Technical Field
[0001] This utility model belongs to the technical field of spool transport devices, and in particular relates to a clamp for spool transport. Background Technology
[0002] In the production process of metal fiber cloth, the metal fiber filaments that make up the metal fiber cloth need to be wound and pulled. During the pulling process, in order to ensure the integrity of the metal fiber filaments, a spool needs to be sleeved on them. That is, the spool is sleeved on the outside of multiple metal fiber filaments, and the multiple metal fiber filaments are spliced into a whole, which makes it easier for subsequent production work. When sleeved, the head of the spool also needs to be clamped with a clamp, and then connected to the pulling machine. The pulling force of the pulling machine is used to pull the spool by the clamp. During this process, the metal fiber filaments are kept stationary, so that the spool can be completely sleeved on the metal fiber filaments.
[0003] The existing clamps for pulling spools mainly consist of two opposing clamping plates and a stud for adjusting the gap between the clamping plates. By rotating the stud, the two opposing clamping plates are brought closer or further apart, thereby adjusting the clamping force.
[0004] However, existing spool transport clamps, which use two opposing clamping plates to hold the spool, can only accommodate spools of one diameter because the clamping grooves on the plates are fixed. They cannot stably clamp spools of other diameters, meaning they can only clamp spools of other diameters by using the flat surfaces of the clamping plates. This easily leads to slippage of incompatible spools. Furthermore, when the clamping plates directly clamp the outer wall of the spool and are then hooked onto the traction machine's hook, the horizontal traction force from the traction machine forces the clamping plates to hold the spool during transport. In this case, because the force is applied along the direction of the spool and the metal fiber filaments, the clamping plates are prone to detaching from the spool. Therefore, we provide a spool transport clamp to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a clamp for transporting spools. By using multiple sets of clamping components to cooperate with each other, it can effectively clamp spools of different diameters. By using a hanging component, it can be hung on the side wall of the shaft end of the spool to prevent the spool from falling off during transportation, thus solving the problems of existing clamps for traction of spools.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a clamp for transporting spools of wire, comprising a lower clamping plate and an upper clamping plate, which are rotatably connected by a rotating rod. A clamping assembly is inserted into both the lower and upper clamping plates. Each clamping assembly includes a cylinder threaded to either the lower or upper clamping plate. A sliding rod is slidably inserted into the cylinder, and a spring is also provided inside the cylinder. The spring is connected to the sliding rod via a limiting ring. A stop and a pull ring are detachably fixed to the two ends of the sliding rod. A hook assembly is detachably fixed to the side wall of the lower clamping plate's shaft end. The hook assembly includes an insert plate inserted into the outer wall of the lower clamping plate's shaft end, and the insert plate is slidably connected to the spool via a sliding sleeve welded to it. A second spring is provided inside the sliding sleeve, and the second spring is connected to the spool via a limiting ring. A pull ring and a connecting post are detachably fixed to the two ends of the spool, and the spool is connected to the hook plate via the connecting post.
[0008] The present invention is further configured such that the lower clamping plate and the upper clamping plate are provided with plate holes at equal intervals, and the plate holes on the lower clamping plate are arranged opposite to the plate holes on the upper clamping plate, and the cylinder in the clamping assembly is threadedly connected to the plate holes.
[0009] The present invention is further configured such that a side groove is provided on the side wall of the shaft end of the lower clamping plate, and the lower clamping plate is connected to the insert plate in the hanging assembly through the side groove. There are two side grooves in total, and the two side grooves are symmetrically arranged on both sides of the central axis surface of the lower clamping plate.
[0010] The present invention is further configured such that a mating plate is welded to both the front and rear side walls of one end of the lower clamping plate, and a mating cylinder is welded to one end side wall of the upper clamping plate corresponding to the mating plate, and the mating plate and the mating cylinder are rotatably connected by a rotating rod.
[0011] The present invention is further configured such that a side hole is provided at the other end of the lower clamping plate corresponding to the mating plate, and a side plate is welded to the other end of the upper clamping plate corresponding to the mating cylinder. A pin is inserted through the side plate and the pin passes through the side plate and is inserted into the side hole.
[0012] The present invention is further configured such that the inside of the cylinder is provided with a cylinder groove, and a spring is provided inside the cylinder groove; a limiting ring on the outer wall of the slide rod slides in cooperation with the inner wall of the cylinder groove; and an anti-slip sleeve is fitted on the outer wall of one end of the abutment on the slide rod; the anti-slip sleeve is provided inside the cavity formed by the lower clamping plate and the upper clamping plate.
[0013] The present invention is further configured such that the sliding sleeve is in the shape of a ring, and the two ends of the sliding sleeve are in the form of a through structure. The inner sidewall of the sliding sleeve is slidably engaged with the outer wall of the second limiting ring, and the second limiting ring is detachably fixedly connected to the middle outer wall of the round rod.
[0014] The present invention is further configured such that one end of the round rod with a hanging plate is located inside the cavity formed by the lower clamping plate and the upper clamping plate, and the hanging plate is arranged in a "C" shape, and a soft pad is adhered to the inner wall of the end of the hanging plate.
[0015] This utility model has the following beneficial effects:
[0016] This utility model features clamping components. Clamping components are evenly spaced on both the lower and upper clamping plates, with each component corresponding to the one in the lower clamping plate. In use, pulling the pull ring in the clamping component causes the sliding rod to compress the spring, causing it to contract. Simultaneously, the sliding rod slides within the cylinder, and its shaft ends move away from each other, increasing the cavity between the upper and lower clamping plates. This allows for the storage of larger diameter spools. Once the spool is placed inside, releasing the pull ring causes the spring to extend and press against the limiting ring on the sliding rod, allowing it to slide within the cylinder. The abutment on the sliding rod's shaft end, through an anti-slip sleeve, abuts against the outer wall of the spool, effectively clamping spools of different diameters. Multiple clamping components working together provide a secure grip on the spool.
[0017] This invention features a hook-and-hold assembly. Two sets of hook-and-hold assemblies are detachably and fixedly installed on the side wall of the shaft end of the lower clamping plate. The lower clamping plate can be hooked onto the side wall of the shaft end of the spool via the hook-and-hold assembly. While the traction machine pulls the lower clamping plate, the hook-and-hold assembly's hooking effect propels the spool, preventing it from detaching from the lower clamping plate. In use, the pull ring is held and pulled outwards, causing the round rod to slide outwards within the sliding sleeve. Simultaneously, the round rod also engages with the spring via the limiting ring. The pressure generated compresses the cylinder, and the "C"-shaped hanging plate on the end of the cylinder shaft moves away from the cylinder. When the open end of the hanging plate faces the cylinder and the side wall of the cylinder is between the open ends of the hanging plate, pushing and pulling the cylinder will cause its shaft end to engage with the open end of the hanging plate, thus securing the cylinder shaft end. Then, the lower and upper clamping plates are pulled and moved by the traction force of the traction machine. At this time, the hanging plate abuts against the outer wall of the cylinder shaft end, causing it to move in the direction of the traction force, thus preventing it from slipping off.

Detailed Implementation
[0026] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. Example 1
[0027] Please see Figure 1-4 This utility model is a clamp for transporting yarn drums, including a lower clamping plate 1 and an upper clamping plate 2 rotatably connected thereto. The lower clamping plate 1 and the upper clamping plate 2 can be used to store the yarn drum.
[0028] Specifically, mating plates 103 are welded to the front and rear side walls of the left end of the lower clamping plate 1, and the mating plates 103 are rotatably connected to the mating cylinder 203 through the rotating rod 104 inserted therein, while the mating cylinder 203 is welded to the left side wall of the upper clamping plate 2.
[0029] Furthermore, side plates 201 are welded to the front and rear side walls of the right end of the upper clamping plate 2, and the side plates 201 are engaged with the front and rear side walls of the right end of the lower clamping plate 1. At the same time, a pin 202 is inserted through the side plate 201, and the pin 202 passes through the side plate 201 and is inserted into the insertion hole 102 in the right side wall of the lower clamping plate 1. Example 2
[0030] Please see Figure 5 Based on embodiment 1, a clamping assembly 3 is also provided. By using the clamping assembly 3 installed on the lower clamping plate 1 and the upper clamping plate 2, the outer wall of the spool with different diameters can be clamped.
[0031] Specifically, the cylinder 301 in the clamping assembly 3 is threadedly connected to the plate hole 101 opened on the lower clamping plate 1 or the upper clamping plate 2. A spring 302 is also provided in the cylinder groove 301a inside the cylinder 301, and a slide rod 303 is also slidably inserted in the cylinder 301. The slide rod 303 abuts against the spring 302 through the limiting ring 303a on its outer wall. At the same time, an abutment 303b and a pull ring 303c are respectively provided on the two shaft ends of the slide rod 303. An anti-slip sleeve 304 is also sleeved on the abutment 303b.
[0032] Furthermore, both the lower clamping plate 1 and the upper clamping plate 2 are provided with plate holes 101, and the plate holes 101 on the lower clamping plate 1 and the plate holes 101 on the upper clamping plate 2 are equally spaced. At the same time, the plate holes 101 in the lower clamping plate 1 and the plate holes 101 in the upper clamping plate 2 are arranged opposite to each other. One side of the upper abutment joint 303b of the slide rod 303 is located inside the cavity enclosed by the upper clamping plate 1 and the lower clamping plate 2.
[0033] The operation process of this embodiment is as follows: When in use, by pulling the pull ring 303c in the clamping assembly 3, the slide rod 303 can be forced to compress the spring 302 to retract. At the same time, the slide rod 303 slides in the cylinder 301, and its shaft ends are also moved away from each other, making the cavity between the upper clamping plate 2 and the lower clamping plate 1 larger, so that it can accommodate a larger diameter spool. After the spool is placed in it, the pull ring 303c is released. At this time, the spring 302 extends and abuts against the limiting ring 303a on the slide rod 303, causing the slide rod 303 to slide in the cylinder 301. The abutment 303b on the shaft end of the slide rod 303 abuts against the outer wall of the spool through the anti-slip sleeve 304. Example 3
[0034] Please see Figure 6 Based on Embodiments 1 and 2, a hanging assembly 4 is also provided. By utilizing the spring 403 and the round rod 404 in the hanging assembly, the hanging plate 404c can be hung on the spools of different thicknesses, which can limit the spools and prevent them from detaching.
[0035] Specifically, the mounting component 4 includes an insert plate 401 inserted into a side groove 105 on the side wall of the shaft end of the lower clamping plate 1, and a sliding sleeve 402 is welded on the insert plate 401. The sliding sleeve 402 is in sliding engagement with the round rod 404. A pull ring 404e is fixedly installed at one end of the round rod 404, and a connecting post 404b is fixedly installed at the other end of the round rod 404. The round rod 404 is connected to the mounting plate 404c through the connecting post 404b, and the mounting plate 404c is arranged in a "C" shape.
[0036] Furthermore, the sliding sleeve 402 is a hollow tubular structure with open ends, and a second spring 403 is placed inside the sliding sleeve 402. The second spring 403 abuts against the second limiting ring 404a. At the same time, the second limiting ring 404a is fixedly installed on the outer wall of the round rod 404. A soft pad 404d is also glued to the inner wall of the abutment end of the hanging plate 404c.
[0037] The operation process of this embodiment is as follows: When in use, hold the pull ring 404e and pull it outward, while the round rod 404 slides outward in the sliding sleeve 402. At the same time, the round rod 404 also compresses the spring 403 through the limiting ring 404a. The "C"-shaped hanging plate 404c on the shaft end of the round rod 404 also moves away from the spool. When the open end of the hanging plate 404c faces the spool and the side wall of the spool is located between the open ends of the hanging plate 404c, push and pull the spool so that its shaft end is inserted into the open end of the hanging plate 404c to engage the shaft end of the spool.
