Abstract
The utility model provides a kind of plain bumper, effectively sandstone can be avoided to enter inside plain bumper, moreover it is possible to prevent from breaking down because sandstone falls into vibrating motor.Its technical solution is such that a kind of plain bumper, it includes table top, the table top is connect by elastic component with pedestal, it is characterized by: being equipped with eccentric shaft between the table top and the pedestal, the eccentric shaft is connected to motor by gimbal coupling, table top bottom surrounding is connected with baffle, and the eccentric shaft is connect by bearing with the baffle.
Description
Technical field
The utility model relates to tapping equipment technical field, specially a kind of plain bumper.
Background technique
Concrete is the maximum construction material of dosage in the world, have many advantages, such as it is sturdy and durable, low in cost, with machine
The fast development of tool, in order to improve the quality of concrete, needs its compactness to reach design and wants before concrete comes into operation
It asks, jolt ramming is carried out to it usually using plain bumper.
Traditional plain bumper may be fallen into inside plain bumper in the sandstone sputter when jolt ramming causes cleaning inconvenient,
And traditional plain bumper is connect with table top by vibrating motor and realizes vibration to which the vibration for generating vibrating motor passes to table top
Dynamic, if sandstone splashes, sandstone, which may be fallen into, to be caused to break down in vibrating motor.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of plain bumper, effectively sandstone can be avoided to enter in plain bumper
Portion, moreover it is possible to prevent from breaking down because sandstone falls into vibrating motor.
Its technical solution is such that a kind of plain bumper comprising table top, the table top are connected by elastic component and pedestal
Connect, it is characterised in that: eccentric shaft is installed between the table top and the pedestal, the eccentric shaft by gimbal coupling with
Motor connection, table top bottom surrounding are connected with baffle, and the eccentric shaft is connect by bearing with the baffle.
It is further characterized by:
Excentric sleeve is socketed on the outside of the eccentric shaft；
The elastic component is set on the outside of the baffle, and the elastic component is rubber air spring, the rubber air bullet
Spring is connect by attachment base with pedestal, and the attachment base is welded on the pedestal；
The table top is magnechuck.
After with such a structure, eccentric shaft turns are driven by motor to generate vibration, vibration is passed by baffle
The vibration that table top realizes table top is passed, it will be inside plain bumper and outer portion is every stopping sandstone, avoid by setting baffle
Sandstone is flown into inside plain bumper, by the way that motor is installed on outside, keeps motor remote by increasing the length of gimbal coupling
From plain bumper, sandstone is avoided to impact motor；Further, by using rubber air spring rather than as traditional spiral shell
The spring for revolving shape, can be avoided sandstone and be stuck in spiral spring leads to damage spring, weakens the generation of the phenomenon that spring.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
A kind of plain bumper as shown in Figure 1 comprising table top 1, table top 1 are magnechuck, and 1 bottom surrounding of table top passes through rubber
Glue air spring 2 is connect with pedestal 3, and eccentric shaft 4 is equipped between table top 1 and pedestal 3, and the quantity of eccentric shaft 4 is more than or equal to one
It is a, excentric sleeve 5 is socketed on the outside of eccentric shaft 4, eccentric shaft 4 is connect by gimbal coupling 6 with motor 7, and motor 7 is frequency conversion
Motor, 1 bottom surrounding of table top are welded with baffle 8, there are certain interval between 3 upper surface of baffle 8 and pedestal, prevent from that biography will be vibrated
It is delivered on pedestal 3, the through-hole connecting for gimbal coupling 6 with eccentric shaft 4 is offered on baffle 8, eccentric shaft 4 passes through through-hole
And it is connect by bearing with baffle 8.
Its working principle is that: drive the rotation of eccentric shaft 4 to generate vibration by variable-frequency motor 7, vibration is transmitted to by baffle 8
It is vibrated on table top 1, and the setting of baffle 8 can also stop sandstone to fly into plain bumper, by the way that motor 7 is installed on jolt ramming
On the outside of platform, makes motor 7 far from plain bumper by increasing the length of gimbal coupling 6, sandstone is avoided to cause shadow to motor 7
It rings, by using rubber air spring 2 rather than as traditional spiral helicine spring, can be avoided sandstone and be stuck in spiral spring
In cause damage spring, weaken spring the phenomenon that generation, in addition rubber air spring 2 also have high-frequency vibration isolation, sound insulation with
And the advantage that the natural frequency of vibration is low, it can preferably realize vibration isolation；And using magnechuck as table top 1, it only need to be by cast iron die trial
(being not drawn into figure) is placed on table top, so that it may the fixation of table top 1 Yu die trial is completed, and removing also need to only eliminate table top 1
Magnetism can be removed very convenient.
Further, rubber air spring 2 is connect by attachment base 9 with pedestal 3, and attachment base 9 is welded on pedestal 3, even
Joint chair 9 and rubber air spring 2 are located at 8 outside of baffle, using such structure, if table top 1 is because vibration occurs for a long time
The baffle 8 of offset, 1 bottom of table top prevents table top 1 because occurring because being stopped by the attachment base 9 being welded on pedestal 3
Excessive offset leads to not reset, and the distance between baffle 8 and attachment base 9 are smaller, and the offset of table top 1 is with regard to smaller.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, any people for being familiar with the technology is in the technical scope disclosed by the utility model, and any changes or substitutions that can be easily thought of,
It should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with claim
Subject to protection scope.
