Description

Technical Field

[0001] The utility model relates to the technical field of cement production detection, in particular to a screw removing mechanism. Background Art

[0002] Cement is a common building material that is made from limestone, clay and other materials that have been calcined and ground. Cement is widely used in the construction industry to make concrete, mortar and other building structures. It has good adhesion and durability, and can solidify and harden to form a strong structure. The main components of cement are limestone and clay, which are calcined at high temperatures to form clinker. The clinker is ground into a fine powder together with an appropriate amount of gypsum to form the final cement product. There are many varieties of cement, the most common ones are Portland cement, sulphoaluminate cement and ordinary Portland cement. Cement is widely used in construction. It can be used to build various projects such as houses, bridges, roads, tunnels, etc. Cement can be mixed with sand, gravel and water to form concrete, which is used to cast structures such as foundations, columns, beams and floor slabs. Cement can also be used with mortar for bricklaying, plastering and repair work.

[0003] Cement raw meal is a material that is ground to a certain fineness by mixing lime raw materials, clay raw materials and a small amount of correction raw materials (sometimes mineralizers, crystal seeds, etc. are added, and coal is added during vertical kiln production) in proportion. In the cement production process, it is necessary to control the products of each link to ensure that the quality of the final cement product meets the requirements. The higher the decomposition rate of cement raw meal, the higher the heat exchange efficiency of the kiln tail preheater and the better the working condition of the decomposition furnace. Therefore, the decomposition rate of raw meal entering the kiln is an important indicator for evaluating the working effect of the pre-decomposition furnace system, and it is also an important parameter for production control. Therefore, obtaining hot raw meal is the primary link of analysis and control.

[0004] The mortar test mold is a mold used to prepare cement mortar specimens. In cement engineering, in order to test the performance of cement mortar, it is often necessary to prepare standardized specimens for experiments. The molds used to prepare these cement mortar specimens are called mortar test molds.

Therefore, they cannot be understood as limitations on the present invention.

[0028] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0029] Since the existing mortar test mold is usually an integral structure, the various components are usually connected by fastening bolts or fastening screws, which makes disassembly difficult. In addition, operators often use the inverted method to take out the test piece during the sampling process, which often affects the quality of the test piece and thus affects the user experience.

[0030] In order to solve the above technical problems, Figures 1 to 7As shown, a screw removal mechanism in this embodiment is mainly used to disassemble the mortar test mold 3. Specifically, the mortar test mold 3 includes a test mold base 3-1 and an upper mold 3-2, that is, the test mold base 3-1 and the upper mold 3-2 are separated. In order to adapt to the above-mentioned screw removal mechanism, the above-mentioned trial mold base 3-1 in this embodiment has a base body 3-1-1, one end of the above-mentioned base body 3-1-1 has a stopper 3-1-2, the other end of the above-mentioned base body 3-1-1 has a connecting seat 3-1-3, the above-mentioned connecting seat 1-3 is provided with a connecting hole 3-1-4, the above-mentioned upper mold 3-2 is installed on the above-mentioned base body 3-1-1, and the above-mentioned upper mold 3-2 is fixed between the above-mentioned stopper 3-1-2 and the above-mentioned connecting seat 3-1-3 by passing the above-mentioned locking member 3-3 through the above-mentioned connecting hole 3-1-4, that is, the above-mentioned trial mold base 3-1 and the upper mold 3-2 are connected by only one locking member 3-3, specifically, the above-mentioned locking member 3-3 can be a locking bolt, and the above-mentioned connecting hole 3-1-4 is a threaded hole, the threaded hole can be tightly matched with the locking bolt to provide a firm connection, thereby ensuring the safety and stability between the connecting seat 3-1-3 and the locking member 3-3. The threaded connection is convenient for disassembly and replacement, which is beneficial for future maintenance and repair work, and is convenient for disassembly and assembly of the upper mold 3-2, reducing the difficulty of disassembly and assembly. The threaded hole can be adjusted as needed, so that the position and angle of the locking bolt can be flexibly changed according to the position of the upper mold 3-2, thereby improving applicability and adjustability. The screw removal mechanism in this embodiment includes a screw removal machine 1 and a screw removal machine base 2. In order to facilitate the replacement or maintenance of the screw removal base 2, the screw removal machine 1 is installed on the screw removal machine base 2 in a detachable manner such as bolt connection or clamping.

[0031] In order to ensure the stability of the screw remover 1 during operation, the structure and shape of the screw remover base 2 are adapted to the structural shape of the bottom of the screw remover 1, that is, the bottom of the screw remover 1 can be arranged to fit the upper surface of the screw remover base 2, and then a base connection hole 2-1 and a base connection hole 2-2 are provided on the screw remover base 2, and a locking bolt is passed through the base connection hole 2-1 to realize the fixed connection between the screw remover base 2 and the screw remover 1, and a locking bolt is passed through the base connection hole 2-1 to realize the connection between the screw remover base 2 and the bottom substrate 4, and many other devices are also installed on the substrate 4 to realize automatic mold removal. For ease of operation, the base connection hole 2-2 is located inside the base connection hole 2-1, that is, after the screw remover 1 is installed on the screw remover base 2, the screw remover mechanism is installed as a whole on the substrate 4, thereby ensuring the stability of the overall structure. In order to prevent the locking bolt from affecting other components on the screw removing mechanism, the base connecting hole 1 2-1 and the base connecting hole 2-2 are both countersunk holes, and the countersunk directions of the two are exactly opposite, that is, the base connecting hole 1 2-1 is countersunk downward from the top of the screw removing machine base 2, and the base connecting hole 2-2 is countersunk upward from the bottom of the screw removing machine base 2, so that the operator can operate and quickly install the screw removing machine base 2.

[0032] The screw removing machine 1 in this embodiment includes a linear module 1-1, a connecting slider 1-3, a driving motor 1-4, a transmission shaft 1-5 and a screwdriver head 1-6.

In order to ensure the transmission effect, the transmission shaft 1-5 is installed at the output end of the driving motor 1-4 and is used to connect the driving motor 1-4 and the screwdriver head 1-6. The screwdriver head 1-6 is adapted to the locking member 3-3 and is used to remove the locking member 3-3. The locking member 3-3 is a locking screw or a locking bolt, which mainly needs to be adapted to the screwdriver head 1-6.

[0033] In order to ensure the docking rate between the screwdriver head 1-6 and the locking piece 3-3, and thus improve the disassembly efficiency, a protective sleeve 1-7 is provided on the outer periphery of the screwdriver head 1-6, and the screwdriver head 1-6 is embedded in the protective sleeve 1-7. The protective sleeve 1-7 also plays a role of pre-positioning in this process, that is, the locking piece 3-3 first contacts the protective sleeve 1-7, and then locks on the screwdriver head 1-6 in the protective sleeve 1-7, and starts the drive motor 1-4, and drives the transmission shaft 1-5 through the drive motor 1-4, and then drives the screwdriver head 1-6 to rotate, thereby realizing the disassembly of the locking piece 3-3. The central axis of the protective sleeve 1-7 is located on the same straight line as the central axis of the screwdriver head 1-6. Furthermore, the central axis of the protective sleeve 1-7, the central axis of the screwdriver head 1-6 and the central axis of the transmission shaft 1-5 are located on the same straight line. The central axes of the three are aligned, which can more effectively transmit force, so that the screwdriver head 1-6 can turn the screw more stably, which helps to reduce damage or slippage caused by torsional force. In this embodiment, by aligning the central axes of the components, the accuracy of the operation can be improved, so that the screwdriver head 1-6 can more easily enter the screw hole and correctly align the screw. The alignment of the central axes also helps to maintain the stability of the tool and reduce damage or errors caused by unstable operation.

[0034] In order to further ensure the stability of the transmission shaft 1-5 during the transmission process and reduce the probability of the transmission shaft 1-5 shaking during the rotation process, a support seat 1-8 is installed between the above-mentioned connecting slider 1-3 and the above-mentioned drive motor 1-4, which is mainly used to support the above-mentioned transmission shaft 1-5 and facilitate the installation of the above-mentioned drive motor 1-4. The above-mentioned support seat 1-8 in this embodiment includes a main support base plate 1-8-1 in a flat plate shape, and the main support base plate 1-8-1 and the connecting slider 1-3 are detachably connected by opening threaded holes and penetrating locking bolts, which is convenient for the later inspection and maintenance of the screw removal mechanism. The main support base plate 1-8-1 is provided with a support plate 1-8-2 and a support plate 2 1-8-3 for supporting the transmission shaft 1-5. The support plate 1 1-8-2, the support plate 2 1-8-3 and the main support base plate 1-8-1 are arranged perpendicular to each other, and the support plate 1 1-8-2 and the support plate 2 1-8-3 are arranged parallel to each other. Through holes for the transmission shaft 1-5 to pass through are provided on the support plate 1 1-8-2 and the support plate 2 1-8-3. The support plate 1 1-8-2 is arranged close to one end of the transmission shaft 1-5, i.e., the end closer to the drive motor 1-4, and the support plate 2 1-8-3 is arranged close to the other end of the transmission shaft 1-5, i.e., close to the screwdriver head 1-6. In order to enhance the structural strength of the support seat 1-8 itself, two reinforcing plates 1-8-4 in a triangular shape are arranged on the side of the support plate 1 1-8-2, and the two reinforcing plates 1-8-4 are arranged at a distance.

[0035] Due to the viscosity of cement mortar, the test mold and the sample sometimes stick together, making it difficult to remove the sample. The screw removal mechanism in this embodiment, i.e., the test mold base 3-1 and the upper mold 3-2, are usually made of metal or plastic. The metal test mold is usually made of cast iron or steel, has high wear resistance and stability, and is suitable for long-term use. The plastic test mold is usually made of polymer material, has good anti-sticking and formability, and is suitable for one-time or short-term use. The user can choose a suitable test mold according to the needs.

[0036] A screw removing mechanism in the present embodiment has an ingenious structure. By setting up a screw removing machine 1, the mortar test mold 3 can be automatically disassembled without manual disassembly, which reduces the labor intensity of the operator and improves the disassembly efficiency, enhances the user experience, and is conducive to the promotion and application of the above-mentioned screw removing mechanism in the market.
