The indoor test mainly comprises asphalt mixture mix proportion design and performance verification of an asphalt mixture road in the production process, which is required to be matched with a pavement compaction mode of a construction site, so that the indoor test result can better guide site construction, the existing indoor asphalt mixture compaction is mostly realized by a Marshall compaction method, namely, a compaction hammer is lifted and lifted to a set height by a machine, so that the compaction hammer falls freely, and vibration and compaction work of the asphalt mixture are completed after the compaction process is repeated for a set number of times;
However, the marshall compaction method can only simulate the rolling process (vibration and compaction) of the asphalt mixture by the steel-wheel road roller, but cannot simulate the rolling of the asphalt mixture by the rubber-wheel road roller (the asphalt mixture has a certain rolling effect, namely, the asphalt mixture is subjected to vertical pressure and also to acting force along the direction opposite to the advancing direction of the vehicle, and the acting force is commonly called rolling pressure); the performance and strength of the test piece are also greatly different from those of the mixture compacted on site, so that the actual compaction condition of the pavement cannot be truly reflected;

Therefore, in the compaction process of the indoor asphalt mixture, the excitation and kneading actions are comprehensively considered, the manual operation of operators is reduced as much as possible, the compaction process of the site asphalt pavement is simulated as much as possible, relevant indoor test equipment is developed, and the experimental result can better guide the site construction.

Detailed Description
The foregoing and other features, aspects and advantages of the present invention will become more apparent from the following detailed description of embodiments of the present invention when taken in conjunction with the accompanying drawings, wherein like reference characters refer to the same parts throughout the several views.
Embodiment 1, this embodiment provides a simple and easy vibration compaction device in bituminous mixture room, as shown in fig. 1, including handling frame 1, the improvement of this scheme lies in: a plurality of circular frames 2 rotatably installed with the circular frames (the circular frames 2 are rotatably installed along the radial direction of the operation frame 1) are arranged on the operation frame 1 at intervals, positioning devices corresponding to the circular frames 2 are arranged on the operation frame 1, the specific structure of the positioning devices is described in detail in the following embodiments), test cylinders (which are circular) radially arranged along the circular frames 2 are installed at the positions passing through the center of the circular frames 2, as shown in fig. 6, two compaction plates 4 are vertically arranged on the circular frames 2 at intervals, the two compaction plates 4 and the test cylinders are coaxially arranged, as shown in fig. 16, contact plates 5 are vertically and slidably installed in the compaction plates 4, rubber pads 6 are arranged on the opposite sides of the two contact plates 5, as shown in fig. 11, the diameters of the two compaction plates 4 are smaller than the inner diameters of the test cylinders, the diameters of the contact plates 5 and the rubber pads 6 are the same as the inner diameters of the test cylinders, as shown in fig. 1, and initially, the circular frames 2 are positioned under the action of the positioning devices corresponding to the test cylinders (at this time, the test cylinders are positioned vertically;
When the device works, an operator can take out asphalt mixtures which are prepared in advance and have different proportioning relations from the heat insulation box and put the asphalt mixtures into corresponding test cylinders respectively, as shown in fig. 11, initially, two compaction plates 4 are respectively positioned at the upper end and the lower end of the test cylinders and are in a limited state under the action of the hydraulic control device, the asphalt mixtures put into the test cylinders are positioned between the two compaction plates 4, then the operator starts the compaction device to work, and then the compaction plates 4 in each circular frame 2 and above are vibrated and compacted, and in the process that the compaction plates 4 in each circular frame 2 and above are vibrated and compacted by the compaction device, the hydraulic control device can realize: limiting the lower compacting plate 4, when the compacting device acts on the upper compacting plate 4 and forces the upper compacting plate 4 to descend in the test cylinder (asphalt mixture in the test cylinder starts to be compressed under the acting force exerted by the compacting device), the hydraulic control device can drive the contact plate 5 matched with the lower Fang Yashi plate 4 to move upwards for a part of distance, namely, the compacting device acts on the upper compacting plate 4 to compact the asphalt mixture, simultaneously applies the hydraulic control device to the contact plate 5 corresponding to the lower Fang Yashi plate 4 to act upwards, and synchronously realizes the compaction of the asphalt mixture in the test cylinder (in the process, the lower compacting plate 4 is always in a positioned state under the action of the hydraulic control device), and each time the compacting device hammers the upper compacting plate 4, the hydraulic control device can drive the contact plate 5 corresponding to the lower Fang Yashi plate 4 to move upwards for a part of distance in the test cylinder (each time the moving distance is variable, and depends on the size of the moving downwards of the upper plate 4 each time the compacting device acts on the upper compacting plate 4);
As shown in fig. 9, a rotating device is respectively arranged at the upper end surface and the lower end surface of a test cylinder, the rotating device can drive a corresponding contact plate 5 to rotate in the test cylinder, a unidirectional transmission device connected with the two rotating devices is arranged on a circular frame 2, as shown in fig. 4, the unidirectional transmission device is connected with a transmission gear 7 rotatably arranged on an operation frame 1, the transmission gear 7 is driven by a bull gear 8 rotatably arranged on the operation frame 1, as shown in fig. 1, each circular frame 2 corresponds to one transmission gear 7 rotatably arranged on the operation frame 1, and a plurality of transmission gears 7 are driven by the bull gear 8 arranged on the operation frame 1, in the scheme, the bull gear 8 is driven by a rotating motor (not shown in the figure) and the bull gear 8 drives a compacting device, and when the device starts to work, namely, an operator controls a rotating motor to start to drive a bull gear 8 to rotate (further drive a compacting device to act and compact asphalt mixture in a test cylinder on each circular frame 2), simultaneously, a plurality of transmission gears 7 are synchronously driven to rotate along with the rotation of the bull gear 8, the transmission gears 7 rotate and are matched with a unidirectional transmission device to realize that two rotating devices are not simultaneously driven to act, namely, when the transmission gears 7 rotate under the drive of the bull gear 8, only one of the rotating devices can be driven to act through the unidirectional transmission device and a contact plate 5 corresponding to the rotating device is driven to rotate in the test cylinder, when the compacting device presses the upper end surface of a test piece, the rotating motor rotates positively and only can drive the contact plate 5 below to rotate in the test cylinder through the cooperation of the transmission gears 7 and the unidirectional transmission device, after the compaction of the upper end face of the test piece is completed, the operator releases the positioning device to position the circular frame 2 and rotates the circular frame 2 to 180 degrees (the positioning device is used for positioning the circular frame 2 again), then the rotating motor is controlled to rotate reversely, and the rotating motor still can only drive the lower contact plate 5 to rotate in the test cylinder under the cooperation of the transmission gear 7 and the unidirectional transmission device (the upper contact plate 5 can not rotate all the time in the whole compaction process);
Because the contact plate 5 at the lower part is always in a rotating state in the whole compaction process, when the compaction device is applied to the compaction plate 4 at the upper part, the contact plate 5 at the lower part is driven to move upwards under the action of the hydraulic control device, and the contact plate 5 is always in a rotating state, a certain degree of kneading effect (in the process, the contact plate 5 at the lower part moves upwards to have a certain degree of acting force along the vertical direction on the asphalt mixture) on the lower end surface of a test piece can be realized, namely, the acting force along the horizontal direction on the contact surface of the asphalt mixture and the rubber pad 6 is applied when the contact plate 5 rotates (the interaction force between the asphalt mixture and the rubber pad 6 is mainly expressed when the contact plate 5 drives the rubber pad 6 to rotate in a test cylinder), the contact position of the asphalt mixture and the rubber pad 6 can be subjected to the same size as the contact position of the contact plate, but the opposite direction of the contact position of the asphalt mixture is also subjected to the reaction force, the acting force directly generates a shearing effect on the asphalt mixture, so that asphalt mixture particles relatively move, the asphalt mixture particles can be conveniently combined in the horizontal plane along the rotating direction of the contact plate 5 to realize the recombination of particles with small particle size in the contact direction, and the asphalt mixture particles can be conveniently embedded into the test piece, and the asphalt mixture particles can be conveniently formed;
In the above process, the compaction device realizes vibration and compaction effects on the asphalt mixture by acting on the compaction plate 4 above, and the contact plate 5 below synchronously realizes kneading and pressing effects on the asphalt mixture to a certain extent, so that the asphalt mixture test piece fully imitates the road pressing process (namely, the steel wheel road roller and the rubber wheel road roller are matched for use) during real road construction in the manufacturing process, the manufacturing of the test piece is closer to the working procedure during real road construction, the quality of the manufactured asphalt mixture test piece is more fit with reality, and after the compaction of two end surfaces of the asphalt mixture test piece is completed and after the test piece is cooled, an operator takes the asphalt mixture test piece out of the test tube, and further the subsequent measurement process is completed.

When asphalt mixture is placed in the test cylinder, the two pushing plates 10 which are positioned at the same side and matched with the two pushing plates are in a position relation with the corresponding cylinder 11, as shown in an attached drawing 11, the cylinder 11, the connecting pipe 15 and the straight pipe 53 are filled with hydraulic oil, the corresponding electromagnetic valve 12 of the lower cylinder 11 is in a closed state (the electromagnetic valve 12 corresponding to the upper cylinder 11 is in an open state, namely, the upper cylinder 11 is communicated with an oil storage tank), the lower compacting plate 4 is in a limited state under the action of hydraulic oil in the lower cylinder 11 (the pressing of the asphalt mixture on the rubber pad 6 below can not cause the compacting plate 4 to move downwards), when the compacting device acts on the upper compacting plate 4, the upper compacting plate 4 is forced to move downwards in the test cylinder by a part distance, and then the pushing plate 10 connected with the U-shaped rod 9 is synchronously driven downwards in the corresponding cylinder 11, as shown in the attached drawing 11, the hydraulic oil in the upper cylinder 11 is compacted by the corresponding electromagnetic valve 12 under the action of the pushing plate 10, and the hydraulic oil is only moved downwards to the lower cylinder 11 by the corresponding to the electromagnetic valve 13, so that the hydraulic oil can always move downwards along with the upper compacting plate 11 in the unidirectional pressing plate 16 (the hydraulic oil is only can move downwards along with the electromagnetic valve 16 in the upper cylinder);
That is, at this time, the hydraulic oil in the upper cylinder 11 and under the push plate 10 enters the cavity 13 in the lower compacting plate 4 through the straight pipe 53, the force-accumulating check valve 16 and the connecting pipe 15, as shown in fig. 12, the valve plate 14 slidably mounted in the compacting plate 4 moves in the cavity 13 with the entry of the hydraulic oil into the cavity 13, thereby realizing that the lower contact plate 5 is driven to move up (at the beginning of the setting, the valve plates 14 in the two compacting plates 4 are in a contracted state, that is, the distance between the contact plate 5 and the corresponding compacting plate 4 is closest and no hydraulic oil exists in the two cavities 13), at this time, the compacting plate 4 under the moment is also subjected to the acting force exerted by the compacting device, but under the action of the hydraulic oil in the lower cylinder 11 (at this time, the valve plate 12 of the lower cylinder 11 is closed, so that the upper compacting plate 4 cannot move down), the upper compacting plate 4 is driven to move down by a certain distance in the mould cylinder with the compacting device hammering the upper compacting plate 4 and reaches the set number of times, and the contact plate 5 under the condition is made to move up in the mould, the distance corresponding to the upper cylinder 5 and the end face of the upper compacting plate is required to be adjusted relative to the end face of the upper end face of the test piece 10 in the upper cylinder 10, and the end face of the test piece is required to be adjusted by the mixing test piece is controlled by the following the end face of the test piece 10 in the upper end face of the test plate and the test plate is adjusted by the test plate (the end face of the test plate is required to be adjusted by the end face of the test machine;
That is, the operator manually rotates the circular frame 2 by 180 ° to complete the position exchange (at this time, the compacting plate 4 originally below is transferred to the upper side, and the compacting plate 4 originally above is transferred to the upper side), and the following steps: before adjusting the circular frame 2, the operator is required to close the solenoid valve 12 located above (i.e. both solenoid valves 12 located on the same side are closed at the moment), so that when the circular frame 2 is rotated and the solenoid valve 12 corresponding to the circular frame 11 located above is about to rotate 180 ° (when the solenoid valve 12 is not closed, the compaction plate 4 located above is subjected to the pressure of the test piece, the hydraulic oil in the upper cylinder 11 located above and above the push plate 10 is forced to flow back into the oil storage tank by the push plate 10, and further displacement of the compaction plate 4 is caused during adjustment of the circular frame 2), the solenoid valve 12 corresponding to the upper cylinder 11 is required to be closed first, when the circular frame 2 is adjusted by 180 ° (when the solenoid valve 12 corresponding to the circular frame 11 located above is located below), the operator is controlled to start the rotating motor again, when the compaction device starts hammering the compaction plate 4 located above (i.e. starts to compact the other end face of the test piece), the hydraulic oil in the cavity 13 located above (located above) enters the compaction plate 4) into the oil storage tank, and when the hydraulic oil in the compaction plate 4 is not in contact with the upper cylinder 4 is in the corresponding to the upper cylinder 13, and the compaction plate 16 is not in contact with the corresponding to the compaction plate 4 when the hydraulic oil in the upper cylinder 4 is in the corresponding mode, and the corresponding to the upper cylinder 4 is in the mode of the non-return device is in the mode when the compaction plate is in the mode shown, the contact plate 5 in the lower compacting plate 4 moves up a part of the distance (note: since the compaction of one end face of the asphalt mixture has been completed, the amount by which the asphalt mixture can be compressed decreases during compaction of the other end face, and thus the amount by which the upper compacting plate 4 moves down in the test cylinder decreases at this time and the amount by which the contact plate 5 in the lower compacting plate 4 moves up also decreases at this time);
With the action of the compaction device, until the set compaction times are completed (the test piece of asphalt mixture with certain compactness is obtained), the compaction operation of the test piece is completed, and then a plurality of test pieces can be taken out from the test cylinder after being cooled for a certain time.
In the embodiment 3, on the basis of the embodiment 2, as shown in fig. 11, a telescopic spring 17 is connected between a contact plate 5 and a compaction plate 4 corresponding to the contact plate, when hydraulic oil does not enter a cavity 13 in the beginning, the contact plate 5 is in a contracted state (namely, the distance between the two contact plates 5 is farthest at the moment) under the action of the telescopic spring 17, as shown in fig. 11, a channel 18 which is communicated with the cavity 13 is arranged in a U-shaped rod 9, the other end of the channel 18 is communicated with one end of a connecting pipe 15 which is arranged in a cylinder 11 (the channel 18 is not communicated with the cylinder 11, the channel 18 which is arranged in the U-shaped pipe is in sliding fit contact with the connecting pipe 15 which is arranged in the cylinder 11 at one end of the cylinder 11), when a compaction device acts on the compaction plate 4 which is arranged above, the compaction plate 4 is further forced to compress asphalt mixture downwards and move downwards in a test cylinder, and simultaneously drives a push plate 10 to move downwards in the corresponding cylinder 11, so as to realize that hydraulic oil which is arranged at the upper cylinder 11 and is arranged at the lower end of the push plate 10 is communicated with one end of the connecting pipe 15 in the cylinder 11, the connecting pipe 11, the hydraulic oil is conveyed to the one-way valve 16 to the lower end of the connecting pipe 15 through a straight pipe 53 which is arranged at the lower end of the compaction plate 10 and the compaction plate is arranged in the corresponding cylinder 11, and finally, the compaction plate is arranged at the distance is arranged in the cylinder, and the upper part of the compaction plate 4 is arranged in the cylinder, and the compaction plate 4, and is shown in the space, and the contact plate is in the space;
The force accumulation check valve 16 comprises a rectangular cavity 19 connected between a straight pipe 53 and a connecting pipe 15, as shown in fig. 13, an incomplete sphere 20 is vertically slidably arranged in the rectangular cavity 19, and a hemispherical body 22 is vertically slidably arranged in the incomplete sphere 20, as shown in fig. 12, when the compaction device does not work, under the action of a corresponding one-way spring 21, the incomplete sphere 20 tightly abuts against the position where the straight pipe 53 is communicated with the rectangular cavity 19, where the force accumulation check valve 16 at the outer side can only enable hydraulic oil to flow downwards from top to bottom, as shown in fig. 12, the force accumulation check valve 16 at the inner side can only enable hydraulic oil to flow downwards from top to bottom, and particularly, as shown in fig. 12, when the pushing plate 10 in the upper cylinder 11 moves downwards and presses the hydraulic oil in the upper cylinder 11 downwards, when the compaction device acts on the upper compaction plate 4, as shown in fig. 13, a part of hydraulic oil breaks through the acting force of the unidirectional spring 21 on the incomplete sphere 20, so that the incomplete sphere 20 moves down in the rectangular cavity 19 (synchronously drives the hemisphere 22 to move down, so that the hemisphere 22 is no longer abutted against the position where the straight pipe 53 is communicated with the rectangular cavity 19), the force-accumulating one-way valve 16 is opened, and a part of hydraulic oil enters the connecting pipe 15 in the lower cylinder 11 through the force-accumulating one-way valve 16 (as shown in fig. 12), finally, the liquid medicine oil enters the cavity 13 in the lower compaction plate 4, the contact plate 5 moves upwards in the test cylinder and the contact plate 5 moves upwards and is always in a rotating state (the asphalt mixture test piece is kneaded to a certain extent from below);
When the other end face of the asphalt mixture test piece needs to be pressed, an operator adjusts the angle of the test cylinder, at the moment, the compaction plate 4 which is originally below is above (the compaction plate 4 which is originally above is below), the operator closes the electromagnetic valve 12 corresponding to the cylinder 11 which is below at the moment and opens the electromagnetic valve 12 corresponding to the cylinder 11 which is above, and then the compaction device starts to compact the other end face of the asphalt mixture test piece, and the injection: at this time, a certain amount of hydraulic oil is arranged in the cavity 13 in the upper compacting plate 4, when the compacting plate 4 is impacted by the compacting device, the hydraulic oil in the cavity 13 cannot flow back to the cylinder 11 below through the corresponding channel 18, the connecting pipe 15 and the straight pipe 53 due to the action of the storage check valve 16 (namely, when the compacting device impacts the compacting plate 4 above, the position of the contact plate 5 corresponding to the compacting plate 4 relative to the test cylinder cannot be changed);
after the compaction of the asphalt mixture test piece is completed and the asphalt mixture test piece is cooled, the asphalt mixture test piece is demolded (i.e. taken out of the test cylinder), then an operator needs to reset the device, i.e. move the contact plates 5 to the initial position again, at this time, the operator only needs to fully open the electromagnetic valves 12 corresponding to the cylinders 11 at the upper end and the lower end, then press the two contact plates 5 respectively (so that the two contact plates 5 move away from each other), and the hydraulic oil in the cavity 13 is refluxed back to the cylinder 11 where it was originally located, and then the hydraulic oil is injected: before the action is executed, an operator is required to drive the hemispheroids 22 to move downwards relative to the incomplete spheres 20 corresponding to the hemispheroids 22 through a driving device arranged on the rectangular cavity 19, namely, the hemispheroids 22 are contracted downwards into the accommodating cavities 23 corresponding to the hemispheroids, as shown in fig. 14, the hemispheroids 22 are not abutted against the positions of the straight pipes 53 communicated with the rectangular cavity 19, the force accumulation check valves 16 are in a bidirectional conduction state, as shown in fig. 12, when the operator presses the contact plates 5, hydraulic oil in the corresponding cavities 13 is forced to flow back into the cylinders 11 where the hydraulic oil is initially located through the corresponding channels 18, the connecting pipes 15, the force accumulation check valves 16 and the straight pipes 53, and because all the electromagnetic valves 12 are opened at the moment, when the hydraulic oil in the empty cavities 13 flows back into the cylinders 11 again, redundant hydraulic oil in the cylinders 11 flows back into the oil storage tanks corresponding to the corresponding electromagnetic valves 12 until the two contact plates 5 cannot be pressed continuously, and the hydraulic oil in the cavities 13 cannot move to the initial positions (resetting of the device is completed);
Note that: during the process of re-discharging the hydraulic oil in the cavity 13 to the cylinder 11, the position of the pushing plate 10 in the cylinder 11 is also changed, that is, the pushing plate moves towards the initial position, so that the two compacting plates 4 are synchronously reset, and then an operator controls the hemispheroids 22 to move upwards relative to the incomplete spheres 20 by the driving device to enable the hemispheroids to collide with the straight pipes 53 and the rectangular cavities 19 again, so that the force storage check valve 16 is restored to the unidirectional circulation state again.
In the embodiment 4, on the basis of the embodiment 1, as shown in fig. 6, the rotating device comprises a worm wheel ring 24 coaxially arranged with the test cylinder and rotatably installed at the upper end and the lower end of the test cylinder, as shown in fig. 11, arc plates (not numbered in the figure) rotatably installed at the upper end and the lower end of the test cylinder are integrally arranged at the two axial sides of the bottom of the worm wheel ring 24, circular grooves (not numbered in the figure) rotatably installed and matched with the arc plates are arranged at the upper end and the lower end of the test cylinder, limit rods 25 vertically slidably installed with the worm wheel ring 24 are arranged at the two axial sides of the contact plate 5 (when the worm wheel ring 24 rotates, the contact plate 5 can be synchronously driven to rotate relative to the compacting plate 4 through the limit rods 25, and sealing rings are required to be arranged at the rotation installation positions of the contact plate 5 and the compacting plate 4 so as to prevent hydraulic oil entering into the cavity 13 from leaking outwards), and when the compacting plate 4 moves vertically relative to the test cylinder under the action of the compacting device, the limit rods 25 are always vertically slidably matched with the worm wheel ring 24, so that power transmission can be realized regardless of where the compacting plate 4 is located;
As shown in fig. 9, we rotate and install worm 26 respectively matched with two worm wheel rims 24 on circular frame 2, first unidirectional gears 27 are installed on the same sides of two worm 26 respectively, and two first unidirectional gears 27 are engaged with transmission gear 7, as shown in fig. 5, the rotation center of transmission gear 7 coincides with the center of circular frame 2 when set, when large gear rim 8 drives transmission gear 7 to rotate, it can only drive worm 26 matched with one first unidirectional gear 27 to rotate, that is, when rotating motor forward rotates, it can drive worm 26 corresponding to it through first unidirectional gear 27 located below to rotate (idle between first unidirectional gear 27 located above and worm 26 corresponding to it at this moment), when circular frame 2 adjusts 180 DEG, rotating motor reverse rotates, it can still drive worm 26 corresponding to it only through first unidirectional gear 27 located below (originally located above), that is, forward and reverse rotates, by setting rotating motor, it can only drive worm 26 located below when circular frame 2 is located in initial state or 180 DEG, it can realize that can drive worm 26 located below to rotate, it can realize rolling and rolling to mix asphalt pavement in opposite directions, it can realize rolling and rolling to mix the end face of asphalt pavement in the opposite directions, and mix the rolling mill 5, and mix the road roller is well in the opposite directions, and mix the rolling direction is realized, the manufacturing process of the asphalt mixture test piece is more attached to the compaction process in the actual road construction process).

In embodiment 6, on the basis of embodiment 1, as shown in fig. 1, the compacting device includes compacting rods 31 vertically slidably mounted on the operation frame 1 and matched with the circular frames 2, each circular frame 2 corresponds to one compacting rod 31 (the compacting rods 31 can only vertically move on the operation frame 1), when the rotating motor is started, the large gear ring 8 drives the steering device to act and the steering device drives the lifting device arranged on the operation frame 1 to act (the steering device acts in such a way that the lifting device can be driven to operate in the same direction no matter whether the rotating motor positively rotates or reversely rotates), and the lifting device further drives a plurality of compacting rods 31 to vertically reciprocate at corresponding frequencies, specifically:
Under the action of the direction adjusting device, the lifting device drives the inverted T-shaped rods 35 to do reciprocating lifting movement in the vertical direction, and as the abutting rods 32 integrally connected with the compaction rods 31 are abutted against the upper end surfaces of the circular rings 33, the inverted T-shaped rods 35 synchronously drive a plurality of compaction rods 31 to do lifting reciprocating movement in the vertical direction when doing reciprocating lifting in the vertical direction;
In this scheme, when elevating gear drives ring 33 to the highest point that moves, elevating gear no longer exerts ascending effort (elevating gear begins to move down) to ring 33, and then ring 33 can move down under the effect of conflict spring 34, and then make a plurality of compaction poles 31 synchronous downwardly move (so that compaction pole 31 bottom hammering is when being in the compaction board 4 of top, realizes vibration, compaction effect to the bituminous mixture), we set up the arc hole groove (not numbered in the figure) that is used for compaction pole 31 to pass on circular frame 2 for compaction pole 31 can enter into circular frame 2 and act on compaction board 4.

The specific process is as follows: when the lifting plates 38 on the two belt pulley sets 36 move to the position shown in fig. 3, at this time, the upper end surfaces of the two lifting plates 38 are abutted against the lower end surfaces of the inverted T-shaped rods 35, and with the continued operation (opposite operation direction) of the two belt pulley sets 36, the two lifting plates 38 are driven to move upwards to further drive the ring 33 to move upwards, and with the lifting of the inverted T-shaped rods 35, the two lifting plates 38 are synchronously lifted, and due to the two sloping plates 41 respectively arranged on the operating frame 1, the lifting plates 38 are gradually forced to retract inwards towards the corresponding mounting plates 37 under the cooperation of the arc-shaped protrusions 40 and the sloping plates 41, i.e. the contact area between the lifting plates 38 and the inverted T-shaped rods 35 is gradually reduced, so that when the lifting plates 38 are no longer in contact with the bottoms of the inverted T-shaped rods 35 (at this time, the plurality of compacting rods 31 are lifted to the height of the set positions, when the arc-shaped protrusion 40 is no longer in contact with the inclined plate 41, the lifting plate 38 retracted into the mounting plate 37 is ejected outwards under the action of the lifting spring 39, at this time, the ring 33 starts to move downwards under the action of the abutting spring 34 (meanwhile, the compacting rods 31 synchronously move downwards under the action of gravity so as to act on the compacting plates 4 to realize vibration and compaction of the asphalt mixture), when the inverted-T-shaped rod 35 falls to the initial position, the other lifting plate 38 mounted on the belt pulley group 36 is not moved to a position in contact with the lower end face of the inverted-T-shaped rod 35 along with the belt pulley group 36 (when the inverted-T-shaped rod 35 falls to the initial position, the other lifting plate 38 is contacted with the lower end face of the inverted-T-shaped tube after a small time, when the other lifting plate 38 is contacted with the inverted-T-shaped rod 35, the inverted-T-shaped rod 35 is driven upwards again, and then the process is the same, so as to complete the vibration and compaction process of the asphalt mixture.
In the embodiment 8, on the basis of the embodiment 7, as shown in fig. 3, the steering device comprises a rotating shaft 44 which is driven by a bull gear 8 and is rotatably mounted on an operation panel (the bull gear 8 drives the rotating shaft 44 to rotate through a gear meshed with the bull gear, the gear is not numbered in the figure), a second unidirectional gear 45 and a third unidirectional gear 46 are vertically arranged on the rotating shaft 44 at intervals, and when the rotating shaft 44 rotates, only one unidirectional gear is simultaneously driven to rotate (idle rotation is generated between the other unidirectional gear and the rotating shaft 44, namely, the mounting positions of the two unidirectional gears relative to the rotating shaft 44 are opposite), as shown in fig. 3, the second unidirectional gear 45 is meshed with an intermediate gear 48, the intermediate gear 48 is meshed with an output gear 47, and the third unidirectional gear 46 is meshed with the output gear 47;
When the bull gear 8 is driven by the rotating motor to rotate forward, the rotating shaft 44 is driven to rotate forward synchronously, the rotating shaft 44 is set to drive the second unidirectional gear 45 to rotate clockwise (the rotating shaft 44 can not drive the third unidirectional gear 46 to rotate) as shown in fig. 3, the second unidirectional gear 45 drives the intermediate gear 48 to rotate anticlockwise, the intermediate gear 48 drives the output gear 47 to rotate clockwise, and the output gear 47 transmits power to the cam belt group 43 to drive the cam belt group 43 to rotate;
When the ring gear 8 is rotated reversely under the drive of the rotating motor, the rotating shaft 44 is driven synchronously to rotate reversely, at this time, the rotating shaft 44 can drive the third unidirectional gear 46 to rotate and rotate in the anticlockwise direction shown in fig. 3 (the rotating shaft 44 can not drive the second unidirectional gear 45 to rotate), the third unidirectional gear 46 drives the output gear 47 meshed with the third unidirectional gear 46 to rotate in the clockwise direction, and the output gear 47 drives the cam belt group 43 to rotate, so that the rotation of the output gear 47 in the clockwise direction can be realized no matter the ring gear 8 rotates positively or reversely (i.e. the cam belt group 43 is ensured to always rotate in the same direction);
note that: when the bull gear 8 rotates the rotating shaft 44 in the forward direction, that is, the second unidirectional gear 45 rotates clockwise, at this time, the output gear 47 also rotates clockwise, the output gear 47 also drives the third unidirectional gear 46 meshed with the output gear 47 to rotate counterclockwise, that is, at this time, the rotating shaft 44 rotates clockwise, and the third unidirectional gear 46 rotates counterclockwise, because the rotating shaft 44 cannot drive the third unidirectional gear 46 in the clockwise direction (at this time, the rotation relationship between the third unidirectional gear 46 and the rotating shaft 44 is equivalent to the rotation of the rotating shaft 44 in the clockwise direction), the rotation of the rotating shaft 44 is not hindered by the third unidirectional gear 46 at this time (at this time, the rotation speed of the rotating shaft 44 is the same as that of the third unidirectional gear 46), and also when the bull gear 8 rotates the rotating shaft 44 in the reverse direction, the second unidirectional gear 45 is driven by the intermediate gear 48 to rotate in the opposite direction to the rotation of the rotating shaft 44, and the rotation of the second unidirectional gear 46 is not mutually interfered, and the structure related to the second unidirectional gear 46 is not described in the prior art (can be realized by the cooperation of the gears and the unidirectional bearings).
