Description

Cable trench inspection trolley and track for transformer substation

Technical Field

The utility model relates to a transformer substation operation maintenance technical field, concretely relates to transformer substation's cable pit inspection dolly and track.

Background

The cable trench is an indispensable infrastructure of a transformer substation, cables in the trench not only relate to power transmission, but also relate to equipment such as relay protection, automatic control, communication, measurement and metering, and are a neural center of the transformer substation, once the cables break down, the difficulty of checking and processing is large, the time is long, relay protection or a control loop can be out of work, accidents are expanded, even a main device is damaged, and production cannot be recovered for a long time.

In order to guarantee the safe and stable operation of the cable trench, the cable trench needs to be regularly patrolled, including the fireproof plugging of the inspection cable trench, whether have the toy, whether soak, whether the cable damages etc. The inspection quality of the cable trench is directly related to the safe and stable operation of the cable trench. Because the cable trench cover plate of the transformer substation is made of cement, the weight is large, and personnel can check the cable trench cover plate only by opening the cover plate during patrol; meanwhile, the cable trench has narrow and short environment, and people are very inconvenient to go in and out and move after entering the cable trench, so that the quality and the efficiency of inspection work are seriously influenced.

Therefore, in order to solve the above problems, a cable trench patrol trolley and a cable track for a transformer substation are needed, which can replace the inconvenience of personnel entering and exiting the cable trench to patrol, reduce the workload of the workers, improve the patrol efficiency and avoid the existence of patrol dead angles.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at overcoming the defect among the prior art, providing transformer substation's cable pit inspection dolly and track, can replace personnel's business turn over to detect the inconvenience of inspecting cable pit and solving personnel's business turn over and go out the cable pit inspection, reduce staff's work load, improve inspection efficiency, avoid the existence at inspection dead angle.

The utility model discloses a dolly and track are tourd to cable pit of transformer substation, include the dolly body and set up the wireless camera on the dolly body, the wheel of dolly body all has limit baffle's spacing wheel and front wheel for both ends face and can set up on the dolly body in order to follow axial displacement's mode, and the wireless camera is from taking wifi's wireless camera, links to each other with intelligent terminal through app, and the image that will shoot returns intelligent terminal, and operating personnel only need can patrol all the circumstances of each angle in the cable pit through the image observation.

Furthermore, the surface of the wheel is covered with a layer of anti-slip rubber skin for preventing the wheel from sliding during running and ensuring the stability of the trolley body in the running process.

Further, limit baffle is circular and the diameter is greater than the wheel diameter, and circular limit baffle can avoid producing the rotation of wheel and interfere and guarantee better spacing following the wheel pivoted in-process.

Furthermore, the front wheel is sleeved on a front axle of the trolley body and can relatively slide on the corresponding half axle, the front wheel is used for steering, the smooth steering can be better ensured for the wheels which can slide on the axle, and the wheels are prevented from being stuck at the turning positions of the tracks.

Furthermore, the wireless camera is arranged on the base of the trolley body through a universal telescopic rod, the universal telescopic rod is connected with the base through an NBC joint, the NBC joint is mainly used for connecting the camera, and the telescopic rod can be guaranteed to be electrically connected with power supply equipment and the like arranged on the base when rotating.

Further, be provided with universal telescopic link on the dolly body and accomodate the groove and be used for accomodating the universal telescopic link that is in the contraction state, when the dolly is in out-of-operation state, can accomodate universal telescopic link and place in accomodating the groove, portable and management.

Further, the driving wheel of the trolley body is a rear wheel, the rear wheel is driven by the motor, and the rear wheel serves as the driving wheel due to the fact that the axial degree of freedom between the rear wheel and the rear axle is limited, and driving stability of the driving wheel is better.

The utility model provides a track, includes that two set up the current rectangle side's pipe of confession dolly body side by side, by many pillow strip fixed connection between the two rectangle side's pipe, form relatively fixed track and supply the dolly current.

Furthermore, the pipe wall width that rectangle side's pipe is used for supporting the wheel is less than the wheel width, guarantees that the limit baffle who connects in wheel both ends face is located rectangle side's pipe both sides, with the wheel spacing on the track guarantee the stability of traveling and pass through.

The utility model has the advantages that: the utility model discloses a transformer substation's cable pit tours dolly and track, through predetermineeing the track in the cable pit, the dolly takes wireless camera to pass along predetermineeing the track, and wireless camera can follow advancing of dolly and carry out the tour at no dead angle to the cable pit, has replaced artifical business turn over to detect the inconvenience that patrols cable pit solver and advance out the cable pit and patrol, reduces staff's work load, improves and patrols efficiency.

Drawings

The invention will be further described with reference to the following figures and examples:

FIG. 1 is a schematic view of the structure of the cart of the present invention;

fig. 2 is a schematic structural view of the wheel of the present invention;
