[0028] The specific implementation manners of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present application, and are not used to limit the present application.
[0029] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.
[0030] As Figure 1 shown, a first exemplary embodiment of the present application provides a crane support, which mainly includes a support main body 1, a plurality of pin shaft drive devices 2 and a plurality of device installation structures 3. Among them, the support main body 1 can be the upper support or the lower support of the crane slewing body. In this embodiment, the upper support is taken as an example, which includes a plurality of main body ear plates 101 provided on the peripheral wall. Each main body ear plate 101 is formed with an ear plate pin hole through which a pin shaft 4 can be passed. For example, the ear plate pin hole and the boom through hole can be passed through by the pin shaft 4, so that the boom can be hinged to the support main body 1. The plurality of pin shaft drive devices 2 are respectively arranged corresponding to the plurality of ear plate pin holes, and are used to drive the corresponding pin shaft 4 to be inserted and pulled out of the corresponding ear plate pin hole. The plurality of device installation structures 3 are respectively used to relatively fix the plurality of pin shaft drive devices 2 to the corresponding main body ear plates 101.
[0031] It can be seen that the crane support of this exemplary embodiment can relatively fix the pin shaft drive device 2 to the corresponding main body ear plate 101 by using the device installation structure 3, so that the pin shaft drive device 2 can drive the corresponding pin shaft 4 to be inserted and pulled out of the ear plate pin hole in the corresponding main body ear plate 101, thereby realizing the quick disassembly and assembly of the pin shaft 4. Moreover, the cooperation form between the pin shaft drive device 2 and the device installation structure 3 is relatively simple, making the disassembly and assembly of the pin shaft more efficient and labor-saving, while reducing the probability of damage to the pin shaft 4 during the insertion and pulling process, thereby effectively extending the service life of the pin shaft 4.
[0032] In an alternative or preferred embodiment, as Figure 1As shown, the pin shaft driving device 2 is formed as a telescopic driving device 201 that is coaxially arranged with the corresponding ear plate pin hole and can drive the corresponding pin shaft 4 to be inserted and pulled out by forming a telescopic movement. Specifically, the telescopic driving device 201 includes a cylinder barrel portion as a fixed end and a telescopic rod that is telescopically movably inserted into the cylinder barrel portion. The pin shaft 4 can be connected to the telescopic rod. By driving the telescopic rod to move through the cylinder barrel portion, the telescopic rod can drive the pin shaft 4 to move along the axial direction of the ear plate pin hole, so as to insert or pull out the pin shaft 4 from the ear plate pin hole. In this embodiment, the telescopic driving device 201 is a hydraulic cylinder and is used in cooperation with a pumping station. In other embodiments, the telescopic driving device 201 can also be a pneumatic cylinder and an electric telescopic cylinder, etc., and the present application does not limit this.
[0033] In an alternative or preferred embodiment, the device mounting structure 3 includes a carrier box body 301 that is connected to the main body ear plate 101 and loads the telescopic driving device 201. Specifically, the carrier box body 301 is arranged in alignment with the ear plate pin hole of the main body ear plate 101. By placing the telescopic driving device 201 in the carrier box body 301, the telescopic driving device 201 can be coaxially aligned with the main body ear plate 101. At the same time, by placing the pin shaft 4 in the carrier box body 301, the telescopic driving device 201 can drive the pin shaft 4 to be inserted into the corresponding ear plate pin hole, or when it is necessary to pull out the pin shaft 4, the telescopic driving device 201 can pull out the pin shaft 4. At this time, the pin shaft 4 can fall into the carrier box body 301, avoiding its dropping and loss as well as causing high-altitude accidents.
[0034] As Figure 1 shown, the carrier box body 301 includes an assembled carrier box body 3011 and a fixed carrier box body 3012. Among them, the assembled carrier box body 3011 is detachably connected to the corresponding main body ear plate 101. Specifically, referring to Figure 1 , a secondary ear plate is provided on the side wall of the main body ear plate 101, and an ear plate connection hole is provided on the secondary ear plate. A box body connection hole is provided on the assembled carrier box body 3011. By aligning the box body connection hole and the ear plate connection hole and passing through the box body connection hole and the ear plate connection hole with a connecting piece such as a secondary pin shaft, the assembled carrier box body 3011 can be detachably installed on the main body ear plate 101. The fixed carrier box body 3012 can be fixedly connected to the corresponding main body ear plate 101 by means of welding, nailing, etc., and the present application does not limit the specific connection method.
[0035] In an alternative or preferred embodiment, as Figure 1As shown, a box body slot 3013 is provided on the object holding box body 301, and a device clamping shaft 2011 is provided on the fixed end of the telescopic driving device 201. When the telescopic driving device 201 is loaded on the object holding box body 301, the device clamping shaft 2011 is clamped in the box body slot 3013, that is, the device clamping shaft 2011 and the box body slot 3013 form a clearance fit, thereby realizing the rapid installation and disassembly of the telescopic driving device 201.
[0036] Further, in the case where two main body ear plates 101 are connected to both ends of the supporting box body 301 and are spaced apart from each other, the supporting box body 301 can be loaded with two telescopic drive devices 201 corresponding to the two main body ear plates 101, so that the two telescopic drive devices 201 can respectively drive the two pins 4 to be respectively inserted and pulled out of the two main body ear plates 101, thereby saving the number of supporting box bodies 301 and making the supporting box body 301 more stable. Accordingly, the supporting box body 301 can be provided with at least two box body slots 3013, and the two box body slots 3013 are arranged at intervals from each other, so that the two telescopic drive devices 201 can be respectively engaged with the two box body slots 3013.
[0037] In some embodiments, the storage box body 301 may be provided with a plurality of box body slots 3013, and the plurality of box body slots 3013 are arranged in sequence and at intervals, and the telescopic drive device 201 can be selectively engaged in the corresponding box body slots 3013, so that the distance between the telescopic drive device 201 and the ear plate pin hole can be adjusted, and then the distance of the telescopic drive device 201 pulling the pin shaft 4 can be changed.
[0038] In an optional or preferred embodiment, Figure 1 As shown, the crane support includes a pin 4, which includes a pin body and a pin quick-connect structure. The pin drive device 2 is formed with a device quick-connect structure for aligning and connecting with the pin quick-connect structure, thereby enabling quick connection and disassembly of the pin 4 and the pin drive device 2.
[0039] Specifically, the pin quick-connecting structure includes a quick-connecting shaft body extending from one end of the pin body and a quick-connecting cap body connected to the outer end of the quick-connecting shaft body. The device quick-connecting structure is formed into a quick-connecting card slot for clamping with the quick-connecting cap body. Among them, the quick-connecting card slot is formed with a card slot avoidance opening for avoiding the quick-connecting shaft body. Thus, when installing the pin 4, first snap the quick-connecting cap body into the quick-connecting card slot so that the quick-connecting cap body is limited in the quick-connecting card slot, and then place the quick-connecting shaft body in the object-carrying box body 301 through the card slot avoidance opening, thereby completing the quick placement of the pin 4. The entire installation process is simple and fast, which is beneficial to improving the operation efficiency. Of course, in the case where the pin 4 has been inserted into the ear plate pin hole, based on the above structure, the quick-connecting card slot can also be sleeved on the quick-connecting cap body first, and then the pin driving device 2 as a whole is placed in the object-carrying box body 301, thereby completing the quick placement of the pin driving device 2 to facilitate the pin driving device 2 to pull out the pin 4.
[0040] The second exemplary embodiment of the present application provides a crane, and the crane includes the above-mentioned crane support. Obviously, the crane in this exemplary embodiment has the technical effects brought by the above-mentioned crane support, so it will not be elaborated here.
[0041] In this embodiment, the crane can be a tower crane, or a mobile crane, a mast crane, etc., and the present application does not make a limit thereto.
[0042] In a specific embodiment, the pin insertion process of the pin 4 in the crane support of the present application is as follows:
[0043] Step 1: Clamp the device card shaft 2011 of the telescopic driving device 201 in the box body card slot 3013, and place and fix the telescopic driving device 201 as a whole in the object-carrying box body 301;
[0044] Step 2: Debug the telescopic driving device 201, and then retract the telescopic rod of the telescopic driving device 201;
[0045] Step 3: Place the pin 4 in the object-carrying box body 301, and the quick-connecting cap body of the pin 4 is clamped in the quick-connecting card slot of the telescopic driving device 201;
[0046] Step 4: Start the telescopic driving device 201, extend the telescopic rod to drive the pin 4 to move until it is completely inserted into the ear plate pin hole, thereby completing the assembly of the pin 4.
[0047] In a specific embodiment, the pin pulling process of the pin 4 in the crane support of the present application is as follows:
[0048] Step 1: Clamp the device card shaft 2011 of the telescopic driving device 201 in the box body card slot 3013, and place and fix the telescopic driving device 201 as a whole in the object-carrying box body 301;
[0049] Step 2: Debug the telescopic driving device 201, and then extend the telescopic rod of the telescopic driving device 201 until the quick-connect card slot of the telescopic rod is sleeved on the quick-connect cap body of the pin shaft 4.
[0050] Step 3: Start the telescopic driving device 201 to retract the telescopic rod to drive the pin shaft 4 to move until the pin shaft 4 is completely pulled out of the ear plate pin hole, thereby completing the disassembly of the pin shaft 4.
[0051] Of course, it can be understood that when the number of the telescopic driving devices 201 is sufficient, the telescopic driving devices 201 can be permanently arranged in the object-carrying box body 301 without repeating the installation steps of the telescopic driving devices 201.
