear disk 112 at the top of another group of liquid discharge barrels 107. Similarly, when another group of gear disks 112 rotates, it meshes with the two groups of bevel gears 113 at the top of another group of liquid discharge barrels 107 to rotate, so that the two groups of blocks 117 at the top of another group of liquid discharge barrels 107 limit the distance between the top of the group of liquid discharge barrels 107 and the push plate 109.

[0053] Then the user places the material to be conveyed on the top of the push plate 109. Under the action of the material's own weight, the material pushes the push plate 109 to slide downward. Under the action of the block 117, the distance between the push plate 109 and the top of the liquid outlet barrel 107 at the push plate 109 at the top of one group of exchange barrels 101 has been limited. Therefore, under the action of the material's own weight, the material squeezes the push plate 109 to slide down, and the push plate 109 pushes the liquid outlet barrel 107, the liquid storage barrel 102 and the exchange barrel 101 to slide downward as a whole through the block 117. While the exchange barrel 101 slides, the elastic telescopic rod 1010 at the bottom of the exchange barrel 101 contracts. Under the continuous squeezing of the material, the material gradually approaches and contacts the push plate 109 at the top of the other group of exchange barrels 101. Since the elasticity of the spring 108 at the bottom of the push plate 109 is less than the elasticity of the elastic telescopic rod 1010, the material pushes the push plate 109 to slide nested in the top of the liquid outlet barrel 107, and the spring 108 contracts while the push plate 109 slides.

[0054] The push plate 109 slides while squeezing the oil in the liquid outlet barrel 107. Under the squeezing action of the push plate 109, the oil in the liquid outlet barrel 107 enters the liquid storage barrel 102 through the hose. Under the continuous squeezing action of the push plate 109, the oil enters the liquid inlet barrel 106 from the liquid storage barrel 102. In this process, the oil passes through the turbofan 103 in the liquid storage barrel 102, causing the turbofan 103 to rotate. The rotation of the turbofan 103 drives the screw 104 to rotate synchronously. Under the rotation action of the screw 104, the piston disc 105 threadedly sleeved on the outer surface of the screw 104 slides downward in the direction of the screw 104, and the active As the plug disc 105 slides, the lubricating oil stored in the exchange barrel 101 is squeezed into the installation shell 3 through the hose. Similarly, the other set of turbofans 103 rotates in the opposite direction under the action of the oil, so that the turbofan 103 drives the screw rod 104 to rotate in the opposite direction. Under the reverse rotation of the screw rod 104, the piston disc 105 on the outer surface of the screw rod 104 slides upward along the direction of the screw rod 104. Under the action of the negative pressure generated, the lubricating oil in the installation shell 3 is sucked into the exchange barrel 101 on the other side, so that the lubricating oil is circulated and exchanged in the installation shell 3 and one set of exchange barrels 101, so that the lubricating oil can fully contact the screw rod 1 7 and the push rod 8.

[0055] The lubricating oil passes through the filter plate 98 when circulating and exchanging between the mounting shell 3 and one of the groups of exchange barrels 101. Under the filtering effect of the filter plate 98, the metal debris carried by the lubricating oil after entering the mounting shell 3 is retained on the inner wall of the filter plate 98, thereby preventing the metal debris mixed in the lubricating oil from being brought into the exchange barrel 101 on the other side when the lubricating oil is sucked into the exchange barrel 101 on the other side.

[0056] Under the continuous squeezing action of the material, the bottom end of the material approaches and squeezes the trigger plate 91. The trigger plate 91 slides downward under the force, while driving the elastic telescopic rod 1 92 at the bottom to contract. The trigger plate 91 slides down while driving the rack 93 to slide synchronously. Under the sliding action of the rack 93, the rack 93 meshes with the inner ratchet 94 and causes the inner ratchet 94 to rotate. When the inner ratchet 94 rotates, the input end is driven to rotate synchronously. When the input end of the bevel gear set 2 95 rotates, it meshes with the output end of the bevel gear set 2 95 and rotates synchronously. When the output end of the bevel gear set 2 95 rotates, it drives The movable flat gear 96 rotates synchronously, and the flat gear 96 drives the filter plate 98 at the bottom to rotate in the mounting shell 3 while rotating, so that the contact surface between the filter plate 98 and the lubricating oil when entering rotates and changes position. At the same time, the filter plate 98 rotates and the inner wall contact cleaning brush 99 of the filter plate 98 rotates. Under the rotation of the filter plate 98, the cleaning brush 99 cleans the metal debris trapped at the contact surface between the filter plate 98 and the lubricating oil when entering, so that the metal debris falls along the inner wall of the filter plate 98 to the bottom end of the inner wall of the collection box 910, thereby completing the collection of the trapped metal debris.

[0057] Subsequently, the user starts the motor 4 through the control module 2. After starting, the motor 4 drives the input end of the bevel gear set 5 to rotate. While the input end of the bevel gear set 5 rotates, it engages with the output end of the bevel gear set 5 and rotates synchronously. While the output end of the bevel gear set 5 rotates, it drives the screw 7 to rotate through the transmission rod 6. Under the rotation of the screw 7, the push rod 8 slides upward along the direction of the screw 7. While the push rod 8 slides, it drives the trigger plate 91 at the top to slide synchronously. While the trigger plate 91 slides along with the push rod 8, it drives the material at the top of the trigger plate 91 to slide synchronously, thereby completing the loading and unloading of the materials.
