Abstract
The utility model provides a kind of safety guard of double-layer trolley weighing device; corresponding position is equipped at least two pairs guard bars and hollow pipe that can be nested together in upper trolley and lower layer's trolley; the internal diameter of hollow pipe is greater than the outer diameter of guard bar, and guard bar and hollow pipe are respectively fixedly connected in upper trolley and lower layer's trolley.Structure is simple, processing and fabricating is simple.
Description
Technical field
The utility model relates to double-layer trolley weighing more particularly to a kind of safeguard protection of double-layer trolley weighing device dresses
It sets.
Background technique
With the development of science and technology, the required precision that many enterprises weigh to crane is higher and higher, and double-layer trolley claims
Weight form can high degree improve weighing precision.Weighing sensor coupling part mechanical strength is than relatively thin between double-layer trolley
It is weak, it is also necessary to additional safety guard, with the safety of assurance mechanism.The effect of attachment device is that crane or trolley exist
When starting or braking, trolley and load have the inertial impact force of biggish vertical or horizontal horizontal direction, to prevent sensor
Damage causes upper trolley disengaging that accident occurs, and need to install safety guard additional.Existing safety guard structure is hinged
Mode, upper and lower level vehicle frame, which is respectively welded two, hole pedestal, by pin shaft and intermediate screwed single solid steel axis connection, no
But structure is complicated, and is required to machine, so the period is long, it is at high cost.
Utility model content
To solve the above problems, the utility model provides a kind of safety guard of double-layer trolley weighing device, structure
Simply, processing and fabricating is simple.
The technical solution of the utility model are as follows: a kind of safety guard of double-layer trolley weighing device, upper trolley with
Corresponding position is equipped at least two pairs guard bars and hollow pipe that can be nested together on lower layer's trolley, and the internal diameter of hollow pipe is greater than
The outer diameter of guard bar, guard bar and hollow pipe are respectively fixedly connected in upper trolley and lower layer's trolley.
The internal diameter diameter of hollow pipe and the outer diameter difference in diameter of guard bar are 16-24mm.
The internal diameter diameter of hollow pipe and the outer diameter difference in diameter of guard bar are 20mm.
The bottom of frame of upper trolley is fixedly connected at least two guard bars, the upper plane corresponding position of lower layer's trolley
It is fixedly connected with the hollow pipe that internal diameter is greater than guard bar outer diameter.
Guard bar is hollow pipeline, saves material and cost.
Guard bar is uniformly distributed along the bottom of frame of upper trolley, is connect with the bottom of frame of upper trolley.
Guard bar is seamless steel pipe, and hollow pipe is seamless steel pipe.Seamless steel pipe intensity is high, the convenient vehicle frame with upper trolley
Bottom, lower layer's trolley upper plane be welded to connect, the connection with the bottom of frame, the upper plane of lower layer's trolley of upper trolley
It is convenient.
The beneficial effects of the utility model, safety guard provided by the present application, when installation, only need to be by upper layer guard bars
It both can be inserted into lower hollow pipe, there are gap appropriate between guard bar and hollow pipe, make to protect during normal weigh
Bar is not contacted with each other with hollow pipe, when sensor surprisingly fails as being broken, is played a protective role.Safety provided by the present application is protected
Protection unit compares existing safety guard, and structure is simple, processing and fabricating is simple, used raw material cost is low, up and down
Layer get off between when being nested together by the steel pipe of different-diameter, it is simple and fast.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of double-layer trolley weighing device, upper trolley 1, installation including erection crane lifting mechanism
Lower layer's trolley 2 of crane travelling gear, the weighing sensor 3 being mounted between upper trolley 1 and lower layer's trolley 2 and safety are protected
Protection unit.Safety guard includes at least two pairs guard bars and hollow pipe that can be nested together, guard bar and hollow pipe point
It is not fixedly connected on upper trolley 1 and lower layer's trolley 2.The internal diameter of hollow pipe is greater than the outer diameter of guard bar, and hollow pipe is interior
The outer diameter difference in diameter of diameter diameter and guard bar is 16-24mm, is preferentially 20mm.
Such as, the bottom of frame of upper trolley 1 is fixedly connected at least two guard bars 5, and the upper plane of lower layer's trolley 2 is corresponding
The hollow pipe 6 that internal diameter is greater than guard bar outer diameter is fixedly connected at position.
Or the bottom of frame of upper trolley is fixedly connected at least two hollow pipes, the upper plane of lower layer's trolley corresponds to position
The place of setting is fixedly connected with the guard bar that outer diameter is less than hollow bore.
The bottom of frame of upper trolley 1 is fixedly connected with connecting plate I 7, and the upper plane corresponding position of lower layer's trolley 2 is fixed
It is connected with connecting plate II 8, connecting plate I is fixed with guard bar 5 or hollow pipe 6, and connecting plate II is corresponding to be fixed with hollow pipe 6 or protection
Bar 5.
Guard bar is hollow pipeline, saves material and cost.
Guard bar is uniformly distributed along the bottom of frame of upper trolley, is connect with the bottom of frame of upper trolley.
The material of guard bar be steel, and guard bar be hollow pipeline when, guard bar may be seamless steel pipe.It is hollow
Pipe is steel pipe, preferably seamless steel pipe.Seamless steel pipe material can be Q235B, and intensity is high, the convenient vehicle frame bottom with upper trolley
Portion, lower layer's trolley upper plane be welded to connect, the connection side with the bottom of frame of upper trolley, the upper plane of lower layer's trolley
Just.
The beneficial effects of the utility model, safety guard provided by the present application, when installation, only need to be by upper layer guard bars
It both can be inserted into lower hollow pipe, there are gap appropriate between guard bar and hollow pipe, make to protect during normal weigh
Bar is not contacted with each other with hollow pipe, when the unexpected failure of weighing sensor 3 is as being broken, is played a protective role.It is provided by the present application
Safety guard compares existing safety guard, and structure is simple, processing and fabricating is simple, the used cost of raw material
It is low, upper and lower level get off between when being nested together by the steel pipe of different-diameter, it is simple and fast.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
