Description

A kind of loading machine lateral unloading device
Technical field
The present invention relates to technical field of engineering machinery, more particularly to a kind of loading machine lateral unloading device.
Background technique
Major function equipment of the loading machine as development & construction such as civil construction, coal mine, iron ores, effect is self-evident, It, which is equipped with different accessory link mechanisms, can complete some special functional demands.Wherein coal mining, the operating conditions such as tunnel construction Since working space is narrow, loading machine can only be moved forward and backward, and to complete to shovel loading and unloading operation, side-discharging device comes into being.And mesh The preceding side dumping used in the market is all the front and back overturning and left and right overturning all crossed articulated structure and realize scraper bowl.Its construction profile figure is such as Shown in Fig. 1-2.When existing side-discharging device shovel dress, by taking the right side is unloaded as an example, a left side is unloaded hinged (scraper bowl and bracket) and is overlapped;It unloads hingedly on the right side The merga pass pin shaft connection of (scraper bowl and bracket) weight.
Scraper bowl 1 receives bucket after shoveling material, and pull rod pulls bracket 2 by pull rod hinged-support 6, makes scraper bowl around swing arm hinged-support 5 rotations are completed to receive bucket movement.Bracket unloads hinged-support 4 by the right side and transmits torque to scraper bowl during this.Weight, which is given rise to, to be unloaded After carrying height, scraper bowl unloads hinged-support rotation around the right side and completes discharging.Plane where A indicates scraper bowl mass center in Fig. 2 (and connecting rod machine Structure transmits torque ideal plane), when B indicates tipping bucket, where the position of comprehensive function power (material reaction and scraper bowl gravity) Plane.In real work, comprehensive function point of force application can not be located at B, and extreme case is located at A left side of face.When bucket is received in analysis, It is as shown in Figure 3 relative to 7 stress condition of pin shaft on comprehensive function power horizontal plane.F is comprehensive function power, and F1 is scraper bowl left and right directions Component, F2 scraper bowl front and back component.Therefore, pin shaft both direction all bending moments (shearing force), and with comprehensive function point in work Variation, moment of flexure size constantly changes.
It is not overlapped due to transmitting torque ideal plane A in link mechanism with plane B, driving device drives loading machine right Torque transmission efficiency when unloading is low.And since the face A is not overlapped with the face B, the right side unloads that unload hinged place stress condition with a left side complicated, is also easy to produce Fracture.If the right side is unloaded hinged place and is plastically deformed, a scraper bowl left side, which is unloaded, hingedly unloads hinged dislocation with a bracket left side, can make scraper bowl that can not return Position.Scraper bowl unloads hinged rotation around the right side, and the face scraper bowl right hand edge distance A is more and more closer, therefore unloads distance and shovel no more than original state Struggle against edge.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of loading machine lateral unloading devices, when can be improved side dumping Torque transmission efficiency;Avoid pin shaft hinged place forced breakage repeatedly.
The present invention adopts the following technical solutions, a kind of loading machine lateral unloading device, including scraper bowl and bracket, the bottom of the scraper bowl End is equipped with arc sliding portion, and the bracket is equipped with the arc-shaped guide rail being used cooperatively with arc sliding portion, and the scraper bowl is in arc It is slided under the drive of shape sliding part along the side of arc-shaped guide rail;Pull rod hinged-support is fixed in the middle part of the bracket, The pull rod hinged-support is fixedly connected with cylinder support, the end rotation connection of cylinder support and hydraulic cylinder, the hydraulic cylinder Piston rod is hinged with scraper bowl, and stretching for piston rod provides power for the sliding of scraper bowl in the hydraulic cylinder.
Further, the arc sliding portion includes two arc panels being fixedly connected with scraper bowl, and two arc panels are opposite Side is equipped with arc slippery fellow, and the both ends of the surface that the arc-shaped guide rail is away from each other are respectively equipped with sliding slot, and the arc slippery fellow is respectively set In sliding slot.
Further, the arc-shaped guide rail includes two guide rails disposed in parallel, passes through pull rod hinged-support in the middle part of two guide rails It is fixedly connected, swing arm hinged-support is also fixed between two guide rails, the swing arm hinged-support is symmetrically set about pull rod hinged-support It sets.
Further, the pull rod hinged-support and loading machine pull rod are hinged, the swing arm hinged-support respectively with loading arm Hingedly.
Further, the curved surfaces on the outside of the scraper bowl are fixedly connected by connecting plate with the arc panel.
Further, the scraper bowl lateral surface is equipped with piston rod bearing, the piston rod hinge of the piston rod bearing and hydraulic cylinder It connects.
Further, the cylinder support includes two support plates disposed in parallel, and one end of two support plates is equipped with pin hole, Two support plates are hinged by pin hole and hydraulic cylinder.
Compared with prior art, the beneficial effects of the present invention are:
1) present invention substituted using arc sliding portion and arc-shaped guide rail cooperation pin shaft it is hinged by the way of, the self weight of scraper bowl with And the gravity of material is shared by entire arc-shaped guide rail and arc sliding portion, effective contact area is bigger, unit in torque transmitting Pressure is small, when can be to avoid using single pin shaft, pin shaft repeatedly stress easily-deformable fracture the shortcomings that.
2) the ideal torque of arc sliding portion and arc-shaped guide rail transmits plane A (the i.e. equivalent substitution of scraper bowl and material gravity Plane) it is overlapped with torque actual transfer plane B (practical arc-shaped guide rail actual loading equivalent plane), torque transmission efficiency is higher.
3) when discharging rotates, bucket lip moves out trend, effective to increase unloading distance, in slag-soil truck and loads Machine keeps the unloading that material can be efficiently accomplished while certain distance.
