Description

Technical Field

[0001] The utility model relates to the technical field of lofting rods, in particular to a lofting rod which can be quickly stored and is used for bridge engineering construction. Background Art

[0002] The stakeout rod is one of the tools used for stakeout in bridge engineering. Stakeout refers to the corresponding marking and arrangement work on site according to the dimensions and requirements on the design drawings. The stakeout rod is usually a long rod with scales or lengths marked on it, which is used to measure and mark the position and dimensions of various parts of the bridge. During the bridge construction process, the stakeout rod can help construction workers accurately locate and arrange components to ensure construction quality and accuracy. Most of the existing stakeout rods are integrated settings. Since the construction site often has limited space and many equipment, the stakeout rod may cause potential tripping or collision risks on the construction site, affecting the safety of construction; therefore, we propose a stakeout rod for bridge construction that can be quickly retracted to solve the above-mentioned problems. Utility Model Content

[0003] In order to overcome the problem that most existing stakeout rods are integrated, since construction sites often have limited space and a large number of equipment, stakeout rods may cause potential tripping or collision risks at the construction site, affecting the safety of construction.

[0004] The technical solution of the utility model is: a quickly foldable stakeout rod for bridge engineering construction, comprising a storage module, a first telescopic module and a second telescopic module; the storage module is internally sleeved with the first telescopic module for moving in and out to facilitate adjustment of the length of the stakeout rod according to measurement requirements, and the first telescopic module is internally sleeved with the second telescopic module for moving in and out to facilitate adjustment of the length of the stakeout rod and measurement.

[0005] Preferably, when the length is adjusted, hold the handle and measure with the laser pointer. During this process, the groove can increase friction to prevent the layout rod from slipping during measurement. After the measurement is completed, remove the laser pointer, the first pin and the second pin in turn, then move the telescopic sleeve and the telescopic rod back into the sleeve, and then manually rotate the rotating cover. The rotating cover is rotatably connected to the sleeve through the connecting shaft, so that the rotating cover and the sleeve are closed, and then the elastic connecting belt passes through the circular hole through the positioning button and is positioned and connected to the sleeve. Finally, by lifting the handle, the sleeve is driven to move to the next position to be measured to avoid potential tripping or collision risks at the construction site.

[0006] Preferably, the storage module includes a grip, a handle, a sleeve, a positioning button, a first pin, a connecting shaft, a rotating cover and an elastic connecting belt. The grip is installed at one end of the sleeve, and multiple groups of grooves for increasing friction are arranged around the outside of the handle. A handle is installed at one end of the outside of the sleeve near the grip. When the length is adjusted, measurement is performed by holding the handle. During this process, the groove can increase friction to prevent the layout rod from slipping during measurement.

[0007] Preferably, a connecting shaft is installed at the edge of one end of the sleeve away from the handle, and a rotating cover is provided at the end of the sleeve away from the handle. The rotating cover is rotatably connected to the sleeve through the connecting shaft, and then the rotating cover is manually rotated and the rotating cover is rotatably connected to the sleeve through the connecting shaft, thereby closing the rotating cover and the sleeve.

[0008] Preferably, a positioning button is installed on the side of the sleeve away from the connecting shaft, and an elastic connecting belt is installed on the side of the rotating cover away from the connecting shaft. A circular hole for the positioning button to pass through is opened at the end of the elastic connecting belt away from the rotating cover. The elastic connecting belt passes through the circular hole through the positioning button to be positioned and connected to the sleeve. Then the elastic connecting belt passes through the circular hole through the positioning button to be positioned and connected to the sleeve. Finally, the handle is lifted to drive the sleeve to move to the next position to be measured, thereby avoiding potential tripping or collision risks at the construction site.

[0009] Preferably, a first plug hole for the first pin to pass through is provided above one end of the sleeve close to the connecting shaft, and the first plug pin is connected to the sleeve positioning tube through the first plug hole. After the measurement is completed, the laser indicator, the first plug pin and the second plug pin are removed in sequence, and then the telescopic sleeve and the telescopic rod are moved back into the sleeve.

[0010] Preferably, the first telescopic module includes a telescopic sleeve and a second pin. The telescopic sleeve is laterally provided with a plurality of positioning holes for the first pin to pass through. An outer side of the telescopic sleeve is provided with a second plugging hole for the second plugging hole for the second plugging hole. The second plugging pin is positioned and connected to the telescopic sleeve through the second plugging hole. Through manual adjustment, the telescopic sleeve is moved out along the sleeve. After moving to a suitable position, the first plugging pin passes through the first plugging hole and is positioned and connected to the telescopic sleeve through the positioning hole.

[0011] Preferably, the second telescopic module includes a telescopic rod and a laser pointer. The telescopic rod is laterally provided with a plurality of connecting holes for the second pin to pass through. An end of the telescopic rod away from the telescopic sleeve is provided with a mounting circular groove for installing the laser pointer. The laser pointer is fixedly connected to the telescopic rod through the mounting circular groove. Then the telescopic rod is moved out along the telescopic sleeve. After moving to a suitable position, the second pin passes through the second plug hole and is positioned and connected to the telescopic rod through the connecting hole. Then the laser pointer is fixedly connected to the telescopic rod through the mounting circular groove, and measurement can be performed.

[0012] Beneficial effects of the utility model:

[0013] 1. In the past, most of the stakeout rods were integrated. Since the construction site often has limited space and many equipment, the stakeout rod may cause potential tripping or collision risks on the construction site, affecting the construction safety. The difference is that after the length is adjusted, hold the handle and measure with the laser pointer. During this process, the groove can increase the friction to prevent the stakeout rod from slipping during measurement. After the measurement is completed, remove the laser pointer, the first pin and the second pin in turn, then move the telescopic sleeve and the telescopic rod back into the sleeve, and then manually rotate the rotating cover. The rotating cover is rotatably connected to the sleeve through the connecting shaft, so that the rotating cover and the sleeve are closed, and then the elastic connecting belt passes through the circular hole through the positioning button to position and connect with the sleeve. Finally, by lifting the handle, the sleeve is driven to move to the next position to be measured to avoid potential tripping or collision risks on the construction site.

[0014] 2. First, manually adjust the telescopic sleeve to move out along the sleeve. After it moves to the appropriate position, the first pin passes through the first plug hole and is positioned and connected to the telescopic sleeve through the positioning hole. Then, the telescopic rod is moved out along the telescopic sleeve. After it moves to the appropriate position, the second pin passes through the second plug hole and is positioned and connected to the telescopic rod through the connecting hole. Then, the laser pointer is fixedly connected to the telescopic rod through the mounting circular groove. BRIEF DESCRIPTION OF THE DRAWINGS
