Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, the utility model discloses a crane pipe, include: the device comprises a fixed column 1, a cantilever 2, a pull rod 3, a first pipeline 4, a proximity sensor 6, a piston rod 7, a bolt movable rod 8, a second pipeline 9 and an insertion pipe 11.

The upper end of cantilever 2 is fixed on fixed column 1, and is preferred, a fixed block of welding on the outer wall of fixed column 1, set up on the fixed block with 2 appearances of cantilever unanimous and than the mounting hole that 2 appearances of cantilever are little, it is used for with 2 joints of cantilever on fixed column 1.

One end of the first pipeline 4 is fixedly connected with the lower end of the cantilever 2. Preferably, the lower end of the boom 2 is welded to the first pipe, and the welded first pipe 4 is at a right angle of 90 ° to the boom 2.

The other end that is connected at first pipeline 4 and cantilever 2 is equipped with second pipeline 9, sets up intubate 11 at the other end that second pipeline 9 and cantilever 2 are connected, and first pipeline 4, second pipeline 9 and intubate 11 are inside to be linked together.

The proximity sensor 6 is fixedly arranged on the outer wall of the second pipeline 9, and the electric wire of the proximity sensor 6 is connected in series with the electric wire of the start button for discharging the tank car. Preferably, a bracket is welded on the outer wall of the second pipeline 9, the bracket is provided with a plurality of bracket holes, when the bolt movable rod 8 is inserted into one of the limiting holes, one end of the bolt movable rod is connected with the terminal end of the piston rod 7, and the other end of the bolt movable rod abuts against the proximity sensor 6. The proximity sensor 6 is installed beside the bracket hole, when the bolt movable rod 8 is inserted into one of the limiting holes, the proximity sensor 6 contacts with the bolt movable rod 8, senses the existence of the bolt movable rod 8, and converts the signal into an electric signal (on-off), so that the electric wire circuit of the proximity sensor 6 is communicated, and the starting button circuit has a starting condition.

The piston rod 7 is fixed on the outer wall of the second pipeline 4 and can charge air into the crane pipe. When the piston rod 7 inflates the oil filling riser, the flow speed of fluid in the oil filling riser can be increased, and therefore the working efficiency of the oil filling riser is improved.

As a preferred scheme of the present invention, a first elbow 5 is disposed between the first pipeline 4 and the second pipeline 9, and the first elbow 5 makes the first pipeline 4 and the second pipeline 9 perpendicular to each other; a second bend 10 is provided between the second conduit 9 and the cannula 11, the second bend 10 being such that the second conduit 9 and the cannula 11 are perpendicular.

As another preferable scheme of the present invention, a pull rod 3 is disposed between the upper portion of the cantilever 2 and the first pipeline 4, and the pull rod 3, the first pipeline 4 and the cantilever 2 form a triangle structure, so as to increase the stability of the whole crane pipe structure.

The use of the invention is further described below by means of an embodiment:

will the utility model discloses insert bolt movable rod 8 after the intubate 11 of oil filling riser inserts the tank car, proximity sensor 6 received the insertion signal who comes from bolt movable rod 8 this moment, and proximity sensor 6 transmits the blowing start button for the tank car after will inserting signal conversion to the signal of telecommunication, presses start button this moment, and the tank car begins the blowing. When the staff forgets to insert the plug pin movable rod 8, the proximity sensor 6 does not detect an insertion signal, and the tank car emptying starting button is pressed, so that the emptying process cannot be started. Insert bolt movable rod 8 and be the last operation before the tank car blowing, through set up proximity sensor 6 and bolt movable rod 8 in the second pipeline 9 outside and come indirect detection oil filling riser intubate 11 and insert the tank car in to reach and stop because of inserting the oil filling riser the incident of direct blowing in the tank car, and this simple structure, the cost of manufacture is lower has very big practicality.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
