Description

Cement mortar vibration compaction device Technical Field

[0001] This utility model relates to the field of cement mortar compaction technology, and in particular to a cement mortar compaction device. Background Technology

[0002] The cement mortar vibratory compaction device is a key piece of equipment in cement strength testing, mainly used for the preparation and compaction of cement mortar specimens. This device typically consists of a vibrating component, a frame, and a programmable control system. It automatically counts and controls the number of vibrations to ensure the uniformity and consistency of the specimens. The fixing mechanism is a crucial component of the cement mortar vibratory compaction device; it securely fixes the specimen mold to the device to prevent it from moving or falling off during vibration.

[0003] With the continuous advancement of technology and increasingly stringent standards in the cement industry, the requirements for cement mortar compaction devices and their fixing mechanisms are also becoming more stringent. Traditional fixing mechanisms may employ simple locking devices, such as hooks, but these devices may experience poor locking performance due to wear or improper operation during use, thus affecting the compaction quality of the specimens. Therefore, improving and optimizing the fixing mechanism is particularly important.

[0004] Therefore, a cement mortar compaction device is proposed. Summary of the Invention

[0005] In order to improve the problem that the existing cement mortar compaction device has poor locking effect when fixing the mold, and the specimen is not firmly fixed, thus affecting the compaction quality of the specimen, this utility model provides a cement mortar compaction device.

[0006] This utility model provides a cement mortar compaction device, which adopts the following technical solution:

[0007] A cement mortar compaction device includes a body, a vibrating plate, a fixing mechanism, and a pressing mechanism. The vibrating plate is located on the top of the body. The fixing mechanism includes a placement plate fixedly installed on the vibrating plate, two transverse clamping plates symmetrically installed on the placement plate, and two longitudinal clamping plates symmetrically installed on the transverse clamping plates.

[0008] The clamping mechanism includes a pressure frame hinged to the vibrating plate. One end of the pressure frame is fixedly connected to a connecting ear, and one end of the connecting ear is provided with a locking groove. A fixing block is fixedly connected to one side of the top of the vibrating plate. A stud is hinged inside the fixing block, and a locking nut is threaded onto the stud.

[0009] By adopting the above technical solution and setting the fixing mechanism, the four sides of the test mold can be effectively fixed, making the fixing of the test mold more comprehensive and thus improving the fixing effect of the test mold. With the setting of the clamping mechanism, after the four sides of the test mold are fixed by the fixing mechanism, the pressure frame can be rotated and pressed on the top of the test mold. Finally, the connecting ear will be driven by the pressure frame to press against the fixing block. Then, the stud can be rotated to a vertical position so that the stud passes through the locking groove of the connecting ear. Then, the locking nut is rotated so that the locking nut slides down along the stud and presses against the connecting ear to press against the fixing block. The top of the test mold can be pressed by the pressure frame, which further improves the locking effect of the test mold and ensures the compaction quality.

[0010] Optionally, a first bidirectional screw arranged laterally is rotatably mounted inside the placement plate, and two transverse clamps are respectively sleeved on both sides of the first bidirectional screw and threadedly connected to the first bidirectional screw. A first knob is fixedly connected to one end of the first bidirectional screw.

[0011] By adopting the above technical solution, rotating the first knob causes the first bidirectional screw to rotate, which in turn causes the two transverse clamping plates to slide, bringing them closer together and clamping and fixing the two sides of the test mold laterally.

[0012] Optionally, the top surface of the placement plate is provided with a sliding groove, and both ends of the transverse clamp slide within the sliding groove.

[0013] By adopting the above technical solution, the transverse clamp can be guided and limited, thereby improving the stability of the transverse clamp.

[0014] Optionally, a second bidirectional screw arranged longitudinally is rotatably mounted inside the transverse clamping plate. The two longitudinal clamping plates are respectively sleeved on both sides of the second bidirectional screw and threadedly connected to the second bidirectional screw. A second knob is fixedly connected to one end of the second bidirectional screw.

[0015] By adopting the above technical solution, rotating the second knob causes the second bidirectional screw to rotate, which in turn causes the two longitudinal clamping plates to slide along the transverse clamping plate, bringing the two longitudinal clamping plates closer to each other and longitudinally clamping and fixing the other two sides of the test mold.

[0016] Optionally, butterfly blocks are provided on both sides of the locking nut.

[0017] By adopting the above technical solution and using the butterfly block, the locking nut can be easily rotated manually.

[0018] Optionally, the bottom of the locking nut abuts against an elastic pad.

[0019] By adopting the above technical solution and setting the elastic pad, an elastic shock absorption effect can be achieved, making the contact between the locking nut and the connecting lug more stable.

[0020] Optionally, the top of the machine body is hinged with a protective cover for covering the vibration plate, and the protective cover is fixed to the machine body by a buckle.

[0021] By adopting the above technical solution and setting up a protective cover, the working area of ​​the test mold can be covered and protected.

[0022] Optionally, sound-insulating cotton is fixedly connected inside the protective cover.

[0023] By adopting the above technical solution and installing sound-insulating cotton, the interior of the protective cover can be soundproofed, reducing noise pollution generated during vibration.

[0024] In summary, this utility model has the following beneficial effects:

[0025] 1. This utility model, through the setting of a fixing mechanism, when fixing the test mold, places the test mold on the placement plate, and then first rotates the first knob, causing the first double-direction screw to rotate. The first double-direction screw causes the two transverse clamping plates to slide along the slide groove, bringing the two transverse clamping plates closer together and clamping and fixing the two sides of the test mold laterally. Then, rotates the second knob, causing the second double-direction screw to rotate. The second double-direction screw causes the two longitudinal clamping plates to slide along the transverse clamping plates, bringing the two longitudinal clamping plates closer together and clamping and fixing the other two sides of the test mold longitudinally. Thus, the test mold can be effectively fixed on all four sides, making the fixing of the test mold more comprehensive and improving the fixing effect of the test mold.

[0026] 2. This utility model, through the setting of a clamping mechanism, after the test mold is fixed around its perimeter by a fixing mechanism, can rotate a pressure frame to press on top of the test mold. Finally, the connecting ear will abut against the fixing block under the action of the pressure frame. Then, the stud can be rotated to a vertical position so that the stud passes through the locking groove of the connecting ear. Then, the locking nut can be rotated so that the locking nut slides down along the stud and abuts against the connecting ear, pressing the connecting ear against the fixing block. This allows the top of the test mold to be clamped by the pressure frame, further improving the locking effect of the test mold and ensuring the compaction quality. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to Figures 1-4 of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please refer to Figures 1-2. The cement mortar compaction device includes a body 1, a vibrating plate 2, a fixing mechanism 3, and a pressing mechanism 4. The vibrating plate 2 is located on the top of the body 1. A protective cover 11 for covering the vibrating plate 2 is hinged to the top of the body 1. The protective cover 11 is fixed to the body 1 by a buckle. The protective cover 11 can cover and protect the working area of ​​the test mold. Sound insulation cotton 12 is fixedly connected inside the protective cover 11. The sound insulation cotton 12 can play a sound insulation role inside the protective cover 11, reducing noise pollution generated during vibration.

[0035] Referring to Figures 3 and 4, the fixing mechanism 3 includes a placement plate 31 fixedly mounted on the vibrating plate 2, two transverse clamping plates 32 symmetrically mounted on the placement plate 31, and two longitudinal clamping plates 33 symmetrically mounted on the transverse clamping plates 32. A first bidirectional screw 34 arranged transversely is rotatably mounted inside the placement plate 31. The two transverse clamping plates 32 are respectively sleeved on both sides of the first bidirectional screw 34 and threadedly connected to it. A first knob 35 is fixedly connected to one end of the first bidirectional screw 34. A groove 36 is provided on the top surface of the placement plate 31, and both ends of the transverse clamping plates 32 slide within the groove 36. The groove 36 guides and limits the ends of the transverse clamping plates 32, improving their stability. A second bidirectional screw 37 arranged longitudinally is rotatably mounted inside the transverse clamping plates 32, and the two longitudinal clamping plates 33 are respectively sleeved on the second bidirectional screw 37. Both sides are threadedly connected to the second bidirectional screw 37. One end of the second bidirectional screw 37 is fixedly connected to the second knob 38. Through the setting of the fixing mechanism 3, when fixing the test mold, the test mold is placed on the placement plate 31. Then, the first knob 35 is rotated first, so that the first knob 35 drives the first bidirectional screw 34 to rotate. The first bidirectional screw 34 drives the two transverse clamping plates 32 to slide along the slide groove 36, so that the two transverse clamping plates 32 move closer to each other and clamp and fix the two sides of the test mold laterally. Then, the second knob 38 is rotated, so that the second knob 38 drives the second bidirectional screw 37 to rotate. The second bidirectional screw 37 drives the two longitudinal clamping plates 33 to slide along the transverse clamping plates 32, so that the two longitudinal clamping plates 33 move closer to each other and clamp and fix the other two sides of the test mold longitudinally. Thus, the test mold can be effectively fixed on all four sides, making the fixation of the test mold more comprehensive and improving the fixation effect of the test mold.

[0036] Referring to Figures 3 and 4, the clamping mechanism 4 includes a clamping frame 41 hinged to the vibrating plate 2. One end of the clamping frame 41 is fixedly connected to a connecting ear 42, and one end of the connecting ear 42 has a locking groove 43. A fixing block 44 is fixedly connected to one side of the top of the vibrating plate 2. A stud 45 is hinged inside the fixing block 44, and a locking nut 46 is threaded onto the stud 45. With the clamping mechanism 4, after the mold is fixed around the perimeter by the fixing mechanism 3, the clamping frame 41 can be rotated to press against the mold. Finally, the connecting ear 42 will be pressed against the fixed block 44 by the pressure frame 41. Then, the stud 45 can be rotated to a vertical position so that the stud 45 passes through the locking groove 43 of the connecting ear 42. Then, the locking nut 46 is rotated so that the locking nut 46 slides down along the stud 45 and presses against the connecting ear 42 to press it against the fixed block 44. The pressure frame 41 can then press the top of the test mold, further improving the locking effect of the test mold and ensuring the compaction quality.

[0037] Furthermore, both sides of the locking nut 46 are provided with butterfly blocks 47, which facilitates manual rotation of the locking nut 46. The bottom of the locking nut 46 abuts against an elastic pad 48, which provides elastic shock absorption and makes the contact between the locking nut 46 and the connecting lug 42 more stable.

[0038] The implementation principle of this utility model is as follows: During operation, first loosen the buckle of the fixed protective cover 11, then flip and open the protective cover 11. When fixing the test mold, place the test mold on the placement plate 31. Then, first rotate the first knob 35, causing the first knob 35 to drive the first bidirectional screw 34 to rotate. The first bidirectional screw 34 drives the two transverse clamping plates 32 to slide along the slide groove 36, so that the two transverse clamping plates 32 move closer to each other, and horizontally clamp and fix the two sides of the test mold. Then, rotate the second knob 38, causing the second knob 38 to drive the second bidirectional screw 37 to rotate. The second bidirectional screw 37 drives the two longitudinal clamping plates 33 to slide along the transverse clamping plates 32, so that the two longitudinal clamping plates 33 move closer to each other, and vertically clamp and fix the other two sides of the test mold. This ensures that the test mold is effectively fixed on all four sides, making the fixation of the test mold more comprehensive and improving the fixation effect of the test mold. After the test mold is fixed on all four sides by the fixing mechanism 3, the pressure frame can be rotated. 41 is pressed on top of the test mold. Finally, the connecting ear 42 will abut against the fixing block 44 under the action of the pressure frame 41. Then, the stud 45 can be rotated to a vertical position so that the stud 45 passes through the locking groove 43 of the connecting ear 42. Then, the locking nut 46 is rotated by the butterfly block 47 so that the locking nut 46 slides down along the stud 45 and abuts against the connecting ear 42, pressing the connecting ear 42 against the fixing block 44. The elastic pad 48 can play an elastic shock absorption role, making the contact between the locking nut 46 and the connecting ear 42 more stable. The pressure frame 41 can then press the top of the test mold, further improving the locking effect of the test mold and ensuring the compaction quality. After the test mold is fixed, the protective cover 11 can be flipped over to cover the test mold and fixed with buckles to cover and protect the working area. The sound insulation cotton 12 can play a sound insulation role inside the protective cover 11, reducing noise pollution generated during vibration.
