Abstract
The utility model relates to the explosion-proof Pneumatic ring chain hoist of a kind of fixed type, comprise hook, retarder, CD-ROM drive motor, hanging assembly, pneumatic main valve, loop chain, lower suspension hook and manual pilot valve, in the left and right of hanging assembly, coaxial-symmetrical is fixedly mounted with pneumatic main valve and retarder, CD-ROM drive motor respectively, on the top of hanging assembly by axostylus axostyle hanging suspension hook seat, suspension hook seat is hung oneself and is loaded onto suspension hook, the endless chain sprocket of retarder drives the loop chain of hanging assembly to move, the lower end of loop chain mounts suspension hook seat, the lower suspension hook of this suspension hook seat lower end lifting; Pneumatic main valve connects main tracheae respectively and controls tracheae, and main tracheae is communicated with pneumatic main valve, controls tracheae and is communicated with manual pilot valve.This ring-chain hoist adopts the mid-mode of hanging, and motor and retarder respectively both sides are arranged, avoid the skew in lifting process and rotation, volume is little, lightweight, stable and reliable operation, is the most small-sized weight-lifting equipment layout type of failure-free.
Description
Technical field
The utility model belongs to elevator machinery field, the explosion-proof Pneumatic ring chain hoist of especially a kind of fixed type.
Background technology
In lifting field, hand-driven ring-chain hoist structure is simple, and easy to operate, shortcoming is that hoisting capacity is little, and efficiency is low, is mainly used in lifting occasion more among a small circle.Air hoist exploitation is more late, is to adopt air motor as power, and structure is simple, and with low cost, explosion-proof effect is good, and shortcoming is that hoisting capacity is little, and needs source of the gas.For air hoist, the major cause that hoisting capacity is little is because integral structure is unreasonable, configuration overbalance, the configuration of retarder, transmission configuration, drive arrangements existing problems.
By retrieval, find one section of patent documentation (title: synchronously drive pneumatic endless chain hoister, patent No.: 02233824.1) relevant to air hoist.By analyzing, the reformed AHP point of the disclosure patent is that needs two air hoists synchronously lift, and still has the lifting of existing air hoist and less, that field of application the is less shortcoming that hoists.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and has explosion-proof performance and little, lightweight, the reliable explosion-proof Pneumatic ring chain hoist of fixed type of volume.
The purpose of this utility model is achieved in that
The explosion-proof Pneumatic ring chain hoist of a kind of fixed type, comprise hook, retarder, CD-ROM drive motor, hanging assembly, pneumatic main valve, loop chain, lower suspension hook and manual pilot valve, in the left and right of hanging assembly, coaxial-symmetrical is fixedly mounted with pneumatic main valve and retarder, CD-ROM drive motor respectively, on the top of hanging assembly by axostylus axostyle hanging suspension hook seat, suspension hook seat is hung oneself and is loaded onto suspension hook, the endless chain sprocket of retarder drives the loop chain of hanging assembly to move, and the lower end of loop chain mounts suspension hook seat, the lower suspension hook of this suspension hook seat lower end lifting; Pneumatic main valve connects main tracheae respectively and controls tracheae, and main tracheae is communicated with pneumatic main valve, controls tracheae and is communicated with manual pilot valve.
And described loop chain adopts dual loop chain structure.
Advantage of the present utility model and good effect are:
1, this ring-chain hoist adopts the mid-mode of hanging, and motor and retarder respectively both sides are arranged, avoid the skew in lifting process and rotation, volume is little, lightweight, stable and reliable operation, is the most small-sized weight-lifting equipment layout type of failure-free.
2, the built-in drg of this ring-chain hoist air motor, can ensure that drg is completely closed, meet highest ranking requirement of explosion proof; Totally-enclosed planetary reduction gear, meets the requirement of explosion proof of highest ranking.
3, this ring-chain hoist is set up suspension hook, bottom symmetry installs loop chain suspension hook, integral structure is simple, design science is reasonable, solve existing Pneumatic ring chain hoist Problems existing, effectively improve the hoisting capacity of Pneumatic ring chain hoist, field of application is wide, is particularly useful for the lifting of the explosion-proof occasions such as oil, chemical industry, mine.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; It should be noted that: the present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The explosion-proof Pneumatic ring chain hoist of a kind of fixed type, comprise hook 1, retarder 5, CD-ROM drive motor 6, hanging assembly 4, pneumatic main valve 12, loop chain 7, lower suspension hook 9 and manual pilot valve 10, in the left and right of hanging assembly, coaxial-symmetrical is fixedly mounted with pneumatic main valve and retarder, CD-ROM drive motor respectively, suspension hook seat 2 is hung by axostylus axostyle 3 on the top of hanging assembly, suspension hook seat is hung oneself and is loaded onto suspension hook, and this hook is for being fixedly lifted on building; Endless chain sprocket in hanging assembly links with the output shaft of retarder, and this retarder is totally-enclosed planetary reduction gear, to meet the requirement of explosion proof of highest ranking; The endless chain sprocket of retarder drives loop chain to move, and the lower end of loop chain mounts suspension hook seat 8, the lower suspension hook of this suspension hook seat lower end lifting.There is air motor, the built-in drg of this air motor in the pneumatic main valve that hanging assembly is fixedly mounted with, can ensure that drg is completely closed, meet highest ranking requirement of explosion proof.
Pneumatic main valve connects main tracheae 13 respectively and controls tracheae 11, and main tracheae is communicated with pneumatic main valve, controls tracheae and is communicated with manual pilot valve.
Described air motor adopts pneumatic vane motor, and loop chain adopts dual loop chain structure, drive motor retarder, and the output shaft of retarder drives endless chain sprocket to rotate, thus the displacement of engagement loop chain, realize lifting.
Claims (2)
