Description

Technical Field

[0001] This utility model belongs to the technical field of speed-regulating cart pushers, specifically relating to a switched reluctance speed-regulating cart pusher. Background Technology

[0002] Switched reluctance speed-regulating trolley is a speed-regulating drive device based on switched reluctance motor technology, used to move vehicles or heavy objects. It is particularly suitable for industrial or logistics scenarios that require frequent starts and stops, a wide speed range, and high reliability.

[0003] Currently, in industrial production or related operational scenarios, when pushers apply pushing force to external equipment using push rods, according to the principles of physics, the push rods themselves will inevitably bear a large reverse force. This reverse force is directly transmitted to the mounting frame used to mount the push rods.

[0004] However, in actual design and manufacturing, due to limitations in material properties, space constraints, and cost, the overall thickness of the mounting frame often has an upper limit that is difficult to overcome. Under such circumstances, as the trolley pusher operates for extended periods and at high frequencies, the mounting frame, continuously subjected to significant reverse forces, is prone to wear. More seriously, when the reverse force exceeds the mounting frame's tolerance limit, the frame may even undergo significant bending deformation, severely affecting the normal operation of the trolley pusher, greatly shortening its service life, and increasing the cost of equipment maintenance and replacement. Utility Model Content

[0005] The purpose of this invention is to provide a switched reluctance speed-regulating cart pusher to solve the problem of short service life of existing cart pushers mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a switched reluctance speed-regulating trolley, including a connecting frame, an organic body mounted at the bottom, and a mounting frame mounted at the top. The mounting frame is welded from a base plate and a cover plate, wherein the cover plate is fixed to the top of the base plate, and the base plate is fixed to the connecting frame; a push rod, one end of which is rotatably mounted on the base plate of the mounting frame and located inside the cover plate, provides thrust to the required equipment during use; a force-sharing component is provided inside the mounting frame, the force-sharing component including:

[0007] Multiple contact elements are provided and distributed between the push rod and the inner wall of the mounting frame cover plate; the contact elements abut against the push rod that generates the reaction force, and disperse the reaction force of the push rod.

[0008] The clamping element has one end clamped against the bottom plate of the mounting frame and the other end clamped against the contact element. The clamping element is used to partially eliminate the reverse thrust of the push rod and reduce the force of the push rod acting on the cover plate of the mounting frame.

[0009] Preferably, the base plate of the mounting frame has multiple sliding grooves, and the length of the multiple sliding grooves gradually shortens from the inside of the mounting frame cover to the opening direction. Because the contact member inside the cover will always be in contact with the push rod during the rotation of the push rod, the sliding groove here is longer. The contact member at the opening of the cover will not contact the push rod in the initial state, so its length is shorter. The contact member includes a limiting plate that is horizontally slidably disposed inside the sliding groove. The side of the limiting plate facing the inner wall of the cover is also fixed with an inner frame. When the push rod rotates, it will push the limiting plate. One end of the abutment is inserted into the inner frame and abuts against the limiting plate. The rebound force of the abutment reduces the reverse thrust of the push rod.

[0010] Preferably, the clamping element is a spring, and one end of the spring is fixed to the inner wall of the sliding groove by spot welding.

[0011] Preferably, the connecting frame is fixed to the body and the base plate of the mounting frame by welding to ensure overall strength, and the cross-section of the connecting frame is smaller than the cross-sectional area of ​​the base plate of the mounting frame.

[0012] Preferably, the machine body is equipped with two traveling wheels on both sides. A track is also provided outside the two traveling wheels, and the two traveling wheels roll and fit against the inner wall of the track. A downward-protruding post is formed at the bottom of the machine body, which is fixedly connected to a chain. The chain is driven by a switched reluctance motor. The switched reluctance motor drives the chain to rotate, thereby moving the post and the entire trolley. During movement, a push rod pushes the designated equipment. The switched reluctance motor operates based on the principle of minimum magnetic reluctance. By controlling the energizing sequence and current magnitude of the stator windings, the rotor rotates at the position of minimum magnetic reluctance, achieving efficient energy conversion. Simultaneously, the motor speed and torque are adjusted in real time according to load requirements, achieving smooth start-up, acceleration, deceleration, and stopping. Through current closed-loop control, the thrust magnitude is precisely adjusted to adapt to different loads and working conditions. It supports forward and reverse rotation, electric and braking modes to meet the needs of complex motion trajectories. During braking, kinetic energy can be fed back to the power grid, improving system efficiency.

[0013] Preferably, the first and second traveling wheels are arranged vertically and do not contact each other.

[0014] Preferably, cleaning plates are bolted to both ends of the machine body, and cleaning brushes are bonded around the perimeter of the cleaning plates. The cleaning brushes abut against the inner walls of the track. When the cleaning plates move with the machine body, the cleaning brushes can remove any impurities that may be present on the inner walls of the track, thus avoiding affecting the normal movement of the first and second traveling wheels.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] To address the issue of damage to the mounting frame caused by the reverse force generated by the push rod of the trolley pusher, this utility model adds a force-sharing component. When the reverse force is generated, the force-sharing component can intervene and play a role, reasonably dispersing the reverse force that was originally concentrated at one point. By decomposing the force into multiple directions and parts, the strong compressive force that was originally acting directly on the mounting frame is significantly reduced. As a result, the pressure on the mounting frame is greatly reduced, and wear and bending deformation are effectively controlled during normal operation. This significantly extends the service life of the mounting frame, reduces equipment downtime and maintenance costs caused by damage to the mounting frame, and ensures the stable and efficient operation of the trolley pusher.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a switched reluctance speed-regulating trolley machine, including...

[0027] The connecting frame 100 has an organism 103 installed at the bottom and an installation frame 101 installed at the top. The installation frame 101 is welded from a base plate and a cover plate, wherein the cover plate is fixed to the top of the base plate, and the base plate is fixed to the connecting frame 100.

[0028] Push rod 102, one end of which is rotatably mounted on the base plate of mounting frame 101 and located inside the cover plate, provides thrust to the required equipment during use;

[0029] A force-sharing component is provided within the mounting frame 101. This force-sharing component includes:

[0030] Multiple contact elements are provided and distributed between the push rod 102 and the inner wall of the cover plate of the mounting frame 101; the contact elements abut against the push rod 102 that generates a reaction force, and disperse the reaction force of the push rod 102.

[0031] The clamping member has one end clamped against the bottom plate of the mounting frame 101 and the other end clamped against the contact member. The clamping member is used to partially eliminate the reverse thrust of the push rod 102 and reduce the force of the push rod 102 acting on the cover plate of the mounting frame 101.

[0032] In this embodiment, preferably, the bottom plate of the mounting frame 101 is provided with a plurality of sliding grooves 107, and the length of the plurality of sliding grooves 107 gradually shortens from the inside of the cover plate of the mounting frame 101 to the opening direction. Because the contact member inside the cover plate will always be in contact with the push rod 102 during the rotation of the push rod 102, the sliding groove 107 here is relatively long, while the contact member at the opening of the cover plate will not contact the push rod 102 in the initial state, so it is relatively short. The contact member includes a limiting plate 300 that is horizontally slidably disposed inside the sliding groove 107. The side of the limiting plate 300 facing the inner wall of the cover plate is also fixed with an inner frame 301. When the push rod 102 rotates, it will push the limiting plate 300, and one end of the abutment will be inserted into the inner frame 301 and abut against the limiting plate 300. The rebound force of the abutment reduces the reverse thrust of the push rod 102.

[0033] In this embodiment, preferably, the clamping element is a spring 302, one end of which is fixed to the inner wall of the sliding groove 107 by spot welding.

[0034] In this embodiment, preferably, the connecting frame 100 and the body 103, as well as the connecting frame 100 and the base plate of the mounting frame 101, are fixed by welding to ensure overall strength, and the cross-section of the connecting frame 100 is smaller than the cross-sectional area of ​​the base plate of the mounting frame 101.

[0035] In this embodiment, preferably, both sides of the machine body 103 are equipped with a first traveling wheel 105 and a second traveling wheel 106. A track 104 is also provided outside the first traveling wheel 105 and the second traveling wheel 106. The first traveling wheel 105 and the second traveling wheel 106 roll and fit against the inner wall of the track 104. A downwardly protruding post is also formed at the bottom of the machine body 103. The post is fixedly connected to a chain, and the chain is driven by a switched reluctance motor. The switched reluctance motor drives the chain to rotate, thereby moving the post and the entire pusher to move. During movement, the pusher... Rod 102 pushes the designated equipment, in which the switched reluctance motor operates based on the principle of minimum reluctance. By controlling the energizing sequence and current magnitude of the stator windings, the rotor rotates at the position of minimum reluctance, achieving efficient energy conversion. At the same time, the motor speed and torque are adjusted in real time according to load requirements to achieve smooth start, acceleration, deceleration and stopping. Through current closed-loop control, the thrust magnitude is precisely adjusted to adapt to different loads and operating conditions. It supports forward and reverse rotation, electric and braking modes to meet the needs of complex motion trajectories. During braking, kinetic energy can be fed back to the grid to improve system efficiency.

[0036] In this embodiment, preferably, the first walking wheel 105 and the second walking wheel 106 are vertically distributed and do not contact each other.

[0037] In this embodiment, preferably, cleaning plates 200 are bolted to both ends of the machine body 103. Cleaning brushes 201 are bonded around the perimeter of the cleaning plates 200. The cleaning brushes 201 abut against the inner walls of the track 104. When the cleaning plates 200 move with the machine body 103, the cleaning brushes 201 can remove any impurities that may be present on the inner walls of the track 104, thus avoiding affecting the normal movement of the first walking wheel 105 and the second walking wheel 106.
