Abstract
The invention relates to equipment for testing an elevator safety device, in particular to a special removable wellhead cover plate device for safety component inspection equipment of an elevator. The device is provided with a derrick, particularly, a support is welded on a steel girder at one side of the wellhead of the derrick, a well lid is assembled on the wellhead of the derrick, and one side of the well lid is provided with a hinged lug hinged with the support through a hinge pin; the side wall of the derrick is provided with a lifting device, and the upper end of the lifting device is hinged with the well lid. The device can better solve the conditions that the equipment for testing the elevator safety device performs different ways of the test, the well lid can be automatically closed or started; when a worker performs ground operation, the well lid is sealed by the well cover, the well cover can be served as a working platform, and a buffer is provided for the test, and the well lid can be automatically started and a buffer channel is exposed after the equipment enters a test working state. The device is mainly used for detecting and testing the safety parts of the elevator.
Description
Technical field
The present invention relates to elevator safety parts check implement, especially a kind of elevator safety parts detect Special wellhead removable cover device.
Background technology
The special derrick of elevator safety parts check implement has two inspections function, that is: hydraulic buffer test function and progressive safety gear test functions simultaneously.
In the time doing hydraulic buffer test, need a ground surface platform with some strength as test cell, for energy disperser is installed, carry out impact test; And doing progressive safety gear when test, need to open this ground surface platform, expose the shock absorber that is placed in down-hole, to prevent rushing at the end of test rack after safety tongs test failure.Because ground surface platform is too heavy, mobile inconvenience, therefore, at present morely just in ground surface platform, put an energy disperser, buffering to test rack during for safety tongs test failure, the problem that this not only can't resolve test rack buffering is also placed in whole equipment among danger simultaneously.
Summary of the invention
Object of the present invention is exactly will solve in different elevator safety parts detect, and to the conversion of ground workplatform practical function, provides a kind of elevator safety parts to detect Special wellhead removable cover device.
Concrete scheme of the present invention is: a kind of elevator safety parts check implement Special wellhead removable cover device, there is derrick, it is characterized in that: bearing has been welded on a side girder steel of derrick well head, on derrick well head, be fitted with well lid, well lid one side is provided with hinged ear, and hinged ear and bearing adopt bearing pin hinged; On the sidewall of derrick, lifting device is installed, upper end and the well lid of lifting device are hinged.
The bottom surface of well lid described in the present invention is provided with bearing, and the upper end of this bearing and lifting device is hinged.
Lifting device described in the present invention is to adopt cylinder or oil cylinder or push-rod electric machine.
In the present invention, on well lid, have some installation screws, to facilitate, tested energy disperser is installed.
The present invention preferably resolves elevator car safety test facility, in the time carrying out multi-form test, and the problem of well lid function conversion, that is: in the time that staff carries out terrestrial operation, well lid is closed form, and well head is sealed; And enter after experimental work state when equipment, well lid can be opened automatically, exposes buffer channel; When well lid is closed, also can be as workplatform, energy disperser is installed for test.Its safety component that is mainly used in elevator detects test.
The present invention is simple in structure, have good practicality and operability, preferably resolves in the time carrying out hydraulic buffer test and progressive safety gear test the difficult problem that surface work platform practical function is changed.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention (closure state);
Fig. 2 is structure birds-eye view of the present invention;
Fig. 3 is this device opening figure.
In figure: the tested energy disperser of 1-, 2-bearing, 3-well lid, the hinged ear of 4-, 5-bearing pin, 6-bearing, 7-girder steel, 8-jack, 9-derrick, 10-shock absorber, 11-installation screw.
The specific embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3, the present invention has derrick 9, shock absorber 10 is also installed in derrick 9, particularly: bearing 6 has been welded on a side girder steel 7 of derrick 9 well heads, on derrick 9 well heads, be fitted with well lid 3, well lid 3 one sides are provided with hinged ear 4, and hinged ear 4 adopts bearing pin 5 hinged with bearing 6, on the sidewall of derrick 9, lifting device is installed, the upper end of lifting device and well lid 3 are hinged.
The bottom surface of well lid 3 described in the present embodiment is provided with bearing 2, and this bearing 2 is hinged with the upper end of lifting device.
Lifting device described in the present embodiment is to adopt jack 8(to belong to hydraulic oil cylinder driving class).Can also adopt other lifting devices such as cylinder, push-rod electric machine.
In the present embodiment, on well lid 3, have multiple installation screws 11, to facilitate, tested energy disperser is installed.
