Description

Technical Field

[0001] This application relates to the field of mining truck tire disassembly and repair technology, and in particular to a pot ring disassembly device for mining tire repair. Background Technology

[0002] Mining trucks typically have large body dimensions, and therefore their tires are usually also large. However, the mining environment is complex and the roadbed is covered with scattered ore, so the tires of mining trucks usually wear out quickly, have a short lifespan, and are prone to damage during their service life, requiring multiple repairs.

[0003] Because mining areas are typically located in mountainous regions with underdeveloped infrastructure, they often lack tire disassembly and repair equipment, requiring repairs to be carried out outside the mining area. However, sometimes simple repairs performed on-site can effectively shorten tire repair time and reduce costs, allowing mining trucks to quickly return to normal production.

[0004] The structure of the mining tire is as shown in the instruction manual. Fig. 1-2 As shown, a rim is unidirectionally fitted inside the tire, and a flange is pressed against the tire with a stepped contact on the side of the rim that inserts into the tire. Because mining tires have larger specifications and wall thicknesses, the rims used in these applications include flanges to facilitate tire and rim disassembly and maintenance. During assembly, the rim is inserted from one side of the tire (one side of the rim is wider than the other; the narrower side can pass through the tire, while the wider side presses against the tire sidewall). Fig. 2-3 (As shown in the diagram), then insert the rim between the tire and the rim. Using the steps on the rim, the rim can press the rim against the tire, thereby restricting the tire on the side with the smaller rim width, thus achieving the assembly of the rim and the tire.

[0005] Currently, when tire repair is needed, such as Fig. 3 , 7 As shown, a pry bar is used, with its flat end inserted between the rim and the tire. The tire is then pressed down, causing the step of the rim to detach from the hub (the rim has a notch, but it is not completely closed). This process is repeated circumferentially until the rim and hub are removed by external force. Then the hub is removed from the tire, allowing for tire repair.

[0006] Currently, when using a pry bar to remove the rim, the flat end of the pry bar is difficult to insert smoothly between the tire and the rim because the tire is in close contact with the rim. In addition, when pressing down with the pry bar, the tire surface is concave along with the pry bar because the tire is made of soft rubber, which prevents the rim from being easily separated from the rim by the pry bar. Therefore, tire removal is quite difficult. Summary of the Invention

[0007] In view of the above problems, the present application aims to provide a pot ring dismounting device for mining tire maintenance, which can quickly separate the pot ring from the hub through the connecting member and the supporting member, thereby achieving quick and labor-saving dismounting of the pot ring and the hub, and finally dismounting the tire.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the present application is as follows: a pot ring dismounting device for mining tire maintenance, wherein a hub is sleeved in the tire in one direction, and a pot ring is in contact with the tire on the side where the hub is inserted into the tire; a plurality of screw holes are formed in the hub in the circumferential direction; the dismounting device comprises a connecting member connected to the side edge of the pot ring, and a supporting member connected to the connecting member and in contact with the hub; and the connecting member and the supporting member are hingedly connected.

[0009] Preferably, the connecting member is a hook body sleeved on the side end of the pot ring; the supporting member comprises a driving rod, and a supporting rod is arranged on the bottom end of the driving rod at a certain angle and in contact with the surface of the hub; and the hook body is hingedly connected to the supporting rod.

[0010] Preferably, a positioning protrusion is arranged on one side of the supporting rod and can be positioned and embedded into the screw hole.

[0011] Preferably, a limiting part is arranged at the end of the supporting rod and can be in contact with the hook body at a certain angle of rotation and limit the rotation of the hook body.

[0012] The present application has the following beneficial effects: the dismounting device can be connected to the side edge of the pot ring through the connecting member, and based on the connection, the supporting member is in contact with the hub, and the hub serves as a rotating fulcrum, which can act on the connecting member, thereby separating the pot ring from the hub through the connecting member, thereby achieving quick and labor-saving dismounting of the pot ring and the hub, and finally dismounting the tire.

[0026] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application will be further described below in combination with the drawings and examples.

[0027] Referring to the drawings Figs. 1-12 A pot ring disassembly device for repairing a mining tire is shown. A hub 1 is sleeved in the tire in one direction. The hub 1 is inserted into one side of the tire and is in contact with the pot ring 2 attached to the tire by a step. A plurality of threaded holes 1a are formed in the hub 1 in the circumferential direction. Since the specifications and wall thickness of the mining tire are large, the hub is attached with the pot ring, which facilitates the disassembly and repair of the tire and the hub. When assembling, the hub is inserted from one side of the tire (the hub has a large width on one side and a small width on the other side. The smaller side can be inserted through the tire, while the larger side is in contact with the tire sidewall, as shown in the state Fig. 6 ). Then the pot ring is inserted between the tire and the hub. The hub can press the pot ring against the tire by using the step on the pot ring, thereby limiting the tire on the small side of the hub and achieving the assembly of the hub and the tire.

[0028] In order to solve the problem that it is difficult to insert the flat end of the crowbar between the tire and the pot ring when disassembling the tire using a crowbar, and the surface of the tire is concave along with the crowbar, thereby causing certain operation difficulty when disassembling the tire, the present application is provided with a disassembly device, as shown in Fig. 8-9As shown, it comprises a connecting member connected with the side edge of the pot ring 2, and a supporting member connected with the connecting member and in contact with the hub 1, and the connecting member and the supporting member are hingedly connected. In operation, the connecting member can be connected with the side edge of the pot ring, and on the basis of the connection, the supporting member is in contact with the hub. Since the hub is made of metal, it has high body strength, so when the supporting member is driven to rotate in contact with the hub, it can act on the connecting member, and then the connecting member can separate the pot ring from the hub, so that the pot ring and the hub can be quickly and labor-savingly disassembled, and finally the tire is disassembled.

[0029] Specifically, as shown in the figure, Fig. 8-10 The connecting member is a hook body 3 sleeved on the side end of the pot ring 2, as shown in the figure, Fig. 10 The end of the hook body 3 is flat, which can be easily sleeved on the side wall of the pot ring. The supporting member comprises a driving rod 4, and a supporting rod 5 is arranged at the bottom end of the driving rod 4 at a certain angle and in contact with the surface of the hub 1. The hook body 3 is hingedly connected to the supporting rod 5. In operation, as shown in the figure, Fig. 10 First, the hook body 3 is sleeved on the side edge of the pot ring by external force, and then the driving rod 4 is rotated to make the supporting rod 5 contact the surface of the hub. Under the stable contact of the supporting rod 5 and the hub, the driving rod 4 is driven to rotate again, so as to drive the hook body 3 to move obliquely upward, so as to separate the part of the pot ring (operated by first disassembling from the opening of the pot ring) in contact with the hook body 3 from the hub, and then the whole pot ring can be sequentially disassembled from the hub along the circumference.

[0030] In the process of continuing to drive the driving rod 4 to rotate and lifting the hook body 3 and the pot ring, in order to avoid the problem that the supporting rod 5 moves on the surface of the hub and causes the hook body 3 to separate from the pot ring, as shown in the figure, Fig. 8-9 A positioning protrusion 51 is arranged on one side of the supporting rod 5 and can be positioned and embedded into the stud hole 1a (which is used for connecting the hub with the vehicle body). During the rotation of the driving rod 4, the positioning protrusion 51 is embedded into the corresponding stud hole 1a, and during the process of continuing to drive the driving rod 4 to rotate, the relative positioning of the supporting rod 5 and the hub can be limited, so as to limit the problem that the hook body 3 separates from the side edge of the pot ring.

[0031] Before disassembling the pot ring, since the pot ring and the tire are in a pressed state, in order to facilitate the hook body 3 to be smoothly sleeved on the side edge of the pot ring, as shown in the figure, Fig. 11 A limiting portion 52 is arranged at the end of the supporting rod 5 and can be in contact with the hook body 3 and limit the hook body 3 when rotated by a certain angle. After the hook body 3 is rotated to a certain angle, the back of the hook body 3 is in contact with the limiting portion 52, as shown in the figure, Fig. 11 So as to limit the continuous rotation of the hook body 3. In this state, the axial driving action of the driving rod 4 can drive the hook body 3 to move upward, so as to separate the part of the pot ring in contact with the hook body 3 from the hub. Fig. 11When the hook body 3 is inserted between the tire and the rim, the hook body 3 is clamped on the side of the rim to achieve the fast clamping operation (as indicated by the arrow), and then the driving rod 4 is turned to make the support rod 5 contact the surface of the hub, and the driving rod 4 is continuously turned to lift the rim from the hub by the hook body 3, thereby achieving the fast disassembly operation.

[0032] Since the hook body 3 still has a certain thickness, when the external force is inserted between the tire and the rim, the end of the hook body 3 and the side of the rim are prevented from slipping, as shown in Fig. 12 The end of the hook body 3 is hinged with an insertion plate 31, which can be inserted between the tire and the rim before the hook body 3, and is pressed by the insertion plate 3 under the pressing action of the two, so that the hook body 3 can be quickly inserted by the insertion plate during the process of inserting the hook body 3, and the problem of slipping between the end of the hook body 3 and the side of the rim is avoided.

[0033] The principle of the present application is that when the tire is disassembled, the hook body 3 is rotated to contact the limiting portion 52 of the support rod 5 to limit the rotation of the hook body 3 relative to the driving rod 4, and then an axial force is applied along the driving rod 4 to drive the insertion plate at the end of the hook body 3 to be inserted between the tire and the rim to limit and guide the hook body 3, and then the driving rod 4 is continuously applied to make the hook body 3 clamped on the side of the rim, and then the driving rod 4 is rotated to make the support rod 5 contact the surface of the hub and make the positioning protrusion 51 embedded in the stud hole 1a to limit the position of the support rod 5, and then the driving rod 4 is continuously rotated, and under the action of the hub as a fulcrum, the hook body 3 is lifted and the rim is separated from the hub, and then the hub is separated from the tire in one direction, thereby achieving the fast disassembly operation of the tire.

[0034] The basic principles, main features and advantages of the present application are shown and described above. Various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed application.
