DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] EMBODIMENT

[0025] AsFigures 1 to 5 The hydraulic tensioning all-in-one machine provided by the embodiment is convenient to disassemble, and is different from the existing all-in-one frame form. Each connecting piece is combined and used in a modular and movable connection manner, including a stand 1, a traction rod 2, an upper beam 6, a lower beam 9, a vehicle beam 13, a traction roller 11 and a bearing column 19 movably connected with each other.

[0026] The traction rod 2 is installed on the front surface of the stand 1 through a connecting piece 3, the connecting piece 3 is hinged to the traction rod 2 through a connecting pin 4, and a clamping groove is formed on each side of the connecting piece 3 and matched with a limiting column 5 integrally formed on each side of the hinged end of the traction rod 2. When traction is performed, the limiting column 5 and the clamping groove limit the angle of the traction rod 2 (i.e., the angle of the traction rod 2 is not too large) to prevent the traction rod 2 from being deformed due to the angle being too large.

[0027] A C-shaped reinforcing plate 7 is sleeved outside the stand 1, the reinforcing plate 7 is penetrated by the upper beam 6 through a penetration opening corresponding to a reserved slot I, and the reserved slot I on the stand 1 is also penetrated by the upper beam 6. An opening end of the reinforcing plate 7 is provided with a plurality of groups of symmetrical insertion holes, and a front end of the upper beam 6 is also provided with a plurality of groups of insertion slots corresponding to the insertion holes and are sequentially penetrated and fixed by a plurality of reinforcing bolts 8 (limited by nuts) to ensure the stability of the connection between the upper beam 6 and the stand 1 and to reinforce the reserved slot I to prevent deformation of the reserved slot I due to turning and traction.

[0028] A front end of the lower beam 9 is inserted into a reserved slot II on the stand 1, the upper beam 6 and the lower beam 9 are connected through the bearing column 19, and a bracket 10 for installing an oil tank and a hydraulic system is hinged to a side surface of the lower beam 9 through a hinge. A bottom end of the bracket 10 is hinged to a support rod (a non-hinged end of the support rod abuts against a side wall of the lower beam 9) through a spring pin. An insertion slot is formed in the lower beam 9 for the support rod 10 to be inserted into, so that stable support is formed. After disassembly, the bracket 10 can be folded for storage, thereby reducing the space occupied.

[0029] It should be noted that the hydraulic system includes components such as a hydraulic pump, a hydraulic oil tank, a hydraulic cylinder, a pressure regulating valve, a flow valve, a reversing valve, a filter, a safety valve, and hydraulic oil. The hydraulic pump converts mechanical energy into liquid pressure energy to drive the hydraulic cylinder to generate the required tension to ensure the stability and safety of the cable during laying or tensioning. The hydraulic oil tank stores hydraulic oil to provide the necessary oil volume for the system; the pressure regulating valve and the flow valve control the flow rate and pressure of the hydraulic oil to adapt to different tension requirements. The filter ensures the cleanliness of the oil to prevent impurities from affecting the performance of the system, and the safety valve prevents overpressure to ensure the safe operation of the equipment. Through the coordinated action of these components, the cable tensioner can achieve precise control of the cable tension to ensure construction quality and safety, which are common components in traditional existing equipment.

[0030] The traction roller 11 is installed on the right side of the upper beam 6. It should be noted thatFigure 2 The traction roller 11 shown in the middle is a roller shell without a roller body, so that the position of the cover plate 18 can be observed;

[0031] The vehicle beam 13 is installed on the upper surface of the lower beam 9, the middle part of the vehicle beam 13 is clamped into the installation groove of the lower beam 9, the middle part of the upper surface of the vehicle beam 13 is provided with a positioning groove 14, the cover plate 18 hinged by the hinge is covered on the upper surface of the vehicle beam 13, and the screw holes 15 matched with each other are formed in the cover plate 18, the vehicle beam 13 and the positioning groove 14, and are fixed by bolts, the two ends of the vehicle beam 13 are respectively provided with the connecting seats 12, and the ends, away from each other, of the two connecting seats 12 are both connected with the wheels 17 through the rotating shafts 16.

[0032] It should be noted that the bottom end of the bearing column 19 is inserted into the bearing groove formed in the top of the lower beam 9, and the top end of the bearing column 19 penetrates through the through groove formed in the upper beam 6, the diameter value of the penetrating end of the bearing column 19 is less than the diameter value between the upper beam 6 and the lower beam 9, that is, a bearing surface is formed, so that the upper beam 6 can be erected to the bearing surface.

[0033] It should be noted that the structure of the utility model can be realized in various different forms, and is not limited to the embodiments, any equivalent transformation made by the person skilled in the art according to the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, for example, loading and unloading of other articles, is included in the protection scope of the utility model.
