[0056] Exemplary embodiments of the present application are described herein with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating preferred embodiments of the application, are given by way of illustration only, since various changes and modifications within the scope of the application will become apparent to those skilled in the art from this detailed description.
[0057] It should be understood that, although some disadvantages of the door beam end cover and the door beam shown in Figure 1 , Figure 2 and Figure 3 are explained above, the structure of the door beam end cover and the door beam still has certain advantages compared with some prior art, especially has the advantage of being able to quickly install the cover plate. Figure 1 , Figure 2 and Figure 3 and the above description can still constitute part of the disclosure or embodiments of the present application.
[0058] Embodiments of the present application provide a door beam end cover, such as Figure 1As shown, the door beam end cover 100 can be arranged at both ends of the door beam, and connected with the cross beam 200 and the cover plate 300 respectively. Figure 4 As shown, the door beam end cover 100 can be provided with a damping mechanism 120 and an end plate 130, the damping mechanism 120 can be connected with the cover plate 300 to reduce the vibration of the cover plate 300, and further reduce the noise generated by the vibration of the cover plate 300. Figure 5
[0059] Specifically, the damping mechanism 120 can be arranged at the inner side (the side of the door beam end cover close to the cross beam and the cover plate) of the door beam end cover 100, and one damping mechanism 120 can be connected at each end of the cover plate 300. Figures 4 to 7 As shown, the damping mechanism 120 can include a pin shaft 121, a spring 122, a connecting part 123 and a check ring 124. The spring 122 can be sleeved on the pin shaft 121, and the extension and contraction deformation direction of the spring 122 can be consistent with the axial direction of the pin shaft 121. The connecting part 123 can be connected to the main body of the door beam end cover 100 (i.e. the end plate 130), and the connecting part 123 can be connected to the main body of the door beam end cover (i.e. the end plate 130) in the form of welding connection, bolt connection, etc. Alternatively, the connecting part 123 can be integrally formed with the main body of the door beam end cover 100 (i.e. the end plate 130).
[0060] The connecting part 123 can be a U-shaped plate, which can have two opposite protruding parts, i.e. a first protruding part 1231 and a second protruding part 1232, and the first protruding part 1231 and the second protruding part 1232 can form through holes respectively, and the two ends of the pin shaft 121 can pass through the through holes of the first protruding part 1231 and the second protruding part 1232 respectively. It can be understood that after the pin shaft 121 is arranged in the connecting part 123, the spring 122 sleeved on the pin shaft 121 can be limited between the first protruding part 1231 and the second protruding part 1232, and the spring 122 can be extended and contracted along the pin shaft 121 between the first protruding part 1231 and the second protruding part 1232 (here, it does not exclude that in some cases, the spring 122 can be stretched to make one end part of it protrude out of the connecting part). For example, in Figure 6 Figure 7 The first protruding part 1231 and the second protruding part 1232 of the connecting part 123 can be arranged opposite in the vertical direction.
[0061] As shown, the damping mechanism 120 can include a pin shaft 121, a spring 122, a connecting part 123 and a check ring 124. The spring 122 can be sleeved on the pin shaft 121, and the extension and contraction deformation direction of the spring 122 can be consistent with the axial direction of the pin shaft 121. The connecting part 123 can be connected to the main body of the door beam end cover 100 (i.e. the end plate 130), and the connecting part 123 can be connected to the main body of the door beam end cover (i.e. the end plate 130) in the form of welding connection, bolt connection, etc. Alternatively, the connecting part 123 can be integrally formed with the main body of the door beam end cover 100 (i.e. the end plate 130). Figure 6 Figure 7 As shown, the pin shaft 121 can form a shaft head 1211, a limiting end 1212 and a shaft body 1213. The shaft head 1211 can be formed at one end of the pin shaft 121, and the diameter of the shaft head 1211 can be larger than the inner diameter of the spring 122, so that the shaft head 1211 can push the spring 122 to compress it in the axial direction. The spring 122 can be sleeved to the shaft body 1213, that is, the diameter of the shaft body 1213 can be smaller than the inner diameter of the spring 122. The end of the shaft head 1211 can form the limiting end 1212, that is, the end of the side of the shaft head 1211 which is not connected to the shaft body 1213 can form the limiting end 1212. The diameter of the limiting end 1212 can be larger than the diameter of the shaft head 1211. The other end of the pin shaft 121, that is, the tail of the pin shaft 121 (the opposite end of the shaft head 1211) can be provided with a stop washer 124. The diameter of the limiting end 1212 and the diameter of the stop washer 124 can be respectively larger than the through hole of the protrusion adjacent to them, and the limiting end 1212 and the stop washer 124 are both arranged outside the protrusion adjacent to them (on the side of the two protrusions which are away from each other), so as to limit the movement of the pin shaft 121 in the axial direction, so that the pin shaft 121 cannot be disconnected from the connecting part 123 when moving in the axial direction. For example, as shown in Figure 6 and Figure 7 As shown, the limiting end 1212 can be arranged outside the first protrusion 1231, and the stop washer 124 can be arranged outside the second protrusion 1232, that is, the diameter of the limiting end 1212 can be larger than the diameter of the through hole of the first protrusion 1231, and the diameter of the stop washer 124 can be larger than the diameter of the through hole of the second protrusion 1232.
[0062] Preferably, one or both ends of the pin shaft 121 can also form a positioning groove 1214, which can extend in the axial direction of the pin shaft 121, and the positioning groove 1214 can form a shape fit with the protrusion to limit the circumferential rotation of the pin shaft 121. For example, as shown in Figure 6 and Figure 7 As shown, the shaft head 1211 can form the positioning groove 1214, the first protrusion 1231 can form a positioning key, the positioning groove 1214 can form a fit with the positioning key, and the fit between the positioning groove 1214 and the positioning key can limit the circumferential rotation of the pin shaft 121.
[0063] Preferably, the distance from the inner side of the shaft head 1211 (the side connected to the shaft body 1213) to the stop washer 124 can be substantially the same as the distance between the two protrusions of the connecting part.
[0064] Further, as shown in Figure 6 and Figure 7As shown, the spring 122 can be limited between the shaft head 1211 and the second protruding part 1232. When the damping mechanism 120 (spring 122) is not affected by external force, the spring 122 can push the shaft head 1211 in the axial direction, and then make the stop ring 124 abut against the second protruding part 1232. When the damping mechanism 120 is connected with the cover plate 300, the cover plate 300 can press the pin shaft 121 (limiting end 1212), so that the spring 122 is compressed to a certain extent. The shaft head 1211 and the limiting end 1212 of the pin shaft 121 can form an internal threaded hole, the cover plate 300 can form a screw through hole, and the screw 125 can be used to pass through the screw through hole of the cover plate 300 and be connected to the internal threaded hole, so that the damping mechanism 120 and the cover plate 300 are connected. After the spring 122 is compressed to a certain extent, the damping mechanism 120 can exert a force on the cover plate 300 to make the damping mechanism 120 closely contact with the cover plate 300, so as to weaken the vibration of the cover plate 300. The spring 122 can also buffer part of the vibration, so as to reduce the noise generated by the vibration of the cover plate 300.
[0065] Preferably, the screw 125 can be a cross head screw.
[0066] Preferably, as shown in Figure 6 As shown, after the cover plate 300 is connected with the damping mechanism 120, the compression amount of the spring 122 can be X (compared with the state that the damping mechanism is not connected with the cover plate). The design distance from the upper edge of the connecting part 123 (the outer end surface of the second protruding part) to the cover plate 300 can be H, and the design distance from the outer edge of the limiting end 1212 of the pin shaft 121 to the stop ring 124 (that is, the relative end surface of the stop ring 124 to the pin shaft) can be L. L can be greater than H, so that the damping mechanism 120 can press the spring after being connected with the cover plate 300. It can be understood that the difference between L and H is the compression amount X of the spring 122, that is, L-H=X.
[0067] As shown in Figure 4 and Figure 5 As shown, the damping mechanism 120 can be vertically arranged and connected to the inner bottom surface of the cover plate. It can be understood that the arrangement direction of the damping mechanism 120 can be changed according to actual needs, for example, the damping mechanism 120 can also be horizontally arranged and connected to the inner side surface of the cover plate.
[0068] The door machine beam end cover 100 can also be provided with a cover plate clamping part 110, the cover plate clamping part 110 can form a clamping block (wedge-shaped block) with an inclined surface, and the buckle part of the cover plate 300 can slide along the inclined surface. The cover plate clamping part 110 can include a cover plate pressing piece 111, when the buckle part of the cover plate 300 slides to the root of the inclined surface, the cover plate pressing piece 111 can abut against the buckle part of the cover plate 300, so that the buckle part is connected with the cover plate clamping part 110. The cover plate pressing piece 111 can also include a V-shaped groove, and the outer wall of the V-shaped groove can be used to abut against the buckle part of the cover plate 300, so that the buckle connection is more closely.
[0069] The embodiments of this application also provide a gantry crane beam, such as Figure 1 As shown, the gantry crane beam may include at least one of the aforementioned gantry crane beam end caps 100 (the vibration damping mechanism may be provided on only one side of the gantry crane beam end cap), as well as a crossbeam 200 and a cover plate 300. Preferably, both ends of the gantry crane beam are provided with the aforementioned gantry crane beam end caps 100 including the vibration damping mechanism. The crossbeam 200 may be connected to the cover plate 300, and both ends of the crossbeam 200 and the cover plate 300 may be connected to the gantry crane beam end caps 100. The vibration damping mechanism 120 may be connected to the cover plate 300 by screws 125.
[0070] Specifically, such as Figure 4 and Figure 5 As shown, the crossbeam 200 can be bolted to the boss formed by the gantry beam end cover 100, allowing the crossbeam to be securely connected to the gantry beam end cover 100. The crossbeam 200 may include a guide rail 220, which can be used to install rollers connecting to the gantry body. A cover plate slot 210 may be formed on the upper part of the crossbeam 200, and the cover plate 300 may have a first latching part 310 and a second latching part 320. The first latching part 310 can latch (hook) onto the cover plate slot 210 to connect the cover plate to the crossbeam 200. The second latching part 320 can latch onto the cover plate latching part 110 of the gantry beam end cover 100. When installing the cover plate 300, the first latching part 310 can be first latched into the cover plate slot 210, and then the cover plate 300 can be pushed so that the second latching part 320 slides along the inclined surface to the root of the cover plate engaging part 110, and the cover plate pressing plate 111 abuts against the second latching part 320. It can be understood that the above-mentioned connection method of the cover plate 300 is quick and convenient, and also facilitates the subsequent disassembly and assembly of the cover plate 300 for maintenance of the internal structure of the gantry beam. After connecting the first latching part 310 and the second latching part 320 of the cover plate 300 to the cover plate slot 210 and the cover plate engaging part 110 respectively, the cover plate 300 can be connected to the vibration damping mechanism 120 using screws 125.
[0071] Understandably, the cover plate 300 can shield and protect the internal structure of the gantry beam, while also decorating the gantry beam and enhancing the aesthetics of the sliding door.
[0072] Preferably, the lower part of the guide rail 220 may also be provided with a vibration damping strip 230, which is used to connect the guide rail 220 and reduce the vibration generated when the roller and other moving mechanisms move along the guide rail 220.
[0073] Preferably, the cover plate 300 may also include a sealing strip 330, which may be disposed at the contact point between the cover plate 300 and the door body or other structures to form a seal inside the door mechanism beam.
[0074] The embodiments of the present application also provide a sliding door, which can include the door beam and the door body described above. The door body can be connected to the door beam through a movement mechanism such as a roller, so that the door body can move along the door beam (the guide rail on the cross beam).
