Description
Technical field
The present invention relates to concreting machinery field, more particularly to a kind of concrete pump with lift hopper fence.
Background technology
Concrete pump is a kind of efficient concrete conveyer, is widely used in skyscraper, colliery, mine, tunnel
The concrete workses such as road, railway, highway, bridges and culverts, harbour, water conservancy, electric power, defence engineering.It passes through pipeline by concrete continuous
Cast scene is sent to, with preferable maneuverability.
Concrete pump needs dumping into concrete pump hopper for concrete conveyance tank car continuation in pump concrete
Concrete, to prevent big material from entering material bin and job safety, typically can design cell structure formula at the upper surface of hopper
Fence, its Main Function is to prevent the excessive material in concrete mortar from entering in material bin, while being also a kind of security protection
Device, plays certain safeguard protection effect.But the setting of fence limits to a certain extent concrete and enters in material bin
Speed, easily makes concrete be deposited on fence, causes concrete to overflow, and affects the transfer efficiency of concrete.
At present domestic conventional solution is that operator pushes concrete with instruments such as spades at any time, dissipates concrete
Open and go forward side by side in material bin.Obviously, this working method not only increases the workload of operator, and inefficiency, also
Hidden danger is left to the personal safety of workman, is unfavorable for safety in production.
Therefore, the company such as external some concrete pump manufacturers such as CIFA, on hopper fence vibrating motor is arranged
Realize that fence vibrates.Vibration source (such as vibrating motor) is set specifically on fence, by direct on hopper fence
The mode for arranging vibration source (such as vibrating motor) drives fence to vibrate.This fence mode of vibration improves operating efficiency, reduces
Potential safety hazard, but due to need it is extra on concrete pump increase vibration source and appurtenances that some must increase, lead
Causing the cost of concrete pump increases, and is unfavorable for marketing；And the working environment of concrete pump is more severe, the vibration for newly increasing
Source increased to a certain extent equipment fault point, and its reliability is reduced；In addition, hopper fence upper space is limited, to coagulation
The design of native pump brings difficulty；Concrete pump cleaning is also add simultaneously and safeguards inconvenient, and then increased concrete pump
Maintenance cost.Therefore, above-mentioned shortcomings cause domestic concrete pump manufacturer not using this mechanism, still edge
Worked with the mode of original artificial exclusion concrete, wasted time and energy, inefficiency.
The concrete pump of Patent No. ZL201010127030.0 is shaken by cam driven fence, however, this vibrations
For rigid vibrations, the impact to concrete pump, hopper, fence is all very big, can substantially reduce concrete pump, hopper, fence
Service life, and, the frequency of this vibrations is relatively low, and concrete piles up problem still without thoroughly solution.
The content of the invention
Present invention aims to the deficiencies in the prior art, there is provided a kind of concrete with lift hopper fence
Pump, its vibrations are flexible shock, and the impact to concrete pump, hopper, fence is all very little, it is ensured that concrete pump, hopper,
The service life of fence, and, the frequency that it shakes is very high, and having thoroughly solve concrete to pile up problem, makes the concrete can
To rapidly enter in hopper, the smooth pumping of concrete is realized, the operating efficiency for making concrete pump is improved, and reliability is carried
It is high.
