Description

Technical Field

[0001] This utility model relates to the field of emergency braking technology for cranes, specifically an emergency braking anti-slip device for cranes. Background Technology

[0002] Cranes are important material handling equipment in industrial production. In actual operation, cranes may encounter various complex working conditions, such as heavy load, high speed operation, and emergency stop, which may cause the crane to slip. Therefore, the application of emergency braking anti-slip device in cranes is particularly important.

[0003] A search of Chinese patent CN222005079U reveals an anti-slippage emergency braking device, comprising upright plates and a housing. The housing is fixedly connected to the outer walls of both upright plates. An emergency braking device is installed inside the housing, comprising a motor and a first bevel gear. The motor is fixedly connected to the outer wall of the housing. The motor drives the first bevel gear to rotate, which in turn drives a second bevel gear to rotate. The second bevel gear drives a threaded rod to rotate, which in turn moves a threaded block. The threaded block slides inside the housing, causing the vertical plate to move. The vertical plate then moves a cylinder, which in turn moves a column. The column slides inside the housing, causing a horizontal plate to descend. By using a single motor to move the corresponding mechanical structure, the vehicle is locked in place. This reduces the inspection and maintenance costs of the anti-slippage emergency braking device, thus lowering its overall cost.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The rails on the crane are exposed to the outside world for a long time, and dust and debris are easy to accumulate on the surface of the rails, which affects the emergency braking operation and makes it inconvenient to repair the wear of the brake blocks for emergency braking. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an emergency braking anti-slip device for cranes.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides an emergency braking anti-slip device for a crane, including a mounting base. Two electric telescopic rods are symmetrically arranged on the mounting base. A brake frame is fixedly installed on the telescopic end of each electric telescopic rod. A brake block is fixedly installed on the brake frame. A scraping mechanism is provided on each brake frame. The scraping mechanism includes two support components symmetrically arranged on the brake frame. A mounting shell is provided on each support component. A bracket is movably installed on the inner side of the mounting shell. A scraper is fixedly installed on the bracket. A mounting bolt adapted to the bracket is threaded on the mounting shell. A snap-fit ​​component is provided on the mounting shell. A positioning component is provided on the fixed shell.

[0008] The mounting base is provided with a measuring mechanism, which includes a fixed rod fixedly mounted on the mounting base and movably connected to the two brake frames. The fixed rod has an inner side with two movable components. Each movable component is provided with a telescopic pointer. The fixed rod is marked with a scale that matches the telescopic pointer.

[0009] Furthermore, the support assembly includes a circular shell fixedly mounted on the brake frame, and a circular block fixed to the mounting shell is rotatably mounted on the inner side of the circular shell.

[0010] Furthermore, the snap-fit ​​assembly includes two side shells fixedly mounted on the mounting housing, each side shell having a first spring connected to its inner wall, and the end of the first spring having a snap-fit ​​block adapted to the side shell.

[0011] Furthermore, the insert has two symmetrically arranged slots that are adapted to the card block.

[0012] Furthermore, the positioning component includes a threaded block fixedly mounted on the mounting housing, a positioning bolt threaded onto the threaded block, and a fixing block adapted to the positioning bolt fixedly mounted on the brake frame.

[0013] Furthermore, the movable component includes a second spring connected to the inner wall of the inner groove, the end of the second spring being connected to a movable block adapted to the inner groove, a long sleeve being fixedly installed on the movable block, and a third spring connected to the telescopic pointer being connected to the inner wall of the long sleeve.

[0014] Furthermore, a pull bar is fixedly installed on each of the telescopic pointers.

[0015] The above-described solution of this utility model has at least the following beneficial effects:

[0016] 1. In this utility model, the insert bracket is inserted into the inner side of the mounting shell, and the insert bracket is supported by the interlocking of the locking block and the locking groove. The mounting bolt is screwed into the inner side of the insert bracket through the mounting shell, thereby fixing the insert bracket. The scraper is rotated, causing the mounting shell to rotate through the insert bracket, and the mounting shell causes the round block to rotate inside the round shell, so that the scraper is aligned with the brake block. The positioning bolt is screwed into the inner side of the fixing block through the threaded block. During emergency braking, the scraper can scrape the rails on the crane, thereby facilitating the cleaning of dust and debris and improving the emergency braking effect.

[0017] 2. In this utility model, the movable long sleeve drives the movable block to move along the inner side of the inner groove, which in turn drives the telescopic pointer to move. At the same time, the pull bar drives the telescopic pointer to move, so that the telescopic pointer moves to fit with the brake block. Thus, the wear of the brake block can be measured by the position of the long sleeve on the scale, which facilitates maintenance work. Attached Figure Description

[0025] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0026] like Figures 1 to 5 As shown, an embodiment of this utility model provides an emergency braking anti-slip device for a crane, including a mounting base 1. Two electric telescopic rods 2 are symmetrically fixed on the mounting base 1. A brake frame 3 is fixedly installed on the telescopic end of each electric telescopic rod 2, and a brake block 4 is fixedly installed on the brake frame 3.

[0027] In this embodiment of the utility model, when the trolley and carriage on the crane need to perform emergency braking, the telescopic end of the electric telescopic rod 2 is extended, so that the telescopic end of the electric telescopic rod 2 drives the brake block 4 to move through the brake frame 3, so that the brake block 4 rubs against the rail on the crane, thereby performing emergency braking.

[0028] Figures 1 to 5 As shown, each brake frame 3 is equipped with a scraping mechanism, which includes two support components symmetrically arranged on the brake frame 3. Each support component is equipped with a mounting shell 7, and a bracket 8 is movably mounted on the inner side of the mounting shell 7. A scraper 9 is fixedly mounted on the bracket 8. A mounting bolt 10 adapted to the bracket 8 is threaded onto the mounting shell 7. A snap-fit ​​component is provided on the mounting shell 7, and a positioning component is provided on the fixed shell. The support component includes a circular shell 5 fixedly mounted on the brake frame 3, and a mounting bolt 10 that is compatible with the bracket 8 is rotatably mounted on the inner side of the circular shell 5. The round block 6 is fixed to the mounting shell 7. The snap-fit ​​assembly includes two side shells 11 fixedly installed on the mounting shell 7. The inner wall of each side shell 11 is connected to a first spring 12. The end of the first spring 12 is connected to a snap-fit ​​block 13 that is adapted to the side shell 11. The insert 8 has two symmetrically opened slots 14 that are adapted to the snap-fit ​​block 13. The positioning assembly includes a threaded block 15 fixedly installed on the mounting shell 7. A positioning bolt 16 is threadedly installed on the threaded block 15. A fixing block 17 adapted to the positioning bolt 16 is fixedly installed on the brake frame 3.

[0029] In this embodiment of the utility model, the operator inserts the bracket 8 into the inner side of the mounting shell 7. The first spring 12 supports the locking block 13 using its own elasticity. The locking block 13 and the locking groove 14 engage to support the bracket 8. The mounting bolt 10 is screwed into the inner side of the bracket 8 through the mounting shell 7 to fix the bracket 8. The scraper 9 is rotated, causing the mounting shell 7 to rotate through the bracket 8. The mounting shell 7 then causes the round block 6 to rotate inside the round shell 5, aligning the scraper 9 with the brake block 4. The positioning bolt 16 is screwed into the inner side of the fixing block 17 through the threaded block 15. During emergency braking, the scraper 9 can scrape the rails on the crane, facilitating the cleaning of dust and debris and improving the emergency braking effect.

[0030] Figures 1 to 5 As shown, a measuring mechanism is provided on the mounting base 1. The measuring mechanism includes a fixed rod 18 fixedly installed on the mounting base 1, and the fixed rod 18 is movably connected to two brake brackets 3. The fixed rod 18 has an inner side, on which two movable components are provided. Each movable component is provided with a telescopic pointer 24. The fixed rod 18 is marked with a scale 26 that matches the telescopic pointer 24. The movable component includes a second spring 20 connected to the inner wall of the inner groove 19. The end of the second spring 20 is connected to a moving block 21 that matches the inner groove 19. A long sleeve 22 is fixedly installed on the moving block 21. The inner wall of the long sleeve 22 is connected to a third spring 23 that matches the telescopic pointer 24. Each telescopic pointer 24 is fixedly installed with a pull bar 25.

[0031] In this embodiment of the utility model, the operator moves the long sleeve 22, causing the long sleeve 22 to drive the moving block 21 to move along the inner side of the inner groove 19, causing the long sleeve 22 to drive the telescopic pointer 24 to move. At the same time, the pull bar 25 drives the telescopic pointer 24 to move, so that the telescopic pointer 24 moves to fit with the brake block 4 under the support of the elastic force of the second spring 20. Thus, the wear of the brake block 4 can be measured by the position of the long sleeve 22 on the scale 26, which facilitates maintenance work.

[0032] After the maintenance is completed, loosen the pull bar 25 so that the third spring 23 can use its own elasticity to drive the telescopic pointer 24 to move into the inside of the long sleeve 22, and the second spring 20 can use its own elasticity to drive the telescopic pointer 24 to reset through the moving block 21 and the long sleeve 22.

[0033] Working principle: When the trolley and crane need to perform emergency braking, the telescopic end of the electric telescopic boom 2 is extended, and the telescopic end of the electric telescopic boom 2 drives the brake block 4 to move through the brake frame 3, so that the brake block 4 rubs against the rail on the crane, thereby performing emergency braking.

[0034] By inserting the bracket 8 into the inner side of the mounting housing 7, the bracket 8 is supported by the interlocking of the locking block 13 and the locking groove 14. The mounting bolt 10 is screwed into the inner side of the bracket 8 through the mounting housing 7 to fix the bracket 8. The scraper 9 is rotated so that the mounting housing 7 is rotated through the bracket 8, and the mounting housing 7 drives the round block 6 to rotate inside the round housing 5, so that the scraper 9 is aligned with the brake block 4. The positioning bolt 16 is screwed into the inner side of the fixing block 17 through the threaded block 15. During emergency braking, the scraper 9 can scrape the rails on the crane to clean up dust and debris.

[0035] The staff moves the long sleeve 22, causing the long sleeve 22 to move the moving block 21 along the inner side of the inner groove 19, which in turn causes the long sleeve 22 to move the telescopic pointer 24. At the same time, the pull bar 25 moves the telescopic pointer 24 so that it is in contact with the brake block 4. The wear of the brake block 4 is measured by the position of the long sleeve 22 on the scale 26, and maintenance work is carried out.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
