Description

Technical Field

[0001] The invention relates to the technical field of measuring devices, in particular to a field data laying-out measuring device for engineering cost. Background Art

[0002] Project cost is a work process that uses knowledge and skills from management, economics, and engineering technology to predict, plan, control, calculate, analyze, and evaluate project costs. During on-site construction, it is necessary to use a layout measurement device to carry out layout measurement. Layout measurement refers to determining the plane position of building structures on the ground according to the requirements of the design drawings.

[0003] The existing wire-paying and measuring device has a relatively simple structure and has certain shortcomings in use. On the one hand, the take-up wheel is not provided with a fixing mechanism, and it is easy to rotate by itself due to external force during use. In this way, when the line is wound onto the take-up wheel, due to the lack of a fixing mechanism, the line wound on the take-up wheel is easy to become loose and randomly entangled inside the wire-paying and measuring device, affecting the normal use of the device. In the process of paying out the line, when pulling the line, the take-up wheel is easy to rotate too fast due to inertia, resulting in a too fast pay-out speed that is difficult to control, affecting the measurement operation. On the other hand, when the line is wound, the line is in a relaxed state, so that the line wound onto the take-up wheel is overall loose and not compact enough, which may lead to the phenomenon of random winding and unsmooth winding. In the process of paying out the line, more impurities will adhere to the line, and the line cannot be wound after the impurities are removed, so that the impurities enter the interior of the device, causing an adverse effect on the device.

In addition, the clamping roller 82 tightly clamps the line end at this time, and the matching abutment 67 at this time abuts against the side convex extension portion 84, thereby preventing the two clamping rollers 82 from moving away from each other. Under the action of the clamping roller 82, the line end can be prevented from retracting into the interior of the measuring device housing 1. When the line is being paid out, the threaded adjustment column 43 is rotated to drive the driving connecting plate 4 to move downward, so that the plug-in fixing column 48 withdraws from the fixed socket 32, and at the same time, under the action of the V-shaped groove 45, the two limiting bearing plates 5 are driven to move toward each other, so that the rubber pad 52 fits in the first On a support shaft 31, at the same time, under the action of the first matching hinge rod 49, the first movable connecting frame 6 will be pushed to move in the direction of the supporting convex strip 25, and then under the action of the third matching hinge rod 63, the driving frame 64 will be pushed to move in the direction away from the wire-releasing hole 12, so that the matching block 67 will be separated from the side convex extension portion 84, and the matching top column 68 will move along the first inclined surface portion 87 to the flat surface portion 88, and then under the action of the matching top column 68, the two clamping rollers 82 will move away from each other and no longer clamp the wire body, so that the wire head can be pulled for wire release. At this time, the clamping roller 82 will not hinder the wire body, ensuring the smooth progress of wire release. In addition, the downward movement of the driving connecting plate 4 will be under the action of the second matching hinge rod 50 The movable bar 7 is driven downward to move in the direction away from the mounting hole 21, and then the two mounting frames 9 are driven to move towards each other under the action of the V-shaped frame 73. In the process of releasing the line, the rubber pad 52 is in contact with the first support shaft 31, which makes the friction larger. In this way, the rotation of the take-up wheel 3 is restricted to a certain extent, and the line release will not be difficult to control due to excessive inertia rotation, which affects the smooth progress of the line release operation. When it is necessary to reel in the line, the threaded adjustment column 43 is continuously rotated downward to drive the driving connecting plate 4 to move further downward. Under the action of the V-shaped groove 45, the two limiting bearing plates 5 are driven to move in opposite directions, so that the rubber pad 52 is separated from the first support shaft 31. At the same time, with the movement of the mounting frame 9, The sponge wiping strip 95 will contact the wire body, and the cooperating top column 68 will pass over the second inclined portion 89 and separate from the top connecting plate 86, so that the take-up wheel 3 can be rotated to take up the wire. Under the action of the sponge wiping strip 95, impurities on the wire body can be cleaned up to prevent them from entering the interior of the device. At the same time, the clamping roller 82 always has a certain clamping force on the wire body under the action of the connecting spring 90, and the clamping roller 82 can move to ensure that the wire body can be smoothly wound up. In this way, under the action of the clamping force, the wire body between the clamping roller 82 and the take-up wheel 3 is in a certain tension state, which is convenient for compact winding on the take-up wheel 3, ensuring the winding quality. After the winding is completed, the threaded adjustment column 43 is rotated in the opposite direction to drive the driving connecting plate 4 to reset.
