Problems solved by technology

And the currently commonly used micro-drilling resistance meter has a length of about 70-80cm and a mass of about 10-15kg. Therefore, these detection positions are purely hand-held by manpower. Greatly increase the intensity of human work, and due to artificial shaking and moving, it may cause errors in the collection of test data, and even cause damage to instruments and equipment

Embodiment Construction

[0031] In view of the micro-drilling resistance detection requirements of different component sizes, shapes, positions, etc. in the ancient building inspection site, the fixed bracket device can be adjusted in shape according to the needs and site conditions, so as to meet the suitability requirements of the site work. The following situations are common:

[0032] (1) When performing radial and horizontal micro-drilling resistance testing on the lower position of the column member, see Figure 7. Place the micro-drill resistance meter in the spring slot 2 of the support, and bind the middle flexible fixing band 3 around the micro-drill resistance meter, adjust the adjustable buckle 9 to control the length of the strap, so that the micro-drill resistance meter Reliable fixation in the card slot 2 prevents relative sliding. The front flexible fixed belt 1 is bound around the cross-section of the wooden column to be tested, and the adjustable buckle 9 is adjusted to control the...

Abstract

The invention discloses a wooden micro drill resistance dynamometer fixing bracket device for field detection of wood members of ancient architectures, belonging to the technical field of ancient architecture protection. The device consists of a front-end flexible fixing band (1), support spring clamping grooves (2), a middle flexible fixing band (3), a level (4), a hydraulic telescopic diagonal bar (5), a rear-end telescopic rigid fixing bracket (6), a protractor (7) and a hinged supporting pad (8). According to the device disclosed by the invention, detection equipment can be effectively fixed and supported in the on-site nondestructive testing process of the ancient architectures according to different detection site conditions, a measuring angle is quantitatively determined, the detection precision is improved, data acquisition errors and instrument damage risks caused by manual jitter are reduced, the manual working strength and operational risk are reduced, and a micro drill resistance dynamometer is assisted to perform field data acquisition. According to the device, adjustment combinations of different shapes can be performed according to different field conditions of horizontal members, vertical members, chordwise pin insertion, radial pin insertion and the like in the ancient architectures.

Description

technical field [0001] The invention relates to an auxiliary test device which is beneficial to on-site detection test of wood micro-drilling resistance and is combined with existing instruments and equipment for data collection. The invention belongs to the technical field of wood internal defect and mechanical performance testing and ancient building protection. Background technique [0002] The micro-drill resistance meter is a commonly used instrument and equipment currently used in the field of on-site detection of non-(micro) damage to wooden components of ancient buildings. The principle is that the relative resistance generated by the motor driven by the motor to drill into the wood at a constant rate reflects the change in its density. The resistance parameters generated by the drill in the wood are collected and calculated by the computer system, and the resistance curve is displayed. image. Based on the displayed resistance curve and combined with wood science k...
