Description
Technical field
The utility model relates to a kind of controlling device, particularly relates to a kind of down-the-hole drill rear wheel controlling device.
Background technique
Existing down-the-hole drill rear wheel is in traveling process, and easily generation tread shoe and rear wheel deviate from phenomenon, affect job schedule, extend engineering time, also have potential safety hazard.As moved in drill-through journey, rear wheel is easily derailing, and easily causes and injures by a crashing object, be badly in need of improving rear wheel to operator or other objects.
Model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of down-the-hole drill rear wheel controlling device, and its structure is simple, safe and convenient, and cost is low, improves working efficiency and safety coefficient.
The utility model solves the technological scheme that its technical problem adopts:
Described down-the-hole drill rear wheel controlling device, comprise regulating block, bolt and catch, the central, transverse axis two ends of described down-the-hole drill rear wheel are connected with regulating block respectively, regulating block bottom symmetrical is provided with catch, be provided with polyurethane buffering layer inside catch, the center vertical pivot between two pieces of catch is provided with bolt.
Described catch is iron plate catch, and thickness is 8-12mm.
The quantity of described bolt is 4-8.
Moving in drill-through journey; start rear wheel; the regulating block thereupon driving rear wheel central, transverse axis two ends to connect is advanced along track together; in traveling process; bolt in described down-the-hole drill rear wheel controlling device and catch all play the effect of location; the polyurethane buffering layer be provided with inside catch, can play a protective role to catch when rear wheel generation slight shift, anti-stop tab is damaged.
The beneficial effect that the utility model has is:
The utility model structure is simple, safe and convenient, and cost is low, effectively prevents tread shoe and rear wheel from deviating from the generation of phenomenon, improves working efficiency and safety coefficient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1, regulating block; 2, rear wheel; 3, catch; 4, bolt; 5, polyurethane buffering layer.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Embodiment 1
As shown in Figure 1, described down-the-hole drill rear wheel controlling device, comprise regulating block 1, bolt 4 and catch 3, the central, transverse axis two ends of described down-the-hole drill rear wheel 2 are connected with regulating block 1 respectively, regulating block 1 bottom symmetrical is provided with catch 3, the center vertical pivot be provided with inside catch 3 between polyurethane buffering layer 5, two pieces of catch 3 is provided with bolt 4.
Described catch 3 is iron plate catch 3, and thickness is 10mm.
The quantity of described bolt 4 is 8.
Moving in drill-through journey; start rear wheel 2; the regulating block 1 thereupon driving rear wheel 2 central, transverse axis two ends to connect is advanced along track together; in traveling process; bolt 4 in described down-the-hole drill rear wheel 2 controlling device and catch 3 all play the effect of location; the polyurethane buffering layer 5 be provided with inside catch 3, can play a protective role to catch 3 when slight shift occurs rear wheel 2, and anti-stop tab 3 is damaged.
The utility model structure is simple, safe and convenient, and cost is low, effectively prevents tread shoe and rear wheel 2 from deviating from the generation of phenomenon, improves working efficiency and safety coefficient.
