Technical Field
The utility model relates to a bank bridge installation technical field particularly, relates to a connect otic placode, pull rod and bank bridge.
Background
Various cranes (such as shore bridges) have a statically indeterminate design with double pull rods, which bear certain loads respectively. Because of unavoidable manufacturing tolerances during manufacture and because the structure is statically indeterminate, the tie rods often require a certain amount of adjustment in length to allow the load to be within the design tolerances. In addition, after the crane is in service for a period of time, the pull rod load originally within the design error range gradually begins to be out of tolerance due to the reasons of component abrasion or structural deformation and the like, and further the normal operation and even the safety of the crane are influenced. In this case, the length of the pull rod also needs to be adjusted accordingly.
In order to avoid the overlong slenderness ratio of the pull rod and the requirement of some cranes on pitching working conditions, generally, one pull rod is actually formed by connecting a plurality of connecting rods in series, and every two pull rods are connected by a pin shaft. The adjustment is basically made by extending or shortening the theoretical length of the shortest or easiest to adjust link in the series to bring the load back within the normal range. During specific implementation, a large number of measurements are often required on site, and after the exact numerical value of the required extension or shortening is obtained by matching with theoretical calculation, the pull rod is correspondingly processed and adjusted. It therefore has the following disadvantages:
1 the field workload is large. A large amount of measurement is needed to obtain the height difference of the trolley track of the crane; side bending and down bending data of the steel structure; the exact length of each pull rod, etc. are matched with the design requirements of original drawing paper and theoretical calculation, and then the processing allowance can be obtained.
2, the precision is poor, and even if the corresponding machining allowance is calculated, the expected effect cannot be achieved after the modification is implemented due to field measurement errors or other unpredictable reasons.
3 in order to avoid above-mentioned two problems, often need prefabricated several pull rods, length is different, changes one by one according to actual conditions during site operation until finding the most suitable one. The construction mode is time-consuming, labor-consuming and high in cost.
