Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to an arch-anchor-grouting combined operation trolley. Background Technique

[0002] The arch-anchor trolley in tunnel construction is a mechanical equipment specially designed for tunnel support, mainly used for the initial support after tunnel excavation. Especially under the condition of soft surrounding rock, it can quickly and effectively complete tasks such as arch frame installation, bolt construction, and grouting. The design of the arch-anchor trolley integrates multiple functions, which can significantly improve the construction efficiency and ensure the safety of operators at the same time. However, most of the existing arch-anchor trolleys for tunnel construction are dedicated to specific uses. During actual use, the arch-anchor trolley often needs to be fixed at the same position for a long time. At the same time, special material transfer vehicles need to be purchased additionally for the transportation of construction materials, which undoubtedly increases the usage cost of the project.

[0003] In addition, most of the existing arch-anchor trolleys do not have the grouting function. During the grouting operation, the mixing plant outside the tunnel is connected to the working surface through pipelines, and the slurry is provided by the external mixing plant; or the mixing equipment is directly moved into the tunnel. As the tunnel construction operation progresses, the mixing equipment also needs to move forward continuously. These two methods have many inconveniences in actual operation. Since the ground conditions are often not flat during tunnel construction, additional time is required for placement and leveling every time the mixing equipment is moved, which not only increases the complexity of the operation but also seriously slows down the construction progress, resulting in a significant reduction in the overall operation efficiency. Therefore, developing a multi-functional arch-anchor trolley that can integrate the mixing and grouting functions can not only solve the above problems but also further improve the construction efficiency and safety.

[0004] Chinese Patent (Publication No.: CN217925939U) discloses an arch-anchor trolley with a grouting function; a concave groove area is arranged on the side of the vehicle body of this patent, and the grouting machine is embedded in the groove area, and the grouting machine is connected to the vehicle body through a lifting component; however, this patent is also dedicated to specific uses, and special material transfer vehicles need to be purchased additionally for the transportation of construction materials; it is found during actual use that since the grouting machine is embedded in the side of the vehicle body, it is not convenient for feeding operation and is inconvenient to use.

[0031] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or positional relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation.

[0032] Embodiment 1, in combination with the attached Figures 1 to 4 , an arch anchor grouting combined operation trolley, comprising a trailer body 1 and an operation platform 2; the trailer body 1 is provided with a chassis structure that can be correspondingly separated from the bottom of the operation platform 2; as shown in the attached Figure 1 , hydraulic support legs 4 for lifting and supporting the operation platform 2 are provided at the four corner ends of the operation platform 2; when it is necessary to separate the operation platform 2 from the trailer body 1, first withdraw the mixing grouting device 3 from the bottom of the operation platform 2 so that the mixing grouting device 3 avoids the wheels of the trailer body 1; then lift and support the operation platform 2 through the four hydraulic support legs 4, and the operation platform 2 can be separated from the trailer body 1; the operator can use the trailer body 1 to transport the materials required for tunnel construction, with dual uses, improving the practicability.

[0033] Combination mechanism of the trailer body 1 and the operation platform 2:

[0034] The chassis structure includes a support frame 1-1 fixedly connected to the top of the girder of the trailer body 1. Above the support frame 1-1, there is a support plate 1-3 for supporting the working platform 2. The support plate 1-3 is slidably connected to the support frame 1-1 on the left and right through a sliding mechanism. A guide groove 1-9 is provided at the top of the support plate 1-3, and a plurality of guide posts 1-10 capable of slidingly mating with the groove wall of the guide groove 1-9 are provided at the bottom of the working platform 2. Through the cooperation of the guide posts 1-10 and the guide groove 1-9, the operator is guided to drive the trailer body 1 into the bottom of the working platform 2, so that the support plate 1-3 can coincide with the working platform 2, facilitating the alignment of the central axis of the working platform 2 with the central axis of the trailer body 1 and avoiding the deviation of the center of gravity of the trailer body 1.

[0035] To reduce the operation difficulty when the trailer body 1 is combined with the working platform 2, two guide posts 1-10 are provided at the bottom of the working platform 2, and the two guide posts 1-10 are respectively located at both ends of the bottom of the working platform 2.

[0036] To avoid serious hard friction between the guide posts 1-10 and the groove wall of the guide groove 1-9 when the trailer body 1 is combined with the working platform 2, rollers 1-11 are rotatably connected to the column bodies of the guide posts 1-10. That is, during the process of the trailer body 1 driving the support plate 1-3 into the bottom of the working platform 2, the rollers 1-11 roll along the groove wall of the guide groove 1-9, effectively reducing the friction between the guide posts 1-10 and the groove wall of the guide groove 1-9.

[0037] When the working platform 2 needs to be transported by the trailer body 1, the operator can drive the trailer body 1 into the bottom of the working platform 2. Before the trailer body 1 enters the bottom of the working platform 2, the guide groove 1-9 needs to be aligned with the guide posts 1-10. One end of the guide groove 1-9 corresponding to the tail of the trailer body 1 is in a trumpet-shaped structure, which can facilitate the smooth entry of the guide posts 1-10 into the guide groove 1-9.

[0038] During the process of the trailer body 1 entering the bottom of the working platform 2, if the axis of the length direction of the guide groove 1-9 is not parallel to the axis of the length direction of the working platform 2, the second guide post 1-10 cannot enter the guide groove 1-9. At this time, the operator only needs to adjust the driving direction of the trailer body 1, and the support plate 1-3 can move left and right adaptively under the action of the sliding mechanism. On the one hand, it avoids applying a large lateral force to the working platform 2, and on the other hand, it avoids the operator having to drive the trailer body 1 out of the working platform 2 multiple times to adjust the direction of the trailer body 1, effectively reducing the operation difficulty when the trailer body 1 is combined with the working platform 2 and improving the operation efficiency.

[0039] It should be noted that before the trailer body 1 enters the bottom of the working platform 2, it is necessary to adjust the height of the working platform 2 through the hydraulic support legs 4 so that the bottom of the working platform 2 is higher than the top surface of the support plate 1-3, and the bottom end of the guide column 1-10 is located in the guide groove 1-9 to prevent the guide column 1-10 from slipping out of the guide groove 1-9 and losing its guiding function.

[0040] Combined with Figure 3 and 4 The sliding mechanism includes a support beam 1-2 arranged at the top of the support frame 1-1, and a gap is left between the top of the support beam 1-2 and the bottom of the support plate 1-3; a plurality of guide rods 1-4 are movably connected to the support beam 1-2 at intervals, and the two ends of the guide rods 1-4 are respectively fastened to the bottom of the working platform 2 through connecting plates 1-5, and the guide rods 1-4 are corresponding to the rod bodies between the support beam 1-2 and the connecting plates 1-5. A spring 1-6 is provided on the rod body between the guide rods 1-4 and the connecting plates 1-5. When the connecting plates 1-5 are not subjected to external forces, the connecting plates 1-5 can automatically align with the support frame 1-1 left and right under the action of the springs 1-6; when the guide column 1-10 applies lateral force to the connecting plates 1-5, the connecting plates 1-5 can move left and right along the axial direction of the guide rods 1-4 and the support frame 1-1.

[0041] A plurality of support wheels 1-7 are provided at intervals on both sides of the beam body of the support beam 1-2 at the bottom of the support plate 1-3, which are in rolling contact with the support frame 1-1. That is, the support plate 1-3 can directly apply its own gravity and bearing force to the support frame 1-1 through the support wheels 1-7, so as to prevent the guide rod 1-4 from being bent due to a large bending moment;

[0042] A telescopic rod 1-8 is installed between the support beam 1-2 and the support plate 1-3 to align the support plate 1-3 with the support frame 1-1; when the support plate 1-3 overlaps with the working platform 2, there may be a left-right misalignment between the support plate 1-3 and the support frame 1-1. At this time, the hydraulic legs 4 are controlled to shorten so that the working platform 2 falls on the support plate 1-3, and the hydraulic legs 4 are ensured to be completely off the ground. The support plate 1-3 is driven along the guide rod 1-4 by the telescopic rod 1-8 until the support plate 1-3 overlaps with the support frame 1-1, so that the central axis of the working platform 2 is aligned with the central axis of the trailer body 1;

[0043] It should be noted that, when the trailer body 1 enters the bottom of the working platform 2, the telescopic rod 1-8 is in a free telescopic state when necessary to avoid interference with the adaptive movement of the support plate 1-3.

[0044] The positions of the support frame 1-1 and the support plate 1-3 corresponding to the stirring grouting device 3 are both provided with a clearance notch, as shown in the attached Figure 1 and 2As shown, when the working platform 2 is transported, the stirring and grouting device 3 can be pushed into the bottom of the working platform 2, and the stirring and grouting device 3 can enter the clearance gap area, thereby reducing the overall width and making it easier for the operator to drive the trailer body 1 through the narrow area.

[0048] When grouting is required, the mounting frame 3-2 can be pulled out through the telescopic slide rail 3-1, and then the stirring device can be pulled out, and the mortar can be stirred by the stirring device. After the mortar stirring is completed, the gate valve 3-4 is opened to allow the mortar in the stirring device to flow into the screw conveyor 3-3, and the outlet of the screw conveyor 3-3 is connected to the grouting hose to carry out the grouting operation; when the working platform 2 needs to be moved, the stirring device can be retracted to the bottom of the working platform 2 through the telescopic slide rail 3-1. Figure 5 As shown, a side box which can be pulled out together with the stirring and grouting device 3 is connected to the work platform 2 corresponding to the stirring and grouting device 3, and tools or grouting hoses can be stored in the side box.

[0049] Combined with Figure 6 The stirring device comprises a box body 3-5 with an open top, and a stirring shaft 3-6 with stirring blades is rotatably connected to the bottom of the box body 3-5, and the stirring shaft 3-6 is arranged horizontally, which can effectively reduce the overall height of the stirring device while ensuring the stirring efficiency, so that it can be easily installed at the bottom of the working platform 2; a driving device 3-7 for driving the stirring shaft 3-6 is arranged outside the box body 3-5, and the driving device 3-7 can be an electric motor or a hydraulic motor.

[0050] In order to further reduce the overall height of the stirring device and avoid splashing of mortar during stirring, an anti-splashing device is provided on the top of the box body 3-5, such as the attached Figure 7 and 8As shown, the anti-splashing device comprises a frame 3-8 connected to the top of the box body 3-5, two inclined baffles 3-9 are arranged at intervals on both sides of the frame 3-8, and an inverted V-shaped baffle 3-10 is arranged in the middle of the frame 3-8, and the bottom edge of the inverted V-shaped baffle 3-10 extends between the upper and lower inclined baffles 3-9 on the corresponding side; that is, the purpose of anti-splashing is achieved by the staggered arrangement of the inverted V-shaped baffle 3-10 and the inclined baffle 3-9, so that the mortar can be prevented from splashing while reducing the height of the box body 3-5; at the same time, there is no need to remove the anti-splashing device when feeding into the box body 3-5, which is convenient for operation;

[0051] The frame 3-8 is correspondingly plugged into the top of the box body 3-5, and a limiting retaining edge 3-11 is provided outside the frame 3-8, that is, the frame 3-8 is detachably connected to the top of the box body 3-5, and the operator can regularly remove the anti-splash device to clean the mortar adhered to the anti-splash device.

[0052] In order to further improve the uniformity of the mortar, a vibrator 3-12 is provided at the bottom of the box 3-5, that is, the vibrator 3-12 can be turned on during the mixing operation to improve the uniformity of the mortar and improve the mixing efficiency.

[0053] A screen is provided on the top of the stirring device to prevent large particles or foreign matter from entering the stirring device and accidentally blocking the gate valve 3-4 or the screw conveyor 3-3 during the grouting operation.
