Description

Technical Field

[0001] The present invention relates to the technical field of distance meter support, in particular to a distance meter support device for road and bridge construction. Background Art

[0002] Road and bridge construction refers to the process of building roads and bridges in accordance with design drawings and construction specifications through a series of construction activities and technical measures to finally complete the construction of roads and bridges. In the process of road and bridge construction, the distance meter is one of the indispensable instruments. During the use of the distance meter, in order to ensure its stability, a support device will be set at its bottom to facilitate the use of the distance meter by subsequent staff.

[0003] At present, in order to ensure the accuracy of the measurement results of the rangefinder during the road and bridge construction process, the support device needs to be kept horizontal during the support process to avoid left and right tilting. Most of the existing support devices realize horizontal detection by observing whether the level bubble on the support platform is directly above the black spot, but there are generally large errors in human eye observation. At the same time, when the support device is slightly tilted, it may not be discovered by human eye observation alone, so the support device cannot be accurately leveled. Therefore, a rangefinder support device for road and bridge construction is urgently needed to solve the above problems. Summary of the invention

[0004] In view of the problems in the related art, the present invention proposes a distance meter support device for road and bridge construction to overcome the above technical problems existing in the existing related art.

[0009] An adjustment component is provided at the bottom of the truncated table;

[0010] A control panel is disposed on the top of the round table, and a battery pack is disposed inside the second support tube;

[0011] A leveling assembly is disposed inside the first supporting tube.

[0012] Through the above technical solution: the staff can judge the level of the entire support device by observing whether the value of the pressure sensor on the control panel of the round table exceeds the threshold, and can quickly judge without naked eye observation, thus meeting people's usage needs.

[0013] Furthermore, the adjustment assembly includes a second threaded screw fixedly connected to the outer wall of the bottom of the truncated table, the circumferential outer wall of the second threaded screw is meshed with a second threaded sleeve, one side outer wall of the second threaded sleeve is rotatably connected to a movable rod, and one end of the movable rod away from the second threaded sleeve is rotatably connected to the outer wall of one side of the support leg.

[0014] Through the above technical solution: it is possible to realize the simultaneous expansion and contraction of three groups of supporting legs, which not only improves the adjustment efficiency of the supporting device, but also effectively avoids the situation where the supporting device is easily uneven due to independent adjustment of a single supporting leg.

[0015] Furthermore, the bottom outer wall of the second threaded screw is fixedly connected to a limit plate, and the bottom outer wall of the second threaded sleeve is fixedly connected to a turning handle.

[0016] Through the above technical solution: the limiting plate can effectively prevent the second threaded sleeve from sliding out of one end of the second threaded screw, and the turning handle can facilitate the staff to quickly rotate the threaded sleeve.

[0017] Further, the self-locking assembly includes a horizontal plate fixedly connected to the outer wall of one side of the first rotating seat, the outer wall of one side of the horizontal plate is rotatably connected to a first threaded screw, the end of the first threaded screw away from the horizontal plate is fixedly connected to a handle, the circumferential outer wall of the first threaded screw is meshed with a first threaded sleeve, the circumferential outer wall of the first threaded sleeve is fixedly connected to a rack, one end of the rotating rod is fixedly connected to a first gear, and the rack is meshed with the first gear.

[0018] Through the above technical scheme: the handle can drive the first threaded screw to rotate, and during the rotation of the first threaded screw, the threaded sleeve engaged on its outer wall can move horizontally, and the threaded sleeve is fixedly connected to the rack, so when the threaded sleeve moves horizontally, it can drive the rack to move horizontally together, and during the horizontal movement of the rack, it can drive the first gear to rotate, and the first gear is fixedly connected to the rotating rod, so the device can be quickly leveled when the rotating rod rotates, and after the leveling is completed, self-locking can be achieved through the rack, and there is no need to adjust the length of a single set of support legs to achieve leveling, which improves people's work efficiency and meets people's usage needs.

[0019] Furthermore, a guide rod is fixedly connected to an outer wall of one side of the transverse plate, a guide cylinder is sleeved on a circumferential outer wall of the guide rod, and the guide cylinder is fixedly connected to the first threaded sleeve.

[0020] Through the above technical solution: the sliding of the guide cylinder on the outer wall of the guide rod can play a good guiding and limiting role in the horizontal movement of the first threaded sleeve, ensuring that the first threaded sleeve can stably perform horizontal movement.

[0021] Furthermore, a storage groove is formed at one end of the support leg, a telescopic leg is inserted into the storage groove, a locking bolt is threadedly connected to an outer wall of one side of the support leg, and one end of the locking bolt is pressed against an outer wall of one side of the telescopic leg.

[0022] Through the above technical solution: the telescopic legs can supplement the length of the supporting legs, and after the telescopic legs are adjusted to a suitable length, they can be locked and fixed by rotating the locking bolts.

[0023] Furthermore, the leveling assembly includes a third rotating seat fixedly connected to the bottom outer wall of the support platform, the third rotating seat is rotatably connected to a rocker arm, one end of the rocker arm away from the third rotating seat is fixedly connected to a fixed seat, and a counterweight block is welded to the bottom of the fixed seat.

[0024] Through the above technical solution: when the supporting device tilts left or right, the counterweight block located inside the first supporting tube will still be in a vertical downward state due to the gravity factor.

[0025] Furthermore, an arc-shaped plate is fixedly connected to the outer wall of the swing rod, and tooth grooves are provided on the circumferential outer wall of the arc-shaped plate. The number of the tooth grooves is two groups, and the two groups of tooth grooves are meshed with second gears.

[0026] Through the above technical solution: when the counterweight block and the rocker arm rotate from an inclined state to a vertical downward state, the rocker arm can drive the arc plate fixed on its outer wall to rotate together, and the outer wall of the arc plate is provided with a tooth groove. When the arc plate swings, it will engage with the second gear through the tooth groove, thereby driving the second gear to rotate.

[0027] Furthermore, the circumferential outer wall of the second gear is fixedly connected to a second connecting plate, the circumferential inner wall of the first support cylinder is fixedly connected to a reinforcing plate, one side outer wall of the reinforcing plate is fixedly connected to the first connecting plate, one side outer wall of the first connecting plate is fixedly connected to a spring, and one end of the spring away from the first connecting plate is fixedly connected to the second connecting plate.

[0028] Through the above technical solution: the first connecting plate can be initially fixed to the second connecting plate by the spring.

[0029] Furthermore, a pressure sensor is provided between the first connecting plate and the second connecting plate, and two ends of the pressure sensor are movably connected to the first connecting plate and the second connecting plate respectively.

[0030] Through the above technical solution: during the rotation of the second gear, the second connecting plate can be driven to make a circular motion together. At the same time, a pressure sensor is arranged between the second connecting plate and the first connecting plate. When the second connecting plate rotates, the value of the pressure sensor will change immediately, so that people can be quickly reminded. Moreover, the diameter of the arc plate is much larger than the second gear, which can play a good role in speed increase. Therefore, when the swing arm swings slightly, the second gear will also produce a certain rotation to make the second connecting plate swing, thereby effectively expanding the detection accuracy of the entire adjustment component.

[0031] Beneficial effects of the present invention:

[0032] The present invention provides a rangefinder support device for road and bridge construction. Through the setting of an adjustment component, the second threaded sleeve can be driven to rotate through a turning handle. During the rotation of the second threaded sleeve, the outer wall of the second threaded screw can move up and down. At the same time, one end of the second threaded sleeve is rotatably connected to a movable rod, and the other end of the movable rod and the supporting leg also rotate. Therefore, in the process of the second threaded sleeve rising and falling, the three groups of supporting legs can be opened and closed at the same time, which not only improves the adjustment efficiency of the supporting device, but also effectively avoids the situation that the supporting device is uneven due to the independent adjustment of a single supporting leg.

[0033] The present invention provides a rangefinder support device for road and bridge construction. Workers can judge the level of the entire support device by observing whether the value of the pressure sensor on the control panel of the round table exceeds the threshold value. The staff can quickly judge without naked eye observation, which meets people's use needs. When the support device tilts left and right, the counterweight block located inside the first support tube will still be in a vertical downward state due to gravity. During this process, the counterweight block and the swing rod will rotate from the tilted state to the vertical downward state. During the rotation of the swing rod, the arc plate fixed on its outer wall can be driven to rotate together, and the outer wall of the arc plate is provided with tooth grooves. When the arc plate swings, it will mesh with the second gear through the tooth groove, thereby driving the second gear to rotate. During the rotation of the second gear, it can drive the second connecting plate to make a circular motion. At the same time, a pressure sensor is arranged between the second connecting plate and the first connecting plate. When the second connecting plate rotates, the value of the pressure sensor will change immediately, so that people can be quickly reminded. Moreover, the diameter of the arc plate is much larger than the second gear, which can play a good role in speeding up. Therefore, when the swing arm swings slightly, the second gear will also produce a certain rotation to make the second connecting plate swing, thereby effectively expanding the detection accuracy of the entire adjustment component.

[0034] The present invention provides a rangefinder support device for road and bridge construction. Through the self-locking component, when the worker detects that the device has a certain inclination through a pressure sensor, the handle can be turned, and the first threaded screw can be driven to rotate through the handle. During the rotation of the first threaded screw, the threaded sleeve engaged on the outer wall thereof can be made to move horizontally, and the threaded sleeve is fixedly connected to the rack. Therefore, when the threaded sleeve moves horizontally, the rack can be driven to move horizontally together. During the horizontal movement of the rack, the first gear can be driven to rotate, and the first gear is fixedly connected to the rotating rod. Therefore, when the rotating rod rotates, the device can be quickly leveled. At the same time, after the leveling is completed, self-locking can be achieved through the rack, and there is no need to achieve leveling by adjusting the length of a single set of supporting legs, thereby improving people's work efficiency and meeting people's usage needs.
