Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a safety protection device for hydraulic cylinders. Background Technology

[0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a speed reduction device and has no transmission backlash, resulting in smooth movement. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] The existing hydraulic cylinders do not have a good protective structure, which makes them easy to be scratched and worn by flying gravel on construction sites, thus affecting the normal operation and service life of the hydraulic cylinders.

[0004] An existing patent (publication number: CN213298462U) discloses a safety protection device for a hydraulic cylinder. The secondary protective cover and the main protective housing are tightly fitted together as one unit. After the main protective housing has completely wrapped the hydraulic cylinder, the heat generated around the outside of the hydraulic cylinder can be conducted to the heat dissipation fins through the setting of heat-conducting pads. Then, the heat dissipation fins dissipate the heat to achieve the purpose of heat dissipation and cooling, thereby maintaining a stable temperature inside the main protective housing.

[0005] Existing patents offer solutions to the aforementioned problems, but their cooling effects are unsatisfactory. In actual use, they rely solely on passive heat dissipation. While the heat dissipation efficiency is significantly reduced under high ambient temperatures or high load conditions, the lack of a cooling structure prevents real-time adjustment of the heat dissipation intensity based on oil temperature. Delayed manual intervention often leads to untimely heat dissipation, causing sudden malfunctions and impacting production efficiency, thus reducing the practicality of the device.

[0006] Therefore, a safety protection device for hydraulic cylinders is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a safety protection device for hydraulic cylinders, which can solve the problems of poor cooling effect of existing hydraulic cylinder safety protection devices. In actual use, they rely solely on passive heat dissipation. Under high ambient temperature or high load conditions, the heat dissipation efficiency is significant, but due to the lack of a cooling structure, the heat dissipation intensity cannot be adjusted in real time according to the oil temperature. Often, the delayed manual intervention leads to untimely heat dissipation, causing sudden failures, which in turn affects production and processing efficiency and reduces the practicality of the device.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic cylinder safety protection device, comprising a hydraulic cylinder body, a protective component fixedly connected to the surface of the hydraulic cylinder body, and a wind-cooled dust-collecting component provided on the surface of the protective component, the protective component comprising a protective shell, a fixed ring movably connected to the top of the protective shell, and a plurality of heat dissipation plates fixedly connected to the surface of the protective shell.

[0009] The air-cooled dust collection assembly includes two annular dust collection plates. A dust collection pipe is fixedly connected to the right side of each of the two annular dust collection plates, and the two annular dust collection plates are located at the top and bottom of the protective shell surface, respectively.

Slider blocks are movably connected to both sides of the inner wall of the storage box, and a storage compartment is fixedly connected between the opposite sides of the two sliders.

[0010] Preferably, a fixing block is fixedly connected to both the front and rear sides of the bottom of the fixing ring, and a movable plate is movably connected inside the fixing block. A spring is fixedly connected to one side of each of the two movable plates opposite to the spring, and a pressing block is fixedly connected to the side of the movable plate away from the spring.

[0011] Preferably, the top of the front and rear sides of the inner wall of the protective shell is provided with positioning grooves for use with fixing blocks, and the surface of the fixing block is in contact with the inner wall of the positioning groove.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A hydraulic cylinder safety protection device includes a hydraulic cylinder body 1, a protective component 2 fixedly connected to the surface of the hydraulic cylinder body 1, and a wind-cooled dust-collecting component 3 provided on the surface of the protective component 2. The protective component 2 includes a protective shell 201, a fixed ring 202 movably connected to the top of the protective shell 201, and a plurality of heat dissipation plates 203 fixedly connected to the surface of the protective shell 201.

[0029] The air-cooled dust collection assembly 3 includes two annular dust collection plates 301. Dust collection pipes 302 are fixedly connected to the right side of each of the two annular dust collection plates 301. The two annular dust collection plates 301 are located at the top and bottom of the protective shell 201, respectively. The other end of the dust collection pipe 302 is fixedly connected to a main dust collection pipe 303. A connecting hose 304 is fixedly connected to the right side of the main dust collection pipe 303. A fan 305 is fixedly connected to the other end of the connecting hose 304. A storage box 306 is fixedly connected to the side of the fan 305 away from the connecting hose 304. Slider blocks 307 are movably connected to both sides of the inner wall of the storage box 306. A storage box 308 is fixedly connected between the opposite sides of the two sliders 307.

[0030] In this embodiment: by pressing the pressing block 207, the moving plate 205 is moved smoothly and the spring 206 is compressed, releasing the fixation of the protective component 2, so that the protective shell 201 can be smoothly fitted onto the surface of the hydraulic cylinder body 1. At the same time, under the action of the spring 206, the pressing block 207 is driven to smoothly reset, so that it is accurately embedded in the protective shell 201, completing the quick installation of the protective component 2. With the help of the heat dissipation plate 203, the heat generated by the hydraulic cylinder body 1 can be dissipated in time, ensuring its stable operation and improving the ease of use of the protective component 2. Then, under the action of the fan 305, it generates suction, which is then passed through... The connecting hose 304, the main suction pipe 303, and the suction pipe 302 transmit the dust to the annular suction plate 301. The annular suction plate 301 forms an annular negative pressure zone, which drives the surrounding air and dust to flow. This not only allows the dust generated during the processing to flow into the storage box 306 through the annular suction plate 301, but also accelerates the airflow at the heat dissipation plate 203, achieving the dual functions of dust removal and heat dissipation, thus improving the practicality of the device. Furthermore, through the cooperation of the slider 307 and the storage box 308, the dust in the storage box 306 can be stored, and the slider 307 can also restrict the movement of the storage box 308, making it convenient to clean the dust.

[0031] Specifically, such as Figure 5As shown, a fixing block 204 is fixedly connected to the front and rear sides of the bottom of the fixing ring 202, and a movable plate 205 is movably connected inside the fixing block 204. A spring 206 is fixedly connected to the opposite side of the two movable plates 205, and a pressing block 207 is fixedly connected to the side of the movable plate 205 away from the spring 206.

[0032] Specifically, such as Figure 5 As shown, the top of the front and rear sides of the inner wall of the protective shell 201 is provided with positioning grooves 4 for use with fixing blocks 204, and the surface of fixing blocks 204 is in contact with the inner wall of positioning grooves 4. The top of the front and rear sides of the protective shell 201 is provided with positioning holes 5 for use with pressing blocks 207, and the positioning holes 5 are connected to the positioning grooves 4.

[0033] Specifically, such as Figure 5 As shown, bolts 6 are threadedly connected to both sides of the top of the fixed ring 202, and the bottom of the bolts 6 extends into the interior of the protective shell 201.

[0034] In this embodiment: the positioning hole 5 is connected to the positioning groove 4, so that the fixing block 204 can move smoothly under the restriction of the positioning groove 4. At the same time, the movement of the fixing ring 202 can be restricted, so that it is precisely connected to the protective shell 201. With the elastic action of the spring 206, the pressing block 207 can be driven to reset and precisely embedded in the positioning hole 5, thus completing the installation of the protective component 2. At the same time, under the action of the bolt 6, it can pass through the fixing ring 202 and be threadedly connected to the protective shell 201, forming a double-layer reinforcement with the pressing block 207, ensuring the stable operation of the protective component 2 during the processing and improving the convenience of using the protective component 2.

[0035] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, fixing plates 7 are fixedly connected to the four corners of the two annular dust collection plates 301, and reinforcing rods 8 are fixedly connected between the opposite sides of the two fixing plates 7 at the top and bottom.

[0036] Specifically, such as Figure 4 As shown, both sides of the inner wall of the storage box 306 are provided with sliding grooves 9 for use with the slider 307, and the inside of the sliding grooves 9 is fixedly connected with positioning plates 10. The front sides of the two positioning plates 10 are rotatably connected with buckle blocks 11, and the slider 307 is slidably connected to the surface of the positioning plates 10.

[0037] In this embodiment: the cooperation of the reinforcing rod 8 and the fixing plate 7 not only provides secondary reinforcement to the annular dust collection plate 301 to ensure its stable operation, but also resists external impacts and prevents the hydraulic cylinder body 1 from being damaged by external forces, thus improving the safety of the device. Then, the cooperation of the slider 307 and the slide groove 9 allows the slider 307 to move smoothly in the slide groove 9 under the restriction of the positioning plate 10, simultaneously driving the storage box 308 to move, achieving rapid dust removal. At the same time, under the action of the latching block 11, the slider 307 can be locked to form a mechanical lock, preventing the storage box 308 from shaking and falling due to external forces, ensuring the normal operation of the dust collection effect of the air-cooled dust collection component 3, and improving the ease of use of the air-cooled dust collection component 3.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, an audible and visual alarm 12 is fixedly connected to the left side of the bottom of the protective shell 201.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a temperature detector 13 is fixedly connected to the right side of the bottom of the protective shell 201, and the temperature detector 13 is electrically connected to the audible and visual alarm 12.

[0040] In this embodiment: the temperature detector 13 can monitor the operating temperature of the hydraulic cylinder in real time and transmit the data synchronously to the audible and visual alarm 12. When the temperature is abnormal, the audible and visual alarm 12 will generate a bright flashing light and a buzzer alarm to remind the operator to intervene in time to avoid equipment failure caused by high temperature, ensure smooth production, and improve the ease of use of the device.

[0041] Working principle: When the hydraulic cylinder is being processed, first, manually press the pressing block 207 to move the moving plate 205 smoothly and compress the spring 206, releasing the fixing of the protective component 2 and realizing the installation and removal of the protective shell 201. Then, after the protective shell 201 is sleeved on the hydraulic cylinder body 1, the fixing ring 202 is aligned with it. Under the elastic action of the spring 206, the pressing block 207 can be driven to reset, so that it is accurately embedded in the positioning hole 5 to complete the locking. Then, the bolt 6 is tightened to form a double-layer reinforcement with the pressing block 207. After installation, the hydraulic cylinder body 1 is started for processing. With the help of the heat dissipation plate 203, the heat generated by the hydraulic cylinder body 1 can be dissipated in time. Then, the fan 305 is started to generate suction, which is transmitted through the connecting hose 304, the dust collection main pipe 303 and the dust collection pipe 302. At the annular suction plate 301, an annular negative pressure zone is formed by the annular suction plate 301, which drives the surrounding air and dust to flow. This not only allows the dust generated during processing to flow into the storage box 306 through the annular suction plate 301, but also accelerates the airflow at the heat sink 203, achieving rapid cooling. At the same time, under the action of the temperature detector 13, the operating temperature of the hydraulic cylinder body 1 can be monitored in real time, and the data is transmitted synchronously to the audible and visual alarm 12. When the temperature is abnormal, the audible and visual alarm 12 will produce a bright flashing light and a buzzer alarm to remind the operator to intervene in time. Finally, after processing is completed, the locking block 11 is rotated to release the lock on the slider 307, so that the storage box 308 can be smoothly pulled out for cleaning. After cleaning, it is reset to restore the storage function of the air-cooled dust collection component 3.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
