Description

Technical Field

[0001] The utility model relates to the field of siliceous fireclay production equipment, in particular to a hoist with a limiting function. Background Art

[0002] Siliceous fireclay is a powder made of silica, waste silica bricks and refractory clay. Siliceous fireclay has a certain high temperature resistance and is not easily melted, softened or worn by high temperature. It can also resist chemical erosion and has important functions such as patching, covering, filling and sealing. It is widely used in various high-temperature furnaces, kilns and other industrial equipment. In the production process of siliceous fireclay, in order to efficiently transport the silicon fireclay to other processing equipment for processing, it is necessary to use a special equipment, that is, the silicon fireclay elevator.

[0003] As for the current elevators, storage barrels containing siliceous fire clay are usually placed on the lifting plate, and there is often a lack of special fixing devices for the storage barrels. During the rising process of the lifting plate, the storage barrels may accidentally fall, which may cause accidental injuries and deaths of workers and temporary interruption of the production process. In addition, the up and down movement of the lifting plate is usually only controlled by an electric screw. Since the lifting plate and the storage barrel are often heavy, and the friction between the electric screw and the lifting plate is small, the lifting plate may accidentally slide down during the rising process, thereby affecting the rising process of the lifting plate.

[0004] Therefore, those skilled in the art provide a hoist with a limiting function to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a hoist with a limiting function.

[0010] Through the above technical scheme, a control mechanism, a limiting mechanism and a fixing mechanism are provided in the hoist. The control mechanism controls the operation of the entire device through three electric screws. The limiting mechanism can provide a certain support to the support plate through the limiting plate, and can perform a double limiting effect on the support plate together with the vertical screw, thereby increasing the safety of the device.

[0011] Furthermore, the vertical plate is slidably arranged on the upper end of the base, and the middle position of the lower end of the vertical plate is threadedly sleeved on the upper screw rod;

[0012] Through the above technical solution, the base supports the vertical plate, and the vertical plate can slide horizontally along the upper end surface of the base as the upper screw rotates.

[0015] Furthermore, the lower ends of the two connecting plates are slidably arranged in the base, the middle position of the movable plate is threadedly sleeved on the lower screw rod, and the plurality of limit plates correspond to the positions of the plurality of limit holes;

[0016] Through the above technical solution, the rotation of the lower screw rod can drive the movement of the movable plate, and then drive the front and rear position adjustment of the limit plate.

[0017] Furthermore, the two sides of the rotating inclined plate are rotatably arranged in the support plate near the front end, and the storage barrel is movably arranged at the upper end of the rotating inclined plate;

[0018] Through the above technical solution, the two sides of the rotating inclined plate near the rear end are rotatably connected to the support plate, and the rotating inclined plate can ensure smooth loading and unloading of the storage barrel.

[0019] Furthermore, the position of the stabilizing block near the front end is threadedly sleeved on the vertical screw rod, and the position of the stabilizing block near the rear end is slidably sleeved on the stabilizing rod;

[0026] 1. The utility model proposes a hoist with a limiting function, in which a limiting mechanism is arranged. During use, a plurality of limiting plates in the limiting mechanism can support support plates of different heights. Contraction occurs only when the upper end of the telescopic block is subjected to pressure from the limiting plate, ensuring that the support plate can only move upward, so that the support plate has a double support and limiting structure, which can prevent the support plate from accidentally sliding down and improve the safety of the hoist, and can also reduce the pressure of the fixing mechanism on the vertical screw rod, ensuring the stable control of the electric screw rod on the fixing mechanism.

[0027] 2. The utility model proposes a hoist with a limiting function, in which a fixing mechanism is provided. During use, the threaded bolt in the fixing mechanism can move up and down by the supporting force and gravity, while driving the rotation of the fixing frame to complete the fixing of the storage barrel by the fixing frame. The rotating inclined plate can also flip up and down with the supporting force, which not only ensures the stable fixation of the storage barrel and prevents accidental falling off, thereby improving the safety of the hoist, but also can automatically adjust the fixing state of the storage barrel, facilitating the loading and unloading of the storage barrel.

[0037] The hoist is provided with a control mechanism 1, which controls the operation of the entire device through three electric screws.

The stabilizing rod 107 and the vertical screw 105 stabilize the stabilizing block 302 at the front and rear positions, which can prevent excessive pressure on the vertical screw 105. The limit hole 108 can be used for the limit plate 203 to pass through.

[0038] A limiting mechanism 2 is arranged near the rear end of the upper end of the control mechanism 1, and the limiting mechanism 2 includes two connecting plates 201, a plurality of limiting plates 203 are fixedly arranged at the front ends of the two connecting plates 201, a movable plate 202 is fixedly arranged at the lower ends of the two connecting plates 201 on the opposite side, the lower ends of the two connecting plates 201 are slidably arranged in the base 101, the middle position of the movable plate 202 is threadedly sleeved on the lower screw rod 103, and the plurality of limiting plates 203 correspond to the positions of the plurality of limiting holes 108;

[0039] The hoist is provided with a limiting mechanism 2, the main function of which is to support the lifted support plate 301 to prevent the support plate 301 from sliding down, the movable plate 202 can move forward and backward with the rotation of the lower screw rod 103, the movable plate 202 connects the two connecting plates 201, and can realize the synchronous movement of the two connecting plates 201, the two connecting plates 201 play a fixing role on the limiting plate 203, and multiple limiting plates 203 can support and limit the support plates 301 lifted to different heights;

[0040] A fixing mechanism 3 is provided at the front end of the control mechanism 1, and the fixing mechanism 3 includes a support plate 301, a rotating inclined plate 303, a storage barrel 306 and two threaded bolts 305. A stabilizing block 302 is fixedly provided at the rear end of the support plate 301, and telescopic blocks 309 are slidably provided near both sides of the rear end of the support plate 301. A fixing frame 304 is fixedly sleeved on the outer sides of the two threaded bolts 305 near the upper ends.

[0041] The two sides of the rotating inclined plate 303 are rotatably arranged in the support plate 301 near the front end, the storage barrel 306 is movably arranged at the upper end of the rotating inclined plate 303, the position of the stabilizing block 302 near the front end is threadedly sleeved on the vertical screw rod 105, and the position of the stabilizing block 302 near the rear end is slidably sleeved on the stabilizing rod 107. The front ends of the two telescopic blocks 309 are fixedly connected to the telescopic springs 308, and the front ends of the two telescopic springs 308 are fixedly connected to the support plate 301. The upper end of the rotating inclined plate 303 is provided with threaded grooves 307 near both sides, and the lower ends of the two threaded bolts 305 are respectively threadedly sleeved in the two threaded grooves 307;

[0042] The lifting machine is provided with a fixing mechanism 3, which is a structure for supporting and fixing the storage barrel 306. The support plate 301 can support the structure at the upper end. The stabilizing block 302 can move up and down with the rotation of the vertical screw rod 105, and can also drive the support plate 301 to move up and down together. The rotating inclined plate 303 can be turned up and down under the support of the lower platform. The fixing frame 304 rotates with the rotation of the threaded bolt 305. When the fixing frame 304 does not rotate, the two fixing frames 304 can fix the storage barrel 306 from both sides to prevent the storage barrel 306 from being tilted. In case the storage barrel 306 accidentally falls during the lifting process, a half-circle thread is arranged on the outside of the threaded bolt 305. The shorter thread can ensure that the threaded bolt 305 can move up and down smoothly when subjected to external force, and rotate at the same time to complete the state adjustment of the fixed frame 304. The storage barrel 306 is a high-temperature resistant barrel-shaped structure for storing siliceous fire clay. The threaded groove 307 is combined with the threaded bolt 305 to ensure the smooth rotation of the threaded bolt 305. The telescopic spring 308 can ensure the telescopic movement of the telescopic block 309. The rear end of the telescopic block 309 is inclined, and can move forward when subjected to upper end pressure.

[0043] Working principle: When the hoist is used, the hoist will transport the storage barrel 306 from the ground platform to the high platform. First, the upper screw rod 102 is used to control the vertical plate 104 to move forward until the lower end of the support plate 301 is in contact with the upper end of the low platform. Under the push of the low platform, the rotating inclined plate 303 is turned upward, and at the same time, the threaded bolt 305 is rotated while rising under the pressure, driving the two fixing frames 304 to rotate. At this time, the storage barrel 306 can be easily pushed onto the device along the inclined surface, and then the vertical plate 104 is controlled to move backward. After the pressure of the low platform is lost, the rotating inclined plate 303 is rotated downward until the upper end surface returns to a horizontal state. The two threaded bolts 305 also move downward under the neutral action, and the two fixing frames 304 rotate accordingly, and the storage barrel 306 is stably fixed on the rotating inclined plate 303.

[0044] Then, the movable plate 202 is controlled to move forward by the lower screw rod 103 until the limit plate 203 passes through the corresponding limit hole 108 and the front end of the connecting plate 201 is in contact with the rear end of the vertical plate 104, and then the vertical screw rod 105 is started, and the stabilizing block 302 moves upward with the support plate 301 as the vertical screw rod 105 rotates. When the telescopic block 309 contacts the limit plate 203 and continues to rise, the telescopic block 309 shrinks toward the inside of the support plate 301 under the pressure of the limit plate 203. After block 309 passes through the limit plate 203, the telescopic block 309 returns to its original position under the action of the telescopic spring 308, and then repeatedly passes through multiple limit plates 203 to reach the specified height, and then the limit plate 203 and the vertical plate 104 are controlled to move forward together, and the lower end of the support plate 301 is fitted with the upper end of the high platform, and the previous process is repeated. The fixed frame 304 rotates, and the upper end surface of the rotating inclined plate 303 is tilted. The storage barrel 306 can be easily moved along the inclined surface to the high platform to complete the transportation of siliceous fire mud.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
