Description

Technical Field

[0001] The invention relates to the technical field of engineering quality inspection equipment, in particular to a core cutting and sampling device for engineering quality inspection. Background Art

[0002] As the scale of domestic engineering construction continues to expand, the importance of engineering quality inspection has become increasingly prominent. As a key link in obtaining accurate inspection data, the performance of core cutting and sampling equipment directly affects the reliability of inspection results and work efficiency.

[0003] At present, the traditional core cutting and sample preparation devices used in engineering quality inspection in my country have a series of problems that need to be solved. On the one hand, the traditional cooling method often adopts a fixed flow water spray mode, which cannot adjust the water spray volume according to the change of cutting frequency. When the cutting frequency is low, continuous large-scale water spraying will cause a waste of water resources; when the cutting frequency is high, the fixed water spray volume cannot meet the demand for sufficient cooling, resulting in excessively high temperatures of the cutting blade and sample, affecting the cutting quality and blade life.

[0004] On the other hand, when it comes to dust treatment, most devices simply collect the dust and lack an efficient dust collection mechanism synchronized with the cutting process, which causes dust to permeate the working environment, which not only endangers the health of the operators, but may also cause wear and damage to other parts of the equipment.

[0005] In order to solve these problems, the present invention proposes a core cutting and sampling device for engineering quality inspection with a same-frequency heat dissipation and water spraying function, which can synchronously adjust the cooling and dust reduction effects according to the cutting frequency, effectively improve the efficiency and quality of core cutting and sampling, and reduce resource waste and environmental pollution. It is of great significance to improving the level of engineering quality inspection in my country and promoting the high-quality development of the engineering construction industry. Summary of the invention

[0006] The present invention is intended to provide a core cutting and sample preparation device for engineering quality inspection. The present invention solves the problem that the traditional cooling method often adopts a fixed flow water spray mode and cannot adjust the water spray volume according to the change of cutting frequency. When the cutting frequency is low, continuous large-scale water spraying will cause a waste of water resources; when the cutting frequency is high, the fixed water spray volume cannot meet the demand for sufficient cooling, resulting in excessively high temperatures of the cutting blade and the sample, affecting the cutting quality and blade life. At the same time, for the treatment of dust by traditional devices, most devices simply collect it, lacking an efficient dust collection mechanism synchronized with the cutting process, causing dust to permeate the working environment, which not only endangers the health of the operator, but may also cause wear and damage to other parts of the equipment. The purpose is to provide an efficient device for engineering quality inspection that integrates cutting, dust removal, cooling and waste collection.

The inner wall of the machine body 1 is fixedly installed with a support plate 5, and the support plate 5 is fixed to the inner wall of the machine body 1 to provide a stable support platform for the placement device 6 to ensure that the placement device 6 remains stable during the cutting operation, and the placement device 6 is fixedly installed above the support plate 5, and the placement device 6 includes a fixed support plate 5. The placing plate 601 above the support plate 5 has placing telescopic rods 602 symmetrically installed on both sides of the placing plate 601, and a placing pressing plate 603 is fixedly installed on one side of the placing telescopic rod 602. The placing pressing plate 603 is adapted to the placing plate 601. The placing plate 601 is located above the supporting plate 5 and is a platform for placing samples to be cut. The placing telescopic rods 602 are symmetrically arranged on both sides of the placing plate 601, and the placing pressing plate 603 at one end thereof can be raised and lowered under the operation of the control device. When in use, the placing telescopic rods 602 are first extended and retracted by the control device to drive the placing pressing plate 603 to rise, so as to facilitate placing the samples to be cut into the placing plate 601; then, the placing telescopic rods 602 are controlled to contract to make the placing pressing plate 603 descend and contact with the placing plate 601 to squeeze and fix the samples.To ensure that the sample does not move during the cutting process, thereby ensuring the cutting accuracy and safety, the collecting device 7 is symmetrically installed on both sides of the placing device 6, and the collecting device 7 includes a hydrophobic plate 701 symmetrically installed at both ends of the supporting plate 5, and a collecting box 702 is movably installed at one end of the hydrophobic plate 701. The hydrophobic plate 701 is symmetrically installed at both ends of the supporting plate 5 and is inclined. After the cutting is completed, the waste sample to be tested can roll into the collecting box 702 along the hydrophobic plate 701, which not only reduces the pollution of the waste to the environment, but also facilitates centralized collection and treatment, and improves work efficiency and environmental friendliness. A dust filter 8 is fixedly installed on the inner wall of the body 1; When in use, first turn on the control device to control the placement telescopic rod 602 to extend, drive the placement pressure plate 603 to rise, and then place the sample to be cut on the placement plate 601. Then, the control device controls the placement telescopic rod 602 to contract, so that the placement pressure plate 603 descends until the placement pressure plate 603 is in close contact with the placement plate 601, and the sample to be cut is firmly squeezed to fix its position to avoid movement in subsequent cutting operations, which affects the cutting quality and accuracy. Then, start the control device to start the bidirectional motor 201 to start running, and the bidirectional motor 201 drives the first transmission gear 202 and the second transmission gear 203 to rotate. The first transmission gear 202 drives the first driven gear 207 to rotate through the active transmission belt 206, thereby driving The cutting blade 208 rotates, and at the same time, pressure is applied to the armrest 209, and the armrest 209 drives the cutting blade 208 to descend until it contacts the object to be cut, and the cutting operation begins. In this process, the cutting blade 208 can effectively cut the sample under the compound movement of rotation and descent. During the operation of the bidirectional motor 201, the second transmission gear 203 drives the circulating transmission belt 303 to rotate the circulating transmission gear 302, thereby driving the double-headed pump 301 to operate. The double-headed pump 301 draws water from the water accumulation chamber 101 through the water inlet pipe 305, and sprays the water on the contact position between the sample to be cut and the cutting blade 208 through the water outlet pipe 304. Since the operation of the double-headed pump 301 is associated with the operation of the bidirectional motor 201, the sprayed water source The amount can be automatically adjusted according to the intensity and duration of the cutting operation, avoiding unnecessary waste of water. The sprayed water will flow down along the cutting position, be collected by the hydrophobic plate 701 and flow back to the water accumulation chamber 101 to form a recycling method. When the returned water enters the water accumulation chamber 101, it will pass through the dust filter 8, which can effectively block impurities and dust in the water, and prevent these debris from entering the circulation system during the circulation process, causing blockage or damage to equipment parts. When the circulation device 3 is running, the water flow drives the impeller 307 to rotate, thereby synchronously controlling the operation of the dust collection device 4 according to the spraying frequency of the circulation device 3, and the rotation of the impeller 307 drives the circulation gear 308 to rotate, and transmits power to the dust collection gear 403 through the circulation belt 309, and the dust collection gear 403 drives The dust suction fan 404 rotates to generate suction, and the dust suction fan 404 sucks the dust generated during the cutting process into the dust suction box 401. The dust is blocked by the dustproof net 405 in the dust suction box 401 and finally falls into the dust collection box 407 in the dust collection box 406, so that it can be dusted according to the frequency of the cutting device 2, reducing energy waste while better collecting the flying dust generated by the cutting. The dust collection box 407 can be easily removed and replaced, which is convenient for centralized treatment of dust. After the cutting is completed, the pressure on the armrest 209 is cancelled, and the reset device 9 starts to work. The reset telescopic rod 903 resets the transmission component above the cutting blade 208 through the cooperation of the reset shaft 902 and the reset plate 901, so that it is out of the cutting position and ready for the next cutting operation.

[0023] Working principle: When using the core cutting sample preparation device, firstly, the control device is used to control the placement telescopic rod 602 to extend and retract to drive the placement pressing plate 603 to rise, and the sample to be cut is placed on the placement plate 601. Then, the control device is used to control the placement telescopic rod 602 to extend and retract to lower the placement pressing plate 603 so that the placement pressing plate 603 contacts the placement plate 601, and the sample to be cut is squeezed and fixed to prevent the sample from moving. Then, the control device is used to control the operation of the bidirectional motor 201, and the operation of the bidirectional motor 201 drives the cutting device 2 and the circulation device 3 to operate. The operator moves the handrail 209. The pressure is applied to make the handrail 209 drive the cutting blade 208 to descend and contact the object to be cut for cutting. After the cutting is completed, the pressure on the handrail 209 is removed, and the resetting device 9 drives the cutting blade 208 to reset and disengage from the top through the resetting telescopic rod 903. During the operation of the bidirectional motor 201, the second transmission gear 203 rotates, and the circulating transmission gears 302 at both ends of the double-headed pump 301 are driven to rotate through the active transmission belt 206, thereby driving the double-headed pump 301 to operate. The double-headed pump 301 extracts the water source in the water accumulation chamber 101 through the water inlet pipe 305, and discharges the water through the water outlet pipe 30 4. Spray water on the contact position between the sample to be cut and the cutting blade 208 to reduce temperature and dust. At the same time, the sprayed water is recovered into the water accumulation chamber 101 through the hydrophobic plate 701 for recycling. The recovered water passes through the dust filter 8 to filter the impurities and dust in the water to prevent clogging of debris during the circulation process. Due to the operation of the circulation device 3, the water in the water accumulation chamber 101 is driven to pass through the water inlet pipe 305. The circulation sleeve 306 is installed on the surface of the water inlet pipe 305. The impeller 307 is movably installed at one end of the circulation sleeve 306. When the water passes through the impeller 307 and enters the water inlet pipe 305, The impeller 307 is driven to rotate, and the rotation of the impeller 307 drives the circulating gear 308 fixedly installed on one side to rotate. The circulating gear 308 drives the dust suction gear 403 at one end to rotate through the circulating belt 309 meshing on the surface. The dust suction gear 403 drives the dust suction fan 404 to rotate. The dust suction fan 404 absorbs the dust generated during the cutting process and collects it in the dust collection box 407. Finally, the two ends of the cut sample to be tested are rolled into the collection box 702 through the inclined hydrophobic plate 701, which reduces environmental pollution and facilitates the collection of waste samples to be tested after cutting.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
