Abstract
Description
Technical Field
[0001] This utility model relates to the field of track suspension brackets, and in particular to a track suspension bracket for a monorail. Background Technology
[0002] In industrial settings, there are often situations where small, heavy objects need to be transported. However, it is time-consuming, laborious, and inefficient for workers to move these small, heavy objects. Therefore, people have come up with the idea of using overhead tracks to assist in the hoisting of heavy objects.
[0003] Traditional monorail cranes mainly consist of three parts: anchor rods, connecting components, and rails. During operation, the hoisting device is suspended on the rails via a suspension structure. When it is necessary to lift small heavy objects, the lifting equipment on the hoisting device lifts the heavy objects. Then, relying on manual pushing or mechanical traction, the hoisting device slides along the rails to transport the heavy objects to the designated location, thereby completing the hoisting of small heavy objects within a certain range.
[0004] With industrial development, monorail lifting devices are being used more and more frequently, and the requirements for the track supports for lifting are also becoming higher. However, the installation of traditional monorail lifting track suspension supports mostly relies on anchor rods, bolts and other connecting parts. Once installed, disassembly requires a lot of time to loosen and remove the bolts, which is not only laborious but also inefficient, and can no longer meet the requirements of modern industrial development. Moreover, the height of traditional supports is fixed, and it is difficult to adjust the height once installed. When encountering the need to lift small heavy objects of different heights, or when the working environment has uneven ground, it is impossible to lower the height for easy lifting or raise it to avoid obstacles. Therefore, a new monorail lifting track suspension support is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a track suspension bracket for monorail cranes, which aims to improve the problems of inconvenient disassembly and inability to adjust the height of existing track suspension brackets.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A track suspension bracket for a monorail includes a slide rail, a base fixedly connected to the top of the slide rail, a support column fixedly connected to the top of the base, a retaining ring slidably connected to the outside of the support column, a retaining post fixedly connected to the top of the support column, a frustum seat sleeved on the outside of the retaining post, a retaining cap fixedly connected to the top of the frustum seat, pins slidably connected to both sides of the frustum seat, a baffle fixedly connected to one side of the pin, a second spring fixedly connected to one side of the baffle, and a retaining block fixedly connected to one side of the second spring.
[0008] As a further description of the above technical solution:
[0009] A telescopic rod is fixedly connected to the top of the card block, a threaded post is threadedly connected to the middle of the telescopic rod, a positioning block is fixedly connected to the top of the telescopic rod, positioning pins are fixedly connected to both sides of the positioning block, a placement plate is slidably connected to the top of the positioning block, and a bevel gear is fixedly connected to the top of the placement plate.
[0010] As a further description of the above technical solution:
[0011] The telescopic rod is fitted with a sleeve rod on the outside. The top of the sleeve rod is rotatably connected to a rotating shaft. A bevel gear one is fixedly connected to the outside of the rotating shaft. The bevel gear one meshes with the bevel gear two. A hand crank is fixedly connected to one side of the rotating shaft. Several limiting holes are evenly opened on the side wall of the hand crank.
[0012] As a further description of the above technical solution:
[0013] A fixing plate is fixedly connected to the top of the sleeve rod, and a spring plate is fixedly connected to one side of the sleeve rod. A fixing pin is provided in the middle of the spring plate, and a spring is sleeved on the outside of the fixing pin.
[0014] As a further description of the above technical solution:
[0015] The fixing pin is inserted into one of the limiting holes.
[0016] As a further description of the above technical solution:
[0017] The card block abuts against the card post.
[0018] As a further description of the above technical solution:
[0019] The card block abuts against the card ring.
[0020] As a further description of the above technical solution:
[0021] The end of the rotating shaft away from the first bevel gear is rotatably connected to the outside of the sleeve rod.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, when the truncated cone moves downward and is fitted onto the locking post, the locking block is pressured by the locking post, squeezing the second spring and sliding inside the truncated cone. When the truncated cone moves to the appropriate position, the squeezing force disappears, the second spring rebounds, and the locking block returns to its original position, pressing against the bottom end of the protruding surface of the locking post to achieve locking, thereby lifting the slide rail. When disassembly is required, the truncated cone continues to move downward, and the locking block is squeezed by the top of the retaining ring, pushing the second spring to slide into the truncated cone. When the locking block passes the retaining ring, the second spring returns to its original position. At this time, the bracket is moved upward, and the locking block drives the retaining ring to move upward, thereby allowing the truncated cone to disengage from the support post and achieving disassembly.
[0024] 2. In this utility model, by rotating the hand-cranked disc outside the sleeve rod, the first bevel gear rotates, which in turn drives the second bevel gear meshing with it to rotate, which in turn drives the threaded column to rotate. The placement plate is threadedly connected to the outside of the threaded column. The rotation of the threaded column moves the placement plate threadedly, thereby allowing the telescopic rod to extend and retract, thus realizing the height adjustment of the suspension bracket.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a monorail suspension bracket. A base 2 is fixedly connected to the top of a slide rail 1, and a support column 6 is fixedly connected to the top of the base 2, facilitating the disassembly of the support bracket. A retaining ring 3 is slidably connected to the outside of the support column 6, facilitating the disassembly of the suspension bracket from the slide rail 1. A retaining post 4 is fixedly connected to the top of the support column 6, facilitating the engagement of the bracket with the slide rail 1. A frustum 8 is sleeved on the outside of the retaining post 4, and the engagement of the suspension bracket with the slide rail 1 is achieved after the retaining post 4 and the frustum 8 are sleeved together. A cap 5 is fixedly connected to the top of the frustum 8. The truncated cone base 8 is slidably connected to two sides by pins 7. A baffle 16 is fixedly connected to one side of the pins 7. A second spring 17 is fixedly connected to one side of the baffle 16. A locking block 15 is fixedly connected to one side of the second spring 17. The pins 7, baffle 16, second spring 17 and locking block 15 cooperate with each other to form a self-locking device. When the truncated cone base 8 is fitted onto the locking post 4, the locking block 15 is under pressure and will squeeze the second spring 17. The second spring 17 is in a compressed state. When the pressure on the locking block 15 is removed, the second spring 17 rebounds, so that the locking block 15 can quickly lock into the corresponding protrusion of the locking post 4, completing the fixed connection between the slide rail 1 and the bracket.
[0032] Reference Figure 1 and Figure 2 A telescopic rod 9 is fixedly connected to the top of the locking block 15. A threaded post 18 is threadedly connected to the middle of the telescopic rod 9. The length of the telescopic rod 9 can be adjusted by the cooperation between the telescopic rod 9 and the threaded post 18 when the threaded post 18 rotates. A positioning block 25 is fixedly connected to the top of the telescopic rod 9. Positioning pins 24 are fixedly connected to both sides of the positioning block 25. When the threaded post 18 rotates, the positioning block 25 and the positioning pins 24 cooperate with each other to prevent the telescopic rod 9 and the threaded post 18 from moving in the same direction. A placement plate 19 is slidably connected to the top of the positioning block 25. The sliding connection between the positioning block 25 and the placement plate 19 allows the placement plate 19 to move horizontally, which is convenient for adjusting the position of the bevel gear 23 on the placement plate 19 according to the actual hoisting position requirements. The bevel gear 23 is fixedly connected to the top of the placement plate 19. The bevel gear 23 is installed on the placement plate 19 to facilitate cooperation with other transmission components.
[0033] Reference Figure 1 and Figure 3A sleeve rod 10 is fitted on the outer side of the telescopic rod 9. A rotating shaft 21 is rotatably connected to the top of the sleeve rod 10. A bevel gear 20 is fixedly connected to the outer side of the rotating shaft 21. The bevel gear 20 meshes with a bevel gear 23. A hand crank 13 is fixedly connected to one side of the rotating shaft 21. The sleeve rod 10 fitted on the outer side of the telescopic rod 9, together with the rotating shaft 21, the hand crank 13, and other components, forms a manual adjustment mechanism. When the hand crank 13 is rotated, the rotating shaft 21 rotates accordingly, and the bevel gear 20 fixed on the rotating shaft 21... Gear 1 20 also rotates, and through its meshing with bevel gear 23, it transmits power, thereby realizing the height adjustment of telescopic rod 9. The operation is simple and labor-saving. Several limiting holes 26 are evenly opened on the side wall of hand crank disc 13. After the adjustment is in place, the multiple limiting holes 26 on the side wall of hand crank disc 13 can be used with fixing pin 11 to fix hand crank disc 13, thereby fixing the entire adjustment structure and preventing the position of the support from changing due to gravity during the hoisting of small heavy objects.
[0034] Reference Figure 1 and Figure 3 The top of the sleeve rod 10 is fixedly connected to the fixing plate 12, which is used for the installation of the suspension bracket. A spring plate 22 is fixedly connected to one side of the sleeve rod 10. A fixing pin 11 is provided in the middle of the spring plate 22. A spring 14 is sleeved on the outside of the fixing pin 11. The spring plate 22, the fixing pin 11 and the spring 14 together form a limiting device. When the hand-cranked disc 13 stops rotating, the fixing pin 11 is lowered and inserted into one of the limiting holes 26 opened in the hand-cranked disc 13 to complete the limiting lock.
[0035] Reference Figure 3 The fixing pin 11 is inserted into one of the limiting holes 26. When the height of the telescopic rod 9 is adjusted by the hand crank 13, the fixing pin 11 is inserted into one of the limiting holes 26 to fix the hand crank 13. This ensures that the height of the telescopic rod 9 will not change even if it is subjected to vibration or external impact during the hoisting of small heavy objects.
[0036] Reference Figure 2 The locking block 15 abuts against the locking post 4. When the frustum base 8 is fitted onto the locking post 4, the locking block 15, with the help of the spring 17, engages with the protruding bottom of the locking post 4, thus realizing the installation of the suspension bracket and the slide rail 1.
[0037] Reference Figure 2 The locking block 15 abuts against the locking ring 3, facilitating the disassembly of the frustum base 8 and the locking post 4.
[0038] Reference Figure 1 , Figure 3 The end of the rotating shaft 21 away from the bevel gear 20 is rotatably connected to the outside of the sleeve rod 10, and the other end of the rotating shaft 21 is rotatably connected to the outside of the sleeve rod 10, providing a support point for the rotation of the rotating shaft 21.
[0039] Working principle: When installation and disassembly are required, the clamping post 4 is fixedly connected to the support column 6. The clamping post 4 is slidably connected to the outside of the clamping ring 3. When the truncated cone base 8 moves downward and is fitted onto the clamping post 4, the clamping block 15 inside the truncated cone base 8 is pressured by the clamping post 4, thereby squeezing the second spring 17 to slide inside the truncated cone base 8. When the truncated cone base 8 moves to the bottom of the top protrusion of the clamping post 4, the squeezing force disappears, the second spring 17 rebounds, pushing the clamping block 15 to reset and abut against the bottom of the protrusion of the clamping post 4, thus connecting the suspension bracket with the slide rail 1 and lifting the slide rail 1. When disassembly is required, the truncated cone base 8 needs to be moved downward, and the clamping block 15 moves downward with it, eventually abutting against the bottom of the clamping ring 3. At this time, the truncated cone base 8 is moved upward, and the clamping block 15 will drive the clamping ring 3 to move upward together. When the clamping ring 3 abuts against the bottom of the protrusion of the clamping post 4, the clamping block 15 will continue to move upward along the clamping ring 3, thereby separating the truncated cone base 8 from the clamping post 4, thus achieving disassembly.
[0040] When the height of the bracket needs to be adjusted, the hand crank 13 outside the sleeve rod 10 is turned to drive the bevel gear 20 to rotate, which in turn drives the bevel gear 23 that meshes with it to rotate, which in turn drives the threaded column 18 to rotate. The placement plate 19 is threadedly connected to the outside of the threaded column 18. When the threaded column 18 rotates, the placement plate 19 also moves threadedly, which in turn allows the telescopic rod 9 to extend and retract, thereby realizing the height adjustment of the suspension bracket.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
