Description

Technical Field

[0001] This utility model belongs to the field of monkey car installation technology, specifically relating to a windproof and shock-absorbing monkey car anti-detachment structure for mining. Background Technology

[0002] In existing technology, mining passenger cars (aerial passenger transport devices) are typically fixed to steel wire ropes via a gripper and supported by a pulley. However, the traditional gripper structure has the following problems: First, the gripper and steel wire rope are fixed by only a single clamping mechanism, lacking secondary protection measures. Once the gripper's clamping force decreases due to vibration, impact, or long-term wear, it is prone to rope slippage, posing a significant safety hazard. Second, when the gripper passes the pulley, due to the relative movement between the steel wire rope and the pulley, as well as external wind force and vibration, the gripper is easily subjected to lateral compression or misalignment impact, leading to reduced clamping stability with the steel wire rope, or even direct detachment from the running track. Therefore, this utility model proposes a windproof and shock-absorbing anti-detachment structure for mining passenger cars to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a windproof and shock-absorbing anti-detachment structure for mining trolleys, which can solve the above-mentioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows: This utility model provides a windproof and shock-absorbing anti-detachment structure for a mining hoist, including a cable gripper, a tripping and limiting mechanism, a steel wire rope, and a rope-supporting wheel. The cable gripper is installed on the steel wire rope, the steel wire rope is draped on the rope-supporting wheel, the tripping and limiting mechanism is set on the cable gripper and is in an inner sleeve state with the steel wire rope, and the tripping and limiting mechanism is movable and coordinated with the rope-supporting wheel. The tripping and limiting mechanism includes a first side plate, a second side plate, and fastening bolts. The first side plate and the second side plate are provided with symmetrical insertion parts, and the two insertion parts are inserted into the two sides of the horizontal plate on the cable gripper. The first side plate and the second side plate are fastened to the cable gripper by two sets of fastening bolts. The upper side of the first side plate and the second side plate is provided with an insertion mechanism and a suspension mechanism. The lower side of the second side plate is provided with an elastic swing mechanism that cooperates with the suspension mechanism. A rubber roller is provided on the side of the rope-supporting wheel. The roller rolls with the side of the rope-supporting wheel and is installed on the lower side of the suspension mechanism.

[0005] Preferably, the interlocking mechanism includes an interlocking plate and a sleeve frame. The interlocking plate and the sleeve frame are interlocked. The interlocking plate is fixed on the upper side of the second side plate. The sleeve frame is fixed on one side of the bottom surface of the fixing plate. The other side of the fixing plate is fixed on the upper side of the first side plate.

[0006] Preferably, the suspension mechanism includes a support plate and a lower extension plate. The lower extension plate is symmetrically distributed with the wire rope as the center and the cable gripper. The lower extension plate is fixed on one side of the support plate. The support plate is located above the position where the cable gripper is installed on the wire rope and is fixed on a fixed plate. A bow support plate for reinforcing the support plate is fixed on the fixed plate.

[0007] Preferably, the roller is disposed on the bottom surface of the lower extension plate and rotatably mounted on the vertical plate, and the vertical plate is vertically mounted on the lower side of the lower extension plate.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1-6 As shown, a windproof and shock-absorbing anti-detachment structure for a mining hoist includes a cable gripper 1, a tripping and limiting mechanism 2, a steel wire rope 3, and a rope-supporting wheel 4. The cable gripper 1 is installed on the steel wire rope 3, the steel wire rope 3 is draped on the rope-supporting wheel 4, the tripping and limiting mechanism 2 is set on the cable gripper 1 and is in an inner sleeve state with the steel wire rope 3, and the tripping and limiting mechanism 2 moves in coordination with the rope-supporting wheel 4. The tripping and limiting mechanism 2 includes a first side plate 21, a second side plate 22, and fastening bolts 24. The first side plate 21 and the second side plate 22 are provided with symmetrical insertion parts 23, and the two insertion parts 23 are inserted and cooperate with the two sides of the horizontal plate on the cable gripper 1. The insertion parts 23 are concave. The first side plate 21 and the second side plate 22 are fastened to the cable gripper 1 by two sets of fastening bolts 24. The upper side of the first side plate 21 and the second side plate 22 is provided with an insertion mechanism and a suspension mechanism. The lower side of the second side plate 22 is provided with an elastic swing mechanism that cooperates with the suspension mechanism. The side of the rope pulley 4 is provided with a rubber roller 29. The roller 29 rolls with the side of the rope pulley 4 and is installed on the lower side of the suspension mechanism.

[0017] As an optional implementation, the insertion mechanism includes a insertion plate 25 and a sleeve 26. The insertion plate 25 and the sleeve 26 are inserted into each other. The insertion plate 25 is fixed on the upper side of the second side plate 22, and the sleeve 26 is fixed on one side of the bottom surface of the fixing plate 26a. The other side of the fixing plate 26a is fixed on the upper side of the first side plate 21. In this way, the first side plate 21 and the second side plate 22 can rely on the insertion mechanism to improve the stability of the clamp on the cable holder 1, thereby providing stable support for the suspension mechanism.

[0018] See attached document Figure 3 The suspension mechanism includes a support plate 27 and a lower extension plate 28. The lower extension plate 28 is symmetrically distributed with the wire rope 3 as the center and the cable gripper 1. The lower extension plate 28 is fixed on one side of the support plate 27. The support plate 27 is located above the position where the cable gripper 1 is installed on the wire rope 3 and is fixed on the fixing plate 26a. The fixing plate 26a is fixed with a bow support plate for reinforcing the support plate 27. In this way, the support plate 27 and the lower extension plate 28 can form a secondary hooking function for the wire rope 3 at the installation position of the cable gripper 1, which is convenient for hooking and coordinating after the cable gripper 1 is detached from the wire rope 3.

[0019] Furthermore, the roller 29 is set on the bottom surface of the lower extension plate 28 and rotatably mounted on the vertical plate, and the vertical plate is vertically mounted on the lower side of the lower extension plate 28. In this way, the roller 29 can rely on the support of the suspension mechanism to form a tension force against separation of the gripper 1 when it passes the rope support wheel 4, thereby improving the anti-separation effect of the gripper 1 when it passes the rope support wheel 4.

[0020] See attached document Figure 4 and attached Figure 5 The elastic swing mechanism includes a swing plate 210, a rotating shaft 211, and an elastic element 212. The elastic element 212 is sleeved on the rotating shaft 211. One side of the swing plate 210 is fixedly connected to the rotating shaft 211, and the other side is rotatably lapped with the overlapping plate 28a. The overlapping plate 28a is vertically set on the lower side of the lower extension plate 28. The elastic element 212 is a torsion spring. In this way, the swing plate 210 and the overlapping plate 28a can form a closed enclosure for the wire rope 3, which is convenient to deal with the situation where the cable gripper 1 detaches from the wire rope 3 during normal movement and drives the suspension mechanism to lap on the wire rope 3, forming secondary protection.

[0021] Furthermore, the rotating shaft 211 is rotatably mounted on the mounting plate 22a, and the mounting plate 22a is fixed to the lower side of the second side plate 22. The bottom surface of the mounting plate 22a is threaded with an upper stop screw 214 for locking the upper outer end of the elastic member 212. The lower outer end of the elastic member 212 is fitted with a lower stop screw 213, and the lower stop screw 213 is threaded on the outer expansion ring on the lower side of the rotating shaft 211. This allows the upper and lower outer ends of the elastic member 212 to be in a limited state, thereby facilitating the response to the reverse rebound force generated by the rotation of the elastic member 212 driven by the swing plate 210.

[0022] See attached document Figure 6 A rubber plate 28b is provided on the side of the lower extension plate 28 corresponding to the wire rope 3, so that when the lower extension plate 28 and the wire rope 3 overlap and come into contact, an anti-slip effect is generated.

[0023] Using the above structure, the following steps are included: I. Installation Steps 1. Install the cable clamp 1 onto the wire rope 3, ensuring it is securely clamped; 2. The first side plate 21 and the second side plate 22 of the tripping and limiting mechanism 2 are inserted and engaged with the horizontal plate of the cable holder 1 through the insertion part 23; 3. Use two sets of fastening bolts 24 to lock the first side plate 21 and the second side plate 22 onto the cable clamp 1 to ensure the stability of the overall structure; 4. Insert the plug plate 25 of the plugging mechanism into the sleeve frame 26 to form a stable connection between the first side plate 21 and the second side plate 22, thereby enhancing the overall rigidity; 5. Fix the suspension support plate 27 of the suspension mechanism to the fixed plate 26a, and ensure that the lower extension plate 28 is symmetrically distributed on both sides of the wire rope 3; 6. Mount the roller 29 on the vertical plate at the bottom of the lower extension plate 28, so that it maintains rolling contact with the side of the rope-supporting wheel 4; 7. Install an elastic swing mechanism so that the swing plate 210 forms a swingable connection with the overlapping plate 28a through the rotating shaft 211 and the elastic element 212, ensuring that it can form a closed enclosure for the wire rope 3.

[0024] II. Installation and Protection Procedures 1. When the cable gripper 1 is operating normally, the lower extension plate 28 of the suspension mechanism is located above the wire rope 3, forming a ready-to-be-attached state; 2. If the clamping force of the cable gripper 1 decreases due to vibration or impact and it comes off the wire rope 3, the lower extension plate 28 of the suspension mechanism will immediately hook onto the wire rope 3 to prevent the monkey car from falling directly. 3. The swing plate 210 of the elastic swing mechanism maintains its enclosure around the wire rope 3 under the action of the elastic element 212, further preventing the wire rope 3 from coming off and ensuring effective secondary protection.

[0025] III. Operating status after passing the support sheave 4 1. When the rope gripper 1 approaches the rope support wheel 4, the roller 29 first contacts the side of the rope support wheel 4, forming rolling friction; 2. The rolling engagement of the roller 29 causes the cable gripper 1 to generate a pulling force toward the rope support roller 4 when passing through the rope support roller 4, preventing the cable gripper 1 from deviating due to lateral impact; 3. The suspension plate 27 and the lower extension plate 28 of the suspension mechanism provide stable support to ensure that the clamping force between the cable gripper 1 and the wire rope 3 is not affected by the rotation of the rope pulley 4; 4. The swing plate 210 of the elastic swing mechanism automatically adjusts its angle when passing the rope pulley 4 to maintain the constraint on the wire rope 3 and prevent accidental derailment.

[0026] This utility model provides stable support when the rope gripper 1 is running normally through the coordinated action of the tripping and limiting mechanism 2, the suspension mechanism and the elastic swing mechanism, achieves secondary attachment protection in case of sudden rope detachment, and enhances the anti-detachment effect when passing the rope support wheel 4, which significantly improves the safety and reliability of the monkey car operation.
