Technical Field

The invention relates to the field of cable wells, in particular to edge gap impurity removing equipment for opening a cable well cover plate.

Background

At present, in urban distribution network engineering construction, the prefabricated cover plate of cable trench inspection well and inspection well is all made according to the typical design requirement of all kinds of standard specifications, because cable trench inspection well cover plate size and weight are all bigger in the distribution network typical design, consequently, when developing to patrol and examine the maintenance to the cable channel, the process of opening cable trench inspection well cover plate is comparatively troublesome. In the prior art, a crowbar is generally used in a method for opening a cable trench inspection well cover plate, a worker holds the crowbar to pry into a small hole in the inspection well cover plate and then prys open the well cover plate forcibly, a large amount of manpower is consumed in the process, and meanwhile, a protrusion or a recess is easily formed in the surface of the cover plate, so that the cover plate is damaged. The reason that the cable well cover plate is difficult to open is often that too much dust, mud and other impurities are carried in gaps at the edge of the cover plate and are washed into the gaps. Under the bonding of clay matter in earth, these debris form fine and close and stable structure, block in the gap at apron edge, and then have leaded to the apron to block seriously, are difficult to open fast.

Aiming at the problem that a cable well cover plate is difficult to open in the prior art, the invention provides edge gap impurity removing equipment for opening the cable well cover plate. The two inserting rods are respectively positioned at the bottoms of the two ends of the mounting rod, and the axis of each inserting rod is perpendicular to the long axis of the mounting rod, so that when the mounting rod is horizontal, the inserting rods are necessarily vertically downward. Because the cable well cover plate is provided with two lifting holes, the invention makes full use of the two existing lifting holes to ensure that the two insertion rods are respectively inserted into the two lifting holes, and because the distance between the two lifting holes on the well cover plate is fixed, the invention only needs to reasonably set the distance between the two insertion rods according to the different batch models of different well cover plates. Set up the pivot on the installation pole, the axis of pivot is crossed the mid point of installation pole along major axis direction, the pivot can rotate around self axis, and the connecting rod passes the pivot makes the axis of connecting rod intersect perpendicularly with the axis of pivot, and consequently the connecting rod can rotate along with the pivot, and the screw thread through-hole of intercommunication about the one end of connecting rod sets up, insert the screw rod in the screw thread through-hole, the cone of big-end-up is convenient for the disect insertion to the gap at apron edge through the pointed end of cone bottom to the bottom of the screw rod. The nut is established to the cover on the screw rod, the nut is located the top of connecting rod, consequently through the cooperation of screw thread through-hole with the screw rod for the cone height-adjustable makes even piled up in the gap by debris, also can insert the cone to the gap through the mode of rotatory screw rod. The other end of the connecting rod is fixed with an air pump, the output end of the air pump is connected with a metal conduit, the metal conduit is vertically downward, the axis of the metal conduit is parallel to the axis of the screw rod, air is blown into the metal conduit through the air pump, and an auxiliary cone cleans impurities in the gap. Set up a plurality of first jacks that distribute along the axis direction evenly on the connecting rod, set up two second jacks that distribute along the connecting rod axis direction in the pivot, second jack, first jack size equal, the distance between two second jacks equals the distance between two adjacent first jacks, still including running through simultaneously the bolt of second jack, first jack. Because the second jack has two, according to two points decide keeping away from of straight line, pass second jack, first jack through two bolts, can realize the fixed of connecting rod promptly. The top end of the rotating shaft is fixedly connected with the rotating disc, so that the rotating shaft can be driven to rotate by manpower conveniently. When the cable well cover is used, the two insertion rods are inserted into the two lifting holes on the cable well cover plate, the metal guide pipe is inserted into a gap at the edge of the cover plate, the cone is positioned right above the gap at the edge of the cover plate, the whole device is pressed downwards, the installation rods are tightly attached to the upper surface of the cover plate, the screw is screwed in, the bottom of the cone is inserted into the gap at the edge of the cover plate, and the nut on the screw is screwed. Then the turntable is driven to rotate, the turntable drives the rotating shaft to rotate, the rotating shaft drives the connecting rod to rotate, the connecting rod drives the cone and the metal guide pipe to rotate along the gap of the edge of the cover plate, so that sundries in the gap are crushed through the cone, the crushed sundries are blown out of the gap through air blown out of the metal guide pipe, and the automatic cleaning process of the gap of the edge of the cable well cover plate is achieved. When encountering a cover plate with a special size, the cone and the metal guide pipe cannot be simultaneously inserted into a gap at the edge of the cover plate, the bolt is discharged, the position of the connecting rod in the axis direction is adjusted, the cone is ensured to be over against the position above the gap, and then the bolt is inserted into the second jack and the first jack again, at the moment, the metal guide pipe is not used, sundries in the gap are only crushed through the cone, and the purposes of quickly cleaning the gap at the edge of the cover plate and facilitating the opening of the cover plate can be achieved. The invention overcomes the problems that when the cover plate is pried by using a crowbar in the prior art, the cover plate can be pried by using a large force due to the blockage of the edge of the cover plate, and the cover plate is easily raised or sunken on the surface of the cover plate in the process and damaged.
