Brief description of the drawings
Fig. 1 is the structural representation for applying powder truck spreader of the present utility model；
Fig. 2 is Fig. 1 partial enlarged drawing.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment：
Reference picture 1-2, powder truck spreader Weighing device described in the present embodiment, including weight display 2, weighing and sensing
Device 9, connecting square pipes 5 and rubber blanket 10.The weighing sensor 9 be located at connecting square pipes 5 lower section, and by connecting bolt 6 with
Connecting square pipes 5 are fixedly connected；The rubber blanket 10 is located at the lower section of weighing sensor 9, in the two ends of weighing sensor 9 and rubber
Steel plate 8 is respectively equipped between pad 10；The weighing sensor 9, steel plate 8 are connected with rubber blanket 10 by fastening bolt 7；It is described
Weighing sensor 9 is connected with weight display 2 by data wire, and the data message weighed is sent into display of weighing in real time
Device 2.
Powder truck spreader Weighing device described in the utility model when mounted, as shown in figure 1, by weight display 2
It is fixed in driver's cabin 1, to facilitate real-time monitoring；Connecting square pipes 5 are weldingly fixed on to the bottom in powder railway carriage or compartment 3；By weighing and sensing
Device 9, steel plate 8 and rubber blanket 10 are fixed on vehicle frame 4 by fastening bolt 7.Counted weight, and will claimed by the rewinding of weighing sensor 9
The data message of weight is sent to weight display 2 in real time, and shows instant material position by weight display 2, expects full automatic alarm, and
Conversed according to construction requirement and spread paving product, paving standard, and display current residual weight of material in real time are spread in inspection.
【Connection between powder railway carriage or compartment 3 and vehicle frame 4 is calculated】：
Below so that the volume of powder railway carriage or compartment 3 is 12m3 as an example, the security of powder truck spreader Weighing device is verified.
The load-bearing of each weighing sensor 9 is 9 tons, needs to install four weighing sensors 9 according to calculating.
Be attached fixation with fastening bolt 7 between weighing sensor 9 and vehicle frame 4, weighing sensor 9 and vehicle frame 4 it
Between be lined with rubber blanket 10, it is possible to increase frictional force, eliminate contact surface between gap.
The fastening bolt 7 of totally 8 M27 is connected between powder railway carriage or compartment 3 and vehicle frame 4, the performance rate of bolt is 8.8 grades, and it is twisted
Clamp force square is 663Nm, and the pretightning force of each bolt is P0.
According to formula：
M=K × P0 × d × 10-3
In formula：
M --- screw-down torque, Nm；
K --- moment coefficient, K=0.284；
P0 --- pretightning force, kN；
D --- the diameter of thread, mm.
So 663=0.284 × P0 × 27 × 10-3
Then P0=86.5kN
The coefficient of friction of rubber blanket 10 takes the pretightning force of 0.6,8 fastening bolts 7 to cause between powder railway carriage or compartment 3 and chassis member
The frictional force Q1 of generation：
Q1=8 × 0.6 × 86.5=415.2kN=41.52 (T)
The frictional force Q2 that fully loaded powder railway carriage or compartment 3 and its deadweight is produced：
Q2=15000 × 0.6=9000kg=9.0 (T)
The maximum longitudinal inertia force W in fully loaded powder railway carriage or compartment 3 and its deadweight：
W=15000 × 2=30000kg=30 (T)
Q=Q1+Q2=41.52+9=50.52 ＞ 30=W
Therefore the frictional force between powder railway carriage or compartment 3 and vehicle frame 4 disclosure satisfy that requirement.
According to GB/T 3098.1-2000《Fastener mechanical performance bolt, screw and stud》Table 7 understands 8.8 grades of M27 spiral shells
The guarantee load of bolt is 86.5kN.
86.5 × 8=692kN=69.2 (T) ＞ 50.52 (T)
Therefore the bonding strength of 8 fastening bolts 7 is to meet to require.
General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry described in above-described embodiment and specification it should be appreciated that simply illustrate principle of the present utility model, not
On the premise of departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these change and changed
Enter and both fall within the range of claimed the utility model.The utility model be claimed scope by appended claims and
Its equivalent thereof.
