Description

Channel type adjustable base for installing contact net support column

Technical Field

The utility model relates to an electronic railway, in particular to adjustable base of channel type for installing contact net pillar.

Background

Along with the rapid development of the electrified railway in China, the installation accuracy of the contact network strut is higher and higher, and the requirements of a contact network side surface limit and a contact network strut assembly must be strictly met during construction so as to meet the suspension installation of the contact network.

At present, traditional contact net pillar mounting means is pre-buried rag bolt earlier usually, then be fixed in the contact net pillar on the rag bolt, this mode is because rag bolt pre-buried back position is fixed completely, it is less to lead to contact net pillar adjustment range, and rag bolt is difficult to control at pre-buried in-process precision, the condition that the accurate unable assemblage pillar in rag bolt pre-buried position and contact net pillar invade railway clearance often appears, the later stage can only be handled through the mode of pouring basis again or pre-buried rag bolt again, not only the construction degree of difficulty is big, engineering cost is high and seriously influence construction period.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a channel type adjustable base for installing the contact net pillar is provided to greatly improve the flexibility of contact net pillar installation, show and improve contact net pillar installation effectiveness.

The utility model provides a technical scheme that its technical problem adopted as follows:

the utility model discloses an adjustable base of channel type for installing contact net pillar, characterized by: the top surfaces of the left channel and the right channel are parallel to the surface of the contact net foundation, and are provided with through slot-shaped openings, and the heads of T-head bolts for fixedly mounting contact net pillars are positioned in the slot cavities of the left channel and the right channel; the left side channel and the right side channel are connected into a whole through a connecting component and are connected with the contact net foundation concrete in an anchoring mode through an anchoring component.

The utility model has the advantages that the left side channel and the right side channel are used as the foundation of the contact net support, and the contact net support is fixed and installed through the T-head bolt, so that the side limit of the contact net support can be adjusted within the range of the channel at will and flexibly along the vertical line direction, the flexibility of installation of the contact net support is greatly improved, and the contact net support is prevented from invading the railway limit; the left channel and the right channel are connected into a whole through the connecting component, so that the positions of the channels can be accurately fixed according to the distance between the bolt holes of the contact net support along the line, and the condition that the contact net support cannot be assembled due to the dislocation of the positions of the two channels can be effectively avoided; the device has the characteristics of reasonable structure, convenience and quickness in construction and installation, flexibility in adjustment, strong universality and easiness in maintenance, can obviously improve the installation efficiency of the contact net support, and can be widely applied to the construction of various electrified railways.

Drawings

The specification includes the following three drawings:

fig. 1 is a sectional view (longitudinal direction) of a channel type adjustable base of a contact net support of the utility model;

fig. 2 is a cross-sectional view (transverse) of the channel-type adjustable base of the contact net support of the present invention;

fig. 3 is a partially enlarged view a of fig. 2.

The figures show the components and corresponding references: the contact net comprises a contact net support 10, a stiffening rib 11, a base flange 12, a T-shaped head bolt 13, a left channel 21, a right channel 22, a flat steel 23, an I-shaped anchor rod 24 and a contact net foundation 30.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Referring to fig. 1 to 3, the utility model discloses an adjustable base of channel type for installing contact net pillar, including pre-buried left side channel 21, the right side channel 22 that parallels and perpendicular to circuit direction in contact net basis 30 a pair of, left side channel 21, the top surface of right side channel 22 parallels with contact net basis 30 surface, and sets up the cell type opening of leading to long for the head of the T head bolt 13 of installation fixed contact net pillar 10 is located the vallecular cavity of this left side channel 21, right side channel 22. The lower extreme welding of contact net pillar 10 sets up base flange 12, and the mounting through-hole that supplies T head bolt 13 upper portion to pass is established to the spacing face on the face of base flange 12. The left side channel 21 and the right side channel 22 are connected into a whole through a connecting component and are connected with the contact net foundation 30 through an anchoring component in a concrete anchoring mode. The left channel 21 and the right channel 22 are used as the basis of the contact net support post 10, the contact net support post 10 is fixedly installed through the T-head bolt 13, the side limit of the contact net support post 10 can be adjusted within the range of the channel randomly and flexibly along the vertical line direction, the installation flexibility of the contact net support post 10 is greatly improved, and the contact net support post 10 is prevented from invading the railway limit.

The connecting component is flat steel 23 arranged along the length direction of the left channel 21 and the right channel 22 at intervals, and two ends of the flat steel 23 are respectively welded with the bottom surfaces of the left channel 21 and the right channel 22. Can be according to the accurate fixed channel position of the distance between the contact net pillar 10 in the same direction as the circuit bolt hole, the condition that can effectually avoid two channel position dislocation can't assemble the contact net pillar appears.

Referring to fig. 1 and 2, the anchoring member is an i-shaped anchor bar 24 spaced along the length of the left and

right channels

21 and 22, and the i-shaped anchor bar 24 is welded and fixed to the bottom surface of the left or

right channel

21 or 22.

The above is only used for illustrating some principles of the channel type adjustable base for installing the contact net support column of the present invention, and the present invention is not limited to the specific structure and the application range shown and described, so all the corresponding modifications and equivalents that may be utilized all belong to the patent scope applied by the present invention.
