Abstract

The utility model discloses a rod piece connector for a boom of a tower crane. The rod piece connector, which is relatively low in cost, comprises a connector body; a connecting pin shaft hole and a jacklift traveling surface are arranged on the connector body; the connector body is a casting part; the jacklift traveling surface is a machining surface with machining allowance, and other outer surfaces of a jacklift are casting modeling surfaces; the connecting pin shaft hole is a machining hole; the connector body is a fork head or a fork holder. The rod piece connector has the benefits that the manufacturing cost of the rod piece connector is reduced greatly, the production efficiency is improved, and the rod piece connector is mainly applicable to booms of tower cranes.

Description

Tower Crane Boom ' rod member joint

Technical field

The utility model relates to a kind of Tower Crane Boom ', especially a kind of rod member joint being used on jib rod member.

Background technology

At present, domestic Tower Crane Boom ' rod member coupling hook used, forked standard are forging, machine up after forging molding and obtaining, its machining amount is large, waste of raw materials is large, and the process-cycle is long, and production efficiency is low, productive costs is high, does not meet the development tendency of resource-conserving and environment-friendly society.

Utility model content

In order to overcome the higher deficiency of existing forging joint cost, technical problem to be solved in the utility model is to provide the Tower Crane Boom ' rod member joint that a kind of cost is lower.

The utility model solves the technical scheme that its technical matters adopts: Tower Crane Boom ' rod member joint, comprise joint body, on joint body, be provided with connecting pin axis hole and crane carriage walking surface, described joint body is Casting Parts, described crane carriage walking surface is the machinework face that is designed with stock left for machining, and all the other outside faces are for being cast as profile; Described connecting pin axis hole is machined holes.

Described joint body is jaw.

Described joint body is forked standard.

The beneficial effects of the utility model are: greatly saved the cost of manufacture of rod member joint, improved production efficiency, be mainly used in Tower Crane Boom '.

In figure, be labeled as, 1-connecting pin axis hole, 2-crane carriage walking surface, 10-jaw, 11-forked standard, 20-forges jaw, and 21-forges forked standard.

In each figure, fill area represents stock allowance.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, existing for Tower Crane Boom ' jaw, forked standard all adopt Forging Parts, its stock left for machining is large, waste material is serious, thereby cost is higher.

As Fig. 5, Fig. 6, Fig. 7, shown in Fig. 8, Tower Crane Boom ' jaw of the present utility model, forked standard all adopts Casting Parts, except crane carriage walking surface 2 is for to be designed with the machinework face of stock left for machining, all the other outside faces are and are cast as profile, described connecting pin axis hole 1 is machined holes, can guarantee that working accuracy meets matching requirements, and the carriage walking rail level integral body forming after assembling is comparatively smooth-going, without significantly step and fluctuating, guarantee that crane carriage operates steadily, due to without other special requirement, existing precision casting technology meets the processing request on bulk strength and described remainder surface completely, thereby direct casting, in the time of must not making joint as employing Forging Parts again, carry out machinework, part materials amount and overhours have greatly been saved, in addition, during assembling, according to crane carriage walking surface 2, can identify more quickly the assembly direction of part, saved time of setting up, therefore cost is lower.
