Abstract
The invention relates to an automotive self-rescue traction machine and discloses a safe traction machine. The safe traction machine comprises a supporting column, a fixing column and a traction rope; the supporting column comprises a supporting rod and an inclined rod; a rolling wheel is arranged on the inclined rod; a fixing base is arranged under the supporting rod; the fixing column comprises an external fixing shaft sleeve and an internal spiral fixing column; the external fixing shaft sleeve enables the internal spiral fixing column to be further fixed during the lifting process due to automobile pulling, the fixation firmness of the integral fixing column is strong, and the fixing column can bear large tensile force. Compared with the prior art, the safe traction machine has the advantages of enabling an automobile trapped in sludge to get out of the sludge due to self-power of the automobile and solving the problem that the automobile requires external force or a small car with light weight to drag to get out of the sludge when being trapped in the sludge.
Description
Technical field
The invention belongs to a kind of automobile tractor, be specifically related to a kind of automobile self-rescuing tractor.
Background technology
In the time that automobile sails heavy road face or roadbed into and is absorbed in pit compared with soft road surface, wheel there will be the phenomenon of skidding, and now, although the drive wheel of automobile ceaselessly rotates, automobile can not be moved, and can only rely on trailer or crane just can get out under.If but when automobile is got down hopeless in a quagmire in more remote area, trailer and crane often can not come to rescue timely, therefore, also has now a kind of tractizer, use the electric power in automobile storage battery to roll pit away from windlass automobile, but this tractizer has three shortcomings, and the larger tractizer of first tractive force is heavier, heavier tractizer affects the off-road capability of automobile; It two is that high-power tractizer is very easy to exhaust the electric power in automobile storage battery while using for a long time; Finally, this tractizer easily damages the sensor of safety air bag when mounted, easily causes safety misadventure.Have again now a kind of automobile tractor, its principle of work is that tractor one end is fixed on hard ground for this reason, and the other end is fixed on the wheel hub of motor tire, and the power that then relies on car engine rear-wheel hub to rotate, pulls automobile to roll pit away from automatically.This tractor does not need extra power just can make automobile roll pit away from, but this tractor need to firmly be fixed on hard ground, otherwise easily tractor is extracted in the time of automobile starting, causes and draws unsuccessfully.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of safe tractor is provided, can rely on the power of automobile self allow to be trapped in the automobile in muddy get rid of poverty, solve automobile in the past and be trapped in the muddy problem that needs external force traction or can only allow the lighter compact car of weight rely on the power traction of self to get rid of poverty when middle.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of safe tractor, comprise pillar stiffener, fixed leg and hauling rope, described pillar stiffener comprises strut bar, described supporting bar top is provided with tilting bar, on described tilting bar, be provided with roller, described strut bar is arranged with permanent seat, described fixed leg comprises outer fixed hub and inside spin fixed leg, in described outer fixed hub, rotate and be provided with annular ring, described annular ring inwall is evenly provided with some vertical Jia Chi roads, described inside spin fixed leg comprises connector and conveyor screw, on described connector, be evenly provided with the Yi Chi road that matches with described Jia Chi road, on described conveyor screw, be provided with helical tooth road, on described connector, be provided with vertical slots, in described outer fixed hub, detouchable is provided with the cross bar matching with described vertical slots, described outer fixed hub bottom is provided with several fixing inserted links, described annular ring top is provided with annular tooth road, on described annular tooth road, be provided with first finishing bevel gear cuter, on described first finishing bevel gear cuter, be provided with rotating shaft, in described rotating shaft, be provided with crank, described hauling rope comprises connection cord, divide rope clamp and static line, on described connection cord, be provided with nave boss anchor fitting, the connection cord of described point of rope clamp described in connecting two, described static line connects described crank by described roller.Arrange like this, principle of the present invention is to utilize the rotation that is absorbed in muddy middle tire self, drives nave boss anchor fitting storage connection cord, then relies on the fixed leg fixing on the ground to pull automobile to roll away from voluntarily muddy.Outstanding feature of the present invention is the double-decker that fixed leg adopts outer fixed hub and inside spin fixed leg, after device sets, pulling force after automobile starting first acts on outer fixed hub, now outer fixed hub can drive inside spin fixed leg to continue to be rotated down in being pulled, because the constant intensity of the fixed sturcture of inside spin fixed leg is much larger than outer fixed hub, when cross bar blocks after vertical slots, outer fixed hub and inside spin fixed leg become a stressed entirety, the pulling force that fixed leg can bear is like this larger, make heavier automobile can rely on the power of self to roll muddy district away from.
In technique scheme, preferred, on described roller, be provided with protecting sleeve.Arrange like this, can prevent that static line from deviating from from roller.
In technique scheme, preferred, described nave boss anchor fitting comprises A-frame, in the middle of described A-frame, be provided with and harass and disturb bar, the described bar of harassing and disturbing is fixedly connected with described connection cord, and described harassing and disturbing on bar is provided with baffle plate, and described three end points of A-frame are provided with closed lock.Arrange like this, lock and nave boss anchor fitting can be fixed on nave boss by closure, when then nave boss rotates, harass and disturb bar and start to receive connection cord, allow automobile is pulled out by fixed leg.
In technique scheme, preferably, described permanent seat comprises reaction plate, is evenly provided with several movable bracing frames on described reaction plate, described bracing frame is provided with locating dowel pin with the part that described reaction plate is connected, and the described bracing frame other end is provided with fastening nail.Arrange like this, because the roller on pillar stiffener need to change the force direction that is subject to of hauling rope, so pillar stiffener also can be subject to the pulling force that automobile is larger, therefore several bracing frames are set, allow pillar stiffener also firmly fix on the ground.
In technique scheme, preferred, described connector top is provided with rotation-limited groove, on described rotation-limited groove, is provided with departing revolving bar.Arrange like this, can person easy to use inside spin fixed leg be screwed into subsurface.
In technique scheme, preferred, on described fixing inserted link, be provided with bulged tube.Arrange like this, on fixing inserted link, bulged tube is set and can allows outer fixed hub bear larger pulling force.
Compared with prior art, the invention has the beneficial effects as follows: can rely on the power of automobile self allow to be trapped in the automobile in muddy get rid of poverty, solve automobile in the past and be trapped in the muddy problem that needs external force traction or can only allow the lighter compact car of weight rely on the power traction of self to get rid of poverty when middle.
