DETAILED DESCRIPTION

[0018] 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.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The utility model provides a heavy-load prefabricated beam handling robot braking device, which is mainly used in some mobile conveying robots used to transfer prefabricated beams on site, and the mobile conveying robot can be moved by wheels. Specifically, the braking device of the utility model mainly includes a brake disc 1, a main brake assembly 2 and an auxiliary brake assembly 3 located on the side of the brake disc 1, and the main brake assembly 2 and the auxiliary brake assembly 3 can brake the wheel by controlling the brake disc 1. A fixed shaft (not shown in the figure) is provided on one side of the brake disc 1, and the fixed shaft is located in the middle of the wheel. The main brake assembly 2 is rotatably connected to the fixed shaft to fix the position of the main brake assembly 2, so that the main brake assembly 2 does not rotate with the brake disc 1, so as to use the main brake assembly 2 to rub the brake disc 1 for braking. The main brake assembly 2 can adopt the existing technology; the auxiliary brake assembly 3 is fixedly connected to one side of the main brake assembly 2, and is used to control it to be in a stopped state when the main brake assembly 2 has completed the stop or is about to stop, so as to prevent the main brake assembly 2 from being unstable due to the excessive load of the conveying robot.

[0022] The auxiliary brake device 3 includes a ball screw slide module 4, an auxiliary brake block 5 and an auxiliary brake gear ring 6. The ball screw slide module 4 includes a ball screw, bearing plates located at both ends of the ball screw, a slide rail connected between the two bearing plates, and a slide connected to the ball screw cylinder for relative rotation. The ball screw is driven by a motor, and the motor is preferably a battery-type. The slide is slidably connected to the slide rail. The structure of the ball screw slide module here can be adopted from the existing technology, which will not be repeated here. The ball screw slide module 4 is fixed to the main brake assembly 2 and is distributed parallel to the axial direction of the brake disc 1. The auxiliary brake block is fixedly connected to the slide 7 of the ball screw slide module 4, and the auxiliary brake block 5 is arranged toward the brake disc 1. The outer peripheral side of the brake disc 1 is concave to form a section of annular groove (not shown in the figure), and the auxiliary brake gear ring 6 is embedded in this groove. The outer peripheral side of the auxiliary brake gear ring 6 is provided with a plurality of auxiliary brake teeth 8 in a circumferential array. The ball screw slide module 4 can drive the auxiliary brake block 5 to move in and out of the gap formed between adjacent auxiliary brake teeth 8. Therefore, when the auxiliary brake block 5 moves to be located between two auxiliary brake teeth 8, even if the main brake assembly 2 is unstable, the auxiliary brake block 5 and the auxiliary brake teeth 8 can still prevent the "slipping" phenomenon by limiting each other, thereby preventing accidents.

[0023] The auxiliary brake gear ring 6 is detachably connected to the groove of the brake disc 1 through a connecting pin (not shown in the figure) so that the worn auxiliary brake gear ring 6 can be replaced at any time. Specifically, a connecting groove 9 is provided on the auxiliary brake gear ring 6, and the connecting pin is connected to the brake disc 1 through the connecting groove 9. The connecting groove 9 is distributed along the circumference of the auxiliary brake gear ring 6, and the length of the connecting groove 9 is longer than the diameter of the connecting pin, so that the auxiliary brake gear ring 6 can rotate a certain distance relative to the brake disc 1 to form a free rotation distance. Since the auxiliary brake block 5 has a certain probability of colliding with one of the auxiliary brake teeth 8 during the process of moving between the auxiliary brake teeth 8, the free rotation distance left between the auxiliary brake gear ring 6 and the brake disc 1 can ensure that when the auxiliary brake teeth 8 and the auxiliary brake block 5 collide with each other, the auxiliary brake gear ring 6 rotates a certain distance relative to each other to avoid the collision. The side of the auxiliary brake block 5 opposite to the auxiliary brake gear ring 6 is set to a concave arc structure, so that when the auxiliary brake teeth 8 drive the auxiliary brake gear ring 6 to rotate relative to each other, the auxiliary brake block 5 can smoothly enter between two adjacent auxiliary brake teeth 8 by utilizing the guiding effect of the arc surface structure.

[0024] In order to facilitate the disassembly of the auxiliary brake gear ring 6, the auxiliary brake gear ring 6 is composed of two half gear rings 10 with the same structure and hinged to each other. One end of the two half gear rings 10 is hinged to each other, and the other end is fixed by screws or bolts, which makes the disassembly process of the auxiliary brake gear ring 10 easier.

[0025] As an optimized implementation, the free end of the auxiliary brake tooth 8 is expanded to form a limiting head 11, so that the width of the limiting head 11 is greater than the width of the auxiliary brake tooth 8, so as to effectively prevent the auxiliary brake block 5 from being separated from the auxiliary brake tooth 11. As a further optimized method, a limiting head is also provided at the free end of the auxiliary brake block 5.

[0026] In this embodiment, the main brake assembly 1 includes a caliper 12 with a U-shaped cavity, and the ball screw slide module 4 is fixedly mounted on the caliper 12. The brake disc 1 is located in the U-shaped cavity near the outer edge, and a fixed brake pad 13 is fixedly provided on one side wall of the U-shaped cavity. The fixed brake pad 13 is rotatably connected to the brake disc 1 to prevent the fixed brake pad 13 from causing rotation obstruction to the brake disc 1; a brake oil chamber 14 is built in the other side wall of the U-shaped cavity, and a piston rod is built in the brake oil chamber 14. The free end of the piston rod is arranged toward the brake disc 1, and the end of the piston rod is connected to the main brake pad 15, and the main brake pad 15 is provided with a friction pad 16. The brake oil chamber 14 is connected to a driving device (not shown in the figure) for driving the piston rod through a pipeline 17. For example, the driving device is a driving oil cylinder connected to the brake oil chamber, and the medium in the brake oil chamber is pushed by the inlet and outlet oil pressure of the driving oil cylinder, thereby driving the piston rod. The driving device adopts the existing technology, so the application itself will not be further described.

[0027] The utility model also includes a controller capable of automatically controlling the auxiliary brake assembly, and the controller is electrically connected to the main brake assembly 2 and the auxiliary brake assembly 3, so that after the main brake assembly 2 stops, a signal can be transmitted to the controller, and the controller then controls the motor of the lead screw slide module 3 to start, driving the auxiliary brake block 5 to move in the direction of the auxiliary brake gear ring 6. Of course, as another alternative embodiment, the auxiliary brake assembly 3 can also be controlled manually, and when the main brake assembly 2 stops, the staff manually starts the motor.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
