Description

Technical Field

[0001] The utility model relates to the technical field of road construction detection, and more specifically to a highway roadbed and pavement deflection detection device. Background Art

[0002] Deflection is a key technical indicator for highway design and engineering quality assessment. It reflects the overall strength of each pavement layer. Excessive deflection increases deformation and makes the pavement layers more susceptible to cracking. Deflection is typically measured through deflection testing.

[0003] The installation position of the detection structure on the currently used pavement deflection detection equipment is usually fixed. When it is necessary to detect different parallel positions, the horizontal equipment needs to be moved as a whole. In this way, there is a position offset during the movement, and angular position operation is required, which increases the time of the detection operation and affects the structural coordination effect. In view of this, we propose a highway roadbed and pavement deflection detection equipment. Utility Model Content

Two connecting blocks are fixed on the side of the L-shaped limit part close to the indicator part, and a scale combined with the indicator part is fixedly installed between the two connecting blocks.

[0007] The utility model combines the detection part with the movable plate, which can drive the L-shaped limit part to move synchronously when the detection part moves laterally. In this way, the deflection of the road surface at different lateral positions can be detected by lateral translation, eliminating the step of adjusting the movement of the overall structure. In this way, the level state can be maintained during the movement, the time required for position adjustment due to offset is reduced, and the speed of deflection detection is effectively improved.

[0008] Preferably, a movable groove is provided transversely through the top of the movable platform, and two limiting grooves are symmetrically provided on the top of the movable platform with the movable groove as the center.

[0010] Preferably, the indicator comprises extension bars fixed on both sides of the fixing rod, the side of the extension bar facing the scale is fixed with a connecting rod, and the side end of the connecting rod is fixed with an indicator mark combined with the scale.

[0011] Preferably, a fixing seat is fixedly provided at the lower end of the fixing rod, a rolling ball is rotatably mounted on the bottom of the fixing seat, and a limiting plate fixedly connected to a compression spring is fixedly provided on the rod wall of the fixing rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The present invention combines the detection member with the movable plate, which can drive the L-shaped limit member to move synchronously when the detection member moves horizontally. In this way, the deflection of the road surface at different lateral positions can be detected by lateral translation, eliminating the step of adjusting the movement of the overall structure. In this way, the horizontal state can be maintained during the movement, reducing the time required to adjust the position due to offset, and effectively improving the speed of deflection detection.

[0014] 2. The present invention can also quickly understand the deflection spacing when the detection part moves downward through the combination of the indicator mark and the scale, which is convenient for quickly understanding the deflection of the road surface. The cooperation between the L-shaped limiter and the detection part can limit the initial position of the rolling ball, which can improve the measurement accuracy during the detection process, eliminate the step of adjusting the detection point, and further improve the detection speed.

[0021] Detection piece 2 includes fixed rod 201 passing through movable slot 101, and indicating piece 4 is fixedly arranged on the side of L-shaped limiting piece 3 close to detection piece 2, and two connecting blocks 301 are fixedly arranged on the side of L-shaped limiting piece 3 close to detection piece 4, and scale 302 combined with indicating piece 4 is fixedly installed between two connecting blocks 301;The connection of indicating piece 4 and scale 302 can drive indicating piece 4 to move downward synchronously when fixed rod 201 moves downward, so that the scale at different positions of scale 302 can be indicated, so that the distance of deflection can be quickly understood.

[0022] In the embodiment of the utility model, the top of mobile station 1 is transversely provided with movable slot 101 abutting with the rod wall of fixed rod 201, and two limiting slots 102 are symmetrically provided in the top of mobile station 1 with movable slot 101 as center;The provision of movable slot 101 can limit the angle of deviation when detection piece 2 moves transversely, and the provision of limiting slot 102 can facilitate the transverse movement of movable plate 5.

[0023] In an embodiment of the present invention, positioning rods 501 passing through the limiting grooves 102 are fixedly installed on both sides of the top of the movable plate 5, and the top of the positioning rod 501 on one side is fixedly connected to the bottom of the L-shaped limiting member 3, and the top of the positioning rod 501 on the other side is fixedly provided with a limiting block 502 that fits with the top of the movable platform 1; the positioning rod 501 passing through the limiting groove 102 can limit the installation position of the movable plate 5, and the connection between the L-shaped limiting member 3 and the positioning rod 501 can simultaneously fix the positions of the L-shaped limiting member 3 and the movable plate 5 on both sides of the movable platform 1, and the setting of the limiting block 502 can limit the position of the positioning rod 501 on the other side, so that the movable plate 5 can move smoothly laterally.

[0024] In an embodiment of the present invention, the indicator 4 includes an extension bar 401 fixed on both sides of the fixed rod 201, and a connecting rod 402 is fixedly provided on the side of the extension bar 401 facing the scale 302, and an indicator mark 403 combined with the scale 302 is fixedly provided on the side end of the connecting rod 402; through the cooperation between the extension bar 401 and the connecting rod 402, the indicator mark 403 can be installed on the outside of the scale 302.

[0025] In an embodiment of the present utility model, a fixing seat 202 is fixedly provided at the lower end of the fixing rod 201, and a rolling ball 203 is rotatably installed at the bottom of the fixing seat 202.

[0026] Working Principle: This embodiment provides a highway roadbed and pavement deflection detection device. When in use, the entire device is first moved to the road surface to be detected. During the movement, the rolling ball 203 with a rolling design can move synchronously to reduce resistance. When the rolling ball 203 moves to the deflected part, the pressure on the compression spring 6 is reduced, thereby pushing the fixed rod 201 downward, causing the indicator 4 at the top of the fixed rod 201 to move downward outside the scale 302. The deflection distance can be directly understood by the downward movement distance, thereby achieving the effect of road surface deflection detection. When it is necessary to adjust the detection position laterally based on the current detection point, the top of the detection member 2 can be pushed to cause the movable plate 5 to drive the L-shaped limit member 3 to move synchronously, so that the rolling ball 203 can roll laterally to the position of the next detection point. In this way, the movable groove 101 and the limit groove 102 can maintain the effect of parallel lateral movement, so that the positions of other detection points correspond to the initial detection point. This can effectively increase the detection speed, reduce the position adjustment steps, and achieve the effect of saving time. The coordination of the overall structure can effectively improve the effect of road surface deflection detection.
