Abstract

The utility model relates to an ice surface boring device which used in the hydrological test to bore a hole of a certain size on a frozen ice cover to let through a current meter or a peripheral apparatus down into the water flow under the ice to do test. The device comprises four members: an ice cutting member, a bracket, a power member and a transmission member. A horizontal shaft is arranged on a bracket steel plate with bearing at the front part of the bracket. Several disk saws are mounted on the rotary shaft to construct an ice cutting wheel. A gasoline engine is adopted as the power supply to drive the ice cutting wheel to rotate to cut the ice to break the contacted ice to form an ice hole. When working, the ice cutting wheel can be freely move and the advancing direction of the ice cutting wheel can be freely changed, so as to deepen and enlarge the ice hole to realize the goal of putting down the apparatus and the equipment. The utility model can adopt a toothed disk saw with alloy bit to bore holes or to dig on the surface of something which is made of the reinforce concrete, the brick and the soil, etc.

Description

The portable ice maker of beating of hydrologic survey saw pick

Affiliated technical field

The utility model relates to a kind of ice face perforating device.

Background technology

The subglacial water velocity is generally test with current meter at present behind the ice age river freezeup, need transfer to current meter and relevant device in the flowing water when testing the speed, this just need open freeze-up ice face an ice hole of certain size, and current meter is transferred in the subglacial flowing water by the ice hole.Will satisfy current meter and relevant device exactly to the requirement of ice hole size can transfer in the flowing water.The 25-1 type current meters that use during measurement more, the long 0.53m of instrument type, molded breadth 0.12m, the minimum in other words square ice hole that will get long 53cm, wide 12cm.If use fish lead during test, then ice the requirement of transferring that hole dimension also needs to satisfy fish lead.

At present, the known ice hole instrument of beating has hand-held fluted drill, pickax, spade, drill rod etc., and beating ice hole equipment has ice auger, ice saw etc.Use hand-held fluted drill only can bore a small sircle hole, current meter and relevant not getting ready can't be put in the flowing water.Get the slotted hole that to put into current meter and relevant device, need to cooperate with instruments such as pickax, spade, drill rods, its distinct issues are exactly to lean on manpower operation, inefficiency fully, intensity is big, and increasing work efficiency and changing condition of work is hydrologic survey personnel strong desires for many years.Though wide-aperture ice auger is arranged at present, but aperture 20cm, need 3 borings arranged side by side just can meet the demands, and because no security protection, under high rotating speed (per minute be'ss thousands of to nearly ten thousand commentaries on classics) situation, may damage the person at any time, under the prerequisite of " safety first ", " people-oriented ", " safe veto by one vote ", it is difficult applying.The work that reflects 3 borings arranged side by side according to the field operation comrade is also very difficult: when distance is near, slide to first hole easily during second hole operation; During distance, there is thicker interlayer between two holes, eliminates difficulty of interlayer.There is the disk of use sawing ice in northeast at present, if cut the thick ice of 1m, needs the above saw blade of diameter 2m, and this also is difficult to realize in actual applications.Also useful chain saw saw ice, existing chain saw guide plate length generally is no more than 0.5m, can't satisfy the ice thickness requirement, saw in the plane ice saw thoroughly ice equal white saw, if the lengthening guide plate then can bring problems such as safety, structural performance, can operate as normal still not know.Do not have to solve hydrologic survey and beat effective equipment that ice hole problem can guarantee work safety again.

Summary of the invention

In order to solve the ice hole problem of beating of freeze-up ice face of hydrologic survey ice age, the utility model provides a kind of saw pick that utilizes combined saw blade under machine power drives ice body to be pulverized the portable ice hole equipment of beating.

The technical problems to be solved in the utility model:

1. the material of selector disc saw blade, type, size, quantity; 2. select suitable saw blade syntagmatic, the reasonable clearance between each saw blade; 3. select effective power transmission mode and light equipment supporter reasonable in design; 4. select suitable power-equipment; 5. solve safety protection structure.

Technical scheme

The technical scheme that its technical problem that solves the utility model adopts is: a plurality of circular saw bits compositions are installed on the turning cylinder of a horizontal stroke are cut the moon, utilize the rotation of cutting the moon that ice body is cut, make the pulverizing of freezing of contact position, form the ice hole.Can arbitrarily move the cutting direction that the moon is cut in the moon or change of cutting of rotating, the ice hole is enlarged, reach the purpose that current meter and relevant device are transferred in hydrologic survey.The utility model structure is divided into cuts ice, support, power, transmission four parts: 1. cut to ice partly to be made up of coaxial saw blade and cut the moon.2. support holds steel plate by three-dimensional welding steel, steel pipe pole, intermediate transfer bearing shaft and tape spool and forms.3. gasoline engine is adopted in power section, and gasoline engine weight is lighter, generally below 10kg.4. running part uses one-level or secondary transmission with belt or chain.The thin pole of ice sheet is used the one-level transmission more in short-term, and belt is directly connected to the preceding belt pulley of cutting on the moon by power wheel.When the thicker need of ice sheet pole is longer, use the two-stage transmission, one-level passes to breast wheel by power wheel, and one-level is passed to by breast wheel and cuts the moon.Cutting the moon is the part that directly acts on ice body, and the high speed rotation can bring beyond thought situation.Considered during design that saw blade fragmentation and belt break to operating personnel's threat, so be added with protective cover behind the saw blade, belt transmission partly is added with protective cover.

The beneficial effects of the utility model are: 1. utilize saw blades groups to form and cut the moon, can effectively cut ice body, form the ice hole of arbitrary shape, satisfy need of work.2. use gasoline engine to be used as power, make equipment light, operate easily and carry, reduce operating personnel's physical demands, reduce labor intensity.3. use mechanical work, overcome the manpower operation with the activity duration prolong physically-draining situation, keep operating speed, increase work efficiency; 4. solve the unsafe problems in producing.
