Description

Technical Field

[0001] This utility model belongs to the field of hydraulic drive equipment technology, and relates to hydraulic straighteners, especially a portable hydraulic straightener for wind turbine towers. Background Technology

[0002] Hydraulic straighteners are metal processing equipment powered by a hydraulic system. They are mainly used to correct shape deviations in metal profiles (such as H-beams, round pipes, square steel, etc.). They use hydraulic cylinders to drive straightening rollers or pressure rollers for position adjustment and deformation correction.

[0003] Existing hydraulic straighteners are inconvenient to carry when not in use. Because their outer surface is usually made of metal, they are heavy and difficult to carry and transport. They are also prone to impacts that could break other items. To solve these problems, a portable hydraulic straightener for wind turbine towers is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a portable hydraulic straightener for wind turbine towers. The technical problem this utility model aims to solve is that, since its outer surface material is usually made of metal, it is heavy, inconvenient to carry and transport, and easily damaged by impacts.

[0005] The objective of this utility model can be achieved through the following technical solutions: A portable hydraulic straightener for wind turbine towers includes a first protective shell, a second protective shell mounted on one side of the first protective shell, a hydraulic straightener body fixedly mounted inside the first protective shell, a slot formed on the surface of the first protective shell, an insert plate fixedly connected to the surface of the second protective shell, a liquid supply plug fixedly connected to the surface of the first protective shell, and a positioning and portability mechanism provided on the inner wall of the first protective shell.

[0006] The working principle of this utility model is as follows: by setting a first protective shell and a second protective shell, the main body of the hydraulic straightener is stored and protected; by setting a slot, space is provided for the insertion of the insert plate; by setting the insert plate and inserting it into the slot, the installation of the first protective shell and the second protective shell is kept stable; by setting a positioning and carrying mechanism, quick disassembly and positioning are achieved and it is easy to carry.

[0007] The positioning and portable mechanism includes a positioning pin that is slidably connected to the inner wall of the first protective shell. The positioning pin is adapted to be inserted into the insert plate. A carrying handle is fixedly connected to the surface of the hydraulic orthosis body. An external thread is formed on the surface of the hydraulic orthosis body. An internal thread cap is threadedly connected to the surface of the external thread.

[0008] The above structure provides space for the insertion of the insert plate by setting a positioning pin, facilitates the transport and protection of the hydraulic straightener body by setting a carrying handle, and provides safety protection for the output end of the hydraulic straightener body when not in use by setting an internal thread cap that mates with the external thread.

[0009] A first return spring is sleeved on the surface of the positioning pin. One end of the first return spring is fixedly connected to the surface of the positioning pin, and the other end of the first return spring is fixedly connected to the surface of the first protective shell.

[0010] With the above structure, the first return spring is used to keep the positioning pin stable inside the insert plate.

[0011] A fixing plate and a protective cylinder are fixedly connected to the surface of the first protective shell. A trapezoidal plate is fixedly connected to the surface of the first protective shell. A trapezoidal plate is slidably connected to the inner wall of the protective cylinder. The trapezoidal plate is adapted to the inner wall of the fixing plate.

[0012] By adopting the above structure and setting a trapezoidal plate, the overall connection with the fixed plate is kept stable, preventing the first protective shell and the second protective shell from being separated due to vibration when rolling on the ground.

[0013] A pull rod is slidably connected to the inner wall of the protective cylinder. One end of the pull rod is fixedly connected to the surface of the trapezoidal plate, and a second return spring is sleeved on the surface of the pull rod.

[0014] With the above structure, by setting a pull rod, pulling the pull rod drives the trapezoidal plate to move, compressing the second return spring to shorten it.

[0015] One end of the second return spring is fixedly connected to the inner wall of the protective cylinder, and the other end of the second return spring is fixedly connected to the surface of the trapezoidal plate. The inner wall of the fixed plate is rotatably connected to a rotating shaft, and rollers are fixedly connected to both ends of the rotating shaft.

[0016] By adopting the above structure, a rotating shaft is set and a pair of rollers are installed. By setting the rollers, the first protective shell and the second protective shell as a whole can move by friction on the ground, saving carrying effort.

[0017] Compared with the prior art, the present invention has the following advantages: In this invention, the hydraulic orthosis body is protected by a first protective shell and a second protective shell to prevent collision with external objects. The operator can carry the hydraulic orthosis body by lifting the carrying handle. If the operator feels tired, the operator can tie the surface of the carrying handle with a rope, place the first and second protective shells on the ground, and drag the rope. Multiple rollers rub against the ground, reducing the physical effort required for carrying and making it easy to carry. Attached Figure Description

[0021] like Figures 1-4 As shown, a portable hydraulic straightener for wind turbine towers includes a first protective shell 1, a second protective shell 2 installed on one side of the first protective shell 1, a hydraulic straightener body 7 fixedly installed inside the first protective shell 1, a slot 11 opened on the surface of the first protective shell 1, an insert plate 10 fixedly connected to the surface of the second protective shell 2, a liquid supply plug 4 fixedly connected to the surface of the first protective shell 1, and a positioning and carrying mechanism provided on the inner wall of the first protective shell 1.

[0022] The positioning and portable mechanism includes a positioning pin 8 that is slidably connected to the inner wall of the first protective shell 1. The positioning pin 8 is plugged into and adapted to the insert plate 10. A carrying handle 6 is fixedly connected to the surface of the hydraulic corrector body 7. An external thread 18 is opened on the surface of the hydraulic corrector body 7. An internal thread cap 3 is threadedly connected to the surface of the external thread 18.

[0023] A first return spring 9 is sleeved on the surface of the positioning pin 8. One end of the first return spring 9 is fixedly connected to the surface of the positioning pin 8, and the other end of the first return spring 9 is fixedly connected to the surface of the first protective shell 1.

[0024] A fixing plate 13 and a protective cylinder 15 are fixedly connected to the surface of the first protective shell 1. A trapezoidal plate 14 is fixedly connected to the surface of the first protective shell 1. The trapezoidal plate 14 is slidably connected to the inner wall of the protective cylinder 15. The trapezoidal plate 14 is adapted to the inner wall of the fixing plate 13.

[0025] A pull rod 16 is slidably connected to the inner wall of the protective cylinder 15. One end of the pull rod 16 is fixedly connected to the surface of the trapezoidal plate 14, and a second return spring 17 is sleeved on the surface of the pull rod 16.

[0026] One end of the second return spring 17 is fixedly connected to the inner wall of the protective cylinder 15, and the other end of the second return spring 17 is fixedly connected to the surface of the trapezoidal plate 14.
