Description

Technical Field

[0001] This utility model relates to the field of impact resistance testing technology, specifically an impact resistance testing device for high-speed railway embedded parts. Background Technology

[0002] With the development of the times, railway transportation has become a common means of transportation for people's daily travel. Correspondingly, the construction of railways is an indispensable project. After the railway is built, it is necessary to set up some auxiliary transportation tools such as poles, road signs and directional signs next to the railway. This involves embedding some pre-embedded parts for the use of poles, road signs and directional signs. Therefore, pre-embedded parts are widely used in the construction of railway bridges and other fields and have great application prospects, making them frequently needed in the railway construction process.

[0003] CN218203618U discloses a boltless embedded part for railways, including an embedded part, anchor bars, and an installation head. Anchor bars are fixed around the bottom of the embedded part, and a limit plate is fixed to the bottom end of the anchor bars. A ground-gripping component is provided on the top of the limit plate. Embedded parts are exposed to high environmental pressure during use, so they need to undergo impact tests before being put into use to determine their stability. Conventional testing usually requires personnel to pull up an impact device and allow it to fall freely to impact the embedded part. Because the impact device is relatively heavy, pulling it is labor-intensive and inconvenient. Therefore, we propose an impact testing device for high-speed railway embedded parts to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1 and Figure 2As shown in the figure, an impact testing device for high-speed railway embedded parts according to one embodiment of the present invention includes a base plate 1, two support plates 2 fixed to the top of the base plate 1, and movable plates 3 slidably connected to each support plate 2. A U-shaped seat 4 is fixed between the two movable plates 3, an impact block 5 is fixed to the bottom of the U-shaped seat 4, and a lead screw 6 is fixed to the top of the U-shaped seat 4. Counterweights 7 are equidistantly sleeved on the surface of the lead screw 6, and two curved plates 15 are fixed to the surface of each counterweight 7, which makes it easier to install or remove the counterweights 7. A handwheel 8 for limiting the counterweights 7 is threadedly connected to the surface of the lead screw 6. A scale 9 is fixed to one side wall of one of the support plates 2, and an indicator block 10 fixed to one of the movable plates 3 is provided on one side of the scale 9. A device for driving the two movable plates 3 is provided on the top of the base plate 1. The drive assembly 11 moves the plate 3 upward. The top of the base plate 1 is fixed with a placement seat 12. When using this testing device, the embedded part to be tested can be placed on the top of the placement seat 12. Because the top of the placement seat 12 is fixed with anti-slip rubber pads or anti-slip plates, the embedded part will not shift during the testing process. Then, the drive assembly 11 drives the two moving plates 3 upward. After the moving plates 3 move upward, they will drive the U-shaped seat 4 upward. At this time, the operator can automatically increase or decrease the number of counterweights 7 according to the testing needs. With the cooperation of the scale 9 and the indicator block 10, the impact block 5 can be moved to a certain height. After the drive assembly 11 is operated to release the restriction on the moving plates 3, the impact block 5 will fall quickly, thereby realizing the impact resistance test of the embedded part on the top of the placement seat 12.

[0024] like Figure 3 As shown, the driving component 11 used to drive the two moving plates 3 to move upward in this utility model also has another form, which mainly includes a horizontal plate 18 fixed to the top of the two support plates 2. A hydraulic cylinder 19 is fixed to the top of the horizontal plate 18. The top end of the hydraulic cylinder 19 slides through the horizontal plate 18 and extends to its lower part and is fixed to a lifting plate 20. Two electromagnet plates 21 are fixed to the bottom of the lifting plate 20. In use, the hydraulic cylinder 19 is activated to drive the lifting plate 20 to move downward. After the lifting plate 20 moves downward, the two electromagnet plates 21 will be in contact with the moving plate 3. Then the electromagnet plates 21 can be energized. At this time, the hydraulic cylinder 19 drives the lifting plate 20 to move upward, which can indirectly drive the impact block 5 to move upward through the moving plate 3. After it moves to a suitable height, the energized electromagnet plates 21 are de-energized to release the restriction on the moving plate 3. Under the gravity of the counterweight block 7 at the top of the U-shaped seat 4, the impact block 5 can then fall freely and quickly.

[0025] like Figure 1 and Figure 2As shown, in some embodiments, the drive assembly 11 includes two cylinders 1101 fixed to the top of the base plate 1. Two support blocks 13 are fixed to the surface of each cylinder 1101, and the support blocks 13 are respectively fixedly connected to corresponding support plates 2, providing auxiliary support for the cylinders 1101 and making them more stable after fixing. Each cylinder 1101 has an intake pipe 1102 and two exhaust pipes 1103 connected and fixed. An electric intake check valve 1104 is installed on the intake pipe 1102, and an electric exhaust check valve 1105 is installed on each of the exhaust pipes 1103. A piston 1106 is provided inside each cylinder 1101, and a vertical rod 1107 is fixed to the top of each piston 1106, with the top of the vertical rod 1107 sliding through. The cylinder 1101 is fixedly connected to the corresponding movable plate 3. In use, the air inlet pipes 1102 of the two cylinders 1101 can be connected and fixed to the pipes of the air pump. When the air pump is inflating the inside of the cylinder 1101, the electric exhaust check valve 1105 is closed. Then, when the gas is sent into the inside of the cylinder 1101, the piston 1106 can be pushed to move upward. After the piston 1106 moves upward, the movable plate 3 can be moved upward to a suitable height through the vertical rod 1107. During testing, the electric exhaust check valve 1105 on the exhaust pipe 1103 is opened, and the gas inside the cylinder 1101 will be quickly discharged. At this time, under the gravity of the counterweight 7 at the top of the U-shaped seat 4, when the piston 1106 moves downward quickly, the movable plate 3 can be moved downward through the vertical rod 1107.

[0026] like Figure 1 As shown, in some embodiments, the top of the U-shaped base 4 is fixed with four limiting rods 14 for auxiliary limiting of the counterweight 7, which can guide the counterweight 7 to facilitate its disassembly or installation.

[0027] like Figure 1 As shown, in some embodiments, the sidewalls of the support plate 2 are provided with clearance grooves 16 that are adapted to the moving plate 3. The inner walls of the clearance grooves 16 are fixed with rubber buffer blocks 17. The clearance grooves 16 can make way for the moving plate 3 so that it can move up and down. When the moving plate 3 moves down quickly, it can prevent it from colliding directly with the support plate 2.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
