Description

Technical Field

[0001] The invention relates to the technical field of brake devices, and in particular to a hydraulic brake device with a cavity heat dissipation structure. Background Art

[0002] The brake system generates friction between the brake pads and the wheel drum or disc, and in the process of friction, the kinetic energy of the car when it is moving is converted into heat energy and consumed. Common brake systems include "drum brakes" and "disc brakes".

[0003] The brake system of oil drilling rigs and workover rigs mainly uses disc brake systems to achieve the braking effect. Through the friction between the caliper and the brake disc in the brake structure, the kinetic energy is converted into heat energy for consumption, and the equipment is gradually stopped under the action of friction braking. The heat generated by friction is extremely high. If this heat cannot be dissipated in time, it will lead to a decline in braking performance and even cause safety accidents. Overheating of the brake structure will cause changes in its material properties, and the strength and high temperature resistance will be reduced. In severe cases, it may cause the brake pads to decompose, thus affecting the braking effect.

[0004] In the prior art, more and more technical solutions for brake structures have emerged, such as the use of ceramic brake structures or carbon fiber brake structures, or the opening of cavities in the brake discs to make water channels for heat dissipation and cooling. The front-end will lead to an increase in the cost of a single brake structure and a high cost of use. The latter has high requirements on the process level and cannot be applied to conventional brake devices. At the same time, when the existing hydraulic brake devices are braking, the brake structure at one end of the piston rod will contact the brake disc in advance, and then the other side will be pushed close to the brake disc, causing the brake structure at one end of the piston rod to be more severely worn, and there is room for improvement in the smoothness of braking. Therefore, there is an urgent need for a brake device with a large heat dissipation area, good braking effect, simple structure and easy matching to solve the above problems.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 7The present invention provides a technical solution: a hydraulic brake device with a cavity heat dissipation structure, comprising two fixed shafts 1 and a hydraulic cylinder 2, two moving blocks 3 are hinged between the opposite sides of the two fixed shafts 1 through a pin shaft, the top of the moving block 3 is provided with an opening groove 4 with openings on both the left and right sides, the piston rod end of the hydraulic cylinder 2 and the end away from the piston rod are fixedly installed with an articulation block 5, a positioning pin shaft 6 is passed through and installed between the front of the moving block 3 and the corresponding front of the articulation block 5, two mounting rods 21 are passed through and detachably connected on the left sides of the two positioning pin shafts 6, and a tension spring 22 is detachably connected between the opposite ends of the two mounting rods 21, a brake assembly 700 and a guide stabilization assembly 800 are installed between the opposite sides of the two moving blocks 3, and a fine-tuning assembly 900 is installed on the outer side of the brake assembly 700;

[0035] In the above-mentioned embodiment, through the brake assembly 700, the advantages of the cavity can be utilized to increase the total amount of flowing air, and the contact area with the brake structure can also be increased. The actual increased heat dissipation area is more than three times the area where the heat is concentrated, so that the heat generated by braking can be discharged more efficiently. Through the guide stabilization assembly 800, the brake structures on both sides can move synchronously, and while the single hydraulic transmission structure is driven, the simultaneity of the pressure braking on both sides of the brake disc is ensured, which effectively improves the smoothness of braking, makes the wear conditions of the brake structures on both sides similar, and limits the clamping direction by means of a limit guide, so that the brake structure can move parallel to the brake disc, so that the friction braking force can respond more quickly, and through the fine-tuning assembly 900, the position of the brake structure can be appropriately adjusted after a certain wear, so that the worn part can be compensated, so that it can maintain a good brake response state before replacement.

[0036] It should be noted that the outer side of the articulated block 5 is hinged to the top of the outer side of the corresponding movable block 3 through the positioning pin shaft 6, and the front and back sides of the articulated block 5 are respectively fitted with the front and back inner walls of the corresponding opening groove 4, and the fitting surfaces are smooth, so that the articulated block 5 can rotate relative to the corresponding movable block 3.

[0037] In this embodiment, the brake assembly 700 is a structure used to squeeze the brake disc to brake it and increase the heat dissipation area.

[0038] like Figure 1 and Figure 4As shown, the brake assembly 700 includes four connecting blocks 701 which are respectively hinged to the front and back sides of the bottom of the two moving blocks 3 through pins, and the opposite sides of the left and right connecting blocks 701 are abutted with heat dissipation blocks 702, and the opposite sides of the two heat dissipation blocks 702 are detachably connected with the brake pad body 703, and the interior of the brake pad body 703 is provided with a heat dissipation cavity 704 which is opened on the front and back sides, and a plurality of support blocks 705 are fixed between the left and right inner walls of the heat dissipation cavity 704.

[0039] It should be noted that the two heat dissipation blocks 702 are respectively abutted against two connecting blocks 701 on their opposite sides, so that the heat dissipation blocks 702 can be driven and pushed by the corresponding two connecting blocks 701, and the support blocks 705 inside each heat dissipation cavity 704 are divided into two groups, upper and lower, and each group of support blocks 705 are arranged at equal distances, so that the support blocks 705 can support the heat dissipation cavity 704 without excessively hindering the circulation of air.

[0040] In this embodiment, the guide stabilization assembly 800 is a structure used to guide the transmission direction and enable the brake pad body 703 to move in a parallel posture.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the guiding and stabilizing assembly 800 includes a mounting plate 801 detachably connected to the front and back sides of the moving block 3, an extension plate 802 is fixed to the side of the mounting plate 801 away from the corresponding moving block 3, a bonding plate 803 is fixed to the side of the extension plate 802 away from the corresponding mounting plate 801, a guide hole 804 is provided on the side of the bonding plate 803 away from the corresponding moving block 3, a guide rod 805 is detachably connected to the side of the connecting block 701 away from the corresponding moving block 3, and a transmission half gear 808 is fixedly installed on the opposite sides of the two moving blocks 3.

[0042] It should be noted that an embedded groove 806 is provided at the end of the guide rod 805 away from the corresponding connecting block 701, and an embedded hexagon socket bolt 807 located on the inner side of the corresponding embedded groove 806 is passed through the end of the guide rod 805 away from the corresponding connecting block 701. An inner thread groove for threaded connection of the corresponding embedded hexagon socket bolt 807 is provided on the side of the connecting block 701 away from the corresponding moving block 3, so that the guide rod 805 can be easily replaced to prevent the guiding function from being affected due to wear on the outer side.

[0043] It can be understood that the side of the bonding plate 803 close to the corresponding connecting block 701 is bonded thereto, and the contact surface is smooth, so that the relative sliding process can be relatively smooth, the guide hole 804 is inclined, and the side close to the corresponding heat dissipation block 702 is a high point, and the guide rod 805 is plugged into and slidably connected to the inner side of the corresponding guide hole 804, so that when the moving block 3 pushes the heat dissipation block 702 to move through the two connecting blocks 701, it can also drive the guide rod 805 to move, and then the guide rod 805 can be gradually lifted upward during the movement of the connecting block 701, so that the connecting block 701 can remain in a relatively parallel state close to the brake disc.

[0044] In addition, the opposite sides of the two transmission half gears 808 are meshed with each other, so that when the piston rod end of the hydraulic cylinder 2 pushes the corresponding hinge block 5 to move, the other side can move synchronously under the meshing transmission action between the two transmission half gears 808, and then the two moving blocks 3 can move in opposite directions at the same time, so that the two brake pad bodies 703 can simultaneously abut against the brake disc to apply pressure to it.

[0045] In this embodiment, the fine-tuning assembly 900 is a structure for fine-tuning the distance between the two brake pad bodies 703 .

[0046] like Figure 5 , Figure 6 and Figure 7 As shown, the fine-tuning assembly 900 includes four indicator plates 901 respectively fixed to opposite sides of two heat dissipation blocks 702, four internal thread grooves 902 are provided on the opposite sides of the two heat dissipation blocks 702, and the inner side of the internal thread grooves 902 is threadedly connected with a coarse threaded rod 903, and two connecting grooves 904 are provided on the opposite sides of the left and right connecting blocks 701, and connecting rods 905 are fixed to the opposite ends of the coarse threaded rods 903 on the left and right sides, and fine threaded rods 906 are fixed to the opposite ends of the left and right connecting rods 905, and the fine threaded rods 906 are provided with a first hexagonal inner groove 904 at one end away from the corresponding connecting rod 905. 7. Two external blocks 908 are fixed on the opposite sides of the left and right connecting blocks 701. A mounting groove 909 is provided on the side of the external block 908 away from the corresponding connecting block 701. A bearing seat 910 is detachably connected to the inner side of the mounting groove 909. An internal thread block 911 and an external hexagonal tube 912 are threadedly connected to the outer side of the fine thread rod 906. An abutment ring 913 is fixed on the side of the internal thread block 911 close to the corresponding bearing seat 910. A second internal hexagonal groove 914 is provided on the side of the external hexagonal tube 912 away from the corresponding bearing seat 910. A shielding cover 915 is detachably connected to the side of the external block 908 away from the corresponding connecting block 701.

[0047] It should be noted that the four indicator plates 901 are respectively fitted with the tops of the four connecting blocks 701. When fine-tuning, it must be ensured that the indicator plate 901 does not exceed the side of the corresponding connecting block 701 close to the heat dissipation block 702, so as to ensure the stability of the connection and the safety of use. The actual length of the indicator plate 901 is determined according to the actual thickness of the brake pad body 703. The inner side of the connecting groove 904 is provided for the corresponding coarse threaded rod 903 to be plugged in, and the inner side of the connecting groove 904 away from the corresponding heat dissipation block 702 can be abutted against the end of the corresponding coarse threaded rod 903, and the contact surface is smooth, so that the coarse threaded rod 903 can enter the interior of the corresponding connecting groove 904, and then when the brake pad body 703 squeezes the brake disc, the extrusion force will be directly transmitted to the corresponding connecting block 701 through the coarse threaded rod 903.

[0048] In addition, one end of the connecting rod 905 away from the corresponding heat sink 702 passes through the side of the corresponding connecting block 701 away from the heat sink 702, the side of the corresponding external block 908 close to the heat sink 702 and the inside of the corresponding mounting groove 909 in sequence. The outer side of the connecting rod 905 is rotatably connected to the inner side of the corresponding bearing seat 910 through a bearing, so that the connecting rod 905 can rotate stably.

[0049] At the same time, the internal thread block 911 and the corresponding external hexagonal tube 912 are fixedly connected to each other on opposite sides, and the abutment ring 913 abuts against the outer side of the corresponding bearing seat 910 away from the side of the corresponding internal thread block 911, so that the abutment ring 913 can play the role of abutment limit, and can achieve the locking function through the threaded connection between the internal thread block 911 and the external hexagonal tube 912 and the fine thread rod 906, wherein the fine thread rod 906 is a thread structure with a pitch less than or equal to two millimeters. Compared with conventional coarse thread, the main structural features of the fine thread include: small pitch, shallow thread shape, large tooth top angle, small tooth bottom angle, and can achieve self-locking effect. The coarse thread rod 903 is a rectangular thread with the characteristics of high strength and high load-bearing capacity, which can meet the needs of pressure abutment. The shielding cover 915 is located on the outside of the corresponding external hexagonal tube 912 and can play a shielding and protective role.

[0050] The working principle of the above embodiment is:

[0051] (1) When in use, the hydraulic cylinder 2 is started so that the piston rod end pushes the corresponding hinge block 5 to move, so that the moving block 3 on the same side rotates under the hinge action of the fixed shaft rod 1, and drives the corresponding transmission half gear 808 to rotate, which can drive the other transmission half gear 808 to move synchronously, and then the side of the hydraulic cylinder 2 away from the piston rod end moves through the corresponding hinge block 5, so that the two moving blocks 3 can move synchronously, and then the corresponding two connecting blocks 701 can be pushed to move at the same time, and the heat dissipation block 702 can be driven to move in the opposite direction under the action of the hinge. During the movement, the two brake pad bodies 703 can move in a relatively parallel posture under the guiding and limiting action between the guide rod 805 and the corresponding guide hole 804, that is, they can contact the brake disc in parallel and stably, and brake through friction, and the friction heat is transmitted to the heat dissipation block 702, and the contact area with the air is increased under the action of the heat dissipation cavity 704, so that the heat generated by braking can be discharged more efficiently.

[0052] (2) After long-term use, the brake pad body 703 will show certain wear and tear. It can be fine-tuned appropriately according to actual conditions. The shielding cover 915 is removed, and the outer hexagonal tube 912 is rotated to disengage it from the outer side of the fine thread rod 906. The fine thread rod 906 is rotated through the first inner hexagonal groove 907, so that the connecting rod 905 drives the coarse thread rod 903 to rotate. The four coarse thread rods 903 on the same side are rotated in turn in a clockwise or counterclockwise direction. The meshing clearance tolerance between the coarse thread rod 903 and the corresponding inner thread groove 902 is utilized to push the heat dissipation block 702 away from the corresponding two connecting blocks 701, so as to adjust the gap between the two brake pad bodies 703 and achieve appropriate compensation. In a short time, the brake response state can be unaffected by the wear of the brake pad body 703. After the adjustment is completed, the reverse operation is performed according to the above principle, and the outer hexagonal tube 912 and the shielding cover 915 are reinstalled in turn to complete the adjustment, so that the brake pad body 703 can continue to be used stably.

[0053] Compared with the prior art, the hydraulic brake device with a cavity heat dissipation structure has the following advantages:

[0054] 1. The hydraulic brake device with a cavity heat dissipation structure can utilize the advantages of the cavity to increase the total amount of flowing air through the brake assembly 700, and can also increase the contact area with the brake structure. The actual increased heat dissipation area is more than three times the area where the heat is concentrated, so that the heat generated by braking can be discharged more efficiently, and the heat dissipation effect is significantly improved. In addition, through the cooperation of the inner support structure, the brake structure can ensure the strength when pressure braking is applied while retaining the cavity heat dissipation form, making it less likely to deform, thereby improving the heat dissipation effect while ensuring the stability and effectiveness of the brake.

[0055] 2. The hydraulic brake device with a cavity heat dissipation structure can make the brake structures on both sides move synchronously through the guide stabilization component 800, so that the single hydraulic transmission structure drives and the simultaneous pressure braking on both sides of the brake disc is ensured, thereby preventing the use of two hydraulic transmission structures to occupy too large an installation area, effectively improving the smoothness of the brake, and making the wear conditions of the brake structures on both sides similar, which is convenient for simultaneous maintenance or replacement, and is beneficial for the user to make judgments and use them stably, and can appropriately shorten the time for full closure, and also limit the clamping direction by means of a limit guide, so that the brake structure can move parallel to the brake disc, so that the initial contact area is the total braking area of ​​the brake structure, so that the friction braking force can respond more quickly, and the braking capacity is further improved.

[0056] 3. The hydraulic brake device with a cavity heat dissipation structure can, through the fine-tuning component 900, appropriately adjust the position of the brake structure after it has been worn to a certain extent, thereby compensating for the worn part and enabling it to maintain a good brake response state before replacement, so that the gap between the brake structure and the brake disc will not be too large. Under the premise of ensuring safety, the stable use time is appropriately improved, a certain use cost is saved, and the problem that if the existing brake structure wants to improve its heat dissipation effect, it needs a large cost to replace the manufacturing material, and it is inconvenient to match with conventional brake devices is solved.
