Description

Technical Field

[0001] The invention belongs to the field of high-voltage fuses, and in particular relates to an upright high-voltage fuse shell sand filling device. Background Art

[0002] In the high-voltage electrical industry, the sand filling process of high-voltage fuses mostly relies on traditional manual operation, that is, by properly knocking on multiple points on the side of the high-voltage fuse shell, the sand is compacted and uniformed. This method is not only inefficient, but also difficult to ensure uniformity and density during the sand filling process due to manual operation, which often results in the density failing to meet the preset standards.

[0003] At present, some automatic sand filling mechanisms have appeared on the market. They tilt the high-voltage fuse housing (length greater than 1 meter) and in this state, use a vibration device to continuously vibrate and compact the sand filled into the high-voltage fuse housing.

[0004] However, in the specific sand filling practice of the above-mentioned mechanism, the staff found that continuous vibration could not ensure good compactness of the sand particles in the high-voltage fuse housing, and could not meet the higher application indicators of the high-voltage fuse. As a result, the service life of the high-voltage fuse filled with sand using an automatic sand filling mechanism was not as good as that of the high-voltage fuse filled with sand manually. Summary of the invention

[0005] In view of the deficiencies in the prior art, the inventors have conducted in-depth research and found that after the placed high-voltage fuse is filled with sand, the sand at different heights have different potential energies, resulting in different vibration amplitudes and frequencies required for compaction with the sand as a whole, especially for longer high-voltage fuses, and continuous vibration is applied to the sand as a whole, that is, the sand with different potential energies are given the same vibration amplitude and frequency, which leads to the mismatch between the sand at certain potential energy positions and the vibration amplitude and frequency, and the corresponding sand cannot be well compacted with the sand as a whole. The present invention provides an upright high-voltage fuse shell sand filling device, which adopts the upright sand filling form + water flow control mode to fill the high-voltage fuse shell with sand multiple times, and each time the sand is filled, the sand at different potential energies in the high-voltage fuse shell matches different vibration frequencies, thereby meeting the higher application indicators of the high-voltage fuse well and significantly improving the service life of the high-voltage fuse.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The upright high-voltage fuse shell sand filling device of the present invention comprises a sand storage container, a sand filling valve, a positioning unit and a plurality of knocking units, the positioning unit is used to vertically position the shell to be filled with sand, the sand storage container fills sand into the shell to be filled with sand through the sand filling valve, the knocking unit comprises a reciprocating drive assembly, the plurality of reciprocating drive assemblies are located at a plurality of predetermined height positions, the reciprocating drive assembly comprises a knocking actuator, the sand filling valve and the positioning unit are used as a flow sand filling mechanism, a predetermined volume of sand is filled into the shell to be filled with sand, and then the ready shell is arranged in the flow sand filling mechanism, the flow sand filling mechanism flows through the vicinity of each knocking unit in turn, and stays for a predetermined time near each knocking unit, when the predetermined time is reached, the sand storage container fills the predetermined volume of sand into the shell to be filled with sand through the sand filling valve A fixed volume of sand particles is formed, and at the same time, the knocking actuator continuously knocks on the circumference of the shell to be filled with sand, and the moving direction of the knocking actuator is perpendicular to the shell to be filled with sand. It can be seen that the circulation sand filling mechanism flows through the vicinity of the knocking unit in sequence, which is easy to be realized by the water flow control method, and the knocking frequency can be changed by only changing the reciprocating motion frequency of the knocking actuator, that is, different matching frequencies can be applied to the sand in the high-voltage fuse shell. Therefore, the present invention adopts the upright sand filling form + water flow control method to fill the high-voltage fuse shell with sand for multiple times, and each time the sand is filled, the sand at different potential energies in the shell to be filled with sand matches different vibration frequencies, thereby meeting the higher application indicators of the high-voltage fuse well and significantly improving the service life of the high-voltage fuse.

[0019] 2. Because the reciprocating drive assembly of the present invention includes a drive motor, a drive flywheel, a drive slider, a linkage shaft pin and a knocking actuator, the multiple drive motors of the multiple reciprocating drive assemblies have multiple motor speeds, the drive motor has a vertical output shaft, the drive flywheel is coaxially arranged on the output shaft, and the drive flywheel is formed with a drive through hole located near its own edge, the drive slider is formed with a horizontally extending linkage long through hole, the linkage shaft pin is simultaneously arranged in the drive through hole and the linkage long through hole, and the linkage shaft pin can move horizontally in the linkage long through hole, the knocking actuator is coupled to the drive slider, and the drive The movable slider is used to drive the knocking actuator to move back and forth horizontally, and the moving direction is perpendicular to the extension direction of the linkage long through hole. When the driving motor drives the driving flywheel to rotate, the driving flywheel drives the linkage shaft pin to move horizontally in the linkage long through hole. At the same time, the linkage shaft pin drives the driving slider to move back and forth horizontally along multiple knocking actuators, and the moving direction is perpendicular to the extension direction of the linkage long through hole. Therefore, the reciprocating drive mechanism of the present invention has a relatively compact structure and the speed adjustment of the driving motor is more precise, so that the frequency of the reciprocating knocking of the knocking actuator on the surface of the sand shell to be filled can be more accurately controlled.

[0020] 3. Because the knocking actuator of the present invention has a knocking part for knocking the circumferential surface of the shell to be filled with sand, the knocking part includes a knocking reference entity, a knocking force spring, an elastic force adjustment nut and a knocking head, the knocking reference entity is a rectangular body extending parallel to the linkage long through hole, the elastic force adjustment nut and the knocking force spring are respectively located on the opposite sides of the knocking reference entity, the elastic force adjustment nut locks the knocking force spring to adjust the elastic force of the knocking force spring, the knocking head has a flange structure, the flange structure has a knocking profile, the two ends of the knocking force spring are respectively abutted between the flange structure and the knocking reference entity, the knocking profile is perpendicular to the moving direction of the knocking actuator, and the knocking head knocks the circumferential surface of the shell to be filled with sand through the knocking profile. Therefore, the present invention can adjust the size of the knocking force of the knocking profile on the high-voltage fuse shell by adjusting the elastic force of the knocking force spring, thereby adjusting the vibration amplitude applied to the surface of the high-voltage fuse shell.

[0021] 4. Because the sand filling valve of the present invention includes a valve core tube, a valve body sleeve and a compression spring, the valve core tube has a straight tube portion and a plugging portion which are continuous in the vertical direction, the straight tube portion has a sand passing channel, the sand passing channel forms a sand passing port open to the outside, the sand passing port is located near the plugging portion, and the sand passing port is connected to the sand storage container through the sand passing channel, and the horizontal cross-sectional area of ​​the plugging portion is larger than that of the straight tube portion, the valve body sleeve is sleeved on the outside of the valve core tube, and a downward valve mouth is formed at the bottom of the valve body sleeve, and a guide channel and a plugging inner flange are formed in sequence from top to bottom inside the valve body sleeve, the guide channel is vertical and the valve core tube is inserted in the guide channel in cooperation, the plugging inner flange forms a plugging neck, the straight tube portion is inserted in the plugging neck, the upper surface of the plugging portion seals the plugging neck, and the valve core tube The valve body sleeve is elastically connected to the valve body sleeve in the vertical direction by a compression spring. When the valve body sleeve is vertically moved upward by an external force, the inner sealing flange moves away from the plugging head, so that the sand passing port is opened to the outside through the valve mouth; when the external force is removed, the compression spring causes the inner sealing flange to move toward the plugging head, so that the plugging head closes the sealing neck, that is, only when the valve body sleeve moves relative to the valve core tube and the plugging head no longer closes the sealing neck, can the sand filling valve realize sand filling into the high-voltage fuse housing. Otherwise, the sealing neck is closed and the sand filling valve cannot fill sand into the high-voltage fuse housing. Therefore, the present invention only needs to vertically set the high-voltage fuse housing and lift the valve body sleeve to a predetermined height to control the progress or stop of sand filling, thereby avoiding sand leakage to the outside due to the start of sand filling at an inappropriate time during the upright process.

[0022] 5. Because the positioning unit of the present invention also includes a shell base, a reset spring and a self-fixing axis tooling, the shell positioning base is elastically arranged on the shell base along the vertical direction by the reset spring, and the self-fixing axis tooling includes a clamping hinge rod and a linkage hinge rod, one end of the clamping hinge rod is hinged on the shell base, and the two ends of the linkage hinge rod are respectively hinged on the middle part of the clamping hinge rod and the bottom of the shell positioning base, and the high-voltage fuse shell is vertically arranged on the shell positioning base by external force, and the shell positioning base is close to the shell base, and the other end of the clamping hinge rod vertically clamps the high-voltage fuse shell. Therefore, the present invention elastically arranges the shell positioning base relative to the shell base, so that the high-voltage fuse shell arranged on the shell positioning base can always be tightly pressed against the valve nozzle and coupled and connected, and at the same time, the high-voltage fuse shell can be clamped and vertically positioned by the self-fixing axis tooling.

[0023] 6. Because the shell fixing unit of the present invention also includes an end matching pad that is detachably embedded in the upper part of the shell positioning base, the upper surface of the end matching pad has a shell embedding blind hole of a predetermined diameter, and the shell embedding blind hole is used to fit the end of the high-voltage fuse shell. Therefore, the present invention can be suitable for positioning high-voltage fuse shells of various diameter specifications by selecting a variety of shell embedding blind holes with different end matching pads.

[0024] 7. Because the present invention also includes a valve mounting frame, which is arranged on the upper surface of the top bearing base plate, the sand filling valve is arranged on the valve mounting frame, the outer surface of the valve body sleeve is affixed with a sensing metal sheet, and the valve mounting frame is provided with an inductive proximity switch connected to the signal of the driving rodless cylinder. When the valve body sleeve moves upward to a predetermined position and the inductive proximity switch corresponds to the sensing metal sheet, the driving rodless cylinder stops moving. Therefore, the present invention is realized by the inductive proximity switch, and the high-voltage fuse housing lifts the valve body sleeve to a predetermined height to control the sand filling, otherwise the sand filling stops.

[0025] 8. Because the present invention also includes a conversion sleeve, a valve body connecting convex hole and a leakage-proof sand skirt are formed at the upper end of the conversion sleeve, and a shell connecting hole is formed at the lower end. The valve body connecting convex hole is inserted in cooperation on the top bearing base and is connected with the sand filling valve. The shell connecting hole is connected with the upper end of the high-voltage fuse shell. The leakage-proof sand skirt is located below the top bearing base. The leakage-proof sand skirt extends vertically and continuously closes around the valve body connecting convex hole. A leakage cavity is formed between the solid outer surface of the valve body connecting convex hole and the inner surface of the leakage sand skirt. A connecting channel that connects the valve body connecting convex hole and the shell connecting hole is formed inside the conversion sleeve. Therefore, the present invention receives the sand occasionally leaked from the valve mouth through the leakage cavity, thereby further preventing the leakage of sand to the outside during the sand filling process.

[0026] 9. Because the base plate assembly of the present invention also includes a horizontal fixed bearing base plate, there are multiple circulation sand filling mechanisms, and the multiple circulation sand filling mechanisms are arranged in a circular shape. The fixed bearing base plate, the bottom bearing base plate, the top bearing base plate and the multiple circulation sand filling mechanisms are coaxially arranged. The multiple knocking units are distributed on the concentric circles with the multiple circulation sand filling mechanisms, and the number of the knocking units is less than the circulation sand filling mechanisms. When they are in a predetermined time length, the knocking units correspond to the circulation sand filling mechanisms along the radial direction of the distribution circle. The circulation sand filling mechanism without a knocking unit is used as the initial workstation for setting the ready shell. When the multiple circulation sand filling mechanisms rotate in a full circle relative to the multiple knocking units, the ready shells at the initial workstation flow through different knocking units in turn to complete the complete sand filling, and return to the initial workstation for removal. Therefore, the present invention realizes the simultaneous assembly line sand filling operation of multiple high-voltage fuse shells, thereby greatly improving the work efficiency.

[0043] The base assembly 10 includes a fixed supporting base 11 , a bottom supporting base 12 , a middle supporting base 13 and a top supporting base 14 .

[0044] The fixed bearing base 11, the bottom bearing base 12, the middle bearing base 13 and the top bearing base 14 are all arranged horizontally, and the fixed bearing base 11, the bottom bearing base 12, the middle bearing base 13 and the top bearing base 14 are arranged in sequence from bottom to top in the vertical direction, and a plurality of sand-filled through holes (not shown in the drawings) are evenly formed along the circumference of the circumferential edge of the top bearing base 14.

[0055] like Figure 4 and Figure 5 As shown, the sand filling valve 30 includes a valve core tube 31 , a valve body sleeve, a compression spring 34 , a connecting ring 35 and a thrust bearing 36 .

[0056] The valve core tube 31 is fixedly inserted on the plug plate 22, and the top end of the valve core tube 31 passes through the plug plate 22 and is connected to the sand storage container C through a pipeline (not shown in the drawings). Specifically, the upper end of the valve core tube 31 is locked on the plug plate 22 by a nut washer, and the sand storage container C contains sand to be poured into the high-voltage fuse housing F, which is input to the valve core tube 31 through a pipeline.

[0057] The valve core tube 31 has a straight tube portion 311 and a plugging portion 312 which are continuous in the vertical direction. The straight tube portion 311 has a sand passing channel 311a, and the sand passing channel 311a forms a sand passing opening 311b which is open outward, and the sand passing opening 311b is located near the plugging portion 312, so that the sand passing opening 311b is connected to the sand storage container C through the sand passing channel 311a, and the horizontal cross-sectional area of ​​the plugging portion 312 is larger than that of the straight tube portion 311. Specifically, the straight tube portion 311 is in the shape of a vertical hollow tube, and the plugging portion 312 is in the shape of a truncated cone coaxial with the straight tube portion 311, and the bottom surface of the plugging portion 312 is at the bottom, so that the plugging portion 312 forms a flange at the bottom end of the straight tube portion 311.

[0058] The valve body sleeve is sleeved on the outside of the valve core tube 31 , and the valve body sleeve is suspended on the valve core tube 31 through the plugging portion 312 . The valve body sleeve includes an upper sleeve 32 and a lower sleeve 33 which are threadedly connected in the vertical direction.

[0059] The surface of the upper sleeve 32 has an inductive metal sheet 32a and a pin slot 32b.

[0060] The sensing metal sheet 32a is attached to the outer peripheral surface of the upper sleeve 32. When the valve body sleeve moves upward to a predetermined position, the sensing metal sheet 32a corresponds to the inductive proximity switch 211, and the inductive proximity switch 211 generates a trigger signal to drive the rodless cylinder 51 to stop moving.

[0061] The pin slot 32 b is vertical and formed at the top of the upper sleeve 32 , and the rotation limiting pin 221 is inserted into the pin hole of the insertion plate 22 and the pin slot 32 b at the same time, thereby limiting the rotational freedom of the valve body sleeve relative to the insertion plate 22 in the horizontal plane.

[0062] The upper end of the lower sleeve 33 is located inside the upper sleeve 32 and is threadedly connected. The end surface corresponding to the external thread of the lower sleeve 33 forms a horizontal abutting step surface 33 a relative to the inner wall of the upper sleeve 32 .

[0063] The lower sleeve 33 is formed with a guide channel 33b, a thick portion 33c, a blocking inner flange 33d and a valve mouth 33e which are sequentially arranged from top to bottom.

[0064] The guide channel 33b extends vertically and the straight tube portion 311 is inserted in the guide channel 33b. The thick portion 33c is a portion with a larger cross-section on the lower sleeve 33. The inner sealing flange 33d is formed on the inner wall corresponding to the thick portion 33c to form a sealing neck. The straight tube portion 311 is inserted in the sealing neck. The upper surface of the plugging portion 312 closes the sealing neck, so that the valve body sleeve is suspended on the valve core tube 31. In this embodiment, the inner sealing flange 33d has a flange end face extending in the vertical direction. When the upper surface of the plugging portion 312 closes the sealing neck, the flange end face closes the sand opening 311b.

[0065] The valve mouth 33e is vertically downward and corresponds to the sand filling hole. The sand storage container C fills sand into the high-voltage fuse housing F through the sand filling valve 30 via the valve mouth 33e. In this embodiment, the lower sleeve 33 includes a guide cylinder section 33f and a valve mouth 33e that are sequentially threaded in the vertical direction. The valve mouth 33e is located inside the guide cylinder section 33f, and the upper end of the valve mouth 33e is thicker, thereby forming a sealing inner flange 33d.

[0066] The two ends of the compression spring 34 respectively abut against the bottom surface of the top bearing base 12 and the abutment step surface 33a. When the valve body sleeve is moved vertically upward by external force, the inner sealing flange 33d moves away from the plugging head 312. When the sand passing port 311b is opened to the outside through the valve mouth 33e, the sensing metal sheet 32a just corresponds to the inductive proximity switch 211. When the external force is removed, the compression spring 34 causes the inner sealing flange 33d to move toward the plugging head 312, so that the plugging head 312 closes the sealing neck, and the sensing metal sheet 32a no longer corresponds to the inductive proximity switch 211.

[0067] The upper and lower ends of the connecting ring 35 are open, and the upper end is sleeved on the valve nozzle 33 e. The thrust bearing 36 is located inside the connecting ring 35, and the lower end of the connecting ring 35 is coupled to the rotating sleeve 40 through the thrust bearing 36.

[0068] like Figure 6 As shown, the upper end of the adapter sleeve 40 is formed with a valve body connecting convex hole 40a and a leakage-proof sand skirt 40b, and the lower end is formed with a shell connecting hole 40d. The valve body connecting convex hole 40a is connected to the valve mouth 33e through the thrust bearing 36, and the upper end of the high-voltage fuse shell F is connected to the shell connecting hole 40d, and the interior of the adapter sleeve 40 is formed with a connecting channel 40e that connects the valve body connecting convex hole 40a and the shell connecting hole 40d.

[0069] The anti-leakage sand skirt 40b extends vertically and surrounds the valve body connecting convex hole 40a and is continuously closed. A leakage cavity 40c is formed between the solid outer surface of the valve body connecting convex hole 40a and the inner surface of the leakage sand skirt 40b. When sand leakage occurs in the connecting ring 35, the sand falls into the interior of the leakage cavity 40c. Specifically, the valve body connecting convex hole 40a corresponds to the sand filling hole passing through the top bearing base 12, and the anti-leakage sand skirt 40b is located below the top bearing base 12.

[0070] like Figure 7 As shown, the positioning unit 50 includes a driving rodless cylinder 51, a driving motor 52, a housing base 53, a housing positioning base 54, a linear bearing 55, a guide slide support 56, a return spring 57, a self-fixing axis tooling 58 and an end matching pad 59.

[0071] The two ends of the driving rodless cylinder 51 are arranged on the bottom bearing base 12 and the middle bearing base 13, and have a vertically movable moving slider 511. The high-voltage fuse housing F is coupled and arranged on the moving slider 511. Specifically, when sand filling is performed, the moving slider 511 drives the high-voltage fuse housing F to move upward, and the valve body sleeve is pushed upward through the adapter sleeve 40. When the sensing metal sheet 32a of the valve body sleeve corresponds to the inductive proximity switch 211, the moving slider 511 stops moving, and at the same time, the sand storage container C starts to fill sand into the high-voltage fuse housing through the sand filling valve 30, and after the sand filling continues for a corresponding predetermined time, the moving slider 511 is driven to descend, thereby driving the high-voltage fuse housing F to move downward, so that the sensing metal sheet 32a no longer corresponds to the inductive proximity switch 211.

[0072] The driving motor 52 is arranged on the moving slider 511, and has a vertically upward output shaft (not shown in the drawings), and the output shaft is coaxially provided with a horizontal shell base 53. Specifically, the driving motor 52 is arranged on the moving slider 511 through a motor bracket S. When the moving slider 511 stops rising, the driving motor 52 starts to rotate through the control unit. After the driving motor 52 rotates for a corresponding predetermined period of time, the moving slider 511 descends. In this embodiment, the shell base 53 is coupled to the output shaft of the driving motor 52 through a driving thrust bearing.

[0073] The shell positioning base 54 is coupled with the shell base 53 in the vertical direction, and the shell positioning base 54 vertically corresponds to the sand-filled through-hole. The high-voltage fuse shell F is vertically arranged on the shell positioning base 54 and the upper end of the high-voltage fuse shell F is open. Specifically, the shell positioning base 54 is located above the shell base 53.

[0074] The shell positioning base 54 and the shell base 53 are coupled by a linear bearing 55 which is movable in the vertical direction, and the shell positioning base 54 is elastically set on the shell base 53 by a reset spring 57, and the reset spring 57 is sleeved on the outside of the linear bearing 55. Specifically, the lower end of the shell positioning base 54 has a vertical guide sliding pillar 56 which is inserted and fitted in the linear bearing 55, and the reset spring 57 is sleeved outside the guide sliding pillar 56. When the shell positioning base 54 and the shell base 53 are close to each other, the reset spring 57 is compressed to store energy; when the shell positioning base 54 and the shell base 53 are far away from each other, the energy stored in the reset spring 57 is restored.

[0075] The self-fixing axis tooling 58 includes a clamping hinge rod 581 and a linkage hinge rod 582. One end of the clamping hinge rod 581 is hinged to the upper end surface of the shell base 53, and the two ends of the linkage hinge rod 582 are respectively hinged to the middle part of the clamping hinge rod 581 and the bottom of the shell positioning base 54. The other end of the clamping hinge rod 581 is a free end.

[0076] The end matching pad 59 is detachably embedded in the upper end face of the shell positioning base 54. The upper surface of the end matching pad 59 has a shell embedding blind hole of a predetermined diameter (not shown in the drawings). The shell embedding blind hole is used to fit the end of the high-voltage fuse shell F. Specifically, the end matching pad 59 has a variety of different specifications to adapt to high-voltage fuse shells F of different diameters.

[0077] The high-voltage fuse housing F is inserted into the housing embedding blind hole, and then the housing positioning base 54 is moved closer to the housing base plate 53 by external force, and the free end of the clamping hinge rod 581 vertically clamps and positions the high-voltage fuse housing F.

[0078] like Figure 8As shown, there are multiple knocking units 60 , which are evenly distributed on the fixed supporting base 11 along the circumference of the fixed supporting base 11 .

[0079] The knocking unit 60 includes a knocking base frame 61 , a lifting assembly 62 , a moving assembly 63 , a reciprocating driving assembly 64 and a vibration buffer 65 .

[0080] The striking base 61 includes a base support plate 61 a , a base column 61 b ​​and a base linear bearing 61 c .

[0081] Specifically, the knocking base 61 includes at least two base plates 61a, multiple base columns 61b and multiple base linear bearings 61c. The multiple base plates 61a are arranged in the vertical direction and are all arranged horizontally. The uppermost base plate 61a is movable in the vertical direction. Multiple base columns 61b are arranged on the base plate 61a. Multiple base linear bearings 61c are arranged on other base plates 61a. When the base plate 61a moves in the vertical direction, the base columns 61b are vertically guided by the base linear bearings 61c. In this embodiment, the number of base plates 61a is three, and each of the two base plates 61a located in the middle is provided with four base linear bearings 61c. There are four base columns 61b, which can be vertically moved relative to the fixed bearing base 11 through the base linear bearings 61c, and all pass through the fixed bearing base 11.

[0082] like Fig. 9 As shown, the lifting assembly 62 includes a lifting motor 621 and a lifting drive worm 622 .

[0083] Specifically, the lifting motor 621 and the lifting drive worm 622 are fixed on the upper end surface of the non-top base support plate 61a, the lifting motor 621 has an output turbine rod 621a formed on the output shaft, the lifting drive worm 622 extends vertically and is connected to the bottom of the upper base support plate 61a, the output turbine rod 621a and the lifting drive worm 622 form a turbine worm transmission mechanism, so that when the lifting motor 621 is actuated, the lifting drive worm 622 will rise or fall on the upper base support plate 61a.

[0084] like Fig.10 As shown, the moving assembly 63 enables the reciprocating driving assembly 64 to be movably disposed on the striking platform, specifically, the striking platform is the upper surface of the base support plate 61a located at the top.

[0085] Specifically, the moving assembly 63 includes a moving motor 631 , a carrying slide 632 , a limit sensor 633 and an in-position sensor 634 .

[0086] The mobile motor 631 is arranged on the knocking platform and has a horizontally extending screw output shaft (not shown in the accompanying drawings). The supporting slide 632 is movably clamped on the knocking platform through the cooperation of guide rails and guide shoes, and the supporting slide 632 is threadedly cooperated with the screw output shaft to form a screw slider mechanism. The limit sensor 633 is fixed on the knocking platform to limit the extreme travel position of the screw slider mechanism. The in-position sensor 634 is fixed on the side of the knocking platform to determine whether the knocking unit 60 corresponds to the flow sand filling mechanism 50a along the radial direction of the distribution circle. When corresponding, the flow sand filling mechanism 50a stays for a predetermined period of time.

[0087] like Fig.11 and Fig.12 As shown, the reciprocating drive assembly 64 is movably arranged on the knocking platform through the moving assembly 63, including a driving base part 641, a driving motor 642, and a driving flywheel 643, a reciprocating linear bearing 644, a driving slider 645, a linkage shaft pin 646 and a knocking actuator 647 all located inside the driving base part 641.

[0088] Multiple driving motors 642 have multiple motor speeds. The driving motor 642 has an output shaft that vertically penetrates the driving base part 641. The driving flywheel 643 is coaxially arranged on the output shaft, and the driving flywheel 643 is formed with a driving through hole 6431 located near its own edge. The driving slider 645 is formed with a linkage long through hole 6451 that is perpendicular to the movement direction of the knocking actuator and extends horizontally. The linkage shaft pin 646 is simultaneously arranged in the driving through hole 6431 and the linkage long through hole 6451, and the linkage shaft pin 646 can move horizontally in the linkage long through hole 6451, and the moving direction is perpendicular to the extension direction of the linkage long through hole 6451. Specifically, the linkage shaft pin 646 is provided with a movable bearing 6461 through a shaft sleeve (not shown in the drawings), so that when the linkage shaft pin 646 moves in the linkage long through hole 6451, the outer ring surface of the movable bearing 6461 maintains rolling friction with the inner wall of the linkage long through hole 6451.

[0089] When the driving motor 642 drives the driving flywheel 643 to rotate, the driving flywheel 643 drives the linkage shaft pin 646 to move horizontally in the linkage long through hole 6451, and at the same time, the linkage shaft pin 646 drives the driving slider 645 to move horizontally along the radial reciprocating circle of the distribution circle of multiple knocking units 60. The knocking actuator 647 is arranged on the driving slider 645, so as to realize the horizontal reciprocating movement of the knocking actuator 647. When it is in a predetermined time length, the sand storage container C fills sand into the shell F to be filled with sand through the sand filling valve 30. At the same time, the knocking actuator 647 forms a continuous knocking on the circumference of the shell F to be filled with sand through reciprocating movement, and the moving direction of the knocking actuator is perpendicular to the shell to be filled with sand. Specifically, the knocking actuator 647 includes a moving rod portion (not shown in the accompanying drawings) that cooperates with the reciprocating linear bearing 644, and the knocking actuator 647 is linearly guided by the reciprocating linear bearing 644.

[0090] The end of the knocking actuator 647 facing the flow sand filling mechanism 50a has a knocking part (not shown in the drawings), which is used to knock the circumferential surface of the shell F to be filled with sand, and includes a knocking reference entity 647a, a knocking force spring 6471, an elastic force adjustment nut 6472 and a knocking head 6473.

[0091] The knocking part is elastically arranged on the knocking reference entity 647a through the knocking force spring 6471. The knocking reference entity 647a is a rectangular body extending parallel to the linkage long through hole 6451, and the knocking reference entity 647a is fixed on the moving rod. The elastic force adjustment nut 6472 and the knocking force spring 6471 are respectively located on the opposite sides of the knocking reference entity 647a, and the elastic force adjustment nut 6472 locks the knocking force spring 6471 to adjust the elastic force of the knocking force spring 6471.

[0092] The striking profile 6473a is an end face of a flange structure of the striking head 6473, which is perpendicular to the moving direction of the striking actuator 647. The two ends of the striking force spring 6471 are respectively abutted between the flange structure and the striking reference entity 647a, and the striking profile 6473a is perpendicular to the moving direction of the striking actuator 647. The striking head 6473 strikes the peripheral surface of the sand shell F to be filled through the striking profile 6473a, so that the striking head 6473 strikes the peripheral surface of the sand shell F to be filled through the striking profile 6473a. 473a knocks on the circumferential surface of the high-voltage fuse shell F. Specifically, the knocking head 4371 is penetrated on the knocking reference entity 647a, and the knocking head 4371 has an external threaded end that cooperates with the elastic force adjustment nut 6472, and the two ends of the knocking force spring 6471 are respectively abutted between the flange structure and the knocking reference entity 647a, so as to adjust the elastic force of the knocking force spring 6471, that is, adjust the reaction force of the knocking surface 6473a after the impact, that is, adjust the impact force.

[0093] The vibration buffer 65 includes a vibration transmission frame 651 and a pneumatic buffer 652 .

[0094] Specifically, the lifting motor 621 is fixed on the upper end surface of the non-top base plate 61a through the vibration transmission frame 651, and the pneumatic buffer 652 is fixed on the vibration transmission frame 651, and the piston output end of the pneumatic buffer 652 maintains a slight contact with the base column 61b. When the base 61 is struck and vibrates due to the striking reaction force of the striking surface 6473a, the pneumatic buffer 652 promptly transmits the vibration to the outside through the base column 61b and the fixed bearing base 11.

[0095] Specifically, in the process that the circulating sand filling mechanism 50a flows through each knocking unit 60 in sequence, each time the circulating sand filling mechanism 50a is in a stationary state, the control unit controls the positioning unit 50 to drive the rodless cylinder 51 and the rotating motor 52 to rotate and lift the high-voltage fuse housing F for a predetermined time. During this predetermined time, the sand filling valve 30 is opened due to being lifted, and sand is filled into the high-voltage fuse housing F; at the same time, the control unit controls the knocking unit 60 to continuously knock the actuator 647 on the circumference of the rotating high-voltage fuse housing F. Knocking; when the preset time is over, the control unit controls the positioning unit 50 to stop the driving motor 52 and reversely drive the rodless cylinder 51 to make the high-voltage fuse housing F stop and descend, and the sand filling valve 30 is restored to be closed, and the sand is stopped from being filled into the high-voltage fuse housing F; at the same time, the control unit controls the knocking unit 60 to stop the reciprocating movement of the knocking actuator 647, and when the circulating sand filling mechanism 50a circulates back to the corresponding position of the non-knocking unit 60, the high-voltage fuse housing F has completed the sand filling, and the operator removes the high-voltage fuse housing F.

[0096] In this embodiment, there are multiple control units, 11 knocking units 60, and 12 flow sand filling mechanisms 50a, that is, the upright high-voltage fuse shell sand filling equipment 100 can simultaneously perform flow and parallel sand filling on 12 shells F to be filled with sand.

[0097] The above-mentioned implementation modes are preferred cases of the present invention and are not used to limit the protection scope of the present invention.
