Description
Technical field
The present invention relates to construction quality detection technique field, especially a kind of experimental rig for carrying out guardrail horizontal loading.
Background technique
Guardrail is mainly used for protection and protection to personal safety and installations and facilities.Guardrail everywhere may be used in we live
See, the protection for personal safety can be played in being applied to the occasions such as house, shopping centre, public place, and guardrail is even more road
Epochmaking facility in facility, guardrail experience the safety that road edge is gone along with sb. to guard him in addition to that can provide driver, in side slope or
Under the roads such as hill path, if having traffic accident generation, there is guardrail that vehicle can be protected directly not rush outward and fall, to avoid causing more
On the very high road of such average speed of heavy casualties, especially highway or through street, the intensity of Guardrail design is more formal
Can close certainly generate the effect for stopping vehicle when traffic accident occurs.So producer needs after guardrail is produced
The various performances of guardrail are tested, to guarantee the intensity of guardrail.In People's Republic of China's building industry professional standard
There is the standard to guardrail wires, at present includes the test of following two for the test of intensity: 1, resisting soft weight body to resist performance；
2, anti-hard weight body resists performance.But due to currently on the market without it is special for detect it is above-mentioned resist soft weight body resist and
The equipment for resisting hard weight to resist, it is often necessary to which testing staff to going selective examination detection on the spot, and due to the limitation in place, in guardrail
It is not nearby the wall that all there is science and technology and hang soft weight, so causing difficulty, and the mode of above-mentioned shock to test
It is not only dangerous, and testing result is also inaccurate.
106989881 A of Chinese invention patent application CN discloses a kind of guardrail shock detection device, including first
Frame, first support include two the first bottom plate, more first struts being vertically arranged on the first bottom plate, connection first struts
First crossbar；The second support includes the second bottom plate, more second struts being vertically arranged on the second bottom plate, connection two
The second crossbar of second strut is provided at least one in first crossbar for hit that weight hangs and hangs part, in second crossbar
On be provided with and pull part, described to pull part and be connected by engaging portion with weight is hit, having reached above-mentioned two bracket can rise
Two transporting brackets to scene are carried out weight by can be achieved with after simply installing by the detection device mobile to one
The experiment that object is hit.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of opposition can be provided to guardrail load experiment
Experimental provision.
In order to solve the above technical problems, a kind of experimental rig of carry out guardrail horizontal loading of the invention, including bracket, institute
State that bracket is in the shape of a right-angled ladder, the right angle of the bracket is provided with rolling pulley group；Further include be arranged in it is electronic in bracket
Pump and electronic dynamometer, the electronic dynamometer are fixed on guardrail top position to be measured, and the electronic dynamometer passes through wirerope
It is connected with electrodynamic pump, the wirerope bypasses rolling pulley group；By the guardrail to be measured and electronic dynamometer same level position
The place of setting is fixed with electron displacement detection meter, and the electron displacement detection meter, electronic dynamometer are connected with controller input terminal, institute
Controller output end is stated to be connected with electrodynamic pump and alarm.
Further, the rolling pulley group includes the first rolling pulley, the second rolling pulley and third rolling pulley, institute
It states the first rolling pulley and the second rolling pulley vertical direction is disposed side by side on the first right angle of bracket, the third, which rolls, to be slided
Wheel is arranged in the second right angle.
After above-mentioned apparatus, the present invention can to guardrail load experiment provide opposition, the configuration of the present invention is simple,
Convenient and practical, load is accurate, and equipped with displacement alarm.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a kind of structural schematic diagram for the experimental rig for carrying out guardrail horizontal loading of the present invention.
In figure: 1 is bracket, and 3 be wirerope, and 4 be electrodynamic pump, and 5 be electron displacement detection meter, and 6 be electronic dynamometer, and 7 are
Controller, 8 be guardrail to be measured
201 be the first rolling pulley, and 202 be the second rolling pulley, and 203 be third rolling pulley.
Specific embodiment
As shown in Figure 1, a kind of experimental rig of carry out guardrail horizontal loading of the invention, including bracket 1, the bracket 1
In the shape of a right-angled ladder, the right angle of the bracket 1 is provided with rolling pulley group；It further include 4 He of electrodynamic pump being arranged in bracket
Electronic dynamometer 6, the electronic dynamometer 6 are fixed on 8 top position of guardrail to be measured, and the electronic dynamometer 6 passes through wirerope 3
It is connected with electrodynamic pump 4, the wirerope 3 bypasses rolling pulley group；8 side of guardrail to be measured and the same water of electronic dynamometer 6
The prosposition place of setting is fixed with electron displacement detection meter 5, the electron displacement detection meter 5, electronic dynamometer 6 and 7 input terminal of controller
It is connected, 7 output end of controller is connected with electrodynamic pump 4 and alarm.
Further, the rolling pulley group includes that the first rolling pulley 201, the second rolling pulley 202 and third roll
Pulley 203, first rolling pulley 201 and 202 vertical direction of the second rolling pulley are disposed side by side on the first right angle of bracket 1
Place, the third rolling pulley 203 are arranged in the second right angle.
Working principle of the present invention is as follows: in the case where position of 8 surrounding of guardrail to be measured without opposition, by bracket
1 effect is placed across guardrail 8 to be measured, electronic dynamometer 6 is fixed on 8 top position of guardrail to be measured, starting electrodynamic pump 4 is added
It carries, after the reading of electronic dynamometer 6 reaches horizontal loading requirement, when record displacement, such as displacement are more than that preset standard requires, electronics
Displacement detecting meter will be issued and be alarmed.
The device can be used for testing agency, residential quarters, arenas, large scale business body, school, hospital, lakeside and public area
The periphery of guardrail can be used in the case where can not finding the position that can provide opposition to horizontal loading test in domain, should
Apparatus structure is simple, convenient and practical, and load is accurate, and equipped with displacement alarm.
Although specific embodiments of the present invention have been described above, those skilled in the art should be appreciated that this
It is merely illustrative of, various changes or modifications can be made to present embodiment, without departing from the principle and substance of the present invention,
