For example, during port operation transportation, the goods need to be sent from the warehouse to the port, which is usually accomplished by transportation by car and by road, but such transportation has the following disadvantages:

(1) the phenomena of random goods picking and centralized goods discharging are frequent, the loading and unloading equipment runs in an overload mode during the peak period of goods discharging, and the road of a factory is seriously blocked;

(2) the market of the automobile carriers is scattered, the transportation capacity resources are difficult to integrate and schedule effectively, and the transportation cost is high;

(3) the transportation danger of individual goods is large, and serious potential safety hazard exists for public transportation. For example, common coil steel and tube steel have special shapes, and if abnormal conditions occur in the process of automobile transportation, such as emergency braking or emergency avoidance and sharp turning, the common coil steel and tube steel are easy to fall off and thrown out of a freight transportation device due to small friction force in a rolling mode, and even accidents of bridge collapse occur, so that immeasurable casualties are caused.

(4) Heavy trucks produce severe environmental pollution such as carbon emissions, noise, dust, etc. during transportation. Taking carbon emissions as an example, if the annual capacity is 300 ten thousand tons, the carbon emission of the annual capacity is about 3494.4 tons/year, calculated according to the carbon emission factor of 1120g/km, which is the average of 40 ton trucks.

To make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the following examples and drawings, and the exemplary embodiments and descriptions thereof of the present invention are only used for explaining the present invention, and are not intended as limitations of the present invention.

As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural, unless the context clearly dictates otherwise. Meanwhile, "left" and "right" in the present application are only relative orientation concepts, and do not refer to absolute directions.

In some embodiments, a cargo transportation system is shown in fig. 1. The to-be-transported member 1000 can be transported from the material flow starting point a at the left end to the material flow end point C at the right end. The object 1000 to be transported is preferably a steel coil or other material with cylindrical or spherical shape capable of rolling and conveying the object.

As shown in fig. 1, a corresponding number of working sections D are configured to connect the logistics starting point a and the logistics ending point C according to the straight-line distance between the two, and of course, if the transportation is short, only one working section D may be provided, which is not described in detail herein. As shown in fig. 1, a relay station B is further provided between adjacent working sections D, and the relay station B can stop the object 1000 to be transported halfway, and is also convenient for station maintenance and repair.

As shown in fig. 2, the working section D includes a chute section D1 and a lifting section D4 arranged from left to right, and the member to be transported 1000 can perform directional movement in the working section D. The chute section D1 is arranged high at the left and low at the right. The sliding section D1 is arranged in a high-right-low manner, so that the to-be-transported object 1000 can fall from left to right and from top to bottom along the arrangement path of the sliding section D1 under the action of gravity after being sent from the material flow starting point A to enter the working section D, so that the gravitational potential energy of the object at the left end of the sliding section D1 is converted into the kinetic energy reaching the right end of the sliding section D1, and the initial speed V0 is obtained; to achieve this, the chute section D1 is preferably constructed as an inclined slope, and may be an arc or a similar arc, which enables the article 1000 to fall thereon and obtain the initial velocity V0.

Lifting device 6 is arranged above lifting section D4, and upper and lower limiting areas are arranged from top to bottom, and lifting device 6 can be arranged in relay station B for convenient maintenance. The directional movement in the working section D includes: after the piece to be transported obtains the initial speed V0 at the sliding section D1, the piece to be transported continues to advance to the lower limit area of the lifting section D4 and is lifted to the upper limit area through the lifting device 6, so that the piece to be transported 1000 supplements the gravitational potential energy again.

Thus, the piece to be transported 1000 enters the working section D from the logistics starting point a, freely falls in the sliding section D1 to convert gravitational potential energy into kinetic energy and obtain an initial speed V0, then reaches the lifting section D4 by virtue of the initial speed V0, is lifted to the upper limiting area under the action of the lifting device 6, is replenished with gravitational potential energy to enter the next working section D, continuously circulates in a mode of 'entering the working section D → the sliding section D1 is accelerated to the initial speed V0 → reaching the lifting section D4 → the lifting section D4 is charged → entering the next working section D', and finally reaches the logistics end point C, so that the cargo transportation is realized. This application the device, be particularly useful for coil steel class goods, the cylindrical structure that it has can slide and obtain great initial velocity V0 at the smooth of section D1 that puts of swift current with rolling mode, adopts this application device to transport coil steel class goods simultaneously, owing to go on specific route, can not appear blocking up the condition like traditional vapour transport mode, also can avoid the situation of emergency brake and urgent turn, and then stop the potential safety hazard. Meanwhile, the lifting section D4 is preferably arranged in a vertical orientation mode so as to save space; the lifting device 6 is preferably beneficial to realizing a lifter structure for lifting cargos, an upper limiting area is arranged at the top of the lifting section D4, and a lower limiting area is arranged at the bottom of the lifting section D4; the lifting section D4 may also be set to be a slope with a lower left and a higher right, an arc-like or circular arc structure, and the lifting device 6 may be set to be any structure such as a booster, a transmission belt, etc. which can make the member to be transported 1000 supplement energy at the lifting section D4 according to the structure of the lifting section D4, which will not be described in detail herein.

Further, the working segment D also includes a buffer segment D2 shown in fig. 2. The buffer section D2 is located between the chute section D1 and the lifting section D4, and the directional movement further comprises: the buffer section D2 decelerates the to-be-transported member 1000 to the set speed V1. Therefore, the speed of the to-be-transported part 1000 is controlled, and the to-be-transported part enters the lifting section D4 at a controllable speed, so that buffering, shock absorption and energy dissipation are realized, and a large impact load generated in the subsequent process due to the fact that the speed is too high is prevented. To achieve this effect, the buffer section D2 may be a reverse slope with a lower left and a higher right or a similar arc road section, so that the to-be-transported object 1000 is decelerated by friction or the like after reaching the buffer section D2 and decelerated to the set speed V1 when leaving the buffer section D2. In the preferred mode of the present application, a damper device 2 is provided in the buffer section D2 as shown in fig. 2; the damping device 2 can generate resistance opposite to the moving direction of the to-be-transported member 1000, so that the to-be-transported member 1000 is decelerated to the set speed V1. It should be noted that, as a variation of the present application, the buffering section D2 is eliminated, and a plurality of damping devices 2 are arranged in the chute section D1 at intervals, for example, the chute section D1 is a slope structure, and the to-be-transported object 1000 is accelerated continuously in the chute section D1 by gravity, is accelerated to a certain extent, is decelerated by the damping devices 2, and is repeated so that the to-be-transported object 1000 leaving the chute section D1 can be controlled in speed.

In some embodiments, considering that the cargo has different specifications and weights during the transportation process of the cargo by using the device of the present application, the cargo has different initial velocity V0 and different momentum after the cargo is accelerated in the chute section D1, in order to make the resistance generated by the damping device 2 adaptable to the cargo with different specifications and weights, so as to better decelerate the cargo to the set velocity V1 in the buffer section D2, the velocity control is realized. As shown in fig. 3, the buffer segment D2 is divided into a velocity measurement segment D21 and a damping speed regulation segment D22 which are manufactured left and right; the damping device 2 is arranged at the damping speed regulating section D2.

The to-be-transported member 1000 can be collected with the initial information Y at the speed measurement section D21. The damping device 2 can adjust the damping magnitude based on the initial information Y to decelerate the transport object 1000. The damping device 2 can be a hydraulic thrust device opposite to the moving direction of the piece to be transported 1000, and the speed reduction of different pieces to be transported 1000 is realized by generating hydraulic forces with different magnitudes; the device can also be an electromagnetic device, and the speed reduction of different pieces to be transported 1000 is realized by generating electromagnetic force with different sizes; or a slope resistance device, and the speed reduction of different pieces to be transported 1000 is realized by generating a slope with the opposite moving direction and different slopes of the pieces to be transported 1000. The preferred setting mode of this application is that setting damping device 2 and being constituteed by a plurality of damping module 21, a plurality of damping module 21 concatenates in proper order along waiting to transport 1000 direction of motion, and every damping module 21 can both produce corresponding resistance and treat that transport 1000 slows down. The initial information Y includes the initial velocity V0 and the weight W of the to-be-transported piece 1000 collected as shown in fig. 21, and the corresponding specification of the to-be-transported piece 1000 may be increased. The damping device 2 can determine the number of the damping modules 21 according to the collected initial information Y, so as to determine the generated resistance, so as to achieve the accurate control of the speed of the member to be transported 1000.

In order to make the control process more intelligent, as shown in fig. 22, each operating segment D is provided with a control unit 100, and each speed measuring segment D21 is also provided with an information collector 8. The information collector 8 is used for collecting initial information Y, and here the information collector 8 includes a speed sensor capable of collecting initial speed V0 and a gravity sensor capable of collecting weight W, and an infrared sensor can be added to collect specifications of the to-be-transported member 1000. The damping device 2 and the information collector 8 are electrically connected to the control unit 100, respectively. Thus, the information collector 8 sends the collected initial information Y to the control unit 100, and the control unit 100 can control the damping device 2 based on the received initial information Y, so that the damping device 2 determines the number of the damping modules 21 to be operated, and then controls the size of the corresponding resistance to be generated, thereby achieving the purpose of accurately reducing the speed of the to-be-transported object 1000. Similarly, the damping module 21 can also be electromagnetic, ramp resistance, friction, or a combination thereof to realize the speed reduction.

The application also provides a preferable structure of the damping module 21, and as shown in fig. 7 to 13, the damping device 2 comprises a damping base 210, a damping block 211, a damping lifter 212, a damping support block 213 and a damping restorer 214. The damping base body 210 is integrally in a cuboid structure, is embedded on the bottom surface of the damping speed regulation section D22 and is provided with a damping inner cavity; the damping cavity opening is located on the top surface of the damping base 210. The damping repositor 214 is of a flexible and telescopic structure, one end of the damping repositor is hinged to the lower right corner of the damping inner cavity, and the other end of the damping repositor is hinged to the damping block 211. The damping lifter 212 is arranged on the left side of the bottom of the damping inner cavity. The damping supporting blocks 213 are arranged on the top of the damping inner cavity and symmetrically arranged on two side surfaces of the damping inner cavity adjacent to the damping restorer 214. A left ejection opening is formed between the left end of the damping supporting block 213 and the left side surface of the damping inner cavity, and a right landing opening is formed between the right end of the damping supporting block 213 and the right side surface of the damping inner cavity.

Fig. 8 to 12 are schematic diagrams showing the state of the damping module 21 gradually changing in the process that the to-be-transported object 1000 moves from left to right on the top surface of the damping module 21. As shown in fig. 8 to 10, when the damping module 21 operates, the damping lifter 212 lifts the damping block 211 out of the damping cavity from the left ejection opening, and at this time, the to-be-transported member 1000 moves to the right to contact with the damping block 211. The damping mass 211 then moves with the article 1000 to be transported away from the left ejection opening and over the damping brace 213. During the rightward movement in fig. 10 and fig. 11, the object to be transported 1000 will continuously receive the sliding friction resistance given to the damping block 211 by the top surface of the damping module 21, and the elastic deformation resistance given to the damping block 211 by the continuous contraction of the damping repositor 214, thereby realizing the deceleration of the object to be transported 1000. As shown in fig. 12, when the damping mass 211 moves to a position right above the right landing port, it freely falls by gravity, and thus is released from contact with the object 1000 to be transported. The damping repositor 214 restores the elastic deformation, so that the damping block 211 rebounds to the position shown in fig. 8 to be repositioned; the to-be-transported object 1000 continues to move rightward, and reaches the next damping module 21, and the speed reduction process is repeated, so that the damping device 2 controls the speed of the to-be-transported object 1000, and the to-be-transported object 1000 is effectively guaranteed to have the set speed V1 when leaving the buffer section D2. The structure is particularly suitable for transportation of coiled steel goods, the cylindrical structure of the coiled steel goods generates rolling friction with the ground when moving, stops rolling after contacting with the damping block 211 and continues to advance in a sliding mode, and generates sliding friction force to achieve the purpose of speed limiting. Meanwhile, it should be noted that the damping block 211 can be lifted by the damping lifter 212 in many structures, such as an electric push rod structure embedded in the damping base 210 shown in fig. 8, the damping base 210 is axially perpendicular to the bottom surface of the damping base 210, the damping block 211 is located on the top surface of the damping base 210 when being reset, and when the damping lifter 212 is started, the damping block 211 is lifted along with the damping lifter 212. The damping lifting device 212 can also be an electromagnet, the bottom of the damping block 211 is provided with an electromagnet with the same magnetism as the damping lifting device 212, when the damping lifting device 212 is started, magnetic thrust is generated due to the repulsion of like poles, and the damping block 211 is ejected and lifted.

Further, as shown in fig. 13, the damping repositor 214 is preferably configured to include a damping spring 2141 and a damping telescoping rod 2142. The damping telescopic rod 2142 comprises a small rod and a large rod sleeved outside the small rod, and the small rod realizes the expansion and contraction of the damping telescopic rod 2142 by moving axially along the large rod; the damping spring 2141 is sleeved outside the damping telescopic rod 2142. The two ends of the damping telescopic rod 2142 are hinged to the lower right corner of the damping inner cavity and the damping block 211 respectively. The damping restorer 214 is contracted by a damping telescopic rod 2142 and restored by being compressed by a damping spring 2141 to generate elastic deformation.

More preferably, in order to shorten the length of the buffer section D2, the damping modules 21 may be arranged in an array arrangement of multiple rows and multiple columns, and arranged in multiple rows perpendicular to the transport direction of the articles to be transported 1000, and arranged in multiple columns along the transport direction of the vessel to be transported 1000. Therefore, when the piece to be transported 1000 passes through the top surface of the damping module 21, the plurality of damping modules 21 in the same row can work simultaneously to generate larger resistance, thereby reducing the number of rows required by the damping modules 21 and realizing the speed limit of the piece to be transported 1000 within a limited length. The mode is more suitable for medium and short distance cargo transportation.

In some embodiments, as shown in fig. 2 and 3, the working section D further includes a preparatory lifting section D3; the preparatory lifting section D3 is positioned between the buffer section D2 and the lifting section D4, is arranged in a left-high and right-low mode, and is provided with a limiting component 3 in the middle. The directional movement also includes that the current to-be-transported object 1000 entering the preparatory lifting section D3 can fall from left to right by means of gravity; if the previous part to be transported 1000 is still at the lifting section D4, the limiting assembly 3 blocks the current part to be transported 1000 and stops falling. If the previous piece to be transported 1000 enters the next working section D, the limiting assembly 3 releases the blocking of the current piece to be transported 1000, and the current piece to be transported 1000 enters the lifting section D4. Can realize that spacing subassembly 3 of this effect is many, for example to light cargo transportation, spacing subassembly 3 can set up to be located the clamping device who prepares to rise section D3 both sides, and it is fixed through the clamp of treating transportation piece 1000 both sides, relies on frictional force to realize treating transportation piece 1000 pause and remove, but this structure does not have the commonality, to the cargo transportation that heavy goods and coil steel class removed with the roll mode, can't produce fine fixed effect.

Have better suitability in order to guarantee spacing subassembly 3, can adapt to the needs of various different weight, specification freight, especially can produce better effect of pausing to the goods that coil steel class transported with the roll mode. As shown in fig. 14 to 17, the lifting section D4 is also provided with a spreader 7 for loading and unloading the article 1000 to be transported. The lifting appliance 7 is in first transmission connection with the lifting device 6; the first drive connection can be any connection for lifting the spreader 7, such as a belt drive or a chain drive. The limiting component 3 is preferably arranged to be embedded in a stop block type structure of the preparatory lifting section D3, can do linear lifting motion along the vertical direction, and can extend out of the preparatory lifting section D3 or be retracted into the preparatory lifting section D3 through linkage with the lifting appliance 7, so that the purposes of blocking and unblocking the to-be-transported piece 1000 are achieved. Here, a pressure sensor 7a can be additionally arranged at the bottom of the lifting section D4, and the limiting assembly 3 and the pressure sensor are electrically connected with the control unit 100. Thus, when the lifting appliance 7 leaves the bottom of the lifting section D4, the pressure sensor 7a does not sense the pressure signal, and the limiting assembly 3 keeps the extending state as shown in fig. 16 and 17, so as to finish blocking the to-be-transported member 1000; when the spreader 7 is at the bottom of the lifting section D4, the pressure sensor 7a senses the pressure signal and sends the pressure signal to the control unit 100, and the control unit 100 controls the limiting assembly 3 to be retracted into the pre-lifting section D3 as shown in fig. 14 and 15 based on the received pressure signal, so as to unblock the element to be transported 1000. Here, only one preferred structure of the limiting component 3 and an example of a linkage mode of the limiting component 3 and the lifting tool 7 are shown, the limiting component 3 can be driven by an electric control hydraulic or pneumatic device, and can also be driven by a motor to lift, so that a lot of structures in the prior art can be used for realizing linkage of the limiting component 3 and the lifting tool 7 and blocking of the limiting component 3 on the to-be-transported part 1000, and a person in the prior art can perform the same or similar design according to the example and the related drawings, and detailed description is omitted here.

In some embodiments, considering that some shapes of the to-be-transported member 1000 enter the lifting section D4, and an accident such as dumping occurs during lifting of the spreader 7, especially for rolled steel goods, the spreader 7 includes a bearing plate 70, a left baffle plate 71, a right baffle plate 72 and a clamping actuator 73, as shown in fig. 19 and 20. The left baffle 71 and the right baffle 72 are respectively hinged at two sides of the bearing plate 70. The carrier plate 70 is used for carrying the object 1000 to be transported. The clamping actuators 73 are respectively located at the joints between the bearing plate 70 and the left baffle 71, and between the bearing plate 70 and the right baffle 72, and can rotate both the left baffle 71 and the right baffle 72 relative to the bearing plate 70, so that the spreader 7 is in a folded closed configuration as shown in fig. 20 or in a horizontally unfolded configuration as shown in fig. 19. The clamping actuator 73 is preferably a telescopic rod structure driven by hydraulic pressure, pneumatic pressure or electric power, and has one end connected to the carrying plate 70 and the other end connected to the left or

right baffle

71 or 72, so that the spreader 7 will be horizontally unfolded or folded to be closed along with the extension and contraction of the clamping actuator 73, but the clamping actuator 73 may be other driving device capable of providing rotary power for the left or

right baffle

71 or 72.

Like this, because hoist 7 can expand and close, just can then realize treating the clamping of transportation 10000 fixed or remove fixedly. As shown in fig. 14 and 15, when the lifting appliance 7 is at the bottom of the lifting section D4 and the to-be-transported object 1000 reaches the bearing plate 70 and is at the lower limit region, the lifting appliance 7 is in a closed state, and the to-be-transported object 1000 is clamped and fixed. As shown in fig. 16 to 20, when the lifting tool 7 drives the to-be-transported object 1000 to ascend until the to-be-transported object 1000 is located at the upper limit region, the lifting tool 7 is in an unfolded state, so that the to-be-transported object 1000 can enter the next working segment D from the bearing plate 70 through the right baffle 72.

Further, as shown in fig. 14 to 17, in order to better control the opening and closing timing of the spreader 7, a lifting sensor group 4 is provided in the lifting section D4. The lifting sensor group 4 comprises an upper limiting sensor 4a in an upper limiting area and a lower limiting sensor 4b in a lower limiting area; the upper limit sensor 4a and the lower limit sensor 4b are preferably photoelectric sensors, and may be other sensors capable of sensing the presence of an object. A pushing device 5 is also arranged beside the upper limit sensor 4 a; the pushing device 5 is preferably an electric push rod and is embedded at the left side of the lifting section D4. As shown in fig. 22, the spreader 7, the lifting sensor group 4, the lifting device 6 and the pushing device 5 are electrically connected to the control unit 100. When the piece to be transported 1000 enters the lifting section D4, is on the spreader 7 and is located in the lower limit region, the lower limit sensor 4a sends a clamping signal to the control unit 100; the control unit 100 controls the lifting appliance 7 to be closed based on the received clamping signal to clamp the to-be-transported part 1000, and then the control unit 100 continues to control the lifting device 6 to be started to enable the lifting appliance 7 to ascend; when the to-be-transported object 1000 rises to the upper limit region, the upper limit sensor 4a sends out an unfolding signal, the control unit 100 controls the lifting appliance 7 to unfold based on the received unfolding signal, and then continuously controls the pushing device 5 to start, so that the push rod of the pushing device 5 extends out and pushes the to-be-transported object 1000 into the next working section D. The intelligent control of the lifting appliance 7, the lifting sensor group 4, the lifting device 6 and the pushing device 5 is realized in the process, so that the operation is more convenient and faster.

More preferably, as shown in fig. 14 to 17, when the lifting appliance 7 is in the lower limit region, the right baffle 72 is in the folded state, and when the transportation member 1000 enters the bearing plate 70, the left baffle 71 is also switched to be in the folded state, so that the lifting appliance 7 is in the closed state. The right baffle 72 is in a folded state to prevent the to-be-transported object 1000 from moving forward due to inertia after entering the lifting appliance 7, so as to impact the side wall of the lifting section D4, and the to-be-transported object 1000 is deviated from the central vertical line of the lifting appliance 7, so that the to-be-transported object 1000 falls down during lifting, and safety accidents are caused.

Furthermore, as shown in fig. 14 and 18, a fool-proof portion 9 is disposed at the top of the working section D, and the fool-proof portion 9 is a step of a right gap of the upper limiting area. When the hanger 7 is in the upper limit region and in the unfolded state, the end of the right baffle 72 is lapped on the fool-proof portion 9. The design of the fool-proof part 9 can effectively ensure that the lifting appliance 7 can descend only when the right baffle plate 72 is in a folded state, thereby preventing the to-be-transported piece 1000 from directly impacting the side wall of the lifting section D4, causing the position of the to-be-transported piece 1000 to deviate from the central vertical line of the lifting appliance 7, and causing potential safety hazards of dumping,

The variable amplitude guide rail 14A is adjusted to be matched with the width of the to-be-transported member 1000 by moving the variable amplitude guide rail 14A to adjust the distance between the variable amplitude guide rail and the first guide rail 12A, so that the subsequent motion track of the to-be-transported member 1000 is ensured to be consistent with the laying direction of the first guide rail 12A or the second guide rail 12B, and the motion track is prevented from being inclined and blocked. For convenience of operation, the amplitude-varying adjustment device 14B is electrically connected to the control unit 100, and the control unit 100 is used to start and stop the amplitude-varying adjustment device 14B, so that the position of the amplitude-varying guide rail 14A is changed, and the distance between the amplitude-varying guide rail 14A and the first guide rail 12A is adjusted. Meanwhile, in order to enable the part 1000 to be transported to better enter the working section D for transportation, the amplitude variation guide rail 14A is divided into an inclined opening section and a straight section, and the straight section is connected to the end head of the second guide rail 12B; the bevel section is connected to the straight section, and the distance between the bevel section and the first guide rail 12A is gradually reduced along the opening direction of the straight section.
