A kind of hoisting frame of heavy type cone penetrometer
The utility model relates to the technical fields of engineering detecting equipment, more particularly, to a kind of promotion of heavy cone penetrometer
Heavy type cone penetrometer is at present mainly for detection of foundation bearing capacity, mainly by manually lifting heavy cone penetrometer away from ground
Behind 2 meters of face, loosing one's grip makes its heavy cone penetrometer movement of falling object make engineering geology to foundation soil using its jolt capacity
Prior art among the above have the following deficiencies: the general weight of heavy cone penetrometer at 150 jin or so,
And since 2 meters of ground need to be raised to, therefore four struts are uniformly circumferentially fixed with along it on the peripheral wall of heavy cone penetrometer, generally required
Four adults hold with a firm grip a strut respectively, could lift heavy cone penetrometer, complete its detection to ground, such usage mode
To the labor intensity of staff is greatly improved, it is unfavorable for continuing working for staff, leads to its work to foundation detection
Utility model content
The purpose of the utility model is to provide a kind of hoisting frames of heavy cone penetrometer, and heavy feeler inspection can easily be promoted by having
Instrument reduces intensity of workers, improves the effect of staff's working efficiency.
The above-mentioned purpose of utility model of the utility model has the technical scheme that
A kind of hoisting frame of heavy type cone penetrometer, including rack, rack is including four support rods and is fixed on four supports
The top frame of bar upper end is respectively arranged with mounting base on four side walls of the top frame, and each mounting base is rotatably connected to by shaft
One rotating wheel, the rotating wheel are coaxially fixed with shaft, and drawstring, the other end of the drawstring are respectively fixed on each rotating wheel
It further include the actuator of drive shaft rotation for being connect with the strut of heavy cone penetrometer outer wall.
By using above-mentioned technical proposal, drives each rotating wheel to rotate by actuator, it is made to carry out coiling to drawstring,
To which with drawstring, gradually coiling plays castering action to heavy cone penetrometer on rotating wheel, until heavy cone penetrometer is promoted to
When wanted height, the driving force to rotating wheel is released, makes its heavy cone penetrometer under Gravitative Loads, the movement of falling object utilizes
To the effect of impact of ground, Engineering Geology Evaluation is made to foundation soil；Utilize the supporting role of rack and turning for rotating wheel
Movement is used, and can greatly be reduced the labor intensity of staff, be improved the working efficiency of staff.
The utility model is further arranged to: the actuator includes four drivings being coaxially fixed in shaft respectively

To drive the rotation work of shaft and rotating wheel.
The utility model is further arranged to: by gear drive between the adjacent rotating wheel, realization synchronizes anti-
To rotation；The actuator includes with the co-axially fixed driving wheel of one shaft and coiling on driving wheel and for the people that works
The transmission belt that member pulls.
By using above-mentioned technical proposal, realizes that the synchronous backward of all rotating wheels works by gear interlinked mechanism, make
It only needs a staff to pull transmission belt, under the matching relationship of transmission belt and driving wheel, one rotating wheel is driven to rotate
While, all rotating wheels can be driven to rotate simultaneously towards the side outside rack or towards the side in rack, heavy cone penetrometer is risen
To castering action, the effect for saving human resources can reach.
The utility model is further arranged to: the gear drive includes the cone for being coaxially fixed on both ends of the shaft respectively
Gear, the bevel gear intermeshing between adjacent shafts.
It achieves and is mutually perpendicular to by the bevel gear mating reaction between adjacent shafts by using above-mentioned technical proposal
While the synchronous rotation of shaft, using the acting in opposition of adjacent bevel gear, rotating backward for adjacent shafts is realized, to realize
Four rotating wheels are rotated towards the side outside rack or towards the side in rack simultaneously.
The utility model is further arranged to: the driving wheel is set as gear, and the transmission belt is set as nibbling with gear
The rack gear band of conjunction.
Guarantee rack gear using the meshing relation of wheel and rack interband double wedge and tooth socket by using above-mentioned technical proposal
Transmission efficiency of the band to double wedge.
The utility model is further arranged to: mounting rod is provided between adjacent supports bar, the transmission belt is sheathed on installation
Outside bar and top frame.
By using above-mentioned technical proposal, transmission belt coiling is in outside mounting rod, top frame, making its heavy cone penetrometer freely falling body
When movement drives driving wheel quick rotation, transmission belt will not be fallen from rack.
The utility model is further arranged to: the mounting rod is fixed with the lantern ring passed through for transmission belt, on the lantern ring
It is threaded with abutting bolt, in the abutting bolt rotation process, side abuts with transmission belt and pushes against transmission belt in peace
It fills on bar.
By using above-mentioned technical proposal, it is threadedly engaged active force by push against bolt and lantern ring, makes it by transmission belt
It pushes against when on mounting rod, the height of heavy cone penetrometer can be limited；Adjust it can according to actually detected demand over the ground
The frequency that base is hit.
In conclusion the advantageous effects of the utility model are as follows:
1. driving driving wheel that shaft is driven to rotate using transmission belt, and then rotating wheel is driven to drive drawstring coiling, to heavy type
Cone penetrometer plays castering action, it is made to can reach reduction intensity of workers, improves the effect of staff's working efficiency；
2. be intermeshed by the bevel gear of the fixed bevel gear of both ends of the shaft and adjacent rotated, realize adjacent shafts with
And the synchronous backward rotation of rotating wheel, make it only and need driving one shaft rotation, can be realized four rotating wheels to drawstring around
Work is rolled up, achievees the effect that save human resources.
