Description

Technical Field

[0001] This utility model relates to the field of conveyor protection technology, specifically a side guardrail for a coal mine belt conveyor. Background Technology

[0002] In coal mine production, belt conveyors are commonly used for transporting coal. However, the side guardrails used in existing belt conveyor equipment are mainly made of side guard steel bars or side guard plates. These side guard steel bars or side guard plates are prone to deformation when impacted by coal, and once deformed, their protective effect is affected. In this case, they need to be replaced in time, resulting in high operating costs in actual application. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a side guardrail for coal mine belt conveyor equipment that is not easily deformed when subjected to coal impact, is not easily replaced, and has low operating costs.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A side guardrail for a coal mine belt conveyor includes positioning seats installed on both sides of the belt conveyor;

[0006] The positioning base is provided with multiple side supports arranged in a linear array on the left and right sides. Each side support is equipped with a side arm with an adjustable tilt angle, and each side arm is equipped with multiple side steel wire ropes in a taut state.

[0007] Multiple tensioning screws are also installed on the side support arm, and each tensioning screw is rotatably mounted with a tensioning frame to adjust the tension of the side wire rope.

[0008] Using the above solution, the side guardrail of the coal mine belt conveyor uses side steel wire rope instead of the side guardrail steel bars or side guard plates in the traditional guardrail. After the side steel wire rope is tightened, based on the characteristics of the steel wire rope itself, the coal will bounce when it hits the side steel wire rope, making the side steel wire rope less likely to deform when it is impacted by the coal. Therefore, it is not easy to replace during use, and its use cost is lower.

[0009] As a preferred embodiment of the side guardrail for a coal mine belt conveyor, multiple linearly arrayed limiting grooves are provided on the side support arm, with the openings of all limiting grooves facing the surface where the belt conveyor is located, and the side wire rope is located inside the limiting groove.

[0010] By adopting the above scheme, in order to better arrange the side wire ropes, the side wire ropes are evenly distributed in the limiting groove. When arranging the side wire ropes, it is only necessary to set them along the limiting groove, which will make the installation more convenient.

[0011] As a preferred embodiment of the side guardrail for a coal mine belt conveyor, the tensioning frame is an E-shaped frame, with the opening direction of the tensioning frame opposite to the opening of the limiting groove, and each tensioning frame simultaneously acts on two adjacent side steel wire ropes.

[0012] Using the above solution, since the side wire rope is prone to loosening when frequently subjected to impacts, the tension can be adjusted by rotating the tensioning screw under the action of the tensioning frame, so that the side wire rope is always taut, thereby better intercepting coal and making it more flexible in application.

[0013] In a preferred embodiment of the side guardrail for a coal mine belt conveyor, the tensioning screw is a butterfly head screw.

[0014] By adopting the above solution, in order to facilitate the rotation of the tensioning screw, the butterfly head nut of the tensioning screw can be rotated easily, which will make the rotation more effortless.

[0015] As a preferred embodiment of the side guardrail of a coal mine belt conveyor, the side support is provided with a positioning hole on the side and the bottom of the side support arm is provided with an angle adjustment hole concentric with the positioning hole. The positioning hole and the angle adjustment hole are both inserted with pins to fix the side support arm.

[0016] Among them, the pin is a flat pin, the positioning hole is a flat hole, and the angle adjustment hole is a star-shaped hole.

[0017] Using the above solution, in order to facilitate the adjustment of the side arm tilt angle, the pin can be removed. After adjusting the side arm tilt angle, the pin can be used to connect the positioning hole and the angle adjustment hole together to complete the side arm tilt angle adjustment, which will make it more flexible in application.

[0018] As a preferred embodiment of the side guardrail of a coal mine belt conveyor, the side support is provided with a plurality of top heads arranged in a circumferential array with positioning holes as the center on the side support arm surface, and the top heads located on both sides of the side support arm are interference fit with the left and right sides of the side support arm.

[0019] By adopting the above scheme, in order to improve the stability of the side arm after it is fixed, the top head is used to abut against the left and right sides of the side arm, so that the side arm will be more stable and reliable after it is fixed.

[0020] After adopting the above technical solution, the beneficial effects of this utility model are:

[0021] 1. The side guardrail of the coal mine belt conveyor uses side steel wire rope instead of the side guardrail steel bars or side guard plates in the traditional guardrail. After the side steel wire rope is tightened, based on the characteristics of the steel wire rope itself, the coal will bounce when it hits the side steel wire rope, making the side steel wire rope less likely to deform when it is impacted by the coal. Therefore, it is not easy to replace during use, and its use cost is lower.

[0022] 2. In order to better arrange the side wire ropes, the side wire ropes are evenly distributed in the limiting groove. When arranging the side wire ropes, it is only necessary to set them along the limiting groove, which will make the installation more convenient.

[0023] 3. Since the side wire rope is prone to loosening when it is frequently impacted, the tension screw can be rotated to adjust the tension of the side wire rope under the action of the tensioning frame, so that the side wire rope is always taut, thereby better intercepting coal and making it more flexible in application.

[0024] 4. To facilitate the rotation of the tensioning screw, simply turn the butterfly nut on the tensioning screw; this will make the tensioning screw easy to turn and require less effort.

[0025] 5. To facilitate the adjustment of the side arm tilt angle, the pin can be removed. After adjusting the side arm tilt angle, use the pin to connect the positioning hole and the angle adjustment hole together to complete the side arm tilt angle adjustment, which will make it more flexible in application.

[0026] 6. To improve the stability of the side arm after it is fixed, a top head is used to press against the left and right sides of the side arm, which will make the side arm more stable and reliable after it is fixed. Attached Figure Description

[0036] 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.

[0037] like Figures 1 to 6 As shown, a side guardrail for a coal mine belt conveyor includes positioning seats 2 installed on both sides of the belt conveyor 1; multiple side supports 3 arranged in a linear array on the positioning seats 2; each side support 3 has an adjustable side arm 4 installed inside; each side arm 4 has multiple taut side steel wire ropes 5 installed on it; multiple tension screws 7 are also installed on the side arm 4, and each tension screw 7 has a tensioning frame 8 rotatably installed to adjust the tension of the side steel wire ropes 5. This side guardrail for the coal mine belt conveyor uses side steel wire ropes 5 instead of the side protective steel bars or side protective plates in traditional guardrails. When the side steel wire ropes 5 are taut, based on the characteristics of the steel wire rope itself, the coal impacting the side steel wire ropes 5 will rebound, making the side steel wire ropes 5 less prone to deformation under the impact of coal. Therefore, it is less likely to be replaced during use, resulting in lower operating costs.

[0038] like Figures 4 to 6 As shown, the side support arm 4 has multiple linearly arrayed limiting grooves 6, all of which face the surface of the belt conveyor 1. The side steel wire ropes 5 are located within the limiting grooves 6. To better arrange the side steel wire ropes 5, they are evenly distributed within the limiting grooves 6. When arranging the side steel wire ropes 5, it is only necessary to set them along the limiting grooves 6, which makes installation more convenient.

[0039] like Figures 4 to 6As shown, the tensioning frame 8 is an E-shaped frame, with its opening direction opposite to that of the limiting groove 6. Each tensioning frame 8 simultaneously acts on two adjacent side steel wire ropes 5. Since the side steel wire ropes 5 are prone to loosening when subjected to frequent impacts, the tension can be adjusted by rotating the tensioning screw 7 under the action of the tensioning frame 8, ensuring that the side steel wire ropes 5 are always taut, thus better intercepting coal and making its application more flexible.

[0040] like Figure 5 As shown, the tensioning screw 7 is a butterfly head screw. To facilitate the rotation of the tensioning screw 7, simply rotate the butterfly head nut of the tensioning screw 7; this will allow the tensioning screw 7 to be rotated easily, requiring less effort during rotation.

[0041] like Figure 7 As shown, a positioning hole 9 is provided on the side of the side bracket 3, and an angle adjustment hole 11 is provided at the bottom of the side support arm 4, which is concentric with the positioning hole. Pins 10 for fixing the side support arm 4 are inserted into both the positioning hole 9 and the angle adjustment hole 11.

[0042] Among them, pin 10 is a flat pin, positioning hole 9 is a flat hole, and angle adjustment hole 11 is a star-shaped hole. In order to facilitate the adjustment of the tilt angle of the side arm 4, pin 10 can be removed. After adjusting the tilt angle of the side arm 4, pin 10 can be used to connect positioning hole 9 and angle adjustment hole 11 together to complete the tilt angle adjustment of the side arm 4, which will make it more flexible in application.

[0043] like Figure 7 As shown, the side bracket 3 has multiple top heads 12 arranged in a circumferential array around the positioning holes 9 on the surface facing the side support arm 4. The top heads 12 on both sides of the side support arm 4 are interference-fitted with the left and right sides of the side support arm 4. In order to improve the stability of the side support arm 4 after it is fixed, the top heads 12 are used to abut against the left and right sides of the side support arm 4, so that the side support arm 4 will be more stable and reliable after it is fixed.

[0044] The working principle of this utility model:

[0045] In application, the coal is transported by the belt conveyor 1. After the side steel wire rope 5 is tightened, based on the characteristics of the steel wire rope itself, if the coal hits the side steel wire rope 5, it will bounce back, making the side steel wire rope 5 less prone to deformation when impacted by the coal. Therefore, it is not easy to replace during use, and its usage cost is low.

[0046] Since the side wire rope 5 is prone to loosening when it is frequently impacted, the tension screw 7 can be rotated to adjust the tension of the side wire rope 5 under the action of the tensioning frame 8, so that the side wire rope 5 is always taut, thereby better intercepting coal.

[0047] If the tilt angle of the side arm 4 needs to be adjusted later, the pin 10 can be removed. After adjusting the tilt angle of the side arm 4, the pin 10 can be used to connect the positioning hole 9 and the angle adjustment hole 11 together to complete the tilt angle adjustment of the side arm 4.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
