Abstract
The utility model belongs to the technical field of a telescopic boom, and relates to an adjustable slide block device for a telescopic boom. The device comprises a basic arm, a telescopic boom and a slide block device, wherein the slide block device comprises a base with an inner thread, an adjusting wheel with an outer thread, and a slide block; the telescopic boom is assembled inside the basic arm; a seat hole is formed in one side of the basic arm; the base is welded into the seat hole; the adjusting wheel is connected with the base through a thread; the slide block is arranged inside a neck at the bottom of the adjusting wheel. The slide block of the device can be installed after the basic arm and the telescopic boom are assembled, so that the assembly process is simple and easy, and time and labor are saved. Meanwhile, the condition that the clearance between the surface of the slide block and the telescopic boom is in a good state can be ensured just by adjusting the adjusting wheel according to the abrasion degree of the slide block, and the slide block can be replaced under the condition of not dismantling the telescopic boom when the slide block loses efficacy, so that the adjustable slide block device is convenient to replace, and time and labor are saved.
Description
Technical field
The utility model belongs to telescopic boom technical field, is specifically related to a kind of telescopic boom adjustable slipper block device.
Background technology
The telescopic boom slide block of the engineer equipments such as current truck-mounted crane, wheel crane, excavating machine is to be mainly connected with basic arm by screw, or slide block is placed in limiting stopper, telescopic boom is in telescopic process, the Surface Contact of shoe surface and telescopic boom and relative motion, when the contact surface work of slide block and telescopic boom often for line contacts, easy to wear, after wearing and tearing, be difficult for maybe cannot adjusting; Slide block lost efficacy while replacing, changed length loaded down with trivial details, consuming time, and the slide block device of bad version has increased the degree of difficulty of basic arm and telescopic boom assembling greatly simultaneously.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of simple in structure, adjustable, long service life, assembling and the easy adjustable slipper block device of replacing.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of telescopic boom adjustable slipper block device, comprises basic arm, telescopic boom and slide block assembly; Slide block assembly comprise be with female pedestal, with externally threaded adjusting knurl, slide block; Telescopic boom is assemblied in basic arm; You Zuo hole, basic arm one end, pedestal is fixed in this hole; Adjusting knurl and pedestal are by thread connection, and slide block is placed in the draw-in groove of adjusting knurl bottom.
The beneficial effects of the utility model are: adjustable slipper block device of the present utility model can be installed after basic arm and telescopic boom assembling again, makes fitting process summary, time saving and energy saving; Only need to adjust adjusting knurl according to slider wear degree, just can ensure that shoe surface and telescopic boom gap are in shape simultaneously; When slide block loses efficacy, without just replaceable slide block of dismounting telescopic boom, it was easy, time saving and energy saving to change.This slide block device is simple in structure, have good using value.
Brief description of the drawings
Fig. 1 is decomposing schematic representation of the present utility model;
Fig. 2 is assembling section of the present utility model;
In figure: 1, basic arm, 2, pedestal, 3, telescopic boom, 4, slide block, 5, adjusting knurl, 6, lock bolt, 7, lubricating cup.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of telescopic boom adjustable slipper block device, comprise basic arm 1, telescopic boom 3 and slide block assembly, telescopic boom 3 is assemblied in basic arm 1, and slide block assembly is by being with female pedestal 2, forming with externally threaded adjusting knurl 5, slide block 4, lock bolt 6 and lubricating cup 7.Basic arm 1 You Zuo hole, one end, pedestal 2 is welded in this hole, has a tapped bore on the sidewall of pedestal 2, and pedestal 2 is with negative thread.Adjusting knurl 5 is with outside thread, and adjusting knurl 5 tops are with rectangular channel, and bottom is with draw-in groove, and there is a through hole at adjusting knurl 5 centers.Slide block 4 is placed in the draw-in groove of adjusting knurl 5 bottoms, adjusting knurl 5 is connected by screw thread with pedestal 2, adjusting knurl 5 is placed in slide block 4 in the space between basic arm 1 and telescopic boom 3, is the distance between adjustable slide 4 and telescopic boom 3 by adjusting the screw-in depth of adjusting knurl 5 in pedestal 2.Lock bolt 6 passes the tapped bore on pedestal 2 and stretches in the rectangular channel on adjusting knurl 5, and to reach the object that prevents that adjusting knurl 5 is loosening, lubricating cup 7 is fixed on the through hole of adjusting knurl 5, so that be slide block 4 grease ups.
Telescopic boom is as follows by the work engineering of adjustable slipper block device:
When telescopic boom 3 was worked after a period of time, lock bolt 6 is dismantled, only need to adjust adjusting knurl 5 screw-in depths according to slide block 4 degree of wears, just can ensure that slide block 4 surfaces are in shape with telescopic boom 3 gaps, and then lock bolt 6 is fixed on pedestal 2 and stretches in the rectangular channel on adjusting knurl 5, to reach the object that prevents that adjusting knurl 5 is loosening, it is simple, convenient to regulate, slide block 4 is fully used, extends the slide block replacement cycle.
In the time that slide block 4 lost efficacy, lock bolt 6 and adjusting knurl 5 are dismantled, the slide block 4 more renewing, new slide block 4 is placed in adjusting knurl 5 bottom draw-in grooves, adjusting knurl 5 and pedestal 2 are connected by screw thread, only need to adjust adjusting knurl 5, just can ensure that slide block 4 surfaces are in shape with telescopic boom 3 gaps, again lock bolt 6 be fixed on pedestal 2 and stretch in the rectangular channel on adjusting knurl 5, to reach the object that prevents that adjusting knurl 5 is loosening, change slide block 4 without dismounting telescopic boom 3, it is simple, convenient, time saving and energy saving to dismantle, install.Lubricating cup 7 is fixed on the through hole of adjusting knurl 5, so that be slide block 4 grease ups, the wearing and tearing that alleviate slide block 4, the life-span of prolongation slide block 4.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; all within principle of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
