Abstract
The application is related to a kind of mechanical hoisting mechanism with front and rear double brake, including mechanical elevator, it is characterized in that the mechanical elevator is provided with two sets of disc brakes, wherein a set of disc brake is provided with hand switch, is operated with manual switches control disc brake action；Another set of disc brake is provided with service brake arrangement, controls the disc brake to act by service brake arrangement.Disc brake of the application with hand switch is normally closed type disc brake, and normally closed type disc brake is as safety guard, and it is mainly by hand switch control；Disc brake with service brake arrangement is disc brake open in usual, and disc brake open in usual is as service brake, and it is controlled mainly by pin.The application compared with prior art, with advantages below and effect：Reasonable in design, can be with walking be carried, and more renewal of facing renewal is simple, band hydraulic failure protection, safe and reliable.
Description
Technical field
The application is related to a kind of mechanical hoisting mechanism with front and rear double brake, is primarily adapted for use in the strong of ground base construction
Tamping machine.
Background technology
The dynamic compaction machinery overwhelming majority's on the market is the built-in hydraulic pressure elevator of reductor, by reductor inside multiple-piece
Friction disc brake, in strong rammer field, this working frequency is high, impacts under big operating mode, and internal friction piece is easy to damage, and changes
Friction plate is extremely inconvenient, is more to change reductor assembly, poor reliability, cost is high.The single disc brake open in usual of traditional band
The mechanical hoisting mechanism of braking, it is impossible to which band carries walking, without hydraulic failure protection brake, there is certain potential safety hazard.
The content of the invention
The application's aims to overcome that above shortcomings in the prior art, and provides a kind of reasonable in design,
Can be with walking be carried, more renewal of facing renewal is simple, band hydraulic failure protection, the safe and reliable mechanical elevator with front and rear double brake
Mechanism.
The application used technical scheme that solves the above problems is：The mechanical hoisting mechanism with front and rear double brake,
Including mechanical elevator, it is characterized in that the mechanical elevator is provided with two sets of disc brakes, opened manually wherein a set of disc brake is provided with
Close, be operated with manual switches control disc brake action；Another set of disc brake is provided with service brake arrangement, and the disc brake is controlled by service brake arrangement
Action.
Disc brake of the application with hand switch is normally closed type disc brake, and normally closed type disc brake is as safety guard, and its is main
By hand switch control；Disc brake with service brake arrangement is disc brake open in usual, and disc brake open in usual is as service brake, and its is main
Controlled by pin.Mechanical elevator is arranged on mechanical elevator mounting platform, and normally closed type disc brake installs flat with mechanical elevator
Platform is connected, and disc brake open in usual is connected with mechanical elevator mounting platform.When needing band to carry walking, it is only necessary to click hand
Normally closed type disc brake is in closure state by dynamic switch, it is possible to is securely achieved band load and is walked.Run into hydraulic system fails
Oil cylinder decompression inside situation, normally closed type disc brake, spring reset braking closure, plays safeguard protection effect.
The application compared with prior art, with advantages below and effect：Reasonable in design, can be with walking be carried, more
Renewal of facing renewal is simple, band hydraulic failure protection, safe and reliable.
Brief description of the drawings
Fig. 1 is the front view of the embodiment of the present application.
Fig. 2 is Fig. 1 schematic top plan view.
Fig. 3 is the schematic perspective view of the embodiment of the present application.
In figure：1 is rearmounted normally closed type disc brake, and 2 be mechanical elevator, and 3 be preposition disc brake open in usual, and 4 be mechanical
The bearing block of elevator.
Embodiment
The application is described in further detail below in conjunction with the accompanying drawings and by embodiment, following examples are to this Shen
Explanation please and the application is not limited to following examples.
Referring to Fig. 1~Fig. 3, the present embodiment is the mechanical hoisting mechanism with front and rear double brake.Mechanical elevator 2 passes through two
The bearing block 4 of side is connected with 6 bolts and the mounting platform of mechanical elevator 2, and normally closed type disc brake 1 passes through 5 bolts on bottom plate
With the connection of the mechanical mounting platform of elevator 2, disc brake 3 open in usual passes through 6 bolts and the mounting platform of mechanical elevator 2 on bottom plate
Connection.
The elevator type of the present embodiment is mechanical elevator, without brake apparatus inside the reel of mechanical elevator 2, its
Braking relies primarily on front and rear double brake.Its main operational principle is：When equipment be in stopped status under, at normally closed type disc brake 1
In closure state, mechanical elevator 2 is the state of braking.When equipment is started working, opening is first operated with manual switches normally closed
Formula disc brake 1, then controls disc brake 3 open in usual to close, holds suspension hook, then connect power source by service brake arrangement, mechanical volume
2 actions for realizing lifting with suspension hook by steel wire rope are raised, when midway temporary needs suspension hook is stopped, by stepping on service brake arrangement,
Control disc brake 3 open in usual to realize braking, when needing suspension hook to continue to lift up, unclamp service brake arrangement disc brake 3 open in usual and open, suspension hook
Continue to lift up；When needing to realize that suspension hook is braked in the air for a long time, can be operated with manual switches makes normally closed type disc brake 1 be in system
Dynamic state, i.e. suspension hook are checked.If without normally closed type disc brake 1, to realize band carry walking will a pin slam brake, one
Pin controls throttle, easily controls and bad security incident occurs.But with double disc brakes, manual closing normally closed type disc brake 1 is only needed,
Check weight in the air, it is possible to which a foot control liquefaction door is walked, you can carry walking to securely achieve band.
The present embodiment normally closed type disc brake 1 only needs to open hand switch, disk brake caliper is in open configuration, friction plate is just
Can be released direct replacing, very simply；Disc brake 3 open in usual only needs to unload eight bolts of downside（Referring on the right of Fig. 1）,
Friction plate can be just changed, it is very convenient.The time was so not only saved but also replacement cost can be saved.
Simple deformation or the combination of every present techniques feature and technical scheme, it is considered that fall into the protection of the application
Scope.
