Technical Field
[0001] The utility model belongs to the technical field of weight hammers, in particular to a low-strain controllable weight hammer. Background Art
[0002] The low-strain controllable weight hammer is a construction inspection tool, specifically a tool for inspecting the integrity of pile bodies.
[0003] During the use of the low-strain controllable weight hammer, the pile body needs to be continuously struck. The vibration data generated by the striking will be transmitted to the display screen connected to the hammer body. At this time, the vibration signals can be observed to determine whether the pile body is complete or has defects.
[0004] The existing low-strain controllable weight hammer usually needs to continuously strike the pile during use. When the pile is struck repeatedly, if the striking force and angle deviate, the obtained data will also deviate accordingly, thereby affecting the accuracy of the data.
[0005] To this end, the utility model provides a low-strain method controllable weight hammer. Utility Model Content
[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.
[0007] The technical solution adopted by the utility model to solve its technical problems is: a low-strain controllable weight hammer described in the utility model comprises a support plate; two groups of support rods are fixedly connected to the bottom of the support plate; the two groups of support rods are located at the four corners of the bottom of the support plate, and are arranged opposite to each other in pairs; a through hole is opened at the bottom of the support plate, and the through hole is located in the middle of the bottom of the support plate; a rotating rod is fixedly connected to the inside of the through hole; a threaded barrel is rotatably connected to the middle of the rotating rod; a hammer body is installed inside the threaded barrel; a threaded ring is provided at the end of the hammer body; the hammer body is threadedly connected to the threaded barrel through the threaded ring; a fixing plate is fixedly connected to the bottom of the support plate; The fixing plate is located on the side of the threaded cylinder; the side wall of the fixing plate is fixedly connected to the first electric telescopic rod; the output end of the first electric telescopic rod is fixedly connected to the middle part of the hammer body; the middle part of the hammer body is connected to a connecting line; the end of the connecting line is connected to the display body. Through the above structure, the first electric telescopic rod can be operated to drive the hammer body to swing regularly, which reduces the need for workers to hold the hammer for hammering when using the hammer, thereby reducing the situation where the force of each hammering is different, resulting in deviations in the data. Regular hammering using the first electric telescopic rod can make the force and frequency of each hammering the same, so that the obtained data is more comparable.
[0008] Preferably, a flat plate is arranged above the support plate; a placement groove is opened on the top of the flat plate; multiple groups of second electric telescopic rods are fixedly connected to the two side walls of the placement groove; extrusion plates are fixedly connected to the ends of the multiple groups of second electric telescopic rods; the extrusion plates slide inside the placement groove and are symmetrically arranged. Through the above structure, the display body can be placed, clamped and fixed, thereby reducing the cumbersome steps of holding the display body when observing the display body. At the same time, the display body is fixed in the middle by two extrusion plates, which reduces the shaking caused by the swing of the hammer body, resulting in the display body falling from the inside of the placement groove, thereby causing damage.
[0009] Preferably, two groups of third electric telescopic rods are fixedly connected to the bottom of the tablet; the two groups of the third electric telescopic rods are located at the four corners of the bottom of the tablet, and are arranged opposite to each other in pairs; four bottom tubes are opened on the top of the support plate; the output end of the third electric telescopic rod extends to the inside of the bottom tube and is fixedly connected to the top of the support plate. Through the above structure, the device can be suitable for users of different heights. When the user is too high or too low, the height of the display body can be adjusted by starting the third electric telescopic rod, so that users of different heights can clearly and accurately see the screen of the display body to achieve data observation and comparison.
[0010] Preferably, a protective cover is fixedly connected to the top of the flat plate; the end of the protective cover is fixedly connected to the top of the extrusion plate; the protective cover is made of a flexible and deformable material; and multiple groups of the second electric telescopic rods are inside the protective cover. Through the above structure, the protective cover can protect the multiple groups of second electric telescopic rods, thereby reducing the amount of dust and impurities adsorbed on the surface of the second electric telescopic rods during operation, thereby causing blockage and making it difficult for the extrusion plate to slide.
[0011] Preferably, a connecting rod is connected in the middle of the multiple groups of the second electric telescopic rods; the connecting rod is located at the output end of the second electric telescopic rod. Through the above structure, the different movement trajectories of the multiple groups of second electric telescopic rods are reduced, resulting in different movement trajectories of the extrusion plates, and the loose fit between the extrusion plates and the side walls of the display body is reduced, resulting in the display body falling off from the middle of the two extrusion plates.
[0012] Preferably, sponge pads are directly fixed to the opposite surfaces of the two extrusion plates; the sponge pads are located near the bottom of the extrusion plates and are in contact with the bottom of the placement grooves. Through the above structure, direct contact between the extrusion plates with harder materials and the side walls of the display body is reduced, which causes the side walls of the display body to be pressurized and scratched.
[0013] The beneficial effects of the utility model are as follows:
[0014] 1. The low-strain controllable weight hammer described in the utility model drives the hammer body to swing regularly through the first electric telescopic rod, which reduces the need for workers to hold the hammer body for hammering when using the hammer body, thereby reducing the situation where the force of each hammering is different and the resulting data deviation occurs. The regular hammering using the first electric telescopic rod can make the force and frequency of each hammering the same, thereby making the obtained data more comparable.
[0015] 2. The low-strain controllable weight hammer described in the utility model places, clamps and fixes the display body, thereby reducing the cumbersome steps required to hold the display body when observing the display body. At the same time, the display body is fixed in the middle by two extrusion plates, which reduces the shaking caused by the swing of the hammer body, resulting in the display body falling from the inside of the placement slot and causing damage.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0023] like Figures 1 to 4As shown, a low-strain controllable weight hammer according to an embodiment of the utility model comprises a support plate 1; two groups of support rods 12 are fixedly connected to the bottom of the support plate 1; the two groups of support rods 12 are located at the four corners of the bottom of the support plate 1, and are arranged opposite to each other in pairs; a through hole 13 is opened at the bottom of the support plate 1, and the through hole 13 is located in the middle of the bottom of the support plate 1; a rotating rod 14 is fixedly connected to the inside of the through hole 13; a threaded barrel 15 is rotatably connected to the middle of the rotating rod 14; a hammer body 16 is installed inside the threaded barrel 15; the hammer body 16 The end of the support plate 1 is provided with a threaded ring 17; the hammer body 16 is threadedly connected to the threaded barrel 15 through the threaded ring 17; a fixing plate 18 is fixedly connected to the bottom of the support plate 1; the fixing plate 18 is located on the side of the threaded barrel 15; a first electric telescopic rod 19 is fixedly connected to the side wall of the fixing plate 18; the output end of the first electric telescopic rod 19 is fixedly connected to the middle of the hammer body 16; the middle of the hammer body 16 is connected to a connecting line 110; the end of the connecting line 110 is connected to a display body 111, and when working, the hammer body 16 is threadedly installed to the threaded barrel 15, at this time, by starting the first electric telescopic rod 19, as the first electric telescopic rod 19 is started, the output end of the first electric telescopic rod 19 will shrink back and forth, and the hammer 16 fixedly connected to the output end of the first electric telescopic rod 19 will also swing as the first electric telescopic rod 19 is started. At this time, the swing of the hammer 16 will drive the threaded tube 15 to swing back and forth in the middle of the rotating rod 14, and the swinging hammer 16 will hammer to the specified position. At the same time, the hammer 16 is used to hammer to the specified position, and the data of the hammer 16 hammering will be transmitted to the inside of the display body 111 through the connecting line 110, so as to facilitate the user to watch and compare and analyze the data. Through the above structure, the first electric telescopic rod 19 can work to drive the hammer 16 to swing regularly, which reduces the need for workers to hold the hammer 16 for hammering when using the hammer 16, thereby reducing the situation that the data deviation is caused by the different strength of each hammering. The regular hammering of the first electric telescopic rod 19 can make the strength and frequency of each hammering the same, so that the obtained data is more comparable.
[0024] like Figure 1 and Figure 3As shown, a flat plate 23 is arranged above the support plate 1; a placement slot 2 is opened on the top of the flat plate 23; multiple groups of second electric telescopic rods 22 are fixedly connected to both side walls of the placement slot 2; the ends of multiple groups of second electric telescopic rods 22 are fixedly connected to extrusion plates 21; the extrusion plates 21 slide inside the placement slot 2 and are symmetrically arranged. When working, the data of the hammer 16 knocking will be transmitted to the inside of the display body 111 through the connecting line 110. At this time, the knocking data can be obtained by observing the display body 111. At this time, by placing the display body 111 inside the placement slot 2, by starting multiple groups of second electric telescopic rods 22, as the multiple groups of second electric telescopic rods 22 are started, the output ends of the second electric telescopic rods 22 will be received as they are started. The display body 111 is retracted and extended. At this time, the output end of the second electric telescopic rod 22 will drive the two extrusion plates 21 to gradually approach each other. At this time, the extrusion plates 21 that are gradually approaching will move closer to the side walls of the display body 111 until they contact the side walls of the display body 111. At this time, the extrusion plates 21 that are in contact with the side walls of the display body 111 will fix the display body 111 in the middle. Through the above structure, the display body 111 can be placed, clamped and fixed, thereby reducing the cumbersome steps of holding the display body 111 when observing the display body 111. At the same time, the display body 111 is fixed in the middle by the two extrusion plates 21, which reduces the possibility of the display body 111 falling from the inside of the placement slot 2 due to shaking when the hammer body 16 swings, thereby reducing the possibility of damage.
[0025] like Figure 1 As shown, two groups of third electric telescopic rods 3 are fixedly connected to the bottom of the flat plate 23; the two groups of third electric telescopic rods 3 are located at the four corners of the bottom of the flat plate 23, and are arranged opposite to each other in pairs; four bottom tubes 31 are opened on the top of the support plate 1; the output end of the third electric telescopic rod 3 extends to the inside of the bottom tube 31, and is fixedly connected to the top of the support plate 1. When working, placing the display body 111 inside the placement slot 2 can facilitate the user to observe and compare data. At this time, by starting multiple third electric telescopic rods 3, as the multiple third electric telescopic rods 3 are started, the flat plate 23 can be driven to move up and down, and as the flat plate 23 moves, the display body 111 can be synchronously driven to move up and down. Through the above structure, the device can be suitable for users of different heights. When the user is too high or too low, the height of the display body 111 can be adjusted by starting the third electric telescopic rod 3, so that users of different heights can clearly and accurately see the screen of the display body 111 to achieve data observation and comparison.
[0026] like Figure 3As shown, a protective cover 4 is fixedly connected to the top of the flat plate 23; the end of the protective cover 4 is fixedly connected to the top of the extrusion plate 21; the protective cover 4 is made of a flexible deformable material; multiple groups of the second electric telescopic rods 22 are inside the protective cover 4. When working, by installing the protective cover 4 on the top of the flat plate 23, the multiple groups of second electric telescopic rods 22 can be surrounded by the inside of the protective cover 4, thereby protecting the multiple groups of second electric telescopic rods 22. At the same time, the material of the protective cover 4 is a deformable material. At this time, as the second electric telescopic rod 22 is started to drive the extrusion plate 21 to move, the moving extrusion plate 21 will drive the protective cover 4 to stretch and retract. Through the above structure, the protective cover 4 can protect the multiple groups of second electric telescopic rods 22, thereby reducing the excessive dust and impurities adsorbed on the surface of the second electric telescopic rod 22 during work, thereby causing blockage and making it difficult for the extrusion plate 21 to slide.
[0027] like Figure 3 As shown, a connecting rod 5 is connected in the middle of multiple groups of the second electric telescopic rods 22; the connecting rod 5 is located at the output end of the second electric telescopic rod 22. When working, by connecting the connecting rod 5 in the middle of multiple groups of the second electric telescopic rods 22, the connecting rod 5 can drive the multiple groups of the second electric telescopic rods 22 to move synchronously, so that the movement trajectories of the multiple groups of the second electric telescopic rods 22 can be the same. Through the above structure, the different movement trajectories of the multiple groups of the second electric telescopic rods 22, resulting in different movement trajectories of the extrusion plate 21, can be reduced, and the extrusion plate 21 and the side wall of the display body 111 are not tightly fitted, which causes the display body 111 to fall off from the middle of the two extrusion plates 21.
[0028] like Figure 4 As shown, the opposite surfaces of the two extrusion plates 21 are directly fixed with sponge pads 6; the sponge pads 6 are located near the bottom of the extrusion plates 21 and are in contact with the bottom of the placement slot 2. When working, the side walls of the display body 111 are squeezed by the two extrusion plates 21, and the display body 111 can be fixed in the middle of the two extrusion plates 21. At this time, a sponge pad 6 with a softer material is installed at the bottom of the extrusion plates 21, so that the sponge pad 6 can be first in contact with the side walls of the display body 111. Through the above structure, the direct contact between the extrusion plates 21 with a harder material and the side walls of the display body 111 is reduced, which causes the side walls of the display body 111 to be pressurized and scratched.
[0029] like Figure 1 and Figure 3As shown, the display body 111 is placed inside the placement groove 2, and the width of the placement groove 2 is slightly larger than the width of the display body 111. Through the above arrangement, the size of the placement groove 2 can be more adapted to the display body 111, so that the display body 111 can be more stably fixed inside the placement groove 2, thereby reducing the possibility of the display body 111 falling off from the inside of the placement groove 2 and causing damage.
[0030] During operation, the hammer 16 is threadedly installed inside the threaded barrel 15. At this time, the first electric telescopic rod 19 is started. As the first electric telescopic rod 19 is started, the output end of the first electric telescopic rod 19 will retract back and forth. At this time, the hammer 16 fixedly connected to the output end of the first electric telescopic rod 19 will also swing as the first electric telescopic rod 19 is started. At this time, the swing of the hammer 16 will drive the threaded barrel 15 to swing back and forth in the middle of the rotating rod 14. At this time, the swinging hammer 16 will hammer to the specified position. At the same time, the hammer 16 is used to hammer to the specified position, and the data of the hammer 16 hammering will be transmitted to the inside of the display body 111 through the connecting line 110, so that the user can watch it conveniently. According to the comparative analysis of the data, the data of the hammer 16 knocking will be transmitted to the inside of the display body 111 through the connecting line 110. At this time, the knocking data can be obtained by observing the display body 111. At this time, by placing the display body 111 in the placement slot 2, by starting multiple sets of second electric telescopic rods 22, as the multiple sets of second electric telescopic rods 22 are started, the output ends of the second electric telescopic rods 22 will shrink and extend as they are started. At this time, the output ends of the second electric telescopic rods 22 will drive the two extrusion plates 21 to gradually approach each other. At this time, the gradually approaching extrusion plates 21 will move closer to the side walls of the display body 111 until they contact the side walls of the display body 111. At this time, The extrusion plate 21 in contact with the side wall of the display body 111 will fix the display body 111 in the middle. Placing the display body 111 inside the placement slot 2 can facilitate the user to observe and compare data. At this time, by starting multiple third electric telescopic rods 3, as the multiple third electric telescopic rods 3 are started, the tablet 23 can be driven to move up and down. As the tablet 23 moves, the display body 111 can be synchronously driven to move up and down. By installing a protective cover 4 on the top of the tablet 23, multiple groups of second electric telescopic rods 22 can be surrounded by the protective cover 4, thereby protecting the multiple groups of second electric telescopic rods 22. At the same time, the material of the protective cover 4 is a deformable material. At this time, as the second electric telescopic rod 22 is started to drive the squeezing plate 21 to move, the moving squeezing plate 21 will drive the protective cover 4 to stretch and retract. By connecting the connecting rod 5 in the middle of the multiple groups of second electric telescopic rods 22, the connecting rod 5 can drive the multiple groups of second electric telescopic rods 22 to move synchronously, so that the movement trajectories of the multiple groups of second electric telescopic rods 22 can be the same. The side wall of the display body 111 is squeezed by the two squeezing plates 21, and the display body 111 can be fixed in the middle of the two squeezing plates 21. At this time, a sponge pad 6 with a softer material is installed at the bottom of the squeezing plate 21, so that the sponge pad 6 can be first in contact with the side wall of the display body 111.
