Description

Technical Field

[0001] The invention relates to the technical field of building construction auxiliary equipment, and in particular to a pipeline pre-assembly workbench. Background Art

[0002] In the design of water supply and drainage pipes in high-rise buildings and super high-rise buildings, each drainage system has several rainwater and sewage drainage pipe energy unloading devices. If the installation work cannot be completed within the lifting cycle of the overall lifting scaffolding, it will be necessary to use a hanging basket for high-altitude work in the later stage, which will increase the construction difficulty and safety risks.

[0003] The sewage pipe includes a curved pipe section, which needs to be pre-assembled to improve the installation efficiency of the drainage pipe. In the prior art, the pre-assembly of the curved pipe section is generally carried out on the ground, specifically: Figure 1 , 2 The curved pipe section shown in the figure generally includes a front section 9 and a rear section 10, both of which are provided with elbows. After the two elbows are butted together, they are bonded together with adhesive and left to stand for a period of time to complete the pre-assembly.

[0004] However, when docking on the ground, the two elbows may be misaligned, and it is not convenient to position and keep them still, so it is easy to cause misalignment of the elbow docking, which brings inconvenience to the later installation (misalignment will cause the front and rear sections to not be on the same vertical plane, and the overall drainage pipe will tilt after installation. Since the length of the drainage pipe is generally equivalent to the floor height, a small misalignment will also cause the drainage pipe to tilt to a large extent, seriously affecting safety. In severe cases, it needs to be disassembled and reinstalled). Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a pipeline pre-assembly workbench, which solves the problem in the prior art that pre-assembly on the ground easily leads to misalignment of the front section and the rear section.

[0028] like Figure 1 , 2As shown, this embodiment provides a pipeline pre-assembly workbench, which includes a support frame 1, the support frame 1 includes a pair of cross beams 2 and at least three positioning rods 3 slidably arranged between two of the cross beams 2 and parallel to each other, that is, the positions of all the positioning rods 3 can be adjusted, the cross section of each of the positioning rods 3 is square and a first sliding groove 4 is arranged on the top surface of each of the positioning rods 3, a pair of sliders 5 are slidably arranged in the first sliding groove 4, and a clamping hole 6 is arranged on the top surface of each of the sliders 5;

[0029] A second sliding groove connected to the first sliding groove 4 is provided on one side surface of each of the positioning rods 3, and each of the sliding blocks 5 is fixedly connected to a support plate 7 slidably connected to the second sliding groove, wherein the upper plate surface of the support plate 7 is flush with the top surface of the positioning rod 3; the workbench also includes an elastic clamping member that cooperates with two of the clamping holes 6 to fix the pipeline on the positioning rod 3.

[0030] In the above embodiment, the support frame 1 enables the two beams 2 to be in a horizontal state, the positioning rods 3 arranged on the two beams 2 are also in a horizontal state, and the upper end surface of the support plate 7 is flush with the top surface of the positioning rod 3, so that a plane for lifting the front section 9 and the rear section 10 is formed on the support frame 1. After the front section 9 and the rear section 10 are placed on the support frame 1 and positioned by elastic pressing members, the elbow joint of the front section 9 and the rear section 10 can be achieved without misalignment;

[0031] Specifically, the position of the slider 5 on each positioning rod 3 can be adjusted, so that the position of the support plate 7 can also be adjusted, so it can be used to support elbows of different sizes. The elbow generally includes a vertical portion 11 and a curved portion 12 connected to the front section 9 or the rear section 10. The positioning rod 3 supports the vertical portion 11, and the support plate 7 supports the curved portion 12, so that the elbow is in a horizontal state together; when docking, first dock the two elbows (that is, the elbow of the front section 9 is inserted into the elbow of the rear section 10), and then the front section 9 and the rear section 10 are placed as a whole on the three adjacent positioning rods 3. At the same time, the positioning rods 3 The position can be adjusted, and the two adjacent positioning rods 3 are adjusted to be located at the vertical part 11 of the rear section 10 and the vertical part 11 of the elbow of the rear section 10, and then two elastic clamps are used to position the rear section 10, and the position of the third positioning rod 3 is adjusted to be located at the vertical part 11 of the front section 9, and an elastic clamp is used to position the front section 9, and at the same time, the support plate 7 under the front section 9 and the rear section 10 cooperates with the three positioning rods 3 to make the front section 9 and the rear section 10 at the same level, and then glue can be applied to bond the two elbows; after a period of solidification, the elastic clamp can be removed to complete the pre-assembly.

[0032] like Figure 1 , 2As shown in 3, the elastic pressing member can be a U-shaped buckle 8, both ends of the U-shaped buckle 8 can be snapped into the snap hole 6, and the U-shaped buckle 8 is buckled on the pipeline so that its two ends are respectively snapped into the corresponding snap holes 6 to achieve positioning of the pipeline;

[0033] At the same time, in order to better adapt to pipes with different diameters, the elastic pressing member may also include two opposing connecting rods 13, one end of each connecting rod 13 is fixedly connected to a clamping column 14 that can be clamped into the clamping hole 6, and the other end is fixedly connected to an elastic strip 15, and one end of the elastic strip 15 away from the connecting rod 13 is fixedly connected to a fastening plate 16, and a fastening screw 17 is threadedly connected between the two fastening plates 16, wherein the fastening screw 17 is perpendicular to the two fastening plates 16;

[0034] Slide the slider 5 so that the distance between the two is greater than the diameter of the pipe, then insert a connecting rod 13 into one of the holes 6, move the pipe so that it abuts against the connecting rod 13, then insert the other connecting rod 13 into the other hole 6, then adjust the two sliders 5 so that both connecting rods 13 abut against the pipe, then connect the fastening screw 17 between the two fastening plates 16 on the two elastic strips 15. When connecting, bend the elastic strip 15 so that the two fastening plates 16 are in a vertically parallel state, and then screw in the fastening screw 17.

[0035] like Figure 1 As shown, in order to facilitate the position adjustment of the two sliders 5, an adjusting screw 18 is arranged between the two sliders 5 located in the same first sliding groove 4, wherein the adjusting screw 18 is threadedly connected to one slider 5 (that is, the adjusting screw 18 threadably penetrates the slider 5) and is rotatably connected to the other slider 5, the clamping hole 6 is vertically arranged and located above the adjusting screw 18, wherein the adjusting screw 18 is horizontally arranged and located outside the first sliding groove 4, when the position of the slider 5 is adjusted, the adjusting screw 18 can be pushed and pulled horizontally to make the two sliders 5 move as a whole in the first sliding groove 4, and the two sliders need to be adjusted. The relative position between the blocks 5 is achieved by rotating the adjusting screw 18. Specifically, since the slider 5 is also fixedly connected to the support plate 7 which is slidably connected to the second sliding groove (specifically, the slider 5 is fixedly connected to the cross bar 19 described later, and the cross bar 19 provides a limiting effect on the slider 5), the slider 5 which is rotationally connected to the adjusting screw 18 can be in a stationary state when the adjusting screw 18 is rotated, and the slider 5 which is threadedly connected to the adjusting screw 18 can be moved closer to or farther away from the other slider 5 under the drive of the adjusting screw 18. In particular, the support plate 7 is also connected to the slider 5 to ensure that the slider 5 does not separate from the positioning rod 3.

[0036] like Figure 1As shown, the slider 5 is fixedly connected to a cross bar 19 which is slidably connected to the second sliding groove, and the support plate 7 is clamped with the cross bar 19. At the same time, the cross bar 19 allows the support plate 7 to be separated from the positioning rod 3 to avoid foreign objects being stuck between the two and causing the support plate 7 and the slider 5 to be unable to slide. The clamping connection allows the support plate 7 to be removed when it is not needed. Specifically, the cross bar 19 has a square cross section, and a square hole is provided on the support plate 7 for the cross bar 19 to be clamped into. The clamping connection between the support plate 7 and the cross bar 19 is achieved through the cooperation of the square hole and the cross bar 19. In particular, setting the cross bar 19 to be square can enable the support plate 7 to be flush with the top surface of the positioning rod 3 after clamping.

[0037] like Figure 1 As shown, in order to ensure the level of the workbench, a level ruler 20 parallel to the crossbeam 2 is fixedly connected to the crossbeam 2, and the support frame 1 also includes columns 21 fixedly connected to both ends of the two crossbeams 2, each of the columns 21 is perpendicular to the crossbeam 2, and a height adjustment component is provided at one end of the column 21 away from the crossbeam 2. The level ruler 20 is used to check whether the workbench is in a horizontal state. If it is not horizontal, each column 21 can be adjusted by the height adjustment component to achieve the leveling of the workbench.

[0038] Specifically, Figure 1 As shown, the height adjustment component includes a support screw 22 threadedly connected to the column 21, the support screw 22 is arranged coaxially with the column 21, and a cavity 28 for the support screw 22 to enter is arranged in the column 21, and the support screw 22 is also threadedly sleeved with a first gear 23 rotatably arranged in the column 21, and a motor 24 is fixedly installed outside the column 21, and the rotating shaft of the motor 24 is fixedly connected to a second gear 25 meshing with the first gear 23, wherein the height position of the first gear 23 relative to the column 21 is fixed, and when the motor 24 rotates, the first gear 23 is driven to rotate through the second gear 25, thereby realizing the telescopic adjustment of the support screw 22. Construction sites are often uneven. When installing a workbench on an uneven bottom surface, each support screw 22 can be telescopically adjusted by a motor 24. At the same time, in order to facilitate the installation and use of the workbench on soil ground, a pad 26 is fixedly provided at one end of the support screw 22 away from the crossbeam 2. The pad 26 directly rests on the ground. When the motor 24 rotates, the support screw 22 can be extended into or withdrawn from the column 21, thereby raising or lowering the column 21, and then adjusting the workbench horizontally. In particular, when the motor 24 rotates, the pad 26 can be retracted into the column 21, and when used on horizontal ground, the pad 26 is retracted into the column 21 (wherein, an annular groove 27 for accommodating the pad 26 is recessed on the lower end surface of the column 21).

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
