Abstract
The utility model belongs to the technical field of hydraulic supports, in particular to a movable adjustable connector, the end part of which is movably connected with a connecting rod, and one end of the connecting rod away from the connector is connected with a push rod; one end of the connector, which is far away from the connecting rod, is movably connected with the lug plate of the scraper conveyor. After the movable adjustable connector is adopted, the types of the connector molds are reduced, the requirement of different center distances can be met by using one mold, and the mold manufacturing cost is greatly reduced.
Description
Technical Field
The utility model belongs to the technical field of hydraulic support, concretely relates to connector with adjustable activity.
Background
At present, a coal mine hydraulic support is connected with a transportation equipment scraper machine through a connector, one end of the connector is connected with a hydraulic support pushing rod, and the other end of the connector is connected with the scraper machine. The hydraulic support connector is mainly used for organically connecting the underground hydraulic support of the coal mine with the scraper conveyor, so that force transmission between the underground hydraulic support and the scraper conveyor is realized, and pushing, sliding and pulling of the support are completed. The connector bears the alternating stress of tension, compression and torsion during working, and the stress condition is deteriorated due to the environment difference of the working surface, so that the connector is very easy to deform and break, and once the connector is damaged, the scraper conveyor and the hydraulic support can not work normally, so that the connector becomes a vulnerable stress part on the hydraulic support, and the connector is replaced frequently and has large use amount.
The existing connectors are welded, cast and forged. The welding connector is mainly used for a bracket with small work resistance, a casting and a forging are basically used for the bracket with large work resistance, but the casting is changed into a forging process because the strength of the casting cannot meet the requirement, a forming die is required for forging, and the manufacturing cost of the die is high. The hydraulic support is limited by the matching of three machines, the hydraulic support with the same frame type is used in different mines, and connectors with different center distances need to be used to meet the matching requirements of the support and the scraper conveyor, so that the types of the connector molds are increased, and the cost is increased.
Disclosure of Invention
In order to overcome the shortcomings of the prior art, the utility model provides a connector with adjustable activity increases a section of connecting rod on the basis of original connector mould, can realize the center-to-center distance adjustment.
The utility model discloses a realize through following technical scheme: the end part of the connector is movably connected with a connecting rod, and one end of the connecting rod, which is far away from the connector, is connected with a push rod; one end of the connector, which is far away from the connecting rod, is movably connected with the lug plate of the scraper conveyor.
Furthermore, the tip of connector is equipped with the round pin shaft hole, and the tip that the connector was equipped with the round pin shaft hole still is equipped with and runs through the recess in round pin shaft hole also is equipped with the through hole on the connecting rod, and in the connecting rod stretched into the recess of connector, the round pin axle inserted the round pin shaft hole and the through hole of connecting rod with connector and connecting rod activity hinge together.
Furthermore, the connecting rod and the push rod are movably hinged together through a pin shaft.
The utility model has the advantages that: after the movable adjustable connector is adopted, the types of the connector molds are reduced, the requirement of different center distances can be met by using one mold, and the mold manufacturing cost is greatly reduced.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure, 1, a connector, 1-1, a pin shaft hole, 2, a push rod, 3, a scraper blade lug plate, 4 and a connecting rod.
Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in figure 1, the end of the connector 1 is movably connected with a connecting rod 4, the end of the connector 1 is provided with a pin shaft hole 1-1, the end of the connector 1 provided with the pin shaft hole is also provided with a groove penetrating through the pin shaft hole 1-1, the connecting rod 4 is also provided with a through hole, the connecting rod 4 extends into the groove of the connector 1, the through hole of the connecting rod 4 is communicated with the pin shaft hole 1-1, and a pin shaft is inserted into the pin shaft hole 1-1 and the through hole of the connecting rod 4 to realize the movable hinge joint of the connector 1 and the connecting rod 4. One end of the connecting rod 4, which is far away from the connector 1, is connected with the push rod 2, the connecting rod 4 and the push rod 2 are movably hinged together through a pin shaft, and bolts are radially inserted into two ends of the pin shaft to prevent the pin shaft from falling off. One end of the connector 1 far away from the connecting rod 4 is movably connected with the scraper conveyor ear plate 3.
This application realizes scraping the regulation of trigger and support interval distance through the connecting rod of changing different length L. Compared with the prior art, the connector mould type is reduced in this application, and the requirement that different centre-to-centre distances can be satisfied to a mould, greatly reduced mould manufacturing cost.
