[0002] The inclinometer tube lowering and fixing device is an important device used for installing inclinometer tubes in underground projects. Its main function is to ensure that the inclinometer tube can be accurately and stably embedded underground and maintain its position and direction unchanged. However, when loosening the arc-shaped clamp of the direct tube during installation, if the inclinometer tube is not firmly grasped, the inclinometer tube will slide down rapidly, causing the inclinometer tube to directly enter the drilled hole. After increasing the working force to take out the inclinometer tube, the laying of the inclinometer tube can continue. Content of the Utility Model

[0003] The purpose of the utility model is to provide an inclinometer tube lowering and fixing device to solve the problem that when loosening the arc-shaped clamp of the direct tube during installation, if the inclinometer tube is not firmly grasped, the inclinometer tube will slide down rapidly as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an inclinometer tube lowering and fixing device, including a fixed sleeve a and an arc-shaped clamp installed inside the fixed sleeve a;

[0005] The outer walls of the front, rear, left, and right ends of the fixed sleeve a are all drivingly connected with adjusting knobs to control the moving direction of the arc-shaped clamp;

[0006] A plurality of sliding sleeves are arranged on the lower side of the fixed sleeve a to support the subsequent placement position of the fixed sleeve a;

[0007] An adjusting screw is arranged between the adjusting knob and the arc-shaped clamp, and a positioning shaft is fixedly connected between the left end outer wall of the adjusting screw and the arc-shaped clamp to limit the position of the arc-shaped clamp;

[0008] The lower end outer wall of the arc-shaped clamp is fixedly connected with an extension block, and a baffle is drivingly connected inside the extension block to limit the position of the direct tube on the inclinometer tube. A spring is arranged inside the baffle, and a limiting plate fixedly connected to the upper end inner wall of the extension block and penetrating downward into the baffle is used to limit the position of the spring.

[0009] Preferably, an upward-opening groove is formed inside the baffle to limit the installation position of the spring, and a positioning rod penetrating inside the spring is fixedly connected to the front end outer wall of the limiting plate to limit the contraction direction of the spring.

[0010] Preferably, a limiting block clamped inside the baffle is fixedly connected to the lower end outer wall of the arc-shaped clamp to limit the moving direction of the baffle, and a limiting sliding rod is fixedly connected to the lower end outer wall of the baffle to drive the baffle to move under an external force.

[0011] Preferably, one baffle is provided and is arranged on the lower side of one of the plurality of arc-shaped jigs, and there is no contact between the outer wall of the lower end of the extension block and the inner wall of the lower end of the groove.

[0017] By installing the baffle, the extension block, the spring and the limiting plate, when the arc-shaped jig clamps the inclinometer pipe, the baffle abuts against the circular outer wall surface of the inclinometer pipe under the pressure of the spring. When the arc-shaped jig becomes loose after installing the straight pipe, the baffle still contacts the circular outer wall surface of the inclinometer pipe under the pressure of the spring. And during the downward sliding process of the inclinometer pipe, the baffle will lift the straight pipe connected between the two inclinometer pipes, avoiding the situation that the inclinometer pipe continues to slide down, thus avoiding the situation that the inclinometer pipe slides into the drilled hole, avoiding increasing the working difficulty and the situation that it takes a lot of time to take out the inclinometer pipe, and ensuring the stability during the lowering of the conveyed inclinometer pipe.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The present utility model provides a device for lowering and fixing an inclinometer tube as shown in Figures 1-3 which includes a fixed sleeve a3 and an arc-shaped clamp 1 installed inside the fixed sleeve a3;

[0026] The outer walls of the four ends of the fixed sleeve a3 in the front, back, left, and right directions are all drivingly connected with adjusting knobs 2 to control the moving direction of the arc-shaped clamp 1;

[0027] A plurality of sliding sleeves 7 are arranged on the lower side of the fixed sleeve a3 to support the subsequent placement position of the fixed sleeve a3;

[0028] An adjusting screw 11 is arranged between the adjusting knob 2 and the arc-shaped clamp 1. A positioning shaft 12 is fixedly connected between the outer wall of the left end of the adjusting screw 11 and the arc-shaped clamp 1 to limit the position of the arc-shaped clamp 1. The center of the fixed sleeve a3 is supported directly above the drilling position through the sliding sleeve 7. Subsequently, when lowering the inclinometer tube, the inclinometer tube is lowered from the center of the arc-shaped clamp 1. When manually lowering it to the end, hold the inclinometer tube, and then rotate the adjusting knob 2 clockwise. During the process of restricting the rotation of the adjusting screw 11, the positioning shaft 12 will not drive the arc-shaped clamp 1 to rotate, so that the adjusting screw 11 rotates and pushes the arc-shaped clamp 1 to fit the circular outer wall surface of the inclinometer tube. Then, a straight tube can be put on, and another inclinometer tube is sleeved on the straight tube. Subsequently, rotate the adjusting knob 2 counterclockwise, so that the adjusting screw 11 drives the arc-shaped clamp 1 to move away from the inclinometer tube and the straight tube and make a slight contact to maintain a certain resistance. At this time, the inclinometer tube can be kept automatically lowered slowly, reducing the labor intensity of the staff;

[0029] An extension block 16 is fixedly connected to the outer wall of the lower end of the arc clamp 1, and the internal transmission connection of the extension block 16 is connected to a baffle 14 to limit the position of the direct pipe on the inclinometer tube. A spring 13 is provided inside the baffle 14, and a limit plate 17 is fixedly connected to the inner wall of the upper end of the extension block 16, which penetrates downwardly into the inside of the baffle 14 to limit the position of the spring 13. After installing the direct pipe, when the arc clamp 1 is released to lower the direct pipe, if the inclinometer tube slips out of the hand and slides downward, the baffle 14 can lift the direct pipe whose width is greater than the inclinometer tube, thereby limiting the position of the direct pipe and preventing the inclinometer tube from continuing to slide down and sliding into the borehole. When the inclinometer tube is slowly lowered, the baffle 14 can increase the friction between it and the surface of the inclinometer tube, slowing down the speed at which the inclinometer tube automatically slides down.

[0030] like Figure 4 and Figure 5 As shown, an upwardly opening groove 19 is provided inside the baffle 14 to limit the installation position of the spring 13, and the front end outer wall of the limit plate 17 is fixedly connected to a positioning rod 20 running through the inside of the spring 13 to limit the contraction direction of the spring 13. The lower end outer wall of the arc clamp 1 is fixedly connected to a limit block 18 clamped inside the baffle 14 to limit the moving direction of the baffle 14, and the lower end outer wall of the baffle 14 is fixedly connected to a limiting slide rod 15 to drive the baffle 14 to move under the action of external force.

[0031] When the spring 13 pushes the baffle 14 to abut the surface of the inclinometer tube, the limit plate 17 limits the spring 13 to a contracted state to push the baffle 14 to abut the surface of the inclinometer tube, and when the spring 13 contracts, the positioning rod 20 limits the contraction direction of the spring 13 to prevent the spring 13 from popping out of the groove 19. When the direct tube is lowered, the staff can manually hold the limit slide 15 and drive the baffle 14 to move the position so that the direct tube can be lowered through the baffle 14. When the direct tube is moved out of the fixed sleeve a3, the limit slide 15 can be released, and the baffle 14 can fit the surface of the inclinometer tube again.

[0032] like Figure 2 and Figure 5 As shown, a baffle 14 is provided and is arranged on the lower side of one of the multiple arc-shaped clamps 1, and the outer wall of the lower end of the extension block 16 and the inner wall of the lower end of the groove 19 are not in contact.

[0033] A single baffle 14 can prevent multiple baffles 14 from restricting the position of the direct pipe at the same time, increasing the complexity of subsequent staff adjusting the position of the baffle 14, and speeding up the speed of allowing the direct pipe to pass after being restricted by the baffle 14. There is no contact between the outer wall of the lower end of the extension block 16 and the inner wall of the lower end of the groove 19, which avoids the situation where the extension block 16 restricts the movement of the baffle 14 when the baffle 14 moves.

[0034] like Figure 1As shown, a fixing sleeve b5 is fixedly connected to the outer wall of the lower end of the fixing sleeve a3. Fixing blocks 4 are fixedly connected to the outer walls of the front, rear, left, and right ends of the fixing sleeve b5. The other sides of the plurality of fixing blocks 4 are all drivingly connected to fixing shafts 6 to fixedly connect to the sliding sleeves 7 to limit the tilting angle of the sliding sleeves 7. The inner part of the outer wall of the lower ends of the plurality of sliding sleeves 7 is slidably connected to a support leg 9.

[0035] When adjusting the stability of the fixing sleeve a3, the support leg 9 can be pulled out from the inside of the sliding sleeve 7, and the pulling length of the support leg 9 can be controlled according to the tilting angle of different ground surfaces. Moreover, the angle between the sliding sleeve 7 and the support leg 9 can be adjusted through the fixing shaft 6 to more quickly adjust the position of the fixing sleeve a3. After the support leg 9 is pulled out, the support leg 9 can be fixed through the fixing buckle at the lower end of the sliding sleeve 7.

[0036] As Figure 1 shown, weight-reducing grooves 8 are provided inside the plurality of sliding sleeves 7 and support legs 9 to reduce the weights of the sliding sleeves 7 and support legs 9. Four arc-shaped clamps 1 are provided. A plurality of limiting rods 10 are fixedly connected between the arc-shaped clamps 1 and the fixing sleeve a3 to limit the arc-shaped clamps 1 to be on the same horizontal plane during movement. A through port for the limiting rods 10 to move is provided inside the fixing sleeve a3.

[0037] The provision of a plurality of arc-shaped clamps 1 can clamp and limit the surface of the inclinometer tube at more angles. Moreover, when the adjusting knob 2 adjusts the movement of the arc-shaped clamps 1, the arc-shaped clamps 1 can be kept moving on the same horizontal plane through the limiting rods 10.

[0038] The implementation principle of this embodiment is as follows: The center of the fixed sleeve a3 is supported directly above the drilling position through the sliding sleeve 7. Subsequently, when lowering the inclinometer tube, the inclinometer tube is lowered from the center of the arc-shaped fixture 1. When manually lowering it to a certain length at the end, hold the inclinometer tube by hand. Then, rotate the adjustment knob 2 clockwise. During the process of restricting the rotation of the adjustment screw 11, the positioning shaft 12 will not drive the arc-shaped fixture 1 to rotate, causing the adjustment screw 11 to rotate and push the arc-shaped fixture 1 to fit the circular outer wall surface of the inclinometer tube. Then, the straight tube can be put on, and another inclinometer tube is sleeved on the straight tube. Subsequently, rotate the adjustment knob 2 counterclockwise, causing the adjustment screw 11 to drive the arc-shaped fixture 1 away from the inclinometer tube and the straight tube and make a slight contact to maintain a certain resistance. At this time, the inclinometer tube can be automatically and slowly lowered, reducing the labor intensity of the staff. When the straight tube is loosened below the arc-shaped fixture 1 after installing the straight tube and there is a situation of loosening and slipping out of the hand, the baffle 14 can support the straight tube, thereby restricting the position of the straight tube and preventing the situation of continuous sliding and slipping into the drilling hole. When the inclinometer tube is slowly lowered, the baffle 14 can increase the friction force between the baffle 14 and the surface of the inclinometer tube, slowing down the automatic sliding speed of the inclinometer tube. When lowering the straight tube, the staff can manually hold the limit slide bar 15 and drive the baffle 14 to move its position, so that the straight tube can be lowered through the baffle 14. When the straight tube is removed from the inside of the fixed sleeve a3, the limit slide bar 15 can be released. At this time, the baffle 14 fits the surface of the inclinometer tube again.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
