Description

Technical Field

[0001] This utility model relates to the field of rebar straightening technology, and in particular to a safety protection device for a rebar straightening machine. Background Technology

[0002] Before use, coiled steel bars need to be straightened. The straightening work is generally done by a steel bar straightening machine. During the straightening process, the steel bars are prone to swinging and other deviations, which poses certain safety hazards. Traditional protective frames are generally only set at the steel bar inlet of the steel bar straightening machine, which is insufficient for the protection of the coiled steel bars and still poses a threat to the personal safety of the operators. In order to address the above-mentioned deficiencies, this application is made. Utility Model Content

[0003] The purpose of this utility model is to provide a safety protection device for a rebar straightening machine, which mainly solves the safety protection problem during the rebar straightening process and improves the protection performance.

[0004] To address the aforementioned problems, this utility model provides a safety protection device for a rebar straightening machine, comprising a base, a protective cover, a protective cover plate, a support base, and a telescopic rod. The base is provided with several columns, and the protective cover plate is movably connected to the columns. A placement space for placing rebars is formed between the protective cover plate and the base. The protective cover plate has open and closed states; in the open state, the rebar can enter the placement space. The protective cover, support base, and telescopic rod are disposed within the placement space. The protective cover has a funnel-shaped structure, allowing the rebar to pass through. The support base has an inclined support surface, and the telescopic rod is installed on the support surface of the support base. The support surface and the telescopic rod are used to support the rebar, with the telescopic rod supporting the central hole of the coiled rebar.

[0005] According to one embodiment of the present invention, the protective cover plate and the column are rotatably connected, which can be achieved by means of hinge connection, and the cover is opened by flipping.

[0006] According to one embodiment of the present invention, the protective cover is a mesh structure, including several circular structures with gradually increasing diameters, and a straight structure connected to the outer circle of the circular structures.

[0007] According to one embodiment of the present invention, the base, protective cover, protective cover plate, support base and column are all made of metal, preferably steel.

[0008] According to one embodiment of the present invention, the protective cover plate has a grid-like structure, which reduces weight.

[0009] According to one embodiment of the present invention, the cross-section of the protective cover plate is arched.

[0010] According to one embodiment of the present invention, the telescopic rod is a manual telescopic rod, which is adjusted manually for extension and retraction.

[0011] According to one embodiment of the present invention, the adjustment structure of the telescopic rod is located outside the placement space.

[0012] According to one embodiment of the present invention, the telescopic rod is an automatic telescopic rod such as an electric telescopic rod or a hydraulic telescopic rod.

[0013] The beneficial effects of this utility model are that by setting a base, a protective cover, a protective cover plate, a support seat, and a telescopic rod, a placement space for placing steel bars is formed between the protective cover plate and the base. When straightening steel bars, the steel bars pass through the protective cover, and the remaining steel bars are in the closed placement space, which greatly improves safety and facilitates the high efficiency of steel bar straightening work. In addition, this solution also sets a telescopic rod to facilitate the entry of steel bars into the placement space. Attached Figure Description

[0019] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

Example 1

[0021] A safety protection device for a rebar straightening machine, such as Figure 1 It includes a base 2, a protective cover 3, a protective cover plate 4, a support base 5, and a telescopic rod 6.

[0022] The base 2 is assembled and welded from several I-beams, with a square frame at the bottom and several columns 21 welded on both sides of the frame.

[0023] The protective cover 3 has a funnel-shaped structure. It is made of steel bars and has a mesh structure, including several circular structures with gradually increasing diameters, as well as straight structures connected to the outer circle of the circular structures.

[0024] The protective cover plate 4 is movably connected to the column 21. The protective cover plate 4 is welded from steel bars. In this embodiment, the cross-section of the protective cover plate 4 is arched. In other embodiments, a flat plate shape can be selected. The protective cover plate 4 has a grid-like structure to reduce weight.

[0025] A space for placing reinforcing bars is formed between the protective cover plate 4 and the base 2. The protective cover 3, the support base 5 and the telescopic rod 6 are arranged in the space. The protective cover plate 4 has an open and a closed state. In the open state, the reinforcing bars can enter the space. In this embodiment, the protective cover plate 4 and the column 21 are rotatably connected, which can be done by means of a hinge. When open, it is a flip-top opening.

[0026] The support base 5 is welded from I-beams and includes an inclined main support body and a diagonal brace. The two are connected and both are welded to the base 2. The main support body of the support base 5 has an inclined support surface 51. The telescopic rod 6 is installed on the support surface 51. The support surface 51 and the telescopic rod 6 are used to support the reinforcing bars. The telescopic rod 6 is supported at the center hole of the coiled reinforcing bar.

[0027] Reinforcing bars are generally placed into the placement space by hoisting machinery. Before the reinforcing bars are put in, the telescopic rod 6 is shortened to make it easier for the reinforcing bars to enter. After the reinforcing bars are put in, they come into contact with the support surface 51, and the telescopic rod is lengthened to support the reinforcing bars and prevent them from slipping. In addition, during the processing of reinforcing bars, the telescopic rod 6 can be shortened as the reinforcing bars are gradually reduced, which facilitates the efficient straightening process of the reinforcing bars.

[0028] When processing steel bars, open the protective cover plate 4, put in the steel bar to be processed, pass one end of the steel bar through the protective cover 3 and enter the steel bar straightening machine 1.

[0029] Optionally, the telescopic pole 6 can be a manual telescopic pole or an automatic telescopic pole.

[0030] When using a manual telescopic rod, the extension and retraction are adjusted manually. The adjustment structure of the telescopic rod 6 is located outside the placement space, making manual adjustment safer. For example, the telescopic rod includes a sleeve and a moving rod. The moving rod moves in the sleeve to adjust the length within the placement space to achieve extension and retraction adjustment. The other end of the moving rod is outside the placement space, and the worker can operate the moving rod from outside the placement space to achieve extension and retraction control.

[0031] When using automatic telescopic poles, electric telescopic poles, hydraulic telescopic poles, etc. can be used. Workers only need to operate the switch to control the extension and retraction, which is safer.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
