Description

Rotary high-pressure jet arch breaking device

Technical Field

The utility model relates to a broken device that encircles of gyration high pressure efflux belongs to the material and carries equipment field technique.

Background

In the modern coal production industry, various coal bunkers are used in a large quantity for temporarily storing coal, and the coal temporarily stored in the coal bunkers is easy to adhere and harden due to certain viscosity and certain moisture content, so that the coal forms a tent bunker arch in the bunkers, and the coal production cannot be normally carried out. In order to solve the problem, a plurality of coal bunker arch breaking devices are developed at home and abroad at present, but the devices have some problems, wherein the most important problem is that the existing arch breaking device has a limited action range, so that when high arch camber occurs in a coal bunker, the action range of the arch breaking device cannot reach an arch camber position, and arch breaking operation cannot be normally carried out. In order to solve the problem, the patent No. ZL201811484648.5 filed by the inventor proposes a hydraulic mechanical combined arch breaking device, which breaks the arch through high-pressure water injection and a hydraulic material poking device and has the advantages of large arch breaking range and good arch breaking effect, but the arch breaking device also has a problem in the use process, namely a water spray head of the arch breaking device is fixed at the circumferential position of the arch breaking device, so that the water spray surface of the arch breaking device can only be one point and at most one limited surface in arch breaking, and the arch breaking effect cannot achieve the best effect, and therefore a new technical scheme needs to be adopted to overcome.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing such a device is encircleed to gyration high-pressure jet, it can solve the aforesaid problem that the device exists of encircleing effectively.

The purpose of the utility model is realized like this: the utility model provides a broken device that encircles of gyration high-pressure efflux, contains actuating cylinder, guide rail, leading wheel, broken cover, sprinkler bead, actuating cylinder bottom is connected on the support, the guide rail is the spiral form and connects on actuating cylinder's the cylinder outer wall, broken cover suit is in on the guide rail, broken cover comprises inner tube and urceolus, is for leading to the water chamber between inner tube and the urceolus, and its lower extreme is connected with the inlet tube, and the upper end is sealed by the apron be provided with on the apron and lead to the water chamber and link to each other the sprinkler bead, actuating cylinder's piston rod is connected on the end cover, actuating cylinder's piston rod with broken cover connection that encircles, the leading wheel is installed broken cover lower part, and the interpolation dress is in between the guide rail.

The guide wheel comprises a support shaft and a pulley, one end of the support shaft is connected to the arch breaking sleeve, the other end of the support shaft is of a suspended structure, and the pulley is mounted at the end part of the support shaft.

The number of the guide rails is not less than 3, and the number of the guide wheels is at least two less than that of the guide rails.

The outer diameter of the pulley is smaller than the distance between two adjacent guide rails in the plane direction.

The helix angle of the helical guide rail is 45-75 degrees.

The number of the sprinkler heads is 2-4.

The cylinder barrel of the driving oil cylinder is connected to the support, and the piston rod is connected with the end cover of the arch breaking sleeve, so that the arch breaking sleeve can be driven to move up and down when the driving oil cylinder moves, and the arch breaking sleeve enters the coal bunker to mechanically break an arch. Meanwhile, high-pressure water can be sprayed in the coal bunker through the water spray heads arranged on the end covers, so that arch breaking of jet flow is achieved. Set up spiral helicine guide rail in the outside of actuating cylinder, and set up the leading wheel of cartridge between the guide rail in broken telescopic lower part that encircles, when broken sleeve appearance actuating cylinder reciprocates like this, under the guide effect of leading wheel, can follow cylinder circumference rotation, make the sprinkler bead of installing on broken sleeve end cover rotatory thereupon, the spray regime of sprinkler bead is compared in original point face effect and is become the broken scope of encircleing of three-dimensional clearance in whole space like this, the broken effect of encircleing of sprinkler bead has been improved greatly, the broken problem that encircles the device existence of original efflux has been solved, and has obvious advantage.

When the broken sleeve of encircleing around the rotatory in-process of drive hydro-cylinder, the rotatory power of the broken sleeve of encircleing of drive is mainly provided by the leading wheel, consequently, there is great frictional force between leading wheel and the guide rail, the leading wheel comprises back shaft and pulley, back shaft one end is connected on the broken sleeve of encircleing, the other end is unsettled structure, the pulley is installed to the tip, like this, when the leading wheel removed along the guide rail, the interact between the two becomes rolling friction by sliding friction, frictional force greatly reduced can guarantee the telescopic smooth motion of broken encircleing effectively.

Because the arch breaking sleeve moves and rotates along the guide rail, the number of the guide rails is not less than 3, the contact area between the inner wall of the arch breaking sleeve and the outer surface of the guide rail is increased, and the arch breaking sleeve has an important effect on ensuring the stable motion of the arch breaking sleeve. In the arch breaking process, the guide wheels move between the guide rails, and the oil pipes of the arch breaking oil cylinders are also installed between the guide rails, so that the number of the guide wheels is at least two less than that of the guide rails in the design process, the problem of rotary movement of the arch breaking sleeve is solved, and the problem of installation of the oil pipes is also solved.

The arch breaking sleeve rotates in the process of moving up and down, the outer diameter of the pulley is smaller than the distance between two adjacent guide rails in the plane direction, when the arch breaking sleeve moves upwards, the pulley contacts with the side face of one guide rail, and when the arch breaking sleeve descends, the pulley contacts with the other side face, so that when the arch breaking sleeve moves upwards, the sprinkler head is in one spraying direction, when the arch breaking sleeve descends, the sprinkler head is in the other spraying direction due to the fact that the pulley contacts with the side face of the other guide rail, the design increases the action range of the sprinkler head, and the arch breaking sleeve has the obvious advantage.

The helix angle of the guide rail has great influence on the rotation driving force of the arch breaking sleeve and the action range of the sprinkler head, the larger the helix angle is, the smaller the rotation driving force is, but the smaller the action range of the sprinkler head is, the helix angle of the spiral guide rail is between 45-75 degrees, so that the rotation driving force can be considered, and the action range of the sprinkler head can be considered.

Because the water passing cavity is formed between the inner cylinder and the outer cylinder of the arch breaking sleeve, the water passing area of the water passing cavity is large, the water spraying area can be increased, the area of a single sprinkler head is too large, the sprinkler head water spraying speed of the sprinkler head is increased disadvantageously, the number of the sprinkler heads is 2-4, the water spraying speed can be guaranteed, the action range of the sprinkler head can be increased, and the arch breaking effect is improved.
