Description

Technical Field

[0001] The utility model relates to a caliper disc brake and belongs to the technical field of brakes. Background Art

[0002] The electric hydraulic brake using an electric hydraulic pusher is the most widely used product in the field of industrial brakes. Generally speaking, most of the brakes are installed vertically and cannot be directly adapted to the horizontal installation form. The existing horizontally installed brakes are mostly large in size and occupy a large space around the installation position, which is not conducive to the design and layout of the entire transmission mechanism and is not coordinated. The inventor's prior patent (publication number CN205639392U) discloses an electric hydraulic push rod caliper disc brake. Through the "L"-shaped long arm, short arm and connecting rod structure, the electric hydraulic push rod is located on one side of the upper brake arm and the lower brake arm, which can reduce the horizontal size of the brake, thereby reducing the required installation space in the horizontal direction.

[0003] However, the structure adopted in the above solution is relatively complex, and the lengths of the upper brake arm and the lower brake arm are relatively long, resulting in a larger space occupied by the entire brake, which still cannot meet the installation space requirements of some brakes that need to be installed horizontally. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, the utility model provides a caliper disc brake, which can significantly shorten the length of the clamp arm (brake arm), can flexibly arrange the position of the pusher, reduce the space occupied by the brake, and make the brake have good adaptability. The specific technical solution is as follows.

[0005] A caliper disc brake comprises a bracket, a pusher, an upper clamp arm, a lower clamp arm, an upper brake block and a lower brake block, wherein the upper brake block is arranged at one end of the upper clamp arm, and the middle part of the upper clamp arm is hinged to the bracket; the lower brake block is arranged at one end of the lower clamp arm, and the middle part of the lower clamp arm is hinged to the bracket;

[0006] The invention is characterized in that it further comprises: a frame, a brake rod and a lever, wherein the frame is hinged to one end of the lever, the other end of the lever is hinged to one end of the pusher, and the other end of the pusher is hinged to the frame;

[0007] The other end of the upper clamp arm is rotatably provided with an upper pin shaft, and the axial direction of the upper pin shaft is perpendicular to the swing plane of the upper clamp arm; the upper pin shaft is fixedly connected or hinged to the frame; a through hole is provided on the upper pin shaft, and the axial direction of the through hole is perpendicular to the axial direction of the upper pin shaft;

[0008] A lower pin is rotatably provided at the other end of the lower clamp arm, and the axial direction of the lower pin is perpendicular to the swing plane of the lower clamp arm;

[0009] The upper end of the brake rod is hinged to the lever, the lower end of the brake rod is connected to the lower pin shaft, and the brake rod passes through the avoidance hole of the frame and the through hole of the upper pin shaft.

[0010] By adopting the above technical solution, the brake can be controlled by the pusher to brake or open (release). When the pusher is extended, the lever rotates upward around the hinge axis between the lever and the frame, and the lever pulls the brake rod. The brake rod rotates the lower clamp arm upward around the hinge axis between the lower clamp arm and the bracket through the lower pin shaft, so that the lower brake block at one end of the lower clamp arm moves downward away from the brake disc, forming a lower side opening gap. At the same time, the pusher acts on the reverse thrust of the frame, and the upper clamp arm rotates downward around the hinge axis between the upper clamp arm and the bracket through the upper pin shaft, so that the upper brake block at one end of the upper clamp arm moves upward away from the brake disc, forming an upper side opening gap, and the brake opening (release) action is completed. On the contrary, when the pusher is shortened, the upper and lower brake blocks will fit the brake disc to achieve braking.

[0011] Furthermore, the lower end of the brake rod is threadedly connected to the lower pin shaft. With such arrangement, the screwing position of the brake rod and the lower pin shaft can be adjusted according to the wear degree of the friction pair (composed of the upper and lower brake blocks and the brake disc), thereby improving maintenance efficiency.

[0012] Furthermore, a support spring is also included, the bracket is provided with a support, the lower end of the support spring is connected to the support, the upper end of the support spring is connected to the upper clamp arm, and the upper end of the support spring is located between the upper pin shaft and the hinge shaft of the upper clamp arm and the bracket. In a natural state, the pusher, lever, frame, etc. tend to keep the upper brake block away from the brake disc under the action of gravity. By providing a support spring, the deadweight of the pusher, frame, etc. can be balanced and offset to prevent or reduce the phenomenon of eccentric loading.

[0013] Furthermore, the pusher is an electric hydraulic pusher, an electric pusher, an electromagnetic pusher, a pneumatic cylinder or a hydraulic cylinder, all of which have the function of pushing out (extending) when powered on and retracting when powered off. Alternatively, the pusher is a pusher that pushes out when powered on in the forward direction and retracts when powered on in the reverse direction.

[0014] Furthermore, a brake spring is also included, and the brake spring is arranged inside the pusher; the brake spring is a compression spring, and the pusher has a push rod, and the brake spring is sleeved on the push rod, and one end of the brake spring abuts against the push rod, and the other end abuts against the main body of the pusher. When the pusher is powered on, the pusher extends (the push rod extends), the brake spring is compressed and stores energy, and the brake is opened; when the pusher loses power, the brake spring extends, the pusher shortens (the push rod retracts), and the brake is braked.

[0015] Furthermore, it also includes a brake spring, a first connecting rod, and a second connecting rod. The first connecting rod and the second connecting rod are sleeved with each other, the upper end of the first connecting rod is hinged with the lever, and the lower end of the second connecting rod is hinged with the frame; the brake spring is a compression spring, the brake spring is sleeved on the first connecting rod and / or the second connecting rod, and the two ends of the brake spring are respectively abutted against the first connecting rod and the second connecting rod. When the pusher is powered on, the pusher extends, the brake spring is compressed and stored, and the brake is opened; when the pusher loses power, the brake spring extends, the pusher shortens, and the brake is braked.

[0016] Furthermore, a brake spring is included, which is a compression spring and is arranged between the upper clamp arm and the lower clamp arm. When the pusher is powered on, the pusher is extended, the brake spring is compressed and stores energy, and the brake is opened; when the pusher is powered off, the brake spring is extended, the pusher is shortened, and the brake is braked.

[0017] Furthermore, a brake spring is included, the brake spring is a compression spring, a spring seat is provided on the brake rod, and the brake spring is provided between the spring seat and the frame. When the pusher is powered on, the pusher is extended, the brake spring is compressed and stores energy, and the brake is opened; when the pusher is powered off, the brake spring is extended, the pusher is shortened, and the brake is braked.

[0018] Furthermore, a positioning plate is provided on the bracket, and the upper clamp arm is threadedly connected to a limit screw corresponding to the positioning plate, and the lower clamp arm is threadedly connected to a limit screw corresponding to the positioning plate. When the brake is opened, the upper and lower limit screws are respectively in contact with the positioning plate to limit the maximum swing amplitude of the upper and lower clamp arms to control the brake opening gap. By adjusting the upper and lower limit screws, the purpose of making the opening gap between the two brake blocks and the brake disc equal can also be achieved.

[0019] Furthermore, the upper clamp arm is provided with a first linkage member facing downward, and the lower clamp arm is provided with a second linkage member facing upward, and the first linkage member and the second linkage member are linked to each other through a slide slot and slider mechanism. By providing the first linkage member and the second linkage member, the upper clamp arm and the lower clamp arm can be synchronously expanded outward or retracted inward, and the opening gap between the two brake blocks and the brake disc is approximately equal.

[0020] Furthermore, it also includes a third connecting rod, a fourth connecting rod, a fifth connecting rod and a sixth connecting rod; one end of the third connecting rod is hinged to the bracket, and the other end is hinged to one end of the fourth connecting rod; the other end of the fourth connecting rod is hinged to the upper clamp arm; the bracket, the third connecting rod, the fourth connecting rod and the upper clamp arm form a parallelogram structure; the upper brake block is fixedly connected to the fourth connecting rod; one end of the fifth connecting rod is hinged to the bracket, and the other end is hinged to one end of the sixth connecting rod; the other end of the sixth connecting rod is hinged to the lower clamp arm; the bracket, the fifth connecting rod, the sixth connecting rod and the lower clamp arm form a parallelogram structure; the lower brake block is fixedly connected to the sixth connecting rod. By setting the parallelogram structure, during the opening and closing process of the brake, the upper brake block and the lower brake block will only move parallel to the brake disc and will not swing, so that the upper brake block and the lower brake block can be prevented from being deflected and causing eccentric wear or dragging.

[0021] The brake of the utility model has the characteristics of small product size and flexible installation direction, and can adapt to the equipment installation space more flexibly, especially for equipment with compact installation space. The drive assembly including the pusher can flexibly select the appropriate installation direction, and is also conducive to arranging the adjustment point of the brake in a direction that is convenient for personnel to operate in a small installation space, thereby improving the usability and operability of the equipment. The product structure is simple, and the adjustment operation is intuitive and simple. The setting method of the brake spring is also flexible and adaptable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The utility model is described in further detail below in conjunction with the accompanying drawings.

[0036] Example 1

[0037] See also Figure 1 A caliper disc brake comprises a bracket 1.1, an upper clamp arm 1.2, a lower clamp arm 1.5, an upper brake block 1.3, a lower brake block 1.7, a frame 2.1, a brake rod 2.2, a lever 2.3 and a pusher 2.4, the upper brake block 1.3 is arranged at one end of the upper clamp arm 1.2, and the middle part of the upper clamp arm 1.2 is hinged to the bracket 1.1; the lower brake block 1.7 is arranged at one end of the lower clamp arm 1.5, and the middle part of the lower clamp arm 1.5 is hinged to the bracket 1.1; the upper brake block 1.3 and the lower brake block 1.7 are located on both sides of the brake disc 3;

[0038] The frame 2.1 is hinged to one end of the lever 2.3, the other end of the lever 2.3 is hinged to one end of the pusher 2.4, and the other end of the pusher 2.4 is hinged to the frame 2.1;

[0039] The other end of the upper clamp arm 1.2 is rotatably provided with an upper pin shaft 1.4, the axial direction of which is perpendicular to the swing plane of the upper clamp arm 1.2; the upper pin shaft 1.4 is fixedly connected or hinged to the frame 2.1; a through hole 1.4.1 is provided on the upper pin shaft 1.4, the axial direction of which is perpendicular to the axial direction of the upper pin shaft 1.4;

[0040] The other end of the lower clamp arm 1.5 is rotatably provided with a lower pin shaft 1.6, and the axial direction of the lower pin shaft 1.6 is perpendicular to the swing plane of the lower clamp arm 1.5;

[0041] The upper end of the brake rod 2.2 is hinged to the lever 2.3, and the lower end of the brake rod 2.2 is connected to the lower pin 1.6. The brake rod 2.2 has an avoidance hole 2.1.1 that passes through the frame 2.1 and the through hole 1.4.1 of the upper pin 1.4. The avoidance hole 2.1.1 is to prevent the brake rod 2.2 from interfering with the frame 2.1.

[0042] Preferably, the lower end of the brake rod 2.2 is threadedly connected to the lower pin 1.6. With this arrangement, the screwing position of the brake rod 2.2 and the lower pin 1.6 can be adjusted according to the wear degree of the friction pair (composed of the upper and lower brake blocks 1.7 and the brake disc), thereby improving maintenance efficiency.

[0043] The pusher 2.4 is an electric hydraulic pusher, an electric pusher, an electromagnetic pusher, a pneumatic cylinder or a hydraulic cylinder; all of which have the function of pushing out (extending) when powered on and retracting when powered off. Alternatively, the pusher 2.4 is a pusher that pushes out when powered on in the forward direction and retracts when powered on in the reverse direction. The pusher 2.4 can use an electric hydraulic push rod as described in the Chinese utility model patent with announcement number CN205639392U, or a driving component as described in the Chinese utility model patent with announcement number CN214788700U.

[0044] Among them, the bracket 1.1 is fixedly connected to the main body of the equipment (such as port lifting equipment), and the positions of the bracket 1.1 and the brake disc 3 are relatively fixed; the structural form of the frame 2.1 is not limited, as long as it can achieve the connection relationship with other components such as the pusher 2.4 and the lever 2.3. The frame 2.1 can move relative to the bracket 1.1, that is, the positional relationship between the two can be relatively changed within a certain range. The middle part of the upper clamp arm 1.2 (lower clamp arm 1.5) can be interpreted as a part between the two ends, rather than the midpoint.

[0045] By adopting the above technical solution, the brake can be controlled by the pusher 2.4. When the pusher 2.4 is extended, the lever 2.3 rotates upward around the hinge axis between the lever 2.3 and the frame 2.1, and the lever 2.3 pulls the brake lever 2.2. The brake lever 2.2 rotates the lower clamp arm 1.5 upward around the hinge axis between the lower clamp arm 1.5 and the bracket 1.1 through the lower pin 1.6, so that the lower brake block 1.7 at one end of the lower clamp arm 1.5 moves downward away from the brake disc, forming a lower side opening gap. At the same time, the pusher 2.4 acts on the frame 2.1 with a reverse thrust, and the upper clamp arm 1.2 rotates downward around the hinge axis between the upper clamp arm 1.2 and the bracket 1.1 through the upper pin 1.4, so that the upper brake block 1.3 at one end of the upper clamp arm 1.2 moves upward away from the brake disc, forming an upper side opening gap, and the brake opening (releasing) action is completed. On the contrary, when the pusher 2.4 is shortened, the upper and lower brake blocks 1.7 will fit the brake disc to achieve braking.

[0046] Among them, the bracket 1.1, the upper clamp arm 1.2, the upper brake block 1.3, the upper pin shaft 1.4, the lower clamp arm 1.5, the lower pin shaft 1.6 and the lower brake block 1.7 constitute the clamp assembly 1, and the frame 2.1, the brake rod 2.2, the lever 2.3, the pusher 2.4 and other components constitute the drive assembly 2. Figure 2 As shown, when the clamp assembly 1 and the drive assembly 2 are assembled, the drive assembly 2 can be installed in the radial direction of the clamp assembly 1 relative to the brake disc to reduce the size of the left and right sides of the brake. Figure 3 As shown, when the clamp assembly 1 and the drive assembly 2 are assembled, the drive assembly 2 can also be installed on the left side of the clamp assembly 1 (relative to the left side in the radial direction of the brake disc) to reduce the radial size of the brake assembly relative to the brake disc and reduce the size on the right side. Figure 4 As shown, when the clamp assembly 1 and the drive assembly 2 are assembled, the drive assembly 2 can also be installed on the right side of the clamp assembly 1 (the right side relative to the radial direction of the brake disc) to reduce the radial size of the brake assembly relative to the brake disc, while reducing the size on the left side. The brake of the utility model has the characteristics of small product size and flexible installation direction. It can adapt to the equipment installation space more flexibly, and is particularly suitable for equipment with compact installation space. The drive assembly including the pusher can flexibly select the appropriate installation direction, and is also conducive to arranging the adjustment point of the brake in a direction that is convenient for personnel to operate in a narrow installation space, thereby improving the usability and operability of the equipment.

In a natural state, the pusher 2.4, the lever 2.3, the frame 2.1, etc. tend to keep the upper brake block 1.3 away from the brake disc under the action of gravity. By providing the support spring 4, the deadweight of the pusher 2.4, the frame 2.1, etc. can be balanced and offset, thereby preventing or reducing the phenomenon of eccentric loading.
