Description

Technical Field

[0001] This utility model relates to the field of trolleys for handling and installation, and in particular to a trolley for handling and installing water-cooled screens. Background Technology

[0002] The water-cooled screen handling and installation trolley consists of a fixed frame, an adjustable track, a hydraulic device, a moving frame, and a limiting device. It is mainly used for handling and installing water-cooled screens used in single crystal furnaces and is quite common in the existing technology.

[0003] Existing technologies, such as the utility model patent with announcement number CN223304587U, disclose an auxiliary installation bracket for a single-crystal furnace water-cooled screen. This patent uses a handle plate, one side of which is fixedly connected to a clamping plate. Auxiliary frames are set on both sides of the clamping plate, and a positioning base plate is set at the bottom of the auxiliary frames. A rubber clamping block is installed on the upper side of the positioning base plate, and a soft-headed push rod is set on the upper side of the rubber clamping block. A connecting rod is installed on the upper side of the soft-headed push rod, and a pressure plate is set at one end of the connecting rod. A threaded rod is slidably sleeved in the pressure plate, and a threaded sleeve is sleeved on the threaded rod. The beneficial effect is that the water-cooled screen is initially limited and fixed by the rubber clamping block. Then, by twisting the threaded sleeve, the threaded sleeve moves downward, thereby indirectly causing the connecting rod to drive the soft-headed push rod to abut against the inner ring surface of the water-cooled screen through the pressure plate until one end of the soft-headed push rod abuts against the inner wall of the water-cooled screen, thereby fixing the water-cooled screen again. Finally, through the fixed connection between the clamping plates, the water-cooled screen can be lifted by pulling the handle plate, making it easy for the operator to accurately place the water-cooled screen into the corresponding position.

[0004] In the existing technology, when using the trolley for transporting and installing water-cooled screens inside a single crystal furnace, the water-cooled screen is prone to shaking inside the trolley because the existing trolley does not have a device to prevent the water-cooled screen from shaking. In severe cases, the water-cooled screen may collide with the inner wall of the trolley, causing damage to the water-cooled screen. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, when using a trolley for transporting and installing water-cooled screens inside a single crystal furnace, the water-cooled screen is prone to shaking inside the trolley because the existing trolley does not have a device to prevent the water-cooled screen from shaking. In severe cases, the water-cooled screen may collide with the inner wall of the trolley, causing damage to the water-cooled screen. Therefore, this utility model proposes a trolley for transporting and installing water-cooled screens.

[0006] To solve the above technical problems, this utility model provides a trolley for transporting and installing water-cooled screens, including: a fixed frame and a replacement structure. A hydraulic device is installed on the inner wall of the fixed frame. A movable frame is installed on the upper surface of the fixed frame. Two adjusting rails are installed on the upper surface of the movable frame. Limiting devices are installed on the upper surfaces of the adjusting rails. A limiting structure is provided inside the fixed frame. The limiting structure includes two fixed rods and two positioning rods. The two fixed rods are fixedly connected to the fixed frame. The two positioning rods are fixedly connected to the fixed frame. A rotating plate is rotatably connected to the arc surface of the fixed rod. Two coil springs are sleeved on the arc surface of the fixed rod. The two ends of the coil springs are fixedly connected to the rotating plate and the fixed rod, respectively. Mounting blocks are fixedly connected to the sides of the two rotating plates that are close to each other. Each of the two positioning rods has a fixed limiting plate on its closest side. Protective pads are installed on the sides of the two limiting plates that are close to each other using a replacement structure. A fixing plate is fixedly connected to the arc surfaces of the two positioning rods. Two adjusting plates are slidably connected to the arc surfaces of the two positioning rods. An adjusting frame is fixedly connected to the upper surface of each adjusting plate. Rollers are slidably connected to the inner wall of the adjusting frame, and the rollers abut against the rotating plate. A connecting frame is fixedly connected to the side of the adjusting plate away from the hydraulic device. A connecting plate is rotatably connected to the inner wall of the connecting frame. A lead screw is rotatably connected to the side of the fixing plate away from the hydraulic device. A moving plate is threadedly connected to the arc surface of the lead screw. The moving plate is rotatably connected to the two connecting plates. A turntable is fixedly connected to the end of the lead screw away from the fixing plate. A rotating rod is fixedly connected to the side of the turntable away from the fixing plate.

[0007] The effect achieved by the above components is that when personnel need to use the transport and installation trolley to move the water-cooled screen, they can rotate the rotating rod to move the two protective pads closer to the water-cooled screen until the two protective pads come into contact with the water-cooled screen. This can prevent the water-cooled screen from shaking during the movement of the water-cooled screen, thereby improving the stability of the water-cooled screen during the movement.

[0008] Preferably, the inner wall of the movable plate is slidably connected to two limiting rods, and the two limiting rods are fixedly connected to the fixed plate.

[0009] The effect achieved by the above components is that the limiting rod can limit the movement of the moving plate, thereby improving the stability of the moving plate during its movement.

[0010] Preferably, the arc surface of the rotating rod is fixedly connected to an anti-slip sleeve, and the cross-section of the anti-slip sleeve is a hollow circle.

[0011] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the operator's hand and the rotating rod, and can prevent the operator from slipping during the rotation of the rotating rod.

[0012] Preferably, the rotating plate is made of stainless steel.

[0013] The effect achieved by the above components is that the stainless steel plate has high strength and good wear resistance, which can prevent the plate from deforming during short-term use.

[0014] Preferably, the upper surface of the mounting block is provided with a replacement structure, the replacement structure including a mounting frame and two limiting grooves. The mounting frame is fixedly connected to the mounting block, and both limiting grooves are formed on limiting plates. A connecting plate is slidably connected to the inner wall of the limiting grooves. The two connecting plates are fixedly connected to a protective pad. A baffle is slidably connected to the inner wall of the mounting frame, and a threaded rod is threadedly connected to the inner wall of the mounting frame. The threaded rod is movably connected to the baffle.

[0015] The effect achieved by the above components is as follows: when the protective pad has been used for a long time and its surface is severely worn and needs to be replaced, the personnel can rotate the threaded rod to make it slide out of the inner wall of the baffle. Then the personnel can move the baffle until it is away from the upper surface of the protective pad. Then the personnel can move the protective pad until the connecting plate slides out of the inner wall of the limiting groove. This allows the personnel to quickly replace the protective pad and improves the replacement efficiency.

[0016] Preferably, a magnetic block is fixedly connected to the inner wall of the mounting bracket, and an iron block is fixedly connected to the inner wall of the baffle.

[0017] The effect achieved by the above components is that the magnetic block and the iron block can limit the position of the baffle, preventing the baffle from moving on its own when the protective pad is replaced, thereby improving the ease of operation for personnel.

[0018] Preferably, an auxiliary plate is fixedly connected to the side of the baffle away from the protective pad, and the cross-section of the auxiliary plate is rectangular.

[0019] The effect achieved by the above components is that the auxiliary plate makes it easier for personnel to move the baffle, thereby improving the ease of operation for personnel.

[0020] Compared with related technologies, the water-cooled screen handling and installation trolley provided by this utility model has the following advantages: This utility model provides a trolley for transporting and installing water-cooled screens. By setting a limiting structure, when personnel need to use the trolley to move the water-cooled screen, the limiting structure can limit the water-cooled screen, which can prevent the water-cooled screen from shaking during the movement process, thereby improving the stability of the water-cooled screen during the movement process.

[0021] By setting up a replacement structure, when the protective pad has undergone long-term use and its surface shows severe wear and needs to be replaced, the replacement structure can facilitate the replacement of the protective pad by personnel, thereby speeding up the replacement process and improving personnel replacement efficiency.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figure 1 The present invention provides a trolley for transporting and installing a water-cooled screen, comprising: a fixed frame 1 and a replacement structure 4. A hydraulic device 5 is installed on the inner wall of the fixed frame 1. A movable frame 6 is installed on the upper surface of the fixed frame 1. Two adjusting rails 2 are installed on the upper surface of the movable frame 6. A limiting device 7 is installed on the upper surface of the adjusting rails 2. A limiting structure 3 is provided inside the fixed frame 1. A replacement structure 4 is provided on the upper surface of the mounting block 310.

[0027] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The limiting structure 3 includes two fixed rods 303 and two positioning rods 301. The two fixed rods 303 are fixedly connected to the fixed frame 1, and the two positioning rods 301 are fixedly connected to the fixed frame 1. A rotating plate 304 is rotatably connected to the arc surface of the fixed rods 303. Two coil springs 318 are sleeved on the arc surface of the fixed rods 303. The two ends of the coil springs 318 are fixedly connected to the rotating plate 304 and the fixed rods 303, respectively. Mounting blocks 310 are fixedly connected to the sides of the two rotating plates 304 that are close to each other. Limiting plates 311 are fixedly connected to the sides of the two mounting blocks 310 that are close to each other. Protective pads 312 are installed on the sides of the two limiting plates 311 that are close to each other by means of a replacement structure 4. A fixing plate 302 is fixedly connected to the arc surface of the two positioning rods 301. Two adjusting plates 305 are slidably connected to the arc surface of 301. An adjusting frame 306 is fixedly connected to the upper surface of the adjusting plate 305. A roller 307 is slidably connected to the inner wall of the adjusting frame 306. The roller 307 abuts against the rotating plate 304. A connecting frame 308 is fixedly connected to the side of the adjusting plate 305 away from the hydraulic device 5. A connecting plate 309 is rotatably connected to the inner wall of the connecting frame 308. A lead screw 319 is rotatably connected to the side of the fixed plate 302 away from the hydraulic device 5. A moving plate 314 is threadedly connected to the arc surface of the lead screw 319. The moving plate 314 is rotatably connected to the two connecting plates 309. A turntable 315 is fixedly connected to the end of the lead screw 319 away from the fixed plate 302. A rotating rod 316 is fixedly connected to the side of the turntable 315 away from the fixed plate 302. When personnel need to move the water-cooled screen using a transport and installation trolley, they can rotate the rotating rod 316 to move the two protective pads 312 closer to the water-cooled screen until they abut against it. This prevents the water-cooled screen from shaking during movement, thus improving its stability. Two limiting rods 313 are slidably connected to the inner wall of the moving plate 314, and these limiting rods 313 are fixedly connected to the fixed plate 302. The limiting rods 313 limit the movement of the moving plate 314, improving its stability during movement. An anti-slip sleeve 317 is fixedly connected to the arc surface of the rotating rod 316. The anti-slip sleeve 317 has a hollow circular cross-section. The anti-slip sleeve 317 increases the friction between the personnel's hands and the rotating rod 316, preventing slippage during rotation. The rotating plate 304 is made of stainless steel. Stainless steel plates have high strength and good wear resistance, which can prevent deformation of 304 plates during short-term use. In the embodiments of this utility model, please refer to Figure 4The replacement structure 4 includes a mounting bracket 41 and two limiting grooves 47. The mounting bracket 41 is fixedly connected to the mounting block 310. Both limiting grooves 47 are opened on the limiting plate 311. The inner wall of the limiting groove 47 is slidably connected to a connecting plate 48. The two connecting plates 48 are fixedly connected to a protective pad 312. The inner wall of the mounting bracket 41 is slidably connected to a baffle 42. The inner wall of the mounting bracket 41 is threadedly connected to a threaded rod 46. The threaded rod 46 is movably connected to the baffle 42. When the protective pad 312 shows severe wear after prolonged use and needs replacement, personnel can rotate the threaded rod 46 to slide it out of the inner wall of the baffle 42. Then, personnel can move the baffle 42 until it is away from the upper surface of the protective pad 312, and then move the protective pad 312 again until the connecting plate 48 is completely slid out of the inner wall of the limiting groove 47. This allows for convenient and quick replacement of the protective pad 312, improving replacement efficiency. A magnetic block 45 is fixedly connected to the inner wall of the mounting bracket 41, and an iron block 44 is fixedly connected to the inner wall of the baffle 42. The magnetic block 45 and the iron block 44 limit the movement of the baffle 42, preventing it from moving on its own during replacement, thus improving ease of operation. An auxiliary plate 43 with a rectangular cross-section is fixedly connected to the side of the baffle 42 away from the protective pad 312. The auxiliary plate 43 allows personnel to easily move the baffle 42, which can improve the ease of operation for personnel; The working principle of the water-cooled screen handling and installation trolley provided by this utility model is as follows: When personnel need to use the handling and installation trolley to move the water-cooled screen, the personnel first move the water-cooled screen so that the two fixed arms of the water-cooled screen are placed inside the limiting device 7. Then, the personnel use the anti-slip sleeve 317 to drive the rotating rod 316 to rotate. The anti-slip sleeve 317 can increase the friction between the personnel's hands and the rotating rod 316, which can prevent the personnel from slipping during the rotation of the rotating rod 316. Then, the rotating rod 316 drives the turntable 315 to rotate, and the turntable 315 drives the lead screw 319 to rotate. The movable plate 314 is moved closer to the fixed plate 302, and slides on the arc surface of the two limiting rods 313. The limiting rods 313 can limit the movable plate 314, which can improve the stability of the movable plate 314 during movement. Then, the movable plate 314 also moves one end of the two connecting plates 309 closer to the fixed plate 302. The connecting plates 309 move the connecting frame 308 away from the fixed plate 302. The connecting frame 308 moves the adjusting plate 305 away from the fixed plate 302. The adjusting plate 305 is positioned on the arc surface of the two positioning rods 302. The slidable surface of plate 1 slides, and the adjusting plate 305 also drives the adjusting frame 306 to move away from the fixed plate 302. Then, the adjusting frame 306 drives the roller 307 to move away from the fixed plate 302. The roller 307 drives the rotating plate 304 to rotate. The rotating plate 304 drives the two coil springs 318 to rewind. The rotating plate 304 also drives the mounting block 310 to rotate towards the water-cooled screen. The mounting block 310 drives the limiting plate 311 to move towards the water-cooled screen. The limiting plate 311, with the help of the replacement structure 4, drives the protective pad 312 to rotate towards the water-cooled screen until the two protective pads rotate towards the water-cooled screen. The pad 312 abuts against the water-cooled screen. The rotating plate 304 is made of stainless steel, which has high strength and good wear resistance, preventing deformation of the rotating plate 304 during short-term use. Then, the personnel move the transport and installation trolley to move the water-cooled screen to the appropriate position. Then, the personnel press the hydraulic device 5 to move the water-cooled screen upward. When the water-cooled screen is moved to the appropriate height, the personnel rotate the water-cooled screen. At this time, the limiting device 7 slides inside the adjusting track 2 until the water-cooled screen is rotated to the appropriate installation angle, making it convenient for the personnel to install the water-cooled screen inside the single crystal furnace.

[0028] In addition, when the protective pad 312 shows severe wear after prolonged use and needs to be replaced, the operator can first rotate the threaded rod 46 away from the baffle 42 until the threaded rod 46 completely slides out of the inner wall of the baffle 42. Then, the operator can use the auxiliary plate 43 to move the baffle 42 away from the mounting bracket 41. The auxiliary plate 43 facilitates the movement of the baffle 42, improving the operator's ease of operation. Then, the baffle 42 moves the iron block 44 towards the magnetic block 45 until the magnetic block 45 and the iron block 44 are attracted to each other. The magnetic block 45 and the iron block 44 can limit the movement of the baffle 42, preventing it from moving on its own when the operator replaces the protective pad 312, thus improving the operator's ease of operation. Then, the operator moves the protective pad 312, which moves the two connecting plates 48 upward until the connecting plates 48 completely slide out of the inner wall of the limiting groove 47.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
