Abstract
The utility model relates to creeper treads of a crawler crane. The creeper tread of the crawler crane comprises a bottom plate, side plates, upper cover plates, a bearing plate, a drive bump and coupling sleeves. The side plates are arranged at both sides of the bottom plate, the bearing plate is arranged in the middle of the bottom plate, and a drive bump meshed with the drive wheel is arranged in the middle of the bearing plate. The upper cover plates are at both sides of the bearing plate and fixed with the side plates, coupling sleeves for coupling the two creeper treads are arranged at both sides of the bottom plate. The creeper tread has a cavity in the middle which is provided with reinforcing ribs. The reinforcing ribs at both sides of the creeper tread are distributed in a cross shape and the reinforcing ribs in the cavity in the middle of the creeper tread is connected between the front and rear side plates. The upper cover plate is lower than the bearing plate and the side plate is provided with a bolt mounting boss. With adoption of reasonable reinforcing ribs distributed, the overall weight of the creeper treads of a crawler crane is reduced and the creeper tread can bear greater weight; the upper cover plate is lower than the bearing plate so as to treat the bearing plate thermally conveniently; the bolt mounting boss is provided with bolts so as to prevent the pin from escaping.
Description
Technical field
The utility model belongs to the crawler crane field, relates to a kind of caterpillar block of crawler crane specifically.
Background technology
Used caterpillar block is a cast structure in the machineries such as domestic and international existing crawler-type traveling hoisting crane.Because the caterpillar block size is bigger, and for saving in material, hollow form is made in inside.Caterpillar block is not only born the weight of whole main frame, but also will bear the weight of the thing of slinging, often design pressure-bearing post below caterpillar block pressure-bearing position.Can significantly improve the load-carrying capacity of caterpillar block like this.Weight also needs to move but crawler crane is sling, because the total weight of the main frame and the thing of slinging is very big, running motor is very big to the pulling force of caterpillar block, even can reach 85% of total weight.Because the effect of pressure-bearing post is arranged, and pressure-bearing does not have problem.Before and after have only between the side plate upper and lower plates to connect, do not have other reinforced rib to be connected because huge tension between the caterpillar block, caterpillar block usually appears by drawing crack or situation about breaking.Drawing crack or the position of breaking mainly concentrate on around the adapter sleeve and the re-entrant portion between the side plate of front and back.And, causing foundry technique and Technology for Heating Processing all can be adversely affected because product design is unreasonable, the finished product defective of producing is more, so the structure of product is most important.
Summary of the invention
The purpose of this utility model provides a kind of caterpillar block of crawler crane, rational in infrastructure, easily manufactured, easy to use, dependable performance.
The purpose of this utility model realizes as follows: the caterpillar block of crawler crane, comprise base plate, side plate, upper cover plate, bearing plate, drive blocks, coupling sleeve, side plate is arranged at the base plate both sides, the middle part is a bearing plate above the base plate, the middle part of bearing plate is useful on and drive wheel engagement drive blocks, upper cover plate is in the bearing plate both sides and fixes with side plate, the base plate both sides are provided for the coupling sleeve that connects between two caterpillar blocks, there is cavity at the caterpillar block middle part, in this cavity, reinforced rib is set, the reinforced rib at caterpillar block two ends is crossing distribution, improves the resistance to bending of caterpillar block; Between the side plate on two sides, improve the ability that caterpillar block bears pulling force before and after the reinforced rib of cavities is connected in the caterpillar block.There is cavity at the caterpillar block middle part, with saving in material, and cost-cutting.Base plate and ground-surface effective area of contact are big, reduce the grounding pressure of crawler crane, and the rational reinforced rib that distributes improves overall construction intensity.The surrounded surface of drive blocks also improves wear resisting property through Quenching Treatment.Coupling sleeve is evenly distributed, and prevents the situation that single coupling sleeve bears pulling force.The coupling sleeve of two caterpillar blocks in front and back cooperatively interacts, and the gap is even, the over worn situation of coupling sleeve can not occur.
Upper cover plate is lower than bearing plate, makes bearing plate be easy to heat treatment and raising roughness.Wear resisting property is improved through Quenching Treatment in the surface of the caterpillar wheel joint of bearing plate and crawler crane.
The bolt installation base is set on the side plate.On the bolt installation base, install bolt, prevent that pin from scurrying out.
The utility model distributes by rational reinforced rib, makes overall weight alleviate, and caterpillar block can bear bigger weight; Upper cover plate is lower than bearing plate, makes things convenient for bearing plate heat treatment; Bolt installation base device bolt prevents that pin from scurrying out.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises base plate 1, side plate 3, upper cover plate 4, bearing plate 5, drive blocks 6, coupling sleeve 7, side plate 3 is arranged at base plate 1 both sides, the middle part is a bearing plate 5 above the base plate 1, the middle part of bearing plate 5 is useful on and drive wheel ingear drive blocks 6, upper cover plate 4 is in bearing plate 5 both sides and fixing with side plate 3, base plate 1 both sides are provided for the coupling sleeve 7 that connects between two caterpillar blocks, there is cavity at the caterpillar block middle part, reinforced rib 2 is set in this cavity, the reinforced rib 2 at caterpillar block two ends is crossing distribution, the reinforced rib 2 of cavities is connected between the side plate 3 on two sides, front and back in the caterpillar block, upper cover plate 4 is lower than bearing plate 5, and bolt installation base 8 is set on the side plate 3.The utility model is by drive blocks 6 and drive wheel engagement, adding bearing pin again by coupling sleeve 7 between the adjacent caterpillar block realizes connecting, bolt installation base 8 fitting-up bolt nuts, be used for alignment pin, prevent that bearing pin from scurrying outward, whole caterpillar block contacts with ground by base plate 1, and 5 of bearing plates bear the whole pressure that comes from the caterpillar wheel top.
