Description

Technical Field

[0001] This utility model relates to the field of roller changing trolley technology, specifically a roller changing trolley with a detachable anti-fall safety plate. Background Technology

[0002] Roll changing trolleys are specialized automated or semi-automated handling tools used in industrial production for transporting and replacing various roller-shaped equipment, such as rolling mill rolls, papermaking rolls, and printing rolls. They primarily address the problems of heavy rollers, frequent replacements, and the difficulty and high risk of manual operation. They are widely used in industries such as metallurgy, papermaking, printing, metal processing, and textiles, where frequent replacement of roller components is required. Roll changing trolleys use specialized brackets, clamps, or slots to stably support rollers, especially heavy-duty rollers, preventing them from shaking or falling during transport.

[0003] In the prior art, such as the roller changing trolley device disclosed in CN218367872U, there is an overall roller changing device structure. This structure includes a bottom moving frame, a top lifting screw, a lifting rod drive shaft, a rubber roller top moving trolley, and a rubber roller assembly. The rubber roller assembly is placed on the upper surface of the rubber roller top moving trolley, which rests on the top surface of the top lifting screw. Two top lifting screws are provided, symmetrically arranged on both sides of the bottom moving frame. The device is supported by the top lifting screw via the rubber roller top moving trolley. The height of the top lifting screw is controlled by the lifting rod drive shaft. During loading, the top lifting screw is lowered to facilitate the placement of the rubber roller assembly. When loading the rubber roller assembly, the top lifting screw is raised to elevate the rubber roller top moving trolley to be flush with the machine. The entire loading process reduces manual handling and prevents the rubber roller assembly from being bumped or damaged.

[0004] The existing trolley reduces manual handling during the loading process and avoids collisions with the rubber roller assembly. However, it is inconvenient to place rollers of different lengths during use, and different trolleys are required to replace rollers of different lengths, making it less practical. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problems of inconvenience in placing rollers of different lengths during use, and the need to change different carriages when changing rollers of different lengths, resulting in poor practicality.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A trolley for changing rollers of a detachable anti-slip safety plate includes a trolley base, wheels, hydraulic cylinders, and a support plate. The wheels are fixed to the lower surface of the trolley base with bolts, the hydraulic cylinders are fixed to both ends of the trolley base with screws, and the support plate is fixed to the telescopic end of the hydraulic cylinder. The trolley also includes:

[0009] The system includes a movable plate, a mounting tube, and a stepper motor. The movable plate is located at the upper end of the trolley base, the mounting tube is located on one side of the movable plate, and the stepper motor is located on the side wall of the trolley base.

[0010] As a further improvement of this utility model: an installation plate is fixedly connected to the upper surface of the movable plate, and two sliding grooves are formed on the upper surface of the installation plate.

[0011] As a further improvement of this utility model: both of the sliding grooves are slidably connected with locking blocks inside, and a connecting plate is integrally fixed on the upper surface of the locking blocks.

[0012] As a further improvement of this utility model: a placement component is fixed to the upper end of the connecting plate, and a limiting component is installed on the upper surface of the placement component.

[0013] As a further improvement of this utility model, both ends of the limiting member are equipped with fixing bolts that are threadedly connected to the placement member.

[0014] As a further improvement of this utility model: the internal telescopic connection of the mounting tube has a limiting rod, and one end of the limiting rod is fixed with a pull plate.

[0015] As a further embodiment of this utility model: a connecting member is fixed to one side of the limiting rod, a compression spring is sleeved on the limiting rod, the compression spring abuts against the side wall of the connecting member and the pull plate, a limiting hole is opened on the locking block, and the end of the limiting rod away from the pull plate is inserted into the limiting hole.

[0016] As a further embodiment of this utility model: the power output shaft of the stepper motor is fixed with a lead screw, the lead screw is threadedly connected to the movable plate, a guide groove is provided on the trolley base, and the lower part of the movable plate is slidably connected in the guide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model allows for manual pulling of the pull plate on the mounting tube, which drives the limit rod to move. When the limit rod moves, it causes the connecting piece to compress the clamping spring, releasing the fixing of the locking block. Through the sliding groove opened on the mounting plate, the placement piece can be pulled horizontally, thereby adjusting the distance between the two placement pieces. This facilitates the use of rolls of different lengths and allows for the disassembly of the connecting plate and the placement piece, improving practicality.

[0019] 2. This utility model uses a stepper motor to drive the lead screw to rotate. With the cooperation of the guide groove, the rotation of the lead screw drives the threaded movable plate to move horizontally. When the movable plate moves, it drives the connecting plate, so that the rolls on the two placement parts move into the roll mill, thereby facilitating the replacement of the rolls.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Please see Figures 1-5 This embodiment provides a trolley for changing rollers of a detachable anti-slip safety plate, including a trolley base 1, wheels 2, hydraulic cylinders 3, and support plates 4. The wheels 2 are fixed to the lower surface of the trolley base 1 by bolts, the hydraulic cylinders 3 are fixed to both ends of the trolley base 1 by screws, and the support plates 4 are fixed to the telescopic ends of the hydraulic cylinders 3.

[0030] The roller changing trolley of the detachable anti-fall safety plate also includes a movable plate 5, an mounting tube 6 and a stepper motor 7. The movable plate 5 is located at the upper end of the trolley base 1, the mounting tube 6 is located on one side of the movable plate 5, and the stepper motor 7 is located on the side wall of the trolley base 1.

[0031] Specifically, an installation plate 51 is fixedly connected to the upper surface of the movable plate 5. The installation plate 51 is fixed to the upper surface of the movable plate 5, and two grooves 52 are formed on the upper surface of the installation plate 51.

[0032] Furthermore, the groove 52 on the mounting plate 51 allows the placement piece 55 to be pulled horizontally, thereby adjusting the distance between the two placement pieces 55 and facilitating the use of rolls of different lengths.

[0033] Specifically, both slides 52 are slidably connected with a locking block 53. A connecting plate 54 is integrally fixed on the upper surface of the locking block 53. A placement part 55 is fixed on the upper end of the connecting plate 54. A limiting part 56 is installed on the upper surface of the placement part 55. Both ends of the limiting part 56 are fitted with fixing bolts 57 that are threadedly connected to the placement part 55.

[0034] Furthermore, the trolley base 1 is moved to a suitable position by the wheels 2, and then the roller to be replaced is placed on the two placement pieces 55 by the hoisting equipment, thereby placing the roller.

[0035] In use, the trolley base 1 is first moved to a suitable position using the wheels 2. Then, the roller to be replaced is placed on the two placement pieces 55 using a hoisting device. The roller is then placed, and the limiting piece 56 is placed on the placement piece 55. The fixing bolts 57 are then tightened to limit the two ends of the roller, facilitating subsequent replacement. The trolley is then moved using the wheels 2. The hydraulic cylinder 3 drives the support plate 4 to move vertically, so that the lower surface of the support plate 4 contacts the ground. The support plate 4 is then driven, causing the cylinder body of the hydraulic cylinder 3 to move the trolley base 1, separating the wheels 2 from the ground. This effectively reduces the possibility of the trolley base 1 moving unexpectedly. The placement piece 55 can be pulled horizontally using the groove 52 on the mounting plate 51, thereby adjusting the distance between the two placement pieces 55. This facilitates the use of rollers of different lengths and allows for the disassembly of the connecting plate 54 and the placement piece 55, improving practicality.

[0036] The internal telescopic connection of the mounting tube 6 is a limiting rod 61, and one end of the limiting rod 61 is fixed with a pull plate 62.

[0037] Furthermore, a connector 63 is fixed to one side of the limiting rod 61, and a compression spring 64 is sleeved on the limiting rod 61. The compression spring 64 abuts against the side wall of the connector 63 and the pull plate 62. A limiting hole 65 is opened on the locking block 53, and the end of the limiting rod 61 away from the pull plate 62 is inserted into the limiting hole 65.

[0038] In this embodiment, by pulling the pull plate 62 on the mounting tube 6, the limiting rod 61 is driven to move, and the limiting rod 61 separates from the limiting hole 65 on the locking block 53.

[0039] Furthermore, when the limit rod 61 moves, it will cause the connecting piece 63 to compress the clamping spring 64, thereby releasing the fixation of the locking block 53.

[0040] In summary, when using the detachable anti-slip safety plate roll changing trolley, manually pull the pull plate 62 on the mounting tube 6 to move the limit rod 61. When the limit rod 61 moves, it will cause the connecting piece 63 to compress the clamping spring 64, releasing the fixation of the locking block 53. Through the sliding groove 52 opened on the mounting plate 51, the placement piece 55 can be pulled horizontally, thereby adjusting the distance between the two placement pieces 55, which is convenient for using rolls of different lengths. Furthermore, the connecting plate 54 and the placement piece 55 can be disassembled, improving practicality.

[0041] Specifically, the power output shaft of the stepper motor 7 is fixed with a lead screw 71, which is threadedly connected to the movable plate 5. A guide groove 72 is provided on the trolley base 1, and the lower part of the movable plate 5 is slidably connected in the guide groove 72.

[0042] Furthermore, the stepper motor 7 drives the lead screw 71 to rotate. With the cooperation of the guide groove 72, the rotation of the lead screw 71 drives the threaded movable plate 5 to move horizontally. When the movable plate 5 moves, it drives the connecting plate 54, so that the rolls on the two placement parts 55 move into the rolling mill.

[0043] In use, the stepper motor 7 drives the lead screw 71 to rotate. With the cooperation of the guide groove 72, the rotation of the lead screw 71 drives the threaded movable plate 5 to move horizontally. When the movable plate 5 moves, it drives the connecting plate 54, so that the rolls on the two placement parts 55 move into the rolling mill, which facilitates the replacement of the rolls. When rolls of different lengths are needed, the pull plate 62 on the mounting tube 6 can be pulled manually, which drives the limit rod 61 to move. At this time, the limit rod 61 separates from the limit hole 65 on the clamping block 53. When the limit rod 61 moves, it drives the connecting part 63 to compress the clamping spring 64, releasing the fixation of the clamping block 53.

[0044] In summary, when using the detachable anti-slip safety plate's roller changing trolley, manually pulling the pull plate 62 on the mounting tube 6 moves the limit rod 61. When the limit rod 61 moves, it causes the connecting piece 63 to compress the clamping spring 64, releasing the fixation of the locking block 53. Through the sliding groove 52 on the mounting plate 51, the placement piece 55 can be pulled horizontally, thereby adjusting the distance between the two placement pieces 55, facilitating the use of rollers of different lengths. It also allows for the disassembly of the connecting plate 54 and the placement piece 55. Furthermore, the stepper motor 7 drives the lead screw 71 to rotate. With the cooperation of the guide groove 72, the rotation of the lead screw 71 causes the threaded movable plate 5 to move horizontally. When the movable plate 5 moves, it drives the connecting plate 54, causing the rollers on the two placement pieces 55 to move into the rolling mill, thus facilitating the replacement of the rollers.
