Abstract
The utility model discloses a caterpillar belt span adjusting device. The adjusting device comprises a base (1) and support rods (2) are symmetrically arranged on the two sides of the base (1). Two ends of the support rod (2) are respectively articulated with the base (1) and a caterpillar belt bracket (4) and a hydraulic cylinder (3) is arranged between the support rod (2) and the base (1). The hydraulic cylinder is used in the utility model for adjusting caterpillar belt span so as to ensure that the track span of a caterpillar machine can be adjusted smoothly and stably, therefore the machine can adapt to more complicated road surface. In addition, the caterpillar belt is made of rubber and no damage is caused when the machine is driven in the road, thereby facilitating the requirementof machine transfer.
Description
Technical field
The utility model relates to a kind of crawler belt span control apparatus.
Background technology
Need be for some at the machinery of soft surface or complex road surface walking, as tank, trac., excavating machine etc. use the mode of cterpillar drive usually.Present crawler belt is to make with iron and steel substantially, is not suitable for travelling at cement pavement or asphalt surface, and the transfer of these machineries has been caused difficulty.Also have, the span of crawler belt is substantially all fixed at present, some are applied to the crawler belt machinery in nursery especially, because some spacing of the forest of planting in the nursery is very narrow, crawler belt machinery can't enter and construct, therefore be necessary to design the small-sized caterpillar belt machinery that a kind of crawler width can be regulated, to adapt to the walking requirement of nursery, mountain region and various landform.
The utility model content
The purpose of this utility model is, a kind of crawler belt span control apparatus is provided, and can freely adjust the crawler belt span, to adapt to more landform, is specially adapted to the small-sized caterpillar belt formula walking machine in the nursery construction.
The technical solution of the utility model: a kind of crawler belt span control apparatus, the formation of this device comprises base, and the base bilateral symmetry is provided with strut bar, and the strut bar two ends are hinged with base and crawler belt support respectively, are provided with hydraulic actuating cylinder between strut bar and the base.
In the above-mentioned crawler belt span control apparatus, the bottom of described base is provided with boss, and strut bar and hydraulic actuating cylinder are hinged on the boss.
In the aforesaid crawler belt span control apparatus, described boss both sides are hinged with pair of support rods respectively.
In the aforesaid crawler belt span control apparatus, described boss both sides are provided with groove.
In the aforesaid crawler belt span control apparatus, the piston rod of described crawler belt support and hydraulic actuating cylinder is hinged.
In the aforesaid crawler belt span control apparatus, described crawler belt support is provided with at least two Athey wheels, and Athey wheel is connected with cterpillar drive.
In the aforesaid crawler belt span control apparatus, described crawler belt is made with rubber.
Compared with prior art, the crawler belt span of prior art is generally unadjustable, for the both sides, road surface the house is arranged, and, or can't walk in the forest gap in nursery less than crawler belt span lane as width.The utility model adopts hydraulic efficiency gear to regulate the crawler belt span, makes the crawler belt span of crawler type traveling machine can free adjustment, to adapt to more complicated road surface.Existing in addition crawler belt, usually adopt iron and steel to make, this crawler belt made from iron and steel is not allow to travel at the cement pavement or the asphalt surface in city, because the iron and steel crawler belt can destroy cement pavement or asphalt surface, so when needs shift crawler belt machinery, normally crawler belt machinery is placed on the deep loading vehicle and shifts.Crawler belt of the present utility model is to make with rubber, can not destroy the road surface in the time of can walking on highway, with the transfer requirement of convenient machinery.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model schematic perspective view.
Being labeled as in the accompanying drawing: 1-base, 2-strut bar, 3-hydraulic actuating cylinder, 4-crawler belt support, 5-Athey wheel, 6-crawler belt, 7-boss, 8-groove.
The specific embodiment
Be described in further detail of the present utility model below in conjunction with drawings and Examples, but not as the foundation of the utility model being done any restriction.
Embodiment.A kind of crawler belt span control apparatus as depicted in figs. 1 and 2, a kind of crawler belt span control apparatus, the formation of this device comprises base 1, base 1 is to support operator's compartment.During concrete enforcement, the width of operator's compartment can not surpass the minimum span of crawler belt.Base 1 bilateral symmetry is provided with track assembly, track assembly is provided with crawler belt support 4, crawler belt support 4 is main support bodies of track assembly, crawler belt support 4 is provided with at least two Athey wheels 5, to support crawler belt 6, Athey wheel 5 is in transmission connection with crawler belt 6, make crawler belt 6 can be under the driving of Athey wheel 5 scroll forward and backward.Crawler belt 6 usefulness rubber are made, and do not destroy the road surface in the time of can walking on highway, with the transfer requirement of convenient machinery.The bottom of base 1 is provided with boss 7, and the crawler belt support 4 on the track assembly is hinged with the boss 7 of base 1 below through strut bar 2, and the purpose that boss 7 is set is to may be collapsed to base 1 below for crawler belt.Boss 7 both sides are hinged with pair of support rods 2 respectively.Like this when regulating span, can be more steady.Between track assembly and base 1, be provided with hydraulic actuating cylinder 3.Crawler belt support 4 is hinged with the piston rod of hydraulic actuating cylinder 3, and the cylinder body of hydraulic actuating cylinder 3 and base 1 are hinged.Strut bar 2 and hydraulic actuating cylinder 3 are hinged on the boss 7.Boss 7 both sides are provided with groove 8, and the purpose that groove 8 is set is for hydraulic actuating cylinder 3 hydraulic actuating cylinder 3 when shrinking can not blocked by boss 7, makes the folding and unfolding of hydraulic actuating cylinder 3 more flexible.
