Description
Technical field
The present invention relates to construction equipment in the pipeline, especially a kind of from the interior equipment of the pipeline of walking.
Background technique
Construction equipment such as internal clamp, internal welding machine etc. the equipment of certainly walking in the pipeline, can not when surpassing 30 °, the gradient walk, when the upward trend walking, because the parking poor reliability that the control mode of brake control valve and the interlocking of walking control valve causes, in addition, the slope easily occurs to slip during descending, and very large potential safety hazard is arranged.
Summary of the invention
In order to overcome can not being applicable to the larger occasion of the gradient, poor reliability, having the deficiency of potential safety hazard of construction equipment in the existing pipeline, the invention provides and a kind ofly be applicable to effectively that the larger occasion of the gradient, reliability are good, the upward slope safety guarantee car of equipment in the pipeline of certainly walking that eliminates safe hidden trouble.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of upward slope safety guarantee car of in the pipeline of walking, equipping, comprise vehicle frame, driving wheel and pawl, arrange 3 driving wheels and 3 pawls on the described vehicle frame, radially direct is that 3 driving wheels and 3 pawls are all symmetrical about Y-axis, driving wheel is installed in an end of driving wheel support arm by a bearing pin, the middle part of described driving wheel support arm is installed in rotation on the first turning axle, described the first turning axle is fixedly mounted on the vehicle frame, the other end of described driving wheel support arm connects with sliding sleeve by hinge, and described driving wheel is connected with drive unit; Described pawl is installed in connecting rod one end, the middle part of described connecting rod is installed in rotation on the second turning axle, described the second turning axle is fixedly mounted on the vehicle frame, and the other end of described connecting rod is installed on the vehicle frame, mounting spring on the connecting rod between described the second turning axle and the vehicle frame;
Described sliding sleeve slidably is sleeved on the hollow shaft, and described hollow shaft is fixedly mounted on the vehicle frame, and described electric pushrod is positioned at hollow shaft, and the moved end of described electric pushrod and the interlock of described sliding sleeve.
Further, look up from axle, the angle of driving wheel and pawl is 60 °.
Further, described drive unit comprises stepper motor and synchronous belt drive mechanism, described stepper motor is installed on the driving wheel support arm, the active synchronization wheel is installed on the output shaft of described stepper motor, described active synchronization wheel is connected described passive and synchronous the wheel on the wheel shaft that is installed in described driving wheel with passive and synchronous the wheel by Timing Belt.
On the described vehicle frame approach switch is installed, described approach switch cooperates with trigger end on the connecting rod.
Winch is installed in the described vehicle frame, and described winch is provided with cable wire, and described cigarette machine is connected with actuating motor.
Beneficial effect of the present invention is mainly manifested in: this upward slope safety guarantee car has adopted novel walking drive mechanism, and the ability of certainly walking is strong.By with the pipeline of certainly walking in equip and be used in combination, certain anti-slip slope protection is provided when being equipped in larger upgrade walking in the pipeline of certainly walking.
Description of drawings
Fig. 1 is the structural drawing of the upward slope safety guarantee car of equipment in the pipeline of walking.
Fig. 2 is the side view of Fig. 1.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
See figures.1.and.2, a kind of upward slope safety guarantee car has cylinder cage type vehicle frame 1, and there is hollow shaft 2 at the vehicle frame center, and there is slidable sliding sleeve 3 its outside, and driving mechanism is arranged symmetrically with around hollow shaft.This car is by battery 4 power supplies, and controller 5 is controlled.The winch 15 that actuating motor 16 drives is installed in the car.
If when being fixed on electric pushrod 8 retraction on the central shaft, promote sliding sleeve 2 the wheel support arm is rotated, driving wheel is along with the motion of wheel support arm is pressed on the tube wall.When stepper motor 13 rotates, drive by synchronous belt mechanism 14, thereby traction vehicle frame 1 is walked at pipeline internal.When electric pushrod 8 stretches out, sliding sleeve 2 is along with the pulling wheel support arm of returning of electric pushrod 8 makes driving wheel break away from tube wall.
Upward slope safety guarantee car and other pipeline are interior from walking the engineering truck work in combination.When uphill gradient is larger, to walk safely for ensureing whole engineering truck, upward slope safety guarantee car is walked first.When upward slope safety guarantee garage goes to the pipeline end, connecting rod 11 stretches out pawl 10 outside the pipeline under the effect of spring force and keeps off on the ducting side edge, approach switch on the connecting rod 11 17 output control signals make upward slope safety guarantee car stop walking simultaneously, and simultaneously, winch 15 also stops to put wirerope.Along with electric pushrod 8 stretches out, the block on the sliding sleeve 2 is leant on connecting rod 11 gears, so that three pawls 10 can not retracted under external force.After the safe wirerope tension, the more upwards walking of engineering truck of certainly walking, winch 16 is received wirerope simultaneously.Because the fast self-locking device of similar automobile safety belt is arranged on the winch, when occurring from the engineering truck of walking during to the trend that glides, the wirerope on the upward slope safety guarantee car can be held it, thereby ensures that whole engineering truck can not be slipped to the pipeline depths.
