Description

Technical Field

[0001] The present invention belongs to the technical field of silk car traction mechanical devices, and particularly relates to a silk car traction fixture device. Background Art

[0002] When using equipment such as a tractor for silk car traction operations (specifically, a silk car refers to a movable vehicle body loaded with silk reels), tools such as hooks and traction ropes are required for operation. In this way, the silk car can be towed to a designated position for the next process. Currently, it is common to connect the silk car to the tractor through a traction rope or a simple hook, and the tractor drives the silk car to move. However, there are the following deficiencies in the operation: (1) When using a hook or a traction rope, the operator needs to get out of the vehicle to fix the hook or the traction rope on the silk car, which is time-consuming and laborious, and the work efficiency is low; (2) When towing the silk car, when the tractor turns, changes speed or stops, due to inertia, the silk car is prone to large tremors and swings, which can easily cause accidents such as silk cake dropping, rollover, and collision and rear-end collision, with great potential safety hazards; (3) Since the silk car used on-site plus the silk reel weighs about 1 ton, ordinary hook tools are extremely easy to be damaged and broken during use, resulting in extremely high maintenance costs and labor costs, and there are also potential safety hazards.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] In the present invention, the front, rear, upper, lower, left, and right are all referenced with the wire reel traction fixture device. The side connected to the tractor is defined as the front, and the side connected to the wire reel is defined as the rear.

[0033] Example: As Figures 1-4 shown, this example provides a wire reel traction fixture device, which includes a base 1, a support shaft 2, a tractor connecting member 3, a wire reel connecting member 4, a driving mechanism 5, and an elastic member 6. Among them, the support shaft 2 extends in the up and down direction and its lower end is disposed on the base 1; the tractor connecting member 3 is disposed on the base 1 and / or the support shaft 2 and extends in the front and rear direction; the wire reel connecting member 4 is rotatably disposed on the base 1, and the wire reel connecting member 4 includes a first position in the working state and a second position in the non-working state; the driving mechanism 5 is partially disposed on the support shaft 2 and is used to rotate the wire reel connecting member 4 from the second position to the first position, and the elastic member 6 is partially disposed on the support shaft 2 or the base 1 and is used to make the wire reel connecting member 4 tend to remain in the second position.

[0034] In this example, the driving mechanism 5 includes a linkage rod 51 whose middle part is rotatably disposed at the upper end of the support shaft 2 and can rotate in a vertical plane, an operating handle 52 whose upper end is rotatably connected to one end of the linkage rod 51, and a traction rope 53 whose upper end is fixedly connected to the other end of the linkage rod 51. The lower end of the traction rope 53 is connected to the wire reel connecting member 4, and the lower end of the operating handle 52 is detachably connected to the support shaft 2. Specifically, the middle part of the linkage rod 51 can be rotatably connected to the upper end of the support shaft 2 by means of a pin connection. Preferably, the pin in this example is generally U-shaped, and the middle part of the linkage rod 51 passes through the gap of the U-shape and is rotatably connected to the upper end of the pin. Such a setting can facilitate the rotation of the linkage rod 51 in the vertical plane.

[0035] See Figures 1 to 2The operating handle 52 in this example includes a handle rod 521 and a handle fixing hook 522. The upper end of the handle rod 521 is rotatably connected to the linkage rod 51, and the lower end of the handle rod 521 is connected to one end of the handle fixing hook 522. In this example, a fixing column 5a for the handle fixing hook 522 to be hooked is also provided on the support shaft 2. This design method can facilitate the handle fixing hook 522 to remain relatively fixed after being hooked, and can also be easily removed. Furthermore, the groove direction of the handle fixing hook 522 in this example faces forward and downward, that is, facing the direction of the tractor.

[0036] In this example, the traction rope 53 extends in the up-down direction, and the upper end of the traction rope 53 and the lower end of the traction rope 53 are respectively located at the front and rear sides of the support shaft 2. Specifically, the traction rope 53 can be a flexible steel wire rope that is both strong and flexible, with its upper end located at the rear side of the support shaft 2 and its lower end located at the front side of the support shaft 2.

[0037] Further, see Figure 1 and Figure 2 As shown, the traction rope 53 in this example includes a first sub-traction rope 531, a second sub-traction rope 532, and a third sub-traction rope 533. The wire machine connecting member 4 includes a first hook 41 and a second hook 42 arranged on the left and right sides of the support shaft 2. The upper end of the first sub-traction rope 531 is connected to the linkage rod 51, and the lower end of the first sub-traction rope 531 is respectively connected to the upper end of the second sub-traction rope 532 and the upper end of the third sub-traction rope 533. The lower end of the second sub-traction rope 532 is connected to the first hook 41, and the lower end of the third sub-traction rope 533 is connected to the second hook 42. The elastic member 6 extends in the left-right direction and its two ends are respectively connected to the first hook 41 and the second hook 42. Specifically, in this example, the lower end of the first sub-traction rope 531 is respectively connected to the upper end of the second sub-traction rope 532 and the upper end of the third sub-traction rope 533 through a conventional buckle 54.

[0038] The elastic member 6 in this example is a spring. When the thread machine connecting member 4 is in the first position of the working state, the spring is in a compressed and force-storing state. The states of the first hook 41 and the second hook 42 are as follows: Figure 3 When the wire car connector 4 is in the second position of the non-working state, the spring returns to its original state and causes both the first hook 41 and the second hook 42 to rotate outward, and finally the state of the first hook 41 and the second hook 42 is as shown Figure 4 As shown, Figure 3 and Figure 4 The supporting frame 11 in FIG. 1 is shown as an example only in part.

[0039] Specifically, in this example, the first hook 41 and the second hook 42 have the same structure and respectively include a hook shaft 4a rotatably arranged on the base 1 and two hook rods 4b respectively arranged at both ends of the hook shaft 4a, and the included angle between the hook rod 4b and the hook shaft 4a is 70-90°, one of the hook rods 4b is respectively connected to one of the second sub-traction rope 532 and the third sub-traction rope 533 and the elastic member 6, and the other hook rod 4b is used to connect to the wire machine. In the figure, only the hook shaft 4a and the hook rod 4b of the first hook 41 are exemplarily marked.

[0040] Furthermore, in this example, the hook rod 4b is perpendicular to the hook shaft 4a, the hook shaft 4a extends in the front-to-back direction and is horizontally arranged, and when the wire machine connecting member 4 is in the first position of the working state, the hook rod 4b extends in the vertical direction; when the wire machine connecting member 4 is in the second position of the non-working state, the hook rod 4b is arranged in the front-to-back direction and extends in the horizontal direction.

[0041] In this example, when the wire machine connecting member 4 is in the first working position, the lower end of the operating handle 52 is connected to the support shaft 2; when the wire machine connecting member 4 is in the second non-working position, the lower end of the operating handle 52 is separated from the support shaft 2.

[0042] Specifically, in this example, when the wire cart needs to be connected to the traction cart, the operating handle 52 is first used to pull the linkage rod 51 to rotate and make the end of the linkage rod 51 connected to the operating handle 52 move downward. Accordingly, since the middle part of the linkage rod 51 is rotatably arranged on the support shaft 2, the other end of the linkage rod 51 will tilt upward, and then drive the traction rope 53 upward, thereby driving the first hook 41 and the second hook 42 connected thereto to rotate together through the lower part of the traction rope 53, and rotate until the hook rod 4b extends in the vertical direction, at this time, it can hook the rod on the wire cart, and the spring is in the compression storage state. In the force state, the handle fixing hook 522 of the operating handle 52 is hooked on the fixed column 5a so that the hook rod 4b always keeps connected with the rod on the wire car and can drive the movement; when the traction is completed and the wire car needs to be separated from the traction vehicle, the handle fixing hook 522 is directly removed from the fixed column 5a manually, and because the spring is in a compressed and force-storing state during traction, once the external force is removed, the spring will return to its original state, and then drive the first hook 41 and the second hook 42 to rotate together, that is, the hook rod 4b will rotate from extending in the vertical direction to extending in the horizontal direction, and the traction rope 53 can be in a relaxed state. The whole process, whether it is connection when traction is required or separation when traction is not required, can be completed in a very short time, which is fast and convenient, saving time and improving work efficiency.

[0043] In this example, since the fixture device can be fixedly connected to the tractor for a long time, the shape of the tractor connecting member 3 can be designed arbitrarily, as long as it matches the tractor and can be connected thereto. Preferably, the tractor connecting member 3 is provided in the shape of a long plate, and bolt connection holes are formed therein, facilitating detachable connection with the tractor, and having a simple structure and being easy to manufacture.

[0044] Specifically, in this example, referring to Figure 1 and Figure 2 as shown, the base 1 includes a support frame 11, a bottom plate 12, a rib plate 13, and a collision prevention positioning rod 14. The three components of the bottom plate 12, the lower part of the support frame 11, and the rib plate 13 are connected to each other in pairs. The rib plate 13 is vertically fixed below the bottom plate 12 and is located on the front side of the lower part of the support frame 11 and is connected to the lower part of the support frame 11, which can play a role in stable support and maintain the structural stability; the support shaft 2 is respectively connected to the tractor connecting member 3, the upper part of the support frame 11, and the bottom plate 12. The wire car connecting member 4 is rotatably arranged on the lower part of the support frame 11. The collision prevention positioning rod 14 is arranged on the upper part of the support frame 11. The middle part of the elastic member 6 is pressed on the bottom plate 12 or embedded in the bottom plate 12 or welded to the bottom plate 12. Further, there are multiple collision prevention positioning rods 14, which are arranged on the left and right sides of the support frame 11 respectively. The collision prevention positioning rod 14, the bottom plate 12, and the rib plate 13 respectively extend in the front-rear direction; in this example, two collision prevention positioning rods 14 are provided, one on the left side and one on the right side respectively. Its main function is to effectively position the wire car during traction and prevent the wire car from hitting the fixture when towing the wire car, reducing the labor maintenance cost and avoiding the occurrence of safety accidents. At the same time, in this example, the support plates extending in the vertical direction on the left and right sides of the support frame 11 cooperate with the collision prevention positioning rod 14 to support the tail of the nearby wire car, reducing the left and right swing of the wire car, making the wire car smoother and more stable during traction, not easy to roll over, and greatly increasing the safety and reliability of the operation. At the same time, the collision prevention positioning rod 14 also has the function of positioning the wire car, enabling the two hooks of the fixture to more accurately fix the wire car chassis; after positioning the wire car, the operator only needs to pull down the operation handle 52 and hook the handle fixing hook 522 on the fixing column 5a. The linkage rod 51 drives the first hook 41 and the second hook 42 to rotate and flip respectively to lock the wire car chassis through the steel wire rope. The operation is simple and convenient. The operator can complete the process of towing and fixing the wire car without getting off the vehicle, thereby reducing the manual labor cost, shortening the operation time, and greatly improving the manual efficiency. After the wire car arrives, only need to remove the handle fixing hook 522 on the fixing column 5a, and the hook rod 4b is turned outward and downward under the action of the springs at both ends to complete the unhooking process. This fixture has a simple operation and a stable structure; while improving the work efficiency and saving the labor cost, it also increases the safety and reliability of the device.

[0045] In summary, the present invention innovatively provides a silk car traction fixture device with a novel structure. Through the organic combination of the tractor connecting member 3, the silk car connecting member 4, the driving mechanism 5 and the elastic member 6, the whole device can not only be quickly and accurately connected to the silk car and the tractor, but also can be quickly disengaged after traction, solving the problems of manpower, efficiency and safety when the tractor tractions the silk car, and ensuring the safe and efficient progress of production activities.
