Description

Special adjustment device and method of use for construction of reserved grooved track for trams

[technical field]

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]

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 large engineering volume and high precision requirements. need. At present, there is no special reserved groove track adjustment device in our country, which is almost blank in this construction field. Therefore, a special track adjustment device is urgently needed to meet the requirements of the reserved groove track adjustment construction of the main line of the tram. .

[Content of the invention]

The object of the present invention is to: design a kind of special-purpose track adjustment device for track construction state of tram, solve the special problem that the reserved groove type track adjustment exists, realize the support, erection of the reserved groove type track, vertical Orientation and horizontal adjustment.

In order to achieve the above purpose, a new type of track construction state adjustment device is designed, which is mainly composed of three parts: beam, support part, and rail bearing groove, as shown in Figure 1. A set of supporting parts is welded symmetrically at both ends of the beam, with the midpoint of the beam as the reference, and a channel steel suspender group is welded vertically at each end. A top screw nut is relatively welded in the groove at the lower end of the opposite channel steel sling, and a round hole is provided at the corresponding position of the web to pass through the installation top wire, and the bottom flange of the channel steel sling is provided with a bolt hole for Connect and install the supporting rail groove to form the whole adjusting device.

Weld an M20 top screw nut in the groove at the lower end of the channel steel sling, and design a round hole at the corresponding position of the web to pass through the installation of the top wire. The bottom flange of the channel steel sling is designed with a Φ14mm bolt hole, which is used as a connection to the detachable bottom plate, such as Figure 2 shows.

The supporting part is composed of a lead screw mounting seat, a lead screw and an ear plate. One end of the lead screw mounting seat is welded with the lug plate, and the other end is welded with the beam square steel pipe. Tr50×3 trapezoidal threaded holes are designed on the lead screw mounting base. The length of the lead screw is about 320mm, the upper end is 60mm, the lower end is 50mm as the optical axis, the middle 210mm is designed with Tr50×3 trapezoidal thread, the upper end is designed with a Φ20 round hole, and the top is designed with a standard hexagonal head structure. A Φ20 round hole is designed on the ear plate. As shown in Figure 3.

The track groove consists of a pair of removable bottom plates and fixed bolt assemblies. Both ends of the detachable bottom plate are designed with Φ14mm bolt holes, which match the bolt holes at the bottom flange of the channel steel sling, and are connected to the channel steel sling through the fixing bolt assembly, which adopts M12 standard parts. As shown in Figure 4.

The method of using the special adjustment device for the reserved groove track construction of the tram.

1. First loosen the fixing bolts, remove the detachable bottom plate, separate the beam from the bearing groove, and then loosen the lead screw.

2. At the position where the rail adjustment device is pre-installed, erect the beam on the rail so that the left and right rails are respectively located in the middle of each pair of channel steel suspenders. Then insert the detachable bottom plate into the space at the bottom of the rail, and select the flat or slope surface of the detachable bottom plate according to the construction site conditions. Install the retaining bolt assembly so that the track supports the track. Install the top wires on the channel steel slings on both sides to make it bear against the rail waist. Finally, the lead screw is installed on the lead screw mounting seat so that it can withstand the foundation ground of the construction site. In this way, the erection of the rail adjustment device at the rail support position has been completed.

3. When adjusting the track, through the data obtained from measuring the geometric state of the track, the screw is rotated to make the adjustment device go up and down to realize the vertical adjustment of each rail. By rotating each pair of top screws, the horizontal adjustment and gauge adjustment of each rail are realized. The Φ20 round hole at the upper end of the lead screw is used for fine adjustment of the track by the booster rod. The hexagonal head structure on the top can be used for quick and rough adjustment with an electric wrench. Insert the pin shaft into the designed round hole of the ear plate to support the track support rod On the pin shaft, it can be used for lateral fixing of the track and the rail adjustment device. As shown in Figure 5.

Compared with the prior art, the present invention mainly has the following advantages:

1. Adopt channel steel sling-type rail support measures to solve the problem that the general rail adjustment device cannot be erected and adjusted during the construction of the reserved groove track for trams.

2. The top wires are arranged in pairs to realize the independent adjustment of each steel rail, which can save the gauge tie rods in the traditional method and facilitate rail adjustment construction.

3. The upper end of the lead screw is designed with a standard hexagonal head structure, which is convenient for quick and rough adjustment with an electric wrench. The lug plate is welded on the outside of the lead screw seat, which can facilitate the lateral fixing of the track and the rail adjustment device by the track support to ensure the accuracy of rail adjustment.

4. The rail bearing groove is designed as a detachable structure, which is convenient for the installation and disassembly of the adjustment device.

5. One side of the detachable bottom plate is designed as a flat slope, and the other side is designed as a 1/40 slope, which can meet the requirements of different tracks for the bottom slope of the rail.

5. Except for the lead screw and the trapezoidal threaded hole, all the structures of the device are designed as national standard parts to improve the versatility and maintainability of the device.
