Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to a bracket for assembling and constructing mechanical and electrical pipelines in buildings. Background Art

[0002] During the construction process, it is necessary to set up a construction frame outside the main construction body, and workers use the construction frame to carry out construction work. Mechanical and electrical pipelines are often needed during construction work, and it is necessary to arrange the mechanical and electrical pipelines to facilitate construction. In order to reasonably arrange the pipelines in a limited space, pipeline brackets are used in the construction area of large buildings to complete the installation of various pipelines. Existing pipeline assembly brackets often use a relatively large scaffolding form. During the construction process, it is often inconvenient for construction workers to fix or install building pipelines. Moreover, the single-structure scaffolding form has poor applicability. Specifically, when a unified pipeline assembly bracket is used for fixing, it is often unable to meet the installation requirements of pipelines of different diameters due to the different diameters of the pipelines. The installation is time-consuming and labor-intensive. Therefore, the previous single-structure pipeline brackets have the problems of single structure, inconvenience in use, and poor applicability.

DETAILED DESCRIPTION

[0036] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1 FIG. 1 is a structural diagram of a support for assembling and constructing mechanical and electrical pipelines provided by an embodiment of the present invention. Specifically, in a preferred embodiment provided by the present invention, the support includes:

[0038] The crossbeam 100 has a mounting slot 101 at the bottom;

[0039] A support frame 200 is provided with a mounting base 201 at the top of the support frame 200. The mounting base 201 is vertically inserted into the mounting groove 101 and fixed by the mounting structure;

[0040] The crossbar frame is height-adjustably mounted on the support frame 200 via a first lifting assembly;

[0041] A buffer support member for supporting and installing the top seat 201 is height-adjustably mounted on the support stand 200 via a second lifting assembly and is located below the crossbar frame;

[0042] The fixing mechanism 300 is used to clamp and fix the pipeline. The fixing mechanism 300 is installed on the cross bar frame through a locking assembly. The fixing mechanism 300 includes a fixing seat 301 installed on the cross bar frame through a locking assembly and a support bracket 307 for supporting the pipeline. The support bracket 307 is fixed on both sides of the fixing seat 301.

[0043] By moving the crossbar frame upward through the first lifting assembly and the buffer support member upward through the second lifting assembly, the pipeline installed on the fixing mechanism 300 can be lifted in height, that is, the fixed pipeline can be raised to a position at a specified height. When the downward displacement of the buffer support member is less than the vertical downward displacement of the crossbar frame, the buffer support member provides buffering support for the crossbar frame, which is not only suitable for the installation and fixation of the pipeline, but also can lift the installed pipeline to a specified height, and is safe, reliable and practical.

[0044] Furthermore, in a preferred embodiment provided by the present invention, the cross bar frame includes a first frame body 500 and a second frame body 600 opposite to each other in the upper and lower directions, each first frame body 500 is equipped with at least two sets of fixing mechanisms 300, and each second frame body 600 is equipped with at least two sets of fixing mechanisms 300. By arranging the first frame body 500 and the second frame body 600 opposite to each other in the upper and lower directions, different pipelines can be fixed, thereby avoiding the pipelines from being entangled at the same height.

[0045] See also Figure 1 and Figure 4 In an embodiment of the present invention, the first lifting assembly includes a vertical screw rod 208 rotatably arranged on the supporting frame 200 and a retractable disk 209 coaxially fixedly installed on the vertical screw rod 208, and the retractable disk 209 is wound in the same direction with a first rigid rope 210 and a second rigid rope 211 respectively connected to the cross bar frames on both sides of the supporting frame 200, wherein the free end of the first rigid rope 210 is connected to the first frame body 500, and the free end of the second rigid rope 211 is connected to the second frame body 600.

[0046] Please continue reading Figure 1-3In the preferred embodiment provided by the present invention, the second lifting assembly includes a lifting plate 704 and a buffer spring 705 connecting the lifting plate 704 and the buffer support member, the buffer support member includes a first buffer member 700 located below the first frame 500 and a second buffer member 800 located below the second frame 600, the first buffer member 700 and the second buffer member 800 both include a buffer support cylinder 701 sleeved on the vertical screw rod 208 by a threaded connection. Therefore, according to the rotation direction of the vertical screw rod 208, the height position of the buffer support cylinder 701 can be adjusted, that is, the height of the buffer support member can be adjusted; the lifting plate 704 is fixedly installed below the buffer support cylinder 701, and a sliding sleeve is provided on the buffer support cylinder 701 There is a buffer support slider 702, which is connected to the lifting plate 704 through a buffer spring 705. The outer ring of the buffer support slider 702 also has multiple buffer support protrusions 703. A certain distance is left between the buffer support cylinder 701 and the lifting plate 704. The buffer spring 705 is set in this reserved distance, which can give the buffer spring 705 enough space to deform. First, the vertical screw rod 208 rotates to drive the retractable disk 209 to rotate. The first rigid rope 210 and the second rigid rope 211 are respectively connected to the cross bar frame on both sides. When the retractable disk 209 rotates, the first rigid rope 210 and the second rigid rope 211 drive the cross bar frame to move up and down, and the buffer support protrusion 703 can effectively play a buffering and supporting role on the cross bar frame.

[0047] Specifically, such as Figure 1 and Figure 5 As shown, in the preferred embodiment provided by the present invention, at least two installation channels 102 are further provided on the crossbeam 100 , and the two installation channels 102 are respectively provided on both sides of the installation groove 101 .

[0048] Wherein, the mounting structure includes:

[0049] The horizontal screw rod 204 provided on the mounting base 201 and the rectangular mounting rod 202 adapted to the mounting channel 102 are rotated, and the horizontal screw rod 204 is linked with the vertical screw rod 208. The mounting base 201 is provided with an accommodating channel 205, and the end of the horizontal screw rod 204 extends into the accommodating channel 205.

[0050] One end of the rectangular mounting rod 202 extends through the accommodating channel 205 . A thread groove 203 is formed at one end of the rectangular mounting rod 202 . The rectangular mounting rod 202 is threadedly connected to the corresponding transverse screw rod 204 through the thread groove 203 .

[0051] Please continue reading Figure 1 and Figure 5In the preferred embodiment provided by the present invention, a limiting slide groove 206 is provided on the inner wall of the accommodating channel 205, and a limiting slider 207 adapted to the limiting slide groove 206 is fixedly installed on the rectangular mounting rod 202. The limiting slider 207 is slidably arranged in the limiting slide groove 206. Therefore, in the process of the rectangular mounting rod 202 extending into and out of the accommodating channel 205, the rectangular mounting rod 202 is prevented from rotating. In this way, when the transverse screw rod 204 rotates, the rectangular mounting rod 202 can be extended from the accommodating channel 205, and the end of the rectangular mounting rod 202 can be further extended into the corresponding mounting channel 102, thereby achieving the effect of installing the mounting top 201 on the mounting groove 101.

[0052] like Figure 1 、 Figure 6 and Figure 7 As shown, in the preferred embodiment provided by the present invention, the fixing mechanism 300 includes:

[0053] The fixing base 301 is fixedly mounted on the corresponding crossbar frame. The fixing base 301 has a V-shaped groove 309. A support column 310 is provided along the bottom of the V-shaped groove 309.

[0054] The support bracket 307 for supporting the pipeline 400 is integrally formed and arranged at the top of the support column 310. The support column 310 is arranged along the bottom of the V-shaped groove 309. Both sides of the support bracket 307 are hingedly connected with fixed clamping rods 308. The arc-shaped convex surface of the fixed clamping rod 308 rests on the inclined surface of the V-shaped groove 309. When the support bracket 307 moves down to the target height, the support column 310 is locked and fixed by the locking assembly installed on the cross bar frame.

[0055] Please continue reading Figure 6-7 In the preferred embodiment provided by the present invention, an elastic cavity 302 is opened on the fixed seat 301, and a rectangular block 306 is slidably provided in the elastic cavity 302. The rectangular block 306 is supported and connected in the elastic cavity 302 by a connecting spring 304, and the end of the fixed clamping rod 308 is connected to the fixed seat 301 by an elastic connecting member; specifically, the elastic connecting member includes a connecting rope 303, one end of the connecting rope 303 is connected to the fixed clamping rod 308, and the other end of the connecting rope 303 is connected to the rectangular block 306. The fixed seat 301 also has a guide wheel 305 for guiding the connecting rope 303.

[0056] By connecting the connecting rope 303 and the fixing clamp rod 308, when a pipeline with a large diameter needs to be fixed, since the connecting rope 303 is connected to the rectangular block 306 sliding in the elastic cavity 302, the pipeline will stretch the fixing clamp rod 308, thereby achieving the effect of fixing pipelines of different diameters.

[0057] Please continue reading Figure 6-7Preferably, a through channel 501 corresponding to the support column 310 is opened on the first frame 500, and the support column 310 passing through the through channel 501 is fixed by a locking assembly.

[0058] Furthermore, the locking assembly includes a locking slider 503 supported by a locking spring 505 and arranged on the first frame 500, and a locking block 502 is fixedly installed on the locking slider 503. Under the elastic support of the locking spring 505, the locking block 502 extends into the through channel 501, and a locking lever 504 is also fixedly arranged on the locking slider 503; a plurality of locking grooves 311 are evenly distributed on one side of the support column 310, and the locking grooves 311 are adapted to the locking block 502.

[0059] It can be understood that in the embodiment of the present invention, in the process of clamping and fixing the pipeline 400, the pipeline 400 is placed on the support bracket 307, and then the pipeline 400 is continued to move downward to press the support bracket 307. The support column 310 that moves down a certain distance is fixed by the locking assembly. At the same time, the downward-moving support bracket 307 causes the two fixed clamping rods 308 to close together to clamp and fix the pipeline 400; the embodiment of the present invention provides multiple locking grooves 311, which can make the support column 310 move down to a predetermined height position as needed, so that the closing angle between the two fixed clamping rods 308 is the required angle to meet the needs of clamping and fixing pipelines 400 of different diameters.

[0060] Specifically, the locking block 502 has an inclined surface, and the downward-moving support column 310 rests on the inclined surface of the locking block 502, which can cause the locking block 502 to retract. When the locking block 502 is aligned with the locking groove 311, the locking block 502 extends to be embedded in the corresponding locking groove 311, thereby completing the locking and fixing of the support column 310.

[0061] It can be understood that in an embodiment of the present invention, the vertical screw rod 208 is driven to rotate by a driving member, and the rotating vertical screw rod 208 drives the horizontal screw rod 204 to rotate synchronously. The driving member can be a forward and reverse servo motor 900, and the forward and reverse servo motor 900 has a first shaft and a second shaft. The first shaft and the horizontal screw rod 204 are connected by gear meshing, and the second shaft is driven and connected to the vertical screw rod 208.

[0062] In another preferred embodiment of the present invention, the driving member can also be an operating handle, which can be installed on the horizontal screw rod 204 or on the vertical screw rod 208. At this time, the horizontal screw rod 204 and the vertical screw rod 208 are connected by gear meshing. Regardless of whether the vertical screw rod 208 or the horizontal screw rod 204 is rotated, the synchronous operation of the first lifting assembly, the second lifting assembly and the mounting structure can be achieved.

[0063] In the embodiment of the present invention, according to the rotation angle of the vertical screw rod 208, the first lifting assembly causes the first frame 500 and the second frame 600 to move upward synchronously, and the second lifting assembly causes the first buffer 700 and the second buffer 800 to move upward synchronously, that is, the pipeline 400 installed on the fixing mechanism 300 can be lifted in height, that is, the fixed pipeline 400 is lifted to a position at a specified height; during the lifting process, the rectangular mounting rod 202 continues to extend further into the mounting channel 102; on the contrary, it is necessary to Only when the pipeline 400 moves down to a specified height will the rectangular mounting rod 202 be completely disengaged from the mounting channel 102, that is, the mounting top seat 201 and the crossbeam 100 can always maintain a stable connection when the pipeline 400 is not moved down to the lowest point; in addition, when the first rigid rope 210 is disconnected, the first frame 500 that falls accidentally can be effectively buffered by the first buffer member 700; similarly, when the second rigid rope 211 is disconnected, the second frame 600 can be effectively buffered by the second buffer member 800.

For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0065] In the description of the present invention, it should be understood that the terms "upper", "lower", "vertical", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
