Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and more specifically, it relates to a tunnel construction angle auxiliary adjustment device. Background Technology

[0002] Tunnels are transportation passages that traverse mountains, water bodies, or underground, constructed using methods such as drill-and-blast, shield tunneling, or TBM (Tunnel Boring Machine). Construction requires precise axis control, real-time monitoring of geological changes, and simultaneous support lining to ensure structural stability. Through intelligent measurement, automated tunneling, and information management, modern tunnel engineering balances efficiency and safety, and is widely used in railway, highway, and urban rail transit construction.

[0003] During tunnel construction, total stations are used to assist in measuring and adjusting the tunnel's operating angle. Most existing total stations are supported by tripods. For example, a tunnel surveying total station disclosed in Chinese patent document CN212903217U uses a tripod structure to support the total station. However, when the above total station is in use, its bottom support feet are supported by support blocks, resulting in poor contact stability with the ground, which affects the support angle of the total station during use.

[0004] In addition, some tripods used to support total stations have fixed feet at the bottom and are fixed to the ground by means of ground nails or other fixing nail structures. However, the above method is not convenient for quick removal of the fixing nails after use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a tunnel construction angle auxiliary adjustment device to solve the technical problem mentioned in the background art of poor support stability of the tripod structure used to support the total station in the tunnel construction angle auxiliary adjustment device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A tunnel construction angle adjustment auxiliary device includes a base with a movable wheel at the bottom and a fixed seat at the top. A lifting seat is mounted on the fixed seat, and a mounting seat is mounted on the top of the lifting seat. A total station is mounted on the mounting seat. A mounting collar is mounted on the fixed seat, and a second locking member is threaded onto the mounting collar. The inner end of the second locking member presses against the outer side of the fixed seat. A support leg is retractably hinged to the outer side of the mounting collar, and a fixed foot is hinged to the bottom of the support leg. A lifting plate is hinged to the fixed foot, and a fixing hole is formed on the lifting plate and the fixed foot. A fixing nail for fixing the adjustment device is also installed on the fixed foot. The fixing nail passes through the fixing hole, through the lifting plate, through the fixed foot, and inserts into the ground. The bottom of the nail head abuts against the portion of the lifting plate located around the fixing hole.

[0010] The present invention is further configured such that the lifting plate includes a foot-operated end and a lifting end, and a connecting end is provided between the foot-operated end and the lifting end. The connecting end is hinged to the fixed foot, and the fixing hole is opened on the lifting end. The lifting end can fit against the fixed foot. When it is necessary to lift the fixing nail from the ground, the foot-operated end can be stepped on. Under the action of leverage, the connecting end drives the lifting end to lift up, thereby lifting the fixing nail upward through the lifting end, which facilitates the disassembly of the fixing nail. Therefore, no additional tools are required, and it is convenient and flexible to use.

[0011] The present invention is further provided with anti-slip texture on the top of the pedal end, which can improve the stability of the pedal end when pedaling.

[0012] The present invention is further configured such that the fixed base has a lifting groove, the bottom end of the lifting base is slidably located in the lifting groove, and the fixed base is threaded with a first locking member. The inner end of the first locking member abuts against the side wall of the lifting base. The lifting groove enables the lifting adjustment of the lifting base on the fixed base, thereby enabling flexible adjustment of the detection height when the total station is in use. After adjusting to a suitable position, the first locking member is tightened, and the lifting base is locked and fixed in the lifting groove, thereby achieving stable support for the total station when performing auxiliary angle measurement in tunnel construction.

[0013] The present invention is further configured such that the support leg includes a fixed leg, the top end of the fixed leg is hinged to the mounting collar, and the bottom end is provided with a telescopic leg, the bottom end of the telescopic leg is hinged to the fixed leg. Through the cooperation of the fixed leg and the telescopic leg, the support leg can be flexibly extended and retracted, thereby improving the overall support flexibility and stability.

[0014] The present invention is further configured such that a telescopic groove is provided on the fixed leg, the top end of the telescopic leg is limited to slide within the telescopic groove, and a third locking member is provided on the threaded side wall of the fixed leg. The inner end of the third locking member abuts against the side wall of the telescopic leg. Tightening the third locking member causes the inner end of the third locking member to abut against the telescopic leg, thereby locking and fixing the telescopic leg on the fixed leg, thus achieving overall stable support.

[0015] The present invention is further configured such that a clamping collar is provided on the fixed base, the clamping collar is located below the mounting collar, and a connecting post is provided between the clamping collar and the mounting collar. The clamping collar is provided with a clamping structure, and the synchronous movement of the clamping collar and the mounting collar can be realized through the connecting post, thereby maintaining the positional fit between the clamping groove and the fixed leg.

[0016] The present invention is further configured such that the clamping structure includes a clamping block, the clamping block is circumferentially disposed on the clamping collar, and the clamping block is provided with a clamping groove, the clamping groove engaging with the fixing column. When the whole is moved, the fixing leg carrying the telescopic leg can be clamped and fixed in the corresponding clamping groove, thereby fixing the support leg and improving the overall stability of use.

[0019] 1. This utility model has a fixed base at the top of the base, a lifting base that can be raised and lowered on the fixed base, and a mounting base at the top of the lifting base. The total station is mounted on the mounting base. In this way, the total station can be flexibly adjusted in terms of measurement height when the fixed base and the lifting base cooperate to flexibly control the angle auxiliary measurement of the total station in tunnel construction.

[0020] 2. This utility model has an installation collar on the fixed base, and a second locking member is threaded on the installation collar. The inner end of the second locking member presses against the outer side of the fixed base. The outer side of the installation collar is provided with a support leg that can be telescopically hinged. The support leg includes a fixed leg and a telescopic leg that cooperate with each other. In this way, the length of the support leg can be flexibly adjusted to provide stable support for the total station to perform auxiliary angle measurement in tunnel construction for different terrains.

[0021] 3. This utility model features a fixed foot hinged to the bottom of the support leg, with a lifting plate hinged to the fixed foot. The lifting plate and the fixed foot have mating holes for fixing nails. After adjusting the support leg to a suitable length so that the fixed foot is in contact with the ground, the fixing nails are passed through the fixing holes on the lifting plate and the fixed foot and inserted into the ground. The length of the support leg is then fixed, achieving stable overall support. In this utility model, the lifting plate includes a foot-operated end, a connecting end, and a lifting end. When not in use, stepping on the foot-operated end allows the lifting end to easily lift the fixing nails, improving ease of use and flexibility. Attached Figure Description
