Description

Technical Field

[0001] This utility model belongs to the technical field of building material strength testing, and specifically relates to a building material strength testing device. Background Technology

[0002] After processing, building materials need to be tested for strength. This invention relates to a building material strength testing device (authorized publication number CN220419013 U3), which includes a positioning component and an adjustment and testing component. The positioning component is symmetrically arranged and includes an adjusting rod, a placement plate, a limiting rod, a fixing plate, an electric push rod, and a clamping plate. The adjustment and testing component includes a cross slide, an adjusting block, a hydraulic rod, and a test pressure block. This invention belongs to the field of strength testing technology, specifically a building material strength testing device that can clamp and fix building materials of different sizes, improving the diversity of testing, reducing testing costs, providing auxiliary support for weaker or longer materials to reduce breakage, and improving the flexibility of use.

[0003] While the clamping and fixing mechanism in the aforementioned application can handle materials of different lengths and dimensions, and can be fixed and tested under the same testing device without the need to prepare testing devices of different specifications, thus reducing testing costs and complexity, and simultaneously reducing the bending amplitude of building materials during testing to prevent breakage, it requires manual clamping and fixing of the left and right sides of the building material first, and then using an electric push rod to drive a separately set clamping structure to clamp and fix the front and rear sides of the building material. This makes the clamping and fixing operation cumbersome, and it is impossible to simultaneously clamp the left and right sides of the building material after clamping the front and rear sides, greatly reducing the efficiency of clamping, fixing and testing. Therefore, a building material strength testing device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a building material strength testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A building material strength testing device includes a testing platform. Supporting poles are fixedly attached to all four sides of the top of the testing platform. A common top plate is fixedly attached to the top of each of the four supporting poles. A hydraulic rod is connected to the bottom of the top plate via an electric cross slide. A test block is fixedly attached to the telescopic end of the hydraulic rod. A T-shaped platform is fixedly attached to the top of the testing platform below the test block. L-shaped clamping plates are slidably connected to the top of the testing platform on both sides of the T-shaped platform. Two symmetrically arranged sliding sleeves are fixedly attached to the bottom of each L-shaped clamping plate. The sliding sleeves are slidably fitted onto the outside of a guide rail with a T-shaped vertical cross-section. A drive mechanism connects the middle of the bottom of the two L-shaped clamping plates to the top of the testing platform. The structure includes two symmetrically arranged clamping blocks slidably connected to the inner sides of the two L-shaped clamping plates. Each clamping block has a first slider with an isosceles trapezoidal vertical cross-section fixed to its bottom end. The first sliders are slidably connected to a first groove in the inner bottom wall of the L-shaped clamping plate. Each clamping block has a second slider with an isosceles trapezoidal vertical cross-section fixed to its side wall away from the T-shaped platform. The second sliders are slidably connected to a second groove in the inner side wall of the L-shaped clamping plate. An adjustable synchronous transmission assembly is installed at the top of the testing platform and connected to the back of the four clamping blocks.

[0007] Preferably, the drive structure includes a movable block fixedly connected to the middle of the bottom end of each of the two L-shaped clamping plates. The two movable blocks are threaded with the same bidirectional screw. One end of the bidirectional screw is rotatably connected to the top of the testing platform through a bearing seat, and the other end is fixedly connected to the output shaft of the motor. The motor is fixedly connected to the top of the testing platform.

[0008] Preferably, the adjustable synchronous transmission assembly includes a fixed outer rod fixedly connected to the back of each clamping block, and a movable inner rod is movably inserted into an adjustment channel opened on the inner side of the fixed outer rod.

[0009] Preferably, the length of the movable inner rod is equal to the length of the fixed outer rod, and a transmission column is fixedly connected to the end of the movable inner rod away from the clamping block.

[0010] Preferably, the bottom ends of the transmission columns are movably connected to the Z-shaped transmission grooves opened at the top of the testing platform, and the diameter of the transmission columns is equal to the inner width of the Z-shaped transmission grooves.

[0011] Preferably, the top of the fixed outer rod is threaded with a hand screw at a position away from the clamping block, and the bottom end of the hand screw after being tightened abuts against the top of the movable inner rod.

[0012] Compared with the prior art, the building material strength testing device provided by this utility model has at least the following beneficial effects:

[0013] In this invention, when using the building material strength testing device, firstly, the building material plate to be tested is placed on top of the T-shaped platform, and the motor is started to drive the bidirectional screw to rotate. This causes the two L-shaped clamping plates to move towards each other, and simultaneously drives the bottom end of the transmission column to move in the corresponding transmission groove. With the shape design of the transmission groove, each L-shaped clamping plate has two sliding clamping blocks that can move towards each other a fixed distance, clamping and limiting the front and rear sides of the building material plate to be tested. Then, the two L-shaped clamping plates continue to move, clamping and limiting the left and right sides of the building material plate to be tested. This eliminates the need to manually clamp and limit the left and right sides first, and then use an electric push rod to drive the clamping and limiting of the front and rear sides, greatly reducing the operational complexity of clamping and limiting, and greatly improving the efficiency of building material strength testing.

[0014] Secondly, when it is necessary to clamp the front and back sides of building material panels of different widths, the hand screw can be loosened. Since the movable inner rod can be extended or retracted within the fixed outer rod, the initial distance between the two clamping blocks can be adjusted. After adjustment, the hand screw can be tightened, so that building material panels of different lengths and widths can be clamped and limited. Attached Figure Description

[0020] The present invention will be further described below with reference to the embodiments.

[0021] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Example

[0024] Although the clamping and fixing mechanism in the above application can fix and test materials of different lengths and sizes under the same testing device without the need to prepare testing devices of different specifications, thus reducing the cost and complexity of testing, and the bending amplitude of building materials is reduced during testing, preventing breakage, it is necessary to first manually clamp and fix the left and right sides of the building material, and then use an electric push rod to drive the additional clamping structure to clamp and fix the front and rear sides of the building material. This makes the clamping and fixing operation cumbersome, and it is impossible to clamp the left and right sides of the building material simultaneously after clamping the front and rear sides, greatly reducing the efficiency of clamping, fixing and testing.

[0025] For this purpose, please refer to Figure 1-3This utility model provides a building material strength testing device, comprising: a testing platform 1, with supporting rods 2 fixedly connected to the top four sides of the testing platform 1, and a top plate 21 fixedly connected to the top of the four supporting rods 2. A hydraulic rod 23 is connected to the bottom of the top plate 21 via an electric cross slide 22. A test block 24 is fixedly connected to the telescopic end of the hydraulic rod 23. A T-shaped platform 11 is fixedly connected to the top of the testing platform 1 below the test block 24. L-shaped clamping plates 14 are slidably connected to the top of the testing platform 1 on both sides of the T-shaped platform 11. Two symmetrically arranged sliding sleeves 13 are fixedly connected to the bottom of each L-shaped clamping plate 14. The sliding sleeves 13 are slidably fitted onto the outside of a guide rail 12 with a T-shaped vertical cross section. The middle of the bottom of the two L-shaped clamping plates 14... A drive structure is connected to the top of the testing table 1. Two symmetrically arranged clamping blocks 141 are slidably connected to the inner sides of the two L-shaped clamping plates 14. The bottom end of each clamping block 141 is fixed with a first slider 142 with an isosceles trapezoidal vertical cross section. The first slider 142 is slidably connected to the first groove opened in the bottom wall of the inner side of the L-shaped clamping plate 14. The side wall of each clamping block 141 opposite to the T-shaped table 11 is fixed with a second slider 143 with an isosceles trapezoidal vertical cross section. The second slider 143 is slidably connected to the second groove opened in the inner side wall of the L-shaped clamping plate 14. An adjustable synchronous transmission assembly 3 is installed at the top of the testing table 1 and is connected to the back of the four clamping blocks 141.

[0026] Except for the adjustable synchronous transmission component 3, the working principles of all components on this device are roughly the same as those in the prior art applications.

[0027] Further as Figure 1-3 As shown, it is worth noting that in order to enable the two L-shaped clamping plates 14 to move automatically toward each other or away from each other without manual intervention, a drive structure is provided that includes a moving block 15 fixedly connected to the middle of the bottom end of each of the two L-shaped clamping plates 14. The same bidirectional screw 16 is threaded onto the two moving blocks 15. One end of the bidirectional screw 16 is rotatably connected to the top of the testing table 1 through a bearing seat, and the other end is fixedly connected to the output shaft of the motor 17, which is fixedly connected to the top of the testing table 1.

[0028] Further as Figure 1-3As shown, it is worth noting that in order to clamp and limit the front and rear sides of the building material panel, and then actively clamp and limit the left and right sides of the building material panel, an adjustable synchronous transmission assembly 3 is provided. This assembly includes a fixed outer rod 31 fixed to the back of each clamping block 141. An adjustable channel is opened on the inner side of the fixed outer rod 31, and a movable inner rod 32 is movably inserted therein. The length of the movable inner rod 32 is equal to the length of the fixed outer rod 31. A transmission column 33 is fixedly connected to the end of the movable inner rod 32 away from the clamping block 141. The bottom end of the transmission column 33 is movably connected to the Z-shaped transmission groove 35 opened at the top of the testing table 1. The diameter of the transmission column 33 is equal to the inner width of the Z-shaped transmission groove 35. A hand screw 34 is threadedly connected to the top of the fixed outer rod 31 at a position away from the clamping block 141. The bottom end of the hand screw 34 after being locked is pressed against the top of the movable inner rod 32.

[0029] The shape of the Z-shaped transmission groove 35 is shown in the attached figure. The middle part of the Z-shaped transmission groove 35 is provided with an inclined section. The inclined section is mainly to cooperate with the movement of the transmission column 33 to promote the movement of the clamping block 141.

[0030] In summary: When using this building material strength testing device, firstly, the building material slab to be tested is placed on top of the T-shaped platform 11, and the bidirectional screw 16 is driven to rotate by starting the motor 17. This causes the two L-shaped clamping plates 14 to move towards each other, and simultaneously drives the bottom end of the transmission column 33 to move in the corresponding transmission groove. The shape design of the transmission groove allows two sliding clamping blocks 141 on each L-shaped clamping plate 14 to move relative to each other a fixed distance, clamping and limiting the front and rear sides of the building material slab to be tested. Then, the two L-shaped clamping plates 14 continue to move, clamping and limiting the left and right sides of the building material slab to be tested. The clamping and limiting mechanism is located on the right side, eliminating the need for manual clamping and limiting on the left and right sides first, and then using an electric push rod to drive the clamping and limiting mechanism on the front and rear sides. This greatly reduces the operational complexity of clamping and limiting and significantly improves the efficiency of building material strength testing. Furthermore, when it is necessary to clamp the front and rear sides of building material panels of different widths, the hand screw 34 can be loosened. Since the movable inner rod 32 can be extended or retracted within the fixed outer rod 31, the initial distance between the two clamping blocks 141 can be adjusted. After adjustment, the hand screw 34 can be tightened, thus enabling clamping and limiting of building material panels of different lengths and widths.
