Abstract
Description
Technical Field
[0001] This application relates to the field of total station foundation pit tilt terrain monitoring technology, and in particular to a stable connection bracket for total station foundation pit tilt terrain monitoring. Background Technology
[0002] The total station foundation pit tilt terrain monitoring connection frame is a device used in foundation pit engineering, especially when the surrounding terrain is uneven or tilted, to ensure accurate monitoring and stable installation of the total station. Foundation pit engineering typically requires monitoring changes in the surrounding soil, settlement of the pit sidewalls, and overall deformation. Therefore, ensuring stable installation of the total station and real-time data acquisition is crucial. The tilt terrain monitoring connection frame is designed to solve this problem, providing a stable installation platform and support frame for accurate monitoring in complex terrain.
[0003] The existing total station foundation pit tilt terrain monitoring connection frame consists of a support base, a bubble level mounted on the support base, and three telescopic outriggers that are hinged in a ring at the bottom of the support base. When using this type of total station foundation pit tilt terrain monitoring connection frame, the telescopic outriggers are first manually opened, and then the support base is placed horizontally at the monitoring position of the foundation pit tilt terrain with the help of the telescopic outriggers. Finally, the total station is fixed to the support base by tightening bolts, thereby providing stable support for the total station and ensuring convenient monitoring of the foundation pit tilt terrain.
[0004] While existing total station pit tilt terrain monitoring connection frames can provide stable support for the total station, the use of screw bolts to fix the total station makes the installation process cumbersome and inconvenient for efficient installation and use. Furthermore, when manually opening and closing the telescopic outriggers, the outriggers can only maintain stable support at the maximum opening angle, making it impossible to quickly and stably place the connection frame on small, flat areas within the pit, thus hindering the rapid and stable erection of the connection frame. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a stable connection bracket for monitoring the tilted terrain of a total station pit, which can both quickly clamp and limit the total station and enable the entire support frame to be quickly and stably placed on a small, flat area within the pit.

Three telescopic legs are annularly hinged around the bottom end of the mounting base. A retraction mechanism is installed between the bottom end of the mounting cover and the three telescopic legs. The retraction mechanism includes an electric telescopic rod, a connecting rod, and a connecting platform. The electric telescopic rod is located in the middle of the bottom end of the mounting cover. The connecting platform is located in the telescopic part of the electric telescopic rod.

This enables rapid clamping and limiting of the total station, facilitating efficient installation and use. Simultaneously, a retraction mechanism consisting of an electric telescopic rod, a connecting rod, and a connecting platform is installed on the mounting cover at the bottom of the mounting base.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the existing total station foundation pit tilt terrain monitoring connection frame will be introduced first.
[0025] The existing total station foundation pit tilt terrain monitoring connection frame consists of a support base, a bubble level mounted on the support base, and three telescopic outriggers that are hinged in a ring at the bottom of the support base. When using this type of total station foundation pit tilt terrain monitoring connection frame, the telescopic outriggers are first manually opened, and then the support base is placed horizontally at the monitoring position of the foundation pit tilt terrain with the help of the telescopic outriggers. Finally, the total station is fixed to the support base by tightening bolts, thereby providing stable support for the total station and ensuring convenient monitoring of the foundation pit tilt terrain.
[0026] Please see Figures 1-3 This application discloses a stable connection bracket for monitoring the inclined terrain of a total station pit. It includes a mounting base 2, with a positioning column 8 installed at the center of the top of the mounting base 2. A quick-installation mechanism 9 is installed inside the mounting base 2. The quick-installation mechanism 9 includes a limiting clamp 91, a sliding groove 92, a lead screw 93, a second bevel gear 94, a motor 95, and a first bevel gear 96. The motor 95 is located at the center of the bottom of the mounting base 2. The first bevel gear 96 is connected to the power output end of the motor 95. There are four second bevel gears 94 arranged in a ring on the upper side of the first bevel gear 94. Each second bevel gear 94 has a corresponding bevel gear 96 connected to the center of its sidewall facing away from the first bevel gear 96. A lead screw 93 is connected to a limit clamp 91 at one end away from the bevel gear 94. A slide groove 92 is opened on the mounting base 2 at the limit clamp 91. The bottom of the mounting base 2 is located outside the motor 95 and a mounting cover 6 is also installed. Three telescopic legs 4 are annularly hinged around the bottom of the mounting base 2. A retraction mechanism 5 is installed between the bottom of the mounting cover 6 and the three telescopic legs 4. The retraction mechanism 5 includes an electric telescopic rod 51, a connecting rod 52 and a connecting platform 53. The electric telescopic rod 51 is located in the middle of the bottom of the mounting cover 6, the connecting platform 53 is located in the telescopic part of the electric telescopic rod 51, and the connecting rod 52 is located between the telescopic legs 4 and the connecting platform 53.
[0027] Specifically, when placing the connecting bracket at the monitoring position in the pit, the connecting platform 53 is first moved down by the electric telescopic rod 51. After the connecting platform 53 moves down, the telescopic legs 4 are opened by the connecting rod 52 so that the mounting base 2 can be placed horizontally and stably by the telescopic legs 4 after they are opened. Then, the total station is initially limited on the mounting base 2 by the positioning column 8, and the bevel gear 96 is rotated by the motor 95 so that after the bevel gear 96 rotates, the clamping plate moves closer to the base of the total station after it is placed on the mounting base 2 by means of the bevel gear 94 and the screw, so as to achieve quick clamping and limiting of the total station.
[0028] Please see Figure 1 A bubble level 1 is also installed on one side of the top of the mounting base 2. An operation panel 7 is installed on the outer wall of the mounting base 2. A storage battery 3 is also installed on one side wall of the mounting cover 6.
[0029] In one implementation, when placing the connecting bracket, the level of the mounting base 2 is precisely adjusted by observing the position of the bubble in the bubble level 1. The battery 3 is mainly used to power the motor 95 and the electric telescopic rod 51 to ensure that the motor 95 and the electric telescopic rod 51 are powered and working normally.
[0030] Please see Figure 1 The control panel 7 is electrically connected to the motor 95 and the electric telescopic rod 51.
[0031] As one implementation method, the operation panel 7 mainly functions as a master switch, and mainly controls the on and off of the circuit to achieve coordinated operation of the motor 95 and the electric telescopic rod 51.
[0032] Please see Figure 2 Motor 95 is keyed to bevel gear 96, and bevel gear 96 meshes with bevel gear 94.
[0033] In one implementation, motor 95 is a three-phase geared motor 95 that can rotate in both directions. It is mainly used to provide power for the rotation of bevel gear 96 so that bevel gear 94 can rotate easily after bevel gear 96 rotates.
[0034] Please see Figure 2 The lead screw 93 is rotatably engaged with the mounting base 2, and the lead screw 93 passes through the limiting clamp 91 and is threadedly connected to the limiting clamp 91.
[0035] As one implementation method, the rotating fit installation method makes it easier for the lead screw 93 to rotate relative to the mounting base 2. At the same time, after the lead screw 93 rotates, the limiting clamp 91 will move along the slide groove 92 under the action of thread transmission, so as to realize the initial clamping and limiting of the total station base, eliminating the cumbersome operation of tightening bolts to connect and fix the total station.
[0036] Please see Figure 2 The mounting base 2 has a hollow structure located at bevel gear 96 and bevel gear 94.
[0037] As one implementation method, the hollow structure design of the mounting base 2 provides sufficient installation space for bevel gear 1 96 and bevel gear 2 94.
[0038] Please see Figure 1 , Figure 2 and Figure 4 The limiting clamp 91 has an inverted L-shaped structure, and the clamping wall of the limiting clamp 91 has an arc-shaped clamping groove.
[0039] As one implementation method, the reserved arc-shaped clamping groove on the limiting clamping plate 91 can ensure that the limiting clamping plate 91 can have a larger clamping area with the outer wall of the circular base of the total station when clamping.
[0040] Please see Figure 1 and Figure 3 The fixed part of the electric telescopic pole 51 is bolted to the mounting cover 6, and the telescopic part of the electric telescopic pole 51 is bolted to the connecting platform 53.
[0041] As one implementation method, the electric telescopic rod 51 is mainly used to realize the on-demand lifting and lowering of the connecting platform 53, so that during the lifting and lowering of the connecting platform 53, the connecting rod 52 can be used to realize the synchronous opening and closing of each telescopic leg 4. At the same time, by controlling the extension and retraction length of the electric telescopic rod 51, the opening and closing angle of each telescopic leg 4 can be synchronously limited, which facilitates the rapid and stable placement of the device on a small flat ground in the pit.
[0042] Please see Figure 1 and Figure 3 One end of the connecting rod 52 is hinged to the sleeve rod on the telescopic outrigger 4, and the other end is hinged to the connecting platform 53.
[0043] As one implementation method, the hinged connection makes it more convenient to adjust the rotation of the connecting rod 52 relative to the telescopic outrigger 4 and the connecting platform 53.
[0044] The specific working principle is as follows: When placing the connecting bracket at the monitoring position in the foundation pit, the connecting platform 53 is first lowered under the action of the electric telescopic rod 51. After the connecting platform 53 is lowered, the telescopic legs 4 are opened under the action of the connecting rod 52, so that the mounting base 2 can be placed horizontally and stably under the action of the opened telescopic legs 4. Then, the total station is initially limited on the mounting base 2 under the action of the positioning column 8, and the bevel gear 96 is rotated by the motor 95. After the bevel gear 96 rotates, the clamping plate moves closer to the base of the total station placed on the mounting base 2 with the help of the bevel gear 94 and the screw, so as to achieve rapid clamping and limiting of the total station. After the total station is installed and limited, it can be used to monitor the tilted terrain of the foundation pit. During the use of the connecting bracket, the quick-installation mechanism 9 enables the total station to be quickly clamped and limited, which facilitates the efficient installation and use of the total station. At the same time, by installing the retraction mechanism 5, which consists of an electric telescopic rod 51, a connecting rod 52, and a connecting platform 53, on the mounting cover 6 at the bottom of the mounting base 2, the electric telescopic rod 51, the connecting rod, and the connecting rod 52 can be used to achieve stable limiting of each telescopic leg 4 at different opening and closing angles. This facilitates the rapid and stable placement of the connecting bracket on a small, flat area within the foundation pit, and makes the efficient erection and use of the connecting bracket convenient.
[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
