Description

Technical Field

[0001] The utility model belongs to the technical field of building tools, and in particular relates to a pipeline pre-buried device for building construction which has the advantages of simple structure, convenient adjustment and high reliability. Background Art

[0002] Pre-buried pipes refer to pipes that are pre-buried in construction projects for subsequent structural and process construction to facilitate subsequent wiring. During the process of pre-buried pipes, the pipes need to be fixed and positioned to avoid deviations during pre-buried pipes, which would affect the correct laying of subsequent pipes.

[0003] At present, pipe clamps are generally used to fix and position pipelines, and the pipe clamps are fixed to the foundation or other foundations by expansion screws. Although the pipe clamp fixing structure is simple, low-cost and convenient to construct, the clamping force of the pipe clamp on the pipeline is difficult to control, which may easily cause the pipeline to loosen after fixation or clamp too tightly to cause pipeline damage. In addition, the expansion screw fixing structure may easily damage the foundation, and it is difficult to remove the expansion screws after the pipeline is fixed, which may easily affect subsequent construction.

[0004] In the prior art, in order to solve the problem of positioning and fixing the embedded pipe, a shock-absorbing sleeve and a storage pipe are fixedly connected to the upper surface of the base plate respectively, the inner wall of the shock-absorbing sleeve is slidably connected to a placement platform, the top end of the storage pipe is rotatably connected to a fixing nut, the inner wall of the fixing nut is threadedly connected to a fixed threaded rod, and the top end of the fixed threaded rod is fixedly connected to an arc-shaped pipe clamp, so that the fixed threaded rod can be moved up and down by adjusting the fixing nut, so that the placement platform and the arc-shaped pipe clamp form a pipe clamping mechanism; then, a ground nail is fixedly connected to the lower surface of the base plate, and a strut mechanism is arranged between the base plate and the ground nail, so that the foundation is inserted through the ground nail, and the strut mechanism is adjusted to fix the ground nail firmly on the foundation; not only can the clamping force of the pipe be adjusted by adjusting the fixing nut, but the cooperation of the ground nail and the strut mechanism can not only fix the entire device, but also facilitate removal after the pipe is fixed without affecting subsequent construction; however, the ground nail and the strut mechanism will still damage the foundation. Of course, there are also methods in the prior art that two symmetrical fixing plates are fixedly installed on the upper end of the fixing plate, and threaded rotating rods are fixedly installed on the upper ends of the two fixing plates, and the middle parts of the two threaded rotating rods are threadedly connected to the connecting circular plate, and the two connecting circular plates are movably connected with the connecting ring tube, and the opposite side walls of the two connecting ring tubes are fixedly installed with fixed clamping plates; thereby rotating the two threaded rotating rods respectively to make them move toward each other, the threaded rotating rods drive the connecting circular plate to rotate and drive the two fixed clamping plates to move toward each other through the connecting ring tube, and finally stably clamp the circular pipe in the middle to fix and position it; although the device will not damage the foundation, the two threaded rotating rods can also be controlled to adjust the appropriate clamping force. However, the aforementioned pipeline pre-buried devices do not have the function of adjusting the direction of the pipeline, so when the direction of the pipeline is changed, the pre-buried structure with a fixed direction is not conducive to adjusting the angle of the pipeline; at the same time, for a relatively harsh construction environment, soil and rocks are also easy to fall into the thread pair, which is not only not conducive to the operator turning the thread pair to adjust the clamping force, but also the labor intensity of manually turning the threaded rotating rod is relatively high.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention belong to the protection scope of the present invention.

[0028] like Figures 1 to 4 As shown, the utility model includes a sliding seat 1, a tooth seat 2, a ratchet mechanism 3, an annular seat 4, and a base 5. The tooth seat 2 is a cylindrical structure and a plurality of tooth grooves 21 are arranged at intervals on the outer circumference. The top surface of the tooth seat 2 is fixedly connected to the bottom surface of the sliding seat 1. The annular seat 4 is arranged below the sliding seat 1. The tooth seat 2 movably extends into the annular cavity of the annular seat 4. A notch 41 is opened on one side of the annular cavity of the annular seat 4.

[0029] The ratchet mechanism 3 includes a check plate 31 and a spring 32. The spring 32 is arranged in the notch 41. One end of the check plate 31 extends into the notch 41 and is hinged to the annular seat 4, and the other end extends into the annular cavity and engages with the tooth groove 21. The two ends of the spring 32 are fixedly connected to the inner wall of the notch 41 and the check plate 31 respectively.

[0030] The base 5 is arranged below the sliding seat 1 , the annular seat 4 is fixedly connected to the base 5 , and a clamping mechanism 6 capable of clamping a pipe is connected above the sliding seat 1 .

[0031] An annular groove 51 is formed at the upper end of the base 5 , and the annular seat 4 is detachably fixedly embedded in the annular groove 51 .

[0032] The clamping mechanism 6 includes an electric control box 61 and an arc-shaped clamping plate 63. The two electric control boxes 61 are respectively fixedly arranged on the opposite side surfaces of the sliding seat 1. An automatic linear unit 62 is arranged in the electric control box 61. The driving shaft of the automatic linear unit 62 movably penetrates the side wall of the electric control box 61 and extends to the other side of the electric control box 61. The arc-shaped clamping plate 63 is arranged above the sliding seat 1 and is fixedly connected to the top end of the driving shaft of the automatic linear unit 62.

[0033] It should be noted that the clamping mechanism 6 of the utility model can also be an electric control box 61 fixedly arranged on one side of the sliding seat 1, and a fixed seat is fixedly arranged on the other side of the sliding seat 1 relative to the electric control box 61, and an arc-shaped clamping plate 63 is also fixedly arranged on the side of the fixed seat facing the electric control box 61, and an automatic linear unit 62 is arranged in the electric control box 61, and an arc-shaped clamping plate 63 fixedly connected to the driving shaft of the automatic linear unit 62 is arranged on the side of the electric control box 61 facing the fixed seat.

[0034] The automatic linear unit 62 is a cylinder, a hydraulic cylinder or a linear motor.

[0035] A telescopic rod 64 is also fixedly arranged inside the electric control box 61. The telescopic end of the telescopic rod 64 is parallel to the driving shaft of the automatic linear unit 62. The telescopic end of the telescopic rod 64 movably penetrates through the side wall of the electric control box 61 and is fixedly connected to the arc-shaped clamping plate 63. The telescopic rod 64 can not only disperse the force application points of the arc-shaped clamping plate 63, thereby reducing the force on the driving shaft of the automatic linear unit 62, but also form a double support with the driving shaft of the automatic linear unit 62, and can also prevent the arc-shaped clamping plate 63 from tipping over when the force is uneven and the driving shaft of the automatic linear unit 62 from getting stuck.

[0036] Side arc plates 65 are fixedly arranged on the opposite surfaces of the electric control box 61. The arc-shaped clamping plate 63 is arranged on the inner side of the side arc plate 65 away from the electric control box 61. The side arc plate 65 is also provided with a through hole Ⅰ through which the telescopic end of the telescopic rod 64 and the driving shaft of the automatic linear unit 62 can movably pass.

[0037] An arc groove 66 is formed on the inner arc surface of the side arc plate 65. The arc-shaped clamping plate 63 can be movably embedded into the arc groove 66. The arc groove 66 can protect the arc-shaped clamping plate 63 embedded therein and prevent the arc-shaped clamping plate 63 from being damaged by collision during the handling of the embedded device.

[0038] Anti-slip lines are arranged on the inner side surface of the arc-shaped clamping plate 63 away from the electric control box 61, or an anti-slip and shock-absorbing rubber pad is fixed. The anti-slip lines and the anti-slip and shock-absorbing rubber pad can increase the friction between the arc-shaped clamping plate 63 and the pipeline during clamping, so as to ensure stable clamping of the pipeline with a smaller clamping force and avoid damage to the pipeline caused by excessive clamping force; and the anti-slip and shock-absorbing rubber pad can also reduce the vibration of the pipeline after fixation, so that the pipeline is not easily damaged or displaced due to vibrations such as pouring concrete after clamping.

[0039] An arc groove 11 parallel to the axis of the arc-shaped clamping plate 63 is formed on the top surface of the sliding seat 1.

[0040] Lug plates 7 are fixedly arranged at the top end of the electric control box 61. A shielding cover plate 8 is detachably connected between the lug plates 7 of the two electric control boxes 61 above the moving range of the arc-shaped clamping plate 63.

[0041] The shielding cover plate 8 is of a "C" - shaped or inverted "凵" - shaped structure and has screw holes at both ends. The lug plate 7 is provided with a through hole Ⅱ. The lug plate 7 and the shielding cover plate 8 are fixedly connected by screws 9 passing through the through hole Ⅱ and the screw holes. After the pipeline is installed, the operator uses tools to loosen the screw 9 on one side of the lug plate 7, so that the shielding cover plate 8 rotates to the top of the pipeline for shielding, and then tightens the screw 9 to fix the shielding cover plate 8, which can prevent the soil, gravel, etc. from sinking and colliding with the pipeline after burial, causing external wear of the pipeline.

[0042] A control system and a storage battery are also arranged inside the electric control box 61. The control system and the storage battery are respectively electrically connected to the automatic linear unit 62.

[0043] The working principle and working process of this utility model:

[0044] like Figures 1 to 4 As shown, when the direction of the pipeline needs to be fine-tuned, the operator pushes the sliding seat 1 counterclockwise to drive the tooth seat 2 to rotate in the annular seat 4 of the base 5. The non-return plate 31 in the annular seat 4 is pressed toward the spring 32, so that the sliding seat 1 can rotate counterclockwise. When the sliding seat 1 stops rotating, the spring 32 resets and drives the non-return plate 31 to engage in the tooth groove 21 of the tooth seat 2, so as to adjust the direction of the pipeline and facilitate the multi-angle rotation and burial of the pipeline. If the operator pushes the sliding seat 1 clockwise, the non-return plate 31 is blocked by the tooth groove 21 and the sliding seat 1 cannot rotate, which can prevent the sliding seat 1 from being accidentally stressed and causing the pipeline direction to change.

[0045] When positioning the pipeline, the pipeline is placed on the arc groove 11 of the sliding seat 1 through a crane, and the operator controls the electric control box 61 on both sides of the sliding seat 1 to start the hydraulic cylinder (i.e., the automatic linear unit 62). The piston rod of the hydraulic cylinder pushes the arc clamping plate 63 out of the side arc plate 65 and engages with the outside of the pipeline to fix the pipeline; when the pipeline is pre-buried, the operator uses a tool to loosen the screw 9 on one side of the ear plate 7, so that the baffle plate 8 rotates to the top of the pipeline for covering, and then tightens the screw 9 to fix the baffle plate 8, which can prevent the soil, gravel, etc. from sinking and colliding with the pipeline after burial, causing wear on the outside of the pipeline.

[0046] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
