Description
Technical field
The utility model is related to a kind of double trolley attachment devices of double trolley jib tower crane.
Background technology
With the rapid development of economy, the construction period is more and more urgent to equipment installation requirement of marching into the arena, for tower lifting
The installation of machine all parts will not only ensure the safety of operation, but also require the high efficiency of working efficiency.Traditional double trolley
All using the connection type for adding axis pin using connecting plate in trolley both sides.The manufacturing cost of enterprise is not only increased, and double
Trolley is connected to be needed to squat or lie prone to carry out pin shaft hole device to hole, pin in crane arm arm support lower plane with operating personnel in lock out operation
Axis is installed, and operating personnel are inconvenient to act, and apart from larger, device to hole degree of difficulty is big for trolley fine motion.Security risk is existed simultaneously, it cannot
Very easy accomplishes rapidly and efficiently.
Utility model content
In view of the defects existing in the prior art, the utility model discloses a kind of double smalls of double trolley jib tower crane
Vehicle New junction device simplifies connection and the separate mode of double trolley, improves the safety coefficient of operating personnel, reasonably reduces enterprise
Industry manufacturing cost.
For this purpose, the utility model takes the following technical solution：A kind of double trolley company of double trolley jib tower crane
Connection device, it is characterised in that ear mount is respectively welded on the crossbeam of preceding trolley and rear trolley, a connection hook is filled by axis pin
In the ear mount for fitting over rear trolley, hanging pin, the connection hook tenesmus and the hanging pin are inserted into the ear mount of the preceding trolley
Engage, safe lever is also set up in the ear mount.
The connection hook rear portion forms the stampeding section of protrusion.
No.1 hole is provided in the ear mount of trolley afterwards, safety stop bar is inserted into the No.1 hole.
No. two holes are provided with positioned at the top of hanging pin in the ear mount of the preceding trolley, another is inserted into described No. two holes
Safe lever.
The beneficial effects of the utility model are：It is hooked by connection and connects hanging pin to realize the connection of double trolley and divide
From, while having safety stop lever in the ear mount of trolley, when being worked using double trolley, being inserted into safety stop lever prevents pedal to be detached from,
When working using single crab, safety stop lever is extracted, steps on pedal, the hanging pin of trolley connection ear mount before being detached from.It is simple in structure, behaviour
Facilitate, improves work efficiency.

Specific implementation mode
As shown in Figs 1-4, the double trolley attachment device of a kind of double trolley jib tower crane of the utility model, preceding
Ear mount is respectively welded on the crossbeam of trolley and rear trolley, a connection hook is assemblied in by axis pin in the ear mount of rear trolley, institute
Hanging pin 5 is inserted into before stating in the ear mount of trolley, 2 tenesmus of connection hook engages with the hanging pin, connection hook rear portion shape
At the stampeding section of protrusion.No.1 hole is provided in the ear mount 1 of trolley afterwards, safety stop bar is inserted into the No.1 hole.Preceding trolley
No. two holes are provided with positioned at the top of hanging pin in ear mount 3, another safe lever 4 is inserted into described No. two holes.
Connection ear mount is respectively welded in front and back small car crossbeam suitable position in the utility model, and connection hook is passed through axis pin
It is assemblied in rear trolley ear mount, preceding trolley connection ear mount is inserted into hanging pin.Company by connecting the connection ear mount for hooking preceding trolley hangs
Sell realize double trolley connection and detach, while preceding trolley connect ear mount on have safety stop lever, work when using double trolley
When, being inserted into safety stop lever prevents pedal to be detached from, and when working using single crab, extracts safety stop lever, steps on pedal, small before being detached from
Vehicle connects the hanging pin of ear mount, and trolley location hole after safety stop lever is inserted into realizes connection hook positioning, to realize double trolley
It quickly connects and detaches, greatly improve the safety of operation.
Specific separation process is as follows：
1. trolley is reached suitable position when double trolley detaches, 4 safety stop lever of part in No. two holes is extracted, foot steps on the company of part 2
It connects the No.1 hole that the hook place of trampling makes pedal upper Positioning holes connect ear mount with part 1 and is aligned 4 safety stop lever of insertion piece, it then will be rear small
Vehicle is fixed on lifting arm roots, and trolley completes operation before outputing.
2. preceding trolley is reached suitable position, extraction No.1 hole by connection hook in the state that raises that breaks off relations when double trolley connects
Safety stop lever, connection hook by from recoil engaging lug seat connecting pin axis rotates down, preceding trolley driven forward, connection hook
Sliding opposite with the hanging pin assembled in connection ear mount, after reaching connection hook groove position, pedal tangles hanging pin, stops trolley
It is mobile, safety stop lever is inserted into No. two holes, completes operation.
Listed above is only specific embodiment of the utility model, and the utility model is not limited to above embodiment,
It is acceptable that there are many deformations.Those skilled in the art directly can export or associate from content disclosed by the utility model
All deformations, be considered as the scope of protection of the utility model.
