Therefore, the above terms should not be understood as limiting the present application.

[0054] The present application is further described in detail below in conjunction with the accompanying drawings. Figures 1 to 6 illustrate.

[0055] First aspect

[0056] The present application provides a cable anchor head, such as Figure 1 to Figure 2 As shown, it is provided with an operating mechanism 1, a telescopic arm 3 and a feeding mechanism 2. The telescopic direction of the telescopic arm 3 is parallel to the feeding direction. The operating mechanism 1 is arranged at the outlet end of the feeding mechanism 2. The telescopic arm 3 is connected to the operating mechanism 1 to drive the operating mechanism 1 to move along the feeding direction so as to precisely adjust the anchor machine head so that the operating port 11 on the operating mechanism 1 can be accurately aligned with the drill hole for grouting or anchor 4 installation.

[0057] Specifically, Figure 1 to Figure 2As shown, the feeding mechanism 2 includes a collecting pipe 21, and the operating mechanism 1 is provided with a discharge channel. The discharge channel and the axis of the collecting pipe 21 are in the same straight line, and the end of the discharge channel away from the collecting pipe 21 is the operating port 11; the feeding mechanism 2 is used to regularly guide the anchor cable 4 and the grouting pipe 5, so that the anchor cable 4 and the grouting pipe 5 can be guided into the collecting pipe 21, and then enter the operating mechanism 1, enter the borehole from the only operating port 11 to install the grouting pipe 5 or the anchor cable 4, so that the anchor cable head only needs to be aligned once when operating, that is, the operating port 11 is aligned with the borehole, and there is no need to position it again. The feeding mechanism 2 only needs to replace the grouting pipe 5 or the anchor cable 4 entering the collecting pipe 21 to realize grouting and anchor cable 4 installation, thereby saving a lot of secondary positioning time and improving operating efficiency.

[0058] Among them, Figure 1 to Figure 2 , Figure 3 As shown, the feeding mechanism 2 includes a mounting seat 26 and a first guide tube and a second guide tube. The first guide tube 22 and the second guide tube 23 are fixedly arranged on the mounting seat 26. The first guide tube 22 and the second guide tube 23 are basically arranged on the same plane. The first guide tube 22 and the second guide tube 23 are both tubular structures. The first guide tube 22 is used to accommodate the anchor cable 4, and the second guide tube 23 is used to guide the grouting tube 5. Figure 3 As shown, the outlet end of the first guide pipe 22 and the outlet end of the second guide pipe 23 are connected to the inlet end of the collecting pipe 21 at the same time, and there is a gap between the inlet ends of the first guide pipe 22 and the second guide pipe 23, so that the grouting pipe 5 and the anchor cable 4 have their own feeding routes. The grouting pipe 5 and the anchor cable 4 do not interfere with each other in the early stage and do not affect their respective feeding. They only need to choose one to enter the operating mechanism 1 when approaching the operating mechanism 1, which effectively saves positioning time and is conducive to improving work efficiency.

[0059] Further, such as Figure 2 , Figure 3 As shown, the axis of the second guide tube 23 and the collecting tube 21 are on the same straight line, wherein the axis of the first guide tube 22 and the axis of the second guide tube 23 have an angle θ, wherein 10°≤θ≤14°, i.e., the second guide tube 23 is inclined to the feeding direction, and the second guide tube 23 can guide the grouting tube 5 to move toward the collecting tube 21, so that the anchor cable 4 does not need to be deflected at an angle during feeding, and only needs the grouting tube 5 to be deflected at a smaller angle, thereby ensuring that the grouting tube 5 and the anchor cable 4 enter the collecting tube 21 smoothly.

[0060] Among them, the angle θ can be set to any one of 10°, 11°, 12°, 13°, and 14° to ensure that the grouting pipe 5 and the anchor cable 4 do not interfere with each other in the early stage of feeding. When the operation requires, the grouting pipe 5 only needs to be offset at a smaller angle, thereby reducing the difficulty of the grouting pipe 5 entering the collecting pipe 21 and ensuring smooth operation.

[0061] In particular, if Figure 1 , Figure 2 As shown, the mounting seat 26 is a box-type structure as a whole, and the side end of the mounting seat 26 is connected to the telescopic wall, that is, the telescopic arm 3 can simultaneously drive the feeding mechanism 2 and the operating mechanism 1 to move along the feeding direction; wherein, the first guide tube 22 has a relatively long overall length, and the side end of the first guide tube 22 is fixedly connected to the side end of the mounting seat 26 away from the telescopic wall, and the inlet end of the second guide tube 23 is connected to the end face of the mounting seat 26 close to the operating mechanism 1; wherein, the feeding mechanism 2 also includes a feeding assembly 25, which is arranged on the mounting seat 26, and the feeding assembly 25 forms a feeding channel in the mounting seat 26 for the grouting pipe 5 to pass through, and the outlet end of the feeding channel is connected to the inlet end of the first guide tube 22, and the feeding assembly 25 can drive the grouting pipe 5 to feed toward the first guide tube 22, so that the grouting pipe 5 can smoothly enter the first guide tube 22, so that the grouting pipe 5 has a large thrust to enter the collecting pipe 21 through the first guide tube 22.

[0062] In this embodiment, the feed assembly 25 includes a drive motor 251 and a drive wheel, and the drive wheel is arranged in the mounting seat 26 to form a feed channel; the drive motor 251 is connected to the drive wheel, and the drive motor 251 is used to provide driving force to the drive wheel so that the grouting pipe 5 can be displaced along the feed direction under the rotation of the drive wheel.

[0063] It should be noted that, in the present embodiment, the feeding assembly 25 for driving the grouting pipe 5 is arranged at the inlet end of the first guide pipe 22, and the first guide pipe 22 for guiding the grouting pipe 5 is arranged to be inclined, so that the feeding drive of the grouting pipe 5 and the inclined movement of the grouting pipe 5 are integrated together, so that the grouting pipe 5 has a larger and more sufficient power for deflection, so as to smoothly enter the collecting pipe 21, thereby improving the operating smoothness and efficiency of the anchor machine head.

[0064] Further, such as Figure 1 , Figure 2 , Figure 3 As shown, the feeding mechanism 2 also includes a third guide pipe 24, which is arranged at the end of the feeding assembly 25 away from the first guide pipe 22, that is, the outlet end of the third guide pipe 24 is connected to the inlet end of the feeding channel, wherein the axis of the third guide pipe 24 is parallel to the axis of the second guide pipe 23, and the axis of the third guide pipe 24 is in the same straight line as the feeding channel, so that the grouting pipe 5 entering the feeding channel can be guided in a straight line, ensuring that the feeding action of the feeding assembly 25 on the grouting pipe 5 is correct, so as to ensure that the grouting pipe 5 can smoothly enter the collecting pipe 21.

[0065] On the basis of any of the above embodiments, the operating mechanism 1 is further expanded; Figures 1 to 4As shown, a flushing joint 12 is provided at the inlet end of the discharge channel. The flushing joint 12 has a feed port coaxially arranged with the feed channel. The grouting pipe 5 enters into the discharge channel through the flushing joint 12. The flushing joint 12 is used to connect a water pipe joint to flush the outer wall of the grouting pipe 5, so that the grouting pipe 5 can ensure better cleanliness when being withdrawn.

[0066] Among them, there is a gap between the flushing joint 12 and the outlet end of the collecting pipe 21 to provide space for placing the water pipe joint. At the same time, when the liquid flushes the mud on the grouting pipe 5, the mud can fall from the gap between the flushing joint 12 and the collecting pipe 21, preventing the mud from entering the collecting pipe 21.

[0067] Specifically, Figure 4 As shown, the flushing joint 12 is a hollow structure, and the flushing joint 12 includes a water inlet 121, a water inlet channel and a water outlet 122. The hollow part of the flushing joint 12 is the water inlet channel, and the water inlet 121 is connected with the water outlet 122 through the water inlet channel, that is, the water inlet 121 is open on the outside of the flushing joint 12, and the water pipe can be connected to the water inlet 121 on the outer wall of the flushing joint 12, and the water outlet 122 is open on the inside of the flushing joint 12; wherein, there are at least two water outlets 122, and the water outlets 122 are equidistantly spaced along the circumferential direction of the inner side wall of the flushing joint 12; in use, the liquid enters the water inlet channel from the water inlet 121, and then flows out from the inner water outlet 122 of the flushing joint 12, surrounding the grouting pipe 5 for flushing, thereby increasing the probability of flushing away the mud and sand on the outside of the grouting pipe 5.

[0068] In this embodiment, the number of water outlets 122 is four.

[0069] On the basis of any of the above embodiments, the operating mechanism 1 is further expanded; Figure 4 , Figure 5 As shown, the operating mechanism 1 includes a bending assembly 13, which is used to bend the anchor cable 4 so that the anchor cable 4 can form a bending angle, increase the friction of the anchor cable 4 in the drill hole, and make the installation of the anchor cable 4 in the drill hole more stable.

[0070] Specifically, Figure 4 , Figure 5As shown, the operating mechanism 1 also includes a mounting support 134, which includes a top plate and a side plate, and a space for mounting the bending assembly 13 is formed in the mounting support 134; the flushing joint 12 is arranged on the side plate of the mounting support 134 close to the collecting pipe 21; the bending assembly 13 includes a bending drive member 131 and a bending member 132, the top of the bending drive member 131 is fixedly connected to the mounting support 134, the driving end of the bending drive member 131 is connected to the bending member 132, and the bending member 132 is provided with a bending opening 133 for the anchor cable 4 to pass through. Under normal conditions, the axis of the bending opening 133 is in the same straight line as the axis of the discharge channel, and the anchor cable 4 enters the bending opening 133 after passing through the flushing joint 12, and then passes through the operating opening 11;

[0071] Among them, an opening is provided at the bottom of the mounting support 134, and the bending drive member 131 can drive the bending member 132 to move toward the opening direction, so that the bottom of the bending member 132 exceeds the bottom of the mounting support 134. Since the anchor cable 4 passes through the bending opening 133, the anchor cable 4 can be driven to move during the movement of the bending member 132 to achieve the bending of the anchor cable 4.

[0072] In the embodiment, the feeding direction is parallel to the horizontal plane, and the driving direction of the bending driving member 131 on the bending member 132 is parallel to the vertical direction, that is, perpendicular to the feeding direction, so as to form a bending angle on the anchor cable 4.

[0073] In this embodiment, the bending driving component 131 is a cylinder-type driving component.

[0074] On the basis of any of the above embodiments, the operating mechanism 1 is further expanded; Figure 4 , Figure 5 As shown, the operating mechanism 1 further includes a shearing assembly 14 , which is located between the operating port 11 and the collecting pipe 21 , and is disposed at the side end of the bending assembly 13 away from the collecting pipe 21 , and is used to shear the anchor cable 4 .

[0075] Specifically, the shearing assembly 14 includes a hydraulic shear 142 and a bottom support 141. The hydraulic shear 142 is arranged at the upper end of the bottom support 141. The side end of the bottom support 141 is fixedly connected to the mounting support 134. The bottom support 141 has a channel for the anchor cable 4 or the grouting pipe 5 to pass through. The operating port 11 is the opening at the front end of the bottom support 141. At the same time, the bottom support 141 has a space for accommodating the hydraulic shear 142. The hydraulic shear 142 can cut the anchor cable 4 in the discharge channel.

[0076] Among them, the shearing component 14 is arranged at the front end of the bending component 13, so that after the anchor cable 4 is inserted into the hole of the previous anchor cable 4 and installed, the shearing component 14 cuts the anchor cable 4, and the remaining bent part of the anchor cable 4 can enter the next drill hole, thereby improving the installation stability of the anchor cable 4 and the drill hole.

[0077] It should be noted that, in the present application, the discharge channel is formed by the channel of the bottom support 141 , the mounting support 134 and the flushing joint 12 .

[0078] Second aspect

[0079] The present application provides an anchor trolley, comprising an anchor head in any embodiment provided in the first aspect, the anchor head having a feeding mechanism 2 for simultaneously arranging a grouting pipe 5 and an anchor cable 4, so that the grouting pipe 5 and the anchor cable 4 share an outlet, and only requires one positioning in actual use, which is convenient and quick, thereby improving the construction efficiency of the anchor trolley.

[0080] The anchor cable trolley of the present application is used as follows:

[0081] First, before feeding the grouting pipe 5, the anchor cable 4 is completely retracted into the first guide pipe 22, and the space of the collecting pipe 21 is completely left for the grouting pipe 5. The grouting operation is completed through the reel of the grouting pipe 5 and the feeding mechanism 2 of the grouting pipe 5. The bending assembly 13 and the shearing assembly 14 do not work, and the path is fully open, which does not affect the passage of the grouting pipe 5. After the grouting is completed, the water valve flushing switch on the vehicle is turned on, and water begins to flush the outer wall of the grouting pipe 5. The feeding assembly 25 reversely rotates the drive motor 251 to complete the retraction of the grouting pipe 5.

[0082] All grouting pipes 5 are retracted into the second guide pipe 23, and the space of the collection pipe 21 is fully reserved for the anchor cable 4. When the anchor cable 4 is in operation, the entire anchor cable 4 feeding operation is completed through the anchor cable 4 reel and the anchor cable 4 feeding mechanism 2 on the vehicle. When the anchor cable 4 is inserted, the bending assembly 13 is driven from time to time to bend and deform the anchor cable 4. When the anchor cable 4 is inserted to the bottom of the hole, the shearing assembly 14 is driven to complete the cutting of the anchor cable 4.

[0083] Repeat the above operation to carry out the anchor cable 4 construction operation of the next borehole.

[0084] The third aspect

[0085] The present application provides a method for constructing an anchor cable trolley. Figure 6 As shown, it includes the following steps:

[0086] Step 1: Determine that there is no anchor cable 4 in the collecting pipe 21, and control the grouting pipe 5 to enter the operating mechanism 1 through the collecting pipe 21;

[0087] Step 2: After the grouting is completed, the grouting pipe 5 is controlled to exit the collecting pipe 21;

[0088] Step 3: Determine that there is no grouting pipe 5 in the collecting pipe 21, and control the anchor cable 4 to enter the operating mechanism 1 through the collecting pipe 21;

[0089] Step 4: After the anchor cable 4 is installed, the operating mechanism 1 is controlled to shear the anchor cable 4 .

[0090] In this embodiment, it is necessary to ensure that when the anchor trolley is working, either the grouting pipe 5 or the anchor cable 4 exists in the collecting pipe 21, or both do not exist, so as to ensure that the grouting pipe 5 and the anchor cable 4 will not interfere with each other in the collecting pipe 21, and then ensure that the only working port 11 of the operating mechanism 1 can only be used for either the grouting pipe 5 or the anchor cable 4 to operate, so as to ensure the smooth operation of the anchor trolley; at the same time, by controlling the grouting pipe 5 and the anchor cable 4 to enter the working port 11 through the collecting pipe 21 at an offset to operate the drilling hole, the anchor trolley of the present application only needs to be aligned once after adopting this construction method, that is, the working port 11 is aligned with the drilling hole, and there is no need to position it again. The feeding mechanism 2 only needs to replace the grouting pipe 5 or the anchor cable 4 entering the collecting pipe 21 to realize grouting and installation of the anchor cable 4, thereby saving a lot of secondary positioning time and improving operating efficiency.

[0091] Furthermore, in step 2, after the grouting is completed, the grouting pipe 5 is controlled to withdraw from between the collecting pipes 21 , and the flushing joint 12 is controlled to connect to the water source to flush the outer wall of the grouting pipe 5 .

[0092] In this embodiment, after grouting is completed, the water valve flushing switch on the vehicle is turned on, and water begins to flush the outer wall of the grouting pipe 5. The feed assembly 25 reversely rotates the drive motor 251 to complete the retraction of the grouting pipe 5, so that the retracted grouting pipe 5 is clean and tidy.

[0093] Further, after step three and before step four, during the installation of the anchor cable 4, the bending assembly 13 is controlled to bend the anchor cable 4.

[0094] In this embodiment, during the installation of the anchor cable 4, the bending assembly 13 is driven from time to time to bend and deform the anchor cable 4 so that the anchor cable 4 can form a bending angle, increase the friction of the anchor cable 4 in the drill hole, and make the installation of the anchor cable 4 in the drill hole more stable.

[0095] It should be noted that the various embodiments of the present application can be arbitrarily combined into a new embodiment if the solutions do not conflict and the technical solutions can coexist.

[0096] The present application is described in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
