Detailed Description
As shown in fig. 1 to 3, an embodiment of the present invention is a simple stone handling vehicle, which includes a main beam 1, a hanging stone beam 2, a wheel shaft 3, a wheel 4, a stand column 5 and two stone clamping devices; the hanging stone beam 2 is transversely arranged at the left end of the main beam 1, is mutually perpendicular to the main beam 1, is fixedly connected with the main beam 1 in the middle, and is provided with an operating handle 6 at the right end of the main beam 1, and the operating handle 6 is transversely arranged; the wheel shaft 3 is transversely arranged below the left side of the main cross beam 1, the wheels 4 are rotatably arranged at two ends of the wheel shaft 3, the upper end of the upright post 5 is fixedly connected with the main cross beam 1, the lower end of the upright post 5 is fixedly connected with the middle of the wheel shaft 3, and reinforcing ribs 7 are arranged between the upright post 5 and the main cross beam 1 as well as between the upright post 5 and the wheel shaft 3; the distance from the upright post 5 to the left end of the main beam 1 is less than the distance from the upright post 5 to the right end of the main beam 1; the stone clamping device comprises two cross rods 8 which are hinged with each other, wherein one ends of the two cross rods 8 are downwards and vertically fixedly provided with two clamping arms 9 made of steel materials, the two cross rods 8 and the two clamping arms 9 are symmetrically arranged by using hinge joints 10 of the two cross rods 8, the distance between the two clamping arms 9 is 2-5cm larger than the thickness of a stone 13, the other ends of the two cross rods 8 are connected with two lifting ropes 11, the other ends of the two lifting ropes 11 are obliquely and upwards connected with each other at the same angle, in order to ensure that the two clamping arms 9 have enough clamping force, the included angle between the two lifting ropes 11 is larger than or equal to 120 degrees, and the lower limit of the included angle of the two lifting ropes 11 is 120 degrees; the joint of the two lifting ropes 11 is upwards connected with a main lifting rope 12, and the upper ends of the main lifting ropes 12 of the two stone clamping devices are respectively fixedly connected with the two ends of the stone hanging beam 2; the length of the clamping arm 9 is less than half of the vertical distance from a hinge point 10 of the two cross rods 8 to the branch lifting rope 11, two stone clamping devices are arranged for stably clamping the stone sticks, and the two stone clamping devices are respectively arranged at two ends of the stone lifting cross beam 2.
When the carrying vehicle is used, the carrying vehicle is pushed to the side of a stone 13, two stone clamping devices are placed on the stone 13, the two clamping arms 9 of the stone clamping devices are separated by hands, the two clamping arms 9 are clamped on the stone 13, as shown in fig. 3, an operator stands at the position of an operating handle 6 and presses the operating handle 6 downwards, the left end of a main cross beam 1 tilts upwards to drive a main lifting rope 12 to be tensioned upwards, the main lifting rope 12 drives two lifting ropes 11 to be pulled upwards in an inclined mode, the branch lifting rope 11 pulls the two cross beams 8 to rotate around a hinge point 10, the two clamping arms 9 clamp the side faces of the stone 13, the stone 13 is taken away from the ground when the main lifting rope 12 is continuously lifted upwards, the operator can push the carrying vehicle to a destination, then the stone 13 is put down, the main lifting rope 12 and the branch lifting rope 11 are released, and the two clamping arms 9 are released. Because the distance between the upright post 5 and the left end of the main beam 1 is less than the distance between the upright post 5 and the right end of the main beam 1, the main beam 1 becomes a labor-saving lever, and an operator can lift the barred rock 13 more easily.
The mechanical principle of the stone clamping device for clamping the stone bars 13 is as follows:
as shown in fig. 4, when the barren rock 13 is lifted off the ground, the gravity G borne by the barren rock 13 must be smaller than the upward static friction force borne by the barren rock 13 by the clamping arms 9, since this embodiment is provided with two barren rock clamping devices, 4 clamping arms 9 in total, and if the static friction force of each clamping arm 9 is f, then:
G<4f ----①
and f = μ N- - - ②
Wherein N is the clamping force of a single clamping arm 9, and mu is the static friction factor.
NL2=F1L1 ----③
in the formula, L1 is the vertical distance from the hinge point 10 of the two clamping arms 9 to the branch lifting rope 11, i.e. the power arm; l2 is the vertical distance from the lower end of the clamping arm 9 to the hinge point 10 of the two clamping arms 9, i.e. a resistance arm; f1 is the pulling force of the branch lifting rope 11 to the cross bar 8.
If the included angle between the two lifting ropes 11 is α, the resultant force F of the pulling forces of the two lifting ropes 11 is:
F=sqrt(F12+F12+2·F1·F1·cos(α))= F1 ·sqrt(2+2cos(α)) ----④
where sqrt is squared on.
When the barred rock 13 is hoisted, the gravity of the clamping device, the main hoisting rope 12 and the branch hoisting rope 11 can be ignored, the upward pulling force of the clamping device is F, and the relationship between the pulling force of the two clamping devices and the gravity G of the barred rock 13 is as follows:
2F=G ----⑤
from the above formula ①②③④⑤:
L1/L2>0.5· sqrt(2+2cos(α))/μ
in this embodiment, the static friction factor μ between the steel clamping arm 9 and the stone is 0.6, and the included angle between the two lifting ropes 11 is 120 °, then: L1/L2>0.833, in this embodiment, the length of the clamping arm 9 is less than half of the vertical distance from the hinge point 10 of the two crossbars 8 to the branch lifting rope 11, i.e. L1/L2>2, which not only meets the above calculation result, but also has at least twice of safety factor, and can ensure that the clamping arm 9 has enough clamping force to clamp the barred rock 13.
The utility model discloses a main beam 1, hang stone crossbeam 2, shaft 3, wheel 4, stand 5 and press from both sides the stone device, can conveniently press from both sides and get the rectangular slab stone to the convenience transports the destination with the rectangular slab stone, and labour saving and time saving can improve work efficiency greatly.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention.
