Description
Technical field
The utility model relates to hoisting machinery fields, and in particular to a kind of crow bar of outdoor crane traveling mechanism of the larger traveller
Manual rail clamping device.
Background technique
Outdoor crane draught exclusion device requires to must be provided with rail clamping device, and wherein Manual rail clamping device is substantially A380 type, this
Kind rail clamping device structure is complicated, and outer dimension is big, at high cost, and mismatch is used on some legerity type cranes.It is light and handy to match
The radix saposhnikoviae of type outdoor use crane clamps, and Manual rail clamping device suitable configurations are succinct, reduces size.
Utility model content
In view of the above technical problems, the purpose of the utility model is to provide a kind of crow bar Manual rail clamping devices.
The technical solution of the utility model specifically:
A kind of crow bar Manual rail clamping device, including backboard, it is fixed there are two shaft end plate on backboard, it is arranged between two shaft end plates
There is shaft, caliper body is arranged in shaft, clamp caliper hook is fixed in caliper body, otic placode is fixed on backboard, otic placode is logical
Pin shaft connecting clamp hook is crossed, double-end lead-screw is equipped in caliper body, screw thread is provided on double-end lead-screw, is combined with one at screw thread
To L-type screw chuck, two L-type screw chucks are located at the two sides of caliper body.
One end of the double-end lead-screw is provided with torsion lever.
Travel switch is fixed on one of shaft end plate.
The double-end lead-screw is provided with two sections of screw threads in caliper body two sides, two sections of screw threads it is oppositely oriented, double-end lead-screw with
The contact surface of caliper body is smooth.
Compared with the existing technology, the technical effect of the utility model is, by dialing up caliper body, so that L-type lead screw
Collet de-orbits, and double-end lead-screw touches travel switch simultaneously, and crane operates normally, by stirring caliper body downwards, so that L
Type screw chuck falls and turns the clamping that torsion lead screw realizes L-type screw chuck in orbit.
It is consistent with rail profiles that L-type screw chuck clamps face, can be pasted completely when clamp body running as track floats
It closes, reaches reliable grip, and there is anti-tipping function, L-type screw chuck forms crow bar stress form, reliable clamping, operation
Simply.
The utility model shape is light and handy, and for gross weight less than 50kg, principle is simple, and easily manufactured, outer dimension is small, protection effect
It is good.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the schematic perspective view of the utility model.
Specific embodiment
As shown in figs. 1-2, a kind of crow bar Manual rail clamping device, including backboard 9, fixed on backboard 9 there are two shaft end plates
8, travel switch 6 is fixed on one of shaft end plate 8, and shaft 10 is provided between two shaft end plates 8, folder is arranged in shaft 10
Caliper 4 is fixed with caliper body hook 7 in caliper body 4, is fixed with otic placode on backboard 9, otic placode by pin shaft connecting clamp hook 5,
Double-end lead-screw 2 is equipped in caliper body 4, one end of double-end lead-screw 2 is provided with torsion lever 1, and double-end lead-screw 2 is at 4 liang of caliper body
Side is provided with two sections of screw threads, two sections of screw threads it is oppositely oriented, a pair of of L-type screw chuck 3, two L-type lead screws are combined at screw thread
Collet 3 is located at the two sides of caliper body 4, and double-end lead-screw 2 and the contact surface of caliper body 4 are smooth.
The working process of the utility model is as follows: lift caliper body 4 manually when starting outdoor crane, caliper body 4 is arranged
In shaft 10, double-end lead-screw 2 is equipped in caliper body 4, caliper body hook 7 is fixed in caliper body 4, therefore, is pressed from both sides when lifting
When caliper 4, caliper body 4 can rotate around shaft 10, and double-end lead-screw 2, caliper body hook 7 can be rotated together with caliper body 4,
At this point, L-type screw chuck 3 can de-orbit, the clamping action to track is released, allows clamp to link up with 5 and folder after lifting caliper body 4
Caliper hook 7 tangles, and double-end lead-screw 2 can touch travel switch 6, and crane can operate normally.
It needs rail clamping device to clamp Crane Rail when outdoor crane stops working, driving is made to be not easy to slide and overturn,
Clamp hook 5 is unclamped when parking, caliper body 4 is fallen on track, and a pair of of L-type screw chuck 3 falls in track two sides, travel switch 6
It disconnects, crane cannot work.Double-end lead-screw 2 is driven to rotate by rotating torsion lever 1 manually, due to 3 weight of L-type screw chuck
Measure it is larger, double-end lead-screw 2 rotate during, L-type screw chuck 3 will not be rotated with double-end lead-screw 2, be remained straight down
State, the rotation of double-end lead-screw 2 keeps a pair of of L-type screw chuck 3 mobile to track simultaneously, grip track, or simultaneously far from track.
L-type screw chuck 3 clamps that face is consistent with rail profiles, and when clamping is bonded completely, reaches reliable grip, and with anti-tipping function
Energy.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
