Description

Technical Field

[0001] This utility model belongs to the field of tire manufacturing technology, specifically relating to a gantry frame for cutting and feeding all-steel tire bodies. Background Technology

[0002] In the production of all-steel radial truck tires, steel cord fabric is first cut into carcass cords of fixed dimensions using a 90° right-angle cutting machine. Then, rubber sheets with specific functions (such as structural reinforcement or sealing) are evenly bonded to the surface of the carcass cords using automated bonding equipment. These rubber sheets are standard rolls of rubber compound that have been extruded, cut, and shaped before being tightly wound by an automatic winding device. They are quite heavy. Currently, a gantry crane is typically used to hoist the rolls of rubber onto the unwinding rollers of the bonding equipment for subsequent bonding processes. However, existing gantry cranes can only move the electric hoist along a fixed, single straight line when lifting the rolls. This is inconvenient when the lifting point is not directly below the electric hoist's path. Utility Model Content

[0003] This utility model addresses the shortcomings of the prior art by providing an all-steel tire-type cutting and feeding gantry frame, which is equipped with transverse and longitudinal slide rails, enabling the electric hoist to move in all directions within a certain range, thereby solving the problem that current electric hoists can only move within a fixed straight line range.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A steel tire body cutting and feeding gantry includes two parallel and spaced support hangers. At least two parallel and spaced longitudinal slide rails are connected between the two support hangers. A transverse slide rail is connected between the at least two longitudinal slide rails. The transverse slide rail is slidably connected to each longitudinal slide rail. An electric hoist is slidably connected to the lower part of the transverse slide rail. A wire storage assembly for storing the wires supplying power to the electric hoist is provided on one side of the transverse slide rail and on one side of one of the longitudinal slide rails.

[0006] Preferably, the vertical cross-sectional structure of the longitudinal slide rail and the transverse slide rail is the same, both including rectangular cavities and semi-circular cavities distributed vertically, and a sliding groove is provided on the lower side of the semi-circular cavity.

[0007] Preferably, a slider is slidably connected inside the semi-circular cavity, a slide rod is connected to the lower end of the slider, the slide rod is slidably connected to the slide groove, and the slide rod is connected to a corresponding transverse slide rail or electric hoist.

[0008] Preferably, the ends of the longitudinal slide rail and the transverse slide rail are provided with cover plates.

[0009] Preferably, the longitudinal slide rail is a segmented structure composed of multiple slide rail units connected in series, and a detachable splicing structure is provided between each two adjacent slide rail units.

[0010] Preferably, the splicing structure is provided on a positioning block on one section of the slide rail unit, and the positioning block is connected to the rectangular cavity of the adjacent slide rail unit and locked in place by bolts.

[0011] Preferably, an L-shaped positioning component is provided at the connection between the longitudinal slide rail and the support hanger, and the L-shaped positioning component is connected to the longitudinal slide rail and the support hanger by screws.

[0012] Preferably, the support bracket is provided with mounting holes for fixing.

[0013] Preferably, the wire storage assembly includes two end plates, each end plate is provided with a fixing ring, a steel wire rope is connected between the two fixing rings, and multiple hooks are slidably connected on the steel wire rope.

[0014] Preferably, one end of the fixing ring is connected to a screw, and the end of the screw passes through a fixing hole provided on the end plate and is threaded with a nut.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The electric hoist in this utility model can move left and right along the horizontal slide rail, and the horizontal slide rail can drive the electric slide rail to move forward and backward, thereby realizing the all-round movement of the electric hoist within a certain range, solving the problem that the electric hoist can only move within a fixed straight line range, and meeting the use requirements of film hoisting and loading.

[0017] (2) This utility model uses two sets of wire storage components to store the wires that power the electric hoist, which can effectively prevent the wires from dragging directly on the ground, eliminate safety hazards, and extend the service life of the wires.

[0018] (3) This utility model can adjust the length of the longitudinal slide rail by increasing or decreasing the number of individual slide rail units, thereby expanding the movable range of the electric hoist and making it highly practical. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1As shown, a steel tire-mounted cutting and feeding gantry crane includes two parallel, spaced-apart support hangers 1. At least two parallel, spaced-apart longitudinal slide rails 2 connect the two support hangers. L-shaped positioning parts 13 are provided at the connection points between the longitudinal slide rails and the support hangers. The L-shaped positioning parts are assembled and connected to the longitudinal slide rails and support hangers using screws 21, facilitating the assembly and disassembly of the longitudinal slide rails and support hangers. The support hangers are provided with mounting holes 14 for fixing, facilitating effective fixation of the support hanger's position and improving the overall stability of the gantry crane structure. A transverse slide rail 3 connects the at least two longitudinal slide rails, slidably connecting to each longitudinal slide rail. The transverse slide rails are perpendicular to the longitudinal slide rails. An electric hoist 4 is slidably connected to the lower part of the transverse slide rail. The electric hoist can move left and right along the transverse slide rail, while the transverse slide rail can drive the electric hoist to move forward and backward, thus achieving omnidirectional movement of the electric hoist within a certain range, solving the current problem that electric hoists can only move within a fixed straight line. Since the electric hoist requires power via the wire 22 during operation, wire storage components are provided on one side of the transverse slide rail and on one side of one of the longitudinal slide rails to store the wire 22, preventing the wire from dragging directly on the ground, which not only poses a safety hazard but also affects the lifespan of the wire. In this embodiment, the electric hoist is a DHS type chain electric hoist (electric lifting machine) with a lifting capacity of 5 tons.

[0030] Combination Figure 2 and Figure 4 As shown, the vertical cross-sectional structures of the longitudinal and transverse slide rails are identical, each including vertically distributed rectangular cavities 5 and semi-circular cavities 6. A groove 7 is provided on the lower side of the semi-circular cavity, and a slider 8 is slidably connected within the semi-circular cavity. The shape and size of the slider match the semi-circular cavity. A sliding rod 9 is connected to the lower end of the slider, and the sliding rod is slidably connected to the groove. The sliding rod is connected to the corresponding transverse slide rail or electric hoist to ensure the stability of the electric hoist during movement and operation. Cover plates 10 are provided at the ends of the longitudinal and transverse slide rails. These cover plates serve as limiters, preventing the slider from detaching from one end of the longitudinal or transverse slide rail.

[0031] like Figure 1 and Figure 5 As shown, the longitudinal slide rail is a segmented structure composed of multiple slide rail units 201 connected in series. A detachable splicing structure is provided between each pair of adjacent slide rail units. By increasing or decreasing the number of slide rail units, the length of the longitudinal slide rail can be adjusted, making it highly practical. The splicing structure is located on a positioning block 11 on one of the slide rail units. The positioning block engages with the rectangular cavity of the adjacent slide rail unit and is locked in place by bolts 12, ensuring the stability and robustness of the splicing structure.

[0032] like Figure 1 and Figure 3As shown, the wire storage assembly includes two end plates 15, each end plate is provided with a fixing ring 16, and a steel wire rope 17 is connected between the two fixing rings. Multiple hooks 18 are slidably connected on the steel wire rope. The hooks can be cable-specific hooks, such as plastic material with a certain degree of elasticity. The wires can be suspended in the hooks to play a certain clamping and fixing role. One end of the fixing ring is connected to a screw 19. The end of the screw passes through the fixing hole provided on the end plate and is threaded with a nut 20 for easy disassembly and maintenance.

[0033] The working principle of this utility model is as follows:

[0034] like Figures 1 to 5 As shown, since the electric hoist 4 can move left and right along the transverse slide rail 3, and the transverse slide rail 3 can move back and forth along the longitudinal slide rail 2, when lifting materials, the operator can simply pull the hook of the electric hoist 4 to move it directly above the material, making operation simple and convenient. During the movement of the electric hoist 4, the guide wire 22 will move synchronously. At this time, the redundant guide wires 22 between each hook 18 will be straightened to meet the usage requirements, effectively avoiding the situation of the guide wires dragging on the ground.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
