Description
Technical field
The utility model relates to cutting equipment technical field, and particularly a kind of Rock cutting is sawed.
Background technology
In civil engineering projects, often need the cutting that professional cutting equipment has come large-scale structures or rock, thus rid prevent the objects such as cave-in accident.Hydraulic saw because of its to building or rock, the earthwork to cut off broken face more neat and apply comparatively extensive.Chinese patent (Authorization Notice No. is CN202344029U) discloses one " hydraulic disc cast-cutting saw ", its structure comprises hydraulic hose, handle control valve assembly, thrust plate, handle, motor bracket, hydraulic motor, saw blade cover, cooling water pipe, saw blade, wherein, the handle of handle control valve assembly is provided with trigger and Safety buckle, the hydraulic fluid port of handle control valve assembly lower end is connected with hydraulic hose, and front end is connected with thrust plate; Hydraulic motor is arranged on motor bracket by bolt; Saw blade cover is bolted on motor bracket, and the saw blade be placed in saw blade cover is connected on the output shaft of hydraulic motor by platen; Cooling water pipe to be welded in inside saw blade cover and corresponding with platen position; Handle front end connecting motor support, rear end connects thrust plate.Its operation principle is: during work, the corresponding hydraulic fluid port of handle control valve assembly is connected with the oil pipe of hydraulic power station, hydraulic oil enters handle control valve assembly, now press trigger and Safety buckle, fluid is entered in hydraulic motor through hydraulic hose, and forms hydraulic circuit, driving hydraulic motor rotates, driving saw blade to carry out circumgyration incision simultaneously, when cutting, through cooling water pipe, saw blade being cooled from the water in pressure water tank.But, the defect of above-mentioned " hydraulic disc cast-cutting saw " is: although the effect arranging Safety buckle is in order to avoid staff occurs maloperation in use, but because Safety buckle and trigger are all arranged on handle, make the close together of Safety buckle and trigger, thus, operator people is when hand-held handle, still there is a strong possibility occurs that phenomenon is touched in false touch, make the serious forgiveness of above-mentioned cast-cutting saw lower, and then cause safety coefficient when using lower, be difficult to the personal safety of abundant safeguard work personnel.Therefore be necessary to improve prior art.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provide a kind of simple and reasonable, easy to operate, safety coefficient is higher, fully can ensure that the Rock cutting of user's personal safety is sawed.
For achieving the above object, the utility model is by the following technical solutions:
Rock cutting saw described in the utility model, comprise link, saw blade, in-line, return line and handle, described handle is fixedly mounted on described link, one end of described link is installed and is provided with handle control valve assembly, the other end of described link is provided with hydraulic pump, described handle control valve assembly is provided with gauge tap, described handle control valve assembly is connected with described hydraulic pump by described return line, described saw blade is connected on the output shaft of described hydraulic pump by platen, described handle control valve assembly is connected with the cooling water pipe with described platen corresponding matching, described link is also provided with manual switch valve, the input of described manual switch valve is connected by pipeline with described handle control valve assembly, the output of described manual switch valve is connected with described hydraulic pump by described in-line.
Further, described manual switch valve is set to ball valve.
Further, described gauge tap comprises trigger on the handle being arranged on described handle control valve assembly and Safety buckle.
The beneficial effects of the utility model are: compared with prior art, the utility model by arranging manual switch valve on link, the input of manual switch valve is connected by pipeline with handle control valve assembly, the output of manual switch valve is connected with hydraulic pump by in-line, during work, first staff pulls manual switch valve, and then presses the gauge tap on handle control valve assembly, thus make oil circuit form conducting state, and then make hydraulic pump works and drive saw blade to rotate.When not pulling manual switch valve, even if now staff presses the gauge tap on handle control valve assembly because of maloperation, hydraulic pump also can not drive saw blade to rotate, and, because manual switch valve is arranged on link, make the distance between manual switch valve and gauge tap relatively far away, thus substantially increase serious forgiveness, the effective guarantee personal safety of user, and then effectively improve safety coefficient of the present utility model.The utility model vibrational power flow advantages of simple.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In Fig. 1:
1, link; 2, saw blade; 3, in-line; 4, return line; 5, handle; 6, handle control valve assembly; 61, trigger; 62, Safety buckle; 7, hydraulic pump; 8, platen; 9, cooling water pipe; 10, manual switch valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Rock cutting saw as shown in Figure 1, comprise link 1, saw blade 2, in-line 3, return line 4 and handle 5, handle 5 is fixedly mounted on link 1, one end of link 1 is installed and is provided with handle control valve assembly 6, handle control valve assembly 6 is provided with gauge tap, specifically, gauge tap comprises trigger 61 on the handle being arranged on handle control valve assembly 6 and Safety buckle 62, the other end of link 1 is provided with hydraulic pump 7, handle control valve assembly 6 is connected with hydraulic pump 7 by return line 4, saw blade 2 is connected on the output shaft of hydraulic pump 7 by platen 8, handle control valve assembly 6 is connected with the cooling water pipe 9 with platen 8 corresponding matching, link 1 is also provided with manual switch valve 10, the input of manual switch valve 10 is connected by pipeline with handle control valve assembly 6, the output of manual switch valve 10 is connected with hydraulic pump 7 by in-line 3.
During work, first staff pulls manual switch valve 10, and then presses the gauge tap on handle control valve assembly 6, thus makes oil circuit form conducting state, and then hydraulic pump 7 is worked and drives saw blade 2 to rotate.When not pulling manual switch valve 10, even if now staff presses the gauge tap on handle control valve assembly 6 because of maloperation, hydraulic pump 7 also can not drive saw blade 2 to rotate, and, because manual switch valve 10 is arranged on link 1, make the distance between manual switch valve 10 and gauge tap relatively far away, thus substantially increase serious forgiveness, the effective guarantee personal safety of user, and then effectively improve safety coefficient of the present utility model.The utility model vibrational power flow advantages of simple.
As a kind of preferred embodiment, in order to make, the utility model vibrational power flow is simpler, manufacturing cost is lower, more convenient operation, and manual switch valve 10 is set to ball valve.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
