Description

Technical Field

[0001] The utility model relates to the technical field of dam strength detection, in particular to a dam strength detector. Background Art

[0002] Patent No. CN202321863483.9 discloses a dam strength tester. The utility model can adjust the angle of the tester during use to adapt to dams with different slopes, thereby increasing the scope of use.

[0003] However, the applicant discovered that after adjusting the angle, the first electric push rod is required to drive the detector body to move, and then insert the drill bit of the detector body into the dam and perform a strength test. Therefore, when the drill bit is driven to insert into the dam, the structure used to adjust the angle is always under stress, which may easily lead to a decrease in service life over time. Moreover, once maintenance is required, the angle of the detector body can no longer be adjusted, resulting in limited use. For this reason, we propose a dam strength detector. Utility Model Content

[0006] Support plates are provided on the front and rear sides of the mounting plate, rotating shafts are provided on the support plates on both sides, a bidirectional screw rod is provided between the rotating shafts on both sides, clamping plates are screwed on both sides of the bidirectional screw rod, a hand wheel is provided at the front end of the front rotating shaft, sliders slidably connected to the mounting plates are provided at the bottom of the clamping plates on both sides, anti-slip pads are provided on the opposite sides of the clamping plates on both sides, and the anti-slip pads on both sides are respectively in contact with the front and rear sides of the fixing plate.

[0007] As a preferred solution of the dam strength detector described in the utility model, a connecting rod is arranged on the mounting plate, and a distance sensor located at the front side of the front clamping plate is arranged on the connecting rod.

[0008] As a preferred solution of the dam strength detector described in the utility model, a control box is arranged on the base, and the control box is electrically connected to the distance sensor.

[0009] As a preferred solution of the dam strength detector described in the utility model, an electric telescopic rod is arranged on the top of the fixed plate, and a stopper located on the right side of the detector body is arranged at the output end of the electric telescopic rod.

[0010] As a preferred solution of the dam strength detector described in the utility model, wherein: the electric telescopic rod is electrically connected to the control box.

[0011] As a preferred solution of the dam strength detector described in the utility model, a buffer pad in contact with the detector body is arranged on the left side of the stopper.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By rotating the hand wheel, the rotating shaft drives the bidirectional screw to rotate, and then drives the clamping plates on both sides to move toward the opposite side, fix the fixed plate with the adjusted angle, and then when the electric push rod drives the drill bit on the detector body to insert into the dam, the pressure can be shared by the clamping plate to avoid only the angle adjustment component being stressed, thereby increasing the service life of the angle adjustment component. Moreover, when the angle adjustment component needs to be repaired, the clamping plate can be used to ensure the detection work;

[0014] 2. When the drill bit on the detector body is pushed out by the electric push rod, it will be blocked by the buffer pad on the block. Therefore, it is necessary to first move the fixing plate toward the opposite side by the clamping plates on both sides. When the distance sensor detects that the front clamping plate moves backward to the required distance, the control box can be used to control the block on the electric telescopic rod to move downward and no longer block the detector body. Therefore, it can be ensured that the clamping plate needs to fix the fixing plate when using the detector body to avoid omission by the inspector, thereby improving the stability during the inspection process; after the inspection, the detector body and the drill bit are retracted. When the angle needs to be adjusted, the clamping plate needs to be loosened, and then the electric telescopic rod can drive the block to move upward again to block the detector body again.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As mentioned in the background technology, when the drill bit is driven to insert into the dam in the prior art, the structure used to adjust the angle is always under stress, which may easily lead to a decrease in service life in the long run. Moreover, once maintenance is required, the angle of the detector body can no longer be adjusted, resulting in limited use.

[0021] The utility model provides a dam strength detector.

[0022] Example 1

[0023] Reference Figures 1 to 3 A dam strength detector comprises a base 1, a forward and backward moving component 2 is arranged on the base 1, a lifting component 3 is arranged on the forward and backward moving component 2, a mounting plate 4 is arranged on the lifting component 3, an angle adjustment component 5 is arranged on the mounting plate 4, a fixing plate 6 is connected to the angle adjustment component 5, and the fixing plate 6 is rotatably connected to the mounting plate 4, an electric push rod 7 is arranged on the fixing plate 6, and a detector body 8 is arranged on the electric push rod 7, the forward and backward moving component 2 is used to adjust the forward and backward position, the lifting component 3 is used to adjust the height, the angle adjustment component 5 adjusts the angle between the fixing plate 6 and the detector body 8, and the electric push rod 7 is used to drive the detector body 8 to move so that the drill bit enters the dam. This is the prior art used to detect the dam strength in patent number CN202321863483.9;

[0024] Support plates 9 are provided on the front and rear sides of the mounting plate 4, and rotating shafts are provided on the support plates 9 on both sides. A bidirectional screw is provided between the rotating shafts on both sides, and clamping plates 11 are screwed on both sides of the bidirectional screw. A hand wheel 10 is provided at the front end of the front rotating shaft. In order to guide the clamping plates 11, sliders 12 slidably connected to the mounting plate 4 are provided at the bottom of the clamping plates 11 on both sides. In order to improve the clamping effect of the fixed plate 6, anti-slip pads 13 are provided on the opposite sides of the clamping plates 11 on both sides, and the anti-slip pads 13 on both sides are respectively in contact with the front and rear sides of the fixed plate 6.

[0025] By rotating the handwheel 10, the rotating shaft drives the bidirectional screw to rotate, and then drives the clamping plates 11 on both sides to move toward the opposite sides, fixing the fixed plate 6 with the adjusted angle, and then the electric push rod 7 drives the drill bit on the detector body 8 to insert into the dam. The pressure can be shared by the clamping plate 11 to avoid that only the angle adjustment component 5 is subjected to force, thereby increasing the service life of the angle adjustment component 5, and when the angle adjustment component 5 needs to be repaired, the clamping plate 11 can be used to ensure the detection work.

[0026] A connecting rod 14 is disposed on the mounting plate 4 , and a distance sensor 15 is disposed on the connecting rod 14 and is located in front of the front clamping plate 11 , so as to detect the distance between the connecting rod 14 and the front clamping plate 11 .

[0027] A control box 19 is disposed on the base 1 , and the control box 19 is electrically connected to the distance sensor 15 , and the distance sensor 15 transmits a detection signal to the control box 19 .

[0028] An electric telescopic rod 16 is arranged on the top of the fixing plate 6 , and a stopper 17 located on the right side of the detector body 8 is arranged at the output end of the electric telescopic rod 16 , and the stopper 17 is used to stop the detector body 8 from extending.

[0029] The electric telescopic rod 16 is electrically connected to a control box 19 , and the control box 19 is used to control the electric telescopic rod 16 .

[0030] Example 2

[0031] Reference Figures 1 to 3 In order to prevent the detector body 8 from being squeezed and damaged when it is extended, a buffer pad 18 in contact with the detector body 8 is provided on the left side of the stopper 17.

[0032] The rest of the structure is the same as that of Example 1.

[0033] When the drill bit on the detector body 8 is pushed out by the electric push rod 7, it will be blocked by the buffer pad 18 on the stopper 17. Therefore, it is necessary to first move the fixing plate 6 toward the opposite side through the clamping plates 11 on both sides. At this time, when the distance sensor 15 detects that the front clamping plate 11 moves backward to the required distance, the stopper 17 on the electric telescopic rod 16 can be controlled to move downward and no longer block the detector body 8 under the processing of the control box 19. Therefore, it can be ensured that when the detector body 8 is used, the clamping plate 11 needs to fix the fixing plate 6 first to avoid omission by the detection personnel, thereby improving the stability during the detection process; after the detection is completed, the detector body 8 and the drill bit are retracted. When the angle needs to be adjusted, the clamping plate 11 needs to be loosened first. Then, after the distance sensor 15 detects that the distance becomes smaller, the electric telescopic rod 16 can be controlled again through the control box 19 to drive the stopper 17 to move upward again to block the detector body 8 again.
