Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a tracking and mapping device for underground pipelines with small diameters. Background Art

[0002] Pipeline detection at the trenchless underground pipeline construction site is carried out before the trenchless construction. Its main task is to find out whether there are any laid underground pipelines at the construction site (including water supply and drainage, gas, heat, industrial and other pipelines as well as power and telecommunication cables). If so, the plane position, direction, buried depth (or elevation), specifications, properties, materials, etc. of the underground pipelines are found, and an underground pipeline map is compiled.

[0003] The cam is provided with a plurality of camshafts, the cam being ...

[0004] When the above device is implemented, the lime powder in the storage barrel accumulates in one piece and falls very slowly. At the same time, the lime powder absorbs moisture in the air and condenses into clumps. The clumps of lime will block the connecting pipe after entering the connecting pipe, resulting in the lime powder being unable to fall to the ground mark, thereby affecting surveying and mapping. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a small-diameter underground pipeline tracking and mapping device to solve the technical problems in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a small-diameter underground pipeline tracking and mapping device, comprising a base, a material bin is connected to the middle of the top of the base through a bracket, a motor is provided on the back of the material bin, a crankshaft is connected to the output end of the motor, a rotating wheel and a traction rod are connected to the outside of the crankshaft, a breaking rod is connected to the outer surface of the rotating wheel, a screen is connected to the bottom of the traction rod, a plug rod is connected to the bottom of the screen, and a discharge pipe is connected to the bottom of the material bin.

[0007] Furthermore, a handrail is provided on one side of the top of the base, and the bottom of the base is connected to universal wheels via a damping rod, and the number of universal wheels is four.

[0008] By adopting the above technical solution, the device is pushed by the handrail, and the pipeline is marked on the ground along the path driven by the universal wheel. The device is shock-absorbing by the damping rod to prevent the receiver in the device from being damaged by shaking and affecting the surveying and mapping.

[0009] Furthermore, a clamping seat is provided on the other side of the top of the base, a receiver is provided in the middle of the clamping seat, a screw rod is provided at the bottom of the clamping seat, a threaded block is connected to the outside of the screw rod, a soft pad is connected to one side of the threaded block, and rocking wheels are provided at both ends of the screw rod.

[0010] By adopting the above technical solution, when marking the pipeline, the receiver is placed in the groove of the clamping seat, and the screw rod is rotated by shaking the hand wheel. Driven by the screw rod, the threaded block drives the soft pad to move in opposite directions to fix the receiver, thereby preventing the receiver from falling due to shaking. At the same time, the soft pad can prevent the receiver from being scratched by the clamping seat.

[0011] Furthermore, the soft pad abuts against the receiver, and the soft pad is made of rubber.

[0012] By adopting the above technical solution, rubber has the advantages of good elasticity and small deformation. The receiver is buffered by the rubber pad to avoid damage to the receiver during the clamping process of the receiver, thereby affecting the surveying and mapping.

[0013] Furthermore, the lower part of the material bin is tilted, and the discharge pipe is funnel-shaped.

[0014] By adopting the above technical solution, when marking, the staff turns on the motor, and the output end of the motor drives the crankshaft to rotate. Driven by the crankshaft, the traction rod drives the screen to move up and down, isolating large pieces of lime to prevent large pieces of lime from clogging the discharge pipe. The inclined setting makes it convenient for the lime powder to quickly fall into the discharge pipe, and the lime powder is discharged through the discharge pipe to be marked on the ground.

[0015] Furthermore, the plug rod fits in the lower part of the discharge pipe, and the plug rod is slidably connected to the discharge pipe.

[0016] By adopting the above technical solution, under the drive of the crankshaft, the screen drives the plug rod to move up and down repeatedly, so that the bottom of the plug rod is repeatedly inserted under the discharge pipe, the plug rod fits with the inner wall of the discharge pipe, and the discharge pipe is closed and opened, so that the discharge pipe intermittently sprinkles lime powder, thereby reducing losses.

[0017] Furthermore, there are two rotating wheels, and the two rotating wheels are symmetrically distributed.

[0018] By adopting the above technical solution, under the drive of the crankshaft, the two wheels drive the breaking rod to rotate, stir the lime powder above the screen, accelerate the falling speed of the lime powder, and at the same time break up the condensed lime so that it can pass through the holes on the screen, thereby improving the utilization rate of the lime.

[0019] Furthermore, there are a plurality of breaking up rods, and the breaking up rods are distributed in a circular array.

[0020] By adopting the above technical solution, driven by the rotating wheel, the breaking rod stirs the lime powder to avoid accumulation affecting the falling of lime, and at the same time breaks up the lime mass to improve the utilization rate of lime.

[0021] Furthermore, a notch is provided in the middle of the base, and the notch corresponds to the position of the discharge port of the discharge pipe.

[0022] By adopting the above technical solution, the lime powder in the discharge pipe slides out from the discharge port and falls to the ground through the notch for marking, thereby preventing the lime powder from falling onto the base, reducing the frequency of cleaning the base, and thus reducing the workload of the staff.

[0023] Furthermore, a rotating rod is connected to the top of the base, a supporting pad is connected to the bottom of the rotating rod, and a grip wheel is provided on the top of the rotating rod.

[0024] By adopting the above technical solution, when a break is needed during the journey, the staff can turn the grip wheel to move the rotating rod downward, drive the support pad to contact the ground, and then fix the device to prevent the device from slipping, especially when it is parked on a ramp.

[0025] In summary, the utility model mainly has the following beneficial effects:

The output end of the motor drives the crankshaft to rotate, and the traction rod drives the screen to move up and down, so as to shake the lime in the material bin, accelerate the falling speed of the lime, and screen out the condensed lime. At the same time, driven by the screen, the bottom of the plug rod is repeatedly inserted into the bottom of the discharge pipe, and the plug rod fits with the inner wall of the discharge pipe to close and open the discharge port of the discharge pipe, so that the discharge pipe intermittently sprinkles the lime powder, thereby reducing the loss;
