Description

Technical Field

[0001] This invention relates to the field of performance testing technology for lead-zinc tailings sand concrete, specifically a testing device for the static and dynamic performance of lead-zinc tailings sand concrete. Background Technology

[0002] Lead-zinc tailings sand mixed concrete can be used as a building material. Before its reuse, lead-zinc tailings sand mixed concrete undergoes static and dynamic performance tests to ensure its safety. The concrete block splitting test is one method for testing its static and dynamic performance. The compression testing machine is the instrument used for this test. The tester places the specimen into a splitting fixture, places the fixture on the lower pressure plate of the compression testing machine, and after alignment, presses the upper pressure plate against the upper pad of the fixture. The machine is then started for the test. Lead-zinc tailings sand concrete specimens come in both cubic and cylindrical shapes. When testing the specimen, it is necessary to change to a suitable splitting fixture as needed to clamp and position the cylindrical specimen in both upright and horizontal positions. Before placing the splitting fixture on the lower pressure plate for testing, alignment is required to eliminate eccentric pressure. The testing personnel place the splitting fixture flat on the lower pressure plate and then complete the alignment by visual observation and manual forceful movement. This operation is not convenient enough, as the operator cannot flexibly and effectively adjust and position the cylindrical specimen in the splitting fixture for both horizontal and vertical positions. At the same time, it is also impossible to quickly complete the alignment and positioning of the splitting fixture after eccentricity adjustment, which reduces the flexibility and efficiency of the device. Summary of the Invention

[0003] The purpose of this invention is to provide a testing device for the static and dynamic properties of lead-zinc tailings sand concrete, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A testing device for the static and dynamic properties of lead-zinc tailings sand concrete includes a test operation control box. An equipment assembly frame is fixedly connected to the side of the control box. A lower pressure plate is fixedly connected inside the equipment assembly frame. A splitting clamp is detachably connected to the top of the lower pressure plate. Two symmetrically distributed test block positioning modules are rotatably connected to the inside of the left and right side walls of the splitting clamp. Two symmetrically distributed eccentricity elimination modules are fixedly connected to the bottom of the splitting clamp. Two linearly distributed arc-shaped side abutments are slidably connected to the inner side of the splitting clamp. The test block positioning module includes a combined vertical plate, two rotating rods, and two screw-in housings. The vertical plate is rotatably connected to the corresponding side wall of the splitting fixture via two rotating rods. The outer wall of the rotating rod is provided with a threaded connection part. The threaded housing is threaded to the outside of the threaded connection part to realize the positioning of the test block positioning module. The test block positioning module inserts a clamping bar to realize the positioning of the test block inside the splitting fixture. The eccentricity elimination module includes a connecting cylinder, an aligning connecting vertical rod, and a moving ball. The top of the lower bearing plate is fixedly connected with two aligning connecting rows corresponding to the eccentricity elimination module. The aligning connecting vertical rod and the moving ball are inserted into the aligning connecting rows to realize the positioning of the splitting fixture above the lower bearing plate.

[0006] Furthermore: the two rotating rods are symmetrically fixedly connected to the top and bottom of the combined vertical plate, one above the other. The other end of the rotating rod is rotatably connected to the splitting clamp. The threaded housing is fixedly connected to the side wall of the splitting clamp corresponding to the rotating rod. The threaded housing is sleeved on the outside of the rotating rod and is located above the threaded connection part. The threaded housing is threadedly connected to the threaded connection part.

[0007] Furthermore: the connecting cylinder is fixedly connected inside the bottom end of the splitting clamp, the aligning connecting rod is slidably connected inside the connecting cylinder, and the moving ball is rotatably connected inside the bottom end of the aligning connecting rod.

[0008] Furthermore: the alignment connecting row has four mating cavities with the same diameter as the alignment connecting vertical rod, and two symmetrically distributed pull plates are inserted into the lower bearing plate, with the two pull plates respectively inserted into the two alignment connecting rows.

[0009] Furthermore: two symmetrically distributed combined moving modules are fixedly connected to the outside of the splitting clamp. The combined moving module includes two fixed plates and a guide crossbar. The two fixed plates are symmetrically fixedly connected to the left and right walls of the splitting clamp, and the guide crossbar is fixedly connected between the two fixed plates.

[0010] Furthermore: the guide crossbar is located outside the splitting clamp, and two symmetrically distributed connecting seats are fixedly connected to the outer wall of the arc-shaped side abutment plate, and the two connecting seats are slidably connected to the outside of the two guide crossbars respectively.

[0011] Furthermore, the outer wall of the guide crossbar is provided with several spherical grooves that are equidistantly distributed in a straight line.

[0012] Furthermore: the top of the splitting clamp is detachably connected to an upper pad block, and the inner walls on both the left and right sides of the splitting clamp are provided with clearance receiving grooves. The width of the clearance receiving groove is greater than the width of the arc-shaped side abutment plate, and the clearance receiving groove realizes the reception of the arc-shaped side abutment plate and the connecting seat.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This invention uses four specimen positioning modules connected to the left and right side walls of a splitting fixture to clamp and position cylindrical specimens. A combined vertical plate is used to insert clamping rods. The combined vertical plate can rotate inward and outward on the corresponding side wall of the splitting fixture via two rotating rods, and is fixed after rotation by a screw-in housing. Two arc-shaped side abutments slidably connected to the inside of the splitting fixture can move horizontally along the long side of the splitting fixture, achieving flexible adjustment of the angle of the combined vertical plate and the position of the arc-shaped side abutments. This provides high operational convenience. By changing the angle of the combined vertical plate, the angle of the clamping rods can be changed, and angled clamping rods can also be inserted. Combined with the arc-shaped side abutments that can be adjusted to fit tightly against the outer wall of the cylindrical specimen, it can adapt to the clamping and positioning of the cylindrical specimen in both upright and horizontal positions. This allows testing personnel to flexibly and effectively adjust and position the cylindrical specimen in both horizontal and vertical positions within the splitting fixture.

[0015] 2. This invention connects the lower pressure plate by setting two symmetrically fixed eccentricity elimination modules at the bottom of the splitting fixture. The alignment connecting rod can move into the connecting cylinder fixed at the bottom of the splitting fixture, and can also move outward from the inside of the connecting cylinder. When the inspector places the splitting fixture on the lower pressure plate, the moving ball will first contact the lower pressure plate. The splitting fixture moves downward, causing the alignment connecting rod to move into the connecting cylinder. The movement of the moving ball at the top of the lower pressure plate improves the smoothness of the inspector's work when adjusting the position of the splitting fixture. After the moving ball moves to the corresponding alignment connecting row in the lower pressure plate, it pulls the two pull plates outward to expose the mating cavity in the alignment connecting row, so that the alignment... The vertical connecting rod and the moving ball automatically descend into the mating cavity within the alignment connecting row, completing the positioning of the splitting fixture on the lower pressure plate. This operation is highly convenient, eliminating the need for visual observation and forceful pushing by the inspector to align the splitting fixture. The alignment connecting row has four mating cavities distributed from front to back. Through the cooperation of these four cavities and the vertical connecting rod, the eccentricity of the splitting fixture can be adjusted and positioned. This allows inspectors to quickly complete the alignment, eccentricity adjustment, and post-adjustment positioning of the splitting fixture, improving the flexibility and efficiency of the device.

Specific mechanical structures of the present invention will be described in conjunction with the following references. Figures 1 to 5 The detailed description of the structure will be clearly presented. All structural contents mentioned in the following embodiments are based on the accompanying drawings.

[0024] Please see Figures 1-5 In this embodiment of the invention, a testing device for the static and dynamic properties of lead-zinc tailings sand concrete includes a test operation control box 1. An equipment assembly frame 11 is fixedly connected to the side of the test operation control box 1. A lower pressure plate 2 is fixedly connected inside the equipment assembly frame 11. A splitting clamp 3 is detachably connected to the top of the lower pressure plate 2. Two symmetrically distributed test block positioning modules 4 are rotatably connected inside the left and right side walls of the splitting clamp 3. Two symmetrically distributed eccentricity elimination modules 5 are fixedly connected to the bottom of the splitting clamp 3. Two linearly distributed arc-shaped side abutment plates 6 are slidably connected to the inner side of the splitting clamp 3. The test block positioning module 4 includes a combined vertical plate 41, two rotating rods 42, and two screw-in shells. 43. The combined vertical plate 41 is rotatably connected to the corresponding side wall of the splitting fixture 3 through two rotating rods 42. The outer wall of the rotating rod 42 is provided with a threaded connection part 421. The threaded shell 43 is threadedly connected to the outside of the threaded connection part 421 to realize the positioning of the test block positioning module 4. The test block positioning module 4 is inserted with a clamping bar to realize the positioning of the test block inside the splitting fixture 3. The eccentricity elimination module 5 includes a connecting cylinder 51, an alignment connecting vertical rod 52 and a moving ball 53. The top of the lower pressure plate 2 is fixedly connected with two alignment connecting rows 21 corresponding to the eccentricity elimination module 5. The alignment connecting vertical rod 52 and the moving ball 53 are inserted into the alignment connecting rows 21 to realize the positioning of the splitting fixture 3 above the lower pressure plate 2.

[0025] Example

[0026] The test operation control box 1 is fixed to the side of the equipment assembly frame 11. The test operation control box 1 and the equipment assembly frame 11 stand stably on the ground of the test area, which can improve the stability of the device during use. The equipment assembly frame 11 is used to connect other parts of the equipment. The lower pressure plate 2 is fixedly connected inside the equipment assembly frame 11. The lower pressure plate 2 is used to connect and support the splitting clamp 3. The splitting clamp 3 is detachably connected to the top of the lower pressure plate 2, which facilitates the connection, combination and disassembly of the splitting clamp 3 and the lower pressure plate 2.

[0027] Two symmetrically distributed test block positioning modules 4 are rotatably connected inside the left and right side walls of the splitting fixture 3. Each test block positioning module 4 includes a combined vertical plate 41, two rotating rods 42, and two threaded housings 43. The combined vertical plate 41 is rotatably connected to the corresponding side wall of the splitting fixture 3 via the two rotating rods 42. The two rotating rods 42 are symmetrically fixed to the top and bottom of the combined vertical plate 41, one above the other. The other end of the rotating rods 42 is rotatably connected to the splitting fixture 3, achieving a rotatable connection between the combined vertical plate 41 and the splitting fixture 3. This allows the combined vertical plate 41 to rotate inwards and outwards on the corresponding side wall of the splitting fixture 3. The outer wall of the rotating rods 42 is provided with a threaded connection part 421, and the threaded housings 43 are fixedly connected. On the side wall of the splitting fixture 3 corresponding to the rotating rod 42, a threaded housing 43 is sleeved on the outside of the rotating rod 42. The threaded housing 43 is located above the threaded connection part 421. The bottom end of the threaded housing 43 can be threadedly connected to the threaded connection part 421, realizing the connection combination of the threaded housing 43 and the rotating rod 42. The threaded connection between the threaded housing 43 and the threaded connection part 421 enables the positioning work of the combined vertical plate 41 after rotation on the side wall of the splitting fixture 3. A clamping bar can be inserted into the combined vertical plate 41. By inserting the clamping bar into the combined vertical plate 41, the test block placed in the splitting fixture 3 can be positioned inside the splitting fixture 3. The operation is simple and convenient for clamping and positioning the test block placed in the splitting fixture 3.

[0028] The splitting clamp 3 has two linearly distributed arc-shaped side plates 6 slidably connected to its inner side, and two symmetrically distributed combined moving modules 7 fixedly connected to its outer side. The two combined moving modules 7 connect the two arc-shaped side plates 6. Each combined moving module 7 includes two fixed plates 71 and a guide crossbar 72. The two fixed plates 71 are symmetrically fixedly connected to the left and right side walls of the splitting clamp 3, and the guide crossbar 72 is fixedly connected between the two fixed plates 71, located on the outer side of the splitting clamp 3. Two symmetrically distributed connecting seats 61 are fixedly connected to the outer wall of the arc-shaped side plates 6, and the two connecting seats 61 are slidably connected to the outer sides of the two guide crossbars 72, thus realizing the connection between the arc-shaped side plates 6 and the corresponding combined moving modules 7. The connecting combination allows the connecting seat 61 to move along the outer wall of the corresponding guide crossbar 72, enabling the arc-shaped side abutment 6 to move smoothly horizontally along the long side of the splitting clamp 3 inside the splitting clamp 3. This facilitates the adjustment of the position of the arc-shaped side abutment 6 inside the splitting clamp 3. The outer wall of the guide crossbar 72 has several linearly equidistantly distributed spherical grooves 721. The connecting seat 61 has protrusions that fit the spherical grooves 721. The protrusions can smoothly enter the spherical grooves 721 and sequentially enter and exit several spherical grooves 721, improving the stability of the arc-shaped side abutment 6 during positional movement and also serving to position the arc-shaped side abutment 6. The cooperation between the block and the spherical groove 721 provides feedback to the inspector during the adjustment of the position of the arc-shaped side abutment 6, allowing the inspector to simultaneously adjust the position of the two arc-shaped side abutments 6 at the same distance, improving the flexibility and convenience of the inspector's operation. The four test block positioning modules 4, respectively connected to the left and right side walls of the splitting fixture 3, are used to clamp and position the test blocks placed inside the splitting fixture 3. The splitting fixture 3 can accommodate cylindrical test blocks. The combined vertical plate 41 can be adaptively rotated inward and outward on the corresponding side wall of the splitting fixture 3 by two rotating rods 42. The screw-in shell 43 is connected and fixed together with the rotating rods 42 by rotating the screw-in shell 43, thus completing the combination of the vertical plate 41. After rotation, the position is fixed. The two arc-shaped side plates 6 inside the splitting fixture 3 can move horizontally along the long side of the splitting fixture 3, achieving the effect of flexibly adjusting the angle of the combined vertical plate 41 and the position of the arc-shaped side plates 6. The operation is highly convenient. By changing the angle of the combined vertical plate 41, the angle of the clamping bar can be changed. At the same time, the angled clamping bar can be inserted. With the arc-shaped side plates 6 adjusted to be close to the outer wall of the cylindrical test block, the clamping and positioning of the cylindrical test block in the splitting fixture 3 in the vertical and horizontal positions can be flexibly and effectively completed. This achieves the effect of allowing the testing personnel to flexibly and effectively complete the adjustment and positioning of the cylindrical test block in the splitting fixture 3 in the horizontal and vertical positions.

[0029] The bottom of the splitting clamp 3 is fixedly connected to two symmetrically distributed eccentricity elimination modules 5. Each eccentricity elimination module 5 includes a connecting cylinder 51, an aligning connecting vertical rod 52, and a moving ball 53. The connecting cylinder 51 is fixedly connected inside the bottom end of the splitting clamp 3. The aligning connecting vertical rod 52 is slidably connected inside the connecting cylinder 51. The moving ball 53 is rotatably connected inside the bottom end of the aligning connecting vertical rod 52. The top end of the lower pressure plate 2 is fixedly connected to two corresponding aligning connecting rows 21 of the eccentricity elimination modules 5. Each aligning connecting row 21 has four mating cavities with the same diameter as the aligning connecting vertical rod 52. The aligning connecting vertical rod 52 and the moving ball 53 can be inserted into the mating cavities within the aligning connecting row 21, thus achieving the alignment between the aligning connecting vertical rod 52 and the aligning connecting row 21. The connection of 21 enables the splitting clamp 3 to be connected to the lower pressure plate 2, allowing the splitting clamp 3 to be stably placed on top of the lower pressure plate 2, thus achieving the positioning of the splitting clamp 3 above the lower pressure plate 2. Two symmetrically distributed pull plates 22 are inserted inside the lower pressure plate 2, respectively inserted into the two alignment connecting rows 21. The pull plates 22 can block the mating cavities within the alignment connecting rows 21 from above, allowing the moving ball 53 to move above the pull plates 22, achieving the effect of adjusting the eccentricity of the splitting clamp 3. The operator can pull the pull plates 22 outwards to expose the mating cavities at designated positions for positioning the splitting clamp 3 after eccentricity adjustment. The operation is simple. The alignment connecting rod 52 can move into the connecting cylinder 51 fixed at the bottom of the splitting clamp 3, and can also move outward from the connecting cylinder 51. When the inspector places the splitting clamp 3 on the lower pressure plate 2, the moving ball 53 will first contact the lower pressure plate 2. The splitting clamp 3 moves downward, causing the alignment connecting rod 52 to move into the connecting cylinder 51. The moving ball 53 moves at the top of the lower pressure plate 2, allowing the splitting clamp 3 to move smoothly above the lower pressure plate 2. The inspector does not need to push the splitting clamp 3 forcefully to adjust its position above the lower pressure plate 2, which improves the smoothness of the inspector's work when adjusting the position of the splitting clamp 3. The moving ball 53 moves to the corresponding position inside the lower pressure plate 2, and the alignment connecting rod 52 moves outward. After connecting row 21, the inspector pulls the two pull plates 22 outward to expose the mating cavities inside the alignment connecting row 21. This allows the alignment connecting vertical rod 52 and the moving ball 53 to automatically move downward into the mating cavities inside the alignment connecting row 21, completing the positioning of the splitting clamp 3 on the lower pressure plate 2. The operation is highly convenient, eliminating the need for visual observation and forceful pushing by the inspector to align the splitting clamp 3. The four mating cavities inside the alignment connecting row 21 are distributed from front to back. These four cavities, in conjunction with the eccentricity elimination module 5, can adjust the eccentricity of the splitting clamp 3. Through the cooperation of the four cavities and the alignment connecting vertical rod 52, the eccentricity adjustment and subsequent positioning of the splitting clamp 3 can be achieved.This achieves the effect of enabling testing personnel to quickly complete the alignment, eccentricity adjustment, and positioning of the splitting fixture 3, improving the flexibility and efficiency of the device. It effectively adjusts eccentricity to eliminate eccentric pressure, and by changing the eccentricity, different experimental data can be obtained, thus improving testing accuracy and operational convenience.

[0030] The top of the splitting fixture 3 is detachably connected to an upper pad 31, which serves to press the test block from above. The inner walls on both the left and right sides of the splitting fixture 3 are provided with clearance receiving grooves 32. The width of the clearance receiving grooves 32 is greater than the width of the arc-shaped side abutment plate 6. The arc-shaped side abutment plate 6 and the connecting seat 61 can be completely inserted into the corresponding clearance receiving grooves 32, achieving the effect of accommodating the arc-shaped side abutment plate 6 and the connecting seat 61, so as to ensure the smooth placement and positioning of the test block.

[0031] The working principle of this invention is as follows: A cylindrical test block is placed inside the splitting fixture 3. A clamping rod is inserted into the combined vertical plate 41, and the upper pad 31 is inserted into the splitting fixture 3. The upper pad 31 abuts against the outer wall of the cylindrical test block from above to position the cylindrical test block inside the splitting fixture 3. The inspector holds the splitting fixture 3 and places it on the lower pressure plate 2. The moving ball 53 first contacts the lower pressure plate 2, and the splitting fixture 3 moves downward, causing the alignment connecting vertical rod 52 to be pressed and move into the connecting cylinder 51. The inspector moves the splitting fixture 3, and the moving ball 53 moves under the lower pressure plate 2. The top of plate 2 moves smoothly, allowing the splitting clamp 3 to move smoothly above the lower pressure plate 2. After the moving ball 53 moves to the corresponding position of the alignment connecting row 21 inside the lower pressure plate 2, the inspector pulls the two pull plates 22 outward to expose the mating cavity inside the alignment connecting row 21. The alignment connecting vertical rod 52 and the moving ball 53 automatically move downward into the mating cavity inside the alignment connecting row 21, completing the positioning of the splitting clamp 3 on the lower pressure plate 2 and completing the eccentric alignment adjustment of the splitting clamp 3. Then, the inspector conducts the test by operating the test operation control box 1.
