Specific embodiment

The present invention will be further explained below with reference to the attached drawings.

A kind of specific structure of the counterweight frame of having electronic lifting safety tongs of the invention is as shown in Figures 3 to 8, including counterweight Frame 2, counterweight frame 2 include underbeam 21 and vertical beam 22, and counterweight guide shoe 4, the lower section installation of underbeam 21 are equipped on the vertical beam 22 of two sides There is counterweight buffer pedestal 5.Underbeam 21 be box beam, inside safety tongs linkage mechanism is installed, safety tongs linkage mechanism Both ends are equipped with safety tongs 1, and safety tongs 1 is stretched out in underbeam 21 with with counter weight guide track, safety tongs linkage mechanism is used for band The safety tongs 1 of dynamic two sides moves synchronously.

Safety tongs linkage mechanism includes safety tongs lifting plate 7, installation axle 8, interlocking bar 9, reset spring 10,11 and of electromagnet Hypervelocity monitoring and control module 12.Installation axle 8 has two, and the both ends of underbeam 21 are symmetrically mounted at relative to underbeam 21, safety Pincers lifting plate 7 is mounted in installation axle 8 in middle part and can center axis thereof relative to lower beam body 21 around corresponding installation axle 8. Safety tongs lifting plate 7 can be both fixed in installation axle 8, installation axle 8 can also be fixed on underbeam 21, be lifted safety tongs Plate 7 is installed in rotation in installation axle 8.The outer end of safety tongs lifting plate 7 extends outward the connecting plate 71 of underbeam 21, safety Pincers 1 are mounted on the end of connecting plate 71.Interlocking bar 9 is in tilted layout between two blocks of safety tongs lifting plates 7.

Connection structure between safety tongs 1 and connecting plate 71 is specifically described as follows: offering length in the end of connecting plate 71 The long hole 73 of the length direction along underbeam 21 is spent, safety tongs 1 is mounted in the long hole 73 by bolt, and bolt can be along long hole 73 length direction is mobile, can lift safety tongs 1 vertically when guaranteeing that safety tongs lifting plate 7 rotates.In other examples, Other connection structures can also be used between safety tongs 1 and connecting plate 71 to guarantee that safety tongs 1 is lifted vertically.

Specifically: being provided with connecting shaft 72 on the safety tongs lifting plate 7 of two sides, and wherein connecting shaft 72 of left side It is located at the lower end that dextral safety pincers mention a plate 7, the both ends of interlocking bar 9 in the upper end of safety tongs lifting plate 7, the connecting shaft 72 on right side It is separately mounted in corresponding connecting shaft 72.In other examples, interlocking bar 9 can also be mounted on using other modes Full pincers mention on a plate 7.Interlocking bar 9 can both be fixed together with safety tongs lifting plate 7, can also be installed in rotation on connection On axis 72, as long as two pieces of safety tongs lifting 7 synchronous shifts of plate can be driven.

In a more preferred embodiment, interlocking bar 9 includes two quarter butts being cascaded by long nut 91.It is two short Bar is threadably mounted at the both ends of long nut 91, and the total length of interlocking bar 9 is adjusted by long nut 91, reduces to machining accuracy It is required that.It is understood that in other embodiments, interlocking bar 9 is also possible to the uncontrollable bar of length, at this time interlocking bar 9 It can be other structures.

Overspeed detection and control module 12 are used to detect the decrease speed of counterweight frame 2, electromagnet 11 and overspeed detection and control Molding block 12 is conductively connected, when overspeed detection and control module 12 detect the decrease speed of counterweight frame 2 more than setting speed, Overspeed detection and control module 12 are to the sending trigger signal of electromagnet 11, and electromagnet 11 is triggered electric, and moving armature 11-1 is inhaled It closes and is moved towards the main paragraph 11-2 of electromagnet 11.Overspeed detection and control module 12 are product in the prior art, tool Where body structure and not this Applicant's Abstract graph improvement, its structure is no longer discussed in detail in the application.Electromagnet 11 is located at the upper of interlocking bar 9 Side, moving armature 11-1 are fixed on the upper end of the safety tongs lifting plate 7 on right side, when moving armature 11-1 is moved downward, the peace on right side Pincers lifting plate 7 inwardly rotates counterclockwise and the safety tongs 1 on right side is driven above to mention entirely, and the interlocking bar 9 of measured length will pull left side Safety tongs lifts plate 7 and drives the safety tongs 1 in left side to synchronize therewith inwardly rotating clockwise and above mention.The safety tongs 1 of two sides is synchronous Above mentioned and can stop counterweight frame.

The middle part of underbeam 21 is provided with two pieces of blocks 23, and interlocking bar 9 passes through two pieces of blocks 23, and reset spring 10 is sleeved on two In interlocking bar 9 between block block 23, the right end of reset spring 10 abuts with right side block 23, is in left end and interlocking bar 9 convex Block abuts, to push interlocking bar 9 to reply home position after 11 power loss of electromagnet, to drive safety tongs lifting plate 7 and safety Pincers 1 reply home position.

In other embodiments, the safety tongs of the positional relationship and fixed moving armature 11-1 of electromagnet 11 and interlocking bar 9 It is alterable to lift plate 7, it is only necessary to safety tongs can be driven to lift plate 7 when electromagnet 11 obtains electric by moving armature 11-1 and inwardly rotated To drive safety tongs 1 above to mention；Safety tongs lifting plate 7 can be other structure types.

Finally, it is stated that: the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, this field is common Other modifications or equivalent replacement that technical staff makes technical solution of the present invention, without departing from technical solution of the present invention Spirit and scope, be intended to be within the scope of the claims of the invention.
