Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an elevator material guiding device with a wear-resistant plate. Background Art

[0002] The elevator is a device used to vertically lift bulk and granular materials such as limestone, coal, gypsum, clinker, dry clay, etc. that have passed through the crusher. According to the speed of the hopper, the elevator can be divided into three types: centrifugal discharge, gravity discharge and mixed discharge. The bucket speed of centrifugal discharge is relatively fast, which is suitable for conveying powdery, granular and other low-abrasive materials; the bucket speed of gravity discharge is relatively slow, which is suitable for conveying bulk, high-density, and highly abrasive limestone and clinker materials. The traction components of the elevator include ring chain, plate chain and belt. The structure and manufacturing of the ring chain are relatively simple. When conveying highly abrasive materials, the chain wears less, but its dead weight is relatively large. However, the elevator of the prior art is easily worn by hard materials at the outlet of the three-way section of the discharge, and because the inner side of the outlet is worn and concave, not only is the discharge resistance large, but it is also easy to cause the discharge powder to leak out, resulting in a high dust concentration, affecting the sanitary environment of the section.

[0003] The Chinese patent document with the publication number CN217321948U discloses a conveniently replaced hoist wear plate, including a lower wear plate, the top of the lower wear plate is fixedly connected with a side wear plate, the top of the side wear plate is provided with a slide groove, the inner cavity of the slide groove is provided with a reinforcing plate, the top of the reinforcing plate is fixedly connected with an upper wear plate, the front of the upper wear plate is fixed with a connecting plate, and the back of the connecting plate is fixedly connected with a fixing plate. The conveniently replaced hoist wear plate, through the coordinated use of the upper wear plate, the lower wear plate, the side wear plate, the fixing plate, and the second fixing plate, the upper wear plate, the lower wear plate, and the side wear plate are fixed to the discharge port housing by using the second fixing plates on the left and right sides of the fixing plate. When the material comes out of the discharge port, the material pressure on the discharge port housing will act on the lower wear plate, the upper wear plate, and the reinforcing plate, thereby avoiding direct contact between the material and the discharge port housing, causing excessive wear of the discharge port housing, thereby improving the service life of the hoist.

[0004] During use, the wear-resistant plate is covered by the transported materials most of the time and is located inside the machine head. Therefore, it is not easy to observe the wear of the wear-resistant plate. As a result, it often happens that the wear-resistant plate is worn through and the discharge port of the elevator is worn. The discharge port is difficult to manufacture, assemble and replace. Therefore, the wear-resistant plate should be replaced in time after it is worn to prevent the discharge port from being worn. Utility Model Content

[0005] In order to overcome the technical problem in the prior art that the wear-resistant plate of the elevator discharge port is located inside the head and the surface is covered by the transported material, resulting in difficulty in observing the wear condition; one purpose of the utility model is to provide an elevator material guiding device with a wear-resistant plate, by embedding a sliding plate at the lower end of the wear-resistant plate, and arranging a counterweight block transmission-connected to the lower end of the sliding plate below the discharge port; after the wear-resistant plate and the sliding plate are successively worn through, the counterweight block slides down and then plays an indicating role.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a hoist material guiding device with a wear-resistant plate, comprising a support plate, the support plate is arranged in a discharge port, and the lower end of the support plate is inclined below the discharge port; a first wear-resistant plate, the first wear-resistant plate is arranged at the upper end of the support plate; a mounting shell, the mounting shell is arranged below the support plate; a wire rope, the wire rope is arranged in the mounting shell and has a deformable redundant length; a counterweight block, the counterweight block is longitudinally slidably connected to the bottom of the mounting shell, and the upper end of the counterweight block is arranged on the wire rope; a first sliding plate, the first sliding plate has a plurality of them, the first sliding plate is slidably connected to the lower end of the first wear-resistant plate, and the sliding direction of the first sliding plate is arranged along the inclination direction of the support plate; wherein, the upper end of the first sliding plate is fixedly connected to the upper end of the first wear-resistant plate, and the lower end of the first sliding plate is fixedly connected to the wire rope.

[0007] When the material transported by the elevator enters the discharge port, it dumps onto the upper end of the first wear-resistant plate. Due to the impact caused by gravity, the middle part of the first wear-resistant plate will be more seriously worn. When the middle part of the first sliding plate breaks due to wear, the steel wire rope slides downward under the pull of the counterweight block, and then the wear condition of the first wear-resistant plate can be intuitively understood.

[0008] Since the material will be unevenly distributed during the lifting process, the wear of the first wear-resistant plate will also be uneven. Multiple first sliding plates are evenly dispersed at the lower end of the first wear-resistant plate. After each first sliding plate is worn off, it will cause the same counterweight block to slide down, and the indication position is more concentrated, which is convenient for observation.

[0009] Furthermore, a second wear-resistant plate is provided at the lower end of the first wear-resistant plate; a plurality of second sliding plates are slidably connected to the lower end of the second wear-resistant plate; the upper end of the second sliding plate is fixedly connected to the upper end of the second wear-resistant plate, and the lower end of the second sliding plate is fixedly connected to the steel wire rope; the sliding distance of the counterweight block pulled by a single second sliding plate is greater than the sliding distance of the counterweight block pulled by all the first sliding plates.

[0010] When the first sliding plate breaks and causes the counterweight block to slide down, the second wear-resistant plate acts as a buffer to prevent the discharge port from being worn, and it is also convenient to adjust the production plan and prepare to replace the first wear-resistant plate; in addition, when all the first sliding plates are worn and broken, or any of the second sliding plates are worn and broken, the counterweight block will slide to the lowest position, and the machine must be stopped immediately to replace the first wear-resistant plate and the second wear-resistant plate.

[0011] Specifically, the thickness of the first wear-resistant plate is greater than the thickness of the second wear-resistant plate; the thickness of the second wear-resistant plate is greater than the thickness of the second sliding plate.

[0012] Furthermore, the steel wire ropes are connected end to end to form a closed rectangle; a first hook is provided at the lower end of the first sliding plate; a second hook is provided at the lower end of the second sliding plate; the first hook is hung on the upper part of the rectangle, and the second hook is hung on the lower part of the rectangle.

[0013] When the first wear-resistant plate, the first sliding plate, the second wear-resistant plate, and the second sliding plate are replaced, the first hook and the second hook are easy to disassemble and reinstall, which simplifies the replacement steps and improves work efficiency.

[0014] Specifically, a plurality of pairs of guide rope wheels are arranged in the installation shell; the first pull hook is arranged in the middle of each pair of corresponding guide rope wheels; and the second pull hook is arranged on one side of each pair of corresponding guide rope wheels.

[0015] The deformation length of the steel wire rope caused by the second hook is greater than the deformation length of the steel wire rope caused by the first hook, thereby being able to reduce the volume of the installation housing.

[0016] Preferably, the upper ends of the first wear-resistant plate and the second wear-resistant plate are respectively provided with hanging plates bent downward; the hanging plates abut against the upper ends of the supporting plates.

[0017] The first wear-resistant plate and the second wear-resistant plate are subjected to downward sliding pulling force while being subjected to wear. The folding plate and the upper end of the support plate abut against each other, thereby reducing the shear stress borne by the mounting screws and thereby improving the mounting strength.

[0018] Preferably, a sensor is provided between the counterweight block and the mounting housing; the sensor is used to monitor the sliding distance of the counterweight block.

[0019] Preferably, the lower end of the mounting shell is provided with an indication port slidably connected to the counterweight block; and the outer wall of the counterweight block is provided with an indication marking line.

[0020] The sensor can record and monitor the wear condition more intuitively and accurately; the sliding distance of the counterweight block is also convenient for direct visual observation.

[0021] Specifically, the upper end of the mounting shell is rotatably connected to two rope guide shafts.

[0022] Specifically, a core plate is arranged in the installation shell; a first bending plate bent upward is arranged on the side of the core plate close to the elevator; a second bending plate bent downward is arranged on the side of the core plate away from the elevator; the upper and lower parts of the rectangle are respectively located above and below the core plate.

[0023] The core plate separates the first hook and the second hook to prevent the first hook and the second hook from being entangled after the first sliding plate is broken, that is, to prevent the second hook from being stuck.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. Wear-resistant plates are set to prevent the transported materials from directly wearing the discharge port. The wear-resistant plates have the advantages of low manufacturing cost and easy replacement compared to the discharge port, which increases the service life of the discharge port;

[0026] 2. By setting the sliding plate and the counterweight, the sliding plate will break due to wear, causing the counterweight to slide downward, thereby indicating the wear of the wear-resistant plate. When the wear-resistant plate is completely worn out, it can be discovered and replaced in time to prevent the transported materials from further wearing toward the discharge port.

[0027] 3. By arranging the first wear-resistant plate and the second wear-resistant plate in layers, when the first wear-resistant plate is completely worn out or the second wear-resistant plate is worn out, the counterweight block will slide to the same designated position, which is convenient for detecting the wear condition of the first wear-resistant plate and the second wear-resistant plate, and can also help to prepare for production planning and replacement in advance.
