Abstract
The utility model discloses an anti-falling safety device, which comprises a braking part and a driving centrifugal speed limiting part, wherein a bearing is arranged in an end cover hole formed in the driving centrifugal speed limiting part. The anti-falling safety device is characterized in that the bearing is an embedded solid lubrication bearing. Through the adoption of the technical scheme, the anti-falling safety device has the advantages that an oil-free self-lubricating sliding bearing in the traditional driving centrifugal speed limiting part and the braking part in the market is changed into the embedded solid lubrication bearing with high bearing capability, impact resistance, high temperature resistance, high self-lubricating capability and wear resistance, the service life of the bearing is prolonged, the noise generated in the operation process of the safety device because of the traditional oil-free bearing abrasion is reduced, meanwhile, because the maintenance period of the safety device is prolonged, the depot repair cost of the safety device is greatly reduced, the maintenance cost is reduced, the safety of products is improved, and in addition, the structure design is simple and convenient.
Description
Technical field
The utility model relates to a kind of anti-falling safety device, refers in particular to a kind of building hoist gear cone cydariform gradual anti-falling safety device.
Background technology
Anti-falling safety device is mounted in the fall-preventing protection device on the building hoist; existing anti-falling safety device is mainly gear cone cydariform gradual anti-falling safety device, and its inner oilless metal load-carrying capacity of adorning is lower, and service life is not long; be easy to generate noise after the wearing and tearing, cause the after-sales service cost higher.Gear cone cydariform gradual anti-falling safety device keystone configuration is brake portion and drives centrifugal speed limit two large divisions's composition; because need add lead sealing after safety dispatches from the factory just can be delivered for use; the user can not take the lead sealing of safety apart and refuel; the oil-less self-lubricating bearing that causes brake portion lubricates and is difficult to put in place; wearing and tearing easily; and the oil-less self-lubricating bearing that drives under the centrifugal speed limit position (is equipped with alemite at safety gear wheel shaft end face; stipulating to inject for 2 times every month butter is lubricated); because load-carrying capacity is lower; situation or safety in building hoist heavy duty and drop test are installed under the undesirable situation; be easy to wear and tear; cause becoming greatly with the diameter clearance of oilless metal endoporus with axle; after this two oilless metaies wearing and tearing axis hole gap becomes greatly; be easy to generate noise in operational process, the safety of moving to building hoist causes a hidden trouble, and will frequently change accessory; certainly will cause maintenance cost and increase equipment downtime, bring influence for the safe operation of elevator.
Summary of the invention
Not long service life at existing anti-falling safety device oilless metal, problem such as load-carrying capacity is lower, wear resisting property is low, the purpose of this utility model is to provide a kind of load-carrying capacity height, shock-resistant, and is high temperature resistant, the anti-falling safety device that the self-lubricating ability is strong and wear-resisting.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of anti-falling safety device, comprise brake portion and drive centrifugal speed limit part, in the ending cover hole in the centrifugal speed limit part of described driving a bearing is housed, it is characterized in that: described bearing is inserted bearing with solid lubricant.
Further, described brake portion comprises a braking hub, press-fits inserted bearing with solid lubricant in the described braking hub.
Further, described anti-falling safety device is gear cone cydariform gradual anti-falling safety device.
Adopt technique scheme, anti-falling safety device described in the utility model, oil-free self lubrication plain bearing in the centrifugal speed limit part of traditional on the market driving and the brake portion is improved to the load-carrying capacity height, shock-resistant, high temperature resistant, the inserted bearing with solid lubricant that the self-lubricating ability is strong and wear-resisting, prolonged the service life of bearing, reduced because of the wearing and tearing of traditional oilless metal and caused the noise that produces in the safety operational process, simultaneously because the prolongation of the maintenance cycle of safety, significantly reduce the expense of safety depot repair, reduced maintenance cost, improved security of products, and structure design is simple, and is convenient.
Description of drawings
Fig. 1 is anti-falling safety device assembly drawing described in the utility model;
Fig. 2 is the centrifugal speed limit part of driving scheme drawing shown in Figure 1;
Wherein: 1. drive centrifugal speed limit part, 2. braking shell friction pair, 3. second bearing, 4. braking hub, 5. disk spring group, 6. swivel nut, 7. block, 8. joint shaft gear, 9. clutch shaft bearing, 10. spline pin, 11. oil sealings, 12. end caps.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As Figure 1-3, a kind of anti-falling safety device, comprise brake portion and drive centrifugal speed limit part 1, brake portion is mainly by loading onto braking hub 4 in the braking shell friction pair 2, brake second bearing 3 of packing in the hub 4, braking hub 4 passes through dish spring group 5 and block 7 with braking shell friction pair 2, swivel nut 6 connections compress, make the stressed conical surface that will brake hub 4 and braking shell friction pair 2 of dish spring strain, drive centrifugal speed limit part 1 mainly by joint shaft gear 8, by outside framework oil seal 11, clutch shaft bearing 9 is packed in the end cap 12, make axial limiting by spline pin 10, at the tail end of joint shaft gear 8, be pressed into centrifugal speed-limit device, to drive centrifugal speed limit part at last and attach together by two socket bolts with brake portion, in addition lead sealing is namely to finish the assembling of whole product.In the utility model, clutch shaft bearing 9 and second bearing 3 are inserted bearing with solid lubricant.
The principle of work of anti-falling safety device described in the utility model is: anti-falling safety device is fixed in the building hoist on the installation platelet in the cage by the 4-mounting hole, make safety gear and elevator rack mesh, safety drives centrifugal device and makes gyroscopic movement along with elevator craning cage moves up and down by specified hoisting speed, when elevator breaks down, when cage stall tenesmus reaches the responsiveness of safety demarcation, throw away for centrifugal in the centrifugal speed-limit device and drive the rotation of braking hub, and then swivel nut makes lock torque increase gradually by compact disc spring group, in certain stopping distance with the steady stop of its cage on guide rail bracket, guarantee that passenger's life security and equipment is not damaged.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; in not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
