Abstract

The utility model relates to a lifting tool used in the fields of machining and in particular relates to a Lamar type externally circular lifting appliance. The Lamar type externally circular lifting appliance comprises a lifting rod, wherein the lower end part of the lifting rod is fastened with a connection seat through nuts; a lifting lug is arranged at the upper end of the lifting rod; a grabber seat is arranged on a middle rod body of the lifting rod in a sliding manner; a spring is arranged on the lifting rod in a sleeved manner; the upper end of the spring is limited through a first nut on the lifting rod; the lower end of the spring presses against the upper end face of the grabber seat; the grabber seat is connected with grabbers in a rotatable manner through pin shafts and opening pins; one ends of connection plates are connected to the connection seat in a rotatable manner, and the other ends of the connection plates are connected to the middle parts of the grabbers in a rotatable manner. The Lamar type externally circular lifting appliance is suitable for lifting of front covers of planetary speed reducers with different sizes and is high in lifting efficiency.

Description

La Mashi excircle sling

Technical field

The utility model relates to a kind of lifting device for field of machining, is a kind of La Mashi excircle sling specifically.

Background technology

At present, large planetary reductor protecgulum is generally the bowl-shape part of taper, not only volume is large but also quality weight, add and with standard suspender, be difficult to lifting man-hour, cause existing a lot of problems in the process of machinework volume production, main manifestations is: one, a dead lift consumes huge muscle power, and loses time, and has had a strong impact on production efficiency; Two, adopt bottom outlet to insert rod iron, then with suspension hook, lift, be not only not easy operation, and have very large potential safety hazard, efficiency is extremely low in addition.Therefore,, in volume production process, need to design special excircle sling and enhance productivity.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of La Mashi excircle sling simple in structure, ingenious, rational is provided, and this suspender is applicable to the protecgulum of hoisting large-size planetary reducer, and lifting efficiency is high.

The technical scheme providing according to the utility model: a kind of La Mashi excircle sling, it is characterized in that: comprise suspension rod, there is Connection Block described suspension rod bottom by fastening nuts, suspension rod upper end has hanger, claw hook seat slides and is arranged on the body of rod of suspension rod middle part, on suspension rod, be also set with spring, described spring upper end is spacing by the first nut on suspension rod, spring lower end holds out against in claw hook seat upper surface, on described claw hook seat, by bearing pin and spring cotter, be rotationally connected claw hook, connecting panel one end is rotationally connected with on Connection Block, and the other end is rotationally connected with claw hook middle part.

As further improvement of the utility model, on described claw hook seat, there are three claw hook mounting grooves, and three along the circumferential direction uniform settings of claw hook mounting groove, on Connection Block corresponding to being provided with under mounting groove for connecting panel installing handle is installed.

The utility model compared with prior art, advantage is: the utility model is applicable to lift the protecgulum of the large planetary reductor of different size, by suspender and travelling crane hook adapted, and by pulling hanger to adjust claw hook openings of sizes, make suspender be applicable to the lifting of different-diameter cylindrical part, easy to use, range of use is wide, work efficiency in the time of can effectively improving reductor protecgulum volume production, avoid in line flow procedure due to employee turnover, or the problems such as the production of the general generation of suspender is defaulted, spring is also housed on this suspender, during use, can auto lock, without potential safety hazard.

Accompanying drawing explanation

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

Fig. 2 is the left view of Fig. 1.

The specific embodiment

Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, comprise hanger 1, suspension rod 2, claw hook seat 3, Connection Block 4, claw hook 5, spring 6, the first nut 7, connecting panel 8, bearing pin 9, spring cotter 10, protecgulum 11 etc.

As Fig. 1, shown in Fig. 2, the utility model is a kind of La Mashi excircle sling, comprise suspension rod 2, there is Connection Block 4 described suspension rod 2 bottoms by fastening nuts, suspension rod 2 upper ends have hanger 1, claw hook seat 3 slides and is arranged on the suspension rod 2 middle part bodies of rod, on suspension rod 2, be also set with spring 6, described spring 6 upper ends are spacing by the first nut 7 on suspension rod 2, spring 6 lower ends hold out against in claw hook seat 3 upper surfaces, on described claw hook seat 3, by bearing pin 9 and spring cotter 10, be rotationally connected claw hook 5, connecting panel 8 one end are rotationally connected with on Connection Block 4, the other end is rotationally connected with claw hook 5 middle parts.

On described claw hook seat 3, there are three claw hook mounting grooves, and three along the circumferential direction uniform settings of claw hook mounting groove, on Connection Block 4 corresponding to being provided with under mounting groove for connecting panel 8 installing handles are installed.

Working process of the present utility model is as follows: when needing the protecgulum 11 of hoisting large-size planetary reducer, first hanger 1 is pressed down, hanger 1 drives suspension rod 2 to move down in moving downward process, three claw hooks 5 on claw hook seat 2 are strutted in protecgulum 11 outer rim places, then make hanger 1 upward movement until claw hook 5 lower end hook portions are hooked protecgulum 11, then with travelling crane hook, part is sling, hung on platen.
