Technical Field

[0001] This utility model relates to the field of protective device technology, and in particular to a detachable protective railing that works in conjunction with a return material conveyor belt. Background Technology

[0002] In existing crushers, when the return conveyor belt is working, it forms a guardrail to prevent workers from falling off the platform. However, when the return conveyor belt rotates outward, the area above the platform corresponding to the return conveyor belt becomes empty. If someone walks on the maintenance platform at this time, there is a risk of falling. For equipment with safety requirements, this is obviously not in line with installation guidelines, such as safety standards and CE certification standards. Utility Model Content

[0003] To address the above shortcomings, this utility model provides a detachable guardrail that works in conjunction with a return conveyor belt. It can be detachably installed on the platform of the crusher. When the return conveyor belt is in operation, it can be partially removed, and after the return conveyor belt rotates outward, it can be quickly installed on the platform near the edge of the return conveyor belt to achieve protection.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A detachable guardrail that works with a return conveyor belt includes:

[0006] The mounting plate has its bottom mounted on the outside and erected. The top of the mounting plate has multiple vertically opened mounting slots. The upper end of the mounting plate has a notch.

[0007] A vertical rod is mounted on the plate, with its bottom inserted into the mounting slot of the mounting plate and erected vertically.

[0008] External vertical rods, whose bottoms are detachably mounted on the outside and erected vertically;

[0009] A horizontal top rod is horizontally mounted on top of the vertical rods on each of the upper plates and the outer vertical rods, and is detachably connected to the vertical rods on each of the upper plates and the outer vertical rods.

[0010] Furthermore, the top of both the vertical rod on the plate and the outer vertical rod is provided with a top rod mounting groove, and the top vertical rod on the plate and the outer vertical rod are provided with a top through hole that penetrates into the top rod mounting groove at the position corresponding to the top rod mounting groove;

[0011] A through hole is provided at the location where the transverse push rod is placed in the push rod mounting groove;

[0012] Furthermore, when the transverse top rod is placed in the top rod mounting groove, the through hole of the transverse top rod is aligned with the top through hole of the top of the vertical rod on the plate and the top of the outer vertical rod, and a bolt and nut assembly is provided.

[0013] Furthermore, the top through holes of the vertical rods on the plate and the top of the outer vertical rods are horizontally arranged elongated holes.

[0014] Furthermore, it also includes a connecting rod, which is arranged laterally and detachably connected to the external vertical rod and the on-board vertical rod near the external vertical rod.

[0015] Furthermore, the detachable connection between the connecting rod and the vertical rod on the plate and the external vertical rod is a bolt connection.

[0016] Furthermore, a base plate is fixedly installed at the bottom of the outer vertical rod of the plate, and a bottom through hole is opened on the base plate.

[0017] Furthermore, the bottom through hole is an elongated hole.

[0018] Furthermore, the mounting plate has a raised edge on its inner side, and a grid strip is provided on the outer edge of the raised edge at the bottom of the inner side of the mounting plate. The grid strip, the mounting plate, and the raised edge form a space for placing the removed vertical rods on the plate, the outer vertical rods of the plate, and the horizontal top rods.

[0019] Furthermore, the mounting plate is equipped with handrails.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: The detachable guardrail of this utility model, used in conjunction with the return conveyor belt, is applied to the maintenance platform of a crusher. By inserting vertical rods into the mounting plate and installing external vertical rods onto the maintenance platform, and horizontal top rods horizontally supporting the tops of the vertical rods on both the plate and the external vertical rods, an overall guardrail structure is formed. This guardrail structure provides protection, ensuring that pedestrians walking on the platform will not easily fall, thus guaranteeing pedestrian safety and meeting safety standards. When the return conveyor belt is in operation, the horizontal top rods, external vertical rods, and vertical rods on the plate can be removed. At this time, the return conveyor belt will not interfere with the mounting plate when rotating inward, thus not affecting the normal use of the return conveyor belt. The detachable guardrail provided by this utility model can be removed from the platform during operation without affecting the return conveyor belt's work. When the return conveyor belt rotates outward, it can be quickly installed again on the platform near the edge of the return conveyor belt to provide protection and effectively prevent personnel from falling.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figures 1 to 5 A preferred embodiment of this utility model provides a detachable guardrail that works with a return strip. The guardrail mainly includes a mounting plate 10, vertical bars 20 on the plate, vertical bars 30 on the outer side of the plate, a horizontal top bar 50, and a connecting bar 60.

[0032] Mounting plate 10 is a vertically mounted flat structure with a missing corner at its upper end to form a downward-sloping side. This slope corresponds to the slope of the return belt of the crusher. When the return belt is working, the missing corner offsets the plate from the return belt, avoiding interference when the return belt rotates sideways. The bottom of mounting plate 10 is installed onto the maintenance platform of the crusher. It can be fixedly installed, such as by welding it to the maintenance platform, or it can be detachable, such as by bolting it to the maintenance platform.

[0033] The top of the mounting plate 10 is provided with multiple vertically opened mounting slots 11. The depth of the mounting slots 11 is selected according to the height of the vertical rods 20 on the plate. The mounting slots 11 are opened along the top of the mounting plate 10. Due to the notch, some mounting slots 11 are positioned lower. In this case, longer vertical rods 20 are provided on the plate to ensure that when the vertical rods 20 on the plate are placed in the mounting slots 11, the top of the vertical rods 20 on the plate is at the same height.

[0034] In this preferred embodiment, the inner edge of the mounting plate 10 is provided with a raised edge 12, and the top of the raised edge 12 is perforated to form the slot 15 of the mounting groove 11. Multiple ribs 14 are provided on the inner side of the mounting plate 10, and a groove wall of the mounting groove 11 is formed between two ribs 14. The mounting groove 11 structure is formed by the mounting plate 10 and the slot 15, facilitating the vertical insertion of the vertical rod 20 into the mounting groove 11 while ensuring stability. In some preferred embodiments, screw holes are provided at the insertion points of the ribs 14 and the vertical rod 20, allowing the vertical rod 20 to be fixed to the mounting plate 10 by screwing in bolts.

[0035] The bottom of the vertical rod 20 on the plate is inserted into the mounting groove 11 of the mounting plate 10 and erected. The vertical rod 20 on the plate mainly provides heightening protection at the corresponding position of the mounting plate 10.

[0036] The outer vertical bar 30 is detachably mounted on the maintenance platform of the crusher and erected vertically. The detachable mounting is preferably secured with bolts for easy assembly and disassembly. When the outer vertical bar 30 is installed on the maintenance platform, its top is at the same height as the top of the upper vertical bar 20. The outer vertical bar 30 can be configured according to actual conditions; it can be installed at one end of the mounting plate 10 or at both ends. Multiple outer vertical bars 30 can extend along the length or width of the mounting plate 10. The specific configuration mainly considers the protection location, such as the edge of the crusher's maintenance platform.

[0037] The horizontal top rod 50 is horizontally mounted on top of the vertical rods 20 and the outer vertical rods 30 on each plate and is detachably connected to them. When the vertical rods 20 on the plate are inserted into the mounting slots 11 of the mounting plate 10 and the outer vertical rods 30 are installed on the maintenance platform, the horizontal top rod 50 is horizontally mounted on top of the vertical rods 20 and the outer vertical rods 30 on each plate, thus forming the overall structure of the guardrail to achieve protection.

[0038] The guardrail is installed on the maintenance platform of the crusher. Workers often need to climb up or down the maintenance platform. The mounting plate 10 is equipped with a handrail 70 to facilitate workers' climbing.

[0039] In practice, when the return conveyor belt is not in operation, its outward rotation leaves the area above the platform corresponding to the return conveyor belt unoccupied. At this time, by inserting the vertical rods 20 on the plate into the mounting slots 11 of the mounting plate 10, and installing the outer vertical rods 30 onto the maintenance platform, and horizontal top rods 50 horizontally mounted on top of the vertical rods 20 and 30 on each plate, a protective railing structure is formed. This railing structure provides protection, ensuring that pedestrians will not easily fall off the platform, thus guaranteeing their safety and meeting safety standards. When the return conveyor belt is in operation, the horizontal top rods 50 are removed from the tops of the vertical rods 20 and 30 on the plate, then the vertical rods 20 on the plate are removed from the mounting plate 10, and then the outer vertical rods 30 are removed from the maintenance platform. At this time, the mounting plate 10 can be installed on the maintenance platform. When the return conveyor belt rotates inward, it will not interfere with the mounting plate 10, thus not affecting the normal use of the return conveyor belt. The detachable guardrail provided by this utility model can be removed from the platform during operation without affecting the operation of the return conveyor belt. When the return conveyor belt is rotated outward, it can be quickly installed on the edge of the platform near the return conveyor belt to achieve protection and effectively prevent personnel from falling.

[0040] In a preferred embodiment, both the top of the vertical rod 20 on the upper plate and the outer vertical rod 30 are provided with a top rod mounting groove. The vertical rod 20 on the upper plate and the outer vertical rod 30 have top through holes 51 penetrating into the top rod mounting groove at their corresponding positions. The transverse top rod 50 has a through hole at the position where it rests in the top rod mounting groove, so that when the transverse top rod 50 is placed in the top rod mounting groove, the through hole of the transverse top rod 50 is aligned with the top through holes 51 of the top of the vertical rod 20 on the upper plate and the outer vertical rod 30, and a bolt and nut assembly (not shown in the figure) is provided. The top rod mounting groove allows for partial radial positioning of the transverse top rod 50 by the vertical rod 20 on the upper plate and the outer vertical rod 30, and the bolt and nut assembly, passing through the top through hole 51 of the top rod mounting groove and the through hole of the transverse top rod 50, locks the transverse top rod 50 in place, ensuring its secure protection. The transverse top rod 50 can be a single piece or multiple pieces. When multiple pieces are used, they should be installed end-to-end or connected as much as possible. When there is a bend, the transverse top rod 50 should have a corresponding bend at the bend. In this exemplary embodiment, the top of the vertical rod 20 on the plate and the outer vertical rod 30 on the plate are respectively fixedly provided with mounting groove side plates 52 at opposite side positions. The two oppositely arranged mounting groove side plates 52 form a top rod mounting groove, and the top through hole 51 is opened on the mounting groove side plate 52. It is understood that the two oppositely arranged mounting groove side plates 52 should not be in the direction of extension of the transverse top rod 50 to avoid interference with the transverse top rod 50. At this time, the space between the two oppositely arranged mounting groove side plates 52 is sufficient for the transverse top rod 50 to enter. The distance between the two oppositely arranged mounting groove side plates 52 (the groove width of the top rod mounting groove) is equal to the outer diameter of the transverse top rod 50, so that the transverse top rod 50 will not wobble due to obvious gaps after entering the top rod mounting groove. The top through holes 51 of the vertical rod 20 on the plate and the outer vertical rod 30 on the plate are horizontally arranged elongated holes to accommodate a certain degree of error. This ensures that when the horizontal push rod 50 is placed in the push rod mounting groove and has a slight axial misalignment or when there is a machining error in the through hole of the horizontal push rod 50, the top through hole 51 is aligned with the through hole of the horizontal push rod 50, so that the bolt and nut assembly can be inserted and locked.

[0041] The detachable guardrail, which works in conjunction with the return strip, also includes a connecting rod 60. The connecting rod 60 is horizontally positioned and detachably connected to the outer vertical bar 30 and the upper vertical bar 20 adjacent to the outer vertical bar 30. The connecting rod 60 is installed at the middle position of the outer vertical bar 30 to enhance the stability of the guardrail. The detachable connection between the connecting rod 60 and the upper vertical bar 20 and outer vertical bar 30 is a bolt connection. Corresponding screw holes are provided on the connecting rod 60, the upper vertical bar 20, and the outer vertical bar 30. Bolts are screwed into these holes for temporary locking, facilitating both assembly and disassembly.

[0042] A base plate 31 is fixedly installed at the bottom of the outer vertical rod 30. The base plate 31 has a bottom through hole 32. The base plate 31 increases the contact area with the maintenance platform, making the outer vertical rod 30 more stable and less prone to wobbling. Furthermore, by providing the base plate 31 and the bottom through hole 32, and corresponding screw holes on the maintenance platform, quick and easy disassembly and installation can be achieved using bolts. The bottom through hole 32 is an elongated hole, increasing tolerance for errors. This allows for adjustment of the position of the base plate 31 to adjust the outer vertical rod 30, ensuring it can be tightened onto the maintenance platform with bolts. This facilitates assembly with the upper vertical rod 20, connecting rod 60, and transverse top rod 50, etc.

[0043] The mounting plate 10 has a raised edge 12 on its inner side edge. A grid strip 13 is provided on the outer edge of the raised edge 12 at the bottom of the inner side of the mounting plate 10. The grid strip 13, the mounting plate 10, and the raised edge 12 form a space for placing the removed vertical rods 20, outer vertical rods 30, and horizontal top rods 50 on the plate. After the vertical rods 20, outer vertical rods 30, horizontal top rods 50, and connecting rods 60 are removed, they can be temporarily placed in the space formed by the grid strip 13, the mounting plate 10, and the raised edge 12, which facilitates the storage of the vertical rods 20, outer vertical rods 30, horizontal top rods 50, and connecting rods 60.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
