DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 1-2 As shown, the utility model provides an automatic parking device for a rail locomotive, comprising: a gate seat 3 arranged on the outer side of the wheel, a mounting compartment 16 is provided on the side of the gate seat 3 close to the wheel, a retractable brake shoe 2 is installed in the installation, a driving block 13 is movably installed on one side of the gate seat 3, one end of the driving block 13 can be inserted between the gate seat 3 and the brake shoe 2, and the driving block 13 is used to drive the brake shoe 2 to extend out of the gate seat 3 or retract into the gate seat 3.

[0023] Combination Figure 2-3 As shown, the driving block 13 is a rectangular columnar structure, and a slope 12 is provided at the bottom of the driving block 13 near one end of the brake shoe 2 , and one end of the slope 12 extends to between the gate seat 3 and the brake shoe 2 .

[0024] As mentioned above, when using the gate seat 3, brake shoe 2 and driving block 13 provided by the utility model, the gate seat 3 is arranged on the outer side of the wheel, the brake shoe 2 is telescopically installed on the gate seat 3 through the mounting chamber 16, and one end of the driving block 13 is inserted between the brake shoe 2 and the gate seat 3. When the driving block 13 is pushed inward, the brake shoe 2 is pushed outward from the mounting chamber 16 through the inclined surface 12 on the driving block 13, so that the brake shoe 2 abuts against the wheel. At this time, the wheel is parked through the brake shoe 2. When the driving block 13 is pulled outward, the driving block 13 does not apply an outward thrust to the brake shoe 2, thereby releasing the restriction of the brake shoe 2 on the wheel.

[0025] In the present utility model, combined with Figure 2 As shown, a detachable mounting seat 6 is also installed on one side of the gate seat 3 of the present embodiment, and a rectangular groove 7 is provided on the mounting seat 6 along the moving direction of the driving block 13. The driving block 13 is movably installed in the rectangular groove 7, and a screw 8 is rotatably installed on the end of the mounting seat 6 away from the gate seat 3. A threaded hole 9 for accommodating the screw 8 is provided on the driving block 13, and a motor 1 connected to the screw 8 is provided on the outside of the mounting seat 6.

[0026] As mentioned above, when using the mounting seat 6 provided by the utility model, a mounting position is provided for the driving block 13 on one side of the gate seat 3 through the mounting seat 6, the screw 8 can be driven to rotate by the motor 1, and the driving block 13 is allowed to reciprocate in the rectangular groove 7 with the cooperation of the threaded hole 9. When the driving block 13 enters the gate seat 3, the driving block 13 is inserted between the gate seat 3 and the brake shoe 2, thereby pushing the brake shoe 2 outward. When the driving block 13 moves to the side away from the gate seat 3, the driving block 13 is disengaged from the abutment on the brake shoe 2, thereby releasing the clamping of the brake shoe 2 on the wheel.

[0027] Further, in order to allow the mounting seat 6 to be detachably mounted on the gate seat 3, refer to Figure 2 and Figure 4 As shown, an external thread seat 11 is also installed on the outer wall of the gate seat 3, a retaining ring 10 is provided on the outer side of the mounting seat 6 near one end of the gate seat 3, and a thread sleeve 5 is provided on the outer side of the mounting seat 6, which is screwed on the external thread seat 11, and the retaining ring 10 is arranged between the external thread seat 11 and the thread sleeve 5. The thread sleeve 5 is sleeved on the mounting seat 6, and the retaining ring 10 on the mounting seat 6 is aligned with the external thread seat 11, and the thread sleeve 5 is screwed on the external thread seat 11. At this time, the retaining ring 10 is clamped between the external thread seat 11 and the thread sleeve 5. At this time, the mounting seat 6 is detachably mounted on the external thread seat 11, and the driving block 13 can be replaced by reversing the above steps.

[0028] In the present utility model, combined with Figure 2 As shown, the installation bin 16 of this embodiment is also equipped with a spring 14 for driving the brake shoe 2 to automatically retract. A first installation hole 15 for accommodating one end of the spring 14 is provided at one end of the brake shoe 2 close to the gate seat 3, and the other end of the spring 14 can be detachably installed on the inner wall of the installation bin 16.

[0029] Combination Figure 2 As shown, a second mounting hole 17 for accommodating the top of the spring 14 is also opened on the top of the mounting compartment 16, a limiting pin 4 is installed on the outside of the gate seat 3 and passes through the second mounting hole 17 horizontally, and a mounting ring is provided on the top of the spring 14 and is sleeved on the limiting pin 4.

[0030] As mentioned above, when using the spring 14 provided by the utility model, the spring 14 is installed on the brake shoe 2 through the first mounting hole 15, one end of the brake shoe 2 is inserted into the gate seat 3 through the mounting chamber 16, and the brake shoe 2 is allowed to enter the mounting chamber 16 as a whole. At this time, the top end of the spring 14 is in the second mounting hole 17, and the limit pin 4 is inserted into the second mounting hole 17 from the outside of the gate seat 3. During this process, the limit pin 4 passes through the mounting ring at the top end of the spring 14, so that the spring 14 is detachably installed in the gate seat 3. The brake shoe 2 can be replaced by reversing the above steps. When the drive block 13 is pulled outward, the spring 14 retracts, thereby driving the pushed out brake shoe 2 to automatically retract into the mounting chamber 16, thereby allowing the brake shoe 2 to detach from the wheel to prevent the brake shoe 2 from interfering with the wheel.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
