Description

Technical Field

[0001] The present application relates to the technical field of screening machine walking beams, and in particular to a quick-detachable modular walking side beam and a crushing screening machine thereof. Background Art

[0002] In mining, building demolition, road construction and other engineering fields, crushing and screening machines are core equipment for material crushing and grading. Their walking side beams are the structure that supports the weight of the entire machine and ensures the movement and stability of the equipment. The structure of the walking side beams often directly affects the operating efficiency, adaptability and maintenance difficulty of the equipment.

[0003] For related technologies of walking side beams, please refer to the Chinese patent with publication number CN204623600U, which discloses a crawler walking system, a mobile screening station and a mobile crushing station, wherein the crawler walking system includes a main frame, a detachable connecting structure and a crawler, wherein the main frame is provided with at least one first mounting surface, the crawler includes a crawler beam, and the crawler beam is provided with at least one second mounting surface, and the first mounting surface and the second mounting surface are detachably fixedly connected via a detachable connecting structure. Both the mobile screening station and the mobile crushing station include the above-mentioned crawler walking system. The first mounting surface on the main frame and the second mounting surface on the crawler beam are connected by a detachable connecting structure, so that the main frame and the crawler are detachable, thereby realizing the detachability of the entire crawler walking system, facilitating the assembly and maintenance of the crawler walking system, and thus affecting the use of the hydraulic motor, thereby causing inconvenience to its users.

[0004] In the process of implementing this application, the inventors discovered that the prior art has the following problems:

[0005] The traveling system of a crushing and screening machine usually adopts an integrated crawler beam structure, including crawler beams, drive motors, drive wheels, supporting rollers, guide wheels, sprocket roller seats and other components, which are fixed together by welding or high-strength bolts. However, different engineering scenarios have different requirements for the operating width and load-bearing capacity of crushing and screening machines. Therefore, the integral side beam cannot be flexibly adjusted in size according to demand, and needs to be disassembled as a whole for maintenance or replacement, which increases the difficulty and time cost of maintenance. In addition, complex connection structures are used to improve stability, but this often leads to increased weight and increased manufacturing costs. Some existing modular design attempts aim to improve the convenience of maintenance, but due to the complexity of the connection structure, they often fail to achieve the expected convenience effect, but instead increase weight and cost. Summary of the Invention

[0006] The purpose of this application is to provide a quick-detachable modular walking side beam and a crushing and screening machine thereof.

[0007] In the first aspect, the present application provides a quick-detachable modular walking side beam, which adopts the following technical solution:

[0008] A quick-release modular walking side beam comprises a vehicle frame, a vehicle chassis and a walking mechanism, wherein the vehicle chassis is mounted below the vehicle frame by bolts, and the walking mechanism is mounted on both sides of the vehicle chassis, and the walking mechanism comprises a main support U-shaped frame and a quick-release support assembly, and quick-release support assemblies are provided on both sides of the main support U-shaped frame.

[0010] The walking mechanism also includes a crawler track, a driving wheel, a driving assembly and a guide wheel, and the inner wall of the crawler track is provided with a driving wheel, and the guide wheel is placed on the side of the driving wheel. The driving wheel is driven by the driving assembly, and the driving wheel is installed on the driving shaft of the driving assembly. When the driving assembly drives the driving wheel to rotate along the axis, the driving wheel drives the guide wheel to rotate through the crawler track.

[0011] The first secondary support U-shaped frame is respectively provided with a first secondary support U-shaped frame on one side of the main support U-shaped frame away from the driving assembly, and the main support U-shaped frame and the first secondary support U-shaped frame form a detachable structure through a walking mechanism and a locking bolt, and a detachable structure is formed between the first secondary support U-shaped frame and the guide wheel through a circular connecting ring and a locking bolt, and a detachable structure is formed between the second secondary support U-shaped frame and the driving wheel through a circular connecting ring and a locking bolt, and a detachable structure is formed between the second secondary support U-shaped frame and the driving wheel through a bearing, and supporting wheels are provided under the main support U-shaped frame, and shaft holes are symmetrically provided on both sides of the bottom of the second secondary support U-shaped frame, and the wheel axles of the supporting wheels pass through the shaft holes and are axially limited by retaining springs;

[0012] A wear-resistant bushing is provided on the contact surface between the shaft hole and the wheel axle, and the wear-resistant bushing is fixed in the shaft hole through interference fit.

[0013] By adopting the above technical solution, the main support U-frame, the first secondary support U-frame and the second secondary support U-frame are all made of high-strength aluminum alloy. The high strength and low weight of the aluminum alloy itself, and the bending rigidity are improved by the U-shaped cross-section design, so as to reduce the overall weight of the mechanical equipment and meet the lightweight requirements of the mobile screening machine. In addition, at the multi-hole bolt connection provided at the fastening frame of the vehicle chassis, alloy steel bolts are used and a double-bolt locking structure is adopted. The double-bolt locking structure is arranged according to the load distribution. The problem of bolt detachment is reduced by the locking structure of the double bolts themselves, thereby maintaining the connection strength of the structure and the redundant weight brought by the frame of the equipment itself.

[0015] By adopting the above technical solution, the hydraulic telescopic function of the quick-release support assembly can adjust the height difference between the first support base and the second support base through the hydraulic rod to adapt to uneven ground or soft foundation conditions, and the six sets of positioning holes and limit connecting rods can lock the support position to prevent equipment displacement.

[0016] The driving assembly includes a hydraulic motor reducer and a quick-release hydraulic motor, and the quick-release hydraulic motor is installed below the hydraulic motor reducer, and the quick-release hydraulic motor is installed below the hydraulic motor reducer.

[0017] By adopting the above technical solution, the hydraulic motor reducer cooperates with the quick-release hydraulic motor to provide stable torque output, adapting to the normal working conditions of crawler walking, maintaining the normal working state of the crawler while reducing the original structural design and weight, and both are connected to the second auxiliary support U-shaped frame. The quick-release hydraulic motor can be separated by disassembling the second auxiliary support U-shaped frame, so that the drive wheel can be separated from the standardized interface of the quick-release hydraulic motor through the quick-release hydraulic motor structure, supporting plug and play, and shortening the time for emergency maintenance.

[0018] The side of the quick-release support assembly is connected to a drive box, and the drive box includes a driving shaft, a driving frame, a screw and a driving motor, and the driving frame is installed at the end of the driving shaft away from the quick-release support assembly, and the screw is placed inside the driving frame, and the driving motor is installed at the end of the screw away from the driving shaft.

[0019] By adopting the above technical solution, the driving shaft and screw in the drive box cooperate with the drive motor to fine-tune the height of the crawler track and the ground. The chain can be lifted for maintenance. When the equipment is stationary or parked, the quick-release support assembly can be extended through the drive box and adjusted to contact the ground using a hydraulic rod, providing additional stable support for the equipment, thereby sharing the load of the walking mechanism.

[0020] A pushing groove is provided at the top of the driving box, and a limiting connecting rod is provided between the limiting hole and the pushing groove, and a sliding structure is formed between the quick-release support assembly and the driving box through the limiting hole, the pushing groove and the limiting connecting rod.

[0021] By adopting the above technical solution, a limiting connecting rod is fixedly installed in the limiting hole provided in the quick-release support assembly. When the quick-release support assembly is pushed to move by the driving motor and the screw rod, the limiting connecting rod in the placement groove can support the quick-release support assembly, thereby ensuring stable operation of the quick-release support assembly.

[0022] On the second aspect, the present application provides a crushing and screening machine, including the above-mentioned quick-release modular walking side beam, the vehicle frame includes a mounting plate, a placement groove and a side baffle, and a placement groove is reserved at the top of the mounting plate, and the side of the placement groove is installed with a side baffle by bolts.

[0023] The vehicle chassis comprises a fastening frame, a positioning rod and a connecting frame, wherein the positioning rod is arranged below the fastening frame, and the connecting frame is installed on a side of the positioning rod away from the fastening frame.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The main support U-shaped frame is connected to the first and second auxiliary support U-shaped frames using multi-hole high-strength bolts and is assembled with circular connecting rings, drive wheels, and guide wheels. In case of damage, only partial modules need to be disassembled and replaced, without the need for overall replacement. When separation is required, quick separation can be achieved by removing the corresponding second auxiliary support U-shaped frame without dismantling the entire structure, shortening replacement time. Quick-release support components can also be used to assist in disassembly, reducing the total cost of parts replacement and maintenance, thereby ensuring stable operation of the equipment.

[0027] 2. The main support U-shaped frame, the first secondary support U-shaped frame and the second secondary support U-shaped frame are all made of high-strength aluminum alloy. The high strength and low weight of aluminum alloy itself, and the U-shaped cross-section design improves the bending rigidity to reduce the overall weight of the mechanical equipment and meet the lightweight requirements of the mobile screening machine. In addition, the multi-hole bolt connection provided at the fastening frame of the chassis adopts a double-bolt locking structure by using alloy steel bolts and arranged according to the load distribution. The double-bolt locking structure and the locking structure of the double bolts themselves can reduce the problem of bolt detachment, thereby maintaining the connection strength of the structure and avoiding the redundant weight brought by the equipment frame itself affecting the replacement of parts.

[0028] 3. The hydraulic telescopic function of the quick-release support assembly adjusts the height difference between the first support base and the second support base through the telescopic hydraulic rod, so that the second support base can fit the uneven ground or sunken soft foundation, ensuring the stability of the equipment during use, and the six groups of positioning holes distributed in a linear array cooperate with the limit connecting rod to lock the support height after the hydraulic rod is extended and retracted to prevent horizontal deviation of the equipment during operation; when the hydraulic rod pushes the second support base downward to abut the ground, the reaction force generated by the ground is transmitted to the first support base through the second support base, driving the first auxiliary support U-shaped frame and the second auxiliary support U-shaped frame fixedly connected to it to move upward synchronously, thereby lifting the crawler off the ground, facilitating quick maintenance of the crawler chain links or walking mechanism; when the equipment is stationary or parked, the drive box pushes the quick-release support assembly horizontally to the side of the crawler, and the hydraulic rod extends to make the second support base contact the ground. At this time, the support assembly forms a triangular stable structure, providing additional support for the equipment, which can effectively share the load borne by the walking mechanism.

[0038] The following is combined with Figure 1 - Attachment Figure 8 , and further explain this application in detail.

[0039] Example 1: A quick-release modular walking side beam, including a vehicle frame 1, a vehicle chassis 2 and a walking mechanism 3. The vehicle chassis 2 is installed below the vehicle frame 1 by bolts, and the walking mechanism 3 is installed on both sides of the vehicle chassis 2. The walking mechanism 3 includes a main support U-shaped frame 305 and a quick-release support component 309, and quick-release support components 309 are provided on both sides of the main support U-shaped frame 305. The main support U-shaped frame 305 adopts a multi-hole high-strength method in the process of connection with the first auxiliary support U-shaped frame 306 and the second auxiliary support U-shaped frame 307. The bolts are used in conjunction with the circular connecting ring to assemble with the driving wheel 302 and the guide wheel 304. When damaged, only the local module needs to be disassembled and replaced, and there is no need to replace the entire unit. The hydraulic motor reducer 3012 is connected to the driving wheel 302 by fastening bolts. When separation is required, quick separation can be completed by removing the corresponding second auxiliary support U-shaped frame 307. There is no need to dismantle the entire structure, which shortens the replacement time. The quick-release support assembly 309 can also be used to assist in dismantling, reducing the total cost of replacing and maintaining parts, thereby achieving stable operation of the equipment.

[0040] The walking mechanism 3 also includes a crawler track 301, a driving wheel 302, a driving assembly 303 and a guide wheel 304. The driving wheel 302 is provided on the inner wall of the crawler track 301, and the guide wheel 304 is placed on the side of the driving wheel 302. The driving wheel 302 is driven by the driving assembly 303, and the driving wheel 302 is installed on the driving shaft of the driving assembly 303. When the driving assembly 303 drives the driving wheel 302 to rotate along the axis, the driving wheel 302 drives the guide wheel 304 to rotate through the crawler track 301.

[0041] The first auxiliary support U-shaped frame 306 and the second auxiliary support U-shaped frame 307 are respectively provided on the side of the main support U-shaped frame 305 away from the driving assembly 303, and the main support U-shaped frame 305 and the first auxiliary support U-shaped frame 306 form a detachable structure through the walking mechanism 3 and the locking bolts, and the first auxiliary support U-shaped frame 306 and the guide wheel 304 form a detachable structure through a circular connecting ring and a locking bolt, a bearing is installed on the rotating shaft of the guide wheel 304, and a circular connecting ring is sleeved on the bearing, and the first auxiliary support U-shaped frame 306 is connected to the circular connecting ring by using a locking bolt, thereby completing the fixation between the first auxiliary support U-shaped frame 306 and the guide wheel 304, and the locking bolt used has a double-bolt locking structure and a reverse thread method, which has a relief effect on the bolt falling off caused by vibration, thereby protecting the connection between the two, and a supporting wheel 308 is provided below the main support U-shaped frame 305, and the bottom of the second auxiliary support U-shaped frame 307 Axial holes 3010 are symmetrically provided on both sides, and the axles of the supporting wheels 308 pass through the axle holes 3010 and are axially limited by retaining springs. The contact surface between the axle hole 3010 and the axle is provided with a wear-resistant bushing 3011, and the wear-resistant bushing 3011 is fixed in the axle hole 3010 by interference fit. The main support U-shaped frame 305, the first secondary support U-shaped frame 306 and the second secondary support U-shaped frame 307 are all made of high-strength aluminum alloy. The high strength and low weight of the aluminum alloy itself, and the U-shaped cross-section design to improve the bending rigidity, can reduce the overall weight of the mechanical equipment and meet the lightweight requirements of the mobile screening machine. In addition, at the multi-hole bolt connection provided at the fastening frame 201 of the vehicle chassis 2, alloy steel bolts are used and a double-bolt locking structure is adopted. They are arranged according to the load distribution. The double-bolt locking structure and the locking structure of the double bolts themselves can reduce the problem of bolt detachment, thereby maintaining the connection strength of the structure and the redundant weight brought by the frame of the equipment itself.

[0042] The quick-release support assembly 309 includes a first support base 4, a second support base 5, a positioning hole 7 and a hydraulic rod 8, and the second support base 5 is provided below the first support base 4, and four groups of limiting holes 6 are provided on both sides of the first support base 4, and the four groups of limiting holes 6 have the same aperture, and positioning holes 7 are provided on both sides of the second support base 5, and there are six groups of positioning holes 7, and the six groups of positioning holes 7 are distributed in a straight line array along the center line of the first support base 4, and a hydraulic rod 8 is placed inside the first support base 4, and the first support base 4 and the second support The bases 5 are connected by a hydraulic rod 8 to form a retractable structure. The quick-release support assembly 309 injects high-pressure oil into the rodless cavity of the hydraulic cylinder through the balance valve via the hydraulic pump of the hydraulic rod 8. The piston is pushed outward by the oil pressure, and the piston rod is extended outward. At this time, the oil in the rod cavity returns to the oil tank through the return oil pipeline, thereby pushing the second support base 5 away from the first support base 4 and making the second support base 5 contact the ground. At this time, the hydraulic rod 8 is in use and bears the weight of the equipment, and the balance valve connected to the hydraulic rod 8 adjusts the oil to prevent the load from sliding down due to its own weight when the hydraulic rod 8 is driven. After the hydraulic rod 8 is extended to the full position, the balancing valve can maintain the pressure of the oil circuit to prevent the reverse flow of the hydraulic rod 7 from being pressed back. When the hydraulic rod 8 is reset, the balancing valve switches the oil circuit, and the high-pressure oil enters the rod chamber, pushing the piston to move in the opposite direction, the piston rod retracts, and the oil in the rodless chamber returns. In addition, the balancing valve provided at the oil inlet end of the hydraulic rod 8 cooperates with the overflow valve connected to the balancing valve to protect the hydraulic rod 8 from overload. The height difference between the first and second support bases 5 is adjusted by the hydraulic rod 8 to adapt to uneven ground or soft foundation conditions. In addition, the six groups of positioning holes 7 and the limit connecting rod 14 The support position can be accurately locked to prevent the equipment from shifting. At the same time, the quick-release support assembly 309 can also be used to lift the height of one side of the track 301 to separate the track 301 from the ground during equipment maintenance, thereby facilitating equipment maintenance. While supporting through the quick-release support assembly 309, the positioning shaft can be passed through the positioning hole 7 in the second support base 5 and connected to the connecting hole of the track 301, thereby limiting the track 301 to facilitate the restriction of the track 301 and prevent the track 301 from being on the slope for a long time.

[0043] The drive assembly 303 includes a hydraulic motor reducer 3012 and a quick-release hydraulic motor 3013. The quick-release hydraulic motor 3013 is installed below the hydraulic motor reducer 3012. The output shaft of the hydraulic motor reducer 3012 is connected to the drive shaft of the drive wheel 302 through a quick-release interface. The hydraulic motor reducer 3012 is fixedly installed on the second secondary support U-shaped frame 307. The hydraulic motor reducer 3012 cooperates with the quick-release hydraulic motor 3013 to provide torque output, adapting to the original working conditions of the crawler 301. While reducing the original structural design and weight, the normal working state of the crawler 301 is maintained. Both are connected to the second secondary support U-shaped frame 307. The quick-release hydraulic motor 3013 can be separated by disassembling the second secondary support U-shaped frame 307, so that the drive wheel 302 can be separated from the standardized interface of the quick-release hydraulic motor 3013 through the quick-release hydraulic motor 3013 structure, supporting plug-and-play, and shortening the time for emergency maintenance.

[0044] The side of the quick-release support assembly 309 is connected to a drive box 9, and the drive box 9 includes a driving shaft 11, a driving frame 12, a screw 13 and a driving motor 10, and the driving shaft 11 is installed at the end away from the quick-release support assembly 309 with the driving frame 12, and the screw 13 is placed inside the driving frame 12, and the driving motor 10 is installed at the end of the screw 13 away from the driving shaft 11. The driving shaft 11 and the screw 13 in the drive box 9 cooperate with the driving motor 10 to push out the quick-release support assembly placed between the first sub-support U-shaped frame 306 and the second sub-support U-shaped frame 307, so that the quick-release support assembly restricted by the first sub-support U-shaped frame 306 and the second sub-support U-shaped frame 307 is pushed out. The second support base 5 is pushed by the hydraulic rod 8 and contacts the ground, and at this time the first support base 4 is still restricted by the first secondary support U-shaped frame 306 and the second secondary support U-shaped frame 307. Therefore, when the hydraulic rod 8 pushes the second support base 5 downward, the crawler track supported by the first secondary support U-shaped frame 306 and the second secondary support U-shaped frame 307 will be lifted, thereby completing the adjustment of the crawler track height. The chain can be lifted for maintenance during maintenance, and when the equipment is stationary or parked, the quick-release support assembly 309 can be extended through the drive box 9 and adjusted to contact the ground using the hydraulic rod 8, providing additional stable support for the equipment, thereby sharing the load of the walking mechanism.

[0045] A pushing groove 901 is provided at the top of the drive box 9, and a limiting connecting rod 14 is provided between the limiting hole 6 and the pushing groove 901, and a sliding structure is formed between the quick-release support assembly 309 and the drive box 9 through the limiting hole 6, the pushing groove 901 and the limiting connecting rod 14, and the limiting connecting rod 14 is fixedly installed in the limiting hole 6 set in the quick-release support assembly 309. When the quick-release support assembly 309 is pushed to move by the driving motor 10 and the screw 13, the limiting connecting rod 14 in the pushing groove 6 can support the quick-release support assembly 309, thereby maintaining stable support between the first support base 4 and the first sub-support U-shaped frame 306 and the second sub-support U-shaped frame 307 in the process of the quick-release support assembly 309 supporting the crawler.

[0046] Example 2: A crushing and screening machine includes the above-mentioned quick-release modular walking side beam, the vehicle frame 1 includes a mounting plate 101, a placement groove 102 and a side baffle 103, and the placement groove 102 is reserved at the top of the mounting plate 101, and the side of the placement groove 102 is installed with a side baffle 103 by bolts.

[0047] The vehicle chassis 2 includes a fastening frame 201 , a positioning rod 202 and a connecting frame 203 . The positioning rod 202 is provided below the fastening frame 201 , and the connecting frame 203 is installed on a side of the positioning rod 202 away from the fastening frame 201 .

[0048] The vehicle frame 1 and the vehicle chassis 2 form a fixed connection structure through the placement groove 102 and the connecting frame 203, and the vehicle chassis 2 and the traveling mechanism 3 form a detachable structure through the positioning rod 202 and the connecting frame 203.

[0049] The implementation principle of the embodiment of the present application is as follows: the main support U-shaped frame 305 is assembled with the first auxiliary support U-shaped frame 306 and the second auxiliary support U-shaped frame 307 by using multi-hole high-strength bolts and cooperating with the circular connecting ring and the drive wheel 302 and the guide wheel 304 during the connection process. When damaged, only the local module needs to be disassembled and replaced, and there is no need to replace the entire module. When separation is required, quick separation can be completed by dismantling the corresponding second auxiliary support U-shaped frame 307 without dismantling the entire structure, which shortens the replacement time. In addition, the quick-release support assembly 309 can also be used to assist in dismantling, reducing the total cost of replacing and maintaining parts, thereby achieving stable operation of the equipment.

[0050] The main support U-shaped frame 305, the first secondary support U-shaped frame 306 and the second secondary support U-shaped frame 307 are all made of high-strength aluminum alloy. The high strength and low weight of the aluminum alloy itself, and the bending rigidity are improved by the U-shaped cross-section design to reduce the overall weight of the mechanical equipment and meet the lightweight requirements of the mobile screening machine. In addition, at the multi-hole bolt connection provided at the fastening frame 201 of the vehicle chassis 2, alloy steel bolts are used and a double-bolt locking structure is adopted. The double-bolt locking structure is arranged according to the load distribution. The problem of bolt detachment is reduced by the double-bolt locking structure and the locking structure of the double bolts themselves, thereby achieving an overall lightweight design of the walking side beam while ensuring the connection strength.

[0051] The hydraulic telescopic function of the quick-release support assembly 309 adjusts the height difference between the first support base 4 and the second support base 5 through the hydraulic rod 8 to adapt to uneven ground or soft foundation conditions, and the six groups of positioning holes 7 cooperate with the limiting connecting rod 14 to accurately lock the support position to prevent the equipment from shifting.

[0052] The hydraulic motor reducer 3012 cooperates with the quick-release hydraulic motor 3013 to provide stable torque output, adapting to the original working conditions of the crawler 301. While reducing the original structural design and weight, it maintains the normal working state of the crawler 301, and both are connected to the second auxiliary support U-shaped frame 307. The quick-release hydraulic motor 3013 can be separated by disassembling the second auxiliary support U-shaped frame 307, so that the drive wheel 302 can be separated from the standardized interface of the quick-release hydraulic motor 3013 through the quick-release hydraulic motor 3013 structure, supporting plug-and-play, and shortening the time for emergency repairs.

[0053] The driving shaft 11 and the screw 13 in the drive box 9 cooperate with the drive motor 10 to fine-tune the height of the crawler 301 and the ground. The chain can be lifted for maintenance. When the equipment is stationary or parked, the quick-release support assembly 309 can be extended through the drive box 9 and adjusted using the hydraulic rod 8 to make it contact the ground, providing additional stable support for the equipment, thereby sharing the load of the walking mechanism.

[0054] The limiting connecting rod 14 is fixedly installed in the limiting hole 6 provided in the quick-release support assembly 309. When the quick-release support assembly 309 is pushed to move by the driving motor 10 and the screw 13, the limiting connecting rod 14 in the pushing groove 901 can support the quick-release support assembly 309, thereby ensuring the stable operation of the quick-release support assembly 309.
