Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to a crane operation parameter measuring device and a crane. Background Art

[0002] The measurement of crane operating parameters is crucial to ensure the safe, reliable and efficient operation of the equipment. By measuring and monitoring various operating parameters of the crane, potential failures, performance degradation and / or improper operation can be discovered in a timely manner, so that corresponding maintenance measures can be taken to prevent accidents and ensure the continuity and safety of operations.

[0003] At present, the existing crane operation parameter measurement devices mostly rely on various sensors to work during use. When the sensor detects an abnormality in the equipment, the sensor transmits information to the alarm structure through electrical signals to sound an alarm, and then the workers shut down the equipment. When more electronic equipment is in use, a failure in one place means that the entire measurement system is paralyzed, which is prone to major safety hazards. In addition, the detection equipment has a relatively single function and can only measure the parameters of the crane. When a problem occurs in the machinery, the device cannot be emergency braked.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing crane operation parameter measurement devices on the market, and even if they can be solved, they need to be solved through external tools, which makes it impossible to achieve the desired effect.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 , Figure 2 ,, Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 , the present invention provides a technical solution: a crane operation parameter measuring device, comprising a crane device body 1, a monitoring mechanism 2 is arranged outside the crane device body 1, and a limiting mechanism 3 is arranged outside the crane device body 1; The monitoring mechanism 2 includes a running speed monitoring unit 21 . The running speed monitoring unit 21 is arranged at the rear of the crane device body 1 . The running speed monitoring unit 21 can monitor the traveling speed of the crane device body 1 .

[0023] As a further limitation of the monitoring mechanism 2 of the present invention, the running speed monitoring unit 21 includes a rectangular box 2101, the front of the rectangular box 2101 is fixedly connected to the back of the crane device body 1, the inner wall of the crane device body 1 is rotatably connected to two rollers 2117, and two guide rails 2118 are arranged below the crane device body 1. The outer surface of each roller 2117 contacts the outer surface of the guide rail 2118, and the back of one of the rollers 2117 is fixedly connected to a transmission shaft 2116, and the outer surface of the transmission shaft 2116 is rotatably connected to the inner wall of the rectangular box 2101. The end of the transmission shaft 2116 away from the roller 2117 is fixedly connected to the first steering gear 2115, the outer surface of the first steering gear 2115 is meshed with the second steering gear 2114, the inner wall of the second steering gear 2114 is fixedly connected to the rotating shaft 2113, the outer surface of the rotating shaft 2113 is rotatably connected to the inner wall of the rectangular box 2101, the upper surface of the rectangular box 2101 is fixedly connected to the gear box 2103, the input end of the gear box 2103 is fixedly connected to the top of the rotating shaft 2113, and the output end of the gear box 2103 is fixedly connected to the rotating plate 211 9, a rotating block 2111 is fixedly connected to the upper surface of the rotating plate 2119, a first limiting groove 2105 is provided on the back of the crane device body 1, a first limiting block 2120 is slidably connected inside the first limiting groove 2105, a reciprocating plate 2121 is fixedly connected to the back of the first limiting block 2120, the inner circle of the reciprocating plate 2121 contacts the outer surface of the rotating block 2111, a driving block 2112 is fixedly connected to the inner wall of the reciprocating plate 2121, a square plate 2104 is fixedly connected to the back of the crane device body 1, and two sets of guides are fixedly connected to the upper surface of the square plate 2104. Guide blocks 2109, each group of guide blocks 2109 has two guide blocks, each group of guide blocks 2109 is slidably connected with a first round ball 2108, the front and back of the square plate 2104 are respectively fixedly connected with a first traction tube 2102 and a second traction tube 2106, and the outer surface of the second traction tube 2106 is fixedly connected with a knocking tube 2122. By setting the running speed monitoring unit 21, the running speed monitoring unit 21 can monitor the travel speed of the crane device body 1, so as to avoid the problem of excessive travel speed of the crane device body 1, which may cause certain safety hazards; See also Figure 8 Two groups of slots 2110 are provided on the upper surface of the square plate 2104, and each group of slots 2110 has two slots. A baffle 2107 is clamped inside each group of slots 2110, and the bottom surface of each baffle 2107 is in contact with the upper surface of the guide block 2109. By providing the slots 2110 and the baffle 2107, the baffle 2107 covering the guide block 2109 can be removed by using the slots 2110, and the baffle 2107 can limit the first circular ball 2108 inside the guide block 2109 to prevent the first circular ball 2108 from moving upward.

[0024] The specific implementation of this embodiment is as follows: when the device is needed, the crane device body 1 can be controlled to operate, and the crane device body 1 will move along the guide rail 2118. When the crane device body 1 is moving, the power generated by the rotation of the roller 2117 will be transmitted to the first steering gear 2115 through the transmission shaft 2116. There is a meshing relationship between the first steering gear 2115 and the second steering gear 2114, so the second steering gear 2114 will drive the rotating shaft 2113 to rotate, and The rotating shaft 2113 transmits power to the inside of the gear box 2103, and the gear transmission structure inside the gear box 2103 converts the input power into power with a faster rotation speed and transmits it to the rotating plate 2119. The rotating block 2111 fixed on the upper surface of the rotating plate 2119 rotates with the rotating plate 2119, and the rotating block 2111 is located at the edge of the rotating plate 2119. Therefore, the rotating block 2111 will rotate around the center of the rotating plate 2119 in a large range, and the rotating block 2111 is on the reciprocating plate. 2121, so when the rotating block 2111 drives the reciprocating plate 2121 to move back and forth, the driving block 2112 fixed on the inner wall of the reciprocating plate 2121 will slide inside the square plate 2104, thereby driving the two first round balls 2108 to roll forward or backward respectively. It should be understood that the rolling distance of the first round balls 2108 is determined by the moving speed of the driving block 2112, that is, the rolling speed of the roller 2117. Therefore, when the device is initially set up, it is necessary to ensure that the device moves at a normal speed. When the crane device body 1 is moving, the force converted by the gear transmission 2103 is not enough to drive the first round ball 2108 to roll down to the descending stage of the first traction tube 2102. When the crane device body 1 moves at a high speed, the force converted by the gear transmission 2103 can drive the first round ball 2108 to roll down to the descending stage of the first traction tube 2102. Similarly, when the crane device body 1 moves too fast, the first round ball 2108 inside the second traction tube 2106 will hit the second traction tube 2106 to issue a warning to the outside world.

[0025] Example 2: Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 The present invention provides a technical solution: a crane operation parameter measuring device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The monitoring mechanism 2 also includes an acceleration monitoring unit 22. The acceleration monitoring unit 22 is arranged in front of the crane device body 1. The acceleration monitoring unit 22 cooperates with the operation speed monitoring unit 21. The acceleration monitoring unit 22 can monitor the acceleration of the crane device body 1.

[0026] As a further limitation of the monitoring mechanism 2 of the present invention, the acceleration monitoring unit 22 includes a reaction box 2201, the back of the reaction box 2201 is fixedly connected to the front of the crane device body 1, the two side surfaces of the reaction box 2201 are fixedly connected to a third traction tube 2213, the inner bottom wall of the reaction box 2201 is provided with a circular groove 2219, and a second circular ball 2220 is arranged inside the circular groove 2219, and the outer surface of the second circular ball 2220 contacts the inner wall of the reaction box 2201, and the left side of the crane device body 1 is fixedly connected to a reaction box 2202, and the inner wall of the reaction box 2202 is fixedly connected to two partitions 2218, and the bottom surface of each partition 2218 is fixedly connected to a force spring 220. 8. The bottom ends of the two force springs 2208 are fixedly connected with a limiting block 2211, the upper surface of the limiting block 2211 is fixedly connected with a lifting block 2209, the interior of the lifting block 2209 is slidably connected with a moving block 2214, the inner wall of the moving block 2214 is fixedly connected with a strong magnet 2215, the bottom ends of the first traction tube 2102 and the third traction tube 2213 are both penetrated into the interior of the reaction box 2202, by setting an acceleration monitoring unit 22, the acceleration monitoring unit 22 cooperates with the running speed monitoring unit 21, the acceleration monitoring unit 22 can monitor the instantaneous acceleration of the crane device body 1, and make a braking response, thereby reducing the collapse problem caused by the failure of the mechanical device body; See also Figure 5 The inner wall of the lifting block 2209 is rotatably connected with three rollers 2216, and the outer surface of each roller 2216 is in contact with the upper surface of the moving block 2214. By providing the rollers 2216, the rollers 2216 can reduce the resistance encountered by the moving block 2214 during movement, so that the moving block 2214 can be more easily separated from the range of the lifting block 2209; See also Figure 5 The left side of each partition plate 2218 is provided with two second limiting grooves 2212, and the interior of each second limiting groove 2212 is slidably connected with a second limiting block 2210, and the side of each two second limiting blocks 2210 close to each other is fixedly connected with a sliding block 2217, and the upper surfaces of the two sliding blocks 2217 are respectively in contact with the bottom end of the first traction tube 2102 and the bottom end of the third traction tube 2213. 210 and the sliding block 2217, by using the second limiting block 2210 to slide inside the second limiting groove 2212, the sliding block 2217 can be limited and supported, so that the sliding block 2217 is installed inside the partition 2218. In addition, when it is necessary to take out the first round ball 2108 and the second round ball 2220, the sliding block 2217 can be pulled to move, so that the first round ball 2108 and the second round ball 2220 can fall into the lower half of the reaction box 2202; See also Figure 3 A protective plate 2203 is provided inside the reaction box 2202, and the outer surface of the protective plate 2203 is in contact with the inner wall of the reaction box 2202. By providing the protective plate 2203, the protective plate 2203 can be used to protect the equipment inside the reaction box 2202, thereby preventing the equipment inside the reaction box 2202 from being damaged; See also Figure 3 , two third limiting grooves 2207 are provided on the left side of the reaction box 2202, and a third limiting block 2204 is slidably connected inside each third limiting groove 2207, and the side surfaces of the two third limiting blocks 2204 close to each other are fixedly connected to the front and back sides of the protective plate 2203 respectively. By providing the third limiting grooves 2207 and the third limiting blocks 2204, the third limiting grooves 2207 can be used to limit the third limiting blocks 2204, so that the protective plate 2203 can only move inside a specific track; See also Figure 3 The inner wall of the reaction box 2202 is rotatably connected to two limit shafts 2206, and the left end of each limit shaft 2206 is fixedly connected to the limit plate 2205. The right side of each limit plate 2205 is in contact with the left side of the protective plate 2203 and the left side of the reaction box 2202. By setting the limit plate 2205 and the limit shaft 2206, the rotation of the limit shaft 2206 can determine the position of the limit plate 2205, and the limit plate 2205 can limit the position of the protective plate 2203.

[0027] The specific implementation of this embodiment is as follows: when the device accelerates too fast, the inertia generated in an instant will drive the second round ball 2220 to move out of the circular groove 2219, so that the second round ball 2220 rolls into the reaction box 2202 through the third traction tube 2213. No matter whether the first round ball 2108 in the first traction tube 2102 or the second round ball 2220 in the third traction tube 2213 falls into the reaction box 2202, they will eventually fall on the sliding block 2217. The first round ball 2108 and the second round ball 2220 are both made of iron. Therefore, the strong magnet 2215 will be attracted by the first round ball 2108 and the second round ball 2220. When the strong magnet 2215 drives the moving block 2214 to move, the existence of the roller 2216 will reduce the resistance encountered by the moving block 2214 during movement. When the moving block 2214 completely moves out of the range of the lifting block 2209, the lifting block 2209 and the limiting block 2211 will move downward under the action of the force spring 2208, and the contact between the limiting block 2211 and the guide rail 2118 will increase the resistance encountered by the crane device body 1 during movement, thereby allowing emergency braking.

[0028] Example 3: Please refer to Figure 1 , Figure 3 and Figure 4 The present invention provides a technical solution: a crane operation parameter measuring device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The limiting mechanism 3 cooperates with the monitoring mechanism 2. The limiting mechanism 3 can prevent the operating speed monitoring unit 21 and the acceleration monitoring unit 22 from simultaneously triggering the braking device of the crane device body 1.

[0029] As a further limitation of the limiting mechanism 3 of the present invention, the limiting mechanism 3 includes a stepper motor 301, the right side of the stepper motor 301 is fixedly connected to the left side of the crane device body 1, the output end of the stepper motor 301 is fixedly connected to a rotating shaft 302, the outer surface of the rotating shaft 302 is rotatably connected to the inner wall of the reaction box 2202, the outer surface of the rotating shaft 302 is fixedly connected to a circular plate 303, the outer side of the circular plate 303 is provided with an annular magnet 305, the outer surface of the annular magnet 305 is fixedly connected to a fixed plate 304, and the fixed plate 304 The outer surface is clamped to the inside of the circular plate 303, and the inside of the fixed plate 304 and the inside of the circular plate 303 are jointly clamped with a fixed shaft 306. By setting a limiting mechanism 3, the limiting mechanism 3 can prevent the first circular ball 2108 and the second circular ball 2220 from reacting with the strong magnet 2215 at almost the same time. By setting an operating speed monitoring unit 21, an acceleration monitoring unit 22 and a limiting mechanism 3, the problem of the device having a relatively single function and being unable to perform emergency braking on faulty equipment during use can be effectively avoided.

[0030] The specific implementation of this embodiment is as follows: In addition, since the movement of the limiting block 2211 is determined by the strong magnet 2215, when the first round ball 2108 and the second round ball 2220 fall into the vicinity of the strong magnet 2215 at about the same time, both ends of the strong magnet 2215 are attracted by the magnetic force, so it is impossible to completely move the moving block 2214 out of the range of the lifting block 2209, so the limiting block 2211 cannot perform emergency braking on the crane device body 1. Therefore, when the crane device body 1 is in use, it is necessary to control the stepper motor 301 to run, and the operation of the stepper motor 301 will drive the rotating shaft 302 fixed at the output end. The circular plate 303 and the annular magnet 305 rotate, and the rotating shaft 302 also drives the circular plate 303 and the annular magnet 305 to rotate. Since the annular magnet 305 only covers half of the circular plate 303, the annular magnet 305 will provide magnetic force to the falling circular ball no matter where it is. Therefore, when the first circular ball 2108 and the second circular ball 2220 roll down at about the same time, the annular magnet 305 will inevitably adsorb one of them, so that the other circular ball can smoothly pull the moving block 2214 to completely move out of the range of the lifting block 2209, so that the lifting block 2209 and the limiting block 2211 can smoothly limit the crane device body 1.
