Abstract

The utility model relates to a lifting and unloading device which comprises steel wire ropes (4), a coiled plate (5), and right-angle stress protectors (6). The lifting and unloading device is used for weight lifting and unloading. Each of the right-angle stress protectors (6) comprises a concave rib plate (3), right angle plates (2), and an elbow (1), and is assembled and welded with a round elbow and a steel angle. The lifting and unloading device has the advantages that the right angle stress of the steel wire ropes (4) is changed into an arc stress through the stress protectors, crushing and wear are avoided, safety operation in the process of weight lifting and unloading is guaranteed, and each of the steel wire ropes (4) of the protectors can be used for about 1000 times, and therefore the service life of the steel wire ropes is greatly prolonged.

Description

A kind of hoist device

Technical field

The utility model relates to a kind of hoist device, especially is applicable to the hoist device of weight loading and unloading.

Background technology

In the industrial and mining enterprises, the hoist device instrument that is absolutely necessary, in the prior art, the hoist device of commonly using all is to adopt the stressed method in right angle, namely directly steel cable is enclosed within on the roll bending, steel cable in the unloading process because two right angles are concentrated stressed, steel cable weighs wounded at the place, right angle, wear pattern is serious, and potential safety hazard is very large, and this method unloading, a steel cable uses and is no more than 200 times, and service life is shorter.

In a word, along with the gradually raising of people to the requirement of commercial production energy-saving safe, so need to have the structure of the hoist device of many defectives to improve to above-mentioned, thereby a kind of new safety is good, easy to maintenance, the invention of long service life, utility model hoist device that practicality is high is imperative.

The utility model content

Technical problem to be solved in the utility model provides a kind of hoist device, solve that traditional steel cable easily weighs wounded, easy to wear, potential safety hazard is large, the short problem in service life of steel cable, be exclusively used in the hoist device of the roll bending that weight is larger in industrial and mining enterprises' weight loading and unloading.

The technical scheme that the utility model solves the problems of the technologies described above is as follows:

1, a kind of hoist device comprises steel cable (4), roll bending (5), the stressed protector in right angle (6); described roll bending (5) is cube; described right angle Force receiver (6) has two; be separately fixed at the inboard hollow position in roll bending (5) bottom surface, two ends, steel cable (4) is tightly placed in the stressed protector in described right angle (6).

2; the stressed protector in described right angle (6) comprises two spill gussets (2); a L-square (3) and an elbow (1); described elbow (1) is made the pipe of the turning of 90 degree for pipeline; the female end of described two spill gussets (2) is the nested position that is fixed on the close bottom surface of the inflexed side of elbow (1) respectively; described two spill gussets (2) have respectively one right angle end; and link to each other with two square edges of described L-square (3); the intersection place of two square edges of described L-square (3) is fixed on the inboard midway location of elbow (1); and one side of described L-square (3) is fixed on roll bending (5) bottom surface near the place, inside edge of hollow, and another side is fixed on roll bending (5) bottom surface.

3, in the stressed protector in described right angle (6), all adopt the angle steel assembly welding to be connected between two spill gussets (2) and L-square (3), two spill gussets (2) and elbow (1) and L-square (3) and the roll bending (5).

Increased scheme drawing such as Fig. 1 behind the stressed protector in right angle (6), the stressed protector in right angle (6) utilizes elbow (1) and angle steel assembly welding.Steel cable (4) is by the stressed protector in right angle (6), and changing the right angle stressed is that circular arc is stressed, has avoided weighing wounded and wearing and tearing, and can ensure to greatest extent the safe operation of weight unloading, and prolongs the service life of steel cable (4).

The beneficial effects of the utility model are:

1, increased the stressed protector in right angle in the hoist device after; steel cable is by the stressed protector in right angle; changing the right angle stressed is that circular arc is stressed; avoided weighing wounded and wearing and tearing; can ensure the safe operation in the weight unloading process; reduce potential safety hazard, and one of the steel cable of protector can be used about 1000 times, prolonged the life-span greatly.

2, the angle steel assembly welding is all adopted in the connection between each position of the stressed protector in right angle, and is light and handy nimble and sturdy and durable, so that product junction welding insulation, make the junction more fastening, and can prevent oxidation, plays the effect that beautifies outward appearance.

Description of drawings

Fig. 1 is the integral structure scheme drawing of the utility model hoist device;

Fig. 2 is lateral plan (left side) and the front view (right side) of the stressed protector in the utility model right angle;

Fig. 3 is the structural representation of L-square in the stressed protector in right angle.

In the accompanying drawing, the list of parts of each label representative is as follows:

1, elbow, 2, L-square, 3, the spill gusset, 4, steel cable, 5, roll bending, 6, the stressed protector in right angle.

The specific embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.

As shown in Figure 1; after roll bending (5) has been installed the stressed protector in right angle as shown in Figure 2 (6); steel cable (4) is tightly placed on the stressed protector in right angle (6); subsequently; starting hoist device slings weight; in this process; stressed to be converted into circular arc stressed with the right angle by the stressed protector in right angle (6) for steel cable (4); so that steel cable (4) has been avoided wearing and tearing and has been weighed wounded; after hoist device is delivered to the destination with weight, weight is put down, efficient and convenient; and reduced labour intensity, improved working security.Owing to avoided weighing wounded and wearing and tearing by steel cable (4) after improving, so that the life-span of steel cable (4) improves greatly, so reduced service expenditure, shortened construction period, guarantee construction speed and construction quality, reduced construction cost.

The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
