Description

Technical Field

[0001] This application relates to the field of anchor bolt trolley technology, and in particular to an anchor cable trolley. Background Technology

[0002] Anchor cable trolleys are fully mechanized equipment used in underground mining, tunnel excavation, and other engineering projects for deep-hole drilling and anchor cable support. The support function of anchor cables is crucial; in addition to suspending the surrounding rock like anchor bolts, they also compress and reinforce the surrounding rock. Anchor cables have high preload, large anchoring force, and deep anchoring, penetrating directly into the main roof. This tightly connects the secondary bearing layer formed by anchor bolt support with the main bearing layer of the surrounding rock, improving the stability of the secondary bearing layer. The large preload applied to the anchor cables compresses and seals the bedding and joint fissures in the rock strata, increasing friction between discontinuous layers and improving the overall strength of the surrounding rock. This ensures the safety and stability of the tunnel, preventing roof subsidence and deformation.

[0003] Existing anchor cable trolleys require the anchor cable and grout pipe to be delivered into the anchor cable hole to achieve anchor cable installation; the entire anchor cable operation for a single hole includes drilling, grouting, and anchor cable installation. For example, patent application number 202420959117.1 discloses an anchor cable trolley, including a vehicle body, an anchor cable mechanism, an anchor cable strand mechanism, and a grouting mechanism. The anchor cable mechanism is located at the front end of the vehicle body, and the grouting mechanism is connected to the vehicle body. The grouting mechanism is used to provide grout to the anchor cable mechanism. The anchor cable mechanism includes a working arm and an anchor cable machine head. One end of the working arm is connected to the vehicle body, and the other end is connected to the anchor cable machine head. The anchor cable strand mechanism includes a strand reel and a strand bending assembly. The strand reel is located on the vehicle body, and the strand bending assembly is located on the anchor cable machine head. The anchor cable trolley of this application is equipped with an anchor cable mechanism, a grouting mechanism, and an anchor cable strand mechanism, which enables the anchor cable trolley to perform grouting and anchor cable strand installation functions simultaneously. This means that when grouting and anchor cable installation are performed on drilled holes, no additional equipment is required; only the anchor cable trolley of this application is needed to achieve both grouting and anchor cable installation, which can greatly improve construction efficiency.

[0004] However, the grouting mechanism of the anchor cable trolley in the aforementioned patent requires manual operation of feeding, mixing and grouting in sequence, which is cumbersome and inefficient. Utility Model Content

[0034] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0035] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0036] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, this application discloses an anchor cable trolley, including a vehicle body, a control mechanism, an anchor cable mechanism 4, a drilling mechanism 5, a mixing mechanism, a feeding mechanism, and a water supply mechanism. The control mechanism is located on the vehicle body. The anchor cable mechanism 4 includes a working arm 8 and an anchor cable head 9. One end of the working arm 8 is connected to the vehicle body, and the other end is connected to the anchor cable head 9. The drilling mechanism 5 includes a drilling arm 6 and a drilling propulsion beam 7. One end of the drilling arm 6 is connected to the vehicle body, and the other end is connected to the drilling propulsion beam 7. The mixing mechanism is located on the vehicle body. The mixing mechanism includes a mixing drum 19 and a mixing component disposed in the mixing drum 19; the feeding mechanism includes a storage box 17 disposed on the vehicle body and a feeding component 20, the storage box 17 is used to hold cement dry powder, and the feeding component 20 is used to transport the material in the storage box 17 to the mixing drum 19; the water supply mechanism includes a water tank disposed on the vehicle body and a water delivery component, the water delivery component is used to transport water in the water tank to the mixing drum 19; wherein, the feeding component 20, the mixing component and the water delivery component are electrically connected to the control mechanism respectively. This application integrates multiple functions such as drilling, grout mixing, grouting, and anchor installation onto a single mobile vehicle. Operators no longer need to switch, coordinate, and move between multiple independent pieces of equipment (drilling rig, mixer, grouting pump, etc.), significantly saving time and space and improving construction efficiency. The anchor trolley of this application has a compact structure and is capable of autonomous movement in narrow tunnels and roadways. The feeding component 20 (for conveying dry powder) and the water supply component (for conveying water) are both controlled by a control mechanism, allowing for the automatic addition of water and materials to the mixing drum 19 at timed and quantitative intervals, achieving precise and automatic cement-water ratio. Furthermore, this application eliminates the need for a suspended platform, further simplifying the structure and providing operators with better visibility without obstruction.

[0037] Furthermore, the mixing mechanism also includes a weighing component, which is electrically connected to the control mechanism. The weighing component is located below the mixing drum 19 and is used to weigh the material in the mixing drum 19 to accurately determine the amount of material in the mixing drum 19. The weighing component is a weighing sensor. The feeding component 20 is a screw conveyor. The screw conveyor includes an inlet end and an outlet end. Its inlet end is connected to the storage tank 17, and its outlet end is connected to the mixing drum 19. Since the feeding component 20 is electrically connected to the control mechanism, the operator can control the opening and closing of the feeding component 20 through the control mechanism. Under the control of the control mechanism, the feeding component 20 and the water supply component respectively deliver cement dry powder and water to the mixing drum 19 according to a preset ratio, and the cement dry powder and water are mixed evenly under the stirring of the mixing component. The mixing component is electrically connected to the control mechanism to achieve automatic stirring. The mixing component of this application is a commonly used component in cement mixing in the prior art, and the specific structure of the mixing component is not limited here.

[0038] Furthermore, the water delivery assembly includes a water pump, a water delivery pipe, a solenoid valve, and a flow meter. One end of the water delivery pipe is connected to the water pump, and the other end is connected to the mixing drum 19. The solenoid valve and flow meter are mounted on the water delivery pipe, and the water pump, solenoid valve, and flow meter are electrically connected to the control mechanism. Specifically, the water pump's inlet is connected to a water tank, and its outlet is connected to the water delivery pipe. When the water pump starts, it draws water from the water tank into the water delivery pipe, ultimately reaching the mixing drum 19. The water pump is electrically connected to the control mechanism to achieve automatic water supply. The flow meter monitors the water flow rate delivered to the mixing drum 19, and the data is fed back to the control mechanism in real time to ensure precise and controllable water delivery volume each time. The solenoid valve, through commands from the control mechanism, can instantly open or close the water flow, or adjust its opening to control the flow rate. The flow meter and solenoid valve work together to precisely control the water delivery volume.

[0039] It also includes a grouting mechanism, which includes a mud pipe feed assembly and a mud pipe reel 18. The mud pipe reel 18 is mounted on the working arm 8, and the mud pipe feed assembly is mounted on the anchor cable head 9, so that the anchor cable mechanism 4 can inject mud into the drilled hole. One end of the mud pipe reel 18 is connected to the mixing drum 19, and the other end is connected to the mud pipe feed assembly. The mixing drum 19, the mud pipe reel 18, and the mud pipe feed assembly are arranged sequentially along the extension direction of the working arm 8.

[0040] Please refer to the following: Figures 3-5 As shown, the drilling mechanism 5 further includes a drill rod magazine 16, which is located at one end of the drilling arm 6 near the drilling propulsion beam 7. The drill rod magazine 16 is used to store drill rods and is connected to the drilling propulsion beam 7. When the hole to be drilled exceeds the depth of a single drill rod, the drill rod magazine 16 can be used to complete the series drilling of multiple drill rods to create a deep hole, thus facilitating rapid drilling.

[0041] like Figure 6 As shown, it can be understood that a cab 10 is installed on the vehicle body, and a support frame is installed on the side of the cab 10, with the mixing drum 19 mounted on the support frame. The control mechanism is integrated into the cab 10, and includes a PLC controller and a human-machine interface. The cab 10 is provided with an entrance, through which operators enter the cab 10. A first ladder 12 is provided at the entrance to facilitate operators climbing into the cab 10.

[0042] Please continue reading. Figure 1 and Figure 3As shown, specifically, the vehicle body, from front to back, includes a front frame 1, a middle frame 2, and a rear frame 3. The front frame 1 is equipped with two front wheels 14, and the rear frame 3 is equipped with two rear wheels 15. The middle frame 2 is located between the front wheels 14 and the rear wheels 15. The cab 10 is located on the middle frame 2, the anchor cable mechanism 4 and the drilling mechanism 5 are located on the front frame 1, and the mixing mechanism, the feeding mechanism, and the water supply mechanism are located on the rear frame 3. The mixing drum 19 is located next to the storage box 17. The front frame 1 supports the anchor cable mechanism 4 and the drilling mechanism 5, and the rear frame 3 supports the mixing mechanism, the feeding mechanism, and the water supply mechanism. Because the anchor cable mechanism 4 and the drilling mechanism 5 generate huge reaction forces during operation, the mixing mechanism, the feeding mechanism, and the water supply mechanism are located on the rear frame 3 to form a "counterweight" to balance the huge reaction forces of the front frame 1 during operation and prevent the trolley from tilting and becoming unstable. The cab 10 is positioned between the front frame 1 and the rear frame 3, and the basket originally located on the front frame 1 is removed, making the cab 10 have a wide field of vision and can see both front and rear.

[0043] An operating platform 11 is also installed on the rear frame 3, located on one side of the storage bin 17. A second ladder 13 is installed on the side of the operating platform 11. The operating platform 11 facilitates manual addition of cement powder to the storage bin 17 or maintenance operations, while the second ladder 13 facilitates operators climbing onto the operating platform 11. A first telescopic component is hinged to the bottom of the operating platform 11, which is used for folding or unfolding the operating platform 11. The operating platform 11 unfolds when needed and folds up when the trolley is moving, saving space and making the trolley structure more compact to adapt to operations in confined spaces. Specifically, the first telescopic component is a hydraulic cylinder or an electric push rod. The specific connection method between the first telescopic component and the operating platform 11 is existing technology and will not be described in detail here.

[0044] It should be noted that the front frame 1 is provided with a first connecting part and a second connecting part, which are arranged vertically at intervals along the axial direction of the vehicle body, with the first connecting part located above the second connecting part. The drilling arm 6 is rotatably connected to the front frame 1 through the first connecting part, and the working arm 8 is rotatably connected to the front frame 1 through the second connecting part. The vertical arrangement of the working arm 8 and the drilling arm 6 lowers the center of gravity of the trolley and improves stability; it also avoids spatial interference caused by the lateral expansion of the working arm 8 and the drilling arm 6, making it suitable for operation in narrow roadways or tunnels; in addition, the angle and position of the working arm 8 and the drilling arm 6 can be flexibly adjusted to simultaneously handle anchor cable holes of different heights and angles on the roof and sidewalls, making it more adaptable to complex geological conditions such as faults and fracture zones.

[0045] Understandably, the drilling mechanism 5 also includes a swing assembly. The rear end of the swing assembly is connected to the front end of the drilling arm 6, and the front end of the swing assembly is connected to the drilling propulsion beam 7. That is, the drilling arm 6 is connected to the drilling propulsion beam 7 through the swing assembly. Specifically, the swing assembly includes a swing motor and a swing cylinder. The front end of the drilling arm 6 is connected to the rear end of the swing motor, and the drilling propulsion beam 7 is connected to the upper end of the swing motor. The swing motor is used to drive the drilling propulsion beam 7 to rotate 360 ​​degrees horizontally relative to the drilling arm 6. One end of the swing cylinder is connected to the swing motor, and the other end is connected to the drilling propulsion beam 7. The swing cylinder drives the drilling propulsion beam 7 to swing horizontally relative to the drilling arm 6 to adjust the position of the drilling propulsion beam 7. The working arm 8 includes an inner arm and an outer arm. The inner arm and the outer arm are connected by a telescopic cylinder. The telescopic cylinder is used to drive the inner arm to extend and retract relative to the outer arm. One end of the outer arm is connected to the vehicle body, and the mud hose reel 18 is connected to the side of the outer arm.

[0046] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
