Description

A kind of ultrahigh pump lift electric block

Technical field

The utility model relates to a kind of ultrahigh pump lift electric block.

Background technology

Traditional electric block all is to adopt single drum winding of single layer structure, and multiplying power is 2/1,4/1,4/2 etc.In order to increase the lifting altitude of electric block, can adopt the measures such as double-deck winding, increase drum diameter, increase reel length, but this several method there are a lot of shortcomings.At first, the method for multiple wraps is had relatively high expectations to the manufacturing of roll device, and end face has increased reverse link in the reel left and right sides, and steel rope crank motion on reel carries out bilayer and twines, and have to change rope guide into rope processing device.Owing to there not being rope guide, circuit fire stop is not used, can only be spacing with the travel switch limit that rises, and lacked the falling-threshold limit function, and safety is reduced, simultaneously large because of manufacture difficulty again, steel rope is easy to wear, also can adopt broken line reel effectively to realize multiple wraps, but this reel is difficult for processing, cost is high, also can causes the rope guide can't Matching installation and be difficult to be used widely.

Secondly, the method that increases drum diameter improves the rising or falling speed of electric block, the reel moment of torsion strengthens, motor power (output) originally and all out of reach requirements of retarder moment of torsion need the parts such as redesign tween drive shaft, coupler, rope guide, roll device, make manufacturing cost too high, component universality is poor, and owing to strengthening drum diameter, cause the suspension hook upper limit excessive, might the out of reach field requirement.If replace little tonnage with large-tonnage, be high cost equally, and the lifting altitude increase is not remarkable.Have again, increase the restriction that reel length is subject to oad and tween drive shaft.The increase of reel length is too large, affects electric block at the limit size at track two ends, hangs the weight less than two ends, and brings difficulty to processing.Long tween drive shaft rigidity is relatively poor, during High Rotation Speed the vibration excessive, be prone to and take off axle and breaking axis.In sum, three kinds of methods that increase the electric block lifting altitude are all undesirable.

The utility model content

The purpose of this utility model provides a kind of ultrahigh pump lift electric block, overcomes in the existing product to cause cost of product too high by improving lifting altitude the deficiency that safety is low.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of ultrahigh pump lift electric block, comprise carriage, two ends, carriage top are fixedly connected with motor-driven carrier by link span respectively, the motor-driven carrier joining rails, the below of described carriage one side is fixedly connected with the reel shell, reel shell one side is provided with motor, another side of reel shell is provided with retarder, be provided with the reel with non-rotating cable in the reel shell, one end of non-rotating cable is connected with the rope wedge, and the rope wedge is connected with lifting beam with hook one by adapter shaft, and lifting beam with hook one below is provided with lifting beam with hook two, lifting beam with hook two is connected with suspension hook, and lifting beam with hook one and lifting beam with hook two are captiveed joint by connecting panel.

Further, described adapter shaft, suspension hook are connected with lifting beam with hook one, lifting beam with hook two respectively by hook nut, are equipped with the surface bearing that matches on adapter shaft, the suspension hook.

Further, the inside of described carriage opposite side is provided with weight box.

Further, described non-rotating cable is tangent sagging and overlap with orbit centre along the reel cylindrical.

The beneficial effects of the utility model are: a kind of ultrahigh pump lift electric block that the utility model provides, adopt the structure design of unit structure, so that complete machine is not only compact small and exquisite but also satisfy the forced stroke that sling height is 110m, and weight does not rotate after being lifted to the high-altitude, and simple in structure, cost is low.

Description of drawings

The below is described in further detail the utility model with reference to the accompanying drawings.

The specific embodiment

As Figure 1-3, the described a kind of ultrahigh pump lift electric block of the utility model embodiment, comprise carriage 1, two ends, carriage 1 top are fixedly connected with motor-driven carrier 3 by link span 2 respectively, motor-driven carrier 2 joining rails 4, the below of described carriage 1 one sides is fixedly connected with reel shell 5, reel shell 5 one sides are provided with motor 6, reel shell 5 another sides are provided with retarder 17, be provided with the reel with non-rotating cable 7 in the reel shell 5, one end of non-rotating cable 7 is connected with rope wedge 16, rope wedge 16 is connected with lifting beam with hook 1 by adapter shaft 8, lifting beam with hook one 9 belows are provided with lifting beam with hook 2 10, and lifting beam with hook 2 10 is connected with suspension hook 11, and lifting beam with hook 1 is captiveed joint by connecting panel 12 with lifting beam with hook 2 10.Described adapter shaft 8, suspension hook 11 are connected with lifting beam with hook 1, lifting beam with hook 2 10 respectively by hook nut 13, are equipped with the surface bearing 14 that matches on adapter shaft 8, the suspension hook 11.The inside of described carriage 1 opposite side is provided with weight box 15.Described non-rotating cable 7 is tangent sagging along the reel cylindrical, with track 4 center superpositions.

The ultrahigh pump lift electric block that the utility model provides, on common electric cucurbit basis, change original 2/1 multiplying power into 1/1 multiplying power, measure rise by original appearance rope and approximately reach original 2 times, by adding long carriage lifting altitude is improved on its basis simultaneously.Because former 5 ton of 2/1 multiplying power is the duplex type hoisting heavy, its wirerope diameter is 16mm, it now is single rope lifting, wirerope diameter need overstriking to the nominal tensile strength of 18mm or raising steel rope to 1960Mpa then wirerope diameter may be selected to be 14mm, and adopt non-rotating cable 7 for avoiding producing torsion problem owing to steel rope is long, the fixed end of non-rotating cable 7 on suspension hook connects by surface bearing 14, suspension hook 11 can rotate freely can be with non-rotating cable 7 internal stresss, rotational force discharges, and the rotation direction of reel also can be played certain effect that prevents suspension hook 11 rotations with the opposite making of rotation direction of non-rotating cable 7.The reel shell 5 of electric block is connected on the carriage 1 fixing and by track 4 center arrangement relatively, make non-rotating cable 7 tangent sagging along the reel cylindrical, with track 4 center superpositions, such layout can make and guarantee whole balance of mechanism in hoisting heavy, and in zero load, realize balance by hidden weight box 15 in carriage 1, under two operating modes, all meet the mechanics requirement like this, also so that complete machine is compact, attractive in appearance.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
