Description

Technical Field

[0001] The present application relates to the technical field of tractors, and specifically discloses a linkage mechanism for a walking device with an auxiliary guiding function. Background Art

[0002] In the current production and processing of various products, the transportation of raw materials, intermediate products, finished products and other components within the factory is an indispensable part, which involves production loading, intermediate transportation of different processing techniques and product warehousing.

[0003] As for the transportation of product raw materials, intermediate products, finished products and other components, it is currently more common to use walking mechanisms as a means of transportation, such as cloth carts, wheeled shelves, trailers, etc. Among them, wheeled walking mechanisms are widely used due to their simple structure, low cost, and easy maintenance.

[0004] like Figure 1 As shown, in the process of transporting products in the current factory, one employee usually pulls and controls multiple wheeled walking mechanisms 1, and adjacent wheeled walking mechanisms 1 are connected mechanically by connecting plates 3, hooks 5 or chains with connecting pins 4 and other structures. This connection method can drive multiple wheeled walking mechanisms 1 to move through a vehicle body, etc., and the operation is convenient. However, when the wheeled walking mechanism 1 turns (for example, it is necessary to bypass a certain column 2 to transport the product), the turning radius of the rollers of the multiple wheeled walking mechanisms 1 will have a difference, that is, the inner wheel difference, among which the front and rear wheeled walking mechanisms 1 are more obvious, and when the same wheeled walking mechanism 1 turns, the outer roller and the inner roller will also have a radius difference, and the simple mechanical connection mechanism optimizes the inner wheel difference. The difference between the turning radius of the frontmost tire and the rearmost tire becomes greater as the more wheeled walking mechanisms 1 are connected, and the more difficult it is for workers to control the entire walking device, so that workers need to drive each wheeled walking mechanism 1 at a lower speed to prevent collisions. This limits the efficiency of the entire walking device and increases the risk of using the entire walking device. In addition, the wheeled walking mechanism 1 is affected by the inner wheel difference. When turning, the inner side of the mechanism is prone to scratching with the external environment. At the same time, the mechanism at the rear is affected by the centrifugal force and is prone to deviation after the turn. As a result, the outer side of the mechanism is prone to scratching with the external environment, and there is a risk of rollover. Therefore, the inventor has provided a linkage mechanism for a walking device with an auxiliary guiding function to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that traditional wheeled walking mechanisms are connected by hooks or chains with connecting pins and other structures, the inner wheel difference between different wheeled walking mechanisms is poorly optimized, and the efficiency of the wheeled walking mechanisms is limited.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a linkage mechanism for walking equipment with auxiliary guiding function, including:

[0007] A mounting assembly, the mounting assembly comprising a rotating wheel rotatably connected to the head of the wheeled walking mechanism and a fixed wheel fixedly connected to the tail of the wheeled walking mechanism;

[0008] A transmission member, wherein the transmission member is tensioned between each fixed wheel and the rotating wheel;

[0009] A rigid connecting member, the rigid connecting member being hinged between the middle parts of two adjacent wheeled walking mechanisms;

[0010] A bevel gear pair, wherein the driving bevel gears in the bevel gear pair are coaxially connected to each rotating wheel, and the driven gears in the bevel gear pair are coaxially connected to an adjusting gear, the adjusting gear is meshed with a rack, and the rack is slidably connected to the wheeled walking mechanism;

[0011] The adjusting shaft is coaxially connected with the roller of the wheeled walking mechanism, and the rack is provided with a brake sheet which can brake the adjusting shaft.

[0012] Furthermore, the brake pad is an elastic pad. When the inner and outer spacings of adjacent wheeled walking mechanisms are consistent, the elastic pad is disengaged from the adjustment shaft; when there is a difference in the inner and outer spacings of adjacent wheeled walking mechanisms, the elastic pad located on the side with the smaller spacing contacts the adjustment shaft and brakes the adjustment shaft.

[0013] Furthermore, there are two rotating wheels, which are respectively arranged on the inner and outer sides of the wheeled walking mechanism. The driving bevel gears in the bevel gear pair are respectively located below the rotating wheels and coaxially connected to the rotating wheels. The driven bevel gears in the bevel gear pair are symmetrically meshed with the driving bevel gears along the center line of the wheeled walking mechanism.

[0014] Furthermore, the positions of the transmission member and one of the fixed wheels are fixed to each other.

[0015] Furthermore, the rotating wheel is a synchronous pulley, and the matching portion between the transmission member and the rotating wheel is a synchronous belt.

[0016] Furthermore, it also includes elastic connecting parts, which are arranged between adjacent wheeled walking mechanisms and are evenly distributed on the inner and outer sides of each wheeled walking mechanism; when the spacing between adjacent wheeled walking mechanisms changes, the elastic connecting parts located on the inner and outer sides of each wheeled walking mechanism undergo elastic deformation in the same direction.

[0017] Furthermore, the elastic connector includes two integral springs symmetrically arranged at the head and tail of the wheeled walking mechanism, the two sides of the integral spring are respectively connected to the inner side and the outer side of the wheeled walking mechanism, and also includes a locking member that can lock the two integral springs to each other.

[0018] Furthermore, at least two locking holes are provided at one end of the integrated spring sheet away from the wheeled walking mechanism, and the locking member is a locking stud that can cooperate with the locking holes.

[0019] Furthermore, at least two locking holes are provided at one end of the integrated spring sheet away from the wheeled walking mechanism, the cross-section of the locking hole is cam-shaped, the locking member is a cone vertically slidably connected to the locking hole, and the end of the cone is larger than the maximum diameter of the locking hole.

[0020] Furthermore, the integrated spring leaves are all hinged to the wheeled walking mechanism.

[0021] The principles and effects of this basic solution are:

[0022] 1. Compared with the prior art, the utility model provides a rotating wheel and a fixed wheel. When two adjacent wheeled traveling mechanisms turn, the inner spacing of the adjacent wheeled traveling mechanisms becomes smaller and the outer spacing becomes larger, causing the transmission member to pull the rotating wheel to rotate, and then drive the conditional gear to rotate through the rotation of the bevel gear pair, thereby driving the rack to slide, so that the brake pad approaches the adjusting shaft to brake the roller on the inner side of the wheeled traveling mechanism, and due to the symmetrical arrangement of the bevel gear pair, the rotation direction of the two adjusting gears, that is, the outer adjusting gear drives the corresponding rack to move, so that the corresponding brake pad is away from the roller, and does not affect the normal movement of the roller, so that the outer roller of the rear wheeled traveling mechanism rotates normally and the inner roller is braked, forming a speed difference, reducing the influence of the inner wheel difference on the two wheeled traveling mechanisms, thereby pulling the rear wheeled traveling mechanism to rotate, that is, playing an auxiliary guiding role.

[0023] 2. Compared with the prior art, the utility model adopts an integrated spring to connect two wheeled walking mechanisms. When two adjacent wheeled walking mechanisms turn, the inner spacing of the two wheeled mechanisms becomes smaller, and the integrated spring is compressed. Since the overall deformation of the integrated spring is uniform, the outer portion of the integrated spring is also compressed, so that the outer spacing of the two wheeled mechanisms also has a tendency to decrease, which has a suppressive effect on the increase in the outer spacing of the two adjacent wheeled walking mechanisms when turning, reduces the outer clearance increased due to turning, plays a role in controlling the clearance on both sides, thereby reducing the influence caused by the inner wheel difference, and plays a role in turning guidance.

[0024] 3. Compared with the prior art, the utility model also adopts a cone and an integrated spring leaf, so that two integrated spring leaves in contact with each other can move relative to each other to a certain extent, increasing the restricted space. At the same time, after the movement, the adjacent integrated spring leaves can restore balance through the action of the cone, which plays a role in controlling the gap on both sides, thereby reducing the influence caused by the inner wheel difference and playing a role in turning guidance.

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] The figure marks in the drawings of the specification include: wheeled walking mechanism 1, column 2, connecting plate 3, connecting pin 4, hook 5, integrated spring leaf 6, locking stud 7, hinge seat 8, cone 9, lock hole 10, fixed wheel 11, rotating wheel 12, transmission part 13, rigid connecting part 14, active bevel gear 15, driven bevel gear 16, adjusting gear 17, rack 18.

[0035] A linkage mechanism for a walking device with an auxiliary guiding function, the embodiment of the invention is as follows Figure 2 As shown, it includes elastic connectors respectively arranged between two wheeled traveling mechanisms 1, and the elastic connector adopts two integrated spring leaves 6 symmetrically arranged at the head and tail of the wheeled traveling mechanism 1. The two sides of the integrated spring leaf 6 are respectively hingedly connected to the inner side and the outer side of the wheeled traveling mechanism 1, and correspondingly, an articulated seat 8 matched with the end of the integrated spring leaf 6 is arranged at the end of the wheeled traveling mechanism 1. The hinged arrangement allows the integrated spring leaf 6 to be stored in the side wall of the wheeled traveling mechanism 1 when the wheeled traveling mechanism 1 is not in use; at least two locking holes 10 are provided at one end of the integrated spring leaf 6 away from the wheeled traveling mechanism 1, and adjacent locking holes 10 are matched with each other through a locking stud 7 as a locking member, so that the positions of the two integrated spring leaves 6 are relatively stable.

[0036] Compared with the existing traction mechanism composed of a connecting plate 3, a connecting pin 4 and a hook 5, the use of an integrated spring leaf 6 can utilize its elastic deformation in the same direction. When two adjacent wheeled walking mechanisms 1 pass through a certain column 2 to turn, when the inner spacing between the two wheeled mechanisms becomes smaller, the integrated spring leaf 6 is compressed by force. Since the overall deformation of the integrated spring leaf 6 is uniform, the part of the integrated spring leaf 6 located on the outside is also compressed, so that the outer spacing between the two wheeled mechanisms also has a tendency to decrease, which has a suppressive effect on the tendency of the outer spacing between the two adjacent wheeled walking mechanisms 1 to increase when turning, reduces the outer clearance increased due to turning, plays a role in controlling the clearance on both sides, thereby reducing the influence caused by the inner wheel difference, and plays a role in turning guidance.

[0037] like Figure 3 and Figure 4As shown, the difference between the second embodiment and the first embodiment is that the cross section of the lock hole 10 in the second embodiment is a cam shape with one end larger and the other end smaller, and adjacent lock holes 10 are matched with each other through a cone 9 as a locking member, and the cone 9 is vertically slidably connected to the lock hole 10, and the end of the cone 9 is larger than the maximum diameter of the lock hole 10, so that the two integral spring leaves 6 in contact with each other can move relative to each other to a certain extent, increasing the restricted space, and at the same time, after the movement, the adjacent integral spring leaves 6 can restore the balance through the action of the cone 9, which plays a role in controlling the gap on both sides, thereby reducing the influence caused by the inner wheel difference and playing a role in turning guidance.

[0038] A linkage mechanism for a walking device with an auxiliary guiding function, embodiment 3 is as follows Figure 5 As shown, it includes: a mounting assembly, a transmission member 13, a rigid connection member 14, a bevel gear pair, an adjustment shaft and other structures, which are specifically as follows:

[0039] The mounting assembly includes a rotating wheel 12 rotatably connected to the head of the wheeled traveling mechanism 1 and a fixed wheel 11 fixedly connected to the tail of the wheeled traveling mechanism 1. There are two fixed wheels 11 and two rotating wheels 12, which are respectively arranged on the inner side and the outer side of the wheeled traveling mechanism 1.

[0040] The transmission member 13 is tensioned between each fixed wheel 11 and the rotating wheel 12; the transmission member 13 can directly use a belt, and the rotating wheel 12 can use a pulley. The position of the transmission member 13 and one of the fixed wheels 11 is fixed to each other by rivet locking. Of course, in order to avoid the belt slipping, the rotating wheel 12 can use a synchronous pulley, and a synchronous belt is used at the matching position between the transmission member 13 and the rotating wheel 12, and belts are used at other positions.

[0041] The rigid connecting member 14 is hinged between the middle parts of two adjacent wheeled walking mechanisms 1 to maintain the stability of the overall length of the fixed wheel 11 and the rotating wheel 12 and prevent the transmission member 13 from being separated from the fixed wheel 11 and the rotating wheel 12.

[0042] The driving bevel gears 15 in the bevel gear pair are respectively located below the rotating wheel 12 and are coaxially connected with the rotating wheel 12. The driven bevel gears 16 in the bevel gear pair are symmetrically meshed with the driving bevel gears 15 along the center line of the wheeled traveling mechanism 1. The driven gears in the bevel gear pair are coaxially connected with an adjusting gear 17. The adjusting gear 17 is meshed with a rack 18. The rack 18 is slidably connected to the wheeled traveling mechanism 1. Correspondingly, a slide rail is configured at the bottom of the wheeled traveling mechanism 1 to limit and guide the sliding of the rack 18.

[0043] The adjusting shaft is coaxially connected to the roller of the wheeled walking mechanism 1 , and a brake pad for braking the adjusting shaft is provided on the rack 18 , and the brake pad can be an elastic rubber pad.

[0044] like Figure 6 As shown, when the two wheeled traveling mechanisms 1 travel in a straight line, the distance between the two wheeled traveling mechanisms 1 is relatively stable, and the distance between the transmission member 13 and the rotating wheel 12 is relatively stable. At this time, the traction effect is mainly achieved through the rigid connecting member 14; Figure 7 As shown, when two wheeled traveling mechanisms 1 turn, the inner spacing between adjacent wheeled traveling mechanisms 1 becomes smaller and the outer spacing becomes larger, causing the transmission member 13 to pull the rotating wheel 12 to rotate, for example Figure 7 When the transmission member 13 and the outer fixed wheel 11 are fixed to each other, since the fixed wheel 11 is away from the corresponding rotating wheel 12, the transmission member 13 drives the two rotating wheels 12 to rotate counterclockwise, that is, drives the active bevel gear 15 in the two bevel gear pairs to rotate counterclockwise, drives the inner driven bevel gear 16 to rotate clockwise and the outer bevel gear to rotate counterclockwise, that is, drives the inner adjusting gear 17 to rotate clockwise and the outer adjusting gear 17 to rotate counterclockwise, that is, drives the inner rack 18 to slide outward and the outer rack 18 to slide inward, so that the brake pad on the inner rack 18 approaches the adjusting shaft and contacts the adjusting shaft, and the outer brake pad is away from the adjusting shaft, so that the outer roller of the rear wheeled walking mechanism 1 rotates normally and the inner roller is braked, forming a speed difference, reducing the influence of the inner wheel difference on the two wheeled walking mechanisms 1, thereby pulling the rear wheeled walking mechanism 1 to rotate, that is, playing an auxiliary guiding role.

[0045] A linkage mechanism for a walking device with an auxiliary guiding function, embodiment 4 combines embodiment 3 with embodiment 1 or embodiment 2 to achieve multiple auxiliary guiding effects, further optimize the inner wheel difference of the wheeled walking mechanism 1 when turning, thereby solving the problem that the traditional wheeled walking mechanisms 1 are connected by hooks 5 or chains with connecting pins 4 and other structures, the inner wheel difference between different wheeled walking mechanisms 1 is poorly optimized, and the efficiency of the wheeled walking mechanism 1 is limited.

[0046] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
