Description

Technical Field

[0001] This utility model relates to the field of engineering surveying supports, and in particular to an engineering surveying exploration support. Background Technology

[0002] In the field of modern engineering construction, the implementation of projects such as building, transportation, and geological exploration all rely on precise engineering surveying. As the "eyes" of engineering construction, the accuracy of engineering surveying data directly affects the design, construction quality, and subsequent safety of the project. Survey supports, as key equipment used to fix measuring instruments during engineering surveying, have a significant impact on the accuracy of the measurement results.

[0003] Existing supports typically have a dedicated mounting base at the top for installing measuring instruments, and a pad at the bottom for supporting the ground. After long-term use, the pad is prone to wear due to frequent friction with the ground. Replacing the pads on existing supports is complicated, often requiring the disassembly of multiple parts with specialized tools, making the replacement difficult and cumbersome. In response to this technical problem, this application proposes a survey support for engineering surveying. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an engineering surveying support. By pressing the movable plate to compress the spring, the protrusion disengages from the groove. Rotating the rotating rod drives the teeth and the insertion rod, removing the insertion rod from the insertion hole of the insertion block and releasing the limiting position, allowing the insertion block to be pulled out for replacement. Timely replacement of worn insertion blocks effectively prevents the support from tilting due to uneven wear of components, ensuring the support remains stable during use. The replacement process is convenient, greatly reducing the difficulty of replacing the pad blocks. Through the cooperation of the movable support rod and the fixed support rod, the height of the mounting body can be flexibly adjusted according to the actual usage scenario. The movable support rod is pulled out from the bottom of the housing and fixed, and then the fixed support rod is unfolded, completing the deployment with the pad block in contact with the ground. This allows the support to adapt to working environments with different height requirements, effectively improving the versatility and practicality of the support.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An engineering surveying support includes a mounting base body. Multiple rotating blocks are rotatably connected to the outer periphery of the mounting base body. A fixed support rod is bolted to the bottom of each rotating block. A housing is fixedly connected to the outer wall of the fixed support rod. A movable support rod is slidably connected to the bottom of the housing. Pads are provided at the bottom of the movable support rod and the bottom of the fixed support rod. Two insert blocks are fixedly connected to the bottom of each pad. Insert holes are formed on the outer walls of each insert block, and insert rods are placed within the insertion holes. Limiting components are provided on the adjacent sides of the two insert rods.

[0007] Furthermore, the limiting component includes a rotating rod located on a similar side of the two insert rods, the outer wall of the rotating rod is fixedly connected with teeth, the teeth mesh with the outer wall of the insert rod, and a movable plate is sleeved on the outer wall of the rotating rod at the end away from the teeth.

[0008] Furthermore, a groove is provided in the middle of the movable plate, and a protrusion is provided in the groove. The protrusion is fixedly connected to the outer wall of the rotating rod at the end away from the teeth.

[0009] Furthermore, two sliding rods are fixedly connected to the side of the movable plate near the insertion rod.

[0010] Furthermore, a spring is sleeved on the outer wall of the middle end of the rotating rod, one end of the spring is connected to the movable plate, and the other end of the spring is connected to the outer wall of the fixed support rod or the movable support rod.

[0011] Furthermore, the two insertion holes on the outer walls of the two insertion blocks are located at the top and the bottom, respectively.

[0012] Furthermore, a knob is provided on the outer wall of the housing.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by pressing the moving plate to compress the spring, the protrusion is disengaged from the groove. The rotating rod drives the teeth and the insertion rod to move the insertion rod out of the insertion hole of the insertion block to release the limit. The insertion block can then be pulled out for replacement. Timely replacement of worn insertion blocks can effectively prevent the bracket from tilting due to uneven wear of parts, ensuring that the bracket remains stable during use. The replacement process is relatively convenient and greatly reduces the difficulty of replacing the pad.

[0015] 2. In this utility model, the height of the mounting base body can be flexibly adjusted according to the actual use scenario by cooperating with the movable support rod and the fixed support rod. The movable support rod is pulled out from the bottom of the shell and fixed, and then the fixed support rod is unfolded. The deployment is completed with the pad block in contact with the ground, so that the bracket can adapt to working environments with different height requirements, effectively improving the versatility and practicality of the bracket.

[0022] 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.

[0023] Reference Figure 1-3This utility model provides an embodiment of an engineering surveying support, comprising a mounting base body 1 for mounting measuring equipment. Multiple rotating blocks 2 are rotatably connected to the outer periphery of the mounting base body 1. A fixed support rod 3 is bolted to the bottom of each rotating block 2, allowing the fixed support rod 3 to rotate around the outer periphery of the mounting base body 1 via the rotating blocks 2. A housing 4 is fixedly connected to the outer wall of the fixed support rod 3, and a movable support rod 6 is slidably connected to the bottom of the housing 4. The movable support rod 6 can move within the housing 4, thereby adjusting the height of the mounting base body 1. Pads 5 are provided at the bottom of the movable support rod 6 and the bottom of the fixed support rod 3. During use, the pads 5 directly contact the ground, protecting the bottom ends of the fixed support rod 3 and the movable support rod 6 and preventing damage to their bottoms. Wear occurs. The bottom ends of both the fixed support rod 3 and the movable support rod 6 are provided with slots that are adapted to the size of the insert block 8. Two insert blocks 8 are fixedly connected to the bottom of the pad block 5. By inserting the insert blocks 8 into the slots, the insert blocks 8 can be connected to the fixed support rod 3 and the movable support rod 6. The outer wall of the insert block 8 is provided with a insertion hole, and an insertion rod 10 is provided in the insertion hole. By inserting the insertion rod 10 into the insertion hole, the insert block 8 can be limited to ensure its stability in the slot, thereby preventing the pad block 5 from falling off. A rotating rod 11 is provided on the side of the two insertion rods 10 that are close to each other. The outer wall of the rotating rod 11 is fixedly connected with teeth 12. By rotating the rotating rod 11, the teeth 12 on its outer wall can be rotated, and the teeth 12 can be used to move the insert rod 10. The teeth 12 mesh with the outer wall of the insert rod 10. A moving plate 7 is sleeved on the outer wall of the rotating rod 11 that is away from the teeth 12.

[0024] Reference Figure 2-4 The movable plate 7 has a groove in its middle, and a protrusion 13 is provided in the groove. The protrusion 13 is fixedly connected to the outer wall of the rotating rod 11 at the end away from the teeth 12. When the protrusion 13 is in the groove, the movable plate 7 can limit the rotating rod 11 by limiting the protrusion 13. Two sliding rods 9 are fixedly connected to the side of the movable plate 7 near the insertion rod 10. The sliding rods 9 are slidably connected to the fixed support rod 3 or the movable support rod 6, and the movable plate 7 can be rotated by the sliding rods 9. A spring 14 is sleeved on the outer wall of the middle end of the rotating rod 11. One end of the spring 14 is connected to the movable plate 7, and the other end of the spring 14 is connected to the outer wall of the fixed support rod 3 or the movable support rod 6. The spring 14 can reset the movable plate 7, and thus the movable plate 7 can limit the protrusion 13. The insertion holes on the outer walls of the two insertion blocks 8 are located at the top and the bottom, respectively. The insertion rod 10 can be inserted into the insertion hole to limit the insertion block 8. A knob is provided on the outer wall of the housing 4, which can be used to fix the movable support rod 6.

[0025] Working principle: First, adjust the height of the mounting base body 1 according to actual usage needs. Pull the movable support rod 6 out from the bottom of the housing 4 and fix it with a knob. Then unfold the fixed support rod 3 to support the mounting base body 1. Then, place the pad 5 in contact with the ground to complete the deployment of the bracket. When the pad 5 needs to be replaced, first press the moving plate 7 and compress the spring 14 to disengage the protrusion 13 from the groove. Then rotate the rotating rod 11 to rotate the tooth 12, which in turn moves the insertion rod 10, causing the insertion rod 10 to move out of the insertion hole on the insertion block 8, thereby releasing the limitation on the insertion block 8. Then, the insertion block 8 can be pulled out for replacement. Conversely, the insertion block 8 can be installed to avoid the fixed support rod 3 and the movable support rod 6 becoming uneven in height due to excessive friction, which would cause the mounting base body 1 to tilt.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
