Abstract
The utility model relates to an auxiliary coal mine transporting device-a single-track hanger, particularly a single-track hanging pulley which is composed of two special-shaped wheels (2), thrust bearings (1), wheel shafts (5), a cross beam (3) and connecting pieces. The two special-shaped wheels (2) are pulleys of which the upper sides are provided with rims, and the two special-shaped wheels (2) are arranged on two wheel shafts (5) through thrust bearings (1); the upper ends of the two wheel shafts (5) are provided with shaft shoulders, and the lower ends of the two wheel shafts (5) are arranged in shaft holes of both ends of the cross beam (3) and are connected with the cross beam (3) through fixing nuts (4) or pin shafts. The utility model has the advantages of simple structure, light weight and convenient, simple and rapid installation and disassembly and is not easy to clamp at the connecting point of hanging tracks of the single-track hanger. The utility model is suitable for hanging cables along grooves on coal faces.
Description
Affiliated technical field
The utility model relates to down-hole, mine auxiliary conveying equipments monorail crane, the monorail crane pulley on particularly a kind of monorail crane.
Background technology
The crossheading cable of coal mine fully-mechanized mining working needs move along with the propelling of work plane, and at present effective method is to use the monorail crane suspended cables.But the monorail crane pulley is introduced domesticly so far over more than 20 year since combining to adopt, and its structure never changed because original monorail crane pulley structure complexity, use inconvenient.Be in particular in: 1. being made up of four pulleys, is monolithic construction, and non-dismountable, volume is big, and weight is big, moves inconvenient.2. monorail crane is not had constraint in the horizontal direction, cause in monorail crane i-beam track joint easily to be stuck.
Summary of the invention
For solve existing monorail crane pulley structure complexity, weight big, non-dismountable, use problem such as inconvenience, the utility model provide a kind of simple in structure, in light weight, remove and install monorail crane pulley convenient and swift, be difficult for being stuck, being fit to the production scene needs at the rail joint place.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
The monorail crane pulley is made up of the pulley, thrust bearing, wheel shaft, crossbeam and the connector that roll along i-beam track.Its pulley is only used two, and is special-shaped wheel.Two special-shaped wheels are pulleys that upside has wheel rim, and they are contained in respectively on two wheel shafts by thrust bearing.There is the shaft shoulder upper end of two axles, and the lower end is assemblied in respectively in the axis hole at crossbeam two ends and by connector and crossbeam and is fixedly connected.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted can also be:
Screw thread and hold-down nut and the crossbeam of the lower end of monorail crane pulley two axles by its axle head is fixedly connected.
The lower end of monorail crane pulley two axles is fixedly connected by bearing pin and the crossbeam that is loaded in its axle head pin-and-hole.
The beneficial effects of the utility model are:
1. simple in structure, in light weight, be difficult for being stuck in the monorail crane joint.
2. mounting or dismounting are changed and are added that to remove the monorail crane pulley very convenient simply, easily and fast.Be fit to the production scene needs.
Description of drawings
Accompanying drawing is the structural representation front view of the utility model monorail crane pulley
Among the figure: 1-thrust bearing, the special-shaped wheel of 2-, 3-crossbeam, 4-hold-down nut, 5-wheel shaft
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further.
As shown in drawings, the utility model is made up of two special-shaped wheel (2), thrust bearing (1), wheel shaft (5), crossbeam (3) and hold-down nuts (4).Two special-shaped wheels (2) have the pulley of wheel rim for upside, and they are contained in respectively on two wheel shafts (5) by thrust bearing (1).There is the shaft shoulder upper end of two axles (5), and match with the axis hole at crossbeam (3) two ends in the lower end, its axle head is threaded.Two axles (5) lower end is assemblied in the axis hole at crossbeam (3) two ends, and by hold-down nut (4) and fastening connection of crossbeam (3) on the axle head screw thread.
Between the lower end and crossbeam (3) of special-shaped wheel wheel shaft (5), except adopting the thread connector connection, also can adopt pin type to connect, promptly be connected and fixed, to realize the Fast Installation dismounting by the bearing pin in the axle stub pin-and-hole.
The utility model is compared Yu the single-track hanging pulley of existing four pulley structures, and Zhu will improve 3 points:
1. change four pulley structures into two pulley structures, alleviated the Chong amount.
2. ordinary wheel is changed into special-shaped wheel (2), monorail crane is carried out up and down and the Yue of horizontal both direction bundle, Prevent that single track is hung in the i-beam track joint and blocks.
3. two special-shaped wheel wheel shafts (5) connect by screw and crossbeam (3), and Zhi will twist off hold-down nut (4) namely Detachable lower different type wheel (2) is so that this pulley dismounting is very convenient. Connect for pin type, Zhi will pull down wheel Bearing pin in the pin hole can be realized dismounting.
Claims (3)
1. monorail crane pulley comprises the pulley that rolls along i-beam track, it is characterized in that: said pulley has only two and be special-shaped wheel (2); Two special-shaped wheels (2) are the pulleys that upside has wheel rim, and they are contained in respectively on two wheel shafts (5) by thrust bearing (1); There is the shaft shoulder upper end of two axles (5), and the lower end is assemblied in respectively in the axis hole at crossbeam (3) two ends and by connector and crossbeam (3) and is fixedly connected.
2. monorail crane pulley according to claim 1 is characterized in that: the connector that the lower end of said two axles (5) and crossbeam (3) are fixedly connected is the hold-down nut (4) on its axle head screw thread.
3. monorail crane pulley according to claim 1 is characterized in that: the connector that the lower end of said two axles (5) and crossbeam (3) are fixedly connected is the bearing pin that is loaded in its axle head pin-and-hole.
