Description

Technical Field

[0001] This utility model relates to the field of maintenance technology for underground tunneling equipment in coal mines, and in particular to a quick disassembly device for belt conveyors. Background Technology

[0002] In underground coal mine tunneling faces, belt conveyors are key continuous transportation equipment. As tunneling progresses, the transportation distance often needs to be adjusted, which requires splicing (adding belt) or cutting (removing belt) the belt. One of the core steps in this process is to remove the string that secures the belt buckle so that the belt can be disconnected.

[0003] Currently, the common method used in the industry for removing the belt strip is as follows: one operator uses large pliers (or similar tools) to firmly grip the end of the belt strip, while another operator swings a sledgehammer and repeatedly strikes the pliers, forcibly knocking the belt strip out of the buckle hole through the huge impact force.

[0004] However, this method requires two people to work closely together during operation. The swinging sledgehammer is prone to injuring personnel due to operational errors, tool slippage, or fatigue, which is especially dangerous in the confined space and dimly lit underground environment. Moreover, the impact force is concentrated at the point of application, which can easily cause deformation, splitting, or burr formation at the end of the scissor, rendering the scissor unusable and increasing material consumption costs. At the same time, in the existing technical solutions, the jaws of the shearing pliers are prone to cracking, wear, or deformation when subjected to huge impact forces, resulting in a significantly shortened service life and a high scrap rate. The whole process is time-consuming and labor-intensive.

[0005] Therefore, to address the aforementioned issues, a quick disassembly device for belt strands is proposed. This device replaces the traditional impact-based disassembly process with a T-shaped rotary shearing structure. The strands are spirally extracted from the belt buckle through a rotating operation, requiring only one operator and avoiding the safety risks associated with hammering. The uniform and gentle tension generated by the rotation prevents stress concentration, thus protecting the strands from damage and enabling recycling and reuse. Furthermore, the device is labor-saving, quick, and safe to operate, significantly improving the efficiency and safety of downhole belt installation and removal operations. Utility Model Content

[0006] To overcome the problems of prominent safety hazards, severe damage to the stringers, and low work efficiency when using traditional impact-type stringer disassembly tools in daily use.

[0007] The technical solution of this utility model is: a quick disassembly device for belt strands, comprising: The main component has a T-shaped structure, including a vertically arranged winding rod and a horizontally arranged gripping rod. The winding rod is used to wind and fix the belt string, and the gripping rod is used for the operator to hold and apply rotational torque. A locking structure is provided on the winding rod to releasably lock one end of the belt string, preventing the belt string from slipping out during rotational extraction; The winding rod has a string guide at the end away from the gripping rod, which is used to guide and align the string during initial insertion; The quick-release device for the belt string is configured to: pull the string out of the belt buckle in a spiral manner by rotating it.

[0008] Preferably, the device involves passing the end of the strip slightly through the buckle hole and placing it on the winding rod. The strip is then wound several times around the winding rod for pre-tightening, and its end is inserted into the through hole of the locking structure and locked with a fixing pin. By holding the rod and continuously rotating the device along the spiral direction of the strip, the wound strip, under the fixation of the locking structure and the guidance of the winding rod, generates a continuous and stable axial tensile force. This force acts evenly on the entire strip, smoothly removing it from the buckle hole. This process requires only one person to operate, avoiding the safety risks associated with hammering. The uniform and gentle tensile force generated by rotation avoids stress concentration, thus protecting the strip from damage and enabling recycling and reuse. At the same time, the overall operation of this device is labor-saving, quick, and safe, greatly improving the efficiency and safety of downhole belt adding and removing operations.

[0009] Preferably, the locking structure includes at least a pair of through holes symmetrically arranged in the lower middle part of the winding rod, for inserting a fixing pin or bolt to clamp and fix the end of the string.

[0010] Preferably, the through hole is a circular hole with its axis perpendicular to the axial direction of the winding rod.

[0011] Preferably, the outer surface of the winding rod is provided with anti-slip texture to increase the friction between the winding rod and the string.

[0012] Preferably, the two ends of the grip rod are fitted with anti-slip rubber sleeves, the outer diameter of which is larger than the diameter of the grip rod.

[0013] Preferably, the guide portion of the string is a hemispherical head with an outer diameter less than or equal to the diameter of the string, used for initial insertion into the string hole of the belt buckle.

[0014] Preferably, the main rod is welded from a metal round rod, and its outer surface is coated with an anti-rust coating.

[0015] The beneficial effects of this utility model are: By slightly threading the end of the strip through the buckle hole and placing it on the winding rod, the strip is pre-tightened by wrapping it several times around the winding rod. The end is then inserted into the through hole of the locking structure and locked with a fixing pin. Holding the rod, the device is continuously rotated along the spiral direction of the strip. Under the fixation of the locking structure and the guidance of the winding rod, the wound strip generates a continuous and stable axial tensile force. This force acts evenly on the entire strip, smoothly removing it from the buckle hole. This process requires only one person to operate, avoiding the safety risks associated with hammering. The uniform and gentle tensile force generated by rotation avoids stress concentration, thus protecting the strip from damage and enabling recycling and reuse. Simultaneously, the overall operation of this device is labor-saving, quick, and safe, greatly improving the efficiency and safety of downhole belt application and extraction operations.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 and Figure 2 This utility model provides an embodiment: a quick disassembly device for belt strands, comprising: The main rod has a T-shaped structure, including a vertically arranged winding rod 1 and a horizontally arranged gripping rod 2. The winding rod 1 is used to wind and fix the belt string, and the gripping rod 2 is used for the operator to hold and apply rotational torque. Locking structure 4, provided on winding rod 1, is used to releasably lock one end of the belt string to prevent the belt string from slipping out during rotation and extraction; The winding rod 1 has a string guide 3 at the end away from the holding rod 2, which is used to guide and align the string during initial insertion; The belt puller quick removal device is configured to: pull the puller out of the belt buckle in a spiral manner by rotating it.

[0019] By slightly threading the end of the string through the buckle hole and placing it on the winding rod 1, the string is wound around the winding rod 1 several times to pre-tighten it, and its end is inserted into the through hole 41 of the locking structure 4 and locked with a fixing pin; holding the holding rod 2, the device is continuously rotated in the spiral direction of the string. Under the fixation of the locking structure 4 and the guidance of the winding rod 1, the wound string generates a continuous and stable axial tensile force, which acts evenly on the entire string, and smoothly removes the string from the buckle hole.

[0020] Please see Figure 3 and Figure 4 In this embodiment, the locking structure 4 includes at least a pair of through holes 41, symmetrically arranged in the lower middle part of the winding rod 1, for inserting fixing pins or bolts to clamp and fix the ends of the string strips; by inserting a pin or bolt, the ends of the string strips can be firmly pressed and locked from both sides. This mechanical locking method ensures that the string strips will not slide relative to the device when rotating and applying force, ensuring effective force transmission. At the same time, the locking point area is large, and it is a surface contact rather than a point contact, avoiding stress concentration and preventing indentation or damage to the surface of the string strips; the through holes 41 are circular holes, and their axes are perpendicular to the axial direction of the winding rod 1; the perpendicular hole axis ensures that the direction of the locking force is perpendicular to the axis of the string strips, resulting in a good locking effect; the outer surface of the winding rod 1 is provided with anti-slip texture to increase the friction between the winding rod 1 and the string strips; when the string strips are wound on the winding rod 1, the increased surface friction can help prevent the string strips from slipping in the initial force stage, working in conjunction with the locking structure 4 to make the force transmission more stable and efficient.

[0021] The two ends of the grip rod 2 are fitted with anti-slip rubber sleeves 5, the outer diameter of which is larger than the diameter of the grip rod 2. The anti-slip rubber sleeves 5 greatly increase the grip friction of the operator's hand, so that even in the wet and oily environment downhole, it can be gripped firmly without slipping. The thickened structure makes it more comfortable and effortless for the operator to hold with one hand, making it easier to apply rotational torque, while avoiding hand injuries from prolonged operation. The bar guide part 3 is a hemispherical head, the outer diameter of which is less than or equal to the diameter of the bar, and is used for initial insertion into the bar hole of the belt buckle. When starting the operation, the end of the bar needs to be inserted into the hole of the belt buckle. This hemispherical guide part plays a guiding role, which can guide and align the bar holes with similar diameters, significantly improving the efficiency and accuracy of initial alignment. The main rod is welded from a metal round rod, and its outer surface is coated with an anti-rust coating, ensuring the durability of the device in the wet and harsh environment downhole.

[0022] During operation, the main rod is first welded into a T-shaped structure using metal round rods. The outer surface of the vertical winding rod 1 is processed with anti-slip texture to enhance friction. The two ends of the horizontal gripping rod 2 are fitted with thickened anti-slip rubber sleeves 5 to adapt to the gripping requirements of the wet environment downhole. The top of the winding rod 1 is provided with a hemispherical string guide part 3, the outer diameter of which matches the string diameter to ensure the guiding accuracy when initially inserted into the buckle hole. The locking structure 4 has a pair of through holes 41 symmetrically opened in the lower part of the winding rod 1. The hole axis is perpendicular to the axial direction of the winding rod 1, and the hole diameter is adapted to the fixing pin or bolt. During operation, the operator holds the anti-slip rubber sleeve 5 with one hand, aligns the guide part 3 of the string with the buckle hole, and gently pushes the device to guide the hemispherical head into the hole; after passing the end of the string through the buckle hole slightly, it rests on the winding rod 1 and is wound around the winding rod 1 axially for two to three turns to form a pre-tightening; the end of the string is inserted into the through hole 41 of the locking structure 4, the fixing pin is inserted and locked with a nut to ensure that the end of the string is firmly clamped; The operator rotates the holding rod 2 at a constant speed along the spiral direction of the string. The winding rod 1, through friction and the locking structure 4, works together to convert the rotational torque into a continuous and stable axial tensile force. This tensile force is evenly distributed throughout the string, avoiding stress concentration that could lead to end deformation or splitting, thus achieving a smooth spiral extraction of the string. The entire process requires only one person to operate and is quick.

[0023] Through the above steps, by slightly passing the end of the strip through the buckle hole and placing it on the winding rod 1, the strip is wound around the winding rod 1 several times to pre-tighten it, and its end is inserted into the through hole 41 of the locking structure 4 and locked with a fixing pin; by holding the holding rod 2 and continuously rotating the device along the spiral direction of the strip, the wound strip, under the fixation of the locking structure 4 and the guidance of the winding rod 1, generates a continuous and stable axial tensile force. This force acts evenly on the entire strip, smoothly removing the strip from the buckle hole. This process only requires one person to operate, avoiding the safety risks caused by hammering. The tensile force generated by rotation is uniform and gentle, avoiding stress concentration, thus protecting the strip from damage and enabling recycling and reuse. At the same time, the overall operation of this device is labor-saving, quick, and safe, greatly improving the efficiency and safety of downhole belt adding and removing operations.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
