Description

Technical Field

[0001] The invention relates to the field of cargo racks, in particular to a cargo anti-tilt support rack. Background Art

[0002] With the booming development of the logistics and warehousing industries, efficient and safe transportation and storage of goods have become key elements in the supply chain of various industries. Whether it is the distribution of raw materials and parts in industrial production, or the circulation of finished goods in the commercial field, the handling and temporary storage of goods between different transportation carriers (such as trucks, ships, airplanes, etc.) and storage facilities (such as warehouse shelves, yards, etc.) is frequent and complicated.

[0003] At present, in the warehousing link, cargo racks are usually used to realize the classified storage of goods. Common cargo racks are mostly provided with multi-layer spaces distributed up and down, such as a combination structure of a cargo rack disclosed in a Chinese patent with publication number CN115886462A, which includes a plurality of T-shaped pillars, a plurality of T-shaped beams and a plurality of assembly parts. Each T-shaped pillar includes a T-shaped column, which has an inner side surface and an outer side surface facing each other, and a plurality of first assembly parts arranged in at least one row along the extension direction of the T-shaped column are provided on the inner side surface. Each T-shaped beam is suitable for being located between two T-shaped pillars, and each T-shaped beam has two assembly ends, and each assembly end is used to abut against the inner side surface of the corresponding T-shaped pillar. The two assembly ends of each T-shaped beam are respectively combined with at least one assembly part, and each assembly part has at least one second assembly part corresponding to the first assembly part, so as to assemble each T-shaped beam between the corresponding two T-shaped pillars.

[0004] Because the cargo racks provided by the above patents and other types of cargo racks are relatively high, although the environment is relatively stable, the loading and unloading, handling operations of the cargo and the structural characteristics of the storage facilities themselves may also lead to the risk of cargo tilting. For example, when using a forklift to place the cargo on the shelf, if the operation is improper or there are defects in the shelf structure design, the cargo may tilt during the placement process. Moreover, with the intensive use of storage space, the height of the shelves continues to increase. Once the cargo on the high-rise shelves tilts, the risk of falling and the harm caused will be more serious, which will not only damage the cargo itself, but also other cargo and storage equipment below, and even endanger the lives of on-site workers.

DETAILED DESCRIPTION

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0035] Example 1

[0036] like Figure 1-9As shown, in order to improve the stability of the cargo rack and reduce the probability of it tipping over under external force, this embodiment provides a new cargo support rack. The support rack includes a frame body 1 and two sets of support components 2, which are respectively arranged at both ends of the frame body 1 and can respond in time when the frame body 1 tilts, increase the resistance to the tilt of the frame body 1, and even prevent the frame body 1 from tilting.

[0037] Specifically, the frame 1 is configured as an upper and lower multi-layer structure, that is, it includes a plurality of layer boards, and goods can be directly stacked on the layer boards to achieve classified storage of goods.

[0038] Each supporting assembly 2 includes a supporting plate 21 , a first plate body 23 , a second plate body 24 , two telescopic cylinders 22 , two first guide rails 25 and two diagonal supporting plates 26 .

[0039] The support plate 21 is arranged along the length direction of the frame 1 and is arranged in a T-shaped structure. It is also arranged at the middle position of the bottom of the frame 1 to provide support for the installation of the first plate 23, the second plate 24 and the telescopic cylinder 22, and to facilitate the relative movement of the first plate 23 and the second plate 24.

[0040] In order to limit the movement of the first plate 23 and the second plate 24, the first plate 23 and the second plate 24 are both arranged along the width direction of the frame 1, and are arranged directly below the portion of the support plate 21 parallel to the width direction of the frame 1. A first guide groove 231 is arranged on the upper side of the first plate 23, and a second guide groove 241 is arranged on the upper side of the second plate 24. The first guide groove 231 and the second guide groove 241 are both arranged along the width direction of the frame 1. A pressing wheel 212 is arranged below the support plate 21, and the pressing wheel 212 is hingedly arranged at the bracket 213. A top plate 215 is vertically fixedly arranged on the top of the bracket 213, and a spring 214 is sleeved on the top plate 215. At the same time, the top plate 215 is movably connected to the support plate 21, so that under the action of the spring 214 in a compressed state, the pressing wheel 212 always has a downward trend. In addition, the width of the guide groove is greater than or equal to the thickness of the pressing wheel 212 , so the bottom of the pressing wheel 212 extends into the guide groove, and under the action of the pressing wheel 212 , the first plate 23 and the second plate 24 are restricted from moving along a preset direction.

[0041] In order to be able to control the movement of the first plate body 23 and the second plate body 24, two telescopic cylinders 22 (which can be set as electric cylinders) are distributed on both sides of the support plate 21, and one end is hingedly connected to the end of the support plate 21 (for example, hingedly connected through a central axis and a bearing), and the other end is hingedly connected to the ends of the first plate body 23 and the second plate body 24 that are away from each other. Therefore, under the operation of the telescopic cylinder 22, the first plate body 23 and the second plate body 24 are controlled to reciprocate along a preset direction, which provides convenience for controlling the inclination of the diagonal support plate 26 to support the frame 1.

[0042] In order to achieve the inclined placement of the diagonal support plate 26 and support the frame 1, the two diagonal support plates 26 are distributed on both sides of the frame 1, and the ends of the first plate 23 and the second plate 24 that are away from each other are respectively hingedly connected to the bottom of the two diagonal support plates 26. Therefore, when the first plate 23 and the second plate 24 move, the bottom of the diagonal support plate 26 can be controlled to move, forcing the diagonal support plate 26 to be at an inclined angle, thereby supporting the frame 1.

[0043] In order to facilitate the adjustment of the inclined support plate 26 to an inclined state, the first guide rail 25 is fixedly set on the frame 1, and the cross-section is set to a convex structure. A sleeve plate 261 is hingedly set on the top of the inclined support plate 26. The inner space of the sleeve plate 261 is the same as the cross-section of the first guide rail 25, and the sleeve plate 261 is sleeved on the first guide rail 25. Under the action of the sleeve plate 261, the inclined support plate 26 is movably connected to the first guide rail 25. Therefore, when the bottom of the inclined support plate 26 moves, the top of the inclined support plate 26 can be driven to rise and fall, which provides convenience for realizing that the inclined support plate 26 is in an inclined state.

[0044] In order to monitor the tilt state of the frame 1 in real time and provide convenience for timely starting the supporting component 2, an inclinometer 31 is arranged on the top of a first guide rail 25, and a control box 3 is also arranged below the frame 1, and a controller (such as a PLC), a relay, a contactor, a frequency converter, a switching power supply, etc. are arranged in the control box 3. The inclinometer 31 and the telescopic cylinder 22 are both connected to the control box 3, and the connection technology has been disclosed. For example, if the inclinometer outputs an analog signal (such as a voltage signal or a current signal), a shielded cable can be used to connect its signal output end to the analog input port of the controller in the control box. For a DC electric telescopic cylinder, its power input end can be connected to the switching power supply output end in the control box through a cable. In order to control the telescopic action of the telescopic cylinder, it is necessary to control the on and off of its power supply through a relay or a contactor. The output end of the relay or contactor is connected to the power input line of the telescopic cylinder. When the controller (such as a PLC) sends a control signal, the coil of the relay or contactor is driven to close or disconnect its contacts, thereby realizing the control of the power supply of the telescopic cylinder. For example, when the controller outputs a high-level signal to the relay coil, the normally open contacts of the relay close, connecting power to the telescopic cylinder, causing it to begin to extend or retract.

[0045] Because the inclinometer 31 mainly works based on the principle of gravity or acceleration. Taking the electronic inclinometer based on the accelerometer as an example, the acceleration sensor inside it can sense the changes in the components of gravity acceleration in different directions in real time. When the object tilts, the component of gravity acceleration on the sensitive axis of the sensor will change immediately, and the sensor converts this change in physical quantity into an electrical signal. Through the built-in signal processing circuit, after a series of operations such as amplification, filtering, analog-to-digital conversion, etc., the electrical signal can be output in real time with a numerical value corresponding to the tilt angle. Therefore, the tilt angle of the frame 1 can be monitored in real time by the inclinometer 31. Once the tilt angle exceeds the set threshold, such as 5 degrees, the telescopic cylinder 22 can be controlled to work to control the first plate 23 or the second plate 24 to work, so that it protrudes from the frame 1, and the diagonal support plate 26 is in a tilted state, generating resistance of corresponding size and direction to correct the tilt of the support frame, so that the goods are always kept in a relatively stable state.

[0046] In order to stably install the inclinometer 31 on the first guide rail 25, a fixing plate 32 is provided on the back side of the inclinometer 31 via bolts, and a plug-in plate 33 is fixedly provided on the side of the fixing plate 32 away from the inclinometer 31. The plug-in plate 33 is inserted into the top of the first guide rail 25, so that the inclinometer 31 can be stably installed on the top of the first guide rail 25.

[0047] In order to ensure that the top plate 215 is stably connected to the support plate 21, a plurality of through holes 211 are provided on the portion of the support plate 21 parallel to the width direction of the frame body 1. The plurality of through holes 211 are evenly distributed along the width direction of the frame body 1. The top plate 215 passes through a certain through hole 211, and the top of the spring 214 contacts the lower side of the support plate 21, and the spring 214 is in a compressed state.

[0048] In order to prevent the existence of the first plate body 23 and the second plate body 24 from affecting the movement of each other, a snap groove 232 is provided on the bottom surface of the first plate body 23. The snap groove 232 is provided along the length direction of the first plate body 23, and the end is provided as an opening. The cross-section of the second plate body 24 is the same as the cross-section of the snap groove 232, and the end is inserted into the snap groove 232, so that the first plate body 23 and the second plate body 24 are movably plugged in and connected, thereby providing support for the movement of the first plate body 23 and the second plate body 24.

[0049] Example 2

[0050] like Figure 11-12As shown, on the basis of Example 1, in order to prevent the movement of goods when the frame 1 is tilted, a second guide rail 4 is provided on the edge of each layer of the frame 1, and a baffle 5 is provided on the side of the second guide rail 4. The number can be determined according to actual conditions. A sleeve 51 is fixedly provided at the end of the baffle 5. The sleeve 51 is connected to the connecting shaft 52 through a bearing. The connecting shaft 52 is fixedly provided on the connecting plate 53. The connecting plate 53 is provided with a connecting groove 54. The second guide rail 4 is provided through the connecting groove 54, that is, the connecting plate 53 is movably connected to the second guide rail 4, which provides convenience for adjusting the position and number of the baffle 5 according to needs.

[0051] In addition, a boss 55 is fixedly provided on the outer surface of the sleeve 51, and a side plate 57 is provided on the side. A limiting bolt 59 is threadedly penetrated through the side plate 57. A plurality of slots 41 are provided on the second guide rail 4. The end of the limiting bolt 59 is inserted into a slot 41 to limit the baffle 5 to be stably placed relative to the frame 1.

[0052] At the same time, a groove 56 is provided at the end of the side panel 57, and a counterweight ball 58 is suspended below. The central angle of the groove 56 is greater than 180°, and the convex column 55 passes through the groove 56 to realize the movable connection between the side panel 57 and the sleeve 51. At the same time, when the frame 1 is tilted, the side panel 57 is driven by the counterweight ball 58 to move relative to the sleeve 51, so that the limit bolt 59 is disengaged from the slot 41, the restriction of the baffle 5 is released, and the baffle 5 is in a vertical state to facilitate the movement of goods.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
