TECHNICAL FIELD
[0001] The present application relates to a flat warehouse board material in and out of warehouse system, and also relates to a flat warehouse high material layer board material in and out of warehouse method, belonging to the technical field of flat warehouse distribution and discharge. BACKGROUND
[0002] The stockyard of the flat warehouse is rectangular, the width of the stockyard is relatively wide, often reaching 30-40 meters, and there is a trend of becoming wider and wider, and the depth sometimes reaches more than 200 meters. Special discharge machines are needed for discharging, the discharge machines extend along the full width direction of the flat warehouse and advance along the depth direction of the flat warehouse; the middle part of the width direction of the flat warehouse is provided with a pit extending along the full depth direction. The discharge machine advances while conveying the material in the width direction to the central pit of the flat warehouse, and a buried scraper conveyor is arranged in the pit to convey the material outside the warehouse.
[0003] The Chinese invention patent with the publication number CN114920030B discloses a method for the in and out of warehouse of granular material of a flat warehouse without a pit, which is mainly suitable for the discharge of materials such as soybeans and rapeseeds with good fluidity. For materials such as soybean meal that are prone to board consolidation, they will stick together into a consolidated whole similar to concrete after long-term stacking. This technical solution cannot be applied to such materials. In addition, the material is distributed only along the center line of the top of the warehouse, forming a single-peak material pile with high center and low sides, and the height difference between the center and the wall is too large, which affects the effective capacity.
[0004] The Chinese invention patent application with the publication number CN116002405A discloses a high material layer board material discharge machine, a flat warehouse discharge system and a discharge method. The arch breaking auger is inserted into the board consolidated material in front of the high position in advance, rotates and transversely reciprocates, and draws a transverse continuous cut on the cliff surface of the front upper material layer to make it collapse downward in advance, which facilitates the discharge machine to convey the material to the pit. However, this technical solution still has the following problems in practice: in order to increase the storage capacity per unit area, the material pile is getting higher and higher, and high material layers of more than 10 meters are becoming more and more common. Although the arch breaking auger is inserted into the board consolidated material in front of the high position in advance, the transversely cut opening is about 2 meters away from the ground, the board consolidated material pile above is very high and heavy, and it is difficult to break. As the lower part is hollowed out, the material pile above will still collapse, damaging the discharge machine.
[0005] The traditional pit needs a large civil enclosure structure to accommodate the head end walking mechanism of the discharge machine, and the top of the civil enclosure structure is often connected to the middle partition wall through a long slope. The construction period is long, and the cost is high, which further reduces the effective storage space.
[0006] A kind of unloading door device is disclosed in Chinese invention patent with publication No.CN 214567948U, including symmetrical open-close flap, the top of two flaps is symmetrically hinged on both sides of flap top beam, the back of two flaps is hingedly connected with connecting rod in middle part, the lower end of connecting rod is hingedly connected on connecting rod hinge seat;The bottom of flap top beam is hingedly connected with electric push rod, the bottom of electric push rod is fixed on electric push rod support, electric push rod support and connecting rod hinge seat are fixed on unloading door bottom beam respectively, the front and rear ends of flap top beam are respectively provided with X direction guide wheel, the upper and lower sides of X direction guide wheel are respectively provided with Y direction guide wheel, X direction guide wheel and Y direction guide wheel are embedded in vertical support beam sliding groove of unloading door stand column. The top of unloading door stand column is provided with shed support, the upper side of shed support is fixed with shed, and the shed is symmetrically covered above the top of two flaps in herringbone shape. The technical scheme avoids building civil construction enclosure structure, the upper side of which can normally stack material, expand material space, and facilitate gravity self-flow discharge. However, many components are prone to failure and buried under the material pile, a deep pit must be provided for easy power supply and personnel access to the pit for maintenance. SUMMARY

[0023] Further, the warehouse discharging machine comprises a longitudinal walking mechanism, a material supporting and cleaning mechanism and a transverse discharging mechanism which are installed on the base of the warehouse discharging machine, the material supporting and cleaning mechanism is located above the central pit, the transverse discharging mechanism is symmetrically located on the left and right sides of the material supporting and cleaning mechanism and extends along the width direction of the flat warehouse, the upper end of the central pit is covered with a material transparent cover plate, the central part of the material transparent cover plate in the width direction of the pit is a blind plate, the two sides of the blind plate are respectively a grid capable of leaking material, and the material blocking belts of the material supporting and cleaning mechanism are respectively covered above the two grids and extend along the full length direction of the grid.
[0024] Further, the material supporting and cleaning mechanism further comprises an arcuate aqueduct which is fixed to the middle part of the base of the warehouse discharging machine, the arcuate aqueduct is isosceles trapezoidal and the front and rear ends are close to the grid, the middle part of the arcuate aqueduct is raised and passes above the walking drive shaft of the longitudinal walking mechanism, and the two material blocking belts respectively pass the arcuate aqueduct.
[0025] Further, a material cleaning scraper is arranged between the two arcuate aqueducts, the material cleaning scraper is triangularly wrapped and the bottom side of the triangle is attached above the blind plate, the material cleaning driving sprocket of the material cleaning scraper is located at the top of the warehouse discharging machine, the material cleaning driven sprockets of the material cleaning scraper are symmetrically located on the front and rear sides of the warehouse discharging machine, the material cleaning driven sprockets of the material cleaning scraper are respectively fixed on the material cleaning scraper driven shafts, the two ends of the material cleaning scraper driven shafts are respectively provided with belt cleaning augers, and the belt cleaning augers are respectively located above the material blocking belts and are transported in the direction of the material cleaning scraper.
[0026] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. Not only is the material distributed along the axis of the flat warehouse, but the material is also distributed downwards at multiple points through the multiple support feeding ports of the transverse feeding scraper on both sides of the axis, so that the triangular cross-section of the material pile in the transverse direction of the flat warehouse becomes a trapezoidal cross-section, and most of the space can be used to pile up a material layer of more than 10 meters, which greatly increases the actual storage capacity; the top of the pit is a planar structure, which further improves the effective storage space.
[0027] 2. The high-density material layer about 10 meters in front of the hopper can be broken up from top to bottom in advance, and the arching can be broken up to avoid the formation of a dangerous cliff at the bottom of the material pile during the arching process. The high-density material is gradually broken up and collapses downward in advance, forming a safe slope and preventing the high-density material pile from breaking into large pieces and causing it to overturn and damage the hopper.
[0028] 3. Pre-breaking the collapsing material will form a relatively low and continuous pile of loose material in front of the discharge machine. The discharge machine can easily discharge these low and continuous piles of material at a uniform speed, which can more continuously and stably transport the material to the next production line and ensure the stable supply of material to the production line.
[0029] 4. Divide the entire width of the flat warehouse into several units, and scrape and break up the arches in different areas simultaneously. This will increase the speed of arch breaking and scraping by several times, thereby improving the speed and efficiency of warehouse exit.
[0030] 5. Several discharge walking chains are buried along the depth direction on the ground of the flat warehouse. The discharge machine moves forward along the discharge walking chains, driving the transverse discharge mechanism forward. Two material blocking belts are covered above the pit. The bottom of the material blocking belts is reliably supported by the grid, which can support the material above and prevent the material from leaking in. When discharging, as the discharge machine moves forward, the belt at the part of the discharge machine is pulled away from the grid, so that the material can directly pass through the grid and fall into the pit, where it is sent out by the buried scraper conveyor.
[0031] 6. The complex movable unloading gate, electric push rod, sliding contact line, rollers and other vulnerable parts and fixed structures above the pit have been eliminated, greatly reducing the height of the pit and eliminating the need to set up maintenance passages in the pit. The pit cover does not need to be maintained. In addition, the pit cover can be removed by lifting the belt to maintain the buried scraper conveyor without having to travel a long distance through the closed pit, which improves the safety of maintenance.
[0032] 7. The arch-breaking mechanism and the discharge mechanism are linked, allowing for a certain range of travel speed differences to ensure stable, reliable, and continuous operation of the production line. When the positional deviation between the arch-breaking mechanism and the discharge mechanism is too large, a signal can be sent in time for adjustment to prevent equipment damage. This discharge combination device can achieve fully automatic, unmanned, continuous, and safe material discharge, reducing personnel entry and exit, lowering the risk of safety accidents, and protecting personnel health.

[0052] In the following description of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", 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 the present invention and simplifying the description, and do not mean that the device must have a specific orientation.
[0053] like Figures 1 to 3 As shown, in the material feeding method of the high-layer caking material in the flat warehouse of the present invention, the material feeding steps are as follows: the material outside the warehouse is conveyed along the longitudinal direction of the flat warehouse by the longitudinal feeding scraper 23 located below the top of the flat warehouse. The longitudinal feeding scraper 23 is connected in three sections along the axis of the flat warehouse, and multiple main feeding ports 24 are evenly provided at the bottom of each longitudinal feeding scraper 23.
[0054] The left and right sides of the longitudinal feeding scraper 23 are respectively provided with transverse feeding scrapers 28. The inlet of the transverse feeding scraper 28 receives the material output from the main feeding port 24. The material is fed into the width direction of the flat warehouse through multiple supporting feeding ports 29 at the bottom and can be moved longitudinally along the flat warehouse. The left and right transverse feeding scrapers are staggered in the longitudinal direction and are respectively located in the scraper longitudinal moving frame 27. The two ends of the scraper longitudinal moving frame 27 are respectively suspended below the longitudinal hanging rail 25 on the top of the warehouse through the longitudinal walking mechanism 26.
[0055] The specific steps for receiving fabric into the warehouse are as follows:
[0056] S1. Open the No. 1 main fabric opening closest to the starting point of the fabric and let the fabric fall freely;
[0057] S2. The right-side horizontal fabric scraper moves to connect with the opened main fabric inlet and keeps the material falling freely into the first branch fabric inlet that is connected to the inlet until the material pile below seals the first branch fabric inlet.
[0058] S2. Activate the horizontal fabric scraper on the right side, and the second fabric support opening will drop material freely until the material pile below seals the second fabric support opening; continue in this manner until the fabric at the rightmost fabric support opening is completed.
[0059] S3. Open the next main fabric opening for free material drop, while the left horizontal fabric scraper moves to connect with the opened main fabric opening. Open the first branch fabric opening that connects with the inlet and keep the material dropping freely until the material pile below seals the first branch fabric opening.
[0060] S4. Start the horizontal fabric scraper on the left. The second fabric support opening will drop material freely until the material pile below seals the second fabric support opening. Continue in this manner until the fabric at the leftmost fabric support opening is completed.
[0061] S5. Continue to open the next main fabric opening for free material drop, return to step S2 and repeat until all the fabric is used up.
[0062] The material release procedure is as follows:
[0063] The overhead crane suspends the arch-breaking and scraping device B, which moves longitudinally along the flat warehouse. Multiple sets of arch-breaking screw conveyors on device B scrape the vertical surface of the slab-formed material pile. The material falls into a loose, low pile in front of the discharge machine A below. The discharge machine A moves synchronously along the longitudinal direction of the flat warehouse, sending the material in the width direction of the flat warehouse into the central pit, where it is then sent out of the warehouse by a buried scraper conveyor.
[0064] like Figures 4 to 6As shown, the arch-breaking and material-scraping combined device of the present invention includes a material-scraping machine A extending along the full width of the flat warehouse and an arch-breaking and material-scraping device B. The arch-breaking and material-scraping device B is located above the front side of the material-scraping machine A, and its top is suspended under the overhead crane. The overhead crane extends along the width of the flat warehouse and moves forward synchronously with the arch-breaking and material-scraping device B and the material-scraping machine A.
[0065] like Figures 7 to 11 As shown, the arch-breaking scraping device B includes an arch-breaking swing frame 1 suspended below the crane 10, translation brackets 2 located on both sides of the arch-breaking swing frame 1, and an arch-breaking mechanism located on the translation brackets 2. The crane 10, the arch-breaking swing frame 1, and the translation brackets 2 all extend along the width direction of the flat warehouse.
[0066] The arch-breaking swing frame 1 includes multiple parallel and inverted triangular frames 1a. Each triangular frame 1a has a central vertical rod along its base height line. The middle parts of the two hypotenuses of each triangular frame 1a are connected to each other by a central beam, which improves the strength and rigidity of the triangular frames 1a. The central vertical rods of adjacent triangular frames 1a are connected to each other by a connecting steel frame 1d, making the arch-breaking swing frame 1 a rigid whole. The connecting steel frame 1d includes a rectangular frame, and the diagonal and midpoint of the long side of the rectangular frame are connected to the central connecting block.
[0067] The arch-breaking pendulum frame 1 has pendulum rails at its upper and lower ends on both sides. The pendulum rails include upper pendulum rails 1f and lower pendulum rails 1g, which are parallel to each other and extend along the length of the arch-breaking pendulum frame 1. Specifically, the upper bottom edge of each tripod 1a extends outward to form a tripod upper beam 1b, and the two upper pendulum rails 1f are symmetrically fixed above the two ends of the tripod upper beam 1b. The lower apex of each tripod 1a is welded with a tripod lower beam 1c parallel to the tripod upper beam 1b, and the two lower pendulum rails 1g are symmetrically fixed above the two ends of the tripod lower beam 1c. Thus, the cross-sectional shape of the arch-breaking pendulum frame 1 is an inverted trapezoid that is wider at the top and narrower at the bottom.
[0068] The front and rear sides of the arch-breaking swing frame 1 are symmetrically provided with translation brackets 2. The back of the two translation brackets 2 are supported on the swing frame track by rollers and can be translated along the swing frame track.
[0069] The translation support 2 includes arch-breaking upright beams 2a and rigid trusses 2d. Each arch-breaking upright beam 2a extends vertically, is parallel to each other, and is arranged at equal intervals. Adjacent arch-breaking upright beams 2a are connected to each other as a whole by rigid trusses 2d. The outer frame of each rigid truss 2d is rectangular, and a translation drive seat 2e is provided at the center of each rigid truss 2d. The diagonal and midpoint of the long side of the rectangular frame are welded to the translation drive seat 2e by connecting rods.
[0070] The upper and lower parts of the back of the two broken arch beams 2a are respectively fixed with translation bracket ear seats 2b, and translation bracket rollers 2c are respectively installed below each translation bracket ear seat 2b. Each translation bracket roller 2c is supported in the upper rail 1f or the lower rail 1g of the swing frame.
[0071] Both the upper rail 1f and the lower rail 1g of the swing frame are I-beams. The translation support rollers 2c are set in pairs and symmetrically embedded on both sides of the corresponding I-beams. They can not only roll along the I-beams, but also enable the arch-breaking swing frame 1 to be accurately positioned in its own width direction.
[0072] Two translation drive reducers 4 are installed in the middle of the arch-breaking swing frame 1. The translation support 2 is driven by the translation drive reducers 4 through the translation drive chain 5. The translation drive reducers 4 can be installed symmetrically in the front and back directions. The input end of the translation drive reducer 4 is driven by the translation drive motor 3. The output shaft of the translation drive reducer 4 is equipped with a translation drive sprocket 4a. The translation drive sprocket 4a is connected to the translation driven sprocket 6a through the translation drive chain 5. The translation drive chain 5 is parallel to the swing frame track. The translation driven sprocket 6a is installed on the translation driven shaft 6. The translation driven shaft 6 is supported on the arch-breaking swing frame 1 by a bearing seat.
[0073] Each translation drive seat 2e has a vertical waist-shaped groove 2f at its center. A translation drive block 5a is embedded in the vertical waist-shaped groove 2f of one of the translation drive seats 2e. The root of the translation drive block 5a is cantilevered and fixed to a link of the translation drive chain 5. In this way, the translation drive chain 5 can rotate continuously, avoiding the impact caused by frequent braking and steering.
[0074] Each arch-breaking beam 2a is equipped with an arch-breaking auger 8 parallel to it. The arch-breaking augers 8 on the front and rear sides are arranged in an inverted V-shape. The parts of each arch-breaking auger 8 near the upper and lower ends are supported on their respective arch-breaking beam 2a by bearing seats.
[0075] The middle section of each arch-breaking auger 8 is driven by the output end of the arch-breaking auger reducer 7a via a chain, and the input end of each arch-breaking auger reducer 7a is driven by the arch-breaking auger motor 7. The arch-breaking auger reducers 7a are fixed on the back of the arch-breaking vertical beam 2a.
[0076] In the arch-breaking swing frame 1, the centers of the upper beams 1b of each triangular frame are hinged to the underside of the trolley 10 via swing frame pins 1e. The arch-breaking swing frame 1 matches the width direction of the flat warehouse and is suspended by the trolley 10, moving forward along the depth direction of the flat warehouse, i.e., facing the material pile. When this device presses on the material pile, the arch-breaking swing frame 1 can swing outward at a certain angle. On the one hand, it has self-adaptive capability, allowing for a certain range of error between the scraping device and the forward speed of the discharge machine A on the ground; on the other hand, the tilted arch-breaking swing frame 1 automatically has a counterweight function, making the arch-breaking auger 8 press on the slope of the material pile for easy scraping. In addition, due to the tilt of the arch-breaking swing frame 1, the arch-breaking auger 8 presses obliquely on the material pile, forming a stable slope that is narrow at the top and wide at the bottom after scraping, avoiding the risk of concentrated collapse damaging the discharge machine.
[0077] Each arch-breaking auger motor 7 drives an arch-breaking auger reducer 7a, which in turn drives an arch-breaking auger 8. Taking six arch-breaking augers 8 arranged in the width direction as an example, the width direction of the flat warehouse is divided into six areas. Each arch-breaking auger 8 is only responsible for breaking and scraping material in one-sixth of the area, which greatly improves the scraping speed. The six arch-breaking augers 8 rotate simultaneously, scraping the caking materials such as soybean meal on the slope in front vertically. After the caking materials are scraped off, they fall to the ground. The lower pitch of each arch-breaking auger 8 is greater than the middle and upper pitch, which facilitates the upward conveying or loosening of materials on the ground, and facilitates synchronous discharge by the warehouse discharge machine.
[0078] As each arch-breaking auger 8 rotates, the translation drive motor 3 drives the translation drive reducer 4 to operate. The translation drive reducer 4 drives the translation driven sprocket 6a to rotate through the translation drive sprocket 4a and the translation drive chain 5, and the translation drive chain 5 drives the translation drive block 5a to rotate continuously. The translation drive block 5a is embedded in the vertical waist-shaped groove 2f of the translation drive seat 2e, which drives the translation drive seat 2e and in turn drives the entire translation support 2 to move horizontally along the upper rail 1f and the lower rail 1g of the swing frame.
[0079] When the translation drive block 5a follows the translation drive chain 5 to the lower layer, the translation drive block 5a is located in the lower part of the vertical waist groove 2f, which drives the translation support 2 to move forward. At the same time, each arch-breaking auger 8 rotates and moves forward with the translation support 2 to achieve forward scraping.
[0080] When the translation drive block 5a reaches the upper layer along with the translation drive chain 5, the translation drive block 5a is located in the upper part of the vertical waist groove 2f, which drives the translation support 2 to move in the opposite direction. At the same time, each arch-breaking auger 8 rotates and moves in the opposite direction along with the translation support 2 to achieve reverse scraping. This cycle repeats.
[0081] In addition, arch-breaking augers 8 are installed on both the front and rear sides of the arch-breaking swing frame 1 to facilitate bidirectional material discharge.
[0082] like Figure 4 , Figure 5 , Figures 12 to 15 As shown, the discharge machine includes a discharge traveling mechanism, a material supporting and cleaning mechanism, and a transverse discharge mechanism mounted on the discharge machine base 11. The upper end of the central pit is covered with a material-permeable cover plate. A blind plate 20b is located in the middle of the width of the pit on the material-permeable cover plate. On both sides of the blind plate 20b are material-permeable grids 20a, which are integrated with the blind plate 20b. The transverse discharge mechanism is a ring scraper conveyor 19 that discharges material towards the pit; it can also be a conveying auger.
[0083] The material handling and cleaning mechanism includes a material blocking belt 18, a cleaning scraper 15, and a belt cleaning auger 17. The material blocking belt 18 covers the top of the two grids 20a respectively. One side of the material blocking belt 18 rests on the edge of the pit, and the other side rests on the edge of the blind plate 20b.
[0084] The material-stopping belt 18 extends along the entire length of the grid 20a. A raised, arched aqueduct 3 is located in the middle of the discharge machine. The arched aqueduct 3 is an isosceles trapezoid with smooth transitions at the corners, each equipped with rounded chamfers, belt guide pulleys, or aqueduct guide rollers. The discharge machine's drive shaft 12b is located below the highest point of the arched aqueduct 3. The material-stopping belt 18 ascends over the raised arched aqueduct 3 and then descends back to the top of the grid 20a.
[0085] The two sides of the material-stopping belt 18 are restricted between the two side wall panels of the bow-shaped aqueduct 3. The upper end of the bow-shaped aqueduct 3 is provided with multiple aqueduct limiting rods 3a to prevent the material-stopping belt 18 from dislodging from the trough.
[0086] The two ends of the guide belt 18 are respectively equipped with belt tensioning pulleys 18a. For ease of display, the belt tensioning pulleys 18a at both ends are moved to a position closer to the outlet machine in the figure.
[0087] In the storage state, the baffle belt 18 covers the grid 20a and is reliably supported by the grid 20a, which can bear the weight of the material and reliably seal the pit.
[0088] The middle part of the walking drive shaft 12b is connected to the output end of the outbound walking gearbox 12a. The outbound walking gearbox 12a is fixed on the base of the outbound machine. The input end of the outbound walking gearbox 12a is driven by the outbound walking motor 12.
[0089] The flat warehouse floor is symmetrically equipped with multiple channel steels extending along the entire depth direction. Each channel steel has an upward-facing opening and is equipped with a warehouse exit walking chain 12d. Both ends of the warehouse exit walking chain 12d are equipped with walking chain tensioning mechanisms 12e. Multiple walking drive sprockets 12c are symmetrically arranged on the walking drive shaft 12b. The walking drive sprockets 12c and their steering sprockets are respectively engaged with the warehouse exit walking chain 12d.
[0090] During discharge, as the discharge machine moves forward, the material-blocking belt 18 of the discharge machine turns upward and passes over the discharge machine via the bow-shaped aqueduct 3, creating an open space below the bow-shaped aqueduct 3, exposing the grid 20a. The discharge equipment on the left and right sides of the discharge machine transports the material in the width direction of the flat warehouse to the central pit, where it leaks into the pit through the grid 20a. The buried scraper conveyor 21 in the pit sends the material out of the warehouse, and the material-blocking belt 18 behind the discharge machine covers the pit again.
[0091] Material on the blind flange 20b leaks down from the two grids 20a due to natural collapse, but some material still accumulates. Therefore, a cleaning scraper 15 is installed between the two arched aqueducts 3. The cleaning scraper 15 is triangularly wrapped around the blind flange 20b with its base attached to the top of the blind flange 20b. The cleaning drive sprocket 14a of the cleaning scraper 15 is located at the top of the discharge machine. The blind flange cleaning motor 14 and its reducer are mounted on the intermediate cleaning frame 11a, which is fixed to the discharge machine base 11. The cleaning drive sprocket 14a is installed at the output end of the intermediate cleaning reducer.
[0092] The cleaning driven sprockets 16 of the cleaning scraper 15 are symmetrically located on the front and rear sides of the discharge machine and are fixed on the driven shaft of the cleaning scraper 15. Belt cleaning augers 17 are installed at both ends of the driven shaft of the cleaning scraper. Each belt cleaning auger 17 conveys the material on the baffle belt 18 towards the direction of the cleaning scraper. While pushing the material along the blind plate 20b, the cleaning scraper scatters the material to both sides, allowing it to fall onto the grid 20a through the gap between the scraper and the baffle belt 18.
[0093] The bottom of the arch-breaking swing frame 1 is hinged with a sliding power take-up tube 9, and the top of the discharge machine is hinged with a power take-up sleeve 22. The sliding power take-up tube 9 passes through the power take-up sleeve 22. The insertion depth of the sliding power take-up tube 9 in the power take-up sleeve 22 is allowed to have a certain error. When the forward speed of the arch-breaking scraping device relative to the discharge machine is slower, the insertion depth of the sliding power take-up tube 9 in the power take-up sleeve 22 increases, and the tilt angle of the sliding power take-up tube 9 relative to the horizontal plane becomes larger. When the forward speed of the arch-breaking scraping device relative to the discharge machine is faster, the insertion depth of the sliding power take-up tube 9 in the power take-up sleeve 22 decreases, and the tilt angle of the sliding power take-up tube 9 relative to the horizontal plane becomes smaller.
[0094] An angle sensor is installed on the sliding power take-up tube 9 or the power take-up sleeve 22. When the tilt angle of the sliding power take-up tube 9 relative to the horizontal plane is greater than a set value, the control system increases the forward speed of the vehicle. When the tilt angle of the sliding power take-up tube 9 relative to the horizontal plane is less than the set value, the control system decreases the forward speed of the vehicle.
[0095] Alternatively, a position sensor switch can be installed in the sliding power take-up tube 9 or outside the power take-up sleeve 22. When the insertion depth of the sliding power take-up tube 9 in the power take-up sleeve 22 is less than a set value, the control system reduces the forward speed of the vehicle; when the insertion depth of the sliding power take-up tube 9 in the power take-up sleeve 22 is greater than the set value, the control system increases the forward speed of the vehicle.
[0096] The above description is merely a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Besides the above embodiments, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention. Technical features of the present invention not described can be implemented by or using existing technology, and will not be elaborated here.
