Description

Technical Field

[0001] The invention relates to the technical field of car tipping machine equipment, and in particular to a novel double-spring unloading mechanism. Background Art

[0002] A car tipper is a large-scale mechanical equipment used to tip and unload bulk materials from railway open wagons. It is a loading and unloading machine that can flip or tilt rail vehicles to unload materials. It is widely used in ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. The car tipper pressing mechanism is a mechanical mechanism that fixes the train body during the tipping or tilting process of the car tipper. Existing car tipper pressing mechanisms generally use a simple hydraulic feed tightening method. After the tipping, the hydraulic system needs to work all the time, which not only increases energy consumption, but also reduces the service life of the hydraulic system. Once the hydraulic system fails, major accidents are very likely to occur. Summary of the invention

DETAILED DESCRIPTION

[0025] like Figure 1-6 As shown, a novel double spring unloading mechanism includes a base 1 and a bracket 2, wherein the base 1 is fixed on the cross beam, and the bracket 2 is rotatably connected to the base 1, an upper connecting beam 9 is provided on the outer side of the top of the bracket 2, and first bolts 11 are fixedly connected to the four corners of the top of the bracket 2, and the ends of the first bolts 11 pass through the guide holes provided on the upper connecting beam 9 and are screwed into the adjusting nuts 10, and a distance L is provided between the adjusting nuts 10 and the upper connecting beam 9, and the distance L can be adjusted by rotating the adjusting nuts 10.

[0026] A through hole is provided at the top center of the bracket 2, and an oil cylinder 3 is provided in the through hole. The bottom of the oil cylinder 3 is fixedly connected to the upper connecting beam 9, and the piston end of the oil cylinder 3 is hinged to the car pressing beam.

[0027] like Figure 4 As shown, the base 1 includes a bottom plate 101 fixedly connected to the cross beam by a second bolt, and two symmetrically arranged vertical plates 102 are fixedly connected in the vertical direction of the bottom plate 101, and a plurality of first reinforcing angle irons 105 are connected between the bottom plate 101 and the vertical plates 102. The vertical plates 102 are provided with connecting holes 103, and the outer sides of the connecting holes 103 are provided with gaskets 104, and the gaskets 104 are fixed to the vertical plates 102.

[0028] like Figure 5As shown, the bracket 2 includes a rectangular top plate 201 and two symmetrically arranged first connecting plates 202 connected in the vertical direction of the rectangular top plate 201, a plurality of second reinforcing angle irons 206 are connected between the rectangular top plate 201 and the first connecting plate 202, a pin 8 is connected to the end of the first connecting plate 202 away from the rectangular top plate 201, one end of the pin 8 passes through the connecting hole 103 and is rotatably connected to the second connecting plate 203, the second connecting plate 203 is connected to the first connecting plate 202 through a support plate 204, and the two rebound components are respectively placed on the outer sides of the two first connecting plates 202.

[0029] A reinforcing plate 205 is fixedly connected to the rear end of the bottom surface of the rectangular top plate 201 , and the first connecting plate 202 , the second connecting plate 203 and the supporting plate 204 are all connected to the reinforcing plate 205 .

[0030] Two mounting holes 12 symmetrically arranged for the vehicle are provided on the top of the bracket 2 and the upper connecting beam 9, and a rebound component is fixedly connected in the mounting hole 12. The rebound component includes a spring guide rod 6 fixedly connected in the mounting hole 12, and the end of the spring guide rod 6 is vertically threaded downward through the spring base 7 and then screwed into the nut 5.

[0031] like Figure 7-9 As shown, when the car pressing device is in the initial state, there is a certain distance L between the lower surface of the adjusting nut 10 and the upper connecting beam 9. During the operation of the car pressing device, the piston end of the oil cylinder 3 extends to push the car pressing beam and the car side to be pressed tightly. At this time, the spring 4 is in a relaxed state, and the distance L between the lower surface of the adjusting nut 10 and the upper connecting beam 9 remains unchanged. When the car pressing beam is released, the car pressing beam has a rebound L within a certain range. When the pressure of the oil cylinder 3 remains unchanged, the car pressing beam drives the oil cylinder 3, the upper connecting beam 9, the spring guide rod 6 and the spring base 7 to produce a rebound action L. At this time, the bracket 2 remains stationary, the upper surface of the spring 4 contacts the bracket 2 and remains stationary, and the lower surface of the spring 4 is compressed by the rebound pressure of the spring base 7. At this time, the spring 4 is in a compressed state. Under the joint action of the oil cylinder 3 and the spring 4, the car pressing beam and the car side in the released state still remain in a pressed state, and this action does not require the action of hydraulic equipment, thereby reducing energy consumption.
