Problems solved by technology

[0003] The connecting shaft of the crane machinery is used to lift the goods. Since the connecting structure between the connecting shafts is relatively simple, long-term lifting of the goods may affect the inaccurate reset of the connecting shaft, resulting in the restriction of the lifting of the connecting shaft in the later period, and the equipment will not When working in a storage state, due to the lack of a fixing device for the boom, the connecting shaft may shake due to external factors such as vibration and collision, and the safety is low

Embodiment 1

[0023] Example 1, such as figure 1 As shown, the present invention provides a reinforced hoisting machinery connection shaft, including a bottom plate 1 , a workbench 2 is fixedly connected to the top of the bottom plate 1 , and a fixing mechanism 3 is arranged on the top of the workbench 2 .

[0024] Let's talk about the specific setting and function of the fixing mechanism 3 in detail.

[0025] Fixing mechanism 3 comprises fixing bracket 301, and fixing bracket 301 is provided with two, and the bottom of another fixing bracket 301 is fixedly connected with the top of workbench 2, and the opposite side of two fixing brackets 301 is all provided with through groove 302, two The inner surfaces of each through groove 302 are movably connected with a rack 303, the outer surface of the fixed bracket 301 is located below the through groove 302 and is connected with a fixed casing 304 through a rotating shaft, and the inside of the fixed casing 304 is fixedly connected with a clampi...

Embodiment 2

[0027] Example 2, such as figure 2 with 3 As shown, a crossbar 4 is fixedly connected between the two sides of the top of the base 306, the outer surface of the crossbar 4 is rotatably connected with a hanger 5, and the two sides of the top of the hanger 5 are rotatably connected with a rotating sleeve 6, and the rotating sleeve The outer surface of shell 6 is fixedly connected with connecting rod 7, the two sides of the bottom of connecting rod 7 are connected with the both sides of automatic telescopic rod 307 top, and the other end of connecting rod 7 is connected with lifting rod 8 in rotation. An automatic telescopic rod 307 is connected between the base 306, the hanger 5 and the connecting rod 7. When the hanger 5 hoists the connecting rod 7, it is easy to avoid shaking after the connecting rod 7 is lifted by the force of a single direction. As well as the problem of instability, the automatic telescopic rod 307 can serve as an auxiliary support for the connecting rod ...

Embodiment 3

[0028] Example 3, such as figure 2 As shown, both sides of the bottom of the base plate 1 are fixedly connected with a fixed strip 9, the bottom of the fixed strip 9 is fixedly connected with a roller 10, the bottom of the fixed strip 9 is provided with a dark groove 11, and the inner surface of the dark groove 11 is rotatably connected with a limit rod 12. The bottom of the bottom plate 1 is fixedly connected with a fixed frame 13, and the outer surface of the fixed frame 13 is penetrated with a fixed column 14. It is movably connected with the outer surface of the roller 10. A device that can limit the rolling of the roller 10 is added at the bottom of the crane. When the crane is working, the fixed column 14 is pushed to the inside of the fixed frame 13, and the stop bar 12 is put down to contact the outer surface of the roller 10. The limit function is performed to prevent the device from sliding down when it encounters an uneven bottom surface, thereby improving the saf...

Abstract

The invention provides a reinforced hoisting machinery connecting shaft, and relates to the technical field of cranes. The reinforced hoisting machinery connecting shaft comprises a bottom plate, thetop of the bottom plate is fixedly connected with a workbench, the top of the workbench is provided with a fixing mechanism, the fixing mechanism comprises two fixing supports, the bottoms of the twofixing supports are both fixedly connected with the top of the workbench, and through grooves are formed in the opposite sides of the two fixing supports. A fixing mechanism is additionally arranged in the connecting shaft for hoisting machinery, when a machine is not used, racks can be pulled upwards, due to the fact that the racks are movably connected with the inner surfaces of the through grooves, the racks are pulled upwards to move forwards until the two racks get closer and closer to the outer surface of an automatic telescopic rod and a fixed half ring is in contact with the automatictelescopic rod, the racks are released, grooves in the bottoms of the racks are connected with clamping columns at the bottoms in a clamped mode, the automatic telescopic rod is fixed, a connecting shaft device of the crane is prevented from moving, and the safety of the crane is improved.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a reinforced connecting shaft of a hoisting machine. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. The main features of the tire crane are: the driving cab and the lifting control room are combined into one, which is evolved from a crawler crane (crawler crane). The shortcomings of crawler cranes (crawler cranes) that track shoes cause damage to the road surface are eliminated, and they belong to material handling machinery. [0003] The connecting shaft of the crane machinery is used to lift the goods. Since the connecting structure between the connecting shafts is relatively simple, long-term lifting of the goods may affect the inaccurate reset of the connecting shaft, resulting in the restriction of the lifting of the...
