They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0020] Embodiment 1
[0021] like Figure 1As shown, the first embodiment includes a lower crossbeam conveying device body 1, which includes a horizontal guide rail 11 laid on the ground; an anti-tilt assembly 12 for transporting goods arranged on the horizontal guide rail 11, and the anti-tilt assembly 12 moves along the length direction of the horizontal guide rail 11, and the anti-tilt assembly 12 includes a load-bearing bearing 124, and the load-bearing bearing 124 is provided with a lubrication point for injecting grease; an oil injection assembly 13 connected to the lubrication point, and the oil injection assembly 13 includes an oil pump 132 and a grease injection pipe 133 connected to the oil pump 132, and the oil pump 132 can inject grease into the lubrication point through the grease injection pipe 133 in a timely and quantitative manner.
[0022] Specifically, the horizontal guide rail 11 is laid on the floor of the warehouse according to the layout of the warehouse, and the ground of the anti-tilt assembly 12 is connected to the top surface of the horizontal guide rail 11, so that the anti-tilt assembly 12 can move along the horizontal guide rail 11 under the push of external power, and then the horizontal guide rail 11 can stably transport the anti-tilt assembly 12 to move along a fixed horizontal track; wherein, the anti-tilt assembly 12 and the horizontal guide rail 11 are connected by rollers provided with load-bearing bearings 124 to form rolling friction, and heavy mass goods placed on the anti-tilt assembly 12 will apply pressure to the horizontal guide rail 11 through the rollers provided with load-bearing bearings 124, so that the load-bearing bearings 124 require a large amount of lubricating oil to keep the anti-tilt assembly 12 able to move along the horizontal guide rail 11 with less resistance.
[0023] Secondly, the bearing includes an inner ring, an outer ring, rolling elements (steel balls) and a retaining frame. The load-bearing bearing 124 is installed on the bearing seat. A grease hole is usually formed on the bearing seat. The grease hole is located above the outer ring so that the grease can flow smoothly into the interior of the load-bearing bearing 124. The load-bearing bearing 124 gradually consumes grease during rotation to reduce rolling friction. Therefore, grease needs to be injected regularly. Since the space for storing grease in the load-bearing bearing 124 is fixed, grease needs to be injected in a quantitative manner.
[0024] Secondly, under the control of the control element, the oil pump 132 controls the flow state of the grease pumped out by itself, that is, the output flow rate and output time, so that the oil pump 132 can quantitatively and regularly inject the grease into the grease injection pipe 133, and the grease injection pipe 133 then transports the grease to various lubrication points to lubricate the load-bearing bearings 124. The grease flow rate, output time and gap output by the oil pump 132 are gradually adjusted according to the production site to ensure that each load-bearing bearing 124 can be injected with a sufficient amount of grease, and to ensure that the load-bearing bearing 124 always stores grease during the rotation process, so as to avoid the lack of grease in the load-bearing bearing 124, which aggravates wear, generates excessive heat, and reduces its service life.
[0025] like Figure 2 a and Figure 2 As shown in b, Figure 2 b in Figure 2 In the enlarged view of the structure at C in a, the cross-section of the horizontal guide rail 11 is I-shaped; the anti-roll assembly 12 also includes an anti-roll plate 122 arranged on the horizontal guide rail 11, and the anti-roll plate 122 is perpendicular to the length direction of the horizontal guide rail 11. The end of the anti-roll plate 122 connected to the horizontal guide rail 11 forms a penetrating groove, and the groove is at least connected to a part of the protrusion of the horizontal guide rail 11. The convex surface of the horizontal guide rail 11 can apply a vertical downward force to the anti-roll plate 122.
[0026] Specifically, the horizontal guide rail 11 is laid on the ground to provide a support surface for the sliding of the anti-roll assembly 12, and its upper and lower parts protrude from the middle part respectively; secondly, the anti-roll plate 122 slides along the horizontal guide rail 11, and is perpendicular to the length direction of the horizontal guide rail 11, and the position where it contacts the horizontal guide rail 11 forms a groove for the horizontal guide rail 11 to pass through the anti-roll plate 122, and the middle dimension of the cross-section of the groove is larger than the dimension of its opening side, and its cross-section can be the same as the cross-section of the horizontal guide rail 11, or it can be the same as the shape and dimension of the upper half of the cross-section of the horizontal guide rail 11, so that the open side of the groove can limit the protrusion of the horizontal guide rail 11 to its own middle part, and then the protrusion of the horizontal guide rail 11 can limit the rotation of the groove, and then limit the rotation of the anti-roll plate 122 relative to the horizontal guide rail 11, thereby achieving the anti-roll effect of the anti-roll plate 122.
[0027] Furthermore, the anti-roll assembly 12 also includes: a transverse slide 121, anti-roll plates 122 are arranged at both ends of the transverse slide 121, and the length direction of the transverse slide 121 is the same as the length direction of the horizontal guide rail 11; and a conveying support wheel 123 arranged on the anti-roll plate 122, the side of the conveying support wheel 123 is in contact with the horizontal guide rail 11, the axis of the conveying support wheel 123 is perpendicular to the length direction of the horizontal guide rail 11, and the load-bearing bearing 124 is arranged on the radial inner side of the conveying support wheel 123.
[0028] Specifically, two anti-roll plates 122 are fixedly connected to the two ends of the transverse slide 121 by bolts, and the two anti-roll plates 122 form an anti-roll structure through a connecting plate, so that the transverse slide 121 is slidingly connected to the horizontal guide rail 11 through the anti-roll structure and achieves an anti-roll effect, and both ends of the transverse slide 121 can slide along the length direction of the horizontal guide rail 11.
[0029] Secondly, the anti-tilt structures at both ends of the transverse slide 121 are connected to the conveying support wheels 123 by bolts. The conveying support wheels 123 are symmetrically arranged on both sides of the horizontal guide rail 11 with the center line of the horizontal guide rail 11, and the side surfaces of the conveying support wheels 123 form rolling friction with the side surfaces of the upper half of the horizontal guide rail 11, so that the side surfaces of the conveying support wheels 123 can apply pressures of the same magnitude and opposite directions to the side surfaces of the upper half of the horizontal guide rail 11, thereby limiting the lateral movement of the anti-tilt plate 122 relative to the horizontal guide rail 11, so that the degree of freedom of the transverse slide 121 relative to the horizontal guide rail 11 is only in the length direction, thereby ensuring the accuracy of the movement of the transverse slide 121 along the horizontal guide rail 11.
[0030] Secondly, the conveying support wheel 123 is connected to the anti-tilt structure through the load-bearing bearing 124, so that it is always in rolling friction with the horizontal guide rail 11, thereby reducing the friction force during the movement of the transverse slide 121 and reducing heat generation.
[0031] like Figure 3 As shown, the grease injection pipeline 133 includes a pipeline joint 1331 connected to the oil pump 132. The oil pump 132 injects grease into the pipeline joint 1331. The pipeline joint 1331 transports the grease to the first diversion joint 1333 through the oil pipe 1332. The first diversion joint 1333 divides the grease into at least two parts and transports them to the second diversion joint 1334 through the oil pipe 1332. The second diversion joint 1334 divides the grease into at least two parts and transports them to the oil nozzle 1335 through the oil pipe 1332. The grease is injected into the lubrication point through the oil nozzle 1335.
[0032] Specifically, the oil pump 132 is connected to a detachable straight-through joint through a ferrule-type right-angle joint, and then connected to the oil pipe 1332 to form a main oil circuit, so that the oil pipe 1332 can change the flow direction of the grease output by the oil pump 132, and it is convenient to replace the oil pipe 1332 and the pipe joint 1331 for replacement or cleaning. The oil pipe 1332 of the main oil circuit divides the flow path of the grease into four parts evenly through the first diversion joint 1333. The first diversion joint 1333 transports the diverted grease to the second diversion joint 1334 through the oil pipe 1332. The second diversion joint 1334 divides the grease into sixteen parts in total, so that the oil pump 132 can output sixteen parts of the same volume of grease at the same time, and inject it into the lubrication points of sixteen load-bearing bearings 124 at the same time through the oil nozzle 1335. Among them, four load-bearing bearings 124 are respectively located at the conveying support wheels 123 at both ends of the transverse slide 121, and then the oil nozzle 1335 injects grease into the lubrication points therein respectively.
[0033] Furthermore, the oil injection assembly 13 also includes: an oil tank 131 connected to the oil pump 132 ; and a pressure switch 134 connected to the oil pipe 1332 .
[0034] Specifically, the oil tank 131 stores grease, and the oil pump 132 transports the grease in the oil tank 131 to sixteen lubrication points; secondly, the internal pressure of the grease injection pipe 133 is the same. When the grease is blocked in the oil nozzle 1335, the oil pump 132 continues to transport the grease, causing the internal pressure of the grease injection pipe 133 to increase, thereby triggering the pressure switch 134 to shut down the oil pump 132, thereby preventing the internal pressure of the grease injection pipe 133 from continuing to increase and causing the oil pipe 1332 to rupture, causing grease leakage, which not only causes waste but also pollutes the working environment.
[0035] The oil filling assembly 13 further includes: a low oil level detector 136 for detecting the remaining grease in the oil tank 131 ; and a PLC 135 electrically connected to the oil pump 132 , and the PLC 135 is capable of controlling the output flow rate and output time of the oil pump 132 .
[0036] Specifically, the low oil level detector 136 is an optical fiber liquid level signal device, which includes a transmitting module and a receiving module installed on opposite sides of the oil tank 131. It transmits and receives light through optical fiber, and then uses the difference in light transmission between grease and air to detect whether the grease in the oil tank 131 has reached the lowest level that needs to be filled. Secondly, a signal processor is used to output a liquid level signal and transmit it to PLC135. PLC135 determines whether the oil pump 132 stops working based on the received signal. When the grease reaches the lowest level, the oil pump 132 stops working and the operator adds grease. PLC135 can also control the output flow and output time of the oil pump 132 based on the operator's data, so that PLC135 can control the oil pump 132 to deliver grease to sixteen lubrication points in a timely and quantitative manner, thereby realizing automatic filling of grease for the stacker, so that each lubrication point of the stacker is always stored with grease, thereby improving the service life of the load-bearing bearing 124, improving the operating accuracy of the stacker, and improving the accuracy of the stacker in handling goods.
[0037] Embodiment 2
[0038] Combination Figure 4 As shown, the second embodiment includes: the lower beam conveying device body 1 of the first embodiment; and a cargo-carrying assembly 2 arranged on the lower beam conveying device body 1, and the cargo-carrying assembly 2 moves along the conveying direction of the lower beam conveying device.
[0039] Specifically, the lower beam conveying device body 1 is laid on the warehouse floor according to the warehouse layout, and the bottom surface of the cargo assembly 2 is connected to the top surface of the lower beam conveying device body 1 by bolts, and it slides along the horizontal guide rail 11 together with the transverse slide 121. On the one hand, the transverse slide 121 and the horizontal guide rail 11 can provide a flat horizontal support for the cargo assembly 2, and on the other hand, the horizontal guide rail 11 limits the tipping and lateral movement of the transverse slide 121, thereby limiting the tipping and lateral movement of the cargo assembly 2, so that the cargo assembly 2 always moves along the same horizontal plane during the movement, so that the lower beam conveying device body 1 can stably transport the cargo assembly 2 to the specified position, so that the cargo assembly 2 can be accurately moved to the cargo position, and then transported to the specified position at a specified height.
[0040] Furthermore, the cargo assembly 2 includes: a mounting bracket 21 arranged on a side of the transverse slide 121 away from the horizontal guide rail 11, and the middle area of the mounting bracket 21 forms a U shape; a lifting guide rail 22 having a side connected to the opposite side of the mounting bracket 21, the length direction of the lifting guide rail 22 is the vertical direction, and the cross-section of the lifting guide rail 22 is rectangular; first lifting wheels 24 symmetrically arranged on the opposite sides of the lifting guide rail 22, the axis of the first lifting wheel 24 is the horizontal direction and parallel to the length direction of the horizontal guide rail 11, and the radial inner side surface of the first lifting wheel 24 is provided with a load-bearing bearing 124; a second lifting wheel 25 having a side that forms a rolling connection with the side of the mounting bracket 21 opposite to the lifting guide rail 22, the axis of the second lifting wheel 25 is the horizontal direction and perpendicular to the length direction of the horizontal guide rail 11, and the radial inner side surface of the second lifting wheel 25 is provided with a load-bearing bearing 124; and a cargo platform 23 moving along the lifting guide rail 22, and the first lifting wheel 24 and the second lifting wheel 25 are respectively provided on the two sides of the cargo platform 23 close to the lifting guide rail 22.
[0041] Specifically, the mounting bracket 21 is two parallel columns for mounting the lifting rail 22, and the bottom surface of the column is fixedly connected to the top surface of the transverse slide 121 by bolts, so that the column and the transverse slide 121 form a U-shaped area for placing the cargo platform 23. The cargo platform 23 is respectively connected to the side surfaces corresponding to the mounting bracket 21 by a first lifting wheel 24 and a second lifting wheel 25, so that the cargo platform 23 can be stably moved up and down along the lifting rail 22 by ropes.
[0042] Among them, the cross-section of the lifting guide rail 22 is rectangular, one side of which is fixedly connected to the mounting bracket 21, and its length direction is the same as the length direction of the mounting bracket 21, and the center lines of the length directions of both fall on the center plane of the transverse slide 121, so that the plane formed by the movement trajectory of the cargo platform 23 along the lifting guide rail 22 coincides with the center plane of the transverse slide 121, so that the pressure of the cargo platform 23 on the horizontal guide rail 11 is only a vertical downward pressure, avoiding the application of pressure on the side of the horizontal guide rail 11, resulting in different pressure conditions on the conveying support wheels 123 on both sides, and then causing different wear conditions on the conveying support wheels 123 on both sides, causing accelerated wear of the anti-tilt assembly 12 and reducing its service life.
[0043] Secondly, the rotating shaft of the first lifting wheel 24 is fixedly mounted on the cargo platform 23, and its axial direction is horizontal, and it is perpendicular to the length direction of the mounting bracket 21 and parallel to the length direction of the transverse sliding table 121. Its radial outer side surface forms rolling friction with the opposite side surface of the lifting guide rail 22 that is not in contact with the mounting bracket 21, so as to limit the movement of the cargo platform 23 in the length direction of the transverse sliding table 121 without affecting the movement of the cargo platform 23. The radial inner side surface of the first lifting wheel 24 is fixedly connected with a load-bearing bearing 124. The load-bearing bearing 124, which is always filled with grease, enables the first lifting wheel 24 to roll without jamming, so that the cargo platform 23 is accurate in the horizontal direction during movement, thereby improving the accuracy of its cargo handling; secondly, the second lifting wheel 25 The rotating shaft is also fixedly connected to the cargo platform 23, and its axial direction is horizontal, but its axial direction is perpendicular to the length direction of the mounting bracket 21 and the length direction of the transverse slide 121. Its radial outer side surface forms rolling friction with the side surface of the lifting guide rail 22 relative to the mounting bracket 21, so as to limit the movement of the cargo platform 23 along the length direction of the transverse slide 121 without affecting the movement of the cargo platform 23. The radial inner side surface of the second lifting wheel 25 is fixedly installed with a load-bearing bearing 124, so that the second lifting wheel 25 can roll without jamming and reduce friction, so that the first lifting wheel 24 and the second lifting wheel 25 can accurately limit the horizontal movement of the cargo platform 23, thereby ensuring the straightness of the motion trajectory of the cargo platform 23 when it moves vertically along the lifting guide rail 22.
[0044] Secondly, a total of eight first lifting wheels 24 and four second lifting wheels 25 are installed on the opposite sides of the cargo platform 23, with a total of twelve lubrication points. The oil pump 132 injects grease into the twelve lubrication points at the same time to ensure the lubrication effect of the first lifting wheels 24 and the second lifting wheels 25, further limit the moving trajectory of the cargo platform 23, and further improve the accuracy of the vertical movement of the cargo platform 23.
[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
