Description

Technical Field

[0001] This utility model relates to the field of braking technology, and more specifically, to a safety fall prevention device. Background Technology

[0002] A board picking warehouse is a physical warehouse and its associated management system specifically designed for storing, managing, and selecting boards (such as engineered wood, solid wood, metal, and composite materials) on demand. Its core function is to respond to production or project orders by efficiently and accurately locating the most suitable boards for outbound processing, serving as a crucial link between inventory and production.

[0003] In existing technologies, there are lifting racks in the picking material warehouse. If the racks do not have anti-fall features, safety accidents are likely to occur. Therefore, we have designed a safety anti-fall device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a fall prevention device that can safely prevent shelves from falling.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A safety fall arrest device includes: a shelf, two braking mechanisms spaced apart vertically and mounted on the shelf, a linkage mechanism mounted on one side of the two braking mechanisms, a speed limiter, a guide wheel mounted above the speed limiter, and a rope connecting the guide wheel and the speed limiter. The braking mechanism includes: Base; Brake blocks are mounted on the base; An eccentric cam is rotatably mounted on the base and located on one side of the brake block, and is used to abut against the brake block after rotation; A fixed base is elastically movable on the base toward the linkage mechanism and fixed to the shelf; The linkage mechanism includes: The adjusting rod is movably connected to two eccentric cams at its upper and lower ends. The pull rod has one end movably connected to the middle of the adjusting rod and the other end fixedly connected to the rope.

[0007] Compared with the prior art, the advantages of this utility model are as follows: During the normal up-and-down movement of the shelving, the eccentric cam separates from the brake block and drives the rope to move up and down, which in turn drives the guide wheel and speed limiter to rotate. When the shelving loses speed, the speed limiter detects the rapid movement of the rope and immediately stops rotating to lock the rope, ensuring that the height of the tie rod fixed on the rope remains unchanged. Due to gravity, the shelving will drive the entire braking mechanism to move downward, which will cause the braking mechanism and linkage mechanism to tilt slightly downward. Since the fixed seat and the base are movable, the entire braking mechanism except for the fixed seat can be moved towards the linkage mechanism, which will cause the eccentric cam to rotate clockwise and lock against the brake block, achieving a safe anti-fall effect for the shelving.

[0008] In some embodiments, the base has two connecting seats at its bottom, a guide rod is provided between the two connecting seats, the fixed seat is movably sleeved on the guide rod, and a spring is provided between the connecting seat on the side away from the linkage mechanism and the fixed seat to provide elastic support.

[0009] In some embodiments, the adjusting rod consists of two rods, upper and lower, which are movably hinged together, and the pull rod is movably connected at the hinge point of the two rods.

[0010] In some embodiments, the linkage mechanism further includes a fixed rod whose bottom end is movably disposed in the middle of the pull rod, and the fixed rod is fixedly disposed on the shelf, and a tension spring is connected to the top end of the fixed rod to the side of the pull rod near the adjusting rod.

[0011] In some embodiments, the safety fall arrestor further includes a frame, on which the shelf is movably mounted vertically; the guide wheels and the speed limiter are both mounted on the frame. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] refer to Figure 1-3 A safety fall arrestor includes: a shelf 1, two braking mechanisms 2 spaced apart and mounted on the shelf 1, a linkage mechanism 3 mounted on one side of the two braking mechanisms 2, a speed limiter 4, a guide wheel 5 mounted above the speed limiter 4, and a rope 6 connecting the guide wheel 5 and the speed limiter 4. The braking mechanism 2 includes: a base 21, a brake block 22, an eccentric cam 23, and a fixed seat 24. The brake block 22 is mounted on the base 21. The eccentric cam 23 is eccentrically rotatably mounted on the base 21 and located on one side of the brake block 22, for rotating and abutting against the brake block 22. The fixed seat 24 is elastically movable on the base 21 toward the linkage mechanism 3 and fixed to the shelf 1. The linkage mechanism 3 includes: an adjusting rod 31 and a pull rod 32. The upper and lower ends of the adjusting rod 31 are movably connected to the two eccentric cams 23. One end of the pull rod 32 is movably connected to the middle of the adjusting rod 31, and the other end is fixedly connected to the rope 6.

[0015] Understandably, shelf 1 is a component used for storing goods in the picking board warehouse; this is existing technology and will not be elaborated upon here. Speed ​​limiter 4 is a component used to limit the speed of the braking rope 6; this is also existing technology and will not be elaborated upon here. The distance between brake block 22 and eccentric cam 23 only needs to ensure that eccentric cam 23 can abut against brake block 22 after rotation. The elastic movable setting of fixed seat 24 can use slide rail guides or shaft hole wires, combined with elastic components such as spring 243, but is not limited to these. Pull rod 32 and rope 6 are fixed, for example, they can be directly bound, bolted, etc., but are not limited to these.

[0016] For reference, please refer to this setting. Figure 3-4During the normal up-and-down movement of the shelf 1, the eccentric cam 23 separates from the brake block 22 and drives the rope 6 to move up and down, which in turn drives the guide wheel 5 and the speed limiter 4 to rotate. When the shelf 1 loses speed, the speed limiter 4 detects the rapid movement of the rope 6 and immediately stops rotating to lock the rope 6, ensuring that the height of the pull rod 32 fixed on the rope 6 remains unchanged. Due to gravity, the shelf 1 will drive the entire braking mechanism 2 to move down, which will cause the braking mechanism 2 and the linkage mechanism 3 to be slightly pulled down and tilted. Since the fixed seat 24 and the base 21 are movable, the entire braking mechanism 2 except for the fixed seat 24 can be moved towards the linkage mechanism 3, which will cause the eccentric cam 23 to rotate clockwise and lock against the brake block 22, achieving the safety anti-fall effect of the shelf 1.

[0017] Optionally, in some embodiments, reference is made to Figure 2 The base 21 has two connecting seats 241 at its bottom, and a guide rod 242 is provided between the two connecting seats 241. The fixed seat 24 is movably sleeved on the guide rod 242. A spring 243 is provided between the connecting seat 241 away from the linkage mechanism 3 and the fixed seat 24. Here, the spring 243 has an elastic opening function, so under normal circumstances, the eccentric cam 23 and the brake block 22 can be separated.

[0018] Optionally, in some embodiments, reference is made to Figure 2-4 The adjusting rod 31 consists of two rods, upper and lower, which are hinged together. The pull rod 32 is movably connected at the hinge point of the two rods. With this configuration, the adjusting rod 31 is no longer a straight rod; its middle part can move to correspond to the rotation of the eccentric cam 23.

[0019] Optionally, in some embodiments, reference is made to Figure 2-4 The linkage mechanism 3 also includes a fixed rod 33, whose bottom end is movably disposed in the middle of the pull rod 32, and the fixed rod 33 is fixedly disposed on the shelf 1. A tension spring 34 is connected to the top end of the fixed rod 33 and the side of the pull rod 32 near the adjusting rod 31. Here, the movable connection between the bottom of the fixed rod 33 and the pull rod 32 can be a hinge, a shaft hole connection, etc. With this configuration, after the brake locks up, the pull rod 32 will be pulled to an angle. Since the fixed rod 33 is fixed to the shelf 1, the fixed rod 33 will remain vertical. After the lifting system of the shelf 1 is repaired, the speed limiter 4 releases the lock on the rope 6, and the tension spring 34 can pull up the pull rod 32 to keep the pull rod 32 horizontal, thereby driving the eccentric cam 23 to rotate and reset, separating it from the brake block 22.

[0020] Optionally, in some embodiments, the safety fall arrestor also includes a frame, on which the shelf 1 is vertically movable; the guide wheels 5 and the speed limiter 4 are both mounted on the frame. Here, the frame is actually a component of the picking material warehouse, providing support for the installation of various components, and is not shown in the accompanying drawings.

[0021] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
