Description

Technical Field

[0001] This utility model relates to the field of installation mechanism technology, specifically to a sensor installation mechanism for protecting runaway vehicles in mine inclined shafts. Background Technology

[0002] In the actual application of the mine inclined shaft runaway protection device for the winch, in order to determine the forward and reverse rotation of the motor and the position of the hoisting gate, it is necessary to provide corresponding signals to the main control box through sensors. The roller is a rotating body, and the position overlaps during the rotation process, so the signal needs to be calculated by the PLC of the main control box.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: Although the existing sensor installation mechanism for mine inclined shaft runaway protection has the function of disassembly and assembly, since the sensors are installed in batches and there is a need for repositioning and adjustment later, disassembly and assembly are time-consuming and laborious, and urgently need to be improved. Therefore, we propose a sensor installation mechanism for mine inclined shaft runaway protection. Utility Model Content

[0004] The purpose of this utility model is to provide a sensor installation mechanism for protecting runaway vehicles in mine inclined shafts, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sensor installation mechanism for the protection of trolley cars in a mine inclined shaft, including a track, wherein a limit block is placed in the middle of the track, and there are two sets of limit blocks;

[0006] A gripping rod is fixedly installed between the two sets of limiting blocks. An assembly groove is provided on the upper surface of the gripping rod, and a proximity sensor is fixedly installed in the assembly groove.

[0007] A groove is provided on one side of the inner wall of the limiting block. A limiting plate is movably positioned in the groove, and an anti-slip pad is fixedly installed on the outer wall of the limiting plate. An anti-detachment block is fixedly installed at the bottom of the limiting plate. An inner rod is fixedly installed at the bottom of the inner side of the limiting plate, and a spring is sleeved on the outer side of the inner rod.

[0008] The inner rod moves through the side wall of the limiting block. Both sets of inner rods have pull rings fixedly installed at their inner ends, and steel wire ropes are wound and fixed on the pull rings. A rubber sleeve is fixedly fitted on the outer side of the middle part of the steel wire rope.

[0009] The track is fixedly installed with several sets of uniformly arrayed crossbeams, and the limiting block is sleeved on the outside of the crossbeams.

[0010] Both ends of the grip are fixedly equipped with locking blocks, which are inserted into preset slots within the limiting block. This can be achieved through the use of components such as a wire rope, spring, and limiting plate. When used in the protective sensor installation mechanism, the grip is held, with fingers placed under the rubber sleeve of the wire rope. Applying force upwards with the fingers compresses the wire rope, causing the inner rod to move inwards and retract the limiting plate into its slot. The limiting block then fits onto the crossbeam of the track. Releasing the wire rope allows the spring tension, combined with the anti-slip pad, to fix the mechanism to the crossbeam. This structural design facilitates easy assembly and disassembly, making batch installation more efficient and allowing for easy repositioning and adjustment later.

[0011] As an optional solution to the technical solution of this application, support plates are fixedly installed on both sides of the bottom of the grip rod. A screw is screwed into the middle of the support plate through a screw hole. The screw is rotatably connected to the limiting block through a bearing. It can be used in conjunction with components such as screw and locking block. By rotating the screw, the screw can drive the limiting blocks on both sides to move outward, thereby adjusting the distance between the two sets of limiting blocks. This makes it suitable for crossbeams with various spacings, with strong versatility and ideal performance.

[0012] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on one side of the handle, and the indicator sign is fixed by welding. The indicator sign can introduce the usage method, making it easy for beginners to use, and can also remind them of relevant precautions.

[0013] As an optional solution to the technical solution of this application, a protrusion is fixedly installed on the top of the inner rod, and the protrusion abuts against one side of the limiting block. The inner rod can be limited by the protrusion, which meets the usage requirements.

[0014] As an optional solution to the technical solution of this application, the two ends of the spring are fixedly connected to the limiting plate and the limiting block respectively. The fixed connection of the two ends of the spring can prevent the spring from slipping off at both ends during the extension and retraction, and avoid frequent reinstallation of the component.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a sensor installation mechanism for the protection of trolley cars in a mine inclined shaft. The mechanism includes a wire rope, a spring, and a limiting plate. When in use, the sensor installation mechanism is operated by gripping the handle and placing the fingers under the rubber sleeve of the wire rope. Applying force upwards with the fingers compresses the wire rope, causing the inner rod to move inwards and the limiting plate to retract into the groove. The limiting plate then fits onto the crossbeam of the track. Releasing the wire rope allows the spring tension, combined with the anti-slip pad, to fix the mechanism to the crossbeam, with the anti-detachment block positioned under the crossbeam. This structural design facilitates easy assembly and disassembly, making batch installation more efficient and allowing for easy repositioning and adjustment later.

[0017] 2. This utility model discloses a sensor installation mechanism for protecting runaway vehicles in a mine inclined shaft. By setting a screw and a locking block, the screw can be rotated to move the limiting blocks on both sides outward, thereby adjusting the spacing between the two sets of limiting blocks. It is suitable for crossbeams with various spacings, has strong versatility, and has a relatively ideal effect. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3This utility model provides a technical solution: a sensor installation mechanism for the protection of a trolley in a mine inclined shaft, including a track 1, with a limiting block 3 placed in the middle of the track 1, and there are two sets of limiting blocks 3; a handle 2 is fixedly installed between the two sets of limiting blocks 3, and an indicator sign 23 is fixedly installed on one side of the handle 2, and the indicator sign 23 is fixed by welding. The indicator sign 23 can introduce the usage method, making it easy for first-time users to use, and can also remind them of relevant precautions. An assembly groove is opened on the upper surface of the handle 2, and a proximity sensor 21 is fixedly installed in the assembly groove; a plate groove 32 is opened on the inner wall of one side of the limiting block 3, and a limiting plate 4 is movably locked in the plate groove 32. An anti-slip pad 41 is fixedly installed on the outer wall of the limiting plate 4. An anti-detachment block 48 is fixedly installed at the bottom of the limiting plate 4, and an inner rod 42 is fixedly installed on the bottom inner side of the limiting plate 4. A sleeve is fitted on the outer side of the inner rod 42. A spring 43 is provided, with its two ends fixedly connected to the limiting plate 4 and the limiting block 3, respectively. The fixed connection of the two ends of the spring 43 can prevent the spring 43 from slipping off at both ends during extension and retraction, thus avoiding frequent reinstallation of the component. The inner rod 42 moves through the side wall of the limiting block 3. Pull rings 46 are fixedly installed at the inner ends of both sets of inner rods 42, and steel wire ropes 44 are wound and fixedly fixed on the pull rings 46. A rubber sleeve 45 is fixedly fitted on the outer side of the middle part of the steel wire rope 44. A protrusion 47 is fixedly installed on the top of the inner rod 42, and the protrusion 47 abuts against one side of the limiting block 3. The protrusion 47 can block and thus limit the inner rod 42, which meets the usage requirements. Several sets of evenly arrayed crossbeams 11 are fixedly installed in the track 1, and the limiting block 3 is fitted on the outer side of the crossbeams 11. The two ends of the grip 2 are fixedly installed with locking blocks 22, and the locking blocks 22 are inserted into the preset locking slots 31 in the limiting block 3.

[0025] In this technical solution, components such as wire rope 44, spring 43, and limiting plate 4 can be used together. When using the protective sensor installation mechanism, the gripping rod 2 can be held, and the fingers can be placed under the rubber sleeve 45 of the wire rope 44. Then, the wire rope 44 can be squeezed upward by applying force with the fingers. The inner rod 42 will be moved inward by the force, causing the limiting plate 4 to retract into the plate groove 32. Then, the limiting block 3 will be fitted onto the crossbeam of the track. Then, the wire rope 44 can be released, and the tension of the spring 43, together with the anti-slip pad 41, will fix the mechanism on the crossbeam 11, and the anti-detachment block 48 will be located under the crossbeam. This structural design is easy to disassemble and assemble, making batch installation more efficient and facilitating subsequent repositioning and adjustment.

[0026] In some technical solutions, support plates 5 are fixedly installed on both sides of the bottom of the grip 2. A screw rod 51 is screwed into the middle of the support plate 5 through a screw hole. The screw rod 51 is rotatably connected to the limit block 3 through a bearing 52.

[0027] In this technical solution, components such as screw 51 and locking block 22 can be used together. By rotating screw 51, the limiting blocks 3 on both sides can be moved outward, thereby adjusting the spacing between the two sets of limiting blocks 3. This makes it suitable for crossbeams 11 with various spacings, with strong versatility and ideal performance.

[0028] Working principle: It should be noted that this utility model is a sensor installation mechanism for the protection of runaway vehicles in a mine inclined shaft. All components are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When using a sensor installation mechanism for protecting runaway vehicles in a mine inclined shaft, the sensor installation mechanism is transported to the runaway vehicle area of ​​the mine inclined shaft. Then, the sensor assembly for protection is installed on the designated track by the installation mechanism, and the sensor is connected to the external protection system. During this process, the vehicle body can be detected by the sensor.

[0030] By incorporating a wire rope 44, a spring 43, and a limiting plate 4, the protective sensor installation mechanism can be used by gripping the handle 2 and placing the fingers under the rubber sleeve 45 of the wire rope 44. Applying force upwards with the fingers compresses the wire rope 44, causing the inner rod 42 to move inwards, retracting the limiting plate 4 into the groove 32. This allows the limiting block 3 to be fitted onto the crossbeam of the track. Releasing the wire rope 44 then allows the spring 43, in conjunction with the anti-slip pad 41, to fix the mechanism onto the crossbeam 11, with the anti-detachment block 48 positioned under the crossbeam. This design facilitates easy assembly and disassembly, making batch installation more efficient and allowing for easy repositioning and adjustment later. The screw 51 and locking block 22 allow for adjustment of the spacing between the two sets of limiting blocks 3 by rotating the screw 51, enabling the adjustment of the spacing between the two sets of limiting blocks 3. This makes it suitable for crossbeams 11 with various spacings, offering strong versatility and ideal performance.
