Problems solved by technology

[0003] The first purpose of the present invention is to provide a fixed rope length adjustable crane that can adjust the length of the rope to change the force of the connecting rope, which solves the problem of unadjustable rope length of the existing hook assembly. The problem that it is easy to break when the item is long
[0004] The second object of the present invention is to further provide a fixed rope length that is not easy to shake when lifting objects, has a simple structure, and is not easy to slip when hooking objects. The crane solves the problems that the object will shake when the object is lifted by the existing crane, the appearance is bulky and not suitable for use in a narrow space, the phenomenon of dripping is easy to occur, the lifting distance is small, and the object is easy to slip during use

Embodiment 2

[0046] Embodiment two, the difference with embodiment one is:

[0047] see Figure 7 , also includes hook adjustment motor 4 and power switching mechanism 7. The hook adjustment motor 4 includes a motor housing 41 and a motor shaft 42 . The motor housing 41 is fixedly connected with the grip bar 13 . The drive rod 1 is connected to one end of the motor shaft 42 through a reducer 43 . The other end of the motor shaft 42 passes through the handle bar 13 .

[0048] see Figure 8 , The power switching mechanism 7 includes a switch 71 , a pressing rod 72 , a latch 73 and an insertion spring 74 . The switch 71 and the pressing rod 72 are located on both sides of the latch 73 . The switch 71 is fixed in the handle bar 13 . Switch 71 is a push switch, which is used to control the hook adjustment motor 4 to start and stop. The pressing rod 72 passes through the grip rod 13 . The latch 73 is slidably connected in the handle bar 13 . The motor shaft 42 is provided with a lockin...

Abstract

The invention relates to a lifting appliance. A rope-length-adjustable fixed crane comprises a lifting bracket, a hook assembly, a wire reel and an elevating motor driving the wire reel to rotate. The lifting bracket comprises a vertical rod and a horizontal rod. A mounting plate is arranged at the lower end of the vertical rod and provided with bolt through holes. One end of the horizontal rod are connected to the upper end of the vertical rod, and the elevating motor and the wire reel are fixed to the other end of the horizontal rod. The hook assembly is connected with the wire reel together through a lifting cable. The rope-length-adjustable fixed crane can adjust the rope length to change bearing force of a connecting rope, and the problem that an existing hook assembly is liable to fracture when lifting an object with the large length due to the fact that the rope length cannot be adjusted is solved.

Description

technical field [0001] The invention relates to a spreader, in particular to a fixed crane with adjustable rope length. Background technique [0002] There are basically two types of driving methods for cranes: one is centralized drive, that is, a motor is used to drive the long transmission shaft to drive the driving wheels on both sides; the other is separate drive, that is, the driving wheels on both sides are driven by a motor. Medium and small bridge cranes mostly use the "three-in-one" drive mode that combines brakes, reducers and motors. Ordinary bridge cranes with large lifting capacity are easy to install and adjust. The drive device often uses a universal coupling. . A kind of crane is promptly disclosed in the patent document that the Chinese patent number is 2012203736371, the authorized announcement number is CN202785379, and the name is called "tooling crane". The crane includes a hanger and a hook assembly. The hanger includes a vertical frame and a horizont...
