Description

Technical Field

[0001] This utility model relates to the field of construction testing technology, specifically a concrete testing device for highway bridge construction. Background Technology

[0002] Concrete construction of highway bridges is a complex and meticulous process involving multiple steps and technical requirements to ensure the safety, durability, and functionality of the final structure.

[0003] During concrete construction, it is necessary to test the concrete's fluidity and hardness to ensure it meets construction standards. Concrete fluidity testing requires a slump test device to ensure proper filling of the formwork. Existing slump test devices require pouring concrete into the device, compacting it with a tamping rod, and then lifting the slump cylinder to observe the slump. However, the compaction and lifting of the cylinder can easily cause collisions between the concrete and the cylinder, potentially affecting the slump test data. Furthermore, the free fall of the concrete during measurement results in inconsistent test point locations, making it difficult to locate using a measuring ruler. Therefore, we propose a concrete testing device for highway bridge construction. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete testing device for highway bridge construction, comprising a slump test cylinder and a feeding funnel. Two sets of lifting handles are fixedly connected to the outside of the slump test cylinder. The feeding funnel is shaped like a frustum and is inserted into the top of the slump test cylinder. An auxiliary lifting mechanism is provided below the slump test cylinder to prevent it from tilting during lifting. A test ruler measuring and positioning mechanism for positioning the measuring position of the test ruler is sleeved on the top of the auxiliary lifting mechanism. Foot pedals are fixedly connected to both sides of the bottom of the auxiliary lifting mechanism.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a concrete testing device for highway bridge construction, including a slump test cylinder 1 and a feeding funnel 3. Two sets of lifting handles 2 are fixedly connected to the outside of the slump test cylinder 1. The feeding funnel 3 is shaped like a frustum and is inserted into the top of the slump test cylinder 1. An auxiliary lifting mechanism 4 is provided below the slump test cylinder 1 to prevent it from tilting during lifting. A test ruler measuring and positioning mechanism 5 for positioning the measuring position of the test ruler is sleeved on the top of the auxiliary lifting mechanism 4. Foot pedals 6 are fixedly connected to both sides of the bottom of the auxiliary lifting mechanism 4.

[0019] The auxiliary lifting mechanism 4 is used to position the slump test cylinder 1. The feed funnel 3 is then used to easily put concrete into the slump test cylinder 1. After the concrete is compacted, step on the foot pedal 6 and pull the lifting handle 2 to move the slump test cylinder 1 up along the auxiliary lifting mechanism 4. This lifting method can avoid the slump test cylinder 1 shaking due to manual lifting. After the lifting and removal is completed, the test ruler measurement and positioning mechanism 5 is placed on the auxiliary lifting mechanism 4, which makes it easier to find the measurement position of the concrete and facilitates the measurement of the concrete slump.

[0020] Please see Figure 1 , Figure 2 and Figure 3The slump test cylinder 1 includes a cylinder body 7, a limiting plate 8, and a sliding groove 9. The limiting plates 8 are fixedly connected to both ends of the bottom of the cylinder body 7. The sliding groove 9 is provided on the limiting plate 8. The auxiliary lifting mechanism 4 includes a positioning frame 10, a connecting seat 11, a limiting rod 12, a pad 13, and a connecting rod 14. Two sets of positioning frames 10 are fixedly connected to the inner wall of the positioning frame 10. The limiting rod 12 inserted into the positioning frame 10 is fixedly connected to the top of the positioning frame 10. The pad 13 is fixedly connected to the top of the limiting rod 12. The top of the pad 13 is located on the same horizontal plane as the top of the cylinder body 7. The connecting rod 14 is fixedly connected to the top of the pad 13.

[0021] During the installation of the cylinder 7, the sliding groove 9 on the limiting plate 8 is inserted into the outside of the limiting rod 12, and then concrete is filled into the inside of the cylinder 7. When the cylinder 7 needs to be lifted, the cylinder 7 and the limiting plate 8 can move upward along the limiting rod 12, which can prevent the cylinder 7 from shaking when it is lifted. The test ruler measuring and positioning mechanism 5 can pass through the outside of the connecting rod 14 and overlap the top of the pad block 13 for positioning.

[0022] Please see Figures 1-4 The test ruler measuring and positioning mechanism 5 includes a fixed plate 15, a fixed groove 16, an adjustment groove 17, a positioning plate 18, and a limiting block 19. The fixed plate 15 has two sets of fixed grooves 16 at both ends that are inserted into the outside of the connecting rod 14. The fixed plate 15 has an adjustment groove 17. The bottom of the positioning plate 18 is fixedly connected to a limiting block 19 that is inserted into the adjustment groove 17.

[0023] After the cylinder 7 is lifted, the fixing groove 16 on the fixing plate 15 is inserted into the outside of the connecting rod 14 and overlapped on the pad 13. Then, the limiting block 19 below the positioning plate 18 is inserted into the adjustment groove 17. Then, according to the test point, the limiting block 19 is slid along the adjustment groove 17 to the test point position. Then, the test ruler can be perpendicular to the positioning plate 18 to measure the data.

[0024] Please see Figure 1 , Figure 3 and Figure 4 The connecting rod 14 is shaped like a frustum, and the four corners of the limiting block 19 are all arc-shaped. The frustum shape of the connecting rod 14 makes it easy to insert the fixing groove 16 on the fixing plate 15, while the arc shape of the four corners of the limiting block 19 makes it easy to insert the limiting block 19 into the adjusting groove 17.

[0025] Please see Figure 1 and Figure 2 A rubber ring 20 is fixedly connected to the bottom of the cylinder 7. The rubber ring 20 can prevent concrete from flowing out through the bottom of the cylinder 7.

[0026] In use, firstly, the auxiliary lifting mechanism 4 positions the slump test cylinder 1. Then, the feed funnel 3 facilitates the placement of concrete into the slump test cylinder 1. After the concrete is compacted, step on the foot pedal 6 and pull the lifting handle 2 to move the slump test cylinder 1 upwards along the auxiliary lifting mechanism 4. This lifting method prevents the slump test cylinder 1 from shaking due to manual lifting. After lifting and removal, place the measuring and positioning mechanism 5 on the auxiliary lifting mechanism 4. This makes it easier to locate the concrete measurement position and facilitates slump measurement. When installing the cylinder 7, insert the sliding groove 9 on the limiting plate 8 into the outside of the limiting rod 12, and then place the concrete... Concrete is filled into the interior of the cylinder 7. When the cylinder 7 needs to be lifted, the cylinder 7 and the limiting plate 8 can move upward along the limiting rod 12, which can prevent the cylinder 7 from shaking when it is lifted. The test ruler measuring and positioning mechanism 5 can pass through the outside of the connecting rod 14 and overlap the pad 13 for positioning. After the cylinder 7 is lifted, the fixing groove 16 on the fixing plate 15 is inserted into the outside of the connecting rod 14 and overlaps the pad 13. Then, the limiting block 19 under the positioning plate 18 is inserted into the adjusting groove 17. Then, according to the test point, the limiting block 19 is slid along the adjusting groove 17 to the test point position. Then, the test ruler can be perpendicularly aligned with the positioning plate 18 to measure the data.
