Description

Technical Field

[0001] The invention relates to the field of cutting equipment, and in particular to a rock core sample processing device for engineering detection. Background Art

[0002] The double-blade rock core cutting machine is a device used to cut highway and geological stone specimens. The stone cutting surface is flat and smooth when used. It can also be used to cut concrete, coring machine core samples, natural stone, marble and other samples. It is widely used in the sample preparation field of scientific research departments such as petroleum, geology, coal, highways, bridges, etc.

[0003] The functions of the double-blade cutting machines on the market are similar, but there are still defects in some specific details of operation. The existing double-blade cutting machines are not convenient for adjusting the spacing between the cutting blades. When processing core samples of different heights, the saw blades need to be manually disassembled to add or remove gaskets. The operation is cumbersome, time-consuming and labor-intensive. There are also occasional parts of the sample such as steel bars or wire pipes that need to be cut off, and the position of the saw blade needs to be manually compared to avoid them. The accuracy cannot be guaranteed and it takes a long time.

[0004] To this end, we use this technical solution to solve the problem of complicated operation of the existing double-blade cutting machine. Summary of the invention

[0005] The purpose of the present invention is to improve the double-blade cutting machine in the prior art. Compared with the prior art, a rock core sample processing device for engineering detection is provided. By improving the existing double-blade cutting machine, a hydraulic clamp is used to automatically clamp the sample, which effectively prevents the rock core sample from shaking during the cutting process and affecting the cutting accuracy. The blade spacing is adjusted by setting an adjustable double-blade group. Not only is the operation convenient, but the clamping effect of the positioning pin during adjustment is also used to trigger the position identifier, so that the position identifier and the linkage projector are linked. In this way, the movement trajectory of the blade can be projected on the hydraulic clamp, which helps the rock core sample avoid the position of steel bars and wire pipes when clamping, effectively improving the operating efficiency.

[0006] It can quickly adjust the distance of the cutting blade and automatically mark the blade's trajectory to help avoid steel bars and wire tubes in the core sample.

[0007] Furthermore, the adjustable double-knife group includes a fixed shaft connected to the output end of the driving motor, and a blade is installed on the fixed shaft, a moving shaft is sleeved on the fixed shaft, and a blade is also installed on the moving shaft, the outer wall of the fixed shaft is fixedly connected with a plurality of splines distributed around at equal intervals, and the inner wall of the moving shaft is provided with a plurality of key grooves matching the splines, the inner wall of the fixed shaft is provided with an adjusting cavity, and the inner walls on the upper and lower sides of the adjusting cavity are provided with a plurality of positioning grooves distributed at equal intervals, the inner wall of the moving shaft is fixedly connected with an adjusting column, and the adjusting column is slidably connected to the adjusting cavity, and a cavity is provided at one end of the adjusting column located in the adjusting cavity, an adjusting screw is threadedly connected to the inner wall of the adjusting column, and two ends of the adjusting screw respectively penetrate the outside of the moving shaft and the cavity, and one end of the adjusting screw located in the cavity is fixedly connected A positioning cone is connected, and positioning pins that are engaged with the positioning groove are slidably connected on the upper and lower sides of the cavity, and the positioning pins are against the positioning cone. A damping bearing is installed on the inner wall of the cavity, and the adjusting screw passes through the damping bearing and is threadedly connected with it. This structure is for the convenience of adjusting the spacing between the two blades. When adjusting, first push and pull the movable shaft to move the blade on the movable shaft to the required position, and then rotate the adjusting screw to advance the rotation. While the adjusting screw moves forward, the positioning cone is used to push the positioning pin outward, so that the positioning pin is stuck in the positioning groove, thereby fixing the position of the movable shaft, so as to achieve the purpose of quickly adjusting the blade spacing. The damping effect of the damping bearing allows the adjusting screw to turn and stop immediately, which will not cause the adjusting screw to rotate at will and affect the engagement of the positioning pin.

[0008] Furthermore, the positioning cone and the positioning pin are connected by magnetic attraction, and both the positioning cone and the positioning pin are made of smooth and wear-resistant materials. The positioning cone uses the inclined surface to push the positioning pin outward, and uses magnetic attraction to automatically disengage the positioning pin from the positioning groove.

[0009] Furthermore, a position identifier is fixedly embedded on the inner wall of the fixed shaft near the positioning groove. The position identifier includes a circuit board, and a flexible film is installed on the circuit board at the position opposite to each positioning groove. When the positioning pin is inserted into the positioning groove, the positioning pin also touches and presses the flexible film, thereby allowing the flexible film to trigger the switch on the circuit board, thereby identifying the moving position of the blade on the moving shaft.

[0010] Optionally, a linkage light projector is also installed on the side wall of the protective cover close to the hydraulic clamp, and the linkage light projector includes a light-transmitting shell, a fixed light projector corresponding to the blade on the fixed shaft is installed at one end of the light-transmitting shell, a sliding cavity is opened on the inner wall of the light-transmitting shell on one side of the fixed light projector, and a dynamic light projector corresponding to the blade on the dynamic shaft is slidably connected in the sliding cavity, a screw motor is installed at one end of the sliding cavity, and the position identifier is electrically connected to the screw motor through the control processor, and the output end of the screw motor is connected to a secondary lead screw, and the secondary lead screw passes through the dynamic light projector and is threadedly connected to it.

[0011] Optionally, the fixed light projector and the dynamic light projector have the same structure, the fixed light projector includes a waterproof shell, and a plurality of laser emitters are installed inside the waterproof shell, a light guide plate is fixedly embedded on the inner wall of the waterproof shell facing the laser emitter, and a plurality of light guide rods distributed in a scattered manner are fixedly connected to the side wall of the light guide plate away from the laser emitter, the light emitted by the laser emitter is guided by the light guide plate and the light guide rod, and a light curtain is projected on the hydraulic clamp, and the straight line where the light curtain is located is the trajectory line of the blade, thereby helping the core sample to avoid steel bars and wire tubes.

[0012] Furthermore, the clamping pad includes an upper steel plate layer and a lower polyurethane layer, and a rubber layer is fixedly connected between the steel plate layer and the polyurethane layer. Since the clamping pad is in direct contact with the core sample when hydraulic clamping is adopted, if the hydraulic pressure is not well controlled, it is very easy to cause the core sample to break and break. Therefore, a rubber layer is added to provide buffering without affecting the clamping of the core sample.

[0013] Furthermore, the filter box includes a square cylinder, and a filter net is fixedly connected to the inner wall of the square cylinder. The waste water and waste heads generated by cutting fall into the square cylinder. After being filtered by the filter net, the waste heads and large particles of waste are retained, which facilitates the treatment of the waste water.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) This scheme improves the existing double-blade cutting machine and uses a hydraulic clamp to automatically clamp the sample, effectively preventing the rock core sample from shaking during the cutting process and affecting the cutting accuracy. By setting an adjustable double-blade group to adjust the blade spacing, it is not only convenient to operate, but also uses the clamping effect of the positioning pin during adjustment to trigger the position identifier, so that the position identifier and the linkage projector can be linked. In this way, the movement trajectory of the blade can be projected on the hydraulic clamp, helping the rock core sample to avoid the position of steel bars and wire pipes when clamping, effectively improving the operating efficiency, realizing rapid adjustment of the cutting blade, and automatically marking the blade trajectory to help avoid steel bars and wire pipes in the core sample.

A damping bearing is installed on the inner wall of the cavity, and the adjusting screw passes through the damping bearing and is connected with it. This structure is for the convenience of adjusting the spacing between the two blades. When adjusting, first push and pull the movable shaft to move the blade on the movable shaft to the required position, and then rotate the adjusting screw to advance the rotation.

The damping effect of the damping bearing allows the adjusting screw to turn and stop immediately, which will not cause the adjusting screw to rotate at will and affect the engagement of the positioning pin.

[0017] (3) The positioning cone and the positioning pin are connected by magnetic attraction, and both the positioning cone and the positioning pin are made of smooth and wear-resistant materials. The positioning cone uses the inclined surface to push the positioning pin outward, and uses the magnetic attraction to automatically disengage the positioning pin from the positioning groove.

[0018] (4) A position identifier is fixedly embedded on the inner wall of the fixed shaft near the positioning groove. The position identifier includes a circuit board, and a flexible film is installed on the circuit board at the position opposite to each positioning groove. When the positioning pin is inserted into the positioning groove, the positioning pin also presses the flexible film, thereby allowing the flexible film to trigger the switch on the circuit board, thereby identifying the moving position of the blade on the moving shaft.

Since the clamping pad 805 is in direct contact with the core sample when hydraulic clamping is adopted, if the hydraulic pressure is not well controlled, it is very easy to cause the core sample to break and break, so a rubber layer 8053 is added to provide a buffer, and it does not affect the clamping of the core sample.

[0041] Based on Example 1, please refer to Figure 5 , 7 , a position identifier 1104 is fixedly embedded on the inner wall of the fixed shaft 11 near the positioning groove 1103, and the position identifier 1104 includes a circuit board 11041, and a flexible film 11042 is installed on the circuit board 11041 at the position facing each positioning groove 1103 (the specific structure and working principle refer to the flexible film keyboard in the prior art, which will not be described in detail here). When the positioning pin 16 is inserted into the positioning groove 1103, the positioning pin 16 also touches the flexible film 11042, and then the flexible film 11042 triggers the switch on the circuit board 11041, so as to identify the moving position of the blade on the driving shaft 12;

[0042] See also Fig. 9A linkage light projector 5 is also installed on the side wall of the protective cover 4 near the hydraulic clamp 8. The linkage light projector 5 includes a light-transmitting shell 501. A fixed light projector 502 corresponding to the blade on the fixed shaft 11 is installed at one end of the light-transmitting shell 501. A sliding cavity is opened on the inner wall of the light-transmitting shell 501 on one side of the fixed light projector 502, and a dynamic light projector 503 corresponding to the blade on the dynamic shaft 12 is slidably connected in the sliding cavity.

After the light emitted by the laser emitter 19 passes through the light guide plate 20 and the light guide rods 21, a light curtain is projected on the hydraulic clamp 8, and the straight line where the light curtain is located is the trajectory line of the blade, thereby helping the core sample to avoid steel bars and wire tubes;

When the positioning pin 16 triggers the circuit board 11041, the circuit board 11041 automatically identifies the moving position of the blade, and then starts the lead screw motor 504 through the control processor to drive the dynamic light projector 503 to move to a position facing the blade, so that the dynamic light projector 503 can project the trajectory light of the blade on the hydraulic clamp 8, which can help avoid steel bars and wire pipes when clamping the core sample.

[0044] The working principle of this scheme is as follows: first, the distance between the blades is adjusted according to the length of the core sample to be cut. When adjusting, the movable shaft 12 is pulled back and forth to make the distance between the two blades at the position that needs to be adjusted. Then, the adjusting screw 14 is rotated to drive the positioning cone 15 forward. The positioning cone 15 pushes the positioning pin 16 outward on the inclined surface, so that the positioning pin 16 is engaged with the positioning groove 1103. Due to the damping and limiting effect of the damping bearing 17, the adjusting screw 14 will not rotate at will after it is loosened, so that the positioning of the movable shaft 12 is achieved. When the positioning pin 16 is inserted into the positioning groove 1103, it also presses the flexible film 11042. Then, the flexible film 11042 triggers the switch on the circuit board 11041 to identify the moving position of the blade on the moving shaft 12. Then, the circuit board 11041 starts the screw motor 504 through the control processor to move the dynamic light projector 503 to the same straight line as the blade. In this way, the fixed light projector 502 and the dynamic light projector 503 can project the trajectory of the blade on the hydraulic clamp 8, and then avoid steel bars and wire pipes when clamping the core sample. When clamping the core sample, place it on the bottom slide 801, and use the hydraulic action to press the clamping pad 805 on the core sample, thereby realizing automatic clamping of the core sample.
