Abstract
A strength and compression resistance testing device of a bus duct structure comprises a support enabling a bus duct to be placed in the middle, a rigid plate arranged on the upper portion of an outer casing of the bus duct and a pressing device placed on the rigid plate are allocated in the support, a pressure sensor is placed between the pressing device and the support, and an output signal line of the pressure sensor is connected with a pressure measurement device. The support is in a shape of a box, the support is used for keeping relative locations and counter-acting force between the bus duct to be placed and the pressure sensor. The built-in rigid plate is a square block with a hem width equal to that of the bus duct. The strength and compression resistance testing device has the advantages of being simple in structure, reasonable, convenient to operate, strong in application, accurate in data, safe, reliable and the like.
Description
Technical field
The utility model relates to a kind of device that is used in checking bus duct structural strength and compression resistance performance test, belong to pressure, pressure sensing, field of measuring technique.
Background technology
Along with emerging in large numbers of modernization project facility and equipment, the power consumption of all trades and professions is fast to be increased, the appearance in especially numerous skyscrapers and large-sized workshop workshop, and plug type bus duct arises at the historic moment as a kind of novel distribution lead.
Compare with traditional cable; When bus duct is carried at big electric current; Since adopted new technology, new technology, the junction, bus duct both ends that reduces greatly and the contact resistance and the temperature rise of separated time mouth splicing position, and in bus duct, used high-quality insulating material; Thereby improved the safe reliability of bus duct, made total system more perfect.
According to GB7251.2-2006 8.2.10.1 bar, 8.2.10.2 bar and 8.2.12 bar, to carry out the structural strength checking of normal mechanical load, the structural strength checking of heavy-duty machinery load and the checking of compression resistance performance to bus duct.Its testing requirements is: a mass M is added up on the square rigid plate that hem width equals the bus duct hem width, and rigid plate is placed in the middle of the shell upper strong point.The mass M that applies can reach more than the 500kg when maximum.Traditional test method is that the stack counterweight makes an experiment on rigid plate.When mass M is big, on limited area, stack the counterweight that Pass Test requires, both wasted time and energy, and crank, security incidents such as counterweight landing take place greatly and easily in the test difficulty.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, provide a kind of rational in infrastructure, easy and simple to handle, safe and reliable, measure the intensity and the compression resistance performance test apparatus of bus duct structure accurately.
The purpose of the utility model is accomplished through following technical scheme; It comprises that one can be with the support in the middle of being placed by the examination bus duct; In support, dispose a rigid plate that places the bus duct shell upper; One is positioned over the device for exerting on the rigid plate, and between device for exerting and support, is placed with pressure transducer, and the output signal line of this pressure transducer is connected with a pressure-measuring device.
Described support is the casing shape, is used to keep being tried relative position and the reacting force between bus duct and the pressure transducer; Rigid plate of configuration is the square block that a hem width equals the bus duct hem width in it.
Described device for exerting is between by examination bus duct and pressure transducer, to produce a pressure;
Described pressure transducer is to convert the pressure that device for exerting produces to electrical signal transfer to pressure-measuring device;
Described pressure-measuring device is that the signal of pressure transducer is measured and shown.
The utility model is mainly used in the test to bus duct structural strength, compression resistance performance, and the test pressure that applies is 0 ~ 5000kg, but step-less adjustment accurately shows; Can be applicable to the structural strength of various models, specification bus duct, the testing requirements of compression resistance performance.Its maximum characteristics be simple and reasonable for structure, easy to operate, applicability is strong, data are accurate, safe and reliable.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: as shown in Figure 1: the utility model comprises that one can be with the support 2 in the middle of being placed by examination bus duct 1; In support 2, dispose a rigid plate 3 that places the bus duct shell upper; One is positioned over the device for exerting 4 on the rigid plate 3; And between device for exerting 4 and support 2, being placed with pressure transducer 5, the output signal line of this pressure transducer 5 is connected with a pressure-measuring device 6.
Described support 2 is the casing shape, is used to keep being tried relative position and the reacting force between bus duct 1 and the pressure transducer 5; Rigid plate 3 of configuration is the square block that a hem width equals bus duct 1 hem width in it.
Wherein said support is used to keep being tried relative position and the reacting force between bus duct and the pressure transducer;
Described device for exerting is between by examination bus duct and pressure transducer, to produce a pressure;
Described pressure transducer is to convert the pressure that device for exerting produces to electrical signal transfer to pressure-measuring device;
Described pressure-measuring device is that the signal of pressure transducer is measured and shown.
During use, the bus duct that will be tried places in the middle of the described support, and the square rigid plate that a hem width is equaled the bus duct hem width is placed on the testing position place of bus duct shell upper;
Described device for exerting is put on the rigidity plate, places described pressure transducer between device for exerting and the support; The output signal line of pressure transducer is connected with described pressure-measuring device;
Open the power supply of pressure-measuring device; Select suitable measurement range, press the slow pressure boost of device for exerting, read pressure-measuring device numerical value;, pressure begins to carry out timing when meeting the requirements of the M value with stopwatch; And the pressure of in 5 fens clock times of standard-required, finely tuning device for exerting discharges the pressure of device for exerting, off-test to guarantee required M value after 5 minutes.
Claims (2)
