Description

Technical Field

[0001] This utility model mainly relates to the field of logistics transportation equipment technology, specifically to a multi-functional rail logistics trolley. Background Technology

[0002] Currently, in the field of logistics and warehousing, regional transportation of goods is relatively frequent. Therefore, rail-mounted trolleys with large load capacity and the ability to move back and forth are used to transfer goods. Rail-mounted logistics trolleys are widely used. On the market, logistics trolleys are usually installed by hanging or by short-distance vertical low-speed directional change. The low integration of the trolley tracks results in their excessive size and a large amount of on-site space occupied after wiring. Based on this, and in order to meet the diversified development of the market, a multi-functional rail-mounted logistics trolley has been proposed. Utility Model Content

Detailed Implementation

[0043] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] It should be noted that the structures not described in this utility model do not involve the design points and improvement directions of this utility model and all adopt existing technology. At the same time, the content in the above background technology is within the technical knowledge scope of the utility model owner. Since the technical content in this field is vast and too complex, the above content of this application does not necessarily constitute prior art.

[0046] Reference Figure 1-15 This embodiment provides a multi-functional rail logistics trolley, including a guide rail 1. The guide rail 1 is provided with a plurality of frame brackets 2 for wrapping the guide rail. The bottom surface of the frame brackets 2 is connected to the support frame 4 through a connecting frame 3. The support frame 4 is provided with a sling drive mechanism 5. The sling drive mechanism 5 is connected to the loading mechanism 6 on the bottom surface. The loading mechanism 6 is provided with a conveying mechanism 7 on the bottom surface.

[0047] The frame bracket 2 is equipped with a drive mechanism 8 for moving the loading mechanism 6 and the conveying mechanism 7.

[0048] The multi-functional rail logistics trolley provided by this utility model has a reasonable structure, occupies little space, is convenient for factory or workshop layout, and improves application space. The drive mechanism 8 drives the conveying mechanism 7 to move on the guide rail 1 to complete the efficient conveying of materials.

[0049] In a preferred embodiment, the drive mechanism 8 includes a servo motor 81 disposed on one side of the frame bracket 2. The output end of the servo motor 81 is provided with a drive wheel 82 that abuts against the guide rail 1. The other side of the frame bracket 2 is provided with a driven wheel 83 that is correspondingly disposed to the drive wheel 82. The driven wheel 83 abuts against the other side wall of the guide rail 1. Both ends of the remaining frame brackets 2 are provided with driven wheels 83 that abut against the guide rail 1. One end of the driven wheel 83 abuts against the guide rail 1, and the other end of the driven wheel 83 is disposed on the frame bracket 2 through a driven wheel shaft 84.

[0050] During the rotation of the servo motor 81, the drive wheel 82 is driven to rotate, and multiple driven wheels 83 cooperate with the drive wheel 82 to move the logistics cart.

[0051] In a preferred embodiment, the guide rail 1 is I-shaped, and the two ends of the frame bracket 2 are provided with assembly mechanisms that are adapted to slide with the ends of the guide rail. The assembly mechanism includes a plurality of guide wheels 9 disposed on the outside of the frame bracket 2 and corresponding to the guide rail 1. Each guide wheel 9 includes a limiting wheel seat 91 disposed on the outside of the frame bracket 2. A limiting wheel sliding seat 92 is slidably limited in the limiting wheel seat 91. A limiting wheel 93 adapted to slide with the guide rail 1 is rotatably disposed in the limiting wheel sliding seat 92. A plurality of studs 94 are provided at one end of the limiting wheel seat 91. The studs 94 pass through the limiting wheel seat 91 and are connected to a spring 95. The other end of the spring 95 is connected to the limiting wheel sliding seat 92.

[0052] Considering the sliding stability of the guide rail and the assembly mechanism, an assembly mechanism adapted to the bottom surface of the guide rail 1 is provided on the bottom surface of the frame bracket 2. The assembly mechanism consists of multiple guide wheels 9 adapted to be installed on both sides and the bottom of the guide rail 1 to improve the stability of the assembly.

[0053] In a preferred embodiment, the end face of the limiting wheel seat is provided with a guide plate 96, and the guide plate 96 is provided with a guide block 97 passing through the limiting wheel seat 91. The two ends of the limiting wheel sliding seat 92 are respectively provided with guide grooves 98 that are adapted to the guide block 97. The direction of the guide block 97 is consistent with the extension and retraction direction of the spring 95, ensuring that the limiting wheel 93 can be adaptively adjusted along the extension and retraction direction of the spring 95 (i.e., the direction perpendicular to the guide rail 1) when moving on the arc track, so as to meet the requirements of guide rails of different shapes. When the guide rail is an arc track, under the action of the spring tension and the action of the guide block, the limiting wheel will slide adaptively along the arc track. At the same time, the connection method of the stud 94 and the spring 95 is adopted, which improves the service life of the spring 95 compared to directly connecting the limiting wheel seat 91 and the limiting wheel sliding seat 92 with the spring 95.

[0054] The guide plate 96 is locked to the surface of the limiting wheel seat 91 by multiple locking elements 99.

[0055] In a preferred embodiment, the sling transmission mechanism 5 includes a dual-axis motor 51 disposed in the middle of the support frame 4. The output end of the dual-axis motor 51 is connected to a dual-belt pulley 52 via a rotating shaft. The dual-belt pulley 52 includes a pulley component 1 521 disposed in the middle and pulley components 2 522 and 3 523 disposed at both ends of pulley component 1 521. Pulley component 2 522 and pulley component 3 523 are respectively connected to pulley component 1 521 via fasteners 524.

[0056] There is a first gap between pulley component 1 521 and pulley component 2 522, and a second gap between pulley component 1 521 and pulley component 3 523. Belt 1 53 is installed at the end of the first gap, and belt 2 54 is installed at one end of the second gap which is diagonally opposite to the first gap. Belt 1 53 and belt 2 54 are wound in the same direction with staggered alignment through the working surface of pulley component 1 521.

[0057] Furthermore, belt 1 53 and belt 2 54 are connected to the sling shaft 61 located in the loading mechanism 6 after passing through guide pulley 1 55 and guide pulley 2 56 respectively. During the rotation of the dual-shaft motor 51, belt 1 53 and belt 2 53 are driven to be wound or unwound synchronously.

[0058] In this configuration, belt 1 53 and belt 2 54 are wound in the same direction with the pulley assembly 1 521 as the diagonal, thus achieving the superposition of belt 1 53 and belt 2 54. For details, refer to... Figure 14 53. Wrap the belt clockwise around point A in the diagram, and 54. Wrap the belt clockwise around point B in the diagram.

[0059] In this embodiment, belt 1 53 and belt 2 54 are respectively installed at both ends of the double belt pulley 52, and the ends of belt 1 53 and belt 2 54 are connected to the sling shaft 61 set in the loading mechanism 6, thereby connecting the loading mechanism 6 through two sets of belt 1 53 and belt 2 54.

[0060] The double-belt pulley 52 provided in this embodiment can have two sets of belts installed on its surface in a staggered manner. The ends of the two sets of belts are connected to the idler shaft 61 to realize the lifting of materials. With the addition of an adjustment mechanism, the extension and retraction of the belts can be adjusted according to the swing of the conveying mechanism to achieve smooth lifting and lowering of the entire mechanism during movement.

[0061] This embodiment also includes an adjustment mechanism 10, which includes a hinged mounting frame 101 disposed at one end of the support frame 2. A servo motor 102 is disposed on the hinged mounting frame 101. A lead screw 103 is disposed at the output end of the servo motor 102. A nut 104 is threadedly connected to the lead screw 103. A nut hinge seat 105 is disposed outside the nut 104.

[0062] The support frame 2 is provided with a rocker arm seat 106 at one end, a rocker arm 107 is hinged on the rocker arm seat 106, and the end of the rocker arm 107 is hinged to the nut hinge seat 105.

[0063] The swing arm 107 has a guide pulley 55 internally hinged at one end near the double-belt pulley 52;

[0064] Servo motor 102 drives lead screw 103 to rotate. Since nut 104 is limited within nut hinge seat 105, it drives nut hinge seat 105 and swing arm 107 to swing on swing arm seat 106, that is, the logistics trolley swings during the movement.

[0065] The other end of the support frame 2 is provided with a guide wheel seat 108 for mounting the second guide wheel 56.

[0066] Among them, the support frame 4 is assembled from multiple alloy profiles.

[0067] This embodiment also includes a cover 11 for wrapping the support frame 2, which serves to protect the internal structure of the support frame 2.

[0068] In a preferred embodiment, a lead screw buffer block 109 is provided at the end of the lead screw 103. The lead screw buffer block 109 is installed on the machine cover 11. This arrangement is to improve the stability of the lead screw 103 transmission.

[0069] This embodiment also includes a motor mount for fixing the second servo motor 102, which is disposed on the outside of the hinged mounting bracket 101. The motor mount is provided with a lead screw support bracket 110 for supporting the lead screw 103.

[0070] In this embodiment, a sliding contact line 12 is provided on one side of the guide rail 1, and a conductive sliding contact is provided on the sliding contact line 12 and slidably connected thereto. A conductive sliding contact seat 13 is provided at the end of the conductive sliding contact. The conductive sliding contact seat 13 is set on the corresponding frame bracket 2. The conductive sliding contact seat 13 is equivalent to providing a charging socket, and charging can be performed according to specific needs.

[0071] This embodiment also includes a level instrument installed on the conveying mechanism. The level instrument detects the swing angle of the conveying mechanism and then controls the adjustment mechanism to control the height of the two sets of belts. During the movement, the loading mechanism and the conveying mechanism connected by the two sets of belts rise and fall. That is, the logistics trolley will swing left and right. The level instrument detects the swing angle of the conveying mechanism and controls the belt to extend and retract to a certain extent according to the angle change, so as to overcome the inertia generated by the swing of the trolley and ensure that the entire mechanism rises and falls smoothly.

[0072] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
