[0002] The impact strength of building concrete materials is an important indicator to measure their toughness. It is of great significance to ensure the structural integrity and safety of buildings. During the construction process, prefabricated or cast concrete materials need to be regularly tested for impact strength to evaluate the impact strength of concrete materials. When testing the impact strength of concrete materials, it is usually necessary to use professional testing tools to perform impact tests on the prepared concrete materials.

[0034] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1 - Figure 7, a tool for testing the impact strength of building concrete materials, comprising: a mounting frame 1; a mounting platform 2 is installed on the inner side of one end of the mounting frame 1, four rollers 6 are arranged at the bottom of the mounting frame 1, and a push handle 5 is installed at the other end of the mounting frame 1. The staff can push the mounting frame 1 through the push handle 5. The staff puts the materials to be tested on the ground according to the corresponding placement size in advance. The end of the mounting frame 1 on which the mounting platform 2 is installed has a certain space at the bottom of the mounting platform 2 because the mounting position of the mounting platform 2 is higher. The staff aligns the mounting platform 2 above the material and pushes the mounting frame 1 to the top of the material. After the position of the mounting frame 1 is confirmed, the rollers 6 are set to be lockable. After locking the four rollers 6, the position of the mounting frame 1 is fixed;The impact device 3 is used to perform an impact test on the material. The impact device 3 is arranged on the mounting frame 1. The impact device 3 includes a double-headed motor 31, which is installed on the mounting table 2. Reciprocating screw rods 34 are rotatably installed on the outer walls of both sides of the mounting frame 1. One end of the reciprocating screw rod 34 close to the double-headed motor 31 is connected to a second bevel gear rod 33. The two output ends of the double-headed motor 31 are respectively connected to two first bevel gear rods 32. The two first bevel gear rods 32 are both rotatably installed on the mounting frame 1 through a bracket. The two first bevel gear rods 32 are respectively meshed with the two second bevel gear rods 33. Ball sliders 35 are respectively slidably installed on the outer walls of both sides of the mounting frame 1. A reciprocating thread groove is provided on the reciprocating screw rod 34. The inner walls of the two ball sliders 35 are respectively connected to the two reciprocating screw rods 34 through balls. The reciprocating thread groove of the screw rod 34 is slidably connected. When the reciprocating screw rod 34 rotates, the cooperation between the reciprocating thread groove and the ball drives the ball slider 35 to move back and forth left and right. The two reciprocating screw rods 34 respectively drive the two ball sliders 35 to move back and forth left and right synchronously. Sliding shafts 36 are respectively installed on the two ball sliders 35. Mounting shafts 37 are slidably installed on the two sliding shafts 36. The outer wall of the mounting shaft 37 is connected to a mounting seat 38. The bottom of the mounting seat 38 penetrates and is slidably connected with an impact cone 39. The bottom of the mounting seat 38 is connected to a spring seat 310. The impact cone 39 penetrates the spring seat 310. A spring is arranged in the spring seat 310. The spring in the spring seat 310 is connected to the impact cone 39. Mounting grooves are respectively arranged inside the two sides of the mounting frame 1. The serrated plates 313 are slidably installed in the two installation grooves, and the serrated plates 313 are provided with multiple climbing surfaces. The installation shaft 37 contacts the multiple climbing surfaces of the two serrated plates 313 in turn during the movement. The installation shaft 37 contacts the climbing surfaces on the two serrated plates 313 in the process of moving to the left and climbs upward along the two climbing surfaces. When the installation shaft 37 is not in contact with the two climbing surfaces, the installation shaft 37 falls due to its own gravity, and the mounting seat 38 drives the impact cone 39 to fall together. During the falling process, the impact cone 39 impacts the surface of the material, so that an impact hole is formed on the surface of the material. The elastic force of the spring in the spring seat 310 is relatively large, and the rebound amplitude of the impact cone 39 can reflect the impact strength of the material. In the process of moving to the left, the installation shaft 37 uses the above principle to contact the multiple climbing surfaces in turn. The impact test can be performed on multiple materials at the same time without moving the materials. When testing a larger material, the staff pushes the mounting frame 1 to the top of the larger material, and performs impact tests on multiple points on the surface of the larger material in the same manner as above. The accuracy of the test results can be improved by testing multiple points. A slide bar 311 is installed on the top of the mounting seat 38, and a plurality of counterweights 312 are sleeved on the slide bar 311. A knob is provided on the slide bar 311. After the knob is turned down, the counterweights 312 can be added or reduced. By assembling different numbers of counterweights 312, the weight of the mounting seat 38 can be adjusted to adjust the impact force of the mounting seat 38 falling, thereby achieving the effect of adjusting the impact strength.The bottom of the sawtooth plate 313 is connected to two No. 1 inclined panels 314, and two No. 2 inclined panels 315 are slidably installed in the mounting groove of the mounting frame 1. The two No. 1 inclined panels 314 are respectively in contact with the two No. 2 inclined panels 315, and two connecting rods 316 are connected between the two No. 2 inclined panels 315. The No. 1 inclined panel 315 close to the mounting platform 2 is connected to a No. 1 lever 317, and the No. 2 inclined panel 315 close to the push handle 5 is connected to a No. 2 lever 318. The bottom of the ball slider 35 is connected to a push rod 319. The two No. 2 inclined panels 315 After moving to the left, the inclined surfaces of the two No. 1 inclined panels 314 slide along the inclined surfaces of the two No. 2 inclined panels 315, and the two No. 2 inclined panels 315 gradually lose their supporting force on the two No. 1 inclined panels 314, causing the two No. 1 inclined panels 314 and the serrated plate 313 to slide down by their own gravity, and the serrated plate 313 shrinks into the installation groove after sliding down. After the two serrated plates 313 shrink into the installation groove, they no longer block the movement trajectory of the installation shaft 37, and the two No. 2 inclined panels 315 and the connecting rod 316 move to the right, and the inclined surfaces of the two No. 2 inclined panels 315 connect the two The inclined surface of the first inclined panel 314 is lifted upward, so that the sawtooth plate 313 moves upward, and finally the two second inclined panels 315 move to the bottom of the two first inclined panels 314 for support, so that the sawtooth plate 313 is reset upward, achieving the effect of automatic reset; through the setting of the impact device 3, the mounting frame 1 can be pushed above the concrete material to be tested, and the impact cone 39 performs impact tests on multiple concrete materials in sequence by gravity drop, which reduces the operation steps of the staff to carry the concrete materials, reduces the labor intensity of the staff, and tests multiple concrete materials at one time, improves the test efficiency. When testing larger concrete materials, the accuracy of the test results is improved by testing multiple points; through the cooperation of the four first inclined panels 314 and the four second inclined panels 315, the two sawtooth plates 313 can automatically retract into the mounting frame 1 after the test, which is convenient for the reset of the mounting shaft 37. After the reset of the mounting shaft 37, the two sawtooth plates 313 automatically rise, achieving the effect of automatic reset, and further improving the convenience of operation. ;

[0037] For further information, see Figure 8 - Fig.13The recording device 4 is used to record the impact resistance of the material. The recording device 4 is arranged on the impact device 3. The recording device 4 includes a drawing pen 41. The drawing pen 41 is installed on the top of the impact cone 39 through a bracket. A winding drum 42 is installed on the outer wall of the mounting seat 38. A through groove is arranged on the mounting seat 38. A drawing paper 43 is wound inside the winding drum 42. One end of the drawing paper 43 away from the winding drum 42 passes through the through groove of the mounting seat 38. The drawing pen 41 contacts the drawing paper 43. The winding drum 42 contains a rolled drawing paper 43. The staff passes one end of the drawing paper 43 through the through groove of the mounting seat 38 in advance, so that one end of the drawing paper 43 is clamped between the cushion block 44 and the friction roller 45. When the impact cone 39 contracts, the impact cone 39 drives the drawing pen 41 to move up and down, and the drawing pen 41 draws a line segment on the drawing paper 43. The higher the line segment, the greater the rebound amplitude of the impact cone 39, and the stronger the impact resistance of the material. The lower the line segment, the smaller the rebound amplitude of the impact cone 39, and the weaker the impact resistance of the material. A scale is set on the drawing paper 43. The scales of different heights represent different impact resistances, which is convenient for the staff to refer to. The outer wall of the mounting seat 38 is rotatably mounted with a friction roller 45, and the outer wall of the mounting seat 38 is mounted with a cushion block 44. A part of the drawing paper 43 is located between the cushion block 44 and the friction roller 45, and the friction roller 45 and the cushion block 44 are both connected to the drawing paper 43. The bottom of the friction roller 45 is connected with a worm gear 46, and a worm 47 is rotatably installed on the outer wall of the mounting seat 38. The worm gear 46 meshes with the worm 47. The outer wall of the mounting seat 38 is connected with a rotating frame 48, and a rotating shaft 49 is rotatably installed on the rotating frame 48. Both ends of the rotating shaft 49 are respectively connected with driven wheels 410. The inner walls of both sides of the mounting frame 1 are connected with multiple friction strips 411, and the multiple friction strips 411 are respectively located below the multiple climbing surfaces on the two serrated plates 313. The length of the friction strips 411 is less than the length of the climbing surface of the serrated plates 313. There is a friction strip 411 at the bottom of each climbing surface, and the two driven wheels 410 contact two of the friction strips 411 during the movement. There is a large friction force between the friction strip 411 and the driven wheel 410, so that the driven wheel 410 can rotate when moving on the friction strip 411. A belt 412 is sleeved between the rotating shaft 49 and the worm 47. When the rotating shaft 49 rotates, the worm 47 is driven to rotate through the belt 412. When the worm 47 rotates, the friction roller 45 is driven to rotate through the worm wheel 46. There is a large friction force between the friction roller 45 and the drawing paper 43, so that the friction roller 45 can drive the drawing paper 43 to move outward by rotating, achieving the effect of automatically pulling out the drawing paper 43. After each material test, the drawing paper 43 will be pulled outward for a distance, so that the line segments of different materials are evenly separated for easy observation;A rebound slider 413 is slidably installed on the outer wall of the mounting seat 38, and a cutter 414 is connected to the rebound slider 413. A return spring is arranged on the rebound slider 413. The cutter 414 contacts the drawing paper 43 during movement. A resistance rod 415 is installed on the mounting table 2. The rebound slider 413 contacts the resistance rod 415 during movement. A recovery box 416 is installed on the mounting table 2. The resistance rod 415 can resist the moving rebound slider 413, so that the cutter 414 can press the drawing paper 43 against the cushion block 44, and cut the drawing paper 43 by pressure. The cut drawing paper 43 falls into the recovery box 416, and the staff can directly take it out of the recovery box 416. The drawing paper 43 is observed, which further improves the convenience of operation. After the mounting seat 38 turns to move to the right, the rebound slider 413 is separated from the contact with the resistance rod 415 and reset by the spring elastic force, and the cutter 414 is reset accordingly; through the setting of the recording device 4, the drawing pen 41 can convert the impact strength of each concrete material into a line segment and draw it on the drawing paper 43, and the line segments corresponding to multiple concrete materials are evenly separated, which is convenient for the staff to observe; through the setting of the cutter 414, after the batch of concrete materials completes the impact test, the cutter 414 can cut the drawing paper 43, which is convenient for the staff to take the drawing paper 43, further improving the convenience of operation. ;

[0038] With the above structure, the working principle of this case is that since four rollers 6 are arranged at the bottom of the mounting frame 1, the staff can push the mounting frame 1 through the push handle 5. The staff puts the materials to be tested on the ground in advance according to the corresponding placement size. One end of the mounting frame 1 is equipped with the mounting table 2. Since the mounting position of the mounting table 2 is higher, a certain space is left at the bottom of the mounting table 2. The staff aligns the mounting table 2 with the top of the material and pushes the mounting frame 1 to the top of the material. When testing multiple smaller materials, multiple smaller materials are placed in a row, and the distance between adjacent materials is equal to the distance between adjacent climbing surfaces on the sawtooth plate 313. The sawtooth plate 313 can be regarded as multiple right triangles. The climbing surface of the sawtooth plate 313 is the hypotenuse of the right triangle, and the right-angled sides of the multiple right triangles are respectively located above the multiple materials. After the position of the mounting frame 1 is confirmed, the roller 6 is set to be lockable. After locking the four rollers 6, the position of the mounting frame 1 is fixed;Start the double-headed motor 31, the double-headed motor 31 drives the two No. 1 bevel gear rods 32 to rotate, the two No. 1 bevel gear rods 32 respectively drive the two No. 2 bevel gear rods 33 to rotate, the two No. 2 bevel gear rods 33 respectively drive the two reciprocating screw rods 34 to rotate, when the reciprocating screw rods 34 rotate, the cooperation of the reciprocating thread groove and the ball drives the ball slider 35 to move back and forth left and right, the two reciprocating screw rods 34 respectively drive the two ball sliders 35 to move back and forth left and right synchronously, the initial position of the two ball sliders 35 is located on the right side of the mounting frame 1, the two ball sliders 35 start to move to the left first, and when the two ball sliders 35 move, they are driven by the two sliding shafts 36 The movable mounting shaft 37 moves to the left, the mounting shaft 37 drives the mounting seat 38 to move to the left, and the impact cone 39 moves synchronously with the mounting seat 38. The mounting shaft 37 contacts the climbing surfaces on the two serrated plates 313 during the movement to the left and climbs upward along the two climbing surfaces. When the mounting shaft 37 is not in contact with the two climbing surfaces, the mounting shaft 37 falls by its own gravity, and the mounting seat 38 drives the impact cone 39 to fall together. During the falling process, the impact cone 39 impacts the surface of the material, so that an impact hole is formed on the surface of the material. Then the mounting shaft 37 contacts the two climbing surfaces again and climbs upward, and the impact cone 39 moves upward until it is out of contact with the material. The elastic force of the spring in the spring seat 310 is relatively large. When the impact resistance of the material is relatively strong, the impact cone 39 cannot penetrate into the surface of the material, so that the impact cone 39 squeezes the spring and shrinks into the mounting seat 38. After the impact cone 39 moves upward, it is reset by the elastic force of the spring. The rebound amplitude of the impact cone 39 is relatively large. When the impact resistance of the material is relatively poor, the impact cone 39 directly penetrates into the material to form a deeper impact hole. The rebound amplitude of the impact cone 39 is relatively small. Therefore, the rebound amplitude of the impact cone 39 can reflect the impact resistance of the material. The mounting shaft 37 uses the above principle in the process of moving to the left to impact multiple materials in turn. The test achieves the effect of being able to perform impact tests on multiple materials at the same time without moving the materials. When testing a larger material, the staff pushes the mounting frame 1 above the larger material, and performs impact tests on multiple points on the surface of the larger material in the same manner as the above operation. By testing multiple points, the accuracy of the test results can be improved. A knob is provided on the slide bar 311. After the knob is turned down, the counterweight block 312 can be added or reduced. By assembling different numbers of counterweight blocks 312, the weight of the mounting seat 38 can be adjusted to adjust the impact force of the mounting seat 38 falling, thereby achieving the effect of adjusting the impact strength.After the last material test is completed, the two ball sliders 35 continue to move to the left, and the movement of the ball sliders 35 drives the push rods 319 to move synchronously. During the movement of the two push rods 319 to the left, they contact the two No. 1 levers 317 and push the two No. 1 levers 317 to the left. Since the No. 1 lever 317, the two No. 2 inclined panels 315, the connecting rod 316 and the No. 2 lever 318 in the same mounting groove of the mounting frame 1 are connected together, when the No. 1 lever 317 moves to the left, the two No. 2 inclined panels 315, the connecting rod 316 and the No. 2 lever 318 move to the left together. Since the mounting groove limits the serrated plate 313, the serrated plate 313 can only move up and down, and the two No. 2 inclined panels 315 After moving to the left, the inclined surfaces of the two No. 1 inclined panels 314 slide along the inclined surfaces of the two No. 2 inclined panels 315, and the two No. 2 inclined panels 315 gradually lose their supporting force on the two No. 1 inclined panels 314, causing the two No. 1 inclined panels 314 and the serrated plate 313 to slide down by their own gravity. After the serrated plate 313 slides down, it shrinks into the installation groove. After the two serrated plates 313 shrink into the installation groove, they no longer block the movement trajectory of the installation shaft 37. Subsequently, the two ball sliders 35 turn to move right, and the installation shaft 37 does not contact the two serrated plates 313 during the rightward movement. When the installation shaft 37 moves to the right side of the two serrated plates 313, the two push rods 319 contact the two No. 2 levers 318 and move the No. 2 levers 318 to the left. The rod 318 is pushed to the right, and the second lever 318 drives the first lever 317, the two second inclined panels 315 and the connecting rod 316 to move to the right. The inclined surfaces of the two second inclined panels 315 push up the inclined surfaces of the two first inclined panels 314, so that the serrated plate 313 moves upward. Finally, the two second inclined panels 315 move to the bottom of the two first inclined panels 314 for support, so that the serrated plate 313 is reset upward. At this time, the double-headed motor 31 stops rotating, and the two serrated plates 313 and the mounting shaft 37 return to their initial positions, achieving the effect of automatic reset. By setting the impact device 3, the mounting frame 1 can be pushed above the concrete material to be detected, and the impact cone 39 is pushed down by gravity. The impact test is performed on multiple concrete materials in sequence in a falling manner, which reduces the operation steps of the workers in carrying concrete materials, reduces the labor intensity of the workers, and tests multiple concrete materials at one time, which improves the test efficiency. When testing larger concrete materials, the accuracy of the test results is improved by testing multiple points; through the cooperation of the four No. 1 inclined panels 314 and the four No. 2 inclined panels 315, the two sawtooth plates 313 can automatically retract into the mounting frame 1 after the test is completed, which is convenient for the installation shaft 37 to reset. After the installation shaft 37 is reset, the two sawtooth plates 313 automatically rise, achieving the effect of automatic reset, and further improving the convenience of operation. ;

[0039] The winding drum 42 contains a rolled drawing paper 43. The staff passes one end of the drawing paper 43 through the through slot of the mounting seat 38 in advance, so that one end of the drawing paper 43 is clamped between the cushion block 44 and the friction roller 45, and calibrates the position of the drawing pen 41 so that the drawing pen 41 contacts the drawing paper 43. When the impact cone 39 contracts, the impact cone 39 drives the drawing pen 41 to move up and down, and the drawing pen 41 draws a line segment on the drawing paper 43. The higher the line segment, the greater the rebound amplitude of the impact cone 39, and the stronger the impact strength of the material. The lower the line segment, the smaller the rebound amplitude of the impact cone 39, and the weaker the impact strength of the material. There are scales on the drawing paper 43, and scales of different heights represent different impact strengths. degrees, for the convenience of staff reference, since the length of the friction strip 411 is less than the length of the climbing surface of the sawtooth plate 313, there is a friction strip 411 at the bottom of each climbing surface, and when the mounting shaft 37 contacts the climbing surface and starts to move upward, the driven wheels 410 at both ends of the rotating shaft 49 contact the two friction strips 411. Since there is a large friction force between the friction strips 411 and the driven wheels 410, the driven wheels 410 can rotate when moving on the friction strips 411, and the two driven wheels 410 drive the rotating shaft 49 to rotate on the rotating frame 48. When the rotating shaft 49 rotates, it drives the worm 47 to rotate through the belt 412. When the worm 47 rotates, it drives the friction roller 45 to rotate through the worm wheel 46. The friction roller 45 and the drawing There is a large friction between the paper 43, so that the friction roller 45 can drive the drawing paper 43 to move outward by rotating, so as to achieve the effect of automatically pulling out the drawing paper 43. When the drawing pen 41 moves up and down, the drawing paper 43 does not move. When the drawing pen 41 stops moving up and down until the next up and down movement, the two driven wheels 410 contact two of the friction strips 411 and rotate, and the drawing paper 43 is pulled outward for a distance to avoid being covered by drawing marks and inconvenient to observe. After each material test is completed, the drawing paper 43 will be pulled outward for a distance to evenly separate the line segments of different materials for easy observation. When the last material is tested, the mounting seat 38 continues to move to the left, and the rebound slider 413 contacts the resistance rod 415, so that the rebound slider 413 is subjected to the reverse thrust of the resistance rod 415 and stops moving to the left. At this time, the cushion block 44 and the drawing paper 43 continue to move to the left. When the drawing paper 43 moves to the left, it contacts the cutter 414 on the rebound slider 413, so that the cutter 414 presses the drawing paper 43 against the cushion block 44, and cuts the drawing paper 43 by pressure. The cut drawing paper 43 falls into the recycling box 416, and the staff can directly take the drawing paper 43 in the recycling box 416 for observation, which further improves the convenience of operation. After the mounting seat 38 turns to move to the right, the rebound slider 413 is separated from the contact with the resistance rod 415 and resets by the spring elastic force, and the cutter 414 is reset accordingly;By setting the recording device 4, the drawing pen 41 can convert the impact strength of each concrete material into a line segment and draw it on the drawing paper 43, and the line segments corresponding to multiple concrete materials are evenly separated, which is convenient for staff to observe; by setting the cutter 414, after the batch of concrete materials completes the impact test, the cutter 414 can cut the drawing paper 43, which is convenient for staff to take the drawing paper 43, further improving the convenience of operation. ;
