Description

Technical Field

[0001] This utility model relates to auxiliary devices for tire production equipment, specifically a special trolley for replacing all-steel triangular rubber-coated composite drums. Background Technology

[0002] The bonding station layout of the all-steel triangular adhesive bonding production line is very compact. The triangular adhesive bonding molding drum also needs to be frequently replaced to meet the needs of different product specifications. Various types of pipelines (compressed air pipes, water pipes, exhaust pipes, etc.) are arranged in the air above the workshop, making it unsuitable for gantry cranes. The space near the bonding station is even narrower, making it impossible to install a cantilever crane. The triangular adhesive bonding molding drum weighs about 230KG. Without auxiliary lifting equipment, it is difficult and unsafe to replace the triangular adhesive bonding molding drum by simply carrying it by hand.

[0003] To address the problems of inconvenience, low efficiency, and safety issues associated with replacing triangular adhesive bonding drums, a utility model patent with authorization announcement number CN218084282U proposes a "Transfer Device for Hot-Pattern Replacing and Bonding Drums with All-Steel Triangular Adhesive Cores." The technical solution includes a trolley, a lifting platform, and a bonding drum fixture. The trolley is a flatbed structure with a lifting platform and lifting mechanism on its upper part. The bonding drum fixture is mounted on the lifting platform and slidably connected to it. The bonding drum fixture has at least one support surface and a positioning structure.

[0004] The utility model "All-steel triangular rubber core hot-pressing and bonding drum transfer device" solves the problem of handling and lifting the triangular rubber bonding drum well, but it cannot ensure that the connecting flange end face of the triangular rubber bonding drum and the connecting flange end face of the bonding host are kept parallel, resulting in low precision of the fit between the two flange end faces and unsmooth assembly. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a special trolley for replacing the all-steel triangular adhesive patch composite drum with more optimized performance.

[0006] A technical solution for replacing the all-steel triangular adhesive-bonded composite drum with a special trolley that can solve the existing technical problems includes a four-wheeled handcart. The four-wheeled handcart has a lifting platform mounted on a foot-operated scissor lift mechanism. The lifting platform has a triangular adhesive-bonded composite drum fixture mounted via a sliding mechanism. The difference is:

[0007] 1. The sliding mechanism includes left and right slide rails, and front and rear slide blocks are slidably installed on each slide rail. A sliding platform is installed on the front, rear, left and right slide blocks. At least one slide block is provided with a locking element to fasten it to the corresponding slide rail and prevent the sliding platform from moving forward or backward.

[0008] 2. The triangular adhesive composite drum fixture includes roller assembly I and roller assembly II, which can lift the triangular adhesive composite drum from the front and rear. Roller assembly I is mounted on a sliding platform via a hand-cranked scissor lift mechanism, and roller assembly II is mounted on the sliding platform.

[0009] 3. The hand-cranked scissor lift mechanism can adjust the lifting height of roller assembly I to be higher, level, or lower than the lifting height of roller assembly II.

[0010] Furthermore, the roller assembly I includes a flat plate mounted on a hand-cranked scissor lift mechanism, and the flat plate is provided with left and right symmetrical support rollers I; the roller assembly II includes left and right symmetrical support rollers II mounted on an arc frame; the axes of support rollers I and II on the same side are in the same vertical plane.

[0011] Furthermore, the arc-shaped frame is equipped with cable ties for binding triangular adhesive tape to form a molded drum.

[0012] Furthermore, the pushing direction of the four-wheeled handcart is perpendicular to the sliding direction of the sliding mechanism.

[0013] The beneficial effects of this utility model are:

[0014] In addition to the traditional transportation and lifting functions, the special trolley for replacing the all-steel triangular adhesive-coated composite drum has an innovative function: roller assembly I and roller assembly II jointly support the triangular adhesive-coated composite drum, and the height of roller assembly I relative to roller assembly II is changed by a hand-cranked scissor lift mechanism to correct the parallelism between the connecting flange end face on the front side of the triangular adhesive-coated composite drum and the connecting flange end face of the bonding host, making the fitting between the two connecting flanges more precise and smooth.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] This utility model relates to a special trolley for replacing all-steel triangular adhesive composite drums. It includes a four-wheeled handcart 1 with a load-bearing capacity exceeding 500KG. The four-wheeled handcart 1 is equipped with a lifting platform 3 mounted on a foot-operated scissor lift mechanism 2. By stepping on the hydraulic pedal 2-1, the cylinder rod of the hydraulic cylinder 2-2 is extended. This cylinder rod reduces the fork angle of the cross linkage, causing the lifting platform 3 to rise. When lowering the lifting platform 3, the pressure relief valve is opened to release the oil pressure in the hydraulic cylinder, thus lowering the height of the lifting platform 3. The length direction of the lifting platform 3 is the same as the pushing direction (left and right) of the four-wheeled handcart 1. The lifting platform 3 is equipped with a triangular adhesive composite drum fixture mounted via a sliding mechanism. The sliding direction of the sliding mechanism is perpendicular to the pushing direction (forward and backward). Figure 1 , Figure 2 As shown.

[0021] The sliding mechanism includes left and right symmetrical slide rails 4 (forward and backward rods). Each slide rail 4 is mounted on the base plate of the lifting platform 3 via front and rear bases. Front and rear slide blocks 5 are slidably mounted on each slide rail 4. Sliding platforms 6 are mounted on the front, rear, left, and right slide blocks 5. The front of each sliding platform 6 has left and right openings. A hand-operated locking piece 7 is provided on one of the front slide blocks 5 to lock it onto the corresponding slide rail 4, thereby fixing the forward and backward movement position of the sliding platform 6. Figure 1 , Figure 2 As shown.

[0022] The triangular adhesive composite drum fixture includes a roller assembly I (front-mounted) and a roller assembly II (rear-mounted) for supporting the triangular adhesive composite drum 9 (the drum's axis is in the front-to-back direction, and the connecting flange I9-1 is located on the front end face of the drum). The roller assembly II includes an arc-shaped frame 15 mounted on the rear of the sliding platform 6. The arc-shaped frame 15 includes two arc-shaped plates connected by screws, one front and one rear. Symmetrical left and right support rollers II 13 (mounted via axles) are provided between the two arc-shaped plates. A cable tie box 10 (with cable ties wound inside) is located at the bottom of one side (left or right) of the arc-shaped frame 15, and a cable tie hanging rod 16 is located at the bottom of the other side (right or left) of the arc-shaped frame 15. Figure 1 , Figure 2 As shown.

[0023] The roller assembly I is located at the front of the sliding platform 6 and includes a flat plate 11 (left and right orientation) mounted on a hand-cranked scissor lift mechanism 8. The hand-cranked scissor lift mechanism 8 includes two cross-hinged connecting rods. The cross connecting rods are located inside the opening of the sliding platform 6. The lower left and right ends of the cross assembly are below the sliding platform 6, with the lower right end hinged in a fixed position and the lower left end hinged to a sliding sleeve. The sliding sleeve is slidably mounted on the sliding rod. The upper left and right ends of the cross connecting rods are above the sliding platform 6, with the upper right end hinged in a fixed position and the upper left end hinged to a nut. The nut is screwed onto... On the lead screw 8-2, the lead screw 8-2 is driven to rotate by the handwheel 8-1. The nut moves left and right on the lead screw 8-2, thereby changing the fork angle of the cross linkage, thus driving the plate 11 to move up and down above the sliding platform 6. The plate 11 is provided with left and right symmetrical support rollers I 12 (mounted by wheel seats). The axes of the support rollers I 12 and II 13 on the same side are in the same vertical plane. The lifting and lowering movement of the plate 11 can make the lifting height of the left and right support rollers I 12 higher than, level with, or lower than the lifting height of the left and right support rollers II 13. Figure 1 , Figure 2 As shown.

[0024] like Figure 3 As shown, the process steps for installing the triangular adhesive composite drum 9 using this utility model are as follows:

[0025] 1. In the storage area of ​​the triangular adhesive composite drum 9, use a crane to hoist a triangular adhesive composite drum 9 onto the triangular adhesive composite drum fixture. The front drum surface of the triangular adhesive composite drum 9 is supported by the left and right support rollers I12, while the rear drum surface of the triangular adhesive composite drum 9 is supported by the left and right support rollers II13. Pull out the straps to securely bind the triangular adhesive composite drum 9.

[0026] 2. Push the triangular adhesive composite drum 9 to the side of the bonding host 14 using a four-wheeled handcart 1. There are two limiting grooves 17 (left and right) on the ground next to the bonding host 14. Push the front and rear wheels of each side of the four-wheeled handcart 1 into the corresponding limiting grooves 17, and the installation position of the triangular adhesive composite drum 9 will be basically aligned. Loosen the straps to untie the triangular adhesive composite drum 9.

[0027] 3. Step on the hydraulic pedal 2-1 to raise the lifting platform 3, i.e., the height of the triangular adhesive composite drum 9, through the foot-operated scissor lifting mechanism 2, so that the connecting flange I 9-1 at the front end of the triangular adhesive composite drum 9 is aligned with the connecting flange II 14-1 of the bonding host 14.

[0028] 4. Rotate handwheel 8-1 to adjust (raise or lower) the height of connecting flange I 9-1 via hand-cranked scissor lift mechanism 8, and correct the parallelism between the end faces of connecting flange I 9-1 and connecting flange II 14-1.

[0029] 5. Loosen the locking piece 7 to release the locking of the sliding platform 6, and push the triangular adhesive composite drum 9 forward by hand to bring the connecting flange I 9-1 closer to the connecting flange II 14-1.

[0030] 6. Rotate the triangular adhesive molding drum 9 by hand to align the bolt holes between connecting flange I 9-1 and connecting flange II 14-1.

[0031] 7. The operation of fixing connecting flange I9-1 and connecting flange II14-1 with bolts and installing triangular adhesive tape to form the molded drum 9 is completed.
