Abstract
The invention relates to a retaining device, in particular to a retaining device for retaining a hanger trolley, and belongs to the technical field of mechanical equipment. The retaining device comprises a mounting support; a base is fixed on the mounting support; a rotating shaft is rotatably mounted in the base; a release handle in an L shape is welded at the left end of the rotating shaft; a retaining arm is connected to the right end of the rotating shaft; a return spring is arranged between the release handle and the base. The retaining device is simple, compact and reasonable in structure, convenient and reliable to use and low in cost; the retaining device can prevent the hanger trolley from running out of a rail in case of switch failure, and safety is guaranteed.
Description
Technical field
The present invention relates to a kind of retaining means, a kind of hoisting tool bogie retaining means, belongs to mechanical equipment technical field specifically.
Background technology
In prior art, may there is malfunctioning switch phenomenon in the elevator that is welded in lifting process, and the suspender be parked in after malfunctioning switch in movable rail easily plunges off the tracks, and causes safety misadventure.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of hoisting tool bogie retaining means is provided, can stop that hoisting tool bogie plunges off the tracks when malfunctioning switch, ensure that safety.
According to technical scheme provided by the invention, hoisting tool bogie retaining means comprises mounting bracket, it is characterized in that: permanent seat on mounting bracket, rotates and install rotating shaft in pedestal; Rotating shaft left end welding L shape open handle, rotating shaft right-hand member connects blocking arm; Open between handle and pedestal and be provided with pull back spring.
Further, open on handle and be set with roller.
Further, rotating shaft is provided with self-lubricating bearing with pedestal junction.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, easy to use and reliable, and cost is lower; Can stop that hoisting tool bogie plunges off the tracks when malfunctioning switch, ensure that safety.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is lateral plan of the present invention.
Description of reference numerals: 1-mounting bracket, 2-pedestal, 3-open handle, 4-rotating shaft, 5-blocking arm, 6-self-lubricating bearing, 7-pull back spring, 8-roller.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention mainly comprises mounting bracket 1, and mounting bracket 1 is bolted in movable rail exit.
Permanent seat 2 on mounting bracket 1, rotates in pedestal 2 and installs rotating shaft 4.Rotating shaft 4 left end welding L shape open handle 3, rotating shaft 4 right-hand member connects the blocking arm 5 blocking movable rail outlet.
Described opening on handle 3 is set with roller 8.
Described opening between handle 3 and pedestal 2 is provided with pull back spring 7, and pull back spring 7 can be opened handle 3 by spring tension drive and get back to original position.
Described rotating shaft 4 is provided with self-lubricating bearing 6 with pedestal 2 junction, is reduced the friction of rotating shaft 4 rotation by self-lubricating bearing 6.
Principle of work of the present invention is: the present invention is arranged on movable rail exit, and at ordinary times, when after malfunctioning switch, due to the stop of blocking arm, hoisting tool bogie cannot go out movable rail.When normally running, after track rising puts in place, the roller opening handle is stirred on the inclined-plane being arranged on the device for opening on trapped orbit, makes blocking arm rotate clockwise an angle, leaves movable rail, thus realize passing through smoothly of hoisting tool bogie.
Structure of the present invention is simple, compact, reasonable, easy to use and reliable, and cost is lower; Can stop that hoisting tool bogie plunges off the tracks when malfunctioning switch, ensure that safety.
