Description

Technical Field

[0001] This utility model relates to the field of rail-mounted cranes, and in particular to a three-dimensional adjustable trolley frame. Background Technology

[0002] Rail-mounted gantry cranes (or simply rail cranes) are container handling equipment that runs on rails. They are mainly used in ports, railway freight yards, and container yards for container loading, unloading, handling, and stacking operations. The equipment consists of a main beam, rigid and flexible gantry legs, a traveling trolley, a hoisting mechanism, and a trolley traveling mechanism.

[0003] The rail-mounted trolley frame is a structural component installed on the main beam of a crane to support and guide the movement of the trolley. It needs to bear the weight of the trolley itself and the entire weight of the hoisted object, and transfer these loads to the main beam.

[0004] Currently, during the manufacturing process of the trolley frame, after the trolley frame is formed, it is still necessary to perform finishing processes such as scraping and boring. However, since the trolley frames are relatively large, conventional machine tools cannot fix such large workpieces. Therefore, it is urgent to study a fixing device to fix such large workpieces as trolley frames to facilitate subsequent finishing processes such as scraping and boring. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a three-dimensional adjustable carriage frame that can effectively align and fix the carriage frame.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a three-dimensional adjustable tire frame for a small vehicle, the innovation of which lies in: including A tire frame base, on which a support unit is provided, the support unit including a translation component and a lifting component; The translation component includes a pair of base platforms disposed on the base of the frame, and the two base platforms move horizontally along the long axis of the frame base, and the base platforms are fixed to the frame base by means of a fixing plate. There are two lifting components, which are respectively set on two base platforms. The lifting components include a pair of lifting platforms distributed side by side on the base platforms. Each lifting platform is driven by an independent lifting cylinder to lift up and down. A clamping plate for fixing the trolley frame is also set on the lifting platform. The clamping plate is fixed to the lifting platform by the cooperation of tension bolts.

[0007] Furthermore, there are two base platforms, each corresponding to one of the two base platforms. Several inverted T-shaped fixing grooves are also provided on the base platforms, distributed along the long axis of the base platforms. The bottom of each base platform is provided with a flange structure for fixing. The two sides of each base platform are fixed to the base platforms by the cooperation of several fixing plates. Each fixing plate presses on the flange structure of the base platform, and the fixing plates are fixed to the base platforms by bolts and nuts.

[0008] Furthermore, the lifting platform is also equipped with support pads.

[0009] The advantages of this utility model are as follows: The jig frame of this utility model supports the trolley frame through the joint cooperation of the jig frame base, translation component and lifting component. It can align the position of the trolley frame in the X, Y and Z axes, providing a good foundation for the subsequent precise machining of the trolley frame for scraping and boring.

[0010] The base platform and the jig base are fixed together by the cooperation of the fixing plate and the flange structure, so that the base platform can be well fixed in any position, providing a stable foundation for the horizontal movement of the base platform relative to the jig base.

[0011] The design of the support pads for the lifting platform is intended to provide auxiliary support for the bottom of the trolley frame, so as to cooperate with the clamping plate to more stably fix the trolley frame. Attached Figure Description

[0013] Figure 2 This is a view of the present invention from direction A. Detailed Implementation

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] like Figure 1 , Figure 2 The illustrated three-dimensional adjustable tire frame includes... The base 2 of the tire frame is rectangular and a support unit is provided on the base 2. The support unit includes a translation component and a lifting component.

[0016] The translation assembly includes a pair of base platforms 3 mounted on the jig base 2. The base platforms 3 are also cuboid in shape, and their major axes are perpendicular to the major axis of the jig base 2. The two base platforms 3 move horizontally along the major axis of the jig base 2, and are fixed to the jig base 2 by means of fixing plates. In this invention, the base platforms 3 are moved horizontally using a gantry crane or a truck crane.

[0017] There are two base frames 2, and two base platforms 3 are respectively set on the two base frames 2. Several inverted T-shaped fixing grooves are also formed on the base frames 2 along their long axis. A flange structure for fixing is provided at the bottom of the base platform 3. The two sides of the base platform 3 are fixed to the base frames 2 by several fixing plates. Each fixing plate presses onto the flange structure of the base platform 3, and the fixing plates are fixed to the fixing grooves of the base frames 2 by bolts and nuts. The base platform 3 is fixed to the base frames 2 through the fixing plates and flange structure, thus ensuring good fixation of the base platform 3 in any position and providing a stable foundation for horizontal movement of the base platform 3 relative to the base frames 2.

[0018] There are two lifting components, which are respectively set on two base platforms 3. The lifting components include a pair of lifting platforms 4 arranged side by side on the base platforms 3. The two lifting platforms 4 are driven to move up and down by independent lifting cylinders set on the base platforms 3. The lifting platforms 4 are also equipped with clamping plates for fixing the trolley frame 1. The clamping plates are fixed to the lifting platforms 4 by the cooperation of tension bolts 42.

[0019] A support pad 41 is also provided on the lifting platform 4. The support pad 41 of the lifting platform 4 is designed to provide auxiliary support for the bottom of the trolley frame 1, so as to cooperate with the clamping plate to more stably fix the trolley frame.

[0020] When using the jig in this utility model to machine the trolley frame 1, firstly, according to the size of the trolley frame 1, the position between the two base platforms 3 is adjusted by means of a gantry crane. Then, the two sides of the trolley frame 1 are supported on each lifting platform 4, and the trolley frame 1 is supported by adding support pads 41 of different thicknesses. Then, the position of the trolley frame 1 is aligned by adjusting the height of different lifting platforms 4. After alignment, the trolley frame 1 is fixed to the lifting platform 4 by a clamping plate to complete the fixing of the trolley frame 1. Then, the trolley frame is processed by scraping, boring and other processes.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
