Abstract
The utility model discloses an internally piloting auto -lock ladder head, including hanging hole base (1) and hanging hole (5), link to each other through length adjustable rod spare between hanging hole base (1), link to each other through chain (2) between hanging hole (5). The utility model discloses pole setting interval adjusting device has prevented to come the potential safety hazard because of the deformation band that load led to the fact about having increased on original ladder first basis, and the cable who increases on the hanging hole is then have one protection for the safety hook has increased.
Description
Technical field
This utility model relates to the hanging hole on a kind of internal control type self-locking ladder head, particularly ladder head vertical rod.
Background technology
Utility model patent (Authorization Notice No.: the CN204905756U of entitled " a kind of internal control type self-locking ladder head ", authorized announcement date: 2015.12.23) disclose the terraced head used in a kind of livewire work, this ladder head is capable of the automatic shutter of opening part (i.e. below pulley cable be linked into position), has fully ensured the safety of operating personnel.
It is each provided with a coaster hanging hole in the left and right vertical rod of above-mentioned ladder head, is used for hanging coaster or personal safety protector (such as catching device).During actually used, owing to two coaster hanging holes are positioned at the free end of left and right vertical rod, vertical rod simultaneously uses hollow aluminum matter pipe to alleviate weight, has relatively noticeable effort can cause vertical rod bending when pulling hanging hole when for a long time, thus causes the hitch point of catching device to bury potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is: provides a kind of internal control self-locking ladder head, increases the non-deformability of left and right vertical rod, solves the issuable potential safety hazard of hanging hole further.
The technical solution adopted in the utility model is: a kind of internal control self-locking ladder head, including hanging hole base and hanging hole, is connected by adjustable length rod member between hanging hole base, is connected by chain between hanging hole.The addition of adjustable length rod member, it is ensured that the spacing between left and right vertical rod hanging hole base is the most adjustable, reduces diastrophic impact.And between hanging hole, use chain to connect, then add a pipe protection, be i.e. tied to the hanging hole of opposite side by chain.
Described adjustable length rod member includes left and right two sections of screw rods, and one end of two sections of screw rods is connected with hanging hole base, and the other end is connected by screw shell.Two sections of screw rods are connected with hanging hole base by screw thread, be connected with sleeve end due to thread rotary orientation contrary, turnbarrel can realize two sections of screw rods close or away from.
This utility model adds left and right vertical pole's span adjusting apparatus on the basis of original ladder head, it is therefore prevented that the deformation caused because of load brings potential safety hazard, and the connection chain that hanging hole increases then has added a pipe protection for catching device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the overall structure schematic diagram of internal control self-locking ladder head.
Detailed description of the invention
Below in conjunction with Figure of description, the technical solution of the utility model is further illustrated:
As shown in Fig. 1～2, a kind of internal control self-locking ladder head, including a pair hanging hole base 1 and a pair hanging hole 5, hanging hole base 1 is fixed in ladder head left and right vertical rod.Between hanging hole base 1, logical left and right two sections of screw rods 3 and screw shell 4 are connected, and one end of two sections of screw rods 3 is connected with hanging hole base 1, and the other end is connected by screw shell 4.Two sections of screw rods 3 are connected with hanging hole base 1 by screw thread, be connected with sleeve 4 end due to thread rotary orientation contrary, turnbarrel can realize two sections of screw rods close or away from.It is connected by chain 2 between hanging hole 5.The type of attachment of left and right two sections of screw rods 3 and screw shell 4 ensure that the spacing between the hanging hole base 1 of left and right vertical rod is the most adjustable, decreases diastrophic impact.Use chain 2 to connect between hanging hole 5, then add a pipe protection, be i.e. tied to the hanging hole 5 of opposite side by chain 2.
Claims (2)
1. an internal control self-locking ladder head, including hanging hole base (1) and hanging hole (5), it is characterized in that: be connected by adjustable length rod member between hanging hole base (1), be connected by chain (2) between hanging hole (5).
A kind of internal control self-locking ladder head the most according to claim 1, it is characterized in that: described adjustable length rod member includes left and right two sections of screw rods (3), one end of two sections of screw rods (3) is connected with hanging hole base (1), and the other end is connected by screw shell (4).
