Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1, 2 and 3, the embodiment provides a lifting force station anti-reverse tool, which includes a base 1, a motor 2, a lifting force plate 3, a one-way bearing 4, a positioning pin 5, a positioning component 6, a damping spring 7 and a limiting rod 8. Wherein, base 1, motor 2 and one-way bearing 4 all can adopt current relevant part, and the frock of this embodiment can reequip, increase or replace spare part on current frock basis promptly.
In the present embodiment, the base 1 includes a first mounting block 11 and a second mounting block 12. An installation space for accommodating the rotation of the hoisting force plate 3 is formed between the first installation block 11 and the second installation block 12. The motor 2 is arranged on the first mounting block 11, and the one-way bearing 4 is arranged on the second mounting block 12. The first mounting block 11 and the second mounting block 12 may both be L-shaped, in some embodiments, the first mounting block 11 and the second mounting block 12 may be integrally connected, and in other embodiments, the first mounting block 11 and the second mounting block 12 may be separately provided. The base 1 can be connected with external equipment or integrally formed, so that a more stable supporting function can be provided for other parts, and the base can be conveniently combined with other equipment to form a new device, and the production and the use of the equipment are facilitated.
The motor 2 is mounted on the base 1, and may be fixed to the base 1 by a fixing member such as a bolt, or may be mounted on the base 1 by another mounting structure. The motor 2 may be a permanent magnet stepping motor, which is a pulse motor and is an actuator for converting an electric pulse into an angular displacement. In this embodiment, the driving mode of the motor 2 is four-phase eight-beat, and the power supply a-AB-B-BC-C-CD-D-DA sequentially energizes the coils to generate magnetic fields under the action of current, and the rotor is a 16-pole uniformly magnetized permanent magnet, so that the rotor rotates under the interaction of the magnetic fields, and is decelerated by gears at each stage to finally drive the output shaft to rotate.
The outer ring of the one-way bearing 4 is fixed on the base 1, and the inner ring is sleeved on the central shaft of the hoisting force disc 3 and limits the reverse rotation of the motor 2. The one-way bearing 4 is a bearing which can freely rotate in one direction and is locked in the other direction, and the one-way bearing can be locked when the motor 2 rotates reversely, so that the motor 2 cannot rotate reversely, and the anti-reverse function of the tool is realized. The one-way bearing 4 can be coaxially connected with the lifting force disc 3 through a shaft, so that when the motor 2 rotates reversely to drive the lifting force disc 3 to rotate, the locking effect can be generated, the lifting force disc 3 cannot rotate along the reverse direction of the motor 2, and the rotation of the motor 2 is further limited.
The hanging force plate 3 is rotatably arranged on the base 1 and is axially connected with an output shaft of the motor 2. The hanging force plate 3 can also be a weight hanging plate which can be driven by the motor 2 to wind an external rope so that equipment or components connected with the rope can ascend or descend, or the tool and equipment connected with the tool can ascend or descend through the rope, and the hanging force plate can be determined according to actual needs. In general, the suspension force plate 3 is in a normal working state when the motor 2 rotates forward, and stops rotating under the limiting action of the one-way bearing 4 when the motor 2 rotates backward, so that the whole suspension force plate is stopped. However, in practical use, especially when the tool is lifted and the motor 2 is powered off, the locking effect of the one-way bearing 4 can cause the tool to fall down, and at this time, the rotation of the hoisting force plate 3 can be ensured while the motor 2 is prevented from rotating reversely, so that the hoisting force plate 3 is improved by the implementation. The hoisting force plate 3 comprises an inner plate 31, an outer plate 32, a first limiting assembly, a second limiting assembly and a control unit.
The inner disc 31 is sleeved on the output shaft of the motor 2. Wherein, one side of the inner disc 31 is provided with a plurality of barbs 311 arranged around the center, and the inner ring of the one-way bearing 4 is connected with the inner disc 31 shaft. Here, for convenience of use and improved space utilization, the circular structure surrounded by all the first barbs 311 is located in the outer disk 32. One effect of inner disc 31 is the bridge that provides the connection for motor 2 and one-way bearing 4, can drive one-way bearing 4 between inner disc 31 when motor 2 reverses promptly, makes one-way bearing 4 carry on spacingly to motor 2. Another function of the inner disc 31 is to provide a driving action with the outer disc 32, as will be described later. The inner disc 31 is made of the same material as that of the conventional hoisting force disc, and the inner diameter of the inner disc can be the same as that of the conventional hoisting force disc, can be selected according to actual requirements, and can be determined according to the inner diameter of the one-way bearing 4.
A plurality of second barbs 321 surrounding the central axis of the inner disc 31 are arranged on the inner side wall of the outer disc 32, and the inclination direction of the second barbs 321 in the circumferential direction of the outer disc 32 is opposite to the inclination direction of the first barbs 311 in the circumferential direction of the inner disc 31. The outer disc 32 has a groove structure around which the outer cord is wound and opens at least one mounting space 322 facing the inner disc 31. In this embodiment, there is a gap between the inner disc 31 and the outer disc 32, and the outer diameter of the inner disc 31 is smaller than the inner diameter of the outer disc 32. The circle structure formed by all the second barbs 321 is located on one side of the inner disc 31, and all the second barbs 321 incline towards the same direction. Also, all of the barbs one 311 open on the other side of the inner disc 31. And, set up at least one locating hole one 322 on the outer dish 32, set up locating hole two 13 on the base 1, locating hole one 322 and locating hole two 13 can be located the same axial after the outer dish 32 rotates certain angle, and have the same radius. The groove structure serves for the winding of the suspension force wire, which is in fact an annular groove.
Referring to fig. 2, the first position-limiting component includes a first position-limiting pin 33, a first elastic component 34, and a telescopic component. One end of the first limit pin 33 is rotatably installed in the installation space 322, and the free end can be screwed into the space between the two adjacent first barbs 311. One end of the first elastic piece 34 is fixed on the outer disc 32, and the other end of the first elastic piece 34 is fixed on the first limit pin 33. The first elastic piece 34 is used for providing an elastic restoring force one for the first limit pin 33, so that the free end of the first limit pin 33 can be abutted against the notch one between the two adjacent barbs 311 due to stress. The telescopic assembly is installed in the installation space 322 and has a telescopic end coaxially connected with the first limit pin 33. The first elastic element 34 can be a limiting spring, one end of the first elastic element 34 is fixed on a platform arranged on the outer disc 32, and the other end of the first elastic element is fixed on the first limiting pin 33.
In this embodiment, the telescoping assembly includes a mounting post 37 and an electric telescoping member 38. One end of the mounting post 37 is movably mounted on the outer plate 32, and the other end is connected with the electric telescopic piece 38. The first limit pin 33 is sleeved on the mounting column 37, and the electric telescopic piece 38 enables the mounting column 37 to move in the axial direction of the inner disc 31 through expansion and contraction, so that the free end of the first limit pin 33 can cut into or separate from the first notch. Wherein, the electric telescopic element 38 can be selected as a micro electric push rod, which can realize the movement of the mounting column 37 only by changing a small displacement.
Referring to fig. 3, the second position-limiting assembly includes a second position-limiting pin 35 and a second elastic element 36, and the operation manner between the second position-limiting pin 35 and the second elastic element 36 is substantially the same as the operation manner between the first position-limiting pin 33 and the first elastic element 34, except that the rotation direction of the position-limiting is opposite. The second limit pin 35 is rotatably mounted on the inner disc 31, and the free end of the second limit pin 35 can be screwed into the space between the two adjacent barbs 321. In this embodiment, the second stopper pin 35 is installed on one side of the inner disc 31, and the free end can coincide with the second notch. The shape of the second limit pin 35 is similar to that of a pointer in a clock, in particular to that of a hour hand, but the rotation angle of the second limit pin is smaller. The second limit pin 35 can rotate on the side face of the inner disc 31, is made of rigid materials, has high hardness, and is not easy to deform, so that the inner disc 31 and the outer disc 32 can synchronously rotate after the second limit pin 35 is clamped into the notch.
One end of the second elastic element 36 is fixed on the inner disc 31, and the other end is fixed on the second limit pin 35. The second elastic element 36 is used for providing a second elastic restoring force to the second limit pin 35, so that the free end of the second limit pin 35 can be abutted against the second notch between the two adjacent second barbs 321 due to stress. The second elastic member 36 is installed on one side of the inner disc 31 and is a limit spring in this embodiment, and all the first barbs 311 are opened on the other side of the inner disc 31. One end of the limiting spring is fixed on the platform arranged on one side of the inner disc 31, and the other end of the limiting spring is fixed on the second limiting pin 35. When the motor 2 rotates forwards, the free end of the second limit pin 35 presses down the limit spring, so that the limit spring can prop against the second limit pin 35, and the free end cannot rotate further to be separated from the notch. In other embodiments, the second elastic member 36 may also be other elastic elements, and even in some special cases, the second elastic member 36 and the second limit pin 35 may be integrally formed, so as to integrate the two components for use.
The control unit is used for judging whether the motor 2 is in a power-off state, if so, the telescopic end is driven to enable the free end of the first limiting pin 33 to be separated from the first notch along the axial direction, otherwise, the telescopic end is driven to enable the free end of the first limiting pin 33 to be abutted against the first notch along the axial direction. When the control unit judges whether the motor 2 is in the power-off state, the control unit can receive power-on and power-off information detected by a power-on and power-off detection module arranged outside through the wireless communication module. When the motor 2 is powered off, the power-on and power-off detection module generates a power-off signal and transmits the signal to the control unit through the wireless communication module, and the control unit judges that the motor 2 is powered off according to the power-on signal and changes the state of the motor 2 from the power-on state to the power-off state.
The motor 2 has three states, which are a forward rotation state, a reverse rotation state and a power-off state, and the first two states are in a power-on state. When the motor 2 rotates forward, the free end of the second limit pin 35 slides over the long side of the second barb 321, and the free end of the first limit pin 33 is clamped in one of the notches under the limiting action of the short side of the first barb 311, so that the inner disc 31 and the outer disc 32 synchronously rotate to drive the groove structure to rotate. When the motor 2 rotates reversely, the inner disc 31 rotates to enable the one-way bearing 4 to lock the motor 2 reversely, the free end of the second limiting pin 35 is clamped in the second notch under the limiting effect of the short side edge of the second barb 321 to enable the outer disc 32 to be locked, although the first limiting pin 33 cannot play a limiting effect at the moment, the braking of the lifting force disc 3 can be guaranteed after the second limiting pin 35 is limited, and other operations can be conducted conveniently. When the motor 2 is in a power-off state, the free ends of the second limit pins 35 can slide on the long sides of all the second barbs 321, and meanwhile, as the first limit pins 33 are released by the control unit, the first limit pins 33 cannot enable the inner disc 31 and the outer disc 32 to be connected, so that the outer disc 32 can rotate relative to the inner disc 31. Like this, when motor 2 normally works, inner disc 31 and outer disc 32 constitute an organic whole, thereby make motor 2 drive whole lifting force dish 3 and rotate, thereby can realize the function of lifting by crane, and when motor 2 abnormal work or man-made going control, two 35 spacer pins then can slide two 321 of all barbs, make and produce relative rotation between inner disc 31 and the outer disc 32, outer disc 32 still can rotate after motor 2 outage like this, make equipment fall, thereby can also avoid the one-way unable circumstances that falls when preventing reversing, make things convenient for the frock to lift by crane work, improve frock application range and security.
The positioning pin 5 is used for being inserted into one of the positioning holes 322 through the positioning hole two 13, so that the outer disc 32 is fixed relative to the base 1. The positioning pin 5 can penetrate through the first positioning hole 322 and the second positioning hole 13, so that the lifting disc 3 and the base 1 can be relatively fixed, the tool can be conveniently positioned in real time, and particularly, an additional protection structure can be provided when equipment fails, and the tool is safer and more reliable to use. In this embodiment, the positioning pin 5 is a round pin, and the first positioning hole 322 and the second positioning hole 13 are round holes, which is more convenient in use.
The positioning member 6 is mounted on the base 1, and has a semi-annular shape and supports the one-way bearing 4. The positioning component 6 can play a role in supporting and positioning, and when the motor 2 rotates reversely, the one-way bearing 4 can be driven by a large amount of power, so that the one-way bearing 4 is easy to loosen. And the sunken position of locating part 6 and the outside laminating of one-way bearing 4 can support one-way bearing 4 like this, can also make the outer lane of one-way bearing 4 fix mutually with base 1 more firmly simultaneously.
The bottom end of the damping spring 7 is fixed on the base 1, and the top end is fixed on the bottom of the positioning component 6. The damping spring 7 can provide elastic acting force for the positioning part, so that the positioning part can support the one-way bearing more stably, and particularly when the large vibration occurs during the operation of the hoisting force plate, the damping spring can reduce the instability caused by the vibration. The elastic coefficient of the damping spring 7 can be selected according to actual requirements, and the selection requirement is that the associated vibration of the base 1 and the motor 2 can be reduced to the maximum extent.
One end of the limiting rod 8 is fixed on the positioning part 6, and the other end is inserted on the base 1. The damping spring 7 is sleeved outside the limiting rod 8. The limiting rod 8 can play a role in guiding, so that the positioning component can only move in the axial direction of the damping spring, and the damping effect is enhanced. The limiting rod 8 and the damping spring 7 can ensure that the positioning component 6 can only move towards the axial direction of the limiting rod 8, and can reduce larger vibration, so that the one-way bearing 4 is more stable.
