Abstract
The invention discloses a rotary lubricating structure for a guardrail breakdown van. The rotary lubricating structure comprises a gear column, a base body and a rack. The gear column is inserted in the base body. Thrust washers are arranged between step faces on the lower portion of the base body and the gear column. A limiting pin is arranged on the side wall of the base body. A threaded hole is formed in the limiting pin. An oil cup is connected with the limiting pin through the threaded hole. A gap is reserved between the part, below the limiting pin, of the gear column and the base body. A sliding block is fixed to the inner wall of the base body. The rack is arranged in the position between a gear of the gear column and the sliding block. The rack is meshed with the gear of the gear column. Due to the fact that the structure of the gear column and the structure of the inner wall of the base body provided with the gear column are changed, the lubricating function between the rack and the gear column can be achieved; and lubricating grease is injected through the oil cup and can enter a rotation mechanism. The rotating lubricating structure is simple, low in cost, low in requirement for lubricating sealing performance while lubricating is ensured and capable of achieving later-stage lubricating maintaining.
Description
Technical field
The present invention relates to a kind of lubricating structure, be specifically related to a kind of for guard rail breakdown van revolution lubricating structure.
Background technique
Along with the fast development of communications and transportation, the total amount of traffic accident also increases day by day, wherein, part traffic accident can cause the damage of road guardrails of both sides plate and guardrail pile, and road maintenance department has a responsibility for the maintenance and the replacing operation that complete damage guardrail pile and interior paneling at the appointed time.
Guard rail breakdown van all carries out operation in the side of vehicle usually, and in order to the safety of running process, apparatus for work is all placed on directly over vehicle in the process of moving, so guard rail breakdown van has swirl gear.The swirl gear of guard rail breakdown van common by two kinds of forms: oil cylinder with gear racks structure and Slewing Support Mechanism.The swirl gear of oil cylinder with gear racks structure has simple, the with low cost and angle of revolution of structure can be undertaken the advantage such as limiting by the stroke of oil cylinder with gear racks, and the guard rail breakdown van of part adopts this kind of revolving structure.This structure is disposable coating lubricating oil when gear and tooth bar assembling, cannot realize lubrication during later maintenance, causes tooth bar and tooth bar wearing and tearing aggravation, produces abnormal sound in turning course.At present, the domestic lubrication to this kind of structure rack and pinion does not also have effective method.The external mode of oil lubrication that usually adopts solves, assembling before in the installing space of gear charging-up lubricant oil, lubricant oil liquid level exceeds rack and pinion engagement upper end portion certain distance, but this kind of lubricating system is very large to the sealing requirements of element, cost is higher, is difficult at home realize this lubricating system.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of for guard rail breakdown van revolution lubricating structure, structure is simple, and cost is low, can realize later stage lubricated maintenance.
To achieve these goals, the technical solution used in the present invention is: a kind of guard rail breakdown van that is used for turns round lubricating structure, comprise Cylindrical Gear, base body, tooth bar, Cylindrical Gear is inserted in base body inside, on the ladder surface of base body bottom and between Cylindrical Gear, thrust washer is set, base body sidewall is provided with position limit pin, position limit pin there is tapped hole, lubricating cup is connected with position limit pin by tapped hole, gap is left between position limit pin bottom cog post and base body, slide block is fixed on base body inwall, tooth bar is arranged on the position between Cylindrical Gear gear and slide block, rack and pinion stud wheel engages.
Further, the upper and lower of described base body is provided with lubricating bushings.
Further, described Cylindrical Gear offers annular groove, groove is positioned at above gear, and the position of groove and the position of position limit pin adapt.
The invention has the beneficial effects as follows: by changing the structure of the base body inwall of Cylindrical Gear and installation Cylindrical Gear to realize the lubricating function between rack and pinion post, by lubricating cup grease up, lubricating grease can enter swirl gear inside, structure is simple, cost is lower, not high to the sealing requirements of lubrication while ensureing lubrication, later stage lubricated maintenance can be realized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the enlarged diagram of I in Fig. 1;
In figure: 1, Cylindrical Gear, 2, lubricating cup, 3, position limit pin, 4, base body, 5, lubricating bushings, 6, thrust washer, 7, tooth bar, 8, slide block.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, this is used for guard rail breakdown van revolution lubricating structure, comprise Cylindrical Gear 1, base body 4, tooth bar 7, it is inner that Cylindrical Gear 1 is inserted in base body 4, on the ladder surface of base body 4 bottom and between Cylindrical Gear 1, thrust washer 6 is set, base body 4 sidewall offers tapped hole, position limit pin 3 is screwed into base body 4 from the tapped hole base body 4 sidewall, position limit pin 3 also there is tapped hole, lubricating cup 2 is connected with position limit pin 3 by the tapped hole on position limit pin 3, gap is left between position limit pin 3 bottom cog post 1 and base body 4, slide block 8 is fixed on base body 4 inwall, tooth bar 7 is arranged on the position between Cylindrical Gear 1 gear and slide block 8, tooth bar 7 and Cylindrical Gear 1 gears meshing.
Lubricating grease is added from lubricating cup 2, lubricating grease down moves along the gap between Cylindrical Gear 1 and base body 4, be full of the space between thrust washer 6 and Cylindrical Gear 1 gear top, the lubricating grease added from lubricating cup 2 is by the surface of contact between the hole lubrication slide block 8 on slide block 8 and tooth bar 7, reduce the frictional force of tooth bar 7 in slipping, Cylindrical Gear 1 offers annular groove, annular groove is positioned at above gear, the position of annular groove and the position of position limit pin 3 adapt, the head of position limit pin 3 to go deep in annular groove and and the lower contacts of annular groove, prevent in traveling and operation process because impact and the Cylindrical Gear 1 caused that jolts move upward, prevent between Cylindrical Gear 1 and thrust washer 6, producing the leakage that gap causes lubricating grease.The upper and lower of base body 4 is provided with lubricating bushings 5, is reduced between turning course middle gear post 1 and base body 4 inwall and weares and teares.
