Abstract
The utility model discloses a guiding wheel device capable of tensioning crawler belt, which comprises a guiding wheel mounted on a support, and a grease cylinder with the base connected on a base; the piston rod of the grease cylinder is inserted into the spring cavity on the rear end of the support; a compressed spring is sleeved on the piston rod with the front end supported on the inter-wall of the support and the rear end supported on the shaft shoulder of the piston rod. In the utility model, the piston rod in the grease cylinder pushes the support and the guide wheel to move by the spring to tension the crawler belt. The device achieves the advantages of simple structure, low cost and high operation reliability.
Description
Technical field
The utility model relates to a kind of development machine that is used for mining, is specifically related to a kind of securable guide wheel device of development machine traveling crawler.
Background technology
The development machine traveling crawler because the connection bearing pin between the caterpillar block produces plastic deformation and pin shaft hole wearing and tearing, can make the crawler belt length overall elongated, the phenomenon that causes development machine to produce chain jamming in the process of walking, take off chain in the long-term use process.In order to solve this technical problem, patent documentation CN201287772Y discloses a kind of tension structure and traveling crawler of traveling crawler, this tension structure comprises tensioning hydro-cylinder, piston rod, bracing frame, bogie frame adapter plate, wherein said tensioning hydro-cylinder has cylinder body, has piston in the described cylinder body, the contact position of described piston and described cylinder body has packing element, and described piston is divided into two parts with described cylinder body; Described piston links to each other with piston rod one end, and any one in described piston rod and the described cylinder body is connected by articulated structure with described bogie frame adapter plate, and another is captiveed joint with support frame as described above.But this technical scheme remains in complex structure, deficiency that cost is high.
Summary of the invention
The utility model aims to provide the securable guide wheel device of a kind of crawler belt simple in structure, that productive costs is low, functional reliability is high.
In order to achieve the above object, the technical solution adopted in the utility model is: the securable guide wheel device of crawler belt, comprise rack-mount guide wheel, and base is connected the butter cylinder on the support, the piston rod of butter cylinder stretches in the spring cavity of back-end support, compression spring is sleeved on the piston rod, and front end props up the support partition, and the rear end props up the shaft shoulder of piston rod.
When butter cylinder pressurization oiling, piston rod is extrapolated, and the shaft shoulder is to the rear end of the compression spring application of force, and the front end by compression spring promotes support and guide wheel moves forward, with tensioned tracks.
Above-mentioned piston rod is nested in the partition axis hole, and butter cylinder cylinder body is nested in the rear wall axis hole.Piston rod and butter cylinder cylinder body all are nested in the axis hole, and relative fixed stable nothing in position is rocked during work, make the sealing member between piston rod and the butter cylinder be difficult for loss, functional reliability height, long working life.
Above-mentioned guide wheel is installed in the support termination by end plate.Can dismantle guide wheel by the dismounting end plate, make installation and maintenance more convenient.
The piston rod of butter cylinder promotes support by compression spring and guide wheel moves in the utility model, to reach the purpose of tensioned tracks, has simple in structurely, and cost is low, and the serviceability advantages of higher.
