DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In order to solve the technical problem that the fixing and replacement actions of the detection head are relatively frequent and the efficiency needs to be improved, the utility model provides a concrete strength detection device, which can improve the working efficiency.

[0026] It should be noted that the concrete strength detection device described in the utility model is used for but not limited to concrete strength detection, etc. For the convenience of explanation, in the utility model, only a concrete strength detection device applied to concrete strength detection equipment is used as an example for explanation. The principle of applying a concrete strength detection device to other types of equipment is essentially the same as the principle applied to concrete detection equipment, which will not be repeated here.

[0027] See also Figure 1 - Figure 3 , Figure 1 This is a structural schematic diagram of a concrete strength detection device in an embodiment of the utility model, a concrete strength detection device includes a workbench 100, an arc turntable 200, a servo motor 300 and a stamping mechanism 400; the arc turntable 200 is arranged on the workbench 100, and a placement surface 210 is provided on the arc turntable 200; the servo motor 300 is used to drive the arc turntable 200 to rotate; the stamping mechanism 400 is arranged above the arc turntable 200, the stamping mechanism 400 includes a stamping rod 410, a first detection head 420, a second detection head 430 and a cylinder 440, the cylinder 440 is used to drive the stamping rod 410 to move up and down, the first detection head 420 and the second detection head 430 are respectively arranged on both sides of the bottom end of the stamping rod 410, and the stamping rod 410 and the arc turntable 200 are coaxially arranged.

[0028] In this embodiment, by setting up an arc turntable 200 and using a servo motor 300 to drive the arc turntable 200 to rotate, a structural foundation for a rotating transformation detection head is constructed; specifically, a first detection head 420 and a second detection head 430 are respectively provided on both sides of the bottom end of the punch rod 410, so that when the cylinder 440 drives the punch rod 410 to move downward, for example, the first detection head 420 or the second detection head 430 can abut against the concrete on the workbench 100 and complete the strength test; and when the detection head needs to be adjusted, the servo motor 300 needs to be used to rotate the arc turntable 200 180 degrees, and the second detection head 430 or the first detection head 420 can be used for strength testing, without the need to replace the detection head through multiple steps, which effectively improves work efficiency. It should be pointed out that when the concrete is placed on the workbench 100, it can be determined whether to use a clamp block for fixed clamping according to the size and weight of the concrete, and it is not necessary to limit it completely.

[0029] In one embodiment, see Figure 2-Figure 5 The punching rod 410 includes a vertical rod 411 and a bottom plate 412 . A plurality of positioning holes 413 are formed at the bottom end of the bottom plate 412 . The positioning holes 413 are detachably connected to the first detection head 420 and the second detection head 430 .

[0030] In this embodiment, the first detection head 420 and the second detection head 430 are detachably connected, which is convenient for timely and convenient replacement. It should be noted that the specifications and sensitivity of the first detection head 420 and the second detection head 430 are adjusted according to detection needs.

[0031] In one embodiment, see Figure 1 - Figure 5 The positioning holes 413 are symmetrically distributed along the bottom end of the bottom plate 412 .

[0032] In this embodiment, the symmetrical distribution of the bottom plate 412 enables both the first detection head 420 and the second detection head 430 to perform effective detection after the arc-shaped turntable 200 rotates.

[0033] In one embodiment, see Figure 1 The stamping mechanism 400 also includes a support frame 450 , a cylinder 440 is disposed on one side of the top of the support frame 450 , a stamping rod 410 is disposed on one side of the support frame 450 away from the cylinder 440 , and the support frame 450 is installed on the workbench 100 .

[0034] In this embodiment, the support frame 450 helps to fix and expand the cylinder 440.

[0035] In one embodiment, see Figure 1 , the arc of the arc turntable 200 is 180°

[0036] In this embodiment, the arc design of the arc-shaped turntable 200 can maximize the placement of concrete.

[0037] In one embodiment, see Figure 1 , Figure 4 The servo motor 300 is disposed at the bottom of the workbench 100, and the output end of the servo motor 300 extends into the workbench 100 and is transmission-connected to the arc-shaped turntable 200.

[0038] In this embodiment, the servo motor 300 is placed at the bottom of the workbench 100, which is not only more reasonable but also convenient for maintenance.

[0039] In one embodiment, see Figure 1 The top end opening of the workbench 100 is provided with a chamfer 110

[0040] In this embodiment, the chamfer 110 can allow a small amount of splashed concrete to slide down into the workbench 100 .

[0041] In one embodiment, see Figure 1 The top of the workbench 100 has a cavity 120 with an opening facing upward, and the cavity 120 is used to place the arc-shaped turntable 200.

[0042] In this embodiment, the structure of the cavity 120 allows the arc-shaped turntable 200 to rotate more smoothly, and allows the concrete blocks to be collected in the cavity 120 without splashing.

[0043] In one embodiment, see Figure 1 A discharge groove 130 is provided at one side of the bottom of the cavity 120 .

[0044] In this embodiment, the discharge chute 130 allows the concrete blocks to be discharged from a single outlet. Preferably, a slide door that can be opened and closed can also be provided at the discharge chute 130 for easy control.

[0045] In one embodiment, see Figure 1 The notch of the discharge trough 130 is rectangular.

[0046] In this embodiment, the opening design of the discharge chute 130 allows the concrete blocks to be discharged more quickly.

[0047] In order to better understand the present invention, the following Figures 1 to 5 The technical solution of the utility model is described in detail:

[0048] When the concrete strength detection device in the utility model is used, first, the first detection head 420 and the second detection head 430 are inserted into the corresponding positioning holes 413; then, the concrete is placed on the storage surface 210; then, the cylinder 440 is started and the bottom plate 412 is driven to move downward, so that the first detection head 420 or the second detection head 430 abuts against the concrete block and completes the strength detection; when the detection head needs to be replaced, it is only necessary to start the servo motor 300 and drive the arc turntable 200 to rotate 180 degrees, and start the cylinder 440 again; at this time, the second detection head 430 or the first detection head 420 completes the strength detection. Since the above detection work does not require the replacement of the detection head in a number of steps, the work efficiency can be effectively improved. It should be emphasized that the first detection head 420 and the second detection head 430 are installed before the formal work, and are only simply snap-fitted or snap-fitted and then fixed with pins, which is more convenient.

[0049] The above specific implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
