Description

TECHNICAL FIELD

[0001] The utility model relates to shear wall detection technical field, concretely relates to a shear wall multidimensional parameter detection device. BACKGROUND

[0002] Shear wall is also called wind resisting wall, anti-seismic wall or structural wall, and is mainly used for bearing horizontal load and vertical load caused by wind load or earthquake in houses or structures to prevent shear failure of the structure.

[0003] Steel plate shear wall is an important structural form of shear wall, and is widely used in high-rise and super high-rise steel structure buildings, industrial buildings, stadiums, bridges and other structures. Steel plate shear wall is mainly composed of steel plate and steel frame, and has small wall thickness and small space occupation. The steel plate shear wall is connected by one or more steel plates through screwing or welding in different ways, so that the overall connectivity of the steel plate shear wall has great influence on the overall performance of the steel plate shear wall.

[0004] At present, after the steel plate shear wall is manufactured, the steel plate shear wall is mainly detected through visual inspection, coloring flaw detection and vibration test to find hidden cracks and poor bonding in the steel plate shear wall. However, due to the limitation of equipment, the workers need to move to each part of the steel plate shear wall by using the climbing frame to knock to obtain multidimensional vibration parameters, which not only has low efficiency, but also needs multiple knocking to achieve the expected vibration effect.

[0005] Therefore, a shear wall multidimensional parameter detection device is designed, which can quickly provide stable vibration source at the required position of the steel plate shear wall, thereby improving the multidimensional parameter detection efficiency of the steel plate shear wall. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a shear wall multidimensional parameter detection device to solve the problems described in the background.

[0007] The technical scheme of the utility model is implemented as follows:

[0008] The utility model provides a kind of shear wall multidimensional parameter detection device, including bottom plate and mobile wheel being located bottom plate bottom, bottom plate upper end is equipped with lifting mechanism, lifting mechanism is equipped with transverse plate being liftable, transverse plate is equipped with left and right horizontal moving mechanism, left and right horizontal moving mechanism is equipped with slider being movable left and right, slider is fixedly equipped with mounting plate, mounting plate is fixedly equipped with first cylinder and second cylinder, second cylinder is equipped with first impact head made of ferromagnetic material, the front end of second cylinder is equipped with impact rod, the front end of impact rod is from the front end of second cylinder and is fixed, the diameter of first impact head is greater than impact rod, the front end of second cylinder is fixedly equipped with magnetic block, the front end of magnetic block is fixedly equipped with soft pad, the rear end of impact rod is from the rear end of second cylinder when first impact head rear end and magnetic block are attached, first cylinder is equipped with sliding bin inside, first cylinder front end surface is equipped with front sliding hole, first cylinder rear end surface is equipped with rear sliding hole, the diameter of front sliding hole and rear sliding hole is less than the inside diameter of sliding bin, sliding bin is equipped with slide axle, the front end of slide axle is fixedly equipped with piston block, piston block is slidably connected on the bin wall of sliding bin, the front end of piston block is fixedly equipped with second impact head, spring is sleeved on the outside of slide axle, the front end of spring is fixedly connected with the rear end of piston block, the rear end of spring is fixedly connected with the rear end bin wall of sliding bin, when the original state of spring is kept, the front end of piston block does not resist the front end bin wall of sliding bin, second impact head extends into front sliding hole and keeps a certain distance with impact rod, slide axle is slidably arranged in rear sliding hole and is backward from rear sliding hole, slide axle rear end is also equipped with connecting plate, mounting plate is also fixedly equipped with telescopic length adjustable telescopic cylinder, the telescopic rod of telescopic cylinder is extended to rear and abuts against connecting plate.

[0009] When using the above scheme, the bottom plate is moved to the front end of the steel plate shear wall to be tested by the mobile wheel, the telescopic rod of the telescopic cylinder is controlled to extend backward to a distance according to the determined impact force, the telescopic rod abuts against the connecting plate and moves backward by a preset distance, the connecting plate drives the slide axle to move backward, the slide axle drives the piston block to move backward, the piston block pushes the spring backward to compress, the impact rod is pushed backward, so that the first impact head is attracted by the magnetic block. Then, the transverse plate is moved to the height to be knocked by the lifting mechanism, then the slider is moved to the position to be knocked by the left and right horizontal moving mechanism, the telescopic rod of the telescopic cylinder is quickly retracted, the piston block quickly moves forward under the rebounding action of the spring, when the spring is in the stretching state, the second impact head on the piston block collides with the rear end of the impact rod, the impact rod is hit forward, the first impact head is separated from the attraction of the magnetic block and is hit forward to knock the steel plate shear wall.

[0010] After the first impact head knocks the steel plate shear wall, it retreats backward under the reaction force, when the impact force is large enough, the rear end of the first impact head will abut against the front end surface of the first cylinder again and be attracted by the magnetic block, so as to prevent the first impact head from hitting the steel plate shear wall again and causing the error of vibration test. The damage of the magnetic block can be effectively prevented by setting the soft pad.

[0011] By setting the spring to maintain its original state, the front end of the piston block does not rest against the front end wall of the sliding chamber, and the second impact head extends into the front sliding hole and leaves a certain distance from the impact rod, making it difficult for the second impact head to effectively impact the impact rod after the first impact, thereby preventing the impact rod from being knocked out during the oscillation of the spring and causing a second impact on the steel plate shear wall.

Two sliding sleeves and a screw sleeve are also fixed on the horizontal plate, and the two sliding sleeves are respectively slidably mounted on the outside of the two vertical rods, and the screw sleeve is threadedly mounted on the outside of the second screw rod.

The first motor is fixed at the upper end of the transverse plate, one end of the first screw rod is connected to the first motor drive, and the first screw rod is threaded through the slider. The upper end surface of the transverse plate is also provided with a sliding groove downward, and the extension direction of the sliding groove is the same as the extension direction of the central axis of the first screw rod. The bottom of the slider is also provided with a limit block, and the limit block is slidably connected to the slide groove left and right.

[0015] When using the above solution, the slider is connected to the slide groove by sliding left and right through the limit block. When it is necessary to control the left and right movement of the sliding hole, the first motor drives the first screw rod to rotate forward or reverse, and the first screw rod drives the sliding hole to move left or right, thereby driving the sliding hole to move left or right.

[0016] A further technical solution is that a front rubber pad is further provided at the front end of the first impact head.
