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.

[0024] Example:

[0025] See also Figure 1-5 A manipulator device for concrete test block test includes a manipulator body 1, a bottom block 2 is fixedly connected to the lower side of the manipulator body 1, the setting of the bottom block 2 enables the manipulator body 1 to be smoothly placed on the ground, and a gripping mechanism is provided on one side of the manipulator body 1. The manipulator body 1 can grip and clamp the concrete block through the gripping mechanism, and while gripping and clamping the concrete block, reduce the possibility of damage to the concrete block due to the small contact area with the concrete block.

[0026] The two movable blocks 35 are slidably connected to the outer sides of the two movable blocks 35, and the two movable blocks 35 are slidably connected to the outer sides of the two movable blocks 35. The mounting plate 31 is provided with a mounting groove 32 on one side of the manipulator body 1. The mounting plate 31 is fixedly connected with a mounting frame plate 9 on one side. The mounting plate 31 is provided with a mounting groove 32, and two mounting grooves 32 are provided. A bidirectional screw rod 33 and a limiting rod 34 are respectively provided on the inner sides of the two mounting grooves 32. The outer sides of the bidirectional screw rod 33 are threadedly connected with a moving block 35, and two moving blocks 35 are provided. The two moving blocks 35 are both slidably connected to the outer sides of the limiting rod 34. The mounting plate 31 can install and fix the bidirectional screw rod 33 and the limiting rod 34 through the mounting groove 32. The threads on both sides of the bidirectional screw rod 33 are opposite, and the limiting rod 34 can smoothly limit the two moving blocks 35. This makes it possible to smoothly drive the two moving blocks 35 to move in opposite directions when the bidirectional screw rod 33 is rotating. A first grabbing plate 36 and a second grabbing plate 37 are respectively fixedly connected on one side of the two moving blocks 35. When the two moving blocks 35 move, they will also smoothly drive the first grabbing plate 36 and the second grabbing plate 37. The first grab plate 36 and the second grab plate 37 move in opposite directions together, and when the first grab plate 36 and the second grab plate 37 move to a certain distance, the concrete block can be smoothly clamped and grabbed, which can not only realize the grabbing of the concrete block, but also can smoothly increase the contact area during grabbing and reduce the pressure. A servo motor 38 is fixedly connected to the inner side of the mounting frame plate 9, and the output shaft of the servo motor 38 passes through the mounting plate 31. The output shaft of the servo motor 38 is fixedly connected to the bidirectional screw 33 through a coupling. The mounting plate 31 can install the servo motor 38 through the mounting frame plate 9, and the operation of the servo motor 38 can smoothly drive the bidirectional screw 33 to rotate, thereby realizing the movement of the first grab plate 36 and the second grab plate 37. The servo motor 38 is electrically connected to the manipulator body 1, so that when the manipulator body 1 is in use, the servo motor 38 can also operate smoothly. The manipulator body 1 is a prior art in this field, so it will not be described in detail here.

[0027] Specifically, the upper side of the mounting plate 31 is fixedly connected with the first electric telescopic rod 41, the upper end of the first electric telescopic rod 41 is fixedly connected with the connecting plate 42, the lower side of the connecting plate 42 is fixedly connected with the second electric telescopic rod 43, the lower end of the second electric telescopic rod 43 is fixedly connected with the fixing plate 44, the first electric telescopic rod 41 can connect the second electric telescopic rod 43 through the connecting plate 42, and the second electric telescopic rod 43 can be connected to the fixing plate 44, the first electric telescopic rod 41 can smoothly adjust the position and height of the second electric telescopic rod 43 and the fixing plate 44 when telescoping, and the second electric telescopic rod The extension and retraction of 43 can further adjust the height of the fixed plate 44. After the grabbing mechanism grabs the concrete block, the manipulator body 1 can rotate the fixed plate 44 through its own operation, and make the fixed plate 44 smoothly cooperate with the first electric telescopic rod 41 and the second electric telescopic rod 43 to support and cushion the lower side of the concrete block, thereby increasing the stability of the concrete block when being grabbed. The first electric telescopic rod 41 and the second electric telescopic rod 43 are both electrically connected to the manipulator body 1, which enables the manipulator body 1 to smoothly start the first electric telescopic rod 41 and the second electric telescopic rod 43 during operation.

[0028] Specifically, a reinforcement ring block 6 is fixedly connected to the upper side of the mounting plate 31, and the reinforcement ring block 6 is fixedly connected to the outer side of the first electric telescopic rod 41. The reinforcement ring block 6 can increase the stability of the connection between the mounting plate 31 and the first electric telescopic rod 41, so that the first electric telescopic rod 41 can be sufficiently stable when in use and is not prone to falling, etc. A second rubber layer 52 is fixedly connected to one side of the first grabbing plate 36, and a first rubber layer 51 is fixedly connected to one side of the second grabbing plate 37. The first rubber layer 51 and the second rubber layer 52 can smoothly increase the friction between the first grabbing plate 36 and the second grabbing plate 37 and the concrete block, thereby further increasing the stability of the first grabbing plate 36 and the second grabbing plate 37 when clamping the concrete block.

[0029] Specifically, a fixing block 7 is fixedly connected to one side of the bottom block 2, and the fixing block 7 is used to increase the stability of the bottom block 2. The setting of the fixing block 7 makes the manipulator body 1 more stable when it is placed on the ground through the bottom block 2. A threaded groove 8 is opened on the upper side of the fixing block 7, and a plurality of threaded grooves 8 are provided. The setting of the threaded groove 8 makes it more convenient for the staff to connect the bottom block 2 and the fixing block 7 to the ground firmly by bolts when they need to.

[0030] The working principle and use process of the utility model: when the device is in use, the manipulator body 1 can move the first grabbing plate 36 and the second grabbing plate 37 to the outside of the concrete block through its own operation, and start the servo motor 38 after the movement. When the servo motor 38 is in operation, it will smoothly drive the bidirectional screw 33 to rotate. When the bidirectional screw 33 rotates, it will drive the first grabbing plate 36 and the second grabbing plate 37 to move in opposite directions through the opposite threads on both sides of itself and the limiting rod 34 on the first grabbing plate 36 and the second grabbing plate 37, so as to clamp and grab the concrete block. After that, the manipulator body 1 can also move the mounting plate 36 and the second grabbing plate 37 to the outside of the concrete block through its own operation. 1. The first electric telescopic rod 41 and the fixed plate 44 are rotated to rotate the fixed plate 44 to the lower side of the concrete block, and the fixed plate 44 is moved to the lower side of the concrete block through the operation of the first electric telescopic rod 41 and the second electric telescopic rod 43 to support and lift the concrete block. After that, the manipulator body 1 can smoothly move the concrete block to the equipment to be inspected. This can solve the problem that most existing manipulators use a three-claw or four-claw grasping method when in use. This makes the force-bearing area of ​​the concrete block smaller and the pressure it is subjected to greater when the manipulator grasps the concrete block, which may affect the subsequent detection of the concrete block.

[0031] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
