Abstract
Description
Technical Field
[0001] This utility model relates to the field of rock loading machine technology, and more specifically, to a rock loading machine bucket positioning device. Background Technology
[0002] A rock loader is a type of loading equipment used in underground mines. Its purpose is to load ore or rock into transport equipment. The commonly used bucket-type rock loader moves forward while the body moves forward, the bucket moves down and inserts into the rock pile, then the bucket is raised and the machine moves backward. The bucket overturns the rock into the mine car or other transfer equipment attached to the back of the machine. It is a special loading equipment for underground mine roadways that loads from the front and unloads from the rear.
[0003] A search revealed that utility model patent CN212926235U discloses a positioning device for a rock-loading machine bucket, including a lifting mechanism, a lever, a support rod, and a brake band. The lifting mechanism is mounted on the upper seat plate of the rock-loading machine. A support column is provided between the lifting mechanism and the brake disc. A lever is rotatably mounted on the top surface of the support column. One end of the lever is rotatably connected to the end of the telescopic rod of the lifting mechanism, and the other end of the lever is fixedly connected to one end of the brake band. The brake band is sleeved around the brake disc, and the other end of the brake band is fixedly connected to the support column. This patent enables the rock-loading machine bucket to be positioned at any location.
[0004] However, the above-mentioned patent still has the following shortcomings: when the brake band is loosened and positioning is not performed, the brake disc will also wear the brake band, affecting the service life of the brake band; and during the braking process, both the brake band and the brake disc will generate a certain amount of brake dust. Excessive brake dust can easily cause the brake disc temperature to rise, affecting the heat dissipation efficiency of the braking system and thus reducing braking performance. Therefore, we have proposed a positioning device for a rock loading machine bucket. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a positioning device for the bucket of a rock loading machine.
[0006] To solve the above problems, the present invention adopts the following technical solution:
[0007] A positioning device for a rock-loading machine bucket includes a base plate, a brake box fixedly connected to the top of the base plate, a reducer installed on the top of the base plate, a drive motor installed on the top of the base plate, the output shaft of the drive motor connected to the input shaft of the reducer, a drive shaft fixedly connected to the output shaft of the reducer, the end of the drive shaft penetrating the inner cavity of the brake box and extending to the outside of the brake box, a brake disc fixedly sleeved on the outside of the drive shaft and located in the inner cavity of the brake box, a dust removal mechanism installed on the brake box, multiple sets of electro-hydraulic rods fixedly installed on both sides of the inner cavity of the brake box, the output ends of the multiple sets of electro-hydraulic rods fixedly connected to mounting seats, mounting blocks installed on the multiple mounting seats, and brake pads provided on the sides of the mounting blocks.
[0008] As a preferred embodiment of this utility model, the dust removal mechanism includes a collection box fixedly connected to the top of the brake box, a blower pipe fixedly sleeved on the bottom surface of the collection box, the bottom end of the blower pipe extending into the inner cavity of the brake box and fixedly sleeved with a blower box, the bottom surface of the blower box having multiple blower holes, a filter screen fixedly sleeved in the inner cavity of the collection box, an exhaust pump fixedly installed on the side of the collection box, the output end of the exhaust pump extending into the inner cavity of the collection box, an exhaust pipe fixedly connected to the output end of the exhaust pump, the bottom end of the exhaust pipe extending into the inner cavity of the brake box and fixedly connected with a dust collection cover, the dust collection cover being located directly below the brake disc.
[0009] As a preferred embodiment of this utility model, the mounting block is provided with multiple screw holes, the mounting base is provided with multiple mounting holes, and bolts are fitted into the inner cavities of the multiple mounting holes, with the ends of the bolts threaded into the inner cavities of the screw holes.
[0010] As a preferred embodiment of this utility model, the brake box is hinged with a material changing door on each side.
[0011] As a preferred embodiment of this utility model, a controller is fixedly installed on the top surface of the brake box.
[0012] As a preferred embodiment of this utility model, the side of the collection box is hinged with a sealing door.
[0013] Compared with existing technologies, the advantages of this utility model are:
[0014] (1) In this utility model, the bucket is driven to move by the cooperation of the drive motor, reducer and drive shaft. At the same time, the drive shaft drives the brake disc to rotate. When the bucket of the rock loader is positioned, the mounting seat, mounting block and brake pads are moved by multiple electric hydraulic rods. The brake pads on both sides of the brake disc are squeezed to make the brake pads squeeze and lock the brake disc, so that the bucket of the rock loader is positioned and suspended in any working position.
[0015] (2) In this utility model, the suction force generated by the exhaust pump is generated by the exhaust pipe and the dust collection hood. At the same time, the input end of the exhaust pump blows air into the inner cavity of the collection box. The air force in the inner cavity of the collection box enters the blower box and blows the air force in the blower box from the blower hole onto the brake disc and brake pads, thereby blowing down the brake powder on the brake disc and brake pads. The suction force of the dust collection hood is used to suck the brake powder into the inner cavity of the collection box. The filter screen is used to intercept and collect the brake powder, thus realizing the function of cleaning the brake powder on the brake disc and brake pads. It has good practicality.
