Description

Technical Field

[0001] This application relates to the field of underground pipeline installation technology in coal mines, and in particular to a traction structure for underground pipeline installation. Background Technology

[0002] During coal mine construction, it is common to encounter situations where underground pipelines are installed on the side walls of coal mine tunnels. When moving these underground pipelines to their installation locations within the coal mine tunnels, a traction mechanism is required.

[0003] The current traction mechanism for installing underground pipelines in coal mines mainly consists of a base plate, a base mounted on the upper side of the base plate, and a winch body mounted on the base plate. When tractioning and transporting underground pipelines in coal mines, the traction mechanism is first fixed in the corresponding position in the coal mine tunnel. Then, the underground pipeline is placed on a mobile trolley. Next, the traction rope on the winch body is connected to the mobile trolley for placing the underground pipeline. During the winding process of the traction rope on the winch body, the underground pipeline can be moved and transported into the coal mine tunnel along with the corresponding mobile trolley, so as to facilitate the convenient installation of underground pipelines in the coal mine tunnel.

[0004] While existing traction mechanisms for underground pipeline installation in coal mines can facilitate the transfer and installation of underground pipelines within the mine tunnels, the traction rope sways as the pipeline moves, causing wear on its surface during winding on the winch. Prolonged wear reduces the rope's tensile strength, posing a risk of breakage and failure, thus compromising the safety of the traction mechanism during underground pipeline installation. Furthermore, the installation of the winch base on the mounting plate is cumbersome, primarily achieved by individually screwing on the winch, resulting in low installation efficiency and hindering efficient traction of underground pipelines. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this application is to provide a traction structure for downhole pipeline installation that can both clamp and limit the traction rope during downhole pipeline traction to prevent the traction rope from swinging back and forth relative to the drum surface on the winch body during winding, and achieve quick connection and limitation between the base on the winch body and the mounting plate through a linkage quick lock, thereby facilitating efficient traction of downhole pipelines.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A traction structure for installing downhole pipelines includes a mounting base. A mounting groove is formed on one side of the upper end of the mounting base. A base is installed within the mounting groove, and a winch body is mounted on the top of the base. A bracket is mounted on the mounting base on the traction side of the winch body. A clamping and limiting mechanism is mounted on the bracket. A quick-release mechanism is also installed between the base and the mounting groove. The clamping and limiting mechanism includes a guide wheel, a clamping plate, a T-shaped groove, a T-shaped slider, a double-acting screw, and a drive motor. The T-shaped groove is formed in the middle of the top end of the bracket. The double-acting screw is installed in the middle of the T-shaped groove, and the drive motor is connected to the double-acting screw. At one end of the rod, there are two T-shaped sliders, and the two T-shaped sliders are symmetrically installed on two threaded sections with opposite directions of rotation on the bidirectional lead screw. The clamping plate is connected to the middle of the bottom end of the T-shaped slider, and the guide wheel is installed at the clamping part at the bottom end of the clamping plate. The quick-release mechanism includes a limiting post, a limiting hole, a linkage plate, a screw, a dual-axis motor, and a sliding cavity. The dual-axis motor is installed in the middle of the base, and the screw is installed on the two power output ends of the dual-axis motor. Each screw is equipped with a linkage plate, and the limiting post is connected to the side of the linkage plate facing away from the dual-axis motor. The sliding cavity is reserved in the base at the location of the linkage plate.

[0008] Optionally, the bracket has an inverted U-shaped structure, and the bottom end of the bracket is bolted to the mounting base plate.

[0009] Optionally, the T-shaped slider slides into the T-shaped cavity, and the T-shaped slider is welded and fixed to the upper side of the clamping plate.

[0010] Optionally, the bidirectional lead screw passes through the T-shaped slider and is threadedly connected to the T-shaped slider. The bidirectional lead screw is connected to the drive motor coupling, and the drive motor is bolted to the outer wall of the bracket.

[0011] Optionally, the guide wheel is rotatably connected to the clamping plate, and the outer wall of the guide wheel has a concave annular structure in the middle.

[0014] Optionally, the linkage plate slides with the sliding cavity, and the limiting post is welded and fixed to the linkage plate.

[0015] Optionally, the vertical cross-sectional dimensions of the limiting post are matched with the vertical cross-sectional dimensions of the limiting hole.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention utilizes a mounting bracket on the traction side of the winch body on a mounting base plate. A clamping and limiting mechanism, consisting of a guide wheel, clamping plate, T-shaped groove, T-shaped slider, bidirectional screw, and drive motor, is installed on the bracket. This mechanism limits the movement of underground pipelines during installation and traction, preventing the traction rope from repeatedly swinging on the surface of the winch drum, reducing wear, and mitigating the risk of breakage during prolonged use. This enhances safety during underground pipeline installation and traction. Furthermore, a quick-installation mechanism is installed between the base on the lower side of the winch body and the mounting groove on the mounting base plate. This mechanism allows the limiting pin to be quickly inserted into the limiting hole while the screw shaft rotates driven by the dual-axis motor, enabling rapid installation and limiting of the winch body on the mounting base plate. This facilitates efficient traction of underground pipelines during installation in coal mine tunnels. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the existing traction mechanism for underground pipeline installation in coal mine construction will first be introduced.

[0026] The existing traction mechanism for installing underground pipelines in coal mines mainly consists of a base plate, a base mounted on the upper side of the base plate, and a winch body mounted on the base plate. When tractioning and transferring underground pipelines in coal mines, the traction mechanism is first fixed in the corresponding position in the coal mine tunnel. Then, the underground pipeline is placed on a mobile trolley. Next, the traction rope on the winch body is connected to the mobile trolley for placing the underground pipeline. During the winding process of the traction rope on the winch body, the underground pipeline can be moved and transferred into the coal mine tunnel along with the corresponding mobile trolley, so as to facilitate the convenient installation of underground pipelines in the coal mine tunnel.

[0027] Please see Figures 1-4 This application discloses a traction structure for installing downhole pipelines, comprising a mounting base 2, an mounting groove 5 on one side of the upper end of the mounting base 2, a base 3 installed in the mounting groove 5, a winch body 1 installed on the top of the base 3, a bracket 4 installed on the mounting base 2 on the traction side of the winch body 1, a clamping and limiting mechanism 6 installed on the bracket 4, and a quick-release mechanism 7 installed between the base 3 and the mounting groove 5. The clamping and limiting mechanism 6 includes a guide wheel 61, a clamping plate 62, a T-shaped slide 63, a T-shaped slider 64, a double-acting screw 65, and a drive motor 66. The T-shaped slide 63 is located in the middle of the top end of the bracket 4, the double-acting screw 65 is installed in the middle of the T-shaped slide 63, and the drive motor 66 is connected to the double-acting screw 65. Two T-shaped sliders 64 are mounted on one end of the lead screw 65, and the two T-shaped sliders 64 are symmetrically installed on the two threaded sections of the bidirectional lead screw 65 with opposite directions of rotation. The clamping plate 62 is connected to the middle of the bottom end of the T-shaped slider 64, and the guide wheel 61 is installed at the clamping part at the bottom end of the clamping plate 62. The quick-release mechanism 7 includes a limiting post 71, a limiting hole 72, a linkage plate 73, a screw 74, a dual-axis motor 75, and a sliding cavity 76. The dual-axis motor 75 is installed in the middle of the base 3, and the screw 74 is installed on the two power output ends of the dual-axis motor 75. Each screw 74 is equipped with a linkage plate 73. The linkage plate 73 is connected to the limiting post 71 on the side facing away from the dual-axis motor 75. A sliding cavity 76 is reserved in the base 3 at the linkage plate 73.

[0028] Specifically, during the installation of underground pipelines in a coal mine, the base 3 on the winch body 1 is first placed in the installation slot 5. Then, under the action of the dual-shaft motor 75, the screw 74 is rotated. After the screw 74 rotates, the linkage plate 73 moves along the sliding cavity 76 under the action of the threaded transmission. After the linkage plate 73 moves, it inserts the limiting post 71 into the limiting hole 72. Thus, the base 3 is quickly limited and installed under the action of the limiting post 71 and the limiting hole 72. Next, the traction rope on the winch body 1 is connected to the underground pipeline moving trolley in the coal mine tunnel. The traction rope is clamped and limited under the action of the clamping plate 62 and the guide wheel 61 in the clamping and limiting mechanism 6. Finally, the winch body 1 is started, and the underground pipeline installation moving trolley is pulled by the traction rope under the action of the winch body 1 to facilitate the convenient transfer of the underground pipeline to the installation position on the side wall of the mine tunnel during installation.

[0029] Please see Figures 1-3 The bracket 4 has an inverted U-shaped structure, and the bottom end of the bracket 4 is bolted to the mounting base plate 2.

[0030] As one implementation method, the welding-fixed connection method makes the bracket 4 more securely installed, and the bracket 4 is mainly used to provide an installation base for the clamping and limiting mechanism 6.

[0031] Please see Figure 2 and Figure 5 The T-shaped slider 64 slides with the T-shaped cavity 76, and the T-shaped slider 64 is welded and fixed to the upper side of the clamping plate 62.

[0032] In one implementation, the T-shaped slider 64 provides a mounting base for the clamping plate 62, and also enables convenient movement and adjustment of the clamping plate 62 along the direction of the T-shaped slide groove 63.

[0033] Please see Figure 3 The bidirectional lead screw 65 passes through the T-shaped slider 64 and is threadedly connected to the T-shaped slider 64. The bidirectional lead screw 65 is connected to the drive motor 66 via a coupling. The drive motor 66 is bolted to the outer wall of the bracket 4.

[0034] In one implementation, after the drive motor 66 drives the bidirectional lead screw 65 to rotate, the two T-shaped sliders 64 will move closer together under the action of thread transmission, thereby causing the two clamping plates 62 to move closer together to both sides of the traction rope on the winch body 1.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The guide wheel 61 is rotatably connected to the clamping plate 62, and the middle part of the outer wall of the guide wheel 61 is a concave annular structure.

[0036] As one implementation method, the outer wall of the guide wheel 61 is made into a concave annular structure in the middle, which can ensure that the guide wheel 61 makes rapid contact with the traction rope on the winch body 1.

[0037] Please see Figure 4 The base 3 has a hollow structure located at the dual-axis motor 75, and the dual-axis motor 75 is connected to the screw 74 via a coupling.

[0038] As one implementation method, the hollow structure design of the base 3 provides sufficient installation space for the dual-axis motor 75.

[0039] Please see Figure 4 The screw 74 is rotatably connected to the base 3, and the screw 74 passes through the linkage plate 73 and is threadedly connected to the linkage plate 73.

[0040] In one implementation, after the screw 74 rotates, it will cause the linkage plate 73 to move along the slide cavity 76 under the action of the threaded transmission, thereby realizing the synchronous movement of the limit post 71.

[0041] Please see Figure 4 The linkage plate 73 and the sliding cavity 76 are in sliding fit, and the limiting post 71 is welded and fixed to the linkage plate 73.

[0042] As one implementation method, the sliding fit installation method makes the sliding of the linkage plate 73 relative to the sliding cavity 76 more stable.

[0043] Please see Figure 4 The vertical cross-sectional dimensions of the limiting post 71 match the vertical cross-sectional dimensions of the limiting hole 72.

[0044] As one implementation method, matching the vertical cross-sectional dimensions of the limiting post 71 with the vertical cross-sectional dimensions of the limiting hole can ensure convenient insertion of the limiting post 71 into the limiting hole 72.

[0045] The specific working principle is as follows: When installing underground pipelines in a coal mine, the base 3 on the winch body 1 is first placed in the installation slot 5. Then, under the action of the dual-shaft motor 75, the screw 74 rotates. After the screw 74 rotates, the linkage plate 73 moves along the sliding cavity 76 under the action of the threaded transmission. After the linkage plate 73 moves, it inserts the limiting post 71 into the limiting hole 72, so that the base 3 is quickly limited and installed under the action of the limiting post 71 and the limiting hole 72. Next, the traction rope on the winch body 1 is connected to the underground pipeline moving trolley in the coal mine tunnel, and the traction rope is clamped and limited under the action of the clamping plate 62 and the guide wheel 61 in the clamping and limiting mechanism 6. Finally, the winch body 1 is started, and the underground pipeline installation moving trolley is pulled by the traction rope under the action of the winch body 1, so as to facilitate the installation of the underground pipeline on the side wall of the mine tunnel. The traction structure facilitates convenient transportation. It not only clamps and limits the traction rope on the winch body 1 under the clamping action of the clamping plate 62 and guide wheel 61 in the clamping and limiting mechanism 6, preventing the traction rope from swinging back and forth on the drum surface of the winch body 1, reducing wear on the traction rope, and avoiding the risk of breakage and failure of the traction rope on the winch body 1 during long-term use, thus improving the safety of underground pipeline installation traction, but also allows for the installation of a quick-installation mechanism 7 between the base 3 on the lower side of the winch body 1 and the mounting groove 5 on the mounting base plate 2. This mechanism enables the limiting post 71 to be quickly inserted into the limiting hole 72 while the dual-axis motor 75 in the quick-installation mechanism 7 drives the screw 74 shaft to rotate, thereby achieving rapid installation and limiting of the winch body 1 on the mounting base plate 2, facilitating efficient traction of underground pipelines during installation in coal mine tunnels.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
