[0023] 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.

[0024] Example 1

[0025] Please see Figure 1-6 This embodiment provides the following technical solution: a hydraulic wheel-side brake, including a frame 1, with brake arms 2 rotatably connected to both the left and right ends of the frame 1, a hydraulic cylinder 3 disposed on the upper part of the frame 1, the piston end of the hydraulic cylinder 3 being connected to the upper end of the left brake arm 2 through an adjusting mechanism 7, a fixed seat 4 being fixedly connected to the fixed end of the hydraulic cylinder 3, the fixed seat 4 being hinged to the upper end of the right brake arm 2, a brake frame 5 being rotatably connected to the lower end of the brake arm 2, and brake pads 6 being disposed on the opposite side of the two brake frames 5.

[0026] It also includes an adjustment mechanism 7 for adjusting the gap between the brake pad 6 and the brake disc. The adjustment mechanism 7 includes an adjustment block 71 and an adjustment screw 72. The adjustment block 71 is rotatably connected to the brake arm 2 by a pin. The right end of the adjustment screw 72 is fixedly connected to the piston end of the cylinder 3. The left end of the adjustment screw 72 passes through the through groove provided on the adjustment block 71 and is threaded with a locking nut 73. An adjustment nut 74 is threaded on the adjustment screw 72 on the other side of the adjustment block 71. The adjustment nut 74 is positioned opposite the cylinder 3. The locking nut 73 is positioned on the other side of the adjustment block 71.

[0027] When the gap increases, loosen the locking nut 73 to separate it from the surface of the adjusting block 71; rotate the adjusting nut 74 clockwise to push the adjusting block 71 to swing around the pin axis of the brake arm 2 towards the brake disc, and the adjusting block 71 will squeeze the back of the brake pad 6 to reduce the gap between the pad and the brake disc; after the gap is adjusted to the preset value, tighten the locking nut 73 counterclockwise until it is close to the surface of the adjusting block 71 to lock the adjustment position;

[0028] When the gap decreases, loosen the locking nut 73 and rotate the adjusting nut 74 counterclockwise. The adjusting block 71 swings in the opposite direction under the reaction force of the brake pad 6 or its own weight, increasing the gap between the pad and the brake disc. After adjustment, tighten the locking nut 73.

[0029] The brake frame 5 includes a rotating shaft 51 and a rotating plate 52. The rotating shaft 51 is mounted through the brake arm 2 and rotatably connected to the brake arm 2. Rotating plates 52 are fixedly connected to the front and rear sides of the brake arm 2 on the rotating shaft 51. The rotating plates 52 on the front and rear sides are fixedly connected to each other by a mounting plate 53. With the rotating plates 52 and the mounting plate 53, when the brake arm 2 rotates at the hinge point, the rotating plates 52 and the mounting plate 53 can rotate around the rotating shaft 51.

[0030] Example 2

[0031] Please see Figure 3-4 It also includes a positioning mechanism for positioning the brake pad 6 on the mounting plate 53. The positioning mechanism includes positioning blocks 8, and multiple positioning blocks 8 are provided. One end of the positioning block 8 is fixedly connected to the mounting plate 53, and the other end of the positioning block 8 is movably inserted into the positioning groove 9 on the brake pad 6. In some embodiments, two positioning blocks are provided. The two positioning blocks 8 are symmetrically distributed on the front and rear sides of the mounting plate 53 with the brake arm 2 as the center. The positioning blocks 8 have a cross-shaped structure. Through the positioning blocks 8 and the positioning groove 9, the position of the brake pad can be limited, which improves the stability of the brake pad on the mounting plate 53.

[0032] like Figure 5 and Figure 6As shown, both the front and rear ends of the brake pad 6 and the brake frame 5 are connected by a quick-release mechanism 10. The quick-release mechanism 10 includes a card seat 101, a card rod 102, and a card plate 109. The card seat 101 is fixedly connected to the brake pad 6, and the card rod 102 is rotatably connected to the card seat 101. The card plate 109 is fixedly connected to the brake frame 5. The card plate 109 is provided with a card cavity 103 that is adapted to the card rod 102. The card plate 109 is provided with a clamping assembly for locking and fixing the other end of the card rod 102. By using the card seat 101, card rod 102, card plate 109, and clamping assembly, the traditional method of fixing the brake pad 6 with bolts is replaced, which enables quick disassembly and assembly of the brake pad 6, improving the replacement efficiency of the brake pad 6 and the efficiency of equipment maintenance.

[0033] In some embodiments, the lever 102 has an L-shaped structure.

[0034] Both the card holder 101 and the card rod 102 have a pin hole at one end for inserting the pin 104. The pin 104 passes through the card holder 101 and the end of the card rod 102 and is movably inserted with a pin. Through the provided pin hole, the card rod 102 can be easily installed and removed from the card holder 101, and the card rod 102 can be rotated on the card holder 101.

[0035] The clamping assembly includes a drive plate 105, a rod 106, and a socket 107. The drive plate 105 is positioned above the clamping plate 109, and the drive plate 105 and the clamping plate 109 are connected by an elastic element. The rod 106 is fixedly connected to the drive plate 105. The rod 106 is adapted to the socket 107 on the clamping plate 109 and the clamping rod 102. Through the drive plate 105 and the elastic element, the rod 106 can be inserted into the socket 107 on the clamping rod 102 to fix the position of the clamping rod 102, thereby fixing the brake pad. Alternatively, the rod 106 can be disengaged from the socket 107 on the clamping rod 102, allowing the clamping rod 102 to detach from the clamping plate 109 and the brake pad 6 to be removed from the mounting plate 53. Thus, the disassembly and assembly of the brake pad is completed by disassembling and assembling the clamping rod 102.

[0036] In some embodiments, two insertion rods 106 are provided, and the two insertion rods 106 are symmetrically distributed on the drive plate 105.

[0037] The elastic element includes a return spring 108, which is movably sleeved on the outside of the insertion rod 106. Both the upper and lower ends of the return spring 108 are fixedly connected to spring seats. The upper spring seat is fixedly connected to the drive plate 105, and the lower spring seat is fixedly connected to the clamping plate 109. By using the return spring 108, the drive plate 105 and the insertion rod 106 can be reset after the external force on the drive plate 105 is lost, so that the insertion rod 106 can be re-inserted into the insertion hole 107 on the clamping rod 102.

[0038] The working principle of this utility model is as follows: When in use, when the pressure oil in the hydraulic station enters the oil cylinder 3 under the control of the solenoid valve, the pressure generated by the hydraulic oil further compresses the disc spring and at the same time pushes the piston rod to drive the two brake arms 2 to open to the left and right. At this time, the braking torque is eliminated, and the wheel can rotate freely, thus releasing the brake.

[0039] When the solenoid valve is de-energized and reset, the hydraulic oil flows back to the hydraulic station oil tank under the action of the disc spring force. At the same time, the disc spring force is applied to the braked wheel through the piston rod and brake arm 2, so that the brake pad 6 tightly grips the wheel, establishes the specified braking torque, thereby achieving braking and preventing the wheel from rotating.

[0040] When the brake liner needs to be removed, simply pull each drive plate 105 on the mounting plate 53 upwards in sequence to move the insert rod 106 upwards until the lower end of the insert rod 106 disengages from the insertion hole 107 on the latch rod 102. At this time, the latch rod 102 disengages from the locking state of the latch plate 109, and the latch rod 102 can be moved. Then, remove the pin on the latch rod 102 and remove the pin 104 from the latch rod 102, thereby removing the brake liner from the mounting plate 53.

[0041] When installing a new brake liner, align the pin holes on the lever 102 and the seat 101, insert the pin 104 into the lever 102 and the seat 101, and insert the pin into the pin 104. Then, align the positioning groove 9 on the brake liner with the positioning block 8 on the mounting plate 53 until the positioning block 8 is inserted into the positioning groove 9, at which point the brake liner is fitted onto the mounting plate 53. Similarly, drag the drive plate 105 to move the insert rod 106 upward, then drag the other end of the lever 102 to insert the lever 102 into the cavity 103 on the plate 109. Then, release the drive plate 105, and under the elastic action of the return spring 108, insert the insert rod 106 into the insertion hole 107 on the lever 102, thus fixing the lever 102 and the brake liner.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
