Description

Technical Field

[0001] The present invention relates to the technical field of building construction inspection, and particularly to a device for detecting the strength of inorganic cementitious materials. Background Art

[0002] In the field of construction engineering, inorganic cementitious materials play a crucial role like a cornerstone. To ensure that inorganic cementitious materials meet engineering standards, strength detection is of vital importance. Currently, a pendulum hammer impactor is one of the commonly used detection tools. It mainly measures the depth of the impact pin inserted into the wall by using an existing distance measuring device and calculates the measured data during the process of the impact hammer on the device hitting the impact pin during the free fall of the pendulum hammer, so as to realize the detection of the compressive strength of the wall. However, it exposes many inconveniences and defects in actual operation.

[0003] Chinese Patent Application CN118464675A discloses a device for detecting the strength of durable concrete, including a base, on which a pendulum hammer and a nail measuring seat are installed. The base is provided with a plurality of first channels, and each first channel is configured with a first movable rod. One end of the first movable rod is connected to the inner wall of the first channel through an elastic member, and the other end of the first movable rod extends out of the first channel and is provided with a patch; a locking member is installed on the base at the position of the pendulum hammer, and a driving member is also installed on the pendulum hammer. The driving member is configured to drive and switch the state of the locking member. A triggering member is arranged in the first channel. When all the patches are triggered to start the triggering member, the locking member is automatically controlled to switch to the unlocked state, realizing the unlocking of the pendulum hammer and the subsequent swinging and hitting detection work, thereby improving work efficiency.

[0004] However, after each measurement, the pendulum hammer will stay at the position after hitting, and it is necessary to manually lift the pendulum hammer to the initial position. This process not only consumes manpower but also has low efficiency. Especially in large-scale detection tasks or engineering scenarios with tight time, frequent manual reset operations greatly slow down the detection progress. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0027] As Figures 1 to 5 shown, an inorganic cementitious material strength detection device is provided in an embodiment of the present invention, which includes a vertical plate 101, a mounting block 102, a rotating shaft 103, a pendulum and a reset mechanism. The vertical plate 101 can contact the surface of the object to be measured. Let the surface of the vertical plate 101 contacting the object to be measured be a vertical first surface; the mounting block 102 is fixedly installed on the surface of the vertical plate 101 away from the first surface. The rotating shaft 103 is rotatably arranged on the mounting block 102, and the axis of the rotating shaft 103 extends in the horizontal direction and is parallel to the first surface. One end of the pendulum is sleeved on the rotating shaft 103, and the pendulum is fixedly connected to the rotating shaft 103. A measuring nail 104 is slidably arranged on the vertical plate 101 along a first direction. The first direction extends in the horizontal direction and is perpendicular to the first surface. The measuring nail 104 can penetrate the surface of the object to be measured, and the measuring nail 104 is located below the mounting block 102; the pendulum has an initial position and a striking position. When the pendulum is in the initial position, it has potential energy to move closer to the striking position. When the pendulum is in the striking position, it can collide with the measuring nail 104; the reset mechanism includes a push rod 127, an adjusting component and a transmission component. The push rod 127 is slidably arranged on the vertical plate 101 along the first direction, and the push rod 127 penetrates the vertical plate 101 and can abut against the surface of the object to be measured. When the vertical plate 101 approaches the surface of the object to be measured, the push rod 127 first contacts the surface of the object to be measured. The adjusting component is used to adjust the pressure between the push rod 127 and the surface of the object to be measured when the vertical plate 101 contacts the surface of the object to be measured. The pressure between the vertical plate 101 and the surface of the object to be measured is less than the pressure between the push rod 127 and the surface of the object to be measured; when the vertical plate 101 approaches the surface of the object to be measured, the transmission component can make the pendulum move from the striking position to the initial position through the relative movement between the push rod 127 and the vertical plate 101.

[0028] A push rod 127 is provided, which can perform rough positioning before the vertical plate 101 contacts the surface of the object to be measured. Through the cooperation between the transmission component, the pendulum and the push rod 127, when the vertical plate 101 approaches the surface of the object to be measured, the pendulum can reset. When detecting multiple points, the continuity of the detection process can be improved, the operation steps can be reduced, and the convenience of use can be enhanced; an adjustment component is provided. When detecting an object with a relatively large surface roughness of the object to be measured, the friction between the vertical plate 101 and the surface of the object to be measured can make the vertical plate 101 relatively stable, and the contact pressure between the push rod 127 and the surface of the object to be measured can be appropriately reduced, reducing the burden on the operator; when detecting an object with a relatively small surface roughness of the object to be measured, the vertical plate 101 is more likely to slide relative to the surface of the object to be measured, and the contact pressure between the push rod 127 and the surface of the object to be measured can be appropriately increased to improve the stability of the vertical plate 101 on the surface of the object to be measured.

[0029] In this embodiment, the adjustment component includes a limit block 105, a limit ring 106 and a first spring 107. The limit block 105 is slidably arranged on the mounting block 102 along a first direction, and the limit block 105 is sleeved on the push rod 127. The limit block 105 is slidably connected to the push rod 127. A U-shaped plate 108 is provided on the mounting block 102. The two ends of the U-shaped plate 108 are respectively fixedly connected to the mounting block 102. A hole is formed by enclosing between the U-shaped plate 108 and the mounting block 102. The limit block 105 slides in the hole along the first direction. A first bolt 109 is threadedly connected to the U-shaped plate 108. The first bolt 109 can abut against the limit block 105. When the first bolt 109 abuts against the limit block 105, the limit block 105 cannot move relative to the vertical plate 101. The limit ring 106 is sleeved on the push rod 127, and the limit ring 106 is fixedly connected to the push rod 127. Both the limit ring 106 and the limit block 105 are on the same side of the mounting block 102 as the vertical plate 101. The first spring 107 is sleeved on the push rod 127, and the two ends of the first spring 107 are respectively connected to the limit block 105 and the limit ring 106. The first spring 107 is always in a compressed state. The limit ring 106 abuts against the vertical plate 101 when the push rod 127 is not in contact with any object. By moving the position of the limit block 105 on the mounting block 102 and then limiting the limit block 105 through the first bolt 109, the elastic potential energy of the first spring 107 can be changed, thereby changing the pressure between the push rod 127 and the surface of the object to be measured when the vertical plate 101 contacts the surface of the object to be measured.

[0030] In this embodiment, the transmission assembly includes a gear 110 and a rack plate 111. The gear 110 is an incomplete gear 110. The gear 110 is sleeved on the rotating shaft 103, and the gear 110 can rotate synchronously with the rotating shaft 103. The rack plate 111 is fixedly installed on the push rod 127 and the rack plate 111 is located below the gear 110. The rack plate 111 can mesh with the gear 110. Both the gear 110 and the rack plate 111 are located on the side of the push rod 127 away from the limit block 105 in the first direction. If the pendulum is in the striking position and when the vertical plate 101 approaches the surface of the object to be measured, the push rod 127 in contact with the surface of the object to be measured will slide relative to the vertical plate 101 in the first direction. At this time, the rack plate 111 can mesh with the gear 110 after moving along the first direction with the push rod 127. The rack plate 111 can drive the rotating shaft 103 to rotate through the gear 110, and the rotating shaft 103 drives the pendulum to move towards the initial position of the pendulum; if the pendulum is in the striking position and when the vertical plate 101 moves away from the surface of the object to be measured, the push rod 127 in contact with the surface of the object to be measured will drive the rack plate 111 to move relative to the vertical plate 101 in the first direction under the action of the first spring 107. At this time, the rack plate 111 will mesh with a small number of teeth of the gear 110 and drive the pendulum to continue to move in the direction away from its initial position through the rotating shaft 103. Then the rack plate 111 disengages from the gear 110 until the limit ring 106 abuts against the vertical plate 101.

[0031] In this embodiment, a rubber pad 112 is provided at one end of the push rod 127 in contact with the surface of the object to be measured. The rubber pad 112 can increase the friction between the push rod 127 and the surface of the object to be measured and improve the stability of the vertical plate 101 on the surface of the object to be measured.

[0032] In this embodiment, a groove 113 is formed on the first surface. The push rod 127 is slidably disposed in the groove 113. The rubber pad 112 can be completely accommodated in the groove 113. When the vertical plate 101 contacts the surface of the object to be measured, the rubber pad 112 is flush with the plane of the vertical plate 101. If the plane of the position where the rubber pad 112 is located is higher than other positions of the surface of the object to be measured, the rubber pad 112 can still be accommodated in the groove 113, so that the vertical plate 101 can be in full contact with the surface of the object to be measured and enhance its applicability.

[0033] In this embodiment, the mounting block 102 is provided with a receiving groove 114. A second spring 115 that can expand and contract in the first direction is arranged in the receiving groove 114. A first clamping plate 116 is slidably arranged on the vertical plate 101 in the first direction. One end of the first clamping plate 116 extends into the receiving groove 114 and is connected to one end of the second spring 115. The pendulum includes a connecting rod 117 and a hammer body 118. One end of the connecting rod 117 is sleeved on the rotating shaft 103 and is fixedly connected to the rotating shaft 103. A clamping groove 119 is formed in the connecting rod 117. The first clamping plate 116 can be clamped with the connecting rod 117 through the clamping groove 119. When the first clamping plate 116 is clamped with the connecting rod 117, an included angle is provided between the connecting rod 117 and the vertical plate 101, so as to prevent the situation that after the first clamping plate 116 is separated from the connecting rod 117, the connecting rod 117 does not rotate around the rotating shaft 103 because the centers of gravity of the connecting rod 117 and the hammer body 118 and the axis of the rotating shaft 103 are located on the same vertical plane. When the first clamping plate 116 is clamped with the connecting rod 117, the pendulum is in the initial position. Two handles 120 are fixedly installed on the surface of the vertical plate 101 where the mounting block 102 is provided. The two handles 120 are respectively located at both ends in the axial direction of the rotating shaft 103. A dial plate 121 is arranged on the connecting rod 117. The dial plate 121 extends along the axial direction of the rotating shaft 103 and penetrates through the mounting block 102. And the dial plate 121 is slidably connected to the mounting block 102 in the first direction. The end of the dial rod far from the first clamping plate 116 is close to the handle 120. The operator holds the two handles 120 with both hands respectively, and then can push the dial plate 121 with fingers to make the first clamping plate 116 separated from the connecting rod 117. The hammer body 118 drives the connecting rod 117 to rotate around the rotating shaft 103 under the action of its own gravity and rotates to the striking position to strike the nail 104.

[0034] In this embodiment, a third spring 122 and a second clamping plate 123 are arranged on the mounting block 102. The third spring 122 is arranged in the receiving groove 114 and is located above the first clamping plate 116. The third spring 122 can expand and contract in the first direction. The second clamping plate 123 is slidably arranged on the mounting block 102 in the first direction. And one end of the second clamping plate 123 extends into the receiving groove 114 and is connected to the third spring 122. When the pendulum is in the initial position, the connecting rod 117 is in contact with the second clamping plate 123. In order to ensure that the pendulum can move smoothly to the initial position, before the first surface and the surface of the object to be measured approach each other and are about to contact, the rack plate 111 will drive the gear 110 to rotate and drive the connecting rod 117 to cross the vertical plane where the axis of the rotating shaft 103 is located through the rotating shaft 103. At this time, the first clamping plate 116 slides in the clamping groove 119, and the second clamping plate 123 abuts against the connecting rod 117. The rack plate 111 and the gear 110 are in a tooth-beating state under the action of the third spring 122 and last for a short period of time. Then the rack plate 111 will gradually move away from the gear 110 and no longer contact the gear 110. The second clamping plate 123 will then push the connecting rod 117 to cross the vertical plane where the axis of the rotating shaft 103 is located again, so that the first clamping plate 116 is clamped with the connecting rod 117.

[0035] In this embodiment, a spirit level 124 is provided on the upper surface of the mounting block 102. When the vertical plate 101 cannot be vertically placed when the measured surface of the object is uneven, the vertical plate 101 can be made vertical by observing the spirit level 124, thereby improving the accuracy of the detection.

[0036] In this embodiment, three second bolts 125 are provided on the vertical plate 101. The three second bolts 125 respectively penetrate the vertical plate 101 along the first direction and are threadedly connected to the vertical plate 101. Two of the second bolts 125 are located on the same horizontal plane and above the other second bolt 125. The two second bolts 125 located above are on both sides of the second bolt 125 below in the axial direction of the rotating shaft 103. The second bolt 125 below the two second bolts 125 is directly below or directly above the measuring pin 104. When the measured surface of the object is uneven and the vertical plate 101 is adjusted to be vertical by the spirit level 124, the second bolt 125 can be rotated to make the second bolt 125 contact the measured surface of the object, providing a fulcrum for the operator and facilitating use.

[0037] In this embodiment, a protective frame 126 is provided on the mounting block 102. The protective frame 126 is U-shaped. The two ends of the protective frame 126 are respectively connected to the mounting block 102, and the two ends of the protective frame 126 are on both sides of the pendulum in the axial direction of the rotating shaft 103. When the pendulum exchanges between the initial position and the striking position, it can pass through between the protective frames 126. The swinging range of the pendulum can be directly seen from the protective frame 126, avoiding the influence of external factors on the swinging of the pendulum.

[0038] The working principle of the inorganic cementitious material strength detection device provided by the above embodiment is as follows:

[0039] First, mark the position on the surface of the object to be measured where the measuring pin 104 is to be inserted. Then, the operator holds the handle 120 and moves the vertical plate 101, causing the measuring pin 104 on the vertical plate 101 to move to this position. Then, the vertical plate 101 is pushed in the first direction so that the push rod 127 contacts the surface of the object to be measured. Continuing to push the vertical plate 101, the push rod 127 remains stationary relative to the surface of the object to be measured, and the push rod 127 slides relative to the vertical plate 101, and the first spring 107 is compressed (the distance between the limit block 105 and the vertical plate 101 can be adjusted according to the friction force between the surface of the object to be measured and the vertical plate 101, thereby changing the initial elastic force of the first spring 107 and the pressure between the push rod 127 and the surface of the object to be measured when the vertical plate 101 contacts the surface of the object to be measured, improving the operating comfort of the operator). Then, the gear 110 gradually approaches the rack plate 111 and finally meshes with the rack plate 111. While the gear 110 rolls on the rack plate 111, it drives the connecting rod 117 to rotate through the rotating shaft 103. The connecting rod 117 drives the hammer body 118 to rotate upward around the rotating shaft 103, and the connecting rod 117 and the hammer body 118 continue to rotate through the protective frame 126. When the connecting rod 117 rotates to the vertical state, at this time, the first clamping plate 116 has been inserted into the card slot 119 under the action of the second spring 115, and the connecting rod 117 and the second clamping plate 123 are in a butting state under the action of the third spring 122. The rack plate 111 and the gear 110 can be disengaged from meshing. After the rack plate 111 and the gear 110 are disengaged from meshing, the connecting rod 117 rotates downward under the thrust of the second clamping plate 123, and the rack plate 111 and the gear 110 are meshed again. As the vertical plate 101 approaches the surface of the object to be measured, the rack plate 111 and the gear 110 are in a state of tooth beating until after the rack plate 111 moves away from the gear 110, the connecting rod 117 drives the hammer body 118 to rotate downward to the initial position under the push of the second clamping plate 123. At this time, the first clamping plate 116 is clamped with the connecting rod 117 through the card slot 119, and the connecting rod 117 is maintained at the initial position.

[0040] Continue to push the vertical plate 101 until the vertical plate 101 contacts the surface of the object to be measured. Then, observe the spirit level 124. If the vertical plate 101 is not in the vertical state, the vertical plate 101 is made vertical by adjusting the second bolt 125. Then, push the dial plate 121. The dial plate 121 drives the first clamping plate 116 to compress the second spring 115, and the first clamping plate 116 slides out of the card slot 119. The hammer body 118 drives the connecting rod 117 to swing downward and strike the measuring pin 104, and the measuring pin 104 pierces the surface of the object to be measured.
