For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] Reference Figure 1-3 The present embodiment provides a construction auxiliary device for a clamp-type fire-fighting pipe joint, which includes: a height adjustment component 10, a pipe support 20 and a gap caliper 30. The height adjustment component 10 is arranged below the pipe support 20 and can raise and lower the pipe support 20; the gap caliper 30 is rotatably arranged on one end surface of the pipe support 20, and its rotating shaft is in the same direction as the axis of the pipe support 20.

[0029] The construction steps include: (1) arranging at least two construction auxiliary devices on the idle side of the installed pipe (i.e., the end of the next section of the pipe to be installed) to ensure that the pipe to be installed has at least two supported points. In this process, it is necessary to determine the layout direction of the construction auxiliary devices: the gap caliper 30 in the one of the multiple construction auxiliary devices closest to the installed pipe is located on the side of the pipe support 20 close to the installed pipe, and the axis of the pipe support 20 in each auxiliary device is in the same direction as the axis of the pipe to be installed; it is also necessary to determine the layout points of the construction auxiliary devices: the number and spacing of the devices are determined according to the length and quality of the pipe to be installed, and the gap caliper 30 in the one of the multiple construction auxiliary devices closest to the installed pipe is abutted against the end face of the installed pipe. (2) Place the pipe to be installed on the pipe support 20, and push the pipe to be installed toward the gap caliper 30 abutting against the end face of the installed pipe until the distance between it and the gap caliper 30 meets the construction specifications. (3) Install a clamp-type joint on the adjusted pipe to complete the construction.

[0030] The above-mentioned device is used to assist in construction, which can improve the installation accuracy of fire-fighting pipes. By arranging and adjusting the direction and position of the device in advance, compared with adjusting the axis of the fire-fighting pipe with a large supporting mass later, the operation difficulty of the workers can be greatly reduced and the adjustment accuracy can be improved; by adjusting the height of the pipe to be installed, the height of the pipe to be installed can be flexibly adjusted by adjusting the height component 10, so that the pipe can be installed quickly, the adjustment accuracy and adjustment efficiency can be improved, and quality problems such as leakage in the later stage can be prevented; the gap caliper 30 is used to control the spacing between adjacent pipe ends to make it meet the construction specifications and the specifications of the clamp-type joints used, which can prevent quality problems such as loose fixation of the clamp-type joints and leakage in the later stage.

[0031] The structure of the height-adjusting component 10 can be configured according to actual needs, and no specific restrictions are made here. The following only illustrates some of the feasible technical solutions, but it does not serve as a limitation on the technical solutions for the height-adjusting component 10 in this application. Components with lifting functions should be regarded as part or all of the components of the height-adjusting component 10 in this embodiment and included in the scope of protection of this application.

[0032] In some technical schemes, the height adjustment component 10 is configured to include a base plate 11, a supporting member 12 and a driving rod 13. The area of ​​the base plate 11 is larger than the cross-section of other components, which can improve the support stability. At the same time, the base plate 11 can be set to a regular geometric shape or markings can be set on the base plate 11, and the special points in the regular geometric shape (such as the midpoint of the edge line, etc.) or the preset markings on the base plate 11 can be made to coincide with the layout markings of the pipe to be installed (such as the axis ink line), so as to improve the adjustment efficiency of the axial direction of the pipe support 20; the supporting member 12 is block-shaped, and the top support is arranged on it. The supporting member 12 is provided with a threaded groove 12a with an opening facing the driving rod 13, and the threaded groove 12a and the driving rod 13 are both arranged in the vertical direction; the bottom end of the driving rod 13 is rotatably connected to the base plate 11, and the top end extends into the threaded groove 12a and is threadedly connected to it. The height of the supporting member 12 and the pipe support 20 can be adjusted by rotating the driving rod 13.

[0033] In order to improve the adjustment smoothness of the height adjustment component 10, the driving rod 13 in this embodiment uses a screw of ordinary specifications (because if a special large-diameter screw is set, the difficulty of rotation will be greatly increased due to its own weight, contact area and other factors), a rotating sleeve 14 is set on the outside of the driving rod 13, the driving rod 13 is fixed to the inner bottom surface of the rotating sleeve 14, and a bearing 15 is set at the bottom of the rotating sleeve 14, and the bearing 15 is used to connect the base plate 11, wherein the outer ring and the inner ring of the bearing 15 are respectively connected to the rotating sleeve 14 and the base plate 11 to achieve smooth rotation.

[0034] When the diameter of the driving rod 13 becomes smaller, its supporting force is relatively reduced, so an annular groove 12b can be set on the supporting member 12, and the depth and direction of the annular groove 12b are consistent with the thread groove 12a, that is, the opening faces the rotating sleeve 14, and the shape of the annular groove 12b is adapted to the cross-sectional shape of the rotating sleeve 14. When the driving rod 13 extends into the thread groove 12a, the rotating sleeve 14 is inserted into the annular groove 12b with equal depth, and the friction between the rotating sleeve 14 and the annular groove 12b improves the supporting stability of the supporting member 12. Compared with the solution of directly configuring a special large-diameter screw, the rotation smoothness of this solution is greatly improved under the premise of ensuring the supporting force required by the supporting member 12. In order to facilitate the rotation operation, a gripping handle or convex pattern (not shown in the drawings) can be set on the outer wall of the rotating sleeve 14.

[0035] When the driving rod 13 rotates, it will generate friction on the supporting member 12. Since the fire-fighting pipe has a large deadweight, when it is pressed on the pipe support 20, the tendency of the supporting member 12 to rotate around the driving rod 13 can be eliminated. In most construction specifications, it can meet the pipe axis docking tolerance. However, if it is desired to further improve the accuracy of the pipe axis docking, a limit slide bar 16 can be set on the bottom plate 11. The limit slide bar 16 extends in the same direction as the driving rod 13. A slide groove 12c with an opening facing the limit slide bar 16 is set on the supporting member 12, and the limit slide bar 16 is slid through the slide groove 12c. On the one hand, the supporting member 12 cannot rotate due to the limit of the limit slide bar 16 and the driving rod 13. On the other hand, the friction between the limit slide bar 16 and the slide groove 12c can also improve the support stability.

[0036] The number and position of the above-mentioned limiting slide rods 16 can be configured according to actual needs. Preferably, at least two of them are configured and evenly distributed around the outer circumference of the rotating sleeve 14 so that the force generated by them on the supporting member 12 is symmetrically distributed (axially symmetrical or centrally symmetrical), thereby improving the stability and smoothness of movement of the supporting member 12.

[0037] Reference Figure 1 and 4 The pipe support 20 is in an arc-shaped plate shape, and an insert ring 40 is provided on the pipe support 20. One end of the gap caliper 30 is provided on an insert rod 50 adapted to the insert ring 40, and the insert rod 50 is rotatably inserted in the insert ring 40. The width of the gap caliper 30 can be configured according to different construction standards and usage requirements, and can also be standardized and manufactured in various specifications, and replaced according to actual needs.

[0038] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging and adjusting the direction and position of the device in advance, the difficulty of operation for workers can be greatly reduced and the adjustment accuracy can be improved compared to adjusting the axis of the fire-fighting pipe with a large supporting mass later; by flexibly adjusting the height of the pipe to be installed by adjusting the height component 10, the pipe can be quickly installed, the adjustment accuracy and efficiency can be improved, and quality problems such as leakage in the later stage can be prevented; the gap caliper 30 is used to control the spacing between adjacent pipe ends to make it comply with the construction specifications and the specifications of the clamp-type joints used, which can prevent quality problems such as loose fixation of the clamp-type joints and leakage in the later stage.

[0039] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
