Description

Technical Field

[0001] This utility model relates to the field of winch braking technology, specifically to a braking device. Background Technology

[0002] A winch is a mechanical device that uses a steel wire rope wound on a drum to move a load. It is mainly used for traction of vehicles in underground mines or on the surface, for moving supports in coal mining faces, and for other auxiliary transportation work.

[0003] When the winch brakes, the brake pads need to be engaged by the brake handle to hold the brake wheel, and then the brake pads are limited to prevent them from rotating, thus achieving braking. Currently used emergency braking devices are prone to deformation or cracking when the brake pads are engaged during braking, which can cause the brake pads to move too far, resulting in brake failure or injury to the operator's hand due to the rapid rebound of the brake handle. Utility Model Content

[0004] In view of the shortcomings of the existing technology, a braking device is proposed, which solves the problem of easy deformation or cracking of the braking device in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A braking device includes a reinforcing part for strengthening the connection between a limiting part and a supporting part. A limiting groove is provided below the limiting part to cooperate with a protrusion on the brake pad to limit the brake pad, thereby preventing the brake pad from moving and achieving braking.

[0007] Furthermore, the limiting part is specifically a horizontally arranged upper baffle, which is perpendicular to the supporting part and fixedly connected to the supporting part. The protrusion abuts against the upper baffle to limit the brake plate.

[0008] Furthermore, the support includes a standing leg, the upper end surface of which is fitted and fixedly connected to the bottom surface of the upper baffle. The reinforcing part includes reinforcing plates located on both sides of the standing leg, and the limiting groove is located between the two reinforcing plates.

[0009] Furthermore, the reinforcing plate is in the shape of a right triangle, and the two right-angled sides of the right triangle are fixedly connected to the upper baffle and the standing leg respectively to enhance the connection strength between the upper baffle and the standing leg.

[0010] Furthermore, the width of the standing leg is the same as the width of the upper baffle, and the right-angled edges of the triangular surface of the reinforcing plate are fixedly connected to the sides of the standing leg and the upper baffle, respectively.

[0011] Furthermore, the width of the standing leg is smaller than the width of the upper baffle, the standing leg is fixedly connected to the middle of the upper baffle, the side of the reinforcing plate is fixedly connected to the side of the standing leg, and the upper surface of the reinforcing plate is fixedly connected to the bottom surface of the upper baffle.

[0012] Furthermore, the reinforcing part also includes a connecting plate, which is located in the limiting groove. The connecting plate has two sides that are perpendicular to each other, and the two sides are fixedly connected to the surface of the standing leg and the surface of the upper baffle, respectively.

[0013] Furthermore, the support also includes a base, the standing leg is arranged perpendicular to the base, and the base has two mounting holes symmetrically arranged about the standing leg, through which the braking device is fixed to the periphery of the brake pad.

[0014] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0015] This application provides a braking device that is simple in structure, easy to maintain, and safe and effective. By adding a reinforcing part between the limiting part and the supporting part of the braking device, the reinforcing part connects the limiting part and the supporting part respectively, increasing the connection strength between the two. The supporting part is fixed to the ground, thereby improving the structural rigidity of the limiting part. It can effectively limit the protrusions on the brake pad, improve the service life of the limiting part, and reduce the possibility of deformation and cracking of the braking device causing injury to workers.

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 5 As shown, a braking device includes a reinforcing part, which is used to strengthen the connection between the limiting part and the supporting part. A limiting groove is provided below the limiting part so as to cooperate with the protrusion 2 on the brake pad 1 to limit the brake pad 1, thereby preventing the brake pad 1 from moving and achieving braking.

[0025] This application provides a braking device that is simple in structure, easy to maintain, and safe and effective. By adding a reinforcing part between the limiting part and the supporting part of the braking device, the reinforcing part connects the limiting part and the supporting part respectively, increasing the connection strength between the two. The supporting part is fixed to the ground, thereby improving the structural rigidity of the limiting part. It can effectively cooperate with the protrusion 2 on the brake pad 1 to limit it, improve the service life of the limiting part, and reduce the possibility of deformation and cracking of the braking device causing injury to the workers.

[0026] In the braking device of this embodiment, the limiting part is specifically a horizontally arranged upper baffle 3. The upper baffle 3 is arranged perpendicular to the support part and is fixedly connected to the support part. The protrusion 2 abuts against the upper baffle 3 to limit the brake pad 1.

[0027] With the above-mentioned arrangement, the upper baffle 3 extends out of the support surface and approaches the arc-shaped brake pad 1. When the brake pad 1 moves, it drives the protrusion 2 to approach the lower surface of the upper baffle 3 and the bottom end of the upper baffle 3 to limit the movement of the protrusion 2 and the brake pad 1, thereby limiting the movement of the brake pad 1 and preventing the brake pad 1 from moving and causing the brake handle to rebound and injure the staff.

[0028] In the braking device of this embodiment, the support part includes a standing leg 4, the upper end surface of the standing leg 4 is attached to and fixedly connected to the bottom surface of the upper baffle 3, the reinforcing part includes reinforcing plates 5 located on both sides of the standing leg 4, and the limiting groove is located between the two reinforcing plates 5.

[0029] Specifically, the standing leg 4 and the upper baffle 3 are arranged in an L-shape. The right-angled side of the L-shape formed by the standing leg 4 and the upper baffle 3 is connected by a reinforcing plate 5. Compared with not setting the reinforcing plate 5, the connection strength between the upper baffle 3 and the standing leg 4 is greatly increased, thereby improving the upper baffle 3's ability to resist the impact of the protrusion 2 driven by the movement of the brake pad 1, and preventing the upper baffle 3 from deforming or cracking.

[0030] like Figure 1 As shown, the protrusion 2 is specifically a triangular protrusion fixed on the outside of the brake pad 1. When the handle of the brake pad 1 is dragged to bring the two brake pads 1 together to clamp the brake wheel in preparation for braking, the brake pad 1 drives the protrusion 2 to be locked in the limiting groove below the upper baffle 3. The entire braking device limits the protrusion 2 and the brake pad 1, thereby preventing the brake pad 1 from being driven by the inner brake wheel to move or rebound during the braking process.

[0031] In the braking device of this embodiment, the reinforcing plate 5 is a right-angled triangle, and the two right-angled sides of the right-angled triangle are fixedly connected to the upper baffle 3 and the standing leg 4 respectively to strengthen the connection strength between the upper baffle 3 and the standing leg 4.

[0032] By increasing the connection strength between the upper baffle 3 and the standing leg 4 through the above settings, the area of ​​the reinforcing plate 5 is reduced, the processing materials are reduced, and the cost is lowered.

[0033] In the braking device of this embodiment, the width of the standing leg 4 is the same as the width of the upper baffle 3, and the right-angled edge of the triangular surface of the reinforcing plate 5 is fixedly connected to the side of the standing leg 4 and the upper baffle 3 respectively.

[0034] Specifically, the two sides of the upper baffle 3 are flush with the two sides of the standing leg 4. The reinforcing plate 5 is attached to the flat sides of both. The right-angled side of the triangular side is fixedly connected to the flat side of the upper baffle 3 and the standing leg 4 respectively. That is, the right-angled edge of the reinforcing plate 5 is attached to the right-angled edge of the L-shape. The above structure improves the flatness of the braking device and avoids the edge from injuring the palm of the worker during installation.

[0035] Preferably, the upper baffle 3, the standing leg 4, and the reinforcing plate 5 are all made of 45# steel. The dimensions of the standing leg 4 are 15mm×10mm×100mm. The dimensions of the upper baffle 3 are 15mm×50mm×8mm. Two triangular wedges of 50mm×30mm and 5mm thickness are added to the upper baffle 3. The connection between the above structures is all by welding.

[0036] Preferably, the width of the standing leg 4 can be smaller than the width of the upper baffle 3. The standing leg 4 is fixedly connected to the middle of the upper baffle 3. The side of the reinforcing plate 5 is fixedly connected to the side of the standing leg 4. The upper surface of the reinforcing plate 5 is fixedly connected to the bottom surface of the upper baffle 3.

[0037] With the above setup, the two reinforcing plates 5 are clamped on both sides of the standing leg 4 and then welded to the bottom of the upper baffle 3, which can also enhance the connection strength between the standing leg 4 and the upper baffle 3.

[0038] In the braking device of this embodiment, the reinforcing part further includes a connecting plate 6, which is located in the limiting groove. The connecting plate 6 has two sides that are perpendicular to each other, and the two sides are fixedly connected to the surface of the standing leg 4 and the surface of the upper baffle 3, respectively.

[0039] Specifically, the connecting plate 6 is designed to cooperate with the reinforcing plates 5 on both sides to further increase the connection area between the standing leg 4 and the upper baffle 3, thereby enhancing the structural strength of the upper baffle 3 and ensuring effective blocking and limiting of the protrusion 2 on the brake pad 1. Preferably, the connecting plate 6 is also designed as a right-angled triangle.

[0040] In the braking device of this embodiment, the support part further includes a base 7, the standing leg 4 is arranged perpendicular to the base 7, and the base 7 is symmetrically provided with two mounting holes 8 about the standing leg 4. The braking device is fixed to the periphery of the brake pad 1 through the mounting holes 8.

[0041] Specifically, a base 7 is provided to connect the entire braking device to the winch car body, maintain the relative position of the upper baffle 3 and the brake pad 1, and prevent the protrusion 2 from slipping out of the limiting groove. Preferably, the dimensions of the base 7 are 125mm×25mm×8mm, the diameter of the mounting hole 8 is 14mm, the center distance between the two mounting holes 8 is 90mm, and it is installed by bolts.

[0042] In a further preferred embodiment, a partition is provided between the brake pad 1 and the braking device. The shape of the partition matches that of the brake pad 1 and the brake wheel, and it provides a shielding effect for the brake pad 1 and the brake wheel. A braking groove is provided on the partition corresponding to the position of the upper baffle 3 and the protrusion 2, so that the end of the upper baffle 3 can extend into the inner side of the partition and cooperate with the protrusion 2 to limit the brake pad 1 and prevent the brake pad 1 from moving and injuring people.
