Description

Technical Field

[0001] This invention relates to the field of traction machine technology, specifically to a high-temperature resistant and crack-resistant braking friction plate for traction machines with a multi-layer composite structure. Background Technology

[0002] The braking friction plate of the traction machine consists of two semi-circular plates. The two semi-circular plates generate friction by clamping the rotating parts of the traction machine, thereby braking the traction machine. Frequent friction braking can easily cause wear on the friction plate, resulting in a decrease in the pressure of the friction plate on the rotating parts of the traction machine and a reduction in the braking capacity of the friction plate.

[0003] The existing friction plates for traction machines have the following defects:

[0004] Existing technology CN114517816B discloses a traction machine friction plate capable of achieving noise reduction friction. This technology includes an assembly plate, circular grooves, square through grooves, a friction plate, and extension plates. The front side of the assembly plate has two sets of symmetrically arranged circular grooves and two sets of vertically arranged square through grooves. The friction plate is mounted on the front side of the assembly plate, and extension plates are mounted on both outer walls of the assembly plate. Both outer walls of the extension plates have elongated grooves, with one end of each elongated groove fitting against one outer wall of the two sets of circular grooves. Gravity sensors are mounted on the inner walls of both sets of circular grooves, and connecting wires are mounted on the outer walls of the gravity sensors, with one end of each connecting wire penetrating the interior of the two elongated grooves. This invention can monitor the force applied during braking and absorb vibration through the rubber plate to achieve noise reduction. It also provides a replacement reminder when the friction plate is severely damaged, and replacement is convenient.

[0005] The above-mentioned technology does not have the function of compensating for the wear of the friction plate. The friction plate is prone to wear when it is frequently subjected to friction braking, which reduces the pressure of the friction plate on the rotating parts of the traction machine and reduces the braking capacity of the friction plate. Therefore, a high-temperature and crack-resistant traction machine braking friction plate with a multi-layer composite structure that can compensate for the position of the friction plate due to wear is needed to solve this problem. Summary of the Invention

[0006] One objective of this application is to provide a high-temperature resistant and crack-resistant braking friction pad for traction machines with a multi-layer composite structure, which can solve the technical problems mentioned in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer composite structure high-temperature resistant and crack-resistant traction machine braking friction pad, comprising an arc-shaped plate, a movable frame and a block, wherein the movable frame is movably mounted through the front of the arc-shaped plate, the block is movably mounted through the front of the movable frame, and the friction pad body is mounted on the front of the block.

[0008] A frame is mounted on the back of the arc-shaped plate, and the frame is located outside the movable frame. A pushing mechanism is symmetrically arranged through the back of the frame. The pushing mechanism includes two bolts and a round push block. Two bolts are installed through the back of the frame, and one end of the bolt penetrates the inner wall of the back of the frame. A round push block is installed at one end of the bolt.

[0009] Preferably, the block has symmetrical through-holes on its left side.

[0010] Preferably, a bolt is symmetrically installed through the left side of the movable frame, and one end of the bolt is located inside the positioning hole.

[0011] Preferably, a plurality of heat dissipation holes are provided through one side of the friction pad body, and a wear-resistant layer is installed on the front side of the friction pad body.

[0012] Preferably, connecting rings are symmetrically installed on the back of the movable frame, and the connecting rings are located outside the circular push block.

[0013] Preferably, the top and bottom of the movable frame are symmetrically provided with multiple fitting slots.

[0014] Preferably, multiple positioning plates are symmetrically and movably installed through the top and bottom of the frame, and the positioning plates penetrate the inner wall of the frame. Springs are symmetrically installed at the top and bottom of the frame. A connecting plate is installed at one end of the spring, and the bottom of the connecting plate is connected to the top of the positioning plate. A fitting diagonal rod is installed at the bottom of the positioning plate, and the fitting diagonal rod is located inside the fitting groove.

[0015] Preferably, heat insulation cotton is installed on the outside of the frame.

[0016] Preferably, a controller is installed on the top of the frame, temperature sensors are symmetrically installed on the back of the movable frame and are electrically connected to the controller, and a heating rod is installed through the back of the frame and is electrically connected to the controller.

[0017] Preferably, a heat-conducting shell is installed through the back of the movable frame, the interior of the heat-conducting shell is filled with paraffin wax, and a heat-conducting ring is installed on the back of the heat-conducting shell, with the heat-conducting ring located outside the heating rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. When the wear-resistant layer wears down, the present invention rotates the second bolt to drive the round push block forward, the round push block pushes the moving frame forward, and then drives the friction plate body forward to compensate for the wear of the wear-resistant layer, so that the wear-resistant layer can still ensure sufficient braking friction force for the traction machine after being worn.

[0020] 2. During the forward movement of the moving frame of the present invention, the fitting grooves move forward synchronously, thereby causing the fitting angle bars inside the multiple fitting grooves to be squeezed upward. Then, the fitting angle bars move out of one fitting groove. When the subsequent fitting groove moves below the preceding fitting angle bar, the spring applies a pulling force to the connecting plate, and then the connecting plate applies a force towards the moving frame to the positioning plate, thereby causing the fitting angle bars to move downward again and fit into the rear fitting groove. This enables the positioning plate and the fitting angle bars to strengthen the positioning of the moving frame after it moves forward, increase the stability of the moving frame, and prevent the moving frame from being squeezed backward when the friction plate body is subjected to backward pressure.

[0021] 3. In this invention, when the temperature sensor detects that the internal temperature of the frame is lower than the set value, the controller controls the heating rod to convert electrical energy into heat energy. The heating rod first transfers heat to the heat-conducting ring, then the heat-conducting ring transfers heat to the heat-conducting shell, and the heat-conducting shell transfers heat to the moving frame. The paraffin absorbs some of the heat, thereby reducing the speed at which the heat-conducting shell transfers heat to the moving frame, reducing the heating rate of the moving frame, and thus reducing the phenomenon of thermal fatigue cracks caused by excessive temperature changes in the moving frame in a short period of time. In cold weather, this also reduces the probability of cold cracks caused by the material becoming brittle at low temperatures at the weak protrusions of the moving frame's fitting groove and the fitting diagonal bar.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5This invention provides an embodiment of a high-temperature resistant and crack-resistant braking friction pad for a traction machine with a multi-layer composite structure, comprising an arc-shaped plate 1, a movable frame 2, and a block 3. The movable frame 2 is movably mounted through the front of the arc-shaped plate 1, and the block 3 is movably mounted through the front of the movable frame 2. Positioning holes 4 are symmetrically provided through the left side of the block 3. Bolts 5 are symmetrically installed through the left side of the movable frame 2, with one end of each bolt located inside the positioning hole 4. A friction pad body 6 is mounted on the front of the block 3. Multiple heat dissipation holes 7 are provided through one side of the friction pad body 6. A wear-resistant layer 8 is mounted on the front of the friction pad body 6. The arc-shaped plate 1 provides mounting positions for other components of the device, enabling the… Other components of the equipment are installed in designated locations. The wear-resistant layer 8 is made of iron-copper based powder metallurgy friction material. When the wear-resistant layer 8 generates frictional heat, the friction plate body 6 receives the heat from the wear-resistant layer 8. The heat is then dissipated from the outside of the friction plate body 6 or from the heat dissipation holes 7. The bolt 5, inserted into the positioning hole 4, ensures the stability of the connection between the moving frame 2 and the block 3, thus fixing the moving frame 2 and the block 3 together. When the wear-resistant layer 8 wears, the moving frame 2 is moved forward, which in turn moves the block 3 and the friction plate body 6 forward, thereby compensating for the wear of the wear-resistant layer 8 and preventing insufficient braking force on the traction machine due to wear of the wear-resistant layer 8.

[0034] Please see Figure 1 , Figure 3 , Figure 5 and Figure 6 One embodiment of the present invention provides a high-temperature resistant and crack-resistant braking friction plate for a multi-layer composite structure traction mechanism. A frame 9 is mounted on the back of an arc-shaped plate 1, and the frame 9 is located outside a movable frame 2. A pushing mechanism is symmetrically arranged through the back of the frame 9. The pushing mechanism includes two bolts 12 and two circular push blocks 13. Two bolts 12 are installed through the back of the frame 9, with one end of each bolt 12 penetrating the inner wall of the back of the frame 9. A circular push block 13 is mounted on one end of each bolt 12. The back of the movable frame 2 is symmetrically equipped with... There is a connecting ring 14, which is located outside the circular push block 13. When the wear-resistant layer 8 is worn, the circular push block 13 is moved forward by rotating the bolt 12. The circular push block 13 pushes the moving frame 2 forward, which in turn drives the friction plate body 6 forward to compensate for the wear of the wear-resistant layer 8. This ensures that the wear-resistant layer 8 can still provide sufficient braking friction for the traction machine after being worn. The connecting ring 14 is used to connect the circular push block 13 and the moving frame 2, so that the circular push block 13 and the moving frame 2 can be movably connected.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This invention provides an embodiment of a high-temperature resistant and crack-resistant traction machine braking friction pad with a multi-layer composite structure. Multiple fitting grooves 15 are symmetrically provided through the top and bottom of the moving frame 2. Multiple positioning plates 16 are symmetrically and movably installed through the top and bottom of the frame body 9, and the positioning plates 16 penetrate the inner wall of the frame body 9. Springs 18 are symmetrically installed at the top and bottom of the frame body 9. A connecting plate 17 is installed at one end of each spring 18, and the bottom of the connecting plate 17 is connected to the top of the positioning plate 16. A fitting inclined rod 19 is installed at the bottom of the positioning plate 16, and the fitting inclined rod 19 is located inside the fitting groove 15. During the forward movement of the moving frame 2, the fitting groove 15 synchronously moves... The forward movement causes the engagement rods 19 inside the multiple engagement slots 15 to be squeezed upwards. Then, the engagement rods 19 move out of one engagement slot 15. When the rear engagement slot 15 moves below the front engagement rod 19, the spring 18 applies a pulling force to the connecting plate 17. Then, the connecting plate 17 applies a force toward the moving frame 2 to the positioning plate 16, causing the engagement rods 19 to move downwards again and engage in the rear engagement slot 15. This allows the positioning plate 16 and the engagement rods 19 to reinforce the positioning of the moving frame 2 after it moves forward, increasing the stability of the moving frame 2 and preventing the moving frame 2 from being squeezed backwards when the friction plate body 6 is subjected to backward pressure.

[0036] Please see Figure 1 and Figure 3 This invention provides an embodiment of a high-temperature resistant and crack-resistant traction mechanism braking friction pad with a multi-layer composite structure. A heat-insulating cotton 11 is installed on the outer side of the frame 9, a controller 10 is installed on the top of the frame 9, and temperature sensors 20 are symmetrically installed on the back of the moving frame 2, with the temperature sensors 20 electrically connected to the controller 10. A heating rod 24 is installed through the back of the frame 9, and the heating rod 24 is electrically connected to the controller 10. The heat-insulating cotton 11 reduces heat loss inside the frame 9. When the temperature sensor 20 detects that the internal temperature of the frame 9 is lower than a set value, the controller 10 controls the heating rod 24 to convert electrical energy into heat energy, thereby heating the inside of the frame 9, which in turn heats the moving frame 2. The moving frame 2 transfers heat to the interlocking inclined rod 19, thus reducing the probability of cold cracking due to material brittleness at low temperatures at the weak protrusions at the interlocking groove 15 of the moving frame 2 and at the interlocking inclined rod 19 in cold weather.

[0037] Please see Figure 1 , Figure 3 , Figure 5 and Figure 7This invention provides an embodiment of a high-temperature resistant and crack-resistant braking friction pad for a traction mechanism with a multi-layer composite structure. A heat-conducting shell 21 is installed through the back of the moving frame 2. Paraffin wax 22 is installed inside the heat-conducting shell 21. A heat-conducting ring 23 is installed on the back of the heat-conducting shell 21 and is located outside the heating rod 24. The heat-conducting ring 23 is outside the heating rod 24 and contacts the inner wall of the heating rod 24. When the heating rod 24 generates heat, the heating rod 24 first transfers the heat to the heat-conducting ring 23, and then the heat-conducting ring 23 transfers the heat to the heat-conducting shell 21. The heat-conducting shell 21 then transfers the heat to the moving frame 2, and the paraffin wax 22 absorbs some of the heat, thereby reducing the speed at which the heat-conducting shell 21 transfers heat to the moving frame 2, reducing the heating rate of the moving frame 2, and thus reducing the phenomenon of thermal fatigue cracks caused by excessive temperature changes in the moving frame 2 in a short period of time. When the temperature of the moving frame 2 rises to the set value, the heating rod 24 stops heating, and then the paraffin wax 22 slowly transfers heat to the moving frame 2.

[0038] Working Principle: Before using the multi-layer composite high-temperature crack-resistant traction machine braking friction pad, it is necessary to check whether there are any problems affecting its use. When the wear layer 8 wears, rotating bolt 12 drives the circular push block 13 to move forward. The circular push block 13 pushes the moving frame 2 forward, which in turn drives the friction pad body 6 forward to compensate for the wear of the wear layer 8. This ensures that the wear layer 8 can still provide sufficient braking friction for the traction machine after wear. During the forward movement of the moving frame 2, the fitting groove 15 moves forward synchronously, causing the fitting inclined rods 19 inside the multiple fitting grooves 15 to be squeezed upward. Then, the fitting inclined rod 19 moves out of one fitting groove 15. When the subsequent fitting groove 15 moves below the front fitting inclined rod 19, the spring 18 applies a pulling force to the connecting plate 17. Then, the connecting plate 17 applies a force towards the moving frame 2 to the positioning plate 16, thereby causing the fitting inclined rod 19 to move upward again. The moving frame 2 moves downward and fits into the rear fitting groove 15, thereby enabling the positioning plate 16 and the fitting diagonal bar 19 to reinforce the positioning of the moving frame 2 after it moves forward, increasing the stability of the moving frame 2 and preventing the moving frame 2 from being squeezed backward when the friction plate body 6 is subjected to backward pressure. When the temperature sensor 20 detects that the internal temperature of the frame 9 is lower than the set value, the controller 10 controls the heating rod 24 to work and convert electrical energy into heat energy. The heating rod 24 first transfers heat to the heat-conducting ring 23, and then the heat-conducting ring 23 transfers heat to the heat-conducting shell 21. The heat-conducting shell 21 then transfers heat to the moving frame 2, and the paraffin wax 22 absorbs some of the heat, thereby reducing the speed at which the heat-conducting shell 21 transfers heat to the moving frame 2, reducing the heating rate of the moving frame 2, and thus reducing the phenomenon of thermal fatigue cracks caused by excessive temperature changes in the moving frame 2 in a short period of time. When the temperature of the moving frame 2 rises to the set value, the heating rod 24 stops heating, and then the paraffin wax 22 slowly transfers heat to the moving frame 2.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
