Description

Technical Field

[0001] The present invention relates to the technical field of tire crane monitoring, in particular to a tire crane leveling safety monitoring device. Background Art

[0002] Tire-mounted gantry cranes are a type of lifting equipment widely used in outdoor and large-scale operations. Due to the mobility of their tires, tire-mounted gantry cranes can be moved over a larger area, making it convenient to transfer from one work point to another without disassembly and reinstallation. Tire-mounted cranes are widely used in actual cargo yards and other scenarios, and can be used to transport construction materials. The current tire-mounted crane leveling safety monitoring device is not convenient for automatically adapting to the ground to monitor the safety of the moving path. The normal slope of the ground has a great impact on leveling monitoring, and it is easy to cause safety hazards such as tire collapse in wet areas. At the same time, it is not convenient to automatically detect and control support protection after small potholes exist on the ground, which affects the flexibility of the crane. It requires manual work that consumes time and effort to fill or pad, and also affects the moving efficiency. It is also not convenient for explosion-proof protection work. Once a tire bursts and the hoisted cargo is added, it is easy to affect the stability of the crane. At the same time, the explosion-proof monitoring is not comprehensive, and the traditional tire pressure detection method is greatly affected by the tire base pressure.

[0003] Therefore, we propose a tire crane leveling safety monitoring device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention utilizes a ground-attached detection component that is attached to the ground, thereby maintaining detection accuracy and avoiding detection errors caused by normal fluctuations of the ground. It can better detect the flatness of the ground and reduce the misjudgment rate. At the same time, this structure can control the tire crane to stop in time, which can reduce safety hazards. The use of a laser light can assist workers in detecting the spacing accuracy between the two tires of the tire crane, avoiding changes in tire distance due to factors such as long-term use, that is, gantry deformation is not discovered. The laser detection method does not affect the flexibility of the tire crane and is intuitive and accurate.

[0017] The filling detection part can be used to detect the size of the wet area or the sunken area. After detecting the wet area that meets the standards, the supporting steel bars can be automatically discharged on the ground in conjunction with the padding support parts, which can improve the tire operation safety of the tire crane. The supporting steel bars are used to increase the tire contact area, improve the tire stability, and avoid the poor safety of manual operation of the pad. This structure can ensure that the padding work is carried out only after the tire meets the standards after the padding support steel bars are passed normally, avoiding the problem that traditional manual labor is difficult to accurately and directly determine whether the traffic conditions are met.

[0018] The use of explosion-proof monitoring parts can be used for real-time explosion-proof monitoring work, which can avoid tire blowouts caused by excessive tire compression, and avoid the problem that traditional tire pressure detection methods are difficult to accurately judge the degree of tire compression. Long-term excessive tire compression or overloading will increase wear. The tire crane can be automatically controlled to stop operating after a tire explosion to prevent continuous displacement, especially when lifting goods, which causes excessive center of gravity deviation and increases the risk of overturning. At the same time, explosion-proof support parts can be used for support to improve the overall stability of the tire crane after a tire blowout, reduce the load-bearing capacity of the remaining tires, and ensure safety.

[0035] Among them, the monitoring installation part 1 includes: a baffle 103, a laser light 104 and an indicator light 105, and the baffle 103 is fixedly installed on the side of the front end cover 1011; a ring scale is provided on the baffle 103; a laser light 104 is fixedly installed on the rear end cover 1011, and the laser light 104 is used to illuminate the baffle 103; the two swing arms 102 are respectively fixedly installed with indicator lights 105; the ground detection part 2 includes: a ground axis frame 201 and a ground wheel 202, the two swing arms 102 are rotatably mounted with a ground axis frame 201, and the ground axis frame 201 is rotatably mounted with two ground wheels 202; the ground wheel 202 is used to adhere to the ground and roll to guide; the wet detection part 3 includes: a downward pressing connecting shaft 301, a downward pressing frame 302, an extrusion switch 303, a needle wheel 304, a power connection piece 305 and a contact plate 30 6. Two downward pressing connecting shafts 301 are slidably installed on the ground-contacting shaft frame 201; the two downward pressing connecting shafts 301 are located between the two ground-contacting wheels 202; a downward pressing frame 302 is fixedly installed at the bottom of the two downward pressing connecting shafts 301; tension springs are respectively sleeved on the two downward pressing connecting shafts 301, and the tension springs on the two downward pressing connecting shafts 301 are connected between the two downward pressing connecting shafts 301 and the ground-contacting shaft frame 201; an extrusion switch 303 is fixedly installed on the top of the downward pressing frame 302, and the extrusion switch 303 is located at the bottom of the ground-contacting shaft frame 201; two pin wheels 304 are rotatably installed at the bottom of the downward pressing frame 302, and the surfaces of the two pin wheels 304 are provided with raised needles; an electric connection sheet 305 is fixedly installed on the side of the downward pressing frame 302; an electric contact plate 306 is fixedly installed on the bottom of the ground-contacting shaft frame 201, and the side of the electric contact plate 306 is provided with a conductive coating;The tire crane drive motor, the power supply of the connecting plate 305 and the contact plate 306 are connected in series. The wet-sinking detection part 3 can be used to detect the safety of the ground moving path to avoid large potholes on the ground or wet-sinking terrain on the ground, which may cause the tire to sink due to failure to detect it in time, or even cause safety hazards such as center of gravity shift. This structure can use the ground-contacting detection part 2 to stick to the ground to maintain detection accuracy and avoid detection errors caused by normal ups and downs of the ground. It can better detect the flatness of the ground and reduce the misjudgment rate. At the same time, this structure can control the tire crane to stop in time, which can reduce safety hazards. The laser light 104 can assist the staff in detecting the spacing accuracy between the two tires of the tire crane to avoid long-term use, etc. To prevent variations in tire distance caused by factors, that is, gantry deformation goes undetected, achieving precise leveling detection, laser projection can be used for direct detection. When the distance between the two tires is standard, the laser light 104 can illuminate the baffle 103. If, during use, the tire crane gantry deforms and the leveling deformation deviates, and the distance and concentricity of the two tires deviate, the laser point of the laser light 104 will not illuminate the center of the baffle 103, providing an intuitive prompt. At the same time, when the tire crane moves, the swing arm 102 can drive the two ground-contacting wheels 202 to contact the ground simultaneously under the torsion of the torsion spring, regardless of the position of the tire crane. At this time, if there is a sag or sink in the ground, the sag or sink can be accurately detected.

[0036] Among them, the filling detection part 4 includes: a local test shaft 401, a side panel 4011 and a power strip 402, the local test shaft 401 is slidably installed on the lower pressure frame 302; the side panel 4011 is fixedly installed on the side of the lower pressure frame 302; a tension spring is sleeved on the outside of the local test shaft 401, and the tension spring on the outside of the local test shaft 401 is connected between the local test shaft 401 and the lower pressure frame 302; the side panel 4011 is fixedly installed on the side of the power strip 402; the bottom of the local test shaft 401 is an inclined structure; the filling detection part 4 also includes: a power ring 403, a power ring 403 is fixedly installed on the top of the local test shaft 401, and the power ring 403 is in contact with the power strip 402; the pad support 5 includes: a discharge shell 501, a support steel bar 502, a limit The positioning shaft 503 and the limiting electromagnet 504, the length of the supporting steel bar 502 is greater than the width of the tire, and the discharge shell 501 is fixedly installed between the two swing arms 102; the discharge shell 501 is a hollow structure; a row of supporting steel bars 502 are slidably placed inside the discharge shell 501; a row of supporting steel bars 502 are used to support the tires respectively; the limiting shaft 503 is slidably installed on the discharge shell 501, and a spring is connected between the top of the limiting shaft 503 and the discharge shell 501; the limiting electromagnet 504 is fixedly installed at the bottom of the limiting shaft 503; the bottom of the limiting electromagnet 504 magnetically attracts the discharge shell 501; the limiting electromagnet 504, the power strip 402, the power ring 403 and the extrusion switch 303 are connected in series with the power supply, and the filling detection piece 4 can be used to detect wet areas or sunken areas The size of the domain can be used to detect the wet-sink area that meets the standard. In conjunction with the padding support 5, the support steel bar 502 can be automatically discharged on the ground, which can improve the tire operation safety of the tire crane. The support steel bar 502 is used to increase the tire contact area and improve the tire stability. No manual operation is required, and at the same time, it avoids the poor safety of manual operation of the pad. The support steel bar 502 of this structure is direct and fast. This structure can ensure that the padding work is carried out only after the tire passes the standard normally after the support steel bar 502 is padded, avoiding the problem that traditional manual labor is difficult to accurately and directly identify whether the traffic conditions are met. When the needle wheel 304 rolls on the ground to detect wet-sink, if the needle wheel 304 itself does not sink within the width range of the needle wheel 304, and the width of the needle wheel 304 is small For the tire, if there is a small wet area below the needle wheel 304 at this time, if the local test shaft 401 is inserted into the soil due to the wet area below, the tension spring on the local test shaft 401 will squeeze the local test shaft 401. At this time, the power ring 403 will move down and separate from the power bar 402. At this time, the needle wheel 304 has not sunk, indicating that the wet area meets the standard for supporting the movement of the tire crane. At this time, the squeezing switch 303 is in a squeezed state and the safety switch is turned on. It is necessary to meet the requirement that when the squeezing switch 303 is pressed, the power ring 403 moves down and separates from the power bar 402, and the limit electromagnet 504 will be de-energized to release the stop. At this time, the support steel bar 502 will be discharged from the discharge shell 501 to perform the support work and improve the tire operation support stability.

[0037] Example 2, on the basis of Example 1, the explosion-proof support member 6 includes: a counterweight rod 601 and a support bar 602, the counterweight rod 601 is rotatably mounted on the two end caps 1011; the bottom of the two counterweight rods 601 are fixedly mounted with support bars 602, and the two ends of the two support bars 602 are inclined structures; the support bars 602 are spaced apart from the ground; the explosion-proof monitoring member 7 includes: a monitoring tube 701, a sliding adapter column 702 and a pressure switch 703, the monitoring tube 701 is fixedly mounted on the front counterweight rod 601; a spring is provided inside the monitoring tube 701; a sliding adapter column 702 is slidably mounted inside the monitoring tube 701, and the sliding adapter column 702 is slidably mounted inside the monitoring tube 701. The column 702 is connected to the spring side provided inside the monitoring tube 701; a pressure switch 703 is fixedly installed on the inner side of the sliding adapter column 702; the pressure switch 703 is located inside the monitoring tube 701; the pressure switch 703 is electrically connected to the indicator light 105; a gap is provided between the pressure switch 703 and the inner side of the monitoring tube 701; the explosion-proof monitoring component 7 also includes: a separation switch 704 and a fitting column 705, the separation switch 704 is electrically connected to the tire crane drive motor; the separation switch 704 is fixedly installed on the front side of the sliding adapter column 702; a fitting column 705 is slidably installed on the monitoring tube 701; the tail of the fitting column 705 squeezes and fits the separation switch 704; the fitting A ball is embedded in the end of the fitting column 705; the ball at the front end of the fitting column 705 is used to fit the side of the tire. The explosion-proof monitoring component 7 can be used for real-time explosion-proof monitoring, which can avoid tire blowouts caused by excessive tire squeezing. It can monitor the outside of the tire in real time. This structure can directly test the degree of tire squeezing deformation, which can avoid the problem that traditional tire pressure detection methods are difficult to accurately judge the degree of tire squeezing. Long-term excessive squeezing or overloading of tires will affect the service life of the tires, the wheel rims or the edges of the tires will increase wear, and it is necessary to increase the tire pressure or perform maintenance in time. In addition, the tire crane can be automatically controlled to stop operation after the tire explodes to prevent continuous Displacement, especially when hoisting goods, causes excessive deviation of the center of gravity, increasing the risk of overturning. At the same time, the explosion-proof support member 6 can be used for support to improve the overall stability of the tire crane after a tire blowout, reduce the load-bearing of the remaining tires, and ensure safety. If factors such as overload of the hoisted goods cause the bottom side area of ​​the tire to be excessively squeezed and the degree of outward protrusion increases, thereby squeezing the separation switch 704. At this time, the indicator light 105 can be controlled to light up as a prompt. At the same time, once the tire blows out, the separation switch 704 can control the tire crane drive motor to cut off the power and stop moving forward. At this time, the support bar 602 will also support under the blown tire to prevent the wheel rim from directly squeezing the tire.

[0038] The working principle of this embodiment: First, this structure can adopt four, that is, eight detection connecting shafts 101 as a group, which are fixed on both sides of the tire cover or tire bracket by bolts. At this time, the laser light 104 can be turned on to project on the baffle 103 installed on the adjacent tire cover. When the distance between the two tires is normal, the laser light 104 can be irradiated in the middle of the baffle 103. At this time, if the tire crane gantry is deformed and the level deformation deviation occurs during use, and the distance and concentricity of the two tires deviate, the laser point of the laser light 104 cannot be irradiated on the center position of the baffle 103, which can be intuitively prompted. At the same time, when the tire crane moves, the swing arm 102 can be Under the torsion force of the torsion spring, the two ground-contacting wheels 202 are driven to adhere to the ground at the same time, and are not affected by the position of the tire crane. At this time, if the ground is concave or wet, the pinwheel 304 on the lower pressure frame 302 can adapt to the concave or sink into the wet soil under the pressure of the tension spring on the lower pressure connecting shaft 301. At this time, the lower pressure frame 302 drives the power-connecting piece 305 to slide and separate from the electric contact plate 306. At this time, the tire crane drive motor can be controlled to cut off power and stop moving forward; if there is a small wet area below the pinwheel 304, at this time, if the local test shaft 401 is inserted into the soil due to the wet area below, under the pressure of the tension spring on the local test shaft 401, the power-connecting ring 403 will move downward. The pin wheel 304 is not sunken at this time, indicating that the wet area meets the standard of supporting the movement of the tire crane, that is, the squeeze switch 303 is in a squeezed state at this time, and the safety switch is turned on. It is necessary to meet the requirement that when the squeeze switch 303 is pressed, the power ring 403 moves down and separates from the power bar 402, and the limit electromagnet 504 is powered off. Under the pressure of the spring on the limit shaft 503, the limit shaft 503 can move up and release the stop. At this time, the support steel bar 502 will be discharged from the discharge shell 501 under the action of gravity to perform the supporting work. The support steel bar 502 can be added manually from the top of the discharge shell 501 to improve the support stability of the tire operation. As the tire crane moves The counterweight rod 601 can remain vertical under its own weight. At this time, if the hoisted cargo is overloaded or other factors cause the bottom side area of ​​the tire to be excessively squeezed and the degree of outward protrusion increases, it will squeeze the fitting column 705, and the spring inside the monitoring tube 701 will be compressed, thereby squeezing the separation switch 704. At this time, the indicator light 105 can be controlled to light up as a prompt. At the same time, once the tire bursts, the fitting column 705 loses the tire side squeezing limit, and the separation switch 704 can no longer be squeezed. At this time, the separation switch 704 can control the tire crane drive motor to cut off the power and stop moving forward. At this time, the support bar 602 will also support the bottom of the burst tire to prevent the wheel rim from directly squeezing the tire, thereby playing a supporting and protective role.
