Abstract

The utility model discloses a high strain pile testing weight release device, which comprises a release handle, a combined lifting ring, a central pin roll and a release handlebar. The release handle is a long ring plate with a notch at the bottom. A connecting hole is arranged in the top of the release handle. By taking a connecting line between the center of the notch and the center of the connecting hole at the top as a boundary line, the release handle is divided into a left release handle and a right release handle. The top of the release handle is connected with the combined lifting ring through the central pin roll. The release handle and the combined lifting ring can relatively rotate around the central pin roll. The high strain pile testing weight release device provided by the utility model has the beneficial effects that the structure is simple, the cost is low, the release device is simple to operate and convenient to use, the working efficiency is high, the release device can be reused, the cost is saved, and the safety and the reliability of high strain pile testing are improved.

Description

High Strain Method foundation pile detects the weight detacher

Technical field

The utility model relates to a kind of high Strain Method foundation pile and detects the weight detacher, belongs to field of mechanical technique.

Background technology

In the acceptance checking of pile foundation process process, adopt high Strain Method that bearing capacity of single pile and integrality are detected test, test is finished on the conventional free-falling hammer Driven Piles top of adopting.Conventional method adopts crane boom to sling and reaches tens tons of weights for being to build gantry, improves certain altitude, allows its Driven Piles that drops hammer push up, and not only wastes time and energy, and efficient is low, and the increase expense.

The utility model content

The utility model provides a kind of high Strain Method foundation pile to detect the weight detacher, adopts Steel material through designing, process, being made, and available crane lifts by crane at any time, dropping hammer to reach tens tons of weights, and Hoisting Security is simple to the king-pile position, break off relations flexibly, image data is stable, and effect is high, expense is low.

For solving above technical problem, the utility model provides following technical scheme: a kind of high Strain Method foundation pile detects the weight detacher, and described detacher comprises unhook handle, combination suspension ring, central pin shaft and unhook handle; Described unhook handle is the oval annular slab that the bottom has gap, and unhook handle top has connecting hole, and take the center of gap and top connecting hole as the line of demarcation, the unhook handle is divided into left unhook handle and right unhook handle; The combination suspension ring comprise the suspension ring bar of two blocks of parallel plates and vertical flexible connection two parallel-plates, and two parallel-plates can rotate around the suspension ring bar; The unhook handle is located between two blocks of parallel-plates of combination suspension ring, and adopts central pin shaft to be flexibly connected; Be fixed with two axles on the described unhook handle, be arm pivot post and unhook axle, arm pivot post and unhook axle are individually fixed in left unhook handle and right unhook handle; Described unhook handle is F shape, and its middle beam is used for the connecting handle rotating shaft, forms lever with arm pivot post, forms the turning between end crossbeam and the longeron and becomes draw-in groove, is stuck on the unhook axle.

Further, described unhook handle is similar to the both sides, front and back that clip structure is connected in the unhook handle, and corresponding arm pivot post and the unhook axle that is used for connecting also has respectively two, is symmetrically distributed in the front and rear panel face of unhook handle.

Further, be provided with the unhook elbow between described unhook handle and combination suspension ring, the unhook elbow is arc.

This high Strain Method foundation pile that the utility model relates to detects the weight detacher, and weight is in mentioning process, and the draw-in groove of unhook handle is stuck on the unhook axle, can left and right unhook handle is fastening, dwindle the gap size; When needs break away from, only need manual unhook handle, draw-in groove is broken away from the unhook axle, can realize the smooth disengaging of weight.This free unhooking device of counter weights for single-pile tests, rational in infrastructure, safe and reliable, experimental data is accurate, having guaranteed at the trial iron hammer lifting and dropped hammer all can be effectively controlled, has promoted the safety of test, flexibility, operability, and this device can be reused, and has saved cost of production.

Description of drawings

Fig. 1 is that the high Strain Method foundation pile of the utility model detects weight detacher elevation;

Fig. 2 is that the high Strain Method foundation pile of the utility model detects weight detacher lateral view;

Mark among the figure is as follows: 1. left unhook handle; 2. right unhook handle; 3. right unhook elbow; 4. combination suspension ring; 41. suspension ring bar; 6. central pin shaft; 7. unhook handle; 8. arm pivot post; 9-unhook axle; The 10-gap.

The specific embodiment

Shown in Fig. 1-2, detacher comprises unhook handle, combination suspension ring 4, central pin shaft 6 and unhook handle 7; The unhook handle is the oval annular slab that the bottom centre place has gap 10; The unhook handle be divided into symmetrical left unhook handle 1 and right unhook handle 2, about long and narrow groove between the unhook plate be used for connecting weight, gap 10 is used for making weight to break off relations; Unhook handle and 4 on suspension ring of combination are provided with unhook elbow 3, and unhook elbow 3 is arc, and as shown in Figure 1, two unhook elbows all are located at the right side of unhook handle; Combination suspension ring 4 comprise the suspension ring bar 41 of two boards and vertical flexible connection two boards; Be fixed with two axles on the left unhook handle 1 of unhook handle and the right unhook handle 2, be respectively arm pivot post 8 and unhook axle 9.

As shown in Figure 1, only need rotation unhook handle 7, can easily realize the smooth unhook of weight.

This high Strain Method foundation pile that the utility model provides detects the weight detacher, and is simple in structure, with low cost, simple to operate, easy to use, high efficiency, and can reuse, save cost, have the beneficial effect of the safety and reliability that improves the foundation pile high stress detection.

The specific embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
