Description

Technical Field

[0001] This utility model relates to the technical field of rock wool production equipment, specifically to a rock wool transfer trolley. Background Technology

[0002] Rock wool boards, as a type of artificial inorganic fiber material with properties such as light weight, low thermal conductivity, and non-combustibility, are widely used in the building insulation industry. During the processing and production of rock wool boards, they need to be transferred between different stages using conveyor equipment; therefore, conveyor trolleys are key auxiliary equipment for ensuring production efficiency.

[0003] In existing technologies, most rock wool board transfer trolleys employ fixed-structure support frames, using side baffles and pressing mechanisms to limit the rock wool boards. For example, Chinese patent CN221418364U discloses a rock wool board production and processing transfer trolley that uses the lifting drive of a side support protection mechanism to open a protective curtain, which, in conjunction with a pressing positioning mechanism, wraps and secures the rock wool boards. However, the carrying area of ​​such equipment is fixed, only suitable for rock wool boards of a specific width. When dealing with wider rock wool boards, different specifications of transfer trolleys need to be used, resulting in poor equipment versatility and increased transfer costs. Furthermore, some transfer trolleys have fixed clamping structures, which can easily obstruct the operating space when loading rock wool boards, reducing loading efficiency. Utility Model Content

[0033] Example 1:

[0034] The main structure of this embodiment is as follows: Figures 1-3 As shown, including

[0035] The trolley body 1 has side plates 2 connected to both ends, and a pusher frame 3 is connected to the side plates 2;

[0036] The clamping assembly is connected to the trolley body 1. When the clamping assembly is in use, the moving end of the clamping assembly moves in the vertical direction to limit the position of the rock wool board.

[0037] The enclosing assembly, connected to the trolley body 1, includes a flip plate 4, a positioning plate 5, a limiting plate 6, and a self-locking component 7. Two symmetrically arranged flip plates 4 are rotatably connected to a notch in the trolley body 1. The positioning plate 5 is slidably connected to the opposite side of the flip plates 4. The self-locking component 7 is connected to both ends of the flip plates 4. The symmetrically arranged limiting plates 6 are connected to two side plates 2. The limiting plates 6 have mating grooves 8. The self-locking component 7 is slidably connected to the limiting plates 6. When the enclosing assembly is in use, the flip plates 4 can rotate and switch between horizontal and vertical states to increase the load-bearing area of ​​the trolley body 1 and accommodate rock wool boards of different widths.

[0038] The specific implementation process is as follows: Side plates 2 are fixed at both ends of the trolley body 1, and pusher frames 3 are welded onto the side plates 2; the two flip plates 4 of the enclosed assembly are rotatably connected to the notch of the trolley body 1 through hinges, and the positioning plate 5 is slidably connected to the opposite side of the flip plates 4 through a slide rail; the limiting plate 6 is symmetrically welded to the side plate 2, and the self-locking component 7 is installed at both ends of the flip plate 4 and slides to fit the mating groove 8 of the limiting plate 6. When transporting rock wool boards of regular width, the flip plate 4 is rotated to a vertical state and locked by the self-locking component 7 and the mating groove 8. At this time, the flip plate 4, the positioning plate 5, the side plate 2 and the trolley body 1 form a semi-enclosed structure to prevent the rock wool board from tipping over; when transporting wide rock wool boards, the self-locking component 7 is released, and the flip plate 4 is rotated to a horizontal state and coplanar with the trolley body 1. Side protection is achieved by sliding adjustment of the positioning plate 5, and the bearing area is expanded to the coverage area of ​​the flip plate 4.

[0039] Example 2:

[0040] This embodiment further defines the structure of the self-locking component 7 based on the above embodiments, such as... Figure 3 As shown, the self-locking component 7 consists of a fixed cylinder 9, a moving rod 10, a first threaded rod 11, an adjusting handle 12, and a locking block 13. The fixed cylinder 9 is connected to the flip plate 4. One end of the first threaded rod 11 is rotatably connected to the fixed cylinder 9, and the other end of the first threaded rod 11 is connected to the adjusting handle 12. The moving rod 10 is threadedly connected to the first threaded rod 11. The moving rod 10 is slidably engaged with the fixed cylinder 9 and is connected to the locking block 13. The locking block 13 engages with the mating groove 8. By driving the locking block 13 to engage or disengage with the mating groove 8 through threaded transmission, the flip plate 4 is fixed in a horizontal / vertical state, ensuring structural stability after state switching.

[0041] The specific implementation process is as follows: the fixing cylinder 9 of the self-locking component 7 is welded to both ends of the flip plate 4; one end of the first threaded rod 11 is rotatably connected to the fixing cylinder 9 via a bearing, and the other end is welded to the adjusting handle 12; the moving rod 10 is threadedly connected to the first threaded rod 11 and slides against the inner wall of the fixing cylinder 9; a locking block 13 is welded to the end of the moving rod 10, and the locking block 13 is adapted to the shape of the mating groove 8 of the limiting plate 6. Rotating the adjusting handle 12 drives the first threaded rod 11 to rotate, and the moving rod 10 slides along the axial direction of the fixing cylinder 9, pushing the locking block 13 into the mating groove 8, thereby locking the flip plate 4; rotating the adjusting handle 12 in the opposite direction disengages the locking block 13 from the mating groove 8, allowing the flip plate 4 to rotate freely. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0042] Example 3:

[0043] This embodiment, based on the above embodiment, further adds a support block, such as... Figure 1 , Figure 2 As shown, the side of the flip plate 4 away from the positioning plate 5 is connected to symmetrically arranged support blocks. A telescopic device 14 is connected to the support blocks, and a connecting block 15 is connected to the telescopic end of the telescopic device 14. The connecting block 15 is connected to the positioning plate 5. A groove is provided on the flip plate 4 for the connecting block 15 to pass through and slide. The telescopic device 14 drives the positioning plate 5 to slide along the flip plate 4, compensating for the protection range after the flip plate 4's state switch, and ensuring lateral restraint of rock wool boards of different widths.

[0044] The specific implementation process is as follows: Symmetrical support blocks are welded to the side of the flip plate 4 away from the positioning plate 5. A telescopic device 14, such as an electric push rod, is bolted to the support blocks. The telescopic end of the telescopic device 14 is welded to a connecting block 15, which passes through a groove on the flip plate 4 and is bolted to the positioning plate 5. When the telescopic device 14 is activated, its telescopic end drives the positioning plate 5 to slide along the groove of the flip plate 4 via the connecting block 15. When the flip plate 4 is in a horizontal state, the positioning plate 5 slides to fit against the side of the rock wool board, replacing the flip plate 4 in its vertical state to achieve side protection. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0045] Example 4:

[0046] This embodiment further defines the structure of the clamping component based on the above embodiments, such as... Figure 1 , Figure 2 As shown, the clamping assembly includes a second threaded rod 16, one end of which is rotatably connected to the trolley body 1, and the other end of the second threaded rod 16 is connected to an adjusting handle 17.

[0047] The number of movable seats 18 corresponds to the number of second threaded rods 16, and they are threadedly connected to the second threaded rods 16;

[0048] The number of clamping plates 19 corresponds to the number of movable seats 18, and the clamping plates 19 are connected to the movable seats 18. The clamping plates 19 are driven to move up and down in the vertical direction through threaded transmission to achieve pressing and limiting of the top of the rock wool board and prevent the rock wool board from shaking up and down during transportation.

[0049] The specific implementation process is as follows: one end of the second threaded rod 16 of the clamping assembly is rotatably connected to the trolley body 1 via a bearing, and the other end is welded to the adjusting handle 17; the movable seat 18 is threadedly connected to the second threaded rod 16 and slides in cooperation with the guide rail of the trolley body 1; the clamping plate 19 is welded to the top of the movable seat 18. Rotating the adjusting handle 17 drives the second threaded rod 16 to rotate, and the movable seat 18 rises and falls vertically, driving the clamping plate 19 to press down to the top of the rock wool board, limiting the vertical displacement of the rock wool board through friction; rotating the adjusting handle 17 in the opposite direction causes the clamping plate 19 to rise, releasing the rock wool board. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0050] Example 5:

[0051] This embodiment further defines the structure of the clamping plate 19 based on the above embodiments, such as... Figure 4 As shown, the clamping plate 19 consists of a fixed plate 20, a rotating plate 21, and a limiting member 22. One end of the fixed plate 20 is fixedly connected to the movable seat 18, and the rotating plate 21 is rotatably connected to the fixed plate 20 via a rotating shaft. The limiting member 22 is connected to the rotating plate 21. The rotating connection between the rotating plate 21 and the fixed plate 20 allows the clamping plate 19 to be folded or unfolded, reducing space obstruction when loading rock wool boards and improving operational convenience.

[0052] The specific implementation process is as follows: one end of the fixing plate 20 of the clamping plate 19 is welded to the movable seat 18, and the other end is rotatably connected to the rotating plate 21 via a rotating shaft; the limiting member 22 is installed on the rotating plate 21 to fix the rotation angle of the rotating plate 21. After releasing the locking of the limiting member 22, the rotating plate 21 can rotate around the rotating shaft to overlap with the fixing plate 20, reducing obstruction of the space above the trolley body 1 and facilitating the loading of rock wool boards; after loading, the rotating plate 21 is rotated back to the horizontal position and fixed by the limiting member 22, forming a complete clamping surface together with the fixing plate 20. Other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0053] Example 6:

[0054] This embodiment further defines the structure of the limiting member 22 based on the above embodiments, such as... Figure 4As shown, the limiting member 22 consists of a movable rod 23, an elastic member 24, and a limiting block 25. The movable rod 23 is slidably connected to the rotating plate 21 along its radial direction. The limiting block 25 is connected to one end of the movable rod 23 near the fixed plate 20, and a stop block is connected to the other end of the movable rod 23. The elastic member 24 is disposed between the stop block and the rotating plate 21, and is sleeved on the outside of the movable rod 23. Both ends of the elastic member 24 abut against the stop block and the rotating plate 21, respectively. The elastic force of the elastic member 24 drives the limiting block 25 to engage with the fixed plate 20, thereby fixing the angle of the rotating plate 21 and ensuring structural stability during clamping.

[0055] The specific implementation process is as follows: the movable rod 23 of the limiting member 22 slides radially through the through hole of the rotating plate 21, with a limiting block 25 welded to one end and a stop block welded to the other end; the elastic member 24, like a spring, is sleeved on the outside of the movable rod 23, with both ends abutting against the stop block and the rotating plate 21 respectively; the fixed plate 20 is provided with a positioning hole adapted to the limiting block 25. Pulling the stop block causes the movable rod 23 to compress the elastic member 24, and the limiting block 25 disengages from the positioning hole of the fixed plate 20, allowing the rotating plate 21 to rotate freely; releasing the stop block causes the elastic member 24 to reset and push the limiting block 25 into the positioning hole, fixing the angle of the rotating plate 21. Other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0056] Example 7:

[0057] This embodiment further defines the structure of the second threaded rod 16 based on the above embodiments, such as... Figure 2 As shown, a protective cover 26 is fitted over the outer side of the second threaded rod 16 for protection. The protective cover 26 isolates the second threaded rod 16 from the outside environment, preventing rock wool debris from adhering or being accidentally touched by operators, thus ensuring smooth thread transmission and operational safety.

[0058] The specific implementation process is as follows: the protective cover 26 is fitted onto the outside of the second threaded rod 16, with one end bolted to the trolley body 1 and the other end connected to the movable seat 18, extending and retracting synchronously with the movement of the movable seat 18. The protective cover 26 completely encloses the second threaded rod 16, preventing rock wool fibers from becoming entangled in the threads or dust from accumulating, while also preventing operators from touching the rotating threaded rod with their hands, thus reducing safety risks. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0059] Example 8:

[0060] This embodiment, based on the above embodiment, further adds omnidirectional wheels, such as... Figure 1 , Figure 2As shown, the bottom of the trolley body 1 is also equipped with omnidirectional wheels with brakes, and the rims of the omnidirectional wheels are covered with a rubber cushioning layer. The omnidirectional wheels with brakes enable the trolley to turn flexibly and stop at fixed points, while the rubber cushioning layer reduces vibration during transportation and protects the integrity of the rock wool board.

[0061] The specific implementation process is as follows: The bottom of the trolley body 1 is secured with four corner bolts to omnidirectional wheels with brakes, and the wheel rims are wrapped with a rubber buffer layer. Releasing the omnidirectional wheel brakes allows the trolley to turn 360° by pushing the pusher frame 3, adapting to narrow workshop aisles; when stopping, pressing the brake pedal locks the omnidirectional wheels to prevent the trolley from slipping; the rubber buffer layer absorbs vibrations on uneven ground, reducing displacement or damage to the rock wool boards caused by bumps. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0062] Example 9:

[0063] This embodiment, based on the above embodiment, further defines the structure of the push frame 3. The push frame 3 is fitted with a non-slip grip that can slide along its length. The outer surface of the non-slip grip has a wavy texture, and both ends of the non-slip grip have limiting protrusions. Through the sliding adjustment of the non-slip grip and the wavy texture, it adapts to the gripping habits of operators of different heights, enhances friction to prevent slippage, and improves pushing comfort.

[0064] The specific implementation process is as follows: a non-slip grip is fitted onto the push frame 3, with a wavy texture pressed onto its outer surface, and limit protrusions integrally formed at both ends. The operator can slide the non-slip grip along the length of the push frame 3 to a comfortable grip position. The wavy texture increases the friction between the hand and the grip, preventing slippage during pushing; the limit protrusions ensure that the grip does not detach from the push frame 3 when force is applied, improving operational stability. Other parts of this embodiment are the same as those in the above embodiment and will not be repeated.

[0065] It is understood that the working principle and working process of the rock wool transfer trolley structure according to one embodiment of the present utility model, such as the push frame 3 and the adjusting handle 17, are existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0066] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
