Description
Technical field
The utility model is related to a kind of semitrailers, specifically, relate to a kind of fixing device of semitrailer side protection network.
Background technology
As shown in Figure 1, the fixed frame 9 that mainly includes of existing semitrailer side protection network fixing device, fixed iron 10, side are prevented
Fixation on protecting wire net indulges support 3 and reinforces stull 6 and forms, and fixed frame 9 is fixed on side bar 8, and fixed iron 10 is fixed on 7 bottom wing of longeron
On plate, 3 tops of fixed vertical support are fixed on fixed frame 9, are reinforced stull 6 and are fixed on fixed iron 10.Prevent traditional semitrailer side
Protecting wire net fixed frame has the disadvantages that：1. the side protection network retaining element quantity of a common semitrailer just there are as many as 30, hold
Easy to be lost, assembling inconvenience；2. side protection network fixed frame needs scene line and longeron lower wing plate side bar when making with weldering etc.
Process, production process are complicated；3. due to being welding between fixed iron and longeron lower wing plate, the lower wing plate for be easy to causeing weld should
Power is concentrated, and in actual use, is welded and fixed the longeron lower wing plate at iron and is susceptible to cracking phenomena.
In order to solve the problems, such as present on, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, so as to provide a kind of simple in structure, assembling simplicity, hold
Easily production, the fixing device of non-damageable semitrailer side protection network.
To achieve these goals, technical solution is used by the utility model：A kind of semitrailer side protection network is consolidated
Determine device, more including side protection network and on Trailer type frame for use in vehicle run through beam, and the side protection network includes shield frame and fixation
Support is indulged in fixation on the shield frame, the fixation indulge support top by fastening bolt be fixed on it is described run through beam outer end, it is described
The lower hinge of fixed vertical support has reinforcing diagonal brace, and the other end for reinforcing diagonal brace is screwed with described through beam.
Based on above-mentioned, the fastening bolt includes upper fastening bolt and lower fastening bolt.
Based on above-mentioned, the diagonal brace and the angle of horizontal direction reinforced is 30 °~60 °.
Based on above-mentioned, the Trailer type frame for use in vehicle includes two longerons and the side bar of both sides, is each passed through described in more through beam
It is connected after two longerons with the side bar of both sides, the top of the every longeron is both provided with upper flange, and beam pair is run through described in every
Each curved recessed portion should be respectively arranged with down by the upper flange.
The utility model compared with the prior art have substantive distinguishing features and progress, specifically, the utility model by
What is needed opens up threaded mounting hole on beam, and the fixation directly is indulged support by helicitic texture and the reinforcing diagonal brace is fixed
On beam, had the following advantages compared with traditional side protection network mounting means：1. retaining element is only several screws, greatly
Simplify assemble flow greatly；2. in the production process, eliminating scene line, matching somebody with somebody the processes such as weldering with longeron lower wing plate side bar, make
Its production is more easy；3. not contacted with longeron lower wing plate, longeron lower wing plate is avoided to crack.Further, by the fastening spiral shell
Bolt is arranged to arrange up and down two sets, makes it more firm by two fixed.Further, by the reinforcing diagonal brace and level
The angle in direction is arranged to 30 °~60 °, makes the stress that the reinforcing diagonal brace is subject to moderate, the stability of side protection network is more preferable.Its
Have the advantages that simple in structure, assembling is easy, easily produce, be hardly damaged.
Description of the drawings
Fig. 1 is existing semitrailer side protection network fixture structure schematic diagram.
Fig. 2 is the fixture structure schematic diagram of semitrailer side protection network in the utility model.
In figure：1. through beam；2. protect frame；3. fix vertical support；4. reinforce diagonal brace；5. fastening bolt；6. it reinforces horizontal
Support；7. longeron；8. side bar；9. fixed frame；10. fix iron.
Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
As shown in Fig. 2, a kind of fixing device of semitrailer side protection network, including side protection network and on Trailer type frame for use in vehicle
More through beam 1, support 3 is indulged in the fixation that the side protection network includes shield frame 2 and is fixed on shield frame 2, and 3 tops of fixed vertical support lead to
It crosses fastening bolt 5 to be fixed on through the outer end of beam 1, the lower hinge of fixed vertical support 3, which has, reinforces diagonal brace 4, reinforces the another of diagonal brace 4
End through beam 1 with being screwed；By being opened in the threaded mounting hole run through on beam 1, fixed vertical support 3 can be directly anchored to pass through
It wears on beam 1, without increasing fixed frame on side bar again, reinforces diagonal brace 4, constitutes a triangle through beam 1 and fixed vertical support 3
Shape makes the side protection network more securely attached.
When specifically used, needing to have opened up threaded mounting hole on beam 1 at installation side protection network in advance, afterwards will
It is mounted on through beam 1 on semi-trailer frame；In installation side protection network, fastening bolt 5 is first passed through by 3 tops of fixed vertical support with passing through
It wears 1 outer end of beam to fix, then the other end for reinforcing diagonal brace 4 is completed into installation with being screwed through beam 1.
In order to make installation more secured, fastening bolt 5 is made of upper fastening bolt and lower fastening bolt；It is in use, fixed
3 tops of vertical support avoid it around some rotation there are two fixed point.
In order to make support effect more preferable, it is 30 °~60 ° to reinforce diagonal brace 4 and the angle of horizontal direction；In use, it reinforces oblique
The stress distribution that support 4 and fixed vertical support 3 are subject to is more average, and the support effect for reinforcing diagonal brace 4 is more preferable.
In order to mitigate vehicle frame weight, the Trailer type frame for use in vehicle includes two longerons 7 and the side bar 8 of both sides, and more are divided through beam 1
It Chuan Guo not be connected after two longerons 7 with the side bar 8 of both sides, the top of every longeron 7 is both provided with upper flange, and every runs through beam 1
Corresponding each upper flange is respectively arranged with down curved recessed portion；Two it is described under curved recessed portion setting, ensure vehicle frame it is strong
On the premise of degree, weight is alleviated.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：It can still modify to specific embodiment of the present utility model or some technical characteristics are equally replaced
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
Among scope.
