Description

Technical Field

[0001] The present application relates to the technical field of TBM tool replacement, and in particular to a tool transportation device for TBM face tool replacement. Background Art

[0002] TBM equipment is a tunnel boring machine, which is used in hard rock conditions. Therefore, the cutting tools of TBM equipment wear quickly and need to be regularly maintained and inspected.

[0003] When the TBM is shut down for maintenance, the tools installed on the cutter disc are mainly inspected and severely worn tools are replaced. The tools can only be transported to the rear of the TBM main machine through the crane in the rear supporting equipment. After the tools are transported to the rear of the main machine, they are sent to the cutter disc manually.

[0004] For small-diameter TBM equipment, the space inside the main machine is very limited, and people need to bend their bodies to walk inside it. Therefore, it is difficult to directly carry tools weighing hundreds of pounds inside the small-diameter TBM equipment.

[0005] Currently, most existing transport devices transport tools via slide rails and hoists. The slide rails are mostly linear and cannot be adjusted according to actual working conditions, resulting in a defect of low applicability of the transport device. Utility Model Content

[0011] Pneumatic hoist, pneumatic hoist is used to pull the tool.

[0012] By adopting the above technical solution, the slide rail is of two sections. The adjusting screw is moved by rotating the adjusting screw sleeve. There is self-locking between the adjusting screw sleeve and the adjusting screw, thereby being able to support the tilting section of the column. The tilting angle of the tilting section is adjusted through the above structure, thereby adapting to a variety of working conditions and improving the applicability of the transportation device.

During the rotation of the inclined section, the ball rolls in the rolling groove, and the friction force of rolling friction is less than the friction force of sliding friction, thereby improving the movement comfort of the adjusting screw and the inclined section. One end of the inclined section is fixed by the ear plate, thereby improving the stability of the device, thereby improving the stability of tool transportation.

The linkage part is used to extrude the clamping plate. The driving screw is threadedly connected to the inclined section. One end of the driving screw extends to the outside, and the other end of the driving screw extends into the trigger cavity to extrude the linkage part.

[0020] By adopting the above technical solution, when the driving screw extends into the trigger chamber, the driving screw squeezes the linkage part, thereby the linkage part squeezes the clamping plate, and the clamping plate clamps the ball bearing; when the driving screw moves away from the linkage part, the reset spring releases the elastic force to overcome the force exerted on the linkage part and the clamping plate, thereby resetting the linkage part and the clamping plate.

[0021] Optionally, an auxiliary spring is provided in the trigger chamber, and two ends of the auxiliary spring are respectively fixedly connected to the linkage part and the inclined section.

[0026] By adopting the above technical solution, the staff rotates the adjusting screw to make the upper spacing screw sleeve and the lower spacing screw sleeve move away from each other or move towards each other, thereby adjusting the distance between the upper pad and the lower pad, thereby adjusting the height of the horizontal section according to the working conditions or actual needs, thereby further improving the applicability of the device.

[0027] Optionally, a blocking rod is fixedly connected to one end of the horizontal section away from the inclined section.

[0028] By adopting the above technical solution, the blocking rod can prevent the tool from detaching from the horizontal section, thereby improving the safety of tool transportation.

A cushion block 6 is fixedly provided below the horizontal section 11.

[0042] Adjust the height of the cushion block 6 and the tilt angle of the inclined section 12 according to the working conditions and actual needs. After the height of the cushion block 6 and the tilt angle of the inclined section 12 are adjusted, pass the fixing pin through the positioning hole 41 and the mounting hole reserved in the equipment to fix the inclined section 12, and then fix the horizontal section 11 through the cushion block 6.

[0049] After adjusting the inclination angle of the inclination section 12 to the required one, the staff rotates the driving screw 52, ​​and the driving screw 52 extends into the trigger chamber 125. During the extension process, the driving screw 52 squeezes the inclined surface at the top of the linkage part 51, so that the linkage part 51 squeezes the clamping plate 122 through the inclined surface at its bottom. The clamping plate 122 is squeezed and slides in the slide groove 123 until the bottom of the linkage part 51 extends out of the avoidance groove 128. At this time, the two clamping plates 122 clamp and fix the ball 222.

[0050] When the splint 122 is squeezed, the splint 122 stretches the return spring 124, and the return spring 124 accumulates elastic potential energy; when the linkage part 51 is squeezed, the linkage part 51 slides along the guide rod 126, and the linkage part 51 compresses the auxiliary spring 127, and the auxiliary spring 127 accumulates elastic potential energy.

[0051] refer to Figure 1 and Figure 6 There are two pads 6, which are respectively arranged on both sides of the horizontal section 11. The pads 6 include an upper pad 61, a lower pad 62 and a distance adjustment component 63. The upper pad 61 is fixed to the horizontal section 11, the lower pad 62 is arranged opposite to the upper pad 61, and the distance adjustment component 63 is arranged between the upper pad 61 and the lower pad 62.

[0052] refer to Figure 6The pitch adjusting assembly 63 includes a pitch adjusting screw 633, which is a bidirectional screw. Both ends of the pitch adjusting screw 633 are provided with threads, and the threads at both ends of the pitch adjusting screw 633 have opposite rotation directions.

[0054] The staff rotates the rotating rod 6331, and the rotating rod 6331 drives the pitch-adjusting screw 633 to rotate, and the pitch-adjusting screw 633 drives the upper pitch-adjusting screw sleeve 631 and the lower pitch-adjusting screw sleeve 632 to move away from or towards each other. When the upper pitch-adjusting screw sleeve 631 and the lower pitch-adjusting screw sleeve 632 are close to each other, the upper pad 61 and the lower pad 62 are close to each other, thereby reducing the height of the cushion block 6; when the upper pitch-adjusting screw sleeve 631 and the lower pitch-adjusting screw sleeve 632 are far away from each other, the upper pad 61 and the lower pad 62 are far away from each other, thereby increasing the height of the cushion block 6.

[0055] The implementation principle of a tool transportation device for tool change at the TBM face in the embodiment of the present application is as follows: the staff rotates the adjusting screw sleeve 221 to drive the adjusting screw 22 to move upward or downward, thereby adjusting the inclination angle of the inclined section 12; after the inclination angle of the inclined section 12 is adjusted, the staff rotates the driving screw 52, ​​thereby allowing the two clamping plates 122 to clamp and fix the ball 222. Then the staff passes the fixing pin through the positioning hole 41 and the mounting hole reserved in the equipment, thereby fixing one end of the inclined section 12; after fixing one end of the inclined section 12, the staff rotates the rotating rod 6331 to adjust the height of the cushion block 6 to the required height, and then fixes the lower pad 62 to the equipment through bolts. Finally, the tool is placed on the horizontal section 11, and the tool is pulled by the pneumatic hoist 3, and the tool slides along the horizontal section 11 and the inclined section 12 until the tool is transported to the specified position. Through the above structure, the effect of improving the applicability of the transportation device is achieved.
