Description

Technical Field

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

[0002] In engineering quality inspection, the main purpose of core cutting and sampling (usually refers to the processing after core sampling) is to evaluate the internal quality, mechanical properties and defects of materials such as concrete. Through core cutting and sampling, the internal structure of concrete materials can be intuitively observed, such as lattice type (for certain specific materials), mineral composition (for concrete, it is mainly the distribution of materials such as aggregates and cement), bubbles, honeycombs, holes and other defects.

[0003] A Chinese patent application with patent application number CN202010300722.4 discloses a core cutting and sampling equipment for engineering quality inspection. Although this application can prevent the entire sample from sliding when it is cut into a cross section or a section, effectively ensuring the effect of core cutting and sampling, it also realizes intermittent water spraying of the nozzle, and the amount of water sprayed is proportional to the feed speed during the core cutting process. There is no need to use a water pump to pump water, which not only reduces the equipment cost, but also reduces the waste of coolant spraying during the core cutting process, and is more energy-saving and environmentally friendly. However, when this application is put into use, since the workpiece to be cut is cylindrical, when this application is cut, the cylindrical sample is cut and broken when it is cut, and the device cannot synchronously clamp the samples on both sides of the cutting disk during cutting, which makes it easy to cause displacement during subsequent cutting. Improvements are needed to address this problem. Summary of the invention

[0011] According to the above technical solution, the output shaft of the driving motor passes through the front side of the workbench and the front side of the driving seat and extends to the inner side of the driving seat and is fixedly connected to the lead screw 1. The lead screw 1 is rotatably connected to the inner wall of the back side of the driving seat away from the driving motor. A guide rod is arranged inside the driving seat, and the guide rod is located on the left and right sides of the lead screw 1. Guide rings are arranged on the left and right sides of the bottom of the curved bottom plate corresponding to the guide rods. The curved bottom plate is slidably connected to the guide rods through the guide rings, and can be moved and guided by the cooperation of the guide rings and the guide rods when the curved bottom plate moves.

The sample is adsorbed and fixed by setting a negative pressure adsorption plate. Since the negative pressure adsorption plate and the rubber clamping plate are both energy-absorbing materials, the fixed concrete sample can reduce the vibration and impact of the cutting equipment during the cutting process and extend the service life of the equipment.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] For example, see Figure 1-5 The present invention provides a technical solution: a core cutting and sampling device for engineering quality inspection, including a body 1 and a driving assembly 6. A workbench 2 is fixedly connected to the top of the body 1, a driving member 3 is arranged on the top of the back of the body 1, a cutting disc 4 is arranged on the front of the driving member 3, and a driving seat 5 is arranged in the middle of the bottom of the workbench 2.

[0021] Wherein, the driving component 6 comprises: The driving motor 601 is fixedly connected to the middle of the front side of the workbench 2. The driving motor 601 has an output shaft. The output shaft of the driving motor 601 is fixedly connected to a lead screw 602. The outer side of the lead screw 602 is threadedly connected to a ball nut pair 603. The top of the ball nut pair 603 is fixedly connected to an arc-shaped bottom plate 604. The tops of the left and right sides of the arc-shaped bottom plate 604 are fixedly connected to positioning frames 605. A rotating groove 606 is provided at the bottom of the arc-shaped bottom plate 604. A rotating wheel 607 is provided in the rotating groove 606. The ball nut pair 603 can move on the outside of the lead screw 602.

[0022] The output shaft of the driving motor 601 passes through the front of the workbench 2 and the front of the driving seat 5 and extends to the inner side of the driving seat 5 and is fixedly connected to the lead screw 602. The lead screw 602 is rotatably connected to the inner wall of the back side of the driving seat 5 away from the driving motor 601. A guide rod is arranged inside the driving seat 5, and the guide rod is located on the left and right sides of the lead screw 602. Guide rings are arranged on the left and right sides of the bottom of the arc-shaped bottom plate 604 corresponding to the guide rods. The arc-shaped bottom plate 604 is slidably connected to the guide rods through the guide rings, and can be moved and guided by the cooperation of the guide rings and the guide rods when the arc-shaped bottom plate 604 moves.

[0023] The sample is placed on the top of the curved bottom plate 604, and then rotated on the rotating wheel 607 at the bottom of the curved bottom plate 604, which can save effort when rotating the concrete sample and facilitate the adjustment of the position during cutting.

[0024] When it is necessary to cut the cylindrical sample, the driving motor 601 is controlled to work so that the driving motor 601 can drive the lead screw 602 to rotate. At this time, the ball nut pair 603 moves outside the lead screw 602. At the same time, the cutting disk 4 is controlled to move downward so that the blade on the cutting disk 4 can contact the concrete sample. At this time, the ball nut pair 603 moves backward outside the lead screw 602 so that the blade on the cutting disk 4 can cut the core of the sample.

[0025] For example 2, please refer to Figure 1-8 On the basis of the first embodiment, the present invention provides a technical solution: it also includes a clamping assembly 7, the clamping assembly 7 is composed of a driving frame 701, a driving motor 702, a second screw 703, a second ball nut pair 704, a moving frame 705, a connecting push plate 706, an extrusion frame 707 and a rubber clamping plate 708.

[0026] The driving frame 701 is fixedly connected to the outer side of the bottom of the arc bottom plate 604, the driving motor 702 is fixedly connected to the side of the driving frame 701 away from the arc bottom plate 604, the driving motor 702 has an output shaft, the screw 2 703 is fixedly connected to the output shaft of the driving motor 702, the ball nut pair 2 704 is threadedly connected to the outer side of the screw 2 703, the moving frame 705 is fixedly connected to the top of the ball nut pair 2 704, the connecting push plate 706 is rotatably connected to the middle part of the moving frame 705, the extrusion frame 707 is rotatably connected to the other side of the connecting push plate 706, and the rubber clamping plate 708 is fixedly connected to 7017 away from the side of the connecting push plate 706. The driving motor 702 can drive the screw 2 703 to rotate during operation.

[0027] It also includes an adsorption component 8, which is composed of a fixing plate 801, a spring 802, a negative pressure adsorption plate 803, a negative pressure adsorption hole 804 and an air release hole 805.

[0028] The fixed plate 801 is fixedly connected to the inner top of the rubber clamping plate 708, the spring 802 is fixedly connected to the left side of the fixed plate 801, the negative pressure adsorption plate 803 is fixedly connected to the end of the spring 802 away from the fixed plate 801, the negative pressure adsorption hole 804 is opened inside the negative pressure adsorption plate 803, the air release hole 805 is opened at the inner top of the rubber clamping plate 708, and the spring 802 can support the negative pressure adsorption plate 803.

[0029] The bottom of the rubber clamping plate 708 is rotatably connected to the middle of the positioning frame 605, and the output shaft of the driving motor 702 passes through the driving frame 701 and extends into the driving frame 701 to be fixedly connected to the second screw 703, and the second screw 703 is rotatably connected to the inner wall of the driving frame 701 away from the driving motor 702.

[0030] There are two drive frames 701, drive motor 702, lead screw 703, ball nut pair 704, movable frame 705, connecting push plate 706, extrusion frame 707 and rubber clamping plate 708. The two drive frames 701, drive motor 702, lead screw 703, ball nut pair 704, movable frame 705, connecting push plate 706, extrusion frame 707 and rubber clamping plate 708 are symmetrically distributed on the left and right sides of the arc bottom plate 604, and can drive the two rubber clamping plates 708 to rotate at the same time.

[0031] The negative pressure adsorption hole 804 and the air release hole 805 have the same inner diameter, so that the air in the negative pressure adsorption hole 804 can be ejected through the air release hole 805 .

[0032] When the sample needs to be fixed and clamped, the driving motor 702 is controlled to work so that the driving motor 702 drives the lead screw 703 to rotate when working. At this time, the ball nut pair 704 moves on the outside of the lead screw 703, so that the movable frame 705 on the top of the ball nut pair 704 moves, and the movable frame 705 pushes the connecting push plate 706, so that the extrusion frame 707 on the other side of the connecting push plate 706 is subjected to force, and the extrusion frame 707 pushes the rubber clamping plate 708 to fit the outer wall of the circular sample. At this time, the top side of the negative pressure adsorption plate 803 on the rubber clamping plate 708 first contacts the outer wall of the cylindrical sample. At this time, the air in the negative pressure adsorption hole 804 is squeezed out. At this time, the negative pressure adsorption plate 803 can be adsorbed on the outside of the cylindrical sample, and can perform adsorption and clamping work on the outside of the cylindrical sample during subsequent cutting, so as to avoid displacement of the sample after breaking during cutting.

[0033] When the cut sample needs to be removed, the driving motor 702 is controlled to work, so that the ball nut pair 704 moves outside the screw 703, and the extrusion frame 707 pulls the rubber clamping plate 708 to apply pressure. Since one side of the negative pressure adsorption plate 803 is adsorbed on the outer wall of the cylindrical sample, the rubber clamping plate 708 moves downward at this time, compressing the spring 802 on the negative pressure adsorption hole 804, and making the air release hole 805 on the rubber clamping plate 708 coincide with the negative pressure adsorption hole 804 on the negative pressure adsorption plate 803, so that the negative pressure in the negative pressure adsorption hole 804 can be released, so that the negative pressure adsorption plate 803 is separated from the outer wall of the sample, and the cut sample can be quickly removed.
