Furthermore, the lifting oil cylinder is additionally provided with a balance valve.
The utility model has the advantages that: (1) the utility model discloses reselect tipping platform atress fulcrum, change hard mechanism into laborsaving mechanism, greatly reduced its fault rate under the prerequisite of guaranteeing that the tipping platform can satisfy the work demand. (2) The utility model discloses change the installation of articulated round pin axle bed and earrings into screwed connection for welded fastening's permanent connected mode, avoided round pin axle earrings seat often not hard up, and the downthehole bush of round pin axle bed is not fragile. (3) The utility model discloses change the mechanical connection of knock pin seat into permanent welding, then lift cylinder top round pin axle seat welding seam position can not pull and split. (4) The manufacturing twist lock is repositioned, and the problems of left-right shaking and poor working stability during the lifting of the container are avoided. (5) The lifting oil cylinder is additionally provided with a balance valve, so that the danger that the tilting platform falls rapidly due to the fact that hydraulic oil of the oil cylinder leaks inwards is avoided. (6) The utility model discloses the reliability is guaranteed, and the fault rate is low, and cost of maintenance greatly reduced has great economic benefits.

Detailed Description
The parameters before the improvement of the sulfuric acid raw material tipping platform used in a certain plant are as follows:
the following is further described with reference to the accompanying drawings.
A sulfuric acid raw material tilting platform is transformed and installed in a certain factory according to the method, firstly, a tilting platform is manufactured independently, as shown in figure 3, the size of the original tilting platform is changed from 6.93 meters to 6.3 meters, and the actual calculation is 6.2 meters by considering the hinge connection and installation errors.
The overall structure of the tipping platform is shown in figure 2. The tipping platform main body support 1 and the tipping platform base 2 are welded, the lifting cylinder top pin base 5 is permanently welded on the tipping platform 6, the two rear parts of the rotary lock 8 are welded on the tipping platform 6, and the two front parts (one side close to the hopper) are movably installed. The lifting cylinder bottom pin seat 10 is fixed on the bracket 1 by a hinge, and the tipping platform base rear pin seat 9 is permanently fixed on the tipping platform base 2.
As shown in fig. 1 and 5, the current lift cylinder size and lift angle are continuously used, namely 60 °. The full extension c =4.75 m, the retraction length b =2.75 m, the inner diameter of the cylinder is 250mm, the lifting angle is 60 °, if the top end of the cylinder and the horizontal plane are set to be 30 °, c is a hypotenuse, b is a right-angled side to form a right-angled triangle, and a =3.87 m is pushed out. Taking into account the actual installation error, take a =3.85 meters. Because 3.1 is less than 3.85 is less than 6.2, the design is still a labor-saving mechanism, and the scheme is feasible.
Thus, the improved fulcrum location is: the distance of 2 m of the driving power arm is changed into 3.85m, the top end of the lifting oil cylinder and the horizontal plane form an included angle of 30 degrees, and the coordinates of the lower support of the oil cylinder (1.47 m, 1.375 m) are changed.
The power of the power arm at the position of 3.85m is 33.5 multiplied by 3.1/3.85=26.97(t), and the lifting force F of the oil cylinderGeneral assembly= PA =13 × 106 × 0.0625/4 × 3.14, derived from FGeneral assembly=63.78 (t). Pushing F because the top end of the lifting oil cylinder forms an included angle of 30 degrees with the horizontal planeVertical component=SIN30°×FGeneral assemblyAnd =63.78 × 0.5=31.89 (t), and since 31.89(t) > 26.97(t), the vertical lifting component force of the lifting oil cylinder at 3.85 meters meets the requirement.
The installation of the hinge pin shaft seat and the lug ring is changed into a permanent connection mode of welding and fixing, so that the phenomena of damage of a bush, pulling crack of a mother board of a connection part and the like caused by shearing of the connection part in the working process of the overturning platform are avoided.
The improved pin ejecting seat is a labor-saving mechanism, mechanical connection is changed into permanent welding, and the pin ejecting seat is reinforced.
Four twist locks were made for repositioning. The two parts at the rear side are fixedly arranged and used for positioning; the two pieces at the front side are movably arranged and used for locking and positioning the container. The lifting oil cylinder is additionally provided with a balance valve, so that the field use safety is ensured.
After the new overturning platform is transformed and installed, the operation is continuously and stably carried out for more than 430 days, and no fault occurs. Lifting is more convenient and labor-saving than before, the pin boss behind the tipping platform and the pin boss on the top of the lifting oil cylinder do not generate shearing deformation, after the twist lock is repositioned and installed, the condition that the container and the tipping platform are integrally lifted when the container is lifted away from an empty container does not occur, and the feedback use effect of field operators is good.
