Description

Technical Field

[0001] This utility model relates to the field of crane technology, and more specifically, to a crane trolley traveling wheel anti-derailment limiting device. Background Technology

[0002] In the prior art, in order to prevent the crane trolley from derailing, especially the suspended crane with electric hoist, an anti-derailment device is installed on the crane trolley. Although the traditional device can ensure that the guide wheel will not fall off the I-shaped guide rail, the protective structure is set on both the top and bottom sides of the I-shaped guide rail, which makes the structure complex and the installation or disassembly more troublesome. Moreover, since the I-shaped guide rail is exposed to the outside for a long time, it is easy to accumulate dust and impurities, making it inconvenient to clean and maintain.

[0003] To solve the above problems, patent document publication number CN222293424U discloses a crane trolley anti-derailment structure, including: a trolley traveling beam, a guide wheel track inside the trolley traveling beam, an anti-derailment groove inside the trolley traveling beam located above the guide wheel track, and an anti-derailment rod slidably connected inside the anti-derailment groove, the anti-derailment rod being T-shaped.

[0004] However, it still has some drawbacks in actual use. For example, the anti-detachment cover in the device is fixed by screws, and the screws are exposed. After long-term use, the screws are prone to rust, which increases the difficulty of disassembly. In addition, the process of disassembling multiple screws in sequence is cumbersome, which affects the disassembly efficiency of the anti-detachment cover and reduces the practicality of the device to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a crane trolley traveling wheel anti-derailment limiting device to solve the problem of inconvenient disassembly of the anti-derailment cover in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a crane trolley traveling wheel anti-derailment limiting device, including a trolley traveling beam, the crane trolley traveling wheel anti-derailment limiting device further includes...

[0007] A connecting column is fixedly installed on the side of the trolley traveling beam;

[0008] A plug-in post is detachably installed inside a connecting post. Rough-surface pads are provided on both sides of the plug-in post in the width direction, and the surface of the rough-surface pads is in contact with the inner wall of the connecting post.

[0009] The mounting plate is fixedly installed on one side of the insertion post along its length. Anti-detachment plates are provided on the left and right sides of the mounting plate, and the interior of the anti-detachment plates is sleeved with the end of the trolley traveling beam.

[0010] It also includes a bonding pad, which is disposed on the surface of the anti-detachment plate, and the inner ring of the bonding pad is bonded to the surface of the side end of the trolley traveling beam.

[0011] It also includes a fixing hole, which is formed on the top surface of the plug.

[0012] The system also includes a first fixing plate, which is fixedly installed on the side of the connecting column opposite to the mounting plate. A screw is rotatably mounted on the surface of the first fixing plate, and a rotating end is fixedly connected to the bottom end of the screw. A sleeve post is threaded onto the surface of the screw, and a top plate is fixedly installed on the top end of the sleeve post. A second fixing plate is provided on the bottom surface of the top plate. The bottom of the second fixing plate passes through the connecting column and is inserted into the interior of the fixing hole. Expansion pads are provided on both sides of the bottom of the second fixing plate, and the side of the expansion pad opposite to the second fixing plate is in contact with the inner wall of the fixing hole.

[0013] A shield is fixedly installed on the top surface of the fixing plate, and the inner wall of the shield is in contact with the surface of the sleeve post.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] In the above scheme, when it is necessary to disassemble the anti-detachment plate sleeved on the end of the trolley traveling beam, by rotating the set rotating end, the screw connected to the top surface of the rotating end rotates synchronously. At this time, the sleeve post sleeved on the outside of the screw moves vertically upward, so as to drive the top plate connected to the top of the sleeve post to move synchronously, so as to drive the second fixing plate to move upward, thereby separating the bottom of the second fixing plate from the fixing hole opened on the top surface of the insertion post. Then the mounting plate can be moved horizontally, so that the insertion post is disassembled from the connecting post, thus completing the disassembly of the anti-detachment plate. This replaces the process of disassembling multiple screws in sequence. Only the rotating end needs to be rotated to separate the second fixing plate from the insertion post to complete the disassembly of the anti-detachment plate, simplifying the disassembly process of the anti-detachment plate and improving the practicality of the device.

[0016] By installing a shield around the screw, the exposed screw can be shielded and protected after the socket is moved vertically upward, preventing foreign objects from adhering to the screw surface and affecting the normal connection between the socket and the screw, thus further improving the practicality of the device.

Rough-surface pads 4 are provided on both sides of the plug-in post 3 in the width direction, and the surface of the rough-surface pads 4 is in contact with the inner wall of the connecting post 2. The rough-surface pads 4 increase the friction between the plug-in post 3 and the connecting post 2 after insertion, further securing the plug-in post 3 and ensuring the stability of the anti-detachment sleeve plate 6 after it is fitted onto the trolley traveling beam 1.

[0026] Mounting plate 5 is fixedly installed on one side of the insertion post 3 along its length. Anti-detachment plates 6 are provided on the left and right sides of mounting plate 5, and the inside of anti-detachment plates 6 is sleeved with the end of the trolley traveling beam 1.

[0027] It also includes a bonding pad 7, which is set on the surface of the anti-detachment plate 6.

By setting the bonding pad 7 around the anti-detachment plate 6, the joint between the anti-detachment plate 6 and the trolley traveling beam 1 can be sealed to prevent moisture and other substances from entering the trolley traveling beam 1 through the gap.

[0028] It also includes a fixing hole 8, which is located on the top surface of the plug post 3.

[0029] The system also includes a fixing plate 9, which is fixedly installed on the side of the connecting column 2 opposite to the mounting plate 5.

[0030] Among them, a shield 16 is fixedly installed on the top surface of the fixing plate 9, and the inner wall of the shield 16 is in contact with the surface of the sleeve post 12.

[0031] The working process of this utility model is as follows: When it is necessary to disassemble the anti-detachment plate 6 sleeved on the end of the trolley traveling beam 1, by rotating the set rotating end 11, the screw 10 connected to the top surface of the rotating end 11 is rotated synchronously. At this time, the sleeve post 12 sleeved on the outside of the screw 10 moves vertically upward, so as to drive the top plate 13 connected to the top of the sleeve post 12 to move synchronously, so as to drive the fixing plate 2 14 to move upward, thereby separating the bottom of the fixing plate 2 14 from the fixing hole 8 opened on the top surface of the insertion post 3. Then the mounting plate 5 can be moved horizontally, so that the insertion post 3 is disengaged from the connecting post 2, thus completing the disassembly of the anti-detachment plate 6.
