Description
Technical field
Engineering detecting field is the utility model is related to, is dropped hammer ranging computer more particularly, to a kind of Large strain.
Background technology
According to DGJ08-218-2003《Architecture foundation pile detection technique code》In regulation, tackle high strain monitoring in falling
Hammer distance is measured.
Existing detection method be mostly by artificial close to the weight elevated, using Sopwith staff or steel tape dropped hammer away from
From measure, there is larger potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of Large strain and dropped hammer ranging computer, and it, which is avoided, puts testing staff
Dangerous situation under weight, substantially increases security.
Dropped hammer range determination in order to solve the above technical problems, embodiment of the present utility model provides a kind of Large strain
Instrument, it includes：Base (1), it is provided with wire coil component (5), and wire coil component is provided with swinging handle (4)；It is installed on base
Expansion link (8), its leading section are provided with pulley (9)；Be wound in the tape measure (7) of wire coil component, its leading section by after pulley from
By hanging down, the leading section of the tape measure is provided with the sensor (10) that position signalling is sent when tape measure front end drops down onto stake top, sensing
Device is wirelessly or wired mode is connected to the device of warning (6) at wire coil component.
Compared with prior art, Large strain provided by the utility model drop hammer ranging computer can ensure measurement accuracy
On the premise of, testing staff is avoided too close to weight, so as to produce unnecessary danger.
Further, wire coil component is provided with carrying handle (3).
Further, wire coil component (5) is arranged above base (1) by mounting seat (2).
Further, device of warning is buzzer or warning light.
Further, wire coil component, which is provided with when tape measure front end drops down onto stake top, enters line-locked locking dress to wire coil component
Put, the locking device is connected to controller, and the controller is connected with sensor.
Brief description of the drawings
Fig. 1 is that Large strain drops hammer ranging computer side view；
Fig. 2 is that Large strain drops hammer ranging computer center base and drum front elevation.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
In conjunction with specific embodiments, the utility model is expanded on further in face.
As shown in Figure 1 and Figure 2, a kind of Large strain drops hammer ranging computer, and it includes：Base 1, it is provided with wire coil component
5, wire coil component is provided with swinging handle 4, and operating personnel can allow the tape measure of wire coil component gradually to discharge with swinging handle.
The expansion link 8 of base is installed on, the expansion link can cover tubing expansion link or such as cylinder class stretching structure,
This is not limited, and expansion link leading section is provided with pulley 9, the pulley passed through by tape measure after vertically downward.It is wound in drum
The tape measure 7 of component, by freely being hung down after pulley, the leading section of the tape measure is provided with when tape measure front end drops down onto stake top for its leading section
When send the sensor 10 of position signalling, such as position sensor etc., sensor is wirelessly or wired mode connection
Device 6 of warning at wire coil component.
For convenience of the mobile product, wire coil component is provided with carrying handle 3, and the carrying handle is vertically installed on wire coil component
At the mounting seat at place, and wire coil component 5 is arranged at the top of base 1 by mounting seat 2.
It is noted that device of warning is buzzer or warning light, work as in addition, wire coil component sets to set
Enter line-locked locking device when tape measure front end drops down onto stake top to wire coil component, the locking device is connected to controller, the control
Device is connected with sensor, for example, the locking device is locking motor, the rotation axis connection of the locking motor and wire coil component,
Under normal circumstances, locking motor can carry out line laying work with wire coil component, when controller knows that tape measure front end has dropped down onto
The signal of stake top, then controller controls locking motor to lock and then the rotary shaft of wire coil component can not be rotated, so that skin
Chi is no longer released.It is of course also possible to other mechanisms such as brake disc device are set to realize locking effect at rotary shaft.
The application method of the product is：Need drop hammer range measurement when, expansion link is protruding, and pulley contact is high should
Become weight hammer bottom, tape measure is freely hung down by pulley, and tape measure top sets a sensing device, sensing device free-falling to stake top
When, buzzer is triggered, represents that measurement distance now is distance of actually dropping hammer.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
