Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe production, in particular to a wire coil braking device for a seam welding machine. Background Art

[0002] Concrete pipes play an important role in municipal construction and undertake important dredging tasks such as urban drainage and agricultural irrigation. They mainly include prestressed steel cylinder concrete pipes, steel bar wrapped prestressed steel cylinder concrete pipes, prestressed concrete pipes, reinforced concrete drainage pipes, etc. Concrete pipes are mainly made of a core mold skeleton composed of steel bars and steel wires and concrete. Therefore, the core mold skeleton is an important structure of the concrete pipe.

[0003] The core mold skeleton is mainly composed of transverse steel bars and iron wires welded to the transverse steel bars. During the production process, the wire reel rotates at high speed when driven by the seam welding machine. At the end of seam welding, the wire reel still rotates at high speed due to inertia. Usually, on-site workers use manual braking, that is, stepping on it or tying iron blocks to increase the weight, increasing the contact area with the ground for friction deceleration braking, which poses certain safety hazards. For this reason, we proposed a wire reel braking device for seam welding machine to solve the above problems. Utility Model Content

[0004] The present application provides a wire coil braking device for a rolling welding machine, which solves the problem of excessive working space caused by the wire coil releasing too much wire due to inertia when the rolling machine stops during the preparation of the core mold skeleton of the concrete pipe.

[0005] The present application provides a wire coiling brake device for a rolling welding machine, comprising a base, a cavity being provided in the base, a rotating shaft being installed at the bottom of the cavity, the rotating shaft extending to the upper end of the base, and a turntable being fixed on the rotating shaft, a wire coiling roller being installed on the turntable, a limit disk being installed at one end of the rotating shaft located in the cavity, a limit slot plate which reciprocates in the cavity, the limit slot plate corresponding to the limit disk, and the limit slot plate being reciprocated by a second cylinder.

[0006] Preferably, a support plate is installed in the cavity, a rod is movably inserted on the support plate, a push plate is fixed to one end of the rod away from the limit plate, the end of the second cylinder is installed on the push plate, and the limit slot plate is installed on the other side of the rod.

[0007] Preferably, a plurality of insertion rods are provided on the same support plate.

[0008] Preferably, a roller is installed at the bottom of the turntable, and a track corresponding to the roller is installed on the base.

[0009] Preferably, a bracket is installed on one side of the base, a fixed wheel and a movable wheel are installed on the opposite side walls within the bracket, a slider is installed on the rotating shaft of the movable wheel, and a slide groove is provided on the opposite side walls within the bracket, the slider is installed on the slide groove, U-shaped frames are installed on both sides of the movable wheel, a first cylinder is installed on the top of the bracket, and the end of the first cylinder is installed on the U-shaped frame.

[0010] Preferably, a plurality of support discs are installed on the wire coiling roller.

[0011] Preferably, there are two limiting slot plates, which are symmetrically arranged on both sides of the limiting plate.

[0012] Preferably, the top of the wire coiling roller is bent toward the center.

[0013] It can be seen from the above technical solution that the present application provides a wire coiling brake device for a rolling welding machine. When in use, the wire coil is hoisted onto the wire coiling roller by a crane, and then one end of the wire coil is pulled out and installed on the rolling welding machine. When the mixed welding machine is working, the steel wire is wound around the core mold skeleton and the wire coil is pulled to rotate. When the wire coiling is completed, the mixed welding machine stops working. At this time, due to inertia, the wire coiling roller continues to rotate. In the present application, the second cylinder is linked to the rolling welding machine. When the rolling welding machine stops running, the second cylinder pushes the limit slot plate to move, so that it conflicts with the limit disk on the rotating shaft, thereby generating greater friction on the limit disk to make it stop rotating quickly, thereby completing the braking work of the wire coil.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the setting of the base and the cavity, the brake of the wire reel can be installed in the cavity, so that the upper part of the base maintains the original design and will not affect the surrounding workers during braking;

[0016] 2. By setting the limit plate and the limit slot plate, the limit plate is installed in the cavity. The purpose of braking the wire reel is achieved by limiting the limit plate, which is convenient for control. Moreover, the braking structure is located in the cavity and will not be affected by existing collisions, thereby reducing the impact on the use of the equipment.

[0017] To sum up, when the present application is in use, relevant moving parts can be installed on the base for movement. When the seam welding machine stops running, it can quickly brake to avoid excessive opening of the steel wire, affecting the factory space and reducing the danger to surrounding workers. In addition, the braking-related parts of the present application are all located in the cavity, which can effectively protect its structure and avoid damage caused by collision, thereby not affecting the normal use of the wire reel equipment.

DETAILED DESCRIPTION

[0024] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] See also Figure 1-4 , a wire reel brake device for a roll welding machine, the present application is used to brake the wire reel on one side of the roll welding machine, after the roll welding machine is turned off, the wire reel can stop quickly, to prevent the wire reel from rotating due to inertia, causing the wound wire to open, affecting the surrounding workers, specifically, including a base 1, the present application base 1 is a truncated cone, which is welded by enclosing fan-shaped steel plates, with reinforced steel rings and reinforcing ribs welded inside, and can also be designed into a cylindrical shape to support the wire reel, the bottom of the base 1 can be installed with rollers for easy movement on the track, and a pad block can also be provided to facilitate the movement of the present application by a forklift;

[0026] A cavity is provided in the base 1, which forms a protective cavity while supporting it. A rotating shaft 7 is installed at the bottom of the cavity. The bottom of the rotating shaft 7 is connected to the base 1 through a thrust bearing. The rotating shaft 7 extends to the upper end of the base 1, and a turntable 6 is fixed on the rotating shaft 7. The present application supports the wire reel through the turntable 6, and the turntable 6 rotates on the base 1 through the rotating shaft 7. A wire coiling roller 4 is installed on the turntable 6. When installing, the wire reel is sleeved on the wire coiling roller 4 to complete the installation of the wire reel. In order to improve the installation efficiency of the wire reel, the top of the wire coiling roller 4 is bent toward the center to facilitate passing through the center bundle hole of the wire reel, and a plurality of supporting discs 5 are installed on the wire coiling roller 4 to provide certain support to the wire coiling roller 4 and reduce the deformation of each wire coiling roller 4 during collision.

[0027] The rotating shaft 7 is located at one end of the cavity and a limit plate 10 is installed. The limit plate 10 is made of waste brake pads, which have good wear resistance and friction, and can withstand large forces without deformation or tearing. The limit slot plate 12 moves back and forth in the cavity, and the limit slot plate 12 corresponds to the limit plate 10. That is, when the limit slot plate 12 moves, the limit plate 10 can be stuck in the limit slot plate 12, and the friction force on both sides of the limit slot plate 12 is used to frictionally limit the limit plate 10, thereby achieving the braking effect on the wire roller 4. In this application, the limit slot plate 12 moves back and forth through the second cylinder 8, has a good execution action, and can provide overload protection for the limit slot plate 12. The second cylinder 8 is executed by compressed gas and has a certain rebound space to avoid the emergency stop caused by locking the limit plate 10 at one time.

[0028] A support plate 11 is installed in the cavity, and the support plate 11 is fixed in the base 1, which can provide a certain support to the cavity. A rod 15 is movably inserted on the support plate 11, and the rod 15 can move back and forth on the support plate 11. A push plate 9 is fixed to the end of the rod 15 away from the limit plate 10. A plurality of rods 15 are provided on the same support plate 11, and the plurality of rods 15 are controlled by a push plate 9 to improve the stability of the rod 15 during reciprocating movement. The end of the second cylinder 8 is installed on the push plate 9, and the limiting slot plate 12 is installed on the other side of the rod 15. In this application, the second cylinder 8 controls the reciprocating movement of the limiting slot plate 12 through the push plate 9 and the rod 15, which can not only provide better protection for the second cylinder 8, but also ensure stable and reliable reciprocating movement.

[0029] In the present invention, in order to further improve the stability of the turntable 6 during operation, a roller 13 is installed at the bottom of the turntable 6, and a track 14 corresponding to the roller 13 is installed on the base 1. The side position of the turntable 6 is supported by the roller 13 to reduce the force on the rotating shaft 7, thereby improving the bearing capacity of the turntable 6.

[0030] In some embodiments, a bracket 2 is installed on one side of the base 1. The bracket 2 consists of two vertical rods and a plurality of horizontal rods fixed between the two vertical rods. A fixed wheel 20 and a movable wheel 17 are installed on the opposite side walls in the bracket 2, wherein the fixed wheel 20 is fixed in position and the movable wheel 17 can be adjusted up and down in height. Specifically, a slider 18 is installed on the rotating shaft of the movable wheel 17, and a slide groove 19 is provided on the opposite side walls in the bracket 2. The slider 18 is installed on the slide groove 19, and the movable wheel 17 is adjusted in the slide groove 19 by the slider 18. During adjustment, U-shaped frames 16 are installed on both sides of the movable wheel 17, and the U-shaped frames 16 are fixed on the rotating shafts on both sides of the movable wheel 17. A first cylinder 3 is installed on the top of the bracket 2, and the end of the first cylinder 3 is installed on the U-shaped frame 16. The first cylinder 3 adjusts the U-shaped frame 16, thereby adjusting the movable wheel 17, and then adjusting the distance between the movable wheel 17 and the fixed wheel 20;

[0031] When the present embodiment is in use, the steel wire is passed between the movable wheel 17 and the fixed wheel 20, and is introduced into the seam welding machine. When the wire is paid out, the steel wire passes normally through the movable wheel 17 and the fixed wheel 20. When the seam welding machine stops working, the first cylinder 3 presses down the movable wheel 17, so that the movable wheel 17 and the fixed wheel 20 hold the steel wire tightly, reducing the excessive outward expansion of the steel wire caused by excessive rotation of the turntable 6, thereby reducing the impact of the steel wire on the operating space. In the present embodiment, the steel wire can also be limited to align with the steel wire entry portion of the thread rolling machine.

[0032] In some embodiments, there are two limiting slot plates 12 symmetrically arranged on both sides of the limiting disk 10, which can improve the braking effect. The symmetrically arranged limiting slot plates 12 make the limiting disk 10 more evenly stressed and improve friction.

[0033] It can be seen from the above technical solution that when the present application is in use, the wire reel is hoisted onto the wire coiling roller 4 by a crane, and then one end of the wire reel is pulled out and installed on the roll welding machine. When the mixed welding machine is working, the steel wire is wound around the core mold skeleton and the wire reel is pulled to rotate. When the wire coiling is completed, the mixed welding machine stops working. At this time, due to inertia, the wire coiling roller 4 continues to rotate. In the present application, the second cylinder 8 is linked to the roll welding machine. When the roll welding machine stops running, the second cylinder 8 pushes the limit slot plate 12 to move, so that it conflicts with the limit plate 10 on the rotating shaft 7, thereby generating greater friction on the limit plate 10 to quickly stop rotating, thereby completing the braking work of the wire reel.
