The component clamping device is mainly formed by three components, thereby being simple in structure and convenient to manufacture. At least three cushion blocks can guarantee that the placement of a to-be-tested composite pipe meets requirements.
Description
Technical field
The utility model relates to member clamping device in a kind of composite material tube axial compression test.
Background technology
Along with the high speed development of urban construction, land resource is more and more rare, and the people's environmental protection ideas also constantly strengthens.At present, transmission line of electricity becomes very difficult at aspects such as policy processing, removing and resettlement, saving corridors, and this also starts just State Grid Corporation of China for 2009 and carries out one of main starting point of composite material pole tower research.
Composite material pole tower is the novel shaft tower that in transmission tower, main bearing member or cross-arm partly adopt compound substance, make full use of that compound material insulation is good, intensity is high, lightweight, corrosion-resistant, easy care and the advantage such as designability is strong, be the novelty application of advanced composite material (ACM) in transmission tower structure.For the design in shaft tower provides reference to compound substance, must carry out bearing capacity and the stability factor that axial compression experiment has obtained composite pipe to forming the composite material tube of composite material pole tower.
Existing power transmission and transformation composite bar tower member is when carrying out axial compression experiment, the end of composite pipe is to take bonding method to be connected with experimental facilities, the end and the steel plate that are about to composite pipe bond together, then together with steel plate being bolted with ball pivot, the shortcoming of this way is that between composite pipe and steel plate, bond strength is inadequate, when the local stress of composite pipe end is excessive, thereby can cause between local fiber and resin, cracks and cause pipe fitting end to destroy.
Utility model content
The purpose of this utility model is to provide member clamping device in a kind of composite material tube axial compression test, can effectively solve existing scheme and in composite material tube axial compression test, be difficult for fixing, and causes the inaccurate problem of test figure.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: member clamping device in a kind of composite material tube axial compression test, comprise the ring flange that is connected with ball pivot in last item testing machine, be set in pipe in ring flange, be arranged on the cushion block that in pipe, the compound substance end surfaces centre of form to be measured is overlapped with the ring flange end face centre of form, described cushion block has three at least.
Preferably, the center of described pipe bottom surface and the center superposition of ring flange end face, bottom and the ring flange of described pipe weld together; Be convenient to control the position of composite material tube to be measured to obtain measurement data accurately, adopt the simple fastness of mode technique of welding high.
Preferably, the length of described pipe is 20cm to 30cm and is at least 1/5 of pipe diameter; Can obtain the support to composite material tube the best to be measured.
Preferably, described ring flange is perpendicular to the axis of pipe; After composite material tube to be measured is loaded onto in correct horizontal level.
Compared with prior art, the utility model has the advantages that: utilize ring flange to dock with testing machine, composite material tube to be measured is fixed in pipe, by cushion block, adjust composite material tube to be measured in position accurately, finally utilize resin glue that composite material tube to be measured is fixed in pipe, thereby can obtain test data accurately, this device mainly forms simple in structure by three parts, easily manufactured, the placement of at least three cushion block guarantee composite material tubes to be measured can meet the requirements.

Fig. 2 is the structural representation of ring flange and pipe in member clamping device in the test of a kind of composite material tube last item of the utility model.
Embodiment
Consult Fig. 1, Fig. 2, member clamping device in a kind of composite material tube axial compression test, comprise the ring flange 1 being connected with ball pivot in last item testing machine, be set in the pipe 2 in ring flange 1, be arranged on the cushion block 4 that in pipe 2, the composite material tube 3 end face centres of form to be measured is overlapped with the ring flange 1 end face centre of form, described cushion block 4 has three at least, the center of described pipe 2 bottom surfaces and the center superposition of ring flange 1 end face, the bottom of described pipe 2 and ring flange 1 weld together, the length of described pipe 2 is 20cm to 30cm and is at least 1/5 of pipe 2 diameters, described ring flange 1 is perpendicular to the axis of pipe 2, described pipe 2 is steel pipe.
A using method for member clamping device in composite material tube axial compression test, comprises the following steps successively:
A. clamping device is enclosed within to one end of composite material tube 3 to be measured, make composite material tube 3 end faces to be measured concordant with ring flange 1 end face, add cushion block 4, the composite material tube 3 end face centres of form to be measured are overlapped with the ring flange 1 end face centre of form, cushion block 4 adds quantity to be no less than three, in the gap between composite material tube 3 to be measured and pipe 2, fill with epoxide-resin glue again, the filling epoxide-resin glue degree of depth and pipe 2 are equal in length;
B. the other end of composite material tube 3 to be measured also operates by the mode in steps A;
C. etc. after the epoxide-resin glue in steps A and step B all solidifies, by ring flange 1 together with in test machine, ball pivot is bolted on.
Utilize ring flange 1 to dock with testing machine, composite material tube 3 to be measured is fixed in pipe 2, by cushion block 4, adjust composite material tube 3 to be measured in position accurately, finally utilize resin glue that composite material tube 3 to be measured is fixed in pipe 2, thereby can obtain test data accurately.
