Description

Technical Field

[0001] This invention belongs to the field of building construction, and specifically relates to an excavation trolley device. Background Technology

[0002] When excavating tunnels, there are generally two methods: the full-face method and the bench method. Before excavation, construction workers will conduct geological sampling and testing of the area to be excavated to determine the approximate geological structure of the area. The full-face method refers to excavating the entire tunnel cross-section in one go, which is suitable for areas with stable geology and solid surrounding rock, and has high construction efficiency. The bench method, on the other hand, involves dividing the tunnel cross-section into multiple horizontal benches according to the strength of the surrounding rock, and excavating step by step. It is suitable for areas with complex geological conditions and poor surrounding rock stability, ensuring construction safety. For some areas with more complex geological conditions, in order to ensure safety and construction efficiency, the full-face method and the bench method need to be used alternately when excavating tunnels.

[0003] When using the step method for construction, it is necessary to frequently change the excavation platform to different heights to change the excavation height. The excavation platform of different heights needs to be moved to the outside of the tunnel or at the transfer point for replacement, which reduces the efficiency of tunnel excavation. Summary of the Invention

[0004] This invention discloses an excavation trolley device. By setting up a height-adjustable operating platform, during step excavation, the height of the operating platform can be changed to achieve step-by-step excavation without the need to change the excavation trolley, making construction convenient.

The operating platform includes: a lifting plate that is height-adjustably installed between the pair of main body plates; a balance plate that is angle-adjustably installed above the lifting plate; a standing plate that is movable relative to the balance plate and installed on the upper surface of the balance plate; and a balancing mechanism fixed to the upper surface of the lifting plate for adjusting the angle of the balance plate to keep the balance plate horizontal, thereby keeping the standing plate horizontal.

[0006] A further improvement of the present invention is that the balancing mechanism includes: at least three balancing legs, each balancing leg including a first telescopic rod fixed to the upper surface of the lifting plate, a hinge fixed to the top of the first telescopic rod, and a controller for independently controlling the extension and retraction of each first telescopic rod, the hinge being rotatably connected to the balancing plate; the balancing legs are divided into two groups, the two groups of balancing legs supporting the balancing plate one in front of the other, the balancing plate having a movable groove, wherein the hinge at the top of one group of balancing legs is slidably installed in the movable groove to provide a space for the group of balancing legs to move when the first telescopic rod extends and retracts.

[0007] A further improvement of the invention is that it also includes a level fixed to the standing board, the level being connected to the controller, the controller selectively controlling the extension or retraction of one or more of the first telescopic rods based on the readings of the level.

[0008] A further improvement of the present invention is that the bottom of the standing plate is equipped with a movable wheel, and the upper surface of the balance plate is provided with a guide groove extending in the front-back direction, and the movable wheel is limited to the guide groove and moves along the guide groove.

[0009] A further improvement of the present invention is that the upper surface of the standing board is covered with an anti-slip surface.

[0010] A further improvement of the present invention is that it also includes a lifting mechanism for adjusting the height of the lifting plate, the lifting mechanism comprising: a pair of lifting slots respectively opened vertically on the inner side of a pair of main plates; a pair of lifting blocks respectively fixed to both sides of the lifting plate, the pair of lifting blocks being respectively movable and limited within the pair of lifting slots; a pair of lifting motors, the pair of lifting motors being respectively fixed to the ends of the pair of lifting slots; a pair of lifting screws, the pair of lifting screws being respectively coaxially fixed to the drive ends of the pair of lifting motors and extending through the lifting slots, a pair of lifting screw holes respectively opened vertically on the pair of lifting blocks, the pair of lifting screws being respectively screwed into the pair of lifting screw holes.

The grooving mechanism includes: a movable plate installed between a pair of main plates and movable back and forth relative to the pair of main plates, the movable plate being located above the standing plate; and a drill bit installed in front of the movable plate for grooving.

[0013] A further improvement of the present invention is that it also includes a pressure detection mechanism for detecting the pressure of the drill bit during drilling to detect the hardness of the surrounding rock at the excavation face. The pressure detection mechanism includes: a receiving groove located in front of the moving plate and extending into the moving plate; a pressure sensor fixed in the receiving groove; a sensing element connected to the front end of the pressure sensor at the tail end of the drill bit; and the front end of the drill bit extending out of the receiving groove.

Furthermore, if a switch to the full-face method is required during excavation, there is no need to change the tire sidewalls; only the operating platform needs to be adjusted to an appropriate height.

[0015] like Figure 1 , Figure 2 , Figure 5 , Figure 11 As shown, the present invention provides an excavation trolley device, comprising: A pair of main body panels 1, the pair of main body panels 1 are arranged vertically and are parallel to each other; The operating platform 3 is located at the front end of a pair of main body plates 1. The operating platform 3 includes: a lifting plate 41 that is height-adjustably installed between the pair of main body plates 1; a balance plate 31 that is angle-adjustably installed above the lifting plate 41; a standing plate 32 that is movable relative to the balance plate 31 and installed on the upper surface of the balance plate 31; and a balancing mechanism fixed to the upper surface of the lifting plate 41 for adjusting the angle of the balance plate 31 so that the balance plate 31 remains horizontal, thereby keeping the standing plate 32 horizontal.

[0016] like Figure 5 , Figure 11 As shown, the balancing mechanism includes at least three balancing legs. Each balancing leg includes a first telescopic rod 313 fixed to the upper surface of the lifting plate 41, a hinge 312 fixed to the top of the first telescopic rod 313, and a controller for independently controlling the extension and retraction of each first telescopic rod 313. The hinge 312 is rotatably connected to the balancing plate 31. The balancing legs are divided into two groups, with the two groups of balancing legs supporting the balancing plate 31 one in front of the other. The balancing plate 31 has a moving groove 314. The hinge 312 at the top of one group of balancing legs is slidably installed in the moving groove 314 to provide a space for the group of balancing legs to move when the first telescopic rod 313 extends or retracts.

[0017] Preferably, in this embodiment, a level fixed to the standing board 32 is also included. The level is connected to the controller, and the controller selectively controls the extension or retraction of one or more first telescopic rods 313 by means of the reading of the level.

[0018] Preferably, in this embodiment, as Figure 5 As shown, the hinge 312 is rotatably connected to the standing plate 32 via the hinge shaft 311.

[0019] In this embodiment, as Figure 5 As shown, a total of four balance legs are installed, and the four balance legs are divided into two groups of two. The hinge 312 of one group of balance legs is slidably limited in the moving groove 314. Specifically, the end of the hinge shaft 311 of the hinge 312 of the group of balance legs is fixed with a hinge block 316. A hinge block slot 315 is also provided in the moving groove 314. The hinge block 316 is movably limited in the hinge block slot 315, thereby realizing the slidable limitation of the hinge 312 in the moving groove 314.

[0020] like Figure 3 As shown, the bottom of the standing plate 32 is equipped with a moving wheel 36, and the upper surface of the balance plate 31 is provided with a guide groove extending in the front-back direction. The moving wheel 36 is confined within the guide groove and moves along the guide groove.

[0021] In this embodiment, as Figure 3 As shown, the guide groove includes a third guide groove 39 formed on the upper surface of the balance plate 31, a first guide groove 35 communicating with the third guide groove 39, and a second guide groove 35 formed on both sides of the standing plate 32. The standing plate 32 is entirely housed in the third guide groove 39. The moving wheel 36 rotates around the wheel axle 37, which is confined within the second guide groove 35. The moving wheel 36 rotates along the first guide groove 35. By providing the guide groove, the movement direction of the standing plate 32 can be limited.

[0022] In this embodiment, as Figure 3 As shown, a protective body 34 is provided at the edge of the third guide groove 39. By providing the protective body 34, the standing plate 32 can be prevented from moving to the outside and detaching from the upper surface of the balance plate 31.

[0023] If the ground inside the tunnel tilts during the excavation process, the standing plate 32 will also tilt, which may make it difficult for construction workers to stand on the tilted standing plate 32. By setting up a balance plate 31 and a balancing mechanism, when the level instrument detects that the standing plate 32 is not level, the balancing mechanism will adjust the standing plate 32 to be level, making it easier for construction workers to stand.

[0024] like Figure 3As shown, the upper surface of the standing board 32 is covered with an anti-slip surface 33. By setting the anti-slip surface 33, the friction of the surface of the standing board 32 can be increased, reducing the possibility of construction workers slipping on the standing board 32.

[0025] Better, such as Figure 8 , Figure 9 As shown, it also includes a lifting mechanism for adjusting the height of the lifting plate 41. The lifting mechanism 4 includes: a pair of lifting grooves 44 respectively opened in the inner side of a pair of main plates 1 along the vertical direction; a pair of lifting blocks 45 respectively fixed on both sides of the lifting plate 41, the pair of lifting blocks 45 being respectively able to be lifted and limited within the pair of lifting grooves 44; a pair of lifting motors 42, the pair of lifting motors 42 being respectively fixed at the ends of the pair of lifting grooves 44; a pair of lifting screws 43, the pair of lifting screws 43 being respectively coaxially fixed to the drive ends of the pair of lifting motors 42 and being arranged throughout the lifting grooves 44, a pair of lifting screw holes respectively opened in the vertical direction on the pair of lifting blocks 45, and the pair of lifting screws respectively being screwed into the pair of lifting screw holes.

[0026] Preferably, in this embodiment, each main body plate 1 is provided with two lifting grooves 44.

[0027] Preferably, in this embodiment, as Figure 1 As shown, a pair of main body plates 1 are equipped with base wheels 52 at their bottom.

[0028] like Figure 1 As shown in this embodiment, a pair of main body plates 1 are respectively fixed with support plates 5 on the bottom inner side. The support plates 5 are long strips, and a number of buffer seats 51 are fixed at the bottom of the support plates 5. Each buffer seat 51 is equipped with a base wheel 52 at the bottom. By setting the buffer seats 51, the overall weight of the equipment can be buffered and then transferred to the base wheel 52. By setting the base wheel 52, it is convenient for the equipment to move to the tunnel excavation face and can continuously move its position during the excavation process.

[0029] like Figure 1 , Figure 7 , Figure 8 , Figure 10 As shown, this example also includes a grooving mechanism 2 for grooving the upper part of the excavation face to facilitate subsequent tunnel excavation by workers. The grooving mechanism 2 includes: a movable plate 21 installed between a pair of main plates 1 and movable back and forth along the tunnel excavation direction, the movable plate 21 being located above the operating platform 3; and a drill bit 211 installed in front of the movable plate 21 for grooving.

[0030] In this embodiment, the movable plate 21 can also serve as a protective plate, located above the operating platform 3, to protect the construction personnel on the operating platform 3.

[0031] Preferably, in this embodiment, as Figure 2 , Figure 4 , Figure 8 , Figure 10 As shown, a pair of main plates 1 each have a limiting groove 212 on their upper surface. The limiting groove 212 is set along the excavation direction. A moving plate motor 214 is fixed at the end of each limiting groove 212. A moving plate threaded rod 213 is fixed at the drive end of each moving plate motor 214. The moving plate threaded rod 213 is set along the direction of the limiting groove 212 and is set inside the limiting groove 212. The moving plate 21 is arc-shaped. A pair of limiting bodies 215 are fixed at the bottom of both sides of the moving plate 21. A threaded hole for the moving plate threaded rod 213 to pass through is opened along the length of the limiting body 215. The moving plate threaded rod 213 passes through the threaded hole. The limiting body 215 and the moving plate threaded rod 213 are screwed together and the moving plate threaded rod 213 is driven to rotate by the drive end of the moving plate motor 214 to drive the movement of the moving plate 21. The start and stop of the moving plate motor 214 and the rotation direction of the drive end are adjustable.

[0032] By setting up the grooving mechanism 2, the drill bit 211 can first groove, and after grooving, the construction personnel can carry out further excavation on the basis of the grooving, which improves the construction efficiency. Preferably, as shown in 7 of this embodiment, it also includes a pressure detection mechanism for detecting the pressure of the drill bit 211 when the drill bit 211 is digging, so as to detect the hardness of the surrounding rock at the excavation face. The pressure detection mechanism includes: a receiving groove 28 opened in front of the moving plate 21 and extending into the moving plate 21; a pressure sensor 27 fixed in the receiving groove 28, and the tail end of the drill bit 211 is connected to the sensing element at the front end of the pressure sensor 27 and extends out of the receiving groove 28.

[0033] In this example, as Figure 6 , Figure 7 As shown, a connecting plate 22 is fixed to the inner side of one of the main plates 1. The end of the connecting plate 22 extends to the middle of the moving plate 21. A first motor 23 is fixed on the upper part of the connecting plate 22. A second telescopic rod 24 is fixed to the driving end of the first motor 23. A connecting rod 26 is fixedly connected to the telescopic end of the second telescopic rod 24. A receiving groove 28 is opened at the end of the connecting rod 26. A pressure sensor 27 is fixedly connected to the connecting rod 26 in the receiving groove 28. A limiting block 29 that slides with the receiving groove 28 is fixedly connected to the end of the pressure sensor 27. A drill motor 210 is fixedly connected to the end of the limiting block 29. A drill bit 211 is fixedly connected to the drive shaft end of the drill motor 210.

[0034] By setting up a pressure detection mechanism, the moving plate 21 is moved to the excavation face, and the drill bit 211 is used to make a groove. During the process of the drill bit 211 making a groove, the hardness of the soil in front can be judged according to the reading of the pressure sensor 27, and the step method or the full-section method can be selected according to the hardness. If the step method is selected, the number of steps when excavating the step method can also be determined according to the hardness.

[0035] Better, such as Figure 1 As shown, in this embodiment, a plurality of connecting rods 11 are also connected between a pair of main body plates 1. By setting the connecting rods 11, the connection strength between a pair of main body plates 1 can be enhanced. When setting the connecting rods 11, they need to be staggered from the moving plate 21 and the operating platform 3 to prevent them from obstructing the forward and backward movement of the moving plate 21 and the forward and backward movement or lifting and lowering of the operating platform 3.

[0036] In this embodiment, the device is moved to the location to be constructed inside the tunnel by the base wheel 52 at the lower end of the support plate 5. When the device is moved to the tunnel with a certain slope, a level is set at the upper end of the workbench 32. The level is connected to the telescopic rod 313 through the controller. When the level detects a tilt, the level controls the extension and retraction of the four first telescopic rods 313 to keep the balance plate 31 horizontal, thereby keeping the standing plate 32 horizontal as well. This ensures that construction workers can stand horizontally in the tunnel with a slope, making it convenient for workers to use drilling machines and other devices for excavation.

[0037] Before construction, two moving plate motors 214 are started, driving the moving plate threaded rod 213 to rotate. The moving plate threaded rod 213, in turn, drives the limiting body 215 to move forward, thereby moving the protective plate 21 to the area to be excavated. At the same time, the first motor 23 and the drill bit motor 210 are started. While the first motor 23 drives the second telescopic rod 24 to rotate, the second telescopic rod 24 extends and retracts to ensure that the connecting rod 26 is always within the arc groove 25. Then, the drill bit motor 210 drives the drill bit 211 to rotate, slotting the upper part of the excavation face, which facilitates subsequent tunnel excavation by workers and improves excavation efficiency. At the same time, when the drill bit 211 contacts the upper arc surface of the excavation section, the pressure sensor 27 can detect the hardness of the upper arc surface of the surrounding rock, thereby determining the number of steps when using the step method for excavation, preventing operation on surrounding rock with rapidly decreasing hardness during full-section construction, and improving the safety of the device.

[0038] Based on the pressure sensor 27 readings and the geological structure measured before construction, several lifting motors 42 are activated. Each lifting motor 42 drives a lifting screw 43 to rotate, which in turn moves the lifting block 45 up and down, thereby moving the lifting plate 41 to a suitable position. Under the premise of ensuring safety, the number of steps is reduced or the full-face method is used for excavation, which speeds up the efficiency of tunnel excavation. When the lifting plate moves the standing plate 32 to a suitable height, the construction workers move the standing plate 32 using the moving wheels 36 while excavating. When the standing plate 32 moves to the construction distance, the construction workers excavate the excavation face. After the excavation is completed, the work platform 32 is moved back to the initial position. At this time, the lifting plate 41 moves the standing plate 32 to the next step, and the construction steps are repeated until the tunnel excavation is completed.

[0039] The present invention has the following beneficial effects: 1. By setting up the balancing mechanism 3, the standing plate 32 can remain horizontal in the inclined tunnel, making it convenient for construction workers to stand on the standing plate 32.

[0040] 2. The grooving mechanism 2 is used to groove the upper part of the excavation face, which facilitates the subsequent excavation of the tunnel by workers and improves the excavation efficiency. At the same time, when the drill bit 211 contacts the upper arc surface of the excavation section, the pressure sensor 27 can detect the hardness of the upper arc surface of the surrounding rock, thereby determining the number of steps when using the step method for excavation. This prevents the operation on the surrounding rock with rapidly decreasing hardness during the full-section method construction and improves the safety of the device. 3. By setting up a lifting mechanism, the operating platform 3 can be driven to a suitable position, reducing the number of steps or excavating using the full-section method while ensuring safety. This eliminates the need to change different excavation trolleys, thus speeding up the tunnel excavation efficiency.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
