An adaptive mechanism for sorting machine guide rails crossing civil engineering expansion joints

Abstract

The present invention belongs to the fields of logistics and postal equipment, and specifically discloses an adaptive mechanism for use when a sorting machine guide rail spans a civil engineering expansion joint. The mechanism includes a sorting machine guide rail disposed on a civil engineering area across the civil engineering expansion joint, and comprises two parallel tracks. A civil engineering area A and a civil engineering area B are formed on either side of the civil engineering expansion joint, without a rigid connection. The track located in civil engineering area A is fixed to the upper end surface of civil engineering area A via fixed legs, while the track located in civil engineering area B is mounted to the upper end surface of civil engineering area B via sliding legs. Compared to the prior art, the present invention employs a method in which the track legs on one side of the expansion joint are fixed, while the other side can slide in an extension and contraction direction. This solves the problem of the sorting machine track being compressed when the temperature rises and stretched when the temperature drops due to inconsistent expansion and contraction directions between the sorting machine track and the civil engineering, which can cause the sorting machine track to deform or break due to tension, leading to serious production accidents.

Description

Technical Field

[0001] The present invention relates to the fields of logistics and postal equipment, and in particular to an adaptive mechanism for a sorting machine guide rail when it crosses a civil engineering expansion joint. Background Art

[0002] With the development of the logistics industry, logistics sites are constantly expanding, and the number of expansion joints in the civil engineering within the sites is increasing. Equipment cannot be arranged and installed around these joints, which inevitably results in the sorter rails crossing over them. Due to the misalignment between the expansion and contraction directions of the sorter rails and the civil engineering during temperature fluctuations, the sorter rails compress when the temperature rises and stretch when the temperature drops. This can cause the sorter rails to deform or break, leading to serious production accidents.

[0003] After searching, no adaptive mechanism or method was found for the case where the guide rail of a sorting machine crosses the expansion joint of civil engineering. Therefore, it is urgent to develop an adaptive mechanism for the case where the guide rail of a sorting machine crosses the expansion joint of civil engineering. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an adaptive mechanism for a sorting machine guide rail when it crosses a civil engineering expansion joint.

[0005] To achieve the above object, the present invention is implemented according to the following technical solutions:

[0006] An adaptive mechanism for a sorting machine guide rail crossing a civil construction expansion joint, comprising a sorting machine guide rail arranged on a civil construction area across the civil construction expansion joint, the sorting machine guide rail comprising two parallel tracks; a civil construction area A and a civil construction area B, both sides of the civil construction expansion joint, formed without a rigid connection; the track located in civil construction area A is fixed to the upper end surface of civil construction area A via fixed legs, while the track located in civil construction area B is mounted on the upper end surface of civil construction area B via sliding legs that can slide along the expansion and contraction direction of the civil construction expansion joint.

[0007] Furthermore, the sliding support leg includes a fixed base plate, a pressure plate, a sliding base plate, a shock absorber and a sorting machine track connector. The top of the sorting machine track connector is fixed to the bottom of the track, the top of the shock absorber is fixedly installed at the bottom of the sorting machine track connector, the bottom of the shock absorber is fixed to the upper end surface of the sliding base plate, the pressure plate is fixed to the upper end surface of the fixed base plate on both sides of the sliding base plate, an L-shaped slide groove is opened on the inner side of the lower end surface of the pressure plate, and the two sides of the sliding base plate are slidably assembled in the L-shaped slide groove so that the sliding base plate slides along the expansion and contraction direction of the civil engineering expansion joint, and the fixed base plate is fixed to the upper end surface of the civil engineering area B.

[0008] Furthermore, the sum f of the friction force between the fixed base plate and the sliding base plate of the sliding support and the friction force between the sliding base plate and the pressure plate satisfies F1<f<F 许用, F 许用 It is the minimum value of the maximum allowable tension of the sorter guide rail, sorter track connector and shock absorber. F1 is the impact force generated when the sorter on the track is running.

[0009] Furthermore, the fixed base plates at both ends of the sliding base plate are respectively installed on the upper end surface of the civil engineering area B through two screws and nuts, and the top end of the screw is located above the upper end surface of the sliding base plate to form a limiting column.

[0010] Furthermore, the pressing plate is mounted on the upper end surface of the fixed base plate by means of bolts, and the bolts penetrate the pressing plate and are threadedly connected to threaded holes provided on the upper end surface of the fixed base plate.

[0011] Preferably, the track is arranged perpendicular to the civil engineering expansion joint.

[0012] Compared with the existing technology, the present invention adopts a method in which the rail support foot on one side of the expansion joint is fixed and the other side can slide in the extension and contraction direction. This solves the problem that when the temperature changes, the sorting machine guide rail is compressed when the temperature rises and stretched when the temperature drops, resulting in the sorting machine guide rail being squeezed and deformed or stretched and broken, causing serious production accidents.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1 As shown, an adaptive mechanism for a sorting machine guide rail crossing a civil engineering expansion joint comprises a sorting machine guide rail arranged on a civil engineering area across the civil engineering expansion joint, wherein the sorting machine guide rail comprises two mutually parallel tracks. Figure 1 In the embodiment, the track is arranged perpendicular to the civil expansion joint; the ground, floor or steel structure on both sides of the civil expansion joint is disconnected to form a civil area A and a civil area B without a rigid connection on both sides of the civil expansion joint; the track located in the civil area A is fixed to the upper end surface of the civil area A by fixed legs, and the track located in the civil area B is installed on the upper end surface of the civil area B by sliding legs that can slide along the expansion and contraction direction of the civil expansion joint.

[0021] The adaptive mechanism of the sorting machine guide rail in this embodiment, when it crosses the expansion joint of the civil engineering, uses a method in which the rail support foot is fixed on one side of the expansion joint and can slide in the extension and contraction direction on the other side. This solves the problem that when the temperature changes, the sorting machine guide rail is compressed when the temperature rises and stretched when the temperature drops due to the inconsistent expansion and contraction directions of the sorting machine guide rail and the civil engineering. As a result, the sorting machine guide rail is squeezed and deformed or stretched and fractured, causing serious production accidents.

[0022] See Figure 2 This embodiment exemplifies the structure of a sliding support leg, which includes a fixed base plate, a pressure plate, a sliding base plate, a shock absorber, and a sorting machine track connector. The top of the sorting machine track connector is welded to the bottom of the track, the top of the shock absorber is fixedly mounted to the bottom of the sorting machine track connector, and the bottom of the shock absorber is fixed to the upper surface of the sliding base plate. The shock absorber can provide shock absorption and buffering during the track sliding process; the pressure plate is fixed to the upper upper surface of the fixed base plate on both sides of the sliding base plate, and the inner side of the lower end surface of the pressure plate is provided with an L-shaped groove. The two sides of the sliding base plate are slidably assembled in the L-shaped groove to enable the sliding base plate to slide along the expansion and contraction direction of the civil construction expansion joint. The fixed base plate is fixed to the upper end surface of the civil construction area B. Of course, in some embodiments, the sliding support leg can also adopt other structures, as long as the track located in the civil construction area B can slide along the expansion and contraction direction of the civil construction expansion joint.

[0023] Please continue reading Figure 2 The fixed base plates at both ends of the sliding base plate are respectively installed on the upper end surface of the civil engineering area B through two screws and nuts. The top ends of the screws are located above the upper end surface of the sliding base plate to form limit columns. Since the sliding base plate is slidably assembled in the L-shaped slide groove on the lower end surface of the pressure plate, when the sorting machine guide rails and civil engineering expand or contract during heating or cooling, the limit columns can prevent the sliding base plate from sliding off the L-shaped slide groove on the lower end surface of the pressure plate.

[0024] During actual use, the pressure plate of this embodiment is installed on the upper end surface of the fixed base plate by bolts. The bolts pass through the pressure plate and are threadedly connected to the threaded holes opened on the upper end surface of the fixed base plate. By adjusting the tightness of the bolts, the pressure of the pressure plate on the sliding base plate can be adjusted, thereby achieving the purpose of adjusting the friction between the sliding base plate and the pressure plate.

[0025] For the structure of the above sliding feet, refer to Figure 5 The sum of the friction between the fixed base plate and the sliding base plate of the sliding support and the friction between the sliding base plate and the pressure plate satisfies F1<f<F 许用 , F 许用 is the minimum value of the maximum allowable tension of the sorting machine guide rail, sorting machine track connector, and shock absorber. F1 is the impact force generated when the sorting machine on the track is running. If the actual situation is f≥F 许用 , it is necessary to adjust the materials of the fixed base plate and the sliding base plate to reduce the friction coefficient, or add low-friction material between the two base plates to reduce the static friction between the fixed base plate and the sliding base plate to F1<f<F 许用 If the actual situation is f≤F1, it is necessary to tighten the fixing bolts of the pressure plate to increase the pressure of the pressure plate on the sliding base plate and increase the friction between the sliding base plate and the pressure plate until F1<f<F 许用 .

[0026] After adjusting the above sliding feet to meet the requirements that the sum of the friction between the fixed base plate and the sliding base plate of the sliding feet and the friction between the sliding base plate and the pressure plate satisfies F1<f<F 许用 Then, see 4. Figure 5 The specific working mode of the adaptive mechanism of the sorting machine in this embodiment when the guide rail crosses the civil engineering expansion joint is described in detail.

[0027] like Figure 3 As shown, when the track and civil engineering of the sorting machine are heated up, the civil engineering area A and the civil engineering area B move closer to the contraction direction of the civil engineering expansion joint, while the civil engineering area A and the track of the sorting machine on the civil engineering area are stretched away from the extension direction of the civil engineering expansion joint, that is, the expansion and contraction direction of the civil engineering area A and the civil engineering area B is exactly opposite to the expansion and contraction direction of the track of the sorting machine. At this time, due to the setting of the sliding legs, the track located in the civil engineering area B slides in the opposite direction of the expansion and contraction direction of the civil engineering area B through the sliding legs, thereby preventing the sorting machine guide rail from being squeezed, deformed, or stretched, and fractured.

[0028] like Figure 4As shown in the figure, when the sorting machine track and civil engineering are cooling down, the civil engineering area A and the civil engineering area B move away from each other in the direction of expansion of the civil engineering expansion joint, while the civil engineering area A and the sorting machine track on the civil engineering area are compressed and move toward the contraction direction of the civil engineering expansion joint. That is, the expansion and contraction direction of the civil engineering area A and the civil engineering area B is exactly opposite to the expansion and contraction direction of the sorting machine track. At this time, due to the setting of the sliding legs, the track located in the civil engineering area B slides in the opposite direction of the expansion and contraction direction of the civil engineering area B through the sliding legs, thereby preventing the sorting machine guide rail from being squeezed, deformed, or stretched, and fractured.

[0029] The technical solution of the present invention is not limited to the above-mentioned specific embodiments. Any technical variations made according to the technical solution of the present invention fall within the protection scope of the present invention.
