Embodiment 1

[0032] Embodiment 1: The structural composition of the special adjustment device for track construction with reserved grooves for trams.

[0033] The overall structure of the present invention is composed of a beam 1, a support portion 2 and a rail bearing groove 3. The beam 1 is welded to the supporting part 2, and then connected to the detachable bottom plate 11 through the fixing bolt assembly 12 to form the whole device. As shown in Figure 1. Two ends of the beam 1 are symmetrically welded with a set of supporting parts 2, with the midpoint of the beam 1 as the reference, a channel steel suspender set is welded vertically at each end, and the pair of channel steel suspenders contains two oppositely standing channel steels Sling 5, a jackscrew nut 6 is relatively welded in the groove at the lower end of the channel steel sling 5 standing opposite to each other on the left and right, and a round hole is provided at the corresponding position of the web to pass through the i...

Embodiment 2

[0037] Embodiment 2: The method of using the special adjustment device for the reserved groove type track construction of trams.

[0038] 1. First loosen the fixing bolt 12, remove the detachable bottom plate 11, separate the beam 1 from the rail support groove 3, and then rotate the screw 9 to loosen it.

[0039] 2. At the position where the rail adjustment device is pre-installed on the track, erect the crossbeam 1 on the steel rail so that the left and right two steel rails are respectively located in the middle of each pair of channel steel suspenders 5 . Then insert the detachable base plate 11 in the space at the bottom of the rail, and select the flat or slope surface of the detachable base plate 11 according to the construction site conditions. The fixing bolt assembly 12 is installed so that the rail bearing groove 3 supports the track. Install the top wire 7 on the channel steel suspenders 5 on both sides to make it withstand the rail waist. Finally, the leading sc...

Abstract

The invention relates to a special regulating device for construction of trench-reserved tracks of tramcars and an application method of the special regulating device. The special regulating device consists of a cross beam, supporting parts and rail bearing channels, wherein a group of the supporting parts are symmetrically welded to two ends of the cross beam; based on the midpoint of the cross beam, two groups of channel steel harnesses are separately and vertically welded to the two ends of the cross beam; each group of the channel steel harnesses consists of a left channel steel harness and a right channel steel harness which are oppositely erected; two jackscrew nuts are separately and oppositely welded to grooves in the lower ends of the left channel steel harness and the right channel steel harness which are erected oppositely, and circular holes is formed in the corresponding positions of webs so that jackscrews penetrate through the circular holes to be mounted; bolt holes allowing the rail bearing channels to be connected and mounted are formed in wing plates at the bottoms of the channel steel harnesses, so as to form the whole regulating device. Compared with the prior art, the special regulating device disclosed by the invention has the advantage that a channel steel harness type rail bearing measure is adopted, so that the problem that a general rail regulating device for the construction of the trench-reserved tracks of the tramcars cannot be erected for rail regulation is solved.

Description

[technical field] [0001] The invention relates to the field of engineering technology and science, and relates to a device and an application method for adjusting the construction state of a tram reserved groove type track, which is specially used for adjusting the construction state of a reserved groove type track. [Background technique] [0002] In the construction of reserved grooved track for trams, due to the particularity of its structure, the usual rail adjustment device cannot be applied. In the construction of traditional reserved grooved track, the rail is usually suspended by a spreader, and wooden supports are used on both sides. Waiting for equipment to carry out small-scale rail adjustment construction. This traditional method is still applicable in the construction of small-scale station lines with relatively low precision requirements, but it is difficult to meet the requirements of construction quality and construction progress on the main line of trams with...
