Description

Technical Field

[0001] The invention belongs to the technical field of testing devices, and in particular relates to an impact rammer testing device. Background Art

[0002] The rammer test device is generally composed of: a base plate, a test trough, an exciting force sensor, a shock absorbing assembly, a seat plate, a middle partition and other components. The exciting force sensor is attached to the base plate and there are multiple of them. The base plate, the exciting force sensor and the middle partition are installed by bolts for axial positioning. The seat plate and the middle partition are attached and fixed with bolts. The test trough is installed on the base plate by bolts. The bottom of the shock absorbing assembly is installed in the test trough by bolts. The rammer to be tested is fixed in the middle position of the shock absorbing assembly by bolts. The shock absorbing assembly includes shock absorbing springs, shock absorbing rubbers, shock absorbing plates and shock absorbing leather pads. There are four shock absorbing springs and they are connected with four shock absorbing rubber bolts. The shock absorbing plate is on the plane formed by the shock absorbing rubber and the shock absorbing spring. There is also a shock absorbing leather pad on the shock absorbing plate.

[0003] The function of the rammer test device is to place the rammer in the test trough. The exciting force generated after starting is transmitted to the exciting force sensor on the bottom plate through the test trough, and then the exciting force signal is transmitted to the signal processing unit through the pressure sensor. It can accurately measure whether the maximum exciting force of the rammer meets the requirements, and then predict and analyze the durability of the rammer, the working reliability of parts, and the possibility of quality problems.

[0004] At present, the rammer test device contains a variety of sensors. During normal use, they are easily affected by changes in external humidity. When the humidity in the test environment is high, moisture may invade the sensor, causing the insulation performance of the electronic components to deteriorate, causing signal interference or offset, and causing errors in the electrical signals output by the sensor. For force sensors based on the strain gauge principle, humidity may change the resistance value of the strain gauge, thereby affecting its accurate measurement of stress.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] like Figures 1 to 8 As shown, an impact rammer testing device in an embodiment of the present invention includes: a workbench 1, an airflow isolation mechanism 2, a guided moisture absorption mechanism 3 and a dust blocking mechanism 4.

[0023] like Figures 1 to 8 As shown, a test assembly 101 is provided on the upper side of the workbench 1 , and an airflow isolation mechanism 2 is fixedly installed on the lower side of the workbench 1 to isolate the test assembly 101 from contact with external moisture.

[0024] Among them, the airflow isolation mechanism 2 includes an airflow isolation positioning chamber 201, which provides corresponding space for the installation of an airflow isolation fan 202. The airflow isolation positioning chamber 201 is equipped with an airflow isolation fan 202, which can blow air so that the air is discharged from around the airflow isolation fixing block 203 to form an airflow wall, thereby isolating the air and moisture around the test component 101.

[0025] In addition, an airflow isolation fixing block 203 is provided on the upper side of the airflow isolation fan 202, which can not only fix the position of the test component 101, but also guide the air so that the air can be discharged better. A pair of isolation connecting pipes 204 are fixedly installed on the lower side of the airflow isolation positioning chamber 201, which connect the guide moisture absorption pipe 301 and the airflow isolation positioning chamber 201, so that the air in the airflow isolation positioning chamber 201 can be replenished from the guide moisture absorption pipe 301 at any time.

[0026] like Figures 1 to 7 As shown, the airflow isolation positioning bin 201 is arranged throughout the workbench 1, which is convenient for the installation of the airflow isolation positioning bin 201, improves the stability of the airflow isolation positioning bin 201, and makes the air in the airflow isolation positioning bin 201 better isolated from external moisture.

[0027] Among them, an airflow isolation fixing frame 205 is installed between the airflow isolation fixing block 203 and the airflow isolation positioning chamber 201, which improves the stability of the airflow isolation fixing block 203, locates the position of the airflow isolation fixing block 203, ensures the balance of the airflow isolation fixing block 203, reduces the possibility of the airflow isolation fixing block 203 tilting, and makes the air guiding effect of the airflow isolation fixing block 203 more ideal.

[0028] From the outside, the isolation connecting pipe 204 passes through the airflow isolation positioning chamber 201 and the guide moisture absorption pipe 301, connecting the airflow isolation positioning chamber 201 and the guide moisture absorption pipe 301, so that the air in the guide moisture absorption pipe 301 can better enter the airflow isolation positioning chamber 201, and the air in the airflow isolation positioning chamber 201 can be replenished at any time.

[0029] like Figures 1 to 6 As shown, an airflow isolation motor 206 is fixedly installed on the lower side of the airflow isolation positioning bin 201 , which can drive the rotation of the airflow isolation fan 202 and provide corresponding power for the rotation of the airflow isolation fan 202 .

[0030] In addition, the airflow isolation motor 206 is set through the airflow isolation positioning chamber 201, which is convenient for the connection between the airflow isolation motor 206 and the airflow isolation fan 202, so that the airflow isolation motor 206 can drive the rotation of the airflow isolation fan 202, and the airflow isolation motor 206 is connected to the airflow isolation fan 202.

[0031] like Figures 1 to 5 As shown, a guide desiccant mechanism 3 is fixedly installed on the isolation connecting pipe 204, which is used to reduce the moisture absorbed by the airflow isolation fan 202. The guide desiccant mechanism 3 includes a guide desiccant pipe 301, which facilitates the circulation of air and allows external air to enter the isolation connecting pipe 204 through the guide desiccant pipe 301.

[0032] Among them, a guide moisture-absorbing cotton 302 is fixedly installed in the guide moisture-absorbing pipe 301. After contacting with the outside air, it can absorb the moisture in the outside air, greatly reducing the possibility of moisture entering the airflow isolation positioning chamber 201.

[0033] In addition, a guide moisture absorption cone 303 is provided on the side of the guide moisture absorption pipe 301 away from the isolation connecting pipe 204, which can guide the air so that the air can better contact the guide moisture absorption leaf 304.

[0034] Among them, a plurality of evenly distributed guide moisture absorption pages 304 are installed between the guide moisture absorption cone 303 and the guide moisture absorption pipe 301, which can guide the air so that the air can contact the guide moisture absorption cotton 302 after entering the guide moisture absorption pipe 301, and the moisture is absorbed by the guided moisture absorption cotton 302.

[0035] like Figures 1 to 4 As shown, a guide moisture absorption fixed bin 305 is fixedly installed on the lower side of the guide moisture absorption pipe 301, which facilitates the installation of the guide moisture absorption cleaning bin 307, facilitates the sliding of the guide moisture absorption cleaning bin 307, and provides corresponding space for the sliding of the guide moisture absorption cleaning bin 307.

[0036] Among them, a pair of guided moisture absorption gravity tubes 306 are installed between the guided moisture absorption fixed warehouse 305 and the guided moisture absorption pipe 301, which not only fixes the guided moisture absorption fixed warehouse 305, but also connects the guided moisture absorption pipe 301 and the guided moisture absorption fixed warehouse 305, so that the moisture in the guided moisture absorption pipe 301 can enter the guided moisture absorption fixed warehouse 305 and be collected by the guided moisture absorption cleaning warehouse 307.

[0037] like Figures 1 to 5 As shown, the guided moisture absorption gravity tube 306 is arranged through the guided moisture absorption pipeline 301 and the guided moisture absorption fixed bin 305, and a guided moisture absorption cleaning bin 307 is slidably installed in the guided moisture absorption fixed bin 305, which can collect moisture and facilitate cleaning by the user.

[0038] like Figures 1 to 5 As shown, a dust-blocking mechanism 4 is provided in the guide moisture-absorbing duct 301, which is used to reduce the influence of dust on the moisture-absorbing effect of the guide moisture-absorbing cotton 302. The dust-blocking mechanism 4 includes a dust-blocking installation net 401, which can isolate the contact between dust and the guide moisture-absorbing cotton 302, reduce the influence of dust on the water-absorbing effect of the guide moisture-absorbing cotton 302, and at the same time reduce the probability of dust being soaked, thereby reducing the difficulty of cleaning the dust.

[0039] In addition, a pair of dust-blocking mounting rings 402 are installed between the dust-blocking mounting net 401 and the guide moisture absorption duct 301 to facilitate the rotation of the dust-blocking mounting net 401, thereby improving the stability and balance of the dust-blocking mounting net 401 and enabling the dust-blocking mounting net 401 to drive the dust-blocking impact block 407 to collide with the dust-blocking rebound plate 405.

[0040] like Figures 1 to 6 As shown, a plurality of evenly distributed dust-blocking force-bearing pages 403 are fixedly installed in the dust-blocking installation net 401. After being guided by the guide moisture-absorbing pages 304, the air will not only contact the guide moisture-absorbing cotton 302, but also blow the dust-blocking force-bearing pages 403, thereby driving the dust-blocking installation net 401 to rotate.

[0041] In addition, a dust-blocking positioning shaft 404 is fixedly installed in the isolating connecting pipe 204 to facilitate the rotation of the dust-blocking rebound plate 405, provide corresponding support and balance for the rotation of the dust-blocking rebound plate 405, and facilitate the installation of the dust-blocking rotation spring 406.

[0042] like Figures 1 to 7 As shown, a dust-blocking rebound plate 405 is rotatably installed outside the dust-blocking positioning shaft 404, which can collide with the dust-blocking impact block 407. The dust-blocking mounting net 401 can be continuously vibrated through the collision, thereby reducing the probability of the dust-blocking mounting net 401 being blocked and causing dust on the dust-blocking mounting net 401 to fall off.

[0043] A dust-blocking rotation spring 406 is installed between the dust-blocking positioning shaft 404 and the dust-blocking rebound plate 405 , so that the dust-blocking rebound plate 405 can return to its original position after each collision.

[0044] like Figures 1 to 7 As shown, a plurality of evenly distributed dust-blocking impact blocks 407 are fixedly installed in the dust-blocking installation net 401 , which can impact the dust-blocking rebound plate 405 , driving the dust-blocking installation net 401 to vibrate, and the dust-blocking rebound plate 405 matches the dust-blocking impact blocks 407 .

[0045] In one or more embodiments of the present invention, a dust-blocking attraction magnet 408 is fixedly installed in the isolating communication duct 204 , which can attract the dust-blocking collection bin 409 to achieve the purpose of fixing the position of the dust-blocking collection bin 409 .

[0046] Among them, a dust collection bin 409 is provided on the lower side of the dust blocking attraction magnet 408 , which can collect dust and facilitate cleaning by users. The dust collection bin 409 passes through the isolation connecting pipe 204 .

[0047] In addition, a dust-blocking ventilation net 410 is fixedly installed on the upper side of the dust-blocking collection bin 409, which can block dust while not affecting the circulation of air.

[0048] During specific use, when the test component 101 needs to test the rammer, the airflow isolation motor 206 is turned on, so that the airflow isolation motor 206 drives the airflow isolation fan 202 to rotate. Through the rotation of the airflow isolation fan 202, the airflow isolation positioning chamber 201 continuously draws the air in the guide moisture absorption pipe 301, and discharges it through the position of the airflow isolation fixed frame 205, forming an air wall to isolate the air around the test component 101 and the moisture in the air.

[0049] Air continuously enters the guided moisture absorption duct 301, and is guided by the guided moisture absorption cone 303 and the guided moisture absorption page 304. The air entering the guided moisture absorption duct 301 continuously contacts the guided moisture absorption cotton 302. Through the contact with the guided moisture absorption cotton 302, the moisture in the air will be absorbed by the guided moisture absorption cotton 302. After the guided moisture absorption cotton 302 continuously absorbs moisture, the moisture will gather and flow to the bottom of the guided moisture absorption duct 301 under the influence of gravity, and finally flow into the guided moisture absorption cleaning bin 307 through the guided moisture absorption gravity tube 306.

[0050] In order to reduce the influence of dust on the guided moisture-absorbing cotton 302, the setting of the dust-blocking installation net 401 can block the contact between dust and the guided moisture-absorbing cotton 302, and block the dust-bearing page 403 from being blown by the airflow. The dust-blocking installation net 401 will rotate in the guided moisture-absorbing duct 301, and drive the dust-blocking impact block 407 to rotate synchronously. The dust-blocking impact block 407 collides with the dust-blocking rebound plate 405, which can make the dust-blocking installation net 401 vibrate, thereby reducing the probability of blockage of the dust-blocking installation net 401. The dust is finally collected by the dust-blocking collection bin 409.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
