Abstract

The utility model provides a deadweight automatic fixture, which is suitable for lifting and carrying large brick materials. The utility model is characterized in that four clamping arms are arranged, and one end of each of the clamping arms is provided with a clamping plate; the four clamping arms are respectively symmetrically and movably connected with a same clamping arm shaft; the other end of each of the four clamping arms are respectively movably connected with four drawing arms by two connecting shafts; the four drawing arms are movably connected with a same drawing arm shaft provided with a hanging ring. The utility model has the advantages of simple structure, small size, light weight, stable lifting, high safety and reliability, convenient operation, etc. and can not generate any damage to the edge angle and the plane surface of the brick materials.

Description

Deadweight automatic fixture

The utility model belongs to the masonry goods and promotes the carrying technical field, particularly lifts by crane a kind of anchor clamps of masonry goods.

In fields such as chemical industry, metal smelt, need in kiln, carry out sometimes, so must use some satisfactory as clay brick, bauxite brick and high diamond spar brick etc., the weight of brick by several kilograms to the hundreds of kilogram.Because the requirements for quality to brick is relatively stricter, especially oversize brick, so the particular importance that in the process of carrying, seems.At present, generally use spiral jackscrew anchor clamps or steel rope torque arm anchor clamps anchor clamps, then lifting as oversize brick.This anchor clamps use very inconvenient, and efficient is low, could lift by crane after having only rotary screw rod, and labour intensity is bigger, and very dangerous, once can't clip, not only damages the brick material, even human casualty accident can occur.

The purpose of this utility model is to provide a kind of anchor clamps of new construction, to solve the existing problem of above-mentioned anchor clamps.

The purpose of this utility model is achieved in that it has four to be the jig arm that end has clamping plate respectively, symmetrical respectively the living of this jig arm is connected on the same jig arm axle, the other end in these four jig arm is connected with four torque arm by two adapter shaft work respectively, and these four torque arm work are connected on the same torque arm axle that has suspension ring.Between jig arm and torque arm, be fixed with a suspension hook, on the jig arm axle, be symmetrically fixed with two liftable spacing equalizer bars.During use, these anchor clamps clamping plate are affixed on to be needed on the brick of the handling material sidewall, spacing by spacing equalizer bar, unloads suspension hook, starts to promote suspension hook and rise, and these anchor clamps just close arm automatically, get final product handling.

Characteristics such as the utlity model has simple in structurely, volume is little, and is in light weight, and lifting steadily, and is safe and reliable, easy to operate, these anchor clamps can not cause any damage to the corner angle and the plane of brick material in the handling process.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the lateral plan of Fig. 1.

Fig. 3 is a spacing equalizer bar structural representation of the present utility model.

Fig. 4 is a suspension hook structural representation of the present utility model.

Referring to Fig. 1～4, concrete structure of the present utility model is: have four one ends to have the jig arm 3 of clamping plate 1, these four jig arm, 3 two two symmetries are lived and are connected in the two ends of same jig arm axle 5, and living on two jig arm 3 of jig arm axle 5 homonymies has been connected on the balance shaft 4 of equilibrium activity.The other end in jig arm 3 is connected with four torque arm 7 by two adapter shafts, 6 symmetrical living respectively, and these four torque arm, 7 symmetries are lived and are connected in same two ends that have the torque arm axle 8 of suspension ring 9.On clamping plate 1 surface that contacts with the brick material, be fixed with a rubber pad 2; Between the balance shaft 4 of the same side and adapter shaft 6, be connected with a turning suspension hook of offing normal 10; On jig arm axle 5, evenly be fixed with two spacing equalizer bars 11 of lifting mode that have adjusting shaft 12.During use, the deadweight automatic fixture is placed on the brick material of required handling, rubber pad 2 is contacted with the sidewall of brick material, upset suspension hook 10 is offed normal it, starts suspension ring 9 and rises, and these anchor clamps just close arm automatically, and the brick material is sling reposefully.When the brick material moves into place, decline suspension ring 9, brick material steadily after with suspension hook 10 upset returns, lifting, anchor clamps are from the brick material from institute's handling, thereby have finished the purpose of this utility model.

Claims

1, a kind of deadweight automatic fixture that is used for handling oversize brick stone material, it includes clamping plate, jig arm etc., it is characterized in that having four respectively an end have the jig arm of clamping plate, symmetrical respectively the living of this jig arm is connected on the same jig arm axle, the other end four jig arm is connected with four torque arm by two adapter shaft work respectively, and these four torque arm work are connected on the same torque arm axle that has suspension ring.

2, deadweight automatic fixture according to claim 1 is characterized in that being fixed with a suspension hook between jig arm and torque arm.

3, deadweight automatic fixture according to claim 1 is characterized in that evenly being fixed with two liftable spacing equalizer bars on the jig arm axle.
