[0019] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.
[0020] Example 1:
[0021] A municipal engineering road excavation device, referring to Figure 1-4Two support rods 3 are welded to one end of the mobile frame 1. The mobile frame 1 consists of a frame plate 11, two directional wheels 12, and two foot brake casters 13. The two directional wheels 12 are respectively installed on both sides of the frame plate 11, and the two foot brake casters 13 are respectively installed on two corners of the bottom of the frame plate 11. The two directional wheels 12 and the two foot brake casters 13 work together to facilitate the movement of the frame plate 11, while pressing the foot brakes on the two foot brake casters 13 can fix the position of the frame plate 11. A handle bar 81 is fixedly installed on one side of the frame plate 11. Holding the handle bar 81 makes it easy to push the frame plate 11 to move. 11. Two corners of the top edge are welded with fixing rods 82. Both fixing rods 82 are fixed through the handle 81 to enhance the fixation of the handle 81. The lifting plate 2 is movably installed on one side of the two bearing rods 3 through two guide mechanisms 5. The guide mechanism 5 consists of a slide rail 51 and a slide rod 52. The top and bottom ends of one side of the slide rail 51 are welded to one side of the two bearing rods 3 respectively. The slide rod 52 slides inside the slide rail 51. One side of the slide rod 52 is welded to the back edge of the lifting plate 2. During the sliding process of the slide rod 52 inside the slide rail 51, it can guide and limit the lifting plate 2 so that the lifting plate 2 can only be raised and lowered vertically.
[0022] Reference Figure 1-4One of the support rods 3 has a drive system 4 installed at its bottom end for raising and lowering the lifting plate 2. The other support rod 3 has a control switch 67 installed at one end of its top. The other end of the mobile frame 1 has a rechargeable battery 68, a voltage regulator 69, and an inverter 610 installed on its top. The voltage regulator 69 is electrically connected to the rechargeable battery 68 and can regulate the voltage of the rechargeable battery 68. The inverter 610 is electrically connected to the voltage regulator 69 and can convert the current output from the rechargeable battery 68 from DC to AC. The control switch 67 is electrically connected to the inverter 610. The drive system 4 consists of a hollow support cylinder 41, a lifting rod 42, a forward / reverse motor 43, and a threaded rod 44. The top and bottom ends of one side of the hollow support cylinder 41 are welded to one side of the two bearing rods 3 respectively. One end of the lifting rod 42 is welded to the back side of the lifting plate 2. The lifting rod 42 is movably inserted into the interior of the hollow support cylinder 41, and the four sides of the lifting rod 42 are in contact with the inner side of the hollow support cylinder 41. The forward and reverse motor 43 is fixedly installed at the bottom end of the hollow support cylinder 41. The forward and reverse motor 43 is electrically connected to the control switch 67. The power shaft of the forward and reverse motor 43 rotates through the hollow support cylinder 41. The threaded rod 44 is located inside the hollow support cylinder 41. The thread of the threaded rod 44 can achieve self-locking. The self-locking condition of the thread depends on the helix angle, friction coefficient and load of the thread. The thread self-locking condition can be calculated by the following formula: self-locking condition = friction coefficient × tan (helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking, and the outer surface of the threaded rod 44 is coated with lubricating oil. The bottom end of the threaded rod 44 is welded to the end of the power shaft of the forward and reverse motor 43. The bottom end of the lifting rod 42 is provided with an internal thread groove. The lifting rod 42 is threaded onto the outer surface of the threaded rod 44. When the forward and reverse motor 43 is controlled by the control switch 67, the power shaft of the forward and reverse motor 43 drives the threaded rod 44 to rotate. During the rotation of the threaded rod 44, the lifting rod 42 can be helically pushed to rise or fall, thereby adjusting the height of the lifting plate 2.
[0023] Reference Figure 1-4Two buckets 61 are movably mounted on the two corners of the bottom of the lifting plate 2 via two support members 7. The support member 7 consists of a support shaft 71 and a connecting sleeve 72. The connecting sleeve 72 is welded to the top surface of the bucket 61 and movably fitted onto the outer surface of the support shaft 71. One end of the connecting sleeve 72 is welded to one side of the lifting plate 2, thus movably supporting the bucket 61 on one side of the lifting plate 2. A hydraulic impact drill 62 is fixedly installed in the middle of one side of the lifting plate 2. Two mounting blocks 63 are located on one side of the lifting plate 2. Bolts 64 are threaded through the four corners of the two mounting blocks 63, and all eight bolts 64 are threaded to the lifting plate 2. Hydraulic cylinders 65 are movably hinged to the bottom of the two mounting blocks 63. The hydraulic rods of the two hydraulic cylinders 65 are movably hinged to the two buckets 61 respectively. A hydraulic system 66 is installed at one end of the top of the mobile frame 1. The two hydraulic cylinders 65 are respectively connected to two... The hydraulic system 66 is connected to the hydraulic system 66 via two oil pipes. The hydraulic system 66 mainly consists of an oil tank, a hydraulic pump, and control valves. The oil tank stores oil, and the hydraulic pump converts mechanical energy, such as that driven by an electric motor or engine, into hydraulic energy to generate high-pressure oil flow. The control valves regulate the flow rate, pressure, and direction. The control valves in the hydraulic system 66 are connected to the hydraulic impact drill 62 and the hydraulic cylinder 65 via oil pipes, thereby causing the hydraulic impact drill 62 and the hydraulic cylinder 65 to work. During the operation of the hydraulic impact drill 62, the vibratory force generated by its drill bit can break up the road surface. Under the internal oil pressure, the hydraulic rods of the two hydraulic cylinders 65 extend, causing the two buckets 61 to close and remove the road surface debris. A semi-circular arc hole is opened on one side of each of the two buckets 61, which can cover the drill bit of the hydraulic impact drill 62 while it is closing to remove the road surface debris.
[0024] The implementation principle of a municipal engineering road excavation device according to an embodiment of this application is as follows: First, the mobile frame 1 is pushed to the road surface to be excavated. Then, the forward and reverse motor 43 is controlled by the control switch 67 to work. The forward and reverse motor 43 is preferably a TCH(V)22-100-140CB type. The power shaft of the forward and reverse motor 43 drives the threaded rod 44 to rotate. During the rotation of the threaded rod 44, it can spirally push the lifting rod 42 down, thereby adjusting the height of the lifting plate 2 so that the drill bit of the hydraulic impact drill 62 on one side of the lifting plate 2 contacts the road surface. At this time, the hydraulic system 66 controls the hydraulic impact drill 62. During the operation of the hydraulic impact drill 62, the vibration force generated by its drill bit can break up the road surface. After the excavation is completed, the hydraulic system 66 controls the hydraulic impact drill 62 to work. Two hydraulic cylinders 65 extend their hydraulic rods under internal oil pressure, causing the two buckets 61 to close. Once the two buckets 61 are fully closed, the road debris can be removed. Then, the forward and reverse motor 43 is controlled by the control switch 67. The power shaft of 43 drives the threaded rod 44 to rotate. During the rotation of the threaded rod 44, it can spirally push the lifting rod 42 down, thereby adjusting the height of the lifting plate 2. This allows the lifting plate 2 to lift the two buckets 61. Then, the mobile frame 1 is moved to the debris storage area. At this time, the hydraulic system 66 controls the two hydraulic cylinders 65. Under internal oil pressure, the hydraulic rods of the two hydraulic cylinders 65 contract, causing the two buckets 61 to separate, and the debris will fall to the storage area.
