Description

Technical Field

[0001] This utility model relates to the field of braking device technology, and in particular to a windproof control device for gantry cranes with wind force warning. Background Technology

[0002] Gantry cranes are mainly used for loading and unloading large outdoor goods. Their main structure is similar to a portal frame. Because there are two legs installed under the main beam, and the bottom of the legs is equipped with wheels that can travel on the corresponding tracks, gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability and strong versatility. As a result, gantry cranes have been widely used in cargo lifting and transportation.

[0003] During the operation of gantry cranes, which typically operate in open-air environments, they often face safety hazards posed by strong winds. Strong winds can cause serious accidents such as runaway, slippage, or even overturning of the gantry crane, damaging the equipment and endangering the lives of operators and surrounding personnel. Traditional windproofing measures, such as simple wheel clamps or rail clamps, are often ineffective in securing the gantry crane in strong winds, making it impossible to take preventative measures in advance. To address this technical problem, this application proposes a gantry crane windproof control device with wind force warning. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gantry crane windproof control device with wind force warning. This device aims to solve the problem that traditional windproof measures are difficult to effectively fix the gantry crane in strong winds and cannot take protective measures in advance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gantry crane wind prevention control device with wind force warning, comprising:

[0007] The housing has two slide rails fixedly connected to its rear bottom side. A guide base is slidably connected inside the slide rails. Two guide grooves are opened on the front side of the guide base. The two guide grooves are mirror-symmetrical and inclined. A traction rod is slidably connected inside the guide groove. The front end of the traction rod is connected to a clamping head through a clamping assembly to clamp and fix the traveling wheels of the gantry crane and restrict the rotation of the traveling wheels of the gantry crane.

[0008] A sliding seat is fixedly connected to the bottom side of the two slide rail frames. A sliding sleeve is slidably connected to the top side of the sliding seat. The rear end of the sliding sleeve is connected to the two traction rods through a traction component. When the two sliding sleeves are closed, the traction component pushes the sliding sleeve forward, causing the fixed limiting wedge at the front end of the sliding sleeve to abut against the gantry crane traveling wheel, further restricting the rotation of the gantry crane traveling wheel.

[0009] Furthermore, the clamping assembly includes a sliding frame fixedly connected to the front side of the slide rail frame. The bottom side of the sliding frame is supported and reinforced by a reinforcing frame. Clamping arms are slidably connected to adjacent sides of the two sliding frames. The rear side of the clamping arm is fixedly connected to the traction rod, and the front side of the clamping arm is fixedly connected to the clamping head.

[0010] Furthermore, the clamping arm is internally fixedly connected with multiple reinforcing columns to strengthen the clamping arm.

[0011] Furthermore, the traction assembly includes a rotating seat, the top of which is connected to the traction rod via two connecting rods, and the bottom of which is rotatably connected to a connecting rod, the front end of which is connected to the rear end of the sliding sleeve.

[0012] Furthermore, one end of each of the two connecting rods is rotatably connected to both ends of the rotating seat, and the other end of the connecting rod is rotatably connected to the rear side of the traction rod.

[0013] Furthermore, it also includes a hydraulic cylinder, which is installed at the middle of the housing, and the driving end of the hydraulic cylinder is fixedly connected to a connector, the rear end of which is fixedly connected to the top side of the guide base.

[0014] Furthermore, the front side of the limiting wedge and the outer wall of the clamping head are both provided with mesh protrusions for increasing friction.

[0015] Furthermore, the guide base is internally fixedly connected with a counterweight to increase its weight, thereby neutralizing the reaction force caused by the traveling wheels of the gantry crane and preventing the guide base from being lifted up after it descends.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model achieves dual braking of the gantry crane's traveling wheels, which can quickly and firmly clamp the traveling wheels and effectively prevent them from rotating. This dual braking method provides more reliable wind protection. At the same time, through the design of the limiting wedge and the mesh protrusions on the surface of the clamping head, the friction between the gantry crane and the traveling wheels is significantly increased, further enhancing the braking effect. Even in severe weather conditions, it can ensure that the gantry crane remains stable and effectively prevent various safety accidents caused by strong winds.

[0018] 2. This utility model features a simple and reasonable structural design, is easy to install and maintain, and can adapt to the needs of different types of gantry cranes. Its wind warning function allows operators to prepare protective measures in advance, buying valuable time for personnel evacuation and secondary equipment protection, greatly improving the safety and operational efficiency of gantry cranes in windy weather.

Detailed Implementation

[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] One embodiment of this utility model is provided:

[0028] A gantry crane wind prevention control device with wind force warning, comprising:

[0029] Reference Figure 1 , Figure 3 and Figure 4The housing 1 has two slide rail frames 2 fixedly connected to the bottom rear end. The slide rail frame 2 has a guide base 3 slidably connected inside. The guide base 3 has two guide grooves on the front side. The two guide grooves are mirror symmetrical and in an inclined state. The guide grooves have a traction rod 4 slidably connected inside. The front end of the traction rod 4 is connected to a clamping head 8 through a clamping assembly to clamp and fix the gantry crane traveling wheel 19 and restrict the rotation of the gantry crane traveling wheel 19. The clamping assembly includes a sliding frame 6 fixedly connected to the front side of the slide rail frame 2. The bottom side of the sliding frame 6 is supported and reinforced by a reinforcing frame 7. The two sliding frames 6 are slidably connected to a clamping arm 5 on the adjacent side. The rear side of the clamping arm 5 is fixedly connected to the traction rod 4, and the front side of the clamping arm 5 is fixedly connected to the clamping head 8. The clamping arm 5 has multiple reinforcing columns 9 fixedly connected inside to strengthen the clamping arm 5.

[0030] Specifically, after the guide base 3 descends, it slides on the slide rail 2. The guide groove on the guide base 3 guides the traction rod 4 to close, thereby causing the clamping arm 5 connected to the traction rod 4 and the clamping head 8 connected to the clamping arm 5 to close and move, reducing the distance between the two clamping heads 8 and clamping them onto the gantry crane traveling wheel 19, so that the gantry crane traveling wheel 19 is subjected to clamping pressure and is difficult to rotate.

[0031] Reference Figure 2 , Figure 3 and Figure 5 The sliding seat 13 is fixedly connected to the bottom side of the two slide rail frames 2. The top side of the sliding seat 13 is slidably connected to the sliding sleeve 14. The rear end of the sliding sleeve 14 is connected to the two traction rods 4 through the traction component. When the two sliding sleeves 14 are closed, the traction component pushes the sliding sleeve 14 forward, so that the fixed limiting wedge 15 at the front end of the sliding sleeve 14 abuts against the gantry crane traveling wheel 19, further restricting the rotation of the gantry crane traveling wheel 19. The traction component includes a rotating seat 11. The top end of the rotating seat 11 is connected to the traction rod 4 through two connecting rods 10. The bottom end of the rotating seat 11 is rotatably connected to a connecting rod 12. The front end of the connecting rod 12 is connected to the rear end of the sliding sleeve 14. One end of the two connecting rods 10 is rotatably connected to the two ends of the rotating seat 11 respectively. The other end of the connecting rod 10 is rotatably connected to the rear side of the traction rod 4.

[0032] Specifically, the closing sliding sleeve 14 pulls the two connecting rods 10, changing the included angle between them. This pushes the rotating seat 11 downward and the connecting rod 12 on the bottom side of the rotating seat 11, causing the rear end of the stressed connecting rod 12 to move downward and push the sliding sleeve 14 connected to the limiting wedge 15 on the front side. The sliding sleeve 14 then abuts against the gantry crane traveling wheel 19, further pressurizing and limiting the gantry crane traveling wheel 19, increasing friction, and preventing it from rotating. This prevents the gantry crane from running away, slipping, or overturning due to strong winds, ensuring safety. It can also fall and lock the wheels after strong winds or when the work is finished and the power is cut off, buying time for personnel evacuation and secondary protection.

[0033] Reference Figure 1 and Figure 3 It also includes a hydraulic cylinder 17, which is installed in the middle of the housing 1. The drive end of the hydraulic cylinder 17 is fixedly connected to a connector 18, and the rear end of the connector 18 is fixedly connected to the top side of the guide base 3. The hydraulic cylinder 17 is powered by an external circuit system. Under normal conditions, it is in an extended state. It drives the guide base 3 to be in a suspended state through the connector 18. The hydraulic cylinder 17 adopts a single-acting hydraulic cylinder specification with spring return. Only one chamber is filled with oil, and the other chamber is composed of a compression spring. When the power is on, the oil pressure overcomes the spring force to push the piston out. When the power is off, the oil pressure disappears, and the spring immediately pushes the piston back. When the wind sensor connected to the circuit system in the gantry crane detects that the wind force reaches level 5, the circuit system will receive a command to automatically cut off the power to the hydraulic cylinder 17, causing its drive end to retract, the guide base 3 to fall, and the gantry crane traveling wheel 19 to be braked.

[0034] The front side of the limiting wedge 15 and the outer wall of the clamping head 8 are provided with mesh protrusions to increase friction, so as to better resist and brake the gantry crane traveling wheel 19 and increase the friction of the clamping. A counterweight block 16 is fixedly connected to the inside of the guide base 3 to increase the weight, so as to neutralize the reaction force caused by the gantry crane traveling wheel 19 and prevent the guide base 3 from being lifted after descending. Most of the components are made of high-strength solid steel to resist the inertia generated by the movement of the heavy gantry crane, thereby increasing the reaction force of the gantry crane traveling wheel 19 and increasing the service life of the device.

[0035] Working principle: When the wind sensor in the gantry crane's electrical system detects a wind force of level 5, the electrical system receives a command and automatically cuts off the power to the hydraulic cylinder 17, causing its drive end to retract. The guide base 3, under the action of the counterweight 16 and the drive end of the retracted hydraulic cylinder 17 connected to the connector 18, falls and slides on the slide rail 2. The guide groove on the inclined guide base 3 guides the traction rod 4 to close, thereby causing the clamping arm 5 connected to the traction rod 4 and the clamping head 8 connected to the clamping arm 5 to close and shift, reducing the distance between the two clamping heads 8 and clamping... Holding onto the gantry crane's traveling wheel 19, the closed sliding sleeve 14 pulls the two connecting rods 10, changing the included angle between them. This pushes the rotating seat 11 downwards and moves the connecting rod 12 on the bottom side of the rotating seat 11. The rear end of the stressed connecting rod 12 moves downwards and pushes the sliding sleeve 14, which is connected to the limiting wedge 15, against the gantry crane's traveling wheel 19. This further presses against the traveling wheel 19, limiting its movement, increasing friction, and preventing it from rotating. This prevents the gantry crane from running away, slipping, or overturning due to strong winds, ensuring safety.

[0036] It is worth noting that the circuits, protection, and wind sensors involved in the above embodiments all adopt corresponding existing technologies according to the actual situation, and therefore will not be described in detail in the embodiments of this application.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
