Description
Technical field
It the utility model is related to a kind of fall arrest brake structure of lift.
Background technology
Hydraulic companion ladder is the cargo lift for transporting cargo between the different floors of building；Generally by hydraulic link
Bar system drive, can set operation button on each floor and lifting platform, realize multiparty control, have firm in structure, carrying
Amount is big, lifting is steady, installation is safeguarded the features such as simple and convenient, economic and practical, is used in lowrise interlayer to substitute elevator
Preferable cargo conveying equipment；In order to improve security, lift generally requires the protection mechanism for setting fall arrest, and existing guarantor
It is mostly complex to protect mechanism, installation cost is high, but practicality is low.
Utility model content
For above-mentioned technical problem, the purpose of this utility model is：The fall arrest for proposing a kind of lift is stopped
Bassinet structure.
What the technical solution of the utility model was realized in：A kind of fall arrest brake structure, comprising leading truck and
Lifting platform, is provided with vertical guide rail, rack and brake rib on leading truck, and the guide rail of lifting platform and leading truck is slidably matched；Institute
State the detection components and locking member for being provided with lifting platform and coordinating with rack, and the brake assemblies coordinated with brake rib；Institute
State detection components and include velocity sensor, the gear coordinated with rack is provided with velocity sensor；The locking member includes
Locked cylinder, the cylinder rod end set of locked cylinder have the locking teeth coordinated with rack；The brake assemblies are set comprising two
The brake oil cylinder in brake rib both sides is put, the cylinder rod end set of brake oil cylinder has the brake block coordinated with brake rib.
Preferably, the velocity sensor is arranged on the table top of lifting platform.
Preferably, the locked cylinder and brake oil cylinder are arranged at the downside of lifting platform.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
The fall arrest brake structure of the utility model, sets rack and brake rib on leading truck, and is set on lifting platform
Detection components, locking member and brake assemblies are put to improve security；Detection components are used for anxious fall and detect, by brake assemblies into
Row brake, brake is locked after stopping by locking member, simple and reliable for structure.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of schematic diagram of fall arrest brake structure described in the utility model.
Embodiment
Illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of fall arrest brake structure described in the utility model, comprising leading truck 1 and lifting platform 4, leads
A plurality of vertical guide, rack 11 and brake rib 12 are provided with to frame 1, lifting platform 4 and the guide rail of leading truck 1 are slidably matched；Institute
State the detection components and locking member for being additionally provided with lifting platform 4 and coordinating with rack 11, and the brake coordinated with brake rib 12
Component；The detection components include velocity sensor 13, and velocity sensor 13 is located on the table top of lifting platform 4, velocity sensor
The gear 14 coordinated with rack 11 is provided with 13；The locking member includes locked cylinder 15, and locked cylinder 15 is positioned at lifting
The downside of platform 4, the cylinder rod end set of locked cylinder 15 have the locking teeth 16 coordinated with rack 11；The brake assemblies include
Two brake oil cylinders 17 for being arranged on 12 both sides of brake rib, brake oil cylinder 17 are located at the downside of lifting platform 4, the oil of brake oil cylinder 17
Cylinder rod end set has the brake block 18 coordinated with brake rib 12.
And when chain rupture occurs, lifting platform 4 can produce anxious pendant, cause 14 high-speed rotation of gear coordinated with rack 11, speed
When the velocity of rotation that degree sensor 13 detects gear 14 is more than setting value, host is fed back to, host computer control brake oil cylinder 17 works,
Coordinate with brake rib 12 and carry out brake deceleration, until lifting platform 4 stops dropping, velocity sensor 13, which detects gear 14, to be stopped, then
Host computer control locked cylinder 15 promotes locking teeth 16 to coordinate with rack 11, is locked.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
