Description

Technical Field

[0001] This utility model belongs to the technical field of impact resistance testing device for building materials, and more specifically, it relates to an impact resistance testing device for building materials. Background Technology

[0002] Building materials such as flooring and glass need to undergo impact resistance testing before leaving the factory to verify whether their strength is up to standard. The falling ball impact test is the most common testing method, and the falling ball impact testing machine is the most common testing equipment.

[0003] Based on the above, the inventors have discovered the following problems:

[0004] Existing impact testing devices for building materials require operators to retrieve the steel balls from the material fragments after they fall, which is very inconvenient. Furthermore, because the materials include glass and other materials, this can easily cause injury to the operators. In addition, the devices cannot recycle the small waste generated when substandard building materials are tested.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a building material impact resistance testing device in order to achieve a more practical purpose. Utility Model Content

[0006] The purpose and effectiveness of this utility model's impact resistance testing device for building materials are achieved through the following specific technical means:

[0007] An impact resistance testing device for building materials includes a base, an electric telescopic rod, a cross arm, a connecting shaft, and a motor. The base has an electric telescopic rod and a collecting assembly on its upper end. A sliding seat is fitted onto the electric telescopic rod and connected to it by bolts. A cross arm is connected to the other end of the sliding seat, and a three-jaw chuck is connected to the other end of the cross arm. A ball-gripping plate is mounted on the jaws of the three-jaw chuck. A roller is positioned above the three-jaw chuck, and a steel wire tube is mounted on the roller. The steel wire tube passes through the center of the three-jaw chuck and is connected to an electromagnetic chuck. A steel ball is attracted to the other end of the electromagnetic chuck, and the other end of the steel wire tube is wound around the connecting shaft. One end of the connecting shaft is connected to the output end of the motor.

[0008] Furthermore, the cross arm is an electrically telescopic plate, the roller is movably connected to the cross arm, and the roller is located directly above the three-jaw chuck, and the steel ball is connected to the three-jaw chuck through a ball clamping plate.

[0009] Furthermore, the steel ball is made of ordinary steel with high iron content, and the electromagnetic chuck controls the adsorption force and demagnetization process of the electromagnetic chuck through current control.

[0010] Furthermore, the collection assembly includes a guide groove, a support column, a connecting frame, a collection box, and a pull-out plate. The collection box has support columns at its four corners, and a guide groove is fixedly provided on the support column. The lower end of the guide groove is fixedly connected to the connecting frame, and a pull-out plate is provided between the connecting frame and the guide groove. The lower end of the connecting frame is provided with a drawer.

[0011] Furthermore, the bottom end of the guide groove is provided with a slot, the middle of the connecting frame is provided with a sliding groove, the pull-out plate is connected to the connecting frame through the sliding groove, the middle of the connecting frame is provided with a through hole, and the slot, the through hole and the center of the drawer are aligned.

[0012] Furthermore, a power supply device is provided inside the connecting shaft, and the steel wire tube passes through the connecting shaft and is connected to the power supply device. A power cord is provided inside the steel wire tube, and the power cord is connected to the electromagnetic chuck. The other end of the power cord is connected to the power supply device.

[0013] Furthermore, the entire collection component is made of iron-free material, and the sidewall of the guide groove is designed with an inclined surface. The center position of the three-jaw chuck is vertically aligned with the center position of the collection component in the initial state of the device.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention utilizes the combination of an electromagnetic chuck, a steel wire tube, a connecting shaft, a motor, and a guide groove to allow a steel ball to automatically return to the three-jaw chuck after falling into the guide groove, preparing for the next step of testing. When the steel ball falls freely to impact the building materials on the support column, the guide groove has a sloping sidewall design. After falling, the steel ball slides along the guide groove to the groove opening, where it is attracted by the cross arm, motor, steel wire tube, and electromagnetic chuck. The motor then drives the steel wire tube to wind around the connecting shaft, moving the steel ball up to the three-jaw chuck for clamping. At the same time, the attraction force of the electromagnetic chuck is released, allowing the device to return to its initial state and prepare for the next testing process.

[0016] By designing the collection components, when construction material waste slides along the guide groove to the groove opening, pulling the pull plate allows the waste to enter the drawer through the groove opening and through holes, thereby achieving the recycling and cleaning of the waste.

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 4 As shown:

[0028] This utility model provides a building material impact resistance testing device, including a base 1, an electric telescopic rod 2, a cross arm 4, a connecting shaft 14, and a motor 5. The upper end of the base 1 is provided with the electric telescopic rod 2 and a collecting assembly 6. A sliding seat 3 is sleeved on the electric telescopic rod 2. The sliding seat 3 is connected to the electric telescopic rod 2 by bolts 7. The other end of the sliding seat 3 is connected to the cross arm 4. The other end of the cross arm 4 is connected to a three-jaw chuck 9. The jaws of the three-jaw chuck 9 are equipped with ball clamping plates 8. A roller 10 is provided above the three-jaw chuck 9. A steel wire tube 11 is provided on the roller 10. The steel wire tube 11 passes through the center of the three-jaw chuck 9 and is connected to an electromagnetic chuck 12. The other end of the electromagnetic chuck 12 is attracted to a steel ball 13. The other end of the steel wire tube 11 is wound around the connecting shaft 14. One end of the connecting shaft 14 is connected to the output end of the motor 5.

[0029] The horizontal arm 4 is an electrically telescopic plate, the roller 10 is movably connected to the horizontal arm 4 and the roller 10 is located directly above the three-jaw chuck 9, and the steel ball 13 is connected to the three-jaw chuck 9 through the ball clamping plate 8. The design of the horizontal arm 4 as an electrically telescopic plate can detect different positions of the building material being tested.

[0030] The steel ball 13 is made of ordinary steel with high iron content. The electromagnetic chuck 12 controls the adsorption force and demagnetization process of the electromagnetic chuck 12 through current control. With the design of the steel ball 13 being made of ordinary steel with high iron content, the connection between the steel ball 13 and the electromagnetic chuck 12 is more secure in cooperation with the electromagnetic chuck 12.

[0031] The collection component 6 includes a guide groove 601, a support column 602, a connecting frame 603, a collection box 604, and a pull-out plate 605. The collection box 604 has support columns 602 at its four corners, which are used to support the building materials to be tested. The guide groove 601 is fixedly provided on the support column 602. The lower end of the guide groove 601 is fixedly connected to the connecting frame 603. The pull-out plate 605 is provided between the connecting frame 603 and the guide groove 601. The lower end of the connecting frame 603 is provided with a drawer 606.

[0032] The guide groove 601 has a slot 607 at its bottom end, the connecting frame 603 has a sliding groove 608 in the middle, the pull-out plate 605 is connected to the connecting frame 603 through the sliding groove 608, and the connecting frame 603 has a through hole 609 in the middle. The slot 607, the through hole 609 and the drawer 606 are all centered. This design allows construction waste to easily enter the drawer 606 through the slot 607 and the through hole 609.

[0033] The connecting shaft 14 is equipped with a power supply device, and the steel wire tube 11 passes through the connecting shaft 14 and is connected to the power supply device. The steel wire tube 11 is equipped with a power line, which is connected to the electromagnetic chuck 12. The other end of the power line is connected to the power supply device. The power line can provide positive or reverse voltage to the electromagnetic chuck 12, thereby controlling the adsorption force and demagnetization of the electromagnetic chuck 12.

[0034] The collection component 6 is made of iron-free material, and the side wall of the guide groove 601 is designed with a slope. The slope design of the guide groove 601 can move the steel ball 13 and the waste building materials to the groove opening 607 for convenient subsequent processing. The center position of the three-jaw chuck 9 is vertically aligned with the center position of the collection component 6 in the initial state of the device.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When using this device, first check its integrity. When impact testing of building materials is required, place the building materials to be tested on the support column 602 inside the collection component 6. At this time, the electromagnetic chuck 12 is under reverse voltage and has no adsorption force. The three-jaw chuck 9 fixes the steel ball 13 through the control device. Through the cooperation of the horizontal arm 4 and the sliding seat 3, the steel ball 13 is moved above the position of the building material that needs to be tested for pressure resistance. Then, by releasing the fixation of the steel ball 13 by the three-jaw chuck 9, the steel ball 13 falls freely under gravity, impacting the building material. After the steel ball 13 falls, because the guide groove 601 is designed with an incline, the steel ball 13 naturally slides to the groove opening 607. Then, the movement of the horizontal arm 4 drives the electromagnetic chuck 12 to move to the groove opening 607. When the device is above 07, start motor 5 rotates forward. Under the gravity of electromagnetic chuck 12, the steel wire tube 11 wound on the connecting shaft 14 moves from the connecting shaft 14 to the electromagnetic chuck 12. At this time, electromagnetic chuck 12 falls to the position of steel ball 13 due to gravity. Then, start motor 5 and introduce positive voltage into electromagnetic chuck 12 through the power line in steel wire tube 11, so that electromagnetic chuck 12 has an adsorption force. At this time, under the adsorption force of electromagnetic chuck 12, steel ball 13 is tightly connected to electromagnetic chuck 12. Then, start motor 5 rotates in reverse, driving steel wire tube 11 to wind around the connecting shaft 14, so that steel ball 13 rises to the center of three-jaw chuck 9. Then, start motor 5 and control three-jaw chuck 9 to clamp steel ball 13. At the same time, introduce reverse voltage to make electromagnetic chuck 12 lose its adsorption force, and the device returns to the initial state. When the building material being tested is substandard and residue is generated due to the impact of the steel ball 13, the residue slides to the slot opening 607 through the guide groove 601. Pulling the pull plate 605 allows the residue to pass through the slot opening 607 and the through hole 609 to the drawer 606. Then, pulling the drawer 606 cleans and recycles the residue.
