Description

Technical Field

[0001] This invention relates to a transmission reversing mechanism in the field of machinery, and particularly to a pin-tooth transmission reversing mechanism for a track-type transverse and longitudinal moving vehicle. Background Technology

[0002] The existing rail-based transverse and longitudinal transfer method involves nested assembly of two frames, with transverse and longitudinal transfer achieved separately by the two sets of frames.

[0003] Advantages: Simple structure and easy operation.

[0004] Disadvantages: Low integration, takes up space; heavy.

[0005] The existing pin-tooth transmission mechanism uses a driving gear to drive a driven gear, which in turn drives a pin wheel to rotate, propelling the vehicle along the rack. This mechanism consists of two sets of drive mechanisms: one driven by gear meshing and the other by pin meshing.

[0006] Advantages: Low design difficulty and easy to implement.

[0007] Disadvantages: The mechanism is cumbersome with multiple layers of transmission; it requires a large installation space and is not suitable for compact spaces.

[0008] In view of the shortcomings of the existing technology, the inventors, through continuous research, design, and repeated trial production and improvement, have finally created this invention with practical value. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a track-type... The transverse and longitudinal movement vehicle pin gear transmission reversing mechanism solves the problems of low integration, large space occupation, and large weight, making it highly integrated, space-saving, and lightweight, thus more suitable for practical use.

[0010] The purpose of this invention is also to overcome the limitations of existing technologies in terms of complex mechanisms and hierarchical transmission. To address the shortcomings of high height and small installation space, a track-type transverse and longitudinal moving vehicle pin gear transmission reversing mechanism is provided. This mechanism solves the problems of cumbersome mechanism, multiple transmission levels, and large installation space, making it simpler, with fewer transmission levels and smaller installation space, thus making it more suitable for practical use.

[0011] The objective of this invention and the technical problem it solves are achieved by the following technical solution. According to this invention, a track-type transverse and longitudinal traversing vehicle pin-tooth transmission reversing mechanism includes: a guide mechanism, a slewing mechanism, and a steering wheel. The upper part of the slewing mechanism is connected to the guide mechanism, and the lower part of the slewing mechanism is bolted to the top plate of the steering wheel's traveling wheel bracket. The guide mechanism drives the steering wheel to perform lifting and lowering actions in accordance with the vehicle frame.

[0012] The steering wheel consists of a traveling wheel bracket, a traveling wheel, a hollow shaft, a pin wheel bracket, a first pin wheel, a second pin wheel, a large gear, and a pin wheel shaft. The first and second pin wheels are both welded together from two circular side plates and a set of pin teeth. The center holes of the first and second pin wheels are fitted with copper sleeves. The first and second pin wheels are driven by a large gear, and the transmitted driving force enables the synchronous rotation of the two sets of pin wheels. The first and second pin wheels enable the mechanism to achieve linear movement on a discontinuous rack: the two sets of pin wheels are driven by a large gear. When the first pin wheel passes through a rackless position, the second pin wheel can still transmit the walking power, and when the second pin wheel passes through a rackless position, the first pin wheel can still transmit the walking power.

[0013] Furthermore, the traveling wheel equipped with bearings is mounted on the traveling wheel bracket via a hollow shaft. The pin wheel bracket is welded together from a top plate and a vertical plate. The top plate of the pin wheel bracket is connected to the traveling wheel bracket by bolts. The vertical plate of the pin wheel bracket and one of the vertical plates of the traveling wheel provide support for the installation of the first pin wheel and the second pin wheel. The pin wheel shaft passes through the two supporting vertical plates and the center hole of the first pin wheel to install the first pin wheel on one side in the position where it meshes with the large gear. The installation and connection method of the second pin wheel on the other side is the same as that of the first pin wheel.

[0014] Furthermore, it also includes a power mechanism, which consists of a travel motor and a travel reducer to provide travel power. The power mechanism is mounted on a pin wheel bracket, in which part of the travel reducer extends into the hollow shaft, saving overall space. The travel reducer and the travel motor are assembled together by bolts and mounted on the pin wheel bracket with a flange. The large gear, which serves as the main drive wheel, is bolted to the travel motor.

[0015] Specifically, the power mechanism drives the large gear to rotate the first and second pins. When the power mechanism drives the large gear to rotate, the pin teeth of the first and second pins sequentially enter the tooth grooves of the large gear. The first and second pins are driven to rotate by the large gear, realizing the transmission of torque and speed. At the same time, the pin shafts on the first and second pins sequentially enter the tooth grooves on the rack of the large gear, realizing the linear motion of the first and second pins on the rack. Through two meshings between the large gear and the first and second pins, and between the first and second pins and the rack, the rotational motion of the power mechanism is converted into linear motion. The two meshings are the meshing of the tooth profiles of the large gear and the first and second pins, and the meshing of the tooth profiles of the first and second pins with the rack.

[0016] Furthermore, the guiding mechanism consists of a lifting cylinder and a guide column assembly; one end of the lifting cylinder is mounted on the vehicle frame, and the other end is mounted on the guide column assembly.

[0017] The guide column assembly consists of four guide columns welded together with a base. The four guide columns are respectively installed in four guide holes in the frame with copper sleeves. The base is equipped with a limiting mechanism to limit the reversing angle. The limiting mechanism adopts a threaded structure and the limiting angle is adjustable to achieve precise positioning of the reversing angle. Each guide column has an oil injection hole for installing an oil cup. Oil injection is used to lubricate the guide column and the copper sleeve. The base of the guide column assembly is equipped with a positioning column, which works with a proximity switch to detect the rising and falling height. The lifting cylinder is located in the middle of the base of the guide column assembly. The lifting drive guide column assembly moves up and down along the guide hole, driving the slewing mechanism and the steering wheel to achieve the lifting and lowering of the entire mechanism.

[0018] Furthermore, the slewing mechanism consists of a slewing bearing, a slewing reducer, and a slewing motor. The slewing reducer is mounted on the slewing bearing, and the slewing motor is mounted on the slewing reducer.

[0019] Furthermore, the slewing bearing includes an outer ring, an inner ring, a bearing, and a worm gear. There is a bearing between the inner and outer rings, which enables relative rotation. The outer ring and the worm gear transmit torque through a worm wheel and worm gear mechanism. The inner ring of the slewing bearing is provided with an oil injection hole, into which lubricating oil or grease is injected. The rotation of the slewing bearing drives the rudder wheel to rotate. When the slewing bearing rotates from 0° to 90°, it drives the rudder wheel's traveling wheel to rotate 90°, thus achieving longitudinal and transverse reversal.

[0020] Furthermore, the walking wheel bracket is composed of a top plate and two vertical plates welded together. Hollow shafts are installed at the bottom of the two vertical plates, and one of the vertical plates serves as the support for both the first and second pin wheels.

[0021] Furthermore, a spacer is provided between the bearing of the traveling wheel and the traveling wheel bracket to prevent the traveling wheel from moving axially.

[0022] This invention has significant advantages and beneficial effects compared with the prior art. It has at least the following advantages: 1. This invention has only one frame, and the lateral and longitudinal movement of the frame is achieved by reversing the steering wheel, resulting in a lightweight design.

[0023] 2. The present invention has a compact structure, with the track support steel wheel and drive pin wheel highly integrated, and a set of steering wheels used for both lateral and longitudinal movement.

[0024] 3. The driving force of this invention is transmitted through a pin-tooth transmission mechanism, which results in smooth transmission, simple structure, and good overall performance.

[0025] 4. The present invention uses one drive wheel to drive two driven wheels to move synchronously, which can continuously drive across teeth at the broken tooth location, thus solving the problem of tooth disengagement and re-engagement.

[0026] 5. The lifting and rotating structure used in this invention enables a 90° reversal, completing the longitudinal and transverse reversal.

[0027] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0031] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and preferred embodiments, describes a track-type lateral and longitudinal moving vehicle proposed according to the present invention. The pin-tooth transmission reversing mechanism, its specific implementation method, structure, method, features and effects are described in detail below.

[0032] See Figure 1 and Figure 2 As shown: A preferred embodiment of the present invention provides a track-type transverse and longitudinal traversing vehicle pin gear transmission reversing mechanism, comprising: a guide mechanism 1, a slewing mechanism 2, and a steering wheel 3, wherein the upper part of the slewing mechanism 2 is connected to the guide mechanism 1, and the lower part of the slewing mechanism 2 is bolted to the top plate of the traveling wheel bracket 9 of the steering wheel 3, and the guide mechanism 1 drives the steering wheel 3 to perform lifting and lowering actions in accordance with the vehicle frame.

[0033] The steering wheel 3 is composed of a traveling wheel bracket 9, a traveling wheel 10, a hollow shaft 11, a pin wheel bracket 12, a first pin wheel 13, a second pin wheel 14, a large gear 15, and a pin wheel shaft 18.

[0034] Both the first pin 13 and the second pin 14 are welded together from two circular side plates and a pin tooth assembly. The center holes of the first pin 13 and the second pin 14 are fitted with copper sleeves.

[0035] The first pin 13 and the second pin 14 are driven by a large gear 15, and the transmitted driving force enables the synchronous rotation of the two sets of pins. The first pin 13 and the second pin 14 enable the mechanism to move linearly on a discontinuous rack: the large gear 15 drives the two sets of pins, and when the first pin 13 passes through the rackless position, the second pin 14 can still transmit the moving power, and when the second pin 14 passes through the rackless position, the first pin 13 can still transmit the moving power.

[0036] The traveling wheel 10 equipped with bearings is mounted on the traveling wheel bracket 9 via a hollow shaft 11. A spacer is provided between the bearings mounted on the traveling wheel 10 and the traveling wheel bracket 9 to prevent the traveling wheel 10 from moving axially.

[0037] The pin wheel bracket 12 is welded from a top plate and a vertical plate. The top plate of the pin wheel bracket 12 is connected to the traveling wheel bracket 9 by bolts. The vertical plate of the pin wheel bracket 12 and one of the vertical plates of the traveling wheel 10 provide support for the installation of the first pin wheel 13 and the second pin wheel 14. The pin wheel shaft 18 passes through the two supporting vertical plates and the center hole of the first pin wheel 13 to install the first pin wheel 13 on one side in the position of meshing with the large gear 15. The installation and connection method of the second pin wheel 14 on the other side is the same as that of the first pin wheel 13.

[0038] Specifically, it also includes a power mechanism 19, which consists of a walking motor 17 and a walking reducer 16 to provide walking power. The power mechanism 19 is mounted on the pin wheel bracket 12, wherein a portion of the walking reducer 16 extends into the hollow shaft 11, saving overall space.

[0039] The travel reducer 16 and the travel motor 17 are assembled together by bolts and mounted on the pin wheel bracket 12 with a flange. The large gear 15, which serves as the main drive wheel, is mounted on the travel motor 17 by bolts.

[0040] Specifically, the power mechanism 19 drives the large gear 15 to rotate the first pin wheel 13 and the second pin wheel 14. When the power mechanism 19 drives the large gear 15 to rotate, the pin teeth of the first pin wheel 13 and the second pin wheel 14 sequentially enter the tooth grooves of the large gear 15. The first pin wheel 13 and the second pin wheel 14 are driven to rotate by the large gear 15, realizing the transmission of torque and speed. At the same time, the pin shafts on the first pin wheel 13 and the second pin wheel 14 sequentially enter the tooth grooves on the rack of the large gear 15, realizing the linear motion of the first pin wheel 13 and the second pin wheel 14 on the rack. Through two meshings between the large gear 15 and the first pin wheel 13 and the second pin wheel 14, and between the first pin wheel 13 and the second pin wheel 14 and the rack, the rotational motion of the power mechanism 19 is converted into linear motion. The two meshings are the meshing of the tooth profiles of the large gear 15 and the first pin wheel 13 and the second pin wheel 14, and the meshing of the tooth profiles of the first pin wheel 13 and the second pin wheel 14 with the rack.

[0041] Specifically, the guide mechanism 1 consists of a lifting cylinder 4 and a guide column assembly 5; one end of the lifting cylinder 4 is mounted on the frame, and the other end is mounted on the guide column assembly 5.

[0042] Specifically, the guide post assembly 5 is welded together from 4 guide posts and a base. The 4 guide posts are respectively installed in the 4 guide holes of the frame with copper sleeves. The base is provided with a limiting mechanism to limit the reversing angle. The limiting mechanism adopts a threaded structure and the limiting angle is adjustable to achieve precise positioning of the reversing angle. Each guide post has an oil injection hole for installing an oil cup. Oil injection is used to lubricate the guide post and the copper sleeve. The base of the guide post assembly 5 is equipped with a positioning post to detect the rising and falling height in conjunction with a proximity switch. The lifting cylinder 4 is located in the middle of the base of the guide column assembly 5. The lifting drive guide column assembly 5 moves the four guide columns up and down along the guide holes, driving the rotary mechanism 2 and the steering wheel 3 to achieve the lifting and lowering of the entire mechanism.

[0043] Specifically, the slewing mechanism 2 consists of a slewing bearing 6, a slewing reducer 7, and a slewing motor 8. The slewing reducer 7 is mounted on the slewing bearing 6, and the slewing motor 8 is mounted on the slewing reducer 7.

[0044] Specifically, the slewing bearing 6 includes an outer ring, an inner ring, a bearing, and a worm gear. There is a bearing between the inner and outer rings, which enables relative rotation. The outer ring and the worm gear transmit torque through a worm wheel and worm gear mechanism. The inner ring of the slewing bearing 6 is provided with an oil injection hole, into which lubricating oil or grease is injected.

[0045] The rotation of the slewing bearing 6 drives the rudder wheel 3 to rotate. The slewing bearing 6 rotates from 0° to 90°, which drives the traveling wheel 10 of the rudder wheel 3 to rotate 90°, thus realizing the reversal of direction.

[0046] Specifically, the walking wheel bracket 9 is composed of a top plate and two vertical plates welded together. Hollow shafts 11 are installed at the bottom of the two vertical plates, and one of the vertical plates serves as a support for the first pin wheel 13 and the second pin wheel 14.

[0047] The working principle of this invention is as follows: The present invention separates the load-bearing and driving functions, which are respectively implemented by the walking wheel 10, the first pin wheel 13, the second pin wheel 14, the large gear 15, the walking reducer 16, and the walking motor 17.

[0048] The 10 wheels serve a load-bearing function, supporting the weight of the frame and load.

[0049] The driving function is achieved by the power mechanism 19 (including a travel reducer 16 and a travel motor 17), a large gear 15, a first pinion 13, and a second pinion 14. The travel motor 17 provides driving force, which is reduced to the required speed by the travel reducer 16 while maintaining the driving torque. The large gear 15, the first pinion 13, and the second pinion 14 act as a power transmission mechanism to transmit the driving force to the rack, and the power transmission mechanism only transmits the driving force and does not bear the load.

[0050] When the power mechanism 19 drives the large gear 15 to rotate, the pin shafts of the first pin wheel 13 and the second pin wheel 14 sequentially enter the tooth grooves of the large gear 15. The first pin wheel 13 and the second pin wheel 14 are driven to rotate by the large gear 15, realizing the transmission of torque and speed. At the same time, the pin teeth on the first pin wheel 13 and the second pin wheel 14 sequentially enter the tooth grooves on the rack of the large gear 15, realizing the linear motion of the first pin wheel 13 and the second pin wheel 14 on the rack of the large gear 15. Through the two meshings between the large gear 15 and the first pin wheel 13 and the second pin wheel 14, as well as between the pin teeth and the rack, the rotational motion of the power mechanism 19 is converted into linear motion. The contact between the pin teeth and the tooth profile is a combination of rolling and sliding, the transmission process is smooth and can withstand large impact loads, making it suitable for large, low-speed, heavy-duty equipment.

[0051] The design of two sets of pins allows the mechanism to travel in a straight line on a discontinuous rack: since a large gear 15 drives two sets of pins (i.e., the first pin 13 and the second pin 14), when one set of pins passes through a rackless position, the other set of pins can still transmit the power of travel.

[0052] A lifting cylinder 4 is installed between the vehicle frame and the present invention, enabling the present invention to perform lifting actions.

[0053] The slewing bearing 4 is a worm gear mechanism. The slewing reducer 7 is mounted on the end of the worm. The slewing motor 8 rotates to drive the slewing reducer 7 to make the worm rotate around its axis. The worm gear mechanism converts the rotation of the worm around its axis (in the horizontal plane) into the rotational motion of the worm wheel (the rotation center is in the vertical plane). The slewing bearing 4 and the steering wheel 3 are connected by bolts, which can realize the reversal of the steering wheel from 0° to 90°.

[0054] 1. Rail changing procedure: The frame is supported by other mechanisms and bears the weight.

[0055] The lifting cylinder 4 retracts, and the guide column assembly 5 of the guide mechanism 1 drives the entire invention to be lifted, so that the steering wheel 3 is lifted away from the track and rack.

[0056] The slewing bearing 4 is driven by the slewing motor 8, which transmits torque through the slewing reducer 7, causing the steering wheel 3 to rotate 90° simultaneously.

[0057] The lifting cylinder 4 extends, and the guide column assembly 5 of the guide mechanism 1 drives the entire invention to descend, so that the traveling wheel 10, the first pin wheel 13, and the second pin wheel 14 fall onto the track and rack in another direction.

[0058] Other support mechanisms retract their support to the chassis, enabling rail replacement.

[0059] 2. Walking work procedure: The walking motor 17 rotates, driving the walking reducer 16 and the large gear 15 to rotate; The large gear 15 and the first pin wheel 13 and the second pin wheel 14 are driven by pin gear transmission, which drives the first pin wheel 13 and the second pin wheel 14 to rotate synchronously; The pins of the first pin wheel 13 and the second pin wheel 14 mesh with the rack (there is one pin tooth transmission) to realize the linear motion of the pin wheel on the rack.

[0060] Furthermore, the above examples include sequential exemplary steps, but these steps need not be performed in the order shown. Performing these steps in different orders is within the scope of this invention. Within the spirit and scope of the embodiments of this invention, these steps may be added, substituted, changed in order, and / or omitted as appropriate.

[0061] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the scope of the invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
