Description

Technical Field

[0001] This invention belongs to the field of conveying equipment technology, and specifically relates to an active protection unloading platform. Background Technology

[0002] Unloading platforms are common material handling platforms widely used in various fields. They typically consist of a suspended base for placing materials. For example, in logistics, the suspended base facilitates docking with truck beds, allowing materials to be moved horizontally from the truck bed to the base. In construction, the base is installed on high-rise buildings, and suspended equipment places materials on it, allowing construction workers to transfer materials to higher floors. Because the base is suspended, and materials and personnel must stand on it, improving the safety of unloading platforms is a crucial technical challenge that needs to be addressed. Summary of the Invention

[0003] The purpose of this invention is to provide an active protection unloading platform, which has the advantage of high safety.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: This application provides an active protective unloading platform, including a base plate. Along the width direction of the base plate, the base plate includes two opposing baffles. Each baffle is equipped with a protective assembly, which includes a deformation chain, a driving component, and a lifting component. The deformation chain includes multiple protective units connected in sequence. One end of each protective unit has an insertion hole, and the other end has an insertion part. Between two adjacent protective units, the insertion part of one unit is inserted into the insertion hole of the other unit. The insertion part and the insertion hole are clearance-fitted, and the inner walls of the insertion part and the insertion hole are rotatably connected. The driving component includes a moving part, a limiting part, and a first elastic member. The moving part is movably connected to the baffle along the length direction of the baffle. The first elastic member connects the moving part and the limiting part. The limiting part is movably connected to the baffle along the width direction of the baffle and abuts against the moving part. One end of the deformation chain is rotatably connected to the baffle, and the other end is rotatably connected to the moving part. The lifting component is disposed on the baffle and is used to lift the deformation chain.

[0005] In some embodiments, a first shielding net is provided between the deformation chain and the baffle.

[0006] In some embodiments, the lifting component includes a sliding sleeve, a sliding portion, a second elastic member, and a pin portion. The sliding sleeve is disposed on the baffle, and the sliding portion is movably connected to the sliding sleeve along the height direction of the baffle, and the sliding portion abuts against the deformation chain. The second elastic member connects the sliding sleeve and the sliding portion, and the pin portion is movably connected to the sliding sleeve, with the movement direction of the pin portion perpendicular to the height direction of the baffle. The sliding portion is provided with a pin hole, and the pin portion is inserted into the pin hole.

[0007] In some embodiments, the end of the protective unit with the insertion hole is truncated cone-shaped.

[0008] In some embodiments, a shielding assembly is further included, comprising a sleeve, a second shielding net, and an ejector component. Two sleeves are provided corresponding to the deformation chain, with the sleeves fitted onto the deformation chain and positioned at the end of the deformation chain away from the moving part. The second shielding net is connected to a base plate, and the sleeve is connected to the second shielding net via a connecting cable. The ejector component drives the sleeve to move towards the end of the deformation chain closer to the moving part.

[0009] In some embodiments, the ejection component includes an electromagnetic acceleration channel and a launch head, the launch head being inserted into the electromagnetic acceleration channel and connected to the sleeve via a connecting cable.

[0010] In some embodiments, the ejection component is disposed on opposite sides of the two baffles.

[0011] In some embodiments, the sleeve includes two semi-rings connected by a third elastic member.

[0012] In some embodiments, the shielding assembly further includes a flexible support portion, a second shielding net is connected to the flexible support portion, and the sleeve is connected to the flexible support portion via a connecting cable.

[0013] In some embodiments, along the width direction of the base plate, two columns are provided on the base plate corresponding to the two baffles. The interior of the columns is hollow, and the opposite sides of the two columns are respectively provided with notches and slots communicating with the interior of the columns. The second shielding net is provided in the columns through the notches and slots on both sides along the width direction.

[0014] The present invention has the following beneficial effects:

[0015] 1. When the base plate becomes loose, the limiting part moves away, and the moving part causes the deformation chain to bend. When the deformation chain bends to the limit position, it can no longer bend, thus forming a bent structure. The deformation chain and the baffle increase the shielding area, enabling the deformation chain to play a protective role and reducing the risk of materials or personnel falling from the base plate.

[0016] 2. The operation of the limiting part and the lifting part can be controlled by the processor, so that the device can actively protect itself. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0026] In the description of this invention, it should be understood that the terms "upper," "lower," "inner," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0027] See Figure 1 , Figure 2 and Figure 3This application provides an active protection unloading platform, including a base plate 1. Along the width direction of the base plate 1, the base plate 1 includes two opposing baffles 2. The baffles 2 are provided with protective components 3. The protective components 3 include a deformation chain 31, a driving component 33, and a lifting component 32. The deformation chain 31 includes a plurality of protective units 311 connected in sequence. One end of the protective unit 311 is provided with an insertion hole 312, and the other end is provided with an insertion part 313. Between two adjacent protective units 311, the insertion part 313 of one is inserted into the insertion hole 312 of the other. The insertion part 313 and the insertion hole 312 are clearance-fitted, and the inner wall of the insertion part 313 and the insertion hole 312 are rotatably connected. The driving component 33 includes a moving part 331, a limiting part 332, and a first elastic member 333. The moving part 331 is movably connected to the baffle 2 along its length. The first elastic member 333 connects the moving part 331 and the limiting part 332. The limiting part 332 is movably connected to the baffle 2 along its width and abuts against the moving part 331. One end of the deformation chain 31 is rotatably connected to the baffle 2, and the other end is rotatably connected to the moving part 331. A lifting component 32 is disposed on the baffle 2 and is used to lift the deformation chain 31.

[0028] The width direction of base plate 1 can be Figure 1 In the direction indicated by the X-axis, the width direction of baffle 2 can be parallel to the width direction of base plate 1. The length direction of baffle 2 can be... Figure 1 In the direction indicated by the Y-axis, the length direction of the baffle 2 can be parallel to the length direction of the base plate 1.

[0029] The base plate 1 is used to place materials. The fixing structure of the base plate 1 on other building structures is known to those skilled in the art. The technical solution of this application does not improve the fixing structure of the base plate 1, so it will not be described in detail.

[0030] The inner walls of the insertion part 313 and the insertion hole 312 are rotatably connected, so that two adjacent protective units 311 can rotate relative to each other.

[0031] The insertion part 313 and the insertion hole 312 are fitted with a clearance, so that the two adjacent protective units 311 can only rotate within the range defined by the insertion hole 312. This allows the deformation chain 31 to form a rigid structure when it is bent to its limit.

[0032] For example, the insertion part 313 may be provided with a rotating shaft, and the inner wall of the insertion hole 312 may be provided with a shaft hole. The rotating shaft of the insertion part 313 is inserted into the shaft hole, so that the insertion part 313 can rotate relative to the inner wall of the insertion hole 312.

[0033] Since multiple protective units 311 are connected in sequence, that is, all protective units 311 face the same direction, the protective unit 311 at the head of the deformation chain 31 does not need to be provided with an insertion part 313, and the protective unit 311 at the tail of the deformation chain 31 does not need to be provided with an insertion hole 312.

[0034] The baffle 2 may be provided with a sliding groove, and the moving part 331 is movably connected to the baffle 2 through the sliding groove.

[0035] The first elastic element 333 can be a spring. In the initial state, the moving part 331 can be disposed on one side of the baffle 2. The elastic restoring force of the first elastic element 333 is used to drive the moving part 331 to move to the other side of the baffle 2.

[0036] The limiting part 332 is used to limit the moving part 331. That is, when the limiting part 332 abuts against the moving part 331, the moving part 331 cannot move to the other side of the baffle 2.

[0037] When the limiting part 332 moves so that the limiting part 332 no longer abuts against the moving part 331, the moving part 331 can move. The moving part 331 drives the deformation chain 31 to move from one end connected to the moving part 331 to the end rotatably connected to the baffle 2, so that the deformation chain 31 can bend.

[0038] In this embodiment, the limiting part 332 can be moved by an electric cylinder, that is, the movable end of the electric cylinder is connected to the limiting part 332, so that the moving end can drive the limiting part 332 to move. The structure and working principle of the electric cylinder are well known to those skilled in the art, and will not be described in detail here.

[0039] Initially, the deformation chain 31 can be in a straight state. At this time, the moving part 331 cannot push the deformation chain 31 to bend, and the deformation chain 31 will not excessively block the bottom plate 1, which facilitates material transfer. When the lifting part 32 lifts the deformation chain 31, the deformation chain 31 can bend upward, thereby allowing the moving part 331 to drive the end of the deformation chain 31 connected to the moving part 331 to move towards the end rotatably connected to the baffle 2.

[0040] In this embodiment, the limiting part 332 and the lifting part 32 can be driven by a processor. That is, the electric cylinder driving the limiting part 332 and the lifting part 32 are electrically connected to the processor, allowing the processor to control their operation. The base plate 1 can also be equipped with a detection component to determine its state. This detection component is electrically connected to the processor. For example, the detection component could be an accelerometer, which can detect movement of the base plate 1.

[0041] The specific model of the processor, the specific circuits, control codes, and control principles that are electrically connected to the electric cylinder, lifting component 32, and detection component are well known to those skilled in the art and will not be elaborated here.

[0042] When the base plate 1 becomes loose, for example, if the connection between the base plate 1 and the building structure is damaged, causing the base plate 1 to become loose, the detection component determines the state of the base plate 1. Then, the processor controls the lifting component 32 to lift the deformation chain 31, the limiting part 332 moves away, and the moving part 331 causes the deformation chain 31 to bend. When the deformation chain 31 bends to its limit position, the deformation chain 31 can no longer bend, so that the deformation chain 31 forms a bent structure. The deformation chain 31 and the baffle 2 work together to increase the shielding area, so that the deformation chain 31 can play a protective role and reduce the risk of materials or personnel falling from the base plate 1.

[0043] Furthermore, by reasonably setting the number of protective units 311 and the starting position of the moving part 331 relative to the baffle 2, the shielding area of ​​the deformation chain 31 can be flexibly adjusted.

[0044] In this embodiment, the deformation chain 31 is rotatably connected to one side of the baffle 2 and can be close to the suspended side of the base plate 1. The side of the deformation chain 31 close to the moving part 331 can be close to the base plate 1 and connected to one side of the building structure.

[0045] In some embodiments, a first shielding net is provided between the deformation chain 31 and the baffle 2.

[0046] The first shielding net is not shown in the figure. The specific size of the first shielding net can be set as needed, as long as the deformation chain 31 can bend and expand the first shielding net.

[0047] When the deformation chain 31 bends, it can expand the first shielding net, thereby increasing the shielding area and improving the protective effect of the deformation chain 31.

[0048] See Figure 1 and Figure 6 In some embodiments, the lifting component 32 includes a sliding sleeve 321, a sliding portion 322, a second elastic element 324, and a pin portion 323. The sliding sleeve 321 is disposed on the baffle 2, and the sliding portion 322 is movably connected to the sliding sleeve 321 along the height direction of the baffle 2, and the sliding portion 322 abuts against the deformation chain 31. The second elastic element 324 connects the sliding sleeve 321 and the sliding portion 322, and the pin portion 323 is movably connected to the sliding sleeve 321. The moving direction of the pin portion 323 is perpendicular to the height direction of the baffle 2, and the sliding portion 322 is provided with a pin hole, into which the pin portion 323 is inserted.

[0049] The height direction of baffle 2 can be Figure 1 The direction indicated by the Z-axis.

[0050] The sliding part 322 is inserted into the sliding sleeve 321, so that the sliding part 322 can move along the height direction of the baffle 2.

[0051] The second elastic element 324 can be a spring. The second elastic element 324 can be used to drive the sliding part 322 to move, so that the sliding part 322 can lift the deformation chain 31, thereby allowing the deformation chain 31 to bend initially.

[0052] The pin 323 can also be driven by an electric cylinder. The pin 323 can be moved by the electric cylinder, meaning the movable end of the electric cylinder is connected to the pin 323, so that the movement of the movable end can drive the pin 323 to move. The structure and working principle of the electric cylinder are well known to those skilled in the art and will not be described in detail here. Similarly, the electric cylinder that drives the pin 323 can also be controlled by a processor.

[0053] When the pin 323 is inserted into the pin hole, the sliding part 322 cannot move relative to the sliding sleeve 321. When the pin 323 is removed from the pin hole, under the action of the elastic restoring force of the second elastic element 324, the sliding part 322 moves along the height direction of the baffle 2, lifting the deformation chain 31.

[0054] See Figure 2 In some embodiments, the end of the protective unit 311 with the insertion hole 312 is truncated cone-shaped.

[0055] The end of the protective unit 311 with the insertion hole 312 is truncated cone-shaped, which increases the wall thickness of the side of the protective unit 311 with the insertion hole 312, thereby increasing the connection strength between two adjacent protective units 311.

[0056] See Figure 1 and Figure 4 In some embodiments, a shielding component 4 is also included, comprising a sleeve 41, a second shielding net 43, and an ejector component 42. Two sleeves 41 are configured corresponding to the deformation chain 31, with each sleeve 41 fitted onto the deformation chain 31 and positioned at the end of the deformation chain 31 furthest from the moving part 331. The second shielding net 43 is connected to the base plate 1, and the sleeve 41 is connected to the second shielding net 43 via a connecting cable. The ejector component 42 drives the sleeve 41 to move towards the end of the deformation chain 31 closer to the moving part 331.

[0057] The sleeve 41 is fitted onto the deformation chain 31, so that the sleeve 41 can move along the deformation chain 31.

[0058] The second shielding net 43 can be set at the end of the deformation chain 31 away from the moving part 331.

[0059] The second shielding net 43 is connected to the sleeve 41 by a connecting cable, so that when the sleeve 41 moves along the deformation chain 31, the sleeve 41 can drive the second shielding net 43 to move towards the end of the deformation chain 31 closer to the moving part 331, so that the second shielding net 43 can play a shielding role and further increase the protective effect of the device.

[0060] The sleeve 41 can be driven to move by the ejector component 42 after the deformation chain 31 bends. This allows the second shielding net 43 to move towards the end of the deformation chain 31 near the moving part 331. At the same time, the second shielding net 43 moves upward in the height direction of the baffle 2 and then moves downward. This increases the shielding area of ​​the second shielding net 43. On the other hand, even if materials or personnel tend to fall out of the base plate 1 or jump relative to the base plate 1, the second shielding net 43 can press the materials or personnel against the base plate 1, thus increasing the protective effect of the second shielding net 43.

[0061] The insertion part 313 of the protective unit 311 is inserted into the insertion hole 312. When the deformation chain 31 is in a bent state, a recess 314 can be formed between two adjacent protective units 311. When the sleeve 41 is in a position close to the moving part 331 of the deformation chain 31, when the material or personnel hit the second shielding net 43, the second shielding net 43 is subjected to a force along the length direction of the baffle 2. This allows the second shielding net 43 to drive the sleeve 41 to be inserted into the recess 314 between two adjacent protective units 311. The sleeve 41 cannot move relative to the deformation chain 31, thereby reducing the risk that the sleeve 41 will move away from the moving part 331 of the deformation chain 31 and the second shielding net 43 will be opened. The bending structure of the deformation chain 31 causes the opening of the recess 314 to gradually rotate from the highest point formed after the deformation chain 31 bends to the end of the deformation chain 31 near the moving part 331. At the highest point, the opening of the recess 314 is almost facing upwards, and when the deformation chain 31 moves to the end of the moving part 331, the opening of the recess 314 gradually rotates to face the moving part 331. This makes the recess 314 have a better limiting effect on the sleeve 41 the closer the sleeve 41 is to the moving part 331, and thus makes the protective effect of this device better.

[0062] In an embodiment where one end of the insertion hole 312 in the protective unit 311 is truncated cone-shaped, the truncated cone structure of the protective unit 311 can guide the sleeve 41, preventing the sleeve 41 from getting stuck in the recess 314 between two adjacent protective units 311 during its movement along the deformation chain 31 towards the moving part 331. Furthermore, once the sleeve 41 is in place, the larger diameter side of the truncated cone structure can hinder the sleeve 41, reducing the risk that the sleeve 41 will cause the second shielding net 43 to reset towards the side of the deformation chain 31 away from the moving part 331.

[0063] See Figure 4In some embodiments, the ejection component 42 includes an electromagnetic acceleration channel 422 and a launch head 421, the launch head 421 being inserted into the electromagnetic acceleration channel 422 and connected to the sleeve body 41 by a connecting cable.

[0064] The structure and working principle of the electromagnetic acceleration channel 422 are well known to those skilled in the art. In general, the transmitter 421 is made of metal. The transmitter 421 is placed in the electromagnetic acceleration channel 422. When the electromagnetic acceleration channel 422 is energized, the transmitter 421 is launched under the action of the magnetic field generated by the electromagnetic acceleration channel 422, which in turn enables the transmitter 421 to drive the sleeve 41 to move.

[0065] The operation of the electromagnetic acceleration channel 422 can also be controlled by the processor, so that the operation of the shielding component 4 can be actively controlled by the processor.

[0066] In some embodiments, the ejection component 42 is disposed on opposite sides of the two baffles 2.

[0067] Although in the illustrated embodiment the ejection component 42 is disposed on the opposite side of the baffle 2, as a parallel embodiment, the ejection component 42 may be disposed on the opposite sides of the two baffles 2.

[0068] By placing the ejection component 42 on opposite sides of the two baffles 2, the risk of the launch head 421 colliding with personnel standing on the base plate 1 during launch is reduced, thus improving the safety of the device.

[0069] Furthermore, this arrangement allows the connection point between the connecting cable between the transmitter head 421 and the sleeve 41 and the sleeve 41 to be located on opposite sides of the two baffles 2. Consequently, the sleeve 41 can pull the second shielding net 43 to move towards opposite sides of the two baffles 2 via the connecting cable between the sleeve 41 and the second shielding net 43, allowing the second shielding net 43 to be opened on both sides in the width direction of the base plate 1, thereby increasing the protective effect of the second shielding net 43.

[0070] See Figure 5 In some embodiments, the sleeve 41 includes two semi-rings 411 connected by a third elastic member 412.

[0071] The third elastic element 412 can be a spring.

[0072] The two semi-rings 411 are connected by a third elastic element 412, allowing the two semi-rings 411 to separate from each other. This allows the sleeve 41 to pass through the frustoconical end of the protective unit 311. After the sleeve 41 passes through the frustoconical end of the protective unit 311, the two semi-rings 411 close together, increasing the obstruction effect of the frustoconical end of the protective unit 311 on the sleeve 41 and reducing the risk of the second shielding net 43 resetting.

[0073] See Figure 5 In some embodiments, the shielding component 4 further includes a flexible support portion 44, a second shielding net 43 connected to the flexible support portion 44, and a sleeve 41 connected to the flexible support portion 44 via a connecting cable.

[0074] The flexible support part 44 is used to open the second shielding net 43, so that when the sleeve 41 pulls the second shielding net 43 to move, the second shielding net 43 can be in an open state, which increases the protective effect of the second shielding net 43.

[0075] The flexible material of the flexible support part 44 reduces the risk of damage caused by collision between the flexible support part 44 and the baffle 2 or the deformation chain 31 during the movement of the sleeve 41. For example, the flexible support part 44 can be made of rubber, which can both expand the second shielding net 43 and reduce the risk of damage caused by collision between the flexible support part 44 and the baffle 2 or the deformation chain 31.

[0076] See Figure 1 and Figure 7 In some embodiments, along the width direction of the base plate 1, the base plate 1 is provided with two columns 5 corresponding to the two baffles 2. The interior of the columns 5 is hollow, and the opposite sides of the two columns 5 are respectively provided with notches 51 that communicate with the interior of the columns 5. The second shielding net 43 is provided in the columns 5 through the notches 51 on both sides along the width direction.

[0077] The interior of the column 5 can accommodate the two sides of the second shielding net 43 along the width direction of the base plate 1, which allows the area of ​​the second shielding net 43 to be set larger, increasing the protective effect.

[0078] Furthermore, the notch 51 allows the second shielding net 43 to be stored in a wave-like layer within the notch 51, enabling the second shielding net 43 to be smoothly pulled and moved by the sleeve 41.

[0079] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
