Description

Technical Field

[0001] This utility model relates to the technical field of roller furnace maintenance equipment, specifically to a multi-functional furnace roller replacement trolley. Background Technology

[0002] The furnace roller trolley is mainly used for gripping and replacing furnace rollers in roller conveyor furnaces. It can operate under temperature or even online conditions, and can quickly and efficiently complete the disassembly and installation of furnace rollers, greatly improving equipment maintenance capabilities.

[0003] During the disassembly of existing roller furnace rollers, the trolley needs to be driven to the roller to be replaced. First, the roller support bearing seat and heat insulation cylinder bolts are removed. Then, the roller gripping mechanism is fitted and fixed to the roller. In the existing gripping structure, the gripping part is generally a fixed structure and cannot be adjusted according to the size of the roller. In particular, the roller is in a high-temperature working state inside the equipment and will undergo thermal expansion. If there is a gap between the gripping structure and the end of the roller, the roller will not be able to be removed smoothly.

[0004] In addition, in the existing furnace roller trolleys, the drive structure mostly adopts a gear motor drive structure. In this structure, the positions of the gear and rack are fixed. Since the reciprocating operation of the gear and rack will cause wear, it will lead to a gap between the gear and rack, thus affecting the positioning accuracy of the entire trolley during operation. Utility Model Content

[0005] Based on the above description, this utility model provides a multi-functional furnace roller replacement trolley to solve the shortcomings of existing furnace roller trolleys, such as the inability to adjust the gripping structure according to actual use, the easy occurrence of gaps due to expansion at the furnace roller end affecting the gripping effect, and the easy occurrence of gaps due to wear in the gear and rack drive structure affecting the positioning accuracy of the entire trolley.

[0006] This utility model is achieved through the following technical solution:

[0007] A multifunctional furnace roller changing trolley includes a roller conveyor and a trolley body slidably mounted on the roller conveyor. The roller conveyor is provided with two sets of slide rails, which are arranged at intervals. The bottom of the trolley body is provided with two support seats, which are slidably mounted on the two sets of slide rails respectively. A drive assembly is also provided between the support seats and the slide rails to drive the trolley body to move horizontally. The top of the trolley body is also provided with a slide groove, on which a gripping assembly is movably mounted. One end of the gripping assembly extends outward and is clamped and fixed to the end of the furnace roller.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, each set of slide rails consists of two T-shaped rails arranged at intervals, and a mounting groove is provided between the two T-shaped rails, in which a rack is detachably and fixedly installed.

[0010] Furthermore, the drive assembly includes a groove disposed at the center of the bottom surface of the support base, a limit groove is vertically disposed on the inner side wall of the groove, and an installation plate is also disposed inside the groove. Connecting plates are formed by downward extension of the bottom sides of the installation plate, and a drive wheel is rotatably mounted between the two connecting plates.

[0011] Furthermore, a central shaft is provided at the center of the drive wheel, one end of which passes through the connecting plate and is provided with a worm gear. A drive motor is also provided on the mounting plate, and the output end of the drive motor extends downward to the bottom surface of the mounting plate and is connected to a worm. The worm gear meshes with the worm gear.

[0012] Furthermore, the top surface of the mounting plate is provided with four elastic support members on each of the four sides. The elastic support members are spring rods. The top end of the elastic support member is bolted to the bottom surface of the groove, and the bottom end of the elastic support member is bolted to the top surface of the mounting plate.

[0013] Furthermore, the gripping component includes a connecting seat slidably mounted on a slide groove, a gripping body fixedly mounted on the connecting seat, a positioning groove provided on one end face of the gripping body, a rectangular opening provided on the inner side wall of the positioning groove, and a gripper movably mounted inside the rectangular opening.

[0014] Furthermore, the gripping body is provided with an installation space inside, and a drive ring is rotatably installed inside. The drive ring is concentrically arranged with the positioning groove and has a spiral-shaped drive groove on its end face. The rectangular opening is connected to the installation space. The bottom end of the gripper has a protrusion that extends inward and is inserted into the drive groove. The gripping body is also provided with a servo motor. The back of the drive ring is provided with a transmission gear that meshes with the output end of the servo motor.

[0015] Furthermore, a lead screw is provided inside the slide groove, and a threaded hole is provided on the end face of the connecting seat extending into the slide groove. The lead screw is movably assembled with the connecting seat through the threaded hole. An adjustment motor is also provided inside the vehicle body, and the output end of the adjustment motor is connected to one end of the lead screw.

[0016] Furthermore, the support base is also equipped with an electric telescopic rod, and the top end of the electric telescopic rod is fixedly connected to the bottom surface of the vehicle body.

[0017] Furthermore, the vehicle body is also equipped with a console, which has a display and a control panel, and the console is remotely connected to the drive component and the grasping component respectively.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0019] 1. This application improves upon the existing furnace roller trolley by first changing the top clamping mechanism to an adjustable three-jaw clamping structure. This structure can be adjusted according to the expansion of the furnace roller under high temperature conditions, ensuring the clamping effect on the end of the furnace roller and avoiding the inability to remove the furnace roller smoothly due to the fit gap. Moreover, this structure can be used for the installation or disassembly of furnace rollers of various sizes, greatly improving the convenience of later maintenance.

[0020] 2. In this application, a combination of floating clamping structure and gear transmission structure is used. Compared with the existing drive structure, this application can use elastic support to allow the gear to continuously adjust during the wear process and always mesh tightly with the rack, thereby ensuring the positioning accuracy of the entire furnace roller trolley during operation and greatly improving the stability of the furnace roller trolley operation.

[0030] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0032] Combination Figure 1-8 As shown, a multi-functional furnace roller changing trolley includes:

[0033] Roller conveyor 1, a channel located on one side of the roller conveyor 1 furnace, has two sets of slide rails 11 arranged at intervals on its top surface;

[0034] The car body 2 has a rectangular top and two support seats 21 at the bottom. The two support seats 21 are slidably mounted on two sets of slide rails 11 to cooperate with the displacement of the car body 2.

[0035] The drive component 3 is located between the support base 21 and the slide rail 11. It is a gear motor drive structure, that is, it uses the meshing transmission of gears and racks as a power source to drive the vehicle body 2 to move along the slide rail 11.

[0036] The gripping component 4 is located on the top of the vehicle body 2 and is used to clamp the end of the furnace roller on the roller conveyor 1 to remove it, or to push a new furnace roller into the furnace of the roller conveyor 1 so that the staff can quickly disassemble and maintain it.

[0037] Specifically, in this embodiment, each set of slide rails 11 consists of two spaced-apart rails with a T-shaped cross-section. A mounting groove 12 is provided between the two T-shaped rails. A rack is fixedly installed in the mounting groove 12 with the toothed part facing upward.

[0038] The drive assembly 3 includes a groove 31 located at the bottom of the support base 21. The groove 31 is rectangular and has a limiting groove on its inner sidewall. Additionally, a mounting plate 32 is located inside the groove 31. The sidewalls of the mounting plate 32 extend to both sides and are movably fitted with the limiting groove. Therefore, the mounting plate 32 can move up and down inside the groove 31 along the limiting groove.

[0039] Two spaced connecting plates extend downward from the bottom surface of the mounting plate 32, and a drive wheel 33 is provided between the two connecting plates. The two ends of the central shaft of the drive wheel 33 are respectively rotatably inserted into the connecting plates, and one end extends to the outside of the connecting plate and is provided with a worm gear 36.

[0040] A drive motor 34 is also provided on the top of the mounting plate 32. The output end of the drive motor 34 extends vertically downward to the bottom of the mounting plate 32 and is connected to a worm gear 35. The worm gear 35 is engaged with the worm wheel 36, thereby driving the entire drive wheel 33 to rotate.

[0041] In addition, the drive motor 34 can also be directly mounted on the side wall of the connecting plate and its output end can be connected to the central shaft of the drive wheel 33 to drive the drive wheel 33 directly.

[0042] The surface of the drive wheel 33 is also surrounded by teeth, forming a circular gear structure, and these teeth mesh with the rack. Therefore, in this structure, simply starting the drive motor 34 can effectively utilize the gear and rack transmission method to drive the entire trolley to move along the slide rail 11.

[0043] However, in actual use, both gears and racks will experience some wear. To ensure the proper fit between them, an elastic support 37 should be vertically installed at each of the four corners of the top surface of the mounting plate 32. This elastic support 37 can be a damping spring, spring rod, cylinder, or other component with telescopic adjustment function. Its purpose is to apply a downward thrust to make the entire mounting plate 32 move downward, ensuring that the gear and rack mesh tightly. Even if there is a gap between them due to wear, the elastic thrust can quickly make up for the gap, thereby greatly improving the fit between them and making the positioning accuracy of the vehicle body 2 more accurate during travel.

[0044] Since the vehicle body 2 is relatively wide, the above drive components 3 should be provided in 4 sets, with each pair of two sets as a pair, and installed at both ends of the bottom surface of the support base 21 respectively. The 4 sets of drive components 3 should be synchronously driven and controlled.

[0045] The gripping component 4 includes a connecting seat 41 disposed on a slide groove 23 on the top surface of the vehicle body 2. A lead screw 24 is rotatably mounted inside the slide groove 23, and an adjusting motor is provided inside the vehicle body 2. The adjusting motor is connected to the lead screw 24 in a transmission manner. The connecting part extends into the slide groove 23 and is movably assembled with the lead screw 24 through a threaded hole, thereby facilitating the operator to control the adjusting motor to drive the gripping component 4 to move on the vehicle body 2.

[0046] The connecting seat 41 is provided with a gripping body 42. The end of the gripping body 42 facing the roller conveyor 1 furnace is provided with a positioning groove 43. The inner side wall of the positioning groove 43 is provided with a rectangular opening 44, and there are three rectangular openings 44 arranged in a circumferential array. A gripper 45 is slidably installed inside each rectangular opening 44. In addition, there is an installation space inside the gripping body 42. A drive ring 46 is rotatably installed inside the installation space. The drive ring 46 is concentrically arranged with the positioning groove 43, and a spiral groove is provided on the end face of the drive ring 46. The rectangular opening 44 is also connected to the installation space. The side wall of the gripper 45 is limited by a groove structure with the side wall of the rectangular opening 44, and its bottom extends inward into the installation space and fits into the groove. Therefore, when the drive ring 46 rotates, the arc-shaped inner wall of the groove can be used to force the gripper 45 to extend along the rectangular opening 44 towards the center, so that it can stick to the side wall of the furnace roller end and lock it in place. In this embodiment, the gripping body 42 is only drawn as a rectangular structure. In actual use, a pipe should be set on the positioning groove 43 to guide and transport the end of the furnace roller, or the appearance of the gripping body 42 can be set to other shapes, but the internal fixing structure remains unchanged.

[0047] A transmission gear is also provided on the back of the drive ring 46, and a servo motor 47 is correspondingly provided inside the gripping body 42. The output end of the servo motor 47 is provided with a gear sleeve that meshes with the transmission gear, thereby driving the drive ring 46 to rotate forward or in reverse.

[0048] In addition, the vehicle body 2 is also equipped with a clamping device for fixing the furnace rollers, such as hydraulic jacks and pressure roller blocks, which are used to further clamp the furnace rollers after they are grabbed to prevent them from shaking or falling off during transportation.

[0049] The support base 21 is also equipped with an electric telescopic rod 22, which is used to control the lifting and lowering of the entire car body 2 in order to adapt to the operation of the furnace roller at different positions and heights.

[0050] A control console 5 should also be installed on the top surface of the vehicle body 2 and on the side away from the roller conveyor furnace 1. The control console 5 is equipped with a display screen and a control panel, and is connected to the aforementioned servo motor 47, drive motor 34, adjustment motor and electric telescopic rod 22 via Bluetooth module or wire. The staff can directly adjust and control these components through the control console 5, further simplifying the maintenance steps of the roller conveyor furnace 1 and making the operation more convenient.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this utility model.
