Abstract
The utility model discloses a tensioning device of a hydraulic band track device. The tensioning device of the hydraulic band track device comprises a top plate, wherein the front end of the top plate is connected with a shaft of a driven wheel, and the back end of the top plate is connected with a hydraulic oil cylinder which is fixed on a band track frame and is driven by a hydraulic system. The hydraulic system is adopted by the tensioning device of the hydraulic band track device, and the driven wheel achieves tensioning and loosening of a band track under the stretching and contracting action of the hydraulic oil cylinder. The tensioning device of the hydraulic band track device has the advantages that the stability is high, the phenomenon of loosening is avoided, and the tensioning device of the hydraulic band track device also can be used with high loading capacity or in bad working conditions, so the range of application is wide; the hydraulic system is adopted for transmission, so the tensity can be controlled effectively, the tensity of the band track is enabled to be adjustable and the walking is stable and safe, so requirements of different working conditions are met; in maintenance, compared with a spring mechanism, the tensioning device of the hydraulic band track device is convenient and fast to disassemble and assemble, time and labor are saved, and the labor intensity is relieved.
Description
One, technical field
The utility model belongs to the crawler attachment corollary apparatus, is specifically related to a kind of hydraulic track device stretching device.
Two, background technology
The develop rapidly of domestic crawler crane and the development of relevant industries are so that people to the requirement of crawler crane further.Crawler attachment is the important composition of crawler crane, generally includes the traveling gear, track frame and the crawler belt that are made of principal and subordinate wheel, and wherein flower wheel is realized sliding block joint by slide block and track frame.After this device uses a period of time, because the wearing and tearing of rail chain pin sleeve cause pitch to increase, make under the whole crawler belt heavyly, cause the track frame that weares and teares, derail and fall chain etc., have a strong impact on walking performance and service life, therefore need to adjust crawler belt, make crawler belt keep certain degree of tension.To achieve these goals, usually adopt track tension device.At present track tension device commonly used comprises the top board that front end is connected with the axle of flower wheel, and this top board rear end is connected with spring device on being fixed on track frame.Utilize the elastic force promotion flower wheel of recoil spring to hold out against crawler belt, thereby realized the tension to crawler belt.There is following deficiency in this kind tensioned mode: 1, less stable, high capacity or bad working environments etc. to the higher situation of the requirement of strength of recoil spring under, spring very easily relaxes, and causes the tensioning ability to descend, and is difficult to meet the demands; 2, degree of tension can't be controlled effectively, and is difficult to satisfy the demand of different operating modes; When 3, safeguarding, spring device dismounting difficulty wastes time and energy, and labour intensity is large.
Three, summary of the invention
It is high that the purpose of this utility model provides a kind of stability, and degree of tension can be controlled, hydraulic track device stretching device convenient to disassembly.
For achieving the above object, the technical solution adopted in the utility model is: this mechanism comprises front end and the top board that the axle of flower wheel is connected, and is characterized in: the rear end of top board be fixed on track frame on, be connected by the hydraulic ram of hydraulic efficiency pressure system transmission.
The utility model adopts the hydraulic efficiency pressure system transmission, and the telescopic action by hydraulic ram is realized the tensioning of crawler belt and loosened in flower wheel.Have following advantage: 1, stability is high, relaxation can not occur, all also can use in high capacity or bad working environments, and Applicable scope is extensive; 2, adopt the hydraulic efficiency pressure system transmission, degree of tension can be controlled effectively, and makes the degree of tension of crawler belt have adjustability, so that the more steady safety of walking, has also satisfied the demand of different operating modes; When 3, safeguarding, convenient to disassembly than spring device, time saving and energy saving, reduced labour intensity.
Four, description of drawings
Fig. 1 is structural representation of the present utility model.
Five, the specific embodiment
As shown in the figure, the utility model comprises the top board 4 that front end is connected with flower wheel 3 axles.Flower wheel 3 is realized sliding block joint by slide block and crawler rack 5.The rear end of top board 4 be fixed on track frame 5 on, be connected by the hydraulic ram 1 of hydraulic efficiency pressure system transmission.Among the figure 2 is caterpillar wheel.
Claims (1)
1. a hydraulic track device stretching device comprises front end and the top board (4) that the axle of flower wheel (3) is connected, and it is characterized in that: the rear end of top board (4) be fixed on track frame (5) upper, be connected by the hydraulic ram (1) of hydraulic efficiency pressure system transmission.
