Description

A kind of cargo transportation system and transportation method

technical field

The invention relates to the field of logistics transportation, in particular to a cargo transportation system and a transportation method.

Background technique

Point-to-point transportation is a common method of logistics transportation, such as common express transportation, railway transportation, port operation transportation, etc., goods are often sent from a fixed starting point to a fixed destination, and the transportation path will change according to the actual situation, but with the social development. With the development and progress, the traditional transportation operation mode is gradually unable to adapt to today's growing logistics demand.

For example, in the process of port operation and transportation, the goods need to be sent from the warehouse to the port. This process is often completed by truck and road transportation. However, this transportation method has the following shortcomings:

(1) The phenomenon of random pick-up and centralized shipment is frequent, the loading and unloading equipment is overloaded during the peak shipment period, and the roads in the factory area are seriously blocked;

(2) The automobile carrier market is scattered, it is difficult to effectively integrate and dispatch transportation resources, and the transportation cost is high;

(3) The transportation of individual goods is very dangerous, and there is a serious safety hazard to public transportation. For example, common steel coil and tube steel, due to their special shape, are easy to fall off and be thrown out due to the small frictional force due to their rolling method if there is an abnormal situation during the transportation process, such as emergency braking or emergency avoidance of a sharp turn. Outside the cargo device, there was even an accident that collapsed the bridge, causing immeasurable casualties.

(4) Heavy-duty trucks produce serious environmental pollution such as carbon emissions, noise, and dust during transportation. Taking carbon emissions as an example, if the annual freight volume is 3 million tons, and according to the carbon emission factor of 1120g/km average value of a 40-ton truck, the carbon emission of this freight volume is about 3494.4 tons per year.

To sum up, there are many problems in the traditional point-to-point transportation method, especially the coiled steel products have great potential safety hazards. Therefore, in view of this situation, it is necessary to adjust, innovate and improve the existing transportation methods.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings. as a limitation of the present invention.

As shown in this application and the claims, unless the context clearly dictates otherwise, the words "a," "an," "an," and/or "the" are not intended to specifically refer to the singular and include the plural. Meanwhile, "left" and "right" in this application are only relative orientation concepts, and do not specifically refer to absolute orientations.

In some embodiments, a cargo transportation system is shown in FIG. 1 . The item 1000 to be transported can be transported from the logistics origin A at the left end to the logistics destination C at the right end. The object to be transported 1000 is preferably a steel coil or other material with a cylindrical or spherical shape that can be rolled and transported. The logistics start point A and the logistics end point C are connected in series with a plurality of work sections D in sequence. In this application, it is through the set work section D that the 1000 pieces to be transported are transported from the logistics starting point A to the logistics terminal C. Using the cargo transportation system of this application, it can deal with the transportation of goods in various scenarios, such as from the storage point to the logistics point in the port operation. The terminal transports goods, traditional road transportation, railway transportation, etc., and for some cargo transportation with potential safety hazards, such as coil steel, tube steel transportation, it also shows its advantages, which can effectively avoid the transportation of coil steel and tube steel parts. , Due to the potential safety hazards during the emergency stop of the truck or the emergency avoidance of the sharp turn, it will be described in detail below.

As shown in Figure 1, according to the straight-line distance between the logistics starting point A and the logistics end point C, a corresponding number of working sections D are configured to connect the two. Of course, if the transportation is short-distance, only one working section D can be set. Not detailed here. As shown in FIG. 1 , a relay station B is also provided between the adjacent work sections D. The relay station B can make the to-be-transported item 1000 stop halfway, and is also convenient for station maintenance and repair.

As shown in FIG. 2 , the working section D includes a sliding section D1 and a lifting section D4 arranged from left to right, and the object to be transported 1000 can perform directional movement in the working section D. The sliding section D1 is set to left high and right low. Here, the sliding section D1 is set high on the left and low on the right, so that after the item to be transported 1000 starts from the logistics starting point A and enters the working section D, it can proceed from left to right along the set path of the sliding section D1 under the action of gravity, and from the top to the top. In order to convert the gravitational potential energy at the left end of the sliding section D1 into the kinetic energy after reaching the right end of the sliding section D1 and obtain the initial velocity V0; in order to achieve this effect, the preferred structure of the sliding section D1 is a certain The slope of the included angle can also be any structure such as a segment of a circular arc or a quasi-circular arc, etc., which can make the object to be transported 1000 fall down on it and obtain the initial velocity V0.

A lifting device 6 is arranged above the lifting section D4, and an upper limit area and a lower limit area are arranged from top to bottom. The lifting device 6 can be arranged in the relay station B, which is convenient for maintenance. The directional movement in the working section D includes: after the transport piece 1000 obtains the initial speed V0 in the sliding section D1, it will continue to advance to the lower limit area of the hoisting section D4, and will be raised to the upper limit area by the lifting device 6, so that The object to be transported 1000 replenishes the gravitational potential energy again.

In this way, the to-be-transported piece 1000 enters the working section D from the logistics starting point A, freely falls in the sliding section D1, converts the gravitational potential energy into kinetic energy and obtains the initial velocity V0, and then relies on the initial velocity V0 to reach the lifting section D4, and in the lifting device 6 Under the action of lifting to the upper limit area and replenishing the gravitational potential energy, enter the next working section D, to "enter the working section D → the sliding section D1 accelerates to the initial speed V0 → reach the lifting section D4 → the lifting section D4 is charged → The way of entering the next work section D" continues to circulate, and finally reaches the logistics end point C to realize the transportation of goods. The device described in this application is especially suitable for coiled steel goods. It has a cylindrical structure that can slide smoothly in the sliding section D1 in a rolling manner and obtain a large initial speed V0. The transportation of similar goods is carried out on a specific route, so there will be no congestion like traditional automobile transportation, and it can also avoid emergency braking and emergency turns, thereby eliminating potential safety hazards. At the same time, the preferred setting method of the hoisting section D4 is vertical orientation, so as to save space; and the lifting device 6 is preferably beneficial to realize the elevator structure for hoisting goods. The bottom of D4; the hoisting section D4 can also be set as a slope, arc-like or arc structure with low left and high right, and the lifting device 6 can be set as a booster, a transmission belt, etc. according to the structure of the hoisting section D4 Any structure that enables the object to be transported 1000 to supplement energy in the hoisting section D4 will not be described in detail here.

Further, the working section D also includes the buffer section D2 shown in FIG. 2 . The buffer section D2 is located between the sliding section D1 and the lifting section D4, and the directional movement further includes: the buffer section D2 decelerates the object to be transported 1000 to the set speed V1. In this way, it is convenient to realize the speed control of the object to be transported 1000, and make it enter the hoisting section D4 at a controllable speed, so as to realize buffering, shock absorption and energy dissipation, and prevent the excessively fast speed from generating a large impact load in the subsequent process. In order to achieve this effect, the buffer section D2 can be a reverse slope with low left and high right, or a circular arc-like road section. In this way, after the transport piece 1000 reaches the buffer section D2, the speed is reduced by means of friction and other means, and when it leaves the buffer section D2, the speed is reduced. Decelerate to set speed V1. The preferred method of the present application is to set a damping device 2 in the buffer section D2 as shown in FIG. It should be noted here that, as a modified structure of the present application, the buffer section D2 is cancelled, and several damping devices 2 are arranged in the sliding section D1 at intervals. The unloading section D1 is continuously accelerated, accelerated to a certain level and then decelerated by the damping device 2 , and so on, so that the speed of the to-be-transported piece 1000 can be controlled when it leaves the sliding and unloading section D1.

In some embodiments, considering that the specifications and weights of the goods are different during the transportation of the goods using the device of the present application, the initial velocity V0 and the momentum generated by the goods after the acceleration in the sliding and unloading section D1 are also different. In order to The resistance generated by the damping device 2 can be adapted to different specifications and weights of goods, so as to better decelerate the goods in the buffer section D2 to the set speed V1 to achieve speed control. As shown in Figure 3, the buffer section D2 is divided into a left and right speed measuring section D21 and a damping speed regulating section D22; the damping device 2 is arranged in the damping speed regulating section D2.

The initial information Y of the item to be transported 1000 can be collected in the speed measurement section D21. The damping device 2 can adjust the damping size based on the initial information Y to reduce the speed of the transport object 1000 . Here, the damping device 2 can be a hydraulic thrust device that is opposite to the moving direction of the object to be transported 1000, and can reduce the speed of different objects to be transported 1000 by generating hydraulic pressures of different sizes; The electromagnetic force is used to realize the deceleration of the different objects to be transported 1000; it can also be a slope resistance device, which can realize the deceleration of the different objects to be transported 1000 by generating a slope opposite to the moving direction of the objects to be transported 1000 and with different slopes. The preferred setting method of the present application is to set the damping device 2 to be composed of a plurality of damping modules 21, the plurality of damping modules 21 are serially connected in series along the moving direction of the object to be transported 1000, and each damping module 21 can generate corresponding resistance to be transported 1000 pieces to slow down. The initial information Y includes the initial speed V0 and weight W of the piece to be transported 1000 collected as shown in FIG. 25 , and the corresponding specifications of the piece to be transported 1000 may also be added. The damping device 2 can determine the number of the damping modules 21 to work according to the collected initial information Y, thereby determining the magnitude of the resistance generated, so as to achieve precise control of the speed of the object to be transported 1000 .

In order to make the control process more intelligent, as shown in FIG. 29 , each working section D is provided with a control unit 100 , and each speed measuring section D21 is also provided with an information collector 8 . The information collector 8 is used to collect the initial information Y, where the information collector 8 includes a speed sensor capable of collecting the initial velocity V0 and a gravity sensor that collects the weight W, and an infrared sensor can also be added to collect the specifications of the item to be transported 1000 . The damping device 2 and the information collector 8 are respectively electrically connected to the control unit 100 . In this way, 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 damping modules 21 to be operated, and then The control will generate a corresponding resistance, so as to achieve the purpose of accurately decelerating the transport piece 1000. Similarly, the damping module 21 can also be implemented by means of electromagnetic, slope resistance, friction, etc., or a combination of the above-mentioned means.

The present application also provides a preferred structure of the damping module 21. As shown in FIGS. 7 to 13, the damping device 2 includes a damping base 210, a damping block 211, a damping lifter 212, a damping support block 213, and a damping resetter 214. The damping base body 210 has a cuboid structure as a whole, is embedded in the bottom surface of the damping speed regulating section D22 and is provided with a damping inner cavity; The damping reset device 214 is a flexible and retractable structure, and one end is hinged to the lower right corner of the damping cavity, and the other end is hinged to the damping block 211 . The damping lifter 212 is arranged on the left side of the bottom of the damping cavity. The damping support block 213 is arranged on the top of the damping cavity, and is symmetrically arranged on the two sides adjacent to the damping reset device 214 in the damping cavity. A left ejection port is formed between the left end of the damping support block 213 and the left side of the damping inner cavity, and a right drop port is formed between the right end of the damping support block 213 and the right side of the damping inner cavity.

8 to 12 are schematic diagrams showing the gradual change of the state of the damping module 21 during the movement of the object to be transported 1000 on the top surface of the damping module 21 from left to right. As shown in FIG. 8 to FIG. 10 , when the damping module 21 is working, the damping lifter 212 lifts the damping block 211 from the left ejection port to the outside of the damping cavity. At this time, the to-be-transported piece 1000 moves to the right until it is in contact with the damping block 211 . . Then, the damping block 211 moves away from the left ejection opening together with the to-be-transported piece 1000 , and moves to the top of the damping support block 213 . During the rightward movement in FIGS. 10 and 11 , the object to be transported 1000 will continue to be subject to the sliding frictional resistance given to the damping block 211 by the top surface of the damping module 21 , and the elasticity of the damping block 211 given to the damping block 211 by the constant contraction of the damping reset device 214 . Deformation resistance, thereby realizing the deceleration of the object to be transported 1000 . As shown in FIG. 12 , when the damping block 211 moves directly above the right landing port, it will fall freely by gravity, thereby releasing the contact with the object to be transported 1000 . The damping reset device 214 will restore the elastic deformation, so that the damping block 211 will bounce back to the position shown in FIG. 8 and reset; and the transportation member 1000 will continue to move to the right and reach the next damping module 21 to repeat the above-mentioned deceleration process, and so on, the damping device 2 Thus, the speed control of the item to be transported 1000 is realized, and the set speed V1 is effectively ensured when the item to be transported 1000 leaves the buffer section D2. This structure is especially suitable for the transportation of coiled steel goods. The cylindrical structure of coiled steel goods causes rolling friction with the ground when it moves, and will stop rolling after contacting the damping block 211 and continue to move forward in a sliding manner. And the sliding friction force is generated to achieve the purpose of speed limiting. It can be seen that for coiled steel goods, after the damping block 211 contacts the to-be-transported piece 1000, its movement mode and frictional mode can be changed, so that rolling becomes sliding, rolling friction It becomes sliding friction, and after the contact is released, the original movement mode and friction mode of the to-be-transported piece 1000 can be restored, and better deceleration control of coiled steel goods can be performed. At the same time, it should be noted that there are many structures that can realize the lifting and lowering of the damping block 211 by the damping lifter 212, which can be the electric push rod structure embedded in the damping base 210 as shown in FIG. When the damping block 211 is reset, it is on the top surface of the damping base 210 . When the damping lifter 212 is activated, the damping block 211 will follow the damping lifter 212 to rise. The damping lifter 212 can also be an electromagnet. The bottom of the damping block 211 is installed with an electromagnet with the same magnetism as the damping lifter 212. When the damping lifter 212 starts, due to the repulsion of the same sex, a magnetic thrust will be generated, which will reduce the damping lifter 212. Block 211 "Ejection" goes up.

Further, as shown in FIG. 13 , the preferred structure of the damping reset device 214 is to include a damping spring 2141 and a damping telescopic rod 2142 . The damping telescopic rod 2142 includes a small rod and a large rod sleeved outside the small rod. The small rod can move along the axial direction of the large rod to realize the expansion and contraction of the damping telescopic rod 2142 ; the damping spring 2141 is sleeved outside the damping telescopic rod 2142 . Both 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 reset device 214 is contracted by the damping telescopic rod 2142, and is reset by elastic deformation generated by the damping spring 2141 being compressed.

More preferably, in order to shorten the length of the buffer section D2, the damping modules 21 can be arranged in a multi-row and multi-column array layout, and arranged in a plurality of rows along the transportation direction of the objects to be transported 1000, and along the transportation direction of the ship 1000 to be transported. Set up multiple columns. In this way, when the object to be transported 1000 passes through the top surface of the damping modules 21, multiple damping modules 21 in the same row can work at the same time to generate greater resistance, thereby reducing the number of columns required by the damping modules 21 and realizing the treatment within a limited length. 1000 pieces of transport are speed-limited. This method is more suitable for medium and short-distance cargo transportation.

In some embodiments, as shown in FIG. 2 and FIG. 3 , the working section D further includes a preliminary lifting section D3; the preliminary lifting section D3 is located between the buffer section D2 and the lifting section D4, and is arranged at a high left and a low right , and there is a limit component 3 in the middle. The directional movement also includes that the current to-be-transported piece 1000 entering the preparatory lifting section D3 can fall from left to right by gravity; if the previous to-be-transported piece 1000 is still in the lifting section D4 at this time, the limiting component 3 will remove the current to-be-transported piece 1000 . Piece 1000 blocks and stops falling. If the previous piece 1000 to be transported enters the next working section D at this time, the limiting component 3 releases the blocking of the piece 1000 currently to be transported, and makes the piece 1000 currently to be transported enter the hoisting section D4. There are many limit components 3 that can achieve this effect. For example, for light cargo transportation, the limit components 3 can be set as clamping devices located on both sides of the preparatory lifting section D3. The friction force realizes the suspension of the movement of the object to be transported 1000, but this structure is not universal, and cannot produce a good fixing effect for the transportation of heavy goods and goods such as coiled steel that move in a rolling manner.

In order to ensure better applicability of the limiter assembly 3, it can meet the needs of the transportation of goods of various weights and specifications, and especially can produce a better suspension effect for goods transported in a rolling manner such as coiled steel. As shown in FIGS. 14 to 17 , the hoisting section D4 is further provided with a spreader 7 for loading and unloading the object to be transported 1000 . The spreader 7 is connected with the lifting device 6 for a first transmission; the first transmission connection here can be any connection mode such as belt drive or chain drive that enables the spreader 7 to lift and lower. The limit component 3 is preferably set as a block-like structure embedded in the preliminary lifting section D3, and can perform linear lifting and lowering motions in the vertical direction, and can be extended out of the preliminary lifting section D3 by linkage with the spreader 7 or It is brought back into the preparatory lifting section D3, so as to achieve the purpose of blocking and unblocking the to-be-transported piece 1000. Here, a pressure sensor 7a can be installed at the bottom of the hoisting section D4, and both the limiting component 3 and the pressure sensor are electrically connected to the control unit 100. In this way, when the spreader 7 leaves the bottom of the hoisting section D4, the pressure sensor 7a does not sense the pressure signal, and the limiting assembly 3 remains in the extended state as shown in FIG. 16 and FIG. At the bottom of the hoisting 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 limit assembly 3 based on the received pressure signal, as shown in FIG. 14 and FIG. 15. within segment D3, thereby releasing the blocking of the object to be transported 1000. This is just a preferred structure of the limiter assembly 3, and an example of the linkage between the limiter assembly 3 and the spreader 7. The limiter assembly 3 can be driven by an electronically controlled hydraulic or pneumatic device, or it can be driven by a motor to realize lifting and lowering. , it can be seen that there are many prior art structures that can realize the linkage between the limit assembly 3 and the spreader 7 and realize the blocking of the limit assembly 3 to the transport piece 1000. The prior art can perform the same or similar according to the above examples and related drawings. design, which will not be described in detail here.

In some embodiments, considering that after certain shapes of items to be transported 1000 enter the hoisting section D4, accidents such as dumping may occur during the hoisting process of the spreader 7, especially for goods that are easy to roll such as coiled steel, so as As shown in FIGS. 19 and 20 , the setting hoist 7 includes a carrier plate 70 , a left baffle 71 , a right baffle 72 and a clamping driver 73 . The left baffle 71 and the right baffle 72 are hinged on both sides of the carrying plate 70 respectively. The carrier plate 70 is used to carry the item 1000 to be transported. The clamping drivers 73 are located at the junctions between the carrying plate 70 and the left baffle 71, and between the carrying plate 70 and the right baffle 72, respectively, and can rotate the left baffle 71 and the right baffle 72 relative to the carrying plate 70, so that the The spreader 7 is in a folded closed shape as shown in FIG. 20 or a horizontally unfolded shape as shown in FIG. 19 . The clamping driver 73 is preferably a hydraulic, pneumatic or electric driven telescopic rod structure, and one end is connected to the carrier plate 70, and the other end is connected to the left baffle 71 or the right baffle 72. In this way, with the expansion and contraction of the clamping driver 73, To make the spreader 7 in a horizontally unfolded state or a folded and closed state, of course, the clamping driver 73 can also be other driving devices capable of providing rotational power to the left baffle 71 or the right baffle 72 .

In this way, since the spreader 7 can be unfolded and closed, it is possible to further realize the clamping fixation or release fixation of the object to be transported 10000 . As shown in FIGS. 14 and 15 , when the spreader 7 is at the bottom of the hoisting section D4, and the to-be-transported piece 1000 reaches the carrier plate 70 and is in the lower limit area, the spreader 7 is in a closed state, and the to-be-transported piece 1000 is loaded. Clip fixed. As shown in FIGS. 16 and 25 , when the spreader 7 drives the piece to be transported 1000 up until the piece to be transported 1000 is in the upper limit area, the spreader 7 is in the unfolded state, so that the piece to be transported 1000 can be transported by the carrier plate 70 through the right stop Plate 72 enters the next working section D.

Further, as shown in FIGS. 14 to 17 , in order to better control the timing of unfolding and closing of the spreader 7 , a lift sensor group 4 is provided in the hoisting section D4 . The lift sensor group 4 includes an upper limit sensor 4a in the upper limit area and a lower limit sensor 4b in the lower limit area; both the upper limit sensor 4a and the lower limit sensor 4b are preferably photoelectric sensors, and can also be other sensors capable of sensing the presence of objects . A pushing device 5 is also provided on the side of the upper limit sensor 4a; the pushing device 5 is preferably an electric push rod, and is embedded in the left side of the lifting section D4. As shown in FIG. 29 , the spreader 7 , the lifting sensor group 4 , the lifting device 6 and the jacking device 5 are respectively electrically connected to the control unit 100 . When the piece 1000 to be transported enters the hoisting section D4 and is on the spreader 7 and in the lower limit area, the lower limit sensor 4a sends a clamping signal to the control unit 100; the control unit 100 controls the spreader based on the received clamping signal 7 is closed to realize the clamping of the piece to be transported 1000, and then the control unit 100 continues to control the lifting device 6 to start, so that the spreader 7 rises; The unit 100 controls the spreader 7 to deploy based on the received deployment signal, and then continues to control the ejection device 5 to activate, so that the push rod of the ejector device 5 extends and pushes the to-be-transported piece 1000 into the next working section D. This process realizes the intelligent control of the spreader 7 , the lifting sensor group 4 , the lifting device 6 and the jacking device 5 , which makes the operation more convenient.

More preferably, as shown in FIGS. 14-17 , when the spreader 7 is in the lower limit area, the right baffle 72 is in a folded state, and when the transport piece 1000 enters the carrier plate 70 , the left baffle 71 is also switched to be in a folded state , so that the spreader 7 is in a closed state. The right baffle 72 is in the folded state in order to prevent the piece to be transported 1000 from continuing to move forward due to inertia after entering the spreader 7 , thereby colliding with the side wall of the hoisting section D4 , so that the position of the piece to be transported 1000 deviates from the spreader 7 The vertical line of the center, resulting in tipping during lifting, resulting in a safety accident.

Further, as shown in Fig. 14 and Fig. 18 , the top of the working section D is provided with a foolproof part 9, and the foolproof part 9 is a notch step on the right side of the upper limit area. When the spreader 7 is in the upper limit area and in the unfolded state, the end of the right baffle 72 overlaps with the foolproof portion 9 . The design of the foolproof part 9 can effectively ensure that the spreader 7 can be lowered when the right baffle 72 must be in a folded state, thereby preventing the above-mentioned parts to be transported 1000 from directly hitting the side wall of the hoisting section D4, causing the position of the parts to be transported 1000 to deviate from the hoisting part. The center vertical line with 7, thus causing the safety hazard of dumping.

In some embodiments, in order to more effectively avoid the problem of road congestion during transportation and better dispatch transportation resources, the device of the present application adopts the method of underground transportation, which will be described in detail below:

As shown in FIG. 1 , the working section D is provided with a guide rail assembly 1 . The guide rail assembly 1 includes a first guide rail 12A and a second guide rail 12B arranged in pairs as shown in FIG. 4 . The working section D is a pre-buried channel. The first guide rail 12A and the second guide rail 12B are laid along the opening direction of the working section D to form a transport guide rail group; Underground transportation, special line transportation, avoid road congestion.

Since the object to be transported 1000 is transported underground, in order to prevent safety accidents such as collapse, as shown in FIG. 4 , the guide rail assembly 1 further includes a jacking pipe 11 and a guide rail base 13 . The jacking pipe 11 is a hollow pipe structure and is sheathed in the channel formed by the working section D. The guide rail base 13 may be concrete laid in the jacking pipe 11 , and the first guide rail 12A and the second guide rail 12B are arranged in pairs and fixed on the surface of the guide rail base 13 . Relying on the support of the jacking pipe 11, the working section D is reinforced to avoid collapse. At the same time, devices for monitoring and detecting the fire protection and settlement of the pipe jacking 11 can be added on the working section D, such as pressure sensors, etc., which can timely feedback the abnormal situation to the platform or the operator to ensure the safety and effectiveness of the transportation work.

In order to define the transportation direction of the to-be-transported object 1000 and constrain the movement route during transportation, as shown in FIG. 5 and FIG. 6 , the guide rail assembly 1 further includes a luffing guide rail 14A and a luffing adjusting device 14B. The luffing guide rail 14A is located at the leftmost end of the sliding section D1, and is serially connected to the end of the second guide rail 12B, and is paired with the first guide rail 12A to form a luffing guide rail group. The luffing guide rail 14A is movably connected to the guide rail base 13 and changes the distance from the first guide rail 12A by moving in a direction perpendicular to the first guide rail 12A. The luffing adjusting device 14B is connected to the luffing guide rail 14A, and provides a driving force for the movement of the luffing guide rail 14A. Here, the luffing adjusting device 14B can be a plurality of electric push rods vertically arranged on the outside of the luffing guide rail 14A, and the ends are fixed on the outer side wall of the luffing guide rail 14A, so that the luffing adjusting device 14B can be powered on to generate a thrust that can push the luffing guide rail. 14A moves. The distance between the luffing guide rail 14A and the first guide rail 12A is adjusted by moving to make it fit the width of the piece to be transported 1000 , thereby ensuring that the movement track of the piece to be transported 1000 in the future is consistent with the laying direction of the first guide rail 12A or the second guide rail 12B. Consistent to avoid sticking when the motion trajectory is tilted. For ease of operation, the luffing adjusting device 14B is electrically connected to the control unit 100 , and the luffing adjusting device 14B can be started and stopped through the control unit 100 , so that the luffing guide rail 14A can change its position and adjust the distance from the first guide rail 12A. At the same time, in order to make the piece 1000 to be transported better enter the working section D for transportation, the luffing guide rail 14A is divided into an oblique section and a straight section. The straight section is connected to the end of the second guide rail 12B; the oblique section is connected to the straight section. , and the distance from the first guide rail 12A gradually decreases along the opening direction of the straight section. That is, the luffing guide rails 14A and the first guide rails 12A are in the shape of a "funnel" that is large at the top and small at the bottom, and the to-be-transported piece 1000 can easily enter and gradually tighten during the falling process, so as to restrict its movement path.

In some embodiments, as shown in FIG. 29 , the transportation system of the present application is also configured with an overall controller 110 . The master controller 110 and the control units 100 of each work section D perform unified scheduling and deployment, which makes the control of this transportation system more convenient.

The transportation system of the present application also has supporting methods of use, which are as follows:

As shown in Fig. 21, before the transportation, the m pieces of the same batch of items 1000 to be transported are numbered and recorded as "the first item to be transported, the second item to be transported ...... the pth item to be transported" ...the mth shipment". For the convenience of explanation, the n working sections D in the transportation system are also numbered, and recorded as "the 1st working section, the second working section...the qth working section...the nth working section. Section", in the same way, the sliding section D2 in the qth working section is recorded as the qth sliding section, the lifting device 6 in the qth working section is recorded as the qth lifting device, and so on. Before starting to be transported, all the items 1000 to be transported in the same batch are stored in the logistics origin A. The usage of this application is as follows:

Step S10: p=j, j=1, start preparing for the transportation of the p-th to-be-transported item.

Step S30: The p-th item to be transported starts from the logistics starting point A and enters the first working section.

Step S100: the p-th to-be-transported piece enters the q-th sliding section to obtain the initial speed V0, q=i, i=1.

Step S200 : the p-th to-be-transported item enters the q-th buffer section and the speed is limited to the set speed V1 .

Step S300: The p-th item to be transported enters the q-th preparatory lifting section, and is ready to enter the q-th lifting section.

Step S400 : the p-th to-be-transported piece enters the q-th lifting section, is loaded on the q-th spreader, and is in the lower limit area.

Step S500: Activate the q-th lifting device to lift the p-th item to be transported to the upper limit area.

Step S600: Step S650 is included: q=i+1; the p-th to-be-transported piece is pushed out of the q-th lifting section, and enters the q=i+1-th sliding section. In step S650, the current item 1000 to be transported enters the next work section D.

Step S700: The p-th piece to be transported obtains the initial velocity V0 in the q=i+1-th sliding section, and then returns to step S200. In step S700, the current to-be-transported piece 1000 enters the next work section D and starts to cycle through the above steps, and continues to advance.

Further, considering that the entire transportation process should be carried out continuously, after the current item to be transported 1000 enters the hoisting section D4 of the current working section D, the next item to be transported 1000 should reach the sliding section D1 of the current working section D at this time. , in this way, when the current item 1000 to be transported reaches the upper limit area from the lower limit area until the spreader 7 descends to the bottom surface of the hoisting section D4 again, the next item 1000 to be transported just decelerates and buffers through the sliding section D1 Section D2 decelerates, reaches the lower limit area of the hoisting section D4, and is on the spreader 7, so that the whole process is continuously carried out. In order to realize continuous transportation, the use method of the transportation system should also include the following steps as shown in Figure 22:

Step M100: Goods determination: determine whether P is equal to m; that is, determine whether all the items to be transported have entered the work section D. If the goods are determined to be yes, then step M201 is executed, and if the goods are determined to be no, then step M200 is executed. Step M100 is located after step S400 and executed synchronously with step S500.

Step M200: p=j+1; and return to step S30. That is, after the current item 1000 to be transported enters the hoisting section D4, the next item 1000 to be transported should start from the logistics starting point A and enter the first working section to start transporting.

Step M201 : all the items to be transported in the batch are transported. At this time, the operator does not carry out the conveying operation of the items to be transported 1000 at the logistics starting point A, or waits for all the items to be transported in the batch to arrive at the logistics end point C.

At the same time, it should be pointed out that, assuming that the time required for the piece 1000 to be transported to rise from the lower limit area to the upper limit area in the hoisting section D4 is T1, and the time required for the spreader 7 to descend to the bottom surface of the hoisting section D4 again is T2, then the theoretical If it needs to be transported continuously, the total time T0 = T1 + T2 of the item to be transported from the starting point of the sliding section D1 until it reaches the lower limit area of the hoisting section D4, considering the actual situation, T0 should be greater than T1 + T2, that is The transportation system of the present application formulates the transportation rhythm of the to-be-transported piece 1000 to carry out the transportation work according to the time T, and the time difference ΔT=T0-(T1+T2) is used as the suspension and waiting time of the to-be-transported piece 1000 in the preparatory lifting section D3; The beat T and time difference ΔT are adjusted by the operator according to actual experience

Similarly, in this transportation system, the number of work sections D is also limited. Assuming that the total number of work sections D is n, step S600 should also include as shown in FIG. 23 :

Before step S650, step S610: make a transport decision: decide whether q is equal to n. If the transportation determination is yes, then step S630 is performed, and if the transportation determination is negative, then step S650 is performed.

Step S630: The P-th item to be transported reaches the logistics end point C.

In some embodiments, as shown in FIGS. 24 and 25 , it is necessary to precisely decelerate the object to be transported 1000 in the buffer section D2, so step S200 specifically includes:

Step S210: The p-th to-be-transported item enters the q-th speed-measuring section and is collected by the q-th information collector to collect initial information Y.

Step S230 : the qth information collector sends the collected initial information Y to the qth control unit, and the qth control unit controls the qth damping device to adjust the damping size based on the initial information Y.

Step S250 : the p-th item to be transported enters the q-th speed-adjusting section, the q-th damping device limits the speed of the item to be transported to the set speed V1 , and then step S300 is executed.

Further, it should also include step S270 after step S250 and performed in synchronization with step S300: the qth damping device is reset. That is, after the speed of the current item to be transported 1000 is limited in the buffer section D2, the damping device 2 should be reset to prepare for the speed reduction of the next item to be transported. As shown in FIG. 25 , the initial information Y includes the initial speed V0 and weight W of the item to be transported 1000 , etc., and information such as the specifications of the item to be transported 1000 may also be added.

In some embodiments, as shown in FIG. 26 , the purpose of step S300 is to avoid a conflict situation in which the current item to be transported 1000 and the previous item to be transported 1000 exist in the hoisting section D4 at the same time, specifically:

Step S310: the p-th item to be transported enters the q-th preparatory lifting section

Step S330: Perform limit determination: determine whether the qth spreader is located at the bottom of the hoisting section; If the determination is yes, step S351 is performed; if the determination is negative, step S350 is performed.

Step S351 : the qth limiting component is retracted, so that the pth piece to be transported continues to move forward, and then step S400 is continued. That is, the spreader 7 is on the bottom surface of the hoisting section D4. At this time, the hoisting section D4 has no previous piece 1000 to be transported, and the current piece 1000 to be transported can enter the hoisting section D4.

Step S350 : the qth limiting component pops up, and the pth to-be-transported piece is suspended in the qth preparatory lifting section, and the process returns to step S330 . That is, the spreader 7 is not on the bottom surface of the hoisting section D. At this time, the previous piece 1000 to be transported already exists in the hoisting section, and the current piece 1000 to be transported is suspended from entering the hoisting section D.

In some embodiments, as shown in FIG. 27 , step S500 specifically includes:

Step S510: the p-th to-be-transported item enters the q-th lifting section and is in the lower limit area, at this time the q-th lower limit sensor is triggered as shown in FIG. 29 and FIG. 15 , and sends the lower limit area signal to the q-th control unit; The qth control unit controls the folding of the left baffle of the qth spreader based on the received lower limit area signal, and cooperates with the right baffle to fix the pth to-be-transported piece.

Step S530 : As shown in FIG. 29 and FIG. 16 , the qth control unit controls the qth lifting device to start, so that the qth spreader starts to leave the lower limit area and starts to rise, and at the same time the qth limit component bounces up.

Step S550: The p-th piece to be transported reaches the upper limit area with the rise of the q-th spreader

Step S570: As shown in FIG. 29 and FIG. 17, the qth upper limit sensor is triggered, and sends the upper limit area signal to the qth control unit; the qth control unit controls the deployment of the left and right baffles of the qth spreader. .

In some embodiments, it should also include step S700A performed synchronously with step S700 and located after step S650. Step S700A includes:

Step S710A: the qth control unit controls the folding of the right baffle of the qth spreader

Step S730A: The qth control unit controls the qth lifting device to start, so that the qth spreader starts to descend

Step S750A: The qth spreader reaches the bottom surface of the qth hoisting section, and at the same time, the qth limiter assembly is retracted.

The advantages of adopting the transportation system and method of use of the present application are analyzed below with an example: Suppose the piece 1000 to be transported is coiled steel, and the coiled steel is transported from the port to the wharf by automobile, that is, the logistics start point A to the logistics end point C. Coil steel is about 3 million tons/year (Q≈150,000 pieces/year), and the road transportation distance is about 10.4 kilometers, and the time is about 21 minutes. The main issues at present include:

(1) The phenomenon of random pick-up and centralized shipment is frequent, the loading and unloading equipment is overloaded during the peak shipment period, and the roads in the factory area are seriously blocked;

(2) The automobile carrier market is scattered, and it is difficult to effectively integrate and dispatch transportation resources;

(3) The transportation of coil steel is very dangerous, and there are serious traffic safety hazards.

parameter settings

The straight-line distance from the coil steel warehouse to the port, that is, the logistics starting point A to the logistics ending point C, is S≈7 kilometers. Calculated on the basis of 300 working days per year and 12 hours of daily working time, taking 1.5 times the peak factor, and the system production tact T=0.96 minutes/piece. The rolling friction coefficient of the coiled steel clad material and the guide rail is taken as μ=0.01. Set the height of the hoisting section D4 to be 15 meters, and the slope of the sliding section D1 to be α1 = 2. The horizontal distance l ₁ =430 meters of the sliding section D1, and the length l ₂ =1070 meters of the buffer section D2. That is, each working section D is about 1500 meters, and the number of working sections D can be obtained at the same time n≈5.

According to T and h, it can be concluded that the lifting speed of the hoisting equipment must be greater than 7.8 m/min.

Cost and Benefit Analysis

The cost of the system mainly includes construction cost and operating cost. Among them, the construction cost is mainly the construction cost of the pipe jacking 11 . The cost of pipe jacking with a diameter of 3 meters is about 10 million yuan/km. The working wells are calculated at a distance of 150 meters and a unit price of 2 million yuan per unit. 47 working wells are required, and the total construction cost is 164 million yuan. Taking into account the purchase of lifting equipment and other costs, the construction cost is 300 million yuan. Calculated according to the 20-year depreciation period, the annual depreciation amount is 15 million yuan. The operating costs are mainly the power consumption of the crane, ie the lifting device 6 . According to the crane power of 30kw and the electricity cost of 0.677 yuan/kwh, the annual power consumption of 3 million tons of coiled steel is about 244,000 yuan.

Road transportation mainly considers transportation and loading and unloading costs, and the car transportation distance from the factory to the port is about 10.4 kilometers. The road transportation rate is about 0.8 yuan/ton kilometer, and the annual cost of transporting 3 million tons of coil steel is 24.96 million yuan/year; the cost of two loading and unloading is about 12 million yuan/year. In addition, road transportation will also cause environmental pollution such as carbon emissions, noise, and dust. Calculated according to the carbon emission factor of 1120g/km on average for a 40-ton truck. The carbon emission of this freight volume is about 3494.4 tons per year.

It can be seen that, compared with the traditional road transportation system, the transportation system of the present application can effectively achieve the purpose of cost reduction and energy saving, and at the same time, it can avoid traffic congestion and safety accidents, and is a new type of logistics transportation worthy of promotion.
