Technical Field

[0001] This invention relates to the field of vibration machinery and equipment technology, specifically to a locking device for vibration equipment and its application device. Background Technology

[0002] In the vibratory machinery industry, people utilize the kinetic energy generated by vibration and convert it into mechanical energy through various technical means to design vibratory machinery with various functions. Common applications include vibratory crushers and vibratory grinding and mixing machines.

[0003] While using vibration to generate kinetic energy and convert it into mechanical energy to achieve the desired result, it also has a certain impact on the vibrating machinery itself. In particular, the locking structure that controls the flipping or rotation process of the vibrating machinery often fails or breaks, which further exacerbates the failure of the vibrating machinery. If not detected in time, it can even lead to personal injury accidents and cause significant economic losses to the production enterprise.

[0004] Currently, the locking devices or structures used in the vibratory machinery equipment industry include pin-type, shaft-pin type, cam-locking type, hook-claw type, chain-brake type, and brake-brake type. Although numerous locking methods are employed, and even frequent replacements of locking structures are made, the occurrence of the aforementioned adverse factors cannot be effectively reduced. This is both labor-intensive and time-consuming, and cannot guarantee the safety of equipment operation. Therefore, the above situation has always been a pressing technical challenge for the vibratory machinery equipment industry. Summary of the Invention

[0005] To address the aforementioned shortcomings of existing technologies, this invention proposes a locking device for vibration equipment. This invention can achieve the locking function of controlling the flipping or rotating process of vibration machinery, effectively avoiding the adverse effects of equipment vibration on the locking structure's performance.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A locking device for a vibration device includes a rotating support frame and a rotating component. One end of the rotating support frame is provided with a first locking structure and a second locking structure. The rotating component is provided with positioning structures that cooperate with the first locking structure and the second locking structure respectively. A buffer pad is provided on one side of the first locking structure; and / or, a buffer pad is provided on one side of the second locking structure.

[0008] Furthermore, the center connection line of the first locking structure and the second locking structure coincides with the center connection line of the two positioning structures on the rotating component on the Y-axis in the XY plane.

[0009] Further, the center connecting line of the first locking structure and the second locking structure and the center connecting line of the two positioning structures on the rotating part do not coincide on the XY plane and are parallel to the Y axis.

[0010] Further, the second locking structure is located on the outer side or the inner side of the rotating support frame.

[0011] Further, the first locking structure comprises a locking base, the locking base is sequentially provided with a locking pressing plate and a lock tongue from top to bottom, the other side of the locking base is provided with a screw handle for fixing the locking pressing plate; a buffer pad is arranged between the locking base and the lock tongue; and / or, a buffer pad is arranged between the lock tongue and the locking pressing plate.

[0012] Further, the locking base is provided with a tightening jack screw for respectively adjusting the lock tongue and the locking pressing plate.

[0013] Further, the screw handle comprises a handle and a tightening screw rod, and the handle and the locking pressing plate are in spherical surface contact.

[0014] Further, the locking base movably installs the lock tongue, the locking pressing plate and the tightening screw rod through shaft pins.

[0015] Further, the positioning structure comprises a base block and an L-shaped adjusting block, and the base block and the adjusting block and the adjusting block and the rotating part are connected through bolts respectively.

[0016] Further, the positioning structure comprises a base block, an adjusting block, a connecting plate and a wedge-shaped block, the base block and the adjusting block are provided with the wedge-shaped block, and one side of the base block is provided with the connecting plate for moving the wedge-shaped block.

[0017] The present application has the beneficial effects:

[0018] 1. The present application sets the positioning structure on the upper and lower sides of the rotating part respectively and sets the corresponding locking structure on the rotating support frame, each positioning structure and the corresponding locking structure are single-point locking, thereby forming a four-point locking mode.

[0019] The four-point locking mode is in a static zero-force state at the contact surface of the first locking structure / second locking structure and the corresponding positioning structure at the beginning, and during use, the vibration excitation rotating force generated by the vibration device and the reverse force generated by the damping system are absorbed through the structure layout between the first locking structure / second locking structure and the positioning structure and the setting of the buffer pad, and the damage caused by vibration is effectively eliminated.

[0020] Moreover, during use, the contact surface between the first locking structure / second locking structure and the corresponding positioning structure always bears a unidirectional force, which enables the needle rollers and bearings to withstand a uniform circumferential force in the rolling direction. This prevents the needle rollers and bearings from being subjected to an additional "locking force" applied to the locking device from the outside, thus protecting the needle rollers and bearings and improving their service life.

[0021] 2. The present invention adopts a flexible contact method in the connection of each component of the first locking structure. This method effectively absorbs the impact generated by vibrating mechanical equipment, which can not only improve the service life of the first locking structure, but also prevent vibration from affecting the locking effect, making it reliable in use.

[0022] Furthermore, it avoids equipment failures and personnel safety hazards caused by the failure of the first locking structure, ensuring product quality and reliability, and directly providing scientific and powerful technical support for manufacturers of vibrating machinery and equipment, enabling them to generate economic value through technical means.

[0023] 3. The first locking structure of the present invention is provided with a tightening set screw, which can adjust the clamping and retaining force of the corresponding component (locking tongue or locking plate) to ensure the reliable use of the device.

[0024] 4. The second locking structure provided in this invention can be installed in an embedded manner, saving space, avoiding interference with surrounding components, making it easy to use and install, and effectively preventing damage caused by unnecessary external impacts.

[0025] 5. The positioning structure of this invention has diverse applications and can be adjusted according to installation or usage requirements. It is suitable for low-precision or high-precision installations, adapts to different working conditions, and meets the needs of different customers. The adjustment method is simple, easy to operate, and has good performance. Attached Figure Description

Detailed Implementation

[0043] To better understand the present invention, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of the present invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0044] Example 1

[0045] A locking device for a vibration device, such as Figures 1-3 As shown, the device includes a rotating support frame 5 and a rotating component 6. A damping system is also provided on one side of the rotating support frame 5, which includes a damping ball and a spring. The rotating support frames 5 at both ends of the vibration device are connected to the main shaft via embedded bearings, and the rotating component 6 is also connected to the main shaft via embedded bearings. This structure is the same as that used in existing vibration devices and will not be described further in this application.

[0046] The rotating support frame 5 is provided with a first locking structure 1 and a second locking structure 2 at one end, and a positioning structure 3 is provided on one side of the first locking structure 1 and the second locking structure 2 respectively. The positioning structure 3 cooperates with the corresponding first locking structure 1 and the second locking structure 2 respectively.

[0047] A buffer pad 102-1 is provided on one side of the first locking structure 1; and / or, a buffer pad 102-1 is provided on one side of the second locking structure 2. The buffer pad 102-1 uses single-sided adhesive, making it easy and quick to apply, inexpensive, long-lasting, and easy to replace, saving maintenance time and costs. The specifications of the buffer pad 102-1 can be selected according to the components it is installed on.

[0048] While locking the rotating component 6, the buffer pad 102-1 on the first locking structure 1 or the second locking structure 2 absorbs the destructive force generated by the reverse force, extends the service life of the first locking structure 1, and ensures the safe operation of the vibration equipment.

[0049] Taking the locking structure at one end of the rotating support frame 5 as an example, the conventional locking structure adopts single-point locking. Conventional locking devices lock by adding additional friction (such as T-handle bolt tightening, pin type, shaft pin type, cam squeeze lock type, hook head claw type, brake type locking, etc.) or by tension (chain type locking).

[0050] The conventional locking device will cause radial or circumferential initial static superimposed force to the rolling needle and bearing of the vibration device, so that the rolling needle and bearing will bear the superimposed force of the initial locking force and the exciting force in the direction of the position where the locking force is applied when the vibration device is working, i.e. when the exciting force is applied, thereby accelerating the wear and damage of the rolling needle and bearing and reducing the working life thereof.

[0051] Before the vibration device starts to work, i.e. before the exciting force is applied, the contact surface between the first locking structure 1 / second locking structure 2 and the corresponding positioning structure 3 is in a static zero force state, i.e. when the rotating part 6 is locked to the rotating support frame 5, no external applied force (such as friction) is used for locking, thereby realizing the effect of zero force state locking.

[0052] When the vibration device is in use, the first locking structure 1 and the second locking structure 2 are respectively matched with the positioning structure 3, and the rotating part 6 rotates to bring rotating exciting force, i.e. the eccentric block on the main shaft driven by the motor generates exciting force. When the motor output shaft rotates clockwise to make the rotating part 6 rotate clockwise, the rotating exciting force is in the clockwise direction, at this time, the contact surface between the second locking structure 2 and the corresponding positioning structure 3 bears the force from the exciting force, and the buffer pad 102-1 on one side of the second locking structure 2 absorbs part of the force, and the second locking structure 2 itself will absorb the remaining force.

[0053] At the same time, the rotating exciting force also acts on the damping system, and after the damping system consumes part of the rotating exciting force, the damping system reversely acts on the first locking structure 1 and the corresponding positioning structure 3, and the reverse force is absorbed by the corresponding buffer pad 102-1 and the first locking structure 1, so that the locking of the device is in a state of dynamic balance.

[0054] Compared with the conventional locking mode which needs to bear the force from different directions, the first locking structure 1 and the corresponding positioning structure 3 and the second locking structure 2 and the corresponding positioning structure 3 always bear the force in a single direction, so that the rolling needle and bearing can bear the uniform circumferential force in the rolling direction.

[0055] Moreover, by means of the cooperation between the locking structure and the positioning structure 3 and the absorption of the force by the buffer pad 102-1, the locking effect of the rotating part 6 in the production state and the blanking state can be ensured without applying additional force from the outside, i.e. the effect of zero force state locking is realized.

[0056] Embodiment 2

[0057] Based on the embodiment 1, as shown in FIG. 2, in the XY plane, the center connecting line of the first locking structure 1 and the second locking structure 2 coincides with the center connecting line of the two positioning structures 3 on the rotating part 6 on the Y axis. Figure 1 ​

[0058] Furthermore, the first locking structure 1 and the second locking structure 2 are identical in structure. The first locking structure 1 and the second locking structure 2 are respectively plugged into the positioning structure 3, that is, the positioning structure 3 can be embedded in one end of the corresponding first locking structure 1 or second locking structure 2.

[0059] Example 3

[0060] Based on Example 1, such as Figures 2-5 As shown, on the XY plane, the center connection line of the first locking structure 1 and the second locking structure 2 does not coincide with the center connection line of the two positioning structures 3 on the rotating component 6, and both are parallel to the Y-axis. That is, when the center connection line of the first locking structure 1 and the second locking structure 2 coincides with the Y-axis, the center connection line of the two positioning structures 3 on the rotating component 6 is located on one side of the Y-axis.

[0061] In addition, the connecting lines of the force points / surfaces on the two positioning structures 3 (i.e. Figure 2 The dashed line in the diagram also has an asymmetry relative to the Y-axis, not coinciding with the Y-axis.

[0062] At this point, the first locking structure 1 and the second locking structure 2 employ different structures. For example... Figure 4 and Figure 6 As shown, when the second locking structure 2 is located outside the rotating support frame 5, two positioning structures 3 are provided at the end of the rotating component 6. The first locking structure 1 and the positioning structure 3 on the upper side of the rotating component 6 are a pair, and the second locking structure 2 and the positioning structure 3 on the lower side of the rotating component 6 are a pair. The two pairs constitute a set of fixing components.

[0063] The vibration equipment is equipped with fixed components at both ends, forming a four-point asymmetric dynamic balance locking hinge, which works together to lock the rotating support frame 5 and the rotating component 6 on both sides of the vibration machinery.

[0064] The locking hinge, composed of the first locking structure 1, the second locking structure 2, and the two positioning structures 3, uses an unconventional asymmetrical locking method. While locking the rotating component 6, it absorbs the reverse force generated by the excitation rotational force of the vibrating equipment and the damping system on the rotating support frame 5, thus achieving reliable locking.

[0065] The first locking structure 1, the second locking structure 2, and the rotating support frame 5 are connected by welding or bolts, which provides a wide range of options and can adapt to different needs and application scenarios.

[0066] When using bolted connections, all required bolt holes are countersunk bolt holes. This minimizes machining steps and saves production time and costs while ensuring the main mechanical structure and strength remain unchanged.

[0067] The positioning structure 3 is a reinforced positioning block. Its upper part cooperates with the locking tongue 102, and its lower part contacts the rotating component 6 with an arc-shaped surface. It is simple and reliable to install and use, and is suitable for high-precision installation.

[0068] like Figure 2 As shown, during normal production, the locking tongue 102 contacts the positioning structure 3 on the upper side of the rotating component 6, while the second locking structure 2 contacts the positioning structure 3 on the lower side of the rotating component 6. At this time, the rotating component 6 is fixed on the rotating support frame 5 to ensure its normal production and use. Moreover, the way the first locking structure 1 is set can effectively avoid the adverse effects of vibration generated during equipment operation on its locking effect.

[0069] like Figure 7 As shown, when production is finished and the material needs to be removed from the rotating component 6, the rotating component 6 needs to be rotated. This releases the first locking structure 1, freeing the positioning structure 3 from restriction. The rotating component 6 is then rotated until one of its positioning structures 3 contacts the second locking structure 2. Then, the first locking structure 1 contacts another positioning structure 3 on the rotating component 6, reconnecting the rotating component 6 to the rotating support frame. This facilitates material unloading and effectively eliminates the adverse effects of equipment vibration on the equipment itself or the first locking structure 1.

[0070] Example 4

[0071] Based on embodiment 3, when the second locking structure 2 is located inside the rotating support frame 5, as follows: Figures 8-10 As shown, other structures are made adaptively, namely, two positioning structures 3 are set. Relative to the rotating support frame 5, one is the outer positioning structure 3 located on the curved surface of the rotating component 6, and the other is the inner positioning structure 4 located on the end face of the rotating component 6.

[0072] The rotating support frame 5 has a cavity at one end, and a second locking structure 2 is provided in the cavity. The cavity can accommodate the inner positioning structure 4 provided at the end of the rotating component 6.

[0073] The first locking structure 1 and the two positioning structures 3 (i.e., external positioning structures 3) located on the outside of the rotating component 6 form a pair; the second locking structure 2 located on the inside of the rotating support frame 5 and the two internal positioning structures 4 on the same side end face of the rotating component 6 form a pair, and the two pairs form a set of fixing components. Two sets of fixing components are used at each end of the vibrating equipment to lock the rotating support frame 5 and the rotating component 6 on both sides of the vibrating machinery.

[0079] The upper side of the base block 301 is provided with a bolt 305 connected with the connecting plate 303, the use height of the wedge-shaped block 304 can be adjusted through the bolt 305, and the use position of the adjusting block 302 is changed. One side of the adjusting block 302 is provided with a counterbore type through hole, and the connecting plate 303 is fixed to the base block 301 by the bolt 305. The entire positioning structure 3 is connected by the bolt 305, the operation is simple, and the disassembly and installation are convenient. The specification of the bolt 305 can be adaptively selected according to the requirement of the installed part.

[0080] Embodiment 7

[0081] On the basis of embodiments 1-6, as shown in Figures 13-15 As shown, the first locking structure 1 comprises a locking base 101, the locking base 101 is sequentially provided with a locking pressing plate 103 and a lock tongue 102 from top to bottom, and the other side of the locking base 101 is provided with a tightening handle 104 for fixing the locking pressing plate 103. The locking base 101 and the lock tongue 102 are provided with a buffer pad 102-1; and / or, the lock tongue 102 and the locking pressing plate 103 are provided with a buffer pad 102-1.

[0082] The lock tongue 102 is provided with a buffer pad 102-1 on both sides, which can effectively buffer the circumferential force in two opposite directions, and protect the mechanical structure strength of the first locking structure 1. The lower side of the locking plate 103 is provided with a buffer pad 102-1, which can not only ensure the pressing and limiting of the lock tongue 102, but also offset the impact force generated by the lock tongue 102, thereby improving the service life of the lock tongue 102 and the locking plate 103.

[0083] The main structure of the device is made of high-strength anti-corrosion metal material, and the buffer pad 102-1 is made of high-strength, high-toughness, anti-ultraviolet, acid and alkali resistant, and corrosion resistant material to improve the overall mechanical strength and service life.

[0084] As shown in Figure 16 The locking base 101 is provided with a tight mounting top wire 101-2 for adjusting the lock tongue 102 and the locking plate 103 respectively. The locking base 101 can be provided with six tight mounting top wires 101-2, two of which are matched with the locking plate 103 for adjusting the pressing and holding force of the locking plate 103, and the other four are matched with the lock tongue 102 for adjusting the pressing and holding force of the lock tongue 102.

[0085] The tight mounting top wire 101-2 can simultaneously prolong the working life of the locking plate 103, the lock tongue 102 and the buffer pad 102-1, reduce the maintenance time and period, and maximize the production efficiency.

[0086] The rotating handle 104 includes a handle and a rotating screw rod 104-1, and the handle is in spherical contact with the locking plate 103. The upper part of the rotating handle 104 is T-shaped (or butterfly-shaped, plum-shaped, etc.), and the pressing contact surface of the locking plate 103 is designed as a spherical surface. This structure has the functions of automatic centering and large contact surface, large rotating or sliding friction force, and vibration resistance. The spherical surface matching has higher anti-dropping property, and improves the overall reliability and safety of the first locking structure 1.

[0087] The locking base 101 is movably mounted with the lock tongue 102, the locking plate 103 and the rotating screw rod 104-1 through the shaft pin 101-1. The shaft pin 101-1 is in interference fit during installation, which increases the working strength and reliability. Moreover, the position corresponding to the tail end of the shaft pin 101-1 on the locking base 101 is a through hole end face, which is convenient for replacement and improves the maintenance efficiency. The specification of the shaft pin 101-1 can be adaptively selected according to the requirements of the installed components.

[0088] The shaft pin 101-1 used when installing the screw rod is a hexagonal bolt 305, which facilitates replacement of the screw rod, saves maintenance time, and improves maintenance efficiency. Moreover, a plug 104-3 is arranged at the tail end through hole of the shaft pin 101-1, and the plug 104-3 is used to seal the end face, achieving the effect of dust and water prevention.

[0089] The locking plate 103 presses the lock tongue 102, the locking plate 103 is screwed by the screw handle 104, and the lock tongue 102 and the locking plate 103 are respectively limited by the shaft pin 101-1 used for installation, so as to ensure that the first locking structure 1 is reliable in locking when resisting high-strength vibration.

[0090] When it is necessary to open the lock tongue 102, the screw handle 104 is rotated to move upward along the screw rod 104-1, the screw handle 104 is rotated to one side after moving away from the locking plate 103 at one end, the locking plate 103 is no longer limited at this time, the locking plate 103 is flipped to one side away from the screw handle 104, the lock tongue 102 is no longer pressed, and then the lock tongue 102 can be flipped, so that the lock tongue 102 no longer plays a limiting role.
