Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a civil engineering measuring and setting-out device. Background Art

[0002] Civil engineering generally refers to civil engineering projects. Civil engineering projects refer to the planning, construction and maintenance of all infrastructure related to water, soil and culture. In reality, general civil engineering projects include houses, roads, water services, canal services, flood control projects and transportation, etc. Before the civil engineering project is carried out, it is generally necessary to use a line-laying device to measure the construction site. When encountering muddy and watery ground, the rope will be sticky with mud or clay after the line-laying measurement. Since the existing line-laying device lacks a cleaning mechanism, the rope will be sticky with mud and dirt, which will increase its weight. When the line is repeatedly laid out, it is more laborious to retract and release the rope. In view of the above problems, a civil engineering measurement and laying-out device is proposed.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0018] Below, the civil engineering surveying and setting-out device according to the embodiment of the utility model is described with reference to the accompanying drawings. Figures 1 to 5As shown, the civil engineering surveying and laying-out device comprises an outer frame 1 and a roller 2 hinged in the outer frame 1, anchor nails 101 are provided at the four corners of the bottom of the outer frame 1, a slot 105 is provided on one side wall of the outer frame 1, a handle 102 is provided on the other side wall of the outer frame 1, a brush roller 8 is provided in the slot 105, and two guide rods 103 are symmetrically provided in the outer frame 1, and a moving platform 7 is provided on the two guide rods 103.

[0019] Preferably, there are two brush rollers 8 which are symmetrically arranged. The brush rollers 8 are rotatably installed in the grooves 105 through bearings. A hook 104 is also provided on the side wall of the outer frame 1. A plug rod 6 is hung on the hook 104. A rope is wrapped around the roller 2. The movable end of the rope passes through the brush roller 8 and is sleeved on the plug rod 6. The rope fits tightly against the two brush rollers 8.

[0020] Preferably, a reciprocating screw 5 is provided between the two guide rods 103 , and the reciprocating screw 5 is rotatably installed in the outer frame 1 through a bearing, a second pulley 501 is provided on the top of the reciprocating screw 5 , and a turntable 3 is provided on the top of the roller 2 .

[0021] Preferably, a first pulley 302 is provided at the connection between the turntable 3 and the roller 2, a handle 301 is provided on the top of the turntable 3, and a transmission belt 4 is provided between the first pulley 302 and the second pulley 501 to connect.

[0022] In a specific embodiment: when winding the line, the staff pulls the handle 301 to drive the turntable 3 to rotate, and the turntable 3 drives the roller 2 to rotate, so as to wind the rope on the roller 2. When the rope moves, it will drive the two brush rollers 8 that are tightly fitted with it to rotate, and the brush rollers 8 are used to scrape off the dirt on the rope, so as to avoid the increase of weight of the rope after being stuck with dirt, and winding and releasing the rope is more labor-saving and convenient to use.

[0023] Preferably, guide holes 701 are symmetrically provided on both sides of the movable platform 7 , a connecting hole 703 is provided in the middle of the movable platform 7 , a through hole 702 is provided between the connecting hole 703 and the guide hole 701 on one side, and the guide hole 701 is movably connected to the guide rod 103 .

[0024] Preferably, a rope is passed through the through hole 702 , and the connecting hole 703 is movably connected to the reciprocating screw 5 . When the reciprocating screw 5 rotates, the moving platform 7 will perform reciprocating lifting motion along the reciprocating screw 5 .

[0025] In a specific embodiment: when in use, by rotating the turntable 3, the roller 2 and the first pulley 302 are driven to rotate, the first pulley 302 drives the second pulley 501 to rotate via the transmission belt 4, and the second pulley 501 drives the reciprocating screw 5 to rotate. After the reciprocating screw 5 rotates, the moving platform 7 will perform reciprocating lifting and lowering motion along the reciprocating screw 5. Since a rope is passed through the through hole 702 on the moving platform 7, the rope will be evenly wound around the roller 2 when winding, and the winding effect is better.

[0026] Working principle: when in use, the device is fixed by the anchor nail 101, and then the staff removes the plug rod 6 from the hook 104 and places it at the target position for measurement. After the measurement is completed, the staff pulls the handle 301 to drive the turntable 3 to rotate, and the turntable 3 drives the roller 2 to rotate, so as to reel in the rope on the roller 2. When the rope moves, it will drive the two brush rollers 8 that are closely fitted with it to rotate, and the brush rollers 8 are used to scrape off the dirt on the rope to avoid the rope from being sticky with dirt and increasing its weight. The rope is more labor-saving and easy to use. At the same time, when the turntable 3 rotates, it will drive the first pulley 302 to rotate, and the first pulley 302 drives the second pulley 501 to rotate via the transmission belt 4, and the second pulley 501 drives the reciprocating screw 5 to rotate. After the reciprocating screw 5 rotates, the moving platform 7 will perform reciprocating lifting and lowering motion along the reciprocating screw 5. Since the through hole 702 on the moving platform 7 is provided with a rope, the rope will be evenly wound around the roller 2 when it is reeled in, and the winding effect is better.
