Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a convenient installation device for a crawler vehicle type advanced geological detector. Background Art

[0002] During the construction of the tunnel, the geological conditions are relatively complex. During the excavation process, extreme working conditions such as rock bursts and sudden water inrush may be encountered. The adverse geological phenomena such as structural planes, weak interlayers, and faults naturally existing in the surrounding rock pose a challenge to the stability of the construction. If not properly handled, serious accidents such as large deformation, damage to the support structure, and even landslides may occur. At present, people mainly use the method of advanced geological prediction to obtain the surrounding rock information in front of the construction face to determine the location of the adverse geological body so as to respond in advance.

[0003] In order to ensure the safety of construction, it is very important to confirm the surrounding rock conditions in front of the face. Tunnel construction parties usually use the TSP advanced geological prediction method to timely grasp the surrounding rock conditions in front of the face, and make design changes according to actual conditions to ensure smooth construction. However, when actually conducting advanced geological prediction, the anchor rods used in the support and reinforcement process are often used to install TSP detectors. Data cannot be collected at the best detection position for advanced geological prediction, which can easily cause errors in the prediction and seriously affect the construction progress.

[0006] The detector installation mechanism includes an installation bin connected to the lower end of the anchor drill and a storage bin connected to the bottom end of the installation bin, the installation bin is arranged horizontally, the storage bin is arranged vertically, and the two are arranged in a T shape, an installation outlet is opened at one end of the installation bin, and a pushing mechanism for pushing materials toward the installation outlet is arranged in the installation bin;

[0007] A compression spring is connected to the bottom of the storage bin, a support plate is connected to the top of the compression spring, both sides of the support plate are slidably connected to the storage bin respectively, a discharge port is provided at the upper end of the rear side of the storage bin, and a moving mechanism for moving the support plate up and down is provided on one side of the storage bin;

[0008] Two slide grooves are respectively arranged at the two ends of the supporting plate, and slide bars corresponding to the slide grooves are respectively arranged on the inner walls on both sides of the storage bin, and the slide bars are slidably mounted in the slide grooves.

[0009] Preferably, the pushing mechanism includes a first push plate and a second push plate slidably arranged in the installation bin, two first-level hydraulic cylinders are arranged between the first-level push plate and the rear baffle of the installation bin, a second-level hydraulic cylinder is arranged on the first-level push plate between the two first-level hydraulic cylinders, and the telescopic end of the second-level hydraulic cylinder passes through the first-level push plate and is connected to the second-level push plate.

[0010] Preferably, the moving mechanism includes two through slots opened on one side of the storage bin, a plurality of locking slots opened on both sides along the length of the through slots, two connecting rods connected to one end of the supporting plate, and a swing handle rotatably connected to the connecting rods, the through slots are connected to the storage bin, the locking slots and the through slots form a cross structure, one end of the connecting rod extends into the through slot and is hinged to the swing handle, so that the swing handle can swing forward and backward along the connecting rod and can be stuck in the locking slot, and the two connecting rods are located between the two sliding slots.

[0011] Preferably, the length of the swing handle is smaller than the length of the through slot.

[0012] Preferably, the supporting plate is arranged to be tilted downward toward one side of the rear baffle.

[0013] Preferably, the mechanical arm structure comprises a rotating base, a third mechanical arm, a second mechanical arm, a first mechanical arm, and a rotating support which are hinged in sequence, and the anchor drilling rig is arranged on the rotating support.

[0014] The beneficial effects of the utility model are:

[0015] 1. The utility model can make the crawler vehicle adapt to more complex driving environment by using a crawler driving device, and the multi-degree-of-freedom mechanical arm structure can ensure that the anchor rod and the detector can be installed at any required position of the tunnel; the anchor drilling rig can install the anchor rod on the rock wall of the tunnel, reinforce the surrounding rock, and ensure the safety of construction; the detector installation mechanism includes a detector storage bin and a detector installation bin, and multiple detectors can be placed in the detector storage bin at one time, and multiple installations can be performed to improve work efficiency, so that the detector body can be installed in the best detection position, thereby making the data of geological detection and prediction more accurate.

[0016] 2. When the utility model installs the detector body into the storage bin, the swing handle is pulled downward in the through groove, so that the connecting rod and the supporting plate move toward the bottom of the storage bin together. The compression spring is continuously compressed as the supporting plate moves downward, so that the upper end of the storage bin leaves installation space for accommodating the detector body. Then, the detector bodies are placed into the storage bin one by one through the discharge port, and the loading of the detector bodies is completed. Finally, the swing handle is snapped into the corresponding locking groove. The overall structure is simple and easy to operate.

[0017] 3. The inclined arrangement of the supporting plate in the utility model can make the detector body tilted in the storage bin along with the inclination angle of the supporting plate. When the detector body enters the installation bin, the pushing mechanism composed of the first-level hydraulic cylinder and the first-level push plate and the second-level hydraulic cylinder and the second-level push plate arranged in the installation bin is utilized. The first-level push plate and the second-level push plate are driven by the hydraulic cylinder to telescope and move, providing a channel for the detector to move into the installation bin. When the second-level push plate pushes the detector out of the installation outlet, the first-level push plate moves from the lowest end to the highest end of the detector body, and slowly presses the detector body back into the storage bin. At this time, the first-level push plate stays at the highest point of the detector body to prevent the detector body located in the storage bin from popping out. The movement of the first-level push plate and the second-level push plate and the ingenious cooperation of the supporting plate and the compression spring enable the detector body to be pushed out of the installation outlet in turn and installed quickly, thereby improving the installation efficiency of the detector body.

[0034] The detector installation mechanism 1 includes an installation bin 12 connected to the lower end of the anchor drill 2 and a storage bin 17 connected to the bottom end of the installation bin 12. The storage bin 17 is used to store multiple detector bodies 19. The installation bin 12 is arranged horizontally, and the storage bin 17 is arranged vertically. The two are arranged in a T-shape. An installation outlet 11 is opened at one end of the installation bin 12. A pushing mechanism for pushing materials toward the installation outlet 11 is arranged in the installation bin 12. The pushing mechanism includes a primary push plate 15 and a secondary push plate 13 slidingly arranged in the installation bin 12. Two primary hydraulic cylinders 22 are arranged between the primary push plate 15 and the rear baffle 16 of the installation bin 12. A secondary hydraulic cylinder 14 is arranged on the primary push plate 15 between the two primary hydraulic cylinders 22. The telescopic end of the secondary hydraulic cylinder 14 passes through the primary push plate 15 and is connected to the secondary push plate 13. The detector body 19 can be pushed out from the installation outlet 11 for installation through the cooperation of the primary push plate 15 and the secondary push plate 13.

[0035] A compression spring 21 is connected to the bottom of the storage bin 17, and a support plate 20 is connected to the top of the compression spring 21. Both sides of the support plate 20 are slidably connected to the storage bin 17 respectively, and the support plate 20 is tilted downward toward one side of the rear baffle 16. The tilted support plate 20 can make the detector body 19 tilted in the storage bin 17. When the first-level push plate 15 is extended toward the installation outlet 11, the detector body 19 is pushed and pressed down from the lower side. At this time, the detector body 19 at the uppermost end of the storage bin 17 is pressed back into the storage bin 17.

[0036] A discharge port 18 is provided at the upper end of the rear side of the storage bin 17, and a moving mechanism for moving the support plate 20 up and down is provided on one side of the storage bin 17; two slide grooves 6 are provided at both ends of the support plate 20, and slide bars corresponding to the slide grooves 6 are provided on the inner walls of both sides of the storage bin 17, and the slide bars are slidably mounted in the slide grooves 6 to ensure the smooth sliding of the spring plate. The support plate 20 is used to support the detector body 19. The moving mechanism includes two through slots 51 opened on one side of the storage bin 17, a plurality of locking slots 50 opened on both sides of the through slots 51 along the length thereof, two connecting rods 52 connected to one end of the supporting plate 20, and a swinging handle 53 rotatably connected to the connecting rod 52. The through slots 51 are connected to the storage bin 17, the locking slots 50 and the through slots 51 form a cross-shaped structure, one end of the connecting rod 52 extends into the through slot 51 and is hinged to the swinging handle 53, so that the swinging handle 53 can swing forward and backward along the connecting rod 52 and can be snapped into the locking slot 50. The length of the swinging handle 53 is less than the length of the through slot 51 so that the swinging handle 53 can be snapped into the through slot 51, and the two connecting rods 52 are both located between the two slide slots 6. By pulling the swing handle 53 into the through slot 51 and making it move up and down along the through slot 51, the detector body on the support plate moves upward in the storage bin 17 under the action of the compression spring, and by controlling the positions of the primary push plate and the secondary push plate in the pushing mechanism, the two are driven by the primary hydraulic cylinder and the secondary hydraulic cylinder to be located at the same position as shown in FIG. Figure 6 Point A in the figure, that is, the installation bin 12 is connected with the storage bin 17 and the installation outlet 11, and enters the installation bin 12.

[0037] When the utility model is operated, the fixed anchor rod is installed first: the crawler travel device 4 is driven to about 30m away from the tunnel face, and the anchor drill rig 2 is used to start drilling on one side of the tunnel wall, and the fixed anchor rod is installed;

[0038] Then, the pushing mechanism in the installation bin is moved backward: After the anchor rod is installed, the detector body 19 is installed. First, the two first-level hydraulic cylinders 22 are recovered, and the first-level push plate 15 is moved backward toward the rear baffle 16 until the connecting port between the storage bin 17 and the installation bin 12 is fully opened, and the second-level hydraulic cylinder 14 and the second-level push plate 13 are driven to move backward, and then the second-level hydraulic cylinder 14 is recovered to move the second-level push plate 13 backward, and finally the first-level push plate 15 is fitted with the second-level push plate 13, and both are located as shown in the figure. Figure 6 At the position of point A shown, a passage is formed between the storage bin 17, the installation bin 12 and the installation outlet 11;

[0039] Secondly, install the detector body 19: the initial position of the swing handle 53 is clamped in the locking groove 50 at the bottom of the storage bin 17; pull the swing handle 53 out of the locking groove 50 into the through groove 51 and slide it up and down. At this time, the compression spring 21 slowly restores part of the elastic force, so that the connecting rod 52 and the supporting plate 20 also move upward together. The detector body 19 at the upper end of the storage bin 17 enters the installation bin 12 under the action of the compression spring 21, and the installation bin 12 can only enter one detector body 19 at a time. Since the supporting plate 20 is arranged at an angle, the detector body 19 is placed at an angle in the storage bin 17. When the first-level push plate 15 is extended toward the installation outlet 11, the first-level push plate 15 will start to push from the lower side of the detector body 19 to the highest point and press it down, and the first-level hydraulic cylinder pushes the first-level push plate 15 to Figure 6 The detector body 19 stops at the point B in the installation bin 12, and the point B is the highest point of the detector body 19 in the storage bin 17. At this time, the detector body 19 at the uppermost end of the storage bin 17 is pressed back into the storage bin 17 to prevent the detector body 19 in the storage bin 17 from popping out. Then, the secondary hydraulic cylinder 14 is started to adjust the extension position of the secondary push plate 13 in the installation bin 12, so that the secondary push plate 13 can push the detector body 19 out of the installation outlet 11. A strong magnetic material is used on one side of the detector body 19, so that it is firmly adsorbed on the fixing seat of the anchor rod.

[0040] Finally, after the above steps are completed, the above steps are repeated again with a horizontal interval of about 1.5m, and the anchor rods and the detector body 19 are installed in sequence. When the detector body 19 is installed next time, the secondary hydraulic cylinder 14 is first started to drive the secondary push plate 13 to the primary push plate 15 (i.e. Figure 6 Then the first hydraulic cylinder 22 drives the first push plate 15, the second push plate 13, and the second hydraulic cylinder 14 to move to the point B of the Figure 6 Move to point A in the middle, so that the next detector body 19 moves upward to the installation chamber 12, and then repeat the installation steps of the above detector body 19.

[0041] The above detector body 19 is installed eight times on the same horizontal line.

[0042] When it is necessary to load the detector body 19 into the storage bin 17, first, pull the swing handle 53 from the locking groove 50 into the through groove 51 and slide it up and down, pull the swing handle 53 downward along the through groove 51, so that it drives the connecting rod 52 and the supporting plate 20 to move toward the bottom of the storage bin 17. At this time, the compression spring 21 is continuously compressed as the supporting plate 20 moves downward, so that space for accommodating the detector body 19 is reserved at the upper end of the storage bin 17, and then the detector bodies 19 are placed one by one into the storage bin 17 through the discharge port 18, that is, the loading of the detector body 19 is completed, and finally the swing handle 53 is snapped into the corresponding locking groove 50.

[0043] When the detector body 19 is in use, an anchor rod is fixed again at the position of the advanced detector body 5 to 7 m away from the farthest end of the tunnel face. The root of the anchor rod protrudes 0.6 m to 1 m from the cave wall, which is the blasting point of the advanced geological detector body.

[0044] The transmitting signal source is pasted on a hammer, and the hammer is used to hit the blasting point. Different sound wave signals will be received at the advanced geological detector body 19. The geological conditions in front of the face can be obtained by analyzing the different sound wave signals with data analysis software.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
