Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a brakeable linear roll material release device. Background Technology

[0002] In existing technologies, the release device for linear coils (such as cables, external bundled steel strands, etc.) is generally set longitudinally. In use, the coil of linear coil is placed on the pay-off reel, and the end of the cable in the coil is pulled manually or by a winch, causing the coil and pay-off reel to rotate together to release the cable. However, in actual use, the pay-off reel does not have a braking mechanism, and the coil is usually heavy and has rotational inertia. Even if the pulling is stopped, it will continue to rotate for a certain period of time, which makes it impossible to stop the rotation of the coil and pay-off reel in time after the cable is released. This results in the cable being released too much, which makes it inconvenient for workers to tighten the over-released cable when storing and organizing it.

[0003] Therefore, it is necessary to study a brakeable linear roll release device. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a brakeable linear roll release device, which can effectively solve the problem of excessive roll release caused by the inability of existing roll release devices to stop the roll release reel rotation in time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A brakeable linear roll release device includes a base plate, a rotating shaft, a feed plate, a brake plate, and a braking mechanism;

[0007] Support legs are arranged below the base plate;

[0008] The middle part of the rotating shaft is vertically rotatable at the center of the base plate via a bearing;

[0009] The pay-off reel is fixedly mounted on the upper part of the rotating shaft and horizontally distributed above the base plate;

[0010] The brake disc is fixedly mounted on the lower part of the rotating shaft and horizontally distributed below the base plate;

[0011] The braking mechanism includes a mounting base, a bidirectional screw, a first slider, a second slider, a first gripper, a second gripper, and a braking block;

[0012] The mounting base is fixed to the lower surface of the base plate. A clearance hole for the rotating shaft is provided in the middle of the mounting base. A first rotating rod and a second rotating rod are vertically fixed at intervals on the lower surface of the mounting base.

[0013] The bidirectional screw is mounted on the mounting base via a screw seat. The bidirectional screw has two opposite threaded sections, and the two threaded sections are respectively threaded to a first slider and a second slider. The first slider and the second slider are symmetrically distributed on both sides of the rotating shaft.

[0014] One end of the first gripper is rotatably mounted on the first rotating rod, and the other end of the first gripper is hinged to the first slider.

[0015] One end of the second gripper is rotatably mounted on the second rotating rod, and the other end of the second gripper is hinged to the second slider.

[0016] The first and second grippers are symmetrically distributed on both sides of the rotating shaft, and brake blocks are fixed on the opposing surfaces of the first and second grippers.

[0017] Furthermore, two sets of screw seats are spaced apart, and a guide rod is fixedly connected between the two sets of screw seats. The first slider and the second slider are slidably fitted onto the guide rod.

[0018] Furthermore, a hand crank is installed at one end of the bidirectional screw.

[0019] Furthermore, the surface of the brake block facing the outer circle of the brake disc is an arc-shaped surface adapted to the outer circle of the brake disc.

[0020] Furthermore, the lower circumference of the wire feeding reel is evenly provided with reversing wheels, and the wheel surface of the reversing wheels is in contact with the base plate.

[0021] Furthermore, guardrails are fixed at intervals along the outer circumference of the base plate, and handrails are fixedly connected to the top of the guardrails.

[0022] The beneficial effects of the above technical solution are:

[0023] This invention rotatably positions the middle of the rotating shaft at the center of the base plate using a bearing, allowing the lower part of the rotating shaft to extend downwards beyond the base plate. A brake disc is fixedly mounted on the lower part of the rotating shaft, and a braking mechanism adapted to the brake disc is correspondingly fixed below the base plate. The braking mechanism uses a bidirectional screw to bring the two grippers closer together synchronously, causing the brake blocks on the grippers to rub against the side wall of the brake disc, stopping the rotation of the brake disc, the rotating shaft, and the pay-off reel fixedly mounted on the upper part of the rotating shaft. This promptly stops the pay-off. When no more pay-off is needed, the worker can quickly stop the pay-off by operating the braking mechanism, preventing excessive cable pay-off. This effectively solves the problem of existing pay-off devices failing to stop the pay-off reel rotation in time, resulting in excessive pay-off. It also eliminates the need to re-tighten the over-paid cable during storage and organization, making it more convenient to use. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0030] This embodiment aims to provide a brakeable linear coil release device, which is mainly used for releasing linear coils such as cables and external bundled steel strands. It addresses the problem that existing coil release devices cannot stop the coil reel rotation in time, resulting in excessive coil release, which necessitates workers to tighten the excessively released cables during storage and organization.

[0031] A brakeable linear roll release device, such as Figure 1 It includes a base plate 1, a rotating shaft 2, a wire feeding reel 3, a brake disc 4, and a braking mechanism 5; since the brake disc 4 and the braking mechanism 5 are arranged below the base plate 1, four support legs 6 are welded and fixed to the bottom of the base plate 1 to support the base plate 1 and provide space for the installation of the brake disc 4 and the braking mechanism 5; for example Figure 3 The middle part of the rotating shaft 2 is vertically rotatably set at the center of the base plate 1 through the bearing 201, so that the bearing 201 can rotate relative to the base plate 1; the pay-off reel 3 is fixedly mounted on the upper part of the rotating shaft 2 through connecting parts such as keys and is horizontally distributed above the base plate 1, so that the pay-off reel 3 can rotate synchronously with the rotating shaft 2. The upper part of the pay-off reel 3 is used to place the linear roll material. When one end of the linear roll material is dragged, the linear roll material will drive the pay-off reel 3 and the rotating shaft 2 to rotate, thereby paying off the wire. This pay-off method and its principle are widely used in the prior art, and will not be elaborated here.

[0032] like Figure 3The brake disc 4 is fixedly mounted on the lower part of the rotating shaft 2 by connecting parts such as keys and is horizontally distributed below the base plate 1, so that the brake disc 4 and the rotating shaft 2 rotate synchronously.

[0033] like Figure 2 , Figure 3 and Figure 4 The braking mechanism 5 includes a mounting base 8, a bidirectional screw 7, a first slider 9, a second slider 10, a first gripper 11, a second gripper 12, and a brake block 13. The mounting base 8 is screwed to the lower surface of the base plate 1. The mounting base 8 has a ring-shaped structure. A clearance hole 801 for the rotating shaft 2 is opened in the middle of the mounting base 8. A first rotating rod 802 and a second rotating rod 803 are vertically fixed at intervals on the lower surface of the mounting base 8. The bidirectional screw 7 is mounted on the mounting base 8 through a screw seat 804. The screw seat 804 is distributed at both ends of the bidirectional screw 7 and is used to support the bidirectional screw 7. The bidirectional screw 7 has two opposite threaded sections. The first slider 9 and the second slider 10 both have through threaded holes. The first slider 9 and the second slider 10 are threadedly connected to the two threaded sections of the bidirectional screw 7 through the threaded holes, respectively. The first slider 9 and the second slider 10 are symmetrically distributed on both sides of the rotating shaft 2. When the threaded rod rotates, the first slider 9 and the second slider 10 can move closer or further apart synchronously. One end of the first gripper 11 is rotatably mounted on the first rotating rod 802, and the other end of the first gripper 11 is hinged to the first slider 9. One end of the second gripper 12 is rotatably mounted on the second rotating rod 803, and the other end of the second gripper 12 is hinged to the second slider 10. The first gripper 11 and the second gripper 12 are symmetrically distributed on both sides of the rotating shaft 2. Brake blocks 13 are fixed to the facing surfaces of the first gripper 11 and the second gripper 12 with corresponding screws. When the first slider 9 and the second slider 10 gradually move inward, the brake blocks 13 on the first gripper 11 and the second gripper 12 can simultaneously abut against the side wall of the brake disc 4 and clamp and brake, forming a brake-holding structure.

[0034] To facilitate the movement of the two sliders, a guide rod 14 is interference-fitted between the two sets of screw seats 804. The guide rod 14 is arranged parallel to the bidirectional screw 7. The first slider 9 and the second slider 10 are both slidably mounted on the guide rod 14 to limit and guide the two sliders.

[0035] In this embodiment, the installation method of the braking mechanism 5 is as follows: First, fix the mounting base 8 on the lower surface of the base plate 1, fix the first rotating rod 802 and the second rotating rod 803 on the mounting base 8 respectively, and fix the screw seat 804 on the mounting base 8 respectively; then, install the first clamping claw 11 and the second clamping claw 12 on the first rotating rod 802 and the second rotating rod 803 respectively, and install the brake block 13; then, pass the bidirectional screw 7 through the screw seat 804, and simultaneously thread the first slider 9 and the second slider 10 through the screw. At this time, the positions of the first slider 9 and the second slider 10 can be adjusted individually by rotation; adjust the first slider 9 and the second slider 10 to be symmetrical left and right, so that the two brake blocks 13 can simultaneously abut against the brake disc 4, and then hinge the first clamping claw 11 and the second clamping claw 12 to the first slider 9 and the second slider 10 respectively. At this time, the positions of the first slider 9 and the second slider 10 can no longer be adjusted individually by rotation; finally, install the guide rod 14 to complete the installation of the braking mechanism 5.

[0036] To facilitate workers' operation of rotating the bidirectional screw 7 to trigger the braking mechanism 5, a hand crank 15 is installed at one end of the bidirectional screw 7.

[0037] In order to facilitate better friction braking between the brake block 13 and the side wall of the brake disc 4, the surface of the brake block 13 facing the outer circle of the brake disc 4 is an arc-shaped surface that matches the outer circle of the brake disc 4, so as to increase the contact area during braking.

[0038] To reduce the load at the connection point between the pay-off reel 3 and the rotating shaft 2, a frame is fixed below the pay-off reel 3 for support. The frame is made of eight circumferentially distributed square steel pipes welded together. Eight reversing wheels 16 are evenly installed on the lower surface of the frame. The wheel surfaces of the reversing wheels 16 are in contact with the base plate 1. When the pay-off reel 3 rotates, the reversing wheels 16 can rotate on the base plate 1, preventing the outer circle of the pay-off reel 3 from being suspended in the air, thereby reducing the load at the connection point between the pay-off reel 3 and the rotating shaft 2.

[0039] To prevent the cable from being thrown out due to excessively fast cable feeding from the cable feeding reel 3, guardrails 17 are fixed at intervals along the outer circumference of the base plate 1. Handrails 18 are fixedly connected to the top of the guardrails 17. This not only prevents the cable from being thrown out and improves the safety of use, but also facilitates transportation and movement.
