Abstract
The utility model discloses a kind of swabbing pig for bidirectional conveyor adhesive tape, comprise some scraper plates and two steel pipes, what described steel pipe paralleled with adhesive tape pivot center is arranged in below adhesive tape one end, being connected between two steel pipes and being close on the adhesive tape of conveyer by the spring on steel pipe two ends of the inclination that each described scraper plate is parallel to each other, the driving surface of described scraper plate contacts with linear vertical with tape surface, and the front and back end of this scraper plate all adopts circular arc to cut adhesive tape.The inclination that each scraper plate is parallel to each other by the utility model be connected between two steel pipes, the edge of a knife of scraper plate is contacted with linear vertical with tape surface, ensure that the cleaning function of scraper plate during positive and negative operation, and the edge of a knife of scraper plate can not be tangent and expand adhesive tape and to come unstuck scope with the joint of adhesive tape; The front and back end of scraper plate is designed to arc form and adhesive strips contact, and positive and negative operation all can not injure tape splice, adhesive tape originally exist with it come unstuck, ftracture, hole time also can not insert in adhesive tape and tear whole piece adhesive tape accident.
Description
Technical field
The utility model belongs to thermal power plant's belt conveyer accessory equipment, particularly relates to a kind of swabbing pig for removing way traffic band conveyor adhesive tape working area coal.
Background technology
The swabbing pig of belt conveyor machine head in Coal Conveying System of Power Plant, mainly be arranged on below coal spout entrance centre of the drum line, material on adhesive tape parabolically falls into coal spout when arriving this cylinder, the tiny material that adhesive tape is pasted then is swept by the swabbing pig be close on adhesive tape driving surface, fall into too in coal spout, can to keep on adhesive tape driving surface clean like this, tiny material can not enter the stroke and scattering of making the return trip empty of belt feeder on the way with adhesive tape, affect environmental health.But the swabbing pig occurred in the market is all metal or polyurethane swabbing pig, its structure as shown in Figure 3 and Figure 4, scraper plate a is that straight line arrangement is fixed on a round steel pipe b, scraper plate a is surperficial at adhesive tape c by spring force pressure, the most advanced and sophisticated d of scraper plate a is close on adhesive tape c in straight line equally, the centerline parallel of this straight line and cylinder, scraper plate a linearly contacts with adhesive tape c, as colter, the paste of adhesive tape is removed.Because namely belt feeder in coal yard wants windrow feeding again, therefore not only adhesive tape service direction has positive dirction but also have reversing sense, and positive and negative switch frequent.As can be seen from Figure 3, the swabbing pig used at present only possesses the cleaning function in a direction, when adhesive tape inverted running, scraper plate a can be squeezed, and acts on without cleaning, therefore need respectively to install one at frame head and tail cylinder place, ensure no matter be rotate forward or reversion, only have a swabbing pig effective.
But, adhesive tape on current existing thermal power plant belt conveyer still adopts cold vulcanising technique to glued joint in a large number, joint on this adhesive tape always has a service direction to be belong to contra adapter, no matter be rotate forward or reversion, total scraper plate a that once can be subject on swabbing pig injures, there is degumming phenomenon, as shown in Figure 5.Come unstuck when adhesive tape c itself exists, ftracture, the defect such as hole time, the scraper plate a on swabbing pig will expand rapidly the scope of coming unstuck and cause joint breaking, as shown in Figure 6.If scraper plate is fritter composition, fritter scraper plate then can insert in adhesive tape cracking or hole and scratch whole piece adhesive tape, affects the operation of whole coal fired thermal power plant.
Utility model content
The purpose of this utility model is to provide a kind of long-pending coal can removing way traffic band conveyor adhesive tape driving surface, can not injure again the swabbing pig of adhesive tape.
This swabbing pig for bidirectional conveyor adhesive tape that the utility model provides, comprise some scraper plates and two steel pipes, what described steel pipe paralleled with adhesive tape pivot center is arranged in below adhesive tape one end, being connected between two steel pipes and being close on the adhesive tape of conveyer by the spring on steel pipe two ends of the inclination that each described scraper plate is parallel to each other, the driving surface of described scraper plate contacts with linear vertical with tape surface, and the front and back end of this scraper plate all adopts circular arc to cut adhesive tape.
The side of described scraper plate is inclined-plane.
Described scraper plate is made up of high-abrasive material.
The leaning angle of described scraper plate and steel pipe is 55 °.
Described high-abrasive material is 16Mn.
The utility model is connected between two steel pipes by the inclination that is parallel to each other by each scraper plate, the edge of a knife of scraper plate is contacted with linear vertical with tape surface, not only ensure that the cleaning function of scraper plate during positive and negative operation, the edge of a knife also ensuring scraper plate can not be tangent and expand adhesive tape and to come unstuck scope with the joint of adhesive tape; By the front and back end of scraper plate is designed to arc form and adhesive strips contact, no matter be that positive and negative operation all can not injure tape splice, though adhesive tape originally exist with it come unstuck, ftracture, the defect such as hole also can not occur to tear whole piece adhesive tape accident in scraper plate insertion adhesive tape.The utility model structure is simple, reliable, is applicable to the place that two-way belt conveyer adhesive tape exists bonding joint.

Detailed description of the invention
As can be seen from Fig. 1 and Fig. 2, this swabbing pig for bidirectional conveyor adhesive tape of the utility model, comprise some scraper plates 1 and two steel pipes 2, what steel pipe 2 paralleled with the pivot center 4 of adhesive tape 3 is arranged in below adhesive tape one end, the inclination that each scraper plate 1 is parallel to each other be connected between two steel pipes 2, each scraper plate 1 is close on the adhesive tape 3 of conveyer by the spring application on each steel pipe 2 two ends, wherein, the driving surface 11 of each scraper plate 1 contacts with linear vertical with adhesive tape 3 surface, and the front and back end of each scraper plate 1 all adopts circular arc to cut adhesive tape 3.
As can be seen from Figure 2, in the utility model, the side of each scraper plate 1 is inclined-plane.
As can be seen from Figure 2, in the utility model, each scraper plate 1 is 55 ° with the leaning angle of steel pipe 2, but can arrange quantity according to the size of cylinder and scraper plate and change to some extent.
In the utility model, each scraper plate 1 is made up of high-abrasive material, and high-abrasive material is 16Mn.
