Description

Track locking device

Technical Field

The utility model relates to a manufacture equipment technical field, in particular to be used in the rolling track locking device of prevention gyro wheel to a certain direction on the horizontal track.

Background

The application of rail transportation is very wide, and in order to ensure the safety of the rail car running on the rail, especially to limit the rail car running to a certain position, a rail locking device is generally arranged at an important part, so as to block the rail car and prevent the rail car from passing through. The existing track locking device is generally provided with a concave metal block, so that a recess is matched with the track in shape, a threaded through hole is arranged at the bottom of the recess, and the recess block is fixed on the track through a bolt. The rail locking device has the following two defects that the rail locking device must be installed from the broken end of the rail firstly, and if the distance between the broken end of the rail and the rail locking device is longer, the rail locking device needs to be slid to a locking position all the time, so that the rail locking device is inconvenient to install and disassemble; and secondly, the shape of the concave block is matched with that of the cross section of the track, and the processing requirement is high.

Disclosure of Invention

In order to solve the technical defects, the rail locking device is simple and reliable in structure, easy to operate and low in manufacturing cost.

The utility model provides a technical scheme that its technical problem adopted is: a rail locking device characterized by: the device comprises a support and a stop block, wherein the support is a U-shaped bending plate, Z-shaped hole grooves are formed in two bending edges of the support, the Z-shaped hole grooves in the two bending edges are completely overlapped, and the bottom end of the U-shaped bending plate of the support is fixedly connected with a rail car roller frame to be locked; the stop block is an L-shaped thick plate, a through hole is formed in the upper end of the stop block, a wedge surface is arranged at the bottom end of the stop block, the stop block is installed in a Z-shaped hole groove of the support through a pin shaft, a split pin and a check ring, the stop block is arranged in a U-shaped opening of the support, the check ring is an annular thin plate, the check ring is sleeved at two ends of the pin shaft, the check ring is respectively attached to the outer sides of the folded bent edges of the support, and the pin shaft outside the check ring is provided with the split pin.

As the preferred scheme of the utility model, dog upper end set up through-hole and 1 phase-match of round pin axle.

As the preferred scheme of the utility model, the diameter of retaining ring be greater than the width of Z type hole tank bottom.

The utility model has the advantages that compared with the prior art, the utility model has simple and reliable structure, simple and rapid operation, rapid and effective production, and effectively improved production efficiency; the utility model discloses a track locking device, low in manufacturing cost is honest and clean, can effectually save manufacturing cost.

Drawings

Fig. 1 is a schematic structural view (loosened state) of the present invention.

Fig. 2 is a schematic structural diagram (locked state) of the present invention.

In the figure: 1. the device comprises a pin shaft, 2, a split pin, 3, a retainer ring, 4, a support, 5, a stop block, 6 and a roller frame; 7. a track.

Detailed Description

The technical solution in the embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings, which are simplified schematic drawings and only schematically illustrate the basic structure of the present invention.

According to fig. 1, the utility model discloses a support 4, support 4 be a U type board of bending, two edges of bending of support 4 all opened a Z type hole groove, the Z type hole groove projection on two edges of bending be the coincidence completely, support 4 and dog 5 be connected through round pin axle 1, retaining ring 3 and split pin 2, dog 5 be an L type thick plate, dog 5 upper end be provided with the through-hole, the bottom is provided with a wedge type face, the through-hole with round pin axle 1 phase-match, dog 5 is arranged in the U type opening of support 4, retaining ring 3 be a ring shape sheet metal, retaining ring 3 cup joint in round pin axle 1 both ends, retaining ring 3 respectively with support 4 to the outside laminating of the bend edge of fifty percent discount, round pin axle 1 in the retaining ring 3 outside be provided with split pin 2; the bottom end of a U-shaped bending plate of the support 4 is fixed on the roller frame 6, the pin shaft 1 drives the stop block 5 to be positioned in a downward inclined hole at the upper end of the Z-shaped groove, and the stop block 5 is fixed on the pin shaft under the action of self weight of the stop block, so that the advance of the roller is not influenced.

The utility model discloses from the unclamping state of figure 1 to the locking state overall process of figure 2 as follows: will be connected with round pin axle 1, dog 5 of retaining ring 3 and split pin 2 moves the lower extreme in Z type hole groove along the upper end in 4Z type hole grooves of support, the width in Z type groove lower extreme groove is far greater than round pin axle 1, dog 5 directly places on track 7, dog 5 moves the lower extreme in Z type hole groove through the action of gravity, and not with 4 fixed contact of support, when the gyro wheel has the trend of advancing (support 4 also has the trend of advancing), support 4 does not produce the effort to dog 5 in the direction of advancing, make dog 5 static on track 7, the gyro wheel produces the extrusion with dog 5, hinder the trend of advancing of gyro wheel.

The overall dimension of the retainer ring 3 is far larger than the width of the groove at the lower end of the Z-shaped groove, so that when the stop dog 5 in fig. 2 is still placed on the track 7, the normal tilting tendency of the stop dog 5 in the advancing direction of the track 7 is blocked under the matching of the retainer rings 3 at the two sides and the support 4.

The utility model has simple and reliable structure, simple and rapid operation, and can rapidly and effectively carry out production, thereby effectively improving the production efficiency; the utility model discloses a track locking device, low in manufacturing cost is honest and clean, can effectually save manufacturing cost.
