Abstract
The utility model discloses a linkage mechanism for elevator safety tongs. The linkage mechanism comprises a connection rod and a speed limiter rope connection rod installed on the end portion of the connection rod. The connection rod is provided with two lifting and resetting mechanisms. Each lifting and resetting mechanism is provided with a fixing support matched with the connection rod in a rotating mode, a safety tongs lifting rod fixed to the connection rod, and a resetting spring installed on the connection rod in a sleeved mode, wherein the two ends of the resetting spring are connected with the fixing support and the safety tongs lifting rod respectively. The linkage mechanism has the advantages of being simple in structure, convenient to install, small in occupied installation space, and capable of meeting the use requirements for an elevator from small space.
Description
Technical field
The utility model relates to a kind of link gear of elevator safety gear, belongs to lift facility technical field.
Background technology
Elevator safety clamp device is under the manipulation of velocity limiter, when elevator occurs after the very serious fault such as hypervelocity, disconnected rope, by urgent car stop and be clamped in a kind of safety device on guide rail.It provides actv. protective effect to the safe operation of elevator, is generally arranged on car frame or counterweight frame.
The action of safety tongs device is: moved and made rope-clamping pliers clamp governor rope by velocity limiter, along with the downward operation of car, governor rope is mentioned safety tongs link gear, cause the action of safety tongs link gear, by shift mechanism pull-up lifting rod, impel voussoir upward sliding in its clamp block of safety tongs, after contacting with guide rail, voussoir produces rubbing effect, drive safety tongs braking element to contact with guide rail, safety tongs is clamped on guide rail, stop car simultaneously.
But not only complex structure of the link gear of existing safety tongs (as depicted in figs. 1 and 2), and requirements of installation space is larger, is not suitable for installing and using of some less occasion in space, thus make the application of elevator be subject to certain limitation.
Summary of the invention
The problems referred to above that exist for prior art, the utility model aim to provide a kind of simple in structure, the link gear of little elevator safety gear of taking up room is installed, elevator operating needs that can the less occasion of meeting spatial.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of link gear of elevator safety gear, comprise: pipe link, be installed on the governor rope connecting rod of pipe link end, two covers are housed on described pipe link and lift Bringing-back mechanism, described in lift Bringing-back mechanism and have and be connected with fixed support and safety tongs lifting rod respectively with the fixed support of pipe link normal-running fit, the safety tongs lifting rod fixing with pipe link and two ends and be sleeved on the reduction torsion spring on pipe link.
The utility model also has following further improvement:
1, the first end of described governor rope connecting rod is fixedly connected with pipe link end, and the second end of governor rope connecting rod is connected with speed limiter wire rope.
2, between described fixed support and pipe link, rolling bearing is housed.
3, two described covers lift Bringing-back mechanism and are arranged on pipe link with symmetric form.
The utility model is by being connected in governor rope connecting rod, two safety tongs lifting rods and two fixed supports on pipe link, in the time that velocity limiter moves, governor rope drives governor rope connecting rod up to carry, now because of support bracket fastened position-limiting action, pipe link can only rotate, and triggers safety tongs action thereby then drive two safety tongs lifting rods up to carry.
Compared with prior art, the utlity model has simple in structurely, easy for installation, install and take up room littlely, can be applicable to the elevator operating needs of the less occasion in space.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the link gear of elevator safety gear of the prior art;
Fig. 2 is the working state figure of the link gear of elevator safety gear of the prior art;
Fig. 3 is the schematic diagram of the link gear of a kind of elevator safety gear of providing of the utility model.
Fig. 4 is the right elevation of Fig. 3.
Number in the figure is schematically as follows: 1-pipe link, and 2-governor rope connecting rod, 3-lifts Bringing-back mechanism, 31-fixed support, 32-reduction torsion spring, 33-safety tongs lifting rod.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the technical solution of the utility model is clearly and completely described.
As shown in Figure 3 and Figure 4: the link gear of a kind of elevator safety gear that the utility model provides, comprise: pipe link 1, be installed on the governor rope connecting rod 2 of pipe link 1 end, two covers are housed on pipe link 1 and lift Bringing-back mechanism 3, lift Bringing-back mechanism 3 and have and be connected with fixed support 31 and safety tongs lifting rod 33 respectively with the fixed support 31 of pipe link 1 normal-running fit, the safety tongs lifting rod 33 fixing with pipe link 1 and two ends and be sleeved on the reduction torsion spring 32 on pipe link 1.The first end of governor rope connecting rod 2 is fixedly connected with the end of pipe link 1, and second end (in Fig. 4, the one end that pulled by velocity limiter lineoutofservice signal pull F) of governor rope connecting rod 2 is connected with speed limiter wire rope.Two covers lift Bringing-back mechanism 3 and are arranged on pipe link 1 with symmetric form.
In order to reduce the rotary resistance between fixed support 31 and pipe link 1, between fixed support 31 and pipe link 1, rolling bearing (not shown) is preferably housed.
The utility model is by being connected in governor rope connecting rod 2, two fixed supports 31 and two safety tongs lifting rods 33 on pipe link 1, in the time that velocity limiter moves, governor rope drives governor rope connecting rod 2 up to carry, now because of the position-limiting action of fixed support 31, pipe link 1 can only rotate, thereby thereby driving two safety tongs lifting rods 33 up to carry triggers safety tongs action.
Compared with prior art, the utlity model has simple in structurely, easy for installation, install and take up room littlely, can be applicable to the elevator operating needs of the less occasion in space.
Finally be necessary described herein: foregoing is only for being described in further detail the technical solution of the utility model; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
