Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of this utility model protection.
As it is shown in figure 1, this utility model is applicable to a kind of embodiment of the pull bar device for measuring force of avalanche monitoring.The pull bar device for measuring force being applicable to avalanche monitoring of the present embodiment includes: first steel bar rod the 1, second steel bar rod 2, connect the first steel bar rod 1 and the reinforcing rib meter 3 of the second steel bar rod 2 and the spring 4 being connected with the second steel bar rod 2 away from one end of reinforcing rib meter 3.In other words, the first steel bar rod 1, reinforcing rib meter the 3, second steel bar rod 2 and spring 4 are sequentially connected with.In the present embodiment, the first steel bar rod 1 and the second steel bar rod 2 two ends with reinforcing rib meter 3 respectively are welded.Reinforcing rib meter 3 is vibrating string type sensor, for detecting the stress of connected steel bar rod.Reinforcing rib meter 3 is connected with readout instrument 5, and the frequency values shown by readout instrument 5 can calculate corresponding stress, strain.
Preferably, in the present embodiment, being also associated with the 3rd steel bar rod 6 at spring 4 away from one end of the second steel bar rod 2, the two ends of spring 4 are respectively welded with the second steel bar rod 2 and the 3rd steel bar rod 6.The pull bar device for measuring force being applicable to avalanche monitoring of the present embodiment also includes protecting sleeve 7, protection sleeve 7 to be coated at spring 4, be used for protecting spring 4 injury-free, extend its service life.
Further, in the present embodiment, spring 4 is not less than the spring of 20kN for holding capacity so that it is can bear the bigger pulling force that it is produced by the large deformation of actual avalanche, ensure that pull bar device for measuring force can normally work, and the requirement of the sufficiently large avalanche Fracture Deformation of monitoring can be met.The external diameter of spring 4 is not more than 10cm, in order to install, ensure attractive in appearance.Preferably, in the present embodiment, the steel wire diameter of spring 4 is 22mm, and the external diameter of spring 4 is 90mm, a length of 20cm, and its maximum holding capacity is 31kN.Certainly, the size of spring is not limited to the present embodiment, but can be according to actually detected environmental selection.
The present embodiment above-mentioned is applicable to the pull bar device for measuring force of avalanche monitoring in use, is placed between the crack of collapse body 8, will the first steel bar rod 1 and the 3rd steel bar rod 6 is fixing with the both sides in crack respectively is connected.When collapse body 8 is moved, first steel bar rod the 1, second steel bar rod 2, spring 4 and the 3rd steel bar rod 6 will be produced pulling force, and make first steel bar rod the 1, second steel bar rod 2, spring 4 and the 3rd steel bar rod 6 produce stretcher strain therewith.Can record its tension stress and strain by reinforcing rib meter 3, owing to spring 4 is connected with reinforcing rib meter 3, therefore pulling force suffered by spring 4 is equal with the tension that reinforcing rib meter 3 records, and thus can converse the strain of spring 4, thus obtain total dependent variable.I.e., the frequency values that the pull bar device for measuring force being applicable to avalanche monitoring of the present embodiment is read by the readout instrument 5 being connected with reinforcing rib meter 3 just can obtain the tension suffered by steel bar rod and spring 4 and total deflection, thus can get collapse body 8 and start to be deformed to change and the displacement of avalanche deformation generation of the power of avalanche generation all stage, and then the relation curve of pulling force and deformation can be obtained.If being monitored for a long time in engineering, it is possible to obtain the relation curve of deformation and time, thus according to its variation tendency, collapse hazard is predicted and early warning.
To sum up, the above-mentioned pull bar device for measuring force being applicable to avalanche monitoring of the present embodiment measures real-time pulling force when available collapse body 8 deforms and deformation data by reinforcing rib meter 3, effectively the deformation process of collapse body 8 is monitored, and according to its variation tendency, collapse hazard is predicted and early warning.Owing to being additionally arranged spring 4, thus add its deflection that can bear, therefore, it is possible to meet the monitoring of avalanche large deformation.This pull bar being applicable to avalanche monitoring surveys that apparatus structure is simple, low cost, measurement precise and high efficiency, suitable for large-scale promotion, and is particularly suited for the monitoring of collapse body generation large deformation.
