Description

Technical Field

[0001] This utility model relates to the technical field of concrete experimental equipment, and in particular to a cement mortar vibration table. Background Technology

[0002] The cement mortar vibration table is one of the core pieces of equipment in the process of preparing cement strength test samples. It mainly consists of a vibrating component, a frame, and a proximity switch control system. The working principle of the equipment is as follows: a synchronous motor drives a cam to rotate, which in turn drives the vibrating component to move upward. After the vibrating component rises to a set height, it falls freely. The resulting vibration compacts the cement mortar in the mold under impact force, thus providing standard specimens for subsequent cement strength testing.

[0003] Specifically, the operation procedure of the cement mortar vibration table is usually as follows: First, fix the empty mold and mold sleeve on the platform of the vibration table. Then, use a spoon to directly pour the cement mortar into the mold in two layers from the mixing pot. When pouring the first layer of cement mortar, the material layer needs to be leveled after the cement mortar is put in. Then, start the equipment to vibrate 60 times. After the first layer is vibrated, pour in the second layer of cement mortar, level the material layer again and vibrate 60 times. Finally, remove the mold to complete the sample preparation.

[0004] However, existing cement mortar vibratory compaction tables have significant shortcomings in the material layer leveling process: currently, the industry generally uses a manual method for leveling, requiring workers to use tools such as brushes and scrapers to level the cement mortar in the three grooves of the mold sequentially. This method is not only cumbersome, time-consuming, and labor-intensive, but also makes it difficult to guarantee the consistency of manual leveling, easily affecting the quality of the specimens due to differences in human operation; at the same time, the process of leveling groove by groove also reduces the efficiency of the test. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cement mortar compaction table that can quickly and conveniently level the cement mortar in the mold, saving time and effort, while ensuring the quality of the specimen and improving the efficiency of the test.

[0006] To achieve the above objectives, this utility model provides a cement mortar vibration table, including a frame, a vibration mechanism, a platform, and a control system. It also includes a cover plate, a compaction mechanism, and several clamps. The compaction mechanism includes a push plate and several pressure plates. The cover plate is movably mounted on the platform and used to cover the test mold. The push plate and several pressure plates are located on both sides of the cover plate. The push plate is detachably connected to the several pressure plates. The push plate is used to drive the several pressure plates to extend into the test mold to flatten the cement mortar inside the mold. The several clamps are located on both sides of the test mold and used to press the cover plate onto the test mold. Each clamp is detachably equipped with a locking element detachably connected to the push plate.

[0007] Preferably, the compaction mechanism further includes several connecting rods and elastic elements. One end of each of the connecting rods is detachably connected to the push plate, and the other end of each of the connecting rods passes through the cover plate and is detachably connected to the pressure plate. An elastic element is sleeved on the outer wall of each of the connecting rods, and the elastic elements are located between the pressure plate and the cover plate.

[0008] Preferably, the cover plate has several grooves on the side facing the test mold for accommodating several pressure plates.

[0009] Preferably, any of the clamps has a limiting groove extending toward the push plate, and the locking member is detachably installed in the limiting groove. The push plate has an insertion hole for the locking member to extend into.

[0010] Preferably, the push plate and the cover plate are each provided with a handle.

[0011] Preferably, the cover plate is provided with a plurality of supports, and the plurality of supports and the clamp form a placement space for accommodating the test mold. The cover plate is rotatably mounted on the plurality of supports, and a protrusion is formed on the side wall of the cover plate to abut against the test mold.

[0012] Beneficial effects: 1. In the cement mortar vibration table of this utility model, the cover plate can effectively prevent cement mortar from splashing during the vibration process, which reduces the cleaning steps after the test and avoids the impact of cement mortar loss on the quality of the specimen molding.

[0013] 2. During use, the cement mortar vibrating table of this utility model allows the operator to push the push plate towards the mold, thereby completing the flattening operation of all cement mortar in the mold slots in one go. There is no need to use brushes, scrapers, or other tools to level the cement mortar in the mold one by one. This not only significantly shortens the operation time of a single test, saving time and effort, but also avoids the problem of inconsistent mortar layer flatness caused by differences in the force and angle of human operation. It significantly improves the test efficiency and the stability of the specimen quality, and is reliable in use.

[0014] 3. In the cement mortar vibrating table of this utility model, the detachable connection between the locking part and the push plate can not only effectively prevent the push plate from moving due to shaking during vibration, thus avoiding additional compression or disturbance to the already flattened cement mortar layer, but also ensure that the cement mortar layer maintains the preset flatness during the vibration process, significantly improving the stability of the specimen quality.

[0024] Example 1: This utility model proposes a cement mortar vibration compaction table.

[0025] In one embodiment of this utility model, the cement mortar vibration table 100 includes a frame 1, a vibration mechanism 2, a platform 3, and a control system. It also includes a cover plate 4, a compaction mechanism, and several clamps 5. The compaction mechanism includes a push plate 6 and several pressure plates 7. The cover plate 4 is movably mounted on the platform 3 and is used to cover the test mold 200. The push plate 6 and several pressure plates 7 are located on both sides of the cover plate 4. The push plate 6 and several pressure plates 7 are detachably connected. The push plate 6 is used to drive the several pressure plates 7 to extend into the test mold 200 to flatten the cement mortar in the test mold 200. Several clamps 5 are located on both sides of the test mold 200 and are used to press the cover plate 4 onto the test mold 200. The clamps 5 are detachably mounted with locking members 8 that are detachably connected to the push plate 6.

[0026] Specifically, such as Figures 1 to 5As shown, in the cement mortar vibration table 100 of this utility model, the frame 1, vibration mechanism 2, table 3 and control system are all mature technologies. The main vibration mechanism 2 can drive the cam to rotate through a synchronous motor to realize the lifting and vibration of the table 3. The control system can use a proximity switch programmable control system to control the number of vibrations, such as 60 vibrations per vibration, thereby providing basic vibration and control functions for the cement mortar vibration operation. Furthermore, since the cover plate 4 is movably installed on the platform 3, the movable installation method of the cover plate 4 can be a rotating connection, such as using a pin to allow the cover plate 4 to rotate relative to the mold 200. This effectively prevents cement mortar from splashing during the compaction process, reducing the cleaning steps after the test and avoiding the impact of cement mortar loss on the specimen molding quality. At the same time, after the first or second layer of mortar is filled into the mold 200, since the push plate 6 and several pressure plates 7 are located on both sides of the cover plate 4, and the push plate 6 and several pressure plates 7 are detachably connected, the detachable connection method can be a threaded connection, such as using a screw with threads at both ends. This allows the staff to push the push plate 6 towards the mold 200, which in turn moves several pressure plates 7 synchronously toward the mold 200. The number and position of the pressure plates 7 correspond one-to-one with the grooves of the mold 200, thus enabling the flattening of all the cement mortar in the grooves of the mold 200 in one go. This eliminates the need for staff to use brushes, scrapers, or other tools to level the cement mortar in the mold 200 sequentially. This not only significantly shortens the operation time of a single test, saving time and effort, but also avoids the problem of inconsistent mortar layer flatness caused by differences in the force and angle of human operation. It significantly improves the test efficiency and the stability of the specimen quality, making it reliable in use.

[0027] Understandably, since several clamps 5 are located on both sides of the mold 200, the cover plate 4 can be pressed and fixed at multiple points through the clamps 5, thereby ensuring the relative position of the cover plate 4 and the mold 200 is stable during vibration, thus effectively preventing displacement or loosening of the mold 200. The structural design is simple and reasonable. Furthermore, since several clamps 5 are detachably equipped with locking parts 8 that are detachably connected to the push plate 6, the locking parts 8 can be made of pins or the like, and the detachable installation method of the locking parts 8 on the clamps 5 can be threaded connection or sliding groove snap-fit, etc. The detachable connection between the locking parts 8 and the push plate 6 can not only effectively prevent the push plate 6 from shaking and causing the pressure plate 7 to shift during vibration, avoiding additional compression or disturbance to the already flattened cement mortar layer, but also ensure that the cement mortar layer maintains the preset flatness during the compaction process, significantly improving the stability of the specimen quality.

[0028] In one embodiment, the compaction mechanism further includes a plurality of connecting rods 9 and elastic elements 10. One end of each of the connecting rods 9 is detachably connected to the push plate 6, and the other end of each of the connecting rods 9 passes through the cover plate 4 and is detachably connected to the pressure plate 7. An elastic element 10 is sleeved on the outer wall of each of the connecting rods 9, and the elastic elements 10 are all located between the pressure plate 7 and the cover plate 4. Specifically, as shown... Figures 2 to 5 As shown, one end of several connecting rods 9 can be detachably connected to the push plate 6 by a threaded connection, and the other end can be detachably connected to the pressure plate 7 after passing through the cover plate 4 by a threaded connection. Each connecting rod 9 has an elastic element 10 sleeved on its outer wall. The elastic element can be a spring, which has the characteristics of compact structure, easy material sourcing, and large elastic restoring force. This not only achieves a rigid connection between the push plate 6 and the pressure plate 7, ensuring that each pressure plate 7 presses against the mortar layer synchronously and evenly, but also allows the pressure plate 7 to automatically reset to its initial position after the push plate 6 is released by the elastic element 10. This eliminates the need for manual reset, simplifies the operation process, avoids disturbance to the mortar inside the mold 200 during the reset process, further improves the ease of operation and the stability of the specimen quality, and ensures reliable use.

[0029] In one embodiment, the cover plate 4 has a plurality of grooves 11 on the side facing the test mold 200 for accommodating a plurality of pressure plates 7. Specifically, as shown in the figure... Figures 2 to 5 As shown, when there is no need to flatten the cement mortar in the mold 200, the pressure plate 7 can be stored in the groove 11 under the action of the elastic element 10 and the locking element 8. This can effectively prevent the cover plate 4 from rotating or the pressure plate 7 from colliding with the mold 200 and other components during placement, thus extending the service life of the components. At the same time, the groove 11 can limit the pressure plate 7, reduce unnecessary shaking of the pressure plate 7 during vibration, and ensure the alignment accuracy of the pressure plate 7 with the groove of the mold 200 during subsequent flattening operations. The structural design is simple and reasonable.

[0030] In one embodiment, a limiting groove 12 is provided on any of the clamps 5, the limiting groove 12 extends toward the push plate 6, and a locking member 8 is detachably installed in the limiting groove 12. The push plate 6 has an insertion hole 13 for the locking member 8 to extend into. Specifically, as shown... Figures 2 to 5 As shown, the limiting groove 12 provides clearance for the locking member 8 to move toward the push plate 6, and guides the locking member 8 to smoothly and stably engage with the insertion hole 13 on the push plate 6, thereby ensuring that the push plate 6 remains fixed and stationary during vibration, thus effectively preventing the pressure plate 7 from causing additional disturbance to the mortar layer, and significantly improving the consistency of the specimen molding quality.

[0031] In one embodiment, specifically, as Figure 3 and Figure 4As shown, handles 14 are provided on the push plate 6 and the cover plate 4 respectively, so that the staff can push the push plate 6 or rotate it to open or close the cover plate 4. The operation is convenient and the use is simple.

[0032] In one embodiment, a plurality of supports 15 are provided on the cover plate 4, and the plurality of supports 15 and the clamp 5 form a placement space for accommodating the test mold 200. The cover plate 4 is rotatably mounted on the plurality of supports 15, and a protrusion 16 is formed on the side wall of the cover plate 4 to abut against the test mold 200. Specifically, as shown Figures 1 to 4 As shown, the placement space formed by the support 15 and the clamp 5 enables rapid installation and positioning of the test mold 200. For example, the operator can abut the side wall of the test mold 200 against several supports 15 and clamps 5, ensuring the consistency of the test mold 200's placement position each time. This guarantees the alignment accuracy between the pressure plate 7 and the groove of the test mold 200, avoiding flattening deviations caused by the test mold 200's offset. Furthermore, when the operator opens the cover plate 4 to fill cement mortar or remove the test mold 200, the protrusion 16 on the cover plate 4 abuts against the side wall of the test mold 200. This prevents the cover plate 4 from rotating excessively beyond its operating range, thus preventing interference with the operator's handling of the test mold 200 or material loading.

[0033] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
