Description

Technical Field

[0001] This utility model relates to the field of temperature sensing cable fixing technology, and in particular to a fixing device for temperature sensing cables in raw coal bunkers. Background Technology

[0002] The raw coal bunker is enormous, storing tens of thousands of tons of coal. The coal particles are hard and have sharp edges, resulting in significant impacts, pulling, friction, and wear during the processes of feeding, piling, and removing coal. Traditional heat-sensing cables, secured with simple cable ties or clips, are easily torn or worn through, causing the fire monitoring system to malfunction. Therefore, a new securing device for heat-sensing cables in raw coal bunkers needs to be designed.

[0003] To address this, patent CN211790467U discloses a fixing device for communication cables, including a mounting plate with mounting holes on its surface. A support plate is fixedly mounted on one side of the mounting plate, and a threaded rod is rotatably connected between the two support plates. A turntable is fixedly connected to one end of the threaded rod, and a first connecting block is threadedly connected to the surface of the threaded rod. This invention rotates the turntable to drive the threaded rod to rotate. Because the threads on both sides of the threaded rod are in opposite directions, the threaded rod drives the two first connecting blocks threadedly connected to it to move towards each other, thereby driving the first clamp and the second clamp to move towards each other, achieving adjustment of the positions of the first clamp and the second clamp. By setting a connecting cylinder, baffle, connecting rod, first spring, limit block, and pull ring on the second connecting block, and using the through groove and limit groove opened on the surface of the third connecting block, it is convenient to open or close the two second connecting blocks, achieving fixation of the two clamps and improving the stability of the device.

[0004] Although the aforementioned cable fixing device can facilitate the stability of the cable fixing and lifting device during use, the cable and fixing device are exposed to the air during use and are easily damaged by impact. Therefore, it is necessary to design a fixing device for temperature sensing cables in raw coal bunkers. Utility Model Content

[0005] The purpose of this utility model is to provide a fixing device for temperature sensing cables in raw coal bunkers, in order to solve the defect that existing fixing devices for temperature sensing cables in raw coal bunkers are exposed to air during use and are easily damaged by impact.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fixing device for a temperature sensing cable in a raw coal bunker, including the coal bunker wall;

[0007] A temperature-sensing cable body is provided on the inner side of the coal bunker wall, and an installation structure is uniformly provided on the outer side of the temperature-sensing cable body.

[0008] A protective structure is uniformly fixed on the inner wall of the outer coal bunker wall of the installation structure. The protective structure includes a protective end plate, a fixing bolt, and a protective side plate. The protective side plates are uniformly arranged on the outer side of the installation structure. Both ends of the protective side plates are fixed with protective end plates, and the interior of each protective end plate is penetrated by a fixing bolt.

[0009] The installation structure has pre-positioning structures evenly arranged on the side near the coal bunker wall.

[0010] Furthermore, the installation structure includes a mounting base, a protective inner pad, a limiting bolt, and a protective pad. The mounting base is evenly distributed on the outside of the temperature sensing cable body. Limiting bolts pass through both sides of the inside of the mounting base. A protective inner pad is provided on the inner side of the bottom of the mounting base. A protective pad is fixed on the side of the mounting base near the coal bunker wall.

[0011] Furthermore, the inner wall of the protective pad and the outer side of the temperature sensing cable body abut against each other, and the mounting bases are evenly distributed on the outer side of the temperature sensing cable body.

[0012] Furthermore, one end of each limiting bolt passes through the protective pad and extends into the interior of the coal bunker wall.

[0013] Furthermore, the protective end plates are symmetrically distributed on both sides of the protective side plates, and the protective side plates are evenly distributed on the outer side of the temperature sensing cable body.

[0014] Furthermore, one end of each fixing bolt extends into the interior of the coal bunker wall.

[0015] Furthermore, the pre-positioning structure includes a positioning shaft, a guide groove, and a positioning groove. The positioning groove is evenly opened inside the coal bunker walls on both sides of the temperature sensing cable body. The guide groove is evenly opened inside the coal bunker wall at the end of the positioning groove near the temperature sensing cable body. The positioning shaft is evenly fixed to the side of the mounting base near the coal bunker wall.

[0016] Furthermore, the positioning shaft and the coal bunker wall are connected by an interference fit through a positioning groove.

[0017] The present invention provides a fixing device for a temperature-sensing cable in a raw coal bunker, the advantages of which are:

[0018] By incorporating a protective structure, the protective side plates are evenly distributed on the outside of the installation structure, forming an additional physical barrier that can directly resist lateral impacts and friction from the flow of raw coal, protecting the internal installation structure and the temperature-sensing cable body from frontal damage. The protective side plates are stably connected to the inner wall of the coal bunker through the protective end plates and fixing bolts at both ends, forming a robust frame structure. This greatly enhances the overall integrity and deformation resistance of the entire fixing device, enabling the device to easily protect the temperature-sensing cable body and installation structure, and improving the applicability and safety of the fixing device for the temperature-sensing cable in the raw coal bunker during use.

[0019] By incorporating an installation structure and using limit bolts to firmly anchor the mounting base to the coal bunker wall, the main mechanical connection for fixing the temperature-sensing cable body is provided, ensuring the stability of the entire fixing device under the impact and vibration of coal flow. The inner wall of the protective pad directly contacts the outer wall of the temperature-sensing cable body. The protective pad is made of elastic, wear-resistant, and insulating rubber, which can effectively buffer mechanical impact, prevent wear and cuts to the temperature-sensing cable body, and extend the service life of the temperature-sensing cable body. The mounting bases are evenly distributed on the outside of the temperature-sensing cable, so that the temperature-sensing cable body is subjected to uniform force during installation, avoiding damage caused by local stress concentration. The protective pad is placed between the mounting base and the coal bunker wall, which can play a role in shock absorption and parallelism adjustment, while preventing direct friction between the mounting base and the coal bunker wall. This realizes the function of facilitating stable installation of the temperature-sensing cable body and improves the stability of the fixing device for temperature-sensing cables in the raw coal bunker during use.

[0020] By incorporating a pre-positioning structure, before tightening the limiting bolts and fixing bolts, the positioning shaft and the coal bunker wall are tightly connected via an interference fit through the positioning groove. This allows for rapid pre-alignment and temporary fixing of the mounting base and its components in the designed position, greatly facilitating installation. This is particularly advantageous when working in high-altitude, narrow, or dimly lit coal bunkers. During bolt tightening, the pre-positioning structure prevents the entire device from shifting due to gravity or operational errors, ensuring installation accuracy and efficiency. This design enables rapid positioning of the installation structure, improving the convenience and efficiency of the coal bunker temperature-sensing cable fixing device. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1-5 The present invention provides a fixing device for a temperature sensing cable in a raw coal bunker, comprising a coal bunker wall 1.

[0029] Reference Figures 2-4 A temperature-sensing cable body 2 is provided on the inner side of the coal bunker wall 1. An installation structure 3 is evenly provided on the outer side of the temperature-sensing cable body 2. The installation structure 3 includes a mounting base 31, a protective inner pad 32, a limiting bolt 33, and a protective pad 34. The mounting base 31 is evenly provided on the outer side of the temperature-sensing cable body 2. The limiting bolt 33 passes through both sides of the inner side of the mounting base 31. The inner side of the bottom of the mounting base 31 is provided with a protective inner pad 32. The side of the mounting base 31 closest to the coal bunker wall 1 is fixed with a protective pad 34. The inner wall of the protective inner pad 32 and the outer side of the temperature-sensing cable body 2 abut against each other. The mounting bases 31 are evenly distributed on the outer side of the temperature-sensing cable body 2. One end of the limiting bolt 33 passes through the protective pad 34 and extends into the interior of the coal bunker wall 1.

[0030] The mounting base 31 is snapped onto the outside of the temperature sensing cable body 2. Then, the mounting base 31 and the temperature sensing cable body 2 are pre-fixed to the inner wall of the coal bunker wall 1 through the pre-positioning structure 5. Then, the limiting bolt 33 passes through both sides of the mounting base 31 and the protective pad 34, and finally screws into the threaded hole pre-embedded in the coal bunker wall 1, thereby firmly fixing the mounting structure 3 to the inner wall of the coal bunker wall 1, forming the main fixing point for the temperature sensing cable body 2.

[0031] Reference Figures 1-5A protective structure 4 is uniformly fixed on the inner wall of the outer coal bunker wall 1 of the installation structure 3. The protective structure 4 includes a protective end plate 41, a fixing bolt 42 and a protective side plate 43. The protective side plates 43 are uniformly arranged on the outer side of the installation structure 3. The protective end plates 41 are fixed at both ends of the protective side plates 43. The fixing bolts 42 penetrate through the interior of the protective end plates 41. The protective end plates 41 are symmetrically distributed on both sides of the protective side plates 43. The protective side plates 43 are evenly distributed on the outer side of the temperature sensing cable body 2. One end of the fixing bolts 42 extends into the interior of the coal bunker wall 1.

[0032] The protective side plate 43 is arranged parallel to the temperature sensing cable body 2 and covers the outside of multiple mounting seats 31. The protective end plate 41 is located at both ends of the protective side plate 43 and is penetrated and anchored to the inner wall of the coal bunker wall 1 by the fixing bolt 42. The force from the coal block first acts on the solid protective side plate 43, and its energy is dispersed and transferred to the solid bunker wall through the protective end plate 41 and the fixing bolt 42, thereby avoiding the force from acting directly on the mounting seat 31 and the temperature sensing cable body 2.

[0033] Reference Figures 2-5 The installation structure 3 is evenly provided with a pre-positioning structure 5 on the side near the coal bunker wall 1. The pre-positioning structure 5 includes a positioning shaft 51, a guide groove 52 and a positioning groove 53. The positioning groove 53 is evenly opened inside the coal bunker wall 1 on both sides of the temperature sensing cable body 2. The positioning groove 53 is evenly opened inside the coal bunker wall 1 at the end of the coal bunker wall 1 near the temperature sensing cable body 2. The positioning shaft 51 is evenly fixed to the side of the mounting base 31 near the coal bunker wall 1. The positioning shaft 51 and the coal bunker wall 1 are connected by interference fit through the positioning groove 53.

[0034] A positioning groove 53 and a guide groove 52 connected to it are pre-cut on the coal bunker wall 1. During installation, the positioning shaft 51 on the mounting base 31 is first aligned with the guide groove 52 and inserted. Then, it is slid along the guide groove 52 until the positioning shaft 51 is finally inserted into the positioning groove 53. Since the positioning shaft 51 and the coal bunker wall 1 are interference-fitted through the positioning groove 53, the positioning shaft 51 will be tightly locked inside the positioning groove 53, thereby achieving temporary fixation of the mounting base 31. After that, the worker can free up his hands to safely and accurately carry out subsequent drilling and tightening of the limit bolt 33.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
