[0002] In the field of underground engineering, the application of shield construction is becoming more and more extensive. At present, many large-scale infrastructure projects such as water diversion projects, highway and railway tunnels have been rapidly planned and constructed in various regions at home and abroad, and the demand for large-diameter slurry shields is increasing. The installation method of the traditional shield cutter disc hob generally includes the hob cutter body, cutter box, fasteners, bolts, nuts, etc., with a relatively large number of parts, and the disassembly and assembly actions are relatively complicated. At present, the tool detection and tool changing work in the construction process of the full-section tunnel boring machine mainly relies on manual operation. Manual tool changing operations under construction environments such as deep burial and high water pressure have great safety risks, and are prone to major safety accidents such as casualties. In addition, the tool changing efficiency is low. It is imperative to realize tool detection and tool changing operations in an efficient and safe "machine-for-man" operation mode. Therefore, in order to facilitate the robot tool changing operation, we need to develop a tool holder installation method that is easy to operate and suitable for robot arm operation.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figure 1 and 2 As shown, a novel integrated tool installation structure includes a tool box 9, a mounting portion 10 is provided in the tool box 9, a gap is formed between the mounting portions 10, and the upper and lower portions of the mounting portions 10 are provided with oblique end surfaces. A tool integration system is provided in the tool box 9, and the tool integration system includes a tool assembly, a mounting assembly, and a clamping assembly. Before installation, the three assemblies need to be combined and connected into an integrated tool integration system, and the entire tool integration system needs to be inserted into the tool box for installation.

[0029] The tool assembly includes a hob 1 in the middle and end blocks 2 at both ends. The hob 1 is rotatably arranged between the end blocks 2. The end blocks 2 are connected to studs 3. The hob 1, end blocks 2 and studs 3 form an integrated structure. A trapezoidal groove is provided at the bottom of the end block 2.

[0030] An installation component is sleeved on the stud 3, and the installation component includes a tensioning block I4 and a sleeve 5 both of which are sleeved on the stud 3. The upper part of the tensioning block I4 is provided with a trapezoidal protrusion that cooperates with the trapezoidal groove, and the two ends of the lower part of the tensioning block I4 are provided with inclined end surfaces that cooperate with the upper part of the installation part. The tensioning block I4 is connected to one end of the sleeve 5, and the other end of the sleeve 5 passing through the gap is provided with a clamping part I.

[0031] The installation assembly also includes a tensioning block II6, and the clamping assembly includes a nut 8. The stud 3 passes through the gap and is threadedly connected to the nut 8. The tensioning block II6 is sleeved on the stud 3. The two ends of the upper part of the tensioning block II6 are provided with inclined end surfaces that cooperate with the lower part of the installation part. The lower part of the tensioning block II6 is provided with a hexagonal clamping part II, and the clamping part II cooperates with the nut 8. A clamping groove 7 is provided in the tensioning block II6, and the clamping part I is sleeved in the clamping groove 7. The cross-sections of the clamping part I and the clamping groove 7 are both hexagonal shapes that are clamped and matched with each other.

[0032] like Figure 3 and 4 As shown, the installation structure of the present invention is back-mounted. During the tool installation process, the A surface of the tension block I and the B surface of the tool box are perpendicular. After the installation is completed, the A surface and the B surface are parallel.

[0033] like Figures 5 to 8 As shown, the specific installation steps of the present invention are as follows: Step I, the tool integration system is gradually installed from the back of the tool box according to the existing state, at this time, the A surface of the tension block I is perpendicular to the B surface of the tool box, and the tension block I passes through the gap and is installed within the predetermined range; Step II, at this time, the tension block II is rotated 90 degrees by using the clamping part II, and the tension block I is affected by the clamping part I and the clamping groove, and rotates together with the tension block II; Step III, rotate until the A surface of the tension block I is parallel to the B surface of the tool box; Step IV, tighten the screw by rotating the nut, so that the end block is wedged with the tension block I, the tension block I and the mounting part are wedged, and the tension block II and the mounting part are wedged, completing the entire assembly process. The tool removal process can be reversed.

[0034] Example 2

[0035] On the basis of Example 1, the tension block II is cancelled, and a nut larger than the gap is adopted. The tension block I is turned directly through the clamping part I, and the nut is pressed on the mounting part to realize the pulling installation of the tool.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
