TECHNICAL FIELD

[0001] The present application relates to the technical field of deicing snow blowing equipment, and in particular to a posture regulating device for a side spraying module of a gas jet snow removal vehicle. BACKGROUND

[0002] The timely removal of snow on highways and ice on special sections in winter is very important for road maintenance. The gas jet snow and ice removal vehicle has the technical characteristics of ice and snow removal heat treatment that is different from other technical equipment, and is suitable for non-snow-melting agent spreading operation on highway environmental protection maintenance.

[0003] In the prior art, a patent application discloses related technology of a gas turbine jet snow and ice removal vehicle. For example, patent application No. CN201520321242.0 discloses a snow and ice removal vehicle using gas jet deicing, which uses the cruise state performance to generate high-temperature and high-speed gas flow through a fixed nozzle and a rectangular elbow, enters a gas distributor, and is divided into two paths through the gas distributor. One path blows snow or hammers ice on the ground through a gas hammer nozzle, and the other path removes residual snow or ice on the road surface through a gas shovel nozzle. For another example, patent application No. CN200420096404.7 discloses a gas turbine snow melting electric vehicle. The gas turbine generates electricity to provide power load for the drive and system of the vehicle, and at the same time, discharges high-temperature gas above 200℃ to melt ice and snow, and the melted snow water is blocked by a snow water blocking plate and flows into a water collecting tank. Patent No. CN212454633U discloses a flow stabilizing device suitable for a gas inlet pipeline of a gas turbine, which comprises a first retaining pipe and a second retaining pipe. The two ends of the first retaining pipe are respectively provided with a first connecting flange and a second connecting flange, and the two ends of the second retaining pipe are respectively provided with a first connecting flange and a second connecting flange. The first connecting flange of the first retaining pipe is connected to a downstream natural gas inlet pipe, and the first connecting flange of the second retaining pipe is connected to an upstream natural gas inlet pipe.

[0004] In the existing gas jet snow removal vehicle, the flange type fixed bolt connection is used for the connection interface between the side spraying function module and the gas jet air duct. The advantage is that it can be tightly fixed and connected, and the disadvantage is that it cannot adjust the three postures of the side spraying function module, including the lifting, horizontal vector angle and vertical vector angle, and at the same time, it limits the quick installation of the side spraying function module and the flexible expansion of the control strategy of the side spraying function module. In the single module working mode, the gas jet spraying angle adjustment usually adopts vector nozzle technology, but in the combined function module working mode, it will significantly increase the component cost and the number of hydraulic control subsystems.

Therefore, through this invention, multiple side-spray functional modules can be combined into a working mode, improving the energy utilization rate of the gas jet and increasing operational efficiency. The arrangement and combination of the number and types of side-spray functional modules form an extremely rich operational control strategy, which not only meets the independent operational requirements of each functional module, but also achieves synergistic effects such as the superposition, compensation, and progression of operational efficiency through parameter adjustment between modules.

[0018] (2) In this invention, the angle of the rotating sub-shell in each side spraying functional module can be adjusted. When multiple side spraying functional modules are used together to form a combined functional module, the control strategy between the combined modules and the construction of an operation mode adapted to the working scenario can be completed by adjusting the attitude of each individual side spraying functional module between the combined functional modules.

[0019] (3) In this invention, by utilizing the rotating sub-shell with an open spherical shell structure at the top and connecting the rotating sub-nozzle at the bottom of the rotating sub-shell, the distance between the nozzle and the guide pipe is reduced by extending the guide pipe into the interior of the rotating sub-shell. At the same time, a rotating sub-energy storage section is formed at the rotating sub-shell at the bottom of the expansion section of the guide pipe, forming an energy storage buffer space, so as to realize the flexible setting of the nozzle type. The mechanical parameter adjustment structure constructed thereby has a significantly reduced structural complexity compared with the vector nozzle adjustment technology.

[0020] (4) In this invention, the drain pipe flange and the interface flange are connected by a quick-installation structure. Specifically, the X-shaped wedge block and the fitting block are used for fixed connection.

[0021] (5) In this invention, the rotary auxiliary nozzle interface can be connected to a circular nozzle and a flat nozzle. By adopting a spherical shell structure for the rotary auxiliary shell, a rotary auxiliary energy storage section is naturally formed between the rotary auxiliary shell and the rotary auxiliary nozzle, which can avoid internal variable diameter gas blockage and pressure buildup, and avoid back pressure effect on the gas turbine.

[0040] A flow guide pipe flange 101 is arranged at the inlet end of the flow guide pipe 10; the function module interface 50 includes a connecting pipe 501, and an interface flange 504 arranged on the connecting pipe 501. The function module interface 50 is an interface for splitting, converging and guiding the gas jet of the gas turbine. The function of the flow guide pipe flange 101 is to connect with the function module interface 50, specifically to connect with the interface flange 504 of the function module interface 50 through a quick mounting structure. The lower end of the connecting pipe 501 extends downward from the interface flange 504 and inserts into the flow guide pipe 10. By using a block structure connection, the flow guide pipe 10 in the side spray function module and the function module interface 50 are conveniently mounted up and down.

[0041] In combination Figure 2 As shown, in this embodiment, the side spray function module also includes an upper support block 204 and a lower support block 205 arranged in an upper and lower interval; the rack drive structure includes a drive gear 202, and a passive straight rack 203 and a driven straight rack 201 arranged in an interval; the inner side surfaces of the passive straight rack 203 and the driven straight rack 201 are provided with transmission teeth; the upper and lower ends of the passive straight rack 203 are respectively fixedly connected to the upper support block 204 and the lower support block 205; the upper and lower ends of the driven straight rack 201 are respectively slidingly installed on the upper support block 204 and the lower support block 205; the rotating pair housing 301 is arranged in the interval between the passive straight rack 203 and the driven straight rack 201, and the sector gear belt 302 on the outer wall surface of the rotating pair housing 301 is engaged with the passive straight rack 203 and the driven straight rack 201; the outer side surface of the driven straight rack 201 is also provided with drive teeth and engaged with the drive gear 202 for transmission. The drive gear 202 is driven by a motor.

[0042] Through the above structure, the rotating pair shell 301 and the sector gear belt 302 on the outer wall surface thereof constitute a rotating pair assembly, the driving straight rack 201 and the driving gear 202 constitute a sliding pair assembly, the driving straight rack 201 is driven by the driving gear 202 to realize the up-down linear motion, the driving straight rack 201 is engaged with the sector gear belt 302 on the outer wall surface of the rotating pair shell 301, and then the rotating pair shell 301 is driven to adjust the angle, so as to adjust the spray angle of the rotating pair nozzle 304.

[0043] The upper support block 204 and the lower support block 205 and the passive straight rack 203 and the driving straight rack 201 jointly realize the installation and limiting of the rotating pair shell 301.

[0044] Combining Figure 2 As shown, the drainage tube 10 comprises a straight cylinder segment 102 and an expansion segment 103 arranged at the lower end of the straight cylinder segment 102, and the expansion segment 103 is in the shape of a trumpet mouth; the rotating pair shell 301 is a spherical shell structure with an open upper end, specifically, the spherical shell is formed by being transversely cut at the upper end to form an opening, and the cutting edge is rotated to the maximum or minimum angle adjustment range in contact with the pipe wall of the straight cylinder segment 102. A sliding sealing ring 104 is arranged at the lower end of the expansion segment 103, and the sliding sealing ring 104 is in sliding sealing connection with the inner wall of the rotating pair shell 301.

[0045] Combining Figure 2 As shown, the rotating pair nozzle 304 extends out of the tangential opening of the rotating pair shell 301 and is inclined to the side of the driving straight rack 201, and the tangential position is lower than the minimum angle sliding sealing position; the two tangential positions on the upper and lower surfaces of the rotating pair nozzle 304 are orthogonal, the lower bottom is a plane, and the upper end extends out in an arc at the cutting position. When the driving straight rack 201 moves upward to drive the rotating pair shell 301 to rotate to the limit position, that is, the rotating pair shell 301 rotates counterclockwise to the limit position in the state of Figure 2 When the driving straight rack 201 is higher than the upper arc position of the rotating pair nozzle 304 to avoid interference between the driving straight rack 201 and the rotating pair nozzle 304, the driving straight rack 201 and the sector gear belt 302 on the outer wall of the rotating pair shell 301 always remain in engagement.

[0046] The rotary pair shell 301 located at the lower part of the expansion section 103 forms a rotary pair energy storage section 303. The rotary pair shell 301 acts as a gas jet working nozzle, and the rotary pair shell 301 is connected to the flow guide pipe 10 and in contact with the inner wall of the rotary pair shell 301 through the expansion section 103 of the flow guide pipe 10, and the sliding seal is realized through the sliding seal ring 104. The expansion section 103 should be treated as a circular arc to reduce the sharp angle turbulence of the gas flow. The lower induced gas jet of the flow guide pipe 10 stores energy in the rotary pair energy storage section 303, and the working medium injection is completed by the output of the rotary pair nozzle 304. The rotary pair nozzle 304 can be connected to multiple types of nozzles to adapt to different working scenes.

[0047] In combination Figure 2 , Figure 3 As shown in the drawings, the quick mounting structure includes an X-shaped wedge block 70, a lower matching block 603 arranged on the lower surface of the flow guide pipe flange 101, and an upper matching block 502 arranged on the upper surface of the interface flange 504; a lower clamping groove 604 is arranged on the lower matching block 603, and an upper clamping groove 506 is arranged on the upper matching block 502; the upper end of the X-shaped wedge block 70 is movably clamped in the upper clamping groove 506, and the lower end is fixed in the lower clamping groove 604.

[0048] Specifically, the lower clamping groove 604 and the upper clamping groove 506 are both dovetail groove shapes; the X-shaped wedge block 70 includes a connecting straight block 701, and an upper V-shaped block 702 and a lower V-shaped block 703 arranged on the upper and lower ends of the connecting straight block 701; the included angle between the two side surfaces of the lower clamping groove 604 is equal to the included angle between the two side surfaces of the lower V-shaped block 703; the included angle between the two side surfaces of the upper clamping groove 506 is equal to the included angle between the two side surfaces of the upper V-shaped block 702; a flange clamping groove 503 is arranged on the interface flange 504, the connecting straight block 701 is located in the flange clamping groove 503, and the groove width of the flange clamping groove 503 is greater than the width of the connecting straight block 701.

[0049] The upper V-shaped block 702 of the X-shaped wedge block 70 is matched with the inclined surface of the upper clamping groove 506 of the upper matching block 502 to realize load bearing, fixing and elastic obstacle avoidance; the lower V-shaped block 703 of the X-shaped wedge block 70 is clamped in the lower clamping groove 604 of the lower matching block 603 and is fixed, so that the X-shaped wedge block 70 and the lower matching block 603 form a ratchet structure for supporting the flow guide pipe 10. Specifically, the inner side surface of the lower matching block 603 is arranged as a circular arc surface and is attached to the cylinder wall of the flow guide pipe 10, and the top surface of the lower matching block 603 lifts the flow guide pipe flange 101, realizing overall load bearing of the flow guide pipe 10.

[0050] The X-shaped wedge 70 can realize the elastic obstacle avoidance function. Specifically, the weight of the drainage pipe 10 in the side spraying function module is conducted to the drainage pipe flange 101 by the cooperation of the X-shaped wedge 70 and the upper and lower matching blocks. When the weight of the side spraying function module is less than the upward lifting force when encountering an obstacle, the upper V-shaped block 702 at the upper end of the X-shaped wedge 70 is unlocked with the upper clamping groove 506, and the whole side spraying function module is lifted to avoid the obstacle. Since the groove width of the flange clamping groove 503 is greater than the width of the connecting straight block 701, the gas turbine jet assembly can be slightly deflected to avoid deformation. After passing through the obstacle, the drainage pipe 10 in the side spraying function module is automatically reset due to its own weight.

[0051] In combination with Figure 2 , Figure 3 and Figure 9 , the height of the connecting straight block 701 is H, and the quick mounting structure includes a plurality of X-shaped wedges 70 with different H specifications. Top support shoulders 704 are arranged on both sides of the top of the upper V-shaped block 702, and top support screws 705 are screwed in the top support shoulders 704, with the lower end surface of the top support screws 705 abutting against the top surface of the upper matching block 502. Top welding nuts 706 are welded on the top of the top support shoulders 704, and the top support screws 705 are screwed with the top welding nuts 706 and then screwed downward with the top support shoulders 704. By using a plurality of X-shaped wedges 70 with different H specifications, the height H of the X-shaped wedge 70 is selected according to the height requirement of the side spraying function module nozzle from the ground, and the height of the drainage pipe 10 is adjusted by the top support screws 705 on the top support shoulders 704. In addition, in order to ensure the screwing length of the threads on the top support screws 705 and increase the bearing effect, the top welding nuts 706 are welded on the top of the top support shoulders 704. By using the top welding nuts 706 and the internal threads in the top support shoulders 704, the screwing length of the top support screws 705 is increased, and the bearing performance is ensured.

[0052] In combination with Figure 6 , Figure 8 , a plurality of adjusting pin holes 505 are annularly distributed on the interface flange 504, and a long rectangle hole 2041 corresponding to the position of the adjusting pin hole 505 is arranged on the upper support block 204. An adjusting pin is inserted between the adjusting pin hole 505 and the long rectangle hole 2041 corresponding thereto.

[0053] The horizontal plane vector angle adjustment of the side spraying function module takes the parallel plane of the rotating secondary nozzle 304 and the rear end face of the car body as the initial position, the rotating secondary nozzle 304 is rotated to determine the deflection vector angle, the side spraying function module is connected by pinning between the interface flange 504 and the upper support block 204, and the deflection vector angle of the side spraying function module is standardized to the corresponding standard angle adjusting pin hole 505 of the interface flange 504 of the function module interface 50, so that the side spraying function module and the function module interface 50 are fixed at the deflection angle by pinning.

[0054] In combination with Figure 1, Figure 10 and Figure 11 As shown, the suspension structure 100 includes two spaced-apart support plates 1001 and multiple crossbeams inserted into the two support plates 1001; the crossbeams include two first crossbeams 1002, two second crossbeams 1005, and two third crossbeams 1007; multiple reinforcing plates 1003 are also provided between the two support plates 1001. The upper support block 204 is supported on the two second crossbeams 1005; the lower support block 205 is supported on the two third crossbeams 1007. The functional module interface 50, as a component of the gas jet distributor, has an interface flange 504 supported on the two first crossbeams 1002 of the suspension structure 100.

[0055] Suspension trailer support upper arms 902 are respectively provided on both sides of the support plate 1001. Suspension trailer support lower arms 904 are connected between the lower ends of the suspension trailer support upper arms 902. The middle part of the suspension trailer support lower arms 904 is connected to the support plate 1001. The suspension trailer support upper arms 902 and suspension trailer support lower arms 904 form a triangular arm structure on both sides of the support plate 1001. The suspension structure 100 is connected to the functional assembly trailer through the triangular arm structure on one side and to the core chassis vehicle through the triangular arm structure on the other side.

[0056] In this embodiment, the support plate 1001 is based on a circular shape and can be deformed as needed. It adopts a hollow radial rib structure design to reduce weight, and is combined with multiple crossbeams to achieve a suspension stability structure. It is connected to the functional assembly load trailer and the core machine platform box truck in a two-way triangular arm to achieve interlocking stability of the vehicle's distributed interconnection structure.

[0057] Combination Figure 6 As shown, connection holes 507 are provided at the four corners of the interface flange 504, and threaded holes (not shown in the figure) corresponding to the positions of the connection holes 507 are provided on the two first crossbeams 1002. The interface flange 504 is fixedly connected to the first crossbeam 1002 by bolts through the connection holes 507, so as to achieve fixed support and constrain the impact displacement of the duct operation.

[0058] The second crossbeam 1005 and the third crossbeam 1007 provide support and displacement tracks for the upper support block 204 and the lower support block 205, and also serve to fix and connect the two support plates 1001. By setting multiple reinforcing plates 1003 between the two support plates 1001, multiple crossbeams can be fixed, and the entire suspension structure 100 forms a multi-segment structure with multiple combined reinforced load-bearing structures, which facilitates the layout of components.

[0059] The working principle of the present application is that the upper support block 204 and the lower support block 205 of the side spraying function module are respectively supported by the second cross beam 1005 and the third cross beam 1007 of the suspension structure 100, thereby realizing the installation of the side spraying function module on the suspension structure 100. The function module interface 50 is installed on the first cross beam 1002 of the suspension structure 100 through the interface flange 504.

[0060] In the present embodiment, after the side spraying function module determines the vector angle on the horizontal plane X-Y plane, the side spraying function module adjusts the horizontal plane vector through the through-pin connection of the long rectangular hole 105 of the upper support block 204 and the adjusting pin hole 505 on the interface flange 504; the axial fixing mode of the drainage pipe 10 adopts the X-shaped wedge block 70 and the lower matching block 603 to form a ratchet structure to support the drainage pipe flange 101, and the upper end of the X-shaped wedge block 70 is movably clamped through the upper matching block 502.
