Description

Technical Field

[0001] The utility model belongs to the technical field of braking devices, and in particular relates to an anti-falling brake mechanism. Background Art

[0002] For equipment with a moving mechanism, such as equipment with a lifting mechanism, during the lifting process, the lifting mechanism may lose the constraint of the driving force due to a sudden power outage or other failures of the equipment. After losing the constraint of the driving force, the moving part of the mechanism may fall, causing a safety accident and damage to the mechanism.

[0003] Taking the measuring machine as an example, its Z axis is a lifting mechanism, that is, a moving mechanism to be braked. In order to prevent the Z axis from falling, an air-floating anti-falling mechanism is usually provided. The air-floating anti-falling mechanism requires the cylinder to be ventilated so that the air-floating block can realize the locking of the Z axis brake. If the equipment suddenly loses power and causes the cylinder to be cut off or the cylinder itself fails and causes the cylinder to be cut off, the Z axis can be braked due to the presence of the air-floating block to prevent the Z axis from falling. However, due to the friction resistance provided by the air-floating block, it cannot completely prevent the Z axis from falling, and the air-floating block will be damaged by friction due to the anti-falling resistance, thus affecting the reliability of the anti-falling.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Reference Figures 1 to 7 In some embodiments of the present application, a fall prevention brake mechanism is proposed, including a cylinder 10, a slider 20, an elastic reset component 30 and a fixed support 40.

[0035] The slider 20 is integrally connected with the cylinder rod 11 of the cylinder 10, so that the slider 20 can be driven to move linearly synchronously when the cylinder 10 is ventilated to extend or retract the cylinder rod 11. That is, when the cylinder 10 is ventilated to extend the cylinder rod 11, the slider 20 is driven to extend synchronously, or when the cylinder 10 is ventilated to retract the cylinder rod 11, the slider 20 is driven to retract synchronously.

[0036] The elastic reset component 30 is elastically deformed as the cylinder rod 11 extends or retracts, so as to drive the cylinder rod 11 to reset when the cylinder 10 is de-energized, thereby driving the slider 20 to reset. That is, if the cylinder 10 is ventilated to extend the cylinder rod 11 and drive the slider 20 to extend synchronously, the elastic reset component 30 can be elastically deformed, such as stretched or compressed; or if the cylinder 10 is ventilated to retract the cylinder rod 11 and drive the slider 20 to retract synchronously, the elastic reset component 30 can be elastically deformed, such as stretched or compressed. The elastic force accumulated by the elastic deformation of the elastic reset component 30 drives the cylinder rod 11 to reset when the cylinder 10 is de-energized, and synchronously drives the slider 20 to reset.

[0037] Two brake links 50 are symmetrically rotatably connected on the fixed support 40, and the brake links 50 are rotatably connected to the slider 20. When the slider 20 moves linearly, it drives the two brake links 50 to realize opening and closing actions; a brake component 60 is provided at one end of the brake link 50, and the brake components 60 of the two brake links 50 are arranged opposite to each other.

[0038] In some embodiments of the present application, the elastic reset component 30 is clamped between the slider 20 and the cylinder body 12 of the cylinder 10. When the cylinder 10 is ventilated, the cylinder rod 11 retracts and synchronously drives the slider 20 to retract and move, and the elastic reset component 30 is compressed during the retraction of the slider 20.

[0039] Specifically, the extended end of the cylinder rod 11 is coaxially fixedly connected with the extension rod 70, the elastic reset component 30 is a spring sleeved on the extension rod 70, the slider 20 is fastened to the free end of the extension rod 70 by screws, and the elastic reset component 30 is sandwiched between the slider 20 and the cylinder body 12 of the cylinder 10. This structure can realize the connection between the slider 20 and the cylinder rod 11, and can also facilitate the installation of the elastic reset component 30, which is conducive to simplifying the overall structure.

[0040] Of course, if Figure 3 and Figure 5 As shown, the elastic reset component can also be arranged between the piston 14 and the cylinder body bottom plate of the cylinder. Similarly, when the cylinder is ventilated, the cylinder rod retracts and the synchronous belt retracts and the slider retracts and moves, and the elastic reset component is compressed during the retracting movement of the slider. Specifically, as Figure 3 and Figure 5 As shown, a cylinder rod 11 may also be provided at the bottom of the piston 14, and the elastic reset component may also be a spring sleeved on the cylinder rod.

[0041] Alternatively, an elastic reset component 30 may be provided between the slider 20 and the cylinder body 12 of the cylinder 10, and between the cylinder piston 14 and the cylinder body bottom plate of the cylinder, so as to increase the elastic force, thereby increasing the braking force of the brake connecting rod on the braking motion mechanism. Figure 7The two brake connecting rods 50 of the anti-fall brake mechanism are in the open and released state as the initial state. At this time, the cylinder 10 is in the ventilated state, and the cylinder rod 11 retracts downward under the action of air pressure to Figure 7 In the state shown, the slider 20 is pulled by the cylinder rod 11 to retract synchronously, that is, it moves linearly toward the direction close to the cylinder 10. Figure 7 In the state shown, the elastic reset component 30 is compressed during the movement of the slider 20, and the movement of the slider 20 drives the two brake connecting rods 50 to open, so that the two brake components 60 move in opposite directions. At this time, the two brake connecting rods 50 are in an open and released state, releasing the braked motion mechanism, such as Figure 7 When the cylinder 10 is out of gas, the cylinder rod 11 is no longer subject to gas pressure. At this time, the elastic force of the elastic reset component 30 drives the cylinder rod 11 to extend, and the slider 20 is pushed upward by the elastic reset component 30 to extend to Figure 1 , Figure 2 , Figure 5 The state shown is a linear movement away from the cylinder 10, whereby the two brake connecting rods 50 are brought close together, so that the two brake components 60 move relative to each other and the distance between them decreases, thereby achieving friction braking of the braked moving mechanism.

[0042] The anti-fall brake mechanism in the embodiment of the present application includes a cylinder 10, a slider 20, an elastic reset component 30 and a fixed support 40. The slider 20 is fixedly connected to the cylinder rod 11 of the cylinder 10 as a whole, so that the extension or retraction of the cylinder rod 11 when the cylinder 10 is ventilated can drive the slider 20 to extend or retract synchronously; the elastic reset component 30 is used to drive the slider 20 to reset when the cylinder 10 is de-energized; two brake connecting rods 50 are symmetrically rotatably connected on the fixed support 40, and the brake connecting rods 50 are rotatably connected to the slider 20. When the slider 20 moves linearly, the two brake connecting rods 50 are driven to realize the opening and closing action; a brake component 60 is provided at one end of the brake connecting rod 50, and the brake components 60 of the two brake connecting rods 50 are arranged oppositely. Then, when the cylinder 10 is de-energized and causes the motion mechanism to have a risk of falling, the elastic reset component 30 can drive the slider 20 to reset, and then drive the two brake connecting rods 50 to quickly lock the motion mechanism to prevent the motion mechanism from falling and causing personal injury and mechanism damage.

[0043] In order to make the entire mechanism run smoothly and reliably, in some embodiments of the present application, the anti-fall brake mechanism also includes a fixed guide component, which is fixedly arranged and cooperates with the sliding guide of the slider 20 to guide the telescopic movement of the slider 20.

[0044] Furthermore, the fixed guide component is a guide post 80, which is in multiple numbers and one end of which is fixedly connected to the cylinder body 12 of the cylinder 10, and the fixed support 40 is fixedly connected to the other end of the guide post 80. Specifically, a flange plate 13 is fixedly provided on the top of the cylinder 10, and the guide post 80 is fixedly provided on the flange plate 13. In order to take into account both the guiding function and the cost advantage, two guide posts 80 are provided, and they are symmetrically provided on opposite sides of the slider 20.

[0045] In some embodiments of the present application, the slider 20 is coaxially arranged with the cylinder rod 11, and two brake connecting rods 50 are symmetrically arranged above the two opposite sides of the slider 20. The two opposite sides of the slider 20 are respectively provided with an intermediate connecting rod 90, the first end of the intermediate connecting rod 90 is rotatably connected to the slider 20, and the second end is rotatably connected to one end of the brake connecting rod 50, the middle part of the brake connecting rod 50 is rotatably connected to the fixed support 40, and the brake component 60 is arranged on the other end of the brake connecting rod 50. That is, by providing the intermediate connecting rod 90 to realize the rotational connection between the brake connecting rod 50 and the slider 20, the movement of the brake connecting rod 50 can be smoother and more flexible.

[0046] In some embodiments of the present application, Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the brake link 50 includes a vertical section 51 and an inclined section 52, the braking component 60 is arranged on the first end of the vertical section 51, the braking components 60 of the two brake links 50 are arranged face to face, and the second end of the vertical section 51 is fixedly connected to the first end of the inclined section 52 as a whole.

[0047] In some embodiments of the present application, the rotational connection portion between the brake connecting rod 50 and the fixed support 40 is a fixed connection portion between the vertical section 51 and the inclined section 52, the second end of the intermediate connecting rod 90 is rotationally connected to the second end of the inclined section 52, the first end of the inclined section 52 is close to the axis of the cylinder rod 11, and the second end of the inclined section 52 is away from the axis of the cylinder rod 11.

[0048] Of course, the slider 20 can also be rotatably connected to the brake connecting rod 50 in other ways, such as directly rotatably connected to the brake connecting rod 50. Specifically, the slider 20 is coaxially arranged with the cylinder rod 11, and the two brake connecting rods 50 are symmetrically arranged above the opposite sides of the slider 20, and one end of the brake connecting rod 50 is hinged to the fixed support 40, and the brake component 60 is arranged on the other end of the brake connecting rod 50; the two brake connecting rods 50 are respectively provided with long holes extending along their length directions, and the slider 20 is correspondingly provided with guide protrusions, and the guide protrusions are slidably matched with the long holes. When the slider 20 telescopes and moves, due to the sliding match between the guide protrusions and the long holes, the two brake connecting rods 50 will be driven to realize the opening and closing action.

[0049] Since the brake connecting rod 50 is opened and closed by rotation, the motion trajectory of the brake component 60 is an arc, and a part of the brake surface of the brake component 60 (i.e., the surface that fits with the moving mechanism to be braked, such as the Z-axis side) will first contact the moving mechanism to be braked, and the other part will contact the moving mechanism to be braked later, that is, the contact time between the brake surface and the moving mechanism to be braked is different, and the wear degree of the brake surface of the brake component 60 is different. After a long period of use, the brake surface of the brake component 60 will not be completely fitted with the moving mechanism to be braked, affecting the reliability of the brake locking.

[0050] To solve the above technical problems, in some embodiments of the present application, the braking component 60 includes a brake pad 61 and a brake hinge seat 62, one end of the brake hinge seat 62 is rotatably connected to the first end of the vertical section 51, and the brake pad 61 is installed on the brake hinge seat 62; the rotation axis of the brake hinge seat 62 is parallel to the rotation axis of the brake connecting rod 50; an adjusting component is provided on the vertical section 51, and the adjusting component rests on the other end of the brake hinge seat 62, and the position of the adjusting component relative to the brake hinge seat 62 is adjustable to adjust the initial angle of the brake hinge seat 62.

[0051] As Figure 1 , Figure 5 and Figure 6 Taking the perspective shown in FIG. 1 as an example, the first end of the vertical segment 51 (i.e. Figure 1 , Figure 5 and Figure 6 A brake hinge seat mounting groove 53 is formed at the top of the vertical section 51 as shown in the figure. The brake hinge seat 62 is rotatably connected to the first end of the vertical section 51 through a rotating shaft 54. The initial angle of the brake hinge seat 62, that is, the tilting angle of the brake hinge seat 62 relative to the vertical section 51, can be changed by rotating the brake hinge seat 62.

[0052] The initial angle of the brake hinge seat 62 is specifically adjusted by the adjusting component. The adjusting component can be an adjusting screw 100, which is vertically arranged to the rotating shaft 54 ​​of the brake hinge seat 62. A penetrating screw hole is provided on the vertical section 51. The adjusting screw 100 cooperates with the screw hole, and the screw holes are exposed at both ends. The small head end of the adjusting screw 100 abuts against the end of the brake hinge seat 62. By rotating the adjusting screw 100 clockwise or counterclockwise, the lifting angle of the brake hinge seat 62 by the adjusting screw 100 is changed, that is, the tilting angle of the brake hinge seat 62 relative to the vertical section 51 is changed, and then the tilting angle of the brake pad 61 relative to the vertical section 51 is changed.

[0053] When the brake pad 61 is partially worn due to long-term use, the tilting angle of the brake hinge 62 and the brake pad 61 can be adjusted by adjusting the screw 100, so that the brake pad 61 can contact and hold the moving mechanism to be braked with the largest area as possible to ensure braking reliability.

[0054] Furthermore, an elastic clamping component 110 is provided between the vertical section 51 and the brake hinge seat 62. The elastic clamping component 110 is in a compressed state, and its elastic force acts on the brake hinge seat 62 to keep the brake hinge seat 62 and the adjusting screw 100 tightly against each other, thereby preventing the brake hinge seat 62 from shaking, thereby preventing the brake hinge seat 62 from shaking and causing a decrease in braking reliability, thereby further ensuring braking reliability.

[0055] In some embodiments of the present application, the elastic clamping component 110 is a spring, and a spring mounting groove 63 with an opening toward the vertical section 51 is formed on the brake hinge seat 62. The spring is arranged in the spring mounting groove 63, one end of which extends out through the notch of the spring mounting groove 63 and rests on the vertical section 51, and the other end rests on the bottom of the spring mounting groove 63. The spring is in a compressed state, so that the brake hinge seat 62 is pressed against the adjusting screw 100.

[0056] In order to realize the disassembly and replacement of the brake pad 61, it is detachably mounted on the brake hinge seat 62, for example, detachably connected by screws. When the brake pad 61 is severely damaged by friction, the screws can be removed and the brake pad 61 can be replaced.

[0057] Of course, the brake component 60 may also be other structures, such as directly installing a brake material on the first end of the vertical section 51 to achieve braking.

[0058] In some embodiments of the present application, the anti-fall brake mechanism further includes a connecting plate 120, and the fixed support 40 is fixedly connected to the connecting plate 120. The connecting plate 120 is transitionally connected to the external base or frame, or can be directly connected, so that the entire anti-fall brake mechanism is installed on the device where the motion mechanism to be braked is located.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
