Description

Technical Field

[0001] The utility model relates to the technical field of gantry cranes, in particular to a track limiting component of a light gantry crane. Background Art

[0002] Gantry crane is a variation of bridge crane. In ports, it is mainly used for loading and unloading operations in outdoor cargo yards, material yards and bulk cargo. Its metal structure is like a door-shaped frame, with two legs installed under the load-bearing main beam, which can run directly on the ground track. Both ends of the main beam can have outward cantilever beams. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability and strong versatility, and is widely used in port cargo yards.

[0003] Gantry crane is used to lift heavier objects. In actual use, it often needs to be moved through tracks. For this purpose, the tracks need to be installed. A Chinese patent discloses a fixing device for gantry crane tracks (authorization announcement number CN210366679U). This patented technology can loosen the nut, and the long slot holes and bolts can be used to adjust the plane position of each section of the gantry crane track, and then tighten the nut. This utility model is easy to install and can adjust the plane position of the gantry crane track.

[0004] The track of the gantry crane is often adjusted according to needs during actual use. Although this solution can achieve the fixation and subsequent adjustment of the track, it is necessary to loosen the track and then adjust it during actual use. The large number of adjustment steps affects actual use and cannot meet the adjustment needs.

[0005] In order to solve the above problems, we have made improvements and proposed a track limit assembly for a light gantry crane. Utility Model Content

[0029] The fixing device 5 includes a mounting seat 501 arranged on the top of the embedded base 1 and two symmetrically arranged clamps 502 arranged on the top of the mounting seat 501. The clamps 502 are clamped to the two sides of the track 4. The track 4 is clamped and fixed through the cooperation between the mounting seat 501 and the clamps 502 to increase the stability of the track 4.

[0030] A second slide groove 507 is provided inside the mounting seat 501, and two second sliders 503 are slidably connected inside the second slide groove 507. The top of the second slider 503 is fixedly connected to the bottom of the clamp 502. The second slide groove 507 cooperates with the second slider 503 to achieve installation and fixation of the clamp 502 to increase the stability of the clamp 502. The left side of the mounting seat 501 is rotatably connected to a second threaded rod 506 through a bearing. The right side of the second threaded rod 506 penetrates into the second slide groove 507 and is rotatably connected to the second slider 503 through a bidirectional thread. The second slider 503 is synchronously moved closer or farther away through the cooperation between the second threaded rod 506 and the bidirectional thread, thereby synchronously driving the clamp 502 to move and clamping the track 4.

[0031] A protective plate 504 is fixedly installed on the relatively distant side of the two clamps 502, and two protective strips 505 are fixedly installed on the bottom of the protective plate 504. A sealing cavity 508 corresponding to the protective strip 505 is opened on the top of the mounting seat 501, and the protective strip 505 penetrates into the interior of the sealing cavity 508.

[0032] See also Figure 1 , 2And 6, a track limit assembly of a light gantry crane, the adjusting device 3 includes a first slide groove 303 opened inside the embedded base 1 and a first slider 305 slidably connected to the first slide groove 303, the top of the first slider 305 is fixedly connected to the bottom of the mounting seat 501, and the mounting seat 501 is installed and fixed by the cooperation between the first slide groove 303 and the first slider 305, which is convenient for subsequent adjustment of the fixing device 5 and the track 4.

[0033] The right side of the embedded base 1 is provided with an adjusting chamber 301, and the interior of the adjusting chamber 301 is rotatably connected with a first threaded rod 304 through a bearing, and the left side of the first threaded rod 304 passes through the interior of the first slide groove 303 and is rotatably connected with the first slider 305 through a thread. The first threaded rod 304 is accommodated by the setting of the adjusting chamber 301, and the mounting seat 501 is adjusted by the cooperation between the first threaded rod 304, the thread and the first slider 305, thereby driving the track 4 to move and adjust to meet different usage needs. A sealing plate 302 is embedded in the top of the adjusting chamber 301, and a pull ring is fixedly installed on the top of the sealing plate 302. The setting of the sealing plate 302 can protect the adjusting chamber 301 to prevent impurities from entering the interior of the adjusting chamber 301 and affecting the adjustment of the first threaded rod 304. The setting of the pull ring can facilitate the sealing plate 302 to be pulled out from the interior of the adjusting chamber 301 to facilitate the adjustment of the first threaded rod 304.

[0034] The working principle of the utility model is: the whole is pre-embedded to the required position through the pre-embedded base 1 and the pre-embedded pile 2. After the pre-embedding is completed, the second slider 503 and the clamp 502 are pushed to the relatively far side by the rotation of the second threaded rod 506 under the action of the two-way thread, and the track 4 is placed between the two clamps 502. After the placement is completed, the second slider 503 and the clamp 502 are pulled to the relatively close side by the rotation of the second threaded rod 506 under the action of the two-way thread, and the track 4 is fixed by the clamp 502 being clamped to the two sides of the bottom of the track 4. When the position of the track 4 needs to be adjusted, the sealing plate 302 is pulled out from the inside of the adjustment cavity 301 through the pull ring, and the first threaded rod 304 is rotated to push the first slider 305 under the action of the thread to drive the mounting seat 501 and the track 4 to move.
