Description
Technical field
The utility model relates to a kind of development machine chain jamming prevention device, belongs to engineering mechanical device technical field.
Background technology
Development machine is the machine for digging straight underground passage, and operating mechanism is broken rock on work plane, and the motion collection of the coal petrography of fragmentation by scraper plate fills by shipment activity, and runs to elevating conveyor by scratch board conveyor.Existing boom-type roadheader first conveyor is by the mode convey materials of scraper chain assembly, as shown in Figure 1, sprocket wheel 11 on bogie 10 drives scraper chain 12 to move along transporter chute 20, scraper plate sweeps the material on the upside of chute bottom plate 21, when transporting material, material is easily scattered in the gap of chute, the Transport resistance increasing scraper plate causes transporter to seize up, modal solution is reversed by the chain of transporter, owing to there is gap between bogie upper plate 13 and first conveyor chute bottom plate 21, the chain discontinuity on hydraulic motor both sides in motion process or due to problems such as installation accuracies, scraper plate is easily caused to be blocked by gap, there is chain jamming phenomenon, affect tunneler construction efficiency, dally over one's work progress.
Summary of the invention
For solving the problem, the utility model provides a kind of development machine chain jamming prevention device, occurs chain jamming when preventing the chain of development machine from reversing.
Technical scheme adopted to achieve these goals: a kind of development machine chain jamming prevention device, comprise bogie and transporter chute, chute bottom plate is positioned at the upside of bogie upper plate, and the tail end of described chute bottom plate has inclined plane, bogie upper plate has groove, and inclined plane stretches to the inside of groove.
When chain needs reversion, scraper chain assembly enters transporter chute along inclined-plane, sealing surface is formed between the tail end of chute bottom plate and bogie upper plate, gap plugging is lived, scraper chain assembly can not touch the gap between bogie upper plate and chute bottom plate completely, therefore there will not be the phenomenon of chain jamming.
Further, the inclined plane of chute bottom plate tail end is several helical teeth, and the groove on bogie upper plate is the teeth groove matched with helical teeth.In installation process, helical teeth is meshed with teeth groove, on the one hand improves assembly precision by location and installation, relative to the relative position of transporter chute, can improve the stability of equipment by bogie in limiting scraper transporter work process on the other hand.
Further, the transition face between the plane of chute bottom plate and inclined plane is circular arc.Prevent scraper plate from occurring clamping stagnation through inclined-plane.
Preferably, the angle of inclination on inclined plane is 15 ° to 30 °.
The utility model closes the sealing surface in gap by the cooperation composition between the inclined-plane of chute bottom plate and the groove of bogie upper plate, prevent scraper chain assembly to be stuck in gap, affect operating efficiency, and structure is simple, is convenient to install.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.For ease of describing, the left side of Fig. 2 is defined as front end, and right side is defined as tail end.
As shown in Figures 2 to 4, a kind of development machine chain jamming prevention device, comprise bogie 10 and transporter chute 20, chute bottom plate 21 is positioned at the upside of bogie upper plate 13, the tail end of described chute bottom plate 21 has inclined plane 22, bogie upper plate 13 has groove 14, and inclined plane 22 stretches to the inside of groove 14.
When chain needs reversion, scraper chain assembly enters transporter chute 20 along inclined-plane, sealing surface is formed between the tail end of chute bottom plate 21 and bogie upper plate 13, gap plugging is lived, scraper chain assembly can not touch the gap between bogie upper plate 13 and chute bottom plate 21 completely, therefore there will not be the phenomenon of chain jamming.
Further, the inclined plane 22 of chute bottom plate 21 tail end is several helical teeth, and the groove 14 on bogie upper plate 13 is the teeth groove matched with helical teeth.
In installation process, helical teeth is meshed with teeth groove, on the one hand improves assembly precision by location and installation, relative to the relative position of transporter chute 20, can improve the stability of equipment by bogie 10 in limiting scraper transporter work process on the other hand.
Further, the transition face between the plane of chute bottom plate 21 and inclined plane 22 is circular arc.Prevent scraper plate from occurring clamping stagnation through inclined-plane.
Preferably, the angle of inclination on inclined plane 22 is 15 ° to 30 °.
The angle on inclined plane 22 designs according to the concrete dimensional requirement of scratch board conveyor, has both been convenient to scraper plate and has slipped over inclined-plane and enter transporter chute 20, saved material simultaneously.
The utility model closes the sealing surface in gap by the cooperation composition between the inclined-plane of chute bottom plate and the groove of bogie upper plate, prevent scraper chain assembly to be stuck in gap, affect operating efficiency, and structure is simple, is convenient to install.
