Abstract
The utility model discloses a low-noise electric single-beam crane comprising a main beam. The main beam is installed between two end beams; an operating cabin is arranged below one side of the main beam; a variable-frequency electric hoist is installed on the main beam and connected with a hoisting mechanism and an operating mechanism; a variable-frequency speed control system is arranged on one end beam of the crane and connected with the variable-frequency electric hoist; the main beam comprises a box body consisting of a middle section with an integrally formed structure, and two closing ends; two connecting webs are respectively welded on the two sides of the box body; the top parts of the two connecting webs are splayed and are fixed with a steel rail in a welding manner; and the two connecting webs are of an integrally formed structure. The low-noise electric single beam crane is stable in braking and reduces noises in operation, a brake effect of a grab bucket of the crane is greatly improved, the vibration of the grab bucket in braking is small, and maintenance load is reduced greatly.
Description
Technical field
The utility model belongs to the crane facility field, is specifically related to a kind of low-noise electric single-beam crane.
Background technology
Single-beam crane has that oad compactness, building clear headroom are low, the workshop that is widely used in the industries such as machine manufacture workshop, metallurgical plant, oil, petrochemical industry, harbour, railway, civil aviaton, power station, papermaking, building materials, electronics from heavy and light, the little advantage of wheel load, warehouse, stock ground etc.
The girder of single-beam crane adopts the multistage assembly unit to be welded usually at present, owing to adopting the multistage assembly unit to be welded, the girder that this assembly unit is welded tends to produce local deformation, make its precision be difficult to control, cause hoisting crane not steady when the grab bucket braking, shake during braking greatly, during the hoisting crane operation, noise is large.In addition, the electric drive system of existing single-beam crane is generally the interchange wound-rotor motor, adopt the mode of rotor crosstalk resistance to start and speed governing, when the mode of this rotor crosstalk resistance causes the hoisting crane operation, vibration is large, frequent operation, rush current is large, and motor and the crosstalk resistance of rotor institute burn out and even the fault that ruptures happens occasionally, cause maintenance capacity large, directly and the indirect maintenance cost high.
The utility model content
Technical problem to be solved in the utility model is to provide the low-noise electric single-beam crane that a kind of deceleration and stopping performance is steady, can effectively reduce fault rate.
for solving the problems of the technologies described above, a kind of low-noise electric single-beam crane of the utility model, comprise main beam, described main beam is arranged between the end carriage at two ends, control cabin is positioned at the below of described main beam one side, be arranged on described main beam with the frequency conversion electric block that lifting mechanism is connected with operating unit, the end carriage of described hoisting crane is provided with frequency conversion speed-adjusting system, this frequency conversion speed-adjusting system is connected with the frequency conversion electric block, described main beam comprises box body, described box body is made of the closing in termination at the interlude of integral forming structure and two ends, described box body both sides are welded with respectively one and connect web, two tops that connect web are splayed and are welded and fixed mutually with rail, described two connection webs are integral forming structure.
Compared with prior art, the beneficial effects of the utility model are: the box body of the utility model main beam be connected web and be integral forming structure, reduced the distortion of main beam of single-beam crane in handling process, when having guaranteed the hoisting crane operation, braking steadily, has reduced noise; Simultaneously, the utility model adopts frequency conversion speed-adjusting system, can greatly improve the grab bucket braking effect of hoisting crane, during the grab bucket braking vibrations little, greatly reduce maintenance load, saved maintenance cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of low-noise electric single-beam crane of the utility model;
Fig. 2 is the structural representation of main beam of the present utility model;
Fig. 3 is that Fig. 2 is at the cutaway view at A-A place.
The specific embodiment
as Fig. 1, Fig. 2 and shown in Figure 3, a kind of low-noise electric single-beam crane, comprise main beam 2, described main beam 2 is arranged between the end carriage 5 at two ends, control cabin 3 is positioned at the below of described main beam 2 one sides, be arranged on described main beam 2 with the frequency conversion electric block 1 that lifting mechanism is connected with operating unit, the end carriage 5 of described hoisting crane is provided with frequency conversion speed-adjusting system 4, this frequency conversion speed-adjusting system 4 is connected with frequency conversion electric block 1, described main beam 2 comprises box body 21, described box body 21 is made of the closing in termination 25 at the interlude 24 of integral forming structure and two ends, described box body 21 both sides are welded with respectively one and connect web 22, two tops that connect web 22 are splayed and are welded and fixed mutually with rail 23, described two connection webs 22 are integral forming structure.
The box body 21 of the utility model main beam 2 be connected web 22 and be integral forming structure, reduced the distortion of main beam of single-beam crane in handling process, when having guaranteed the hoisting crane operation, braking steadily, has reduced noise; Simultaneously, electric drive system of the present utility model adopts frequency conversion speed-adjusting system, can greatly improve the grab bucket braking effect of hoisting crane, during the grab bucket braking vibrations little, greatly reduce maintenance load, saved maintenance cost.
