Description

Technical Field

[0001] This utility model relates to the field of positioning mechanism technology, specifically a foundation pit excavation positioning mechanism. Background Technology

[0002] An investigation revealed that a Chinese utility model patent (publication number: CN221029554U) discloses a positioning device for excavating a building foundation pit. The device includes a roller, a forward tube on one side of the roller, and a feeding mechanism above the forward tube. The feeding mechanism is used to introduce marking powder into the forward tube. An auger is rotatably installed on the inner wall of the forward tube, with one end of the auger fixedly mounted on the surface of the roller. In use, the user places the roller on the ground and drives it to roll using a drive mechanism. This causes the marking powder fed into the forward tube to move forward until it exits from the outlet. This design allows the user to mark lines simply by driving the roller, and the marking powder is evenly distributed under gravity, saving manpower on manual powder application and ensuring the quality of the marking, thus fully demonstrating the device's practicality.

[0003] Although the aforementioned patent saves manpower for manually sprinkling powder and the powder is sprinkled more evenly, it still requires manual pushing of the device. When manually pushing the device to sprinkle powder, it is difficult to ensure that the device will not deviate. Furthermore, since the device only has one roller, the direction of the device is more difficult to control, resulting in the drawn lines not overlapping with the laid lines, thus affecting the quality of the drawn lines.

[0004] Therefore, this utility model provides a foundation pit excavation positioning mechanism to solve the above problems. Utility Model Content

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A foundation pit excavation positioning mechanism includes a marking machine body and two rollers. Two fixing blocks are fixedly connected to the side of the marking machine body, and the two fixing blocks are symmetrically arranged. Mounting boxes are provided on both sides of the marking machine body. Rotating rods are rotatably connected inside the mounting boxes. A motor is fixedly connected to one side of the mounting box. Two main ropes are provided between the two mounting boxes. Branch ropes are fixedly connected to the main ropes. Insert blocks are fixedly connected to the other end of the branch ropes. Two connecting rods are fixedly connected to the bottom of the mounting boxes. A base plate is provided at the bottom of the connecting rods. A sliding plate is slidably connected between the two connecting rods. Multiple inserts are fixedly connected to the bottom of the sliding plate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a foundation pit excavation positioning mechanism, such as... Figures 1-5 As shown, the device includes a line marking machine body 1 and two rollers 2. The two rollers 2 help maintain the stability of the device. Two fixing blocks 3 are fixedly connected to the side of the line marking machine body 1, and the two fixing blocks 3 are symmetrically arranged. There are mounting boxes 4 on both sides of the line marking machine body 1. A rotating rod 6 is rotatably connected inside the mounting box 4. A motor 5 is fixedly connected to one side of the mounting box 4. The motor 5 is existing technology and will not be described in detail here. There are two main ropes 7 between the two mounting boxes 4. A branch rope 13 is fixedly connected to the main rope 7. A plug 14 is fixedly connected to the other end of the branch rope 13. Two connecting rods 8 are fixedly connected to the bottom of the mounting box 4. A base plate 9 is provided at the bottom of the connecting rods 8. A sliding plate 11 is slidably connected between the two connecting rods 8. Multiple stakes 12 are fixedly connected to the bottom of the sliding plate 11. The stakes 12 are used to fix the device.

[0017] The other end of each of the two fixing blocks 3 is provided with a groove 15, and the groove 15 corresponds to the insertion block 14. The fixing block 3 and the insertion block 14 are respectively provided with a first insertion hole 16 and a second insertion hole 17, and the first insertion hole 16 and the second insertion hole 17.

[0018] The fixing block 3 and the insert block 14 are connected by bolts 18. Both ends of the bolts 18 pass through the first insert hole 16 and the second insert hole 17 and extend out a part. The bolts 18 can connect the main body 1 of the line marking machine to the main rope 7.

[0019] Both ends of the main rope 7 pass through an installation box 4 and are wrapped around the rotating rod 6. One end of the rotating rod 6 passes through the installation box 4 and is fixedly connected to the output end of the motor 5.

[0020] The base plate 9 is provided with an opening 10, and the opening 10 corresponds to the stake 12. The width of the opening 10 is not less than the diameter of the stake 12.

[0021] The width of the skateboard 11 is greater than that of the base plate 9, and the base plate 9 is fixedly connected to the connecting rod 8.

[0022] Specifically, before drawing the line, insert the insert 14 into the groove 15 of the fixing block 3 and fix the fixing block 3 and the insert 14 with bolts 18 to assemble the equipment. Then, place the two mounting boxes 4 at the two ends of the line to be drawn. At this time, the main body 1 of the line drawing machine is located at one end of the line to be drawn, and the discharge port of the main body 1 of the line drawing machine corresponds to the line to be drawn. Then, press the slide plate 11 down to make the insert 12 move along with it until the slide plate 11 is in contact with the base plate 9. During this process, the insert 12 will pass through the opening 10 and be inserted into the soil to fix the corresponding device.

[0023] Once the device is fixed in place, the two motors 5 are started simultaneously. When the motors 5 start, they drive the rotating rods 6 to rotate. As the rotating rods 6 rotate, they release or retract the main rope 7. The rotating rods 6 closer to the main body 1 of the line marking machine will release the line, while those farther away will retract the line. As a result, the main rope 7 will move to one end. When the main rope 7 moves, it will also move the branch ropes 13. The movement of the branch ropes 13 will also move the insert block 14, which in turn will move the fixing block 3, the main body 1 of the line marking machine, and the rollers 2. Due to the friction between the ground and the rollers 2, the rollers 2 will rotate and draw lines. During this process, no manual pushing device is required, thus reducing labor costs. Moreover, the two symmetrical main ropes 7 simultaneously pull the main body 1 of the line marking machine forward. With the arrangement of the two rollers 2, the main body 1 of the line marking machine can be prevented from deviating from its direction. In addition, the uniform rotation of the motors 5 will keep the moving speed of the main body 1 of the line marking machine constant, resulting in more even powder application.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
