Description

Technical Field

[0001] This utility model relates to a disc brake for detecting braking torque and brake disc thickness on a crane. Background Technology

[0002] Disc brakes are crucial for the safe operation of cranes. However, real-time monitoring of brake pressure and brake disc thickness is essential for assessing or predicting the safety and reliability of the brakes.

[0003] Testing the braking torque and disc thickness of crane disc brakes is crucial, as sufficient braking torque is a key factor in ensuring the safe and reliable operation of the crane. Insufficient braking torque can lead to falling objects from the crane, causing significant economic losses. Furthermore, reduced disc thickness affects braking performance and may even result in brake failure. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to accurately monitor braking torque and brake disc thickness, and to provide a new type of disc brake for cranes to detect braking torque and brake disc thickness.

[0005] To solve the above problems, this utility model is achieved through the following technical solution:

[0006] A disc brake for detecting braking torque and disc thickness on a crane includes a base, a brake disc mounted on the base, brake blocks on both sides of the brake disc, and a drive mechanism connected to each brake block. The drive mechanism comprises: a drive frame hinged to each brake block; the lower end of the drive frame is mounted on the base via a hinged seat; a connecting member is hinged to the upper end of the drive frame; a balance bar is hinged to the other end of the connecting member; a connecting rod is hinged to the center of the balance bar; the connecting rod is connected to the output shaft of a hydraulic cylinder; a supporting balance beam is also connected to the output shaft of the hydraulic cylinder; movable covers are connected to both ends of the supporting balance beam; the movable covers are slidably connected to a fixed seat at the bottom; and a pointer scale is mounted on the fixed seat.

[0007] A laser sensor is installed on the drive frame, located on the side of the drive frame facing the brake disc. The laser sensor is used to detect the thickness of the brake disc.

[0008] The drive frame includes two longitudinal drive plates, with at least one crossbar between the two longitudinal drive plates. The top crossbar is connected to a connector. A tension sensor is installed between the connector and the top crossbar.

[0009] The lower end of the drive frame is hinged to the hinge seat via a hinge shaft, and the hinge seat is mounted on the base.

[0010] The mounting bracket is also mounted on the base via a hinged bracket.

[0011] Compared with the prior art, the present invention has the following advantages: it provides a monitoring device that can detect braking torque and brake disc thickness in real time and accurately. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] like Figure 1 As shown, a disc brake for detecting braking torque and disc thickness on a crane includes a base 1, a brake disc 3 mounted on the base 1, and brake blocks 39 on both sides of the brake disc 3. Each brake block 39 is connected to a drive mechanism. The drive mechanism consists of a drive frame 2 hinged to each brake block 39. The lower end of the drive frame 2 is mounted on the base 1 via a hinge seat 4, meaning the lower end of the drive frame 2 is hinged to the hinge seat 4 via a hinge shaft. The hinge seat 4 is mounted on the base 1. A connecting member 35 is hinged to the upper end of the drive frame 2, and a balance bar 5 is hinged to the other end of the connecting member 35, meaning the two drive frames 2 are connected by the balance bar 5.

[0016] A connecting rod 7 is hinged to the center of the balance bar 5, meaning the balance bar 5 is divided into two sections, and the connecting rod 7 hinges to each section. The connecting rod 7 connects to the hydraulic cylinder output shaft 8 of the hydraulic cylinder 17, and a supporting balance beam 38 is also connected to the hydraulic cylinder output shaft 8. Movable covers 19 are connected to both ends of the supporting balance beam 38, and the movable covers 19 are slidably connected to the lower fixed seat 10. A pointer scale 16 is provided on the fixed seat 10, allowing operators to easily observe the vertical movement distance of the movable covers, thus facilitating the measurement of the extension height of the hydraulic cylinder output shaft 8 and enabling convenient control and preset braking pressure. Even better, the fixed seat 10 is also mounted on the base 1 via a hinged joint, allowing the fixed seat 10 to swing without vertical displacement.

[0017] The drive frame 2 includes two longitudinal drive plates, with at least one crossbar between them. The top crossbar is connected to a connector 35. A tension sensor 32 is located between the connector 35 and the top crossbar. More preferably, a brake block 39 is mounted on any one of the middle crossbars. When the drive frame 2 swings, the brake block moves closer to the brake disc, thereby achieving braking.

[0018] A laser sensor 6 is installed on the drive frame 2. The laser sensor 6 is located on the drive frame 2 facing the brake disc and is used to detect the thickness of the brake disc 3.

[0019] The working principle of this utility model is as follows:

[0020] When braking is required, hydraulic cylinder 17 actuates, and hydraulic cylinder output shaft 8 extends upward. Hydraulic cylinder output shaft 8 drives balance bar 5 to move upward via connecting rod 7. First, the center position of balance bar 5 moves upward, then the two ends of balance bar 5 move upward. The two ends of balance bar 5 pull the tops of drive frame 2 on both sides upward via connecting piece 35. The tops of drive frame 2 move upward, causing the middle of drive frame 2 to move towards the center. In this way, drive frame 2 drives brake block 39 to move towards the center. When brake block 39 touches brake disc 3, braking is completed.

[0021] Braking torque detection: The force applied to the drive frame 2 is measured by the tension sensor 32, and the moving distance of the hydraulic cylinder 17 output force is calculated by the pointer scale 16.

[0022] Brake disc thickness detection: The thickness of the brake disc 3 is detected by laser sensor 6, and the laser sensor 6 transmits the data directly to the PLC.

[0023] The results processing section transmits the outputs of laser sensor 6, tension sensor 32, and pointer scale 16 to the PLC. The PLC calculates the braking torque and brake disc thickness according to a preset algorithm and outputs the results. The preset algorithm used by the PLC is existing technology and is not within the scope of protection of this utility model.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
