Description
Technical field:
The utility model relates to a kind of transportation means, especially a kind of crawler belt that moves the vehicle of load-carrying on the ladder road.
Background technology:
Chinese patent ZL98208907.4 once disclosed a kind of automobile-used crawler belt, was connected with the cross-tie base on its every joint strap frame, and frame is connected as a single entity with the support base.Though this crawler belt can move on the ladder road, easy damaged step when vehicle load is big, and because the crawler belt acting point is fixing, the shoe wheel is rotated be obstructed, the step difficulty of climbing, influence transportation result of use.
Summary of the invention:
The utility model aims to provide and a kind ofly can make Athey wheel steady running work, and the step that climbs does not damage the cart for travelling up or down stairs crawler belt of step smoothly again.
Task of the present utility model is finished like this, a kind of cart for travelling up or down stairs crawler belt, it includes is with joint, adapter shaft, axle sleeve to roll, it is characterized in that: each band joint is grabbed tooth by connecting strap and plastic cement and is formed, connecting strap and plastic cement are grabbed tooth for being solidly connected, the band joint is close to the band joint and is connected, and it is rectangle that plastic cement is grabbed tooth denticle cross-sectional plane, and the end is a △ shape crown.
The utility model closely is difficult for K/UP because the band joint has bigger thickness and arranges, and Athey wheel is worked well, and the step of creeping is smooth and easy, and plastic colloid is grabbed not easy damaged step of tooth.
Description of drawings:
Fig. 1 is a Facad structure scheme drawing of the present utility model.Fig. 2 is the construction profile scheme drawing of the utility model band joint.Among the figure: 1. band joint 2. adapter shafts 3. axle sleeves roll 4. connecting straps 5. and grab tooth 6. denticles 7. crowns.
The specific embodiment:
Band joint 1 is grabbed tooth 5 by connecting strap 4 and is formed, grabbing tooth 5 is made up of denticle 6 and crown 7 again, the cross-sectional plane of denticle 6 is a rectangle, crown 7 is a △ shape, denticle 6 is made with crown 7 usefulness plastic material disjunctors, and grabs tooth 5 and connecting strap 4 for being solidly connected, and is with to save 1 also available engineering plastics integral molded plastic and make, band joint 1 be connected with adapter shaft 2 between band joint 1 is close to mutually, be with axle sleeve outside the adapter shaft 2 and roll 3.After the crawler belt sealing, when the sprocket wheel at two ends load rotated, the crawler belt joint was subjected to ladder road surface upward reaction force in various degree, was close to mutually between band joint and the band joint, can K/UP, and assurance sprocket wheel smooth operation.When running into step, the tooth 5 of grabbing on the band joint 1 is caught step and can be climbed smoothly.
