Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a novel circular pipe jacking axis measuring tool. Background Technique

[0002] With the acceleration of the urbanization process, the construction demand for underground pipelines is increasing day by day. As an environmentally friendly underground pipeline construction method, pipe jacking construction technology will be more widely used in long-distance and large-diameter pipe jacking in the future. As one of the core technologies of pipe jacking construction, controlling the measurement accuracy is particularly crucial. At present, the main measurement methods for pipe jacking projects are as follows: 1. The first measurement method: The surveyor uses a total station to find the designed central axis in the pipe jacking working well, sets up a theodolite on the central axis, and judges whether the linear deviation of the jacking pipe exceeds the specification requirements by the distance between the infrared ray of the theodolite and the inner wall of the circular pipe of the pipe jacking. If it exceeds the specification requirements, the circular pipe of the pipe jacking needs to be adjusted, and its position is measured again after adjustment until the pipe deviation meets the specification and design requirements. This measurement method has a large measurement error in long-distance pipe jacking, and the geometric dimension deviation of the circular pipe also has a great influence on the measurement accuracy; 2. The second measurement method: The pipe jacking equipment adopts an automatic data transceiver and deviation correction system. Prisms and data transmission systems are installed on the pipeline to cooperate with the robot for automatic measurement. Due to the high cost of the whole set of equipment, it is generally only used in large-scale long-distance pipe jacking. Moreover, when the pipeline is jacked, it is necessary to frequently excavate and remove soil. The working space is narrow, which affects the measurement line of sight. The measurement workload is large, the efficiency is low, and the ventilation condition in the pipeline is poor, with many potential safety hazards.

[0003] In view of the deficiencies in the above technical background, some enterprises have also made measurement positioning frames, but they are all too heavy and cannot be reused according to the change of the diameter of the circular pipe of the pipe jacking. They are erected in the circular pipe and block the soil transportation. They need to be installed and removed at any time, and the measurement accuracy is not high. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel circular pipe jacking axis measuring tool. By setting an L-shaped sleeve, a sleeve, a telescopic rod, a rotating assembly and a clamping assembly, the problems of being too heavy, not being able to be reused according to the change of the diameter of the circular pipe of the pipe jacking, blocking the soil transportation when erected in the circular pipe, needing to be installed and removed at any time, and having low measurement accuracy are solved.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A novel circular pipe jacking axis measuring tool includes an L-shaped sleeve. One side of the L-shaped sleeve is fixedly connected with a hinge. The L-shaped sleeve is rotationally connected with a sleeve through the hinge. Telescopic rods are slidably connected inside the L-shaped sleeve and the sleeve. Rotating assemblies are fixedly connected to one side of the telescopic rod and the L-shaped sleeve respectively. A clamping assembly is fixedly connected to one end of the telescopic rod.

[0006] Preferably, the rotating assembly includes a bearing seat fixedly connected to one side of the telescopic rod and the L-shaped sleeve. The bearing seat is rotatably connected with a handle screw through a bearing. The surface of the handle screw is threadedly connected with a support rod. One end of the support rod is fixedly connected with a right-angle fixing piece. A jack is opened on one side of the right-angle fixing piece, and an expansion bolt is inserted into the jack.

[0007] Preferably, the clamping assembly includes a connecting rod fixedly connected to one end of the telescopic rod. A lock is rotatably connected to the surface of one of the connecting rods. A buckle groove is opened on one side of the lock, and the buckle groove is adapted to the connecting rod.

[0008] Preferably, magnetic suction seats are fixedly connected to one end of the connecting rod and the back surface of the L-shaped sleeve respectively, and a magnetic prism is adsorbed on one side of the magnetic suction seat.

[0009] Preferably, an installation groove is opened between the telescopic rods, and a bubble level is fixedly installed inside the installation groove.

[0010] The utility model provides a new type of circular pipe jacking axis measuring tool, which has the following beneficial effects:

[0011] There is no need for surveyors to work in the pipeline for a long time. Especially when the pipe jacking reaches a certain depth, the risks of object strikes and asphyxiation are avoided, and the problem of limited working surface is solved. The observer can measure the axis of the pipe jacking at any time, avoiding rework of pipe adjustment, which is beneficial to speeding up the construction progress. The surveyor can measure as the pipe jacks, increasing effective process control, ensuring the accuracy of pipe jacking, with high measurement accuracy, simple structure, convenient installation, disassembly and portability, applicable to the axis measurement of circular pipe jacks of various diameters, and installed on the inner wall of the circular pipe without affecting transportation and passage. By programming a small program for calculating the center coordinates, the calculation is accurate and fast. BRIEF DESCRIPTION OF THE DRAWINGS

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, this embodiment provides a new type of circular pipe jacking axis measuring tool, including an L-shaped sleeve 1. One side of the L-shaped sleeve 1 is fixedly connected with a hinge. The L-shaped sleeve 1 is rotatably connected with a sleeve 2 through the hinge. Telescopic rods 3 are slidably connected inside both the L-shaped sleeve 1 and the sleeve 2. Rotating components are fixedly connected to one side of both the telescopic rod 3 and the L-shaped sleeve 1. One end of the telescopic rod 3 is fixedly connected with a clamping component. During use, the L-shaped sleeve 1 and the sleeve 2 can rotate at an angle through the hinge, and by extending the telescopic rods 3, the included angle between the two telescopic rods 3 is fixed to be less than 180° on the inner wall of the circular pipe jacking.

[0022] The rotating assembly includes a bearing seat 4 fixedly connected to one side of the telescopic rod 3 and the L-shaped sleeve 1. The bearing seat 4 is rotatably connected with a handle screw 5 through a bearing. The surface of the handle screw 5 is threadedly connected with a support rod 6. One end of the support rod 6 is fixedly connected with a right-angle fixing piece 7. A jack is opened on one side of the right-angle fixing piece 7, and an expansion bolt 8 is inserted into the inside of the jack. After adjusting the position of the telescopic rod 3, the three right-angle fixing pieces 7 in this device are fixed to the inner wall of the circular jacking pipe through the expansion bolt 8 to realize the fixation of this device. And when in use, the operator can rotate the handle screw 5 to finely adjust the position of the telescopic rod 3 on the right-angle fixing piece 7 to keep it vertical, so that the measurement data is more accurate. Moreover, it is installed on the side wall of the circular pipe of the jacking pipe, does not need to be installed and disassembled multiple times, does not affect the passage and transportation inside the circular pipe of the jacking pipe, ensures the smoothness of the passage, and reduces potential safety hazards.

[0023] The clamping and fixing assembly includes a connecting rod 9 fixedly connected to one end of the telescopic rod 3. A lock catch 10 is rotatably connected to the surface of one of the connecting rods 9. A buckle groove is opened on one side of the lock catch 10, and the buckle groove is adapted to the connecting rod 9. When this device is not in use, the L-shaped sleeve 1 and the sleeve 2 can be brought together, and the lock catch 10 is sleeved on the other connecting rod 9 to fix the positions of the two connecting rods 9, thereby fixing the positions of the two telescopic rods 3. It is foldable and convenient for personnel to carry, and at the same time occupies a small space.

[0024] A magnetic seat 11 is fixedly connected to one end of the connecting rod 9 and the back of the L-shaped sleeve 1. A magnetic prism 12 is adsorbed on one side of the magnetic seat 11. After the device is installed in the circular jacking pipe, the magnetic prism 12 can be adsorbed on the magnetic seat 11. By measuring the center point coordinates A(X1, Y1, Z1), B(X2, Y2, Z2), C(X3, Y3, Z3) of the magnetic prism 12 at the ends of the two telescopic rods 3 and on the back of the L-shaped sleeve 1, and inputting them into the mini-program, the center coordinates O(X0, Y0, Z0) of the circumcircle tangent to points A, B, and C can be calculated. Connect the center O point with the starting point center O〞, and the deviation of the circular pipe of the jacking pipe can be calculated by comparing with the axial direction of the design drawing. When in specific use, it is necessary to make the three magnetic prisms 12 tangent to the inner wall of the circular jacking pipe, so as to facilitate the subsequent measurement of the circular jacking pipe. The magnetic prism 12 adopts a special prism for total station. Even if the light in the circular pipe of the jacking pipe is insufficient, it does not affect the measurement. The magnetism can directly adsorb on the magnetic seat 11, which is convenient for installation and disassembly and is not easy to be damaged or lost.

[0025] An installation groove 13 is opened between the telescopic rods 3, and a bubble level 14 is fixedly installed inside the installation groove 13. After the device is installed, it can be observed through the bubble level 14 whether the telescopic rods 3 are kept vertical, so that the operator can finely adjust the telescopic rods 3 through the handle screw 5 to keep them vertical, thereby improving the accuracy of the subsequent measurement data.

[0026] The center coordinates are calculated by programming a small program, which is accurate and fast. The pipe jacking circular pipe can be adjusted quickly through the data, avoiding rework.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
