[0002] In order to improve the wear resistance, corrosion resistance and overall deformation resistance of steel plates, a coating is usually applied to the surface of the steel plates to achieve the above effects. After coating, different batches of steel plates are usually randomly selected and subjected to impact tests by manual tapping. However, due to the limited strength of manual tapping and the inability to ensure that the tapping angle and tapping position meet the test requirements every time, it not only fails to reflect the true coating effect, but also wastes corresponding human resources.

[0044] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0045] The most critical concept of the utility model is that the impact head is lifted to a certain height, so as to provide sufficient potential energy for subsequent impact tests; when the impact head is released and under the guidance of the guide impact frame, the impact head can hit the designated position of the steel plate along a predetermined route every time, thereby avoiding the impact head from shaking and deviating during the falling process, which affects the landing point accuracy and further affects the authenticity of the impact test.

[0046] Please refer to Figures 1 to 3The plate impact testing device provided by the utility model comprises a workbench 1, and a lifting winch assembly 2, a guide impact frame 3, and an impact head 4 arranged on the workbench 1;

[0047] The impact head 4 is slidably connected to the guide impact frame 3;

[0048] The impact head 4 is connected to the lifting winch assembly 2 through a twisted rope, and the lifting winch assembly is used to lift the impact head 4 or drive the impact head 4 to fall freely toward the workbench 1.

[0049] Specifically, the guide impact frame 3 and the impact head 4 are both provided with corresponding pulley assemblies, so as to provide structural support for the winding work of the twisted rope and ensure that the lifting work of the impact head 4 can be carried out normally.

[0050] From the above description, it can be seen that the beneficial effects of the utility model are: providing a plate impact testing device, which drives the impact head 4 to be lifted to a certain height by lifting the winch assembly 2, thereby providing sufficient potential energy for subsequent impact tests; when the impact head 4 is released and under the guidance of the guide impact frame 3, the impact test of the steel plate can be completed; compared with the existing impact testing scheme, it can ensure that the impact head 4 can hit the designated position of the steel plate along a predetermined route every time, thereby avoiding the shaking and deviation of the impact head 4 during the falling process, thereby affecting the landing point accuracy of the impact head 4; at the same time, the plate impact testing device can replace manual impact testing of the coating, so it can better guarantee the reliability and authenticity of the test results.

[0051] Furthermore, a positioning groove 11 is provided on the workbench 1;

[0052] The opening of the positioning groove 11 is located on the moving path of the impact head 4 , and the impact end of the impact head 4 is arranged toward the groove bottom of the positioning groove 11 .

[0053] Furthermore, a positioning seat 111 is provided at the bottom of the positioning groove 11;

[0054] A stopper 112 is provided at one end of the positioning seat 111 away from the positioning groove 11;

[0055] The impact end of the impact head 4 and the limiting member 112 are arranged opposite to each other.

[0056] It can be seen from the above description that, under normal circumstances, placing the steel plate in the positioning groove 11 can limit the steel plate, thereby preventing the steel plate from affecting the landing point of the impact head 4 on the steel plate due to changes in position during the test, thereby affecting the final test data; and for some special surface shapes, such as steel plates with protrusions, the protrusions can be further matched with the limiting members 112 on the positioning seat 111, that is, the limiting members 112 are usually a retaining structure with a certain height, thereby forming a groove-shaped limiting structure on the positioning seat 111 that can match the protrusions on the steel plate, and then fixing the protrusions on the steel plate in the limiting structure through a sleeve or clamping fixing method, which can further achieve the effect of fixing the steel plate and preventing the steel plate from shaking.

[0057] Further, the guide impact frame 3 includes at least two guide rods 31;

[0058] The axis of the guide rod 31 is perpendicular to the plane where the workbench 1 is located;

[0059] The impact head 4 is slidably connected to the guide rod 31 .

[0060] As can be seen from the above description, the design makes specific improvements to the component structure of the guide impact frame 3, thereby providing structural support for the impact head 4 to maintain stability during the free fall process.

[0061] Furthermore, an elastic element 32 is sleeved on the outer side of one end of the guide rod 31 close to the workbench 1 .

[0062] Further, the impact head 4 includes a support plate 41 and an impact block 42 connected to each other;

[0063] The support plate 41 is slidably connected to the guide rod 31;

[0064] The impact block 42 is disposed toward the workbench 1 , and the length of the impact block 42 is smaller than the length of the elastic element 32 in the initial state.

[0065] From the above description, it can be seen that the elastic element 32 can effectively buffer the impact force caused by the falling of the impact head 4, and ensure that the length of the impact block 42 is less than the length of the elastic element 32 in the initial state, so that the impact head 4 can immediately contact the elastic element 32 to perform a force unloading action within a short time after colliding with the steel plate to be tested, thereby avoiding the impact block 42 from penetrating the steel plate due to excessive impact force, thereby affecting subsequent data analysis work.

[0066] Further, the lifting winch assembly 2 comprises a hand wheel 21, a main shaft 22 and a winch disc 23 which are sequentially connected in transmission;

[0067] The output end of the hand wheel 21 and the main shaft 22 form a worm gear structure.

[0068] From the above description, it can be seen that the design has made specific modifications to the component structure of the lifting winch assembly 2, so as to provide structural support for the staff to smoothly lift the impact head 4 to the specified height, thereby ensuring that the output end of the handwheel 21 and the main shaft 22 form a worm gear structure, which can effectively compress the space occupancy rate of the lifting winch assembly 2, thereby making the equipment more sophisticated.

[0069] Furthermore, the lifting winch assembly 2 also includes a clutch assembly 24;

[0070] The main shaft 22 is sleeved with a first gear 25;

[0071] The input end of the capstan 23 is provided with a second gear 26;

[0072] The clutch assembly 24 can drive the first gear 25 to reciprocate along the axis of the main shaft 22 to control the first gear 25 to approach or move away from the second gear 26;

[0073] When the first gear 25 and the second gear 26 are meshed, the main shaft 22 and the capstan 23 are connected in transmission;

[0074] When the first gear 25 and the second gear 26 are meshed, the capstan disc 23 can rotate freely.

[0075] It can be seen from the above description that by controlling the clutch of the first gear 25 and the second gear 26, the lifting and free falling of the impact head 4 can be effectively controlled, that is, when the first gear 25 and the second gear 26 are meshed with each other, the staff can turn the hand wheel 21 to drive the main shaft 22 and the capstan 23 to rotate in turn, thereby realizing the lifting of the impact head 4; because the hand wheel 21 and the main shaft 22 constitute a worm gear structure, when they stop rotating, the impact head 4 can be suspended at a certain height when self-locking. When the impact head 4 needs to be released, it is only necessary to separate the first gear 25 from the second gear 26 through the clutch assembly 24, so as to release the restriction of the worm gear structure on the capstan 23, so that the capstan 23 can rotate freely, thereby completing the free fall of the impact head 4.

[0076] Further, the clutch assembly 24 includes a support frame 241, a pry bar 242, a reset assembly and an elastic torsion spring;

[0077] The pry bar 242 is hinged to the support frame 241;

[0078] The reset assembly is hinged to the support frame 241 through an elastic torsion spring;

[0079] A portion of the pry bar 242 and a portion of the reset assembly respectively abut against both end surfaces of the first gear 25 .

[0080] Further, the reset assembly includes a movable block 243 and a sleeve 244 that are hinged to each other;

[0081] One end of the movable block 243 away from the sleeve 244 is hinged to the support frame 241 through an elastic torsion spring;

[0082] The sleeve 244 is slidably connected to the main shaft 22 , and one end of the sleeve 244 away from the movable block 243 abuts against the end surface of the first gear 25 .

[0083] As can be seen from the above description, the design has made specific modifications to the composition structure of the clutch assembly 24, thereby providing structural support for the clutch assembly 24 to drive the first gear 25 to reciprocate on the main shaft 22 to achieve the clutching work of the first gear 25 and the second gear 26.
