Description

Technical Field

[0001] The present invention relates to a brake for an elevator, a moving body for an elevator, and an elevator. Background Art

[0002] In an elevator, a car is usually vertically displaced along a travel path between different floors or levels in a building. Here, at least in high-rise buildings, an elevator type is used, in which the car is held by a rope-like or belt-like suspension and is displaced in an elevator shaft by moving the suspension by means of a drive machine. In order to at least partially compensate for the load of the car moved by the drive machine, a counterweight is fixed to the opposite end of the suspension. The car and the counterweight are moving bodies of an elevator installation. In order to protect the moving bodies against falling along the travel path, the moving bodies are often equipped with brakes. Such a moving body brake can be configured as a hydraulic brake.

[0003] US9688510B2 shows a hydraulic brake, in which a spring for pre-tensioning the hydraulic brake is received in a brake cylinder. Additionally, US10450165B2 shows a spring for pre-tensioning a hydraulic brake in a brake cylinder. For safety reasons, such a spring is usually designed to be pre-tensioned by the spring in the braking position and is opened by a hydraulic actuator. US2017 / 036888 shows a hydraulic brake with a spring arranged separately on a rod mechanism.

[0004] With this structural approach, the selection of the spring is greatly restricted. The spring must be assembled in a corresponding cylinder bore. Since the spring is located in the cylinder bore, the replacement or adjustment of the spring is relatively difficult. Summary of the Invention

[0005] Therefore, an object of the present invention is to provide a brake that can be better adjusted and maintained.

[0006] According to a first aspect of the present invention, a brake achieves this object. The brake for a moving body of an elevator includes: a housing, a brake caliper, a first brake lining, a second brake lining, and a hydraulic element. The brake caliper is designed to generate a clamping force of the brake along a second action line and transmit the clamping force to the first brake lining and the second brake lining. The brake caliper encloses the housing. The hydraulic element is designed to apply an opening force to the brake caliper along a first action line to open the brake caliper. The opening of the brake caliper opens the brake. The first action line and the second action line are spaced apart from each other. The brake caliper is designed as a C-shaped spring group.

[0007] According to a second aspect of the present invention, a moving body achieves this object. The moving body has a brake according to the first aspect of the present invention.

[0008] According to a third aspect of the present invention, an elevator achieves this object. The elevator has a brake according to the first aspect of the present invention or a running body according to the second aspect of the present invention.

[0009] The feasible features and advantages of the embodiments of the present invention can be considered to be based on the concepts and cognitions introduced below, including but not limited to the present invention.

[0010] The brake for the running body of the elevator is used to generate a braking force on the brake rail, and this braking force acts in the opposite direction to the movement direction of the running body. The running body can be a car or a counterweight. The housing is mainly used to be fixed on the running body, or for example, there is a possibility of being movably fixed on the running body. The hydraulic element is preferably firmly connected to the housing. The brake caliper is used to pre-tighten and store energy in the pre-tightened state to apply the energy as a clamping force to the first and second brake linings as needed.

[0011] The brake caliper is pre-tightened in an openable manner. In order to open the brake caliper, an opening force and / or a clamping force can be applied to the brake caliper.

[0012] The brake can be activated. Then, due to the contraction of the hydraulic element, no opening force acts along the first action line. Along the second action line, when the brake is activated, the force of the brake caliper that still continues to open is transmitted as a clamping force to the first and second brake linings. With this clamping force, the first and second brake linings are pressed onto the brake rail or can be pressed onto the brake rail. The clamping force is related to the opening of the brake caliper. The more the brake caliper is opened, the greater the clamping force. The opening of the brake caliper depends, for example, on the intensity of wear of the brake lining. The more worn the brake lining is, the less the brake caliper is opened, and the smaller the clamping force. However, the clamping force can also be adjusted by changing the thickness of the pre-tightening element with variable thickness. The thicker the pre-tightening element is set, the greater the clamping force. The braking force can also be adjusted by the clamping force.

[0013] The brake can be opened. Then no clamping force acts along the second action line because the brake lining does not contact the brake rail. Along the first action line, the hydraulic element is designed to open the brake caliper. The force applied by the hydraulic device is called the opening force. The opening force depends on the opening of the brake caliper. The more the brake caliper is opened by the hydraulic element, the greater the opening force. Since the hydraulic device opens the brake caliper wider than in the case when the brake is activated, the opening force of the brake is greater than the clamping force.

[0014] In the transition region between the activated brake and the opened brake, both the opening force and the clamping force can contribute to the partial opening of the clamping element, for example, each opening by half.

[0015] According to a preferred embodiment, the hydraulic support and the support transmit the opening force to the brake caliper, where the hydraulic support and the support are designed as thrust support points, and / or

[0016] The first brake support and the second brake support transmit the clamping force to the brake caliper, wherein the first brake support and the second brake support are configured as thrust support points.

[0017] The thrust support point is suitable for transmitting a pushing force from a first body to an adjacent second body. Preferably, at least one of the two bodies arches outward with a convex first arch radius. Preferably, the other body is implemented as flat. Alternatively, the second body can also arch outward. It is also advantageous if the second body is designed at the thrust support point to arch inward with a second arch radius greater than the first arch radius. Thereby, the arched portion of the first body is stably located in the recess of the arch of the second body. Here, the local arch geometry can be designed as cylindrical, elliptical or spherical.

[0018] The hydraulic support is a thrust support point between the brake caliper and the hydraulic component, at which the opening force generated by the hydraulic component is transmitted to the brake caliper as a pushing force. The support is a thrust support point between the brake caliper and the hydraulic component, at which the opening force generated by the hydraulic component is directly or indirectly transmitted as a pushing force from the housing to the brake caliper.

[0019] The hydraulic support and the support are thus located on a first action line. Similarly, the first brake support is a thrust support point at which the brake caliper directly or indirectly transmits the clamping force to the first brake lining. In addition, the second brake support is a thrust support point at which the brake caliper directly or indirectly transmits the clamping force to the second brake lining.

[0020] The first brake support and the second brake support are located on a second action line. The clamping force is transmitted along the second action line from the first brake support to the first brake lining and from the second brake support to the second brake lining. The first and second brake linings are pressed against the brake rail with the clamping force. The braking force is generated on the brake rail by friction with this clamping force. The braking force is then introduced from the brake lining via the housing into the moving body and decelerates the moving body.

[0021] The first and second action lines preferably extend parallel to each other.

[0022] Thus, the force acting on the brake caliper is basically introduced through four thrust support points. In addition, the brake caliper encloses the housing. The brake caliper is also located outside the housing and basically only has four thrust support points for connecting to the rest of the brake. Therefore, for installation, the brake can very easily enter the housing and separate one or more brake calipers. The entire brake may be very heavy and thus difficult to install. The housing and one or more brake calipers each have a weight that can be easily manipulated by the fitter. These components of the brake can be, for example, less than 10 kg or less than 5 kg. Therefore, the installation of each component (such as the housing or each brake caliper) is easy to carry out. Thus, the brake can be easily assembled. In addition, the brake caliper can be easily accessed outside the housing. Therefore, the brake caliper can be easily monitored, maintained or adjusted.

[0023] According to a preferred embodiment, the hydraulic element is firmly mounted on the housing. The hydraulic element has a hydraulic piston. The hydraulic piston is designed to push the hydraulic support and thereby generate an opening force.

[0024] In particular, a surface can be designed on the hydraulic piston such that the hydraulic piston can act directly on the hydraulic support. For this purpose, the contact surface of the hydraulic piston can be designed to be slightly arched towards the hydraulic support. Alternatively, especially when using multiple hydraulic elements or a hydraulic element with multiple hydraulic pistons, the hydraulic support can be configured on another connecting carrier, namely a hydraulic carrier plate. The hydraulic carrier plate distributes the force from one or more hydraulic elements to one or more brake calipers. One hydraulic element can open multiple brake calipers. Alternatively, multiple hydraulic elements can open one brake caliper. In addition, multiple hydraulic elements can open multiple brake calipers, where the number of hydraulic elements and the number of brake calipers can be the same or different. The opening by one or more hydraulic elements is achieved by applying an opening force.

[0025] The hydraulic element includes a hydraulic cylinder and a hydraulic piston. Preferably, the hydraulic cylinder is fixed on the housing or constructed on the housing. The hydraulic piston preferably moves linearly along a first line of action. The hydraulic element is configured in such a way that the hydraulic element has a small clearance relative to the brake caliper in the retracted position. In the extended position, the hydraulic element opens the brake caliper to such an extent that the brake lining is lifted off the brake rail, i.e., is opened.

[0026] An opening force is generated when the brake is opened by the hydraulic element. The opening force opens the brake caliper, thereby opening the brake. The first and second brake linings are lifted off the brake rail when opened. The clamping force is generated by the brake caliper because the brake caliper is pre-tightened. When the brake is activated, the clamping force acts on the brake caliper. Since the hydraulic element does not exert a force on the brake caliper in this state, this clamping force mainly acts on the first brake lining and the second brake lining.

[0027] The line of action is a straight line. The force acts on the body along the line of action. For example, in the state where the brake is open, the hydraulic piston pushes the brake caliper. Therefore, opposite opening forces are applied to the brake caliper at two points. The line of action connects these two points and extends along the direction of the two opposite opening forces.

[0028] Preferably, the moving body has at least two brakes. Advantageously, two brake circuits are each operated with two brakes, wherein the first brake of the brake circuit can generate a braking force on the first brake rail. The second brake of the same brake circuit can generate another braking force on the second brake rail that extends opposite to the first brake rail on the moving body.

[0029] The brake caliper can be configured as a brake clamp, wherein the brake clamp includes a first clamping arm, a second clamping arm, a brake clamp hinge, and a brake clamp spring. Preferably, the brake clamp hinge is arranged between the brake clamp spring configured as a compression spring and the thrust support point. The compression spring can include, for example, a stack of disc springs. The brake caliper designed in this way can be opened along the first line of action by a hydraulic device. Along the second line of action, the caliper brake can generate a clamping force acting on the first brake lining and the second brake lining. The caliper brake is held on the housing by a clip, for example. The clip allows slight movement relative to the housing, which is especially caused by the deformation of the caliper brake. However, the clip ensures that the transmission of the clamping force and the opening force is guaranteed.

[0030] Four thrust support points can be machined on the first and second clamping arms. Preferably, these clamping arms are castings and the arches of these thrust support points can be designed to be spherical.

[0031] The brake caliper is designed as a C-spring group. A C-spring group, i.e., a combination composed of multiple layers of C-springs, is known from brakes and especially from fall arrest devices. The C-spring group has many advantages over other springs. For example, the C-spring group has a longer service life. In addition, the safety is higher because only a limited reduction in spring force occurs even when one of the springs fails. In addition, the remaining intact springs usually generate a clamping force sufficient to reliably brake the moving body.

[0032] Four thrust support points can be machined on each individual C-spring. Preferably, the cylindrical shape of the arch of the thrust support point is formed on the C-spring group. Therefore, the contact surface for transmitting force at the thrust support point is designed to be elongated or straight.

[0033] According to a preferred embodiment, a plurality of C-shaped spring groups arranged on the housing are opened with a plurality of hydraulic elements. Preferably, each hydraulic element is associated with exactly one C-shaped spring group. Thereby, the brake is modularly constructed. A stronger brake can be obtained not only by stronger C-shaped spring groups with a higher spring constant, but also a stronger brake can include one or more additional C-shaped spring groups. Thus, a plurality of C-shaped spring groups with the same spring constant produce a greater spring force than a single C-shaped spring group with the same spring constant. A brake with a plurality of C-shaped spring groups can thus generate a greater clamping force and thereby a greater braking force.

[0034] According to a preferred embodiment, the first brake lining is firmly connected to the housing, in particular by means of a first brake lining retainer.

[0035] Along the second line of action, the clamping force is transmitted from the first brake support to the first brake lining. The first brake lining retainer is likewise located on the second line of action. The brake lining retainer can have an arch on the side facing the brake caliper or can be formed flat. Preferably, the brake lining retainer has an arched recess into which the arch of the brake caliper fits.

[0036] The brake lining retainer is designed towards the brake lining such that the brake lining retainer can preferably receive the brake lining via form fit. In addition, the brake lining can preferably be fixed by bolts or other suitable connecting means. The brake lining is preferably replaceable or exchangeable.

[0037] According to a preferred embodiment, the second brake lining is guided linearly on the housing. Here, the linear guidance, i.e., the linear guidance of the second brake lining on the housing, takes place in the direction of the second line of action and preferably along the second line of action. For example, the linear guidance means can be guided by a sliding bearing, a needle bearing or a ball bearing.

[0038] Alternatively, the first brake lining can also be guided linearly on the housing. This can be achieved by any linear guidance means. The linear guidance means can be formed, for example, as a push rod guided in the housing as in the second brake lining.

[0039] According to a preferred embodiment, the linear guidance on the housing is achieved by a push rod, wherein the push rod is cylindrically shaped and passes through a hole in the housing, and the push rod transmits the clamping force from the second brake support to the second brake lining.

[0040] The shell surface of the push rod configured in a cylindrical shape and the shell surface of the hole together form a sliding bearing, and the push rod can move linearly in this sliding bearing. The push rod transfers the clamping force from the second brake support to the second brake lining. The second brake support can be directly connected to the push rod, particularly by direct contact occurring between the push rod and the second brake support, or it can be indirectly connected to the push rod by the brake support transferring the clamping force to other shaped bodies located between the brake support and the push rod. The push rod thus guides the clamping force to the second brake lining. Preferably, the brake has a plurality of push rods. Here, for example, a brake caliper can be assigned to each push rod.

[0041] A support plate can be arranged between the push rod or push rods and the brake caliper or brake calipers. The support plate distributes the clamping force from one or more brake calipers to the push rod or push rods. In particular, the support plate can transfer the clamping force of multiple brake calipers to one push rod, or the support plate can transfer the clamping force of the brake caliper to multiple push rods. In particular, the clamping force of multiple brake calipers can also be transferred to multiple push rods, where the number of brake calipers and the number of push rods can be the same or different.

[0042] The support plate can have a protruding or recessed arch and can be used as a thrust support point.

[0043] According to a preferred embodiment, the auxiliary spring preloads the second brake lining in the direction towards the second brake support. Thereby, the second brake lining is pushed away from the track in the open brake caliper. Thereby, a gap between the second brake lining and the track is reliably created. The brake can be guided on the brake track by means of guide shoes. Preferably, the guide shoes are mounted on the housing of the brake. Thereby, the brake can be guided very precisely along the brake track, particularly more precisely than the car to which the brake is fixed. Alternatively, the brake can be firmly connected to the running body and be guided by the guide shoes of the running body. The gaps on both sides of the brake track during running are reliably maintained by the guiding device. By means of the auxiliary spring, the push rod or push rods (or alternatively these support plates) on the second brake support remain in contact with one or more clamping elements. Thereby, it is reliably prevented that the second brake lining moves towards the brake track without being pressed by the brake caliper.

[0044] Alternatively, for example, the permanent magnets can also be installed in such a way that an adhesive force is generated between the brake caliper and the push rod or the support plate on the second brake support. This adhesive force can be used to maintain a spacing between the second brake lining and the brake rail. As a result, the second brake lining is not only unloaded but is also actively pulled away from the brake rail. Thereby, a gap is reliably created between the brake rail and the second brake lining. Now, the guide shoes are preferably arranged in such a way that the housing is aligned with the brake rail, such that this gap is preferably evenly distributed on both sides of the brake rail.

[0045] According to a preferred embodiment, the push rod has a shaft head for positively transmitting a force to the second brake lining profile, in particular by means of the second brake lining holder. The advantage is that the braking force can be introduced into the push rod via the shaft head. Then, the one or more push rods transmit the braking force to the housing.

[0046] Thus, the second brake lining can be directly fixed, for example by means of bolts, to the respective push rods. Preferably, the second brake lining holder is firmly connected to the push rod or the plurality of push rods. The second brake lining holder can be integrally formed with the push rod or the plurality of push rods.

[0047] Preferably, the second brake lining is connected to the push rod by means of the second brake lining holder. Thus, the second brake lining is designed to be replaceable, like the first brake lining.

[0048] According to a preferred embodiment, the first brake lining and / or the second brake lining is replaceable.

[0049] Preferably, the first and second brake linings are configured to be replaceable in such a way that the first brake lining holder is firmly connected to the housing and the second brake lining holder is firmly connected to the one or more push rods. Then, the first and second brake linings, which are preferably of the same construction, can be simply replaced on the first or second brake lining holder. The brake linings can be connected to the brake lining holder, for example, by means of a bolted connection and / or a positive connection.

[0050] According to a preferred embodiment, the support body can be removed and is designed to be pressed onto the support. The support body lies on the first line of action. The support body can have an arched depression on its surface, against which the outwardly arched contact surface of the brake caliper abuts. Here, the support is formed in this embodiment by the contact area of the support body with the brake caliper. Preferably, the support body is a cubic block with arched depressions on both sides. Description of the Drawings

[0051] Other advantages, features and details of the invention result from the following description of embodiments and from the figures, in which the same or functionally identical elements are provided with the same reference numerals. The figures are only schematic and not drawn to scale.

[0052] Here:

[0053] Figure 1 An elevator is shown,

[0054] Figure 2 A brake with a C-shaped spring as a brake caliper is shown,

[0055] Figure 3 A brake with a brake clip as a brake caliper is shown,

[0056] Figure 4 A sectional view of the brake is shown. Detailed Description

[0057] Figure 1 An elevator 1 is shown. In the elevator 1, a car 6 is vertically displaced between different floors 4 or levels in a building. To compensate for the weight of the car 6, the elevator also includes a counterweight 7. The car 6 and the counterweight 7 can be referred to as running bodies 2 because they are displaced along a track that also serves as a brake rail 5. To brake, i.e., to retard or hold the running bodies stationary when needed, the running bodies have brakes 10.

[0058] For the riding comfort of passengers, it is advantageous that the running bodies and in particular the car 6 can move slightly horizontally relative to the brake rail 5. The brake rail always has small irregularities, and due to the elastic support with a gap of 4 mm to 5 mm, the car 6 can follow such irregularities with a delay. However, the brake preferably has only a gap of 1 to 2 mm. Therefore, the brake 10 is guided on the car 6 in a floating manner on a brake sliding support 12. Thereby, the brake 10 can reliably follow the irregularities of the brake rail 5.

[0059] The drive of the elevator is located in the machine room 3.

[0060] The brake 10 is supported on the car 6 in a floating manner by the brake sliding support 12. Therefore, the brake 10 can move horizontally along the axis of the brake sliding support 12 in order to be able to reliably follow the irregularities of the track. At the same time, the brake sliding support 12 can transfer the braking force to the car. Of course, the brake sliding support 12 can also be provided for the brake 10 on the counterweight 7. (Not shown in Figure 1 for reasons of clarity)

[0061] Figure 2 and Figure 3Shows two alternative embodiments of the brake caliper 16 on brakes 10 of the same type in other respects. The fixing area 15 is used to fix the brake on the moving body 2, and in particular on the movable brake sliding support at the car (see Figure 1 ).

[0062] The brake caliper 16 encloses the housing 14 of the brake 10. Here, the brake caliper 16 is designed to be able to open. In Figure 2 , the brake caliper 16 is designed as a spring 17 for this purpose. Here, the spring 17 consists of a C-shaped spring group 26, which is composed of individual C-shaped leaf springs 27. The spring 17 generates the clamping force of the brake 10. (In Figure 4 , the individual C-shaped leaf springs 27 and the C-shaped spring group 26 can be seen more clearly.) In Figure 3 , the brake caliper 16 is configured as a brake clip. The brake clip includes a first clamping arm 21 and a second clamping arm 22 connected by a brake clip hinge 23. Here, the first clamping arm 21 and the second clamping arm 22 enclose the housing 14 of the brake 10. The brake clip has a brake clip spring 20 to generate the clamping force of the brake clip.

[0063] The hydraulic element 18, in particular the hydraulic piston 19 and the bracket body 28, are arranged along the first action line 51. In the braking position, the hydraulic piston 19 is retracted into the hydraulic element 18. There is preferably a gap between the brake caliper 16 and the hydraulic piston 19 in the hydraulic support 30. There is a gap in the support 31 and the brake caliper is preferably spaced apart from the bracket body 28. Therefore, no force is transmitted along the first action line 51.

[0064] The clamping force generated by the brake caliper 16 is completely transmitted along the second action line 52. In the first brake support 41, the clamping force is transmitted to the housing 14 via the preloading element 80. In addition, the housing 14 is firmly connected to the first brake lining holder 63 and the first brake lining 61 held thereon. On the opposite side, in the second brake support 42, the clamping force is transmitted to the push rod 71 through the support plate 43. In addition, the push rod 71 is firmly connected to the second brake lining holder 64 and the second brake lining 62 held thereon. The push rod 71 is guided linearly in the linear guide 70. The linear guide 70 is designed as a hole. In the braking position, the brake rail is clamped between the first brake lining 61 and the second brake lining 62, and thus a braking effect is generated. The brake rail is not shown, but a spacing is generated between the first brake lining 61 and the second brake lining 62, so that the clamping force that opens the brake caliper 16 acts along the second action line 52.

[0065] To reach the open position ( Figure 2 and Figure 3(not shown), the hydraulic fluid is pressed into the hydraulic component 18 through the hydraulic pipeline 102. The hydraulic piston 19 presses against the hydraulic support 30. Thereby, the brake caliper 16 opens together with the support body 28 pressed against the support 31. Thereby, an opening force is formed along the first action line 51. The clamping force transmitted along the second action line 52 decreases. When the hydraulic piston 19 is fully extended, there is a gap between the first brake lining 61 and the second brake lining 62 relative to the brake rail. The contact with the second brake support is maintained. For this purpose, the support plate 43 can be designed magnetically so that it moves together with the brake caliper 16. Or as Figure 4 shown, the push rod 71 is pre-tensioned by an auxiliary spring.

[0066] Figure 4 shows a sectional view of the brake 10 having a C-shaped spring group 26, as already shown in Figure 2 it. Figure 4 shows Figure 2 a detailed variant of the embodiment of the brake 10 in Figure 4 shows how the C-shaped spring group 26 is formed by stacking individual C-shaped springs 27. Two hydraulic components 18 respectively open two C-shaped spring groups 26, so that the brake 10 has four C-shaped spring groups 26. Each two C-shaped spring groups 26 are respectively pressed against one of the two support plates 43. Each support plate 43 is connected to three push rods 71. All six push rods 71 are connected to the second brake lining retainer 64 at the respective other ends. The push rods 71 are respectively supported in the linear guide 70. Three auxiliary springs 75 are used to lift the second brake lining 62 away from the brake rail, and the support plate 43 also remains in contact with the brake caliper 16 in the open state.

[0067] Each of the two pre-tensioning elements 80 has a first load-bearing element 81, a second load-bearing element 82, a first wedge element 91 and a second wedge element 92. The traction mechanism 93 designed as a bolt extends through the threadless hole in the second wedge element 92 and is screwed into the thread in the first wedge element 91. By tightening the bolt, the pre-tensioning element 80 is opened.

[0068] Finally, it should be noted that concepts such as "having", "including", etc. do not exclude other elements or steps, and concepts such as "a" or "one" do not exclude a plurality. In addition, it should be noted that the features or steps introduced with reference to one of the foregoing embodiments can also be used in combination with other features or steps of the foregoing other embodiments. The reference signs in the claims should not be regarded as limiting.
