[0031] This embodiment provides a new frame-type tire pressing machine, which can press tires for gantry cranes. It reduces the space occupied by the tire pressing machine by optimizing the push rod structure of the tire pressing machine; the tire is automatically pushed forward by the bottom automatic hydraulic push rod, and the safety risk is effectively reduced, and the construction efficiency is improved; the mold cylinder sleeve that meets the tire specifications is made---the tire support tooling, and the tire is placed on the tooling during pressing, so that the wheel hub bearing is suspended and the bearing is protected. The tire is placed stably, easy to align, and not easy to tip over.

[0032] like Figure 1 As shown, the tire calendering machine for gantry crane in this embodiment is mainly composed of a frame assembly 1, a calendering assembly 2, a hydraulic system 3 and an electrical control system 4.

[0033] The frame assembly 1 is in the shape of a hexahedron. Figure 2 As shown, a hexahedron consisting of 12 prisms, including a horizontal bar 1-1, four vertical beams 1-3 and four horizontal beams 1-5, is formed. In order to make the hexahedron consisting of 12 prisms strong and stable, a connecting plate 1-2, a lower support beam 1-4, an upper support beam 1-6, and a supporting side beam 1-7 are also provided; there is a guardrail track 1-8 between the two horizontal bars 1-1 below, and a sliding tray 1-9 slides on the guardrail track 1-9; a side shelf 1-10 is also provided on the lower side of the frame assembly 1.

[0034] The tire pressure assembly 2 is as follows Figure 3As shown: it includes a sliding track 2-1, a tire pressing slider 2-2, a guide rod 2-3, a meniscus 2-4, a tire pressing plate 2-5, and a tire supporting tooling 2-6.

[0035] The sliding track 2-1 is welded to the frame assembly 1 and adopts a double-track structure.

[0036] The tire pressing slider 2-2 adopts a frame structure and includes left and right tire pressing sliders distributed in two tracks of the sliding track 2-1.

[0037] The guide rod 2-3 includes left and right guide rods which are respectively arranged under the left and right tire pressing sliders and slide in the double rails of the sliding track 2-1.

[0038] The meniscus 2 - 4 includes left and right meniscus respectively arranged under the left and right guide rods.

[0039] The tire beating plate 2-5 is annular, and the left and right guide rods are respectively opposite to the tire beating plate 2-5.

[0040] The tire supporting tool 2-6 is arranged in the center of the tire pressing plate 2-5, and a device for supporting the wheel hub is arranged in the center.

[0041] In this embodiment, the sliding track 2-1 is an open structure at both ends. The contact portion of the tire pressing slider 2-2 and the sliding track 2-1 is connected by a sliding friction block, and a fulcrum that is effectively connected to the tire pressing cylinder is designed at the bottom. A guide hole is provided on the tire pressing slider 2-2, and the guide rod 2-3 guide structure that can effectively pass through the guide rod 2-3 of the tire pressing slider 2-2 is installed in the guide hole. A connecting fulcrum that can effectively connect the tire pressing slider 2-2 with the translation cylinder is provided on the side of the tire pressing slider 2-2. The meniscus 2-4 is designed according to the size of the pressed tire so that the meniscus 2-4 can effectively contact the position of the pressed tire; a fulcrum that can effectively connect to the tire pressing cylinder is provided on the top of the meniscus 2-4; and a connecting hole that is connected to the guide rod 2-3 so that the meniscus 2-4 is always in a vertical state with the pressed tire is provided on the meniscus 2-4.

[0042] In this embodiment, the meniscus 2-4 is connected by the top of two downward pressure cylinders, and is like a crescent-shaped steel block; the tire pressing plate 2-5 is an independently made steel plate with a notch at the front end, which can be put up and down separately, and is not connected to the accessories on the tire pressing machine. Due to its large area, it can ensure that the downward pressure of the top pressure cylinder is evenly distributed on the tire when removing the tire, which neither damages the tire nor is it convenient to press down. When pressing the tire, the top pressure cylinder drives the meniscus 2-4 to press down on the tire pressing plate 2-5, and the tire pressing plate 2-5 is placed above the tire. Sometimes when there is no tire pressing plate 2-5, the meniscus 2-4 can also be used for emergency tire pressing, but the tire pressing efficiency is low and it is easy to damage the tire.

[0043] The opening of the annular beading plate 2-5 is so that when the plate is placed, the hub axle head can pass through the gap to enter the middle of the plate, without lifting the plate high and inserting it from the top into the center. The empty square box on the edge of the opening is used to facilitate the forklift's fork to carry it back and forth. The annular beading plate 2-5 is relatively heavy; the tire support tooling is a combination of the hub, spokes, and rim that supports the tire before it is installed; the middle of the tire support tooling is indeed a ring body that supports the hub, but for easy handling, "square boxes" of the forklift's fork are welded on both sides of the tooling, and the contact area between the top of the ring body and the hub is widened to make it stable.

[0044] In this embodiment, the hydraulic system 3 is as follows Figure 4 As shown: it includes a bottom clamping cylinder assembly 3-1, a bottom telescopic cylinder assembly 3-2, a tire pressing cylinder assembly 3-3, a translation cylinder assembly 3-4, and a hydraulic pump station 3-5; the tire pressing cylinder assembly 3-3 includes left and right tire pressing cylinders respectively installed in the frame structure of the left and right tire pressing sliders, and the push rod of the tire pressing cylinder is connected to the meniscus 2-4; the translation cylinder assembly 3-4 includes an upper translation cylinder and a lower translation cylinder, one end of each translation cylinder is connected to the translation slider, and the other end is connected to the sliding track bracket, and the two groups of translation cylinders form an inner cross posture; the bottom telescopic cylinder assembly 3-2 is installed on the lower side of the bottom sliding tray, one side is connected to the bottom sliding tray, and the other side is connected to the tire pressing machine frame fixed point; the bottom clamping cylinder assembly 3-1 is installed on the inner side of the bottom sliding tray clamping tooling; the hydraulic pump station 3-5 is connected to each cylinder assembly through a hydraulic pipeline, and the coordinated action of each cylinder is realized through the hydraulic cylinder. The electrical control system 4 controls various movements.

[0045] The detailed structure is as follows:

[0046] 1. The tire pressing frame is a welded frame structure, the structural strength meets the requirements of tire pressing, and is suitable for pressing tires of various sizes (18-25; 21-25; 21-35);

[0047] 2. The rear inspection door is designed with a hinge structure to facilitate equipment maintenance;

[0048] 3. The front part is designed with an automatic lifting safety door, which is connected to the frame through a matching track. A hook is designed on the top of the safety door, and a push rod is designed on the door frame. The electric winch is connected to the hook through the push rod and is lifted and lowered by the electric winch. Limit devices are designed on the upper and lower parts of the door frame respectively, and the safety door can stop immediately when it reaches the upper and lower limit positions.

[0049] 4. Design a bottom sliding tray, which is connected to the tire press frame by a sliding structure. A tire support tool is placed in the center of the tray to support the tire. A telescopic cylinder is designed at the bottom of the tray, which can move the tire forward and backward inside the tire press and always keep the tire in the center of the tire press during tire pressing.

[0050] 5. Design an external storage table, which is welded on the left and right sides of the tire pressing machine frame, to effectively store various tools and components required for tire replacement;

[0051] The tire pressure assembly 2 is as follows Figure 3 As shown, it includes a sliding track 2-1, a tire pressing slider 2-2, a meniscus 2-4, a guide rod 2-3, a tire pressing plate 2-5 and a tire supporting tooling 2-6.

[0052] The tire calendering assembly 2 is designed with double sliding tracks, and the left and right tire calendering sliders are arranged on both sides, so that when the tire calendering machine adjusts the position of the tire calendering slider, it does not extend outside the tire calendering machine frame, which reduces the space occupied by the tire calendering machine and reduces the risk of the slider cylinder being hit. The tire calendering assembly is as follows:

[0053] The sliding track 2-1 adopts a double-track structure, which is more stable and reliable during tire pressing. The sliding track 2-1 is welded to the frame assembly 1, and the track is designed with an open structure at both ends to facilitate the inspection and maintenance of the tire pressing slider.

[0054] The tire pressing slider 2-2 adopts a frame structure, and the contact part with the track is connected with a sliding friction block (the friction block is replaceable) to increase the service life of the track and the slider; a special fulcrum is designed at the bottom of the slider, which can be effectively connected with the tire pressing cylinder.

[0055] In this embodiment, a guide hole is designed on the tire-pressing slider 2-2, and a guide structure of a guide rod 2-3 is added, so that the guide rod 2-3 can effectively pass through the tire-pressing slider 2-2; a connecting fulcrum is designed on the side of the tire-pressing slider 2-2, which can realize the effective connection between the tire-pressing slider 2-2 and the translation cylinder, and can effectively protect the translation cylinder piston rod from being damaged by the lateral force for a long time during tire pressing.

[0056] The meniscus 2-4 is designed according to the size of the pressed tire, so that the meniscus 2-4 can effectively contact the position of the pressed tire; a special fulcrum is designed on the top of the meniscus 2-4, which can be effectively connected to the tire pressing cylinder; a special connecting hole is designed for the meniscus, and by connecting with the guide rod, the meniscus 2-4 is always in a vertical state with the pressed tire.

[0057] The guide rod 2-3 is designed to be fixed with the meniscus, and is connected with the tire pressing slider 2-2, and is in a sliding state, so that the meniscus 2-4 and the tire pressing slider 2-2 are always in an effective limit position.

[0058] The special beading plate is designed in a ring shape with beading points on both sides. During beading, the pressure is transmitted through the beading plate to reduce the stress concentration area and reduce the possibility of tire damage. The tire support tooling design effectively connects the tire and the tire support tooling to improve the stability during the beading process and protect the internal bearings from damage.

[0059] Hydraulic system 3 Figure 4 As shown, it includes a tire-pressing cylinder assembly 4-3, a translation cylinder assembly 4-4, a bottom telescopic cylinder assembly 4-2, a bottom clamping cylinder 4-1, a hydraulic pipeline, and a hydraulic pump station 4-5.

[0060] The tire pressing cylinder assembly 4-3 is divided into a left cylinder and a right cylinder. One end of the left and right cylinders is connected to the tire pressing slider 2-2, and the other end is connected to the meniscus 2-4. The meniscus is pressed downward together by the extension and contraction of the left and right cylinders, the configuration of the tire pressing cylinders on both sides, and the distribution valve.

[0061] The translation cylinder assembly is divided into an upper translation cylinder and a lower translation cylinder. One end of the upper and lower translation cylinders is connected to a translation slider, and the other end is connected to a sliding track bracket. The two groups of cylinders form an inner cross posture, so that the cylinders are always on the inner side of the tire pressing machine frame when in action, reducing the occupied area, achieving tire pressing in different size modes, ensuring that the meniscus is always in a suitable position, and flexible operation. In this embodiment: the translation slider is below the bottom of the tire pressing machine, and the translation cylinder is installed behind the slider, that is, the sliding tray. It belongs to the tire pressing assembly.

[0062] The bottom telescopic cylinder assembly 4-1 is installed on the lower side of the bottom sliding tray, one side of which is connected to the tray and the other side is connected to the fixed point of the tire pressing machine frame. It is mainly used to automatically adjust the sliding tray to the determined position for tire pressing after the tire is placed inside the tire pressing machine through the telescopic cylinder.

[0063] The bottom clamping cylinder assembly is installed on the inner side of the bottom sliding tray. After the tire and tooling are placed on the tray, the tooling is clamped by the clamping cylinder to ensure safety during the tire pressing process.

[0064] Hydraulic pump station and hydraulic pipelines. The hydraulic pump station is connected to each cylinder assembly through hydraulic pipelines, and the coordinated action of each cylinder is achieved through the hydraulic cylinders.

[0065] In this embodiment, a gantry crane tire calender is designed with a dedicated electrical control system, which realizes various actions of the hydraulic system through a PLC controller and a touch screen to complete the entire calendering process; after the tire is placed inside the calender by a forklift, the control system flow is as follows:

[0066] Select the tire type → push the tire to the center position with the telescopic cylinder → close the safety door → start the clamping cylinder → start the translation cylinder → start the tire-flattening cylinder → retract the tire-flattening cylinder → release the clamping cylinder to open the safety door → retract the telescopic cylinder.

[0067] When using this embodiment, the detailed tire pressing process is as follows:

[0068] 1. Place the prepared tire support tooling on the bottom tray of the tire press → 2. Select the corresponding wheel hub assembly (hub, spoke, rim assembly) type, and use a forklift to place the wheel hub assembly directly above the support tooling → 3. Select the tire type, use a forklift to place the rubber tire directly above the wheel hub assembly, and insert a large part of the wheel hub (the remaining part needs to be pressed in by the tire press) → 4. Place the upper side pressure ring of the tire (a ring-shaped steel ring, equivalent to a large gasket) directly above the tire and concentric with the tire → 5. Use a forklift to fork the tire press plate above the rubber tire, that is, above the upper side pressure ring, and try to be concentric with the tire and the pressure ring → 6. The telescopic cylinder pushes the pallet, and the pallet drives the preliminarily assembled tire assembly to the center of the tire press (in the middle of the bottom clamping cylinder, that is, the center of the entire tire press, to ensure that the outer ring of the tire will not scrape against the inner frame of the tire press during tire pressing) →7. Close the safety door→8. Start the clamping cylinder and clamp the tire support tooling→9. Start the translation cylinder and adjust the top pressure cylinder to the left and right upper position of the tire pressure ring to be pressed→10. Start the top pressure cylinder, drive the meniscus to press down the tire pressing plate, and the tire pressing plate presses down the outer pressure ring, and the pressure ring pushes the entire rubber tire into the wheel hub assembly until the spring ring groove and the sealing ring groove position above the wheel hub are exposed→11. Open the safety door→12. Manually install the tire sealing ring (0-type rubber ring) and the outermost spring ring in turn→13. Close the safety door→14. Return the tire pressing cylinder (top pressure cylinder)→15. Release the clamping cylinder→16. Open the safety door→17. Return the telescopic cylinder of the bottom tray and push the pressed tire assembly out of the tire pressing machine together with the support tooling→18. After the tire is pressed, the forklift transports the tire assembly to the special inflatable cage for inflating. (If the tire pressing operation is not busy, you can also fill the tire in this tire pressing machine, open the safety door, and finally push the tire out.

[0069] The electrical operation and protection system is as follows:

[0070] 1. The protective windows on both sides of the tire pressing machine and the front protective lifting door are equipped with limit sensors. When maintenance is completed or the windows are not closed properly, the touch screen will display an alarm prompt, the PLC control prohibits tire pressing, and the oil cylinder does not move. This effectively prevents the injury to the tire pressing personnel when an accidental tire blowout occurs.

[0071] 2. Gratings are installed on both sides of the front protective door. When someone is under the protective door, the PLC receives the grating signal to prohibit the protective door from falling, effectively protecting the maintenance personnel from being crushed.

[0072] 3. Position sensors are installed at both ends of each oil cylinder. Through PLC and hardware interlocking, each oil cylinder stops moving in advance before reaching the mechanical limit position, effectively protecting the oil cylinder piston rod and oil seal from mechanical damage.

[0073] 4. A gantry crane tire pressing machine adopts two operation modes: "normal" and "maintenance". In the normal mode, if any of the protective windows and protective doors are not closed, the tire pressing will not work; in the maintenance mode, if the protective windows and doors are not closed, the tire pressing machine can be entered to facilitate maintenance and debugging.
