Abstract
The utility model relates to the technical field of scraper conveyers, namely corollary equipment for machine gun combined mining on an underground coal mine working surface in a complex thin coal seam, and particularly to a middle groove of a scraper conveyer for machine gun combined mining. Firstly, the middle groove is low in height and can meet the requirements of thin coal seam matching; secondly, the middle groove is provided with a drift-preventing device, namely a short stroke cylinder with a slope regulating function is arranged on a transition side of the middle groove, so that the specific pressure of a ramp plate side to the ground is effectively increased; finally, the ramp plate groove side of the middle groove is provided with high intensity sharp saw-toothed rock breaking teeth. Moreover, a dump-preventing baffle plate with a guiding effect is arranged for a hydraulic drilling machine and on the middle groove.
Description
Technical field
The utility model relates to the technical field that girdle colliery mining face under mine machine gun connection is adopted corollary equipment drag conveyor, and specifically a kind of machine gun connection adopts the middle pan of scraper conveyor.
Background technology
Machine gun connection adopt be that balk, inclination angle in order to adapt to Southwestern China area is large and varied in thickness is large, dirt band and the many ground conditions of tomography, the reliability of equipment and compliance are required to all high characteristic and the coal-mining method that proposes.In this coal-mining method, hydraulic drill locomotive is walking automatically, perforating automatically on drag conveyor under hydraulic motor is controlled; Artificial explosion coal-falling; Employing hydraulic support carries out supporting, drag conveyor transports, and to improving coal production and the benefit of the complicated girdle in Southwestern China area, has great importance.Its corollary equipment is mainly comprised of hydraulic drill locomotive, hydraulic support, drag conveyor and peripheral matched equipment.For drag conveyor wherein, after explosion coal-falling, the work of coalingging need lean on hydraulic support to carry out the push-and-pull back and forth of drag conveyor, therefore need to study the performance of drag conveyor each side.Specifically, first require according to the height of the thickness reduction intermediate channel in coal seam.Secondly, when explosion coal-falling, a lot of coal cinders can drop between rib and intermediate channel, and this just requires intermediate channel ramp plate to have the good dress effect of shoveling coal, and change that original ramp plate structure is easily pricked the end when machine gun connection is adopted, resistance is large and effect of loading coal can not meet user demand.Need to the parameters such as shovel board obtuse angle, lower limb and overall structure be analyzed and researched and be designed, and increase the broken rock tooth of the sharp zigzag of high strength, make it meet the demand that machine gun connection is adopted.Support and hydraulic drill locomotive overturning-preventing that hydraulic support protects after coal plate puts down also need to be resolved in intermediate channel design details.
Summary of the invention
The purpose of this utility model is to adopt for adapting to machine gun connection a kind of machine gun connection employing the middle pan of scraper conveyor that coal-mining method designs.Its technical scheme is to reduce height, is provided with the anti-slip device that floats, and at it, passes the short stroke oil cylinder that side setting has oblique adjusting function; Be provided with the shovel board ledge with the broken rock tooth of zigzag; Also for hydraulic drill locomotive is provided with the overturning-preventing baffle plate with guide effect.
1) reduced the height of intermediate channel.Effectively guaranteeing, under intermediate channel and the intensity of scraper chain and the prerequisite in application life, the height of intermediate channel to be dropped to 220mm, to meet the requirement of the supporting mining height 1.6～2.2m of three machines.This intermediate channel all meets instructions for use through simulation calculation and ground experiment.
2) intermediate channel is provided with the anti-slip device that floats, and at it, passes the short stroke oil cylinder that side setting has oblique adjusting function.The effective travel of hydraulic cylinder is 50mm, and its cylinder bar is connected in gripper shoe by pin.When cylinder bar is regained, intermediate channel keeps flat on the ground; When cylinder bar stretches out, drive and have the action of the gripper shoe of rotating shaft, the passing side of intermediate channel is little by little raised and is at a certain angle with ground shape, has so just increased the specific pressure of intermediate channel ramp plate side to ground, reaches to prevent from floating to slip and the thorough effect of ground coal clearly.
3) intermediate channel is provided with the shovel board ledge with the broken rock tooth of zigzag.The broken rock tooth of this zigzag is to be made by high-strength abrasion-proof plate, and rock breaking capacity is strong, can greatly improve harp efficiency and transfer efficiency, has reduced the workload of manually coalingging.
4) intermediate channel is also that hydraulic drill locomotive is provided with the overturning-preventing baffle plate with guide effect passing side.It is parallel and keep certain gap that generally intermediate channel is passed the upper surface of side shield and hydraulic drill locomotive guide slip shoe, in the process of hydraulic drill locomotive perforating during because of the larger body run-off the straight of resistance, intermediate channel is passed side shield and can be carried out hydraulic drill locomotive guide slip shoe spacingly, prevents that body from toppling over.
In sum, intermediate channel whole height reduces, prevent floating the broken rock tooth shovel board ledge respective outer side edges use of slip device and zigzag and strengthened the effect of shoveling coal, also, for hydraulic drill locomotive is provided with the overturning-preventing baffle plate with guide effect, meet machine gun connection and adopt the structural requirement of corollary equipment to the middle pan of scraper conveyor.And the be designed with certain reference function of this mentality of designing to other intermediate channel for girdle corollary equipment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is that machine gun connection is adopted corollary equipment schematic diagram.
Fig. 2 is the anti-slip device schematic diagram that floats of intermediate channel.
Fig. 3 is the broken rock tooth schematic diagram of intermediate channel shovel board ledge zigzag.
In figure: 1. rib, 2. intermediate channel shovel board ledge, 3. intermediate channel is passed side deflector apron, and 4. hydraulic support protects coal plate, 5. hydraulic drill locomotive guide slip shoe, 6. short stroke hydraulic cylinder, 7. gripper shoe.
The specific embodiment
As shown in Figure 2, intermediate channel is anti-floats being mainly comprised of short stroke hydraulic cylinder 6 and gripper shoe 7 of slip device, and the two ends of short stroke hydraulic cylinder 6 are linked together by pin and intermediate channel and gripper shoe respectively.The stroke of this hydraulic cylinder is 50mm, and when cylinder bar is retracted, intermediate channel is passed side and kept flat on the ground.When hydraulic cylinder bar stretches out, drive gripper shoe action, the passing side of intermediate channel is little by little raised, and now the base plate of intermediate channel and ground shape are at a certain angle, as shown in the chain-dotted line profile in figure.So just increase the specific pressure of intermediate channel ramp plate side to ground, prevented from floating when slipping, strengthened the effect of clear ground coal.In addition, as shown in Figure 3, middle three teeth slightly protrude from the tooth at two ends to the profile of tooth of the broken rock tooth of the zigzag of the middle pan of scraper conveyor shovel board ledge 2, have strengthened the effect that broken rock is shoveled coal, and can also when support pushing and sliding, effectively clear up the residual coal cinder of base plate.
As shown in Figure 1, in the process of hydraulic drill locomotive perforating, during because of the larger body run-off the straight of resistance, intermediate channel is passed side deflector apron 3 can block hydraulic drill locomotive guide slip shoe 5, prevents that body from toppling over.
