Description
Technical field
The utility model relates to construction engineering test technical field, particularly relates to a kind of pile foundation high strain monitoring well formula leading truck.
Background technology
High strain monitoring is a kind of main method of pile detection, and whether and the height of the distance that falls the bias that the accuracy of high strain dynamic testing depends on weight to a great extent.Usually adopt crane weight to be lifted to a certain height in prior art then freely to fall by manually knocking release weight, in order to ensure that weight is aimed at foundation pile and needed the at substantial time to adjust in process of the test, and the accuracy of alignment of weight and foundation pile is difficult to ensure, also there is the easy landing of weight and cause damage equivalent risk to personnel and instrument, and when weight abrupt release, larger impact force is caused to jack lift, easily damage crane.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provide a kind of test efficiency high, test accurate, safe and reliable pile foundation high strain monitoring well formula leading truck.
The utility model for the technical scheme reaching above-mentioned technical purpose and adopt is: a kind of pile foundation high strain monitoring well formula leading truck, comprise a leading truck main body, the framework of groined type is provided with in described leading truck main body, the bottom of described leading truck main body is provided with hollow support base, the top of described leading truck main body is provided with the guide wheel wearing guiding steel wire rope, the upper end of described wire rope is provided with the joint be connected with hoist lifting hook, the lower end of described wire rope connects one to weighing scoop shape clamp, described to being provided with moving jaw and the spoon arc that can drive moving jaw folding in weighing scoop shape clamp, described moving jaw in weighing scoop shape clamp to be flexibly connected with the hangers on weight, be provided with in described leading truck main body can knock described spoon arc open moving jaw knock block, during high strain monitoring test, first weight handling is placed on Under Pile top, and make center and the stake top center superposition of weight, then crane is utilized to sling leading truck main body, make the hollow support base of leading truck bottom part body through weight and foundation pile, be firmly placed on around test pile on ground, by the hangers on the moving jaw fastening weight in weighing scoop shape clamp, hoist lifting hook is connected with the joint of the upper end of wire rope, utilizes crane that weight is promoted lifting, arrange the center of weight when guide wheel can ensure to sling weight in lifting leading truck main body to keep overlapping with stake end face center, when in weighing scoop shape clamp spoon arc lifting certain altitude encounter knock block time, moving jaw in weighing scoop shape clamp is opened and departs from the hangers on weight, weight free-falling impact stake top, the detecting sensor being arranged on pile body both sides carries out strain detecting.
The described block that knocks is located on an adjustment mount pad, and be provided with height cuing scale in described adjustment mount pad, described adjustment mount pad is located in described leading truck main body again; The setting height(from bottom) of knocking block can be adjusted easily, the distance thus adjustment effective control weight falls according to test requirements document.
The bottom of described leading truck main body is provided with enhancing structure with oblique member, and described enhancing structure with oblique member is provided with step.
The beneficial effects of the utility model are: after adopting said structure, by arranging a well formula leading truck, well formula leading truck arranges can the wire rope guide wheel that leads of weight, eccentric when effectively can prevent tension weight churning stake top, and well formula leading truck arrange effectively can control that weight falls distance knock block, ensure that in process of the test, the stressed specification of foundation pile is reliable, testing inspection data accurate stable; Well formula leading truck can also prevent from pushing up landing from stake during tension weight churning stake top, eliminates the risk that weight landing causes injury to personnel and instrument damage, is conducive to improving the safety detected, can also reduces the impact force to jack lift, is conducive to protecting jack lift.
