Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for road and bridge surveying, and in particular to a device for placing a measuring rod for road and bridge surveying. Background Technology

[0002] When surveying roads and bridges, either a leveling rod or a leveling rod will be used depending on the actual situation. When using a leveling rod, the staff needs to support it to a vertical position, which requires considerable effort to keep it level. If the leveling rod wobbles during measurement, it will affect the accuracy of the measurement data. Also, when supporting the leveling rod, it is easy for it to detach from the base, requiring the staff to adjust it back and forth, which brings inconvenience to the measurement work. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model discloses a bridge and road surveying gantry rod placement device. This utility model facilitates the fixation of the leveled gantry rod by the staff, preventing the gantry rod from shaking during measurement and preventing the gantry rod from falling off the base. The auxiliary support mechanism fixes the leveled gantry rod to prevent it from tilting or shaking during measurement.

[0004] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0005] A bridge and road surveying measuring rod placement device includes a base, on which a universal joint is mounted, and an auxiliary support mechanism is mounted on the end of the universal joint away from the base.

[0006] The universal joint is located in the middle of the base.

[0007] The auxiliary support mechanism includes a telescopic rod, a sliding frame, a support plate, and a placement frame. The placement frame is located on the end of the universal joint away from the base and is fixedly connected. The placement frame is fixedly connected with telescopic rods arranged at equal intervals. The telescopic end of the telescopic rod is fixedly connected with a sliding frame, and the sliding frame is fixedly connected with a support plate.

[0008] The position of the central axis of the placement frame coincides with the position of the central axis of the universal joint.

[0009] The position of the central axis of the sliding frame coincides with the position of the central axis of the placement frame.

[0010] The support plate is an inclined plate, and the bottom end of the support plate is provided with insertion teeth.

[0011] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0012] The present invention provides a bridge and road surveying gantry placement device that facilitates the fixation of the leveled gantry by staff, preventing wobbling during measurement and preventing the gantry from detaching from the base. The auxiliary support mechanism fixes the leveled gantry in place, preventing it from tilting or wobbling during measurement. Attached Figure Description

[0017] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Combined with appendix Figures 1-3 The aforementioned bridge and road surveying measuring rod placement device includes a base 1, and a universal joint 2 is installed on the base 1. An auxiliary support mechanism 3 is installed on the end of the universal joint 2 away from the base 1.

[0019] The universal joint 2 is located in the middle of the base 1.

[0020] The auxiliary support mechanism 3 includes a telescopic rod 301, a sliding frame 302, a support plate 303, and a placement frame 304. The placement frame 304 is located on the end of the universal joint 2 away from the base 1 and is fixedly connected. The telescopic rods 301 are fixedly connected at equal intervals on the placement frame 304. The sliding frame 302 is fixedly connected to the telescopic end of the telescopic rod 301, and the support plate 303 is fixedly connected to the sliding frame 302. The placement frame 304 is provided with an anti-slip pad to prevent the placement frame 304 from detaching from the tower gauge when the tower gauge is moved, thus fixing the auxiliary support mechanism 3 together with the tower gauge and eliminating the need to pick it up separately.

[0021] The position of the central axis of the placement frame 304 coincides with the position of the central axis of the universal joint 2.

[0022] The position of the central axis of the sliding frame 302 coincides with the position of the central axis of the placement frame 304.

[0023] The support plate 303 is an inclined plate, and the bottom end of the support plate 303 is provided with insertion teeth to facilitate the insertion of the support plate 303 into the soil.

[0024] The aforementioned bridge and road surveying leveling rod placement device involves the operator inserting the bottom end of the leveling rod into the placement frame 304. During measurement, the operator levels the leveling rod by referring to the level bubble on the leveling rod, using the base 1 where it contacts the ground. After leveling, the operator can step on the sliding frame 302 to lower it. This lowering of the sliding frame 302 causes the support plate 303 to move downwards, allowing its bottom end to insert into the ground. The support plate 303 then supports the leveled leveling rod, facilitating operation.

[0025] The parts of this utility model not described in detail are prior art. Although this utility model has been specifically shown and introduced in conjunction with preferred embodiments, there are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. However, those skilled in the art should understand that various changes in form and detail can be made to this utility model without departing from the spirit and scope of this utility model as defined by the appended claims, and all such changes shall be within the protection scope of this utility model.
