Abstract
The utility model relates to a back pressure type anti-falling steel plate sling clamp, wherein a cross section of which is a clamp body in a tiger mouth shape, an upper clamp mouth of the clamp body has a fork structure, and the end of the upper clamp mouth is connected with a press bolt which is in a long bolt shape and is arranged between two fork arms of the fork structure; the upper left corner of the press bolt in the long bolt shape is provided with a pin shaft hole, and the upper right corner of the press bolt in the long bolt shape is provided with a hoisting hole; the left straight edge of the press bolt in the long bolt shape is provided with a handrail. The back pressure type anti-falling steel plate sling clamp of the utility model which is suitable for slinging steel plates in various specifications has the characteristics of falling prevention, large clamping force and safety.
Description
Technical field
The utility model belongs to steel plate loading and unloading accessory appliances, particularly a kind of back pressure type anticreep steel plate tongs.
Background technology
The steel plate tongs is the common tool that is used for hoisting steel plate, is made up of caliper and pressure tongue.During use the pressure tongue of tongs is opened, with the below that caliper is placed steel plate, utilized caliper and press tongue to clamp the steel plate that will lift by crane, lifting is connected the hoist cable of pressing on the tongue again, has so just realized the lifting of steel plate.Caducous problem when present employed steel plate tongs exists lifting must buttress tongs by operating personal before the lifting, otherwise tongs comes off very easily and causes the accident.The major cause that causes the steel plate tongs to come off in use: 1, using the steel plate tongs when clamping steel plate, at this moment, the hoisting point position of pressing tongue is in the outside at steel plate edge, both in the steel plate tongs bearing pin outside of (connecting caliper and the bearing pin of pressing tongue).Because the main weight of steel plate tongs all concentrates on the caliper, press the tongue suspension centre to link to each other with hoist cable again, so, the increasing of operating personal operation easier, and at the beginning the steel plate tongs caliper just can't with steel plate well realization face contact.2, owing to press the outside of the hoisting point position of tongue at the steel plate edge, so, when steel plate lifted by crane, the caliper of steel plate tongs and the stress point of steel plate were a line at steel plate edge, that is to say that the steel plate tongs can not vise steel plate all the time securely in the hoisting process of steel plate.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of back pressure type anticreep steel plate tongs is provided.Do not need operating personal to buttress tongs before the lifting, and have slip-off preventing, folder power is big, safe and reliable.
The technical solution of the utility model is:
A kind of back pressure type anticreep steel plate tongs, it is characterized in that: a section is a tiger clamp body, the upper jaw of caliper is a fork configuration, connect shape fond of gossip in the upper jaw end by bearing pin and press tongue, shape fond of gossip presses tongue to be contained between two yokes of upper jaw fork configuration, it is pin shaft hole that shape fond of gossip is pressed the upper left corner of tongue, and it is hole for hoist that shape fond of gossip is pressed the upper right corner of tongue.
On the left straight flange of shape pressure tongue fond of gossip, be connected with handrail.
The utility model effect is:
Use the utility model back pressure type anticreep steel plate tongs, it is applicable to the lifting of all size steel plate, has slip-off preventing, big, the safe and reliable characteristics of folder power.

The specific embodiment
A kind of back pressure type anticreep steel plate tongs shown in Fig. 1,2, a section is the caliper 1 of tiger shape (ㄈ shape), the upper jaw of caliper is a fork configuration, connect shape fond of gossip (long D shape) in the upper jaw end by bearing pin 3 and press tongue 2, shape fond of gossip presses tongue to be contained between two yokes of upper jaw fork configuration, it is pin shaft hole that shape fond of gossip is pressed the upper left corner of tongue, and it is hole for hoist 4 that shape fond of gossip is pressed the upper right corner of tongue.
On the left straight flange of shape pressure tongue fond of gossip, be connected with handrail 5.
The back pressure type anticreep steel plate tongs that is to use shown in Figure 3 lifts the steel plate operation, adopts four back pressure type anticreep steel plate tongs, and hole for hoist 4 is put on hoisting wirerope and carried out lifting operation.
This back pressure type anticreep steel plate tongs is to change shape and the hoisting point position that existing steel plate tongs is pressed tongue, hoisting point position is changed into the steel plate tongs bearing pin opposite side promptly inboard (Fig. 3) of (connecting caliper and the bearing pin of pressing tongue), make position that the steel plate tongs presses the tongue suspension centre in use all the time in the inboard at steel plate edge, at this moment, owing to press the effect of tongue and deadweight, the steel plate tongs can be clamped on steel plate at the very start securely.After the lifting, press tongue suspension centre one end to mention, the tongue body position back-pressure of pressing tongue makes caliper keep good face to contact with steel plate all the time on steel plate, has solved the difficult problem that former steel plate tongs easily comes off in use and can't contact with steel plate realization face in the lifting process with caliper fully.Simultaneously,, on the pressure tongue of back pressure type anticreep steel plate tongs, installed portable, made its operation of being more convenient for for ease of the operating personal operation.
Claims (2)
1, a kind of back pressure type anticreep steel plate tongs, it is characterized in that: a section is a tiger clamp body, the upper jaw of caliper is a fork configuration, connect shape fond of gossip in the upper jaw end by bearing pin and press tongue, shape fond of gossip presses tongue to be contained between two yokes of upper jaw fork configuration, it is pin shaft hole that shape fond of gossip is pressed the upper left corner of tongue, and it is hole for hoist that shape fond of gossip is pressed the upper right corner of tongue.
2, back pressure type anticreep steel plate tongs according to claim 1 is characterized in that: be connected with handrail on the left straight flange of shape pressure tongue fond of gossip.
