Description

Technical Field

[0001] The utility model relates to the technical field of electric power civil engineering, and particularly relates to a civil engineering survey and setting-out device. Background Technique

[0002] During the construction of electric power civil engineering projects, in order to accurately transform the design on the construction drawings into on-site positioning and ensure that buildings, infrastructure, etc. are accurately constructed according to the design requirements, workers usually use a civil engineering survey and setting-out device to set out the survey line to ensure the construction accuracy. The existing civil engineering survey and setting-out devices usually consist of a fixed frame, a driving mechanism, and a wire-releasing roller.

[0003] For example: The utility model with the application number CN202323035098.8 discloses a civil engineering survey and setting-out device, which specifically includes a base; a movable groove is opened at the bottom of the base, and a support bar is arranged in the movable groove; a connecting seat is fixed on the top of the base, and a first connecting plate and a second connecting plate are symmetrically fixed on the top of the connecting seat. A movable rod is movably connected between the first connecting plate and the second connecting plate; a set of survey lines is installed on the outer wall of the movable rod. By using a crank to drive the set of survey lines to rotate through the movable rod, the survey lines on the set of survey lines can be wound up, which is relatively simple and convenient, thereby improving the overall work efficiency.

[0004] However, for the current traditional civil engineering survey and setting-out devices, in order to ensure that the wire-releasing roller does not loosen during the wire-releasing process, workers usually use bolts to fix the wire-releasing roller. Although this fixing method is stable, when the wire roller needs to be replaced or disassembled, workers need to loosen the bolts fixing the wire-releasing roller one by one, and the operation is relatively cumbersome, resulting in a large labor intensity for the workers. Content of the Utility Model

[0005] In view of this, the utility model provides a civil engineering survey and setting-out device, which has a sliding sleeve that can facilitate workers to quickly replace and disassemble the wire-releasing roller. By pulling the sliding sleeve, the sliding sleeve slides along the first sleeve. During the sliding process of the first sleeve, the fixed spring will be compressed. As the first sleeve slides, a notch will appear in the first sleeve, which is convenient for subsequent replacement of the wire-releasing roller. In the initial state, the blocking slide plate locks the locking block, and at this time, the spring telescopic rod cannot be telescoped. During the movement of the sliding sleeve, the control slide is controlled to move, so that the control slide is inserted into the control chute and squeezes the control chute, causing the blocking slide plate to slide on the fixed ring and stretch the return spring. As the blocking slide plate slides, the locking groove will be exposed. At this time, pulling the first sleeve can make the locking block slide along the locking groove, enabling the spring telescopic rod to be telescoped, which is convenient for pulling out the wire-releasing roller for replacement.

[0006] The utility model provides a civil engineering surveying and setting-out device, which specifically includes: a fixed bottom plate; two support columns are symmetrically and fixedly connected to the top surface of the fixed bottom plate; a telescopic column is slidably connected in each of the two support columns; a second sleeve is rotatably connected to the upper part of the left telescopic column; a wire-releasing roller is inserted into the second sleeve; a transmission rotating shaft is rotatably connected to the upper part of the right telescopic column; a spring telescopic rod is fixedly connected to the inner side of the transmission rotating shaft; a first sleeve is fixedly connected to the end of the output shaft of the spring telescopic rod; the first sleeve is aligned with the second sleeve; the end of the wire-releasing roller is inserted into the first sleeve.

[0009] Optionally, a sliding sleeve is slidably connected to the outside of the first sleeve; multiple groups of fixing springs are fixedly connected to the outside of the sliding sleeve; the ends of the multiple groups of fixing springs are all fixedly connected to the outside of the first sleeve.

[0010] Optionally, a control sliding frame is fixedly connected to the outside of the sliding sleeve; a fixing ring is fixedly connected to the outside of the spring telescopic rod; a blocking sliding plate is slidably connected to the outside of the fixing ring; a control sliding groove is formed in the outside of the blocking sliding plate; two reset springs are symmetrically and fixedly connected to the outside of the blocking sliding plate; the ends of the two reset springs are both fixedly connected to the outside of the fixing ring; the control sliding frame is aligned with the control sliding groove; a locking groove is formed in the outside of the fixing ring; a locking block is fixedly connected to the outside of the first sleeve; the locking block is aligned with the locking groove.

[0012] Beneficial effects

[0034] Specific usage method and function of this embodiment: In the present application, the rotating shaft of the wire pay-off roller 121 is a spline shaft, and the inner walls of the first sleeve 116 and the second sleeve 120 are both spline grooves. The support column 101 is supported by the setting of the fixed base plate 1. By pulling the limit insertion rod 105, the limit insertion rod 105 moves and stretches the connecting spring 104. As the limit insertion rod 105 moves, it will disengage from the limit slot 103. At this time, the staff can slide the telescopic column 102 in the support column 101 to facilitate the adjustment of the height of the wire pay-off roller 121, thereby relatively extending the length of the measuring rope on the wire pay-off roller 121. After the height of the telescopic column 102 is adjusted, the staff releases the limit insertion rod 105, and the limit insertion rod 105 is reset and inserted into the aligned limit slot 103 with the rebound of the connecting spring 104 to fix the position of the telescopic column 102. By starting the driving motor 107, the driving motor 107 drives the first belt pulley 108 to rotate. During the rotation of the first belt pulley 108, the second belt pulley 110 is driven to rotate through the transmission belt. During the rotation of the second belt pulley 110, the transmission rotating shaft 109 is driven to rotate. During the rotation of the transmission rotating shaft 109, the first sleeve 116 is driven to rotate through the spring telescopic rod 111. During the rotation of the first sleeve 116, the wire pay-off roller 121 and the second sleeve 120 are driven to rotate to pay off and wind up the measuring wire. When replacing the wire pay-off roller 121, the staff pulls the sliding sleeve 117, and the sliding sleeve 117 slides along the first sleeve 116. During the sliding of the first sleeve 116, the fixed spring 118 is compressed. As the first sleeve 116 slides, a notch appears in the first sleeve 116, which is convenient for subsequent replacement of the wire pay-off roller 121. In the initial state, the blocking slide plate 113 locks the locking block 126. At this time, the spring telescopic rod 111 cannot be telescoped. During the movement of the sliding sleeve 117, the control carriage 119 is controlled to move, and the control carriage 119 is inserted into the control chute 115 to squeeze the control chute 115, so that the blocking slide plate 113 slides on the fixed ring 112 and stretches the return spring 114. As the blocking slide plate 113 slides, the locking groove 127 is exposed. At this time, by pulling the first sleeve 116, the locking block 126 can slide along the locking groove 127, and the spring telescopic rod 111 can be telescoped, which is convenient for pulling out the wire pay-off roller 121 for replacement.
