Abstract
The utility model discloses a kind of anti-fall sleeve suitable for hanging bolt Fast Installation, including the sleeve of anti-skidding pin and socket bolt head, one end socket bolt head of sleeve, the other end are provided with two pin-and-holes for installing anti-skidding pin；The sleeve is in hollow cylinder shape, and the cross section of sleeve lining is in the shape matched with bolt head；Height of the height of the sleeve more than bolt head；This utility model simple structure, it is not necessary to change original derrick geometry, it is only necessary to set up sleeve and relative pin part；By anti-fall sleeve weld on capillary tube derrick, effectively deduction and exemption standing stands in lower end auxiliary fastening bolt, only need in upper brace pair seam, hexagonal screw thread is preset in anti-fall sleeve, anti-fall pin is added after only needing to insert bolt, one people can complete derrick linking above upper brace and install, the effective falling from high altitude for preventing operator to cause because of operational error etc., object strike accident.
Description
Technical field
This utility model is related to the installation tool of derrick, specifically a kind of anti-fall set suitable for hanging bolt Fast Installation
Cylinder.
Background technology
For derrick geometry, the safety problem to staff, it is proposed that some anti-fall structures are improved.For example, it is open
Day for August in 2000 23 days, the Chinese utility model patent document of Publication No. CN2392749 discloses derrick and portal frame
Lift cage is arbitrarily stopped, anti-fall device, and which includes：Perpendicular guide rail clamp system, the lifting movable pulley mechanism of drawing sensing rope,
With the operating mechanism for adjusting sensing rope level of tightness.The operating mechanism passes through planar linkage mechanism and spatial linkage, realizes
Hanging basket goes up the effect of safety stop and anti-fall automatic protection at an arbitrary position.Again for example, publication date is August in 2000 23, public
The number of opening is the Chinese utility model patent document of CN2103540, discloses a kind of anti-drop apparatus of hoister, and the device has disconnected
Rope protection and two kinds of functions of door-opening self-locking.A pair of steps are consolidated every a segment distance on a pair of corner posts of derrick.Traction steel wire
Rope is connected with hanging scaffold by wedge.Wedge is placed in two ends with steel tongue in the middle part of the cross-arm being flexibly connected.The buffered device of cross-arm with hang
Cage on disk is connected.The flexible of steel tongue is controlled by the push rod being placed between wedge and steel tongue and anti-fall purpose is reached.Together
When, it is provided with cage and can be opened and closed and mobile lead wheel with feeding door, is connected with steel tongue by self-locking steel wire and realizes opening the door
Auto-lock function.Anti-fall dependable performance, can be widely used on the elevator of old derrick geometry.
But capillary tube derrick dispatches from the factory during design, the height of derrick is generally higher than 2 meters.During derrick installation, due to
Space and structure constraint, each derrick joining place are connected by single ended bolt, need a people to assist anchor stud head in lower end, but in peace
Due to, the during bolt installation meeting not convenient without the fastening of space bolt without operator's standing space, lower end spanner below derrick during dress
Jing often drops, and there is the accidents such as operator's eminence slides, bolt falling object from high altitude causes object to hit.
Utility model content
This utility model is to overcome above-mentioned technological deficiency, there is provided a kind of anti-fall set suitable for hanging bolt Fast Installation
Cylinder, the bolt that effectively can be fixedly connected prevent from loosening, so as to solve the dangerous feelings under staff is fallen because of bolt looseness
Condition.
The technical solution of the utility model is as follows：
A kind of anti-fall sleeve suitable for hanging bolt Fast Installation, it is characterised in that：Including anti-skidding pin and socket spiral shell
The sleeve of bolt head, one end socket bolt head of sleeve, the other end are provided with two pin-and-holes for installing anti-skidding pin；The sleeve is in
Hollow cylinder shape, the cross section of sleeve lining is in the shape matched with bolt head；The height of the sleeve is more than bolt head
Highly.
The tapering point of the anti-skidding pin is provided with through hole, for installing retraction pin.
Installation process of the present utility model is：
One end of the sleeve is welded in the joint of capillary tube operation pedestal lower end and screw, and bolt is faced upwards from down
Screw after insertion sleeve through derrick interface is locked with nut, then by anti-skidding pin through two on anti-fall sleeve
Individual pin-and-hole is fixed, then prevents anti-skidding pin from coming off on the through hole that retraction pin insertion anti-skid stud is nailed on, and is hindered by anti-skidding pin
Gear bolt head loosens and drops, and plays fixation.
The beneficial effects of the utility model are as follows：
1. this utility model simple structure, it is not necessary to change original derrick geometry, it is only necessary to set up sleeve and respective pins
Nail part；
2. bolt head and form fit in sleeve, can prevent bolt head from rotating and come off, then coordinate anti-skidding pin further
It is fixed；
3., by anti-fall sleeve weld on capillary tube derrick, effectively deduction and exemption standing stands in lower end auxiliary fastening spiral shell
Bolt, it is only necessary to the seam in upper brace pair, presets hexagonal screw thread, it is only necessary to anti-fall pin is added after inserting bolt in anti-fall sleeve
Nail, a people can complete derrick linking above upper brace and install, and effectively prevention operator are made because of operational error etc.
Into falling from high altitude, object strike accident, improve operational security.

Specific embodiment
As shown in figure 1, a kind of anti-fall sleeve suitable for hanging bolt Fast Installation, including anti-skidding pin 4 and socket spiral shell
The sleeve 3 of bolt head 1, one end socket bolt head 1 of sleeve 3, the other end are provided with two pin-and-holes 5 for installing anti-skidding pin 4.
As in Figure 2-4, the sleeve 2 is in hollow cylinder shape, and the cross section of 2 inwall of sleeve is in matching with bolt head 1
Shape, generally regular hexagon；Height of the height of the sleeve 2 more than bolt head 1.
The tapering point of the anti-skidding pin 4 is provided with through hole 6, for installing retraction pin.
Installation process of the present utility model is：
One end of the sleeve 2 is welded in the joint of capillary tube operation pedestal lower end and screw, by bolt under towards
Screw after upper insertion sleeve 2 through derrick interface 7 is locked with nut 2, and anti-skidding pin 4 is passed through anti-fall sleeve then
Two pin-and-holes 5 on 2 are fixed, then retraction pin are inserted prevent anti-skidding pin 4 from coming off on the through hole 6 on anti-skidding pin 4, are passed through
Anti-skidding pin 4 stops that the loosening of bolt head 1 is dropped, and plays fixation.
