Description

Technical Field

[0001] The present invention relates to the field of mining machinery and equipment and the field of mechatronic monitoring technology, and in particular to a separation detection sensor wire pulley assembly and a use method thereof. Background Art

[0002] The mine tunnel roof separation monitoring device is mainly used for coal mine tunnel roof and surrounding rock deep loosening and separation monitoring, and can also be used for other similar structures of culverts, civil air defense project roof collapse risk monitoring. The separation detection device can generally detect the separation displacement of two points near and far. The near measuring point and the far measuring point are often several meters, more than ten meters or even farther apart. The distance between them needs to be transmitted by wire rope, and this certain length of wire rope needs to be stored in the spare wire wheel group. In view of the use requirements of the detection device, it is necessary to equip the wire reel and wire payout wheel group to meet the use of different scenarios near and far. Less wire is paid out at the near measuring point, and more wire is paid out at the far measuring point.

[0003] Common roof separation monitoring devices are usually equipped with spare wire reels, with a separate spare wire reel for each near and far measuring point. Since the spare wire reel is not part of the main body of the monitoring device, it is often easily overlooked, and a simple spare wire reel or a small box is used instead. This spare wire reel design is too simple, with only two parts, the wheel shell and the wheel axle, which are connected by snaps when in use, and the cable is passed inside. Such a structure will lead to the following problems:

[0004] (1) The reel has no locking device, and the reeling and releasing of the line cannot be controlled;

[0005] (2) The structure is too simple, and the plastic buckle is almost a one-time installation and cannot be removed;

[0006] (3) Poor reliability. In actual use, the wire rope is prone to loose retraction, resulting in the backup line being either too long or too short, affecting normal use;

[0007] (4) Structural jamming. During use, the internal rotating mechanism is prone to friction jamming and is not smooth. Summary of the invention

[0042] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the terms "front", "rear", "inside", "outside", "right", "left", "both ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] like Figure 1-6 As shown, the present invention provides a separation detection sensor wire reel assembly, comprising: an end cover 1, a hand screw 2, a winding wheel 3, a rolling bearing 4, a main housing 5, a spring 6 and a locking member 7.

[0046] like Figure 1 As shown, the end cover 1 is used for the overall end face limit installation and is fixed to one end of the main shell 5 with screws and other fixings; the hand screw 2 is used for locking and loosening to realize the functions of winding and releasing the line; the winding wheel 3 is used for winding and has a paddle structure; the rolling bearing 4 is used to reduce friction resistance and smooth rolling; the main shell 5 is the outermost structure of the entire spare line wheel group, and is provided with a buckle for locking the hand screw 2 and the winding wheel 3; the spring 6 is used to provide restoring force; the locking piece 7 is used to lock the hand screw 2 at the end, and is used for installation and disassembly, and is fixed with screws.

[0047] like Figure 2 As shown, in actual application, the locking piece 7 is pressed and the hand knob 2 is rotated to a relaxed state, the paddle 22 of the hand knob 2 disengages from the buckle of the winding wheel 3 and is stuck in the shallow groove of the main shell 5, unlocking the winding wheel 3 so that the winding wheel 3 can rotate forward and reverse to realize the line-reeling and line-releasing functions; the rolling bearing 4 is nested between the main shell 5 and the winding wheel 3 to realize smooth rolling and prevent jamming, thereby realizing smooth line-reeling and line-releasing functions.

[0048] like Figure 3 As shown, the main shell 5 is designed with a deep slot 51 and a shallow slot 52. The deep slot 51 is a locking slot, and the shallow slot 52 is a releasing slot. The hand screw 2 is provided with a paddle 22, and the paddle 22 can be inserted into the deep slot 51 or the shallow slot 52 of the main shell 5. The winding wheel 3 is provided with evenly distributed short cards 31, which are slightly lower than the shallow slot 52 and higher than the deep slot 51; when the paddle 22 of the hand screw 2 rotates into the deep slot 51, the paddle 22 of the hand screw 2 will be stuck, thereby blocking the short card 22 of the winding wheel 3, causing the winding wheel 3 to be unable to rotate, that is, the positioning and locking of the winding wheel 3 can be achieved. The winding wheel 3 is provided inside the main shell 5; the hand screw 2 is provided inside the groove column 54;

[0049] like Figure 4When the paddle 22 of the hand-twisted wire 2 rotates to the shallow groove 52, the paddle 22 of the hand-twisted wire 2 will also be stuck. Due to the height difference between the shallow groove 52 and the short card 31 of the winding wheel 3, the paddle 22 of the hand-twisted wire 2 cannot cover the short card 31 of the winding wheel 3, and the winding wheel 3 can rotate, that is, the winding wheel 3 can be relaxed.

[0050] In this way, the locking and loosening of the spare wire wheel can be achieved through the mutual cooperation of the deep clamping groove 51, the shallow clamping groove 52, the paddle 22 and the short clamping groove 31.

[0051] like Figure 6 As shown, the end cover 1 is used for sealing and positioning the overall structure. A limiting hole 11 is formed through the center of the end cover 1, and screw holes 12 are formed evenly along the circumference of the outer side of the limiting hole 11. Screws pass through the screw holes 12 to fasten the main housing 5 and the end cover 1 to form a rope holding area 32; the end surface is used to position and limit the winding wheel 3.

[0052] like Figure 5 As shown, a hand screw 21 is provided at the upper end of the hand screw 2 for finger operation and rotation; a paddle 22 is provided at the lower side of the contact surface for cooperating with the main housing 5 to achieve locking and loosening. A threaded hole 23 is provided at the tail of the hand screw 2 for fixing the locking member 7, and the middle section is used to install the spring 6.

[0053] like Figure 7 As shown, the winding wheel 3 is a hollow structure, and the cavity is used to accommodate the hand screw 2 and the rolling bearing 4. The whole is fixed by the end face and the end cover 1. The upper end face of the winding wheel 3 is provided with uniformly distributed short cards 31, and the overall height of the short cards 31 is lower than the shallow card groove 52 of the main shell 5, and higher than the deep card groove 51. An end face of the winding wheel 3 is provided with an outwardly extending handle 33, which is used to rotate the winding wheel 3 to realize the retracting and releasing functions. The bottom surface of the other end face of the winding wheel 3 is provided with a threading hole 34 for fixing the running rope.

[0054] The rolling bearing 4 is installed between the main housing 5 and the winding wheel 3, and its main function is to ensure smooth rotation and prevent jamming during rotation.

[0055] like Figure 8 As shown, the main housing 5 is the main body of the wire reel. The outer ring is provided with a wire outlet groove 53 for passing the wire rope; a slot column 54 is provided in the middle, and a deep card groove 51 and a shallow card groove 52 are provided on one end face of the slot column 54, the deep card groove 51 is used for locking, and the shallow card groove 52 is used for loosening; the outer surface of the main body is printed to increase the friction resistance, and an embedded nut is used to tighten the end cover.

[0056] The spring 6 is installed between the hand screw 2 and the locking member 7, and is integrally inserted into the spring cavity 55 of the main housing 5, so as to provide a restoring force to ensure that the hand screw 2 will not fall out of the deep slot 51 when not operated by humans.

[0057] like Fig. 9As shown, the locking member 7 is installed on the back of the main shell 5 and is fixed to the hand screw 2 by a fastening screw 72; the locking member 7 is completely hidden in the main shell 5 in any state to prevent the hand screw 2 from being accidentally touched and triggered; a hexagonal slot 71 is left in the middle of the locking member 7, which can be adjusted with a hexagonal wrench.

[0058] Its principle and working process are:

[0059] In the initial state, the paddle 22 on the hand screw 2 is stuck in the deep card slot 51 of the main housing 5, and the paddle 22 will block the short card of the winding wheel 3, causing the winding wheel 3 to be unable to rotate, and the winding and releasing functions cannot be realized; when the locking member 7 is pressed, the spring 6 is compressed to make the paddle 22 of the hand screw 2 disengage from the card slot area of ​​the main housing 5, and the hand screw 2 is rotated to make the paddle 22 slide into the shallow card slot 52. Due to the height difference between the short card 31 of the winding wheel 3 and the paddle 22 on the hand screw 2, the paddle 22 cannot block the winding wheel 3, and the winding wheel 3 can rotate freely, thereby realizing the winding and releasing functions. The spring 6 is used to generate a restoring force. When no pressing force is applied, the restoring force of the spring 6 can ensure that the hand screw 2 is in close contact with the main housing 5 and will not loosen, thereby ensuring the normal use of the winding and releasing functions.

[0060] The present application also includes a method for using a separation detection sensor spare wheel assembly, comprising the following steps:

[0061] S1, inserting the paddle 22 into the deep slot 51 for locking;

[0062] S1.1. Screw the paddle 22 on the hand screw 2 to the position of the deep slot 51 of the main housing 5, and insert the paddle 22 into the deep slot 51;

[0063] S2, inserting the plectrum 22 into the shallow slot 52 for collecting and releasing the line;

[0064] S2.1. Press the locking member 7 to squeeze the paddle 22 on the hand screw 2 out of the deep slot 51.

[0065] S2.2, rotate the paddle 22 on the hand screw 2 to the position of the shallow slot 52 of the main housing 5, and insert the paddle 22 into the shallow slot 52;

[0066] S2.3, rotating the handle 33, so that the winding wheel 3 rotates, so as to realize the line reeling and releasing.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
