Abstract
The utility model discloses a mounting and maintenance device for a variable-amplitude oil cylinder of a lorry-mounted crane. The mounting and maintenance device comprises a base and a bracket, wherein the bracket is fixed on the base through a reinforcement plate; pedals are welded on the upper part, the middle part and the lower part of the bracket; an oil cylinder fixing block is arranged on the upper part of the bracket; a pin and an oil cylinder fixing bolt are arranged on the oil cylinder fixing block; an oil cylinder fixing plate and a hand shank are arranged at the end of the oil cylinder fixing bolt; one end of an oil cylinder fixing lug is fixed on the base; the other end of the oil cylinder fixing lug is fixed on the bracket; and a pin shaft is arranged on the middle part of the oil cylinder fixing lug. The mounting and maintenance device has the advantages that: the pin on the oil cylinder fixing block can be adjusted according to the size of the variable-amplitude oil cylinder so as to be suitable for various variable-amplitude oil cylinders; the bottom of the oil cylinder is fixed by the pin shaft; during mounting and maintenance, the variable-amplitude oil cylinder can be prevented from rotating; the variable-amplitude oil cylinder is vertically arranged, so that the condition that internal parts of the oil cylinder enter the oil cylinder can be seen clearly and intuitively; abrasion to the internal sealing pieces of the oil cylinder is reduced during mounting and maintenance; and potential safety hazard can be further reduced.
Description
[technical field] the utility model relates to automobile mechanical, specifically a kind of installation and maintenance device of lorry-mounted crane amplitude oil cylinder.
[background technology] is along with the development of nation-building, and be increasing for the demand of engineering machinery construction equipment, and truck with loading crane can fast lifting; Mobility is good; Have advantages such as flexible, light, safe, reliable, be received by the market very much, its output and sales volume are also soaring thereupon.Amplitude oil cylinder is the vitals of lorry-mounted crane, is mainly used in the rising and the decline of control arm, because frequency of utilization is very high, makes the seal of amplitude oil cylinder very easily wear and tear, and need change at regular intervals; And amplitude oil cylinder is that cylindrical structural and quality are bigger, and is difficult fixing also not quick detachable when installation and maintenance, also has certain potential safety hazard.
The potential safety hazard that [summary of the invention] the utility model pin exists when solving the amplitude oil cylinder installation and maintenance provides a kind of installation and maintenance device of lorry-mounted crane amplitude oil cylinder.
The installation and maintenance device of this lorry-mounted crane amplitude oil cylinder; Comprise fixedly ear of pedestal, support, oil cylinder fixed block, oil cylinder fixed head and oil cylinder, it is characterized in that, pedestal is fixed on the ground through foundation bolt; Pedestal is provided with stiffener, and stiffener is fixed on support on the pedestal; The upper, middle and lower portion of support is welded with pedal, and the both sides of top pedal are provided with tool shelf; Support top also is provided with the oil cylinder fixed block, and the oil cylinder fixed block is provided with latch and oil cylinder set bolt, and oil cylinder set bolt end is provided with oil cylinder fixed head and handle; An oil cylinder fixedly end of ear is fixed on the pedestal, and the oil cylinder fixedly other end of ear is fixed on the support, and oil cylinder fixedly is provided with bearing pin in the ear middle part.
The amplitude oil cylinder of needs installation or maintenance vertically is placed on the oil cylinder fixed block outside of base seat support; Size according to amplitude oil cylinder; Select suitable latch on the oil cylinder fixed block; Fixedly ear middle part insert bearing pin and make that the amplitude oil cylinder bottom is fixing at oil cylinder then, through the handle on the rotary oil cylinder set bolt oil cylinder fixed head is fixed the top of amplitude oil cylinder, the Installation and Debugging back workman that finishes may stand in the enterprising line operate of pedal.
The beneficial effect of the utility model is: the latch on the oil cylinder fixed block can make device all be suitable for various amplitude oil cylinder according to the size adjustment of amplitude oil cylinder; The oil cylinder bottom is fixed through bearing pin, in the installation and maintenance process, can avoid the rotation of amplitude oil cylinder; Because amplitude oil cylinder be vertically to place, cooperate caravan in the installation and maintenance process, the situation in the time of seeing the oil cylinder internal part intuitively clearly and enter into oil cylinder, thus reduced the wearing and tearing of oil cylinder inner seal in installation and maintenance process, can also reduce potential safety hazard.
