Technical Field
[0001] The utility model relates to the technical field of line-laying devices, in particular to a construction foundation positioning and line-laying device. Background Art
[0002] A construction foundation positioning and setting-out device is a combination of measuring and positioning tools used at construction sites. Its main function is to accurately set out and position the construction site according to the positioning elevations and positioning coordinates on the design drawings. A construction foundation positioning and setting-out device usually includes the following main parts: measuring instruments: such as theodolites, levels, rangefinders, total stations, etc., which are used for precise measurement and positioning; setting-out tools: such as nails, ropes, cement markers, etc., which are used for actual setting out and marking at the construction site; auxiliary equipment: such as tripods, laser transmitters, receiving targets, etc., which are used to support the measuring instruments and ensure the accuracy of the measurements.
[0003] The common positioning and laying-out process is to first determine the point position through a measuring instrument, then set markers such as iron nails at the designated point position, and then actually lay out the line by pulling a rope between the markers. In order to ensure the laying-out effect, the rope usually needs to be tightened in a tensioned state when pulling the rope, and then the two ends are fixed to the iron nails on both sides. The operation is cumbersome and time-consuming. In particular, when the above method needs to adjust the point position, it is often necessary to cut the rope first and then tie a new rope again. The operation is inconvenient and easy to waste the rope. Therefore, in response to the above problems, a construction foundation positioning and laying-out device is proposed. Utility Model Content
[0004] The present invention provides a device for positioning and tensioning a foundation, wherein the device is configured to fix the foundation by inserting a rod into the soil, and the wire tensioning mechanism is configured to tension the foundation. Specifically, the winding wheel is rotated to drive the winding wheel to rotate to reel in the end of the positioning wire, thereby achieving the tensioning effect. This tensioning method is simple, efficient and loose, which means that when adjusting the point, the winding wheel can be rotated in the opposite direction to lose the restraining effect on the positioning wire, so that the positioning wire can slide freely in the winding wheel, thereby facilitating the adjustment of the point. After the adjustment is completed, the winding wheel can be rotated to tension the positioning wire, without the need to re-tie the positioning wire and causing no waste of the positioning wire. This solves the technical problems in the prior art that the operation of fixing and tensioning the wire rope is cumbersome and time-consuming, and when the point needs to be adjusted, the wire rope often needs to be cut first and then a new wire rope needs to be tied again, resulting in inconvenient operation and easy waste of wire rope.
[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:
[0006] A construction foundation positioning and laying-out device comprises a base, a lower end face of which is fixedly provided with a centrally arranged insertion rod, a wire tightening mechanism, a positioning wire movably passed through the base, the wire tightening mechanism rewinds the positioning wire by rotation, and a locking mechanism for limiting the rotation of the wire tightening mechanism, wherein the wire tightening mechanism comprises an articulated seat, a rotating winding wheel is mounted on the articulated seat, a through hole is provided in the middle of the winding wheel for the positioning wire to pass through, and a tightening hand wheel is fixedly provided on one side of the winding wheel.
[0007] Through the above-mentioned structural form, the layout point is fixed by inserting the rod into the soil, and the positioning line is tensioned by the line tightening mechanism. Specifically, the tightening handwheel drives the winding wheel to rotate to reel in the end of the positioning line, thereby achieving the tensioning effect. This tensioning method is simple, efficient and loose, which means that when adjusting the point, the winding wheel can be rotated in the opposite direction to lose its restraining effect on the positioning line, so that the positioning line can slide freely in the winding wheel, thereby facilitating the adjustment of the point. After the adjustment is completed, the winding wheel can be rotated to tension the positioning line. There is no need to re-tie the positioning line, and no waste of the positioning line will be caused.

[0009] Through the above-mentioned structural form, the clutch of the dynamic clamping wheel and the static clamping wheel can be used to limit and release the restriction on the rotation of the winding wheel. That is, after the winding wheel is rotated to tighten the positioning line, the engagement of the dynamic clamping wheel and the static clamping wheel can prevent the winding wheel from rotating and ensure the continuity of tension. The separation of the dynamic clamping wheel and the static clamping wheel allows the winding wheel to rotate freely, and then the rotation contact of the Forbidden City can be used to constrain the winding wheel, which is convenient for point adjustment.
[0010] In a possible implementation, a plurality of convex teeth arranged in a circumferential array are fixedly provided on the opposite end surfaces of the movable clamping wheel and the static clamping wheel, and clamping grooves are formed between the convex teeth, and the convex teeth match the clamping grooves in size.
[0011] The above-mentioned structural form can ensure the tightness of the fit between the dynamic clamping wheel and the static clamping wheel, so that the rotation of the winding wheel can be completely restricted when the two are in fit.
[0012] In a possible implementation, the guide rod outer sleeve is provided with a compression spring, and both ends of the compression spring are fixedly connected to the sliding sheet and the connecting ear respectively.
[0013] Through the above-mentioned structural form, it can be ensured that when there is no external force, the dynamic clamping wheel and the static clamping wheel can always maintain a tight fit under the tension of the compression spring, thereby continuously limiting the rotation of the winding wheel and ensuring that the positioning line is always in a tensioned state.
[0014] In a possible implementation, when the movable clamping wheel and the static clamping wheel are in contact with each other, the compression spring is still in a tensioned state.
[0015] The above-mentioned structural form can ensure that the compression tension spring can provide tension in the initial state to force the dynamic clamping wheel and the static clamping wheel to fit tightly.
[0016] In a possible implementation, an outwardly protruding anti-separation end piece is fixedly provided on the end of the guide rod, and a centrally arranged pull tab is fixedly provided on the sliding piece.
[0017] With the above-mentioned structural form, the anti-separation end piece can prevent the sliding piece from sliding off the guide rod, while the pull piece can facilitate the user to pull the sliding piece.
[0018] In one possible implementation, an auxiliary anchoring mechanism is provided on the side of the base, and the auxiliary anchoring mechanism includes a mounting side plate, and both sides of the outer end surface of the mounting side plate are rotatably connected to a slide cylinder, and an anchor rod with a pressing plate on the top is slidably provided in the slide cylinder.
[0019] Through the above-mentioned structural form, the anchor rod can be inserted into the ground at an angle, thereby improving the pull-out resistance and anti-tilting ability of the insertion rod, avoiding pulling out or pulling off when tensioning the positioning line, thereby affecting the accuracy of the line release.
[0020] In a possible implementation, a winding groove is provided in the middle of the winding wheel, the winding wheel is in an I-shape as a whole, and guide slopes sloping toward the winding groove are provided on both sides thereof.
[0021] Through the above-mentioned structural form, the opening of the winding groove can provide the necessary structural basis for the orderly winding of the positioning line. At the same time, the guide slope can directly guide the positioning line into the winding groove when winding it, thereby facilitating the smooth progress of the winding work.
[0022] In summary, the present invention has the following beneficial technical effects:
[0023] The stakeout point is fixed by inserting a rod into the soil, and the positioning line is tensioned by a line tightening mechanism. Specifically, tightening the handwheel drives the winding wheel to rotate and wind up the end of the positioning line, thereby achieving tensioning. This tensioning method is simple, efficient and loose. As a result, when adjusting the point, the winding wheel can be rotated in the opposite direction to make it lose its restraining effect on the positioning line, so that the positioning line can slide freely in the winding wheel, thereby facilitating the adjustment of the point. After the adjustment is completed, the winding wheel can be rotated to tension the positioning line. There is no need to re-tie the positioning line, and no waste of the positioning line will be caused. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:
[0031] like Figure 1 - Figure 2As shown, the present embodiment provides a construction foundation positioning and laying-out device, comprising a base 1, a centrally arranged insertion rod 2 fixedly provided on the lower end face thereof, a line tightening mechanism 3, wherein a positioning line 4 is movably passed through the line tightening mechanism 3, the line tightening mechanism 3 rewinds the positioning line 4 by rotation, and a locking mechanism 5 is used to limit the rotation of the line tightening mechanism 3, wherein the line tightening mechanism 3 comprises an articulated seat 31, a rotating winding wheel 32 is mounted on the articulated seat 31, a through hole is provided in the middle of the winding wheel 32 for the positioning line 4 to pass through, and a tightening hand wheel 33 is fixedly provided on one side of the winding wheel 32, through the above-mentioned structural form, the positioning is realized by inserting the insertion rod 2 into the soil. The layout point is fixed, and the positioning line 4 is tensioned by the line tightening mechanism 3. Specifically, the hand wheel 33 is tightened to drive the winding wheel 32 to rotate and wind up the end of the positioning line 4, so that the tensioning effect can be achieved. This tensioning method is simple, efficient and loose. As a result, when adjusting the point, the winding wheel 32 can be rotated in the opposite direction to make it lose its restraining effect on the positioning line 4, so that the positioning line 4 can slide freely in the winding wheel 32, thereby facilitating the adjustment of the point. After the adjustment is completed, the winding wheel 32 can be rotated to tension the positioning line 4. There is no need to re-tie the positioning line 4, and no waste of the positioning line 4 will be caused.
[0032] like Figure 3 As shown, the locking mechanism 5 includes a dynamic card wheel 51 and a static card wheel 52. At the same time, the hinge seat 31 is fixedly connected to a guide rod 53 through a connecting ear 531, and a sliding plate 54 is slidably provided on the guide rod 53. Among them, the dynamic card wheel 51 is fixedly connected to the other side of the winding wheel 32, and the static card wheel 52 is fixedly installed on the sliding plate 54. Through the above structural form, the dynamic card wheel 51 and the static card wheel 52 can be engaged with each other to limit and release the restriction on the rotation of the winding wheel 32, that is, after the winding wheel 32 is rotated to tension the positioning line 4, the engagement of the dynamic card wheel 51 and the static card wheel 52 can prevent the winding wheel 32 from rotating and ensure the continuity of the tension. The separation of the dynamic card wheel 51 and the static card wheel 52 allows the winding wheel 32 to rotate freely, and then can be restrained by the rotation contact of the Forbidden City on the winding wheel 32, which is convenient for point adjustment.
[0033] Among them, a number of convex teeth 501 arranged in a circular array are fixedly provided on the opposite end faces of the dynamic clamping wheel 51 and the static clamping wheel 52, and a clamping groove 502 is formed between the convex teeth 501, and the convex teeth 501 are consistent in size with the clamping groove 502. Through the above-mentioned structural form, the tightness of the fit between the dynamic clamping wheel 51 and the static clamping wheel 52 can be ensured, so that when the two are in fit, the rotation of the winding wheel 32 can be completely restricted.
[0034] In addition, a compression spring 55 is provided on the outer sleeve of the guide rod 53, and the two ends of the compression spring 55 are fixedly connected to the sliding plate 54 and the connecting ear 531 respectively. Through the above-mentioned structural form, it can be ensured that when there is no external force, the dynamic clamping wheel 51 and the static clamping wheel 52 can always maintain a tightly fitted state under the tension of the compression spring 55, and then continue to play a role in limiting the rotation of the winding wheel 32, ensuring that the positioning line 4 is always in a tensioned state, and when the dynamic clamping wheel 51 and the static clamping wheel 52 are in contact with each other, the compression spring 55 is still in a tensioned state. This structural form can ensure that the compression spring 55 can provide tension in the initial state to force the dynamic clamping wheel 51 and the static clamping wheel 52 to fit tightly.
[0035] like Figure 3 As shown, an outwardly protruding anti-separation end piece is fixedly provided at the end of the guide rod 53, and a centrally arranged pull tab 56 is fixedly provided on the sliding sheet 54. Through the above-mentioned structural form, the anti-separation end piece can prevent the sliding sheet 54 from sliding off the guide rod 53, while the pull tab 56 can facilitate the user to pull the sliding sheet 54.
[0036] like Figure 4 As shown, an auxiliary anchoring mechanism 6 is provided on the side of the base 1, and the auxiliary anchoring mechanism 6 includes a mounting side plate 61. Both sides of the outer end surface of the mounting side plate 61 are rotatably connected to a slide 62. An anchor rod 63 with a pressing piece 64 on the top is slidably provided in the slide 62. Through the above-mentioned structural form, the anchor rod 63 can be inserted into the ground at an angle to improve the pull-out and anti-tilting capabilities of the insertion rod 2, thereby avoiding pulling out or deflecting the positioning line 4 when tensioning it, thereby affecting the accuracy of the line release.
[0037] like Figure 2 As shown, a winding groove is provided in the middle of the winding wheel 32. The winding wheel 32 is in an I-shape as a whole, and guide slopes 321 sloping toward the winding groove are provided on both sides thereof. Through the above-mentioned structural form, the opening of the winding groove can provide the necessary structural basis for the orderly winding of the positioning line 4. At the same time, the guide slope 321 can directly guide the positioning line 4 into the winding groove when winding it, so as to facilitate the smooth progress of the winding work.
[0038] The use principle and use process of this utility model:
[0039] The layout point is fixed by inserting the rod 2 into the soil, and the positioning line 4 is tensioned by the line tightening mechanism 3. Specifically, tightening the hand wheel 33 drives the winding wheel 32 to rotate and wind up the end of the positioning line 4, which can achieve the tensioning effect. This tensioning method is simple, efficient and loose. As a result, when adjusting the point, the winding wheel 32 can be rotated in the opposite direction to make it lose its restraining effect on the positioning line 4, so that the positioning line 4 can slide freely in the winding wheel 32, thereby facilitating the adjustment of the point. After the adjustment is completed, the winding wheel 32 can be rotated to tension the positioning line 4. There is no need to re-tie the positioning line 4, and no waste of the positioning line 4 will be caused.
[0040] To cooperate with the above technical solution, a locking mechanism 5 is provided to limit the rotation of the wire tightening mechanism 3, which can limit and release the rotation of the winding wheel 32 by the clutch of the dynamic clamping wheel 51 and the static clamping wheel 52. That is, after the winding wheel 32 is rotated to tension the positioning line 4, the engagement of the dynamic clamping wheel 51 and the static clamping wheel 52 can prevent the winding wheel 32 from rotating, thereby ensuring the continuity of the tension. The separation of the dynamic clamping wheel 51 and the static clamping wheel 52 allows the winding wheel 32 to rotate freely, and then the rotation contact of the Forbidden City can be used to restrain the winding wheel 32, which is convenient for the adjustment of the point position.
[0041] At the same time, in the locking mechanism 5, the dynamic clamping wheel 51 and the static clamping wheel 52 can always maintain a tightly fitted state under the tension of the compression tension spring 55, thereby continuously limiting the rotation of the winding wheel 32, ensuring that the positioning line 4 is always in a tensioned state, and when the dynamic clamping wheel 51 and the static clamping wheel 52 are fitted with each other, the compression tension spring 55 is still in a stretched and taut state. This structural form can ensure that the compression tension spring 55 can provide tension in the initial state to force the dynamic clamping wheel 51 and the static clamping wheel 52 to fit tightly.
[0042] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
