Description

Technical Field

[0001] This utility model relates to track laying machine units, specifically to a gravity-operated roller storage basket lifting device. Background Technology

[0002] The WPQZ-500 intelligent long rail tractor and the WPSZ intelligent long rail roller recycling vehicle were originally equipped with four roller storage baskets each, with each basket holding 30 ground rollers, for a total of 120 ground rollers. Track laying verification showed that laying a pair of 500-meter-long rails actually only requires 40 pairs (80 rollers) of ground rollers. In the intelligent track laying process, the mutual transfer between the four full and four empty roller storage baskets in the intelligent long rail tractor and the intelligent long rail roller recycling workshop required nine hoisting operations, taking approximately 40 minutes. If each vehicle were equipped with two roller storage baskets, only five hoisting operations would be needed, potentially saving nearly half the operation time. Furthermore, the time spent positioning the guide frames of the roller storage baskets during the mutual transfer process further increased the transfer time. Based on the above actual situation, the unit's drum storage basket was optimized, resulting in changes to its shape, structure, and dimensions. This made the original lifting equipment no longer suitable for the docking structure and load-bearing capacity of the drum storage basket. Utility Model Content

[0003] To address the problem that existing lifting devices are not suitable for new roller storage baskets, this utility model provides a gravity-operated roller storage basket lifting device that solves the above-mentioned problem.

[0004] A gravity-operated roller storage basket lifting device includes a frame, clamps, a lifting mechanism, an opener / closer, an opening wire rope, and a closing wire rope. The top middle section of the frame is vertically connected to the lifting mechanism, and the bottom ends are horizontally connected to the clamps. The lifting mechanism has two openers / closers. The middle section of the opening wire rope is attached to one of the openers / closers, and both ends pass over the far end of the frame and connect to the clamps. The middle section of the closing wire rope is attached to the other opener / closer, and both ends are connected to the clamps. The opening and closing angles of the two openers / closers are staggered. The lifting mechanism is connected to the opening wire rope via one of the openers / closers, or to the closing wire rope via the other opener / closer.

[0005] In a preferred embodiment of the gravity-operated roller storage basket hanger provided by this utility model, the middle part of the hanger is a hollow box, referred to as the lifting cavity. The top of the lifting cavity is provided with multiple openings, which are movably connected to the lifting mechanism in the vertical direction and allow the opening and closing device to be inserted. The side walls at both ends of the lifting cavity are provided with a pair of openings, which allow the opening wire rope and the closing wire rope to pass through the lifting cavity respectively.

[0006] In a preferred embodiment of the gravity-operated roller storage basket hanger provided by this utility model, a pulley, referred to as the intermediate pulley, is provided on the outer side of the opening at both ends of the middle part of the hanger, and a pulley, referred to as the distal pulley, is provided at each end of the hanger. The middle section of the opening wire rope passes through the lifting cavity below a pair of intermediate pulleys, and the two ends pass around the distal pulleys and are connected to the clamp. The middle section of the closing wire rope passes through the lifting cavity below another pair of intermediate pulleys, and the two ends are connected to the clamp.

[0007] In a preferred embodiment of the gravity-operated roller storage basket hanger provided by this utility model, multiple tracks are provided at the bottom of both ends of the hanger at an angle parallel to the length direction of the hanger, and the tracks are movably connected to the clamp in the horizontal direction.

[0008] In a preferred embodiment of the gravity-operated roller storage basket hanger provided by this utility model, the clamp includes multiple main rods, which are movably connected to multiple tracks. Each main rod has a support rod connected to it at one end in the middle direction, and a gripper is provided at the far end. The gripper is a hook-shaped structure with the opening side facing the middle direction.

[0009] In a preferred embodiment of the gravity-operated roller storage basket lifting device provided by this utility model, both the opening wire rope and the closing wire rope are connected to the support rod. The support rod has a node on its distal side for connecting the end of the opening wire rope, and a node on the top of the support rod for connecting the end of the closing wire rope.

[0010] Compared with the prior art, the gravity-operated roller storage basket hanger provided by this utility model has the following beneficial effects: 1. The lifting device provided by this utility model adopts an opening and closing mechanism that uses a wire rope to achieve the opening and closing of the clamp. It relies on its own weight to achieve opening and closing, which has the advantages of convenient operation and fast opening and closing, making the operation of inverting the roller storage basket more efficient and reducing the inverting time.

[0011] 2. The lifting device provided by this utility model adopts a horizontal track and clamp movement to realize the opening and closing scheme, which can stably connect with the new roller storage basket, ensuring stable connection and accurate positioning between the two during the lifting process, and reducing the time for reversing.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please also refer to Figures 1 to 3 These are, respectively, perspective views of the gravity-operated roller storage basket hanger provided by this utility model from two different perspectives, and a cross-sectional view of the gravity-operated roller storage basket hanger. The wire rope is represented by dashed lines in both figures.

[0016] The gravity-operated roller storage basket lifting device includes a lifting frame 1, a clamp 2, a lifting mechanism 3, an opening and closing device 4, an opening wire rope 5, and a closing wire rope 6.

[0017] The hanger 1 is a rectangular frame structure, including two main beams 11 and multiple crossbeams 12 vertically arranged between the two main beams 11.

[0018] The central crossbeam 12 is a hollow box, designated as the lifting cavity 121. The lifting cavity 121 has an opening at the top center, connecting vertically to the lifting mechanism 3. Openings on both sides of the top allow for the insertion of two opening / closing devices 4. The lifting cavity 121 has a pair of openings on its side walls at both ends, allowing the opening wire rope 5 and closing wire rope 6 to pass through. Pulleys, designated as intermediate pulleys 13, are installed on the outer sides of all four openings. Among the other crossbeams 12, the two uppermost crossbeams 12 are reinforced by a diagonal brace 14, and the lowermost crossbeam 12 has a through-hole opening with a pulley above it, designated as the distal pulley 15.

[0019] The lifting mechanism 3 has mounting holes on both sides for connecting to the crane, and opening and closing devices 4 on the other two sides that are inserted into the lifting cavity 121. A guide rod 31 is provided below the middle position of the lifting mechanism 3, which passes through the lifting cavity 121 downwards and is used for guidance, load bearing and limiting at the lower end.

[0020] At the bottom of each of the two main beams 11, a track 16 is welded at an angle parallel to the main beam 11. The track 16 can be regarded as a square tube structure.

[0021] The clamp 2 includes two main rods 21, which are inserted into two tracks 16 located at the same end to achieve horizontal movement. Each main rod 21 has a support rod 22 at its end near the lifting mechanism 3, which is connected by bolts. Each main rod 21 has a gripper 23 at its distal end. The gripper 23 is an L-shaped plate, forming a hook-like structure with the main rod 21, with the open side facing inwards.

[0022] A node, designated as opening node 221, is located on the side of the support rod 22 near the distal pulley 15 and is connected to the tail end of the opening wire rope 5. The opening wire rope 5 is the wire rope used to open the clamp 2. Its middle section passes through two openings in the side wall of the lifting cavity 121, is located below the two intermediate pulleys 13, and is located next to one of the opening and closing devices 4. Its two ends pass around the distal pulley 15 and are respectively connected to the opening nodes 221 of the two clamps 2.

[0023] Another node, designated as the closed node 222, is located at the top of the support rod 22 and is connected to the tail end of the closed wire rope 6. The closed wire rope 6 is the wire rope used to close the clamp 2. Its middle section passes through two other openings in the side wall of the lifting cavity 121, is located below the other two intermediate pulleys 13, and is located next to the other opening and closing device 4. Its two ends are connected to the closed nodes 222 of the two clamps 2.

[0024] The opening / closing device 4 is a commercially available product. Its basic principle is that its lower hook rotates 90 degrees with each extension and retraction. Therefore, the two opening / closing devices 4 are arranged at staggered angles. Driven by the lifting mechanism 3, the two opening / closing devices 4 extend and retract synchronously. With each extension and retraction, one opening / closing device 4 engages with the open wire rope 5, or the other opening / closing device 4 engages with the closed wire rope 6. For example, when one opening / closing device 4 engages with the open wire rope 5, the hook of the other opening / closing device is perpendicular to it and therefore cannot engage with the closed wire rope 6; conversely, after one extension and retraction, the first opening / closing device 4 rotates 90 degrees and cannot engage with the open wire rope 5, while the other opening / closing device 4 can engage with the closed wire rope 6.

[0025] To ensure the above functions are achieved, the lengths of the open wire rope 5 and the closed wire rope 6 need to be adjusted so that when one wire rope is in a pulled state, the other wire rope is in a passively taut state.

[0026] When unloaded, the lifting mechanism 3 is connected to the crane and pulled up; that is, when the lifting mechanism 3 moves upward relative to the crane frame, one of its opening and closing devices 4 engages and pulls open the wire rope 5. Under the action of the intermediate pulley 13, the opening wire rope 5 converts the upward pulling force into a central pulling force, and then under the action of the distal pulley 15, it converts into an outward pulling force, pulling open the clamp 2. At the same time, the closing wire rope 6 is passively tightened.

[0027] When loading the roller storage basket, the crane places the lifting device above it, then lowers the lifting mechanism 3 and raises it again, causing the two opening and closing devices 5 to extend and retract once, thus switching to another opening and closing device 4 to engage and pull the closing wire rope 6. Under the action of the intermediate pulley 13, the closing wire rope 6 converts the upward pulling force into a central pulling force, bringing the clamp 2 together. The jaws 23 of the clamp 2 hook onto the edge of the roller storage basket, realizing loading. At the same time, the opening wire rope 5 is passively tightened.

[0028] When it is necessary to lower the roller storage basket, the crane lowers the lifting device and the roller storage basket, the moving lifting mechanism 3 moves down and then lifts up again, thereby driving the two opening and closing devices 5 to extend and retract once, thereby switching back to the opening and closing device 4 to hook and pull open the wire rope 5, and pulling open the clamp 2.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
