- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：
A kind of telescopic device of highway bridge guardrail, it is left including left guardrail pedestal 1 and the right guardrail pedestal 4 being oppositely arranged
The right side of Guard fence base 1 is installed on left connecting plate 2, and the side of the left connecting plate 2 passes through fastening bolt 6 and 1 stationary phase of left guardrail pedestal
Even；The left side of right guardrail pedestal 4 is installed on right connecting plate 5, and the side of the right connecting plate 5 is solid by fastening bolt 6 and right guardrail pedestal 4
It is fixed to be connected；The right side central of left connecting plate 2 is fixedly connected with sleeve 3, and the inner cavity of the sleeve 3 is mounted with spring 8, and the one of spring 8
End is fixedly connected on the side of left connecting plate 2；Front and the back of sleeve 3 are fixedly connected with the limited block 35 of rectangular configuration, should
The side at 3 top of sleeve offers the slide opening 31 of rectangular configuration；The setting of slide opening 31 can carry out 7 integral telescopic length of pedestal
It limits, prevents 7 transition of pedestal from stretching into sleeve 3, so that there is situation about damaging under the shoring of 7 transition of pedestal in spring 8, from
And spring 8 is protected, the service life of spring 8 is extended, the outer surface of sleeve 3 is intervally distributed with reinforcing rib 36, strengthens
The setting of muscle 36 can enhance the structural strength of sleeve 3, the resistance to compression cracking resistance of sleeve 3 be improved, so as to extend making for sleeve 3
With the time limit, the top of the sleeve 3 fits in the baffle 32 that 31 position of slide opening is installed on " C " shape structure, and the setting of baffle 32 can
Slide opening 31 is blocked, in the highway bridge guardrail telescopic device in use, the dust in the reduction external world enters in sleeve 3
Amount, and the top of baffle 32 is installed on connection bolt 33；The left side central portion of right connecting plate 5 is fixedly connected with pedestal 7, the pedestal 7
One end is actively plugged in sleeve 3；The side at 7 top of pedestal is spaced apart equipped with the bolt hole being threadedly coupled for connection bolt 33
71, which passes through slide opening 31 that pedestal 7 and baffle 32 are interconnected in one；The outer surface of pedestal 7 is located at
What 71 leftward position of bolt hole was socketed with circular configuration determines platform 72, this determines position of the side of platform 72 far from right connecting plate 5 and spring 8
One end be in contact；The position that the left side of right connecting plate 5 is located at 7 both sides of pedestal has been fixedly connected with and pulls and supports mechanism 9, this pulls and supports mechanism
9 include pulling and supporting column 91, be set to the external screw thread 92 pulled and supported on 91 column cap of column and being threadedly connected to the nut for pulling and supporting 91 column cap of column
93；The left end for pulling and supporting column 91 passes through limited block 35, and nut 93 is installed in the left side of the limited block 35；The outer surface annular of pedestal 7 point
Reinforcement block 73 is furnished with, the setting of reinforcement block 73 can carry out 7 both sides of pedestal firm support, reduce pedestal 7 and occur when in use
The probability of crack conditions, so as to extend the service life of pedestal 7, the side of the reinforcement block 73 is with pulling and supporting 91 side stationary phase of column
Even.
The bottom position that is in contact with baffle 32 of connection bolt 33 is installed on beam 34, and the setting of beam 34 can drop
The contact wear generated between low connection bolt 33 and baffle 32 uses the longevity so as to extend connection bolt 33 with baffle 32
Life, the outer surface of the connection bolt 33 are coated with anti-decaying paint, and the setting of anti-decaying paint can form anti-in 33 outer surface of connection bolt
Rotten layer reduces connection bolt 33 and is corroded when in use by water grading factors, so as to further extend connection bolt 33
Service life.
The circular hole of perforation is offered in the middle part of the side of limited block 35, the setting of circular hole, which can give, pulls and supports the offer placement of column 91
Position, embedded with wearing ring in the circular hole, the setting of wearing ring can reduce pulling and supporting column 91 and wear caused by circular hole, thus
It reduces and pulls and supports column 91 to abrasion caused by limited block 35, extend the service life of limited block 35.
The diameter for determining platform 72 is identical with the internal diameter of sleeve 3, and such setting, which can allow, to be determined platform 72 and be firmly connected to sleeve 3

Situation, so as to extend the service life of pedestal 7.
The outer surface for determining platform 72 is pasted with rubber pad, and the setting of rubber pad, which can reduce, determines platform 72 to mill caused by sleeve 3
Damage corrodes, so as to the service life of lengthening sleeve 3.
The block surface of limited block 35 location interval that is in contact with 3 outer surface of sleeve offers rectangular-shaped recess, recess
Setting can increase the degree of roughness on 35 surface of limited block, limited block 35 be allowed firmly to be connected to the outer surface of sleeve 3, the limiting
The installation position of block 35 is mutually perpendicular to pulling and supporting the installation position of column 91.
The utility model, which can utilize, pulls and supports column 91 across limited block 35 and under the cooperation of external screw thread 92 and nut 93, allows
It pulls and supports column 91 with what sleeve 3 consolidated pull and support by pedestal 7, so as to carry out at the reinforcing of horizontal direction sleeve 3 and pedestal 7
Reason so that sleeve 3 and pedestal 7 in the horizontal direction grafting more securely, pass through slide opening 31, connection bolt 33,71 and of bolt hole
The cooperation of baffle 32 can be connected in one between pedestal 7 and sleeve 3 using bolt 33 is connected, so as to sleeve 3 and even
The consolidation process of vertical direction is carried out between column 7, the fastness of grafting between sleeve 3 and pedestal 7 is greatly improved so that set
Cylinder 3, in use always in balance and the firm state being connected, effectively prevent the highway bridge guardrail to stretch with pedestal 7
Device occurs being detached from situation about detaching when in use between sleeve 3 and pedestal 7, and the longevity is used with pedestal 7 so as to extend sleeve 3
Life, and then extend the service life of the highway bridge guardrail telescopic device.
Operation principle：In use, when generating vibration due to driving is when factors on highway bridge, the vibration on Bridge guardrail
It passes on sleeve 3 and pedestal 7, due to pulling and supporting column 91, limited block 35, external screw thread 92 and the cooperation of nut 93 so that sleeve 3 is with connecting
Column 7 is firmly incorporated into one in the horizontal direction, utilizes the cooperation for connecting bolt 33, slide opening 31 and baffle 32 so that sleeve 3 with
Pedestal 7 is firmly incorporated into one in vertical direction, and sleeve 3 is allowed to combine closely with pedestal 7, the vibration for preventing Bridge guardrail from generating
Erosion wear is caused to sleeve 3 and pedestal 7, and using the spring 8 in sleeve 3, to reduce pedestal 7 to caused by sleeve 3
Vibration abrasion；Pedestal 7 can stretch according to 3 axial direction of vibration frequency dealing sleeve of Bridge guardrail, be reduced using spring 8
To damage caused by sleeve 3 when pedestal 7 stretches, when needing to safeguard the highway bridge guardrail telescopic device, it is only necessary to
Connection bolt 33 and nut 93 and fastening bolt 6 are removed, later removing sleeve 3 and pedestal 7 in opposite direction can be into
Row is safeguarded.
In summary：The utility model by the limited block 35 of setting, pull and support mechanism 9, sleeve 3, slide opening 31, connection bolt
33rd, baffle 32, pedestal 7 and bolt hole 71 improve the external structure of the highway bridge guardrail telescopic device, solve and using
In the process, the fastness of grafting is poor between sleeve 3 and pedestal 7, leads to highway bridge guardrail telescopic device sleeve 3 when in use
Occur being detached from situation about detaching between pedestal 7, affecting sleeve 3 and pedestal 7 and the highway bridge guardrail telescopic device makes
The problem of with the service life.
