The utility model provides a transport vechicle for snatch the skip from the storage bit, and then drive the skip and travel appointed place, so that the skip can dock with next station. The following describes preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, a schematic perspective view of a docking of a transportation vehicle 100 and a skip 200 according to an embodiment of the present invention is shown. Fig. 2 and 3 are a side view and a top view of the transporter 100 docked with the skip 200, respectively. As shown in the figures, the transportation vehicle 100 includes a body 10, and a docking mechanism 20 disposed on the body 10, wherein the docking mechanism 20 is configured to dock with a docking structure on the material vehicle 200, so as to provide a traction force to the material vehicle 200, so that the material vehicle 200 can move along with the transportation vehicle 100.
As described in the background art, the conventional transportation vehicle has a problem that the position error of the skip 200 cannot be effectively eliminated and the skip 200 cannot be accurately positioned when the skip 200 is grabbed by the conventional transportation vehicle.
In view of the above problems, an embodiment of the present invention improves the docking mechanism 20 of the transportation vehicle 100. As shown in fig. 4, fig. 4 is a schematic view illustrating the docking mechanism 20 and the skip 200 when the body 10 is not illustrated, the docking mechanism 20 includes a telescopic assembly 30, a lifting assembly 40 and a clamping device 50, wherein the telescopic assembly 30 is used for driving the lifting assembly 40 and the clamping device 50 to move away from or close to the body 10 (i.e., perform telescopic movement), the lifting assembly 40 is used for driving the clamping device 50 to ascend and descend in a vertical direction, and the clamping device 50 is used for docking with the skip 200.
Referring to fig. 3 and 4, the telescopic assembly 30 is disposed on the body 10, and is telescopic in a first direction, that is, the telescopic direction of the telescopic assembly 30 is defined as a first direction X. For convenience of description, the first direction X is also referred to as a front-rear direction hereinafter. The retraction assembly 30 has a retraction effect when in operation. In particular implementation, the telescopic assembly 30 may be capable of extending or contracting with respect to the body 10; or the retraction assembly 30 itself does not change in length, but it can be extended out of the body 10 or retracted into the body 10. In one example, the telescoping assembly 30 includes an electric telescoping pole 310.
A lift assembly 40 is provided on the retraction assembly 30. The lifting assembly 40 is used to drive the clamping device 50 to ascend and descend in the vertical direction. Thus, the telescopic assembly 30 can move the clamping device 50 back and forth relative to the body 10, and the lifting assembly 40 can move the clamping device 50 up and down in the vertical direction, so that the clamping device 50 can be docked with the docking structure.
As shown in fig. 3, 5 and 6, the clamping device 50 includes a supporting portion 510 for supporting the skip 200, a first blocking arm 520 and a second blocking arm 530 spaced apart from each other on two sides of the supporting portion 510 in a first direction, and two clamping arms 540 spaced apart from each other on two sides of the supporting portion 510 in a second direction, wherein the second direction is perpendicular to the first direction and parallel to the same reference plane. In one example, the first direction X and the second direction Y are both horizontal directions, and the reference plane is a horizontal plane. For convenience of description, the second direction Y is also referred to as a left-right direction. A positioning space is formed between the first blocking arm 520, the second blocking arm 530 and the two clamping arms 540, and the first blocking arm 520 and the second blocking arm 530 are used for limiting the swing amplitude of the skip 200 in the first direction X; the two clamping arms 540 are used for limiting the swing amplitude of the skip 200 in the second direction Y. In addition, when specifically arranged, two clamping arms 540 may be arranged on each side of the bearing part 510 at intervals along the second direction Y, so that the skip 200 can be better positioned from both sides in the left-right direction.
When the transport vehicle 100 and the skip 200 of the above embodiment are butted, referring to fig. 3 and 4, before the transport vehicle 100 is controlled to travel to the skip 200, the lifting assembly 40 lowers the clamping device 50 to the lowest point, the telescopic assembly 30 extends the lifting assembly 40 and the clamping device 50 and moves the clamping device 50 to the lower side of the butt structure of the skip 200, then the lifting assembly 40 drives the clamping device 50 to ascend, so that the carrying portion 510 holds the skip 200 from the lower side, meanwhile, the first blocking arm 520 and the second blocking arm 530 position the skip 200 from the front and rear direction, and the two clamping arms 540 position the skip 200 from the left and right direction, so that the front and rear directions and the left and right directions of the skip 200 are both limited, thereby eliminating the position error of the skip 200 and ensuring that the skip 200 can be accurately placed on the carrying portion 510. In addition, when the transport vehicle 100 travels, because the positioning constraints are added on the front and back and left and right directions of the skip 200, the skip 200 can be well prevented from shaking, the position of the skip 200 on the transport vehicle 100 is ensured to be accurate, and the difficulty in butt joint of the skip 200 and the next station is reduced.
In the above embodiment, after the clamping device 50 is completely abutted to the skip car 200, the telescopic assembly 30 can be retracted to make the skip car 200 close to the body 10, so that the center of gravity of the skip car 200 is closer to the center of gravity of the body 10 of the transport car 100, thereby reducing the risk of the skip car 200 tilting during the driving process of the transport car 100.
In addition, the transport vehicle 100 is provided with a scanning device (which may be regarded as a machine vision positioning system, not shown), before the clamping device 50 of the transport vehicle 100 is abutted to the skip 200, the scanning device can be used to determine the position of the transport vehicle 100, even if the transport vehicle 100 runs to a proper position, which is beneficial to quickly achieving the abutment between the clamping device 50 and the skip 200.
In order to allow the skip 200 to be conveniently seated against the bearing part 510 of the clamping device 50. As shown in fig. 5, in an embodiment, a first inclined surface 521 is disposed on a side of the first blocking arm 520 facing the second blocking arm 530, and the first inclined surface 521 is away from the bearing portion 510 and extends obliquely upward; the second blocking arm 530 is provided with a second inclined surface 531 at a side facing the first blocking arm 520, the second inclined surface 531 extends obliquely upward away from the bearing part 510, and the first inclined surface 521 and the second inclined surface 531 face each other and are spaced apart from each other. During specific setting, the first blocking arm 520 and the second blocking arm 530 are respectively arranged at two ends of the bearing part 510 in the first direction X and tilt upwards, so that a horn-shaped insertion opening with a large top and a small bottom is formed between the first inclined plane 521 and the second inclined plane 531, when the clamping device 50 vertically ascends, the first inclined plane 521 and the second inclined plane 531 play a role in guiding the skip car 200, so that the skip car 200 can smoothly enter the positioning space, and finally the skip car 200 is positioned between the lower end of the first inclined plane 521 (the end close to the bearing part 510) and the lower end of the second inclined plane 531 (the end close to the bearing part 510).
Similarly, in order to make the skip 200 conveniently lean against the bearing part 510 of the clamping device 50, as shown in fig. 6 and referring to fig. 3, in an example, the clamping arms 540 are provided with third inclined surfaces 541, the third inclined surfaces 541 extend obliquely upward away from the bearing part 510, and the third inclined surfaces 541 of the clamping arms 540 at two sides are arranged opposite to and spaced apart from each other. Similar to the inclined planes of the first blocking arm 520 and the second blocking arm 530, the third inclined planes 541 on the two clamping arms 540 form a trumpet-shaped insertion opening with a large top and a small bottom in the second direction Y, so that when the clamping device 50 vertically ascends to be in butt joint with the skip 200, the third inclined planes 541 on the two clamping arms 540 guide the skip 200, so that the skip 200 can smoothly enter the positioning space, and finally the skip 200 is positioned between the third inclined planes 541 on the two clamping arms 540.
Further, in an embodiment, the first blocking arm 520, the second blocking arm 530 and the two clamping arms 540 are provided with the inclined surface structures. Thus, when the clamping device 50 is butted with the skip car 200, the two sides of the skip car 200 in the front-back direction and the left-right direction are provided with the guiding structures, and the clamping device 50 and the skip car 200 can be butted more smoothly.
Referring to fig. 3 and 4, in an embodiment, the clamping device 50 includes two clamping assemblies 550, the two clamping assemblies 550 are disposed at intervals along the second direction Y, and each clamping assembly 550 is connected to the lifting assembly 40 and is driven by the lifting assembly 40 to ascend and descend in the vertical direction. The clamping assembly 550 includes a bearing area 551 for supporting the skip 200, a first blocking arm 520 and a second blocking arm 530 respectively disposed at two ends of the bearing area 551 in a first direction, a clamping arm 540 disposed at one end of the bearing area 551 in a second direction, and the two bearing areas 551 together form the carrying portion 510. That is, the middle of the supporting portion 510 has a notch.
In the above embodiment, each of the clamping assemblies 550 is provided with the first blocking arm 520 and the second blocking arm 530, and each of the clamping assemblies 550 can independently position the skip 200 in the front-rear direction. Each clamping assembly 550 is provided with only one clamping arm 540, and the clamping arms 540 of the two clamping assemblies 550 jointly position the skip 200 in the left-right direction.
In the above embodiment, the two independent clamping assemblies 550 are provided, so that the clamping device 50 can be better adapted to the bottom structure of the skip 200. For example, when other structural members are disposed at the central position of the bottom of the skip 200, the two independent clamping assemblies 550 may be butted against the skip 200 from the left and right sides of the skip 200 without being affected by the other structural members on the skip 200.
In one embodiment, the lifting assembly 40 includes a first lifting member 410 and a second lifting member 420, and two clamping assemblies 550 are coupled to the first lifting member 410 and the second lifting member 420, respectively. Like this two centre gripping subassemblies 550 are controlled independently respectively, when centre gripping subassembly 550 and skip 200 dock, can finely tune the position of any centre gripping subassembly 550 in real time according to the butt joint condition, both guarantee the butt joint effect, also reduced the unexpected risk of damaging of centre gripping subassembly 550 simultaneously. The specific type of the lifting member is not limited, and for example, it may be a linear motor whose mover is coupled with the clamping assembly 550.
In one embodiment, as shown in fig. 4, the number of the telescopic assemblies 30 is two, and the two telescopic assemblies are respectively used for driving the first lifting member 410 and the second lifting member 420 to be telescopic. Further, a stop 560 is disposed between the two retraction assemblies 30. The stop 560 is located on a side of the clamping assembly 550 proximate the body 10. The stopper 560 may allow the first lifting member 410 and the second lifting member 420 to be synchronously and stably extended and retracted; in addition, the stopper 560 also serves to limit the skip 200, and prevent the skip 200 from approaching the body 10 too much. In one example, the telescoping assembly 30 includes a telescoping pole 310, a support bracket 320 coupled to the telescoping pole 310. The lifting assembly 40 is mounted to the support bracket 320. The stop 560 is coupled between the two support brackets 320.
In one embodiment, as shown in FIGS. 5 and 6, clamp assembly 550 further includes a fixing portion 552, fixing portion 552 is connected to lift assembly 40, load bearing section 551 is connected to fixing portion 552, and clamp arm 540 is connected to both fixing portion 552 and load bearing section 551. Through the above measures, the clamping arms 540 have the function of positioning the skip car 200 on one hand, and the clamping arms 540 have the function of reinforcing ribs on the other hand, so that the clamping assembly 550 has better stability. In one example, the clipping arm 540 is a right-angled triangle, the right-angled end of the right-angled triangle is close to the load-bearing area 551, the beveled ends of the two right-angled triangles are slopes extending obliquely upward away from the load-bearing portion 510, the two beveled ends face each other, and the beveled end of the right-angled triangle forms the third bevel 541. In this example, the arm lock 540 is directly made of a right-angled triangular plate, which is easy to manufacture, and the bevel edge end of the right-angled triangular plate is directly used for positioning and guiding the skip 200, so that the skip 200 can be conveniently positioned in the left-right direction. In addition, the clamp arm 540 is not limited to be a right-angled triangular plate, and may be a polygonal slope having another shape, wherein one side of the polygonal slope is connected to the bearing region 551, the slope of the polygonal slope is away from the bearing portion 510 and extends obliquely upward, and the slopes at both sides face each other to form a limit for positioning the skip 200, so that the skip 200 can be guided into the positioning space and the skip 200 can be limited. For example, the clamping arms 540 may also be obtuse triangular plates, and the oblique sides of the obtuse angles of the obtuse triangular plates are slopes. For example, clamp arm 540 may be a quadrilateral or more polygonal plate, one side of which forms a ramp for guiding and restraining cart 200 when connected to load bearing area 551. The polygonal slope is not limited to a plate-like structure, and the above-described slope may be formed.
In one embodiment, as shown in fig. 4, the telescopic assembly 30 comprises a telescopic rod 310 and a support frame 320 connected to the telescopic rod 310. The supporting frame 320 is provided with a rail 321 arranged along the second direction X. The lifting assembly 40 is mounted to the support bracket 320. Each clamping assembly 550 is provided with a slider 553, the slider 553 being connected to a fixing portion 552 of the clamping assembly 550, the slider 553 being slidably connected with the rail 321. By the above means, when the lifting assembly 40 lifts the clamping assembly 550, the clamping assembly 550 moves more stably.
In order to solve the problem of transportation of the skip car 200 due to space limitation, in an embodiment, as shown in fig. 1, a groove 110 is formed on a surface of the body 10, the telescopic assembly 30 is disposed in the groove 110, and the lifting assembly 40 can extend out of or retract into the groove 110 under the driving of the telescopic assembly 30. When the telescopic assembly 30 retracts, the clamping device 50 drives the skip car 200 to be close to the body 10, and the skip car 200 at least partially enters the groove 110, so that the skip car 200 and the transport vehicle 100 form a whole, the space is saved, the problem that the transport of the skip car 200 is influenced by the limitation of the space is solved, the transport efficiency is improved, and the transport cost is reduced.
Further, the inner wall of the groove 110 is provided with a guide rail 120 disposed along the first direction X, and the guide rail 120 has a guide path extending along the first direction. The retraction assembly 30 further includes a chute 330 connected to the retraction rod 310. The chute 330 engages the rail 120. By providing the guide rail 120 and the sliding groove 330, the telescopic assembly 30 can smoothly drive the skip 200 into the groove 110.
