Description

Technical Field

[0001] The utility model relates to the technical field of painting production lines, in particular to a locking hook mechanism for a traction type painting production line. Background Art

[0002] After retrieval, the patent with the authorization number of CN217867707U discloses a traction type automatic locking hook for a painting production line, which solves the technical problem that the existing traction type automatic locking hook for a painting production line does not have a buffering function; it includes a sleeve and a traction hook. A vertical rod is slidably connected to the sleeve, a buffer spring is sleeved on the surface of the vertical rod, a retaining ring is lapped on the top of the buffer spring, the retaining ring is fixedly connected to the top of the vertical rod, a safety buckle is arranged at the bottom of the vertical rod, a traction hook is fixedly arranged at the bottom end of the vertical rod, and a support block is fixedly arranged at the top end of the vertical rod; through the traction ring in the utility model, it is convenient to connect the traction device. By opening the safety buckle and compressing the torsion spring, the product can be hung on the traction hook. When the traction hook pulls the product, under the action of the pulling force, the retaining ring can compress the buffer spring, and the buffer spring can absorb kinetic energy through deformation, providing buffering for the traction hook and the product.

[0003] The above-mentioned traction type automatic locking hook for a painting production line has the following deficiencies: the operation steps are relatively complex. Before hanging the product on the traction hook, the worker needs to manually toggle the safety buckle to make the safety buckle rotate, and then hang the product on the traction hook. During this period, the worker's hand needs to hold the safety buckle, and the other hand operates to hang the product on the traction hook, which makes it very difficult to hang the product on the traction hook. Moreover, when removing the product, the above steps still need to be followed, with high operation difficulty, which will affect the work efficiency. Therefore, it is necessary to design a locking hook mechanism for a traction type painting production line to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a locking hook mechanism for a traction type painting production line.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The locking plate is provided with a guide plate, and the second guide plate is fixedly connected to the guide plate by the guide plate. The outer wall of the sleeve is fixed to the rod, and since a technical means is adopted that enables the safety baffle to move and contact with the hook of the towing hook during the towing process, the safety baffle can be locked after contacting the hook of the towing hook. After completing the towing work, the product can be put down to move the safety baffle away from the hook of the towing hook, and the product can be locked and removed. This effectively solves the problem that the operating steps proposed in the background technology are relatively complicated. Before hanging the product on the towing hook, the worker needs to manually turn the safety buckle to rotate the safety buckle and then hang the product on the towing hook. During this period, the worker needs to press the safety buckle with his hand and use the other hand to hang the product on the towing hook, which makes it very difficult to hang the product on the towing hook, and when removing the product, it is still necessary to follow the above steps, which has a high operating difficulty and affects the work efficiency. Therefore, the technical effect of low operating difficulty, easy to take and put products, and improved work efficiency is achieved.

[0007] As a further solution of the utility model, the support plate is provided with a fourth guide rod, the support plate is slidably connected to the fourth guide rod, the fourth guide rod is sleeved with a first spring, both ends of the support plate are provided with fifth guide rods, the support plate is slidably connected to the fifth guide rod, and the fourth guide rod and the fifth guide rod are fixedly connected to the top and bottom inner walls of the sleeve.

[0008] As a further solution of the utility model, the tops of both ends of the support plate are fixedly connected with pull rods, the two pull rods pass through the top of the sleeve, the pull rods are slidably connected to the sleeve, and the tops of the two pull rods are fixedly connected with fixed plates.

[0009] As a further solution of the utility model, a tension sensor is fixedly connected to the top of the fixing plate by bolts, and the tension sensor is electrically connected to the display screen by a guide.

[0010] As a further solution of the utility model, a traction ring is fixedly connected to the top end of the tension sensor.

[0011] As a further solution of the utility model, two crescent plates are fixedly connected to the inner wall of the sleeve, and the crescent plates are arranged at the bottom of the support plate.

[0012] As a further solution of the present invention, the outer wall of the sleeve is fixedly connected with a mounting plate, and the mounting plate is fixedly connected with a sleeve plate on the side away from the sleeve, and the sleeve plate is penetrated by a sixth guide rod, and the sixth guide rod is slidably connected to the sleeve plate, and the two sixth guide rods are sleeved with a second spring, and the same side of the two sixth guide rods are fixedly connected to the same trapezoidal plate, and the two sixth guide rods are fixedly connected to the same handle on the side away from the trapezoidal plate, and the trapezoidal plate is a beveled edge on the side away from the sleeve. Since the technical means of using the trapezoidal plate to limit the position of the slide rail are adopted, the slide rail will squeeze the trapezoidal plate when the slide rail moves, and the trapezoidal plate will move when the slide rail moves past the trapezoidal plate. After the slide rail moves past the trapezoidal plate, the second spring will stretch out to make the trapezoidal plate block the slide rail and limit the position of the slide rail, which can ensure that the locking effect is always effective, and when the locking is canceled, the baffle plate no longer blocks the slide rail by simply pulling the handle, and the safety baffle plate no longer contacts the hook of the traction hook, and the locking can be canceled.

[0013] The beneficial effects of the utility model are:

[0014] The utility model adopts a technical means that can make the safety baffle move and contact with the hook of the towing hook during the towing process, so the safety baffle can play a locking effect after contacting the hook of the towing hook. After completing the towing work, the product can be put down to move the safety baffle away from the hook of the towing hook, and the product can be locked and removed. The problem of complicated operation steps proposed in the background technology is effectively solved. Before hanging the product on the towing hook, the worker needs to manually turn the safety buckle to rotate the safety buckle and then hang the product on the towing hook. During this period, the worker needs to press the safety buckle with his hand and use the other hand to hang the product on the towing hook, which makes it very difficult to hang the product on the towing hook. When removing the product, it is still necessary to operate according to the above steps, which is difficult to operate and will affect the work efficiency. Therefore, the technical effect of low operation difficulty, easy to take and put products, and able to improve work efficiency is achieved.

[0015] The utility model adopts the technical means of limiting the position of the slide rail by adopting the trapezoidal plate. Therefore, when the slide rail moves, the slide rail will squeeze the trapezoidal plate. After the slide rail moves and passes the trapezoidal plate, the second spring will stretch out to make the trapezoidal plate block the slide rail, limiting the position of the slide rail. This can ensure that the locking effect is always effective. When canceling the locking, it is only necessary to pull the handle so that the baffle no longer blocks the slide rail, and the safety baffle no longer contacts the hook of the traction hook, thereby canceling the locking.

Detailed Description of the Preferred Embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Next, the present utility model will be described in detail with reference to the drawings and in combination with the embodiments.

[0026] Reference Figures 1 - 7 , a locking hook mechanism for a traction type painting production line, including a sleeve 1. The bottom of the sleeve 1 is fixedly connected with a traction hook 2 through bolts. A support plate 3 is slidably connected to the inner wall of the sleeve 1. One end of the bottom of the support plate 3 is fixedly connected with a first sliding block 4. The first sliding block 4 is sleeved with a slide rail 5. The first sliding block 4 is slidably connected to the slide rail 5. The bottom of the slide rail 5 is fixedly connected with a second sliding block 6. The second sliding block 6 is sleeved with a guide plate 7. The second sliding block 6 is slidably connected to the guide plate 7. The guide plate 7 passes through the bottom of the sleeve 1 and the top of the traction hook 2. The guide plate 7 is slidably connected to the sleeve 1 and the traction hook 2. The bottom of the guide plate 7 is fixedly connected with a safety baffle 8. Both ends of the guide plate 7 are provided with a first guide rod 9. The top of the first guide rod 9 is fixedly connected with the traction hook 2. One side of the bottom end of the slide rail 5 is fixedly connected with a second guide rod 10. The second guide rod 10 passes through the outer wall of the sleeve 1. One side of the top end of the slide rail 5 is fixedly connected with a T-shaped plate 11. Both ends of the T-shaped plate 11 are provided with a third guide rod 12. The third guide rod 12 is fixedly connected to the outer wall of the sleeve 1. Due to the technical means that the safety baffle can move and contact the hook of the traction hook during the process of towing the product, after the safety baffle contacts the hook of the traction hook, it can play a locking effect. After the towing work is completed, the product is put down, and the safety baffle can move away from the hook of the traction hook, and the lock can be released to remove the product. It effectively solves the problem that the operation steps in the background technology are relatively complex. Before hanging the product on the traction hook, the worker needs to manually dial the safety buckle to make the safety buckle rotate, and then hang the product on the traction hook. During this period, the worker's hand needs to hold the safety buckle, and the other hand operates to hang the product on the traction hook, resulting in great difficulty in hanging the product on the traction hook. And when removing the product, the above steps still need to be followed for operation, with high operation difficulty and affecting work efficiency. Furthermore, it realizes the technical effects of low operation difficulty, convenient product taking and placing, and can improve work efficiency.

[0027] In this embodiment, a fourth guide rod 13 passes through the support plate 3. The support plate 3 is slidably connected to the fourth guide rod 13. The fourth guide rod 13 is sleeved with a first spring 14. Both ends of the support plate 3 are provided with a fifth guide rod 15. The support plate 3 is slidably connected to the fifth guide rod 15. The fourth guide rod 13 and the fifth guide rod 15 are fixedly connected to the inner walls of the top and bottom of the sleeve 1.

[0028] In this embodiment, both ends of the top of the support plate 3 are fixedly connected with a pull rod 16. Both pull rods 16 pass through the top of the sleeve 1. The pull rods 16 are slidably connected to the sleeve 1. The tops of both pull rods 16 are fixedly connected with a fixed plate 17.

[0029] In this embodiment, the top of the fixed plate 17 is fixedly connected with a tensile sensor 18 through bolts. The tensile sensor 18 is electrically connected to a display screen 20 through a guide wire.

[0030] In this embodiment, a traction ring 19 is fixedly connected to the top end of the tension sensor 18.

[0031] In this embodiment, two crescent plates 21 are fixedly connected to the inner wall of the sleeve 1, and the crescent plates 21 are arranged at the bottom of the support plate 3.

[0032] In this embodiment, a mounting plate 22 is fixedly connected to the outer wall of the sleeve 1. A sleeve plate 23 is fixedly connected to the side of the mounting plate 22 away from the sleeve 1. A sixth guide rod 24 passes through the sleeve plate 23, and the sixth guide rod 24 is slidably connected to the sleeve plate 23. Two second springs 25 are sleeved on the two sixth guide rods 24. The same trapezoidal plate 26 is fixedly connected to the same side of the two sixth guide rods 24. The same handle 27 is fixedly connected to the side of the two sixth guide rods 24 away from the trapezoidal plate 26. The side of the trapezoidal plate 26 away from the sleeve 1 is an inclined side. Due to the technical means of using the trapezoidal plate to limit the position of the slide rail, when the slide rail moves, the slide rail will squeeze the trapezoidal plate and the trapezoidal plate will move. After the slide rail moves past the trapezoidal plate, the second spring will stretch to make the trapezoidal plate block the slide rail and limit the position of the slide rail, which can ensure that the locking effect is always effective. When unlocking, just pull the handle to make the baffle no longer block the slide rail, so that the safety baffle no longer contacts the hook of the traction hook, and the locking can be cancelled.

[0033] Working principle: When using this device, connect the towing ring 19 to the towing equipment, hang the product on the towing hook 2, and then start the towing equipment to move the towing ring 19 away from the product. The tension sensor 18 can monitor the tension received by the towing hook 2 and transmit the monitoring data to the display screen 20. Through the display screen 20, the staff can detect the quality of the product, and it is convenient to weigh the product during the towing process. During towing, the towing ring 19 pulls the tension sensor 18, the tension sensor 18 pulls the fixed disk 17, the fixed disk 17 pulls the pull rod 16, and the pull rod 16 pulls the support plate 3, causing the support plate 3 to move along the fifth guide rod 15. The support plate 3 will not shift during movement. The movement of the support plate 3 also squeezes the first spring 14 to contract the first spring 14. Through deformation, the first spring 14 can absorb kinetic energy and provide buffering for the towing hook 2 and the product. When the towing speed suddenly increases, it can maintain the stability of the towing tension and avoid the increase of the towing tension. When the support plate 3 moves away from the towing hook 2, it will also drive the first sliding block 4 to move. The first sliding block 4 will move along the slide rail 5, and the first sliding block 4 will squeeze the slide rail 5 to move the slide rail 5 into the interior of the sleeve 1. The movement of the slide rail 5 will drive the second guide rod 10 to move, and the slide rail 5 will also drive the T-shaped plate 11 to move along the third guide rod 12. The slide rail 5 will not shift during movement. When the slide rail 5 moves into the interior of the sleeve 1, it will drive the second sliding block 6 to move along the top guide rail of the guide plate 7. The second sliding block 6 will squeeze the guide plate 7 to move the guide plate 7 away from the towing ring 19. The movement of the guide plate 7 will move along the first guide rod 9. The guide plate 7 will not shift during movement. The movement of the guide plate 7 will also drive the safety baffle 8 to move. When the safety baffle 8 moves until it contacts the hook of the towing hook 2, it can be locked to prevent the product from falling. If the slide rail 5 continues to move when it contacts the hypotenuse of the trapezoidal plate 26 when moving into the interior of the sleeve 1, the slide rail 5 will squeeze the trapezoidal plate 26 to move the trapezoidal plate 26 a certain distance in the direction of the sleeve plate 23. The movement of the trapezoidal plate 26 will drive the sixth guide rod 24 to move along the sleeve plate 23 and simultaneously contract the second spring 25. When the slide rail 5 moves past the trapezoidal plate 26, the second spring 25 will expand to return the trapezoidal plate 26 to its initial position, making the trapezoidal plate 26 block on the side of the slide rail 5 away from the sleeve 1. At this time, the first sliding block 4 is on the long guide rail of the slide rail 5, and the safety baffle 8 also contacts the hook of the towing hook 2. By making the trapezoidal plate 26 block on one side of the slide rail 5, the position stability of the slide rail 5 can be ensured, and thus the position stability of the safety baffle 8 can also be ensured, avoiding the failure of locking caused by the movement of the safety baffle 8 during towing and ensuring the safety during towing work. After completing the towing work, place the product. The staff can manually pull the handle 27 to move the handle 27, so that the trapezoidal plate 26 no longer blocks on one side of the slide rail 5. After putting down the product and continuing to lower the towing ring 19, the first spring 14 can also expand, causing the support plate 3 to move towards the towing hook 2.The pallet 3 will drive the first sliding block 4 to move towards the direction of the towing hook 2. The first sliding block 4 will squeeze the slide rail 5 again, causing the slide rail 5 to gradually move out of the inside of the sleeve 1. At this time, the second sliding block 6 will also squeeze the guide plate 7 again, causing the guide plate 7 to rise, so that the safety baffle 8 will no longer contact the hook of the towing hook 2, and the locking can be released. Then the product can be taken out, and the work can be continued according to the same steps.
