Description

Technical Field

[0001] This utility model relates to the field of wire laying device technology, specifically a wire laying device for construction engineering. Background Technology

[0002] Construction engineering refers to the process of designing, constructing, renovating, and maintaining various types of buildings and structures. It is a comprehensive engineering field involving multiple different types of construction projects, including residential, commercial, industrial facilities, roads and bridges, and water conservancy projects. Construction engineering creates various types of buildings and structures through a series of design, construction, renovation, and maintenance activities to meet people's living and working needs. In construction engineering, the use of surveying and layout devices is for quickly and accurately determining the location and layout of buildings on the construction site.

[0003] As disclosed in the authorization announcement number CN218403047U, a line-laying device for construction engineering includes a base plate, on which two symmetrical support plates are fixedly connected. A rotating block is connected to the support plate via a bearing. A limiting plate is fixedly connected to the rotating block. The limiting plate is in contact with the support plate. A connecting rod is fixedly connected to the limiting plate. A rotating rod is fixedly connected to the rotating block. The rotating rod is rotatably connected to the support plate. A turntable is fixedly connected to the rotating rod. A limiting mechanism is provided on the rotating rod.

[0004] Although it achieves the goal of rotating the limit plate by driving the rotating rod and rotating block through the design of the turntable, and thus allowing the limit plate to rotate for line laying, the limit rod and the limit groove can be connected to each other to limit the rotation of the rotating rod. This can prevent the limit plate from rotating under force when the line laying stops, resulting in the line being laid too long or too short. Through the design of the threaded connection between the positioning stake and the connecting seat, the positioning stake can be moved downward in the vertical direction by rotating it. The positioning stake can be inserted into the ground to position the overall structure. Furthermore, when the positioning stake moves, the round block can also drive the pressure block and the protrusion to move downward, allowing the protrusion to be inserted into the ground, which can further improve the positioning stability of the overall structure.

[0005] However, this does not solve the problem that existing wire feeding devices are generally not conducive to convenient reciprocating movement for wire feeding, are prone to tangling and knotting, are not convenient for adjusting the height for wire feeding, and are not convenient for wire feeding inside pipes, thus affecting the wire feeding effect of the wire feeding device. Utility Model Content

[0006] The purpose of this utility model is to provide a wire laying device for construction engineering, so as to solve the problems mentioned in the background art, which are that the wire laying device is not convenient to move back and forth for conveying and laying, is prone to tangling and knotting, is not convenient to adjust the height for laying, and is not convenient to lay inside the pipeline, thus affecting the wire laying effect.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A wire-laying device for construction engineering includes a base plate and a lifting plate. The lifting plate is disposed on the outside of the base plate, and a support frame is installed at the top of the lifting plate. A hollow shaft is disposed on the outside of the support frame.

The reciprocating threaded rod extends through the support frame to the outside. A first threaded sleeve is fitted on the surface of the reciprocating threaded rod.

[0009] Optionally, the first threaded sleeve is threadedly connected to the reciprocating threaded rod, and a limit rod is movably installed inside the support frame above the reciprocating threaded rod.

[0010] Optionally, the first threaded sleeve is slidably connected to the limiting rod, and a rolling wheel is movably installed on the side wall of the first threaded sleeve.

[0011] Optionally, a power motor is installed inside the base plate, and a first threaded rod is installed at the output end of the power motor. The first threaded rod is movably connected to the base plate, and a second threaded sleeve is fitted on the surface of the first threaded rod. The first threaded rod and the second threaded sleeve are threadedly connected. Left support arms are movably installed on both sides of the second threaded sleeve. Movable shafts are movably installed on the side of the left support arm away from the second threaded sleeve. The left support arms are movably connected to the lifting plate through the movable shafts.

[0012] Optionally, a support shaft is symmetrically and movably installed on the side of the base plate away from the power motor. A right support arm is movably fitted on the surface of each support shaft. A rotating shaft is movably installed at the intersection of the right support arm and the left support arm. The rotating shaft passes through the left support arm and the right support arm and extends to their outside. First rollers are movably installed on both sides of the left support arm.

[0013] Optionally, the first rollers are all slidably connected to the base plate, and the outside of the lifting plate is provided with an extension shaft. The extension shaft extends through the right support arm and is movably connected to it. Second rollers are movably fitted on both sides of the extension shaft, and the second rollers are all slidably connected to the lifting plate.

[0014] Optionally, a battery is installed inside the hollow shaft, a wireless transmission module is installed inside the hollow shaft near the battery, a control panel is installed inside the hollow shaft near the wireless transmission module, an electric push rod is installed inside the hollow shaft near the control panel, and a sliding sleeve is fitted on the outside of the hollow shaft.

[0015] Optionally, the output end of the electric push rod is movably connected to the sliding sleeve, and three sets of first connecting arms are movably mounted on the surface of the sliding sleeve. A second shaft is movably mounted on the side of each first connecting arm away from the sliding sleeve, and three sets of first shafts with equal spacing are symmetrically and movably mounted on the outside of the hollow shaft.

[0016] Optionally, the surface of the first shaft is fitted with a second connecting arm, and the hollow shaft is provided with three sets of connecting arms at equal intervals. Electric rollers are movably installed on both sides of the connecting arms, and a third shaft is movably installed on the side of the second connecting arm away from the first shaft.

[0017] Optionally, all second connecting arms are movably connected to the connecting arm via a third axis, and all first connecting arms are movably connected to a group of second connecting arms via a second axis. The output end of the control panel is electrically connected to the input end of the servo motor, stepper motor, power motor, wireless transmission module, electric actuator, and battery.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the wire feeding device not only realizes the convenient reciprocating movement of the wire feeding device for conveying and feeding, avoiding the situation of tangling and knotting, and facilitating the convenient adjustment of height for wire feeding, but also facilitates convenient wire feeding inside the pipe, thus improving the wire feeding effect of the wire feeding device.

[0019] A servo motor drives a rotating shaft to rotate, which in turn drives a cable drum to rotate. The cable drum then drives the cable on its surface to rotate. The cable passes through a first threaded sleeve on the surface of a rolling wheel and connects to the outside. A stepper motor drives a reciprocating threaded rod to rotate, which in turn drives the first threaded sleeve to move back and forth. The first threaded sleeve then drives the rolling wheel and the cable on its surface to move back and forth, thus avoiding tangling and knotting. This enables the cable feeding device to move back and forth conveniently for conveying and feeding the cable, and improves the efficiency of the cable feeding device's reciprocating rotation for conveying and feeding the cable.

[0020] The power motor drives the first threaded rod to rotate, which in turn moves the second threaded sleeve. The second threaded sleeve then moves the left support arm, which in turn moves the two sets of first rollers inside the base plate. Under the limiting support of the rotating shaft, the left support arm drives the rotating shaft to rotate. Under the movable support of the movable shaft and the limiting of the support shaft, the left support arm drives the right support arm to rotate around the support shaft. Under the movable support of the extension shaft, the right support arm drives the two sets of second rollers to slide inside the lifting plate, causing the lifting plate to move upward. The lifting plate then moves the support frame, cable drum, and cable upward, enabling convenient height adjustment for the cable feeding device, increasing the feeding range, and improving the convenience of adjusting the height for cable feeding.

[0021] An electric push rod drives a sliding sleeve to move, which in turn moves three sets of first connecting arms. Under the limiting support of the first shaft, the first connecting arm drives the second connecting arm to rotate around the first shaft via the second shaft. The second connecting arm drives the connecting arm to expand outward via the third shaft, causing multiple sets of electric rollers to contact the inner wall of the pipe. Opening the multiple sets of electric rollers allows them to rotate and run along the inner wall of the pipe, thus achieving the purpose of laying the line. This enables the line laying device to conveniently lay lines inside the pipe, reducing manual labor intensity and improving the line laying efficiency. Attached Figure Description
