Description

Lifting coil plate automatic fixture

The utility model relates to a kind of employed a kind of lifting coil plate automatic fixture of roll bending of moving.

Traditional type roll bending lifting grasps anchor clamps, comprises substantially and decides arm plate and swing arm plate, and described swing arm plate is shape in obtuse angle, the knuckle place of this swing arm plate be provided with rotating shaft and an end of deciding the arm plate that is rectangular in shape mutually pivot close.During use, draw back two arm plates, the lower clip arm of swing arm plate is placed in the cavity of roll bending, the power that utilizes hoist cable to provide lifts the upper clip arm of swing arm plate, the lower clip arm of swing arm plate is just drawn close clamping to the lower clip arm of deciding the arm plate like this, thereby a sidewall of clamping roll bending is sling.When taking out anchor clamps, the hoist cable that needs the operating personnel to remove on the swing arm plate is linked up with, and is suspended on the lifting hole(eyelet) of deciding the arm plate, opens hoist cable power, and anchor clamps and roll bending are broken away from.This kind stone tongs uses convenient inadequately, need remove the hoist cable of seting out by manpower when transporting goods, the labour intensity height, and inefficiency also exists a safety control problem simultaneously.Therefore, this stone tongs has not satisfied job requirements.

The purpose of this utility model provides a kind of job safety, a kind of lifting coil plate automatic fixture of increasing work efficiency of guaranteeing.

The utility model is to realize like this, a kind of lifting coil plate automatic fixture, comprise and decide arm plate and swing arm plate, described swing arm plate is shape in obtuse angle, the knuckle place of this swing arm plate be provided with rotating shaft and an end of deciding the arm plate that is rectangular in shape mutually pivot close, it is characterized in that: be connected with two against clip wheel by bearing pin between two lateral walls of described swing arm plate bottom, the upper end is hinged with the guiding boatswain chair that has barb, be inlaid with the retaining clamping plate between described two lateral walls of deciding arm plate bottom, top is provided with a touching grab element, described touching grab element, comprise a barb-type hook plate and a spacing gusset that has hypotenuse, described hook plate and spacing gusset have round pin and welding manner to be fixed on respectively to decide between two lateral walls of the horizontal jig arm shoulder in the arm plate.Described retaining clamping plate comprise a clamp, and the back of clamp is connected with the connecting panel of a setting, and this connecting panel is provided with the translation hole, are fixed in by bolt in two lateral walls of deciding the arm plate, and the clamping surface of described clamp is provided with transversely arranged anti-skidding cognate.Described outside face indention against clip wheel.

The utility model mainly is to adopt the swing arm plate to stride frame mode outward, and will touch the grab element and be embedded between two lateral walls deciding arm plate top, makes full use of the anchor clamps space, avoids the impact of outer bound pair parts, and is not fragile.The utility model effectively utilizes the regularity of distribution of conducting oneself with dignity between power that crane fall provides and each parts, making the power that acts on the guiding boatswain chair that has barb drive obtuse angle shape swing arm plate swings around the rotating shaft anticlockwise direction, what thereby the lower clip arm shoulder that impels the swing arm plate was installed moves against clip wheel, realizes the anchor clamps closure.Described guiding boatswain chair is that the overhead kick that utilizes the characteristics of motion of hoist cable will lead on the boatswain chair directly imports colluding in the plate of touching grab element.

The utility model compared with prior art has following advantage: can shorten cycle of operations, improve operating efficiency, not need the operating personnel to hang and pluck suspension hook, it not only can reduce the operating personnel, reduce labour intensity, and can realize that people's goods separates, and guarantees operating personnel's personal safety.

Drawing is described as follows:

Fig. 1 is that the utility model master looks scheme drawing.

Fig. 2 is that Fig. 1 left side is looked and partly cutd open structural representation.

Below in conjunction with accompanying drawing the utility model is done further narration.

Referring to Fig. 1.From accompanying drawing as can be seen, the utility model comprises that square decides arm plate 14 and obtuse angle shape swing arm plate 5, the knuckle place of this swing arm plate 5 is provided with rotating shaft 3 and closes with the terminal pivot mutually of the horizontal jig arm shoulder 11 of deciding arm plate 14, the described lower clip arm 21 of deciding arm plate 14 and swing arm plate 5,2 are respectively equipped with retaining clamping plate 20 and against clip wheel 1, the end of the upper clip arm shoulder 13 of described swing arm plate 5 is hinged with the guiding boatswain chair 12 that has barb 9, described middle part of deciding the horizontal jig arm shoulder 11 of arm plate 14 be provided with one with the boatswain chair 12 that leads on the touching grab element 8 that can thread off of barb 9, this touching grab element 8 comprises hook plate 6 and spacing gusset 10 that has hypotenuse of a barb-type, described hook plate 6 and spacing gusset 10 are fixed on the middle part of the horizontal jig arm shoulder 11 of deciding arm plate 14 respectively with round pin 7 and welding manner, the neck of hook end of described hook plate 6 is connected with a bevelled guide plate 4.During lifting, the lower clip arm shoulder of swing arm plate 5 falls in the centre hole of roll bending, when goods is run into guide plate 4 on the hook plate 6, this hook plate 6 is just done clockwise direction around round pin 7 and is rotated, hook plate 6 and the barb 9 on the guiding boatswain chair 12 are thrown off, two lower clip arms shoulders 2,21 are drawn close roll bending grasped by the effect of power on the guiding boatswain chair 12 and moved.During unloading, the barb 9 of guiding on the boatswain chair 12 imports naturally and colludes on the plate 6 and be interlocked, and boatswain chair 12 these anchor clamps that lead at this moment sling are just thrown off with roll bending.Described retaining clamping plate 20, comprise a clamp 16, transverse row is shown anti-skidding cognate on the clamping surface 15 of this clamp 16, and make imploded arcs, be beneficial to fasten with the roll bending external diameter, the back central authorities of described clamp 16 are welded with the connecting panel 18 of a setting, and this connecting panel 18 is provided with two translation holes 17, and are fixed on the lower clip arm shoulder 21 of deciding arm plate 14 by bolt 19.Referring to Fig. 2, as can be seen from Figure, describedly be provided with two against clip wheel 1, be at 2 by folder, can make roll bending reach preferable counterbalance effect, these two cylindricals against clip wheel 1 are provided with is convenient to sawtooth promptly, and makes outer convex arc, so that fasten with the roll bending inner round wall, described two are fixed in two lateral walls 22,23 of swing arm plate by bearing pin 24 against clip wheel 1.Described touching grab element 8 is installed between two lateral walls 25,26 of deciding the arm plate.The utility model all is arranged on the critical component of action in the centre joint of anchor clamps, can avoid the damage of outer bound pair parts like this, and maintenance capacity is little, thereby can reach the purpose of time-saving and efficiency.
