Technical field

The invention belongs to crane production technical fields, more particularly to a kind of lifting device offset monkey.

Background technique

Crane refers to more movement hoisting machineries of vertical-lift in a certain range and horizontal carrying heavy goods, rises between reforming The movement of having a rest property, i.e., the corresponding mechanism of the movements such as feeding, migration, unloading is to work alternatively in a working cycles, crane Develop in the market and using more and more extensive.Monkey is the important composition component of crane, is mainly used for material Promotion and movement, and existing monkey mostly be arranged in crane girder lower end track on walking (such as Fig. 1 institute Show), crane girder can all limit the hoisting depth of trolley, cannot adequately utilize the room for promotion of monkey, especially It is the region for short workshop or operating space, will limit the hoisting depth of material significantly.

Summary of the invention

The purpose of the invention is to provide a kind of lifting device offset monkey, solves and rise in the prior art The restricted problem of heavy-duty machine trolley hoisting depth.

The present invention is adopted the technical scheme that solve the above-mentioned problems, provides a kind of lifting device offset lifting Machine trolley, including motor reducer all-in-one machine, pulley, suspension hook, electric block further include door shape frame, door shape frame Opening straddles the top of crane girder, is rotatably connected to travelling wheel, fixing sleeve on the wheel shaft of travelling wheel on door shape frame Equipped with passive transmitting gear, motor reducer all-in-one machine is fixedly connected with door shape frame, the power of motor reducer all-in-one machine Output shaft pass through door shape frame, and the end fixing sleeve of power output shaft be equipped with active transmission gear, active transmission gear with Passive transmitting gear is meshed, and mounting plate is fixedly connected on door shape frame, and mounting plate is fixedly connected with electric block, electronic Wirerope one end rope end of cucurbit is fixedly connected with electric block, and wirerope bypasses cunning after winding a few on electric block It takes turns and other end rope end is fixedly connected with door shape frame.

Supporting roller component is fixedly connected on the inside of the door shape frame.

The supporting roller component includes symmetrically arranged two pieces of L shape support plate, is rotatably connected between two pieces of L shape support plates Axis, fixing sleeve is equipped with scroll wheel in shaft.

The scroll wheel is coated with nylon gelatinous coating along its circumferential surface.

The position of the supporting roller component of the close electric block is higher than the position of the supporting roller component far from electric block.

Beneficial effects of the present invention: the structure of the invention is simple, will be lifted by crane by electric block using suspension hook when use Material lifting, due to the trolley relative to crane girder bias be arranged, the hoisting depth of material with it is existing Trolley hoisting depth is compared, and will significantly be improved, its promotion is high compared with the existing for the monkey of the patent of invention Degree increases 80~90cm, makes the hoisting depth of material as far as possible close to the girder of crane, has thus considerably increased The scope of application of heavy-duty machine, in particular for using in the environment of short workshop or operating space, furthermore the monkey is inclined Set the maintenance and repair that setting structure is more advantageous to monkey.

Specific embodiment

To keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention is implemented with reference to the accompanying drawing Mode is described in further detail.

As shown in Figure 2 and Figure 3, the present invention provides a kind of lifting device offset monkeies, including motor reducer All-in-one machine 1, pulley 2, suspension hook 3, electric block 4, further include door shape frame 5, and the opening of door shape frame 5 straddles crane The top of girder 6, the lower end of crane girder 6 is with a narrow upper and lower width trapezoidal in the embodiment, can effectively avoid wirerope Crane girder 6 is scratched in the process of ascension.Travelling wheel 7 is rotatably connected on door shape frame 5, on the wheel shaft of travelling wheel 7 Fixing sleeve is equipped with passive transmitting gear 8, and motor reducer all-in-one machine 1 is fixedly connected with door shape frame 5, motor reducer one The power output shaft of machine 1 passes through door shape frame 5, and the end fixing sleeve of power output shaft is equipped with active transmission gear 9, actively Transmission gear 9 is meshed with passive transmitting gear 8, is fixedly connected with mounting plate 10 on door shape frame 5, mounting plate 10 with it is electronic Cucurbit 4 is fixedly connected, and 11 one end rope end of wirerope of electric block 4 is fixedly connected with electric block 4, and wirerope 11 is electronic It is wound on cucurbit 4 and bypasses pulley 2 after a few and other end rope end is fixedly connected with door shape frame 5.

The inside of the door shape frame 5 is fixedly connected with supporting roller component 12, and supporting roller component 12 can ensure that crane is small The stability of vehicle traveling and the stability of promotion.As shown in figure 4, supporting roller component 12 includes symmetrically arranged two pieces of L shape support plate 1201, shaft 1202 is rotatably connected between two pieces of L shape support plates 1201, fixing sleeve is equipped with scroll wheel 1203 in shaft 1202, Scroll wheel 1203 is coated with nylon gelatinous coating 1204 along its circumferential surface, in this way when scroll wheel 1203 is moved along crane girder 6 Crane girder 6 can be effectively avoided to be scratched, the position close to the supporting roller component 12 of electric block 4 is higher than far from electronic calabash The position of the supporting roller component 12 of reed 4.

In use, the walking rails 13, In matched with travelling wheel 7 are arranged on the outside of the top surface of 6 spar-box of crane girder The Auxiliary Track 14 that setting is matched with scroll wheel 1203 on the outside of the spar-box side of crane girder 6, and rise in this embodiment The inside top surface of 6 spar-box of heavy-duty machine girder is fixedly connected with angle bar 15, and for improving the spar-box intensity of crane girder 6, forward direction is driven Dynamic motor reducer all-in-one machine 1, makes monkey be moved to the top of material to be lifted, forward driving along walking rails 13 Electric block 4 declines suspension hook 3 and hooks material, is driven in the reverse direction electric block 4, increase suspension hook 3, drives material lifting, instead To driving motor speed reducer all-in-one machine 1, material is moved in the region to discharging.The structure of the invention is simple, since this rises Weight trolley is biased relative to crane girder 6 to be arranged, therefore the hoisting depth of material and existing trolley hoisting depth phase Than will significantly improve, and make the hoisting depth of material as far as possible close to the girder of crane, thus considerably increase lifting The scope of application of machine, in particular for being used in the environment of short workshop or operating space.

The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this The principle of invention, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these changes Change and improvement is both fallen within the scope of claimed invention.
