Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a drainage trenching device for building engineering. Background Technology

[0002] Building construction refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipes, and equipment. When installing and laying drainage systems, the construction team needs to first create grooves in the building surface to facilitate pipe placement.

[0003] Traditional trenching operations rely heavily on manual hand-held cutting equipment or small machinery, which has several drawbacks: First, manual operation has low precision, making it difficult to uniform the depth, width, and straightness of the trench, affecting the quality of subsequent pipeline installation; second, unidirectional driven mechanical trenching equipment has poor adjustment flexibility, making it impossible to quickly achieve precise adjustments in the horizontal, vertical, and depth directions, resulting in low construction efficiency when facing complex terrain (such as corners and sloping areas); third, equipment movement relies heavily on manual pushing and pulling, and with the support of heavy cutting components, turning is difficult and stability is poor, making it easy for improper operation to cause trench displacement or equipment tipping over. Utility Model Content

A cutting assembly 8 is mounted at the output end of the rotary motor 7. A wheel set 9 is mounted at the bottom of the working frame 1, and a steering assembly 10 is mounted at one end. A water spraying assembly 11 is mounted on the upper surface of the working frame 1 on one side of the transverse drive assembly 2.

[0026] The transverse drive assembly 2 includes a first lead screw 201 rotatably connected between the two ends of the working frame 1 and a guide rod 202 fixedly connected. A first motor 203 is provided on the outer side of one end of the working frame 1. The output end of the first motor 203 is connected to the first lead screw 201. The support frame 3 is connected to the first lead screw 201 through a ball nut and to the guide rod 202 through a linear bearing.

[0027] The lifting drive assembly 4 includes two sets of second motors 401 arranged facing each other at one end of the lifting plate 5. The two sets of second motors rotate synchronously. The output end of the second motor 401 is provided with a gear 402. The inner cavity of the support frame 3 is provided with racks 403 on both sides. The gears 402 and racks 403 mesh and drive each other to generate an upward or downward driving force. The lifting plate 5 is provided with support frames 404 on both sides. The support frames 404 and one end of the lifting plate 5 are provided with first slides 405. The support frame 3 is provided with first slide rails 406 at the corresponding positions of the first slides 405. The first slides 405 and the first slide rails 406 are slidably connected to each other, which ensures that the lifting plate 5 is lifted vertically with high lifting accuracy. It can accurately control the straightness of the groove and overcome the defect of inconsistent straightness in manual grooving.

[0028] The longitudinal drive assembly 6 includes a second lead screw 601 rotatably connected between the two ends of the lifting plate 5. A third motor 602 is provided at one end of the lifting plate 5, and the output end of the third motor 602 is connected to the second lead screw 601. A movable plate 603 is provided on the second lead screw 601, and second slide tables 604 are provided on both sides of the lower surface of the movable plate 603. Second slide rails 605 are provided on the upper surfaces of both ends of the lifting plate 5. The second slide tables 604 are slidably connected to the second slide rails 605. The third motor 602 drives the second lead screw 601 to rotate, and the movable plate 603 moves smoothly on the second slide rails 605 with the help of the second slide tables 604, ensuring the cutting depth and overcoming the defect of uneven grooving depth in manual grooving. A rotary motor 7 is installed on the movable plate 603, and the rotary motor 7 can drive the cutting assembly 8 to rotate flexibly, enabling precise grooving even in complex terrains such as corners, improving the construction efficiency in complex areas, and solving the problem of poor flexibility of traditional unidirectional drive equipment.

[0029] The cutting assembly 8 includes an L-shaped frame 801 connected to the output end of the rotary motor 7. A fourth motor 802 is mounted on the L-shaped frame 801, and a cutting blade 803 is mounted on the output end of the fourth motor 802.

[0030] The wheel assembly 9 includes two sets of drive wheels 901 and two sets of casters 902. The drive wheels 901 are equipped with hub motors to provide power for the movement of the equipment, eliminating the need for manual pushing and pulling and saving manpower. In conjunction with the casters 902, the equipment can move flexibly. The steering assembly 10 includes a rotating plate 1001 rotatably connected to one end of the working frame 1. A connecting rod 1002 is provided on the upper surface of the rotating plate 1001. Both ends of the connecting rod 1002 are connected to the drive wheels 901 through connecting blocks 1003. A traction handle 1004 is rotatably connected to one end of the rotating plate 1001. When the traction handle 1004 is rotated, it drives the rotating plate 1001, the connecting rod 1002 and the connecting block 1003 to move in tandem, so that the drive wheels 901 can turn flexibly. This allows the equipment to easily adjust its direction in narrow areas or corners, solving the problems of difficult steering and poor stability of traditional equipment, and preventing trench deviation or equipment tipping.

[0031] The water spray assembly 11 includes a water tank 1101 disposed on the upper surface of the working frame 1. A water pump 1102 is connected to one corner of the upper surface of the water tank 1101 via a water pipe. A water spray head 1104 is disposed on one side of the protective shell 804 via a clamping block 1103. The water spray head 1104 is connected to the water tank 1101 via a water pipe. The water stored in the water tank 1101 is pressurized by the water pump 1102 and then precisely sprayed onto the cutting blade 803 through the water spray head 1104. This not only suppresses dust diffusion and improves the working environment, but also cools down the cutting blade 803, reduces wear, and extends its service life.
