Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and more specifically, to a road bridge concrete detection device. Background Art

[0002] The roadbed and pavement are structures that are subject to vehicle loads. When designing the roadbed and pavement, the mechanical properties of the roadbed and pavement materials should be correctly evaluated first, and then the pavement structure should be designed based on its mechanical properties to meet the normal driving requirements of the road within its service life. It should have sufficient strength, rigidity and stability during normal use, otherwise it will easily cause consequences such as pavement cracking.

[0003] The document with the prior art publication number CN216349930U provides a road bridge concrete structure detection device. During the process of detecting concrete, the detection platform and the concrete sample on the detection platform are located inside the protective shell, the bottom of the protective shell is in contact with the base, and as the movable plate moves downward, the protective shell slides on the outer surface of the connecting rod. At this time, the first spring is in a stretched state, and the second spring is in a compressed state. Under the reaction force of the first spring and the second spring, the protective shell is in close contact with the base, thereby avoiding the situation where concrete fragments fly out from the bottom of the protective shell during the detection process, and the splashing concrete fragments can be blocked by the buffer spring and the buffer plate to prevent the concrete fragments from damaging the protective shell, so that the protective shell can better block the concrete fragments. Compared with the current detection device, a structure for blocking concrete fragments is added, so that the concrete fragments can be blocked, and the splashing of concrete fragments is avoided, thereby avoiding the damage to the detection personnel caused by the splashing of fragments.

[0004] Although the device has many beneficial effects, the following problems still exist: when conducting strength testing on concrete blocks, if concrete blocks that do not meet the strength standards are broken, the broken concrete chips can easily fall into the guide groove and be difficult to clean, causing the first screw and the fixed plate to get stuck, which can easily affect the progress of the staff's concrete block testing work. In view of this, we propose a road and bridge concrete testing device. Utility Model Content

[0005] The embodiment of the present application solves the technical problems in the prior art and achieves the technical effects by providing a road bridge concrete detection device.

The sliders are slidably connected in the sliding grooves, so that the slip ring can only move horizontally in the fixed cylinder.

[0014] By adopting the above technical solution and setting a slider, the slide ring can drive the slide block to move in the slide groove when it moves in the fixed cylinder, so that the slide ring will not rotate in the fixed cylinder, and the slide ring can only move horizontally.

[0015] Optionally, a knob is fixedly connected to the other end of the connecting rod, a threaded tube is provided on the outer fixed sleeve of the connecting rod, a groove is opened on one side of the clamping plate, a first bearing is installed in the groove, a second bearing is installed in the slip ring, and the connecting rod is located on the inner side of the first bearing and the second bearing, thereby eliminating the need for staff to pull the connecting rod all the time.

[0016] By adopting the above technical solution, by setting a threaded tube and a threaded ring, after the staff pulls the connecting rod to drive the threaded tube to move to the position abutting the threaded ring, the staff can rotate the connecting rod to drive the threaded tube to rotate, so that the threaded tube is threadedly connected to the inner side of the threaded ring, so that the first spring remains in a squeezed state, preventing the first spring from rebounding, and thus there is no need for the staff to keep pulling the connecting rod.

[0017] Optionally, through holes are formed through the bottom of both sides of the box body, a sliding rod is fixedly connected to one side of the clamping plate, and the sliding rod is slidably connected to the through hole, thereby preventing the clamping plate from rotating.

A threaded ring 36 is fixedly connected to the other side of the fixed cylinder 32. The slip ring 34 is elastically connected to the threaded ring 36, so as to facilitate the clamping of concrete blocks and enable the staff to clean up the broken concrete chips.

[0032] Reference Figure 2 and Figure 3 A first spring 37 is fixedly connected to one side of the slip ring 34, one end of the first spring 37 is fixedly connected to the threaded ring 36, and the first spring 37 is sleeved on the outside of the connecting rod 33, so as to prevent the connecting rod 33 and the clamping plate 31 from moving at will.

[0033] Reference Figure 2 and Figure 3 Slide blocks 35 are fixedly connected on both sides of the slip ring 34, and sliding grooves for matching with the slide blocks 35 are opened on both sides of the inner wall of the fixed cylinder 32. The slide blocks 35 are slidably connected in the sliding grooves, so that the slip ring 34 can only move horizontally in the fixed cylinder 32.

[0034] Reference Figure 2 and Figure 3 The connecting rod 33 is rotatably connected to the slip ring 34 and the clamping plate 31. The size of the opening and the inner side of the threaded ring 36 are larger than the size of the two ends of the connecting rod 33, so that the connecting rod 33 can be rotated.

[0035] Reference Figure 3 A threaded tube 8 is fixedly sleeved on the outside of the connecting rod 33 , and the threaded tube 8 is located on the inside of the first spring 37 , so as to facilitate fixing the clamping plate 31 , thereby eliminating the need for the staff to pull the connecting rod 33 all the time.

[0036] Reference Figure 2 A groove is provided on one side of the splint 31, a first bearing 6 is installed in the groove, a second bearing 7 is installed in the slip ring 34, and the connecting rod 33 is located on the inner side of the first bearing 6 and the second bearing 7, so that the connecting rod 33 can rotate easily, and when the connecting rod 33 moves, it can drive the splint 31 and the slip ring 34 to move through the first bearing 6 and the second bearing 7 respectively.

[0037] Reference Figure 3 The other end of the connecting rod 33 is fixedly connected to a knob 10 , and an anti-slip pattern is provided on the outside of the knob 10 to facilitate the staff to rotate the connecting rod 33 .

[0038] Reference Figure 2 and Figure 3 The size of the knob 10 is larger than the size of the inner side of the threaded ring 36 , thereby preventing the end of the connecting rod 33 close to the knob 10 from entering the inner side of the fixing tube 32 .

[0041] Reference Figure 1 A handle is fixedly connected to one side of the box door 2 to facilitate the staff to open the box door 2.

[0042] The implementation principle of a road bridge concrete detection device in an embodiment of the present application is as follows: when the strength of a concrete block is detected, the hydraulic cylinder 4 can be started by an external controller to drive the detection pressure plate 5 to move downward to squeeze the concrete block. When the detection is completed, the staff can pull the connecting rod 33 to move. The movement of the connecting rod 33 can drive the slip ring 34 to move through the second bearing 7. The movement of the slip ring 34 can squeeze the first spring 37, and the movement of the connecting rod 33 can drive the threaded tube 8 and the clamping plate 31 to move. When the threaded tube 8 moves to abut against the threaded ring 36, the staff can rotate the connecting rod 33. The rotation of the connecting rod 33 can drive the threaded tube 8 to rotate, so that the threaded tube 8 is threadedly connected to the threaded ring 36, so that the first spring 37 remains in a squeezed state, and the connecting rod 33, the slip ring 34 and the clamping plate 31 will no longer move, which is convenient for the staff to clean up the broken concrete debris.

[0043] The embodiment of the present application provides a road bridge concrete detection device. By setting up a clamping mechanism 3, when a concrete block is broken, the broken concrete chips can remain on the inside of the box 1 without affecting the clamping mechanism 3, which is convenient for the staff to clean up, thereby ensuring that the progress of the staff's concrete block detection work is not affected.
