Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict.
Example one
As shown in fig. 1, 2, 3, 4, 5, 6 and 7, the material trolley of the embodiment of the present application includes:
a frame 110;
a hopper 200 disposed above the frame 110;
a belt-throwing conveying mechanism 400 arranged above the frame 110;
the longitudinal moving mechanism 300 is positioned between the hopper 200 and the polishing belt conveying mechanism 400 and is respectively connected with the hopper 200 and the polishing belt conveying mechanism 400; wherein, the longitudinal moving mechanism 300 is used for driving the casting belt conveying mechanism 400 to move in the longitudinal direction above the frame 110, so that the casting belt conveying mechanism 400 extends and retracts relative to the frame 110;
the polishing belt 500 is installed on the polishing belt conveying mechanism 400, and the polishing belt conveying mechanism 400 is used for conveying the polishing belt 500.
According to the material vehicle provided by the embodiment of the application, the hopper is arranged above the vehicle frame, namely the vehicle frame is an installation foundation of the hopper, and the throwing belt conveying mechanism is arranged on the vehicle frame. The longitudinal moving mechanism is positioned between the hopper and the polishing belt conveying mechanism and is respectively connected with the hopper and the polishing belt conveying mechanism, namely the longitudinal moving mechanism is arranged between the hopper and the polishing belt conveying mechanism, so that the space between the hopper and the polishing belt conveying mechanism is effectively utilized, and the material vehicle is compact in structure. The hopper is an installation foundation of the longitudinal moving mechanism, is a basic structural member and bears the weight of the whole longitudinal moving mechanism. As the throwing belt is arranged on the throwing belt conveying mechanism, the longitudinal moving mechanism drives the throwing belt conveying mechanism to move in the longitudinal direction above the vehicle frame, so that the throwing belt also moves in the longitudinal direction above the vehicle frame to extend and retract relative to the vehicle frame in the process of extending the throwing belt conveying mechanism out of the vehicle frame. Therefore, when the material vehicle needs to carry out ballast material throwing work, the throwing belt and the throwing belt conveying mechanism can extend out relative to the vehicle frame, and the throwing belt carries out throwing work; when the material vehicle does not need to carry out ballast material throwing operation, the throwing belt and the throwing belt conveying mechanism can be retracted relative to the vehicle frame. According to the material vehicle, the hopper is used as a basic structural component, the hopper is an installation foundation of the longitudinal moving mechanism, and the longitudinal moving mechanism is installed between the hopper and the throwing belt conveying mechanism, so that on one hand, the space between the hopper and the throwing belt conveying mechanism is effectively utilized, the material vehicle is compact in structure and applicable to a working environment with a small space, and on the other hand, when the material vehicle needs to carry out ballast material throwing operation, the throwing belt conveying mechanism and the throwing belt are driven to extend out of the vehicle frame to throw ballast materials; when the throwing operation is not carried out, the throwing belt conveying mechanism and the throwing belt are driven to retract relative to the frame.
Specifically, the longitudinal direction is the traveling direction of the material vehicle, and the direction perpendicular to the traveling direction of the material vehicle is the transverse direction.
In practice, as shown in fig. 5, 6, 7, 8 and 9, the longitudinal moving mechanism includes:
an inverted U-shaped fixing base 310, a lateral portion of the fixing base 310 being installed at a lower end of the hopper 200; the transverse part of the fixing seat 310 is provided with a fixing seat through hole, and the lower discharge hole of the hopper 200 is communicated with the fixing seat through hole;
two longitudinal movement driving devices 320, which are relatively fixed at the outer sides of the two vertical portions of the fixing base, and the output shaft of the longitudinal movement driving device 320 extends into between the two vertical portions of the fixing base 310;
two longitudinal movement output gears 331, one of the longitudinal movement output gears 331 being mounted on an output shaft of one of the longitudinal movement driving means 320;
two longitudinal moving racks 332 respectively fixed on both sides of the tape-throwing conveying mechanism 400, wherein the longitudinal moving racks 332 are engaged with the longitudinal moving output gear 331;
the output shafts of the two longitudinal movement driving devices 320 rotate synchronously, and the belt-throwing conveying mechanism 400 is driven to move on the frame 110 along the longitudinal direction through the transmission of the longitudinal movement output gear 331 and the longitudinal movement rack 332.
The transverse part of the fixing seat is arranged at the lower end of the hopper, the lower discharge port of the hopper is communicated with the fixing seat through hole, so that ballast materials in the hopper can fall onto the throwing belt of the throwing belt conveying mechanism through the lower discharge port of the hopper and the fixing seat through hole, and the materials are conveyed and thrown through the throwing belt. In order to realize the movement of the throwing belt conveying mechanism and the throwing belt in the longitudinal direction, one longitudinal movement output gear is arranged on an output shaft of one longitudinal movement driving device. Two longitudinal moving racks are respectively fixed on two sides of the belt throwing conveying mechanism, and the longitudinal moving racks are meshed with the longitudinal moving output gear. Therefore, the two longitudinal movement driving devices synchronously rotate, and the belt throwing conveying mechanism is driven to move on the frame along the longitudinal direction through the transmission of the longitudinal movement output gear and the longitudinal movement rack. Thus, the longitudinal movement of the belt-throwing conveying mechanism is realized.
Specifically, as shown in fig. 8, the inverted U-shaped fixing seat 310 has a structure, and the size of the inverted U-shaped opening of the fixing seat 310 is matched with the width of the belt-throwing conveying mechanism, i.e. the transverse dimension of the fixing seat is determined by the transverse dimensions of the belt-throwing and belt-throwing conveying mechanisms.
For a working environment with a small space, the material vehicle with the small transverse direction of the throwing belt and the throwing belt conveying mechanism is selected.
Specifically, the longitudinal movement output gear is used for synchronously transmitting the torque output by the longitudinal movement driving device.
The transmission of motion between the longitudinal movement driving device and the belt throwing conveying mechanism is realized through the matching of the longitudinal movement output gear and the longitudinal movement rack, namely, the transmission is carried out through the matching of the gear and the rack, so that the motion can be stably transmitted.
Specifically, the longitudinal moving racks are fixed on two sides of the belt polishing conveying mechanism through bolts.
The longitudinal moving rack can be conveniently fixed through the bolt.
In an implementation, as shown in fig. 6 and 10, the longitudinal moving mechanism further includes:
two rear rollers 341, oppositely disposed at the outer bottom of the belt-polishing conveying mechanism 400 and far away from the fixed seat 310, wherein the rear rollers 341 are used for supporting the belt-polishing conveying mechanism 400;
two rear rails 342 fixed on the frame 110 and respectively carrying two rear rollers 341;
wherein the rear roller 341 moves along the rear rail 342 when the belt-throwing conveying mechanism 400 moves in the longitudinal direction.
When the belt polishing conveying mechanism does not move, the rear roller plays a supporting role on the belt polishing conveying mechanism; when the belt throwing conveying mechanism moves, the rear roller rolls along the rear guide rail, the rear roller plays a supporting role on the belt throwing conveying mechanism, and meanwhile, the friction force is small, so that the abrasion of the longitudinal movement output gear and the longitudinal movement rack is small.
In practice, as shown in fig. 5, 6 and 9, the longitudinal movement driving device 320 is located at the middle of the vertical portion of the fixed base 310.
Therefore, the position of the fixed seat relative to the longitudinal movement driving device is of a symmetrical structure, and the structure is symmetrical, so that the stress is balanced.
In an implementation, as shown in fig. 8, 9 and 10, the longitudinal moving mechanism further includes:
two pairs of inside rollers 351, wherein each pair of inside rollers 351 is oppositely arranged at the inner sides of the two vertical parts of the fixed seat 310, the two pairs of inside rollers 351 are symmetrically arranged relative to the longitudinal movement driving device 320, and the positions of the inside rollers 351 are higher than the longitudinal movement driving device 320;
two outer guide rails 352 respectively fixed at two outer sides of the tape-throwing conveying mechanism 400, wherein the two inner rollers 351 are respectively located at the two outer guide rails 352;
wherein the outer guide 352 and the inner roller 351 cooperate in a radial direction of the inner roller to define a longitudinal movement of the belt conveyor.
The position of the inner side roller is higher than that of the longitudinal movement driving device, so that the interference between the longitudinal movement rack and the outer side guide rail is avoided. In this way, the rear support of the polishing belt conveying mechanism is realized by the rear rollers and the rear guide rail, and the vertical bearing of the front part of the polishing belt conveying mechanism is realized by the inner rollers and the outer guide rail, so that the longitudinal movement output gear and the longitudinal movement rack are protected. The outer guide rail and the inner roller are matched in a mode, so that the longitudinal movement of the throwing belt conveying mechanism is limited by the outer guide rail in the radial direction, namely the vertical direction, of the inner roller. Therefore, the movement of the throwing belt conveying mechanism in the vertical direction is limited, and the situation of deviation in the vertical direction is reduced.
In an implementation, as shown in fig. 9, the longitudinal moving mechanism further includes:
two inner guide wheels 353, wherein the two inner guide wheels 353 are oppositely arranged at the inner sides of the two vertical parts of the fixing seat 310, and the positions of the inner guide wheels 353 are consistent with the height of the inner roller 351; the axial direction of the inner guide wheel 353 is perpendicular to the axial direction of the side roller 351;
the two inner guide wheels 353 are respectively located at the two outer guide rails 352, and the inner guide wheels 353 cooperate with the inner bottom surfaces of the outer guide rails 352 to limit the longitudinal movement of the belt conveyor 400 in the axial direction of the inner rollers 351.
The inner guide wheel rolls on the inner bottom surface of the outer guide rail when the tape-throwing conveying mechanism moves in the longitudinal direction above the carriage. The outer guide rail and the inner guide wheel are matched in a mode that the longitudinal movement of the throwing belt conveying mechanism is limited by the outer guide rail in the axial direction, namely the transverse direction, of the inner roller. Therefore, the inner side roller and the inner side guide wheel are matched with the outer side guide rail together, and the limit of the longitudinal moving direction of the belt throwing conveying mechanism is realized.
In practice, as shown in fig. 5, 6 and 10, the outer guide rail 352 is an outer guide rail 352 with a cross section of a shape of a letter [ e ], and the profile of the inner roller 351 is in contact with the inner profile of the upper wall and the lower wall of the outer guide rail 352;
the inner roller 351 is tapered in cross section, and the inner roller 351 can roll in the outer guide rail 352, so that the belt-throwing conveying mechanism 400 can obtain a good centering effect when moving longitudinally in the fixed seat.
The upper side wall and the lower side wall of the outer side guide rail limit the inner side roller in the radial direction of the inner side roller, the bottom wall between the upper wall and the lower wall of the outer side guide rail is in contact with the outer peripheral surface of the inner side guide wheel, and the bottom wall of the outer side guide rail limits the inner side guide wheel in the axial paying-off direction of the inner side roller, so that the inner side roller and the inner side guide wheel stably roll in the outer side guide rail, and the stable movement of the longitudinal movement direction of the belt throwing conveying mechanism is realized.
In implementation, the two vertical parts of the fixing seat are respectively provided with a through-going fixing seat through hole;
as shown in fig. 5, 8 and 10, the longitudinal moving mechanism further includes:
a pair of retraction position locking plates 361 fixed to the upper side of the tape-throwing transport mechanism 400, the retraction position locking plates 361 having retraction position locking plate through holes;
a pair of working position locking plates 362 fixed relatively above the sling transport mechanism 400 and behind the retracted position locking plate 361, the working position locking plates 362 having working position locking plate through holes;
two locking pins 363 respectively located at the two fixing seat through holes;
the two locking driving devices are fixed on the fixed seats and are respectively used for driving the two locking pins to move along the through holes of the two fixed seats;
when the belt throwing conveying mechanism is located at a retracting position, the retracting position locking plate through hole is overlapped with the fixing seat through hole, and the locking pin penetrates into the retracting position locking plate through hole to lock the position of the belt throwing conveying mechanism; when the belt throwing conveying mechanism needs to move longitudinally, the locking driving device drives the locking pin to withdraw from the through hole of the locking plate at the retraction position; when the belt throwing conveying mechanism moves to the working position locking plate through hole and the fixing seat through hole along the longitudinal direction to be overlapped, the locking driving device drives the locking pin to penetrate into the working position locking plate through hole to lock the position of the belt throwing conveying mechanism.
The belt throwing conveying mechanism comprises a fixing seat through hole, a withdrawing position locking plate through hole, a working position locking plate, a locking pin and a locking driving device which are matched, so that when the longitudinal moving structure moves to a preset working position in the longitudinal direction, namely the working position locking plate through hole and the fixing seat through hole are overlapped, the locking pin can penetrate through the fixing seat through hole and penetrate into the working position locking plate through hole, and the position of the belt throwing conveying mechanism relative to the fixing seat is locked. The limit position of the belt throwing conveying mechanism in the longitudinal direction is limited by the retraction position locking plate and the working position locking plate, and the condition that the belt throwing conveying mechanism moves excessively in the longitudinal direction is prevented.
In the implementation, as shown in fig. 1, 2, 3 and 4, the material trolley further includes:
the storage and transportation box 120 is fixed on the frame 110, and the hopper 200 is used for receiving ballast materials injected from a lower discharge port of the storage and transportation box 120;
a hopper bracket 130 fixed on the frame 110;
the end parts of two side arms of the U-shaped hopper mounting frame 140 are respectively rotatably connected with the hopper bracket 130, and the upper part of the hopper 200 is fixed on the inner side of the hopper mounting frame 140;
a lifting mechanism 600, the lower end of the lifting mechanism 600 is rotatably connected to the outer side of the transverse arm of the hopper mounting frame 140, and the upper end of the lifting mechanism 600 is rotatably connected to the storage and transportation box 120;
and the lifting driving device is used for driving the lifting mechanism to stretch in the vertical direction and driving the hopper to rotate around the hopper support to descend and lift.
The hopper is fixed on the inner side of the hopper mounting frame, the hopper mounting frame is rotationally connected with the hopper support fixed on the frame, and is rotationally connected with the storage and transportation box fixed on the frame through the lifting mechanism. Therefore, when the lifting driving device drives the lifting mechanism to contract in the vertical direction, the hopper integrally rotates upwards around the hopper support, and one side of the hopper connected with the lifting mechanism is lifted upwards. When the lifting driving device drives the lifting mechanism to extend in the vertical direction, the whole hopper rotates downwards around the hopper support, and one side of the hopper, which is connected with the lifting mechanism, is put down downwards.
Specifically, the lifting mechanism is a telescopic oil cylinder, and when the telescopic oil cylinder contracts upwards, the lifting mechanism drives the hopper and the belt throwing conveying mechanism to integrally rotate upwards; when the telescopic oil cylinder extends downwards, the hopper and the belt throwing transmission mechanism are driven to integrally rotate downwards.
Specifically, the upper end and the lower end of the lifting mechanism are rotatably connected, and the rotatable connection of the end parts of the two side arms of the hopper mounting frame is realized through hinging.
Specifically, when the ballast material is not thrown by the material trolley, the throwing belt conveying mechanism is retracted to the retraction position. In the withdrawing position, the throwing belt conveying mechanism is positioned between the storage box and the frame, the rear support of the throwing belt conveying mechanism is realized by the rear roller and the rear guide rail, and the front part of the throwing belt conveying mechanism is connected by the longitudinal moving mechanism, so that the throwing belt conveying mechanism is stably installed in the withdrawing position, and the safety of the whole material vehicle is high. Namely the throwing belt conveying mechanism is in a retracting position, and the problem of the lap of the throwing belt and the throwing belt conveying mechanism does not need to be considered.
In an implementation, as shown in fig. 9, the material trolley further includes:
an inner ring 710 of the slewing bearing is fixed with the outer side of the lower discharge port of the hopper 200, and an outer gear ring 730 of the slewing bearing is fixed with the fixed seat;
a rotation driving device 740;
a rotary output gear mounted on an output shaft of the rotary drive device 740 and engaged with the outer ring gear 730 of the slewing bearing;
the output shaft of the rotation driving device 740 rotates, and the rotation output gear and the outer gear ring 730 of the slewing bearing are driven to drive the outer gear ring 730 of the slewing bearing to rotate relative to the inner ring 710 of the slewing bearing, so that the fixed seat 310 can rotate relative to the lower discharge port of the hopper.
The inner ring and the outer gear ring of the slewing bearing are connected through the rolling body 720 of the slewing bearing, so that the outer gear ring of the slewing bearing can rotate relative to the inner ring of the slewing bearing, the inner ring of the slewing bearing is fixed with the outer side of the lower discharging opening of the hopper, and the outer gear ring of the slewing bearing is fixed with the fixed seat, so that the fixed seat can rotate relative to the hopper under the driving of the rotary driving device. The output shaft of the rotary driving device rotates, and the transmission is realized through the rotary output gear and the outer gear ring of the slewing bearing, namely, the transmission is realized through gear transmission, so that the fixed seat can rotate relative to the hopper, and further the whole belt-throwing conveying mechanism can rotate relative to the hopper.
Specifically, as shown in fig. 9, the outer ring gear 730 of the slewing bearing and the fixed seat 310 are fixed by bolts.
The mode of fixing the outer gear ring and the fixed seat of the slewing bearing through the bolts is simple and easy to realize, and the occupied space is small.
To sum up, the installation of this application embodiment's skip is realized through fixing hopper support and storage box on the frame, and the installation of skip is comparatively firm. The hopper is used as a basic structural member and is a mounting base of the longitudinal moving mechanism, the slewing bearing and the lifting mechanism, and the weight of the longitudinal moving mechanism, the belt throwing conveying mechanism, the slewing bearing and the lifting mechanism is borne, so that the longitudinal moving mechanism, the slewing bearing and the lifting mechanism are stably mounted. The longitudinal moving mechanism realizes the longitudinal movement of the polishing belt conveying mechanism, the slewing bearing realizes the rotation of the polishing belt conveying mechanism, and the lifting mechanism realizes the lifting of the polishing belt conveying mechanism, so that the longitudinal movement, the rotation and the lifting of the polishing belt are realized.
Specifically, the longitudinal movement driving device, the rotation driving device and the lifting driving device adopt hydraulic motors. The hydraulic motor can bear larger impact vibration and meet the harsh requirements of the use environment of the railway engineering machinery.
