Description

Technical Field

[0001] This utility model relates to the field of beam protection technology, specifically to a protective device for structural beams. Background Technology

[0002] Heavy-duty unloading trucks are commonly used equipment in sintering workshops, used for unloading materials from the top of the batching workshop and the top of the finished product bin. Currently, a problem exists during the unloading process of heavy-duty unloading trucks: the material unloaded by these trucks washes against the structural beams of the workshop platform, accelerating beam wear and severely affecting the stability of the plant structure.

[0003] Currently, to protect structural beams, steel plates are laid on top of the beams to protect them, such as... Figure 1 As shown, the existing steel plate protective beam has the following specific structure: the steel plate of the protective beam is in an inverted V shape and welded to the angle steel on both sides of the top of the structural beam to form a casting space. Reinforcing bars are embedded at the top of the structural beam and extend into the casting space. Finally, concrete is poured into the casting space for reinforcement. This steel plate protective beam has the following problems: because the steel plate is fixed and the inclination angle cannot be very large or steep, materials easily stick to and accumulate on the steel plate; in addition, during heavy unloading, the steel plate is subjected to material erosion and wears out quickly, and because the steel plate is fixedly connected, it is inconvenient to disassemble and replace it.

[0004] In conclusion, there is an urgent need for a protective device for structural beams to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for structural beams, aiming to solve the problems of material accumulation and inconvenience in disassembly and replacement of existing protective beams. The specific technical solution is as follows:

[0006] A protective device for a structural beam includes a mounting base, a vertical expansion joint, a protective top plate, protective side plates, and a connecting support. The protective top plate is disposed above the mounting base, and at least one vertical expansion joint is provided between the two. Protective side plates are arranged on both sides of the protective top plate, and the upper side of the protective side plate is rotatably connected to the protective top plate. At least one connecting support is provided between the protective side plate and the mounting base, and the connecting support is rotatably connected to both the protective side plate and the mounting base.

[0007] Preferably, the upper surface of the protective top plate is provided with a baffle plate, and the top surface of the baffle plate has an arc-shaped convex structure.

[0008] Preferably, the protective top plate has hinge grooves at the bottom of both sides, and the upper side of the protective side plate extends into the hinge grooves and is hinged to the protective top plate.

[0009] Preferably, the protective side plate includes a corrugated plate and a wear-resistant plate stacked in layers, wherein the wear-resistant plate is disposed on the upper layer of the corrugated plate.

[0010] Preferably, the connecting support includes a sleeve, a movable rod, and a spring; one end of the movable rod is slidably disposed in the sleeve, and the sleeve is provided with a spring inside, one end of the spring abutting against the bottom of the sleeve, and the other end abutting against the end of the movable rod located in the sleeve.

[0011] Preferably, the mounting base includes locking components and a base body. The base body is an inverted U-shaped structure consisting of a top plate and two side plates. The base body has multiple locking components along the length direction on at least one side plate. The locking components are used to fix the base body to the protected structural beam.

[0012] Preferably, the locking assembly includes a locking bolt and a clamping piece, the side plate is provided with a threaded hole, the locking bolt is disposed through the threaded hole, and the clamping piece is disposed at the end of the locking bolt and located inside the base body.

[0013] Preferably, the locking assembly further includes a locking nut, which is disposed on the locking bolt and used to press against the side plate.

[0014] Preferably, the base body has multiple locking components along the length direction on both side plates, and the locking components on the two side plates are arranged symmetrically.

[0015] Preferably, the base body has multiple locking components along the length direction on one side plate, and an anti-slip pad on the inner side of the other side plate.

[0016] The application of the technical solution of this utility model has the following beneficial effects:

[0017] This utility model, through the cooperation of the base body, locking bolts and clamps, can firmly clamp the base body onto the top of the structural beam, making it convenient to install and fix the protective device on the top surface of the structural beam, and also convenient to disassemble and replace. In use, multiple protective devices can be arranged on the top surface of the structural beam according to the length of the structural beam to complete the protection of the entire structural beam, improving the convenience of use.

[0018] This utility model, through the cooperation of a vertical telescopic component, a protective top plate, a protective side plate, and a connecting support component, can flexibly adjust the tilt angle of the protective side plate. In use, by lifting the protective top plate upwards with the vertical telescopic component, the tilt angle of the protective side plate can be increased, making it easier for materials to slide off the protective side plate and preventing material accumulation. When materials fall onto the protective side plate, due to the buffering effect of the spring in the connecting support component, a certain micro-vibration can be generated, which can not only buffer the impact of materials on the protective side plate, but also allow materials to fall smoothly, improving the stability of the protection device during the unloading process.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0028] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example:

[0031] Figure 1 The structural diagram of the existing protective beam is as follows: The steel plate 9 of the protective beam is in an inverted V shape and welded to the angle steel 7 on both sides of the top of the structural beam 1 to form a casting space. Reinforcing bars 8 are embedded at the top of the structural beam 1 and extend into the casting space. Finally, concrete 10 is poured into the casting space for reinforcement. This steel plate protective beam has the following problems: because the steel plate 9 is fixed and the inclination angle cannot be very large or steep, materials easily stick to and accumulate on the steel plate 9; in addition, during heavy unloading, the steel plate 9 is subjected to rapid wear due to material erosion, and because the steel plate 9 is fixedly connected, it is inconvenient to disassemble and replace it.

[0032] To address the shortcomings of existing protective beam structures, this embodiment provides a protective device for structural beams, such as... Figures 2-6 The protective device includes a mounting base 2, a vertical telescopic member 3, a protective top plate 4, protective side plates 5, and a connecting support member 6. The protective top plate 4 is positioned above the mounting base 2, with at least one vertical telescopic member 3 between them. The vertical telescopic member 3 drives the protective top plate 4 to move vertically. The mounting base 2 is used to fix the protective device onto the structural beam 1 that needs protection. Furthermore, protective side plates 5 are arranged on both sides of the protective top plate 4. The upper side of the protective side plate 5 is rotatably connected to the protective top plate 4. At least one connecting support member 6 is provided between the protective side plate 5 and the mounting base 2. The connecting support member 6 is rotatably connected to both the protective side plate 5 and the mounting base 2. That is, when the protective top plate 4 is driven to move vertically by the vertical telescopic member 3, the two protective side plates 5 will move with the protective top plate 4 (i.e., the tilt angle of the protective side plates can be adjusted). The connecting support member 6 is used to support the lower part of the protective side plates 5, so that the two protective side plates 5 open in a V-shape.

[0033] Preferred, such as Figures 2-4As shown, when there are two or more vertical telescopic members 3 and connecting support members 6, they are all evenly distributed along the length of the protective device.

[0034] Preferably, the vertical telescopic member 3 can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. Meanwhile, as... Figure 2 and Figure 3 As shown, in order to provide good protection for the structural beam 1, the distance between the lower ends of the two protective side plates 5 should be greater than the width of the structural beam 1, so that the protective device can completely cover the structural beam in the width direction of the structural beam and prevent materials from eroding the structural beam.

[0035] Preferably, the upper surface of the protective top plate 4 is provided with a baffle plate 41, the top surface of which is an arc-shaped convex structure. The baffle plate 41 can be installed on the protective top plate 4 by welding or bolting. The baffle plate 41 can provide good protection on the top surface (i.e., the upper surface) of the protective top plate 4, while allowing falling materials to slide off the arc-shaped convex surface, preventing materials from sticking to the baffle plate and accumulating. Further, the baffle plate 41 is preferably made of wear-resistant manganese steel.

[0036] Preferred, such as Figure 5 As shown, the protective side plate 5 includes a corrugated plate 51 and a wear-resistant plate 52 arranged in layers. The wear-resistant plate 52 is disposed on the upper layer of the corrugated plate 51 and can be fixedly connected to the corrugated plate by welding. The connecting support 6 is rotatably connected to the corrugated plate located on the lower layer. Through the supporting and buffering effect of the corrugated plate 51, the impact resistance of the wear-resistant plate 52 is improved, which can effectively cope with the erosion caused by materials during the unloading process and improve its service life. Furthermore, the wear-resistant plate 52 is preferably manganese steel.

[0037] Preferred, such as Figure 6 As shown, the protective top plate 4 is provided with hinge grooves 42 on the bottom of both sides. The upper side of the protective side plate 5 extends into the hinge grooves 42 and is hinged to the protective top plate 4. The advantage of this arrangement is that it can prevent materials from leaking from the joint between the protective top plate 4 and the protective side plate 5 onto the mounting base 2 or accumulating at the joint, and also prevent materials from entering the joint and causing the protective side plate 5 to become stuck.

[0038] See Figure 2 , Figure 3 and Figure 5One end of the connecting support 6 is rotatably connected to the mounting base 2, and the other end is rotatably connected to the protective side plate 5. The connecting support 6 includes a sleeve 61, a movable rod 62, and a spring 63. One end of the movable rod 62 is slidably disposed in the sleeve 61, and the spring 63 is provided inside the sleeve 61. One end of the spring 63 abuts against the bottom of the sleeve 61, and the other end abuts against the end of the movable rod 62 located in the sleeve 61. The length of the connecting support 6 can be changed by sliding the movable rod 62 in the sleeve 61. At the same time, the spring 63 can provide an elastic force to support the movable rod 62. When material falls onto the protective side plate 5, the extension and contraction of the spring can generate a certain micro-vibration, which can not only buffer the impact of the material on the protective side plate 5, but also make the material fall smoothly through vibration, thus improving the stability of the protective device during the unloading process.

[0039] In some embodiments, the connecting support 6 may be a rod of fixed length or a telescopic component of adjustable length (such as a hydraulic cylinder, pneumatic cylinder, or electric cylinder). As long as the connecting support 6 is rotatably connected to the protective side plate 5 and the mounting base 2, the degree of freedom required for the movement of the protective top plate 4 can be satisfied.

[0040] See Figure 2 and Figure 3 The mounting base 2 includes a locking assembly and a base body 21. The base body 21 is an inverted U-shaped structure consisting of a top plate and two side plates. Specifically, the top plate has side plates on both sides, thus forming an inverted U-shaped structure in cross-section. The base body 21 has multiple locking assemblies along the length direction on at least one side plate. The locking assemblies are used to fix the base body 21 to the protected structural beam 1.

[0041] like Figure 3 As shown, the locking assembly includes a locking bolt 22 and a clamping piece 23. A threaded hole is provided on the side plate, through which the locking bolt 22 passes. The clamping piece 23 is disposed at the end of the locking bolt 22 and located inside the base body 21. Preferably, the clamping piece 23 is rotatably disposed at the end of the locking bolt 22. Tightening the locking bolt 22 causes the clamping piece 23 to press against the structural beam 1, thus fixing the protective device to the top of the structural beam. Preferably, in some embodiments, to prevent rigid contact between the clamping piece 23 and the structural beam 1, a flexible pad can be provided on the side of the clamping piece 23 closest to the structural beam (i.e., the side furthest from the locking bolt 22), or the clamping piece 23 can be made of a flexible material, thereby achieving flexible contact between the clamping piece 23 and the structural beam 1 and avoiding scratching the structural beam. Further, the flexible pad and the flexible material can be polyurethane rubber.

[0042] Furthermore, the locking assembly also includes a locking nut 24, which is disposed on the locking bolt 22 and used to hold the side plate in place. After the clamping piece holds the structural beam 1 in place, the locking nut is turned to hold the side plate in place, and a preload is applied through the locking nut 24 to prevent the locking bolt 22 from loosening.

[0043] Preferably, in this embodiment, the base body 21 has multiple locking components along its length on one side plate, and the other side plate of the base body 21 has an anti-slip pad 25 on its inner side, such as... Figure 3 As shown, tightening the locking bolts clamps the structural beam from both sides with the clamping plate 23 and the anti-slip pad 25, thereby achieving the purpose of fixing the protective device. The anti-slip pad 25 can be made of polyurethane rubber, which has good wear resistance and protection.

[0044] In some embodiments, the base body 21 has multiple locking components along its length on both side plates, and the locking components on the two side plates are arranged symmetrically. That is, both sides of the structural beam are held in place by clips 23 to fix the protective device to the structural beam. In this structure, the position of the protective device can be adjusted in the width direction of the structural beam by adjusting the locking bolts 22 on both side plates. Figure 3 Taking the indicated orientation as an example, if the length of the locking bolt on the left side plate screwed into the base body 21 is greater than the length of the locking bolt on the right side plate screwed into the base body, then the overall position of the protective device on the structural beam is to the right; otherwise, the overall position of the protective device on the structural beam is to the left.

[0045] Preferably, the rotational connection in this embodiment refers to a hinged connection. Of course, other forms may be used to achieve rotational connections in the art, which will not be listed in detail in this embodiment.

[0046] The technical solution applied in this embodiment is as follows:

[0047] During installation, multiple mounting bases 2 can be arranged on the top surface of the structural beam 1 according to the length of the structural beam 1 to complete the protection of the entire structural beam 1. Specifically, the base body 21 is firmly clamped to the top of the structural beam 1, and then the locking bolt 22 is tightened so that the clamping piece 23 is clamped on the top side of the structural beam 1, and the locking nut 24 is tightened to make the fixation more secure.

[0048] During unloading, the vertical telescopic member 3 lifts the protective top plate 4 upwards, increasing the tilt angle of the protective side plate 5, making it easier for materials to slide off the protective side plate 5 and preventing material accumulation. When materials fall onto the protective side plate 5, the spring buffering effect of the connecting support member 6 generates a certain amount of micro-vibration, which not only buffers the impact of materials on the protective side plate 5 but also allows the materials to fall smoothly, improving the stability of the protection device during the unloading process. When materials stick to the protective side plate 5, the vertical nerve 3 can move the protective side plate 5 up and down by moving it back and forth, causing the materials to fall off. Therefore, the protection device in this embodiment can not only effectively protect the structural beam 1 during the unloading process but also successfully complete the unloading work.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
