Abstract
The invention discloses an electric hoist device which at least comprises a drum assembly, a speed reducer, a three-in-one driving system, fixing parts, a rack, a lifting height limiter, a limit switch fixing seat, screws, a gasket and a lifting hook assembly, wherein the drum assembly is arranged at one end of the rack and is connected with the speed reducer; the speed reducer is connected with the three-in-one driving system; the fixing parts are respectively arranged on the left side and the right side of the rack; the lifting height limiter is arranged at the front end of the limit switch fixing seat; the limit switch fixing seat is fixed on one side of the rack through the screws and the gasket; the lifting hook assembly is connected with the drum assembly through a bearing, a pulley and a steel wire rope. According to the electric hoist device, on the premise that lifting functions can be met, a limiter is supposed to be arranged on the original electric hoist device, so the limitation of the position is more accurate. The electric hoist device has the advantages of simple integral structure, high practicality, and high convenience for popularization and use.
Description
Technical field
The present invention relates to a kind of jack up unit, especially a kind of electric block device.
Background technology
Electric block is called for short hoist ceiling crane, is a kind of small-sized weight-lifting equipment.Most electric block uses button to follow manipulation on ground by people, or also in driver's cab, can handle or adopt wired (wireless) distance control.The features such as electric block is a kind of extraordinary weight-lifting equipment, is installed on overhead traveling crane, gauntry crane, has volume little, from heavy and light, simple to operate, easy to use, for industrial and mining enterprises, the places such as storage harbour.Hoisting capacity is generally 0.1 ~ 80 ton, and lifting altitude is 3 ~ 30 meters.Be made up of electrical motor, transmission device and reel or sprocket wheel, be divided into steel-wire rope type electric block and Electric Chain Blocks two kinds.Electric Chain Blocks is divided into import and domestic two kinds; Steel-wire rope type electric block divides CD1 type (single speed lifting), MD1 type (double speed lifting); Minisize electric hoist, winch, multifunctional hoisting machine; Prior art generally can meet productive life needs, but spacing and control to meet the needs of people, this practicality is exactly design on this basis.
Prior art can not meet the needs of people, and for making up prior art deficiency, the present invention aims to provide a kind of electric block device.
For achieving the above object, the present invention is by the following technical solutions: a kind of electric block device, at least comprises reel assemblies, retarder, three-in-one drive system, connecting element, frame, hoisting limiter, limit switch permanent seat, screw, packing ring and hook assembly; Described reel assemblies is arranged on frame one end, and is connected with retarder; Described retarder is connected with three-in-one drive system; Described connecting element all has setting in the frame left and right sides; Described hoisting limiter is arranged on limit switch permanent seat front end, and limit switch permanent seat is fixed on frame side by screw and packing ring; Described hook assembly is connected with reel assemblies by bearing, pulley, steel rope.
As optimization technique scheme of the present invention: described three-in-one drive system to be connected with reel assemblies by retarder and described limit switch permanent seat is provided with limit switch.
Compared with prior art, the invention has the beneficial effects as follows: this electric block device, under the prerequisite that can meet lifting functions, limited location device is supposed on the basis of original hoist ceiling crane device, and the restriction of position is more accurate; Integral structure is simple, practical, is convenient to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1 ~ 4, in the embodiment of the present invention, a kind of electric block device, at least comprises reel assemblies 1, retarder 2, three-in-one drive system 3, connecting element 4, frame 5, hoisting limiter 6, limit switch permanent seat 7, screw 8, packing ring 9 and hook assembly 10; Described reel assemblies 1 is arranged on frame 5 one end, and is connected with retarder 2; Described retarder 2 is connected with three-in-one drive system 3; Described connecting element 4 all has setting in frame 5 left and right sides; Described hoisting limiter 6 is arranged on limit switch permanent seat 7 front end, and limit switch permanent seat 7 is fixed on frame 5 side by screw 8 and packing ring 9; Described hook assembly 10 is connected with reel assemblies 1 by bearing, pulley, steel rope.
As optimization technique scheme of the present invention: described three-in-one drive system 3 to be connected with reel assemblies 1 by retarder 2 and described limit switch permanent seat 7 is provided with limit switch; Described hoisting limiter 6 is connected with the limit switch wire be arranged on limit switch permanent seat 7.
Principle of work of the present invention is: three-in-one drive system is as dynamic torque mouth, dynamic torque is passed to retarder, then further cylinder is passed to, the rotation of cylinder, steel rope is wound around on cylinder, due to steel wire penetrating pulley, hook assembly is upward movement under the lifting of steel rope, and then weight gets a promotion; Limit switch plays the restriction of displacement height.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
