Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for using steel bars, and in particular relates to an inlet safety protection device for a steel bar straightening machine. Background Art

[0002] Rebar is an essential raw material in modern construction. It is a necessary process to make the rebar into a keel or support frame through bending, welding, arranging and other processes before pouring concrete. Rebars are generally rolled into coils for easy storage and transportation. When using rebars, they need to be straightened by a rebar straightening machine. Pulling out the rolled rebars and passing them into the rebar straightening machine is the first step in straightening the rebars. At this time, the rebars are curled and spiraled into the rebar straightening machine. As the equipment runs, the bent rebars will swing, especially when the rebars are close to the end, the swing amplitude is larger, and it is easy to injure people around. In order to solve the problem of rebar swinging and injuring people, some cages are made in modern technology to prevent the rebars from swinging, but the opening position of such cages is wide and straight, and the opening is high, which cannot well limit the swing amplitude of the rebars, causing the rebars to swing up and down with a large amplitude, and drive the swing in the left and right directions, which will also bring danger to people near the cage entrance.

[0003] The Chinese utility model patent application number CN201821401446.5 discloses a retractable steel bar straightening protection device, which includes a straightening machine and a protection cage, the opening of which is the largest and then gradually decreases at the rear. The device can prevent the swing of the steel bars from causing contact injuries to people, but its opening is wide and straight, which cannot well limit the swing of the steel bars near the entrance, causing the steel bars to swing greatly at the entrance of the protection cage and before the entrance, which can easily hit the surrounding staff and cause injuries. Utility Model Content

[0004] The purpose of the utility model is to propose a safety protection device for the entrance of a steel bar straightening machine in view of the problems in the prior art, such as the curled steel bars at the entrance of the steel bar straightening machine swinging around and the swinging amplitude is too large, which is easy to hit the surrounding personnel, and the entrance of the existing protective cage is wide and straight, resulting in poor protection effect. The utility model device can limit the swing amplitude of the steel bar when the steel bar is straightened, and prevent the steel bar from swinging up and down too much, thereby better protecting the safety of the surrounding personnel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A steel bar straightening machine entrance safety protection device comprises a steel bar straightening machine, and also comprises an entrance disc, a middle protection ring and a rear protection ring which are arranged in sequence; the entrance disc is provided with a steel bar entrance; the steel bar entrance corresponds to the entrance of the steel bar straightening machine; protection steel bars are distributed and connected between the edge of the entrance disc and the middle protection ring; protection steel bars are also distributed and arranged between the middle protection ring and the rear protection ring; the position of the rear protection ring is lower than the entrance disc and the middle protection ring; the opening of the rear protection ring is inclined downward.

[0007] The rebar straightening machine is a horizontal rebar straightening machine commonly seen in the prior art, and is used to straighten curled rebars; the entrance disc, the middle protective ring and the rear protective ring plus the protective steel bar form a protective mesh frame, which can prevent the curled part of the rebar from swinging during straightening and causing harm to surrounding personnel; the rebar enters from the rebar entrance and then enters the entrance of the rebar straightening machine; the protective steel bar is used to limit the swing of the rebar bar; the position of the rear protective ring is lower than the entrance disc and the middle protective ring, and the opening is tilted downward. Such a design allows the rebar to enter the rear protective ring at a low position, and the downward tilted rear protective ring can prevent the rebar bar from swinging too much up and down, and also avoid the situation where the up and down swing of the rebar bar leads to increased left and right swinging, thereby reducing the risk of the rebar bar hitting surrounding personnel.

[0008] As a further technical improvement, a protective net is connected between adjacent protective steel bars. The protective net further enhances the protective effect and prevents the steel bars from swinging out; the mesh of the protective net does not need to be too small and needs to be made of wear-resistant and strong materials.

[0009] As a further technical improvement, the protection net is provided with a wire pulling gap, which is used to pull the steel bar into the steel bar entrance.

[0010] As a further technical improvement, two sets of corresponding rollers are arranged in the steel bar entrance. When the steel bar passes through the steel bar entrance, the two sets of rollers rotate to facilitate the steel bar to pass through.

[0011] As a further technical improvement, downward supporting feet are provided on the inlet disc, the middle protection ring and the rear protection ring.

[0012] As a further technical improvement, reinforcement rings are provided between the protection steel bars, and the reinforcement rings enhance the firmness of the protection net and the protection steel bars.

[0013] As a further technical improvement, the diameters of the middle protection ring and the rear protection ring are larger than the diameter of the inlet disc. Such a design can avoid affecting the entry and passage of the steel bars.

[0014] The method for using the above-mentioned steel bar straightening machine entrance safety protection device is as follows:

[0015] When in use, place the steel bar entrance on the entrance disc facing the entrance of the steel bar straightening machine, pull out the steel bar of the steel bar coil, and pass it through the rear protection ring and the middle protection ring in turn, and finally enter the steel bar entrance and pass into the steel bar straightening machine; start the equipment, then the steel bar is drawn into the steel bar straightening machine, and the curled steel bar at the rear will swing; when the steel bar swings and touches the rear protection ring, it is restricted by the edge of the rear protection ring and cannot swing upward significantly, and it helps to further restrict the left and right swing of the steel bar, thereby preventing the steel bar from swinging too much and injuring people around.

[0016] The technical solution of the utility model has the following beneficial effects:

[0017] 1. The utility model device forms a protective net frame through the entrance disc, the middle protective ring and the rear protective ring plus the protective steel bar, which can prevent the curled part of the steel bar from swinging during straightening and causing harm to the surrounding personnel.

[0018] 2. The rear protection ring of the utility model is located low, and the opening is tilted downward, which can limit the up and down swinging range of the steel bar, thereby also reducing the left and right swinging range, further protecting the safety of surrounding personnel.

[0019] 3. The utility model provides a protective net on the adjacent protective steel bars, which can further limit the swing of the steel bars, making the device safer during use. BRIEF DESCRIPTION OF THE DRAWINGS
